Acoustic Sensor Networks

The recent development and deployment of Wireless Acoustic Sensor Networks (WASN) present new ways to address urban acoustic challenges in a smart city context. A focus on improving quality of life forms the core of smart-city design paradigms and cannot be limited to simply measuring objective environmental factors, but should also consider the perceptual, psychological and health impacts on citizens. This study therefore makes use of short (1–2.7 s) recordings sourced from a WASN in Milan which were grouped into various environmental sound source types and given an annoyance rating via an online survey with N=100 participants. A multilevel psychoacoustic model was found to achieve an overall R2=0.64 which incorporates Sharpness as a fixed effect regardless of the sound source type and Roughness, Impulsiveness and Tonality as random effects whose coefficients vary depending on the sound source. These results present a promising step toward implementing an on-sensor annoyance model which incorporates psychoacoustic features and sound source type, and is ultimately not dependent on sound level.

Sound distribution and background noise, is an important aspect in the making of study-purposed room. Properly distributed sound would ensure everyone in the room to hear the same quality of sound. Good sound quality is defined as a sound that did not diminish its character (sound intensity and sound clarity) significantly to its sound source. In this research, has been fabricated an in-room sound distribution measuring instrument, based on the Arduino microcontroller that equipped with nRF24L01 to be wirelessly functionated. The fabricated measuring instrument consist of 4 transmitter devices and 2 receiver devices. The transmitter devices is an Arduino Pro Mini microcontroller that equipped with nRF24L01 and a sound sensor. The receiver devices is an Arduino Nano microcontroller equipped with nRF24L01, that connected to a PC, and an Arduino Pro Mini microcontroller equipped with nRF24L01 that connected to a speaker. The fabricated measuring instrument equipped with a Python 2.7-based acquisition software to acquire data in real time and store it in CSV (Comma Separated Value) format. Test was carried out to the transmitter devices that equipped with a sound sensor and the receiver device that connected to a speaker. The transmitter devices was compared with a standard sound level meter, and showed 0,65% - 1,24% of error percentage. The test made to receiver device showed that sound intensity of 100 dB could only be achieved with frequency of 2000 Hz and 3000 Hz. On  the measurement of sound distribution, the primary data of Einstein Hall sound distribution has been obtained, with 16 sound level measuring point, 7 variations of sound source position, and 5 variations of sound source frequency.The background noise measurement of Einstein Hall of the FMIPA ULM, showed the value varied between 57 dB – 60,56 dB.

The City

On March 13, 2020, the first cases of SARS-COVID19 were detected in Uruguay. During the first weeks of the pandemic, mobility was significantly reduced with the slogan "If you can, stay home"; it was not a mandatory but voluntary confinement. After a couple of months, there was a big drop in the number of people affected by the disease. Thus, the Municipality of Montevideo, betting on a more human and walkable city, defined that the main avenue of the city had a pedestrian section on Saturday afternoons. This resulted in a greater enjoyment of the city by its inhabitants, as they had more space to walk while maintaining safe distances between people. It was also possible to promote trading, since classically Ave. 18 de Julio is also a commercial stroll. Additionally, the sound pressure levels recorded by the Municipality's stationary sound level meters located at three points along the avenue, showed the reduction of environmental sound levels in pedestrian areas, improving the acoustic quality of the walk. In this paper, sound pressure levels on Saturday afternoons at different times of the year before, during and after the initial lockdown due to the COVID-19 pandemic, are compared and discussed.

Subject. The article considers functioning and development of process flows of transportation and logistics system of a smart city. Objectives. The study identifies factors and dependencies of the quality of human life on the organization and management of stream processes. Methods. I perform a comparative analysis of previous studies, taking into account the uniquely designed results, and the econometric analysis. Results. The study builds multiple regression models that are associated with stream processes, highlights interdependent indicators of temporary traffic and pollution that affect the indicator of life quality. However, the identified congestion indicator enables to predict the time spent in traffic jams per year for all participants of stream processes. Conclusions. The introduction of modern intelligent transportation systems as a component of the transportation and logistics system of a smart city does not fully solve the problems of congestion in cities at the current rate of urbanization and motorization. A viable solution is to develop cooperative and autonomous intelligent transportation systems based on the logistics approach. This will ensure control over congestion, the reduction of which will contribute to improving the life quality of people in urban areas.

We developed and implemented an annual online survey to administer to residents exiting residency training in order to (1) assess the quality of the residency experience and (2) identify areas of strength and areas requiring improvement. Long-term goals include program planning, policy-making and maintenance of quality control. Survey content was developed from an environmental scan, pre-existing survey instruments, examination of training criteria established by the CFPC and the CanMEDS criteria established by the RCPSC. The survey included evaluation benchmarks and satisfaction ratings of program director and faculty, preparation for certification and practice, quality of life, quality of education, and work environment. The response rate was 28%. Seventy-five percent of respondents were exiting from Royal College training programs. Results of descriptive statistics determined that the overall educational experience was rated highly, with 98.9% of respondents satisfied or very satisfied with their overall patient care experience. Ninety-six percent of respondents were satisfied or very satisfied with the overall quality of teaching. Preparation for practice was identified as needing improvement, with 26% and 34% of respondents giving an unsatisfactory rating to career guidance and assistance with finding employment, respectively. Although 80% of respondents reported receiving ongoing feedback and 84% discussed their evaluations with their supervisors, only 38% of evaluations were completed by the end of the rotation. The results indicate that residents are generally satisfied with their experiences during residency training, especially with their overall educational experience. Areas of improvement include preparation for practice and timeliness of evaluations. Further iterations of this survey are needed to refine the instrument, identify data trends and maintain quality control in residency training programs. Frank JR (ed.).

Abstract Context Medical students, especially at osteopathic medical schools, have limited research exposure. Systematic instruction in research, supervised by qualified mentors, could motivate osteopathic medical students to pursue research in their careers, thereby increasing the number of future clinician-scientists. Recruiting and retaining suitable research mentors are crucial to sustaining such programs, but this task is also particularly challenging for osteopathic medical schools. Objectives To assess mentors' experiences in a voluntary student-mentor medical research program. Methods An online survey was sent to 76 university- or hospital-based participants who previously mentored 219 medical students between 2014 and 2019. The questionnaire consisted of 13 items with responses in checklist, five-point Likert scale, and categorical multiple-choice formats, assessing motivation for participation, satisfaction with the program, and interest in future participation. Data were analyzed descriptively, and responses from mentors at the university and hospital were compared using univariate logistic and ordinal regression analyses. Results Among 70 (92.1%) mentors who responded to the survey, 61 (87.1%) reported being motivated by a desire to help medical students learn research. Forty-nine (70.0%) mentors indicated that furthering their own research productivity was a motivation, and hospital-based mentors were statistically significantly more likely to endorse this source of motivation (OR=2.02; 95% CI=1.18–3.45; p=0.01). Most respondents were satisfied with the quality of the students' work (59 [84.3%]) and with the program (59 [85.5%]). However, 46 (65.7%) suggested the program could be enhanced by requiring medical students to be physically present in the clinic or laboratory for a minimum amount of time. Importantly, most (58 [84.1%]) mentors reported that they would be interested in participating in future mentored research programs. Conclusions Mentors were motivated to participate in the voluntary research program for both altruistic and professional reasons. Since most mentors reported being satisfied with the program, it is likely they would participate in future mentored research programs. Our results suggest that mentors viewed this voluntary research program as mutually beneficial.

Objectives: The Internet, especially YouTube, is an important and growing source of medical information. The content of this information is poorly evaluated. The objective of this study was to analyze the quality of YouTube video content on meniscus repair. The hypothesis was that this source of information is not relevant for patients. Methods: A YouTube search was carried out using the keywords "meniscus repair". Videos had to have had more than 10,000 views to be included. The videos were analyzed by two evaluators. Various features of the videos were recorded (number of views, date of publication, "likes", "don’t likes", number of comments, source, type of content and the origin of the video). The quality of the video content was analyzed by two validated information system scores: the JAMA benchmark score (0 to 4) and the Modified DISCERN score (0 to 5). A specific meniscus repair score (MRSS scored out of 22) was developed for this study, in the same way that a specific score has been developed for other similar studies (anterior cruciate ligament, spine, etc.). Results: Forty-four (44) videos were included in the study. The average number of views per video was 180,100 (± 222,000) for a total number of views of 7,924,095. The majority of the videos were from North America (90.9%). In most cases, the source (uploader) that published the video was a doctor (59.1%). A manufacturer, an institution and a non-medical source were the other sources. The content actually contained information on meniscus repair in only 50% of the cases. The mean scores for the JAMA benchmark, MD score and MRSS were 1.6/4± 0.75, 1.2/5 ± 1.02 and 4.5/22 (± 4.01) respectively. No correlation was found between the number of views and the quality of the videos. The quality of videos from medical sources was not superior to those from other sources. Conclusion: The content of YouTube videos on meniscus repair is of very low quality. Physicians should inform patients and, more importantly, contribute to the improvement of these contents.

This study aimed to evaluate the general quality of life (QoL) of Brazilian vegetarians. A cross-sectional study was conducted with Brazilian vegetarian adults (18 years old and above). Individuals were recruited to participate in a nationwide online survey that comprised the WHOQOL-BREF as well as sociodemographic and characterization questions related to vegetarianism. The WHOQOL-BREF is composed of 24 items which are divided into four domains (domain 1: physical health; domain 2: psychological well-being; domain 3: social relationships; and domain 4: environment), plus two general items which were analyzed separately, totaling 26 items. The answers from the questionnaire were converted into scores with a 0–100 scale range, with separate analyses for each domain. Results were compared among groups based on the different characteristics of the vegetarian population. A total of 4375 individuals completed the survey. General average score results were 74.67 (domain 1), 66.71 (domain 2), 63.66 (domain 3) and 65.76 (domain 4). Vegans showed better scores when compared to the other vegetarians, except in domain four, where the statistical difference was observed only for semi-vegetarians (lower score). Individuals adopting a vegetarian diet for longer (>1 year) showed better results for domains one and two, with no difference for the other domains. Having close people also adopting a vegetarian diet positively influenced the results for all domains. On the other hand, it was not possible to distinguish any clear influence of the motivation for adopting a vegetarian diet on the scores’ results. Adopting a vegetarian diet does not have detrimental effects on one’s QoL. In fact, the more plant-based the diet, and the longer it was adopted, the better the results were.
