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.

Background: Woori-Heukdon (KWH) is a Korean synthetic pig breed generated using Chookjin-Duroc (KCD), Chookjin-Chamdon (KCC), and their crossbreds. Currently, there is a severe lack of studies investigating the Korean breed populations including wild boars (KWB) throughout the genome. Objective: This study was performed to investigate the genetic characteristics of Korean pig populations at the genome-wide level. Methods: Using the SNP dataset derived from genotyped and downloaded datasets using the Illumina PorcineSNP60K BeadChip, we compared the genomes of 532 individuals derived from 23 pig breeds to assess the genetic diversity, inbreeding coefficient, genetic differentiation, and population structure. Results: KWB showed the lowest average expected heterozygosity (HE = 0.1904), while KWH showed the highest genetic diversity (HE = 0.02859) among Korean populations. We verified that the genetic composition of KWH, showing USD of 74.8% and KCC of 25.2% in ADMIXTURE analysis. In population structure analyses, KCC was consistently shown to be separated from other pig populations. In addition, we observed gene flow from Western pigs to a part of Chinese populations. Conclusion: This study showed that Korean native pigs, KCC have genetic differences in comparison with Chinese and Western pigs; despite some historical records and recent genetic studies, we could not find any clear evidence that KCC was significantly influenced by Chinese or Western breeds in this study. We also verified the theoretical genomic composition of KWH at the molecular level in structure analyses. To our knowledge, this is the first genomic study to investigate the genomic characteristics of KWH and KCC.

대동맥 판막 치환술 후 반복되는 Acinetobacter baumannii 균혈증의 원인이 된 대동맥염 1예

감염성 대동맥염은 흔하지 않지만 매우 위중한 질병으로 Salmonella so.와 S. aureus가 주된 원인균이다. 아직까지 병원내 감염의 주요 원인균인 Acinetobacter baumannii에 의한 감염성 대동맥염은 보고된 바가 없었다. 저자들은 대동맥 판막 치환술을 시행받은 76세 남자 환자에서 적절한 항생제 투여에도 반복되는 A. baumannii 균혈증의 원인이 감염성 대동맥염으로 진단되었던 1예를 경험하였기에 보고하는 바이다. Infectious aortitis is an uncommon yet, life threatening disease. Early surgical treatment and prolonged antibiotic therapy is crucial to survival. Salmonella sp. and Staphylococcus aureus are the most common organisms isolated. There is no case report of infectious aortitis caused by Acinetobacter baumannii, which has recently emerged as a major cause of health care-associated infections. Here, we describe a 76-year-old male with infectious aortitis who experienced recurrent bacteremia due to A. baumannii in spite of adequate antimicrobial therapy after aortic valve replacement.

저자들은 호흡곤란, 흉부불쾌감, 심계항진 등을 주소로 내원한 환자에서 경흉부 및 경식도 심초음파 검사상 주폐동맥에서 이완기에 전행하는 지속적인 혈류의 흐름을 관찰하고, 관상동맥 조영술을 통해 좌전하행지 중간부위와 우관상동맥 근위부에서 각각 기시하여 공통경로를 이루면서 주폐동맥으로 유입되는 양측성 관상동정맥루를 보이는 드문 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. A coronary arteriovenous fistula is infrequently encountered vascular communication between a coronary artery and a cardiac chamber, a great artery or the vena cava. It is the most common congenital anomaly that can affect coronary perfusion. Bilateral involvement of coronary fistula constitutes an uncommon subgroup of coronary arteriovenous fistulas. A 69 year-old female patient presented with chest discomfort, palpitation, and dyspnea. In the echocardiography, doppler color flow imaging visualized abnormal flow signals with mosaic appearance in the main pulmonary artery during diastolic phase. Coronary angiography revealed arteriovenous fistula arising from the left anterior descending artery and the right coronary artery. Both coronary arteriovenous fistulas drained into the main pulmonary artery. We report a case of bilateral coronary arteriovenous fistula that was confirmed by echocariography and coronary angiography.

2004년 7월 봇돌바다의 영양염과 Chlorophyll-a의 단기 변동

In order to study the temporal variations of nutrients and chlorophyll-a in the Bottol Bada, three field observations were carried out on 20, 23 and 26 July, 2004. The low N:P values exhibit nitrogen deficiency during the periods of observation. This result is not representative of typical summer environment in the southern coast of Korea. The possible mechanisms are as follows: 1) The freshwater inflow was not sufficient for the supply of nitrogen because the total precipitation was 11.9 mm in July, 2004. This amount is no more than 5% in normal precipitation in July. 2) There was an inflow of oceanic water under the subsurface into the Bottol Bada. Even though the oceanic water comprises more nutrients, it produces the stratification between the surface and the subsurface water and seems to prevent the supply of nutrinets to the surface layer. 3) The high chlorophyll-a concentration of 1.2 ㎍/L was shown near the narrow channel between Gae-do and Geumo-do. This seems to be resulted from the inflow of water from Gamak Bay.

2004년 7월 봇돌바다의 썰물, 전류 및 밀물시 수온과 염분 분포

Based on the observation on 20, 23 and 26 July 2004, the distributions of temperature, salinity and stratification was investigated in relation to ebb, turn of tide and flood. The results are as follows: 1) The high temperature and low saline water with 23.5-24.0℃ and 32.4~33.0psu existed at Naro Island. 2) The cold surface water below 21.00 and 33.0~33.4psu appeared in the area near Gae Island and Geumo Island. 3) The cold and saline water, below 24.0℃ at the surface and 17.0℃ near the bottom, 32.8~33.8psu at the surface and 33.8~34.0psu near the bottom, existed in Sori Island. These waters were more saline compared to the South Sea Coastal Water with about 31.8psu. This suggests that the oceanic saline water intruded into the Bottol Bada through the area near Sori Island. The stratification appeared during all the observation periods due to a high solar radiation of 22MJ/m², and a weak wind speed of 2.9m/s on the average while the mean speed of wind in July is around 3.9 m/s. It qualitatively suggested that the stratification was maintained during the observation periods because of a high solar radiation, a weak wind speed and intrusion of saline oceanic water.

Hot-wall epitaxy에 의하여 GaAs (100) 기판 위에 성장된 ZnS_1-xTe_x(0<x<1) 단결정 박막의 특성이 Raman 산란을 이용하여 조사되었다. Raman 산란으로부터 측정된 장파장의 ZnTe-like의 longitudinal 광학 포논의 주파수는 성분비 x와 함께 선형으로 변하였다. ZnS_1-xTe_x 단결정 박막의 x의 함수로서 zone-center 광학 포논의 주파수는 two-mode이었고, 이 결과는 MERI 모델의 이론치와 잘 일치하였다. ZnS_1-xTe_x(0<x<1) alloys grown on (100) GaAs substrates by hot-wall epitaxy are investigated using Raman scattering. The frequencies of long wavelength ZnTe-like and ZnTe-like longitudinal optical phonons determined from Raman scattering show linear variation with the composition x. The frequency of the zone-center optical phonons as a function of x of the ZnS_1-xTe_x mixed crystal shows a typical two-mode behavior. which is in good agreement with the theoretical results from a modified random-element isodisplacement model.

김석용, 이상진, 최재운, 김승렬, 김용대, 배성은, 김영규 충북대학교 의과대학 충북대학교 의학연구소 2012 忠北醫大學術誌 Vol.22 No.1

연구목적: 팀티칭에 근거한 통합강의는 최근 대부분의 의과대학에서 시행되는 강의형태이다. 그러나 기 존에 사용되고 있는 온라인 강의평가 방식은 이러한 강의 특성에서 나타나는 문제점을 파악하기 힘든 점이 있다. 본 대학에서는 팀티칭에 의한 통합강의에서 문제강의를 직접적으로 파악하는 ‘문제강의 직 접평가지’를 개발하였다. 본 연구의 목적은 새로이 개발된 문제강의 직접평가지가 강의개선에 끼친 영 향력을 알아보고자 하는 것이었다. 연구방법: 2007년 2학기부터 2009년 2학기까지 충북대학교 의과대학 1, 2학년을 대상으로 문제강의 직접평가지에 의한 강의평가를 실시하였다. 평가지 질문 중에서 두 가지 객관식 질문에 대한 답변을 분 석대상으로 선택하였다. 질문은 첫째, ‘가장 유익하고 도움이 많이 되었던 강의들은 무엇입니까?’와 둘 째, ‘가장 어렵거나 이해하기 힘들었던 강의들은 무엇입니까?’였다. 강의평가를 실시한 강좌들 중에서 2 년 이상 연속적으로 강좌구조와 평가지의 객관식 질문 형식이 변하지 않은 14개의 강좌를 분석대상으로 하였다. 각각 연도의 평균 긍정비율을 다른 연도의 것과 카이제곱 검정 방법을 사용하여 비교하였다. 결과: 14개의 강좌 중에서 시작연도와 마침 연도 간에 긍정비율이 증가된 경우는 13개 강좌였다. 그 러나 통계적으로 의미가 있는 경우는 5개 강좌에서 나타났다. 결론: 문제강의 직접평가지에 의한 문제강의를 판별해 내는 방법은 단기간에 통합강좌의 개선에 효과 적이다.
