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.

Using several cationic polyelectrolytes of different charge density and molecular weight as flocculants and a simple continuous optical technique(photometric dispersion analyzer, PDA), the effects of mixing intensity and polyelectrolyte dosage on flocculation of kaoline particles(35 NTU) and particles(34.7 NTU) in Kangjung reversior of heavy rainfall have been examined. The optimum mixing was obtained at the stirring of 200rpm(G= 869 s^-1). The charge density of a polyelectrolyte is important in determining the optimum dosage and in the removl of particles. The optimum dosage is less for the polyelectrolyte of higher charge density and at the dosage, the removal of particles is higher for the polyelectrolyte of higher charge density and zeta potential of particles reaches to near zero. The optimum dosage for the removal of particles should be determined by flocculation test and not be determined by the turbidity of particles in water.

Purpose: We determined the use of scrotal ultrasonography in the initial diagnosis and management of testicular injuries due to blunt scrotal trauma. Mateiials and Methods: We reviewed 54 patients of scrotal trauma in the last 8 years. Forty patients were evaluated by ultrasonography preoperatively. A heterogeneous echo pattern of the testicular parenchyma with loss of oval shape, contour definition was the basis for diagnosis of testicular rupture. Among them, 33 cases underwent scrotal exploration and 7 cases were managed conservatively. The remaining 14 patients were evaluated only by physical examination, 8 patients of them were explored immediately because of suspicious testicular mpture. The accuracy of ultrasonography were determined by comparing radiographic interpretations with intraoperative findings. Results: Among the 33 patients who were evaluated by ultrasonography and explored immediately, there were 26 suspected testicular ruptures on ultrasonography. Surgical exploration revealed testicular rupture in 23 and simple hematoma in 10. The testicular rupture was correctly diagnosed by ultrasonography in the 22 cases, and there were 4 false-positive and 1 false-negative diagnoses of testicular rupture. The sensivity and specificity for the diagnosis of testicular rupture are 96% and 60%, and the positive and negative predictive values are 85% and 86%, respectively, Conclusions: Scrotal ultrasonography, with the main radiographic finding of a heterogeneous echo pattern of the testicular parenchyma with loss of oval shape, contour definition, is highly sensitive on the diagnosis of testicular rupture. And it increases the salvage rate for testicular rupture with preservation of the testicular function and prevents delayed complications of chronic pain, atrophy and orchiectomy associated with missed testicular rupture.

金京禮,崔文禎,李尙駿,朴炯國,金正漢 성균관대학교 약학연구소 1991 成均藥硏論文集 Vol.3 No.1

Abstract-After biotransformation of myrcene with Aspergillus niger KCCM 32005, its neutral metabolites were isolated from the conversion broths and analyzed by GC and GC/MS. Myrcene was converted into various terpenoids. Among them the five compounds, which were considered to be important as flavor, were identified as follows; terpinen-4-ol. α-terpineol, trans-carveol, cis-carveol, and carvone. Higher production was accomplished when the amount of myrcene was kept at lower but steady concentration by portion-wise introduction to the culture broth.

탄저는 탄저균이 동물에 감염되어 발병하는 인수 공통 질병이다. 탄저균의 아포가 감염되면 식균작용에 의해 대식세포 내로 들어가게 된다. 대식세포 내에서 아포는 발아하며 대식세포에서 숙주의 체내로 들어가게 된다. 치사독소는 방어항원과 치사요소로 구성되어있다. 방어항원은 세포의 탄저독소 수용체에 결합하여 방어항원에 결합한 치사요소를 세포내로 운반한다. 운반된 치사요소는 mitogen-activated protein kinase kinase (MAPKK)의 N-말단 부위를 전달하는 것으로 알려졌으나, 이 기작은 세포 사멸에 직접적인 영향을 주지 않는다. 탄저 치사독소에 의한 세포 사멸에 대한 많은 연구가 이루어지고 있으나, 그 기전이 아직까지 명확하게 규명이 되지 않고 있는 실정이다. 본 연구에서는 탄저 치사독소 처리에 의한 생쥐 대식세포주 (RAW 264.7)의 단백질의 발현양상을 조사하여 탄저 치사독소의 세포내 작용기작을 규명하고자 하였다. 단백질 발현 양상을 SELDI-TOF MS을 이용하여 분석하였다. 치사독소를 처리한 대식세포주에서 3,973 Da 단백질의 발현은 90분과 180분에 2배 정도 증가하였다. 단백질 6,066 Da의 발현은 60분에 두 배 증가하고 시간이 지남에 따라 점점 증가하였다. 단백질7,520 Da은 발현이 감소하고, 단백질 8,375 Da과 16,769 Da의 발현은 점점 감소하여 180분에는 절반으로 감소하는 경향을 보였다. MAPKKs가 절단되는 60분이 기준으로 점차 변화가 일어나는 이들 단백질은 치사독소의 절단된 MAPKKs에 의해 발현이 변화하는 것으로 추정되었다. Anthrax is an infectious disease caused by Bacillus anthracis. The spores of B. anthracis are accessed into the body and germinated in macrophages. B. anthracis secretes three virulence factors (such as, protective antigen : PA, lethal factor : LF, and edema factor : EF), and escapes destruction and lyse the macrophages by an unknown mechanism. Anthrax toxins play a central role in pathogenesis of anthrax. Lethal toxin (LeTx) is a mixture of PA and LF. LF is a zinc-dependent endoproteinase that cleaves the amino terminus of mitogen-activated protein kinase kinases (MAPKKs). The role of LeTx in mediating these effects is unknown, largely due to the difficulty in identifying and assigning function to individual proteins. To analyze the cytosolic protein profile of murine macrophages treated with LeTx, we have performed surface enhanced laser desorption/ionization time-of-flight mass spectrometer. The protein peak of 3,973 Da was increased 2 fold at 90 min and 180 min in murine macrophages treated with the LeTx. The protein peak of 6,066 Da was increased 2 fold at 60 min and gradually increased at 90 min and 180min. Protein peak 8,973 Da and 16,769 Da was decreased 2 fold in 180 min. Our results suggest that these proteomic approaches are a useful tool to study gene and protein expression in intoxicated macrophages.
