Three major Asian countries, Korea, China, and Japan, shared 18.3% of global GDP and 14.2% of global trade volume in 2005. When considering this number, cooperation of these three countries is very important. Also, it is needless to say that we need efficient international logistics system in Asia. The key point to realize efficient international logistics system is unit load system utilizing pallets and containers. To build up efficient logistics system among Korea, China, and Japan, we need 'total palletization' with standardized pallets. We may regard 'total palletization' as an 'efficient highway of North-Eastern Asia logistics.' In this study, we will suggest two kinds of effects, which logistics standardization among Korea, China, and Japan will make. One is the effect on economy and trade, and the other is the effect on logistics business and environments.

  The expected busy period for the controllable M/G/1 queueing model operating under the triadic policy is derived by using the pseudo probability density function which is totally different from the actual probability density function. In order to justif

The purpose of this study was to identify the influence of school foodservice dietitians' work value on job satisfaction, organizational commitment, and turnover intentions. Also, this study explored the role of the expectation to the institution of nutrition teachers as a moderating variable in three relationships: 1) between work value and job satisfaction, 2) between work value and organizational commitment, and 3) between work value and turnover intentions. This study surveyed dietitians who worked at school foodservice in Kyunggii and Daegu·Gyeoungbuk province. A total of 509 responses were collected using on-site survey and online survey (response rate 59.3%). This study conducted hierarchical regression analysis to test the moderating effect of the expectation to the institution of nutrition teachers. Results of hierarchical regression showed that work value of status upgrade had a positive effect on job satisfaction to promotion opportunity and salary, and such effect was more significantly apparent in high expectation to new work. In addition, work value of status upgrade had a positive effect on turnover intention, and such effect was more significantly apparent in low expectation to new work environment improvement. Work value of work activity preference also appeared to have a positive effect on organizational commitment, and such effect was more significantly apparent in high expectation to social status and professionalism.

The traditional process capability indices Cp, Cpk, Cpm, Cpm+ have been used to characterize process performance on the basis of univariate quality characteristics. Cp, Cpk consider the process variation, Cpm considers both the process variation and the p

In this paper we extend the classical decision model under uncertainty to a more general case. We propose an expected utility-uncertainty model and we can make a decision by trading off between a measure of uncertainty and a measure of expected value. As a risk analysis model, the expected utility-uncertainty model can be seen to be reasonable and flexible for states of nature or individuals' preferences. Moreover, the model can explain some decision paradoxes.

This paper is to propose tolerance intervals for expected time at the given reliability and confidence level for continuous and discrete reliability model. We consider guaranteed - coverage tolerance intervals, that is, reliability - confidence level tolerance intervals. These proposed methodologies can be applied to any industrial application where the customer's operating specification require a high level of reliability.

Process capability indices are widely used in industries and quality assurance system. When designing the parameter on the multiple quality characteristics, there has been a study for optimization of problems, but there has been few former study on the possible conflicting phenomena in considertion of the correlations among the characteristics. To solve the issue on the optimal design for multiple quality characteristics, the study propose the expected loss function with cross-product terms among the characteristics and derived range of the coefficients of terms. Therefore, the analysis have to be required a multivariate statistical technique. This paper introduces to multivariate capability indices and then selects a multivariate process capability index incorporated both the process variation and the process deviation from target among these indices under the multivariate normal distribution. We propose a new multivariate capability index MCpm using quality loss function instead of the process variation and this index is compared with the proposed indices when quality characteristics are independent and dependent of each other.

The purposes of this study were to a) find out the operational characteristics of the contract-managed highschool foodservice in Seoul, b) investigate the expected level of meal-price and facilities investment cost perceived by contract-managed highschool foodservice managers c) compare the present level and expected level of meal-price and facilities investment cost. From October 12 to November 13 in 2001, the questionnaires were mailed to 249 high schools which was managed by contract foodservice company with respondent rate 40.2%. Data were analyzed using SPSS Win(10.0) for descriptive analysis and one group paired t-test. The results of this study were as follows ; 1. The student enrollment of highschools run by contract-managed foodservice was 1,243 with 72.6% participation rate of school lunch program. The average meal-price was 2,138 won. The average annual period of school foodservice operation was 156.78 days per year. The average contracting period was about 3 years. 2. The average cost concerned in the facilities investment amounts 169,578,180 won at the initial investment and 25,204,092 won at the repairs and maintenance cost in the course of operation. 3. The present level of meal-price and facilities investment cost were respectively 2,136won/meal and 171,157,336.72 won. And expected level of meal-price and amount of facilities investment cost were 2,418.75 won and 121,353,215.19 won. Comparing the present level with the expected level of the meal- price and facilities investment cost, expected level of meal-price was significantly higher than the present level of meal-price(p<.001) and expected level of facilities investment cost was significantly lower than present level of facilities investment cost(p<.001).

This study is to select food offered with higher frequency at restaurants such as hamburger, pizza, chicken, gimbap(boiled rice rolled in laver with seasonings stuffed), and calgooksu(Korean traditional noodles); identify customers' expectation and satisfaction levels on food and service quality and analyze correlation according to each food. The survey was conducted from March 1 to March 24, 2000, by distributing questionnaires. Statistical data analysis was completed using SPSS for t-test, ANOVA, Pearson's correlation analysis. The results of this study were as follows: 1) It is revealed that overall average satisfaction levels on food quality according to individuals' trait came out significantly low compared to their expectation levels, and that balance in nutrition and reasonable prices had problems in relation to food quality. 2) Customers' expectation levels on food quality came out the highest with calgooksu and gimbap, and their satisfaction levels came out the highest with pizza. 3) Customers' overall average expectation levels on service quality showed a very high point, while their satisfaction levels showed a low point with significance. 4) Hamburger was poor in hygiene; pizza showed the highest satisfaction levels over its quality with significance, and calgooksu and gimbap showed very low satisfaction levels over their service quality. 5) Correlation between customers' expectation and satisfaction levels over the nutritional balance and proper taste of the food quality came out significant. 6) Pizza and chicken showed significant correlation with regard to atmosphere, service, and hygiene variables (p<0.01).

The effort to understand customer is essential and customer satisfaction measurement tool is needed in today's intensively competitive environment of restaurants. The objectives of this study were to measure customers' expectation and satisfaction of service quality attributes and to identify relatively important attributes for overall satisfaction in restaurants. The questionnaires were distributed to 232 customers at 78 family-style, pizza and fast food restaurants. Statistical data analysis was completed using SPSS for t-test, ANOVA, factor analysis, Pearson's correlation and regression analysis. The results of this study were as follows: 1) four and six- dimensional structures were established from 25 expectation and satisfaction attributes, respectively. 2) Demographic variables and usage characteristics didn't affect on service quality expectation, but expectations were significantly different according to the types of restaurant. 3) Expectation/satisfaction matrix showed different patterns in 3 types of restaurant. 4) 'Quality of food' and 'atmosphere' were the most relatively important attributes for overall satisfaction in restaurants.

이 연구는 대학 신입생을 대상으로 그들이 지각하는 역량과 학습기대에 따라 유사한 특성을 갖는 잠재집단이 도출되는지 탐색하고, 잠재집단 간 학습참여의 차이가 나타나는지를 확인하고자 수행되었다. 이를 위해 한국교육개발원의 대학생 교수학습 과정 조사(NASEL) 자료를 활용하여, 2019년에 광주 지역 S 대학에 입학한 남녀 신입생 497명을 분석대상으로 잠재프로파일분석을 실시하였다. 연구결과는 다음과 같다. 첫째, S대학의 신입생은 3개의 잠재집단이 도출되었으며 첫째 집단은 역량-학습기대 높은 집단, 둘째 집단은 역량-학습기대 보통 집단, 셋째 집단은 비인지적 역량-학습기대 낮은 집단으로 명명하였다. 둘째, 잠재집단 간 학습참여는 통계적으로 유의한 차이가 나타났다. 역량에 대한 지각과 학습기대가 높은 신입생 집단일수록 인지적 참여(능동적⋅협력 적 학습활동), 정서적 참여(수업만족도, 교육지원서비스만족도), 행동적 참여(수업참여, 교수/동료 와의 상호작용, 교육지원서비스 활용)가 높았으며, 특히 비인지적 역량과 학습기대가 낮은 신입생 집단은 학습참여가 모두 낮은 것으로 나타났다. 이러한 연구결과에 근거하여 대학 신입생의 학습 참여 신장을 위한 교육적 시사점을 논의하였다.

본 논문에서는 학교 영어교육의 중장기 발전 방향을 모색하기 위해 학교 영어교육의 실태와 기대에 대한 학생, 교사, 학부모의 인식을 설문조사를 통해 비교 제시하였다. 설문조사에는 학생 1,007명, 교사 144명, 학부모 340명이 참여하였으며, 주요 설문 내용으로는 학교급별 영어 수업시수, 최종 희망-예상 영어능력 목표, 학교 영어교육의 최종 목표, 현재 추진 중인 영어교육 정책에 대한 인식을 묻는 질문이 제시되었다. 각 설문 응답에 대한 결과는 기술통계 분석을 통해 경향성을 제시한 후 추론 통계를 실시하여 세 집단 간의 인식 차이의 유의성을 확인하였다. 분석결과는 다음과 같다. 첫째, 전반적으로 교사, 학부모들은 유사한 인식을 갖고 있었으나 학생은 다른 두 집단과 상이한 인식을 보였다. 특히 영어 수업 시수에 있어서 대다수의 학생들은 현재 영어 수업시수가 적절하다고 응답하였으나 교사와 학부모는 학생에 비해 영어 수업시수가 충분하지 않아 확대해야 한다는 비율이 상당히 높게 나타났다. 둘째, 학생, 교사, 학부모의 희망 대 예상 영어능력 목표 간 차이가 컸으며, 교사와 학부모는 학교 영어교육만을 통해서도 중급 이상의 영어능력 수준에 도달하게 될 것으로 기대했으나 학생들은 이보다 비교적 낮은 기대수준을 갖고 있었다. 셋째, 학교 영어교육의 궁극적인 목표로 세 집단은 각각 다른 응답 양태를 보였지만 일상생활에서 필요한 실용영어 능력 신장을 위한 영어교육을 우선순위에 두어야한다는 점에서는 동일한 의견을 나타냈다. 넷째, 영어교육 개선방안에 대한 응답으로는 ‘흥미와 자신감을 키워주는 수업 자료 보급’이나 ‘교과서 이외의 실제적 교수·학습 자료의 활용’와 같은 교수학습 자료개발 및 지원에 대한 필요성을 제기하였으며, 평가 관련 정책과 관련하여 ‘수업과 연계된 평가’ 또는 ‘과정중심 평가도구 개발’에 대한 높은 필요성을 인식하고 있었다. 마지막으로 설문 결과를 바탕으로 향후 초·중등학교의 영어교육의 내실화를 위한 정책적 시사점을 제시하였다.
