Food and Nutrition. Industrial Product Design Clothing and Textile Home Economics Administration and Home Economics Communication Arts were found less respectively. Further study needed at bachelor degree by the upper secondary school students in Food and Nutrition Food and Nutrition-Food Product Development Industrial Product Design and Information Technology were found respectively. 4. Business enterprises needs in graduates 4.1 Entrepreneurs were mostly managers in service business enterprises. 4.2 Business enterprises needs in diploma graduates in Food and Nutrition was found the most. Business Computer Clothing and Textile Home Economics Administration and Industrial Product Design were found less respectively. Business enterprises needs annually in Food and Nutrition and Home Economics Administration were found the most. 4.3 Business enterprises needs in bachelor graduates were in Hotel Program Food and Nutrition InfoDl1ation Technology and Food and Nutrition-Food Product Development respectively Business enterprises needs annually in Hotel Program Food and Nutrition and General Home Economics were found the most. 4.4 Desirable characteristics of graduates needed by business enterprises were to be academically expert vocationally expert English literacy specialists and computer literacy respectively. Special characteristics of graduates needed were to be responsible honest friendly creative and leadership respectively.

This study were to Analyze and synthesize the action plans for the study leave system of RMUTL. Research procedures include job analysis questionnaire data collection data analysis and operational plan syntheses. Sixty-three research samples are those who have already taken study leave and operating staff. The statistics used in analyzing the data are Chi-square T-test and One-way ANOVA. It is found that the fast service and in accordance with the rule should be improved. There are some people who do not know the rule and information of study leave. Most of the samples express a moderate satisfaction level. The highest satisfaction level is human resource development planning while the process of making contract is the least satisfaction Male shows higher satisfaction than female. The person who already study leave has higher satisfaction than the operating staff. Finally six action plans are outlined based on this study.

Nowadays energy conservation is widely recognized due to fuel crisis. Petroleum is one of the primary energy used in various aspects especially by factories which consume energy at very high rate. Air pollution has been caused for this reason. Lots of industrial sectors have paid attention to this problem and have found out in different ways to manage it. The purpose of this work was to apply compressed air energy which is zero emission energy as an alternative energy instead of fossil energy. This energy was used in a prototype small three-wheeler powered by an impact wrench. The vehicle carried two tanks of 10 liters of air which pressure is 90 bars. The three-wheeler used chains and gears to transmit power to wheels. The gear increased torque ratio of the impact wrench. An air valve was controlled by a sling-controlling lever. On rear wheel hub 3-speed gear was fitted to enable the car move conveniently according to speed of motor and road condition. Test results showed that air car could move with the maximum speed of 21.4 km/hr and the farthest distance of 1917 meters. The longest period of time which the car could move was about 5-6 minutes. The highest torque produced by impact wrench was 2.323 Nm at rotating speed of 3400 rpm. It was also found that between the rotating speed of 2000 and 4000 rpm the impact wrench produced the best performance and this is a good condition to be chosen for further research and development for maximum efficiency.

This paper presents compare results performance between two conventional controllers for bicycle robot. The bicycle speed control system was a highly nonlinear model multivariable and absolutely unstable. It has used for testing various design control techniques for low power. The objectives of this paper had to developed speed control which derived the mechanic model and experiment. Controllers are Proportional-Integral-Derivatives (PID) and on-off dynamic control. The dynamic system which also includes not stable friction effects the linear zed system model is used as a basis for the design to apply to speed. Computer simulation and experiment have been done controller are capable to control output speed wheel control system successfully. The results show PID controller better then on-off dynamic controller.

In this study waste ash was utilized as a pozzolanic material in blended Portland cement in order to reduce negative environmental effects and landfill volume required to dispose of waste ash. The influence of waste ash namely palm oil fuel ash rice husk ash and fly ash on compressive strength and sulfate resistance in mortar were studied and evaluated by some accelerated short–term techniques in sodium sulfate solutions. Ordinary Portland cement (OPC) was partially replaced with ground palm oil fuel ash (POA) ground rice husk ash (RHA) and classified fly ash (FA). Single pozzolan and a blend of equal weight portions of POA RHA and FA were also used. The resistance to sulfate attack of mortar improves substantially with partial replacement of OPC with POA RHA and FA. The use of a blend of equal weight portions of FA and POA or RHA produced mixes with good strength and resistance to sulfate attack. POA RHA and FA have a high potential to be used as a pozzolanic material.
