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.

Objective: Ureaplasma has been demonstrated the cause of short and long-term morbidities of preterm infants, especially such as bronchopulmonary dysplasia (BPD). This study aims to evaluate the influence of Ureaplasma on neonatal morbidities and the effect of macrolide treatment in very low birth weight (VLBW) infants. Methods: We performed a retrospective review of clinical records of VLBW infants born between 2015 and 2016. Their endotracheal aspirate and gastric juice were obtained immediately after birth and tested for Ureaplasma. Therapeutic macrolides were administered according to the clinical judgment, not routinely, in Ureaplasma-positive infants. Neonatal morbidities were compared using individual matching analysis between Ureaplasma-positive and negative groups, and with macrolides administration. Results: A total of 144 infants with the mean (±standard deviation) gestational age of 28<sup>+3</sup> (±3<sup>+3</sup>) weeks and birth weight of 1,051.9 (±290.0) g were included, and 30 (20.8%) were Ureaplasma-positive. Ureaplasma-positive group was associated with higher incidence of respiratory distress syndrome (RDS, P=0.039) and severe neurologic injury (SNI; intraventricular hemorrhage ≥grade 3 or periventricular leukomalacia, P=0.013). However, Ureaplasma-positive group was not associated with the risk of BPD (P=0.706). In the subgroup analysis for Ureaplasma-positive infants, there was no difference in the incidence of morbidities according to the macrolides administration. Conclusion: Although Ureaplasma has no independent role in the development of BPD, Ureaplasma- positive VLBW infants were more likely to have RDS and SNI. The macrolides administered in Ureaplasma-positive was not effective to reduce neonatal morbidities.

<P><B>Abstract</B></P> <P>Nonimmune hydrops fetalis is the most severe clinical manifestation of lysosomal storage diseases (LSDs). Around 14 different LSDs have been accounted for as 1–15% of the cause of nonimmune hydrops fetalis. We report a Korean infant affected by an extremely rare but severe form of sialic acid storage disease. The patient presented with nonimmune hydrops fetalis, dysmorphic facial features, hepatosplenomegaly, and dysostosis multiplex and died at 39 days of age due to persistent pulmonary hypertension. LSD was suspected based on the presence of diffuse vacuolation of syncytiotrophoblast, villous stromal cells, and intermediate trophoblast in placental biopsy. Increased excretion of urinary free sialic acid was detected by liquid chromatography-tandem mass spectrometry. The patient was compound heterozygous of the c.908G>A (p.Trp303Ter) and the splicing mutation c.1259+5G>T (IVS9+5 G>T) in the <I>SLC17A5</I> gene.</P>

Background: Human breast milk is essential and provides irreplaceable nutrients for early humans. However, breastfeeding is not easy for various reasons in medical institution environments. Therefore, in order to improve the breastfeeding environment, we investigated the difficult reality of breastfeeding through questionnaire responses from medical institution workers. Methods: A survey was conducted among 179 medical institution workers with experience in childbirth within the last five years. The survey results of 175 people were analyzed, with incoherent answers excluded. Results: Of the 175 people surveyed, a total of 108 people (61.7%) worked during the day, and 33 people (18.9%) worked in three shifts. Among 133 mothers who stayed with their babies in the same nursing room, 111 (93.3%) kept breastfeeding for more than a month, but among those who stayed apart, only 10 (71.4%) continued breastfeeding for more than a month (P = 0.024). Ninety-five (88.0%) of daytime workers, 32 (94.1%) two-shift workers, and 33 (100%) three-shift workers continued breastfeeding for more than a month (P = 0.026). Workers in general hospitals tended to breastfeed for significantly longer than those that worked in tertiary hospitals (P = 0.003). A difference was also noted between occupation categories (P = 0.019), but a more significant difference was found in the comparison between nurses and doctors (P = 0.012). Longer breastfeeding periods were noted when mothers worked three shifts (P = 0.037). Depending on the period planned for breastfeeding prior to childbirth, the actual breastfeeding maintenance period after birth showed a significant difference (P = 0.002). Of 112 mothers who responded to the question regarding difficulties in breastfeeding after returning to work, 87 (77.7%) mentioned a lack of time caused by being busy at work, 82 (73.2%) mentioned the need for places and appropriate circumstances. Conclusion: In medical institutions, it is recommended that environmental improvements in medical institutions, the implementation of supporting policies, and the provision of specialized education on breastfeeding are necessary to promote breastfeeding.
Balancing energy use against video quality in mobile devices

<P>It is now common to access mobile video services through various Internet-connectable devices such as game stations, smartphones and tablets. This paper proposes a new energy management scheme for mobile devices by making use of the temporal scalability available in scalable video coding (SVC) techniques. The proposed scheme determines a quality index for each video segment, based on the pixel-wise difference between the luminance planes of consecutive frames at each frame-rate, and predicts the computation needed to decode each frame using data relating frame sizes to previous decoding times. A new dynamic voltage and frequency scaling (DVFS) scheme is then invoked to achieve the specified quality index. The proposed scheme was implemented on a smartphone and a user test was conducted to assess the acceptability of different degree of frame-rate reduction. Real measurements showed that the proposed scheme uses between 5% and 41% less energy than the Linux DVFS governor used in many smartphones, while maintaining acceptable video quality.</P>
