  • Korea has maritime jurisdiction over an area 4.5 times larger than the nation's inland area, but negotiations with surrounding nations on the maritime boundary delimitation have still not been completed satisfactorily. In particular, maritime boundary delimitation has become an important issue in terms of maritime security and resource exploration. Considering national interests, the delimitation of the maritime boundary is essential. However, no system to help the decision-makers involved in maritime boundary delimitation has yet been systematically constructed. Therefore, the aim of this study was the development of a system to support such decision-making. In this study, considerations related to maritime boundary delimitation were investigated through expert advice and international precedents. Based on these considerations, data were collected from several organizations, and a spatial database was systematically constructed. Finally, MBDSS (maritime boundary delimitation support system) was developed to support maritime boundary delimitation. This GIS-based system provides visual information about the considerations for the maritime boundary delimitation. Thus, it could help decision-makers to choose appropriate boundaries during the negotiation. Furthermore, this system is expected to be utilized as a scientific tool on the delimitation of maritime boundaries.

  • Highly active and stable nano-sized Ni catalysts supported on MgO-$Al_2O_3$ calcined from hydrotalcite-like materials have been successfully developed with a strong metal to support interaction (SMSI) to enhance the coke resistance in combined $H_2O$ and $CO_2$ reforming of $CH_4$ (CSCRM) for syngas ($H_2$/CO=2) production. The change of the surface area and NiO crystallite size with varying the pre-calcination temperature of support and Mgo content was investigated in relation to the coke resistance. As increasing the pre-calcination temperature, the surface area decreases and the metal to support interaction becomes weak. As a consequence, the coke deposition was more severe on catalysts pre-calcined at high temperature. It was concluded that highly dispersed Ni metal in the surface of Ni/MgO-$Al_2O_3$ catalyst (MgO=30 wt%) pre-calcined at $800^{\circ}C$ had a strong metal to support interaction (SMSI) resulting in an increase of coke resistance and high activity.

  • Carbon nanofiber (CNF) grown catalytically was chemically activated with KOH to attain structural change of CNF. The structural changes of CNF through KOH activation were investigated by using BET and SEM. From the results of BET, it was found that KOH activation was effective to develop particular sizes of pores on the CNF surface, increasing the surface area of CNF. Activated CNF was applied as an anode catalyst support of fuel cell. The effects of different activation conditions including the activation temperature and the activation time on the specific surface area of the CNF activated with KOH were investigated to obtain appropriate structure as a catalyst support. The 60 wt% Pt-Ru catalyst prepared was observed by using TEM and XRD.

  • The purpose of this study is to evaluate farmer's general contents on the current direct payment schemes and to derive some improvement measures, based on the survey data for the three types of direct payment schemes currently executed in Korea; Rice Farmer's Income Support, Early Retirement Aged Farmer's Support and Less Favored Area Direct Payment. In recent years we have introduced diverse direct payment schemes that are expected to have immediate effects in a short term period without enough preparation of the policy, which raises some contradiction between the agricultural policy and the original purpose of the direct payments. The result shows some important revisions should be made related the direct payment schemes, such as farmer's income stability through the improvement of unit payment and the payment length jointed with criteria of the payment, in addition to keeping up multifunctionality of agriculture and enhancing the effect of structural adjustment in agriculture.

  • In France, the popularization of social rental housing development for regional balanced growth has encountered difficulties due to the increasing costs of housing development in the regions. As a new solution, since 2010, efforts have been made to promote participatory housing in the regions. As of 2023, Strasbourg has 284 households participating in the participatory housing projects. The Strasbourg area has many abandoned houses, and the land is owned by local governments. The local authorities are providing such lands for participatory housing and have established the "Eco-quartier" support association to efficiently support the project and assist in resident-led participatory housing development. This study analyzes the development characteristics of 26 completed participatory housing projects in the Strasbourg area and examines the initial development stages of the representative case, the "Ecologis" project. The success factors of the "Ecologis" project were the active administrative support of the local government, promotion for member recruitment, and the role of "Eco-quartier" in providing expert support teams. In the initial development stage, it identifies the distinctions from a similar concept in Korea, "community housing," and presents implications for the revitalization of participatory housing.

  • This study focused on individual differences in social support among older adults. The purposes of this study were to investigate sex and age group differences in social support and to examine the effects of intergenerational social support on life satisfaction among the rural elderly. Data were from 545 elderly over 60 years of age living separately from adult children in the rural area. With regard to sex differences in support exchanges, no significant differences were found in support-giving and support-receiving. Men reported giving more financial support to children than women, while women reported receiving more financial support from children than men. With regard to age group differences in support exchanges, there was less support-giving in older age group. Older parents in their 60s reported giving more financial, instrumental, and emotional support and receiving less financial support than the group of age 70+ Regression analyses showed that life satisfaction of both men and women was affected by support size and the frequency of contact with children. Giving financial and instrumental support was significantly associated with life satisfaction of men, but giving and receiving each type of social support had no effects on life satisfaction of women. Life satisfaction of parents in their 60s was found to be positively associated with support size, giving financial support and receiving emotional support, and negatively associated with giving instrumental support. In the group of age 70+, the frequency of contact with adult children and giving financial support had positive influences on life satisfaction.

  • Various government support policies are being promoted in order to stimulate growth of SMEs. The government is striving to provide effective support through direct methods of tax, finance and indirect methods through support programs. However, the view on the government's startup policy is still tense. We are sympathetic with the need for support, but discussions continue to be made on the effectiveness of support projects and support projects. Therefore, this study evaluates the importance and satisfaction of the government start-up support project. For this purpose, we conducted questionnaires on ICT start-ups who have experienced government start-up support projects. Of these, 128 were analyzed for GAP analysis and ISA. As a result of the GAP analysis of the government start - up support project, the degree of satisfaction (4.408) was lower than the degree of importance (5.221), confirming that the beneficiary's evaluation on the start-up support project was negative. As a result of the importance-satisfaction analysis, 'R&D' and 'commercialization' are located in the maintenance area, and 'government funding', 'marketing, overseas advancement' projects are included in the concentrated area. In the low-ranking areas, there are 'entrepreneur events and networks' items. Finally, there are 'facilities and spaces', 'mentoring and consulting', and 'entrepreneurship education' in the surplus areas. As a result of multiple regression analysis, it was found that 'R&D', 'entrepreneurial education', and 'government funding' influenced satisfaction. Based on the results of this study, it is expected that it will contribute to improving the quality level of the government start-up support project by establishing the support policy for the ICT start-up enterprises and improving the system.
