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.

Scrub typhus usually occurs in October and November in Korea. Its typical clinical manifestations are fever, rash, eschar, and lymphadenopathies. Pneumonitis may occur, however it occurs as a complication at the late phase of scrub typhus, when it is inappropriately treated. We encountered a case of pneumonitis that was an initial manifestation of scrub typhus which was confirmed by rickettsial culture, Positive seroconversion, and polymerase chain reaction. The case was a 16-year-old high school adolescent who presented with fever and headache that lasted for 1 day in July, 2007, He denied of any outdoor activities. A chest radiograph showed patchy infiltrates in the left lower lung, which improved with the administration of cefotaxime and azithromycin for empirical treatment of community-acquired pneumonia. Blood taken on the second febrile day showed a positive culture for Orientia tsutsugamushi and was also positive for O. tsutsugamushi DNA polymerase chain reaction. Immunofluorescent antibody (IFA) test for O. tsutsugamushi showed that the initial antibody was negative, but convalescent serum tested positive with an antibody titer of 1:80. IFA for Coxiella burnetii showed false positive results; the initial IgM and IgG liters were 1:128 and 1:256, respectively, and the IgM and IgG titers in convalescent serum were 1:128 and 1:128, respectively.

This research was carried out to enhance the removal efficiencies of COD_Cr and color from dyeing wastewater by Fenton process, involving oxidation and coagulation. The experimental variables for this study include dosage division ratio of hydrogen peroxide and amount of Fenton's reagent. In the case of H_2O_2 divided dosage, 7:3 was more effective than 3:7 to remove COD_Cr and color. The results show than COD was mainly removed by Fenton coagulation, where the ferric ions are formed in the initial Fenton reaction. In contrast, color was removed by Fenton oxidation rather than Fenton coagulation. It was found out that overdose of Fenton's reagent has been applied in the "B" Treatment Plant. In spite of 20% reduction of the hydrogen peroxide dosage, effluents are satisfied with Discharged Water Quality Standards.

Objectives: To investigate whether polymorphism of gene encoding estrogen receptor-a is asso-ciated with the risk of endometriosis in Korean women. Material and Methods :We investigated 136 patients with histopathologically confirmed endo-metriosis rAFS stage III/IV and 251 control group women who were surgically proven to have no endometriosis. Polymerase chain reaction(PCR) and restriction fragment length polymorphism (RFLP) of PCR products were done to determine each participant's estrogen receptor-a genotype. Results : The distridution according to PvuII genetic polymorphism of estrogen receptor-a were as follows. PP, Pp and pp were 14.7%(20 women), 39.0%(53 women) and 46.3%(63 women) in the study group and 13.9%(35 women), 38.6%(98 women) and 47.4%(119 women) in the con-trol group, respectively. There was no significant difference between the study group and the control group. Conclusion : The results suggest that estrogen receptor-a genetic polymorphism may not be associated with the development of endometriosis in Korean women. 목적: 자궁내막증은 에스트로겐에 의존적인 질환이므로 에스트로겐의 합성, 대사 및 작용에 관여하는 유전자의 다형성이 자궁내막증의 발생기전에 중요한 역할을 할 수 있다. 이에 본 연구에서는 한국인 여성에서 에스트로겐 수용체-a의 유전자 다형성이 자궁내막증의 발생 위험도를 증가시키는 지에 대해 연구하고자 하였다. 방법: 1996년 9월부터 2003년 8월가지 본원 산부인과에서 수술을 통해 병리조직학적으로 자궁내막증 III기와 IV기를 확인한 한국인 여성 136명을 대상으로 하였다. 대조군은 자궁내막증 환자군과 연령이 비슷한 만삭 산모에서 제왕절개술을 시행하거나 양성 난소낭종으로 수술을 시행 하였을 때, 자궁내막증이 없음을 확인한 여성 251명 으로 하였다. 결과: ER-a 유전자의 PvuII 다형성의 분포는 자궁내막증 환자군에서 PP군이 20명(14.7%), Pp군이 53명(39.0%), pp군이 63명(46.3%) 이었고 대조군에서의 분포는 각각 35명(13.9%), 97명(38.7%), 119명(47.4%)으로 나타났으며 자궁내막증 환자군과 대조군 사이의 유의한 차이는 없었다. Pp, pp형을 가지는 경우가 자궁 내막증 환자의 85.3%(116명), 대조군의 86.1%(216명)로 나타났으며, 이 경우 자궁내막증이 발생할 odds ratio가 0.904(95% CI, 0.519~1.702)로 통계적으로 유의한 차이가 없었다. 결론: 이상의 결과로 볼 때, 한국인 여성에서 자궁내막증의 발생위험과 에스트로겐 수용체 a 유전자 다형성간에 연관성은 없는 것으로 나타났다.

The purpose of this study is to analyze synoptically some characteristics of the surface inversion at Kori, southeastern part of Korea and to be useful for a searching examination of the air pollution potenial at a coastal industrial region. The data used in this study are the temperatures at 20m and 1.5m above the surface, wind velocity and wind direction observed hourly at the monitoring station which is located at Gilcheon-ri (N35˚19'44", E129˚17'20") near Kori in Korea, from December, 1967 to November, 1970. By analyzing these data statistically and synoptically, the following results were acquired. 1) The occurence frequency of the surface inversion is the highest in November and the lowest in June. In seasonal variation, autumn has the highest and summer has the lowest occurrence frequency. 2) The modes of the onset and dispersion times of the surface inversion are 18:00 and 08:00 respectively. The annual mean duration of the surface inversion is 11.3 hours. 3) The aspects of annual variations of inversion intensity and occurrence frequency with time are similar to each other and also have a close connection with sunrise, sunset and the changing time of land and sea breezes. 4) According to Pasquill's stabillity classification in inversion cases, it was proved that there are the classes of E, F and G being stable in inversion cases at Kori.
