This paper proposes a mathematical modeling-based approach for assessing disaster effects and selecting suitable mitigation alternatives to provide humanitarian relief (HR) supplies, shelter, rescue services, and long-term services after a disaster event. Mitigation steps, such as arrangement of shelter and providing HR items (food, water, medicine, etc.) are the immediate requirements after a disaster. Since governments and non-governmental organizations (NGOs) providing humanitarian aid need to know the requirements of relief supplies and resources for collecting relief supplies, organizing and initiating mitigation steps, a quick assessment of the requirements is the precondition for effective disaster management. Based on satellite images from weather forecasting channels, an area/dimension of the disaster-affected zones and the extent of the overall damage may often be obtained. The proposed approach then estimates the requirements for HR supplies, supporting resources, and rescue services using the census and other government data. It then determines reliable transportation routes, optimum collection and distribution centers, alternatives for resource support, rescue services, and long-term help needed for the disaster-affected zones. A numerical example illustrates the applicability of the model in disaster mitigation planning.

한국 해군은 함정 내 지휘, 통제, 정보 전달을 위해서 함내외 통합통신체계(ICS)를 구축 및 운용해 오고 있으며, ICS의 주장비는 대부분 외국 제품을 도입하여 운용해 왔기 때문에 군수지원 부족, 군사기밀 유출 등의 문제가 있었다. 본 논문에서는 이러한 문제점들을 해결함은 물론 IP 및 멀티미디어 기반 서비스 등 다양한 함정 내 미래통신 요소를 통합 운용할 수 있도록 개발된 국산 ICS에 대한 개발요건 및 주요 적용기술에 대해서 서술한다.

Purpose: This paper aimed to study the current locations of post offices to analyze service coverage area for parcel delivery in the Eastern Economics Corridor (EEC), which must be considered in the last mile to extend delivery service for e-commerce growth. Thailand Post was the case study in this paper. Research design, data and methodology: To involve solving the delivery service area under the last mile condition, the authors proposed a network analysis to determine service radius by employing a Geographic Information System (GIS). Furthermore, this paper applied Dijkstra's algorithm as a network analysis tool from GIS for analyzing the last mile service coverage area in a new economics zone. At the same time, the authors suggested an approach as a solution to locate last mile delivery center in EEC. Results: The results of the study pointed out that Thailand Post should consider more last mile delivery centers in EEC to support its express service in urban areas as well as improve the efficiency of service coverage for parcel delivery and create more advantages against competitors. Conclusions: This paper proposes a network analysis to extend the last mile service for parcel delivery by following Dijkstra's algorithm from GIS and a solution approach to add more last mile delivery centers. The results of the research will contribute to boosting customer satisfaction for last mile delivery service and enabling easy accessibility to a service center in EEC.

Purpose : The purpose of this study is to analyse affecting factors of Test and Evaluation and to improve the institution of Test and Evaluation in the Domestic purchase program. Methods : The domestic acquisition program is currently small in terms of size, but it is gradually increasing every year. Still, the domestic purchase program has insufficient regulations and procedures compared to the other procurement methods including research & development. Various problems are likely to occur between test and evaluation group, and defense industries regarding the regulations during Test & Evaluation. Therefore, the regulations and methods need to be amended to upgrade the current domestic purchase program into an effective and flawless one. In this paper, six variables have been chosen by the help of experts working in Ministry of National Defense (MND), Joint Chiefs of Staff (JCS), Army Headquarters and DAPA. Results : The six variables are effectiveness of proposal evaluation, fairness of test and evaluation, sufficiency of operational capabilities, seasonal period of test and evaluation, fulfillment in Integrated Logistics Support (ILS) of the industries, and guaranteeing appropriate environment for related enterprises' participation. Conclusion : This paper can help defense industries to enhance their development capabilities, and to perform tests more fairly and effectively considering the key factors identified in this research.

This research is to investigate the effect of the improvement of investment environments with investment incentive on Korean national economy by looking into the foreign investment support system in Korea. To this end, first research model was set up based on our literary study and case study was conducted on 150 foreign companies that were located in industrial complex for foreign companies, received the tax benefit and government subsidization. And it was found that even though the foreign companies were contributing to the national economy in general such as in the area of production, export, employment, development of technology, there was no significant contributory difference between the investment incentive beneficiary and non-beneficiary foreign companies. Therefore it deemed reasonable to reconsider the way Korean government supports foreign companies in Korea and to reinforce foreign companies' relevance to national policy agenda with additional incentives to foreign companies located in comparatively less developed areas. As a way to promote foreign investment, promotion of investment infra such as improvement of follow-up services, openness to foreign investment, industrial deregulations in capital area, revitalization of free economic zone, efficient system to promote foreign investment and the reinforcement of public relations were considered necessary, especially the upgrading of economic structure and the integrated management of domestic and foreign investors deemed necessary for the optimal distribution of the industries.

The Korea China FTA was signed on June 1 2015. It includes some concessions regarding major export items in the manufacturing sector for the protection of primary industries and preferential tariffs for a number of products produced in the Kaesong Industrial Complex. Primary industries are what the Korean government paid the greatest attention to. Rice was excluded from the negotiations from the get go, and was joined by 548 other food items including pork, apples, pears, beef, chili, garlic etc. These foodstuffs account for about one-third of the agricultural and livestock products that Korea produces, and are not going to be subject to tariff elimination. The results of the study are as follows: Korean government policy is to maintain of agri-food export support system, eliminate of agri-food non-tariff barriers, foster of agri-food export SMEs and expand of investment of foreign agri-food company. Korean firms strategy is to establish of regional marketing strategy, ensure of high quality agri-food and develop of food packaging technologies, establish of agri-food export logistics center and take advantage of the FTA preferential tariff.

The air cleaning unit of K00 IFV(or Infantry Fighting Vehicle) has important roles to make sure the engine of the vehicle works precisely as filtering foreign substances in the air such as dust and sands. The entire components including scavenge fan which is one of the important inner part of the air cleaning unit are developed so that we can produce it domestically and don't need to import it from P^⁎⁎ Co., the original maker in United Kingdom. This paper introduces a few verification processes including cleaning efficiency and reliability. As this core unit has developed successfully the improvement of military strength and logistics support can be expected. And design capability, manufacturing skills, maintenance ability of tracked weapon system will be increased thanks to the accumulated technical knowledge obtained from this developing project. Foreign currency savings and reducing operational cost can be expected as well in military industry.

유비쿼터스와 퍼베이시브 환경에서의 위치인지 기술은 자동차 내비게이션, 지능형 로봇, 대화형 가상 게임, 물류 서비스, 그리고 자산 추적 등 다양한 응용 기회를 제공해 주고 있다. 더욱이 위치 인식 정보뿐 아니라 객체 혹은 센서 노드 주변의 상황 정보까지도 전달하여 제한된 공간에서의 다양한 응용에 활용될 것으로 보인다. 그러나 위치 측정에 있어 환경적 요소와 측정 매체 등에 의해 간섭이라는 문제점을 갖는다. 특히 실내 좁은 공간에서 비컨 신호간의 간섭은 거리 측정의 심각한 오류뿐 아니라 더 나아가 위치 인식 시스템 전체 성능에도 영향을 미치게 된다. 이러한 간섭 문제점을 해결하기 위해 본 논문에서는 비컨의 초음파 및 RF 신호 세기를 각 노드 별로 차별화하는 방식인 EEM을 제안한다.

최근 컨테이너 터미널의 관리자들은 안벽의 생산성을 높이기 위해서 양 적하를 동시에 할 수 있는 더블 사이클이나 듀얼 사이클을 시도하고 있다. 하지만 실제 터미널의 데이터를 이용하여 듀얼 사이클을 발생시켰을 경우 YT(Yard Tractor) 배정 방법이나, QC(Quay Crane)의 작업의 속도, 야드의 수출컨테이너 위치 등에 따라 효율성이 저하될 수 있다. 특히 기존의 야드 운영방식으로는 듀얼 사이클이나 더블 사이클을 효율적으로 지원하기 어렵다. 따라서 본 논문에서는 실제 터미널에서 듀얼 사이클을 사용할 때 효율성을 더 높일 수 있는 터미널야드 운영방법을 제시한다. 모형은 시뮬레이션 분석 소프트웨어인 Arena를 이용하여 수립되었다.
