High-rise apartments in Korea has physical, environmental, social, economical superannuation. But the remodeling of their apartments is focused on the physical improvement. So they remains the problems of community, safety, economy. Remodeling have to do is to attempt to synthesize the whole superannuation. So we select the B-maul apartments in 1st new towns has the typical problem(parking unsufficiency, small pyeong, ecology shortage etc) of high-rise apartment in the country and analysis its superannuation and remodeling plan. And verify the propriety of a remodeling plan to improve superannuation through an expert survey. Through the tasks, high-rise apartment remodeling in the country need to have a cure for the problem : lowing of the ceiling heights, a shortage of understanding among the residents, and insufficient improvement in the surroundings, no reuse-energy system.

The purpose of this study is to find a way of solving on parking problems at apartment complex through the trend analysis research of the parking demands according to the housing unit size. The subjects of this study are high-rise apartment complexes in Daegu city which are constructed within 10 years. The parking demand according to the housing unit size at apartment complexes had been surveyed every July for 4 years from 2000 to 2003. Specially, we knew that the parking demand of $85 m^2$ below sized housing unit at apartment complex was exceeded architectural regulation of parking supply, and the parking demand of $85 m^2$ over sized housing unit at apartment complex was kept within architectural regulation of parking supply. And, the estimating formula that can predict the future parking demand by the trend analysis according to the housing unit size at apartment complexes in Daegu city was gotten through this study. But, in order to get more accurate estimating formula, it should be based on data of funker research and investigation about apartment complexes and it should be studied continuously.

This paper presents wind pressure distribution on high-rise apartment buildings through wind-tunnel tests. In order to investigate wind-induced interference efforts on building claddings an apartment complex, which was damaged on the claddings during typhoon attack, was exampled and constructed as a scaled model. A series of wind tunnel tests using pressure models were performed in a boundary layer wind tunnel. The test results with and without interfering buildings were compared and discussed. It is observed that the wind pressure on buildings 105 and 106 with surrounding buildings shows highly negative, while the pressure without surrounding buildings were positive. Therefore the wind-induced interference effects should be taken into account in the design of claddings through wind-tunnel tests.

This study was carried out to analyze the change of wind filed and heat island according to the location of the high rise building using micrometeorology numerical model Envi-met3.0. In this study, the real urban planning of Jeonju city was used as input for the location and height of buildings. Modeling was performed for two conditions as input data. Case 1 is that wind direction is SSE and case 2 is W. To analyse the change of wind filed, wind speed results were used. To analyze the change of heat island, temperature results were used. Below the building height, wind speed increased 0.2~2.5 m/s at the inflow area and decreased 0.5~2.0 m/s at the area between the buildings. Above the building height, wind speed decreased 0.1~0.8 m/s near the building complex. On the other hand, wind speed increased 0.2~0.4 m/s in the outside area of the building complex. In the case of temperature, below the building height, temperatures increased $0.01{\sim}0.1^{\circ}C$ in the building complex and leeward area. On the other hand, temperature decreased $0.01{\sim}0.005^{\circ}C$ in the outside area of the building complex. Above the buildings height, temperatures decreased $0.05{\sim}0.2^{\circ}C$ in most of the area.

In this study, the changes of the sunshine environment due to the construction of buildings were analyzed by season. Using a geographic information system (GIS) data, the topography and the buildings were constructed around Pukyong National University (PKNU) in Busan. The numerical model was performed for a week in each season, before and after the construction of buildings. Even before the construction of the high-rise building complex, the area of sunshine block is wide due to the apartment complex located in the southeast of the PKNU campus and the mountain in the south. After the construction, the sunshine-blocked area became wider after the sunrise and before the sunset. The area of sunshine block after 1 hour at sunrise increased by 1.60%, 1.50%, 1.58% and 1.36% in the vernal equinox, summer solstice, autumnal equinox and winter solstice, respectively. The building complex in the east (south) of the PKNU campus made shadow in more than 1,000 m (750 m) toward the west (east) just before the sunrise (sunset). Especially, the sunshine duration in PKNU campus decreased by 46.61%, 22.75%, 58.56%, and 11.31% in the vernal equinox, summer solstice, autumnal equinox and winter solstice, respectively. The analysis of the sunshine duration for a dormitory building showed that the construction of the building complex in the south of the PKNU campus reduced the sunshine area of the western (southern) wall of the dormitory by 30.91% (49.45%) for a winter week.

Under the ownership pre-sale system in the South Korean apartment market, developers can sell apartment ownerships as soon as they start to construct an apartment complex. In the South Korean apartment market, people call this kind of ownership "Bun-yang right." There is a time difference between ownership sale and apartment completion under the ownership pre-sale system. The pre-completion apartment ownerships can be resold to third parties until the apartment complexes are completed, which is called "Geon-mae" of the Bun-yang right. Using survival analysis, this research analyzed the elapsed time between ownership purchase and resale to a third party using 48,316 apartment units nationwide in the 192 complexes supplied from 2000 to 2016. Specifically, this study analyzed the influence of the real estate policy, contract term, location, apartment complex, and unit characteristics on the elapsed time between ownership purchase and resale to a third party. The empirical analysis revealed that the real estate policy and contract term characteristics have a significant effect on the elapsed time between ownership purchase and resale to a third party. Also, this study confirmed that the product characteristics, such as the location and apartment complex and unit characteristics, have an influence on the elapsed time between ownership purchase and resale to a third party.
