This study investigated the relationship between consumers' knowledge and risk perception towards purchase intention of organic food. The data were collected from a sample of 311 housewives in Seoul and Ulsan. A structural equation modelling technique was used to test the causal model. The results indicated that subjective knowledge was significantly associated with purchasing organic food. Objective knowledge, in contrast, was only indirectly associated with purchasing organic food, through increased subjective knowledge and risk perception towards purchasing organic food. Risk perception towards organic food had a direct positive and relatively strong relationship with purchasing organic food. Implications of the results and limitations of the study were discussed.

The purpose of this study was to examine the relationship between mothers' smartphone dependency(MSD) and their children's problem behavior and how children's smartphone dependency(CSD) mediates this relationship. A survey was conducted in the Seoul and Gyeonggi of 300 mothers having children from two to six years old. The results showed that MSD was directly related to both CSD and children's problem behavior, and in particular, had greater effects than CSD on children's problem behavior. CSD was found to mediate the relationship between MSD and children's problem behavior. The results suggest that mothers and their children should be provided with education on the proper usage of smartphone to prevent problem behavior in children, and that the development of preventive programs for smartphone addiction is needed.

The purpose of this study was to investigate the effect of organizational culture (group culture, development culture, rational culture, hierarchical culture) on job satisfaction based on the mediating effect of organizational trust on workers corporations. In particular, in the relationship between organizational culture and job satisfaction, the mediating effect of organizational trust was demonstrated, which varies by communication control variables. The results of the study of 8,615 workers in the manufacturing, financial, and non-financial industries in HCCP(Human Capital Corporate Panel) are as follows. First of all, the result of research showed that rational culture, group culture, development culture among organizational culture had a positive effect on job satisfaction. But, the hierarchical culture had a negative influence on job satisfaction. Second, rational culture, group culture, development culture among organization culture had a positive effect on organizational trust. But, hierarchical culture had a negative influence on organizational trust. Third, in the relationship between organizational culture and job satisfaction, the partial mediating effect of organizational trust was verified. In other words, although organizational culture directly affects job satisfaction, it indirectly affects job satisfaction through organizational trust. Fourth, it showed a significant moderating effect of communication between organization trust and job satisfaction. In other words, it was found that the group with high organizational trust in the relationship between organizational trust and job satisfaction had higher job satisfaction than the group without it. Finally, in the relationship between organizational culture and job satisfaction, the mediating effect of organizational trust was demonstrated, which varies by communication control variables. In other words, the indirect effect of organizational culture on job satisfaction through organizational trust is higher in the group with high communication capabilities. Through discussion and conclusion, the academic and practical implications, limitations, and research directions of this study were presented.

This paper is to analyse empirically using the data collected from Korea portal Naver's ad management system and show online ad platform may not be two-sided market. It is aim of this study to propose the appropriate approach to define the market, based on the empirical result. Here are two research questions to be reviewed. First, is there any consistency between business model of search advertising and definition of two-sided market which Rochet-Tirole proposed in 2006? Second, do indirect network externalities exist significantly in search advertising market? if so, this study is going to estimate the level of it through empirical measurement. Based on Luchetta's paper which suggested that google may be one-sided market, it performed the correlation & regression analysis to prove his suggestion. The result is that online search advertising costs increased by more than 50 won when advertisers increased by one unit. However, there was no significant correlation and regression between the search frequency and online search advertising cost. It means that there is little possibility to identify two-sidedness in online search advertising service(market) because of no(or little) indirect network externalities which are a necessary condition for two-sided market. This result has three implications, such as the availability to adapt traditional market definition tools to online search advertising market, the possibility enhancement to find the fundamental competition elements in defined market and promotion of the powers of persuasion in competitive market reality. It is significant that the gap between legal scholars including regulatory practitioners and economists can be overcome to some extent. who have shown the different perspective on the two-sided market.

This research aims to find out the existence of considerable induced effect that the conventional I-O model cannot. First, we construct an environmental Social Accounting Matrix for Korea by combining statistics on the Korean GDP and I-O with physical data on the fossil energy consumption and $CO_2$ emissions. The impacts of productive activities on fossil energy consumption and $CO_2$ emissions are evaluated by calculating the e-SAM multipliers. By applying decomposition technique further, we get direct, indirect, and induced effects of production activities by industry. The result of decomposing the e-SAM shows that while the direct effect of the electricity industry is large, its indirect effect is very small. In the case of the primary metal industry, both the direct and the indirect influence of this industry were very large. On the contrary, in case of the service industry, the induced effect of fossil energy consumption was as high as 50% of the gross effect. These results suggest that different energy policies should be established for different industries. Also, the findings show the e-SAM model is better than I-O model in analyzing implications of policies on energy use in the economy.

본고(本稿)에서는 1970년 이후 한국(韓國)의 사회간접자본투자정책(社會間接資本投資政策)이 지역간 균형발전(均衡發展)에서 담당한 역할과 그 투자현황(投資現況)을 분석하였다. 이론적 분석에 의하면 사회간접자본투자(社會間接資本投資)는 지역발전의 주요정책수단이 되고 있다. 그러나 1970~85년의 기간에 도로(道路), 통신(通信) 등 주요 사회간접자본(社會間接資本)의 지역간 격차는 현저히 감소되었음에도 불구하고 성장(成長)의 지역간(地域間) 불균형(不均衡)은 크게 개선되지 못하였다. 이는 사회간접자본(社會間接資本)의 지역격차 완화로 수도권(首都圈)을 중심으로 하는 성장지역(成長地域)의 입지여건(立地與件)의 비교우위성이 약화되었으나, 수도권지역(首都圈地域)의 입지적(立地的) 이점(利點)을 상쇄할 만한 투자환경(投資環境)이 지방에 조성되지 못하였기 때문이다. 따라서 실질적인 지역발전을 도모하기 위하여는 입지여건(立地與件)이 상대적으로 불리한 지방에 기업투자(企業投資)를 유인(誘引)할 수 있는 세제(稅制), 금융(金融) 및 행정절차상(行政節次上)의 지원책(支援策) 등을 강화하여 해당지역의 산업활동(産業活動)을 촉진할 수 있는 정책이 함께 추진되어야 한다. 또한 지역의 필요성에 부응하는 사회간접자본투자(社會間接資本投資)를 도모하기 위해서는 지역의 특수성과 주민의 여론을 반영하여 지방정부(地方政府)가 투자결정을 주도할 수 있도록 지방정부의 재정지출 재량권이 제고되어야 한다.

The aim of this study is to test the behavioral acceptance of adopting smart-media for special education teachers on the points of personal innovativeness and social influence with structural equation modeling(SEM). The corelation of factors such as personal innovativeness, social influence, performance expectancy and behavioral intention are significant. The results of SEM analysis show that the direct impact of social influence on performance expectancy and behavioral intention is significant. The indirect impact of social influence toward behavioral intention through performance expectancy is also significant. However, the personal innovativeness is not statistically significant factor affecting performance expectancy and behavioral intention.

This study analyzed the effects of ICT technical characteristics of agricultural industry on smart farm entrepreneurial intention by using smart farm effort expectation and smart farm acceptance intention as mediators for smart farm pre-founders. Sub-variables of the technical characteristics of agricultural industry ICT were classified into availability, economics, data convergence and scalability. 349 questionnaires collected from pre-founders living in the country were used for empirical analysis. SPSS v22.0 and Process macro v3.4 were used to analyze the data based on serial multiple mediation model. First, economics and scalability had a positive (+) effect on start-up intention. Second, availability, economics and scalability had a significant effect on effort expectation. Third, effort expectation had a significant positive effect on acceptance intention. Fourth, acceptance intention had a significant positive effect on start-up intention. Fifth, the indirect effects of economics on start-up intention were all significant through effort expectation, through acceptance intention and through both effort expectation and acceptance intention. Sixth, the indirect effect of data convergence on start-up intention was significant through acceptance intention. Seventh, the indirect effect of scalability on start-up intention was significant through effort expectation and through both effort expectation and acceptance intention. As a follow-up study, it is necessary to study for the mediating variables other than mediators introduced in the study or the moderated mediation analysis through the conditional process model in which the moderating variable is introduced.

The purpose of this study was to understand the comprehensive relationship among sense of coherence, clinical practice stress, and major satisfaction of students in the department of dental hygiene. From four local universities, departments of dental hygiene were selected: two departments represented a three-year curriculum system and two represented a four-year curriculum system. Data from the final questionnaires of 319 students were analyzed. Differences between variables were analyzed using t-tests and ANOVAs, and correlations were checked using Pearson's correlation coefficients. Path analysis was conducted to analyze the relationship among clinical practice stress, sense of coherence, and major satisfaction. The results indicated that clinical practice stress had a negative influential relationship with both sense of coherence, and major satisfaction. In addition, sense of coherence had a positive influential relationship with major satisfaction. The direct and indirect effects among factors displayed significant differences, indicating that clinical practice stress has a partial mediation effect on sense of coherence and major satisfaction. Therefore, major satisfaction can be increased by developing and implementing programs to improve sense of coherence.

The aim of this study is to examine the relationships between social support and child behavior problems and cognitive development in low income female-headed families. Informed by the stress-coping theory, family process model, and theoretical perspectives related to social support, this study estimates both direct and indirect effects of social support on child behavior problems and cognitive development. In particular, we focus on how the relationship between child outcomes and social support is mediated by mothers' parenting stress. The first three waves of longitudinal data from a subsample of 1,315 single and non-cohabiting low-income mothers in the Fragile Families and Child Wellbeing Study were utilized in this study. Results suggest that social support is directly associated with child behavior problems and also indirectly associated with child behavior problems mediated by mothers' parenting stress. Social support did not have a direct effect on children's cognitive development but rather had an indirect effect, which was mediated by mothers' parenting stress. The policy and practice implications of these findings are discussed.
