Objectives: The purpose of this study was to find out the relation factors of weight control behaviors, mental health status and body image perception in adolescents and to use basis data of health promotion for adolescents. Methods: This study used data from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V-2, 2011). The subjects were 653 between 12-19 age. Data analysis was done with SPSS/WIN 19.0 using Chi-square test, and Logistic regression. Results: The result is as follows. The case of female adolescents, abnormal perception of body image was significantly higher on weight reduction effort and normal weight, low weight in BMI. The case of male adolescents, abnormal perception of body image was higher on normal weight in BMI. Conclusions: The adolescents tend to do unreasoning weight loss behavior without properly perception for their body image. Therefore, we suggest that adolescents be provided social support for positive body image and be developed perception program with the importance of inner values.

This study attempts to develop a program for obesity prevention and management for students in primary, middle, and high school and was carried based on the program development process as suggested by Ewles and Simnett. Data were collected from September 1st to September 30th, 2000. The study method is as follows: 1) Reviewing the present obesity control programs practiced in primary, middle, and high school (196 schools total) in metropolitan, medium-sized, and small cities, 2) Surveying obesity students'(682 students total) perception of the obesity management in their school. 3) Reviewing the annual plan for obesity in primary, middle, and high schools 4) Analyzing the educational data (CD, VIDEO) for obesity The results are as below: I. The media researched related to obesity were mainly CD and video, aimed primarily primary school students and are biased in nature. 2. The results of how to manage obesity in students: the difficulty of obesity education in the primary school, is the arousal of a sense of shame among obese students and the lack of various educational data are the most. In the middle and high schools, a lack of various educational data, and no time or lack of time were prevailing concerns. Paramount in managing obesity is weight control, as answered by majority of primary, middle, and high school students. The major problem of obesity management is the non-cooperation of children. 3. Asked whether the weight controlling aspect of health care class was helpful or not, 51.4% of primary school students, and 71.6% of middle and high school students answered not. The most popular educational method used in health care class is the computer, with a 56.4% approval rating. Most 43.5% of respondents answered that they wanted the content of obesity management program to focus on how to lose weight. Therefore, based on the results, the obesity management program is constructed to the steps of assessment, planning, implementation, and evaluation. Assessment includes administering surveys on health needs among students and their parents and physique tests. Planning includes the set-up of long term and short term educational goal and the establishment of an operation system. Implementation includes education, exercise, behavior modification, and health service programs. Evaluation includes step-by-step evaluations for obesity reduction. After this study is conducted, the following should be further researched: More practical and systematic obesity management programs should be developed for the evaluation results. In addition, it is important to develop an appropriate media for obesity management the primary, middle and high school students.

The objective of this study is to minimize the weight of a damped anisotropic roto-bearing system considering whirl natural frequency and stability. The system is modeled as an assemblage of rigid disks, flexible shafts and discrete bearings. The system design variables are the crosssectional areas of shaft elements and the properties of bearings. To analyze the system, the polynomial method which is derived by rearranging the calculations performed by a transfer matrix method is adopted. For the optimization, the optimization software IDOL (Integrated Design Optimization Library) which is based on the Augmented Lagrange Multiplier (ALM) method is employed. Also, an analytical design sensitivity analysis of the system is used for high accuracy and efficiency. To demonstrate the usefulness of the proposed optimal design program incorporating analysis, design sensitivity analysis, and optimization modules, a damped anisotropic rotor-bearing system is optimized to obtain 34$ weight reduction.

Combining basal insulin therapy with a glucagon-like peptide-1 receptor agonist (GLP-1 RA) has clear clinical advantages, and is supported by the latest EASD/ADA position statement (1). IDegLira is a once-daily combination of the basal insulin, degludec, and the GLP-1RA, liraglutide, in one pen. The DUAL phase 3 clinical trial program provides important evidence about the efficacy and safety of IDegLira in three different populations of patients with type 2 diabetes (T2D): insulin naïve subjects uncontrolled on oral antidiabetic drugs (OADs), subjects uncontrolled on OAD(s) and a GLP-1 RA, and subjects uncontrolled on OAD(s) and basal insulin. Treatment with IDegLira reduced mean HbA1c to below the EASD/ADA treatment target of 7.0% in all five trials. The mean reduction of HbA1c from baseline ranged from 1.3% and 1.9%. IDegLira resulted in weight loss for subjects uncontrolled on basal insulin, was weight neutral for subjects on OADs and weight gain was minimal (2 kg) for subjects previously treated with a GLP-1 RA. Rates of hypoglycaemia were low across all the trials, particularly considering the level of glycaemic control achieved.

The purpose of this study was to investigate the nutrient intakes, nutritional knowledge, food habits, and lifestyle behaviors of moderately or severely obese children living in the Kyonggi-do area. The subjects in this study were 37 obese children with an obesity index higher than 130% in the forth to sixth grades of elementary school. Anthropometric measurements, 24-hour recall of dietary intakes, and a survey on nutritional knowledge, food habits, and lifestyles behavior were conducted in the 37 obese children (25 boys and 12 girls). The average age, body weight, BMI, and R$\ddot{o}$hrer Index were 12.4 years, 68.6 kg, $29.6kg/m^2$, and 194.9 in boys and 12.7 years, 65.7 kg, $29.8kg/m^2$, and 201.8 in girls, respectively. The percentage of correct answers on nutritional knowledge and nutritional attitude score/max score were 85.8% and 23.0/50 in boys and 87.0% and 17.5/50 in girls, respectively. Except for calcium (85.3%) in girls and calcium (62.7%) and folic acid (83.3%) in boys, the average daily nutrient intakes percentages of nutrients were greater than the DRIs values (107.9~327.3% in boys and 103.0~416.0% in girls). This study showed the existence of some problems associated with obesity, such as higher frequency of skipping breakfast, irregular meal times, unbalanced diet, lack of intake of some nutrients, low nutritional attitude, lack of physical activity, and time management in obese children. These results suggest that a systematic education program including nutritional education on balanced diet, good eating habits and behaviors, and importance of eating breakfast and meal regularity must be emphasized to improve nutrient intakes and food habits in obese children. Obese children also require a more concentrated program that includes physical activity, weight reduction, and weight maintenance strategies to improve their life habits.

The current study investigated the anti-obesity effect of Cissus quadrangularsis extracts (CQR-300) and its molecular action mechanism on obese mice induced high-fat diet (HFD). To induce the obesity, mice were fed a HFD for 6 weeks and then fed HFD only or HFD with CQR-300 at 50 and 200 mg/kg. Then, body weight gain and white adipose tissue weights were measured. We investigated the reduction in body fat and the regulation of fatty acid synthesis was measured by dual energy X-ray absorptiometry and real-time PCR with Western blot, respectively. In vitro study, CQR-300 inhibited pancreatic lipase activity. The CQR-300 treatment was significantly decreased the body weight gain and adipocytes size as well as white adipose tissues weights in HFD-induced obese mice. Furthermore, CQR-300 reduced the body fat and fat mass with regulating of adipose tissue hormones as leptin. Treatment with 50 mg/kg CQR-300 showed effectively lower expression levels of adipogenesis/lipogenesis related genes and proteins such as CCAAT/enhancer binding protein ${\alpha}$ ($C/EBP{\alpha}$), peroxisome proliferator-activated receptor ${\gamma}$ ($PPAR{\gamma}$), Sterol regulatory element binding protein-1c (SREBP-1c), and fatty acid synthase (FAS) in white adipose tissue (WAT) as compared with the HFD fed only mice. These results suggest that the CQR-300 has an anti-obesity effect via inhibition of lipase activity, decrease the body fat mass by regulating the adipogenesis and lipogenesis related genes and proteins in epididymal adipose tissue with evaluate body fat reduce in the HFD-induced obese mice.

고추발효 추출물의 체중감량효과를 알아보기 위하여 여대생을 대상으로 인터넷으로 체중감량을 하는(ID) 그룹과 인터넷과 고추발효 추출물을 섭취하는(IR) 그룹으로 나누어 8주 동안 체중감량 프로그램을 실시하여 체중감량 프로그램 전후와 두 그룹간의 체중, 체지방, 제지방, 기초대사량, 엉덩이, 허리 둘레, 피하지방 두께, 혈당, 혈중 지질의 변화를 관찰하였다. 체중감량 프로그램 전 두 그룹간의 나이, 신장, 체중, 체지방과 제지방 등은 차이가 없었으며, 평소 식이 섭취량도 1944.7$\pm$34.4 kcal와 1864.0$\pm$124.6 kcal로 차이가 없었으며, 체중감량 프로그램 동안 ID그룹의 열량 섭취는 1279.9$\pm$112.0kcal, IR 그룹은 1223.8$\pm$57.1kcal이었다. 8주간의 체중감량 프로그램이 끝낸 후 ID 그룹은 체중, 체지방량, 제지방량, 기초대사량과 BMI가 유의적으로 감소한 반면 IR 그룹은 체중, 체지방율, 체지방량, 제지방량과 BMI가 유의적으로 감소하였다. 두 그룹간의 비교에서 체지방율, 체지방량과 기초대사량이 유의적인 차이를 나타내었는데, 고추발효 추출물의 섭취가 체중에는 영향을 못 미쳤으나, 체지방의 감소를 유발하였으며, 기초대사율의 감소를 방지한 것으로 나타났다. 체중 감량 프로그램동안 ID 그룹의 엉덩이, 허리둘레, WHR은 유의적으로 감소한 반면 IR 그룹은 유의적인 변화를 관찰할 수 없었다. 피하지방두께의 변화에서는 IR 그룹의 복부지방 두께를 제외하고는 유의적으로 감소하지 않았다. 두 그룹간의 비교에서 IR그룹의 복부지방에서 유의적인 변화를 관찰할 수 있어 고추발효 추출물이 주로 복부의 체지방을 감소시킨 것으로 나타났다. 혈액의 변화는 ID그룹의 HDL-콜레스테롤을 제외하고는 유의적인 변화를 관찰할 수 없었는데, 그 이유는 체중감량 프로그램 동안 저지방식이를 권장하였고, 실험시작 전 실험대상자의 초기 혈당 및 혈중 지질 농도가 정상 범위이었기 때문에 혈당이나 혈중지질 변화를 관찰할 수 없었던 것으로 나타났다. 그러므로 체중감량 프로그램에서 고추발효 추출물의 섭취가 체중, 혈당, 혈중 지질의 농도에는 영향을 미치지 못했으나, 체지방 특히 복부지방을 감소시켰으며, 체중감량 시 발생하는 기초대사량의 감소를 방지한 것으로 판단되어진다.
