본 연구에서는 국내외 저탄소 녹색성장을 위한 대안으로서 수소에너지와 그 이용 기술에 대한 관심이 높아지는 추세에 발맞춰 무탄소 연료인 수소를 LNG 의 주성분인 메탄, 메탄-프로판, 메탄-프로판-에탄 동축류 확산화염 내에 첨가하여 화염형상 및 연소생성물에 미치는 영향을 확인하였다. 상온상압 조건의 확산화염에 수소를 단계적으로 첨가하여 실제 생성되는 연소생성물의 변화 추이를 가스 분석기를 이용하여 실험적으로 관찰하였고 확산화염의 형상은 디지털카메라를 이용하여 단계적으로 관찰 하였다. 실험결과에서 확산화염에 수소를 첨가함에 따라 질소산화물의 생성량이 선형에 가깝게 증가하는 경향을 보였다. 이것은 수소의 상대적으로 높은 단열화염온도와 빠른 연소속도가 Thermal NOx의 생성을 촉진했기 때문이다. 반면 이산화탄소의 생성량은 감소하는 경향이 나타났는데 수소를 첨가함에 따라 메탄, 메탄-프로판, 메탄-에탄-프로판의 혼합 확산화염에 포함되어있는 전체 탄소비율이 줄어들어 이산화탄소의 생성량이 감소한 것이다. 이는 선박에서 LNG-수소의 혼합 연료사용으로 인해 온실가스인 이산화탄소를 저감할 수 있는 하나의 방안으로 고려될 수 있다는 것을 의미한다. As a carbon-free, green growth alternative, internal and external interest in hydrogen energy and technology is growing. Hydrogen was added to co-axial methane, methane-propane, and methane-propane-ethane diffusion flames, which are the main ingredients of LNG, to evaluate its effect on flame formation and combustion products. The variation in combustion products produced by adding hydrogen gradually to diffusion pyrolysis at room temperature and normal pressure conditions was observed experimentally by using a gas analyzer, and the shape of diffusion pyrolysis was observed step by step using a digital camera. The experimental results showed that the production volume of nitrogen oxides tended to increase and became close to linear as hydrogen was added to the diffusion pyrotechnic. This is because the relatively high temperature of heat insulation and fast combustion speed of hydrogen facilitated the production of thermal NOx. On the other hand, CO2 production tended to decrease as hydrogen was added to reduce the overall carbon ratio contained in the mixed diffusion flame of methane, methane-propane, and methane-ethane-propane. This means that the mixed fuel use of LNG-hydrogen in ships may potentially reduce emissions of CO2, a greenhouse gas.

A high active protease-producing microorganism was isolated from the spider in Korea. The microbe produces large amount of high active protease, and almost protease is secreted to culture broth. The protease, named to Arazyme, has the unique characteristics as follows. The Arazyme has relatively high enzyme activity not only in ambient but also in low temperature, in wide range of pH, and even in high salt condition. The Arazyme is active in the various kinds of enzyme substrates. The Arazyme has also some antimicrobial activity against various kinds of microorganisms, competitive with several known antibiotics. The Arazyme is well using in the related application fields such as livestock animal feed additives, food processing, laundry detergent, leather processing, cosmetics, and neutraceuticals etc. The Power-cell, One-Q are famous commercial products in animal feed additives, B.A.L. and Enzyme Peeling Gel in cosmetics. This is one of the successful cases in the technology transfer from research laboratory to industry. And various promoting systems of Korean government are absolutely helpful for the technology transfer from research laboratory to industry.

Recently, the high power density and efficiency of interior permanent magnet synchronous motor (IPMSM) for electric vehicle traction has been attracting attention. Particularly in order to overcome the cost issues of rare-earth dependent on China, Magfine magnet, which consists of neodymium without Dysprosium (Dy) and has enhanced coercive force, has been developed. However, Magfine magnet is vulnerable to irreversible demagnetization by external magnetic field. And it is essential to prevent this phenomenon. This paper suggests a design using the magnetic flux barriers in order to decrease the irreversible demagnetization of the permanent magnet (PM). Also, by using the 2-D finite element analysis (2-D FEA), it was confirmed that the permanent magnet irreversible demagnetization characteristic of the proposed model is improved. Thus, when advancing research in consideration of the Magfine fabrication process, it is expected that the commercialization of Magfine magnet can be accelerated with a more accurate performance prediction.

We attempt to study the effects on the rice market in Korea under the special treatment(hereafter MMA or delayed tariffication) and ceasing to apply the special treatment(hereafter tariffication). Japan and Taiwan that were in delayed tariffication had changed the policy in the rice market to tariffication. Two countries show quite different economic effects of the tariffication. Japan has been stabilized in the rice market while Taiwan experienced of sharp decrease in the price. Special treatment for rice shall be extend for an additional 10 years until 2014 in Korea, however, Korea has a right to choose alternatives: tariffication or MMA. Under certainty, tariffication and MMA are equivalent in terms of economic welfare in the static model. There is different conclusions, however, under uncertainty for quantity supplied and rice price overseas. The optimum policy with adjustment cost in rice industry is tariffication under slow reduction of tariff rate. In the expectation of DDA negotiations in 2007, the time to change the policy is expected in 2008. We suggest to use agricultural funds for reformation of the agricultural industry, not to use to promote rice production.
