While a number of studies have been conducted on the multimedia rooms in academic libraries, they have limitations both in the research scope and in the data analysis methods. The principal limitations are: (1) Lack of investigation on the variation in user satisfaction by users' major areas and utilization behaviors; (2) Insufficiency of examining the variation in user satisfaction with diverse library areas; (3) Lack of consideration of service providers' opinions. Accordingly, this study aimed to examine the follows: (1) investigating how users' major fields and utilization behaviors affect user satisfaction; (2) determining the relationships between the area satisfaction factors and satisfaction in general; and (3) discovering what to improve, as indicated by users and service providers. On the basis of the results, the suggestions relate to the improvements of the followings: (1) the existing system; (2) equipments and facilities; (3) resources; (4) user education; and (5) administrative and legal support.

The purpose of this study is to investigate what level of difference in precision would be significantly perceived by a human user of an information retrieval system. Not many researches have been conducted with regards to this issue in information retrieval field. Despite the non-significant results, there were several interesting findings in recognizing different levels of precision rates. The correctness of relevance task had little to do with the taken time for the task. In addition, the strong relationship between the subjects' topic familiarity and rate of correct judgments is one of the most interesting results in this study. It turned out that the subjects have more difficulty in a situation they have to judge between the two lists having more non-relevant documents than in a situation they do between the lists haying more relevant documents. Finally, the serious influence from the first top N documents in a list for relevance judgment task has been confirmed.

This paper used the network analysis method to analyse a variety of attributes of searcher's search behaviors which was appeared on search access log data. The results of this research are as follows. First, the structure of network represented depending on the similarity of the query that user had inputed. Second, we can find out the particular searchers who occupied in the central position in the network. Third, it showed that some query were shared with ego-searcher and alter searchers. Fourth, the total number of searchers can be divided into some sub-groups through the clustering analysis. The study reveals a new recommendation algorithm of associated searchers and search query through the social network analysis, and it will be capable of utilization.

As coming Senior-Shift age, senior users are regarded as one of the importance user groups in the library. This study is to find the usage patterns and needs of libraries and digital libraries by 152 seniors and to compare with young-old age (baby boom generation) and elderly age. As a result, total seniors visited regularly and preferred political & social, religion & philosophy, and history & geography. While the baby boom generation are using the economy & finance, art & culture compared to the older. And the baby boom generation visit for self-development and the older visit for leisure purposes. Secondly, If the search fails, the baby boomers control the results themselves, while the older is more turn to the librarians. It can be described as the need for a librarian exclusively responsible for the senior. Thirdly, senior have difficulties in access and use of search aided tools or functions. Therefore, this study suggested that it is necessary to build an intuitive interface using the help and menu descriptions for senior who have poor access to convenience and define functions.

The study proposed an electronic journal retrieval model to be used to improve the retrieval efficiency of e-journals. To do this, firstly, we reviewed the literature on users' information behavior and on ERM (Electronic Resource Management) systems. Secondly, we conducted an e-mail survey of 96 participants (professors and graduate students) to find out about their information behavior on how to access, use and evaluate electronic resources as well as scientific information. Thirdly, we administered case studies on two ERMSs, Ex Libris' Verde and Innovative's Millennium. The proposed model will be operated within ERM systems and it enables to the supply of both system- and user-based services by combining taxonomy-based ERM systems with tag folksonomy. The model is unique in that it includes not only the automatic tagging functions that can be performed using log files but also the tag management functions including grouping similar or related tags.

This paper is divided into two parts. The first part elaborates on four Information Retrieval (IR) models: a traditional IR model and three more recent, user-oriented models of It interaction presented by Belkin, Ingwersen, and Saracevic. The strengths and limitations of each model are discussed. The second part, based on an analysis of the previous models, presents the author's interactive model, namely, the Iceberg Model. The rationales that are given to explain the design of this model are associated with the following: a greater specificity of system attributes; more concrete interplays among different components of IR interaction; and, the increased role of the Human Information Intermediary (HII). In sum, the new model presents a framework that can evolve in varying information-seeking contexts.

The purpose of this study is to examine the functions and features of SearchWorks developed as the Next Generation Library Catalog by Stanford University Libraries. It was designed to fully represent the needs and search behaviors of users, with Blacklight, an open source software. Its main features are not different from those standard functions supplied by other commercial packages of Next Generation Library Catalogs, and its continuing improvement and changes, including the addition and expansion of more useful functions and the removal of unnecessary ones, have been observed since the introduction of a beta version in 2010.

The purpose of this study is to present the design of search interface of mobile catalog of University libraries by identifying the current situation of search interface of mobile catalog of domestic and overseas academic libraries and users' preferences derived by survey, and reflecting the combined results. The investigation on current situation of search interface of mobile catalog of domestic University libraries was carried out by using checklist for functional assessment targeting 82 mobile catalogs. For overseas examples, contents and functional elements about 15 mobile catalog search interface of academic libraries in England and US were examined and analyzed. In addition, three domestic University libraries's mobile catalogs were selected as research targets and the survey was carried out to identify the situation of use of mobile catalog and preference on search interface.

The purpose of this study is to evaluate the quality of OPAC user interface in academic library setting, particularly on the basis of the user group's information searching behavior. Both survey and experimental methods were used for data collection. For the survey, 52 graduate students with various academic background were selected, and 8 out of 52 were chosen for the retrieval experiments using the SOLARS of the Seoul National University. The findings of this study suggest that both (unction and design of the SOLARS user interface should be improved to become a more user-friendly OPAC system.

The purpose of the study is to identify what search options are used to decide how to search on the online catalog system, and to suggest a format of the initial screen NOTIS and Dynix systems were used. Data collection was conducted in accordance with a $'2\times2'$ design. The study shows the effect on user choices of the initial men formal especially where the arrangement and breadth of search options are concerned. The availability of search options provides various users' search option selection The results of the study suggest that users can input only search term(s) on the initial screen without choice of search option Then, users may select search fields depending upon the results of searching. This method can reduce the search fail when users select wrong search option on the online catalog.
