Proceedings of International Symposium on East-West Medicine, Seoul. 244-254, 1999.-Obesity can be defined as a metabolic disease due to an increased state of fat tissues caused by an imbalance of calorie intake and use. Recently, in Korea by improvement and westernization of food intake, along with decrease in exercise activities, the prevalence of obesity has increased greatly. Our objectives were to study stability and effects of decrease in body fat by administering red ginseng compound preparation (known to have body fat decreasing effects in laboratory animals) to obesity patients on low calorie diets. Changes in weight and body fat were measured while carrying out calorie-restricted diets on patients for 4 weeks, then administering red ginseng compound preparation for another 4 weeks. The patients were 20 people whose BMI were 25kg/㎡ or over and whose percent body fat was also 30% or over when tested by bioelectrical conductivity. 1. Changes in weight were from 70.04kg(base line) to 67.43kg(after taking red ginseng compound preparation). 2. In similar sense, BMI decreased from 27.12kg/㎡(base line) to 26.56kg/㎡(after dieting), and further to 26.01kg/㎡ (after taking red ginseng compound preparation). The BMI seemed to decrease significantly compared to the baseline after the use of red ginseng compound. 3. Waist hip ratio was changed from 0.8858(base line) to 0.8728, but it was statistically insignificant. 4. The percent body fat was 35,16%(base line), 33.87%(after dieting), and 31.68%(after taking red ginseng compound preparation). 5. Complete blood cell count and blood chemisrty remained unaffected by the administration. 6. In concern to endocrinologic studies, T3 decreased from 118.7 to 98.2ng/dL, and T4 increased from 8.8 to 9.2㎕/ dL. Epinephrine showed a tendency to decreased from 0.27 to 0.25 ng/mL, and norepinephrine increased from 0.39 to 0.44ng/mL. 7. Leptin was not changed. 8. Some patients complained adverse effects; constipation(5 patients, may be due to diet therapy), fatigue (2 patients), pruritus(2 patients), flushing(s patients), dizziness(3 patients) and epigastric discomfort(2 patients). However their symptoms were mild, so medication did not stopped. In conclusion, loss of weight without significant side effects was observed during low calorie diet and red ginseng compound preparation administration. This is thought to be in relation to sympathetic nerve system rather than adrenal gland. Also, further long0term studies should be required, since the observed results were based on short-term changes in weight.

This study was performed to investigate the effect of 12 weeks red ginseng intaking on the cardiovascular andcognitie performance in the middle-aged and elderly women. Sixty-four volunteers, all over 55 years of age, agreed to participate and were placed in 8 groups; in the elderly (65-74 yrs), ginseng intaking and exercise group(n=8), only exercise group(n=8), only ginseng intaking group(n=8), and control group(n=8); in the millde-aged(55-64 yrs), ginseng intaking and exercise group(n=8), only exercise group(n=8), only ginseng intaking group(n=8), and control group(n=8). The subjects who joined this program were asked to take red ginseng or participate in exercise program(3 times/week, 80min/day), depending on particular group for 12 weeks. They were tested on their heart rate for resting and sub-maximum exercise and cognitive performance tasks(information processing speed and WAIS-test) at the beginning and the end of the 12-weeks program. For data analysis, mean and standard deviatin scores were calulcated and ANOVAs were used. In the middle-aged, ginseng intaking was influenced on both information processing speed(represented by finger simple reaction time and choice reaction time), and spatial ability andinoformation processing performance on visual stimulation (Trail-making). There was also exercise effect on same tasks. But ginseng intakig was not influenced on cardiovascular function and other cognitive tasks(eye-hand corordination, digit-span, Digit-symbol substitution, tapping). In the elderly, ginseng intaking was not influenced on any information processing speed and cognitive tasks. These results indicate that ginseng intaking may be useful for information processing speed of the middle-aged, but not for that of the elderly.

Phased Array 트랜스듀서에 있어서 구성 압전소자수의 변화에 따른 초음파 빔 전파 특성의 수치 해석

최상우,이준현 韓國非破壞檢査學會 1999 한국비파괴검사학회지 Vol.19 No.3

일반적인 하나 또는 두개의 압전소자를 사용하는 트랜스듀서에 비하여 다수의 압전소자를 사용하는 어레이 트랜스듀서는 각 압전소자에 가해지는 펄스의 지연시간을 제어함으로써 초음파 빔을 임의의 지점에 집속시킬 수 있고 기계적 구동없이 임의의 방향으로 조향시켜 실시간 주사를 할 수 있는 장점이 있다. 페이즈드 어레이 트랜스듀서의 설계조건은 압전소자의 수, 압전소자의 크기, 그리고 압전소자 사이 간격 등 여러가지가 있으며, 본 연구에서는 그 중에서 압전소자수의 변화에 따른 초음파 빔의 특성을 호이겐스의 원리를 이용한 수평횡파의 시뮬레이션을 통하여 평가하였다. 그 결과 초음파빔은 조향각이 증가할수록 음압이 감소하며, 초음파 빔 특성도 점차적으로 분산됨을 알 수 있었고 또한 초점거리가 증가 할수록 초점에서의 집속효과는 감소하고, 압전소자의 수가 증가되면 집속효과는 향상됨을 알 수 있었다. A phased array is a multi-element piezoelectric device whose elements are individually excited by electric pulses at programmed delay time. One of the advantages of using phased array in nondestructive evaluation (NDE) application over conventional ultrasonic transducers is their great maneuverability of ultrasonic beam. There are some parameters such as the number and the size of the piezoelectric elements and the inter-element spacing of the elements to design phased array transducer. In this study, the characteristic of ultrasonic beam for phased array transducer due to the variation of the number of elements has been simulated for ultrasonic SH-wave on the basis of Huygen's principle. Ultrasonic beam directivity and focusing due to the change of time delay of each element were discussed due to the change of the number of piezoelectric elements. It was found that ultrasonic beam was much more spreaded and hence its sound pressure was decreased as steering angle of ultrasonic beam was increased. In addition, the ability of However, the ability of beam focusing was improved as the number of consisting elements was increased.

Visualization is the process of exploring, transforming and viewing data as images to gain understanding and insight into the data. Visualization in medicine is helpful in understanding human anatomy by presenting the information in a form that is not only pleasing but also easily recognizable as well as in gaining functional attributes of medical systems, such as biomechanical and physiological properties. Medical applications include accurate anatomy and function mapping, enhanced diagnosis. accurate treatment planning and rehearsal, and education/training. The Visible Human data set of the National Library of Medicine, the most complete anatomically detailed. computerized database of the human body ever assembled, has been used for these purposes. In this study, we have visualized the Visible Human Data set with VTK(Visualization ToolKit, Kitware Inc.), IAP(Image Application Platform, ISG Inc.) and Visual C++ 6.0. A motivation of this study is the fact that computer imaging techniques have become an important diagnostic tool in the practice of modern medicine. The 3D visualization system consists of a basic 2D image processing such as filtering, panning, zooming and measuring image as well as 3D image processing such as multiplanar reformatting, surface rendering and volume rendering. The wide-spread use and accessibility of the web have been required to provide the visualization of 3D image on the web. Thus, we have developed web-based medical 3D visualization system that supports World-Wide-Web using VRML and client/server architecture.
