Most industrial accidents occur when the workers' unsafe behavior and the unsafe situation of workplace take place at the same time. Although human's unsafe behavior is indispensable to work field, the evaluation scheme to detect the causes for the accident resulted from human's unsafe behavior and counterplan should be prepared to prevent and reduce accident. To do this, we first classify the specific background factors in terms of human inner factor and environment factor and then develop the AHP (Analytic Hierarchy Process) model to analyze the background factors that affect the worker's unsafe behavior. We also develop a checklist to be able to evaluate the occurrence possibility of individual worker's unsafe behavior.

야간 조명은 건강과 복지에 대한 인간의 욕구를 야간시간의 활용을 통하여 충족시킬 수 있도록 도와주고 있다. 또한 조명은 경관의 활성화와 미적 공간 창출의 유용한 도구로 이용되고 있어 근린공원에서의 조명은 주간과 다른 분위기를 제공하여 이용자들의 만족도를 높여주고 있다. 하지만 위험 요인을 가지고 있는 공원에서는 심미적 효과뿐만 아니라 이용자들의 보행 안전을 위한 야간 조명설계의 중요성이 강조된다. 본 연구는 야간 근린공원 이용자들의 보행 안전을 고려한 조명설계를 위하여 시뮬레이션 접근법을 이용하여 대안 조명품질을 비교한다. 기존에 설치된 조명기구와 타 조명기구를 시뮬레이션으로 비교함으로써 조명설계시 시뮬레이션 접근법의 유용성을 제안한다.

Cycling that transform human energy into mechanical energy is one of the man-machine systems out of sports fields. Benchmarking means " improving ourselves by learning from others ", therefore benchmarking toward dominant cyclist is necessary on field. the goals of this study were to provide important factors on multi-disciplines (kinematics, physiology, power, psychology) for a tailored-training program that is suitable to individual characteristics. Two cyclist participated in this study and gave consent to the experimental procedure. one was dominant cyclist (years:21 yrs, height:177 cm, mass:70 kg), and the other was non-dominant cyclist(years:21, height:176, mass:70). Kinematic data were recorded using six infrared cameras (240Hz) and QTM (software). Physiological data (VO2max, AT) were acquired according to graded exercising test with cycle ergometer and power with Wingate test used by Bar-Or et. al ( 1977) and to evaluate muscle function with Cybex. Psychological data were collected with competitive state anxiety inventory (CSAI-2) that were devised by Martens et. al (1990) and with athletes' self-management questionnaire (ASMQ) of Huh (2003). It appears that the dominant's CV(coefficient of variability) was higher than non-dominant's CV in Sports Biomechanics domain, that the dominant's values for all factors ware higher than non-dominant's values in physical, and physiological domain, and their values between cognitive anxiety and somatic anxiety were contrary to each other in psychology. Further research on multi-disciplines may lead to the development of tailored-optimal training programs applicable with key factors to enhance athletic performance by means of research including athlete, coach and parents.

To investigate acute drug intoxication trends in the elderly visited Emergency Medical Centers, Data was collected from the records of poisoning patients visited Five different Hospitals from January 1. 2007 to December 31. 2007. The analysis was conducted by using 135 cases of 624 cases. When considering only the elderly and making comparisons between the urban areas and the rural areas the following data was produced. In regard to patients with acute drug intoxication, the main substance of choice was pesticides. Cases of acute drug intoxication are definitely higher for those categorized as the rural elderly (75.0%) when compared with those categorized as the urban elderly (44.1%). The male to female ratio, those living together as a family, past suicide attempts, mental state and sobriety condition when they came, monthly distribution etc. between the two groups did not demonstrate a difference between them. In regard to reasons given for acute drug intoxication, suicide was the highest at 60.7% of the cases. When comparing accidental reasons for poisoning, the urban elderly, at 34.2% of their cases, were higher than in the rural elderly, at 23.7%. After first aid was administered, the admission rate was higher for the rural elderly (47.4%) than for the urban elderly (33.9%). This shows that the rural elderly have a more severe acute drug intoxication poisoning problem than the urban elderly do.

In business aspects, the corporate usually confronted with various risks. such as the management problems of the quality, the environment, the safety & health, the ethics, and the social responsibility. Overall monitoring of these aspects is required to the top manager ceaselessly. In the past ways, for these problems, the government has been controlled the corporate to keep them. But nowadays, the needs of self management of these topics is rising up for the business continuity especially to the multi-national corporate. To prove their soundness they issued the management status report periodically. Internal audit will works not only the self confirming tool but also the best supporting tool for the policy managements in such circumstances. So, an effective internal audit will lead the business continuity management to the future.

In these OECD countries, left-wingers Government focus on unemployment, but right-wingers Government cares more about inflation. It is that inflation and unemployment don't have differential effects across rich and poor and the happiness levels of these two groups are unaffected by identity of the Government in power. The poor people choose to left-wingers Government, but rich people prefer to right-wingers Government. I estimate whether above opinion is correct or not. Especially I check how my results change when I control for aggregate economy activity and government consumption, two variables that could be correlated with inflation and unemployment and affect each Government's happiness differentially. This paper, and I believe much of the happiness literature, can be understood as an application of experienced utility, a conception that emphasis the pleasures derived from private consumption and sentiment of it. In Granger Causality test, private consumption sentiment index related with industrial production interactively in Korea. The business cycles affect on private consumption sentiment index.

교량공사는 지상작업과 고소작업이 혼재하고 작업공종이 복잡하여 위험성이 높은 공사로 추락, 협착, 붕괴, 낙하 비래 재해의 발생빈도가 높다. 또한, 중량 부재의 운반, 조립, 양중 등의 작업과정에서 유해 위험 기계기구와 건설장비 사용에 따른 유해 위험 요인이 산재하여, 유해 위험의 정도와 재해 발생빈도 및 재해의 강도에 차이가 있어 위험성평가를 통한 정량화된 위험지수의 제시가 필요하다. 위험성 평가는 교량공사의 특성을 고려하여 교량 건설현장의 공종별 유해 위험요인을 세부공종별 요소작업에 따라 분류하고, 재해 발생정도와 피해정도에 따른 위험도가 평가되어야 한다. 이러한 교량 건설공사의 재해를 줄이는데 기여할 수 있도록 정량화된 교량공사 위험지수를 제시함으로써 체계적이고 효율적인 재해예방 활동에 필요한 기초자료를 제공할 것이다. 특히 교량공사 시공 상의 제반 위험요인을 사전에 점검하여 변경 보완 제거할 수 있는 재해 예방대책을 수립하여 재해를 최소화하는 연구가 필요하게 되었다. 건설현장에서 위험지수의 고저에 따라 자원을 적정하게 배분한다면 안전관리의 효율성이 제고되고, 궁극적으로 건설재해 감소에 기여하게 될 것으로 기대된다.

A railroad has a benefit of the mass transportation of a passenger and cargo, but just a time of accident could cause a huge loss of a human life and property. Especially, a typhoon and a localized torrential downpour usually happened in summer season have caused average 38.29 times of the missing roadbed which support the railroad in recent 7 years. If a train would pass on this railroad which the roadbed was missed, there could be a huge accident and many people will die. But, the security issue is not satisfied because the method of sensing the missing roadbed is depending solely on the naked eye inspection by a person in charge. So, in this study, I would like to suggest the missing roadbed real-time sensing and train operation system to reduce the possibility of the railroad accident by controlling the operation of train when the missing roadbed condition would be sensed in the real-time system.

The paper reviews gauge R&R studies by two-factor mixed models including random and fixed factors. The two-factor mixed models include restricted models and unrestricted models considering the interaction of two factors. This study also classifies the models according to the number of factors, and the combination of various factors such as random factor, fixed factor, block factor and repetition type.
