  • In a nuclear emergency, protective actions for the public should be taken in time. It is internationally proposed that generic intervention levels (GILs) and generic action levels, determined based on cost-benefit analyses, be used as the decision criteria for protective actions. Operational intervention levels (OILs) are directly or easily measurable quantities corresponding to these generic levels. To assess the necessity of protective actions in a nuclear emergency, it is important that the environmental monitoring data required for applying and revising OILs should be promptly produced. It is discussed what and how to do for this task in the course of the emergency response. For an emergency environmental monitoring to be performed effectively, a thorough preparedness has to be made including maintenance of the organization and equipments, establishment of various procedure manuals, development of a supporting computer system and periodical training and exercises. It is pointed out that Korean legal provisions concerning GILs and OILs need to be amended or newly established.

  • This study aims to calculate reasonable carving capacity of the Gwangneung area and to review its tourism policies from the perspective of the tourist's demands. According to the analysis results, The socio-psychological carrying capacity by targeted intervals of time is generally underestimated and less than desired. Parking lots followed by stores and then roads are the biggest issues weighing down the area's carving capacity Also, another finding shows that the physical carrying capacity, analyzed based on area use, is estimated for 600 tourists and 130 cars. This study recommends following that Gwangneung establish various tour programs linking its cultural and historical sites to forest and ecological resources. Further to this, Gwangneung might be better off exerting efforts to developing environmental education programs and training more cultural and ecological guides. The findings necessitate that should be made off limits to cars, and instead servicing the area with shuttle buses. Management offices can also be classrooms used for cultural, historical and ecological education and exhibitions. Other findings suggest an expansion of convenience facilities such as more potable water stations, benches, resting areas and a continued monitoring of tourism activities in the area.

  • In the midst of the rising need for Industrial Security experts, the development of National Competency Standards(NCS) with regards to industrial security is a very important and urgent task. The NCS standardizes university-level academic curriculum and qualification systems and connects them with the industry's needs. This study has extracted, classified and analyzed security-related jobs and tasks requiring security expertise that is required within NCS. Through this study, many tasks have been confirmed to require security competencies that are different from those in IT-security, physical security that already exist as a NCS tasks. It is expected that the industry's needs of industrial security expertise will be reflected in future NCS development, which will be used as basic data for systematizing industrial security jobs and competency.

  • The use of RaspberryPi in building an embedded system may be difficult for users in understanding the circuit and the hardware cost. This paper proposes a solution that can test the systems virtually. The solution consists of three elements; (i) editor, (ii) interpreter and (iii) simulator and provides nine full modules and also allows the users to configure/run/test their own circuits like real environment. The task of abstraction for modules through the actual circuit test was carried out on the basis of the data sheet and the specification provided by the manufacturer. If we can improve the level of quality of our solution, it can be useful in terms of cost reduction and easy learning. To achieve this end, the electrical physics engine, the level of interpreter that can be ported to the actual board, and a generalization of the simulation logic are required.

  • The purpose of this study is to prevent school safety accidents by conducting an analytic investigation on safety accidents that occur in elementary, middle and high school during 2010-2014 in Chung-Nam. We used the status of safety accidents in school based on the Chung-nam School Safety and Insurance Association database. Data was analyzed by descriptive Statistics. It was found that the incidence of safety accidents in school has increased, and in the case of elementary schools it was higher than in middle school or high school. Safety accidents occurred most during break time, and in schoolyard, and due to student's carelessness. Safety is one of the most basic human needs. To decrease the incidence of safety accidents, we need to set up with comprehensive safety system including human, physical and environmental factors. Based on the this study, it needs more wide study on various countermeasures and to determine effects.

  • To solve the large scale optimization problem approximately, various approaches have been introduced. They are mainly based on recent research advancement of simulations for evolutions, flocking, annealing, and interactions among organisms on artificial environments. The typical ones are simulated annealing(SA), artificial neural network(ANN), genetic algorithms(GA), tabu search(TS), etc. Recently the particle swarm optimization(PSO) has been introduced. The PSO simulates the process of birds flocking or fish schooling for food, as with the information of each agent Is share by other agents. The PSO technique has been applied to various optimization problems of which variables are continuous. However, there are seldom trials for visualization of searching process. This paper proposes a new visualization tool for searching process particle swarm optimization(PSO) algorithm. The proposed tool is effective for understanding the searching process of PSO method and educational for students.

  • The history of design has been closely related with the development of technology. The digital revolution requires design to be as innovative and inventive as the Industrial Revolution had been. In the current society demanding innovation and a new role for design, a successful result can be obtained in the interrelationship between digital and physical environments. In this point of view, exhibition design as a part of space design has had the method of analogue virtual reality, which induces spectators' experiences by creating a virtual environment, as its main expression means before digital technology was introduced. This method was developed from plane images or models to picture techniques according to the development of media technology. Nowadays, the exhibition method introducing multimedia, which enables interactions, is being developed. The main purpose of this study is to identify the meaning and role of virtual space in the view of space design and to analyze its functional interaction. Through this, it attempts to actively promote organic integration and development of widely used cyber space and traditional space design.
