Korean government is investing 1.8 billion won on infrastructure and investment on PPP projects constitutes 16.3%. This phenomenon is to promote private investment as well as lessening government burdens of public budgeting. However, the only criterion to be considered is government financial status in selecting public or private highway investment projects. So systematic decision support model is required in choosing public or private highway investment projects. So, this paper suggests a systematic decision support model for deciding public or private highway investment at the early stage of project planning. Furthermore, this paper identifies key decision variables with respect to economic, politic, project management criterions based on the related literatures and feedbacks from experts. This paper analyzed 30 cases of government investment and PPP projects and got the survey result from highway specialists. As a result, this paper presents an interval with respect to economic criteria using mean and standard deviation and a logistic regression equation which can predict the possibility of PPP project. Through this study, decision maker of central or local government can decide public or PPP highway project more systematically and reasonably.

The study is focused on comparing the perception of forest investment by two types of forest owners, ordinary forest owners (OFOs) and forestry successors and model forest owners(FSMFOs). The results show that FSMFOs' perception of forest investment is relatively high compared with OFOs' perception. The details are as follows; 1. In the general status, the education and income levels of FSMFOs are higher than those of OFOs, and FSMFOs are engaged in various kinds of jobs while OFOs are inclined to lean toward farming. 2. Of the motives to own forests, partial-purchase and -inheritance is the most of FSMFOs(41.2%) and inheritance the most of OFOs(40.9%) 3. The number of FSMFOs who had made forest investment and applied government support is more than that of OFOs. 4. FSMFOs know government support better than OFOs do, while both show lukewarmness on weather the support is carried out according to the rules.

Many economists and policymakers regard the ratio of R&D investment to GNP to be a good indicator of a nation's technological capabilities. Consequently, their major policy recommendation to promote technological development is a rapid expansion in R&D investment. However, a low R&D ratio does not necessarily mean less efforts at technological advancement since the composition of technologies to be developed varies depending upon the stage of economic development. Technology policy to improve the international competitiveness of domestic industries should be based on the stage of economic development and present technological status rather than on a simple comparison with advanced countries. At Korea's stage of development, maximizing the efficiency of R&D investment is more important than enlarging the size of the investment. Strategic alliances between domestic firms and foreign enterprises should be encouraged to save time and costs involved in acquiring new technologies and learning how to use them. The government should establish institutional devices to stimulate private enterprises to internationalize their business activities such as R&D, production, and marketing. The government should also promote the development of domestic and international R&D networks, which can serve as the infrastructure for technological innovations.

The purpose of this study was to analyze the effects of workers' human resource development and their recognition of human resource on-the-job satisfaction. A sample of 4,727 workers that was selected from Korea Labor Panel Data was analyzed by t-test and multiple regression, and was tested by causal effects among related variables. The major findings were as follows: First, the workers' recognition of their job performance level vs. educational attainment was affected by their annual income, job status, educational attainment, gender, and experiences of human resource development. Second, the workers' job satisfaction was affected by gender, age, educational attainment, health status, job status, annual income, experiences of human resource development, recognition of their job performance level vs. educational attainment, and recognition for their job availability. Third, the factors that had a causal effect on workers' job satisfaction were educational attainment, gender, age, health status, annual income, and experiences of human resource development. Above all, workers' educational attainment had a strong direct effect on job satisfaction, and annual income had a strong indirect effect on it. From these findings, it can be concluded that workers' effort and trial for development and investment of human resource played an important role in increasing job satisfaction.

Global status of aquaculture and aquaculture scientific journals is briefly described. Asia is the centre of fishing and aquaculture activities but most publishers, editors and editorial board members of fisheries and aquaculture journals are from Europe and/or USA. The contribution by Asian fisheries/aquaculture scientists to these journals remains low. Language barrier and requirement for monitory investment seem to inhibit Asian participation in this realm of scientific activity. The need for glob-alization of aquaculture scientific journals is emphasized. Selected strategies, which are adopted by the Western journals to improve their image and management, are indicated.

We have examined and analyzed the status of policy, R&D investments, patents and market share of medical imaging technologies for major countries including Korea, the United States, Japan and European Union. ]Korea is mostly inferior compared to the others in priority of industrial policy, R&D investment, research manpower, number of patents, technological level and world market share. However, Korea can recover competitiveness, if there are intensive government supports for this technology.

We have examined and analyzed the status of policy, R＆D investments, patents and market share of physiological signal measurement technologies for major countries including Korea, the United States, European Union and Japan. Korea is generally inferior to the others in terms of priority of industrial policy, R＆D investment, number of patents, technological level and world market share. However, Korea could recover competitiveness, with intensive government supports for this technology.

Background: Owing to the increase in the aging population, the health problems of the elderly have become important social problems. Social support has a positive effect on improving the quality of life and prolonging the life of elderly people. It is one of the major factors that affects the oral health status of elderly people. The purpose of this study was to examine the relationship between oral health status and social support in elderly people using representative data. Methods: In this study, data from a community health survey in 2015 involving 63,929 elderly people aged over 65 years were analyzed. T-test and ANOVA analyses were performed to compare the general characteristics of and perception about social support. Additionally, a linear regression analysis was performed to confirm the relationship between perceptions about social support and subjective oral health status. Results: We found that sex, age, household income, education level, the presence of a spouse, existence of an unmet dental need, and regular oral check-up had a significant effect on subjective oral health status (p<0.05). In addition, when controlled for all factors, social support has a significant impact on subjective oral health status. Conclusion: The findings indicate that social support is associated with the subjective oral health status of Korean elderly. This suggests that community-level or government investment is required to improve the oral health of the elderly. In particular, policy interventions such as the establishment of facilities that promote social networks, especially facilities based on friendship networks, are needed.
