The purpose of this study is to analyze the problem of confusing the names of Chinese granite used in Korean construction work and suggest the improvement plans for them. Interviews of the experts from the stone company, studies on the existing research literature, and analyses of construction work documents of the 23 construction works which used Chinese granite were carried out to analyze the real condition of name confusion of granite stone. In the analytical result of the real condition, name confusion was classified into 4 types and problems derived from it were done into 4 ones. An additional survey was carried out targeting 34 masonry experts to draw the improvement plans based on the analytical results of the real condition of name confusion. The results show that the most fundamental solution is to continue to make efforts to use exact names when main agents related to construction works communicate with each other regarding Chinese granite stone and the process to make out construction contract documents.

Korean agricultural and rural economics has been gotten more difficult through the introduction of economics system under the control of IMF before problems from open market system under WTO get to be settled. Export should be promoted to get the advantage of open market system and to get over today's economic crisis from shortage of foreign currency. Fortunately, Korea adjoins Japan that is largest importing country of agricultural products in a world, therefore Korean Agricultural products has advantage in export to Japan through open market system. Puyo tomato, specialized agricultural products in Chungman province, has been exported 42.2M/T to Japan from 1994 year to 1996 year. But such exported amount was so small that is less than a 1% of total tomato product in Puyo area. Reasons why export volume to Japan was so small were non standard commodities, non performance of export contract, unfavorable price condition, etc.. But it was major reason that missed optimal exporting period. Therefore this study is aimed at finding optimal period exporting Puyo mini tomato to Japan. According to result of analysis based on monthly price and carried quality data of major tomato market between Korea and Japan, it has more comparative advantage that we export tomato during Period of Dec-Feb. rather than March-May which is currently major exporting period.

Nowadays the flow of international trade is that there seems to appear economic block significantly because most countries contract FTAs, so our market condition is changing to a severe competitive situation. Korea which has 70% of foreign dependence of trade must get involved in regionalism, and also actively promote FTA more than any other countries. FTA on February in 2006, the pharmaceutical industry are anxious. The pharmaceutical industry in Korea has recently come to a crisis that it is hard to expect a growth due to structure of profit and a change for the worse of management. If Korea-U.S. FTA are contracted in this kind of situation, domestic pharmaceutical companies will be at stake. We can anticipate that FTA with the country that has a strong competitive power like U.S. affect negatively on pharmaceutical industry, because the industry doesn't have enough self-competitiveness. Considering this kind of surroundings, we need to present the policy to enhance competitiveness for damage limitation on pharmaceutical industry by Korea-U.S. FTA. Under this background, this research has groped for a direction to strengthen the competitiveness to develop pharmaceutical industry in quality. The competitive enhancement plan is presented which is divided into the government policy part, the R&D part, and the management part. Although Korea-U.S. FTA is analyzed to wither the pharmaceutical industry, it would be thought that it is a good chance to upgrade domestic pharmaceutical industry if we make the best use of it, and also to make in roads into foreign market.

The processing paper has devoted to the theory of the flow equations, the basic derivative procedure, the meaning of a valve flow coefficient $C_v$, the valve Reynolds R$R_{ev}$ and its application for liquid control valves, which applicable under the condition of a non-critical flow and the case of piping geometry factor $F_p$=1.0. However there is no information on the effects of fittings, a critical flow and the flow resistance coefficient of a valve equivalent to that of pipe which is conveniently used in the piping design. Since the piping systems of plants or ships generally contain various fittings such as expanders and reducers due to different size between pipes and valves and there may occur a critical flow, that a mass flowrate is maintained to be constant, due to the pressure drop in a piping when a liquid is initially maintainder ar a saturated temperature or at nearby corresponding to upstream pressure, system designer should have a knowledge of the effect to flow due to fittings and the critical flow phenomenon of a liquid. This study is performed to inform system designers with the critical flow phenomenon of a liquid, a valve resistance coefficient, a valve geometry factor and their applications.

Among all industries, the construction industry still remains a traditional one with low productivity due to its labor-intensive and field-dependent production system, its supplier-oriented industrial structure, and the disruption of the information flow between participants. In addition, the construction industry in South Korea has recently been required to transform itself according to social trends such as aging, the reduction of skilled workers, and the shortening of working hours, and the disaster and death rates in the industry, which are more than twice as high as those in other industries, are making it more necessary to solve chronic safety problems. Therefore, the purpose of this study is to grasp the actual condition of safety management on construction sites in South Korea and analyze cases of K-smart technology utilization for preventing safety accidents on construction sites. The study investigated and analyzed the following. First, construction sites in South Korea were analyzed by type of safety accident, by type of construction, and by construction contract amount. Second, the current status of accidents on small-sized construction sites with a high fatal accident rate and cases of safety accidents on construction sites were investigated. The results of the study are expected to contribute to the dissemination and spread of smart safety technology for not only identifying major factors in safety accidents that occur on construction sites but also preventing workers from suffering accidents.

As the government announced Real Estate Policies on August 02, most areas except for Seoul cities face increasing business risks. Moreover, the government control over financial sectors' loan leads to the highly possible contraction of new distribution markets. The market trend could bring about the reduction of new demand in PF (Private Financing) business that large construction companies mainly concentrate on, and even the business already obtained has a high risk of being distributed, which could result in substantially low profitability. The currently unstable financial structure of most construction companies is caused by the hike of the prime cost of foreign plants except for that of a few construction companies. If PF (Private Financing) business also faces a difficult situation in such a financial condition, even large construction companies come to have the high possibility of a deficiency in credit rating. Accordingly, the major business that large construction companies concentrate on needs the sufficient business review. It is desirable to make a bid for business guaranteeing stability rather than business solely in consideration of profitability, when participating in a competition for a new construction contract.

Vessels are traditionally optimized for a single condition, normally the contract speed at the design draft. The actual operating conditions quite often differ significantly. At other speed and draft combinations, adjusting the trim can often be used to reduce the hull resistance. Changing the trim is easily done by shifting ballast water. There are several ways to assess the effect of the trim on the hull resistance and fuel consumption, including in-service measurements, model tests, and CFD. In this paper, CFD is employed for the assessment of the resistance performance according to the trim conditions. The commercial CFD code of the STAR-CCM+ is utilized to evaluate the ship’s resistance performance on a 6,800 TEU container ship. To validate of the effectiveness of STAR-CCM+, the experimental result of the KCS hull form is compared with the result from STAR-CCM+. It is found that the total resistance of the 6,8000 TEU container ship was reduced by 2.6% in the case of a 1-m trim by head at 18knots.

Since matric suction of unsaturated soil was related to soil and ground water contaminations, it is very important to analyze its mechanism that was represented by shear characteristics. In three phases of soil, a little air makes the condition of unsaturated soil on contract or shrinkage surface between water and air. Capillarity and suction in pore of unsaturated soil cause surface tension and surface force so it makes negative pore water pressure and increases effective stress as a result. Therefore, negative pore water pressure in partially saturated soil affects the soil structure and degree of saturation and it is important to evaluate accurately unsaturate flow and behavior. In this study, the shear strength characteristics of the seven sandy soils were investigated using consolidated drained triaxial tests with special emphasis on the effects of the negative pore pressure and the matric suction. These tests involved shearing under either a constant net confining pressure and varying matric suction or under a constant matric suction and varying net normal stress.

In Mash & Murrell, Diplock J said that "there is an implied warranty not merely that they shall be merchantable at the time they are put on the vessel, but that they shall be in such a state that they can endure the normal journey and be in a merchantable condition upon arrival." But in The Mercini Lady, Field J said that "the goods would be of satisfactory quality not only when the goods were delivered on to the vessel but also for a reasonable time thereafter." and "The proposed conditions were not excluded by clause 18. ${\cdots}$ clause 18 was not to be construed as extending to conditions ${\cdots}$". In relation to the problems on validity of the goods conformity clauses in FOB contracts, when considering Lord Wright's comments ("${\cdots}$ hence apt and precise words must be used to exclude it: the words guarantee or warranty are not sufficiently clear.") in Cammell Laird & Co Ltd v Manganese Bronze and Brass, FOB contracts are fundamentally one that seller's duty to deliver the goods is completing at the port of shipment and "principle of party autonomy" in Contract Law, I do not think that the terms implied by section 14 of the SGA and Common Law cannot absolutely excluded by the goods conformity clauses in sale contracts. Therefore, in order to exclude the implied terms, the parties must very clearly spell out this in the relevant clauses.
