조환제,강도원,박태곤 창원대학교 산업기술연구소 2001 産技硏論文集 Vol.15 No.-

In this study, we used Brewster-Angle Microscope(BAM) to study on the molecular orientation of monolayer on the water surface. The domains by behaviors of molecules on three different subphase have been observed. Reproducible π-A isotherm have been obtained only on information about phase transition by molecular area. BAM facilitates the observation of morphology by optical anisotropy and thickness in monolayer and multilayers as BAM is shown to be sensitive to anisotropy of film. Also, the coalescence of domains leads to large regions of uniform tilt-azimuthal direction. Every transition was found by BAM technique, either as a dramatic change in degree of contrast or as a sudden alteration of molecular action and π-A isotherm.

신제품이 개발 출시되어 크게 성장 할 수 있다는 것은 그것을 채택, 수용해 줄 수 있는 혁신층과 조기수용자 층의 소비자 구조를 가지고 있어야만 한다. 신제품 수용자의 조기 확보는 신제품 개발에 소요된 비용은 조기에 보충할 수 있고, 많은 고객을 확보하여 매출의 증대가 용이하고, 마케팅비용의 감소를 가져올 수 있으며. 시장에서 리더십을 가짐으로써 효과적 시장 진입이 되기도 한다. 이와 같이 신제품의 수용과 확산의 연구에서 혁신성이 차지하는 중요도가 매우 높기 때문에 많은 관심을 끌어 온 것이 사실이다. 그러나 이러한 혁신과 수용성 연구의 중요성에 비추어 혁신성에 대한 발견 사실의 모호성과 함께 관련변수에 관한 끊임없는 논의가 지속되어 왔고, 동시에 혁신성 연구가 지금까지 취하여 왔던 방향과 주제에 관련해서도 많은 비판이 이루어져 온 것도 사실이다. 이러한 관점에서 본 연구에서는 아직 논리적으로나 실체적으로 방법론이 확립되어 있지 않은 디자인 혁신의 개념을 새롭게 정립하고 그 특징과 요소를 분석하고 객관적인 기준으로 변한 할 수 있는 지표를 찾는다. 또한 디자인 혁신에 있어서 유사성 판단에 관한 실험을 통해 제품 집단의 유형과 기준을 명확히 파악하고 각 샘플의 공간 해석과 함께 시자극적 특성을 정량적으로 평가하는 실험적 이론으로 사용하고자 한다. 이는 디자인에 있어서의 혁신을 인지하고 각 제품 속에 속한 샘플들을 특징별로 지각하는 보다 과학적인 디자인 접근방법에 관해 새로운 방향을 모색할 수 있도록 하였다. If a new product Is devised and to be sold, it Should possess the group of people who are inclined to change and accept the product, and the group of consumers who can buy them. If you occupy the consumers to buy the products earlier, you car make up with the expenditure that you have spent to devise and make products, facilitate the raise of the sales, decrease the marketing expenditure, and have effective access to the market by going ahead of others. Like this the Innovation has great influence in the accepting and spreading of the products. However in spite of these Innovation and acceptance, there have kept the ceaseless disputes about finding the Innovation and related function, at the same time the study of innovation has been criticized about the direction and the theme we have taken until now. From this point of view, the methodology has not been established In the area of logic and its reality, and this study tries to set up the concepts and analyze the characteristic and the elements and find the standard to change those characteristics and elements in to objective standard. In addition, through the judgment of the similarity In the design innovation, it tries to identify clearly the types and the standard of the set of the products, Interpret the space of each sample, and use it as the experimental theory to evaluate the visual characteristics, Thus it can perceive innovation of the design. perceive the characteristics of the samples in each products, and find the new direction in the more scientific access to design.

The study compared to skills of Yeopchagi and Dolyeochagi in Taekwondo with the 3d kinematic analysis. To compare both of two skills, the study was analyzed as the relative time during the skills performed, the kinematic characteristics of individual segment, the relationship of inter-segment and the ranges of motion in 3d space. A performance time was mort shortened Dolyeochagi than Yeopchagi. A relative time that the time minimized angle of shank was later Dolyeochagi than Yeopchagi. The characteristic of kinematic of Individual segments showed clearly different in the flexion/extension plane. The angle of thigh increased continuously at an impact in Yeopchagi, but the angle stopped or decreased in Dolyeochagi at that time. The relationship of inter-segment showed difference largely between two skills in the flexion/extension plane, but the other plane showed no difference. These results were due to anatomical functional difference between two joints. The ranges of motion in 3d space were different at the abduction/adduction and the internal/external rotation.

Objectives : The purpose of the study was to assess the risk factors assumed to be related to the high frequency hearing loss in the noise-exposed male workers. Methods : 712 occupationally noise-exposed male workers were included in this cross sectional study. The subjects filled out a questionnaire on the history of noise exposure, hearing protection, otologic diseases, tobacco smoking, and were tested on height, weight, hematocrit, serum total cholesterol level, fasting plasma glucose level and arterial blood pressure level. Pure tone audiometry and otoscopy were conducted and the subjects were allocated into two groups according to whether they had 4000 Hz hearing loss or not. Results : The multiple logistic regression analysis showed that military noise exposure, poor wearing status of the hearing protection devices, increased age, long noise exposure duration, mean arterial pressure less than 80mmHg, high fasting plasma sugar are the factors significantly related to high frequency hearing loss (P〈0.05). On the contrary, there was no significant relationship between noise intensity, body mass index, serum total cholesterol level, smelling and high frequency hearing loss. Low hematocrit was shown to be a significant factor with a p-value less than 0.1. Conclusions : High frequency hearing loss in the noise-exposed male workers is related to military noise exposure, use of hearing protection devices, age, noise exposure length, fasting glucose level and mean arterial pressure, in this order. Appropriate use of the hearing protection devices has a great impact on the prevention of the noise-induced hearing loss.

Y. W. JIN, J. M. SHIN. Biomechanical Comparative Analysis of Two Goal-Kick Motion in Soccer. Korean Journal of Sport Biomechanics, Vol. 15, No. 1, pp. 29-44, 2005. The purpose of this study is to reveal the effects of two different kicks, the drop kick and the punt kick, into the kicking motion, through the kinetic comparative analysis of the kicking motion, which is conducted when one kicks a soccer goal. To grasp kinetic changing factors, which is performed by individual's each body segment, I connected kicking motions, which were analyzed by a two dimension co-ordination, into the personal computer to concrete the digits of it and smoothed by 10Hz. Using the smoothed data, I found a needed kinematical data by inputting an analytical program into the computer. The result of comparative analysis of two kicking motions can be summarized as below. 1. There was not a big difference between the time of the loading phase and the time of the swing phase, which can affect the exact impact and the angle of balls aviation direction. 2. The two kicks were not affected the timing and the velocity of the kicking leg's segment. 3. In the goal kick motion, the maximum velocity timing of the kicking leg's lower segment showed the following orders: the thigh(-0.06sec), the lower leg(-0.05sec), the foot(-0.018sec) in the drop kick, and the thigh(-0.06sec), the lower leg(-0.05sec), the foot(-0.015sec) in the punt kick. It showed that whipping motion increases the velocity of the foot at the time of impact. 4. At the time of impact, there was not a significant difference in the supporting leg's knee and ankle. When one does the punt kick, the subject spreads out his hip joint more at the time of impact. 5. When the impact performed, kicking leg's every segment was similar. Because the height of the ball is higher in the punt kick than in the drop kick, the subject has to stretch the knees more when he kicks a ball, so there is a significant affect on the angle and the distance of the ball's flying. 6. When one performs the drop kick, the stride is 0.02m shorter than the punt kick, and the ratio of height of the drop kick is 0.05 smaller than the punt kick. This difference greatly affects the center of the ball, the supporting leg's location, and the location of the center of gravity with the center of the ball at the time of impact. 7. Right before the moment of the impact, the center of gravity was located from the center of the ball, the height of the drop kick was 0.67m ratio of height was 0.37, and the height of the punt kick was 0.65m ratio of height was 0.36. The drop kick was located more to the back 0.21m ratio of height was 0.12, the punt kick was located more to the back 0.28m ratio of height was 0.16. 8. There was not a significant difference in the absolute angle of incidence and the maximum distance, but the absolute velocity of incidence showed a significant difference. This difference is caused from that whether players have the time to perform of not; the drop kick is used when the players have time to perform, and punt kick is used when the players launch a shifting attack. 9. The surface reaction force of the supporting leg had some relation with the approaching angle. Vertical reaction force (Fz) showed some differences in the two movements(p<0.05). The maximum force of the right and left surface reaction force (Fx) didn't have much differences (p<0.05), but it showed the tendency that the maximum force occurs before the peak force of the front and back surface (Fy) occurs.
