The performance of electric boiler using thick-film heater has been investigated experimentally. Electric boilers are using thick film heater is composed of four to a water chamber. In this study, the water flow rate while changing then umber of heaters and heating performance was evaluated. One water chamber, the average heat release is approximately 6.63kW. And average heat release of four water chamber is about 29.08kW. The energy efficiency of the water chamber 4 was 95.4%. Finally, the average heat release and energy-efficiency of electric boiler is increased with increasing water chamber number.

Since 2003, policies and practices related to the reduction of CO2 gas emission from ships has been discussing by the International Maritime Organization. The representative emission index and indicator are the EEDI (Energy Efficiency Design Index) for the new ships and EEOI (Energy Efficiency Operational Indicator) during the voyage. In this paper a water tank test and procedure development are introduced for the purpose of improving EEDI. The results showed good agreement explaining the characteristics properly.

Recent experimental researches supports the hypothesis that mechanical stimuli play a role in regulating specialized molecules expression in articular cartilage in vitro and in vivo. Therefore we are studying bioreactor to provide a stimulus of mimicked real knee environment. Our bioreactor system consists of a joint motion stimulation device and culture chamber. We fabricated a stimulation system similar to movement of the CPM(Continuous Passive Motion) device for human joint motion. This system is composed of a linear stage, ball spline and links. Also we fabricated a culture system for media and circulation and mimicked knee environment. However, Previous culture system has some problems that media leakage and interference of joint model. In this study, we improved a new-chamber system for non-interference of joint model and medium sealing. Then, this system could be used to investigate the effect of dynamic culture.

The performance of spray vale using three nozzles has been investigated experimentally. Experimental apparatus is composed of the steam line and water line. Capacity 20kW electric heaters were used to produce the 1l0oC steam. The 300C water was produced using a water bath. Water outlet temperature is measured for each model to evaluate the performance of the nozzle.
