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 explosive growth of the internet traffic has imposed tremendous stress on routers, particularly, in the core network. Today's IP services reflect the unpredictable and undifferentiated packet loss and jitter characteristics of traditional best-effort routers. For above requirements, it is required not only the high-speed transmission of the packet, but the new routing function, the guarantees of QoS and bandwidth, the supports of user-requested services MPLS is proposed by the IETF and many other research institute as the solutions for this problem. In this paper, analyze performance of QoS Model applied RSVP over DiffServ to MPLS network. this model is each RSVP applied access network and DiffServ applied core network. In Result, It is amiss that basis MPLS net uses to core network because the average packet loss rate and average delay time are increased if traffic increases. Experiment result was seldom difference in case of network that apply each RSVP, DiffServ, RSVP over DiffServ. RSVP over DiffServs case packet loss rate and delay time were low than DiffServ and the packet loss rate is high because comparing than RSVP but delay time was very low.

The purpose of this study was to investigate the effects of the perceived relationships of the adolescents with their parent on their peer relationships. The data were collected from 385 male and female high school students in Seoul through the questionnaire method. The instruments used for this study were the Parent Bonding Instrument(PBI) and the Index of Peer Relations(IPR). The data were analyzed by the frequencies, percentiles, means, standard deviations, Cronbach α, t-tests, oneway ANOVA, Pearson`s correlations and stepwise regression, using SPSS WIN 10.0 program package. Major results of the study were as follows: 1. An analysis of data revealed that degrees the relationships of the respondents with their parents and peer were higher than moderate. 2. The adolescents` peer relationship was affected by father`s occupations, family structures, parents` marital status and the economic status of the family. 3. The stepwise regression analysis yielded the results that relationship father`s caring(β=-.364), parents` marital status(β=.150) and economic status of family(β=.130) were significant factors in explaining the adolescents` peer relationship. Based on the results of the study, needs for effective father education and enhancement of stable marital relationships were addressed.

Henoch-Schönlein purpura (HSP) is the most common form of systemic vasculitis in children. Palpable purpura, arthralgia, arthritis, abdominal pain and renal involvement are the major clinical manifestations. Gastrointestinal involvement is related with abdominal pain and bleeding. We described a 71 year-old female experienced acute exacerbation of HSP presented with gastrointestinal bleeding. She was hospitalized for hematemesis and diagnosed duodenitis by esophagogastroduonenoscopy (EGD). Duodenitis was improved at EGD checked in 7 days. She still complained of melena and abdominal pain. There were no abnormal findings at sigmoidoscopy. Jejunal ulcer and purpura were diagnosed by capsule endoscopy. Symptoms were relieved after administration of systemic steroid. But she needed renal replacement therapy for 3 months. Small bowel ulcer diagnosed by capsule endoscopy in patients with HSP was rarely described in Korean literature. This case suggests that capsule endoscopy have a role in diagnosis of small bowel ulcer and its severity in HSP with gastrointestinal symptom.

Adsorption characteristics of three endocrine disruptors, amitrol, nonylphenol, and bisphenol-A, were evaluated depending on the type and service duration of activated carbon (AC). Bituminous coal-, wood-, and coconut-based coals were tested. Bituminous coal-based AC (BCAC) had the greatest sorption capacity for the three chemicals tested, followed by wood-based AC (WAC) for nonylphenol and coconut palm-based AC (CAC) for bisphenol-A. During the column test, amitrol removal efficiency increased over time, indicating that hydrophilic endocrine disruptors are biodegraded in the AC column. Removal efficiencies of hydrophobic compounds such as nonylphenol and bisphenol-A decreased over time since the main removal mechanism was adsorption. The order of the amitrol removal was: BCAC-5.9 yr , CAC-3.1 yr > BCAC-2.2 yr > BCAC-virgin > CAC-virgin > WAC-virgin > WAC-3.1 yr. In general, used AC had greater removals than virgin AC. The order of the bisphenol-A removal was: CAC-virgin > BCAC-2.2 yr > CAC-3.1 yr > WAC-virgin > BCAC-5.9 yr > WAC-3.1 yr. The order of the nonylphenol removal was: BCAC-virgin > WAC-virgin > CAC-3.1 yr ,WAC-3.lyr> BCAC-2.2 yr > BCAC-5.9 yr > CAC-3.1 yr. Bituminous coal AC performed the best over time. Endocrine disruptors such as these three compounds appear to be removed effectively by activated carbon through biodegradation and adsorption. Wood and coal based among the virgin ACs and 3.1 years used wood base among the used ACs appeared the lowest carbon usage rate(CUR) for nonylphenol removal by prediction model. Virgin and used coconut base ACs except BCAC had the lowest CUR for removal Bisphenol-A. Biodegradation of nonylphenol and Bisphenol-A did not occurred during the 9,800 bed volume experiment period. BCAC had the highest biodegradation capacity of 46% for amitrol among virgin ACs and the used coal based ACs had 33-44% higher biodegradation capacity than virgin's for amitrol so biodegradation is the effective removal technology for hydrophilic material such as amitrol.
