The purpose of this study was the evaluation of spectral transmission of the commercial three shade guides and the relationship of hue, value, and chroma according to the transmission rate. The spectral transmittance of three shade guides - Vita Lumin Shade Guide, Vintage and Unibond Shade Guide, and Vitapan 3D-Master Shade Guide - were measured. For direct transmission measurements, each shade tabs were placed at the entrance port of the 1mm diameter intergrating sphere. The intensity of the light source passing through the shade tabs to the right angle was continuously recorded for wavelength from 400 to 700 nm. A transmission spectrum and digital data were obtained for each measurement and they were evaluated using Microcal Origin program. The obtained results of this study were as follows : 1. In Vita Lumin Shade Guide, sum of the transmission rate of the shade tabs at the wavelength 400-700nm was decreased in agreement with the arrangement order at each A, B, C, D group, except D4 shade tab. However, there were no relationships between the transmission rate of the shade tabs and the value-oriented. 2. In Vintage and Unibond Shade Guide, sum of the total transmission rate of the shade tabs was decreased in agreement with the arrangement order at each A, B, C, B group. When all shade tabs arranged in value-oriented, transmission rate was accord with the order, except D4 shade tab. 3. When shade tabs of the Vitapan 3D-Master Shade Guide have the same value and hue, sum of their total transmission rate decreased in accordance with the chroma-oriented. When the shade tabs have the same value and chroma, there were no differences from the order of the transmission rate to the various hue type. However, in the 'R' tabs of reddish hue type, the transmission rate increased at the long wavelength range area. In conclusion, we need the quantitative analyzing instruments in transmission determination. Vitapan 3D-Master Shade Guide covers the tooth color space taking into account the parameters of the systematic value, chroma, hue oriented, and the transmission rate relatively accorded with that sequence.

Jinhae port was determined to be the position of Busan second new port construction in January 2019. Extra 21 berths will be built in there by 2040 and then huge Busan new port will be made with 57 berths. It’s a good opportunity for GyeongNam port logistics industries to develop. In this regard, this paper try to suggest several proposal to achieve sustainable growth of the port logistics industries in GyeongNam province. First, It’s very important to establish a independent body with highly professionality suitable to operate large scale cutting edge port. And these has to have comprehensive autonomy in decision-making process. Second, Both regulatory body and operating body should accumulate extensive experience regrading the port operation through the diverse channel. Third, Because highly skilled human resources plays essential role in operating port system, GyeongNam should set up specialized manpower training plan and execute this. Fourth, Because port cluster can provide high quality customer service, GyeongNam should advance the policies to establish port cluster actively.

This study attempts to mainly investigate the possibility of resolutions of the Korea-America commercial frictions through the WTO's Dispute Settlement Body(DSB). In order to archive this goal, I checked WTO's dispute settlement system and clarify the differences between GATT and WTO. At the same time, I examined the position and present condition of WTO's DSB. And I tried to investigate case studies. Through these analysis, the results of this study are as follows: The former GATT had a few defects as a commercial dispute settlement organization. But WTO has developed more transparent, predictable and stable dispute settlement system than the GATT. The characteristics of WTO's DSB are summarized as below: First, uniform dispute settlement system. Second, principle of DSU(Understanding on Rules and Procedures Governing the Settlement of Dispute) preemption. Third, the prohibition of unilateral judgement and enforcement. Fourth, reverse consensus system. Finally, time-limited dispute settlement procedures. Therefore, because of these characters of WTO's DSB, many courntries frequently used WTO's dispute settlement system than earlier GATT. So the possibilities that can be resolved the commercial pending problems between Korea-America by the WTO's DSB are increased steadily. In this connection, we have always maintained defensive position in commercial negotiations between two countries. As stated in earlier food case study, the existence of WTO's dispute settlement system enhanced to a certain degree our bargaining power. Moreover, America is the first country that was lost a case at the WTO's DSB. From these points of view, we can know that WTO is taking its place as a stage of commercial dispute settlement between the two countries. It has always worked upon the power in commercial negotiation between countries. And America has such a power. It is proved clearly through the case of America-Japan auto negotiation in 1995 and America-China intellectual property rights negotiation in 1996. But we don't have such a power relatively. So we were in a defensive position when America called for market opening or we negotiated with America on commercial pending problems. But WTO has an effect to restrict the unilateral and unfair use of power by the powerful nations like America. And an example proving that facts is already found in many cases. Although WTO mechanism has a limit itself, we must have an idea to use a WTO's dispute settlement system actively. Accordingly we need to improve a commercial organization into single and uniform one. In conclusion, I think that the advent of WTO's DSB gives a measure to cope with the unfair commercial pressure of the powerful nations, America, to us having a weak bargaining power relatively. So we will have to analyze completely that what it is, how it work, and how we use. At the same time, we will also have to improve our laws and systems concerning international trade and unify our commercial organization.

Multimodal transport is the new mode of trnasport that is introduced since 1960's. This can be defined that international multimodal transport means the carriage of goods by at least two differnet modes of transport on the basis of a multimodal transport contract from a place in one country at which the goods are taken in charge by the multimodal transport contract from a place in one country at which the goods are taken in charge by the multimodal transport operator to a place designated for deliery situated in a different country. But this is a different method from the traditional marine transport. So this method have caused many complicated problems in relation to the liability of the mutimodal transport operator. Namely, in many cases, the damage of container cargo could not be discovered well during the time of transport and discovered at the destination, Therefore, we do not know the precise place where the damage took place. In this case, we could not know thw carrier who have to be burdened with the responsibility of reparation and don't know the principle of liability that have to be applied. In connection with this point, many countries have endeavoured for amny years, and as a result of this effort, U.N Convention on International Multimodal Transport of Goods was materialized in 1980 by UNCITRAL. According to this convention, the subject of liability was based on the uniform liability system. But in the limited cases, this convention adopted the network liability system and hence we can say that it accepted the modified uniform liability system substantially. However, in contrast with this condition mentioned, we do not have any legal arrangement to regulate the multimodal transport yet in our business law. Moreover, in this circumstances, we have to depend on the analogical construction from the marine and/or land transport provisions in the business law, but the provisions regarding those transport are out of date. Accordingly we could not cope with the generalized situation of multimodal transport very well. Therefore, we have to introduce some new procisions to regulate multimodal trnasport in our business law. And when we considered the legislation of the new provisions, it is desiable to harmonize with the international rules including the U.N. convention. In order to do so, we have to excute the research dleliberately about these international rules and finally in relation to our maritime policy, we have to consider the position of shipowner as well as those of consignor.
