This study examined the physical and mental health factors affecting the industrial accidents of 142 injured and 1,212 uninjured workers in the shipbuilding industry from 1986 to 1988. The results acquired from the Todai Health Index (THI) and from analysis of the health examination were as follows: 1. Among the personal characteristics of the workers, the educational level of injured workers was significantly lower than that of the uninjured workers. 2. Among the physical characteristics, vision and $R\ddot{o}hrer$ Index of the injured workers were lower than those of the uninjured workers, and the difference was statistically significant. On the other hand, the differences in height, weight, hearing function, hematocrit, blood pressure, urine test, and X-ray findings were not statistically significant between the injured and uninjured workers. 3. The score of the THI questionnaire on the physical and mental health of the injured workers was higher than that of the uninjured workers, and the difference was statistically significant. 4. Form the THI score, the industrial workers had complained more about mental health than physical health and there was a statistically singinficant relation with the industrial accidents. 5. The relative risk expressed in terms of the odds ratio was 2.9 for poorer vision, 2.7 for a lower educational level, 2.2 for a higher THI score and 1.6 for overdrinking. 6 Educational level, vision, and the THI score were selected as significant factors influencing industrial accidents based on a log-linear model. According to the results of this model by logistic analysis, the odds ratio of industrial accidents was 1.8 for a lower educational level, 1.7 for poorer vision, and 1.6 for a higher THI score. 7 By event history analysis with the dependent variable as the duration of work at the time of the industrial accident, educational level, age, $R\ddot{o}hrer$ Index and THI score were the statistically significant variables selected, and the hazard rate of industrial accident occurrence was 0.24 for a lower educational level, 0.92 for age, 0.99 for a lower $R\ddot{o}hrer$ Index and 2.72 for a higher THI score. As we have seen, educational level and THI score were the most significant factors affecting the hazard rate of industrial accidents. Vision, $R\ddot{o}hrer$ Index, age, and drinking behavior were also statistically significant variables influencing industrial accidents. Therefore, in order to prevent industrial accidents, it is necessary to establish a health management plan for industry which can objectively evaluate not only the physical but also the mental health of the workers. If we use this type of study as a prospective study design, we can determine the relative risk of physical and mental health factors on industrial accidents. Furthermore, it is expected that this type of study will provide workers at high risk with more precise basic data for a health managment plan for industrial accident prevention.

Supposing that somatotype evaluation results would have significant differences between the public group with less amounts of exercises and the special group with intensive exercises for three to four times a day, this study aimed at comparing the mutual consistency between the results determined by somatotype evaluation tools such as visually calculated index(VCI), R$\ddot{o}$hrer's Index(RI) and Body Mass Index(BMI). The public, taekwondo players and judo players groups were composed of fifty persons, taekwondo players and judo players passed through VCI determination, respectively. Their height and weight were examined and analyzed with somatotype evaluation tools. Comparison of somatotype dispersion of RI and VCI showed that most women were determined by VCI as lean type but were determined by RI as normal type. And that women were determined by VCI as fat type but were determined by RI as normal type. Therefore both men and women showed significant differences in VCI and RI. Comparison of somatotype dispersion of VCI and BMI showed that both men and women were overestimated or underestimated by VCI rather than by BMI. Comparison of somatotype dispersion of RI and BMI showed that men were less determined by BMI as lean type compared with women; both men and women less determined by BMI rather than by RI as normal type; and both men and women, in particular, were more determined by BMI as fat type but men were more determined by BMI rather than by RI as fat type. Total somatotype consistency by tools showed that VCI has the greatest possibility of determining the public group, compared with other groups as lean type and that the consistency of the three tools were relatively higher for the taekwondo players and judo players groups, compared with the public.

The purpose of this study was to provide information on obesity assessment for Koreans. Among total of 1012 research papers enlisted in the Korean J Community Nutrition form 1996 to 2011, 248 articles were examined in which subjects were divided into more than 2 groups by obesity rate. About the method of anthropometric data collection, more than half of the research papers examined 52.5% and 28.7% of studies utilized the directly measured data and self-described data, respectively. About the utilization of obesity assessment methods, indirect methods of weight-height index (BMI, BMI percentile, and R$\ddot{o}$hrer index) and PIBW (WLR, Broca index, and KDA) were 62.4% and 23.2%, respectably, and the direct method of percent body fat assessment was only 9.3%. The most frequently utilized methods were WLR in under primary and primary school children, and BMI in the middle and high school students and in adults. For primary school students, WLR was the most frequently utilized method up to 2007, but it changed to BMI percentile afterward. Broca Index was no longer utilized since 2008. There were no articles utilizing BMI percentile and R$\ddot{o}$hrer index for obesity assessment in adults. Criteria for obesity assessment were not consistent among research papers: for example, % body fat, 19~40%; BMI, 20~30; BMI percentile, 85th or 95th. In the case of PIBW, 120% of ideal weight was the most frequently utilized criterion for obesity. Based on these findings, we suggest that proper methods and criteria of obesity assessment for each age group should be determined and proclaimed.

As a preliminary research of body characteristics analysis of Korean obese woman, this study aims to select optimal obesity judgment tools for reliable sampling of obese subjects from 2,425 female measurement data out of 2004 Size Korea project's raw data. From previous researches related to obesity, 7 obesity judgment tools were chosen. 2007 obesity rate(26.3%) of Korean female adults was refered in selecting optimal obesity judgment criteria in the study. The results are as follows. Firstly, it was verified that BMI was the most suitable in judging and sampling the obese subjects by the percentile analysis. R$\ddot{o}$hrer index was also reliable in grouping the obese subjects from a population. Secondly, it was concluded that the obesity ratios of relative weight 120 and higher group, R$\ddot{o}$hrer index 1.6 and higher group and waist girth 80cm and higher group were the most similar to obesity rate of Korean female adults by 2007 National Health & Nutrition Survey. Thirdly, 30 direct measurements, age, 2 drop values and 6 ratios of 7 groups by the obesity judgment tools showed the significance each other at p<0.001 level. On the other hand, "bust point to bust point" and "waist to hip length" measurements didn't show the significant differences among 7 groups. Conclusively, 4 to 5 satisfactions out of 7 obesity judgment criteria were adequate and sufficient in sampling the obese subjects. If it is needed the strict criteria for judging the obesity, 5 satisfactions and higher group will be the best choice as the obese subjects. However 4 satisfactions and higher group generally, will be adequate for sampling of the obese subjects.

The purpose of this study was to evaluate the effect of a weight control program on anthropometric values, serum lipid profiles and nutrient intakes. The subjects of this study were 38 obese children (boy : 17, girl : 21) with obesity index over 120%. The weight control program for obese children included nutritional education (50 min) and exercise (50 min) for 10 weeks. The nutrition intakes of the children were surveyed before and after the weight control program by 24hr recall test. The BMI, R$\ddot{o}$hrer Index, Obesity Index, WHR (Waist - Hip ratio) and body fat(%) were significantly decreased after completion of the weight control program. The total cholesterol and HDL-cholesterol of subjects were significantly increased after the weight control program. Distribution of serum lipid profiles was slightly changed. The energy intakes were significantly decreased (p < 0.001). from 1760.8 kcal to 1435.2 kcal. In addition, the intakes of P, Zn, retinol, vitamin $B_1$, vitamin $B_2$, vitamin E and niacin were significantly decreased. while intakes of vitamin C and folate were increased. Calcium and folic acid were upper 25% of subjects, under EAR(Estimated Average Requirements) intake before the weight control program. The distribution of energy intakes was significantly changed into positive status; fat percentage was decreased 26.3% to 22.1% (p < 0.01). Carbohydrate was increased 58.6% to 61.2% (p < 0.05). Meal distribution of energy intakes was changed; calorie percentage from lunch significantly increased from 32.2% to 38.3%. Calorie percentage from snack significantly decreased from 17.7% to 13.5%. In conclusion, weight control program for 10 weeks is effective in obesity index and nutrient intakes although serum lipid values were a little changed.
