The purpose of this paper is to describe the Disaster Management System Development of Enterprise GIS at the Kangwon Province in Korea. This project is included into 'the Kangwon Enterprise GIS 21 plan'. The Division of Disaster Management is in the middle of the 2-year project of the Disaster Management System development, appropriate for business performed at the Departments of Forestry, Culture, Environment, Tourism, etc. At the 1st phase of CIS implementation, for more than half a year we focused on the necessity of management of disasters. In the planning process, we needed long-term information on the whole area of Kangwon. In the assessment and response processes, we needed real-time data from Korean Meteorological Administration and other agencies. All the above information was carefully studied and referred to. ESRI's new GIS technologies solve the natural hazard/disaster problems. For example, hazardous materials routing often needs to be found the least expensive path through a roadway network. In the circumstances given, we can choose the departure point and destination of the vehicle, which carries the materials. It's also possible to minimize overall risk and costs of disaster problems by making a plan of people and possessions evacuation from the disaster area in short time limits. We can meet all the above goals using the latest ESRI's technologies.

A conventional elastic material replacement and performance evaluation are very complicated and time-consuming, and it is difficult to know when to replace the elastic material in advance. By comparing with the product limit and the functional limit, the necessity of elastic material replacement and the improvement of track support stiffness according to replacement can be immediately demonstrated based on experimental data. Using an evaluation system of track support stiffness, the performance evaluation data for elastic materials obtained through field tests using software for track support stiffness is integrated and managed on the administrator's computer. Therefore, the replacement plan is established and maintenance history is managed by identifying the replacement time and location of elastic materials. It is possible to evaluate the performance and condition of the elastic material at the various points during the working time of the track inspection and the track performance (track support stiffness) and durability of the elastic material (aging level, spring stiffness variation rate, etc.) at the operation condition. The elastic material could be replaced timely, and the deterioration of the elastic material can be continuously monitored.

This study compared the college students' dietary behavior for processed foods, who will be the main consumers in the future and looked for the measures to understand and establish the right food labeling system by surveying the level of understanding and utilization of food labeling. The data was analysed by SPSS win 17.0 program, and the results are as follows. For the standard of selecting processed foods, the group with high nutrition knowledge considered the reliability of foods as important and the group with low nutrition knowledge considered the products introduced in TV commercial as important. When purchasing processed foods, the group with high nutrition knowledge considered nutrition, taste, price, appearance(shape), and the consumable period more than the group with low nutrition knowledge. For trans fat, the group with high nutrition knowledge learned more about it than the group with low nutrition knowledge. The ratio of confirming food nutrition label was higher in the group with high nutrition knowledge. Regarding the level of confirming individual food labels, the highest level was for milk and dairy products. And there was significant difference for the processed products of meat, cookies, bread and noodles. It was found that the level of confirmation was higher in the group with high nutrition knowledge. And the most important indication for individual food product was the consumable period. To preserve the purchased foods, the group with high nutrition knowledge preserve the foods in line with the description written on the food cover sheet, and this group used to return or exchange the products when they found them spoiled or purchased by mistake. The group with high nutrition knowledge knew more about the nutrition indication than the group with low nutrition knowledge. The necessity of nutrition indication for processed foods and the need of education and PR(Public Relation) were acknowledged higher in the group with high nutrition knowledge. For the effect of nutrition indication, it showed that the group with high nutrition knowledge thought it would improve the quality and the group with low nutrition knowledge thought it would be helpful when comparing the product with others. The group with high nutrition knowledge showed higher understanding level about nutrition indication than the group with low nutrition knowledge.

Recently, learning how to learn is a matter of concern among many pedagogists and become the important subject matter of school education. That's why there are many learners who fail to get good results compared with their potential abilities and efforts, as well as the necessity to educate independent and self-determined learner by teaching learning strategies that can help leaners to get new information and skills by themselves in an information-oriented society was emphasized. Therefore, this study is to utilize the learning strategy in order to improve the learners study skills, and grope for the method of self-directed learning about the social studies centered on the learners. And, it is to utilize the reciprocal teaching with the learning strategy for improving the learners study skills. Also, it is to make the learners induced to participate in the teaching for social studies actively, grafting the characteristics of web on the reciprocal teaching. According to this intent, this study was developed as three steps. As for the first step, it investigated the reciprocal teaching, a teaching-learning theory to apply to the program, and the theoretical background about web utility in the social studies. On the second step, it embodied the reciprocal teaching-learning system about the we-based social studies that will be available in the self-directed learning centered on the learners. Lastly, it analysed the change of recognition about the learners social study skills and the learning the social studies after applying the materialized website to the actual lesson.

The digital economy has created a new platform-based business model and raised the issue of the international taxation system in line with rapid economic development. Voices of fair taxation have also grown due to tax breaks to countries with low tax rates, problems caused by the gap between traditional and digital companies, and problems of business-oriented taxation systems. As a result, the international movement to lay the foundation for the international taxation system based on the business model suitable for the digital economy has become active. The stances of foreign organizations and countries are different, and the necessity of domestic policy introduction is increasing when cooperation at the international level is needed. This study was conducted to analyze the policy network and to help decision making. The results of the study showed that there were differences among domestic stakeholders depending on the actors. The EU suggested SDP in the long term, Digital Service Tax in the short term, and OECD suggested SEP in the long term. It was found that a careful approach to decision making and an in-depth study of the policy process are necessary.

The present study attempts to provide basic directions to respond to sea-level rise effectively based on the status of sea-level rise and its impact. The impact of the sea-level rise will be one of the most adverse component among climate change due to global warming. The basic approach to deal with sea level rise requires both mitigation and adaptation. Though the emission reduction can reduce a portion of sea level rise, the rising trend cannot be avoided due to the difficulty of the emission reduction and a strong inertia of the ocean. Therefore an effective corresponding direction has to focus on the development of appropriate adaptation strategies. Because sea level rise problem has scientific uncertainty, the corresponding system has to be designed to deal with the processes of information and awareness, planning and design, implementation, and monitoring and evaluation in continuous and long-term process. The future task to correspond effectively to the issue in Korea includes the improvement of scientific information, the development of adaptative measures, the enhancement of people awareness, the consensus of corresponding necessity, and formation of integrated corresponding system.

The state has the constitutional duty to secure the safety of its citizens and provide protection against any physical dangers. The Republic of Korea has a high threat of nuclear, biological and or chemical(hereafter referred to as NBC) attack from the Democratic People's Republic of Korea. Thus, the state has a responsibility to form a legislation to provide the protection for its citizens and implement duty to guarantee the human rights. Under the current legislation, the 'United Defense Act', 'Framework Act on Civil Defense' that are applied under wartime conditions are insufficient in providing the protection of the citizens of the state in the occurrence of NBC attack. Therefore, it is necessary that the 'Act for the Protection of Citizens in the occurrence of NBC Attack' is legislated to provide a system that protects the nation's citizens under the wartime conditions mentioned above. This paper incorporates a theoretical analysis of the need for the constitutional responsibility of the state to provide protection for its citizens under wartime conditions, the necessity of a specific measure to protect citizens during NBC attack, the relationship between 'Act for the Protection of Citizens in the occurrence of Nuclear, Chemical and or Biological Attack' and current legislations that are applied under wartime conditions, and the particulars of the proposed act.

This study assesses the necessity of popular music instructor training, and promotes the establishment of popular music educational institutions and certification related to applied music education. Popular music has profound influence in popular culture, and is gradually diversifying. However, successful singers predominantly remain mostly boy/girl performance groups lacking musical skills. This study posits the cause of this problem is the absence of popular music instructor training systems, and suggests solutions. Currently, Korea's popular music lacks a public education system that teaches students effectively. Also, popular music is acknowledged as field-oriented, and isn't recognized for its academic value. Lastly, the lack of professional instructor training system in higher educational institutions creates challenges in fostering effective teachers. Solutions to these problems include establishing dedicated educational institutions and establishing certification programs. Implementing these solutions will provide significant positive effects in developing globalization for the currently stagnant K-pop industry. In addition, these solutions would contribute to the stabilization of the popular music industry, enhancing the image, and developing the popular music industry in general. In conclusion, this study promotes the popular music industry development by influencing and promoting awareness of music professionals, not just applied music students.

An electronic cash system has to provide the security, to prevent the double spending and to support the divisibility of electronic cash for the easy of use. Divisible electronic cash system allows an electronic cash to be divided into subdivisions. Each subdivision is worth any desired value, but all values must add up to the original cash value. Divisible scheme brings some advantages. It reduces to make the change and also there is no necessity that a customer must withdraw a cash of the desired value whenever transactions occur. In this paper, we present an electronic cash protocol which provides the divisibility based on the double hash chain technique. Electronic cash is constructed in the form of coins. Coins, generated by the double hush chain, have different denominations. The divisibility based on the double hash chain technique. Electronic cash is constructed in the form of coins. Coins, generated by the double hash chain, have different denominations. The divisibility of an electronic cash is satisfied by the payment certificate, which is a pair of bank´s proxy signature received from the bank. When a customer pays the coin of subdivision, the fairness of that coin is certified by a customer´s signing instead of a bank. Although the proposed method does not guarantee user´s anonymity, it generates coins which cannot be forged, and the customer can use an electronic cash conveniently and efficiently with its divisibility.
