Purpose: Research and development of human capital in countries bring sustainable development to the nations. Especially for developing countries, the attraction of foreign direct investment not only brings economic growth to the country but also contributes to improving human capital. This study aims to assess the impact of foreign direct investment on human capital in ASEAN countries. Research design, data and methodology: With data collected from ASEAN countries from 1990 to 2019, panel data analysis is performed with revised model types (the Pooled OLS, Fixed effect model, Random effect model and regression with Driscoll-Kraay standard errors). Result: The results of the regression analysis show that FDI has a positive impact on human capital. At the same time, the study also found that public investment in education also positively affects human capital; the life expectancy factor does not affect human capital. Conclusions: With this research result, the authors also proposed a number of solutions to improve human capital by attracting FDI and improving the efficiency of investment for the education of ASEAN countries. Besides, public expenditure on education also plays an important role in raising human capital. Therefore, investment in education should be promoted further in the future.

Purpose: This study extends previous empirical work on the threshold effects of institutions on the relationship between infrastructure and economic growth. It does so by using three sub-indices of institutions as the threshold variable in place of aggregate index. This is with a view to determining the roles of the sub-indices in the nexus between infrastructure and economic growth. Research design, data and methodology: The analysis is based on a dynamic panel threshold regression model using a panel data set comprising 41 countries in Sub-Saharan Africa over the sample period of 1996-2015. Data are obtained from Ogbaro (2019). Results: The study finds that infrastructure exerts significant positive effects on economic growth below and above the threshold values of the three sub-indices, with higher effects above the threshold values. Results also show that on average, the Sub-Saharan African countries are not able to satisfy any of the threshold conditions, which accounts for their poor growth experience. Conclusion: The study concludes that countries with weak institutions do not benefit maximally from infrastructure development policies. The paper, therefore, recommends that countries in Sub-Saharan Africa need to focus on improving their institutional patterns if they are to reap the optimum benefits from their infrastructure development efforts.

본 논문은 환경쿠즈네츠곡선가설에 기반을 두고, 경제개발 수준과 기술혁신수준이 다른 전세계 88개 국가에 대한 패널데이터를 이용하여, 기술혁신이 이산화탄소배출량 변화에 미치는 영향을 분석하였다. 기술혁신이 온실가스배출량에 직접적으로 미치는 효과와 소득수준을 변화시켜 온실가스배출량에 미치는 간접적 효과를 종합해본 결과, 비록 미세하지만 기술혁신은 결과적으로 온실가스배출량을 증가시키는 것으로 나타났다. 그러나 패널데이터 모형은 각 '시점 내'에서 변수 간 효과를 분석하는 정태적 모형이라는 한계를 가지고 있다. 이를 개선하기 위해 본 논문에서 채용한 Panel VAR(Panel Vector Auto Regression)모형에서는 기술혁신수준이 시차를 두고 온실가스 배출량에 미치는 영향을 분석할 수 있다. 분석 결과 기술혁신(R&D 투자)과 같은 외생적 충격(Shock)이 일인당 온실가스 배출량 감축에 3년 정도의 시차를 두고 영향을 미치는 것으로 나타났다.

Objectives: We used the 2019 Korea Health Panel Annual Data to analyze factors related to visits to Korean medicine (KM) outpatient clinics among patients with mood disorders in Korea. Methods: Individuals aged 19 years or older, with depressive or bipolar disorders, and with a record of using Western medicine (WM) and/or the KM medical service were included. The 266 subjects were classified into the WM group or the integrative medicine (IM) group. The Andersen healthcare utilization model was used to analyze factors that potentially influenced the subjects' healthcare utilization. Binomial logistic regression analysis was used to analyze factors influencing the use of IM medical services. Results: Among the subjects, 75.56% (n=201) were in the WM group, and 24.44% (n=65) were in the IM group. Statistically significant differences were observed in residential areas, total annual income, the presence of disability, and the level of pain/discomfort between the two groups. Regression analysis found that residential areas and pain/discomfort were factors related to the use of IM services. Specifically, reporting "a lot" of pain/discomfort compared to "no" pain/discomfort showed a significant positive relationship with the use of IM (odds ratio=4.57, 95% confidence interval=1.79 to 11.70). Conclusions: This study was the first to analyze the status of KM medical service use and related factors among patients with mood disorders in Korea. The finding that the presence of pain/discomfort was positively correlated with the use of KM services is potentially related to medically unexplained physical symptoms or somatization phenomena.

5th Assessment Report of the Intergovernmental Panel on Climate Change Weather (AR5) predicts that recent severe hydrological events will affect the quality of water and increase water pollution. To analyze changes in water quality due to future climate change, input data (precipitation, average temperature, relative humidity, average wind speed, and solar radiation) were compiled into a representative concentration curve (RC), defined using 8.5. AR5 and future use are calculated based on land use. Semi-distributed emission model Calculate emissions for each target period. Meteorological factors affecting water quality (precipitation, temperature, and flow) were input into a multiple linear regression (MLR) model and an artificial neural network (ANN) to analyze the data. Extensive experimental studies of flow properties have been carried out. In addition, an Acoustic Doppler Velocity (ADV) device was used to monitor the flow of a large open channel connection in a wastewater treatment plant in Ho Chi Minh City. Observations were made along different streams at different locations and at different depths. Analysis of measurement data shows average speed profile, aspect ratio, vertical position Measure, and ratio the vertical to bottom distance for maximum speed and water depth. This result indicates that the transport effect of the compound was considered when preparing the hazard analysis.

본 연구는 한국프로야구리그(KBO)에서 활동하는 개별선수의 승리에 대한 기여도, 즉 생산성을 추정하는 모형의 구축을 목적으로 한다. 기존의 지표인 대체선수대비승수(WAR)의 단점인 계산방법의 복잡성을 해결하기 위하여 KBO 공식 홈페이지에서 제공하는 기록만을 이용한 계량모형을 구축함으로써 새로운 시즌의 기록만 대입하면 생산성을 생성할 수 있게 하였다. 또한, Scully(1974)와 Krautman(1999) 등 미국 메이저리그 선수의 가치추정모형이 소수의 기록에만 의존하였던 점을 개선하여 KBO가 발표하는 61개 기록을 모두 사용하여 현실에 적용할 수 있는 모형을 구축하였다. 2002-14년 팀기록의 패널 자료를 이용하여 득점 및 실점방정식을 추정하여 회귀분석에 기초한 대체선수대비승수를 추산하였다. 추정 결과, WAR과 상관계수가 타자는 0.869, 투수는 0.882로 나타나 두 지표가 비교적 유사한 것으로 나타났다. 추정 결과를 근거로 2014년 시즌 후 FA선수들의 계약 내용을 평가하면 비교적 생산성 추정치와 계약액수의 상관관계가 높아서 구단이 FA계약에서 합리적인 판단을 하고 있는 것으로 나타났다.

Purpose - In this article, a dynamic model like a VAR is an appropriate choice for estimating the possible interrelationship between ownership structure and firm performance as a dynamic process. Research design, data, and methodology - Data of this work are collected from Chinese stock exchange including 350 Chinese-listed firms during the period of 1999-2012. We hypothesize that this interrelationship dynamically exists between ownership structure and firm performance. To examine the correlation, a panel Vector Auto-regression (PVAR) approach generated by GMM method is utilized to test the possible dynamic relation embedded in corporate governance. Another two dynamic analysis solutions such as orthogonalized impulse-response function and variance decomposition are also used simultaneously. Results - Findings of this study indicate the evidence that dynamically endogenous relationship exists between ownership structure and firm performance. Further, there is a dynamical correlation between investment and performance. Impulse response and variance decomposition illustrate that impact of a shock to variables themselves is the main source for their variability. Conclusions - The conclusion in this study is that there is a bidirectional and inter-temporal effect between proportion of ownership and corporate performance for a long run in accordance with impulse response function. Overall, our results suggest that corporate governance in China is more market oriented.
