The purpose of the study on decision making to buy Arowana fish online was to investigate the customers’ purchasing behavior on Arowana fish through online selling channels. This is a survey research study and the tools used in the study were the online surves generated from the review of relevant research papers. The data were analyzed from 311 customers using frequency mean standard deviation K-Mean clustering grouping. The research result revealed that most of the customers were males between 31-40 years old with buying reasons for the beauty of the fish called Malaysian Golden Arowana with the price between 5000 - 10000 baht. According to the study on the factors affecting the decision to buy Arowana fish via the online channel the respondents had a high level of decisionmaking on marketing mix in all aspects including the product physical environment price distribution channel process marketing promotion and person. It was found that male behavior was different from the female in terms of the price to purchase which was less than 5000 baht. It was also found that they were from all ages with the same reasons to buy fish for its beauty. However the fish species purchased and prices varied according to the age range. The respondents who were less than 20 years old bought high back Arowana fish for the price of lower than 5000 baht as well as those from 20 to 30 years old. The customers who were 31 - 40 41-50 51-60 and over 60 years old bought golden Malaysian Arowana on the price ranges from lower than 5000-10000 baht 20000 baht or more 5000 baht and lower and 10000 - 20000 baht respectively. By segmenting customers by means of K-Mean Clustering it was found that in Group 1 the majority were males aged 41- to 50 years old with the reasons to buy for the beauty of golden Malaysian Arowana fish with the price of 5000 - 10000 baht. Group 2 was mainly males 21 - 30 years old with the reasons to buy for the beauty of golden Malaysian Arowana fish with the price of lower than 5000 baht. Group 3 was mainly males who were 21 to 30 years old with the reasons to buy for the beauty of golden Malaysian Arowana fish with the price of less than 5000 baht. The fourth group was all males aged from 31 to 40 years old with the reasons to buy for the beauty of golden Malaysian Arowana fish with the price of 5000 - 10000

The purposes of this study were to investigate the component of information and communication technology (ICT) competency for Thai e-commerce personnel and presents The model of competency development in ICT for Thai e-Commerce personnel. The questionnaire was administered to collect quantitative data from 385 electronic business personnel samples and the in-depth interview method was applied to obtain qualitative data from 10 experts in information and communication technology from public and private sectors. The collected data were analyzed by frequency distribution percentage distribution mean standard deviation and Exploratory Factor Analysis (EFA). The results revealed three components with 47 variables of ICT competency for Thai for Thai e-commerce personnel which can describe the combined variance at 74.979 percent. Of all variables 36 variables are highly necessary to identify the competency to design and develop websites and benefit the ability to develop and improve the website according DBD Verified. Six variables refer to the competency concerning the interpersonal skill and responsibility among the personnel inside or outside the organization. Finally five other variables are responsible for the ability to carefully analyze troubles with caution.

This paper presents the method to reduced electromagnetic interference from electronic drive for LED lamp to achieve the TIS standard No.1955-2551. According to standard it must have been tested for magnetic field compatibility that are included Magnetic Field Emission: ME Conducted Emission: CE and Coupling Decoupling Network: CDN. The 3 LED lamp which defined as Type A B and C were tested. Each lamps has 16 watt electric power and was different electromagnetic interference of electronic drive. After that the reduce electromagnetic interference circuit has been designed for low frequency. This circuit test was based on Conducted Emission test only. The integrated design was preferable to reduces electromagnetic interference for LED lamp drive device type A to the TIS. standard No. 1955-2551. That design circuit was been trialled in LED lamp drive device type B and C in order monitor efficiency of reduce electromagnetic Interference. The results showed that design circuit can reduce electromagnetic interference from LED lamp drive device type A and B to the standard. For LED lamp drive device types C the design circuit can reduce electromagnetic interference but it still has not achieve the standard.

This research had the objectives to 1) study of the achievement in electronic document system for using in Rajamangala University of Technology Phra Nakhon 2) study the factors what they affect to satisfaction for electronic document system in Rajamangala University of technology Phra Nakhon 3) suggestion an improvement plan for these achievement system to develop and improve the relevant systems. The official workers in Rajamangala University of Technology Phra Nakhon were concerned in electric document system as 238 persons. The analytical data were Frequency Percentage Mean Standard Deviation t-test analysis Reliability of questionaires and One Way Analysis of Variance. The results shown as the satisfactions level in efficiency system Information system quality control system and management system were very good. The comparison of 2 samples groups by t-test at 95% confidence as the group who need the hard copy documents and useless documents with t-test at. The results were not different in the efficiency level information technology system and data management. The results more than 2 sample groups were analyzed by ANOVA at 95 % confidence. The result showed the satisfaction in the present position working of the samples as the instructors document official or relevant official and the other official was not different whereas the satisfaction in information technology was different. In addition the satisfaction of electronic document system was not different for the official in general education and management duty.

The purposes of this research was to manufacture Electronics Media on Web and compare achievement between teaching using E-leaning and teaching using conventional techniques on Analysis of the Experimental Results by Using Graphs of Science and Technology Faculty at Rajamangala University of Technology Phra Nakhon.
