North Korean leader Kim Jong Un decided to open 19 Economic Development Zones which are located in all over the country, as a new economic development strategy. The strategy is estimated for accepting change from socialistic planning economic system into socialistic market economic system gradually. South Korean government is busy preparing for reunification between South and North Korea. Recently, many forums and seminars for the issue, 'reunification' are held by public side as well as private sector. This study is focused on making practical strategy for developing 13 Economic Development Zones which were established in 2013 in concurrence with South and North Korea. The study assessed investment potential of the 13 zones in terms of locational, economic and legal competency from the investor's perspective of south koreans. 5 E.D.Zs, Songrim, Hyungdong, Heungnam, Chungjin, Waudo were chosen to be developed on the preferential basis. Development cooperation between South and North Korea on the 13 E.D.Zs will increase the income of north koreans in rural areas by creating jobs, contribute to boost North Korea's economic growth, and bring forward economic integration between South and North Korea.

As the Korea's economy grows bigger and its industrial structure advances, demands of high quality product become increasing. And the technology becomes to be more important factor than labor power and capital. And, the development of technology plays the key role in promoting the competitiveness of a nation. Measurement means 'Measuring with instrument', dissemination of measurement standards related with dissemination and distribution of measuring instrument. Measurement technology has been known to be the main factor of economic growth and technological development. National measurement standards is one of these factors of measurement technology. Therefore, in order to enhance dissemination of measurement standards to industry, we have to define its economic impact. We analysed the economic impact of measurement standards in terms of its contribution to the product induction of industry and management results using I-O Table with the quantitative data. The results from this study show that the increasement of measurement standards dissemination is in complementary relation with the productivity of various industries, assembly manufacturing, in particularly.

Recent urban sprawl has destroyed various kinds of green space in tile city. It has affected duality of people's life in the city, as well as urban ecosystem. Recent study shows the possibilities of roofs as green spaces in urban central site where the land costs are generally high. This research focuses on Jung-Gu district in Daegu Metropolitan city as a study area and calculates possible area of green roof using 2002 Autocad program based on aerial photographs and land registration maps. And the purpose of this research is to analyze environmental and economic effects of green roof. The environmental effects are as follows. It is expected that $91,106m^2$ green spaces, 12.13 % of study site, will be added if green roof is performed in the study site. It is assumed that the expanded areas could reduce the highest temperature to $0.5-1.0^{\circ}C$ during the summer in terms of environmental effect. And the following shows the economic effects. If green roof and greening urban central site are created as a same size of $91,106m^2$, it will be expected that the costs of green roof will be much more in-expensive than about 98 billions won. It will be also found that the expense of cooling energy can be saved out about 8 millions won per day in summer, if grass planting is accomplished on the possible areas of green roof in the study site. Therefore, it is desirable to take legal supports such as enacting regulations to activate green roof for more environmental and economic effects. For instance, green roof for public institutions, school and model area selection are desirable method to publicize the effect of greening program for citizen's participation.

Cobalt-rich manganese crusts on seamounts have received an increasing amount of attention as future resources for Co, Ni, Cu, and Mn. A dearth of detailed information regarding the relevant distribution characteristics, mining technologies, and ore processing technologies, however, has precluded potential evaluations of the technical and economic advantages of these crusts. In the past 4 years, Korea has undertaken a survey of the cobalt-rich manganese crusts in and around the Magellan Seamount and Mid-Pacific Mountains. This paper introduces the preliminary feasibility study of the distribution features and R&D results centered around the development of the cobalt-rich manganese crusts. The evaluation model was developed by modifying the model for the manganese nodules. In addition to considering the geological and geophysical differences between the manganese nodules and the cobalt-rich manganese crusts, an ore dressing subsystem was installed in the model. The mining subsystem is composed of a self-propelled collector--a pipeline with submersible hydraulic pumps for crust lifting. The smelting and chlorine leach method was selected for metallurgical processing. The production scales were established at 2,500t/y of cobalt metal. The production of three metals--cobalt, nickel, and copper--was considered in terms of metallurgical processing. The economic feasibility analyses demonstrated that the payback period was 11.4 years, the NPV was 36M$, and the IRR was 9.6% with the economic factors in the case of a cobalt price of US$ 25/lb. It was also demonstrated in this study that the payback period was 8.6 years, the NPV was 154M$, and the IRR was 14.0% in the case of a cobalt price of US$ 30/lb. This indicates that the approach under consideration appears to offer greater potential given the predicted metal prices.

The main purpose of this study was to examine the characteristics of corporate PR practitioners whose opinions were quoted as news sources and of the related articles in the economic section of the nation's three largest newspapers. The results revealed that the PR practitioners were mostly males with the job title of general manager or manager working for large electronics/IT or financing companies in Seoul and near metropolitan areas. In particular, such overwhelming features were more clearly salient in the articles related to conflicts. However, the phenomena seem to have been somewhat eased since 2002 when the newspapers came out with the specialized economic section. Analyzing the articles in terms of the channel of covering news, theme of news, and the existence of any conflict, we found statistically significant differences in the characteristics of PR practitioners. In addition, the comparison between each period before and after the emergence of the specialized economic section also showed statistically significant differences in the characteristics of the PR practitioners in many cases.

This study has developed Computable General Equilibrium (CGE) model reflecting endogenous growth economic theory, with the aim of analyzing double dividend hypothesis. This study analyzes possibility of economic growth and environmental improvement at the same time when government recycles the revenue of carbon tax to reduce existed taxes such as consumption tax, labor income tax, corporate tax. It also assesses the case of subsidy on R&D investment of renewable energy. With new and renewable generation technology adopted and disseminated, GDP loss would be lessened to a great degree. Tax recycling would provide economic gain by reducing distortion existed in the existing fiscal structure. The magnitude of economic gains from carbon tax recycling is biggest for recycling into corporate tax, and labor income tax, and then consumption tax in this order. It is also shown that double dividend effects occur in dynamic terms when government uses a carbon tax revenue to subsidize on R&D investment. At the end of the analysis period, emissions reduction would not result in GDP loss but in GDP gain. In particular, recycling into R&D increase would produce the largest and fastest GDP gain. Thus, implementing emissions reduction target would require careful consideration of economic effects by various policy instrument, including carbon tax.

The purpose of this study is to assess the extent of inequality in health outcomes and the distribution of health services according to health need under National Health Insurance System in Korea. For the empirical analysis, data were collected through an interview survey during one month of October, 1994. Interview were conducted with a total of 10, 875 of the employees and the self-employed selected through cluster, systematic sampling. The major findings of this research are as follows: 1. The analysis of the differentials in morbidity rates by socio-economic group showed that health inequality in the pro-higher groups existed in all self-reported morbidity indicators. 2. The findings of the conventional use measures showed that the lower socio-economic groups had more ambulatory and inpatient services than the higher groups. In contrast to the level of the medical care utilization, however, the higher socio-economic groups were more likely to use the high-quality source of care in terms of their treatment place compared to the lower groups. 3. By using the need-based use measures, the results were different from each use-disability ration indicator. Using the use-disability ration measured by physician visits per 100 restricted-activity days in the population, it was found that there was no evidence favoring the higher socio-economic groups. In contrast, the use-disability ration based on physician visits per a chronic patient in one year displayed that there was remarkable relative difference by income group as well as the evidence of the pro-higher income groups. 4. The results of logistic regression analysis and two-stage estimation method indicated that although the utilization is significantly affected by type and duration of insurance coverage, the use or nonuse of service and the volume of physician care consumed is determined by health need and demographic characteristics rater than economic status. In sum, these findings suggest that physician service is equitably distributed according to health need under national health insurance system in Korea. As there were some evidences of inequality including the differential in physician visits of chronic patients by income group, however, the government should strengthen the activities to guarantee the equity of health services utilization.

Baker et al. (Quarterly Journal of Economics, 134, 1593-1636, 2016) developed an Economic Policy Uncertainty (EPU) index for South Korea in the same way as the U.S. EPU Index. However, the South Korean EPU index of Baker et al. (2016) has limitations as it did not fully reflect South Korean situation in terms of keyword selection and the selection of newspapers. We develop monthly South Korean economic policy uncertainty indexes with different keywords and news media. Various analyses have been conducted in order to examine the usefulness of the newly compiled indexes.

This study looks at the reasons behind the termination of container transportation between Busan and Incheon in terms of costs structure, the division of profit, and the economic limitation faced in the domestic shipping market. The operation costs have been examined in relation to the components of logistic system of container shipping and the cost function has been estimated. The distribution proportion of operation revenue has been also investigated, considering the different components of logistics activities. In addition, the average revenue of container vessels of 144TEU and 215TEU has been calculated. Economic limitation can be analysed through the optimisation behaviour of shipping companies which tries to maximize profit or minimize loss. In conclusion, domestic short sea shipping can get the economy of scale only by transporting vessels' maximum capacity. It is also vulnerable to trucking market's fluctuation. Without the subsidy for operation, the liner in domestic short sea shipping will stop the service in order to minimize the loss.
