The research objective of this thesis aims to utilize the history and culture of cities as resources and to solve the problems of modern urban environment which can produce non-personality in the age of globalization. This study deals the Sustainable Urbanism and Architectural System in the Historical city ; First, Historic resources and its spatial characteristics. Second, reused resources and remodeling of existing building. Third, Sustaiabl design component and management process. Historic resource are not only a cultural and spatial aspects but also it have potential importance in environmental aspects. Sustainable urbanism and architectural environment are cultural resource and it can be enhanced by long term established spatial orders. In order to keep the order, rehabilitation, reuse, remodeling of urban space should be managed by various participations which concerned with the city and urban architecture. That can be say systematic approach for the sustainable environment.

The fate of two cyclic ethers, THF(Tetrahydrofuran) and 1,4-Dioxane, in conventional biological wastewater treatment plants was investigated using sequential activated sludge process. Removal efficiency of THF were about 86% in average, which was greater than that of 1,4-Dioxane, 30%. However, it was not clear whether the removal of cyclic ethers in biological system was caused by microbial activity or not. Thus treatability tests were conducted by batch experiments. The effects of mixing, aeration and the addition of activated sludge on the removal of cyclic ethers were investigated in batch experiments. THF was totally removed by mixing and aeration in 24 hours while removal ratio of 1,4-Dioxane was at most 30% for the same period. This results could be ascribed to the differences in Henry's law constants between the two chemicals. In addition, biological degradation including biosorption was not obviously observed in these batch tests.

최근 서울 시민을 대상으로 한 설문조사에서 환경 문제 해결, 교통 체계 개선과 함께 범죄 예방에 관한 요구가 가장 높게 나타났다. 그 중에서도 가족과 함께하는 주거 지역의 범죄 예방에 대한 요구는 다른 어느 항목보다 더 중요한 것으로 나타났다. 범죄 발생률은 주로 노후화 된 주거 지역에서 높게 나타나는데, 이는 범죄와 물리적인 환경 요인의 관계를 나타내 주는 것이라 할 수 있고, 주변 환경에 대해 적절한 조치가 범죄를 예방할 수 있다는 것으로 이해될 수 있다. 각종 범죄로부터 안전할 수 있도록 하는 다양한 예방법이 있지만 우리 주변의 물리적인 환경을 개선함으로써 범죄를 사전에 차단하고 예방할 수 있다는 CPTED는 이러한 측면에서 가장 주목받고 있는 방법 중 하나이다. CPTED의 기본 원리는 자연감시, 접근통제, 영역성 확보의 기본 원리와 활동성 강화, 유지 관리의 부가 원리로 구성된다. 본 연구의 목적은 도심지 내 노후화 된 공동주택 단지를 대상으로 CPTED의 원리를 적용하여 범죄 발생률을 떨어뜨리고 사전에 예방할 수 있는 방안을 제시하는데 있다.

급격한 경제성장과 함께 도시의 인구 집중으로 주택 문제의 해결을 위해 대규모 아파트 단지가 들어섰고 현재도 그 수가 계속 증가하고 있다. 반면 경년이 오래 된 아파트의 경우 노후화로 인한 문제 해결을 위한 수단으로 정부차원에서 리모델링을 유도하는 정책에 의해 리모델링에 대한 관심이 높아지고 있으나 그에 따른 기술적 제도적 뒷받침이 부족한 형편이다. 리모델링의 성과를 객관적으로 평가할 수 있도록 리모델링의 특성과 사회적, 문화적 요구를 수용할 수 있는 리모델링 성능평가에 관한 연구가 필요하다. 본 논문에서는 국내 주택성능평가표시 제도와 일본의 기존주택 성능평가 항목을 비교하여 리모델링 공동주택의 성능평가를 적용하기 위한 방안에 대하여 연구하였다.

As environmental issues have been increased globally, eco-friendliness in the construction area, which accounts for more than 30% of total GHG gas emission has being urged. In response, the Korean government has implemented G-SEED(Green Standard for Energy and Environmental Design) certification from 2002. However, total number of certified apartment buildings is only around 1% of total number of approved apartment buildings. As a basic research to find out reasons of low rate of the certification, this paper analyzes consumers' decision-making process in G-SEED certified apartment building market comparing to non G-SEED certified one and draw System Dynamics modeling based on causal relationship. As a result, consumers' demand for the certified one is increased by 'Perceived Relative Utility' which is resulted from comparison process with non-certified one. The 'Perceived Relative Utility' is ascended upward steadily by 'Relative Perceived Price' considered as relatively short-term effect and 'Favorable Image of Certified Housing' referred to long-term effect.

Purpose - Since COVID-19, the government's expansion of liquidity to stimulate the economy has resulted in an increase in private debt and an increase in asset prices of such as real estate and stocks. The recent sharp rise of the US Federal fund rate and tapering by the Fed have led to a fast rise in domestic interest rates, putting a heavy burden on the Korean economy, where the level of household debt is very high. Excessive household debt might have negative effects on the economy, such as shrinking consumption, economic recession, and deepening economic inequality. Therefore, now more than ever, it is necessary to identify the causes of the increase in household debt. Design/methodology/approach - Main methodology is regression analysis. Dependent variable is household loans from depository institutions. Independent variables are consumer price index, unemployment rate, household loan interest rate, housing sales price index, and composite stock price index. The sample periods are from 2017 to May 2022, comprising 72 months of data. The comparative analysis period before and after COVID-19 is from January 2017 to December 2019 for the pre-COVID-19 period, and from Jan 2020 to December 2022 for the post-COVID-19 period. Findings - Looking at the results of the regression analysis for the entire period, it was found that increases in the consumer price index, unemployment rate, and household loan interest rates decrease household loans, while increases in the housing sales price index increase household loans. Research implications or Originality - Household loans of depository institutions are mainly made up of high-credit and high-income borrowers with good repayment ability, so the risk of the financial system is low. As household loans are closely linked to the real estate market, the risk of household loan defaults may increase if real estate prices fall sharply.

In recent years, the recipients of the services of the health centers in Korea have been shifted from individual sick persons to families as a unit. As a result, the home visiting care records which are all filled out manually, will be increased. Since there is virtually no increase in the number of community health nurses, the CHNs are required to work more efficiently. One of the ways to make the CHNs' work more efficient is to reduce recording time by using a computer. However, a computer system that can manage the families as a unit has not yet been developed. In response to this need, we developed a database system that can be utilized in home visiting care service. The family assessment data is collected. diagnosed. and evaluated according to the family diagnosis classification. The system for family diagnosis consists of seven areas. Those areas are family structure. maintenance of the family system, interaction and interchange. support. coping and adaptation, health management. and housing environment. The areas of the family diagnosis consists of 99 items in all. We expect the following from this system. First. the CHNs will be able to identify family problems more easily. Second. the community's health level can be confirmed by the statistics the system produces. Thirdly, the CHNs' nursing services will be cost effective via reduced recording time. Finally, the family problems of the sick individuals which have been neglected under the health system oriented on individual persons can be effectively managed.
