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.

고속도로 IC 및 JCT 주변 유휴부지의 물류시설 활용가능성 분석 : 수도권 및 지방광역시를 중심으로

양현지(Yang, Hyun-Ji),최재성(Choi, Jae-Sung) 한국물류학회 2021 물류학회지 Vol.31 No.2

최근 코로나 19 등의 감염병으로 인한 비대면 활동 증가로 인터넷, 모바일 등을 통한 이커머스 택배 이용건수가 증가하며 택배업체 등의 물류시설 부지 확보 수요가 점점 증가하는 추세이다. 업체별로 필요한 부지를 연도별 임계치 수준에서 수급하며 적게는1천 평에서 많게는 1만 평 이상의 부지가 추가적으로 필요하므로 부족한 부지를 현재와 같이 부동산업체 등을 통해 사적영역에서확보하는 것은 지속가능성의 한계에 직면할 것으로 보인다. 본 연구에서는 수도권(서울, 인천, 경기도) 및 지방광역시(대전, 대구, 광주, 울산, 부산)를 중심으로 공공 부문의 도시계획시설 측면에서 가장 넓은 유휴부지의 확보가 가능한 고속도로 IC/JCT 교통광장 유휴부지의 부지현황⋅활용가능성을 분석하였다. 분석방법 및 내용으로 다음 카카오맵의 로드뷰, 스카이뷰 등을 활용해 연구대상지의 유휴부지를 전수조사 후 사업지 내 이면도로 등의 존재 유무에 따라 단기 및 중⋅장기적 사업 우선순위화 분류, 국가물류통합정보센터 내 물류단지 건립계획을 이용해 택배업체의 허브 및 서브터미널 건설 시 예상 사업비 분석, 한국은행의 산업연관표를 적용해 경제적 파급효과 등의 결과를 도출하였다. 도출된 유휴부지를 택배업체 등에서 활용하기 위해서는 IC/JCT 교통광장대부분의 지역이 현재 ｢국토계획법 시행령 제71조｣에 의해 생산⋅자연녹지 용도지역인 상황을 고려하면 ｢건축법 시행령 별표1｣ 의 ‘18.창고시설 중 물류터미널’을 추가하는 방안, ｢도로법｣내 교통광장의 설치 및 관리에 관한 규정을 신설하거나 박성중 의원등 10인이 제안하여 위원회 심사 중인 ｢도로공간의 입체개발에 관한 법률안｣의 본회의 통과를 통한 입법화를 완료해 법적 근거마련이 필요한 상황으로 보인다. 향후 법제도 개선을 통해 고속도로 IC/JCT의 유휴부지(총 183만평-수도권 140만평, 지방광역시43만평) 중 수도권은 약 12%, 지방광역시는 약 10% 정도만이라도 활용 가능하다면‘19년 한국통합물류협회의 18개 택배사업자가제시한 물류시설 구축을 위한 유휴부지 마련 수요를 충족시켜 부지확보의 어려움이 일정 부분 해소될 수 있을 것으로 추정한다. As contact-free activities have increased due to infectious diseases such as COVID-19, the number of delivery-related services has also increased through the rise of e-commerce. As such, the demand for securing sites for logistics facilities is rising as well. Each delivery company keeps supply and demand in balance at the annual threshold level, which means that they require additional land ranging from 3,300m2 (1,000 pyeong) to as much as 33,000m2 (10,000 pyeong). However, it is unreasonable to continuously secure land to meet demands from private areas through real estate companies, as is the current standard procedure done by delivery companies. This study analyzes the feasibility of securing unused land in its current state, focusing on unused sites in expressways IC/JCT, where the widest unused land, in terms of urban planning facilities can be found, mainly in the capital region (Seoul, Incheon, Gyeonggi-do) and provincial metropolitan cities (Daejeon, Daegu, Gwangju, Ulsan, Busan). Full-scale inspection of unused land near expressways is first conducted using Kakao Map’s Road View and Sky View, and the results, such as short-term or mid to long term business priorities, are derived depending on whether backside roads exist or not. Estimated business expenses are calculated using information of logistics center from the National Logistics Integrated Information Center, and economic effects of building hubs and sub-terminals for delivery companies in the unused land are also drawn, applying the Leontief input-output table from the Bank of Korea. Most unused land such as those surrounding roundabouts near expressways IC/JCT is considered as productive green areas and natural green areas in accordance with Article 71 of ｢Enforcement Decree of the National Land Planning and Utilization Act｣, so clause 18, which states “logistics terminal amongst storage facility field”, of schedule 1 in ｢Enforcement Decree of Building Act｣ should be added to the Article to loosen restriction on construction in areas surrounding roundabouts. Also, regulations on the installation and management of roundabouts in the ｢Road Act｣ should be established to allow delivery company to utilize the unused land derived through this analysis. Preparation of a legal basis is deemed necessary by passing legislation through the plenary session for ｢The Bill on the Development of Three-dimensional Road Space｣ under examination made by 10 lawmakers, including Park Sung-joong. If approximately 12% of the total unused land in expressways IC/JCT in the capital region and approximately 10% in provincial metropolitan cities are made available by improving the legal system in the future, demand of 18 delivery companies from Korea Logistics Association will be met. Through this, it is estimated that the difficulty of securing sites for logistics facility construction would be partially resolved.

Choi Hye-Ji,Yang Chan-Mo,Lee Sang-Yeol,Lee Hye-Jin,Jang Seung-Ho 대한신경정신의학회 2022 PSYCHIATRY INVESTIGATION Vol.19 No.2

Objective The aim of this study was to assess the psychosocial characteristics of the employees working at a university hospital and investigated the factors affecting their quality of life (QOL) under COVID-19.Methods This study enrolled 1,191 healthcare workers from a university hospital, including doctors, nurses, administrative officer and technicians. Besides demographic information, depression, anxiety, somatization, insomnia, resilience, and QOL were assessed.Results The nurses presented significantly higher scores for anxiety, depression and showed significantly higher insomnia scores and significantly lower resilience scores. The occupations showed significant differences in the QOL and sub-groups, including the overall quality of life and general health (F=4.774, p<0.001), psychological domain (F=6.230, p<0.001), and environment domain (F=5.254, p<0.001). There was a positive correlation between the QOL and resilience (r=0.608, p<0.01). However, depression (r=-0.502, p<0.01), anxiety (r=-0.425, p<0.01), somatization (r=-0.364, p<0.01), and insomnia (r=-0.385, p<0.01) showed negative correlations with the QOL. Resilience was the most important factor influencing the QOL.Conclusion The results of this study showed that low resilience adversely affected the QOL and the mental health of the healthcare workers, which consequently had a direct effect on the quality of medical care given to patients.

DEVELOPMENT OF AN OPERABILITY EVALUATION FRAMEWORK FOR REMOTELY CONTROLLED GROUND COMBAT VEHICLES IN A SIMULATED ENVIRONMENT

Ji Hyun Yang,Sang Yeong Choi,Kang Park 한국자동차공학회 2018 International journal of automotive technology Vol.19 No.5

This paper proposes a systematic framework for operability evaluation of remotely controlled ground combat systems (RGCS) in a simulated environment. The popular human-robot interaction metric used in unmanned vehicle systems is called fan-out (FO) and represents the maximum number of robots/vehicles that could be controlled by a single human operator. However, FO is inappropriate for systems with a lower level of automation where vehicles are remotely controlled by a human, such as RGCS. The theoretical background of the suggested framework is based on McRuer’s crossover model that was initially developed in the aviation domain for explaining pilot handling issues. In this study, an evaluation/analysis software prototype was developed, known as the RGCS operability evaluation tool in a simulated environment (ROPES). The ROPES was designed to be a simple tool for use by officers or researchers who only have intuitive understanding on the human adaptability. The ROPES includes two sub-modules; 1) an interactive interface for the configuration of the RGCS dynamic parameters and user interfaces and 2) a time-varying graphical display of system and human performance. Examples case studies demonstrate the advantage of the ROPES, and improvement points were identified for future development.

Most forage crops growing under field conditions are often being exposed to various environmental stresses such as drought, freezing, high temperature, waterlogging and climate change. A combination of grass breeding approaches will likely be needed to improve significantly the environmental stresses tolerance of forage crops in the field. Attempts have been taken by grass breeders to develop tolerant varieties of different crops for environmental stress. A new tall fescue variety (Festuca arundinacea Schreb.) named ‘Purumi’ was developed by the National Institute of Animal Science, Rural Development Administration from 1999 to 2007. For synthetic seed production of this new variety, 5 superior clones, EFa9108, EFa0010, EFa0020, EFa0108, and EFa0202 were selected and polycrossed. The agronomic growth characteristics and forage production capability of the seeds were studied at Cheonan from 2004 to 2005, and regional trials were conducted in Cheonan, Pyungchang, Jeju, and Jinju from 2008 to 2010. ‘Purumi’ showed enhanced winter hardiness, disease resistance, and regrowth ability as compared to ‘Fawn’. The dry matter yield of ‘Purumi’ was about 5.6% higher as 16,821kg/ha than that of ‘Fawn’. However, the nutritive value of both varieties was similar. When this new variety of tall fescue, Purumi, has been developed and distributed with its most remarkable adaptability for Korean climates and superior value as a livestock feed, it is expected to play an important role for a new restoration of the pasture industry in Korea.
