The purpose of this paper is to measure and analyse the relative efficiency of 17 public libraries in Daejeon metropolitan city using Data Envelopment Analysis. In this paper, total staffs, total area, total holdings are used as library inputs and total circulations, total user visits are used as library outputs. The estimated results show that libraries operate at 64.15% efficiency and only 4 libraries are relatively efficient. Inefficiency of the public libraries was due to small use of outputs compared to inputs.

This paper describes evaluation methods of serials and also introduces a case study related to the selection and evaluation of serials. A total of 1,291 titles of serials, which were subscription titles of POSTECH in the field of science and technology in 2002, were analyzed. This study employs the analysis of POSTECH SCI Article reference data to suggest the models for evaluating serials and to identify the guideline for journal selection and collection development.

Since nuclear power plants (NPPs) increasingly employ digital I&C systems, reliability evaluation for NPP software has become crucial for NPP probabilistic risk assessment. Several methods for estimating software reliability have been proposed, but there is no available tool support for those methods. To support NPP software manufacturers, we propose a reliability measurement tool for NPP software. We designed our tool to provide reliability estimation depending on available qualitative and quantitative information that users can offer. We applied the proposed tool to an industrial reactor protection system to evaluate the functionality of this tool. This tool can considerably facilitate the reliability assessment of NPP software.

Collection development policies(CDP) are becoming increasingly important to libraries of all types and sizes. The paper addresses the elements to develop a collection development policy to guide the librarians for the science and technology information resources. Instead of focusing on how well a given item fits into or supports the collection, the policy gives general guidance on the selection of information resources. The general collection development guidelines for the information resources include relevance and potential use of the information, demand for the information, ease of use of the product, subject and magnitudes, stability of the coverage of the resource, longevity of the information and evaluation mechanism.

This paper aims to develop an appropriate methodology for establishing an investment strategy for 'demonstration of artificial rainfall technology using UAV' and that include establishment of a technology classification, set of indicators for technology evaluation, suggestion of final key technology as a whole study area. It is designed to complement the latest research trend analysis results and expert committee opinions using quantitative analysis. The key indicators for technology evaluation consisted of three major items (activity, technology, marketability) and 10 detailed indicators. The AHP questionnaire was conducted to analyze the importance of indicators. As a result, it was analyzed that the attribute of the technology itself is most important, and the order of closeness to the implementation of the core function (centrality), feasibility (feasibility). Among the 16 technology groups, top investment priority groups were analyzed as ground seeding, artificial rainfall verification, spreading and diffusion of seeding material, artificial rainfall numerical modeling, and UAV sensor technology.

In the rapidly developing information technology environment, information management organizations need to effectively evaluate their digital maturity and clarify the direction of improvement to effectively respond to rapidly changing environments. This study derived weights for the digital curation maturity model developed by KISTI from the perspective of digital transformation to facilitate effective evaluation and direction setting of information management organizations. Relative importance was derived as a weight in the major and middle categories of the model through the AHP technique. Summarizing the results, when the major categories of the entire model are measured on the basis of 100 points, technology is 27 points, data is 24 points, strategy is 19 points, organization (manpower) is 16 points, and (social) influence is calculated as 14 points. In addition, weights for each subcategory were presented for each major classification based on a perfect score of 100 points. It is expected that a more objective and reasonable evaluation will be possible by applying the weights for each area derived from this study to the digital transformation maturity evaluation model.
