Obesity is a major public health problem worldwide, with several methods having been proposed as a means of weight loss. If diet, exercise, and medication are insufficient, a healthcare professional may suggest weight loss treatments, including bariatric surgery or medical devices. Antiobesity medical devices are an option for patients who do not want to undergo bariatric surgery. Compared with bariatric surgery, medical devices have the advantage of being reversible and easier to operate. The U.S. Food and Drug Administration (FDA) regulates medical devices, including those used for weight loss and weight management. This article provides an overview of the FDA-regulated weight loss and weight management devices.

본 논문에서는 큰 크기의 심층 신경망을 압축하기위해 네트워크 수준의 가중치 공유방법인 Global Weight 패러다임을 최초로 제시한다. 기존의 가중치 공유방법은 계층별로 가중치를 공유하는 것이 대부분이었다. Global Weight 는 기존 방법과 달리 전체 네트워크에서 가중치를 공유하는 효율적인 방법이다. 우리는 Global Weight 를 사용하여 학습되는 새로운 컨볼루션 연산인 Global Weight Convolution(GWConv)연산과 GWConv를 적용한 Global Weight Networks(GWNet)을 제안한다. CIFAR10 데이터셋에서 실험한 결과 2.18 배 압축에서 85.64%, 3.41 배 압축에서 85.46%의 정확도를 보였다. Global Weight 패러다임은 가중치 공유가 궁극적으로 풀고자 했던 중복되는 가중치를 최소화하는 획기적인 방법이며, 추후 심도 있는 연구가 수행될 수 있음을 시사한다.

Purpose: To explain the concept of postpartum weight retention and to analyze factor effect on it. Method: A total of 20 studies related postpartum weight retention were selected in the year of 1988-2001 and analysis was done. Result: A demographic factor like parity, age, social and economic level and life style such as exercise, diet, breast feeding are influential factor on postpartum retention weight. But parts of them don't agree the same results. Meanwhile, in some studies, psychological factor like women's self esteem related to postpartum retention weight, body image change, depressing is found to be very related. As a result, postpartum overweight gain could be a bad factor of physical and mental health. In Korea, we have few studies related to them. Conclusion: It is required to do many-sided and deep studies about aspects of postpartum retention weight and the factor that effect on it. Postpartum retention weight should be approached by controling weight from the period of pregnancy. And it would rather be researched through individual approach considered women's various demographic, social-cultural and physical level than be required standardized level of weight gain.

Purpose: The purpose of this study was to provide basic data for the development of weight control programs to maintain and promote healthy behavior in women college students by identifying their weight control behaviors and factors that influence these behaviors. Method: Data were collected from 300 women student participants and were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression with the SPSS 18.0 program. Result: Weight control behavior showed a significant difference according to participants' gender role identity type. Weight control behaviors were correlated with self-efficacy, body image, objective BMI, and ideal BMI. Factors influencing weight control behavior were self-efficacy (${\beta}$= .449, $p$<.001), secret method for weight loss (${\beta}$= .181, $p$<.001), monthly allowance below 200,000 won (${\beta}$= .156, $p$= .006), weight control support from others (${\beta}$= .124, $p$= .013), eating breakfast (${\beta}$= .119, $p$= .015), and age (${\beta}$= .113, $p$= .023) with R-sq. value of 45.3%. Conclusion: The results of the study indicate that development of interventions for weight control behavior and health education for college women should reflect identified factors influencing weight control behavior and gender role identity.

Correlations among body weight and sociodemographic factors, including life - style were tested as social determinants of health in a sample of 5,201 adults in Korea. The aim of this study was to determine the extent to which sociodemographic variables and life-style associated health behaviors explain body weight distribution. A second aim was to explain the relation of body weight and health status to stress the importance of body weight as an early risk indicator of health status. The canonical correlation between the weight distribution(underweight and overweight) and the independent variables was 0.29, 17% of the total variance was explained. Perceived health level represented the highest contribution(canonical coefficient 0.82) to body weight. Sociodemographic factors such as sex, economic status, and life-style factors such as smoking, exercise, regular meais and sleep showed comparatively high contributions to body weight. The relevance of body weight for health status including the rate of chronic disease and the rate of medical utilization was significant. Especially, underweight was clarified as being mere important than overweight to morbidity level and medical utilization. These findings suggest that perceived body weight is an important indicator of health status and is thus a valuable variable to be considered for nursing intervention and health education related to the promotion of health.

The purpose of this study was to investigate the difference in dietary attitudes, dietary behaviors and health-related lifestyles among Korean college students (392 males, 808 females) participating in a web class of nutrition education. This cross-sectional survey was conducted by a self-administered questionnaire and data was analyzed by SPSS program. Most female subjects with weight-control attempt had eating habit problems such as overeating and food jags. The female subjects with weight-control attempt showed significantly higher rate of skipping dinner compared to those without weight-control attempt. As for frequency of exercise, the subjects with weight-control attempt exercised more frequently compared to those without weight-control attempt. In subjects, weight-control attempt was significantly associated with exercise. Nutrient adequacy ratio and mean adequacy ratio of the subjects with weight-control attempt were significantly lower compared to those without weight-control attempt. These results suggest that skipping dinner or exercise might be used as weight-control methods in Korean college female students participating in a nutrition education class via the internet.

Sixteen local sheep (8 male + 8 female) of about six months old with average live weight 10.78 $({\pm}1.11)$ kg were allocated into four treatments. The treatments (T) are : $T_0$ = Restricted grazing without concentrate; $T_1$, $T_2$ and $T_3$ = Grazing + 100, 200 and 300 g concentrate per sheep daily. Live weight of grazing (7.30 hrs daily) sheep was recorded in each week. The uncastrated male sheep were slaughtered for carcass and non-carcass parameters. Statistically significant (p < 0.05) differences were observed in live weight gain (g/day) among the treatments ($T_0=15.71$; $T_1=22.66$; $T_2 =32.66$ and $T_3=40.47$). The dressing % were : ($T_0=32.75$, $T_1=38.50$, $T_2=36.90 $ and $T_3=37.75$). The warm carcass weight represented 37.21% of live weight. Significant (p < 0.01) correlation were observed for live weight with carcass weight (r = 0.99) and dressing % (r = 0.88). Concentrate supplement increase live weight gain in sheep on grazing. Live weight is a good indicator to assess carcass characteristics.

Accurate weight prediction methods are an essential of the ship design in both ship cost managements and performance satisfactions. When no parent or similar ships are available, an adequate method of the ship weight estimating is required. In this study, there was carried out to develop the ship weight estimating method for the preliminary design phase. The weight estimating methods were first surveyed by the references and summarized their characteristics. The weight estimation method by statistical approach was developed for the container ship because the containerized transportation markets is gradually growing and ship's size and loading capacity are rapidly enlarged. The correlation analysis and the multiple regression analysis were used for developing the weight estimating method. As a results of evaluating the developed method, the error ratio of the variation between estimated weight and ship's data was about 5%. And it was only 1% difference with the calculating weight of conceptual design results by shipyard design team that the estimating weight of ultra-large container ship was predicted by the developed method.

Purpose: This study aimed to evaluate weight changes in women during the period of TAC (docetaxel-doxorubicin-cyclophosphamide) chemotherapy after breast surgery and the differences in weight changes by disease characteristics among Korean women with breast cancer. Methods: The design of this study was retrospective survey research. The subjects of this study were 130 patients with fully completed TAC chemotherapy between January 2012 and April 2015. Body weight before their operation, and at 3 weeks, 6 weeks, 9 weeks, 12 weeks, 15 weeks, and 18 weeks after surgery, as well as general and disease characteristics, were reviewed via their medical charts. Results: The mean age of the patients was 51.2 years. The preoperative (baseline) mean weight was $59.4{\pm}8.44$. Significant weight losses were observed in the initial (1st 3 week) period of TAC chemotherapy compared to the baseline and significant weight losses were observed with the exception of the period 6 weeks after breast surgery. There were significant differences in mean weight changes according to the stage of breast cancer, radiotherapy, and hormone therapy among disease characteristics. Conclusion: It is necessary to study weight changes after breast surgery for the long periods of TAC chemotherapy. Through the accumulated results of studies, nursing programs for breast cancer patients must be developed for the prevention of weight gain in the periods of TAC chemotherapy.

The purpose of this study was to set up an effective marketing strategy targeting college women by researching the relationship between weight control behavior and satisfaction with fit of apparel. The results showed that 1) 85.5% of the college women participated in weight control behavior, and 53.5% of them wanted to lose more than 3kg of their weight, 2) both body cathexis and fit satisfaction of college women were generally low. College women were less satisfied with their body and fit of apparel according to the increase of weight control degree. The weight control parts and unsatisfied body parts were almost matched : thigh, abdomen, hip, calf, and weight. The unsatisfied fit of apparel parts were also found to be thigh, hip, abdomen, crotch, pant length that matched each parts, 3) fit satisfaction of neckline, shoulder, midriff, hip, crotch, thigh, calf, and skirt length decreased according to the increase of weight control degree, and 4) weight control group which wanted to lose weight at neck, shoulder, arm, breast, waist, abdomen, hip, thigh, and calf also had low fit satisfaction of neckline, shoulder, armhole, sleeve, breast, waist, abdomen, midriff, hip, thigh, crotch, calf, and skirt length in clothing.
