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 : To report the method and efficacy of the site specific-defects repair in the endopelvic fascia and uterosacral ligament suspension for the correction of posthysterectomy vaginal vault prolapse. Methods : This study was performed in 3 patients with posthyterectomy vaginal vault prolapse who underwent the surgery for the reconstruction of endopelvic fascia and the correction of vault prolapsed vagina by using uterosacral ligament suspension at the department of Obstetrics and Gynecology in Moon-Hwa Hospital. Among them, 1 patient was treated by laparotomy, and 2 patients were treated by laparoscope. Results : The age of patients ranged from 49 to 67 years. The mean operation time was 111 minutes (105-120 minutes). The status of postoperative vagina was normal in all 3 patients, who were discharged 9 days after operation without symptoms. No complication or recurrence were found in them despite long-term follow-up for 24 months, 12 months, 7 months, respectively after operation. One patient has been treated with HRT therapy. Conclusion : The reconstruction of the defect of endopelvic fascia and uterosacral ligament fixation may be very safe, effective, and functional in the correction of vaginal vault prolapse. This study reports the treatment of vaginal vault prolapse using uterosacral ligament within Korea for the first time.

To investigate the cross contamination in the dental clinic, Staphylococcus aureus, the pathogen in acute pyogenic infection and one of the important microbes causing nosocomial infection, was isolated from the mouth and anterior nare of healthy personnel and patients and the air in the dental clinic. The patterns of antibiotic susceptibility of the isolated staphylococci were examined. The n-butanol and methanol extract of Caesalpinia sappan L. inhibited growth of the 15 MRSA isolates at the concentrations as low as 630 ㎍/㎖ and 310㎍/㎖. The antibacterial effect of volatile substances of C. boreale on the 15 MRSA isolates was shown at the concentration of 1.4 ㎕/㎖. However, the growth of 5 strains of MRSA was not inhibited at the concentration of 1.4 ㎕/㎖. The antibacterial effect of berberine on 20 strains of MRSA was shown at the concentrations less than 200 ㎍/㎖. These results suggest that staphylococci in the dental environment might be one of the important causes of nosocomial infection in the dental clinic, and the extracts of Caesalpinia sappan L., volatile substances from C. boreale and berberine might be candidate substances for antibacterial activities to the MRSA in the dental clinic.

To investigate the cross contamination in the dental clinic, Staphylococcus aureus, the pathogen in acute pyogenic infection and one of the important microbes causing nosocomial infection, was isolated from the mouth and anterior nare of healthy personnel and patients and the air in the dental clinic. The patterns of antibiotic susceptibility of the isolated staphylococci were examined. mecA gene from the MRSA was detected by polymerase chain reaction (PCR). The isolation rate of S. aureus in the dental clinic was the highest in the mouth of dentists (29.4%) and the lowest in the air of the dental clinic (1.3%). In the study of PCR, MRSA and some methicillin susceptible staphylococci had mecA positive gene. These results suggest that staphylococci in the dental environment might be one of the important causes of nosocomial infection in the dental clinic.

28세 남자가 내시경적 점막절제술을 통해 저등급 위MALT 림프종으로 진단되었다. 병기설정을 위해 18F-FDG PET 검사를 시행하였고 우측 쇄골상부, 우측상/하부 기관주위, AP window 부위에 강한 섭취가 관찰되어 전이성 림프절로 판단하였다. 그러나, 우측 쇄골상부 림프절에서 시행한 절제생검에서 만성육아종성염증소견이 관찰되었고 조직의 결핵 중합효소연쇄반응에서도 양성 반응을 보였다. 2개월간 항결핵제의 사용 후 시행한 추적 컴퓨터단층촬영 검사에서 림프절 크기의 감소를 보여 최종적으로 위 MALT 림프종에서 광범위 림프절 전이로 오인된 동시성 림프절 결핵으로 진단되었다. A 28-year-old man was diagnosed as gastric MALT lymphoma in diagnostic EMR (endoscopic mucosal resection). He subsequently underwent an 18F-FDG PET. 18F-FDG PET showed intense multifocal uptake in right supraclavicular, right upper and lower paratracheal, and AP window areas that was considered radiologically to represent widespread metastatic lymphadenopathy. Excisional biopsy of a supraclavicular lymph node, however, revealed chronic granulomatous lymphadenitis with a positive reaction of Tb-nested PCR. After antituberculosis treatment for 2 months, a follow-up CT scan showed complete resolution of the lesions. Intense 18F-FDG uptake could be due to an infectious process such as synchronous tuberculous lymphadenitis. Therefore, this could mimic a malignant condition such as lymphoma with extensive lymph node metastasis due to a false-positive finding, which may lead to a misdiagnosis.

Chlorination of swimming pool water leads to many chlorinated products. The most frequent derivative is trihalomethane(THMs). This study was performed to investigate the distribution of THMs in swimming pool water and ambient air, and to determine whether THMs concentrations in swimmers' urine Were influenced significantly after swimming. Water samples were collected from 22 indoor and outdoor swimming pools. Concentrations of THMs in swimmers' urine determined before and after their stay in swimming pools. Results of the study as follows. 1. The concentrations of THMs in the indoor swimming pools water(41.85±73.22㎍/L) were significantly increased(p<0.05) in comparison with that of outdoor swimming pools (10.15±15.45㎍/L). The average concentration of THMs in indoor ambient was 51.2㎍/㎥, which was significantly higher than that of air quality. 2. As a results of regression analysis between THMs and water quality factors, the concentration of pH, residual chlorine and KMnO₄ consumption were highly correlated in indoor swimming pools. 3. In almost all cases, only CHCl₃ was quantifiable. The proportions of THMs in urine correlated roughly with those in water and the secretion of THMs increased significantly after swimming in the pools.

The dike swarms exposed in Sancheong area are classified into intermediate and mafic dikes, which the intermediate one is more dominant. The dike swarms exhibit aphanitic (or aphanitic porphyritic) texture to very fine-grained granular texture, the latter is typical in the mafic dikes. The dike swarms intruded into all kinds of rocks such as Precambrian gneisses, anorthositic rocks and Mesozoic syenite with average thickness of 1 meter (range from 0.3 m to 10 m). The dike swarms occurred as average of N45°E strike with nearly vertical dip, which its strike coincides with the direction of major faults such as Baekmudong, Kwangjeomdong fa버ts in Jiri Mountains and unidentified faults in northern region of Sancheong. So we considered the dike swarms intruded along fractures anψor fracture zones related to the northeast strike of faults. Geochemistry of the dike swarms and stocks of diorite and gabbro closely related to the dike swarms spatially and temporally was discussed. The dike swarms and the related rocks belong to sub-alkaline rock series and represent the differentiation trend of calc-alkaline rock series. In geochemistry the dike swarms and diorite are similar to compositional variation of major elements, and primitive mantle- and N-type MORBnormalized abundance patterns of trace elements and REEs. Petrochemical characteristics indicate the origin of those rocks is identical as considered to be derived from a same magma. Parental magma of the dike swarms and diorite is concluded to be generated from partial melting of crustal materials such as amphibolite fusion. So diorite and the dike swarms are formed from crystallization of the magma derived from partial melting of amphibolite in the crust. Otherwise, gabbro displays some differences in abundance patterns of trace and rare earth elements. The primarγ magma of gabbro is assumed to be derived from partial melting of mantle peridotites. And gabbro is very similar to the gabbroic rocks occurred at Macheon 따ea in the mineralogy, geochemistry and rock types. In tectonomagmatic discriminant diagrams it is considered that all of the studied rocks are formed from magmas occurred in tectonic environment as continental margin anφor island arc that mean the destructive plate margin as subduction zone.

To measure temperature in microwave heating condition by thermocouple or thermistor is limited. In order to overcome this problem kinetics of ascorbic acid destruction was introduced. Activation energy for destruction of ascorbic acid was obtained under conventional heating condition. Arrehnius equation was used for prediction of rate constant under microwave vacuum heating condition. Then prediction of temperature could be obtained by using kinetic of ascorbic acid destruction that is calulated by the predicted rate constant.

Ulcerative colitis (UC) is a chronic inflammatory disorder of the gastrointestinal tract that affects the large bowel, Its etiology remains controversial. However, an infectious or immunologic origin is considered the primary cause. The onset of UC is typically slow and insidious, but some patients may present acutely with symptoms mimicking infectious colitis. We report a case of ulcerative colitis mimicking acute hemorrhagic colitis at initial presentation. A 60-year-old man was referred to Yeungnam University Hospital for bloody diarrhea and abdominal pain. Sigmoidoscopy revealed mildly edematous mucosa in the rectum and hyperemic mucosa with petechiae in the sigmoid colon. The patient was treated with antibiotics for several days, and his symptoms improved. However, after one month, his bloody diarrhea relapsed. Follow-up sigmoidoscopy revealed mucosal friability in the rectum and sigmoid colon. He was diagnosed with ulcerative colitis, and his symptoms were improved with mesalazine and a steroid enema.
