This study was conducted to investigate weight control status and associated factors among health-related major female college students. The subjects consisted of 41 nutrition and 78 physical exercise major female college students. Nutrient intakes, biochemical index, nutrition knowledge (recognition and accuracy), interest of weight control, body satisfaction, self-recognition of health condition, self-evaluated body weight were studied. About 73% of nutrition and 79% of physical exercise major female students were in the normal range of BMI ($18.5{\sim}23$) and 2% of nutrition and 1% of physical exercise major female students were underweight, 10% of nutrition and 6% of physical exercise major female students were obese. There were no significant differences in height and weight by major but %body fat and WHR in physical exercise majors were significantly lower than nutrition major students (respectively p<0.01, p<0.05). Overall, nutrition intakes of subjects were not shown to be appropriate, especially Ca/P of subjects was shown $0.54{\sim}0.64$, fat% out of energy of subjects was shown $24.7{\sim}29.0$ and Na intake was shown above 2000mg. Recognition and accuracy of nutrition were higher than those of physical exercise majors (p<0.001). There were no significant differences in self-recognition of health condition, self-evaluated body weight, satisfaction of body shape by major and weight control attempt. But interest of weight control of attempter was higher than that of no-attempter in nutrition (p<0.05) and physical exercise major students (p<0.01). Significantly negative correlation was found in satisfaction of body and BMI, body fat mass, %bodyfat, WHR. And significantly positive correlation was found in interest of weight control and BMI, %bodyfat, WHR. It was noticeable to see that interest of weight control was positively correlated to accuracy and accuracy was negatively correlated to blood cholesterol level. Therefore, proper nutrition education for female college students is needed in order to improve their weight control-related health.

Gestational age and infant birth weight are influenced by gestational weight gain. This study was aimed to examine the effects of gestational weight gain on pregnancy outcomes. Pregnant women were recruited at two hospitals in Seoul area. Characteristics and dietary intakes of pregnant women were obtained using 24-hour recall questionnaires. Gestational weight gain was categorized as less (Under-gain) than, within (Recommended gain), or greater (Over-gain) than the Institute of Medicine guidelines. Maternal height and pre-pregnancy weight in the over-gain group significantly higher than under-gain and recommended gain group. Mini dietary assessment score of eating bean has significantly higher in under-gain group than recommended gain group and eating kimchi has significantly higher in undergain group than over-gain group. Score of eating fruit was significantly higher in over-gain group than other groups. The mean intake of carbohydrate in the recommended gain group were significantly higher than under-gain group, and mean intake of potassium in the over-gain group were significantly higher than under-gain group. Under-gain group showed the high rate of the preterm delivery and low birth weight infant delivery. However recommended gain group showed 46% reduced risk of preterm delivery (OR = 0.54 CI = 0.30-0.98). Risk of macrosomia increased with increasing gestational weight gain (p for trend < 0.05). In conclusion, pregnancy outcomes were influenced by gestational weight gain. Therefore, these finding suggested adequate gestational weight gain according to BMI for reducing the risk of preterm delivery, low birth weight and macrosomia.

보다 효과적인 색인어 추출 및 색인어 가중치 결정을 위하여 문서의 내용뿐 아니라 구조를 이용하여 색인을 추출하는 연구가 이루어지고 있는데, 대부분의 연구들이 XML 태그의 중요도가 아닌, 문맥상의 단락에 대한 중요도를 계산하는게 일반적이다. 이러한 기존 연구들은 대부분이 객관적인 실험을 통해서 중요도를 입증하기보다는 상식적인 관점에서 단순한 수치로 중요도를 결정하고 있다. 본 논문에서는 웹 문서 관리를 위한 표준으로 자리잡아가고 있는 XML 문서의 태그 정보를 이용한 자동색인을 위하여, 논문을 구성하는 주요 태그를 중요도에 따라 분류하고, 낮은 태그에서 추출된 용어 가중치를 계산하고, 그 가중치로 높은 가중치의 태그에서 추출된 용어의 가중치를 갱신해 가면서 최종 가중치를 계산하는 방법을 제안한다. 보다 객관적인 가중치 결정을 위하여 사용자가 중요하게 생각하는 태그를 실험해 보고 그에 따라 중요도를 분류하여 가중치 계산에 반영한다. 그리고 기존 태그 중요도 결정 방법을 적용하여 계산된 색인어 가중치를 이용한 검색성능과 비교함으로써 본 논문에서 제안한 방법을 적용하여 계산된 색인어 가중치의 효과를 검증한다.

There are several existing studies for the weight estimation of offshore plants. However, most of them were applicable at the pre-FEED (Front End Engineering Design) stage. In this paper, a preliminary study on a method for the weight estimation and calculation of offshore EPC (Engineering Procurement Construction) projects is made for the use at the estimation stage after FEED. Based on literature surveys including ISO (International Organization for Standardization) 19901-5 about weight estimation, we proposes new weight factors and a weight curve. Weight factors defined in this study include MTO (Material Take-Off), estimated weight, FEED maturity factor, allowance factor, and contingency factor. The proposed method utilizes bottom-up approach for weight estimation and it can be used for the weight estimation and calculation of offshore EPC projects at the estimation stage.

Objectives: Obesity is associated with a high mortality risk and impairment in health-related quality of life (HRQOL). The aim of this article is to examine the impact of weight loss on HRQOL and which questionnaires sensitively reflect weight loss effects on HRQOL. Methods: PubMed, Scopus, Research Information Sharing Service, and Korean Studies Information Service System were searched for the studies related to weight loss and HRQOL, published from 2009 to 2018. A total of 28 studies were eligible for inclusion. HRQOL results after weight loss from selected studies were classified and reported according to questionnaires. Results: Twenty-two studies reported statistically significant HRQOL improvements after weight loss and especially, all of studies with weight loss of more than 5% reported HRQOL improvements. HRQOL questionnaires were classified as generic, obesity-related and depression questionnaires. The most commonly used questionnaires were Short-Form health survey 36 (SF-36), Impact of Weight on Quality Life-Lite (IWQOL-Lite) and Beck Depression Inventory (BDI) respectively. SF-36 had a tendency to reflect physical health. IWQOL-Lite score was tended to be changed sensitively according to weight change. Depression questionnaires including BDI reported improvement of depression while mental aspects of SF-36 not changed in same studies. Conclusions: Improvements of HRQOL were noted in studies with weight loss of more than 5%. The main questionnaires for evaluating HRQOL were SF-36, IWQOL-Lite and BDI. It is suggested to use these questionnaires together for evaluating multiple aspects of impact of weight loss on HRQOL.

Objectives: The objective of this study is to evaluate weight change and analyze adverse events in overweight and obese women with polycystic ovary syndrome (PCOS) who were prescribed with Gamitaeeumjowee-tang. Methods: A retrospective chart review was conducted for medical records of patients with PCOS, who were administered with Gamitaeeumjowee-tang for a period of 12 weeks between January 2019 and December 2021. Outcomes were total weight loss/weight loss rate, the percentage of patients who lost more than 5% and 10% of their baseline weight. Adverse events (AEs) reported by patients were evaluated by severity, causality and system-organ classes. Results: A total of sixty-seven patients were included (mean±standard deviation, Age 28.78±5.25 years, weight 76.78±12.84 kg, body mass index 29.2±4.26 kg/m²). The average total weight loss in PCOS patients was 6.57±3.07 kg and the average weight loss rate was 8.55±3.65%. The percentage of patients with more than 5% and 10% weight loss compared to their baseline weight was 86.56% and 25.37% respectively. The analysis of adverse events are as follows: Causality assessment with World Health Organization-Uppsala Monitoring Centre of AEs showed 'Unlikely' was the most common (71.7%) and severity evaluations with Common Terminology Criteria for Adverse Events showed almost all symptoms were mild (98.9%). Conclusions: Gamitaeeumjowee-tang helps to lose weight of PCOS patients, which is overweight or obese, and no serious adverse events have occurred. Additional well-designed clinical studies are recommended.

This study was conducted to investigate the effects of weight control programs on BMI, serum profiles, nutrition knowledge and eating behaviors of adult obese women. The subjects of this study were 33 adult obese women aged 30-65 years residing in Seoul. The weight control program for obese women included nutritional education, cognitive behavioral therapy and exercise for 12 weeks. The weight control experience of the subjects was 60.6%. They preferred physical exercise and diet restriction to weight control and 72.7% of subjects answered that the reasons for wanting to control their weight was health. The BMI of test subjects significantly decreased (p<0.001) from 28.3 to 27.1 after the 12 weeks of the weight control program. In addition, the % body fat significantly decreased (p<0.001) from 36.4% to 34.5% after completion of the weight control program. SGPT levels in the serum were also significantly decreased (p<0.05) after the program. Triglyceride levels significantly decreased from 194.9 mg/dL to 98.1 mg/dL (p<0.01) and the HDL cholesterol level significantly increased (p<0.01) from 55.8 mg/dL to 60.0 mg/dL after completion of the weight control program. Nutritional knowledge and eating behavior scores were significantly increased (p<0.001). In addition, the eating self-efficacy of the subjects was significantly increased (p<0.01); however, the food diversity scores were not changed after the program. These results suggest that the weight control program for adult obese women may be effectively used to promote weight reduction and improve nutritional knowledge and eating behavior.

Recently, the desire for low body weight, which is an abnormal weight construct along with obesity, has become an evident and serious problem in teenagers. In Korea, the desire for low weight is not perceived as an important problem, but it is rapidly expanding relative to the physical changes and developmental issues teenagers experience. The social atmosphere presented through mass media is the key influencer for the increasing low weight occurrence in teenagers. Because thoughts about beauty have changed among people, and since there is apparent blind interest in slim body shape and appearance, already low-weight individuals are attempting to lose weight along with obese persons. Thus, we consider it necessary to guide teenagers toward having correct perceptions with regard to weight and their own body shape, and that a healthy and appropriate weight is beautiful. Therefore, for this study, we investigated body perception, abnormal weight, attitude toward weight control, and factors related to eating behavior among teenage girls, who are considered the at risk group for overt body weight control behavior. Based on this, we have attempted to set in motion a systematic and active nutrition education program that will allow us to increase body satisfaction by educating on nutritional issues related to development, and ultimately, implant healthy body shape perceptions.
