Deterioration of reinforced concrete deep beam structure caused by chloride is severe andtakes up wide area even though the structure is not exposed to sea water or brackish water. Even the structure which is far from sea water or brackish water is affected by this problem.When the reinforced concreate deep beam structure is affected by chloride steel reinforced inside the structure is corroded resulting in reducing the cross-sectional area of the reinforced steel affecting load capacity deflection and beam failure. If there is no repair or strengthening such capabilities are continuously reduced until it is no longer safe to use the beam. Therefore it is necessary to repair or strengthening the deteriorated structure to be safely used. This research investigated strengthening of deteriorated reinforced concrete deep beam caused by chloride with 4 formats of carbon Fiber sheets to seek guidelines for the most efficient strengthening. The resultshowed that the strengthening by the 4 format of carbon fiber sheet could increase ultimate loadcapability yet could not improve ductility of the deteriorated beam to become close to the beamthat is not deteriorated. The strengthening that could increase the maximum ultimate load capability was the table format strengthening. In addition the strengthening that the carbon fiber making 45 degrees with the length of the beam could best prevent diagonal cracks.

This research aims to study the possibility of steel fibers plastic fiber (polypropylene) fly ash and metakaolin mixed into the concrete. The concrete used in the research of the w / c 0.42 By 0.5 percent in the volume of steel fiber and poly propylene fiber in the amount of 0.25 percent by weight of the concrete. Concrete example of this test consisted of plain concrete(OPC).Concrete mixing materials pozzolan fly ash mixed plastics synthetic fibers of the type poly propylene fiber(FA/PP)concrete mixing materials pozzolan fly ash mixed plastics synthetic fibers of the type steel fibers (FA/ST) concrete mixing materials pozzolan meta kaolin mixed plastics synthetic fibers of kind polypropylene fiber(MK/PP) and concrete mixing materials pozzolan meta kaolin mixed plastics synthetic fibers of the typesteel fibers (MK/ST) by casting a cylindrical sample size 10 x 20 cm. Sample size 10x10x10 cm. cube and sample size 10x10x35 cm. beam. After 28 days and cure water concrete examples to test the strength of the pull compressive strength and flexural strength. And to test the movement of chloride through the concrete with Chloride Migration Test. Then bring the strength of the pull compressive strength flexural strength and the chloride permeability of concrete. Bringing concrete materials pozzolan mixed with synthetic fibers to develop the quality of concrete with improved efficiency and also reduces the porosity of the concrete. And permeability of chloride formed in the concrete (Only in landscape with the sea). The test can tell. Concrete mixing materials pozzolan with synthetic fibers to make a significant impact on the properties of concrete is improved as well. Depending on the type of polyester and the amount of material to pozzolan blended.

The purpose of this study is to investigate the background of the ceremony traditional patterns and procession as well as its important role to the community. Fifteen Nasao villagers were purposively sampled. The research tool is interview scripts of the informants. It was found that the Phi Khon Nam ceremony was one of the local traditions of the people in the Khong River basin which was known as the cultural group of Lanchang Kingdom origin with the belief of paying homage to their ancestors. The festival is held from the first to the third day of the sixth waning moon which lasts three days at Pho-Sri Temple Nasao Chiangkhan District Loei. The Phi Khon Nam plays an important role to the community on gathering lots of people who intend to express their gratitude and pay respect to the spirits of their ancestors who protect them control the well-beings of the villagers evoke the annual rain from the heaven and bless crops. Moreover it is believed that Phi Khon Nam is well-recognized as the heart and soul of the villagers and also the identity of the village well-beings and the unity of the community. In addition the Phi Khon Nam procession is the combination of local tradition and religious activities

This research is designing and construction an apparatus of deflection of fixed end beam under uniformly distribution load. SolidWorks program is used for structure designing and CosmosWorks program is used for strength of structure analysis. Deflection and strain of beam were compared with the result of mathematical model according to function stress principal. Error of mathematical model result does not exceed 10%. Therefore this apparatus can be used as prototype and produced for education purpose.

The purposes of this research were to study and compare behavior knowledge and attitudes towards food consumption based on gender and BMI in order to promote the solutions to reduce overnutrition of students at Chitralada School (Vocational Programme). The subject consists of 143 students who are overnutrition at Chitralada School (Vocational Programme) in Bangkok in academic year 1/2017. The sample group was randomized through stratified. The research instrument was a questionnaire on the solutions to reduce overnutrition of students at Chitralada School (Vocational Programme). The data were analyzed by percentage mean and standard deviation compared by t-test and F-test with statistical significance level of .05. The research outcomes revealed that students at Chitralada School (Vocational Programme) who have over-nutrition had a good Behavior of food consumption not sure attitudes towards food consumption and a good knowledge towards food consumption. Comparing food consumption behavior attitudes toward food consumption and knowledge towards food consumption based on gender and BMI the result was that female students have better knowledge towards food consumption than male students with statistical significance level of .05. Otherwise there is no differentiation. The major opinion in solution regarding reduction of Over Nutrition of Chitralada Vocational School Students suggested that the School should provide knowledge for students by making poster and brochures.
