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.

Statistical Analyses of Interpretive Properties of Korean Multiple Subject Constructions

( Kim Ji-hye ),( Lee Yong-hun ) 한국현대언어학회 2017 언어연구 Vol.32 No.4

Multiple Subject Constructions (MSCs) have been one of the interesting topics in Korean syntax, and there have been lots of studies on this topic. Among the studies, Yoon (2004, 2009, 2015) pointed out that two interpretive properties (Characteristic and Newsworthy) play an important role in making MSCs acceptable to the native speakers. Kim (2015) adopted this idea in her experimental study and showed that these two interpretive properties played a role in Korean native speakers` knowledge of MSCs. This paper applied more statistical analyses to Kim`s (2015) study and investigated how these two interpretive properties affected the acceptability of MSCs. We first adopted a multinomial regression test to examine (i) how these two interpretive properties affected the acceptability of MSCs and (ii) if there is any interaction between these two factors. Then, we applied the predict() function and correlation tests to statistically examine which factor was more powerful. Through the analysis, the following facts were observed: (i) both Characteristic and Newsworthy play a role independently, (ii) there is no interaction between these two factors, and (iii) Newsworthy finally had more powerful influence than Characteristic in the acceptability of MSCs.

Background: Woori-Heukdon (KWH) is a Korean synthetic pig breed generated using Chookjin-Duroc (KCD), Chookjin-Chamdon (KCC), and their crossbreds. Currently, there is a severe lack of studies investigating the Korean breed populations including wild boars (KWB) throughout the genome. Objective: This study was performed to investigate the genetic characteristics of Korean pig populations at the genome-wide level. Methods: Using the SNP dataset derived from genotyped and downloaded datasets using the Illumina PorcineSNP60K BeadChip, we compared the genomes of 532 individuals derived from 23 pig breeds to assess the genetic diversity, inbreeding coefficient, genetic differentiation, and population structure. Results: KWB showed the lowest average expected heterozygosity (HE = 0.1904), while KWH showed the highest genetic diversity (HE = 0.02859) among Korean populations. We verified that the genetic composition of KWH, showing USD of 74.8% and KCC of 25.2% in ADMIXTURE analysis. In population structure analyses, KCC was consistently shown to be separated from other pig populations. In addition, we observed gene flow from Western pigs to a part of Chinese populations. Conclusion: This study showed that Korean native pigs, KCC have genetic differences in comparison with Chinese and Western pigs; despite some historical records and recent genetic studies, we could not find any clear evidence that KCC was significantly influenced by Chinese or Western breeds in this study. We also verified the theoretical genomic composition of KWH at the molecular level in structure analyses. To our knowledge, this is the first genomic study to investigate the genomic characteristics of KWH and KCC.

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

본 연구는 음식물류 폐기물 공공 자원화 시설 운영의 문제점과 제도 개선방안을 위하여 실시하였다. 기존 음식물류 폐기물 공공자원화 시설에 대한 실태조사를 통해 운영에 따른 문제를 분석하였으며, 이를 위하여 음식물류 폐기물의 발생량 및 자원화 현황, 공공 및 민간 자원화시설 현황, 전국의 주요 음식물류 폐기물 공공자원화 시설의 실제 운영과정에서 나타난 문제점을 분석한 결과는 다음과 같다: 현재 국내 음식물류 폐기물의 분리 수거량은 약 97%인 것으로 나타났다. 그리고 대부분의 공공 자원화시설은 음식물류 폐기물의 자원화가 아닌 단순처리에 급급한 것으로 나타났으며 경제성도 없는 것으로 분석되었다. 특히, 바이오가스시설 대부분은 실시설계와는 달리 가스 생산량 및 수요량이 전혀 맞지 않는 것으로 나타났다. This study is conducted to find out problems of the public food waste recycling facility and its improvement. Through a research on the actual condition, it is possible to analyze the problem of operation. Moreover, for this improvement, with analysis of the current state of recycling rate including its generation and the problem that can be shown from the real operation of the public/private food waste recycling facility, the results are as follows: It can be shown that the current amount of domestic food waste resource recycling is about 97 %. Almost every public recycling facility is analyzed to be economically infeasible and is not for recovery but to simple disposal. Especially, most of Biogas facilities appeared that amount of production and demand is not appropriate differed from enforcement design.

光의 照射에 의한 콩나물의 質的變化를 調査할 目的으로 光度 및 光質別 處理를 하여 成長狀態, Vitamin C, chlorphnyll, cellulose등의 含量과 質感에 對한 官能檢査를 行하였으며 chlorophyll과 vitamin C의 關係를 chloramphenicol 處理에 의하여 調査해 보았다. 그 結果 白色光의 경우 50 lux와 100 lux 處理로 vitamin C의 含量 增加와 cellulose등의 生成이 促進되었으며 質感이 暗所보다 良好하였다. 그러나 200 lux 하에서는 매우 不良하였다. blue光은 他光보다 cellulose와 vitamin C生成에 效果的 이었다. chlorophyll과 vitamin C의 含量과는 直接的인 關係가 없고 다만 光照射와의 關聯性이 있는 것으로 推定되었다. This study was carried out to evaluate the quality of green soybean sprouts grown under light. The soybean was germinated under light through blue, red and white polyethylene films at 25℃ for 10 hours a day, and light intensity was controlled 50 to 200 lux. The contents of Vitamin C. cellulose and chlorophyll were determined and checked up texture by sensory evaluation of the soybean sprouts soup. In addition, the relationship of chlorophyll and Vitamin C was measured by treatment of chloramphenicol which has inhibitory effect of chloroplast, chlorophyll accumulating site. Vitamin C and cellulose contents were all increased by irradiation of white light at 50 and 100 lux and also texture of the sprouts was better than it of the sprouts grown under darkness while, it was very tough under 200 lux. Blue light was more effective for biosynthesis of Vitamin C and cellulose than white and reg light. Biosynthesis of chlorophyll was not relative to Vitamin C content directly. but the relationship may be concerned with light irradiation.

국내에서 채집한 진드기에서 중합효소연쇄반응을 이용한 라임병균 및 Ehrlichiosis 원인체의 검출

국내에서 채집한 진드기의 라임병 및 ehrlichiosis원인체 보균 상태를 조사하기 위하여 총 516마리 (Ixodes spp. 22마리, Haemaphysalis spp. 494마리)의 ixodid 진드기를 봄과 가을에 걸쳐 강원도 고산지대 일원에서 채집하였다. 수집한 진드기에서 DNA를 추출 ·정제한 후 추출한 DNA를 template로 이용하여 , Borrelia burgdorferi sensu lato 및 Ehrlichia spp.에 특이하게 반응하도록 제작한 primer를 이용한 중합효소연쇄반응 (polymerase chain reaction, PCR)을 실시하였으며, 이 결과를 oligonucleotide probe를 사용한 southern blotting을 통하여 다시 확인하였다. 총 516마리의 진드기중 B.garinii sensu lato DNA 양성 인 진드기는 68(13.2%)마리 (B. burgdorferi sensu stricto,2; B. afzelii,1; B. garinii,33; B.tanukii,8; B.turdae, 4)로 나타났으며 이 중 37 (7.2%)마리의 진드기 는 southern blot analysis에서도 양성으로 확인되었다. 또한 101 (19.2%)마리의 진드기가 Ehrlichia spp.에 대한 PCR에서 양성 이었으나, 이들 중 25 (4.8%)마리 만이 southern blot analysis에서 양성으로 확인되었다. 그러나 사람의 병인체로 추정 되는 human granulocytic ehrlichiosis (HGE) agent DNA를 보균한 진드기는 확인되지 않았다. 한편 라임병균과 ehrlichiosis원인체를 동시에 보균한 것으로 밝혀진 진드기가 3마리에서 (0.6%)확인되어,국내에서도 진드기 교상시 이들 두 가지 열성질환이 동시에 감염될 가능성이 있는 것으로 사료됨으로 진드기 매개성 열성질환에 대한 적절한 진단법 등을 보다 체계적으로 연구하여야 할 것으로 판단된다. To investigate the distribution of Borrelia Burgdorferi and human granulocytic ehrlichiosis(HGE) agent in ticks, adult ixodid ticks of Ixodes spp. and Haemaphysalis spp. were collected from the high mountain areas of Kangwon Province. Using DNAs extracted and purified in the collected ticks, polymerase chain reaction (PCR) was performed to amplify the specific nucleotide sequences of both agents. Of the 516 ticks, a total of 68 (13.2%) ticks was positive for Borrelia burgdorferi sensu lato with PCR analysis (2 for B. burgdorferi sensu stricto; 1 for B. afzelii; 33 for B. garinii; 8 for B.tanukii; 4 for B. turdae). However a little more than half of PCR-positive ticks (37/68) was found to be positive in the southern blot analysis with Bl6S oligonucleotide probe. One hundred and one (19.2%) ticks were positive for Ehrlichia spp. in PCR, and a quarter of them (25/101) was positive in southern blot with E16S oligonucleotide probe. But none of them was found to be the DNA of HGE agent. And 0.6% (3/516) ticks were positive for both of B. burgdorferi sensu lato and Ehrlichia spp. These findings might implicate the possibility of the outbreak of lyme borreliosis and ehrlichiosis in Korea, and more extensive studies may be need for the diagnosis of multiple tick-borne diseases.

직교분해의 최신화 방법

김부용,이혜영 숙명여자대학교 자연과학연구소 1999 자연과학논문집 Vol.- No.10

직교분해는 통계계산 분야에서 많이 사용되는 유용한 도구중의 하나인데, 각종 통계계산의 정확성과 수치안정성의 측면에서 효용성을 가지고 있다 그러나 직교분해에는 많은 분량의 계산이 요구되기 때문에 계산효율성의 향상을 위한 방안이 강구되어야 한다. 본 논문에서는 직교분해를 반복하여 실행하지 않고 전단계의 계산결과를 바탕으로 직교분해를 최신화하는 방법에 관하여 연구하였다. 한편, 최신화 방법들의 효율성을 측정하였으며 통계계산에의 응용 사례를 제시하였다. The orthogonal decomposition which is also called QR decomposition is frequently applied to the statistical computations since it maintains the numerical stability and accuracy. There are situations where computations have to be performed sequentially as variables or observations are added to or deleted from the data set. In these cases a large amount of computation is required if we compute the statistics repeatedly from the beginning. Thus, we propose the updating techniques of orthogonal decomposition and verify the computational efficiency of the proposed techniques. In addition, applications of the updating techniques to the statistical computings are suggested.
