1. Ergonomics Investigation of Workers in Construction Glass and Glazing Trade Using the Rapid Entire Body Assessment (REBA) Method
Zahra Jabbarani Torghabeh and Terry L. Stentz and Micheal Jorgensen
International Journal of Advances in Engineering & Technology (IJAET), Volume 13 Issue 3, pp. 57-71, June 2020.
The Construction Glass and Glazing (CGG) trade was investigated to identify the most physically stressful work tasks and systematically score and rank the tasks by the required action level using the Rapid Entire Body Assessment (REBA) method. Data were collected by taking pictures and notes at five construction sites. In total, 30 construction glass and glazing workers were observed over 54 days across five CGG construction companies. Manual Materials Handling (MMH) resulted in the highest REBA score for frame installation, glass/panel installation, and loading/unloading tasks (8.8, 8.5, and 7.5 respectively). Screwing/unscrewing/drilling, and caulking activities were among activities with a medium REBA action level of 2 (necessary). Medium to high REBA scores for CGG tasks emphasize a need for future ergonomics interventions to eliminate or reduce the risk of Work-Related Musculoskeletal Disorders (WRMSDs) in this trade.

2. Corrosion Inhibition Effect of Thiourea on Mild Steel in Hydrochloric Acid Contaminated with Chlorine

Inexpensive industrial hydrochloric acid, containing chlorine (Cl2) and other chlorinated organic compound contaminants, generally comes from the recovery of chlorinated organic compounds. The objective of this work is to evaluate, based on laboratory tests, the performance of the corrosion inhibitor (thiourea) in protecting carbon steel when immersed in hydrochloric acid contaminated with chlorine. In this evaluation, mass loss tests and electrochemical polarization tests were conducted under the following conditions: a concentration of hydrochloric acid of 5, 10, and 15% (by mass); chlorine (Cl2) was added to the acid in quantities of 50 - 5000 mg/L; the concentrations of thiourea were 250, 500, and 1000 mg/L; and the temperature was maintained at 25 degree Centigrade. Gravimetric and polarization tests carried out using mild steel coupons show a significant loss of thiourea inhibitory protection because there is an increase in the concentration of hydrochloric acid associated with an increase in chlorine content

3. Assessment of Physical Risk Factors using the Posture, Activity, Tools, and Handling (PATH) Method in Construction Glass and Glazing Work.
Zahra Jabbarani Torghabeh and Bryan Buchholz and Terry L. Stentz
International Journal of Advances in Engineering & Technology (IJAET), Volume 13 Issue 3, pp. 80-93, June 2020.
This study analysed construction glass and glazing (CGG) work tasks to determine those ergonomics risk factors that pose the greatest risk for back discomfort, pain, and injury using the PATH Method. A total of 19,300 observations were made on 30 field workers during the curtainwall, storefront, and panelling operations. Manual Material Handling (MMH) was a major activity for all tasks except finishing jobs. Carry/hold materials ranked at the top among MMH activities. CGG workers often had weights in their hands. CGG workers spent 27.2% of their time in non-neutral trunk postures, 21% of the time they had one/two elbow(s) at/above shoulder height, and 92.2 % of the time they were standing/walking. The percentage of time that CGG workers were observed in different MMH activities, holding a weight, observing in nonneutral postures differed significantly between job tasks. The results of this study provided a baseline database for future evaluations of ergonomics interventions.

4. Comparative Analysis of Fault Diagnosis in Transmission Line using Soft Computing Techniques
Gyanesh Singh, A.Q. Ansari, Md. Abul Kalam
International Journal of Advances in Engineering & Technology (IJAET), Volume 13 Issue 3, pp. 94-106, June 2020.
This paper proposes soft computing techniques for short circuit classification, location and nature for the different types of short circuit in long transmission multi-terminal line. Author proposes various soft computing methods e.g. Fuzzy Logic system (FLS), Python and Nonlinear auto regression with exogenous input (NARX) Artificial Neural Network (ANN). A comparative analysis proposes in this paper for accuracy, feature extraction for future fault identification and for suitable designing of protective devices such as relay and circuit breaker for separating the healthy section from faulty section. The above proposed soft computing techniques also provide a means for reliability of power supply to the consumers like industrial, agricultural, commercial and domestic. For better designing of protective devices, it is absolute necessity of accuracy as well as precision.

International Journal of Advances in Engineering & Technology (IJAET), Volume 13 Issue 3, pp. 107-115, June 2020.
This paper presents a technological study in the areas of mechatronics engineering and assistive technology. It's about how to help in the physiotherapy exercises of the lower limbs of children with cerebral palsy. The study happens to check the possibility of elaborating on a product that can improve the motor capacity of these children. Also, providing rehabilitation and social inclusion and making life and everyday life more comfortable, having as main objectives the construction of the product, and obtaining results on their efficiency. This investigation discusses the theme of Cerebral Palsy (CP). The methodology of technological research was used, from the detection of the problem and the resolution proposal through the design and creation of a new product. Afterward, we applied a questionnaire answered by doctors and teachers in the area of physiotherapy, from which data emerged about the efficiency of the product. They show that the product is innovative, attractive, and of great use not only for the child with cerebral palsy but also for the adolescent and adult, bringing gains in independence, self-esteem, and functional and psychological development.
