안정적인 전력 공급은 해당 지역의 생활수준 개선과 소득 수준에 중요한 역할을 하기 때문에, 공적개발원조 (Official Development Assistance, 이하 ODA)의 중요한 목표중에 하나이다. 하지만 수많은 개도국의 교외지역은 국가 전력망과 제대로 연결되지 못하여 전력을 전혀 공급 받지 못하고 있고, 국가 전력망과 연결된 일부 받는 지역도 전력 용량의 한계로 인해 수시로 정전이 일어나고 있는 상황이며, 이는 해당 지역의 소득 수준 향상과 생활수준 개선에 큰 장애요소로써 작용하고 있다. 서울대학교가 넬슨-만델라 아프리카 과학기술원 (Nelson-Mandela African Institution of Science and Technolgoy, 이하 NM-AIST)과 협력하여 건립된 한국-탄자니아 적정기술거점센터 (Korea-Tanzania Innovative Technology and Energy Center, 이하 iTEC)은 이러한 문제를 해결하기 위해, 전력이 공급되지 않는 탄자니아 교외지역에 스마트-독립전력망을 활용한 소규모 태양광 발전소를 건설하고, 이와 연계된 사업을 진행함으로써, 이러한 문제를 해결하고자 한다. 이를 위해 킬리만자로 (Kilimanajaro) 주 음카라마 (Mkalama) 마을과 아루샤 (Arusha) 주 응구르도토(Ngurdoto) 마을에 각각 10 kW, 7 kW급 태양광 발전소를 건설하여, 각각 50 여가구에 전력을 공급하고 있다. 또한, 이에 대한 데이터를 수집하고 발전소와 배전 시스템의 운영을 위해 스마트 모니터링 시스템을 설치하였다. 이를 통해 고장 진단, 사용량 측정 등 다양한 기능을 수행하고 있다. ITEC에서는 이러한 스마트-독립전력망을 활용한 소규모 태양광 발전소 건설과 전력 공급, 그리고 다양한 연계사업 진행을 통해 지속가능한 개발도상국 농촌 주민의 소득수준과 삶의 질 향상을 도모하고 있다.

It is certain that urbanization has transformed the ecological consequences severely, but urban ecosystem is not fully understood yet. Urban growth is not like a static form and it spreads spatially and temporally. Therefore in studying urban ecosystem, it is important to relate the spatial pattern of urbanization to ecological processes. Using gradient analysis, we attempted to quantify the urbanization's spatial impacts in Daejeon-city and Cheonan-city, Chungcheong-province, Korea. Because of Multifunctional Administrative City Planning (MACP), a lot of development projects are planned in Chungcheong-province, Korea. It's important to study about original cities' patterns and impacts. These results can be adopted to future city planning. So several measures such as fragmentation, vegetation index, surface temperature, population density, and income rate were computed along a 75km long and 3km wide transect. The results showed that Daejeon-city has a wider urban center, lower vegetation indexes, and higher surface temperature than Cheonan-city. Therefore in the perspective of urban environments and sustainable urbanism, it seems that Cheonan-city is better than Daejeon-city. The changes along the transect have important ecological implications, and quantifying the urbanization gradient is an important step in understanding urban ecology.

Rapid urbanization has transformed the spatial pattern of urban land use or cover. This paper concentrates that changed characteristics of landscape structure in the Tancheon Watershed, from 1995 to 2003 were investigated using land cover map. We used FRAGSTATS software to calculate landscape indices to characterize the landscape structure. We found that built up area has been increased rapidly during the study period, while cultivated area and forest area have been decreased rapidly in the same period. From 1995 to 2003, built up area was increased from 19.73% to 39.62% and cultivated area and forest area was decreased 17.60% to 5.97% and 58.31% to 49.41%. Number of patches, mean euclidean nearest-neighbor distance, contagion index, Shannon's diversity index increased considerably from 1995 to 2003, also suggesting the landscape in the study area became more fragmented and heterogeneous. but because of continuously fragmentation, landscape became homogeneity. The study demonstrates that landscape metrics can be a useful indicator in landscape monitoring and landscape assessment.

This paper proposes and examines the economic impact of infrastructure improvement on the San-En-Nanshin region in the Chubu area of Japan. We develop a single transportation computable general equilibrium (CGE) model for each subregion within the San-En-Nanshin region. The explicit modeling of the transportation infrastructure is defined based on interregional commuting flows and business trips, considering the spatial structure of the San-En-Nanshin economy. A CGE model is integrated with an interregional transportation network model to enhance the framework's potential for understanding the infrastructure's role in regional development. To evaluate the economic impact of transportation improvement, we analyze the interrelationship between travel time savings and regional output and income. The economic impact analysis under the CGE framework reveals how transportation facilities and systems affect firm and household behavior and therefore induce changes in the production and consumption of commodities and transportation services. The proposed theoretical model was tested by using data from the 2005 IO tables of each subregion and the 2006 transport flow dataset issued by the Ministry of Land, Infrastructure, Transport, and Tourism in Japan. As a result, the paper confirms the positive effect of transportation investment on the total output and income of the studied region. Specifically, we found that while economic benefits typically appear in urban areas, rural areas can still potentially benefit from transportation improvement projects.

This study analyzed farmers' and experts' perceptions of the Agricultural Income Survey (AIS) conducted by the Rural Development Administration and estimated its socioeconomic value. The research surveyed 104 farmers in Gyeongsangbuk-do and Jeollanam-do. To estimate the AIS's socioeconomic value, this study examined public information projects in the field of agriculture and public information, proposing an estimation methodology based on prior research. The socioeconomic value of the AIS was calculated in three stages (information generation, collection and analysis, and utilization) using the replacement cost and contingent valuation methods. In 2020, the estimated socioeconomic value of the AIS ranged from a minimum of KRW 631.2 billion to a maximum of KRW 799.1 billion per year. To improve the socioeconomic value of the AIS, it is important to booster awareness, expand sample sizes for more reliable data, increase manpower and budget, refine survey questions, and enhance analyzing capabilities. And it's crucial to foster cooperation with surveyed farms, promote collaboration among investigative agencies, improve investigator skills, and strengthen management capabilities to facilitate information dissemination.

Purpose - Domestic cooperatives tend to increase during the establishment of cooperatives and gradually through the basic law of social needs. However, only cooperatives' qualitative grow this secured without blessings, and their quantitative growth through government support is questionable. The purpose of this study is to analyze the agricultural cooperatives established through the Distribution System Cooperatives Basic Law, which was enacted in January 2012. Subsequently, establishing agricultural cooperatives was done briskly. However, cooperatives established rapidly after the founding of the Basic Law encountered problems. Research design, data, and methodology - To assess the performance of selected agricultural cooperatives, data were analyzed using the methodological Analytic Hierarchy Process (AHP) approach. The AHP is a set of systematic procedures to hierarchically analyze the elements of any problem. Using a survey on expertise, a series of comparative determinations of each pair is performed to evaluate the relative strengths and the strengths of the impact between elements within the hierarchy. A survey was conducted on 10 small agricultural cooperatives using AHP analysis for the examination. The purpose of such research and analysis is to recommend a direction for future policies aimed at small agricultural cooperatives. Result - This study applied three types of policy evaluation criterion, including market expansions, organizations, and cooperative projects, and 12 types of small agricultural cooperative policy measures. Market expansion policies for agricultural cooperatives are classified into four categories: school meals, direct transactions, shopping malls, and wholesale markets. Organizational policies for agricultural cooperatives are classified into four types: existing sales channel management, education, preventing free riding, and enlarging members. Cooperative project policies in agricultural cooperatives are classified into four policy areas: cooperation between cooperatives, community contribution, joint businesses, and government links. In this paper, the growth priority in agricultural cooperative policies is analyzed by applying policy evaluation criteria on the basis of a survey on expertise. The priorities of the policy program are also analyzed using a decision analytic hierarchy process. The results indicate that market expansion is the most important policy evaluation criterion therefore, improving direct transactions, school meals, management of existing sales channels, and shopping malls are crucial policy measures. In contrast, the cooperation of cooperatives, expansion of union members, and cooperation with the government were found to have low priority. Conclusions - Agricultural cooperatives should develop plans as follows. Small agricultural cooperatives need to secure school meals and direct transactions for market expansion, restructure marketing strategies to manage existing sales channels, and, finally, increase education and training for sustainable organizational development. This study has the following limitations. Because the subject of the investigation is a new cooperative, determining its sustainable growth is difficult. Therefore, through analysis and a continuous study of cooperatives, future research is expected to show that modifying the direction of agriculture cooperatives is necessary.

As the "Guidelines for GHG Environmental Assessment" was revised, it pointed out that the developers should evaluate GHG sequestration and storage of the developing site. However, the current guidelines only taking into account the quantitative reduction lost within the development site, and did not consider the qualitative decrease in the carbon sequestration capacity of forest edge produced by developments. In order to assess the quantitative and qualitative effects of vegetation carbon uptake, the CASA-NPP model and satellite image spatial-temporal fusion were used to estimate the annual net primary production in 2005 and 2015. The development projects between 2006 and 2014 were examined for evaluate quantitative changes in development site and qualitative changes in surroundings by development types. The RMSE value of the satellite image fusion results is less than 0.1 and approaches 0, and the correlation coefficient is more than 0.6, which shows relatively high prediction accuracy. The NPP estimation results range from 0 to $1335.53g\;C/m^2$ year before development and from 0 to $1333.77g\;C/m^2$ year after development. As a result of analyzing NPP reduction amount within the development area by type of forest development, the difference is not significant by type of development but it shows the lowest change in the sports facilities development. It was also found that the vegetation was most affected by the edge vegetation of industrial development. This suggests that the industrial development causes additional development in the surrounding area and indirectly influences the carbon sequestration function of edge vegetaion due to the increase of the edge and influx of disturbed species. The NPP calculation method and results presented in this study can be applied to quantitative and qualitative impact assessment of before and after development, and it can be applied to policies related to greenhouse gas in environmental impact assessment.

본 연구는 아프리카 지역의 농업기술보급체계를 진단하고, 보급체계의 발전방향 및 개발원조 전략을 제시함으로써 ODA(Official Development Assistance)를 통한 아프리카 농업기술전수의 효과성 제고에 기여하고자 한다. 기존의 대(對)아프리카 농업원조는 아프리카의 농업이 내포하고 있는 '다양성'과 '복잡성'의 가치를 간과한 채 진행되어 왔으며, 막대한 원조금액의 기대와 달리, 아프리카의 농업발전은 답보 상태에 놓여 있다. 본 연구는 농업기술보급체계 및 ODA사업 전략의 아프리카화(Africanization) 논의를 제기하고 있으며, 설문조사 일변도의 미시적 시각에서 나아가 사례국가별 농업기술보급체계의 거시적 특성을 분석하고 있다. 연구 결과, 사례국가의 기술보급체계는 조직과 기능에 따라 상이한 특성을 지니고 있으며, 이에 기술보급체계의 주체별 역할 세분화와 기능별 역량 분석 내용 또한 차별적으로 구성되었다. 에티오피아의 경우, 정부조직의 규모별로 하향식 농업기술보급체계가 구축되어 있으며, 전달체계의 최종행위자인 농민집단의 참여가 확대되고 있다. 그러나 여전히 기술전달을 통한 생산성 향상 등의 기능보다는 농가경영적인 측면에 치중되어 있어, 전달 기술의 효과적인 활용이 결여되어 있는 실정이다. 반면 우간다의 사례에서는 전 기관을 포괄하는 참여적 지도체계가 구축되어 있으나, 기술지도의 시급성에도 불구하고 지도 역할보다는 연구 기능의 확대에 투자가 집중되어 있음이 규명되었다. 상기 연구결과는 현 농업기술보급체계의 개선과 이를 토대로 한 농업기술전수사업의 수행이 아프리카 농업 농촌 ODA사업의 효과성 제고와 농업침체의 문제를 해결하기 위한 필요조건임을 논증하고 있다.

Korea has experienced serious changes during the last several decades of industrialization. Limited land resources and excessive rural-to-urban migration inevitably resulted high-rise apartment housing development. However, apartment housing couldn't follow up social change and residents' needs. Turning into the 21st century, there are great demands for the diversification of housing style and amenity of housing, which include enhancing community lift through proper collective environment. To solve these problems, cohousing has been introduced in Scandinavian countries. A primary goal of cohousing is the desire of residents to live in a socially supportive setting. People can do housework together and also can promote active mutual relationship among residents in the community. Physical feature of cohousing, in combination with social organization factors, may serve to enhance or support the sense of community sought by residents. In this point of view, the purpose of this study is to find out the physical feature of cohousing in Denmark and Sweden. First, it is to figure out the background and development of cohousing in Denmark and Sweden. Then, by making clear physical features between similarity and difference of two countries of cohousing through case study; such as housing type, the circulation patterns, common facilities and etc. This paper could suggest a possibility of application of cohousing in Korea to present how they encourage emphasize design aspects that increase the possibilities for social contacts and the sense of community. Also, it goes on to suggest that the educational program and the support from the government.
