This study intends to examine the effects of CRM on the customer loyalty. Service quality, customer satisfaction, and organizational committment have been tested as mediating factors between the customers' perceived relational efforts and their loyalty. From 236 customers of insurance firms survey data have been collected and analyzed based on the structural equation modeling. The results show that firms' relational efforts have positive impacts on service quality and customer loyalty. Also, this study shows that service quality can play an important mediating role between CRM activities and customer satisfaction as well as organizational commitment, which have shown positive impacts on customer loyalty Consequently, firms need to design their CRM activities paying more attentions to the service qualify attributes, rather than asking too much from the target customers.

This study aims to find out the dimension of consumers' shopping values in internet clothing purchase, and the relation of their relational quality with shopping malls and their shopping behavior depending on the type of their shopping values. For this purpose, this study surveyed 343 male and female consumers in their 20s or 30s for empirical analysis who have ever purchased clothing through internet shopping malls. Respondents are selected using the convenience sampling through internet survey in July 2008. For statistical analysis, descriptive statistics, factor analysis, ANOVA analysis, Duncan test, and $X^2$-test are carried out using SPSS for Windows 12.0. The results are as follows. First, consumers' shopping value dimensions in internet shopping for clothes are found 4 factors of fun, economic utility, information, and shopping convenience. Second, based on shopping value dimensions, consumers are categorized into an practicality-seeking, an economic utility/fun-seeking, a fun-seeking, and an information/fun-seeking group. Third, there are significant differences in relational quality, customer loyalty, favorable word of mouth, and repurchase intention depending on shopping value-based consumer types. In particular, the economic utility/fun-seeking and information/fun-seeking group have higher values on relational quality and shopping behavior variables than other groups. Thus internet shopping mall businesses need to recognize these group of consumers as their core customers and develop programs to maintain a long-term relationship with them.

This study examines multiple quality optimization of the injection molding for Polyether Ether Ketone (PEEK). It also looks into the dimensional deviation and strength of screws that are reduced and improved for the molding quality, respectively. This study applies the Taguchi method to cut down on the number of experiments and combines grey relational analysis to determine the optimal processing parameters for multiple quality characteristics. The quality characteristics of this experiment are the screws' outer diameter, tensile strength and twisting strength. First, one should determine the processing parameters that may affect the injection molding with the $L_{18}(2^1{\times}3^7)$ orthogonal, including mold temperature, pre-plasticity amount, injection pressure, injection speed, screw speed, packing pressure, packing time and cooling time. Then, the grey relational analysis, whose response table and response graph indicate the optimum processing parameters for multiple quality characteristics, is applied to resolve this drawback. The Taguchi method only takes a single quality characteristic into consideration. Finally, a processing parameter prediction system is established by using the back-propagation neural network. The percentage errors all fall within 2%, between the predicted values and the target values. This reveals that the prediction system established in this study produces excellent results.

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.

This study presents a database quality evaluation framework. As a way to build a framework, this study expands data quality management to include data transformation processes as well as data. Further, an information structure graph is applied to represent data transformations processes. An information structure graph is absed on a relational database scheme. Thus, data transformation processes may be stored in a relational database. This kind of integration of data transformation metadata with technical metadata eases evaluation of database qualities and their causes.

Nowadays an information exchange on Bn such as B2B electronic commerce is spreading. Therefore the systematic and stable management mechanism for storing the exchanged information is needed. For this goal there are many research activities for connection between XML application and relational database. But because XML data have hierarchical structures and relational database can store only flat-structured data, we need to store XML data in object-relational database that support hierarchical structure. Accordingly the modeling methodology for storing XML data in object-relational database is needed. In order to build good quality application systems, modeling is an important first step. In 1997, the OMG adopted the UML as its standard modeling language. Since industry has warmly embraced UML its popularity should become more important in the future. So a design methodology based on UML is need to develop efficiently XML applications. In this paper, we propose a unified design methodology for In applications based on object-relational database using In. To this goal, first we introduce a XML modeling methodology to design W3C XML schema using UML and second we propose data modeling methodology for object-relational database schema to store efficiently XML data in object-relational databases.

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.

In recent studies, there has been much interest in the relationship between customer partnership and its effect on CRM success. Yet, there is little empirical work on it. This study empirically examines the relationship between customer partnership and CRM success in Korean companies. The findings indicate that the success of the relational systems(information technology and education/reward) is significantly related to trust to customer and customer partnership. The study also provides empirical evidence that trust and customer partnership is positively related to the new CRM success and the traditional CRM success.
