3) The superiority of Ti plate as the substrate of dye-sensitized solar cells
This figure is light irradiation in DSSC's based on (a) metal substrate(Ti, stainless steel) and (b) FTO substrate. In this paper, nano crystalline TiO2 coated on FTO, Ti and stainless steel substrated was applied as a photoelectrode of DSSCs.
In conclusion, the sheet resistance of metal substrate seems to be const

Consider Surface area of 3cm*3cm
The surface area of a horizontal wire line is
The surface area of a vertical wire line is
Horizon wire line and vertical wire line has each 73 and 400 in 3cm * 3cm. So the entire surface of plate is
The surface of plane stainless steel of 3cm * 3cm is 9cm2, so the surface of wire mesh is 710% of the surface of plane stainless steel.

III. Company Analysis
1. Organizational Structure
By and large, the steelmaker’s organization structure was highly centralized like any other Korean company in the past. With the appointment of CEO Ryu Sang-Bu in the mid-90s, however, POSCO gradually sought greater decentralization and diversification of a firm that was desperate for flexibility and autonomy. It was not until early 2010 thou

Benefits from integration
Increase flexibility and control on prices
Manufacture steels specifically tailored for its own designs
Provide stable supply and faster development time for products
Increase ability to resolve quality issues quickly

일회용 포장용기 사용 현황
중량물의 경우 Box 당 약 15kg 정도 적입 중.
Box가 상부 무게를 지지하지 못하여 중포장 Case와 혼용 중.
화재 위험이 있는 경우 별도의 공정 용기에 이재하여 라인 투입 중.
Returnable 용기 특징
박스가 중량을 지지하기 때문에 중포장 Case 필요 없음.
