This study was conducted to find adolescent females perception of body image. The survey was carried out by self-questionnaires with 463 female school and college students in Daegu. Analysis of data was done using t-test, and ANOVA with the SAS computer program. The average height, weight and BMI of the subjects were 161.2cm, 53.4kg and 20.51kg/$m^2$. It appeared that 33.3% of the subjects were off the normal range of body weight ; in particular 25.1% of the subjects were under weight. While the subjects’perception of their own current body image was not distorted, they were dissatisfied with their body image because they wanted a very thin figure. Subjects were divided into 3 groups -underweight, normal weight, overweight-according to their current body size. Their perceptions of ideal and desired figures differed significantly between the groups, but they thought a thinner figure than normal body image as ideal and desired body image even in overweight group. As a result, dissatisfaction of body image in the overweight group was significantly larger than the normal-weight group, and that of the normal-weight group was larger than the underweight group. Percentages of weight control attempt were 51.7% and 64.7% in the normal weight and underweight subjects, respectively. Subjects were divided into 2 groups according to their weight control experience : those who have attempted, and who have not attempted. Weight control attemptees had a higher level of dissatisfaction with their body image than non-attemptees, both because weight control attemptees were fatter, and they perceived a thinner figure as an ideal and as a desired body image thin non-attemptees. From the results of this study, we confirmed that one of reasons of excessive weight control behavior among adolescent females was distorted perception about ideal body image.
Objectives This study was conducted to investigate the possibility of neurological soft signs as an endophenotype for schizophrenia by examining neurological soft signs in patients, their unaffected siblings and normal comparison subjects. Methods The study sample consisted of 32 patients, 25 of their unaffected siblings and 30 normal comparison subjects. Neurological soft signs were evaluated using the Cambridge Neurological Inventory Part 2. soft sign assessment. Results The patients were significantly more impaired than normal comparison subjects (p = 0.047) on primitive reflex. The patients were significantly more impaired than siblings (p = 0.004) and normal comparison subjects (p = 0.021) on motor coordination. The siblings performed better on sensory integration than the patients (p = 0.020) and normal comparison subjects (p = 0.036). Conclusions This study suggests that neurological soft signs might be a potential biomarker for schizophrenia, but might not be an endophenotype for schizophrenia.
The objective of this study was to examine two new parameters by which we could screen people with malignant vocal folds. The new parameters were the difference sums and Pearson correlation coefficients between adjacent pairs of intensity level matrices of narrow-band spectra. Audio files from the Korean Disordered Speech Database were analyzed by Praat, a speech analysis software, to obtain matrices of 400 intensity levels at 16 time points of each sustained vowel spectra. We limited our study to 12 normal subjects and 20 patients with malignant vocal folds who recorded at least three Korean vowels at a sound-proofed booth in Busan National University Hospital. Results indicated that the average coefficients of the abnormal subjects were much lower than those of the normal subjects while the average difference sums of the patients were much higher than those of the normal ones. Also, we found that the degree of the malignancy of the vocal folds was related to the coefficients and sums. However, some subjects at the initial stages of cancerous vocal folds yielded almost comparable coefficients and difference sums to those of the normal speakers. Further studies on larger databases will be desirable to set certain criteria or threshold levels for screening people with vocal fold diseases.

We investigated dietary effects of green tea powder (GTP) on plasma lipids, platelet aggregation, hemolysis, plasma TBARS, and liver enzymes. Thirty one volunteer diving women living on Jeju island consumed 4 g green tea powder daily for a period of four weeks and data for the study subjects were analyzed on the basis of diagnostic criteria for blood pressure (BP)(${\geq}$ 140/90 mmHg), plasma total cholesterol (TC)(${\geq}$ 200 mg/dL), and triglyceride (TG)(${\geq}$ 150mg/dL). Subjects with high BP had significantly higher TC and TG than those with normal BP. Subjects with higher TC had higher TG, and those with higher TG had lower HDL cholesterol. Platelet aggregation in the initial slope was significantly higher in subjects with normal BP, normal TC, or normal TG than their counterparts in high BP, TC, and TG. HDL cholesterol after GTP intake increased only in subject groups with normal BP, normal TC, or normal TG, and plasma TG after GTP intake decreased only in groups with higher BP, higher TG, or higher TC. Plasma TC and TG in subjects with normal BP increased after GTP intake. GTP intake caused a decrease in the initial slope of platelet aggregation in all subject groups with little effect on maximum aggregation. Total bilirubin showed a significant increase and GOT increased in all subject groups after GTP intake. Beneficial effects of short term intake of green tea powder might differ depending on the subject conditions in terms of blood pressure, plasma lipids, and other cardiovascular conditions. However, with the hypolipidemic, antithrombotic, and antioxidant actions of its bioactive flavonoids, long term usage of GTP or brewed green tea may provide preventive effects against cardiovascular disease.

To explore the relationship between weight status and food intake pattern, the Nutrition Survey results of the 2001 National Health and Nutrition Survey were analyzed. Dietary intake data of Korean adults aged 20 to 64. years who participated in the 2001 National Health and Nutrition Survey, was used along with their demographic data. Subjects were classified into 4 groups based on the BMI value of subjects: underweight, normal, overweight and obese. For male adults, obese subjects had significantly higher mean intake of energy, protein, carbohydrates, and fat than normal subjects. In addition, obese male adults consumed more animal foods, especially more meats, than normal subjects. However, females obese subjects did not show higher intake of energy or fat. Although obese male adults showed higher energy intake, calcium and iron intake per 1000 kcal was lower than normal adults. Average calcium intake in females was low; about 70% of RDA regardless of obesity level. In addition, riboflavin and Vitamin A intake was lower in overweight and obese female than in normal females. Percentage of subjects with low fruit and vegetable intake (< 400 g per day) was also high in female subjects. These results showed that food and nutrient intake patterns of obese population were different between male and female adults. These dietary intake patterns need to be considered in developing and implementing nutrition policy and intervention programs to prevent and control obesity. Moreover, the National Survey and monitoring system should be developed for continuous and effective investigation on the relationship between obesity and dietary intake.
This study was carried out to determine whether a short-tenn zinc supplementation contributes to beneficial changes in glycemic control among type 2 diabetic patients. Seventy-six diabetic subjects and 72 normal adults participated in this study. Subjects were divided into supplemented and control groups. Forty-four diabetic patients and 34 normal subjects were supplemented with 50 mg zinc daily as zinc gluconate for 4 weeks. Zinc status was assessed from fasting plasma levels and urinary excretion. The effects of zinc supplementation on fasting blood glucose, $HbA_{1c}$, insulin, and C-peptide were measured at the beginning of the study and after 4 weeks of supplementation. The changes in glycemic control indicators were compared between diabetic groups, classified by baseline $HbA_{1c}$ levels, and by diabetic duration. At baseline, the incidence of marginal zinc deficiency in the diabetic group, as determined by plasma zinc level, was approximately twice as high as in the normal adult group. The changes of $HbA_{1c}$ concentration, and fasting blood glucose following supplementation were not statistically significant in diabetic subjects. In normal subjects, a significant decrease of $HbA_{1c}$ occurred only in the zinc supplemented group. No significant changes were observed for serum insulin and C-peptide in diabetic as well as normal subjects. However, when the changes were compared by baseline $HbA_{1c}$ level, we found that diabetic subjects with $HbA_{1c}\;{\geq}\;7.5%$ showed significantly improved levels of $HbA_{1c}$ and fasting glucose after Zn supplementation. While such improvement in fasting blood glucose was significant among diabetics with shorter diabetic duration, significant levels of increase in serum insulin and C-peptide were observed in zinc supplemented subjects with longer diabetic duration. Fasting blood glucose was significantly decreased, whereas serum insulin and C-peptide were increased in diabetics with marginal zinc status. Therefore, we suggest that Zn supplementation for a short-term period may improve glycemic control in diabetic patients with higher $HbA_{1c}$ levels and marginal zinc status.
To evaluate the effect of damaged bronchial epithelium on epithelial permeability and physiologic changes of the airway in patients with bronchial asthma, we measured the concentration of protein and albumin in bronchoalveolar lavage fluid (BALF), the width of intercellular junction and bronchial hyperreactivity in 22 patients with bronchial asthma and 21 healthy subjects. The results were as follows: 1) The concentration of protein in BALF from patients with bronchial asthma was higher when compared with that of normal subjects ($237{\pm}182$ vs $113{\pm}78\;{\mu}g/mL$, p<0.05), and the concentration of albumin was also higher than that of normal subjects ($116{\pm}126$ vs $32{\pm}88\;{\mu}g/mL$, p<0.05). The ratio of the concentration of protein in BALF to that in serum was increased in patients with bronchial asthma when compared with that of normal subjects ($0.35{\pm}0.30$ vs $0.16{\pm}0.11%$, p<0.05). 2) The intercellular junction of bronchial epithelium was widened in 14 of 20 patients with bronchial asthma, in contrast, 5 of 14 normal subjects (p<0.05). The mean width of intercellular junction was greater when compared with that of normal subjects ($1.71{\pm}1.81$ vs $0.56{\pm}0.85\;{\mu}m$, p<0.05). The width was well correlated with the ratio of protein in BALF to that of serum (r=0.3226, p=0.047) when observed in 18 patients with bronchial asthma and 10 patients with normal subjects. 3) The bronchial hyperreactivity, expressed as $PC_{20}$, was inversely correlated with the concentration of protein in BALF (r=-0.3030, p=0.038) in when observed in 18 patients with bronchial asthma and 19 normal subjects. 4) The width of intercellular junction was well inversely correlated with $PC_{20}$ (r=-0.5006, p=0.002) when observed in 19 patients with bronchial asthma and 11 patients with normal subjects. In conclusion, increased permeability and the damage of bronchial epithelium may lead to change of bronchial hyperreactivity.
The purpose of this study was to investigate the relationship between obesity and, erythrocyte SOD (superoxide dismutase) activity and serum antioxidant mineral (Fe, Zn, Cu, Mn and Se) concentrations of adolescents. Subjects were assigned to one of two groups such as obese ($BMI{\geq}25$, 32 boys, 24 girls) and normal group (18.5 < BMI < 23, 27 boys, 30 girls) Subjects were evaluated based on anthropometric measurements, 24-hr dietary recalls and blood analysis. The mean age of the total subjects was 13.8 years. The mean weight (p < 0.001), BMI (p < 0.001) and body fat (p < 0.001) of obese were higher than those of normal group. There was no significant difference in nutrient intake between obese and normal groups. SOD activity of obese group was not significantly different from normal groups, in both males and females. However, in the males, serum Cu concentration of obese were significantly lower than those of normal group. In the females, Serum Mn concentration of obese were significantly lower then those of normal group. In the correlation analysis, BMI of the subjects had significantly negative correlations with serum Cu, Zn and Mn. To summarize the results, increase of obesity may lead to decrease of serum antioxidant minerals such as Cu, Zn and Mn.
The purpose of this study was to compare the anthropometry and nutrition knowledge, food behaviour and lifestyle of women college students with different obesity indexes. The subjects were 251 women college students who were randomly selected from Kunsan National University. The height, body weight, soft/lean mass, fat mass, percentage of body fat, and fat distribution were measured, and health-related lifestyle habits were evaluated based on questionnaires. The subjects were assigned to one of the following groups based on their Body Mass Index (BMI) : underweight, normal weight and overweight. The results were as follows. Their body weight, soft/lean mass, fat mass, percentage of body fat, and fat distribution were significantly higher in the overweight subjects when compared to the underweight or normal weight subjects. Standard of living, self-recognition of health status and duration of exercise were significantly correlated with their BMIs. Self-satisfaction with body weight decreased as the BMI increased. Most subjects had poor habits such as skipping meals and lack of exercises. The overweight and the underweight groups skipped meals more frequently than the normal weight group. There were no significant differences in the scores on the nutritional knowledge and the dietary behaviour of the subjects with different BMIs. Therefore, proper nutritional education on regular meals and intervention are required if women college students are to have normal weights and healthy lifestyles.
