The aging of population stems from the decline of birth and death rates. A sudden aging society results in a variety of social issues like the poverty, role loss, alienation, health problems, etc. of the elderly. What counts in solving these issue is to make good use of the leisure time of the elderly. Leisure activities in the elderly help maintain and improve their mental and physical health, and have a great influence on improving the quality of life in the elderly. In addition, they contribute to building up a healthy social structure by forming a social intimacy. Despite these positive aspects of leisure activities, however, multiple factors prevent the leisure activities of the elderly from being actively pursued. In this respect, since there is a need to take a look at how the varied leisure activities of the elderly expose themselves in different regions, this study made an investigation so as to see what characteristics and differences each region has in the leisure activities of the elderly 65 or above. As a result, the following facts were found out: the elderly in Seoul enjoy a relatively wide range of leisure activities compared with other regions; the elderly in Gwangju spend their time mainly at home: and the elderly in the Goheung region take part in leisure activities aimed at promoting friendship. It was also revealed that there are differences among different regions in the areas of leisure activities, including the types of participation in leisure activities, the types of leisure activities at and out of home, the purpose and satisfaction of leisure activities and the frequency of domestic trips.

In this study, the potential anti-aging properties of Prunella vulgaris extract were investigated. According to our results, Prunella vulgaris extract increased collagen synthesis(74.7% at 250 ${\mu}g/mL$) and decreased on MMP-1 synthesis(90.2% at 200 ${\mu}g/mL$) and elastase activity(43.7% at 2.0%). Furthermore, it also showed free radical scavenging activity(76.9% at 2.0%) and reduced $H_2O_2$-induced cytoxicity(49.9% at 2.0%). A double-blind clinical study to investigate the effect of Prunella vulgaris extract on the skin's surface was conducted with 22 healthy volunteers, aged 34 to 48 years. The volunteers applied a cream formula with 4.0% of Prunella vulgaris extract, or placebo cream, on each crow's feet twice a day for 12 weeks. Skin wrinkles were evaluated with the naked eye and instrumental image analysis of silicone replicas, followed by statistical analysis. Twelve weeks after application of cream formula with 4.0% of Prunella vulgaris extract, we found significant improvement of facial wrinkle. Moreover, silicone replica analysis confirmed notable improvement in average of R2 and R3 at 12 weeks(p<0.05). These results demonstrate that Prunella vulgaris provides a remarkable and significant tensor and anti-wrinkle effect on the skin, which could be of great use in anti-aging skin care products.
For knowing the effects of aging on conversational skills in daily communication, this paper studied for the conversational turn-taking skills, working memory and naming ability on healthy elderly adults over 65 ages. 85 elderly adults participated in this study, which divided into four groups by ages. Speech samples were collected in natural conversation. Memorization of numbers, mental calculation, repetition of words were administered for working memory test. K-BNT was used for the naming ability. One-way ANOVA analysis was used for the comparison of conversational turn-taking skills among four groups. We analyzed the correlation between conversational skills, working memory and naming ability. The results were as follows: first, there were a significant difference in conversational turn-taking skills by age, but not by gender. There was a significant difference in 'Turn-Taking Frequency' and 'Total Utterance Frequency' among four groups. The same results were shown in the scores of females within three groups(exclude groups over 85D)(p<.01). Second, there was a significant correlation between 'rates of maintenance' and 'naming ability'. In addition, it was found that the naming test predicted 'rates of maintenance' skills. The results of this study suggest that word-retrieval ability will be helpful to enhance functional communication skills in aging old adults.
This study was undertaken to develop web-based nutrition information contents for the older adults. Twenty six domestic web-sites were analyzed and then 12 foreign web-sites and 4 education materials for the elderly of foreign university were benchmarked. Also a lot of literatures on elderly education program were reviewed. A card-sorting task was performed with 8 older adults to ascertain how the target audience organized information about nutrition. The results were as fellows. Among 26 domestic web-sites, 2 sites(7.7%) were only for the elderly. Main topics of information contents for the elderly included 'Importance of Healthy Eating', 'DRI', 'Dietary Guidelines'. Four of twelve foreign web-sites were for the elderly nutrition education. Topics of 'Dietary Guideline', 'Meal Program' were found in 4 sites and 'Importance of Healthy Eating', 'Diet & Disease', 'DRI, 'Food Guide Pyramid', 'Nutrition Fact Labels' were found in 3 sites. Education materials of foreign university dealt with basic information on 'nutrient needs changes related with aging', 'Heart & Bone Healthy Eating Plan', 'Food Guide Pyramid'. Also topics on 'Eating on a budget', 'Eating Out Guideline' were included for practical use for the elderly. Based on card-sorting process, contents framework for web-site was developed and 4 main menus for framework were respectively named as 'Nutrition', 'Meals', 'Foods'. 'Check up Nutritional Health' by panel discussion. Finally we developed nutrition information contents for 4 main menus. We focused on helping older adults recognize the importance of healthy eating and apply the nutrition information to practical use. We expect that the developed framework of contents can be a guideline for indentifying the information needs of older adults in developing effective nutrition intervention program. And we suggest that the survey for target people should be peformed for the web-site to be user-friendly designed and the developed contents be evaluated and revised in the near future.
Endometriosis is the abnormal growth of endometrial cells outside the uterus, causing pelvic pain and infertility. Furthermore, adhesion of endometrial tissue fragments to pelvic mesothelium is required for the initial step of endometriosis formation outside uterus. $TGF-{\beta}1$ and adhesion molecules importantly function for adhesion of endometrial tissue fragments to mesothelium outside uterus. However, the function of $TGF-{\beta}1$ on the regulation of adhesion molecule expression for adhesion of endometrial tissue fragments to mesothelium has not been fully elucidated. Interestingly, transforming growth factor ${\beta}1$ ($TGF-{\beta}1$) expression was higher in endometriotic epithelial cells than in normal endometrial cells. The adhesion efficiency of endometriotic epithelial cells to mesothelial cells was also higher than that of normal endometrial cells. Moreover, $TGF-{\beta}1$ directly induced the adhesion of endometrial cells to mesothelial cells through the regulation of integrin of ${\alpha}V$, ${\alpha}6$, ${\beta}1$, and ${\beta}4$ via the activation of the $TGF-{\beta}1/TGF-{\beta}RI/Smad2$ signaling pathway. Conversely, the adhesion of $TGF-{\beta}1-stimulated$ endometrial cells to mesothelial cells was clearly reduced following treatment with neutralizing antibodies against specific $TGF-{\beta}1-mediated$ integrins ${\alpha}V$, ${\beta}1$, and ${\beta}4$ on the endometrial cell membrane. Taken together, these results suggest that $TGF-{\beta}1$ may act to promote the initiation of endometriosis by enhancing integrin-mediated cell-cell adhesion.
Background: The aim of this systematic review was to study the relationship between exposure to nitrogen dioxide ($NO_2$) in the ambient air and breast cancer incidence. Materials and Methods: A systematic review was performed based on the MOOSE guideline for review of observational studies. We searched five online databases (PubMed, Science Direct, Google Scholar, EBSCO, and Scopus) from their conception to June 2014. A pooled estimate of the correlation between $NO_2$ exposure and breast cancer incidence was calculated using Pearson's correlation coefficient. Results: A total of 654 titles were retrieved in the initial search of the databases. Further refinement and screening of the retrieved studies produced a total of five studies from four countries. The studies included three ecological studies (aggregate level) and two individual based studies (one prospective cohort and the other one a case-control study). The ecological studies were pooled and the meta-analysis of correlation coefficient without z transformation showed a pooled estimate of r = 0.89 with 95% CI of 0.84 to 0.95. Using z transformation, the pooled r was 1.38 with 95%CI of 1.11 to 1.59. No significant heterogeneity between studies was observed. Following a sensitivity analysis and the removal of each study from pooled analysis we did not see any significant change in the pooled estimate. Conclusions: It was concluded that there is a tendency toward a weak association between exposure to $NO_2$ in ambient air and breast cancer at the individual level and a significant association at the aggregate level.

This research contains awareness of antioxidant and intakes of antioxidant foods for the present evaluate college students in Seoul, 375 patients were investigated. The subjects, the woman college student more than male's responded, showed a uniform distribution in the allowance, grade and the most type of residence is living apart from their family. All male and female college students recognize a lot about health, but male college students had higher than female students interested in the health, on the other hand, female college students had higher than male college students for the health efforts for the promotion of a healthy. Awareness about the oxide and active oxygen is moderate level, but knowledge about active oxygen is low level, they responded that active oxygen was caused when received stress or do strenuous exercise. General Health Functional Foods recognized that the usual intake, but intake of antioxidant was when the activity was caused by active oxygen. They recognized that the antioxidant effect is anti-aging and vitamin, wine and tea, were perceived as antioxidant foods, are popularly known. Usually, people was initially recognized through the internet in university or high school, they desire to obtain information was high but the effort to gain understanding and knowledge about antioxidant are relatively low. The result of comparing the difference of natural antioxidant foods and antioxidant healthy functional foods, recognizes of effects and absorption rate are similar, but recognizes that natural food intake is better recognition in the economics and health functional food is better recognition in the easy intake and nature foods was more preferred than functional foods because of nature friendly. Trying to intake of antioxidant foods is low, but people is expected anti-aging and fatigue recovery through the intake of antioxidant food. People think that intake is irrelevant to the season, but summer is higher than other seasons. Showed that efficacy perceptions about health supplements are higher, but efficacy perceptions about antioxidant health supplements when ingested are at a moderate level, which is lower, due to low antioxidant for understanding. Antioxidant functional health food intake will be affected the gifts or the people around them and purchase is also more influenced by surround people than themselves. So showed that most college students prefer natural antioxidant foods than antioxidant health supplements, in case of ingested antioxidant health supplements also showed that it was consumed by surround people than personal will.
The purpose of this study is to examine which factors determine self-rated health(SRH) among Korean elderly focusing on gender differences. To achieve this purpose, it uses the Hallym Longitudinal Study of Aging, wave 4 in 2009. Participants aged 65 and over from wave 4 were selected(N=986, male 407, female 579). From wave 4, all variables were selected except for respondents' education which was from wave1. In analyses, $x^2$ or t-test were conducted to examine whether independent variables significantly differ by SRH. Then, since a dependent variable consisted of two categories-being healthy or not being healthy, logistic regressions were run. What makes gender differences in the link of independent variables to SRH were 75-84 age group, education, and IADLs. For females, 75-84 age group rated their health as worse compared to 65-74 age group, but this age group did not have significant effect on SRH for males. Females graduating from junior high school were more likely to higher rate their health compared to their counterparts. However, education was not significant for males. Instrumental activities of daily living(IADLs) is one of variables affecting SRH by making gender differences. Female having problems with IADLs were more likely to be significantly negatively rate their health compared to males. Through focusing on age, education, IADLs making gender difference in evaluating health, governments needs to support males and females differently.
It is important to maintain a healthy dietary habit to enjoy better health and quality of life in later life. However, taking care of one's dietary lifestyle at an older age may be a challenge. Especially, community dwelling low-income older adults are one of the most vulnerable population in regards to holding a well balanced healthy diet. The purpose of this research is to identify the current status of food delivery services for low-income older adults and explore related issues. In order to achieve the aim, this study conduced two sets of focus group interviews with 8 nutritionists and 7 social workers in Seoul. According to the research results, there are issues related to meals on wheels such as vague eligibility, poor operation conditions, work overload, and difficulty in realizing customized meal delivery. Food security for low-income older adults is a prerequisite for aging in place. It is necessary to discuss the ways to create favorable operating conditions to deliver customized meals and manage nutrition and hygiene from the perspective of social work.

Objectives : Parkinson's disease (PD) is the second most common neurodegenerative disorder worldwide and is characterized by the loss of the dopaminergic neurons in the substantia nigra (SN). In a previous in vitro study, we demonstrated that Sihogyeji-tang (SG), Sihosogan-tang (SS), and Sihocheonggan-tang (SC) have the potential to be candidate medicines for PD. This study aimed to compare the neuroprotective effect of SG, SS, and SC using 1-methyl-4-phenyl-1,2,3,6-tetrahydrophridine (MPTP)-induced PD mouse model. Methods : Eight-week-old male C57BL/6 mice were intraperitoneally administered with 30 mg/kg of MPTP for 5 days and orally administered SG, SS and SC for 12 days from the first MPTP injection. Motor function was assessed using the pole test and the rotarod test. Dopaminergic neuronal survival in the SN and striatum was evaluated through tyrosine-hydroxylase immunohistochemistry. Results : MPTP administration resulted in behavioral impairment and dopaminergic neuronal death in the SN and striatum. In the pole test, treatment with SG, SS, and SC alleviated the MPTP-induced motor dysfunction on day 5 and 12. In the rotarod test, SS and SG alleviated the MPTP-induced motor dysfunction on day 5, while only SS showed improvement on day 12. SS and SG significantly protected dopaminergic neurons in the SN from MPTP toxicity, and all three compounds (SG, SS, and SC) showed significant protection in the striatum. Notably, SS demonstrated superior efficacy in suppressing MPTP-induced motor dysfunction and dopaminergic neuronal death compared to SG and SC. Conclusions : These findings suggest that SS is the most effective formula among SG, SS, and SC for PD, indicating its potential role in the treatment of PD.
