Purpose: This study evaluated the changes in nutritional status based on quality of life (QoL) item-level analysis to determine whether individual QoL responses might facilitate personal clinical impact. Materials and Methods: This study retrospectively evaluated QoL data obtained by the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30) and Quality of Life Questionnaire-Stomach (QLQ-STO22) as well as metabolic-nutritional data obtained by bioelectrical impedance analysis and blood tests. Patients were assessed preoperatively and at the 5-year follow-up. QoL was analyzed at the level of the constituent items. The patients were categorized into vulnerable and non-vulnerable QoL groups for each scale based on their responses to the QoL items and changes in the metabolic-nutritional indices were compared. Results: Multiple shortcomings in the metabolic-nutritional indices were observed in the vulnerable groups for nausea/vomiting (waist-hip ratio, degree of obesity), dyspnea (hemoglobin, iron), constipation (body fat mass, percent body fat), dysphagia (body fat mass, percent body fat), reflux (body weight, hemoglobin), dry mouth (percent body fat, waist-hip ratio), and taste (body weight, total body water, soft lean mass, body fat mass). The shortcomings in a single index were observed in the vulnerable groups for emotional functioning and pain (EORTC QLQ-C30) and for eating restrictions (EORTC QLQ-STO22). Conclusions: Long-term postoperative QoL deterioration in emotional functioning, nausea/vomiting, pain, dyspnea, constipation, dysphagia, reflux, eating restrictions, dry mouth, and taste were associated with nutritional shortcomings. QoL item-level analysis, instead of scale-level analysis, may help to facilitate personalized treatment for individual QoL respondents.

Few studies have shown the correlation between metabolic syndrome and bone mineral density (BMD). The main pathogenic mechanisms of metabolic syndrome rely on chronic low-level inflammatory status and oxidative stress. There are few studies that examine the gender-specific effects of inflammation and antioxidants on BMD. In this study, we evaluated the relative contribution of these factors in patients with metabolic syndrome. We conducted a cross-sectional study of 67 men and 46 postmenopausal women with metabolic syndrome; metabolic syndrome was defined as having three or more metabolic syndrome risk factors. BMD, body fat mass, and lean body mass were evaluated. We also examined the levels of high sensitive C-reactive protein (hs-CRP), interleukin-6 (IL-6), adiponectin, vitamin E, and C in serum. Log-transformed hs-CRP levels were significantly higher in lumbar spine osteoporotic subjects than in normal subjects for women but not for men. There was no significant difference between the normal group and the osteoporotic group in other inflammatory markers. Stepwise regression analyses for BMD of the lumbar spine showed that lean body mass and vitamin E were significant determinants in men. Lean body mass and log-transformed hs-CRP were significant determinants in women Analysis for BMD of the femoral neck showed that lean body mass was a significant determinant for both men and women. There was no significant factor among the inflammatory markers or antioxidant vitamins affecting the femoral neck BMD for either gender. In conclusion, while hs-CRP is an independent predictor of the BMD of the lumbar spine in women, vitamin E showed profound effects on BMD in men but not women with metabolic syndrome.

Obesity is a significant problem affecting United States (US) firefighters. While body mass index (BMI) is widely used to diagnose obesity, its use for this occupational group has raised concerns about validity. We examined rates and types of misclassification of BMI-based obesity status compared to body fat percentage (BF%) and waist circumference (WC). Male career firefighters (N = 994) from 20 US departments completed all three body composition assessments. Mean BMI, BF%, and WC were $29kg/m^2$, 23%, and 97 cm, respectively. Approximately 33% and 15% of BF%- and WC-defined obese participants were misclassified as non-obese (false negatives) using BMI, while 8% and 9% of non-obese participants defined by BF% and WC standards were identified as obese (false positives) using BMI. When stratified by race/ethnicity, Pacific Islanders showed high rates of false positive misclassification. Precision in obesity classification would be improved by using WC along with BMI to determine firefighters' weight status.

어떤 폐쇄된 공간 내에서 운동하는 한 물체가 다른 물체와 완전 탄성 충돌이 일어날 경우 현재물리법칙에 따르면 그 공간의 질량중심 이동은 없는 것으로 정의되어 있으며 이에 따라 컴퓨터 그래픽 표현 역시 이와 마찬가지로 되어 있다. 본 논문은 폐쇄된 공간 내에서 두 물체가 충돌하는 기간동안 폐쇄된 공간의 질량중심(CM) 위치이동의 미소한 현상을 포함한 물리법칙을 정의한다. 본 논문에서 정의된 법칙은 근사적인 실험장치로 확인하였으며, 이를 이용하여 폐쇄된 공간 내에서 두 물체의 충돌 순간 형태의 그래픽 표현모델과 수식을 정의하였다. 질량중심 위치이동의 미소한 현상을 다 물체 동역학 시뮬레이션 프로그램 또는 햅틱(haptic) 프로그램에 적용하면 좀더 정확성 있는 운동을 표현할 수 있게 될 것이다. 이러한 정의는 만화영화나 그래픽으로 동작을 표현하는 곳에 적용하면 보다 현실감 있게 표현이 가능할 것이다.

Obesity was characterized in Korean elementary students using different obesity assessment tests on 103 overweight elementary students from three schools of Jeonbuk Province. The body mass index (BMI) and obesity index (OI) were compared, and the data using DEXA and CT were compared with the data using BIA and a tape measure. The results of this study are as follows: first, 27 students who were classified as obese by OI were classified as overweight by BMI, and 3 students who were classified as standard weight by BMI were classified as overweight by OI. Secondly, by DEXA and BIA measurements, there was 1.51% difference in body fat percentage (boys 1.66%, girls 1.17%) and the difference in body fat mass between boys and girls was 0.77 kg (boys 0.85 kg, girls 0.59 kg), but those differences in body fat percentage and mass were not statistically significant. Thirdly, the average total abdominal fat (TAF) measured by CT scans of obese children was more significantly related with subcutaneous fat (r = 0.983, P < 0.01) than visceral fat (r = 0.640, P < 0.01). Also, TAF were highest significant with waist circumference by a tape measure (r = 0.744, P < 0.01). In summary, as there are some differences of assessment results between two obesity test methods (BMI, OI), we need more definite standards to determine the degree of obesity. The BIA seems to be the most simple and effective way to measure body fat mass, whereas waist/hip ratio (WHR) using a tape measurer is considered to be the most effective method for assessing abdominal fat in elementary students.

A 13-year-old spayed female Beagle dog was referred with high intraocular pressure, hyperemia, and exophthalmos of the left eye and underwent ultrasound, which revealed a mass in the ciliary body of the left eye. Magnetic resonance (MR) imaging was ordered to evaluate invasion of surrounding structures and metastasis to the brain via the optic nerve. On MR imaging, a single, well-defined, smoothly marginated, triangular-to-oval-shaped mass was found. The mass was hyperintense on T1-weighted images and hypointense on T2-weighted images, similar to a previous case of ocular melanoma. The mass originated from the ciliary body and extended from the anterior chamber to the posterior chamber. Slight enhancement was observed in the mass. There was no evidence of invasion into surrounding structures or the optic nerve, and no sign of metastasis to the brain. The mass was histopathologically diagnosed as benign uveal melanocytoma.

Objectives : The purpose of this study were to evaluate the effects of oriental medical therapy on obesity and different effects according to Body Mass Index(BMI), menopause, obesity treatment experience, age, treatment period in patients. Methods : 46 patients were treated from November 2011 to April 2012 in Oriental Obesity Center, Dong-eui Medical Center. They were measured change of body compositions by bioelectrical impedance analysis every 2~3 weeks and 27 patients out of 46 were checked body compositions every 2 weeks. 46 and 27 patients were divided into two or three groups according to BMI, menopause, obesity treatment experience, age, treatment period. We compared before and after treatment body compositions. Results : Body compositions, except edema index were significantly reduced. Abdominal Visceral Fat(AVF) was significantly reduced in Obese group. Body Weight(BW), BMI, Body Fat(BF), Body Fat Percetage(BFP), Abdominal Visceral Fat Level(AVFL), Abdominal Visceral Fat(AVF), Abdominal Subcutaneous Fat(ASF) were significantly reduced in non-menopause group(43 female patients). But in 26 female patients out of 27, there were no significantly differences between groups in menopause. There were no significantly differences between groups in obesity treatment experience. But in 27 patients, BMI and AVF were significantly reduced in non-experience group and AVFL was significantly reduced in experience group. BW, BMI, BF, BFP, VAF, ASF were significantly reduced in younger age group. But in 27 patients, BW and Muscle were significantly reduced in younger age group. BMI, BF, BFP, Edema, AFVL, Abdominal Visceral Fat Area(AVFA), AVF, ASF were significantly reduced in longer treatment period group. Conclusion : The BF, BMI, BF, BFP, Muscle, AVFL, AVFA, AVF, ASF were almost decreased significantly. It resulted that the effects of oriental medical therapy in obesity was positive. And it was meaningful study to know about different effects between groups.

Purpose: The purpose of this study was to investigate the relationships between the herbal medicines used for women in puerperium on postpartum care, Kami-Saenghwatang(SHT) and Kami-Bohertang(BHT) and postpartum body composition change. We also examined the influence of gestational age, the number of parity and the route of delivery for gestational weight gain and postpartum weight loss. Methods: 239 women followed by postpartum care center. Variety factor s were conformed and then checked body composition analysis. 8 weeks later, we followed up body composition of 36 women among the former checked. and additionally asked the body weight of another 42 former checked women by telephone call. Results: $Mean{\pm}S.D$(standard deviation) of pre-pregnancy weight is $55.22{\pm}8.98kg$, $Mean{\pm}S.D$ of gestational maximun weight is $69.26{\pm}9.77kg$, $Mean{\pm}S.D$ of weight loss in postpartum 8 weeks(means sub-tract postpartum 1 week weight from postpartum 8 week weight) is $57.86{\pm}8.60kg$. The number of parities had corrrelation with gestational weight gain. Age, number of parities and route of delive were not significantly correlated with postpartum weight loss during 8 weeks after delivery, and also it was not correlated with body water mass, body fat mass, body mass index and body weight on postpartum 8 weeks whether they treated with SHT and BHT. conclusion: It was not correlated with body water mass, body fat mass, body mass index and body weight on 8 weeks postpartum whether they treated with SHT and BHT.

Objectives: To compare the body composition of the postpartal female weight-gained over the recommended during pregnancy with that of normal female with same age. female diagnosed as obesity and postpartal female weight-gained within the recommended during pregnancy. Methods: From Apr. 1. 2001 to Feb. 28. 2002, there were 745 delivery in Dept. of Obstetrics & Gynecology, Kyung-Hee Medical Center. 32 mothers of them wanted to be investigated about the weight gain during their pregnancy. We excluded 12 persons who had gained within the recommended weight$(15{\beta}{\prod})$ and had diagnosed as the diseases inducing pathologic edema, preeclamsia. gestational heart or renal diseases, for example. In 2 days after delivery(nomal) or 5 days after(Caesarean section) we analysed the body composition of 20 persons. Results: 1. Compared with normal female, body weight, body mass index and body fat of the women gained over the recommended were increased and there made alternation to the increase of the percentage of body fat or the decrease of the percentage of lean body mass. 2. Compared with obese women who had same body mass index, the women gained over the recommended showed a little increase of body fluid, protein and mineral, but had a little decrease of the percentage of body fat. 3. The percentages of body fat increased with the women gained over the recommended, the women gained within the recommended and the obese women in order. This could imply the relation between the pregnancy, weight gain during pregnancy and the obesity. 4. The weights before pregnancy were same in the women gained over the recommended and the women gained within the recommended. But the weights just after delivery kept the gap happened during pregnancy between them and its main cause was the increase of body fat. Conclusions : The women gained over the recommended during pregnancy experienced the chage of body composition and its main cause was the increase of body fat. So compared with the women gained within the recommende, postpartal obesity more frequently could happen.
