PURPOSES : Expressways experience chronic and recurring congestion, especially during weekends and holidays, because of the increased demands for leisure-related travel. The alternatives to solve chronic and recurring congestion may be three-fold: (1) physical expansion of expressway capacities, (2) road pricing, and (3) temporal and spatial distribution of traffic demands. Among these, the third alternative may be the most cost-effective method for the Korea Expressway Corporation (KEC) that can be achieved by using the existing ITS infrastructure. METHODS : KEC initiated a pilot study in which the traffic on congested expressways was managed by providing traffic condition information (i.e., travel times) of neighboring national highways for taking detours via variable message signs (VMS). This study aimed to estimate the detour rate, and the two pilot studies on Seohaean and Yeongdong expressways yielded many benefits. RESULTS: It was revealed that the total length of congestion segments decreased by 7.8 km, and the average travel speed increased by 5.3 km/h. CONCLUSIONS: Based on these findings, it was concluded that the propagation of detour information via VMSs during congestion hours can help reduce congestion on expressways and increase the benefits of the entire network.

본 연구는 한국 해군의 해난구조능력 향상을 위해 임무수행의 주요 수단이 되는 잠수체계를 개선하는 방안에 대한 연구이다. 특히 구조작전시 잠수체계별 임무 가능구역이 제한되는 문제를 해결하기 위하여 이동식 포화잠수 체계를 중심으로 연구를 진행하였다. 연구는 먼저 임무의 범위를 확인하였고, 기존 연구결과와 현용 잠수체계를 분석한 결과를 활용하여 이동식 포화잠수체계의 요구조건과 표준구성을 정리 및 제안하였으며, 이동식 포화잠수체계를 활용한 기존 잠수체계의 보완 및 개선 가능성에 대하여 군의 전략 선택 기법인적·가·용 판단에 따라 검토하였다. 또한, 도입방안에 대해서는 상용제품의 해외수입과 국내 개발로 구분하여 장·단점을 분석하고, 설치 및 운용방안에 대해서는 각 플랫폼별로 실효성을 분석하였다. 연구결과로 먼저, 200 m 이상에서 6명 이상의 잠수사가 약 17일 이상 포화잠수를 정상적으로 실시할 수 있도록 요구조건 및 표준구성안을 제안하였으며, 기존 잠수체계의 보완 및 개선 가능성에 대해서는 예비장비 공급 및 병행사용 등 다양한 보완이 기대되나 혼합기체잠수체계를 포화잠수체계로 개선하는 것은 경제성이 떨어졌다. 설치방안은 ATS-Ⅱ후속사업에서 이동식 포화잠수체계를 탑재가 가능하도록 제작하는 것을 제안하였으며 운용은 평시 교육 훈련 및 ARS 대체전력으로 사용하다 전시에 별도의 플랫폼에 탑재하여 추가적인 구조전력으로 활용해야 한다.

Applied magnifying factor to the outputs, the proper number of equipment can be estimated. RESULTS: As a result, proper number of equipment by regional offices were required 28% more than current conditions. CONCLUSIONS: Using the proposed a methodology, fundamental data for scientific and reasonable strategies can be stored as well as be used for the future plan for budget allocation.

This paper’s aim is to suggest the Expert System for analyzing relative combat power in ground operations. Since relative combat power analysis in terms of comparing combat power of friendly forces with one of the enemy can determine how the commander and staffs operate their unit afterwards, it requires fast and rational decision-making process. However, it has relied on manual method so far though Tactical Information Communications Network(TICN) into which numbers of applications can be loaded has been developed over a decade. The Expert System that will be built using EXSYS Corvid tool is expected to lessen error rate, provide faster decision- making, and reflect intangible combat power as well as tangible one by using an appropriate weights in analyzing relative combat power.

This study was conducted to provide strategies for the reduction of plate waste and prevention of plate waste reuse in foodservice operations. To achieve these goals, we surveyed the entrepreneurs of foodservice operations, professionals in the field of foodservice management and food safety, and public officials working for food safety enforcement about their perceptions and strategies on plate waste management. The professionals’ survey indicated that definition of plate waste needed to be clear for understanding. Also Korean food culture insisting on abundance and variety table settings, foodservice owners' demands for cost reduction, and foodservice workers' insufficient safety perceptions were indicated to bring forth the practice to reuse plate waste. The effective ways to control plate waste management were systematic educational supports for Korean food culture upgrade among consumers and improvements of safety perceptions among owners, as well as workers. Also small portion size was needed to reduce plate waste.

Recently, For the most efficient use of spaceis, high-rise buildings tend to increase. So it is with Korea, too. Besides, today high-rise buildings grows due to fire damage to life and property at large. In this study, Through analysis of domestic and foreign fire case and listen to the high-rise building fire managers, tenants, professionals advice, when the fire from the high-rise building, effective fire suppression tactics should we wish to research ways. In addition, we have used the car gondola was installed outside the fire suppression methods in studying. So that fire-fighting is a fire place can be reached quickly, many casualties and property damage, will be reduced.

This paper considers the simultaneously firing model for the artillery operations. The objective of this paper is to find the optimal fire sequence minimizing the final completion time of the firing missions of multiple artillery units for multiple targets. In the problem analysis, we derive several solution properties to reduce the solution space. Moreover, two lower bounds of objective are derived and tested along with the derived properties within a branch-and-bound scheme. Two efficient heuristic algorithms are also developed. The overall performances of the proposed branch-and-bound and heuristic algorithms are evaluated through various numerical experiments.

The process of berthing/deberthing operations for entering/leaving vessels in Busan northern harbor was analyzed and evaluated by using an integrated VTS(vessel traffic service) system installed in the ship training center of Pukyong National University, Busan, Korea. The integrated VTS system used in this study was consisted of ARPA radar, ECDIS(electronic chart display and information system), backup(recording) system, CCTV(closed-circuit television) camera system, gyro-compass, differential GPS receiver, anemometer, AIS(automatic identification system), VHF(very high frequency) communication system, etc. The network of these systems was designed to communicate with each other automatically and to exchange the critical information about the course, speed, position and intended routes of other traffic vessels in the navigational channel and Busan northern harbor. To evaluate quantitatively the overall dynamic situation such as maneuvering motions for target vessel and its tugboats while in transit to and from the berth structure inside a harbor, all traffic information in Busan northern harbor was automatically acquired, displayed, evaluated and recorded. The results obtained in this study suggest that the real-time tracking information of traffic vessels acquired by using an integrated VTS system can be used as a useful reference data in evaluating and analyzing exactly the dynamic situation such as the collision between ship and berth structure, in the process of berthing/deberthing operations for entering/leaving vessels in the confined waters and harbor.
