A comparative study was made about health resources, medical care service statistics and public health service statistics by health subcenters at Jangdong and Jangpyung townships, Jangheung County, Chollanamdo before and after the unification of two health subcenter to improve their function. 1. While two general physicians, one dentist, 4 nurse aids arid one oral hygienist were working at two health subcenters with simple facility with examination room and public health office in 1997 prior to the unification, in 1999 after the unification of two health subcenters 14 staff including a specialist physician, a general physician, a dentist, a herb hygienist, a radiology technician and a physical therapist were working in the new health subcenters equipped with appropriate facilities in two storey building. 2. In 1997 before the unification the yearly total income of two health subcenters was 78,815 thousand won(about 14,000 won per capita) and the amount was 140,376 thousand won(about 25,000 won per capita) in 1999 after the unification. And the income was used for operation of health subcenters excluding personnel expense. 3. While 90.5% of visitors to the health subcenters came for general medical care, and 91.6% came for the revisit before the unification, after the unification 71.2% came for general medical care, 10.8% for dental care, 16.5% for oriental physician's care, 29.7% for the first visit and 70.3% for revisit. Most common problem cared for was musculoskeletal disorder like arthralgia. Average treatment cost per person per month was 9,363 won before the unification and 8,309 won after the unification. 4. Through the comparison of execution rate of public health services before and after the unification. the practice rate of most health service among target population including visiting service for chronic illness, maternal and child health service and immunization service increased after the unification. The practice rate of tuberculosis control service, hypertension control and diabetes management was a little decreased. In conclusion, continuous effort to satisfy all persons in two townships and evaluation are necessary to coincide with the spirit of unification of two health subcenters.

In order for the users (shipping firms and shippers) and suppliers (stevedoring firms) in the container terminal industry to win-win, it is necessary to have some appropriate diverse market conditions for the industry. This study analyses the basic conditions and demand and supply characteristics of the industry and investigates the market performance of Busan container ports. First, this article analyses the basic characteristics of demand and supply. As the demand characteristics, there are five ones such as 1) exogeneity of demand, 2) function as export/import transportation and hub for transshipment, 3) increase of users' bargaining power, 4) high substituting elasticity, 5) reduction of volume growth. As the supply characteristics, there are seven ones such as 1) inelasticity of supply, 2) homogeneity of stevedoring services, 3) over-supply, 4) adoption of cutting-edge stevedoring technology, 5) scale economy and impossibility of storage, 6) labor market rigidity, 7) enhancing port's role in SCM. In addition, this study conducts the so-called structure-conduct-performance analysis. For the structure analysis, 1) lacks of scale economy in stevedoring companies, 2) high entry barrier, 3) strengthening of shipping firms' bargaining power, 4) transitory permission scheme for tariff are analyzed. For the conduct analysis, 1) price discrimination between export/import and transshipment, 2) mid-term length of terminal use contract, 3) continuous investment in equipment, 4) low level of cooperation among terminal operating firms are derived. For the performance analysis, 1) inequality in profitability, 2) reduction of export/import cost, 3) delay in adopting cutting-edge technology, 4) idle equipment are analyzed. Following this logical flow, the hypothesis that the market structure influences the market conduct is tested based on the actual dataset. As a future agenda in the conclusion, this article recommends the so-called port industrial policy.

Purpose: The recent increased use of Personal Mobility (PM) has been accompanied by a rise in the annual number of accidents. Accordingly, the safety requirements for PM use are being strengthened, but the laws/systems, infrastructure, and management systems remain insufficient for fostering a safe environment. Therefore, this study comprehensively searches the main problems and improvement methods through a review of previous studies that are related to PM. Then the priorities according to the importance of the improvement methods are presented through the Delphi survey. Method: The research method is mainly composed of a literature study and an expert survey (Delphi survey). Prior research and improvement cases (local governments, government departments, companies, etc.) are reviewed to derive problems and improvements, and a problem/improvement classification table is created based on keywords. Based on the classification contents, an expert survey is conducted to derive a priority improvement plan. Result: The PM-related problems were in 'non-compliance with traffic laws, lack of knowledge, inexperienced operation, and lack of safety awareness' in relation to human factors, and 'device characteristics, road-drivable space, road facilities, parking facilities' in relation to physical factors. 'Management/supervision, product management, user management, education/training' as administrative factors and legal factors are divided into 'absence/sufficiency of law, confusion/duplication, reduced effectiveness'. Improvement tasks related to this include 'PM education/public relations, parking/return, road improvement, PM registration/management, insurance, safety standards, traffic standards, PM device safety, PM supplementary facilities, enforcement/management, dedicated organization, service providers, management system, and related laws/institutional improvement', and 42 detailed tasks are derived for these 14 core tasks. The results for the importance evaluation of detailed tasks show that the tasks with a high overall average for the evaluation items of cost, time, effect, urgency, and feasibility were 'strengthening crackdown/instruction activities, education publicity/campaign, truancy PM management, and clarification of traffic rules'. Conclusion: The PM market is experiencing gradual growth based on shared services and a safe environment for PM use must be ensured along with industrial revitalization. In this respect, this study seeks out the major problems and improvement plans related to PM from a comprehensive point of view and prioritizes the necessary improvement measures. Therefore, it can serve as a basis of data for future policy establishment. In the future, in-depth data supplementation will be required for each key improvement area for practical policy application.

To effectively lead "Innovative City Season 2", it is important to investigate whether the creation of an innovative city has a positive effect on the revitalization of the hinterland town economy. This study explores the effects (external effects) of increases in the number of workers at public institutions in the innovative city of Jeollabuk-do, located closest to the hinterland town (Jeonju-si). In the results, we show that increases in the number of workers positively affected the commercial real estate market, which is one of the barometers that show the revitalization level. On the other hand, the effect was found to be limited to the new downtown commercial real estate market with good accessibility and modernized facilities and services. This suggests that the innovative city adjacent to the hinterland town meets the purpose of the innovative city to some extent by generating a positive external effect, especially in accessible and modernized areas. To further expand the positive spillover effects of an innovative city on the hinterland town, it is necessary to expand public institutions for relocation, improve settlement conditions, and establish a practical cooperation system between specialized public institutions and hinterland-related industries.

It's vital to establish the competitive comparative advantage as the competitions among global logistics companies have become fierce. The global companies, hence, must innovate their Port Hinterland to hub and spoke in a view of SCM. The Port Hinterland significantly affects its local economy and value added. The task of the Port Hinterland nowadays is to improve its efficiencies by utilizing logistics operations and services. The Korean government has planned to reduce the scale of the Port. The CCR and BCC matrices show that there are nine efficient companies: two companies in Gwangyang Hinterland and five companies in Busan Hinterland, though Masan FTZ was only ranked on the 24th, on the rank of world FTZ. This paper aims at finding the cargo volume necessary for achieving the maximum efficiency. This research proposes an appropriate strategy to keep a certain amount of cargo volume stable and presents the Port Hinterland differentiation strategies of Gwangyang and Busan.

Generally, electricity market has monopoly market structure because of need of enormous investment for infrastructure. However, the introduction of competition in network industry as electricity is a tendency of the world with decreasing the effects of economy of scale due to the advancement of technology. Now, electricity industry restructuring is in progress but the competition in electricity retail market is not in force yet in Korea. Whether a effective competition exist or not is very important to policy decision maker who drive restructuring, but there are small numbers of quantitative researches on that. In this study, we estimated the effectiveness of competition in the electricity retail market through switching costs. If switching costs are high, consumers actually can be locked in incumbent firm in spite of introduction of competition. Therefore switching is a critical factor to determine effectiveness of competition and to estimate the size of switching costs quantitatively can proffer the information about whether the competition in the electricity retail market is effective or not in the future. We estimated switching costs using consumer' stated-preference data by conjoint analysis. In according to estimation results, the cost of switching process is not so high, but the relative brand loyalty of an incumbent company is significantly high. And the price is considered as the most important factor choosing an electric service commodity. Based on the empirical results, it is possible to analyze the relationship between suppliers' competitiveness resulted from management efficiency and customers' switching possibilities. The paper therefore provides guidance for suppliers in deciding to enter into retail competition and for policy makers in introducing retail competition. And it has a significance of estimating the switching costs directly.

The cultural contents are a field that originally has a cycle ranged from producers of various contents and distribution consumption. The various object elements composing of an ecosystem of cultural contents in this cycle, and the search of harmonious relations between these objects is becoming an important issue. The ecological approach on the cultural contents field is not being tried authentically until now, in spite of the expansion of interest and usefulness from its application at present, so there is no detailed discussion on the inside of an ecosystem and itsaction such as confirmation of object elements composing of the ecosystem, interaction principles between objects and object development, principles of co-evolution, etc. achieving common development of all objects composing of the ecosystem. Therefore, the present research aims to confirm object elements composing of the ecosystem of cultural contents through an ecosystem model that has been researched in several fields of the ecosystem and social science, and to seek interaction between objects and each object as well as a development direction of a total ecosystem.

This research is to explore food waste management across local governments. In particular, pubic administration on food waste, food waste management (from generation to disposal) and civil complaints in jurisdiction are examined. In doing so, a self-administered questionnaire survey was conducted among civil officers in charge of food waste management, and all the collected responses were statistically analyzed. The main results were as follows: public spending on food waste management was a little larger in metropolises than in provincial cities, and the largest food waste source was identified as households (in housing). While regular collection of food waste by trucks was the most common transport method adopted by local governments, resource recovery for compost/fertilizer production was widely used. Also, most of the respondents agreed that the current approach to food waste handling practices are necessarily replaced with more advanced technology converting waste into energy or fuel. Further, it's found that the civil complaints on food waste management were largely categorized into 3 groups - food waste handling, civil service and food waste retrieval. Therefore, the findings indicate that the development and application of no-food waste or waste-to-resource systems are effective in housing estates where large amount of food waste is generated and eliminated.

Recently, Korean medium-sized medical organizations require innovative strategies. Network-driven concerns in Korean medical organization have been a front burner issue to enhance economic and managerial efficiencies. Effective network-driven collaboration depends upon effective processes and economics strategies among medical providers group. From this motivation, we studied and provided the systems' theoretical background and networked hospital system structures. The aim of suggested research model in this paper is to overcome demerit of stand-alone medium-sized hospitals and analyze a system dynamics model to measure managerial performances. The developed system dynamics model is to quantify the effects of network strategy based on the historical financial data of real-life hospitals network experiences. The network effects are resulted in efficiencies and effectiveness enhancements in competitiveness through advertisement and effective education system. The simulations of system dynamics results can explain the improvement in financial outcome by joining in the network group. The network effects are shown more effective in dental hospital than other groups. In conclusion, it is expected that network effects have a critical influence of managerial, marketing, and medical collaboration performance for any type of medical hospitals.

Purpose: This study empirically investigates the utilization and expenditure of health care and long-term care at the last year of life for long-term care beneficiaries in Korea. Methods: This study used National Health Insurance and Long-term Care Insurance claims data of 271,474 LTCI beneficiaries, who died from July 2008 to December 2012. Their cause of death, place of death, health care costs, and the provision of aggressive care were analyzed. Results: Cardio-vascular disease(29.8%) and cancer(15.3%) were reported as their major cause of death, and hospital(64.4%), home(22.0%), social care facility(9.2%) were analyzed as the place of death. 99.3% of subjects used both health care and long-term care during the last 1 year of life. The average survival period were 516.2 days after they were LTCI beneficiaries. The health care expenditure gradually increased near the death, and the last month were three times more rather than the first month. Furthermore, 31.8% experienced some aggressive cares(CPR, blood transfusion, hemo-dialysis, etc.) at the last month of life. Conclusion: The results of this study suggest that it is important to develop the end of life care policies(for example, hospice, advanced care directives) for the LTCI beneficiaries. They might contribute to the improvement of quality of life and the reduction of health care expenditure of the elderly at the end-of-life.
