Mobile Phone Usage

Sound is a common means to give feedback on mobile devices. Much research has been conducted to examine the learnability and user performance with systems that provide audio feedback. In many cases a training period is necessary to understand the meaning of a specific feedback, because their functional connotation may be ambiguous. Additionally, no standardized evaluation method to measure the subjective quality of these messages has been established; especially regarding the affective quality of feedback sounds. The authors describe a series of experiments to investigate the affective impression of audio feedback on mobile devices as well as their functional meaning under varying contexts prototypical for mobile phone usage. Results indicate that context influences the emotional impression and that there is a relation between affective quality and functional appropriateness. These findings confirm that emotional stimuli are suitable as feedback messages in the context of mobile HCI and that context matters for the affective quality of sounds emitted by mobile phones.

This study is motivated by the fact that there are currently no widely used applications available to quantitatively measure a power wheelchair user’s mobility, which is an important indicator of quality of life. To address this issue, we propose an approach that allows power wheelchair users to use their own mobile devices, e.g., a smartphone or smartwatch, to non-intrusively collect mobility data in their daily life. However, the convenience of data collection brings substantial challenges in data analysis because the data patterns associated with wheelchair maneuvers are not as strong as other activities, e.g., walking, running, etc. In addition, the built-in sensors in different mobile devices create significant heterogeneity in terms of sensitivity, noise patterns, sampling settings, etc. To address the aforementioned challenges, we developed a novel approach composed of algorithms that work collaboratively to reduce noise, identify patterns intrinsic to wheelchair maneuvers, and finalize mobility analysis by removing spikes and dips caused by abrupt maneuver changes. We conducted a series of experiments to evaluate the proposed approach. Experimental results showed that our approach could accurately determine wheelchair maneuvers regardless of the models and placements of the mobile devices.

A study was carried out in six beet sugar factories in France during the 2012/13 sugar campaign. The objective was to assess the optimal dosage of formaldehyde solutions at specific process stages and in different existing factory set-ups in order to obtain the desired effect on microbial populations, without interference with the quality of the products. In addition harmlessness regarding consumer health was to be demonstrated. A series of experiments was conducted resulting in new data allowing refreshment of common knowledge and references existing regarding the use of formaldehyde solutions in the sugar industry. The effectiveness and convenience for controlling microbiological activity in beet sugar manufacture was assessed. Formaldehyde reduces sugar losses and protects in-process products without harming their further use, such as for ethanol production.

Cpr Quality

Although the use of audio feedback with devices such as metronomes during cardiopulmonary resuscitation (CPR) is a simple method for improving CPR quality, its effect on the quality of pediatric CPR has not been adequately evaluated. In this study, 64 healthcare providers performed CPR (with one- and two-handed chest compression (OHCC and THCC, respectively)) on a pediatric resuscitation manikin (Resusci Junior QCPR), with and without audio feedback using a metronome (110 beats/min). CPR was performed on the floor, with a compression-to-ventilation ratio of 30:2. For both OHCC and THCC, the rate of achievement of an adequate compression rate during CPR was significantly higher when performed with metronome feedback than that without metronome feedback (CPR with vs. without feedback: 100.0% (99.0, 100.0) vs. 94.0% (69.0, 99.0), p < 0.001, for OHCC, and 100.0% (98.5, 100.0) vs. 91.0% (34.5, 98.5), p < 0.001, for THCC). However, the rate of achievement of adequate compression depth during the CPR performed was significantly higher without metronome feedback than that with metronome feedback (CPR with vs. without feedback: 95.0% (23.5, 99.5) vs. 98.5% (77.5, 100.0), p = 0.004, for OHCC, and 99.0% (95.5, 100.0) vs. 100.0% (99.0, 100.0), p = 0.003, for THCC). Although metronome feedback during pediatric CPR could increase the rate of achievement of adequate compression rates, it could cause decreased compression depth.

The article is devoted to the substantiation of the procedure for testing complex technical systems to assess the probability of performing the task, taking into account a priori data obtained from the results of modeling, field tests of components and prototypes, operation of analogues, etc. The conditions for the formation of a combined sample consisting of field experiments and experiments counted on the results of modeling are justified. Data uniformity is checked using the Student's criterion. The minimum volume of full-scale tests is determined by the requirement of equality of the amount of Fischer information about the estimated parameter obtained during full-scale tests and at the expense of a priori data A strategy for conducting field experiments is proposed, in which the required quality of evaluating the probability of completing the task is achieved with the minimum possible number of field experiments. At the first stage, a series of experiments with a volume equal to half of the required sample size is performed. At the second stage, the experiments are conducted sequentially with an assessment after each experiment of the requirements for the amount of information about the evaluated parameter and for the uniformity of data. Experiments are terminated when the specified requirements are met, and then a combined sample is formed, which is used to evaluate the probability of the system performing the task. A model example is considered. The estimation of the gain in the number of experiments performed at different probability values was carried out.

Abstract For many generations, works of art have been a source for experiencing beauty. They add to the wealth of our culture because they convey universal themes and values. In this study, we treat paintings as a stimulus for personal story-telling. The purpose was to explore the affective quality of personal meanings present in autobiographical narratives. Our findings show that subjective ratings of the beauty of figurative paintings are linked with the quality and theme of personal experiences recalled in response to viewing them, but not related to the length of the story. ‘Beautiful’ pictures elicit descriptions of desirable experiences associated with passive contemplation and satisfied self-enhancement motive. ‘Non-beautiful’ pictures call to mind difficult experiences linked with frustration. The experts formulated longer self-narratives inspired by paintings rated beautiful in comparison to laypersons, and laypersons formulated longer self-narratives inspired by paintings rated not beautiful in comparison to experts. The results are discussed in connection to the nature of the aesthetic experience and specificity of personal maenings.

ABSTRACT Background Approaches for teaching neurology documentation include didactic lectures, workshops, and face-to-face meetings. Few studies have assessed their effectiveness. Objective To improve the quality of neurology resident documentation through payroll simulation. Methods A documentation checklist was created based on Medicaid and Medicare evaluation and management (E/M) guidelines. In the preintervention phase, neurology follow-up clinic charts were reviewed over a 16-week period by evaluators blinded to the notes' authors. Current E/M level, ideal E/M level, and financial loss were calculated by the evaluators. Ideal E/M level was defined as the highest billable level based on the documented problems, alongside a supporting history and examination. We implemented an educational intervention that consisted of a 1-hour didactic lecture, followed by e-mail feedback “paystubs” every 2 weeks detailing the number of patients seen, income generated, income loss, and areas for improvement. Follow-up charts were assessed in a similar fashion over a 16-week postintervention period. Results Ten of 11 residents (91%) participated. Of 214 charts that were reviewed preintervention, 114 (53%) had insufficient documentation to support the ideal E/M level, leading to a financial loss of 24% ($5,800). Inadequate documentation was seen in all 3 components: history (47%), examination (27%), and medical decision making (37%). Underdocumentation did not differ across residency years. Postintervention, underdocumentation was reduced to 14% of 273 visits (P &lt; .001), with a reduction in the financial loss to 6% ($1,880). Conclusions Improved documentation and increased potential reimbursement was attained following a didactic lecture and a 16-week period in which individual, specific feedback to neurology residents was provided.
