9.11 This research since 2001, including shipping and port security and cargo flow international logistics the overall efficiency of the important issues of the international community that reflects the emerging research on the logistics to improve the security problems of I may occur in the logistics sector in the country, such as terrorism and to prevent security incidents from the security system of the logistics in order to operate in real time, and the introduction of advanced logistics and my analysis and logistics for the security system to collect data and develop lesson Logistics problems facing the security sector will want to analyze and improve the present. The analysis of the problems of logistics and security and find ways to improve research and literature selected by experts to improve, and to improve the first part of measures to improve the survey was analyzed through the AHP.

Historically, government has facilitated logistics by building the airports, the seaports, the rail and transit lines, subsidized their operations where necessary, and established the basic laws and regulations pursuant to which the industry serves the public. In the late 1990s and early 2000s, Korean government began to prepare the basic laws of logistics and nowadays it has tried to refine national logistics laws to reflect contemporary industry conditions and evolving ideological attitudes. The policy objectives governing logistics regulation have changed significantly since 2000. This article traces the current status of the Korean logistics laws which regulate one of the nation's most important industries and suggests certain amendment of current laws.

항로추종성능은 자율운항선박(MASS)의 중요한 자율제어기능 중 하나이다. 이는 선박의 안전성을 보장하기 위해 중요하며, 자율운항선박의 설계 단계에서 사전 평가가 필수적이다. 본 연구는 자율운항선박의 항로추종성능 평가를 위한 전산유체역학(CFD) 모델과 LOS 알고리즘 연계 방안을 제안한다. 먼저, 자율운항선박의 정수 중 거리 이탈 편차를 이용한 항로 추종 성능 평가 모델 개발에 관하여 기술했다. 먼저, 항로 추종을 수행하는 선박 주변의 난류 흐름은 비압축성 뉴턴 유체의 가정하에 비정상 RANS(Reynolds Averaged Navier-Stokes) 법을 이용하여 수치적으로 계산되었다. 중첩격자계법을 CFD 모델에 적용함으로써 거리 이탈 편차를 이용하는 LOS(Line-of-Sight) 가이던스 알고리즘에 의한 타의 회전 및 이에 따른 선체의 6 자유도 움직임을 CFD 환경에서 구현하였다. 개발된 자유 항주 선박 CFD 모델을 이용하여 항로 추종 시뮬레이션 평가 결과, 설정된 항로에서 선박의 정수 중 항로 추종 제어는 파도, 조류, 및 바람과 같은 외부 교란의 부재로 LOS 알고리즘에 의한 우현/좌현 측 변침뿐만 아니라 직진 경로의 추종도 성공적으로 수행됨을 확인하였다. 선체, 프로펠러, 타의 복잡한 상호작용을 정도 높게 해석할 수 있는 자유 항주 선박 CFD 모델과 LOS 알고리즘의 결합은 자율운항선박의 항로 추종 성능 평가를 정량적으로 평가하는 데 기여할 것으로 기대된다.

The purpose of this study is to examine the role of safety sheriffs and their necessity in order to improve the activation of safety sheriff's professionalism. Seven security sheriffs were finally selected to discuss their activities and discuss ways to improve their effectiveness. We conducted semi - structured interviews and conducted in - depth interviews with limited data and inadequate prior research. The results of this study are as follows. First, the government should get the help of citizens, citizens and residents. If the state wishes to reduce the number of safety accidents and bring positive results to the public, it should not rely solely on the utilization of institutions. Second, in order to be a safe sheriff with a positive response from the local residents, the activities of the sheriff's sheriff are not only aimed at preventing risks in the environmental domain and reducing the number of accidents, Publicity should be provided to the landlord, tenant, and residents to inform them that the activity is preventive of accident prevention. Third, under the current law, it is necessary to disclose public facilities such as roads, airports, and harbors to the private sector in order to make it possible to monitor school facilities and youth training facilities. Fourth, the safety sheriff is expected to put forward the expectations and positive results of prevention through the beginning of the inspection activities, and the role of the Korean people in becoming psychological stable and efforts to be born as safety experts are required. Finally, it is necessary to establish a concrete manual, strategic safety inspection plan.

Recently the characteristics of those who committed serious terrorist crimes are not directly related to the direct command system of a specific terrorist organization (ex. IS) but are influenced by the political propaganda of terrorist organizations online, Terrorist crime under the loose form of the terrorist organization. Therefore, this study suggests ways to improve countermeasures against terrorism in metropolitan subways. Although it is important for the prevention of terrorism in the subway, it is important for the police officers of the subway police and the special police officers of the railway to have a physical limit to take charge of them, and after confirming that improvement measures are necessary, And pointed out the possibility of establishing independent security departments where judicial and administrative control is not feasible to grant police rights. In addition, I pointed out how to improve the safety of subways in the metropolitan area through the recruitment of core job candidates and the identity survey during the subway operation. Furthermore, it was confirmed that a special council on terrorism, which can take into consideration the characteristics of subway terrorism, such as airports and ports, is required to be established in charge of terrorism prevention under the current Anti-Terrorism Act. Finally, it is once again emphasized that the strengthening of the powers of the counterparts to terrorism must inevitably limit the basic rights of the people, so the principle of proportionality must be observed in their activities.

The purpose of this study was to identify evaluation factors and analyze the relative importance among factors to select a suitable transportation method for transferring the increasing amount of transshipment at multiple terminals at the Busan new port. To accomplish this, the evaluation factors were selected through a literature survey and brainstorming of a group of experts associated with the port operation, and were classified into five major factors and 15 middle factors. The evaluation factors classified hierarchically were surveyed relative to workers in organizations such as shipping companies, port corporations, container terminals, and related ministries. The importance of each factor was calculated using the hierarchical analysis process (AHP). As a result of the importance analysis, priority was assigned in order of safety, productivity, investment efficiency, operational efficiency, and policy conformity. Through this, it was necessary to select a suitable transportation method for the transshipment cargo in terminals while focusing on the cargo and terminal security and preventing accidents. As a result of calculating from six ITT transportation candidates, the priority was determined in order of monorail, Autocon, and so on as ITT transportation suitable for the Busan new port..

This paper proposed several activation strategies at both the government and company parts for the development of domestic third party logistics(TPL) to pull electronic trade era much earlier. In the government side, it must need to arrange and integrate complex regulation rules on the Logistics for more smooth access and use the TPL market. Also, it has to provide multiple support policies such as tax reduction, technical and financial service providing, and logistics information system to TPL. Finally, it should construct the government levels education system to train and forster a competent man who is well qualified as a electronic and logiscic expert. The TPL company must build up a total logistics information system concerned with an innovative operation system such as SCM, JIT etc. which can provide logistic services on demand to the electronic trade customers to maximize consumer satisfaction. In the shipper company level, it try to join a long-term strategic alliance with TPL to reduce logistic cost and increase logistic service to its electronic trade consumers.
