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.

This study examined the effect of emotional factors, physical factors and socioeconomic factors on suicidal ideation of 75 or older seniors and sought to identify what kinds of factors should be satisfied to prevent their suicide. Using "2017 National Survey of the Elderly", the study conducted survey among 75 or older 3,023 males and 1,295 females. It used multivariate logistic regression analysis to identify the factors affecting suicidal ideation. As a result, the study found that ties with their offspring, the number of chronic diseases, being abused or not, depression and living with or without espouse had significant effects on their suicidal ideation and abuse was the largest factor. Therefore, in order to reduce suicide rate of 75 or older seniors, more active attention should be rendered to their physical, socioeconomic and emotional health problems, and measures to reduce elderly abuse should be sought. In particular, institutional improvement and revitalization of elderly counseling institutions are needed to reduce elder abuse

PURPOSE: This study aims to analyze the prevalence and risk factors of stroke in Korean older adults and provide basic data for stroke prevention. METHODS: Based on the data from the 2019-2021 Korea National Health and Nutrition Examination Survey, 5,750 adults aged 65 or older who participated in the health survey were selected. Risk factors for stroke were analyzed through complex sample multiple logistic regression analysis. RESULTS: As a result of this study, the prevalence of stroke among the subjects was 6.20%. Stroke risk factors were elderly, male, low personal income level, and current and past smoking experience. The risk of stroke prevalence was OR 1.076 (95% CI 1.048-1.104) higher with each age increase. According to gender, the risk of stroke prevalence was OR 1.587 (95% CI 1.068-2.358) higher in males compared to females. In the case of individual income level, the risk of stroke prevalence was OR 1.509 (95% CI 1.011-2.253) higher in Q1, the lowest compared to Q4, which has the highest income level, and it was not significant in Q2, and Q3. Compared to non-smokers, current smokers had an OR 1.717 (95% CI 1.087-2.712), and past smokers had an OR 1.546 (95% CI 1.095-2.183). CONCLUSION: The prevalence of stroke in Korean older adults was 6.20%, and the risk factors for stroke were old age, men, low individual income level, and smoking. Therefore, prevention programs and smoking cessation education are needed for subjects with stroke risk factors.

Tile purposes of this study were to find out any significant relations among body image, needs for body modification, self concept, and some selected clothing behaviors of two age group females using social comparison theory as the research background. The sampling method was a convenient sampling, and the subjects were 56 females aged from 20 to 24 years and 54 females aged from 40 to 49 years. The quasi-experiment and survey were conducted from May 1 to June 30, 2002. The results of tile study were as follows. First, the perceptual body image is more important than measured body size and ideal body size in body image. Apart from measurement instrument, people who perceived slim had higher self concept, exhibition and conformity of clothing. Second, there were significant differences between the two age groups(twenties and forties) in needs for plastic modification, self concepts and clothing behaviors. The younger age group exhibited higher need for modification than the older age group and the younger group also showed higher self concept, higher interests in clothing and fashion, more exhibition tendency and conformity to clothing.

This study shows trends and age-sex patterns of mortality in Korea, based on adjusted death registration data during 1956∼1980. Description on the data-the types of errors and their methods of adjustment-are presented elsewhere (Kim, 1986). Crude death rates have declined in 20 years to 7.0 in 1976∼1980, almost half the level of 13.0 in 1956∼1960. Mortality of females declined faster than males, especially at older ages. Substantial differences in provincial mortality are observed based on the expectation of life at birth. The difference between the highest and the lowest provinces is 9.2 years for males and 8.3 years for females during 1976∼1980. This study presents two interesting features of age-sex patterns of mortality in Korea. One feature is higher female mortality than males during childhood periods. However, infant mortality is higher for males than for females throughout the period, though the difference is much smaller than is expected from various model life tables. Another feature is the rapid rise in mortality for males after age 40. This pattern is found to be existed throughout the period 1956∼1980. Further studies are recommended to establish its causal linkage to traditional sex role (as main bread winner) and health behavior (smoking and drinking) of males and recent rapid industrialization in Korea.

Breast cancer (BC) is the most common malignancy of women worldwide. In the past it was considered as disease of older middle aged women, but the incidence of BC in young females is growing in recent years concordant with studies in Pakistan. In this paper, we reviewed the mutant functions of tumor suppressor genes (BRCA1, BRCA2, p53, ATM and PTEN), epigenetic transformation and involvement of estrogen receptors in development of breast cancer. We further reviewed the current situation of BC in Pakistan that depicts a higher incidence in young females. According to SKMCH and RC data, age group 45-49 years is more prone to BC with high rate of incidence 45.42%. A few studies explored the high expression of ER, PR and HER-2/neu in Pakistani females. Moreover, presence of BRCA1 (c.1961dupA) mutation in Pakistani shows concordance with data in different areas of world. But we are unable to find an authentic study that can explore epigenetic based transformation of breast tumors in Pakistan. This area of research needs more attention to explore the complete picture of BC in Pakistan.

This study was conducted to determine the relationship between the body fat percent (BF%) and body mass index (BMI) of Koreans and the differences with Caucasians. Complete data were collected from 3297 subjects (2441females and 856 males) between the ages of 18 and 79. Data were collected between September 2001 and November 2001 in Seoul and Pusan. For the statistical analysis, only the data on subjects between the ages of 18 and 65(3200) were used Body weight and height were measured BMI (kg/$m^2$) was computed From BMI, BF (%) was calculated using age- and sex-specific prediction formulas. BF% was assessed using an INBODY 2.0 body fat analyser. Data analysis showed that the females were significantly younger than the males, were smaller, lighter and had a lower body mass index. Body fat percent of the females was higher than that of the males. 1he differences between actual measured BF% and BF% as predicted from prediction equations from the literature, based on BMI, age and sex, were correlated with level of body fat and age. There is a significant age-related decrease in body fat in Koreans for any given BMI and sex, which is remarkably different compared to age-related increases in body fat in the European reference group. For the same age and BF%, Korean females have a slightly lower BMI than their European counterparts. Korean males have, for the same age and BF%, a higher BMI than their European counterparts. The differences between females and males were not significant. It was concluded that, assuming that the data on body fat percent was correct, that the relationship between BF% and BMI is quite different in Koreans than in European Caucasians. Thus, for younger Koreans cut-off values for obesity should be slightly lower than those for Caucasians whereas for older Koreans the cut-off points for obesity should be higher than those for Caucasians.

The objectives of this research were to investigate the relationship between purchase behavior and consumer dissatisfaction of cosmetics at internet shopping malls, and to examine how the purchase behavior and consumer values influence the consumer dissatisfaction. Subjects were 212 females in Seoul who had experiences of cosmetic shopping at internet shopping malls. Consumers showed highest dissatisfaction when the purchased cosmetics were different from the products showed at internet shopping malls. The dissatisfaction with consuming system was higher than buying system or transporting system. The higher the expense and frequency of cosmetic purchase, the lower the consumer dissatisfaction of buying system. Females of 18 to 24 years old purchased color cosmetics more than females of 25 to 39 years old did. Females of 25 to 39 years old purchased functional skincare products more than females of 18 to 24 years old did. The cosmetic purchase expense of older groups was higher than that of younger one. The more consumers spent time on the internet, the more frequent they bought the cosmetics at internet showing mall. Consumers were most willing to buy basic skincare products at the internet shopping mall (42.9%). The consumer dissatisfaction with cosmetics at internet shopping malls was influenced the most by the happiness value(-) and the next by the responsible value, the frequency of cosmetic purchase at internet shopping malls(-) in order.

Changes of gonadal morphology and mRNA expression patterns of vitellogenin were investigated in Siberian sturgeon Acipenser baerii (Chondrostei) during its early gonadal maturation period. Early differentiations and morphological transitions of both ovaries and testes appeared to occur actively until the age of 3 years, however from then on, the maturation patterns to full maturity were largely gender-dependent, in which males showed a faster progression of maturation than did females while females experienced a steady-state progress with a lagged interval before entering the final maturation. Expression of vitellogenin mRNAs are closely correlated with transitional patterns of gonadal appearances. In both females and males, hepatic mRNA levels of vitellogenin exponentially increased in the earliest interval (up to 1-year-old). However, in subsequent periods, vitellogenin expression in females continued to increase with age, whereas in males, the expression stabilized at a younger age. Nevertheless, at the age older than or equal to 7-year-old, fully matured individuals showed a quite low level of vitellogenin expression in both females and males. Collectively, results from this study could be useful as a fundamental guideline to address the gonad maturation of this sturgeon species, which is helpful for making practical decisions about farming practices and management for caviar production on local sturgeon farms.

The purpose of this study is to explore the factors affecting the welfare needs of the rural marriage migrant females. A survey was conducted on 300 rural marriage migration females using probability sampling and for the analysis stepwise regression was used. The major findings of this study can be summarized as follows. The welfare needs of counselling on husband' behavior problem were higher in cases of worse mental health, better physical health, younger age and lower participation in the meetings with her fellow countrymen. The welfare needs on the children raising and education were relatively higher among the migrant females from Vietnam and younger age. The needs on the job skills training were lower in cases of the migrant females from Philippines, China(the Chinese) and were higher in cases of lower level of family understanding. The welfare needs on the job placement were higher among older and lower community affinity, and were lower in cases of the migrant females from Philippines. The results suggest that the welfare services should be differently provided to the migrant females in reflection of the age, education level, nationality and community resources. Further, the mental health screening test and treatment services for migrant females are needed since the welfare needs increase when the migration females have worse mental health condition.
