The purpose of this study was to evaluate the usefulness of BMI application to Urography CT by applying different tube voltages in accordance with body mass index. Group A (n = 38) with body mass index of lower than 25 was examined with tube voltage of 100 kVp while Group B (n = 45) with a BMI of 25 and higher was examined with tube voltage of 120 kVp. C group (n = 37) with body mass index (BMI) of lower than 25 was examined with tube voltage of 120kVp. Although the difference in average dose between group A (100 kVp) and group C (120 kVp) with low body mass index (BMI) of lower than 25 was $214.8mGy{\cdot}cm$, there was no significant difference in qualitative evaluation and, compared with patient group with body mass index of 25 and higher, results obtained were rather good. Therefore, this study verified that the tube voltage of lower than 100 kVp does not have adverse effect on the quality of image for patients with body mass index (BMI) of lower than 25.

This study examined BMI distributions among older adults in three different countries: the U.S., Japan, and Korea. The paper also explored differences in the factors predicting BMI in the three countries using three data sets: the U.S. Longitudinal Study of Aging (LSOA II, 8,589 persons), the Nihon University Japanese Longitudinal Study of Aging (NUJLSOA, 2,888 persons), and the Korean Longitudinal Study of Ageing (KLoSA, 2,397 persons). Descriptive analysis and multiple regression were performed. Japanese older adults were somewhat lighter than Koreans with fewer people at the upper end of the BMI distribution. Distributions of BMI among both Koreans and Japanese are shifted leftward relative to Americans. There is less dispersion in the distribution of BMI for Koreans and Japanese than among Americans. The association between socioeconomic variables and BMI is stronger in the U.S. and Japan than in Korea. Demographic variables are strong predictors of BMI in Korea. In Japan, all health behaviors have significant effects on BMI. It is concluded that the relationships between behavioral, demographical, and socioeconomic factors and BMI are not the same across countries. Results have policy implications for the involvement of health practitioners in helping older adults to control weight.

A descriptive research is studied to identify the physical factors affecting to cognitive function among elderly residents over 65 years old in a community. The data were collected from 352 participants as part of a health-related survey by home visits in Seoul in 2010-2012. Their cognitive function was measured using the Korean form of Hasegawa Dementia Scale(HDS-K) and the collected data were analyzed by using t-test, ANOVA, and multiple regression analysis. From the analysis, the prevalence rate of cognitive impairment was 13.6%. Elderly residents in a community showed different cognition levels by the status of age, change of weight, change of BMI, walking and flexibility exercise. Especially, the lowest cognition level was found in the normal BMI group with decreased BMI change by over 3. The factors influencing on cognition level of the elderly with normal BMI were age, change of weight, change of BMI, and walking exercise. The variance indicated 12.2% as their cognition level. Therefore, for preventing the cognitive impairment of the elderly that were rapidly decreased of BMI, we need the program to manage their nutrition and walking exercise.

Improved quality of life has increased in a population with a high BMI (Body Mass Index). Accordingly, the development of a system for prevention of obesity management is required. Because a requirement for the prevention of obesity management system. This system has been developed to solve this problem and it is done by measuring the user information of the individual's body. The purpose of this paper is to understand the changes in your own BMI over the course of usage of this application and store the BMI in the database. This BMI data is expressed as a graph to the user and based on the BMI graph, the user is suggested to the type of exercise required by his body. The most appropriate exercise equipment's are shown to the user based on the BMI and also recommendations based on the historical data of other users with similar BMI. This system also recommends chronic diseases depending on blood sugar, blood pressure.

Purpose: To investigate self-esteem according to differences between real and ideal Body Mass Index (BMI) in female college students. Methods: Subjects were 587 female students in Korea. Data was collected by using a developed questionnaire through pretesting. Results: Actual number (46.7%) and actual number (5.1%) of participants were defined as being underweight and overweight, respectively. Nearly all participants expression high dissatisfaction with their body shape. Averages of 1.02, 2.97, 7.81 were revealed for underweight, normal weight and overweight group differences between real and ideal BMI. Those who were defined as overweight exhibited significantly self-esteem than those who were defined as underweight. Conclusions: The belief that body shape is heavier than actually the case may be prevalent among female college students in Korea. This difference between the real and ideal BMI negatively influences self-esteem. Programs aimed at improving body image awareness an self-esteem among female college students are needed.

The objective of this study was to examine measuring agreement between middle phalanx of the third finger and cervical vertebrae analysis for assessing skeletal maturity according to body mass index percentile. A retrospective chart view was used to select patients with body mass index data, hand - wrist radiographs and lateral cephalograms of same day. The patients were divided into 4 groups by body mass index percentile. The hand - wrist radiographs were analyzed using modified middle phalanx of the third finger method and the lateral cephalograms were categorized according to cervical vertebral maturation stage. The degree of agreement between the 2 methods of analyzing skeletal maturation was measured by calculating weighted kappa statistic according to body mass index percentile group. There was a good agreement between the 2 methods in the entire body mass index percentile group. According to the body mass index percentile group, the agreement was found to be different, and the pattern was different between boys and girls. Pediatric dentist should consider sex and weight status when evaluating growing children and adolescents because it can affect the agreement of 2 method of analyzing skeletal maturation.

The purpose of this study is to find a classification method with high accuracy in regard with sasang constitutional diagnosis. The BMI, blood pressure, pulse wave, and Sasang constitution diagnosed by a specialist was collected from 2848 subjects who were apparently healthy. Through a selective procedure, the data of 1635 subjects was used in the analysis. The results with the classification methods such as the discriminant analysis, regression, decision tree and neural network were compared with the diagnosis of a Sasang constitutional specialist. In result, the discriminant analysis method was hard to qualify the assumption of the equality of covariance matrices within constitutional groups. Moreover, without BMI, the decision tree and neural network methods were very sensitive to the change of the analysis data. Therefore, the Logistic regression and the decision tree is recommended on condition that the decisive factors of constitution are well concerned.

Visual evaluation of chest radiograph images is the most practical and effective method. This study compared the Body Mass Index, waist circumference, and mAs with chest radiographs of 351 women. The Bureau of Radiological Health method was used to evaluate the image quality of chest X-ray images by anatomical and physical methods. The average age of the subjects was $30.17{\pm}4.73$ and the average waist circumference was $66.91{\pm}4.67cm$. The mean Body Mass Index value was $20.21{\pm}2.23$, the mean value of mAs was $3.04{\pm}0.78$, and the mean value of Bureau of Radiological Health was $79.83{\pm}8.45$. When the Body Mass Index value increased, waist circumference and mAs mean value increased. The mean value of Body Mass Index was statistically significant(p<0.05) in Group 4 compared to Groups 1 and 2, with increasing Body Mass Index. Exposure control of the automatic exposure control system is considered to be well performed according to body thickness or Body Mass Index at the time of chest radiography. As the Body Mass Index increases, the thickness of the body increases and the breast thickness of the woman also increases. Therefore, it is considered that the exposure amount is changed by the automatic exposure control device to affect the image quality.

Generally, the osteoporosis of a middle-aged women have been reported that was a high risk in underweight, but the obese women have feasible osteoporosis. Therefor, the subjects were 120 middle-aged women that were diagnosed with osteoporosis in the bone mineral densitometer (BMD), this study was done for the purpose of analyzing the relationship between osteoporosis and body mass index (BMI) of the middle-aged women. We were determined BMI which was less than 18.5 underweight, 18.5 to 22.9 normal, 23.0 to 24.9 overweight, 25.0 to 29.9 obesity and extremely obesity were more than 30. When we examined the BMI distribution of the subjects, it was 2 women (1.7%) for underweight, 18 women (15.0%) for normal, 19 women (15.8%) for overweight, 75 women (62.5%) for obesity and 6 women (5.0%) for extremely obesity. Also, the relationship between osteoporosis and BMI of the subjects, it was the osteoporosis in 13 cases out of 18 (72.2%) with normal, in 14 case out of 19 (73.7%) with overweight, in 63 case out of 75 (84%) with obesity, in 5 case out of 6 (83.3%) with extremely obesity, besides, the osteoporosis usually marks the highest in a BMI with obesity. In conclusion, the result of analyzing the relationship between osteoporosis and BMI, we found out that the osteoporosis of the middle-aged women was high risk with obesity, and that was mostly higher the osteopenia rather than osteoporosis.
