The demand for fuel and energy resources continues to grow due to increased consumption and emerging economies in all parts of the world. With this increase in demand, crude oil prices in the international market has jumped dramatically. Global warming, which is a consequence of increasing greenhouse gas (GHG) emissions, has become scientific, social, and political concerns. To cope with global warming and energy crisis, cost-competitive biofuels are urgently needed. In addition, development of an infrastructure, which supplies energy stably and diversifies energy resources, as well as new cost-saving technologies should be developed to reduce the costs of producing biofuels. Due to high oleic acid content, rapeseed (Brassica napus L.) is currently the potential feedstock for biodiesel production in temperate zone region and the production and use of rapeseed oil is already commercialized in Europe. In Korea double-cropping (rice and rapeseed) became more prevalent because it reduces competitions from land constraints. Production of rapeseed as a biodiesel feedstock may reduce the influence of rising oil prices and nation's dependence on imported petroleum and increase job opportunities and farm incomes.

For the district heating and cooling business, it is required to install energy-saving facilities using energy from waste and land fill gases such as combined heat and power(CHP). The current issues that this business faces can be summarized as below: which facilities including CHP can be economically introduced and how much of their capacities should be. Most of such issues are clearly related to the optimal plant design of the district heating and cooling business, and the prices of energy services such as heating and cooling energy, and electricity. The purpose of this study is to establish linear program model of least cost function and to practice the empirical test on a assumed district heating and cooling business area. The model could choose the optimal type of energy-producing facilities among various kinds available such as CHP's, absorption chillers, the ice-storage system, etc. CHP with the flexible heat and power ratio is also in the set of available technologies. And the model show us the optimal ration of heat producing facilities between CHP and historical heat only boiler in the service area. Some implications of this study are summarized as below. Firms may utilize this model as a tool for the analysis of their optimal size of the facilities and operation. Also, the government may refer the results to regulate resonable size of business.

The purpose of this study is to critically evaluate the DPD development plan of Kyungpook province, which was established in 1996 and slightly revised in 1997 in terms of a theoretical framework, fair distribution and ecological sustainability, and the feasibility of capital supply of the proposed plan. The early part of the proposed plan introduces various theories and approaches developed in regional (or local) development planning as a general after the 1970s. However, the theories and approaches mentioned are not used as a guideline to establish the DPD development plan of Kyungpook province as a historically developed particular place. Most of the plans were tourism-oriented and did not seriously take the local characteristics into account. All the DPDs of Kyungpook province are located in the upper parts of the Nakdong River basin. So those regions are ecologically vulnerable. But a lot of problems remain concerning the environmental impacts of the proposed development plan. In terms of fair distribution and ecological sustainability, it seems that the DPD development plan was routinely made by a handful of professors and administrators, based on a standard format of regional (or local) development as a genera]. Finally, capital is the key factor for successfully implementing the DPD development plan. It came from the national and local government and private investors. The government have generally financed the construction of infrastructures, not profit-oriented projects such as tourism and resort businesses. However, the feasibility of private capital was not carefully examined in the plan.

This paper aims to present the ways to maximize educational effects and facilitate a curriculum renovation through the Specified Track Curriculum Development, a joint lecture system among local universities which is implemented by Busan Educational Alliance of Mechanical Engineering (BEAM) as part of New University for Regional Innovation(NURI), a government-sponsored project to facilitate a balanced regional development of Korea. The Specified Track Curriculum is a unified governing body joined by 4 universities of mechanical engineering departments with an emphasis on their specified academic fields(advanced hightech, environmental, marine and foundational machinery sectors), And the universities mutually recognize academic credits. The track (Specified-Track Curriculum) was carried out three times from winter semester in 2005 to the present and 486 students took the track course for two years. As a result, the track laid out a foundation for the first local joint lecture system in korea with the performance-oriented and students-tailored education, meeting needs of the new era and training efficiency. The graduates' employment rose to 8.5%, compared with that of 2005. According to recent survey conducted on companies employing the graduates, the satisfaction with the graduates' performance marked 9.4% improvement. The track also contributed to expanding human networks, facilitating the educational exchange of local universities.

Open Source Software (OSS) is a new paradigm for software development. The system is based on the notion of giving software (including sources) away for free, and making money on services, customizing and maintenance. For these reasons, many software companies have considered adopting and using OSS in Software R&D. A variety of factors may influence the use of decision making of OSS. The objective of this study was to explore the significant factors affecting the use decision of OSS and the job performance of OSS usage in software R&D. A research model was suggested based on the TOE Framework and Information Systems Success Model. These findings show that technical benefits of OSS have significant effects on OSS use. The technical benefits of OSS, and organization context, in turn, have significant effects on the use of OSS. On the other hand, the technical risks of OSS and the environment context have no effects on OSS use. In addition, OSS use and user satisfaction have significant effects on the individual job performance. This research contributes towards advancing the theoretical understanding of the OSS Benefits and Performance in Software Development.

The Clean Development Mechanism (CDM) is the multi-lateral 'cap and trade' system endorsed by the Kyoto Protocol. CDM allows developed (Annex I) countries to buy CER credits from New and Renewable (NE) projects of non-Annex countries, to meet their carbon reduction requirements. This in effect subsidizes and promotes NE projects in developing countries, ultimately reducing global greenhouse gases (GHG). To be registered as a CDM project, the project must prove 'additionality,' which depends on numerous factors including the adopted technology, baseline methodology, emission reductions, and the project's internal rate of return. This makes it difficult to determine ex ante a project's acceptance as a CDM approved project, and entails sunk costs and even project cancellation to its project stakeholders. Focusing on hydro power projects and employing UNFCCC public data, this research developed a prediction model using logistic regression and CART to determine the likelihood of approval as a CDM project. The AUC for the logistic regression and CART model was 0.7674 and 0.7231 respectively, which proves the model's prediction accuracy. More importantly, results indicate that the emission reduction amount, MW per hour, investment/Emission as crucial variables, whereas the baseline methodology and technology types were insignificant. This demonstrates that at least for hydro power projects, the specific technology is not as important as the amount of emission reductions and relatively small scale projects and investment to carbon reduction ratios.

In the 4^th Industrial age, mobile games are a highly competitive but highly profitable industry, with hundreds of games per day. To produce a successful mobile game, it is necessary to understand the mobile environment and consumers in the mobile era, and a study that can provide implications for the importance of various factors is needed. The purpose of this study is to explore the in- and out-of-game factors that influence the success of mobile games and to examine the relationship between these factors and customer satisfaction and loyalty. As a result, the game platform's system quality and service quality had a positive effect on the evaluation, and the price policy did not have a significant effect on the evaluation. Also in the flow factor, goal and interaction (relationship) had a positive effect on the flow, and skill or challenge did not have a significant effect. The effects of flow and platform evaluation on customer loyalty were all positively affected. First. Companies must derive customer opinions and actions about the game through continuous interaction with customers. Second, if the game gives customers the proper goals and functions to enable the interaction between users, more successful games can be developed.

South Korea started to actively participate in the ODA project across Asia, Africa, the Middle East, CIS countries, and Latin America as it transitioned from a country receiving developmental aid to a donor country. As more and more recipient countries are looking into the e-government model of South Korea, a new approach to the Korean model is being investigated. Various promotions were made, ranging from the implementation of the e-government ODA project, review of its feasibility to evaluation of the results. In order to improve and maximize performance management OD projects, it is necessary to look into the analysis of its follow-up results. In this study, practical performance management and policy implications were explored, focusing on the e-government ODA project. In particular, a case study analysis was attempted with focus on the Nigerian e-government project promoted as part of the project. It focused on Korea's e-government linkage process, implementation procedures and strategies applied when establishing the e-government master plan and suggested the necessity of an approach suitable for new environmental changes. In terms of sustainability of the ODA project, it is necessary to build a Korean e-government model that reflects the new intelligence information technology.

The secondary health status of the disabled is more vulnerable due to the aging of the disabled, the nature of primary disabilities, and social and environmental disability suppression and stress. Therefore, this study aimed to examine the experiences of secondary disabilities of the disabled and how they responded when secondary disorders occurred. A total of 13 people with severe disabilities with secondary disabilities were interviewed in a focus group and analyzed by applying phenomenological research methods. As a result of the analysis, people with disabilities were experiencing secondary disorders due to variations in the experiences of aging and primary disorders, management problems and life accidents in the primary disorder, misunderstanding of the labor market for disorders and health, misunderstanding of risks of secondary disorders and lack of prevention. In response, people with disabilities live alternatively between body and work, body and academic, try to prevent worsening of secondary disabilities at the individual level, continue to enter the hospital, or choose a life that puts health first. While experiencing secondary disabilities, people with disabilities experienced the threat of life, recognized life as having to endure and fought to the end, acknowledged the difference between the disabled and non-disabled people, and standed aloof from their ongoing secondary disability. It also requested institutional support. Based on the results of this study, medical-level measures, institutional support measures in the labor market, and social welfare practices were discussed.
