  • The near infrared ray camouflage fabric has a near infrared ray reluctance similar to the surrounding environment and has a camouflage effect on the surrounding environment. Synthetic fibers used in military uniforms are difficult to have gastrointestinal function as general commercial dyes, unlike cellulose fibers, which use some commercial vat dyes to impart infrared gastrointestinal function. In this study, we optimized the adsorption pH, temperature and time for NIR dye application for polyester fabrics, and established the optimum concentration for the evaluation of adsorption build-up characteristics. In addition, it is difficult to adsorb it since the polyester material has a dense crystal structure and the NIR dye is bulky. Therefore, a swelling agent used for dyeing meta-aramid fibers with high Tg and high crystallinity was introduced as a separate preparation to increase the affinity to polyester, which is a hydrophobic fiber, to thereby obtain an excellent adsorption rate. As a result of comparing before and after using swelling agent, the adsorption rate difference was 10 times or more when compared with before.

  • ln this study, we analyzed 5 science textbooks currently used for the 7th graders quantitatively by using the science textbook rating system of Collette and Chiappetta(1986), making meta-analysis of the results of 17 graduate school students of Seoul National University. The rating system consists of 11 categories with detailed items respectively : content, organization, reading level, instruction approach, illustrations, end-chapter teaching aids, laboratory activities in text and/or accompanying manual, teacher aids, indices and glossaries and mechanical makeup of text. Each item in the checklist is to be given between one and five points and the total number of possible points in this rating system is 290. It was shown that 5 science textbooks currently used for 7th-year-students were all "poor" in terms of total points and had, at large, uniformed results especially in 10 items; 7 items concerning moral and ethical implications of science, vocabulary lists, accompanying laboratory manual, annotated editions for test, supply list for laboratory program, student workbook and glossary with low points, while 3 items concerning facilities needed for laboratory activities, activities relevant to the content and textbook size with high points. A Science teachers could get a broad view with a correct impression of the books usefulness in making an evaluation of available textbooks.

  • The scope of the problems that could be solved by monitoring and the improvement of the recognition time is directly correlated to the performance of the management function of the business process. However, the current monitoring process of business activities decides whether to apply warnings or not by assuming a fixed environment and showing expressions based on the design rules. Also, warnings are applied by carrying out the measuring process when the event attribute values are inserted at every point. Therefore, there is a limit for distinguishing the range of occurrence and the level of severity in regard to the new external problems occurring in a complicated environment. Such problems cannot be ed. Also, since it is difficult to expand the range of problems which can be possibly evaluated, it is impossible to evaluate any unexpected situation which could occur in the execution period. In this paper, a process-evaluating model based on the goal scenario is suggested to provide constant services through the current monitoring process in regard to the service demands of the new scenario which occurs outside. The new demands based on the outside situation are analyzed according to the goal scenario for the process activities. Also, by using the meta-heuristic algorithm, a similar process model is found and identified by combining similarity and interrelationship. The process can be stopped in advance or adjusted to the wanted direction.

  • 본 연구는 사이버윤리와 관련된 2002년부터 2012년까지의 국내 연구들을 메타 분석하였다. 가장 연구가 활발한 연구 분야는 교육학분야로 나타났고, 그 외의 분야로는 법학, 신문방송학, 철학, 사회복지학, 사회학, 행정학, 경영학, 심리학 순이었다. 사이버 윤리는 각 전공분야별로 중점적인 연구 영역이 다르게 나타났다. 사이버연구 분석결과 사이버 공간의 특수성을 반영한 윤리이론 개발이 미흡하고, 대부분의 연구들이 기존의 윤리 철학적 범주를 벗어나지 못하는 경향을 보이는 것이 문제점으로 지적된다. 사이버윤리에 대한 연구의 경향이 추상적인 도덕규범 정립에 그치는 것도 문제점으로 볼 수 있다. 또한 새롭게 등장하는 정보인권에 대한 인식 또한 부족하여 실천적 생활윤리에 관한 연구가 미흡하였다. 향후 연구에 있어서 사이버 공간의 정보인권적 윤리의식이 제고되어야 하고, 학제간의 융합적인 연구의 필요성도 요청된다.

  • This study presents a strategy so-called Subspace Search Mechanism (SSM) for reducing the computational time for convergence of population based metaheusristic algorithms. The selected metaheuristic for this study is the Cuckoo Search algorithm (CS) dealing with size optimization of trusses. The complexity of structural optimization problems can be partially due to the presence of high-dimensional design variables. SSM approach aims to reduce dimension of the problem. Design variables are categorized to predefined groups (subspaces). SSM focuses on the multiple use of the metaheuristic at hand for each subspace. Optimizer updates the design variables for each subspace independently. Updating rules require candidate designs evaluation. Each candidate design is the assemblage of responsible set of design variables that define the subspace of interest. SSM is incorporated to the Cuckoo Search algorithm for size optimizing of three small, moderate and large space trusses. Optimization results indicate that SSM enables the CS to work with less number of population (42%), as a result reducing the time of convergence, in exchange for some accuracy (1.5%). It is shown that the loss of accuracy can be lessened with increasing the order of complexity. This suggests its applicability to other algorithms and other complex finite element-based engineering design problems.

  • This study was conducted to examine the current status of traditional korean medicine studies on gastroesophageal reflux disease in Korea, identify deficiencies, and suggest the direction of future medicine research methods to lay the foundation for traditional korean medicine treatment. All domestic papers on the korean traditional treatment of gastroesophageal reflux disease were selected among the literature published until August 2022 in six domestic databases. A total of 52 selected research data were classified into experimental research papers, clinical research papers, and review papers. In experimental papers, to evaluate the effectiveness of treatment, improvement of esophageal mucosal lesions, anti-inflammatory mechanisms, antioxidant mechanisms, esophageal mucosal protection mechanisms, gastric peristalsis control, and gastric acid secretion inhibition mechanisms were used as evaluation measures. In the clinical research paper, the basis for diagnosis of cases was clinical symptoms through medical history listening and diagnosis through visits to hospitals in the past. The average treatment period was 40.7 days, and the duration of treatment was not significantly affected by the duration of the disease. The most widely used Korean medicine treatment intervention was herbal medicine. There were 3 literature review studies, 3 systematic literature review and meta-analysis studies, 1 comparative review study for clinical trial guideline development, all using Chinese papers. This study included all domestic papers on gastroesophageal reflux disease to identify the research trend of the Korean oriental medicine community, and based on this, it is meaningful to confirm areas that need to be supplemented in future research plans.
