Keyboard design deficiencies of mobile bar code scannersLong, Myra D. 24 March 2006 (has links)
The use of mobile bar code scanners is expanding to markets beyond popular
manufacturing uses, such as healthcare, environmental testing and professional
services. The successful interaction of users with mobile bar code scanners is of great
importance from a business and technology perspective as well as from the user
standpoint. Interaction problems associated with these devices may cause errors in
data collection and affect job performance due to frustration, resulting in a potential
impact on internal costs.
The primary objective of this research was to develop design guidelines for the
reengineering of keyboard designs for mobile bar code scanners. A secondary
objective was to determine the effectiveness of current bar code scanner designs and
how they can be related to other mobile technologies to develop a link across research
areas. To accomplish these objectives, three different mobile bar code scanner
keyboard designs were investigated: multiple-alphabetical, single-alphabetical and
single split-Qwerty. A total of 42 subjects (18 females and 24 males) were recruited to
participate in the experiment that was conducted to validate the research hypotheses.
Time and accuracy data were recorded during the experiment and workload/subjective
questionnaires were given to each participant following interaction with the different
mobile bar code scanners.
The following conclusions were reached based on the experimental results and
are considered the major contributions of this research. First, an alphabetically laid
out keyboard with multiple keys results in more time to find a character, a higher
percentage of time spent typing incorrect lines, and a higher error rate than an
alphabetically laid out keyboard with single keys. Perceived workload was also higher
for a keyboard with multiple keys versus one with single keys. Second, no significant
differences were found in the time to find a character, the percentage of time spent
typing incorrect lines, and the error rate between keyboards with single keys, whether
they are laid out alphabetically or in a split-Qwerty design. Finally, training a user on
how to use a specific mobile bar code scanner keyboard layout often results in higher
character rates, less time spent typing incorrect lines, and a lower error rate. / Graduation date: 2006

Improving the Nursing Practice Environment With Point of Care Specimen CollectionSaathoff, April Marie 01 January 2017 (has links)
Specimen collection and identification errors are a significant problem in healthcare, contributing to incorrect diagnoses, delayed care, lack of essential treatments, patient injury or death, increased length of stay and increased healthcare costs, and decreased patient satisfaction. The purpose of the project was to evaluate the implementation of specimen collection technology with barcode scanning and bedside label printing in the maternal child health division of a community teaching hospital. The project was driven from Donabedian's quality framework for healthcare implementations, indicating that evaluating the quality of health care can be drawn from the categories of structure, process, and outcomes. The project featured a quantitative analysis with a pretest-posttest design. Mislabeled specimen rates and collection turnaround times were generated from laboratory quality data and measured before, during, and after implementation of specimen collection technology. Data analysis using an independent samples t test in SPSS 17.0 compared the changes in the mean scores of specimen collection turnaround times and mislabeled specimen rates. Mislabeled specimen percentages in all areas decreased from 0.0250% preimplementation to 0.0023% postimplementation with a p value less than 0.001. Collection turnaround times greater than 60 minutes decreased following implementation of specimen collection technology by 22% with a p value less than 0.001. The implementation of specimen collection technology has positive implications for social change, including the expectation that as technology is proven to significantly improve the safety and quality of laboratory collections, there will be a mandate for implementation of safer collection processes in healthcare.

Olympic Logistics Centers and their Adjustment to Specific Requirementsand Distribution Applications : Comparing the Olympic SummerGames 2000-2008Strehlow, Anett, Rehage, Katja January 2012 (has links)
Problem: Since there is not much inside information available, the problem that will be handled by this thesis is the coordination of warehousing activities within the logistics centers put to use by the Olympic Summer Games from 2000 to 2008. A special attention is given to certain requirements such as layout, capacity management, ownership and distribution applications. Purpose: The purpose of this thesis is based on warehouse requirementsand their specific adjustment to the Olympic Summer Games, further emphasizing on distribution applications influencing the capacityand ownership. Theory: The theoretical section touches upon event logistics, the Olympic Games and more importantly, logistics centers as a generic termfor distribution facilities and warehouses. Further, types of warehouses, capacity management, ownership and distribution applications are examined in order to be able to compare the various Games. Method: The method for this research is based on a case study conducted by semi-structured interviews with several people involved in the logistics organization of the Games. All interviews are conducted over the telephone and analyzed accordingly. However, secondary data was of high importance due to the limited number of interview respondents. Conclusion: All analyzed features of a warehouse facility had to be more efficiently and effectively performed in order to serve the great approach for the Olympic Summer Games. The implementation of distribution applications was not sophisticated enough to benefit capacity savings. The leased ownership situation and outsourcing to third party logistics providers were advantageous, but did not further influence the planning and utilization phase of the Olympic Games.
