The school, founded in 1950 as a junior college of English literature, is today a comprehensive university comprising eleven colleges that serves nearly 30,000 students via four campus sites .Tamkang University enjoys widespread recognition as Taiwan's oldest private institution of higher learning and one of its most distinguished. The school ranks 9th on comprehensive measures by Taiwan's Ministry of Education and in the top 50 universities in Asia. Over 28,000 students of fifty nationalities form the diverse student body of the school. The school has partnerships with over a hundred sister universities in 28 countries. The university's main campus in historic Tamsui is noted for its scenery. Casually, members of the university community call themselves 'Tamkangians.' Wikipedia.

We show how all the quantal systems related to the exceptional Laguerre and Jacobi polynomials can be constructed in a direct and systematic way, without the need of shape invariance and Darboux-Crum transformation. Furthermore, the prepotential need not be assumed a priori. The prepotential, the deforming function, the potential, the eigenfunctions and eigenvalues are all derived within the same framework. The exceptional polynomials are expressible as a bilinear combination of a deformation function and its derivative.

An interesting discovery in the last two years in the field of mathematical physics has been the exceptional Xℓ Laguerre and Jacobi polynomials. Unlike the well-known classical orthogonal polynomials which start with constant terms, these new polynomials have lowest degree ℓ=1,2,..., and yet they form complete set with respect to some positive-definite measure. While the mathematical properties of these new Xℓ polynomials deserve further analysis, it is also of interest to see if they play any role in physical systems. In this paper we indicate some physical models in which these new polynomials appear as the main part of the eigenfunctions. The systems we consider include the Dirac equations coupled minimally and non-minimally with some external fields, and the Fokker-Planck equations. The systems presented here have enlarged the number of exactly solvable physical systems known so far. © 2010 Elsevier Inc.

This research investigated the application of knowledge maps in e-learning materials design and hypothesized that knowledge maps would be more effective than e-learning in general at improving the performance and satisfaction of e-learning. In order to test the hypotheses, we conducted an experiment with 175 participants and randomly assigned them into knowledge map-based and browse-based groups. Both groups of participants needed to acquire specific skills and knowledge to write the target ADO.NET program. In the end of each training session subjects received an assessment to understand their learning score, satisfaction level, and computer self-efficacy. Our statistical analysis result showed that knowledge map-based learning group outperformed browse-based group in these three measurements. Thus, the proposed hypotheses were supported. We concluded that if knowledge map-based materials design approach were employed novice users would acquire the ADO.NET programming in a more effective manner. In addition, the satisfaction and computer self-efficacy of users could be improved substantially as a result of knowledge map-based materials design approach. Thus, we propose that if knowledge maps are employed to adequately present the relationships of learning contents that knowledge could be better understood and learning performance could be improved. © 2009 Elsevier Ltd.

Purpose: The major obstacles of radiofrequency ablation (RFA) heat treatments are nonuniform heating in the thermal lesion and heat sinks caused by large blood vessels during treatments which could lead to high tumor recurrence in patients. The objective of this study is to help comprehend RFA heat treatment through thermal lesion formation using computer simulation, and thus to provide helpful assistance in planning RFA. Methods: RFA heat treatment is a popular "minimally invasive" treatment method for both primary and metastatic liver tumors, and the heat treatment is studied by numerical calculation. A finite difference model is used to solve all partial differential equations for a simple three-dimensional cubic geometry model. Maximum tissue temperature is used as a critical index for reaching thermal lesion during RFA. Cylindrical RF cool-tip electrode is internally cooled at constant water temperature. RFA thermal lesion is studied at various impacts by single and countercurrent blood vessel(s) traversing the thermal lesion. Several factors are considered, such as location, diameter, and orientation of the blood vessel(s) to the electrode. Results: Results show the thermal lesion size decreases as the lesion blood perfusion rate increases. And, single large blood vessel which is orthogonal to RF electrode will cause less undercooled volume in the thermal lesion than one which is parallel to RF electrode. Furthermore, convective energy may easily damage parallel vessel and its surrounding normal tissues during RFA. Small blood vessels (or larger vessels with slow blood flow rate) during RFA could form "tail-like" thermal lesion formation, which could damage vessel downstream spots. Conclusions: Studies suggested that incomplete RF tumor ablation still exists within 1 cm distance between large blood vessel and RF electrode in a liver. This could have significant impact on local tumor recurrence rates. Second, if thermally significant vessel existed inevitably within the lesion, avoiding the RF cool-tip electrode placement next to the parallel large blood vessel would have a better heat treatment during RF heating. Additionally, reduced blood flow rate could help reduce significant cooling by large blood vessel. © 2013 American Association of Physicists in Medicine.


This study is focused on the relationships among learning styles, participation types, and learning performance for programming language learning supported by an online forum. Kolb's learning style inventory was used in this study to determine a learner's learning type: 'Diverger', 'Assimilator', 'Converger', and 'Accommodator'. Social Learning Theory was also used to define four participation types. These types in turn were used to describe the learning associated with the use of online forums: 'Replier', 'Asker', 'Watcher', and 'No activity'. A total of 144 students participated in this experiment as part of a half semester ASP.NET programming language learning courses. The course contained an online forum for supporting the students' social activities and participation. In this study, 'learning score' and 'satisfaction' were used to measure learning performance. The results of this study were the following: (1) different learning styles were associated with significantly different learning scores and that the 'Accommodator' style was associated with superior learning scores; (2) participation types were also associated with significantly different learning scores and that the 'Replier' type is associated with superior learning scores; (3) learning satisfaction is not significantly different among the different learning styles or different participation types, but the average is significantly higher than average values (3.5) of 7-point Likert scale; (4) there is no significant association between learning styles and participation types. Explanations and discussions of these results are offered. Based on the results of this study, we propose that programming language learning, supported with online forums and students' active participation, increases learning performance as measured by student learning scores. © 2011 Elsevier Ltd.
