정주영 국립특수교육원 2004 특수교육연구 Vol.11 No.2

이 연구는 정신지체 학생을 담임하고 있는 초등학교 통합학급 교사들이 지닌 통합교육과 교수적합화에 대한 인식과 교수적합화 실제를 조사하여 정신지체 학생이 일반교육과정에 참여할 수 있도록 하기 위해 통합학급 교사에게 구체적으로 어떻게 지원해야 활 것인가를 규명하는데 목적이 있다. 이를 위해 현재 정신지체 학생을 담임하고 있는 서울시 소재 초등학교의 교사 89명을 대상으로 통합교육과 교수적합화에 대한 인식과 실제를 묻는 설문지를 배포하고 결과를 분석하였다. 연구 결과, 첫째, 교사들은 정신지체 학생의 통합교육에 대해 적극적인 긍정적 반응을 보이지 않았다. 둘째, 교수적합화에 대해 긍정적으로 인식하고 있지만, 자신의 교수적합화 수행 가능성은 낮게 평가하였고, 교수적합화의 주체가 아닌 보조자로서 역할을 기대했다. 셋째, 교수적합화 실제에서 학생들의 교실 내 행동을 적절하게 관리하고 있었으나, 교육과정 운영 면에서는 일관성이 결여된 반응을 보여주었다. The purpose of this study was to investigate regular teachers' awareness and practice on inclusion and instruction for students with mental retardation in inclusive settings. 89 teachers in inclusive elementary school completed a questionnaire eliciting their awareness and practice on inclusion and instruction for students with mental retardation. Primary findings included: (a) teachers were not positively aware of inclusion of students with mental retardation, (b) teachers were positively aware of instructional adaptation for students with mental retardation. But, they perceived them to be poor teachers for instructional adaptation and only supports for inclusive education, (c) teachers appropriately managed classroom behaviors of students with mental retardation. But, they didn't adapted curriculum for students with mental retardation in inclusive settings.

유암종은 전신에 퍼져 잇는 장크롬친화성 세포에서 기원하는데 위의 유암종은 비교적 드문 질환으로 모든 유암종의 1.9~2.2%에 해당하며 위에 발생하는 종양의 1% 미만에서 보고되고 있다. 유암종은 일반적으로 증상이 비특이적이고 면역조직화학검사에 의해서 진단되기 때문에 과거에는 드물게 발견되었으나 최근 내시경 기기 및 술기의 발전과 검사 빈도의 증가 및 면역조직화학검사의 발달로 진단율이 증가 추세에 있으며, 드물지만 유암종에서 선암과 공존하는 예들이 보고되고 있다. 저자들은 심와부 동통을 주소로 내원한 70세 남자 환자의 상부위장관내시경 검사에서 위체상부의 대만곡에서 0.4×0.4 cm 크기의 중간 함몰을 가진 Yamada 1형의 용종과 함께 전정부의 전벽에서 0.8×0.5 cm 크기의 융기된 점막 소견을 보여 조직학적으로 각각 위유암종 및 위선종임을 확진한 후 내시경적 용종 절제술로 치료한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Carcinoid tumors are arisen from enterochromaffin cells, which are scattered throughout the body. These tumors are composed of variable numbers of cells that contain endocrine granules in their cytoplasm, which can be identified by immunohistochemistry and electron microscopy. Gastric carcinoid tumors are relatively rare tumor, the reported incidence being 1.9~2.2% of all carcinoid tumors and less than 1% of all gastric tumors. Sometimes, composite carcinoid tumors and adenocarcinoma is reported. We experienced a case of the coincidence of carcinoid tumor and adenoma at the other site of the stomach in a 70 year old male patient. Gastrofiberscope showed 0.4×0.4 cm sized Yamada type I polyp with central depression on the greater curvature of the proximal body and 0.8×0.5 cm sized focal slightly elevated mucosa on the anterior wall of the antrum. The endoscopic biopsy specimens revealed carcinoid tumor and tubular adenoma with moderate atypism, respectively. The carcinoid tumor and adenoma were removed by endoscopic polypectomy. According to the follow-up gastrofiberoscopy after 7 month later, both lesions were nearly normal mucosa except whitish atrophic change after polypectomy.

Ionized Calcium 과 Chitosan 정제의 안정성에 관한 연구

장윤정,김현주,김영일,양재헌 又石大學校 1998 論文集 Vol.20 No.-

Recently, chitosan has being fiocused on not only the role of a potential and natural resource with antibacterial or antifungal effect but also the natural controller of releasing of drugs or principle actives. Calcium is one of the most important minerals of human that concerned with the intra-or inter-cellular function. But ionized calcium, prepared from shell through the condition of high temperature, own the antibacterial effects. We prepared the mixed tablet of chitosan and ionized calcium with several additives such as starch paste, ethylcellulose(EC), hydroxypropylmethylcelullose(HPMC) or hydroxyprophylcellulose(HPC). Each formulation with a additive was adopted as a challenger to modify of release profiles of calcium. Finally following both cationic properties, chitosan & ionized calcium, the mucoadhesive effects in the oral cavity are favorable to introduce for chewable tablet. The similar patterns of contents of calcium, disintegration time, hardness, weigth variation were showed following the preparation with each additive. The dissolution profiles of starch paste preparation was more slower than other preparations. It was as the order as HPMC, HPC, EC. The stabilities of tablet of each formulation was creditable in the period of 4 weeks under the condition of 50℃ and 75% of humidity. The contents of calcium, disintegration time, hardness were not changed significantly. Ionized calcium and chitosan mixed tablet may increase the antibacterial effects and the release patterns of calcium could changed successfully by several addives.

Background/Aims: Retroperitoneal fibrosis is a fibrosing disease process which frequently develops ureteral obstruction. Malignant retroperitoneal fibrosis has been reported that various types of cancer including cancer of the breast, stomach, prostate, lung, cervix, uteri, colon, pancreas, ovary, and even Hodgkin's disease. While the pathogenesis remains obscure, small foci of metastatic neoplasm in the retroperitoneal space can elicit a desmoplastic reaction in secondary form to malignancy. Methods: Recently we experienced 7 cases of retroperitoneal fibrosis with advanced gastric cancer. So, we report 7 cases of retroperitoneal fibrosis with clinical and radiologic characteristics. Results: The most common signs and symptoms were related irreversible renal dysfunction. The urologic finding noted medial deviation of the involved ureters and hydronephrosis Conclusions: Clinical manifestations are abdominal pain, back pain, hydronephrosis, and uremia. When sudden back pain and hydronephrosis develop in advanced malignancy, physicians should be considerd for retroperitoneal fibrosis.

PDP 방법에 따른 표절 유사도의 신뢰성에 관한 연구

장주현,노희영 강원대학교 정보통신연구소 2008 정보통신논문지 Vol.12 No.-

Recently, many software-programs are being plagiarized. Therefore a study on the prevention against plagiarism needs in aspect of information protection. Generally there are two methods to find out the plagiarism. The one lies in comparison with tokens of the source programs, and the other depends on structural similarity that analyzes the programs into control structures. This paper attempted to proof of objective reliability of the PDP method that measures the structural similarity of plagiarism in object-oriented program. Hence this paper presented the NCT method that improves the reliability through direct participation in decision for the structural similarity of program, and attested to the reliability of PDP method in comparison with similarity of two methods
