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.

Diffraction grating in a holographic polymer dispersed liquid crystal based on polyurethane acrylate
Kim, EunHee,Woo, JuYeon,Kim, ByungKyu Taylor Francis 2007 Liquid crystals Vol.34 No.1
<P> Diffraction modes of holographic grating were fabricated with polyurethane acrylates of various monomers, and with various film compositions, irradiation intensities, cell gaps and reading angles. An optimum monomer composition, LC content and irradiation intensity were obtained in terms of diffraction efficiency. Of the two types of multifunctional acrylate examined, dipentaerythritol penta-/hexa-acylate (DPHPA) gave better diffraction efficiency than the trimethylolpropane triacrylate (TMPTA) throughout the monomer compositions tested. This was interpreted in terms of high elasticity of the high functionality monomer. The existence of an optimum irradiation intensity at fixed resin composition was interpreted in terms of optimum rate of cure. A monotonic increases of diffraction efficiency with cell gap and interbeam angle were also noted, implying that the grating was formed uniformly as visualized by scanning electron microscopy.</P>

Objective: This study aimed to evaluate the procedure-related fetal loss and the obstetrical outcomes of chorionic villus sampling and amniocentesis in twin pregnancies. Methods: The data from dichorionicdiamniotic twin pregnancies for which first-trimester chorionic villus sampling or second-trimester amniocentesis was performed between December 2006 and January 2017 at a single institute, were retrospectively analyzed. The groups were compared with respect to the procedure-related and obstetrical outcomes. Results: The difference in procedure-related fetal loss rate (1.9% for chorionic villus sampling vs. 1.8% for amniocentesis; P=1.000) and overall fetal loss rate (7.4% for chorionic villus sampling vs. 4.7% for amniocentesis; P=0.489) between the two groups was not significant. The difference in miscarriage rate and early preterm delivery were not significant between the groups (miscarriage: 5.6% for chorionic villus sampling vs. 0.6% for amniocentesis; early preterm delivery: 11.1% for chorionic villus sampling vs. 10.6% foramniocentesis; P=NS). The differences in mean gestational ages at delivery, birth weights, and neonatal intensive care unit admission rate were not statistically significant. Conclusion: To our knowledge, this is one of the few studies to compare chorionic villus sampling and amniocentesis in twin pregnancy, including procedure-related fetal loss. The procedure-related fetal loss and the overall fetal loss of chorionic villus sampling appear comparable to those of amniocentesis. Both procedures can be safely used based on several factors: indications, gestational age, technical difficulties, the likelihood to proceed to selective feticide, and operators experience. These findings can be useful for clinicians when counseling parents of twins regarding their options for antenatal aneuploidy, genetic diagnosis, and the associated risks. Furthermore, randomized controlled trials are required to compare the safety of chorionic villus sampling and amniocentesis in twin pregnancies.

Aspects of the Acceptance of Hanja and Its Identity in the Korean Society
Eunhee KIM 경성대학교 한국한자연구소 2016 한자연구 Vol.0 No.14
This paper examines aspects of the acceptance and identity of Hanja (Chinese characters borrowed from Chinese and incorporated into the Korean language with Korean pronunciation) in the Korean society, and analyzes the literal and social mechanism employed for continued acceptance by the Korean public. The analysis illuminates insight into the social status and recognition of Hanja in the Korean society. In the ancient Korean society, Hanja was identified as a textual existence dominating the thoughts of the intellectuals and reproducing knowledge. Though its stature and status of the past are no longer present, Hanja still retains a remnant of their past stature in the contemporary Korean culture. In Korea’s popular culture, Hanja is used in various kinds of notices, signs, trademarks, and advertisements. In the consumer market, in particular, Hanja represents the Oriental sentiments and beauty and traditional authority, surpassing the realm of the text beyond borders of the elegant () or the folksy () to the level of an iconic entity of knowledge, whose symbolic images are used as marketing strategies in the consumer market.

<P><B>Abstract</B></P><P>Apoptosis-inducing factor (AIF) is a ubiquitous FAD-binding flavoprotein comprised of 613 amino acids and plays an important role in caspase-independent apoptosis. During apoptotic induction, AIF is translocated from the mitochondrial intermembrane space to the nucleus, where it interacts with DNA and activates a nuclear endonuclease. By performing a yeast two-hybrid screen with mature AIF, we have isolated the eukaryotic translation initiation factor 3 subunit p44 (eIF3g). Our deletion mutant analysis revealed that the eIF3g N-terminus interacts with the C-terminal region of AIF. The direct interaction between AIF and eIF3g was confirmed in a GST pull-down assay and also verified by the results of co-immunoprecipitation and confocal microscopy studies. Using an in vitro TNT coupled transcription–translation system, we found that mature AIF could inhibit newly-translated protein synthesis and this inhibition was significantly blocked by eIF3g competitively. These results were also confirmed in cells. In addition, mature AIF overexpression specifically resulted in the activation of caspase-7, thereby amplifying the inhibition of protein synthesis including eIF3g cleavage. Our data suggest that eIF3g is one of the cytosolic targets that interacts with mature AIF, and provide insight into the AIF’s cellular functions of the inhibition of protein synthesis during apoptosis.</P>
