Objective : This study was to investigate the effects of several herbs on the levels of MT1 and MT2 melatonin receptorsMethods : For this study, we carried out dementia assessment examination of 34 patients with memory disturbance who have come to Cheongju oriental hospital of Daejeon university from April 2005 to February 2006. This study classified the patients as none-dementia(ND), questionable dementia(QD), and dementia(DA) groups and analyzed the result of examination. Results : 1. The water extracts of Dimocarpus long (WEDL) induced the levels of MT2 melatonin receptor expression in a concentration-dependent manner without altering the levels of MT1 melatonin receptor expression. 2. The treatment with the water extract of Zizyphus vulgaris (WEZV) induced the levels of MT1 melatonin receptor expression and the levels of MT2 melatonin receptor expression was not affected. 3. The levels of MT1 as well as MT2 melatonin receptor expression were markedly up-regulated in the water extract of Fossilia ossis (WEFO) and the water extract of Ostreae caro (WEOC)-treated C6 cells. 4. The combination treatment with WEDL and WEZV induced not only the levels of MT1 melatonin receptor expression but also MT2 melatonin receptor expression, but the synergic effects of the combination treatment with WEFO and WEOC were not detected in C6 cells. Conclusion : The study provides important new insights into the possible mechanisms on the regulation of melatonin receptor synthesis by WEDL, WEZV, WEFO and WEOC.

A pitch coating method was proposed for the purpose of improving the electrochemical properties of natural graphite. The synthesis conditions of pitch coating were optimized via measuring electrochemical properties of pitch-coated graphite anodes. As the synthesis temperature increased, the thermal stability was improved in addition to an increase in the softening point and residual carbon weight. However, the synthesis temperature of 430 ℃ resulted in the synthesis of a large amount of NI (NMP Insoluble) due to excessive condensation reaction. As the surface uniformity and coating thickness increased due to high thermal stability, the initial coulombic efficiency and rate capability of the pitch-coated graphite were improved. However, the graphite coated with the pitch containing excessive NI showed lower electrochemical properties than the uncoated graphite. NI had low dispersibility and formed spheres after heat treatment, so it formed the heterogeneous and thicker SEI layer. The optimum conditions for forming a uniform surface and an appropriate coating layer were investigated.

김보라,신우석,김영기,Kim, Bo-Ra,Shin, Woo-Seok,Kim, Young-Kee 한국공업화학회 2015 공업화학 Vol.26 No.4

본 연구에서는 제주도에서 채집한 Hizikia fusiformis biochar를 이용하여 수용액 상에서 $Cr^{6+}$과 $As^{3+}$ 중금속의 흡착 특성을 평가하였다. $Cr^{6+}$과 $As^{3+}$ 흡착에 있어서 최적 pH는 각각 pH 2와 pH 6이었다. 동역학적 실험 결과, 대부분의 중금속이 처음 100 min 동안 흡착이 되었으며, 300 min 이후 평형에 도달하였다. 또한, 해초 biochar의 $Cr^{6+}$과 $As^{3+}$ 중금속 흡착은 유사 1차 모델과 2차 모델에서 모두 잘 부합하고 있는 것으로 나타났다. 평형 흡착 실험 결과는 Langmuir 모델에 잘 부합했고, $Cr^{6+}$ (25.91 mg/g)이 $As^{3+}$ (16.54 mg/g)보다 흡착량이 높았다. 본 연구 결과를 통해, 오염된 환경에서 해초 biochar는 $Cr^{6+}$ 및 $As^{3+}$ 중금속의 효과적인 흡착제임을 보였다. This study examined the adsorption characteristics of $Cr^{6+}$ and $As^{3+}$ in the aqueous solution by Hizikia susiformis biochar which was collected from Jeju Island. The optimal pH for $Cr^{6+}$ and $As^{3+}$ adsorption were 2 and pH 6, respectively. Kinetic data showed that the adsorption occurred during the first 100 min, and the most of heavy metals were bound to biochars within 300 min. Moreover, the kinetic data presented that the course of adsorption follows the Pseudo first and second order models. The equilibrium data were well fitted by the Langmuir model and the $Cr^{6+}$ adsorption capacity (25.91 mg/g) was higher than that of $As^{3+}$ (16.54 mg/g). From these results, the seaweed biochar was shown to be a efficient adsorbent for $Cr^{6+}$ and $As^{3+}$ metals in a contaminated environment.

본 연구는 기혼 중년 남성의 갱년기 증상이 자살 사고에 미치는 영향에서 주관적 행복감의 매개효과를 파악한 연구이다. 자료수집은 2020년 12월부터 2021년 1월까지 실시하였으며 인터넷 커뮤니티를 통해서 설문 응답에 자발적으로 참여한 기혼 중년 남성을 대상으로 하였다. 최종 연구 대상자는 갱년기 증상이 있는 199명의 기혼 중년 남성이었다. 기혼 중년 남성의 갱년기 증상, 자살 사고 및 주관적 행복감은 유의한 상관관계가 있었으며, 갱년기 증상과 자살 사고의 관계에서 주관적 행복감은 매개효과가 있는 것으로 나타났다. 본 연구의 결과로 갱년기 남성의 주관적 행복감을 향상시키는 것이 자살 사고를 예방하는데 도움이 될 수 있음을 확인하였다. 따라서 연구자는 본 연구 결과를 토대로 추후 갱년기 남성의 자살 사고를 예방하는 간호중재 방안을 마련하여 그 효과를 확인해 볼 것을 제언한다. This study was to investigate the mediating effect of subjective happiness on the effect of andropause symptoms on suicidal Ideation in married middle-aged men. Final Participants were 199 married middle-aged men with andropause symptoms. Andropause symptoms, suicidal ideation, and subjective happiness of middle-aged men showed significant correlations. The mediating effect of subjective happiness on the relationship between andropause symptoms and suicidal ideation was verified. The findings revealed that an improving subjective happiness of men with andropause symptoms can be helpful for the prevention of suicidal ideation. Therefore, the researchers suggest that future researchers develop nursing interventions for the prevention of suicide ideation of men with andropause symptoms based on the results of the study, and evaluate its' effects.

Dynamic range on the digital detector can be a representation to the ratio of maximum and minimum of pixel value. Wide dynamic range and post processing ability of the digital detector made difficult to recognize visually to high or low dose images. We were evaluated a change of mean pixel value on the original and processed image, when we controlled the kVp, mA, exposure time on the digital detector. On the kVp of a constant condition, we were acquired an original and processed image by changes of mA, exposure time. According to the thickness of the subject under the same conditions, to determine a relation of pixel value and X-ray intensity, we used an aluminum step wedge. When mA and exposure times were changed under the kVp of a constant condition, the X-ray intensity was decreased by the reduction of the mean pixel value. In addition when kVp was increased in a constant condition of mAs, the mean pixel value was increased according to the increment of the X-ray intensity. Therefore, low kVp, high mA and short exposure time were a way to reduce a patient dose.

게르하르트 리히터의 자본주의 리얼리즘 연구

김보라 ( Bo Ra Kim ) 한국기초조형학회 2014 기초조형학연구 Vol.15 No.5

1963년 게르하르트 리히터는 콘라트 루엑, 지그마 폴케, 만프레트 쿠트너와 함께 ‘독일의 팝아트’라 불리는 자본주의 리얼리즘 그룹을 결성했다. 이는 동독의 사회주의 리얼리즘에 대응하는 개념이었으며 당시 서독 사회에서 급속하게 성장하고 있던 소비문화와 매체환경에 대한 젊은 예술가들의 반응이었다. 미국 팝아트와 더불어 당시 뒤셀도르프와 라인란트 지역을 중심으로 전개된 플럭서스 운동의 영향을 받았던 자본주의 리얼리즘 예술가들은 정육점이나 가구 상점, 뜰 같은 기존 미술 제도를 벗어난 공간에서 해프닝과 전시 작업을 선보였다. 자본주의 리얼리즘 그룹은 미국 팝아트와 유사하게 소비사회를 반영하는 광고 이미지나 아마추어 사진을 활용한다. 그러나 미국 팝아트에서 일반적으로 보이는 낙관주의나 유머와 달리 자본주의에 양가적 입장을 보인다. 그들은 자본주의의 해방적 잠재력을 인식했고 예술가인 자신을 소개하고 경력을 알리기 위해 자본주의 광고 전략을 의식적으로 사용했던 동시에, 다른 한편으로 대중매체와 사진 복제 이미지를 통해 자본주의의 상투성과 역사의 문제를 비판적으로 제시했다. 이 논문은 작가 인터뷰, 아티스트 스테이트먼트, 비평문, 전시도록 등 다양한 문헌자료를 통해 자본주의 리얼리즘의 형성배경과 전개과정을 확인한다. 이로써 리히터의 초기 작업을 조명하고, 이것이 그의 작 Gerhard Richter, Konrad Lueg, Sigmar Polke and Manfred Kuttner founded Capitalist Realism, so called ``German Pop Art``, in 1963. This term is the counterpart of Socialist Realism of East Germany and implies young artists` responses to rapidly growing consumer culture and mass media environment in West Germany. The Capitalist Realism was influenced by American Pop Art, and Fluxus movement in Dusseldorf and Rheinl and, West Germany. Capitalist Realists featured and staged their works and happenings in non-institutional space, for instance butcher shop, furniture store and yard. They used advertisement images and amateur photographs as American Pop Artists did. However, contrary to optimism and humor of American Pop Artists, these artists had an ambivalent attitude to the capitalism. They perceived its emancipatory potential and consciously used capitalist`s advertising strategies in order to present themselves as artists as well as to promote their own careers, while pointing out capitalism`s banality and historical problem with the help of mass media and reproduction images. This essay will examine the social and cultural backgrounds and development of Capitalist Realism with various references(interviews, artist statement, articles, catalogues, etc.). This process aims at throwing new light on Gerhard Richter`s early work and looking into its relevance to his oeuvre.
