This paper is made to suggest a future strategy for the Korean High Resolution Wide Swath Synthetic Aperture Radar (HRWS SAR) satellite development by surveying the current trends for the SAR satellite technologies. From the survey, the latest SAR technology trends are revealed of using Digital Beam-Forming (DBF), SCan-On-Receive (SCORE), Displaced Phase Center Antenna (DPCA), interferometry, and polarimetry for exploiting the SAR imagery. Based on the latest SAR technology trends and the foreign HRWS SAR development cases, the strategy for the future HRWS Korean SAR satellite development is suggested to develop the DPCA and SCORE technologies by using the KOrea Multi-Purpose SATellite-6 (KOMPSAT-6) which is going to launch in a few years, and consequently to develop the HRWS SAR satellites which can monitor the whole Earth at weekly intervals.

The purpose of this study is to conduct classroom-friendly learning activity for sustainable development and to find out the learner's understanding level of experiences on sustainable development. The results of this study could be summarized as follows. First, classroom-friendly learning activity for sustainable development which is focused on the sustainable flea market is concerned about enhancing learner's understanding sustainable development. It could be emphasized a viewpoint of sustainable development, and a possibility of expanding learner's experience in dealing with sustainable development. Second, this study shows also a application of the teaching & learning strategy for classroom-friendly learning for sustainable development. Three different group of pre-service teachers were participated in sustainable flea marker activity. It is considered to make the student be able to catch up core knowledge and value of sustainable development during the classroom-friendly learning activity. In conclusion, this research asserts that classroom-friendly learning activity for sustainable development could make students improve the knowledge and value of sustainable development. It is emphasized to advance education for sustainable development as a new teaching & learning strategy.

This paper addresses the operation, problems, and development policy of Gwangyang Port, Korea. This paper aims to analyze the operation condition and problems of Gwangyang Port and suggest long-term policies for developing Gwangyang Port as a logistic hub in northeast period. It is made up of three main sections: the operation, problems, and forecast of freight volumes; analysis of operational results of Gwangyang Port; development strategies of Gwangyang Port as a Logistics Hub. This paper was mainly based on a review of current papers/reports, an analysis of secondary data, and questionnaire survey. The major development strategies identified consisted of expansion regular service sea-route, formation of inter-modal transportation system, strengthening of port sales for Gwangyang port's recognition, securing operation-profits by fixed cargo volume, and promotion of free tread zone.

In this paper, AC electric vehicle propulsion system(Converter/Inverter) using high power semiconductor, UM(Intelligent Power module) is proposed. 2-Parallel operation of two PWM converter is adopted for increasing capacity of system and the VVVF inverter control is used a mixed control algorithm, where the vector control strategy at low speed region and slip-frequency control strategy at high speed region. The proposed propulsion system is verified by experimental results with a 1,350kW converter and 1,100kVA inverter with four 210kW traction motors.

The purpose of this paper is to increase the competitiveness of firms by establishment of green marketing strategy and its application to a new alternative energy development, ultimately contributing to the advancement of national economy. This study adopted an integrated approach to develop a strategic theory of 'Sun Tzu on the Art of War' that is one of the oldest military treaties and still applicable to today's management development. It applies to the empirical result from a new alternative energy development. For more qualitative improvement of this paper, it needs further detailed studies in both theory and practice in green marketing theory that is applicable to the new alternative energy development.

This article examines the way of the functionality of policy instruments for the development of renewable energy through the case of the wind power. The general barrier of the renewable energy development is considered to be the economic barrier. However the principal issue is the political barrier without the broad cooperation between the host government and the firm. Maintaining the long-term competitive advantage requires the shift of not only the strategy following the external circumstance but also the internal capacity development to utilize resources. Thus the comparative case study of Sri Lanka and Germany proposes the analysis of the supply-push and demand-pull policy with five patterns on the development of wind power in order to suggest how the functionality of policy instruments must be served to foster the wind power.

The competitive strategy perspective is one of the important approaches to develop ecotourism sites. It increases the residents' profits and overcomes the instability of the supply in the marketability. The study aims to explore the ecotourism successful factors based on competitiveness strategies. We found seven key success factors of the competitive strategy approach in the ecotourism industry as the guarantee of sustainable ecotourism as follows: infrastructure, operation management, product/technical development, human resources, service system and cultivation of tourists' understanding and behavior, marketing activities, and local resources. Conclusions and practical implications for successful factors of ecotourism are presented according to the result of the in-depth interview and focus group interview with ecotourism experts.

Purpose: This study aims to overcome the problem of private education market environment which is polarized into commercialized large private education institutions and small and medium sized private education institutions in a poor business environment, and develop systematic performance measurement model applicable for small and medium sized private education institutions. Methods: To develop the BSC which measures financial and non-financial indicator in a balanced manner and introduce the BSC into private education institutions that contain conflicting goals "EDUCATION" and "PROFIT". In particular, Utilizing the methodology of AHP, the priority of strategies and execution assignments are derived. Results: BSC model was developed and introduced by cooperating with executives of the private education institution. Moreover, the study permits to achieve the strategy, enterprise-wide vision and mission by deriving strategy map and applying it to the private education institution. To measure the performance of BSC model instruction, KPI corresponding to the strategic objectives of each perspective was derived. Conclusion: BSC model generally introduces to large-sized companies and public institutions. In this study, BSC model is developed by focusing on small and medium sized private institution. Furthermore, this study is more than simple model development, it makes a connection with achievement of strategic objectives, enterprise-wide vision and mission through strategy map and strategy execution method. Through the developed BSC model and strategy execution method, utilization plan in practice and customized model for private education institutions coexisting profit and non-profit objectives were developed, and academic implications were presented.
