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 and Objectives: Lower urinary tract injuries in pelvic bone fracture can lead to significant complication. We tried to find out the relationship between the fracture location and the bladder, urethra injury in patients who sustaining pelvic bone fracture. We thought that the fracture locations could serves as markers for injury. Materials and Methods: A clinical study was made on 43 patients who sustaining pelvic bone fracture with bladder or urethra injury in the Chosun University hospital during the period of 5 years from January, 2002 to December 2006. Diagnosis was done by retrograde cystography, retrograde urethragraphy, abdomenpelvic computed tomography. Results: Of the 43 patients reviewed, 27 patients had intraperitoneal type bladder rupture, and 12 patients had extra-peritoneal type bladder rupture. 9 patients had urethral rupture. Intraperitoneal type bladder rupture cases are most commonly associated with infrapubic ramus, suprapubic ramus and acetabulum. but the statistically significance is abscent (p= 0.642). Also extraperitoneal type bladder rupture cases are most commonly associated with infrapubic ramus, suprapubic ramus and acetabulum. but the statistically significance is abscent (p= 0.548). And all type bladder rupture cases are most commonly associated with infrapubic ramus, suprapubic ramus and acetabulum. but the statistically significance is abscent (p= 0.775). And urethral rupture cases are most commonly associated with infrapubic ramus, suprapubic ramus and acetabulum but the statistically significance is abscent (p= 0.528). Lastly, Combineded bladder rupture and urethral rupture cases are most commonly associated with infrapubic ramus, llium, Symphysis pubis. But the statistically significance is abscent (p= 0.462). Conclusions: In our study when there is a pelvic bone fracture, the fractured site of pelvic bone have no statistically association with lower urinary tract injury. But most common pelvic bone fracture site of all lower urinary tract injury cases is infrapubic ramus. Therefore, if infrapubic ramus fracture is found in the condition of pelvic bone fracture, it is highly likely to have lower urinary tract injury. More careful observation and diagnosis is necessary for this case.
