Purpose: This study was to investigate two-point discrimination(TPD) and related factors in rural community residents. Methods: The sample consisted of 68 people who have been living in rural community in June 2005 studied. TPD was measured from the tips of the thumb, index, middle, ring, and little finger of each hand with the TPD esthesiometer. The research was designed to be a cross-sectional measured study. SAS statistical software was used for the analysis. The characteristics of the study sample were described by mean and standard deviation(SD) for continuous variables and by frequency and percentage for categorical variables. The Student's t-test and analysis of variance (ANOVA) were used to compare TPD in gender and diabetes mellitus. A Pearson's correlation analysis was conducted for relationship among values of 5 fingers. Multiple regression analysis was performed to determine the factors associated with TPD. Results: A total of 68 residents were measured, their average $age{\pm}SD$ was $54.2{\pm}23.2$ years(range: $12{\sim}88\;yr$). The mean TPD for 5 fingers tips in dominated side was 4.76mm(thumb 3.98mm, index 4.22mm, middle 4.79mm, ring 5.17mm, and little finger 5.65mm, respectively). 4.91mm for thumb finger of women was significantly higher than 3.54mm that of men's in difference between gender(p=.01l4), also women(4.39mm) was higher than men(3.71mm) in median nerver area(p=.0318). There was a statistically significant difference in age(p=.0022), which were under age of 20(3.36mm), 30 years(3.61mm), 40 years(5.38mm), 50 years(4.84mm), 60 years(5.28mm), 70 years(5.18mm), and over age of 80(5.29mm). Factors related to TPD of fiver fingers by multiple regressions were gender(${\beta}=.03$, p=.0001). Conclusions: Taken together, gender and age were significantly associated with TPD. We recommend that further research should measure TPD by using larger sample sizes and more sensitive measurement instruments.

This study was designed to investigate age-related changes in body composition and cell mediated immunity. Male Sprague-Dawley rats were fed stock diet ad libitum and 12 rats were sacrified at 1, 4, 6, 12 months of age. Body weight Increased sharply from 1 to 4 months. and Increased steadily thereafter. The weights of liver, epididymal fat pads, and kidney increased in similar pattern as body weight, but their relative ratio to body weight decreased with age. The ratio of epididymal fat pads to body weight increased with age. The weight of extensor digitorium longus, coleus and plantaris increased from 1 to 4 months, but it decreased at 6, 12 months. The protein content of muscles decreased or increased through- out 12 months. The T cell proliferation response to Con A stimulation was significantly lower at 6 months than 1 month and lower at 12 months than 6 months.

In the past decade, deep learning has been applied to various medical image analysis tasks. Skeletal bone age estimation is clinically important as it can help prevent age-related illness and pave the way for new anti-aging therapies. Recent research has applied deep learning techniques to the task of bone age assessment and achieved positive results. In this paper, we propose a bone age prediction method using a deep convolutional neural network. Specifically, we first train a classification model that automatically localizes the most discriminative region of an image and crops it from the original image. The regions of interest are then used as input for a regression model to estimate the age of the patient. The experiments are conducted on a whole-body scintigraphy dataset that was collected by Chonnam National University Hwasun Hospital. The experimental results illustrate the potential of our proposed method, which has a mean absolute error of 3.35 years. Our proposed framework can be used as a robust supporting tool for clinicians to prevent age-related diseases.

The purpose of this study was the development of a scale to assess the daily hassles of school age children. The subjects were 398 third and sixth grade children selected from elementary schools in Seoul, Inchon, Taejon, Kwangju and Pusan. Instruments included a questionnaire composed of a 96-item Daily Hassles Coping Scale, demographic questions, a 27-item Children's Depression Inventory, the 42-item Han & Yoo Daily Hassles Scale for Children, and a 30-item Children's Behavior Check List for mothers. Mean, %, ${\chi}^2$, Cramer's V, Cronbach's ${\alpha}$, factor analysis and Pearson's r were used for data analysis. 82 items from the 96-item Daily Hassles Coping Scale were selected through the item discriminant method. (Cramer's V discriminant coefficients ranged from .36 to .79). Five factors were extracted from the lst and 2nd factor analyses. Subscales were "parent-related," "friend-related I," "study-related," "friend-related II," and "teacher-related" stress. Criterion validity of the 82-item scale was confirmed through significant correlations with the Children's Depression Inventory (r=.55) and the Han & Yoo Daily Hassles Scale for Children (r=.22). Internal consistency of this scale was high, including internal reliability of subscales. These results confirm this scale as a valid and reliable measure of daily hassles of school age children.

Purpose: The Cow's Milk-related Symptom Score (CoMiSS^TM), which considers crying, regurgitation, stools, skin and respiratory symptoms, was developed as an awareness tool for evaluating cow's milk-related symptoms. The scoring ranges from 0 to 33. A score ≥12 was proposed as being likely cow's milk-related and suggestive of allergy to cow's milk. This study aimed to determine the age-related CoMiSS^TM values in presumed healthy infants in Poland. Methods: This was a cross-sectional study conducted in well-child clinics in two locations. Parents of the presumed healthy infants aged ≤6 months were approached during a routine checkup/vaccination visit. The exclusion criteria were as follows: presence of acute or chronic diseases, preterm delivery, treatment with therapeutic formula, and use of any food supplements (except vitamins) or medications. Results: Data from 226 infants were obtained (median age [Q1-Q3], 4 months [3-4]). The overall median (Q1-Q3) and mean (standard deviation) CoMiSS^TM values were 4 (2-7) and 4.7 (3.5), respectively. The 95th percentile was 11. Scores on some, albeit not all, components of the CoMiSS^TM significantly differed between age groups (crying, stools) or feeding type groups (stools and skin symptoms). Eleven children (4.9%) scored ≥12. Conclusion: This study adds to earlier age-related CoMiSS^TM data by providing CoMiSS^TM values in presumed healthy infants in Poland.

This study was conducted to examine arthritis patients' knowledge level and its related factors. Data were collected from 100 people who suffered from arthritis in Seoul, Busan, Daegu, Daejun, Junjoo, and Pohang from June 1, 2000 to August 31, 2000. The results of this study are summarized as follows. 1. 61.0％ of the subjects was female. The incidence rate of arthritis was higher in the higher age group, lower educated group, and thinner group. In the case of male, the incidence rate was higher in the groups of single, residents in big cities, and technicians. In the case of female, it was higher in the groups of the married, residents in towns or villages, and housewives. 2. Among the sources of obtaining the knowledge related to arthritis, 38.0％ of the respondents obtained the knowledge from physicians and 24.1 ％ got it from TV or Radio. 14.6％ of them obtained it from family members, neighbors, and friends and 14.3％ got it from newspapers, magazines, and pamphlets. Only 5.8％ of them obtained the knowledge from pharmacists. The sources showed significant difference in the variables of age, occupation, marital status, religion, place of residence, and education level. 3. 47.2％ of them thought that education related to arthritis was needed without fail, while 12.5％ thought that it was not necessary. In the question related to concern about arthritis, ‘no concern’ was 31.2％, while ‘concern’ was 7.8％ and ‘a little concern’ was 45.1 ％. 4. The knowledge level of arthritis was 7.35 ± 1.51 points on the basis of 11 points. It showed significant difference in the variables of age, occupation, education level, and economic status. 5. The knowledge was influenced by the variables of economic status, necessity of publicity, treatment period, occupation, education level, and age. The arthritis patients did not have enough knowledge of arthritis because the education was not provided well for them. Therefore, related professionals and organizations must develop education program of arthritis in order to educate them.

The objective of this study is to compare age-related differences of 15 characteristic variables estimated from SEMG signals, which were obtained from the old group(62 subjects) and young group(72 subjects). The SEMG signals were recorded from biceps brachii muscle under sustained isometric elbow flexion contraction with constant load(4kg dumbbell) during 30 seconds. Ten time domain (ARV, RMS, MSA, MTA, ZC, MSF, MTF, MSD, MTD, MSS) and five frequency domain(MNF, MDF, $f_{max}$, $P_{max}$, $P_{to}$) variables were extracted from the SEMG signals and then statistically analyzed, respectively. The findings of the analysis indicate significant age-related differences in the SEMG signal during constant load contraction.
