The aims of this study are as follows; first, to find out the difference between successful skier group and the unsuccessful group by comparing and analyzing the skating technique action of cross-country skiers who use V1 skating technique in uphill slope. Second, to present effective skating motion through analyzing various kinematic variables, such as trunk angle, arm angle, knee angle, ski pole, ski angle, in uphill course. The subjects of this study are made of two successful male skiers of national level and three unsuccessful male skiers of nonnational level. The motion performed by subjects were recorded using two video cameras at the speed of 60 fields per second, and analyzed using the DLT(Direct Linear Transformation) method of three dimentional cinematography. The conclusions are as follows; 1. In order to increase the skating velocity, it is needed to lift waist near vertically when begin poling, and stoop the upper body forward when gliding, out of consideration that the successful group has the wider motion scope of trunk angle than the unsuccessful group. 2. To increase a propulsive force, hands has to be held out to the motion direction, and ski poles are needed to be planted on the snow leaning to the body center direction. 3. For a strong skating force, it is necessary that knees, which have an effect on the cycle length, are bent much at the beginning of skating phases. And then, at the end of skating phases, it is needed to straighten the knees full to the outside of snow, and then to kick. 4. As for ski angle, skiers has to provide a strong propulsive force to the gliding ski, by kicking to side, decreasing the ski angle concerning course direction.

The statistical analysis methods utilized for analyzing the collected data are frequency analysis. χ² test. The conclusion obtained form these analyses are as following ; 1. In question about necessary optimum number of persons for rescue first, aid activity, health and non-health major college students responded by 39.2%, 45.3% respectively that rescue team 15 people, first aid team 3 people is most suitable. But there was no significant difference in major department(p< 0.05). 2. In question about security of the public health doctor and the emergency medical technician, all health and non-health major college students are recognizing necessity urgently, but there was no significant difference in major department(p< 0.05). 3. In question about 119 rescue·first aid team member applying for an examination qualification grant to the department of EMT's graduate, all health and non-health major college students were highest by 52.9%, 52.4% respectively in "necessity" item. But there was no significant difference in major department(p< 0.05). 4. Because rescue·first and equipment level appears higher than 41.7% in non health major college student's case by 54.2% in health major college student's case, health major college students are recognizing that equipment level should be supplemented more, but there was no significant difference in major department(p< 0.05). 5. In question about equipment supplement, all health and non-health major college students appeared highest by 64.8%, 69.3% in accident type different special equipment. But there was no significant difference in major department(p< 0.05). 6. In question about rescue·ambulance car size, we could know being thinking that health and non-health major college student each 61.2%, 56.5% is small and narrow that large size of the rescue·ambulance amount need. But there was no significant difference in major department(P< 0.05). 7. In question about patient's state is worsened, because rescue·first aid equipment is inferior, health major college student responded sometimes 55.1%, many 29.5%, very many by 11.5%, while non-health major college student responded 65.8%, 23.1%, 4.0% respectively. There was significant difference in major department(p<0.05) 8. In question about emergency patient must utilize for 119 rescue·ambulance car, all health and non-health major college students appeared highest by 38.8%, 41.3% in "not so" item. In question about rescue·first aid teams' first-aid treatment ability improves more, all health and non-health major college students appeared highest by 58.1% and 58.7% respectively in "improve" item. In question about "119 rescue·ambulance car must go more rapidly than now", all health and non-health major college students are recognizing that should be quicker by 58.1%, 60.9% respectively. When called to 119, all health and non-health major college students responded highest by 55.5%, 53.3% respectively that we must receive first-aid treatment direction from a doctor. In question about "119 rescue·ambulance car must be made the pay system", all health and non-health major college students responded 74%, 80% respectively in "not so" item. There was significant difference in major department(p<0.05). In conclusions, In oder to provide superior rescue·first aid service to people, a public health doctor should be placed in the situation room inside the fire station so that the doctor could instruct the proper emergency treatment suitable for each situation to the rescue·first and team. Also, national education about a first-aid treatment that do to all people is necessarily necessary in emergency delivery system and this should be spread extensively through school education and broadcasting medium and education should be hone side by side, and see that will can save emergency patients' life which is more when these education consists continuously fixed period for public institution of policeman, fire officer etc, specially. And for reinforcement of patient transfer system, public organization must procure special ambulance car so that emergency patient receive first aid treatment while transfer.

The purpose of this study is, through the kinematic analysis of the instep kick motion, to provide scientific data for coaches and athletes related with soccer. The subjects of this study were selected twelve students of junior high school(skilled group:3, unskilled group:3). Five trials were sampled with two high speed video cameras for each subjects at 60fields/s, but only one was selected for analysis. The DLT method was used to obtain the 3-dimensional coordinates of the body landmarks. The recorded images was digitized with Kwon3D Motion Analysis Package (Version 2.1). The conclusions were as follows ; 1. The elapsed time of skilled group was longer phase 1 than phase 2. There is no significant difference between phase 1 and phase 2 to unskilled group. And the strides of the skilled group showed smaller than unskilled group. 2. The velocity displacement of skilled group showed effectively from thigh joint to shank joint, from shank joint to ankle joint. 3. To take more poweful kick, skilled group increased joint velocity of kicking leg. However, unskilled group increased the horizontal velocity of the center of gravity. 4. The angle of the upper parts of trunk of skilled group was smaller than unskilled group at the whole phase. Especially, skilled group maintained the angle of the upper parts of trunk from E2 to E3. Differently, angle of unskilled group was increased at phase 2. 5. The minimum value of knee joint angle of skilled group was 62.23±9.08, comparing with 67.20±6.10 of unskilled group. Which is significant factor that skilled group takes more powerful instep kick. 6. At the whole phase, the ankle joint angle of skilled group showed larger than unskilled group. Taking a smaller angle than unskilled group, skilled group resisted tendency of rising above the air.

This paper presents new compromise ALT plan which is applied to situations that true relationship between stress and parameters is not known exactly. The assumed failure distribution of this study is one of location-scale family, i. e., exponential, Weibull, and lognormal distributions which have been ones of the popular choices of failure distributions. The method of applying the stress is constant, and the censoring mechanism is Type I censoring. Compared with existing compromise plans under true simple linear model in terms of statistical efficiency, the efficiency of new compromise plan is better than the corresponding other compromise ones in most cases. For case when true model is quadratic, this plan can be used without any severe loss in statistical efficiency. The proposed new compromise ALT plan is illustrated with a numerical example and sensitivity analyses are conducted to study effects of pre-estimates of design parameters.

수명이 지수분포를 따를 때 정기검사 및 정시종결하에서 신뢰성 샘플링검사계획의 개발

서순근,김갑석 한국경영과학회 1996 한국경영과학회지 Vol.21 No.1

A Reliability Acceptance Sampling Plan(RASP) is developed for testing the exponential mean lifetime under the periodic(i. e., equally-spaced) inspection and Type I censoring. Under the periodic inspection, the exact sampling distribution of maximum likelihood(ML) estimator of mean can not be derived. Hence sample size and acceptance criterion are determined by the algorithm proposed on the basis of Monte Carlo simulation such that the producer's and consumer's risks are satisfied for given censoring time and number of inspections. In addition, the developed RASP is compared to other RASP's designed under the continuous inspection and under the periodic inspection in terms of sampling size, OC curve, and expected completion time, The effects for the RASP by the chosen inspection scheme are also discussed.
