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.

Morphological characteristics and taxohomy of the two most important Tarsonemid mutes in agriculture, cyclamen mite (Phytonemus pallidus (Banks), 1899) and Broad mite (Polyphagotarsonemus lalus Banks, 1904) are described and drawings of ventral and dorsal views of females and males of each species are provided. Cyclamen mite was collected from fatsia japonica, and Broad mite was collected from Capcicum annuum, Rhododennon schlippenbachil, impatrens sulianti, Ilex serrata, and Fraxinus rhynchophylla.

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.

Korean construction companies have maintained stable market share based on high technology and cost competitiveness although international construction market has been stalled due to increasing global economy uncertainties. However, Korean construction companies have relied heavily on the general types of projects in Middle East and Asia although the portion of different types of projects such as Build-Transfer-Operate (BTO), Build-Transfer-Lease (BTL), and Public-Private-Partnership (PPP) has been increasing in the market. When delivering huge projects requiring contractors deal with activities from project planning to operation, securing finance sources and profitability is deemed critical. Therefore, Korean construction companies need more attentions on the construction market supported by Multilateral Development Banks. However, Korean construction companies have not utilized effective strategies for the market entry and also government supportive policies are not useful enough to help construction companies. This study aims both to analyze the contract structure of Korean construction companies for presenting critical factors that need to be prepared and to suggest various methods that can be applied to support construction companies that have much interest in the Multilateral Development Banks. According to the results of study, it is important that Korean government provide structural information system, make a specialized organization, prevent over-heating among Korean construction companies, and collaborate with Official Development Agency. In addition, it appeared that the fairness and financial stability of project have recognized main advantages of the Multilateral Development Banks.

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.
