  • The purpose of this study lies in identifying Korean scientists' dependency on foreign scientific and technical information (STI), with emphasis on investigating the causes and results. Especially, this study intends to investigate the impacts that a growing dependency on foreign STI might have brought and will bring about on the development of indigenous STI in ROK. To the end, the present discussion covers the following specific research questions: 1) what are the major information sources used by Korean scientists to locate STI necessary for research-related activities\ulcorner 2) to what extent do Korean scientists use foreign STI for research-related activates, as compared to the use of domestic STI\ulcorner 3) what are the major factors causing the information dependency among Korean scientists and what are the results of the growing information dependency\ulcorner And finally, 4) what suggestions can be made for ROK to further its indigenous STI development, while minimizing its dependency on foreign STI\ulcorner Survey method, together with citation analysis method, is employed as the major data collection technique. The survey sample consists of 167 most 'representative' Korean scientists selected on the basis of their research productivity. 167 specially-designed questionnaires were mailed and 104 out of 167 were responded. Follow-up interviews were carried out for 32 out of 104 respondents, who returned the questionnaire but did not answer some specific questions. The data collected from these 104 respondents were analyzed on the basis of two distinguished groups namely, junior and senior scientist groups. Among the 104 respondents, 58 a n.0, ppeared to belong to a group of senior scientists (older than age 45 and finished their final degrees since 1980), and 46 belonged to a group of junior scientists (younger than age 45 and finished their final degrees before 1980). The major findings of the present study include: 1) Korean scientists regard 'scientific and technical journals and books'as the most important information source to obtain the recent STI; 2) their dependency on foreign STI, for the purposes of research and teaching, is extremely high (information dependency for research activities is 88.5%, and that for teaching activities 91.2%); 3) the information dependency of junior scientists are higher than that of senior scientists; 4) Korean scientists' growing information dependency is closely related to both small quantity and low quality of domestically-produced STI, and has a statistically significant relationship with their educational background; and finally, 5) in order to theoretically explain the growing information dependency of Korean scientists, a hypothesis - 'chronic cycle of information dependency' was developed and introduced. The present study suggests the promotion of indigenous STI as a desirable alternative to escape from the 'chronic cycle of information dependency. Localization of the imported foreign STI is suggested as a good strategy for the indigenous STI development, and also suggested are STI policies for both success of localization process and promotion of more efficient STI flows at national and international level.

  • Due to the recent advancement of networking and high-performance computing technologies, scientists can easily access large-scale data captured by scientific measurement devices through a network, and use huge computational power harnessed on the Internet for their analyses of scientific data. However, visualization technology, which plays a role of great importance for scientists to intuitively understand the analysis results of such scientific data, is not fully utilized so that it can seamlessly benefit from recent high-performance and networking technologies. One of such visualization technologies is SAGE (Scalable Adaptive Graphics Environment), which allows people to build an arbitrarily sized tiled display wall and is expected to be applied to scientific research. In this paper, we present a multi-application controller for SAGE, which we have developed, in the hope that it will help scientists efficiently perform scientific research requiring high-performance computing and visualization. The evaluation in this paper indicates that the efficiency of completing a comparison task among multiple data is increased by our system.

  • 전통적으로 과학데이터 시각화는 데이터 분석과 관련이 깊은 연구 수행과정 중의 하나로 간주되어 왔다. 그러나 최근 들어서 과학데이터 시각화의 연구영역 자체가 독립적인 학문분야로서 자리를 잡기 시작하면서 시각화의 기술 및 방법들이 점차 고도화되고 복잡해지고 있다. 그러나 과학데이터 시각화 연구가 개인 및 그룹의 연구자들 스스로의 노력으로 시각화 문제를 해결하는 데 있어서 한계가 있다. 따라서 전문집단에 의한 체계적인 지원의 필요성이 대두되고 있으며, 본 연구는 거시적 관점의 국가수준에서 어떻게 과학데이터 시각화를 체계적으로 지원할 것인가를 정책적인 시각에서 분석하였다. 구체적으로 기존 문헌의 조사를 통하여 주요 성공요인들을 파악하였으며, 집중적으로 투자해야 할 연구의 영역을 설정하였다. 다음으로 국가수준의 시각화 연구지원의 전략적인 방향과 전략적 과제를 제언하였다.

  • Clinical laboratory testing plays a crucial role in the detection, diagnosis, and treatment of disease. Clinical laboratory scientists evaluate test results, develop and modify procedures, and establish and monitor programs, to ensure the accuracy of tests. It is clear that over the past decade the role of the clinical laboratory scientists has expanded and this process will be continued into the future. The purpose of this study is to clarify the factors influencing the job performance of clinical laboratory scientists and aim to provide the role and duties of clinical laboratory scientists. To examine the frequency of work context and the importance of task, the surveys were conducted on 168 clinical laboratory scientists. The questionnaire items were used 10 score by Likert scale. According to the results of this study, the important factor affecting the job performance was "Analyze laboratory findings to check the accuracy of the results", and the next factors were "Establish and monitor quality assurance programs", "Enter data from analyzer into computer", "Calibrate and maintain equipment". And the factors of "repeating same tasks" and "spend time making repetitive motions" were answered the highest. This study will provide strategies for improving work environment, developing education curriculum and method, and role of clinical laboratory scientists. We must continually upgrade our knowledge, and identify the new trends in technology and science and accept changes.

  • The purpose of this study is to provide the basic guidelines of spatial and physical environment for the planning and design of clinical laboratory by analysing the extent of satisfaction of clinical laboratory scientists. The data for this analysis was gathered from March to May 2005 by the questionnaires of 208 clinical laboratory scientists who work in the 13 hospitals. All the collected data was analyzed by the SPSSWIN program. In this study, the satisfaction measurement tool was composed with 8 items and 5 score scale. The mean score of satisfaction for spatial and physical environment was 2.89 out of 5.0, "noise" was the lowest 2.40, "temperature and moisture of the lab." was 2.72, "lab. area, service area and administration area" was 2.77, "passageway space" was 2.94, circulation of workers was 2.94, "color of finish" was 3.19, "lighting of lab." was the highest 3.39. In conclusion, various factors, noise, temperature and moisture, clinical lab area, were evaluated to moderate dissatisfaction. Noise was especially the first serious problem in clinical lab. Considering the high growth of the number of tests, the planning of the clinical laboratory size should be considered not only to provide the optimal size but how it will correspond to the growth of the number of tests. Therefore the arrangement of each section need to be flexible in arrangement which is inevitable in expansion and reconstruction in the future.
