The explosion of the aging population is changing the social environment of today's older people. Traditionally in Korea, a large percentage(over 90%) of elderly parents have lived with their married first son. But today, the number of elderly who live with their married sons has decreased(65.6%) The number of those who live in a different situation such as with their married daughter, unmarried offspring, with a spouse or alone has increased (34.4%) We can expect that the number of the elderly who have to live in institution will increase. The objective of this investigation was to determine differences in the number of health Complaints of older people according to their living situation with a view to planning more effective health care. The sample consisted of 231 persons over 65 years of age, 60 living in an Old Age Home ana 171 living in their own home in Kwangju. Data were gathered from July 9 to 26, 1983 by nursing students using a Questionnaire which was a modified form of the Cornell Medical Index. The data were categorized according to the subjects, living, sex, educational level, previous occupation, hobbies and sexual activity. The date were analyzed for statistical significant differences using F and X²tests. findings included the following: 1. There was a higher number of health complaints from persons who live in the institution than those living at home, but the difference was not significant. 2. The highest number of health Complaints were from persons who live alone, followed by those living with their daughters, and then by those living in the institution. Persons who live with their sons had the least Complaints. The difference in the number of Complaints accord-ing to with whom they were living was significant. 3. Women had signincantly more Complaints than men. Persons who were not living with their spouses had significantly more complaints than those living with their spouses.4. The higher eductional level the persons had, the less health Complaints they had. The number of Complaints accoraing to educational level was significantly different. 5. The highest number of health complaints were from persons who had involved in Commerce and industry, followed by those in Agriculture. Persons who were civil servant had the least 6. There were more complains from persons who had no hobby than those with hobbies. The complaints. The difference was significant. difference was significant. 7. Persons who said they were sexually inactive had significantly more complaints than those who said they were sexually active. As age increased, sexual activity significantly decreased. Those who lived with their spouse were significantly more sexually active. 8. The highest number of Somatic Complaints were eye fatigue, followed by nocturnal frequency, lumbago, cramps in extremities, vertigo, stiffness in Shoulder, tinnitus, common cold and constipation. The order of Psychic Complaints from higher to lower were anger. sensitivity, anxiety, depression and loneliness. 9. This group of Elderly persons said they valued Health the most, followed by Harmony, Religion, Money and Honor.

Recently, human life and the low birth rate and aging population has increased exponentially. Entry into an aged society in the present case and the different policy alternatives, and is a reality. Resolution of one of these older active community participation and production activities to foster a rich life, infants need to be able to build a ubiquitous environment can be damaging. Latest IT technology in the development of intelligent life on all human life even more convenient by combining the computer and try to build a productive environment is. You simply connect your computer to the elderly rather than older users to use, efficient and productive way to improve efforts to follow. Emerging as an alternative to the more efficient interfaces for ubiquitous computing, user interface design criteria, albeit a little uncomfortable by suggesting improvements of the elderly and their participation in production activities helped to improve the quality of life. Ubiquitous environment, as well as means to improve the living environment of older people live independent lives, as given us is that you can get the premise of this study was in progress.Thus, by analyzing the characteristics of the elderly for the elderly by offering more efficient way to interface design for a new era of ubiquitous pushing back the boundaries of the elderly have been instruments to achieve social vitality.

Osteoarthritis (OA) is the most common degenerative joint disorder in the elderly population. To identify OA-associated genetic variants and candidate genes, we conducted a genome-wide association study (GWAS). A total 3,793 samples (476 cases: wrist + knee and 3317 controls) from a community-based epidemiological study were genotyped using the Affymetrix SNP 5.0. An intronic SNP (rs4789934) in the TIMP2 (tissue inhibitor of metalloproteinase-2) showed the most significance with OA (odd ratio [OR] = 2.06, 95% confidence interval [CI] = 1.52-2.81, p = $4.01{\times}10^{-6}$). Furthermore, a poly-morphism (rs1352677) in the NKAIN2 ($Na^+/K^+$ transporting ATPase interacting 2) was suggestively associated with OA (OR = 1.43, CI = 1.22-1.66, p = $7.01{\times}10^{-6}$). The present study provides new insights into the identification of genetic predisposing factors for OA.

WIn Korea, the rapid rise of elderly population and dementia prevalence resulting from the unprecedently rapid aging in the world is being emerged as a serious social issue. Caring the elderly with dementia is a different way from a general life and is a world which new cultural existential relationships are interlaced from the relationship viewpoint. From this aspect, the psychological matter of family caring a demented elderly needs to be studied for existential understanding in depth and fundamentally. This study focused on in-depth understanding and description of the stress phenomena experienced by family caregivers with a demented elderly based on Giorgi's method among phenomenological research methods and using existential group counseling techniques. Total 8 sessions of existential group counseling were conducted. This study drew out the outcomes(emotional stress, psychosocial stress, time-dependent stress) of participants' self-awareness experiences by applying 4 steps of Giorgi's phenomenological research methodology based on the Existential Philosophy to participant's intensive statements about stress of family caring a demented elderly drawn out of the existential group counselling sessions. It is hoped that understanding the pain of the supporters who cannot express their own pains through the research results and their self-help group counseling activities will become active, contributing to the health of our society which is about to enter post-aged society.

Purpose: Elderly people are thought to be more susceptible to periodontal disease due to reduced immune function associated with aging. However, little information is available on the nature of immune responses against putative periodontal pathogens in geriatric patients. The purpose of this study was to evaluate the serum IgG antibody responses to six periodontal pathogens in geriatric subjects. Methods: The study population consisted of 85 geriatric patients and was divided into three groups: 29 mild (MCP), 27 moderate (MoCP), and 29 severe (SCP) chronic periodontitis patients. Serum levels of IgG antibody to Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, and Prevotella intermedia were measured by enzyme-linked immunosorbent assay (ELISA) and compared among the groups. Results: All three groups showed levels of serum IgG in response to P. gingivalis, A. actinomycetemcomitans, and P. intermedia that were three to four times higher than levels of IgG to T. forsythia, T. denticola, and F. nucleatum. There were no significant differences among all three groups in IgG response to P. gingivalis (P=0.065), T. forsythia (P=0.057), T. denticola (P=0.1), and P. intermedia (P=0.167), although the IgG levels tended to be higher in patients with SCP than in those with MCP or MoCP (with the exception of those for P. intermedia). In contrast, there were significant differences among the groups in IgG levels in response to F. nucleatum (P=0.001) and A. actinomycetemcomitans (P=0.003). IgG levels to A. actinomycetemcomitans were higher in patients with MCP than in those with MoCP or SCP. Conclusions: When IgG levels were compared among three periodontal disease groups, only IgG levels to F. nucleatum significantly increased with the severity of disease. On the contrary, IgG levels to A. actinomycetemcomitans decreased significantly in patients with SCP compared to those with MCP. There were no significant differences in the IgG levels for P. gingivalis, T. forsythia, T. denticola, and P. intermedia among geriatric patients with chronic periodontitis.

The purpose of this study was to measure the thickness of masticatory mucosa in the hard palate as a donor site for mucogingival surgery by using computerized tomography(CT), Thickness measurements were performed in 84 adult patients who took CT on maxilla for implant surgery and 24 standard measurement points were defined in the hard palate according to the gingival margin and mid palatal suture. Radiographic measurements were utilized after calibration for standardization. Data were analyzed to determine the differences in mucosal thickness by gender, age, tooth positions and depth of palatal vault. The results of this study were as follows: 1. Mean thickness of palatal masticatory mucosa was $3.93{\pm}0.6mm$ and females had significantly thinner mean masticatory mucosa($3.76{\pm}0.56mm$) than males($4.04{\pm}0.6mm$)(p<0.05). 2. The thickness of palatal masticatory mucosa increased by aging. 3. Depending on position, masticatory mucosa thickness increased from canine to premeolar, but decreased at the first molar, and increased again in the second molar region(p<0.0001). 4. No significant difference in mean thickness of palatal masticatory mucosa were indentified between low palatal vault group and high palatal vault group(p>0.05). The results suggest that canine and premolar area appears to be the most appropriate donor site for soft tissue grafting procedure. The measurement of the thickness of palatal masticatory mucosa by using computerized tomography can offer useful information clinically but further studies in as-sessing the validity and reliability of the method using computerized tomography is needed.

Japanese agriculture has faced to several threats: aging and decrease of farmer population, global competition, and the risk of climate change as well as harsh and variable weather. On the other hands, the number of large scale farms is increasing, because farm lands have been being aggregated to fewer numbers of farms. Cost cutting, development of efficient ways to manage complicatedly scattered farm lands, maintaining yield and quality under variable weather conditions, are required to adapt to changing environments. Information and communications technology (ICT) would contribute to solve such problems and to create innovative technologies. Thus we have been developing an early warning and decision support system to reduce weather and climate risks for rice, wheat and soybean production in Japan. The concept and prototype of the system will be shown. The system consists of a weather data system (Agro-Meteorological Grid Square Data System, AMGSDS), decision support contents where information is automatically created by crop models and delivers information to users via internet. AMGSDS combines JMA's Automated Meteorological Data Acquisition System (AMeDAS) data, numerical weather forecast data and normal values, for all of Japan with about 1km Grid Square throughout years. Our climate-smart system provides information on the prediction of crop phenology, created with weather forecast data and crop phenology models, as an important function. The system also makes recommendations for crop management, such as nitrogen-topdressing, suitable harvest time, water control, pesticide spray. We are also developing methods to perform risk analysis on weather-related damage to crop production. For example, we have developed an algorism to determine the best transplanting date in rice under a given environment, using the results of multi-year simulation, in order to answer the question "when is the best transplanting date to minimize yield loss, to avoid low temperature damage and to avoid high temperature damage?".

Leaf senescence is the process of aging in plants. Chlorophyll degradation during leaf senescence has the important role translocating nutrients from leaves to storage organs. The functional stay-green with slow leaf yellowing and photosynthesis activity maintenance has been considered one of strategy for increasing crop productivity. Here, we have identified two QTLs on chromosome 9 and 10 for leaf senescence with chlorophyll content of RIL population derived from a cross between Hanareum 2, early leaf senescence Indica-type variety, and Unkwang, delayed leaf senescence Japonica variety. Among these QTLs, we chose qPLS1 QTL on chromosome 9 for further study. qPLS1 was found to explain 14.4% of the total phenotypic variation with 11.2 of LOD score. Through fine-mapping approach, qPLS1 QTL locus was narrowed down to about 25kb in the marker interval between In/del-4-7-9 and In/del-5-9-4. There are 3 genes existed within 25kb of qPLS1 locus: LOC_Os09g36200, LOC_Os09g36210, and LOC_Os09g36220. Among these genes, transcript level of LOC_Os09g36200 was increased during the leaf senescence stage and the expression level of LOC_Os09g36200 in Indica was higher than in Japonica. Finally, we chose LOC_Os09g36200 as candidate gene and renamed it as OsPLS1-In and OsPLS1-Jp from Indica- and Japonica-type rice, respectively. OsPLS1-In and OsPLS1-Jp overexpressing transgenic plants showed both early leaf senescence phenotype. These results indicate that OsPLS1 functions in chlorophyll degradation and the difference of expression level of OsPLS1 cause the difference of leaf senescence between Indica and Japonica in rice.

Background: Korea shows rapid population aging and increase in healthcare service use and expenditure. Also, this would be accelerated because of the baby boomers who will be 65 years old and more in 2020. Chronic disease is another reason that increases the use of healthcare service and expenditure of the middle- and old-aged households. Catastrophic health expenditure (CHE) is the index which can indicate the households' burden of health spending. Despite the importance, there are few studies on CHE of middle- and old-aged households and especially no panel study yet. This is the reason that this study is carried out. Methods: This study used 3-year data from the Korea Welfare Panel Study conducted from 2009 to 2011. We defined CHE if a household's health expenditure is equal or greater than the threshold value if income remaining after subsistence needs has been met. We used 4 different threshold values which are 10%, 20%, 30%, and 40%. In order to look at the households which experienced CHE, we conducted panel logit analysis after correspondence analysis and conditional transition probability analysis. Results: This study showed three notable results. First, there has been a difference among age groups, which implies that the older people are, the more easily they can experience CHE. Second, the households with no private insurance are shown to have a higher CHE occurrence rate. Lastly, there has been a significant difference among the kinds of chronic diseases. The households which have cancer, cerebrovascular disease, and heart disease have a higher CHE occurrence rate. However, the households with diabetes have no significant effects to CHE occurrence. Also, hypertension has a negative effect to the occurrence. Conclusion: With the results, it can be implied that elderly people with chronic disease are more needed in medical coverage and healthcare. Also, private insurance can play its role in protecting households from CHE. Therefore, it needs to conduct studies on CHE especially about different age groups, private insurance, and chronic disease.

The ratio of the elderly population is rapidly growing due to socio-economic development and better medical services. As the average life-span of the Korean elderly becomes longer, the proportion of the elderly is increasing. Therefore, the elderly need to sustain a high quality of life. However, all these factors, such as sensory loss, decreased endurance, mobility limitation, and a loss of independence, act to diminish the quality of life among the elderly. It is necessary for elders to adapt themselves to aging, to maintain their physical functions and especially, it is important to keep their independence in activity of daily living and self care. Therefore, this study was designed to identify the degree of activity in daily living and exercise of a self-care agency and to investigate the relationship between activity of daily living and self-care agency. Also, this research aimed to contribute to nursing interventions that maintain and promote quality of life of the elderly and to enable themselves to live independently. The subject of this study were 160 elders, over age 65, who were sampled in C city. Data were collected by observation and questionnaires from May,1999 to December, 1999. The measurement tools were Barthel Index(1979), Lawton & Brody(1969) for activity of daily living and Kearney & Fleischer(1979) for self-care agency. Data were analyzed by SAS PC+ package and included descriptive analysis, t-test, ANOVA, Pearson correlation coefficient, and Cronbach's alpha. The conclusions of this study are summarized as follows; 1. The mean of ADL and IADL was 96.09 and 16.38, respectively. The score described activity of daily living among the elders in C province as moderate. Particularly, in the items of IADL, the item of medication was the highest score. 2. The mean for exercise of self-care agency was 76.48, a moderate degree. 3. The degree of ADL and IADL according to demographic characteristics was significantly different statistically in pocket money, the presence of disease, perceived health status and in occupation, pocket money, family type, the presence of disease, and perceived health status, respectively. 4. The dagree of selt-care agency according to demographic characteristics was significantly different statistically in gender, education level, economic status, and pocket money. 5. There was a significant positive correlation between activity in daily living and self-care agency. Based on these results, further research is suggested to discover the variables influencing the activity of daily living and self-care agency to develop nursing strategies for improving self-care and activity of daily living among the elderly.
