  • Background: Sitting posture may be related to risk factors, including inadequate weight-bearing support, particularly when maintained for long periods. Considering that body weight is loaded in a closed support system composed of the seat, backrest, floor and working surface, the aims of the present study were to describe the development of an ergonomic sitting workstation to continuously record weight-bearing at the seat, chair, backrest, work surface, and floor and to test its measurement properties: reproducibility, criterion-related validity, and sensitivity. Methods: Rigid bodies (1 to 30 kg) and participant weights were recorded to evaluate the workstation measurement properties. Results: Rigid body tests showed variation values less than 0.050 kg on reproducibility test and errors below 5% of measured value on criterion validity tests. Participant tests showed no statistically significant differences between repeated measures ($p{\geq}0.40$), errors were less than 2% of participant weights an sensitivity presented statistically significant changes (p = 0.007). Conclusion: The sitting workstation proposed showed to be reliable, valid and sensitive for use in future ergonomic studies to evaluate the sitting posture.

  • Clothes and human body are inseparably related. Aesthetic consciousness of the body determines the form of clothing, reflecting the time and culture as well as the individual and society. Clothes can even reorganize the meaning of the body, while transcending their instrumental functions of protecting, expanding and deforming the body. Using 'body' to analyze the clothing form, my study develops a framework by which to classify the planarization of the body in Japanese avant-garde fashion. In order to inquire the formative style and aesthetic values expressed in Japanese avant-garde fashion, my study examines subjects from the discourse on the body to the fashion collections of the 20th and 21st century. The results of the study are as follows. Japanese avant-garde fashion focuses on a planarization of the body which questions the three dimensional construction of the body in more conventional clothing system. Un-structured, variable space posited between the body and clothes, participation of the wearer, attention to recent technology and material, and absence of gender identification characterizes the planarization of the body in Japanese avant-garde fashion. The absence of body in fashion stresses a will-to-form rather than mere bodily proportion and structure, which explores trans-extensity that goes beyond the boundary of the body Ultimately, planarization of the body betrays the correspondence between signifiant and signifie in sartorial convention. Aesthetic ideal of the body is visualized in the form of a dress. Some clothes prioritize the body, particularly the feminine bodily curves, while others focus on the clothing itself as abstract and sculptural forms. Fashion continues to explore forms and images that transcend the traditional representations of the clothed body. As a type of intimate architecture, fashion always mediates the dialogue between clothes and body, or fashion and figure. My study suggests a framework to analyze bodily representation in Japanese avant-garde fashion, focusing on the relationship between the clothes and body.

  • The purpose of this study was to determine the probability of overweight throughout childhood in relation to the presence of overweight at birch or in early childhood, and presence of overweight in children's parents. Weight and height measures were collected at birth and at ages of 7, 10, 12 years from 655 6th grade primary schoolchildren. Childhood overweight was defined as a body mass index at or above the 85th percentile for age and sex, and overweight in children's parents as a body mass index at or above 27. The prevalence of overweight increased with age of the children. Overweight at birth was not associated with overweight at 12 years of ages. However, overweight at 12 years old was already related to overweight at 7 years old. In comparison to non-overweight peers, overweight children at ages 7(OR = 7.64, 95% CI = 4.32-13.51) and 10 years(OR = 19.69, 95% CI = 11.42-33.94) had a higher rick of becoming overweight at 12 years of age. Among children who was overweight at age 7years, 60.7% remained overweight 5 years later, Yearly increment in BMI of overweight children was larger than that of non-obese children (1.15-1.65kg/m$^2$vs 0.50-0.71kg/m$^2$. As compared with the lower case in mealy increment of BMI, the probability of being overweight at age of 12 years was greater in higher case. BMI values at age 7years were positively correlated with BMI values at age of 10 and 127ear,i, and with annual increments in BMI. But those relationships with birth weight were not observed. Children were at greater risk for overweight if at least ogle parent was overweight. The odds ratio for child overweight associated with maternal overweight was 2.41(95% CI = 1,13-5.IS), and those associated with paternal overweight 1.70(95% CI = 0.92-3.17). And parents' BMIs were positively correlated with children's BMI values and yearly BMI increment. In conclusion, overweight at early childhood and annual inclement in BMI can be important in predicting the prevalence of overweight and the risk that overweight will remain after 7 years of age. The risk of being overweight throughout the childhood increases by the parents'overweight.

  • Recently, recombinant human erythropoietin (rHu-EPO) has been used to treat various types of anemia. YHB216 is a new rHu-EPO developed by Yuhan Research Institute. In this study, we investigated the single dose and 4-week repeated dose toxicity of YHB216 in Beagle dogs. In the single dose toxicity study, YHB216 was administered intravenously at single dose levels of 0 and 25,000 IU/kg to dogs (2 dogs/sex/group). There were no treament-related changes in survivals, clinical signs, body weight gain, hematological values, blood chemical values, and necropsy finding during experimental period. In the repeated dose toxicity study, YHB216 was administered intravenously to dogs for 4 weeks at the dose levels of 0, 100, 500, and 2,500IU/kg (3 dogs/sex/group). There were no toxicologically significant changes in clinical signs, body weights, food and water consumptions, ophthalmoscopy, urinalysis and blood chemistry. There were increased values of red blood cell, hemoglobin, and hematocrit at all treated groups. Spleen revealed increased weight and extramedullary hematopoiesis at 500 IU/kg or more. These changes are all considered to be Pharmacology-related effects and were recovered after 4-week recovery period. From these results, it is concluded that LD50 value was above 25,000 IU/kg in the single dose toxicity study of YHB216 in dogs and the no observed adverse effect level (NOAEL) was 100 IU/kg day in the repeated dose toxicity study of YHB216 in dogs.

  • The present experiment was performed to study whether or not ovariectomized female rats can be used as an animal model to investigate the effects of estrogen on body compositions. Six-month-old, female rats were ovariectomized and the changes in body compositions were evaluated 6 months after surgery. As summarized in Fig. 2, body fat accretion was double in ovariectomized rats compared to shamoperated rats. Muscle weights were not d!fferent, while bone weights were lower in ovx rats than in sham rats when the values were expressed as a per\ulcornercentage of body weight. Results of the present study suggest that these ovariectomized rats can be utilized as an animal model to study the body compositions of postmenopausal obese women and related health problems.

Using 'body' to analyze the clothing form, my study develops a framework by which to classify the representation of the body in fashion focusing on the representation of physicality. In order to inquire the formative style and aesthetic values expressed in representing body in fashion, my study examines subjects from the 14th century European costumes to fashion collections of the 20th century. In fashion, representation of the body is visually analogous to the ideal boily shape and structure, including a realistic presentation of the body as well as reflection of aesthetic ideals. Manipulation of physicality entails the reconstruction of the ideal body image through the clothes that modify physicality into unnatural body. Ruff collar, gigot sleeve, crinoline, bustle, stomacher, and corset were all used to materialize the fictitious curves symbolizing femininity, authority, healthiness, maternity, virginity, socioeconomic status, and fertility. Accentuating specific clothing parts represents emphasizing the symbolism of the correspondent body parts. Consequently, in this phase signifiant is $signifi\'{e}$. Aesthetic ideal of the body is visualized in the firm of a dress. Fashion continues to explore forms and images that transcend the traditional representations of the clothed body. As a type of intimate architecture, fashion always mediates the dialogue between clothes and body, or fashion and figure. My study suggests a framework to analyze bodily representation in fashion, focusing on the relationship between the clothes and body.

  • A mutation in the promoter region of uncoupling protein 3 (UCF3), specifically the -55C longrightarrow T transition, may influence an individual's energy metabolism and body weight. The objective of this study was to investigate the effect of a weight reduction program on endocrine functions and body fat distribution, related to UCP3 promoter genotype. Ninety overweight pre-menopausal female subjects participated in the weight reduction program at Yonsei University Hospital, and were placed on a calorie-restricted diet (300 kcal less than their daily requirements) for 12 weeks. After 12 weeks, all subjects on the program lost approximately 5% of their initial body weights and had lower Body Mass Index (BMI) values. Among the 90 women, 56 had a normal (without mutation) UCP3 genotype, while 34 women had mutations in the promoter region of UCP3. Despite similar weight reductions in both groups, a significantly higher decrease in abdominal adipose tissue was observed in the normal UCP3 genotype group, compared to the group with mutations. In particular, there was a significant reduction of fat at the lumbar 1 (Ll) level in the without-mutation group. Serum levels of total cholesterol, apolipoprotein Al were significantly decreased in the without-mutation group, by 4.4% and 5.7% respectively. Serum levels of hormones were not significantly changed in both groups artier the intervention. However, in the group without the mutations, the leptin level significantly reduced by 23.4% (p<0.001). Serum free fatty acid (FFA) concentration was significantly increased in the group with mutation following the weight reduction program. On the other hand, FFA responses were shown similar increases in both groups. In conclusion, although no difference was found in the magnitude of weight reduction in both groups, there were significant differences in body fat distribution and in endocrine function between the groups.

  • The purpose of this study was to evaluate the nutritional status and to identify related factors in elderly hemodialysis patients. Sixty-four patients who were registered in Asan Medical Center, Seoul, Korea, participated in the study. The data was collected between September and December, 2003. General characteristics were obtained with the use of an interviewer-administered questionnaire. Anthropometric and biochemical data, 3-day dietary records and dietary habits were also obtained. The results of this study were analyzed with t-test or $X^2$-test using SPSS package program. The percentage of elderly hemodialysis patients who were undergoing mild to severe malnutrition (MN group) and were normal nutrition (NN group) by subjective global assessment (SGA) criteria were 46.9% and 53.1 %, respectively. Appetite (p < 0.05) and dietary cholesterol intakes (p < 0.05) were significantly lower in MN group than the NN group. Body mass index (BMI, p < 0.001), lean body mass (LBM, p < 0.05), triceps skinfold thickness (TSF, p < 0.01), mid ann circumference (MAC, p < 0.01) and mid ann muscle circumference (MAMC, p < 0.05) were also lower in the MN group than the NN group. There were also significant differences in blood urea nitrogen (BUN, p < 0.05), creatinine (p < 0.05), prealbumin (p < 0.001) and C-reactive protein (CRP, p < 0.05). SGA was negatively correlated with serum BUN, creatinine and pre albumin, dry weight, BMI, LBM, total body water, TSF, MAC and MAMC, and positively correlated with age. In stepwise multiple regression analysis, SGA was related to BMI, CRP, age and BUN. In conclusion, almost half of the subjects were in malnourished status and had lower values in anthropometric and biochemical data. Our results suggest that SGA is a simple and adequate method for assessing the nutritional status in elderly hemodialysis patients and adequate dietary guidelines based on individual nutritional status are needed in the patients.
