<p>We recorded avifauna by listening to live sound broadcasts from Furano, Hokkaido; Chichibu, Saitama; Yamanakako, Yamanashi; and Shiga Kogen, Nagano Prefectures during three months of the breeding season from 2012 to 2024. Of the 81 major bird species, 65 showed no significant trend of increase or decrease. On the other hand, 11 species, such as Varied Tit <i>Sittiparus varius</i> and Eastern Crowned-warbler <i>Phylloscopus coronatus</i>, increased significantly, and five species, such as Japanese Tit <i>Parus cinereus</i>, decreased significantly. In Chichibu, the Community Temperature Index increased over the 12 years, indicating a change to the bird community of a warmer region, while other sites showed no significant changes. Other studies have also shown an increase in the species richness of mainly broad-leaved forests, such as Varied Tit and White-eye <i>Zosterops japonicus</i>, at study sites in central Honshu at elevations similar to Chichibu, suggesting that a significant change in avifauna is currently occurring at elevations about 1000 m in central Honshu.</p>

At PLATEAU, 3D city models are being developed, utilized, and converted into open data, but the parks and green spaces are treated as aerial images without height. Japanese gardens are highly regarded around the world as Japan beauty, so it must be beautiful even in 3D models, but garden stones have complex shapes and surface and each stone is one and only, so realistic 3D modeling has not yet developed and has not been widely used. In this study, we used a handy laser scanner used in reverse engineering to test the creation of a 3D model of garden stones with an accuracy of less than a millimeter. For measurement, a gap of 52 cm around the object is required. Garden stones installed in gardens are often not able to remove measurement obstacles, so the parts that can be measured are limited, but they can be used for 3D modeling of Japanese gardens. In addition, if it is a garden stone as a garden material, it was possible to create a 3D model of the entire circumference of the stone by turning it over from top to bottom. It was suggested that a 3D model of the garden stone could be used as an online catalog for garden stone sales.

BACKGROUND: Natural sounds are reportedly restorative, but most research has used one-off experiments conducted in artificial conditions. Research based on field experiments is still in its infancy. This study aimed to generate hypotheses on the restorative effects of listening to natural sounds on surgeons, representing professionals working in stressful conditions. METHODS: Each of four surgeons (two experts and two residents) participated six times in an experiment where they took a 10-min break listening to natural sounds (four times) or without natural sounds (twice) after a surgical operation. We measured their skin conductance level, an indicator of sympathetic arousal, continuously during the break (measurement occasions N = 2520) and assessed their mood using two questionnaires before and after the break (N = 69 and N = 42). We also interviewed them after the break. RESULTS: Based on statistical Linear Mixed-Effects modeling, we developed two hypotheses for further, more detailed studies: (H1) Listening to natural sounds after an operation improves surgeons' mood. (H2) Inexperienced surgeons' tension persists so long that the effect of natural sounds on their sympathetic arousal is negligible. CONCLUSIONS: This risk-free, easy-to-use means of stress alleviation through natural sounds could benefit highly-stressed people working indoors.
