  • This paper first reviews various techniques proposed for automatic indexing with special emphasis placed on statistical techniques. Frequency-based statistical techniques are categorized into the following three approaches for further investigation on the basis of index term selection criteria: term frequency approach, document frequency approach, and probabilistic approach. In the experimental part of this study, Pao's technique based on the Goffman's transition region formula and Harter's 2-Poisson distribution model with a measure of the potential effectiveness of index term were tested. Experimental document collection consists of 30 agriculture-related documents written in Korean. Pao's technique did not yield good result presumably due to the difference in word usage between Korean and English. However, Harter's model holds some promise for Korean document indexing because the evaluation result from this experiment was similar to that of the Harter's.

  • A more sophisticated library collection policy is required due to the changing information environment. Both traditional resources and diversified networked information resources are increasing continuously. The National Library of Korea should construct a systematic collection development policy in order to fulfill its mission. The purpose of this study is to develop a basic framework that is intended to improve the coverage of national collection. Examining previous studies and the national collection development policies of major advanced countries, a model consisting of four sub-models has been proposed. It includes hybrid collection, cooperative linking collection, collection evaluation, and a collection policy statement. Details of the sub-models and strategies are described.

  • We proposed a video summarization algorithm based on an ERP (Event Related Potentials)-based topic relevance model, a MMR (Maximal Marginal Relevance), and discriminant analysis to generate a semantically meaningful video skim. We then conducted implicit and explicit evaluations to evaluate our proposed ERP/MMR-based method. The results showed that in the implicit and explicit evaluations, the average scores of the ERP / MMR methods were statistically higher than the average score of the SBD (Shot Boundary Detection) method used as a competitive baseline, respectively. However, there was no statistically significant difference between the average score of ERP/MMR (${\lambda}=0.6$) method and that of ERP/MMR (${\lambda}=1.0$) method in both assessments.

  • This study aims to investigate the effects of emotional labor level on the level of job satisfaction and library information service provision in public libraries. The research model used emotional labor levels as an independent variable; job satisfaction and level of library information service provision as a dependent variable; and organizational culture as a control factor. The data were collected randomly from 220 librarians of public libraries in Seoul by distributing and collecting internet surveys. Reliability analysis, correlation coefficient analysis, multiple regression analysis, and regression analysis were performed using the SPSS 18.0 program. The statistic hypothesis test results of this study can be summarized as follows. First, public library librarians did not like to express their emotions to users, trying to express their emotions more positively than what they were actually feeling. Second, although librarians experience emotional labors, they feel a sense of achievement when undertaking their tasks and develop pride and happiness in their work. As librarians perceive their work professional, they overcome emotional labors, and have pride in their work. Third, although librarians experience emotional labors, a reasonable job evaluation with goals, and their relationships with colleagues would lead to accomplishment in their work. In addition, although the evaluation of employees is focused on performance, librarians improve their service if library users are satisfied with their service and the services are provided adequately.

  • The im of the present study is to introduce and develop the concept and theory of conspectus for the first time in Korea, and to propose a new evaluation model for book collection by actually applying the developed methodology to the collection of a special library dedicated to Biblical Studies. Conspectus is a standardized and objective evaluation method that classifies the main collection according to the division, category, subject, and then gives each collection ots appropriate collection level code by analyzing the classified collection in terms of three different dimensions, which are Current Collection Level(CL), Acquisition Commitment Level(AC), and Collection Goal Level(GL). To evaluate the collection of the sample library, shelflist analysis, list checking, acquisition data in ordering process by their main subject, and survey of its users have been carried out, and all of their results ahve been indicated in terms of eleven collection level codes developed by WLN Conspectus. T e collection of sample library was evaluated as '3cW' for CL, '4W' for AC, and '4W' for GL when the Conspectus methodology was applied for evaluation. This study could be utilized as an collection evaluation model for theological libraries, and become a basis to bring about more active cooperative collection development among related libraries.

  • This study reviewed the current status of low-experienced teacher librarians with less than 5 years and attempted to identify their educational needs through IPA analysis, Borich Priority Formula, and The Locus for Focus Model. A survey was conducted on low-experienced teacher librarians with less than 5 years of experience to analyze their process in the pre-service teacher training and experiences before an appointment and to identify teacher librarians instructional expertise. The results of the analysis of the study are as follows. First, there was a statistically significant difference between the importance and performance in all areas of instructional expertise of low-experienced teacher librarians. Second, 'reading education-practice progress' was recognized as a 'Keep up good work' with high importance and satisfaction, and 'library-based instruction planning, progress evaluation', 'information literacy-curriculum design', and 'digital and media literacy education-progress and evaluation' were recognized as areas of 'Concentrate here' through IPA analysis. Third, In the Borich Priority Formula, 'teaching-learning evaluation', 'teaching-learning progress', and 'teaching-learning plan' in the Library based instruction area showed the highest educational needs. Fourth, the library-based instruction was shown to the high discrepancy/high importancy area as same as the Borich Proity Formula. The results of this study can provide implications for improving the instructional expertise of teacher librarians.

  • It is essential to estimate and evaluate for user satisfaction and quality management of database system, understanding of user needs and quality characteristics. Based on ISO 25000 series, it was suggested, the first research, that 5 main quality characteristics, 21 sub quality characteristics and 48 internal quality characteristics. There are comparative significance methods of main quality characteristics, sub quality characteristics and internal quality characteristics but it is not easy to use directly quality model in database system industry field. Also, Considering time and cost in quality evaluation, it is impossible to evaluate 48 internal quality characteristics and its level of quality evaluation is not equal in accordance with integrity level of database system. By using AHP, this study presents selection method of quality characteristics in weight and possibility of application quality model.
