The objectives of this research had to study and compare the problem and obstacle of freshmen student who had studying achievements lower than 2.00 in 3 aspects: the student teaching and studying environment aspect variable classified by sex and major. The research group was the freshman students of the Faculty of Science and Fisheries Technology Rajamangala University of Technology Srivijaya Trang Campus and their studying achievement lower than 2.00. Interviewing was used the research material. The results showed as following: Problems and obstacles which had the most effected to the research group was the student espect for example basic knowledge living adjustment of student lack of motivation and enthusiasm to learn as well as teaching and studying aspect for example lecturer’s inadequate teaching methods respectively. Comparison between problem and obstacle of freshmen student who having studying achievements lower than 2.00 classified by sex and major was found that the different of sex had no statistical significant difference in all and each aspects. In addition the different of student’s major had no statistical significant difference in all aspect. Contrast to in each aspect the studying environment aspect was found statistical significant difference at the level of .05.

The purposes of this research were: 1) to develop Web-Based Instruction (WBI) on “Kingdom of Ayutthaya and Kingdom of Thonburi”กusing student team achievement division technique; 2) to evaluate if the WBI meets an 80/80 efficiency criterion; 3) to compare the students’ learning achievements by pre-test and post-test; and 4) to examine student satisfaction towards the WBI. The sampling group selected by purposive sampling was 25 primary education (grade 5) students in the second semester of academic year 2012 at Wattrithosathep school in Phra Nakhon district Bangkok. The research instruments consisted of two unit of WBI; a learning achievement test administered before and after the learning; and the evaluation form of the student performance. The statistical tests employed to verify the efficiency of the WBI were the E1/E2 efficiency index and t-test. The research result revealed that the efficiency of the developed web-based instruction (WBI) was 84.00/82.80 which was higher than standard criterion 80/80 and comparative of student’s achievement it was found that the student achieved learning progress significantly level of .05. Finally it was found that the learners opinion after using the developed web-based instruction (WBI) was very satisfactory.

This research aims to study the process of puffed Job’s Tears in order to decrease its frying process so that Job’s Tears could be aerated by cooking in a microwave oven. The optimum processing conditions for producing puffed Job’s Tears include soaking them for 22 hours at ambient temperature followed by steaming them at pressure 15 lb/in2 for 20 minutes. Finally the Job’s Tears was dried in the tray dryer at 60 oc for 3 hours 15 minutes to decrease the moisture content to 11-13 %. The Job’s Tears containing 10 grams in weight was by far the best quality when cooked in a microwave oven at 800 watts for 1 minute 30 seconds. The puffed Job’s Tears snack contained 3.27 % moisture 13.32 % protein 14.63 % fat 67.93 % carbohydrate 0.85 % ash and 1.95 % fiber.

The objective of this study was to evaluate the phenotypic lactation curve of crossbred dairy cows raised in Phetchaburi and Prachuap Khiri Khan Provinces. Monthly sampling of daily milk yield of 5516 records from 485 first lactating heifers collected by the Biotechnology in Livestock Production Division Department of Livestock Development during the year 1997 to 2003 were used in this study. Monthly sampling of daily milk yield were fitted using Wilmink function (yt=a+bt+cexp-0.05t) to describe the whole and individual curves and estimated lactation parameters (a b and c). All parameters were used to calculate milk yield at day 60 (MY60) 280 (MY280) peak yield (PM) and accumulated 305 days yield (MY305). The results showed that the fixed effects of herd-year-season of calving level of HF blood or genetic provinces and age of calving were significant differences of all traits (P<0.05; a b c MY60 MY280 PM และ MY305). The phenotypic correlations between the considering traits were significant differences (P<0.05). Moreover the study on the nature of lactation curve could describe the lactating abilities and it could represent the others important traits in lactation curve. Therefore these results could guide the farmers to manage their farm and feeding the cattle to be more effective.

The purposes of this research were to study and explore the relationship between the attitudes toward the preservation of banana-leaf crafts flower works and decoration of fresh flowers of the Faculty of Home Economics Technology students Rajamangala University of Technology and individuals as well as internal and external factors. Research samples were 270 undergraduate students of the Faculty of Home Economics Technology from Rajamangala University of Technology Phra Nakhon Rajamangala University of Technology Krung Thep and Rajamangala University of Technology Thanyaburi. The samples were selected by using stratified sampling. The research methods were questionnaires and testing forms. Data analysis was performed by descriptive statistics and inferential statistics. The results of the study revealed that the attitudes toward the preservation of banana-leaf crafts flower works and decoration of fresh flowers of the Faculty of Home Economics Technology students Rajamangala Univers
