Development of a dental three-dimensional laser scanning system and measure the accuracy of new adjustable upper and lower dental impression tray was performed. The master model and the duplicated casts were digitized using an dental scanning system. The distance between the reference points were measured and analyzed on the graphic image of 3D graphic software of CATIA. The statistical significance of the differences between the groups was determined by a two-way ANOVA. There were no significant differences between the accuracies of the adjustable stock tray and the master model except only anterior arch width on the upper and lower arch. The adjustable upper and lower stock tray showed clinically acceptable accuracies of the study cast produced by them.

The aim of these studies are to provide a basic data for the development of high-efficiency environmental improvement system that can parallel the cage(henhouse) and hot and cold potable water supply for increased summer heat stress relief and winter feed efficiency by optimal design. The cage area is 273m2. The air-to-water heat pump with 20RT capacity was used for heating and cooling. The control was used as an electric hot water boiler. For calculating heating load determined the cage size, materials, heat pump capacity, heating capacity, heat storage tank, and drinking water tank capacity etc. Therefore the capacity of heat pump was set-up using 20RT. The cage was built as a prefabricated panels henhouse of 13×21×4.5 m (width×depth×height). The heat storage tank and was drinking water tank capacity was constructed 3tons and 10 tons, respectively. In future, it is thought that optimal design considering the cage size and hen breeding scale is required.
