이영미,최항문,허민석,이삼선,최순철,박태원 대한구강악안면방사선학회 2000 Imaging Science in Dentistry Vol.30 No.3

Purpose : The study was aimed to detect the induction of apoptosis, cell cycle arrest and calcified nodule formation after irradiation on primarily cultured osteoblasts. Materials and Methods : Using rat calvarial osteoblasts, the effects of irradiation on apoptosis, cell cycle arrest, and calcified nodule formation were studied. The single irradiation of 10 and 20 Gy was done with 5.38 Gy/min dose rate using the 137Cs cell irradiator at 4th and 14th day of culture. Apoptosis induction and cell cycle arrest were assayed by the flowcytomtry at 1,2,3, and 4 days after irradiation. The formation of calcified nodules was observed by alizarin red staining at 1,3,10,14 days after irradiation at 4th day of culture, and at 1,4,5 days after irradiation at 14th day of culture. Results : Apoptosis was not induced by 10 or 20 Gy independent of irradiation and culture period. Irradiation did not induced Gl arrest in post-irradiated ostedblasts. After irradiation at 4th-day of culture, G2 arrest was induced but it was not statistically significant after irradiation at 14th-day of culture. In the case of irradiated cells at 4th day of culture, calcified nodules were not formed and at 14th-day of culture after irradiation, calcified nodule formation did not affected. Conclusion : Taken together, these results suggest that Irradiation at the dose of 10-20 Gy would not affect apoptosis induction of osteoblasts. Cell cycle and calcified nodule formation were influenced by the level of differentiation of osteblasts. (Korean J Oral Maxillofac Radiol 2000; 30: 189-198)

목적: hNIS는 갑상선 조직 외에 다른 조직들에서도 발현된다고 알려져 있다. 유방암 세포는 그런 조직들 중에 하나이며, 그에 의한 유방암의 방사성옥소치료의 가능성이 제시되고 있다. 본 연구에서는 유방암 조직에서 hNIS의 발현정도를 알아보고, ^99mTc-MIBI 유방스캔과 hNIS의 발현 정도와의 관계를 조사하여 보았다. 대상 및 방법: 본 연구에서는 유방암으로 수술을 시행했던 56명의 환자를 대상으로 하였다. hNIS의 발현은 면역조직화학염색에 의해서 평가되었으며, 그 결과를 ^99mTc-MIBI 유방스캔의 판정 결과와 비교하였다. 결과: 전체 56명의 환자에서 hNIS의 발현율은 41.1%였다. 병리학적 진단에 의해 침윤성관상피암종이었던 49명에서의 발현율은 42.9%, 관상피내암종이었던 7명에서의 발현율은 28.6%였다. ^99mTc-MIBI 유방스캔에서 국소섭취 소견이 관찰되었던 41명에서의 hNIS의 발현율은 31.7%였다. 비정상적인 섭취 소견이 관찰되지 않았던 15명의 환자에서의 hNIS의 발현율이 의미있게 높게 관찰되었다(66.7%, p>0.05). 결론: 유방암 환자에서의 hNIS의 발현율은 그다지 높지 않았다. ^99mTc-MIBI 유방스캔에서 섭취증가 소견이 없을 때 hNIS의 발현율이 더 높았다. Purpose: Human Na^+/I- symporter (hNIS) is known to be expressed in many tissues other than thyroid gland. The breast cancer cells are one of them and the possibility of radioiodine therapy in treatment of the breast cancer may be suggested. We investigated the expression rate of hNIS and the relationship between the expression of hNIS and the finding of 99mTc-MIBI scintimammography in the breast cancer. Materials and Methods: Surgically proved 56 patients with breast cancer were the subjects of this study. The expression of hNIS were evaluated by immunohistochemistry and the results were compared to the findings of 99mTc-MIBI scintimammography. Results: Overall expression rate of hNIS was 41.1% in 56 patients. According to the pathologic diagnosis, it was 42.9% in 49 patients with invasive ductal carcinoma and 28.6% in the 7 patients with ductal carcinoma in situ. The expression rate of hNIS in the 41 cases with a focal increased uptake at he breast lesion on 99mTc-MIBI scintimammogram was 31.7%. That in the 15 cases without any abnormal uptake on the scan was significantly higher(66.7%, p<0.05). Conclusion: The expression rate of hNIS in the patients with breast cancer was not so high. The rate was higher in the patients with no increased uptake at the breast lesion on 99mTc-MIBI scintimammography. (Korean J Nucl Med 2002;36;325-32)

본 연구에서는 3차원 정육면체 가열로 내의 전도-대류-복사 복합열전달 특서을 해석하였으며, 연소가스의 유입속도, 벽면의 반사율과 매체의 흡수계수 등과 같은 인자들의 변화에 따른 영향을 살펴보았다. 가열로의 벽면들은 단열되어 있고 가열로 내부로 일정한 온도의 연소가스가 유입될 때 시스템 내부의 온도는 유입 온도와 비슷하게 균일한 온도 분포를 갖는 것으로 예측할 수 있었다. 유입 속도가 증가하더라도 가열로 내부의 온도에는 거의 영향을 미치지 않았으며, 가열로는 유입되는 연소가스의 흡수계수가 증가할수록 가열로 내부의 온도는 보다 균일하게 된다. 또한, 가열로 내부 벽의 반사율이 커질수록 벽의 온도는 감소하고 또한 벽면에 작용하는 유효복사열유속은 증가함을 알 수 있었다. 이러한 해석 결과로부터 가열로 내부의 온도 분포는 매체의 흡수계수가 클수록 그리고, 벽면 반사율이 작을수록 일정하게 유지될 수 있다는 것을 알 수 있었다. 그리고 이러한 결과들을 종합하여 볼 때 가열로의 설계 시 일정한 열의 유입과 가열로를 단열시키는 것이 중요하며, 그리고 매체의 흡수 계수를 크게 하고, 그리고 벽면의 반사율을 작게 하는 것은 가열로 내부의 온도를 일정하게 유지할 수 있는 중요한 조건이 된다는 것을 알 수가 있었다.

인터넷은 디지탈 형태의 다양한 정보를 신속하게 전달한다는 점에서 매우 각광을 받고 있다. 그러나, 대량의 인터넷 정보 중에서 자신이 원하는 정보 자원을 정확하게 많이 얻어 낼 수 있는 방법의 제공은 매우 어려운 문제이다. 본 논문에서는 인터넷 정보 자원의 메타데이타를 관리하기 위해 SeriCore라는 SGML 형식의 메타데이타 DTD(Document Type Definition)를 정의하고, 이들 메타데이타를 효율적으로 저장하고 검색, 관리할 수 있는 시스템을 설계, 구현하였다 The Internet has gained popularity because ot provides various information in digital format. However, it is very difficult to provide methods which make it possible to search adequate information resource from bulk of Internet information. In this paper, we define a SGML metadata DTD, named SeriCore, and design and implement a metadata retrieval and management system which can store, retrieve and manage the Internet metadata efficiently

영종도지역 해성점토의 공학적 특징

홍원표,송영석 중앙대학교 기술과학연구소 2001 기술과학연구소 논문집 Vol.31 No.-

영종도지역의 해성점토를 대상으로 실시된 토질물성시험과 전단시험결과의 분석을 통하여 이 지역 토질의 물리적 특성과 역학적 특성이 고찰된다. 본 지역의 지층은 지표면에서부터 해성퇴적층, 풍화잔류토층, 풍화암층 및 연암층으로 구성되어 있으며, 해성점토층은 통일분류법 상 CL, ML 및 CH로 분류된다. 해성점토의 물리적 특성은 액성한계와 소성한계, 자연함수비, 초기간극비 및 단위중량과의 상관관계를 통하여 알 수 있다. 그리고, 해성점토의 역학적 특성은 변형특성과 강도특성으로 구분하여 나타낸다. 변형특성은 Janbu(1963)에 의해 제안된 초기탄성계수와 구속압의 관계로 설명할 수 있으며, 강도특성은 Mohr원으로부터 유도된 유효내부마찰각과 Lade(1988)에 의해 제시된 강도정수를 구하여 설명할 수 있다. 한편, Rutledge에 의해 제안된 함수비에 따른 최대축차응력과 압밀응력의 관계를 조사한 결과 전단강도와 함수비는 압밀응력에 의존하며 유일함수의 관계가 있음을 알 수 있다. In this study, the both physical and mechanical properties of marine clays in Youngjong Island are investigated from the laboratory tests such as Atterberg limits test, water content test, triaxial test, and so on. The soil deposit just below the ground surface is marine sediment soils, weathered soils, weathered rock and soft rock. The marine clays are classified in three types such as CL, ML and CH by the unified classification system. The physical properties of marine clays can be explained by investigation of the relationships among liquid limit, plastic limit, water content, initial void ratio and unit weight. The mechanical properties are divided into the two types of deformation properties and strength properties. The deformation properties can be explained by the relationship between the initial tangent modulus and confining pressure proposed by Janbu(1963). Also, the strength properties can be explained both angle of internal friction derived from Mohr circle and shear strength parameters proposed by Lade(1988). Rutledge hypothesis is confirmed from the relationships among maximum deviator stress, consolidation stress and water content.
