      • Poster Session : PS 0831 ; Upper GI Tract : Clinical Factors to Predict Angiographically Detectable Non-Variceal Upper Gastrointestinal Bleeding in Patients Refractory to Endoscopic Treatment

        ( Tae Hwan Ha ),( Tae Hoon Oh ),( Sung In Yu ),( Min Kim ),( Jong Wook Kim ),( Won Ki Bae ),( Jae Hyung Kim ),( Seung Suk Baek ),( Mi Jin Ryu ),( Ye Na Choi ),( Ji Young Park ),( Eileen L Yoon ),( Tae 대한내과학회 2014 대한내과학회 추계학술발표논문집 Vol.2014 No.1

        Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

        김중업의 「경주 석굴암 보수공사 설계」(1961-1962)에 관한 고찰

        우동선,김태형,Woo, Don-Son,Kim, Tae-hyung 한국건축역사학회 2021 건축역사연구 Vol.30 No.4

        This study examines the Gyeongju Seokguram Grotto restoration project (1961-1962) by architect Kim Chung Up (1922-1988) and introduces the documents he wrote at the time of planning. The study highlights Kim's Plan attempt to adopt Buckminster Fuller's idea of the Geodesic Dome, while inheriting the architect Pai Ki Hyung's previous design plan which was nullified. As Seokguram Grotto's water leak and deterioration issues have been brought up, the four-times survey was carried out by experts team between 1958 and 1960, under Ministry of Education's direction. Pai designed an initial restoration plan based on the survey's result, which was a double-dome structure with a concrete film on the outer periphery as a way to protect Seokguram Grotto in January 1961. However, as drawbacks, such as the heavy load of the concrete dome, and non-installation of entrance hall, have been indicated in the review process, the Cultural Properties Committee rejected the plan. Subsequently, Kim was appointed as the supervisor of the second restoration project. Kim drew up a process management schedule to be implemented from August 1961 to December 1963 and designed the conception plans for the second restoration design. This study analyzes Kim's Plan by examining sketches, site plans, floor plans, and sections. Kim planned to maintain the idea of the double-dome structure proposed by Pai while applying Buckminster Fuller's idea of the Geodesic Dome. Kim planned to lighten the dome structure by applying a steel-frame Geodesic Dome so that the dome structure could be supported by its own. The study is expected to reclaim the omitted parts from Seokguram Grotto's historical description and Kim's careers.

        The current study evaluates the capacity of eugenol to regulate immediate allergic reaction by control of histamine release. Administrations of eugenol (1 M/kg. i.p.) at 60 min before and 5.10 min after the compound 48/80 treatment (8 mg/kg.i.p.) were shown the mortality rates as 0.44.4. and 77.8%. respectively. A 60 min before administered group revealed a singificant inhibition of serum his-tamine release compared with those of 5 and 10 min after the compound 48/80 injection. Eugenol (6-48mM) was also showed a dose-dependent activity on the compound 48/80-induced histamine release from the highly purified population of Alcian Blue-positive peritoneal mast cells. These results indicate that in vitro treatment with exogenous eugenol inhibited the active response of mast cell populations and modulated its characteristics.

        The cutting tests of wood patterns are carried out using CNC milling machine. The cutting forces and surface characteristics of machined surface are investigated at various cutting conditions such as spindle speed, feed speed, cutting direction of wood pattern and wood material. In the CNC end-milling, the surface roughness increases as feed speed increases and decreases as spindle speed increases. However, the cutting force and surface roughness are different along the cutting direction and material of wood pattern.

        김장규,김석형,김태환,이대광,김남기 成均館大學校 科學技術硏究所 1993 論文集 Vol.44 No.1

        It this study, basic data were obtained for the treatment of industrial waste water which includes aromatic compounds. Substrate concentrations used were 100ppm, 500ppm, and 1,000pprn and initial pH's were pH6, pH7, and pH8 in order to obtain the optimum conditions for treating benzoate, m-toluate, and phenol by Pseudomonas putida(KCTC 1644). Durations were 20hrs for 100ppm, 40hrs for 500ppm, and 60hrs for 1,000ppm before the static growth of Pseudomonas putida. 100% of 100ppm benzoate(0.31g cell/1) was biodegraded at pH6, pH7, and pH8 before 20hrs, 52.8% of 500ppm at pH8 in 40hrs, and 27.9% of 1,000ppm at pH8 in 60hrs. The best initial pH was pH8 for the biodegradation and the growth of Pseudomonas putida in benzoate medium. For m-toluate, the best initial pH was also pH8. At this pH, 40.6% of 10Dppm(0.31 cell/1), 21.9% of 500ppm, and 14.1% of 1,000ppm m-toluate were biodegraded respectively in limited time. But for phenol, the best initial pH was pH7. At this point, 9.8% of 100ppm(0.218 cell/1), 7.1% of 500ppm, and 4.7% of 1,000ppm phenol were biodegraded respectively. Therefore, the best carbon source in this experiment was benzoate. Pseudomonas putida was also able to biodegrade m-cresol, p-hydroxybenzoic acid, and benzaldehyde.

        Ocllratoxin A는 fenicl'flrium과 rtsr☞rgiffus 속 등의 곰팡of가 생성하는 mycotoxin으로서 세포매기성 및 체액성 면역기능에 슨상을 일으키는 것으로 알려져 있다. 본 연구는 OTA가 면역계에 미치는 영향과 OTA의 면역 독성 억제 효과가 있는 물질을 검색하기 위하며 6~7 주령의 Balb/c mice 비장세핀에 T 및 B 세포의 mitogen인 Con A와 LPS로 처리하고 3일간 배양한 후 비장세포의 분화정도를 MTS를 처리하여 관찰하였으며, OTA를 투여한 마우스의 면역장기 형리조직학적 견화를 관찰하였다. 마우스의 비장세포 (2xtD6cel1/rnf)에 OTA(1~6μg/ml)를 상에서 혼합하여 Con A와 LPS로 자극시킨 결과 임파구는 Sfg/mf이상에서 거의 모든 세포가 분화되지 않았다. mice에 OTA (1,5 및 10mg/11g)를 2일 간격으로 6회 복갚 주사한 후 비장세포를 분리하여 Con A와 LPS로 처리한 결과 Smg 투여군에서는 6회 투여 혼에 분화가 억제되었고, 10mg 투여군에서는 3회 및 6회 투여군에서 분화가 억제되었단. Ochratoxin A의 면역독성 억제 효과가 있는 물질을 검색하기 위하여 in vitro 실험에서 마우스의 비장세포 (2×10" cell/mf)에 OTA (3fg/mf)와 L-phenylalanine, indole-3-carbinol, L-ascorbic acid,piroxicaTn, curcumin 및 arethylsalicylic acid를 혼합하고 동일 처리한 결과 L-ascorbic acid, L-phenylala-nine 및 Indole-3-carbinol은 OTA의 면역독성 발현을 운의성 있게 억제하였다. Balt/c mice에 OTA (10mg/kg)와 l'n pifro실험에서 억제효파가 확인된 L-ascorbic acfd, L-phenylalanine 및 indole-3-carbinol을 2일 간격으로 동시에 3회 복강주사하여 관찰한 결과 indote-3-carbine께서 엮제효과를 관찰할수 있었다. Ochratoxin A를 투여할 마우스의 비장 및 홍선에서는 임파구의 빈도가 줄었으며 특히 비장제서는 starry-sky 세포가 증가됨을 관찰할 수 있었다. 이러한 결자로 OTA는 비장세포의 T 및 B 임파구의 분열능을 억제시 키며, 면역장기의 임파구에 손상 야기시키므로서 면역기능을 저하시키고 OTA에 의한 면역독성은 indole-3-carbinol이 경감시킴을 관찰하엿다. Ochratoxin A (OTA) is a Tnyeotoxin produced by several fungal species iBcluded the genera fs4pergiffug and f☞HiciHiHuL and known as one of the major environmental contaminants. Tn thepresent study, the effects of OTA on the imraune system and the prevention of the OTA-inducedimmunosuppression by protective agents were studied in Balb/c rnicf:. Splenocytes were isolated and theproliferative responses to concanavalin A (Con A) and lipopolysaccharide (LPS) were measured in thepreseEce of 1 to 6fg/mf OTA. Sfg/mf OTA completely btocked both Con A and LPS-stimulatedmitogenic responses, causing approximately 50% inhibition at 3fe/mf OTA. This suppression of mitogen-induced proliferative resplonses observed id uifro was reproduced in mice treated with ☞rA in rioafntraperitoneal administration of 5, IDmg/kg OTA 3 to etimes every other day significantly decreasedboth Con A- aud LPS-inttuced mitegenic responses. The effects of possible protective agents on theOTA-induced suppression c)』 mitogenic responses were examined both in uifro and in viua Amoag 6 pos-sible protective agents (1,-phenylalanine, L-ascorbic acid, indole-3- carbinol, curcumin, firoxicam,acethylsaricylic acid) employed in the present study, L-phenylalanine (100ff), L-ascorbic acid (100#M) and iBdote-3-carbinel t 10Df) showed significantly protective effects on the OTA-iBduced suppres-sion of mitogenic responses id uifro. Howeuer, when the protective of·fects of these agents were examinedin rr'ua only indole-3-carbinol showed significantly protective respoases. It has been ebserved that Iyin-phatic cell population in thc spleen and thymus was decreased in raice given OTA by hematoBylin-eosinstaining. These data indicate that OTA suppresses the cell-mediated and humoral immune functioBsand this OTA-iBduced supflression of immune functions can he alleviated by indole-3-carbinol.

        Periosteal osteosarcoma is a distinct entity of malignant bone tumor with characteristic clinical, morphological, and histological features within the group of juxtacortical osteosarcoma. Periosteal osteosarcoma is predominantly located in the tubular long bones, and extremely rarely involving the jaws. A case of periosteal osteosarcoma of the right mandible is presented. A 27-year-old woman complained of the gingival swelling and bleeding tendency of the right posterior mandible. Clinical examination revealed a reddish brown strawberry-like swelling on the affected mucosa, which measured 1.5㎝×1.5㎝. The tumor was located on the lingual cortex of the mandible and extended into the surrounding soft tissues. Microscopically, the tumor consisted exclusively of atypical chondroblastic cells with a small osteoblastic area. A minimal bone marrow involvement was noted and the adjacent cortex was free of tumor. These findings suggested that the tumor originated from the periosteal cambium layer, which lies between the periosteal fibrous layer and the cortex of mandible.

        Kim, Seong-Hwan,Seo, Won-Deog,Kim, Ki-Hong,Yeo, Hyung-Tae,Choi, Gi-Hwan,Kim, Dae-Hyun The Korean Neurosurgical Society 2012 Journal of Korean neurosurgical society Vol.52 No.2

        Objective : The purpose of this study was 1) to analyze clinically-executed cervical lateral mass screw fixation by the Kim's technique as suggested in the previous morphometric and cadaveric study and 2) to examine various complications and bicortical purchase that are important for b-one fusion. Methods : A retrospective study was done on the charts, operative records, radiographs, and clinical follow up of thirty-nine patients. One hundred and seventy-eight lateral mass screws were analyzed. The spinal nerve injury, violation of the facet joint, vertebral artery injury, and the bicortical purchases were examined at each lateral mass. Results : All thirty-nine patients received instrumentations with poly axial screws and rod systems, in which one hundred and seventy-eight screws in total. No vertebral artery injury or nerve root injury were observed. Sixteen facet joint violations were observed (9.0%). Bicortical purchases were achieved on one hundred and fifty-six (87.6%). Bone fusion was achieved in all patients. Conclusion : The advantages of the Kim's technique are that it is performed by using given anatomical structures and that the complication rate is as low as those of other known techniques. The Kim's technique can be performed easily and safely without fluoroscopic assistance for the treatment of many cervical diseases.

        Misorientation Characteristics at the Growth Front of Abnormally-Growing Goss Grains in Fe–3%Si Steel

        Tae‑Young Kim,Tae‑Wook Na,Hyung‑Seok Shim,Yong‑Keun Ahn,Yong‑Kwon Jeong,Heung Nam Han,Nong‑Moon Hwang 대한금속·재료학회 2021 METALS AND MATERIALS International Vol.27 No.12

        Penetrating morphologies at the growth front of abnormally-growing Goss grains in Fe–3%Si steel was examined in view ofthe possibility that they are the two-dimensional section of the solid-state wetting (SSW) along the triple junction line. Toobtain the statistically meaningful data, 102 penetrated grain and 204 penetrating abnormally-growing Goss grain morphologieswere examined. The misorientation angles of penetrating and penetrated grains were measured by electron backscattereddiffraction. Among the 102 examined penetrated grain boundaries, none has low misorientation angles less than 15°,whereas 17.2% of the 204 penetrating grain boundaries have low misorientation angles, and 23.5% of them have coincidencesite lattice boundaries. Besides, boundary energies of penetrating Goss grains, which were estimated from misorientationangles of the three grains in the penetrating morphology, satisfied the energetic condition for SSW along the triple junctionline. These results imply that the abnormal grain growth of Goss grains in Fe–3%Si steel occurs by the mechanism of subboundaryenhanced SSW.
