The purpose of this study was to identify the conditions of neighborhood facilities for the elderly, paying special attention to the accelerated aging phenomenon in rural areas of Korea. We contrived a new index to measure spatial accessibility for people aged over 65 years, and we analyzed spatial accessibility by focusing on community facilities: public bath facilities, beauty shops, rural public facilities, markets, big stores, and large-scale retail shops. The most outstanding spatial accessibility among community facilities was found with the rural public facilities thanks to governmental installing adequate facilities in the past, followed by the beauty shops and the public bath facilities. In contrast, spatial accessibility of the markets was in the lowest. Spatial accessibility of community facilities for the elderly exhibited high variability among the rural areas. We confirmed significant inequality of spatial accessibility in all facilities we studied. The areas that had better spatial accessibility diverse combinations of the facilities. The areas that had worse spatial accessibility were, on the whole, consistent with traditional undeveloped regions. In the near future rational planning of facilities will be needed to supply adequate accessibility in targeted areas which currently had low accessibility. In order to improve the spatial accessibility of neighborhood facilities, the most essential factor is to take into account the geographical distribution patterns of rural settlements.

Purpose: Neuronal apoptotic events induced by aging and hypoxic/ischemic conditions is an important risk factor in neurodegenerative diseases such as ischemia stroke and Alzheimer's disease. The peel of Citrus sunki Hort. ex Tanaka has long been used as a traditional medicine, based on multiple biological activities including anti-oxidant, anti-inflammation, and anti-obesity. In the current study, we examined the actions of fermented C. sunki peel extract against cobalt chloride ($CoCl_2$)-mediated hypoxic death in human neuroblastoma SH-SY5Y cells. Methods: Cell viability was measured by trypan blue exclusion. Expression of apoptosis related proteins and release of cytochrome c were detected by western blot. Production of intracellular reactive oxygen species (ROS) and apoptotic morphology were examined using 2',7'-dichlorofluorescin diacetate (DCF-DA) and 4',6-diamidino-2-phenylindole (DAPI) staining. Results: Exposure to $CoCl_2$, a well-known mimetic agent of hypoxic/ischemic condition, resulted in neuronal cell death via caspase-3 dependent pathway. Extract of fermented C. sunki peel significantly rescued the $CoCl_2$-induced neuronal toxicity with the cell viability and appearance of apoptotic morphology. Cytoprotection with fermented C. sunki peel extract was associated with a decrease in activities of caspase-3 and cleavage of poly (ADP ribose) polymerase (PARP). In addition, increase in the intracellular ROS and release of cytochrome c from mitochondria to the cytosol were inhibited by treatment with extract of fermented C. sunki peel. Conclusion: Based on these data, fermented C. sunki peel extract might have a protective effect against $CoCl_2$-induced neuronal injury partly through generation of ROS and effectors involved in mitochondrial mediated apoptosis.

Korea is now entering into aging society next to Japan in Asia, which is considered as unusual in the semi-developed countries. More than 50 year-old consumer market is anticipated to grow to 28.7% of the total in 2010 from 20.4% in 2000. In particular, the silver market is estimated to be formed in full range in 2010 when the generation born in 50s and 60s after the Korean War start to retire. In this study, body shapes are classified as standard, obese, and tiny according to the previous studies based on the body shape characteristics and the body measurement of the Elderly Women. Based on the classification, we developed pattern of the panty for the obese Elderly Women to provide basic materials for the quality enhancement of the clothing of the increasing Elderly Women. The followings are the result of the study 1. To categorize the body shapes of the Elderly Women focusing on the lower half, we grouped the target subjects using the nested approach by the average standard deviation and the factor analysis minimal diffusion method. Accordingly, type 1 and 2 had 36 members respectively and type 3 had 43 members. In this study, two Elderly Women subjects with standard body shape falling under the type 1 were selected as the subjects. 2. In the second trial evaluation for the panty pattern for the Elderly Women 32 items for appearance test and 3 items for functional test were evaluated. The scores in leg, sideline and hip were shown high and the balance between the parts was maintained very well. In the functional test, the panty used to be too tight for the leg curve but in the second trial it was improved, too. In each item, the second trial test showed better score than the first trial test. Conclusively, the most optimal panty prototype for the Elderly Women was proposed according to the trial test result.

Recent genomewide association studies of large samples have identified genes that are associated with blood pressure. The Global Blood Pressure Genetics (Global BPgen) and Cohorts for Heart and Aging Research in Genome Epidemiology (CHARGE) consortiums identified 14 loci that govern blood pressure on a genomewide significance level, one of which is $CASZ1$ confirmed in both Europeans and Asians. $CASZ1$ is a zinc finger transcription factor that controls apoptosis and cell fate and suppresses neuroblastoma tumor growth by reprogramming gene expression, like a tumor suppressor. To validate the function of $CASZ1$ in blood pressure, we decreased $Casz1$ mRNA levels in mice by siRNA. $Casz1$ siRNA reduced mRNA levels by 59% in a mouse cell line. A polyethylenimine-mixed siRNA complex was injected into mouse tail veins, reducing $Casz1$ mRNA expression to 45% in the kidney. However, blood pressure in the treated mice was unaffected, despite a 55% reduction in $Casz1$ mRNA levels in the kidney on multiple siRNA injections daily. Even though $Casz1$ siRNA-treated mice did not experience any significant change in blood pressure, our study demonstrates the value of $in$ $vivo$ siRNA injection in analyzing the function of candidate genes identified by genomewide association studies.

This study was to verify the effectiveness of the Life Review-Narrative group therapy program on decreasing depression and death anxiety in the elderly. The program was organized according to a course of life from childhood to old age. The objectives were for the elderly to enhance self-worth, to become aware of their solitary existence, to accept aging and death, to accept the life: both past and present, and to make the most of experiences in overcoming difficulties. For the most part, the program used reminiscence and re-authoring of the narrative therapy as counseling techniques. Thirty-two elderly people(16 in the experimental group, 16 in the control group) aged 60 years and over were randomly selected from patients at the Daegu Metropolitan City General Welfare Center. Two groups were identified as equivalents for the study in the pre-test. The program for the experimental group was implemented twice a week for 90 minutes per session over a 6-week period(Sep. 8-Oct.14. 2005). The pre-test(Sep. 8 2005), the post-test(Oct. 14. 2005) and the follow-up test(Nov. 14. 2005) were implemented in order to verify the effectiveness of the programs. The instruments used in the study were the Geriatric Depression Scale Short Form(Korean Version) and the Death Anxiety Scale. The data were analyzed using t-testing and One-Factor Repeated Measures ANOVA. This study supplemented other qualitative research methods in order to verify the variation in the depression and death anxiety in the elderly. The findings of the study were as follows: Significant decrease in the depression and death anxiety were reported in the experimental group. The control group however did not show any significant changes in the depression and death anxiety rates. The result of the post hoc multiple comparisons showed that the effects of the life review-narrative group therapy program has lasted effects on decreasing of the death anxiety. Nevertheless, the effects of the life review-narrative group therapy program on decreasing depression are not lasting. The study has limitations so further research is suggested.

Road bridges are deteriorating gradually, and it is forecasted that the number of road bridges aging over 30 years will increase by more than 3 times of the current number. To maintain road bridges in a safe condition, current safety conditions of the bridges must be estimated for repair or reinforcement. However, budget and professional manpower required to perform in-depth inspections of road bridges are limited. This study proposes an estimation model for safety rating of road bridges by analyzing the data from Facility Management System (FMS) and Yearbook of Road Bridges and Tunnel. These data include basic specifications, year of completion, traffic, safety rating, and others. The distribution of safety rating was imbalanced, indicating 91% of road bridges have safety ratings of A or B. To improve classification performance, five safety ratings were integrated into two classes of G (good, A and B) and P (poor ratings under C). This rearrangement was set because facilities with ratings under C are required to be repaired or reinforced to recover their original functionality. 70% of the original data were used as training data, while the other 30% were used for validation. Data of class P in the training data were oversampled by 3 times, and Repeated Incremental Pruning to Produce Error Reduction (RIPPER) algorithm was used to develop the estimation model. The results of estimation model showed overall accuracy of 84.8%, true positive rate of 67.3%, and 29 classification rule. Year of completion was identified as the most critical factor on affecting lower safety ratings of bridges.

Objectives : The purpose of this study was to investigate the number of remaining natural teeth in elderly people visiting dental care services and the factors affecting dental visit. This study will contribute the development of oral health promotion programs for the elderly people. Methods : Subjects were 172 elderly people recruited from 217 senior citizens visiting public oral health care services in 16 districts in Busan. They completed self-Corresponding Author reported questionnaires. Results : Elderly people had less remaining natural teeth (p<0.001). The remaining natural teeth ($15.07{\pm}8.75$) of the health insurance beneficiary were majority than those of the medicaid ($8.78{\pm}8.45$)(p<0.001). The respondents with better oral health condition had more remaining natural teeth (r=0.317, p<0.001), and those who were more worried about oral health had less remaining natural teeth (r=-0.599, p<0.001). Aging accelerates loss of natural teeth (p<0.001) of 3.203. Approximately 2.188 remaining teeth will be preserved by oral health care improvement (p=0.009). Conclusions : Frequent dental clinic visit will prevent natural teeth loss in the elderly people. Toothbrushing is the most efficient method of oral health care in the elderly people. Awareness towards oral health care is the motivation to preserve natural teeth in the elderly people.
