This paper focuses on the study of a development direction of the industrial security Expert system. First of all, in order to manage Industrial security system, we need to have law, criminology, business and engineering professionals as well as IT experts, which are the multi-dimensional convergence professionals. Secondly, industrial organizations need to have workforce who can perform security strategy; security plan; security training; security services; or security system management and operations. Industrial security certification system can contribute to cultivate above mentioned professional workforce. Currently Industrial Security Expert(ISE) is a private qualification. However, the author argued that it have to be changed to national qualification. In addition, it is necessary that the system should be given credibility with verifying the personnel whether they are proper or not in the their field. In terms of quality innovation, it is also necessary that distinguish the levels of utilization of rating system of the industrial security coordinator through a long-term examination. With respect to grading criteria, we could consider the requirements as following: whether they must hold the degree of the industrial security-related areas of undergraduate or postgraduate (or to be); what or how many industrial security-related courses they should complete through a credit bank system. If the plan of completing certain industrial security-related credits simply through the credit bank system, without establishing a new industrial security-related department, has established, then industrial security study would be spreaded and advanced. For private certification holders, the problem of the qualification succeeding process is important matter. Additionally, it is necessary to introduce the certifying system of ISMS(Industrial Security Management System) which is a specialized system for protecting industrial technology. To sum up, when the industrial security management system links the industrial security management certification, industrial security would realize in the companies and research institutions dealing with national key technology. Then, a group synergy effect would occurs.

Along with hardware implementation of cultural arts, the importance of cultivating and securing professionals who are able to operate and mange it from the political perspective is highlighted as a political issue. In addition, with growing public demand for culture, performing arts are enlarged and professionalized, and this increased the number of large-scale musicals and activated exchanges with overseas performances, which raised the demand for personnel of performing technology. Like this, growing theaters require professionals in the performing technology field for technically safe and quality performance. The certification system for performing arts professionals is to develop quality of theaters and performing arts by increasing vocational professionalism and safety in the performing technology field. This system performed since 2000 is getting positioned, and employees who worked for the performing technology field at this time showed a lot of attentions with certainty they would receive credit for artistic professionalism and raise pride as a performing arts professional. However, the government's political strategy to secure professionals of cultural arts and interest in human resource(HR) policy in the performing arts field were relatively insufficient. Therefore, this study examined the problems by looking into actual conditions regarding operation and role under the initial purpose of the certification system, and purposed the improvement plan as a first certification system to cultivate Korean performing arts professionals.

Nanotechnology has been growing constantly and it is becoming the leading technology in scientific research and development. Although nanotechnology has important applications in broad variety of fields without boundary of any particular industrial area, the study of nanotechnology related to its commercialization has been conducted in a few ways. To put that figure in context, this study investigates public and expert perceptions about negative potentials of nanotechnology. Through a series of surveys with public (N = 541) and experts (N = 62), we analyzed about public willingness to pay for nano-applied products. Survey results showed that public and experts preferred nano-applied products in the order of electronics, cosmetics, and food and medicine. Experts express high payment intention to electronics rather than public intention. In addition, the survey results showed the purchasing intention of both public and expert group was affected by the attributes of nano-applied products in the order of risk fatality, risk chance, certification, and labeling. But experts put more importance in risk fatality than risk chance comparing to public. Through the case analysis of the effects of labeling and certification, we revealed either labeling or certification can induce both public and experts to buy the nano-applied products with high risk chance and low risk fatality. However, for the nano-applied product with high risk fatality and low risk chance, both labeling and certification are simultaneously required to make customers have positive purchasing intention. The result of this study could be utilized for the nanotechnology-based company to get the consumer behavior information about nano-based product and to establish their marketing strategy.

The purpose of this study is to analyze research trends in post-occupancy evaluation and to identify its Improvement strategy. Also this study suggests historical development of domestic researches on POE and current discussions to POE in architectural fields. The results were as follows. In Korea, 55 papers on POE method were published from 1990 to 2010. In the 1990s, with the introduction of POE method, researches focused on its potential or limitations and presented the barriers to the adoption of POE. In the 2000s, POE researches mainly were apartments evaluation researches by residents' satisfaction. Designers and construct companies feel it is necessary to perform POE, indeed it is difficult to find POE researchers and utilize POE data. Nevertheless, some of them have performed POE of their building and got feedback from residents. In conclusion, it is necessary to minimize the barriers to adoption of POE and to develop its potential. Therefore, it should be performed POE by stakeholders and POE data would be provided a variety of types. Furthermore, POE certification system should be designed at the government level. Basically, POE courses must be included in the architectural curriculum.

To resolve overload in a distribution system, a distribution system operator (DSO) often performs a load transfer using normally open tie points and switches in the distribution line. During this process, the distribution system is momentarily operated in closed-loop operation. A closed-loop current in the distribution system can cause a power failure due to excess breaking current in the circuit breakers and reclosers. Therefore, it is necessary to calculate the closed-loop current exactly. However, if there are a large number of distributed generation (DG) systems in the distribution system, such as energy storage systems (ESS), they might obstruct the closed-loop operation based on bidirectional power flow. For quick and precise operation of a closed-loop system, the ESS has to regulate the power generation while satisfying closed-loop operation in the worst cases. We propose a strategy for balanced power regulation of an ESS. Simulations were carried out using PSCAD/EMTDC, and the results were compared with calculation results.

Unlike an AC system, a DC system does not cause problems with synchronization, stability, reactive power, system losses, and cost. However, more research is still required for the application of DC Systems. This paper proposes a stable black-start strategy for a stand-alone DC micro-grid, which consists of an energy storage system, photovoltaic generator, wind-turbine generator, diesel generator, and DC loads. The proposed method is very important for avoiding inrush current and transient overvoltage in the power system equipment during restoration after a blackout. PSCAD/EMTDC software was used to simulate, analyze, and verify the method, which was found to be stable and applicable for a stand-alone DC micro-grid.

This article indicates that the perceptions on the quality of agro-food are socially constructed. Farmers who were producing red pepper in Eumsung county had somewhat different perceptions on the quality of red pepper according to their own marketing channels. Farmers who were selling their red pepper to consumers by direct marketing tend to think the quality attributes more important as follows; information on producers, ingredients, taste and smell, amount of pesticides input, cleaning the harvested red pepper, quality certification by public authority, and brands. Consumers tend to think safety and production area more important, while farmers tend to think the quality attributes as follows; taste, color, variety, soil environment, and largeness. Based on these research findings, we can give some recommendations as follows; 1) the agricultural extension organization in the Eumsung county should change the strategy for local agriculture towards quality management of red peppers. and 2) the local government need to examine the feasibility of quality certifying on red pepper.
