The increase of wet web solid content after wet press and dry compressive strength were observed in lab study by judicious application of wood flour and starch for the old corrugated container (OCC). Pearl starch was better than cationic starch in strength development, but cationic starch was better for drainage. Application of vacuum on the mixed solution of wood flour and starch helped strength development further without loss of other properties. The effect of wood flour addition on wet web solid content improved as the wet pressing pressure increased. The use of wood flour and starch mixture improved wet web solid contents further.

30 kVA rotating-field type Super-Conducting Generator is built and tested with intensive FE(Finite Element) analysis. The generator is driven by VVVF inverter-fed induction motor. Open Circuit Characteristic(OCC) and Short Circuit Characteristic(SCC) are presented in this paper. Also, the test result under the light load(up to 3.6 kW) are given. From the design stage, 2-D FE analysis coupled with the external circuit has been performed. The external circuit includes the end winding resistance and reactance as well as two dampers. When compared with the test data, the FE analysis results show a very good agreement.

The effects of polyelectrolytes and enzyme, alone and in combination, were investigated in OCC recycling system. Four types of the polyelectrolytes based on acrylamide, cationic and anionic monomers were applied to the enzyme-treated KOCC stock to improve the strength and drainage properties of testliner. The polyelectrolytes used in this work were designed in terms of molecular weight and charge density. The water conditions used for recycling were also varied. The results showed that the hydrolytic action of enzyme gave reduced surface area and amorphous region of fiber, and as a result, the cationic polymer was lost apparently its flocculating power due to the reduced bonding site of fiber surface. When the hardness and conductivity of water had been controlled to the conditins of OCC paper mill, the application of amphoteric polyelectrolyte to the enzyme-treated recycled stock was the most effective with respect to the strength and drainage properties of testliner.

A great difference in drainage time was observed from the recycled stocks between corrugated container board and its component papers, liner and medium paper. It could be assumed that the different drainage property should be caused from a starch adhesive present in the corrugated board. Thus, three types of starch such as dried Stein-Hall adhesive, cooked starch solution, and its dried film were added to linerboard stock in order to investigate the mechanism of drainage reduction. The water-swollen starch particles derived from Stein-Hall adhesive were drastically deteriorated the drainage time, even though the amount of starch is very small (2% or below). The drainage time of OCC was improved by 25% when amylase was used a new biological treatment. The results from the lab and mill test showed that the starch-degradable enzymatic treatment improves the drainage property as well as the reduction of calcium hardness.

A fiber processing method, which might be an alternative for conventional refining process, was introduced. The method consists of repetitive, gentle, mechanical impacts on fiber, and ensued fiber uncurling process. This method was very effective for OCC and BCTMP for increasing WRVs (water retention value) while keeping fiber lengths from shortening. For OCC and BCTMP, gentle mechanical impacts on fibers using Hobart mixer increased breaking lengths and tear strengths simultaneously at fast drainage level, and straightening fibers using kady mill increased those strength properties further. For SwBKP and HwBKP, only mechanical impacts using the mixer were effective on increasing tensile and tear strength at fast drainage, but not kady mill treatment. The strength increases of BCTMP by this alternative fiber processing method were exceptionally high. An extensive engineering development should be followed to actualize this fiber processing mechanism in an energy-effect way.

The blended enzymes were applied for OCC recycling system to use the selective activities of various enzymes. Cellulase and hemicellulase were very effective in terms of the strength of recycled paper The effect of the addition of amylase on the drainage improvement indicates that the starch, which was used as an adhesive of corrugated container, deteriorates the drainage property in OCC recycling system. From the result of Scheffe's analysis, the combination of cellulase and amylase (50/50, w/w) were the most effective in improving the drainage properties with increased strength.

We have generated a novel baculovirus genome which can be maintained in Escherichia coli that facilitates the rapid and efficient generation of recombinant baculovirus expression vectors. To make $Occ^{+}$ recombinant expression vectors, polyhedrin gene under the control of p10 promoter was inserted to bAcGOZA and this genome was designated bApGOZA. As in bAcGOZA, bApGOZA lacks a portion of the essential ORF1629 gene, but includes a mini-F replicon and selectable kanamycin-resistance marker, This occasion-producing activity of bApGOZA can be used very conveniently for its oral infectivity to insect larvae in mass production of foreign protein and insecticides.

The whole volatile flavor concentrate obtained from Jindalrae flower was separated into hydrocarbon and oxygen-containing compound(OCC) fractions, and the OCC-fraction was further separated by column chromatography into nine sub-fractions, respectively. These fractions were analyzed by gas chromatography and combined gas chromatography/mass spectroscopy. One hundred and sixty-two components, including 61 hydrocarbons, 18 aldehydes, 18 esters, 41 alcohols, 3 ketones, 4 oxides, 8 acids, 6 phenols and 3 miscellaneous components, were identified.

개인의 감성에 잘 부합하는 컨텐츠를 제공하기 위해선 개인의 취향과 컨텐츠를 이용할 때 어떤 감정을 가지고 있는지 알아야 한다. 개인의 취향을 알고 있다면 취향에 부합하는 컨텐츠를 재분류 할 수 있고 개인이 컨텐츠를 이용하려할 때의 감정 상태를 알 수 있다면 분류된 컨텐츠 중에서 감성에 부합하는 컨텐츠를 빠르게 제공할 수 있다. 본 논문은 개인의 취향을 인식하고 감정상태를 추측하여 연동된 플랫폼에 감정상태에 따른 결과를 출력하는 감성엔진을 제안 한다. 성격이 비슷한 사람은 비슷한 취향을 가지는 성향이 있으므로 취향인식을 위해 개인의 성격을 구별했고, 구별도구로 MBTI를 이용했다. 감정 추측을 위해 주변에서 일어나는 환경의 정보를 OCC 모델을 기반으로 분석하여 감정자극의 종류와 크기를 산출했다. 감정자극들을 감정그래프를 이용해 감정의 생성, 유지, 소멸을 관리하고 감정감정 상태에 맞는 결과를 출력했다.
