Despite well-known benefits of physical activity for older adults, most older adults remain significantly underactive. The purpose of this study was to examine the effects of an inclusive, choice-based physical activity promotion program to increase lifetime physical activity levels of seniors on physical activity & health-related quality of life outcomes in older adults. The physical activity promotion program guided participants to choose activities that took into account their health, preferences, and abilities. It offered information on ways for them to exercise safely, motivate themselves, overcome barriers, and develop a balanced exercise regimen. A six-month comparison-group trial was conducted with older adults in community senior center. Changes in self-reported physical activity & health-related quality of life(SF-36) by group & within group were evaluated using t-test. Of 30 subjects, 22(73%) completed the trial. Subjects were aged 63 to 75 years(mean=$68.36{\pm}4.02$); 86% were female. The intervention group increased estimated caloric expenditure by 1975 calories/week in moderate intensity activities(MET${\geq}3.0$; p=.008), and by 2312 calories/week in physical activities of any intensity(p=.005). Between-group analyses showed that the changes were significantly different in both measures(p=0.17; p=032). The intervention group also significantly better scores on general health perception(p=.031) & vitality(p=.002). Individually tailored programs to encourage lifestyle changes in seniors may be effective and applicable to health care and community settings.

Objectives: This study was performed to investigate the associations of food security with socio-demographic characteristics, nutrient intakes and mental health status among older Korean adults. Methods: This study was conducted using data from the 2008-2010 Korea National Health and Nutrition Examination Survey (KNHANES). Subjects were 4,451 adults aged 65~98 years. Food security was measured using a self-reported question on food sufficiency of subjects' household. Based on the answers, study subjects were classified into secure, mildly insecure, moderately insecure, and severely insecure groups. Dietary intake was estimated by 24-hour dietary recall. Nutrient intake was assessed by dietary reference intakes (DRI). As for mental health status, the data on mental stress, depression, and suicide ideation were used. Results: Rate of food insecurity in older adults was 14.3%. Old age, being female, low education, low income level, living alone, and discomfort in daily living were more related to food insecurity. Means of nutrient intakes were significantly different according to food security status. Intakes of calcium, potassium, and vitamin $B_2$ were lower than recommended intakes in all groups. Consumption amounts of soy and soybean products, vegetables, mushrooms, fruits, vegetable oils, meats, eggs, seafood, and dairy products were lower in food insecure groups. Mental stress, depression, and suicide ideation were higher in food insecure groups independent of the gender and income level. Conclusions: These present findings suggested that food security is related to mental health as well as nutrition status in older Korean adults. A national system that include food and psychosocial support programs for the elderly should be considered in order to improve the overall health of older Korean adults.

Background: The purpose of this study was to assess the test-retest reliability of balance measurements in older adults using balance measurement system(Good Balance). Methods: The subjects consisted of 49 female and 20 male in community-dwelling older adults. This study used a repeated-measure design. Each subject completed all the different tests once and they were then repeated with 2 minutes in between. Repeated two-ways analysis of variance(ANOVA), representing two test times and both sexes, was calculated for each of the two dependent variables. Intraclass correlation coefficients(ICCs) were used to assess the test-retest reliability. Results: 1) There was not significant difference between test and retest for mediolateral sway speed and anterioposterior sway speed under conditions of normal standing with eyes open, normal standing with eyes closed and semitandem standing with eyes open. There was not significant difference between males and females for mediolateral sway speed and anterioposterior sway speed under conditions of normal standing with eyes open, normal standing with eyes closed and semitandem standing with eyes open. There were not the interaction effects between genders and test time under three conditions. 2) The reproducibility between test and retest was excellent for anterioposterior sway speed(ICC=.77) under condition of normal standing with eyes open, and for mediolateral sway speed(ICC=.76) and anterioposterior sway speed(ICC=.84) under condition of semitandem standing with eyes open. The reproducibility between test and retest was fair to good for mediolateral sway speed(ICC=.64) under condition of normal standing with eyes open, for mediolateral sway speed(ICC=.63) and anterioposterior sway speed(ICC=.75) under condition of normal standing with eyes closed. Conclusion: Balance tests in older adults using balance measurement system(Good Balance) demonstrated acceptable levels of reliability.

Purpose: This study was to investigate the socio-demographic and health factors affecting on the health related quality of life (HRQoL) in elderly by gender. Methods: Data of the study were derived from the fifth Korean National Health and Nutrition Examination Survey (KNHANES V-2, 2011). The subjects were older adults aged 65 years or more (673 male and 925 female) and the number of the sample was 1,598. The authors analyzed the data with the SPSS/WIN 21.0 program. Results: For male, the affecting factors on the HRQoL were education level, monthly income, and number of chronic disease. For female, affecting factors on the HRQoL were depression, stress, and age. The activity limitation and subjective health showed statistically significant relationship with the HRQoL for both male and female. Conclusion: Health care providers should consider the gender difference when they plan to design program for the improvement of HRQoL for elderly in community.

Objective : We present the difference of histopathologic changes of the internal elastic lamina (IEL) and collagen III in the superficial temporal artery (STA) between aneurysmal patients and non-aneurysmal patients. Also, the pathologic data with clinical features by comparative methods to validate the risk factor of the intracranial aneurysm are presented. Methods : Samples of the STA were harvested form 38 patients including aneurysmal and non-aneurysmal patients undergoing craniotomy. Paraffin-embedded sections were examined, using hematoxylin and eosin, van Giebson and mouse anti-collagen III staining techniques. Histopathological observations were ana lysed and correlated with clinical features such as presence of aneurysm, hypertension, age, and sex. Results : Twenty-seven patients had the intracranial aneurysm. Of these 24 patients were 50 years old or older. Nineteen patients had a history of hypertension. Twenty patients were female. Histopathological study demostrated the derangement of IEL and the deficiency of type III collagen were prominent in aneurysmal patients (p < 0.05). Fifty years old or older patients did not show correlation with the deficiency of type III collagen, but with the derangement of IEL (p < 0.05). The female sex was not correlated with the derangement of IEL but with the deficiency of type III collagen (p < 0.05). However, Hypertension was not correlated with these pathologic data. Conclusion : Patients with intracranial aneurysms have severe histopathologic changes of the arterial wall showing the derangement of IEL and the deficiency of type III collagen. In the clinico-pathologic study, the advanced age and female sex were considered as risk factors of the intracranial aneurysm.

Objectives This study was designed to find out influential factors associated with Hospitalization of the patients from traffic accident by Groups. Methods Based on the medical charts, we analyzed statistical study of 486 patients putting them into two groups to identify the factors associated with the duration of hospitalization involving age, sex, elapse day (Interval between time of injury and visit to hospital), and the types of accident. Patients in group A were diagnosed with a mere 'sprain', and patients in Group B had other symptoms accompanied by 'sprain'. Results 1. In group A, cervical sprain was the most and male patients with the symptom outnumbered female patients. In group B, headache was most where female patients had the symptom 1.7 times more than male patients. 2. Female patients in group B were found to stay for a longer period of time in the hospital than the male counterparts (p<0.05). 3. Both group A and B have positive correlation between length of hospital stay and age though group B exhibited stronger correlation. 4. Patients who had accident while riding bus in group A and those who were pedestrians in group B were found to stay in the hospital for a significantly longer period of time than those who had any other types of accident (p<0.05). Conclusions We noticed that hospital stay lengthened when the patients were older and when they had accidents while riding bus in Group A whereas in Group B, patients stayed longer when they were females and older as well as when they were pedestrians in accidents.

Purpose: This study aimed to investigate the characteristics of the symptoms of temporomandibular disorders (TMD) in Korean children and adolescents using representative samples and questionnaires. Methods: A survey involving the interview of 10-, 12-, and 15-year-old children and adolescents regarding the symptoms of TMD was conducted as a part of the 2010 National Oral Health Surveys. The study population included 18,112 subjects (male, 9,734; female, 8,378). The interview involved three questions related to the symptoms of TMD. The prevalence of symptoms of TMD, correlation of the symptoms with sex and age, and the difference in the number of symptoms according to sex and age were analyzed. Results: Among the symptoms of TMD in children and adolescents, the prevalence of temporomandibular joint (TMJ) sounds during mouth opening was 13.0%, while those of TMJ pain and limitation were 3.1% and 4.3%, respectively. While the prevalence of TMJ sounds during mouth opening did not show any statistically significant difference between the sexes, the rates of prevalence of TMJ pain and limitation of mouth opening in were higher in the female subjects than the male (p<0.05). It was also observed that the older the subjects, the higher the prevalence of TMJ sounds, TMJ pain, and limitation of mouth opening (p<0.05). The number of symptoms of TMD was found to be increased among female subjects as well as the older ones (p<0.05). Conclusions: There are variations in the prevalence of symptoms of TMD among Korean children and adolescents according to sex and age, which is consistent with the results of previous studies. It is necessary to conduct a national cohort study to evaluate the risk factors for TMD in children and adolescents.

The purpose of this study was to investigate the bodice prototype method suitable for the upper body shape of old-old aged women using the 3D anthropometric data. And it was to provide the basic data for the upper body garments of old-old aged women. In the overall appearance evaluation, the B pattern was rated as 4.00, and it was evaluated as the most suitable for the bodice prototype of the old-old aged woman. The E pattern was rated lower than normal, and the L pattern and the S pattern were found to be inadequate for older female bodice prototypes. As a result of the measurement of the waist and bust air gap of bodice prototype, the air gap of the bust was not significantly different between the patterns. But the waist air gap showed the largest difference between the L pattern and the S pattern. As a result of evaluating the appearance, the amount of space in the state of 3D simulation, and the air gap, the pattern B appeared to be the most appropriate prototype for the old-old aged women's body shape. However, there is a tendency that the shoulder end point is biased toward the back, so it is necessary to set the inclination of the back shoulder line to be more gentle. Conversely, the front shoulder should be more inclined. In the case of the 3D simulation, the B pattern showed that the other parts generally fit well. In the case of the 3D simulation program used in this study, it was evaluated that it is suitable only for the normal body shape because it is impossible to set the isometric angle which is one of the characteristics of the older female body shape. A study on the bodice prototype suitable for the bent body shape should be carried out through experiments on the actual body shape of various elderly women. In order to cope with the increase of elderly people who are familiar with digital, I think it is necessary to develop an avatar that reflects the old female body shape.

Background: This study aimed to investigate whether working long hours was related to infertility among female Korean workers, while taking age into consideration. Methods: We used data from the 2018 National Survey on Fertility and Family Health and Welfare in Korea that is a cross-sectional, nationally representative, and population-based survey. Infertility was defined as women who were not pregnant after regular unprotected intercourse for a year. Working long hours was classified as ≥52 hours, and subgroups as per age were classified on the basis of being younger or older than 40 years of age. Differences in infertility risk between the long working hour group and none were estimated in crude and fully adjusted logistic regression models with age-group stratification. Results: Of 5,909 Korean female workers, the crude and adjusted odds ratios (95% confidence intervals) of infertility for working long hours were 1.295 (0.948-1.737) and 1.303 (0.921-1.809), respectively. In the subgroup of patients below 40 years of age, the crude and adjusted odds ratios (95% confidence interval) were 1.957 (1.216-3.039) and 1.921 (1.144-3.120), whereas those aged 40 years or older had 0.994 (0.647-1.471) and 0.939 (0.560-1.501), respectively. The weighted prevalence of infertility increased as weekly working hours increased only for the younger than 40-year subgroup. Conclusions: Infertility is associated with working long hours, especially in young-aged workers. Thus, the working schedule must be structured to better suit young female workers.

The increase of female employees tends to change the traditional division of the roles of members in the family, and as a result it changes the idea of family relation and the extent of how housewives with job feel happy toward their marriage. Therefore, it may be very significant to study what attitude woman job holders as housewives have toward their family, especially parents-in-law. In this paper the writer has sampled as an exemplary group woman teachers who teach home economics in high schools in Seoul, and investigated what opinion they have toward the problem of living together under the same roof with their parents-in-laws and otherwise of financing them in an older age. This analysis is based upon 130 questionnaires collected as proper data out of 138. The conclusion made from the analysis is as follows : (1) as regards the living together under the same roof if necessary in the future, one-fifth of the group approves in affirmative terms ; (2) but when parents-in-law become older, about half of the teachers wish to live with them in the same home and except the indefinite few, one-third of them taken the negative position ; (3) finally, the great majority (84%) regard as their duty the financial support in any case when parents-in-law become older, and only five per cent answer in negative. This analysis leads to the further conclusion that the idea of family relations cherished by high school teachers of home economics is not yet far off the traditional relationship with the intention of gradual improvement, but on the other it still sticks to the traditional line without too much impairing it.
