In Response Surface Methodology (RSM), rotatability is a natural and highly desirable property. For second order general correlated regression model, the concept of robust rotatability was introduced by Das (1997). In this paper a new measure of robust rotatability for second order response surface designs with correlated errors is developed and illustrated with an example. A comparison is made between the newly developed measure with the previously suggested measure by Das (1999).

Topological insulator (TI) has non-trivial metallic surface states and has provoked many studies of property of this metarial. One of TI, $Bi_2Se_3$ is the promising metarial due to application of quantum devices. We investigate the effect of Ag adatom in the $Bi_2Se_3$ (111) surface. The silver atom prefers to locate within the vdW gap between the QLs rather than on the top surface. The effect of Ag adsorption is the rise of the Fermi level implying that the adsorbed Ag atoms behave like electron donors.

Although the surface of aluminum alloy has good corrosion resistance property, the surface of the aluminum rolling stock should be painted for good appearance and protection of the body. For better painting of the aluminum carbody, the surface must also be well pretreated. In this paper, painting process of the aluminum rolling stock is described and the test results of the painted surface is presented. As accumulated data concerning to the painting technology for the aluminum rolling stocks are absent in our country, the presented test results will be helpful for mass production of aluminum rolling stocks in the near future.

이번 실험에서는 건식 도금방법을 이용한 알루미늄 도금강판의 조성 및 두께에 따른 내식성 평가를 염수분무 실험을 통해 측정하였다. 실험 결과 도금 조성 내 Silicon의 조성이 증가할수록, 일반적인 건식도금 방법보다 조직 성장 시 도금 층에 각을 주어 도금하는 것이 내식성을 향상시키는 것으로 관찰되었다.
