Human Activity and Motion Pattern Recognition within Indoor Environment Using Convolutional Neural Networks Clustering and Naive Bayes Classification Algorithms

Human Activity Recognition (HAR) systems are designed to read sensor data and analyse it to classify any detected movement and respond accordingly. However, there is a need for more responsive and near real-time systems to distinguish between false and true alarms. To accurately determine alarm triggers, the motion pattern of legitimate users need to be stored over a certain period and used to train the system to recognise features associated with their movements. This training process is followed by a testing cycle that uses actual data of different patterns of activity that are either similar or different to the training data set. This paper evaluates the use of a combined Convolutional Neural Network (CNN) and Naive Bayes for accuracy and robustness to correctly identify true alarm triggers in the form of a buzzer sound for example. It shows that pattern recognition can be achieved using either of the two approaches, even when a partial motion pattern is derived as a subset out of a full-motion path

Factors Influencing Adoption of HR Analytics by Individuals and Organizations

In this paper, we explore the factors influencing the adoption of Human Resources (HR) Analytics by HR professionals in large Palestinian enterprises. A convenience sample of 151 HR professionals from the service and manufacturing sectors participated in a questionnaire-based survey. The study identified self-efficacy, performance expectancy, effort expectancy, resource availability, quantitative self-efficacy, data availability, and social influence as the most significant factors positively influencing individual acceptance and adoption of HR Analytics. Fear appeals, on the other hand, had no significant effect. The study proposes a conceptual framework to help policymakers in organizations understand how to adopt HR Analytics

Diagnostic study of Cryptosporidiosis in sheep in Al-Qadisiyah province

The present study was designed and conducted during the period from September 2015 until April 2016 to evaluate the microscopic features of the Cryptosporidium parasite and using of an ocular micrometer for determination of length and width of oocysts. One hundred (100) fecal samples were collected from sheep from different areas in AL-Qadisiyah province. Results of the microscopic examination showed that the oocyst of parasite appeared oval or spherical in shape, measured from (4.5-5) μm, with a dark pink or red in color on a blue ground. Fifty-one 51(51%) sheep out 100 cases were positive. The highest rate of infection was observed in (1-3) years of age with significant differences at (P0.05). According to the area the highest rate of infection was (100%) that observed in Al-Shamia while the least rate of infection was (11.1%) that observed in Al-bidder and the different results showed in other regions with a significant difference at (P<0.05)

ASSESSMENT OF GROUNDWATER QUALITY FOR DRINKING IN TUZ KHURMATU AREA, SALAHADDEN GOVERNORATE – IRAQ

The results of climatic data that obtained from Tuz Khurmatu meteorological station show actual evidence in the climatic changes, which are indicated by remarkable decreases in the means of annual rainfall, relative humidity percentages and with increases of the means of annual minimum and maximum temperatures. The unconfined aquifer of Adaim river basin is recharged mainly from rain water. Since this source is scarce, the aquifer gains its water slowly in a rate less than the rate of losing by both evaporation and abstraction wells. The water Quality Index (WQI) has been used to assess suitability of groundwater quality for human drinking purpose in Tuz Khurmatu area. Groundwater samples were collected in September (2010) and March (2011) from twenty wells and analyzed for their physicochemical characteristics such as pH, total dissolved solids, Electrical Conductivity, sodium, calcium, magnesium, potassium, bicarbonate, sulphate, chloride and nitrate. Each parameter was compared with its standard permissible limit as prescribed by Iraqi drinking water standards. The results showed that WQI values for the groundwater of the study area ranged from 27.25 to 139.81. Based on the WQI classification majority of the samples are falling under excellent to good water category and suitable for drinking water purpose

Hemodynamics during the 10-minute NASA Lean Test: evidence of circulatory decompensation in a subset of ME/CFS patients.

BACKGROUND: Lightheadedness, fatigue, weakness, heart palpitations, cognitive dysfunction, muscle pain, and exercise intolerance are some of the symptoms of orthostatic intolerance (OI). There is substantial comorbidity of OI in ME/CFS (Myalgic Encephalomyelitis/Chronic Fatigue Syndrome). The 10-minute NASA Lean Test (NLT) is a simple, point-of-care method that can aid ME/CFS diagnosis and guide management and treatment of OI. The objective of this study was to understand the hemodynamic changes that occur in ME/CFS patients during the 10-minute NLT. METHODS: A total of 150 ME/CFS patients and 75 age, gender and race matched healthy controls (HCs) were enrolled. We recruited 75 ME/CFS patients who had been sick for less than 4 years (\u3c 4 ME/CFS) and 75 ME/CFS patients sick for more than 10 years (\u3e 10 ME/CFS). The 10-minute NLT involves measurement of blood pressure and heart rate while resting supine and every minute for 10 min while standing with shoulder-blades on the wall for a relaxed stance. Spontaneously reported symptoms are recorded during the test. ANOVA and regression analysis were used to test for differences and relationships in hemodynamics, symptoms and upright activity between groups. RESULTS: At least 5 min of the 10-minute NLT were required to detect hemodynamic changes. The \u3c 4 ME/CFS group had significantly higher heart rate and abnormally narrowed pulse pressure compared to \u3e 10 ME/CFS and HCs. The \u3c 4 ME/CFS group experienced significantly more OI symptoms compared to \u3e 10 ME/CFS and HCs. The circulatory decompensation observed in the \u3c 4 ME/CFS group was not related to age or medication use. CONCLUSIONS: Circulatory decompensation characterized by increased heart rate and abnormally narrow pulse pressure was identified in a subgroup of ME/CFS patients who have been sick for \u3c 4 years. This suggests inadequate ventricular filling from low venous pressure. The 10-minute NLT can be used to diagnose and treat the circulatory decompensation in this newly recognized subgroup of ME/CFS patients. The \u3e 10 ME/CFS group had less pronounced hemodynamic changes during the NLT possibly from adaptation and compensation that occurs over time. The 10-minute NLT is a simple and clinically useful point-of-care method that can be used for early diagnosis of ME/CFS and help guide OI treatment

Exploring the Knowledge, Attitude and Practice Regarding Hepatitis B Infection Among Dental Students in Saudi Arabia: A Cross-Sectional Study

BACKGROUND: Hepatitis B infection is a universal health problem. Worldwide, 5% of health-care-related injections continued unsafe. Dentist considers being at high-risk group for cross infection. Therefore, their knowledge and practice towards Hepatitis B virus (HBV) positive patients should be at an optimal level. AIM: The current study is aimed to evaluate and comparison of the knowledge, attitude and practice of Saudi dental students and interns towards HBV infection. METHODS: A self-explanatory questionnaire comprising of 16 questions was designed to assess and compare students’ knowledge, attitude and risk perception regarding hepatitis B infection among dental students across Saudi Arabia. RESULTS: The response rate was 91.6% the overall knowledge of the participants was poor. The attitude was fair, with the female show a significant difference in attitude and practice (P-value &lt; 0.05). The overall practice was good, 78.1% was vaccinated against HBV, and 73.2% stated that they regularly use personal protection equipment. The higher levels show a good attitude and practice compared with the lower levels; the difference was significant (P value &lt; 0.05). CONCLUSION: The overall knowledge was below average, continuous health education courses are mandatory

Study of Smoking Effects on Total WBCs Count and Phagocytic Activity of Clinical Laboratories Workers Blood in Al-Muthana Governorate

Clinical Laboratory workers undergo a periodic checkup as biosafety management's procedures; due to that, they are in continuous exposure to pathogens during such work. Smoking is a problem for healthy peoples, but as laboratory technicians, this subject was not under seeking before. Total WBCs count is a test listed in the clinical form depended by Ministry of Health, while phagocytosis activity is not. These two clinical parameters were estimated in this research in healthy volunteers Blood; working in Al-Muthana Governorate clinical laboratories, NBT test was used for Neutrophils activity evaluation. Results showed elevation in WBCs Total Counts and decrease in phagocytic activity; smoking caused more elevation in total count and lower percentages of active phagocytic Neutrophils comparing with the non-smokers obtained values. Conclusion: Periodic checkup in Iraq should be updated and smoking status must be included

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

Health Impact Assessment Associated with Exposure to PM10 and Dust Storms in Kuwait

Little information is available on the assessment of health impact concerning the Middle Eastern dust storms and PM10 concentration levels despite the aridity of the region and frequent dust storms occurring in this part of the world. A prospective study was conducted to determine the association between dust particles and morbidity and mortality rates for respiratory and cardiovascular diseases in Kuwait. Spearman and Pearson’s correlations were used to identify such associations. Results revealed a significant correlation between dust storms, suspended dust and rising dust (p &lt; 0.01). Correlation between the occurrence of respiratory and cardiovascular diseases and dust storms showed that PM10 concentrations were significantly correlated with bronchial asthma at the 0.05 level (Pearson r = 0.292). Significant correlations at the 0.01 level were shown between bronchial asthma and both acute lower respiratory tract infection (r = 0.737) and acute upper respiratory tract infection (r = 0.839). Respiratory and cardiovascular mortality rates were both equal to 0.62 per 10,000 persons, each corresponding to 8.7% proportionate mortality rate. This study provides a good evidence of the consistent relationship between dust storm events, PM10 concentration levels, and respiratory diseases
