Assessment of residual stress is an important point to prevent the failures of thin film devices. Nanoindentation technique was proposed as a stress-measuring method of thin film in a previous research. However, the stress-analyzing model used at the previous research had the problems of a partial deformation-irrelative stress interaction concept and no consideration of the change in the contact area during continuous stress relaxation. Therefore, we modified the model by analyzing a new residual stress-induced normal load based on deformation-dependent shear stress component and by calculating the continuous relaxation procedure as an integration method. The modified model was applied to evaluate the residual stresses in two diamond-like carbon films. The evaluated residual stresses from the newly modified model were more consistent with the results from the conventional curvature method than those from the earlier model.

Apparent mechanical properties of welded structural components are deviated from the initially designed values due to the residual stress. Thus, exact assessment of the residual stress using a nondestructive method became an important issue in reliability researches. A nanoindentation model for evaluating the equi-biaxial thin film residual stress was proposed in the previous study. However, the surface residual stress in the welded joint is a non-equi-biaxial state and complex elastic/plastic deformations are involved in the macroindentation. Therefore, the previous model was modified to evaluate the real non-equi-biaxial residual stress by considering a new stress-proportional factor and a significant effect of the plasticity. The newly modified stress-analyzing model was verified empirically by comparing the evaluated uniaxial stress with the already known residual stress of 4-point bended specimen.

Background : Pneumocytitis cainii pneumonia (PCP) can occur in immunocompromised hosts especially such as AIDS or cancer patients. Although recent research had focused on PCP in AIDS patients, few studies have described the clinical presentations of PCP in recipients of stem cell transplantation (SCT). We evaluated the clinical manifestations of PCP in SCT patients admitted at St. Mary's hospital, Seoul, Korea. Methods : The medical records of 17 PCP patients undergoing SCT between Feb. 1998 and Feb. 2000 were reviewed. The diagnosis of PCP was confirmed through the demonstration of Pneumocytitis cainii via either cytology of brochoalveolar lavage (BAL) or histological technique of lung biopsy. CMV disease and CMV infection were confirmed by BAL culture and antigenemia respectively . Results : Seventeen patients were all recipients of allogeneic SCT and 7 of 17 patients were performed non-sibling SCT. Patients presented with symptoms including brief period (4 ∼23 days) of fever (76%), dyspnea (70%), cough (64%), and signs such as rare(58.8%), Sixteen patients (94%) had been receiving immunosuppressive agent such as cyclosporine A (64%) or Fk506 (35%) without PCP prophylaxis. Eleven patients (64%) were treated with corticosteroid with mean dose of 16 mg/day prednisolone and mean duration of 4.6 months after post-SCT period. Twelve patients were co-infected with CMV. Another co-infected miCroorganisms were Pseudomonas aeruginosa, Mycobacterium tuberculosis, herpes simplex virus, parainfluenza virus, Average duration of treatment with trimethoprim-sulfamethoxazole (TMP/SMX) was 21 ±9 days. Four patients died, and three of them were related with PCP. Conclusion : PCP developed frequently in patients who were taking immunosuppressive drug due to graft versus host disease or were not taking TMP/SMX prophylaxis. High risk patients showing fever, cough, or dyspnea should be considered to take early bronchoscopic intervention for detection of PCP. When treat for PCP, it also be considered to the possibility of coinfection such as CMV. (Korean J Infect Dis 33:273∼279, 2001)

조윤주,최지희 慶星大學校 1999 論文集 Vol.20 No.2

The purpose of this report is to observe the effect of the residential planning in Bauhaus workshop education which is based on design curriculum The results are as follows ; First, the production of Wassily chair designed by Marcel Breuer changed the conception of the furniture. The assembling and the dismantling of the furniture were realized by that change. Second, Marcel Breuer suggested the duality of residential planning. For example, he established the definition of the characteristics in construction system between the architecture and the environment, that is, supporting and load, form and space, color and surface, compression and tension. Third, The educated by Bauhaus developed curtain-wall construction technique which is covered with all glasses all over the building surface composed of the workshop assimilation of mental and lighting with the furniture. That residential building planning was clear from the representative optical expression in modern architectural evaluation, mutual penetration and polyhedralness.

소아치과학이 목표로 하는 어린이와 청소년의 구강건강을 달성하기 위하여는 민간 치과의료기관에서 내원 환자를 대상으로 하는 진료만으로는 한계가 있으며 공공서비스(公共service)의 역할이 필요하다. 학교구강보건설이 설치된 초등학교는 전체의 7.2%이었고,초등학교 중에서 불소용액양치사업을 수행한 비율은 57.5%, 급식 후 집단잇솔질을 한 비율은 46.9%이었으며,초등학생 중에서 구강보건교육을 받은 비율은 48.0%, 치아홈메우기를 받은 비율은 12.4%이었다(2006년). 0∼6세 영유아의 약 42%가 지난 1년간 구강검진,불소도포,치면세마,치아홈메우기 중 하나 이상의 예방적 치과진료를 받았으며,받은 장소는 교육시설이 약 18%, 보건소가 약 1%이었다(2005년). 불소농도가 조정된 수돗물을 마시는 인구 비율은 전국 평균이 5.7%이었다(2006년). 학교구강보건사업의 발전을 위해서 행정의 일원화,보건교사에 대한 교육,구강보건교사제도의 도입,순회 학교치과의사와 학교치과병원을 통한 포괄적 진료서비스의 제공 등을 고려할 수 있을 것이다. 또한 아동·청소년 주치의제의 도입으로 민간기관을 통해 공공서비스를 강화하는 방안이 검토되고 있다. To achieve the dental health of children and adolescents which is the objective of the pediatric dentistry, the role of the public service should be increased. The basis of the public service is established by many laws of which the Dental Health Law is most important. The percentages of primary schools that had the school dental health clinic, that implemented the fluoride rinsing program, and that implemented the group toothbrushing after lunch were 7.2%, 57.5%, and 46.9%, respectively, and the percentages of primary school children that received the dental health education and that received the fissure sealing were 48.0% and 12.4%, respective1y(2006). About 42% of infants and preschool children from 0 to 6 years received preventive dental care in the last one year, at the nursery or kindergarten(18%) or at the health center(1%)(2005). The percentage of the health centers that implemented water fluohdation was 11.3%, and the percentage of the population who drank the fluoridated water was 5.7 %(2006). It was suggested that the school dental health administration should be unified, that dental health teachers should be employed, and that the comprehensive dental health care should be supplied to all the children and adolescents through the circuit school dentists and the school dental hospitals in the long term. Also, the dentist in charge system for the children and adolescent was suggested.

브라켓과 호선 간에 발생하는 마찰은 치아 이동의 효율에 상당한 영향을 미친다. 마찰력에 기여하는 요소 중 특히 브라켓과 호선의 표면조도는 중요한 요소이다. 본 연구는 브라켓과 탄선을 실험적으로 마찰시킨 후, 원자현미경 (atomic force microscope, AFM)을 사용하여 브라켓 슬롯과 교정용 탄선의 표면 조도 변화를 정성적, 정량적으로 측정하고 비교 평가하여 브라켓과 호선 간의 마찰이 각각의 표면 변화에 미치는 영향을 규명하고자 시행되었다. 스테인리스 스틸 브라켓과 세라믹 브라켓에 각각 스테인리스 스틸 탄선과 TMA 탄선을 실험적으로 활주마찰시킨 후 각각을 원자현미경을 이용하여 표면을 관찰하였다. 실험결과 브라켓보다는 교정용 탄선에서 활주마찰 후에 더 많은 표면 변화가 나타났다. 또한 활주마찰 후에 스테인리스 스틸 브라켓은 표면 조도의 유의한 변화가 없었으나 세라믹 브라켓은 표면 조도가 감소하였다. 그리고 교정용 탄선은 모두 활주마찰 후에 표면 조도가 증가하였으며 이러한 표면 변화는 스테인리스 스틸 브라켓보다 세라믹 브라켓과의 활주마찰 후에 더 큰 것으로 관찰되었다. 본 실험으로 원자현미경은 브라켓 슬롯과 탄선의 표면 조도를 정량적으로 측정하는 데에 유용한 수단임을 알 수 있었다. Objective: The surface roughness of orthodontic materials is an essential factor that determines the coefficient of friction and the effectiveness of tooth movement. The aim of this study is to evaluate the surface roughness change of the brackets and wires after experimental sliding quantitatively. Methods: Before and after experimental sliding tests, the surface roughness of stainless steel brackets, ceramic brackets, stainless steel wires, and beta-titanium (TMA) wires were investigated and compared using atomic force microscopy (AFM). Results: After sliding tests, changes in the surface of the wire were greater than changes in the bracket slot surface. The surface roughness of the stainless steel bracket was not significantly increased after sliding test, whereas the roughness of ceramic brackets was decreased. Both the surface roughness of stainless steel and TMA wires were increased after sliding test. More changes were observed on the ceramic bracket than the stainless steel bracket. Conclusions: AFM is a valuable research tool when analyzing the surface roughness of the brackets and wires quantitatively.

김수연,김진용,강지혜,박신영,이희승,박윤수,서일혜,조용균 대한감염학회 2007 감염과 화학요법 Vol.39 No.4

목적 : 본 연구는 일개 대학병원의 한 병동에서 16SrRNA 유전자 염기서열 분석을 통해 확인된 Acinetobacter spp. 가성요로감염 집단 발생에 대한 조사이다. 재료 및 방법 : 일개 대학병원의 일반병동에서 2005년 9월 23일부터 26일까지 5명의 환자에서 Bordetelta bronchiseptica 세균뇨가 동시에 분리되었다. 해당 환자들에 대한 입원 진료 기록을 확인하고, 이학적 검사를 시행하였고, 의료진 면담 등의 역학적 조사와 의심되는 전파원의 환경 감시배양을 시행하였다. 또한 다섯 균주들의 상동성 확인을 위해 pulsed field gel electrophoresis (PFGE)를 하였고, 정확한 균 동정을 위해 16S rRNA 유전자 염기서열 분석을 하였다. 결과 : VITEK system에 의해 B. bronchiseptica로 보고된 다섯 균주들은 거의 유사한 항생제 감수성을 가지고 있었다. 유행조사에서 요로감염의 증상이나 균혈증을 보인 환자는 없었고, 환경 감시배양에서 공통의 전파원은 증명되지 않았다. 또한 PFGE와 16S rRNA 유전자 염기서열분석에서 상동성을 가진 동일 Acinetobacter spp.로 확인되어 이에 의한 가성요로감염의 유행으로 결론지었다. 결론 : 역학적 조사와 함께 PFGE와 16s rRNA 유전자염기서열 분석과 같은 분자생물학적인 조사를 시행하는 것은 희귀한 균에 의한 병원감염 유행조사에 도움이 될 것이다. Background : Acinetobacter spp. is increasingly implicated in hospital-acquired infections. We experienced a pseudooutbreak of Bordetella bronchiseptica bacteriuria identified with biochemical tests, that was later identified as Acinetobacter spp. by using 16S rRNA gene sequence analysis. Materials and Methods : Five in-ward patients were found to have B. bronchiseptica bacteriuria without symptoms of urinary tract infection between September 23 and 26 of 2005. We conducted pulsed field gel electrophoresis (PFGE) of the bacteria and epidemiological investigation of this pseudooutbreak. In addition, 16S rRNA gene sequence analysis was performed for the verification of the strains. Results : All 5 isolates were identified as B. bronchiseptica with similar antibiogram by VITEK system. There was no evidence of any symptom or sign of urinary tract infection. The source of this pseudooutbreak was not detected even after performing environmental culture and interviews with healthcare workers. We could not get the appropriate results from the first PFGE with XbaI restriction enzyme. B. bronchiseptica is an unusual organism in human so we conducted 16S rRNA gene sequence analysis for verification. The analysis of 16S rRNA gene sequence with 5 isolates demonstrated 99-100% similarity to a sequence of Acinetobacter spp. (AU1523). According to the results of 16S rRNA gene sequence analysis, we performed the second PFGE with SmaI restriction enzyme, which showed indistinguishable pattern among the all 5 isolates. Conclusion : This investigation suggests that the combined method of 16s rRNA gene sequence analysis and PFGE would be helpful for investigation of outbreak caused by unusual organisms.
