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.

Numerous deaths and substantial property damage have occurred recently due to frequent disasters of the highest intensity according to the abnormal climate, which is caused by various problems, such as global warming, all over the world. Such large-scale disasters have become an international issue and have made people aware of the disasters so they can implement disaster-prevention measures. Extensive information on disaster prevention actively has been announced publicly to support the natural disaster reduction measures throughout the world. In Japan, diverse developmental studies on disaster prevention systems, which support hazard map development and flood control activity, have been conducted vigorously to estimate external forces according to design frequencies as well as expected maximum frequencies from a variety of areas, such as rivers, coasts, and ports based on broad disaster prevention data obtained from several huge disasters. However, the current reduction measures alone are not sufficiently effective due to the change of the paradigms of the current disasters. Therefore, in order to obtain the synergy effect of reduction measures, a study of the establishment of an integrated system is required to improve the various disaster prevention technologies and the current disaster prevention system. In order to develop a similar typhoon search system and establish a disaster prevention infrastructure, in this study, techniques will be developed that can be used to forecast typhoons before they strike by using artificial intelligence (AI) technology and offer primary disaster prevention information according to the direction of the typhoon. The main function of this model is to predict the most similar typhoon among the existing typhoons by utilizing the major typhoon information, such as course, central pressure, and speed, before the typhoon directly impacts South Korea. This model is equipped with a combination of AI and DNN forecasts of typhoons that change from moment to moment in order to efficiently forecast a current typhoon based on similar typhoons in the past. Thus, the result of a similar typhoon search showed that the quality of prediction was higher with the grid size of one degree rather than two degrees in latitude and longitude.

Fuel oxygenates, such as Methyl tertiary Butyl Ether (MTBE) is additive in gasoline used to reduce air pollution. Gasoline components and fuel additives can leak: form underground storage tanks. MTBE is far more water soluble than gasoline hydrocarbons like BTEX then it travels at essentially the same velocity as groundwater. MTBE in drinking water causes taste and odor problems. Therefore, the purpose of the this study is to examine the ability of ground tire to sorb MTBE in water. The study consisted of running both batch and column tests to determine the sorption capacity, the required sorption equilibration time, and the flow through utilization efficiency of ground tire. The batch test result indicated that ground tire can attain equilibrium sorption capacities about 0.5 mg of MTBE. The result of column test indicate that ground tire has on the 36% utilization rate. Finally, it is clear that ground tire represented an attractive and relatively inexpensive sorption medium for a MTBE. Authors thought that to determine the economic costs of ground tire utilization, the cost to sorb a given mass of contaminant by ground tire will have to be compared to currently accepted sorption media. The cost comparison will also have to include regeneration and disposal cost.

This study tests and reconfirms the wealth transfer of mergers and acquisitions(M&As) by examining the changes in and the relationship between shareholder and bondholder wealth after the announcements of M&As for the publicly listed firms in Korea Stock Exchange and KOSDAQ market during $1999{\sim}2006$. The change in shareholder wealth is measured by the Cumulative Abnormal Return(CAR) at the M&A announcements, and the change in bondholder wealth is calculated using the Yield Spread Change(YSC) and the change in acquiring firms' credit ratings. The empirical tests show that the CAR of 344 sample acquiring firms at the announcement is 3.59%, which confirms results of the prior research on M&As in Korean market. The average YSC for 35 sample acquiring firms between $2001{\sim}2006$ proves to be negative when we use the yield spread of firms with comparable credit ratings as a benchmark, which means that the acquiring firms' bondholders gain with the announcements of M&As. We find the same result using another benchmark-the yield spread of government bonds. The improvement in the acquiring firms' credit ratings one year after the M&As also indicates that the M&As, on average, increase bondholder wealth. Our test results are consistent with those of the existing studies on the effect of bondholder wealth after the M&As in the United States, which shows that the bondholder wealth increases after the M&As. We do not find the evidence that there is a wealth transfer from the acquiring firms' bondholders to the shareholders after the M&A announcements. Rather, this study confirms that the wealth of the acquiring firms' bondholders increases in the M&As in Korea.

Urban development-related growth in recent years has become a qualitative growth based on regional identity, rather than a hardware-based growth. For this purpose, strategic approaches to the value of cultural assets of the city are required for competitiveness of the city. In this paper, I seek a model for urban regeneration and regional development through empirical case studies of cultural assets and utilize the 'Seoul Fairy Tale Festival' in terms of strengthening regional competitiveness. By analyzing detailed elements of the 'Seoul Fairy Tale Festival' case, the hardware infrastructure, software and governance structures, diverse contentsware, ecosystem characteristics centered on the humanware, and circular structure was studied. As a feature of cultural assets, combined with the management of physical assets and operations of several programs, was the basis for creating a synergy effect of creating an identity for the region. In addition, it was confirmed the possibility of a regional-rehabilitation type of urban regeneration that is based on the expansion of existing facilities, and a regional-innovation type of urban regeneration that is based on a fusion of characteristics. This analysis is significant in terms of the possibility of large urban regeneration based on cultural assets associated with the festival, as well as physical assets and by combining various governance stakeholders for the festival, it can be concluded that it provided an indigenous virtuous cycle.

This study was carried out to select new pelleting binder and material for Welsh onion seeds. The optimum treatments of the various plant growth regulators to improve seed germination of the Welsh onion was also estimated. There were no significant effects of growth regulators on the germination percentage, but germination was faster according to the number of days to 50% of the final germination ($T_{50}$) and the mean number of days to germination (MDG) than those of the control. Germinability was increased when the seeds were soaked in gibberellic acid ($GA_3$) solution for 24hrs, even though there was no synergy effect on the germinability when $GA_3$ was mixed with 6-benzylaminopurine (BAP). The optimum treatment for improving germination of Welsh onion was observed when the tested seeds was soaked in 500 $\mu$M of $GA_3$ at $20^{\circ}C$ for 24hrs. Also, when the seeds soaked in the aforementioned treatment, the rate of germination was increased at lower temperature than at $20^{\circ}C$, the optimal temperature. The percentage and the speed of seed germination depended on the kinds of pelleting binder and their concentration. It showed that the higher the concentration of the binder for seeds pelleting, the lower the percentage of seed germination. Among the pelleting binder, polyvinyl alcohol (PVA) and polyvinyl pyrrolidone (PVP) were the best binders for seed pelleting, because seed germination using those binder did not affect on the concentration of binder. On the other hand, Carboxymethy cellulose (CMC) and methyl cellulose (MC) severely inhibited the seed germination The germinability was also different arcording to the pelleting materials. Among the different 58 pelleting materials, kaoline alone, the mixture of bentonite and kaoline, the mixture of bentonite, calcium carbonate and diatomaceous earth #300 were found as the best pelleting materials for welsh onion seeds.

Now, the Korean footwear industry needs the concrete enhancement of its competitive edge for regaining of its previous well known reputation. For this purpose, this study emphasizes the cooperation between the members through the supply chain of Korean footwear industry, as a c-SCM(Collaborative Supply Chain Management) by aid of information system. The key issue will be how well to coordinate operations flow not only through internal process stages, but also through entire external supply chain stages. In other words, the target goal must be the system optimization through the entire supply chain beyond the local optimization of internal supply chain process. We, at first, analyze the traditional structure of supply chain in Korean footwear industry and find out critical problems, and then, we develop the collaborative information framework in conjunction with several collaborative process modules. The suggested collaborative production & supply planning system was designed for sharing information and it is based on ebXML(electronic business eXtensible Markup Language) framework. In this way, the enhancement of the efficiency and competitiveness can be expected through the synergy effect of coordination of information and material flow, the reduction of lead times, and production costs.

The purpose of this study is to analyze how servant service factor of service marketing factors affects to customer's satisfaction, relationship quality, and commitment and consequently to see how these factors affect to revisit intention which is the hotel performance. The empirical results showed that technical factor and customer orientational factor had a significant influence on customer satisfaction and relationship quality, and functional factor affected to only relationship quality. Also customer and relationship quality had a significant influence, and commitment had a significant influence on revisit intention which is a performance factor. Specifically relationship quality built by the interrelationship between the purchasers and the suppliers showed higher influence than customer satisfaction's influence on the commitment. That is, when there is an interaction between trust on the employees and customer satisfaction, there is a greater synergy effect on the commitment. Although the degree of customer satisfaction is low, the commitment can be high with high effort of service providers. This implies that the attitude of service providers is the critical factor on the degree of commitment of service users.

Sunken vessels on major fairways can cause many problems in terms of maritime safety and the marine environment. In order to prevent secondary marine pollution accidents caused by sunken vessels, information on sunken vessels has been collected, a risk assessment has been conducted, and the relevant vessels are being managed according to the results of each assessment. However, there is still a demand for improvements. The most important of the improvement plans is a paradigm shift. In other words, the management of sunken vessels needs to be transformed according to a new paradigm to manage all sunken vessels within three years from the time of sinking. Legislative improvements are also needed for the reporting system for sunken vessels, risk assessment tools, the implementation of risk mitigation measures, and criteria for the implementation cost of risk mitigation measures. In addition, close coordination between marine pollution response and sunken vessel management efforts is needed. As the division of duties between the Korea Coast Guard and the Ministry of Oceans and Fisheries is vague, collaboration between the two ministries is required. Close collaboration is also needed between the departments of navigation safety management and sunken vessel management. Therefore, it is necessary to more clearly establish the relationship between the two systems and create a synergy effect between the two administrative operations using the results of the risk assessment in the Marine Environment Management Act to determine the navigational risk posed by obstacles with regard to the Maritime Safety Act.

This study verified the effects of 'the education and training course for Aestheticians(Skin)' suggested by 'NCS', which is an outcome of the government's efforts to change from an 'educational background-centered society' to a 'capability-centered society' on the 'profession' and 'practice suitability' of actual aestheticians(skin) positively. As a result, three factors except for hygiene-related subjects and basic occupation capability had significant effects on the practical capability, and 4 factors except for the 'basic occupation ability' had significant effects on the 'profession' of skin beauticians. This suggests that people understand as a concept related to professionalism, even though hygiene-related subjects are associated with the customer's health, so it is very important. This means that awareness should be exchanged from practical capability, not professionalism, for hygiene-related subjects. In addition, the basic occupation capability is difficult to acquire for a short time and is organized by the capabilities, which are expected to have synergy effects when combined with professionalism knowledge. Therefore, it is necessary to prepare concrete measures to cultivate the basic occupation capability. When the government currently presents the 'NQF' establishment, it will be necessary to check the 'NCS' based on it. On the other hand, there has been no action of the academic world and government. In addition, the subjects related to common occupation capability, skin-related subjects and nail-related subjects are judged to cultivate manpower focusing on the capability, but hygiene-related subjects and basic occupation subjects are judged to seek a new direction to apply as a curriculum for cultivating manpower focusing on capability.
