    摘要： The present invention relates to a transition metal half metallocene catalyst with a noble structure for preparing syndiotatic styrene polymer having high activity, superior stereoregularity, high melting point and broad molecular weight distribution and a process for preparing styrene polymer using the same. The present invention provides a half metallocene catalyst having a single nucleus structure, in which a transition metal in Groups 3 to 10 on the periodic table is connected to a cycloalkanedienyl group or its derivative forming 5-coordinate bond on a side thereof and to any one of triethanolamine, N-alkyldiethanolamine and N-dialkylethanolamine group, all of which have a plurality of binding sites and high steric hinderance, on the other side thereof. The noble metallocene catalyst according to the present invention is useful for preparing highly syndiotatic vinyl aromatic polymer with broad molecular weight distribution and high activity.

    摘要： A computer system, a control method thereof and a recording medium storing a computer program thereof are provided to recover a program efficiently and be resistant to viruses, worms, and user error. The control method of computer system receives a user's request for a recovery of a program which is installed in a first storage unit. A file system of a second storage unit is determined which stores therein a recovery program corresponding to the program for which the recovery is requested. The recovery program is read from the second storage unit with reference to the determined file system, and the program in the first storage unit is recovered by using the read recovery program.
