This study was a quasi-experimental study to test a research question: Is the school library-assisted instruction effective in enhancing students' academic achievement? To solve the research question, 14 hours of school library-assisted instruction and traditional lecture were carried out to 164 9th grade middle school female students(82 of experimental group, 82 of control group). SPSS 12.0 was used for statistical analysis of frequency analysis, $x^2$-test, and t-test. The results showed that there was a statistically significant difference between the pre-test and the post-test in the total academic achievement scores of both experiment group and comparison group. There was a statistically significant difference between the pre-test and the post-test in paper and pencil test scores for comparison group. There were statistically significant differences between the pre-test and the post-test both in paper and pencil test scores and performance assessment for two groups. But there were no statistically significant differences between the experiment group and the comparison group in post-test pre-test gap of total academic achievement, paper and pencil test, and performance assessment scores.

Based on the Everyday Information Seeking Behavior Theory, this study investigates information activities and library experience of 66 elderly or people with disabilities in Autonomous District A. In addition, this study analyzes contextual circumstances of daily information activities through in-depth interviews with a subset of 11 people. Although community welfare centers provide basic welfare, the elderly and people with disabilities seek to learn and socialize in cultural welfare centers, particularly in libraries. This study shows that libraries can fulfill their top three of Maslow's hierarchy of needs: Self-Actualization, Esteem, and Love and Belonging. Specifically, digital literacy education has been identified to be highly demanded. They seek to distinguish correct online information and to socialize using digital technologies in this contactless society. This study proposes a detailed plan for public libraries to offer cultural and information welfare in order to reduce the information gap within the local communities.

To obtain good summarization algorithms, we need first understand how people summarize videos. 'Semantic gap' refers to the gap between semantics implied in video summarization algorithms and what people actually infer from watching videos. We hypothesized that ERP responses to real time videos will show either N400 effects to topic-irrelevant shots in the 300∼500ms time-range after stimulus on-set or P600 effects to topic-relevant shots in the 500∼700ms time range. We recruited 32 participants in the EEG experiment, asking them to focus on the topic of short videos and to memorize relevant shots to the topic of the video. After analysing real time videos based on the participants' rating information, we obtained the following t-test result, showing N400 effects on PF1, F7, F3, C3, Cz, T7, and FT7 positions on the left and central hemisphere, and P600 effects on PF1, C3, Cz, and FCz on the left and central hemisphere and C4, FC4, P8, and TP8 on the right. A further 3-way MANOVA test with repeated measures of topic-relevance, hemisphere, and electrode positions showed significant interaction effects, implying that the left hemisphere at central, frontal, and pre-frontal positions were sensitive in detecting topic-relevant shots while watching real time videos.

From 1990s the Ministry of Education and KERIS have developed nationwide academic resource sharing and service system based on universities, and have contributed to bridge the gap of information and to facilitate resource sharing between universities. Meanwhile, in Japan which starts 15 years earlier than us, the Ministry of Education and NII built nationwide academic resource sharing and service system with starting on the project of university holding resource sharing and until now have shown similar aspect of development like us. But lately, since information environment has been changing rapidly, Japan try to find new paradigm which goes around electronic resources management substitute for physical resources and open access based academic communication, institutional repository which disseminate university's research output to the outside world. This study compare academic resource sharing and service system between Japan and Korea and try to suggest for Korean academic resource sharing and service system development. In Korea, firstly we should try to replacing published resources management system to electronic resources', secondly, reorganizing oversea's resource sharing and service system, thirdly, reactivating institutional repository toward open access, finally, unification of distracted driving force.

The aim of this paper is to analyze the trend of the research product of Korea and Japan about each other in 20th century. The author analyzed the published year, main period, and author of the research product of history. So she explored the resent state, size, history, and gap of the research product between Korea and Japan. The study about Japan history in Korea began after 1945. However, the study about Korean history in Japan began after 1875. So the study about Japan history in Korea is falling behind Japan for 70 years. As a result, research including the amount of research the number of researchers, the diversity of the minor subject is 1/3 of that conducted by Japanese Scholars.

This study attempts at the engraving place of wood-printing plates held in the Haein Temple(해인사), which were famous for playing the significant role in the understanding of publishing activities of both the Koryo and Choson Dynasty. Following the common way the bibliographic elements of the books were analyzed namely according to the publication place and the publisher. The findings derived from the analysis are summarized as follows; In the Haeinsa the wood-printing plates books are preserved moved from 17 temples such as Bongso-Sa(봉서사), Hago-Sa(하고사), Soksuam(석수암), Inhung-Sa(인흥사), Wonkwang-Sa(월광사), Sinha-Sa(신하사), Gunsyaeng-Sa(군생사), Jangsu-Sa(장수사), Yongtong-Sa(영통사), Wonjok-Sa(원적사), Unjin(은진) SSanggye-Sa(쌍계사), Songsan(성산) SSanggye-Sa(쌍계사), Hungyul-Sa(흥률사), Jongwon-Sa(정원사), Yon-Sa(연사), Gamro-Sa(감로사), Yongguam(영귀암) besides the publications of temples, there are publications of local branches of gangyengdogam(간경도감) such as Jinju(진주), Sangju(진주), Sangju(상주), Andong(안동), of local public agencies such as Gaelimbu(계림부), Dalsunggwan(달성관), and of private families of which 8 titles in the Koryo Dynasty and 13 titles of the Choson Dynasty. Among the "SSanggyae-Sa(쌍계사) publication" held in the Haeinsa, 9 titles including Chimungyonghun(치문경훈) are recklesaly preserved with dividing both in Gap temple(갑사) and in Haeinsa as the same publication. It is possible that other scattered present publications or remaining publications might have been remaining publication from those partly burnt ones of the complete publications. By means of the investigation on the catalogs of publications, 5 titles such as <> <> <> <> <> which are now kept in the Haeinsa moved from the Taegubu(대구부) or Yongyon-Sa(용연사) were newly identified.

The dissemination of scientific information in Society involves interactions among a number of publics and many kinds of information channels. There is a need for examining the the entire process of information dissemination for the solving many problems which scientific many problems which scientific communication is now confronted with, This paper is an attempt to identify the functions of a scientific journal as one of major inf. transfer media, to clarify the problems in performing the functions, and to synthesize various on-going efforts toward the improvement and solution of such problems. Some conclusions derived from this study are as follows; (1) a scientific journal was, is and will be the valuable primary source for the recording and controlling scientific in formation which plays a role as a main energy source in the scientific activities. (2) Traditional built-in delays involved in the communication by a scientific journal should be improved by way of some new methods and techniques such as, of establishing a publishing center, controlling vocabularies in the scientific papers, distributing pre-publication materials, etc. (3) There should be a organized special committe for scientific communication for the assuming the responsibilities of educating, planning and carrying out activities relating to scientific information. (4) To improve the function of a scientific journal as information transfer media, other informal primary media such as report, preprint, etc, and secondary media such as abstracts and indexes should be studied which will result in the clarification of unigue functions, and advantages and disadvantages of each media. as an information dissemination media. (5) Each government should pay attention to the national information system as a changing social system and should recognize the gap in speed between technological development and the change of a social system Technological development should be made a contribution to the improvement of social system.

The purpose of this study is to develop conceptualization models of reading, information, ICT, and digital literacy through conceptual differences of these literacy by reviewing and defining the concepts of literacy as well as reading, information, ICT, and digital literacy. Computer literacy has emerged as a concept that explains the phenomenon of contemporary social, cultural, and information technology development, and since then, computer literacy has since changed to IT, ICT literacy, and digital literacy. As a result of the study, a conceptualization model of the reading, information, ICT, and digital literacy was developed. In this model, these literacy whose terms have changed according to the technological development of media, have been classified as medium-centered literacy. And reading and information literacy that focuses on the cognitive process of understanding, utilizing, and evaluating texts and information is categorized as process-oriented literacy. In the digital environment, reading and information literacy is a core competence to critically think and evaluate the texts that are on media, and further research is needed to reduce the reading and the information gap among readers.

This exploratory study outlines the rationalization of why Ontology's taxonomy requires a strong hierarchy, accuracy, and interoperability in order to be used as a successfully re-useable information management system. Finding the relevant information in a plethora of possible resources by bridging the gap between the user's needs and the resources of the information technology system is the goal that the information management field should find a way to achieve. This study is based on discussions and interviews with a taxonomist, information architect, and information manager, whose discussions were based on the usability and interoperability of the knowledge based information systems. These professional perspectives are necessary as they are the liaison between users and the information technology group. We found that in order for information managers to ensure successful sharing of knowledge across the end users, a common sense language must be issued in order to achieve reasoning for the artificial intelligence system.

The computing power of graphics processing units(GPU) has already surpassed that of CPU and the gap between their powers is getting wider. Thus, research on GPGPU which applies GPU to general purpose becomes popular and shows great success especially in the field of parallel data processing. Since the implementation of cryptographic algorithm using GPU was started by Cook et at. in 2005, improved results using graphic libraries such as OpenGL and DirectX have been published. In this paper, we present skills and results of implementing block ciphers using CUDA library announced by NVIDIA in 2007. Also, we discuss a general method converting source codes of block ciphers on CPU to those on GPU. On NVIDIA 8800GTX GPU, the resulting speeds of block cipher AES, ARIA, and DES are 4.5Gbps, 7.0Gbps, and 2.8Gbps, respectively which are faster than the those on CPU.
