The purpose of this research is to study the construction safety system for working at height. The safety system for working at height in this research is predetermined by department of labour protection and welfare and safety and health at work promotion association (Thailand). The safety system composed of (1) safety policy (2) safety organization (3) prevention measure (4) risk analysis (5) training (6) safety inspection (7) accident report and (8) emergency planning. Since they had been used construction safety system for working at height in construction site. They have seen different number reduced from accident on site project. However the cost of construction project would have increases.For example building construction site project would taking more time to finished their project. Such as project A have costs increase 281385 baht Project B have costs increase 263648 baht and Project C have costs increase more 285413 bahtRespectively.

The research investigated the process of transporting raw materials for production and the safety of the meat processing industry to support the ASEAN Economic Community. The study objectives were (1) to study factors that influenced the process of transporting raw materials for production and the safety of the meat processing industry to support the ASEAN Economic Community and (2) to determine the consistency of a causal model influencing the process of transporting raw materials for production and the safety of the meat processing industry to support the ASEAN Economic Community. The variables used in this study were the independent variables the organization environment and the organization resources. The mediator variables were the supply chain cooperation equipment strength food quality and Halal sign. The dependent variable was the process standard of transporting raw materials for production and the safety of the meat processing industry to support the ASEAN Economic Community. The researchers used a mixed method of qualitative and quantitative study. Questionnaires were used to collect empirical data from 510 meat operator samples. The statistical methods used to analyze data were the frequency percentage mean standard deviation and the analysis on the structural equation model. The results revealed that the model was well consistent with the empirical data. The Chi – Square (2) value was 122.231 at the degrees of freedom (df) of 150. The chi - square relative (2/df) was 1.815 with the probability p-value equal to 0.953. The index of harmony (GFI) was equal to 0.980 and the modified harmony index measuring (AGFI) was equal to 0.938. The index measuring the comparative (CFI) was equal to 1.000 and the index root mean square of the section standard (SRMR) was 0.020 and the index error in estimation parameters (RMSEA) was equal to 0.000. Additionally the research results also showed that the organization environment organization resources the mediator variables; the supply chain cooperation equipment strength food quality and Halal sign positively influenced the process standard of transporting raw materials for production and the safety of the meat processing industry to support the ASEAN Economic Community.

Admittedly a disc brake plays an important role in the auto part industry since it concerns directly with safety. Therefore the wide range of disc brake has been designed in order to develop its heat ventilation. Thus this project has designed a back-vented brake disc which is difference the current one (front-vented) and tried to create the test to find out the temperature diffusion of the disc brake with the hope to evaluate the coefficient of the heat convection varied by the temperature changing in both kinds of brakes under the forced heat convection in the steady condition. However the steady heat conduction and radiation value will not be counted because it is insignificant. The JASO C406: 2000 Standard is adopted as a guideline in the test. The outcome coefficient of heat conduction will be used in the simulation via the Finite Element Method (FEM) in order to study the temperature diffusion and heat ventilation of both kinds of brakes at each temperature level. Consequently the experimental work reveals then the heat convection coefficients of both kinds are unidirectional. The heat convection coefficient of the front-vented disc brake is 4.40 % in average higher than that of the back-vented disc brake. From the simulation the front-vented disc brake can ventilate the heat better than the back-vented disc brake at 3.02 % in average. It can be summarized that the front-vented disc brake has more temperature difference than the back-vented disc brake. Hence the front-vented disc brake likely gets more stress from the temperature than the back-vented disc brake and might be damaged during the operation more than the another type. Therefore this is tendency that the back-vented is safer than the front-vented brake disc for usage.

This research aims to investigate the cause of the accident that occurred on public passenger van by in-depth accident investigation method. The Method is a powerful and reliable standards and generally accepted. Researchers conducted a thorough review and collect information about bus accident resulting in the death and injury. The results of the analysis showed that characteristics of majority of the accidents occur only one public passenger van(Single-Vehicle Accident). Factors related to the cause of the accident was is mistakes and shortcomings and the interaction between people and road. However considering the overall error of the defect (the driver) is the most of the accident. The analysis of the cause and severity of the accident was found the Deaths by the number of many loss due to the Burned and Physical shocks . Result in death. And Door of the public passenger van was damaged out of the car to make it slow. And most of the passengers could not escape in time.
