慶尙北道내 肺吸蟲 浸潤地 溪谷에서의 가재의 最近 棲息狀과 가재에서의 폐흡충 피낭유충의 最近 寄生狀을 究明코저 1981年 10月부터 1982年 9月까지 6個處(達城郡 嘉昌面 蛇洞, 玉盆洞, 上院洞과 榮豊郡 豊基邑 錦溪, 英陽郡 英陽面 化川 및 靑松郡 府東面 上宣溪谷)를 調査對象溪谷으로 選定하여 調査한 後 1974年 朴 및 崔의 調査 成績과 比較하였다. 6個處의 肺吸蟲 浸潤地에서의 가재의 棲息密度는 1974年의 그 密度에 比하여 顯著히 低下되었으며 가재에서의 폐흡충 피낭유충의 寄生率과 그 寄生程度도 1974年의 成績에 比하여 낮았다. 가재의 體部位別 폐흡충 피낭유충의 寄生狀에 있어서는 1974年에는 가재의 全體部位에서 本피낭유충을 찾아 볼 수 있었는데 比하여 이번 調査에서는 가재의 頭胸部, 아가미 및 肝에서만 찾아볼 수 있었으며 가재 한마리當 폐흡충 피낭유충數도 全浸潤地에서 1974年에 比하여 1982年에는 甚히 적었다. 폐흡충 피낭유충이 寄生하는 가재의 數와 이들 가재에서의 本피낭유충의 數가 1982年에는 너무 적으므로 가재의 크기와 本피낭유충數 및 1974年의 調査成績과의 相關을 求할 수 없었다. 이번 調査 結果 1974年에서 1982年까지의 지난 8年間 폐흡충 浸潤地에서 가재의 棲息密度와 폐흡충 피낭유충이 寄生하는 가재의 數가 急激히 減少되었음을 알았다. In an attempt to determine the recent patterns of population density of the crayfish, Cambaroides similis, and infestation of the crayfish with the metacercaria of Paragonimus westermani in Kyungpook Province, Korea, the crayfish collected in the six endemic areas, Kum-ge, Wha-cheon, Sang-seon, Ju-dong, Ok-bun dong, and Sang-weon dong streams were examined from April, 1981 to September, 1982. The results obtained in 1982 were compared with the data derived from the crayfish collected at the same streams by Park and Choi(1974). The population density of crayfish in the six endemic areas of P. westermani in the present study decreased markedly compared with those in 1974. The infestation rate for the metacercaria of P. westermani in the crayfish examined and the intensity of infestation in the positive crayfish also decreased compared with those reported by Park and Choi(1974). In the 1974 survey, the metacercaria was found in all parts of the crayfish whereas it was found only in the cephalothorax, the gills, and the liver in the present suevey. In the average number of metacercariae perpositive crayfish (M.P.P.C), a pronounced reduction was encountered in all endemic areas between 1974 and 1982. The number of infested crayfish and the metacercaria of P. westermani in infested crayfish in 1982 was so small that it was impossible to analyze the relationship between the number of metacercaria and the length of crayfish and to compare the data between 1974 and 1982. It was found in the present study that the population density of crayfish in the endemic areas and the infestation of the crayfish with the metacercaria of P. westermani has decreased drastically over the eight-year period from 1974 to 1982.

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.

입제의 수면처리에 의한 주요수도해충의 동시방제

최승윤,배상희,송유한,Choi Seung Yoon,Bae Sang Hee,Song Yoo Han 한국응용곤충학회 1970 한국식물보호학회지 Vol.9 No.1

본 시험은 유기인계 살충제인 Terracur P입제 및 Lebaycid 입제와 유기염소계 살충제인 상감마입제$(\gamma-BHC 입제)$를 수면시용 하였을때 수도요해충인 이화명충, 끝 동매미충, 애멸구 및 흰둥멸구에 대한 동시방제가능성과 방제적기를 구명하고 약제간의 방제효과를 비교코저 실시하였다. 얻어진 시험결과는 다음과 같다. 1) 약제처리후 부화직후 이화명충 접종 시험에 있어서 상감마와 Terracur P는 높은 살충율을 보였으나 Lebaycid의 살충율은 낮았다. 約 $50\%$ 살충력 잔효일수에 있어서 상감마는 8-14日이었고 Terracur P는 6일간이었다. 2) 당초 계획된 방제적기에 관한 정보는 얻을 수 없었다. 즉 주어진 일간격이 좁아 유의한 차를 얻을 수 없었다. 3) 1,2화기 이화명충에 대한 방제효과는 Terracur P=상감마>Lebaycid의 순이었다. 4) Terracur P와 Lebaycid 입제의 처리는 끝동매미충의 방제효과가 좋았으나 상감마$(\gamma-BHC 입제)$의 방제효과는 기대할 수 없었다. 끝동매미충에 대한 Terracur P와 Lebaycid입제의 잔효력은 30일 이상이었다. 5) 애멸구와 흰등별구에 대한 시험은 충의 서식밀도가 낮기 때문에 약제간 방제효과를 얻을 수 없었다. 6) 공시약제중 Terracur P와 Lebaycidd입제는 이화명충과 끌동매미충의 동시방제제로서 사용할 수 있을 것 같다. This experiment was conducted to find out the simultaneous control effect of granulated insecticides on the several major rice insect pests in Korea. The granulated insecticides used were Terracur P$5\%$ (one of the phosphoric insecticides), Lebaycid $5\%$, and Sang-gamma (gamma-BHC) $6\%$. Those insecticides were broadcasted by hand on the paddy field at the ratio of 3kg. in June and 4kg. in August per 10 a, and the date of insecticidal application was based on the maximum moth occurrence of the rice stem borer in 1969. The rice insect pests tested in this study were rice stem borer (Chilo suppressalis W.), green rice leafhopper (Nephotettix bipunctatus cincticeps U.), smiller brown planthopper (Laodelphax striatellus F.), and white back planthopper (Sogotella furcifera H.). For the study of residual effectiveness of the insecticides, the rice stem borer larvae just hatched from the eggs were installed on the sheath of rice plants collected from the paddy field after insecticidal treatment, and the mortality was made at 48 hours after installation. High mortality was observed in Terracur P and Sang-gamma treatments and low mortality in Lebaycid treatment. The duration of residual effects giving about 50% mortality was about 14 days in Sang-gamma and about 6 days in Terracur P treatments. The study on the effectiveness of the insecticides to the rice stem borer in the paddy field was made by the number of dead blades and white heads of the rice plants injured by the larvae, and the number of survival larvae in the straws after crop harvest. The order of insecticidal effectiveness to the rice stem borer was Terracur P=Sang-gamm>Lebaycid. The study on the effectiveness of the insecticides to the leafhoppers and planthoppers in the paddy field was made by the population density by sweeping (5 times) at the given day intervals after treatments. Terracur P was highly effective for the control of the green rice leafhoppers and Lebaycid was moderately effective, but Sang-gamma seemed not to be effective. The effectiveness of the insecticides tested to the planthoppers was not clear, and it seemed to related with the low insect population density. Study on the determination of proper timing of insecticidal application was not also made clear, and it seemed to be short in the range of day intervals in the insecticidal application. For the study on the control effects of the rice insect pests, rice yield per 100 hills per plot was observed. There was no statistically significant difference among the treatments in rice yields, but the order of yield (Terracur P>Sang-gamma>Lebaycid>Control) was paralleled with the tends of control effects above mentioned. In a view point of simultaneous control of the rice stem borers and green rice leafhoppers by the application of granulated insecticides, Terracur P and Lebaycid were more effective than Sang-gamma which have been used.

최상덕,김호진,라성주,정형택,윤호섭,신종암,이원교 國立 麗水大學校 環境問題硏究所 1999 環境硏究論文集 Vol.2 No.-

The effect of different temperature, salinity and pH on survival rate of Urechis unicinctus's swimming embryo was examined to develop the method for the efficient seed production. In addition to, this study was designed to investigate the possibility of pollutant marker diagnosis of marine pollutions by the change in different temperature, salinity and pH. Treatment was carried out whit different temperature (5˚C, 10˚C, 17˚C, 20˚C, 25˚C,), salinity(0‰, 10‰, 20‰, 30‰, 34‰, 40‰) and pH(4, 6, 7.2, 8.2, 9.2, 10). All the swimming embryo of the temperature experiment was survived within all experiment section, but the others experiment were not. At the temperature-shock and tolerance experiment ranging from 5˚C to 25˚C the survival rate was occurred: 75%, 95%, 100%, 100%, 50%, at the ph-Shock experiment ranging from 4 to 10, the survival rate was occurred: 0%, 50%, 85%, 100%, 60%, 0%, at the pH-tolerance experiment ranging 4 to 10 the survival rate was occurred : 0%, 75% 90%, 100%, 80%, 0%, and at the salinity-shock experiment ranging from 0% to 40% the survival rate was occurred : 0% 10% 90% 95% 100% 0% , at the salinity-tolerance experiment ranging from 0% to 40% , the survival rate was occurred : 0% 0% 90% 100% 100% 0%. These results suggest, that the survival rate of larvae of Urechis unicinctus was the highest at 17˚C, 34%. pH8.2 and this Urechis unicinctus could be live at the zone of euryceious and zone of euryhalines

단일 치근을 가진 하악 제1유구치

윤상일,최형준,김성오,이제호,손흥규 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.4

본 증례에서는 단일 치근을 가진 하악 제1유구치에 대해 서술하고자 한다. 5세 남아의 하악 제1유구치는 방사선 사진 검사결과 양측성으로 분명한 단일치근을 가진 것으로 나타났다. 보통 상악 구치는 3개의 치근을, 하악 구치는 2개의 치근을 가지나, 치아의 발육시기도중 Hertwig상피근초가 제 시기에 적절히 함입되지 못하면 치근이 서로 나뉘지 못하여 치근의 융합이 발생될 수 있다. 융합된 치근을 가진 구치는 정상적인 구치보다 불리한 치관-치근 비율을 가질 뿐 아니라, 여러 보고에 의하면 융합된 치근을 가진 사람은 다수 치아의 선천적 결손이나, 상악 전치에서 치내치가 발현될 확률이 높아 예방적 치과 치료가 필요할 수 있다. 그리고, 외배엽이형성증, 합지증, 만지증, 청색공막증과 같은 전신 질환과 연관되어 나타날 수도 있다고 한다. 치근융합은 유전적으로 상염색체 열성 유전을 따른다고 밝혀진 바 있다. 현재까지 단일 치근을 가진 구치는 대부분 영구 구치에서 많이 보고된 바 있지만, 유구치에서는 거의 보고된 바가 없기에 이에 보고하는 바이다. In this case, we would like to discuss about the single rooted deciduous mandibular first molar. The deciduous mandibular molar of a five years old boy was shown to have a single root, bilaterally. Ordinarily, the maxilary molars have three roots and the mandibular molars have two roots. However, when the hertwig's epithelial root sheath do not invaginate properly during tooth development, root fusion can occur from the absence of root separation. Molars with fused roots not only have unfavorable crown to root ratio, but also according to many reports, have higher probability of having multiple congenitally missing teeth or dens invaginatus in the maxillary incisors, consequently requiring preventive dental treatment. In addition, disorders such as ectodermal dysplasia, syndactyly, clinodactyly, bluish sclera can also be related to this condition. Root fusion is known to be of autosomal recessive inheritance. Up to date, single rooted molars have been reported several times in permanent dentitions but hardly in deciduous dentition, which is the motive for this paper.

Percutaneous vertebroplasty has recently been introduced as a therapeutic alternative for the treatment of pain associated with osteoporotic compression fractures and performed popularly at a few centers by neurosurgeons. This technique allows marked pain relief through stabilization of microfractures and strengthening of weakened vertebral body. Authors retrospectively analyzed the clinical outcome of 100 patients with osteoporotic compression fractures for investigating the therapeutic effectiveness of percutaneous vertebroplasty. They were treated with vertebroplasty from April to August 1999. Plain X-ray of all patients showed osteoporotic compression fractures at more than one level.

제2형 당뇨병 환자에서 QUICKI법을 이용하여 측정한 인슐린 저항성과 비만도와의 관계

성윤경,최웅환,이창범,박용수 대한비만학회 2003 The Korean journal of obesity Vol.12 No.3

연구배경: 인슐린 저항성은 제2형 당뇨병의 중요한 병인으로서 비만과 밀접한 관계가 있으며, 이와 연관된 고지혈증. 고혈압의 발생은 결과적으로 혈관 합병증의 빈도를 높이는 것으로 알려져 있다. 본 연구에서는 한국인 제2형 당뇨병 환자를 대상으로 하여 새로운 인슐린 저항성 평가법인 QUICKI법을 이용하여 인슐린 저항성을 측정하고, 이와 비만도 및 체지방 분포, 지질 등의 대사성 인자들과의 상관 관계를 평가하고자 하였다. 방법: 연구 대상은 2000년 5월부터 2002년 10월까지 한양대학병원 내분비대사내과에서 당뇨병으로 치료 받은 환자 중 인슐린과 경구혈당 강하차를 투여하지 않은 103명을 차상으로 하였으며, 인슐린 저항성은 공복시 측정한 인슬린치와 포도당치를 이용하여 계산하는 QUICKI법을 이용하였다. 비만도는 입원시 키와 몸무게를 통하여 체질량지수를 측정하였으며, 체지방의 정량화와 분포를 알아보기 위하여QDR4500의 DEXA system (Hlologic, USA)을 이용하여 지방량과 건체중. 총 체지방률, 복부 지방률 등을 측정하였다. 측정 결과는 평균, 표준편차, 백분율 등으로 제시하였고 남녀간평균값의 비교 분석은 independent t-test를 시행하였다. 인슐린 저항성과 각 변수들과의 상관 관차는Pearson 상관 차수를 통해 비교하였고, 단계별 다중회귀분석을 통하여 인슐린 저항성에 가장 영향을 미치는 인자를 평가하였다. 이상의 모든 통계 분석은 SPSS (version 11.0)를 사용하였으며, 통계학적 유의 수준은 p값을 0.05 이하로 하였다. 결과: (1) 평균 연령은 55.7±12.8세, HbA_(IC)는 9.9±2.7%로 측정되었고, 체질량지수는 23.8±3.7kg/㎡', QUICKI값은 0.38±0.07로 계산되었다. (2) 남녀간에 체질량지수. EHA_(IC), 연령 등에서는 유의한 차이가 없었던 반면 QUICKI값. 총 체지방량 및 복부 지방량. 총 체지방률과 복부 지방률, 그리고 각각의 지질치에 있어서 유의한 차이가 있었다. (3) QUICKl법으로 측정된 인슐린 저항성은 HDL 콜레스테롤과 양호한 양의 상관 관계(r=0.456, p<0.01)를 보인 반면, 체질량지수(r=0.407, p<0.001), 총 체지방량(r=0.458, p<0.001), 복부 지방량((r=0.475, p<0.001), 총 체지방률(r=0.438, p<.0.01), 복부 지방률(r=0.457, p<0.01) 그리고 건체중과 대비한 총 체지방량(r=0.392, p<0.01)과 복부 지방량(r=0.423, p<0.01)과도 양호한 음의 상관 관계를 보였으며, 총 콜레스테롤(r=0.281, p<0.01), TG (r=0.333, p<0.01), LBL 콜레스테롤(r=0.326, p<0.01)과도 음의 상관 관계를 보였다. 그러나 수축기 및 이완기 혈압, HbA_(IC)와는 유의한 상판 관차를 보이지 않았다. 한편, 이러한 대사성 인자들과 QUICKI값과의 상관 관계의 정도는 HOMA_(IR)값과의 상관 관계에 비해 약간 높은 것으로 나타났다 (4) 단계별 다중회귀분석을 통하여 인슐린 저항성에 가장 영향을 미치는 인자를 분석한 결과 복부 지방률(R²=0.209, p<0.001), HDL 콜레스테롤(R²=0.135, p<0.001), 총 콜레스테롤 (R²=0.056, p<0.01) 등의 기여율이 가장 높은 것으로 나타났다. 결론: 한국인 제2형 당뇨병 환자의 인슐린 저항성을 QUICKI법을 이용하여 측정하였으며, 단순한 체질량지수나 전체 및 복부의 절대적인 지방량 보다는 복부를 구성하는 체성분중 지방이 차지하는 비율인 복부 지방률과 혈중HDL 콜레스테롤 및 총 콜레스테롤 수치가 인슐린 저항성을 가장 잘 설명하는 것으로 나타났다 따라서 이러한 인자들에 대한 개선 노력은 인슐린 저항성의 개선 및 제2형 당뇨병 발현의 억제에 기여할 것으로 판단된다. Background : Insulin resistance plays an important role in the pathophysiology of diabetes and is associated with obesity and cardiovascular disease. The aim of this study was to investigate the relationships between insulin resistance generated by quantitative insulin sensitivity check index(QUICKI) and regional adiposity, body mass index (BMI), and serum lipid profile in Korean type 2 diabetic patients. Method: Study subjects included fat mass and lean body mass by dual energy x-ray absorptiometry(DEXA) system. Insulin resistance was estimated by the QUICKI. Result :50 were women and 53 were men, with a mean (±SD) age of 54.2 years(±12.8). The mean(±SD) score of QUICKI was 0.38(±0.07). Insulin resistance was positively correlated with total body fat percent, abdominal fat percent, BMI, total cholesterol, LDL-cholesterol, and triglyceride, and negatively correlated with the HDL-cholesterol. In multivariate model, the predicting variables on insulin resistance were abdominal fat percent, HDL cholesterol, and total cholesterol. Conclusion: In this study, we observed that the abdominal fat percent, HDL cholesterol and total cholesterol were meaningful variables correlated with insulin resistance among variables. Therefore, to improve insulin sensitivity in Korean type 2 diabetic patients, we should reduce the abdominal fat percent and total cholesterol and increase the level of HDL-cholesterol.

소음·진동에 따른 참전복(Haliotis dissus hannai)의 행동·생태학적 변화

These days, the underwater excavation and the piling work have been commonly used to reclaim land and to build a breakwater. As the piling work generates high underwater sound pressure in all direction, various kinds of marine organisms are largely affected even if they live a long distance from the piling work. Therefore, this paper describes the relationship between the behavior of abalone(Haliotis discus hannai) of 50cm long and the environmental noise level with vibration due to the piling work. We have separated the research into two parts. The one is continuance impact, the other is intermittent impact. The following are the results obtained from the present investigation: Comparing 0.5cm/sec vibration with 50dB noise and 0.9cm/sec vibration with 60dB, the previous one show a faster reaction speed than the later one. Futhermore the later one showed that pulling up on their shell, in order to avoid the epidemic, moving around, small organisms are included to hide under big organisms, alerting posture. However we couldn't find a consistent standard in our research.
