Orthopraxy In Islam Essays - Islam, Hajj, Monotheistic Religions

Orthopraxy In Islam Orthopraxy in Islam RLST 2600 Orthopraxy in Islam Islamic life is centered on the physical practice of prayer (salat). With that the religion of Islam itself is based in the methodical movement through which Muslims show their devotion to Allah. The prayer begins with the devotee standing, bending slowly into a sitting position and ending in full prostration. Bowing fully onto the ground is a practice that shows humility and represents the true devotion of members. Practice-centered religion differentiates itself from orthodox religion in that it focuses primarily on ritual practice, rather than theology or doctrine, orthodox meaning correct opinion. The most visible orthodox religion of America is Christianity. Christianity centers life around the opinions of the church with less emphasis on purity and behavior. Islamic life is distinctly based on what can be defined as orthopraxy or the importance of religious practice. The orthopraxy of Islam can be seen in at least three of the Five Pillars of Islam , salat, Ramadan and the hajj, which are also representative of Muslim faith and duties. Salat, as mentioned earlier, is the performance of prayer five times a day. The prayer, which includes full prostration, is performed facing Mecca. In the The Meaning of the Glorious Koran, (the earliest source of Islamic writing as dictated to Mohammed), it is written, Whencesoever thou comest forth (for prayer, O Mohammed) turn thy face toward the Inviolable Place of Worship. Lo! it is the Truth from thy Lord. Allah is not unaware of what ye do (Surah 2:149). Implicit directions for prayer also display the amount of emphasis on practice. Salat must be performed five times daily, at specific times of the day: early morning, noon, mid-afternoon, sunset, and evening. Each Friday a congregational service is held at the mosque and every male is required to attend. Before prayer, four ritual aspects are required: ritual purification, proper covering of the body, proper intention, and facing Mecca, o r qibla (1). The emphasis on purity is directly associated with prayer, as one must not be impure in any way when one prays. The ritual impurity associated with everyday living is known as najasa or hadath. Najasa is external impurity including but not limited to, urine, blood, pus, feces of animals and humans. Hadath is impurity of the soul from performing certain activities. Hadath is caused by activities ranging from sleeping to seminal emission. The degree of hadath varies depending on the activity. Daily impurities result in a need for cleansing or ablutions. Ablution can be performed outside of mosques, usually the mosque will maintain a small fountain in which people can wash their hands to their elbows, feet to their ankles as well as heads and faces (1). The use of ablution as a form of purification as well as the consistent call to purify oneself follows the orthopraxy within Islam. The Koran states, The month of Ramadan in which was revealed the Quran, a guidance for mank ind, and clear proofs of the guidancewhosoever of you is present, let him fast the month (2:185). The fasting during the month of Ramadan is an expression of joy; the fasting person recalls their dependence on Allah for sustenance and life. The fast lasts for thirty days, each day from sunrise to sunset. Again, the emphasis is placed on the practice of refraining from food, which challenges the body (1). The lives of Muslims change for a month as they devote themselves to concentration on the past year, and the graciousness of God. Increasing the amount of time spent focusing on religion allows members of the religion to renew their faith and their relationships with others. The journey to Mecca known as the hajj encompasses the practicing element of Islam. The holy pilgrimage to Mecca is required for all Muslims only if they have the means to afford such a trip and the physical ability to do so. Borrowing money is not proper for the trip; in fact one must have all debts settled bef ore they leave on hajj. Travel to the center of religious worship represents the distance one is willing to travel as well as the costs one is willing to endure in order to display their

Whats Actually Tested on the ACT Science Section Skills and Topics

What's Actually Tested on the ACT Science Section Skills and Topics SAT / ACT Prep Online Guides and Tips Are you studying for the ACT? Not sure what to expect from the science section? You might be surprised to know that the science section one of the most commonly misunderstood parts of the ACT. So what exactly is tested on the ACT science section? And how much science do you need to know to do well? We'll break down this section for you with example questions so you know exactly what to expect. ACT Science Section Format The ACT science section is 35 minutes long and contains 40 questions. That means that you have about 53 seconds to spend on each question. The science section’s format is more like the reading section than the math section – which is surprising for some students! Each question on the math section has its own task or problem. But for both the ACT Reading and ACT Science, you have to read a passage and then answer a series of questions about it. There are seven passages on the science section. Each passage could contain graphs, charts, experiment summaries, or conflicting viewpoints from scientists. Every passage is followed by four to seven questions about it. So to do well on this section, you need to be able to quickly but accurately read and understand scientific data. What Does AP Science Test You On? Although the ACT Science section includes a wide range of science content, it tests your scientific skills more than your knowledge. As the ACT puts it, â€Å"the Science Test †¦ measures the interpretation, analysis, evaluation, reasoning, and problem-solving skills required in the natural sciences.† In other words, the science section tests skills, not specific facts or topics. So how exactly do you learn these science skills? From taking science classes in high school. The ACT website recommends you take at least three years of science in high school, and have taken at least one biology course and one physical or earth science course by the time you take the test. Aside from being more fun than the average class, doing science experiments helps you prepare for the ACT! By taking science courses, you’ll learn about the scientific method, how to collect and analyze data, and how to evaluate a theory or hypothesis. These skills will help you succeed on ACT Science. By taking biology and earth science, you'll get enough background on science terminology to be able to process ACT Science topics. Content you're tested on could include biology, chemistry, physics, and earth/space sciences (including geology, astronomy, and meteorology). As an example, the Preparing for the ACT official practice test science section includes passages about finch beak depth, the process of ions being precipitated from the earth’s atmosphere, cloud cover, acid-base titration, stellar evolution (how stars evolve), and the human threshold of hearing. However, the ACT does not expect students to be experts on such a wide variety of science topics. Using these kinds of topics as starting points, the science section will ask questions about data representation, the research process, and conflicting hypotheses. So if your scientific reasoning skills are strong, you will be able to answer any ACT Science question – even if it’s about an obscure topic like finch beak depth! That said, science background from biology, earth sciences, and chemistry will be helpful, because you won’t be intimidated by scientific terminology on the test. As an example, it will be easier to break down a passage about finch beak depth if you are familiar with the concept of natural selection. But remember you don’t actually need an advanced knowledge of particular science concepts to do well on this section – you just need to be able to read and interpret graphs and studies. Now let’s explore the exact question types you will see on ACT science. ACT Science Question Types There are three different question types you will see on ACT science. The majority of questions focus on having you break down data and experiments, though you will also have to compare conflicting viewpoints between scientists. Check out the three different question types below to learn more. #1: Data Representation (30-40% of Questions) These questions have you read graphs, interpret scatterplots, and explain information presented in tables. While some knowledge of the subject being tested is helpful, what is more important is your ability to read and understand data. As an example, check out this question from an ACT practice test: Source: ACT Assessment Practice Multiple Choice Test, 2004. The topic of this passage is metamorphic rock formation. However, you don't need to be an expert on that, or even know much about metamorphic rocks at all, to break down the chart. The question asks you which conditions a Facies G rock is most likely to form under. Looking at the area of the chart representing Facies G rocks, you can see they form with pressure between roughly 10 and 14 kb, and temperatures between 200 and 1,000 degrees Celsius. Looking at the answer choices, only one (choice J) lists a pressure reading that a Facies G rock could form under. Therefore J is the correct answer. In other words, the question is testing your ability to read and interpret the graph. The question is not testing your knowledge of metamorphic rocks. #2: Research Summaries (45-55% of Questions) These questions require you to interpret the design and results of experiments. Again, specific content knowledge isn't as important as knowledge of the scientific method and data collection. Check out this example question to see what we mean. The topic of this passage is elaiosomes, nutritious structures in seeds that attract ants. However, you don't need to know much about ants, seeds, or elaiosomes to break down this study and know which variable was controlled. A controlled variable is a variable that remains constant. So all you're looking for is the variable in the experiment that was kept the same. Reading the study description, we see that "Two seed dishes were placed in each site." This makes G the correct answer. (The other answer choices, number of ants, mass of elaiosome of each seed, and type of seed taken by the ants, were not described as constant in the study summary.) So to get this question right, you have to know what a controlled variable is and how it relates to scientific study structure. You do not have to be an expert on ants or seed germination. This is why taking science classes and becoming knowledgeable in the scientific method is so important to doing well on ACT science. #3: Conflicting Viewpoints (15-20% of Questions) The final question type on the ACT science section tests your ability to understand, analyze, and compare alternate viewpoints or hypotheses. These questions will center around a single situation or problem, and you will read two different viewpoints and compare the similarities and differences. Check out the example below. The question is asking you to figure out the main point of disagreement between the two scientists. In this case, the disagreement becomes clear in the first sentence of each opinion. Scientist 1 says "the object was a comet," while Scientist 2 says "the object was a stony asteroid." This makes answer choice J ("the type of object that entered Earth's atmosphere") the correct choice. The scientists do not disagree on the other three answer choices. The location of the event (choice F) and speed of the object (choice G) are given in the initial description, and the scientists don't disagree on the density of Earth's atmosphere (choice H). Once again, your familiarity with the content, in this case comets and asteroids, is not important. What is important is your ability to read two different points of view and quickly hone in on similarities and differences. Even if you knew nothing about comets or asteroids, it would be possible to get this question right by using critical reading skills. Here's a summary chart of the types of questions you'll see on ACT Science: Type of Question Skills Needed Number of Questions (Percent of Questions) Data Representation Read and understand data About 15 questions (35%) Research Summaries Interpret the design and results of experiments About 18 questions (50%) Conflicting Viewpoints Compare, contrast, and analyze opposing viewpoints About 7 questions (15%) Bottom Line If you can read and interpret graphs, charts, and tables, analyze differing opinions, and understand the scientific method and study design, you will do well on ACT Science. This section tests your scientific skills, not your knowledge of scientific facts. As you practice for this section, focus on how well you are able to quickly read and understand data and experiments. Also make sure you are able to compare different viewpoints and find similarities and differences. Doing specific ACT preparation and using practice questions will help you see if your scientific reasoning skills are strong enough to do well on this section. What’s Next?

Panic Disorder - Psychology Essay Example | Topics and Well Written Essays - 3000 words

Panic Disorder - Psychology - Essay Example Taking into consideration the fact that functions such as consciousness, circulation, and respiration are vital for survival, it is unsurprising that particular defenseless people will be hypersensitive to any signs that they will lose consciousness, that they will lose their breath, or that their hearts will stop beating (Root, 2000). Moreover, a number of patients are predominantly terrified of symptoms that signify that they could be losing control over vicious urges directed toward others or themselves (Stein & Hollander, 2002). Likewise, a number of patients are particularly responsive to indications of behavioral or psychological ‘dyscontrol’ due to the probable effects of being hospitalized for ‘wild’ or ‘mad’ behavior, or perhaps shamed for uninhibited behavior (Stein & Hollander, 2002). The patient’s anxiety that a critical organ, such as the brain, lungs, or heart, or behavioral mechanism is about to stop working is a fundamenta l element of the cognitive mechanism of panic disorder (Taylor, 2004). Due to these concerns, patients vulnerable to panic attacks have a tendency to focus their attention on any mental or bodily encounters that are not explainable as normal. A second attribute of panic disorder that challenges clinician and offers a profitable opportunity for the psychologist is the fixation of attention on the idea of an imminent tragedy. The tragedy that they fear subsequent to the start of the attack is not just the development of the panic disorder, but the likelihood of the much serious different explanation of their symptoms; specifically, that at this point it may not be the ordinary panic, but a swiftly grave process or a severe disruption of behavioral or mental functioning (Hurley, 2007). Besides the fixation on inner consciousness, the idea of approaching disaster absorbs the core of the patient’s thoughts and is usually so realistic that the

Why you chose the qualitative versus quantitative approach Assignment

Why you chose the qualitative versus quantitative approach - Assignment Example Hence, qualitative researches have proven to be used widely in GI nurses field. Nursing is primarily interpretive. Nurses have an interest in the daily health experiences with their patients, and much qualitative research makes nurses think about their practice (Sandelowski et al. 2012). Patients have diverse perceptions of an issue that do not always fit into numerical quantitative research approaches. The qualitative approach allows nurses to review previous findings of an issue because the method does not have rigid formula and calculations like the quantitative approach. Qualitative analysis is better set to provide information about the meaning of a disease of patients and the way it has affected their life. It is rich in providing personal information and experiences through the interviews. Nursing is a field of practice that borrows much of its information and knowledge from other diverse fields like medicine and psychology (Leeman and Sandelowski, 2012). The research analysis method adopted thus should depend on knowing the experiences of the participants through getting their views. A qualitative approach is interpretive and inductive and can create knowledge about human health and the disease experience of a participant. Qualitative knowledge and information depend on data on the social context with the main aspect being the comprehension of human experiences. It is thus the most befitting approach for the nursing practice, as opposed to the quantitative research method. It ensures a unique perspective of the study question or issue and it always gives a deep insight into human beings when compared to quantitative analysis, which is an essential aspect of the nursing practice (Sandelowski and Leeman,

Analysis - Case Study Example In the e-learning project, strong team work made it to attain its objective making the Australian Customs Service to provide excellent services. Being a body that is responsible for provision of security and integrity of Australia borders, Australian Customs Service noted the need to develop a system that would ensure effective collaboration among the 4,900 employees (David, 2006).The e-learning project was undertaken after the Customs evaluation and came to a conclusion that it will achieve the expected outcomes. One of the notable strengths of the project is that it enjoys the support of the large number of employees. In this way, it would not face resistance during implementation. Additionally, Australian Customs Service applied new technology that is positively viewed as a major solution that faces security personnel. The project also underwent extensive analysis before being implemented, implying that minimal resources were lost resulting to a higher rate of return on investment. The strong working relationship between the project managers and the working group is another strength that made the e-learning project to achieve its objectives. Based on the need by the Customs to provide a project that is effective, the process of planning e-learning took a lot of time. The costs that the Customs underwent in terms time and financial resources could have been possible reduced by outsourcing the project. Due to the modern technology that the e-learning project is adopting, the Customs have an opportunity of conducting training programs easily. On their part, people working in Australian Customs Service will get a chance of enhancing their skills thus becoming more productive. The e-learning project can also be adopted by other security agents that work in collaboration with Australian Customs Service. In this way, the Customs work will not only

Home Energy Management System

Home Energy Management System 1) INTRODUCTION Network of electricity that intelligently integrates with users actions connected to network for sustainable, economical and secure supply is called smart grid [1]. Smart grid is called smart due to fast communication and networking capabilities. Smart grid has an important role in energy structure adjustment, coping with climate changes and economic development [2]. Since 1982 energy demand during peak hour is increasing 25% approximately every year [3]. New intelligent devices must be used to fulfill energy requirements. In order to add intelligence new technologies are to be developed. Electric intelligence is only requirement for operational cost and energy consumption reduction [4]. These new technologies should be able to remove peak load and off load power difference, should be capable of making demand-supply curve smoother and should reduce environmental pollution. In smart grid user plays a vital role in reducing and optimizing energy consumption thus improving system efficiency. In smart grid emission of CO2 and household energy consumption is reduced by 9% and 10% respectively [5] In order to improve electricity consumption keeping in view of consumer’s need there should be an optimum solution. Different optimization techniques can be used for energy management. Different technologies like home area networks, home automation, advanced metering infrastructure and bidirectional communication are introduced by smart grid during past few years [6]. Now a days Zigbee and sensor networks not only monitors the quality of power but use powerful strategy for communication and distribution and sale locally generated energy back to grid [7] [8]. Demand Side Management (DSM) system is important utilization efficiency parameters which have been ignored due to complex dynamics of consumption, random behavior of consumers and lack of commutation technology. The advancement in communication technology has revolutionized the power sector and introduced a concept of new modernized electrical system called as Smart grid [9] .The concept of demand side management was first introduced in late 1970’s which reduces GHG, provides reliable energy reducing the electricity cost [10]. Traditional grids consists of DSM but do not provide such type of reliability to users due lack of sensors and inefficient automation and communication. But smart grid is more efficient due introduction of low cost sensors, smart meters and integration of ICT [11]. Challenges faced by smart grid is shown below Interoperability is said to satisfy if multiple communication network coexist in smart grid. Scalability means increasing number of hardware’s in proportion to others but due to increase in demand this become a major issue can be solved by using sensing networks. Smart grid holds different communities and societies which become an issue in order to resolve it integration of power system is required which is done with actuation, security and communication networks. Security is main issue in smart grid because a hacker can interrupt the data of smart grid and easily access to smart meters so this issue can be resolve by modernization the security and by data hiding [12]. The smart grid consists of HEMS that enable demand response and demand side management. On the basis of power supply demand response is responsible for altering and managing the energy and demand side management (DSM) controls the planning, techniques and implementation of policies [13]. There are two major schemes of HEMS one is communication and 2nd one is optimization [14]. Home energy management systems consist of three basic functional blocks [15]: HEMS software Home energy management center(HEMC) Load scheduler. HEMC provides customer’s user’s friendly graphical representation which not only provides assistance to customers but also give them control over various loads using load scheduler. HEMC software uses lab view developer tool that provides necessary information to customers using Zigbee protocol. It has two main sectors a) home tab b) data tab. The information load control, line control and on/off control is provided by home tab on/off control use in switching sequence and its major application is that it is used to detect any abnormality in hardware. The data logging of current and voltage with in time is represented by data tab. Load scheduler considers the bundle of single knapsack known as multiple knapsacks due to which customers become aware of peak load at specific time and interval of occurrence. A load scheduler not only determines the critical and non-critical loads but also time dependent loads. In emergency conditions it also controls various loads. This also stores data of electricity consumption 24/7. Energy management is an organized and systematic coordination of procurement, conversion, distribution and use of energy to meet the requirements, taking into account environmental and economic objectives [16]. Energy management systems are computer aided tools that are used by operators of utility grid for controlling, monitoring and optimizing the generation and transmission system performance. In efficient energy consumption the participation of end user is as much important as the supplier. In modern power supply systems end users’ are provided with RT-feedback (real-time feedback) via different website portals, in-home displays (IHD), or some other feedback viewer device like mobile etc. [17]. Provision of feedback to end user will motivate them to alter their energy usage to minimize the electricity bills. In present smart grid system end users’ are forced for shifting their energy usage on peak to off peak hours regardless of their comfort and life style [17]. All over the world major portion of energy is consumed by residential users, so they can play an important role for energy optimization. Research shows that energy consumption is minimized by 12% by installing energy consumption information system and displays energy consumption of whole unit [18]. Due to advancement in technology the industries has become advance due to which energy demand increases which results in load shedding and blackouts and use of fossil fuel is increases which will finish soon. Now world is going toward non-conventional energy resources like solar and photovoltaic cells but in order to provide information regarding to electricity to customers the smart hems use analogue and digital systems which is an efficient methodology. Home energy management systems play a fantastic role in distribution of energy via conventional grid and homes optimistically. With increasing demand of energy the communication in wired as well as in wireless medium is increased. Internet connection and intranet connection is makes low cost smart homes. Zigbee is one of the devices that uses for communication between smart homes and smart grid. Zigbee alliance introduced Zigbee standard protocol based on IEEE 802.15.4 standard set by IEEE and new standard committee (NESCOM) for low rates wireless personal area network [15]. Zigbee consists of four layers. Zigbee Zigbee alliance platform IEEE 802.15.4 There is a great difference between energy production and consumption, low production cause deficiency of electricity supply. World energy production pie chart is shown as There are many optimization techniques that are used for optimization one of which is knapsack. In knapsack there are many algorithms used for obtaining the best optimized result. In this paper we will make comparative study of some algorithms of knapsack and we will find the best solution obtained from these algorithms. Comparison of different home energy management schemes: Optimization based residential energy management: It is the linear programming model basic purpose of this model is minimization of electricity cost at residential areas [1]. In this scheme a day of 24 hours is divided into equal time slots having equal lengths consists of various prices of electricity like time of use (TOU) tariffs. The objective function shows that with proper scheduling we can reduce the energy expenses by division of home appliances in time slots. Objective function is defined as EI DI Ut St Where I define number of appliances, E defines energy consumption of appliance, J number of days, DI length of cycle of appliance, K number of requests, Ut unit price for slot t and T number of time slots. IN home energy management (iHEM): This scheme use smart appliances like energy management unit (EMU) and wireless sensor home area network (WSHANs) for communication purposes between appliances (IHEMS). It also uses (Zigbee) protocol, wireless sensor networks and cluster tree topology. In this scheme customer may turn on appliance at any moment without being worried about peak hours. In home energy management (iHEM) gives suitable time to customer for appliance use. How iHEM works a request package is sent by appliance to EMU at the start, on receiving the packet EMU communicates with storage system in order to know available energy. Energy management unit (EMU) than communicates with smart meter for current prices. The storage unit send available reply containing information about storage energy when EMU receives packet, it schedules the suitable start time according to iHEM algorithm. It also reduces the carbon emission and energy consumption cost. 2) KNAPSACK: The single knapsack is a problem of combinatorial optimization having objects, values and weights packed into knapsack of specific capacity such that value of object is maximized [19] .The multiple knapsack is generalization of single knapsack problem it is resource allocation problem consists of M resources and set of N objects [19]- [20]. Knapsack problem is basically an items set that have different weights and values. Our choice of item must be in such a way that it should be maximum among the weights of given items. Knapsack allows community to use energy efficiently in order to achieve their goals. It not only minimizes the customer bills but force them to use their heavy appliances other than peak hours. It is estimated that energy demands overall around the world increasing 25 percent per year so its great challenge for us to fulfill the demand [21]. In order to overcome the increasing demand of energy we need to optimize energy usage. Knapsack is one of the optimization technique used for optimizing a problem. 2.1) Types of Knapsack: There are different types of knapsack which are as 1) 0-1Knapsack problem. 2) Bounded Knapsack problem. 3) Unbounded Knapsack problem. 2.1.1) 0-1 Knapsack problem (binary Knapsack): In such case the item is either taken or not taken (accepted / rejected) there are no other possibilities. Suppose a set of ’n’ items having different weights and values say ‘wi’ and ‘vi’, xi is the number of copies of item of set ‘n’. In mathematical form: Maximize ixi Subject to i xi ≠¤ W Here Xi {0, 1} 2.1.2) Bounded Knapsack Problem: In bounded knapsack problem restriction on xi is removed i.e. xi is an integer value in BKP. In BKP restriction is applied on copies of each item of set ‘n’ to some integer value say ‘ci’. Mathematically: Maximize ixi Subject to i xi ≠¤ WHere xi {0, 1†¦ ci} 2.1.3) Unbounded Knapsack Problem: In unbounded knapsack problem no restriction is applied on xi. Mathematically: Maximize ixi Subject to i xi ≠¤ WHere xi ≠¥ 0. 2.2) Algorithms for Knapsack: There are many algorithms for solving 0-1 knapsack problems which are as [22]: 2.2.1) Brute Force: It is a straight forward approach based on statement of problem and concepts’ definition. If there are n items that can be chosen from a set of given items then there will be 2n possible combination of items for knapsack. There is a bit string of 0’s and 1’s, if the string is 1 of an item then it is chosen if 0 then not chosen. 2.2.2) Dynamic Programming: It is a technique in which a complex problem is divided into smaller sub problems. These sub-problems are then solved and are recorded in table. Thus table obtain is utilize to solve original problem. The complexity of this algorithm is O (NlogN). 2.2.3) Greedy Algorithm: This algorithm requires some common sense and problem solving experience for solving problem. It’s a decision making process which may have following steps: 1) Choosing such item that has maximum value in knapsack. 2) Choose item with less weight. 3) Choose item with high value to weight ratio. 2.2.4) Genetic Algorithm: It is an algorithm used to search best solution among different possible solution of a problem. It begins with a solution set and each set is called population. A new population is made from old population by selecting them according to certain specified fitness level. 3) Appliance Usage Control: In [23] consumption of electricity is not always rational it also depends on human psychology factors. Different people use different appliances at different time slots. Now if we consider some appliances we can classify them into following categories: 1) Must Run Appliances: Appliances whose time slot cannot be changed and they must run comes in this category. 2) Fixed Run Appliances: Appliances that run only once a day at specific time. 3) Flexible Appliances: Appliances that can be run at any time in a day they don’t have fixed time. Some of the household devices are shown below: Oven LampRefrigerator Fan Considering human psychology factor the use of appliances can be categorize as: 1) Emergency Use: Appliances that use in some sort of emergency. 2) Welfare: Appliances that use for welfare 3) Enjoyment: Appliances that use for enjoyment purpose. Taking an example of personnel computer that is used by student for his working purpose or for emergency while an adult use it for enjoyment purpose. In order to make decision on which appliance should be used during peak hour follows analytic hierarchy process. Bibliography

All public behavior is ultimately private behavior

Ever since Stephen Covey established himself with his phenomenal book The Seven Habits of highly Effective People, people are on the lookout for what is deemed quality reading that he had then became known for. In First Things First, it is expected that it is going to be a repeat of the success of the previous material (Covey et al. , 1994). People of today are mostly living in harried and often-times exhausted schedules.The pressure to juggle jobs, family and other jobs primarily due to financial needs is a common experience of people today and this has led to a number of complications both to the mental and physical existence of individuals, and the devastation of some of their precious relationships, that necessitate adjustments constantly. Covey refers to this as time management dilemmas and leadership problems (Covey et al. , 1994).This paper attempts to draw some important discussions and assumptions that relate to the book’s content and the authors’ understanding of how several principles are applied to address what makes a person effective ultimately in the public arena or workplace and in his personal life. Discussion It is inevitable that juggling work and family life will be one of a person’s demanding experiences. The rationale for having a job is not only to have a livelihood, achieve personal satisfaction in the expression of his abilities and trainings, and receive his remuneration and perks on the side.Preparation for family stability to be able to provide and thus create an atmosphere of care, for bachelors/maidens, is also the foremost and logical reason for having a job. However, the thin thread that separates between the two polarities becomes blurred, and there lies the tension that pulls a person in different directions (Covey et al. , 1994). The Center for Mediation and Dispute Resolution opens its website with the following quote: â€Å"Our life is one giant balancing act (http://www. cmdronline. com/workshops. htm) . † Perhaps, no person will ever disagree with that statement.The goal then is to know how to do the balancing act, to gain competencies in achieving a rewarding, flourishing kind of life that holds work in one hand, while maintaining a well-nurtured and healthy family on the other hand. The array of questions that confront couples or families with this dilemma is quite limitless. Stress is a psychological factor and a common feature of almost every kind of work (Covey et al. , 1994). Two reasons may be suggested why there is a growing recognition of the importance of stress on the job.First, there is the general awareness that stress-related diseases have reached epidemic proportions. More people die or are disabled today as a result of stress than at any other time. Because stress is so physically damaging and pervasive in people’s lives and because it is primarily psychological in nature the discipline of psychology as a whole and especially the specialty area of hea lth psychology is interested in studying and treating stress and other psychosomatic disorders (Covey et al. , 1994; Chang et al. , 2006). The second reason for the growing awareness of the importance of stress at work is practical.The effects of stress on the job are costly and are reflected in a lower productive efficiency. Stress has been known to reduce drastically employee motivation and the physical ability to perform the task well thus, increasing absenteeism, turnover, and tardiness (Covey et al. , 1994; Cahill, 2003; Chang et al. , 2006; Williams, 2003). The main assumption that this paper asserts therefore, is that given the impact of stress to people, it is expected that the average individual look for solutions to minimize its impact and certainly, Covey’s principles in time management is nothing else but timely.The importance of sorting through what is important and the urgent as illustrated in the four quadrants or time matrix is understandably logical, but dete rmining what’s what in somebody’s schedules and activities are then entirely different. People have to go through â€Å"painful† realizations of what activities should stay and what should go in accordance to established priorities. The latter, concerning priorities, the book â€Å"First things first,† took time to guide in making every reader understand.Overall, then, each person must confront and deal with a large and recurring number of stress-producing events everyday both at home and at work. Although most people experience at least some of the harmful effects of stress at one time or another, most people, fortunately, do manage to cope (Covey et al. , 1994; Landy, 1985; Williams, 2003). One effect of stress on the job resulting from overwork is called burnout. The employee becomes less energetic and less interested in the job.He or she becomes emotionally exhausted, apathetic, depressed, irritable, and bored; finds fault with everything about the wo rk (Cahill, 2003; Chang et al. , 2006; Landy, 1985; Williams, 2003). Employees with burnout become rigid about their work, following rules and procedures blindly and compulsively because they are too exhausted to be flexible or consider alternative solutions to a problem (Covey et al. , 1994; Landy, 1985; Williams, 2003). There is a price to pay for such overwork over a long period of time. Stress accumulates and leads to the psychological and physiological ailments described earlier.These people work so hard that they burn away their energy faster than the body can replace it. Such persons have been described as workaholics, or employees addicted to work (Cahill, 2003; Landy, 1985; Williams, 2003). There is no person existing who may not possibly experience inefficiency and ineffectiveness (as the book implies); by-products of this highly stressed culture as a result off wrong choices of what is really deemed important. The urgent takes control of the important matters that renders a person conducting unhealthy and often destructive lives (Covey et al., 1994). Conclusion Ultimately, people lead their lives in public as a result of personal choices or how they conducted their lives in private. The choices they make in life and work are best seen as results of private behavior; i. e. the important aspects of one’s life (the â€Å"compass† as Covey states it) (Covey et al. , 1994) takes precedence over the seemingly urgent yet unimportant activities. In general, people become satisfied and fulfilled when success comes to both important areas in his/her life.Work brings personal gratification and provision for family is secured somehow, while having a happy and contented family is considered miracle in a dog-eat-dog world. This is the aspiration of many if not all working couples and individuals. When employed in an institution that really takes care of their workers, taking into consideration the things that their employees hold dear by providing a s much as the employee needs, the worker or employee settles into a condition wherein he/she can focus on the work or be inspired of it.In addition, the worker can afford more quality time to spend with his/her family. The strategies mentioned are time-and tested approaches. These have greatly helped a lot of people or families in their search for a balanced work-family life. At the stake when a family works to achieve a balance are principles or values they uphold (Covey et al. , 1994). These are the values of family togetherness, rearing and nurturing their offspring, and providing for all aspects of each household member.

Table 4. 1 Issues related link vendor selection Issue Consideration Multiple vendors in same radius Description Any vendor that already has a link running in nearby location should not be given priority. Try to provide the link to another vendor which has no or less links running in that area. Introducing multiple vendors will ensure maximum uptime for that area. Redundant backbone for Intercity Links Select vendors that have different backbone for intercity connectivity.This will increase uptime incase of intercity backbone fails. Shorter Last mile connectivity Try to select vendors that will be able to provide last mile connectivity with shorter cable distance. As longer cables suffer from higher down time and require more maintenance. Licensed Radio Frequency Tower Height for Radio Links This will ensure better service quality and uptime. Identify vendors that will be able to establish a radio link with shorter tower. One time installation charge increases as tower height increases. Longer tower needs more maintenance cost. Service QualityVendors with poor service quality should not be considered even though they have met all other requireme nts. Support Personnel Select vendors that have dedicated support personnel for remote locations. Also count response time for all previous downtime. Balance of Distribution In order to ensure maximum uptime it is important that we balance the distribution among the vendors. This will decrease the overall downtime. Local Loop Avoid same type of media for Last mile connectivity.

We can find our user bases IP, MAC, OS and connected switch port related information. Form which we can easily sort out day to day operations and support related works like IP allocation for user, for switch port rel ated MAC releasing where switch port security is deployed, real time bandwidth monitoring, and configuration file management related works. For OpUtils related operations need to login to http://10. 0. 0. 236:7080/ 31 Fig- 6. 1 OpUtils Login Page Log in with given username and password. The Home page shows the summary report of the switch port and IP availability. Fig- 6. 2 OpUtils Home Page (Summary Report) 32 6. 3. 1 Switch Port Mapper It contains switches information and the users connected switch port information tagged with its IP address information. In Switch Port Mapper portion Fig- 6. 3 Switch Port Mapper portion Go to switches to see the list of the switches Fig- 6. 4 List of Switches 33 Go to Routers to see the list of the routers Fig- 6. 5 List of RoutersSummary will show the detail switch information of the network Fig- 6. 6 Switch information summary 34 To find any MAC address we need to select the MAC address options from the search tool box and write the MAC in colon (ff:ff:ff:ff:ff:ff) format to get the total IP related information and the connected switch address. Fig- 6. 7 Finding a MAC address 6. 3. 2 IP Address Manager In IP address manager restrain IP related information where we can allocate the IP with specific user information. The IP segregated into three different types: i. ii. Used IP: Currently using IP addresses.Transient IP: was used but is not using for couple of days and the system store the IP in this mode for 30 days and after that system will automatically make it as a Available IP iii. Available IP: free IP’s are known as Available IP Address. 35 In the left side of the window we can see the group’s name from where we can select the specific IP subnet. Fig- 6. 8 IP Address Manager Fig- 6. 9 IP Address Manager (Continuous) 36 Fig- 6. 10 IP Address Manager (Continuous) In the same way as shown in the Switch Port Mapper section we can search a user based on the IP address or MAC address.

SWIFT also markets software and services to financial institutions, much of it for use on the SWIFTNet Network, and ISO 9362 bank identifier codes (BICs) are popularly known as â€Å"SWIFT codes†.The majority of international interbank messages use the SWIFT network. As of September 2010, SWIFT linked more than 9,000 financial institutions in 209 countries and territories, who were exchanging an average of over 15 million messages per day. SWIFT transports financial messages in a highly secure way, but does not hold accounts for its members and does not perform any form of clearing or settlement. SWIFT does not facilitate funds transfer, rather, it sends payment orders, which must be settled via correspondent accounts that the institutions have with each other.Each financial institution, to exchange banking transactions, must have a b anking relationship by either being a bank or affiliating itself with one (or more) so as to enjoy those particular business features. 66 8. 2. 1 BRAC Bank Swift Network Diagram Fig-8. 37 Swift Network Diagram 8. 2. 2 SWIFT Infrastructure Overview: A typical SWIFT customer environment consists of a combination of individual components that interact with each other to provide messaging services. Fig-8. 38 Swift Infrastructure 67 Table 8. 3: Terms and description of SWIFT Terms FIN CBT SNL RA MQ HSM HTTPS Vendor product VPN box PKIDescription Software product that processes and that exchanges FIN messages, by using the FIN application through the SWIFT network. Alliance Access and Alliance Entry are FIN CBT products that are provided by SWIFT. As of now, these CBT products also offer the functionality to send messages for your Solutions through the Alliance Messenger interface. SWIFTNet Link. Mandatory SWIFT software component that is required in order to connect to SWIFTNet. Remote A PI. SWIFT middleware component that is used in order to link back-end applications and workstations to Alliance Gateway, which acts as the messaging concentrator.Message Queue. IBM middleware component that is used in order to link back-end applications through the Alliance Gateway. Hardware Security Module. A hardware device that is tamper-resistant and that ensures the secure storage and the processing of PKI secrets. HSMs replace the current Secure Card Rearders and the ICCs. There are three types of HSM devices: HSM boxes, HSM tokens, and HSM cards and card readers. Only one type of HSM is supported on the same SWIFTNet Link. Secure Hypertext Transport Protocol. A protocol that is used in order to access web servers that are hosted on SWIFTNet.The HTTPS proxy, which is a part of Alliance Gateway, is used for routing purposes. Product that is offered by a SWIFT partner and that allows to connect to additional services hosted on SWIFTNet. These products have an embedded SWIFTNet L ink, or they connect to Alliance Gateway. Virtual Private Network hardware device. Mandatory SWIFT network component for the connectivity to the multi-vendor secure IP network. A VPN box implements network security that is based on IPsec. Public Key Infrastructure certificate. SWIFT acts as the certification authority on SWIFTNet. 68 8. 2. 3 Maintaining the SWIFT environment: 8. 2. 3. 1 Daily activities ? ? ? ? ? Back up the system and the application data Monitor the systems and review the error logs Login to FIN to process messages that have been received Restart Alliance Access for database maintenance purposes, except if specific Arrangements have been made for continuous operation Export the RMA authorizations and distribute them to your other applications, if required 8. 2. 3. 2 Weekly activities ? Check the SWIFTNet Link connectivity after a weekend when maintenance activities are performed Check the connection to the HSM box by performing the SwHSMSelfTest command (This is a pplicable for HSM box configurations only) ? Archive the Alliance Gateway logs and journals Archive the messages and events of Alliance Access or Alliance Entry 8. 2. 3. 3 Monthly activities ? Restart SWIFTNet Link and Alliance Gateway, in order to ensure that the processes that use certificates are stopped. By performing this restart, the certificates can be renewed the next time that they are used to log on. 69 ? Open all the PKI certificates at least once. Use the CertInfo command or sign on the Web station or Web platform using these certificates, facilitating renewal and change of passwords. ? Back up all the PKI certificates after you have opened them. Use the SNL_BackUp. l command. (Note: This will back up all the certificates that are stored on disk. It will not back up the certificates that are stored in the HSM) Half 8. 2. 3. 4 Yearly activities ? Reboot all your HSM boxes but not together. (Applicable in HSM box scenarios only) CHAPTER NINE MAINTENANCE, MONITORING & SUPPO RT 9. 1 Overview BRAC Bank uses some software to monitoring, support and troubleshooting purpose.

Working with a leading business organization was a rare chance for me. I really appreciate the way I have been guided through this internship program with BRAC BANK LIMITED. Beginning from the opportunity to tak e the time I needed to refresh and expand my knowledge in several issues concerning System Administration. Over a somehow protected period where I could discover and learn to value my new working environment, and finally earned the confidence to deal with assignments myself. It is through them that I did enjoy my work every day.Having a rare opportunity to use the knowledge and skills that I had acquired, I learned how to handle critical network problems and got the new ideas. It was a great experience to work with networking devices practically and to troubleshoot different problems.
