김은선 한국초등국어교육학회 2025 한국초등국어교육 Vol.80 No.-

이 연구는 초등학교 학생들이 교사와 인공지능이 제공한 글쓰기 피드백에 대해 어떤 반응을 보이는지 살펴보는 것을 목적으로 한다. 최근 교육 현장에서 인공지능 기반 피드백 시스템의 활용이 확대되고 있으나, 이에 대한 학습자들의 실제 반응을 살핀 연구는 부족하다. 이에 본 연구는 초등학교 5학년 학생들이 교사와 인공지능이 작성한 피드백을 읽고 보이는 반응을 탐색하였다. 먼저, 학생들에게 쓰기 과제를 제시하고, 교사와 인공지능이 이에 대한 피드백을 작성하였다. 다음으로, 학생들에게 피드백의 작성 주체를 밝히지 않은 상태에서 피드백에 대한 인상을 조사하였으며, 작성 주체를 밝힌 후 학생들의 반응도 수집하였다. 면담과 설문을 통해 수집한 학생들의 반응은 질적으로 분석하였다. 이 연구는 피드백에 대한 학생들의 반응을 분석함으로써, 향후 교사 피드백 전략 수립과 인공지능 기반 글쓰기 피드백 시스템 설계에 유용한 시사점을 제공할 수 있을 것으로 기대된다. The purpose of this study is to examine how elementary school students react to writing feedback provided by teachers and AI. Therefore, this study explored the reactions of fifth grade elementary school students when they read writing feedback provided by teachers and AI on their own writings. Initially, students completed a writing assignment, after which feedback was generated by a teacher and an AI system. Students were first asked to reflect on the feedback without being informed of its source. Subsequently, their reactions were collected again after disclosing the authorship of the feedback. The students’ responses were collected through interviews and questionnaires and analyzed qualitatively. By analyzing the students’ responses to feedback, this study is expected to provide implications for establishing teachers’ feedback strategies and designing AI writing feedback systems in the future.

Background/Aims: Early diagnosis and appropriate antimicrobial choice are crucial when managing pneumonia patients, and quantitative culture of bronchoalveolar lavage (BAL) fluid is considered a useful method for identifying pneumonia pathogens. We evaluated the quantitative yield of BAL fluid bacterial cultures in patients being treated with antimicrobials and attempted to identify factors predictive of positive BAL cultures. Methods: Patients over 18 years old and whose BAL fluid was subjected to quantitative culture to identify the organism causative of pneumonia between January 1, 2005, and December 31, 2009, were included. We reviewed the results of BAL fluid bacterial cultures and the clinical records, laboratory tests, and radiographic findings of the patients. Results: BAL was performed on 340 patients with pneumonia. A positive BAL culture, defined as isolation of more than 104 colony forming units/mL bacteria, was documented in 18 (5.29%) patients. Of these, 9 bacteria isolated from 10 patients were classified as probable pathogens. The most frequently isolated bacteria were methicillin-resistant Staphylococcus aureus, Acinetobacter baumannii, and Pseudomonas aeruginosa. No independent predictive factor for positive BAL cultures was identified. Conclusions: The yield of quantitative BAL fluid bacterial culture in patients already on antimicrobials was low. Clinicians should be cautious when performing a BAL culture in patients with pneumonia who are already on antimicrobials.

Purpose : The purpose of this study is to make a diagnostic classification and discuss a diagnostic strategy of floppy infants by investigating clinical, neurological, electrophysiological, and genetic analysis of infants admitted to intensive care units with the complaint of hypotonia. Methods : A retrospective study was performed from Jan. 1993 to Dec. 2005 in neonatal and pediatric intensive care units of Seoul National University Children's Hospital. Clinical features and all tests related to hypotonia were investigated. Results : There were 21 cases of floppy infants admitted to intensive care units. Final diagnosis was classified as centra (7 cases[33.3 percent]), peripheral (11 cases [52.4 percent]), and unspecified (3 cases [14.3 percent]). Among the central group, three patients were diagnosed as hypoxic ischemic encephalopathy, two patients as Prader-Willi syndrome, one patient as chromosomal disorder, and one patient as transient hypotonia. Among the peripheral group, four patients were diagnosed as myotubular myopathy, three patients as SMA type 1, two patients as congenital myotonic dystrophy, one patient as congenital muscular dystrophy, and one as unspecified motor-neuron disease. Motor power was above grade 3 on average, and deep tendon reflex was brisk in the central group. Among investigations, electromyography showed 66 percent sensitivity in the peripheral group, and muscle biopsy was all diagnostic in the peripheral group. Brain image was diagnostic in the central group, and Prader-Willi FISH or karyotyping was helpful in diagnosis in central group. Morbidity and mortality was more severe in the peripheral group Conclusion : Classification of diagnosis by clinical characteristics in this study, and application of investigations step by step, may provide an effective diagnostic strategy. 목 적 : 늘어지는 증상을 주소로 신생아 및 소아 중환자실에 입원한 영아들의 임상적, 신경학적, 전기생리학적 소견 및 유전적 진단 결과를 통한 분석을 통해 늘어지는 영아 증후군의 진단적 분류 및 진단 방법에 대한 고찰을 하고자 하였다. 방 법 : 1993년도부터 2005년까지 13년간 서울대학교 병원 어린이병원 신생아 중환자실 및 소아 중환자실에 늘어지는 증상을 주된 주소로 입원한 영아들을 대상으로 하였다. 후향적 의무기록 조사를 통해 임상 소견 및 검사 소견들을 조사하였고 최종 진단명을 분류하였다. 결 과 : 늘어지는 증상을 주소로 내원한 영아들은 21명이었다. 최종 진단명은 중추성 기원이 7명(33.3%), 말초성 기원이 11명(52.4%), 나머지 3명은(14.3%) 두 그룹 중 어느 그룹으로도 분류되지 못하였다. 중추성 기원은 저산소-허혈성 뇌증이 3명으로 가장 많았고, 그 외에 Prader-Willi 증후군 2명, 염색체 이상 1명, 일과성 저긴장증 1명이 있었다. 말초성 기원은 myotubular 근병증이 4명으로 가장 많았고, SMA 1형이 3명, 선천성 근긴장성 이영양증 2명, 선천성 근이영양증 1명, 그 외 분류되지 않은 운동신경질환 1명이 있었다. 가족력이 있었던 경우는 말초성 그룹에서만 3명이 있었고, 신경학적 검진 상 근력은 중추성 그룹에서 평균 Grade 3 이상이었고 건반사도 활발하게 나타난 경우가 많아 다른 그룹의 환자들과 차이를 보였다. 검사상의 소견은 근전도 검사에서 말초성 그룹이 66%의 민감도를 보였고 근생검은 말초성 그룹에서 진단적이었다. 중추성 그룹에서 뇌 영상 검사가 진단적이었고 진단율이 높지는 않았지만 Prader-Willi FISH 나 염색체 검사를 통해 진단이 되었던 경우가 있었다. 그 외의 분자 유전학적 검사로 확진 가능한 말초성 그룹의 환자들이 있었다. 입원 기간 및 기관 삽관 기간은 말초성 그룹에서 현저하게 길었고, 추적 관찰 시 사망 및 심한 발달 지체의 비율도 말초성 그룹에서 높게 나타났다. 결 론 : 본 연구의 늘어지는 영아들의 임상상을 바탕으로 진단적 분류를 시행하고 각 진단 분류에 유용한 검사를 순서대로 진행시킨다면 효과적인 진단이 이루어질 수 있을 것이다

Pseudomonas carboxydovorans 에서 분리한 일산화탄소 산화효소의 Subunit 구조

김은선,김영민 ( Eun S . Kim,Young M . Kim ) 생화학분자생물학회 1984 BMB Reports Vol.17 No.2

A carbon monoxide oxidase (CO oxidase) from CO-autotrophically grown cells of Pseudomonas carboxydovorans was purified through conventional purification methods to study the subunit structure of that enzyme. Activity staining after non-denaturing PAGE (polyacrylamide gel electrophoresis) showed that the purified enzyme is an active CO oxidase. PAGE in the presence of sodium dodecyl sulfate revealed at least three kinds of non-identical subunits of molecular weights 14,000, 25,000, and 85,000, respectively, are present in the enzyme. This result is in accord with the report of Kim et al. (FEMS Microbiol. Lett. 13 : 219-223, 1982) but not with that of Meyer and Schlegel (J. Bacteriol. 141:74-80, 1980). Two possible reasons for the different reports on the subunit structure of the CO oxidase are briefly discussed.
