Objectives: The objectives of this study were to determine the psychological fatigue and analyze muscle activity of production workers who are performing processes jobs while standing for prolonged time periods. Methods: The psychological fatigue experienced by the workers was obtained through questionnaire surveys. Meanwhile, muscle activity has been analyzed using surface electromyography (sEMG) measurement. Lower extremities muscles include: erector spinae, tibialis anterior, and gastrocnemius were concurrently measured for more than five hours of standing. Twenty male production workers in a metal stamping company participated as subjects in this study. The subjects were required to undergo questionnaire surveys and sEMG measurement. Results: Results of the questionnaire surveys found that all subjects experienced psychological fatigue due to prolonged standing jobs. Similarly, muscle fatigue has been identified through sEMG measurement. Based on the non-parametric statistical test using the Spearman's rank order correlation, the left erector spinae obtained a moderate positive correlation and statistically significant ($r_s$ = 0.552, p < 0.05) between the results of questionnaire surveys and sEMG measurement. Conclusion: Based on this study, the authors concluded that prolonged standing was contributed to psychological fatigue and to muscle fatigue among the production workers.

The intent of this study is to propose a method for appraisal of the indoor thermal environment of apartment housing by measuring physical factors and residents' response to questionnaire survey. The experiments were performed on eight houses each in summer (August 18 through 31,1995) and winer (february 16 through 20,1996). It included measurements of indoor air temperature, globe temperature, relative humidity, and CO2 concentration. The questionnaire surveys were performed each in summer (July 16 through 20, 1996) and winer (February 13 through 16, 1996). And 248 cases in summer and 297 cases in winter were used in analysis. These questionnaire surveys asked residents' response about thermal sensation, humidity sensation, sense of air freshness regarding the indoor thermal environment. data acquired through the experiments and questionnaire surveys were then transferred to scales that allowed relative comparison, and measured to an appraisal standard chart. Appraisal tools included appraisal charts and radar charts. Indoor thermal environment was judged to be positive according to experiments, but residents appraised the thermal environment to be average. This difference between the two can be found in the strict standards by which residents judge the thermal environment of their apartments.

Objectives: A web-based survey has been administered annually since 2005 throughout Korea to assess the prevalence of adolescent health risk behaviors among middle and high school students. The aim of this study was to evaluate the test-retest reliability of the Korea Youth Risk Behavior Web-based Survey (KYRBWS) questionnaire. Methods: A convenience sample of 2298 middle and high school students participated in self-administered questionnaire surveys twice, approximately two weeks apart, in 2008. The percent agreement, kappa statistics, and prevalence rates at the first and second surveys were computed for the core subset of 39 self-reported health risk behavior indices of the KYRBWS. Results: Among 39 indices, seven indices had kappas $\geq$ 0.81 and all of the indices had kappas $\geq$ 0.41. Based on nonoverlapping 95% confidence intervals, three indices had significantly different prevalence rates between the first and second surveys. In the subgroup analyses by school grade and gender, two indices had significantly different reliability estimates between middle and high school students. There were no significantly different reliability estimates between male and female students, except for one index. Conclusions: This study demonstrated that the reliability estimates for the KYRBWS questionnaire are varied, but generally reliable over time. The indices with low reliability estimates need to be evaluated further in order to determine whether the indices should be modified or deleted from future versions of the KYRBWS.

This study intends to establish a system to investigate and analyze various impacting factors to Rural Housings such as the relationship of characteristics of Rural Housings located in a Rural Village to the Village and a Unit Housing, to the External and Internal Spaces inside the Unit Housing and the Village, and to Living Characteristics of the Residents and Space from an integrated point of view. The results of this study are largely summarized as following four kinds. Rural Housing Survey System can be largely classified into three stages, and they are a Preliminary Survey, Basic Survey and In-depth Survey. Along with these, the scope of the survey contents can be divided into a survey result by a unit of village, of land, of housing, and of resident's opinion survey. Secondly, the surveys by village unit are on location properties, Village Identity, Street Network, Land Use, Landscape Features and Public Facilities, and consist of Literature, Discussion and Field Survey. Thirdly, the land Unit Surveys are on a Driveway, Gate Location, Housing Placement, Outer Space Design in a Yard and Outer Space Use Characteristics, and consist of Questionnaire and Field Surveys. For the fourth, the Housing Unit Surveys are on an Internal Space Design and Placement, and consist of Questionnaire and Field Surveys. Finally, the Resident Questionnaire Survey consisted of Entire Discussion Survey and a Household one, and then the Entire Survey was on the Village's History, Village's Characteristics, Cultivation Characteristics and Community Activities while an individual one was on Main Living Characteristics, Satisfaction and Utilization Characteristics.

Through an examination of future societal development, it was found that the demographic structure is gradually aging, thus placing higher demands on elderly welfare centers. This study conducted surveys on three elderly day care centers in the entire region, aiming to enhance the pivotal role of elderly day care centers in the welfare facilities for the elderly. The current usage status, interior architectu/ral evaluations, and questionnaire surveys of these centers were analysed. The results of investigation into the architectural environment of the elderly day care centers showed that in terms of physical environment, smaller-scale centers did not lag behind larger ones in internal facilities, but larger-scale centers excelled in spatial utilization. Furthermore, the results of questionnaire survey results revealed correlations between family relationships, health status, level of assistance required, and satisfaction with facility usage, while no correlation was found between usage time, health status, and satisfaction with facility usage. This study conducted basic investigations such as architectural and physical surveys, and questionnaire surveys on elderly day care centers. Based on the survey results, future design practices should continuously explore and innovate to meet the needs of an aging society, further improve the community care system, provide more comprehensive and meticulous services for the elderly, and lay the foundation for enhancing the quality of life for the elderly and providing comfortable services.

There are no formal decision tools or guidelines to assist owners and contractors in choosing delivery systems and project strategies that would allow for a radical reduction in project cycle time - from the preplanning phase through project start up. Therefore, it is important to identify the state-of-practice and the state-of-art on methods of achieving radical reduction defined as a reduction of 25% or more in overall project cycle time. A comprehensive literature review, three questionnaire surveys, and the seven case studies were conducted and the data obtained from them were analyzed to establish the state-of-practice and state-of-art for project cycle time reduction techniques.
