This paper will introduce the development case study about virtual-reality-based operation training system for steel making process. Steel making process consist iron making process to create liquid steel, pig iron, by reduction process, steel making process to make molten steel by refining, continuous casting process to make slab, and rolling process to make final product like coil, plate. This steel making process deals with liquid and solid products, so facilities of steel making process are very various and complicated. In addition, according to various customer requirements, the recycle of facilities and recipes changing have been fast. So the training for skilled operators is very important point. In this paper, we develop steel making training system based virtual reality for training skilled operator. This system consists of virtual machine, virtual HMI, and virtual control panel. And for fitting the characteristics of each process and increasing the education effectiveness, we develop dynamic methods like the method of dynamic education system configuration, initial facilities setup operation education system, and etc.

An effective and convenient regioselective reduction of 5-benzylidene 2,4-thiazolidinedione derivatives to the corresponding 5-benzyl 2,4-thiazolidinedione derivatives has been accomplished using 3,5-dicarboethoxy-2,6-dimethyl-1,4-dihydropyridine (Hantzsch dihydropyridine ester: HEH) with silica gel as an acid catalyst in a good yield.

The purpose of this paper was to study interior design research trend through categorizing the research in interior design process and investigating the research method used at each stage of the process. The ultimate aim was to evaluate the relationship of design process and interior design research and to indicate the guide line of future research. As results of the study, interior design research did not reflect recently increasing renovation and remodeling trend since evaluation research was less performed than data collection, program and design development research. Only educational/research space showed higher rate in evaluation research. In recent years, interior design research is interested in objective design problem solving since programming research Increased, and in user-participation planning since questionnaire and interview research Increased as data collection method. For the future research, it is expected researchers to show creative thinking process on the stage of design development and to develop various research method on the stage of evaluation.

Atorvastatin calcium salt (1) was obtained through the preparation of lactone compound (8) from 2-((4R,6R)-6-(2-(2-(4-fluorophenyl)-5-isopropyl-3-phenyl-4-(phenylcarbamoyl)-1H-pyrrol-1-yl)-ethyl)-2-phenyl-1,3,2-dioxaborinan-4-yl)acetic acid tert-butyl ester (9) by hydrolysis in basic condition. Efficient hydrolysis of boronate compound 9 aimed at the viable synthesis for commercial production and purification of Atorvastatin calcium is reported. Detail studies of evaluation procedure are also reported.
