In the evaluation of aging degradation on the structural materials based on the fracture mechanics, the detection and size prediction of defect are very important. Aiming at nondestructive detection and size prediction ol defect with high accuracy and resolution, therefore, an lnduced Current Focusing Potential Drop(ICFPD) technique has been developed. The principle of this technique is to induce a focusing current at an exploratory region by an induction wire flowing an alternating current(AC) that is a constant ampere and frequency. Defects are assessed with the potential drops that are measured the induced current on the surface of metallic material by the potential pick-up pins. In this study, the lCFPD technique was applied for evaluating the location and size of the surface crack and blind crack made in plate specimens, and also for detecting the defects existing in valve, a field component, that were developed by SCC etc. during the service. The results of this present study show that surface crack and blind crack are able to defect with potential drop. these cracks are distinguished with the distribution of potential drop, and the crack depths can be estimated with each normalized potential drop that are parameters estimating the depth of each type crack. In the field component, the defects estimated by experiment result correspond with those in the cutting face of the measuring point within a higher sensitivity.

In recent years, there has been increasing interest in the senior people in our aging society. This paper will give an account of the current cases of senior shift. The first section of this paper will examine a conceptual approach based on a literature review and analyze case studies of senior shifts by national fashion and beauty brands. It will be helpful for the 'New Senior' consumer group, which in emerging in an aging society. The research methods applied were a literature review and a case study, and a database search was conducted to determine the current situation of global brands. The results of the literature review showed that seniors can be classified into four types based on their physical aging condition and emotional tendency: Prime Senior, Smart Senior, Rational Senior, and Slump Senior. The first thing that needs to be said is that the Prime Senior type is found commonly in as a way to appoint a senior model in order to switch brand image. Cases of the Smart Senior type appeared only in the beauty field, which attempted multilateral approaches such as launching products exclusively for seniors and offering make-up services after improving the usability and functionality in response to senior consumers'needs. However, as no cases of senior shift were found for the Rational Senior and Slump Senior types in either the fashion or beauty field, future studies should explore the market approaches used in those categories.

The effects of additives (Cr, Nb, Dy, and Bi) on microstructure, electrical properties, dielectric characteristics, and aging behavior of $ZnO-V_2O_5-MnO_2-Co_3O_4-La_2O_3$ (ZVMCL) ceramics were systematically investigated. The phase formed in common for all ZVMCL ceramics modified with various additives consisted of ZnO grain as a main phase, and $Zn_3(VO_4)_2$ and $ZnV_2O_4$ as the secondary phases. The sintered density and average grain size were in the range of $5.4-5.54g/cm^3$ and $3.7-5.1{\mu}m$, respectively. The ZVMCL ceramics modified with Cr exhibited the highest breakdown field (6,386 V/cm) and the ZVMCL ceramics modified with Nb exhibited the lowest breakdown field (3,517 V/cm). All additives enhanced the nonlinear coefficient (${\alpha}$), by a small or large margin, in particular, additives such as Bi and Nb noticeably increased the nonlinear coefficient, with ${\alpha}=25.5$ and ${\alpha}=23$, respectively. However, on the whole, all additives did not improve the stability against a DC stress, compared with ZVMCL ceramics.

As Korea's representative medical text, "Donguibogam" reveals Korean Medicine's unique perspective on the human body. The text also contains abundant resources related to skin, leading to diverse researches on the subject today. In this paper, authors tried to elicit values of "Donguibogam" in the general cosmetics field, through literature review. First, prescriptions related to main functions of modern cosmetics (anti-aging, whitening, and moisturizing) were classified. In relation to anti-aging, concepts such as 返老 (reversing aging), 還童 (to become young again), 皺 (wrinkle), and 皮急 (tense skin) were extracted and 69 examples of treatments were introduced. For whitening care, 41 treatments were mentioned on hyper-pigmentation and general complexion. Concepts related to moisturizing included expressions such as 潤肌膚 (hydration of skin) and 光澤 (glow), induced by 48 treatment prescriptions. Second, cosmetics related prescriptions were classified according to the application methods of modern cosmetics. 78 prescriptions of cleansing category included washing-off local area with herbal liquid, bathing, washing-off after steaming, and soaking the body in the herbal liquid. Total of 308 topical application prescriptions covered the conditions of various skin inflammations, scalp illnesses, and etc. In conclusion, this research examines the value of "Donguibogam" as a useful of skincare.

This study examines the effects of the Korean horticultural foods which are, by traditional wisdom, supposed to contain anti-aging substance. All twenty three kinds of plants are chosen as a sample for the experiment in which the content of three main anti-aging nutrients, -carotene, Vitamin C, and Vitamin E are respectively measured by Nilis, Colorimetric, and AOAC method. The result shows: among the samples, top six plants that contain the most -carotene content are high quality tea(Camellia sinensis), thistle(Cirsium japonicum Var.), Angelica keiskei, mulberry leaves(Morus alba l.), field horsetail(Equisetum arvensa), and carrot(Daucus carota), in order; top four for a Vitamin C contents are low quality tea, mulberry leaves, pine leaves(Pinus densiflora), and high quality tea, in order; top four for a Vitamin E contents are persimmon leaves(Diospyros mongolicum) tea, high quality tea, low quality tea, and pine leaves, in order. Drying or boiling process increases the content of -carotene and Vitamin E in high quality tea, dropwort(Oenanthe javanica), field horsetail, and wild aster(Ligularia stenocephala Marsumum et Koldzumi), while, in case of mulberry leaves, drying process lowers them. Vitamin C content strikingly decreases in heating and drying process.

This paper seeks to interrogate the very assumption of "sociality" in social media at a conceptual level and substantiate it with the help of information collected on aged people's use of conventional media $vis-{\grave{a}}-vis$ so called "social media" from the field work. Although global literature has written the obituary of mass media and promoted the "sociality" of social media, one needs to critically engage with such statement. Such statements have been an outcome of the established status of the "post broadcast" model of media where conventional media is in existence for some time and accessible to everyone in society. Further, this paper seeks to explore the interplay of new media in the life of the aged population in select areas of Kolkata city in the state of West Bengal, India. There are few studies on the ageing population's use of new media in the Indian context. While many of the studies reveal the new media literacy among the youth, this is unimportant as both the new media and the youth are relatively young as a field of research in media studies in India. What is missed in the earlier studies is, how new media plays an important function in the life of the aged population. How do older adults engage with the skilling and deskilling process of media literacy in their everyday life? And finally, do new media provide an extension to their on-going social relations? With the help of substantive details, the present study addresses the aforementioned queries.

Recently, new aspects of paints such as a beautiful appearance, use of environmentally friendly paints, etc., in addition to the superior performance of paints have been requested for industrial paints including the paints for heavy construction equipment and others. Particularly, the quality of appearance of coating affects the sales of heavy construction equipment. And the necessity for the paints to have a superior weather-proof property without changing the luster or color even after long-time exposure to the open air is emphasized. The change in the surface color and luster of the paint due to the natural environment progresses very slowly, and it takes a long time to verify material properties when developing new paints. In order to improve such methods, weathering tests are performed in many laboratories as a test for accelerating aging of coating, and the lifetime of the products is estimated through evaluation of the weathering (environment-proof) quality of paints. However, not a great deal of research activity has been conducted up to the present time since the interrelationship between the actual results of testing and field data is different for each paint and it takes a long time to study relevant materials. Therefore, introduced in the present study is the estimation of the change in the quality of appearance of coating in the field through the accelerated aging test among the cases of improvement of the quality of appearance of the urethane paint for heavy construction equipment.

현재 우리나라에서 운영 중인 교량 중 30년 이상 된 교량이 전체의 약 11%를 차지할 정도로 노후교량의 수가 증가하고 있다. 따라서 교량의 노후화에 따른 영향을 고려한 내진성능 평가방법의 개발이 필요하다고 볼 수 있다. 예제 교량으로는 포트받침, 탄성고무받침과 납-고무받침을 가진 3가지의 강합성 상자형 거더교를 선정하고, opensees 프로그램을 사용하여 구조해석모델을 작성하였다. 본 연구에서는 교량의 노후도를 교각의 주철근과 띠철근의 부식에 의한 면적의 감소로 반영하였다. 교각의 노후화 정도로는 5%, 10%, 25%, 50%의 4가지 조건을 사용하였다. 입력지진으로는 근거리 지진과 원거리 지진을 각각 40개씩 사용하였으며, 노후화 정도에 따른 예제교량의 교각에 대한 최대변위와 최대 전단력 응답을 구하여 비교하였다. 노후도가 증가할수록 힘-변위 관계에서 교각의 강도 저하가 발생함을 알 수 있으며, 이로 인하여 교각의 변위응답이 증가함을 알 수 있다. 교각의 노후도에 따른 변위응답과 전단저항능력의 영향을 분석하기 위하여 변위비(D_ratio)와 전단력비(F_ratio)를 정의하여 평가하였다. 예제교량의 고유주기가 길어질수록 노후도에 따른 변위비(D_ratio)의 증가가 크게 나타남을 알 수 있으며, 전단력비(F_ratio)의 감소 경향은 작게 나타남을 알 수 있다.
