In order to investigate the effect of rapid solidification on the microstructure and the mechanical properties of Al-Zn-Mg system alloys, water atomization was carried out, since the water atomization beared the highest solidification rate among the atomization processes. The as atomized alloy powders consisted of fine grains less than 4 ${\mu}m$ in diameter, and the second particles were not detected on XRD. The microstructure as solidified was maintained even after the spark plasma sintering at the heating rate of 50 K/min. On the other hand, lower rate of 20 K/min induced a formation of $MgZn_2$ particles, resulting in strengthening of the matrix. The density was almost constant at the temperature above 698K. The sintering temperature above 698K had no effect on the strength of the sintered materials.

김선미,Kim, Seon-Mi 대한영상의학회 2004 대한영상의학회지 Vol.50 No.3

D-penicillamine은 구리를 킬레이팅(chelating) 시키는 약물로 윌슨씨 병 치료등에 이용되고, 드문 합병증으로 유방 확대가 나타날 수 있다. 본 증례는 윌슨씨 병 치료를 위해 10개월간 D-penicillamine을 사용한 환자에서 유방확대가 발생한 경우로 유방 촬영술에서 양측 유방의 확대와 치밀유방의 소견을 보였다. 또한 초음파검사에서 양측 유방의 확대와 왼쪽 유방에 결절이 관찰되었지만 조직 검사상 악성의 소견은 없었다. D-penicillamine, a chelating agent of copper, is the drug of choice for the treatment of Wilson’s disease. Breast enlargement is a rare complication arising from its use, and we report a case of breast gigantism which developed after it had been used for ten months to treat this condition. Mammography demonstrated bilaterally enlarged dense breasts; ultrasonography, similarly, demonstrated enlargement, revealing the presence of a mass, shown at biopsy to be benign, in the left one.

김선미,김표년,하현권,Kim, Seon-Mi,Kim, Pyo-Nyeon,Ha, Hyeon-Gwon 대한영상의학회 2001 대한영상의학회지 Vol.45 No.4

Purpose: Mucosal surface nodularity was defined as present at UGIS when multiple nodular defects larger than 5 mm were scattered in the gastric mucosa in an area greater than 5 $\times$5 cm. The purpose of this study was to determine the primary causes of this radiographic finding and to assess the incidence of gastric malignancy in these patients. Materials and Methods: During a one-year period we prospectively collected among patients who underwent UGIS, data for 51 [aged 30 -78(mean, 51) years] above who met the criteria of mucosal surface nodularity. Whether or not this was present was decided by two radiologists who in reaching a consensus excluded the possibility of erosive gastritis, indicated by central barium collection in the nodular defects. The primary causes of mucosal nodularity and associated gastric pathologies were determined by the histopathological results obtained from the specimens after surgery (n=18) or endoscopic biopsy (n=33). Results: Pathological examinations revealed that the primary causes of the mucosal nodularity in these 51 patients were intestinal metaplasia in 28 (54.9%), MALT lymphoma in seven (13.7%), early gastric cancer in six (11.8%), chronic gastritis in five (9.8%), low grade dysplasia in four (7.8%), and gastritis cystica profunda in one (2%). Gastric malignancy was present either in or outside the area of mucosal nodularity in 34 (66.7%) of the 51 (27 carcinomas and 7 MALT lymphomas). No different patterns of mucosal surface nodularity were noted between the groups of each disease entity. Conclusion: Mucosal surface nodularity is observed at UGIS in various gastric pathologies. Because of the high incidence of gastric malignancy in these patients, close follow-up or gastrofiberscopic biopsy is mandatory. 목적:상부위장관조영술에서 5 mm 이상의 다발성 결절성 결손이 5 $\times$5 cm이상의 면적에 산재해 있을때를 위점막표면결절화로 정의하고 이런 소견을 보이는 일차 원인질환들을 전향적으로 분석하고 아울러 위암의 병발율을 알아보고자 하였다. 대상과 방법:1년동안 본원에서 상부위장관조영술을 시행받은 환자중 위점막표면결절화를 보인 환자 51명을 대상으로 하였다.두명의 방사선과 의사가 합의하에 위점막표면결절화의 유무를 판단하였고 결절 결손부위에 바륨이 집적되는 미란성위염은 제외하였다.위점막표면결절화의 일차성원인은 수술 (n=18)및 내시경적 조직생검 (n=33)으로 진단하였는데 상부위장관조영술에서는 위점막표면결절의 형태,주름변화,결절의 크기,및 병변의 분포에 대하여 분석하였다. 결과:위점막표면결절화의 일차 원인질환으로는 장화생(intestinal metaplasia)28예 (55%),점막관련림프조직 림프종 7예 (13.7%),조기위암 6예 (11.8%),만성위염 5예 (9.8%),저이형성(low grade dysplasia)4예 (7.8%),및 심재성 낭성위염(gastritis cystica profunda)1예 (2%)였다. 이들 환자들에서 위점막표면결절화를 보이는 부위 또는 그 외의 부위에서 악성병변으로 확진된 예는 51명중 34명으로 67%였는데 27예에서 위선암이었고 7예에서 점막관련림프조직 림프종이었다.점막표면결절화를 보이는 질환군간에는 방사선학적 소견의 차이는 보이지 않았다. 결론:상부위장관조영술상에서 위점막표면결절화를 보이는 원인질환은 다양하다.원인질환의 양성,악성여부를 감별하거나 특이적 진단을 하는데는 상당한 제한점이 있지만 많은 수의 환자에서 악성병변이 원인질환임을 알 수 있었다.따라서 위점막표면결절화의 방사선학적 소견에 익숙해지는 것이 정확한 진단뿐 아니라 결절화의 범위를 결정하고 추가검사를 권유하는 등의 진단적 가치를 높일수 있다.

가상박물관 활용을 통한 박물관 전문인력의 디지털 역량 강화 방안 연구

김선미,이종욱,Kim, Seon-Mi,Lee, Jong-Wook 한국콘텐츠학회 2022 한국콘텐츠학회논문지 Vol.22 No.10

The overall digital transformation in society is rapidly progressing with the corona virus epidemic. In particular, in the field of cultural heritage and museums, digital transformation is taking place throughout the preservation, management, and utilization of cultural heritage. To respond to this, the importance of cultivating the digital literacy of museum professionals to select and utilize digital cultural heritage information is increasing. However, the current digital capacity education of museum professionals has not reached the cultivation of digital literacy due to one-way theory and one-way practical education. To overcome this, we propose a digital capacity building program using virtual museums. We propose a curriculum based on participatory museums, cooperative learning, and project-based learning theories. Learners experience the entire process of acquiring, selecting, and utilizing digital cultural heritage information through individual, cooperative, constant, exhibitions, and project-based learning programs. We were evaluated by experts in terms of education, museum education, and ICT technology education to prove its usability and derive improvements. This study will contribute to building the digital capacity of museum professionals.

Characterization of Antibiotic Resistance Determinants in Oral Biofilms

김선미,Hyeong C. Kim,이석우 한국미생물학회 2011 The journal of microbiology Vol.49 No.4

Oral biofilms contain numerous antibiotic resistance determinants that can be transferred within or outside of the oral cavity. The aim of this study was to evaluate the prevalence and the relative level of antibiotic resistance determinants from oral biofilms. Oral biofilm samples that were collected from healthy subjects and periodontitis patients were subjected to qualitative and quantitative analyses for selected antibiotic resistance determinants using PCR. The prevalence of tet(Q), tet(M), cfxA, and blaTEM was very high both in the patient and the healthy subject group, with a tendency toward higher values in the patient group,with the exception of erm(F), which was more prevalent in the healthy group. The two extended spectrum β-lactam (ESBL) resistance determinants blaSHV and blaTEM showed a dramatic difference, as blaTEM was present in all of the samples and blaSHV was not found at all. The aacA-aphD, vanA, and mecA genes were rarely detected, suggesting that they are not common in oral bacteria. A quantitative PCR analysis showed that the relative amount of resistance determinants present in oral biofilms of the patient group was much greater than that of the healthy group, exhibiting 17-, 13-, 145-, and 3-fold increases for tet(Q), tet(M),erm(F), and cfxA, respectively. The results of this study suggest that the oral antibiotic resistome is more diverse and abundant in periodontitis patients than in healthy subjects, suggesting that there is a difference in the diversity and distribution of antibiotic resistance in oral biofilms associated with health and disease.
