Moon, Sung-Hwan,Kim, Seong-Oh,Yu, Hyung-Seong,Choi, Byung-Jai,Choi, Hyung-Jun,Lee, Jae-Ho 大韓小兒齒科學會 2006 大韓小兒齒科學會誌 Vol.33 No.2

이번 연구의 목적은 혼합치열기 아동에서 미맹출된 견치와 소구치의 크기를 예측하는데 있어서 한국인에 맞는 방정식을 만들기 위함이다. 미맹출 치아의 크기를 예측하는 것은 혼합치열기 교정 진단과 치료계획 수립에 있어서 매우 중요하다. 미맹출된 견치와 소구치 크기를 예측하는 방법은 몇가지가 있지만 그중에서도 가장 흔하게 쓰이는 것이 모이어의 예측표와 다나카와 존스턴의 방정식이 있다. 하지만 그것들은 백인을 위해서 제작된 것이고 치아 크기는 인종에 따라서 다르다고 알려져 있다. 이번 연구에서는 치아크기를 측정하여 하악 영구 절치의 크기 합과 견치 및 소구치의 크기 합 사이의 상관관계를 구하고 회귀방정식을 이용해서 한국인에 맞는 예측표를 만들었다. 연세대학교 치과대학에 재학중인 178명의 한국 학생(남 108명, 여 70명, 평균연령 21.63)을 대상으로 실험하였다. 영구치의 근원심 폭경을 석고모형상에서 calipers를 이용해서 측정하였다. 성별간의 치아 크기는 차이가 있었다(p<0.05). Correlation coefficient는 0.57에서 0.64의 범위였고, standard errors of the estimates 는 여성에서 0.6으로써 남성보다 우수하였다. r^(2)값은 0.27에서 0.41의 범위를 나타내었다. Estimating the size of unerupted teeth is an essential aspect of orthodontic diagnosis and treatment planning in the mixed dentition. Several methods were introduced and used for the prediction. The most common methods among these would be Moyers probability chart and Tanaka and Johnston equations. These are currently used widely, but they were developed for Caucasians. Because there are clear racial differences in teeth size, the objectives of this study were to produce correlation coefficients between the combined mesiodistal widths of the permanent mandibular incisors and those of the canines and premolars for each quadrant, and prediction tables with regression equations, specifically for Korean. 178 young adults (70 women, 108 men, mean age 21.63 years) were selected from the College of Dentistry, Yonsei University, Seoul, Korea. The mesiodistal crown diameters of the permanent teeth were measured with calipers. Significant sexual dimorphism was found in tooth sizes. The correlation coefficients between the total mesiodistal width of the mandibular permanent incisors and those of the maxillary and mandibular canines and premolars were found to be between 0.52 and 0.64. The standard error of the estimatation was better (0.60) for women and the r^(2) values ranged from 0.27 to 0.41 for both sexes, Prediction tables were prepared for Korean. This study showed larger canine and premolar diameters than Tanaka and Johnston's and Moyers' studies which might be due to the racial differences. Further investigations with a larger sample size will be needed for more representative data on the Korean population.

Performance of electrochemical double layer capacitors using highly porous activated carbons prepared from beer lees

Sang Guk Lee,Hee Moon,Kwang Hyun Park,심왕근,M.S. balathanigaimani 한국공업화학회 2011 Journal of Industrial and Engineering Chemistry Vol.17 No.3

Beer lees precursor is chosen to prepare activated carbons having different physical and chemical properties. The beer lees-based activated carbons (BL-ACs) are characterized by N2 adsorption/desorption isotherms, adsorption energy distributions (AEDs), and X-ray photoelectric spectroscopy (XPS). Furthermore the electrochemical properties of the BL-ACs are assessed using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and constant current charge/discharge method. The maximum specific capacitance (about 188 F/g at discharge current of l mA/cm2) is obtained in 0.1 M H2SO4 electrolyte solution, which is a relatively low electrolyte concentration. The overall results suggest that the BL-ACs are good candidates for EDLC electrode materials.

≪매일신보≫에 연재된 이해조 산정 <강상련>의 특징과 의미

이문성 ( Moon Sung Lee ) 판소리학회 2011 판소리연구 Vol.32 No.-

<강상련(江上蓮)>은 1912년 3월 17일부터 4월 26일까지 총 33회에 걸쳐서 ≪매일신보(每日申報)≫에 연재된다. 이것은 창자 심정순(沈正淳 ; 1873~1937년)의 판소리 <심청가>를 이해조(李海朝 ; 1869~1927년)가 산정(刪正)한 작품이다. ≪매일신보≫에 연재된 이해조 산정 <강상련>의 특징과 그 의미를 살펴보면 다음과 같다. ``강상련``의 표제는 ``강상(綱常)의 도인 효를 실천하고자 목숨을 걸고 물에 빠졌다가 물 밖[江上]으로 살아 돌아온 심청``을 ``연꽃[蓮]``에 비유하여 명명한 이해조의 재치로 여겨진다. 신문 연재본 <강상련>에서 심봉사 안맹과 곽씨부인 죽음의 시점은 심청의 고난의 정도를 극대화한 설정이다. 이것은 극한의 역경에도 불구하고 출천대효로서 역할을 다하는 심청을 부각시킨다. 또한 심청과 심봉사의 연령을 나타내는 표지는 인물의 고난기간과 보상기간을 맞추고 있는 듯하다. 심봉사는 ``칠십 향수``, 일평생인 70세를 기준으로써 잃어버린 딸을 되찾고 잃어버린 시력을 되찾고 새 처자를 만나서 새 자식들과 새 가정을 갖게 된다. 심청은 인당수의 제수가 될 때까지 고단했던 15년의 삶을 용궁생활과 황궁생활의 ``15~16년``으로 보상받는다. 신문 연재본 <강상련>은 활자본에 비해서 선본(先本)일 뿐만 아니라, 문면이 정제된 선본(善本)으로서의 가치가 높다. 또한 신문 연재본 <강상련>은 판소리 장단 표지를 중심으로 사설을 담고 있어 소설뿐만 아니라, 판소리 예술 자료적 가치를 지닌다. 아울러 신문 연재본 <강상련>을 비롯한 일련의 판소리 산정 작품은 이해조의 식자로서의 면모와 수완을 이해하는 데에, 20세기 초 신문·출판문화를 이해하는 데에 기초자료가 될 만하다. 이에 신문 연재본에 대한 적극적인 고구가 필요할 듯하다. This article is a study on <Kangsanlyeon> published on ≪Maeil Shinbo≫ which is one of korean daily newspapers in the early 20th century. <Kangsanlyeon> is based on <Shimcheong-ga> which is sung by Sim, Jeongsun who is a famous vocalist of pansori and recreated by Lee, HaeJo. <Kangsanlyeon> published on ≪Maeil Shinbo≫ becomes a model of other pieces of novels, Kangsanlyeon and Simcheongjeon. <Kangsanlyeon> contains a lot of symbols that present filial piety and interest elements to readers. It is the first and the best work of Kangsanlyeon`s and Simcheongjeon`s since 1912. <Kangsanlyeon> published on ≪Maeil Shinbo≫ has various pansori modes of singing. It has the value of a musical text in the history of pansori because a sound and melody of <Shimcheong-ga> which was sung by Sim, Jeongsun has disappeared already. Through <Kangsanlyeon>, we can understand an ability of Lee, Haejo as a writer and recreator, the best model of Kangsanlyeon`s and an aspect of publishing culture in the early 20th century.

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.

지역보건의료계획 수립에 있어 지역의료보험자료의 활용가능성

이상이,김철웅,문옥륜,Lee, Sang-Yi,Kim, Chul-Woung,Moon, Ok-Ryun 대한예방의학회 1997 예방의학회지 Vol.30 No.4

The health center has to play an important role in promoting community health and satisfying a variety of community health needs and demands in the decentralized Korea. The nearly enacted Community Health Act compels every health center to make its own health plans which intend to deal with local health problems and plan its future health care. This obligation is obviously a big burden to most health centers. They do not have experiences in and abilities of making local health care plans. In order to establish a systematic community health plan, health centers have to concentrate their efforts on enhancing the ability of making health care plan through gathering and analysing the local health informations. However, it is very difficult in reality. This is simply because it will take long time to accomplish these activities. It seems natural that various professionals and researchers participate in carrying out the process of making community health plan in the initial stage. No standardized methodology and analysing framework exist even in the health professional society. Nonetheless, it is common to introduce survey research methodologies in analysing consumer's health care utilization and cost, and in identifying factors influencing health behaviors. Many researchers and professionals have applied social survey methodologies in obtaining information on providers and health policy makers as well. The authors have found that few studies have ever utilized local health data stored at the self-employed medical insurance society as the data source of planning activities. The purpose of this study is to illustrate the usefulness of the data stored at the Sung-Dong Gu Self-employed Medical Insurance Society in establishing the community health plan. The major contents of this study are as follows ; 1. frequency of utilization by age, area, sex, type of medical care institutions, and some major diseases 2. Medical treatment by type of medical care institutions, by classification of 21 diseases, by frequency of three-character categories 3. Medical treatment of major neoplasm and some chronic diseases by age, sex, and area. The conclusion of this study is that it is of great potentiality to find out the local health problems and to use them in blueprinting the community health plan through comparing the frequency of medical utilization analyzed by a variety of variables with NHI health data or the health data from survey research.

본 연구에서는 배의 유용성 증명을 위한 일환으로 배의 화학성분을 분자수준에서 밝히고자 하였다. 이에 배 과피 MeOH 추출물을 용매분획하여 얻은 EtOAc-산성 분획과 EtOAc-중성분획을 대상으로 Sephadex LH-20, silica gel, 그리고 ODS colmn chromatography와 HPLC를 이용하여 정제 및 단리하였다. 그 결과, EtOAc-산성 분획과 EtOAc-중성 분획으로부터 각각 2종씩의 화합물을 단리하였다. 단리된 화합물 1-4는 1H- 및 13C-NMR 분석을 통하여 각각 (S)-(+)-2-cis-abscisic acid O-β-D-glucopyranosyl ester (화합물 1), 1-[4-O-β-D-glucopyranosyl]phenyl ethanone(piceoside, 화합물 2), β-sitosterol (화합물 3), 그리고 β-sitosteryl 3-O-β-D-glucopyranoside (화합물 4)로 동정되었다. 단리된 3종의 배당체 화합물(화합물 1, 2, 4)들은 본 연구에 의해 배로부터 처음 동정되었으며, 화합물 3은 추황배로부터 처음 동정되었다. 본 연구결과가 배 함유 성분연구는 물론 배의 기능성 해명 연구에도 추후 중요한 기초자료로 활용되길 기대한다. We isolated and identified antioxidants from acidic and neutral ethyl acetate fractions of the peel of pear (Pyrus pyrifolia N. cv. Chuhwangbae). We isolated 4 compounds from the methanol extract, by using 3 different types of column chromatography (Sephadex LH-20, silica gel, and octadecylsilane) and preparative HPLC. We identified the isolated compounds as (S)-(+)-2-cis-abscisic acid O-β-D-glucopyranosyl ester (compound 1), 1-[4-O-β-D-glucopyranosyl]phenyl ethanone (picroside, compound 2), β-sitosterol (compound 3), and β-sitosteryl 3-O-β-D-glucopyranoside (compound 4) by nuclear magnetic resonance analysis. We are the first to report the identification of compounds 1, 2, and 4 from pear.

Park, Nam Suk,Lee, Sang Mong,Moon, Jae Yu,Seong, Su Il 한국잠사학회 1999 한국잠사곤충학회지 Vol.41 No.2

The storage protein-like protein has been purified from the 5th instar larval haemolymph of the Chinese oak silkworm, Antheraea pernyi, and the preparation was shown to be homogeneous by 7.5% nativePAGE. The molecule was consisted of a single Submit with a molecular weight of 80K, but the number of the subunits was not determined. The protein was defined as glycoprotein by Schiffl's reagent stainting. Rabbit antibody prepared against the purified protein crossreacted with the 5th instar larval haemolymph protein of Antheraea pernyi and Anteraea yamamai, but not with those of Bombyx mori and Bombyx mandarina.

A Case of Hyperglycemic Hyperosmolar State Associated with Graves' Hyperthyroidism: A Case Report

Moon, Sung Won,Hahm, Jong Ryeal,Lee, Gyeong-Won,Kang, Mi Yeon,Jung, Jung Hwa,Jung, Tae Sik,Lee, Kang Wan,Jung, Kyoung Ah,Ahn, Yong Jun,Kim, Sunjoo,Kim, Me Ae,Kim, Deok Ryong,Chung, Soon Il,Park, Myoun The Korean Academy of Medical Sciences 2006 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.21 No.4

<P>Hyperglycemic hyperosmolar state (HHS) is an acute complication mostly occurring in elderly type 2 diabetes mellitus (DM). Thyrotoxicosis causes dramatic increase of glycogen degradation and/or gluconeogenesis and enhances breakdown of triglycerides. Thus, in general, it augments glucose intolerance in diabetic patients. A 23-yr-old female patient with Graves' disease and type 2 DM, complying with methimazole and insulin injection, had symptoms of nausea, polyuria and generalized weakness. Her serum glucose and osmolarity were 32.7 mM/L, and 321 mosm/kg, respectively. Thyroid function tests revealed that she had more aggravated hyperthyroid status; 0.01 mU/L TSH and 2.78 pM/L free T3 (reference range, 0.17-4.05, 0.31-0.62, respectively) than when she was discharged two weeks before (0.12 mU/L TSH and 1.41 pM/L free T3). Being diagnosed as HHS and refractory Graves' hyperthyroidism, she was treated successfully with intravenous fluids, insulin and high doses of methimazole (90 mg daily). Here, we described the case of a woman with Graves' disease and type 2 DM developing to HHS.</P>
