The purpose of this study is that problems caused by labor environment of cuisiniers in hotels need to be considered and studies regarding a part-time cuisinier in a special-grade hotel need to be conducted. This study analyzes the influence of labor conditions and organizational commitment of a part-time hotel cuisinier on duty satisfaction. It consists of two parts: a research based on the review of the literature and empirical study methods. The method of human resource management in hotels such as treatment of a part-time cuisinier in a special-grade hotel and the way of management as a result of an empirical study are proposed. First, as a result of conducting research on duty satisfaction to part-time cuisinier, most of them are highly satisfied with their duty regardless of their age and academic backgrounds. Second, men hold a majority; woman staffs tent to have a had time working overtime considering the situation that hotels run for 24 hours. That is the main reason why less woman staffs work in hotels than man staffs do. Part-time staffs would like to work consistently after they get upgraded to a regular worker. Forth, it is considered to break down into detailed sectors and speciality is highly demanded.

This ethnographic case-study explores the interpretation and behavior in job considering among full-time housewives. The participants of this study are eleven middle class full-time housewives in their thirties and forties. In-depth interviews based on an unstructured Questionnaire were conducted for this study. Findings are as follows: Six full-time housewives tend to think their full-time housewife-lives more convenient, something unable to substitute and more profitable compared to the counter partner's lives. But they are classified into two groups according to the satisfaction for full-time housewife life. One group has found out more positive meaning in their life but the other group has not yet and they are doubtful about real life and other opportunity. In Contrast, other five full-time housewives tend to interpret employment as a more productive source to secure family resource for their children's education and repay the loan used to buy larger apartment. And the job is considered to confirm her own individuality and the feeling for the social entity as a competent social entity. But two of them who have never been employed do not try to get a job as a new identity alternative. And the various elements like household income, job experience, health, children's age and husband's attitude to his wife's employment etc. are defined to influence the interpretation and the job considering behavior among full-time housewives.

The purpose of this study was to present an analysis model for finding the correlation between visibility and evacuation time as users move in the outpatient department of the general hospital. The spatial scope of the study was limited to the first floor and second floor which are used for the outpatient department. Traffic density in outpatient departments was surveyed on site. Based on the surveyed traffic density, the evacuation simulation model was established for calculating the escape route and evacuation time for an individual user. The traffic density of the outpatient department as per the evacuation time was also calculated. With using evacuation simulations, the flow of evacuees was calculated through the density of traffic over the time of evacuation. Visibility data were set in the simulation model for users' escape routes. A correlation analysis between the product of evacuation flow measure and visibility measure of the evacuation population and evacuation time was performed. The analysis result showed negative correlation within a specific distance range. This study presented an analysis model showing that the evacuation condition considering spatial visibility in the outpatient department of general hospital visibility was negatively related to the analyzed evacuation time at the design stage.

Fieldbus is the lowest level communication network in factory automation and process control systems. Performance of factory automation and process control systems is directly affected by the data delay induced by network traffic. Data generated from several distributed field devices can be largely divided into three categories: sporadic real-time, periodic real-time and non real-time data. Since these data share one fieldbus network medium, the limited bandwidth of a fieldbus network must be appropriately allocated to the sporadic real-time, periodic real-time and non real-time traffic. This paper introduces a new fieldbus design scheme which allocates the limited bandwidth of fieldbus network to several different kinds of traffic. The design scheme introduced in this study not only satisfies the performance requirements of application systems interconnected into the fieldbus but also fully utilizes the network resources. The design scheme introduced in this study can be applicable to cyclic service protocols operated under single-service discipline. The bandwidth allocation scheme introduced in this study is verified using a discrete-event/continuous-time simulation experiment.

The purpose of this study is to investigate the participation in social activities by full-time housewives with infants and preschool children. The data in this study comes from a 1 percent free sample of the 2010 Population and Housing Census collected by Statistics Korea. The statistical methods for this study were percentage, chi-square test, and logistic regression analysis. The findings are as follows. First, there are differences in participation in social activities according to number of infants, number of preschool children, and number of elementary schoolchildren. Second, there was the difference in participation in social activities between full-time housewives and full-time wives' husbands. Third, factors like full-time housewives' age, educational level, number of preschool children and elementary schoolchildren, number of rooms, and occupancy status affected participation in social activities by full-time housewives. These results show that full-time housewives were under pressure in relation to participation in social activities because of their caregiving labor but participated in religious and educational activities actively.

Time-tradeoff measures and healthy years equivalents were assessed and compared through an empirical study based on Multi-attribute utility theory. The study included 33 student subjects as a pilot study, and 54 end-stage renal disease patients in Wisconsin. The two outcome measures were compared with the survival duration of 1, 5, and 10 years. The results of the study show that the time-tradeoff method and the two-stage method did not lead to the same numerical quantities, although they aim to measure the same quantities (equivalent numbers of healthy years) theoretically. The healthy years equivalents involved more inconsistencies, and were less reliable than the time-tradeoff measures. Overestimation of the healthy years equivalents was observed. This seemed to be caused by the complex procedure of the two-stage method as well as by the preferences assessment biases. Based on the study experiences, the time-tradeoff measure would be recommended for problems involving generic medical applications and health policies.
