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.

본 연구에서는 그림 속으로의 여행 기법을 구현하였으며, 마우스 및 키보드를 대신하여 제스처 인식을 사용함으로서 네비게이션이 쉽고 편리해짐을 증명하였다. 그림속으로의 여행 기법은 한 장의 영상으로부터 간단한 방법으로 3차원 애니메이션을 만들 수 있는 기술이다. 본 연구에서는 기존의 Horry 및 Pho가 제안한 방법을 PC가 제안한 방법을 PC상에서 구현하여 2차원 영상을 3차원 네비게이션이 가능한 영상으로 변화하였다. 사용자 인터페이스인 손 모양 제스처의 인식을 크게 3개의 타입으로 개발되었으며 Type-1은 대기(wait)를, Type-2는 2D 상의 각종 방향 지시를, Type-3는 3D 공간상의 위와 아래를 지정할 수 있도록 설계되었다. 개발된 세 타입의 손 제스처는 3D 랜더링된 영상속에서 가상 마우스 및 키보드의 역할을 담당하며, 이러한 손 모양 제스처를 이용함으로서 사용자는 3D 공간상에서 자유롭고 간편하게 투어링이 가능해 졌다. The purpose of this study is to prove that using gesture recognition through implementing the method of 'tour into the picture' makes navigation very convenient and easy compared to navigation using mouse and keyboard. The method of 'tour into the picture' is a simple technique which converts an 2D image into 3D animation. This study shows how to convert 2D image into 3D navigation, implementing the method previously proposed by Horry and Pho on the personal computer. hand-shape gesture recognition which function is as a user interface has been developed into three types : Type-1 means pause: Type-2 means showing directions on 2D : Type-3 is designed to assign upper and lower depth in space. These three types play the role as virtual mouse and keyboard in 3D-rendering image. Above all, using hand-shaped gestures contributes to the ease of user's navigation of 3D space.

Imagery, called visualization, mental practice, mental rehearsal is a technique that has gained considerable attention in sports and dance in recent years because it is thought to enhance skill performance. In this study, theoretical interpretations of the imagery process and factors influencing imagery are reviewed for further study of imagery. The mechanisms that mediate cognition, imagery and motor movement remain mostly unknown. To gain more academic respect, the research on imagery must use better methodologies and attempt theorizing.

Since the oral cavity is directly connected to the outside, it is an important site for microbial invasion, and since it is an environment that is nutritionally and physiologically easy to multiply bacteria, many bacteria always form bacteriological flora in the oral cavity. And propolis is a natural treatment used in many health food stores in various forms for local treatment. This study analyzes the changes in the activity of five oral microorganisms before and after consumption of propolis for various age groups to find out how propolis, which shows the efficacy of anti-inflammatory, antibacterial, and immune sensitization, affects oral microorganisms. Five types of bacteria possessed by periodontal disease patients were specified and digitized targeting the public person, and then before and after propolis intake was compared, and the levels of periodontal disease bacteria in the intake group and the non-consumption group were compared. As a result of comparing the patterns before ingestion (0 week) and after ingestion (3 week) in the oral bacteria analysis, it was confirmed that the bacteria decreased overall except for the five populations in the propolis intake group. In contrast, in the comparative group that did not intake propolis, the bacteria of five periodontal disease increased except for the four populations. What can be seen from this result is that propolis is effective in reducing bacteria in five types of periodontal disease. In order to use propolis as a food for preventing periodontal disease and to get a better effect, further research is needed to find out the mechanism of antibacterial action in propolis compounds.

To study the prevalence of common dermatoses 37,638 and 30,286 new outpatients who visited dermatology clinic with Hanyang University Hospital from January 1981 to December 1985 and from January 1986 to December 1990, respectively. Among the 37,638 outpatients in the first 5 years, the total number of male patients were 18,107(48.1%) and female patients were 19,531 (51.9%). Among the 30286 outpatients in the last 5 years, the total number of male patients were 14,705 (48.6%) and female patients were 15,581 (51.4%). In the both periods, the most frequent age groups was 21-30 (27.3%,25.2% respectively). The 15 common dermatoses, bacterial infection, seborreic dermatitis, drug eruption, verruca, syphilis, psoriasis, herpes zoster, and hypopigmentary disorder, in order of frequency. In thelast 5years, dermatophytosis, contact dermatitis, urticaria, acne, other eczema, atopic dermatitis, seborrheic dermatitis, bacterial infection, drug eruption, verruca, gerpes zoster, psoriasis, hypopigmentary disorder, scabies and syphilis were the 15 common dermatoses, as frequency. In both periods, the dermatosis which showed annually increasing tendency was dermatophytosis and those of decreasing tendency was bacterial infection. In the both periods, dermatophytosis, urticaria, bacterial infection, seborrheic dermatitis, verruca, and hypopigmentary disorder occurred most frequently during the summer season, and the incidence of other ecxema, scabies, atopic dermatitis, and herpes zoster increased during the winter season.

Owing to frequent heavy rain due to abnormal weather, the occurrence of pepper anthracnose has recently increased, which affects the supply and demand of pepper. As a result, the price of red pepper powder in 2011, for example, increased three times compared to the average year. Although anthracnose of pepper plants has been controlled by fungicides until now, it is important to develop new resistant cultivars because of the reduction of the labor force in rural area and occurrence of new anthracnose strains resistant to fungicides. National Institute of Horticultural and Herbal Science developed two pepper lines, ‘Wonye 100005’ and ‘Wonye 100006’ that are resistant to pepper anthracnose. These lines were developed by continuous selection of progenies from a cross between ‘Wonye AR1’, which were developed from interspecific hybridization and ‘TF68’. The anthracnose resistance level of the two lines was higher than that of commercial cultivars and similar to check varieties showing highest level of anthracnose resistance.

A learner can receive various kinds of sensory information, extrinsic feedback about errors from the instructor is one the most critical aspects of the learning environment. This kind of information can have several simultaneous roles ; It can serve as an energizer to increase motivation ; it can reinforce the probability of various future choices ; it can provide information, where it signals the nature and direction of errors and how to correct them ; and it can a learner dependency, where performance suffers when the information is withdraw. Feedback can take on many forms, such as videotape replays, films, and verbal descriptions. The largest errors can be corrected in early learning with frequent feedback. After a few trials, however, learning is best if feedback frequency is gradually reduced across practice.

Imagery, called visualization, mental practice, mental rehearsal is a technique that has gained considerable attention in sports and dance in recent years because it is thought to enhance skill performance. In this study, theoretical interpretations of the imagery process and factors influencing imagery are reviewed for further study of imagery. The mechanisms that mediate cognition, imagery and motor movement remain mostly unknown. To gain more academic respect, the research on imagery must use better methodologies and attempt theorizing. In dance, imagery has been used for communication of movement's meaning, inspiration for creation, exprience of movements's effort. So it is necessary for more efficient dance class to study on cues and sources of imagery which must be sophyscated for levels of ability, kinds of movements and class.
