There are some limitations in the analysis and evaluation for area traffic control systems. The area traffic is consist of several intersections interconnected which are very complicated and many traffic strategy are adopted for the control system. This paper features an effective area traffic control system by High Level Architecture(HLA) which is a new developed simulation tool. In this paper, we discuss the design of HLA-based area traffic control simulation. We describe technical motivations for the HLA, the key elements of the architecture and how they are minimum and essential to the goal of reuse and interoperability in simulation arena.

This paper deals with the simulation model for A-Mart logistic center design and operations. In developed simulation model, receiving docks, conveyor sorter, conveyor system, shipping docks, material handling devices and manual sorting stations are considered. Three types of cargo such as transfer center cargo, distribution center cargo and supermarket cargo are considered. The simulation model and process animation are developed using the simulation package ARENA. Among various design and operation alternatives consisting of the number of workers of receiving dock, allocation of receiving docks by cargo types, conveyor sorter velocity, the number of folk-lift, the number of manual sorting operators and overall layout, the best alternatives of each subsystem are selected by simulation analysis. The major performance measures such as sorter throughput, utilization of operators at each station, receiving docks utilization and folk-lift utilization are considered for the alternative evaluation.

Many mid-sized companies in Korean automotive industry have attempted to solve the lack of human power, to control the quality of components, to improve the production rate, and to innovate the manufacturing line. The goals of this study are to analyze the production rate of an automotive component manufacturing line using simulation software, to construct a Flexible Automation Subassembly (FAS) system and to suggest an optimized layout design using FAS line. In this research, the simulation model for manufacturing line was developed and used the realistic data (production planning, component type, working order, process time, queue time, line rules, etc) of a medium sized company in Korean automotive industry. To complete this research, a simulation software 'ARENA' was used.

The electronic bill of lading system replacing with traditional paper B/L has been evolved from SeaDocs and CMI to Bolero system. Therefore e-B/L is considered as an evolving concept rather than fixed one because it has been changed with development of information technology. Bolero system designed to replicate all functions of a paper B/L has some limitation to be utilized as an e-B/L in changing international business arena because it has a centralized model. Therefore it is considered to be important that the current e-B/L operating system needs to be diversified. This paper aims to provide three types of the operating model of global e-B/L to be applied with feasible solution coping with the current problems, which is expected to contribute to the utilization of electronic bill of lading.

It is very important to foresee the main stream of technology development in the future. Packaging related manufacturers in equipment and materials focused their strength on products sharing big portion of world markets. As a result, domestic supply sources for packaging materials and equipment has been increased, but the manufacturer's capital and manpower is so limited to develop high technology machinery and high functional materials. The current status of packaging infrastructures in Korea is reviewed statistically. The hot issues in packaging arena are now in wafer level packaging, 3D packaging, and ultra-thin packaging. In addition, the recent advancement in microelectronics packaging technology is also covered.

In this study, we propose an RFID based container terminal operation process. Field tests are conducted for 900 MHz (truck identification) tag and 433 MHz RFID (container identification/e-seal) tag at an Incheon container terminal to verify possibility of applying RFID in the container terminal gate. To evaluate effect of applying RFID in the container terminal operation, simulation models for current and RFID based container terminals are developed using ARENA. Simulations are carried out using industrial field data and the result indicates that performance of the container terminal can be prominently improved after RFID application.

This study was carried out to investigate women's labor in the private and public spheres in traditional societies from the Three Kingdom Period to the Chosen Dynasty. This study is based on review of historical literature. It was found that women in the traditional societies from the Three Kingdom Period to the Chosen Dynasty worked not only in private places, such as in households as housewives, but also as slaves in public places such as government offices. Also, women as housewives worked not only to fulfill private needs, but also to pay taxes. In this sense, women in traditional societies participated in labor force in the public arena, not unlike women in industrialized societies who participate in labor market. This research provides a piece of counterevidence against the general belief that women in traditional societies only conducted private housework at home. Therefore this study suggests that we need to rethink gender roles in traditional societies.

This study aims to explore the difficulties of evidence-based pharmaceutical policy-making in the Korean context where several pharmaceutical policies were introduced within a short period. Semi-structured in-depth interviews were performed with eight experts in the Korean pharmaceutical arena. The key challenge in Korean situation might be the apparent lack of available evidence caused by the limited resources, the lack of policy consistency and coordination ability in the authorities and distrust across stakeholders. To build an evidence-based tradition, it is essential to resolve the tangible lack. At once, more fundamental changes seem to be required in the intangible policy environments.

To Provide pleasant building environment and the ease of maintenance and facility management, many new office buildings are being built as intelligent buildings. Building control systems which are employed in intelligent buildings require advanced types of controllers and varieties of control schemes. Designing and installation of these types of advanced building control systems take a lot of effort and also they are costly. In order to design these systems, it is necessary for the designers to have means to analyze and estimate the performance of control systems. In this paper, the results of the simulator for HVAC and elevator system are presented as the first stage of the development of the integrated simulator. For the development of simulator, ARENA which is the general-purpose software tool for the simulation with reinforced GUI is used.

Dry docks are used to repair warships or Merchant ships based on their life cycles. There are the certain number of dry docks in the ROK Navy, However, the ROK Navy force structure has been changing a lot since the Korean War. The focus of this study is to analyze the queueing problem regarding present dry docks capacities and to forecast the appropriate number of dry docks based on future naval ship structure. The study proposes to obtain an efficient dry dock size using queueing problem and simulation.
