김남현,백남칠 대한의용생체공학회 1981 의공학회지 Vol.2 No.2
In this paper, the reaction time and the accuracy of saccade eye movement are measured by using random pulse and periodic pulse, random pulse step and periodic pulse step through the subject utilizing the infra-red method.

본 논문에서는 포아송 (Poisson) 분포에서의 모수 추정을 베이지안 (Bayesian) 입장에서 다루었다. 먼저 여러 가지 이산 분포에서의 베이지안 방법을 다룬 몇 개의 논문을 간단히 살펴보았고 포아송 샘플링 모형이 타당한 이원 분할표에서 대수 선형 모형 (log-linear model), 정규 사전 분포 (normal prior distribution), 사후 최빈값 (posterior model), E-M알고리즘 (E-M algorithm) 등을 이용하여 경험적 베이지안 방법으로 변수들의 효과를 추정하였다.

Some tests of the goodness of fit of the uniform distribution between 0 and 1 are presented. The powers of the tests under certain alternatives are examined. As a result, the statistic based on the difference between the order statistics and the modal value of them gives good powers. We also give modifications of the statistic without using the extensive tables of the critical points.

Recently it is strongly criticized that the current operational system of emergency vehicles are not proper enough to deal with a number of emergent accidents, and so it has not been able to rapidly and effectively rescue people in many dangerous situations. It is indicated that one of the main causes of the problem is inappropriate enforcement of road traffic regulations. Emergency vehicle operation management system needs improvement so that it can function as community security and public interests. The current s. 25 and s. 26 of the Road Traffic Act stipulate the priority passage rights of emergency vehicle and exceptions, but in order to improve the efficiency of the emergency operations it is required to include additional exceptions, such as removing the prohibition and limits of passage (s. 6), the passage of safety zones (s. 12[5]), permitting the passage of designated lanes and emergency vehicles which are wider than roads (including alteration of driving ways at no-alteration zones) (s.l3[2-4]), permitting crossing, u-turn and reversing(s.l6[l]), and excluding punishment for violating safe distance. As this privilege of emergency vehicles can be secured through giving ways by ordinary vehicles, only highly indispensable vehicles should be designated as emergency vehicles with strict inspections and examinations. Also it is important that an increasing number of quasi-emergency vehicles and the utilization of the vehicles beyond the limit of service use should be enforced rigorously.

The Korean National Police Agency focuses on training a police officer who could sacrifice themselves for his/her country and citizens with excellent problem solving skills. Especially, KNPA decided to extend the training period and convert training contents into problem solving centered learning in order to train an officer with good personality who could quick adapt to the real field after placement. The Cadet Training Program of RCMP in Canada could be a good role model for KNPA in pursuit of high-quality police training education. Cadets learn core values of the RCMP in training and CAPRA is used as model as a standard for Community Policing Problem Solving and last5ly the IMIM is also used as a framework by which RCMP officers assess and manage risk through justifiable and reasonable intervention. The Cadet Training Program at the RCMP Training Academy is receiving positive evaluations. In order to make Korean National Police Training Program successful, we need to focus on creating core values of KNPA that Korean citizens can trust and problem based learning method should be applied throughout improving of the training method, contents and environment.

Shapiro and Wilk (1972) developed a test for exponentiality with origin and scale unknown. The procedure consists of comparing the generalized least squares estimate of scale with the estimate of scale given by the sample variance. However the test statistic is inconsistent. Kim(2001) proposed a modified Shapiro-Wilk's test statistic based on the ratio of two asymptotically efficient estimates of scale. In this paper, we study the asymptotic behavior of the statistic using the approximation of the quantile process by a sequence of Brownian bridges and represent the limit null distribution as an integral of a Brownian bridge.
