...Background of the Study Sleep is a physiological need. It is a way to rest our body from fatigue. Hence, adequate sleep is a biological necessity, not a luxury, for the normal functioning of humans. Good mental and physical health depends on maintenance of adequate sleep. College experience is of great value in providing emerging adults with a structured environment in which they can gain knowledge, skills and independence to chart their own path, become successfully employed and contribute to society. For most students, the college environment is full of new living and social experiences, new freedom from parental supervision and new academic demands. In this situations, most often than not, adequate sleep is neglected. According to poll conducted by the National Sleep Foundation (2000) potential obstacle to maximizing success in college is the high prevalence of daytime sleepiness, sleep deprivation, sleep disturbances and irregular sleep schedules among college students. Daytime sleepiness is a major problem, exhibited by 50% of college students compared to 36% of adolescents and adults. At least 3 days a week, 60% of college students report that they are dragging, tired and sleepy. Sleep deprivation is defined as obtaining inadequate sleep to support adequate daytime alertness. How much sleep a young adult needs is known to be eight (8) hours. Most college students are sleep deprived, as 70.6% of students report obtaining less than 8 hours of sleep. Sleepiness is defined...

...relation, sleep patterns as in why do we need sleep, rhythms of sleep , sleep deprivation, sleep disorders, dreams and why do we dream. Sleep, as a human or animal we need to sleep because our body regenerates its self when it’s at rest. Humans spend at least one-third in an altered state of consciousness. When we are tired we crave to go to sleep just as if we are hungry we crave food. We can’t live without both. No human can stay p past twenty hours without feeling like they are about to crash. No one knows exactly why we need sleep but it plays and important part in restorative function. When humans are asleep there are rhythms of sleep. Circadian rhythm is a biological rhythm that last about 24 hours. There are 4 stages the sleeper enters when they fall asleep. Stage one is when the brain gives you the signal your muscles to relax. It also gives off that your heart is to beat slower and when that happens your temperature begins to drop. Stage 2 is a light sleep. You’re not fully asleep but you can be awakening. Stage 3 you are in a deeper sleep. Your blood pressure begins to get lower because your brain gives off that message. Even though the body temperature is getting lower the human that is asleep won’t notice. In this stage you can be woken but it won’t be as easy. Stage 4 the human is in a deepest sleep. If someone tried to waken this sleeper it would be very hard. If the sleeper awakens they will be very confused for a few minutes. Some may sleep walk or...

Siffre (1975) * Case study of his own experiences in an underground cave for 2 months. Without any exogenous zeitgebers such as light or cues to guide him, his sleep/wake cycle generally adjusted to a 25 hour cycle, though sometimes changing dramatically up to 48 hours. Aschoff and Weaver (1976) * Designed a temporal isolation study by placing participants in an underground ww2 bunker without an environmental or time cues. * They found that the free running cycle persisted with a sleep wake cycle of 25 hours, sometimes increasing to 29.

The Institute of Medicine of the National Academies reveals this, “Chronic pain affects about 100 million American adults—more than the total affected by heart disease, cancer, and diabetes combined.” No one around me recognizes my pain. I don’t have a wheelchair, a walker, a brace, or a cane. I’m not missing hair, I’m not old, and I don’t “look sick.” There is a problem with the people around me. It’s ignorance, it’s stupidity, and it’s needing an indicator that I’m in pain, without one I must not be. However, the biggest problem is when the people around me make assumptions about my...

...VICTIM RIGHTS ARE ALSO HUMAN RIGHTS ------------------------------------------------- Dr. Beulah Shekhar, Faculty, Department of Criminology & Criminal Justice, Manonmaniam Sundaranar University, Tirunelveli, The present system does not adequately focus on justice to the victims. The formal criminal justice system directs its attention primarily toward the offender, first with regard to guilt or innocence and second with regard to appropriate punishment, treatment, or monitoring. The informal justice system is often an abstract and distant concern. So, the victims have been repeatedly neglected as stakeholders in both formal and informal justice approaches, it is important to give special attention to their role in the criminal justice system. Presenting the report to Deputy Prime Minister L.K.Advani, who held the home portfolio. Malimath said the changes were proposed for the first time in 150 years. He also recommended that from now on, criminal laws be reviewed every 15 years so that they are in tune with the “changing times”. The “Criminal justice system is virtually collapsing under its own weight as it is slow, inefficient and ineffective” due to which “people are losing confidence in the system”, the report said. The present system of the prosecution have to prove the guilt of an accused “places a very unreasonable burden on the prosecution”, the committee said in its report and recommended that in India, like in the continental countries...

In common with most other complex technical activities, human error is implicated in the majority of aviation-maintenance-related quality lapses, incidents, and accidents. General estimates of this human error contribution have increased over the years, from a low of around 20% in the 1960s to values in excess of 80% in the 1990s. Human error in aviation is somewhat of a sensitive topic due to the recent tragic events of September 11, 2001. The goal of this research is to understand human error in aviation, in order to understand how designing better computer systems can assist in making the aviation industry safer for pilots and passengers, by reducing human error. This paper does not attempt to address accidents caused by cowardly acts of terrorism. Many people do not know that on February 20, 1981 a modern Argentine jet airliner, with 58 people on board, almost crashed...

...Advance concept of nursing I Unit 1 Nursing process The nursing process is an organized sequence of problem solving steps used to identify and to manage the health problems of clients .The nursing process is the framework for nursing care in all health care settings.When nursing practice follows the nursing process, clients receive quality care in minimal time with maximal efficiency. The steps of nursing process 1)Assesment 2)Diagnosis 3)Planning 4)Implementation 5)Evaluation Assessment An RN uses a systematic, dynamic way to collect and analyze data about a client, the first step in delivering nursing care. Assessment includes not only physiological data, but also psychological, sociocultural, spiritual, economic, and life-style factors as well. For example, a nurse’s assessment of a hospitalized patient in pain includes not only the physical causes and manifestations of pain, but the patient’s response—an inability to get out of bed, refusal to eat, withdrawal from family members, anger directed at hospital staff, fear, or request for more pain mediation. Diagnosis The nursing diagnosis is the nurse’s clinical judgment about the client’s response to actual or potential health conditions or needs. The diagnosis reflects not only that the patient is in pain, but that the pain has caused other problems such as anxiety, poor nutrition, and conflict within the family, or has the potential to cause complications—for example, respiratory infection is a potential hazard...

There are three basic types of learning. They are habituation, classical conditioning, and instrumental conditioning. Imagine a worm. When the tide is in, it comes out. It has extensions from its head, getting particles from the outside. So it comes out of its hole to snatch these particles. It has one fear though: seagulls. The worm is delicious to them. They see him and they eat him. The worm has a detection system wired in though. When there is a shadow, he ducks. It is a hard-wired reflex. Sometimes, however, shadows don’t mean a darn, like on a cloudy day. If it doesn’t come out because of the shadows, it will get nothing done and starve to death. Therefore, if the shadows are too frequent, it will ignore them. There...

...(2007) 274 – 284 Altered sleep–wake cycles and physical performance in athletes Thomas Reilly ⁎, Ben Edwards Research Institute for Sport and Exercise Sciences, Liverpool John Moores University, Henry Cotton Campus, 15-21 Webster Street, Liverpool, L3 2ET, United Kingdom Received 14 August 2006; accepted 4 September 2006 Abstract Sleep–waking cycles are fundamental in human circadian rhythms and their disruption can have consequences for behaviour and performance. Such disturbances occur due to domestic or occupational schedules that do not permit normal sleep quotas, rapid travel across multiple meridians and extreme athletic and recreational endeavours where sleep is restricted or totally deprived. There are methodological issues in quantifying the physiological and performance consequences of alterations in the sleep–wake cycle if the effects on circadian rhythms are to be separated from the fatigue process. Individual requirements for sleep show large variations but chronic reduction in sleep can lead to immuno-suppression. There are still unanswered questions about the sleep needs of athletes, the role of ‘power naps’ and the potential for exercise in improving the quality of sleep. © 2006 Elsevier Inc.

...Kuo, Sullivan / AGGRESSION AND / July 2001 ENVIRONMENT AND BEHAVIOR VIOLENCE AGGRESSION AND VIOLENCE IN THE INNER CITY Effects of Environment via Mental Fatigue FRANCES E. KUO is an assistant professor at the University of Illinois, UrbanaChampaign. Her research examines effects of the environment on healthy human functioning in individuals, families, and communities. WILLIAM C. SULLIVAN is an associate professor at the University of Illinois, Urbana-Champaign. His research focuses on the psychological and social benefits of urban nature and citizen participation in environmental decision making. ABSTRACT: S. Kaplan suggested that one outcome of mental fatigue may be an increased propensity for outbursts of anger and even violence. If so, contact with nature, which appears to mitigate mental fatigue, may reduce aggression and violence. This study investigated that possibility in a setting and population with relatively high rates of aggression: inner-city urban public housing residents. Levels of aggression were compared for 145 urban public housing residents randomly assigned to buildings with varying levels of nearby nature (trees and grass). Attentional functioning was assessed as an index of mental fatigue. Residents living in relatively barren buildings reported more aggression and violence than did their counterparts in greener buildings. Moreover, levels of mental fatigue were higher in barren buildings, and aggression accompanied mental fatigue. Tests for the...
