This Project presents electric bicycle. The structural feature is the use of the bicycle to be modified as it is designed to spin the rotor of the 5-phase magnetic line generator set and test the voltage distribution. The principle of operation of electric bicycles relies on the mechanical energy gained from cycling. The rotor consists of a series of permanent magnetic poles intersecting with a stator consisting of a set of conductor coils generating an AC voltage and converting it from AC to DC through a diode bridge to obtain DC voltage. To be connected to the boost converter to increase the output side pressure level to get the right voltage to charge a 12 volt battery. batteries. The test has been tested for cycling to generate electricity at a speed of 400 rpm while no-load has a voltage of 23.3 volt and with a load per load and at a speed of 400 rpm the voltage is 12.1 volt If the bicycle is cycled at an increased speed the voltage and current will increase. In order to transmit electric power to the single-phase power system an inverter is used to connect the single-phase power system to transmit to the single-phase power grid.

This research aims to study 1) to develop listening and speaking English students of Rajamangala University of Technology Phra Nakhon provide higher efficiency 2) to compare the achievement of listening. English speaking students of Rajamangala University of Technology Phra Nakhon before and after the experiment 3) to enhance the students self-learning of Rajamangala University of Technology Phra Nakhon using correct sentences to communicate in daily life 4) To produce teaching materials to be used by English language instructors or support staff within the Faculty of Liberal Arts. Rajamangala University of Technology Phra Nakhon in preparation for the ASEAN Community in 2015. Experimental study was conducted by using the selfaccess multimedia computer program to practice listening and speaking English skills. The researcher created 3 lessons to take the test in 8 weeks 3 lessons for 1st year Tourism students in Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. There are 30 students enrolled in English 2 in the second semester of academic year 2013. The instruments used in this study were 1) to practice listening and speaking English skills 2) achievement test listening and speaking English. The data were analyzed by percentage. The results showed that the attitude of the students towards self-access computer multimedia practice in listening and speaking English skills. Overall found the average level of attitudes that influence decision making was good in 87.6%. After using the multimedia computer program students have well 84.71% in listening and the attitude of the students towards computer multimedia speaking was good in 85.23%.

Abstract Milk ice cream is the one of most popular dessert in many countries. But the most milk ice cream contain high amounts of sugar and fat. It is for this reason that consumers who exercise regularly concern about the impact of ice cream consumption on health and have led to a considerable rise in high protein and low sugar ice cream demand for this consumer group. Therefore the objective of this study was to develop the reduced energy milk ice cream by using chicken breast and inulin. Milk ice cream was supplemented with chicken breast at 5 10 and 15% by total weight. The result showed that 10% chicken breast ice cream was highest score of sensory evaluation. Sugar was substituted with inulin at 25 50 and 75% by weight. The result showed that the replacement of sugar with 50% inulin was suitable for ice cream. The chicken breast ice cream with inulin formula were determined the physical properties. The result showed that viscosity overrun texture and melting rate of the developed formula were 147 cps 41% 11780 g force and 6% respectively. The lightness (L*) redness (a*) and yellowness (b*) value were 88.68 4.60 and 19.11 respectively. The proximate compositions moisture and protein content of the chicken breast ice cream with inulin formula were 68.03 and 11.79% higher than basic formula whereas fat and ash content of the chicken breast ice cream with inulin formula were 6.02 and 0.45% lower than basic formula. Microbiological quality of the chicken breast ice cream with inulin formula were in the acceptable limit according to Notification of the Ministry of Public Health. In addition the total energy of the chicken breast ice cream with inulin formula was lower than basic formula. The cost of the chicken breast ice cream with inulin formula was higher than basic formula at 16.23%.

The purposes of this study were 1) to study exercise behavior and media exposures 2) to compare personal factors with exercise behavior and 3) to study the media influences and factors affecting exercise behavior of the elders in Bangkok Metropolis. The data were collected through 450 elders residing in Bangkok Metropolitans. Data analysis employed frequency percentage mean (x)and standard deviation (SD.). Statistics used for hypothesis testing included t-Test Oneway ANOVA and Stepwise multiple regression analysis. The study presented
