학생 및 대학 특성이 교수-학생 상호작용에 미치는 영향 분석
김세희,고장완 한국교육학회 2016 敎育學硏究 Vol.54 No.4
The purpose of the study was to identify what individual and institutional characteristics affect the level of student-faculty interaction (SFI). To achieve this objective, two-level hierarchical linear model analysis was employed. The sample was 18,195 undergraduate students attending 32 four-year universities who responded to the 2012 National Assessment of Student Engagement in Learning conducted by Korean Educational Development Institute. The dependent variable was SFI, which was about the frequency of interaction between students and faculty members. Individual-level independent variables included gender, father’s education level, mother’s educational level, year in college, major fields, participation in classes, interaction with other members in college, and perception on college’s supportive environment, and institutional-level independent variables consisted of location, institutional type, and size. The results of analysis revealed that parts of the individual-level variables, namely gender, year in college, engineering major, participation in classes, interaction with other members in college, and perception on college’s supportive environment, had a significantly positive effect on SFI, and that location, among institution-level variables, significantly affected SFI. Related policy implications were discussed. 본 연구의 목적은 교수-학생 상호작용에 영향을 미치는 학생수준 및 대학수준의 영향요인을 탐색하는 것이다. 이를 위해 한국교육개발원에서 실시한 2012 한국 대학생 학습과정에 관한 설문조사에 응답한 32개 4년제 대학의 학생 18,195명의 자료를 다층모형을 통해 분석하였다. 종속변인은 학생이 인식하는 교수와의 교류 정도를 측정한 교수-학생 상호작용이었으며, 학생수준 독립변인에는 성별, 아버지 학력, 어머니 학력, 학년, 전공계열, 수업참여, 다른 구성원과의 교류, 대학 강조점 인식이, 대학수준 독립변인에는 대학의 소재지, 설립유형, 규모가 포함되었다. 연구 결과, 학생수준에서는 남학생, 학년, 공학계열, 수업참여, 다른 구성원과의 교류, 대학 강조점 인식이 교수-학생 상호작용에 긍정적인 영향을 주는 것으로 파악되었으며, 대학수준에서는 비수도권 소재 대학의 교수-학생 상호작용이 수도권 소재 대학에 비해 높은 것으로 나타났다. 본 연구는 이러한 결과를 바탕으로 여학생과 수도권 대학 학생의 교수-학생 상호작용에 더욱 관심을 가질 필요가 있으며, 대학은 일방적인 강의식 수업을 지양하고 지도교수제를 기반으로 운영되는 동아리 및 학습 커뮤니티 활동을 장려해야 함을 제언하였다.

Electroencephalography (EEG) is an effective test in predicting severe cortical dysfunction associated with poor outcomes in adult patients, but its value in pediatric patients remains incomplete. To assess the prognostic value of EEG regarding sedative history and various etiologies, we performed a retrospective study of pediatric patients who had undergone EEGs at the pediatric intensive care unit (PICU) of Severance Hospital for 5 years. In-hospital mortality was measured for the primary outcome. Of the 113 patients who met our criteria, in-hospital mortality was observed in 43 patients (38.1%) and sedatives were used in 37 patients (32.7%). Patients who showed in-hospital mortality were more like to have higher EEG background scores and absent EEG reactivity (P

본 연구에서는 수은에 관한 미나마타 협약에 대응하기 위해 국내 산업에서 배출되는 수은 함유 폐기물에 대한 현황 조사를 2년간 실시하였다. 국제협약에서 언급한 배출원들을 검토한 후 국내 산업공정 및 실정에 맞게 제품/에너지 제조시설과 폐수/폐기물 처리시설로 구분하여 조사시설을 선정하였다. 일반조사와 정밀조사로 구분하여 시설 수와 시료 채취 주기 및 횟수를 결정하였다. 1차년도에는 US EPA 7473과 US EPA 7471B 분석법을 통해 모든 시료를 교차분석하였다. 1차년도 연구 결과를 바탕으로 2차년도에는 US EPA 7473을 주 시험방법으로 사용하여 시료를 분석하였으며, 고농도 수은 (100 mg/kg)을 함유한 시료의 경우에는 US EPA 7471B를 사용하여 재측정하였다. 더불어 국내 수은 함유 폐기물 배출 실태와 국내·외 수은 함유 폐기물의 중간 및 최종 처리 기술에 대한 자료를 수집하여 국내 실정에 맞는 적절한 관리 시스템을 제시할 수 있었다.
Unknown voices: Undergraduates` perceptions about collaborative writing on wiki
김세희,조은원,조문흠 한국교육공학회 2015 한국교육공학회 학술대회발표자료집 Vol.2015 No.1
Purpose of the study: Although wikis have been widely adopted to support collaborative writing in undergraduate classrooms, educators remain concerned about the level of student participation. Often educators reported that undergraduates were reluctant to actively participate in collaborative writing on wikis. However, very little empirical research has been conducted to investigate why undergraduates are reluctant to collaborate with others in writing on wikis. In this exploratory study, we examined undergraduates’ perceptions about collaborative writing on wiki. The specific research questions we posed were as follows: Y What are undergraduates’ expectations about collaborative writing on wiki? Y What are undergraduates’ perceptions about giving and receiving feedback in collaborative writing on wiki? Y How do students evaluate their collaborative writing on wiki? Participants: A total of 27 undergraduates who were taking an educational psychology course participated in the study. Participation in the collaborative writing on wiki was a required class activity in the course and continued for five weeks. Students worked with group members and each group was composed of two to four students. Each group decided a research writing topic with the instructor and the topic should be relevant to issues in K-12. The data were collected from a university in the United States. Data collection and analysis: Open-ended questions were administered before and after the undergraduates participated in the collaborative writing on wiki. The specific questions will be presented at the KSET conference. For data analysis method, content analysis was conducted. Two researchers developed coding schemes and coded students’ written comments on each question. Initial consistency between two coders was 93% and discrepancy between two coders were solve through discussions. - Results: More specific research findings will be presented in KSET conference. Below is a list of findings through content analysis. Undergraduates had mixed expectations about collaborative writings on wiki. Some had high expectations including confidence about working with others, excitement about wikis, and positive expectation about group members. Some had concerns about collaboration on wiki. These concerns were over reliance to others and reluctance to collaborate with others. Undergraduates reported that they were comfortable to see other group members revise their writing on wikis. Many students appreciated constructive criticism from other members, correction of errors, and team collaboration. Few concerned that revision might change the intention of their contributions and felt uncomfortable about others’ revision on their writing if there was no discussions. In addition, undergraduates reported that they felt comfortable to edit other group members’ writing for successful completion of the group projects. They were also comfortable to edit minor errors such as grammar and spellings. However, some students mentioned that they didn’t want to upset or offend other group members and they believed each person had a different writing style and developed a different way to describe what they wanted to say. Discussions: We will discuss lessons we learned from the study. One of the lessons and suggestions we will make is that instructors provide an orientation about collaborative writing on wikis. The orientation focus on the nature of collaboration and research findings from the study that many students are comfortable to see others revise their writings. Revising and correcting errors are natural writing processes. In addition, we suggest that the instructors should provide opportunities for communication during class time. Students concerned that they may offend or upset others if they revise others’ writing on wiki. Lack of communication in face-to-face can cause misunderstanding about others’ intentions in collaborative writings. Regular face-to-face meetings can improve students’ understanding about each one’s writing styles and progress which will result in active collaboration among group members.

Genetic manipulation of pear (Pyrus pyrifolia Nakai) breeding is still difficult due to lack of reliable regeneration system. The aim of this research is to establish shoot regeneration system from leaf explants for pear (P. pyrifolia cv. Niitaka) using various concentrations of plant growth regulators and carbon source supplemented to medium. The highest regeneration rate of about 20% was found on a medium containing 4.4 g/L of Murashige and Skoog (MS) without vitamins, Linsmaier and Skoog (LS)vitamins were added separately. Leaf explants of pear were cultured on MS medium containing 7 g/L of Daishin agar supplemented with various concentrations of NAA (0.01,0.05, 0.1, 0.5 mg/L) in combination with BA(3, 5, 10 mg/L)for shoot regeneration. In medium with 5 mg/L of BA and 0.01 mg/L of NAA, adventitious shoot regeneration rate was higher than others treated. The optimal results were observed using MS medium supplemented with 30 g/L sorbitol as carbon source on regeneration system. Sorbitol is considered better carbon source than sucrose for shoot regeneration of pear (P. pyrifolia cv. Niitaka). In order to increase of shoot regeneration in pear (P. pyrifolia cv. Niitaka), plant agar and Daishin agar used as gelling agents, Daishin agar is more efficient in shoot regeneration.

Efficient regeneration methods and transformation system are a priority for successful application of genetic engineering to vegetative propagated plants such as grape (Vitis labrusca L.). This research is to establish shoot regeneration system from plant explants for ‘Campbell Early’, ‘Tamnara’, ‘Heukgoosul’, ‘Heukbosek’ using two types of plant growth regulators supplemented to medium. The highest adventitious shoot regeneration rate of 5% was achieved on a medium containing of Murashige and Skoog (MS) inorganic salts and Linsmaier and Skoog (LS) vitamins, 2 mg/L of TDZ and 0.1 mg/L of IBA. Leaf tissue of ‘Campbell Early’, was co-cultivated with Agrobacterium strains, LBA4404 containing the vector pBI121 carrying with CaMV 35S promoter, gus gene as reporter gene and resistance to kanamycin as selective agent, the other Agrobacterium strains, GV3101 containing the vector pB7 WG2D carrying with mPAP1-D gene. mPAP1-D is a regulatory genes of the anthocyanin biosynthetic pathway. ‘Campbell Early’ harboring mPAP1-D gene was readily able to be selected by red color due to anthocyanin accumulation in the transformed shoot. These results might be helpful for further studies to enhance the transformation efficiency in grape.
