$^{18}F$-fludeoxyglucose PET (FDG-PET) can help finding an abnormal metabolic activity in brain. In this study, we evaluated an efficiency of volume- and cortical surface-based analysis which were used to determine whether standardized uptake value ratio (SUVR) of FDG-PET was different among Alzheimer's disease (AD), mild cognitive impairment (MCI), and healthy control (HC). Each PET image was rigidly co-registered to the corresponding magnetic resonance imaging (MRI) using mutual information. All voxels of the co-registered PET images were divided by the mean FDG uptake of the cerebellum cortex which was thresholded by partial volume effect (>0.9). Also, the SUVR value of each vertex was linearly interpolated from volumetric SUVR image which was thresholded by gray matter partial volume effect (>0.1). Lobar mean values were calculated from both volume- and cortical surface-based SUVRs. Statistical analysis was conducted to compare two measures for AD, MCI and HC groups. Even though the results of volume (SUVR_vol) and cortical surface-based SUVR (SUVR_surf) analysis were not significantly different from each other, the latter would be better for detecting group differences in SUVR of PET.

Community Building("Machizukuri") which was quickened in Japan from the end of 1960's, relating to paradigm shift in urban planning mainly aims at safe and comfortable life in community. It is related to a continuous theme on making a guideline to desirable community reflecting historical and spatial characteristics of each region and needs of citizens, breaking away from uniform or authoritative planning. The purpose of this study is to establish roles of participants in Community Building, which is foundation for participatory Community Building to be a new guideline for urban policy, planning and administration as a major subject of local governments, and for a nation wide movement of citizens themselves. For the purpose a practical concept of Community Building is primarily made from analytical review of preceding studies and cases, and relationship between Community Building and general urban planning is involved. Secondly the analysis of problems which are exposed in the cases in Korea and Japan and the classification based on characteristics of various movements are followed. Each case is especially analyzed in two aspects, that are factors(institutional, financial and educational factors) and results(causes and limits of success). And these results are examined and proved by means of survey. Through the above this study concludes to a practical system for implementation of participatory and comprehensive approach to Community Building, including institution design, financial and educational methods.

The purpose of this study is to investigate the housing satisfaction and preference of housing management for residents and staffs. The data used in this research are collected from survey of 100 housing management staffs and 190 residents of public rental housing. Analysis of questionnaire research was utilized SPSS WIN 12.0 Korean version program in analyzing data. And Frequency, Means and T-Test of analysis were enforced to verify differences of recognition between staffs and residents. Results, ① Facilities maintenance, operations, cleaning, housing costs only in direct residential satisfaction was high. ② Residents and Staff survey, four items(Public facilities, Personal space, Tenant management, Payment Management) were preferred in direct management. Major finding of this study are as follows; ① Housing management system should be changed provider focused mainly on the consumer to change. ② Housing manager should enhance the accessibility and responsiveness ③ Housing manager should improve management expertise ④ Housing manager should increase reuse and word-of-mouth effect.
업무시설 친환경건축에 있어서 공간체험에 관한 연구 -매개공간에 있어 친환경건축의 공간성 및 공간체험을 중심으로

The architectural space is the involuntary place where man lives and experiences, and as a 3 dimensional space through the continuous experience with the concept of 4th dimension of time, it provides the observers with the dramatic space imagery. These kinds of space experiences are experienced mentally and perceptively through the physical elements of inner and outer space of the architectural buildings, and this space imagery is created here by all the space composing elemensts of the building. These space experiences are caused by the changing processes of the space characteristics, and the observers perceive the changes in space characteristics. The present building is going with Eco-Architecture. When 2008 sees the building,,Eco-Architecture design which hits appears .There is a possibility of seeing 16 kind types from that place. And From here examined the spatiality which is expressed. These changing processes of inner and outer space, space versus space, and unit space, which are perceived by the observer. It`s way to help in architectural design and wishes.

건축공간에서 인간은 생활하고 그에 따라 다양한 체험·경험을 한다. 이 공간은 3차원적으로 구성된 공간으로 4차원적인 시간 개념과 함께 이동에 따른 연속적인 경험을 통해 인간은 극적인 공간감을 체험한다. 특히 이 체험은 도시와 건물, 인간의 접하는 매개공간에서 아주 활성화되는 것이다. 따라서 본 연구는 이러한 기본 개념에 따라 매개공간에서 보이는 친환경 설계 사례를 들고 이곳에서 표현되는 공간성의 심리적 요소의 변화와 건축물에 사용된 수법, 공간성 요소의 관계를 파악, 공간성 변화를 일으키는 주된 논제에 대한 분석을 보여주는 것으로 한다.

도심 밀집시가지에서 마을 만들기 수법적용에 관한 제안 -인천시 동구 만석동(아카시아 촌)을 사례로-

밀집시가지는 오래된 주거지가 밀집되어 있기 때문에 도로가 좁으며, 공원도 부족하여 방재 측면과 주거 환경 등 여러 가지 문제를 안고 있다. 또한 법적인 규칙을 동반하지 않은 지구에서는 지구전체에 정비개선의 효과가 나타나기까지는 긴 시간이 필요하다. 이에 따라, 밀집시가지의 정비개선은 주민·전문가·행정의 협동과 참여의 지침이 되는 마을 만들기의 수법을 적용할 필요성이 있다. 본 연구는 밀집시가지에서 거주자가 풍요로운 생활을 하고, 커뮤니티를 유지 향상 시키는 마을 만들기 수법으로 소규모의 지속적인 계획적 방법론에 대해 인천광역시에 소재하는 아카사키 촌을 대상으로 마을 만들기 수법 적용방안을 검토하는 것을 목적으로 한다. The built-up areas crowded with old housing lots have many problems in the aspect of disaster protection and residential environment such as narrow roads and insufficient parks. Out of these massed areas some districts prove fruitfulness in improvement and strengthening urban infrastructure by means of land replotting or residential redevelopment, while it takes longer time to be effective in the districts not prescribed by law, With regard to this situation there are needs for the application of Community Planning method to advance by easy stages of betterment and to build a livable place where the inhabitants including the aged live with a sense of relief and security. The method is also anticipated to be guidelines for the participation and governance of residents, professionals, and administrations. This study aims to seek a better application of the Community Planning to Akasaki village in Inchon-city as the sustainable and systematic ways to affluent life and desirable community on a small scale.

Skeptical responses to urban design based on the Physical Planning theory assuming the existence of social agreement and the absolute authorities of planners bring about alternatives such as Participatory Planning and Community Design derived from Harbermas' Communicative Rationality. But the normative contentions do not progress any more to the stage of presenting practical strategies. This is the cause why there should be systematic approaches to reveal the relationships among various concepts or variables. With regard to the Community Design this study intends to take a statistical approach to find relationship between project scale and its accomplishment. The hypothesis that the smaller scale of project begets the better outcomes was tested to be rejected as a result of the analysis of variance. But the result also shows that appropriate density in relatively large area makes residents' expected satisfaction high. Although this discovery has its own meaning the tryout is anticipated to laying the cornerstone of quantitative analyses in the following studies.
