The purpose of this study was to determine the therapeutic effect of slope changes of the treadmill with body weight-supported training on gait characteristics in patients with hemiplegia. The volunteered subjects were divided into 3 groups based upon slope changes: control group (0° incline), 7° group (7° incline), 12° group (12° incline), They were trained the body weight-supported treadmill training (BWSTT) for 8 weeks. All subjects were supported up to 40% of their body weight on the treadmill training and the support was gradually decreased to 0~10% as the subjects were adapted to the training. There were significant improvements of walking velocity, step length of the affected side, the asymmetry ratio of step length in 7° group (57.80 cm/s, 67.25 cm, .14), 12° group (71.00 cm/s, 71.00 cm, .11) than control group (40.62 cm/s, 55.00 cm, .74) (p<.05): there were no differences between group 7° and 12° group in the all outcomes (p>.05). Both 7° group and 12° group scored higher than the control group in those outcomes and finally the effects of slopes changes of the treadmill were effective on gait characteristics of patients. But it s till remains undetermined what degree on the treadmill might be better to train the hemipareric patients. Therefore, more studies are required to look into minutely the changes of slopes of the treadmill influencing on gait characteristics.

Di-n-butyl phthalate (DBP), diisononyl phthalate (DINP) and di-(2-ethylhexyl) adipate (DEHA) are ubiquitously distributed chemicals that are widely used as plasticizers and also found at low levels in foods. The aims of this study were to determine whether perinatal exposure to DBP, DINP and DEHA could alter normal patterns of neonatal development. Dams were provided with pulverized soy-free diet containing 20, 200, 2,000 and 10,000 ppm of DBP, 40, 400, 4,000 and 20,000 ppm of DINP, or 480, 2,400 and 12,000 ppm of DEHA from gestational day 15 to postnatal day 21. Exposure to the high doses of DBP, DINP and DEHA during gestational period significantly decreased food consumption and body weight gain of dams. These chemicals reduced neonatal body weight as well as that of the after maturation. Also, exposure to DINP of all the doses used and the higher doses (2,400 and 12,000 ppm) of DEHA decreased AGD at PND 1 in male neonates, though that to DBP did not affect AGD in males. In female neonates, an increase in AGD was observed in DBP- and DINP-exposed animals at the highest doses. Moreover, these chemicals affected survival rate of pups at PND 5, and delayed onset of eye opening in all chemical-exposed groups at PND 17. These results suggest that perinatal exposure to these chemicals may affect the normal development and / or growth of offspring.

In architecture, constitutions of space are subjected to the structural material and interior finishing material. Interior environment can exert a great effect on people by means of space constitution. In this study the constitution of space was set to consider five materials: control, wood, steel, wire mesh, and concrete structural material. In this study, experiments with mice, were carried out on condition of each living environment with different living environment using control, wood, steel, wire mesh and concrete structural material. The experiments with mice were made by five-month-old mice(BALB/C) with about 15 grams weight. In order to evaluate the adaptability of the target mice, such variables as body weight, food consumption, and water consumption were monitored against living environment for normal BALB/C mice during the same period. The weight, total foods, and total water consumption were measured under the living environments for 55 days with 2~3 days intervals. To test five different living environments, i.e., control, wood, steel, wire mesh and concrete, 5 mice were allocated for each group. According to the results of this study, the case of wood living environment resulted in a gain in weight with statistical significance. The other side of steel, wire mesh and concrete showed a slight decrease for weight. The weight variation of the experimental mice was assumed under five different living environments that resulted from the stabilized environmental conditions such as the wood living environment.

The purpose of this study was to investigate the effects of eating habits and control of overeating of obese children on the body weight control program. The program included nutritional education, psychotherapy and physical exercise on weekly session for 9 months. The results of this study were as follows. Participants of the study involved 30 obese children attending elementary school. The average age of the children was 11.78 years, mean height and weight were 146.22cm and 50.61kg. The average BMI and body fat contents were 24.06 and 30.49% respectively and WHR of the children was 0.87. There was a significant difference between boys and girls' BMI(25.18, 23.31, p<0.01). As a result of the eating habits test, 50% of the subjects showed low level of regularity of diet, and 76.7% of the subjects showed high level of balanced diet score. Large portion(83.3%) of the subjects had high level of healthy behavior score. WHR of girls significantly decreased from 0.86 to 0.82(p<0.01) after the body weight control program. There were no significant differences in serum components of the obese children after the program. When regarding the score of eating habits in relation to obesity indices, the WHR significantly decreased(p<0.05) in a group of children with high eating habits score. Also in the group of overeating controls, significantly decreased WHR(p<0.05). In the results of correlation analysis, body weight was positively correlated with BMI(r=0.624), the level of total cholesterol(r=0.5109) and HDL cholesterol(r=0.5088). The score of healthy behavior was positively correlated with height(r=0.5286) and negatively correlated with the level of LDL cholesterol(r=0.3555) and WHR(r=0.4028) These results suggest that the body weight control program must be considerate of the different groups of children with different scores in the eating habits and overeating controls test.

평균 연령 10.8세인 비만 아동 17명을 대상으로 12주간 영양교육을 중심으로 한 체중조절 프로그램을 실시한 결과 비만도와 BMI에서는 유의적인 변화를 보이지 않았으나 허리둘레 및 엉덩이 둘레가 유의적으로 감소하였고, HDL-콜레스테롤이 유의적으로 증가하였다. 지방 조직 분비 호르몬-resistin, adiponectin, leptin의 수준은 체중조절 프로그램 실시전과 후에 유의적인 차이를 보이지 않았다. Resistin과 leptin의 변화량은 BMI 변화량과 양의 관계를, adiponect의 변화량은 음의 관계를 나타내 체위와의 상관성을 보여주었으나 본 연구만으로 이들 호르몬들과 체위변화와의 상관성을 규명하기에는 부족했다. 또한 체중조절 프로그램 후 열량 외에 무기질과 비타민 등 대부분의 영양소 섭취가 감소하여 체중조절 프로그램을 진행할 때 열량섭취는 줄이면서 미량 영양소의 섭취는 유지할 수 있게 올바른 식품을 선택할 수 있도록 하는 교육이 강화되어야 할 것이다. 본 연구는 비교적 단기간의 체중조절프로그램의 효과를 살펴본 것으로서, 본 연구결과를 토대로 앞으로 영양교육의 내용을 수정하고, 체조성 변화에 대한 연구를 강화하며 좀 더 장기적인 체중조절 프로그램을 수행한다면 아동 비만 치료에 더 좋은 효과를 낼 수 있을 것이라 사료된다. 또한 비만과 체지방분비호르몬의 상관성에 대한 후속연구도 필요한 것으로 본다.

목적 : 초등학교 학생들이 메고 다니는 책가방 무게와 종류에 대해 알아보고, 체중에 비례한 책가방 무게의 비율과 책가방무게로 기인하는 통증의 경험을 조사 하는 것이다. 연구방법 : 본 연구는 강원도 원주시에 소재한 1개의 초등학교에서 513명의 학생을 대상으로 실시하였다. 등교시 학생들의 책가방 무게와 몸무게, 책가방의 유형, 사물함 사용 여부, 통증 유/무를 조사하였다. 책가방 무게는 저울로 측정하였고 학생들의 몸무게는 학교 자료를 이용하였으며, 그 외의 정보는 인터뷰를 통하여 자료를 수집하였다. 자료 입력 및 분석은 SPSS 윈도우 버전 12.0을 사용하였다. 결과 : 실험에 참여한 학생 중에서 남녀 학생 비율은 여학생이 225명(43.86%), 남학생이 288명(56.14%)이였다. 사물함을 사용하는 학생은 388명(75.63%)이였고, 사물함을 거의 사용하지 않거나 사용하지 않는 경우는 125명(24.37%)이었다. 책가방으로 인해 통증을 경험한 학생은 226명(44.05%)이었으며, 책가방 유형은 양쪽 어깨에 메는 유형이 478명(93.18%), 한쪽 어깨에 메는 유형이 11명(2.14)%이였고, 손으로 드는 유형이 23명(4.48%)이였다. 바퀴가 달린 가방을 사용하는 학생은 단 1명뿐(0.19%)이었다. 학생들이 들고 다니는 평균 책가방의 무게는 3.91 kg으로 학년이 올라 갈수록 증가하였으며 체중에 대한 평균 책가방 무게의 비율은 12.30%였다. 결론 : 본 연구를 통하여 초등학교 학생들의 책가방 무게가 체중에 비해 무거웠으며 통증과의 상관관계는 없었다. 과중한 책가방무게가 잠재적으로 학생들의 근골격계통에서의 문제를 야기 시킬 수 있기에 이를 예방하기 위한 교육적, 인간공학적, 사회와 부모의 관심이 필요하다고 사료된다.

This study was peformed to investigate effect of feeding experimental mixture containing chitosan, hibiscus extract and L-carnitine on body weight and lipid metabolism in rats. Forty-eight male rats(Charles River CD) of eight weeks old and weighing 336.5±2.3g were raised for five weeks with high fat diet(40% fat as calorie) to induce obesity. After induction of obesity, rats weighing 560.4±5.6g were blocked into four groups according to body weight and raised for eight weeks with diet containing either 0.09%(+1D group), 0.9%(+10D group) or 4.5%(+50D group) of experimental mixture. Aspartate aminotransferase(AST) and alanine aminotransferase(ALT), total protein and albumin were normal levels in plasma. Body weight gain and epididymal fat pad weight were lower in experimental mixture groups than control group However, weights of perirenal fat pad and brown adipose tissue were not significantly different among all groups. There was no significant difference in plasma and hepatic lipid levels among all groups. Liver citrate lyase and camitine acyltransferase activities were not significantly different among all groups, however, citrate lyase activity was tended to be decreased with increasing experimental mixture level in diet. Fecal total lipid and total cholesterol excretions were highest in +50D group, and triglyceride excretion was highest in +1D group. in conclusion, intake of experimental mixture containing chitosan, hibiscus extract and L-camitine was effective in reducing body weight and body fat, and its inhibitory effects might lead to obesity improvement.

Body weight support treadmill training is a new and promising therapy in gait rehabilitation of patients with hemiplegia. The purpose of this study was to identify the effects of body weight support treadmill training on gait and standing balance in patients with hemiplegia. Eighteen patients with hemiplegia participated in the study. A 10 m-timed walk test, measurements of step length and standing balance score were administered. Intervention consisted of body weight support treadmill training five times a week for 2 weeks. The data were analyzed by paired t-test. Body weight support treadmill training scoring of standing balance, step length and 10 m-timed walk test showed a definite improvement. Body weight support treadmill training offers the advantages of task-oriented training with numerous repetitions of a supervised gait pattern. The outcomes suggest that patients with hemiplegia can improve their gait ability and standing balance through body weight support treadmill training.

The purpose of this study was to investigate the effects of parent's nutritional education for body weight control of obese children. The weight control program include nutritional education, exercise and behavioral therapy during 20 weeks. Twenty- three children completed this program, the children were divided into two groups by control group and parent's nutritional education group. Parents volunteered to participate in a 4 week nutritional education program for parents and contact the therapist at least once per week to help their obese children. The results from this study were as follows. There were not significant differences in anthropometric values after weight control program between two groups. Triglyceride(TG) level in serum was decreased after weight control program in group of parent's nutritional education, but there was not significant difference. Parent's nutritional education did not add improvements in weight and fitness, but the children of parent's nutritional education group showed increased general self-worth upon completing the program(p<0.05) whereas the other children of control group did not. Also there were desirable changes of exercise and life habits in group of parent's nutritional education group.

The purpose of this study was to investigate the effects of body weight control program for obese children. The program included nutrition education, exercise and behavioral therapy for 20 weekly sessions. The results from this study were as follows. The average age of the subjects was 11.3 years, mean height and weight were 146.12cm and 59.42kg respectively. After weight control preogram, Rohrer index(Rl) was significantly decreased from 186.78 to 182.72(p<0.001). There were not significant differences in body fat percent(%) and fat weight(kg) but it showed decreased pattern. In the change of body circumferences, chest circumference was significantly increased(p<0.01) and mid-arm circumference was significantly decreased(p<0.001) after weight control program. Triglyceride(TG) level in serum was significantly decreased from 113.79 to 80.36(p<0.01) and total cholesterol and LDL-cholesterol level showed declind pattern. The food habits of obese children significantly improved(p<0.001) after weight control prgram. And there were desirable changes of food attitude, excercise and life habits. These results suggest that weight control program including nutrition education, exercise and behavioral therapy may be effective for helping obese children.

In motor learning, the relative frequency of external feedback is the proportion of external feedback presentations divided by the total number of practice trials. In earlier studies, increasing the percentage of body weight loading on the affected leg of hemiplegic patients, external feedback was continuously produced as the patient attempted to perform a movement. This feedback was produced to enhance the learning effect. However, recent studies in nondisabled populations have suggested that compared with 100% relative frequency conditions, practice with lower relative frequencies is more effective. My study compared the effect of 100% relative frequency conditions with 67% relative frequency conditions to determine what effect they exerted on motor learning for increasing the percentage of body weight loading on the affected lower limbs of patients with hemiplegia. Twenty-four hemiplegic patients were randomly assigned to one of two experimental groups. Each group practiced weight transfer motor learning on a machine. During practice, visual feedback was offered to all subjects. The experiment was carried out with full visual feedback for patients in group one but only 67% visual feedback for patients in group two. The percentage of loading on the affected leg was recorded four times: before learning (baseline value), immediately after learning, 30 minutes after learning, 24 hours after learning. The results were as follows: 1. In the 100% visual feedback group, the percentage of loading on the affected leg increased significantly in all three testing modes over the baseline value. 2. In the 67% visual feedback group, the percentage of loading on the affected leg increased significantly in all three measurements. 3. Immediately after learning, the learning effect was not significantly different between the two groups, but was significantly greater after both the 30 minutes delay and the 24 hours period. These results suggest that the 33% reduction in the provision of visual feedback may enhance the learning effect of increasing the percentage of body weight loading on the affected leg in patients with hemiplegia.
