The growth of networks increase the importance of electronic commerces. Since the fair exchange protocol is an important part of electronic commerces, a number of researches have been done in relation to the fair exchange protocol. As the contract signing protocol is a part of fair exchange protocol, many protocols have been proposed, but most of them were focused on two-party protocol. Only a few were on the multi-party contract signing protocol. So far the optimistic multi-party contract signing protocol presented by Baum-Waidner has the least number of rounds in asynchronous network[4]. But, the lower bound on the number of rounds required by any optimistic multi-party contract signing protocol has been not known. In this paper, we present a tight lower bound on the number of rounds for optimistic multi-party contract signing protocol.

Logistics service is a prerequisite for efficient market economy and to support the purchase and consumption by promoting smooth transport goods between economic actors. Especially, logistics activities of the company are the source of essential business activities and competitiveness, which is responsible for the production and distribution of products and services to be delivered to consumers. Domestic logistics companies have to resolve challenges such as petty status and low productivity, inefficiencies in the logistics industry system, limit the growth of third party logistics market according to the growth as 2PL central logistics companies, and absence of global leader in logistics enterprises. This study examines the definition and development of third party logistics and analyzes the domestic third-party logistics market conditions. Based on the former analysis, this paper presented separately the activated measures of domestic third-party logistics by corporate side, the supply side, and the government's policy support.

The business process of global third party logistics company is defined as a network of logistics activities which involves the products that are manufactured in the developing countries, such as Vietnam, China and so on, and delivered to North or South American countries via intermediate stopover sites. The third party logistics company usually uses proprietary logistics information system to support the related logistics activities. However, each consignor sometimes may require different business process based on the customer type or characteristics of their products. Therefore, the third party logistics company need to modify their business process to reflect customer's requirements, resulting in the modification of logistic information systems and additional costs. Therefore, a flexible mechanism is required to efficiently support the various types of requirements by the owners of the products. In this paper, first, we figured out various business rules related to third party global logistics activities. Second, we grouped the identified business rules into business processes, objects, relations, dependency, policy, representations, execution, and resources and further into precondition, postcondition, and invariant based on checking point in time. Furthermore, the categorized rules are classified into inter-activity and intra-activity rules based on the execution range. Third, we proposed a rule syntax to describe the defined rules into scripts which are understood by user and information system together. When each activity is executed, the rule manager checks whether there are rules related with the activity execution. Finally, we developed a prototype rule management system to show the feasibility of our proposed methodology and to validate it with an example.

The merits and demerits of the chaebol in Korea has been subjected to considerable debate in recent years. In accounting research, many papers have been concentrating on tunneling that be designated as expropriation of minority shareholders by controlling shareholders. Although majority previous paper suggested related-party transaction has a negative effect to firm value, some research on related-party transaction argued it has a positive effect, also. We assume that they can't consider compositive meaning of related-party transaction and result of prior studies are mixed. In this setting, we investigate the relation between earnings management and related-party transaction which be known as strategy for tunneling by considering controlling shareholder's ownership.

There are several ways to implement charter parties in the operation of the vessel. Under the time charter party, the charterer borrows the vessel from the shipowner and uses the vessel to benefit his business. The time charter party's legal relationship can be divided into internal and external relationships. This article deals with an internal relationship. The legal matters between the shipowner and charterer are regulated by the agreement. The NYPE is the most widely circulated type of time charter party. According to the NYPE, navigational matters fall upon the shipowner while business matter falls upon the time charterer. There are vague parts in interpreting NYPE articles. NYPE Art. 8, called the employment clause, is one of them. The Master employed by the shipowner should follow the order of the charterer. Whether the charterer has the right to order the Master of the vessel to follow the navigating route recommended by him was addressed in the Hill Harmony case by the UK Supreme Court. The court was affirmative. Under the Ocean Victory case, whether the time charterer has an obligation to order the Master to go out to escape heavy weather from the berth at the port was at issue. The Japanese lower court decided negatively. There is a tendency that many countries insert default rule in the maritime law to apply it to the case at issue in a case where there is no agreement. It serves the enhancement of legal stability; China, Japan, and Germany are such countries. The author thinks that Korea should follow the above three countries' revision of their maritime law.

This study analyzed the effect of related party transactions on the corporate value of Korean firms using panel data regression analysis. We tested the efficient transaction hypothesis and conflict of interests hypothesis which concern related party transactions. Five types of related party transactions were considered, including long term supply contracts, assets and business transfers, affiliate loans, equity investment, and credit offerings. If related party transactions were conducted for the purpose of enhancing corporate efficiency, results would have a positive effect on firm value. If related party transactions were conducted for the purpose of private profits of the controlling shareholders, the results would show a negative effect on firm value. Results were as follows. Firstly, it is confirmed that affiliate loans, equity investment, and credit offerings had negative effects on firm value. This implies that these types of related party transactions used by controlling shareholders for the purpose of their private profit, which supports the conflict of interests hypothesis. Secondly, it was found that long term supply contracts and assets and business transfers had no effect on firm value.

A party who relies on a breach of contract must take such measures as are reasonable in the circumstances to mitigate the loss, including loss of profit, resulting from the breach. Appropriate measures are those aimed at lessing the loss as far as reasonably possible. Such measures will typically be a resale of the goods by the seller or a cover purchase by the buyer. The measures the injured party is expected to take in order to mitigate the loss must be reasonable in the circumstances. Article 77 will be applied to the difference between the amount by which the loss should have been mitigated under Article 77. A reduction of damages is the only remedy available to the party in breach in cases covered by Article 77. If the buyer has received the goods and intends to exercise any right under the contract or this Convention to reject them, he must take such steps to preserve them as are reasonable in the circumstances. If goods dispatched to the buyer have been placed at his disposal at their destination and he exercises the right to reject them, he must take possession of them on behalf of the seller. Article 86(1) requires that the buyer manifest his intention at the moment of receipt of the goods. Article 86(2) envisages that the goods have been dispatched to the buyer and that they have been placed at his disposal at their destination. Article 87 allows him to deposit them in the warehouse of a third person. It is not necessary that the warehouse by public, or that it be a general warehouse for storage. A party who is bound to preserve the goods in accordance with articles 86 may sell them by any appropriate means taking possession of the goods or in taking them back or in paying the price or the cost of preservation. If the goods are subject to rapid deterioration or their preservation world involve unreasonable expense, a party who is bound to preserve the goods must take reasonable measures to sell them. A difference exists between paragraph Article 88 (1) which grants the right to sell, and paragraph (2 )which imposes the duty to take reasonable measures to sell the goods. According to Article 88(2), the party who wishes to sell must give notice to the other party of such intention, to the extent possible.

Several criticisms notwithstanding, the major political parties in South Korea seem to have developed relatively coherent 'collective identities' with regard to the unification question between South and North Korea. A comparative analysis in this paper reveals a certain pattern of convergence and divergence in unification policies among major parties. First, diachronically, the two major political parties in the history of South Korea, which I call for simplicity "conservative parties" and "democratic parties" respectively, have converged into allelosubjective attitudes towards North Korea since President Park Chung-hee's proclamation of peaceful unification plan in 1970. The governments of conservative parties since then promoted allelosubjective relations between South and North Korea, which the governments of democratic parties succeeded and developed into a partial integration policy. Though the succeeding governments of conservative parties of Lee Myung-bak and Park Geun-hye seem to have stepped back from the allelosubjective attitudes, seemingly they have not yet withdrawn to the monosubjective stance before 1970. Next, synchronically, an analysis of the platforms of major parties and their campaign promises in the 20th general election in 2016 reveals converging and diverging points in their unification policies. All the major parties show relatively allelosubjective attitudes towards North Korea, with significant differences. "Saenuri Party," the current conservative party, maintains quite bit of monosubjective attitudes towards North Korea and requires unilateral changes of North Korea in the process of unification. "Justice Party," the minor progressive party, is the most allelosubjective in that it presupposes the co-existence and mutual survival of the two Koreas in unification. In between lie "The Minjoo Party of Korea" and "The People's Party", the two parties separated in the democratic party bloc.
