The Service sector has increased dramatically in importance over the last decade, both internationally and in the Korea. Deregulation of services, growing competition, fluctuations in high quality demand, and the application of the Information Technologies are presenting a considerable challenge to service companies. In gas or oil companies are exposed to foreign competitions, price and promotion competition with other companies. Usually Service Quality includes five dimensions: Reliability, Responsiveness, Assurance, Empathy, and Tangibles. Customers use these five dimensions to form their judgements of service quality, which are based on a comparison between expected and perceived service. The intention of this thesis is to study on the effect of Service Quality upon the Customer Satisfaction in gas or oil station, based on SERVQUAL.

This study applies the Analytic Hierarchy Process (AHP) to evaluate service quality of Third-Party Logistics (3PL) service providers. For this, we first conceptualize five dimensions of 3PL service quality (i.e. tangibles, reliability, responsiveness, assurance and empathy). We then apply the AHP method to determining the relative weights of five service quality dimensions and eventually selecting the best 3PL service provider. To implement this idea in practice, we conduct an empirical study on four companies providing 3PL services in Korea.

IEC 61850 based substation automation system mainly consists of a various of protective and control IEDs. In order to implement the system, All of them should require the performance verification of IEC 61850 communication services for the assurance of interoperability throughout the digital network. This paper shows a research result on the testing method of IEC 61850 control communication interface of IEDs according to IED IEC 61850 conformance test procedures.

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.

오늘날 우리가 개발하는 소프트웨어 시스템은 사람의 실수로 인하여 문제가 생기는 경우가 너무나도 많다. 소프트웨어 테스팅은 품질보증에서 가장 중요한 부분이며, 특히 소프트웨어의 명세, 디자인, 코드 구현 부분에 대한 객관적인 평가를 가능하게 한다. 국내에서는 아직까지는 소프트웨어 테스팅 및 품질보증 활용의 경우가 미흡한 실정이지만 외국의 경우 개발비용의 40% 이상이 테스팅에 소요되는 경우도 있다. 본 고에서는 해외 IT 기업의 테스팅 수행 현황을 조사함으로써 IT 분야에 있어서 소프트웨어 테스팅 및 품질보증의 역할이 무엇인가를 살펴보도록 하겠다.

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.

Currently, the e-commerce market in Korea is growing rapidly, particularly in online commerce, and transactions through SNS are constantly increasing. This study assessed the quality of service based on SNS by modifying and combining SNS-based applications and services. Two hundred and sixteen surveys from an online survey conducted using a cumulative sampling technique were analyzed. The confidence, empathy, responsiveness, reliability, perceived usefulness, and customer satisfaction were independent variables. The perceived usefulness, customer satisfaction, and net profit were considered dependent variables. The results of 11 hypotheses were derived through SPSS 25. The results show that the perceived usefulness and customer satisfaction are affected by assurance, empathy, responsiveness, and reliability. In addition, SNS - based commerces show a significant relationship between perceived usefulness, customer satisfaction, and net benefits. The significant results are expected to help in future related research.

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.
