심예지 한국중앙영어영문학회 2012 영어영문학연구 Vol.54 No.3

The objective of this thesis is to determine the extent to which second language learners can improve their language capacities using a specific set of online instruction materials, an Online Studyboard Community (OSC). Several years ago, the online tool was adopted by a number of universities in Korea. Since then, many instructors have started using online teaching materials to teach English. The thesis examines the role played by the Online Studyboard Community (OSC) in supporting the self-study activities of the second language learner. The thesis makes suggestions concerning the best methods of constructing an effective OCS for a second language teaching program. The study examined how Internet-based instruction influenced the English language learning experience of a select group of university students and also analyzed the instructor-student classroom interaction within the language community on the Web and its effect on the overall learning experience.

심예지,이건수,김욱현,서진경,백새윤,현신영 대한혈액학회 2014 Blood Research Vol.49 No.4

Background Continuous infusion of factor VIII (FVIII) is a more cost-effective method for treating hemophilia A than intermittent bolus injection. However, there is currently no specific data in Korea about the progress of in vitro FVIII coagulant activity (FVIII:C) after reconstitution from its lyophilized form. Methods Three commercial FVIII concentrate products (two recombinant FVIII and one plasma-derived) were used. In vitro FVIII:C was measured at 0, 2, 4, 6, and 8 hours following reconstitution in both the indoor light-exposed and light-shielded groups. Results For the three drugs, in vitro FVIII:C decreased over the 8 hours following reconstitution (P<0.001). The decline of FVIII:C was linear (P<0.001). In vitro FVIII:C for the indoor light-exposed groups was 95.3±1.9% and 90.6±2.5% after 4 and 8 hours following reconstitution, respectively, compared to baseline activity. In the light-shielded group, FVIII:C was 95.4±1.1% and 90.9±1.7% of the baseline activity after 4 and 8 hours, respectively. There was no statistical difference between FVIII:C in the indoor light-exposed and light-shielded groups (P=0.849). Conclusion In vitro FVIII:C decreased after reconstitution, but activity was maintained at over 90% of the baseline value during 8 hours. Exposure to indoor light did not accelerate the loss of FVIII:C over the experimental time. This result indicates that CI with FVIII is available in 8-hour intervals, with no indoor light-exposure precautions needed.

심예지,김희진,서장수,이건수 대한의학회 2011 Journal of Korean medical science Vol.26 No.12

Severe congenital neutropenia is a heterozygous group of bone marrow failure syndromes that cause lifelong infections. Mutation of the ELANE gene encoding human neutrophil elastase is the most common genetic alteration. A Korean female pediatric patient was admitted because of recurrent cervical lymphadenitis without abscess formation. She had a past history of omphalitis and isolated neutropenia at birth. The peripheral blood showed a markedly decreased absolute neutrophil count, and the bone marrow findings revealed maturation arrest of myeloid precursors at the promyelocyte to myelocyte stage. Her direct DNA sequencing analysis demonstrated an ELANE gene mutation (c.607G > C; p.Gly203Arg),but her parents were negative for it. She showed only transient response after subcutaneous 15 μg/kg/day of granulocyte colony stimulating factor administration for six consecutive days. During the follow-up observation period, she suffered from subsequent seven febrile illnesses including urinary tract infection, septicemia, and cellulitis.

심예지,김정미,권순학,최병호 대한소아청소년과학회 2009 Clinical and Experimental Pediatrics (CEP) Vol.52 No.5

Purpose : To report the clinical experience with amitriptyline for managing children with cyclic vomiting syndrome (CVS). Methods : Totally, eleven children (eight males) were diagnosed with CVS. Of these, medical records were reviewed for eight children treated with amitriptyline; three children were not treated because one was not followed up and two were kept under observation to study the natural course without medication, because the frequency of vomiting had recently decreased to less than one episode per year. The eight amitriptyline-treated children were divided into three groups by the therapeutic response: (1) complete remission (CR), with no recurrence of symptoms after treatment; 2) partial remission (PR), in which the frequency of symptoms decreased by almost 50% after treatment; and (3) no response. Results : For the eight amitriptyline-treated children, the mean age of symptom onset was 4.7 (0.3-7) yr and mean age at diagnosis was 8.9 (6.0-11.3) yr. The mean number of vomiting episodes was 8.8 (2-25) per year, and the duration of vomiting in each episode ranged from 3 hours to 5 days. CR was achieved in five (62.5%) of the eight amitriptyline-treated children (0.2-0.8 mg/kg/day orally, at night) and PR was achieved in three children (37.5%). Two children relapsed on discontinuation of amitriptyline by their parents decision but showed improvement on remedication. No adverse effects were noted throughout the study period. Conclusion : Amitriptyline can be used in long-term prophylaxis for the management of children with CVS aged over 6 yr. However, a large-scale study is needed to ascertain its effects. 목 적 : 뇌신경계 질환이나 소화기계 질환을 포함한 기질적 질환 없이 주기적으로 발작적 구토를 보이는 주기성 구토 증후군(CVS, cyclic vomiting syndrome)의 증상 예방 요법에 관한 국내 연구가 거의 없는 실정이다. 본 연구는 저용량의 삼환계 항우울제인 amitriptyline을 투여하여 CVS 환자에서 구토 발생의 장기적인 예방 효과가 있는지 알아보고자 하였다. 방 법 : 총 11명(남아 8명)의 CVS 환자 중 8명(남아 6명)의 환자들에게 amitriptyline을 투약했고 이들의 의무기록을 후향적으로 분석하였다. 11명 중 구토의 빈도가 연 1회로 감소 중인 2명은 투약 없이 경과 관찰 중에 있고 한 명은 CVS 진단 후 외래 추적이 중단되어 분석에서 제외하였다. Amitriptyline 투여 군을 반응도에 따라 세 군으로 분류하고 특성을 분석하였다. 1) 완전 관해-치료 후 증상의 재발이 2주기 이상 없음. 2) 부분 관해-1주기 간 증상 재발이 없거나 증상의 빈도, 정도가 50% 이상 감소한 군. 3)무반응-호전 정도가 50% 미만이거나 호전 없음. 결 과 : 총 8명의 환자들의 증상이 발현된 시작 연령은 평균 4.7세(0.3-7), 진단 당시 평균 나이는 8.9세(6-11.3), 증상 발현 후 진단될 때까지 걸린 기간은 평균 4.3년(2-10.5), 증상 발현 후 amitriptyline 투여를 시작할 때까지 걸린 기간은 평균 4.9년(2- 10.5)이었다. 연간 발작적 구토의 에피소드는 평균 8.8회(2-25)이었으며 구토 발생시 구토 지속 시간은 3시간에서 5일이었다. 발작적 구토가 있을 때 동반되는 증상으로는 편두통이 2명(25%), 복통이 6명(75%), 어지러움이 2명(25%)에서 있었고 편두통 가족력이 있는 환자가 2명 있었는데 이들은 환자 본인도 구토 에피소드 동안 두통과 복통이 동반되었다. 검사상 위배출 지연이 있는 환자는 3명이었고 이들은 저용량 erythromycin을 함께 단기간 투약하였으며, 요소 호기 검사에서 양성을 보인 환자 1명과 부비동염이 있던 환자 1명은 항생제 치료를 단기간 병행하였다. 총 8명의 환자들 중 amitriptyline 예방 요법 후 증상의 완전 관해를 보인 환자는 5명(62.5%)이었고 부분 관해를 보인 환자는 3명(37.5%)이었으며 무반응자는 없었다. 8명 중 2명은 보호자가 임의로 약물을 중단하였다가 증상 재발을 경험하였으며 재투약 후 각각 완전 관해 및 부분 관해를 보였다. 8명 중 부분 관해군 환자 1명과 완전 관해군 환자 1명은 외래 추적이 중단되었고 1명은 17개월 투약 후 증상이 없어 투약을 중단하였으며 현재까지 경과가 양호하다. 나머지 5명은 현재까지 평균 23.6개월(12-31) 동안 예방 요법 지속 중에 있다. 특별한 부작용이 나타난 환자는 없었다. 결 론 : 본 연구의 대상이었던 CVS 환자 모두에서 amitriptyline은 구토 증상의 장기적인 예방 효과를 보여 amitriptyline을 6세 이상 CVS 환자에서 예방 요법으로 시도해 볼 수 있을 것으로 생각되나 대상 환자군이 적고 대조군이 없는 관계로 향후 더 큰 규모의 무작위 연구가 필요할 것으로 생각한다.

2009 개정 교육과정 초등 과학 지도서에 제시된 학습 목표 및 평가 문항 목표 분석과 과학 관련 태도 영역 문항 개발

심예지,정지호,박일우 한국현장과학교육학회 2017 현장과학교육 Vol.11 No.1

This study analyzed the learning and evaluation objectives presented in the guidebooks for elementary teachers and developed evaluation items that teacher can utilize in their lessons. For graders 3 and 4, 112 learning objectives of unit, 274 learning objectives of lessons, and 609 evaluation objectives in teachers guidebooks were analyzed. For graders 5 and 6, 175 learning objectives of unit, 274 learning objectives of lessons, and 609 evaluation objectives in teachers guidebooks were analyzed as well. The result showed that ‘knowledge’ category has the largest percentage of both learning objectives and evaluation objectives; ‘attitude’ category has the smallest percentage of both learning objectives and evaluation objectives. Especially the percentage of attitude in evaluation objectives was extremely small. In case of attitude, all of science-related attitude (attitude toward science, scientific attitude, attitude toward learning science) were presented in learning objectives. However, only scientific attitude was presented in evaluation objectives in guidebooks for teachers. The examples of evaluation items were developed and its implication was discussed. 본 연구는 2009개정 교육과정 초등 과학과 교사용 지도서에 제시된 단원별, 차시별 학습 목표와 평가문항 목표를 비교 분석하였으며, 분석 결과를 바탕으로 단위 수업에서 활용할 수 있으며 지도서에서 제시 가능한 평가 문항을 개발하였다. 3~4학년 군 지도서에 제시된 단원목표 112개, 차시목표 274개, 평가 문항 목표 609개와 5~6학년 군 지도서에 제시된 단원목표 175개, 차시목표 257개 평가 문항 목표 486개를 분석하였다. 2009 개정 교육과정 교사용 지도서에 제시된 학습 목표와 평가 문항 목표를 분석한 결과, 지식, 탐구, 태도 영역 순으로 제시된 비율이 높았다. 특히 평가 문항 목표에서 태도 영역이 차지하는 비율이 매우 낮았다. 태도 영역의 경우, 단원 및 차시 학습 목표에서는 과학에 대한 태도, 과학적 태도, 과학 학습에 대한 태도가 모두 제시 되어 있었으나 평가 문항 목표에서는 과학적 태도 영역만 제시되어 있었다. 이러한 분석 결과를 바탕으로 과학 관련 태도 영역의 평가 문항 예시를 개발하여 현장 적용 가능성을 논의하였다.

COVID-19 전⋅후 초등과학 평가 실태 분석 및 블렌디드 러닝 상황에서 평가 방법 제안: 포트폴리오와 루브릭을 중심으로

심예지,박일우 학습자중심교과교육학회 2022 학습자중심교과교육연구 Vol.22 No.23

목적 본 연구의 목적은 COVID-19 전⋅후의 초등학교 과학 수업의 평가 실태를 분석하고, 분석한 결과와 선행 연구를 바탕으로블렌디드 러닝에 적합하면서 교육과정 성취 기준 도달 정도를 확인하기에 수월한 평가 방법을 제안하는 데 있다. 방법 연구 목적을 달성하기 위하여 2019년부터 2021년까지 3년 동안 서울특별시 소재 13개 초등학교의 평가 계획을 분석하였다. 그리고 더 자세한 사항을 파악하고자 해당 초등학교의 담당 교사를 대상으로 설문 조사하였다. 실태 분석 결과를 토대로 블렌디드러닝 상황에서 지필 평가와 실험 관찰 평가의 문제점을 보완할 수 있는 방법에 관한 선행 연구를 분석하였다. 분석 결과를 토대로교육과정 성취 기준 도달 정도를 파악할 수 있고 역량 중심 평가에 적합한 평가 방법을 도출하고자 하였다. 결과 조사 결과는 다음과 같다. 첫째, 과학과 평가 분야의 수는 2019년에는 4개 분야를 모두 평가하였으나, COVID-19 상황 이후인 2020년에는 평균 1.85개, 2021년에는 평균 3.15개로 축소되었다. 둘째, 평가 방법은 COVID-19 상황 전⋅후 모두 지필 평가방법을 가장 많이 사용하였고, 그 비중은 COVID-19 상황 이후에 더 높아졌으며, 두 상황 모두 지필 평가 방법 다음으로 실험 관찰평가 방법을 사용한 것으로 조사되었다. 이러한 설문 조사 결과와 선행 연구를 분석한 결과로부터 블렌디드 러닝 상황에 적합한 평가방법으로 포트폴리오와 루브릭을 교사와 학생에게 함께 제공하는 평가 방법을 제안한다. 결론 블렌디드 러닝 상황에서 포트폴리오와 루브릭을 함께 제공하면 교사는 채점과 피드백의 부담을 줄일 수 있고 평가의 공정성유지에 도움을 받을 수 있으며, 학생은 학습 목표를 명확히 인지할 수 있고 자기평가와 반성에도 도움을 받을 수 있다. 그리고 포트폴리오와 루브릭을 온라인 플랫폼에서 활용하면 예측하지 못한 상황에서 수업 형태가 갑자기 변경되어도 교사와 학생 간 의사소통을활발하게 이어갈 수 있고, 수업과 평가를 연속적으로 실시할 수 있는 장점이 있다.

체계적 문헌 고찰을 통한 국내 과학 학습 부진 연구 동향 분석

심예지,박일우,주은정 한국현장과학교육학회 2023 현장과학교육 Vol.17 No.3

This study aimed to provide insights for future research on underachievers in science learning by analyzing definitions and selection criteria found in existing research within South Korea. For our research, we systematically reviewed domestic academic papers, master's theses, and doctoral dissertations published from 1981 to October 2022, which contained the keyword 'underachievement in science learning.' The analysis showed that few studies on underachievement in science learning were published until 2000. In terms of study design and research methods, the predominant approaches were efficacy verification studies and quantitative research, and the majority of studies involved middle school students. In addition, the definition of underachievers in science learning can be classified mainly into two categories: cases in which academic achievement in science subjects is lower than potential abilities, and cases in which academic achievement in science subjects is low regardless of potential abilities. The selection criteria for identifying underachievers in science learning included students who scored below a certain threshold or students who performed poorly relative to their peers. It was found that the screening tools for underachiever in science learning varied across studies. Some researchers used self-developed tools, while others utilized officially recognized evaluation instruments. Through this study, it is intended to provide implications for future research on underachievement in science learning.

Natural course of childhood chronic immune thrombocytopenia using the revised terminology and definitions of the international working group: a single center experience

심예지,김욱현,Jin Kyung Suh,이건수 대한혈액학회 2014 Blood Research Vol.49 No.3

Background The immune thrombocytopenia (ITP) criteria were newly standardized by the International Working Group. Thus, we analyzed the natural course of childhood chronic ITP to predict the prognosis based on the revised criteria. Methods The medical records of children with chronic ITP from May 2000 to February 2013 in our institute were reviewed. Results Forty-seven children with chronic ITP who were not undergoing corticosteroid therapy were included. Their initial platelet count was 23±25×10⁹/L, and age at diagnosis was 6.3±4.1 years. The follow-up period was 5.4±3.7 years. Among them, 44.7% (21/47) showed spontaneous remission and maintained a platelet count ≥100×10⁹/L. And 66.0% (31/47) maintained a platelet count ≥50×10⁹/L until the last follow-up date. The time periods required for the platelet count to be maintained ≥50×10⁹/L and ≥100 ×10⁹/L were 3.1±2.7 and 3.6±2.7 years. Age at diagnosis in the ≥50×10⁹/L group (5.7±4.4 years) was significantly lower than the age at diagnosis in the <50×10⁹/L group (7.4±3.3 years) (P=0.040). And follow-up period was the factor influencing prognosis between the ≥100×109/L group and <50×10⁹/L group (P=0.022). Conclusion Approximately 45% of children with chronic ITP recovered spontaneously about 3–4 years after the diagnosis and 2/3 of patients maintained a platelet count ≥50×10⁹/L, relatively safe state. Age at diagnosis of ITP and follow-up period were the factors influencing prognosis in this study.
