Purpose: Pediatricians have a significant responsibility to educate mothers about the importance of breastfeeding. However, there have been minimal efforts in the courses of resident training in Korea. The purpose of this study is to evaluate the change in knowledge and attitude before and after a 4-week breastfeeding educational intervention among multicenter residents. Methods: Prospective interventional educational research was designed for residents at eight training hospitals in Korea. Institutional reviews were obtained in each hospital. The education curriculum consisted of 14 courses regarding breastfeeding theory and practice. These materials were used to teach pediatric residents for 4 weeks. Knowledge-based tests were administered before the course, and re-tests were administered after the course using different test items of similar levels. Test scores and survey responses were compared before and after the intervention. Results: A total of 73 residents (1st year 20, 2nd year 23, 3rd year 16, and 4th year residents 14) from eight training hospitals completed the intervention. Their average age was 30.3±2.9 years, 17 (23.3%) were male, 22 (30.1%) were married, and eight had more than one child of their own. The mean pre-test score was 61.8±13.4 and the mean post-test score was 78.3±7.5 (P<0.001). The inter-grade difference in the score was significant in the pre-test (P=0.005), but not significant in the post-test (P=0.155). There were more responses of obtaining confidence after the intervention (P<0.001). Conclusion: In our study, pediatric residents showed improvement in their knowledge and confidence level after 4 weeks of the breastfeeding curriculum. This will provide a basis for future policymaking in the training of pediatric residents regarding breastfeedReceived: 6 January 2022 Revised: 15 February 2022 Accepted: 15 February 2022 Correspondence to: Ellen Ai-Rhan Kim, MD Department of Pediatrics, Asan Medical Center, University of Ulsan College of Medicine, 88 Olympic-ro 43-gil, Songpa-gu, Seoul 05505, Korea Tel: +82-2-3010-3390 Fax: +82-2-3010-6978 E-mail: arkim@amc.seoul.kr A Multi-Center Educational Research Regarding Breastfeeding for Pediatrics Residents in Korea Yong-Sung Choi, MD,PhD1, Sung-Hoon Chung, MD, PhD2, Eun Sun Kim, MD, PhD3, Eun Hee Lee, MD4, Euiseok Jung, MD5, So Yeon Lee, MD, PhD5, Wooryoung Lee, MD6, Hye Sun Yoon, MD, PhD7, Yong Joo Kim, MD, PhD8, Ji Kyoung Park, MD, PhD9, Son Moon Shin, MD, PhD9, and Ellen Ai-Rhan Kim, MD, PhD5 1Department of Pediatrics, Kyung Hee University Hospital, Seoul, Korea 2Department of Pediatrics, Kyung Hee University Hospital at Gangdong, Seoul, Korea 3Department of Pediatrics, Kangwon National University Hospital, Chuncheon, Korea 4Department of Pediatrics, Korea University Anam Hospital, Seoul, Korea 5Department of Pediatrics, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea 6Department of Pediatrics, Soonchunhyang University Seoul Hospital, Seoul, Korea 7Department of Pediatrics, Nowon Eulji Medical Center, Eulji University, Seoul, Korea 8Department of Pediatrics, Hanyang University Seoul Hospital, Seoul, Korea 9Department of Pediatrics, Inje University Busan Paik Hospital, Busan, Korea Neonatal Med 2022 February;29(1):28-35 https://doi.org/10.5385/nm.2022.29.1.28 pISSN 2287-9412 . eISSN 2287-9803 Copyright(c) 2022 By Korean Society of Neonatology This is an Open-Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http:// creativecommons.org/licenses/by-nc/4.0), which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

주우철,최용준,박재은,이혜명,이진수,정문현,김수미,문지혜 대한감염학회 2008 감염과 화학요법 Vol.40 No.4

HHV-8 virus is known to be associated with Kaposi's sarcoma (KS) in HIV seropositive patients and its seroprevalence has geographic difference, In South Korea, incidence of KS is low not only in general population but also in HIV patients compared to other countries, It is speculated that low seroprevalence of HHV-8 has contributed to the low incidence of KS in South Korea. We examined the seroprevalence of anti HHV-8 IgG of HIV seronegative health care workers in one University hospital. Enzyme-linked immunosorbent assay(ELISA) was used for diagnosis. One person (0.6% 1/164) was seropositive, six were equivocal (3.7%,6/164) and 157 people were seronegative (95.73%, 157/164). This study revealed that seroprevalence of HHV-8 in general population was. low in South Korea. Further studies are needed to be carried out to evaluate the low HHV-8 seroprevalence in Korea.

구강 내 디지털 인상채득을 통한 맞춤형 지대주와 시멘트 합착 후 나사형 임플란트 보철 수복 증례

홍용신,박은진,김선종,김명래,허성주,박지만 대한치과보철학회 2012 대한치과보철학회지 Vol.50 No.1

최근 디지털 인상채득 시스템이 개발되면서 이를 기존의 CAD/CAM 시스템과 접목한 인레이, 온레이, 크라운이나 간단한 계속가공의치 등의 고정성 보철물의 제작이 활발히 소개되고 있다. 그러나 임플란트 보철에서는 주로 기존의 아날로그식 인상채득 후 이를 스캔하여 제작하는 방법이 사용되어 왔으나, 구강 내 디지털 스캔한 데이터를 이용하여 나사형 보철물을 제작하는 술식은 아직 활발히 이루어지지 않았다. 이에 본 증례보고에서는 6명의 환자를 대상으로 구강 내 스캐너인 iTero를 사용하여 디지털 스캔을 시행한 후 그중 다섯명은 맞춤형 지대주와 시멘트 합착 후 나사형 임플란트 보철물(screw-retained implant prosthesis after cementation, or SCRP)을 제작하였고, 임상적으로 기능과 심미적인 측면으로 만족할 만한 결과를 얻었기에 이를 보고하고자 한다. Fixed dental prostheses such as inlay, onlay, crown, and bridge fabricated by CAD/CAM technique combined with digital impressions is getting popular due to the recent rapid progress of digital impression taking system. For the scope of implant prosthesis, however, digital intra-oral scan hasn’t been actively utilized for the fabrication of superstructures. In this case report, 6 cases of titanium-milled custom abutment based on the iTero intra-oral scan data were introduced, five of them were restored with screw-type prosthesis after cementation (SCRP) and the clinical results were satisfactory on restoring the function and esthetics.

홍용신,박은진,김성균,곽재영,허성주,박지만 大韓齒科保存學會 2011 Restorative Dentistry & Endodontics Vol.36 No.6

구강 스캐너와 CAD/CAM 기술로 인해 컴퓨터로 제작하는 방식이 활발히 보급된 고정식 보철 증례와는 달리, 의치를 디지털 방식으로 제작하는 데에는 아직 한계가 많다. 촉각을 느낄 수 있는 입력 장비와 전자 서베잉의 개념, 그리고 쾌속 조형법의 적용으로 인해 국소의치를 디지털로 제작할 수 있는 솔루션이 최근 소개되고 있다. 본 증례보고에서는 이러한 국소의치의 디지털 솔루션을 이용하여 총 다섯 명의 환자에서 서베이드 금관 및 국소의치를 제작하였다. 인상 과정상의 문제로 모형과 실제 치아 사이의 형태적 차이가 있었던 경우를 제외하고는 국소의치의 적합도는 우수했으며, 장착 후 안정성과 착탈 시의 유지력 또한 임상에서 적용하는 데에 문제가 없었다. There are still many limitations on fabricating dentures using digital method while computerized production of fixed prostheses utilizing intraoral scanner and CAD/CAM technology has propagated rapidly. Recently the digital solution of fabricating removable partial denture by applying haptic input device, electronic surveying, and rapid prototyping was introduced. In this case presentation, five patients were treated with surveyed crown and removable partial dentures by this digital solution. Fit of dentures was excellent except for one case which showed morphological difference between the actual teeth and that of master cast by the erroneous impression process. There also was not any problem of stability and retention after adaptation in the clinical setting.

이지수,이성우,박주용,김준연,심재우 한국공업화학회 2004 응용화학 Vol.8 No.2

The important parameters that have significant effects on the prediction of CHF (Critical Heat Flux) for R-12 (Dichlorodifluoromethane) were investigated. This was a preliminary study for a R-12 CHF correlation in uniformly heated vertical round tubes. Experimental data of Celata [1], Green and Stevens [2], Groenveld [3], Ilic [4], Katto [5], Merilo and Ahmad [6] and Stevens and Miles [7] were used for this analysis. Four representative CHF data sets at pressure condition of 9, 15, 19, and 27 bar were selected, analyzed, and compared to evaluate the effects other than the system pressure on the CHF were tube diameter (D), mass flux of water (G), and local true mass fraction of vapor (X_(t)). The results of this study have reaffirmed the feasibility that an advanced R-12 CHF correlation for uniformly heated vertical round tubes can be found.

김지민,박주용,이지수,이성우,심재우 한국공업화학회 2003 응용화학 Vol.7 No.1

Three representative models for the reediction of true mass fraction of steam were compared and analyzed to determine most appropriate model that can used to predict the Critical Heat Flux (CHF) for flow of wate in uniformly heated vertical tubes, The models studied were Kroeger & Zuber's [1]. Levy's[2] and Jafri et al.'s[3]. for the comparison. 188 data points from Becker et al.[4] (10 MP a data) were selected as a representative sample from the CHF database that contains a total of 8.912 data points. In case of Kroeger & Zuber vs. Jafri et al., the average error was 0.33% and the root mean square error was 2.47%. In case of Levy vs. Jafri et al., the average and root mean square errors were 1.66%, 2.67% respectively. Jafri et al.'s model can be applied to both uniform and non-uniform heated tubes because it is in a from of rate equation that can easily be used for calculating the true fraction of steam along the length of tube.

백혈병환자에서 Liposomal Amphotericin B로 치료된 파종성 Fusarium 감염 1예

이지연,김성범,박대원,신성희,김용현,윤소영,엄중식,최철원,정희진,김우주,김준석,김장수,이갑노 대한감염학회 2003 감염과 화학요법 Vol.35 No.5

Fusarium spp.는 사람에서 드물게 각막염, 조갑진균증, 상처나 화상부위감염 등을 유발하는 것으로 알려져 있으나 최근에는 면역저하자에서 기회감염의 원인균으로 증가하고 있는 추세이다. 면역저하자에서 파종성 감염이 있는 경우에 예후는 치명적이나, 증례가 많지 않고 진단방법이 제한되어 있어 조기 진단과 신속한 치료가 쉽지 않다. 그러나 특징적으로 피부병변의 동반이 흔하여 면역저하자에서는 피부 병변의 면밀한 관찰과 함께 Fusarium 감염을 조기에 의심하여 피부생검이나 배양을 하는 것이 진단에 도움이 되리라 생각된다. 파종성 Fusarium 감염의 치료로는 감염 부위의 국소적 외과적 절제와 전신적 항진균제의 사용이 필요하고 현재까지는 amphotericin B가 비교적 효율적인 항진균제로 알려져 있으나 면역저하자에서 이에 반응을 하지 않는 경우가 많다. 저자들은 급성골수성백혈병 환자에서 관해유도화학요법 시행 후 호중구감소상태에서 피부병변과 폐침윤이 발견되었고 피부의 중심부 궤양을 동반한 구진성 병변에서 배양검사를 통해 파종성 Fusarium 감염을 진단하였으며 liposomal amphotericin B (AmBisome )를 사용하여 성공적으로 치료한 예를 경험하여 보고하는 바이다. Fusarium spp., basically a superficial pathogen, is a newly emerging fungal pathogen of opportunistic infections in immunocompromised patients. At present, although Fusarium spp. are relatively resistant to amphotericin B, the combination of amphotericin B and surgical debridement appear to be optimal treatment for disseminated infection. Recently we experienced a 32-year-old neutropenic patient after induction chemotherapy for acute myelocytic leukemia presented with skin lesions and infiltrations in both lungs. We diagnosed with disseminated fusariosis by skin culture and successfully treated the patient with liposomal amphotericin B. We emphasize a high index of suspicion for skin lesions especially in immunocopromised patients.
