The purpose of the study is to suggest the amount of space for each behavior according to the classification of behavior in the housing to plan the optimal floor space of the elderly housing. The method for calculating space for behavior begins with classifying behaviors, identifying them and then taking pictures of the model of elderly people who reproduce each behavior. Based on the pictures, body parts which are necessary for each behavior are assembled and the formula for behavioral space is created. The space for behavior is produced considering the body dimensions of Korean elderly in their sixty's as well as the furniture size and the psychological distance between people. 3D modeling is used to verify the result. Human behaviors can be classified into individual-related, housework-related, family-related, reception-related and other behaviors. These five behaviors are subdivided into more specific behaviors. The area for each specific behavior is calculated with the anthropometric data of the elderly, preferred furniture dimension and psychological area. As a result the required area for specific behaviors is as follows: the behavior of sleeping in a bed needs $4.3m^2$; the behavior of changing clothes on a chair, $1.7m^2$; the behavior of watching TV on the floor $1.3m^2$, the behavior of working and reading using a desk, $2.1m^2$, the behavior of exercise, $2.5m^2$; the behavior of showering on a chair, $1.3m^2$ and showering using a wheelchair, $1.9m^2$; the behavior of toileting using a wheelchair, $2.3m^2$; the behavior of washing up using a wheelchair, $1.9m^2$; the behavior of eating using a table for four persons, $4.4m^2$; the behavior of cooking and washing dishes, $0.9m^2$ per counter-top; the behavior of washing clothes using a washing machine, $0.9m^2$; the behavior of ironing on the floor $1.4m^2$; the behavior of reception(three persons) on the floor considering personal space, $4.0m^2$; the behavior of taking on and off shoes on a chair, $1.3m^2$. The result of the study is utilized as quantitative data to calculate optimal floor space for elderly housing. In addition, qualitative data such as characteristics of housing preference, spacial usage and storage capacity are necessary to produce the floor space which can provide convenient and safe living environment.

This study is analyzed comparison about the component ratio of dwelling space in the existing plan and residents dwelling needs. Also, it is analyzed the residence factors of area component change that residence satisfaction and importance according to the behavioral patterns of residents. The results are as follows. 1) Total area component ratio of the existing plan was 39.5:40.8:19.7% and dwelling consciousness one was 36.4:44.0:19.6%. Compared private space with public space, public area requested increase rather than private area. 2) In the 17, 19pyung-types dwellers are not happy about dining kitchen and utility room and types of 21, 23pyung-types are dissatisfied in room-2 and room-3, living room and dining kitchen are dissatisfied, too. In case of areas over 25pyung-types are dissatisfied in room-3 and room-4. 3) The behavioral patterns of apartment residents were classified six acts, and the most significant factors are appeared associated the acts of ceremony, relation of neighborship, and reception. The next significant factors are appeared associated the acts of family relation, about food life. So, it is concerned with the scale of public room.

도시의 인구 밀집도가 증가함에 따라 도시의 단위 면적당 건물 밀집도 역시 증가하고 있으며, 이에 도시 화재는 대규모 화재로 발전할 가능성이 높다. 도시 내 대규모 화재로 인한 인명 및 경제적인 피해를 최소화하기 위해 시뮬레이션 기반의 화재 대응 방안들이 널리 연구되고 있으며, 최근에는 시뮬레이션에서 효과적인 화재 대응 방안을 탐색하기 위해 강화학습 기술을 활용하는 연구들이 소개되고 있다. 그러나, 시뮬레이션의 규모가 커지는 경우, 상태 정보 및 화재 대응을 위한 행위 공간의 크기가 증가함으로 인해 강화학습의 복잡도가 증가하며, 이에 따라 학습 확장성이 저하되는 문제가 발생한다. 본 논문에서는 시뮬레이션 규모 증가 시 강화학습의 학습 확장성을 유지하기 위해, 화재 상황 정보와 재난 대응을 위한 행위 공간을 변환하는 기법을 제안한다. 실험 결과를 통해 기존에 강화학습 모델의 학습이 어려웠던 대규모 도시 재난시뮬레이션에서 본 기법을 적용한 강화학습 모델은 학습 수행이 가능하였으며, 화재 피해가 없는 상황의 적합도를 100%로 하고, 이것 대비 99.2%의 화재 대응 적합도를 달성했다.

This study investigates whether earnings management behavior of chaebol firms differ from that of non-chaebol firms. The ownership structure of chaebol firms is characterized by the dominance of one largest shareholder and his family members who typically participate in the management of the firm directly or indirectly and influence most of the important management decision. This study adopts the random effect model and the hausman and talyor model, using a panel of 5092 firm-year over a period from 1991 to 2010 to control for potential heterogeneity and endogeneity that may cause sever bias. This study finds that there is no difference in accrual based earnings management level between chaebol firms and non-chaebol firms. However, chaebol firms appeared to engage less real earnings management that is known to negatively affect future earnings and share prices. The results are consistent when controlling for potential heterogeneity and endogeneity in the hausman and taylor model. The results may be of interest to various stakeholders, policy makers, standard setters and academic researchers.

Recent time, there appear many cases of remodeling construction concluding enlargement of exclusive using area in Apartment. These constructions show several phases according to the size of apartment and use of the each room. In small size apartment the cause of enlargement construction is usually the desire for having enough dwelling space. But in large size apartment that is usually the desire for having usuful and effective dwelling space. In these remodeling constructions owner or designer change the interior design of each rooms and the Intoner materials. These changes show several tendencies by the sizes of apartments and use of the each room.

The study on bathroom plan for the elderly who use wheelchair has been done continuously. However, the elderly's behaviour at the bathroom and consideration for the caregiver has been underestimated. In this perspective, the purpose of this study is to find out how much more bathroom size is needed for the elderly who use wheelchair and the caregiver based on their behaviours. The study method is as follows: First, behaviours which occur at bathroom were collected from the previous research. Second, the size needed was calculated based on the elderly and caregiver's movement. Third, the size of bathroom enough for the impaired elderly with caregivers was suggested. The room next to shower booth and bath tub should be expanded for the caregiver. In addition, the room beside the basin should be added as much as $600{\times}600$ to let the caregiver stand and support the elderly when they are needed to wash their hair. As a result, the size of bathroom should be at least planed as follow; $1.3m^2$ more for type A, $1.5m^2$ more for type B, $1.6m^2$ more for type C, and $1.1m^2$ more for type D. As the bathroom is the room that the elderly want to modify for their rest of the lives, the room should be reserved enough from the early stage of design, so that this will make the elderly be possible stay at the place until they want to stay.

Landfill has been a long pending issue in the Seoul Metropolitan Region since it was created. Adopting Painter's notion of "territory-effect," this paper analyzes the network formation and change of diverse actors and territory as an effect of networked relations according to four periods from the creation of the landfill to current extension of landfill use. The results are as followed. First, the network formation and composition of major actors has been changed together with historical-geographical conditions. Second, these networks created territory as an effect and re-articulated the configuration of conflicts and solidarity of diverse actors. Third, territory created as an network-effect are different in each period, and is continuously reterritorializing. These findings suggest that territory is never complete and always in the making.

The recently-introduced Special Use Permit system is an exceptional approval system for private park developers to develop unexecuted urban park sites into urban parks with the implementation of profit-generating businesses within the boundary of preserving the original function of the park under an agreement with local authorities. This thesis studies the application of this system. This is a feasibility study of cases that have contributed to the acceptance of intended park sites by developing some parts of park sites as public housing, focused on unexecuted urban park areas for the long term in Suwon City based on the Special Use Permit, and creating other sites as park area. First, it has been judged that realization of business is possible at 300 percents of the floor area ratio in case of flatland neighborhood park which has high appraised land values. It is judged that realization of business is possible within a 10 percents size of private land at 200 percents of the floor area ratio in case of woodland and waterside neighborhood parks that have low appraised land values on the outskirts of the city. Second, through working expenses combining compensation and money for park construction, a balance of business profit can be understood within about 50 percents of total expenditures. Because the public contribution ratio by the Special Use Permit can be presumed as about 50 percents of total expenditures, it implies that windfall profits by the Special Use Permit can be adequately collected.

The long term land-cover changes and the pattern of morphological changes in foredune ridges and unvegetated dunes were investigated for about 30 years through analysing aerial photographs in Shinduri coastal dunefield, Korea. As a result, forested dune area increased while unvegetated dune area decreased continuously since 1967. Foredune ridges retreated landward about 80m away from the former coast-line in the middle part while they advanced seaward after construction of dike in the northern part during last 3 decades. Unvegetated dunes in the middle part of the dunefield were eroded at seaward side and moved landward away. These facts mean not only coastal dune area has been affected by man-made effects such as afforestation and coastal developments but also shinduri coastal dune area has been stabilized by plants and has been negative sediment budget.
