Purpose: The purpose of this study was to investigate expectations regarding aging by middle-aged women in the community, and identify factors contributing to their expectations about aging. Methods: Participants in the survey for this study were 303 middle-aged women from community health centers and religious facilities in Seoul, Gyeonggi Province, and Chungcheongbuk Province. Data were collected from March 2 to April 17, 2012 using self-report structured questionnaires. The instruments were the Health Perceptions, Rosenberg Self-esteem Scale (RSES), Family APGAR, Expectations Regarding Aging (ERA-12). The data were analyzed using t-test, one-way ANOVA, Scheffe test, Pearson correlation coefficients and hierarchical multiple regression with IBM SPSS/WIN 20.0 program. Results: Perceived health status (${\beta}$=0.16, p=.009) and self-esteem (${\beta}$=0.20, p=.001) of middle-aged women were identified as significant predictors of expectations regarding aging, after adjusting for age, education, occupation, monthly income and menstrual status. Conclusion: These results suggest that nurses should make an effort to improve expectations about aging among middle-aged women. Ultimately, community health programs for middle aged women need to be developed to achieve successful aging.

This study is conducted to survey and examine the relationships among anxiety about aging, perceived health status and health promoting behaviors in the elderly, and to provide basic data for health promoting interventions that would improve their successful aging. Me1hods: Data in this study was collected from 333 elderly participants living in Susan. Descriptive statistics, t-test or ANOVA with Scheffe's test, Pearson's correlation coefficients and stepwise multiple regression were used for data analysis. Results: The major findings of this study were as follows. 1) The mean score of anxiety about aging was 2.67 $\pm$ 0.30, perceived health status 2.46 $\pm$ 0.37, and health promoting behavior 2.77 $\pm$ 0.21.2) There was a positive correlation between health promoting behavior and perceived health status (r = 267, P= .000). There was a negative correlation between anxiety about aging and health promoting behavior (r = -.163, P=.003). 3) Health-promoting behavior was significantly associated with perceived health and anxiety about aging, which explained 20.9% of variance in health-promoting behavior. Conclusion: In order to promote perceived health status and to decrease anxiety about aging in the elderly, it is necessary to develop supporting interventions to decrease anxiety about aging

The purpose of this study is descriptive research to understand the effects of somatic symptoms, aging anxiety, and social support of middle-aged women on depression. Data collection was conducted from March 2020 to May 2020 using a structured questionnaire from a sample of 110 middle-aged women. The collected data were analyzed using descriptive statistics, t-test, ANOVA, Kruskal-Wallis test, Pearson's correlation coefficients and multiple linear regression analysis using SPSS Window 25.0 program. As a result of the study, the influence factors on the depression were confirmed by the somatic symptoms(β=0.42, p<.001), aging anxiety(β=0.35, p<.001) and total explanatory power of the variables was found to be 48.0%. Therefore, based on the result of this study, it suggests that more research is needed a program that considers somatic symptoms and aging anxiety when developing interventions to reduce depression and to verify the effectiveness.

The chief factors for the penetration and diffusion of chloride ions in concrete are water-cement ratio(W/C), aging, curing conditions, chloride ions concentration of given environment., wet and dry conditions and etc. In this study, of these factors effect of curing conditions such as standard and outdoor curing on the characteristics of chloride ions diffusion in concrete were researched when environmental factors for the penetration and diffusion of chloride ions were constant. For this purpose, the voltages passing through the diffusion cell were measured by using accelerated test method using potential difference, and then diffusion coefficients of chloride ions by using Andrade's method were estimated for 44%, 49.5% and 60% of w/c, respectively. As a result., according to curing conditions correlation among diffusion coefficients of chloride ions, W/C and aging were concluded through multiple regression model.

In this paper, a new efficient feature extraction method based on Daubechies discrete wavelet transform is presented. This paper especially deals with the assessment of process statistical parameter using the features extracted from the wavelet coefficients of measured acoustic emission signals. Since the parameter assessment using all wavelet coefficients will often turn out leads to inefficient or inaccurate results, we selected that level-3 stage of multi decomposition in discrete wavelet transform. We make use of the feature extraction parameter namely, maximum value of acoustic emission signal, average value, dispersion, skewness, kurtosis, etc. The effectiveness of this new method has been verified on ability a diagnosis transformer go through feature extraction in stage of aging(the early period, the middle period, the last period)

The nondestructive testing methods are commonly used to determine the in-situ compressive strength of concrete. The correlation curves to evaluate the effect of aging on the development of concrete strength was proposed. Thirty two ${\Phi}10{\times}20cm$ cylinder specimens were cast from 5 batches having different strength levels. The correlation curves for rebound hammer method, ultrasonic pulse velocity method and combined method were derived from the laboratory tests and multiple regression analysis. To account for the change of condition such as surface hardness, internal moisture contents, the aging coefficients are applied to the correlation curves. From the comparison the nondestructive strength with the core strength taken from the existing reinforced concrete structures, the validity of the proposed correlation curves are verified.

This study was carried out to examinate the effect of aging period on chromatic, chemical and organoleptic characteristics, and to evaluate of optimum aging period for each grade in burley leaf tobacco. The leaf tobaccos were produced in 2000, and threshed, redried and packed in carton box under the current methods. Four grades of processed leaf(A3T, B1T, C1W and D3W) were stored during 24 months (May 10, 2001 to April 31, 2003) in warehouse of Chungju Leaf Tobacco Processing Factory. The leaf tobaccos were sampled at three month intervals for analysis of chromatic, chemical and organoleptic properties. pH values of four grades, and Yellow(b) of A3T and BIT were also significantly decreased during the aging. Filling values, tar, nicotine and CO contents of tobacco smoke, and puff number of cigarettes were not significantly changed during the aging. Positive correlation coefficients were significantly observed between irritation of the calculated attributes from contents of volatile oil components in leaf tobacco and that of the panel sensory attributes. The ratio of maximum change in irritation attribute was larger than that in taste attribute during aging. The calculated irritations of 18～24 months aging for A3T and B1T were significantly lower than zero-aging, while those of C1W and D3W were not significant among aging periods. The panel irritations of 12～15 months aging for four grades were low tendency. The results suggest that decrease of aging period for thin leaf from 21～24 to 12～15 months may be beneficial to save storage cost in burley tobacco.
