In this study, foot shapes were compared between the men in their 20's and 60's, with the application of 3-dimensional measurement data, and the classification was established in consideration of each of their features. The results are as follows: 1. The investigation into the differences between the groups for the 3-dimensional measurement items of the men in their 20's and 60's indicated that those in their 20's had larger values than those in the 60's age group for all of the length items, while those in the 60's age group had larger values for all of the angle items. 2. The analysis of the constituting factors for the feet of those in their 60's and 20's resulted in the 7 items for the 20's age group and 8 items for those in the 60's age group. 3. The comparison of foot classifications for the 60's age group and 20's age group presented 3 types each for both groups, but the features of each type was different. To examine each characteristic by each type and age group, following can be determined of the 60's age group. Type 1 had a thick instep, high malleolus position and heel and a thick formed ankle. Type 2 the entire foot was small, and the big toe was formed in such a way that it tened to bend toward the inside. When the whole size compared with similar Type 1, Type 3 had a low instep, a low heel, the big toe did not bend and ankle form was thin. The following can be determined of the 20's age group. Type 1 had narrow width a thin ankle and the big toe was formed in such a way that it bended toward the inside. Compared with length, Type 2 had wide width and a thick ankle. Type 3 had a larger overall size, thick instep and wide and the toe was big, but the characteristic of inside and outside of a malleolus position was low and the big toe's form showed no tendencies to bend.

Somatotypes in the lower torso and legs of adult females were classified and discriminated. Then their distribution according to the age groups was studied. The subjects were 343 females of 18 to 49 year-old. 36 anthropometric and 21 photographic measurements were taken to each subject. The results were as follows: 1. The somatotypes in the lower torso and legs were classified into 4 types and their differences were shown by analysing factor scores and anthropometric values according to each somatotype. 2. The shape characteristic of tile classified somatotypes was represented by the rating scale of Heath-Carter. 3. The lateral silhouettes of 4 types were compared with balanced type which is type 3 in this study. 4. Individual somatotype in the lower torso and legs could be discriminated from the measured anthropometric data without modifying the data. Anthropometric data, which are needed for discriminating individual somatotype, are waist circumference, posterior waist height, and hip circumference. 5. The distribution of the somatotypes in each age group showed that the dominant somatotype of each age group was different and any somatotype was shown in a specified age group but rarely in other age group.

In this study, the trunks of adult females were classified into several kinds of somatotypes and their distribution according to the age groups was shown. The subjects were 343 females of 18 to 49 year-old. The results were as follows: 1. The trunk somatotypes were classified into 5 types. From factor scores and anthropometric values according to each somatotype, it was shown that the somatotype was classified by the relation between the variables of vertical size and those of horizontal size. 2, As the characteristic of the classified somatotype was represented by the scale and its lateral silhouette was suggested, the characteristic of the classified somatotype was Quickly undertook. 3. By suggesting the canonical discriminant function with the unstardardized canonical coefficient, individual trunk somatotype could be discriminated from the measured anthropometric data without modifying the data. 4. From the frequency distribution of the somatotypes in each age group, the dominant somatotype of each age group was shown differently.

Objectives : The purpose of this study was to evaluate the correlation of 3 methods of bone age measurements. Methods : 102 children(49 boys, 53 girls) were involved in this study. We measured the height, weight and bone age based when they visited for the first time. We measured bone age using BoneAge of Sunlight Co.,Ltd. Two of the bone age measurement methods, Greulich-Pyle and Tanner-Whitehouse, were used to analyze the left dorsopalmar hand-wrist radiographs of 102 children who visited in Department of Pediatrics, O O University Oriental Hospital. This study was designed to investigate the correlation of the bone age between two methods. Results : The bone ages were related with age, height, weight and BMI according to this study(P<0.01). Each bone age assessment method had statistically significant correlation to each other(P<0.01). Conclusions : The ultrasound transonic velocity of inferior radiocarpal joint will become a sufficient diagnostic tool of bone age assessment if measurement error can be minimized by proper effort.

We collected age determination cases which were done at Yonsei university dental hospital, department of oral medicine from 1976 to 1999 to analyze it's tendency among Koreans. We analyzed 435 clients cases which were stored by age estimation program from January 1993 to December 1999. The results are as follows: 1. There were no significant difference in the sexual distribution (male : 52.0%, female : 48.0%) and more than half percent (51%) were 20's and 30's. 2. Among the age determination clients, those who wanted to decrease their age (50.3%) and those who wanted to increase their age (49.7%) shows similar in number. And the former case were predominant in the female clients, but the latter case in the male clients. Also the clients below six years of age were predominant in the former case, but the clients more than sixty were predominant in the latter case. 3. The purposes of age correction showed different distribution for ages: job or employment for 20's and 30's, marriage for 20's, registration for school for below six, welfare and other social services for 50 and older. 4. Age was estimated by Nolla's growth stage for 12 and under, calcification of the second and third molar for 12~20, and for 20 and over, Takei's tooth abrasion model was used. 5. The alleged age was in accordance with the documents and other information given by clients, but in the 20.6% of the estimation cases, the alleged age was discarded. In the results of the analysis of age determination cases in Koreans, many of the cases resulted from our historical turbulence and social distinctiveness, causing an increase in the necessity for age correction in each age group. For more accurate determination for each age group, further studies with Koreans must be done continuously.

This survey was conducted on a total 672 pulmonary tuberculosis patients who were registered at certain health center in Busan, during the period from July 15th to August 31st, 1977, based on Modified Cornell Medical Index(CMI) consisting of 70 questions. Number of 'Yes' response of an individual patients was collected by each large section of Modified CMI. The each number of 'Yes' response was standardized by mean of Z scoring. Z score was obtained by following formula. Z=50+10(Xi-m)/s M : means of 'Yes' response by each section for all subjects s : standard deviation of the mean Xi : number of 'Yes' response by each section in an individual patients The results of obtained were as follows: 1. The number of investigated cases were 672 (459 males and 213 females). The most prevalent group was 20-24 years old group as 18.4% by age, moderate advanced group as 50.8% by radiological diagnosis, INH+PAS+SM group as 34.7% by antituberculotics and unemployed group as 59.9% by occupation. By bacteriological examination of sputum, the rate of negative group was 60.5% and positive group was 39.5%. 2. Z score of complaints by sex was higher in female as 52.4 than in male as 48.9 in general. By radiological diagnosis, there was decreasing tendency with age in male but increasing tendency with age in female. 3. By age group, Z score of complaints was increasing tendency with age in male but there was non-significant differences in female. 4. By bacteriological examination of sputum, the Z score of complaints was increasing tendency with the more discharged bacteria in both sex generally. 5. By antituberculotics, INH group was revealed the highest Z score of complaints as 50.4 in male and INH+PAS group was the highest as 51.21 in female. 6. By occupation, agricultural and fisherman group was the highest as 53.5 and the next group was professional, technical and related workers, unemployed and sales workers in that order.

This paper intends to investigate the correlation of 12 MDVP measurements with age, sex and body-size of sampled healthy patients. In order to extract pitch and 12 MDVP parameters efficiently and display the correlation of each parameter easily, we developed the speech analysis program using C/C++ and MFC development tool. The sample group consists of 205 males and 343 females with ages 9-81. We collected vowel voices /a/ and 8 body-size measurements from them. Body-size values were taken at 8 different torso positions of each person. We analyzed the matched voice samples and body-size measurements by the developed speech analysis program and SPSS program. The result shows that a typical characteristic age-F0 pattern that F0 of male subjects are rapidly decreased after mutational period and have stable state with age and that of female subjects are slowly changed by overall age. In MDVP, age-STD in males, age-sPPQ in females relationships are especially similar to the age-F0 relationship. In case of male group, sPPQ(0.316%), Jitt(0.04%), Shim(0.25%), APQ(0.28%) variables are increased with age after mutational period. And Jitt(0.042%), sPPQ(0.219%) of females group are increased with age too. In cases of height, weight and BMI there exists a weak correlation with MDVP, which shows a correlation coefficient below 0.25 about male and female groups. The survey of correlation relationship between 8 body-size measurements and MDVP shows a insignificant statistical result by only just having the correlation coefficient maximum in M8-8 and F0(-0.394%) for males and M8-6,7(-0.368%, -0.364%) for females.

This paper was performed to obtain the data applied to use of synthetic lightweight aggregate concrete affected by alkali silica reaction. The results obtained were summarized as follows : 1. The expansion of each type concrete was increased with increase of curing age, respectively. Also, at the curing age 90 days, the rate of expansion of type A, B, C and D concrete was increased 0.173%, 0.575%, 0.230% and 0.680%, respectively. Specially, the rate of expansion of type D concrete was shown 3.93 times higher than the type A concrete. The cracks width were increased with increase of expansion and at the 0.680% expansion, the maximum width was shown 0.5 mm. 2. The dynamic modulus of elasticity of each type concrete was increased with increase of curing age, respectively. At the curing age 30 days, the highest dynamic modulus of elasticity was showed at each type concrete, respectively. But, it was gradually decreased with increase of curing age at those concrete, respectively. Also, at the curing age A, B, C and D concrete was increased 24.3%, 33.7%, 28.1% and 37.0%, respectively. The rate of loss in type D concrete was shown 1.52 times higher than the type A concrete. 3. The ultrasonic pulse velocity of each type concrete was increased with increase of curing age, respectively. At the curing age 30 days, the highest ultrasonic pulse velocity was showed at each type concrete, respectively. But, it was gradually decreased with increase of curing age at those concrete, respectively. Also, at the curing age 90 days, the percentage loss of ultrasonic pulse velocity of type A, B, C and D concrete was increased 6.4%, 8.7%, 8.5% and 14.2%, respectively. The rate of loss in type D concrete was shown 2.21 times higher than the type A concrete. 4. The relation between dynamic modulus of elasticity and ultrasonic pulse velocity was highly significant. The dynamic modulus of elasticity was increased with increase and decreased with decrease of ultrasonic pulse velocity. Also, the decreasing rate of the dynamic modulus of elasticity was shown 2-7 times higher than the ultrasonic pulse velocity at each age, respectively. 5. The dynamic modulus of elasticity and ultrasonic pulse velocity were decreased with increase of expansion, and the decreasing rates were increased with increase of curing age. The increasing rate of expansion was shown higher than the decreasing rate of dynamic modulus and ultrasonic pulse velocity.

To determine the effect of air pollutants in Taejon City, we used medical insurance claim data for asthma and the data monitored from telemetry system of Ministry of Environment for air pollutants and meteorological factors. From November 1st, 1997 to October 31th, 1998, 95,629 asthma patients were covered by medical insurance at Taejon City. Subjects were composed of 49,563 males (51.8%) and 46.336 females(48.2%), and among the subjects, the proportion under 15 years old was 62.8% of the total. During the study period, daily mean concentrations of each air pollutants-So2, No2, CO, O3 and TSP-were 9.8 ppb, 17.6 ppm, 1.414 pp, 17.3 ppb and 60.6 $\mu\textrm{g}$/㎥, respectively, which were lower than each of the environmental recommended exposure levels, Through the simple correlation analysis between each air pollutants and meteorological factors, O3 was positively correlated with temperature, but negatively with relative humidity. TSP, SO2, NO2, CO were negatively correlated with meteorological factors, and these air pollutants except O3 were positively correlated with each other, O3 was correlated with TSP positively but the others negatively. Estimating relative risks of each air pollutant with the baseline general additive model, daily mean concentrations of TSP(Lag 0, 1, 4, 5day) were significantly associated with the increase of the asthma admission. Two age subgroups, under 15 and 15~54 have shown various association of all air pollutants concentration with the asthma admission. However, in case of over 54 age subgroup, only TSP(Lag 0 day) among all air pollutants was associated with the asthma admission. Each of ambient outdoor pollutant concentrations in Taejon City are significantly associated with the admission of asthma patients even though all concentrations in Taejon City are significantly associated with the admission of asthma patients even though all concentrations were much lower than the environmental recommended exposure levels. Therefore, continuous effort lowering air pollutant concentration and introducing an active environmental conservation policy should be implanted for preventing hazardous health effects. Considering major proportion of asthma admissions, high susceptibility and less confounding factors among the age subgroup under 15 will be a useful target population for assessing such health effect monitoring.
