In this study, we propose a integrated model of logistic regression, artificial neural networks, support vector machines(SVM), with case-based reasoning(CBR). To predict respondents in the direct marketing is the binary classification problem as like bankruptcy prediction, IDS, churn management and so on. To solve the binary problems, we employed logistic regression, artificial neural networks, SVM. and CBR. CBR is a problem-solving technique and shows significant promise for improving the effectiveness of complex and unstructured decision making, and we can obtain excellent results through CBR in this study. Experimental results show that the classification accuracy of integration model using CBR is superior to logistic regression, artificial neural networks and SVM. When we apply the customer response model to predict respondents in the direct marketing, we have to consider from the view point of profit/cost about the misclassification.

Social network services based on openness, connectedness, and mass participation are reshaping many aspects of how companies conduct business and create value for their customers. For instance, Facebook and Twitter are expected to play a pivotal role as a new communication channel through which companies-forge close relationships with their customers for co-creation of value for mutual benefits. Given the potential of social network services, it is not surprising that many companies have strategically invested in social network services to reach out to customers. Despite the growing interest in social network services as a platform to connect companies and their customers, few guidelines exist about how managers can effectively utilize social network services in forging relationships with their customers. As such, scholars should pay greater attention to how firms can successfully develop relationships with their customers on social network services. In particular, this study employs the S-O-R (stimulus-organism-response) framework as a theoretical lens to develop a research model that explains customers' participation in the value co-creation platform that companies opened on Twitter. According to the S-O-R framework, certain types of individuals' behaviors can be best understood based on a causal link from environmental stimulus to organism, and response. We apply the S-O-R framework to understand how ubiquitous connectivity (stimuli) can influence customers' experience (organism) with companies on Twitter, which in turn influence their participation behavior (response). Two steps have been undertaken to empirically test the research model. First, we conducted a content analysis of tweets written by customers who follow companies on Twitter. As a result, we found event/promotion participation, company support, and giving feedback as three specific types of customer participation behavior. Second, we conducted a web-based survey to test research hypotheses in the research model. Participations in the survey were solicited to customers who followed companies on Twitter. As a result, a total of 115 respondents have completed the survey. Data were analyzed using the partial least square (PLS) technique. The results of data analysis suggest that ubiquitous connectivity (stimuli) had strong positive effects on perceive usefulness, perceived enjoyment, and perceived intimacy (organism). Perceived intimacy showed positive effects on customer participation behavior (response), such as event participation, company support, and giving feedback. Perceived enjoyment was found to have strong positive effects on company support and giving feedback. On the other hand, perceived usefulness did not have significant impacts on the three types of customer participation behavior.

품질에 대한 정의는 계속 진화하고 있다. 최근 들어서는 고객관점의 품질을 중시하며 고객의 잠재적 요구를 얼마나 잘 충족시키고 있는가에 대한 관심이 커지고 있다. 카노가 제안한 2차원적 품질의 개념은 고객만족에 중요한 품질속성을 발견하는 데 유용한 프레임워크를 제공하며 제품 및 서비스 개발을 위해 널리 적용되고 있다. 카노모델은 제품 및 서비스 품질요소를 매력적, 일원적, 필수적, 무관심, 그리고 역 품질요소로 구분한다. 그 중 매력적 요소를 발견하는 것은 고객만족의 효과적인 달성에 중요하다. 하지만 카노가 제시한 분류방법은 고객의 애매하고 복잡한 생각을 다루는 데 한계가 있다. 고객응답에는 그 자체로 불확실성과 불완전성이 포함되기 때문이다. 이를 극복하기 위해 본 논문은 퍼지기법을 이용한 품질요소 분류절차를 제시한다. 수치실험 결과, 제안된 방법은 고객의 다양한 반응을 수용하는 데 효과적이며 잠재적 요구를 식별하는 데에도 유용한 것으로 나타났다.

The Battery Energy Storage System(BESS) has lots of advantages such as load levelling, quick response emergency power(spinning reserve), frequency and voltage control, improvement of reliability, and deferred generation and transmission construction. The economic feasibility requires justification from the customer side of meter to promoting the dissemination of BESS nationally. In this paper, we proposed the economic assessment model of customer owned Battery Energy Storage System(BESS) which is complemented and improved the existing model. The proposed model is applied to the typical customer type(light-industrial commercial, and residential) which are taken from the statistical analysis on the load profile survey of Korea Electric Power COmpany (KEPCO). The economic assessment performed for each customer type to justifying their economic feasibility of BESS installation from the economic measures such as payback period, overall benefits, ROI, and ROR. The results of this paper are useful to the customer investment decision making and the national energy policy & strategy.

With the increase of using Internet in clothing shopping, the gathering of customer information based on online research is emphasized. The purposes of this paper summarized the several aspects of on-line research as new data collection methods and investigate some characteristics through reviewing extant literature on online research. We explored a conceptual model of response behavior for the purpose of the literature in a manner which enhance a deeper understanding of online response behavior. This model was focused on exchange paradigm instead of a "help-the-sponsor" approach. The proposed conceptual framework included questionnaire design, response incentive, commitment, convenience, expertise, response behavior (satisfaction and attitude), and online research performance.

Purpose - There have been numerous studies investigating the effects of corporate social responsibility initiatives on corporate associations or corporate images. In line of this research stream, current research examined the potential impact of customer participation in the process of corporate social responsibility initiatives on attitude toward the company. This research differentiates from previous studies that it is the first to connect corporate social responsibility and customer participation. Specifically, we suggest a structural model on corporate associations which was classified into corporate ability associations and corporate social responsibility associations that the more the customers participate in initiating corporate social responsibility, corporate associations were formed more positively. And this leads to the increase of revisit intentions through customer satisfaction. Research design, data, and methodology - To test our research model, we collected data of real consumers of a large discount store in Korea. At the large discount store, customers were given an opportunity to participate the discount store's CSR activity program. We performed field survey and collected data of 146 respondents. We analyzed the data using PASW statistics 21.0 and AMOS 16.0 in order to test our structural model. Results - The results showed that consumers who participated more in initiating corporate social responsibility revealed higher score for corporate ability associations and corporate social responsibility associations. These corporate associations had a positive effect on customer satisfaction, which leads to higher attitude toward revisit intentions. Specifically, hypothesis 1.1 "As Customer participation in CSR process increases, the evaluation of CA associations will be positive,"was supported. Hypothesis 1.2 "As Customer participation in CSR process increases, the evaluation of CSR associations will be positive," was supported. Hypothesis 2.1 "As the evaluation of CA associations is positive, satisfaction with the firm will increase," was supported. Hypothesis 2.1 "As the evaluation of CSR associations is positive, satisfaction with the firm will increase," was supported. Hypothesis 3 "As satisfaction with the firm increases, revisit intentions with the firm will increase," was supported. Conclusions - This research is the first to study the relationship between customer participation in CSR process, CSR, and consumer reactions. This research also contributes to customer participation and corporate social responsibility literature by suggesting customer participation as an antecedent and empirically demonstrating the positive relationships between the constructs. The findings of this research may offer managerial implications for marketing practitioners. When performing corporate social initiatives, it is better to let the customer participate in the process which leads to higher corporate ability associations and corporate social responsibility associations, also higher satisfaction and revisit intentions. Our results provide useful information to practioners that spontaneous participation of consumers makes CSR initiatives effective and successful. Limitations and ideas for further research remain in this research. For example, our focus on the logic was cognitive evaluations(e.g. corporate associations) but affective dimensions might be considered since recent researches are investigating the relationship between customer participation and affective reaction as a response. Despite the limitations, this research have unique and applicable implications for academics and practitioners.

O2O(Online-to-Offline) commerce, a kind of multi-channel, is used in various industries such as accommodation, food and beverage, transportation, and real estate. The O2O commerce, a channel of integrating online and offline, overcomes the limitations of traditional online commerce, where a customer made a purchase decision without direct experience. Despite this advantage of O2O, if the online-offline channel is not effectively linked, customer's complaints would occur due to service failure. This study, with regard to O2O service failure circumstances, intends to investigate the effect of customer's perceived justice on their emotional response, recovery satisfaction, followed by intention to repurchase. Perceived justice in this study is composed of distributive justice, interactional justice, and procedural justice. Furthermore, this study explores the moderation effect of O2O industry types in the relationship between perceived justice and emotion. An O2O industry type is classified into accommodation, food and beverage, and transportation. A hypothesized research model was empirically tested using a structural equation model. The current study collected 433 questionnaires and the target respondents are customers who have experienced service failure in O2O commerce. The empirical results showed that O2O commerce more effectively conducts service recovery strategy and causes positive customer response by integrating online and offline channel. One of the ultimate purposes of O2O service providers is to reduce the likelihood of service failures and to recover more quickly and efficiently by linking two channels rather than using a single channel. This study suggested that the O2O channel is effective in influencing customer satisfaction and loyalty by inducing customer's positive emotions in recovering service failure.
