The purpose of this paper is to introduce the notions of L-fuzzy topological towers by using a completely distributive lattic L and show that the category L-FPrTR of L-fuzzy pretopoplogical tower spaces and the category L-FPsTR of L-fuzzy pseudotopological tower spaces are extensional topological constructs. And we show that L-FPsTR is the cartesian closed topological extension of L-FPrTR. Hence we show that L-FPsTR is a topological universe.

This study was carried out to find out the factors affecting on organizational commitment of hospital employees. For the purpose, the questionnaire-based research was done with 1280 hospital employees who were working in 2 university hospitals and 4 general hospitals located in Taegu City and Kyungpook Province from November 20, 1997 to December 22, 1997. The results of the study were summarized as follows. There were significant correlations among environmental variables, psychological variables, structural variables, vertical conflict, horizontal conflict, job satisfaction, and organizational commitment. By path analysis, variables such as pay, work involvement, work definiteness, met expectations, positive affectivity, distributive justice, job security, expectations before entering a hospital had significant positive effect on job satisfaction in order of size, while, vertical conflict, job opportunity, and horizontal conflict had significant positive effect on job satisfaction in order of size, while, vertical conflict, job opportunity, and horizontal conflict had signifecant negative effect in order of size. Variables such as job satisfaction, job security, work involvement, pay, vertical conflict, met expectations, distributive justice, positive affectivity, work unit control, job autonomy, and job routinization had significant positive direct effect on organizational commitment in order of size, while, job opportunity, job hazards and resource inadequacy had significant negative direct effects in order of size. It was found that the following variables, listed in order of size, had significant total effects on organizational commitment : job satisfaction, job security, job opportunity, work involvement, pay, met expectations, distributive justice, positive affectivity, job hazards, and work unit control. In considering abovc findings, it is recommended that programs for job satisfaction promotion, job security, decrease of intent to leave, work involvement promotion, adequate pay, met expectations, distributive justice, positive affectivity promotion, job hazards decrease, and work unit control grant should be implemented to increase organizational commitment.

Purposes: Based on samples of government officials who are working at public health centers, following research examines the Effect of Organizational Justice on the relationships between Followership and Organizational Citizenship Behavior and analyzes the moderating effect of Leader-Member Exchange. Methodology: For the methods, Sphericity verification, Exploratory factor analysis, Correlation analysis, Causal relation, Mediating effect of followership and Moderating Effect of The Leader-Member Exchange have been analyzed with SPSS 22.0 & AMOS 22.0 Ver. Findings: As a result of Correlation analysis, Predictive validity and Construct validity have meaningful effect. Also, In case of Path analysis, distributive justice and interactional justice have meaningful effect but procedural justice has no such effect on Followership. As a result of Mediated effect of followership analysis, distributive and interactional justice have positive impact on (Organizational and Interpersonal). As to the mediation effect of followership analysis, It is shown that distributive and Followership have meaningful effect on In-group, not Out-group. Lastly, It is shown that procedural justice and Followership have no meaningful effect on both In-group and Out-group. Practical Implications: For the implications, distributive justice and interactional justice have positive impact on Followership, while procedural justice has no such impact on Followership. Also, It also possibly has same result to the moderating effect of Leader-Member Exchange. Consequently, It is recognized that a fair process without a fair result cannot be valued. also, We can know that reward for procedural justice is evaluated to kind of negative.

With the rapid growth of the internet, electronic commerce has become accepted as one of the major purchasing channels for consumers. As more and more consumers search for and purchase products through the internet, intra-industry competition of electronic commerce has become fierce. Therefore, electronic commerce service providers pay attention to factors that prevent existing customers from leaving there services in the service failure situation. In this regard, electronic commerce service providers should make service recovery efforts for consumer recovery satisfaction after service failure. In this study, we suggest that procedural justice, interactional justice, distributive justice and authenticity have positive impacts on recovery satisfaction. In addition, we also propose that involvement plays moderating roles in the relationships between procedural justice, interactional justice, distributive justice, authenticity and recovery satisfaction. We collected empirical data for this study over a period of two weeks from subjects who had service failure recovery experiences through electronic commerce. A total of 224 complete and valid responses were obtained. We carried out data analysis using a two-step methodology with SPSS 20.0 and SmartPLS 2.0. The first step in the data analysis was to establish the internal consistency, convergent validity, discriminant validity of the constructs. In the second step, we examined the structural model. The empirical results support the proposed model and partly identify the moderating effect of involvement differences. The moderate effect results show that procedural justice, distributive justice and authenticity have different impacts on recovery satisfaction in two groups. Cognitive factor such as the procedural justice and distributive justice have stronger impacts on recovery satisfaction in the high-involvement goods than in the low-involvement goods, while emotional factor such as authenticity has a stronger impact on recovery satisfaction in the low-involvement goods than in the high-involvement goods. We expect that this result will provide researchers and managers who are interested in electronic commerce service failure recovery with useful theoretical and practical implications.

Purpose - This study has the following objectives. First, it seeks to build an integrated model that can analyze the path through which headquarters, subsidiary competence, and knowledge transfer performance influence subsidiary performance. Second, it analyzes the influence of the specificity of technology as a moderating effect factor on knowledge transfer process. Third, it will conduct an empirical analysis on distributive manufacturing MNEs and suggests an implication for companies that actually need technological localization. The difference of this study are as follows. First, unlike the existing studies, this study can expand a theoretical discussion as it uses subsidiary performance as the dependent variable. Second, it sets the specificity of technology as a moderating effect factor, not an antecedent, and can draw a theoretical implication. Research design, data, and methodology - This study built a path analysis model to identify the influence of the disseminative capacity and absorptive capacity of distributive manufacturing MNEs on subsidiary performance. Based on the previous studies, it set 19 items as 5 latent variables, and established 6 hypotheses by including the moderating effect of the specificity of technology between them. The final 203 companies were selected as analysis samples through a survey questionnaire. For empirical analysis, the study used PLS (Partial Least Square) that is based on structural equation model. Results - The empirical analysis result demonstrated that both headquarters' disseminative capability and subsidiaries absorptive capacity had a positive influence on knowledge transfer performance. Knowledge transfer performance also had a positive influence on subsidiary performance. In the analysis of moderating effect, the specificity of technology acted as a significant moderating variable only between knowledge transfer performance and subsidiary performance; it did not show a statistically significant moderating effect among disseminative capability, absorptive capacity, and knowledge transfer performance. Conclusions - The empirical analysis results of this study demonstrate the importance of disseminative capability and absorptive capacity in knowledge transfer to subsidiaries from the distributive manufacturing MNEs in Korea. The analysis on the moderating effect indicates that the specificity of technology in Korean companies influences on the process of making achievement by using the transferred knowledge.

Companies have attempted to build a rational and future-oriented new personnel system in order to adapt and survive in a rapidly changing environment. Recently, Samsung, LG, SK, and CJ, which are large domestic corporations, have been introducing new types of simplified personnel systems competitively. Although there are several prior studies that tried to classify these simplified personnel systems from a strategic point of view, there is a lack of empirical research in terms of the specific types from the perspective of employees. Therefore, in this study, an empirical study on the simplified personnel system which has currently been highlighted was carried out. The relationship between perceived justice (i.e., distributive justice and procedural justice) and organizational effectiveness (i.e., organizational commitment and innovative behavior) were tested. In addition, the mediating role of cognitive attitude as well as the moderating role of cognitive intensity in the simplified personnel system were investigated. The results of structural equation model using 157 survey data show that both distributive and procedural justice have a positive effect on cognitive attitude toward the simplified personnel system, which in turn leads to increased organizational commitment and innovative behavior. Interestingly, it is found that cognitive intensity intensifies the effect of distributive justice on cognitive attitude, whereas it attenuates the influence of procedural justice as expected. This study is among one of the first empirical studies focusing on the simplified personnel system and expands the concept of related variables such as perceived justice, cognitive attitude, and cognitive intensity in this context. Moreover, by clarifying the causal relationship between perceived justice and organizational effectiveness through the roles of cognitive attitude and cognitive intensity, it could provide several practical implications to managers who are interested in the introduction and early settlement of simplified personnel systems in a successful manner.

This study verified the influence of distributive justice on burnout and inspected the mediating effect of empowerment of personnel in rehabilitation facilities. We surveyed 321 personnel in facilities of Daejeon and Chungnam areas. The main methods are structural equation model analysis and confirmatory factor analysis. The important analysis result is that distributive justice influenced burnout negatively and mdiating effect of empowerment was identified. According to analysis results, some measurements were proposed to reduce personnels' burnout. For increasing distribution fairness, compensation by objective evaluation of ability and workload, establishment of transparent compensation system, improvement of working conditions of irregular workers are required. In order to improve empowerment, leadership education for managers and operation of related programs, voluntary participation of employees in programs, provision of supervision and education of empowerment are needed.

Background: This study investigated the structural relationships among justice, test anxiety, and school reliability s non-face-to-face tests of dental hygiene students. Methods: A survey was conducted with 267 dental hygiene students. The survey items included general characteristics, opinions on evaluation, the fairness of non-face-to-face tests (distributive, procedural, and interactional justice), school satisfaction, and school reliability. For statistical analysis, independent-sample t-tests, one-way ANOVA, and structural modeling analyses were performed. Results: Among factors that directly affected distributive justice and reliability towards non-face-to-face tests, the higher the interactional justice (β=0.401, p<0.001) and distributive justice (β=0.232, p=0.002) levels, the higher the school satisfaction. The higher the school satisfaction (β=0.606, p<0.001) and procedural justice (β=0.299, p<0.001) levels, the higher the perceived reliability of the school. Factors that indirectly affected school reliability included interactional justice (β=0.243, p=0.010) and distributive justice (β=0.141, p=0.010). Interactional justice (β=0.592, p=0.010) and distributive justice (β=0.208, p=0.010) were the factors affecting school satisfaction. Moreover, factors that influenced school reliability were distributive justice (β=0.56, p=0.010), interactional justice (β=0.332, p=0.010), procedural justice (β=0.229, p=0.010), and distributive justice (β=0.116, p=0.010). Conclusions: Students will trust and be satisfied with schools when schools and professors sufficiently provide information on face-to-face tests and ensure proper procedures to achieve reasonable grades as rewards for exerted time and effort. Furthermore, this study provides a reference base for developing a variety of content for fair, non-face-to-face tests, thereby allowing students to trust their schools.
