  Background and Objective: Aging process has been known to associated with cardiac abnormality. Fucoidan and fucoxanthin have been suggested as safe supplement. In this study, fucoidan in combination with fucoxanthin were used to enhance the impaired cardiac systolic and diastolic function in aging canine model. Materials and Methods: Aging canines were fed with fucoidan (125 mg kg–1) and fucoxanthin (125 mg kg–1) for 3 months. Echo cardiography was used to compute Tei index and related parameter such as E / E`, E` / A` and isovolumetric relaxation time (IVRT), isovolumetric contraction time (IVCT) was calculated using the Doppler model. T-Test was used to compare echo parameters. Data were displayed as Mean±SD. SPSS was used for statistical analysis. Results: IVRT and IVCT were shortened with 15.78±3.71 and 24.53±6.71%, respectively after fucoidan and fucoxanthin treatment, suggested that these two phytochemical compounds have cardioprotective effects in aging canine subjects with degenerative valve disease. Conclusion: After 3 consecutive months of Fucoidan and fucoxanthin usage, the cardiac function of aging canine was improved. Fucoidan and fucoxanthin may be considered as a potential treatment or supplement to aging canine subjects with abnormality in cardiac function.

  This study treated the high-tech industry as the subjects and probes into the correlation among organizational cultures, information technology involvement, degrees of knowledge management activities and performance of new product developments. The subjects of this research were Taiwan’s high-tech firms in the Hsinchu Science-Based Industrial Park and Southern Taiwan Science-Based Industrial Park. The respondents were the project members or senior managers involved, currently or previously, in the development of new products. The design of the questionnaire items was based on literature review. The results reveal that the higher the degrees of information technology involvement and organizational cultures, the more significant the influence on the implementation of knowledge management activities and performances of new product developments. The better the implementation of knowledge management activities, the stronger the positive influence on the performance of new product developments. Different organization cultural types (i.e., rational cultures, hierarchical cultures, group cultures and developmental cultures) do not report any significantly different levels of influence on the implementation of knowledge management activities or performance of new product developments. This study suggested that to enhance the performance of new product developments, it is necessary to strengthen information technology involvement and the implementation of knowledge management activities, as well as to integrate the characteristics of the four cultural types in the competing values framework and to enhance the implementation under these four cultural types.

  This study probes into the influences of implementation strategies of Total Quality Management (TQM) and organizational culture on execution degree of TQM activities and the effect of execution degree of TQM activities on operational performance. The subjects of this research were Taiwan’s high-tech firms in the Hsinchu Science-Based Industrial Park and Southern Taiwan Science-Based Industrial Park. Quality management supervisors in the companies were the target respondents. The design of the questionnaire items was based on literature review. The research findings reveal that implementation strategies of TQM (cost leadership strategy and differentiation strategy) have significant influence on the execution degree of TQM activities; Organizational culture significantly influences execution degree of TQM activities; TQM activities execution degree significantly influences operational performance (quality performance, financial performance and inventory management performance). When reinforcing the operational performance, the firms should first enhance the execution of TQM activities. In order to significantly enhance execution degree of TQM activities, the firms can improve the implementation of cost leadership and differentiation strategy and combine the characteristics of four cultures (group culture, developmental culture, hierarchical culture and rational culture).

  Virtual Classroom (VC) not only has the function to replace a traditional classroom but also has less expense related to transportation, building new facilities, or the maintenance or repair of existing facilities. This study proposes some factors which influence the success of E-teaching. The subjects include students who have experience of attending related e-teaching system. Data were collected on May 2010. Subjects were in age from 18-24 years old. SPSS Amos 18 is used for data analysis and it shows that government policy, school regulation, student experience are important roles in guiding a successful e-teaching activity. This study also confirms that User Experience is the most significant determinant that directly affects the effect of user interaction and knowledge exchange in e-teaching practice. When users get greater experience of IT operation skill, their feelings about E-teaching practice will be more successful. The adoption of E-teaching would be more successful when users gain greater skills at IT operation. Fulfilled E-classroom application is able to help the elite or mass stage of higher education system moving to the universal stage because per student cost of VC is quite lower. The suggestion of E-classroom implementation is also helpful for the expansion of higher education in some countries, such as Asian countries (China, Mongolia, Thailand, the Philippines and Indonesia) or other elite stage countries.

  Nintendo Wii is one of current most popular indoor recreational activities. The birth of Wii brought with it a new form of game machine that has had a major impact on the world of information technology industry. Because it combines the characteristics of recreation, leisure and interaction, the customer can both pursue exercise and experience virtual reality simultaneously. Wii need to connect to TV screen and also need a large room to play, so most of families put it in the living room. However, every family’s living room size and the TV screen size are quite different. Therefore, this study aimed to evaluate the effect of screen size and viewing distance on game performance and subjective rating and providing the user with a reference for choosing proper screen. This research adopts three different size screens and three different viewing distances to simulate all activities. Fifty participants are recruited to play the Wii. Each individual's score and subjective rating are recorded with consideration of the influence of gender and age. By the experimental results, it is found that both screen size and viewing distance are the factors affecting game performance. Bigger screen and farther viewing distance lead to higher game performance and subjective ratings, but the participant's fundamental data, such as age, gender, experience, frequency and response ability, have no any influences on game performance.

  This study treated the hospitals as subjects and probed into the correlation among market orientation, organizational learning, types of operational strategies, organizational culture, executive degree of knowledge management activities and operational performance. The samples were 466 qualified hospitals in hospital evaluation and teaching hospital evaluation from 2007 to 2011 registered in Department of Health, Taiwan. The researcher collected related data by distributing questionnaires through mails. The subjects were the supervisors in the hospitals. The results found that the higher executive degree of knowledge management was, the more significant and positive effect it would be on operational performance; the higher the executive degrees of cost leadership, marketing differentiation and innovation differentiation strategy were, the more significant and positive effect it would be on executive degree of knowledge management; the higher the executive degrees of organizational learning and market orientation were, the more significant and positive effect it would be on executive degree of knowledge management; the higher the executive degrees of rational culture, hierarchical culture, group culture and developmental culture were, the more the effect it would be on executive degree of knowledge management. Thus, this study suggests that hospitals should enhance organizational learning, market orientation and knowledge management execution to improve operational performance. Hospital management should value rational culture, hierarchical culture, group culture, developmental culture and initiate cost leadership and differentiation implementation strategies.

  This study proposes a new decision analysis methodology that identifies the core order-winner criteria problems. A modified Importance-Performance Analysis (IPA) and multiple regression analysis are applied to define the implicit importance of quality characteristics and overall satisfaction. Gap analysis is used to identify the performance of quality characteristics. Decision making trial and evaluation laboratory (DEMATEL) is used to correlate the interrelationship among the quality characteristics. This methodology better defines the importance and priority over quality characteristic improvements and solves the practically complicated, contradictory problems with the least resources. This study performs empirical research into the Taiwanese computer industry and explains the application and benefits of the modified IPA and DEMATEL.
