Trade between Korea and Quingdao, Sandongseung has been developed into Private Trade from the Tributary Trade of Silla. Today there are around 6,000 Korean Enterprises in Quingdao, being $22.5\%$ of total Quingdao trades and $60\%$ in the number of investments and monetary scale. Korea is in the first rank among Quingdao's trade parteners. Trade Dispute Settlement System, however, is still in poor condition. It should be improved for the activation of trade. The big solution is the Unification of Arbitration Procedure. For it, First, The staff of The Korean Commercial Arbitration Board should be dispatched to Quingdao Arbitration Commission. Second, there should be common arbitration rules between two institutes.(The Korean Commercial Arbitration Board and Quingdao Arbitration Commission). Third, a single arbitration panel should be made. Fourth, there should be the unification of methods in choosing the place of arbitration and arbitrators. Finally, a common arbitration institute should be installed.

Passive gas dispersions over a 1/1000 scale terrain model at Eiffel type wind tunnel were reproduced by numerical simulation. Large eddy simulation was used to treat the sub-grid scale turbulences. The terrain features were represented by millions of point forces densely distributed over the solid surface using the virtual boundary method. The model simulations agreed very well with the experiments in a consistent fashion for all wind directions. The measured profiles of the wind speeds as well as the tracer gas concentrations were nicely simulated by the CFD model at most locations scattered over the model terrain. With scale factor adjusted and the thermal stratification effects incorporated, the CFD model was expected to provide reliable information on pollutant dispersions over the real complex terrains.

World Trade Organization(WTO) has 164 members since it has established on 1995. It plays a significant role in solving the world trade disputes. The process of the dispute settlement mechanism includes five steps: Negotiation, Establishment of experts group, Deliberation of appellate body, Execution and Supervision of Verdict and the Sanctions for Default. It suggested that the higher rate of developed countries using mechanism to solving the disputes than developing countries solving disputes by mechanism through the analysis of dispute of WTO members. Meanwhile, the more powerful economic entity is, the more trade dispute will be. There are several problems of mechanism by analysis the recently famous cases of trade disputes: Overburden of experts panel, Low utilization rate of the mechanism of developing countries, Lack of economic competition policy and labor standard terms and Unfulfillment of retaliatory measures of developing countries towards developed countries. This paper propose proper solutions and advises to improve mechanism of WTO dispute settlement.

The airflow characteristics in both the upper plenum and the clean space of clean room are investigated by measuring the pressure distribution of the upper plenum and the velocity profile in the clean space, at the various conditions of the supplied airflow rate, the volume of upper plenum and the air supply type. The performance of vertical air supply type and horizontal air supply type is analyzed in terms of the airflow uniformity which is frequently used in indicating the clean room performance, and the relations among the volume of upper plenum, the supplied airflow rate and the airflow uniformity are confirmed. The results of this experimental study can be applied to the designing of the upper plenum of clean room.

It was numerically studied that characteristics of fluid flow and heat transfer in a tube with disk and annular baffle for heat exchanger of condensing boiler. Using a finite volume technique and CFD code, STAR-CD, the governing equations were solved and the temperature and flow fields were investigated. The interval between tube and annular baffle, height and diameter of baffle were selected as important design parameters, and the effects of these parameters on heat transfer and fluid flow were studied. As a result, in the case of with interval, the pressure was decreased but heat transfer was increased. Also heat transfer was slowly increased as the size of disk and annular baffle were increased and the distance between baffles were decreased.

It is analyzed that constructability of post-tensioning system applying HDPE greased strand that is greased and coated by high density polyethylene on a bare strand in reactor containment building. The improvement of corrosion resistance by greasing and HDPE coating on a strand makes transportation, handling and installation of tendon to be easier. Therefore, serial and repetitive process of post-tensioning composed of construction preparation, tendon installation, stressing and anchoring, grease injection could be improved parallel and lumping process of installation and grouting, stressing and anchoring.

If the mechanical development be applied to the Nuclear Power Plant Structures instead of the standard hook development, the problem of overcrowding re-bars in the anchorage zone can be solved and the construction quality of the concrete work will be improved. But there are some problems in applying it to the NPP structures because of the restriction on the re-bar yield strength and diameter. After the performance evaluation test for the mechanical development, we can develop the new design equation of the mechanical development length in order to solve the limitation and apply it to NPP structures.

One of the advantages using High-Strength steel reinforcement in construction is the economic effect due to the decreasing of its quantity. Also, another good effect is the increases of workability by reason of reducing the congestion. This study explain plan of experiment after analysing of ACI 318, 349, 359 to develop 550MPa re-bar design criteria applicable to flexural members of nuclear power plants.

Recently, High-Strength steel reinforcement has been studied throughout the internal and external. One of the advantages using High-Strength steel reinforcement in construction is the economic effect due to the decreasing of its quantity. Also, another good effect is the increases of workability by reason of reducing the congestion. But, realistically it is not used in nuclear power plant construction site because of the restriction of design standard. The purpose of this report secures the reliability and changes the code through the performance evaluation test of the wall using the high-strength steel reinforcement in nuclear power plant.

New artificial fishing reefs are developed using modified sulfur concrete. Modified sulfur concrete, which is made of by-product aggregates and modified sulfur binder, has good properties, including high density, less water absorption, high strength, high salt resistance, and good affinity for living organisms. This paper shows the mechanical properties of modified sulfur concrete and its field tests under the sea. We have found that the pH-neutral materials attach microalgae and seaweed more readily, compared to the pH-high materials.
