Purpose: To enhance the existing Bachelor of Science (BSc) in nursing curriculum through integration of evidence-based practice (EBP) and teaching of critical thinking skills. Materials and Methods: A needs analysis was conducted using a five-phased approach to review the BSc in nursing Curriculum. Kern’s six-step model was adapted and introduced through a series of workshop exercises that highlighted the application of each step: 1) Desk review of the BSc curriculum offered globally;2) Administration of the needs assessment questionnaire to key informants;3) Strengths, weakness, opportunities and threat analysis;4) Consultative meeting with major stakeholders;5) Curriculum review. Results: The five-phased approach established some gaps in existing curricula, and identified critical core competences and best practices in integrating EPB and critical thinking in the BSc undergraduate curriculum and some “A” level content that was not in tandem with the practice of nurses. New courses were developed to support students in academic writing and enhance professionalism and duration of training was reduced from 5 to 4 years. Conclusion: The process demonstrated that BSc curriculum review, in fact, should be thoroughly scrutinized to encourage positive changes to the curriculum, provide opportunities for team building and the development of leadership skills and a whole-of course perspective on the curriculum.展开更多

The first chapter of the book introduces various basic concepts of structural optimization through several illustrative examples. Chapter 2 is devoted to a comprehensive review of math- ematical programming methods, including classical methods such as the simplex method, the （SLP） method, the interior point method and relatively new approaches such as genetic algo- rithms. The third chapter presents the main topic of this book, the SLP methods based on the incremental equations of structures. Some useful techniques in implementation of SLP, including the move limit, scaling and active constraint identifying, are discussed. In chapter 4, classical optimality criterion approaches, including the fully stress approach for truss struc- tures and its extensions for membrane and plate structures, are presented with demonstrative examples. The remaining chapters develop an overview of structural optimization problems, among which are dynamic optimization, multi-criterion optimization, earlier work on the op- timal layouts of plates, as well as some practical issues in general size and shape optimization problems.展开更多

With the complexity, walking has been widely investigated in order to identify the pattern of multi-segment movement and reveal the control mechanism. The degree of freedom and dimensional properties provide a view of the coordinative structure during walking, which has been extensively studied by using dimension reduction technique. In this paper, the studies related to the coordinative structure, dimensions detection and pattern reorganization during walking have been reviewed. Principal component analysis, as a popular technique, is widely used in the processing of human movement data. Both the principle and the outcomes of principal component analysis were introduced in this paper. This technique has been reported to successfully reduce the redundancy within the original data, identify the physical meaning represented by the extracted principal components and discriminate the different patterns. The coordinative structure during walking assessed by this technique could provide further information of the body control mechanism and correlate walking pattern with injury.展开更多

Some of these techniques using topography are used in several fields (civil engineering, geodesy, topography, mechanics, nuclear engineering, hydraulics, physics, etc.). These topometric techniques have undergone major changes as a result of technological advances, growing needs in the monitoring of movements or deformations, increased requirements and new challenges. The methodology adopted depends on the measuring instrument used, the parameters to be estimated and access to the area to be measured. There are two types of methods: destructive and non-destructive. In addition to the visual method, they can also be classified as mechanical, physico-chemical, dynamometric, electrophysical and geometric. The estimated parameter varies according to the methodology adopted. It can be defined by coordinates, distances, potential, electrical resistance, etc.展开更多
