As service firms continue to seek unique sources of sustainable competitive advantage, service quality has been discussed as a potential alternative to traditional skills and sources. The information of customers is generally believed to be a key component in creating corporate responsiveness to customer requests. In order to develop and maintain long-term close relationships with customers(CRM), service firms need to build an effective and ongoing service quality information system(SQIS). Service firms that formally collect customer-related information and internal service quality information were to be more responsive. The purpose of the present study is twofold. 1. How to nicely get the information on the service quality. 2. How to build a SQIS. One of numerous examples from financial service-sector firms is given to show that SQIS can be developed to improve service quality This paper investigates SQIS of a Korean commercial bank as an example. Implications and strategies for building an effective SQIS for financial service-sector firms are discussed, and directions for future research are indicated.

DNA sequence alignment algorithms in computational molecular biology have been improved by diverse methods. In this paper, we proposed a DNA sequence alignment algorithm utilizing quality information and a fuzzy inference method utilizing characteristics of DNA sequence fragments and a fuzzy logic system in order to improve conventional DNA sequence alignment methods using DNA sequence quality information. In conventional algorithms, DNA sequence alignment scores were calculated by the global sequence alignment algorithm proposed by Needleman-Wunsch applying quality information of each DNA fragment. However, there may be errors in the process for calculating DNA sequence alignment scores in case of low quality of DNA fragment tips, because overall DNA sequence quality information are used. In the proposed method, exact DNA sequence alignment can be achieved in spite of low quality of DNA fragment tips by improvement of conventional algorithms using quality information. And also, mapping score parameters used to calculate DNA sequence alignment scores, are dynamically adjusted by the fuzzy logic system utilizing lengths of DNA fragments and frequencies of low quality DNA bases in the fragments. From the experiments by applying real genome data of NCBI (National Center for Biotechnology Information), we could see that the proposed method was more efficient than conventional algorithms using quality information in DNA sequence alignment.

This paper presents an automated construction quality nonconformity control method. Existing quality control process are confined attributed to the dependence on human quality personnels. They are inefficiency for continuos quality improvements and may cause project schedule delays when any nonconformity is handled timely fashion. For sure, It is important to identify the add hoc quality nonconformity control processes and to implement them into an automated system that controls its' work-flow. It would be desirable to develop the construction project quality nonconformity control system using Building information modeling(BIM) and Information and Communications Technologies(ICT). It may provide an effective platform to prevent quality issues that exist in the existing quality management practice.

The purpose of this study is to measure the library online service quality based on the expectation and the service performance from the users' point of view. The online questionnaire was developed based on SERVQUAL, however information quality dimension was added on it, and the survey was conducted within a research library. The factor analysis for effecting library online services showed that 5 service dimensions were loaded discretely, and information quality was put in the other dimension. The IPA (Important Performance Analysis) result confirmed that information quality, service reliability, and service assurance were considered as important factors : multiple regression analysis revealed that tangibility and information quality were the most significant dimension for the library online service.

Purpose: This study reexamines the test on the pricing of accruals quality. Theory suggests that information risk is a priced risk factor. Using accruals quality as the proxy for information risk, researchers have tested the pricing of information risk. The results are inconsistent potentially because of the information shock in the realized returns that are used as the proxy for expected returns. Based on this argument, this study revisits this issue excluding information-shock-free measure of expected returns. Research design, data and methodology: This study estimates expected returns using the vector autoregression model. This method extracts information shocks more thoroughly than the methods in prior studies; therefore, the concern regarding information shock is minimized. As risk premiums are larger in recession periods than in expansion periods, recession and expansion subsamples were used to confirm the robustness of the main findings. For the pricing test, this study uses two-stage cross-sectional regression. Results: Empirical results find evidence that accruals quality is a priced risk factor. Furthermore, this study finds that the pricing of accruals quality is observed only in recession periods. Conclusions: This study supports the argument that accruals quality, as well as the pricing of information risk, is a priced risk factor.

Purpose: This study was based on curation commerce that has been rapidly developing. It looked into the effect of curation commerce's quality of service factors (information quality, information interest quality, interaction quality, and personalization quality) on satisfaction and the mediating effect of consumer empathy and shopping value between service qualities and consumers' satisfaction with curation commerce. Research design, data, and methodology: The survey was conducted on 273 consumers who used Chinese curation commerce services. The research data was analyzed using the Smart PLS 3.0 program. The empirical analysis was conducted with reliability and validity analyses of the questionnaire and hypothesis test. Results: As a result, only the quality of information had a direct impact on satisfaction. The remaining service quaility factors (information interest quality, interaction quality, and personalization quality) were found to affect satisfaction through utilitarian value or consumer empathy. Conclusions: This study is meaningful in that it selected the service quality factors experienced by consumers about curation commerce services in line with the bright market prospects of curation services. In addition, the significance of this study was to reveal the psychological mechanism of the process in which the quality of service reaches consumer satisfaction.

This paper classifies the success factors of collaboration system in the shipbuilding industry. We propose the structural model that identifies the relationship between the success factors and organizational performance. To test empirically the relationship between the factors, we developed the measurement of each factors. This paper has examined the relationship between the independent variables and the mediating variables, also has examined the relationship between the parameters and a final dependent variable. The independent variables are as follows, (1) quality of system including reliability, flexibility, and accessibility, (2) the quality of information including contents, expressiveness, and (3) the partner relationship including the information sharing and the compatibility of strategies. The mediating variables are user involvement, parter trust, and user satisfaction. The final dependent variable is business performance. The hypotheses test proved that the system quality significantly affect user satisfaction, the information quality positively influence on the user participation, and the information sharing and strategic fit of partner relationship positively affect partner trust. Also, the user participation and partner trust significantly affect user satisfaction. Finally, the user participation, user satisfaction, and partner trust have a decisive effect on the organizational performance. The results of hypothesis test verified that the quality of information and system, also partner relationship are important to operate successfully the collaboration system in the shipbuilding industry. Also, the mediating variables are important to explain the structural relationship between the independent variables and organizational performance.

Total Quality Management (TQM) is the aggregated management philosophy for quality including production, operation, human resource, leadership, marketing, and etc. TQM is the advanced concept and philosophy rather than traditional "Quality Control" or "Quality Assurance". Nowadays, downstream costs has been increased, that made cost accountants' attention to costs of quality. Many countries have developed their own quality awards system in order to improve overall national quality level. The Deming Prize of Japan and Malcolm Baldrige National Quality Award (MBNQA) of United States are two representatives of quality prizes. We compared the two awards by means of their history, objective, coverage, and judging criteria. Deming Prize has a longer history than MBNQA. Deming Prize selects five winners a year, while MBNQA has two or three areas. The biggest difference is judgement criteria. The Deming Prizes focuses on statistical control which is a traditional quality control method, while MBNQA concentrates on modem business concept such as customer satisfaction. The suggestions to these awards are: evaluate more on information of quality; evaluate more on inter-functional relationship between quality control function and other link more financial success.e financial success.

This study reviews and modifies general IS success models to find success factors of WIS(Web-based Information Systems) and to confirm the relationship between WIS success and user's satisfaction of web use. A WISSM(Web-based Information Success Model extended to include EQ(E-Quality) is developed to anticipate user's intention to use Web-based Agricultural Information System and fit into the survey data from 252 WIS users of RDA(Rural Development Administration). PLS is applied to estimate a structural model based on EQ-WISSM to test hypotheses including 1) users reach a high level of intention to use Web-based Information Systems when they feel a high level of interactivity among an 'E-Quality', 'Decision Making Support Satisfaction' and 'Task Support Satisfaction', and E-Quality boosts intention to use Web-based Information Systems. The results show high path coefficients and $R^2$ values and find followings; First, the EQ-WISSM explains the user's intention to use WAIS quite well. Second, E-Quality can be used well in web-based IS environment to predict IS Success. Finally, this research finds the importance of 'Task Support Satisfaction' as a mediator between 'Decision Making Support Satisfaction', 'E-Quality' and 'Intention to Use'.
