  • Semiconductor logistics systems are facing difficulties in increasing production as production processes become more complicated due to the upgrading of fine processes. Therefore, the purpose of the research is to design predictive models that can predict traffic during the pre-planning stage, identify the risk zones that occur during the production process, and prevent them in advance. As a solution, we build FABs using automode simulation to collect data. Then, the traffic prediction model of the areas of interest is constructed using deep learning techniques (keras - multistory conceptron structure). The design of the predictive model gave an estimate of the traffic in the area of interest with an accuracy of about 87%. The expected effect can be used as an indicator for making decisions by proactively identifying congestion risk areas during the Fab Design or Factory Expansion Planning stage, as the maximum traffic per section is predicted.

  • With advancements in satellite technology, interest in target detection and identification is increasing quantitatively and qualitatively. Synthetic Aperture Radar(SAR) images, which can be acquired regardless of weather conditions, have been applied to various areas combined with machine learning based detection algorithms. However, conventional studies primarily focused on the detection of stationary targets. In this study, we proposed a method to identify moving targets using an algorithm that integrates sub-aperture SAR images and cosine similarity calculations. Utilizing a transformer-based deep learning target detection model, we extracted the bounding box of each target, designated the area as a region of interest (ROI), estimated the similarity between sub-aperture SAR images, and determined movement based on a predefined similarity threshold. Through the proposed algorithm, the quantitative evaluation of target identification capability enhanced its accuracy compared to when training with the targets with two different classes. It signified the effectiveness of our approach in maintaining accuracy while reliably discerning whether a target is in motion.

  • This study was to investigate factors of risk perception on major environmental issues among general public and environmental experts in Korea. Structured questionnaire surveys were conducted to samples from general public and environmental experts during March and April, 2000. Total numbers of respondents were 773, general public and 353 experts. Analysis of the data showed that risk perception was correlated with health concern, environmental satisfaction, perception of environmental pollution, interest on the environmental issues, knowledge, experiences, and social-cultural consciousness, and so on. Overall environmental risk perception was affected by knowledge on environmental issues, experience of damage from environmental problems, sex and perception of environmental pollution. According to the results, environmental risk perception is not independent from social and psychological factors, and it may be desirable to consider the related factors in the process of risk communication for a more effective risk management or environmental policy.

  • To survey the present status of the gerontological nursing course at three year diploma programs, baccalaureate degree programs(BSN), and graduate programs in Korea, and to analyze the contents of the syllabus and gerontological nursing textbooks to provide the basic data in developing a standard model for gerontological nursing curriculum. Method: Data was collected from all the nursing programs in Korea from Nov. 2000 to Feb. 2001 by mail and fax. Result: The gerontological nursing courses has been offered 36 diploma program, 40 BSN, and 17 graduate programs. And the credits of the gerontological nursing course offered by the program were as follows : one credit (10 diploma and 8 BSN), two credits (22 diploma and 29 BSN), and three credits (1 BSN). The contents of curri- culum were analyzed by comparing the core curriculum of NGNA. The majority of the schools included Gerontological Nursing in General, Theory of Aging, Aging Processes, Care Plan Options, and Common Health Problems. The subjects which very few school cover are Legal/ Ethical Issues, Evaluation, Regulatory & Reimbursement Issues, Education Issues, Nursing Research in Gerontology, and Environmental Issues of Older Adults. There were some differences in these results among diploma courses, BSNs, and graduate schools. The gerontological nursing textbooks contained similar contents to those of the diploma and the baccalaureate programs.

  • The purpose of environmental education is to cultivate democracy citizens suitable for sustainable society. Suitable citizens for sustainable society are fostered person of environmental literacy, environmental sensibility, ecological and synthetic sights of environmental problems, decision making of environmental problems, and environmental responsibility etc. by environmental education. To achieve this purpose of environmental education effectively, it is desirable that produces and utilizes ICT(Information and Communication Technologies) works and methods that can show efficiently special sides(inter-relation, long-term effects etc.) of environmental problems. ICT environmental education materials and methods are raising the interest and participate of teenagers to environmental education because they are accustomed to the Internet in South Korea. Students can easily conversation with the person of similar interests and environment experts through cyber ICT environmental education. The directions of developing ICT teaching materials for environmental education to enforce self-directed learning, cooperation studying etc.

  • Background: As the public interest in chemical substances found in daily life has increased, environmental health education content has been developed and related studies have been conducted. However, there is still insufficient research on methodologies for environmental health education. Objectives: This study aimed to explore risk communication strategies by focusing on N-nitrosamines in rubber balloons. Methods: In this study, two different health messages were composed: a gain-framed message emphasizing the advantages of practicing the health behavior and a loss-framed message emphasizing the negative consequences of not practicing the health behavior. The effect of the message containing risk information was evaluated by measuring the health beliefs and health behavior potential for female caregivers. As the Environmental Health Act defines a child as "a person under the age of 13," a total of 131 women with children under the age of 13 were studied. Results: The age, awareness, and interest of the participants in the gain frame group and these in the loss frame group were similar. In terms of message framing effect, the gain-framed message was more effective in terms of health belief and potential health behavior than was the loss-framed message. As a result of an independent t-test, among the six variables of health belief model the message effect was statistically significant at the level of p<0.05 in three variables: perceived severity (t=2.287, df=129, p=0.024), self-efficacy (t=2.123, df=129, p=0.036), and health behavior potential (t=2.094, df=129, p=0.038). Conclusions: This study presented a direction for effective environmental health education by studying the effects of risk communication messages based on scientific evidence. It is necessary to extend the scope of environmental health education research by expanding research into various household products.

  • Genetic markers engendered by genome projects drew enormous interest in quantitative genetics, but knowledge on genetic architecture of complex traits is limited. Complexities in genetics will not allow us to easily clarify relationship between genotypes and phenotypes for quantitative traits. Quantitative genetics guides an important way in facing such challenges. It is our exciting task to find genes that affect complex traits. In this paper, landmark research and future prospects are discussed on genetic parameter estimation and quantitative trait locus (QTL) mapping as major subjects of interest.
