Purpose: To investigate the instrumental activities of daily living (IADL), leg muscle strength, cognitive and visual functions according to the participants' demographic characters and experiences of falling in Korean elder who are residents in the community. Method: Data were collected from 351 participants aged 65 or more, who were ambulatory, A structured questionnaire and several physical function measurements were used to collect the data which were analyzed using the SAS program. Results: The participants' IADL scores were significantly different according to their age, educational level and living situation. The leg muscle strength of the elders were significantly different according to gender and age, and were also related the risk of falling. Cognitive scores were significantly different according to gender, age, education level and marital status. Visual acuity and depth perception were significantly different according to age, education level, and marital status. Conclusion: Demographic variables and experience of falling were identified as variables related to IADL, leg muscle strength, cognitive and visual function of elders. Further study with a larger and nation-wide sample is needed to identify the variables related to the physical and cognitive functions of elders.

Direct cell-cell communication via the transfer of small molecules between neighboring cells in tissue is accomplished by gap junctions composed of various connexins (Cxs). Proper postnatal development of the epididymis is important for acquisition of male reproduction. The epididymal epithelium is composed of several cell types, and some of these cells are connected by gap junctions. The present study was conducted to determine the presence of Cx transcripts in the corpus and cauda epididymis. In addition, transcriptional changes of Cxs expressed during different postnatal stages were examined by real-time PCR analysis. In both epididymal regions, the same nine Cx transcripts of thirteen Cxs tested were detected. In the corpus epididymis, the highest levels of Cxs31.1 and 37 transcripts were observed at 45 days of age, and amounts of Cxs26, 30.3, and 32 transcripts increased with age and subsequently decreased in the elderly. Expression of Cx31 was greatly increased in the adult and elder stages, while Cxs40, 43, and 45 were abundant in the early postnatal stages. In the cauda epididymis, expression of Cxs26, 30.3, 31.1, 37, and 40 reached the highest levels at 5 months of age. The levels of Cxs31 and 32 mRNAs fluctuated throughout the postnatal period. The amounts of Cxs43 and 45 transcripts were more abundant during the late neonatal and prepubertal ages than later ages. These findings suggest that regional specification of the epididymis is partly regulated by differential expression of Cx genes during the postnatal developmental period.

Helicobacter pylori (H. pylori) is an important bacterial pathogen that causes chronic gastritisand is associated with gastroduodenal ulcer disease, adenocarcinoma of the distal stomach, and gastricH. pylori infection associated with host agehave not been well-defined in human. To evaluate the difference in host susceptibility to infection in relationto age of acquisition of H. pylori infection, we designed an experiment involving inoculation of H. pyloriATC 43504 at different ages of Mongolian gerbils. H. pylori was inoculated at 5 weeks and 18 monthsof age, as representatives of early and late infection, respectively. Animals were sacrificed 1 week and 4weeks after challenge, and the stomach was removed from each animal for bacterial culture, histologicalexamination, and polymerase chain reaction test. 5 week-old gerbils revealed infection andmaintained continuously its infection until 4 weeks. However, old gerbils did not maintained H. pyloriinfection. These data suggest the insusceptibility of H. pylori in old Mongolian gerbils and the importanceof animal ages for successful animal experimental infection. Also, the results demonstrated that earlyinfection of H. pylori increases its host susceptibility, as compared to the case with later infection, possiblybecause of differences in host gastric mucosal factors and imunologic responses.

The purpose of this study was to analyze the differences in make-up behavior according to clothing involvement, age, and face satisfaction. Subjects of is study were the females in Seoul and Kyonggi, who were 20s and 40 $.$ 50s. Questionnaire was used as major method of gathering data. The data were collected from Sep. to Oct. in 2003 and analyzed by using SPSS 10.0 with various techniques such as the factor analysis, mean, percentage, cluster analysis, ANOVA, Duncan test, 1-test, Cronbach＇s $\alpha$, and $\chi$$^2$-test. The results of this study were as follows: 1. The consumers were classified into four categories by clothing involvement; high clothing involvement group, low fashion involvement group, middle clothing involvement group, low clothing involvement group. 2. The differences in make-up behavior according to the clothing involvement showed that make-up behavior was getting more aggressive as clothing involvement was getting higher. And generally Korean females thought the make-up was important. 3. The differences in make-up behavior according to the age revealed that 20s＇ make-up behavior was fashion oriented more than 40ㆍ50s, and 40ㆍ50s＇ make-up behavior was that they were taking a serious viewer than 20s＇ in interpersonal relationship oriented make-up behavior. 4. The result of differences in make-up behavior according to the face satisfaction was that no noticeable difference was found depending on the face satisfaction. This study revealed that the differences in make-up behavior according to clothing involvement and age were found and suggested that the cosmetic market segmentation could depend on clothing involvement market and two age group market such as younger and elder than 40ㆍ50s.

This study was conducted to compare the nutritional status, nutrient intakes, and chronic disease risks of Chinese elderly people. MNA (Mini Nutritional Assessment) developed for elderly people was used to determine their nutritional status. In this study, participants consisted of 148 urban residents aged 65 years and over residing in three cities in Shandong Province, China. Participants were 67 (45.3%) men and 81 (54.7%) women, and average age was 72.8 years. According to MNA score, 77.7% of participants were 'well nourished', 22.3% were 'at risk of malnutrition', and 2% were 'malnourished'. Nutritional status was divided into two groups by MNA score as 'well nourished' and 'malnourished', which was formed with the combination of 'at risk of malnutrition' and 'malnourished'. Compared with the well nourished group, the malnourished group was older, and physical status indicators such as weight, BMI (Body Mass Index), and calf circumference of the malnourished group were much smaller. The malnourished group had higher prevalence rates of heart disease and stomach disorders while the well nourished group had a higher rate of hypertension. There was no significant difference between the malnourished group and well nourished group in nutritional intake below Chinese DRIs (Dietary Reference Intakes) among elder males. A higher proportion of elder females showed insufficient intakes of energy, protein, vitamin A, vitamin E, and zinc in the malnourished group compared to the well nourished group. The INQ (Index of Nutrition Quality) of calcium, magnesium, zinc, iodine, and most vitamins was less than 1 in both the malnourished and well nourished groups.

As an aging population has increased vastly and nuclear families have been a dominating family type in modern Korean society, the numbers of the elderly who suffer Empty Nest Syndrome and LID (Loss Isolation Depression) syndrome have been accelerated. These syndromes involve psychological instability, melancholy, and lethargy. To make the elderly get out of this phenomenon and live actively, the scheme of converting their existing house into shared housing was set as a hypothetical solution in this study. This study sets out to find out responses of the elderly to alter their own house's function in housing improvement area. A Small Workshop Panel method was used and the elderly aged 55 years upwards took part and they own a detached house in a housing improvement area that is relatively large for the elderly or the elderly couple to live alone. Through the workshop, problems that the elderly have been experiencing within their houses were looked into and responses of the elderly on altering their house to shared housing by introducing developed schematic plans. Although, the first response was negative, positive responses from the house owners were carried out when a visual support i.e. developed shared housing plan was provided. The positive response was based on the fact that subsidies from the government on house renovation and tenants matching programs are supported as shared housing could provide home owners economical support with rents and help them to feel less lonely. This is a way of relieving the elderly from being neglected and supporting them to live and age actively in their later lives. Furthermore, by providing a visual media to the elder residents in housing improvement area, their greater understandings on the development and addressing their opinions were possible. Therefore, more tools that promote elder residents' participation are needed for future housing improvement projects and an aging society.

The graying of population is not only a significant problem in developing countries, but also in a small country which is passing industrialization and urbanization. Industrialization and urbanization has raised a number of nuclear family. Moreover, changes in the environment and development in science such as a medical development and improving standard of health and hygiene have raised an average life expectancy. Considering these factors, average age of population is going up continue. Developed countries such as Europe, US and Japan have already experienced the graying and some countries have entered aged society. Korea is expected to be reached post-aged society in 7 years which is faster than developed countries that started aging society earlier than Korea. The purpose of this study is a analysis of resident's opinions and preference and using space of elders facilities and seeking a plan to construct the facilities through suggesting standard of use space. Firstly, this report will classify current situation of spacial organization on elder facilities focusing on major sectors and will compare in size. Moreover, standard of area distribution through an analyzing characteristics of each spacial organization. Secondly, The report will compare and analyze between space and main traffic line through classifying traffic lines between staffs and residents of elder facilities and understanding characteristics and problems of each traffic line. Lastly, this will study perception and preference on staffs at elders facilities and middle old aged people who are potential demander, and compare between these people.

French poststructuralists Gilles Deleuze and Felix Guattari pointed out that the minority age already has come in the modern society through discussing minority topic. Futhermore, they supported 'Becoming' as new methodology that minorities escape from suppressed reality. 'Becoming' is the practical concept for how one identity could split into different lives and subjects, thus it could be explained as an exemplary that autonomous change and actively entering into different lives. The purpose of this study seeks the practical way for elder women can independently participate in media education which is based on concretely 'becoming woman'. For this, the article examines the main concept and thought of Deleuze and Guattari. The reason why this article premises this theory is for changing 'desire' of elder women's approach to 'becoming women' through new interpretation about minority and minorities which were defined by quantitative criteria. Consequently, this article would suggests the direction of senior media education for seniors for the positive and specific effect.

Maintenance of adequate telomere length in developing cells is the most important concern to preserve the integrity of the genome. The length of telomere is strictly regulated by numerous telomere-binding proteins and/or interacting factors. Even though the expression of telomerase in the male reproductive tract has been characterized, developmental expressional profiling of telomerase and other telomere-associated proteins has not been determined in detail. The present study was attempted to examine expression patterns of catalytic subunit (Tert) and RNA component (Terc) of telomerase and two telomerase associated factors, telomerase associated protein 1 (Tep1) and TERF1 (TRF1) interacting nuclear factor 2 (Tinf2) in the testis and seminal vesicle of male rat during postnatal development. The real-time PCR analysis was utilized to quantify mRNA expression of molecules. The abundance of Tep1 mRNA in the testis and seminal vesicle was the highest at 5 months of age. Expressional fluctuation of Tinf2 during postnatal development was found in the testis, while expression of Tinf2 in the seminal vesicle was gradually increased until 5 months of age and then significantly decreased later. mRNA level of Tert gene in the testis was significantly increased at the adult and the elder, while the highest expression of Tert gene in the seminal vesicle was found at 5 months of age. Expression of Terc transcript in the testis and seminal vesicle was the highest at 5 months of age, followed by significant reduction at 1 and 2 years of ages. Such differential gene expression of telomere-associated factors and telomerase components in different male reproductive tissues during postnatal development indicates that maintenance of telomere length would be regulated in tissue- and/or age-specific manners.

Objective: This study aims to analyze the relationship between employment status and the prevalence of chronic obstructive pulmonary disease (COPD) for manufacturing and construction workers. Methods: Subjects, who had or have worked as temporary workers in manufacturing or construction worksites for the longest career years, were extracted from the KNHANES(2007-2009) database. Characteristics of demographical, socio-economic, and smoking history were treated as independent variables. Considering that smoking experience and age are significantly influential in the prevalence of COPD, logistic regressions were analyzed after stratifying subjects according to their smoking experience and age. A two-stage stratified systematic sampling method was applied for the logistic regression analysis. Results: Age, gender, and household income level were associated with the prevalence of COPD in both smoking and non-smoking groups. However, employment status was only significant among smoking group. Smoking experience and age were significantly related to the prevalence of COPD among all age groups. In addition, employment status and household income level were also associated with the prevalence of COPD in young aged group. But gender was the only significant factor among the elder group. Conclusions: This study confirmed that employment status was a major social factor which may be related to the prevalence of COPD. Proper supports such as providing safety measures should be provided to temporary workers to manage their respiratory health.
