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.

According to Geum-River restoration project, given conditions for management of water environment in the Geum-River were changed. Because of those changes, this study was investigated the establishment of water quality standards and water quality target in the Geum-River basin. For management of water environment in the Geum-River, the sub-basins and watersheds are newly divided and the water quality and ecosystem standards in the sub-basins are reestablished. Considering the consistency of water environment policy and legal system, the legal name of sub-basins and watersheds are unified. TMDL (total maximum daily load) should be implemented in the sub-basin where exceeds the water quality standards and the number of water pollutant among the water quality parameters which exceeds the water quality standards are extremely minimized. The water quality target of water pollutant for implementation of TMDL should be established same or higher concentration of water quality standards.

There have been strong arguments that the best organizational type for the information society is a network organization which is intelligent and learning-oriented as well as has problem solving capacities rather than a traditional passive organization which strictly follows standard operating procedures. In this perspective, integrated information work environment emerges as attractive work environment for the 21st century. Integrated information work environment is defined as an integrated electronic environment that is available to and readily accessible be each employee and is structured to provide immediate, individualized on-line access to the full range of information, software, guidance, advice and assistance, data, images, tools, and assessment and monitoring systems to permit job performance with minimal support and intervention by others. Case study was performed to measure the productivity improvement by implementing integrated information work environment in life insurance company. The results show that there is a number of indications of strong work productivity improvements.

The aims of this study were to investigate the relationships among mothers' depression, home environment, and preschool children's development. The participants in this study were 199 parents of 3- to 5-year-old children. Statistical methods used for the data analysis were the frequencies, means, standard deviations, Pearson correlation, simple and multiple regression. The major findings were as follows. First, mothers' depression had a negative influence on home environment. Second, mothers' depression had a negative influence on children's development. Last, the effect of mothers' depression on children's development was partially mediated by home environment. The results suggest that mothers' depression and home environment may predict children's development.

This study is intended to forecast changes in Ubiquitous technology-based residential environment since the digital revolution so as to suggest the direction of furniture design in the near future. Among Ubiquitous technologies, the intelligent digital technology applied to a residential environment is defined as "Smart Digital Technology." Ministry of Commerce, Industry and Energy named the residential environment where such technology is applied "Smart Home." Smart Home is strategically creating intelligent residential environment where interactivity is made between human, furniture and residential environment, based on home automation, home network and intelligent sensor technology. Smart furniture is based on strategic characteristics of smart home. Its convergence with IT equipments is being made. Largely, smart furniture has three characteristics as below: First, smart furniture provides users with information on home management, health management, education and fashion. not just functioning as storage space. Second, smart furniture that is a new lifestyle pattern will suggest a new aesthetic standard based on unsettled shapes and innovative structure. Finally, it gives convenience to users intelligently. Namely, smart furniture, "intelligent informative furniture", will be suggested as a new paradigm.

In a military maintenance system, the standard maintenance man-hour of weapon systems is a tool to estimate the maintenance capabilities of maintenance units, provide standards for determining the maintenance needs and workload, and provide basic data for establishing a maintenance plan. The standard maintenance man-hours of major weapon systems have already been derived and used, but the standard maintenance man-hour in a wartime maintenance environment has not been computed. Therefore, the standard wartime maintenance man-hours need to be derived and This study proposes a process and method of computing the maintenance man-hours. In addition, this work suggests the criteria of collecting and screening data that is necessary for estimating the standard maintenance man-hours and introduces a methodology for analyzing the characteristics of maintenance man-hour distribution in the process. The proposed process first designs a model that reflects the wartime maintenance environment, selects statistical techniques, collects maintenance data, analyzes the descriptive statistics, estimates the distribution, and finally presents representative values of maintenance man-hour. Based on the proposed method, the standard wartime maintenance man-hours of the four weapon systems were calculated, and the distribution of the maintenance man-hours was analyzed to follow a lognormal distribution, and the method presented reliable results.
