Developing countries are in competition to attract ODA and FDI in an effort to overcome poverty and development. This study tries to identify factors influencing the distribution of ODA and FDI resources and analyzes if ODA and FDI are in complementary relationship. We use a panel data for 53 African countries during early and middle of 2000 period. Factors affecting the ODA distribution include per capita GDP, physical infrastructure, good institutions of receiving countries. FDI was found to be positively affected by market size, trade openness, human capital accumulation, business-friendly regulatory environment. The impact of ODA is believed to be more effective and sustainable if it has a complementary relationship with FDI. Our result, however, did not confirmed the complementarity relation between the two.

The aim of this study was to enhance the value of the chestnut industry by analyzing the value chain structure. Based on the value chain theory, it is divided into primary activities and support activities. Thus, in total, 27 subjects from Gongju, Buyeo, and Cheongyang were interviewed and self-administered questionnaire. Regarding the value chain structure of the chestnut industry, the primary activities consisted of production followed by cultivation and storing, sorting and packaging, transportation and marketing sales. The support activities were divided into production infrastructure, policy, R&D, and systematization. The primary activities are able to maximize profits through cost reductions. The production was divided into general and environmentally friendly cultivation. Depending on the labor force, it is family-centered labor. However, the installation of harvest nets depends on a hired labor force (40 - 60%) such that it would be necessary to have a mechanized harvest to replace the manpower for the cost reduction. Transportation, marketing sales, and backdoor selling (38.1%) were higher than the existing channels (31.0%) using the National Agricultural Cooperative Federation. The enhancement of value could be created by maximizing profits through the reinforcement of the links between each subject. The production showed strong connections with cultivation/storing, sorting/packing, and backdoor selling and the National Forestry Cooperative Federation. The processing stage is a very simple structure, it would be necessary to have R&D and to support promotions, infrastructure, machines, and sales increases, which should be expanded by connections with other industries like the food industry.

Recently, there has been increasing interest in the use of rain garden systems as environmentally friendly ecological infrastructures for controlling stormwater runoff and managing non-point source pollution and information for the contamination of soil and plants can be essential for sustainable rain garden management. In this study, four rain garden mesocosms, namely single species planting with Rhododendron lateritium, single species planting with Zoysia japonica, mixed planting with R. lateritium and Z. japonica, and control without plants, were tested to investigate the change in concentrations of nutrients (N and P) and heavy metals (Cd, Cu, Pb, and Ni) in the soil and plants used in the rain garden system. The presence of plants resulted in greater nutrient retention in soil and lower potential leaching from the system. All systems showed an increase in the heavy metal concentrations in soil. The concentrations of most heavy metals were found to be higher in the herbaceous plants (Z. japonica) than in the shrubs (R. lateritium). The belowground part (root) had higher heavy metal concentrations than the aboveground part (leaf) but also showed a potential increase in leaves, and hence, careful plant management should be considered during rain garden operation.

The study aims to investigate differences between men and women in influence of various socio-demographic factors on choice of mode of transport. For this purpose, a binary logit model of choice probabilities is implemented on survey data of a developing country city. Results indicate women's choice of travel mode to be more environment-friendly than that of men. Well-educated, working and middle-aged individuals appear to be the most likely to choosing more-polluting modes of transport for frequent travelling purposes. Individuals in the sample who are the least socioeconomically well off are found the most likely to be promising for the environment. The findings of this study suggest the future transportation policies toward development of existing infrastructure of greener modes of transportation in the city such as, public transportation services and pedestrian lanes, so as to manage the rising issues of degrading environmental quality. The study highlights how the consideration and inclusion of socio-demographic factors is crucial for policy recommendation regarding curtailing the environmental damages contributed by transportation sector. Because mobility crucially affects all other indicators of empowerment, and women are the ones using green modes extensively, the city's transportation system should be so developed which gives their safety and security due importance.

The purpose of this paper is to offer policies or laws governing the future of Korean seafood markets in view of societal marketing concept. The environment surrounding those markets is changing quickly and constantly. The proposals in this paper are meant to help the Korean seafood market coping with this swiftly changing environment. This paper sorts this changing environment in terms of institutional side and secio-economical side. The institutional side involves the enforcement of international and domestic seafood trade standards, the increase of seafood importation, the adoption of optional seafood sales system, the openness of distribution market, and the adoption of TAC system. The secio-economical side involves the development of telecommunication and transportation, and the changing of seafood consumption pattern. The forecast about the future of seafood market could be classified into three fields, that is, the production field, the distribution field, and the consumption field of seafood. In the production field of seafood, the stabilization of supply of seafood and the production management oriented seafood market could be forecasted. In the distribution field, the formulating of enforced trade standards, the dispersion of marketing function among fisher, wholesaler and retailer, the development of marketing skills, and the promotion of marketing information system could be forecasted. Finally, in consumption field, the promotion of standardization and diversification, the appearance of intellectual consumers could be forecasted. This paper seeks to offer policies or laws fur the three categories of the seafood market-the government, the fisher, and the distributor-coping with the changing environment on the above three fields, thereby benefiting the consumer's long-term welfare. For the government, this paper suggests the construction of a Seafood Transaction Information Infrastructure, a Seafood Dealer License System, and a Seafood Safety Security System. For the fishers, this paper proposes an Eco-labelling System, a Sustainable Production System, and a Real Naming System in dealing seafood. Finally, for the distributors, this paper offers a Seafood Production Controlling System, a Nature-friendly Marketing System, and a Consumer-oriented Marketing System.

The cultural tendency based on sharing and cooperation, which has recently been a hot issue, accelerates throughout the world. This study began with a perception that a sharing culture is inherent in urban public spaces. This study aims to conduct a theoretical study of the sharing culture and to analyze the characteristics of the design composition of public spaces. This study selected squares in 16 European cities as cases for analysis. The results are summarized as follows:1)To analyze the design characteristics of public spaces in which a sharing culture is inherent, this study drew the shape and type of planes and sharing elements such as accessibility, symbolism and activity with the squares in the cases. 2)The shape of planes in the squares in the cases has been formed in close relations with the historic meaning and events of the area and the process of the construction of buildings surrounding the square. The squares in the cases were classified into seven plane types, and these squares have developmentally contributed to the formation of a sharing culture as a place for free participation and communication concerning social issues. 3)In the squares in the cases, the weight of road-centered access appears high, and in terms of the construction of human-friendly / environment-friendly infrastructure in the city or judging from the trend of the recent increase of pedestrian-centered plans for public space, it is judged that approaches with a high utilization rate of sidewalk or public transportation would be desirable. 4)Symbolic elements of the square become a device by which citizens can share the historic symbolism, along with artistic inspiration. In addition, by serving as an observatory from which people can take a view of the landscape of the city, it allows visual sharing of the entire city as well as the square. 5)A square is common pool resources in the community, and it is necessary to vitalize that in a direction of increasing the possibility of sharing, through the characteristics and methods of the composition of public design.
