최근 친환경적이고 에너지 효율이 우수한 LED 조명에 대한 관심이 증가함에 따라 현재 학교 조명으로 사용하고 있는 형광등을 대체하고 있다. 형광등은 점멸빈도가 높으면 수명이 단축되며 상황에 따라 조명 환경을 동적으로 재구성하기에 용이하지 않은 단점을 가진 조명장치이다. 이와 달리 LED는 광원의 다양한 조합을 통해 정밀한 제어가 가능하여 상황에 따라 적합한 조명 환경을 제공함으로써 재실자의 시각적 쾌적성 및 작업 능률 향상 등의 효과를 가져온다. 본 논문에서는 교실 환경을 대상으로 요일 및 시간, 교과목 종류 등의 스케쥴 정보와 교사의 위치 및 행위를 기반으로 각 상황에 적합한 최적의 조명 환경을 제공하여 학습 능률을 향상시키기 위한 상황인지기반의 LED조명제어시스템을 개발한다. 제안한 시스템의 성능 평가를 위해 교실 환경 테스트베드를 구축하고 조명 환경 지표를 이용하여 교실 내 조명장치의 색온도, 조도를 제어한다.

This paper provides an outline of mathematics education based on the classroom ecology. Ecology is the subject that concentrates on the relations of human and environment. As mathematics education consists of many factors, it is natural that mathematics education should be interest in the perspective of ecology. This paper examines the meaning of ecology and classroom ecology of mathematics education in the perspective of ecology. And it provides the directions of ecological mathematics education. In special, I set the frame of mathematics classroom in the perspective of ecology. The ecological structure divides microsystem(teacher, student, content), mesosysten(relations of microsystems), exosystem(school), and macrosystem(the objects of mathematics education). Lastly, I suggest the ways of mathematical learning and research of classroom ecology in mathematics education. For we should focus the improvement of students' mathematical ability, we must search for the various teaching and learning methods and the ares of research in the perspective of ecology classroom. Therefore, we should be interested in the classroom environments as well as teaching methods, contents based on the ecology classroom in mathematics education.

In the near future, we can access information which we want, whenever we want, wherever we use. Because almost devices in ubiquitous environment are connected by either wired or wireless network. Especially, u-Learning emphasizing on pedagogical property is enable to improve learning abilities. As researches of the previous u-Learning. there have been learning by mobile devices such like PDAs as well as the smart classroom, which makes the remote students participate in the existing class. However, these researches have not satisfied pedagogical, cooperative and ubiquitous properties yet. Thus we suggest the framework for both local and mobile classroom, which can make the properties easy to satisfy.

This study utilized the What Is Happening In this Class (WIHIC) questionnaire to examine students' perceptions of their science learning environment. Data was collected from 587 middle school students in seven coeducation schools in Seoul. Higher mean scores occurred on the scales of Student cohesiveness, Task orientation, Cooperation and Equity in the WIHIC, whereas lower mean scores occurred on Teacher support, Involvement and Investigation. The effects of gender on students' perceptions of their science learning environment were not statistically significant overall, but girls perceived Student cohesiveness and Cooperation more positively than boys. Correlations between the WIHIC scales of the low-level group that perceived their learning environments negatively (10 percentiles) and the high-level group that perceived their learning environments positively (90 percentiles) were computed. Teacher support, Involvement, Task Orientation and Investigation were highly correlated with each other in the low-level group, whereas only Teacher support and Equity were correlated in the high group. Educational implications were discussed.

현대인은 대부분 시간을 보내는 노동 환경에 의해 영향을 받는다. 이에 따른 정신적, 신체적 질환은 개인의 건강 문제를 넘어 삶의 질과 연결되며, 결국 사회문제로 귀결된다. 대한민국은 여전히 '산재 공화국'이라는 오명에서 벗어나지 못하고 있는 듯 보이지만, 분명한 것은 끊임없는 성토와 연구를 통해 꾸준히 개선되고 있다는 점이다. 그 중심에서 근로자들과 함께 더 나은 사회를 만들기 위해 노력하는 곳, 한양대학교 의과대학 직업환경의학교실이다.

제7차 교육과정은 선택과목을 확대하고 수준별 수업을 유도하고 있다. 이러한 방식에 따르면 중고등학생들이 대학에서처럼 자신이 수강신청한 과목에 따라 교실간에 이동하게 된다. 학교당국과 학생들이 기존 교실 환경내에서 이러한 교육적 변화를 적극적으로 수용할 수 있도록 소프트웨어적인 보조가 필요하다. 이를 위해 본 연구에서는 시간표 작성 , 시설 배치도 작성, 교실 배정, 교실 위치 및 시간표 보기, 그리고 민감도 분석을 위한 통합 시스템을 제안한다.

The purpose of this study is to investigate development direction of a mathematics subject classroom. This study started with an analysis of previously conducted studies to investigate. After that, I selected and visited eight schools thatapplied the Mathematics subject classroom for interviews. Observations and interviews with math teachers were executed to figure out circumstances and operational status of the mathematics subject classroom. As the result of this research, the Mathematics subject classroom required various improvements in the facilities and the curriculum systems. Throughout this study, Isuggestedfive principles for teaching and learning. These principles are Creativity, Communication, Cooperation, Mathematical thinking and Problem solving. Furthermore, two subject classroom models for teaching and learning of mathematics - the cooperative learning room and the media room - were designed. These room required different resources and served distinct function.

The basic unit of school is a classroom and the aural environment of the classrooms is essential factor for education purposes. Therefore, many efforts have been undertaken for enhancing the acoustical performance of the classrooms in many countries. As a result, acoustic criteria including reverberation time and background noise level have been established in US and UK for school classrooms depending on the usage and size of the rooms. However, in Korea, there has been little researches concerning the room acoustical investigations of the classrooms. The present study investigates the current situation of the aural environment of the 15 classrooms in Korea including elementary, middle and high schools. The acoustic criteria measured include RT, $D_{50}$, STI, SNR and background noise level. As the results, it was found that the background noise levels of the schools adjacent to roads exceed the US and UK standard of 35 dB(A). Also, most schools have so low SNR that they may be interfered by noise, which may affect speech transmission. It was also revealed that some schools have longer RT than the US standard of 0.6 s, but they all have high speech intelligibility.

학교 교육의 특성상 많은 부분이 교실에서의 음성정보 전달에 의해 이루어지고 있는 점을 감안하면 바람직한 청취환경의 개선이 검토되어야 한다. 또한 중${\cdot}$ 고등학교의 수학능력시험의 국어, 영어 듣기평가 및 다양한 어학 시험이 시청각 시설을 통해 이루어지고 있는 실정이므로 교실의 음환경은 매우 중요한 요소라하겠다. 본 논문에서는 음환경을 좌우하는 음원의 위치에 따라 명료 도가 어떻게 달라지는지를 실험을 통하여 검증하고, 명료도가 높고, 교실 전체에 균등한 분포를 보이는 음원의 위치를 찾아내고자 하였다. 교실 내의 음원의 위치로는 일반적으로 많이 쓰이고 있는 column(벽면 노출형)과 ceiling(천정 매입형) 위치와 임의의 음원 cluster(전면 중앙)를 선정하여 음장 파라메터를 측정한 결과 RASTI 는 세 타입 모두 $0.54\~0.55$로 값으로 근소한 차이를 보이고 있으며, 잔향시간은 ceiling>cluster>column의 순서로 나타났다. 일반적으로 잔향과 명료도와의 관계는 반비례하는 것으로 알려져 있으나, 실험 결과 잔향시간이 1.33초로 가장 긴 column 스피커의 경우 D50 값이 약 $47\%$로 가장 높은 값으로 나타났다. 이것은 column형 스피커의 경우 음원과 각 학생의 위치에 대한 평균 직접음선거리가 가장 짧기 때문인 것으로 나타났다.

The purpose of this study is to derive a curriculum environment for operating various student-centered teaching and learning methods, and the following results were derived: First, most of the lectures, discussions and consultations, data search, report preparation, presentation, work exhibition, and others were commonly derived, regardless of the types of long-term and short-term project classes for each subject. In particular, the necessity of operating various classes at the same time was suggested, indicating the need for an integrated teaching and learning operation environment in the unit subject class. Second, considering that practical classes are linked concurrently to lectures and discussion classes to conduct one subject class, it is necessary to switch to a specialized curriculum system that allows various classes such as lectures to be carried out at the same time. Third, as a result of grasping the appropriateness of the space size of the subject class for realizing different class types in the future, it can be seen that the space size of the practice room, including the space for practice and the area for exhibition, should be expanded. Based on the research results, the spatial environment for the operation of future teaching and learning classes is based on the public curriculum classroom system, and whether professional curriculum classes, such as lecture rooms and discussion and presentation rooms, are secured according to the number of students.
