We analyzed 121 age estimation clients who had visited oral medicine clinic, Chonbuk National University Hospital, from January 2000 to December 2007 to evaluate its characters in Jeonllabuk-do. The obtained results were as follows : 1. There was distinct difference in sex distribution(Male : 58.7%, Female : 41.3%) and more than half percent(55.4%) was over 50's. 2. The difference between registered and alleged age was the most in more than 5 years, and most of them were over 50's. 3. There were more clients who wanted to increase their age than to decrease and was no prominent difference in sex. Age estimation clients who wanted to decrease their age were predominant under 10 years old and in 20's, and those wanted to increase were predominant in 10's and over 30's. 4. The most reasons to correct age were related to welfare benefit. The purpose of age estimation was different according to each age groups; welfare benefit was the most over 50's, occupation in 40's and 50's, friendship in 30's and 40's, sibling-related in 50's, employment in 10's and 20's. 5. Age was estimated by the attrition of permanent tooth and pulp/tooth ratio from 20 years, root apex closure for 10's and calcification of permanent tooth under 10 years old. In cases that were difficult to estimate by use of the attrition of permanent tooth and pulp/tooth ratio, age was estimated by missing time of permanent tooth and the change of mandibular angle with age. 6. The estimated ages were close to alleged age in 77.7% of clients but the rest(22.3%) was close to registered age.
Anti-aging is one of the key words to have characterized Korean society, and Korean adults in their 40s and 50s are very interested in this word. In this study, their cognitive ages and body images which are expected to have been influenced by anti-ageing were determined and correlation between them was examined. A survey was conducted and 368 of 500 questionnaires were used in data analysis. Data were analyzed by descriptives, factor analysis, reliability analysis, correlation analysis, and multiple response analysis through SPSS 12.0. The results are as follows. First, the cognitive ages of Korean adults in their 40s and 50s showed to be 37.5 years old which are 9.1 years old younger than their average actual ages. Second, their attitudinal body images appeared to be composed of appearance orientation and appearance evaluation, and appearance orientation represented to be a little higher than appearance evaluation. In addition, it showed that the correlation between cognitive ages and the attitudinal body images was low and negative. Third, people in their 40s and 50s revealed to think good health and impression as ideal body images. It was found that they regarded a face as the most important body part for ideal body images and were sensitive of their weight. Forth, correlation between cognitive ages and variables of ideal body images was identified to be significant in 4 variables which are slender, shapely and slim figure and good body proportions. In conclusion, it was shown that Korean adults in their 40s and 50s recognized themselves to be 9.1 years old younger and, the younger they perceive themselves, the younger body images they want. Also, it could be confirmed that anti-ageing is a megatrend in Korean society.
This study was carried out to investigate the distribution of body composition, and to analyze its relationship to dietary behaviors and life style. The study subjects were divided into 3 age groups; 30' years (n = 78) 40' years (n = 71) and 50' years (n = 44). The data was collected by physical measurement (Inbody 230) and questionnaires. The rate of disease and general characteristics were higher in the 50 year old group than in the other groups. Average amount of body water, protein, mineral and body fat were 29.0 kg (50.4%), 7.7 kg (13.4%), 2.8 kg (4.8%), 18.7 kg (31.5%), respectively. The rate of menopause was significantly different with increasing age. Menopause was 1.3%, 9.1%, 79.6% by age respectively. Body fat percent was significantly increased and body water decreased with age (p < 0.01). The fat composition was higher and the mineral content was lower in 50' year old group. Dietary behavior scores of 30' year old group was significant lower than in the other two groups (p < 0.001). The means of salty eating, skipping meals, fruit intake and food habits total point were significantly higher in the 50 year old group than in the other groups. There were significant positive correlations between age, BMI, waist hip ratio respectively (p < 0.01). There were significant negative correlations between age and body water, body mineral, skeletal muscle (p < 0.01, p < 0.05, p < 0.01). The results of this study suggested that nutritional management and education for adult women differ by age group.
This study was performed to narrow down the Sizing System for Female Adult's garments(KS K 0051) following age target and body shapes. The study was based on the sizing system and the anthropometric measurements, called Size-Korea, which were surveyed in the years 2003 and 2004. At first, the subjects of the survey were classified into 4 age groups, $18{\sim}24,\;25{\sim}34,\;35{\sim}49\;and\;50{\sim}59$, based on the most significant differences of body sizes. Secondly, the ranges of four key dimensions - height, bust, waist and hip-of normal sizes were identified through analyzing Rohrer index and percentile. The selected sizes within the ranges were grouped by the drop which was the subtraction of bust girth from hip girth. In conclusion, there was the most frequent drop for each age group; 9cm drop for the $18{\sim}24$ years old group, the 6cm drop for the $25{\sim}34$ years old and $35{\sim}49$ years old and 3cm drop for $50{\sim}59$ years old. The upper body garment sizes of the same drop and target ages could be merged to 10 to 12 sizes, which were remarkably smaller than the Female Adult garment sizing system, and further to 2-5 sizes, considering the percentile importance. However, $50{\sim}59$ years old group needed to be analyzed in different ways, because the number of subjects of normal size in the age decreased rapidly, that the normal sizes for them were very limited. In addition, the reference body sizes of each garment size were apparently different when they were compared to each age groups. These basic data for garment size specification could be usefully adapted for the apparel companies' own sizing system according to their age target and body shapes, to achieve efficient production and better fit.
Purpose: Atrioventricular nodal reentry tachycardia (AVNRT) is less common in pediatric patients than in adult patients. Thus, data for pediatric AVNRT patients are insufficient. Hence, we aimed to analyze the patient characteristics, treatment, and any recurrences in pediatric AVNRT patients. Methods: We reviewed the records of 50 pediatric AVNRT patients who had undergone radiofrequency catheter ablation (RFCA) between January 1998 and December 2016 at a single regional center. The patients were aged ${\leq}18years$. Results: Among 190 pediatric patients who underwent RFCA for tachyarrhythmia, 50 (26.3%; mean age, $13.4{\pm}2.6years$) were diagnosed as having AVNRT by electrophysiological study. Twenty-five patients (25 of 50, 50%) were male. Twenty patients (20 of 50, 40%) used beta-blockers before RFCA. All patients had no structural heart disease except 1 patient with valvular aortic stenosis and coarctation of the aorta. RFCA was performed using the anatomic approach under fluoroscopic guidance. The most common successfully ablated region was the midseptal region (25 of 50, 50%). Slow pathway (SP) ablation and SP modulation were performed in 43 and 6 patients, respectively. Complication occurred in 1 patient with complete atrioventricular block. During follow-up, 6 patients had recurrence of supraventricular tachycardia, as confirmed by electrocardiography. Among them, 5 underwent successful ablation at the first procedure. In 1 patient, induction failed during the first procedure. Conclusion: RFCA is safe and effective in pediatric AVNRT patients. However, further research is needed for establishing the endpoints of ablation in pediatric AVNRT patients and for identifying risk factors by evaluating data on AVNRT recurrence after RFCA.
This thesis was to investigate sex defferencd by employing the methodes of Bernadskij's and it's modification by means of the evaluation of pH of dentin in 162 extracted teeth. The obtained were as follows: 1. In 72% of all experinments, pH of human dentin substance was higher in female than in male. Mean pH was 13.175±0.031 in male and 13.245±0.030 in female. 2. After comparative studies on each pH in anatomical region of tooth arrangement, the sex difference of pH was most obviously showed in molars. 3. In pH change according to ages, the 30's was the highest in male and the 20's in female, also pH showed decresing tendency by the increasing of age in both male and female. 4. There was no pH difference in anatomical regions of tooth arrangment. 5. Mean pH was 13.282±0.013 in under 50 years of age and 13.282±0.022 over 50. It proved that pH was higher in under 50 years of age than in over 50.
The authors had studied the oral environmental changes by salivary salivary pH, amount, periodontal Index in patient with active pulmonary tuberculosis patients. Among the subjects, The experimental group was consisted of 100 patients (50 males and 50 females) of 20-29 years and 100 persons of control group (50 males and 50 females) of 20-29 years. The measurement of salivary amount was performed with wide mouthed plastic (2 Inches) bottle for avoidance of Ionization of SiO2 by using of glass bottle and salivary pH was checked by pH meter 27 radiometer Copenhagen. The results are as follows : 1. The slivary pH does not appear to be characteristic of tuberculous paticents. 2. The obtained salivary amount indicated no significant to the tuberculous patients as compared to the obtained supposedely wealthg individuals. 3. The Russel Index wasfound higher and there had found more periodontal involvement(3 times than normal) in the experimental group.

Predicting the future is at once both an opportunity and a challenge. Predicting what changes will take place in the poultry industry over the next century is certainly an opportunity to review the past and use this as a means of predicting the future. As the poultry industry became commercialized only during the last 50 to 60 years. the developments that will take place in the next 50 years will no doubt be phenomenal. (omitted)

We'd experienced 172 cases of fatty liver among 3,713 cases, that was examined by ultrasonography at medical department, Dae Han Kyoyuk Ins. company for recent one year from november, 1984 to November, 1985. The conclusions are as follows; 1. The possessing rate of fatty liver is 4.63% in total caees 138/2234 male(6.18%), 34/2234 female(2.3%) and that in male is 2.7 times than female. 2. In the distribution of fatty liver for age, the group of $21{\sim}30$ years are 9/564 cases(1.6%), the group of $31{\sim}40$ years are 74/1777, the group of $41{\sim}50$ years are 59/976(6.05%),the group of $51{\sim}60$ years are 29/240(12.08%) with age, the possessing rate of fatty liver was increased. 3. For sex, age, the possessing rate of fatty liver, in male $21{\sim}30$ years 8/329 cases(2.43%), $31{\sim}40$ years 64/118(5.72%) $41{\sim}50$ years 43/618(6.96%), $51{\sim}60$ years 22/134(16.42%) and in female, $21{\sim}30$ years 1/335(0.3%), $31{\sim}40$ years 10/659(1.52%) $41{\sim}50$ years 16/358(4.47%), $51{\sim}60$ years 7/106(6.6%) and then in total sex, with age, the incidence was increased. 4. 172 cases in fatty liver, we could find 109 cases of obesity(63.37%), in female the rate was more. 5. The abnormal was 13.95% for the level of Fasting blood sugar of fatty liver 172 cases, the average level of blood sugar was high markedly in female, on the contrary the number of abnormal blood sugar level was high in male. 6. In liver function test of 172 cases of fatty liver, the abnormal of sGOT value was 18.6%, sGOT value 20.93%, average of abnormal group in sGOT value was 52.62 units, sGPT value 56.99 units.
It has been suggested that vegetables protect the cardiovascular system in part by attenuating blood pressure. The purpose of the present research was to examine blood lipids according to vegetable intakes. Anthropometric measurements, blood pressures, nutrient intakes using the 24-hour recall method, and serum lipids of <50th percentile vegetable intake group (<50th percentile VIG; men=66, women=111) and ${\ge}50th$ percentile vegetable intake group (${\ge}50th$ percentile VIG; men=83, women=94) were estimated. The average age, height, and BMI were 54.7 years, 158.2 cm, 62.2 kg, and $24.9kg/m^2$ for <50th percentile VIG and 53.7 years, 159.6 cm, 63.0 kg, and $24.7kg/m^2$ for ${\ge}50th$ percentile VIG, respectively. The daily food intake of the ${\ge}50th$ percentile VIG was significantly higher than that of the <50th percentile VIG (p<0.001). Also, daily intakes of cereals (p<0.001), legumes (p<0.05), nuts (p<0.05), vegetables (p<0.001), and fruits (p<0.05) of the ${\ge}50th$ percentile VIG were significantly higher than those of the <50th percentile VIG. The daily energy intakes of ${\ge}50th$ percentile VIG and <50th percentile VIG were 1342.7 kcal and 1782.0 kcal (p<0.001), and most nutrient intakes of the ${\ge}50th$ percentile VIG was significantly higher than that of the <50th percentile VIG. Serum cholesterol of the ${\ge}50th$ percentile VIG were significantly lower than that of the <50th percentile VIG (p<0.01). Also, vegetable intake showed significantly negative correlations with total cholesterol (p<0.05) and LDL-cholesterol (p<0.05). Based on these results, it should be emphasized that increase of vegetable intake improves the blood lipid profile.
