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.

Choi,Seong-Kyu,Yun,Kyeong-won,Chon,Sang-Uk,Lee,Jong-Ill,Seo,Young-Nam,Seo,Kyoung-Sun,Choi,Kyeong-Ju 한국자원식물학회 2004 Plant Resources Vol.7 No.3

This study was conducted to develop effective production system in greenhouse for leaves and stems of Angelica acutiloba by using connect pots in 2003 and 2004. Seed germination rate and plant biomass of Angelica acutiloba collected in 2004 were higher than those harvested in 2003. Germination rate of Angelica acutiloba seeds collected in 2003 was 10%, while germination rate of seeds collected in 2004 was above 90%. Especially, plant growth and yield of Angelica acutiloba grown in connect pots sized with 4×4×5cm(length×width×height) were the highest. These results indicate that leaf and stem production of Angelica acutiloba can be improved by using connect pots and optimizing seed collecting time in greenhouse.

Heat stroke is a life-threatening illness characterized by an elevated core body temperature that rises above 40% and central nervous system dysfunctions that results in delirium, convulsions, or coma. Heat stroke is subdivided into two forms, classic and exertional. Since strenuous exercise is one of the major exacerbating and precipitating factors, the incidence of exertional heat stroke is high among young adult, especially military personnel undergoing military training. Exertional heat stroke commonly causes rhabdomyolysis, lactic acidosis, acute renal failure, shock and pulmonary edema. We report a case of heat stroke with rhabdomyolysis, acute renal failure, disseminated intravascular coagulopathy(DIC) after strenuous exercise. A 18 year old man was admitted to the hospital because of loss of consciousness. He was a wrestler and he had tried to lose 6kg in weight by jogging and strenuous exercise on that summer day with hot temperature. The development of this illness was favoured by much clothes inappropriate for that environmental condition with a purpose to enhance sweating, and by restricted intake of water and food. On admission, the blood pressure was 80/50mmHg, and body temperature was 39.4℃ with stuporous mentality. Laboratory finding were as follows : in complete blood cell count, hemoglobin was 16.7g/dL and platelet count was 158,000/ mm³. In blood chemistry, AST 1061U/L, ALT 201U/L, BUN 30mg/dL, Cr 2.2mg/dL, LDH 941IU/L, CK 696IU/L were resulted. In arterial blood gas analysis, pH 7.39, pCO₂ 30mmHg pO₂ 86mmHg, HCO₃ 18.4mEq/L, O₂ saturation 96.7% were resulted. In urinalysis, specific gravity 1.025, protein 3+, erythrocyte 2+ were resulted. In brain imaging study, brain CT finding was normal. After appropriate treatments with rapid cooling, hydration and supportive care, he improved with alert mental status. On 2nd hospital day, in laboratory result, thrombocytopenia and coagulopathy were appeared and renal insufficiency was aggravated. So he was treated with platelet concentrate and fresh frosen plasma for DIC, and enough hydration for appropriate urine volume preservation. After all, On 22nd hospital day, he fully recovered and discharged. Nowadays, with followed for some duration, he is wellbeing with no complications.

신비체험과 해리성향과의 관계

최낙경,이상혁,우용일,이만홍,현용호 대한신경정신의학회 2000 신경정신의학 Vol.39 No.4

신비체험은 종교의 핵심경험이라고 일컬어질 만큼 종교계에서 가치 있게 평가되고 있으며 여러 사회집단에서도 관심의 대상이 되어왔다. 오래 전부터 심리학자들과 정신의학자들이 신비체험에 대해 관심을 가져 왔지만 그것의 개인적이고 주관적인 특성 때문에 과학적인 접근이 어려웠으며 단지 신비체험의 특성을 나열하고 묘사하는데 그쳤다. 최근 일부 정신병리학자들은 신비체험을 해리현상의 하나로 보는 주장도 있다. 한편 해리는 어린 시절의 외상경험과 연관이 있고 정신병리가 많을수록 해리경향성이 높아진다는 보고가 있어 왔다. 본 연구는 종교인중 신비체험을 경험하지 않은 사람(비신비체험군) 35명을 대조군으로 하여 종교인중에서 신비체험을 경험한 사람(신비체험군) 42명과 해리경향성, 정신병리, 외상경험을 비교하였다. 연구도구로는 한국어판 해리경험 척도, 간이정신진단검사, 외상유무를 묻는 질문지를 이용하였다. 그 결과, 해리경향성은 신비체험군이 비시비체험군보다 유의미하게 높았으며 외상경험도 유의미하게 높게 보고하였다. 그러나 정신병리상의 두드러진 차이는 발견되지 않았다. Mystic experience is highly evaluated so as to be called as core of experience in the religious world and also becomes the subject of concern among various social groups. Psychologists and psychiatrists are concerned about it, but because of its individuality and subjectivity, the scien-tific approach was difficult so that only the description of mystic experience has been researched fo far. There is a current report saying that mystic experience is the one of the dissociative pheno-menon. And there are a lot of reports saying that dissociation is related to childhood trauma experience and rises as much as psychopathological tendencies exist. Consequently, based on the reference that mystic experience is connected with dissociation, the study has been progressed to find out the level of dissociation, psychopathology and trau-ma experience for religious people who experienced mystic experience but excluding patients. Among them, it has been compared between group of non-mystic experience(n=35) and group of mystic experience(n=42). We used Dissociative Experience scale-Korean version(DES-K), Symptom Checklist-90-Revised(SCL-90-R), questionnaire about trauma. The result is that the group of mystic experience had a significantly higher tendency to have dissociation and trauma experience than group of non-mystic experience. However, the differ-ence of psychopathology has not been found.

This study was made to find out the effective and convenient preserving methods of surplus colostrum for dairy farms. Colostrum from 5 cows, was divided into the following treatments:naturally fdrmented, acetic acid treated, antibiotics treated, starter treated and frozen. The results on the microbiological and nutritional change of treated colostrum strore during warm ambient temperature from 22' to 33'C are summarized as follwoings : 1. pH of fresh colostrum was decreased to 4.1 to 4.3 within 10 days of storage, and no more decline was observed in preserved colostrum after 10 days. 2. Number of total bacteria, coliform bacteria and lactic acid producing bacteria increased rapidly during the first 3 days of fermentation. After 3 days of storage nember of coliform bacteria declined whereas number of total bacteria and lactic acid producing bacteria were not changed greatly. 3. Number of coliform bacteria was lowest in acid treated colostrum and early increased lactic acid producing bacteria was observed in starter treated group. Antibiotics treatment failed to decrease number of coliform bacteria, on the other hand lactic acid producing bacteria was inhibited by antibiotics added. 4. Total solids, fat and lactose in colostrum decreased with storage time in all treatments. However, the losses were highest in naturally fermented colostrum of all treatments. with nearly no loss in frozen colostrum. 5. No significant loss of total N was observed, however and colostral NPN increased rapidly with storage time in all treatments, with highest increase in naturally fermented colostrum. Immunoglobulins were not decreased during storage time. 6. Rapidly decreasing titratable acidily was observed in 10 days of storage especially in naturally fermented, acid treated and starter treated colostrum. 7. In conclusion, frozen colostrum was identified perfect method of preservation and acid treatment was also effective and economical on microbiological and nutritional viewpoint.

The purpose of this study was to identify obstacles by surveying dieticians' perception in implementing Generic HACCP Plan for school foodservice operations from 2001. The survey was conducted in five areas; Seoul, Kyoung-gi Province, In-cheon, Kwang-ju and Dae-jean. Five hundred and sixty questionnaire were sent by the e-mail address and the local school dietician's Community Board on the internet, 263 were returned. Two hundred and forty were returned by E-mail, return rate was 42.86%. Twenty three were received by the local school dietician's Community Board on the internet. The obstacles were grouped of six fields and indicated thirteen factors in implementation of the Generic HACCP Plan for school foodservice. The six fields were 'status of cooperation within HACCP team', 'cooperation with the external people' such as teachers, food suppliers, student's parents, 'understanding HACCP system of the dieticians', 'hygiene facilities', 'training & educating employees', and 'monitoring'. We used Likert's scale to assess the factor as a obstacle : 5-agree strongly, 4-agree, 3-medial, 2-don't agree, 1-dont't agree strongly. Results of this study are as follows; 1) The scores of thirteen factors indicated as obstacles were over 3(medial) except 'lack of dietician's understanding about HACCP System(2.86±0.97)'. Also only about 63% dieticians recognized that as an obstacle factor. 2) 'Deficiency of hygiene facilities(4.41±0.76)', 'lack of teachers' cooperation(4.23±0.77)', 'inadequacy of the kitchen lay-out(4.19±0.95)' and 'lack of training and educating program for employees(3.97±0.85)' scored most highly. Results from this study show that financial resources and educating system are very important to settle down HACCP system for School Foodservices successfully.
