국내 유통 중인 우육 및 돈육을 대상으로 S. aureus의 오염실태와 검출된 S. aureus 대한 항생제 감수성조사 및 내성 plasmid 전달빈도를 조사하였다. 총 421개 축산물 시료의 20.2%에서 S. aureus가 검출되었으며, 품목별로는 돈육 13.9%, 우육 33.8%의 검출률을 보였다. 가공 전 원료육이 포장육에 비해 S. aureus의 검출률이 높았는데, 돈육에서는 원료육 23.3%, 포장육 7.1%였고, 우육에서는 각각 48.6% 및 28.1%였다. 항생제 감수성 시험결과 ampicillin(76.5%), penicllin(75.3%), tertracycline(27.1%) 및 erythromycin(21.1%) 순으로 높은 내성률을 보였다. 특히 우육에서는 penicillin의 내성이 55.6%인 반면 돈육에서는 97.5%로 돈육에서 1.6배 이상의 높은 내성률을 보였고, tetracycline의 경우 우육에서 13.3%의 내성을 보인 반면, 돈육에서는 42.5%로 3배 이상의 내성률을 보였다. 8가지 항생제에 내성을 보이는 다제내성균도 검출되었으며, 약제내성과 관련된 Rplasmid의 특성시험에서 혼합배양에서는 내성이 전달되지 않았고, filter mating법에서 tetracycline내성 plasmid가 1.1×10<SUP>-5</SUP>~1.9×10<SUP>-9</SUP>의 빈도로, erythromycin 내성 plasmid가 1.2×10<SUP>-5</SUP>~4.0×10<SUP>-8</SUP> 빈도로 내성이 전달되었다. 따라서 국내에서는 항생제투입의 정량적인 규제나 법적인 제도장치의 마련이 시급하다고 생각되며 앞으로 항생제 사용규제 및 대책마련에 대한 추가적인 연구가 절실하다고 생각되었다. Staphylococcus aureus is a pathogene of major concern in livestock products. This study was conducted to test imported and domestic meat sold by retail stores for the presence S. aureus. In addition, the antibiotic susceptibility of any S. aureus found was also evaluated. The overall isolation rate of S. aureus was 20.2% (13.9% in pork and 33.8% in beef) in retail meats. The percentage of imported meats found to contain S. aureus (33.3% in pork and 40.4% in beef) was higher than that of domestic meat (13.0% in pork and 14.7% in beef). In addition, the detection rate of S. aureus was higher in raw material meat than in ready to cook packaged meat. When the antibiotic susceptibility of S. aureus isolated from the meat products was evaluated, ampicillin was found to be the highest (76.5%), followed by penicillin (75.3%), tetracycline (27.1%) and erythromycin (21.2%). Penicillin and tetracycline resistant were detected in 55.6% and 13.3% of the beef isolates, respectively, and 97.5% and 42.5% of the pork isolates, respectively. The tetracycline and erythromycin resistant plasmids of the isolated strain were transferred into S. aureus DPRMM2429 by the filter mating method and the frequencies of transfer was found to be 1.1×10<SUP>-5</SUP>~1.9×10<SUP>-9</SUP> and 1.2×10<SUP>-5</SUP>~4.0×10<SUP>-8</SUP> respectively.

목적 본 연구는 한국의 국가수준 유치원 평가에 대한 깊이 있는 이해를 위함이다. 방법 G시의 사립유치원에 근무하고 있는 유치원 원감 4명을 중심으로 심층면담을 실시하였다. 이들은 유아교육기관의 중간관리자로서 평소 유치원평가에 대해 많은 관심을 가지고 있었고, 실제 운영하고 있는 유치원 프로그램과 국가수준 교육과정 운영이라는 국가적 책무성 사이에서 많은 고민과 갈등을 겪고 있었다. 결과 유치원 중간관리자(원감)가 경험한 국가수준의 유치원평가는 크게 시간으로부터 오는 어려움과 현재 소속된 유치원에서 운영하고 있는 교육프로그램과는 다른 누리과정을 바탕으로 이루어지는 평가지표로 인한 어려움, 그리고 유아, 교사, 원장 등 사람과의 관계로부터 오는 어려움으로 나뉘어졌다. 또한 한국의 향후 더 나은 국가수준 유치원평가로 나아가기 위한 방향성을 제시하기도 하였는데, 컨설팅이나 멘토링제도 도입 필요, 평가위원의 전문성 요구, 다양한 프로그램 평가지표 도입이 하루 속히 이루어져야 한다고 주장하였다. 결론 이러한 연구결과는 국가수준 유치원 평가에서 각 기관의 실정에 적합한 평가체제 마련과 관계자의 충분한 연수, 전문성이 높은 평가위원의 선정 등과 같은 유치원 평가의 질적 향상을 위한 개선, 보완이 필요함을 시사하고 있다. Objectives The purposes of this study explored lived experiences of four kindergarten vice-principals in G city with the national kindergarten evaluation in South Korea. Methods A total of 12 in-depth semi-structured interviews were conducted for data collection. The participants, as mid-level administrators, had high interests and stakes in kindergarten assessment, as well as practical difficulties and emotional conflicts between complying with national curriculum including evaluation criteria and running programs based on their own pedagogical beliefs and valued practices. Results Their experienced difficulties were categorized into a) time and labor constraints, b) discrepancies between evaluation criteria/indicators and their program characteristics, and c) relational difficulties among children, teachers, and administrators along the evaluation procedure. Conclusions The findings suggest the need for reflecting institutional contexts in evaluation criteria and process, communicating with and training for stakeholders, and selecting qualified validators.

배경: 삼출성 흉수 환자의 적지 않은 빈도에서 원인이 불명확하다. 삼출성 흉수를 진단하기 위한 다양한 방법 중에서 내과적 흉강경은 국소마취 하에서 시행할 수 있으며 악성 종양이나 결핵에서 진단율이 높으며, 진정제와 국소마취상태에서 시행할 수 있다. 본 연구의 목적은 내과적 흉강경의 진단적 정확성과 안전성에 대해 알아보고자 하였다. 대상 및 방법: 2005년 10월부터 2006년 9월까지 25명의 원인을 알 수 없는 삼출성 흉수 환자를 대상으로 내과적 흉강경을 시행하였다. 성별, 연령 시술 전 폐기능, 흉부 측와위 사진에서 흉수의 두께(LDR) 등의 정보를 얻었다. 내과적 흉강경 시행도중 활력징후를 기록하였고 동맥혈 가스 분석을 5차례 시행하여 혈역학적 상태와 산-염기 균형 상태를 파악할 수 있도록 하였다. 결과: 환자의 평균 연령은 56.8(22-79)세였고, 흉부 측와위 사진에서 흉수의 두께는 27.49 mm이었다. 내과적 흉강경을 이용한 흉막 조직 생검으로 24명(96%)이 진단되었으며, 결핵성 흉막염이 9명(36%), 악성 흉수가 8명(32%), 부폐렴성 흉수가 7명(28%)이었다. 내과적 흉강경으로 흉수의 원인을 알아낼 수 없었던 1명(4%)은 추후에 심장막 조직 생검으로 결핵으로 진단되었다. 내과적 흉강경 중 혈압, 심박동수, 산-염기 상태의 변화는 보이지 않았다(p>0.05). 결론: 내과적 흉강경은 진단율이 높으면서도 안전한 시술이다. Background: The causes of the pleural effusion are remained unclear in a the substantial number of patients with exudative effusions determined by an examination of the fluid obtained via thoracentesis. Among the various tools for diagnosing exudative pleural effusions, thoracoscopy has a high diagnostic yield for cancer and tuberculosis. Medical thoracoscopy can also be carried out under local anesthesia with mild sedation. The aim of this study was to determine diagnostic accuracy and safety of medical thoracoscopy. Methods: Twenty-five patients with exudative pleural effusions of an unknown cause underwent medical thoracoscopy between October 2005 and September 2006 in Konyang University Hospital. The clinical data such as age, gender, preoperative pulmonary function, amounts of pleural effusion on lateral decubitus radiography were collected. The vital signs were recorded, and arterial blood gas analyses were performed five times during medical thoracoscopy in order to evaluate the cardiopulmonary status and acid-base changes. Results: The mean age of the patients was 56.8 years (range 22-79). The mean depth of the effusion on lateral decubitus radiography (LDR) was 27.49 mm. The medical thoracoscopic pleural biopsy was diagnostic in 24 patients (96.0%), with a diagnosis of tuberculosis pleurisy in 9 patients (36%), malignant effusions in 8 patients (32%), and parapneumonic effusions in 7 patients (28%). Medical thoracoscopy failed to confirm the cause of the pleural effusion in one patient, who was diagnosed with tuberculosis by a pericardial biopsy. There were no significant changes in blood pressure, heart rate, acid-base and no major complications in all cases during medical thoracoscopy (p>0.05). Conclusions: Medical thoracoscopy is a safe method for patients with unknown pleural effusions with a relatively high diagnostic accuracy. (Tuberc Respir Dis 2007; 63: 261-267)

Objective: This study aimed to apply Bridging Assessment, an activity-based assessment, in early childhood classrooms in South Korea to examine its possibility as an alternative tool to assess young children’s developing language and early literacy language skills. Methods: The participants included one daycare center teacher, two public kindergarten teachers, and 18 children (4–5 years old). Data from participatory observations; consultations after each evaluation activity; in-depth interviews, phone conversations, and e-mail correspondences with teachers; child assessment record sheets; teacher journals; and daily research logs were collected, transcribed, and analyzed using QSR NVivo 10.0. Results: Bridging Assessment activities in language arts and literacy consisted of the following: (a) reading a child’s favorite book and one book of the teacher’s choice to evaluate the children’s abilities as early readers, (b) dictating a story to examine the children’s storytelling abilities, and (c) acting out a story composed by the children through the story dictation activity to assess their comprehension and expressions. Responses from the participating children and teachers indicate that these assessment activities could take place within the Nuri curriculum. The fact that the children showed improved dramatization skills in the dramatic plays implies a need to make more active use of story dramatization in early childhood classrooms. Conclusion: Overall, the findings indicate the potential for activity-based assessments to evaluate and facilitate young children’s language and literacy skills via activity-based processes and indicative rubrics and call for more diverse and active development and utilization of such alternative assessments.

협력적 실행연구를 통한 초임 유아교사의 유아관찰 평가의 실천과 반성
양정은(Jung-Eun Yang) 한국엔터테인먼트산업학회 2020 한국엔터테인먼트산업학회논문지 Vol.14 No.5
유아를 평가하는 과정에서 교사의 역할이 매우 중요함에도 불구하고, 교직 입문 과정에서 초임 유아교사들은 충분한 배경지식이나 실제적 지도능력을 갖추지 못하고 있어 상당한 어려움을 겪고 있다. 본 연구에서는 협력적 실행연구를 통하여 한 초임 유아교사가 ‘유아관찰평가’에 대한 신념과 실제를 반성적으로 바라보고 실천적으로 개선해나갈 수 있도록 지원하고자 한다. 실행연구의 순환과정을 통해 참여교사는 유아관찰평가에 대한 자신의 신념과 접근방식을 반성적으로 들여다봄으로 스스로를 성장시키는 계기가 될 것이다. 본 연구결과를 바탕으로 초임 유아교사의 교직입문을 지원할 수 있는 하나의 방안으로 협력적 실행연구의 적용을 제안하고자 한다. Despite evidence that early childhood teachers play a critical role in guiding children through their child assessment, most beginning teachers in the survival stage face the greatest difficulties in this area. Using the intentional and purposeful tools of action research, this collaborative action study supports a beginning teacher in reflecting upon her perceptions of the "child assessment" of young children and devising and evaluating good guidance practices. During the course of the study, the participating teacher became engaged in more reflective teaching which prompted her to perceive the “child assessment” of the children from different perspectives. As her understanding of the importance of making her curriculum and classroom climate more engaging and meaningful deepened and she reconceptualized her notion of child assessment, the teacher witnessed positive changes in her students" behaviors which, in turn, increased her sense of efficacy. These very positive, empowering results are strong recommendation for using collaborative action research especially in the novice years of teaching for it provides the teacher with a life-long transformative tool for professional development.

This study was conducted to investigate the prevalence of elementary student with ADHD (Attention Deficit - Hyperactivity Disorder) in rural area of Korea and to analyze the relation to dietary habits and physical growth statues. The subjects were 109 students (boy 53. girl 56) from 13 elementary school located in H gun. Jeollanamdo. Body weight and height were measured. The growth statues of students were estimated by percentile of growth chart from Korean adolescents. The diagnosis of ADHD and dietary behavior were conducted using DSM-Ⅳ diagnostic questionnaire and self diagnostic dietary habit questionnaire, respectively. Data were analyzed by the SPSS program. Five students (4.6%) were defined as conclusive ADHD and forty students (36.7%) were detected having ADHD tendency. The students with normal growth statues were lower in students with conclusive/tendency ADHD compared to other students. However there was not statistical significance. Overall dietary behavior score was not significantly different between students with conclusive/tendency ADHD and normal students. However dietary habits score as follows, eating evenly with meal, eating fruits over one times a day and eating sea weed over one times a day were significantly lower in students with conclusive/tendency ADHD then normal students. These results suggested that the prevalence of ADHD in elementary students in rural area of Korea was similar to western country. The dietary habits were related to ADHD and it’s influenced to physical growth statues of the students.

유아기의 공격성은 개인의 건강한 발달에 부정적인 영향을 미치고 장시간에 걸쳐 지속적으로 유지되며, 사회적인 문제로 발전될 가능성이 높기 때문에 중요하게 다루어져야 한다. 이에 본 연구에서는 미술치료기법의 하나인 콜라쥬 기법을 이용한 프로그램을 공격성이 높은 유아에게 적용하여 유아의 공격적 행동에 미치는 효과를 살펴보았다. 연구결과 콜라쥬 기법을 경험한 유아들은 경험하지 않은 유아들에 비해 외현적 공격성과 내재적 공격성 감소에 있어서 유의미한 효과가 있는 것으로 나타났다. The purpose of this research was to understand the influence of Collage Program upon the decrease of aggression of young children. The objects of the research were taken from 60 young children under five of two classes of kindergarten in Chungnam checked up their aggression. Among them, 15 young children who showed a grade higher than 30 in external examination and a grade higher than 4 in internal examination were selected each class. Collage Programs were proceeded 14 times altogether(twice a week for 7 weeks, 50 minutes each) for the test group, with no program conducted for the control group. In order to discover the influence upon external aggression, teachers in charge of each class made prior examination and subsequent assessment(after all of the 14 times) to estimate external aggression of the young children. In the examination of internal aggression, researcher and teachers in charge of each class estimated prior and subsequent assessment before and after the introduction of Collage Program. Standard deviation was in terms of statistical method on average. And variation of internal and external aggression were examined through the T-test of the difference between the prior grade and the subsequent grade. The result of the research showed that the external aggression of the test group after the Collage Program decreased significantly, compared with the control group for which Collage Program had not been proceeded. Moreover, a significant difference of the grade of internal aggression between the two groups was observed. Therefore the positive influence of Collage Program upon the aggression of young children can be concluded.
