The purposes of this research are to study: 1) understanding of water and electricity saving 2) water and electricity consumption behavior 3) to compare water and electricity consumption behavior classified by personal characteristics of the students Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon. This research was descriptive research. The sample group was specified to be 325 people by stratified sampling. The reliability of this questionnaire is 0.87. Statistics used was descriptive and inferential statistics. The research result revealed that: 1) The overall of understanding and knowledge regarding electricity saving of the students is in the moderate level. 2) The overall of water and electricity consumption behavior of the students is in the moderate level. 3) The comparison of behavior of water and electricity consumption specified according to personal characteristics could be summarized that the students in different genders classes and majors had identical water consumption behavior and the students in different genders and classes had identical electricity consumption behavior. On the other hand the students having different majors had statistically different electricity consumption behavior at 0.05.

Presently the rail transit system plays a major role in the commercial world that they currently use diesel engine not only causing to a lot of fuel consumption but also generating numerously pollution. Therefore this project aims to study the break-even point of investment under comparison of brake specific fuel consumption and pollution of locomotive engines. By experimental works there are 3 types of locomotive engine: Pielstick M.T.U. and Caterpillar which are the difference of the combustion chamber and the fuel injection systems. The simulation load on the static tests (Dynamometer) was used following the regulation characteristic curve which is standard of State Railway of Thailand. As a result of testing the engine using common rail type of fuel injection system M.T.U. was the lowest brake specific fuel consumption at all of engine by the average of all engine speed 206 g/kW-h of brake specific fuel consumption. It is lower than Caterpillar (Semi common rail with direct injection) which is 314 g/kW-h equivalent 34.39 % while Pielstick engine a mechanism fuel injection system is 389 g/kW-h equivalent 47.04 % For pollution area there are Hydrocarbon (HC) Nitrogen Oxide (NOX) and black smut. The engine with direct injection system relieved the previous substance less than the pre-combustion engine. Moreover the compound of carbon monoxide (CO) was found that the pre-combustion engine (Pielstick) discharged carbon monoxide (CO) less than the direct injection engine (Caterpillar) whereas the common rail engine emancipated same substan cenear by with the pre-combustion engine (Pielstick). However the new technology of the engines is high maintenance costs. Therefore a number of applications have to be needed to make a quantitative value for the investment.

This research for study behavior of Thai Boxer about consumer behavior study the way to control body and study the quantity of energy in Thai’s boxer by their meal. The target is Thai’s boxer in Huaykwang district Bangkok. There are 36 persons from 2 campuses LUKBANYAI GYM 18 Persons THAIKIETPETCH GYM 18 Persons. The researcher uses Descriptive Research for record there are two ways to keep the result: questionnaire and keep the schedule of their meal. The researchers summarize percentage standard deviation Pearson Correlation Paired Samples Test with standard 0.05 The boxers have consumer behavior low from the base 66.7 upper percentage 33.3 percentages via spread nutrition: Carbohydrate there are include low cholesterol and protein which have upper nutrition from the base of athlete’s nutrition. The result shows good behavior such as eating 5 group and homemade food are 3.01 Bad behavior such as eating protein for health: Glucose eggs boiled 1-4 eggs per day are normal 2.04 The consumer behavior of boxer before fighting concern with hyper nutrition at least if compare boxer’s need with nutrition it shows 0.05 percentages.

The objectives of this research are; 1) To study the food consumption behavior of metabolic syndrome risk group PhaiNgam Health Promotion Hospital Khok Sung District Sakaeo Province; 2) To study variables affecting food consumption behavior of metabolic syndrome risk group; 3) Propose alteration food consumption behavior of metabolicsyndrome risk group to executive of PhaiNgam Health Promotion Hospital. A group of 190 Metabolic syndrome risk group was sample with purposive sampling. Data were gathered through questionnaire. Data analysis used the number percentage mean standard deviation and Chi-square test (𝜒2). The food consumption behavior of the group was at a moderate level good. Variables affecting food consumption behavior. Found that body mass index waistnumber of children monthly income exertion or physical activity affect food consumption behavior of the group at the statistical significance of 0.05. Propose alteration foodcunsumption behavior. 1) Using red orange green 3 feeding model. 2) Establishing the principle of eating to control energy. 3) Collaboration with public health officials group activities centered around the relationship achieved a rong. For to executive ofPhaiNgam Health Promotion Hospital.

This research has four main purposes. The first is to explore food consumption behavior of housewives in Engineering Regiment of Burachat Camp Ratchaburi province. The second the third and the fourth are to study relations between basic individual factors environmental factors and nutritional knowledge and food consumption behaviors respectively. A group of 245 20-59 year-old housewives living in Engineering Regiment of Burachat Camp Ratchaburi was sampled with stratified random sampling approach. Data were gathered through questionnaire and statistically analyzed for percentage mean standard deviation and Pearson Correlation Coefficient. The study found that most respondents were in the age group of 31 and 40 years old (52.65%) with lower than bachelor degree education (72.65%) two children (64.49%) and average monthly income of 8001 to 13000 baht (42.86%). Environmental factors were in medium level (71.43%) and nutritional knowledge were quite good at 34.69%. Finally overall food consumption behavior was in medium level at 49.80%. According to the results of correlations between basic individual factors environmental factors and nutritional knowledge and food consumption behaviors it was found that environmental factors had significant relations to food consumption behavior (p<0.05).
