영문 초록

Illumination, brightness, and glare of a blackboard negatively affect on studying efficiency of an evening class. This thesis is about the relation between illumination and brightness of a blackboard in the evening class. Illumination and brightness of the classroom blackboard surface being looked at from each seat were measured. Based on the measured results, the relation between levels of illumination and brightness were analyzed in detail. The illumination is the highest at the center of the blackboard, and it gets lower and lower as being far from it. At the first and second row of the classroom, the brightness is maximum at the top of the blackboard, and the center-top has the maximum brightness point after the third row. In addition, the bottom of blackboard has the minimum brightness from a diagonal view. The ratio of the maximum blackboard brightness to the minimum one is approximately 1.5. As a consequence, students in the evening take the influence of glare from the classroom lighting. Also the degree of the influence is not equal at all the seats, but depend on the specific location. Therefore, the illumination of evening class should secure sufficient intensity of illumination on the desk surface, and prevent students and teachers from direct rays of the light by using the blackboard that has curved surface. Such environmental improvements can be fulfilled by adopting various ways of apparatus arrangements, buried illumination, louver-ceiling illumination, and other methods in behalf of students academic efficiency and their eye protection.
