MOTIE(Ministry of Trade, Industry & Energy) aims to build a Southwest 2.5GW offshore wind farm. The job will require help from the government, electric operator and manufacturers. The domestic offshore wind farm market will boost global competitiveness up until 2019. This research analyzes the economic impact of the offshore wind farm project. The local acceptance in terms of production, employment and value added are expected to be maximized. According to the quantitative analysis using the extended 2010 input-output table, we calculated that the production inducement impact will reach up to 13.5 trillion won. 11.07 trillion won from the offshore wind farm industry and 2.4 trillion won from others. Furthermore the impact of increase in employment is expected to reach 22,662. 9,883 will be from the wind farm industry and 12,779 from other fields. The impact is expected to be greater especially during the middle of the jobless growth period, Lastly, the value added inducement impact is expected to be 4.24 trillion won. Regarding economic impacts, strategies required for increasing local acceptance are as follows. First, in order to diversify and sophisticate the primary industry into a secondary or tertiary one, we need to develop the nearby wind farm site into a wind farm thema park. Attracting the wind farm production, installing and maintaining/repairing firms and establishing an experience center for K-12 students by providing them an education center for offshore wind energy can be specific means of development. Also, during the operation and after the destruction of facilities, the government should lay out the sub-structure of the wind farm as a sea ranch. Thirdly, the level of local acceptance regarding the community ownership of the offshore wind farm should increase to those of Middelgrunden(Denmark) and Navarra(Spain). Considering the economic condition of Buan, Gochang and the Yeonggwang area, community ownership is one of best solutions for the increment of local tax revenue. At last, considering the supports system of areas adjacent to power plants and ``Partnership management with local community’, the offshore wind farm operator may need to provide assistant policies to nearby communities. The policies should be based on Corporate Social Responsibility(CSR) such as education scholarship projects, local economy cooperative projects, sports/culture projects.

The 'Mobile Science Lab' is a public program designed to bring teenagers to be engaged in the activities of science and technology. In this study, we attended to elementary school students' participating actions in the program and intended to understand their enjoyment of science from sociocultural and practical perspectives. By drawing on case materials culled from our database, we articulated the features of the enjoyable science activities in the form of two major claims. First, students had rich opportunities to communicate emotionality, which therefore grounds emerging actions on the positive emotional valence. Second, ongoing actions opened up new action possibilities not only to the actors themselves, but also to other community members. The results of this study constitute theoretical frameworks for understanding enjoyment without dichotomizing emotion and cognition, and thereby contribute to designing enjoyable activities of learning science.

The stabilized all-solid-state battery structure indicate a fundamental alternative to the development of next-generation energy storage devices. Existing liquid electrolyte structures severely limit battery stability, creating safety concerns due to the growth of Li dendrites during rapid charge/discharge cycles. In this study, a low-dimensional graphene quantum dot layer structure was applied to demonstrate stable operating characteristics based on Li+ ion conductivity and excellent electrochemical performance. Transmission electron microscopy analysis was performed to elucidate the microstructure at the interface. The low-dimensional structure of GQD-based solid electrolytes has provided an important strategy for stable scalable solid-state lithium battery applications at room temperature. This study indicates that the low-dimensional carbon structure of Li-GQDs can be an effective approach for the stabilization of solid-state Li matrix architectures.

The core-shell InGaN/GaN Multi Quantum Well-Nanowires (MQW-NWs) that were selectively grown on oxide templates with perfectly circular hole patterns were highly crystalline and were shaped as high-aspect-ratio pyramids with semi-polar facets, indicating hexagonal symmetry. The formation of the InGaN active layer was characterized at its various locations for two types of the substrates, one containing defect-free MQW-NWs with GQDs and the other containing MQW-NWs with defects by using HRTEM. The TEM of the defect-free NW showed a typical diode behavior, much larger than that of the NW with defects, resulting in stronger EL from the former device, which holds promise for the realization of high-performance nonpolar core-shell InGaN/GaN MQW-NW substrates. These results suggest that well-defined nonpolar InGaN/GaN MQW-NWs can be utilized for the realization of high-performance LEDs.

A composite active layer was designed based on graphene quantum dots, which is a low-dimensional structure, and a heterogeneous active layer of graphene quantum dots was applied to the interfacial defect structure to overcome the limitations. Increasing to 1.5~3.5 wt % PVP GQD, Vf changed from 2.16 ~ 2.72 V. When negative deflection is applied to the lower electrode, electrons travel through the HfOx/ITO interface. The Al + ions are reduced and the device dominates at low resistance. In addition, as the PVP GQD concentration increased, the depth of the interfacial defect decreased, and the repetition of appropriate electrical properties was confirmed through Al and HfOx/ITO. The low interfacial defects help electrophoresis of Al+ ions to the PVP GQD layer and the HfOx thin film. A local electric field increase occurred, resulting in the breakage of the conductive filament in the defect.

황성원(HWANG Sung-Won) 한국프랑스문화학회 2011 프랑스문화연구 Vol.23 No.-

Dans cette étude, nous voulons savoir le contenu des programmes nationaux dans l'enseignement de l'histoire-géographie à l'école, également au collège et au lycée. En France, l'éducation civique est ajoutée à l'histoire-géographie dans l'enseignement secondaire. Notre étude recouvre non seulement les programmes, mais aussi les accompagnements qui ont des fonctions de donner des informations pratiques aux enseignants et de les guider pour varier des pratiques pédagogiques. Les enseignants ont l'autonomie pour le choix de leurs méthodes éducatives. Enseigner l’histoire et la géographie, c’est chercher à fournir aux élèves une vision du monde et à exercer une mémoire. aidant à constituer le patrimoine culturel qui permet à chacun de trouver son identité. Les finalités de l’enseignement, qu’elles soient culturelles, civiques et intellectuelles, demeurent identitques et sont communes à l’histoire et à la géographie ainsi qu’à l’éducation civique, juridique et sociale. Nous constatons que le programme scolaire encourage l'intégration des matières, c'est-à-dire entre l'histoire et l'histoire de l'art ou entre la géographie et la biologie etc. Afin, pour que les programmes affichés au Bulletin officiel soient réalisables, ils sont nettement délimités tout en préservant la liberté pédagogique des enseignants.

The purpose of this study is to analyse the eighth grade students` performance of open investigations for two kinds of tasks: the qualitative one which involves the descriptive approach through observation, and the quantitative one which involves the quantitative data processing through control of variables. Researcher`s observation, interview data as well as students` investigation reports, self-evaluations were analysed. The difficulties of qualitative open investigation lie in detecting and dealing with unexpected observations, of which the acceptance and interpretation were influenced by preconceptions. On the other hand, managing several variables, making reliable and valid measures, and quantitative data processing constituted main difficulties of quantitative open investigation. Some students could recognize the deficiencies of their methods and findings in qualitative one, but few in quantitative one. These results suggest the teaching point for each task of open investigations.

This study attempts to suggest marketing strategies of pork brands by analyzing factors, which is important in brand quality management. For this purpose, this study compares the pork brand evaluation standards of the Korea National Council of Consumer Organizations (KNCCO) with excellent pork brands in production and marketing perspective. The results show that farmers and retailers have a different idea for excellent pork brands from KNCCO’s evaluation standards. That is because while farmers and retailers has responded to the changes in consumers’ needs, KNCCO has sticked to more than 10 years old standards. Therefore, the pork brand business should manage its production and marketing in the standards meeting the current market needs in order to improve its brand values instead of following the KNCCO’s evaluation standards.
