Fisheries products in Korea generally go through three markets, namely the wholesale market at production site (Market A), the wholesale market at consumption site (Market B), and the retail market (Market C), from producers to end consumers. As the products move from Market A through Market B to Market C, the marginal gap of prices asked in these markets demonstrates an apparent relationship. The producers, middlemen, consumers, and governmental departments concerned may influence the marketing prices of fisheries products. This study employing the cointegration theory tries to investigate whether causality of the price-setting among these markets exists and, if any, what it is. The authors have focused their attention on fisheries markets in Pusan, analyzing the long-run equilibrium relationship and causality between the prices of hairtail and squid among markets at different levels. Data used in this study cover the period f개m August 1984 to December 1997 fer hairtail, and the period from May 1989 to December 1997 for squid. The main findings of the study may be summarized as follows: First, regardless of the price time-series of hairtail and squid in individual market, the first difference is necessary fur satisfying the stationary conditions since each time-series is a first integration. This means homogeneous integration of time-series, which is a requirement of the long-run equilibrium of prices at different markets, is satisfied. Second, the study of the long-run equilibrium relationship between the prices at Market A and Market B shows that a long-run equilibrium relationship does exist for selling prices of the two species at Market A and Market B. Third, the ECM (error correction model ) used here to describe the long- and short-run dynamics of price change demonstrates that, in the case of squid, the price change in Market A will lead to a corresponding price change in Market B in the long-run period. In the short-run, however, the price at Market H is not only influenced by the price change in Market A but influence the price at Market A as well, that is, the Prices between Market A and Market B have a feedback effect. It should be stressed that the limitation in data collection, which cover only two species of hairtail and squid, is likely to cause a sampling bias. Nonetheless, we may conclude that a dynamic relation in the formation of prices does exist in view of the transaction amount of species at different markets. It is believed that the conclusion drawn from this study would not only contribute to a long-lasted debate on the direction of causality of price-setting among academic circle and fishing community, but would provide a useful standard for the policy makers in charge of the price-setting of fisheries products as well.

This study is to analyse the applicability of governing law in multi-party contractual relationship of letter of credit. And this study is also to suggest the limits of the possibility of applicable law in multi-party contract. The contract of letter of credit constitutes complex relationship, i.e., applicant -beneficiary, applicant-issuing bank, issuing bank-intermediary bank ect. The law applicable to letter of credit should not use a singular governing law in all credit transaction as sales contract. To solve these problems, the author analysed the law applicable to the credit under multi-party contractual relationship as follow : (1) the principle of party autonomy (2) In the absence of express agreement with regard to the law applicable to the contract, lex loci contractus, lex loci solutionis, the law intended by the parties, the law with which contract is most closely connected. Accordingly, when attempting to ascertain the law governing the credit, it should be borne in mind that the credit involves several contractual relationships. I would like to conclude as follows: 1. The contract between the applicant and the Issuing bank is to be governed by the law of the country where the contract is made, and in which the bank carries on business and has issued the credit. 2. When it comes to the beneficiary-Intermediary bank relationship the following rule is given : The liability of an intermediary bank to the seller is governed by the law the country where the intermediary bank is operating if it is acting as principal. If, however, it is acting as agent(advising bank), it will be the law of the country where his principal is situate. 3. The contract between the beneficiary and the Issuing bank is governed by the law of the country where the payment is to be performed. 4. The contract between the Issuing bank and Intermediary bank is governed by 1) the law of the issuing bank is applicable if the intermediary bank only advises the credit, 2) the law of the issuing bank is applicable but if the intermediary bank makes payment, accepts or negotiates drafts against the tender of the documents, i.e., act as the bank dffecting the payment., 3) the law of the confirming bank is applicable if the irrevocable letter of credit is confirmed by the intermediary bank

군집화(clustering)는 주어진 객체들 중에서 유사한 것들을 몇몇의 집단으로 그룹화 하여 각 집단의 성격을 파악하는데, 실제적으로 각 객체가 유사한지 그렇지 않은지를 측정할 수 있는 도구가 필요하다. 기존의 군집화에서 객체간에 유사하다는 의미는 각 군집(cluster)안에 있는 객체들이 같은 속성 값이 많으면 많을수록 객체간에 유사성이 높아 유사도가 높은 객체끼리 군집을 이루게 된다는 것을 의미했다. 그 중에서도 범주형 속성을 갖는 군집화는 같은 속성 값이면 1, 서로 다르면 0으로 표현하여 유사성을 측정하는 방법이다. 제안된 알고리듬은 속성 값을 0과1로만 표현하는 것에 대한 문제점을 제시하고 서로 다른 속성이라도 속성간에 친밀한 관계가 있다는 개념을 도입하여 어느 정도 유사한 지를 보여준다. 같은 객체간에 같은 값을 갖는 속성이 하나로 없더라도 구해진 유사도에 의해 유사한 개체끼리는 하나의 군집이 될 수 있는 알고리듬을 만든 후 그 군집에 속해 있는 고객들의 니즈와 구매 선호도에 따라 적절한 타겟 마케팅(Target Marketing)을 할 수 있다.

The objective of this study is to investigate factors influencing trust on internet shopping mall and to examine whether these factors on trust have differences between Korean and Chinese users. Based on the literature reviews, this study employs six factors in two groups of influencing factors, web-site characteristics and individual characteristics as key determinants of trust in internet shopping mall. Analysis of 470 responses (Korean: 320 users, Chinese: 150 users) of survey questionnaire indicates the following: In terms of the relationship between web-site characteristics factors and the trust, the results showed clear differences between Korean and Chinese samples. For the Korean samples, transaction security and interactivity were the only significant influencing factors. For the Chinese samples, perceived reputation and perceived size were the only significant factors. In terms of individual characteristics factors, the influencing factors were found identical for the samples. Both propensity to trust and familiarity were significant factors in both Korean and Chinese samples. Based on the findings, managerial implications are discussed in building user trust in internet shopping mall in Korean and Chinese market.

The electronic commerce of agricultural products provides benefits both to the farmers and the consumers because of direct transaction between producers and consumers. This study analyses the factors affecting consumer's purchase intention that are using electronic commerce. And the purpose of this study is to contribute to increasing the farmer's income while operating electronic commerce by applying the results of this analysis. Consumer's purchasing factors in electronic commerce were obtained through literature reviews. The research model is established with the factors and analyses through the structural equation model. The results are as following; the first is how the quality of agricultural products affects positively consumer's satisfaction and trust. When sufficient information about the seller and the products are provided in the shopping mall site there are positive effects on the consumer's satisfaction and trust. The factors of convenience like purchasing time, saving, delivery convenience affect positively consumer's satisfaction. However, the relationship with trust enhancement could not be confirmed. In addition, hypotheses of positive relationships between economic feasibility factors like low price, satisfaction and trust, were rejected. Finally, consumer's satisfaction affects trust, and both the consumer's satisfaction and trust affects positively the purchase intention. In summary, in the electronic commerce of agricultural products, consumers might use electronic commerce as they purchase the reliable high quality products directly from farmers rather than be affected by economic feasibility and convenience factors.

A purpose of this study is to measure degree of solidarity and conflict of the beauty salon franchisees according to an influence strategy of franchiser and grasp characteristics revealed from managing a franchise system. This will also contribute to improving results of franchise systems and considering a direction for development. This study examined existing studies relevant with conflict and solidarity and analysed relativity between relevant variables and grasped the flow of studies and then set hypotheses in order to present a device for decreasing conflict within a franchise system of beauty shops and for increasing a solidarity and subsequently analysed samples and tested data. The data for this study are researched by sending questionnaires to beauty salons which participated in one of franchise systems and they are analyzed by various methods in a statistics. After studying some relevant theories, this study used the definition of the franchise system in beauty salons as an entity of a political-economy paradigm. A franchiser desires to influence member shops with an influence-strategy. Therefore member shops which perceived it go through a conflict and then such a process is revealed as making significant influence on solidarity. Beauty salon franchise exists by reciprocal confidence and transaction. If an opportunism gain in influence owing to an conflict intensification, there would be no steady formation of relationship. Therefore the head office should develop a member-shop-management-system by more scientific and more technical methods and prevent, in advance, member stores from seeking for negative opportunism.

This paper presents the iron core design method of a high temperature superconducting (HTS) transformer considering voltages per turn (V/T). In this research, solenoid type HTS coils were selected for low voltage (LV) winding and double pancake coils for high voltage (HV) winding, just as in conventional large power transformers. V/T is one of the most fundamental elements used in designing transformers, as it decides the core cross sectional area and the number of primary and secondary winding turns. By controlling the V/T, the core dimension and core loss can be changed diversely. The leakage flux is another serious consideration in core design. The magnetic field perpendicular to the HTS wire causes its critical current to fall rapidly as the magnitude of the field increases slowly. Therefore in the design of iron core as well as superconducting windings, contemplation of leakage flux should be preceded. In this paper, the relationship between the V/T and core loss was observed and also, through computational calculations, the leakage magnetic fields perpendicular to the windings were found and their critical current decrement effects were considered in relation to the core design. The ％ impedance was calculated by way of the numerical method. Finally, various models were suggested.

B2C EC has two kinds of perspectives such as technology-oriented and trust-oriented perspectives. As lots of fraud damages on the B2C EC have been reported every day, the trust-oriented perspective receives lots of attention. In this study, an integrative typology for developing and validating trust measures for B2C EC proposed by McKnight et al.(2002a) and McKnight and Chevany(2002b) has been used for trust-oriented perspective, and the TAM(technology acceptance model) model proposed by Fred Davis in 1985 has been used for technology-oriented perspective. An research model had been developed by using the 4 factors of an integrative typology and 5 factors of the TAM model such as perceived usefulness, perceived ease of use, trust beliefs, intention, and actual transaction. All 13 hypotheses had been proposed from this research model and tested by field study. 12 hypotheses, including the 4 f actors of an integrative typology as antecedents on trust beliefs, were significant, whereas the hypothesis 5 on the relationship between structural assurance and perceived ease of use was insignificant. Structures on B2C EC like guarantees, regulations, promises, legal recourse, or other procedures seemed to be difficult to B2C EC customers. Therefore, these structures should be developed more easier to B2C EC customers.

This study compares the SGA and CISG to find out the difference of the criteria for calculating damages. and it intends to give some important points in trade practice. The damages is intended to compensate the victim for the breach of contract but there are differences between SGA and CISG as follow. First, the SGA and CISG have the same purpose of claiming damages. Both laws and regulations are subject to a full indemnification to compensate for the breach of the contract by the amount equivalent to the loss suffered by the victim. Second, in the general principle related to the calculation of damages, both law enforcement officials are required to be able to predict damages caused by breach of contract. In the case of SGA, however, a foreseeability test or remoteness of damages is required for the relationship between the contract violation and the loss. In other words, it can be said that the causal relation between the contract violation and the damage is strictly applied rather than the CISG. Finally, both laws and regulations of SGA and CISG have a big difference in criteria for calculating damages. In the CISG, after the contract is canceled, it is classified according to the existence of the alternative transaction and the damage amount is calculated based on the contract price. On the other hand, the SGA estimates the loss based on the market price at the delivery of the goods, reflecting the change in the market price instead of the contract price of the goods.
