Recently, an apartment has been changed to be high and diverse. In addition, it has been popularized rapidly. The more number of residents are increased, the more danger of the fire is also increased. If residents are in the upper floor when a fire breaks out, they have much longer evacuation path than the usual. What is more, their condition becomes more unstable. so, riskiness of evacuation is very serious. We should set up environment of evacuation safely. Even though some evacuation system is set up , the dangerous situation is more likely to be occurred. Because it depend on the person. If the person in the building don't recognize that system, it's valueless. Therefore it's very important to understand residents' conciousness level which is related to flee for safety in the fire. In this study, we examine into residents' aware safety level by their residential type. And according to this data, let residents know how they escape from danger . As a result, they can get out of danger when a fire breaks out.

The aim of this study is to represent the residential population distribution in Seoul, Korea more precisely through the dasymetric mapping method. Dasymetric mapping can be defined as a mapping method to calculate details from truncated spatial distribution of main statistical data by using ancillary data which is spatial data related to the main data. In this research, there are two types of data used for dasymetric mapping: the population data (2010) based on a output area survey in Seoul as the main data and the building footprint data including register information as ancillary spatial data. Using the binary method, it extracts residential buildings as actual areas where residents do live in. After that, the regression method is used for calculating the weights on population density by considering the building types and their gross floor areas. Finally, it can be reproduced three-dimensional density of residential population and drew a detailed dasymetric map. As a result, this allows to extract a more realistic calculating model of population distribution and draw a more accurate map of population distribution in Seoul. Therefore, this study has an important meaning as a source which can be applied in various researches concerning regional population in the future.

Lots of previous researches on determinants of apartment prices in Korea consider spatial dependence while few studies regard endogeneity of spatial lag by adding a spatial lag to an OLS regression. Thus, this study intends to include this spatial lag in its analysis of determinants of apartment price in Busan by using a two-stage quantile regression. The empirical results are : the coefficient of spatial lag variable is more than 0.5 and is statistically significant at 1% level. From this result we can confirm that the effect of the price of nearby apartment on that of another apartment is very big. We also find that apartment buyers prefer larger size, height in both the total floors and living floor, south-facing living room with a ocean view, and proximity to metros, high school and coast. Unlike our expectation, however, mountain view is less favored than building view, which we can guess is because apartments with mountain views are mostly located in the low-priced apartment area where some of their living rooms face north. Quantile regression also explains the effect of hedonic characteristics on apartment price better than OLS estimation. For instance, the effect of south facing living room variable on the price is twice larger in high-price apartments than in low-price counterparts. And the effect of vicinity to the coast or the ocean is ten times bigger in high priced apartments.

Remodeling the existing building structure by recycling has great advantages compared with reconstruction in terms of environmentally contributions and reduced use of national resources. And no matter the existing floor area ratio, extension up to 30% of the exclusive using area and short project period have made remodeling a good alternative to reconstruction. However, the residents of aged housings that were being remodeled are either abandoning the remodeling project and turning to reconstruction. The main reason is remodeling project cannot increase the number of householders. In principal, it is prohibited to increase the number of floors during remodeling due to matters of safety. That is, all remodeling construction costs are borne by the residents, which leads to great financial pressure. Therefore, in order to improve these conditions, the residents' burden of remodeling charges should be reduced, and one of the ways to do so is to increase the number of householders. In this study, there will be suggestions of alternatives, including the story increase during remodeling, and compare the burden of remodeling charges on each of the residents, between proposed alternatives and the current remodeling plans by calculating the construction costs in order to prepare a foundation for a system that will promote remodeling.

The study analyzes the appropriate number of people per a household by applying an evacuation simulation to a 27-floor apartment in accordance with the NFPA 101 standard. The results of the analysis are as follows. First, if there are three people residing in each household, there would be 156 households in total, of which 85.25% were evacuated within 5 minutes. Second, 208 households with 4 residents were evacuated within 5 minutes. Third, if there are five people residing in each household, there would be a total of 260 households and 71.92% of residents were evacuated within 5 minutes. Lastly, 62.82% of the 312 households, each consisting of 6 people, were evacuated within 5 minutes. Measures to reduce evacuation time include determining the width of the stairs according to the number of people indoors, the number of floors in the building, the slope of stairs, and the users' characteristics, the design reflecting the ventilation conditions of the stairs, the installment of outdoor evacuation stairs, two-way stairs, evacuation lift, and the installation of an evacuation safety zone for people to evacuate outside of the building in the middle floors. In addition, measures, such as the mandatory installation of automatic emergency door open-close device to the rooftop, are required to facilitate rooftop evacuation.

The purpose of seismic design is to ensure the serviceability of buildings against earthquake, which might be occurred during the service life of buildings, and to minimize the loss of life by preventing their failure under strong earthquake. The lack resistance of walls resulting from a tendency toward high-rise apartment buildings with shear walls and use of piloti would lead to a concentration of inelastic behaviors in their weak story. In this study, the seismic performance of reinforced concrete shear wall buildings haying piloti was analyzed by using the evaluation techniques which was proposed by FEMA 273 and ATC-40. The results from comparison with these two techniques are summarized as follows.; The results of elastic analysis method for seismic performance evaluation show that the effect of piloti and building height decrease performance index. In case of shear wall building, the state of insufficient shear stress governs their overall performance and it becomes evident in the case of the buildings with more than 25 stories. For the buildings of piloti, the change of mass, weak story, as well as insufficient shear stress, decrease the performance index rapidly compared with the performance index of the buildings without piloti. The results, obtained from the nonlinear static analysis using capacity spectrum method, indicate that the performance Point increases for the structure having Piloti and high story. Also, deformation limits of buildings satisfy the allowable criteria at the life safety level, but the immediate occupancy level is exceeded in buildings which have more than 25 stories.

This project was conducted to measure actual temperature, relative humidity (RH), and light intensity at different apartment floors and to suggest suitable indoor plants by investigating morphological changes of Treophelosparmum asiatioum and Fittonia verchaffeltii var. argyroneura as affected by light intensity. Temperature and RH in apartment verandas were measured in three different (2nd, 9th, and 16th) floors on three different buildings for 30 days seasonally. The light intensity, temperature, and RH were recorded outside (parking area) and inside apartment verandas for 24 hours on a selected sunny summer day (between Aug. 19 and Sept. 14, 2008). Based on the first study, we investigated effect of simulated light intensity (40, 70, 100, and $600{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$) on changes in growth and development of T. asiatioum and F. verchaffeltii var. argyroneurain growth chambers. However, daily mean light intensity of 2nd, 9th, and 16th floors was different each other as it was about 40, 70, and $100{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, respectively. In the growth chamber experiment, plant height, internode length, and leaf length and width were not affected significantly by light intensity, but changes in leaf color were apparent in the new leaves with the increasing light intensity. The results suggest that T. asiatioum could be best fit to high, and F. verchaffeltii var. argyroneura to lower floor verandas, considering their aesthetic values.

In this study, we presented a method for estimating the potential population damage of the Seoul Nowon-gu area in the event of a terrorist using a vehicle improvised explosive devices (IED). Using the object-based building extraction method with orthophoto image, the area of the apartment has been determined, and the apartment's height and level were estimated based on the elevation data. Using the population estimation method based on total floor area of building, each apartment resident population was estimated, and then potential population damage at the time of terrorist attacks was estimated around the subway station through a scenario analysis. Terrorism damage using IED depends on the type of vehicle greatly because of the amount loadable explosives. Therefore, potential population damage was calculated based on the type of vehicle. In the results, the maximum potential damage population during terrorist attacks has been estimated to occur around Madeul station, Nowon-gu. The method used in this study can be used various population estimation research and disaster damage estimation.

The number of vehicle has been increased due to growth of economy. Consequently, the needs for parking area has been increasing. there is a serious problem in aged-apartments. It result from observing a parking lot law at that times. That is the reason why residents demand parking lot expansion. Parking lot addition is being studied on a lots different standpoint to solve the present parking lot condition. Parking lot expansion is limited by housing complex characteristics. This study analyzed the housing complex characteristics of aged-apartment. It is analyzed that the number of house holders, distance between buildings, and level of site for finding housing complex characteristics. The result are as follows. the complex lower than 300 households is about 35% in the Number of households. The buildings which has a moving distance from 41m to 50 is nearly 23%. Them the 멕스둣 house located on the flat is 82%. This study will become a reference data for the parking lot expansion.
