본 연구는 이동통신사의 멤버십카드를 소지한 고객을 대상으로 이동통신사가 제공하는 보상이 통신사만족에 영향을 미치는데 있어 고객유형의 조절효과를 확인하는 연구로서, AMOS의 개별모수 차이검증을 통해 보상프로그램 가치와 통신사 만족간의 관계에서 고객유형별(거래지향형/촉진둔감형) 차이가 있는 지를 밝히고 보상프로그램 가치들 간의 상대적 영향력의 차이를 비교하였다. 분석결과 먼저, 보상 실용성과 통신사 만족, 보상 쾌락성과 통신사 만족 간의 경로계수값이 유의한 차이를 보이지 않아 고객유형이 조절효과를 가지고 있다라고 보기는 어려웠다. 그러나 보상프로그램 가치들 간의 상대적 영향력에서 있어서 거래지향형 고객과 촉진둔감형 고객 둘 다 보상 실용성이 보상 쾌락성보다 더 크게 영향을 미쳤고, 보상 실용성의 경우 촉진둔감형 고객이 거래지향형 고객보다 더 큰 영향을 미침을 확인하였다.

This study aims to identify service factors that satisfy customers in the internet shopping mail context. The study examines the relationship between service qualify and customer satisfaction, and explores the moderating role of the internet community type (i. e., transaction community group, interest community group and fantasy community group). By analyzing 188 questionnaires, we found that out of the five service quality dimensions, only reliability, tangibility, assurance and responsiveness dimensions have positive effects on customer satisfaction. We also found that there is a significant difference in the relationship between service quality and customer satisfaction by the perceived type of internet community implications of the findings and future research directions are discussed.

We analyze queueing model with priority scheduling by supplementary variable method. Customers are classified into two types (type-1 and type-2 ) according to their characteristics. Customers of each type arrive by independent Poisson processes, and all customers regardless of type have same general service time. The service order of each type is determined by the queue length of type-1 buffer. If the queue length of type-1 customer exceeds a threshold L, the service priority is given to the type-1 customer. Otherwise, the service priority is given to type-2 customer. Method of supplementary variable by remaining service time gives us information for queue length of two buffers. That is, we derive the differential difference equations for our queueing system. We obtain joint probability generating function for two queue lengths and the remaining service time. Also, the mean queue length of each buffer is derived.

As the power industry moves towards open competition, there has been a call for methodology to evaluate power system reliability by using composite interruption cost. This paper presents algorithms to evaluate the interruption cost of distribution power systems by taking into consideration the failure source and the composite customer interruption cost. From the consumer's standpoint, the composite customer interruption cost is considered as the most valuable index to estimate the reliability of a power distribution system. This paper presents new algorithms that take into account the load by customer type and failure probability by distribution facilities while calculating the amount of unserved energy by customer type. Finally, evaluation results of unserved energy and system interruption cost based on composite customer interruption cost are shown in detail.

Customer reviews are one of the important sources for purchase decision makings in online stores. Online stores have tried to provide useful reviews in product pages to customers. To assess the usefulness of customer reviews before other users have voted enough on the reviews, diverse aspects of reviews were utilized in prevous studies. Style and semantic information were utilized in many studies. This study aims to test diverse alogrithms and datasets for identifying a proper classification method and threshold to classify useful reviews. In particular, most researches utilized ratio type helpfulness index as Amazon.com used. However, there is another type of usefulness index utilized in TripAdviser.com or Yelp.com, count type helpfulness index. There was no proper threshold to classify useful reviews yet for count type helpfulness index. This study used reivews and their usefulness votes on restaurnats from Yelp.com to devise diverse datasets and applied text mining approaches to classify useful reviews. Random Forest, SVM, and GLMNET showed the greater values of accuracy than other approaches.

Previous literature supports the importance of corporate social responsibility (CSR) by demonstrating its effects on various aspects of firm performance. However, the extent to which CSR contributes to social well-being, its original objective, has rarely been examined. The current research investigates the impact of customers' perceived CSR of service firms on customer happiness. Two studies confirm our proposition that perceived CSR increases customer happiness by enhancing perceptions of warmth and competence associated with the service company. Furthermore, we examine how the type of service moderates this effect. Specifically, we find that the indirect effects of CSR on customer happiness through perceptions of warmth and competence are stronger for credence services than for experience services. This research makes theoretical contributions to the literature on CSR, happiness, and service, and offers practical implications for marketing tactics, including fostering long-term customer relationships and monitoring the effectiveness of CSR activities and corporate budget allocations.

As the power industry moves towards open competition, there has been a call for methodology to evaluate power system reliability by using customer interruption costs. This paper presents an evaluation of the interruption costs for public customers in Korea using customer survey methodology. When various research results are examined, the evaluation of direct interruption costs becomes much more simplified. Especially, in the case of public customers, it is known that the evaluation of direct interruption costs is more useful. Accordingly, this paper selected the customer survey method to evaluate the interruption costs for public customers in Korea considering interruption and customer characteristics.

본 연구는 기업의 경영성과를 올리기 위한 방안으로 조직공정성이 고객지향성에 미치는 영향관계를 통해 호텔기업과 같은 서비스 산업에 도움이 될 수 있는 이론적, 실무적 시사점을 제공하는 것이 목적이다. 서울에서 근무 중인 호텔종사자를 대상으로 설문지를 배포하였고, 총 321명의 자료가 실증분석에 적용되었다. 조직공정성이 고객지향성에 미치는 영향관계를 알아보기 위해 다중회귀분석을 실시한 결과, 조직공정성의 하위변수인 분배공정성과 상호작용공정성은 고객지향성에 유의한 영향을 미치는 것으로 나타났지만 절차공정성은 유의하지 않은 결과를 도출해 냈다. 또한 호텔산업의 특성상 비정규직의 채용이 늘어남에 따라 정규직과의 조직공정성에 대한 인식차이가 고객지향성에 대한 영향관계를 알아보기 위해 차이분석한 결과 정규직 종사원의 분배공정성과 절차공정성이 고객지향성에 유의한 영향을 미치는 것으로 나타났으나, 비정규직은 유의하지 않은 결과로 나타나 가설은 채택되었다. 하지만 상호작용공정성은 정규직, 비정규직 모두 고객지향성에 영향을 미치는 것으로 나타나 고용형태에 따라 다를 것이다 가설은 기각되었다.

The study aimed to determine the impact of societal participation on the customer loyalty of Saudi banks and identify the statistical differences in customer loyalty according to sex, age, education level, and occupation type. The independent variable is corporate societal participation, and the dependent represents customer loyalty. Corporate societal programs have two dimensions: social participation and philanthropic participation. The research population consists of Saudi workers in three sectors: government, military, and private reached 3.58 million people in 2021. The unit of analysis is the Saudi employee in one formal industry and dealing with the Saudi banks that offered corporate societal participation programs. The research used the appropriate stratified sampling method, and the recommended sample size reached 387 respondents. A fully structured questionnaire is used. The study concluded that corporate social programs have not impacted customer loyalty, while corporate philanthropy programs strongly affected customer loyalty. On the other hand, there are no differences in customer loyalty according to demographics (sex, age, education, and occupation type). Finally, the study presents a set of recommendations in the field of corporate social responsibility and develops the local communities.
