Study on Remote Control Distance, Load Weight, and Users' Satisfaction of Remote-controlled Delivery Cart for COVID Patients

2024-06-14T15:58:49+07:00

The aims of this study were to determine a distance to receive a signal from a remote control, a weight that a cart can carry, and find users' satisfaction towards a remote-controlled delivery cart for COVID patients. The sample group included 10 medicine and food delivery staffs derived by purposive sampling technique. The instruments used in the research were an experimental result recording form and satisfaction questionnaires with the research statistics of mean and standard deviation. The results revealed that the delivery cart can receive radio signals from the radio remote control at a distance of 10 - 50 meters with good movement. However, when the distance increases (50-60 meters), the delivery cart cannot move. The load weight test results showed that with the load weight of 5 10 kilograms, the cart can move normally while as the weight of the delivery cart increased to 15 and 20 kilograms, the delivery cart moved slowly and then stopped. The users' satisfaction of the remote-controlled delivery cart reached the overall average score of 4.52±0.49 or the highest level of satisfaction. Therefore, the remote-controlled patient delivery cart for COVID patients can be used within a distance of 50 meters and the payload should not exceed 15 kilograms with the highest level of users’ satisfaction.

The efficiency test of the multipurpose portable hand wash basin shows that it operates from the system set as defined by the multipurpose portable hand wash basin programmed in 2 Arduino Uno boards which controls the release of a faucet water and tissues and on-off the lights at night. An Arduino Nano board controls opening and closure of a trash can. The upper part is installed with a 50-W solar panel LED light placed under the roof frame. The sensor controls the light operation when there is no sunlight at night. The front part consists of a set of a hand-soap dispenser, a faucet, a tissue dispenser, and a trash bin with a mirror on the wall. All devices work under the object detection sensor of which the program was written in the boards. When within the sensing range, the devices will operate according to hand-washing steps including soap dispensing after rinsing with water, tissue release, and opening and closure of the trash bin installed at the side of the basin. The lid of the trash bin is controlled by an on-off servo. The lower part is equipped with a device of 5-stage filtered water tank with 4 wheels for steady mobility and a pushing handle. At the back, there is a 30-liter water tank for water supply. The water is pumped into an automatic faucet. The used water is then filtered for grease and fat trapping before draining. The sample group reported their satisfaction on using the developed multipurpose portable hand wash basin at a very high level of 4.92.

Development of Plant-based Milk Products from Bambara Groundnut Powder by Foam-mat Drying Technique with Hot Air Drying

2024-06-14T17:07:42+07:00

The objectives of this research were to: 1) find the optimal amount of foaming of egg albumin powder foaming agent in the production of Bambara groundnut milk powder by 3 levels of foam-mat drying technique, i.e., 2%, 4%, and 6% by weight of the total ingredient content and 2) study the drying temperature with a hot air incubator suitable for drying Bambara groundnut milk powder at 3 temperature levels, i.e., 60, 70, and 80 degrees Celsius. The powder is then analyzed for physical quality, i.e., yield percentage, density, color, moisture, and solubility index. The results showed that: 1) the initial amount of the egg albumin powder foaming agent at 6% of the total weight was the sum of the highest foam concentration equal to 0.39±0.01 and 45.19±0.23 respectively reaching the statistical concentration (ps 0.05). The nutritional value of the foam is 68.91±3.44. 2) The drying temperature using the hot air oven at the lowest moisture content was 3.21%. The highest yield percentage was 54.71 % ±1.40. The brightness color value (L*), red value (a*), and yellow value (b*) were 78.82±0.06, 28.17 ±0.02, and 45.01±0.37 respectively. The water solubility index of the bean milk powder had the highest value, equal to 61.09±0.52, which was significantly different from other conditions (ps0.05). The yellow value (b") of both samples showed that the three conditions were not significantly different at 95% confident level while the higher temperatures resulted in the increase in brightness (L*) and redness (a*).

The Development of Low Sodium Sun Dried on Nile Tilapia Fish Products

2024-06-15T13:43:02+07:00

This study aimed at developing a method in using low sodium content to make sun-dried tilapia fish products. The objectives of this study were to: 1) study the production cost, chemical and physical quality testing of the sun-dried tilapia fish products and 2) develop the sun-dried tilapia fish products with low sodium by testing the sensory acceptance with a 5-point hedonic scale. The results of the production cost showed that the cost of the control group was at 94.62 baht per kilogram higher than that of the low-sodium tilapia group of 90.17 baht per kilogram. The results of the chemical and physical test of the sun-dried tilapia fish products showed a significant difference (P<0.05). In the determination of sodium chloride, the use of low sodium in the tilapia fish products had no negative effect on their quality. On the other hand, pH and TBARS values, color quality, and sensory tests were not significantly different (P>0.05). Therefore, the development of the sun-dried tilapia fish products with the alternative ingredients demonstrated the benefit of substitute ingredients on a better health quality which can increase the value of aquatic animal products and decrease the risk factors of disease in human.

2024-06-15T13:56:10+07:00

The objectives of this research were to study the mortality rate of tilapia (Oreochromis niloticus) and water quality in glass aquariums using extracts from leaves, stems, and roots of Linostoma pauciflorum. There were 4-control set treatments, i.e. no Linostorna pauciflorum, with leaves, with stems, and with roots at a concentration of 6 mg/l. The experiment was conducted in the glass aquarium containing 14 liters of water. Each glass aquarium contained 10 fish with the length between 5 and 7.5 cm. In the experiment, it was found that at the period of 6 hours, the root of Linostoma. pauciflorum had the highest cumulative mortality rate with an average of 100%. Leaves and stems had the highest mortality rate of tilapia at 24 hours with an average of 23.33 and 43.33% respectively while in the experimental set without Linostoma pauciflorum, no dead tilapia was found throughout the experimental period. The water quality in the glass aquarium was at the average dissolved oxygen in the range of 7.19-7.28 mg/l with the average water temperature in the range of 27.50-28.90 degrees Celsius and the average pH in the range of 7.35-7.61.
