After fifteenth century artists sought for a method on representation of nature through perspectiva artificialis. Perspectiva artificialis is become a tool for establishment of their theory and value. This study aim to study Orientation and mean of Anamorphosis in Architectural Perspective and transitional procedure of perspective in appealing the will of Architects. Initially, the concern of perspective is begun with optics in the Middle Ages. In Renaissance Ages perspective are presented a scientific and real world to a transformation of non-scientific world with visual cone, vanish oint and anamorphosis. In artists anamorphosis specially is a effective means to emphasize a affect of mannerism. Accordingly, perspective is discoursed to approached between art and technique. After renaissance perspective is become the driving force of the representation in spirit of scientific investigation ; while anamorphosis such a manneristic present in art is motived to prevent from obtaining its universe and implicity through their methodology.

The older granitic rocks of the study area are composed of mainly orthogneiss and foliated granite. These rocks shows mostly mortar or fiaser structure by strong mylonitization and thermal metamorphism during several orogenies. $^{40}Ar-^{39}Ar$ incremental·release ages of these rocks have been determined for 6 hornblende. 7 muscovite and 4 biotite concentrates separated from rocks collected across the Ryeongnam massif. Most $^{40}Ar-^{39}Ar$ age are discordant with Rb-Sr whole rock age of the same area. These ages range from 1998 to 172Ma. This discordant age is interpreted to indicate that samples were in contact with Daebo granite body that was characterized by large and variable $^{40}Ar-^{39}Ar$ ratios. Such ratios most likely resulted from widespread diffusion of the argon liberated from older granitic rocks during several metamorphic overprint. The general trend of the chemical composition of these rocks suggest that most of them are some series of differentiated products by fractional crystallization.

Cloride attack of concrete is one of the important causes of corrosion of reinforcing steel in concrete with carbonation and frost damage. In this paper, the effect of fly-ash on the cloride attack were investigated by varying water binder ratio and fly-ash contents according to the chloride ion penetrationa test. (ASTM C 1202-94) The principal conclusions from this research were as follows: 1) The compressive strength of concrete at large ages, depends more on $C_2$S contents of base cement than fly-ash contents. 2) On the other hand, the chloride ion penetration of concrete at large ages, principally depends on fly-ash contents and the influence of type of base cement is insignificant.
