  • Annual energy consumption in detached houses are affected mainly by thermal performance of envelope. In particular the performance of glasses are critical due to global wanning and climatic change. Therefore, this research analyzes annual consumption of cooling and heating energy with various combination of U-value, shading coefficient and building orientation. The simulation results shows that shading coefficient of glazing contributes to the changes of proportion of heating and cooling energy demand and the optimized shading coefficient for minimizing energy consumption varies with buildings orientation.

  • The objective of this research is to optimize the designing parameters of the parallel manipulator with large orientation workspace at the boundary position of the constant orientation workspace (COW). The method uses a simple genetic algorithm(SGA) while considering three different kinematic performance indices: COW and the global conditioning index(GCI) to evaluate the mechanism's dexterity for translational motion of an end-effector, and orientation workspace of two angle of Euler angles to obtain the large rotation angle of an end-effector at the boundary position of COW. Total fifteen cases divided according to the combination of the sphere radius of COW and rotation angle of orientation workspace are studied, and to decide the best model in the total optimized cases, the fuzzy inference system is used for each case's results. An optimized model is selected as a best model, which shows better kinematic performances compared to the basis of the pre-existing model.

  • We proposes a new fingerprint minutia matching algorithm which matches the fingerprint minutiae by using local alignment. In general, fingerprint is deformed by Pressure and orientation when a user presses his fingerprint to the sensor. These nonlinear deformations change the position and the orientation of minutiae which decrease reliability of minutiae. Matching by using global alignment uses one alignment point. But, the problem with this method is that, due to the deformation, matching reliability of a minutia decreases as the distance from the alignment minutia increases. Matching by using local alignment overcomes this problem by considering minutiae which are located in a short distance boundary. Experimental results show that the performance of the proposed algorithm is superior to that of using global alignment.

  • Due to the increasing concerns about the buildings which have affected the global environment, most countries have enacted a regulation for the sustainability of domestic buildings. In 2008, the Korean government started to enact a regulation of apartment and office buildings for energy saving. Many research on the sustainable apartment building focuses on $84m^2$ or larger type in response to market demand; therefore, small size type such as $46m^2$ type needs to be researched. In addition, the research on the orientation and window to wall ratio of the building have been separately studied as a means of energy reduction; therefore, the research on correlation of the orientation and window to wall ratio hasn't been fully explored yet. This paper analyzes the energy demand of the apartment building as the change of orientation and window to wall ratio among $46m^2$ and $84m^2$ type. In conclusion, when reducing the window to wall ratio, energy demand was reduced, except when the orientation of the building was between from +10 to -20 from the south.

  • Purpose: Due to an ever more interconnected global commercial environment, the role of SMEs from emerging markets has attracted considerable attention in business literature of late. Reinforced by strategic management theory, this study builds on aspects such as entrepreneurial orientation and dynamic capabilities to construct and test a framework that focuses on exploring their associations with export performance. Research design, data and methodology: To contribute further towards a deeper understanding of these markets, the current study empirically tests a model using data collected from 225 exporting firms located throughout South Africa. Results: The results from the data analysis show that entrepreneurial orientation contributes significantly towards improving the performance of South African SMEs. Additionally, this study integrates three dynamic capabilities in the strategy-performance relationship to test their interacting effects on the correlation between entrepreneurial orientation and export performance. Further findings advocate support for relationship-based capabilities playing a moderating role between entrepreneurial orientation and the exporting performance of small and medium firms emanating from emerging markets. Conclusions: Findings provide substance to the argument that entrepreneurship, as a strategy-making process, leads to export performance in emerging nations. Especially, this study provides several suggestions as to how small and medium-sized organizations can develop their exporting performance based on the research findings.

  • Market orientation emphasizes the capability of a firm to learn customers, competitors, and inter-functional coordination and to use this market intelligence of creating superior value in the marketplace. In recent years, academic and practitioner interest has focused on market orientation and factors that engender this orientation in organizations. Although the merits of maintaining organizational learning have been extensively discussed in the literature, little studies examine the empirical link between market orientation and organizational learning which has a strong relation with it. The objective of this study is to assess the relationship between organizational commitment, market orientation, and organizational learning and presents more close a relational structure. The relationships between organizational commitment(OC), market orientation (MO), and organizational learning(OL) were analysed by structural equation modelling. a structure of OC-MO-OL is supported by our research and past literatures.

  • The aim of this study was to identify students' views on the orientation of science and to investigate the relationship between their views and decision-making on socio-scientific issues (SSI). In this study, 27 university students attending a science course were asked to discuss four controversial issues: the Toyota recall, the green car, the global warming and swine influenza (influenza A (H1N1)). The study was comprised of two stages. At the first stage, we examined students' views on the nature of science and on the orientation of science with the open-ended questionnaire based on VNOS and VOSTS. While they held relatively similar views on the nature of science, their views on the orientation of science were distinct as pragmatic, intrinsic, communal and ethical views. At the second stage, to examine the role of their views on the orientation of science in decision-making, we selected four students who had similar views on NOS but different views on the orientation of science. The four students were selected from each group of views on the orientation of science and their decision-making processes were analyzed following grounded theory. Across SSIs, they relied upon their views on the orientation of science as the strategies for decision, though considered different perception, and causal and contextual conditions. This study indicates that understanding students' views on the orientation of science would be helpful for achieving scientific literacy for informed decision.
