The study aimed to create an enhanced monitoring and management system of patients’ medical records for hospital clinics to provide easy identification of patients and give easy access to the doctors and nurses regarding patient’s medical information. A face recognition system to access patient information was created by means of hardware and software integration. The hardware consisted mainly of a webcam for capturing the image of the patient’s face. The webcam, together with the servos were connected to a gizDuino v4.0 microcontroller to allow the camera to track the face. An interface and software program using C# (.Net Framework 4) with the use of Viola-Jones algorithm code sources for face detection, Eigen-faces sources for face recognition, and Arduino IDE to program the microcontroller was developed. The content of the medical record were based on the conducted survey answered by medical professionals and saved in MySQL database. With the use of five-point Likert scale, the user-acceptability of the system was tested by doctors, nurses, medical technologists, and other medical professionals. A good result was obtained where 8 out of 10 questions were rated as ‘strongly agreed’ and the other two were rated ‘agreed’ by the survey respondents. The test for face detection yielded a 100% result and out of 30 trials conducted for face recognition, 25 were recognized with its respective record. This indicates that the system is functional and of good quality. © 2016 Penerbit UTM Press. All rights reserved.

17α-Ethinylestradiol (EE2) is a synthetic estrogen, which is found to resist biodegradation. It has been observed that EE2 eludes treatment in most conventional treatment facility. Batch experiments on the biological removal of EE2 and Bisphenol A (BPA) using a highly active nitrifying liquid inoculum (NLI) was investigated. NLI had shown the capacity to remove EE2 at a rate of 8 μg EE2 g−1 MLSS h−1. Heterotrophic isolates taken from an aerated fixed bed reactor did not show any capacity to remove EE2 but when combined with NLI, complete removal of EE2 was achieved. This clearly linked the important role of nitrifiers in the biological removal of EE2. This relation was tested by using allylthiourea (ATU) to inhibit the first step in nitrification. It is surprising to note that even with the addition of ATU, EE2 removal was not inhibited. NLI had also shown 100% removal of 1 mg L−1 BPA within 3-4 d. The degradation of BPA follows zero order kinetics with a rate of 0.254 mg L−1 d−1. Batch tests were also conducted to determine the effect of the addition of ammonium in the rate of biological removal of EE2. Results showed that degradation of EE2 obeys first order kinetics at a rate of 0.11 d−1 when no ammonium was added and increases to 0.23 d−1 upon addition of ammonium. This suggests that the presence of nitrifiers enhanced the removal of EE2. Results obtained indicate that BPA is more readily biodegradable as compared to EE2. © 2013, (Chinese Institute of Environmental Engineering). All rights reserved.

Volatile organic compounds (VOCs) represent an important class of air pollutants, however their concentration levels in developing countries have scarcely been reported in literature. Therefore, concentration levels of 60 VOCs were determined at 27 urban and industrial locations in seven different cities in Ethiopia, Vietnam, the Philippines and Bangladesh between 2011 and 2014. Active sampling using Tenax TA as a sorbent was employed followed by TD-GC-MS analysis using internal standard calibration. It was found that TVOCs concentration levels in Dhaka, Bangladesh (arithmetic mean: 343 and 399 μg/m3 for urban and industrial campaign, respectively) were more than 10 times higher when compared to TVOCs levels observed in Mekelle, Ethiopia. ∑BTEX concentration at street sites ranges from 36 μg/m3 in Mekelle, to 100 and 250 μg/m3 in Hanoi, Vietnam and Dhaka, Bangladesh, respectively. The indoor to outdoor concentration ratios were found to be dependent on the country, type of environment, VOC compound and outdoor reference location. The highest Ozone Formation Potential (OFP, 2150 μg/m3), calculated from the same set of seven aromatic VOCs, was obtained at the street site in Dhaka. This OFP value is a factor three and four times higher than the OFP value observed at the street sites in Hanoi, and Manila, respectively. Finally, the Cumulative Cancer Risk (CCR) calculated for four carcinogenic VOCs ranged from 97 × 10-6 in urban Mekelle to 299 × 10-6 in urban Dhaka. This work provides for the first time comparisons of CCR in urban and industrial environments in the selected developing countries. © 2015 Elsevier Ltd.

Gearing on sustainable technology, two waste materials, coco coir dust and UPVC were utilized to produce a wood-tile quality, high density composite board material. Adopting the technology in producing fiberboards, the use of UPVC as binder to combine with dried coir dust (5% moisture content) was investigated. Three mix ratios of UPVC: Coir Dust were used: 80:20, 70:30 and 60:40. The produced board from each combination was then subjected to mechanical and physical property tests. Their properties were compared using the analysis of variance. The mixing process involves the use of two-roll mill machine operating at 204°C while the pressing involves the heat press machine at 108°C and pressure of 450 psi for 3minutes. The finished products highlight a glossy brown surface comparable to a wood tile, and can be readily manufactured without the additional veneer coating. Physical properties of the 3 ratios were tested against ordinary board. All 3 ratios exhibit 0% Water Absorption (WA) and Thickness Swelling (TS) while ordinary board showed 28.5% WA and 16.5% TS. Mechanical tests for the 80:20 ratio yielded a highest mean value of 55KPa·m on Impact Strength (IS) and 68.85MPa on Modulus of Rupture (MOR) while ordinary boards yielded 50KPa·m on IS and 7.51MPa on MOR. The least mean on different properties of the bio-composite material were compared with the means of commercial board product. This study found that the PVC-Coir Dust combination exhibited highly satisfactory performance based on the physical and mechanical properties as compared to the ordinary board. © 2015, International Journal of GEOMATE.

The current design and construction of the tricycle in the Philippines is geared more towards aesthetics, which sometimes neglects the passengers comfort and safety. Risk assessments were first conducted to come up with an innovative design of a tricycle that would be safe and comfortable to ride. Rapid Upper Limb Assessment was conducted to assess the postural risk of the passengers using surveys and questionnaires based on the Cornell Musculoskeletal Discomfort Questionnaire, face-to-face interviews and written questionnaires for passengers, drivers, and for the 'latero' to determine the demand of the users, muscular discomfort and satisfaction. Quality Function Deployment was used to determine the initial specifications by evaluating the customer requirements. The point of view of the passengers was determined through survey questionnaires and the analysis of the modifications responsive to these needs was set in order to ensure that the passengers' needs are met. Failure Mode and Effect Analysis served as an efficient method in the risks involved with the use of the product. Lastly, ergonomic principles were applied to appropriately dimension the passengers' cabin and the back ride by applying the concepts of Anthropometry. © 2015 IEEE.
