Hydrothermal deposits on deep-sea floors are expected to provide potential metal resources for future demands. Korea was recently granted a prospecting licence to undertake exploration for hydrothermal metal deposits in the exclusive economic zone (EEZ) of the Kingdom of Tonga in the Pacific Ocean. The Korean Deep Seabed Mining Group (KDSMG), which consists of four Korean companies involved in marine technologies, oil and gas shipping, and smelter industries, has conducted research to evaluate the region's resource potential in cooperation with the Ministry of Land, Transport and Maritime Affairs (MLTM) of Korea. Here we present and reflect on the exploration results of these companies and their strategic plans. We also evaluate Research and Development (R&D) progress for the commercial development of seafloor hydrothermal deposits. Our own strategies and prospects for the commercial development of this potential resource are also outlined. We do acknowledge that other potentially important information regarding the amount of ore body, the inside structure, and the metal yields have not yet been clarified sufficiently. As such it is necessary to address these problems through experimental R&D and surveys.

The purpose of this paper is to make research on the settlement mechanism of the commercial disputes between the South and the North of Korea. Also, this paper is to make research on the south-north Korea's cooperative tasks to promote the disputes settlement, including the operation and management of the South-North Arbitration Commission as well as the enactment of the South-North Arbitration Rules. To realize the spirit of the South-North Joint Declaration of June 15, 2000, the Authorities concerned of the South and the North of Korea have reached an agreement titled 'Agreement on Settlement Procedure of Commercial Disputes' on December of the same year. As the follow-up measures of the said Agreement, the South-North Authorities have signed an another agreement called 'Agreement on Organization and Administration of the South-North Arbitration Commission' on October, 2003, which is becoming vital importance for settlement of the commercial disputes between south and north Korea including the Gaeseong Industrial Complex. Gaeseong, a city surrounded by the North Korean military and a symbol of inter-Korean tensions, is now turning into a peace zone where thousands of North and South Koreans are working side by side. The Gaeseong Industrial Complex project, driven by the logic and economic necessity of cooperation, has been steadily moving forward since the North designated it as a special economic zone and has enacted related laws and regulations for its development. Under the situation, the matter of primary concern is how to organize and conduct the Arbitration Commission for the prompt and effective settlement of the south-north commercial disputes. First of all, the South-North Authorities should recognize that the availability of prompt, effective and economical means of dispute resolution such as arbitration and mediation to be made by the Arbitration Commission would promote the orderly growth and encouragement of the south-north trade and investment. In this connection, the Korean Commercial Arbitration Board(KCAB) should be designated as the arbitral institution of the south Korean side under the Agreement on Organization and Administration of the South-North Arbitration Commission. The KCAB is the only authorized arbitral organization in South Korea to settle all kinds of commercial disputes at home and abroad.

The purpose of this research is to find out how the inlet angle of secondary air affects the formation of recirculation zone inside a small incinerator. A commercial code, PHOENICS, is used to simulate the flow field of an incinerator. The computational grid system is constructed by Multi-Block technique. Numerical experiments are done with the five different angles of secondary air inlet. The formation of recirculation zone is evaluated by checking velocity fields. The computational results show that recirculation zone is clearly formed from 60 degree of inlet angle and the zone of recirculation is widen as angle of recirculation is increased to $75^{\circ}$.

Against the background of the rapid development of the Shanghai Metro network, this paper attempts to establish an analytical approach to evaluate the impact of multiple transport network accessibilities on commercial space use in metro station areas. Ten well-developed metro station areas in central Shanghai are selected as samples. Commercial space floor area and visitors in these areas are collected. Using ArcGIS and Spatial Design Network Analysis, the Shanghai Metro network and road network are modeled to compute diversified transport accessibilities. Evidence from land use and commercial space floor area within a 0-to-500-meter buffer zone of stations is consistent with location and land-use theory: commercial land use is concentrated closer to stations. Correlation analysis suggests that hourly visitors to the shopping mall are mainly influenced by metro network accessibility, while retail stores and restaurants are affected by both metro and pedestrian accessibility.

PURPOSES : This study deals with the traffic accidents classified by the traffic analysis zone. The purpose is to develop the accident density models by using zonal traffic and socioeconomic data. METHODS : The traffic accident density models are developed through multiple linear regression analysis. In this study, three multiple linear models were developed. The dependent variable was traffic accident density, which is a measure of the relative distribution of traffic accidents. The independent variables were various traffic and socioeconomic variables. CONCLUSIONS : Three traffic accident density models were developed, and all models were statistically significant. Road length, trip production volume, intersections, van ratio, and number of vehicles per person in the transportation-based model were analyzed to be positive to the accident. Residential and commercial area ratio and transportation vulnerability ratio obtained using the socioeconomic-based model were found to affect the accident. The major arterial road ratio, trip production volume, intersection, van ratio, commercial ratio, and number of companies in the integrated model were also found to be related to the accident.

Numerical analysis for the combustion flow in the combustion chamber of incineration system has been carried out in order to acquire the basic design capability of incineration system. Established mathematical model was applied to the performance prediction of the pre-designed combustion chamber of commercial plant. Especially, combustion characteristics and the variation of flow pattern have been deeply discussed in accordance with secondary air injection. Secondary air injection was effective for the turbulent mixing between air and carbon monoxide/volatile matter resulting in considerably reduced CO content at the exit. Secondary air injection was found to be one of the key design parameters because the size of recirculation zone could be changed with the variation of injection characteristics.

In the metal cutting, machining accuracies had affected by tool deflection that had been generated by acting cutting force on the cutting edges. Generally, the CAD/CAM and a solid modeler had used for the simulation of cutting process only. Some NC codes for metal cutting have been generated by these simulation results. But, machining errors that had generated by the tool deflection has not solved using these system. In this study, determination algorithm for integration zone has been studied using the commercial solid modeler. The tool deflection error has calculated by the integration zone between the small chip and the cutting edges.

This study suggests a reliable auction right analysis system that improves the existing auction right analysis in a sense that the system is more applicable to a real economic world. The existing study has used an auction successful bidding price rate and an auction successful contract price for its estimation of the auction right analysis. But in this paper the degree of market vitality which is provided from the commercial zone analysis is used as an input variable so the expected auction price can be estimated and the auction right analysis is conducted in that manner.

In order to achieve full-scale economic cooperation between North Korea and South Korea, the Gaesong Industrial Complex should reopen first. In this case, the Inter-Korean commercial arbitration system should be clearly established to effectively resolve the disputes arising in the special economic zones of the Gaesong Industrial Complex. Even though the Inter-Korean Investment Security Agreement, the Agreement on the Resolution of Commercial Disputes between North Korea and South Korea, the Agreement on the Formation and Operation of the Inter-Korean Commercial Arbitration Committee, and the Agreement on the Formation and Operation of the Inter-Korean Commercial Arbitration Committee in the Gaesong Industrial District are in place, specific arbitration procedure is not concretely agreed upon and realized between the two Koreas. Therefore, the realization of commercial arbitration between them led by the Ministry of Unification or the government should be accomplished. In addition, it is necessary to consider the administrative trial or administrative litigation system in order to deal with administrative disputes that are not subject to commercial arbitration. Lastly, discussions on legal integration between the two Koreas should continue, focusing on the special economic zone of the Gaesong Industrial Complex, in order to prevent integration from being hindered by a different culture for a long time.
