본 논문에서는 웨이블릿 변환과 Direct LDA(DLDA)을 사용한 홍채 특징추출 방법을 제안한다. 이것은 획득한 홍채 영상으로부터 독특한 특징을 추출하기 위해 특별히 이차원 이산 웨이블릿 변환의 다중해상도 분해 방법을 사용하는 것이다. 또한 홍채의 다양한 웨이블릿 성분으로부터 변별력을 가진 특징을 얻을 수 있도록 DLDA기법을 적용하였다. 이러한 특징추출 방법은 이동이나 회전에 변하지 않는 알고리즘을 요구하는 홍채의 모양을 묘사하는데 적합하다. 홍채 패턴정합을 위해서는 최근접 평균 분류기 (Nearest Mean Classifier)를 사용하였다. 본 논문에서 인간의 홍채인식을 위해 제시한 방법이 홍채패턴을 표현하는 효과적인 방법이며, 시간 및 공간의 절약이라는 측면에서 유리하다는 것을 보여준다.

Purpose: The aim of this study was to examine the effects of long-term endurance exercise and natural fermented vinegar on body composition and cardiopulmonary function of 50-aged postmenopausal women. Methods: Subjects were divided into four groups (sedentary group, aerobic exercise group, natural fermented vinegar group, and aerobic exercise plus natural fermented vinegar group) to perform natural fermented vinegar intake or aerobic exercise for 8 weeks. Body weight, body composition, cardio-pulmonary function test, and blood concentration of glucose, lipid profiles, aspartate aminotransferase, and alanine aminotransferase were measured. Results: The results showed that natural fermented vinegar or aerobic exercise training for 8 weeks no significantly improved body weight control and body composition. However, natural fermented vinegar plus aerobic exercise training for 8 weeks significantly improved cardiopulmonary function. Conclusion: These results suggest that natural fermented vinegar plus aerobic exercise training has a significant effect on anti-fatigue.

Although marathon has been considered as a simple or natural event, the multiple factors affect its performance such as physique and physical fitness including physical, technical, and mental factors. Academic disciplinary topics for talent identification in marathon performance are supported by physical characteristics, exercise physiology, biochemistry, nutrition, psychology, biomechanics, development and growth, evaluation and measurement. The scientific factors of marathon consist of physical and physiological characteristics of runners, overcoming trial of environmental effects, nutritional and psychological approach, ergogenic aid, effective training program, shoes and clothes. Especially, cardiopulmonary-related physical fitness is evaluated by maximal oxygen uptake, anaerobic threshold, oxygen transport rate, and lactate tolerance. These scientific approaches for the improvement of running performance have been applied to the pick-up of excellent runner, exercise training, and actual running race for the overcome of limiting factors as environmental condition, exercise-induced fatigue, and injury, etc. In conclusion, we must consider the scientific factors for actual running race with physiological or psychological paradigm, technical application, nutritional approach, genetic analysis and information and communication and technology (ICT) convergence science for the scientific consideration of improvement in marathon running performance.
