In this research we studied and fabricated a small vacuum coating system which is suitable for small pieces of the samples. It can help us to save in both cost and time for coating materials in each run. The home-built system consists of (1) a two-stage rotary pump used as a roughing and backing pump for a vacuum chamber and (2) a diffusion pump. The ultimate pressure of this diffusion pump is about 10-7 torr. From the result of testing the fabricated vacuum system it is found that the chamber pressure under the atmosphere can get down to 2.2 x 10-2 torr in 6 minutes by the rotary pump. The pressure inside the chamber is continuously lower to achieve 4.5 x 10-5torr in 30 minutes by the diffusion pump. Moreover we did further testing the system by coating pure aluminum (99.999%) on a Si (100) substrate using a resistive heater source made of tungsten with applied voltage and current of about 2.19 V and 110 A respectively. The aluminum surface has been investigated by SEM and AFM.

Gac fruit healthy fruit contains many antioxidants such as beta-carotene lycopene. Traditional process by boil reduces antioxidants. The purpose of this study is to process gac juice mixed passion fruit juice by microwave. The optimum formulation from consumer tests were done with 50 juice preferred consumer show that the average like is 3.90 point (5 point). The study used the 3X2 factorial in CRD with 600 700 and 800 watts and at 45 and 55 sec. Analyzed color amount of beta-carotene lycopene pH and microorganisms showed that 700 watts at 45 sec. gave the highest level of beta-carotene contents at 38.11 ?g/g. The comparison between the gac juice mixed passion fruit juice through boiled process and the gac juice mixed passion fruit juice through microwave process was investigated. The content of beta-carotene and lycopene of juice through microwave process was than 2.43 and 1.59 times respectively.

The objectives of this research were to study the information seeking method and problems of students at Rajamangala University of Technology Srivijaya Trang Campus the Faculty of Science and Fisheries Technology. The population in the study included 185 fourth year students who conducted a term-paper. The questionnaires were used to collect data and Cronbach’s alpha was 0.83. The data were analyzed by descriptive statistics (frequency percentage and standard deviation). The results showed as follows. Students rated that the university library was the Institutional information resource at the highest level. They mainly used the electronic resources. Students preferred to used the information written in Thai most. The modernity of information was mostly between 1-5 years. Students normally searched for the information 3-5 times a week. There were 3 main problems in seeking information: language was their barriers information was not matched with their needs and information resources were insufficient.

The objective of this paper was study guidelines for taxation to promote the use of energy efficient passenger cars. The passenger car taxation of 4 developed countries; namely Japan Germany United Kingdom (UK) and United States (US) were analyzed and compared with Thai taxation. And studied barriers for promote the use of energy efficient passenger cars in Thailand. This survey conducted by using the close-ended questionnaires collecting data from 400 people who used passenger cars in Bangkok. The results found that tax on acquisition in the developed countries were only subjected to sales tax while Thailand’s acquisition tax composed of customs duty excise duty municipal tax and value added tax. The ownership tax rates of passenger cars in Japan Germany and UK were based on different fuel consumption parameters such as cylinder capacity vehicle weight and CO2 emissions which can promote energy efficient cars. On the contrary the ownership tax rate of USA and Thailand reduces with the age of vehicle. Fuel tax was imposed to support the country energy policy. Opinion survey results of barriers for promoting energy efficient passenger cars in Thailand showed that the significant problems were the lack of incentives measures to promote the use of energy efficient cars.

The objective of this research is to study about circumstance of WatTakien Floating Market community for sustainable management and consider factors which affect to its management scheme. The representative samples are 100 people who live in WatTakien Floating Market community 20 entrepreneurs a government staff and a community leader. The devices of this research are questionary and interview. The statistics are Percentage Mean and Standard Deviation (S.D.) The results of this research are: 1. The importance of recent community circumstance :WatTakien Floating Market community is a tourist attraction where is near Bangkok and easy to get to. Moreover it is in the area of WatTakien which is an ancient temple and keep at naturalness. 2. The opinion about external and internal circumstance which affect to management : The strengths of WatTakien Floating Market is good location because it is in the area of WatTakien convenient transportation and having a canal connecting to Chao-Praya River. However it is lack advertisement and substantial management. 3. The opinion about preventing natural disaster (flood) management scheme : Educate community members how to manage floating market effectively and lay down measures to keep naturalness of community. Support advertising floating market continuously and improve and organize parking to adequate the number of tourists. The aim of this research is to study of Wet Takein Floating Market Community for sustainable management. And factor analysis affect to Wet Takein Floating Market management. The sample of this research People who live in Community of Wet Takein Floating Market are 100 person.
