It is difficult to determine the static axle weight of a vehicle with weigh-in-motion systems which in absence measure instantaneous axle impact forces. The difficulty in determining a static axle weight results from dynamic effects induced by vehicle/road interactions. One method to improve the problem is to quantify a statistical confidence level for measured axle weight. The quarter-car model is used to simulate vehicle motion, Also, the road input to vehicle model can be characterized in statistical terms by PSD (power spectral density) of appropriate amplitude and frequency contents other than an exact spatial distribution. The confidence levels for the measured axle weight can be obtained by the random process analysis using both vehicle model and road input.

본 연구의 목적은 간호사들의 윤리적의사결정 자신감, 인성, 간호전문직관 및 도덕적 민감성 정도를 분석하고, 윤리적의사결정 자신감에 영향을 미치는 요인을 융합적으로 파악하는 것이다. 연구대상은 D, S시 소재 종합병원에 근무하는 간호사 174명으로, 연구 자료는 기술통계, t-test, ANOVA, Pearson's correlation and Multiple regression을 이용하여 분석하였다. 연구결과, 간호사들의 윤리적의사결정 자신감 정도는 중간정도이었으며, 인성, 간호전문직관, 도덕적 민감성과 유의한 양의 상관관계를 보였다. 윤리적의사결정 자신감에 영향을 주는 요인은 인성(${\beta}=.350$, p<.001), 간호전문직관(${\beta}=.172$, p<.001), 도덕적 민감성(${\beta}=.134$, p<.001)임을 확인하였고, 이들의 설명력은 25%이었다. 따라서 간호사의 윤리적의사결정 자신감 향상을 위해서 임상현장에서 인성, 간호전문직관 및 도덕적 민감성 향상을 위한 교육프로그램 개발이 필요하다.

Evaluating product quality level is necessary before the manufactured items are delivered to the customer. When the amount of the items to be manufactured is limited and the product is of high price and should be evaluated by destructive testing, the number of samples to be tested should be as small as possible. This paper presents a small-sample inspection method using hyper-geometric distribution and Bayesian approach for finite small-sized population. A method of determining the minimum sample size is presented for given population size, allowable number of defectives, warranteed defective level, and confidence level which is the degree of confidence on the product quality level recognized by both the producer and the customer.

The research interprets the principles of sampling error design for quality statistics models such as hypothesis test, interval estimation, control charts and acceptance sampling. Introducing the proper discussions of the design of significance level according to the use of hypothesis test, then it presents two methods to interpret significance by Neyman-Pearson and Fisher. Second point of the study proposes the design of confidence level for interval estimation by Bayesian confidence set, frequentist confidential set and fiducial interval. Third, the content also indicates the design of type I error and type II error considering both productivity and customer claim for control chart. Finally, the study reflects the design of producer's risk with operating charistictics curve, screening and switch rules for the purpose of purchasing and subcontraction.

Reliability demonstration tests with zero-failure acceptance criterion are most commonly used in the field of reliability application since they require fewer test samples and less test time compared to other test methods that guarantee the same reliability with a given confidence level. For products with lognormal lifetime distribution, an economic zero-failure test plan is developed that minimizes the total cost related to perform a life test to guarantee a specified reliability of a product with a given confidence level. A numerical example is provided to illustrate the use of the proposed test plan.

The present study aims to provide efficient regimen by means of the Oriental medicine tool to measure Yangseng developed to fit the situation of Korea. For this purpose, the elderly people aged older than 65 were selected and their level of Yangseng was compared and analyzed depending on their perception of health. From the study, following conclusions could be drawn: 1. The total subject of study were 763 consisting mostly of the illiterate and spoused with disease but without leisure activities. 2. Most of the subjects were found to have little confidence with their health. With regard to their level of Yangseng, higher points were rated in morality yangseng, followed by activities & rest, diet, mind yangseng, sleep, seasonal yangseng, exercise and sex life in order. 3. By socio-demographic characters for the group with confidence in health, there were more male than female, with spouse, disease and leisure activities currently. In the group without confidence in health, there were more female, without spouse and leisure activity but with disease presently. 4. As for the level of Yangseng in the group with confidence in health, higher points were recorded in morality yangseng, followed by activities & rest, mind yangseng, diet, sleep, exercise and sex life in order. In case of the group without confidence in health, higher points were recorded in morality yangseng, followed by activities & rest, diet, mind yangseng, sleep, exercise and sex life in order. From the above outcomes, it would be necessary to motivate the subjects to have a renewed concept for health and efficient regimen. Continued and repeated eforts should be made to fill the gap in the study using the tool to measure Yangseng of the elderly people.

본 연구는 운전확신수준을 구성하는 '상황둔감성', '불안전운전', '주의집중소홀', '운전자신감'이 교통사고에 미치는 영향을 살펴보았다. 총 1055명의 운전자를 대상으로 운전확신수준 질문지를 실시하였으며, 이들의 과속·음주 운전과 같은 위험한 운전행동 및 교통사고 경험을 조사하였다. 이 가운데 결측치를 확인하여 998명의 자료가 분석에 사용되었다. 그 결과, 운전확신수준의 구성요소가 교통사고에 이르는 경로를 통해 운전확신수준과 교통사고가 유의한 관련이 있음을 알 수 있었다. 운전확신수준 가운데 '상황둔감성'과 '불안전운전'이 교통사고에 유의한 영향을 미치고 있는 것으로 나타났는데 '상황둔감성'이 교통사고에 부적인 영향을 미치고 있는데 반해, '불안전운전'은 교통사고에 정적인 영향을 미치는 것으로 나타났다. 이러한 결과 운전확신수준을 구성하는 각각의 요인에 따라서 교통사고에 미치는 영향에 차이가 있음을 의미한다. 비록 본 연구에서 '주의집중소홀'과 '운전자신감'은 교통사고와 유의한 관계를 가지고 있음을 밝혀낼 수는 없었지만, 추후 이 두 요인이 운전에 어떤 영향을 미치는지 살펴보아야 할 것이다.

This study investigated the determinants of Tap Water consumption patterns. Socio-demographic variables(gender, family income, education level, residual area) and consumer attitude knowledge(confidence, knowledge, problem experience, risk perception and aesthetic satisfaction)were included in the analysis. Three hundred fifty-nine teachers were participated in this study. ANOVA(Scheffe test), t-test, regression and logistic regression were conducted. The results of this study are as follows: 1. Tap water was consumed by only 1.7%, boiled water prior to drinking by 37.9%, water filtered by 39.8% and bottled water by 19.0%. 2. Consumer attitude knowledge was affected by socio-demographic variables. That is, aesthetic satisfaction was affected by age, risk perception by gender and educational level, confidence by educational level, knowledge by gender and age, and problem experience by age. 3. Logistic regression analysis indicated that age, confidence and aesthetic satisfaction were the determinants of bottled water or filtered water choice. However, risk perception was not a significant determinant. This suggests alternatives to tap water is related to non-risk, or non-safety factors.

Purpose: The purpose of this study was to compare mother's caring-confidence, between primipara perception of the newborn, and child-rearing attitude and multipara. Method: The data was collected from 159 married mothers of newborns in the post-partum care center using self-rating questionnaires from November, 2003 to March, 2004. Data was analyzed using SPSS/Win program by t-test and Pearson Correlation coefficient. Result: 1) The mean score of mother's perception of the newborn, the newborn caring-confidence, and child-rearing attitude were .26, 3.13, and 3.43. 2) The score of the newborn caring-confidence of multipara was greater significantly than the one of primapara. 3) The score of mother's perception of tile newborn and child-rearing attitude of primapara were greater than the one of multipara but there were no significant differences. 4) There was a positive correlation between mother's perception of the newborn and child-rearing attitude and significant correlation between caring-confidence and child-rearing attitude. 5) The score of mother's perception of the newborn was significantly different according to the level of education type of family and delivery planned. 6) The score of caring-confidence was significantly different according to the helper, the history of delivery. 7) The score of child-rearing attitude was significantly difference according to the level of education and the birth weight of newborn. Conclusion: When the newborn care giver in the postpartum care setting is teaching the method of infant care to mother, there should be in consideration of the rearing experience of mothers. Mother's perception of the newborn, caring-confidence, and child-rearing attitude should be considered to develop the effective education program for mothers who have newborn. And its educational contents must be focused on the promotion of trust between infant and mother.
