알베도는 지구 복사균형을 이루는 요소 중에서 지표의 에너지 균형에 직접적으로 영향을 주는 인자로 알려져 있다. 이러한 알베도 변화는 토양 수분량, 식생, 태양광의 입사 각도, 적설 등의 변화를 포함하여 지구 복사균형과 그것이 기후와 식생 변화에 미치는 영향력을 이해할 수 있는 결정적인 변수로 작용한다. 따라서 알베도 변화 모니터링은 기후 변화 예측에서 필요한 과정 중 하나이다. 본 연구에서는 동북아시아의 알베도 변화를 관측하기 위하여 2001년부터 2011년의 MODIS Albedo 16-Day 자료를 이용하였다. 연간알베도 변화에서 식생이 활발한 토지피복의 알베도 값이 NIR 밴드에서 높은 알베도 값을 VIS 밴드에서 낮은 알베도 값을 가짐을 확인하였고, 2002년을 기준으로 고비사막 부근과 만주지역의 알베도 값이 변화를 보여 식생 변화 지역으로 사료되어 세부 연구영역으로 선정하였다. 또한 최솟값의 변화로 두 지역 모두 2010년 이후 식생이 악화됨을 감지할 수 있었다. Albedo is known as a factor that directly impacts on the surface energy balance one of the elements of earth radiation balance. The change of albedo includes the change of soil moisture, vegetation, solar zenith angle, snow, and so on. In addition, it operates as a crucial path to understanding feedback mechanisms between radiation balance and its influence on climate and vegetation dynamics and therefore, observing the variation of albedo is a one of the essential procedures for anticipating climate change. In this study, we used MODIS 16-Day composited Albedo data from 2001 to 2011 years with the purpose of observing the change of albedo over Northeast Asia. According to the tendency of albedo for 11 years, albedo in the area of an active vegetation has increased in near-infrared (NIR) domain and decreased in visible (VIS) domain. On the basis of local changes in vegetation in 2002, the both area of the Gobi Desert and the Manchuria was enormously changed and chosen the research area and furthermore, the vegetation of both regions had deteriorated due to the change of the minimum value since 2010.

For more effective intraperitoneal chemotherapy, the authers made 5-fluorouracil-polyglycolic acid composite disks(FU-PGA disks) with 5-fluorouracil and polyglycolic acid, a biodegradable polymer. We inserted the FU-PGA disk into the peritoneal cavites of Sprague-Dawley male rats, the control and three experimental groups; one FU-PGA disk insert group(300mg/kg), two FU-PGA disk insert group(600mg/kg), and three FU-PGA disk insert group(900mg/kg). The control group received a similar number of PGA disk inserts. A pharmacokinetic study was performed to measure the 5-fluorouracil concentration in the peritoneal fluid, blood, and tissues(liver, kidney and heart) at 24 hours, 72hours and 168 hours after insertion of the FU-PGA disk. Light and electron microscopic studies were done. The results were as follows: 1) The number of white blood cells and platelets decreased after FU-PGA insertion. The degree was proportional to the duration and amounts inserted. The change in the number of red blood cells varied slightly. 2) Light microscopically, slight changes were noted at 168 hours in the 3 disk insert group (900mg/kg). Mild fatty change and hepatocyte degeneration around the central veins of the liver were noted, with vacuolar degeneration in the proximal convoluted tubules of the kidney. 3) Electron microscopically,the liver showed focal increases of lipid droplets in the hepatocytes, and irregular nuclear membrane with focal nucleolar segregation of the fibrillar and granular elements. Also the double membranous structure of the hepatocytes and Kupffer cells was widened with bleb formation. The kidney showed wide separation of the nuclear double membrane in the proximal convoluted tubular cells and mesangial cells, with vacuolation and myelin figure formation in the mitochondria of the proximal convoluted tubular cells, at 72 hours and 168 hours in the 2 to 3 FU-PGA insert groups. The heart showed focal loss of cristae,vacuolation and myelin figure formation in the mitochondria of the 2 to 3 FU-PGA insert groups. In conclusion, despite the large amont of FU-PGA inserted, the histopathological changes in the liver, kidney and heart were slight, and consonant with the very low amount of 5-fluorouracil concentrations detected in the liver, kidney and heart. The above results suggest that the FU-PGA composite can serve as a new device for releasing drugs in a controlled manner and easily targeted to intraperitoneal organs. This device can improve the efficacy of intraperitoneal chemotherapy for gastric cancer.

Background: Various primary tumors can cause metastatic skin cancer. Metastatic skin lesion should be distinguished from other skin lesion. Objectives: We studied patients with metastatic skin cancer to find out average age, gender distribution, frequency of primary tumor, time interval between manifestation and primary cancer, and their clinical appearance, location and other metastatic sites. Methods: We reviewed the medical records, clinical photographs and histopathologic records of patients who had been diagnosed with metastatic skin cancer. Results: In the comparison according to clinical records, the mean age at the time of diagnosis was 60.6 years. The ratio of men to women was 1.05:1. The most frequent primary tumors were breast cancer (22.0%), lung cancer (17.0%), head and neck cancer (17%), melanoma (17.0%), gastrointestinal cancer (11%), urologic cancer (11%), and gynecologic cancer (6%). Metastatic skin cancers usually presented as discrete, painless, hard nodules, with sudden onset (88%). Conclusion: Based on the results of this study, it is believed that it is important to recognize the metastatic lesion between various skin lesion such as infections and granulomatous changes of other cause due to drugs and reactive changes.

Dong Bin Shin,Seung Bok Lee,Chang Sik Kim 대한안과학회 2003 Korean Journal of Ophthalmology Vol.17 No.2

We evaluated the change of corneal endothelium after trabeculectomy with mitomycin-C soaking (0.2 mg/ml, 2.4 ± 1.2 minutes) and the effect of viscoelastic material in reducing this change. In randomly selected cases, 0.05 ml of sodium hyaluronate (Healon??) was injected into anterior chamber (Healon group, n = 20), and same amount of balanced salt solution was injected in the other eyes (Control, n = 18) at the beginning of surgery. There were no differences in clinical variables and specular microscopy result between 2 groups before surgery. After surgery, the change of endothelial cells were significantly reduced in Healon group (cell density; -2.5 ± 1.6%, variability of cell area; 5.8 ± 2.5%, and percentage of hexagonal cell; -2.2 ± 0.7%) compared to control group (-7.7 ± 6.0%, 8.9 ± 4.4%, and -4.8 ± 3.5% respectively, p < 0.01). In trabeculectomy with mitomycin-C, the damage to the corneal endothelium was reduced significantly by injecting the viscoelastic material without significant complication.

( Young Bin Shin ),( Chang Il Kwon ),( Jeong Won Jo ),( Yun Sun Moon ),( Eui Chang Jung ),( Chi Yeon Kim ),( Tae Jin Yoon ) 대한피부과학회 2019 대한피부과학회 학술발표대회집 Vol.71 No.2

Background: As the incidence of skin cancer increases, more information and education on skin cancer are needed. Although skin cancer is not rare, most patients are little known about general awareness of skin cancer. Objectives: The purpose of this study is to investigate the post-education effects on skin cancer in our hospital outpaitents and carers. Methods: We reviewed a written questionnaire and patients’ self-checked records including patients’ basic medical information and knowledge of skin cancer protective modalities. Results: In total 340 cases, 215 (63.2%) patients were female and 125 (36.8%) patients were male. 6 people in their teens, 56 people in their 20s and 30s, 156 people in their 40s and 50s, 122 people in their 60s or older. Before education, 142 people said sunlight can cause a skin cancer and 178 did not. After education, 246 people said Yes and 94 people did not. When asked how you wanted to get more information on skin cancer, 104 (30.6%) people said that they were printed handout, 142 (41.8%) were visit to dermatologists, 52 (15.3%) were photos of skin symptoms, and 42 (12.3%) were phone calls. Conclusion: This result showed that people are little known about risk factor of skin cancer such as sunlight and artificial tanning. However, we found that through education, people's perceptions could change. The education on behavior for skin cancer prevention should be continued so that the awareness of the risk of skin cancer can be changed.

운동부하강도와 休息方法이 血液의 젖산濃度와 혈액성분변화에 미치는 效果

金昌根,朴喆斌 韓國體育大學校附屬 體育科學硏究所 1984 韓國體育大學校附屬 體育科學硏究所論文集 Vol.3 No.1

The purpose of the study was to investigate effects of work intensity and recovery patterns on changes of lactic acid concentration and blood components in endurance performances. 2 different work intensities and 5 different relief levels were used as protochol. Used 12 male endurance performers who belong to Korean National College of Physical Education as Subjects, and the results were summerized as follows; The increasing ratio of lactic acid concentration in blood was shown difference in accordance with work intensities, But with the same work intensity the increasing ratio of lactic acid concentration in blood was not only shown significant differences (p<0.01) in accordance with recovery patterns, but differences with work intensity were effected by individual variance. To improve capacity of tolerence against lactic acid accumulation, jogging with 60% of individual maximal speed was superior to jogging with 90% of individual maximal speed and 2, or 4 minutes of passive recovery between work sets. Both of lactic acid production and removal were significantly increased in jogging with 60% of individual maximalspeed, therefore, to improve anaerobic endurance, 2 minutes of passive recovery was recommended because of more rapid break down of lactic acid accumulation with 2 minute, or more passive recovery. The change of blood volume according to work intensity and recovery patterns, were not resulted from changes of blood cell but resulted from changes of albumin, total protein, and plasma potassium (p<0.01).

본 연구는 정기적으로 환경 전반에 대한 국민의 의식과 태도를 파악하기 위하여 기획되었으며, 매해 반복되는 기본부문과 당해 연도 정책이슈를 다루는 특별부문으로 구성된 2016년 국민 환경의식조사를 수행하고 환경에 대한 국민들의 인식을 살펴보았다. 2012년부터 시작된 국민환경의식조사의 기본 부문은 환경인식, 환경의식 및 태도, 환경 실천, 환경정책 수요, 삶의 질·지속가능성 부문으로 구성된다. 2016년 조사에서는 기후변화와 미세먼지가 특별 부문의 주제로 선정되었다. 본 설문조사는 전국의 만 19세 이상 69세 이하 성인 남녀 1,000명을 대상으로 조사전문기관의 방문면접조사를 통해 수행되었다. 환경 하면 떠오르는 이미지로 ‘기후 변화’라는 응답이 가장 높게 나왔고, 환경에 대한 만족도는 ‘자연 경관’에 대해 높게 나타났다. 국민의 과반수가 평소 환경문제에 대해 관심을 가지고 있는 것으로 나타났고, 환경보전이 개인에게 중요한 정도는 2015년에 비해 약간 감소하였으나 여전히 높은 수준을 보이며 국민의 대다수가 환경을 중요하게 생각하는 것으로 파악되었다. 생태주의적 세계관을 나타내는 점수는 2012년 조사 시작 이래 2015년까지 증가해오다 올해 조사 결과에서는 다소 감소하였다. 가장 우려하는 환경문제로는 ‘쓰레기 증가’를 꼽았고, 정보가 부족하다고 생각되는 환경문제로는 ‘자연자원의 고갈’을 응답하였다. 한편 환경오염 및 훼손에 대한 책임은 일반국민에게 있다고 생각하지만, 환경보전에 대한 책임은 주로 중앙정부에 있다고 생각하는 것으로 나타났다. 특별부문인 기후변화에서는 대부분의 응답자가 기후변화에 대해 인지하고 있는 것으로 나타났으며, 기후변화 하면 가장 먼저 떠오르는 이미지로 ‘평균 기온 상승’을 응답하였다. 대다수의 국민이 미세먼지에 관심을 가지고 있으나 우리나라의 미세먼지 수준에 대해서는 불만족스러워하는 것으로 나타났다. 또한 정부의 미세먼지 감축 노력에 대해서는 과반수의 국민이 부족하다고 느끼고 있는 것으로 파악되었다. 이와 같은 연속적인 국민환경의식조사 결과에 대한 정보를 통해 국민들의 인식 및 태도를 파악하고, 나아가 조사결과가 다양한 분석의 기초자료로 활용되어 정책의 활용도를 높이는 데에 일조하기를 기대한다. This study was planned to identify public awareness of and attitudes towards the environment on a regular basis. It conducted the 2016 survey of public attitudes towards the environment, which is consisting of the yearly repetitive basic parts and the special parts discussing issues of the year, and reviewed public awareness of the environment. The basic parts of the survey of public attitudes towards the environment that started from 2012 are composed of environmental perception, awareness of and attitudes towards the environment, environmental practice, demands for the environmental policies, and quality of life and sustainability. In the survey in 2016, climate change and particulate matter were selected as the subjects of the special parts. The survey was carried out on 1,000 men and women aged 19-69 years across the country through a face-to-face interview by a specialized survey agency. The image most associated with the environment was ‘climate change’, and the satisfaction for the environment was high with ‘natural landscape.’ It was identified that the majority of people were interested into the environmental issues in their everyday life. While the importance of environmental conservation to individuals slightly dropped from 2015, it was still high and most people was considering that the environment matters. The score of ecological world view had increased to 2015 from 2012 but slightly decreased this year. People chose ‘a rise in garbage’ as their most concerned environmental issue and ‘lacking natural resources’ as an environmental issue that they did not have enough information. On the other hand, people thought that the public was responsible for environmental pollution and damages but the central government should be held accountable for environmental conservation. In the special parts about climate change, most of the respondents were aware of climate change and answered that the image most associated with climate change was ‘average temperature rise’ It was figured out that most of the people were interested in particulate matter but dissatisfied with the level of particulate matter in South Korea. In addition, the majority of people thought that the government’s efforts to reducing particulate matter were not enough. It is expected to identify public awareness of and attitudes towards the environment based on the results of the annual survey of public attitudes towards the environment, and that the results can contribute to making policies as a fundamental data for various analyses.

Sensitivity analysis of satellite-retrieved SST using IR data from COMS/MI

( Eun Bin Park ),( Kyung Soo Han ),( Jae Hyun Ryu ),( Chang Suk Lee ) 대한원격탐사학회 2013 大韓遠隔探査學會誌 Vol.29 No.6

Sea Surface Temperature (SST) is the temperature close to the ocean`s surface and affects the Earth`s atmosphere as an important parameter for the climate circulation and change. The SST from satellite still has biases from the error in specifying retrieval coefficients from either forward modeling or instrumental biases. So in this paper, we performed sensitivity analysis using input parameter of the SST to notice that the SST is most affected among the input parameter. We used Infrared (IR) data from the Communication, Ocean, and Meteorological Satellite (COMS)/Meteorological Imager (MI) from April 2011 to March 2012. We also used the Global Space-based Inter-Calibration System (GSICS) correction to quality of the IR data from COMS. SST was calculated by substituting the input parameters; IR data with or without the GSICS correction. The results of this sensitivity analysis, the SST was sensitive from -0.0403 to 0.2743 K when the IR data were changed by the GSICS corrections.

뮤지컬〈여신님이 보고 계셔〉의 서사 구조와 뮤지컬 넘버의 극적 기능

신사빈(Sa-Bin Shin),이우창(Woo-Chang Lee) 한국콘텐츠학회 2014 한국콘텐츠학회논문지 Vol.14 No.3

뮤지컬 <여신님이 보고 계셔>는 ‘담론으로서의 서사’, ‘화자가 꾸미는 서사’, ‘스토리로서의 서사’ 등의 서사구조를 골고루 지니고 있다. ‘담론으로서의 서사’는 무인도에서의 남한군과 북한군의 우정을 그리는 것으로, ‘화자가 꾸미는 서사’는 순호·석구·주화·창섭·동현의 사연이 동현·여신·석구가 대역으로 등장하는 극중극으로, ‘스토리로서의 서사’는 ‘여신님’의 등장으로 현실 세계와 환상 세계가 교차하는 것으로 나타난다. 이는 △공간의 성격화 △무대의 전략적 간소화 △중심 캐릭터의 다수화 △유사 내력담의 반복 △탄력적인 시점 변화 등에 기여한다. 또 뮤지컬 넘버는 △극적 캐릭터의 다양성 추구 △비극적인 심리표현의 극대화 △아이러니와 판타지에 의한 흥미 유발 △섬세한 감성과 순수한 희망에 대한 향수 자극 △보편적 여성상에 의한 치유와 구원의 시도 등의 극적 기능을 지님으로써 이 뮤지컬의 사실적 재현과 양식적 환상에 기여한다. Ah! My Goddess has impressive narrative structure includinga narrative as a discourse, a narrative as a story and a narrative by narrator: in a narrative as a discourse, North and South Korean soldiers make friendship; in a narrative by a narrator, main characters (including Sun-ho, Seok-gu, Ju-hwa, Chang-seop and Dong-hyeon) appear in the outer story and narrate the inner story of characters (including Dong-hyeon, Goddess and Seok-gu) within the frame of aplay within a play; and in a narrative as a story, reality and fantasy intersect by the appearance of the Goddess. This narrativ estructure contributes largely to 1) the character formation of space, 2) the strategic minimization of the stage, 3) the multiplicity of main characters, 4) the repetition of similar life story, and 5) the flexible change of a point of view. And the musical number serves as dramatic functions such as 1) pursuing the multiplicity of characters, 2) maximizing the effect of the expression of tragic feelings, 3) drawing audiences interest by irony and fantasy, 4) evoking the nostalgia for delicate feelings and pure wishes, and 5) ordinary female characters playing the role of healing and salvation, there by contributing to the reconstruction of reality and the style of fantasy.
