The purpose of this study is to identify what are the common characteristics which enable the information management offices of research institutes to provide information services with their companies in effective ways, and furthur, in other to clarify what factors helf the improvement of effectiveness of information services. I have made on-the-spot investigations for the confirmation of present conditions of information service units of research institutes, their statistic data, and their managerial state. I have restricted my research to 36 information service units, as research targets, which are located in Changwon, Choongchong, and Kyongin areas as the reason mentioned in the introduction, and from their research data they keep, I have classified the top 10 information service units as Group A which show the most frequent use or application frequency of research data per a researcher, where as the lowerest 10 information service units are classified as Group B by the same evaluation of application frequency of their data. Then, the result of the comparision between Group A which provide high information services in effective ways and Group B which provide low information services with poor management leads me to identify the following characteristics in terms of the analyses of utilization of the data they process: 1. Those information service units in Group A have more volumes of books and information data, and annual increasing rates of books and informations are higher than those of Group B. 2. The regulations of book circulation in Group A are prescribed for the benefits of users, and if a long-term loan is not permitted, they are allowed to borrow more books at a time than in Group B. 3. The proportion of librarians to researchers is high, the librarians' career is long and their professional education background (the rate of librarians who majored in library science and information) is high In Group A. 4. Most of the directors of information service units are those who majored library science and information, and for the most part, librarians are promoted to the directors of information service units in Group A. 5. The information service units are managed directly under the directors of research institutes in their organization in Group A. 6. The information service units offer an education for information utilization to researchers as one of their managerial programs, and the contents of education are diverse, rich and informative in Group A. 7. The kinds of informations are various in Group A such as, SDI, prompt reports of contents of new informations, circulation of newly published publications, translation service, information analyses, critical reviews, etc. 8. The information service units in Group A have joined various cooperative systems which are aimed at cooperation, co-ownership of resources and informations. These findings lead me to argue that the hypothesis suggested in the introduction of this thesis has been proved without exception.

A smart tourism chatbot is needed as a user interface to efficiently provide smart tourism services such as recommended travel products, tourist information, my travel itinerary, and tour guide service to tourists. We have been developed a smart tourism app and a smart tourism information system that provide smart tourism services to tourists. We also developed a smart tourism chatbot service consisting of khaiii morpheme analyzer, rule-based intention classification, and tourism information knowledge base using Neo4j graph database. In this paper, we develop the Korean and English smart tourism Name Entity (NE) datasets required for the development of the NER model using the pre-trained language models (PLMs) for the smart tourism chatbot system. We create the tourism information NER datasets by collecting source data through smart tourism app, visitJeju web of Jeju Tourism Organization (JTO), and web search, and preprocessing it using Korean and English tourism information Name Entity dictionaries. We perform training on the KoBERT-CRF NER model using the developed Korean and English tourism information NER datasets. The weight-averaged precision, recall, and f1 scores are 0.94, 0.92 and 0.94 on Korean and English tourism information NER datasets.

In my paper, an evaluation method on naturalness and urbanness characterizations of animation image is proposed. In contrast to the prior works, we intend to give the exact degree of naturalness and urbanness by combining the low-level visual feature-based schemes with the biological visual schemes. In our method, four descriptors are extracted and pseudoinverse is adopted. By this method, we can experiment on the exact degree of naturalness and urbanness with satisfactory results.

This research is to understand customer satisfaction with virtual fitting based on a 3D body scanner and avatars as well as differences between avatars and the 'real me'. To this end, this research examined Korean college students to facilitate 3D body scanning, avatar generation and surveys. The author used 3D body scan data with direct measurements to identify differences between the 3D body scan data-based 'my avatar' and 'real me' in the virtual dress fitting system. The survey results on 'the level of customer awareness on 3D body scanner' found that the majority of both genders did not know about it and indicated a lower usability to incorporate IT technology into the fashion industry. The question in the 3D body scanning and avatar found an affirmative attitude. Satisfaction levels on the 3D avatars' similarity with 'own body' and garment fitting were positive and indicated a need for further technological improvements to express the avatars identical to customers' own body. More research is necessary for the accuracy of sizes for 3D body scanning that measure body sizes while wearing clothes. Avatars based on such datamay be less similar to 'own body' and cause customer dissatisfaction. Thus, further technology development is required to narrow gaps using data to make avatars that provide more accurate virtual fitting simulation services to customers.

Location-Based Services(LBS) give rise to location-dependent queries of which results depend on the positions of moving objects. Because positions of moving objects change continuously, indexes of moving object must perform update operations frequently for keeping the changed position information. Existing spatial index (Grid File, R-Tree, KDB-tree etc.) proposed as index structure to search static data effectively. There are not suitable for index technique of moving object database that position data is changed continuously. In this paper, I propose a dynamic hashing index that insertion/delete costs are low. The dynamic hashing structure is that apply dynamic hashing techniques to combine a hash and a tree to a spatial index. The results of my extensive experiments show the dynamic hashing index outperforms the $R^$ $R^*$-tree and the fixed grid.
