In SIP(Session Initiation Protocol) environment, the presence event notification operation makes presence service user to recognize presence information status changes of the other party. In conventional method, the user should send each SIP SUBSCRIBE message containing the address of the other party to the presence server. Furthermore each presence subscription requires refresh messages, and the amount of notification messages from the other party becomes large. These facts increases network traffic and the load of presence server. In this paper, to solve these problems a new presence list service has been suggested. It uses a presence list consists of URI of the other party and make it possible to subscribe by using one SUBSCRIBE message. So this method decreases the amount of SUBSCRIBE messages and refresh messages, and it also decreases the amount processing event notification messages from the subscribed the other party. And to increase the efficiency, a presence filtering method which enables to include some parts of selected presence information into the notification message body has been also suggested. The implemented system can reduce SIP message related network traffic and message processing time of the presence server. The performance of this proposed system has been evaluated by experiments, and the results showed decreasing of server processing time.

The study attempts to verify the case related to the notice of payment refusal by issuing bank regarding discrepancy in transport document under L/C(Letter of Credit) transaction. Considering the high portion of trade between Korea and China, Korean companies and banks in L/C transaction should be careful about many unpredictable situations. The case of this study is that Chinese seller(beneficiary) initiated a civil suit against Industrial Bank of Korea to Chinese court and Chinese courts in the first and second trials judged that the notice of payment refusal by Industrial bank of Korea doesn't satisfy Article 16, (c) (ii) (iii) in UCP 600. However, Industrial Bank of Korea implements the judgement even though the judgement is highly biased to Chinese seller. Considering the judgement by Chinese courts, the study suggests some countermeasures to Korean companies and banks which opened L/C. First, the issuing bank should describe the contents of discrepancy specifically based on Article 16, (c) in UCP 600. Second, it is necessary to insert a clause regarding governing law in the L/C contract like sales contract. Third, considering the biased judgement by Chinese court and difficulty in execution of foreign judgement in China, it is recommended to using arbitration as a method of dispute resolution such as ICLOCA and DOCDEX Rules which are international system operated by international instruments because it has legal effects to parties in L/C contracts if the issuing bank inserts arbitration clause in L/C.

The performance of optimistic concurrency control schemes which are generally used for Mobile computing is very sensitive to the transaction abort rate. Even if the abort probability can be reduced by back-shifting the timestamp from the time of requesting a commit, some transactions continuously perform unnecessary operations after the transactions accessed write-write conflicting data. In this paper, we propose an optimistic protocol that can abort the transactions during the execution phase by using the write notification approach. The proposed protocol enhances the performance of the optimistic concurrency control by reducing the unnecessary operations. In addition, we present a simulation study that compares our schemes with the timestamp based certification scheme. This study shows that our scheme outperforms the timestamp based certification scheme.

According to the CISG, there are no special regulations for a reasonable period of time among the obligations to notify the contractual suitability of the goods. As a result, many disputes arise in 'notification within a reasonable period' despite being the most important treaty in practice in defining the obligation to notify nonconformities according to the suitability of goods for each case. Regarding the interpretation of Article 39 of the CISG, various judgments and arbitration decisions are being made in each country for a reasonable period to notify that the goods are not suitable for the contract.There are criticisms that these various views are too harsh on the buyer in the buyer's obligation to notify.It is important to create a unified principle because courts or arbitration agencies of the Contracting States of this Convention interpret in various ways the reasonable period of violation of the contract of goods stipulated in the Convention. Since most of the international commodity trading transactions around the world are regulated by the CISG, it is necessary to analyze and interpret cases in which this Convention is applied in court or arbitral tribunal of each country to derive a unified principle.

Today, administrative legislation is becoming more and more important in that it not only sets the legal life relationship of the people in great detail and detail, but is closely related to the occurrence, extinction, and alteration of rights and obligations held by prisoners. In the United States, the types of administrative legislation are divided into substantive and interpretative regulations, so-called substantive regulations, which give prior notice and opportunity to comment on interested parties through formal or informal administrative procedures in accordance with Article 553 of the Federal Administrative Procedures Act. On the other hand, the interpretation regulation, which is "the regulation established by the Administration for the simple interpretation of statutes," does not require prior notice or comment because it does not affect the people's rights obligations. The Azar v. Allina Health Service, 587 U.S. 1804, 2019 ruling by the U.S. Constitutional Court, subject to this research paper, is about a dispute over a new decision to require Medicare to determine the amount of compensation for care providers that provide medical services for the poor, and should the regulations be regarded as substantive under the Administrative Procedures Act and should not be given a hearing or a simple internal process for processing. Given that the current administrative procedure law of our country stipulates the procedures for administrative pre-announcement through Articles 42.1 and 44.1, but that our courts have not judged violations of legislative pre-announcement procedures under the Administrative Procedures Act so far as to judge the illegality of administrative legislation, the dispute of the U.S. Constitutional Court will provide new implications for controlling legal orders beyond simple legal interpretation and has great significance in terms of readjustment of relevant regulations under future administrative procedures.

Republic of Korea designates a waste disposal site within the fishing zone administered jointly with Chin in the Yellow Sea. The issue of waste disposal at sea is subject to the 1996 Protocol to the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter commonly called London Protocol. China, one of the contracting parties declared that if China becomes a party to a dispute concerning the interpretation and application of the Protocol, the Arbitral procedure of the Protocol shall only be applied with written consent of the Government of China according to the Article 16.5 of the Protocol at the time of its accession. The Article allows any State may declare that, when it is a party to dispute about the interpretation or application of precautionary approach or polluter pay principle, its consent will be required before the dispute may be settled by means of the Arbitral procedure of the Protocol. This paper analyzes the legal basis of Chinese declaration and its implication to parties that may be in dispute with China using international precedents of similar nature and a game theory.

We, currently settled on the peninsula, have a long history and our ancestors lived over the vast land further to the central Asia and northern China. Normally, our ancestors traded with many countries, but they fought battles when they were on bad terms and many countries emerged and disappeared. In this history, a variety of cultures have been established and the traditional martial arts is a part of those cultures. Our martial arts has been almost severed because of the development of fire weapons in the late Chosun Dynasty, Japan's colonial rule, and 1950-53 Korean War. Fortunately, we can study the traditional martial arts from history books, the records on the martial art books and relics. Muyeadobotongji, the martial art book published in the late Chosun Dynasty, regrets the negligence of martial arts Giyae(arts) after Japanese Invasion of Korea in 1592 and the Manchu war of 1636 and accommodated the martial art skills from Chosun, China and Japan. It is useful for studying martial arts, because it contains detailed description and drawings, clothes and accessories, and the specification of the weapons. However, the problem is the level of Giyae of the martial arts organization and individuals based on Muyeadobotongji vary and some organizations are arguing about the numbers.

피의자신문시 변호인이 참여할 수 있도록 명문 규정을 둔 2007년 형사소송법 개정은 진일보한 개정이라 할 수 있다. 그러나, 피의자신문시 변호인 참여 제도는 현재까지도 제대로 활성화되지 못하고 있는 실정이다. 이 제도를 활성화하기 위해서는 첫째, 피의자에게 국선변호권이 확대되어야 할 것이다. 둘째, '검사의 사법경찰관리에 대한 수사지휘 및 사법경찰관리의 수사준칙에 관한 규정'의 문제점이 개정되어야 할 것이다. 셋째, 수사기관에 대한 교육이 강화되고 변호인에게 수사 일정 등 통지가 제도화 되어야 할 것이다. 이러한 대책을 통해 피의자신문시 변호인 참여 제도가 활겅화되어야 피의자의 인권이 제대로 보장될 것이다.
