The purpose of this study was to identify the effect of dental hygienists' perceptions of dental organizational culture and professional identity on organizational commitment. A survey was conducted with 310 dental hygienists working in dental hospitals and dental offices. If dental hygienists experience organizational cultures as having different degrees of organizational commitment, then the type of organizational culture and commitment may be important variables in understanding and reducing the turnover rate of dental hygienists and improving workplace performance. Efforts to form a healthy and positive organizational culture may therefore be necessary. The organizational culture most recognized by the dental hygienist was hierarchical culture (3.39) and the least recognized was task-orientated culture (2.71). The professional identity of the dental hygienist was 3.75 and the organizational commitment was 2.98. Correlation analysis was conducted to investigate the relationship between dental organization culture type, professional dental hygienist identity, and organizational commitment. As a result, professional identity and organizational commitment showed positive(+) correlation with innovation oriented culture and relationship oriented culture. Among the organizational culture types, relationship-orientated culture (p<0.001) and innovation-orientated culture (p=0.006) were significant influences on organizational commitment, and professional identity did not have a significant influence. The regression model was found to be statistically appropriate (F=11.857, p<0.001) and the model explaining power was 14.9%. These results suggest that efforts to create a relationship-orientated culture and an innovation-orientated culture and to reduce the hierarchical culture can be a strategy to enhance the organizational commitment and the professional identity of dental hygienists.

Many researches and validations for the complexity metrics of the object-oriented systems have been studied. Most of them are aimed for the measurement of the partial aspects of the systems, for example, the coupling between objects, the complexity of inheritance structures, the cohesion of methods, and so on. But the software practitioners want to measure the complexity of overall system, not partial. We studied the complexity of the overall structures of object-oriented systems by analyzing the class diagram of UML. The class diagram is composed of classes and their relations. There are three kinds of relations, association, generalization, and aggregation, which are making the structure of object-oriented systems to be difficult to understand. We proposed a heuristic metric to measure the complexity of object-oriented systems by putting together the three kinds of the relations. Tn analyze the complexity of the structure of a object-oriented system for the maintainability of the system, we measured the degree of understandability of it, the reverse engineering time to draw a class diagram from the source codes, and the number of errors in the diagram. The results of this experiment shows that our proposed metric has a considerable relationship with the complexity of object-oriented systems. The metric will be helpful to the software developers for their designing tasks by evaluating the complexity of the structures of object-oriented systems and redesigning tasks , of them for the future maintainability.

The principal objective of this study is to examine the relationship between the emotional intelligence and customer orientation in airline service context. Moreover, this study was designed to test the moderating effect of social support to provide fundamental and practical data for airline industry. In this study, 2 hypotheses based on literature reviews were employed. A questionnaire was also developed based on previous studies. A convenience sample of 233 flight attendants was surveyed and a total of 214 usable questionnaires were analyzed. Then the data and hypotheses were examined using multiple regression analysis using SPSS 18.0. The results are as follows. Firstly, emotional intelligence was divided into 'self-emotional appraisal', 'other's emotional appraisal', 'regulation of emotion' and 'use of emotion' according to the literature review. Analysis showed that emotional intelligence has partial effect on customer orientation accordingly. Secondly, social support has partial moderating effects between emotional intelligence and customer orientation. Continuous and systematic training program which build up team work should be conducted to administer 'emotional intelligence'.

This paper investigates the Moderating effect of entrepreneurship on the relationship between market orientation and international performance in Korean Ventures. Literature revealed that an appropriate alignment between firm strategic orientation and market positioning is critical because of its impact on firm performance. The alignment is especially crucial for SMEs as a result of their limited resource base. However, studies have not adequately accounted for the joint effect of entrepreneurship and market orientation on firm performance in different environments as foreign markets. Drawing upon a sample of 217 internationalized Korean Venture Business, it presents evidence related to mainly moderating effects of entrepreneurship on market orientation-international performance. The Key conclusion from the evidence is that market orientation, alone and in conjunction with certain entrepreneurship dimensions, is positively related to firm international performance. More specifically innovativeness and proactiveness have positively moderated the relationship between market orientation and international performance in Korean Ventures.

This study is to examine the impact of sales franchisor's relationship-oriented efforts(flexibility, problem solving support, customization, information exchange, and supervisor characteristics) on relationship quality(satisfaction, trust, and commitment) and recontract intentions. In order to analyze proposed model, this study collected the 233 franchisees with owner or hired manager. The data were analyzed with SPSS/PC 18.0 and AMOS 18.0. First, to test unidimensionality and nomological validity of the measures of each construct we employed a scale refinement procedure. The result of reliability test with confirmatory factor analysis warranted unidimensionality of the measures for each construct. The findings are as follows: First, relationship-oriented efforts had positive effects on relationship quality (satisfaction, trust, and commitment) of franchisee. Second, satisfaction had positive effect on trust, but did not on recontract intentions. Third, trust had positive effects on commitment and recontract intentions, respectively. Finally, commitment had a positive effect on recontract intentions. At the end of this paper, managerial implications and limitations and future research directions were suggested.
