This study is to reveal the acceptance factors of the Market Sentiment Index (MSI) created by reflecting the investor sentiment extracted by processing unstructured big data. The research model was established by exploring exogenous variables based on the rational behavior theory and applying the Technology Acceptance Model (TAM). The acceptance of MSI provided to investors in the stock market was found to be influenced by the exogenous variables presented in this study. The results of causal analysis are as follows. First, self-efficacy, investment opportunities, Innovativeness, and perceived cost significantly affect perceived ease of use. Second, Diversity of services and perceived benefits have a statistically significant impact on perceived usefulness. Third, Perceived ease of use and perceived usefulness have a statistically significant effect on attitude to use. Fourth, Attitude to use statistically significantly influences the intention to use, and the investment opportunities as an independent variable affects the intention to use. Fifth, the intention to use statistically significantly affects the final dependent variable, the intention to use continuously. The mediating effect between the independent and dependent variables of the research model is as follows. First, The indirect effect on the causal route from diversity of services to continuous use intention was 0.1491, which was statistically significant at the significance level of 1%. Second, The indirect effect on the causal route from perceived benefit to continuous use intention was 0.1281, which was statistically significant at the significance level of 1%. The results of the multi-group analysis are as follows. First, for groups with and without stock investment experience, multi-group analysis was not possible because the measurement uniformity between the two groups was not secured. Second, the analysis result of the difference in the effect of independent variables of male and female groups on the intention to use continuously, where measurement uniformity was secured between the two groups, In the causal route from usage attitude to usage intention, women are higher than men. And in the causal route from use intention to continuous use intention, males were very high and showed statistically significant difference at significance level 5%.

This study estimated the causal relationship among leisure identity salience (LIS), leisure constraints negotiation (LCN), and intentions to participate in leisure activity (IPLA). For this, we estimated structural equation models controlled by leisure constraints, and we used data collected from 296 college students residing in Seoul and Kyoung-gi providence. The following was obtained. First, for both groups with high and low levels of leisure constraints, LIS positively caused LCN, and this became more evident for the group with high level of leisure constraint. Second, for the group with low level of leisure constraints, LIS positively and directly caused IPLA, whereas this causal relationship could not observed from the group with high level of leisure constraints. Nevertheless, it indirectly and positively caused IPLA though LCN for the same group. This implies that the mediative role of LCN became more important as the level of leisure constraints became more restrictive. Further, we separately showed that the role of LIS was important in the process of LCN.

The study aims to estimate the determinants of policyholder's trust for the Chinese insurance industry by structural equation model. In particular, differences in determinants of trust among Chinese life insurance and auto insurance were derived from the latent mean and multi group analysis. The result shows the most effective determinants of trust were honesty, followed by credibility which shows the compensation ability of insurance company. However, benevolence is not influence statistically on the determinants of trust of both life insurance and auto insurance. Moreover, the policyholder's trust for the insurance industry was later extended to relationship commitment such as renewal and recommendation intentions. Especially, the linkage between the level of trust and relationship commitment was the strongest in life insurance than auto insurance. Even though the result is differ based on types of insurance, in order for the insurance industry to grow stably it is importance to get trust from policyholder.

The purpose of the present study is to examine how visitors of personal web sites evaluate self presentation styles. We hypothesized that visitors' gender, self construals, and self esteem would influence the evaluation (likeability and perceived competence) of the self presentation styles (bragging or positive presentation). The hypothesized models were tested with structural equation modeling. Gender differences among the constructs were also examined through latent mean analysis. The results revealed that females tended to have higher interdependent self construal than males. And the male and the female students showed higher likeability toward the self presentations of the other gender. Regarding perceived competence, women and men perceived the other gender more competent, and especially, women perceived men's bragging presentation more competent. Self construals and self esteem, however, did not show any significant effects, which were inconsistent with the results of the previous studies conducted with offline self presentation styles. One of the main implications of this study is that visitors' gender, among other things, is the most infueltial factor in perceiving and evaluating others' self presentation through personal web sites.

The purpose of this study is to suggest the policy direction for promoting Korean grape, Shine Muscat, export to China. For this, the data were collected from 102 Chinese who live in Guangzhou province. The survey was conducted from Oct 10th to 13th 2017. PLS-SEM model is used to investigate the main factors that cause the Chinese consumers to purchase Korean grape, Shine Muscat. This study finds that the post-evaluation factor is more important to obtain final evaluation and to purchase Korean grape in the future. Thus farmers and research institutes should investigate how to improve the quality for the sweetness and the texture of the grape, reflecting the Chinese consumers' preference.

By viewing donors for social welfare organization as both givers and beneficiaries, this study aims to address the correlations between the continuity of donors' contributions and enhanced sense of satisfaction as a consequence of participating in donation activities. The predominant concern of this study centers on: (1) the direct effects of individuals' emotional utility, demonstrable utility, trust toward donee organization, self acceptance on the continuation of their donation; (2) the direct effects of individuals' emotional utility, demonstrable utility, trust toward donee organizations on individuals' self-acceptance; (3) the direct effects of individuals' emotional utility, demonstrable utility on their trust toward a donee organization; (4) the indirect effects of individuals' self acceptance on two paths i.e. emotional utility${\rightarrow}$trust${\rightarrow}$self acceptance, and demonstrable utility${\rightarrow}$trust${\rightarrow}$self acceptance; (5) the indirect effects of individuals' individuals' trust toward donee organization on self acceptance on four paths i.e. emotional utility${\rightarrow}$trust${\rightarrow}$continuity of donation; demonstrable utility${\rightarrow}$trust${\rightarrow}$continuity of donation; emotional utility${\rightarrow}$trust${\rightarrow}$self-acceptance, and demonstrable utility${\rightarrow}$trust${\rightarrow}$self-acceptance; (6) the moderating effects of 'financial status' on the causal relationships in the prescribed structural equation model(SEM). In order to verify the moderating effect of 'financial status', multi-group analysis between each of the two groups were conducted. Research is based on a survey among 1116 donors who had made charitable, monetary contributions to social welfare organizations in Daegu and Kyungpook province. Data was collected from 29 organizations. In order to address the research questions, structural equation were employed. A variety of tests are conducted(metric invariance, critical ratio for difference, structural invariance, multi-group analysis, bias-corrected boot-strapping, latent mean analysis including Cohen's effect test).

The purpose of this study was to construct and test a hypothetical model about impact of childhood trauma on Relationship Addiction of Korean adults the multiple mediating effects of rejection sensitivity and internalized shame. A purposive sample of 465 Korean adults was recruited from three provincial areas. The collected data were then analyzed using SPSS 23.0 and AMOS 23.0 programs. For data analysis, descriptive statistics and structural equation modeling were performed. Multiple mediating effects analysis using phantom variable and bootstrapping were implemented to verify the mediating effect of the research model. We found no significant direct effect of childhood trauma on relationship addiction, but the effects of childhood trauma on Relationship Addiction were successively multi-mediated by internalized shame and rejection sensitivity (B=.265, p<.01), and single-mediated by internalized shame (B=.496, p<.01). Based on the results of this study, it can be suggested that in order to prevent relationship addiction of adults, it is necessary to first explore whether he has experienced childhood trauma and thereby has not only internalized shame but also rejection sensitivity.

This study was conducted to study the environment effects on live weight, carcass weight, dressing percentage, eye muscle area, backfat thickness, and marbling score, which are the carcass traits of Hanwoo, based on the estimates and all the possible regression for the selection of variable and significance test for 231,382 heads that underwent the carcass measurements. The average and standard deviation for the live weight, carcass weight, dressing percentage, eye muscle area, backfat thickness, and marbling score were 654.79${\pm}$91.61 kg, 362.30${\pm}$67.15 kg, 59.52${\pm}$0.03%, 81.79${\pm}$12.21 $cm^2$, 11.39${\pm}$5.40 mm, 4.38${\pm}$2.29, respectively. The live weight, carcass weight, dressing percentage, eye muscle area, backfat thickness, and marbling score for cow were 532.79${\pm}$78.38 kg, 313.40${\pm}$44.90 kg, 56.50${\pm}$0.03%, 75.24${\pm}$10.69 $cm^2$, 11.82${\pm}$5.10 mm, 4.30${\pm}$2.06, respectively, while for bull were 619.74${\pm}$93.27 kg, 376.89${\pm}$48.62 kg, 58.61${\pm}$0.02%, 85.61${\pm}$10.46 $cm^2$, 5.64${\pm}$2.71 mm, 1.41${\pm}$0.83, respectively, and for steer were 681.78${\pm}$70.72 kg, 415.23${\pm}$49.43 kg, 60.19${\pm}$0.02%, 88.29${\pm}$10.27 $cm^2$, 12.71${\pm}$5.23 mm, 5.42${\pm}$1.99, respectively. In the environmental variables selection based on the variables selection method, the examination by carcass traits suggested that the most appropriate model could be determined when five variables were selected for the live weight, carcass weight, dressing percentage, eye muscle area, and four variables for backfat thickness, and marbling score. When they were considered at a time altogether based on multiple traits, it was deemed to be desirable to insert all five variables into the variables for analysis. In addition, high significance was found by carcass traits.

The first purpose of this study is to understand the impact of the emotional intelligence of golf coaches on customer citizenship behavior. The second is to verify the moderating effects of gender roles in the relationship between emotional intelligence and customer citizenship behavior. In order to achieve the research purposes, 5 indoor and outdoor golf driving ranges were selected in Cheongju, and 318 customers were selected as the objects. SPSS 22.0 and AMOS 21.0 software was used. The following were identified as the result of the analysis. First, besides 'Emotional Control' and 'Helping Others' all four sub-factors of the golf coach's emotional intelligence had a noticeable influence on customer citizenship behavior. Second, the influence of emotional intelligence differed according to the gender of coaches. In the case of male coaches, emotional intelligence had an impact on all factors except transmission. In the case of women, it was found that feedback, helping others and emotional control had an impact on all factors except transmission. Therefore, these results show that in-depth research on the emotional intelligence of golf coaches is required. They also suggest that there will be a need to study how the gender of the coach affects customer citizenship behavior.
