Purpose - This study analyzed how image affects customer trust and satisfaction in the online shopping mall market, which is becoming more competitive; future implications for customer management in online shopping malls were presented. Consumers visit and prefer a few shopping mall sites instead of many sites. Consumers do not visit sites that cannot provide trust and satisfaction. Therefore, establishing trust and satisfaction with differentiated image is essential for survival and growth. Specifically analyzing company image, shop image, and brand image, I studied how symbolic image, functional image, and empirical image affect satisfaction mediated by trust in the online shopping malls of hypermarket retailers. Research design, data, and methodology - To investigate the relationship between image and satisfaction of big box retailers' shopping malls in the online market, the study is based on analyzed data from questionnaires involving advanced research. From May 1st to 20th in the year 2014, a questionnaire survey targeting university students using big box retailers' shopping malls in Seoul was conducted. A total of 282 questionnaires were conducted, and 276 questionnaires were used for empirical analysis, excluding invalid data. Using the SPSS 21.0 statistics package, factor analysis and regression analysis were implemented, and effects of image on trust and satisfaction were presented. Results - First, symbolic image can affect satisfaction with only trust. Among 3 image factors, symbolic image exerts the most influence on trust; trust is important in coupling the medium to satisfaction. Second, functional image and empirical image affect satisfaction directly and indirectly with trust. Conclusions - As I classified the image of hyper market retailers' online shopping malls into symbolic, functional, and empirical image, I analyzed the effects of image on trust and satisfaction empirically. The results of the study and strategic implications are as follows. First, symbolic image can affect satisfaction with only trust. Among 3 image factors, symbolic image exerts the most influence on trust; trust is important in coupling the medium to satisfaction. The establishment of a distinctive symbolic image, such as the online shopping mall's loyalty, level of awareness, and special service, is needed. With the establishment of symbolic image, trust and satisfaction could be improved. Second, functional image and empirical image affect satisfaction directly and indirectly with trust. Especially, as functional image affects trust more than empirical image, setting and implementing a strategy for empirical image based on the right price, service, and convenience could raise trust and satisfaction. Empirical image affects trust and satisfaction substantially. Even though empirical image's influence on trust is lower than that of other three image factors, empirical image's influence on satisfaction is higher than symbolic image. Therefore, it requires a strategy for providing joyful use, and information research functions and distinctive use experience are important to improve satisfaction. This study analyzed image characteristics of hyper-market retailers' online shopping malls in the fast-growing online market; future strategic implications were presented.

This study is conducted to determine the effects of dietary levels of corn and tuna oils on the formation of preneoplastic lesions in die-thylnitrosamine (DEN) induced rat hepatocarcinogenesis. Weanling male Sprague-Dawley rats were fed 2.5, 5, 15, 25% (w/w) corn or tuna oils. Hepatocellular carcinogenesis was induced by DEN (200 mg/kg body weight) and two-thirds partial hepactectomy was carried out 3 weeks later and were sacrificed 8 weeks after DEN initiation. Tuna oil group showed smaller area of placental glutathione S-transferase (GST-P) positive foci than com oil group. Com oil group of 25% (w/w) showed the widest area of GST -P positive foci, and tuna oil group showed significantly smaller area of GST-P positive foci than com oil in 25% (w/w) level but had no differences between oil levels. Thio-barbituric acid reactive substances (TBARS) content was the highest in 25% (w/w) level of tuna oil group fed long chain and highly polyunsaturated fatty acids. Also serum ${\gamma}$ -glutamyltranspeptidase (GGT) activities in 25% level of tuna oil group were significantly higher than by other levels. As oil contents increased, glucose 6-phosphatase (G6Pase) seems to decrease in com oil groups but remained the same in tuna oil groups. Glutathione reductase (GR) activities were significantly higher in tuna oil group, and the higher the level of tuna oil, the higher GR activities. But Cu/Zn superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities didn't seem to be influenced by levels and kind of dietary fats. Therefore, as oil levels increased, com oil rich in n-6 fatty acids promoted carcinogenesis but tuna oil rich in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) of n-3 fatty acids suppressed. Although lipid peroxidation products were elevated in 25% (w/w) tuna oil group, GST-P positive foci didn't increase. Therefore pre-neoplastic lesions might be reduced through mediation of a lipid peroxidation process in tuna oil. As fat contents of tuna oil increased, elevated GR activities may give a rise to produce more reduced glutathione in order to protect against free radical attack, and high G6Pase activities remained the same and they contributed to membrane stability. So tuna oil diet seems to protect hepatocarcinogenesis.

This study was conducted to determine the casual relationship among family support, social support, workplace spirituality, and quality of life (QOL) for middle-aged, male office workers, as well as the effects of family support, and social support on their QOL with the mediation of workplace spirituality. The participants were 288 middle-aged, male office workers, and the data were collected from 14 October to 30 November, 2016, through questionnaires. The data were analyzed with descriptive statistics and Pearson's correlations using PASW 21.0, while the AMOS 18.0 program was used for structural equation modeling (SEM), and the fitness of the final model was determined using RMSEA .05, GFI .98, AGFI .94 and NFI .96. The results of this study can be summarized as follows. There were correlations between family support, social support, workplace spirituality, and QOL for the middle-aged, male office workers. Second, family support (${\beta}=.60$, p<.001) and social support (${\beta}=.47$, p<.001) had a direct effect on their workplace spirituality. Third, family support had direct (${\beta}=.12$, p=.002) and indirect (${\beta}=.10$, p<.001), while social support also had direct (${\beta}=.12$, p<.001) and indirect (${\beta}=.08$, p<.001) effects on their QOL. The findings also suggested that workplace spirituality had a partial mediating effect between the family support, social support, and QOL of the middle-aged, male office workers.

Recently, the government has been spending a large amount of money to support start-ups with its major policies aimed at economic growth and job creation under the keynote of innovative growth. Nevertheless, the Global Entrepreneurship Development Institute (GEDI) gave a very low assessment of the social and cultural support areas of Korea's start-up ecosystem in the 2018 Global Entrepreneurship Index (GEI), indicating that unlike the government's interest, our perception of start-ups has not been positive. This study surveyed 300 prospective entrepreneurs and entrepreneurs. In addition, this study empirically analyzes how social support of those around them is related to their entrepreneurial intentions and behaviors. As a result, it was not possible to confirm whether social support affects entrepreneurial intentions, but social support had positive influences on entrepreneurial behaviors. In addition, social support was found to have positive influences on entrepreneurial behaviors with dual mediation of entrepreneurial self-dfficacy and entrepreneurial intentions. Therefore, it was confirmed that social support is a factor that influences entrepreneurial behaviors and that entrepreneurial self-efficacy has important parametric effects. The findings of this study suggest that the government and entrepreneurship support agencies need to reflect programs in start-up support poject to promote social support for start-ups and to enhance entrepreneurial self-efficacy.

Purpose: This study was to observe the effects of music therapy on the cognitive function, behavior, and emotions of elderly dementia patients, and to seek musical mediation for them. This study was conducted with patients in the Dementia Sanitarium in C City from March 13 to April 17. Method: The design of research was a nonequivalent control group non-synchronized design and the subjects were 25 patients-15 of whom were in the experimental group with 10 in the control group. The music therapy consisted of favorite music listening in the morning, favorite music group singing activity after lunch, and relaxing music listening after dinner. The schedule was followed 6 days a week for 2 weeks for a total of thirty-six session. The effect of music therapy was measured by MMSE-K and the behavior and emotion measuring equipment which had been derived by the researcher. The verification of the effects is that the score of cognitive function, behavior, and emotions of the experimental and the control group which were measured after the therapy had been applied was analyzed by descriptive statistics and t - test using SPSS WIN program. Result: 1) The degree of cognitive function of the experimental group which was received the music therapy is $11.53{\pm}5.37$ which is a little higher than the control group which is $11.20{\pm}6.32$, but it is not significant statistically (t= .14, p= .887). The first hypothesis which had assumed the recepients would have had a higher cognitive function level than the other was rejected. 2) Behavior score of the experimental group that received the music therapy is $68.90{\pm}7.86$ which is higher than the control group which is $66.40{\pm}11.13$, but it is not significant statistically(t= .61, p= .548). The second hypothesis which had assumed the recepients would have had a higher behavior level than the other was rejected. 3) Emotions score of the experimental group that received the music therapy is $42.13{\pm}5.04$ which is higher than the control group which is $35.20{\pm}6.12$, and it is significant statistically(t=3..09, p= .009). The third hypothesis which assumed the recepients would have had a higher emotion level was supported. Conclusion: music therapy which is composed of listening to music and group singing activity is an effective strategy for improvement of the emotions of the dementia elderly. But, the effect of music therapy on the cognitive function and behavior of elderly dementia patients is not significant statistically.

The general aspects for the future warfare shows that the concept of firepower and maneuver centric warfare has been replacing with that of information and knowledge centric warfare. Thus, some developed countries are now trying to establish the information systems to perform intelligent warfare and innovate defense operations. The C4I(Command, Control, Communication, Computers and Intelligence for the Warrior) systems make it possible to do modern and systematic war operations. The basic idea of this study is to investigate how TAM(Technology Acceptance Model) can explain the acceptance behavior in military organizations. Because TAM is inadequate in explaining the acceptance processes forcomplex technologies and strict organizations, a revised research model based upon TAM was developed in order to assess the usage of the C4I system. The purpose of this study is to investigate factors affecting the usage of C4I in the Korean Army. The research model, based upon TAM, was extended through a belief construct such as self-efficacy as one of mediating variables. The self-efficacy has been used as a mediating variable for technology acceptance, and the variable was included in the research model. The external variables were selected on the basis of previous research. The external variables can be classified into following: 1) technological, 2) organizational, and 3) environmental factors on the basis of TOE(Technology-Organization-Environment) framework. The technological factor includes the information quality and the task-technology fitness. The organizational factor includes the influence of senior colleagues. The environmental factor includes the education/train data. The external variables are considered very important for explaining the behavior patterns of information technology or systems. A structured questionnaire was developed and administrated to those who were using the C4I system. Total 329 data were used for statistical data analyses. A confirmatory factor analysis and structured equation model were used as main statistical methods. Model fitness Indexes for measurement and structured models were verified before all 18 hypotheses were tested. This study shows that the perceived usefulness and the self-efficacy played their roles more than the perceived ease of use did in TAM. In military organizations, the perceived usefulness showed its mediating effects between external variables and dependent variable, but the perceived ease of use did not. These results imply that the perceived usefulness can explain the acceptance processes better than the perceived ease of use in the army. The self-efficacy was also used as one of the three mediating variables, and showed its mediating effects in explaining the acceptance processes. Such results also show that the self-efficacy can be selected as one possible belief construct in TAM. The perceived usefulness was influenced by such factors as senior colleagues, the information quality, and the task-technology fitness. The self-efficacy was affected by education/train and task-technology fitness. The actual usage of C4I was influenced not by the perceived ease of use but by the perceived usefulness and selfefficacy. This study suggests the followings: (1) An extended TAM can be applied to such strict organizations as the army; (2) Three mediation variables are included in the research model and tested at real situations; and (3) Several other implications are discussed.

The objective of this study is to verify the effects among communication between child-caring teachers and parents, teacher's burn-out and efficacy. An object of the study was totally 165 child-caring teachers, and the questionnaires survey results were used for statistical analysis by using questionnaires for survey constructed by Likert 5 point scale as a measuring scale. Collected data was statistically analyzed with SPSS 18.0 and AMOS 18.0 statistical program, and the statistical significance was verified with a significant level of 5%. The main results were withdrawn as follows. First, the communication between child-caring teachers and parents has a negatively significant effect on the child-caring teacher's burn-out. Second, the child-caring teacher's burn-out has a negatively significant effect on child-caring teacher's efficacy. Third, the communication between child-caring teachers and parents has a positively significant effect on child-caring teacher's efficacy. Fourth, the child-caring teacher's burn-out has a significant mediation effect between the communication and the teacher's efficacy. These results implies the importance of the communication between child-caring teachers and parents in order to decrease teacher's burn-out which is negative factor for teacher's efficacy.

The main purpose of this study was to empirically investigate the effects of participation behavior and performance improvement on motivation factors of Korean university students which participated in LINC by utilizing Vroom's Expectancy Theory. Three motivation factors of valence, instrumentality, and expectancy were examined in this study. In addition, two different models (valence and force model) analyzed the causal relationships regarding participation behavior and performance improvement. 236 data were collected and findings of this study were as follows: First, comparative analysis between demographic characteristics including university, major, and residence had no significant differences in mean value. However, females had higher levels of recognition related to valence (attractiveness) relative to males. Second, valence and the force model were significant predictors of LINC participation behavior and performance improvement. Furthermore, the coefficient of determination and beta coefficient of the force model were higher compared with the valence model. Third, the level of mediation effects including direct, indirect, and total effect of the force model was higher than the valence model. LINC participation behavior had a partial mediating effect between the three motivation factors and performance improvement variable.

This study examined the effect of cognitive reserve on the cognitive function in adults. In addition, this study investigated the direct and indirect effects of factors, such as subjective memory decline, depression, and quality of life on the cognitive function. The participants consisted of 253 adults who were 40 to 80 years of age. The assessment tools included the cognitive function scale, depression scale, quality of life scale, subjective memory decline, and cognitive reserve scale. The data results were analyzed using SPSS 25.0, and PROCESS macro for SPSS Version 3.3 and bootstrapping were used. The results of multiple mediating of the cognitive reserve and cognitive function in adults did not have a mediating effect in depression and subjective memory decline, and the quality of life showed a complete mediating effect in the relationship between the cognitive reserve and subjective cognitive function. Based on the results of this study, adults must accumulate cognitive reserve continuously through various activities and continuous training so that the cognitive function can lead to a positive direction. Nevertheless, more studies on cognitive reserve and cognitive function in healthy adults are needed.
