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 : Many students major in applied music singing have various difficulties in phonation when they sing or perform. But the studies about this cause are lack. The purpose of this study is whether singing voice therapy based on vocal music is effective or not to applied music singing students that have difficulties in phonation. Materials and Methods : Singing voice therapy program had been done to 8 students major in applied music singing during 7 weeks. We did laryngeal stroboscope, perceptual, acoustic and aerodynamic examination before and after singing voice therapy to this students. And we studied post examination results have differences or improvements compared to pre examination results. Results : Four male students don't have effective improvement after singing voice therapy but they shows slight improvement in aerodynamic examination values compared to pre examination values. Four female students shows improvement in aerodynamic examination values and pitch range increasing. Above all, one student's vocal nodules disappeared after singing voice therapy. Conclusion : Singing voice therapy based on music singing is very effective to the students major in applied music singing. Above all, their curriculum in applied music singing should include phonation training based on music singing before training perform and technic practices.

한국 Drosophila immigrans 집단의 유전적 구조를 밝히는 연구의 일환으로 5개집단(설악, 대전, 광주, 부산, 제주)을 대상으로 pair-mating시켜 "dissection of sperm"방법을 이용하여 동소집단과 이소집단의 성적격리를 실험하였다. 본 실험의 결과는 다음과 같다. (1) 한국 D. immigrans 집단의 경우 동소집단의 성적격리도가 이소집단보다 높았으며 Ehrman & Parsons^17,18)과는 상반되는 결과를 보였다. (2) 지리적격리가 성적도태 요인이 되지 않는 것 같다. (3) 한국 D. immigrans 집단의 평균성적격리도는 지금까지 조사된 어느 집단보다도 낮았다. (4) 집단간의 성적격리도는 통계적으로 유의한 차를 보였다. (5) 한국 D. immigrans 집단의 성적격리는 "founder effect"로 설며하는 것이 타당하나, 환경여건 및 "habitat selection"에 의해 일어나는 현상도 결코 배제할 수 없을 것 같다. (6) isofemale 계통에 관한 계속적인 연구가 행하여지는 경우, 한국 D. immigrans 집단의 성적격리에 의한 진화문제에 좋은 자료가 될 것으로 기대한다. In order to clarify the genetic structure of Korean populations of Drosophila immigrans, the natural populations of D. immigrans were sampled at 5 localities (Mt. Sorak, Daejon, Kwangju, Pusan, Jeju isl.). By pair-mating and dissection of sperm, sexual isolation in sympatric and allopatric populations was analyzed. The results are as follows: 1. Sexual isolation of sympatric populations is higher than that of allopatric populations and it is opposed to the results of Ehrman and Parsons.^17,18) 2. The degree of isolation does not depend upon the geographic distance. 3. It was noted that the average isolation indices observed in Korean populations of D. immigrans were low as compared with those of several populations of D. immigrans by other workers. 4. Statistically significant sexual isolation occured between populations. 5. It is suggested that the maintenance of sexual isolation in Korean populations of D. immigrans be due to "founder effect" and cannot be excluded that it is due to environmental conditions and "habitat selection". 6. The detailed study of isofemale strains will give an idea of the potential for evolution of sexual isolation in Korean populations of D. immigrans.

This experiments were performed using O₃, ClO₂and Granular activated carbon in order to remove 2-MIB(2-Methylisobornelo) causig odor in water. In Freundlich equilibrium experiments, 2-MIB was well adsorbed in PAC comparatively and raw water containing TOC was less adsorbed than distilled water by effect of TOC. Jar tests with coconut-based PAC were showed high removal efficiency of 2-MIB in proportion to contact time and concentration of PAC. Oxidation capacity of O₃was demonstrated to be superior to that of ClO₂. Prepared comparatively highly initial concentration as 1991ppt of raw water was treated with post-O₃in condition of 1ppm and 12min. of contact time and then its residual concentration was approximately 569ppt(70% removal efficiency), and the 2-MIB removal efficiencies of the Post-O₃water through coal, coconut shell, wood and zeocarbon based GAC(granular activated carbon) column were 95.8%, 89.5%, 88.4% and 93.7%, respectively. Coal based carbon have most effective adsorption capacity but wood based carbon have a little lower adsorption capacity than others. In GAC column experiment, TOC, UV-254, 2-MIB and so on ewere removed most effectively in case of A(coal) and for this experiment intervals, the change of water quality(UV-254, TOC) was not happened by input of odor substance(2-MIB).
