The Purpose of this study is to exmaine fundamental problems of Gwangyang Port and draw up plans of its Hub Port. Gwangyang Port has been gradually reduced container cargo increase rate. on account of large development of Chinese Port, undevelopment of Hinterland, Port facilities of Gwangyang Port. We should develop hinterland to be closely connected with Port Cluster, Business City, Free Economic Zone to increase cargo volume. and in order to increase transshipment cargo volume, We should prepare diverse plans that can induce Chinese and Japanese transshipment cargo. Gwangyang Port and Busan Port should be managed united one port system by a Port Authority to strengthen international competitiveness. Activation of new ports for the most part call for full support by Government at the beginning. Gwangyang Port's future it can be if Government has strong will.

Korean government has endeavored to increase the exportation of agro-food, and the exporting processed food is one of the main concerns. However, there is little research to promote the exportation of Korean processed food, which is discussed in this paper. This paper analyzed the current situation of the exporting processed food and the government policy in Korea, and presents the strategy to increase the exporting. First, government programs should consider the market efficiency. Second, specified marketing strategies need to be developed after the overall analysis about the world market. Third, governmental support for product development and promotion should be expanded. Forth, efforts to increase the efficiency of logistics and food safety need to be magnified.

The 150 gal Ion EFT(External Fuel Tank) used to enlarge the aircraft operation range was adopted an import equipment in T-50 FSD phase. But in Production phase the EFT was planed to develop for the stable ILS(Integrated Logistics Support) and technical ability improvement by using the composite materials. The design for configuration and fuel system is intended to maintain compatibility with aircraft systems and the development test is performed on component, assembly and aircraft. This study is conducted to provide the technology of design and test for the 150 gallon composite EFT in LRU level. The test results show that the composite EFT is satisfied with structural, functional and environment requirements which are described in specification.

Today's environment of enterprise is changing, They have to face customer' demands with the right product, the right service and supply them at the right time. And also cut down logistics and inventory cost and bring up the profit as much as they can. This means the change of putting enterprise first in importance to putting customer first importance. therefore to correspond to customer's demand, shorting lead time is becoming a essential condition. The answer to this changes of environment is supply chain management. In this paper, It consolidates the necessity on a LTV(Life Time Value) and analyzes data which is concerned of Customer Value. Under the these environments, defines the LTV(Life Time Value) rule that can improve the customer value. We solved this problems using AHP(Analytic Hierarchy Process) for consistency at relationship matrix, AHP(Analytic Hierarchy Process) is based on Saaty's consistency rate. If consistency rate is under 0.1 point, preference rate's weights are acceptable. This study develop a program for AHP weights and support Satty's consistency rate.

In general, weapon systems require very high reliability. Recently Korean defense reliability technologies growth rapidly. However, there are some matters of reform in reliability management, reliability assurance, and defense acquisition environment, etc. In this paper, we propose the reliability development plan for Korean defense system as follows; 1) reliability improvement programs for each acquisition stages, 2) reliability improvement methods for logistics support, 3) reliability improvement programs for developers and manufacturers, 4) reform matters for the defense acquisition law, 6) establishment of defense reliability assessment center and defense reliability committee.

최근 대용량 스트림 데이터에 대한 요구사항이 발생하고 있다. 이때 모든 대용량 스트림을 실시간으로 좋은 서비스를 제공하는 것은 실제적으로 불가능하다. 즉 대용량 스트림 데이터에 대한 QoS(Quality of Service: 서비스 품질)이 중요한 이슈가 되고 있다. 이러한 QoS를 정의하기 위해서는 센서 스트림 데이터에 대한 우선순위 부여방법이 가장 원천적으로 중요한 사항이 된다. 현재 센서 네트워크상에서의 서비스 품질은 연구되고 있지만 미들웨어 레이어에서의 우선순위 부여 방법에 대한 연구가 미비하다. 센서 스트림은 자체적으로는 우선순위를 가질 수 없으므로 사용자 질의 우선순위와 센서 스트림의 발생 시간등을 고려하여 대용량 센서 스트림에 대한 우선순위를 부여하는 방법을 제안한다.

Inchon Port is the second largest import-export port of Korea, and has the point at issue such as the excessive logistics cost because of the limits of handling capacity and the chronic demurrage. The purpose of this paper is to develop the simulation program as a long-term strategic support tool, considering the dual dock system and the TOC(Terminal Operation Company) system executed since March, 1997 in Inchon Port. The basic input parameters such as arrival intervals, cargo tons, service rates are analyzed and the probability density functions for these parameters are estimated. From the simulation model, it is possible to estimate the demurrage status through analyzing various scenarios and to establish the long-term port strategic plan.

There is a possibility of failure as a result of field application in the planning and execution process to change the operating policy for operating terminals, so a lot of time and effort are required to reduce trial and error. In the planning stage to change the terminal operation policy, simulation technology can be used to support decision making. This study introduces a case of using a virtual terminal system among simulation technologies.

In this paper, an algorithm for approximating zeros of sum of three monotone operators is introduced and its convergence properties are studied in the setting of 2-uniformly convex and uniformly smooth Banach spaces. Unlike the existing algorithms whose step-sizes usually depend on the knowledge of the operator norm or Lipschitz constant, a nice feature of the proposed algorithm is the fact that it requires only a diminishing and non-summable step-size to obtain strong convergence of the iterates to a solution of the problem. Finally, the proposed algorithm is implemented in the setting of a classical Banach space to support the theory established.

Family tourism has become the mainstream demand of the tourism market, and it is also an effective way to obtain happiness. This paper takes family tourists as the research object, takes the family tourism family affection interaction behavior and the experience value relationship as the link, Empirically tests the family tourism "interaction behavior-social support-experience value" conceptual model and the relationship hypothesis. The results showed that interaction of family affection had a positive and significant effect on the functional, cognitive and emotional experience value of family tourists. Family interaction in family tourism has a significant positive impact on social support. Social support has significant positive effects on functional, cognitive, emotional and overall experiential values. This conclusion expands the theoretical and empirical research on the relationship between interaction behavior and experience value, and provides a basis for understanding the interaction behavior and experience value of family love from the perspective of tourism experience essence.
