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.

At here, we investigated the historical background, current stage, and concrete therapies of altematives in cancer therapy. We obatined the conclusion below. 1. Alternative medicine(AM) is a unothodoxial medical physiology, medical practice or intervension that overcome the side effects. faults, limits of coventional medicine. 2. Recentely, as emerging New-age movement, collgpse of Decarte's mecanical cosmology, and emphasis on patient rights, the interest of AM is increased, and foreign & domestic use rates of AM are risen. 3. After coventional medicine in cancer therapies tha depends on poerations, radiations, and chemotherapy is bounded, Altematives in cancer therapy are rapidly developed, and the majority of users are often considered satisfactory. 4. Alternatives in cancer therapy are classified six boundaries; Diet and Nutrition, MInd-body Technique, Integrated System, Pharmacologic and Biologictreatments, Immuno Enhanced Therapy, Immuno Enthaced Therapy, Natural and herbal medicine. 5. Looking at contents of Alternatives in cancer therapy, we get to know most of them are similar to the treatment of oriental medicine in holistic method, therapy, philosophy. If we synthesize the alternative medicine's treatment mentioned above and investigate it with oriental medical viewpoint, that may help us approach the conquest of cancer and improve the rate of cure. that may help us approach the conquest of cancer and improve the rate of cure. 6. It is certain that foreign AM will be imported reversely, and we must prepare for rebuilding of Korean traditional AM systemically, investing for activity positively, making national policy for medical system.

폐암에 대한 직업의 관련성을 밝히기 위하여 1993년 11월에서 1994년 8월까지 대구 시내 2개 종합병원에 입원하여 병리 조직학적으로 진단된 168명의 폐암 환자와 같은 병동에 있는 내과 환자를 연령군과 성별로 빈도 짝짓기하여 168명의 대조군으로 선정하였다. 직업력과 유해 물질의 폭로력, 거주 환경, 흡연에 관한 정보는 설문지를 통하여 얻었다. 흡연 상태를 보정하고 연령군과 성별에 대한 짝지은 자료에 대하여 직업과 산업 분류에 대한 폐암 발생의 상대 위험은 농업 종사자에서 유의하게 높았고(OR=1.84 ; 95% 신뢰구간 1.16-2.94) 생산직, 가내 수공업, 운수창고통신업, 숙박음식업, 건설업에서도 높게 나타났으나 유의하지 않았다. 그러나 가사(OR=0.31 ; 95% 신뢰구간 0.11-0.89), 관리직(OR=0.22 ; 95% 신뢰구간 0.08-0.61), 공공 행정업(OR=0.23, 95% 신뢰구간 0.08-0.66), 공공 사회및 개인 서비스직(OR=13 ; 95% 신뢰구간 0.03-0.56)에서는 폐암 발생의 상대 위험이 유의하게 낮았으며, 전문직, 도소매업에서도 낮게 나타났으나 유의하지 않았다. 거주 환경에 따른 폐암 발생의 상대 위험은 연탄난로 사용자(OR=3.00 ; 95% 신뢰구간 1.06-8.52)와 농약 사용시(OR=2.14 ; 95% 신뢰구간 1.36-3.37)에 통계학적으로 유의하게 높았고, 공장지대 거주자에서도 높게 나타났다(OR=1.97 ; 95% 신뢰구간 0.92-4.27) 그러나, 중앙집중식난방사용자(OR=0.5 ; 95% 신뢰구간 0.28-0.89)에서는 낮게 나타났으며 통계학적으로 유의하였다. 유해 물질 폭로에 따른 폐암 발생의 상대 위험은 농약(OR=2.07 ; 95% 신뢰구간 1.31-3.26)과 용접 및 흄(OR=10.56 ; 95% 신뢰구간 1.07-103.90)에 폭로시 유의하게 높게 나타났다. 흡연에 의한 폐암 발생의 상대 위험은 비흡연자에 비하여 흡연자(OR=3.98 ; 95% 신뢰구간 1.88-8.45)와, 과거흡연자(OR=4.50 ; 95% 신뢰구간 1.99-10.16)에서 높게 나타났다. 이상의 결과로 비록 흡연이 폐암의 중요한 원인이지만 흡연의 영향을 보정한 후에도 대기오염 및 직업과 폐암과 관련성이 있음을 보여주고 있으며, 앞으로 이러한 직업에서 어떠한 위험 요인이 있는지에 대한 추구가 필요하여 그에 대한 예방 대책을 밝히는 연구가 필요하다. The relationship between occupation and risk of lung cancer was analyzed in hospitalbased case-control study conducted in Taegu on 168 patients with histologically confirmed lung cancer and age group(30-39, 40-49,etc) and sex frequency-matched 168 controls admitted into hospitals for other internal medicine problems. A self adminstered questionnaire was used to obtain occupation, resident environment, smoking histories and specific agent exposure history. The conditional logistic regression was used to estimate oddsratio for age group and sex frequency matched, after controlling for smoking status(non smoker, exsmoker, current smoker) Significant association was observed for farmer[odds ratio(OR), 1.84 ; 95% confidence interval(CI), 1.16-2.94], briquette stove users[OR, 3.0 ; 95% CI, 1.06-8.25], agricultural chemicals users[OR, 2.14 ; 95% CI, 1.35-3.37], and welding/fume exposures[OR, 10.56 ; 95% CI, 1.07-103.90]. Although there were elevated risks associated with production, home industry, transportation/storage/communication, lodgement/food worker and construction, none were statistically significant. The effect of smoking was showed significantly increased risk for exsmoker [OR, 4.50 ; 95% CI, 1.99-10.16] and current smoker [OR, 3.98 ; 95% CI, 1.88-8.45]. As results, although smoking is important risk of lung cancer, occupation and resident environment are showing association of lung cancer. So further evaluation is necessary for occupation risk and take preventive measures.

이진경,민선홍,홍성태,오소람,정신혜,황영혜,유성엽,배광식,백승호,이우철,손원준,금기연 대한치과보존학회 2009 Restorative Dentistry & Endodontics Vol.34 No.2

This clinical study evaluated the whitening effect and safety of polymer based-pen type BlancTis Forte(NIBEC) containing 8.3% carbamide peroxide. Twenty volunteers used the BlancTis Forte whitening agent for 2 hours twice a day for 4 weeks As a control. Whitening Effect Pen (LG) containing 3% hydrogen peroxide was used by 20 volunteers using the same protocol. The change in shade (ΔE^(*) color difference) was measured using Shadepilot™ (DeguDent) before, during and after bleaching (2 weeks, 4 weeks and postbleaching 4 weeks). A clinical examination for any side effects (tooth hypersensitivity or soft tissue complications) was also performed at each check-up. The following results were obtained. 1 Both the experimental and control groups displayed a noticeable change in shade (ΔE) of over 2 No significant differences were found between the two group (p>0.05) implying that the two agents have a similar whitening effect. 2 The whitening effect was mainly due to changes in a and b values rather than in L value (brightness). The experimental group showed a significantly higher change in b value thus yellow shade than the control(p < 0.05) 3 None of the participants complained of tooth hypersensitivity or soft tissue complications confirming the safety of both whitening agents 8.3%의 carbamide peroxide를 함유한 펜형 코팅용 미백제인 BlancTis Forte (NIBEC, Seosul & JinCheon)를 실험군으로, 3% hydrogen peroxide를 함유한글 Whitening Effect Pen (LG. Seoul) 제재를 대조군으로 각각 피험자 20명에게 2시간씩 1일 2회 제조사의 지시대로 치아표면에 4주간 적용하도록 지시하고 색조개선 효능과 안전성을 평가하였다. 미백 효과는 미백 전 및 미백 2주, 4주 및 미백 종료 4주 후에 Shadopilot™을 이용하여 색 변화를 측정하였고, 매 내원시기마다 모든 환자는 치수생활력 검사와 치주 및 치태 검사를 통해 부작용 여부 (치아과민증 및 구감 내 연조직의 부작용)를 기록한 후 다음과 같은 결과를 얻었다. 1.실험군 및 대조군의 색 변화량 (ΔE)은 2이상으로 인지할 수 있는 색 변화를 보였으며, 두 제품 간에는 통계적으로 유의한 차이를 보이지 않아 (p > 0.05) 유사한 미백효능을 나타냄을 알 수 있었다. 2,미백효과는 명도의 개선보다는 주로 a. b값의 변화에 의한 것으로 특히 실험군에서 b값의 변화, 즉 황색조의 개선효과가 대조군에 비해 유의성 있게 높은 것으로 나타났다 (p <0.05). 3.치아나 치은의 과민증이나 이상증상을 호소하는 피험자는 없어 두 제품 모두 안전성을 확인할 수 있었다.
