  • This study lies on building the International Standardization of China Arbitration System for improving a relationship of mutual trust and the safety trade between China and other worldwide countries, especially, South Korea as their one of the biggest trading partners through the comparative analysis of China and UNCITRAL Arbitration Law. In this analysis, the differences from China and UNCITRAL in arbitration law are like belows ; lack of arbitrator's international mind, the limitation of private property right, prohibition of Ad. hoc arbitration, arbitrator's biased nationalism, localism, and their short specialties. a deficiency of the objectiveness for arbitrator's election, a judgement rejection of claimants by using nonattendance and walkout, impossibility of prior and temporary property custody for execution of arbitration award. etc. For the improvement of the International Standardization of China Arbitration, this paper propose as follows: 1) Extension of private property right, reorganization of tax system, realization of open competition, exclusion of 'Sinocentrism', globalization of arbitration system 2) The abolition of old fashioned bureaucracy with approval for ad.hoc arbitration 3) An education for arbitrator's internationalization, specialty, and to promote legal knowledge 4) A settlement of the third country arbitrators' selection for reflecting interested party's decision by the court in a selection system of arbitration committee. 5) Institutionalization of arbitration judgment that prevent for claimant's avoidance by using a withdrawal and an intentional absent 6) A permission of the right of claimant's court custody directly before the begging of arbitration request for the prevention for destruction of evidence and property concealment 7) Grant of the arbitration tribunal's interim measures of protection for private property preservation to the third party, proof security, prevention from the loss that selling the corruptible goods 8) Improvement of arbitration's efficiency from the exclusion of the obstacles that are forgery, concealed evidence, and arbitrator's bribe taking Lastly, I hope that this study will serve to promote friendly economic relationship between China and South Korea and strive for international equilibrium through the achievement of China Arbitration's International Standardization. I will finish this paper with a firm belief that this will lead to more advanced studies.

  • 녹색성장은 2005년 이후 논의가 집중적으로 이뤄진 환경과 경제의 조화를 통한 지속기능사회를 건설하기 위한 전략이다. 녹색성장의 개념은 유엔에 의하여 정립되었으며, 아시아 태평양 국가들과 OECD의 새로운 발전 패러다임으로 수용되었다. 이 개념은 2008년 발생한 지구적인 경제 위기의 와중에서 지속가능한 사회를 지향하는 경기 부양 정책을 의미하는 그린뉴딜로 다시 정의되었다. 이에 반하여 한국의 국가 정책 기조로 채택된 녹색성장은 에너지 효율성을 제고하고 관련 기술을 강화하는 경제 성장의 새로운성장 동력으로서의 녹색을 강조하는 한계점을 지니고 있다. 본 고에서는 해외에서 통용되는 녹색성장의 개념과 한국의 녹색성장의 개념을 비교검토하여 기후변화등 환경의 위기에 대응하고 사회적 환경적 지속가능성을 증진하여 지속가능한 사회를 지향하는 발전 정책으로 정의하였다. 지형학은 자연 재해 등에 대한 기후 변화의 영향에 대한 대비 부분에 상당한 기여를 할 수 있을 것으로 생각된다. 특히 재해에 대응하기 위한 지형학도의 작성, 산지 하천의 홍수 관련 연구, 고재해 연구, 해안의 위험성에 대한 연구 등은 시급히 이뤄져야 할 것이다.

  • Present paper describes on/off design performance of a 50KW turbogenerator gas turbine engine for hybrid vehicle application. For optimum design point selection, relevant parameter study is carried out. The turbogenerator gas turbine engine for a hybrid vehicle is expected to be designed for maximum fuel economy, ultra low emissions, and very low cost. Compressor, combustor, turbine, and permanent-magnet generator will be mounted on a single high speed (82,000 rpm) shaft that will be supported on air bearings. As the generator is built into the shaft, gearbox and other moving parts become unnecessary and thus will increase the system's reliability and reduce the manufacturing cost. The engine has a radial compressor and turbine with design point pressure ratio of 4.0. This pressure ratio was set based on calculation of specific fuel consumption and specific power variation with pressure ratio. For the given turbine inlet temperature, a rather conservative value of $1100^\circK$ was selected. Designed mass flow rate was 0.5 kg/sec. Parametric study of the cycle indicates that specific work and efficiency increase at a given pressure ratio and turbine inlet temperature. Off design analysis shows that the gas turbine system reaches self operating condition at N/$N_{DP}$ = 0.53. Bleeding air for turbine stator cooling is omitted considering low TIT and for a simple geometric structure. Various engine performance simulations including, ambient temperature influence, surging at part load condition. Transient analysis were performed to secure the optimum engine operating characteristics. Surge margin throughout the performance analysis were maintained to be over 80% approximately. Validation of present results are yet to be seen as the performance tests are scheduled by the end of 1998 for comparison.

  • 이 논문의 목적은 연안여객선의 항로에 공적개념을 도입시켜 항로전체의 편익을 증대하고, 업체 간 잠재적 경쟁원리를 도입하여 업체효율성을 향상시키는 실행방향에 대한 연구를 목적으로 한다. 2005년 현재 우리나라의 연안여객선은 목포, 마산, 인천 등 10여개의 생활거점 항구도시를 중심으로 106개 항로에 취항하여 이들 도서 주민의 생활교통을 담당하고 있다. 이렇듯 중요한 연안여객선이 다른 교통수단과는 대조적으로 일부 관광항로를 제외하고는 대부분 정체 내지 낙후성을 면치 못한 관계로 주민들이 다양한 서비스욕구를 충족시키지 못하고 있다. 또한 항로가 사유 재산권화 되어 있어 인위적인 항로조정 및 탄력적 선박운행을 기대할 수 없다. 따라서 도시와 도서간에 생활권 형성과 도서지역의 관광산업 등 경제활동의 활성화 제고 및 국토의 균형적 발전을 위하여 연안여객선의 대중교통화를 제안한다.

  • Pollution emission control of the 20th century, for transportation energy, are being enhanced, and then as alternative to this, because hydrogen emit only water gas emissions to be environmentally friendly energy, so hydrogen as a sustainable clean energy is in the limelight. Used in compressed natural gas engines to mix hydrogen and natural gas in both domestic and international technology development and demonstration is being carried out. The hydrogen-compressed natural gas(HCNG) charging infrastructure can be used to build a hydrogen infrastructure in the transitional aspects of a future hydrogen economy society. In this paper, for a demonstration of HCNG charging infrastructure we made and operated a $30Nm^3/h$ hydrogen generating unit and analyzed the result of the operation. We was identified the operating conditions of a reforming reactor and water gas shift reactor from an analysis result, the thermal efficiency was calculated according to the operating conditions of the total hydrogen production process.

  • Organizations pursue a CRM strategy for the purpose of increasing business performance and value. However, firms face a multitude of organizational challenges associated with this endeavor. To reduce their risk of failure, it is suggested that firms undertake a deep analysis of organizational readiness prior to committing to a CRM initiative. Insurance sector is no exception to this fact. There is an increased need to concentrate on the various challenges thrown open by the public insurance firms in implementing CRM. Many insurance firms have invested into customer driven CRM but research indicates varying outcomes (Schmith 2004). While it is clear that there are significant issues involved in the CRM implementation and success and environment faced by the public sector. It is clear that business should have an easier time in applying CRM systems is the strategic value for public sector. With customers demanding more service and accessibility from administrators, public sector CRM software technologies have to offer best solutions for achieving process and cost objectives (Souder 2001). With results which go far beyond improved service delivery and include sustained cost reductions, increased customer knowledge and better employee morale, CRM software implementation and post product environments offer great upside value. Although there are material differences in public sector use of CRM strategy, they share at least one glaring similarity - they have much to gain from proven CRM software technology. As business methods cross over in the public sector, many government bodies are investigating how they can adopt and adapt various CRM models (Bleyer 2003). There is a need to understand the similarities and differences in public sector CRM to foster shared knowledge, business processes and planning functions to integrate disparate technologies and software platforms and then, of course, the organizational culture to support knowledge sharing (Peters 1997). For the public sector, there are clearly identified CRM processes which have resulted in increased profits and improved efficiency. These have focused on sales, marketing and customer service activities, which often operate along fundamentally different lines in various public sector insurance companies. Thus the present research paper makes an attempt to explore how public sector CRM methods can be adopted and subsequently adapted.
