Ubiquitous Computing is proposing the vision for future architecture and space, and need application in multilateral side. Each field may have to flow expert analysis of Ubiquitous Computing under proposition called Ubiquitous environment construction. Confrontation about these phenomena is required in the field of architecture. Method that can utilized Ubiquitous Computing in present space is from concept through unfolding direction of technical development and partial example. Purpose of this research is to present methodology of space plan that is optimized by Ubiquitous Computing based on elements that is analogized from Ubiquitous Computing's principles.

Three properties of food waste are water 80%, ash 3%, volatile matter 17%. When food waste goes through treatment process such as removal of foreign substances, removal of water as well as sodium, dryness, and pulverization, it transforms into 4,000Kcal/kg purverized fuel if moisture content is below 13%. Fuel ratio(fixed carbon/volatile matter) of purverized fuel is low compared with bituminuous coal. Ignition temperature measured by thermogravimetry analyzer is about 460?C. Combustion test of purverized fuel have been performed using energy recovery facility which include storage tank of dewatered cake, dryer, hammer mill, combuster including burner, boiler, flue gas treatment equipment. When 160-180 kg/hr of fuel is steadily supplied to burner for 3 hours, combueter temperature reaches about 1000?C and CO is 77-103ppm at 1.55 excess air ratio and SOx and Cl are under 2ppm and 1ppm, respectively. This experiment demonstrate that purverized fuel made from food waste could be an alternative clean energy for high oil price era

This experiment demonstrate that purverized fuel made from food waste could be an alternative clean energy at the age of high oil price.

Oxidation characteristics of benzene as a VOC was investigated using a fixed bed reactor system over copper base catalysts. The copper base catalysts were made by using copper nitrate reagent and various support materials such as γ-Al₂O₃, TiO₂, and zeolite. The parametric tests were conducted at the reaction temperature range of 200~500℃, benzene concentration of 1,000~2,000 ppm, and space velocity range of 5,000~20,000 hr<sup>-1</sup>. The property analyses such as BET, SEM, XRD and the conversions of catalytic oxidation of VOC were examined. XRD analysis on copper catalysts showed CuO crystal forms and the peak intensity of CuO increased as the impregnation weight of copper grew. The experimental results showed that the conversion was increased with decreasing space velocity. It was also found that Cu/γ-Al₂O₃+TiO₂ catalyst showed the highest activity for the oxidation of benzene and 15% metal loading was the optimum impregnation level.
