The purpose of this study is to clarify the reality of labor and capital productivity in the construction industry through an industry-level approach and to analyze the relationship between labor and capital productivity using a Cobb-Douglas production function. According to the research results, the construction industry has shown a very high capital productivity, while labor productivity has kept up a low level during the 1980s and 1990s. The reason was because of the lack of skillful construction workers and the decrease of capital. Meanwhile, the construction productivity has greatly increased since 2000 when there was no change in wages. This was because of a large inflow of low-wage foreign workers while the amount of value added has dramatically increased due to the liberalized sale price of apartment buildings. According to the analysis by the Cobb-Douglas production function, the elasticity coefficient of V/L to K/L in the construction industry had decreased from 1.1663 in the 1^st period(1971-1988) to 0.4465 in the 2^nd period(1989-1997), and to 0.1664 in the 3^rd period(1998-2003). Such a result means that the allocation of labor has gradually increased while the allocation of capital has decreased. Moreover there was a big increase in allocation of labor after 1998 due to the excessive deterioration of capital. In conclusion, in order to raise the construction productivity and to avoid labor-intensive production methods, investment for capital should be more increased. In particular, new machinery and equipment that can actually substitute human labor in construction sites should be more developed and applied to construction sites.

Over the last two decades, interest increased with regard to how some research universities made direct impacts on surrounding regional economic activities and growth. Although the role of basic research for most research universities has remained strong, pressure has intensified to broaden its missions to include helping local and regional economic development efforts. Consequently, many research universities have evolved their basic scientific research mission from the production of scientific knowledge to the sharing and exchange of knowledge with local industries by actively engaging in local economic development (Uyarra 2010). Previous examination has shown that most research universities contribute to local and regional economic development by various functions they provide. They are as follows: Creation of Knowledge, Human-capital creation, Transfer of existing know-how, Technological innovation, Capital investment, Regional leadership, Knowledge infrastructure production and Influence in regional milieu (Drucker and Goldstein 2007). This paper will review the existing literature on the role of universities and its impacts on local regional economic growth and development. In addition, this paper will show how two major research universities (The University of Arizona and Arizona State University) have contributed to the growth of Arizona during last two decades. It is believed that the existence of these two research universities have been instrumental in making industries more diverse and highly attractive, particularly in the Phoenix Metropolitan Area.

Graphite has excellent mechanical and physical properties. It is known to advanced materials and is used to materials for molds, thermal treatment of furnace, sinter of diamond and cemented carbide tool etc. SiC materials are coated on the surface and holes of graphite to protect particles emitted from porous graphite with 5%~20% porosity and make graphite hard surface. SiC materials have high durability and thermal stability. Thermal CVD method is widely used to manufacture SiC thin films but high cost of machine investment and production are required. SiC thin films manufactured by Si reaction liquid and vapore with carbon are effective because of low cost of machine and production. SiC thin films made by vapor silicon infiltration into porous graphite can be obtained for shorter time than liquid silicon. Si materials are evaporated to the graphite surface in about $10^{-2}$ torr and high temperature. Si materials are melted in $1410^{\circ}C$. Si vapor is infiltrated into the surface hole of porous graphite and $Si_xC_y$ compound is made. $Si_x$ component is proportional to the Si vapor concentration. Si diffusion coefficient is estimated from quadratic equation obtained by Fick's second law. The steady stae is assumed. Si concentration variation for the depth from graphite surface is fitted to quadratic equation. Diffusion coefficient of Si vapor is estimated at about $10^{-8}cm^2s^{-1}$.
