A numerical procedure is introduced to calculate local ventilation effectiveness using the definitions of local decay rate and local mean age. A low Reynolds number $k-{\varepsilon}$ model is implemented to calculate steady state turbulent velocity distributions, and a step-down method is used to calculate transient concentration distributions. Simulations are carried out for several different values of air change rates and several different diffuser angles in a two-dimensional model of a half scale office room. The results show that the local ventilation effectiveness within a room could vary significantly from one location to another. The nominal air change rate based on the assumption of complete mixing of room air does not provide the local ventilation effectiveness information. It is numerically proved that the local mean age distribution obtained from the transient calculation is equivalent to the steady state concentration distribution with homogeneously distributed contaminant sources.

This study intended to test the structure of the latent factor of an effectiveness scale and the stability of invariance across groups of students' classifications (gender and levels of education). In the large, non-clinical sample (850), students completed the effectiveness scale. The (CFA) confirmatory factor analysis was used to investigate the factor-structure of the measure, and multiple-group confirmatory factor analysis (MGCFA) model was used to test the stability of invariance across groups of students' classifications. The findings of the CFA indicated support for the original four-factor model. Additional analyses of the MGCFA method support the measurement (configural, metric and strong) invariant and practical invariant components of this model. There was an invariant across gender. There was partially invariant across groups of levels of education. The scale exists in groups of levels of education assess the same concepts of, excluding Items 15 and 10. Given that this study is the first investigation for the structure of the effectiveness scale.

The conventional model of the heat engine involves the inconsistency with the real engine that the power becomes to be zero at the maximum effectiveness condition. In order to improve this defect, a new model of the heat engine is proposed, in which the heat loss from the heat source is taken into account. In accordance with this model, both the power and effectiveness have their respective extremum with respect to operating conditions, and the effectiveness always becomes to be zero when the power is zero.

Research on how to develop information systems efficiently and effectively since early 1960s has resulted in many techniques, methods and methodologies. Only a few of them, however, have been successfully practiced in the field. Model-Driven Development(MDD) is an innovative approach emphasizing the central role of model for development activities, attracting many practitioners' attention as well as researchers'. As MDD matures, many researchers have been trying to establish the evidence of its effectiveness. But many of them only suggest lessons learned or report limited evidence of effectiveness based on isolated case studies. This paper reports the state of the art of Model-Driven Engineering(MDE) and its major issues. We reviewed a number of papers and collected the conceptual definitions of MDE effectiveness from the technological and organizational perspectives. A case study in which MDD technology was adopted has been performed in order to measure the effectiveness of MDD quantitatively and qualitatively. This paper also analyzes and summarizes key considerations and lessons learned for IT organizations to adopt MDE successfully from the case study.

In today's highly competitive environment, the importance of technology protection cannot be overemphasized. To evaluate technology protection competency of Small and Medium-sized Enterprises(SMEs), Government has conducted surveys every year but its effectiveness is still in question. To enhance the effectiveness of technology protection for SMEs, a customized evaluation model of technology protection competency has been suggested in this study. Surveys are conducted to measure the relative importance of evaluation areas that can be influenced by the size and type of business. The analysis shows that there exists significant differences between evaluation areas. This study suggests that the effectiveness of technology protection can be enhanced by utilizing a customized evaluation model depending on the size and type of business. Also, the proposed model can be used for SMEs to identify and enhance their weakness in technology protection. Overall, it is expected that the proposed model can be effectively used to protect valuable technologies in various SMEs.
