The purpose of this study was to investigate the characteristics of leisure behavior and preference for leisure environment of the five-day workweek company employees according to gender for developing leisure facilities in residential community planning. The questionnaire survey was used. The subjects of questionnaire survey were 338 staffs of 7 companies, who were living in apartment complex. The questionnaire consisted of way of life about leisure, leisure necessity, actual condition and need of leisure spaces, and leisure satisfaction. Frequency, percentage, and mean, ${\chi}2-test$, t-test, and factor analysis were used for data analysis. The major results were as follows. 1) In terms of leisure time in weekend, the available leisure time distribution, and leisure cost, there were not difference between men and women. 2) After five-day workweek, the men and women showed to increase their leisure activities and to engage in diverse forms of leisure. Also, they showed an increased desired ratios in participating in each leisure activities. 3) Leisure was necessary to strengthen the unity of family and cultivate the sentiment. 4) Even though current main area for leisure were in their house, men were likely to change them from in the house to around and near their house. And they needed leisure facilities which was closer to their house. 5) The degree of satisfaction of leisure facilities in residential environment was low and there were not difference between men and women. This result implicated to improve and develope leisure space and facilities near the residental environment for promoting leisure behavior of both women and men. In particular it is necessity to create the good atmosphere of leisure facilities for women.
The ventilation system is a key device to ensure both healthful indoor air quality (IAQ) and thermal comfort in buildings. The ventilation system should make the IAQ meet the standards such as ASHRAE 62. This study deals with a new approach to modeling the ventilation and IAQ requirement in residential buildings. In that approach, Elite software is used to calculate the air supply volume, and CONTAM model as a multi-zone and contaminant dispersal model is employed to estimate the contaminants' concentrations. Amongst various contaminants existing in the residential buildings, two main contaminates of carbon dioxide ($CO_2$) and carbon monoxide (CO) were considered. CO and $CO_2$ are generated mainly from combustion sources such as gas cooking and heating oven. In addition to the mentioned sources, $CO_2$ is generated from occupants' respirations. To show how that approach works, a sample house with the area of $80m^2$ located in Tehran was considered as an illustrative case study. The results showed that $CO_2$ concentration in the winter was higher than the acceptable level. Therefore, the air change rate (ACH) of 4.2 was required to lower the $CO_2$ concentration below the air quality threshold in the living room, and in the bedrooms, the rate of ventilation volume should be 11.2 ACH.
Urban stormwater runoff is the one of the most extensive causes of deterioration of water quality in streams in urban areas. Especially, in the Suyeong River watershed, non-point sources from urban-residential areas are the most common cause of water pollution. Also, it has been ascertained that BOD and COD as indexes of organic matter, have limitation on management of Suyeong River's water quality. In this study, changes of organic matter properties of Suyeong River from inflow of non-point source during rainfall were investigated. Fractions of organic matters were analyzed using water samples collected at two sites (Suyeong River and Oncheon Stream) during a rain event. Variations of dissolved organic carbon (DOC) concentration by rainfall were similar to flow rate change in the river. Distribution of organic matter fraction according to change of rain duration revealed that while hydrophilic component increased at initial rainfall, the hydrophobic component was similar to change in dissolved organic carbon (DOC) concentration. Also, the relative proportion of hydrophilic components in organic matter in river water increased, due to rainfall. Results of biodegradation of organic matters revealed that decomposition rate of organic matters during rainfall was higher than that of during a non-rainfall event.
The objective of this study is to verify the safety in case of fire and change of residential environment for different wall construction approaches in a stairways apartment house. In order to confirm that case_1, which is current case that most of wall is opened and the case 2, which upper part of wall is limitedly opened are compared and analyzed based on simulations of fire, escape and natural ventilation performance. The analysis reveals that possible escape time for case 1 was more than 600 seconds and for case 2 was 195 seconds. Since the escape times for both cases were over 128 seconds, it would be reasonable to assume that every resident would escape. The simulation results on natural ventilation performance shows the air change per hour of case 1 and case 2 were .19n/h and .16n/h and there was 1.2 times difference. However, the difference was too insignificant and it could be seen as that different approaches on wall construction would not significantly influence on natural ventilation performance.

Population ageing and the disabled population is increasing. so disabled population and elderly people in the physical environment for Barrier-Free recently has been getting attention. according to a recent welfare paradigm shift of life support promoting for the housing remodeling. but basic remodeling made of simple living environment improvement and facilities installation for the type of disability customised housing remodeling. efficient housing remodeling plan for remodeling before and after through change the safety accidents occurred ratio. living environment for the improvement of housing and reconstruction for the benefit of comprehensively considering for disability subject in Indoor living type and the type of disability, housing type etc. and personalize house was remodeling for corresponding each space problem for identify obstacles and living types. as a result satisfaction changes & safety accident rate changes as follow. first, have complained that there was a in to residents environment furniture for reconstruction of the former housing remodeling needs survey. 80.2% of total for the percentage of households with high needs remodeling. second, The survey did not meet the 29 furniture as after the construction for died about recipient & up sticks & long absence. this leave out after the safety accident Corporation about 101 housing in the 88% of households did not happen. as a result, the lower the ratio of safety accidents occurring very revealed. third, grasp the meaning for indoor living type. showed that each approach(83%), front porch(90%), kitchen, living room(91%), bedroom(93%), toilet(92%) for each space remodeling satisfaction flow through customized housing remodeling.
According to the change of the life environment and economic growth, the more highly a city has developed, the more concentrated is the urban function. That is, a city is required for adding more infrastructure. But, both limited land resources and financial problems made it impossible to add infrastructure. So, the necessity of multi-dimensional planning of urban infrastructure was recognized. Especially, in the urban residential area, a mixed-use of the playground of a school and the empty space of a park is desired to serve the issue of insufficient parking spaces. Schools and parks are closely connected to the center of a town, and playing a central role for the town life. For this reason, they are highly demanded in urban residential areas and also expected to be effective. However, we need to consider not only parking convenience but also the safety of users in design process, because people using parks and schools include young students and the elderly. In this study, we mainly examined physical characteristics and the utilization of schools and parks with parking facilities in urban residential areas. Then, we analyzed cases through comparing and evaluating in terms of convenience and safety. and weighed up advantages and disadvantages of each through the comparison of the schools and the parks having parking facilities. The results of this study are expected to provide fundamental references for preparing design standards for such facilities.
Since aging population in Korea is rapidly progressing, the need for improving the life quality of the elderly has been increasing. Accordingly, in order to respond in a residential environment improvement and behavior change for the elderly, architecture design and construction methods have become converted into a modular construction method and various IT systems for the elderly have been proposed. Unlike current residential design techniques for the elderly in which architectural design techniques are performed separately with IT system design, the methodology for converging architectural design techniques with IT has not been discussed and proposed. Therefore, this paper extensively studies about requirements for converging architectural design techniques with IT such as elderly behavior, residential IT Service plan factor analysis, and residential modular construction method including IT services.
The purpose of the study is to provide basic data to be useful for living environment of National Rental Housing, through comparative analysis of residential conditions, community consciousness of residents, characteristics of 3 complexes, whose residents have lived more than 3 years, different in area and size. Deungchon 11 Complex in Seoul, Eui-wang Naeson Complex, and Incheon Samsan 4 Complex are chosen for the investigation and the survey and 242 copies of the questionnaire are analyzed for the final result. Analyzing the contents of the survey results are as follows those deriving conclusions and suggestions. 1) Housing and construction standards are required to reconsider for enhancing of community consciousness and housing satisfaction of residents of National Rental Housing. 2) Spending on residential move, and minimize the unnecessary expense of low-income housing need to do to promote stability. 3) Facilities and equipments for residents are needed considering barrier-free design which introduces universal design. 4) Welfare facilities such as culture space and after-school classroom for teenagers are needed. 5) By using the broadcast media actively pro-mote, various layers are encouraged moving into National Rental Housing, through the concept of housing opportunities for change. 6) In short-term, community space are need remodeling and various activity programs are developed to induce activation of community facilities. In long-term, users considering a community facility plan, actively promoting activities, methods and operating system support for the government in the continuing policy and management is needed, when the National Rental Housing are planned to build. Therefore, the organic aspects such as the development and operation of the community program as well as the physical aspects such as the community space and facilities for the active community of the National Rental Housing are constantly considered in the follow-up studies.

Today, rapid progress of urbanization is discovered commonly in many countries, especially in developing countries, which has led to spatial order and development process of city. Historically, Taegu was a walled city and formed mono-nucleus which was restricted by the castle. As the city grew gradually, the castle was removed as a result of diversification in traffic network, change of socio-economic environment, formation of industrial base and functional distribution. According to reconstruction maps of residential patterns, there was distinctive residential segregation among ethnic groups. Koreans in Taegu in 1939, aggregated densely in the southern and western parts of the city. The Japanese were concentrated densely in the northern and eastern parts of Taegu. And the street pattern within residential areas of the Korean people was shaped like a maze type in contrast with Japanese residential areas, which showed grid pattern of streets. This is another general pattern of almost all colonial cities, especially in Asia. Through this process, today it appears that, out of overall residential areas which occupy the highest ratio in urban land use, those for eminent people influence the functional development of urban spatial structure very heavily as a key point in urban residetial structure. Truly, residential segregation can be seen as the spatial manifestation of uneven distribution of such important scarce resources as housing and residential environment. In this study, the characteristics of locational distribution of the eminent people show their socially and economically stabilized standing in Taegu, taking the aforesaid situation as a background of the study. And the process of this study is as follows ; to examine the forming process of residential areas in the city as a theoretical supporting, to put in order on classical interpretation to formation of residential areas, and general type modern residential areas formation, and economic decision factor of land use. Therefore, this study aims to examine growth and development of eminent persons' residential areas and, at the same time, extract locational characteristics through the pattern of eminent persons' location and predict changes in the future.
