    Computerized panoramic dental X-ray imaging technology uses information recorded from dental treatment history. Teeth are considered a biometric tool to identify people in cases where their bodies have been severely affected, such as to distinguish victims of disasters and fire accidents. In cases where evidence such as DNA, fingerprints, and iris cannot be examined, gender identification is an important factor in establishing personal identity. Tooth enamel is the strongest material in the human body. Resistant to burns from temperature up to 500 degrees Celsius. And the jawbone is the part that is the strongest and most durable. Including showing high levels of gender differences gender. Additionally, the jawbone is the strongest and most durable part of the human body, exhibiting high levels of gender differences. These characteristics of the teeth form the basis for this research. Using medical technology, panoramic dental X-rays taken from living individuals' dental records can determine gender when compared with post-mortem panoramic dental X-rays used as a database to compare traces of events involving lawsuits. Consequently, this guideline is for verifying personal identity by identifying gender from computerized panoramic dental X-rays. For this reason, this study aims to measuring inter-canine distance and finding the ratio of crown width to root length on computerized panoramic dental X-rays in males and females using the Image J program and analyzing with the GraphPad Prism 8 program. The results showed that the average ratio of crown width to root length was higher in males than in females, and inter-canine distance was greater in males than in females. These results emphasize the critical role of panoramic dental X-rays and image processing in biomedical engineering for accurate gender identification.

    Reducing the disparities in healthcare access is one of the important goals in healthcare services and is significant for national health. However, measuring the complexity of access in truly underserved areas is the critical step in designing and implementing healthcare policy to improve those services and to provide additional support. Even though there are methods and tools for mod-eling healthcare accessibility, the context of data is challenging to interpret at the local level for targeted program implementation due to its complexity. Therefore, the purpose of this study is to de-velop a concise and context-specific methodology for assessing disparities for a remote province in Thailand to assist in the development and expansion of the efficient use of additional mobile health clinics. We applied the geographic information system (GIS) methodology with the travel time-based approach to visualize and analyze the concealed information of spatial data in the finer analysis resolution of the study area, which was located in the border region of the country, Ubon Ratchathani, to identify the regional differences in healthcare allocation. Our results highlight the significantly inadequate level of accessibility to healthcare services in the regions. We found that over 253,000 of the population lived more than half an hour away from a hospital. Moreover, the relationships of the vulnerable residents and underserved regions across the province are under-lined in the study and substantially discussed in terms of expansion of mobile health delivery to embrace the barrier of travel duration to reach healthcare facilities. Accordingly, this research study addresses regional disparities and provides valuable references for governmental authorities and health planners in healthcare strategy design and intervention to minimize the inequalities in healthcare services.

    This study reports the preliminary development to biosensor using electrochemistry for lactate analysis. In this work, PEDOT/PSS modified screen printed carbon was developed as working electrode with lactate dehydrogenase (LDH), the oxidized form of nicotinamide adenine dinucleotide (NAD<sup>+</sup>) and glutaraldehyde. The result shows that the current from working electrode with PEDOT/PSS were higher compared with screen printed carbon electrode. These results were consistent with PEDOT/PSS properties that are conducting polymers and can help for more rapid electron transfer. These favorable characteristics allowed its application to detect normal blood lactate concentration in human beings. ©2012 IEEE.

    At the present, the microbiological infection is one of the most significant issues in the global. The medical laboratory diagnosis, microbiology, is the most popular way to identify a type of microbiology which is infected-source. Moreover, there are a few microbial prognoses to support a medical treatment. It is effectively controlled by antibiotic management such as Disk diffusion antimicrobial susceptibility testing, Kirby Bauer AST. This technique is well-known in all microbiological laboratories. This study was the development of interpreting system for antimicrobial susceptibility testing by the disc diffusion technique with automatically measures and interprets inhibition zone diameter. The operated system has comprised electronic part; optical devices, video capture part, and software which manages and analyses all processes. The technology of this system was uncomplicated, effective cost and potential automated test. The disk detected-process and measured process; pre-process, were operated via image processing steps such as image smoothening, edge detection, template matching. The output of this part was sent to the next sections, data correction, interpretation and report, respectively. © 2011 IEEE.
