Academic libraries are trying to develop fully mobile web sites and mobile applications so that users can access to their services even using mobile devices. As the mobilization trends of library services increase in quantity, we need to more focus on what mobile services users want, ultimately for the growth with quality. This study seeks to explore users' needs and uses of mobile library services and then suggests solutions for improving the mobile services in academic libraries. This study conducted on and off-line surveys with 608 students from two universities, which have provided active mobile services with both a mobile web site and an application. The questionnaire was designed to elicit information on respondents' frequency of mobile library visit, the purpose of visit, the reason to use/not use, how to access to the services, the preferred types of the services, satisfaction and dissatisfaction factors, and urgently needed improvements. Based on the findings, this study discussed strategies to improve the quality of mobile services and to increase in users' visit.

Two types of key distribution protocols with user authentication are proposed for PCS(Personal Communication Service) and digital mobile communication systems. In this paper, we investigate the service procedure and security requirement for PCS. also discuss the security problems of KDPs previously proposed for digital mobile communication, and show that Park`s type II among the schemes is easily broken by an impersonation attack. Our proposed I, II are based on the modified cryptosystem of Rabin and ElGamal, and reduce the amount of computation for user authentication. Such a reduction is good solution coped with the limited capability of user terminal on PCS. As a result of making a comparison between our schemes and the previously presented schemes, we can know ours are more secure and efficient for PCS.

In comparison to the services provided by the typical information systems, the historical records from the period before the modern times require additional information services to reflect the format and content oriented peculiarities of the data. The additional services also need to be considered in light of the users' information needs. For this study, a series of literature reviews was conducted to present the specific analysis criteria for the historical information services. Based on these criteria, the domestic and foreign historical information service provision and use status was investigated. In addition, users' information needs were identified and user-based historical information service improvement suggestions were generated.

This study has been examined in information service in related aspect of its user. Also this subject is researching of information itself attribution and relationship with end user And, in information facilities of library and information center it has been studied how to develope satisfaction service for user, along with fur causing both theory and practical application. For this object it has been also reviewed theoretically through out 5 fields as below; 1) information need and using 2) information storage and retrieval 3) information property and value 4) bibliometrics and citation analysis 5) administration and management.

This study intends to implement an OPAC prototype based on FRBR(Functional Requirements for Bibliographic Records) model, which are reflected the users' information needs and search behavior. To the end, this study applies prototyping techniques that design, evaluate and improve an early sample model. Included in this study are as follows: (1) design a conceptual model of new OPACs based on the users' information needs about FRBR-based search services, (2) implement a FRBR-based prototype with WordPress 4.2 version, (3) evaluate the FRBR-based prototype from the viewpoint of users and experts(catalogers and professors). 50 college students and 6 experts participate in the final evaluation process.

The purpose of this study is to improve the classification focused on KDC 4th edition for children's materials. For the study, literature study, KDC application and user survey in 51 libraries for children were performed. Based on the results, classification for children's materials is proposed to improve in two ways: classification system itself and arrangement in the shelf. First of all, it is required to scatter the subjects that are centered on specific numbers and to allow various types, characteristics and literature genre of children's materials to be classified in KDC. KDC also should provide specific notes and classification guidelines for interdisciplinary subjects. In the shelf arrangement, it is proposed to consider the introduction of user-friendly call number and arrangement principles by ages or titles. In the end, it is necessary to compose various collections that represent users' needs, and the user education program is needed.

This study aimed to analyze users' behaviors to use mobile services of academic libraries by indirectly observing users' experiences based on their diaries. Ultimately, this study intended to contribute to the development of mobile services in academic libraries by helping academic libraries understand users and their needs of mobile services. For this, diary method was conducted with 20 students at two academic libraries. These participants should report detailed process and thoughts immediately after using mobile library services at least once a day during a week. Totally 137 diaries were collected. And then this study conducted a content analysis to figure out what information needs they had, whether or not the needs were solved, what menu they selected, and what steps and gaps they got. In addition, on the basis of the findings, this study suggested further steps for improving mobile services at academic libraries.

To effectively cope with new and different types of disasters, it is very important to communicate and update disaster information to the public quickly and efficiently. SNS enables rapid spread of information and continuous exposure. SNS enables two-way communication by directly communicating with users. SNS complements the shortcomings of mass media, and increases the effectiveness of disaster management work. This study analyzed user awareness and requirements to derive effective methods of SNS operation of disaster management institutions. For this purpose, a user survey was conducted to identify the types of information that are highly user-interested and to select information items suitable for SNS services. Through this, we suggest ways to improve the SNS disaster record information service of the disaster management institution.

최근 도서관에서는 실업률 증가와 지역사회 정신보건 문제 등 총체적인 사회적 현상과 맞물려서 도서관 서비스에 불만을 품거나 이상행동을 하는 이용자들이 도서관으로 유입되면서 많은 문제행동을 일으키고 있다. 일부 이용자의 문제행동은 다른 이용자의 이용만족에 있어서 가장 중요한 역할을 하는 도서관직원에게 부정적 영향을 미치고, 이는 결국 서비스의 불만족과 이로 인한 도서관 조직에 악영향을 끼치며 전반적인 도서관 서비스의 질적 저하를 유발하는 중요한 요인으로 작용하고 있다. 본 연구는 도서관서비스에 대한 이용자 만족도를 제고하고, 친절하고 품위 있는 공공서비스 문화의 선진화를 촉진하기 위여 국가 및 공공도서관 직원을 대상으로 도서관 응대서비스 문제점 및 문제이용자 현황과 응대서비스 매뉴얼 개발에 관련된 요구사항을 분석하여 일반이용자 및 문제이용자 응대서비스 매뉴얼을 개발하였다.

The main purpose of this research is to look into not only how users evaluate two major databases(BIST and SATURN) of the scientific and technical literature in Korea, but also what users expect from scientific and technical information services in general. The result of the user evaluation shows that there is a very little difference between two databases in database quality. It was found that BIST is better than SATURN in terms of accuracy, customer support, searching capability, and currency, whereas SATURN is preferred to BIST for completeness and the average number of retrieved items. User expectation for scientific and technical information is also investigated by surveying its user community. Among three user groups, there is notable disagreement in language uses to search non-korean literature. Each group also shows different demands for translation of original literature. This study attempted to evaluate the quality of the scientific and technical information (BIST and SATURN) and simultaneously to investigate users demands in general. By doing so, the specificity implied in quality evaluation of specific information services as well as the generalization of the users behaviors in scientific and technical community were accommodated in this study.
