The objectives of this research are to analysis design and develop the Management Information System to Community Products of Tambon Rahaeng Lat Lum Kaew Pathum Thani. Also to install test and evaluate the system. To develop the System Development Life Cycle (SDLC) method is used. To develop and implement PHP script language and MySQL database management system are used. And the system is installed on the Internet Server. To evaluate the satisfaction the 2 groups are the samples the first is the group of 5 operation users and the second is the groups of 40 general users. Convenience sampling is used for sampling method. Gathered and analyzed the data by statistical processing program for Windows software. The result of research show that the satisfaction of the first group (5 operation users) about input screen a data entry is in a good level (x=4.00). About working process and reporting of the system is in a good level (x=4.15) the satisfaction of the group is a good level (x=4.08). The satisfaction of the group (40 general users) the results appear in the same level to the satisfaction of the first group in every case (x=4.21). So the research results can be concluded that all samples are highly satisfied with this information system. And this system can be installed in real working and suit the user requirement.

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.

Objectives of this study were to design and develop seamless womens wear using pattern techniques and to study customers satisfaction of seamless womens wear using pattern techniques. The researcher designed 5 categories of womens wear coat blouse dress skirt and pants. Proper designs for sewing prototypes were selected by experts. These were made from three types of fabrics light medium and heavy. Customers satisfaction survey was made from 385 women working in private companies in Bang Rak Bang Kapi and Pathum Wan Districts of Bangkok. Accidental sampling of participants were asked to answer questionnaires. Data was analyzed by using packaged computer program. Statistics used were frequencies percentages means and standard deviations. The results showed that the majority of samples were aged between 26-30 years educational levels were bachelors degrees monthly income was between 15001-25000 Bahts never bought or used seamless womens wear consideration in buying was by preference bought every month at prices between 501-1000 Bahts per item. The overall customers satisfaction to seamless womens wear was at a very satisfied level at the mean of 4.12.

This research is aimed to establish the small wireless sensor network under the real environment. The objectives this research is aimed to study the data transmission and evaluate the data transmission performance of RPL protocol in wireless sensor network. Four nodes of wireless sensor network have been installation and transmissions between nodes in single-hop and multi-hop have been simulation for testing and analyzing data from the network following the transmission performance index. The research found that the number of hop and building environment are the principle factor to the performance of RPL protocol this might be the major limit to implement the RPL protocol in wireless sensor network

This paper presents about the defrosting time of evaporator in refrigerator by using the temperature different between evaporator and chilling area. This temperature different concept could control the defrosting system to operate according to the load. It also helps controlling the operation of fan motor to be able to operate in accordance with the defrosting time. In general system the timer is set at the highest humidity season which cause the unneccessary defrosting cycle even in low humidity season. This general system create the west of power usage colling system. These can cause time-consuming in defrosting process in the low humidity season and cause the unnecessary usage of power to cooling system. This research is to develop the controller for the defrosting system at evaporator from the investigation. As the results we have found that the defrosting system at evaporator according to its load made the refrigerator can decrease the power about 8% when comparing to constant time evaporator system
