Purpose: This study aims to examine the relationship between ego resilience, family resilience, and the perception of successful aging in nursing students; additionally, specific factors relating to the perception of successful aging were identified. Methods: The participants comprised 154 nursing students. Data were collected through the administration of self-reported questionnaires. Data analysis was then performed utilizing a t-test, an ANOVA, Pearson's correlation coefficients, and a multiple regression analysis. Results: Family resilience differed significantly based on the type of residence (p=.020) (i.e., living with grandparents (p=.048)). Perception of successful aging differed significantly based on grade (p<.001). The perception of successful aging showed a positive correlation relative to mode of communication and organizational pattern. The mode of communication accounted for 4.7% of perception of successful aging. Conclusion: The significance of the study on the importance of mode of communication was confirmed by identifying the effects of the perception of successful aging. Nursing students may actively cope with crises through communication; thus, successfully recognizing aging in order to lead a healthy life. Furthermore, having a high perception of successful aging while treating an increasing number of elderly patients at the clinical practice is believed to have a positive effect on patient care.

Recently polymer insulators are being used for outdoor high voltage applications. Polymer insulators for transmission line have significant advantages over porcelain and glass insulators, especially for ultra-high voltage transmission lines. Their advantages are light weight, vandalism resistance and hydrophobicity. Polymer insulators are a relatively new technology, but their expected life is still unknown. Therefore these estimating technique are very important. Their life time is related to weathering and operating condition. Multi-aging test is requested because aging factor is occurred by multi-aging than unique aging. The aging test about polymer insulators have mainly carried out by IEC 61109. This paper presents multi-stress chamber experiments and tracking wheel test to examine the tracking and erosion performance of polymer insulator for transmission. Multi-stress testing is able to demonstrate deficiencies of polymer insulator materials and designs, including the nature of interfaces in insulation design. We have investigated IEC 61109 Annex C (5000h aging test) and CEA tracking wheel test as test methods of artificial accelerated aging. The aging degree of polymer insulator is estimated by leakage current, measurement of hydrophobicity degree, damage conditions of insulator surface, withstand voltage test etc.

Purpose: Aging process comes with cognitive impairment due to decreased neuronal cell number, activity, and neuronal circuit. Alteration of inhibitory neurons contributes to cognitive impairment in normal aging and is responsible for disrupting the excitation/inhibition balance by reducing the synthesis of gamma-aminobutyric acid (GABA). Morus nigra (Mulberry) is a natural physiologically active substance that has been proven to have anti-oxidant, anti-diabetic, and anti-inflammatory effects through many studies. This study aimed to evaluate the effects of the mulberry extract (ME) on cognitive function through anti-oxidant enzyme and GABAergic neuronal activity in aged rat brain. Methods: Sprague Dawley rats were randomly assigned as the young group (8 weeks, n= 8), aging group (67 weeks, n= 8), and aging+ mulberry extract group (67 weeks, n= 8). The aging+ mulberry extract group was orally administered 500 mg/kg/d mulberry extract for 6 weeks. Results: The aging+ mulberry extract group improved spatial and short-term memory. The antioxidant potential of ME increased the expression of superoxide dismutase-1 (SOD-1) and decreased inducible nitric oxide synthase (iNOS). Also, the aging+ mulberry extract group significantly increased the expression of GABAergic interneuron in hippocampus cornu ammonis1 (CA1) compared to the aging group. Conclusion: The number of GABAergic inhibitory interneurons was deceased and memory functions in the aging process, but those symptoms were improved and restored by mulberry extract administration.

Purpose: The purpose of this study was to investigate the aging anxiety, factors of successful aging, and preparation for aging in early and late middle-aged people. Methods: The study subjects were 140 middle-aged people aged from 40 to 59. Data were collected using a self-administered questionnaire from August 16 to September 30, 2013. The collected data were analyzed with descriptive statistics, t-test, ${\chi}^2$-test and Pearson correlation coefficient using IBM SPSS 21.0 program. Results: Between early and late middle age, there were statistically significant differences in the subcategories of aging anxiety: fear of loss (t=2.93, p=.004), fear of old people (t=-2.33, p=.021), physical appearance (t=2.32, p=.022), and psychological concerns (t=2.04, p=.043). A statistically significant difference was found between two groups in one subscale of preparation for aging: physical preparation (t=-2.02, p=.045). In early midlife, significant associations were observed between preparation for aging and both aging anxiety (r=.56, p<.001) and factors of successful aging (r=.54, p<.001). In late midlife, preparation for aging and factors of successful aging showed positive correlation (r=.50, p<.001) Conclusion: Results of this study indicate that programs for successful transition to old age in middle-aged people should consider their aging anxiety level and preparation for aging at their stage of life.

In Oriental medicine, aging is just a natural process like change of seasons. Ancient Oriental people accepted it as a natural thing to be growing older and to die at last. The science of aging has advanced dramatically. In the last 2 decades, advances in genetics and molecular biology have led to extraordinary new understandings in how cells age, how apoptosis programs cells to die, and how neuroendocrinology plays a role in the lifespan of organisms. Today, the matter of primary concern about aging is a cellular and mitochondrial damage of human body induced by reactive oxygen species(ROS). The skin aging can be divided into two areas, intrinsic(chronologic)-aging and photo-aging. There are lots of photo damage about skin aging. The skin is increasingly exposed to ultraviolet(UV) irradiation in life. Therefore, the risk of photo-oxidative damage of the skin induced by reactive oxygen species(ROS) has increased substantially. Nowadays, many people believe that they can stop or at least delay the process of aging. There are lots of treatments that promise to slow the process of aging and the associated ailments. Many of these treatments, for example, exercise, Vit E, Vit C therapy, hormone therapy, restrict diet, are gradually being subjected to clinical trials. But in spite of all efforts, researches and investigations, there is no single method or treatment which is revealed to be truly effective for delaying progress of aging. Every methods insisted on effect for delaying aging process, has its dark side. All we can do is just keeping ourself healthy until the time of death.

PURPOSE. The aim of this study was to evaluate effect of different surface treatment methods on the bond strength between aged composite-resin core and luting agent. MATERIALS AND METHODS. Seventy-five resin composites and also seventy-five zirconia ceramic discs were prepared. 60 composite samples were exposed to thermal aging (10,000 cycles, 5 to $55^{\circ}C$) and different surface treatment. All specimens were separated into 5 groups (n=15): 1) Intact specimens 2) Thermal aging-air polishing 3) Thermal aging- Er:YAG laser irradiation 4) Thermal aging- acid etching 5) Thermal-aging. All specimens were bonded to the zirconia discs with resin cement and fixed to universal testing machine and bond strength testing loaded to failure with a crosshead speed of 0.5 mm/min. The fractured surface was classified as adhesive failure, cohesive failure and adhesive-cohesive failure. The bond strength data was statistically compared by the Kruskal-Wallis method complemented by the Bonferroni correction Mann-Whitney U test. The probability level for statistical significance was set at ${\alpha}$=.05. RESULTS. Thermal aging and different surface treatment methods have significant effect on the bond strength between composite-resin cores and luting-agent (P<.05). The mean baseline bond strength values ranged between $7.07{\pm}2.11$ and $26.05{\pm}6.53$ N. The highest bond strength of $26.05{\pm}6.53$ N was obtained with Group 3. Group 5 showed the lowest value of bond strength. CONCLUSION. Appropriate surface treatment method should be applied to aged composite resin cores or aged-composites restorations should be replaced for the optimal bond strength and the clinical success.

Purpose: This study was designed to construct and test a structural equation modeling on specific domain health status and the Selection Optimization Compensation (SOC) strategy affecting successful aging in elderly people. Methods: The model construction was based on the SOC model by Baltes and Baltes. Interviews were done with 201 elderly people aged 65 or older. Interview contents included demographics, functional health status, emotional health status, social health status, SOC strategies, and successful aging. Data were analyzed using SPSS 15.0 and AMOS 7.0. Results: Model fit indices for the modified model were GFI=.93, CFI=.94, and RMSEA=.07. Three out of 7 paths were found to have a significant effect on successful aging in this final model. Functional health status had a direct and positive effect on successful aging. Emotional health status influenced successful aging through SOC strategies. Conclusion: This study suggests that interventions for improving functional health status and for strengthening SOC strategies are critical for successful aging. Continuous development of a variety of successful aging programs using SOC strategy is suggested.

Purpose: This study was conducted in order to the relationship between life satisfaction, health behaviors, and successful aging and factors associated with successful aging. Methods: Participants in this study included 159 elders living in one city. Data on life satisfaction (Choi's Life Satisfaction Scale for Korean elderly, 1984), health behaviors (Choi & Kim's Health Behaviors Scale for Korean elderly, 1997), and successful aging (Kim & Shin's Successful Aging Scale for Korean elderly, 2005) were collected by trained interviewers. For analysis of collected data, the PASW 18.0 program was used, which included descriptive analysis, t-test, ANOVA, Scheffe test, Pearson correlation coefficients, and Multiple regression. Results: Results showed a positive correlation between life satisfaction, health behaviors, and successful aging. Life satisfaction, self-perceived health status, and health behavior explained 60.8% of successful aging. Conclusion: There is a need to help improve health behavior and self-perceived health status of elders. We should also understand life satisfaction over their life span and establish a program that encourages healthy behavior in the community. Accordingly, these efforts will allow for achievement of a more successful aging process for the elderly.

There are no reliable data about the effect on the baking industry in Korea yet. The damage caused by the product's aging is so much in the confectionary and baking industries. Therefore, the aging of bread is an economical problem which determines its commercial lifespan. In order to solve out this aging problem, this article dealt with the factors which give rise to the effect of starch on the aging and its inhibitory methods. 1. Control of the moisture content : Because the aging of starch occurs at 30~60% of moisture most frequently, controlling the moisture content above or below the above percentage can help restrain the aging to a certain degree. 2. Addition of sugars : The sugars become hydrated through hydrogenation with the moisture in the food. Thus, the sugars suppress the phenomenon of crumbling inside the food acting as a kind of dehydrator. 3. Use of an emulsifying agent : The emulsifying agent increases the stability of starch colloid liquid and suppresses the precipitation of starch molecules and the formation of crystallized range to prevent aging. 4. Method by freezing : The aging of starch does hardly occur reaching -2$0^{\circ}C$~-3$0^{\circ}C$ below zero. 5. Maintenance of warm condition : The freshness of bread is maintained at the 80% of humidity at 5$0^{\circ}C$.
