The Arbitration Act of Korea was promulgated in 1966. Since the promulgation of Arbitration Act of Korea, consecutive amendments took place in 1973, 1993, 1997, 1999, 2001 and 2002. Among the various set of amendments, those of 1999 were designed to accommodate the UNCITRAL Model Law on international Commercial Arbitration of 1985. Korea has acceded to special international conventions on dispute settlement such as the New York Convention of 1958 and the Washington Convention of 1965. The Korean Commercial Arbitration Board(KCAB) administers the arbitration proceedings in accordance with its Arbitration Rules approved by the Korean Supreme Court. Since the establishment of the first Arbitration Rules in 1966. consecutive amendments took place in 1973, 1981, 1989, 1993, 1996, 2000 and 2004. The KCAB plans to enact the International Arbitration Rules, which will be available to disputing parties in addition to the KCAB Arbitration Rules. In 2005, arbitration applications received at KCAB recorded a historic high at 213 cases, an increase of 22% from 175 cases in 2000. But in 2005, the total amount involved in the arbitration cases decreases to US$ 129 million, a decline of 63% from US$ 346 million in 2000. The KCAB should take the following measures for activating the commercial arbitration system: the globalization of KCAB, the advertisement of arbitration system, the security of qualified arbitrators, and the enhancement of the secretariat service. In conclusion, the KCAB should make efforts for the development of the arbitration system and for the upgrade of customer satisfaction. Moreover the KCAB should make further efforts to grow into a global arbitration institution as well as strengthening relations with international arbitration institutions.

Objectives This study was conducted to suggest a standard operating procedure (SOP) in order to improve the reliability of tongue-image analysis system. Methods An affecting-factors list was made, which may affect the diagnostic parameters of the tongue-image analysis system. They were sub-classified into two groups: controllable and uncontrollable. Only the controllable factors, which could affect the results and easily set-up, were included into the SOP draft. Affecting factors control experiment was performed to investigate the effects of controllable factors, whose influence on diagnostic parameters of the tongue-image analysis system is ambiguous: rehearsal for tongue extrusion; alignment of camera axis; and presentation of a guideline. Three subjects volunteered for this experiment. Each of three variables was implemented twice in a random order by two operators on the subjects. Finally, 96 tongue images obtained in the aggregate. The diagnostic parameter set as a primary outcome in this experiment was the percentage of tongue coating. Results All of the control variables were not significant in both operators; however, the presentation of a guideline was relatively more affect than two other variables. Interaction effects among the variables were also insignificant. Therefore, the presentation of a guideline was included in the final SOP and the other variables were not included. Conclusions We suggested the SOP which could be used for both experimenter and subject. Moreover, Each of the SOPs applied to various types of tongue-image analysis system should be developed in order to improve the reliability.

Pump-turbine system is widely used by the hydropower industry for stabilizing the electrical grid in the vast growing economy of most developed countries. This study only investigates the Fluid-structure Interaction (FSI) analysis of the pump-turbine system at various operating conditions. The FSI analysis can show how reliable each component of the system is by providing the engineer with a better understanding of high stress and deformation points, which could reduce the lifespan of the pump-turbine. Pump-turbine components are categorized in two parts, pressurized static parts and movable stressed parts. The fixed parts include the spiral casing, top and bottom cover, stay vane and draft tube. The movable parts include guide vanes and impeller blades. Fine hexahedral numerical grids were used for CFD calculation and fine tetrahedral grids were used for structural analysis with imported load solution mapping greater than 90 %. The maximum equivalent stress are much smaller than the material yield stress, and the maximum equivalent stress showed an increasing tendency with the varying of operating conditions from partial to excessive at both modes. In addition, the total deformation of all the operating conditions showed a small magnitude, which have quite small influence on the structural stability. It can be conjectured that this system can be safely implemented.

선형발전기와 연성된 원통형 부이의 수직운동으로부터 파랑에너지를 추출하는 파력발전장치의 설계과정을 소개하였다. 최대 파워는 최적조건($c_{PTO}=b_T$, ${\omega}={\omega}_N$)에서 발생하며, 공진조건시 부이의 수직운동 고유주파수와 속도스펙트럼의 피크 주파수를 일치시키지 않고 의도적으로 고유주파수를 15% 크게 설정하면 추출파워의 최대값을 더욱 높일 수 있다. 이러한 방법을 통하여 추출 파워의 증가와 함께 부이의 흘수를 낮추고 동시에 PTO 감쇠력을 줄일 수 있기 때문에 발전장치 제작 비용을 낮출 수 있는 부수적인 효과를 얻을 수 있었다.

With rapid expansion of the water market and growth of water companies, the recent trends in international water industry show that standardization of service activities concerning management of water and wastewater system (ISO/TC 224, to be issued in the second half year of 2007) is expected to have a large influence on the global water market including liberalization of water service market. In the Draft International Standard(DIS) of ISO/TC224, Performance Indicators(PIs) are suggested to estimate the service activities relating to water and wastewater treatment facilities. PIs have been developed in many countries including some international organization(World Bank, IWA and etc.) for service benchmarking. To evaluate public service level and establish plans to improve service level of wastewater utilities, we developed PIs for 120 items and applied them to 10 sewage utilities in the consideration of their scales, circumstances and conditions. In this study, we verified the applicability of the developed performance indicators(PIs). So, we concluded that PIs developed for the purpose of this study can be a useful tool applicable to objective evaluation of the service level of sewage utilities. Using the evaluation tool of PIs developed, it can also be used as a benchmarking tool in this industry as well as for enhancing the efficiency of operation and management of the sewage system. It will also contribute to the water resource management through determination of investment priorities based on the evaluation results and to raising international competitiveness of the domestic sewage utilities to meet the future opening of the water market.

Body shape of a child in elementary school is distinguished by physical differences in the form of low weight, normal weight and obesity, which are influenced by various periodic environments. In particular, there are hardly any patterns for obese children in elementary school to choose. To this end, the purpose of this study is to supplement the problems with the production lines of the companies for children's patterns as well as an analysis on the physical characteristics of obese children and to suggest the patterns appropriate to obese children. This study employed obese children from the 3rd- to 5th-grade elementary school students whose number has been rapidly increasing and conducted a questionnaire regarding the draft of the patterns for obese children on their mothers and the makers of children's clothing. Based on the results, the study compared and analyzed ordinary children's patterns to the patterns in question by suggesting a dimension system for Korean obese children. The results are as follows. The obesity rate of the children in elementary school has been grown in significant numbers every year, whereas obese children's sense of self-identity and degree of satisfaction with their patterns appeared to be much lower than other ordinary children in the peer group; also, the satisfaction level their mothers with their children's patterns appeared to be low. In order to verify the degree of the children's satisfaction with their patterns, the study suggested a dimension system for the obese children and displayed appropriateness by comparing the children patterns from ordinary companies and the patterns in question.

To establish a vessel safety management system for improving the safety of vessel's traffic and preventing vessel's traffic accidents, the state of marine traffic in the Busan South Port was investigated and analyzed as preliminary survey of the countermeasures. As a result of the study, there are 1,158 vessels in a day, 48 vessels in an hour, and the maximum traffic is about 118 vessels between 16:00 and 17:00 hours everyday, which requires to establish and operate a traffic control system necessarily for ensuring vessel's traffic safety. Furthermore, passages of tanker, passenger ship, cargo vessel and government vessel showed to sail along main traffic lane to be obtained enough sea depth at the survey area. However, passages of fishing vessel and launch showed to sail freely at all survey area owing to outstanding maneuverability and a shallow draft. Some vessels of launch sailed along main traffic lane, but other vessels crossed to sail it. The passages to cross main traffic lane is higher the risk of collision. Therefore, safety measures are urgently needed for the operation of the Busan South Port management system and the prevention of marine pollution.

In this study, we studied the ride quality considering the deterioration effects of the three type couplers (single, double, and ring types) for EMUs. In order to know the impact occurred when an urban transit vehicle is under breaking, we tested the conditions of the service brake and the emergency brake. Normal coupler models without any slack showed similar dynamic performance results under all breaking conditions. But if the couplers become old, the initial pre-stresses are removed because of permanent compressive deformation in rubber. For three types of the old coupler models without the initial pre-stress, we evaluated dynamic performances of each type. As the results, the maximum and average acceleration levels of the double type and the ring type were similarly low in all conditions. But the accelerations of the single type coupler was high when compared to those of the double and ring types. In addition, Jerk value of the single type model associated with ride quality was high up to 15 times to the ring type in condition of the service braking in empty vehicle weight. Jerk value of the double type model was high up to 6 times to the ring type.
