  • This study aims at applying Photoshop functions to digital make-up(DM) for aging effect based upon the knowledge of phrenology, comparing the result with that of the real or off-line make-up(OM) and identifying any possible difference between two methods: which contributes to understanding the potential and problems of DM at application level. This study aims at suggesting a method to apply computer graphics(CGs) to special effect make-up for aging effect through a case, contributing to attracting academic concerns and building theoretical frameworks for DM. It used 'Aging Process' in Adobe Photoshop CS4 Extended(CS4E) to change a young girl into a senior lady. In the process of DM, the study applies various tools and methods to making face wrinkled, finds the most effective way among them for each area of face, suggests a method to integrate the ways and shows the result of the method. Compared with OM, DM using CS4E is the less constrained work regarding procedure and time. Specifically, it can save the time tremendously because the reiterative operation of work can be omitted, when the same work is repeated, using 'Action' function which memorizes the history of the work. Once a DM work is produced, since it is durable, reusable and convertible to various images with additional operations, it seems very economical as well as highly promising to market the work through on-line sales. Regarding face features and skin, it reviewed literature in make-up and phrenology while it used Photoshop CS4 Extended tools to demonstrate a case of aging effect by combining and painting pictures of a young lady and a senior citizen.

  • PURPOSES : This study aims to show the difference of the binder aging level in the hot-mix asphalt (HMA) mixture after short-term aging (SA) under different aging conditions, such as mixture temperature and duration in hour. METHODS : Three SA times (i.e., 1 h, 2 h, and 4 h) at two temperatures (i.e., $160^{\circ}C$ and $180^{\circ}C$) were used for the normal mixtures prepared using a PG64-22 asphalt. The field long-term aging (LA) was simulated by applying the same LA procedure (65 h at $110^{\circ}C$) to all compacted specimens, prepared at the air void of 7% using each SA-treated mixture, in a convection oven. The binder aging level was measured in terms of large molecular size by gel-permeation chromatography (GPC) from the mixture and the absolute viscosity (AV) from the recovered binder. The aging levels were evaluated using those two properties after SA and LA, and then compared based on the normal SA (NSA) mixture (1 h at $160^{\circ}C$). The service life reduction caused by SA in various conditions was estimated based on the aging level of the field cores from different locations in various service lives. RESULTS : The results of the laboratory evaluation indicated that the binder of the mixture, which was treated at longer SA time and higher temperature, showed a significantly higher aging level than the NSA mixture. The binder aging level from a longer time, such as 2 h and 4 h SA, or at a higher temperature ($180^{\circ}C$), were estimated to be similar to that of the mixtures, which had already been in field service for several years. CONCLUSIONS : The HMA mixture should be produced at a moderate temperature, such as $160^{\circ}C$, and placed within a limited hauling and queuing time to avoid a significant short-term aging of the binder before placement in the field pavement. The SA for a longer time at a higher temperature than the NSA condition was found to be detrimental to the service life of the asphalt pavement.

  • Objectives : We investigated the anti-aging effects on skin with Saccharomyces fermented modified Kyungohkgo extract (SFKE). Methods : Fermented modified Kyungohkgo extracts by 14 different kinds of microorganism were prepared and most effective Saccharomyces fermented modified Kyungohkgo extract among these was selected for anti-aging agent. We measured various effects related to skin such as scavenging activity against free radical, cell proliferation, collagen synthesis and toxicity of SFKE were evaluated and compared with modified Kyungohkgo extract (KE). Results : Free-radical scavenging activity and cell proliferating ratio of SFKE were 2 and 8 times higher than those of KE. The SFKE could significantly increase the collagen synthetic ratio compared with KE treated group. SFKE showed no toxicity at all tested concentrations. Conclusions : The results of our study propose that SFKE have good anti-aging effects on skin.

  • This paper reports the effects of curing temperature and aging on the strength and the modulus of elasticity. In oder to determine the strength and the modulus of elasticity with curing temperature and aging, experimental and analytical methods are adopted. The tests of 480 cylinders are carried out for type I, V and V with 15 percent replacement of fly ash cement concretes, which are cured at isothermal conditions of 10, 23, 35 and 5$0^{\circ}C$. and the concrete cylinders are tested at the ages of 1, 3, 7 and 28 days. According to the experimental results, the concrete subjected to high temperature at early ages attaines higher early-age compressive and splitting tensile strength but eventually attaines lower later-age compressive and splitting tensile strength. Even if modulus of elasticity has the same tendency, the variation of modulus of elasticity with curing temperature is smaller than that of compressive strength. Based on these experimental results, the relationships among compressive strength, modulus of elasticity and splitting tensile strength are proposed considering the effects of curing temperature, aging and cement type.

  • Background This study evaluated dynamic changes in eyebrow position related to aging. Methods Female participants were recruited and separated into two groups aged 20-30 years (the younger group, n=20; mean age, 24.8 years) and 50-70 years (the older group, n=20; mean age, 55.8 years). Photogrammetry was used to determine the eyebrow position at the medial canthus (MC), lateral limbus, lateral canthus, and lateral end point (EP) for 6 actions: smooth opening (the reference action) and closing of the eye, forward gaze, maximum opening and closing of the eye, and maximum frown. Videos were also recorded. Results No differences in eyebrow position were detected at the MC when opening or closing the eyes smoothly, gazing straight ahead, or closing the eyes maximally. For all 6 actions, the position of the lateral EP in the older group was significantly lower than in the younger group (P=0.003), and the smallest degree of vertical movement at this point was found in both age groups (P<0.001). Vertical movement at the 4 landmarks of the eyebrows decreased with aging. Conclusions Eyebrow position was unchanged at the MC with aging, except at maximal eye opening and maximal frown. No differences in eyebrow position were observed between the younger and older groups when eyes were maximally closed, except at the EP. It is important to focus on correction of the lateral EP for periorbital rejuvenation.

  • Objectives: It has been found that health promotion interventions are effective to decrease morbidity among older people. The acceptability of interventions are, however, still troublesome for achievement of efficacy of health promotion interventions. The current study examines the effects of age identity and attitude toward aging on the use of health promotion programs among older people. Methods: Data from the Survey of Living Conditions of Korean Older Persons were used. Logistic regression models were tested using a nationally representative sample of 9,461 community-dwelling older individuals who are 65 years old and over. Results: Older individuals who have younger age identity and more negative attitude toward aging were less likely to use health promotion programs, after adjusting the effects of other predisposing, enabling, and need factors such as demographic characteristics and personal health characteristics. Conclusions: Strategies for mitigating the possible effects of age identity and attitude toward aging on the acceptability of health promotion programs are also discussed.

  • Aging phenomena of 0.2PMN-0.8PZT multilayered ceramic actuators(MCA) have been investigated at the room temperature. The piezoelectric materials were synthesized as conventional ceramic process, and MCA were fabricatedby tape casting methods. The crystalline structures and lattice parameters were investigated by X-ray diffraction analysis, showing the structure was tetragonal and c/a was about 1.01. And, the effective electromechanical coupling coefficient keff and pseudo-piezoelectric constant $d_{33}$were measured. Variable unipolar electric fields, $2{\sim}4kV/mm$, were applied to MCh to investigate the aging characteristics. After 2 kV/mm unipolar electric field, keff and $d_{33}$ were 0.454 and 4.44 respectively. The measured and simulated values using for aging phenomena analysis, had a good fit to the linear logarithmic stretched exponential law.

  • Purpose: This was a methodological study that aimed to develop a measurement scale for aging anxiety among middle-aged women. Methods: In this study, construct factors were extracted, and a conceptual framework was established through an extensive literature review and in-depth interviews with middle-aged women. Under the conceptual framework, 44 preliminary items were constructed, and a preliminary scale of 25 items was completed after two rounds of expert validation and item review. For this study, data were collected from 201 women aged 40~59 years, and the construct validity and reliability of the preliminary scale were verified. Results: To verify the construct validity, exploratory factor analysis was conducted. Four factors containing 19 items were extracted. Concurrent validity of the developed scale was verified with Pearson's correlation analysis. The final scale comprised 4 factors ("Social valueless", "Physical weakness", "Concern about changes in appearance", and "Expectations of old age") and 19 items. The Cronbach's ${\alpha}$ value was .91. Conclusion: The scale for measuring aging anxiety in middle-aged women developed in this study validly reflected the peculiarities of aging anxiety in middle-aged women, who experience many physical, emotional, and social changes. The scale can be said to reflect the cultural background, as it reflected real experiences gained through in-depth interviews with middle-aged women.
