Impact Analysis of Facility Failures on Healthcare Delivery Process: Use Case-Driven Approach
No full textThe healthcare industry is growing in complexity, and providing a safe healthcare setting increases the challenges for many healthcare facility managers. Most facility information is not linked to the healthcare delivery process, making it difficult to identify interactions and overlaps that may have critical implications for the smooth operation of the healthcare delivery process and patient safety. This paper focused on an impact analysis of facility failures on the healthcare delivery process and involved a combination of research methods including a case study, interviews with key healthcarepractitioners as part of a case study in a major hospital, and cognitive walk-throughs with domain experts. The interactions of facility information with the healthcare delivery process helped to identify critical facility failures through planned and unplanned safety events. Use cases, use-case diagrams, scenario interaction diagrams, and failure mode and effects analysis (FMEA) were developed to learn and assess the functionality of the healthcare system communication related to the planned and unplanned events, and a number of factors associated with the facility failures were recognized
Global Warming/ Climate Change: Involving Students Using Local Example
No full textThe current political climate has made it apparent that the general public does not believe in global warming. Also, there appears to be some confusion between global warming and climate change; global warming is one aspect of climate change. Most scientists believe there is climate change and global warming, although, there is still doubt among students on global warming. Some upper level undergraduate students are required to conduct water level/temperature measurements as part of their course grade. In addition to students having their individual projects, the various classes also utilize a well field within a wetland on campus to conduct group projects.
Twelve wells in the well field on campus are used regularly by students to measure the depth of groundwater, the temperature of the waters and other basic water chemistry parameters like pH, conductivity and total dissolved solid (TDS) as part of the class group project. The data collected by each class is added to data from previous classes. Students work together as a group to interpret the data. More than 100 students have participated in this venture for more than 10 years of the four upper level courses: hydrogeology, environmental and urban geology, environmental conservation and wetlands. The temperature trend shows the seasonal variation as one would expect, but it also shows an upward trend (warming). These data demonstrate a change in climate and warming. Thus, the students participated in data collection, learn to write report and present their result to their peers in the classrooms
Response of Massasaugas (Sistrurus catenatus) to habitat alteration from timber harvest and fire near their northern range limit
No full textLandscape modifications are often implemented to improve habitat quality for a variety of imperiled species. However, relatively little is known regarding how rare snakes, including eastern massasaugas Sistrurus catenatus, respond to such manipulations. Between 2002 and 2014 we used radio telemetry to monitor short-term (1-2 years) and \u3e5 years response to experimental clear-cutting in northern Michigan for this species. More recently, a fire in 2010 occurred within habitat historically used by massasaugas during activity periods and for overwintering. Both habitat alterations removed vegetative structure, potentially altering the quality of basking habitat. Use of clear cut habitat by telemetered snakes was lower than would be expected by chance during the first two years. However, use increased over time and included multiple successful parturition events. Additionally, massasaugas continued to use recently burned habitat for overwintering and parturition. Our findings suggest that massasaugas are resilient to landscape changes and may benefit from habitat alterations
CPTu-based Enhanced UniCone Method for Pile Capacity
No full textThe UniCone direct piezocone method by Eslami and Fellenius (1997) for evaluating the axial capacity of pile foundations is reviewed and improved means of evaluating the soil resistance factors are recommended. This method uses all three piezocone penetration test (CPTu) readings in a soil behavioral type (SBT) classification chart and provides estimations of axial pile capacity for a wide variety of pile types installed in different assortments of geomaterials. In this paper, the earlier method is improved using a dataset of 153 pile load tests and CPTu soundings from 52 worldwide sites. An alternative soil classification system using the CPT material index Ic is used to provide improved correlations of higher reliability via continuous functions for estimating the side and base capacity components of driven and jacked piles, and drilled shafts. An analysis is also included to test the performance of the newly proposed design formulations. Finally, a simplified flowchart is presented for convenient application of the enhanced expressions
A Visualization Platform for Internet of Things in Manufacturing Applications
No full textPurpose – The purpose of this paper is to present a visualization platform to control and monitor wireless sensor networks (WSNs) inmanufacturing applications. Design/methodology/approach – To make the platform flexible and versatile, a modular framework is adopted inmodeling and visualizing WSNs. The Eclipse programming environment is used to maximize the scalability and adaptability of the platform. A set of the core functional modules have been designed and implemented to support the system operation. The platform is validated through a case study simulation. Findings – The platform is capable of accommodating different operating systems such as Windows and Linux. It allows integrating new plug-ins developed in various languages such as Java, C, C++, and Matlab. The Graphic User Interface has been applied to process and visualize the acquired real-time data from a WSN, and the embodied methodologies can be used to predict the behaviors of objects in the network. Research limitations/implications – The work has shown the feasibility and potential of the proposed platform in improving the real-time performance of WSN. However, the number of the developed functional modules is limited, and additional effort is required to develop sophisticated functional modules or sub-systems for a customized application. Practical implications – The platform can be applied to monitor and visualize various WSN applicationsin manufacturing environments such as automated workcells, transportation systems, logistic, and storage systems. Originality/value – The work is motivated by the scarce research on the development tools for monitoring and visualization of WSNs in manufacturing applications. The proposed platform serves for both of system developers and users. It is modularized with a set of core functional modules; it can be extended to accommodate new functional modules with a minimal effort for a different application
