  • br Introduction For a healthy and productive life


    Introduction For a healthy and productive life, good sleep is essential, which has prompted studies on how comfortable sleep can be achieved (Ishiguro et al., 2006). For comfortable sleep, it is very important to create an indoor thermal environment, which could still be improved. Understanding the relationship between thermal environment, physiological responses such as skin and core temperatures, and psychological responses such as thermal and sleep sensations is necessary for identifying the most suitable thermal environment for sleep. As an energy-saving and practical method for creating the most appropriate thermal environment for sleep, local heating or cooling is sometimes used, taking into consideration the differences in local thermal responses. Several studies on thermal comfort during waking hours have been conducted (Fanger, 1970; Kubota et al., 1988; Mori et al., 2003). However, only a few studies have examined the differences in the thermal sensation during sleep (Zhang, 2003); therefore, sufficient information for designing an ideal sleep environment has not been obtained. We performed this study on the basis of sleep experiments conducted under local body heating or cooling conditions to identify the most effective thermal environment for inducing comfortable sleep by identifying the physiological responses during sleep. We also used a human thermal model that can be applied for predicting physiological responses.

    Findings about communication in room use
    Conclusion In this paper, the authors identified which rooms the father and child tended to stay in together and talk, and which rooms they stayed in separately using Active RFID devices and an audio recorder. The reasons they stayed there were obtained by conducting short interviews. The findings are as follows:

    Introduction Built on the highland on the southern slope of Dragon Head Tableland, Hanyuan Hall was not only high and spacious, but also commanded an open and wide view. Due to its large altitude difference, its superstructure was built on three large platforms. The hall has 11 rooms, each of which is 5.35m wide and 28.1m deep, with a pillar diameter of about 0.7m. In addition, Qifeng Pavilion and Xiangluan Pavilion were built 30m to the east and the west of the main hall respectively. The hall and the pavilions were connected by a zigzagging veranda with buildings built around the corners. In addition, an eastern court and western court were built in the southeast and southwest of Yuanxia Hall. Officials had to go to court meetings by following the Dragon Tail Path in front of the hall.
    Project background
    The status quo of surroundings before site protection To the north of this site is farmland, and further north is the original base site of Taiye Pond. To the south of the hall is the residential area of the Xi\'an Railway Bureau. To the east and the west of this hall are also residential areas, and to their north is cultivated land. The present site of Hanyuan Hall is 230m from east to west and 250m from south to north. It is encircled by a wall. The remnants of Linde Hall chiefly include the rammed earth platforms of Linde Hall, Yuyi Building, Jielin Building and the two pavilions. In 1986, protective maintenance was performed on the platform of Linde Hall. The outcropped vertical wall of the front hall and the surface of the first layer of the platform were surrounded by bricks and stones. The outcropped part of the second layer of the platform was covered with 300cm of earth for protection. The rear half of the outcropped part was simply refilled, with an insufficiently distinct boundary. The hall base of rammed earth which was not surrounded by bricks had been seriously damaged and weathered, with the hall surface covered with a thin layer of earth. As a result, the turf and root system had injured the remains, and the problems of water seepage and freeze thawing have not yet been solved. On the bottom of the other platforms of rammed earth, there are traces of surrounding bricks. At some places they reach a height of 1.8m, from which their contracture and curve arc can be seen.
