The purpose of this paper is to investigate CFZ(custom free zone) and FTZ(free trade zone) in Korean FTZ System and develop Masan Port in Korea Local Port. The main point of this discussion is to approach the efficient method ill developing Masan Port through comparison CFZ and FTZ. For this purpose, this paper is searched the present situation of logistics in Korea and Northeast Asia, also discussed the concept of FTZ in international status. Then CFZ accepted by Korean government started from the concept of FTZ and is the logistic-centered FTZ in the middle of three model, production-centerde model, production-logistic combination, and logistic-centered FTZ. But CFZ in centering logistic excepted the fundamental manufacture in Korean production. and is almost the same about other various sides, i. e. law and enforcement ordinance. etc This problem is decreasing the efficiency in Korean commercial system. Thus this paper indicate the view point and rightness of region economic through study of FTZ and CFZ in Masan Port. This paper says that FTZ is better then CFZ in Masan Port with comparing superior position about economic development direction, industrial structure, Foreign investment attraction, business fluctuation, national-local renovation. Therefore this paper concludes that the development of Masan Port needs the effort as follow : first, Masan Port must apply in enlarging FTA into Free Tree Area. Second, the government must develop the high-density and medium-small scale in Masan Port. Third, the local government must promote the amount of demand in Masan Port logistic. Forth, the government must actively propel great-sphere development in present Masan Port.

The background of the research is the following. With the prosperity of drone industry, the government has been actively promoting measures to nominate 'drone photographing free areas'. However, existing laws, and procedures are rather unclear with related environmental factors in discordance with one another. Hence, voices in need for establishing a clear precondition for nominating drone photography free area have been rising. The purpose of the research is to provide measures for the preconditions to establish photography free areas for convenient drone photographing. The research utilizes literary methods, conducting focus group interviews to coordinate with specialists who can participate and discuss so that they can provide improvement measures. The research renders improvement measures in different sectors including 2x items in aviation security law, 8x items in free area nomination and procedure, 4x items in infrastructure establishment and information management area. The expected effects are the following: by attaching drone photography with aviation security law, nominating photography free area can be linked up with the Ministry of Land Infrastructure and Technology. Secondly, by enlarging photography restricted area to upper mid-air, a three dimensional drone security will be possible. Thirdly, by providing a 'Yongin area standard model', free area nomination will become more easy. Future research will focus on enhancing aviation security law regarding drone photographing. In addition, the promotion to nominate free areas for 33x responsible areas in accordance with the National Intelligence service will be required.

This paper presents animation techniques and issues involved in virtual environments where the participants interact with each other through a network. The state of the participant should be collected at each local site, and broadcasted to the other sites. Because information exchange is minimal, animation techniques are applied to convert the incoming low DOF parameters into high DOF joint angles that completely determine the configuration of the agents at each frame. As a case study, a software system VRLOCO is introduced, which has been developed by the author over the last five years.

A new meshless method for obtaining natural frequencies of arbitrarily shaped plates with the free boundary condition is introduced in the paper. In order to improve the characteristics of convergence and accuracy of the method, a special local polar coordinates system is devised and located for each of nodes distributed along the boundary of the plate of interest. In addition, a new way of decreasing the size of the system matrix that gives natural frequencies of the plate is employed to reduce the amount of numerical calculations, which is needed for computing the determinant of the system matrix. Finally the excellence of the characteristics of convergence and accuracy of the method is shown in several case studies, which indicate that natural frequencies by the proposed method are very accurate and converged swiftly to exact values as the number of boundary nodes increases.

This study was conducted in order to develop inter-local cooperation strategies between the City of Incheon, in Korea, and three provinces in northeastern China. We begin with a description of the history of and prospects for trade between Korea and China, an explanation of the current economic status of Incheon, statistics on the economy, trade and investment trends in the region, and information on the ports of the three Chinese provinces. The following strategies are suggested for inter-local cooperation based on the current circumstances. First, cooperative industrial strategies and economic investment for promoting the mutual concerns and interests of China and Korea were developed. Second, a practical way of utilizing the Incheon Industrial Park located in Dandong, China, was devised to stimulate industrial and investment cooperation.

본 논문에서는 한국어 의존관계 파서의 정확성 및 효율성을 높이기 위해 구구조 내의 지역적 수식 특성을 반영할 수 있는 지역 의존관계의 사용을 제안한다. 의존문법은 자유어순 언어를 잘 설명할 수 있는 장점이 있지만, 전체 문장구조에 관한 의존제약이 너무 미약하기 때문에 단순히 어절간 구문 의존 제약만으로는 원하지 않는 분석 결과가 너무 많이 생성된다. 그러나 자유어순 언어라 하더라도 지역적인 구구조에는 일정한 어순 제약이 존재한다. 명사구, 용언구 등과 같은 구구조를 분석해 보면 수식어의 지배소는 반드시 그 구 안에 있다. 이러한 구조 정보에 기반을 둔 지역 의존관계 규칙을 이용하면 하나의 의존소에 대해서 지배소로 사용될 수 있는 어절의 범위를 제한하여, 원하지 않는 분석 결과를 줄일 수 있다. 한국어는 기본 문장 구조가 그대로 사용되기보다는 하나 이상의 수의 요소들이 첨가되어 보다 긴 문장 구조로 사용되는 경우가 많기 때문에, 본 논문에서 제안한 방법은 시스템 전체의 성능 및 효율을 크게 향상시킬 수 있다. 실험에서는 파싱의 첫 번째 단계에서 지역 의존관계 규칙을 사용하였을 경우 사용하지 않았을 때에 비해서 의존관계의 수가 평균 69% 정도로 줄어들었다.

As the environment for international logistics varies according to the globalization in world economy, world-class seaports are struggling for the position as strongholds in their own block. As a new government begins its own era in Korea, they are positively implementing their strategies at the level of government for making the Korean Peninsula the logistics centre in North-eastern Asia, marking the most of its geographic advantage. As one of those strategies, it plans to foster a specific area as an international logistics base camp in Northeast Asia by activating its logistics industry through inducing multinational logistics enterprises. In reality, however, in order for Busan seaport, the late-comer, to induce investment from the world-class multinational companies, a considerably large volume of investment should be given from both central and local governments. Accordingly, the objective of this study is to assess its competitiveness and to suggest an activation plan for BSDFA(Busan Seaport Duty-Free Area), based upon the results of on-the-spot interviews in China and Japan. The survey for the respondent's preference by way of Conjoint Analysis indicated that Investment procedures and limitations get the highest 36.2％ preference, so the most critical strategy to be considered for attracting enterprises into DFA(Duty-Free Area) is to solve the problems related to the investment procedures and limitations. The simulation analysis results for market share showed that UAE has the highest preference and BSDFA the lowest preference among the five countries. However, when the levels of investment procedures and limitations and production costare upgraded, the competitiveness of BSDFA was elevated next to that of UAE among the 5 countries. Thus, in order for BSDFA to obtain competitiveness, it is implied that production cost level as well as investment procedures and limitations level, should be lowered so that it could meet companies' demand.
