The current trend toward the utilization of the Internet as a common means for the offer of heterogeneous services imposes to address the issues related to end-to-end service assurance in the inter-domain scenario. In this paper, we first present an architecture for service management in networks based on service level specifications (SLS). The architecture is designed to be independent both of the specific network technology adopted and of the high level service semantics. Then, we focus on a specific functionality of the proposed architecture: Resource allocation in the multi-domain scenario. A distributed admission control algorithm is introduced, its complexity is evaluated and a comparison with related solutions is provided.

To cope with the rapid emergence of competition, communication service providers are assigning marketers for the purpose of relationship marketing. However, the efficiency of relationship marketing has yet to be examined. This paper investigates the service quality determinants In relationship marketing through the telecommunication service marketers. By considering the specificity of the marketer´s role, the quality dimensions in SERVQUAL research have been modified. A survey has been conducted for the hypothesized seven quality dimensions. The results of the factor analysis show that the service quality determinants of relationship marketing are in fact four dimensions : empathy, reliability, image and tangibles. Here, the empathy dimension entails cost factor, and the reliability dimension includes responsiveness and assurance. The results also support the proposition, reported in SIRVPIRF research, that the quality of service should be measured only by the perceived achievement of the customer. This study provides useful insights into developing the strategy for effective relationship marketing.

In this study, we propose a technological system designed to provide machine vision-based automatic inspection and autonomous operation services for an entire process related to product inspection in wire harness manufacturing. The smart factory paradigm is a valuable and necessary goal, small companies may encounter steep barriers to entry. Therefore, the best approach is to develop towards this approach gradually in stages starting with the relatively simple improvement to manufacturing processes, such as replacing manual quality assurance stages with machine vision-based inspection. In this study, we consider design issues of a system based on the proposed technology and describe an experimental implementation. In addition, we evaluated the implementation of the proposed technology. The test results show that the adoption of the proposed machine vision-based automatic inspection and operation service system for multi-wire harness production may be considered justified, and the effectiveness of the proposed technology was verified.

The purpose of this study was to analyze related factors affecting profitability on general hospitals(300-499 beds). The data were derived from survey by the Korean Hospital Association on 33 hospitals during 10 years (from 1993 to 2002). Profitability was measured by 3 ratios - net profit to total assets, normal profit to total assets and operating margin to gross revenue - as dependent variables. Independent variables were classified by general factors (ownership, number of bed, period of establishment, region), financial factors (total asset turnover, current ratio, liabilities to total assets, personnel costs per operation profit, material costs per operation profits), productivity index(number of daily patient per nurse), the score of quality assurance activity and the time lag score. Multiple regression model was used in this study. First, Number of bed, region was not statistically significant for profitability. But ownership was affect positively to normal profit to total assets and operating margin to gross revenue. Private hospitals had higher profitability than that of public hospitals Second, the score of quality assurance activity was not statistically significant to profitability. Third, Those hospitals having more daily patient per nurse had significantly higher profitability than the others. Fourth, Those hospitals having higher proportion in total asset turnover had significantly higher profitability than other hospitals. But liabilities to total assets and liquidity ratio had no difference to the profitability. Those hospitals having higher proportion in personnel costs and material costs per operation profits had significantly lower hospital profitability than others.

This study purposed to analyze difference in the perception of service quality between physical therapy patients and physical therapists and to provide basic materials for maintaining high service quality that meets patients' expectation in each service area. For this study, we conducted a questionnaire survey with physical therapy patients and physical therapists in Jeju from the 6 to 30 of January, 2010. In the survey, we received 133 questionnaires from patients and 125 from physical therapists, and used them in analysis. The instrument used in this study to measure service quality was prepared by the researcher through adapting and supplementing the SERVQUAL model developed by Parasuraman et al (1991). For our physical therapy environment, and it consisted of a total of 23 questions in five areas, namely, tangibility, reliability, responsiveness, assurance, and empathy. Patients' perception of service quality was high in order of reliability, assurance, empathy, responsiveness, and tangibility. In four areas with exception of reliability, quality perceived by patients was lower than that perceived by physical therapists, and particularly in responsiveness(t=2.82, p=.00) and empathy(t=2.02, p=.04), the difference between patients and physical therapists was statistically significant. In order to reduce the difference in the perception of service quality between patients and physical therapists, it is considered necessary to enhance physical therapists' perception of service quality and to prepare measures for improving service equality so that services would be provided through respectful communication with maintaining the dignity of patients, rather than focusing on disease.

The medical tourism industry, a convergence of medical services and tourism, has been getting more and more popularity as a new value-added industry in the 21st century. Accordingly, the number of professional workers within this industry has been increasing, and the role of educational institutions to cultivate well-equipped human resources has also become critical. However, compared to practically activated medical tourism-related education programs, studies investigating the effectiveness of these education programs are relatively rare. Therefore, this study attempts to examine the effect of five dimensions of medical tourism education service quality (i.e., tangibles, reliability, responsiveness, assurance, and empathy) on learners' education satisfaction and transfer of education training. In addition, the moderating roles of national relations as well as organizational characteristics (i.e., transfer climate and support of supervisors and colleagues) in the relationship between education satisfaction and transfer of education training are further verified. The results of the structural equation model (SEM) using 151 samples from respondents with experience in completing medical tourism education programs reveal that tangibles, reliability, and assurance are found to have a significant impact on education satisfaction, which in turn leads to a high level of transfer of education training. Moreover, it is found that national relations and support of supervisors and colleagues play a moderating role. This study would provide guidelines for improving the efficiency of educational institutions, creating outcomes for learners' affiliated firms (e.g., hospitals), and promoting medical tourism at the national level from the perspective of medical tourism education.
