This study analyzes the effects of aging workforce on human capital and the per capita gross regional domestic product, using regional panel statistics from 1995 to 2017. According to the results of the two-stage least-squares panel regression analysis reflecting the fixed effects by region, the aging of the labor force had no effect on the human capital employment ratio and per capita gross domestic product in the metropolitan cities, but reduced human capital and per capita gross domestic product in the provinces. The share of service businesses had a positive effect on human capital in metropolitan cities, but the effect was not significant in the provinces. Human capital significantly contributed to the increase in per capita gross regional domestic product in the metropolitan cities, but the physical capital stock significantly contributed to the increase in per capita gross regional domestic product in the provinces. The results of this study suggest that the human capital job policy and the per capita regional GDP growth policy due to the aging workforce may be different between metropolitan cities and provinces.

The aim of this study is to examine the relationship between globalization and income distribution in Korea. In order to identify the key determinants, the study investigates the effects of trade openness, inward and outward FDI flows, and per capita GDP on income distribution. The study uses methodology of unit root and co-integration technique as well as an error correction model over 1992 to 2011 by using annual data. The empirical findings showed that income inequality is reduced as trade openness and the per capita GDP increase. Meanwhile, income inequality is deteriorated as inward and outward FDI flows increased. In addition, the study revealed that the negative effect of inward FDI flows on income inequality is greater than that of outward FDI flows. This result supports the Feenstra and Hanson (1997) hypothesis. Overall the globalization process can be beneficial for the Korean economy, but its nature should be closely monitored regarding income distribution.

It is known that the number of astronomers of a country registered to the International Astronomical Union (IAU) is correlated with that country's gross domestic product (GDP). However, the robustness of this relationship could be doubted, as the fraction of astronomers joining the IAU differs from country to country. Here we revisit this correlation by using more recent data, updated as of 2017. We find a similar correlation by using the total number of astronomers and astrophysicists with PhD degrees that are working in each country, instead of adopting the number of IAU members. We confirm the existence of the correlation. We also confirm the existence of two subgroups within this correlation. One group consists of advanced European countries having a long history of modern astronomy, while the other group consists of countries having experienced recent rapid economic development. In order to determine the cause for the correlation, we obtained the long-term variations of the number of astronomers, population, and the GDP for a number of countries. We find that the number of astronomers per capita for recently developing countries has increased more rapidly as GDP per capita increased, than that for fully developed countries. We collected demographic data of the Korean astronomical community and find that it has experienced recent rapid growth. From these findings we estimate the proper size of the Korean astronomical community by considering Korea economic power and population. The current number of PhD astronomers working in Korea is approximately 310, but it should be 550 in order for it to be comparable and competitive to the sizes of the Spanish, Canadian, and Japanese astronomical communities. If current trends continue, this number will be reached by 2030. In order to be comparable to the German, French, and Italian communities, there should be 800 PhD astronomers in Korea. We discuss ways to overcome the vulnerability of the Korean astronomical community, based on the statistics of national R&D expenditure structure in comparison with that of other major advanced countries.

Does financial development contribute to economic growth? The literature finds that an expansion in financial resources is useful for economic growth if the degree of financial development is under a certain threshold; otherwise, the expansion is detrimental to growth. Almost every published study, however, considers country-panel data. Accordingly, the results are not directly applicable to the Korean economy. By examining Korean time-series data, this paper finds that there is an inverse U-shaped relationship between the per capita real GDP growth rate and private credit (as a percentage of nominal GDP)-a well-known measure of quantitative financial development, where the threshold is 171.5%. This paper also finds that private credit is positively associated with economic growth if the share of household credit out of private credit is less than 46.9%; otherwise, private credit is negatively associated with economic growth. As of 2016, the ratio of private credit to GDP and the ratio of household credit to private credit are both higher than the corresponding thresholds, which implies that policymakers should place more emphasis on qualitative financial development than on a quantitative expansion of financial resources.

Detailed analyses of total health expenditure and its sub­categories are essential for the evidence­based health policy(EBHP). These analyses, again, should be based on timely and reliable data that are comparable across countries. The System of Health Accounts (SHA), published by the OECD in 2000, provides an integrated system of comprehensive and internationally comparable accounts. The author has implemented the SHA manual into Korean situation, and examined overall expenditure estimate and its basic functional breakdown following the manual. This study explains how pharmaceutical expenditure is estimated. The results are, then, analyzed particularly from the international perspective. Both administrative data in Statistical Yearbooks (National Health Insurance, Medical Aid, Industrial Accident Compensation Insurance) and survey data on Health and Nutrition are used for the estimation. Per capita pharmaceutical expenditure in Korea (183 US$ PPPs) was far less than the OECD average (308 US$ PPPs) in 2001, but pharmaceutical expenditure share in total health expenditure (20.3％) was higher than the average (16.7％). This can be explained by the fact that there is a statistically significant correlation between pharmaceutical expenditure share and per capita GDP of each country. Korean people follow the tendency of relatively low­income countries to spend less than OECD average for health care, but follow again their tendency to spend more on drugs than on other health care services. In consideration of results and analysis as above, per capita pharmaceutical expenditure in Korea is expected to grow in the future, but the growth rate of the pharmaceutical expenditure is expected to be less than that of overall health expenditure.

The primary purpose of this study is to analyze the impact and determinants of bilateral Free Trade Agreements on international total bulk shipment trade volume at the port of Korea using the Panel Gravity Model. The model estimates the aggregated panel data of exports and imports (excluding transshipment) as a dependent variable during the period from 1996 to 2015. GDP, GDP per capita, distances between bilateral countries, and FTA dummies are included as independent variables. And the economic integration of FTAs including ASEAN+3 and NAFTA3 countries were used as dummy variables. Study results show that GDP and GDP per capita have positive impacts on bulk shipment trade volume at the port of Korea. In addition, Korea's bilateral FTAs with Singapore, India and the United States have positive effects on total bulk trade volume in Korea. This is the so called trade creation effect. On the other hand, ASEAN+3 and NAFTA have negative effects on the total bulk trade. This is the so called trade diversion effect. Also, the distance between Korea and its trade partners has a negative impact. These findings provide insights for: further academic research, site operators who work in related trade and maritime sectors, and policy makers engaged in port and maritime operations. The results can be used to develop strategies for maximizing bulk port throughput.

Background: Mammography is considered the gold standard of breast cancer mass screening and many countries have implemented this as an established breast cancer screening strategy. However, although the incidence of breast cancer and racial characteristics are different between Western and Asian countries, many Asian countries adopted mammography for mass screening. Therefore, the objective of this research was to determine whether mammography mass screening is cost-effective for both Western and Asian countries. Materials and Methods: A systematic review was performed of 17 national mammography cost-effectiveness data sets. Per capita gross domestic product (GDP), breast cancer incidence rate, and the most optimal cost-effectiveness results [cost per life year saved (LYS)] of a mammography screening strategy for each data set were extracted. The CE/per capita GDP ratio is used to compare the cost-effectiveness of mammography by countries. Non-parametric regression was used to find a cut-off point which indicated the breast cancer incidence rate boundary line determining whether mammography screening is cost-effective or not. Results: We found that the cost-effective cut-off point of breast cancer incidence rate was 45.04; it exactly divided countries into Western and Asian countries (p<0.0014). Conclusions: Mammography screening is cost-effective in most of Western countries, but not in Asian countries. The reason for this result may be the issues of incidence rate or racial characteristics, such as dense breast tissue. The results indicate that mammography screening should be adopted prudently in Asian countries and other countries with low incidence rates.

We suggest that cultural differences among nations should have a significant impact upon the exports of Korean broadcasting contents due to the fact that production and consumption of the contents are influenced by their own cultural aspects. Based on Hofstede's cultural dimensions frequently cited in the literature, we perform empirical analysis to identify the impact of cultural dimensions upon the export amounts by investigating four-year export data of Korean broadcasting industry. In our research model, Hofstede's cultural dimensions and GDP per capita are independent variables and a genre of broadcasting contents is used as a moderating variable. We find in our analysis that three cultural dimensions such as individualism, uncertainty avoidance, masculinity significantly affect the export amount but do not find the impact of power distance.

Studies on the relation between socio-economic factors and metermal and child health have found that poverty, lack of edcation, inappropriate health serives are affecting to maternal and child health. The Gender Related Development Index (GDI) focuses on equality between men and women as well as on the average achiement of all people taken together, using same cariables as the Human Development Index (HDI) which are life expectancy, literacy rate, and per capita GDP. This research is to inverstigate whether HDI and GDI are useful determinants for maternal infant mortality. Using 146 UN member countries date, we condented multiple regression analysis for maternal and infant mortality with three models which are Model(individual variables-literacy rate, per capita GDP), Model(HDI) and Model(GDI). The results showed that HDI and GDI are powerful determinants of both maternal and infant mortality, respectively HDI($\beta$=-1.18, t=3.3; $\beta$=1.04, t=5.1) GDI($\beta$=-1.44, t=3.9; $\beta$=1.28, t=6.5) The higher power in model with GDI for both maternal and infant mortalities represented that GDI was more powerful determinant of maternal and infant mortality, than HDI respectively HDI($R^2$=0.824, $R^2$=0.842), GDI($R^2$=0.834, $R^2$=0.865). In conclusion, the maternal and infant mortalities are explained by GDI than HDI and may be lower in the societies where there are less discimination between men and women.

This study was done through Panel Gravity Model to analyze the trade pattern of Korean motor industry and empirical analysis was also performed on the effect of regional economies joining to the Korean trade is to draw out some implications. Compared with per capita pattern regarding the income levels of both the countries, the results indicated that trade of Korean motor industry followed GDP pattern in accordance with the overall market. The results of effect on regional economic integration to Korean motor industry reflected 179% and 198% increase in motor trade industry and motor parts trade, respectively. To expand the trade of Korean motor industry at the international competitiveness level, focus should be made on smaller, smarter and greener car with lesser impact on the environment. Hence, the present investigation suggested that government should not delay in retaining the core technology as well as private sector should also aggressively invest in the market.
