As environmental damage increase by a highly developed material civilization of today, many companies take a growing immensely interest in the influence of environment for beginning a new paradigm year by year. The previous assessments dose not run the gamut of industry but is confined within a certain facility or an area. Industrial processes and operations can not be accomplished independently but are connected with each others through suppliers and customer, and these ideas are fundamental notions of Life Cycle Assessment(LCA). This paper will introduce Life Cycle Assessment(LCA) n environment which is rising, and would like to build environmental management system using approach of Quality Function Development(QFD) and Safety Function Development(SFD) belonging to the assessment method.

Acrylic resins (HSCs : EA/EMA/2-HEMA/CLA) which contain 70% solid content were synthesized by the copolymerization of monomers (2-hydroxyethyl methacrylate, ethyl acrylate, and ethyl methacrylate) and functional monomer (caprolactone acrylate : CLA) which improves the crosslinking density and physical properties of films. The physical properties of the prepared acrylic resins (HSCs) containing CLA, are as follows : viscosity 245~515 cps ; Mn 2670~2840 ; and conversions, 83~91%, respectively. From the correlation of Tg values, viscosities, and Mn of the HSCs, it was found that viscosity and Mn increased with Tg value.

An emulsion of octadecamidoethylaminoethyl dodecate (which provides softness) and an emulsion silicone oil KF-96 (which provides lubricity) were separately synthesized. Then PP finishing softeners (SSA-7) was prepared by blending of the synthesized emulsions with beef tallow hardened oil (a softness improving agent). PP finishing treatment was carried out with the prepared SSA-7 and PP finishing resin by a one bath method, and several physical properties were tested. As a result, crease recovery, tear strength, softness, lubricity, and bending resistance were all good, indicating that the prepared SSA-7 is a good PP finishing softener.

This study for preparation of aluminum nitride (AlN) with high purity was carried out by self-propagating high-temperature synthesis method in two different systems, Al-N and Al-N-AlN, with the change of nitrogen gas pressure and dilution factor. On the occasion of Al-N system, unreacted aluminum was detected in the product in spite of high nitrogen pressure, 10 MPa, This may be caused by obstructing nitrogen gas flow to inner part of molten and agglomerate of aluminum, formed in pre-heating zone. In Al-N-AlN system, AlN with a purity of 95% or ever can be prepared in the condition of f 0.5, PN2 1 MPa, and the purity can be elevated to 98% over in the condition of f = 0.7 and PN2 = 10 MPa

Low foaming scouring agents (LSSA) were prepared by blending of amine salt of dodecylbenzene sulfone, poly (PO-b-EO) glycol, Newpol PP-2000, MJU-100, ethylene glycol and organic solvent. As the results of several tests, LSSA-2 showed good scouring effect, penetrating ability and emulsifiability, and showed not much water pollution. The foaming power of LSSA-2 measured by Ross & Miles method was 11mm foam height immediately after foaming. And the foaming power of LSSA-2 measured by Ross & Clark method were less than 310mm foam height at 30℃, 17mm at 80℃. As a result, LSSA-2 was proved as a good foaming scouring agent.

연구의 궁극적 목적을 두었다. 일반 사육환경에서 나타날 수 있는 발육온도(20, 25, 3)와 최종령 초기 유충 체중 변이(412.6-1,616.0 mg)는 누에의 용화 결정에 영향을 주지 많았다 한편 유약호르몬(juvenile hormone：計I)동력제인 피리프록시팬(pyriproxyfen)은 10-s M의 낮은 농도에서도 난포세포 개방화를 유도하여, 이 약제가 누에에서도 동력제라는 것을 확인하였다. 피리프록시펜은 약제 농도 및 처리 시기별로 특이하게 누에 미화용 유발 효과를 보였다. 피리프록시펜은 JH 에스테라제(JH esterase： JHE)를 직접적으로 억제하지 못하고, 오히려 활성을 증가시키는 것으로 나타났으며, JH 결합단백질(JH binding protein：JHBP)의 유전자 발현을 억제하는 것으로 나타났다. 즉, 피리프록시펜은 체내에 JH 동력제로 작용하면서 JHE 유전자 활성을 제고시켰지만, JHE활성 증가에 따른 체내 JH함량이 줄어듬에 따라 JHBP의 유전자 활성을 억제하는 것으로 해석된다. 양잠농가 주변으로 살포 가능성이 있는 농약을 대상으로 난포세포 개방화 분석을 실시 한 결과, 제초제 3종(simazine, molinate, alachlor)이 JH 동력제 효과를 가지고 있는 것으로 나타났다. 누에 미화용 원인체 규명을 위해서 이들에 대한 직접 노출 시험이 요구된다.

Ni-diamond composite powders with nickel layer of round-top type on the surface of synthetic diamond (140/170 mesh) were prepared by the electroless plating method (EN) with semi-batch reactor. The effects of nickel concentration, feeding rates of reductant, temperature, reaction time and stirring speeds on the weight percentage and morphology of deposited Ni, mean particle size and specific surface area of the composite powders were investigated by Atomic Adsortion Spectrometer, SEM-EDX, PSA and BET. It was found that nucleated Ni-P islands, acted as catalytic sites for further deposition and grown into these relatively thick layers with nodule-type on the surface of diamond by a lateral growth mechanism. The weight percentage of Ni in the composite powder increased with reaction time, feeding rate of reductant and temperature, but decreased with stirring speed. The weight percentage of Ni in Ni-diamond composite powder was 55% at 150 min., 200 rpm and 7 .
