The purpose of this research is to study the effect of a safety system provided for wall tile external building activity on productivity. 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 79318 baht for a wall tile area of 385 m2 or approximately 206 baht/m2. Productivity rates for prior and after the used of safety system are 1.91 and 1.85 m2/person/day respectively. The productivity declines for approximately 3 %. In addition our study found an impact of work is a height of Building the wall tile external productivity could decrease for 6 %.

Food is one of the four basic human needs. Now an increase in the amount of restaurant business has affected the household food consumption behaviour; consumers are buying more ready-to-eat food products. The behaviour increases the risks of consuming contaminated food so the cleanliness and the safety of the nourishment should be seriously taken care. Restaurant Development Way for Food Safety A Case Study: Savoey Restaurant Tha Maharaj Branch was aimed to study practice plans associated with applying knowledge on food safety; to survey understanding on food safety practice; to study factors affecting food safety development of Savoey Restaurant Tha Maharaj Branch. The population and sampale of this study comprised totaled 20 employees qualified for specifications set by the researchers. The tools included content analysis and weighted arithmetic mean mean percentage and standard deviation were employed for statistical analysis. The findings indicated there were two workflow operations of Savoey Restaurant Tha Maharaj branch; Service workflow operation Kitchen and bar workflow operation. The inspections of food hygiene standards in 9 aspects were conducted by researchers. The marks were given associated with the criteria of the List of Food and Drug Administration No 840/2545 attached to the Assessment Methods for Inspection Results of Food Manufacturer under the Ministerial Notification that overall mark of each topic must not lower than 50 percent and no serious defects were found. The Savoey Restaurant Tha Maharaj Branch meets the specified criteria in six aspects comprising dining area with air-conditioners (65.46 percent) outdoor dining area and vicinity (56.82 percent) machine utensils and equipment (87.5 percent) maintenance and cleaning (55 percent) wastewater and waste treatment (58.33 percent) cleanliness and convenience of restrooms (62.5 percent). Each topic meets the criteria on general hygiene standard control. Meanwhile the topics required immediate correction were food preparation and cooking area (27.6 percent) followed by personal hygiene (40.83 percent) and quality control of food ice cube and beverage (49.17 percent) respectively. Thus it is concluded that the current problems arising out of inadequate understanding on good practice of food safety since the business owner has never provided trainings on hygiene for their workers.

The purpose of this research is to study the effect of a safety system provided for column reinforcement activity on productivity by studying a construction of buildings in Bangkok. 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 (4) installing stairs and (5) providing personal protective equipment for workers. Cost of the safety system is 40030 baht for a column reinforcement area of 40 numbers. Productivity rates for prior and after the used of safety system are 11.06 and 8.80 kg./person/hr. respectively. The productivity declines for approximately 20.43 % the working time for column reinforcement could take longer for 13.18 % and labor cost could increase for 13.32 %.

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.
