The purpose of this study was to evaluate the effectiveness of weight control software program. Weight control software program, which we developed, is composed of personal information, advices related to preventing obesity, weight-loss plan, food record, exercise record and evaluation. Twenty two obese women participated in this study. All subjects randomly divided into Software Program (SP) group and Nutrition Education(NE) group. Mean energy intake during the treatment was 1120㎉(CHO:60%, PRO:15%, FAT:26%)in SP group, and NE group consumed 13244㎉(CHO:59%, PRO:15%, FAT:26%). The SP group lost 1.4±1.7㎏ of body weight and the NE group lost 1.9±1.2㎏. Percent body fat decreased 0.7±1.1% in SP group, and 0.8±1.2% in NE group. Regarding the changes of body weight and percent body fat, there were no significant difference between SP group and NE group. The SP group experienced a significant decrease in Total-cholesterol (36.8±32.5㎎/dl), LDL-cholesterol (31.6±33.3㎎/dl) and Triglyceride (21.5±22.4㎎/dl). The NE group experienced no difference between pre and post values. The changes of serum lipids showed no difference between SP group and NE group except LDL cholesterol. The results of this study suggest that managing weight through the weight control software program have the same effect as through nutrition education.

Electrical monitoring of the nervous system offers the potential for the detection of injury, intraoperatively. The relationship of MEP(Motor Evoked Potential) and SEP(Sensory Evoked Potential) taken in 30 rats before and after spinal cord injury is reported. MEP was obtained from distal portion to the site of spinal cord injury by electrical stimulation of the cerebral motor cortex after insertion of a ball electrode in the cerebral motor cortex. SEP was collected at the cerebral somatosensory cortex during the sciatic nerve stimulation. Experimental animals were divided into a 20g㎝ spinal cord-trauma group and 50g㎝ spinal cord-trauma group. Changes of cardiopulmonary function after cerebral motor cortex stimulation and pre-and post-injury MEP and SEP were obtained at constant time interval. The results were follows : 1) Significant changes in blood pressure, pulse rate, and respiratory rate were noted to be elevated after stimulation of cerebral motor cortex and these were returned to normal in 10 minutes after stimulation. 2) MEP in control group showed that the latency was 8.6±1.54msec and the amplitude was 20.60±3.2㎶. In MEP of 20g㎝ spinal cord trauma group, the latency was increased to 30% (11.26±1.76msec) compared to control group at 10 minutes after the injury and the amplitude was decreased to 29% (14.60±2.99㎶). The latency was slowly decreased with the passage of time, to 21% increase. (10.42±1.84msec) at 1 hour after injury but the amplitude was not changed. In 50 g㎝ spinal cord-trauma group the latency was decreased to 75%(4.9±1.52㎶) compared to control group. With the passage of time, no change was revealed in latency but amplitude was decreased. The amplitude was decreased to 80%(4.00±1.49㎶) compared to control group. Change of MEP was marked in 50g㎝ spinal cord-trauma group. With the passage of time MEP was slightly improved in 20g㎝ spinal cord-trauma group but deteriorated in 50g㎝ spinal cord-trauma group. 3) The latency of SEP in control group was 12.22±0.7msec and the amplitude of those was 20.00±2.21㎶. No significant statistical change was recorded in the SEP of each spinal cord-trauma group compared to control group. MEP might be more important indicator than SEP in estimation and evaluation of the functional change of spinal cord injury.

The aim of this study was to evaluate the effects of 3D-Relax Diet; a proprietary formation containing hydroxycitrate(233mg/g), carnitine(150mg/g); and capsaicin (150mg/g); on body weight, % body fat, fat mass, lean body mass, Resting Metabolic Rate(RMR), body circumference, skinfold thickness, serum glucose and lipid level. Nineteen female college students participated in this 4 weeks weight control program. All subjects were randomly assigned to the Sang sik(S) group or Sang sik & 3D-Relax(3D) group. Mean energy intake of 3D group was l,523.1±300.2 ㎉(carbohydrate: 66.3%, protein: 18.7%, fat: 15.0%) and S group consumed 1,464.8±142.1 ㎉(carbohydrate: 65.1%, protein: 19.0%, fat: 15.9%) during program. The 3D group lost 3.1±1.3 kg of body weight, 2.5±l.4 kg of fat mass, 0.6±1.2 kg of lean body mass and 16.8±183.3 ㎉/d of RMR and the S group lost 1.8±1.0 kg of body weight, 1.1±1.1 kg of fat mass, 0.8±0.3 kg of lean body mass and 19.1±181.9 ㎉/d of RMR. There was no significant differences in the loss of lean body mass and RMR between two groups, however, the total body weight and the fat mass were significantly decreased in the 3D group compared to the S group(p<0.05). The 3D group experienced a significant reduced hip size, total-cholesterol and HDL-cholesterol, however, the change of these between groups were not significantly different. There were no differences in the change of body circumference, skinfold thickness, serum glucose and lipid. These results suggest that the intake of 3D-Relax Diet(hydroxycitrate, carnitine, and capsaicin) during the weight control program decreased energy intake, fat intake and total body weight especially fat mass and those effects are presumably linked to the prevention of RMR decline and the inhibitory effects on lipogenesis.

The purpose of this study was to identify the change of the dietary pattern, food craving in accordance with menstrual cycle among women with the premenstrual dysphoric disorder(PMDD) and women with no premenstrual symptoms(Non-PMS). The 24 subjects were divided by two groups, PMDD group and Non-PMS group. And the change of dietary pattern and food craving were measured for 4 weeks according to the menstrual cycle. The frequency of meal, the amount of meal and the change of palatability of meat intake, fatty food, carbonate drinks, fruit, confectionery and caffeine containing beverage were more significantly increased in luteal and menstrual phase than follicular phase without regard to PMDD group and Non-PMS group, but there were no statistically difference between groups. The change of palatability of vegetable & alcohol were no difference among the phase without regard to PMDD group and Non-PMS group, and there were no statistically difference between groups. Above the findings showed that the change of women's dietary pattern has connection with the change of menstrual cycle. It is considered that unconsidered variables in this study could be applied for the therapy of premenstrual symptom or management method in connection with variable related to menstrual cycle the systematic study is requested.

This study was conducted to investigate the postprandial effects of corn peptide(CP) on lipid metabolism. Sprague-Dawley(S.D) male rats were divided into four groups & fed same amount of olive oil(1.0g) & different quantity of CP(0g, 0.lg, 0.2g, 0.3g) to examine the postprandial effects of lipoprotein concentration. Post triglyceride(TG) concentrations of the CP 0g & CP 0.1g groups significantly increased compared with the pre values. However, There were no significant changes in CP 0.2g & CP 0.3g groups. However, we can not observe the significant change of cholesterol concentrations between pre & post values in every four groups. These results suggest that the ingestion of CP inhibited the absorption of triglyceride by binding with bile salts in the intestine, therefore, the concentration of chylomicron`s triglyceride was not significantly increased.

The facts of job satisfaction and their perceived importance among elementary school foodservice dietitians were assessed. The survey instrument consisted of three parts: the job satisfaction survey was used to measure facets of job satisfaction and the level of total satisfaction; perceived importance questions for corresponding job facets; and demographic items. A survey of school food service operations was undertaken and detailed information was collected from 170 dietitians. The collected data were processed using the SPSS package program for descriptive analysis and analysis of variance. School foodservice dietitians' importance and satisfactions scores on their job and working environment were 4.25 and 2.83, respectively. The respondents rated the subscales of 'communication' and 'nature of work' the highest and the subscales of 'pay' and 'working environment' the lowest. The results of facet satisfaction scores and corresponding perceived importance scores were paired to be plotted on the Importance-Performance Analysis Grid. IPA grid was used to provide a strategy for food service managers to counteract dietitian dissatisfaction.

장은재,임경아,한용봉 한국식품영양학회 1999 韓國食品營養學會誌 Vol.12 No.2

영양교육이 체중조절에 미치는 영향을 알아보고자 여대생을 대상으로 영양교육을 시킨 그룹과 시키지 않은 그룹으로 나누어 8주간 체중조절 프로그램을 실시하여 체중, 체질량 지수, 체지방 비율, 표준체중 비율 등은 두 그룹 모두 유의적으로 감소하였다. 영양교육을 받은 NE group은 영양 교육을 받지 않은 DO group보다 크게 감소하였다. NE group은 8주 동안 꾸준하게 감소되는 반면, DO group은 4주 동안 감소하였지만, 스스로 조절하는 5주부터 8주 동안에는 변화가 없었다. NE group은 체중조절 프로그램이 진행되는 동안 교육의 효과로 열량 및 탄수화물, 단백질과 지방의 섭취량이 유의적으로 감소하였다. DO group은 열량 섭취량 및 탄수화물, 단백질과 지방이 처음 4주 동안 감소하였으나, 5주부터 8주 동안은 약간씩 증가하였다. 혈청 지질의 농도는 NE group이 Total-cholesterol과 LDL-cholesterol이 유의적으로 감소하였고, DP group의 triglyceride는 처음보다 유의적으로 증가되었다. 영양교육을 포함한 체중조절 프로그램은 체중, 체지방 및 혈청 지질농도를 감소시켰고, 감소 수준을 오랫동안 유지할 수 있었다. This study attempted to evaluate the effectiveness of nutrition education on a weight control program. The major components of nutrition education in this program, held for 8 weekly sessions, were the general nutrition information about the diets, especially low fat, high carbohydrate hypocaloric diets, methods of increasing physical activity, strategies for the maintenance of proper body weight, and other information related to the prevention of obesity. Twenty five female college students participated in this program. All subjects were randomly assigned to the Nutrition Education(NE) group or the Diet Only(DO) group. Mean energy intake of the NE group was 1,230㎉(CHO:61%, PRO:15%, FAT:24%), DO group consumed 1,472㎉(CHO:58%, PRO:16%, FAT:26%). The NE group lost 3.3±0.7㎏ of body weight. In contrast, the DO group lost 1.8±0.6㎏. The NE group experienced a significant decrease in cholesterol, LDL-cholesterol level, however, the DO group significantly increased in triglyceride. The results of this study suggest that progressive nutrition education in a weight control program might reduce body weight and serum lipids concentration.
