메타분석은 evidence-based medicine의 한가지 수단으로서 현재까지 알려진 모든 지식을 체계적으로 종합하고 평가하는 분석법을 의미한다. 인의학에서는 80년대 이후 메타분석이 보편화되어 있으나 수의학에서는 거의 찾아보기 어렵다. 본 원고에서는 메타분석법에 대한 수의학 관련 연구자들의 이해를 돕기 위하여 젖소의 요네병 (Johne's disease)을 진단하는데 사용되는 ELISA검사의 정확도에 대한 메타분석기법의 적용사례를 중심으로 설명한다.

Meta-analysis refers to the analysis of analysis. It is the statistical analysis of a large collection of analysis results from individual studies for the purpose of summarizing, integrating and interpreting the inconsistent findings. However, no meta-analysis study has been conducted in Library and Information Science in Korea. This Study introduced the characteristics, basic principles, analysis procesure, and major models of meta-analysis, reviewed meta-analysis studies in Library and Information Science, and discussed major problems in conducting meta-analysis in Library and Information Science especially in Korea.

Functions of metadata, semantic and syntatic schemas, metadata service such as registries, repositories, the optimal metadata retrieval, and several considerations of implementation of digital libraries were the research scopes of this investigation. R&D outcomes of metadata subjects in the domestic community for the past 10 years were searched and analyzed. It illustrated the major results, distinctive trends as well as some insufficient aspects to satisfy the researchers and operators of metadata system development.

Metaliteracy is a new framework that reframes information literacy. Metaliteracy is distinguished from information literacy through the intruduction of postmodernism, social constructivism and metacognition. However it has been not examined whether metaliteracy studies reflect the conceptual differences. Therefore, The purpose of the study is to observe research trends of metaliteracy on the difference from information literacy. In the study, literature reviews were conducted, and frequency analysis and knowledge network analysis(co-occurrence and bibliographic coupling) were conducted for 80 metaliteracy studies. The results of the study are as follows. As a result of co-occurrence analysis, metacognition(frequency 1st) and skills(degree centrality 1st, closeness centrality 1st, betweenness centrality 1st) appeared. Since metaliteracy criticizes skill-based information literacy, the result suggests that the concepts of information literacy and metaliteracy are mixed. On the other hand, as a result of bibliographic coupling analysis, studies with high bibliographic coupling explain the difference between information literacy and metaliteracy through metacognition.

This paper attempts to explore the use of social metadata in academic libraries. A total of 173 academic libraries were examined and analyzed. Various social metadata were reviewed, involved with users' participation and contribution. Error-reports, tagging, recommendations, ratings, reviews, comments, sharing, and community were identified that support selection, sharing and collaboration through social engagement. Suggestions drawn from the findings are offered to utilize social metadata in order to enhance users' contribution and interaction. It is hoped that this exploratory study will provide insight into the use of social metadata in academic libraries.

The purpose of this study was to investigate the effects of problem solving activities of STEAM program on metacognition of middle school students. The subject was 63 middle school students. This study was designed single group pre-posttest. A single-group t-test was performed for analyzing difference between the pre-post test on metacognition. In the result of this study, there was significant difference between pretest and posttest on middle school students' metacognition. Also there was significant difference on metacognitive knowledge and metacognitive regulation. The analysis on the subelements of metacognition showed significant difference between pretest and posttest. The multiple regression analysis to investigate the relation of sub-elements of metacognition was performed in this study. The result of the analysis showed high explanatory power among metacognition subelements. This result suggests that the problem solving activities of STEAM program can have a positive effect in promoting metacognition. of the learner.

The purpose of this study is to examine semantic interoperability in terms of metadata elements and content designation in context of digital libraries. This study analyzed 78 digital libraries implemented using Greenstone application with respect to metadata elements and their content designation. Using crosswalks of digital libraries' metadata elements, and comparisons of content designation in elements. this study identifies three aspects which can impact semantic interoperability. First, there were less than 25% core metadata elements even within homogeneous information communities. Second, discrepancy exists between element names and their usage. Third, different levels were identified when assigning content to designated elements in terms of integrity and completeness.

Recently the domestic construction companies have been occurred to the various demand of information. Also information quantity is increasing. But using information have been stated in low why large information quantity. The other side, the various Metadata have been proposing in the many field for an effective search and an application. So the Metadata for using construction information must be built. In this study, we have founded information of construction companies, present condition of information, concept of Metadata and recent report. And we have presented the Metadata system model and building process of information system. We have analyzed the Metadata element of construction. This study is the foundation for the Metadata using system.
