The Development and Testing of Automatic Crutches for Disable Person

2024-01-11T06:32:26+00:00

Walking aids such as canes, crutches, and walkers play a crucial role in improving a patient's base support, balance, and independence. However, conventional crutches with manual height adjustment mechanisms pose challenges for users, especially on uneven surfaces, leading to device damage and incorrect height settings. To overcome this issue, this paper introduces a crutch design that incorporates an automatic height-adjustment feature tailored to the patient's individual height. It utilises a linear actuator for height adjustment and soft materials for padding. To assess its functionality and effectiveness, a comprehensive evaluation is conducted, comparing the proposed automatic crutch to traditional axillary crutches. Experimental results demonstrate that the innovative device facilitates enhanced mobility on uneven surfaces, aids in climbing stairs, and offers personalised comfort for sitting or standing. Moreover, the cushion pad integrated into the design effectively reduces friction and pressure between the armpit and crutches, thereby mitigating the risk of armpit injuries. This research signifies a significant advancement in walking aid technology, addressing critical issues associated with manual adjustment and improving the user experience using crutches.

Transformation of Water to Evaporation and Long Range Discharge System

2023-10-17T03:25:13+00:00

Evaporation innovations through nozzle sprinklers and long range discharge systems are created based on the occurrence of stagnant floods at identified locations. Stagnant floods are water in an area that does not recede for 10 days and at the same time can damage the activities of the population such as agriculture, fishing, and other activities, this will also increase the cost of repairing existing activities after the flood. This innovation will test 5 types of nozzles of various designs as well as various forms of spray into the air in the laboratory and from this study will determine which nozzle is most suitable to be installed during a stagnant flood in an area. In addition, this innovation is equipped with a long range discharge water system where if the flood water is too high then this system is used to move the flood water. Adjustable arc spray nozzle, field sprinkler, green garden, fountain nozzle, and fan or vapor blower have been tested where green garden spray type and fan or vapor blower will produce high evaporation which is between 9.5 percent to 18 percent but the water discharge from stagnant floods is low at 4.8 liters in 10 minutes. While the fountain spray nozzle also shows a high percentage of evaporation which is up to 15 percent and water discharge is also high is 409 liters in 10 minutes. However, the selection factor of the type of spray nozzle depends on the objective or requirements. The objective of the project is to determine the effectiveness of the sprinkler nozzle design and water discharge before being installed at the site.

Employee performance through self efficacy : A case study of Malaysia

2024-02-06T05:00:49+00:00

This paper seeks to determine the impact of self-efficacy on employee performance in the insurance business of Malaysia. The paper delineates the fundamental components of self-efficacy and emphasises its significance in shaping the culture of the service industry to enhance productivity. This can be influenced by factors such as job satisfaction, motivation, and stress. Additionally, it highlights the insurance company's inclination towards developmental interventions as a response to environmental changes, both within Malaysia and globally. This study offers insights into the potential impact of self-efficacy on employee performance by examining existing literature and adding case examples

Assessing Groundwater Quality for Agricultural Applications in Bemban, Melaka: Implications for Sustainable Farming Practices

2023-10-11T01:21:36+00:00

Groundwater's significance in safeguarding food security becomes even more critical, particularly amidst the unpredictability of climate change. The utilization of groundwater in Bemban remains significantly underutilized, despite the fact that the local villagers engage in small-scale agricultural practices with a focus on sustainable productivity. Several agriculture practitioners rely on river water for irrigation purposes; however, the combination of a hot climate and limited water availability adversely affects crop growth, leading to stunted plants and diminished agricultural yields. This research aims to evaluate the groundwater and river water quality in comparison to guidelines from the National Water Quality Index Classification and Water Quality Interpretation Guidelines for Irrigation in Bemban, Melaka. Two groundwater sampling wells along with a nearby river were utilized to collect representative samples, which were subsequently analyzed for various key characteristics include pH, ammoniacal nitrogen (AN), total suspended solids (TSS), chemical oxygen demand (COD), dissolve oxygen (DO), biochemical oxygen demand (BOD), electrical conductivity (EC), total dissolved solids (TDS), and turbidity. The test results were compared with the guidelines provided by the National Water Quality Index Classification (NWQS) and Water Quality Interpretation Guidelines for Irrigation. The results show the parameter pH and COD are within the acceptable tolerance range, indicating that The water is able to be used for irrigation. The research findings will play a crucial role in persuading agriculture practices to utilize their well water for irrigation purposes. This will contribute to enhancing the overall efficiency and sustainability of agricultural practices in the region. Further investigations should focus on finding the parameters for Groundwater Quality Index (GWQI) for Bemban’s agriculture landscape

An Innovation of Hearing Aid

2023-01-08T12:34:22+00:00

– The human ear is an organ of hearing and balance. It detects and analyzes sound through a transduction mechanism, which is the process of converting sound waves into electrochemical impulses. Auditions cannot be adequately performed if the anatomy is abnormal. Hearing aids are small amplifiers that fit into the ear, used by people who are partially deaf. In this effort, adaptive hearing aids have been designed to improve hearing for the deaf. To improve hearing for deaf people, it should correct speech imperfections and adjust the volume of acoustic impulses intelligently. With the use of electret microphones, the sound is recorded from all sides. The signal emanating from it is first amplified using a low-pass filter. This paper is to diagnose the patient case scenario for the hearing-impaired patient, to identify the wearability issue of the patient's hearing aid. At the same time study, the theory of hearing loss and find out the causes of hearing loss, and provide a proposal for the design of suitable equipment for the study (3D). For this reason, we propose to make improvements to the old hearing aids by adding a volume knob
