The purpose of this paper is to develop a port simulation program for Inchon Port. The arrival and departure data from Inchon Port are analyzed, several probability density functions for the interval time and service time are estimated, and the berthing rules are constructed based on experts experiences. The port simulation program is written in visual basic considering the interarrival p.d.f., service rate p.d.f., berthing rules, and dual-dock system, and is used to analyze the effects of the changes in ship arrival rate and service rate upon the demurrage. It is expected that we can use the simulation results in order to prepare proper service level and to evaluate the appropriate investment strategy to be planned.

It was difficult that each enterprise clearly defines PDM in domestic vehicle manufacturing industry and decides investment for the successful foundation in the mid-90s. Also, it was true that most investments to success repeat a process of trial and error even if they decide and propel. Now, PDM is not a luxurious system. Because the company is operated well even if it manages business manually, the company may not be interested in PDM introduction. Problem is business efficiency and product competitiveness. Now, we must consider that introduction and drive of PDM became necessary as instrumentation for Re-Engineering of business process concerning innovative dimension restructuring that is not reorganization, development and improvement of business for enterprise's survival. This indicates that now is when level of infra construction for an IT technology dominates competitiveness of business management. Enterprise can expect effects of PDM by implementation that manages Intellectual Properties through administration of knowledge and information finally.

The content industries environment has been undergoing significant changes due to rapid technological innovation and content market expansion. Interest in the industry is growing fast both in Asia and Europe. However, in Japan content industries are showing almost zero growth with no increase in overseas expansion. Until now, Japanese content industries have been able to grow based on domestic demands. Many different factors contributed to today's zero growth in Japanese content industries. Two main reasons are: 1) Their lack of interest in overseas expansion and 2) Insufficient investment in domestic human resources development. Considerable amounts of Japanese contents including films, music, games, and animations have been distributed in many Asian countries and today piracy problems in the region are at a serious level. According to 2004 records pirated editions accounted for 85%, 16%, 19%, and 36% in China, Korea, Hong Kong, and Taiwan respectively. Pirated editions bring economic losses to Japanese copyright profits. Making it worse, they weaken the motivation to create content and make it hard to activate cultural exchanges. Losses from copyright violations in Japanese content industries are expected to keep increasing in the future. In order to make Japan competitive and grow it is crucial to take proper measures to protect copyright infringements. This study considers the current situation of the Japanese content market, infringement issues in content which is causing many problems in Asian countries, including China, and facts about losses caused by this problem.

Interest in weekend farming has been increasing recently among city-dwellers although it is still only in the beginning stages. Weekend farming has been increasing recently among city-dwellers although it is still only in the beginning stages. Weekend farms provide people with new activities and also help to preserve green areas within the city. It is necessary to understand what weekend farm users think and what problems they encounter in order to increase the use of these farms. For this reason, we studied 16 weekend farms in Seoul managed by the Rural Guidance Office and the Agricultural Cooperative. We distributed 24 questionnaires by hand and these were later returned by mail. The questionnaire asked weekend farmers about their motivation for using the farms, about their motivation for using the farms, frequency of use, level of satisfaction, current state of housing and the sort of plants they cultivated, among other things. We found that most of them live in apartments and have little access to green areas,. Weekend farm users were generally satisfied. However, they had a lack of gardening knowledge and reported that facilities such as toilets and water service were unsatisfactory. Political support is needed from the government in order to improve weekend farms. There needs to be a wider range of farm sizes and an increase in the uses of the farms. If these improvements occur, investment in and the development of weekend farming will increase and weekend farms will take root in Korea.

With rapid expansion of the water market and growth of water companies, the recent trends in international water industry show that standardization of service activities concerning management of water and wastewater system (ISO/TC 224, to be issued in the second half year of 2007) is expected to have a large influence on the global water market including liberalization of water service market. In the Draft International Standard(DIS) of ISO/TC224, Performance Indicators(PIs) are suggested to estimate the service activities relating to water and wastewater treatment facilities. PIs have been developed in many countries including some international organization(World Bank, IWA and etc.) for service benchmarking. To evaluate public service level and establish plans to improve service level of wastewater utilities, we developed PIs for 120 items and applied them to 10 sewage utilities in the consideration of their scales, circumstances and conditions. In this study, we verified the applicability of the developed performance indicators(PIs). So, we concluded that PIs developed for the purpose of this study can be a useful tool applicable to objective evaluation of the service level of sewage utilities. Using the evaluation tool of PIs developed, it can also be used as a benchmarking tool in this industry as well as for enhancing the efficiency of operation and management of the sewage system. It will also contribute to the water resource management through determination of investment priorities based on the evaluation results and to raising international competitiveness of the domestic sewage utilities to meet the future opening of the water market.

지구온난화의 문제가 대두되면서 세계 각국이 환경친화적인 녹색성장 방안을 제시하는 가운데, 고속철도사업은 환경친화적인 글로벌 패러다임에 적합한 상품으로 부상하고 있다. 그러나 우리나라는 지난 40여 년간 도로 위주의 건설정책으로 철도분야 투자는 도로의 40~50%에 불과하며, 미국발 금융위기의 영향과 민간투자사업과 관련한 제도적 지원 미흡으로 인해 SOC 투자의 민간 비중 역시 매우 낮은 수준이다. 따라서 제한된 예산으로 효율적인 고속철도사업을 수행할 수 있도록 민간투자자의 참여를 유도할 수 있는 전략의 발굴이 요구되고 있다. 한편, 고속철도 건설사업은 향후 해외건설시장의 큰 부분을 차지할 것으로 예상되고 있으나, 우리나라는 2010년 600억 달러 이상의 비약적인 해외건설수주에도 불구, 철도 분야 수주실적은 매우 미비하여 우리 건설업체들이 해외건설시장에서 구축한 브랜드이미지와 독자적인 고속철도기술의 결합을 통한 시너지 창출이 가능함에도 불구하고 아직까지 실현되지 못하고 있다. 따라서, 해외 고속철도 시장동향 및 우리업체의 역량수준 분석을 통한 건설업체 관점의 해외 고속철도사업 진출전략의 수립이 필요한 실정이다. 이에 본 연구는 국내 고속철도시장의 활성화를 위한 민간투자자의 참여유도 방안을 수립하고, 해외고속철도사업 진출을 위한 컨소시엄 모델 정립 및 제도적 정책적 국내 국외시장 지원방안을 도출하기 위해 고속철도사업의 영역을 국내와 해외로 나누어 자료수집 및 동향 분석 등을 개별적으로 수행하였으며, 고속철도 분야에 대한 건설업체의 인식수준 및 니즈, 활성화 전략의 실효성 검토를 위한 설문조사 및 업계 전문가 심층 면담을 함께 실시하였다. 본 연구에서 도출된 활성화 및 참여확대 방안은 1) BTL방식의 철도사업 추진 및 민간의 참여 유도를 위한 부대사업 관련 법률 개정, 2) 민간선투자제도의 활성화를 위한 업체의 신용도에 따른 팩토링 금리 수준의 인센티브 수준 상향 조정, 3) 호남~제주 해저고속철도사업의 추진, 4) Total Service제공을 위한 신흥시장 진출 컨소시엄 모델의 정립, 5) 고속철도 기술의 해외진출 및 우리 업체들의 해외참여 확대를 지원하기 위한 한국철도협회의 역량 제고, 6) 글로벌 인프라펀드 규모의 확대이며, 이와 같은 전략추진을 통해 국내 고속철도시장의 활성화 및 우리 업체들의 해외사업 참여확대를 기대할 수 있을 것이다.

This research was designed to compare the health condition and the quality of life of the elderly inpatients with those of the normal elderly people. The subjects of study were 482 elderly inpatients and 304 normal elderly people. The research was conducted in July and August using the instrument WHOQOL. The results of the research are as follows: For the level of health, it was recognized that male was healthier than female, having higher the education, living in the city rather than in the rural, keeping the normal life than being in the hospital. There were little difference in the past medical histories of the elderly inpatients and the normal elderly people. As to the diseases currently under the treatment, there were some difference between the elderly inpatients and the normal elderly people but the tendency was similar in the kinds and the frequencies. As to the recognition for the quality of life between the elderly inpatients and the normal elderly people based on the records reflected on each of the domains of WHOQOL, the normal elderly people more positively recognized in the overall quality of life and the following domains: physical, psychological, level of independence, and spirituality/religion/personal beliefs. The normal elderly people more positively recognized especially in the level of independence domain (mobility, activities of daily living, dependence on medication or treatments, working capacity). In the social relationships domain only the sexual activity was significant and the normal elderly people more positively recognized. The elderly inpatients showed the correlation of over 0.5 in the overall quality of life and the following domains: environment, social relationships, physical, psychological, level of independence. It was over 0.6 in the physical domain and the domains of psychological and level of independence. and the psychological domains of level of independence and social relationships. For the points of overall quality of life, it had no correlation with hospitalization but the health condition, residential district, occupation, and taste exerted a significant effect. As a result of separate analyses of the elderly inpatients and the normal elderly people, the health condition and the age only were the common variable which would exercise a significant effect. Besides, the primary factors which would exercise the quality of life were the occupation and taste for the elderly inpatients, and the residential district and source of income for the normal elderly people. In conclusion, it is first and foremost important to improve the standard of health for the overall quality of life for the elderly people, regardless of hospitalization. Therefore, a plan must be urgently drawn up for revitalization of the health promoting projects for the elderly people and the public health projects for the elderly people, and the investment must be increased for settlement of health problems of the elderly people.

The objective of this paper is to investigate the impact of economic growth (per capita real GDP), the square of per capita real GDP, energy use, financial development (FD), and foreign direct investment (FDI) on ecological footprint (EF) in the case of Malaysia over the period 1971-2014, by employing the ARDL approach. The long-run results revealed that economic growth has a significant positive impact on the ecological footprint and it implies that the economic growth deteriorates the environmental quality in Malaysia. Conversely, the square of GDP showed a negative and significant impact on the EF in the long run. As the coefficient of GDP in our study is positive and statistically significant while the coefficient of squared GDP is negatively significant, thus, this study supports the presence of the environmental Kuznets curve (EKC) hypothesis in the case of Malaysia. Furthermore, the result indicates that FDI has a positive and significant impact on the EF in the long run, which means a rise in FDI will enhance the environmental pollution level. Thus, it confirms the pollution haven hypothesis. Hence, it suggests that Malaysia imposes stricter environmental policies. Further, FDI and FD are causing GDP in Malaysia, but through increasing EF.
