In this study, environmental new feeding and management system that are suitable for hot and cool water supply and floor heating system was developed and analyzed the effect for productivity and meat quality with supplying hot water in winter, the results were as follow as. HWSS was not affecting improvement with broiler productivity in initial time. Supplying hot water made the temperature inside broiler barn not go down rapidly as time went by from former term to latter term and continuous supplying hot water made boiler be adapted properly to the temperature and humidity of breeding environment that was requiring at its own growth phases. With unsaturated fatty acid / saturated fatty acids, HWSS was higher in broiler breast but CWSS was higher in the leg. With AST, ALT in blood, HWSS is higher than CWSS but with neutral lipid, protein, glucose, albumin, cholesterol, HWSS is higher than CWSS. Water circulation heating system gave an impact on meat quality and PH showed a higher in CWSS system. Also, redness and yellowness of the meat color was confirmed to be greater in HWSS. It was proved that the temperature difference of drinking water affected farm productivity, the blood and flesh quality, therefore, that could be estimated to be utilized successfully, if that should be used appropriately for productivity improvement according to the week-old of growth phase.

A system has been developed to reduce fluctuation of the indoor temperature in a radiant floor heating system. The system we developed and implemented is called BoilerMan. With the BoilerMan system the hot water circulation pump is controlled by computer software which implements a unique strategy. To minimize the system development time a user-friendly development environment was used. This development environment was useful in the implementation and testing of the efficiency of our strategy. The environment also serves as an easy means for system maintenance. The BoilerMan went through a few test runs against a real apartment house and the result showed significant reductions in the initial temperature overshoots against the target values. It also reduced the operatingtime of the hot water circulation pump. Such positive results were possible due to our unique strategy that exploits heating efficiency information collected from the past run of the very same system. Since the strategy was implemented with embedded software, it makes the BoilerMan flexible, too.

When processing with wood floor covering on wet ondol floor, there are frequent defects caused by floor condensation, floor loosening, lowering of adhesiveness, wood contraction and swelling. The working method is still conventional with problems of lower indoor heating efficiency. Accordingly, ordinary wood floor covering is too expensive without any special functions or features, and it is necessary to suggest reasonable solutions or methods.
