The purpose of this study is to forecast patient satisfaction and service value through the staged regression analysis of the relation between each factor and its satisfaction and service value, following the measurement of the quality of dental care service that patients recognize. And a self-administered survey was used for this study. The subjects of this survey were 394 outpatients of dental clinics located in K city in the period from Dec. 5, 2004 to Feb. 19, 2005, the questionnaire was composed of a total of 31 questions to measure the quality of overall dental care service(22 questions), the patient satisfaction(6 questions) and the service value(3 questions). The 7 points Likert scale ranging from "very poor"(1-point) to "very high"(7-point) was used for these questions The results of study could be summarized as follows: 1. The most useful index to predict patient satisfaction turned out to be "internal environment", followed by "treatment process and waiting time", "dentist", "external environment", and "dental hygienist". 2. The service value had a significant effect on the "internal environment", "dentist", "treatment process and waiting time". 3. The most useful index to predict the service value turned out to be "treatment process and waiting time", followed by "internal environment" and "dentist". Today, the quality of dental care service is becoming a prime concern since it is directly connected to a matter of survival of medical service organizations. Dental clinics desperately need patient-oriented marketing strategies in order to actively cope with changing medical environment. They also need to thoroughly examine possible measures to maximize the service value by establishing a variety of service strategies which can promote service quality that patients recognize.

As the Internet service is expanding rapidly, portal sites, a gateway tn the net, are attracting increasing attention these days. As the Internet service has expanded rapidly, so has the interest for portal sites,, which serve as a gateway to the net. Despite the tendency, however, research on a measure by which to evaluate the quality of portal sites or development of such measures has not been fully pursued. As online services, faced with profitability, are considering 'charge per view', the development of a set of quality evaluation measures for portal services will prove to become a valuable instrument in constructing competitive strategies that are vital for survival and growth of a firm. In that regard, this study aims to develop a set of evaluation measures for Internet portal sites by empirically investigating the most common offline measures for quality of services, SERVQUAL, retail SERVQUAL and other evaluation measures for IT-related online services. Moreover, the study offers the strategic implications of the defined measures.

The gap-based SERVQUAL model is a popular service quality determinant due to its superior diagnostic capacity over alternative explanatory frameworks. However, some researchers criticize the performance of the SERVQUAL model and propose alternative service Quality measurement constructs. Nevertheless, it is argued that the superior diagnostic capacity of SERVQUAL is its key strength; and that any criticism made of it when making comparison with alternative models does not reflect the differing nature of scales of statistical analysis. Arguably, the only limitation of a gap-based model is misinterpretation of customers' evaluation and perception of a service. In this research, the gap score is transformed into a ratio score. Also, empirical tests and implications are presented to support this alternative contribution to the body of knowledge.

The purpose of this study was to identify convention service attribute that affecting participants' satisfaction and intention-to behavior. theory and existing literature related convention service are reviewed. Based on the literature review, the measurement scale was developed and used for collecting the data. A total of 171 useful sample was collected and utilized for the study. factor analysis, regression analysis, cluster analysis, and ANOVA were operated in SPSS. Three convention service factors were identified. It was found that these three factors affected participants' convention satisfaction and intention-to-behavior. Theoretical and managerial implications were discussed.

This paper analyzed major factors affecting video quality in IPTV (Internet Protocol TV) services in multicasting under our lab network environment similar to practical IPTV service networks. We measured video qualities for the broadcasting traffics in IPTV multicasting with or without applying QoS (Quality of Service) technique. The measurements allowed us to extract thresholds of network measurement factors affecting the quality for the service. It will be a good choice that the factors can be a reference to ensure stable video quality for practical IPTV services in multicasting.

There are big differences in six sigma projects between manufacturing processes and transactional/service processes. This paper analyzed the differences between the two areas by examining 18 six sigma case studies in Korean companies. To characterize six sigma case studies, step-by-step questions and check criteria were developed based on 12 step DMAIC methodology. On the basis of those characterized data, the differences between two areas were analyzed. Significant differences were found in the number of CTQs, validation of measurement systems, methods to determine improvement objectives, the methods to elicit improvement plans and types of control systems. The most significant difference was that statistical tools were widely used in manufacturing processes, but qualitative tools were used in transactional/service processes during improvement phase.

In recent years, as the operations of the ports are privatized, the operators in the ports are competing in order to host more customers. Under such circumferences, it is preferred that the operators set plans to provide the customized services to the customers by precisely recognizing and analyzing the needs of the customers for the bright futures of the ports rather than to host the customers by just lowering the freights. The present studies aimed to analyze on how the service capabilities of the ports affect the customer's trust, the customer's satisfaction and the repurchase intention have extracted the variables and the measurement items from a lot of the preceding studies conducted on the other industries, part of which were modified depending on the views from the ports and the statuses of the ports, so the measurements were conducted.

This paper presents the prediction of remaining service life of the concrete due to steel corrosion caused by the following three cases; carbonation, using sea sand and using deicing salts. The assessment of initiation period was generalized considering the existing perdiction models in the literature, corrosion experiment and field assessment. To evaluate the prediction equation of rust growth, the corrosion accelerating experiments was performed. The polarization resistance was measured by potentiostat and the conversion coefficient of polarzation resistance to corrosion rate was determined by the measurement of real mass loss. Chloride content, carbonation, cover depth, relative humidity, water-cement ratio(W/C), and the use of deicing salts were taken into account and the resulting prediction equation of rust growth was proposed on the basis of these properties. The proposed equation is to predict the rust growth during any specified period of time and be effective in particular for predicting service life of concrete in the case of using sea sand.

In this paper, we proposed some valuable analysis results of cultivation campaign marketing in A mobile telephone company. The cultivation campaign marketing is a new outbound TM campaign strategy composed of 4 steps for new subscribers. During the analyses, attrition rate of A mobile company, outbound TM rejection rate, contact rate/call success rate and additional service attrition rate after subscription are measured as an effect of cultivation campaign. The results showed that there were no statistical significance in improving retention rate between customers experienced 4 step cultivation campaign and control group. However, the cultivation campaign had a better effect on improving response rate and success of selling additional service product of mobile company compared to general selling campaign. This is because cultivation campaign group had been taking care of from subscription time. It is suggested that cultivation campaign had better confined customers more likely to buy additional service to outbound TM for the sake of financial efficiency.
