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.

The purpose of this study was to investigate the relation between the traditional sense of values of mothers and personality of children on the hypothesis of that the former would influence the later. The detail Purposes of this study are: 1. Does the traditional sense of values of mothers differs in terms of some selected variables(age, education, income, residence, family structure)? 2. What relation does the traditional sense of values of mothers have with the personality of children(female or male)? 3. How do the relations between the traditional sense of values of mothers and the personality of children differ in terms of family structure(extended or nuclear family)? The subjects for this study were students and their mothers of 3 elementary schools located in Seoul(the detail location of the schools are in Kang-Nam Gu, in Kang-Buk Gu, and in Kang-Dong Gu) and 1 elementary school located in Yeosu. The research data in this study was collected from 187 children(and their mother) in Seoul and 199 children(and their mother) in Yeosu. This study used value-oriented scale made by Lim, Hee-seop(1994) to measure the traditional sense of values of mothers, and personality test for elementary school made by Jung, Beom-mo to measure personality of children. The data was processed and analysed through the statistical methods(SAS computer program), t-test, on-way Anova, and Multiple Regression(Stepwise). The major findings of this study are as follows. First, in the research to find out the difference of the traditional sense of values in terms of family conditions, authoritarianism had significant difference when residence, father's age. Mother's education level change. In other words, the authoritarianism was stronger the more the father was old, the less the mother was educated. And the authoritarianism was stronger in the country. Familism had significant difference when residence, education level of stronger the less the mother and father were educated, the less the income was. And the authoritarianism was stronger in the country. Humanism had significant difference when education level of mothers, income level changed. In other words, humanism was stronger the more the mother was educated, the more the income was. Second, in the research to find out the traditional sense of values of mother which explains the personality of children best in terms of sex of the children, the familism explains the reflectiveness of male children best, and the humanism explained the emotional stability of male children best. And for the female children, the authoritarianism of mother was found out to be the most provable explanative variables which explained the impulsiveness of female children best. Third, in the research to find out the traditional sense of values of mother which explains the personality of children best in terms of the family structure, when it was extended family the authoritarianism was found out to be the explanative variable for the impulsiveness of children. And when it was found to be the explanative variable for the impulsiveness of children. And when it was nuclear family, in the research to find out the traditional sense of values of mother which explains the personality of children best, the authoritarianism was found to be the explanative variable for the dominance and reflectiveness of children.

Tuning the Microstructure and Mechanical Properties of Cold Sprayed Equiatomic CoCrFeMnNi High-Entropy Alloy Coating Layer

Ji‑Eun Ahn,Young‑Kyun Kim,Sang‑Hoon Yoon,Kee‑Ahn Lee 대한금속·재료학회 2021 METALS AND MATERIALS International Vol.27 No.7

An equiatomic CoCrFeMnNi high entropy alloy (HEA) coating layer was prepared via a cold spray (CS) process. In orderto control the microstructure and nano-indentation properties of the CS HEA, heat treatments were employed. CS HEAcoating layer showed a heterogeneous microstructure where ultra-fine grains were formed at the particle interfaces, whilecoarse grains were formed inside the particles. Furthermore, deformation twins (DTs) were also formed inside the particlesdue to severe plastic deformation (SPD) in each particle generated during the CS deposition. For the 550 °C heat treatment(HT), fine Cr-rich precipitates were additionally formed at the grain boundary and particle boundary. By contrast, recrystallizationoccurred during 850 °C HT, while the size of the Cr-rich precipitate increased. The nano-indentation hardness ofthe CS HEA coating layer was 10.9 GPa, which was ~ 3 times higher than that of the conventional cast HEA. The superiorhardness of the CS HEA might has been enabled due to the combination of the high dislocation density, DTs, and ultra-finegrains. Based on the results above, the strategy to control the microstructure and mechanical properties through HT of theequiatomic CoCrFeMnNi HEA coating layer prepared via the CS process has been discussed.
