The esthetics of chin contour is very important in facial deformities, and the quantity of soft tissue overlying the symphysis can be helpful to the correct diagnosis and surgical treatment for optimal facial harmony. The objectives of this study is to measure the different thicknesses of skeletal and soft tissues of chin on lateral cephalometric radiographs, to obtain the mean values of normal Korean adults, and to investigate the relative proportions of skeletal and soft tissues of chin. The results were as follows ; 1. In normal Korean adults, the relative proportions of the distances of soft tissue toward skeletal tissue were 1.5 in B point and 0.95 in Pg, and there were significant difference between male and female in the relative proportion of Pg (p<0.05). The relative proportion of the distances of vertical soft tissue toward horizontal soft tissue of Me was 1.91, and there were not significant difference between male and female. 2. In normal Korean adults, the distances of skeletal and soft tissues of chin showed no correlation, but the distances of vertical and horizontal soft tissues of Me showed high correlation (p<0.01). 3. In normal Korean adults, the correlations among the distances of each skeletal and soft tissues of chin were significantly high in both of male and female (p<0.01). Among the relative proportions of the distances of skeletal and soft tissues, the correlations of the proportions of B point and Mp and the proportions of Mp and Pg were significantly high (p<0.01).

In order to collect some necessary data to promote correcting the toothbrushing technic on the Korean public, the author had examined the number of present teeth on which had cervical abrasion and the most basic home dental care in 2,000 Korean male and female adults from 19 to 52 years in the age. Then, the cervical abrasion experience rate and the cervical abrasion experience teeth rate were calculated and evaluated. The obtained results were as follows: 1. Cervical abrasion experience rate was 32.45% 2. Cervical abrasion experience rate was gradually increased by ageing. 3. Cervical abrasion experience rate in male adults was higher than that in female adults. 4. Cervical abrasion experience rate in the lower jaw was higher than that in the upper jaw. 5. Cervical abrasion experience rate of the teeth at the right side was higher than that of the teeth at the left side. 6. Cervical abrasion experience teeth rate was 3.82%. 7. Cervical abrasion experience rate was highest on the first bicuspid, and followed in the sequence of the second bicuspid, canine, first molar, incisors, and 2nd and 3rd molars.

The author investigated the modified Broca's index that could be applied to Korean adults, what is called Korean Broca's Index, with 2322 apparently healthy subjects of 20-59 years old in order to obtain the index which could be used to estimate the standard body weight of Korean adults. The obtained results were as follows: 1. Linear regression equation of body weight to height was Y (weight in kg)=0.7195 X (height in cm)-57.9746 in male, and V (weight in kg)=0.4288 X (height in cm)-16.6528 in female. 2. Estimated constant that could be applied to Korean Broca's Index was 0.93 in male and 0.89 in female, and these sexual difference was statistically significant. (P<0.01)

Objectives: We tried to confirm physical activity of 1,000 Kcal per week was a meaningful point in controlling coronary artery disease risks in female older adults. Methods: Participants were 66 female older adults recruited from senior welfare center. Participants were provided with accelerometer (e-step, Kenz, Japan) for measuring daily energy expenditure. Graded exercise test was done for measuring aerobic fitness. Blood glucose and lipid were analyzed. Framingham risk score was calculated based on blood glucose, blood lipid, and smoking. These variables were compared between the group expended more than 1,000 Kcal/week and the group with energy expenditure below 1,000 Kcal/week. Results: The group expended over 1,000kcal/week showed to be superior to the counterpart group in following variables; AC(Abdominal Circumference), %BF, $HR_{rest}$(resting heart rate), $VO_{2peak}$, FBG, LDL-C, TG, BDI-II, QOL, AR(Absolute Risk), RR(Relative Risk). Conclusions: The group expended over 1,000 Kcal/week was likely to have less probability in CAD than group expended less than 1,000 Kcal/week. The result of this study suggests the important role of active daily life that can be replaced with that of regular exercise especially for those who are not available to do structured exercise.

Objectives: Despite the considerable interest in the increase in obesity particularly of socially disadvantaged group in Korea, how obesity varies according to various socio-demographic characteristics still remains largely unanswered. To further develop the understanding of obesity in Korea, the present study focuses on the possibility that the relationship between educational attainment and obesity varies across age. Methods: Using 2010 Korea National Health & Nutrition Examination Survey (KNHANES), this study divides the adults into male and female groups and examines the interaction effect of age and educational attainment on obesity through binominal logit models for each group. Results: The most educated male group is more likely to be obese than those who did not complete high school. And the relationship between male's educational attainment and obesity does not significantly change across age. In contrast to male's obesity pattern, female educational attainment has a significant negative association with obesity. The gap in obesity across educational groups converges after middle ages in female. Conclusions: Health policies should pay more attention to those who are more vulnerable to obesity risk in order to effectively reduce obesity.

The author was performed to investigation of current status of prevalence for anti-hepatitis C virus (HCV) among the health-checkup adults in Jeonbuk province. A toal of 1,553 (male 1,046, female 507) serum samples were diagnosed by 3rd generation enzyme immunoassay (EIA) for anti-HCV. Total prevalence of anti-HCV was 0.9%, and prevalence of male and female were 0.8% and 1.2%, respectively. The prevalence of female was higher than male. According to ages group, prevalence of anti-HCV was highest in 60 age group, but it was not found in 20 age group. 14 samples with anti-HCV positive were diagnosed by EIA for hepatitis B virus surface antigen (HBs Ag), by chemiluminescence immunoassay (CLIA) for serum albumin, alanine transaminase (ALT) and asparagine transaminase (AST). Positive for HBs Ag was not found. The mean of serum albumin levels was 4.5 g/dL, and mean of ALT and AST were 34.3 IU and 31.9 IU, respectively. Through this study, I know that the prevalence of anti-HCV among adults in Jeonbuk, and suggest that the positive of anti-HCV persons who have lower serum albumin, normal to mild elevations in serum enzymes are chronic hepatitis.

My prior questionnaire has applied to 12 male and 29 female adults over 30-69 years old suffering from lumbago fer 6 months at least or having diagnosis of lumbago. I had the following conclusions from physical characteristics and cardiopulmonary capacity of lumbago Patients caused by obesity 1) The rate of lipids in the body was rotated to the maximum heart rate in the male group of lumbago patients (P<0.01). 2) The rate of lipids in the body was related to the maximum intake of oxygen(O2) in the male group of lumbago patients(P<0.01). 3) The maximum heart rae was related to the maximum intake of oxygen in the male group of lumbago patients(P<0.01). 4) The rate of lipids in the body was related to the maximum intake of oxygen in the female group of lumbago patients(P<0.05). 5) The rate of lipids in the body showed no relation to the maximum heart rate in the female group of lumbago patients(P>0.05). 6) The maximum heart rate was related to the maximum intake of oxygen in the female group of lumbago patients(P<0.01). 7) The cardiovascular system showed no relation te the function of the lungs in the male and female groups of lumbago patients(P>0.05) 8) The lung capacity per second of lumbago patients(FEV $1.0\%$) measured less than normal adults. 9) The maximum intake of oxygen(V02max) and heart rate was less than normal adults. Thus I summarized the conclusion so follows: the cardiovascular system of lumbago patients showed no relation to their pulmonary function, and the rate of lipids in the body Showed a correlation with the maximum intake of oxygen but the rate of lipids in the body showed no relation to their pulmonary function.

The purpose of this study is to evaluate the prevalence of voice disorders and the Korean voice handicap index in the elderly. For this study, 169 elderly performed two types of questionnaires and vowel /a/ prolongation. Self-reported voice symptoms and the Korean voice handicap index were analyzed and acoustic voice evaluation was performed by MDVP. The results showed that the prevalence of voice disorders in the elderly are significantly higher than that of adults in self-reports. In acoustic evaluation, 32.2% of the male elderly and 40.9% of the female elderly exceeded the thresholds of Jitter (%), Shimmer (%) and NHR. In addition, Korean voice handicap index scores of the female elderly are significantly higher than those of female adults. These findings indicate the high frequency of voice disorders in the elderly and the need to focus on this group. Additional studies on the voice related quality of life for the elderly are needed.

Grip strength is a very important basic data for ergonomic design of hand tools, grips, handles and etc.. Excessive grip strength is contineously exerted to handle the machines or tools, it might cause a musculoskeletal disorder such as cumulative trauma disorders. Capal tunnel syndrome is a typical nerve disorder anomg CTDs. In this paper we have measured the grip strength under sitting and standing posture for Korean adults ; 113 male and 105 female aged from 20' to the above 50' . And this paper performed statistical analysis for driving out characteristics between grip strength and anthropometric data. The results are as follows ; (1) The maximum girp strength is exerted under standing posture with the elbow in full extension(180 .deg. ) for both of male and female (2) There is significant difference in posture, sex and right left hand (3) Grip strength decreases with age for male, but it traces an inverted U curve for female (4) Grip strength has a correlation with age, weight, height, BSA, forearm length, hand length, thickness of wrist, circumference of wrist and breadth of wrist for male
