The purpose of this paper is to measure the induced voltage of the downscaled and simulated overhead ground wire of a 22.9kV-Y distribution line. This study performed a test of the downscaled and simulated distribution line according to whether it is grounded or not and the value of the ground resistance. In order to verify the reliability of the data measured by the test, the data was analyzed using the Minitab 17 program. It was found that the induced voltage of the downscaled and simulated distribution line is influenced by the value of the ground resistance. It was also found that the ground resistance obtained at a certain point is closely related to whether electric poles are grounded or not. The analysis results of the measured test data with a statistical method showed that the Anderson Darling (AD) was analyzed to be the smallest as 0.188 when the ground resistance of the electric poles had been maintained at $10{\Omega}$. In addition, the P value analyzed to be 0.894 which is in the proximity of the theoretical value of 1 and verified the reliability of the test data. It could be seen that the data measured by the downscaled simulation test forms a linear graph. It is thought that if a distribution line is installed in the same manner as the downscaled, simulated distribution line, the mean induced voltage will be reduced and reliability will be increased.

Purpose - This study classified consumers' value inclination to find out ways to enhance consumers' eco-friendly product purchase intention. Further, it verified the differences among eco-friendly product purchase intentions depending upon value inclination. Research design, data, and methodology - The structured model and hypotheses were established, and 202 copies of effective questionnaires were used. In order to verify the hypotheses, we used single regression analysis, multiple regression, 3-step mediating regression, and path analysis. Results - Individualism had a positive influence upon materialism, need for uniqueness, and face wants, and collectivism had a positive influence upon materialism only. Factors of self-expressive consumption inclination had a positive influence upon eco-friendly product purchase intention, and factors of value inclination also had a positive influence. Finally, self-expressive consumption inclination mediated between value inclination and eco-friendly product purchase intention. Conclusion - Consumers with individualism inclination felt the need to connect the ownership of an eco-friendly product with their extended self and, further, it was clear that not only the government but also enterprises should build up their public image regarding eco-friendly products.

Purpose - This study aims to determine the effects of marketing factors on the long-term purchasing behavior regarding industrial goods, using data from wholesalers and retailers. Research design, data, and methodology - We used multiple regression analysis and 3-step regressions to investigate causality. We used 177 questionnaires targeting wholesalers and retailers of industrial goods. Results - First, long-term purchasing behavior is positively related only with advertising and marketing factors. Second, the relationship between marketing factors and brand value show that the physical environment, word-of-mouth advertising, and publicity are positively related, except advertising and sales promotion, respectively. Third, brand value and long-term purchasing behavior are positively related. Finally, brand value is not a mediator between marketing factors and long-term purchasing behavior. Conclusion - This study suggests that industrial goods providers should use marketing strategies that are different from those used in the consumer market. Further, if they want to maintain long-term relationships, they should increase their brand value.

Purpose - The purpose of this paper is to find out a range of cues that trigger employees to willingly make efforts for corporate development in small and medium enterprises. This was determined by assessing the effects of employees' value inclination on their job satisfaction and organizational citizenship behavior as well as how they perceived their organizational support. Research design, data, and methodology - A total of 126 valid questionnaire sheets collected from SME employees were analyzed with SPSS 24.0 and AMOS 24.0 involving simple regression analysis, multiple regression analysis, hierarchical moderated regression analysis and 3-step mediated regression analysis. Results - The analyses highlighted employees' personal value inclination had positive effects on their job satisfaction, which in turn enhanced their organizational citizenship behavior. Meanwhile, individualist and collectivist inclination exerted greater effects on job satisfaction and organizational citizenship behavior, respectively. The study also revealed that perceived organizational support moderated the relationship between job satisfaction and organizational citizenship behavior. Conclusion - Hence, CEOs in SMEs should avert any dichotomous analysis of their employees' value inclination, respect their personal value inclinations and also apply factors that could raise their job satisfaction. Likewise, it was shown that SME employees need to make personal efforts for organizational development.

Purpose: As the shared kitchen sector evolves into a new trend in the restaurant industry, not only operational support but also the physical environment for services is ranked as an important success factors. Therefore, the purpose of this thesis is to study the effect of shared kitchen service quality on experiential value, relational commitment, and long-term orientation. Research design, data, and methodology: In this study, a questionnaire was used to verify the structural relationship between shared kitchen service quality, experiential value, relational commitment, and long-term orientation for tenant companies in shared kitchen companies. The data were analyzed by using Partial Least Square-Structural Equation Modeling (PLS-SEM). Result: Facilities and support for the service quality of the shared kitchen had a positive (+) effect on the experiential value, and the environment did not. In addition, experiential value showed a significant positive (+) effect on relationship commitment and long-term orientation, and relationship commitment showed a significant positive (+) effect on long-term orientation. Conclusions: It was confirmed that the support quality among service quality affects the relationship formation. Thus, attention should be paid to activities to support stable business activities from the perspective of B2B services.

Purpose: The purpose is to verify the impact of the store environment on interpersonal service quality (ISQ), shopping value and patronage intention, as well as the moderating role of the store format: supermarkets vs hypermarkets. This is significant as previous studies on retailing neglected the effect of interpersonal service quality on the experiential shopping value. The comparison of the model between two retailing formats (hypermarkets and supermarkets) provides a significant contribution and responds to a need to provide insights regarding the moderation of the store types on the contribution of interpersonal service quality and experiential value to customer's retention. Research design, data, and methodology: The hypotheses have been tested after analyzing the data of a survey among 405 consumers exiting stores representing various retailing stores in Tunisia. A Structural model have been finally verified by a path analysis after applying a confirmatory factorial analysis. Multigroup analyses on AMOS allowed to verify the moderation of store types. Results: Results mainly show that patronage intention is affected by the experiential perceived value dimensions. The latter is a direct consequence of ISQ and an indirect outcome of perceived shopping environment. The impact of value, environment and ISQ is moderated by the store type.

Purpose - The purpose of this paper is to provide a political registration point for analyzing the economic impacts on the national economy from the REITs distribution industry in our country. The REITs distribution industry was introduced in 2001 to accelerate the corporate restructuring process and advance the real estate market. During its establishment, the REITs distribution industry faced difficulties; however, the industry grew rapidly through interest from institutional investors, thus mitigating the establishment problems by 2006. In Korea, more than 108 REITs were operating as of the end of June 2015. REITs contribute significantly to the national economy. The economic impacts on the national economy of the REITs distribution industry was analyzed using input-output (I-O) analysis with respect to production, imports, value-added, and employment. Research design, data, and methodology - The research used an I-O analysis of the activities of the REITs distribution industry in the national economy. The I-O analysis methodology analyzes the economic effects that influence other industries with respect to one unit of external investment. The data for this analysis were the I-O table of 2013 as published by the Bank of Korea in 2014. Results - The findings of this study are as follows. First, if an external input to the REITs distribution industry is 1 won, the overall impact of the product is 1.3869 won, the import induction is 0.0002 won, and the value-added induction is 0.7656 won. A new investment of 659.9 billion won into the REITs industry was estimated to produce a gross effect of 915.2 billion won. Second, if an external input to the REITs distribution industry is 1 billion won, the employment-inducing effects are estimated at 19.6394 individuals. The employment-inducing coefficient of 19.6394 for the REITs distribution industry indicates that the industry created significant employment-more than other industries-because the coefficient was 2.2 times the 2013 industry average employment-inducing coefficient of 8.8. Third, the investment effects of the REITs distribution industry on production induction, value-added induction, and employment induction are assumed to be large in business support services, financing, communications and broadcasting, and professional, scientific, and technical services. Conclusions - The REITs distribution industry was analyzed as having a strong employment inducing, high value added effect. The REITs distribution industry is an excellent alternative for the government authority to create multilateral jobs. Because the REITs distribution industry has a significant positive impact on the national economy, it should be developed. However, the I-O methodology has restrictions with respect to the fixation and timing of the input coefficient. Follow-up research is expected to supplement the analysis method at a specific point in time.

A design of reliability qualification test based on performance distribution is developed. In general, the performance of an item degrades as the time goes by and the failure of an item occurs when the performance degradation reaches the pre-determined critical level. This article considers the reliability qualification test based on a more tightened critical value at the earlier stage to reduce the evaluation testing time and cost. A numerical example is provided to illustrate how to use the developed reliability qualification test.
