Recently, applications of biomass-based plastics have increased according to the eco-friendly policy of the reduction of carbon dioxide emissions in domestic and foreign government. In this study, a paper plastic composite was produced by compounding polypropylene and micronized paper powder that was prepared using dry pulverization technology. Subsequently, the specimen of paper plastic was verified with mechanical properties, formability and product safety test to confirm the suitable packaging materials for food packaging. Paper plastics showed slightly lower mechanical properties than currently commercialized PP composites. However, paper plastics are valuable materials as environmentally friendly carbon-reducing material because of high biocarbon content, light weight features and applicability of existing manufacturing machines or system.

Fundamental and specific properties of the tennis ball on rubber ball body are surveyed to match the quality of the tennis ball now on applied in the tennis game, 1. Much dose of filler of non-crystalline or flat form applied to rubber compounding than general procedure and over vulcanization is found excellent in the resistant to gas permeability. 2. Flat curing improved characteristics of the ball on the homogenous rebounds when applied on the specified concrete surface. 3. Satisfactory adhesive power is found with Desmodur R and standard rubber recipe in case of applying on the under-vulcanizate of half sphere. 4. The stable gas-generating compounds of sodiun nitrate, ammonium chloride, water and sodium carbonate, anhydorus help controlling of optimum internal over-pressure in the tall.

High surface area and high pore volume activated carbon was prepared by KOH activation of rice hull. The electrodes were fabricated by compounding the commercial and rice hull activated carbons with PVdF and PVdF-PVP mixed binders without addition of conductivity improver. The electrodes fabricated with rice hull activated carbon and PVdF-PVP mixed binders showed the best performance because the PVP played as a pore-forming agent. The electrode exhibited excellent electrochemical characteristics having 7.9 W.h/kg of energy density, 33.5 F/g of speific capacitance, 0.7 $\Omega$ of ESR and good efficiency of self-discharge compared with that fabricated with commercial activated carbons.

Polymers have good electrical properties as an insulation material. Though they show more and less poor resistance to heat, radiation, and oxygen, the poor properties have been overcame by developing new resin with the saturated molecular structure and compounding resin with resistive fillers. Polymer insulators have many advantages; light weight, good mechanical properties, better contaimination performance, low cost by mass productivity, no destruction in many pieces, good flexibility in design, short manufacturing time. Usage of polymer insulators has increased rapidly with good credit on long term properties in advanced nations and will continue to grow.

It is character of Minimalism that representation as a simple shape extremely & objective acess that start from movement of visual art and part of music that began mainly at New York City in America at the end of 1960 period. Then in processing of development of Modernism Art it can be said that Minimalism reach the top of Modernism with that it carried out such character of formed Purity Doctrine of Modernism Art extremely and realized self-restorational character of Minimalism at the pictures that Minimalism is characterized by objectional clearness conceptual strictness reality and simplicity at the picture and by simplicity singularity uninterality and enviromentality at the sculpture. If we analyze Minimalic character in Interior design dividing into the density of space the principle of compound performance of touch and detail those are moderated and simple space simple and repeated compounding of geometrical line and shape the pure techniques of expression and the simplity of pure srtuctural -beauty in detail.

'Digital' the most important keyword in the 21th century environment affects on our life whole and method, studying, working, playing and communicating. Also, digital make the range of products ambiguous through fusing and compounding products. It is becoming new subject how digital may ambiguous with human's life by this solution. So, basis proposition of study analyzes intelligence style furniture taking a view of making of furniture as long as it is by digital technology do essential intensive training of furniture and there is the purpose to suggest conception pattern of 'Digital Convergence Furniture' the future. In especial, analyze intelligence style furniture by investigating space and new tendency that appear on object according to accommodation formula of digital technology through case study it is present conception 'Digital Convergence Furniture'

The comparative studies were made on Salicylamide, used individually and compounded with antihistaminics as regards. (1) the absorption rate through isolated rat small intestine (in vitro) (2) the absorption rate through rat small intestine (in vivo), and the following effects were found. 1. The Absorption velosity of 2 m Mole gm. of salicylamide in the small intestine were decreased, when the agents compounded with tripelennamine indicating the greatest absorption inhibition in the case of m Mole gm. of tripelennamine. 2. The Absorption velosity of 2m Mole gm. of salicylamide in the small intestine were decreased, when the agents compounded with diphenhydramine indicating the greatest absorption inhibition in the case of 2m Mole gm. of diphenhydramine. 3. The Absorption velosity of 2m Mole gm. of salicylamide in the small intestine were increased, when the agents compounded with chlorpheniramine indicating the greatest absorption augmentation in the case of 0.2m Mole gm. of chlorpheniramine.

In this study, based on Choi, Jong Rim's script (2000), the main characters' stage costume designs were presented with 15 illustrated pieces in terms of compounding the images of Korea and West. I considerered the main characters' social status and personality by each act and scene, as well as the correlation of the stage costume's minor theme, color and material. In expressing the stage costume, this study has chosen the formational method of the comparative design dimensions between costumes in 1650s Joseon and baroque period and used the joinder of flat pattern and draping in various parts of the costumes.

In this paper, the negative Polya-Eggenberger distribution has been introduced by compounding negative binomial distribution with beta distribution of I-kind which generates a number of univariate contagious or compound (or mixture of) distributions as its particular cases. The distribution is unimode, over dispersed and all of its positive and negative integer moments exist. The difference equation of the proposed model shows that it is a member of the Ord's family of distribution. Some of its interesting properties have been explored besides different methods of estimation been discussed. Finally, the parameters of the proposed model have been estimated by using a computer programme in R-software. Application of the proposed model to some data, available in the literature, has been given and its goodness of fit demonstrated.

This paper presented a new scene change detection method of compounding color histogram and $x^2$ histogram. This method overcomes the disadvantages of difference value detection methods and will be taking advantage. Also, this method can detect all from the abrupt scene change detection to gradual scene change detection. The proposed method has been compared with previous method, and our experimental results show the better results than the previous method.
