The purpose of this experimental study examine characteristics of blood pigments removal of butchery wastewater by heat processed eggshell, compare activated carbon with its efficiency. Calcined eggshell were classified into four kinds of mesh as HPES-32(Heat Processed Eggshell 32 $mesh=500{\mu}m$), HPES-48($300{\mu}m$), HPES-150($180{\mu}m$) and HPES-150($106{\mu}m$). And two contacting process of CMFA(Complete Mixing Float Adsorption) and FLFA(Fixing layer Flow Adsorption) Were used for getting removal efficiency of blood pigments. In case of using CMFA process, the removal efficiency of blood pigments was occurred as HPES-80>HPES-150>HPES-32, but in case of using FLFA process was occurred as HPES-150>HPES-80>HPES-48>HPES-32. The two results between CMFA and FLFA were differ in strength of removal efficiency of blood pigments.

In the ubiquitous environment, there has been a problem of transmitting data from various sensors at a long distance. Especially, in the process of integrating data arriving at different locations, data having different property values of data or having some loss in data had to be processed. This paper present a method to analyze such data. The core of this method is to define an objective function suitable for the problem and to develop an algorithm that can optimize this objective function. The objective function is used by modifying the OCS function. MFA (Mean Field Annealing), which was able to process only binary data, is extended to be applicable to fields with continuous values. It is called CMFA and used as an optimization algorithm.
