Communication Behavior on Facebook of Students at Rajamangala University of Technology Phra NaKhon
This research aims to study about usage behavior of Facebook users their expectations uses and gratifications as well as the relation between expectations uses and gratifications of Facebook users and communication behavior found among students at Rajamangala University of Technology Phra Nakhon who are Facebook users. The research is conducted using survey as a research method and the data used in this research is taken from a sampling group of 400 students. The results of the study were as followed : 1. The students at Rajamangala University of Technology Phra Nakhon although are different by gender age year of studies faculty GPA and family’s income share the same kind of behavior when using Facebook. 2. The students at Rajamangala University of Technology Phra Nakhon who are different in gender age year of studies faculty GPA and family’s income share the same kind of expectation when using Facebook. 3. The students at Rajamangala University of Technology Phra Nakhon whose family incomes are varied also have different uses of Facebook. 4. The students at Rajamangala University of Technology Phra Nakhon who are different in gender age year of studies faculty GPA and family’s income do not have any difference in their gratification while using Facebook. 5. The expectation uses gratification of Facebook users have positive relation at high level with communication on Facebook. Moreover the outcome has shown that the majority of the students at Rajamangala University of Technology Phra Nakhon use Facebook on a daily basis. Their expectation and usage levels are high and moderate respectirely while gratification level is high.

A novel method for measuring total antioxidant capacity and its application to monitoring the antioxidant status in Thai herbs.
A novel and simple method for measuring total antioxidant capacity or T AC in Thai herb extracts has been developed. The principle is based on generating free radical the deep blue Imipramine radical is generated by oxidizing Imipramine by ammonium tetravanadate in acid medium that can be easily scavenged by antioxidant compounds in the sample. Decreasing in the absorption spectrum at 620 nm related with antioxidant capacity was detected by spectrophotometer method in the proposed of practicable and low-cost However improvement of the throughput Flow injection analysis (FIA) was applied. The variables affecting the signal such as pH reagent concentrations linear relationship was optimized. The novel assay is linear up to 2800 mg Trolox equivalent/L its precision value is lower than 1% RSD and these are no interference from NaOH NaCI and N~C03 The method was applied for determination of three extract fractions of G. sootepensis. The results show the different of antioxidant capacity in each fraction with S I has the most TAC following S2 and S3 respectively. Although a good correlation of the present method was observed between two methods DPPH and Follin Ciocalteu reagent Finally the developed method was easy stable inexpensive environmental friendly and automated measures total antioxidant capacity.
