The purpose of this study was to confirm that the formation and influencing factors of ocean governance in Busan. Recently it has been observed that the concept of ocean governance increasingly popular in the field of maritime administration, as the concept helps us understand more comprehensively the new or emerging roles of the government and other stakeholders(private enterprise, citizen, etc) in a rapidly changing environments. Therefore, this study aims to investigate the status of ocean governance and draw alternatives in applying appropriate ocean governance structure of maritime administration in Busan. The result of this study shows that ocean governance level in Busan was not high in some factors such as participation, cooperation, collective decision making. This is caused by the lack of a ocean governance structure. Based on these significant research findings, theoretical and practical implications were discussed.

In Korea, telemedicine is still under the beginning stage, but we expect that the developing 'Information Highway' will make this technology more common place and more easily used in coming soon. Currently, three hospitals are providing telemedicine services with their subsidiary hospitals which are far away from their remote place. However, the fee schedule of telemedicine services are not well-settled down, of course not reimbursed through current health insurance system. This study aims to develop new payment system for medical services provided through telemedicaine system. To design appropriate fee schedule for telemedicine services, we, first, review the current insurance payment system and telemedicine system both in domestic and foreign countries focusing on its payment system. A framework of telemedicine payment system is proposed in following steps based on information we acquired from this stage. Second. We decide the span of cost items which should be covered by telemedicine payment scheme. In hear, we suggest payment method for telemedicine services should be designed as dual structure which are telemedicine fee that should be reimbursed through payment scheme and any costs related to capital investment that should not be covered by payment system. Which is, payment system for telemedicine services should cover only service-related costs and any costs related to capital investment should be generated through third party such as government, health insurance association, etc. Finally, we suggest new fee schedules for telemedicine services. The key issues on developing telemedicine fee schedules are related with the determination of appropriate additional rate($\alpha$). The reasonable additional rate($\alpha$) must determine through careful evaluation of any additional efforts(e. g. : additional work hours which are related to providing telemedicine services). This study shows the process of how to determine appropriate additional rate($\alpha$).

According as zone of life of big city is expanded by new city development etc.., need special skill master plan compensation which can be systematic for wide area traffic problem solution and confusion expense minimization in the metropolitan area because wide area of capital region traffic is gone continuously and continues. Accordingly, Kyonggi Province suggested rapid-transit railway achievement that can connect Seoul Gangnam in 20 minutes with Dongtan new city recently. MLTM(Ministry of Land Transport and Maritime Affaris) announced "Capital region railway network improvement plan research services (2007.12)" result that Gangnam High-speed railway route (Suse $\sim$ Dongtan $\sim$ Pyeongtaek) construction for offer High-speed railway service to capital region and Kyonggi southern part area inhabitantses and need to line capacity tribe solution by Seoul-Busan high-speed railway second-stage and Honam high speed railroad completion. Is judged that need examination about wide area rapid-transit railway combined application operation that take advantage of rail track reserve capacity of High-speed railway for utilization efficiency elevation of country and efficient investment of national finance according as High-speed railway and Gangnam rapid-transit railway route that is suggested in Kyonggi Province are overlaped. Therefore, in this research, I wish to quote investment efficiency plan of railroad business by that different kind's train is run in uniformity track by presenting combined application operation plan and working expenses curtailment effect etc. that is optimized through analysis of roadbed and E & M technology condition, intermediate station plan, train operation planning etc. in case of wide area rapid-transit railway and high-speed railway run combined application.

The purpose of this study is to empirically address the influences of motives for using SNS on relational bridging and relational bonding in SNS and motives for continuous use SNS by applying the concepts of bonding and bridging, defined in the social capital theory, and major motives for using SNS are classified into three categories-social, information, and recreation categories - based on the previous studies and the usage and gratification theories. Through this study, it was revealed that motives of all these three categories-social, information, and recreation categories-have significant influences over relational bridging and relational bonding in SNS while relational bridging and relational bonding in SNS have significant influences over consistent motives for using SNS so the hypothesis of this study is accepted. It was also proven that motives of all these three categories - social, information, and recreation categories-for using SNS are important factors for creating new communities or expand relationships with other SNS users sharing similar interests. In addition, it was found that SNS users constantly use SNS to build relationships that could create a strong bond between individuals and receive emotional supports when necessary and to expand its own network by creating new relationships with other SNS users.

In this paper is two-step trade model introduced. It is assumed that countries have 3 basic factors- capital(K), land (Z)and population(N)-as national factor endowments. As the first step, education 'produces' 'educated labor(EL)' which embodies new knowledge or new technology by using the population and capital as inputs. As the second step, manufacturing goods is produced with EL and uneducated labor(UL), and agriculture goods with land and UL. According to this model, the higher the increase rate of capital in a country is, the lower the usage rate of land is, the lower the increase rate of discount is, the country tends to export the manufacturing goods and import the agriculture goods. Trade widens the discrepancy of increase rate of EL in both countries but reduces the gap of increase rate of relative wage of EL as far as the gap of usage rate is not so big. Trade also affect real income rather than nominal income. This model can be extended to explain the migration from rural areas to urban areas when the manufacturing sector and education organization exist in urban area while the agricultural sector exist in rural area.

According to the system dynamics model of this study, if there is a significant network effect on vehicle operating costs, it is difficult to achieve the shift to AFV even in the long term without a policy intervention because the car market is locked in to the current structure. Network effect can be caused by an increasing return to scale in fuel supply sector as well as in maintenance service sector. It is also related to the fact that the reliability and awareness of consumers on new products increases with the growth of the market share of the new products. There are several possible policy options to break the 'locked in' structure of car market, such as subsidy on vehicle price (capital cost), subsidy on fuel (operating cost) and niche management policy. Combined policy options would be more effective than relying on a single policy option to increase the market share of AFV.

This paper analyses the economics of grid-connected photovoltaic systems. With the 2003 cost of photovoltaic systems, under prevailing capital market conditions, with a system lifetime of 30 years, and under the best climatic conditions, it appears that the cost of production of grid-connected electricity could be of 0.21 US $/kWh, and under medium climatic conditions, European locations, Switzerland, Japan and South Korean could be of 0.28$/kWh. If the lifetime if the system goes up, due to future technological improvements, to a very large value such as 50 years, these costs can be lowered by 10-20%. Competitiveness of grid-connected photovoltaic electricity, while it still cannot be taken for granted, is a possibility, especially if major technological advances further lowers the costs of photo cells and increases their lifetimes.

We examine the existence of the investment signaling equilibrium without assuming a specific utility function for the managers of the corporations. We assume the managers have the initial holdings of their own corporations as a form of the executive compensation. Under the different financing schemes to finance the investment, the new equity financing and the risky debt financing, we derive the investment signaling equilibrium and compare the the investment signaling equilibrium under each financing scheme. We show that the investment signaling equilibrium with each financing will obtain with the underinvestment of the high quality firm and that the investment signaling equilibrium with the risky debt financing will dominate the investment signaling equilibrium with the new equity financing.

Knowledge management has recently emerged as an appealing subject in management literature. Although its history is short, it can benefit greatly from the long history of other related disciplines in building its theories. Innovation, organizational learning, knowledge creation, organizational capability building, technology transfer and network, information technology, organizational behavior, and intellectual capital are the disciplines that have accumulated theories related to knowledge management. This paper first presents a conceptual framework that integrates three dimensions: the characteristics of knowledge (tacit and explicit), knowledge process (acquisition, creation, diffusion, storing, measurement, and application of knowledge), and the unit of analysis (individual, organization, sector, and nation). The conceptual framework produces a number of cells that need to be filled by new theories in order to understand knowledge management better. It then reviews existing theories available in the related disciplines that may be used as building blocks in constructing new theories for these cells. Finally, based on the theories available in other disciplines, the paper suggests a set of future research directions for knowledge management at the level of individual, organization, sector, and nation.
