  • In case of Korea, immovable property like location, land prise or investment value is more highly estimated than quality of life of residents for performance and value of apartment house, because of limited land area or high density of population. But the high level of life has recently caused the increasing demand in better life. As there is no cases to provide the house in bulk due to the housing market condition, it is necessary to evaluate performance and value of structure, disaster prevention safety, habitability, antiquated condition of building and equipment, maintenance condition and so on that has importantly influence on resident's life quality. So, this study aims to understand the actual condition of environmental performance for the present apartment by comparing the designated apartment, which is ready to have completed in Daegu, with the mixed use residential building, which gained the best grade for green building certification system. Also by analyzing and evaluating a right to enjoy sunshine, floor impact noise etc. and indoor air quality.

  • Purpose: The purpose of this study is to be performed with studio-type housings among urban life-type housings to investigate the physical characteristic and crime-related factors of studios from the viewpoint of the basic principles of crime prevention through environmental design (CPTED). Method: Eight CPTED guidelines available in Korea were reviewed to select 20 planing factors for actual condition investigation. Five single households in studio-type housings in Gwanak-gu, Seoul, were chosen according to the subject screening criteria to perform the actual condition investigation. Results: First, a lighting plan around a building for natural surveillance should consider the building location, relation with the front road, and surrounding facilities. In a building of a piloti structure, the parking lot and the building gate should be arranged in a manner that enables natural surveillance. Second, the shape of the corridors in studio-type housings should be considered to plan the installation of a lighting at the door of each household, the installation of a viewer window at the door of each household, and the arrangement of the elevator. Third, to support access control, an access control system having the function of video and voice communication is recommended to be installed at the building gate. Criteria for the type of security windows and the floors on which security windows should be installed, and the regulations about the CCTV installation inside and outside the building should be prepared. Fourth, to enhance territoriality in parking lots, ground patterns, parking lot gate, and signs may be installed. Fifth, in view of effective utilization and maintenance, lighting facilities should be installed to increase the usability of ground parking lots, and relevant installation criteria should be prepared regarding the type, number, and brightness of the lightings.

  • The in-wheel motor used in green car was designed and constructed for an electric direct-drive traction system. It is difficult to connect cooling water piping because the in-wheel motor is located within the wheel structure. In the air cooling structure for the in-wheel motor, a outer surface on the housing is provided with cooling grooves to increase the heat transfer area. In this study, we carried out the analysis on the fluid flow and thermal characteristics of the in-wheel motor under the effects of motor speed and heat generation. In order to check the problem of heat release, the analysis has been performed using conjugate heat transfer (conduction and convection). As a result, flow fields and temperature distribution inside the in-wheel motor were obtained for base speed condition (1250 rpm) and maximum speed condition (5000 rpm). Also, the thermo-flow characteristics analysis of in-wheel motor for vehicles was performed in consideration of ram air effect. Therefore, we checked the feasibility of the air cooling for the housing geometry having cooling grooves and investigated the cooling performance enhancement.

  • A sirocco fan is widely used for discharging pollutants of a kitchen space since it is able to generate a relatively high air flow rate considering its small size and makes less noise than a axial fan or a centrifugal fan. However, it has a problem because its efficiency is low, and power consumption is larger. Performance of a sirocco fan is influenced by various factors such as number of the fan blades, diameter of the fan, geometry of the fan, geometry of its housing, revolution frequency, static pressure condition, and etc. This research investigated the effect on the performance of geometry of the housing. For CFD analysis, we used a commercial code, SC/Tetra, and used a sliding mesh method to give the same condition as an actual state. Verification of the CFD results is done by comparison of experimental data and numerical one about the suction flow rate, and it is confirmed that two results are well consistent. After we changed the shape of housing according to Archimedes' screw, we observed that suction efficiency is improved by 10.7% maximum.

  • This is a basic study to improve air quality of school classrooms in winter time. The purposes are to check indoor thermal and air environment in school classrooms during winter and to analyze influencing factors on indoor environment. The measurements of students' physical elements with questionnaire surveys were carried out in a total of 6 classrooms. As a result, this research shows that the temperature of one classroom was below indoor thermal standard level, three classrooms had lack of heat, and two classrooms are heated much, which induce relatively low humidity. All of 6 classrooms had lack of ventilation, being high level of $CO_2$ concentration and 2 classrooms are in condition of high PM10 concentration. The majority of students(76%) answered that the cause of their 'heated space syndrome' is because of the lack of ventilation. Students' opening windows for ventilations is hardly carried out at normal times, except that indoor temperature is over standard. That is, we can suggest one of solutions, which is to enable students to operate heating and ventilating system by themselves according to students' physical condition.

  • In order to understand the physical condition and spatial deformation of houses in rural areas in Hodang Village, Ipjang-myeon, Cheonan-si, a rural area with a good settlement environment, physical characteristics and spatial deformation were identified. First, looking at the construction pattern of houses in rural areas, there have been many houses built since the 1990s, and the modernized spatial composition of urban houses appeared. Second, due to the nature of rural housing, work space and residential space are mixed, and it was analyzed that space is used through renovation to solve this problem. Third, Hodang Village was analyzed as an area with good living services, but as a result of the village survey, the proportion of vacant houses was high at 14 (42.4%). This study is conducting continuous rural housing research, rather than a temporary study on rural housing and vacant houses, based on the problems that have been drawn from previous research and existing fact-finding studies.

  • The purpose of this study is to analyze the interior color characteristics of elderly housing facilities in U. S. A. For this purpose, a field survey was conducted between July 23 and July 31, 2003, visiting 10 elderly housing facilities in Contra Costa County, California. A three step analysis of the facilities involved. First, floor, walls, ceilings, base boards and doors in common spaces were examined for the color scheme using the "Pantone for Fashion and Home Color Guide" for each room. Measured Pantone numbers were converted to RGB color using "Chooser 3.0 of Pantone, Inc." Finally, the conversions were recorded as Munsell numbers. The results are as follows: First, the colors chosen for American elderly housing are high value and low chromatic colors. In many facilities, analogue colors such as BG, B, BP and Y, YR R, RP are used. Second, the colors of ceiling and wall are mainly very bright and low chromatic colors. The colors of floor are undertaking an Important role by generating major atmosphere in the America elderly housing. Third, the colors used for elderly housing are found inter-related. For example, the main color in the lobby is also used from corridor to stair and used again from lounge to dinning room as a secondary color. Fourth, it is found that accent colors are used at the beginning and end of stair and corridor outskirts in consideration of physical condition of elderly people. Fifth, there is no difference in color selection between elderly housing with low and high rental value. Preferably, more versatile colors are being chosen for elderly housing with the low rental value.he low rental value.

  • The effects of housing and nutrition on the performance of first lactation sows of the Nepalese Pakhribas breed were investigated. A total of 36 sows, from a previous experiment on nutrition during gilt rearing, were allocated according to a factorial design with 2 levels of nutrition, 60 or 80% of the calculated lactation requirement, and two types of housing, traditional or improved. The mean live weight loss of sows during lactation was reduced to a slightly greater extent by improved housing (p<0.05) than by better nutrition (p<0.10). There was also a significantly lower loss of $P_2$ backfat thickness (p<0.05) and mean body condition score (p<0.05) for sows on the higher plane of nutrition. Piglet weight gain in early and mid lactation was influenced by gestation feeding of the gilt (p<0.10) and by housing (p<0.05). Late lactation gain was influenced only by lactation feeding (p<0.05). In consequence, piglet weight at 42 day weaning was increased to a similar extent by improved housing (p<0.05) and better lactation nutrition (p<0.01). Significantly more sows were remated by day 10 after weaning from a higher level of rearing nutrition ($x^2=13.57$, p=0.001), and from improved housing and improved lactation (both $x^2=4.57$, p=0.033). It is concluded that, under Nepalese village conditions, improvements in housing may be a more cost effective way of improving sow performance than expenditure on additional feed resources.
