We demonstrate a new finding that the filtering-mask with merely four coefficients in the vertical and horizontal directions could be the best choice to achieve finest image sharpening. The mask's merit to better magnify highest spatial frequencies is unveiled by employing the nonlinear transfer function, which has been proved liable to reduce the overshooting effect. By use of this chosen mask, the enhanced image is capable of manifesting extreme sharpness. © 2013 Elsevier GmbH.

We demonstrate a brand-new method to sharpen a color image by using the integral mask-filtering technique. The high and low frequency messages between the target pixel and its neighbors are transferred by nonlinear functions. Both intensity and saturation factors of the HSV color system are taken into account. The obtained final image has clearer fine characteristics along with much less overshooting. © 2014 Elsevier GmbH. All rights reserved.

Conflict management is critical to project human resource and communication management. Conflict is inevitable in project and teamwork. Properly managed, a certain amount of conflicts is beneficial. However, the relationships between conflict management and team performance are inconsistent in previous studies. This study investigates the how project members' interpersonal relationships among internal members and external actors are related to the conflict solution satisfaction, and examines the effectiveness social interaction and satisfaction on the relationship between conflict management style and team performance. This study strives to make two contributions. First, this study adds to the sparse empirical evidence on the impact of social interaction ties on conflict management. Second, recent work on social interaction in organization has emphasized how social ties provide information and resource to a focal individual. We attempt to extend this concept at team level. In examining the relationship between social interaction ties and conflict solution satisfaction, and further affect the relationship among conflict management and team performance, this study provides a rationale for project managers to develop their conflict management skills.

We demonstrate a brand-new method to sharpen a color image by using a modified mask-filtering approach. The derivatives between the target pixel and its neighbors are transferred by the cubic root of a sinusoidal function instead of the traditional linear one. The obtained final image has clearer fine characteristics but much less overshooting that is usually found in the conventional technique. © 2011 Elsevier GmbH. All rights reserved.

Technology Enabled Active Learning (TEAL) is an innovative pedagogical method emphasizing active, interactive learning. It is implemented in a technology-rich, multimedia studio. The National Chung Cheng University (CCU) is the first university in Taiwan to use the TEAL studio to teach science courses. The purpose of this study is to assess the impact of TEAL on student learning at CCU, including the influence on genders and achievement levels. A quasi-experimental research was designed to conduct this study. Data sources consist of a pre-test, a post-test, and a survey. The preliminary results indicate that (1) the experimental (TEAL) students significantly outperformed the control (traditional classroom) students, (2) the experimental male students outperformed their counterpart male students, (3) the learning gain achieved by the experimental female students was more significant than that of their counterpart female students, and (4) the experimental low-achieving students achieved the highest learning gain among the different achievement-level groups. Narrowing the learning gap between different achievement levels of students through the use of this technology-enhanced learning approach appears promising. Nonetheless, continuing to improve the teaching innovation is necessary, particularly in terms of more effectively integrating technology-enabled features into teaching.

We demonstrate an extended mask-filtering approach to improve the sharpness of an image with non-uniform illumination. The proposed method comprises two different masks which cope with higher and lower spatial frequencies respectively. By using this integral algorithm, the enhanced image has much better performance than that derived from the conventional technique. © 2013 Elsevier GmbH.

We demonstrate a novel method to modify the mask-filtering approach by enlarging the gray-level difference of any two nearby pixels in an image. Derivatives are calculated in different directions respectively instead of isotropically. Some higher spatial frequencies are then selectively magnified. The final image has better sharpened fine characteristics than that enhanced by the conventional technique. © 2010 Elsevier GmbH. All rights reserved.

We demonstrate an improved mask-filtering approach by reducing the impact of the major factors that originate the overshooting phenomenon. The derivatives between the target pixel and its neighbors are transferred by nonlinear calculations instead of the traditional linear one. The obtained final image has clearer fine characteristics but much less unwanted overshooting which is usually found in the conventional techniques. © 2012 Elsevier GmbH. All rights reserved.

The function of sport shoes is to improve sport performance and reduce sports-related injuries. They are commercial products developed by combining sports technology and marketing activities. Numerous studies on research and development, material application, production process improvements, and human physiological measurements for the sport shoe market exist. However, few studies have conducted an in-depth investigation on the design of forms and external appearance for sports shoes. In this study, running shoes are used as the primary research object. In conjunction with Kansei engineering, the correlation between the form of a shoe model and the emotional reaction of consumers is examined in-depth to develop a Kansei prediction system solely for changes in the design of external forms of running shoes. First, the Kansei adjectives for running shoes are obtained and collected using questionnaire methods. Experimental samples of running shoes are developed using the Taguchi experimental design method. Surveys are then conducted using consumer Kansei questionnaires. Dimension reduction is performed on the obtained data using principle component analysis (PCA) and partial least squares (PLS). Finally, neural network (NN), PCA-NN, and PLS-NN are used to establish a predictive model. In this study, we observed that PLS is superior to PCA in performance on dimension reduction because it considers the Y information variable and encompasses causal relationships when converting the original variable X into a latent variable. Data from the PLS regression coefficients shows that the form of the sole is the most significant design factor affecting the emotional response of the consumer regarding the overall outer appearance of the running shoe. Because it is difficult to train neural networks (NNs) when numerous variables exist, the modeling efficiencies of NN with questionnaire data dimension reduction using PCA and PLS are compared. The results indicate that because the elements comprising running shoes correlate with consumer image responses, PCA has a limited ability in reducing dimensions when causal relationships between the variables are disregarded. Therefore, validation results from PCA-NN models are relatively poor. If the correlation between variables is included with PLS, the predictive capability of NNs can be effectively enhanced. The results show that PLS-NN performance in training and validation is superior to PCA-NN. Furthermore, the best predictive result is obtained from the Kansei adjective pair "clumsy-agile." The prediction accuracy rate of the PLS-NN model improves with increasing reduction performance for PLS. The predictive system developed using PLS-NN maintains stability or robustness for linear data processing and predictive capability with non-linear data. This allows sports shoe designers to provide the best reference combinations for specific product images when creating conceptual designs of novel shoe appearance. The system can present an appropriate external form of running shoe in the user interface as long as an adjective target value is provided by the designer. © 2013 Elsevier Ltd. All rights reserved.

The main purpose of this study is to verify the impacts of perceived organization support on employees' job burnout in international tourist hotels with psychological capital as mediator. Through stratified sampling method, questionnaires were sent to full-time employees with more than three months of working experience in international tourist hotels in Taiwan. Out of 400 distributed questionnaires, 352 valid responses were returned. The results show that psychological capital exerts a significantly negative impact on job burnout, simultaneously confirm the significant mediating effect of psychological capital on the relationship between perceived organization support and job burnout.
