Objectives : This study aims to analyze the terms describing anti-aging effects in Dongeuibogam, and to propose the methodology for selecting medicinal herbs related to anti-aging effects. Methods : We considered aging or anti-aging theories by reviewing the major literature in korean medicine or traditional chinese medicine, and then we deduced the concepts describing anti-aging effects and the medicinal herbs for anti-aging effects. We investigated the medicinal herbs based on the terms describing anti-aging effects in Dongeuibogam and drew the methodology for selecting and classifying the medicinal herbs related to anti-aging. Results & Conclusions : The following conclusions could be drawn. 1. A set of causes and signs of aging in Dongeuibogam and a set of therapies for alleviating the aging signs in Chengumikbang, Yanglobongchinseo, and Nolohangeon was found. 2. Anti-aging effects should not be confused with disease treatments. Therefore, we defined the medical terms of anti-aging effects as "the terms expressing the effect of delaying or alleviating the subjective or objective signs of aging concretely". Based upon the terms of anti-aging effects, we defined the medicinal herbs for anti-aging effects as "the medicinal herbs whose effects are described in medical terms expressing the effects of delaying or alleviating the subjective or objective signs of aging concretely". 3. We considered Lycii Fructus, Asparagi Tuber in Dongeuibogam as examples of medicinal herbs whose effects are described in medical terms expressing anti-aging effects. It shows that we can select medicinal herbs for anti-aging effects by comparing the effects of 937 single therapies in Dongeuibogam to the terms describing anti-aging effects defined in this study. Futhermore, the results could be utilized as the basic materials of experimental study on anti-aging.

Objective : The purpose of this study is to understand aging and skin aging with both western and Korean medicine. Methods : We investigated the comprehension of general aging and skin aging in both western and Korean medicine through literature review. Result : The results are as follows. 1. Aging in western is a complex process influenced by telomere shortening and damage to cellular DNA. In Korean medicine, it is supposed that decline of interaction between yin(陰) and yang(陽) makes aging. 2. Skin aging in western medicine consists of intrinsic aging and extrinsic aging. In Korean medicine, skin aging goes with the aging of whole body and distinctive features of geroderma notice the unbalance of the whole body function. 3. Generally geroderma has decreased development of cells and low immunity, which is the function of kidney(腎) in Korean medicine. Conclusion : Further studies are needed to apply comprehension of skin aging in Korean medicine to clinical stage.

As the operating time in nuclear power plants (NPPs) increases, the integrity of nuclear components may be continually degraded due to aging effects of systems, structures and components. Recently, a number of NPPs are being operated beyond their design life to produce more electricity without shutting down. The critical issue in extending a lifetime is to maintain the level of safety during the extended operation period while satisfying the international regulatory standards. Therefore, it is beneficial to build a monitoring system to measure an aging status. In this paper, the Aging Monitor (AM) based on lots of aging database obtained from the operating plants and research results on the aging effects was developed to monitor, manage and evaluate the aging phenomena systematically and effectively in NPPs. The AM for the CANDU is divided into 6 modules: (1) Aging Alarm/Coloring Monitor, (2) Aging Database, (3) Aging Document, (4) Real-time Integrity Monitor, (5) Surveillance and Inspection Management System, and (6) Continued Operation and Periodic Safety Review (PSR) Safety Evaluation. The proposed system is expected to provide the integrity assessment for the major mechanical components of an NPP under concurrent working environments.

Purpose: In this study, we sought to identify the impact of aging anxiety and successful aging on the personality traits of elderly. Method: Subjects were 108 elderly persons aged more than 65 years. Data collected from June to November 2015 were analyzed using descriptive statistics, t-tests, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression. Results: With regard to the mean scores of personality traits, conscientiousness yielded the highest score, and neuroticism the lowest. The mean score on aging anxiety was below average, and that on successful aging was above average. Aging anxiety differed significantly according to age, present job, economic status, and health status. Successful aging differed significantly according to having a spouse, economic status, and health status. Significant correlations were found between anxiety and conscientiousness, extraversion, and neuroticism, and between successful aging and conscientiousness, agreeableness, extraversion, openness, and neuroticism. Conscientiousness and neuroticism had an effect on aging anxiety (23.2%), whereas conscientiousness, agreeableness, extraversion, openness, and neuroticism affected aging anxiety (45.3%). Conclusion: These findings indicate that personality traits reduce aging anxiety and lead to successful aging among elderly.

The life history of man is summarized as a birth-aging-disease-death. Man eventually ages and dies. How long can humans live? What is aging? Why do we age? Is aging inevitable? Can we rejuvenate? Recent researches on biological aging suggest that humans might overcome aging and rejuvenate. In this paper, we review the biologic characteristics of aging and the latest results of biological aging research, implicating that aging can be controlled, further treated, and that humans can ultimately be rejuvenated.

Although everyone grows old, perception about the aging process and aging as measured physiologically vary widely. Perecptions of aging have psychologically influence on physical aging. This study was to examine the relationships between, self-concept, perception of aging, and physical aging in the elderly and to contribute to the theory development which may direct nursing intervention to promote well-being of the aged. Subjects were 70 women residents of a nursing home for the elderly in Seoul. Data collection was done from May 15 to June 15, 1988 using interview schedules and mechanical instruments. The instruments were selected items from the Health Self Concept Scale developed by Jacox and Stewart for self concept, and Secord and Jourad's Body Cathexis Scale and Osgood's Semantic Differential Scale for perception of aging. Physical aging was measured by mechanical instruments, inspection, questions, and palpation. The data were analysed for mean, 1-test, ANOVA, and Pearson Correlation Coefficient using an S.P.S.S computerized program. The results of the analysis were as follows. 1. The mean level of self concept for the subject group was 16.97(SD＝$\pm$6.17)in a range from 6-30. The mean level of perception of aging was 39.6. (SD＝$\pm$6.51) in a range from 13-65. The mean level of physical aging was 14.09(SD＝$\pm$2.05)in a range from 8-40. 2. Relationships among self - concept, perception of aging, and physical aging. 1) There was a positive relationship between self-concept and perception of aging(r＝0.4461, p＝0.000). 2) There was a negative relationship between physical aging and perception of aging(r＝-0.2975, p＝0.006). 3) There was a tendancy toward a negative relationship between physical aging and self -concept, but not a significant relationship (r＝-0.1033, p＝0.197). 3. 1) No general charcteristic variables were related to self concept. 2) The general characteristic variable related to the level of perception of aging was religion (t＝4. 17, p＝0.001). 3) The general characteristic variable related to the level of physical aging was age (F＝12.008, p＝0.000). There was a significant relationship between self - cencept and perception of aging, and between physical aging and perception of aging. Therefore nursing intervention should focus on promoting a positive perception of aging and strengthening self- concept during the physical aging process.

Aging is one of the major tasks that our country should resolve. To deal with aging problems, many countries have introduced various new concepts such as active aging, productive aging, and successful aging, well aging and anti-aging. This study suggests a new concept, digital aging, to tackle aging problems, and we use this concept to explore the new policy and policy areas for aged people. Since this concept is not well defined yet, this article focuses reviewing existing research literature. Instead of focusing the negative aspect of aging, this study investigates how to use the digital technology to build such images that the old man can be continuously learning, active and productive.

This study aimed to investigate changes in the quality of meat aged using Jeju scoria earthenware. Water-holding properties, pH, color, tenderization, fatty acid composition, and free amino acid characteristics of aged pork loin were evaluated to determine the effects of wet and dry (normal and Jeju Scoria) aging methods and aging time (0, 10, 20, 30, and 40 days) on meat quality. The aging methods altered pH and CIE L^* after 10 days of aging. However, the aging method did not alter the pH and CIE L^* of the aged pork loin after 10 days of aging. The shear force was significantly lower in the Scoria aging method than in the wet aging method after 10 and 20 days of aging. Both the normal and Scoria aging methods increased aging loss compared to the wet aging method, which could be attributed to longer air exposure times of the two non-packaged aging methods than in the packaged aging method. The scoria aging method had significantly higher contents and ratios of saturated (SFA) to mono-unsaturated fatty acids but lower ratios of poly-unsaturated fatty acids to SFA than the wet aging method. The content of most free amino acids significantly increased with aging time, especially those related to the sweet, and umami categories. In summary, this study suggests that the Scoria aging method provides positive aspects of eating quality, such as improvement of meat tenderness and taste, including umami, with minimum changes in the overall meat quality.
