Obesity in children is a major concern of public health. This study was performed to illuminate its effect on weight control program and the associated factors of obesity-related habits and obesity index in primary school obese children. Weight control program consisted of behavioral modification, nutrition education and exercise during 17 weeks. The sample consisted of treatment group(n=42) and control group(n=41). There was no statistical difference between the two groups in obesity index, socioeconomic status and grade. To asserts the effects of weight control program, the subjects were given pre-test and poet-test such as the measurement of anthropometric values and self-reporting questionnaire. This result of this study were as follows; 1. After weight control program was applied, there was a significant decrease in obesity index among the treatment group. Obesity-related habits score of the treatment group increased significantly, While there wart not much difference between the pre-test and the post-test among the control group. But exercise habit didn't increase significantly in the broth groups. 2. Correlation between obesity-related habits and obesity index were not evident. 3. After application of weight control program, the factors associated with change of eating habit were children's past experience of weight control, motivational change toward weight control program and friends' support for treatment group. The factors associated with change of exercise habit were poet-test motivation score and friends' support. Motivational change toward weight control and pre-test self. efficacy of exercise behavior were counter-related to exercise habit. For change of other obesity- related habits, initial obesity index, motivational change, post-test self-efficacy score of exercise behavior and paternal educational status were closely associated. But post-test self-efficacy score of eating behavior was unrelated.4. Only the factor of experience of weight control was associated with change of obesity index. 5. For the both groups, the factors associated with change of eating habits were post-test self-efficacy of eating behavior and family's support. The factors associated with change of exercise behavior were self-efficacy changes of exercise behavior and friends' support. The factors associated with change of other obesity-related habits were self-efficacy change of eating behavior. Initial obesity index was associated with change of obesity index. 6. The rate of dropouts from weight control program was 28.6% (12/42) in treatment group. Initial obesity index, other obesity-related habits except eating exercise habits, fiend's support were associated with dropout. In conclusion, these results indicated that weight control program in primary school settings was effective. Direct exercise regimen and practice was demanded. In addition to the program itself, much of the success is dependent on the degree of motivation of the children involved and support provided by their parents and friends. Further study need to be performed under the condition that the weight control program is applied for a longer period.

Purpose This study is to evaluate the effect on quality of angiographic image, when the contrast media volume is reduced in Neck angiography by MDCT. Materials and methods Tortal one hundred patients have been examined angiography by MDCT. Fifty patient(A group) of one hundred patients have been examined with 100ml contrast media, the other fifty patients (B group) have been examined with 60ml contrast media and 40ml normal saline. The speed of injection was 4-5cc per second by auto injector. Dual source CT (Definition, Siemens, Erlangen, Germany) and dual auto injector (Optivantage, TYCO) were used for this study. Patients that performed Neck angiography reconstructed 3D image and a radiologist used to 5 scales evaluated visually at the subclavian vein artifact. Results A group-50 person that 100ml contrast media by single auto injection which it uses 1point 0people (0%) and 2 points 2 people (4%) and 3 points 18 people (36%) and 4 points 21 people(42%) and 5 points with 9people(18%) seemed, B group-50 person that 60ml contrast media +Normal saline 40 ml by dual auto injection which they use 1 point 2 people(4%) and 2 points 1 people(2%), 3 points 5 people(10%) 4 points 17 people (34%) 5 points 25 people(50%) seemed. At the result, image quality improved at reduced contrast media. Conclusion The Neck angiography diagnos the carotid artery obstruction or stenosis. When examined 40% it will diminish the contrast media, it will be able to minimize the artifact due to a contrast media abundance in subclavian vein and the possibility of bringing an image quality improvement it was. The CT equipment is developed and rapidity it controls the contrast media quantity which recent existing where also the scan time is coming to be quick gradually it uses well and if it inspects, only image quality improvement it knows, until the side effect which it follows in contrast media decrease it gets and the possibility of putting out it will it thinks.

to define the suitable tube voltage in the gastrointestinal tract examination using barium sulfate. X-ray fluoroscopic unit with undertable tube system, fluoroscopic phantom equivalent to 21.5cm abdomen (CDRH phantom, Nuclear associates, USA), image quality test tool including high contrast resolution patterns and low contrast objects, and w/v 200% BaSo4 of 1mm thickness were used for this study. The test equipments were set up in the order of test tool, fluoroscopic phantom, and barium sulfate on the tabletop, and set the field of view (FOV) of to the mode 23cm(9inch) FOV. We exposed radiation to 5kVp increments from 60 to 125 kVp with automatic exposure controler (AEC) without and with barium sulfate, and then counted the number of high contrast mesh patterns and low contrast holes on the printed images. The number of high contrast mesh patterns and low contrast holes visible should be a minimum of 5 patterns and 6 holes on the printed images. In the test without barium sulfate, the number of high contrast mesh patterns(low contrast holes) was 5(6), 5(6), 5(6), 5(6), 5(6), 5(6), 5(6), 5(6), 5(4), 5(4), 5(4), 4(4), 4(4), 4(4), at 5 kVp intervals from 60 to 125 kVp ,respectively. In the test with barium sulfate, the number of high contrast mesh patterns (low contrast holes) was also 5(5), 5(5), 5(6), 5(6), 5(6), 5(6), 5(5), 4(5), 4(5), 4(4), 4(4), 4(4), 4(4), 4(4), respectively. We propose that the suitable tube voltage in the gastrointestinal tract examination using barium sulfate is 85 kVp before and after, because a low kVp lengthens the exposure time.

김정훈(Jung Hoon Kim),길미경(Mi Kyeong Kil),김기홍(Ki Hong Kim) 대한CT영상기술학회 2009 대한CT영상기술학회지 Vol.11 No.1

Purpose To evaluate the variation of exposure dose and image noise by change of noise index in a study of CT. Materials and methods 64 MDCT, Rando phantom, and photoluminescence dosimeter(PLD) were used for this study. We changed the noise index from 2 to 70 in phantom study with the same condition of abdominal CT, and then evaluated the variation of exposure dose(dose length product and organ dose) and value of image noise according to the noise index. Results In the variation of exposure dose, value of dose length product(DLP) was decreased to 33.3%, 35.5%, 30.3%, 26.2%, 24.3%, in changing from noise index 6 toward 8, 8 toward 10, 10 toward 12, 12 toward 14, 14 toward 16, respectively, and value of organ dose in liver was also decreased to 39.8%, 38.4%, 27.6%, 19.7%, 28.9%, in changing from noise index 6 toward 8, 8 toward 10, 10 toward 12, 12 toward 14, 14 toward 16, respectively. In the variation of image noise, the mean value and standard deviation was 7.01±1.21, 7.04±1.21, 11.29±1.18, 13.37±1.04, 15.66±1.13, 18.30±1.60, 20.19±1.49, in noise index 4, 6, 8, 10, 12, 14, 16, 18, respectively. Conclusion The variation of exposure dose was shown irregularly according to regular changing of noise index, and the most variation was between noise index 6 and 16 used in clinic mainly. The value of image noise was slightly higher than that of setting noise index in all measured range, the value of that between noise index 2 and 14 was constantly shown standard deviation with 1.5 and less.
