Purpose: This study was done to identify the relationship between transformational leadership by head nurses and positive psychological capital, psychological well-being, stress and somatization of staff nurses. Method: Participants in this study were 300 staff nurses in general hospitals located in G and B cities. Data were collected using self-administered questionnaires and analyzed using SPSS Win 18.0 program. Result: The major findings were as follows; 1) There were positive influences of transformational leadership on positive psychological capital, psychological well-being, and a negative effect on stress. 2) Positive psychological capital had a positive influence on psychological well-being, and negative effects on stress and somatization. 3) In the analysis of the mediating role of the positive psychological capital, transformational leadership was shown to indirectly affect psychological well-being and stress through positive psychological capital. Conclusions: These findings suggest that transformational leadership has important influences on employees' psychological well-being and stress via employees' positive psychological capital. To enhance psychological well-being and reduce stress for nurses, it is important to develop not only the leadership of head nurses but also the positive psychological capital of staff nurses.

With a series of unexpected huge losses in the financial markets around the world recently, especially in the insurance market with extreme loss cases such as catastrophes, there is an increasing demand for risk management for extreme loss exposures due to high unpredictability of those risks. For extreme risk management, to make a maximum use of the information concerning the tail part of a loss distribution, EVT(Extreme Value Theory) modelling nay be the best to analyze extreme values. The Extreme Value Theory is widely used in practice and, especially in financal markets, EVT modelling is getting popular to analyBe the effects of extreme risks. This study is to review the significance of the Extreme Value Theory in risk management and, focusing on analyzing insurer's risk capital, extreme risk is measured using the real fire loss data and insurer's specific amount of risk capital is figured out to buffer the extreme risk.

This paper examines whether the TFP growth of the Korean economy slowed down in 2000s based on growth accounting, focusing on how sensitive the results are to the particular aspects of the growth accounting method. There has been no consensus on this issue as the previous studies have provided very diverse results due to the differences in the details of the growth accounting method. Main results of this paper are as follows. First, it is how to calculate the labor income of the self-employed that has the most significant impacts on the estimated TFP growth. Measuring capital stock also matters. Second, the TFP growth of the Korean economy appears to be sustained in 2000s when the extreme assumptions on the labor income of the self-employed are excluded and capital stock is measured by the most frequently-adopted method in the previous studies. For more reliable estimation of the TFP growth, further studies on measuring the labor income of the self-employed are needed.

This paper is to estimate the total factor productivity(TFP) in the Korean manufacturing and service industries during the period 1975:1-2016:4 using the stochastic frontier analysis model. In order to analyze the determinants for the total factor productivity the paper estimates the industry-specific determinant elasticities of TFP using the autoregressive distributed model. The industry-specific determinants, which reflect the industrial structure and properties include markup, the ratio of capital to labor(KL), and the ratio of foreign intermediate goods (FIG) to industrial output. The average value for total factor productivity growth was estimated to be 0.0199 in manufacturing and 0.0063 in the service industry. The markup and KL elasticities of TFP were estimated to be 2.481 and 0.651 in manufacturing respectively and -1.403 and 0.042 in the service industry respectively. The empirical results suggest that the industrial markup and the ratio of capital to labor have had decisive effects on the changes in the total factor productivity in the Korean manufacturing and service industries during the period 1975:1-2016:4.

Since the financial crisis of 2008, the People's Republic of China has aggressively been pursuing the internationalization of the Chinese Yuan or Renminbi. In this regard, rapidly increasing use of the Chinese Yuan in the onshore and offshore markets are important milestones. This paper analyzes relationship between the onshore and offshore Chinese Yuan spot markets. Major findings of this paper are as follows : First, there is full feedback relationship between the Onshore and Offshore Chinese Yuan Markets. Second, the difference between the yuan's offshore exchange rate and the onshore was getting tight. Third, the offshore Yuan market affects on the onshore market based on the empirical tests.

As supreme technologies continue to be developed, industries such as artificial intelligence, biotechnology, robots, aerospace, electric vehicles, and solar energy are created, and the macro business environment is rapidly changing. Due to these large-scale changes and increased complexity, it is necessary to pay attention to the effect of social capital, which can create new value by utilizing capital increasing the importance of relationships rather than technology or asset ownership itself at the level of start-up strategy. Social capital is a concept first proposed by Hanifan in 1916, and refers to the overall sum of capabilities or resources that are latent or available for use in mutual, continuous, organic relationships or accumulated human relationship networks between individuals or social members. In addition, the diversity of start-up teams with diverse backgrounds, characteristics, and capabilities, rather than one exceptional founder, has been emphasized. Founding team diversity refers to the diversity of in-depth factors such as demographic factors, beliefs, and values of the founding team. In addition, changes in the macro environment are emphasizing the importance of technology start-ups and laboratory start-ups that lead industrial innovation and create the nation's core growth engines. This study focused on the I-Corps' program. I-Corps, which means innovation corps, is a laboratory startup program launched by the National Research Foundation (NSF) in 2011 to encourage entrepreneurship and commercialization of research results. It focuses on forming a startup team involving professors, researchers and market discovery activities. Taking these characteristics into account, this study empirically verified the impact of social capital from a network perspective and founding team diversity on I-Corps start-up performance. As a result of the analysis, the educational diversity of the founding team had a negative (-) effect on the financial performance of the founding team. On the other side, the gender diversity and the cognitive dimension of social capital had a positive (+) effect on the financial performance of the founding team. This study is expected to provide more useful theoretical and practical implications regarding the diversity, social capital, and performance interpretation of the I-Corps Lab startup team.

새로운 경영 패러다잉의 전환과 지식경제시대에 도래하고 있는 현재, 기업들은 기업의 생존을 위한 경영방식의 일환으로 지식경영을 도입하고 있다. 지식경영은 지식의 창조, 공유 및 활용을 포함한 개념으로서, 지식의 효율적인 공유 및 활용을 위해 지식경영을 응용한 지식관리시스템이 활발히 도입 중에 있다. 본 논문의 목적은 지식관리시스템의 도입현황(배경, 도입내용, 효과)의 사례률 비교, 분석하여 도입관련 시사점을 제시한다. 지식관리시스템의 배경은 지식공유를 통하여 핵심역량을 강화하고, 경영목표를 달성하기 위해 지식을 통합, 광리할 필요성으로 도입하였고, 도입 내용은 조직의 산재된 지식을 통합, 분류하여 지식데이터베이스를 구촉하였고 지식경영 중심의 기업문화률 이루고, 평가와 보상 체제를 구축하였다. 지식관리시스템의 도입 효과는 지식이 차별화 된 경쟁도구로 인식되면서, 개인의 지식이 조직의 지식으로 전환되면서 지식의 자본화가 이루어졌고, 조직구성원들의 업무효율성 또한 증대되었다. 사례분석결과 성공적인 지식경영을 위해, 지식경영을 위한 가치관 및 기업문화를 정착하고 기업특성에 맞는 방식을 고안해 지식경영을 실천하고, 파일럿 프로젝트를 실행한 후 단계적으로 확산해야한다는 것을 알 수 있었다. 또한, 전략적, 문화적, 조직적, 기술적 측면의 구체적인 시사점이 제시되었다.

본 연구는 기존의 특성가격기법(特性價格技法)(hedonic price technique)에 공간(空間)개념을 도입한 계량경제모형을 이용하여 분석하였다. 이 공간시차모형은 기존의 모형과 달리 특성변수의 변화에 따른 직(直) 간접효과(間接效果)를 동시에 포착할 수 있는 장점을 가지고 있다. 또한 공간시차모형의 회귀진단 및 가설검정 결과는 공간시차모형이 적합한 것으로 나타났다. 이 경우 공간시차를 고려하지 않은 OLS 회귀분석 결과의 계수들은 편기추정(biased)된 동시에 효율적(efficiency)이지 못하다는 것이다. 회귀분석 결과는 주택에 자본화된 대기오염에 대한 잠재가격(潛在價格)(marginal implicit price)은 주택평균가격의 약 1.5% 정도인 것으로 추정된다.
