This study was aimed to explore opinions of electronic correspondence officials to study their satisfaction level toward electronic correspondence and to investigate effectiveness level of electronic correspondence officials working at Royal Aide-De-Camp Department. The population was 25 officials who worked at electronic correspondence office of Royal Aide-De-Camp Department. The data were collected in January 2015 and analyzed by a computer software program using the frequency distribution percentage distribution mean ( ) and standard deviation( ). The result of the analysis revealed high level of opinions of 25 electronic correspondence officials working at Royal Aide-De-Camp Department that most of the respondents were male noncommissioned officers ranging from 29 to 39 years old with bachelor’s degrees and having two to five years’ experience or more. They were based at military logistics office. Also their satisfaction toward electronic correspondence was relatively high as well as the effectiveness level. As for problems of electronic correspondence male officers were found having more trouble on insufficient number of computers and their frequent deficiencies and slow downloading. The highest scores were from the users’ satisfaction caused by convenient work facilitation and time saving. In terms of effectiveness most respondents thought that the system was computably accurate and complete with the effective users’ verification system backup system data protection and simple and swift computation. Future studies should be done to electronic correspondence performance between different workplaces such as the electronic correspondence of Royal Aide-De-Camp Department and Ministry of Defense Deputy office in order to compare problems opinions and effectiveness of different electronic correspondence offices.

The study of Electronic Marketing Communication Towards Buying Decision Behavior which aims to research the consumer behavior in term of receiving message through electronic marketing communication channels. The research compares several channels of electronic marketing communication that lead to buying decision. The method is information collecting from 400 targeted respondents and data analysis by SPSS statistical program. Respondents selected the following electronic marketing communication which is the best tool for buying motivation respectively: The information search through internet by Search Engine system reason: convenience of use

The purposes of this research were to (1) study the needs of teachers and students in Secondary Education Service Area Office 11 in English instruction using mobile electronic devices (m-Learning) and (2) to develop the model of English language instruction using mobile electronic devices (m-Learning) for Upper Secondary Students in Secondary Educational Service Area Office 11. The samples were 222 teachers and 394 students taken from Secondary Educational Service Area Office 11 using a Taro Yamane’s formula with the significant level of .05. The research procedure was divided into two phases. Phase one was the study of the needs of teachers and students in teaching and learning using mobile electronic devices two sets of questionnaires; one set for teachers and one set for students were used to collect data. A model of English instruction using mobile electronic devices was created in this phase. Phase two was the verification of the developed model by the experts. A verification form was used to collect data. Data were analyzed through mean and standard deviation. The research findings were as follows:

Electronic load is an importance part of power supplies testing system. For non-electronic load type it is required to replace a resister with a new one leading to complicated working procedure. The modern power electronic technology is employ to solve this problem. The electronic load can vary the value following user command. Imported electronic load is costly leading Thailand to have a balance of trade deficit. This article proposes design and implement of an economical cost 30V 1 k DC-Electronic Load controlled by Microcontroller. The tested results can confirm the validity of this proposed electronic load

As the high performance electronic devices are required the better heat dissipation in electronic packaging is necessary. In this work the thermal diffusivity of epoxy-based adhesive used as an underfill material in electronic packaging can be improved by adding nano-sized inorganic fillers. These fillers including aluminum oxide (Al2O3) silicon nitride (Si3N4) and silicon carbide (SiC) were used alone for preparing particulate filled-epoxy adhesive. Furthermore In order to achieve good dispersion of filler in matrix the adhesive’s preparation process was adjusted. The maximum loading of fillers in adhesive were determined by the homogeneity of filler and matrix. In addition to avoid the agglomeration of filler silane coupling agent was treated onto surface of aluminum oxide filler to improve interfacial interaction between filler and epoxy resin. The effects of the filler type and filler’s loading on the thermal diffusivity of adhesive were investigated using Laserflash.
