This experiment was carried out to establish effective egg powder preparing method by studying the denaturation of egg protein and changes of functional properties of egg powder at different predrying pH levels. The results obtained were summarized as follow; 1. As the predrying pH rises, whipping quality, whipping stability and heat coagulation capacity of egg white powder were enhanced, so also were the emulsion capacity and emulsion stability of egg yolk powder. 2. On DEAE-Cellulose column chromatography, egg white protein was fractionated into five peaks. And on the acrylamide gel electrophoresis egg white protein was separated into eleven bands and globulin protein was sensitive to the low predrying pH.

Asymmetrical and unbalanced features such as rotor blade of helicopter, actuator of hard-disk in personal computer are usually manufactured with composite materials. In this case, mass distributions and center of gravity of the parts are important because of their static balancing. Therefore in the manufacturing processes, it is needed to check out the exact data of weight and gravity center. In this study, it has been studied experimentally the balancing of laminated rotor blade by using multiple-point weighing method and lab-view system.

Recently, the cases of using bonded dissimiliar materials whose components are different each other, tend to increase for the purpose of using to developement of new materials and special objects in the field of industry in these days. Among the cases the strength evaluation of the joining materials of vehicle engine and structural materials of heat engine are bonded joint ceramics/metal.<br/> In this paper, strength evaluation method of ceramic/metals considering stress singularity were analyzed using boundary element method and 4-point bending test So the advanced method of quantitative strength evaluation for ceramic/metals bonded joints are to be suggested.<br/>
