The temperature and the grain boundary precipitation have the great influence on the low-cycle fatigue behavior of austenite stainless steel at elevated temperature. For the purpose of investigating the mechanism concerning the change of fatigue micro crack mode in SUS 316 under various conditions low-cycle fatigue test was carried out at the elevated temperature 600.deg.C, plastic strain range 2% and constant strain rate .5c.p.m. A special attention is given to the observation of intergranular crack initiation. The results obtained are summarized as follows. The low-cycle fatigue behavior of SUS 316 at 600.deg.C is affected by transition of crack initiation mode from intergranular to transgranular. The transition is due to the aging effect, which is caused by grain boundary precipitations of Cr$\_$23/C$\_$6/. Since the intergranular crack initiation is brought about by the grain boundary sliding, the transgranular crack initiates in case that the strengthening of grain boundary due to the precipitation of Cr$\_$23/C$\_$6/ carbides takes place ahead of the intergranular crack initiation.

COVID-19가 전 세계를 휩쓸면서 지금까지만 해도 4,500만명 이상의 확진자와 100만 명이 넘는 사망자가 발생했고, 당분간 이런 상황이 계속될 것으로 보인다. 특히 이탈리아나 스페인 등을 비롯한 유럽의 경우에는 감염자의 절반 이상이 요양시설에서 발생했고, 미국에서도 노인요양시설에서 4천여 명이 사망한 것으로 보고되고 있다. 때문에 포스트코로나 이후에 당면하게 될 문제는 집단돌봄에 대한 근본적 해결 요구와 가정 중심 서비스로의 이동에 있게 될 것이다. 특히 ICT 등 4차 산업 기술을 접목한 가정중심돌봄, 즉 초 기술을 기반으로 하는 커뮤니티 케어의 정착과 확장에 관한 논의가 점점 더 활발해질 것으로 보인다. 이로 인하여 4차 산업과 사회보장·사회복지를 어떻게 구체적으로 결합할 것인가라는 과제가 주어진다. 이른바 스마트웰페어시티를 어떻게 만들어 국민의 사회보장과 복지에 기여할 것인가가 바로 그것이라고 할 것이다. 이러한 상황에서 본 논문은 선행연구에서 다루었던 사회보장플랫폼에 관한 내용 중 그 기능과 범위 및 스마트웰페어시티 개념의 확정과 확장가능성을 통해 비대면 돌봄의 개념과 범위 및 내용 등을 고찰하였다. 이는 우리 사회가 지향하고자 하는 사회보장·사회복지영역에서의 스마트시티를 구현함으로써 커뮤니티 케어나 Aging in Place를 실현하고자 하는데 나름의 중요한 의미를 가지는 것이라고 판단된다. 다만 비대면 돌봄서비스의 구현을 위한 정책적, 법·제도적 관점에서의 구체적 방안이 무엇인지에 대해 다루지 못하고 있는 점은 아쉬운 부분이며 향후 이에 대한 연구가 필요하다는 점에서 한계가 있음을 밝혀둔다. 본고에서 다루고 있는 내용들이 스마트웰페어시티 뿐 아니라 행정·실천·법제 등을 비롯한 사회보장·사회복지체제 내지 전달체계 등에서의 방향과 미래상을 제시하고, 궁극적으로는 인간의 삶의 질 향상이라는 목표를 달성하는데 기여할 수 있기를 기대해 본다.

Background and Objective : Increasing interest in anti-aging and anti-wrinkling agents for the skin has triggered the recent outflow of researches and studies in this field. This study was designed to investigate the effects of bee venom on skin wrinkling and skin aging by testing the skin wrinkling, skin elasticity, trans-epidermal water loss (TEWL), free radical level, anti-oxidative agent level, and skin tissue after infusion of bee venom on hairless mouse. Materials and Methods : Fifteen hairless mice aged between 36~40 weeks were divided randomly into 3 Group; the Bee Venom Syringe Group, the Bee Venom Needle Group, and the control group. The Bee Venom Syringe Group were injected subcutaneously with bee venom (0.1cc in total) using an insulin syringe on three spots in the lumbar spine (one spot on the center and two spots 1~2cm to the side bilaterally). The Bee Venom Needle Group were pricked with bee venom-smeared acupuncture needles on three longitudinal spots in the lumbar spine each 1cm apart, after which the needles were removed 10 minutes later. The Control Group did not receive any form of intervention. All procedures took place thrice a week for four weeks, during which the mice were allowed free access to water and fodder. The mice were measured and compared in the weight, skin wrinkling scale, skin elasticity, and TEWL before and after the experiment. After the experiment, blood samples were taken to measure the free radical and anti-oxidative agent level, and the skin tissue was sliced for examination. Data was analyzed using the SPSS program (ver 12.0). The ANOVA analysis was used to compare and contrast the three groups, and t-test for paired samples was used to evaluate skin-wrinkling before and after experiment. The cut-off p-value of significance was set at p<0.05. Results : 1. Administration of bee venom did not cause serious weight loss or gain. 2. Compared to the control group, the Bee Venom Syringe Group and the Bee Venom Needle Group both showed a decrease in skin wrinkling scale after intervention. Especially, the Bee Venom Syringe Group showed a significant decrease (p<0.05). 3. Compared to the control group, the Bee Venom Syringe Group and the Bee Venom Needle Group both showed an increase in skin elasticity. Especially, the Bee Venom Syringe Group showed a significant increase (p<0.05). 4. No significant change in TEWL was found in the mice in all the three groups before and after experiment. 5. Free radical level was normal in all 15 mice in all the three groups, and anti-oxidative agent was not significantly different across the three groups. 6. The Bee Venom Syringe Group, the Bee Venom Needle Group, and the control group did not show any significant difference in the thickness of epidermis and dermis, infiltration of inflammatory cells, and skin wrinkling. The epidermis layer was relatively better preserved in the Bee Venom Syringe Group as compared to the Bee Venom Needle Group and the control group. Conclusion : Direct injection of bee venom on the hairless mouse using a syringe was found to improve wrinkling of the skin and increase skin elasticity but did not show effectiveness on skin dryness due to water loss. The bee venom appears to have suppressive effects on skin wrinkling, one of the symptoms of skin aging, through a process independent of suppression of free radicals or increase of anti-oxidative agent.

The officetel introduced into Korea in the mid-1980s has thus far been in the limelight as the object of investment for the substitute for small-sized housing and for lease income. But to raise the possibility of succeeding in officetel investment in the future, it has been necessary to make a systematic analysis of the changed direction of the officetel market and the profitability and stability of investment. Accordingly, this study attempted to analyze demand for officetel with a focus on the possibility of increase in the households composed of one or two members, the major consuming bracket of small-sized housing. And it attempted to analyze the possibility of investment in officetel as the investment goods for lease income due to the entry of Korea into aging society. And past analysis of investment in officetel was confined to profitability analysis, but this study sought to develop the stability indicator of the officetel for the analytical purpose. As a result, it is predicted that demand for small-sized housing will increase due to the increase in 1-to 2-person households. Accordingly, it is predicted that demand for officetel as the place of residence will come to increase. And taking into consideration the more serious degree of sustained aging in the population, older people's preference for real estate and need for lease income, it is predicted that preference for officetel as the object of investment will increase. An attempt was made to analyze the profitability and stability of investment in the metropolitan area which the officetel has principally been supplied, in order to analyze the profitability and stability of officetels. For the purpose of this study, Yeoksam-dong in Kangnam-gu, Yeoui-dong in Youngdeungpo-gu, Bongcheon-dong in Kwanak-gu were selected in Seoul as the area for analysis. Jung-dong in Wonmi-gu, Bucheon, Seohyun-dong in Bundang-gu, Seongnam, Janghang-dong in Ilsan-gu, Koyang were selected in Kyonggi province as the area for analysis. As a result, it was found that the small-sized officetel had higher profitability and stability than the large-sized officetel. It was found that the area of Kyonggi Province had the larger deviation by size. That is, it was found that the small-sized officetel in the area of Kyonggi Province was significant as the object of investment for stable lease income.

This study adopts the phenomenological approach in order to explore the experience of urinary felt by the small island women and to find the meaning and structure of their experience, for the further understanding of them. This study succeeded in detecting five topics and three basic structure from eight participants, and followings are the comprehensive statement of them. The five topics include neglect of care after childbirth, unavoidable life in the tidal flat, shame which cannot be expressed even to their husbands, endless anxiety toward the expected future, and sad(dilemmatic) lived experience. The basic structure is that small island women who have urinary incontinence are apt to regard their disease as a natural destiny of women who fail to get adequate care after childbirth, and something to be endured to live in the seashore. They think of urinary incontinence as something so shameful that they cannot reveal it even to their husband and family. They believe that it even changes their personality since they must always stay alert in order to cope with the situation; for example, when it takes place unexpectedly, like too often to go to toilet, to change the underwears, to wake up in the middle of the night to go to toilet, to try not to laugh loudly, or to have showers. In addition, they accept it as a natural process of aging and incurable disease, and they consider themselves already ruined on the way of becoming uglier. They show dilemmatic abandonment: give it up unwillingly but at the same time think it is natural for others too. The unique experience of small island women with urinary incontinence implied in those statement are inseparable with the specific conditions for survival in the island. Unlike other diseases, it is considered the result of traditionally poor care after childbirth. However this misunderstanding that it is a natural phenomena for all the women who experience childbirth and aging and thereby incurable leads to an undesirable attitude toward urinary incontinence. According to the analysis, environmental conditions specific for small islands make the women there have distinct and unique experience concerned with urinary incontinence. Consequently, the future nursing plan for urinary incontinence in the small island area must be made and enforced with the consideration of these specific phenomenological meanings. Modern Korean nursing has basically been centered to hospital or urban areas. Besides, nursing intervention has long depended upon the research of western countries. This research, however, shows how greatly the regional and cultural characteristics influence the understanding of a certain disease, and is expected to make more specific and in-depth nursing approach enable for those who have urinary incontinence in small islands.

Subject : The Association between Extraordinary Organs(奇恒之腑) and Eight Extra Meridians(奇經 八脈). Objectives : This study research some special aspects of Extraordinary Organs and Eight Extra Meridians which differentiated from ordinary Organs and Meridians, and the association between Extraordinary Organs and Eight Extra Meridians. Methods : First, researched classification standard and physiological characteristics of Extraordinary Organs through studying various chapters of HuangdiNeijing. Second, researched The Association between Extraordinary Organs and Eight Extra Meridians through studying on the origin of Eight Extra Meridians in HuangdiNeijing. Third, from accompanying researching the subject of Cheon-gye(天癸) and human body shape, draw synthetic hypothesis on the relationship among ordinary Meridians and Organs, muscles and skins of body shape, Extraordinary Organs and Eight Extra Meridians. Results & Conclusions : The following conclusions could be drawn. 1. Extraordinary Organs afford background for shaping human body. This is same as the properties of the earth which afford background for shaping all creations. The physiological characteristics of Extraordinary Organs is intermediation and regulation between Ki(氣) of Five Viscera & six Bowels and shape of muscles & skins in human body. 2. The origin of Eight Extra Meridians could be found in HuangdiNeijing. The collateral Meridians of the Uterus and Epiglottis Meridian are specifically formulated to supplying for the Uterus or Epiglottis. From this we can draw The Association between Extraordinary Organs and Eight Extra Meridians, that is Eight Extra Meridians are specifically formulated to supplying for Extraordinary Organs. 3. The Cheon-gye(天癸) is doing significant function in Eight Extra Meridians supplying for Extraordinary Organs. Cheon-gye concerned to growth, secondary sexual characters, generative function, aging process. Theses are all concerned with the changing of human body shape. Cheon-gye urge to change the body shape with following the human life cycle. 4. Human body has vertical symmetry because preserve its shape from the gravitational force. Eight Extra Meridians place at the middle or flank axis of human body, thus do physiological function that assistant human body have vertical symmetry shape. The purpose of shaping vertical symmetry is securing space what the inner Twelve Regular Meridians and Five Viscera & six Bowels create there own physical changes. On the other hand the inner changes need deviation between left and right because of mobility and circulation of force. But human body change the shape in the process of growth, reproduction, aging. Eight Extra Meridians play role at time of these processing, thus they deeply concerned to human's life cycle and reproduction. 5. Eight Extra Meridians and Extraordinary Organs were named 'Extra' because of some special aspects which differentiated from ordinary Meridians and Organs. All they play role to have vertical symmetry shape of human body and maintain the shape, thus they deeply concerned to the change of human life cycle. These shaping maintaining and the change of human life cycle are very special aspects of human body. So they needed to differently cognize separate to the ordinary changes of Five Viscera & six Bowels and Twelve Meridians at inner space.

Various health and social issues related to the elderly are emerging in line with the rapid aging of the population. In particular, dementia currently has a prevalence of about 10 percent of the elderly population in South Korea, which increases financial and social burdens to not only individual patients but also their caring family. To assess the effects of participating in the forest therapy programs for dementia prevention, this study recruited participants aged 50 and above and tested their depression (Korean form of Geriatric Depression Scale; KGDS) and stress response (Modified form of Stress Response Inventory; SRI-MF), which are emotional aspects of dementia. As a result, KGDS showed a significant decrease of 3.2 points from 8.4 to 5.2 points, and SRI-MF showed a significant decrease of 7.2 points from 40 to 32.8 points, indicating a statistically significant improvement in both. In addition, participants with minor depression and high level of stress in the pretest showed statistically significant improvements in the SRI-MF for men, and the KGDS and SRI-MF for women. Furthermore, there were statistically significant improvements in KGDS for participants in their 60s and in SRI-MF for those in their 70s in terms of age, and in both KGDS and SRI-MF for participants with chronic diseases and in KGDS for participants without chronic diseases. This study confirmed the effects of forest therapy on the prevention of the emotional aspects of dementia and laid the groundwork for increasing the applicability of forest therapy by obtaining a place for dementia prevention as a field of forest therapy.
