The aim of this study was to compare a new type of reconstruction method (Noh's operation) with Roux-en-Y operation after subtotal gastrectomy. Noh's operation described herein includes a jejunal occlusion, an end-to-side gastrojejunostomy, a side-to-end jejunoduodenostomy, and a side-to-side jejunojejunostomy after subtotal gastrectomy. A series of 43 patients who had the new operation were compared with 47 patients with the Roux-en-Y procedure. The postgastrectomy syndromes, and the raucosal change of the remnant stomach and esophagus were evaluated after surgery. In the new operation, the Roux stasis syndrome occurred in 34.9% at 3 months, in 23.3% at 6 months, in 14.0% at 12 months, and in 11.6% at 24 months. In patients undergoing the Roux-en-Y operation, the syndrome occurred in 42.6% at 3 months, in 34.0% at 6 months, in 31.9% at 12 months, and in 29.8% at 24 months. This study shows that the new type of operation (Noh's operation) can be a good option for reconstruction after subtotal gastrectomy.

아버지의 학력, 자녀양육에 대한 부부 일치도 지각 및 다중지능과 유아의 다중지능과의 관계 연구

장영숙,노운서 한국영유아보육학회 2004 한국영유아보육학 Vol.0 No.39

본 연구는 아버지의 배경변인인 학력과 직업, 아버지의 심리적 변인인 아버지가 지각한 자녀양육에 대한 부부일치도, 그리고 아버지의 다중지능이 유아의 다중지능 발달에 어떠한 영향을 미치는지를 살펴보았다. 연구결과, 아버지의 학력에 따라 음악 지능과 신체 운동 지능 영역을 제외한 여섯 영역의 유아의 다중지능 발달에 차이가 있었으며, 아버지의 직업에 따라서 유아의 다중지능 발달은 차이를 보이지 않았다. 또한 음악지능, 논리수학지능, 언어지능, 대인관계 지능, 개인이해 지능, 자연탐구 지능에서 자녀 교육에 대해 부모간의 의견이 일치한다고 아버지가 지각할 때. 유아의 다중지능이 통계적으로 유의미하게 높게 나타났다. 유아의 다중지능의 여덟 영역과 아버지의 다중지능의 여덟 영역간의 상관관계를 살펴본 결과, 모든 영역에서 아버지의 다중지능과 유아의 다중지능 간에 매우 유의미한 상관이 있는 것으로 나타났다. This research analyzed how young children's multiple intelligences(MI) is related to their fathers' education, perception on couple's agreement for parenting style, and multiple intelligences(MI). Subjects were 259 preschool children and their fathers in Kwangju. Data were analyzed by ANOVA, Pearson's correlation, and multiple regression. The results of the study were as follows: First, young children's multiple intelligences showed significant differences according to father's education in the six areas of multiple intelligences, which is logical-mathematical intelligence, linguistic intelligence, spatial intelligence, interpersonal intelligence, intrapersonal intelligence, naturalist intelligence. Second, young children's multiple intelligences showed significant differences according to fathers' perception on couple's agreement for parenting style in the following five areas: musical intelligence, logical-mathematical intelligence, linguistic intelligence, interpersonal intelligence, intrapersonal intelligence. Third. correlation analysis between children's multiple intelligence and fathers' multiple intelligence showed that eight areas of intelligence were significantly correlated each other. In addition, young children's intelligence in each area of multiple intelligences was associated with their fathers' intelligence in that area.

정용석(Yong Seong Chung),이영철(Young Chul Lee),서강진(Kang Jin Seo),김명준(Myeong Jun Kim),정지혜(Ji Hea Jeong),노시태(Si Tae Noh) 한국고분자학회 2011 폴리머 Vol.35 No.6

바이오매스에서 유래된 2,5-dihydroxymethylfuran(DHMF)을 KMnO4 산화반응으로 furan-2,5- dicarboxylic acid(FDCA)를 합성하였다. 합성한 FDCA와 다이올류를 에스테르화 반응과 축중합 반응을 진행시 켜 폴리에스터를 중합하였다. 폴리에스터는 NMR을 통해 조성을 분석하였고 DSC와 TGA를 통해 열적특성을 분 석하였다. 합성된 폴리에스터의 고유점도는 0.78∼1.2 dL/g으로 상용화된 poly(ethylene terephthalate)(PET) 와 비슷하였다. 다이올의 길이가 증가할수록 Young`s modulus와 strength는 낮아지고 elongation-to-break는 높아지는 경향을 확인하였다. 합성한 poly(ethylene furandicarboxylate)(PEF)의 Young`s modulus는 3551 MPa, strength는 103 MPa로 상용화된 PET와 비슷하였다. Furan-2,5-dicarboxylic acid (FDCA) was synthesized by KMnO4 oxidation of 2,5-dihydroxymethylfuran( DHMF) derived from biomass. Polyesters were synthesized by esterification and polycondensation of FDCA with various diols(ethane-1,2-diol, propane-1,3-diol, butane-1,4-diol, hexane- 1,6-diol, decane-1,10-diol). The composition of polyesters was characterized by using 1H NMR. Thermal properties of the polyesters were characterized by DSC and TGA. Intrinsic viscosities(IV) of the polyesters were measured to be 0.78∼1.2 dL/g comparable with IV of commercial poly(ethylene terephthalate)(PET). As the chain lengths of diols increased, Young`s modulus and strength decreased and elongation-to-break generally increased. Young`s modulus and strength of the polyesters were measured to be 3551 MPa and 103 MPa, respectively, comparable with commercial PET.

Effect of Random Poisson's Ratio on the Response Variability of Composite Plates

Noh, Hyuk-Chun,Yoon, Young-Cheol Computational Structural Engineering Institute of 2010 한국전산구조공학회논문집 Vol.23 No.6

Together with the Young's modulus the Poisson's ratio is another independent material parameter that governs the behavior of a structural system. Therefore, it is meaningful to evaluate separately the influence of the parameter on the random response of the structural system. To this end, a formulation dealing with the spatial randomness in the Poisson's ratio in laminated composite plates is proposed. The main idea of the paper is to transform the fraction form of the constitutive coefficients into the expanded form in an ascending order of the stochastic field function. To validate the adequacy of the formulation, a square plate is chosen and the computation results are compared with those obtained using conventional Monte Carlo simulation. It is observed that the results show good agreement with those by the Monte Carlo simulation(MCS).

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.

류재호,노규태,이영석,이영호,권혁찬,김재석,김효진,이영민,박혜원,박근희 대한조혈모세포이식학회 2002 대한조혈모세포이식학회지 Vol.7 No.1

연구배경: 동일한 환자를 대상으로 조혈모세포이식 전 일반 병실에서의 관해유도 항암제치료 및 강화요법으로 인한 호중구감소 기간의 감염양상과 고용량 항암제치료 후 무균실에서의 조혈모세포이식 시 호중구감소 기간의 감염양상을 중심정맥관 관련 패혈증을 중심으로 비교 연구함으로써 효율적인 감염관리지침을 마련하고자 하였다. 대상 및 방법: 1999년 1월부터 2001년 7월까지 2년 7개월간 동아대학교병원 일반병실에서 악성혈액질환으로 항암제 치료를 받다가 조혈모세포이식을 시행받았던 22명을 대상으로 중심정맥관 관련 패혈증의 형태를 비교분석하였다. 결과: 대상 환자들의 일반병실과 무균실에서의 입원기간은 각각 32±13일, 33±19일, 호중구 감소기간은 15±12일, 17±18일, 호중구 감소기간의 발열 횟수는 14회, 14회로서 입원병실의 종류에 따른 차이는 없었다. 환자들의 중심정맥관 사용일수는 일반병실에서 29일(7~545일), 무균실에서 100.5일(25~606일)이었으며, 총 사용일수는 각각 1,515일, 3,250일로서 무균실에서의 중심정맥관 사용일수가 의미 있게 길었다(P=0.001). 중심정맥관 사용 일수에 대한 감염률은 각각 5.28/1,000일, 3.08/1,000일로서 일반병실에서 그 빈도가 높았으나 통계적 유의성은 보이지 않았다(P=0.141). 결론: 중심정맥관 삽입 후 일반병실에서 항암제 치료를 받던 환자가 조혈모세포이식을 위하여 무균실에 입원하는 경우, 중심정맥관을 교체하는 것이 감염관리를 위하여 바람직할 것으로 생각된다. Background: We compared the incidence of central venous catheter (CVC) related septicemia during neutropenic period in the same patient, which developed following chemotherapy for remission induction and consolidation, or hematopoietic stem cell transplantation (HSCT). Methods: We retrospectively reviewed the medical records and laboratory data of 22 patients with hematologic malignancies who received anticancer chemotherapy followed by HSCT at Dong-A University Hospital between January, 1999 and July, 2001. We investigated the duration of hospitalization, duration of neutropenic period, duration of catheterization, microbiologically documented organisms and incidence of CVC related septicemia. Results: The data in general ward (before HSCT) and laminar air flow room (after HSCT) were as follows: duration of hospitalization was 32±13 days and 33±19 days, duration of neutropenic period was 15±12 days and 17±18 days, median duration of catheterization was 29 days (7~545 days) and 100.5 days (25~606 days) (P=0.001), and incidence of CVC related septicemia was 5.28/1000 days and 3.08/1000 days, respectively. In the CVC related septicemia, the most common etiologic organism was coagulase negative staphylococcus. Conclusion: We suggest that the exchange of CVC before admission to laminar air flow room could decrease the incidence of CVC related septicemia in HSCT recipients.

송규상,강대영,최정목,노승무,정경수,오정연,김진향,양준목,최선웅,이진호,조준식,민병무,김용백,김창식,박근성,김승영,김학용,인현빈 충남대학교 의과대학 지역사회의학연구소 1998 충남의대잡지 Vol.25 No.1

To evaluate the in-vivo effects of mitomycin-C-polyglycolic acid composite(MMC-PGA) the disk: shaped composite were implanted into the peritoneal cavity of the Sprague-Dawley rats. The pathologic changes were examined at various time points up to 12 weeks. Initially the soft tissue around the inserted disks showed capillary congestion at 3 days. Inflammatory infiltrates with foreign body giant cells appeared from the 2nd week and reached peak response at 6-8 weeks. These reaction diminished prominently at 12 weeks. No specific pathologic change was found in the liver, the kidneys, and the heart. The above results suggest that the MMC-PGA composite can serve as a new device for intraperitoneal chemotherapy of various types of cancers.

연구배경:최근 당뇨병의 새로운 치료법으로 시도되고 있는 췌도이식은 충분한 췌도수의 확보와 췌도생존율을 높이기 위한 면역억제제 사용이 제한점이 되고 있다. 본 연구의 목적은 이식 전 충분한 췌도 수의 확보를 위해 분리한 췌도를 냉동보존하는 방법을 확립하고 냉동보존한 백서 췌도세포의 시험관내 그리고 생체내 기능을 조사하였다. 방법:분리한 백서의 췌장소도를 48시간 배양한 후 한 시험관당 췌도세포 1000개씩 나누었다. 냉동보존은 6개의 시험관에 DMSO를 첨가한 후 초 냉각(supercooling), 핵화(nucleation)단계를 거친 후 99% isopropanol과 액체질소가 들어있는 dewer를 이용하여-0.25℃/분의 냉각속도로 -40℃까지 단계적으로 얼린후-70℃ 액체질소 탱크에 보관했다. 해동은 냉동시킨 vial들을 액체 질소 태으에서 꺼내 37℃ 항온조에 담가 급격히 해동시킨 후, 원심분리하여 상층액을 제거하고 각 vial에 0.75M sucrose 용액을 가한 후, 10% fetal calf serum이 함유된 RPMI 1640 media에서 배양하였다 각각 6개의 시험관에서 해동한 췌도들을 광학현미경 및 형광현미경하에서 췌도의 모양과 생존율에 대해 조사하고 인슐린 정적반응을 알아보았다. 또한 분리한 췌도를 냉동보존하지 않고 이식한 경우를 대조군(6마리)과 생체내 기능을 비교하였다. 결과:① 냉동보존후 획득한 췌도의 수와 생존율 해동후 획득한 췌도의 수는 해동시킨 당일날이 902±21, 24시간 배양 후에는 857±16, 72시간 후에는 817±18개로 점차 감소되었다. AO/PI 염색상 각 췌도의 생존율은 냉동 전을 100으로 하였을 때 해동당일, 24시간 후, 72시간 후가 각각 60±5, 80±5, 90±5%로 해동후 3일간 배양하였을 때 냉동전의 수준으로 회복하였다. ② 냉동보존후 췌도의 포도당에 대한 정적 인슐린 분비능:냉동직후 감소된 경향을 보였으나 해동후 3일간 배양한 췌도의 인슐린 분비는 냉동전과 통계적으로 의미있는 차이가 없이 냉동보존 전의 수준으로 회복되었다. ③ 냉동보존후 췌도의 포도당에 대한 동적 인슐린 분비능:냉동보존한 췌도를 해동후 3일째의 인슐린 동적 분비능은 냉동 전과 마찬가지로 자극 인슐린의 반응의 제1기와 2기가 잘 관찰되었다. ④ 냉동보존한 췌도세포 이식 후 혈당 변화:스트렙토조토신으로 유도된 당뇨병 쥐에 췌도이식 후 혈당은 냉동보존한 췌도이식군에서 대조군에 비해 혈당의 조절효과가 더 오래 지속되었다. 결론:소동물에서 단계적 온도 하강법을 이용한 췌도세포 냉동보존법을 확립하였으며 이는 기능, 구조 및 생존율에 큰 이상을 보이지 않았으므로 장차 사람의 췌도세포 동종이식시 부족한 췌도세포수를 극복하고 면역반응을 줄일 수 있는 매우 유용한 방법이 될 것으로 판단된다. Background : Although islet transplantation has been attempted to reverse the state of diabetes, achieving a critical number of islets and modulating the immune response limit the success of islet transplantation. Cryo-preservation of islets offers many important benefits for islet transplantation by collecting islets with a wide variety of HLA phenotypes and islet MHC expression. The aims of this study was to determine the optimal conditions for cryo-preservation by using a controlled cooling method and to evaluate in vitro and in vivo functional properties of the cryo-preserved islets. Methods : Collagenase-isolated, Ficoll-purified islets were cultured for 48 hours. They were aliquoted into freezing tubes (1000 islets per tube), equilibrated with 2M dimethyl sulfoxide (DMSO) in three steps, supercooled, nucleated, and controll-cooled at rate of 0.25℃/min to - 40℃ prior to storage at - 196℃. Rapid thawing and removal of DMSO with 0.75 M sucrose preceded 48 hour of culture and the morphology, viability, glucose-induced insulin secretion, and in vivo function of rats transplanted with cryopreserved islets was reexamined. Results : ① Recovery was 90.2±0.2%, 85.7±0.1% and 81.7±0.1% immendiately after, 24 hours and 72 hours after thawing respectively. The viability was 60±5%, 80±5%, 90±5% immediately after, 24 hours and 72 hours after thawing respectively. ② The glucose-stimulated-insulin secretion (GSIS) tended to decrease immediately after thawing, but GSIS increase to the level of pre-cryopreservation 72 hours after thawing. ③ The in dynamic GSIS, the first and the second phase of insulin secretion were well preserved in islets cultured for 72 hours after thawing. ④ The cryopreserved islets were cultured for 3 days and transplanted into renal sub-capsular space of streptozotocin (STZ) induced diabetic rats. The duration of normoglycemia in the STZ-induced diabetic rats transplanted with cryopreserved islets was significantly longer than of the fresh islets. Conclusion : The optimal condition of cryopreservation using the controlled cooling method was established in rat pancreatic islets. This cryopreservation method can be a feasible approach for human islet transplantation (J Kor Diabetes Asso 26:64~74, 2002).

運動會 프로그램에 關한 調査 硏究(一)

盧永九 대구교육대학교 1976 論文集 Vol.12 No.-

In this paper I tried to study on the basic items of the 112 programs in the athletic meetings of many different primary schools being located in Kyung Sang Puk Do. Above all I investigated what kind of items the programs of the athletic meetings had chosen in each primary school according to some athletic types. And then I classified the items of the programs being already selected into several types according to each grade of primary school. But the most important point in my paper was to make clear the reasone why each primary school should choose such items in the program of its athletic meeting and something to make better. Of course, I dealt with all these problems by means of the statistical method.
