Purpose: The purpose of this study was to investigate homebound status and significant related factors for community-dwelling female elders according to age. Methods: The participants were female elders over 65 years of age registered in public health centers. Data were collected by interviewing the elders, who voluntarily completed the entire survey. For data analysis, descriptive statistics and multiple logistic regression were performed using SPSS version 18.0. Results: There were statistically significant differences in homeboundness and related factors between the young-old (65 to 74 years of age) and the old-old (75 years of age or older). The level of homeboundness of the old-old was higher than that of the young-old. Multiple logistic regression showed, timed "up and go", depression, and fear of falling as significantly associated with homebound status of the young-old, while hand grip strength (right), timed "up and go", static balance ability, severity of urinary incontinence, and fear of falling as significant for the old-old. Conclusion: The findings of this study indicate that homebound status and related factors for elders are different according to age, and therefore, interventions to prevent and help homebound elders get over being homebound should be developed according to age.

Usually, mage feature extraction methods are performed as a pre-processing step in many applications including image retrieval, object recognition, and image indexing. Especially, in the image texture analysis, texture feature extraction methods attempt to increase texture contrast to make it easier to extract the texture features from the image. One of the distinct textures in microscopic skin image is the wrinkle, and its features could provide various useful information for the age-related applications. In this paper, we propose a scheme to extract age-related features from the skin images and improve its accuracy in the skin age estimation.

Objective: There exist gender differences in pulsatile contour waveform. Women have a greater age-related increase in left ventricular mass than do men and more likely to experience symptomatic heart failure after infarction. SDPTG (the second derivative of photoplethysmogram waveform) is a noninvasive method for evaluating the pulse wave and is correlated with age and other risk factors for atherosclerosis. We studied the effect of gender on SDPTG and made clear why the gender differences appear. Methods: To study the effects of effect factors, including height and blood pressure, on SDPTG in the fourth decade, data on height, weight, PTD (pulse transit distance), blood pressure, serum lipid levels, and SDPTG were collected in 115 laboratory healthy men and women. SDPTG is derived from double-differential processing of fingertip photoplethysmography and consists of a, b, c, and d waves in systole and an e wave in diastole; SDPTG aging index (AI) was calculated as (b-c-d-e)/a. Results: There were significant gender-related differences of SDPTG AI, height, and blood pressure. Age, height, and mean blood pressure were respectively and significantly correlated with SDPTG AI. SDPTG is dependent upon age, height, and blood pressure. Restricting analysis to SDPTG AI, age, height, and mean blood pressure, yielded that there were gender-related differences in SDPTG AI (P<0.05) which were derived from those of height (F<0.001, df=l, P=0.994). Conclusions: These new data may help to explain previous findings about age-related differences in pulsatile contour waveforms and why gender differences of SDPTG appear. The results of this study suggest that SDPTG AI, used for evaluation of biological vascular aging, should be calibrated by height as well as age and blood pressure.

Purpose: This study was conducted in order to evaluate the epidemiological characteristics of?children with fall-down injuries according to age groups and to analyze the major trauma groups that were treated at the emergency room (ER). Methods: Among 1,222 children under age 6 who were treated at the ER from January 2008 to December 2009, a retrospective study was conducted through examination of medical records. The children were classified by age into 3 groups: infant, toddler, and pre-schooler. In each group, the differences between the causative factors that led to the fall-down injuries were analyzed. Also, ISS (Injury Severity Score) score above 4 was classified as major trauma, and an ISS score 0-1 was classified as a minor trauma. The relationship between major trauma and age group was also analyzed. Results: Through an analysis of child fall-down injuries, men (56.6%), toddler (47.3%), head-related symptoms (72.9%), furniture-related traumas (80.2%), and falls from less than a 1-m height (69.9%) were found to be common factors. Furthermore, in radiological studies, fractures and brain hemorrhages accounted for 16.9% of major traumas, and simple skull fractures were the most common (21.4%). Distributed according to age group, the factors relevant to fall injuries were fall height and head-related symptoms for infants, accident site, fall height and head-related symptoms for toddlers, and accident site for pre-schoolers (p<0.05). Also, headrelated symptoms and fall height were independent factors of major trauma in all age groups. However, major traumas (17.3%) were related to dumped trauma, fall height and accident site (p<0.05). Conclusion: This study was mainly about head-related injuries, and toddler were most common victims. The relevant factors for the major trauma were falling height for infants, accident site and falling height for toddlers, and accident site, falling height for pre-schoolers.

The purpose of this study was to investigate the relationships between demographic variables and seven aspects of clothing behavior of adult males, and to attempt to develop the measurement of men's clothing behavior. Age was ranked by five gradation (20∼60 ages) and socio-economic status was divided into three categories (high, middle, low) based on the subjects' education, occupation and economic status. Six aspects of clothing comfort, satisfaction, status symbol, conformity, fashion interest and clothing acceptance I were assessed with Koh's, Chung's and Lee's questionnaires. Clothing acceptance by line-drawing of clothing syles representing different levels of formality for occasions designed to measure the awareness of appropriate clothing category of business suits. The questionnaires in this study were administered to a sample of men living in Seoul. The sample was drawn by the random-cluster sampling method. The data from 362 respondants were analysed. To determine the internal validity of clothing behavior mesurement, factor analysis was computed, whereas to determine the reliability, Cronbach's alpha was calculated. The statistical methods adopted were correlation, one-way ANOVA, and multiple regression. The results obtained in this study were as follows: 1) As for clothing behavior instruments, items dealing with status symbol and fashion nterest were proved to be satisfactory as a measurement of adult males. Eight factors emerged on clothing acceptance Ⅱ, most of which were representing unappropriate clothing choice for occasion. 2) Demographic variables were significantly related to the adult males' clothing behavior. (1) Age was positively related to clothing conformity but negatively to fashion interest. (2) Socio-economic status was positively related to clothing satisfaction, status symbol, and fashion interest but negatively to clothing confort. (3) When age was controlled, socio-economic status was negatively related to comfort in 40∼50s age group only, and negatively related to clothing conformity in 20∼30s age group only. (4) Four subscales of clothing acceptance Ⅱ representing unappro-priate clothing practice for selected occasions were negatively related to age and/or socio-economic status.

Objectives: This study aimed to identify the relationships of oral and systemic health-related characteristics with health-related quality of life (EQ-5D) in the elderly, and factors related to quality of life were compared according to age subgroups classified as either younger (young-old) or older (old-old) than 75 years of age. Methods: Data acquired by the Sixth Korean National Health and Nutrition Examination Survey(KNHANES) from 2013 to 2015 were used, and the research target was 3,124 people aged 65 years or older. A complex samples general linear model was used to identify health-related quality of life factors. Results: Education, economic activity, depression, stress, regular walking, self-rated oral health, pronunciation problems, and unmet dental care had significant effects on quality of life in both young-old and old-old participants. Marriage, income, number of systemic diseases, sleeping, and chewing inconveniences were significant factors for the young-old but not in the old-old participants. Instead, obesity and drinking were identified as significant factors in the old-old participants. Conclusions: We reaffirmed that factors affecting health-related quality of life in older adults differed by age group. We also confirmed the impact of oral health-related characteristics on this quality. Therefore, to improve quality of life for older adults, it would be efficient to divide groups by age and develop and implement programs that take relevant factors into consideration.

This study was performed to measure the various dimensions of the hand for Korean adults. Three hundred and eighteen males and two hundred and sixty females, age ranged 18 to 60, participated in this study. Thirty-five dimensions were selected to measure. Subjects were divided into three age groups, 18 to 29, 30 to 39, and 40 to 60, for each sex. The data were analyzed to see the differences between the age groups and sex by using SAS program. The results showed that the measurements related to breadth and thickness tended to increase as the age increased. Wrist breadth, index finger breadth(distal), index finger breadth(proximal), thumb breadth, and index finger thickness(proximal) increased as the age increased for both males and females (p<0.05). However, the measurements related to length tended to increase as the age decreased. The relationship between the parts that are length related showed high correlation. Hand length showed high correlation with palm length, middle finger length and index finger length. Males' were significantly greater than females' in every dimension (p<0.05). Also, the results of this study were compared with the data of Japanese and U.S. army. The results of this study can be used to design the hand related products.

The purpose of this study was to identify the physical characteristics of early adolescent girls by age. A total of 529 girls aged between 10 and 14 were measured and data were collected from 42 anthropometric and 41 photographic measurements per a person. SAS 8.1 was used in data analysis including means, standard deviations, t-test, Duncan test and frequency analysis. The results of this study are as follows. Most items related to height and length increased significantly at the age of $10\sim11$ and the growth slowed down at the age of $13\sim14$. As for items related to circumference, the growth rate was high at the age of $11\sim12$, and gradually slowed down afterward. Out of circumference items, hip circumference showed the highest growth rate. As for items related to thickness and width, thickness-related items grew quickly at the age of $10\sim12$, and among which bust thickness showed the highest growth rate. As for drop, the difference between hip circumference and waist circumference was most remarkable, but the difference between hip circumference and bust circumference was not large. The largest number of subjects had their menarche during the age of $11\sim12$ and, after menarche, their horizontal growth became active.

PURPOSE: This study examined the prevalence and specific risk factors in males aged 40-49 years with the coexistence of age-related loss of skeletal muscle mass and obesity (CALSMO). METHODS: The current study analyzed the data obtained from a cross-sectional study involving a sample of 1,218 men who resided in the community and fell within the age range of 40 to 49 years. Multiple risk factors were examined: age, height, weight, body mass index, waist circumference, skeletal muscle mass index, smoking and drinking habits, systolic and diastolic blood pressure, fasting glucose levels, and triglyceride and cholesterol levels. All data were analyzed via complex sampling analysis. RESULTS: The coexistence of age-related loss of skeletal muscle mass and obesity in males was 2.94% (95% CI: 2.06-4.17). The clinical risk factors were low height, high weight, body mass index, waist circumference, skeletal muscle index, systolic blood pressure, diastolic blood pressure, and fast glucose (p < .05). CONCLUSION: The study identifies the prevalence and risk factors for CALSMO among adults in the community. These findings contribute to the existing literature on CALSMO and highlight potential risk factors associated with CALSMO development in males aged 40-49 years.
