The purpose of this article is to propose the functions of the School Library Support Center of the Ulsan Metropolitan City. The findings are based on the 2009 and 2010 statistics of the school libraries in the Ulsan Metropolitan City, and a questionnaire survey that was conducted for teacher librarians and the class teachers who manage their school libraries without a Library Science degree. The proposed tasks of the School Library Support Center fall into two categories: administrative and practical. Administrative tasks include assigning teacher librarians to schools, expanding library resources, and establishing an integrated supervision system for both school libraries and student reading programs. Practical tasks include developing educational programs, informing library program providers to school, and public relations programs about the Center's services.

The aim of this study is to analyze the transition of the building of Daegu City Library during the Japanese Colonial Period. To do this, the articles of newspaper and periodicals, books, official documents, official gazettes, statistics, publications of official history of Daegu City Library and research papers were widely collected and cross-checked with each others. As the result of this study, the precedent researches and official history publications related to Daegu City Library had some important errors including the date of the municipal ordinance for Daegu City Library, the first building of Daegu City Library and the date of the breaking-ground, completion and opening for the new building. It is assumed that these errors were generated from the shortage of bibliographic information and full-text databases at those time. At the end of this study, additional research about the history of Daegu City libraries during the Japanese Colonial Period were suggested.

The skew-t distribution is an attractive family of asymmetrical heavy-tailed densities that includes the normal, skew-normal and Student's-t distributions as special cases. In this work, we propose an EM-type algorithm for computing the maximum likelihood estimates for skew-t linear regression models with censored response. In contrast with previous proposals, this algorithm uses analytical expressions at the E-step, as opposed to Monte Carlo simulations. These expressions rely on formulas for the mean and variance of a truncated skew-t distribution, and can be computed using the R library MomTrunc. The standard errors, the prediction of unobserved values of the response and the log-likelihood function are obtained as a by-product. The proposed methodology is illustrated through the analyses of simulated and a real data application on Letter-Name Fluency test in Peruvian students.

The goal of this study was to examine ways to improve the quality of databases of the Korean National Assembly Digital Library(KNADL). In order to achieve the goal, we first designed an assessment tool that could measure the quality of the 'contents,' the 'service,' and the 'system' of the KNADL's databases. Each of the three categories also had sub-categories-i.e., eight sub-categories for 'contents'(e.g., accuracy, recency, ${\cdots}$), seven sub-categories for 'service'(e.g., convenience for request, rapid response, ${\cdots}$), and seven sub-categories for 'system'(e.g., usability, response time, ${\cdots}$). We thenconducted a survey using the assessment tool we developed and gathered a total of 270 responses from users of KNADL's databases. We used Excel and PASW Statistics 18 for data analysis. Each sub-category was measured by its importance and by the level of satisfaction(implemented from the DigiQUAL project). Finally, we performed an importance-satisfaction analysis(ISA) to identify what action(i.e., maintain, concentrate, low priority, and exceed) needs to be made in each sub-category. We concluded the paper with some useful suggestions for improving the quality of KNADL's databases.

The focuses and methods in Library science have been changed abreast with the development af library facilities and with the expansion and diversification of its functions. One of current trends in Library science is focussed on the social functions of library: its relations to the public, effective service for the users. and efficieniencies of the management policies, and so. on. To. deal with these issues, we need to borrow methodology from other disciplines such as management, marketing, statistics, etc. This paper is mainly concerned with how we approach to the measurement af services and thus provide tentative standard for evaluating library services. To do. this work properly, we'd better consider the users' needs and expectations. But it is not an easy work since too many factors are involved in the study of the users' needs. Users' needs and expectations are so. varying that it is difficult to find out some general and objective data. That is the reason why although many scholars have urged time after time the necessity of library's effectiveness measurement, few studies demonstrated substantial method for measuring the effectiveness of service. In this paper I propose a device for measuring service: i. e, Conjoint Analysis. Conjoint Analysis, which has originally been developed and applied in marketing research, is used to measure the priorities and preferences of purchasers on the new item. So far as Conjoint Analysis, concerning users' physical and psychological necessities, can numeralize people's needs, it may also be applied to measure service provided by nonprofit organization like library. If this approach prove to be sucessful, I hope this study to make any contribution to the appropriate direction on improving library facilities based on the result from a concret reference evaluation.

This study examines policy issues for the future development of libraries belonging to the metropolitan office of education focusing on facilities (legal basis for installation), management (dedicated department), human resources and budget. This study collected and analyzed related data using National Law Information Center and National Library Statistics System. As a result of this study, the names of the libraries performing library functions varied due to the difference of the administrative organizations of the libraries in the metropolitan education office. In addition, library policy work carried out by the library department may be excluded from policy priorities as a subsidiary task. It is analyzed that the expansion of quota of the librarian deputy director to provide the opportunity for promotion of librarians and the increase of the library input budget against the total budget are necessary.

Currently, collections with public libraries are evaluated only on the basis of simple data, such as the use volume of collections with individual libraries, and interlibrary lending (ILL) results. To promote the ILL of regional libraries and raise the use of collections, however, the evaluation of collections should be expanded from individual libraries to regional libraries. This study aims to propose user-oriented methods for evaluating the library collections within a regional library system by using four kinds of data: collection, acquisition, circulation, and ILL application data. The results of this study show that the proposed method can reveal the positions of each library within a regional library system, and also the characteristics of a library's collections and users' needs more precisely.

This study aims to look at overall adolescents' perceptions of library and reveal the relevance of search engine sources and library sources compared each elements of them and find out any related issues of perceptions of library and information use of them. The data for this study were collected through survey and analyzed descriptive statistics and correlation analysis using the data. The result shows the population users preferred search engine over library as their information search tool, and they used library as primarily a source of information for printed materials such as books and most of them don't use the library often. Also the result shows the population users tend to select information when it is easy to get and fast to access. Correlation analysis such as ${\chi}^2$ and Spearman were implemented and the result of the correlation shows that many factors of this study covered-such as comparison of information sources- have significant differences each other.

This study examined the various functions of public libraries, as well as user satisfaction and needs. We targeted 6 public libraries in the Seoul and Gyunggi area. After 280 library users were surveyed, the collected data were analyzed with an SPSS for Win 14.0 statistics program, where we used frequency, percentage, mean, T-test, One-way ANOVA, and Duncan's test. The major findings were as follows: 1) Half of the users used educational functional space, mainly in the 10-20 age group, who used it for educational purposes as a student or to prepare for getting a job. 2) There were gaps between the furniture arrangement and user preference since most libraries used a rigid system while users preferred a more flexible arrangement. 3) Space by space, public library satisfaction levels differed according to the users' gender and age. Satisfaction of the digital information room scored high, especially for users in their forties. Since public library users are diverse and require various functions, library interiors should be planned accordingly in terms of furniture arrangement and interior design. In particular, there was a gap between satisfaction by age groups, so libraries must account for community needs by considering the age group demographics of their surrounding areas.
