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.

The effects of plant growth regulators alone or in combination on Hexachlorocyclohexane (HCH) phytotoxicity were studied. Waxy corn seeds were immersed in different plant growth regulators that are 1) 2 mg/l Indolebutyric acid (IBA) 2) 2 mg/l Thidiazuron (TDZ) 3) 2 mg/l Gibberellic acid (GA3) 4) 1 mg/l IBA + 1 mg/l TDZ 5) 1 mg/l TDZ + 1 mg/l GA3 and 6) 1 mg/l IBA + 1 mg/l GA3 then sawn in 30 mg/kg HCH-contaminated soil or non-contaminated soil for 10 days. All plant growth regulators could enhance shoot and root dried weight of waxy corn seedlings in non-contaminated soil. Only 2 mg/l GA3 could enhance root length of waxy corn seedlings in non-contaminated soil. In HCH-contaminated soil only 2 mg/l TDZ could increase shoot dried weight of waxy corn seedlings. Also 2 mg/l IBA or 1 mg/l IBA and1 mg/l GA3 could increase root fresh weight of waxy corn seedlings. The exposure with HCH in soil did not affect to shoot and root tissue even though the growth of shoot and root were inhibited. However the exposure with HCH and receive exogenous plant growth regulator induced aerenchyma formation in cortex and pith of waxy corn root.

Nowadays Eye Tracking Technology is one main challenge for developers of new human-computer interface. This technology provides a more natural way of interacting with a computer system by user’s eye. Now commercially available systems exist; however they are not widely used because of expensiveness. This paper describes a tutorial that shows step by step how to build a low-cost eye tracker using eyeglass setup. The glasses are designed to work with video-oculography technique (VOG) in the infrared spectrum. The key features of the eye is a center of the pupil. The gaze point of users are estimated based on order polynomial regression (linear quadratic and cubic). This research conducted an experiment with 30 participants tested eye-gaze calibration. Consequently the experimental results showed that eye-gaze can be estimated in real-time while the cubic function can be accurate eye-gaze position more than the other function.

The objectives of this research is to study (1) The factor of decision making in Bangkok high school students affected to study in bachelor of Mass Communication (English Program) (2) The factor that is correlated in decision making in Bangkok high school students affected to study in bachelor of Mass Communication (English Program). The sample population consisted of four hundreds high school students in Bangkok. The instrument of research was a questionnaire. The Statistical Package for the Social Sciences (SPSS) for Windows computer program was applied for analyzing formulating and tabulating the data collected. The techniques of descriptive statistics used were percentage mean and standard deviation. Techniques of inferential statistics utilized were t-test one-way analysis of variance (ANOVA) in order to analyze differences between variables taken as a group. If there is a statistically significant differences found between pairs in a group Scheff?’s pair testing were deployed. Multiple Regression Analysis were applied in order to analyze the factors of decision making in Bangkok high school students affected to study in bachelor of Mass Communication (English Program). If there is a statistically significant found in Multiple Regression Coefficient of Correlation under paired testing will be used to identify the correlation between factors. The results were as following: 1. The factors of student program in high school affected the decision making to study in bachelor of Mass Communication (English Program) were high school program. 2. The marketing factor of Mass Communication Technology affected to Bangkok high school students decision making to study in Bachelor of Mass Communication (English Program) is product price place promotion.

To manipulate students data which participate in activity projects of the university. Student activity management information system support working of student development division to know how many students join campus activities in each year. This information can increase efficiency for clubs and staffs to set up proper activities according to student requirement. Each student activities data will be printed in activities transcript report when graduate that help rising employment rate in the future. The system was developed tested and assessed by 5 experts get a good level of satisfaction in whole process. The average result of the assessment is 3.99 and standard deviation is 0.38. In conclusion the system accomplishes in good quality able to enhance management of student activity system effectively.
