In this paper, it is tried to combine the decomposition method and econometric analysis for the extension of the decomposition method. Since two approaches approach the energy efficiency problem in the different perspectives, it is believed that it is hard to reconcile the results of two approaches. In the results of energy intensity effect analysis with the econometric method, it is found that the increase in the energy price results in the improvement of energy intensity effect. In enconometric analysis of energy efficiency, the coefficient of a time trend measured as a proxy of energy efficiency is significant and has a negative effect on the energy consumption. This finding implies the energy efficiency improves very slowly over time. In addition, the directions of energy efficiency improvement in the decomposition method are consistent with those in the econometric analysis in four industries. This finding indicates that two methods may be in complementary cooperation for the analysis of energy efficiency. Therefore, it is needed the efforts to seek the complementarity between two methods for the enhancement of academic and policy implications.

In this study, we analyzed previous studies and collected important factors that can have an impact on the effectiveness of Cyber Home Learning. We were supposed to regard the effectiveness as an intention to attend the class. We selected the instructional value, website usability, subjective norms as factors that can have an impact to this intention. We conducted the survey based on these factors. We distributed and collected data from 6th grade elementary students in Kyungki Province. And also we performed confirmatory factor analysis. After modifying the survey, we gave it again to the students. Finally we were able to establish my research model and hypothesis. They are accepted through the result of the Analysis Structural Equation Modeling. Moreover, included in this study are the restrictions and suggestions.

This study aims to explore the effect of quality factors and customer involvement on users' intention to purchase in the live-commerce context. For this purpose, statistical methods such as reliability test, factor analysis, ANOVA, regression analysis were carried out using the survey data from live-commerce users. The quality factors of live-commerce were classified into contents, system, service, and show host characteristics, and customer involvement was analyzed by dividing it into product involvement and service involvement. The results showed that each quality factor of live-commerce had a significant positive effect on the intention to purchase. On the other hand, customer product involvement had a significant moderating effect on content and system quality, service involvement had a significant moderating effect on service and show host characteristics. The degree of each quality factor on intention to purchase was higher as customer involvement was higher. Theoretical and practical implications were drawn from these findings.

This study analyzed what the Servicescape factor of the student cafeteria in university is, whether food quality and price fairness show any mediating effect in relation between Servicescape factor and user satisfaction. First, analysis shows that Servicescape factors of cafeteria for university students are 'extensity', 'cleanness', 'aesthetic' and 'agreeableness'. Second, 'cleanness and 'aesthetic' factors are found to have positive(+) influences on user satisfaction. Third, 'cleanness', 'aesthetic' factors are found to have positive(+) influences on food quality. Fourth, 'cleanness' factors of food quality shows complete mediating effect in the influential relation between Servicescape factor and user satisfaction and 'aesthetic' factors shows partial mediating effect. Fifth, significant influence was not seen in all factors of price fairness by Servicescape factors of student cafeteria in university. Sixth, price fairness was found to play no mediating role in the influential relation between Servicescape factor and user satisfaction. This study will help understand the mediating effect of food quality and price fairness in the relation between the Servicescape of student cafeteria in university and user satisfaction.

아웃소싱 시장의 지속적인 성장에도 불구하고 국내 아웃소싱 시장은 대규모의 계약이 이루어 지지 않고 있다. 아웃소싱의 위험요인이 아웃소싱의 활성화에 장애요인이 될 수 있다. 정보시스템 아웃소싱의 위험요인에 대한 연구는 아웃소싱 수준 및 성과에 영향을 미치는 요소를 중심으로 연구가 진행되어 왔다. 즉, 전략적 효과, 경제적 효과, 기술적 효과와 같은 이익에 대한 연구가 주류를 이루고 있다. 그러나 아웃소싱 위험요인에 대한 연구는 사례가 거의 없고, 성과에 미치는 영향에 대한 실증적인 연구는 진행되지 않고 있다. 또한 아웃소싱 위험요소의 경우 대체로 발주자 입장에서 연구를 수행하고 있어, 실제 수주하고 있는 수주자의 입장에서 위험요소를 분석한 연구는 없는 상황이다. 본 연구는 기존 연구에서 제시된 아웃소싱 위험요소와 국내 정보기술 아웃소싱 상황에 맞는 위험요소를 도출하고, 이들 위험요소가 유발되는 정도가 정보기술 아웃소싱 성과와 어떠한 관계를 가지는지에 대해 실증적으로 연구를 수행하였다.

성장저해는 만성신부전 (chronic renal failure, CRF) 소아환자나 실험동물에게서 나타나는 합병증의 하나로, 그 발생기전이 잘 알려져 있지 않다. 성장저해를 일으키는 원인으로 비내분비적 요인 (metabolic acidosis, renal osteodystrophy, anemia)과 내분비적 요인의 복합적 결과로 생각하나, 비내분비적 요인들은 약물투여로 그 증세를 완화시켜도 성장저해에 대한 궁극적 치료효과는 나타나지 않는다. 따라서 성장 호르몬 (Growth Hormone, GH)이 관여하는 내분비적 요인의 변화에 그 병리기전이 있을 것으로 연구되어 왔다. GH는 직접적 성장 효과와 Insulin-like growth factor-1(IGF-I)을 간으로부터 유리시켜 나타나는 간접적 성장효과를 가지고 있다. 그런데 CRF환자의 GH 및 IGF-I 의 혈중 농도는 정상이거나, 흑은 오히려 증가상태에 있음에도 볼구하고 성장저해가 일어나는 것으로 보아, 환자의 말단기관 (end-organ)에 원인을 알 수 없는 저항성 (resistance)이 있다고 규정되어진다.

2012년 9월부터 건설현장 위험성평가는 안전관리 업무로 의무화되었으나, 해당 근로자가 사전위험성을 추정하고 대책을 수립하여 재해예방 활동으로 연계되기에는 위험성평가 작성부터 어려움이 있다. 위험성평가 운영시스템 구축을 통해 건설현장 근로자가 해당작업의 위험요인 및 안전대책을 쉽게 파악할 수 있도록, 작업 공종 선택만으로 해당작업의 다양한 위험요인과 안전대책을 제시하고, 해당 공종에서 발생한 재해사례를 보여줌으로써 동종 재해 재발방지 대책수립이 가능하도록 시스템을 구축하였다. 이러한 위험성평가 활동의 효과분석을 위해 H건설사의 운영평가에서, 위험성평가 운영시스템 구축 이후 건설현장 근로자가 위험성평가 활용에 쉽게 접근할 수 있고 해당공정의 위험요인 추정 및 위험예방 대책 수립이 가능하게 되었으며, 평가기간 동안 재해율 감소에도 영향이 있는 것으로 분석되었다.

This study has examined the relationship between entrepreneurial orientation(EO), dynamic capability(DC) and export performance of international new ventures(INVs). Also, the moderating effect of external environment factors(the hostility at domestic markets and the industrial dynamics) were analysed. Empirical analysis was performed on 101 INVs. It was conducted using the PLS(Partial Least Square). The result of empirical analysis showed that there is a positive relationship between EO, DC and export performance. The result of moderating effect showed that two external environment factors have positive moderating effect on the relationship between EO and DC. However, there was not moderating effect of external environment factors on the relationship between DC and export performance.

본 연구는 기업규모, 장부가치/시장가치 비율, 순이익/주가 비율, 현금흐름/주가 비율, 레버리지 등 기본적 변수를 사용하여 주식수익률에 유의적인 변수를 확인하고, 또한 Fama and French(1993) 등에 의해서 제시된 다요인모형(multi-factor model)이 한국주식시장에서 적용가능한 지를 살펴보았다. 이를 위하여 본 연구에서는 Fama and MacBeth(1973)의 횡단면회귀모형과 Black, Jensen, and Scholes (1972)의 시계열모형을 사용하였으며, 실증분석결과를 요약하면 다음과 같다. 먼저 횡단면분석결과에 의하면, 장부가치/시장가치 비율(BE/ME), 현금흐름/주가 비율(C/P) 등이 주식수익률의 횡단면적 차이를 설명할 수 있는 유의적인 변수로 나타났다. 그리고 통계적 의미에서는 1월효과가 존재한다고 보기 어려우나, 경제적 의미에서 1월효과가 존재하는 것으로 생각된다. 시계열분석결과에 의하면, 시장요인, 기업규모요인, 장부가치/시장가치요인(또는 현금흐름/주가요인) 등의 3요인에 의해서 국내 주식수익률의 공통적 변동을 잘 설명할 수 있다. 즉 국내 증권시장에서도 Fama and French(1993)의 3요인모형이 성립될 수 있는 것으로 판단된다.
