: This research aimed to 1) study the reading behaviors of the undergraduate students of the Faculty of Liberal Arts at Rajamangala University of Technology Phra Nakhon 2) study factors affecting the reading of the undergraduate students of the Faculty of Liberal Arts at Rajamangala University of Technology Phra Nakhon 3) seek ways to promote reading behaviors of the undergraduate students of the Faculty of Liberal Arts at Rajamangala University of Technology Phra Nakhon. To answer the research questions a mixed method was used. For quantitative data the questionnaire approved by the experts was used. The data collected from 210 students of 1st to 4th year by the questionnaire were statistically analyzed by computer for frequency percentage mean and standard deviation. For qualitative data the in-depth individual interviews of ten sampling students and a focus group discussion of six students were conducted. The findings were as follows: 1) the students’ reading behaviors were at a high level. Regarding each aspect it was found that they read from the Internet sources at a high level; 2) the overall reading promoting factors were at a high level. Considering each aspect it was revealed that the design of reading promoting activities was at the highest level. The quality of the reading materials was at a high level; and 3) regarding the reading promoting activities role play was at the highest level. The other two respective activities were the use of quality reading materials from the Internet and a variety of reading activities that enable students’ rotation to participate in all activities. The qualitative research findings indicated that to serve the Thai language reading curriculum the students needed a variety of substantial activities in which they could fully participate and they could perform role play based on plays. Regarding the quality of the materials there should be a variety of the current Internet sources and the contents must be relevant to the curriculum to ensure students’ learning and reading achievement.

: The purpose of this research was to 1) study the profile of physical fitness of the undergraduate students of the Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. 2) study the factors contributing to physical fitness of the undergraduate students of the Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. 3) study the guidelines in building physical fitness of the undergraduate students of the Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. The research focused on the quantitative aspects of sport fitness by using equipment to test physical fitness and the questionnaire to measure the factors contributing to physical fitness and the guideline supporting the physical fitness. The questionnaire approved by the experts was used to collect data from 215 students who had been tested for physical fitness. To answer the research questions the data were statistically analyzed and processed using computer program for frequency percentage mean and standard deviation. The results of the study were as follows: 1) a good level of physical fitness of the undergraduate students was sitting and bending forward. An average level of physical fitness included standing & sitting in 60 seconds per one time long jump and 50 meter run. A low level of physical fitness was a 30-second push-up. 2) the factors contributing to physical fitness of the students included 2.1) interest 2.2) physical readiness 2.3) equipment 2.4) need for exercise and 2.5) sport outfits and 3) the guidelines for supporting physical fitness of the students included 3.1) fast walking 3.2) cycling 3.3) swimming and 3.4) running.

This research was aimed to study the participation behaviors in the electrical energy saving the factors affected to the participation behaviors and the promotion of the participation behaviors in electrical energy saving of the undergraduate students of the Faculty of Science and Technology Rajamangala University of Technology Phra NaKhon. The participants of 150 students from the Faculty of Science and Technology was also performed based on systematic sampling. The questionnaire was used. The statistical evaluation was also analyzed based on the percentage mean and standard deviation. A 85% of participants is male a range of age to be 19-20 years old (62.7%) second academic years by about 37.3% and a 65.3% of participants has been studying in the major of computer science. Knowledge levels in the electrical energy saving of the most participants are high (13.33%) moderate (62%) and low level (24.67%). The four participation behaviors in the electrical energy saving were analyzed including electrical lighting system air conditioner and ventilator system office electrical system and electrical equipment maintenances resulting in very high level with the average mean of 4.25 and standard deviation of .547. First the participation behavior in the electrical equipment maintenance was very high level with 4.31 and S.D.=.870. Second the participation behavior in the office electrical system was to be 4.27 with S.D.=.828. Third the participation behavior in the air conditioner and ventilator system was to be 4.21 with S.D.=.549. Finally the participation behavior in the electrical lighting system was very slow level with 4.21 and S.D.=.672. By comparing the participation behaviors in the electrical energy saving with the different of academic major of students the participation behaviors in the electrical energy saving did not significant different.

The objective of this work was to study the adsorption efficiency of bamboo and its surface modified with manganese oxide for removal of Pb(II) ion. The adsorption of Pb(II) from aqueous solution onto bamboo (BB) and manganese oxide-modified bamboo powder (MnO-BB) was evaluated based on batch experiment. The adsorption efficiency of MnO-BB onto Pb(II) was investigated as a function of the initial pH of 6 equilibrium time of 30 min adsorbent concentration of 5 g/L and initial concentration of Pb(II) solution in the range of 50-500 mg/L. The adsorption isotherms of Langmuir Freundlich and Dubinin-Radushkevich were used to describe the equilibrium isotherm. It is observed that the data from MnO-BB adsorbents fitted well to the Langmuir isotherm. The maximum monolayer adsorption capacities of MnO-NC were estimated as 38.76 mg/g. By comparing with BB the amount of Pb(II) adsorbed onto MnO-BB was more than BB by about 40 times under the optimized adsorption condition. According to Dubinin-Radushkevich isotherm the adsorptive mechanism of Pb(II) onto MnO-BB was chemisorption. The kinetic studies of Pb(II) demonstrated that the adsorption of Pb(II) onto MnO-BB adsorbent followed a pseudo second-order model with a good correlation. The adsorption mechanism was processed via chemical ion exchange between H+ and bonded MnO groups and Pb(II) ions in solution

The study of the development of gluten-free brownies with instant Stevia powder for partially replacing some amounts of sugar aims to (1) develop a brownie recipe by using gluten free flour (2) optimise the amount of the instant Stevia powder in order to replace some amounts of sugar partially within the brownies (3) compare the nutrition facts between conventional brownies and the gluten-free brownies with stevia for replacing some amounts of sugar and (4) investigate the consumer perception on the developed recipe. The result shows that the conventional brownies had a higher overall linking based an 9-Points hedonic scale than those of of the samples substituted with Red brown hom mali rice flour. The conventional brownies which consist of Red brown hom mali rice flour and corn flour with a ratio of 50:50 gain higher than the other recipes with a ratio of 60:40 and 70:30. In addition the result of utilising stevia to replace some amount of sugar shows that a sweet ratio of 25:75 is the most favourable recipe than a ratio of 50:50 and 75:25 (p<0.05) For nutrition facts there was no statistically significant difference between the conventional brownies and the brownie added with instant stevia powder. the brownies added with instant stevia powder contains energy moisture fat protein carbohydrate and ash of 480.89 15.90 30.09 5.70 46.82 and 1.49 respectively. The consumer acceptance test using questionnaire in 100 ordinary consumers the result found that the respondents satisfied the instant stevia powder in order to replace some amounts of sugar partially within the brownies in aspect of the flavor of 62.58 the most and following by in aspect of the benefits for health of 58.09 with acceptance towards product was 100%.
