Comparative Thermometery in Paediatric Age Group: Is the Non-Touch Infrared Thermometer (NTIT) Reading Comparable to Regular Mercury-in-Glass Thermometer (MIGT) Reading?

Background: Accurate temperature measurement is a critical step in evaluating health or disease especially in children and immmunocompromised subjects;inaccurate measurement may lead to improper diagnosis, wrong treatment or inappropriate intervention. Several methods of temperature measurements exist and comparing these gives room for choosing a near ideal method in terms of speed, safety and accuracy. The study aimed to compare the forehead non touch infra-red thermometer with the axilllary mercury-in-glass method of temperature measurement in the Paediatric age-group. Methods: Study was given ethical approval as part of a larger study. Four hundred and thirty seven children aged 1 to 24 months were studied at the well-baby/immunizationclinic of the University of Ilorin Teaching Hospital over a 6-months period. Both non-touch infrared and theregular mercury-in-glass thermometers were used to take the body temperatures. Data were analysed with SPSS version 21. Pearson correlation was used to determine the relationship between the two methods of temperature measurements, while Bland-Altman method was used to test for level of agreement between them. Results: The mean age and SD was 5.81 ± 4.04 months. Pearson correlation showed a positive correlation between the axillary mercury-in-glass and forehead non-touch infra-red thermometry readings (r = 0.281, p < 0.001). Also, Bland-Altman method revealed a good agreement between both methods of thermometry as 96% of the readings were within the limits of agreement. Mean difference was 0.09°C (95% confidence interval 0.05 - 0.13). Conclusion: Axillary mercury-in-glass thermometer and forehead non touch infra-red thermometers have a good agreement and can be used interchangeably.

A Study on the Optimal Offset Distance Between a Welding Torch and the Infrared Thermometers

Detection of weld defects using real-time monitoring and controlling algorithm is of the significant task in manufacturing industries due to the increased production and liability costs that result when weld defects are not identified early in the production cycle.Monitoring and controlling for robotic arc welding process employed should be reliable,flexible and cost-effective in non-clean,high-volume production environments.Also,the robotic welding system has been utilized a complex jigging and mechanical devices to move the workpiece which related to the stationary welding head for getting higher efficiency and lower costs.To develop the fully robotic welding system,people make use of their senses of sound and/or sight to collect welding information,and take the necessary corrective measurements to ensure the weld quality after processing is satisfactory.Therefore,it is really required that the monitoring and controlling algorithm of sensors for increasing effectiveness in the robotic welding process has been developed.In this paper,bead-on-plate welding using an infrared thermography in the robotic GMA(Gas Metal Arc)welding process has been performed to study the effects of welding parameters on thermal profile characteristics and find the optimal offset distance which applied for monitoring and controlling of welding quality such as bead height.The analysis for correlation between temperature distributions at three offset distance and bead height which based on the regression analysis such as Standard Error of Estimate(SEE),the coefficient of correlation(R)and coefficient of determination(R2)and(Predictive Ability of Model)has been done.The infra-red sensor is useful for monitoring the isotherm radii that arise during the robotic welding process and identifying bead height as welding quality.

Objective: Infrared Tympanic Thermometer(ITT) is one of the most useful instruments for accurately measuring temperature. The effects of ear pathologies on ITT measurement remain unclear. The purpose of this study is to determine if tympanic membrane perforation(TMP) affects ITT measurements in adult patients.Material and methods: A total of 90 adult patients with monaural central TMP were enrolled in this study.Patients were categorized into three subgroups according to perforation size(1-3 mm, 4-7 mm, and 8-10 mm).The tympanic temperatures of the affected and unaffected sites, and subgroups were compared with each other.Results: This study contained 54(60%) males and 36(40%) females ranging from 20 to 58 years of age(mean age: 30.74 ± 9.61 years). The mean tympanic temperature of the side affected with TMP was 36.34 oC ± 0.61 oC.The mean tympanic temperature of the unaffected side with healthy and intact tympanic membrane was 36.33 oC ± 0.6 oC. The Pearson correlation score for the tympanic temperatures and the size of TMP was 0.22 which was not significant(r=-0.12).Conclusion: TMP and perforation size do not affect ITT measurements in adult patients.
