This study aims at deriving any useful information necessary to strengthen the competitiveness for growth through empirical analyses on general hospital located in a province in order to countermeasure the opening and competition of medical markets. The characteristics of user were identified on the basis of disease groups under KCD in the research method. In addition, the analysis on the expenses of diagnosis and treatment was divided into the treatment progress and degree of hospital resource utilization And the regression was carried out to identify the impacts of characteristics of inpatient users on the degree of hospital resource utilization. As a result of major research, the inpatient users of the general hospital located in the provincial area in consideration of inpatient users were formed around the inpatient disease groups representative for Korea(diseases of the respiratory system, injury and poisoning & certain other consequences of external causes). And it was understood that most of residents within a distance of 40 minute by the public transportation were using. And mostly were under the age of 9 or over 60, and the provision of medical features such as the degree of consultation and operational functions were inadequate. When we classify inpatient treatment cost for each resource application as the medical cost being the center of patient care function, the equipment and human resource application sector are constituted over half. Accordingly, the following suggestions are made as plans to strengthen the competitiveness for the growth of general hospitals located in the provincial areas on the basis of analytical results. First, it is necessary to have the characterization matching to the age and disease groups with a high frequency. Second, it is necessary to increase the degree of hospital resource utilization according to the characterization. Third, it is necessary to concentrate on public relations. The above suggestion, as a method for securing image improvement and competitive power as a general hospital, and through expansion of social function that a regional general hospital needs to secure not only as an individual institution but also as a general hospital, it can be seen that a general improvement of image as a regional general hospital is possible.

Economic security emerged as a strong element of national security. Nations around the world are exerting their efforts to collect economic intelligence to serve their national interest while making added efforts to uncover industrial espionage and arrest industrial spies in defensive aspect. Cases in point are the enactment of "Economic Espionage Act(1996)" of the U.S. and the "Act on Prevention of Divulgence and Protection of Industrial Technology(2006)"of Korea. Korea is trying to punish industrial spying on the same level as espionage that poses national security threat by revising Criminal Code. It is necessary to review whether the move to toughen the punishment of industrial spying from "up to 15 years in prison and/or up to 1.5 billion won in fine" to "minimum seven years of imprisonment, life imprisonment or death penalty" is appropriate. Advanced nations regulate industrial spying with a special act on economy although they have applied espionage act not to "enemy states" but to "foreign countries" in the first place. Likewise, preventing industrial spying by applying espionage act through the revision of criminal code poses a risk of undermining the autonomy of industry sector by excessive influence of state power. Furthermore, the penalty of minimum imprisonment of seven years, life imprisonment or death penalty with the application of espionage act under the criminal code is an legal application by stretching of the law, posing a risk of dampening healthy economic activities. Therefore, revising and applying relevant economic laws such as aforementioned 'Act on Prevention of Divulgence and Protection of Industrial Technology(2006)' is thought to be desirable to achieve the goal of protecting industrial technologies.

Mt. Baekdu, Mt. Aso, Mt. Sakurajima, Mt. Kikai and etc are distributed around the Korean Peninsula. Recently signs of eruption of Mt. Baekdu are increasing, raising concerns over possible damage to volcanic ash from seasonal winds during the winter eruption. Therefore, detailed procedures for investigation and countermeasures for volcanic ash spread and damage are required. But the standards for the warning and alarm signal of volcanic ash presented by Korea Ministry of Government Legislation are vague, with "when damage is expected" and "when serious damage is expected". In this study, to analyze the damage threshold and to apply the cases of overseas damage to the country, a survey was conducted on the establishment of domestic spatial information by public institutions with public confidence. As a result of the investigation of damage from volcanic ash overseas, the details of the damage cases were different depending on the type of life or income sources of each country. Therefore, instead of applying the volcanic ash damage cases abroad in Korea, spatial information analysis was performed to reflect domestic social and natural characteristics. In addition, we selected the areas to be considered in the event of volcanic ash damage in Korea. Finally, domestic volcanic ash damages should be classified as health, residential, road, railroad, aviation, power, water, agriculture, livestock, forest, and soil. When establishing the volcanic ash alarm optimized for Korea in the future, overseas volcanic ash damage cases and domestic spatial information construction in this study will be helpful in policy establishment.

As Japanese economy has been well developed, the manpower problem of farmland has also become one of the largest and the most crucial issues in the overall agricultural policy of the Japanese Government. Particularly, the energetic younger generation and a core of agricultural labor force, has drastically decreased, while the weak older generation has increased. The severity of manpower shortage in agricultural sector led to create a farmer training programs which had been vigorously begun by the Yamagata Prefecture, and a center for promoting local autonomy. The major purpose of education for enhancement of status of future farmers as well as the welfare of core farmhousehold is to provide them with technical of vocational education to give training to those who want to become agricultural technicians, rural leaders of practical farmers Educational program for future and young farmers put emphasis on practical trainings which are directly applied to proper farm management. As a supporting policy for promoting future farmers' activities, Prefecture-level supports were strengthened to develop technical capability, managerial and supervisory ability, and the ability to lead organized activity so that the farm youth may operate modern farms with higher efficiency and greater specialization. Political consideration was also made to develop a rich sense of farm management as well as the adaptability necessary to introduce technical and managerial innovations. Methological measurements on how the Korean government has to do for solving the problem of agricultural manpower facing in farmland in Korea were noted.

The purpose of this study is to trace the path of policy for urban parks and greenbelts (PUPG) pursued by Seoul Mayor Kim Hyeon-ok, who was a protagonist of Seoul's modernization and to reveal the policy's characteristics. A high modernism perspective was projected to advance his PUPG discussion. High modernism was an unavoidable phenomenon that appeared in post-war urban reconstruction projects and emerged in the form of a belief that the national elite creates the ideal social order and rational planning. Its characteristics were to build with legibility, immediacy, and convenience by power, with private participation and profit creation, while realizing the spectacle of "the city being built". As a high-modernist, Seoul Mayor Kim Hyun-ok's urban planning aimed to deal with the booming population and the expansion of Seoul's territory. Although his PUPG extended the parks to the outskirts of Seoul, he showed a dualistic attitude, diverting parks away from the city center. On the other hand, he induced the participation of the private sector to create parks. However, he showed the other side of modernization, eliminating the placeness and excluding related systems. The path taken by Mayor Kim Hyun-ok's PUPG was started to respond to population growth and resolve the encroachment of parks. The ultimate goal was to accept the realization of urban planning and experiment with non-financial methods. The characteristics of his PUPG reflecting high modernism were: First, elites were represented in the National Land Planning Association, HURPI, and Jang Moon-gi participated; second, legibility was ensured by using east-west and north-south axes, elevation standards, and rational planning. Third, parks were quickly released to respond to the rapid urban change. Fourth, it showed off events and spectacles to attract private capital.

LED light has various advantages such as an energy saving effect of over 80% compared to existing lighting and environmentally friendly characteristics; however, there has been no affordable market for LED lighting because of its expensive price. This study discussed the validity of the expansion of distribution of LED lighting through an assessment of economic efficiency concerning LED lightening in order to analyze its efficiency in terms of energy savings and maintenance and repair, which will be generated as a result of the change from existing incandescent bulbs to LED lighting in the public sector. As to the target of analysis, the paper reviewed the validity of change to LED lighting as a result of the elimination of existing incandescent bulbs, by referring to 'the current incandescent bulb use and elimination performance' published by the Ministry of Knowledge Economy based on the "Elimination management system" executed by Korea Energy Management Corporation. The paper considered expenses for change, annual power savings amount and electric charges savings amount, repair and maintenance cost, $CO_2$ reduction volume, and the profit from the sale of CER (certified emission reduction). As a result of analyzing economic efficiency, when the discount rate during the change of existing incandescent bulb lighting to LED lighting is 3.26%, the profit was 8,648,400,000 won. Accordingly, NPV was analyzed to have a 'positive (+)' value, which means that this change is profitable.

Low-Orbit satellite mobile networks can provide services through miniaturized terminals with low transmission power, which can be used as reliable means of communication in the national public disaster network and defense sector. However, the high traffic environment in the emergency preparedness situation increases the new call blocking probability and the handover failure probability of the satellite network, and the increase of the handover failure probability affects the QoS because low orbit satellites move in orbit at a very high speed. Among the channel allocation methods of satellite communication, the FCA shows relatively better performance in a high traffic environment than DCA and is suitable for emergency preparedness situations, but in order to optimize QoS when traffic increases, the new call blocking and the handover failure must be minimized. In this paper, we propose LEO-DBC (LEO satellite dynamic beam width control) technique, which improves QoS by adaptive adjustment of beam width of low-orbit satellites and call time of terminals by improving FCA-QH method. Through the LEO-DBC technique, it is expected that the QoS of the mobile satellite communication network can be optimally maintained in high traffic environments in emergency preparedness situations.

Electrochemical carbon dioxide (CO₂) reduction technology, one of the promising solutions for climate change, can convert CO₂, a representative greenhouse gas (GHG), into valuable base chemicals using electric energy. In particular, carbon monoxide (CO), among various candidate products, is attracting much attention from both academia and industry because of its high Faraday efficiency, promising economic feasibility, and relatively large market size. Although numerous previous studies have recently analyzed the GHG reduction potential of this technology, the assumptions made and inventory data used are neither consistent nor transparent. In this study, a comparative life cycle assessment was carried out to analyze the potential for reducing GHG emissions in the electrochemical CO production process in a more transparent way. By defining three different system boundaries, the global warming impact was compared with that of a fossil fuel-based CO production process. The results confirmed that the emission factor of electric energy supplied to CO₂-electrolyzers should be much lower than that of the current national power generation sector in order to mitigate GHG emissions by replacing conventional CO production with electrochemical CO production. Also, it is important to disclose transparently inventory data of the conventional CO production process for a more reliable analysis of GHG reduction potential.

Natural gas consumption in Asia is growing at fast tempo because of various factors such as economic growth in the region, urbanization, coal-to-gas switch at power and industry sector. Due to geographical characteristics and lack of international pipeline connections between countries in the continent, majority of natural gas exported to Asian consumers is transported by tankers on the sea in the form of liquefied natural gas. As Asian market is the most lucrative market with the fastest demand growth, the competitions between LNG sellers for market share in Asian market are strengthening. The competitions accelerated, especially after the introduction of large volume of incremental supply into the market by new exporters from the U.S., Australia, and Russia. Cheniere Energy, the first exporter of liquefied natural gas (LNG) in the lower 48 states of U.S. has not adopted the traditional price formation mechanism and business model. Traditionally, prices of long-term LNG contracts have been indexed to the price of competing fuels, such as crude oil. The company adopted a pricing mechanism and business model based on a cost-plus system. Cheniere Energy opted for the safer and the risk-free pricing system, that annually guarantees a fixed amount of revenue to the seller. The company earns the same amount of money, regardless of natural gas price dynamics in the domestic and international market, but possibly with less revenue. However, by introducing and successfully implementing the safer and risk- free business model, Cheniere Energy, a company of a relatively smaller size in comparison with major oil and gas companies, became an example to other smaller-sized companies in the U.S. The company's business model demonstrated how to enter and operate LNG business amid increasing competitions among sellers in the U.S. and international market.

This paper examines middle powers' ODA policy in the post cold war era and discusses its implication for Korean aid strategy. Middle powers' ODA has been more successful than that of super powers in promoting donors' positive images and in stimulating recipient countries' development. Middle powers tend to pursue multilateral solutions to international problems often by taking a mediator role, and their ODA policies set them apart from the great players in international politics. Middle powers' ODA is primarily aimed at reducing poverty and protecting human rights in least developed countries where humanitarian aid needs the most rather than promoting donors' interests. Also, middle powers have provided bilateral untied aid in the sectors of food aid and emergency relief and steadily devoted about 0.7% of their gross national income to ODA. Meanwhile, Korea as an emerging middle power and a new donor has been implementing its own aid strategy under the name of the Korean development model since the post cold war period. The Korean ODA was not successful in building donors' positive images by simply following the short term strategies of US and Japan. Yet, its ODA policy has been quite effective in sustaining local development by creating specific niches in which the country can specialize in. In specific, Korea has focused on developing the sectors of information and communication technology and industry energy in recipients' countries by maximizing its comparative advantage.
