플라즈마 용사(spraying) 공정을 이용하여 형성한 단열코팅층에 대한 연구를 수행하였다. 이 단열코팅은 공구강(KS 규격 : STD61) 기판위에 8wt%의 이트리아로 부분안정화된 지르코니아 분말을 사용하여 코팅하였으며, 본드코팅층은 니켈합금 분말을 사용하였다. 실험계획법으로서 플라즈마 용사 공정의 주된 영향을 미치는 인자를 선정하였고, 이에 대한 분석은 통계분석법 중 하나인 분산분석을 행하였다. 코팅층의 미세조직 및 기공도는 전자주사현미경과 영상분석기등을 사용하여 관찰하였고, 코팅의 품질은 단열효과, 열충격시험에 대한 저항성 등으로 평가하였다. 또한 기판과의 접착력 시험을 행하였다. 고도의 단열코팅층을 형성하기 위한 최적의 플라즈마 용사 공정변수는 실험계획법과 통계적 분석방법을 통하여 찾아낼 수 있었다. The formation of thermal barrier coating(TBC) layer using plasma spraying process was studied. Zirconia(partially stablized with 8wt% Yttria) coating was prepared for the TBC by plasma spraying on tool steel (KS : STD61) substrates. NiCrAlY powder was sprayed as a bond coating layer. Design of experiments was used to derive the main parameters of processing and determined the process parameters according to the analysis of variance. The microstructure and porosity of the coating were characterized using SEM, Image analysis etc. Coating qualities are discussed with respect to thermal barrier effects and thermal cycling test. And adhesive strength test was carried out. Optimum coating parameters which were derived from the statistical analysis could be found for high quality TBC.

The benefits reaped from engaging in a tax-avoidance activity have been subject to abuse by resident enterprices through retainig gains in the foreign subsidiariese usually located in the tax havens. In case of korea, it is of recent issue to cope with the International Tax Evasion through Tax Havens. Since It has passed only 10 years since korea introduced CFC legislations, systematic taxation skills and precedent cases have not yet accumulated. also United states which adopted CFC rule first is the second larestcountry of foreign direct investment on korea's side and many korea-based multinational enterprises are expected to be subject to the US CFC legislation. and for japan, CFC rules are much similar to that of korea's and several cases which can also arrise in korea were judged by the jurisprudence. But previous studies have been only focuced on the study of CFC Rules conducted by comparative analysis of major foreign country's CFC legislations. So in this study we scrutinized US and japan's jurisprudences and taxation systems as well as CFC legislations including the Inversion trasactions which try to evade CFC applications

This paper estimates the income report ratio of self-employed by comparing Input-Output Table and tax return data. We decompose the income report ratio into sales report ratio and net-of-cost share report ratio. Our results show that low income report ratio is derived from poor sales report ratio, approximately 51.2% at 2000. Net-of-cost share report ratio is relatively close to the real cost structure due to government's guidelines and lack of taxpayer's interest. This implies that we need to build more clear transaction system for higher sales report ratio.
