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.

최용석,옥승호,유주현,배동현 한국산업미생물학회 1997 한국미생물·생명공학회지 Vol.25 No.1

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.

Dong­Geun Kang,Young­Jin Park,Jae­Ha Yu,Jong­Byung Oh,Dong-Yeong Lee 대한슬관절학회 2019 대한슬관절학회지 Vol.31 No.1

Purpose: The purposes of the present study were to review published studies that investigated arthroscopic meniscus repair to treat meniscus injury in young patients and to compare all­inside and inside­out suture techniques.Methods: Various electronic databases were queried for published articles, and this search was updated in August 2017 for evaluating the outcomes of arthroscopic meniscus surgery in young patients. Data search, extraction, analysis, and quality assessment were performed according to the Cochrane Collaboration guidelines, and the clinical outcomes were evaluated using various outcome values in young patients according to suture techniques.Results: Three randomized controlled trials and three prospective comparative studies were included in this systematic review and meta­analysis. There were no significant differences in clinical outcomes such as meniscus healing rate (risk ratio [RR], 1.11; 95% confidence interval [CI], 0.90 to 1.37; I2=39%) and perioperative complications (RR, 0.62; 95% CI, 0.23 to 1.72; I2=43%) between all­inside and inside­out techniques for meniscus repair.Conclusions: The present study shows favorable results for clinical outcomes such as meniscus healing rate and perioperative complications in young patients. Furthermore, based on our results, both all­inside and inside­out meniscal suture techniques are equally effective in these patients.

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)

효소처리 찹쌀 전분의 이화학적 성질 및 유과제조 특성

유철,김종태,허남윤,김동섭,백무열 경희대학교식량자원개발연구소 2007 硏究論文集 Vol.26 No.1

유과 제조 시 제조 시간을 단축할 수 있는 소재를 개발하기 위하여 찹쌀 전분을 4가지 상업용 α-amylase 효소와 반응시켜 효소처리 찹쌀 전분을 제조하고 이들의 이화학적 특성을 연구하였다. 효소처리 찹쌀 전분의 팽윤력 및 용해도는 일반 찹쌀 전분에 비해 많이 증가되는 경향을 보였다. 등온흡습곡선에서는 효소처리에 따른 유의적인 차이는 나타나지 않았다. RVA특성을 검토한 결과 최대 점도, holding strength, final viscosity, break down, setback은 일반 찹쌀 전분보다 낮아지는 결과를 나타냈다. 열적특성에서는 아밀로펙틴 용해 개시온도, 아밀로펙틴 용해 종결온도 그리고 아밀로펙틴 용해 온도범위(△T)는 각 전분간에 유의적인 차이가 나타나지 않았으며 아밀로펙틴 용해 엔탈피 역시 유의적인 차이를 나타내지 않았다. X-ray 회절 분석 결과로 볼 때, 효소처리 찹쌀 전분 및 일반 찹쌀 전분 모두 A형의 결정 형태를 나타내었고, 상대적 결정화도의 차이가 나타나지 않는 것으로 보아 효소처리가 찹쌀 전분의 결정형영역에는 영향을 주지 않는 것으로 보여진다. 효소처리 찹쌀 전분을 사용하여 제조한 유과의 경우 과도한 점도손실에 의해 반죽을 제조하지 못하여 본 연구에서 사용한 효소치리 정도가 부적합한 것으로 판단되었다. Physicochemical properties of partially hydrolyzed waxy rice starches with various α-amylases were investigated to reduce processing-time of yukwa (Korean traditional puffed rice snack). Four commercial α-amylases (Fungamyl, Termamyl, Liquozyme, Kleis tase) were used in this work. Waxy rice starches (20% solid content) were treated with same unit of four α-amylases at 40℃ and pH 6.0 for 1 hour. Partially hydrolyzed waxy rice starches showed higher swelling power and solubility than native waxy rice starch. Pasting temperature and peak viscosity of partially hydrolyzed waxy rice starches were lower than those of native starch. DSC thermal transitions of partially hydrolyzed waxy rice starches shifted to higher temperature than native waxy rice starch possibly due to hydrolysis of amorphous region and some double helical structure. X-ray diffraction patterns of both native and partially hydrolyzed waxy rice starches were typical A-type pattern indicating that alpha-amylase cannot disrupt the crystalline structure in this condition.

장애인 취업알선 서비스가 고용의 질에 미치는 영향

유동철 한국장애인고용촉진공단 고용개발원 2008 장애와 고용 Vol.18 No.1

The purpose of this study is to analyze empirically the effects of job placement services on quality of work of the people with disabilities. In order to pursue such goal this study used ‘the disabled workers survey data’conducted by KEPAD(Korea Employment Promotion Agency for the Disabled) in 2005. The data were analysed by logit, multiple regression analysis. The major findings are: (1) The disabled who were helped by job placement service center had higher probability in employment at large enterprises than not helped. (2) Job placement services increased the probability of irregular employment. (3) Job placement services decreased the wage per hour. According to the findings of this study, I recommended to introduce One-Stop Career Service Delivery System based on Employment Support Center, and case management system, to encrease co-work of KEPAD and Employment Support Center, and to re-classify the work rehabilitation center by transitional employment level. 본 연구는 장애인에 대한 공공서비스 중 취업알선서비스가 장애인의 고용의 질에 미치는 영향을 실증적으로 분석하기 위한 것이다. 자료는 2005년 한국장애인고용촉진공단에서 조사한‘장애인근로자 실태조사’원자료를 이용하였다. 분석 결과 취업알선 서비스를 받은 장애인의 경우 스스로 알아서 취업한 장애인에 비해 300인 이상 사업체에 취업할 확률은 높아지나 임시·일용직에 취업할 확률 또한 높아지는 것으로 나타났으며, 임금은 오히려 취업알선 서비스를 받지 않은 장애인근로자에 비해 더 낮은 것으로 나타났다. 이러한 문제를 극복하기 위해 고용지원센터를 중심으로 한 원-스탑 서비스 전달체계의 구축, 사례관리팀의 구성, 직업재활실시기관의 기능별 재분류를 통한 고용 기능의 강화 등의 정책적 대안을 제시하였다.

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.
