One of the important components of this administrative reform is customer satisfaction. Every public enterprises introduced the Service Charter and Korean government took Customer satisfaction as the key index of public sector performance assessment. Most public enterprises introduced customer satisfaction management in an attempt to improve the quality of customer service. The government granted high incentives to excellent business innovative enterprises and developed additional indices, which are related to CS. From now on, every Korean enterprises must embody feasible customer satisfaction management and improve the quality of customer service In this research, we proposed a quality evaluation standard model which is suitable for the public enterprise based on the Service Quality Criteria, and examined the model. A 7-Point Likert Scale was used based on the five categories within the Service Quality: responsiveness, convenience, tangibility, sympathy and reliability, we analysed the validity and causal relationship among the factors within the model.

The purpose of this research is to explore the relationships among service quality's five factors(i.e., tangibles, reliability, responsiveness, empathy, and assurance) and customer satisfaction. The study used convenience sampling and selected certain consumers who visited coffee shop in BeiJing, China. Total 300 questionnaires was distributed and 18 unsuitable data were excluded for data analysis. These data were tested using SPSS 21.0. The results of this study are summarized as follows. First, the result of the relationship between coffee shops'service quality and customer satisfaction reveals that two of 5 service quality factors (i.e., assurance and empathy) had a positive effect on customer satisfaction only, and other service quality factors (i.e., tangibles, reliability, and responsiveness) had no positive influence on customer satisfaction. Limitations and future research directions of the study were also discussed.

The main objective of this study was to test the impact of service quality dimensions on customer satisfaction. The conceptual model proposed in the study postulated that service quality impacts on customer satisfaction directly. The model also postulated that service quality has a positive relationship with customer satisfaction, and tested them through Multiple Regression to find their significance. Questionnaires were distributed to gather data. The SERVQUAL instrument has a useful diagnostic role to play in assessing and monitoring service quality in banks. The results of the study confirmed the five factors of service quality with customer satisfaction were significant in all factors of service quality. Reliability, Responsiveness, Empathy, Assurance, and Tangibles are significant determinants of customer satisfaction. Thus, service quality can be used to predict customer satisfaction. The research has shown a positive relationship between service quality and customer satisfaction. This research concluded that service quality is the basic and also most important factor that impacts customer satisfaction. This finding reinforces the need for banks managers to place an emphasis on the underlying dimensions of service quality, especially on Assurance, and should start with improving service quality in order to raise customer satisfaction.

An optimization of the M/M/1 queue with impatient customers is studied. The impatient customer does not enter the system if his or her virtual waiting time exceeds the threshold K ＞ 0. After assigning three costs to the system, a cost proportional to the virtual waiting time, a penalty to each impatient customer, and also a penalty to each unit of the idle period of the server, we show that there exists a threshold K which minimizes the long-run average cost per unit time.

This study explores e-banking variables that affect client satisfaction in the Saudi Arabian banking industry spanning three dimensions: reliability, security concerns, and efficiency, which were chosen as predictors of customer satisfaction in the e-banking industry. A field survey using a self-administered questionnaire as a data collection instrument was adopted to collect the required data from a convenience sample of 250 participants of Saudi banking customers. The overall fit of the hypothesized model was tested using linear regression to find the rate of the independent factors' impact on the dependent variable. The study's findings revealed that there is a statistically significant relationship between the three dimensions and customer satisfaction in Saudi e-banking, with the largest impact being that of reliability, followed by efficiency, and finally security concerns. Also, the study found there was a significant difference in reliability which was considered more important for Saudis and there was a significant difference in efficiency, which was considered more important by males. The findings of this study suggest that these three dimensions are instrumental in e-banking customer satisfaction and that banks can gain a competitive edge by providing better services in these dimensions to sustain and develop their performance in the increasingly globalized banking industry.

The growth in services has focused issues of service quality both for commercial enterprises and across a range of public services and government institutions. The education sector, in particular, has undergone radical change to meet the needs of its varied constituents. This paper examines key issues in internal service, customer satisfaction, service quality, relational commitment as they apply in one particular education sector. The purpose of this study is to analyze effect of internal service on customer satisfaction, educational service quality. First, In the dimension of internal service, many factors affect internal customer's evaluation for overall satisfaction. They are categorized as five factors; tangibles, reliability, responsiveness, assurance, empathy. The results of this study supported the proposed conceptual framework overall. Therefore, we identified that internal service quality is the antecedent of an internal customer satisfaction, and the consequent variables of an internal customer satisfaction are educational service quality, external customer satisfaction. The major findings of this study are summarized as follows. First, some factors(tangibles, reliability, responsiveness, assurance, empathy) affected positively internal customer satisfaction. Second, external service quality affected positively educational service quality, external satisfaction. In other words, the more internal customers have experienced internal service, the higher internal service quality deliver educational service quality.

On the internet, the rating scores assigned by customers are considered as the preference information of themselves and thus, these can be used efficiently in the customer profile generation process of recommender system. However, since anyone is free to assign a score that has a biased rating, using this without any filtering can exhibit a reliability problem. In this study, we suggest the methodology that measures the reliability of rating scores and then applies them to the customer profile creation process. Unlikely to some related studies which measure the reliability on the user level, we measure the reliability on the individual rating score level. Experimental results show that prediction accuracy of recommender system can be enhanced when ratings with higher reliability are selectively used for the customer profile configuration.
