Turbulent flows around tube banks and in the diffuser were studied using a non-orthogonal boundary fitted coordinate system and the modified K-.epsilon. turbulence model. In these cases, many problems emerge which stem from the geometrical complexity of the flow domain and the physical complexity of turbulent flow itself. To treat the complex geometry, governing equations were reformulated in a non-orthogonal coordinate system with Cartesian velocity components and discretised by the finite volume method with a non-staggered variable arrangement. The modified K-.epsilon. model of Hanjalic and Launer was applied to solve above two cases under the condition of strong and mild pressure gradient. The results using the modified K-.epsilon. model results in both test cases.

The introduction of client server systems raises some serious IS control concerns. Although client server systems increase system flexibility and compatibility, and facilitates system downsizing and process restructuring, multiple operating systems, database management systems, and platforms of client-server system increase th potential exposures and risks of the system. It is needed to recommend the effective control framework to mitigate risks. This paper suggests risks and control framework for client server system. The results of two case studies indicate that program and database management are important as program and data should be located and maintained in client and servers. It becomes difficult to manage divided programs and data logic that are distributed across clients and servers that have different platforms. The case studies of two banks show that the extent of distribution of program and data logic affects the importance of program and database management controls.

Many Korean banks and companies have adopted EDI to replace traditioanal paper documents by electronic ones, which can move much faster with greater accuracy, Also, it is expected to reduce overall costs and maintain good relationships with customers. However, in practice, the performance of EDI seems to be less than expected. The purpose of this paper is to identify the impact of environment and adoption factors on the performance of financial EDI. We proposed a model for the relationships based on the existing literature and peformed a survey of Korean commercial banks and companies using KTNET. The results of this study are as follows: First, the business environment represented by the size of companies and the frequency of transactions showed a negative impact on the performance in terms of efficiency, which is quite converse to the common belief. Second, the technical environment, including computing skills of users and operators, showed a positive impact on the performance in terms of effectiveness. Third, the clearer the adoption purpose, the higher is the performace as intended, while the initiative for the adoption process showed no significant impact.

Component-based method for load model not only should include the performances of the load components, but also should take into consideration the core losses of transformers, the line losses and the capacitor banks. Especially, capacitor bank affects the accuracy of reactive load model in load modeling. But it is difficult to identify actual reactive powers of capacitor banks in power system for load modeling. This research improves the component-based modeling method including uncertain capacitor bank. The proposed method is hybrid technique, which adds the measurement-based method to the existing component-based method for reliable information of capacitor band. The results of case studies were presented to verify the validity of the proposed method.

This paper draws implications on the ship finance of the Korean ECAs for shipbuilding industry from the perspective of WTO ASCM through studying the trade disputes on export credits. In consideration of the underwriting practice on the case-by-case basis, the ECAs' law regimes and their ship finance programs as such would be judged not conferring a benefit. The ship finance of international commercial banks could be treated as a market benchmark for the purpose of determining the existence of benefit in the ECA ship finance. The ECAs share securities with international commercial banks for the same exposure to the risks in a syndicate. Therefore, WTO DSB would rule that the ECA ship finance confers no benefit for individual transactions. The items (j) and (k-1) of ASCM Annex I are not allowed to interpret a contrario.

Alloperla tiunovae Teslenko, 2009 and Haploperla maritima Zhiltzova & Levanidova, 1978, hitherto known only from the Russian Far East, are reported from South Korea. The male of A. picta Zwick, 1973, previously known only from the female holotype collected in North Korea, was described based on numerous specimens collected in South Korea. The species previously reported as Triznaka (?) sp. sensu Zwick, 1973 proved to be A. tiunovae. The generic assignment of both A. picta and A. tiunovae point on certain problems of generic diagnosis of Alloperla Banks and Sweltsa Ricker, and call for a comparative generic review of Alloperlini Surdick, which should focus on Asian taxa.

글로벌 경제의 불확실성 확대와 저성장 지속에 따른 해외건설시장의 성장 정체에도 불구하고 국내기업은 높은 기술 및 가격경쟁력을 바탕으로 견조한 시장점유율을 유지하고 있다. 그러나 해외건설시장에서 투자개발형사업의 비중이 확대되고 있음에도 불구하고 국내기업의 수주는 일반 도급형 사업에만 지나치게 편중되어 있는 실정이다. 사업발굴, 금융조달, 시공 및 운영까지 종합적인 역량을 요구하는 투자개발형사업에 있어서 안정적인 재원조달과 수익성 확보는 무엇보다 중요한 요인이다. 이러한 관점에서 개발도상국을 중심으로 재원투자를 확대하고 있는 다자간개발은행에 대한 관심 제고는 어느 때보다 절실한 상황이다. 그러나 다자간개발은행에 대한 국내기업의 전략적인 접근은 이뤄지지 않고 있으며 정부의 지원정책도 효율성도 낮은 수준이다. 본 연구는 이러한 필요성와 시급성을 바탕으로 국내기업의 다자간개발 은행에 대한 인식과 진출 실적을 분석하고 다자간개발은행의 투자시장 진출을 위한 민간 및 정부차원의 역량과 정책적 지원 방안을 제시하였다. 연구결과에 따르면 다자간개발은행 투자사업은 입찰의 공정성과 재원조달 안정성이 장점으로 평가되었으며 국내기업의 진출 확대를 위해서는 시장에 대한 체계적인 정보제공, 전담조직의 구성과 운영, 기업 간 과당경쟁 방지, 공적자금과의 연계성 확보 등이 중요한 요인으로 제시되었다.

Due to the plethora of political, economic, and social challenges experienced on a global scale in the 21st century, students need to be concerned with more than their immediate surroundings (Johnson, 2005). When implemented in an educational setting, topics encompassing social justice may provide students with the confidence and skills to become "reflective, moral, caring, and active citizens in a troubled world" (Banks and Banks, 2009, p.5). The purpose of this article was to provide examples of undergraduate lessons focused on sweatshop conditions within three time periods of United States history that incorporate social justice into the course curriculum. By implementing social justice lessons into the curriculum, students can engage in critical reading, writing, and thinking about injustices faced by society. Girded with knowledge of past oppression within the apparel industry, students may become actively engaged in challenging social injustices in our world.
