The study objectives of the electrical energy saving behavior of student in faculty of business administration Rajamangala University of Technology Phra Nakhon 1) to study psychological trait factor psychological state factor and situational factor in overall group and subgroup of the students’ electrical energy saving behavior in faculty of business admimistration RMUTP 2) to study the interaction effect between psychological trait factor psychological state factor and situational factors related to the students] electrical energy saving behavior in overall group and subgroup. The sample size was 361 students of bachelor’ s degree. The study factors were 7 independents future orientation and self-control) 1 psychological state factors (appropriate model from family knowledge on the electrical energy saving and the information about electricity saving). The dependent factor was the electrical energy saving behavior. Frequency percentage arithmetic mean and standard deviation were used for descriptive statistic while stepwise multiple regression and two-way ANOVA were used for inferential statistics in overall group and subgroup according to social demographic characteristics. The research findings were as follows : Firstly all 7 factors of psychological trait factors psychological state factor and situational factoe could predict 52% of variance of the electrical energy saving behavior. The most prediction power factors were appropriate model from family positive attitude towards saving behavior receives electricity saving information and well-being respectively. Secondly the interaction effect was found well-being and electricity saving information with the electrical energy saving behavior of student which was male and female group and freshman and sophomore group junior and senior group G.P.A above 3.00 and parents’ income lower than 30000 thb Thirdly the interaction effect was found the future orientation and self-control and knowledge on the electrical energy saving behavior with the group of student who mother has an education lower than undergraduate.

Springback behavior is a major problem of sheet metal forming process. Especially aluminum alloy which often encounter such problems often. At present aluminum alloy is increasingly of used in the automotive industry for replace of the steels due to its lightweight and good finished surface. This work aims study to springback behavior of cold rolled aluminum alloy (AA6016) during air-bending process by ISO7438/2010 test standard. To analyze the influence of bending process parameter are included: sheet thickness punch radius bending angle die open and the ratio of bending radius and material thickness (r/t) effecting to springback behavior. The results are clearly that the springback angle is likely to increase with increase of the punch radius size of die open and the ratio of punch radius and sheet thickness and the springback tenor to decrease when the sheets thickness and bending angle increased. The increased bending angle will resulted to bending surface region is roughness increase and crack occurred to follow. As a result the bending force and the springback angle decreased.

The purposes of the study on service quality influencing behavioral intention of Government Housing Bank users (headquarters) were to explore opinions behavioral intentions and service quality that influenced the Government Housing Bank (Head Office) users’ behavioral intention. The samples used in this study were 222 customers who came to the Government Housing Bank from 9.00 am to 11.00 am and 1.00 pm to 3.30 pm. They were chosen by the systematic sampling method. The statistics used for data analysis were frequency percentage mean and standard deviation. The hypothesis was tested with correlation coefficient (R) and regression analysis at significant level of 0.05. It was found that Government Housing Bank (headquarters) users were mostly females between 31 and 50 years old with bachelor degrees working for the state enterprise and earned the average monthly income over 30000 Baht. The level of the quality service was high revealing the service with attention trustworthiness reliability and intention. Tangible services and behavioral intentions were at a high level including the buying intention word-of-mouth behavior complaint behavior factors on price sensitivity and the service quality which influenced the behavioral intention of the government housing bank (Headquarters) users at the 0.05 level of significance.

The purposes of this study were to study 1) personal factors affecting Rajamangala University of Technology Phra Nakhon (RMUTP) personnel’s happiness at work 2) personal factors affecting the personne’s l work ethics and 3) relationship between the ‘s personnel happiness and ethical behavior at work. 303 samples were selected using the Taro Yamane method. A questionnaire was applied as the instrument used for data collection. Statistics used for social sciences included frequency percentage mean standard deviation t-test and one-way ANOVA. The study indicated that 1. Personal factors were highly related to RMUTP personnel’s happiness at work either in the individual aspect or in the overall. 2. Personal factors were highly related to RMUTP personnel’s work ethics behavior either in the overall or in the individual aspect. 3. Happiness at work was related to RMUTP personnel’s work ethics behavior and resulted in ethical behavior of the university personnel with an average of 65.6%.

The purposes of this research are to investigate 1) personal factors contributing to the longevity of elderly 2) the dietary behavior of long-living elderly and 3) the relationship between personal factors such as:gender age BMI and dietary behavior. The samples are 29 of long-living elderly with ages more than 80 years old living in Tambon Tha Phi Liang Muang district Suphanburi province. The long-living elderly must be able to answer the questions. The statistics used to analyze data in this research are frequency percentage and Chi-Square (χ2). The data were analyzed using statistical tools. As for thier dietary behavior it was found that most long-living elderly usually have five food groups:eggs UHT milk paddy morning glory cabbage watermelon papaya and vegetable oils. They purchased these five groups of food for consumption. Boiling was the main method of cooking. They usually stored food in the refrigerator to keep them fresh. The relationship between personal factors and dietary behavior could be classified into 5 areas : types of food frequency of consumption sources of food methods of cooking and methods of food preservation. The finding found that gender age and BMI were related with food consumption. However cooking (boiling) was not related with statistically significant level at .05.
