This research aims to evaluate the effectiveness and limitations of the Road Safety Audit in Thailand. The evaluations would be used as a guideline to set Road Safety Audit policy for transport authorities in order to enhance the traffic safety in the construction area. In the study the construction project route 318 Trat-Had Lek part2 (Section1) Sta.1+900.00 to 20+000.00 (total distance of 18.100 kilometer) was selected as a case study. The accident statistics occurred before the construction and during the construction were compared to analyze the effectiveness of the Road Safety Audit used in the project. The result of the study shows that the main cause of the accident are traffic management traffic sign and marking as well as pavement surface. Therefore the researchers have provided some recommendations against the accident causes. Finally the operations of the contractors according to the recommendations were monthly summarized to measure the effectiveness of the recommendations.

The purpose of this research is to study the effect of a safety system provided for external wall plastering activity on productivity by studying a construction of commercial buildings. The safety system composed of (1) stable scaffolding system (2) providing clean and not slip walkways on the scaffold (3) installation of handrails not less than 0.90 meters in height along sides of the scaffold (4) installing safety nets around outside perimeters of the scaffolding (5) indicating working area (6) installing stairs (7) providing protection for people who works below (8) providing tools and equipments for transporting material which are safe and ready for using and (9) providing personal protective equipment for workers. Cost of the safety system is 79665 baht for a wall area of 1510 m2 or approximately 53 baht/m2. The prevention cost is quite high because it is an initial investment cost. However contractors could repeat theirs used on future projects. Productivity rates for prior and after the used of safety system are 1.16 and 1.13 m2/person/hr respectively. The productivity declines for approximately 3%. In addition our study found an impact of predecessor activity which is a brick laying activity. If brick walls are not well aligned and plumbed the working time for wall plastering could take longer for 8%. Meanwhile the wall plastering productivity could decrease for 11% and labor cost could increase for 12%.

The research regarding effect of nanotechnology use in making chef apparel on safety of food had the objectives to study about the result of using nano materials coating on yarn and fabric; to study about the use of nano materials which are suitable for fabric to be sewn for being chef apparel and to study the effect of using of nanotechnology for chef apparel on smell and the inhibition of pathogenic bacteria growth using three types of nano materials including Zinc oxide nano Silver nano and Titanium dioxide nano to be coated on four samples including cotton thread T/R thread cotton fabric and T/R fabric. The researcher tested the fabric sample for inhibiting growth of pathogenic bacteria and found that Zinc oxide nano and Silver nano were not different in inhibiting growth of pathogenic bacteria. But the coating on the fabric is more convenient and cheaper. And effective against Gram-positive bacteria. A bacterium that is often found in personal hygiene unclean conditions better than or equal to SS.S3%. Then Four kinds of fabric were sewn to be chef apparel. Actual chef tried wearing to test effectiveness in resisting bacteria. When the apparel was used for two times it was found that T/R fabric which was coated with Zinc oxide nano and Silver nano had different ability to resist gram-positive bacteria and gram-negative bacteria. Fabric T/R Silver nano coating remains effective against bacteria as well and proper to be sewn as chef apparel.

The surveillance and reports on accidents for the current traffic management are carried out by viewing and inspecting CCTV footage. This method is slow to detect incidents and requires a lot of manpower. Since nowadays communication technology and social media play a role in reporting such incidents this research has been conducted to investigate accidents of interest from text messages reported on social media in Thai. There is currently no research or platform that supports this type of work clearly. This research presented the development of a neuron network memory-learning model to solve the problem of incidence pattern classification and incidence severity identification from social media messages in Thai. Using deep learning models such as MLP CNN Bi-LSTM and LSTM+CNN the study was designed and divided into three experimental patterns. This included examining patterns to identify traffic incidents that may be reported as general news or traffic reporting; examining patterns to indicate the type of incidents such as traffic accidents disasters damaged roads or others other than those mentioned; and examining patterns to specify the severity levels of the incidents such as normal intermediate traffic lane blocking or immovable. The experiments demonstrated the capability of CNN+LSTM learning models with the best incidence detection result at 93.44 %. The CNN model gave the best result in identifying a pattern of incidence at 85.29 % and the LSTM model was best able to determine the severity levels of the incidence at 88.53 %.

This research is Study and design The Tourist Service Center and Rest the bikes and bike lane to develop Thai –Yuan culture tourist . Case study of culture Street. Ampor Sawhai. Province Saraburi. Study of the potential of case area to enhancing the area for tourism development of the area to increase even more. And design a tourist service center building. Rest the bikes path and Lane Bikes Breakpoint. To accommodate and service the ecotourism and Tai-Yuan culture in the area Study and design The tourist service center and rest the bikes and bike lane to develop Thai–Yuan culture tourist. Case study of culture street. Ampor Sawhai. Province Saraburi. Field data collection from down to the area. Using tools such as interview questionnaires in the interview area.Conclusion Building design Tourist center Bicycle break The researcher drew the pattern. The uniqueness of the Tai-Yuan architecture. Applied in the design. To be suitable and the shape of the modern era. Structures and materials are easy to construct and consisten t with the use of functional areas of buildings. access the building and the activity area. By landscaping that creates a shade with space. In the field of product design furniture field tested furniture before production. To test the strength which is at the level that passed the test criteria. The map design. Design has pulled the pattern. The uniqueness of the elements of Tai-Yuan is applied in the design in accordance with the building. In the design of bike lane layout. By designing the bike trails along the Tai-Yuan cultural lane line there are major breakpoints such as the intersection the floating market and the old community in the area. Presentation by analysis with aerial maps and identifying key points. For a design that covers the entire reachable area. The bike lanes offer a conceptual design that emphasizes safety and comfort and creates a good atmosphere for cycling.
