Nation-wide support is being strengthened to vitalize pre-entrepreneur and startup initiatives. However, it is found that they have been suffering from the lack of necessary information in preparation for the start-up operation. In order to support more proactive and robust start-up process in aspect of contents or service, it is necessary to carefully analyze their information needs and information seeking behaviors. Information seeking behavior analysis is a method for improving information services in accordance with the information needs of the information service users in libraries and information service institutes. This study analyzed information seeking behaviors of pre-entrepreneur and startup. Focus-group interview as the representative method of exploring information seeking behaviors was conducted. Content analysis was introduced to search the business-establishing process, information-seeking status, and utilization level of startup-related information resources and their perception. It is expected that contents and services for pre-entrepreneur and startup would be improved by reflecting their information seeking behaviors based on the results of this study.

This research was conducted to analyze the actual condition of data related to Korea shown in the catalog of 15 countries. This study was to compare the subject characteristics of Korea-related subject heading, record collection, and the characteristics of several subject heading, which has been a major issue. The results are as follows. To begin with, Korea-related record in most other national libraries runs absolutely short except for some countries like United States. Korea-related record is generally 2 to 3 times less than Japan related record. Second, referring to the subject distribution in sub criteria of Korea-related record, subject related to 'history' and 'economy' is shown in the highest rate. Considering that 'Korean war' shows the highest rate in Italy and Canada, we can consider that this may cause the distortion of the perception of Korea. Third, in the case of Korea-related record, the record of South Korea is 1.5 to 5 times more than that of North Korea, except for some countries like United States. Forth, regarding the subject headings, the terms such as 'Taekwondo', 'Kimchi', 'Tok-do', 'Tong-hae' have different meanings in different countries. However, these terms agree to LCSH in most countries except for neighboring countries. Fifth, in case of China and Japan, the subject headings in reference to political and historical position are raising some problems.

This study is the most important component in establishing the court library as the best legal library in Korea responsible for professional legal services. A perception survey was conducted on the target. As a result, first, looking at the collection direction based on the needs of general users, in the case of collection types, preference in the order of books, electronic materials, and non-books should be considered. It seems to be necessary to plan a collection development policy reflecting the high preference for books. In addition, in the non-books section, the preference for non-book materials in the form of video rather than audio is much higher, and in the case of language, domestic books should be collected mainly. Second, looking at the collection direction based on the needs of experts, the satisfaction of experts is generally low, so it seems that a collection development policy should be established to improve this. As for the type of information source, preference was shown in the order of electronic materials, books, and non-books. There is a need. The future collection direction should be based on the preference shown in the order of procedural law, specialized field, basic substantive law, and legal series. Also, when collecting the same book, electronic form of legal data should be considered rather than printed. In addition, it is necessary to collect collections mainly from domestic books, and then, it is expected that the scope of collection should be expanded to prioritize English and American books, Japanese books, and German books.

As open source can reduce costs and apply to various fields rapidly, many countries have actively adopted open source. However, geo-spatial open source in Korea is not actively promoted yet comparing to other countries having similar infra environments. In this study, we analyzed the perception of geo-spatial open source, utilization status, the development possibility and future direction using questionnaire survey completed by experts dealing with spatial information. The survey result shows that many experts have experiences of using geo-spatial open source but they got a lack of understanding about open source license or regulations and only a few people got professional training. Insufficient references, the difficulty of maintenance, lack of support and low technical reliability have hindered the adoption of geo-spatial open source. Only some part of geo-spatial open source software or libraries in some field have been used in the country. However, many researchers rate highly development potential and plan to use geo-spatial open source soon. If user's convenience, reference materials, technical trust and policy support are improved, open source field for spatial information will be developed greatly in the future.

This study investigated the overall perceptions of pre-service school librarian teacher on the current education practicum through semi-structured in-depth interviews and suggested improvements to the educational practicum system. For this purpose, interview data were collected from 28 pre-service school librarian teacher (6 teachers' colleges, 14 taking teaching qualification courses, and 8 graduate school of education) who participated in educational practicum in school libraries, and a research method that combines qualitative analysis techniques with text network analysis was applied. The results of the study showed that pre-service school librarian teacher believe that educational practicum can prepare them for various field experiences and cultivate their ability to cope with situations they will encounter in the future. Through qualitative inquiry, we were able to identify their perceptions of school field practicum as a whole, their perceptions of the school field practicum, and their perceptions of educational service activities. Based on this, to improve the current problems of educational practice, we suggested expanding the period of school internship program, distributing the time, establishing a full-time practice system, having continuous discussions with field teachers, and developing a systematic school field practicum.

Despite the growth in public concern about health information, the ratio of users who can search for accurate and reliable health information sources has been found to be quite low. Public libraries, as the best contact point to general users, must provide training programs for improving health literacy so that users will have the ability to search and analyze health information, judge the accuracy and reliability of resources, and make informed health-related decisions. This study developed a health information literacy education program suitable for Korean public library users. The effectiveness of the training was measured after administering the program, and necessary improvements were identified. As a result, this study found the education program had the following effects: improved public library users' familiarity with CHI-related terms, improved users' ability to find CHI-related information resources on the Internet, and significantly improved knowledge about health-related websites and information sources. In addition, users expressed interest in seminars on a variety of health information sources in the public library and asked that CHI-related education be included in the library's regular programming. However, this research represented the first time CHI-related education for public library users was performed in Korea, and therefore many limitations were present in the education instructor, the diversity of subjects, and the methodology. Development of more advanced CHI-related education programs for users is still required.

This study investigates the credibility judgements of information by tweens using digital media and information. Particularly, the study focused on tweens' perception of internet research and information use and on their credibility judgement of source and message, internet service providers, and on consulting with others for their credibility judgement. The survey methodology was used to collect data from grade 5 and 6 students in two elementary schools whose parents are likely in middle and upper class. 336 valid questionnaires were collected among 400. Descriptive statistics, factor analysis, and t-test were used to analyze the data collected using SPSS 25. Findings suggested that tweens understood the importance of using smart media and computers, that they used Youtube, Naver, Kakao talk, Naver JisikIN much in sequence, and that they believed the Internet research was easy and fun. Using exploratory factor analysis, the survey questions for credibility judgement were classified into three factors: Internet service providers, sources and information, and consulting with others. Tweens used sources and information credibility, consulting with others credibility, Internet service providers credibility in sequence. However, it was interesting to find that there were greater deviation in answers on knowing how to find out the cognitive authority of the authors and on the importance of using current information. This study suggests the critical need for tweens' credibility judgement research for promoting critical thinking skills as well as for proactive educational practices in schools and libraries on information literacy.

Among the approaches to image database management, content-based image retrieval (CBIR) is viewed as having the best support for effective searching and browsing of large digital image libraries. Typical CBIR systems allow a user to provide a query image, from which low-level features are extracted and used to find 'similar' images in a database. However, there exists the semantic gap between human visual perception and low-level representations. An effective methodology for overcoming this semantic gap involves relevance feedback to perform feature re-weighting. Current approaches to feature re-weighting require the number of components for a feature representation to be the same for every image in consideration. Following this assumption, they map each component to an axis in the n-dimensional space, which we call the metric space; likewise the feature representation is stored in a fixed-length vector. However, with the emergence of features that do not have a fixed number of components in their representation, existing feature re-weighting approaches are invalidated. In this paper we propose a feature re-weighting technique that supports features regardless of whether or not they can be mapped into a metric space. Our approach analyses the feature distances calculated between the query image and the images in the database. Two-sided confidence intervals are used with the distances to obtain the information for feature re-weighting. There is no restriction on how the distances are calculated for each feature. This provides freedom for how feature representations are structured, i.e. there is no requirement for features to be represented in fixed-length vectors or metric space. Our experimental results show the effectiveness of our approach and in a comparison with other work, we can see how it outperforms previous work.

The purpose of this study is to analyze the health information use experience of middle-aged people in their 40s and 50s and to observe and analyze their health information search behaviors according to health consciousness and health information orientation. This study uses Information Foraging Theory with the concept of information scents which leads users to detect and collect cues in information searching. Types and contents of information cues that middle-aged people use when searching for health information were investigated. Also, how their health consciousness and health information orientation affected using information cues were analyzed. Three methods of research were used; (1) pre-interviews, (2) search experiments, and (3) post-interviews. Thirty-two middle-aged people participated in the study. Their performance on health information searching was recorded and referred to in the post-interviews using a think-aloud protocol. Findings presented that middle-aged people's health consciousness and health information orientation affected the perception of information scents in health information search; those with high health consciousness and health information orientation consider the text made by the government office the most critical information cues. We believe findings from this study could be used for public libraries or non-profit institutions to understand middle-aged people's health information behaviors to design education programs for information retrieval considering users' health consciousness and health information orientation. Findings could also contribute to Internet portal site or health-related web site designers developing strategies for middle-aged users to access health information effectively.

The free viewpoint video delivers an active contents where users can see the images rendered from the viewpoints chosen by them. Its applications are found in broad areas, especially museum tour, entertainment and so forth. As a new free-viewpoint application, this paper presents a stereoscopic free-viewpoint TIP (Tour Into Picture) where users can navigate the inside of a single image controlling a virtual camera and utilizing depth data. Unlike conventional TIP methods providing 2D image or video, our proposed method can provide users with 3D stereoscopic and free-viewpoint contents. Navigating a picture with stereoscopic viewing can deliver more realistic and immersive perception. The method uses semi-automatic processing to make foreground mask, background image, and depth map. The second step is to navigate the single picture and to obtain rendered images by perspective projection. For the free-viewpoint viewing, a virtual camera whose operations include translation, rotation, look-around, and zooming is operated. In experiments, the proposed method was tested eth 'Danopungjun' that is one of famous paintings made in Chosun Dynasty. The free-viewpoint software is developed based on MFC Visual C++ and OpenGL libraries.
