Optimalizace generelu cyklistických tras ve městě Brně / Optimization of the general plan cycling routes in Brno

Stupavská, Jaroslava January 2019 (has links)
At present, cycling is at the forefront of smaller and larger cities. It is important to put emphasis on its development and the support of the infrastructure, in building new and existing cycling routes as well. An increasing number of cyclists on the roads causes a number of traffic accidents, especially with devices of transport. That is why to aim to increase the safety of cyclists themselves but also other road users. In my diploma thesis, I do evaluate the existing state of critical places on cycling routes and try to optimally solve the problems I have identified. It is mainly the connection of cycling infrastructure, for more comfortable ride, and increased safety of cyclists in Brno. The source I worked with was a bicycle transport manual of the Brno city.

Safety education in California elementary schools

Cunninghame, Maxwell Alexander 01 January 1954 (has links)
Statement of the problem: How does the program of safety education in California elementary schools meet the needs of youth as defined by selected authoritative criteria? A sampling of 112 elementary schools of various grade combinations in thirty-four California counties furnished the basis for a questionnaire study. These schools fell within the average daily attendance range of 165 to 599. In addition to this the questionnaire was sent to twelve large city schools in various parts of the state, but in no case did the attendance figure go over seven hundred. The majority of the schools were in rural or semi-rural areas.

Optimization of Physical Properties of Hydraulic Cushion Cells for Vehicle Impact Restraint

Hughes, William Evans 01 August 1969 (has links)
In recent years, the United States has witnessed a vast expansion of its internal highway system. Concurrently the number of vehicles has increased as has the average yearly milage per vehicle. Unfortunately, along with increased vehicle use there has been an alarming increase in annual loss of life and property due to traffic accidents. Statistics verify that the modem freeway systems greatly reduce dangerous head on collisions but the rate of accidents due to collisions with fixed objects in or near the roadway has increased almost 50 percent in the past thirty years.^1 In 1966, about 13>300 deaths were attributed to such fixed 2 object collisions.^2 This is over 20 percent of the total traffic death toll that year.

Patient waiting times within public Emergency Centres in the Western Cape: describing key performance indicators with respect to waiting times within Western Cape Emergency Centres in 2013-2014

Cohen, Kirsten Lesley January 2017 (has links)
Background: Much emphasis has been placed on Quality Measurements or Key Performance Indicators in Emergency Medicine. Internationally, KPI's are used to measure and improve quality of care, with a major emphasis on waiting times, measured as time-based KPI's. These times are related to the various stages of a patient journey through the Emergency Center. In South Africa this has not been routinely done. The Western Cape has conducted audits in recent years to measure these. This study aims to provide a snapshot of waiting times (specifically time to triage, time to doctor, time to disposition decision and time to departure from the EC) within Cape Town public sector Emergency Centres. Methods: This is a retrospective descriptive study of waiting times for all patients presenting to Emergency Centres in the Western Cape in 2013-2014, as per six monthly waiting times audits conducted by the Western Cape Department of Health. A wide variety of emergency centers were audited, from 24 hour clinics to larger acute hospital based ECs. Results: The proportional acuity difference between hospitals and CHC for the first random 100 folders were statistically no different. Arrival to triage times were universally longer than internationally accepted as safe. The mean time for all-comers across all facilities was just under an hour, the higher acuity patients were triaged significantly faster (half an hour) than the lower acuity patients (hour or more). This difference was significant for hospitals, with a non-significant trend for CHCs. At hospital ECs, green patients were triaged significantly faster than yellow patients; this was not the case at CHCs. The mean time from triage to clinician consultation for all-comers across all facilities (over two hours) was significantly longer at hospitals as compared to clinics. Time from triage to clinician consultation, per triage category, were longer than the SATS guide times, although higher acuity cases were seen faster than lower acuity cases in a stepwise fashion. Red patients waited nearly an hour on average, with no significant difference between hospitals and CHCs. Orange patients had to wait one to two hours; this was significantly longer at hospitals. The mean time from assessment and management to a disposal decision for all-comers was significantly longer at hospitals as compared to CHCs across all priorities. Green patients took a lot longer at hospital compared to CHCs. A similar pattern was seen for the disposition decision to leaving time. The mean total time was significantly longer at hospitals as compared to clinics. Orange and yellow cases stayed significantly longer at hospitals as compared to CHCs; red and green cases also stayed longer at hospitals as compared to CHCs, though this was not significant. Red cases appeared to stay the longest at CHCs. Conclusions: Patients attending CHCs and hospitals are of similar illness acuity, despite policies dictating that sicker patients should be seen at hospitals not CHC level. CHCs have limited packages of care (decision making investigations, management options and expertise), and can only manage patients to a defined level. Thus, it takes longer for patients who are moderately or very ill to be seen and sorted in a CHC than a hospital, as at a CHC they are generally referred onwards to a hospital. Their journey through the EC will then begin again, so that for sicker patients the time spent in ECs in this study is underestimated. Models need to be explored so that patients receive care at point of contact as far as possible. Since CHC-based ECs see as many patients who are as ill as those in hospitals, these should have similar resources to hospitals, so that only those requiring definite admission need to be referred onwards. Point of care testing, bedside ultrasound, appropriate medications and EM skills should all be available at facilities closest to the patients with emergency conditions. Green patients, the lowest acuity, also take longer to be seen and sorted at hospitals versus CHCs, because investigations are available that are then done as an emergency versus outpatient basis. Efficient and timely outpatient appointments would help mitigate this.

Needs Assessment for Promoting Livestock and Equine Safety for Diné Youth

Shumway, Karah L 01 May 2013 (has links)
The purpose of the research was a formative assessment of Diné (Navajo) parents and community leaders' needs for a training program for the prevention of livestock injuries including those that are horse-related. The research objectives were to identify parents' perceived livestock and horse related injury risks to Diné children and describe Diné community stake holder input on prevention interventions for reducing injury risks to children associated with livestock and horse-related activities on the farm or ranch. The assessment utilized a survey constructed of closed and open-ended questions to gauge Diné farmers' and ranchers' perceptions of injury risks to children who live or work on an agricultural operation. Additional questions were asked to gauge Diné acceptance of an online training program as a prevention intervention to reduce livestock and horse-related injuries to children. A total of 96 individuals agreed to participate in the survey and provided usable responses. A total of 53% of participants were female. There were 58 individuals who perceived that a youth who worked with intact male livestock was at a high risk for injury. A total of 25 individuals perceived that a youth who rides a horse without an equestrian riding helmet was at a high risk for injury. There were 48 individuals who strongly agreed that they would utilize an interactive internet resource to promote agricultural safety for Diné youth. There were 22 individuals who strongly agreed that they would utilize internet social networks to promote agricultural safety and health for Diné youth. This project may serve as a model of collaboration to help researchers address the agricultural safety needs of other vulnerable populations. When participants were asked if there were safety issues associated with having youth working on the farm or ranch, a very large portion felt that the biggest issue was a lack of education and instruction from their elders.

Impact of Leadership Strategies on Perceived Climate of Safety at the Construction Job Site

Estrin, Joshua M. 01 January 2017 (has links)
Despite the creation of the Occupational Safety and Health Administration (OSHA) more than 30 years ago, the construction industry is in conflict with itself. It is locked in a struggle to effectively keep its workforce protected from unsafe acts, unsafe conditions, or a combination of both. According to the Bureau of Labor Statistics (BLS), nearly 6.5 million people work at approximately 252,000 construction sites across the United States every day, with the fatal injury rate for the construction industry higher than the national average when compared to all industries. There have been many studies documenting these conditions, but no study has examined leadership styles and their impact on the climate of safety. This study examined the relationship between management’s leadership style and the perception of a climate of safety; the relationship between workers’ perception of leadership style and the perception of a climate of safety; and the relationship between the size of the workforce, the manager’s leadership style, and the perception regarding the climate of safety. The outcomes contribute to the field of conflict resolution as they offer the ability to move from incongruities regarding perceived worker safety to discussions and solutions that are aimed at influencing those policies and procedures at the organizational level that will ensure that a construction worker can perform his or her job free from dangerous work conditions.

Autonomous 3D mapping and surveillance of mines with MAVs

Edwards, Stuart Robert January 2017 (has links)
A dissertation Submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, for the degree of Master of Science. 12 July 2017. / The mapping of mines, both operational and abandoned, is a long, di cult and occasionally dangerous task especially in the latter case. Recent developments in active and passive consumer grade sensors, as well as quadcopter drones present the opportunity to automate these challenging tasks providing cost and safety bene ts. The goal of this research is to develop an autonomous vision-based mapping system that employs quadrotor drones to explore and map sections of mine tunnels. The system is equipped with inexpensive, structured light, depth cameras in place of traditional laser scanners, making the quadrotor setup more viable to produce in bulk. A modi ed version of Microsoft's Kinect Fusion algorithm is used to construct 3D point clouds in real-time as the agents traverse the scene. Finally, the generated and merged point clouds from the system are compared with those produced by current Lidar scanners. / LG2018

Influence of Market Setting and Time of Purchase on Counts of Aerobic Bacteria, Escherichia Coli, and Coliform and Prevalence of Salmonella and Listeria in Beef, Pork, and Chicken in Vietnam

McCain, April Kathleen 11 December 2015 (has links)
The objective of this study was to determine the influence of market type and sampling time on Salmonella and Listeria prevalence and microbiological quality of 540 beef, pork, and whole chicken samples collected in 6 supermarkets (SM), 6 indoor markets (IM), and 6 open markets (OM) at opening (T0) and 4 h after the opening (T4) in Vietnam. Salmonella and Listeria prevalence ranged from 30.4 to 71.0% and 56.6 to 99.9 %, respectively, in beef, pork, and chicken in Vietnam. Aerobic bacteria counts ranged from 10.5 to 11.6 log CFU/g, whereas, E. coli and coliform counts ranged from 7.2 to 11.4 log CFU/g in beef, pork, and chicken in Vietnam. E. coli counts were influenced by the interaction of market type and sampling time in beef and pork. Market characteristic data that were considered relevant to microbiological safety of fresh meat and poultry products were collected for individual samples.

Assessing Patient Safety Culture In United States' Hospitals

Azyabi, Abdulmajeed 01 January 2022 (has links) (PDF)
Patient safety is founded on continuous learning because there is an urgent need to report and learn from errors, accidents, near misses, and adverse events. The traditional approach to patient safety, based on forming mortality committees and investigating accidents, will no longer be effective. Frameworks, surveys, and assessment tools have been developed over the last decade to assist organizations in measuring and understanding their culture. This a retrospective cross-sectional study included 67,010 respondents from Agency for Health care Research and Quality (AHRQ) 2018 comparative database was analyzed using partial least squares structural equation modeling (PLS-SEM). This research explored whether the dominant patient safety culture would impact the frequency of reported events and overall perceptions of patient safety. Furthermore, the study amid to examine whether respondents and hospital characteristics influence the perception of patient safety culture and the impact on healthcare staff. The results in this study showed that the perception of PSC positively influenced the overall perception of patient safety and frequency of event reporting. Moreover, the results revealed that hospital and respondents' characteristics (Staff Position, Teaching Status and Geographic Region) had varying influence on patient safety culture, overall perception of patient safety and frequency of event reporting.
