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 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.

We proposed a new method using the spatial average of the one-dimensional distribution inside and outside the room as a method for spatial evaluation of the electromagnetic shielding room and obtained the following three findings through actual measurement and analysis.

First, it is simpler and more reproducible than conventional methods. Second, the one-dimensional spatial average of the outdoor space can represent the outer space. Third, the one-dimensional spatial average in the room does not depend on the directivity of the transmitting antenna, the installation method, and the position and orientation of the measurement line.

The hygienic environment of accommodations in Japan is now deteriorating owing to the rapid increase in private lodgings. Thus, the purpose of this study was to investigate their hygiene status.

Hotels showed good hygienic environments, whereas private lodgings had hygienic problems. Most of the private lodgings d id not install a mechanical ventilation system, and in some cases, CO₂ concentrations exceeded 1000 ppm during the stay. Accommodations with cooking space and absence of manager revealed to have higher risks of contamination. Therefore, standardizing management methods and increasing management awareness leads to lower risks of contamination.
