การพัฒนาสบู่สำหรับใช้งานแกะสลักแทนผักและผลไม้เพื่อสร้างมูลค่าเพิ่มให้งานหัตถกรรมไทย
The objective of this research was to determine the formulation of soap for carving operations and study the satisfaction of developed carved-soap by carving person. There were 3 basic formulas of the soap e.g. olive oil formula (formula 1; 500 ml olive oil 60 g sodium hydroxide and 140 ml water) coconut oil formula (formula 2; 200 ml coconut oil 34 g sodium hydroxide and 80 ml water) and glycerin formula (formula 3; 200 g glycerin and 5 g sodium hydroxide). The basic formula 3 showed the highest satisfaction scores from carving person when compared with other formulas. The next experiment was to find the optimal temperature for heating the mixtures in the range of 40-60oC. The results showed that the temperature of 45oC was the best treatment for heating three types of soap mixtures. Moreover the formula 3 soap received the highest satisfaction scores ( X = 4.21-4.53) from carving person which had the good appearance exquisite styles shape and proportion right. There was no crack no visible of mold growth and soap powder on the product after caving operations. The satisfaction of 52 carving persons between the general soap and developed carved-soap for carving operations was studied using 5-point rating scales. The satisfaction scores of softness stickiness and aroma were significant different (p<0.05) between two types of soap. However the dryness/hardness silkiness color painting property and overall quality scores were not different. The suitable shape of soap for carving operations was a round shape followed by square shape oval shape and heart shape respectively.
The chemical structures of bioactive compounds of ficus hispida linn
Study the chemical structure of the bioactive compound extracted from the leaves of the Ficus hispida Linn with extraction techniques Sequential Extraction using three organic solvents hexane ethyl acetate and methanol . Phytochemical examination testing antimicrobial activity of crude extracts and fraction of methanol extracts with the four species of microorganisms Vibrio cholerae Staphylococcus aureus ATCC 25923 Streptococcus mutans ATCC 27175 Vibrio paraheamolyticus and to determine the molecular structure of compounds. The results showed that 1. Crude methanol extract of the leaves of the Ficus hispida Linn show inhibitory microbial species more than crude extracts of hexane and ethyl acetate . 2. Testing antimicrobial activity of methanol extracts fraction was found to inhibit microbial highest F5 show. 3. The molecular structure of compounds crystals are colorless mp. 188-195 0C. Research should further study the molecular structure and biological activity of bioactive compounds in other areas including anti-cancer Antimalarial and antioxidant activity of different parts of the study. The roots leaf flower and fruit seeds to plant information for the selection and to further develop research in the next commercial.
ปัจจัยที่มีความสัมพันธ์กับการสำเร็จการศึกษาตามกำหนดเวลาและหลังกำหนดเวลา ของนักศึกษามหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร
The purposes of this research were to study and compare the factors related to the timely or late graduation of students at the Rajamungala University of Technology Phra Nakhon (RMUTP). The sample consist~d of 290 students of the Rajamungala University of Technology Phra Nakhon. The instruments used for collecting data were the 5 rating scales questionnaire. The reliability was 0.87. The data were analyzed by using SPSS for window. The statistics used were a -coefficients frequency percentage average mean t-test and Chi-square. The results were as follows: 1. Students background: The sampling group who timely graduated were mostly female studied in Faculty of Home Economics Technology and enrolled with high school certificate and got grade point average between 2.00-2.99. They were admitted through direct entrance examination. Their hometown was Bangkok and stayed with the parents who were together. The highest academic qualification ofthe parents was primary school. Most of the parents were venders. Their monthly income was over 15000 Baht. The parents were the financial supporters of the sampling group who mostly did not do part time jobs. Their grade point average was between 2.00-2.99. They went to the parents when they had problems. Students characteristic: The sampling group who timely graduated had learning problems about adjusting their learning style and not understanding the content taught. While the sampling group who untimely graduated had problems about health economics heedlessness from family members and learning problem on preparing special project and planning. Both groups had the same opinion toward teachers characteristic that the teachers paid a great attention on teaching. Most of the sampling group who timely. Graduated agreed that the teachers used easy to understand language. The sampling group who untimely graduated agreed that the teachers used the appropriate assessment method. For the opinion toward the learning environment most ofthesampling group who timely graduated agreed on the cleanliness of the registration process and the other group agreed on the sufficiency ofthe library to search for the information. 2. The factors related to the timely or late graduation of students show that sex faculty and grade point average (OPA) are correlated with both timely and late graduation (p< .01)
The development of medicinal plant extracts to control Weed germination and growth
Study on the inhibition of germination and growth of weeds in rice fields. The extract from the leaves of Xy/ocorpus gongeticus Parkins and Porinori onomense Hance using fermentation Maceration and extraction techniques for Sequential Extraction with three types of solvent hexane ethyl acetate and methanol. The resuLts showed that Leaf extract of Xy/ocorpus gongeticus Parkins with ethylacetate at a concentration of 2000 -3000 ppm showed the highest inhibition of germination and growth of weeds. When the substance to be separated by chromatographic techniques showed that the extracts inhibited the germination and growth percentage of Fl is the highest. Leaf extract of Porinori onomense Hance with hexane at a concentration of 2000 3000 ppm showed the highest inhibition of germination and growth of weeds. When the substance to be separated by chromatographic techniques showed that the extracts inhibited the germination and growth percentage of F4 is the highest. Which can be used for research and development of natural products from plants to control weeds in rice fields to develop further research to commercialization
Chemical composition and biological activity of ficus hispida linn
To study the effect biological activity of a fig tree extract using Sequential Extraction and use of fennentation Maceration using solvent 3 types of hexane ethyl acid state and methanol to extract 12 Chanin made. tested oral cancer cells (human mouth carcinoma: KB) lung cancer cells (human small cell lung cancer: NCI-HI87) breast cancer (breast cancer: MCF-7) anti-malarial. (Anti-malaria; Plasmodium falciparum) Microculture Radioisotope Technique used to test anti-tuberculosis (Anti-Mycobacterium. tuberculosis. anti-TB) to the Green fluorescent protein microplate assay (GFPMA). The results showed that extracts of the fig tree has anti-cancer Including breast cancer lung cancer and oral cancer. Extracts of the fig tree does not have anti-tuberculosis and extracts of the fig tree shows some anti-malarial. In further research should study the molecular and biological activity of the fig tree from the roots seeds leaves flowers and fruit to the biological activity ofthe data for a selection of extracts from medicinal plants to make. Purification and further develop research in the next commercial.
