A questionnaire survey was conducted in order to study the environmental and social factors which effect office workers' motivation as well as other comprehensive evaluation that are also supposed to influence workers' workplace productivity. As a result, places and behaviors which maintain and/or improve workers' motivation were extracted and compared with the factors of other comprehensive evaluations. It can be explained with larger coefficient of determination that motivation is one of the causal factors of the satisfaction of office environment. It was also found that some environmental factors influenced workers' motivation with the same weight as social factors. Finally the influence of difference of type of the worker was also studied.

This study aims to ascertain the limits to which a solid angle can be used as an indicator for evaluating the senses of physical oppression and of openness in urban spaces. For that, a logistic regression analysis focusing on the street as a whole and the proportion by evaluating value was conducted by evaluating each criterion found through a logistic regression model to assess the limits of the effects of the solid angle. The allowable values for the sense of physical oppression are configured using a threshold if the sense of physical oppression is felt, but reconfiguration of the allowable values for the sense of openness is not necessary. Therefore, for those respondents who indicated that a sense of physical oppression exists, it appears that the limits of that allowable sense of physical oppression are as follows: using judgment of 75% of the evaluators, the rate of solid angles was 76%; using judgment of 50% of the evaluators, the rate of solid angles was 65%; and using judgment of 25% of the evaluators, the rate was 53%. Compared to the studies of the Japan Society of Civil Engineers, Spreiregen and Takei, those allowable values are more appropriate.

&nbsp;Light control systems using motion sensor save energy consumption in office efficiently. It is also known that rapid change of illuminance might cause unpleasantness to workers. To solve this problem several researches studied the relation between workers' perception and the way of dimming of luminaires around workers, however they did not focus the effect of the light source color. Although there are many discussion and doubt, Kruithof curve is a famous theory, that there are pleasant or unpleasant combination of illuminance and color temperature. Here our question arises that workers' perception on the change of illuminance might be influenced by the impression of the combination of illuminance and color temperature before and/or after the fluctuation.<br>&nbsp;Thus, we conducted three experiments in an experimental room, focusing two points. The first was perception of different color temperature in a room with achromatic, that is white wall, and the second was with different color temperature and chromatic wall color. The size of the room is W3.5m x D3.5m x H2.7m. In the achromatic phase, three color temperature, 3000K, 5000K and 6500K were presented by LED luminaires on the ceiling. In the chromatic phase the same three (or two of 3000K and 6500K) color temperature were combined with four wall color, orange, pale orange, blue and pale blue, covering existing white walls with color cloth of 1.5 m height from the floor. In one session of the experiment color temperature and wall color were fixed to one and illuminance was fluctuated several times with different ending level and speed randomly. Starting illuminance was fixed to 750 in this research, and ending illuminance and speed were decided according to the existing research. 20 students participated at every experiments. During the session, participants were doing a task to search about one question with a laptop PC and write down the findings on a paper, and also instructed to fill the questionnaire every time they perceived the change. Dimmed illuminance recovered to the starting level with longer seconds. At the end of the experiment, participants evaluated the pleasantness of the room with each of the all combination of wall color, color temperature and illuminance at the stating/ending time of the change.<br>&nbsp;The results show that with white wall the perception ratio is statistically lower at 5000K than at 6500K. There is some tendancy that the perception ratio is relatively higher when the color of lamp and wall is similar ones, that is, blue wall and 6500 K or orange wall and 3000 K, though this tendency was not found when the color of wall was pale, whitish one.<br>&nbsp;Finally, participants' evaluation of pleasantness on each combination of wall color, color temperature and illuminance before and after the change were compared to the perception ratio of the experiments. It was found that negative subjective impression of the combination before/after the change leads to higher perception and positive impression show the opposite results.

本研究では東日本大震災後の首都圏節電下のオフィスの光環境の実態の記録を残すとともに、そこからオフィス照明の基本要件を抽出し、省エネルギー照明手法の開発を行った。節電によって、照明のエネルギー削減はランプや器具の効率の向上の他に、必要照度を下げる、照射面積を小さくする、照射時間を短くすることによる効果が大きいことが示された。これらは「光環境の質を落とす」と考えられ触れられてこなかった方法である。照明の基本的要件の見直しから着手し、照射面積・時間、昼光利用を考え、人の視覚特性を利用した「不均一・変動照明」による照明手法の提案を行い、これらに基づいた新しい照明基準作成の準備を行った。

This study is on the appropriate setting of the angle of view and reality in computer graphics, as a method of simulation of interior. 1. For the simulation of the room about 1 6 m^2, using 17 inch monitor. 74 degrees is the best horizontal angle of view. 2. We studied what element of space affects the reality of CG and how it affects. We think the CG is real, when the shadow, the smoothness of the curved surface and the texture are real. The detail of modeling, the fineness of mesh, the texture, the times of calculation and the method of rendering affect the reality. But their highest settings don't result in highest reality and we can set the parameters properly. 3. The media we present CG is not so influential on the reality, but it affects the space perception so much.
