The most demanding passages of play in football competition: a comparison between halves

The purpose of this investigation was to determine the differences between halves in the most demanding passages of play in football players according to playing position and duration-specific activity. Global positioning system data were collected from twenty-three football players from a reserve squad of the Spanish La Liga. A total of 265 individual match half data were analysed across the competitive season. Players were categorised based on positional groups: full-back (FB), central defender (CD), midfielder (MF), offensive midfielder (OMF) and forwards (FW). The most demanding passage of match play was analysed using a rolling average method, where maximal values were calculated for five different time durations (1, 3, 5, 10 min and half completed) using distance (m·min-1), high metabolic load distance (HMLD; m·min-1) and average metabolic power (AMP; W·kg-1) as variables of interest. The differences between the first and second half increased as the rolling duration increased, reaching the greatest difference between halves in the complete half (45 min) in all the variables studied (ES = 0.54 ± 0.15, 0.75 ± 0.15 and 0.76 ± 0.15 in distance, HMLD and AMP). The CDs were the players that presented the greatest differences, and it was in the AMP variable where the greatest differences between the first and second half were found. Large decreases in AMP were found for CD (ES = -1.30 ± 0.36) and moderate decreases were found in AMP for FB (ES = -0.84 ± 0.30) and OMF (ES = -0.78 ± 0.37). These results provide insight into the most demanding passages of play to inform training practices for specific football playing positions.
The Role of Visual Feedback and Creative Exploration for the Improvement of Timing Accuracy in Performing Musical Ornaments

in developing a visual feedback system for a creative activity such as music performance, the objective is not just to reinforce one particular manner of performing. Instead, a desirable characteristic might be that the visual feedback enhances flexibility and originality, in addition to contributing to performance precision. In an experimental study focused on the timing of a musical ornament, we examined whether the instruction to explore ornament timing in training trials with or without visual feedback leads to improved temporal precision in imitating target performances of the ornament, and whether visual feedback enhances the performance diversity during training. The study uncovered distinct strategies of exploration of the performance of the musical ornament and highlighted the dynamics of exploration behavior during training. Visual feedback enhanced exploration of temporal characteristics and influenced imitation accuracy. This study opens up educational possibilities for the training of performance skills and provides direction for further investigation of creative processes in performance.
Care seeking behaviour of Bangladeshi migrant workers in Sarawak, Malaysia

Background: Migrant workers are exposed to vulnerable health risks related to occupational safety, infection and personal health risk behaviours. These vulnerabilities, together with low capacity to pay medical care, and poor access to healthcare, can result in unsatisfactory health outcomes. This objective of the study was to determine the pattern of morbidity and the care seeking behaviour of Bangladeshi migrant workers in Sarawak. Methods: This cross-sectional study was conducted among Bangladeshi migrant workers in selected districts in Sarawak, Malaysia. A total of 314 Bangladeshi workers were interviewed by face to face using a pre-designed and validated questionnaire. Simple descriptive analysis was done using SPSS version 22.0. However, to supplement the quantitative findings, field notes were also analysed. Results: The mean (SD) age of the respondents was 35.9 (7.3) years. Most of the workers were engaged in manufacturing job (43%) followed by construction (32.2%) and a variety of job according to the employers' desire (22.9%). The median monthly salary of the workers was MYR 923 with median duration works was 10 years. One-fourth of the workers (25.5%) had no health insurance, while another one tenth of workers were unaware of health insurance. It was found that 20% had medial ailments in the last two weeks, while 45.2% had physical complaints in the last one month. The most frequent complaints were fever (48.4%) followed by injuries (11.3%) in the last two weeks. About three fifths (57.4% in last two weeks and 60.6% in last one month) visited private health hospitals or clinics for their treatment. Only a few workers visited public hospitals or clinics for their ailments. One-fifth of the workers were self-medicated. While another one tenth of workers visited traditional healer for their ailments. Qualitative analysis revealed a high cost and no scope of bargain as factors which discourage them to take treatment from public hospitals or clinics. The majority of migrant workers in this study sought healthcare when they fell ill. Conclusion: However, knowledge about health-related insurance was poor and low wage might be significant issues in accessing health care services. The study concluded that workers’ friendly health policy could be instituted for the welfare of the foreign workers’ despite of their awareness of local health services.

On creating a student model to assess effective exploratory behaviour in an open learning environment

O p e n learning environments give users a h igh degree of freedom and control to explore. T h i s freedom and cont ro l is beneficial for some students, resul t ing i n a deeper understanding of the mater ia l than they would gain through t rad i t iona l means of ins t ruc t ion . For others, this type of environment is problemat ic , since for various reasons, these students are not able to explore effectively. One way to address this problem is to augment the environments w i t h ta i lored support . T o provide feedback ta i lored to the student 's difficulties, the environment must have some way of moni to r ing and assessing her explora t ion. T h i s thesis investigates the creat ion of a student model that assesses the effectiveness of the student 's exploratory behaviour . M o n i t o r i n g user behaviour i n an open learning environment is difficult since there is typ ica l ly l i t t le informat ion available to the model to make its assessment. T h e model can view w i t h which items the student experiments, but does not have direct access to the effects of those experiments on her understanding of the domain . A s a result, how to mode l effective exploratory behaviour has not been extensively researched. T h e Student M o d e l in this thesis has been implemented and evaluated in the context of the A d a p t i v e C o a c h for E x p l o r a t i o n ( A C E ) . T h e model monitors the student's explora t ion of A C E ' s activit ies to generate an assessment of how effectively the learner is explor ing . Us ing this assessment, A C E ' s Coach provides ta i lored feedback to guide the student's explora t ion process. To handle the large amount of uncer ta inty present in the model l ing task, the Student M o d e l is based on Bayesian Networks . T h e features of A C E ' s Student M o d e l have been developed and refined using two evaluations of A C E w i t h human subjects. T h e first evaluat ion was used to evaluate the effects of inc lud ing tai lored support in an open learning environment, and also provided insight into ways to improve the Student M o d e l ' s p re l iminary design. T h e second evaluat ion tested those improvements. Resul ts of the evaluations found that both the frequency w i t h which students accessed the ta i lored feedback and the number of activit ies that they explored effectively (as determined by the Student M o d e l ) were posi t ively correlated w i t h learning.
Aortic dissection after ramucirumab infusion

A female patient in her seventies affected by a signet-ring cell carcinoma G3pT4N3 (24/29), with lymphovascular invasion, HER2-negative. After completing three cycles of first-line systemic treatment in combination with cisplatin (CDDP) + 5-fluorouracil (5FU), a new systemic therapy line with paclitaxel + Cyramza (ramucirumab) was planned. On the day after the first administration the patient manifested a Standford type A aortic dissection (AD), with a diameter of around 6.5 cm and dissection flap originating in the ascending aorta below the brachiocephalic trunk, extended to the whole descending aorta until the carrefour. The causal relationship between adverse drug reactions and Cyramza, calculated using the Naranjo algorithm, led to a result of 'probable' correlation between ramucirumab and AD. The endothelial dysfunction associated with vascular endothelial growth factor pathway inhibitors (VPIs) would seem to be the most plausible explanation for such events: it causes thromboembolic events and cardiovascular complications.
Fault detection and accommodation in nonlinear time-delay systems

Fault detection, estimation and compensation problem for a class of disturbance given time delay nonlinear systems is addressed. The proposed approach relies on an iterative learning observer (ILO) for fault detection and estimation. Under no faults, the ILO supplies accurate disturbance estimation where the effect of disturbances on estimation error dynamics can be accordingly attenuated. The proposed ILO can detect sudden changes in the nonlinear system. Thus the ILO is used to excite an adaptive control law in order to offset the effect of faults on the system dynamics. In addition, the ILO-based adaptive fault compensation strategy can handle multiple faults. The fault detection and compensation strategy is demonstrated in simulation on an automotive engine problem.
Intensified neoadjuvant radio-chemotherapy for locally advanced rectal cancer: mono-istitutional experience and long-term results

Background: Purpose: The purpose of our study is to demonstrate that intensified neoadjuvant chemo-radiotherapy (CRT) treatment in locally advanced rectal cancer (LARC), aimed at further enhancing the complete pathological response and local disease control, is feasible and well tolerated. Materials and Methods: From January 2011 to December 2015, 62 patients (women 21, men 41, mean age 61,5, range 36-84) with LARC (cT2-3 cN0-2) were enrolled in our institution. All patients performed an intensified neo-adjuvant CRT treatment according to the following scheme: FOLFOX4 induction chemotherapy for 3 cycles, followed by a concomitant radio-chemotherapy, with concomitant boost pelvic radiotherapy to a total dose to the primary of 54 Gy and daily continuous infusion of 5-Fluorouracil. After 6-8 weeks pts were re-evaluated by means of colonoscopy, body TC and pelvic MRI. Results: Intensified CRT compliance was 90%. Grade I-II proctitis according to CTCAE v4.0 was 43%, grade III diarrhea was 10%, grade I-II genito-urinary toxicity was 29%. Eleven patients (19%) had a complete pathological response (pCR), 37 patients had a partial response. Sixty patients received surgery, two refused it: sphinctersaving procedure was performed in 85% of patients, Miles’ surgery in 15% of them. Fifty-nine patients are alive, after a median follow-up time of 43 months. Six patients experienced a distant metastatic disease, and two patients a local relapse. Conclusion: This study has shown that the intensification of preoperative systemic therapy, together with intensification of radiotherapy, was feasible, well tolerated and has obtained high rates of local disease control (96,5%), with 19% of pCR rate.
Effects of Royal Jelly Administration on Lipid Profile, Satiety, Inflammation, and Antioxidant Capacity in Asymptomatic Overweight Adults

Objectives Obesity and overweight are chronic disorders of multifactorial origin that are characterized by high oxidative status and by chronic activation of macrophages in peripheral tissues. Effective therapeutic approaches to lower inflammation and oxidative stress are currently of general interest. Royal jelly (RJ) is a functional food with a broad range of pharmacological activities, mainly used by healthy individuals or borderline patients to protect themselves against disease onset. The objective of this randomized, double-blind, placebo-controlled trial was to investigate the effects of RJ supplementation on metabolic profile and oxidative and inflammatory parameters in asymptomatic overweight adults, considered at an early stage of developing metabolic syndrome. Material and Methods The experimental group (n=30) was given RJ and the control group (n=30) was provided with a placebo for eight weeks. Anthropometric, biochemical parameters, biomarkers of oxidative stress, and inflammation were assessed at baseline, after 4 and 8 weeks of the intervention, and after additional 2 weeks of follow up. Results and Conclusion Compared with the placebo, RJ supplementation demonstrated a statistically significant decrease in total cholesterol (6.7%; p=0.041) and inflammatory marker C-reactive protein (19%; p=0.027), whereas significant increases were observed in anti-inflammatory marker adiponectin (34%; p=0.011), endogenous antioxidants bilirubin (35%; p=0.002) and uric acid (5%; p=0.018), total antioxidant capacity in serum (54%; p=0.005), and leptin (17%; p=0.025). The present study demonstrated positive effects of RJ administration on lipid profile, satiety, inflammation, and antioxidant capacity in overweight adults. Therefore, our study supports the benefits of RJ supplementation for the improvement of human health.
Flight validation of a metrics driven L1 adaptive control in the presence of general unmodeled dynamics

The paper summarizes the results of an ongoing effort in the development and flight validation and verification of the metrics driven L1 adaptive flight control system. In particular, the paper develops a unified framework for design, implementation, validation and verification of flight critical control systems including: (i) definition of experimental control validation technique that accounts for generalized plant uncertainties or unmodeled dynamics; (ii) tuning the developed L1 adaptive controller to explicitly address performance metrics in the presence of modeling uncertainties under adverse flight conditions; (iii) development of a flight control system testing environment for implementation of the resulting algorithms onboard of a small unmanned aerial vehicle; and (iv) designing and conducting of a comprehensive flight test validation and verification program that demonstrates performance of the proposed adaptive control algorithm.
Optimal Control of Wireless Networks with Finite

This paper considers network control for wireless networks with finite buffers. We investigate the performance of joint flow control, routing, and scheduling algorithms which achieve high network utility and deterministically bounded back- logs inside the network. Our algorithms guarantee that buffers inside the network never overflow. We study the tradeoff between buffer size and network utility and show that if internal buffers have size (N − 1)/� then a high fraction of the maximum utility can be achieved, wherecaptures the loss in utility and N is the number of network nodes. The underlying scheduling/routing component of the considered control algorithms requires ingress queue length information (IQI) at all network nodes. However, we show that these algorithms can achieve the same utility performance with delayed ingress queue length information. Numerical results reveal that the considered algorithms achieve nearly optimal network utility with a significant reduction in queue backlog compared to the existing algorithm in the litera- ture. Finally, we discuss extension of the algorithms to wireless networks with time-varying links.
Perceptions of household measuring utensils amongst Mmopane community in Botswana

In assessing adults’ dietary intakes, nutritionists and dietitians often rely on clients’ reported food consumption, estimated in units of households measuring utensils (cups, tablespoons and teaspoons). However, it is yet to be established whether the public can accurately estimate the capacity of household utensils and the amount of food consumed in units of household measuring utensils. The purpose of the study was to examine conceptions of household measuring utensils and establish how well participants estimate the sizes of household measuring utensils comparing with metric sizes of 250 ml for a cup, 15 ml and 5 ml for a tablespoon and a teaspoon, respectively. The study used a cross-sectional survey design with a random sample of 253 participants aged between 18-60 years. Participants were asked to complete questionnaires by identifying a sample that best approximated their perception of a standard (metric) cup, tablespoon and teaspoon. The results revealed that most adults’ perceptions of the utensils differed from the correct measurements (metric sizes) of household utensils. Fifty eight percent of participants identified a sample of 375 ml sample as the one that they thought best approximated a standard / metric cup while 19% identified a 330 ml sample as the one that best approximated a metric cup. Only 13% of participants correctly identified a standard cup. Pertaining to tablespoon and teaspoon sizes, only about 7% and 38% participants correctly identified a tablespoon and teaspoon, respectively. The weighted mean size of a cup as perceived by participants was estimated at 332 ml. The mean difference between what participant perceived best explained their understanding of a cup (332ml) from the metric size of 250 ml was statistically significant (significant one sample t-test; T = 20. 234, p< .001; df = 252). Similarly, the average size of a teaspoon as perceived by participants differed from standard/ metric size of a teaspoon ( T = -4. 326, p< .001; n= 251 ). Similarly, observations were made with regard to the difference between perceived size of tablespoon ( T = -51.20, p< .001; n = 252 ) and metric size of a tablespoon. Lastly, participants’ perception of sizes of household utensils was influenced by age, education and gender. The findings underscore the importance of establishing local notions of household measures before assessment methods that rely on their use are administered. Further, the findings suggest the need for clients’ education on household measures prior to use of the same in dietary assessments.
Prevalence of vitamin D deficiency in Iraqi female at reproductive age

Background: Vitamin D, a fat-soluble vitamin that now is recognized as a prohormone that recently has an important role in the reproductive health. Vitamin D deficiency (VDD) had high prevalence worldwide and was estimated to affect about 50% of the population worldwide. Hypovitaminosis D related to several health problems in women such as infertility, polycystic ovarian syndrome endometriosis, and pregnancy-related complications such as preeclampsia and caesarian section. Objective: The aim of the study is to evaluate the serum level of Vitamin D in sample of Al-Hilla women at reproductive age. Materials and Methods: The total number included in the study was 500 patients. They were companions of patients visiting specialist gynecologic and obstetric private clinics in Hilla City from first of October 2017 to end of March 2018 the patients were grouped into three groups according to their age: Group 1: Patients aged (15–30) years. Group 2: Patients aged 31–40 years. Group 3: Patients aged more than 40 years and premenopausal. The data were collected which were then analyzed statistically and registered. Results: Whole sample mean serum Vitamin D level 15.85 ± 7.69 and the percentage of deficiency over all the sample was 76%. Regarding the result in each group, Group 1 include 350 patients, mean age (23.8 ± 3.96), and mean serum Vitamin D level (16.16 ± 7.69), t-test was statistically significant P < 0.05. Group 2 include 119 patients, mean age (35.2 ± 2.9), and mean serum Vitamin D level (15.14 ± 7.42), t-test was statistically significant P < 0.05. Group 3 include 31 patients, mean age (42.81 ± 1.45), and mean serum Vitamin D level (14.82 ± 7.77), t-test was statistically significant P < 0.05. Conclusion: Results of our study revealed a widespread, severe VDD in women at reproductive age with aproportion of deficiency in the whole sample of 76% and proportion of insufficiency 18% while only 7% had sufficient Vitamin D Serum level.
Evaluation of Sleep Patterns and Self-Reported Academic Performance among Medical Students at the University of Ghana School of Medicine and Dentistry

Background Sleep habits and problems play a vital role in determining sleep quality. We describe sleep habits and problems among medical students and assess their possible effect on self-reported academic performance. Methods We conducted a cross-sectional study among medical students at the University of Ghana during the 2014/2015 academic year. Data was collected using the Pittsburgh Sleep Quality Index (PSQI), a self-report questionnaire that assesses sleep quality over a 1-month time interval. Results 153 medical students were recruited comprising 83 (54.2%) females and 70 (45.8%) males with a mean age of 23.1 ± 2.4 years. The mean duration of night sleep was 5.7 ± 1.2 hours; 88 (57.5%) students had sleep latency of 10-30 minutes while 18 (11.8%) woke up nightly. 23 (15%) students experienced nightmares, 13 (8.5%) snored at night, and only one student reported coffee intake of 2-3 times daily. Sleep quality was poor in 86 (56.2%) and was significantly associated with sleep latency, morning tiredness, daytime sleepiness during lectures, academic performance, living conditions, leisure time, frequency of nocturnal awakenings, waking up due to noise, sleep walking, and nocturnal awakening to use washroom. There was also a significant positive relation between sleep quality and academic performance (X2 = 10.004 p = 0.019). Conclusion Poor sleep quality and daytime dysfunction are widespread among medical students in Ghana. There was a significant positive relation between sleep quality and self-reported academic performance.
