This Research is focused on ancient battle formation basing on the layout drawing of Yijinchongbang (manuals of learning military formations) in a strategy book in the late Joseon dynasty. The research topic is the principles of organic composition of battle formation and battlefield operating system by reforming the basic model of ancient battle formation. The research method is comparative analysis by reforming the battlefield operating system of types of disposition such as Obangjindisposition(Bangnjin; battle formation, Jikjin; direct battle formation, Gokjin; bend battle formation, Wonjin; round battle formation, and Yejin; keen battle formation), and Hyunmoojindo; turtle battle formation, Paljindo; all-rounder battle formation, Yookhwajindo; six flowers battle formation, Gugunjindo; nine forms battle formation. From the study results, Standoff Bombing of the battle formation in the late Joseon Dynasty basically started out from magic battle formation, but was then transformed into square, rectangle, pentagon, and circle. Also, the battle array composition used a 5-linear structure and was composed of 5 systems of circulation such as rectangle, square, diagonal, curve, and circle. The research findings elucidate the battlefield of the Joseon dynasty by establishing the real battle formation, and thus have military and academic value in suggesting possible tactics that can be used by modern training of military.

The Russo-Japanese War(1904-1905) in the early 20th century greatly influenced the international politics in Northeast Asia and the destiny of both countries. There are many studies on the cause of the outbreak and its effect on the Korean peninsula. The victory and defeat of the battle of Tsushima also the subject of research by renowned scholars and navy officers. Many previous studies have analyzed the process of engagement. However, There was a lack of research that analyzed at the tactical level of naval commanders. Therefore, this study tries to review the battle of Tsushima in terms of tactical level, that is formation, maneuvering, damage control. Naval operations at sea with many variables are not always done as planned. The intuitive judgement and readiness have had a decisive impact on victory and defeat. The analysis of the naval warfare on the basis of formation, maneuvering, and damage control makes the cause of the win more clearly. The conclusion of the this study can be summarized in five ways. First, victory would be achieved through the suppression of the beginning. The destiny of the Tsushima battle was determined by an 1 hour after first firing. The Japanese fleet caught fire by paralyzing the command and control capabilities of the Russian fleet. Second, the Japanese fleet's power was superior to the Russian fleet. In general, Japan and Russia had similar powers, and Admiral Togo's "T crossing tactics" decisively contributed the victory. However, when compared to the weapon system level, formation and maneuvering, Japan was much more dominant. Third, people realized that one side to be annihilated in the battle between similar powers after the Tsushima battle. The common perception before the Battle of Tsushima was that the battle ship would not sunken, and that the result of wiping out was difficult. However, there is s time for one sided victory and defeat depending on the early suppression nad the destruction of the command and control ability. Fourth, it is the importance of damage control ability. The main cause of the Russian fleet's loss of command and control ability was thick smoke from fire, and maneuverability was greatly deteriorated due to coal overload. In this way, importance is still valid after more than 100 tears. Fifth, the area of uncertainty. In the navy battles, one or two shots of clear firing in the beginning and small misconception and minor mistakes decide win or loss. Ultimately, this area of fortune can be linked to mindset of the commander. I hope this research will be help to naval researchers and naval commanders at the sea.

In order to restore the Hwangsanbeol Combat at present, it is necessary to make a close examination on the name of the military cops, the number of units, and the numerical strength, an unit organization, and a combat formation. Based on Samguksagi, Samgukyusa, other historical documents and military history information, I tried to restore the Hwansanbeol Combat as follow. The Shilla, at the 7 year of Mooyeol Dynasty, AD. 660, maintained 35 military units. The Shilla committed18 military units from among 35 units to battle against Baekje at the 7 Year of Mooyeol Danasty. The names ofmilitary units are as follow: 1) Daedang, 2) Sangjoojeong, 3) Hajoojeong, 4) Seodang, 5) Nangdang, 6) Eumlihwajeong, 7) Samryanghwajeong, 8) Sosarnjeong, 9) Namcheonjeong, 10) Leehwahaejeong, 11) Kaegeumdang, 12) Geupdang, 13) Nodang, 14) Woonjaednag, 15) Chungdang, 16) Suktoodang, 17) Gwidang, and 18) Soogun. The numerical strength, which the Shilla maintained at the year of A.D. 660, was total 106,353 persons from 35 military units. Shilla committed 57,433 military personnel to combats against the Great Baekche. Ground Forces from the 57,433 personnel were 58,343 persons, and the naval forces were 9,100 persons. Finally, 2,602 persons from among the 9,100 naval forces were only combating forces, and non-combat forces were 6498 persons.

To the extent that CISG and UNIDROIT Principles address the same issues, the rules laid down in the latter are normally taken either literally or at least in substance from the corresponding provisions of the former. Nevertheless, we may find cases where the latter depart from the former. The purpose of this paper is comparison of the two instruments, especially in part of contract formation. The result of this paper shows the fact that in the chapter of UNIDROIT Principles on formation provisions are included on the manner in which requirements that an offer and an acceptance must meet are more comprehensive, and in result a contract may be concluded more easily.

This study primarily concerns the cases recently held as to the formation of contract under the CISG. In order to put forward the most plausible direction to interpret the rules on the formation of contract under the CISG, it particularly deals with the followings. First, it scrutinizes the rules on the formation of contract, focusing on the requirements of offer and acceptance, the time when such offer and acceptance become effective, the issues on the battle of forms. Second, it introduces two recent interesting cases regarding the formation of contract and provides legal and practical advice to the contracting parties when they intend to conclude a contract under the CISG as a governing law. The followings are practical points that the parties should consider when they enter into contract. First, as any signature or intial made in the offer could be regarded as an acceptance, the parties are required to clarify the meaning of such signature or initials before the conclusion of contract. Second, it is not necessarily required one's signature for an offer to become effective but his name. Third, standard terms cannot be incorporated into the contract simply by reference to web-page or other documents. In order for such terms to be incorporated, it may be necessary to enclose them in the offer or to bring the other party's attention to them. Forth, one should remember that an acceptance by act become effective not when such act is complete, but when it is performed.

This study mainly deals with a recent case held as to the formation of contract under the United Nations Convention on International Sale of Goods(CISG). In order to analyse the fact of the case and the justification of its holdings, it examines the rules on the formation of contract under the CISG, focusing on the requirements of offer and acceptance, the time when such offer and acceptance become effective, the issues on the battle of forms. In addition to these, it particularly investigates the rules on a delayed acceptance under the CISG. After looking into those rules, it criticizes the holdings and provides legal and practical advice to contracting parties who intend to conclude a contract under the CISG as a governing law. It finds that whose e-mail in the case amounts to an offer and an acceptance is depended upon the interpretation of intention of the parties expressed in their statement. According to such interpretation, even if a purchase order is requested by the seller for the formation of contract, a contract may be concluded by a simple statement which commits the buyer himself to purchase the seller's goods. This is particularly the case where such request is made only to clarify the buyer's intention to purchase them.

It becomes a common feature of business practices in International Trade to use a standard terms for the formation of their contracts. However, because of differences in legal systems, business practices and so on in their own countries, there have been many conflicts and disputes happening between parties concerned in International Trade. The CISG, which has long been used as the governing law in many cases of International Trade, could not be free from those conflicting issues in its usage and application. This study analyzes the "Black Letter Rules" which was adopted by CISG Advisory Council in 2013 to provide an effective way of resolving the conflicting issues regarding the inclusion of standard terms in International Trade Contracts under the CISG. This study scrutinizes, the relevant rules and requirements for the inclusion of standard terms into a contract. It also deals with the offeror's duty of making clear reference to the standard terms, transmitting the contents of standard terms to the other party. As the other rules for the inclusion of standard terms, this study reviews the principle of denying the inclusion of standard terms after the formation of contracts, exclusion of surprising or unusual terms, preference of individually negotiated terms to the standard terms, contra preferentum rule and preference of the "knock-out rule" to "last-shot rule" in resolving the issue of so called, "Battle of Forms." Lastly, on the basis of analyzed opinion, this study suggests the practical implications for the people working at International Trade-related business sector to facilitate International Trade.

The purpose of this study is to understand the architectural space of Chimjeon (寢殿), the King's Bedroom, and Backyard, in the early Joseon Dynasty. The Royal palace can be divided into three parts, political space for King, living space for King and his family and government office. So first, we should to understand the characteristics of each space in the Royal Palace. Up to now we have looked at the architectural space of the King's Bedroom in the central area and Backyard in Gyeongbokgung (景福宮), one of the Royal Palace, the result of this study is as followings. Cheonchujeon (千秋殿) and Manchunjeon (萬春殿) were not both sides of Sajeongjeon (思政殿), were on the north side of Gangnyeongjeon (康寧殿) Gangnyeongjeon was not a bedroom for the King and Queen, only for King. Bedroom for Queen was located another space in the Royal palace. There was Hamwonjeon on the west side of Koytaejeon. Jamidang and Cheongyeonroo were on the right side of Koytaejeon The Backyard on the north side of Gyeongbokgung had a wide area for horseback archery and the practice of battle formation The arrangement of the King's bedroom in the central area was assumed like as the Fig 7. and Fig 8.

The positions of vessels in JTIDS where each vessel broadcasts its position, can be found using the relative navigation method. Besides positioning, the relative navigation could be adopted for identification friend or foe, tracking targets, monitoring battle field and etc. In this paper, we have explained the fundamental operation and technical structure for the relative navigation and implemented the simulation platform to evaluate the basic function and performance of the system in arbitrary environment. Using platform, the availability of relative navigation within the group network and the characteristic of the algorithm for position prediction was verified. Based on the simulation result, it was verified that EKF based navigation algorithm could produce great initial error and need quite convergence time. To improve the performance, we proposed a new navigation algorithm which uses the minimum norm estimation algorithm until the EKF converges. The simulation results reveal the relative navigation can be effectively used in the formation flight and collision avoidance system.
