Medical cannabis usage in the United States and Thailand

2025-08-29T08:28:25+07:00

This paper analyzed the evolving regulations and applications of medical cannabis in the United States and Thailand. Cannabis features two primary therapeutic compounds: CBD (Cannabidiol), which is non-psychoactive and helps alleviate anxiety, manage pain, and reduce inflammation; and THC (Tetrahydrocannabinol), known for its psychoactive effects while also relieving chronic pain, promoting relaxation, alleviating nausea, boosting appetite, and reducing muscle spasticity. The legal status of medical cannabis significantly differs across regions. In the U.S., cannabis is classified as a Schedule I controlled substance federally; however, states like California (the first to legalize medical cannabis in 1996) and Colorado (the first to allow recreational use in 2012) have enacted varying regulations, adding complexity to the legal landscape. Contrarily, Thailand has taken a more cautious approach. Following the 2019 amendment of the Narcotics Act, it allows medical cannabis use under stringent oversight from the Ministry of Public Health. The Thai regulatory framework emphasizes control throughout the supply chain, from cultivation to distribution managed by certified medical professionals.

A comparative study of latent fingerprint quality after using different types of hand care products recorded via fingerprint scanner

2025-06-30T08:56:07+07:00

Currently, crime is becoming increasingly severe, making fingerprint evidence at crime scenes crucial for accurate personal identification. Fingerprint technology has advanced from traditional ink methods to digital scanners, offering greater convenience and accuracy. However, external factors such as hand care products may impact fingerprint quality. This study aimed to examine the effects of four hand care products, hand sanitizer, skin care oil, hand lotion, and petroleum jelly as well as the time elapsed after application on the quality of fingerprints recorded using a scanner. Volunteers applied each product and had their fingerprints scanned at different time intervals. The prints were analyzed using the Automated Fingerprint Identification System (AFIS) to assess minutiae. Results showed that neither the type of products nor the time elapsed significantly affected fingerprint quality. Among the products, petroleum jelly provided the clearest fingerprints, followed by hand lotion, hand sanitizer, and skin care oil. All samples consistently showed more than 10 identifiable minutiae points, indicating that high-quality fingerprints can still be obtained using a scanner even after applying hand care products. This confirms the reliability of digital fingerprint scanning for accurate identification, regardless of product use or time since application.

Building vibration control using water tanks

This experimental study aimed to control the vibration of the building by using the mathematical model. The existing building used in this study was a 6- story reinforced concrete building that was designed to withstand the increase in weight not exceeding 40% of the mass of the 6th floor and using the El Centro earthquake acceleration wave with the intensity of 2g (the acceleration of the earth) as the force. The experiments were divided into 3 cases, i.e. water tank with 10%, 20% and 30% in weight compared to the lump mass of the sixth floor of the building. It was found that Case Study 1 could reduce the vibration by 15.22 percent, Case Study 2 could reduce the vibration by 28.21 percent and Case Study 3 could reduce the vibration by 40.95 percent, respectively. The results of the simulation showed that Case Study 1, which could reduce the vibration by 15.22 percent, should be sufficient to reduce the vibration of the building.

A Study on Ergonomic Risk Reduction and Injury Prevention in Crane Rigging Assembly Tasks

2025-07-04T10:27:59+07:00

This research aimed to reduce the risk of work-related injuries among crane operators, specifically those in the rigger position, at the HOW3 Project site in the Map Ta Phut Industrial Estate, Rayong Province. The study applied ergonomic principles and utilized the Rapid Entire Body Assessment (REBA) method to evaluate postural risks during rigging assembly tasks. The findings revealed a significant reduction in average risk levels across three key operational steps, decreasing from a high-risk level (score ≥ 11) to a moderate-risk level (score range 4–7). This improvement followed the implementation of employee training focused on ergonomic working postures and the design and application of a step ladder to adjust the operator’s working height. This intervention effectively minimized overhead reaching and reduced the risk of posture-related injuries. As a result, the incidence of work-related injuries among workers declined, and the implementation of the step platform received the highest level of satisfaction from the participants. This study demonstrated the effectiveness of ergonomic interventions in improving occupational safety and health in crane rigging operations.

Problems and Obstacles to Assist in Pre-autopsy and to Confirm Death by Paramedics: a Case Study of the Emergency Medical Service System in Bangkok

2025-12-30T19:51:22+07:00

This study aimed to examine the problems, obstacles, and professional responsibilities of paramedics involved in assisting with forensic autopsies. This qualitative research employed in-depth interviews with Paramedics working in Bangkok who have operational experiences under the command of the Erawan Center, Medical Services Department, Bangkok Metropolitan Administration. Ten paramedics participated in the study. Data collection was done during September – October 2027. The findings revealed several challenges faced by Paramedics at death scenes, including difficulties in dealing with bereaved relatives or colleagues who were unable to cope with the loss, inconsistencies between relatives’ statements and the operational team’s findings, and delays or inadequate scene control by police officers. Regarding their role in assisting forensic autopsies, 80% of paramedics agreed with the idea of paramedic involvement in autopsy assistance, while 20% disagreed. Further studies are recommended to explore and clarify the roles and responsibilities of paramedics in assisting with forensic autopsy procedures in the future.
