An 51-year-old woman presented with microscopic hematuria without protenuria for long time. Laboratory studies demonstrated the presence of red blood cells in urine, a normal serum IgM level, the absence of antinuclear antibodies, and a normal complement level. Renal biopsy revealed that some glomeruli are enlarged with endocapillary cell proliferation and a few glomeruli exhibit prominent vascular pole of the tufts and segmental increase in mesangial cell and matrix. Immunofluorescence studies demonstrated segmental granular deposits for IgM. Electron microscopy showed well-preserved foot process associated with focal effacement. Biopsy findings were consistent with IgM nephropathy. We present this case to promote understanding of the pathogenesis of IgM nephropathy. (Korean J Nephrol 2002;21(2):317-321)

본 연구는 골절단을 이용한 치아-치조골 분절의 급속 치아이동 후 치수, 치주인대 및 치조골의 변화를 유성견에서 평가하고자 하였다. 하악 제4소구치의 근심, 원심, 치근단 부위에서 피질골을 절단하여 치아-골 분절을 형성하고 하악 제3소구치를 발거하면서 협측, 설측 부위의 피질골을 삭제하였다. 1주 휴지기 부여에 따라 휴지기군과 비휴지기군으로 나누어 치아의존형 견인장치로 6일 동안 견인하고 강화기를 거친 후 0주, 1주, 2주, 4주, 6주, 8주에 희생시켜 치수, 치주인대 및 치조골의 조직 변화를 임상적, 방사선적, 조직학적 및 면역화학적으로 평가하여 다음과 같은 결과를 얻었다. 1. 치아이동 양과 강화기 동안의 조직 치유 양상에서 휴지기 유무에 따른 차이는 없었다. 2. 견인측에서 골형성은 강화기 8주까지 계속되었는데 강화기 1-2주에 가장 활발하였으며 6-8주간의 변화는 적었다. 3. 비휴지기군의 강화기 1주에서 치조골 흡수 및 파골세포 출현, 염증세포 침윤이 가장 많았으며, 특징적으로 파상아세포가 압박측의 치주인대와 치수 내에 나타났다. 4. TGF-β는 치조골의 골기질 및 골모세포, 파골세포, 치수 내 파상아세포에서 강양성 발현을 보인 반면 치수, 백악모세포, 무세포성 백악질에서 경미한 양성 발현을 나타내는 부위 특이성이 있었다. 5. TGF-β는 견인측 치주인대의 치조골에 인접한 혈관 및 치주인대세포, 골모세포에서 강화기 초기 1-2주에 주로 발현되었으며 6주 이후에는 발현이 크게 감소하였다. The movement of tooth-bone segments by osteotomy can simultaneously shift tooth and surrounding alveolar bone in a relatively short period. The purpose of this study was to evaluate the tissue changes in pulp, periodontal ligament, and alveolar bone in rapid tooth bone movement with osteotomy. The mandibular 3rd premolar of a dog was extracted and cortical bones of the buccal and lingual area were eliminated, and then cortical bones around the mesial and distal area of root, and below the root apex of the mandibular 4th premolar were osteotomized. After a one week latency period, a tooth-borne distraction device was activated for 6 days. And pulp, periodontal ligament and alveolar bone were evaluated clinically, radiologically, histologically and immunohistochemically at 0, 1, 2, 4, 6, 8 weeks of the consolidation period and conclusions were reached as follows. 1. Latency period didn't affect total amount of tooth movement and healing process of tissue during consolidation period. 2. Bone formation continued through 8 weeks of consolidation in distracted side, with a high peak at 1-2 weeks, and the lowest at 6-8 weeks of consolidation. 3. At 1 week of consolidation, alveolar bone resorption, osteoclast appearance and inflammatory cell infiltration were the most active, and dentinoclasts characteristically appeared on the pulp and pressure side of the periodontal ligament. 4. The expression of TGF-β was area-specific, as it was strong-positive at bone matrix, osteoblast, osteoclast of alveolar bone, and dentinoclast inside pulp, but weak in pulp, cementoblast and acellular cementum. 5. The expression of TGF-β was generally observed at the initial 1-2 weeks of consolidation at vessels, periodontal ligament cells, and osteoblast near alveolar bone on the distraction side of the periodontal ligament, and was significantly decreased after 6 weeks of consolidation.

This study was conducted by critical review analyzing literatures of theories focused on changes of health behaviors. 5 theories-TRA, HBM, Self-Efficacy, Social Support, and Locus of Control-were selected among many theories of health behaviors. Theories were summarized, and models and concepts of theories were described. The results of this study were follows : 1. health behaviors could be classified into preventive behaviors and curative behaviors. 2. Most conceran of previous studies in this field was on health behavior execution itself or on its outcome. 3. the focus of previous studies was on initiation, maintenance, facilitation, and change of preventive and curative behaviors. 4. Factors affecting on health behaviors were demographic factors as exogenous variables and intrapsychic and extrapsychic factors as endogenous variables. 5. Previous studies tested predictability and explicability of these theories onhealth behaviors and identified factors affecting health behaviors most. 6. concepts of TRA, SELF-Efficacy, and Social support had higher explicability on health behaviors than concepts of HBM and Locus of control. From results of this study, we suggested the direction and considerations for futher nursing studies related with these theories. And we derived testable propositions from relationship between concepts and each others.

정확한 Closed-Form 그린함수를 이용한 코플래너 도파로 불연속 해석

강연덕,송성찬,이택경 한국항행학회 2003 韓國航行學會論文誌 Vol.7 No.2

실수축 상의 적분 방법에 의한 정확한 closed-form 그린함수를 이용하여 코플래너 도파로의 불연속에 대한 공간영역 full-wave 해석을 하였다. MPIE(Mixed Potential Integral Eqution)를 풀기 위한 수치계산 방법으로는 삼각형 요소를 이용한 갤러킨 방법을 사용하였다. 경계면에서 삼각형 요소상의 기저함수로는 선형함수를 사용하였으며, 관측점과 전원점이 일치하는 특이점 근방의 적분 계산을 위해 면적분을 선적분 형태로 바꾸어 피적분 함수의 특이점이 사라지도록 하는 해석적인 방법을 사용하였다. 실수축 적분방법에 의한 그린함수를 이용함으로써 불연속에 대한 정확한 특성을 구하였다. By using accurate closed-form Green's functions obtained from real-axis integration method, the full-wave analysis of CPW discontinuities are performed in space domain. In solving MPIE(Mixed Potetial Integral Equation), Galerkin's scheme is employed with the linear basis functions on the truangular elements in air-dielectric boundary. In the singular integral arising when the observation point and source point coincides, the surface integral is transformed into the line integral and the integral is evaluated by regular integration. By using the green's function from the real-axis integration method, the discontinuities are characterized accurately.
