In recent years, the number of offices introducing personal comfort systems (PCS) has increased. However, in some offices, the complexity of the PCS operation, caused by sophistication, discourages workers from using the PCS. Considering this background, this study aims to investigate the influence of the PCS operability on their usage rate, thermal environment evaluation and workplace productivity. A measurement survey was conducted with three types of PCS with the same performance but different operational types. As a result, the PCS operability evaluation was significantly correlated with PCS usage rate, thermal environment evaluation and workplace productivity.

The present study examined the impact of an artificial window in an enclosed personalized work environment (PWE) on users’ psychology and productivity through two subject experiments. The results showed that projecting a natural landscape on an artificial window improved the space impression of PWE and ease of work-related activities. However, there was a possibility that people with higher neurotic tendencies were not preferred the artificial window. Additionally, an artificial window in the PWE improved the number of correct answers to a task simulating an online meeting, which was related to psychological improvements such as ease of communication.

The government of Japan has developed a plan to promote cycling in response to recent increase in cyclist. The plan includes the use of a bicycle for tourism and daily transportation on riverside road; however, local governments are mainly responsible for implementing the plan and maintenance of the cycling road. The purpose of this study is to obtain knowledge to help determine a maintenance policy by understanding the impressions of cyclists. Here, we have conducted a field test using the caption evaluation method for the cyclists in tourism and daily transportation on the Kinugawa Cycling Road.

In China, fires with numerous casualties in recent years had led to the development of fire safety codes for elderly nursing homes. The evacuation safety of the subject which conformed to pre-amendment codes was confirmed to be not ensured. To ensure the evacuation safety of the subject, smoke exhaustion systems must be installed in the fire room. In the natural smoke exhaust system, the opening area must be 1/20 of the floor area with an activation remotely or sequenced activation. In this case, the evacuation of the fire floor and the floor below the fire floor are also safe.

In this study, the effects of partition walls on floor vibration were discussed based on analysis and measurement. Vibration measurements before and after removal of partition walls showed significant differences in response and vibration characteristics. The analysis showed that the effects of the partition walls depend on the vibration modes of the upper and lower floors where the partition walls are attached. It was inferred that partition walls have the effects of increasing effective mass due to the mode change and increasing stiffness due to the resistance elements of the floor, depending on the phase of the connected floors.

We have conducted various studies on methods to prevent contact resonances. It was suggested that the proposed method of the previous studies could be used to estimate carpets and building material tatami. On the other hand, there was a problem with the straw tatami. Therefore, in this paper, we conducted an experimental study on an estimation method that is an extension of the proposed method for vertical and horizontal vibration. As a result, it was shown that by considering the proposed modified estimation methods, the error of the contact resonances can be reduced and estimated even with the straw tatami.

The aim of this study is to clarify the effect of the mask wearing in evacuation shelter - analogue setting. A subject experiment was conducted to examine the effects of mask wearing on stress using electrocardiograph and environmental conditions. The subjects completed questionnaires regarding their thermal sensation, comfortability, fatigue, and “perceived difficulty breathing”. As a results, mask wearing increased “perceived difficulty breathing” in the case of hot condition of enthalpy showed higher than 50 kJ/kgDA. In addition, it is found this facilitated an increase in the LF/HF ratio because HF power is decreased with increment of “perceived difficulty breathing”.
