The needs of strategic approach toward the usage of the Internet in corporate context are increasingly important as digital economy changes the way of doing business. However, companies are not easily taking the opportunity since the strategic use of the Internet is difficult because of the conflicts in distribution, business process, organization structure, etc. The Internet strategy applicable to companies in a generic context is proposed by identifying the CSFs (Critical Sucess Factors) in exploiting the potential of the internet. CSFs are derived by the previous study and case analysis, from which two most important factors are chosen based on a survey. In the survey, the ranking of the significance of the 8 CFSs from the 25 cases is questioned to the internet experts. Then a $2{\times}$2$ matrix is designed to find the optimal area for a company to be successful in the Internet usage. The strategy suggested here appears to be the shifting strategy in order to be in the optimal area in using the Internet strategically.

Dynamic response and economic of a laminated porous concrete beam reinforced by nanoparticles subjected to harmonic transverse dynamic load is investigated considering structural damping. The effective nanocomposite properties are evaluated on the basis of Mori-Tanaka model. The concrete beam is modeled by the sinusoidal shear deformation theory (SSDT). Utilizing nonlinear strains-deflection, energy relations and Hamilton's principal, the governing final equations of the concrete laminated beam are calculated. Utilizing differential quadrature method (DQM) as well as Newmark method, the dynamic displacement of the concrete laminated beam is discussed. The influences of porosity parameter, nanoparticles volume percent, agglomeration of nanoparticles, boundary condition, geometrical parameters of the concrete beam and harmonic transverse dynamic load are studied on the dynamic displacement of the laminated structure. Results indicated that enhancing the nanoparticles volume percent leads to decrease in the dynamic displacement about 63%. In addition, with considering porosity of the concrete, the dynamic displacement enhances about 2.8 time.
