Age estimations by forensic odontology play a great role in personal identification. The purpose of this study was to analyze the characteristics of age estimation cases in Korea. Surveying clients who requested age estimation at the Department of Oral Medicine, Kyungpook National University Dental Hospital from March 2012 to March 2013. The results were as follows: 1. On gender distribution, females(57.14%) were more than males(42.86%). The elderly with 50's and over 60's were majorities(89.28%) of clients, and no clients were below 40's. Most of clients were equal to and lower than elementary school graduate(69.64%). 2. The most frequent reason for age discrepancy between registered age and alleged age was mistakes by family or relatives(80.36%). The purposes of age estimation were welfare(62.50%), social relationship problem(12.50%), to find right age(10.71%), and occupation(8.93%). 3. In order of route to visit at Department of Oral Medicine, they were via government office(48.21%), acquaintances(21.43%), mass media(14.29%), and clinic(10.71%). Clients had high degree of comprehension on age estimation with forensic odontology (scored 7.03 out of 10). The 2/3 of clients were satisfied with present fee for age estimation. 4. The percentage on the proximity of estimated age to alleged age was 69.81%. 4(11.43%) clients were approved on age correction by court.

The objective of this study was to investigate the influence age-friendly environment factors on different age groups' life satisfaction. Data were taken from "2014 Survey on the Aged Society", with total of 1,000 participants divided into three groups: 300 youth participants from age 20 to 44, 300 middle aged participants from age 45 to 64, and older adults participants from age 65 and more. Performing ANOVA and multiple regression analysis showed that age-friendly environment factors had positive correlations with life satisfaction, regardless of the participants'age. However, the sub-dimensions of age-friendly environment that affected each age group was different. Among three sub-dimensions of age-friendly environment, which were housing factor, social participation factor, and community and health service factor, only housing factor affected life satisfaction of the youth group, while both community and health service factor, and housing factor affected life satisfaction of the middle-aged and the elderly groups. The result clearly presents that age-friendly environment factors are not only beneficial for older people but for people at all ages. Therefore, various measures need to be taken in order to increase the age-friendliness of communities, and improve the quality of life.

The purposes of this study were to investigate the perceived level of aging anxiety and the variables affecting the perception of aging anxiety by three different age groups and to find out what alternatives should be socially prepared to lower aging anxiety. We used survey data collected from 1,017 adults who are aged 18 and over and the subjects were divided into three age groups: 18-44 age group, 45-64 age group, over 65 age group. ANOVA and multiple regression analysis were performed to answer the research questions. Major findings of this study were as follows: 1) There was no difference in the perceived level of aging anxiety according to each age group, 2) 'perceived elderly stigma' was found to affect the perceived level of aging anxiety in all age groups, 3) 'perceived maximum age possible to work' was influencing the perceived level of aging anxiety in 18-44 age group and 45-64 age group, 4) 'perception of fairness to the operation of social systems' was a statistically significant variable for the perceived level of aging anxiety in the 45-64 age group and over 65 age group, 5) 'perception of age integration' and 'aging-friendly environment' variables had significant effects on the perceived level of aging anxiety only in over 65 age group. Suggestions for reducing the perceived level of aging anxiety have been proposed.

In order to evaluate the change in plasma and fecal mineral content of calves to 6 days of age, and to clarify the relationship between electrolyte status and fecal consistency in calves at 6 days of age, data were collected from 52 Holstein calves. Fecal DM and Na of calves decreased at 6 days of age, but fecal Ca, P, Mg, K, Fe and Zn increased. Plasma Ca, inorganic P, Mg, Na, and Fe as well as blood hematocrit and hemoglobin of calves decreased at 6 days of age, but plasma alkaline phosphatase increased. Colostral Ca, P, Mg, Fe and Zn decreased with time postpartum, but colostral Na and K were not affected. The high plasma Na and K of calves at 6 days of age were influenced by the values at birth. There were negative correlations between fecal DM and fecal Na, and fecal K, of calves at 6 days of age, negative correlations between fecal DM and plasma Na, with plasma K. Plasma and fecal Na as well as plasma and fecal K of calves at 6 days of age were increased by the occurrence of diarrhea. These results suggest that the electrolyte status of calves at 6 days of age is adversely affected by the occurrence of diarrhea, and high plasma K and Na of calves at 6 days of age may be partly due to the electolyte status of calves at birth.

The purpose of this study was to provide a brassiere size chart for making the well-fitted brassiere. The subjects are 2811 women whose range of age is 12 to 59. These woman were classified into 5 age groups by seniority ; age group 1(12~19), age group 2(20~29), age group 3(30~39), age group 4(40~49), age group 5(50~59). statistical differences of measurements were analyzed among 5 age groups through ANOVA. Correlation between measurements were analyzed by correlation analysis. In addition, new brassiere size chart and production rate tables were proposed in this study. The results of the study were as follows. 1) Most of the body measurements were significantly different among 5 age groups. The height was decreasing by getting older while weight was increasing significantly. The 3 girth measurements(top bust, bust, under bust girth) in breast, bust width, bust depth were apt to increase definitely. The 3 girth measurements had high Correlation coefficients among 3 girth mesurements. Therefore, it is valid to pick out cup size and under bust girth for representative items of size chart. 2) Under bust girth and cup size were chosen as 2 axes of brassiere size chart. From the dual distribution table whose intervals had been determined by KS size chart, 17 sizes, which had more than 2% of appearance, were suggested for brassiere size chart. Through these new size charts, the suggested brassiere sizes covered 82.5% of all subjects. The suggested brassiere size chart would be more helpful than KS size chart in making the well-fitted brassiere.

The absolute age of lapilli tuff in sedimentary formation that contains dinosaur fossils in the Boseong area, Korea was determined radiometrically against volcanic rocks below and above the fossil-bearing horizons. The sanidine in the lapilli tuff below the fossil-bearing horizon (Seonso formation) has an $^{40}Ar-^{39}Ar$ age of $81.l{\pm}1.4Ma$. The Pilbong tuff above Seonso formation has an $^{40}Ar-^{39}Ar$ age of $81.0{\pm}2.4Ma$. An andesite dyke intruding all sedimentary units yields an $^{40}Ar-^{39}Ar$ age of $42.4{\pm}2.5Ma$. Thus 81 Ma age can be regarded as the best estimate for the age of the Seonso Formation and the associated the dinosaur eggs. This age correlates well with dinosaur fossil finds in the Haenam and Koseong regions of Korea. The occurrence of dinosaur eggs and clutches attests to the existence of dinosaurs in southern Korea at least inCampanian times.

This paper is to investigate the effect of the curing temperature on strength development of concrete incorporating cement kiln dust(CKD) and blast furnace slag (BS) quantitatively. Estimation of the compressive strength of the concrete was conducted using the equivalent age equation and the rate constant model proposed by Carino. Correction of Carino model was studied to secure the accuracy of strength development estimation by introducing correction factors regarding rate constant and age. An increasing curing temperature results in an increase in strength at early age, but with the elapse of age, strength development at high curing temperature decreases compared with that at low curing temperature. Especially, the use of BS has a remarkable strength development at early age and even at later age, high strength is maintained due to accelerated pozzolanic activity resulting from high temperature. Whereas, at low curing temperature, the use of BS leads to a decrease in compressive strength. Accordingly, much attention should be paid to prevent strength loss at low temperature. Based on the strength development estimation using equivalent age equation, good agreements between measured strength and calculated strength are obtained.

Objectives: This study investigated the gender and age differential effect of major chronic diseases on activity of daily living (ADL) disability. Methods: Surveyfreq and Surveylogistic regression analyses were employed on the 2005 Korean National Health and Nutrition Examination Survey (KNHANES) with a sample of 3,609 persons aged 65 - 89. Results: After adjusting for potential covariates, stroke, among elderly men more so than women, had a 2-3 times greater odds of engendering ADL disability in the 65-69 (p < 0.05) and 70-79 age groups (p < 0.01). In comparison to elderly women, cancer, diabetes, and incontinence in elderly men was associated with a higher risk of ADL disability in the 70 - 79 age group (p < 0.05), and this association was also observed for pulmonary disease in the 80-89 age group. Among elderly women, however, a significant association between incontinence and ADL disability was identified in all three age groups. In addition, this association was found in pulmonary disease and diabetes in elderly women aged 70 - 79 years. Significant gender differences were observed in the association between stroke in the 60 - 79 age group and cancer in the 70 - 79 age group. Conclusions: Age and gender differences were observed in the effect of chronic diseases on ADL disability.
