Purpose: The purpose of this study is to construct and verify a path model for the influencing factors on occupational stress of Vietnamese migrant workers in Korea. Methods: Participants were 193 Vietnamese migrant workers recruited from Foreign Workers Support Centers. Data were collected by a self-administered survey with copies of a Questionnaire written in Vietnamese. Data were analyzed with descriptive statistics, Pearson's correlation coefficients and path analysis using SPSS/WIN 23.0 and Amos 20.0 program. Results: Length of residence, homeland friends' and Korean colleagues'supports, and acculturation have been found to have significant direct effects on occupational stress of Vietnamese migrant workers. Meanwhile, Length of residence, homeland friends', Korean colleagues', and their families' supports showed indirect effects on their occupational stress. What had the greatest direct effect on occupational stress of Vietnamese migrant workers was Korean colleagues' support. Conclusion: For reducing occupational stress of Vietnamese migrant workers, it is necessary to strengthen their Korean colleagues' supports in work places. In addition, community organizations should take strategies to enhance homeland friends' supports and to improve acculturation of Vietnamese migrant workers.

The purpose of this study was to investigate the determinants of customers' information engagement, the behavior pattern from WOM to cooperation, and the moderator in the behavior pattern. The proposed three determinants, boundary personnel's citizenship behavior, satisfaction, and commitment were significant antecedents to WOM, but not to cooperation. The path coefficient from WOM to cooperation was significant and hereby the voluntary level of cooperation was found as a higher level of voluntary behavior than WOM. Additionally, the path from WOM to cooperation was moderated by customer involvement, as the path coefficients from WOM to cooperation varied by the level of involvement.

Via hydrosilation-alkenylation approach using hydrosilanes (HSiMeCl2 and HSiCl3) and allylmagnesium bromide with siloxane tetramer (MeCH2=CHSiO)4 as core molecule, noble carbosilane dendrimers with 12, 24, 48 and 96 allylic end groups have been prepared. The reaction path of the repetitive alkenylation and hydrosilation was monitored by means of NMR spectroscopic measurements. Every step for the formation of dendrimer provided almost quantitative yields as pure dendrimers. Based on the observation of UV spectroscopic measurements of Gn (n=1-4) molecules containing allylic end groups, the maximal molal absorption coefficients (εmax) at λmax and the number of double bonds proved an exponentially increased correlation.

In the severely competitive market, brand extension strategy has become a key strategy to the companies that are trying to expand in the new market and to cut down the marketing cost. In conclusion, following results are deduced. First, hypothesis 1(H-1) refers to the relationship between image of extension brand and attitude of extension brand, and it shows path-coefficients value of 0.43, and t-value of 4.21 which supports the hypothesis statistically. Second, H-2 is the result of the analysis of relationship between attitude of extension brand and loyalty of extension brand and consequently the hypothesis is supported by the path-coefficients value of 0.29 and t-value of 3.08. The results of this study provided very useful information for both foodservice industry and academics. At first, in the theocratical point of view, this study suggests a new concept the foodservice brand extension. Consequently in marketing point of view, the results of this study recommend several strategies of foodservice brand extension using foodservice image, attitude and loyalty.

Online game business has emerged as the most lucrative entertainment industry, with over 10 million players in South Korea and over 30million in Japan in 2005. While the interactive entertainment market continues to expand, with many new online game publishers entering the market, relatively little theory has been developed about which factors influence online gamers' behavioral intentions (i.e., loyalty, satisfaction, words of mouth, etc.) in this area. The purpose of this research is to investigate the relationships among the gamers' satisfaction, trust toward game publishers, the role of online game community, social reputation, and the managerial support of game publishers. We also examine the differences between Korean and Japanese gamers concerning the relationships of these key success factors. The structural model is tested with the data from entire data samples (i.e., Korean and Japanese gamers pooled together) and each of the sub-samples (i.e., Korean and Japanese gamers taken separately). Properties of the causal paths, including standardized path coefficients, the significance of difference, and variance explained for Trust and Satisfaction in the hypothesized model, are presented. Following the model test, we conduct a test of the differences in path coefficients between Korean and Japanese gamers. Statistical results show that, compared to Japanese gamers, Korean gamers had a greater salient effect on Social Reputation in determining. Trust, in addition to placing a greater emphasis on Support of Game Publishers in determining Social Reputation. Other interesting results concerning game Publishers' strategy are also presented.

According with variations in principal agronomic traits of fourteen malting barley cultivars as affected by different seeding methods and seeding rates. the analysis and interpretation of correlation coefficients and path coefficients was intended. From all treatments (seeding methods and rates), the positive significant relations detected between flowering days and maturing days, however the negative between maturing days and culm length, number of grains per spike, yields, and between 1000 grain weight and one liter weight, respectively. Direct effects on the yields were greatest by number of grains per spike in case of narrow-spaced row seeding and number of spikes per m$^2$ and number of grains per spike among others in broadcast seeding method On the other hand, indirect effects were not recognized in any treatments.

The multiuser detection (MUD) based wireless receiver requires more accurate channel estimation than the single user detection (SUD) schemes such as Rake receiver, and hence the post processing is required for MUD to clean up the estimated channel coefficients by eliminating the noise only coefficients. The adaptive post processing method is proposed in order to provide more accurate channel responses and the power level of the background noise and interferences at the cost of the negligible processing delay compared to the conventional method based on the threshold test with the threshold value relative to the noise variance. The simulations are performed in 3GPP-TDD mode environment. The results show that the noise estimation error of the proposed method is maximum $10\%$, which is much smaller than $50\%$ maximum error of the conventional method.

The purpose of this research is to investigate the relationships among the perceived satisfaction, the perceived the trust, the commitment, the key features for mobile phone, the brand image, the switching cost and the repurchasing intention. We also examine the differences between Korean and Indonesian markets concerning the relationships of these key successfactors. The structural model is tested with the data form each of the sub-samples (i. e. Korean and Indonesian users taken separately). Properties of the casual paths, including standardized path coefficients, the significance of difference, and variance explained for trust, satisfaction, commitment and repurchasing in the hypothesized model, are presented. This study indicated that hardware (sound quality, LCD display, design) user interface (GUI, Menu, Key pad) and extra functions (camera phone, wireless internet, MP3 player) are the three important factors effecting the trust and the satisfaction. The proposed model has been newly tested from the technological prospective in order to get the more practical result. Following the model test, we conduct a test of the differences in path coefficients between Korean and Indonesian users. MSEM show that, compared to Korean market, Indonesian had more emphasized on extra-function for the mobile phone as well as giving more influence to the satisfaction from the brand image. It means Korean market consider the extra-function as basic or no-premium points. And the satisfaction has been effected by switching-cost in Korea but the trust in Indonesia. Other interesting result from the structural weight invariance indicate that, compared to Korean market, the brand-image has effected the satisfaction in addition to placing more the trust on determining the commitment in Indonesia.

The purpose to this study is to analyze the difference of trust toward Internet-only bank into two groups according to the gender. We specially examined whether there is any gap in the determinant of trust. For this, we attempted to analyze the significance of the difference in the path coefficients between the gender through latent mean and path analysis. As a results, the difference of the determinant of trust between the male and the female group occurred in the factor of benefit and security. Moreover, it reconfirmed that trust are later strongly extended to relationship commitment. These findings suggest that it's very important to establish a trust with customers.
