Angular velocity and elevation angle: the proposed human model scalable tracking model using linear regression

A scalable tracking human model was proposed for recognizing human jogging and walking activities. The model aims to detect and track a particular subject by using wearable sensor. Data collected are in accelerometer readings in three axes and gyroscope readings in three axes. The development of proposed human model is based on the moderating effects on human movements. Two moderators were proposed as the moderating factors of human motion and they are angular velocity and elevation angle. Linear regression is used to investigate the relationship among inputs, moderators and outputs of the model. The result of this study showed that the angular velocity and elevation angle moderators are affecting the relation of research output. Acceleration in x-axis (Ax) and angular velocity in y-axis (Gy) are the two main components in directing a motion. Classification between jogging and walking motions was done by measuring the magnitude of angular velocity and elevation angle. Jogging motion was classified and identified with larger angular velocity and elevation angle. The two proposed hypotheses were supported and proved by research output. The result is expected to be beneficial and able to assist researcher in investigating human motions

Colour Perception on Facial Expression towards Emotion

This study is to investigate human perceptions on pairing of facial expressions of emotion with colours. A group of 27 subjects consisting mainly of younger and Malaysian had participated in this study. For each of the seven faces, which express the basic emotions neutral, happiness, surprise, anger, disgust, fear and sadness, a single colour is chosen from the eight basic colours for the “match” of best visual look to the face accordingly. The different emotions appear well characterized by a single colour. The approaches used in this experiment for analysis are psychology disciplines and colours engineering. These seven emotions are being matched by the subjects with their perceptions and feeling. Then, 12 male and 12 female data are randomly chosen from among the previous data to make a colour perception comparison between genders. The successes or failures in running of this test depend on the possibility of subjects to propose their every single colour for each expression. The result will translate into number and percentage as a guide for colours designers and psychology field

A review of natural fiber reinforced poly(Vinyl alcohol) based composites: application and opportunity

Natural fibers are fine examples of renewable resources that play an important role in the composites industry, which produces superior strength comparable to synthetic fibers. Poly(vinyl alcohol) (PVA) composites in particular have attracted enormous interest in view of their satisfactory performance, properties and biodegradability. Their performance in many applications such as consumer, biomedical, and agriculture is well defined and promising. This paper reviews the utilization of natural fibers from macro to nanoscale as reinforcement in PVA composites. An overview on the properties, processing methods, biodegradability, and applications of these composites is presented. The advantages arising from chemical and physical modifications of fibers or composites are discussed in terms of improved properties and performance. In addition, proper arrangement of nanocellulose in composites helps to prevent agglomeration and results in a better dispersion. The limitations and challenges of the composites and future works of these bio-composites are also discussed. This review concludes that PVA composites have potential for use in numerous applications. However, issues on technological feasibility, environmental effectiveness, and economic affordability should be considered

Comparative genomic analysis of a multidrug-resistant Staphylococcus hominis ShoR14 clinical isolate from Terengganu, Malaysia, led to the discover of novel mobile genetic elements

Staphylococcus hominis is a coagulase-negative Staphylococcus (CoNS) commensal capable of causing serious systemic infections in humans. The emergence of multidrug-resistant S. hominis strains is of concern but little is known about the characteristics of this organism, particularly from Malaysia. Here, we present the comparative genome analysis of S. hominis ShoR14, a multidrugresistant, methicillin-resistant blood isolate from Terengganu, Malaysia. Genomic DNA of S. hominis ShoR14 was sequenced on the Illumina platform and assembled using Unicycler v0.4.8. ShoR14 belonged to sequence type (ST) 1 which is the most prevalent ST of the S. hominis subsp. hominis. Comparative genomic analysis with closely related strains in the database with complete genome sequences, led to the discovery of a novel variant of the staphylococcal chromosome cassette mec (SCCmec) type VIII element harboring the mecA methicillin-resistance gene in ShoR14 and its possible carriage of a SCCfus element that encodes the fusidic acid resistance gene (fusC). Up to seven possible ShoR14 plasmid contigs were identified, three of which harbored resistance genes for tetracycline (tetK), chloramphenicol (catA7), macrolides, lincosamides, and streptogramin B (ermC). Additionally, we report the discovery of a novel mercury-resistant transposon, Tn7456, other genomic islands, and prophages which make up the S. hominis mobilome

Position and shape estimation using double integration of acceleration

This study investigates and acts as a trial clinical outcome for human motion and hand behaviour analysis in consensus of subject’s habit related quality of life. It was developed to analyse and access the quality of human hands motion that can be used in hospitals, clinics and human motion researches. It aims to establish how widespread the quality of life effects of human motion. An experiment was set up in a laboratory environment with conjunction of analysing human hand motion and its habit. Sensors are attached on both wrists. The instruments demonstrate adequate internal consistency of findings: 1. it is hard for subject to draw a perfect circle whether using left or right hand and this is supported by descriptive statistical data and simulation of drawings. 2. Subject’s left hand (right handed) unable to draw a perfect circle or square. These two drawings are looks alike and it is supported by double integration technique. A simple and informative representation for statistical data, simulation of drawings were developed to demonstrate the results

Identification, disclosure and education support of domestic violence and sexual abuse (DVSA) victims

Aim: Supporting Domestic violence and sexual abuse (DVSA) victims at education paradigm. Objective: To find practical methods of disclosing, identifying, and supporting DVSA victims in the education paradigm. Methodology: A phenomenological descriptive literature review study explores what is known from different authors about identification, influence, disclosure tools and support of DVSA victims to clarify the phenomenon, approaches of disclosure tools and victims’ support at education paradigm. Conclusion: Improving factual knowledge and awareness among students and teachers. National policies are mandating the teaching of violence prevention in the national curricula, allocation of budgets, and resources. The need for more comprehensive studies on this subject, educating educators about this paradigm, structuring effective practical disclosure aids, and raising funds and professionals for highly flexible individualised methods of victim’s support. Recommendations Tools chosen should consider the target population, screeners’ skills and experience, and the evaluation’s objective and context. Educators and healthcare providers must ensure that adequate referral and follow-up are provided to those identified through screening to ensure the efficacy of DVSA interventions. Teacher’s lack of confidence, conviction, and expertise could jeopardise the intended message; educator’s training is recommended. To establish DVSA forum at educational institutes, starting with the “digital generation” at tertiary education or secondary and lower educational levels. Students can write, discuss, share, and disclose at this forum anonymously. The details are accessed by a specialised individual who can implement policies and communicate with students who disclosed the information or are suspected of DVSA
