An empirical comparison of static fuzzy relational models which are identified with different fuzzy implication operators and inferred by different composition operators is made in case that all the information is represented by the fuzzy discretization. Four performance measures (integral of mean squared error, maximal error, fuzzy equality index and mean lack of sharpness) are adopted to evaluate and compare the quality of the fuzzy relational models both at the numerical level and logical level. As the results, the fuzzy implication operators useful in various fuzzy modeling problems are discussed and it is empirically shown that the selection of data pairs is another important factor for identifying the fuzzy model with high quality.

The problem of the optimization of fuzzy relational models for dealing with (non-fuzzy) numerical data is investigated. In this context, interfaces optimization assumes particular importance, becoming a determinant factor in what concerns the overall model performance. Considering this, several scenarios for building fuzzy relational models are presented. These are: (i) optimizing I/O interfaces in advance (independently from the linguistic part of the model); (ii) optimizing I/O interfaces in advance and allowing that their optimized parameters may change during the learning of the linguistic part of the model; (iii) build simultaneously both interfaces and the linguistic subsystem; and (iv) build simultaneously both linguistic subsystem and interfaces, now subject to semantic integrity constraints. As linguistic subsystems, both a basic type and an extended versions of fuzzy relation equations are exploited in each one of these scenarios. A comparative analysis of the differ nt approaches is summarized.

In this paper, a research model is proved empirically which includes factors related on the purchase intention of smart car as high innovative product in advance of commercialization. As one of relating to consumer's expectation benefit factors, individual attribute factor includes product knowledge, individual innovativeness, and sociality. Consumer's expectation benefit factor includes perceived ease-of-use, usefulness, and enjoyment. As of switching cost variables, there are financial, uncertainty, relational and psychological switching costs factors. Analysis were performed using data from the 257 respondents as random sampling among potential consumers. Purchase intention were affected by individual innovativeness mediated by perceived enjoyment, and individual sociality by perceived ease-of-use and enjoyment also. Relational switching costs factor was only a significant control variable between purchase intention with consumer's expectation benefit factor. This result presents some implications for making the new smart car's detail concept and marketing strategy related to targeting the consumer as high innovative product and technology firms including smart car makers.

Previous studies have shown that country image affects consumers' valuation of products. Based on a literature review this paper identifies five dimensions (economic, political, relational, people and cultural image) and purifies them with Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). The data was gathered by using a structured questionnaire from 252 Korean consumers. Among the five dimensions of country image, this paper derives the three factors of country image for four countries (The United States, Japan, Australia, and China) - economic, relational, and cultural image. Then it examines the impacts of the three dimensions of country image on consumers' purchase intention of two industry types : industrial products vs. agricultural products. The result shows there is no difference between both of the two types in the impacts of country image on purchase intention. This implies that for managing the country image it not necessary to develop a communication strategy which is differentiated by industry types.

With the development of the culture industry, online transactions of cultural products are being activated, and offering information and establishing relationship with customers in web-site have an important influence on online purchase decision making. The purpose of this research is to examine the effect of information and relational benefits provided by online sales sites of cultural products on online purchasing intention, and to reveal through empirical analysis whether these influences show a difference between stage products and screen products. Looking at the results of the study, first, in the case of the whole, both information offering and relational benefits have a significant effect on online purchasing intention. Second, in the case of stage products(plays), product understanding information, economic relational benefits, and customization relational benefits showed significant effects, but product purchasing information showed no significant influence. Third, in the case of screen products(movies), product purchasing information and economic relational benefits showed a significant effect, but product understanding information and customization relational benefits had no significant effect. In conclusion, the impact of information offering and relational benefits on online purchasing intention differs according to cultural products, and economic relational benefit is found to be an important influencing factor on online purchase decision making in all cases. These research results are expected to be helpful in establishing differentiated marketing strategies including customer relationship management in online transactions of cultural products.

This study examines influences of service employees' relational efforts on gratitude, indebtedness and purchase behaviors. The results follower like these. First, service employees' relational efforts have positive effects on gratitude(feelings of gratitude and gratitude-based reciprocal behaviors). And gratitude has a positive effect on purchase behaviors. Second, service employees' relational efforts have positive effects on indebtedness and indebtedness has a positive effect on purchase behaviors. It means gratitude and indebtedness can use marketing factors to influence on consumer behavior. But, indebtedness showed significantly close to the threshold, and the impact of indebtedness on purchase behaviors has the lowest than feelings of gratitude and gratitude-based reciprocal behaviors. Thus, it needs to be careful to use indebtedness as a marketing factor.

This study examined different individual and environmental factors that affect children's experience of harassment from their peers. For the individual variables, gender, behavioral problems, and self-esteem were included in the anal)'sis. For the family variables, mother's parenting style and the socio-economic status of parents were examined, and for the school variables, the supervision of the teacher and the attitudes of the classmates toward bullying were used. Two forms of peer harassment, the overt form and the relational form were examined in this study. The sample consisted of 520 fifth grade children. Statistics and methods used for the data analysis were Cronbach's alpha, factor analysis, frequency, percentage, means, standard deviation, Pearson's correlation, and multiple regression. Several major relationships were found from the analyses. First, the more the children tend to internalize behavioral problems and have lower self-esteem, the more likely they are to get victimized by overt and relational forms of harassment. Boys experience more overt harassment than girls. Second, the more the mother's parenting style is permissive-nonintervening, or rejecting-restricting, and the higher the father's social status is, the more likely the child is subjected to overt and relational forms of harassment. Third, the more the children feel that the teacher is paying attention to bullying, the less the children are subjected to the overt form of peer harassment. Fourth, children's internalizing behavioral problems, mother's permissiveness-nonintervention, children's self-esteem, children's gender, and the supervision of the teacher regarding bullying significantly affected the experience of overt forms of harassment. A twenty two percent variance in the victimization of an overt form was explained by those variables. Children's internalizing behavioral problems, mother's permissiveness-nonintervention, children's self-esteem, and mother's rejection-restriction significantly affected the experience of relational form of peers harassment. Twenty six percent of the variance in the relational form of victimization was explained by those variables.
