The existing studies of a dialogue system can be classified into two major parts. One is a study for a practical system, and the other is a study to understand a principal of dialogue phenomena. The former focuses on robustness in real environment for dialogue systems. However, it cannot guarantee its performance in complicated dialogue environment. The latter has studied as the plan-based model typically. It has strong points that it can reflect complex dialogue phenomena and can infer user's intention in various situations. However, an initial design of this model is so complicated, and it is difficult for this model to be extended to the interaction model for response generation in a practical dialogue system. This paper proposes a new dialogue modeling using plan recognition and a discourse stark to effectively generate response in a practical dialogue system.

We have seen a lot of developments on computer application areas with the wide spread use of computers and the rapid growth of communication network. It is necessary to use a cryptographic technique for electronic voting, but, at present, despite of its importance electronic voting protocols so far have many shortcomings. In this paper, with the assumption of a trustable voting centers we propose a large-scale and practical electronic voting protocol satisfying protocol requirements, such as secureness, fairness, privacy of voter and correctness. Voters are able to get a vote without revealing their voted information by using the blinding technique. We can find the injustice between a voter and the tallier by using undeniable challenge and responsible protocol. Also, we proposes a secure protocol that compensates a integrity of electronic voting and protects a privacy of voter from outer attacks as using a anonymity of voter.

The concept of customer satisfaction is very important issue in the service firms. All service firms should delight theirs customers? Which service contexts creating customer delight results in better positive performance? This study is to examine the moderating effect of service type on the customer delight-behavioral intention relationship. Data from consumers across two distinct service contexts (retail banks and upscale restaurants) were obtained. Using the multiple moderating regression analysis, the proposed hypotheses in this study were tested. The results reveal that customer delight had a greater positive impact on both revisit and referral intention in the hedonic service than the utilitarian service. This study suggests specific service contexts where customer delight strategies generate better desirable results. The customer delight strategy is able to be applied in both hedonic and utilitarian services, but it is more effective to lead customer loyalty in the hedonic service than utilitarian services. Service firms need a strategic approach to customer satisfaction strategies. This study provide strategic implications for service firms to efficiently manage and allocate resources, and can help them in making decisions about establishing and implementing customer satisfaction strategies.

With the rapid development of mobile communication tools, customers are using SNS as a major information tool. SNS can provide information to a small number of customers as well as people around them, with information about a product or service that a small number of customers know through experience. With these characteristics, dessert cafes are being used as a major marketing tool for online websites and mobile phones using SNS. Therefore, in this study, theoretical considerations about e-WOM quality, perceived value, and visit intention were performed. The effect of e-WOM quality of dessert cafe on perceived value was analyzed and the effect of perceived value on visit intention was analyzed. Based on these results, I would like to suggest theoretical implications and practical implications for online marketing of dessert cafes. This study was conducted to survey the customers who have visited dessert cafe through oral communication within the last 6 months. The survey was conducted from September 4, 2018 to September 18, 2018, and was used for the analysis of 317 additional items. The research hypotheses between the e-WOM quality of the dessert cafe and the utilitarian value, hedonic value, and visiting intention were used the structural equation model(SEM). First, neutrality and interactivity have a significant effect on utilitarian value, but consensus and vividness have not significant effect. Second, It was found that the consensus, vividness, and neutrality had a significant effect on the hedonic value but interactivity was not found to have a significant effect. Third, hedonic value has a significant effect on visit intention, but utilitarian value has not significant effect. As a result, online e-WOM quality management is important.

This study attempts to reorganize the knowledge classification system for the research fields and majors in education by designing a new classification schedule. Content analysis of the majors and curriculums in the universities and major areas of the academic professors in Korea, and the comparison with the various headings in several classification systems for research fields were carried out. Based upon the comparison with library classification systems and reviews and opinions of subject specialists in major disciplines, finally, a knowledge classification system composed of three parts - schedules, tables and a relative index - was presented. The proposed classification scheme was tested for classifying the research projects listed in the 1998 catalog of the academic research funded by Korea Research Foundation. Also, several ways for developing a more useful knowledge classification scheme to organize disciplinary information effectively and to encourage interdisciplinary research were suggested.

Structures of stories, paragraphs, and sentences and inferences applied to indexing and searching were studied to construct the full-text and sentence retrieval system for storytelling. The system designed the database of stories, paragraphs, and sentences and the knowledge-base of inference rules to aid to write the story. The Knowledge-base comprised the files of story frames, paragraph scripts, and sentence logics made by mark-up languages like SWRL etc. able to operate in semantic web. It is necessary to establish more precise indexing language represented the sentences and to create a mark-up languages able to construct more accurate inference rules.
