교육시설 내 실내 공간의 정책에 따른 감염관리 효과 분석
이종직,안창범,윤인석,박문서 대한건축학회 2024 대한건축학회논문집 Vol.40 No.5
COVID-19 대응으로 정부는 학교 같은 밀집 지역의 감염 전파 위험을 증가시킬 수 있는 비약물적 중재(NPIs) 및 치료 중심 정책을 도입했다. 이에 따라 시설 일부 폐쇄 및 운영시간 제한과 같은 조치가 시행되어 사회경제적 영향에 대한 우려가 제기되었다. 따라서 본 연구는 학술 기관 내 감염 요인을 식별하고, 보행자 흐름의 시뮬레이션 모델을 개발하며, 질병 전파의 위험 기준을 설정하고 정책 실험 및 영향 분석을 실행하는 것을 목표로 한다. 다양한 중재 방안, 예를 들어 교실 구역화 및 이동 제한 등을 평가하였으며 그 결과 단독으로 실행된 공간적 분할 정책은 효과적이지 않다는 결론을 도출했다. 반면, 자유 이동의 비율을 줄임으로써 접촉 시간과 감염 전파 위험을 유의미하게 감소시킬 수 있다는 것이 확인되었다. 그러나 중재의 효과성은 학생 수 및 밀도에 따라 달라지므로, 학교 규모와 학생 수에 따른 적합한 최적 전략을 도출하기 위한 추가 연구가 필요하다. 또한 학교 및 교육 기관이 감염 관리 정책을 강화하고, 의사결정을 위한 실질적인 지침을 제공하는 데 기여할 수 있다. To address COVID-19 concerns, governments have implemented Non-Pharmacological Interventions (NPIs) and treatment-focused policies,particularly in densely populated areas like schools. These measures, including partial closures and time restrictions, raise concerns aboutsocioeconomic impacts. This investigation aims to identify infection factors in academic settings, develop a pedestrian traffic simulation model,establish risk thresholds for disease spread, and conduct policy experiments and impact analyses. Various intervention methods were assessed,such as classroom zoning and movement restrictions, finding that spatial compartmentalization alone is ineffective. However, limiting freemovement reduces contact time and infection risk. Nonetheless, intervention effectiveness varies based on student population and density,highlighting the need for further research to recommend optimal strategies based on school size and enrollment. This study aims to supportschools and institutions in improving infection control policies and offer practical guidance for decision-making in this area.
Guided Teaching of Reflective Writing Skills in a Korean High School English Class
이종직,정영철 현대영미어문학회 2023 현대영미어문학 Vol.41 No.3
This study aimed to examine the levels of reflection that Korean high school students demonstrated in their English essay writings and investigate the degrees of change in the levels of reflection resulting from teacher intervention. Students’ perceptions towards teacher intervention were also scrutinized. For these research purposes, two English essays from each member of a class of twenty students were analyzed according to van Manen’s (1977) classification. Students’ reflection notes and questionnaire survey responses were also examined in a qualitative way. The results of this study revealed that the proportion of students’ writing categorized as critical reflection was very low, although the levels of their reflection improved through guided teaching with teacher intervention. It was also found that the degrees of acceptance of teacher feedback varied depending on the students’ tendencies and levels of reflection. This study shows that teaching critical writing skills to high school students in Korea is challenging, but their reflective thinking skills can be gradually enhanced through guided teaching.
Korean Secondary Students' Perceptions toward the Cyber Home Learning System-based ELT Contents
이종직,박명수 한국영어교육학회 2012 ENGLISH TEACHING(영어교육) Vol.67 No.1
This paper aims to examine the online learning service called the Cyber Home Learning System (CHLS), which was introduced in 2004 and has been in operation nationwide since 2005. It appears questionable as yet whether the CHLS has obtained a promising outcome. This study, therefore, aims to investigate how many secondary students are currently utilizing the English contents in the CHLS and how they perceive this service. The results of this study indicated that English contents of the CHLS were utilized by only a small number of students, and the contents were rarely perceived as useful. In particular, students perceived that there was little interaction with teachers in cyber space as well as in a classroom setting. Furthermore, five items were identified as the major reasons that hinder students from using the CHLS: lack of promotion; difficulty of self-directed learning; lack of time; low quality; and inconvenience. The results of this study suggest that teachers are influential in affecting students’ perception toward the CHLS, and that it is of paramount importance to renew the CHLS based on the results of a needs analysis.
DeviceNet을 이용한 다이나모미터의 제어 시스템에 관한 연구
이종직(Jong-jik Lee),이용범(Yong-bum Lee),이기천(Gi-Chun Lee) 대한기계학회 2013 대한기계학회 춘추학술대회 Vol.2013 No.12
In this paper, a real-time control algorithm was developed using DeviceNet communication to control rotating power sources such as engine or dynamometer operated for the performance and durability tests of rotating machines. The test equipment which was joined with the algorithm comprised a input dynamometer, test objects (gearbox and transmission), and output dynamometer for torque control. Consequently the test results in this study showed that using DeviceNet communication led to remarkably efficient control.
