The Impact

Studies on the driver's fatigue, must focus on at least two things: the time-of-day that affect by circadian factors, and time-on-task. This paper discusses the risk level of driver fatigue, which generally have to drive in a long duration or more than 4 hours. The risk of fatigue was assessed using Fatigue Likelihood Scoring (FLS) by Transport Canada. Based on interviews with 24 inter-city bus drivers, 18 of the 24 drivers have a very high risk of fatigue that characterized by FLS scores greater than 20, while the rest have a high risk driver that characterized by FLS value greater than 10. A high risk of chronic fatigue that experienced by most of drivers caused by working hours which is more than 36 hours in a week, the duration of the shift of greater than 8 hours a day, lack of time off, the amount hours of driving at night, and the amount of time off.

The Impact

An auditor generating potential explanations for an unusual variance in analytical review may utilize a decision aid, which provides many explanations. However, circumstances of budgetary constraints and limited cognitive load deter an auditor from using a lengthy list of explanations in an information search. A two-way between-subjects design was created to investigate the effects of two complementary approaches to trimming down the lengthy list on the number of remaining explanations carried forward into an information search. These two approaches, which represent the same goal (reducing the list) but framed differently, are found to result in a significantly different number of remaining explanations, in both low- and high-risk audit environments. The results of the study suggest that the extent to which an auditor narrows the lengthy list of explanations is important to the implementation of decision aids in analytical review.

The outbreak of COVID-19 in China has attracted wide attention from all over the world. The impact of COVID-19 has been significant, raising concerns regarding public health risks in China and worldwide. Migration may be the primary reason for the long-distance transmission of the disease. In this study, the following analyses were performed. (1) Using the data from the China migrant population survey in 2017 (Sample size = 432,907), a matrix of the residence–birthplace (R-B matrix) of migrant populations is constructed. The matrix was used to analyze the confirmed cases of COVID-19 at Prefecture-level Cities from February 1–15, 2020 after the outbreak in Wuhan, by calculating the probability of influx or outflow migration. We obtain a satisfactory regression analysis result (R2 = 0.826–0.887, N = 330). (2) We use this R-B matrix to simulate an outbreak scenario in 22 immigrant cities in China, and propose risk prevention measures after the outbreak. If similar scenarios occur in the cities of Wenzhou, Guangzhou, Dongguan, or Shenzhen, the disease transmission will be wider. (3) We also use a matrix to determine that cities in Henan province, Anhui province, and Municipalities (such as Beijing, Shanghai, Guangzhou, Shenzhen, Chongqing) in China will have a high risk level of disease carriers after a similar emerging epidemic outbreak scenario due to a high influx or outflow of migrant populations.

The Impact

Along with the amount of time spent learning (or time-on-task), the quality of learning time has a real influence on learning performance. Quality of time in online learning depends on students’ time availability and their willingness to devote quality cognitive time to learning activities. However, the quantity and quality of the time spent by adult e-learners on learning activities can be reduced by professional, family, and social commitments. Considering that the main time pattern followed by most adult e-learners is a professional one, it may be beneficial for online education programs to offer a certain degree of flexibility in instructional time that might allow adult learners to adjust their learning times to their professional constraints. However, using the time left over once professional and family requirements have been fulfilled could lead to a reduction in quality time for learning. This paper starts by introducing the concept of quality of learning time from an online student-centred perspective. The impact of students’ time-related variables (working hours, time-on-task engagement, time flexibility, time of day, day of week) is then analyzed according to individual and collaborative grades achieved during an online master’s degree program. The data show that both students’ time flexibility (<em>r</em> = .98) and especially their availability to learn in the morning are related to better grades in individual (<em>r</em> = .93) and collaborative activities (<em>r</em> = .46).

Emergency Anaesthesia

Background: One important task of the emergency anaesthesia service is to provide rapid, safe and effective anaesthesia for emergency caesarean sections (ECS). A Decision to Delivery Interval (DDI) <30 minutes for ECS is a quality indicator for this service. The aim of this study was to assess the DDI and the impact of chosen anaesthetic technique (general anaesthesia (GA), spinal anaesthesia (SPA) with opioid supplementation, or “top-up” of labour epidural analgesia (tEDA) with local anaesthesia and fentanyl mixture) and work shift for ECS at Danderyds Hospital, Sweden. Methods: A retrospective chart review of ECS at Danderyds Hospital was performed between January and October 2016. Time between decision for CS, start of anaesthesia, time for incision and delivery, type of anaesthetic technique, and time of day, working hours or on call and day of week, Monday – Friday, and weekend was compiled and analysed. Time events are presented as mean ± standard deviation. Non-parametric tests were used. Results: In total, 135 ECS were analysed: 92% of the cases were delivered within 30 minutes and mean DDI for all cases was 17.3±8.1 minutes. GA shortened the DDI by 10 and 13 minutes compared to SPA and tEDA (p<0.0005). DDI for SPA and tEDA did not differ. There was no difference in DDI regarding time of day or weekday. Apgar <7 at 5’ was more commonly seen in ECS having GA (11 out of 64) compared to SPA (2/30) and tEDA (1/41) (p<0.05). Conclusion: GA shortens the DDI for ECS, but the use of SPA as well as tEDA with opioid supplementation maintains a short DDI and should be considered when time allows. Top-up epidural did not prolong the DDI compared to SPA. The day of week or time of ECS had no influence on the anaesthesia service as measured by the DDI.

Objective: To assess the impact on mental health of health professionals during the COVID-19 pandemic. Methods: Narrative review of the literature, of a descriptive character, carried out through bibliographic survey through a search strategy based on the terms: Mental health, Health professionals and Covid-19. Inclusion criteria were adopted: articles published in Portuguese, English and Spanish indexed in the PUBMED / MEDLINE, SciELO and VHL databases published between February 2020 and August 2020. Results: The COVID-19 pandemic established a chaos in all sectors of society, the health sphere was the most affected. The routine of health professionals was abruptly altered by the constant confrontation of an enormous pressure that goes from working in an environment with a high risk of contamination without adequate protection, excessive working hours, frustration, lack of contact with family to experiences of discrimination by a small part of society who see them as potential vectors of disease transmission. Conclusion: The pandemic was extremely harmful to the health of health professionals, affecting their emotional balance. It was shown that the pandemic scenario caused a lot of damage, as these professionals were exposed to high and intense workloads, which caused physical and mental exhaustion, leading to a feeling of weakness and professional insecurity.

Abstract Objective: The present study was conducted to investigate the impact of breastfeeding on the risk of development of acute leukemia among children Admitted to Alexandria University Children's Hospital. METHODS: A case control study included 134 ALL&AML cases & 134 matched controls for age & sex from the same family relatives to evaluate socioeconomic & genetic causes of the disease. The mothers were interviewed for the completion of interview format that included: duration & patterns of breastfeeding. RESULTS: lower proportion of acute leukemia cases 59.7% were exclusively breast-fed babies as compared to 89.6% of the control subjects. However, higher proportions of index children were either predominant breast-fed 19.4% or complementary-fed 10.4%. Nearly 10.4% were bottle-fed babies as compared to none of their controls. The differences between cases & controls as regards pattern of breast feeding were statistically significant where p<0.001. As regards duration of breastfeeding 75.4% of index children were breast-fed for more than 6 months as compared to vast majority of their controls (97.8%). The difference between cases & controls was statistically significant where p <0.001. The association also was statistically significant when 2 groups (standard & high risk) were considered as regards pattern of breastfeeding where x2=13.055, p =0.004. The multivariate logistic regression analysis indicated that bottle feeding had the odds of 7.76 of being at high risk level for acute leukemia (OR=7.76, 95% CI 1.9-33.8). CONCLUSION: Exclusive breast-feeding and breast-feeding for one year are protective against acute childhood leukemia. Table 1.

Abstract ‘Free of haste, careless of exactitude, unconcerned by productivity.’ This is how Jacques Le Goff characterized the temporality of pre-industrial rural working life. In E. P. Thompson’s famous argument, it was only with the arrival of the factory and the industrial age that the erratic rhythms of English working people were abruptly swept away by a new imperative for long and regular working hours controlled by the clock. It is a thesis that has been much debated in relation to pre- and non-industrial cities, and with regard to the impact of industrialization when it arrived. There has, however, been very little scrutiny of its account of the relationship between time and work in rural England before industrialization. This article therefore offers the first extensive empirical study of both time consciousness and work-related time-use in sixteenth- and seventeenth-century rural England. It does so by drawing on the testimony that ordinary women and men gave before the courts, testimony that often divulged both how those people told the time of day, and how they used it. What emerges is that English rural society in this period had a relatively high degree of clock-time awareness, and that everyday patterns of work followed more consistent and regular rhythms than Thompson’s thesis allows. As a consequence, the article argues that we need to question the assumption that the long hours and work discipline of ‘modernity’ had no roots in ‘traditional’ English rural life.

To the article the results of the theoretical and experimental researches are given on questions of estimates of the dynamic rate effect of raindrop impact on soil. The aim of this work was to analyze the current methods to determine the rate of artificial rain pressure on the soil for the assessment of splash erosion. There are the developed author’s method for calculation the pressure of artificial rain on the soil and the assessment of splash erosion. The study aims to the justification of evaluation methods and the obtaining of quantitative characteristics, prevention and elimination of accelerated (anthropogenic) erosion, the creation and the realization of the required erosion control measures. The paper considers the question of determining the pressure of artificial rain on the soil. At the moment of raindrops impact, there is the tension in the soil, which is called vertical effective pressure. It is noted that the impact of rain drops in the soil there are stresses called vertical effective pressure. The equation for calculation of vertical effective pressure is proposed in this study using the known spectrum of raindrops. Effective pressure was 1.4 Pa for the artificial rain by sprinkler machine «Fregat» and 5.9 Pa for long distance sprinkler DD-30. The article deals with a block diagram of the sequence for determining the effective pressure of rain drops on the soil. This diagram was created by the author’s method of calculation of the effective pressure of rain drops on the soil. The need for an integrated approach to the description of the artificial rain impact on the soil is noted. Various parameters characterizing drop erosion are considered. There are data about the mass of splashed soil in the irrigation of various irrigation machinery and installations. For example, the rate (mass) of splashed soil was 0.28…0.78 t/ha under irrigation sprinkler apparatus RACO 4260–55/701C in the conditions of the Ryazan region. The method allows examining the environmental impact of sprinkler techniques for analyzes of the pressure, caused by raindrops, on the soil. It can also be useful in determining the irrigation rate before the runoff for different types of sprinkler equipment and soil conditions.
