Investigating the Effect of ADDIE Model on the Effectiveness of Clinical Education of Operating Room Students

AbstractIntroduction: As a clinical setting, the operating room (OR) is also a complicated system; there are a lot of contrasts and complexities between the OR environment and other clinical areas regarding the teaching and learning process. Effective teaching in the operating room is clearly one of the most important and yet most challenging and difficult-to-define tasks for any educator. There is no instructional model for operating room students. This study was aimed at developing a clinical education model for OR students, in accordance with ADDIE model.Methods: The ADDIE model was used to guide the development of clinical education in five University of Medical Sciences. The ADDIE model includes five steps of Analysis, Design, Development, Implementation, and Evaluation. Qualitative method, literature review and curriculum assessment was used to generate five step ADDIE model.Results: Conceptual model “gaining of clinical competence and approval” was appeared in analysis step ADDIE model. Presenting educational objectives, learning communication skills and teamwork, performing objective evaluation, administering a comprehensive test, as well as learning from surgical team members and peers were also specified.Conclusions: The findings of the research, in relation to the clinical training of students in the operating room field, indicated the uniqueness of the clinical environment of the operating room and how the student copes with the different conditions of the environment and teamwork in the operating room. The present research led to the design of a model based on the general pattern of educational design(ADDIE model). ADDIE provides a model for common understanding of teamwork to increase aptitude and professional competence of operation room students.

Review of mismatch mitigation techniques for PV modules

The installation of photovoltaic (PV) systems is continuously increasing in both standalone and grid-connected applications. The energy conversion from solar PV modules is not very efficient, but it is clean and green, which makes it valuable. The energy output from the PV modules is highly affected by the operating conditions. Varying operating conditions may lead to faults in PV modules, e.g. the mismatch faults, which may occur due to shadows over the modules. Consequently, the entire PV system performance in terms of energy production and lifetime is degraded. To address this issue, mismatch mitigation techniques have been developed in the literature. In this context, this study provides a review of the state-of-the-art mismatch mitigation techniques, and operational principles of both passive and active techniques are briefed for better understanding. A comparison is presented among all the techniques in terms of component count, complexity, efficiency, cost, control, functional reliability, and appearance of local maximums. Selected techniques are also benchmarked through simulations. This review serves as a guide to select suitable techniques according to the corresponding requirements and applications. More importantly, it is expected to spark new ideas to develop advanced mismatch mitigation techniques.</p

The Role of Occupational Therapy in Primary Care with Older Adults

The older adult population in the United States (U.S.) is projected to increase over the next 30 years (United States Census Bureau, 2014). With that, nearly two-thirds of older adults in the U.S. are diagnosed with at least one chronic health condition (Center for Disease Control and Prevention [CDC], 2016b). These findings highlight a need for more specialized services for this population. Primary care is one sector of healthcare service delivery operating within the U.S. healthcare system. Presently, occupational therapy services are limited in primary care settings as defined in this scholarly project. Occupational therapy services have demonstrated efficacy in providing cost-effective care that can reduce hospitalizations, enhance quality of life, delay effects of aging, and promote disease prevention (Clark et al., 2012; Jackson, Carlson, Mandel, Zemke, & Clark, 1998; Muir, 2012; Rogers, Bail, Lavin, & Anderson, 2016). Therefore, occupational therapists are well-equipped to provide interventions to older adults in order to prevent the progression of chronic disease to a point at which functional performance in valued daily occupations is limited. A review of the literature helped to guide the development of this scholarly project and the Occupational Adaptation model assisted in organizing the product (Turpin & Iwama, 2011). The overall aim of this scholarly project is to advocate for the establishment of occupational therapy positions within primary care settings with older adults experiencing chronic conditions in order to enhance the preventive services being provided to this at-risk population, benefiting both the client and overall healthcare system. The product includes advocacy materials as well as occupational therapist and client guides to promote the inclusion of occupational therapy in primary care settings working with older adults experiencing chronic conditions. It is anticipated that the occupational therapist guide will assist practitioners in implementing interventions that target the specific needs of each client. With that, the client guide is anticipated to provide the therapist and client with materials that can be easily accessed and utilized throughout the intervention process. We anticipate that our scholarly project will facilitate the wellness trajectory within our U.S. healthcare system for the improvement of quality of life for our older adult population

User\u27s Guide to MBC3: Multi-Blade Coordinate Transformation Code for 3-Bladed Wind Turbine

The dynamics of wind turbine rotor blades are conventionally expressed in rotating frames attached to the individual blades. The tower-nacelle subsystem though, sees the combined effect of all rotor blades, not the individual blades. Also, the rotor responds as a whole to excitations such as aerodynamic gusts, control inputs, and tower-nacelle motion—all of which occur in a nonrotating frame. Multi-blade coordinate transformation (MBC) helps integrate the dynamics of individual blades and express them in a fixed (nonrotating) frame. MBC involves two steps: transforming the rotating degrees of freedom and transforming the equations of motion. Reference 1 details the MBC operation. This guide summarizes the MBC concept and underlying transformations

An Overview of Data Storage in Cloud Computing

Dynamic safety assessment of a nonlinear pumped-storage generating system in a transient process

This paper focuses on a pumped-storage generating system with a reversible Francis turbine and presents an innovative framework for safety assessment in an attempt to overcome their limitations. Thus the aim is to analyze the dynamic safety process and risk probability of the above nonlinear generating system. This study is carried out based on an existing pumped-storage power station. In this paper we show the dynamic safety evaluation process and risk probability of the nonlinear generating system using Fisher discriminant method. A comparison analysis for the safety assessment is performed between two different closing laws, namely the separate mode only to include a guide vane and the linkage mode that includes a guide vane and a ball valve. We find that the most unfavorable condition of the generating system occurs in the final stage of the load rejection transient process. It is also demonstrated that there is no risk to the generating system with the linkage mode but the risk probability of the separate mode is 6 percent. The results obtained are in good agreement with the actual operation of hydropower stations. The developed framework may not only be adopted for the applications of the pumped-storage generating system with a reversible Francis turbine but serves as the basis for the safety assessment of various engineering applications.National Natural Science Foundation of ChinaFundamental Research Funds for the Central UniversitiesScientific research funds of Northwest A&F UniversityScience Fund for Excellent Young Scholars from Northwest A&F University and Shaanxi Nova progra

Life cycle assessment (LCA) applied to the process industry: a review

Purpose : Life cycle assessment (LCA) methodology is a well-established analytical method to quantify environmental impacts, which has been mainly applied to products. However, recent literature would suggest that it has also the potential as an analysis and design tool for processes, and stresses that one of the biggest challenges of this decade in the field of process systems engineering (PSE) is the development of tools for environmental considerations. Method : This article attempts to give an overview of the integration of LCA methodology in the context of industrial ecology, and focuses on the use of this methodology for environmental considerations concerning process design and optimization. Results : The review identifies that LCA is often used as a multi-objective optimization of processes: practitioners use LCA to obtain the inventory and inject the results into the optimization model. It also shows that most of the LCA studies undertaken on process analysis consider the unit processes as black boxes and build the inventory analysis on fixed operating conditions. Conclusions : The article highlights the interest to better assimilate PSE tools with LCA methodology, in order to produce a more detailed analysis. This will allow optimizing the influence of process operating conditions on environmental impacts and including detailed environmental results into process industry
