Sick Building Syndrome in Apartment Buildings in Jordan

The present study was conducted to investigate the concept of sick building syndrome which has recently been receiving attention to improve the indoor environmental quality in housing projects in Jordan. Apartment buildings were selected in three locations in Jordan; Amman, Irbid and Zarqa to represent different climatic regions in Jordan. The methods of enquiries were based on observation(physical architectural and detailed analysis of the buildings),calculations of the environmental factors which affect indoor air quality and healthy environment and questionnaires designed and distributed to investigate occupants’ perception in terms of health and building conditions. The findings revealed that there were significant differences among geographical locations of apartment buildings in Jordan. Zarqa had the most severe condition because of the crowdness in the urban setting and the extreme weather conditions. Moreover, building physical configuration and attributes such as window sizes and types, envelope design, location of the apartment in the building, orientation and building layout had significant effects on the concept of the sick building syndrome

HbA1c, Total IgE, and TNFα as Blood Markers for Long Exposure of Traffic-related Fine Particles: A Study on Mechanics at Vehicle Test Stations

Particulate matter such as hydrocarbons, sulfur oxides (SOx), and nitrogen oxides (NOx) dominate air pollutants released from vehicle emission and are notorious for their adverse health effects. High concentrations of traffic-related air pollutants in urban areas are sometimes neglected by society despite being harmful to human health. This study aimed to discover the blood markers of traffic-related particulatematter in humans. The study collected traffic-related particulate matter 2.5 (PM2.5) data from 32 mechanics working in vehicle emission test stations in Pulo Gadung and Ujung Menteng, Jakarta. Every measurement was made according to the Environmental Protection Agency Isopropil Alcohol 10A (EPA IP 10 A) method. Bloodand urine samples were collected from 43 mechanics as an exposed group and 23 non-exposed workers as a control. Profile lipid, glycated haemoglobin (HbA1c), total Imunoglobin (IgE), calcium, and Tumor Necrosis Factor-α (TNFα) in blood were measured in all 66 samples. Urinary 1-hydroxypyrene (1-OHP) was detected in 21exposed group samples using a liquid chromatography fluorescence detector. As a result, the mean concentration of PM2.5 from mechanics was 306.91 ± 99.19 µg/m3. Independent t-test results of the biochemical analysis from blood examination within those groups showed a significant difference in several parameters such as triglyceride (p = 0.005), HbA1c NGSP (p = 0.01), HbA1c IFFC (p = 0.01), total IgE (p = 0.02), calcium (p = 0.03), and TNFα (p = 0.00). Total cholesterol and personal PM2.5 exposure showed a moderate correlation with r = 0.355 (p = 0.046). Urinary 1-OHP mean concentration from the exposed group was 21.61 ± 10 µg/L. In conclusion, HbA1c, IgE, and TNFα can be considered as a blood marker for long exposure to PM2.5, while further study is needed to determine the possibility of using 1-OHP as non-invasive method to detect the particulate matter exposure in humans, particularly from traffic-related sources.

Efficient error correcting scheme for chaos shift keying signals

An effective error-correction scheme based on normalized correlation for a non coherent chaos communication system with no redundancy bits is proposed in this paper. A modified logistic map is used in the proposed scheme for generating two sequences, one for every data bit value, in a manner that the initial value of the next chaotic sequence is set by the second value of the present chaotic sequence of the similar symbol. This arrangement, thus, has the creation of successive chaotic sequences with identical chaotic dynamics for error correction purpose. The detection symbol is performed prior to correction, on the basis of the suboptimal receiver which anchors on the computation of the shortest distance existing between the received sequence and the modified logistic map’s chaotic trajectory. The results of the simulation reveal noticeable Eb/No improvement by the proposed scheme over the prior to the error- correcting scheme with the improvement increasing whenever there is increase in the number of sequence N. Prior to the error-correcting scheme when N=8, a gain of 1.3 dB is accomplished in Eb/No at 10-3 bit error probability. On the basis of normalized correlation, the most efficient point in our proposed error correction scheme is the absence of any redundant bits needed with minimum delay procedure, in contrast to earlier method that was based on suboptimal method detection and correction. Such performance would render the scheme good candidate for applications requiring high rates of data transmission

Analysis of the Risk Factors Associated with Coronary Heart Disease for Cement Factory Workers

Cardiovascular disease is the leading cause of death globally each year. The study was conducted to determine the risk factors for coronary heart disease (CHD) based on the results of a treadmill test data. This cross-sectional study included 173 employees from medical check-up (MCU). The results showed that the risk of acquiring CHD had statistically significant associations with age, hypertension, total cholesterol, Low Density lipoprotein (LDL), diabetes mellitus, smoking, body mass index (BMI), shift, and stress based on a treadmill test, but CHD risk was not found to have an association with High Density Lipprotein (HDL). After conducting logistic regression, seven risk factors of CHD were found: age, hypertension, total cholesterol, diabetes mellitus,smoking, BMI, and stress. Keywords: Risk Factors, Coronary Heart Disease, Treadmill tes

Effects of Shift Work on Chronic Fatigue Symptoms among Automotive Part Workers

Shift work is associated with negative effects on sleep and performance as well as with chronic fatigue. The goal of this cross-sectional study was to explore chronic fatigue symptoms among automotive part workers. Chronic fatigue symptoms were measured using the Piper Fatigue Scale (PFS) questionnaire. Fatigue measurementresults showed that about 50.7% of die-casting part shift workers had symptoms of mild fatigue, and 49.3% had symptoms of severe fatigue. The risk factors significantly related to fatigue symptoms include job design, overtime, physical workload, commute time, and health status. This study shows that shift work might affectfatigue symptoms among manufacturing workers. It seems necessary to implement ergonomic continuous improvement programs for more appropriate shift work as well as reducing working hours.

Design of smart wireless changeover for continuous electric current feeding from power sources of variable capacities

Electric power has become a vital element for life today. Despite this importance, electric power consumers in Iraq suffer from the problem of noncontinuity and daily electric power supply interruption. This problem led to the use of various sources of electric power as an alternative to compensate for the shortage of electric power provided by the Iraqi national grid. In this work, a smart wireless changeover device is designed using wireless sensor networks technology aiming to solve problem caused by the multiplicity of power sources received at home and governmental buildings in Iraq by controlling operation of some electrical devices (which consume high current) in the home or workplace automatically when changing source of electricity from one to another. This solution will help to ensure the continuity of electric current feeding from power sources of variable capacities, also, to rationalize power consumption by assigning an operation priority to electric devices. Furthermore, a statistical measurement as a case study was performed in a building with a total power consumption of 160.8 KW/h. The result showed that the device functions effectively and it is capable of achieving an average saving in power of about 50% to 86% depending on the applied priorities and case study scenario

An Improved M-ary Modulation Scheme Based on Chaotic Dynamics, Journal of Telecommunications and Information Technology, 2019, nr 4

This paper proposes an improved chaos-based M-ary modulation system. It reproduces deterministic chaotic dynamics to create M-ary non-coherent modulation. The proposed modulation system transmits data using autonomous chaotic sequences. It separates the chaotic dynamics through the use of interleavers and realigns them through the use deinterleavers. The simulation results show that the improved scheme overperforms its traditional counterpart. The degree of improvement grows as the M-ary order is increased, with a penalty of increased system complexit

Impoliteness in EFL Complaints: Exploring Its Intentions and Motivating Factors

The present study investigated intentions and motivating factors of using impoliteness in interlanguage complaints by EFL learners. Empirical data were elicited by means of oral discourse completion tasks and questionnaires from 42 Indonesian learners of English. Post-structured interviews were conducted to obtain the intentions and reasons of deploying impoliteness in the complaints. The results reveal that impoliteness is triggered by three general motivating factors; speaker-related factors, target person-related factors, and contextual factors. A number of intentions of deploying impoliteness are found, and they suggest that impoliteness is a means to an end rather than an end itself
