This study is to investigate patient's choice of health care and the demand for Korean traditional medicine care in rural areas in 1995. It tried to evaluate the effect of out-of-pocket expenditure, travel time, and waiting time on improving care-seeking and substituting clinical medicine for pharmacy care and Korean traditional medicine care in rural areas. The statistical model of this study is conditional logit to estimate effects of choice-specific and individual-specific characteristics on the choice of type of services. This study used, as explanatory variables, average out-of-pocket payment, travel time, and waiting time of services required to use the services. The model was empirically tested using data from 1995 Korean National Health Survery. The results showed that rural Koreans responded to out-of pocket payment and travel time. Increases of out-of-pocket payment and travel time decreased the probability to choose care in rural Korea. Rural Koreans were more likely to seek care than others with low out-of-pocket payment and travel time. The probability of choosing Korean traditional medicine were higher among the members of the households with higher education level and older persons, while they were lower in the households with large family than others compared with the probabilities of choosing public health facilities. The result of this study implies that policy on use of health care in rural Korea can be focused in managing travel time and out-of-pocket payment.

The purpose of this study was to examine the differences in satisfaction of leisure life and quality of life using standardized evaluation tools developed by WHO. Resource availability when dining out was measured by objective index(time of dining out, dining out expense) and subjective index(perceived satisfaction with time of dining out and dining out expense). In this study, 500 questionnaires(male & female adults) located in Seoul and the metropolitan area were sampled by convenience sampling and gather in 433 sheets of questionnaire. Data was analyzed by frequency analysis, factor analysis, reliability analysis, correlation analysis and regression analysis using SPSS Win 12.0. As a result there was high positive correlation between time of dining out, dining out expense and perceived satisfaction with time of dining out and dining out expense. Moreover, dining out resources impact on leisure life satisfaction and quality of life. Leisure life satisfaction had fairly high effects on quality of life. Since there is an increase in leisure time the desire to improve quality of life while enjoying dining out as a part of leisure life is increasing and as various forms of consumption takes place, it suggests that segmentation of dining out market is necessary and marketing strategy should be established.

The purpose of this study is to find the difference of household/work characteristics, family life satisfaction, and work satisfaction between home-based workers and out-of-home workers. The data of this study was collected from 230 married womens(home-based worker : 103 cases out-of-home worker : 127 cases) living in seoul. The major findings of the study are as follows. 1) Home-based worker's consumption expenditure structure, wive's housework time, schedule flexibility and degree of interruption, work loads were significantly higher than out-of-home workers. 2) Home-based worker's average monthly wage of her own and work time were significantly lower than out-of-home jokers. 3) Home-based worker's child care satisfaction and time use satisfaction were significantly higher than out-of-home workers. Out-of-home worker's self-fulfillment satisfaction, satisfaction of relation with supervisor, job stability satisfaction, work time satisfaction was significantly higher than home-based workers.

Determining the total duration for a construction project is an integral part of project management in the construction industry. This is to ensure the project and all its associated activities can be carried out and completed within the time frame stipulated. There are several commonly used scheduling methods and techniques in project management, some of which involves manual calculation while others involve computer software. This paper looks into the various time determination methods, extracting out their differences and similarities. It also seeks to draw out the problems when determining time for projects, especially those encountered of case studies. Based on the results from the case studies, there were delays on certain projects even though time determination had been carried out rigorously prior to the commencement of the projects. This paper seeks to develop a time determination model, which incorporates risk management techniques into the calculations in order to improve the method for time estimation to minimize the chances of project delay.

This study examines the relationship between second language use outside of class and oral proficiency development. It first identifies out-of-class activities of international graduate students in the U.S. and the average time spent speaking English in those out-of-class activities. Interviews and student self-measurements of time spent speaking English each day were used to investigate the types and quantities of out-of-class activities. In addition, two sets of student oral proficiency test scores were collected. Correlation analysis is used to find out the relationship of the variables between the most salient out-of-class activities and oral proficiency gains. The findings indicate that second language use outside of class is important for international graduate students to improve their oral proficiency. This is especially true with regularized interaction such as talking at work and the average time spent speaking in English a day outside of class. This study suggests that learners of English in an ESL environment should be encouraged to take part in out-of-class activities in addition to English use in the classroom in order for them to improve their oral proficiency.

물동량의 증가로 인해 컨테이너 터미널의 혼잡도가 높아지고 있고 이에 따른 장치장 및 게이트에서의 반출입 차량의 대기시간이 큰 폭으로 길어지고 있어 차량 운용 및 항만 운영 비효율이 극심한 상태이다. 이러한 문제 해결을 위해 부산항의 경우, 항만 공사 및 터미널 측에서 반출입 차량 예약시스템(VBS), 터미널 차량 혼잡도 정보, 예상 작업 처리 시간 정보 등을 서비스하고 있지만 실제 대기시간과 상이한 경우가 있어 가시적인 효과는 여전히 미흡한 실정이다. 따라서 이러한 문제를 해결하기 위한 기초자료로써 본 연구에서는 부산 신항의 컨테이너반출입 정보를 활용하여 딥러닝 기반의 반출입 차량 평균 대기시간 예측 모형을 제시하였다. 실제 평균 대기시간과의 비교를 통해 예측률을 검증한 결과 제시한 예측 모형이 높은 예측률을 보이는 것을 확인하였다.

Purpose The purpose of this study is to identify and analyze the key factors influencing congestion in the in-out transportation at port container terminals, and to design of a predictive model for in-out congestion based on these analysis. This study focused on architecting a deep learning-based predictive model. Design/methodology/approach This study was conducted through the following methodology. First, hypotheses were established and data were analyzed to examine the impact of vessel schedules and external truck schedules on in-out transportation. Next, explored time series forecasting models to a design the architecture for deep learning-based predictive model. Findings According to the empirical analysis results, this study confirmed that vessel schedules significantly affect in-out transportation. Specifically, the volume of transportation increases as the vessel arrival/departure time and the cargo cutoff time approach. Additionally, significant congestion patterns in transportation volume depending on the day of the week and the time of day were observed.
