본 연구는 한국의 대 중국 제조업 직접투자(1996~2012)의 투자결정 요인을 4개 투자지역으로 구분하고 선행연구와 차별적으로 공간패널효과 모형을 이용하여 규명하였다. 연구결과 중국 전체를 대상으로 한 경우 1인당 RGDP가 정(+)의 유의적 변수로 나타났고 공간효과 변수도 매우 민감한 것으로 나타났다. A지역(동북지구 화북지구)은 1인당 RGDP가 정(+)의 유의적 변수, 공간효과 변수는 부(-)의 유의적 변수로 나타나 지역 내 투자는 대체적인 것으로 나타났다. B지역(화동지구 화남지구)에서는 1인당 RGDP가 정(+)의 유의적 변수, 공간오차모형 계수는 정(+)의 유의적 관계로 나타나 지역 내 투자는 보완적인 것으로 추정된다. C지역(중부내륙지구)의 분석결과 1인당 RGDP와 공간효과 변수 등 모든 변수는 비유의적이고 D지역(서북 서남지구)에서는 1인당 RGDP, WAGE(임금), ROAD(교통인프라), 공간효과 변수(${\rho}$, ${\lambda}$) 모두 정(+)의 유의적인 변수로 나타났다. 이는 한국의 대 중국 직접투자가 동부연안 중심에서 서북 서남지구로 전환을 모색하고 있는 것으로 추정되어지며 이 지역으로 진출시 인접 성(省)의 지역 환경적 특성을 충분히 고려할 필요가 있다고 하겠다.

Purpose The purpose of this study is to attempt to incorporate power theory to evaluate information capability of SCM adopters. Therefore, this study focuses on the relationship of information sharing, partnership quality, and information capacity according to the power intensity of the variables of SCM. and CSV value creation. Design/methodology/approach The questionnaire of SCM builder was conducted and 302 samples were analyzed. Based on the theoretical background of power and information capacity, we set up a structural equation model. Hypothesis testing and statistical analysis were done through AMOS and SPSS. Findings First, it shows that the compensation power among the constrained power has a positive effect on the partnership quality, and the legitimacy power has the positive influence only on the information sharing. Compulsive power, compensation, and legitimacy, which are generally restrictive powers, may reduce the quality of information sharing and partnership, but the results of this study are rather higher. Second, both non-binding power expertise and criterion have a positive effect on information sharing and partnership quality. Third, information sharing has a positive effect on partnership quality. Supporting a number of research results, it is well reflected in SCM attributes where interdependence is important. Fourth, information sharing and partnership quality have a positive effect on information capacity. Information literacy has become an essential element in modern management. Fifth, the enhancement of CSV value creation plays a role of a controlling variable to further strengthen information sharing through non - binding power attribute, expertise and conformity. In addition, the strengthening of CSV value creation has been shown to play a role as a controlling variable to further strengthen the quality of partnership through the non-binding power attribution, but expertise has been rejected.

Objectives: To determine the impact of cigarette prices on the decision to initiate and quit smoking by taking into account the interdependence of smoking and other behavioral risk factors. Methods: The study population consisted of 3,000 male Koreans aged ${\ge}20$. A survey by telephone interview was undertaken to collect information on cigarette price, smoking and other behavioral risk factors. A two-part model was used to examine separately the effect of price on the decision to be a smoker, and on the amount of cigarettes smoked. Results: The overall price elasticity of cigarettes was estimated at -0.66, with a price elasticity of -0.02 for smoking participation and -0.64 for the amount of cigarettes consumed by smokers. The inclusion of other behavioral risk factors reduced the estimated price elasticity for smoking participation substantially, but had no effect on the conditional price elasticity for the quantity of cigarettes smoked. Conclusions: From the public health and financial perspectives, an increase in cigarette price would significantly reduce smoking prevalence as well as cigarette consumption by smokers in Korea.

Purpose: The present study is a descriptive cross-sectional study of cause-and-effect relationship, which used the $7^{th}$ year data of the Panel Study on Korean Children, to investigate the effects of parenting stress, depression, and family interactions of the parents of early school-age children on children's subjective happiness. Methods: The present study included data of 1419 pairs of parents who participated in the mother and father survey of the Panel Study on Korean Children. The effects of parenting stress, depression, and parental family interactions on children's subjective happiness were analyzed as actor and partner effects using path analysis. Results: Parenting stress had an actor effect on depression; maternal parenting stress (${\beta}=-.21$, p<.001) and depression (${\beta}=-.30$, p<.001) had an actor effect on maternal family interaction; and paternal parenting stress (${\beta}=-.18$, p<.001) and depression (${\beta}=-.17$, p<.001) had a partner effect on maternal family interaction. Paternal parenting stress was found to have an actor effect on paternal family interaction (${\beta}=-.30$, p<.001), and parental depression was found to have actor effect (${\beta}=-.23$, p<.001) and maternal depression had a partner effect on paternal family interactions (${\beta}=-.22$, p<.001). Children's subjective happiness was found to have a statistically significant relationship with maternal family interaction (${\beta}=.40$, p<.001). Conclusion: The significance of the study is in its provision of basic data for adjusting parents' family interactions that are closely related to the growth and development of children by confirming the effect of parents' parenting stress, depression, and family interaction on children's subjective happiness.

The development of regulatory systems varies between transition and non-transition economies. This suggests that they provide different incentives for entrepreneurial development and could have varied effects on the economy because they have different methods to deal with market failure. However, limited empirical evidence exists to prove the assumption of dichotomy. Using comprehensive data for institutional quality, labor market and financial market development, this research sought to analyze their effect on employment growth at micro level. The results show that the quality of institutions in transition economies are poorer relative to those in non-transition economies, but their financial and labor markets are more developed than the latter. Further analysis for the transition sample shows that the three variables are individually positively related with employment growth. For the non-transition sample, institutional quality and labor market flexibility bear a positive and significant effect on employment. Financial market development enters the model with a negative coefficient when regressed alone, but a joint test of significance finds that all the variables have a positive effect on employment growth. This result could imply that there is interdependence between institutional quality, labor flexibility and financial market development in firm-employment-growth relationship, or complementarity between regulations and the quality of institutions. Alternatively, this finding suggests that a stringently regulated credit market in non-transition economies have a selection effect-allocating credit only to entrepreneurs who already demonstrate strong growth potential. In sum, despite differences in the evolution of regulatory environment between the two samples, both of them complement employment growth at firm level. The overall implication of these findings is that less rigid regulations and coherent policies that are enforced with impartiality provide incentives for firms to expand.

Recent researches on adipocytes in human and mice model have reported that the adipocytes are not only the fat depots but having role in maintenance of physiology and metabolism through adipokines released by them in accordance to their anatomical location. Ayurveda scholars too have mentioned different tissues like Vasa (inter muscular fat), Meda (visceral fat) and Majja (bone marrow) which are predominantly rich in adipocytes similar to adipose tissues, with a different sites, functions, compositions and pathological outcomes. The metabolic effect of Meda and Majja Dhatu on other tissues like muscle (Mamsa Dhatu), bone (Asthi Dhatu) and reproductive tissue (Shukra Dhatu) shows their functional interdependence. The detailed description of therapeutic indications of Vasa and Majja under Snehakarma (oleation therapy) illustrates that clinical physiology of these tissues have been elaborated rather than general physiology. This article is an attempt to comprehend the physiological aspect of Vasa, Meda and Majja retrospectively on the basis of their therapeutic indication for the management of variety of disorders, in the form of Sneha through different therapeutic procedures. An effort has been also taken to distinguish Vasa, Meda, Majja based on the functional peculiarities of adipocytes present in different sites of body like omentum, muscle and bone marrow. Critical observation of explanations of Vasa, Meda and Majja in Ayurveda compendia and advanced research in field of adipocytes reflected that Ayurveda scholars had deep insights regarding the various dimensions of adipocytes, most of which are in consistent with the advanced physiology and biomolecular studies of adipocytes.
