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 and Objectives : Many students major in applied music singing have various difficulties in phonation when they sing or perform. But the studies about this cause are lack. The purpose of this study is whether singing voice therapy based on vocal music is effective or not to applied music singing students that have difficulties in phonation. Materials and Methods : Singing voice therapy program had been done to 8 students major in applied music singing during 7 weeks. We did laryngeal stroboscope, perceptual, acoustic and aerodynamic examination before and after singing voice therapy to this students. And we studied post examination results have differences or improvements compared to pre examination results. Results : Four male students don't have effective improvement after singing voice therapy but they shows slight improvement in aerodynamic examination values compared to pre examination values. Four female students shows improvement in aerodynamic examination values and pitch range increasing. Above all, one student's vocal nodules disappeared after singing voice therapy. Conclusion : Singing voice therapy based on music singing is very effective to the students major in applied music singing. Above all, their curriculum in applied music singing should include phonation training based on music singing before training perform and technic practices.

In this paper, an environment map bulding for the mobile robot navigation using a stereo camera system is studied. First of all, distance measurements are necessary to build the environment map. So, a distance measurement method using two fixed cameras is presented. To measure the distance using a stereo vision system, finding the common points in the left and the right images are needed. In this study, an area-based stereo matching is used to solve this problem. To reduce the computation time, 1) the DSP processor on vision board is used, 2) suitable sizesearch region for environment is taken, 3) small size model for matching is used, and 4) hierarchical search method is used. Also, a simple movement method is presented to make an environment map for mobile robot. Finally, the presented method is proved experimentally. The images of a corridor are taken by a stereo camera, and the distances of a corridor are obtained fast using the presented method from the images. And then, the environment map for the navigation of mobile robot is constructed. The acquired map is helpful for understanding the environment.

The purpose of this study was to develop a new ^13C-urea- containing capsule for diagnosis of H. pylori. The urea-containing capsules were prepared with various diluents such as polyethylene glycol (PEG), microcrystalline cellulose, sodium lauryl sulfate and citric acid. The dissolution test, ^13C-urea breath test and stability test were then performed on the capsules. Microcrystalline cellulose and sodium lauryl sulfate retarded the initial dissolution rates of urea. However, PEG increased the initial dissolution rates of urea. Furthermore, two formulae composed of PEG, [^13C-urea/PEG (38/1.9 mg/cap)] and [^13C-urea/PEG/citric acid (38/1.9/1.9 mg/cap)] had the maximum DOB value, about 16 at 20 mim, while the formula composed of only 38 mg ^13C-urea had the maximum DOB value at 30 min. The results indicated that PEG improved the sensitivity of ^13C-urea in the human volunteers. The capsule [^13C-urea/PEG (38/1.9 mg/cap)] was stable for at least six months in 25 and 37℃. Thus, a PEG-containing capsule, [^13C-urea/PEG (38/1.9 mg/cap)] would be a more economical, sensitive and stable preparation for diagnosis of H. pylori.

실험적 치아이동에 의한 백서 치주인대내 CGRP 면역 양성 신경섬유의 변화

교정력에 의하여 치주인대내에 생긴 압박측에서는 국소적 염증반응과 골 흡수가 활발히 일어나며 신장측은 골 생성이 활발하므로 뒤 두 부위는 서로 다른 조직반응이 일어난다. 치아이동에 관여하는 것으로 알려진 CGRP 면역 양성 신경섬유도 압박 및 신장 부위에 따라 다를 것으로 생각된다. 저자등은 CGRP 면역 양성 신경섬유의 교정력 적용시간에 따른 변화를 관찰하고 압박 및 신장력을 받는 부위에 따른 변화를 관찰하기 위하여 200gm 내외의 생후 9주령 백서 상악 제1 대구치에 Ni-Ti coil spring으로 80gm내외의 교정력을 12시간, 1일, 3일, 7일, 12일동안 가한 후 희생하여 면역 조직화학법으로 염색하여 관찰하였다. · 교정력 적용 12시간 및 1일군에서 압박 및 신장측 모두에서 CGRP 면역 양성 신경섬유가 감소되었다. · 교정력 적용 3일군에서 CGRP 면역 양성 신경섬유는 많은 가는 분지가 관찰되며 증가되었고 특히 신장측에서 현저하였다. · 교정력 적용 7일군에서 비교적 굵은 CGRP 면역 양성 신경섬유도 증가 되었으며 신장측에서 현저하였다. · 교정력 적용 12일군에서 압박측 치주인대에서는 거의 정상과 유사하였으나 신장측치주인대에서는 증가된 채 유지되었다. · CGRP 면역 양성 신경섬유는 압박측보다 신장측에서 더 많이 증가하여 치아이동시 CGRP가 말초조직에서 염증반응에 관여함과 동시에 골 개조에도 상당한 연관성을 가지고 있을 것으로 생각된다. Bone resorption was predominate in compression site, bone formation in tension site of periodontal ligament during tooth movement. The biologic response at compression site was different from tension site. Thus the CGRP immuno-positive nerve fiber will respond differently to mechanical force according to the area(compression or tension site). The purpose of this study was to investigate this response of CGRP immuno-positive nerve fiber in the periodontal ligament according to the duration of applied force and the area (compression or tension site) during experimental tooth movement. The experimental animals were 7 week old male rat (approximately 200 gm). The orthodontic force was applied mesially to the right maxillary molar using the Ni-Ti coil spring during 12hours, 1, 3, 7, and 12days. Immunohistochemical staining using antibody against CGRP was performed after sacrifice. The results were as follows. The CGRP immuno-positive nerve bundle showed reduced immunoreactivity and nerve fibers reduced in density after application of orthodontic force for 12 hours and 1day. The CGRP immuno-positive nerve fibers showed many thin branches at the apical periodontal ligament after application of force for 3 days as compared with normal. The tension site in the apical periodontal ligament showed more branches than the compression site. In 7 day group, the CGRP immuno-positive nerve fibers increased in terms of the number and had many thin branches in the apical periodontal ligament. The tension site had more branches than the compression site. In 12 day group, the CGRP immuno-positive nerve fibers showed similar distribution to normal control at compression site of apical periodontal ligament, but the fibers at the tension site increased in number. The CGRP immuno-positive nerve fibers showed more increased at tension site than compression site after application of orthodontic force. Therefore it seems to have some relation to the bone remodeling besides the local inflammatory process.

데이빗 트레이시(David Tracy)의 신학적 언어로서의 유비적 상상력(analogical imagination)

노영상 국제기독교언어문화연구원 1997 기독교언어문화논집 Vol.1 No.-

Yong Sang No. 1997. Analogical Imagination As the Theological Language of David Tracy- Collected Papers on Christian Language Culture. David Tracy, a American theologian, who teaches in Chicago University, suggests analogical imagination as a theological language for this pluralistic situation. He, as a revisionist theologian, says that theology has to be built up by public discourse in order that nonchristians amy understand it. He embraces both the liberal theology emphasizing human experience and the neo-orthodox theology emphasizing divine revelation into his theology of analogical imagination. His analogical language includes similarities-in difference and radical dissimilarity-in- similarity as a dialectical phase. This analogical vision makes the conversation with others possible. He developed conversation theory from the foundation of the comtemporary hermeneutics.(Ho Nam theology seminary)
