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 contents of Han Yul Byung(寒熱病) are explained on the basis of the so-called theory "Yin and Yang, the Five Evolutive Phases(음양오행)". The text of the Han Yul Byung(寒熱病) of the Young Chu(靈樞) was written in the Kap Ul Kyung(甲乙經) chapter 5, 7, 8, 10, 11 and 12. Also it was written in the Tae So(太素) volume 10 and 26. Also it was introduced in the Ryu Kyung(類經) volume 20, 21 and 22 by Jang Kae-Pin(張介賓) in the Myung(明) dynasty. Summarizing the contents of the Han Yul Byung in reference to the contents of successive generation note, the contents run as follows: Chapter 1 deals with the symptoms and treatment of diseases which accompany chills and fever(寒熱病). Chapter 2 deals with arthralgia with other joint systems(骨痺) and flaccid paralysis of Iimbs(體惰病). Chapter 3 deals with indications of five points around the Chen You Points(天牖穴). Chapter 4 deals with the treatment of toothache. Chapter 5 deals with the treatment of headache and eye pain. Chapter 6 deals with the acupuncture manipulation according to changes of season. Chapter 7 deals with the serious influence of carbuncle according to the region of body. Chapter 8 deals with the treatment of heat-syndrome. Chapter 9 deals with the side effect of acupuncture. It is too difficult to understand the Han Yul Byung(寒熱病), because it is written in old chinese. Consequence of above reason, the writer of this article has researched to find out the exact meaning of that.

As the device geometry shrinks to the deep submicron region, chemical mechanical polishing(CMP) planarization become a more essential technique of advanced ULSI process. Also, CMP process was required for the global planarization of inter-metal dielectric(IMD), inter-level dielectric(ILD) layers and interconnections with free-defect. Especially, the complete global planarization of IMD, ILD and interconnections can be achieved only with the CMP process. However, as the IMD and ILD layer gets thinner, several problems were found in the CMP process. It does have various problems such as dishing effect, torn oxide defects and nitride residues in oxide. So, it leads to severe circuit failure, which affects yield. In this paper, we studied the characteristics of polishing pad, which can apply STI-CMP process for global planarization of multilevel interconnection structure. Also, we investigated the effects of different sets of polishing pad, such as soft and hard pad. As an experimental result, hard pad showed center-fast type, and soft pad showed edge-fast type. Totally, the defect level has shown little difference, however, the counts of scratch was defected less than 2 on JR111 pad. Through the above result, we can select optimum polishing pad, so we can expect the improvement of throughput and device yield.

Objectives : The purpose of this study was to determine the factors affecting smoking cessation rate of heavy smokers. Methods : Typically, 81 participants enrolled in the smoking cessation camp at Chungbuk National University Hospital from April 2016 to November 2016 were included in the present study. The psychological factors related to group classification and the factors related to the success of smoking cessation were analyzed. Results : After 24 weeks of leaving the camp, 57 out of 81 participants successfully quit smoking and 24 failed in doing so. In the successful group, depression scale, stress scale, and various smoking-related factors exhibited intercorrelation and in the failure group, no significant correlation was observed. However, a comparison of correlation coefficients showed no significant difference. In addition, smoking cessation success rate was low when exhaled CO concentration was high at the time of admission when the smoking initiation age was juvenile, and when the smoking type was A (stimulus seeking type). Conclusion : Exhaled CO concentration at the time of admission, smoking initiation age, and smoking type A (stimulus seeking type) were associated with smoking cessation success.

Mucormycosis is an opportunistic fungal infection caused by the mucorales, which consist of the Rhizophus, Absidia, Mortierella, and Mucor. The diverse clinical forms of mucormycosis can be categorized as rhinocerebral, pulmonary, disseminated, gastrointestinal, cutaneous and miscellaneous. Although it can cause disease in healthy people, it most commonly affects patients who are diabetic or immunosup-pressed. Rarely, mucormycosis develops confined to the subcutaneous tissue. We experienced a case of cutaneous mucormycosis developed in a well-controlled diabetic patient who had previously injected foreign material on her face for an aesthetic purpose at the behest of an unlicensed physician. The patient had tissue necrosis and purulent discharge on her left cheek. Following histologic examination, we diagnosed the condition as cutaneous mucormycosis and treated it by wide excision combined with amphotericin B therapy. The disease was cured without any significant sequelae within 6 months of follow up. Cutaneous mucormycosis is rarely reported but it can cause facial deformity due to tissue necrosis, so that early diagnosis and appropriate treatment are important. Currently, foreign material injection for aesthetic purposes is still performed by unlicensed physicians. We present a case report concluding that one should consider the possibility of fungal infection in skin lesion in diabetic or other immunosup-pressed patients. We also emphasize the seriousness of illegal injection of foreign material.

Background: ST segment elevation in patient with chest pain was seen in acute myocardial infarction and in numerous other non-infarction syndromes. The causes of non-infarction syndrome were left ventricular hypertrophy, BER(benign early repolarization), and left bundle branch block in cardiac origin and were hyperkalemia and hyperventilation syndrome in metabolic origin and were others. Furthermore, the differentiation of electrocardiogram between acute myocardial infarction and non-infarction syndrome was very difficult. So, we compared and analysed characteristics of ST segment elevation of acute myocardial infarction and non-infarction syndrome that suggested the clue of early diagnosis of coronary artery disease. Method and Materials: We retrospectively reviewed the electrocardiogram of 961 patients with chest pain who visited the emergency center from January 1999 to December 1999. Acute myocardial infarction was diagnosed by clinical finding, electrocardiogram, cardiac enzyme, echocardiogram, and myocardial spect. Left ventricular hypertrophy, BER, and left bundle branch block in cardiac origin of non-infarction syndrome were diagnosed by electrocardiographic criteria suggested by William J. Brady. Acute myocarditis, acute pericarditis, and hyperventilation syndrome were diagnosed by clinical finding. Results: Among 961 patients with chest pain, 236(24.6%) patients manifested ST segment elevation who were diagnosed acute myocardial infarction in 162(68.6%) patients and non-infarction syndrome in 74(31.4%) patients. The causes of non-infarction syndrome in 74 patients were left ventricular hypertrophy(32:13.6%), BER(28:11.9%), left bundle branch block(11:4.7%), and others(3:1.3%). Three others were acute myocarditis, acute pericarditis, and hyperventilation syndrome. Electrocardiographic characteristics of ST segment elevation of non-infarction syndrome manifested almost same finding compared to William J. Brady' criteria. Conclusion: ST segment elevation in patient with chest pain visited emergency department was seen in acute myocarction(68.6%) and the other non-infarction syndromes(31.4%). Significant number of patients were not associated with acute myocardial infarction. Therefore, we must completely understand characteristics of ST segment elevation in acute myocardial infarction and the other non-infarction syndreomes to diagnose fatal early coronary artery disease and to avoid unnecessary thrombolytic therapy.
