Senescent effects are the gradual deterioration of function caused by biological aging. Senescent effects on color vision are not clearly understood even after considerable researches. Part of the reason is that the color vision is a complex phenomenon resulting from various factors such as organic systems, and the physical (neuro-optical) and the psychological (experiential) processes of color perception. We performed a field experiment on color perceptional differences due to aging vision. Our experiment was applied to two different groups in South Korea: an experimental group (46 subjects of over the age of 61 years) and a control group (49 subjects in their twenties). The experimental tools are comprised of (1) six gradual yellowing detector board (40%, 50%, 60%, 70%, 80%, 90%); (2) pairs of vivid-strong, vivid-deep, grayish-deep, deep-dull, and bright-light tones of Blue (B) and Purple (P) colors; (3) Red (R), Yellow (Y), Green (G), Blue (B), and Purple (P) colors of dull-tones and pale-tones; and (4) a questionnaire on the semantic differential scales of the color images and color differences. A diagnosis system of gradual yellow vision, developed by the authors for this study, was adapted to generate the color detecting boards. The results are as follows. (1) There are significant differences between the two groups in detecting colors that simulate 40% and 50% of yellow vision. (2) As to the color difference detecting ability between similar tones, the experimental group shows difficulties in pairs of vivid-strong tones and deep-dull tones of the B color. And (3), the emotional responses to the dull tone and the pale tone are not stable in the red, the yellow, blue, and purple. Thus, we empirically demonstrate the specific differences in color perception between the old and young groups.

Elderly population has increased rapidly and adjusting the environment is in demand to support their health. To improve the living environment of elderly, an appropriate plan for customized home modification is needed upon the personal contexts. The purpose of this study is to explain the sequence and to build an insight on customized home modification for vulnerable single elderly. It is a case study based on single target that includes 6 months of execution period deeply seeking the appropriate plan for implementation. The target is a male elderly aged 74 living in a single story detached house. The various research methods are applied in this study including exploratory, participatory, action and trade-off preference researches. The result shows that plan for home modification is complex outcome of interlocking uniqueness between residence environment and resident situation. If customized modification is targeted for residentially vulnerable social group, more sensitive approach aiming for the highest result is required due to financial constraint. To conclude, comprehensive understanding of overall circumstances of a dwelling, a resident and various stakeholder is essential throughout the process. Since the aging-in-place of elderly cannot be achieved without self-sustaining living environment, customized home modification should be a tool to meet housing suitability. It is important to strengthen the experts and future workforce with networks of local residents to share opinions and appropriate plans.

According to "Dongeuibogam(東醫寶鑑)", "the Shinnong Herb Bible(神農本草經)", "Chamdonggo(參同攷)", come to the conclusion about medical thought of "the Zhouyi Cantongxie(周易參同契)". Alchemy is a common field both on the eastern and western civilization, but a process of development is different. Ancient chinese alchemist made a study on external alchemy, but harmful consequences of external alchemy was consecutive, many scholars had turned their interest on internal alchemy which is related in human meridian biology and spirit. In the western alchemy has developed to make a study on analytic psychology and science of religion. Most importantly, the eastern and western alchemy have something in common what at the point of the perfection of self is similar, but the name is different, for example in the eastern alchemy we can be immortals and take a spiritual enlightenment with the elixir of life, in the western we can take a cure of souls as a christian. As for internal alchemy, "Cantongxie(參同契)" gives influence to the theories such as the theory of danjeon(lower part of the abdomen), evolution, aging, and life nurturing. Especially, the theory of danjeon shows such merit for studying since it is similar to triple energizers(三焦) and the theory of qi street(氣街) of oriental medicine. The study on "Cantongxie(參同契)" was achieved in Korea too, especially Chosun dynasty. "Candongkao (參同攷)" by Seo Myung-eung(徐命膺, 1716~1787) are representative. According to "Candongkao(參同攷)", Geon(乾), Gon(坤), Gam(坎), and Ri(離), the four trigrams for divination, each are affiliated with lungs, spleen, kidneys, and heart. Nowadays the study on alchemy correspond with modern trends, which are anti-aging and living without any disease. If processed mineral drugs is assured for stability, it can be used for incurable diseases such as cancer.

Free radicals and reactive oxygen species (ROS) caused by UV exposure or other environmental factors are critical players in cellular damage and aging. In order to develop a new antiphotoaging agent, this work focused on the antioxidant effects of the extract of tinged autumnal leaves of Acer palmatum. One compound was isolated from an ethyl acetate soluble fraction of the A. palmatum extract using silica gel column chromatography. The chemical structure was identified as apigenin-8-C-beta-D-glucopyranoside, more commonly known as vitexin, by spectral analysis including LC-MS, FT-IR, UV, $^{1}H-$, and $^{13}C-NMR$. The biological activities of vitexin were investigated for the potential application of its anti-aging effects in the cosmetic field. Vitexin inhibited superoxide radicals by about $70\%$ at a concentration of $100\;{\mu}g/mL$ and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals by about $60\%$ at a concentration of $100\;{\mu}g/mL$. Intracellular ROS scavenging activity was indicated by increases in dichlorofluorescein (DCF) fluorescence upon exposure to UVB $20\;mJ/cm^2$ in cultured human dermal fibroblasts (HDFs) after the treatment of vitexin. The results show that oxidation of 5-(6-)chloromethyl-2',7'-dichlo-rodihydrofluorescein diacetate ($CM-H_{2}DCFDA$) is inhibited by vitexin effectively and that vitexin has a potent free radical scavenging activity in UVB-irradiated HDFs. In ROS imaging using a confocal microscope we visualized DCF fluorescence in HDFs directly. In conclusion, our findings suggest that vitexin can be effectively used for the prevention of UV-induced adverse skin reactions such as free radical production and skin cell damage.

The objective of this study is to investigate a perceived discomfort and cause of Korean elderly in various activities such as work and leisure as well as in daily activities. 120 subjects (30 female and 30 male for each age: the young and elderly) participated in the interview type of questionnaire. Each participant answered to 41 items of activities of daily living. The examination of each item was progressed with 3 steps: whether to do the activity or not, degree of activity discomfort, and the reasons or causes of discomfort. Borg's CR10 scale is used to measure the degree of discomfort of daily activities. As a result, there are differences for the proportion of performers between two age groups, except for essential activities such as individual maintenance and housekeeping. The elderly complained about their daily activities more than the young did, and the degree of discomfort of women was significantly larger than that of men with aging. There are seven items, the mean degree of discomfort of which is over three points for the elderly, and they showed significant difference between two age groups. It was the important reason that physical capacities such as muscle strength and suppleness are declined. The results showed the characteristics of Korean elderly in the whole daily activities. These will be used to understand various life styles of them and to propose a field or direction of study related to the aging.

Due to the impact of birth rate, the school age population decreases year by year, and as a result, the Ministry of Education conducts the layout adjustment for middle and primary schools and cancels substantial rural schools. Nearly half of the cancelled and idle schools are not applied till now. Combining the practical demand of local residents, it is quite necessary to make use of the idle schools effectively again. Consequently, field investigation is conducted for the architectural status of 28 idle schools in Pingle County of Guilin, Guangxi, and detail investigation and analysis has been carried out for the different scales of schools from various aspects, including the covered area, traffic, building construction, space composition, degree of aging, etc. The investigation result shows that small teaching schools are remote, being small in scale, single in space and serious in aging. Complete primary schools are close to the villages and towns, being large in scale, abundant in space, and well preserved. The teaching schools are between the previous two types. Meanwhile, it is generally convenient in traffic, and good in structure. It can provide fundamental data for the future utilization and study.

Flux-gate magnetometer was developed in 1930's, and it has been widely used for the low magnetic field measurements. In this work, we have employed amorphous ribbon 2714A produced by Allied Chem. Co. as sensor core material. To develop low noise, low power consumption, and high reliability flux-gate magnetometer, we have measured ac magnetic properties depending on the annealing conditions. As quenched state amorphous core shows high noise level and ac magnetic properties were changed under the condition of accelerated aging test, but amorphous ribbon, which was annealed under 350 $\^{C}$ during 1 hour, shows low noise level of 0.1 nT in the frequency range of dc∼10 Hz which was 10 times better than the as quenched amorphous ribbon. Under accelerated aging test, ac magnetic properties such as squareness and coercivity of the annealed samples show higher reliability and approached to a certain limiting value as exponential function. We can see that high reliability and low noise flux-gate magnetometer could be developed, if we consider this ac magnetic properties change in the sensor design.

Due to the failure of the instrument and control devices of nuclear power plants caused by aging, nuclear power plants occasionally trip. Even a trip of a single nuclear power plant (NPP) causes an extravagant economical loss and deteriorates public acceptance of nuclear power plants. Therefore, the replacement of the instrument and control devices with proper consideration of the aging effect is necessary in order to prevent the inadvertent trip. In this paper we investigated the optimal replacement periods of the control computer's components of Wolsung nuclear power plant Unit 1. We first derived mathematical models for optimal replacement periods to the digital control computer's components of Wolsung NPP Unit 1 and calculated the optimal replacement periods analytically. We compared the periods with the replacement periods currently used at Wolsung NPP Unit 1. The periods used at Wolsung is not based on mathematical analysis, but on empirical knowledge. As a consequence, the optimal replacement periods analytically obtained and those used in the field show a little difference.
