This research work aims to analyse of metals in thai tradition medicines using Inductively Coupled Plasma–Optical Emission Spectrometry (ICP-OES). The sample groups were divided into four catagories which were Snuff balsam gentian violet and drug pickled liquor. Six metals Aluminium (Al) Cadmium (Cd) Chromium (Cr) Copper (Cu) Magnesium (Mn) and Lead (Pb) were studied. In Snuff the amount of Al was in the range of ND-0.017 ppm the amount of Cd was in the range of ND-0.017 ppm the amount of Cr was in the range of 0.041-0.173 ppm the amount of Cu was in the range of ND-0.244 ppm Moreover Mn content was in the range of 0.633-2.384 ppm. In the case of balsam the amount of Al was in the range of 0-0.575 ppm the amount of Cd was in the range of ND-0.004 ppm the amount of Cr was in the range of 0.025-0.570 ppm the amount of Mn was in the range of 0.460-0.754 ppm whilst none of Cu and Pb was detected. In the case of gentian violet the amount of Cr was in the range of 0.033-0.063 ppm the amount of Mn was in the range of 0.165-0.543 ppm whilst none of Al Cd Cu and Pb was detected. In the case of medicine pickled the amount of Cr was in the range of ND-0.058 ppm the amount of Mn was in the range of ND-0.264 ppm the amount of Ni was in the range of 0-0.034 ppm no metals Al Cd Cu and Pb was observed. The detected metals in thai tradition medicines have the contamination value under the optimization scale for consumable under WHO. It show that some metals were retained in thai tradition medicines and the contamination level of metals in were acceptable.

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 aim of this research was to studied on the optimization of adding the extracted anthocyanin from black non-glutinous rice bran for prolonging shelf-life of Chinese sausage. The study was done by adding the anthocyanin extracts of 2 and 3 % with the combination of sodium nitrite 0 and 1 % during the processing of Chinese sausage. The sensory attributes evaluated using a nine-point hedonic scale and by using ranking test. The physicochemical analysis of storage study was conducted for 4 weeks. All analysis were carried out in every weeks. The results showed that Chinese sausage with added anthocyanin extracts of 3 % with the combination of sodium chloride 2 % gave the lowest value of moisture content with significantly difference (p<0.05). Chinese sausage with added sodium nitrite 1 % with the combination of the anthocyanin extracts of 3 % gave the highest score of overall acceptability. The product can retard oxidation with the value of TBA lower than the control sample with significantly difference (p<0.05)

The purposes of this research were 1) Study behavior and demand of consumers for handicraft product from palm leaf. 2) Design and development handicraft product from palm Leaf. 3) Study of consumer satisfaction for handicraft product from palm Leaf. The results found that. the community of housewife at Tambon Takaok choose artificial flowers and bag. Demand of the buyer in Tall vase flower arrangements Image of Buddha decorate with flower spherical vase flower arrangements and corsages handbag purse and cosmetic bag. Pass the tested to Thai Community Product Standard.The result of customer satisfaction showed that the average highest satisfaction product was spherical vase flower arrangements corsages and tall vase flower arrangements. The average high satisfaction product was Image of Buddha decorate with flowercosmetic bagpurse and handbag .

The purposes of the study were to study the need competency and to develop the competency in information and communications technologies of teachers. The samples were 363 teachers of Rajamangala University of Technology Isan and 70 trainees of experimental group. There were 4 stages of methodology: 1) Study the basic information in order to analyze the need 2) Study the competency of ICT to analyze 3 parts of competency which were knowledge skills and features needed 3) Development preparation and 4) Training course development. The Tools were the questionnaire the achievement assessments of pre and post trainings and the evaluation of the training. The results revealed as follows: The need in information and communication technologies of teachers in 9 aspects was at the high level. The teachers training achievement is significantly different at the level of 0.05. After training the achievement is higher than before regarding the training course expectation teachers are satisfied with this workshop training at the high level. For the suggestion it should be follow-up continuously after training.
