[Method] In the process of feeding,the same broiler house in the same farm was chosen to determine indoor ambient temperature,humidity and air quality at 3-6 weeks age of broilers in different seasons. The measure points were distributed in four different positions in the house. [Result] There was no significant difference in ambient temperature between autumn and winter( P > 0. 05). The ambient temperature in the house in winter was slightly higher than that in autumn. The humidity in autumn was significantly higher than that in winter( P < 0. 05). The temperature and humidity in two seasons could meet the requirements of broiler growth. There was no significant difference( P > 0. 05) in ammonia concentration between autumn and winter,while ammonia concentration in winter was slightly higher than that in autumn. The carbon dioxide concentration of broiler house in winter was significantly higher than that in autumn( P < 0. 05).The total number of airborne bacteria in winter was significantly higher than that in autumn( P < 0. 05). [Conclusion]The indoor temperature kept constant in autumn and winter seasons in closed poultry house. In winter,the humidity was reduced,the carbon dioxide concentration was increased,and the total number of bacteria in the air was increased. The ventilation in winter should be increased in case of heat preservation.展开更多

These houses spread to other areas through Central Java and the Yogyakarta Province of Indonesia. Given the local characteristics, the architecture of these structures is not merely identical in some aspects but is also based on the people and the natural environment. This study examines how environmental synchronization related to vernacular sustainability can be achieved based on the regional diversity between Joglo and Limasan in Centrat Java for contemporary custom. The architectural features of form, size, orientation, materials, and openings from samples of 10 areas in rural Central Java are compared to discover their distinctive sustainability methods. This study aims to prove the capability of the Javanese to synchronize their house in various ways. The reasons behind such synchronization are explored from both natural and social aspects to gain an enhanced understanding of the disparity in vernacular architecture in relation with the environment. Results indicate that within the same category, houses in each area show their indigenous architecture as result of synchronization with the local nature and the social circumstances of the people.展开更多

The measurement investigation to demonstrate the actual situation of the environmental vibration was carried out for several years. The measurement manual for each vibration source such as operations of factory machine, construction works, road traffics and railways to unify measurement methods was made at the start. From the measurement investigation, the vibration amplification characteristics of the detached house by one-third octave frequency in Japan was analyzed as a purpose to improve estimated precision of the vibration in a detached house. In this paper, the vibration amplification characteristic expressed at onethird octave band frequency was shown, and the characteristics was arranged about a result measured with 27 detached houses in Japan.展开更多
