This research aimed to study the design and development to assist in bringing the car seat into the production process and the risk assessment approach to ergonomics to suit operator. Emphasizing the importance of work and trying to create design tools. Organize work appropriately in accordance with the competency and performance of each individual. Using the principles of biomechanics analysis applied in the analysis along with an assessment of the risks by taking into consideration upon 3 factors. 1. The level of severity. 2. The level of frequency.3. Safety measures at the different parts of the body due to which the body must be borne from the outside and in the work. By bringing knowledge of mechanics the proportion of the body anatomy and physiology is able to create the relationship in a model way of Ergonomics which occurs according to the gesture. The use of tools lifting heavy parts and labor pull push and press researchers found in the process of lifting car seat weighs 14.5 kg dimensions width 45 cm length 55 cm and 100 cm in height is the distance of the car seat to shelve. Assembly point distance of 200 cm research has fixed this issue by adjusting the distance of the car seat and shelves by only 50 cm distance can be reduced down to 150 cm and adjust the position of the lifting cushion to reduce twisting torso while assess the biomechanics model of the behavior of all employee in improvement on quality both before and after work station.

Research presents the design and construction of a prototype device alert to clean the solar panels. The measure monitoring of dust and blocking dirt surface of solar panel causes generation Energy low efficiency the devices are alerted to clean solar panel to ensure generation Energy highest efficiency and reduce the cost of solar cell cleaning which will be done 12 times a year. Researchers have introduced electrical and electronic technology with solar panels to provide a reference. Take an installed prototype in process with solar panel energy factory. After that clean the panel referred to the morning every day. This prototype will be processing performance comparison between the solar panels reference with the solar panels factory every day and results via the Internet and record the data in memory. The results of this research found that. Efficiency of electricity production is down 9% as 3 months and 10.47% of the year due to impurities. Dust cover doing have been cleaned twice the efficiency of the electricity production has remained high. This will alert you that washing does not have to be done 12 times as practiced in a solar farm reducing costs 10 times a year.

The study on factors affecting the performance of Thai Tridymite Limited employees was aimed to investigate their personal factors incentive factors teamwork behavior work performance motivation affecting the work efficiency and behavior factors that affected the employees’ performance. The population used in this study was 113 employees. The data analysis relied on the statistics including percentage average and standard deviation. The hypothesis testing applied multiple regression analysis (Multiple Regression Analysis) at the 0.05 significance level. The results showed that the employees working at Thai Tridymite Limited were mostly female between the ages of 30-40 years old with a bachelors degree earning 10000 - 20000 Baht income in the average. They had been working for the company for lower than five years and had high-level motivation concerning job responsibility work success work progress acceptability salary income management interpersonal relationship administration policy work conditions and work security. As a whole the level teamwork behavioral factors was high including the team mission and goals work assignments according to the delegation of duties open communication distributed leadership and the joint decision. In terms of work performance the level of personal performance and organization performance was considered high. The hypothesis testing revealed factors motivating the work performance and teamwork behavior that affected the performance of the employees at the .0 5 level statistical significance. The incentive factors affecting performance included the nature of work work progress salary income work conditions and work security. Teamwork behavioral factors affected distributed leadership and joint decision.

The objectives of this research were to study the personal and investment factors affecting decision making for investing in the provident funds of employees at Conference Solution Company Limiteds and its Subsidiaries’ Staffs. The population consisted of 191 staffs from Conference Solution Company Limiteds and Subsidiaries. The research instrument was a questionnaire with using the descriptive statistics Confirmatory Factor Analysis (CFA) and Binary Logistic Regression Analysis to test the hypotheses. The results of the study found that Education Income per month work the risk of investment knowledge of fund and the economy influencing the decision making to select to invest in the provident fund of the Conference Solution Company Limiteds and Subsidiaries.’ staffs at the statistically 0.05 Significant level.
