A manufacturing company should produce its products and make a profit to continue its management. With the adoption of a multi-category small-volume production system, manufacturers that produce concrete pump-cine products are carrying out improvement activities to increase their market share amid the business-to-customer business environment. However, the slump in the construction investment environment has led to a decline in sales of concrete pump trucks. The purpose of holding inventory is to prevent loss of sales opportunities with the rate of change in the sales plan, and reducing the rate of change in the product can reduce unnecessary inventory and, in order to realize this, the goal of reducing inventory can be achieved by reviewing the parts that can be designed for common use. Therefore, to reduce the inventory of concrete pump trucks, semi-finished publicization design is necessary. According to the analysis, the frame assembly process of the 32M model is common. Production capacity can be secured without loss of sales opportunity.

Koji (Aspergillus oryzae) is used to ferment crude cereals of wheat to make a traditional alcoholic drink called Makkolli and industrial materials. It’s quality varies depending on the wheat quality. Four domestic wheat varieties (Kosomil, Jokyungmil, Geumgangmil, Baegjungmil) were characterized. They were found similar in pH (6.02 to 6.08) and total acid (0.105 to 0.120%) contents. However, amino acid content of Gemgangmil was the highest (4.46%) and that of Baegjungmil was the lowest (3.72%). The total bacillus number was highest in Kosomil (333×103CFU/ml) and lowest in Gemgangmil (60×103CFU/ml). On the other hand, the fungus number was 47×105CFU/ml in Gemgangmil and the other varieties had similar quantity. The content of Alpha-amlyase was the highest (500.01unit/g) in Kosomil followed by Jokyungmil and Gemgangmil, and the lowest was in Baegjungmil (353.32unit/g). The content of Glucoamlyase was the highest in Geumgangmil (5105.0unit/g) followed by Jokyungmil and Kosomil, and the lowest was in Baegjungmil (3880.0unit/g). Acid protease was the highest in Kosomil (3515.15unit/g) followed by Geumgangmil and Baegjungmil, and the lowest in Jokyungmil (1280.5unit/g). From the result, Koji made from Kosomil was found to be of superior quality.
