Effect of shapes (noodle, grain and brick types) and strains (Aspergillus oryzae and Aspergillus sojae) of Meju (microorganism inoculated soybean substrate for fermentation) on the quality of soy sauce was investigated. Generally, the highest protease activity was found in the noodle type-Meju inoculated Asp. sojae during Meju preparation and soy sauce brewing, however, the lowest value was noted in brick type. Meju inoculated Asp. oryzae. Similar tendency was found on the contents of total solid, total nitrogen, amino-nitrogen, nitrogen digestion yield and amino-nitrogen ratio during soy sauce brewing. No effect was shown on the reducing sugar content, alcohol formation, pH, buffer action and salt content according to different Meju types during soy sauce brewing. Organoleptic tests on the color, taste and flavor of soy sauce after 3 months brewing with various Meju scored in the order of noodle type-Asp. sojae soy sauce (best quality), noodle type-Asp, orzae soy sauce, brick type-Asp. sojae soy sauce and brick type-Asp. oryzae-soy sauce (worst quality).

This study is to diagnose causes of damage and defects on external walls of brick structures, focused on "Naju Noahn" Catholic Church of Modern Architectural Properties. The causes of crack and deflection are overloading, shortage strength of arch. Among those, main cause is cauesd by shortage strength of arch because center of arch is dislocated and skew back of arch is small angle. The causes of damage and elimination are weathering, plants of friction, freezing and thawing, durability decrement of material and attach defection. This defects and damage is caused by high-moisture that occurs in soil. The causes of discoloration are change of soil moisture and flimsy brickwork. These defects and damage are mainly occurred in coping of cornice, weathering of window sill.
