Korea successfully achieved energy independence in the shortest period of time from being the poorest country in terms of energy 50 years ago through steady development of nuclear technology. In the past, the nuclear industry has been driven through government-centered policy development, public institution-based research, and industrial facility and infrastructure construction. Consequently, South Korea became a nuclear energy powerhouse exporting nuclear power plants to the UAE, surpassing the level of domestic technological independence. However, in recent years, the nuclear industry in Korea has experienced a decline in new plant construction since the Fukushima accident in Japan, which caused changes in public perspectives regarding nuclear power plant operation, more stringent safety standards on the operation of nuclear power plants, and a shift in governmental energy policy. These changes are expected to change the domestic nuclear industry ecosystem. Therefore, in this study, we investigate the priority of technology development investment from the perspective of experts in private nuclear power companies, shifting the focus from government-led nuclear R&D policies. To establish a direction in nuclear technology development, a survey was conducted by applying an analytic hierarchy analysis to experts who have worked in nuclear power plants for more than 15 years. The analysis items of focus were the 3 attributes of strategic importance, urgency, and business feasibility of four major fields related to nuclear energy: nuclear safety, decommissioning, radioactive waste management, and strengthening industrial competitiveness.

This study was conducted to investigate priority recognition of experts and related facility operators in establishing policies for revitalizing agro-healing services. After reviewing related studies, 5 policy division and 19 detailed sector were drawn, including improving accessibility, improving promotion and information provision method, improved public relations and information provision, diversification of facility and program, financial support, and expansion of expert and specialized institutions. A questionnaire survey was conducted on agro-healing experts, agro-healing facility operators, social welfare experts, and social welfare facility operators. The AHP analysis indicated that agro-healing experts and facility operators had the highest priority in the division of expansion of expert and specialized institutions, while social welfare experts and facility operators had the highest priority in financial support. The IPA analysis was conducted to identify the priority of each policy sector. Respondents recognized above normal importance to policy divisions, but were relatively aware of the importance of improving accessibility, with overall satisfaction level appearing to be moderate. The results of this study are expected to provide useful information for establishing agro-healing policies and for establishing effective strategies.

This study investigates the barriers to the deployment of solar thermal and ground source heat pump (GSHP) from the perspective of consumers and businesses, as well as evaluates priorities for improving the barriers via expert AHP evaluation. From a consumer's perspective, the overall satisfaction with solar thermal is significantly lower than that with PV and needs to be improved at the installation and use stages. GSHP needs to be improved at the prior-information search stage. From a business perspective, the non-distinction between heat and electricity in mandatory installations in public buildings, the difficulty in assessing the value of heat, and high initial costs impede the deployment. Based on the result of AHP analysis, the priorities for improving the barriers to the wide utilization of solar thermal are evaluated in the order of economic feasibility, policy, acceptability, and technology, where high installation cost is shown to be the greatest barrier. Barriers for GSHP are evaluated in the order of policy, acceptability, economic feasibility, and technology, where policy means improvement is evaluated as the most important factor in promoting the deployment of GSHP.

Since the great acceleration, the emergence of the sustainable development concept amid the conflict between economic growth and the preservation of the natural environment is at a time when an efficient land-environmental plan integration system is needed to achieve a smart balance between development and conservation. Although preceding studies have been conducted domestically and internationally on various aspects, the operating system has not been implemented effectively. In this study, the policy concept of environmental policy integration, the current status of integrated management of land-environmental plans in South Korea, and related literature studies were reviewed to derive overall complementary points. In addition, the review was carried out by reorganizing the domestic urban planning legal-based system and the environmental legal-based system according to the same hierarchy to promote an effective integration system, and in foreign cases, the establishment of spatial and environmental plans in Germany and Japan was typically considered to derive implications for the establishment of an efficient interconnection system for the integrated management of domestic land-environmental plans in the future.

Big science such as nuclear fusion accelerators shares the characteristic of requiring long-term and massive budget input, human power, and related state-of-the-art technology. Because big science, by nature, thus requires large-scale budgets and facilities yet harbors the possibility of failure, most projects are led by the government. When the actual circumstances are examined, however, such projects are often implemented through the formation of cooperative relations with small and medium businesses (SMBs) possessing outstanding technological capacity. On the other hand, the reality is that the entry of corporations into the business ecosystem of big science is not easy and that even those that have once entered big science likewise fail to find sales outlets for technology that they have developed following the supply of single items, thus leading their technological capacity to lie idle. Consequently, based on an awareness of the problem, the present study seeks to propose strategies for activating the business ecosystem of nuclear fusion and accelerators and to present alternatives regarding which policy tasks must be pursued first by using the analytic hierarchy process (AHP) technique. The present study derived the four policy alternatives of approach, care, expansion, and infrastructures in accordance with the results of empirical analysis to activate the business ecosystem of nuclear fusion and accelerators and analyzed their priority in terms of urgency and effectiveness, the results of which were, in this order: care-approach-expansion-infrastructures. The significance of such research results lie in presenting the policy direction when the government determines which policy task must be pursued first and implements strategies for the activation of the business ecosystem of nuclear fusion and accelerators with limited financial resources in the future.

Structural flood defensive alternatives have been evaluated based on economic feasibility, riskiness of safety and sustainability. Social problems associated with structural flood defensive alternatives such as dams, flood control channels, etc. are currently issued. The evaluation items of policy presented in KDI(2001) are should be modified in order to resolve the social problems. Hence, this study conducted a questionnaire survey of public servants, researchers, and engineers to obtain how to determine evaluation items for policy assessment and to compute their weights in the analytic hierarchy process. This study also compared the weights of the items in KDI(2000) with the weights from the survey in this study. The policy assessment weight was estimated higher than KDI(2000). This result suggests that social awareness increases and the analysis of policy becomes important for selecting optimal structural defensive alternatives.

This study analyzed the globalization policy of ICT SMEs and ventures using cognitive map analysis and derived the priority to importance about action plans using AHP model, while the globalization paradigm has been rapidly changing in the ICT industry. Empirical results showed that policy tool variables should be needed to develop because policy goal variables are generally presented more than policy tool variables. In addition, this cognitive map could be characterized by a scarcity of feedback loops which means policy landscape for ICT SMEs and ventures' globalization is unilateral rather than cyclical to reach policy goal from policy tools. Another finding is that creative economy policy variable was not observed as policy tool variable but as policy goal variable. This means creative economy can be implemented through support for ICT SMEs and ventures' globalization. Finally, for detailed policy measures, installation of global start-up center, recruiting and utilization of global specialists, revitalization of ICT R&D international collaboration study, enlargement of global investment network, accompanied overseas advance of large enterprises and SMEs are presented in order in terms of the importance of policy priority.

Health care has two different facets. One is commodity and another is a right of human being. Health care as a commodity is utilized by demand approach in market. Demand is determined by economic factors such as price and income. From the last third of the 19th century until the early 1920s, priority of sickness insurance was replacing the income that workers lost as a result of illness and injury. By the 1920s, the capacity of applied biological and medical science was remarkably developed. Development of medical science stimulated the cost of medical care, and the burden of increased medical care cost required new role of medical care security system. In 1942, Beveridge report was published in United Kingdom, and health care was considered as a right of human being. In 1948, United Nations declared heath care as a right in the Universal Declaration of Human Right. In most countries introduced new medical care security policy based on health care as a right. The viewing health care as a commodity must be shifted toward need based care as a right. Need were understood to rest on demographic, epidemiological, scientific, and medical knowledge factors. Bring needed care to the population could best be achieved institutionally by a hierarchy of provider organizations, guided by planning bodies, which would provide comprehensive benefits. In Korea, health care in social health insurance (SHI) is considered as a commodity not a right. However, health policies under SHI must be need approach based on health care as a right. Mismatch between health policies and ideology of SHI made big troubles. It is important to realize ideology of SHI for good health policies.

An important characteristic of role-based access control model(RBAC) is that by itself it is policy neutral. This means RBAC articulates security policy without embodying particular security policy. Because of this reason, there are several researches to configure RBAC to enforce traditional mandatory access control(MAC) policy and discretionary access control(DAC) policy. Specifically, to simulate MAC using RBAC several researches configure a few RBAC components(user, role, role-hierarchy, user-role assignment and session) for keeping no-read-up rule and no-write-down rule ensuring one-direction information flow from low security level to high security level. We show these researches does not ensure confidentiality. In addition, we show the fact that these researches overlook violation of integrity due to some constraints of keeping confidentiality. In this paper we propose a RBAC model satisfying both confidentiality and integrity. We reexamine a few RBAC components and constructs additional constraints.

UN, OECD, ITU and other international organizations regularly announce ISI (Information Society Index) to utilize in establishing and evaluating information policies. ISI is utilized as important data for countries to evaluate their information policy performance and select future projects. As the advancement of information systems, the importance of information security has been emerged. Accordingly, NISI (National Information Security Index) has been required. NISI number is the most clearly figure to express the characteristics of a particular group's information security. It can be utilized in determining information security policies. Currently, questionnaire method has been used to calculate NISI number. But there is an absolute lack of statistical data, and the reliability of surveyed statistical data is problematic. The objective of this paper is to show how to collect precise micro data of each company's information security index numbers, and to develop an OLAP database system which calculating NISI numbers by using those micro data. In this process of the survey, we presented the technique to collect the data more systematically, and to analyze the data without using questionnaire method. OLAP architecture performs only well on the facts that are summarizable along each dimension, where all hierarchy schemas are distributive. Therefore we transformed the non-distributive hierarchy schema into the distributive hierarchy schema to implement OLAP database system. It is thought that this approach will be useful one from an implementation and schema design point of view.
