신동인과 오정환의 이력은 평범하다. 하지만 두 사람의 이야기는 정보가 쌍방향으로 공유되는 디지털인터넷사회에서 한국현대사를 새롭게 볼 수 있는 기회를 제공한다. 같은 공간 속에서 비슷한 시기를 살았던 신동인과 오정환은 자신들의 관점으로 광복, 한국전쟁, 농지개혁, 통일벼 보급 등의 굵직한 역사적 사건들을 이야기한다. 신동인과 오정환의 삶은 기존의 공식역사에서 주인공이었던 지배층·승자·영웅 등의 삶에 비하면 평범하고 무난하다. 하지만 다른 관점에서 보면 두 노인의 삶은 평범하지 않을 수 있다. 두 노인은 지역 내에서 나름대로 좋은 입안에서 태어나, 괜찮은 직업을 가졌던 사람들이다. 또 노년에 부를 축적하였으며, 자손들도 잘 되었다. 실제로 신동인과 오정환은 스스로 성공한 삶을 살았다고 평가한다. 현대사의 굴곡진 상황 속에서 고향을 떠났거나, 두 노인에 비해 사회적·경제적 성공을 이루지 못한 사람들의 눈에는 신동인과 오정환의 삶은 평범하게 보이지 않는다. 개인의 기억은 고정점과 지향점이 다르며, 훗날의 경험과 결합하여 변형된다. 이 때문에 신동인과 오정환의 기억을 담은 자선전은 전체의 역사를 대변할 수 없으며, 기존의 공식 역사를 대체할 수 없다. 다만 두 사람은 누구보다 스스로 행동하고, 이유 있는 삶을 살았다. 자신을 공식 역사에 복무하는 조연으로 생각하지 않고, 자기의 인생을 사는 주인공으로 여겼다. 그렇기에 우리는 두 노인의 이야기에 귀를 기울일 수 있으며, 공감할 수 있다. 역사탐구의 목적이 과거를 통해 현재를 성찰하고 미래에 대비하는 것이라면, 두 사람의 자서전은 하나의 사료가 될 수 있다고 생각한다. Shin Dong-in was born in Shingye-ri, Yiwol-myeon, Jincheon-gun, Chungcheongbuk-do in 1934. He has ever lived in Jinhae and Seoul in his younger days for a short time. He had lived most of his life in his home town. Oh Jeong-hwan was born in Samyong-ri, Yiwol-myeon, Jincheon-gun, Chungcheongbuk-do in 1927. He worked as a teacher until early forty and for a short time, ran printing shop in Cheongju. However, he went back home and did farming until he passed away. Their career was common. But their stories provide an opportunity to newly see Korean contemporary history in the digital internet society where information are shared in interactive way. Shin Dong-in and Oh Jeong-hwan who had lived in the same space in the similar time told about important historical events like the restoration of independence, Korean war, farmland reform, spread of unification rice etc. from their views. Their lives were common and easy compared to life of governing group, winner, hero etc. who were protagonist in the existing official history. However, from another view, the lives of the two old men were not common. The two persons were born in a good family in the region and had a good job. And they accumulated wealth in the old age. Their descents lived happy life. Actually, they themselves assessed that their lives were successful. Their lives would be not common from the views from people who left hometown in the midst of situation with ups and downs of contemporary history, or thought that they lived lives with failure. The memory of individual has different fixed point and directed point. And the memory is transformed, being connected to future experiences. Autobiography expressing their memories cannot represent whole history and cannot replace existing official history. But the two men acted by oneself than anyone else and lived life with reason. They did not think that they played a supporting role only for official history. But they regarded them as a hero to live their own life. Therefore, we can carefully listen to their stories and feel sympathy. If purpose of history investigation is to reflect present through the past and prepare for the future, the autobiographies of the two men can be historical materials to help orientation of life.

토양으로부터 분리한 Metarrhizium anisopliae (Metschn.) Sorok이 생산하는 biopolymer를 정제하여 분석하고, 그의 생산조건을 검토하였다. 탄소원으로 mannitol, 질소원으로는 polypepton을 사용했을 때 가장 많은 biopolymer를 생산하였고 K_2HPO_4 및 CaCl_2를 첨가함으로서 생산량이 더욱 증가하였다. 또한 이 biopolymer를 정제하여 그 분자량과 구성성분을 검토한 결과 Metarrhizium anisopliae(Metschn.) Sorok이 생산하는 Biopolymer YU-122는 분자량이 1.7×10 exp (6)이고, C, H의 구성비가 1:2이며 미량의 N이 검출되었으나, 주 구성성분은 glucose와 galactose의 환원당으로 이루어져있는 전혀 새로운 biopolymer인 것으로 나타났다. To produce biopolymer, Metarrhizium anisopliae (Metschn.) Sorok was cultured in a medium containing glucose 1.0%, sucrose 2.0%, soluble starch 1.0%, yeast extract 0.5%, polypeptone 0.5%, K_2HPO_4 0.1%, MgSO_4·7H_2O 0.02%. The culture broth was centrifuged and the polymer was harvested by adding methanol to the culture supernatant. When three times of methanol was added, the polymer was coagulated and precipitated. Then it was further purifued through successive SK-1B, SA-20P, HP-20 column chromatographies. This polymer was designated as Biopolymer YU-122. C:H ratio of this Biopolymer YU-122 was 1:2 and small amount of N is detected by CHN analyzer. Glucose and galactose are main components of this polymer. Average molecular weight of this biopolymer was 1.7×10 exp (6) by Sepharose 4B gel permeation chromatography. Optimal condition for biopolymer production was investigated. When 5% of mannitol was used as a carbon source, and polypepton as a N source, highest productivity of biopolymer was achieved. C/N ratio as nutrient was also a major factor in polymer production and its optimal ratio was 3.

심한 저칼륨혈증을 동반한 갑상선 중독성 주기성 마비 2례

Thyrotoxic periodic paralysis occurs primarily in Orientals with an overwhelming male preponderance and a higher association of specific HLA antigens. Clinical manifestations include onset after high carbohydrate ingestion or heavy exertion with progressive symmetric weakness leading to flaccid paralysis of the extremities and other muscle groups, lasting several hours. Other precipitating facters include trauma, infection, administration of epinephrine, thyroid hormone, or corticosteroid. If hypokalemia is present, potassium administration may help abort the attack. Although propranolol can be efficacious in preventing further episodes, the only definitive treatment is euthyroid state. The pathophysiology is still controversal, but reflects altered potassium and calcium dynamics as well as certain morphologic characteristics within the muscle unit itself. We discribed two patients with thyrotoxic periodic paralysis who had a no familial history of paralysis and had a decreased level of serum potassium during attack.

We investigated the variation of PR signals for n-GaAs surface treated with Fe as annealing method. The samples were annealed by isochronal(200∼600 ℃, 10 min) and isothermal(300 ℃, 10 ∼60 min) method. In PR signals measured from isochronal annealed samples, the rate of intensity decreasing for n-GaAs was 49%, and that for n-GaAs surface treated with Fe was 66%. We assumed that the large amount of decreasing intensity for Fe contaminated sample caused by decreasing carrier density due to increasing of ?? neutral acceptor at higher annealing temperature. In PR signals measured from isothermal annealed samples, the signals for annealed n-GaAs decreased with increasing annealing time, and the signals for n-GaAs surface treated with Fe continuously increased with increasing annealing time. It can be assumed that the increasing of PR intensity for Fe contaminated samples as annealing time caused by the diffusion of Fe atoms from the surface.

당뇨병성 합병증을 가진 환자에서 혈중 Erythropoietin 농도

김동규,유기동,허광식,김상용,윤성호,조영신,권용은,김태원,김건영,정종훈,배학연 朝鮮大學校 附設 醫學硏究所 1998 The Medical Journal of Chosun University Vol.23 No.1

연구 배경 : 고혈당성에 의한 산화환원반응 이상(가저산소증)이 조절 되지않는 당뇨병의 특징으로 혈관과 신경 기능에 대한 진성 저산소증의 효과와 유사하며, 당뇨 합병증의 병태생리에 중요한 역할을 한다. 고혈당이 있는 인슐린 비의존형 당뇨병 환자에서 인슐린 수준이 정상이듯이, 빈혈이 있는 당뇨병 환자에서 EPO의 농도는 실제 혈색소 농도의 감소비율과 차이가 있을 것이라 추측된다. Friedman 등은 당뇨병성 합병증 원인 인자로 가저산소증(pseudohypoxia) 또는 저산소증(hypoxia)을 제기하였고 이런 인자들이 EPO의 상대적 또는 절대적 결핍에 의한 것임을 보고하였다. 방법 : EPO-Trac^(TM 125)I RIA kit을 이용하여 방사면역측정법으로 EPO 수준을 검사하였다. 전혈 3㎖을 5-10㎖ 시험관에 정맥 채혈하였으며, 용혈과 장기간의 보존을 위하여 원심분리를 즉시 시행하여 혈청을 영하 200C에서 냉동 보관 후 일괄적으로 검사 결과를 얻었다. 결과 : 1996년 9월부터 1997년 2월까지 조선대학교 부속병원 내과에 입원한 2형 당뇨병 환자 63례를 대상으로 하여 다음과 같은 결과를 얻었다. 1) 당뇨병성 합병증이 없는 군과 있는 군간의 혈색소, 혈중 EPO농도의 차이는 유의한 차이가 있었으며 혈색소의 감소율보다 혈중 EPO의 감소율이 더 높았다. 2) 당뇨병성 망막증의 유무에 따른 혈색소 농도의 차이는 유의한 차이가 없었으나 혈중 EPO농도는 유의한 차이가 있었다. 증식성군에서만 혈중 EPO의 감소비율이 혈색소에 비해 높았다. 3) 당뇨병성 신증의 유무에 따른 혈색소, 혈중 EPO농도는 유의한 차이가 있었고 혈색소 감소율에 비해 EPO농도의 감소율이 높았다. 신증의 중증도에 따른 혈색소, EPO의 차이는 미세알부민뇨군을 제외하고는 유의한 차이를 보였고 혈색소 감소율에 비해 EPO의 감소율이 더높았다. 4) 당뇨병성 신경병증의 유무에 따른 혈색소 농도의 차이는 유의한 차이가 없었으며 EPO농도는 유의한 차이를 보였다. 혈색소와 EPO의 감소비율은 비슷하였다. 신경병증의 중등도에 따른 혈색소와 EPO농도의 변화는 유의한 차이가 없었으나 stage 3에서는 혈색소감소율보다 EPO감소율이 더높았다. 결론 : 당뇨병성 합병증을 가진 환자에서 빈혈의 정도는 대부분 혈청 EPO치의 절대적 감소에 의함을 간접적으로 밝혀낼 수 있었으며 차후 더 많은 대상으로 비교 분석이 필요하리라 사료된다. Background: Hyperglycemic-induced redox(pseudohypoxia) imbalance is a characteristic feature of poorly controlled diabetes that mimics the effects of true hypoxia on vascular and neural functions and plays an important role on the pathogenesis of diabetic complications. As is true for apparently "normal" insulin levels typically found in NIDDM even in the presence of hyperglycemia, a "normal" erythropoietin level in an anemic diabetic subject may be disproportionally low for the actual red cell mass. Therefore, Friedman et al suggested that pseudohypoxia or hypoxia as an etiological factor of diabetic complications are due to absolute or relative erythropoietin deficiency Method: EPO-TracTM 125I RIA kit was used for the quantitative determination of erythropoietin(EPO) in serum by radioimmunoassay. An adequate sample of blood (3ml whole blood) was collected aseptically by venipuncture in a 5~10ml glass tube to yield a minimum of 400 L of serum per assay. The serum was promptly removed from the clot by centrifugation in order to avoid hemolysis. Then to increase its storage time it was frozen at -200C in a nonself defrosting freezer. Finally, tests were undertaken simultaneously Results We studied 63 cases with diabetes mellitus, who were admitted to Chosun University Hospital from September, 1996 to February, 1997 at the Department of Internal Medicine. We defined the control group, as diabetic patients who did not have anemia(<13mg/dl), diabetic complications(retinopathy, nephropathy, neuropathy) and the remainders were defined as the experimental group(we excluded anemic patients, who had secondary causes of anemia and diabetic patients with end stage renal disease)Data were as follow 1) The relationship of Hb and the 24hr urine protein between diabetic patients with and without complications significantly differed(p=0.02, < 0.001 respectively), but the Hb level was poorly related between diabetic patients with and without retinopathy(except in preproliferative, proliferative subgroups) and neuropathy. 2) Subgroups of patients with diabetic complications had higher 24hr urine protein than patients without diabetic complications, except stage I diabetic neuropathy 3) The EPO level was significantly different between diabetic patients with and without complications. 4) The correlation between EPO and Hb was significantly different, especially in diabetic patients with retinopathy and nephropathy according to severity of diabetic complications, compared with patients who did not have diabetic complications such as retinopathy and nephropathy. Conclusion: We know that anemia induced by diabetic complications is due to relative EPO deficiency than absolute EPO deficiency, and further evaluation and studies are needed on many cases in the future

동종 조혈모세포이식 후 발생한 크립토콕쿠스 척추염 1예

고윤호,임동준,이성수,조유경,이동건,최정현,김유진,민창기,김동욱,박정미,김춘추,신완식 대한감염학회 2001 감염 Vol.33 No.4

Skeletal cryptococcosis is an uncommon infection. Cryptococcus is a common cause of meningitis and infects 7∼10% of patients with AIDS. As well as AIDS, the infection may be seen in association with leukemia, lymphoma, Hodgkin's disease, sarcoidosis, tuberculosis and diabetes, also in patients on steroid medication. But there is no case report of skeletal cryptococcosis following allogeneic hematopoietic stem cell transplantation. A 40-year-old woman was admitted to the hospital because of low back pain. She had chronic myelogenous leukemia for 2 years and underwent allogeneic hematopoietic stem cell transplantation 8 months ago. She have been treated with steroid and cyclosporine orally because of chronic graft versus host disease. On examination she was afebrile and had posterior lower lumbar tenderness. But, she had no reduced strength of low extremities. Open biopsy was underwent. Histology demonstrated budding, round-to-oval, refractile yeast-like organisms within debris. The results of a lumbar puncture were unremarkable and cerebrospinal fluid culture failed to grow bacteria and yeast. The patient was treated with amphotericin B (1 gram) and AmBisome□ (2.8 gram) over 6 weeks. Three months after cessation of therapy, the patient was doing well.(Korean J Infect Dis 33:298∼301, 2001)

김동렬,유재인,배인호,박성배,신영남 大邱大學校附設 基礎科學硏究所 1998 基礎科學硏究 Vol.15 No.2

Photoluminescence(PL) has been applied to characterize the transition in contaminated n-GaAs with Iron. The PL spectrum of the bulk n-GaAs at 15 K showed two peaks, one is the DAP peak located at 1.477 eV and the other is the Ga vacancy peak around 1.4973 eV. The PL spectrum of the Fe contaminated n-GaAs showed peak located at 1.4795 eV with broade the full with half maximum that relate with Fe acceptors. From temperature dependent PL intensity, activation energy E_(u) is determined to be 35 meV.

정동일,공현희,김태호,황미열,유학선,윤호철,설성용 경북대학교 의학연구소 1999 경북대학교병원의학연구소논문집 Vol.3 No.1

콘택트렌즈 보존 용기 유래 가시아메바 KA/L5주의 세포질 내에 존재하는 bacterial endosymbiont(내공생세균)를 투과전자현미경으로 관찰하여 확인하였다. 숙주인 가시아메바 KA/L5주는 형태학적으로 제2군에 속하였고, rDNA PCR-RFLP 결과 A. lugdunensis로 동정되었다. 미토콘드리아 DNA RFLP와 동위효소 분석상 이 충주는 국내 콘택트렌즈 보존용기에서 가장흔히 분리되는 type인 KA/Ll주, 국내 임상 분리주 중 하나인 KA/E2주, 내공생세균을 가지는 것으로 보고된 병원 냉각수 유래 KA/W4주 및 L3a주와 동일하거나 매우 유사한 성적을 보였다. 내공생세균은 약 1.38× 0.507㎛의 크기였고, 아메바 세포질 내에 불규칙하게 분포하고 있었으며. 그 표면에 아메바의 ribosome이 부착되어 있었다. 내공생세균을 둘러싼 lacunae나 막과 같은 구조는 관찰되지 않았다. Legionella 특이 primer를 이용한 효소중합반응(PCR)에서 내공생세균의 염색체 DNA는 증폭되지 않았다. A. lugdunensis의 우리말 이름을 담수가시아메바로 제안한다. Transmission electron microscopy of an Acanthamieba isolate (KA/L5) from a contact lens case revealed bacterial endosymbionts within cytoplasm of the amoebae, The Acanthamoeba isolate belonged to the morphological group II. Based on the polymerase chain reaction (PCR) - restriction fragment length Polymorphism (RFLP) of 18S ribosomal RNA coding DNA (rDNA), the Isolate was identified as A. lugdunensis. Strain typing by isoenzyme analysis using isoelectric focusing (IEF) and mitochondrial (Mt) DNA RFLP revealed that the isolate was closely related with KA/Ll , the most predominant type of isolates from contact lens storage cases, KA/E2, a clinical isolate, KA/W4, preciously reported to host endosymbionts, and L3a strains of A. lugdunensis. The endosymbionts were similar to those of KA/W4 In aspects that they were randomly distributed in both trophozoites and cysts, and were rod-shaped bacteria measuring approximately 1.38x 0.50㎛. But the number of endosymbionts per amoeba was significantly lower than that of KA/W4. They were neither limited by phagosomal membranes nor included In lacunae- like structure.
