Remote Desktop is one of the most popular method to access to the microsoft windows server which locate as Co-location in the Internet Data Center. But there is still a security problem because a password can be hacked by Trojan infected PC or password can be sniffed via network or even taking a random for password from Password Generator program. This paper presents the completed security protection even the password has been hacked or stolen the hacker can not access to the server via the remote desktop. Normally the port 3389 of Remote Desktop will be closed thus any computer from the internet cannot be accessed. To get access permission it must be done with special requisition with the other password which access through the port 80 (port of web server) that is always generally opened. Only single IP address can get the permission at the time. This method of protection was never published anywhere yet. Result of using this method in the most popular mobile web in Thailand for more than 2 years there is no one can hack into the system at all.

This research is aimed to study the circumstances of the program management of Applied Thai for foreigners in accordance with the views of the executives the lecturers and the students; the employers’ preferences to student performances; the problems relating to the program management as well as to recommend the development approach on the program management of Applied Thai. The target group includes the executives the lecturers of Applied Thai the third and the fourth class students in the academic year 2011. The tool is the questionnaire data analysis using SPSS. The statistics used include the frequency percentage mean and the standard deviation. The results of the study are the overall views of the students the executives the lecturers and the students agree with the program management of Applied Thai in a high level. As for the approach on the program management of Applied Thai for foreigners the need and interest analysis of the students and job market needs.

The objective of this research was to compare the effectiveness of water hyacinth and cootail for wastewater treatment by taking water sample from Klong Bangkhen-mai near King Mongkut’s University of Technology North Bangkok. The results showed that there was no diifference on water temperature changes in tanks between two plants. pH of water in coontail tanks was between pH 8.69 to pH 8.91 and pH of water in water hyacinth tanks was slightly increasing between pH 7.71 to pH 8.26. The more amount of coontail added the higher DO would be between 9.18 mg/L to 10.02 mg/L. Moreover COD of water was decreasing according to the amount of cootail addition and more effective than that in water hyacinth tank especially in 150 grams coontail tanks but TS in water hyacinth tanks was much more decreasing than that in coontail tanks. TS was between 21.73 mg/L to 25.91 mg/L. COD was between 45.30 mg/L to 48.34 mg/L.

The research aimed to study the processing of fish tofu from fresh water fish such as Pla Pluang Hin (Neolissochilus stracheyi) Pla Jad (Hypsibarbus malcolmi) and Pla Mum (Scanphiodonichthys acanthopterus) that are usually found in Bo-klue district Nan province. These three fresh water fish tofu were compared with tofu from Threadfin bream (Nemipterus hexodon) that was a commercial raw material of fish tofu. The fish tofus were experimented on 1) physical attributes 2) chemical compositions and 3) sensory preference. The physical attributes of color size amount of air bubble and firmness were studied. The results showed that lightness (L) of tofu from Pla Pluang Hin and Pla Jad was higher than Pla Mum and Threadfin bream. Threadfin bream tofu showed the highest redness (a*). There was not difference in the yellowness (b*) of all fish tofu. The sizes of the air bubbles in four fish tofu products were between 1.3 to 1.6 mm. which was 80% of air bubble amounts found in a square centimeter. The firmness of all fresh water fish tofu was lower than Threadfin bream tofu. The Percentage of moisture ash fat and protein contents were between 74.2 to 75.7 2.1 to 3.2 0.5 to 3.6 and 21.1 to 25.5 percent respectively. The sensory attribute acceptance of three types fresh water fish tofu were not significant to Threadfin bream tofu. The products were accepted at level of moderate to high preference.

The purposes of this research were 1) to construct and evaluate the efficiency of the Computer Assisted Instruction (CAI) on Nuclear Physics class to have 80:80 effectiveness standards. 2) to compare learning achievement between pre-test and post-test scores after using the CAI 3) to study student’s opinion about CAI. Samples were the second year of Science and Technology students of the Rajamangala University of Technology Thanyaburi in 2011 academic year selected by simple random sampling. The first test was done by one-to-one evaluation and the second one by a small group in order to revise the CAI before implementing within the subject. The efficiency of the CAI was evaluated by experts both in content and production technique of the courseware. The results of this research were shown : 1) the CAI on Nuclear Physics contained the effectiveness at 87.00:85.33 which was higher than the standard criterion set (80:80) 2) the comparison between pre-test and post-test was found that the post-test score of students who studies with CAI were significantly higher than the pre-test score at .05 level and 3) the mean score of the student’s opinion about CAI was 4.35 shown that most of them satisfied the CAI on Nuclear Physics at good level.
