Recently the port logistics service has been recognized as a important function of the international logistics, therefore, a lot of papers have been issued concerning the measurement of the service quality of that. But in spite of variety of papers, we can not find out the papers concerning the model of the synthetic customer satisfaction. And also the most of papers concerning the customer satisfaction of service quality have been focused not by cognitive evaluation of the customer, but by affective response. In this thesis, the authors are postulating the model and hypothesis to achieve the research by using the Gr$\"{o}$nroos's model. In order to research the relationship between the port logistics service quality and the customers satisfaction, we are selecting the shipping companies located in Busan and Kwangyang as purchaser and the loading and unloading companies as supplier, and the questionnaires was performed to them. In the result of the empirical study, the technical quality of the port logistics service are affecting directly on the customer satisfaction, but the functional quality are affecting not directly on the customer satisfaction. And also the customer response(affective response) has been proved that it has been exercised as a intermediate role between the port logistics service quality and the customer satisfaction. Therefore it is proved that the affective response of the customer has been exercised a crucial role in the course of supplying the port logistics service.

HTTP(HyperText Transfer Protocol)는 월드 와이드 웹 분산 시스템이 객체를 인출하기 위해 사용하는 전송 프로토콜이다. HTTP는 연결 지향 프로토콜이므로 트랜스포트계층에서 TCP(Transmission control Protocol)를 사용한다. 그러나 HTTP는 TCP와의 상호운용이 좋은 편이 아닌 것으로 알려져 있다. 본 연구에서는 TCP의 성능에 영향을 주는 요인들을 살펴보고, HTTP 접근을 위해 TCP의 slow-start 오버헤드 및 연결에 소요되는 트랜잭션 시간과 TCP의 성능 향상 대안중의 하나인 T-TCP(Transaction TCP)의 트랜잭션 시간을 검토한다. 평균 대기 시간과 평균 반환 시간은 사용자의 서비스 품질을 만족시키기 위한 중요한 파라메터들이다. TCP와 T-TCP 트랜잭션 시간이 주어지는 경우 그러한 파라메터들의 계산 공식이 유도되었다. 실험 및 계산 경험을 통해 제안된 공식이 잘 작동됨을 확인하였고, 대역폭의 확장이 필요한 환경에 적용될 수 있으며 T-TCP의 시간 특성이 TCP 보다 우수함을 확인하였다. 아울러, 평균 대기 시간과 평균 반환 시간을 줄이기 위해 대역폭을 조합하여 서버를 분산하는 방법이 제시되었다.

Purpose - This study attempted to construct and validate a structural model of the relationship between the quality of medical services, perceived risk, reputation and customer satisfaction, which is the main concept of the relationship between large hospitals as well as small and medium hospitals and medical consumers. Through this verification, the small and medium hospitals are to find the way for wise coping in competitive situation with large hospitals. Research design, data, and methodology - This research developed a hypothesis by constructing a structural equation that reaches the satisfaction and the relationship between reputation of perceived risk and perceived risk of service quality perceptions of customers of small and medium hospitals. Research data were collected through a questionnaire survey of respondents who had medical service experience from small and medium hospital. A total data of 252 respondents were used as the sample for the final analysis and analyzed using SPSS 23.0 and AMOS 23. Results - As a result, the relationship of quality of medical service, reputation, and customer satisfaction among small and medium hospitals was consistent with the results of precedent studies, and the perceived risk has a significant impact on reputation, so the greater the perceived risk, the higher the preference for reputable medical institutions as large hospitals. In addition, it was found that the direct route from perceived risk to customer satisfaction was not significant, and reputation was found to have a full mediating effect on perceived risk and customer satisfaction. Customers who use small and medium hospitals prefer to use reputable medical institutions if their perceived risk is high, which is different from risk perception when specific targets are specified. Conclusions - In terms of the effect from customer satisfaction, not only the path of perceived risk → reputation → customer satisfaction, but also the quality of service quality → reputation → customer satisfaction. These findings suggest that small and medium hospitals are appropriately responding to competition with large hospitals, rather than focusing on the perceived risks and reputation of customers in establishing and utilizing competitive strategies to create new customers and preserve existing customers.

Recently the business environment surrounding the financial investment industry is changing rapidly, and the demands of customers (diversity and the cycle of change etc.) are getting shorter. In this context, it can be said that companies are forced to adopt an agile management environment. In particular, non-face-to-face channels, including MTS, is adopting the agile system into the digital finance sector from a company-wide and strategic perspective. This study analyzed the effects of MTS services' environment quality on customer satisfaction and continuous intention to use for MTS users who are rapidly increasing under the agile management environment in the financial investment industry. This study surveyed the quality of service environment (accessibility, convenience, design, security), customer satisfaction, and continuous intention to use for 350 MTS users. First, accessibility, convenience, and security of MTS service environment quality had a positive effect on customer satisfaction, and design was rejected Second, customer satisfaction has a positive effect on continuous intention to use. Third, convenience and security of MTS service environment quality have positive effects on continuous intention to use, and accessibility and design were rejected. The results of this study, together with demographic analysis, are expected to provide useful implications for MTS activation studies and securities firms' strategies.

The environmental changes in the Korean cosmetic medical service industry in the $21^{st}$ century are forming intense competition among medical institutions due to the quantitative expansion of its market. For stable growth of the cosmetic medical service industry, continuous quality improvement is necessary based on empirical research on the quality of cosmetic medical services rather than external expansion. The purpose of this study is to classify the quality attributes of cosmetic medical service using Kano model and to derive the degree of satisfaction and dissatisfaction of each quality attributes through Customer Satisfaction Coefficient (CSC). Through this, the study identified strategic priorities and suggested specific step-by-step approaches and quality improvement priorities that can increase customer satisfaction using the Potential Customer Satisfaction Improvement Index (PCSI Index). Based on SERVPERF, this study used measurement tools consisting of five dimensions : tangibles, reliability, responsiveness, assurance, and empathy. In addition, it was used of measurement items reconstructed into positive, negative, and satisfaction questions for Kano model analysis, CSC analysis, and PCSI Index analysis. A total of 300 medical consumers who experienced cosmetic medical services for the past one year in medical institutions such as plastic surgery and dermatology were collected with convenient sampling. As a result, urgent items for improving the quality of service using the PCSI Index, 'Consideration for customer benefits' in empathy category was followed by 'Immediate help' and 'Sincere response' in responsiveness category, and 'Understanding customer needs' in empathy category, respectively. That is, it is required to improve human service quality attributes such as empathy and responsiveness rather than physical service quality attributes. This study contributes practically in that it provides specific and discriminatory approaches to improve customer satisfaction on cosmetic medical service quality and suggests improvement priorities.

Background: To survey and analyze awareness and recognition during a non-face-to-face lecture, and satisfaction with among dental technology students. Methods: Total 179 undergraduates were surveyed from the Department of Dental Technology. Frequency analysis, cross analysis, independent sample t-test, correlation analysis, and multiple regression analysis were used for analyzing statistics. Results: Overall satisfaction with the non-face-to-face lecture was the highest (p=.037) while watching a recorded lecture in the theory curriculum subject. In the case of practical subjects, satisfaction with face-to-face lectures appeared to be higher (p=.039) compared to non-face-to-face lectures. Factors influencing the recognition of non-face-to-face lecture quality included awareness of a place to conduct a class and of face-to-face delivered lecture quality, satisfaction with face-to-face lecture, and satisfaction with non-face-to-face lecture. Factors affecting satisfaction with a non-face-to-face lecture included a place to conduct a class, the most effective theory non-face-to-face class method, the method of having been experienced the most among non-face-to-face lecture methods, and the recognition of non-face-to-face lecture quality. Conclusions: Future educational environment should include combined face-to-face and non-face-to-face lectures. An efficient educational indicator will be needed to evaluate learners' assessments and opinions about online classes, followed by its application to teaching methods.

The purpose of this study was to examine parents' perceptions towards, and the importance and performance levels of, foodservices in child-care centers and to suggest ways to increase foodservice quality and promote efficient operations in the future. A questionnaire survey was provided to 540 parents and the return rates 82%. The survey period was from June 20 to July 27,2007. The collected data were statistically analyzed with the SAS package program using descriptive statistical analysis, t-tests, ANOVA, Duncan's multiple comparisons, factor analysis, and multiple regression analysis. The results were as follows: The parents perceived that foodservice operations promoted their children's health and helped them form desirable dietary habits. The parents also had a high level of perception toward the need for foodservice, earning greater than 4.5 points out of 5 points. Their perceptions of foodservice quality were examined by four dimensions of importance and performance levels. While the parents gave 4 points or greater of 5 points to most quality attributes of importance level, they gave 4 points of less out of 5 points to most quality attributes of performance level. As for the importance and performance levels of the quality dimensions of meal service, the parents regarded sanitation as the most important dimension. IPA showed that 'organic food materials' was included as a 'focus here' area. The overall satisfaction level for foodservice was 3.59 out of 5 points. A higher level of satisfaction was shown when a dietitian was present as well as in public childcare centers. According to multiple regression analysis, 53.51% of the variance in the respondents' overall satisfaction scores was explained by factors such as food, sanitation, environment, and foodservice effects.

QoS 라우팅은 멀티미디어 응용 프로그램들이 요구하는 QoS 요구사항을 기반으로 이를 만족시킬 수 있는 적정경로를 찾아내는 라우팅 기법이다. QoS 라우팅은 네트워크의 동적인 상태를 반영하여 경로를 결정하기 때문에 응용의 요구를 만족시킬 뿐 아니라 네트워크의 활용율을 증대시키는 효과가 있다. 그러나, 네트워크의 동적인 상태 정보를 파악하기 위해서는 라우터들이 이러한 정보를 서로 교환하는 오버헤드가 발생하게 된다. 이러한 프로토콜의 오버헤드를 줄이기 위해 주기적으로 네트워크 상태 변화를 점검하여 변화의 정도가 어떤 값 이상일 때만 네트워크 상태 정보를 주고받는 방법이 제안되었다. 그러나 이렇게 주기를 사용하게 되면 주기가 큰 경우에는 라우터의 네트워크 상태 갱신 필요를 판단하는 파라미터의 민감성이 네트워크 상태 갱신에 거의 반영되지 않는다는 문제가 있다. 또한, 부정확한 네트워크 상태 정보에 근거하여 경로를 결정하는 경우 QoS 라우팅에 의해 적정 경로로 선택된 경로에 실제로는 요구된 정도의 자원이 없어서 자원 예약에 실패하게 될 수 있는데, 이렇게 되면 이미 자원 예약이 이루어진 경로의 일부에서 자원 예약을 해제해야 하는 등의 오버헤드가 커지게 된다. 본 논문에서는 이 두 가지 문제에 대한 기존의 네트워크 상태 갱신 정책 개선안을 제시하고 시뮬레이션에 의해 그 성능을 평가하였다.
