일본 신도시는 1980년대 후반 자족성 강화를 위한 복합다기능화 정책이 추진되었음에도 불구하고 최근 초기개발지구를 대상으로 급격한 고령화와 시설 노후화에 따른 도시쇠퇴 문제가 대두되고, 이에따라 비영리법인을 중심으로 도시재생활동이 추진되고 있다. 아울러, 사업이 진행중인 지구는 택지처분 지난에 따른 낮은 인구정착율 문제가 지적되고 있다. 과연 이러한 현상이 신도시의 일반적인 문제이며, 일본 신도시의 복합다기능화 정책은 실패한 것일까? 신도시의 지속가능성을 위하여 어떠한 정책이 유효할 것인가? 이 점에 착안하여 본 연구는 자족성과 소셜믹스를 중심으로 동경권 대규모 신도시의 지속가능성을 고찰하였다. 본 연구를 통하여 본 동경권 신도시는 일부 쇠퇴지역이 존재하나 전체적으로는 타지역에 비하여 고령화율이 낮고, 인구가 증가하고 있음을 알 수 있었다. 하지만, 자족성지수로 살펴본 신도시는 자족성이 점차적으로 증가하고 있음에도 불구하고 주변교외지역 보다 높다고 보기 어려워 신도시 자체의 복합다기능화 정책의 한계가 나타났다. 또한, 신도시의 소셜믹스 평가결과 연령과 직업분포 등의 다양성이 낮게 나타났으며, 지구레벨의 다양성 분석결과 주택의 형태와 소유관계가 거주민의 연령과 직업의 편중에 영향이 있었다. 이러한 분석결과를 토대로 본 연구는 신도시의 지속가능성을 높이기 위하여는 도심 접근성, 주변산업과의 연계성을 고려한 입지선택이 매우 중요하며, 계획단계에서 거주민의 다양성을 증가시킬 수 있는 소셜믹스 계획이 필요하다고 판단하였다.

본 연구에서는 Value Engineering 기법을 토취장 선정의 도구로 활용할 수 있는지의 여부를 검토하였다. 이를 위해 대규모 택지개발지역의 토취장 후보지들에 대한 지반조사 결과를 분석한 후 토취장 후보지들의 가채량을 산정하였으며, 토취장 후보지들의 VE 평가에는 가중치 부여 매트릭스평가법을 적용하였다. VE 평가를 위해 평가항목을 결정한 후 중요도를 산정하고 평가척도를 설정하였으며, 토취장 후보지에 대한 성능등급 및 성능평가를 수행하여 토취장 후보지들의 개발 우선순위를 결정하였다. 결과적으로 토취장 후보지들에 대한 상대공사비는 운반거리와 밀접한 관련이 있으며, 운반거리가 멀어질수록 상대공사비는 점차 증가하므로 운반거리가 토취장 선정에 있어 상당한 영향을 미친다는 것을 확인하였다. 또한 최적의 토취장 후보지를 선정하는데 있어 토취장 자체의 조건도 중요하지만, 생애주기비용의 영향을 무시할 수 없는 것으로 나타났다.

Urbanization has led to extreme changes in land use on urban watersheds. Most cities are becoming residential, commercial and industrial areas, making infiltration and storage of rainfall less favorable. The demand for LID (Low Impact Development) technology is increasing in order to mitigate this water cycle distortion and return to existing hydrological conditions. The LID technique is effective in reducing runoff by permeating the urban impervious area. However, considering the limit of the installation area and the financial requirement of the installation, there is not much research on the linkage of each LID component technology for optimum efficiency according to the appropriate scale. In this study, the effects of the LID facilities applied to the target site were simulated using the SWMM model, suggesting the optimal linkage method considering interconnectivity, and applying the effects as an existing installation of individual facilities. The water balance at the time of application of the LID technology, short-term and long-term rainfall event were compared. Also, the individual application and the linkage application were compared with each other. If each component technology has sufficient processing size, then linkage application is more effective than individual application.

A/R CDM(Afforestation/Reforestation Clean Development Mechanism) in Kyoto Mechanism means, either afforestation in the area used for other purposes more than 50 years or reforestation in the area used for other purposes on December 31st in 1989. South Korea has few sites due to the successful forestation in the past, but North Korea has not reforested the deforested lands since the mid-1970's. So these areas need to apply A/R CDM Project for restoration. The purposes of this study are to make a time series analysis in deforested areas and to estimate a feasibility of A/R CDM. To find the site satisfying A/R CDM business definition, land cover classification was applied using satellite images of the mid-1970's with good forestation, late 1980's including A/R CDM base year, and recent 2000's, and the chronological change was analyzed to categorize the possible sites. The North Korean topographical map of 1977 was used to verify land cover classification degree of 1970's, the land cover classification results made by the Ministry of Environment in 2000 were compared to verify the accuracy of 1980's results, and the land cover classification results in 2000's were verified by 2 site visits. The results of this study can be summarized as follows. The eligible A/R CDM sites are 605,156ha on the basis of the forestation change analysis in North Korea. Since the mid-1970's, 30.8% of the decreased forestation area of 1,966,306ha was classified into A/R CDM eligible sites. While other countries have the limited eligible sites, which has not been used for forestation since 1989 or which is being scattered, North Korea has large scale sites. Deforested sites are mainly around road and residential area, consequently give better accessibility for forestation than other countries. In conclusion, it is found that North Korea can provide efficient site for applying A/R COM Project to forestation restoring deforested land because of easy accessibility and existence of many possible sites due to artificial deforestation. Also, it is meaningful that the study suggests the application possibility of A/R COM Project to restore deforested land in North Korea and the related basic information through the chronological classification of the mid-1970's with good forestation, the late-1980's including A/R COM base year, and recent 2000's. It is expected that the study contributes to revitalization of A/R CDM Project and related research on North Korea forestation.

With the development of the internet and the spread of 'digital home', apartment houses equipped with the homepages connecting apartment houses as one cyberspace unit have increased. The virtual community with a homepage in apartment complex have improved the effect on management businesses in the side of a apartment manager and increased the importance of the space with a strong tie between residents in the side of residents. But the apartment residents didn't make full use of the virtual community because they have the low level of recognition of it. Therefore, this study attempted to present basic materials for the scheme to revitalize the virtual community. For this purpose, it attempted to find residents' recognition of and participation in the virtual community and demand for the classified contents conducted before this study. In the research method, it conducted the questionnaire research. The results are as follows. 1) First of all, It was found that the apartment residents had the low level of recognition of the virtual community. There was a significant difference according to the degree and the level of using the internet. Some easy-access programs are necessary. 2) The apartment residents took part in the virtual community about 67 percents because there was a lack of the public relation of the virtual community. 3) It was found that there was a significant positive correlation between the level of recognition and participation. 4) An attempt was made to identify the apartment residents' demand for the type of virtual community contents. It was found that most of contents were needed. 'apartment complex introduction and management information' showed the highest score among them. 5) Most respondents are affirmative to the virtual community. Therefore the residential community could be reinforced if the contents of virtual community is developed and well operated in the future.

Objectives This study examined the spatial distribution and the extent of soil contamination by heavy metals resulting from primitive, unconventional informal electronic waste recycling in the Agbogbloshie e-waste processing site (AEPS) in Ghana. Methods A total of 132 samples were collected at 100 m intervals, with a handheld global position system used in taking the location data of the soil sample points. Observing all procedural and quality assurance measures, the samples were analyzed for barium (Ba), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb), and zinc (Zn), using X-ray fluorescence. Using environmental risk indices of contamination factor and degree of contamination ($C_{deg}$), we analyzed the individual contribution of each heavy metal contamination and the overall $C_{deg}$. We further used geostatistical techniques of spatial autocorrelation and variability to examine spatial distribution and extent of heavy metal contamination. Results Results from soil analysis showed that heavy metal concentrations were significantly higher than the Canadian Environmental Protection Agency and Dutch environmental standards. In an increasing order, Pb>Cd>Hg>Cu>Zn>Cr>Co>Ba>Ni contributed significantly to the overall $C_{deg}$. Contamination was highest in the main working areas of burning and dismantling sites, indicating the influence of recycling activities. Geostatistical analysis also revealed that heavy metal contamination spreads beyond the main working areas to residential, recreational, farming, and commercial areas. Conclusions Our results show that the studied heavy metals are ubiquitous within AEPS and the significantly high concentration of these metals reflect the contamination factor and $C_{deg}$, indicating soil contamination in AEPS with the nine heavy metals studied.

Recently, there has been the gradual growth of the public in rural amenities, hobby farming works, much more urbanities, and especially near-retires. However, in spite of popular preference to ruralities, little has been known about their demand on retired rural life. Therefore, this study examined urbanites' attitude to preparatory works for out-migration, preferred residential site condition and life styles in the countryside. For the purpose, data were collected from the survey with the sample of 62 urban trainees who were studying farming technology in department of training on agricultural technology of Korea National Agricultural College, RDA. We carried out the experience farming to candidate with using the abandoned sericultural facilities which are the silkworm rearing house and mulberry fields. The 71% of urban trainees, who answered in this survey, hoped to move into countryside after retirement and to make a monthly income of $1,000 from agriculture. The age distribution of sericulural farmers is about 79% more than that of 60 years old. In the experience farming works. The two candidates made 1,977$ with net income through 32 days worked in spring season. In autumn season, the couple candidates made 1,317$ with net income through 23 days worked. Knowledge of these results will be important to policy-makers and to understand the role that retirement in-migration play in stimulating economic growth of rural agricultural farmers.

This study examines the preliminary license and approval facilitation standards for improvements in quality for childcare centers focusing on the number of children, building space standards, facilities and equipment, and childcare program. Data from 48 caese was collected from childcare centers nationwide in Korea through a questionnaire and building plan. The first step for starting care licensing is to work out the ages and numbers of children within four or five age ranges. The second step is to work out the number of children as small, medium, or large considering staff to child ratios and building size. The Nnext step is to make a choice about childcare service quality classification as minimum, fair, or good, considering space requirements per child for the building, the classroom and the outdoor playground. The next step is to make a choice of space organization relating to service programs, considering the sleeping and eating area, indoor play area, toilet & washing facilities, classroom layouts such as cluster type, double zone type, single zone type, and others. Also, each room and entrance, office, kitchen, storage, laundry, teacher's area, and chilldren's area, need to be checked for space requirements and performances. The last step is to arrange the childcare program with the building and site plan. In conclusion childcare service quality will get better by upgrading of license regulation especially in minimum space requirements per child, corresponding with an increase in GNP and housing area per person. This is needed for childcare licensing in order to determine the quality level of childcare service.
