  • 본 논문에서는 훈련용 워게임모델의 근접전투 피해평가를 위한 새로운 근접전투전문가시스템을 제안하였다. 군에서 사용하고 있는 워게임모델에서 피해평가 모의논리는 아주 중요한 모의가능이다. 현재, 육군의 군사단급 워게임모델인 창조21 모델에서는 근접전투 피해평가의 핵심기능이 창조21 모델에서 계산되지 않고, 공개소스와 내부논리를 알 수 없는 미군에서 제작한 근접전투전문가시스템(일명 COBRA)에서 별도로 계산되고, 이 결과가 네트워크를 통해 창조21 모델로 전송되어 근접전투에 대한 피해평가가 이루어진다. 본 논문에서는 COBRA를 대체할 수 있는 근접전투전문가시스템을 의사결정나무를 이용해서 제안하였다. 제안하는 시스템은 실험결과 COBRA와 유사한 성능을 보였고, 시스템의 계산량이 적었고 군사작전 상황에 적합하였다.

  • Background: To systematically review the literature for methods to localize the genial tubercle as a means for performing an advancement of the genioglossus muscle. Methods: PubMed, Google Scholar, CRISP, EMBASE, CINAHL, and Scopus were searched from inception through June 16, 2015. Results: One hundred fifty-two articles were screened, and the full text versions of 12 articles were reviewed in their entirety and 7 publications reporting their methodology for localizing the genial tubercle. Based upon these measurements and the results published from radiographic imaging and cadaveric dissections of all the papers included in this study, we identified the genial tubercle as being positioned within the mandible at a point 10 mm from the incisor apex and 10 mm from the lower mandibular border. Conclusion: Based upon the results of this review, the genial tubercles were positioned within the mandible at a point 10 mm from the incisor apex and 10 mm from the lower mandible border. It may serve as an additional reference for localizing the genial tubercle and the attachment of the genioglossus muscle to the mandible, although the preoperative radiological evaluation and the palpation of the GT are recommended to accurately isolate.

  • When the wind turbine is used in cold regions, the mechanical properties and dimension stability of the blade will be changed. The proposal of this paper is to test the durability of the blade for wind turbine. It is necessary to select the most comfortable materials and fabrication processes for more stable wind turbine blade in cold regions. To select the most comfortable materials and processes, the static strength has to know through the tensile static tests at the severe condition as cold regions. First, the tensile static specimens made by RIM (Resin injection molding) process & vacuum bagging process with reinforcement materials and resin. Tensile static tests were carried out on three laminate lay-ups (carbon prepreg, carbon fiber dry fabric and glass fiber dry fabric) at different test temperature($24^{\circ}$, $-30^{\circ}$), determining properties such as the mechanical strength, stiffness and strain to failure. At different test temperature, in order to test the tensile strengths of these specimens used the low temperature chamber. Next, the results of this test were compared with each other. Finally, the most comfortable materials and fabrication processes can select based on these results. The results show the changes in the static behavior of three laminate lay-ups at different test temperatures. At low temperatures, the static strengths are higher than the ones at room temperature.

  • Purpose: This study purposed to investigate the relationship between soldiers' general characteristic and their knowledge, attitude and health-belief about AIDS. Method: This study conducted a survey of 197 soldiers using a structured questionnaire. Data were collected from the 10th to 30th of May 2003. Result: The average age of the participants was 21.6 years, 78.2% of them were undergraduates of universities, and by religion the number of Christians was largest. In addition, 81.2% of them had lived with their parents and siblings before they joined the army and most of them were unmarried. Of the subjects, 75.1% finished education about AIDS, 64.5% experienced a sexual intercourse and 6.3% experienced a venereal disease. The participants' knowledge level about AIDS was 14.6 out of 20 points and their attitude about AIDS is 3.96 out of 5 points on the average. Their health-belief about AIDS was 4.0 out of 5 points in 'perceived benefits,' 2.9 in 'perceived barriers,' 2.6 in 'perceived seriousness' and 2.6 in 'perceived sensitivity. Among the subjects' general characteristics, religion was found to be a statistically significant variable for their knowledge level about AIDS. A variable that is statistically significant for the subjects' attitude toward AIDS was families they had lived together before joining the army. Statistically significant variables for the subjects' health-belief about AIDS were perceived sensitivity and experience in venereal diseases, perceived benefits and AIDS education and perceived barriers and marital status. The subjects' knowledge about AIDS was in a statistically significant correlation with their attitude toward AIDS, and their attitude toward AIDS with perceived benefits. Conclusion: According to the results of this study. those who had had AIDS education appeared to have high attitude and health-belief concerning AIDS. Thus it is necessary to execute AIDS education systematically and continuously in order to have right attitude and high health-belief concerning AIDS.

  • Since the end of the cold war, technical tie-up between private corporations and an army in developed countries has increased a lot, and the trend is spreading through developing countries rapidly. To cope with the circumstance actively, the dual use technology program for both private corporations and an army was begun in Korea in 1998. With the program, overlapping investment was resolved and technology transfer was stimulated. And the standardization and information exchange saved considerable national budget and made possible economic profit. Yet, the combination project of 4 ministries and offices showed problems such as loose cooperation and, low industralization record. However, developed countries are out of the mere stage of dual technology development and turn into broad technical tie-up including future prediction, national competitiveness improvement, and the private company's leading participation and they are systemizing them very fast. Korea also set up the national defense reform plan with the blueprint of future military force improvement, budget increase for national defense research, and increased participation of private corporations, and created Defense Acquisition program Administration to support them. The innovation of national defense system brings forward the need to link the private and military innovation. Korea has pursued the fast growth through assimilation, absorption, and improvement of foreign technology. But now, Korea has to focus on self innovation, original technology, parts and material. As this applies to private companies and military equally, it is important to concentrate limited resources for the effective technology cooperation. Considering this, the strategies to activate the dual use technology are program concept and range extension, task-deduction way improvement and future-oriented common task deduction, and promotion system improvement.

  • Currently, environmental contaminants that can cause Aromatic types of hydrocarbons, less than 1% made of Aromatic Free kind of used products, soybean oil products with linseed oil with the products, rice products using a wide range of environmentally ecological ink since 2000 is released quickly. All materials used in printed material, if the green is the best way to print the composite materials in industrial applications, because each process on the print quality and productivity, there can be many differences in this experiment because it accounts for a large proportion in the print general ink in the ink section and the International color standards(ISO2846-1:2006) certified ecological ink were compared. Therefore, in this paper has the ink released from the same company, each common general ink and ecological ink in the same condition which results were focused on whether the emerging international color standard(ISO 2846-1:2006) recognized for environmentally ecological ink printed color reproduction of the actual offset(color reproduction) how conformity to ISO 12647-2 standard color on the basis of the offset would check Color Reproduction. Based on the results of the experiments of this study, given the ecological ink coated paper, uncoated paper both color difference and the gamut of the ISO 12647-2 standard is suitable for ecological ink, the ink's color gamut reproduction, even more than existing international standards, there is no confirmed that the correct color reproduction possible. Using environmentally ecological ink industries is expected to respond to environmental policy.

  • 최근 많은 국가들이 NCW (Network Centric Warfare)를 구현하는데 기반이 되는 전술 애드 혹 네트워크의 성능을 향상시키기 위한 통신 프로토콜 개발을 활발히 진행하고 있다. 전투 무선망 (CNR, Combat Net Radio)은 육군의 보병과 같은 지상군에 있어 가장 중요한 통신 기반망이다. 미군은 전투 무선망에서 음성 및 데이터 통신을 위해 MIL-STD-188-220D을 개발하여 운용 중에 있다. 한국군의 차기 무전기인 전술 다대역, 다기능 무전기(TMMR)의 MAC 프로토콜의 후보인 MIL-STD-188-220D은 여러 제한사항이 존재한다. MIL-STD-188-220D에 정의된 DAP-NAD는 충돌회피를 위해 시간 동기를 필요로 하지만, 1홉을 벗어난 다중 홉의 환경에서는 시간 동기를 맞추기 어렵다. 다중 홉 환경에서 충돌을 방지하여 지연을 방지하는 향상된 DAP-NAD를 제안하였으며, 모의실험을 통하여 다중 홉 전투 무선망 환경에서 제안기법의 성능이 향상되는 것을 보였다.
