As environmental issues are attracting more attentions world widely, Steel House is emerging as a way forward. Since Steel House is a relatively new technology in Korea, its design and construction needs improvement in terms of interfaces. The objective of this study is to consider the application of CII Constructability Concepts to Steel House. The paper discussed initial findings and proposed the use of multi-media technology as a next research agenda.
Luminescence Property of ZnS:Mn,Mg Phosphor with Excitation of Plasma Blue Light Source
류시홍,김완규,이성의 한국전기전자재료학회 2013 Transactions on Electrical and Electronic Material Vol.14 No.1
In this paper, we investigated the effect of luminescence properties of various concentrations of magnesium-doped ZnS:Mn phosphor excited by plasma luminescence device. The PL intensity was evaluated in the range of 300~500nm excitation wavelengths. We found the highest PL intensity of the phosphors excited by 365 nm and 450 nm was observed at Mg concentrations of 1.4 wt% and 0.8 wt%, respectively. In addition, an emission peak was distinguished at 580 nm wavelength. With increasing Mg dopant level, enhanced PL intensity was observed, which is possibly applicable to color converting materials by blue emission for white light sources. Finally, we evaluated the luminance properties of color converting ZnS:Mn,Mg phosphors with plasma blue light source. the white luminance of plasma light source with CIE(0.36,0.26) was established by color converting phosphors of ZnS:Mn with 0.8 wt% Mg.

Value Engineering is introduced and performed as an alternative to increase the productivity and effectiveness of the construction projects, which can eliminate budget overrun and inefficiency in the process of construction. But, some problems are anticipated when the VE study is performed. The purpose of this study is to improve the major problems which are $quot;the rejection for the VEJP by the original designer$quot; and $quot;the lack of application of construction knowledge by professional engineers$quot; during the VE Study. The consequential results in this study are as follows ; their participation as a full-time member is necessary and the partnering and the constructability concepts are useful tools. For their participation, this study suggests $quot;Joint Value Engineering Model(JoVE)$quot; which is using the partnering and the constructability concepts in VE Study.
