Thailand is on the way toward ASEAN Economic Community or AEC in the year 2015. The AEC aims to create one-solid base for production and distribution and concurrently seek mutual economical profits. A kind of business that may allow Thai entrepreneur to survive more easily in ASEAN is the selling and purchasing of goods and services via internet or ‘E-commerce’. The objective of this research is to study the factors that influence the development of E-commerce that will facilitate Thai entrepreneur when we enter AEC. The samples of our study are the group of E-commerce’s entrepreneurs who legitimately registered with Department of Business Development. Our research revealed that the major factors that influence the development of E-commerce is the knowledge in foreign language which is considered to be the source of major advantage for business with average at 3.9750. Follow by the opening of free trade area which will cause more obstacles in term of the increasing number of competitor with average at 3.8475. The lease is population’s preference that would directly affect business’s revenue with average at 3.7450.

This purpose of the research was to study of Solar Absorber Shape Effect in the Solar Air Heater. These has designed and constructed the solar air heater for drying agricultural products of two different types. Comparison of First thing used square type one glass layer used centrifugal fans to feed air and installed solar absorber which each made of sinusoidal corrugate galvanized steel sheet coated with dull black paint and each other made of trapezoidal corrugate galvanized steel sheet coated with dull black paint. The results of research showed that the solar absorber which each made of trapezoidal corrugate galvanized steel sheet coated with dull black paint is most suitable. Which has overall thermal efficiency 66% and can generate maximum temperature 96.13 degree of Celsius

To determine the impact of breakwater construction on fish assemblages larval and juvenile fishes were used to interpretation. The study was conducted in the inter-tidal zone constructed breakwater and natural sandy habitats of Pakmeng Beach at Sikao District Trang Province. The morphology of water bottom showed that differ between the front areas of breakwater construction and natural beach. The bottom profiles at in front of natural beach is seem to be deep immediately from shore and connect to a flat sand dune whereas in front of breakwater construction area was shallow and flatten. Fish assemblage data had showed the average number of larval and juvenile fishes no differ between the two habitats whereas the number of taxa of juvenile fishes was higher significantly in the inter-tidal zone of breakwater constructed area (Mann-Whitney U=11.5 p=0.017) Even though our study have revealed the application of fish assemblage data to asses the impact of constructed breakwater. Current study have limited on data collection not entire seasonal of larval and juvenile fishes abundance. Using our interpretations in other study sites is necessary to collected more frequency both beach morphological and fish assemblage changes.

This research was to used Lanna wisdom project-based learning activities in sufficiency economy of sustainable development courses for undergraduate students Rajamangala University of Technology Lanna Chiang Mai. The objectives of this research were to development of Lanna wisdom project-based learning activities to study students’ learning achievement about local wisdom and to study students’ satisfaction towards Lanna wisdom project-based learning activities. The instruments were included lesson plans on local wisdom pretest and posttest using Lanna wisdom project-based learning activities tests assessment of students ability to present Lanna wisdom project-based learning activities according to actual conditions and students’ satisfaction towards Lanna wisdom project-based learning activities questionnaires. Research was assigned to students learning activity by Lanna wisdom project-based pretest and posttest using Lanna wisdom project-based learning activities tests evaluated students’ learning achievement and students’ satisfaction towards Lanna wisdom project-based learning activities. The research findings were as follows; 1. Lanna wisdom project-based learning activities was associated knowledge of Lanna wisdom with sufficiency economy for application in daily life 2. Students’ learning achievement about local wisdom in lesson 4 after using Lanna wisdom project-based learning activities are increase at statistically significant level of 0.01 and capable of Lanna wisdom project-based learning activities presentation at a higher level. 3. Student overalls satisfaction towards Lanna wisdom project-based learning activities at the highest level. The recommendation of research that universities should support of appropriate teaching curriculum by project-based learning activities.

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.
