음중팔선도는 당나라 시인 두보가 유달리 술을 좋아한 여덟 명의 기이한 행동을 읊은 <음중팔선가>를 도해한 그림이다. 유달리 술을 사랑한 음중팔선은 동아시아의 지식인에게 많은 사랑을 받았고, 이들의 일화는 그림으로 표현되었다. 중국에서는 이공린 <음중팔선도>의 영향으로 두루마리에 백묘법으로 그린 음중팔선도가 유행했다. 우리나라에서도 음중팔선도는 술을 좋아하는 취객의 엉뚱한 행적과 그들이 지닌 남다른 풍류를 그린 시각물로, 혹은 영원한 우정과 무병장수를 기원하는 축수물(祝壽物)로 폭넓게 감상되었다. 기록에 따르면, 김명국의 음중팔선도는 세밀한 담채기법의 8폭 그림이었고, 정조가 어람한 음중팔선도는 8폭으로 된 채색의 대경산수인물화였다. 또한 최근 이한철의 ${\ll}$음중팔선도${\gg}$ 8폭 병풍이 소개되어 김홍도, 김양기로 이어지는 화원들의 고사인물화 제작 양상도 상상해 볼 수 있었다. 특히 음중팔선 중에서 가장 인기가 높았던 이백의 고사는 음중팔선도와 별도로 많이 그려졌고, 심지어 19세기 이후에는 고사도 병풍의 한 폭을 차지하게 되었다. 화보와 초본이 활용되면서 민간에서 비슷한 이백 고사도가 대량 생산된 것이다. 이렇듯 음중팔선도는 세상과 완전히 단절하지 않은 애주가로, 솔직하게 행동하는 풍류인으로, 술로 맺어진 영원한 우정과 무병장수를 염원하는 축수물의 주인공으로 시각화되었다. 이것이 두보의 시의도이자 팔선의 고사도인 음중팔선도가 지닌 다층적 함의라고 할 수 있다.

A theory of the school which attach great importance to moxibustion therapy was more developed from 'Ge Hong(葛洪)', 'Wang Tao(王燾)' up to "BianQueXinShu(扁鵲心書)" of 'Dou Cai(竇材)' in Song Dynasty. The first volume of "BianQueXinShu" was described about the principles of health preserving method, diagnosis, treatment related with meridian system, support Yang theory, moxibustion therapy over the 10 chapters and in the continued 3 chapters, explained the symptoms and related moxibustion therapies. The summary is as follows. The Yang energy is the essence of the human body and it is minutely explained in "Hwangdineijing(黃帝內經)". However, the younger scholars after 'Zhang Zhongjing(張仲景)' held different views with "Hwangdineijing" so they didn't control serious diseases. Supporting the Yang energy, it will be possible to human body in good health and long life and perennial youth and longevity. To do like this, the first important thing is a moxibustion, the second is a Taoist hermit medication(丹藥) and the third is well usage of Radix Aconiti Lateralis Preparata. According to the sequence of Yang energy deficiency, the stages of diseases are classified as Ordinary Gi(平氣), Latter deficient state(微虛), The more deficient state(甚虛), Exhausting state(將脫), Exhausted state(已脫) and in the consideration of each stage, it is used gradually with warm-natured berbs, warm-acrid herbs, warm-heated herbs and moxibustion therapy. If it comes to the stage of Exhausted state, the Yang energy is too weak to treat a disease. Therefore it is easy to harm human body with usage the treatment of the Purgationist school theory or the Cold and cool medical school theory, so it is needed a great attention to use these therapies. To summarized the keynote of 'Du Jae''s moxibustion therapy, the one is a minority of selection of points(1$^{\sim}$2 acupuncture points), the second is a majority of moxibustion units(50$^{\sim}$500 units), and the other is a focused selection of points on spleen and kidney(especially Gwanwon, CC4). And in this book, it was explained concretely about the size of moxibustion, according to the experiment with mentioned size, the burning time of moxibustion was almost 4 min 40 sec, so the big size moxibustion was one of the characteristic of moxibustion therapy revealed in this book. Also it was used 'Suseongsan(睡聖散)' - a kind of analgesic herb complexes - to reduce a pain during the usage of moxibustion therapy in this book. To develop the moxibustion theory, it is more investigated in the future that there wasn't significant relation between Gwanwon(CC4) and spleen and kidney meridian in theory, compared to many used Gwanwon(CC4) in the prescription, where as mentioned the importance of spleen and kidney in treatment, that considering the burning time(1 unit - 4 min 40 sec, 12 units an hour, maximum 288 units a day) there were no guidances about meals, sleeping, stool and urine, and that there was no concrete study about the toxicity of 'Suseongsan' as analgesic moxibustion therapy.

The seed of Vigna angularis has long been cultivated as a food or a folk medicine in East Asia. Genistein (4',5,7-trihydroxyisoflavone), a dietary phytoestrogen present in this plant, has been known to possess various biological properties. In this study, we investigated the possible lifespan-extending effects of genistein using Caenorhabditis elegans model system. We found that the lifespan of nematode was significantly prolonged in the presence of genistein under normal culture condition. In addition, genistein elevated the survival rate of nematode against stressful environment including heat and oxidative conditions. Further studies demonstrated that genistein-mediated increased stress tolerance of nematode could be attributed to enhanced expressions of stress resistance proteins such as superoxide dismutase (SOD-3) and heat shock protein (HSP-16.2). Moreover, we failed to find genistein-induced significant change in aging-related factors including reproduction, food intake, and growth, indicating genistein exerts longevity activity independent of affecting these factors. Genistein treatment also led to an up-regulation of locomotory ability of aged nematode, suggesting genistein affects healthspan as well as lifespan of nematode. Our results represent that genistein has beneficial effects on the lifespan of C. elegans under both of normal and stress condition via elevating expressions of stress resistance proteins.

Background: Cancer has emerged as a major health problem globally as a consequence to the increased longevity of the population, changing the environment and life style. Chemoprevention is a new and promising strategy for reducing cancer burden. Recently, some natural products have been identified for their chemopreventive activity to reduce the cancer incidence. Ginseng is known for its potential to treat various ailments in human beings. The present study was designed to explore the anticancer and antioxidative potential of Panax ginseng against chemical-induced skin carcinogenesis in mammals. Methods: Skin tumors were induced in Swiss albino mice by a single topical application of 7,12-dimethylbenz(a)anthracene ($100{\mu}g/100{\mu}L$ acetone) and, 2 wks later, promoted by repeated applications of croton oil (thrice in a wk in 1% acetone) till the end of the experiment (i.e., 16 wk). Hydroalcoholic ginseng root extract at a dose of 25 mg/kg body weight/d was orally administered at the periinitiation, postinitiation, and peri-post-initiation stages. Results: Ginseng root extract treatment caused a significant reduction in tumor incidence, cumulative number of tumors, tumor yield, and tumor burden, as compared to the 7,12-dimethylbenz(a)anthracene-croton oil-treated control group. Further, biochemical assays revealed a significant enhancement in the levels of reduced glutathione, superoxide dismutase, catalase, vitamin C, and total proteins but a significant reduction in lipid peroxidation levels in both the liver and skin with ginseng root extract treatment, as compared to carcinogen-treated control group. Conclusion: These results suggest that P. ginseng has the potential to become a pivotal chemopreventive agent that can reduce cancer in mammals.

Background: Panax ginseng has been used to prolong longevity and is believed to be useful for improving skin complexion. Ginsenosides are the most active components isolated from ginseng, and ginsenoside Rg3 (G-Rg3) in particular has been demonstrated to possess antioxidative, antitumorigenic, and anti-inflammatory properties. The aim of this study was to examine the ability of G-Rg3 to inhibit melanogenesis. Methods: The effects of G-Rg3 on melanin contents and the protein levels of tyrosinase, microphthalmia-associated transcription factor (MITF), and tyrosinase-related protein 1 (TRP1) were evaluated. Melanogenesis-regulating signaling molecules such as Akt and extracellular signal-regulated kinase (ERK) were also examined to explore G-Rg3-induced antimelanogenic mechanisms. Results: G-Rg3 was found to significantly inhibit the synthesis of melanin in normal human epidermal melanocytes and B16F10 cells in a dose-dependent manner. The activity of cellular tyrosinase and the expression of MITF, tyrosinase, and TRP1 were all reduced, whereas ERK was strongly activated. PD98059 (a specific inhibitor of ERK) attenuated the G-Rg3-induced inhibition of melanin synthesis and tyrosinase activity. Conclusion: Taken together, these results showed that G-Rg3 induces the activation of ERK, which accounts for its antimelanogenic effects. G-Rg3 may be a promising safe skin-whitening agent, adding to the long list of uses of P. ginseng for the enhancement of skin beauty.

Objectives Syndrome differentiation and treatment (辨證論治) is one of the core theories in Korean medicine and syndrome differentiation (辨證) constitutes a branch of disease diagnosis in Korean medicine. Yoon Gil-Young, one of the modern outstanding scholar of basic medical science in Korean medicine, wrote on basic theories of Korean medicine such as physiology, pathology, formula science, etc. Hereby we will analyze and discuss his works to understand his recognition of historical changes in the syndrome differentiation. Methods We conducted researches into the two works of Yoon Gil-Young's, which are "The Clinical Formula Science of Eastern Medicine (東醫臨床方劑學)" and "The theory of Four-Constitution Medicine (四象體質醫學論)". From Yoon's academic standpoint which connects the basic medical science with the clinical medicine, we analyzed his opinion about syndrome differentiation and its historical changes. Results According to Yoon's research work on syndrome differentiation and its historical changes, the development of syndrome differentiation, which goes in harmony with the history of Korean medicine, has its deep root in " Huangdi's Internal Classic (黃帝內經)" and "Treatise on Cold Damage and Miscellaneous Diseases (傷寒雜病論)". And through "Treatise on the Spleen and Stomach (脾胃論)" and the articles of warm disease (溫病論), the theory of syndrome differentiation became extended to the whole clinical diagnostic field in Korean medicine, finally including the achievements in "Treasured Mirror of Eastern Medicine (東醫寶鑑)", "Longevity and Life Preservation in Eastern Medicine (東醫壽世保元)". Conclusions Yoon Gil-Young recognized that the system of syndrome differentiation was developed in accordance with the theories from the "Treatise on Cold Damage and Miscellaneous Diseases", then the "Treatise on the Spleen and Stomach" and the articles of warm disease. The four-constitution medicine in Korea and Koho school in Japan which lays emphasis on abdominal signs also contributed to its development. Syndrome differentiation can be categorized basically into three states of intrinsic cold (本寒), intrinsic deficiency (本虛), intrinsic heat (本熱) according to the deficiency and excess in human body metabolism.

'Long-life' which has been the perennial interest to human beings also carries the risk of multiple losses such as the death of the family members and friends, the loss of physical and cognitive functions. In that regards, living a long life to be the 'oldest-old' could mean not only a 'symbol of successful aging' but also a hardship and low quality of life at the same time. Therefore, the issue of the quality of life of the oldest old has been the subject of the much of the public and research concern in recent days. While there has been increased awareness about the importance of the subjective aspects of the quality of life and meanings attached to the extended life, most researches on the quality of life of the oldest-old have focused only on the objective conditions of the quality of life such as health, economic status and housing conditions. To overcome these limitations this study aims to explore the subject meaning of 'living a long life' in Korean society by investigating centenarians and their caregivers' interpretations of aging experiences. Qualitative data were gathered from the forty-nine Korean centenarians and their caregivers through in-depth interview. Each interview was tape-recorded and transcribed verbatim. Researchers read each transcript a number of times to get some emerging themes. Most striking result was the fact that most of the centenarians express the 'guilty feelings' and try to offer the 'excuses' about their long life. This results were quite contrary to the results of the studies, done in Japan and western countries like Sweden, United States and Germany, where most of the oldest-old express quite positive interpretations about their long-life and take pride in their longevity. Lack of social support, cohort characteristics of the Korean oldest-old and the cultural interpretations linking the death of children to the long life of older generation are given as possible factors to these unique findings of Korean study. The policy implications of the results are discussed.

As longevity of human-beings is extended and the population of aged people increases, diverse issues related with the aged people are presented. The neighborhood space for the aged people is required to be designed based upon the understanding of such difficulties of the elderly and the public outdoor environment is an important environmental resource that can enhance the quality of life and promote the health of the elderly in underprivileged area without burdening them economically. This study aims to research the daily life of the elderly in underprivileged urban area and their utilization styles of outdoor environments in order to find out the push factors and pull factors that induce the aged people to use the outdoor environments. For this purpose, this study carried out an interview survey upon 69 elderly residents and surveyed on 363 elderly residents of low income class who are aged 60 and over and living in decaying area in Jeonju. For the analysis of the collected data, a qualitative and a quantitative analysis were accomplished. As results of study, the elderly in underprivileged area use such outdoor environments as resting facilities, exercise equipment, parks, farming gardens and waterfronts, and the push factors for them to use the outdoor environments were sordid indoor spaces, sense of isolation or loneliness, and the desire for maintaining good health. And the pull factors for them to use the outdoor environments were natural factors, opportunities for social interactions, space for exercise. The obstacles that hinder the elderly in using outdoor environments were the bad health of the elderly, lack of facilities, accessibility and weather conditions. Thus, the results of this study are expected to provide basic data for designing the outdoor environments to promote the health of the elderly in urban underprivileged area and to relieve the burdensome problems related with ageing societies.
