최근 정보통신서비스 시장은 다양한 요인에 의해 서비스 사업자간의 경쟁심화와 고객요구수준의 향상 등의 추세가 강화되고 있으며, 경쟁양상 측면과 고객이 사업자에게 요구하는 서비스 제공특성 등의 측면에서 많은 변화가 일어나고 있다. 특히, 정보통신서비스에 대한 서비스 제공 품질수준과 관련하여 SLA (서비스수준협약)의 중요도는 점차 증대하고 있으나, 대부분 해외의 선진사레나 고객의 요구내용 (VOC)을 여과 없이 반영해서 제공하는 추세여서, 사업자의 입장에서는 SLA를 제공하는 과정에서 다양한 유형의 문제점을 안고 있으며, 실질적인 효과를 거두고 있는 사례를 찾아보기 힘든 상황이다. 이와 같은 배경에서, 본 논문에서는 최근 다양한 분야에서 폭 넓게 활용되고 있는 6 시그마 방법론에서 제시하고 있는 다양한 도구들을 활용하여, 사업자가 SLA 제공체계를 수립하는 과정에서 필요한 서비스품질 보증항목의 도출 및 보증수준의 설정, 측정과 관련된 다양한 요소에 대한 설정 및 관리방법, 보상수준의 설정 등에 대한 체계적인 제공방법에 대해서 제시하고자 한다.

As VoIP systems move to wireless environments with much higher average packet loss rates than wired networks, it becomes less possible for the network to assure a reasonable QoS. So, real-time quality monitoring for mobile VoIP applications is an important issue to be explored. In this paper, we explore perceptual quality dependency on two parameters: the burst loss rate and average burst length. Also, we propose a simple 'moving average' approach with $\alpha$ aiming to measure those parameters on real-time basis. In order to find how accurately the two parameters measured estimate the real perceptual quality, we compare actual measured PESQ scores with estimated value by matching the measured quality metric to the trained MOS table. Finally, we propose the quality-based accounting system, which can set obvious continuities between quality and billing.

This study measured the quality of Elderly Day Care Services by surveying service users; data were analyzed to see the causality between quality of services, customary satisfaction, referral intention, and repurchasing intention, and to find out the mediating effect of customary satisfaction. The quality of Day Care Services has been measured based on the SERVQUAL model, and structural equation model has been used to observe the causal connection between the five factors, tangibles, reliability, responsiveness, assurance and empathy, and customary satisfaction, referral intention, and repurchasing intention. The following is the main result from the causal effect model affecting the customary satisfaction and repurchasing intention by five quality factors of the service quality. First, it was shown that tangibles and responsiveness, as quality factors, directly affected the customary satisfaction, and reliability, credibility, and empathy did not. Second, it was shown that tangibles, reliability, responsiveness and empathy, quality factors, did not directly affected the referral intention and the repurchasing intention. But the effect of service quality on referral and repurchasing intention was mediated by customer satisfaction. Third, it is shown that customary satisfaction directly affected the referral intention and the repurchasing intention.

많은 기업들이 기업 내 또는 기업간 통합을 위해 웹서비스 시스템을 도입, 구축하고 있다. 하지만 기업관리자들은 기대했던 만큼의 실질적인 성과를 체감하고 있지 못하며 투자효과 분석 또한 미흡한 실정이다. 현재 웹서비스의 평가는 웹서비스의 서비스 품질 관리측면에서의 분석이 이루어 지고 있으며 웹서비스가 기업의 비즈니스에 가져다 주는 가치분석에 대한 연구는 미흡한 실정이다. 본 연구에서는 선행연구를 통해 웹서비스의 도입으로 인해 기업에 발생하는 이익을 분석하여 기술적 가치와 비즈니스적 가치로 분류하고 이를 바탕으로 가치의 측정을 위하여 웹서비스의 이익을 비용절감과 가치증대의 관점으로 새롭게 정립하였다. 본 연구의 결과는 기업이나 공공기관에서 웹서비스의 이익을 인식하는 새로운 방법으로 활용될 수 있을 것이다.

The purpose of this study was to identify the effect of education service quality (quality of professor service, quality of curriculum service) on career decision-making, self-efficacy, career decision level, and career preparation behavior. Appropriate measures were developed and tested on 426 respondents of Gyeongnam province in South Korea with a cross-sectional questionnaire survey. To ensure the reliability and validity of the questionnaire, frequency analysis, reliability analysis, and validity analysis were conducted. To ensure the reliability and validity of the measurement model, the CFA(confirmatory factor anlaysis) were conducted. The SEM(structural equation modeling) analysis was undertaken to perform the path analysis among the variables and to assess the suitability of the model. MCFA(multi group CFA) and MSEM(multi group SEM) were performed to confirm the moderation effect. Results of the study are summarized as follows: Firstly, education service quality has positive effects on career decision-making self-efficacy. Second, career decision-making self-efficacy has positive effects on career decision level and career reparation behavior. Third, career decision level has positive effects on career reparation behavior. Finally, it was found there exists a moderating effect of freshman/registered student between education service quality, career decision-making self-efficacy, career decision level, career preparation behavior. As a result of this study, it is suggested that investigation of extraneous variables which help to improve career preparation behavior and career decision level as for career of university student will contribute to university education.

The measurement of information system (IS) effectiveness is critical to understanding of the value and efficacy of IS actions and IS investments. In this paper, we propose a new model of the user satisfaction index for ISs and present the user satisfaction index which is measured by the proposed model. Based on the representative theories and models in the field of marketing and IS, we propose a new user satisfaction index model and verify the new model through the analysis of structural equation model. The proposed model consists of four basic dimensions : information quality, service quality, systems quality, and user satisfaction. Also, users' royalty and complaint are adopted as the additional dimension in this model. Data was collected from the ITFIND users to measure their satisfaction index. We, then, suggest some strategic guidelines for the better ITFIND which may useful when the system designers consider upgrading of the system in the future.

This study on CRM oftKorean restaurant guests to test the emotional response and behavioral intention. Three kinds of variables(service quality, information quality, system quality) from Korean restaurant guests were set to test the CRM. Results of the multiple regression analysis revealed a positive significant relationship with respect to quality of service, quality information, and quality system with all customer emtional reaction. Second, the results also found that the three independent variables of quality of service (${\beta}=.104$, P<.01), information quality (${\beta}=.215$, P<.001), and system quality (${\beta}=.682$, P<001) had a significant positive effect on the dependent variable for customer behavior (+). Third, CRM quality of service, quality information, and quality of the restaurant system are shown to influence the behavior and it also showed that both the part-mediated effects.

This study examined the factors that affect the relationship between low price coffee shops service quality and brand image, and rrevisit intention. A total of 225 questionnaires were distributed to consumers, of which 210 were deemed suitable for analysis after the removal of 15 unusable responses. In order to perform statistical analyses required in the study, the SPSS 18.0 Statistical Program was used for frequency analysis, factor analysis, and reliability analysis, correlations, and regression analysis. The results of exploratory factor analysis showed that four factors regarding service quality were extracted from all measurements with a KMO of 0.864 and a total cumulative variance of 73.235%, With regard to brand image, one factor was extracted with a total cumulative variance of 66.497% and a KMO score of 0.885. One factor for revisit intention was extracted that accounted for a total cumulative variance of 60.192% and a KMO score of 0.845. All factors were significant to 0.000 and the correlation between variables was significant. Thus, based on the results, the main research hypothesis that identifies the relationship among service quality, brand image and revisit intention was partially adopted.
