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.

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.

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)

유동식,하진욱 한국공업화학회 2005 응용화학 Vol.9 No.1

The photodegradation of IPA according to coating conditions was examined by TiO₂/P-25-coated. POF. The following results can be concluded. In the photoactivity of TiO₂-coated POF, ethanol solvent was higher than other solvents. Inorganic(KR-400), organic(A-9540) and inorganic-organic hybrid(GPTMS·TMOS) resins were used as binder. TiO₂ coated surface of POF was clear with all binders. Organic binder(A-9540) showed the highest activity for IPA degradation. But organic binder was degraded by TiO₂, inorganic binder had lower binder ability than others. The optimum activity obtained when the ratio of TMOS and P-25 was 0.05~1:1.

자일리톨과 불화나트륨을 함유한 저작성 정제가 교정환자의 구강위생에 미치는 영향에 관한 임상시험

유상훈,안석준,이신재,백승학,김태우,장영일,남동석 대한치과교정학회 2003 대한치과교정학회지 Vol.33 No.2

본 연구는 불화나트륨과 자일리톨 성분으로 구성된 구강 청정용 저작성 정제(덴포정, 하미즐, 부천, 경기)가 교정치료 중인 환자의 구강위생 상태에 미치는 영향을 알아보기 위해 시행되었다. 교정치료 중인 18세 이상의 성인 환자 30명을 대상으로 약제 상요 전, 2주 후, 4주 후에 피험자의 상악과 하악 전치 부위 및 구치 부위에서 각각 치은 지수, 치은 출혈 지수, 치태 지수를 측정하여 다음과 같은 결과를 얻었다. 1. 상하악 전치부와 구치부 모두에서 치태 지수가 약제 사용 전에 비해 사용 2주 후와 4주 후 유의성 있게 감소하였다(p<0.05). 또한, 적용 2주 후와 4주 후의 지수를 비교하였을 때 4주 후에 좀 더 개선된 경향을 보였으나, 통계적 유의성은 나타나지 않았다(p<0.05). 2. 치은 지수, 치은 출혈 지수도 상하악 전치부와 구치부 모두에서 적용 전에 비하여 2주 후와 4주 후 유의성 있게 감소하였다(p<0.05). 적용 2주 후와 4주 후의 지수의 비교 검증에서 통계학적으로 유의할 만한 차이가 보이지 않아 구강위생 상태의 개선이 계속 유지됨을 보였다. 본 연구의 결과는 치태 지수, 치은 지수, 치은 출혈 지수가 실험 정제 적용 후에 감소하여 구강위생 상태가 개선되었음을 보였다. 이러한 결과를 통해 덴포정을 교정치료 중인 환자에서 부가적으로 사용하였을 경우 치주조직의 건강을 증진시키는데 도움을 줄 수 있으리라고 생각된다. The aim of this study was to evaluate the effect a chewable tablet containing sodium fluoride and xylitol (DenPo, Hamizzle, Bucheon, Kyungki) on the oral hygiene state in the orthodontic patients. The subjects consisted of 30 adult orthodontic patients, who have worn the fixed orthodontic appliance at least 6 months. They were instructed to use the tablet forth a day. Gingival index (GI), plaque index (PI), and sulcus bleeding index (SBI) of upper and lower anterior and posterior regions were measured before using the tablet (TO), 2 weeks after using the tablet (T1), and 4 weeks after using the tablet (T2). The data were analyzed with Wilcoxon signed ranks tests. The results were as follows ; 1. PI was decreased significantly in the T1 and T2 stage compared with TO stage in the both anterior and posterior regions (p<0.05). Although PI was decreased in the T2 stage compared with T1, there was not statistical significance(p>0.05). 2. GI and SBI showed similar results compared with PL. In the T1 and T2 stage, there was statistically significant decrease in the GI and SBI (p<0.05). This study showed that the DenPo tablet could be used as an adjunct to improve oral hygiene in the orthodontic patients. The decrease of the indices may suggest that DenPo tablet could be effective in the plaque removal and prevention of gingival inflammation in the orthodontic patients.

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.
