So far, the phenomenon of "electrification" has been deepened in Korean industry and especially direct heating energy which accounted for 44.0%(2010) of total energy consumed in Korean manufacturing has been significantly electrified. This paper decomposed electricity consumption for direct heating in Korean manufacturing from 1992 to 2012 using LMDI(Log Mean Divisia Index). This paper includes 4 different factors such as electricity proportion effect, direct heating proportion effect, energy intensity effect and added value effect. And this paper compared the consumption pattern by business type. As results, electricity proportion effect had contributed the most to the increase of electricity consumption for direct heating in Korean manufacturing. And Petrol-Chemical and Iron & Steel had the most electrification of direct heating.

This study aims to analyse whether outward foreign direct investment(FDI) by Korean manufacturers has a positive or negative effect on the nation's exports and imports. It provides a comprehensive analysis using both micro and macro approaches to overcome the limitations of the previous studies. In its micro-analysis, this study analyzed the impact of the outstanding outward FDI stock and other related factors on net export/import creation using panel data of 589 overseas affiliates of Korean manufacturers during the period of 2006 to 2011. And in the macro-analysis, the study analyzed the impact of outward FDI on exports using panel data of 23 manufacturing sectors during the period of 2000 to 2011. As a result of empirical study, contrary to the results of most previous studies, Korea's export can be negatively affected when it's manufacturing companies increase their outward FDI and localize their overseas businesses.

Estimate of heritabilities, genotypic and phenotypic correlations and path coefficient analysis were performed for the seven characters of barley cultivars (Hordeum vulgare L.). Heritabilities of broad sense for stem length and spike length were 0.923 and 0.907. Kernels per spike, grain yield and 100 grain weight also showed high heritabilities. High genotypic and phenotypic correlations existed between stem length and 100 grain weight. Grain yield showed highly significant phenotypic correlation with spike length, 100 grain weight and kernels per spike. Genotypic correlations between those characters were moderately high. Number of stem had greatest direct effect but the number of spike had a strong negative direct effect upon grain yield. Kernels per spike via number of spike showed greatest indirect effect and the number of stem via number of spike showed strong negative indirect effect upon grain yield.

The studies were intended to clarify the correlations between the characters and the influences upon yield of mulberry trees. The analysis of covariance was used to obtain the genotypic correlations and phenotypic correlations among the eight characters namely branch length, node number, branch diameter, branch number per stock, total branch weight, old branch weight, new shoot and leaf weight, etc., and path-coefficients were calculated by Dewey's method (5). The results obtained are summarized as follows： 1. Genotypic correlations were slightly higher than the corresponding phenotypic correlations between tile characters as shown in Table 1. It could be indicated that hight leaf yield was genetically correlated with almost all characters studied except branch diameter. 2. Leaf yield of mulberry trees was mainly associated with the characters such as node number per branch, total branch weight and old branch weight, etc. 3. Branch length, branch diameter, branch number per stock and new shoot weight had little direct influence upon yield but it had rather considerable indirect in fluence upon yield by increasing the node number and total branch weight per stock. As a result, it can be concluded that total branch weight is primarily determined by branch number per stock and old branch weight, and in turn the leaf yield of mulberry trees is secondary determined by the node number by increasing the branch diameter and length which are positively correlated with branch number per stock and new shoot weight of mulberry trees.

본 연구는 확장된 합리적 행동이론(ETRA)을 이용하여 주식투자 시 자본시장심리지수를 기반으로 한 어플리케이션의 선택행동에 영향을 끼치는 요인들과 투자자의 휴리스틱과의 관계를 알아보는데 있다. 연구자는 개별 투자자의 휴리스틱이 선택행동에 영향을 미칠 것으로 추정하고 대표성 휴리스틱, 가용성 휴리스틱, 감정 휴리스틱을 측정하여 선택행동에 영향을 미치는 매개변수로 분석을 하였다. 연구모델의 경로계수 분석결과는 다음과 같다. 첫째, 독립변수인 투자기회확장 그리고 매개변수인 휴리스틱 중 대표성 휴리스틱이 행동의도에 영향을 미치는 것으로 나타났다. 둘째, 행동의도가 종속변수인 선택행동에 영향을 미치고 매개변수인 가용성 휴리스틱이 선택행동에 영향을 미치는 것으로 나타났다. 연구모형에서 대표성 휴리스틱에 영향을 주는 독립변수는 혁신적 성향, 투자기회확장, 사용비용, 그리고 인지된 효익이며 반면에 가용성 휴리스틱에 영향을 주는 독립변수는 혁신적 성향과 투자기회확장으로 밝혀졌다. 매개효과 검증결과에 의하면 서비스다양성은 선택행동에 영향을 미치는데 휴리스틱의 매개효과가 없고 직접효과만 있는 것으로 밝혀졌다. 반면에 투자기회확장은 선택행동에 미치는 직접효과는 통계적으로 유의하지 않고 매개변수 휴리스틱의 간접효과 값이 0.217이고 통계적으로 유의하여 매개효과가 있는 것으로 밝혀졌다. 휴리스틱의 매개효과를 개별적으로 확인한 결과 첫째, 대표성 휴리스틱은 매개효과를 통한 간접효과가 없는 것으로 확인되었다. 둘째, 가용성 휴리스틱은 매개효과의 크기가 0.1360이고 경로계수가 통계적으로 유의하게 나타나 매개효과를 통한 간접효과가 있다는 것을 확인하였다. 따라서 독립변수 투자기회확장은 시장 심리지수를 기반으로 한 어플리케이션에 대한 선택행동에 영향을 미치는데 직접적으로 영향을 미치지 않고 투자자의 가용성 휴리스틱이 매개가 되어 간접적으로 선택행동에 영향을 나타내는 것을 실증적으로 확인하였다.

The study aims at verifying the effects of private donors' emotional or demonstrable utility on their mental health with the mediation effect of self-acceptance and the moderation effect of the gratitude for their lives. As a result of causal analysis of the variables by structural equation models, the notable findings are as follows: First, among the group of private donors with increased gratitude for their lives through sponsorship, while emotional utility from donative activity has a positive effect on donor's mental health, demonstrable utility does not have it. The indirect effect of self-acceptance is proved between emotional or demonstrable utilities and mental health. Second, among the donors without increased the gratitude, emotional utility has direct effect on donor's metal health but demonstrable utility does not affect the metal health. While the self-acceptance shows a full mediation effect between demonstrable utility and mental health, emotional utility has no mediation effect. In conclusion, the moderating effect of the gratitude for their lives is empirically proved and the donors who their gratitude for life has increased due to donative activity show better metal health, self-acceptance level, higher emotional and demonstrable utility, therefore, the gratitude for life is a key for metal health through donation.

This study was conducted to find a pathway from the general government debt to GDP ratio(GDR) to the age standardized Suicide Rate(suicide rate). The variables used in this study are GDR, the consumer price index for living necessaries(CPIL), the household debt to GDP ratio(Household Debt), and suicide rate. The data used in this study were standardized data from 2001 to 2015 of Korean Statistical Information Service(KOSIS) and the path analysis was performed using the analysis IBM SPSS 22 and Amos. As a result of the path analysis, the path of GDR-CPIL-Household Debt-Suicide rate, and the direct of effect were in order 0.954, 0.904 and 0.675 were confirmed. The indirect effect of GDR on Household Debt is 0.862, GDR on Sucide Rate is 0.581, CPIL on Suicide Rate is 0.610. Neither of these indirect effect coefficient was significant(p>0.05).

이 연구는 선거에서 후보자들의 정책 입장(issue stance)을 유권자들이 어떻게 판단하고 인식하는 지 살펴본다. 기존의 연구들은 후보자들의 정책에 대한 유권자들의 인식을 설명하는 데서 캠페인 정보(campaign information)의 직접적인 영향을 제대로 고려하지 않았다. 이 논문은 후보자 정책 입장에 대한 캠페인 정보가 과연 유권자들의 인식에 직접적인 영향을 미치는 지 미국에서 이루어진 실험 데이터를 이용하여 분석한다. 아울러 투영 효과(projection effect)나 허구적 일치성 효과(false consensus effect) 등 기존의 연구에서 제시된 설명들이 이러한 캠페인 정보의 영향을 감안했을 경우에도 여전히 유효한 지 살펴본다. 실험 데이터의 분석 결과는 캠페인 정보가 후보자 정책에 대한 유권자들의 판단에 직접적인 영향을 미치며, 이러한 캠페인 정보의 영향을 감안했을 때 투영 효과는 여전히 유효한 반면 허구적 일치성 효과는 상대적으로 약하게 나타난다는 것을 보여준다.

본 연구의 목적은 1992년부터 산업자원부에서 추진하고 있는 에너지절약기술개발사업의 2000년까지 상용화 과제에 대한 에너지절약효과 산정 및 사회적 비용산출이다. 기술 개발에 의한 에너지 절약효과는 개발된 제품의 사용에 의한 직접적인 절약효과와 기술축적 및 타 산업으로의 기술파급 등에 의한 절약효과 등 간접적인 효과로 나누어 볼 수 있겠으나 본 연구에서는 분석자료 및 시간적인 제약으로 인하여 이 중 개발품의 사용에 의한 직접적인 효과에 한정하여 에너지 절약효과를 측정하였다.(중략)
