Reused cooking oil is the oil which is used more than one time and contains less than 25% (by weight) of polar compounds. Degenerative reused cooking oil is the oil which is used more than two times and contains more than 25% (by weight) of polar compounds. Major raw material of fried foods is oil. Therefore usefulness of consumed fried foods depends on the quality of cooking oil. When the oil is heated up while cooking chemical change occurs due to the reactions of hydrolysis oxidation and polymerization. These reactions cause degeneration of the oil i.e. black color rancid smell lower smoke point bubbled increased viscosity and generation of toxic substances called polar compounds. This substance can cause high blood pressure heart disease and coronary artery disease. Furthermore the reused cooking oil also contains polycyclic aromatic hydrocarbons (PAHs) - toxic mutagens which can cause cancer.

One important factor that makes the variations of electric current produced from solar cells (Ipv) is the variability of the weather conditions of the day. The one year experiment from January to December 2012 had been set up. The experiment of the comparison of the weather data satellite images and the different current (Ipv_d) was obtained from daily Ipv. The results illustrated that there were 4 major types of the relationship between the Ipv_d and weather conditions; 1) Low Ipv_d at around 2000 mA with low perturbations would correspond to the clear sky condition. 2) Perturbation of Ipv_d in some periods would correspond to the cloudy condition. 3) High perturbations of Ipv_d for all day long would relate to the rainy – cloudy condition. 4) High Ipv_d at around 4000 mA with low perturbations would relate to the cloudy condition all day long.

The purposes of this research were to examine quality of work life and work performance of teachers in Rajamangala Technology University of technology isan and to compare the quality of work life and work performance of teachers in Rajamangala Technology University of technology isan. Sample for the study consisted of 165 teachers in university. Data were obtained through the use of questionnaires and analyzed using descriptive statistics t-test ANOVA and sheffe. The 0.05 level of significance was chosen for the analysis. Results of this study revealed that all of the aspects of the quality of work life of teachers in were at the moderate level and work performances of teachers were at the high levels. Regarding the comparison of work life quality and work performance of teachers in Rajamangala Technology University of technology isan When classified by highest of Education there was found to be no significant difference at 0.05. The analysis of variance to compare the quality of work life regarding to teachers’ different job experience teacher’s different salary as a whole or individual revealed no significant differences.

The aim of this research was to develop the crispy pineapple formula (pineapple salt all purpose flour and glycerin) by using mixture design. Ingredients factor were all purpose flour (10-15% of pineapple) and glycerin (0-5% of pineapple) to form a pineapple patty before drying at 180 oC for 2 min. The sensory result found that the optimum formula contains of pineapple salt and 15 % all purpose flour was the most like score. Then developed with the factors of the temperature and time used CCD bring analyst the color and the sensory test using a sample of 30. The result found that showed the optimum at 174 oC for 103 sec. Consumer tests were done with 200 pineapple preferred consumer show that the average like is 3.72 point (5 point) with a height acceptable scored (88.0%).

The purpose of this study was to study the history of a cultural architecture resources and environment in the local community.
