Thanks to the developments of IT technologies, such critical infrastructures as fundamental structures of energies, material circulations, monetary circulations, and living necessaries are intertwined as well as mutually dependent. In this respect, the fact that national infrastructures are closely related to IT infrastructures implies not only expected benefits to provide diverse information-based services, but also anticipated costs to bring about new dangers. However, in spite of these threats, traditional researchers have not put enough interests in these indirect danger, which yield the damages in broad areas through paralyzing risk management systems, although they have investigated such direct threats as nuclear accidents, conflagrations, traffic troubles, and gasoline accidents. Considering that the tendency to depend on electricity, so-called electrification, which is caused by automation and informationalization, is intensified in all parts of society, the breakout problem as a factor to inhibit securities in information-oriented society is significant. Thus, the problems of large-scale power blackout should be treated as national crises. Also, preparation systems for large-scale power blackout have to be provided quickly. In this paper, with analyzing various cases of large-scale power blackout and investigation the causes of them, researches on the blackout management systems of Korea are to be present, on the basis of national crisis management states which are comprised of protection (mitigating and preparing), responding, and recovering(rewarding).

The regional strategic industry support has been increasingly developed due to the change of environmental and political conditions for the last 10 years. As the paradigm changed from the central government-sponsored system to regional government-sponsored system, the policy has been diversified into various support systems such as regional strategic industry, specialized industry, supporting technology, supporting business, etc. It is crucial to establish the overall development plans and project strategies for the regional industry in terms of effectiveness and efficiency which will generate an integrated strategic frame to adjust overlapped supporting policies and offer a consumer-oriented service. Not only does the study focus on performance-based outcome regarding to a regional business (supporting policy) portfolio, but it also analyzes and proves an empirical decision-making model to draw out the priority and relative importance according to the regional strategic industry and support cases by analyzing the case of Chungnam area's strategic industry support in 2009. Following a priority list of 20 support cases selected from this research model by the Analytic Hierarchy Process (AHP), the result shows that the diverse support plans are needed according to the different strategic industries or the size of enterprise due to the fact that priority of project type varies upon the characteristics of strategic industry. Thus, the support project needs to generate various strategic industries and develop differentiated support policy to consolidate competitiveness of regional enterprises and revitalize the regional economy.

In this paper, we investigate a problem with an e-learning system for e-business environments and introduce the solving method of the problem. To be more accurate, existing Web-hosted and ASP (Application Service Provider)-oriented service model is difficult to cooperate and integrate among the different kinds of systems. So we have produced sharable and reusable learning object, they have extracted a principle from pedagogical designs for units of reuse. We call LIO (Learning Item Object). This modeling makes use of a constructing for XML Web Services. So to speak, units of reuse from pedagogical designs are test tutorial, resource, case example, simulation, problem, test, discovery and discussion and then map introduction, fact, try, quiz, test, link-more, tell-more LIO learning object. These typed LIOs are stored in metadata along with the information for a content location. Each one of LIOs is designed with components and exposed in an interface for XML Web services. These services are module applications, which are used a standard SOAP (Simple Object Access Protocol) and locate any computer over Internet and publish, find and bind to services. This guarantees the interoperation and integration of the different kinds of systems. As a result, the problem of e-learning systems for e-business environments was resolved and then the power of understanding about learning objects based on pedagogical design was increased for learner and instruction designers. And organizations of education hope for particular decreased costs in constructing e-learning systems.

This study examined how historical facts of the past were established as a symbol or identity of a region and reorganized in the present local communities. Janseong has reorganized regional symbols through a regional festival named Hong-gil-dong Festival based on its tradition and cultural resources and used them as a strategy for the regional revitalization. Jangseong was known as "a district of noble scholars" represented by the Philam Seowon(local school) enshrining Kim In-hoo, a superior one of the Confusion scholars of Joseon period. And it was considered as "a place of justice" because of historical fact that it was an important base of Donghak movement and the struggle by righteous soldiers who fought for the country in the late Joseon period. Moreover, as the place which is assumed as a birthplace of Hong Gil-dong, a hero of the Hong Gil-dong story was excavated, the local government has reorganized Mr. Hong as a symbol of the region and has held the Hong Gil-dong festival for its development. In spite of its short history, the festival was established as a representative of Janseong. It also created various regional cultural attractions such as regional logos of Hong Gil-dong and a tourist attraction of his birthplace. Jangseong reorganized its tradition for the regional revitalization through a business-oriented property of the event strategy enforcing a dynamic and external image. In the aspects of tradition reorganization and use for actual development, it is sure that the Hong Gil-dong Festival will work for true integration and revitalization of the region by providing experiences of reorganized regional tradition and culture along with various regional landscapes.

Despite the fact that South Korea, one of peninsula countries, has been already a middle power in an international arena, it still tends to get stuck in continental-driven inertia and be reluctant to become a consolidated maritime power. In its efforts to deal with the parable of South Korea, designing a tailored-made strategy needs to be initiated in detail. Its design is centered around two variables: classification of waters and prestige. First of all, the domain of waters confronted to South Korea ranges from the greatest threat to scattered national interest. Second, South Korea is prestigiously regarded as the middle power which is equipped with the capability to see beyond its sovereign waters. The Maritime Access Strategy(MAS) can be more clearly explained by three-axis factors: ends, ways, and means. Ends need to be oriented to achieving three types of classified objectives-Deterrence, Engagement around the world to maximize remotely-scattered interest and Check of neighboring countries' seapower expansion, called DEC. Ways is mainly driven by the closer access to three different types of waters: waters of security, check, and interest. The active access and closer approach to the domain of waters need to be maintained with a high degree of willingness and capability. Means is attainable by guiding naval forces to be armed with multiple platforms and functionally-balanced assets. These platforms and assets will allow the naval forces to attain and maintain cost effective means, leading to making MAS feasible. This strategy allows the middle-power Korea to make the best of its maritime assets at various seas, contributing to international stability as well as national security and interest.

Although the South Korean organic food market is in the infancy compared to other industrialized countries, Korean consumers'interest in organic food and retail stores devoting space to organic products have been rapidly increasing. Despite the fact of organic food popularity, the term "organic" is interpreted differently by individuals. As opposed to the US, Japan and the EU where have operated an integrated organic food labelling system, Korea has adopted complex organic labelling systems regulated by several different government bodies. As a result, complicated food labelling standards make consumers confused when purchasing organic foods. Furthermore, in terms of country of origin (COO), it is argued by a lot of researchers that COO effects vary from product to product and from country to country; moreover, other informational cues such as brand and price can influence COO effects. In modern society, COO labelling has been complicated, due to the sourcing, manufacturing and market locations of merchandise spread over the world. Accordingly, the evaluation of COO effects has become complex. In order to examine these issues, a quantitative research was selected to classify the commonfeatures of organic food consumers and construct statistics such as the extent to which people are aware of organic food and COO labellingvia a questionnaire which took place in two cities in Korea with a cluster sample of 161 organic food purchasers. As for the data analysis, one-way analysis of variance (ANOVA), T-tests, bivariate crosstatulations with Cramer's V were conducted,depending on the characteristics of variables and the assumptions the research data need to fit. It has been concluded that in general, Korean organic consumers comprehend the term "organic"in a closer way to the general concept rather than technical term, thus people do not appreciate environmentally labels which include organic food labels, although marital status influence the degree of label awareness, regardless of gender, age, education level and so on. Regarding COO effects on organic food, home organic products were Korean consumers'first choice over those from industrialized countries and developing nations. Specifically, in processed organic product category, domestically cultivated and processed organic products were absolutely preferred to leading national brands produced with imported ingredients and international brands. However, due to a lack of checks of ingredients' COO, consumers tend to purchase a leading national organic food brand, believing that it is a pure organic food sourced domestically. As a consequence, this research has suggested some important managerial implications and future research directions. In order to prevent consumer confusion when buying organic foods, it should be noted that consumers do not comprehend the organic food certifications, due to complicated labelling systems for organic produce and processed organic foods. Therefore, government bodies related to organic food distribution have to know consumers' perception of organic food labels and the significance of customer-oriented labels and reestablish labelling standards. Similarly, public advertising should be followed to raise public awareness of the labelling to enable customers to have the correct information. In addition, not only international marketers but also domestic marketers need to understand COO images and also the influence COO of ingredients has on the image of an organic product.

Health care expenditure might be understood as a core source of social welfare. It is mainly due to the fact that the health care expenditure is closely related to the level of social welfare. And, therefore, the paper is basically designed to investigate the effect of social welfare improvement resulted from an increasing in per capita, private, public, and total health care expenditures during 1995-2009 periods. Empirical evidence reveals that the improvement of social welfare in middle income group reveals the highest improvement in social welfare, and the other income groups maintain a quite similar pattern in improvement of social welfare. As far as category of health care expenditure concerns, the effect of social welfare improvement by per capita health care expenditure is in general lower in all case. And, private sector achieves the highest improvement of social welfare in comparing with public and total health care expenditures. To this end, it could be tentatively concluded that the private health care expenditure has to be substituted for the public sector to induce market-oriented operational system. Accordingly, it would be better to build an institutional basis more elaborately in setting up the market system.

Development of Internet technology and the spread of various smart devices provide a convenient computing environment for people, which is becoming common thanks to the Internet of Things (IoT). However, attacks by hackers have caused various problems, such as leaking personal information or violating privacy. In the IoT environment, various smart devices are connected, and network attacks that are used in the PC environment are occurring frequently in the IoT. In fact, security incidents such as conducting DDoS attacks by hacking IP cameras, leaking personal information, and monitoring unspecified numbers of personal files without consent are occurring. Although attacks in the existing Internet environment are PC-oriented, we can now confirm that smart devices such as IP cameras and tablets can be targets of network attacks. Through performance evaluation, the proposed protocol shows 11% more energy efficiency on servers than RSA, eight times greater energy efficiency on clients than Kerberos, and increased efficiency as the number of devices increases. In addition, it is possible to respond to a variety of security threats that might occur against the network. It is expected that efficient operations will be possible if the proposed protocol is applied to the IoT environment.

The purpose of this study is to make a plan for the development of new tour routes for '98 Kyongju World Culture Exposition. The result of this study is as follow: First, over 40% of tourists from Kyongsang-buk-do Province vote for Kyongju Area as the most favorite tourist-oriented city in this province. And they are visiting Kyongju mostly in April(22.6%) and in May(17.8%). Second, cultural assets in Kyongju area are located at Inkyo-dong(16.8%), at Bohwang-dong(9.4%), at Topjong-dong(8.1%). at Mt. Namsan area(11.8%, 6.9% for Naenammyon, and 4.9% for Dodong-dong), and at the vicinity of Kyongju City(53.9%). Third, tourism enterprises in Kyongju Area are located mostly at one place-Pomun Lake Resort area. This fact have had bad influence on the influx of tourists. Lastly, current tour routes are limited mostly to the heart of Kyongju City. So, other attractive tour routes must be developed also in other tourism circles such as the East Sea Tourism Circle and the Northern Province Tourism Circle, which belong to the 6 tourism circles designated by Kyongju City but are now excluded from the current tour routes. In conclusion, this study proposes "98 Kyongju World Culture Exposition with Themes" related to the 6 tourism circles. The themes proposed are as follows: (1) The exploration of the historical places of the Shill a Kingdom in the heart of Kyongju City including Mt. Seoak area and Pulkuksa Temple area. (2) Smile with a new millenium in Pomun Lake Resort area. (3) The exploration of the Buddhist culture in Mt. Namsan. (4) The harmony between nature and culture in the East Sea Tourism Circle and the Northern Culture Circle.
