The purpose of the study on Knowledge and Understanding of Personal Income Tax Planning is to study the knowledge and understanding on personal income tax problems and obstacles of individual taxpayers regarding internet tax filing. The study compared the level of knowledge understanding and planning of personal income tax of the sample with different demographic factors. The questionnaire was used as a tool to collect data. A total of 410 samples were used for one-way analysis of variance (One Way ANOVA) and compared by Least-Significant Different (LSD). The research found that the overall understanding of personal income tax planning was moderate. The most knowledgeable issues were net income taxable income expenses and tax reduction which were in high level. Secondly the issue of “the personal income tax rate is a progressive tax rate” was in a very high level. The lowest level was “each type of assessment has different deduction rates”. “Type 1 income has the least expense deductible rate” was in moderate level. In conclusion different gender occupation and education levels have statistically significant knowledge and understanding on tax planning.

This research aims to study media exposure and knowledge seeking behavior of mass communication students in Bangkok included problem and obstruction in knowledge seeking. Methodology for the research was mixed method between the qualitative research and quantitative research by used depth interviews with 12 samples and survey research with 420 samples. The results can be concluded as follow: 1. Mass Communication students in Bangkok were social media exposed mostly for follow the news current situation and had conversation about news current situation mostly with friend. But they were trust mostly the information from television. Media exposure on Monday to Friday found that social media exposure was the mostly next were person media and website. On Saturday to Sunday found that social media exposure was the mostly next were television and movie. The least media exposure in everyday was newspaper. 2. Mass Communication students in Bangkok were knowledge seek from various media in the moderate level. They were seek from social media mostly next were electronics and website. How to knowledge seek by study were used tutorials mostly next were online activities and group activities. Problems and obstruction in knowledge seeking were key words data blocking data distortion data analysis and internet signal.

Over the past decade eye-tracking technology can help people all over the world access computers through systems that use gaze control. For people with disabilities this technology is a gateway to communication personal expression and inclusion in society. Eye-tracking technology advance has been transferred to the educational area and now the use of interacting with the multimedia materials and resources in the classroom. The objectives of this research are threefold. The first study presented the development of a low-cost eye-tracking device based on video-oculography. The second study examined various factors in which eye movements can be systematically measured to design appropriate of usability in computer-assisted instruction (CAI). The third study created and determine the efficiency of computer-assisted instruction interactive with eyes lesson on knowledge of ASEAN in elementary education for a student with disabled hand control. This research has looked at three design parameters of the dwell-time click alternative interactive button size and placement of the button which suitable for eye tracking interfaces. The evaluation carried out an experiment to compare performance with five students with a disability. Results showed that a combination of big buttons and short dwell-times are most suited for maximizing accuracy and ease of use. Furthermore the efficiency of computer-assisted instruction is 70.0/71.5 and the user’s satisfaction with CAI were at the high level ( =4.27 S.D. 0.79). Consequently eye tracking technology is a great tool to interaction in computer-assisted instruction for Thai students with a disability. x

This research is the development of the knowledge base on local textiles of northern Thailand by using multimedia for lifelong learning. The aim is to study compile and gather information of local cloths in northern Thailand. Develop a knowledge base by using multimedia on the local textiles of northern Thailand for lifelong learning and transferring knowledge and disseminating the knowledge base on northern Thai fabric by using multimedia for lifelong learning to the community. The research team proceeded to gather primary knowledge from the roots of the researchers who are interested in the local woven fabric. Therefore proceeding further knowledge in the upper reaches from literature reviews Including from field trips for data collection through in-depth interviews with important people Interviewing people who have knowledge about social context community local weaving characteristics weaving characteristics name of pattern type of fabric weaving technique of local textiles in northern Thailand in 9 provinces as well as studying primary data from textbooks textbooks and technical documents and in the internet. Thus the research shown that into 3 parts which are 1. Ethnic groups of Northern Thailand 2. Local woven fabric in northern Thailand and 3. Woven process and pattern. After that the knowledge library was developed by using multimedia on the local textiles of Northern Thailand for lifelong learning. This research can summarize the results in the form of a written description showing that the northern region of Thailand in the past was the Lanna Kingdom area. In the area of Xishuangbanna Before moving to the north of Thailand including the Tai Lue Tai Kheen Thai people Tai Yai people Meng (Mon) Lua people villages scattered throughout the highlands of the Lanna region such as Karen (Pak Kahen M) Mien (Yao) Hmong (Meo) Akha (Akha) Lahu (Mso) Lisu. In addition there are some groups in the Lanna fringe such as Khmu Labri (Tong Lueang). Each ethnic group has its own unique style especially Common skirt Has the same basis with the resin head the resin body and the resin tip but each part is not woven differently Have different colors Some ethnicities have a section called Lep which is the part that the weaver often weaves to keep the thread as for knowledge transfer. The research created a book Local woven cloth consists of videos from local knowledge sources and digital documents and to make the transfer of knowledge more complete Therefore held a forum and exhibition on the topic primary fabric of Lanna Kingdom as a medium for those interested in Local woven fabrics in the Lanna Kingdom of Thailand attended. Exchange ideas from various sources of knowledge from the research. While also receiving multimedia for lifelong learning from the inquiry regarding the satisfaction of the participants. The Keynote speakers are interesting and event condition caused the interest in the knowledge content that used to organize the exhibition. Overall the work is most satisfied.

The research project on The potential of Siphonodon celastrineus Griff traditional medicinal plants of Thailand for treatment from local wisdom knowledge lead to the development of sustainable use with the objective of studying the botanical phytochemical and biological activity of the Siphonodon celastrineus to create confidence in the use of S. celastrineus in herbal medicine by using the bark leaves and fruit of the S. celastrineus to extract with 3 types of solvents. Each of hexane ethyl acetate and methanol respectively from low to high polarity. All nine extracts will be extracted. Preliminary examinations for phytochemistry Antioxidant activity by DPPH radical scavenging assay and quantitative determination of phenolic compounds by Folin-Ciocalteu method and antimicrobial activity were tested. The research found that. 1. The extract of the results of the methanol layer of the S.celastrineus shows a reduction in the amount of 11-diphenol-2-picrylhydrazyl (DPPH) had the highest EC50 equal to 31 mg/ml. The amount of phenol compounds found that the extracts from the methanol extract of S. celastrineus contain the amount of phenol. The highest concentration of 95.23 mg GAE / g dw 2. Extract from the bark of the S. celastrineus with methanol showed the best inhibition of the growth of Vibrio paraheamolyticus with the MIC value of 15.60 mg/ml. The extracts of the S. celastrineus leaf extracts with hexane showed the best inhibition of the growth of Vibrio cholerae with the MIC value equal to 31.25 mg/ml and leaf extracts with ethyl acetate showed the best inhibitory effect on the growth of Vibrio cholerae with a MIC value of 31.25 mg/ml and the extract of the fruit with ethyl acetate to inhibit the growth of Vibrio paraheamolyticus most with MIC equal to 15.60 mg/ml.
