This study was designed to analyze the results of Vaso-Aging Degree in Oriental medical examination. The subjects were workers in the automobile manufacturing industry. The subjects consisted of 24,077 industrial workers who had received Oriental medical examination by Oriental medicine and they submitted questionnaires about drinking history and smoking history, during 9 months from March to November. They were categorized by job class, drinking history and smoking history, exercising history. The percentage of Vaso-Aging Degree were measured by using SA3000P(Medicore, Seoul, Korea). We analyzed the relationship between job class, drinking history, smoking history, exercising history and Vaso-Aging Degree using ${\chi}2$-test of the SPSS Ver. 14.0. In job class, Sales personnel were apt to have a higher level of Vaso-Aging Degree than Office workers. And getting older workers are, the higher Vaso-Aging Degree becomes. Vaso-Aging Degree of the Drinker group showed a higher level than the Non-Drinker group. Vaso-Aging Degree of Smoker group were higher than the Non-smoker group. On the other hand, Vafo-Aging Degree of Non-Exerciser group were higher than the Exerciser group. They have to manage Vaso-Aging Degree closely and educate the workers to quit smoking and drinking for their health promotion. Furthermore, continuous health check up needs to be done connectedly.

Objectives : This study investigated the relationship between smoking and health factors including stress resistance, stress index, fatigue and vaso-aging degree. Methods : The subjects were 19,953 persons who had received health examination by Korean Medicine and submitted questionnaires about smoking history, for 8 months from March to November in 2011. The stress index and resistance, fatigue were measured by HRV(Heart Rate Variability). The vaso-aging degree were measured by APG(Accelerated Photoplethysmograph). Results : Regarding the relationship between smoking and stress index and resistance, fatigue and vaso-aging degree were significant differences(p<0.05). Conclusions : This study suggests that smoking affects health factors including stress, fatigue and avaso-aging degree.

Objectives This study investigated the relationship between exercise and health factors including vaso-aging degree, stress index, stress resistance, fatigue and activity of autonomic nerve system etc. Methods The subjects were 20,509 persons who had received health examination by Korean Medicine and submitted questionnaires about exercise history, for 8 months from March to November in 2011. The vaso-aging degree were measured by APG (Accelerated Photoplethysmograph). The stress index and resistance, fatigue and activity of autonomic nerve system were measured by HRV (Heart Rate Variability).

Results Regarding the relationship between exercise and vaso-aging degree, stress index, stress resistance, fatigue and activity of autonomic nerve system, there were significant differences(p<0.05). Conculsions This study suggests that vaso-aging degree, stress index, stress resistance, fatigue and activity of autonomic nerve system are affected by exercise.

This study investigated the relationship between drinking and health factors including vaso-aging degree, stress index, stress resistance, fatigue and activity of autonomic nerve system etc. The subjects were 20,925 persons who had received health examination by Korean Medicine and submitted questionnaires about drinking history, for 8 months from March to November. The vaso-aging degree were measured by APG (Accelerated Photoplethysmograph). The stress index and resistance, fatigue and activity of autonomic nerve system were measured by HRV (Heart Rate Variability). We analyzed the relationship between drinking and various variables by chi-square test with SPSS ver. 19.0. Regarding the relationship between drinking and vaso-aging degree, there was significant differences(p<0.05). But regarding the relationship between drinking and the other factors, there were no statistically differences. This study suggests that the vaso-aging degree is affected by drinking alcohol.

Effect of an accelerated iso-thermal aging (375 degree C x 66days, 375 degree C x 200days) on elastic-plastic fracture resistance curve were examined in SA533B low alloy steel. Fracture toughness test are conducted by unloading compliance method at room temperature. But the apparent negative crack growth phenomenon, usually arise in partial unloading compliance test. The phenomenon of negative crack growth may be eliminated by the offset technique. There is no effect of aging on J sub(IC) and dJ/da in iso-thermal aged (375 degree C x 66 days) specimen, but there is very little effect in iso-thermal aged (375 degree C x 200 days) specimen.

The purpose of this study is to analyze the effects of the degree of preparation for old age and perception of successful aging on the life satisfaction of middle-aged women. The participants in this study were 300 women ranging in age from 35 years to 65years who reside in Seoul, Gyeonggi-do, and other cities. Two hundred eight self-reported questionnaires were used for final analysis by SPSS WIN14. The major results of this study were as follows: First, there were differences in the degree of preparation for old age of middle-aged women by age, academic career, income, area, and religion. Second, there were differences in self-efficacy in the perception of successful aging by academic career, an income, and area. Third, there were differences in the degree of life satisfaction of middle-aged women by academic career and income. Finally, the most effective variables on the degree of life satisfaction were the degree of preparation for old age, perception of successful aging, and income. Consequently, to improve the life satisfaction of middle-aged women, social groups, local self-governments, and the government have to educate women on economic management for preparation for old age and human relationship progress programs, as well as promote healthy leisure cultures.

The partial discharge has been blown as the chief breakdown of power equipments. The analysis and the recognition is much difficult because the partial discharge signal is very small and has complex aging pattern. Recently, insulation aging diagnosis based on pattern of phase(Ф), partial discharge magnitude(q), number(n) has been very important. Owing to depreciate the reappearance of aging progress at the electrical tree pattern and to be difficult to analyze visually, the study on partial discharge pattern is suggested to normalizing analysis method of partial discharge signals. This parer is purposed on prediction of life-time measurement of cv-cable, on decision of risk degree with normalization and real-time measurement of partial discharge signals for aging diagnosis of cv-cable. As normalizing the aging signals of electrical tree in cv-cable, it is able to confirm risk degree of insulation material with the distribution of Ф-q-n and recognize the process of aging pattern using neural network.

In this study, we investigated the durability properties of the recycled leather using shaving scrap with antioxidant. Recycled leather sheets were manufactured by mixing shaving scrap and NB latex as a binder. HALS(Hindered Amine Light Stabilizer) and UVA(UV absorbers) were used as antioxidant. Mechanical properties such as hardness, tensile strength, elongation, tear strength and abrasion resistance were measured. Light aging resistance was evaluated using UV lamp and the degree of discoloration of the recycled leather sheets using a gray scale. In addition, to evaluate heat aging and UV aging, the degree of discoloration of the recycled leather sheets over time was measured using colorimeter. Washing fastness was evaluated on the degree of dyeing of recycled leather sheets for six type of multi-fiber woven fabrics (Acetate, Cotton, Nylon-66, Polyester, Acryl, Wool). To determine whether hazardous substances were detected in recycled leather sheets, the contents of arylamine and Cr 6⁺ were evaluated. As a result, when used in combination with antioxidant, the heat aging and light aging of recycled leather were improved and hazardous substance were not detected.
