The purpose of this research paper is to study the solid waste management to the following 3 lines of BTS Sky train construction projects: blue linered line and violet line.The study was carried out by distributing questionnaires to 22 randomly selected contractors on the site from Sino-Thai Engineering and Construction Plc. CKTC Joint Venture Co. SH-UN Joint Venture Co. and Unique Engineering and Construction Plc. The results of the survey showed that an average quantity of solid waste during the commencement ot the project and reached to x=2.54SD=0.80 during construction period. However the quantity lf solid waste was higher upon the termination of the project X=1.97 SD=0.72. For some managers the problems of solid waste were caused by planning and policy maling such as too much rush work unsuitable material management area and misleading materials planning. The other contributors to the problem were traced from operators material transportation to the site. Workers have a lack ot the expertise to work. Supervisors have a lack of monitoring and supervisory work. Supervisors training on waste management played a vital role in promoting solid waste management(X = 3.44 SD = 0.73).

Continuous and Discontinuous (Stepwise) Variable compression Ratio Engine in one of the most widely acceptable methods in terms of efficiency and performance. Even though this. method was not new. it is still not ready for manufacturing due to many mechanical drawbacks such as heavy weight high inertia force heat accumulation too many component parts vibration leakage of engine oil high energy consumption low precision causes of problems for other part that work together and high cost. Today there are more than 250 patents worldwide the relate to this systim. Thus this paper presents the background of this technology mechanism categories analysis of strength and weakness and summary of highest potential mechanism pattern for line production of new generation engines.

The problem of learning ot the students is the instructor preparation the content or knowiedge transfer is not appropriate for the learning potential of indivedual students. This article presents the implementation of intelligent tutoring systems that is response to the difference between the students and has been applied to the Web-Base Instruction by Combination of Adaptive content which is based on Expert model within the ITS. This is a tools to support the learning of students according to their best potential and make learning more effective.

This research aimed to transfer technology of biogas construction for applying the biogas in household. The villagers were instructed and trained about digester construction for applying the biogas produced from cow and pig manure. The produced biogas was used as alternative fuel for cooking in household to replace LPG. The research operation was separated to 3 phases. the first was preparation and introduction. The second was instruction and practical training. The last was monitoring and project evaluation. The number of participants was 30. The number of biogas digester pilot household was 10. From the project evaluation by using the five-rating scale questionnaire it was found that the evaluation about cognition showed the maximun level (x=4.42 S.D. = 0.84). The second was about location duration and food (X = 4.36 S.D. = 0.75). The lowest was about knowledge application (X= 4.28 S.D. = 0.77). For the project evaluation of success it was found that every biogas digester can be used and the produced biogas can be used to replace LPG about 1.8-2 hrs/a day/a housenold. They can save the expenditure about 180-200 Baht/a month/a household. The biogas digester construction cost was about 3000 Baht/a household. So the payback period was 1.38 years.

The purposes of this study were 1) to study the socially responsible behaviorof the students and 2) to study factors that differentiate student’s socially responsible behavior. Factors included predicted variables personal factors: genderstudent grade educational achievement average monthly income per household student and media exposure towards social responsibility in the students atGovernment Universities in Bangkok Metropolitan. The data were collected through 400 students from seven government universities out of fourteen nationwide in 2012.Data analysis employed frequency percentage mean (x)? and standard deviation (SD.). Statistics used for hypothesis testing included t-Test One-way ANOVA andStepwise multiple regression analysis.
