Thermodynamic behavior of a composite system which is composed of two simple thermal subsystems with constant heat capacities is analyzed, and several thermodynamic phenomena are investigated. The changes of the states and the potential work of the composite system are shown as the interaction between the subsystems in the composite system. The potential work is defined as the possible maximum available work from the composite system, and it is a thermodynamic property of the composite system. The decrease of the potential work is the same as the available work output from the composite system in reversible processes. The dissipation of available work is directly connected to the generation of entropy. The concepts of exergy and internal energy can be explained as a special case of the potential work.

본 연구에서는 또하나의 새로운 서술방식을 제시하게 되는데, 먼저 에너지 이동현상으로서의 일중에서 가용일을 분리하고, 가역과정만이 가능한 세계 즉 가역세 계 안에서 측정과 산정이 가능하도록 열역학의 가장 중요한 물리량인 온도와 엔트로피, 열 등을, 가용일의 가측성을 이용하여 정의한 다음, 그러한 제한조건하에서 기존 열역 학의 기본 법칙들이 어떻게 표시되는가 살펴보고, 이것을 비가역과정에 확장하는 식의 순서에 따라 열역학의 기존원리들에 대한 서술을 재구성하고자 한다.

PURPOSES : This study analyzes the available working time at work-zone on the Expressway in accordance to the new capacity manual. METHODS : Sensitivity analysis on variables were conducted to calculate the adjusted capacity at work-zone based on previous researches. RESULTS : The main factors which affect available working time at the work-zone were its capacity, number of lanes, terrain and lane width. Other factors have minimal effect on the available working time. Based on the analysis, a calendar of lane closures was suggested. CONCLUSIONS : A series of studies concluded that the capacity at work-zone in the new capacity manual reduced to 76-82% of the existing manual. As such, the available working time decreased. Furthermore, the factors affecting the available working time needs to be considered when making a plan to rehabilitate the distressed pavement.

The purpose of this research was to find out attitudes toward work and leisure in later life and intention to move to senior community available to work among 50's in Pusan, Daegu, and Daejeon. The survey had been conducted in 414 respondents with questionnaire during May to June, 2003. Frequency, Crosstabs, T-test and ANOVA were obtained from the collected data using SPSS/WIN program. The results of this study were as follows. First, most respondents were preparing toward work in later life somewhat actively and the level of preparation differed by individual characteristics. Those who have higher level of education and subjective economic power were more active. The most preferred work item in later life were raising animals and plants, managing institution and training center and running shop. Those who have higher level of education and asset preferred managing institution and training center. Second, nearly three fourths of middle-aged have chosen leisure activities in consideration of later life and two thirds were preparing economically for leisure in later life. They have strong intention to participate in the leisure activity in later life and they also wanted to take part in various kinds of leisure activities. Those who have higher levels of education, subjective economic power, health and asset were more active in preparing leisure in later life. Third, over two thirds preferred to live and work in later life together with others rather than to live and work alone. Nearly half had intention to move to the senior community where work was available. The intention to move were differed by attitudes to work and leisure in later life. Those who were active in work and leisure in later life presented higher intention to move to senior community available work.

The purpose of this research was to find out relation between the attitudes toward work and leisure in later life and intention to move to senior community available to work among 50's in Seoul, Incheon, and Kyunggido. The same research questions would be revealed as the previous one done by Cho & Cho(2006). The data were the part of the survey collected from 556 respondents with questionnaire during November, 2002 by the Hong's research team(2004). The results of this study showed that most respondents were somewhat actively preparing toward work in later life and the level of preparation differed by the individual characteristics such as age, health and occupation. They preferred various work items specially managing facility center, raising animals and plants, and managing educating center, which were different from what current elderly workers were mainly involved in. Similarly to the work, most respondents cared for the kind of leisure activities to continue and saved money for the leisure expenses in later life. The better the economic conditions, the more actively prepared for leisure in later life. They were strongly expected to participate in public leisure facilities and programs for the elderly as a user, volunteer, and/or activist. Over two thirds of the respondents preferred to work and live together in later life and over two out of five had intention to move to the senior community available to work. The more active in work and/or leisure in later life, the higher intention to work together and/or to move to the community. Those results generally supported the previous research showed that the needs of work and leisure in later life would be increased and varied, therefor housing for the elderly should considered work space and program as well as leisure. The further study was suggested to focus on the potential and current residents in the sample case of the comprehensive welfare town for the elderly by local administration.

This study analyzes the effects of the three types of flexible work arrangements (part-time, flexitime, and reduced working hours for childcare) available in Korea on work-family conflict, facilitation, and job satisfaction for married working women ages 15-49. The study employs a panel analysis based on the first to the fourth data from the Korean Longitudinal Survey of Women & Families (KLoWF). The major results are as follows. First, the availability of part-time jobs and reduced working hours to facilitate childcare is significantly related to work-family conflict for married women. If a married woman is employed in a part-time position or if reduced working hours for childcare are available, the conflict within the family caused by the job is reduced. Second, none of the three types of flexible work arrangements have a statistically significant influence on work-family facilitation for married women. Third, the availability of reduced working hours for childcare has a positive effect on the job satisfaction of married women. In conclusion, flexible working hours for women who are raising children are the main factor in reducing the negative effect of a job on a woman's family life as they contribute to work and family compatibility.

During a typical construction project, a contractor nay often find that the time originally available or normally expected to perform its work has been severely reduced. To finish the project by the completion date, the contractor is forced to find a way to speed up the progress of its work to compensate for the reduction in available time. The most frequent initial reaction of contractors to this situation is to increase on-site manpower by working longer time (overtime), adding more workers (overmanning), or implementing shift work (shift work) to increase the rate of progress. The goals of this study were to investigate how these three methods affect labor productivity and to quantify their impact on labor productivity by analyzing real project data collected from sheet metal contractors and mechanical contractors in the US.

The objective of this thesis to Provide a better insight into the effect of the amount of in-process storage has on the efficiency of production line with variable operation times. It is assumed that the material enters the line at the first work station and is then processed progressively through the line until it exits at the last work station, a finite amount of in-process storage is provided before all but the first work station of the line and the operation time of the work stations are statistically independent and follow exponential distribution. Under the above assumption, optimum allocation model is developed and following two approaches are used : 1) Given the available storage capacity, optimum allocation which minimizes the number of items in the line. 2) Given the available storage capacity, optimum allocation which. maximizes the utilization factor of the line. In a balanced three stage line, the production line efficiency is maximized under both categories when the second in-process storage is larger than the first.

Purpose: This paper explores diverse issues related to the problem of women's unpaid domestic care work, and as a factor of gender inequality in their professional practice. Research Design: This article concentrated only on the analysis of secondary data available on the topic along with observation of facts in Kazakhstan based on diverse sources. In current conditions, the problem of women's unpaid domestic care work, and consequently, the lack of enough time and energy for professional employment. Distinguish domestic work vs. job/career/occupation, self-fulfillment, education, and leisure has a significant impact on women's life satisfaction. Data, and Methodology: This article focuses only on secondary data available in different sources from which the researchers procures comprehensive data and information. Results and conclusion: A family policy that aims to promote combining maternity, and domestic work with paid employment is an effective way to increase the proportion of working mothers/women. It is crucial to not only proportionally distribute the household responsibilities in the family but also to form an effective mechanism of state support for women through the development of the social services sector, as well as the adoption of a system-wide approach to gender equality.
