Objectives: This study was conducted to compare health behavior between obese children and those with standard body weight, analyzing the correlation in their health behavior, and further making it useful data for the development of programs for a better education on health. Methods: To achieve the goal of this survey as mentioned, we have carried out a research targeting on a total of 636 elementary school students, 505 children of standard body weight and 131 children of obesity, all of whom belong to elementary school students in Seoul, the capital city of Korea. And we have itemized the research into 'eating habits', 'physical activity, 'dieting experience in the past', and 'stress and release management' in order to spot the specific health behavior leading to obesity. Results: 1. Factors for diseases mainly from obesity were statistically significantly differentdepending on degree of the subjects' self-respect and a history of obesity in their families, father($x^2$=7.172, p=.007), mother($x^2$=9.011, p=.003), and siblings($x^2$=12.431, p=.000). 2. Regarding the subjects' eating habits, some items were statistically significantly different: taking algae($x^2$=3.324, p=.043), eating breakfast($x^2$=6.070, p=.010), and eating fast($x^2$=8.551, p=.002). 3. There were some statistically significant differences in the subjects' dieting experience. For the latest 1 year, they made some attempts for that: fasting($x^2$=4.229, p=.040), reduction of eating($x^2$=25.377, p=.000), eating one meal a day($x^2$=5.582, p=.018) 4. OR(Odd Ratio)of Percieued obesity was 0.15 in the subjects' under weight than normal weight. And there was OR(Odd Ratio) 11.72 in the subjects' over weight. We can witness obese children think that they are over weight(p=.000).

In a TV component manufacturing factory, 102 male workers aged $20{\sim}39$ years old were participated in testing for physical fitness. At the same time, worker's periodic health examination was done. Test battery for physical fitness include grip strength, trunk flexion, standing long jump, side step, single leg balance with eye close, push ups and Harvard step test. As a result of testing for physical fitness, synthetically, there is no difference between manufacturing workers and officers. By bioelectrical impedance test, it means a declining tendency to all 7 factors in the obese workers, and so, it is important for obese workers not only to promote physical fitness but also to promote health. Excluding grip strength and single leg balance with eye close, 5 fitness factors are negatively associated with degree of diastolic Blood pressure, but it is statistically not significant. And levels of sGOT & sGPT have no association with physical fitness factors.

Ascertainment of accurate pharmacokinetic parameters for aminoglycoside dosing remains critical, as the serum drug concentration relates directly to both the therapeutic response and toxic effect. In the initial dosing of aminoglycosides, the volume of distribution is especially important because the dosage is calculated by multiplying the volume of distribution by the desired serum concentration. Aminoglycosides distribute into mainly the extracellular fluid and it has been reported that the volume of distribution is 0.25 L/kg. Penetration of polar aminoglycosides into adipose tissue occurs to some extent, but varies according to the degree of obesity. Therefore, dosages may be overestimated or underestimated according to the type of the dosing weight in overweight or underweight patients. Prior investigations have suggested various dosing weights which are multiplied by the popular volume of distribution to calculate the total volume of distribution. Based on other investigations, we calculated a new dosing weight which was applicable to all patients regardless of obesity in order to use the popular volume of distribution. We estimated IBW+$0.414^{\ast}$(TBW-IBW) as a new dosing weight with the SAS program. A new dosing weight is similar to those of other studies which examined in morbidly obese patients. Consequently we suggests that the dosing weight reported in morbidly obese patients can be extended to a broader patients population. But we found that the volume of distribution per kilogram from our patients was significantly larger than that for foreign patients(0.343L/kg vs 0.25 L/kg)(Kor. J. Clin. Pharm. 1999; 9(1): 15-18)

The purpose of the present study was to investigate the relationship between obesity and dental caries in children and adolescents. This study was analyzed by searching the following words in Google Scholar (https://scholar.google.co.kr), Kiss (kiss.kstudy.com), KCI (www.kci.go.kr), and RISS (riss.kr): "pediatric," "juvenile," "obesity," and "dental caries." A total of 19 Korean and 10 foreign studies out of 107 studies were selected after excluding the studies based on the exclusion criteria. When evaluating the relationship between childhood and adolescent obesity and dental caries, 16 out of 29 articles (55.2%) indicated a significant relationship, and 2 (6.9%) indicated different results based on sex, while 13 articles (44.8%) showed no significant relationship between obesity and dental caries. Among the significant studies, a total of 10 (34.5%) showed that the number of dental caries increased according to an increase in obesity, i.e., from normal to overweight to obese. A total of 5 studies (17.2%) reported that the number of dental caries increased in underweight individuals compared to those of normal weight, or decreased according to an increase in obesity, while 1 study (3.4%) indicated that the number of dental caries increased in both the underweight and obese groups compared to the normal weight group. Therefore, studies on the relationship between dental caries and the degree of obesity in children and adolescents have not shown a certain trend.

The purpose of this study was to investigate the association between daily beverage intake and obesity in young adults. This cross-sectional study was conducted with 256 adults in their 20s and 30s. Obesity was evaluated by anthropometric measurement of body mass index (BMI), waist to hip ratio and waist to height ratio. In addition, the daily intake of milk, caffeinated beverages, sweetened beverages, and alcoholic beverages was investigated using the dietary record and 24-h recall methods. Based on the BMI, men and women were classified into underweight, normal, overweight and obese. Among men, 38.3% were found to be normal, 28.1% were overweight and 31.3% obese. Among women, 11.7% were underweight, 73.4% were normal, and 10.2% were overweight, which was significantly different from men. In women, the BMI of the milk consumers was significantly lower than the non-consumers. Also, the obesity indices of caffeinated beverage consumers were significantly lower than the non-consumers. An analysis of the correlation between beverage intake and the obesity index showed that the intake of caffeinated beverages among women had a significant negative correlation with the obesity index, and intake of alcoholic beverages had a significant positive correlation with waist to height ratio. This study suggests that intake of milk and caffeinated beverage may have a positive effect on obesity, whereas the intake of alcoholic beverages may have a negative effect, especially in young adult women.

Increasing fat tissue of obese people, increases the rate of cardiovascular disease, diabetes, metabolic syndromes and dyslipidemia. An increase in the focal tissue of pancreas is a known risk factor of these diseases. Although there exists sufficient research on the diagnosis and treatment of pancreatic cancer, studies have been done on fatty pancreas. In this study, based on ultrasound imaging and using a texture characteristic of GLCM, fatty pancreas was divided into three categories: mild, moderate and severe. We compared and analyzed the three groups was by Pancreatic ultrasonography and body characteristics, serological tests, pressure and the degree of arteriosclerosis, against normal control group. The following parameters of control and test groups were measured: WC (waist circumference),BMI (body mass index), TC (total cholesterol), TG (triglyceride), HDL-C (High-density lipoprotein cholesterol) and LDL-C (Low-density lipoprotein cholesterol), SBP (systolic blood pressure), BST (Blood Sugar Test) and aortic PWV (pulse wave velocity). We observed the values correspondingly increasing fat deposition. However, ABI (Ankle Brachial pressure index) stenosis and HDL-C levels decreased with increasing fat deposit (p <0.05); a drop in these parameters are known to be harmful to the human body. The difference in texture characteristics between normal control group and pancreatic fatty group (mild, moderate, and severe) was statistically confirmed. Ultrasound imaging of pancreatic steatosis categorized the disease as mild, moderate and severe based on the characteristic texture. In conclusion, we observed on increase in metabolic syndrome, dyslipidemia, and arteriosclerosis, proportional to the degree of pancreatic fat deposition. The escalation of these diseases was confirmed and was directly related with predictors of cardiovascular diseases.

R$\ddot{o}$hrer index, Vervaeck index and Body Mass Index(BMI) are frequently used in order to judge obese subjects in clothing & textiles field. However, there are no certain criteria of judging the degree of obesity. Each researcher utilized these obesity indices according to their own criteria so far. Therefore, the purpose of the study is to suggest a reliable obesity index and new criteria for judging the degree of obesity. The results are as follows; Utilizing frequency analysis, main percentiles, minimums, maximums and ranges were presented by 5 age groups from twenties to sixties. Obesity rates dramatically increased, the subject got older. Especially, obesity rate of the subjects in their fifties and sixties were much higher than other age groups. 1.6 & higher can be used in the R$\ddot{o}$hrer index, 98 & higher can be used in the Vervaeck index, and 25 & higher can be used in the BMI as the Optimal criteria of the obesity. Total of 24 body measurements and 3 obesity indices were used for analyzing the correlation analysis. All heights measurements showed negative correlation with the 3 obesity indices. It is determined heights measurements have high correlation with R$\ddot{o}$hrer index compare to other indices. Crotch height, interscye back, neck shoulder point to breast point, bust circumference, waist circumference, upper arm circumference and armscye circumference have high positive correlation with all obesity indices. According to the ANOVAs by each percentile group of the R$\ddot{o}$hrer and Vervaeck indices, there are big significances in all measurements and obesity indices except arm length. In general, heights decreased significantly by getting bigger, while circumferences and lengths, widths and indices increased rapidly by getting bigger. The results of the analysis by each percentile group in the BMI, it showed the significant differences in the all measurements except cervical height and arm length. There were similar tendency of differences according to the degree of the obesity in BMI percentile groups. It was confirmed that the BMI is the most reliable index for judging the obesity owing to the high correlations and significant differences with other measurements.

This study was purposed to present the basic data on the elderly women's somatotype to develop new briefs design with high body-adaptability. The subjects were 115 elderly women in the 60s and 70s and the factor analysis for 32 directly measured values of the body parts was carried out to sort out the constituent factors of the elderly women's bodies, and finally 4 factors were decided. The first factor was the thickness of the trunk and the degree of the obesity in the center of the width, thickness and circumference. The second factor is the perpendicular size of the body with high loads on the longitudinal direction of the body. The third factor was the leg shape. The last factor was the degree of the sagging hip. The elderly women's somatotype was classified into 3 types. The first type was the 'mean somatotype' with the biggest height and the longest lower half body of the three types. The second type was the 'obese somatotype' with the mean height and length of the lower body and with the largest circumference and width. The last type was the 'skinny somatotype' with the smallest values of all the items in the perpendicular size and the degree of the obesity.

Purpose : The purpose of this study was to investigated the dietary habits of students in order to identify risk groups according to their Body Mass Index (BMI), and to compare the eating behavior of students in the normal range (19${\le}$24) and those in risk groups (BMI${\le}$19, 24${\le}$27, BMI>27). Method : 1176 elementary school students, 850 middle school students and 672 high school students in Wonju City, were the participants The instrument for this study was a structured questionnaire that included demographic data as well as dietary habits, and the eating behavior instrument developed by Stunkard & Messick(1985) and revised by Kim & Kim (1997). Result : 1) As students moved up ingrade level their dietary habits became more irregular and the degree that students chewed food was reduced 2) As students moved up in grade level, a greater number of the student did not eat breakfast. The reasons given were that there were not enough time before classes started(40.4%) and a lack of appetite in the morning(10.6%) in high school students. 3) As for supper, from 67.8 to 81.9% of subjects reported having regular supper. However the rest of the subjects did not eat supper because of anorexia and fear of weight gain. 4) The results identified risk groups according to their BMI showed that for elementary school students, 55.9% were in the low weight group, 5.5% in the overweight group, and 0.9% in the obese group. For middle and high school students, 40.6% and 35.5% respectively were in the low weight group, 7.4% and 6.3% in the overweight group, and 4.1% and 2.5% the obese group. 5) Comparisons of the eating behavior of students in the normal weight group with that of those in the three risk groups showed that there significant differences in 'hunger' and cognitive restraint of eating' in elementary school students, and significant differences in 'cognitive restraint of eating' in middle and high school students. Conclusion : The results of this study show that management of diet in school health should be addressed from both the aspect of lack of nutrition and that of excess nutrition. In other words, good diet is as important for students in the low weight group as it is for those in the overweight and obese groups. The establishment of good dietary habits and eating behavior in students, by nurses and dieticians should be done by providing repeated diet education and involvement in diet counseling.

This study was carried out to identify the relationship of biochemical bone turnover markers, bone mineral density (BMD), and general characteristics in Korean women. One hundred eighty healthy women, 20 to 50 years of age, living in Gwangju and Chonnam participated. Serum bone-specific alkaline phosphatase (BAP) and osteocalcin (OC) were used as bone formation markers and N-telopeptide of type 1 collagen (NTx) was used as a bone resorption maker to evaluate the state of bone turnover. T-scores were measured to evaluate BMD. We analyzed general characteristics, including age, menopause status, osteoporosis history, alcohol consumption, physical activity level, and degree of obesity (BMI, percent of fat). The BAP level significantly decreased in the group of twenty-year olds and increased in the non-alcohol consuming group, the group with a family history of osteoporosis, the menopause group, and the obese group (p<0.05). The OC level was lower in the group of twenty-year olds and increased in the non-alcohol intake group and the menopause group (p<0.05). BMD significantly decreased in the obese group (p<0.05). In conclusion, BAP and OC were affected by age, alcohol consumption, osteoporosis history, menopause status, and obesity. BMD was affected by obesity degree. These results suggest that the management of alcohol consumption and obesity are important for maintaining bone status during aging in Korean women.
