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.

Background: Triple-negative breast cancer (TNBC) is a heterogeneous entity that encompasses several subtypes with distinct molecular characteristics. The patients with TNBCs show unpredictable response to the chemotherapy, and further there is the lack of effective agents. Thus, many studies have been underway to discover targeted therapy suitable for patients with specific genetic alterations in each molecular subtypes. TNBCs are classified as four major molecular subtypes according to the gene expression patterns. These are luminal androgen receptor (LAR), mesenchymal-like, immunomodulatory (IM), and basal-like types. Conclusion: Here, we discuss the unique molecular features of each subtype as well as promising targets for anti-cancer therapy.

Iliac vein compression syndrome is a rare clinical condition in which left common iliac vein is anatomically compressed between right common iliac artery and the fifth lumbar vertebrae or pelvic brim. Patients usually have marked edema of the left leg. Although the actual incidence is unknown, this syndrome most affects women in the second to fourth decade of life. We report 4 cases of iliac compression syndrome treated by surgical intervention during the last fifteen-year period. Among them, two women have suffered from chronic intermittent swelling and pain of left leg, and two men had acute or subacute symptoms. The fibrous web in the entrance of left iliac vein into vena cava existed in one case. Including this one, two were treated by transposition of iliac artery or vein with thrombectomy. One was decompressed the arterial compression by mobilization or adhesiolysis of the surrounding vessles with thrombectomy. To the last one in which the distal common iliac vein was compressed by tortous dilated left internal iliac artery, transsection and ligation of the internal iliac artery was performed. All patients have experienced improved left leg condition after operation. except the last one in which suffered from thrombosis of left popliteal vein after the iliac decompression.

Background: Recently, The number of patients who have been complaining of the vertigo or dizziness has been increasing due to rapid growth of elderly population and senile disease. The differentiation of dizzy patients is not familiar to most emergency physicians. This study was designed to differentiate true vertigo and to investigate the clinical difference among central vertigo, peripheral vertigo, and other causes of dizziness. Methods: The authors analyzed the cases of 237 dizzy patients who visited the emergency department of Chonnam University Hospital during the recent 2 years. For the base of dizziness, associated past illnesses, severity, nystagmus type, and the causes of central and peripheral vertigo. Results: Female patients were 142(59.9%) and male patients were 95(40.1%). The most common age group was the 6th decade. The origin of dizziness was classified as peripheral cause(25.3%), central cause(32.9%), and others(41.8%). As to nature of the dizziness, the rotatory sense was dominant in peripheral vertigo and the floating sense and blurred vision in central vertigo. Peripheral vertigo was triggered by position change of head and body, and central vertigo by the eye movement. Audiograms I showed that most patients with central vertigo had normal hearing, but 46.7% of thoswith peripheral vertigo had an abnormal hearing disturbance. Nystagmus was more prevalent in peripheral vertigo Conclusion: History taking and physical examination played an important role in the diagnosis of dizzy patients. An important part of the diagnosis of a dizzy patient could be to evaluate the peripheral origin, the central origin and others causes. Because central vertigo may be associated with a significant neurological pathology, spectral radiological studies, including MRI and CT, are mandatory to rule out a devastating brain lesion.

시험용 달 궤도선의 발사 요구조건 사전 분석 단계로 최근 외국에서 발사한 달 탐사선의 발사 요구조건을 분석하였다. 일반적으로 달 탐사선의 발사 요구조건은 달 임무 궤도를 결정하는 중요한 요소이며, 또한 지구, 달, 태양의 상대적인 운동으로 인해 임무궤도 요구조건을 만족하는 발사 가능 시간이 주기적으로 반복되는 경향이 있다. 분석 결과 설정된 발사 요구조건들로부터 달 궤도선의 주 임무가 달의 남/북극 지역의 광학 관측 임을 간접적으로 알 수 있었다. 향후 우리나라 달 궤도선 발사 요구 조건 설정에 본 논문이 도움이 되길 기대한다. In the preliminary study on launch window requirement for Korea Path-finder Lunar Orbiter(KPLO), the recent foreign lunar orbiter’s lauch window requirement was analyzed. Normally, the launch requirements depends on the mission orbit. Based on the relationship between Moon, Earth, and Sun, the launch time will be available periodically to meet requirements. In this paper, it is understood that the launch window requirements come from payload mission requirements to take picture each poles of Moon. This paper might be a practical example to derive KPLO launch requirements in the future.

포물선 아치 리브는 원형 아치 리브와 더불어 실무에 폭넓게 적용되고 있는 아치 형상이다. 원형 아치 리브의 비탄성 면내 거동에 관한 연구는 1990년대 Trahair(1996)를 중심으로 연구가 진행되었으며, Yong-Lin Pi와 Bradford(2004)에 의하여 최근까지 연구가 활발히 진행 되고 있다. 포물선 아치 리브의 비탄성 면내 거동에 관한 연구는 일본의 연구자(Sinke, Kuranishi)을 중심으로 1970년대 후반부터 1980년대 초반에 이르기까지 많은 연구가 진행되었다. 이러한 포물선 아치 리브에 관한 일본에서의 연구는 대부분 라이즈비가 <TEX>$0.1{\sim}0.2$</TEX>에 국한 되어있다. 본 연구에서는 비탄성 유한요소해석을 이용하여 라이즈비가 0.1에서 0.4에 이르는 박스형태의 단면을 갖는 포물선 아치 리브의 면내 거동에 관하여 연구를 수행하였다. 연구 결과 라이즈비가 증가할수록 아치 단면에 휨모멘트가 증가하였으며, 압축력이 수직 등분포 하중을 받는 포물선 아치 리브의 면내 좌굴 안정성에 미치는 영향은 감소하였다. 마지막으로 본 연구에서는 아치 리브를 따라 작용하는 수직등분포 하중을 받는 포물선 아치의 좌굴 곡선을 제안하였다. Parabolic arch ribs are widely used in practical. In case of circular arch ribs. Inelastic in-plane buckling behaviors were investigated by Trahair(1996). Recently Yong-lin Pi & Bradford(2004) investigated about in-plane design equation for circular arch ribs. In <TEX>$1970{\sim}1980$</TEX>. In-plane buckling strength about parabolic arch ribs were studied by some japan researchers (Sinke, Kuranishi). Study results of Sinke & kuranishi are only valid for rise-span ratio <TEX>$0.1{\sim}0.2$</TEX>. In this paper. The researchers investigated about in-plane inelastic buckling behaviors of parabolic arch ribs having rise-span ratio from 0.1 to 0.4. From the results. When the rise-span ratio increase, flexural moments increase and influence of axial force to in-plane buckling strength decrease. Finally, buckling curves for parabolic arch ribs subjected distributed loading along the axis were suggested.

Background: Although cardiopulmonary resuscitation(CPR) is a very effective therapy in cardiac arrest, it is hard to prove the true effectiveness of CPR. Several studies about out-of-hospital and emergency department CPR exist, but only a few reports about in-hospital CPR are available. This study was designed to investigate in-hospital cardiac arrest, to analyze the result of CPR, and to evaluate the problems associated with in-hospital CPR. Methods: A clinical analysis of 71 cases of in-hospital CPR announcement from January 2000 to August 2000 was performed. The initial rhythm on cardiac arrest, return of spontaneous circulation(ROSC), and the survivals were analyzed in the case of the 46 true cardiac arrest patients. Results: During 8 months, there were 71 cases of in-hospital CPR announcement. Among them, there were 46 cases of true cardiac arrest and 25 cases of non-cardiac arrest. Of the 46 true cardiac-arrest cases, 27(58.7%) experienced ROSC, 15(32.6) survived for over 24 hours, and 7(15.2%) survived to be discharged. The initial rhythms on cardiac arrest were 30 cases(65.2%) of asystole, 14(30.4%) of PEA(pulseless electrical activity), and 2(4.3%) of ventricular fibrillation, with ROSC being 17 cases(56.7%), 9(64.3%) and 1(50.0%) cases and discharged survivors being 4 cases(13.3%), 3(21.4%) and 0(0.0%) cases, respectively. Conclusion: Extraordinarily high proportions of asystole and PEA were seen in the initial rhythm of cardiac arrest, and those were associated with high survival rates. Although further study is needed to evaluate the course leading to this high proportion of asystole and PEA, this result suggests that if the EMS system in the hospital is activated promptly and systematically, a better outcome will be achieved in case of cardiac arrest with asystole and PEA.
