국제 바칼로레아 초등교사교육 프로그램의 개발 연구

김영민 대구교육대학교 초등교육연구소 2021 초등교육연구논총 Vol.37 No.4

본 연구의 목적은 국제 바칼로레아(IB) 교육을 계획, 실행 그리고 성찰할 수 있는 교사 역량 을 길러주기 위해 대학원 과정의 초등교사교육 프로그램을 설계하는 것이었다1). 이를 위해 해 외의 IB 교사교육 프로그램을 분석하였으며, IB 후보학교의 교사를 대상으로 설문 조사를 실 시하여 프로그램의 내용 구성과 운영 방안에 대한 요구도를 분석하였다. 결론은 다음과 같다. 첫째, 대학원 과정의 교과목에 대한 요구도 분석 결과 선호도가 높은 ‘교육과정’, ‘탐구중심의 교수·학습’, ‘학습과 평가’를 필수 과목으로 정하고, ‘수업관찰, 분석 및 성찰’, ‘교육실습’ 을 현 장연구 및 실습과목으로, 나머지 6개 과목을 선택 과목으로 하는 교육과정이 구성될 수 있다. 둘째, 수업 방식에서는 수업 내용의 이해와 활발한 상호작용, 즉각적인 피드백 등의 장점이 있는 대면 수업을 원칙으로 하되, 효율성의 측면에서 비대면 수업도 병행하는 것이 선호되었 다. 또한, 계절제 수업보다는 야간제 수업이 선호되었는데 수업 후 현장 적용과 성찰의 과정이 필요하다는 의견이 많았다. 셋째, 교수 언어에서는 한국어와 영어를 혼용하는 방식이 선호되었으며, 다음으로 한국어 강 의, 영어 강의 순이었다. IB 문서를 이해하고 전 세계의 IB 월드스쿨 교사들과 소통하는 데 따른 영어 사용의 필요성을 느끼면서도 영어에 대한 부담도 크게 느끼는 것으로 나타나 이에 대한 적극적인 지원이 필요할 것이다. 마지막으로 현장과 연계한 교육실습 기간으로 4주 이하가 적절하다고 응답했으며 졸업에 필 요한 요건으로 논문 대신 프로젝트, 현장연구 등에 대한 선호도가 높아 이를 반영하는 것이 필 요하다. The purpose of this study is to design a teacher training program for IB(International Baccalaureate) PYP(Primary Years Programme) school teachers. Recently, IB education has been actively researched recently to be more in corformity with the core elements of 2015 revised Korean national curriculum: learner-centered, competency-based, and inquiry-based. As of 2021, two IB world schools and five candidate schools run PYP programs in Daegu, Korea. Teacher education is urgent as IB schools are expected to continue to increase in the future. To develop a teacher education program in connection with the graduate school master’s degree, the curricula of IBEC(IB Educator Certificate) institutions were analyzed and a survey for IB PYP school teachers was conducted. Based on the survey results, 3 mandatory courses, 6 elective courses and 2 field research and practice courses were suggested as the curriculum of the graduate program. In addition, efficient ways for the actual operation of the program were also suggested.

In-Situ 분석법에 의한 연료전지 특성 연구

PEMFC stack power output is needed to be around 100 kW to meet the requirements of automotive application and scaling-up the active area of the stack cells will allow a higher power. In the case of scaling-up the active area of cells, it is difficult to obtain uniform in-plane internal conditions such as temperature, relative humidity and stoichiometry of the feed gas. These ununiformity with the location in the cell would affect both the performance and durability of the stack, so it is important to understand phenomena in the cell for improving them. In this study, the current density, electrochemical resistance and performance distribution measurement was performed to understand the ununiformity in a single cell using in-situ method; (1) Current Density Distribution (CDD) Device and (2) Segmented Cell Fixture. The influence of location of feed gas on the performance of a single cell was experimentally measured and discussed by using a segmented single cell which was composed of 8 compartments. The correlation between the location and performance in a single cell was discussed by these two tools and it was extended between the local characterization and the durability in a MEA by comparing the used cell with a fresh one. It was also studied in terms of electrochemistry by Electrochemical Impedance Spectroscopy.

It is difficult to apply commercial power to a sensor system for diagnosing the safety of railroad facilities in a railroad operating environment. Therefore, the measurement system is configured using the solar system and the battery. In the case of the existing solar controller, the battery voltage is applied to the solar panel when sunlight is not secured, and the battery operation time is relatively reduced. Battery usage efficiency was improved by improving the solar system, and it was verified through testing.

Purpose: The purpose of this study was to explore the empowerment experience of persons with developmental disabilities who act as partner instructors in the field of education to improve awareness of persons with disabilities in the workplace. Methods: Research participants selected four partner instructors with developmental disabilities, conducted in-depth interviews, and analyzed them using a phenomenological method. Results: People with developmental disabilities experienced positive empowerment in the training partner instructor activities to improve awareness of the disabled in the workplace. The opportunity to start the lecturer activity started with the recommendation and provision of information from the surroundings, and as a result, it was shown that he was practicing an independent and active life as a member of society. As a person with a developmental disability, based on positive understanding and acceptance of disability issues, they were actively interacting inside and outside the community. As a result of this study, the experience of empowerment of partner instructors with developmental disabilities was found to be 'the process of gaining strength by oneself', 'self-directed life in relationships', and 'influence in society'. Such research results show the reality of 'empowerment by persons with developmental disabilities' by adhering to the perspective of persons with developmental disabilities, confirming that persons with developmental disabilities can acquire power on their own, and presenting the practice of empowerment by persons with developmental disabilities Could.

Purpose : The purpose of this study is to empirically analyze the impact of innovation and facilitating condition of logistics 4.0 technology on logistics safety participation and safety performance for logistics companies. Research design, data and methodology : Based on previous studies related to logistics 4.0 and logistics safety, measurements for each variable were derived, and a survey was conducted on employees of logistics companies. Also exploratory factor analysis, reliability analysis, correlation analysis, and regression analysis were conducted. Results : The innovation and facilitating condition of logistics 4.0 technology had a significant impact on logistics safety participation, and the facilitating condition of logistics 4.0 technology had a meaningful impact on safety performance, but innovation did not. In addition, logistics safety participation had a significant effect on safety performance. Conclusions : Logistics companies need to induce participation in logistics safety by actively introducing and utilizing logistics 4.0 technology, thereby prevent the occurrence of safety accidents.

Pyrolysis properties and kinetics of mandarin peel

김영민,박영권,이형원,이시훈,김성수,박성훈,전종기,김승도 한국화학공학회 2011 Korean Journal of Chemical Engineering Vol.28 No.10

−The thermal property of the pyrolysis reaction of mandarin peel was studied using thermogravimetric analysis (TGA). Thermogravimetric analyses with temperature increases of 10, 20 and 40 ℃/min showed large weight losses within the temperature range 150-590 ℃. Differential thermogravimetric (DTG) analysis curves illustrated that the pyrolysis of mandarin peel was a multi-step process, consisting of water desorption, the decomposition of pectin, hemicellulose,cellulose and lignin, and devolatilization of the residual char. The apparent activation energies ranged between 119 and 406 kJ/mol, depending on the pyrolytic conversion. The pyrolysis products were analyzed, using pyrolyzergas chromatography/mass spectrometry (Py-GC/MS), to evaluate mandarin peel as a renewable source of valuable industrial chemicals. The pyrolysis products of mandarin peel contained high portions of methanol and acetic acid,as well as valuable compounds, such as limonene and vitamin E.
