디지털 보존 주제분야를 중심으로 지식영역 비주얼화(knowledge domain visualization)를 시도하였다. 분석을 위한 데이터는 1990년부터 2005년까지의 기간 동안의 Web of Science DB를 중심으로 총 74건의 문헌을 추출하여 활용하였다. 지식영역 비주얼화를 위하여 사용한 툴은 서지DB를 중심으로 비주얼 데이터마이닝 결과를 제공하는 Java 어플리케이션인 CiteSpace이다. 분석 결과, 디지털 보존 분야의 핵심적인 지식 영역은 최신정보기술을 중심으로 한 디지털 보존전략, 정보네트워크와 보존시스템, 전자정부와 지식관리의 세 영역인 것으로 나타났다.

To analyze the effect of reminder type on the development of time-based prospective memory of children, 270(90 each 5-, 7-, and 9-year old) participants were randomly divided by age group into three subgroups : self-cued reminder, other-cued reminder, and control groups. Results showed that the performance of time-based prospective memory significantly increased with age, and the presentation of reminders was effective for improving the performance of time-based prospective memory. For younger children the presentation of other-cued reminder was more effective than self-cued reminder, but for the older children, presentation of self-cued reminder was more effective than other-cued reminder.

Sb-doped tin oxide films were deposited on Corning glass 1737 substrate by plasma enhanced chemical vapor deposition(PECVD) technique using a gas mixture of SnCl4/SbCl5/O2/Ar. The deposition behaviors of tin oxide films by PECVD were compared with those by thermal CVD, and effects of deposition temperature, r.f. power and Sb doping on the electrical properties of tin oxide films were investigated. PECVD technique largely increased the deposition rate and smoothed the surface of tin oxide films compared with thermal CVD. Electrical resistivity decreased with doping of Sb due to the increase of carrier concentration. However, large doping of Sb diminished carrier concentration and mobility due to the decrease of crystallinity, which resulted in the increase of electrical resistivity. As the deposition temperature and r.f. power increased, Cl content in the film decreased.

Precision electronic equipments for outdoor use are composed of sophisticated microcircuits that are extremely vulnerable to lightning-caused voltage spike. This transient voltage spike may cause upset, latent failure or Interference on electronic equipments. In order to develop efficient lightning protection measures on AC power lines of a road traffic controller as a electronic equipment for outdoor use, experimental surge immunity tests were conducted according to IEC standard 801-5. The combination of gas tube arrester and metal-oxide varistor was installed at the input of AC power lines and the silicon avalanche suppressor installed at the output of DC power supply for the lightning protection measures.

Purpose: The purpose of this study was to determine core nursing intervention in nursing records and to compare perceived nursing intervention priority and nursing intervention frequency of general surgery department. Methods: Subjects were 70 nurses who work in the general surgery department. Data was collected using a nursing intervention classification and analyzed by frequency and mean. Results: The most frequent nursing interventions of nursing records were orderly risk management, coping assistance, tissue perfusion management, skin/wound management and nutrition support. Important nursing interventions were tissue perfusion management, respiratory management, electrolyte acid-base management, elimination, peri-operative care. The most frequent nursing interventions were drug management, peri-operative care, risk management, tissue perfusion management, patient education. Conclusion: This study found that nursing records were different from intervention priority and nursing frequency. So further study is needed for finding focused intervention of specific subjects and differences with priority of nursing and frequency of nursing.

This study is a bibliographical analysis on the Nam-Chungjanggong-sigo(남충장공시고), a wooden block printed book. On the view of physical bibliography, a table of contents on the Nam-Chungjanggong-sigo is compiled by a preface, a Chungjanggong's poetical works, an extra appendixes and an epilogue; and its wooden printing block has made of 52 plates. On the row of textual bibliography, text of Chungjanggong's poetical works is revised second times, such as each title or text, also title and text; and shorten for verses. And some of verses are prepared for revised the same case of compilation, but omitted in the process of last compilation.

In this study, we designed color of tunable and high efficient organic materials using the quantum dynamics and the semi-empirical calculation, and applied this results to the fabrication of organic light-emitting diodes. Also we optimized the molecular structure of phosphorescent materials and the energy transfer from a host to a dye which makes organic light-emitting diodes improve. Using quantum dynamics method, the molecular structures of ligand only and the whole metal chelate were optimized, and these energy levels were calculated. From this test results, we could understand the emission mechanism of phosphors with various ligands as well as design the proper ligands reducing the T-T annihilation and the carrier lifetime. We also could design ligands with various colors using this test method.

현재 국내 대학도서관에서는 웹을 통한 도서관 이용자교육이 미비한 실정이다. 따라서 본 연구는 기존문헌에서 나타난 웹 사이트 평가기준과 웹 기반 도서관 이용자 교육 프로그램의 평가기준을 종합한 평가 요소들을 도출하여 국내ㆍ외 대학도서관의 웹 기반 도서관 이용자 교육 프로그램을 비교ㆍ분석하였다. 이러한 분석결과를 바탕으로 웹 기반 도서관 이용자교육 프로그램의 설계에 대한 기준을 제시하여 향후 웹기반 도서관 이용자 교육 프로그램의 설계에 있어 토대를 마련하고자 하였다.

본 연구는 도서관에서의 비도서자료의 활용과 비도서자료에 대한 사서들의 인식 및 의견을 조사하였다. 설문지를 사용하여 129개의 데이터를 한국사회과학정보자료기관협의회의 31개 회원도서관과 98명의 사서로부터 수집하여 분석하였다. 분석결과, 도서관에서의 비도서자료의 활용은 매우 중요하다는 것이 밝혀졌다. 따라서 비도서자료의 활용은 좀더 활성화하기 위한 서지통정을 제안하였다.
