The diversity of soil microorganisms in mulberry root rot disease infesting fields was investigated from The Queen Sirikit Sericulture Center at Kanchanaburi Khon Kaen Sisaket and Ubon Ratchathani provinces. Isolation of the soil microorganisms was performed on four media as nutrient agar (NA) potato dextrose agar (PDA) rose bengal agar (RBG) and modified selective fusarium agar (SFA). Twenty-four bacterial isolates were arisen from NA including gram positive endospore forming rod gram negative rod gram positive cocci and Actinomycetes. Similarly 75 isolates of fungi were gained from PDA RBG and SFA and could be defined to be Aspergillus sp. Chaetomium sp. Curvularia sp. Fusarium sp. Penicillium sp. Phytophthora sp. and Rhizopus sp. by their morphological characteristics. Verification of the causal pathogen of mulberry root rot disease could be accomplished using specific primers for F. solani in which a DNA band at approximately 300 bp was revealed.

This research aims to study the need to open Master’s Degree Faculty of Liberal Arts Rajmangala University of Tehnology Phranakorn and to advise the management of Master’s Degree Program. This study applied a mixed method (a quantitative and qualitative research design). Data were collected by questionnaires and interviewed questions from two groups of participants. The first group comes from 300 participants who graduated in Social Science field interested people and Master’s Degree in Faculty of Liberal Arts stakeholders. The other is from 18 participants who are lecturers knowledgeable and skilled people in English Literacy and from Tourism and Hotel Business sectors. It was found that: 1. All participants preferred Independent Studies which study 30 credits in compulsory and elected subjects and 6 credits in independent study subject to Research Program. Participants in Tourism Major credited on in class lecture procedure and preferred single major program while participants in Hotel and English Major chose outside university and international lecturers and integrated subjects program. 2. Participants in Tourism preferred such curriculum structure 12/6 credits of Thesis or IS 21 credits of Compulsory Subject and 3/9 credits of Elected Subject. Participants in Hotel and Tourism Major agreed to have paper examination to enter to the degree rather than other processes and chose twilight course to study however participants in English Major preferred considering candidate experiences and supported to study on the weekends. 3. Participants in Tourism admired the whole course payment while the others preferred scholarship for conducting the research. When asking about advantages of the programs participants from the interview agreed that they are essential in improving work lives. The researchers also found that the number and the qualification of lecturers responsible for each program are not suitable to open the degree. They have to be merged such as Tourism and Hotel.

This research aims (1) to study the added value of the package of leftover concept of the creative economy (2) the concept of packaging designers from residues that can affect the attitude of consumers (3. ) to analyze the development trend of packaging residues. The samples used in research The research sample was divided into two groups. The first sample packaging designers from the establishment of private companies and industrial packaging and printing 20. The samples of two academic staff at the university. And design professionals in the packaging industry and related government agencies. The study concluded that: 1) study the need packaging that require packaging to protect the product from damage. Unique and engaging. 2) to design and develop a packaging structure. Not to damage prevention. Attraction and unique.

This project aims to study an effect of stabilizer on the ground pumpkin forming. There were 4 types of stabilizer used in this study which were carrageenan pectin flour and agar with a ratio of 10 20 and 30 percentage by mass. The physical and chemical properties of the sample such as color texture moisture content and sensory test were compared with a commercial streamed pumpkin. The results showed that the ground pumpkin could be formed using carrageenan and agar but the flour and pectin had no effect on the forming. Therefore the sample of ground pumpkin mixed with agar and carrageenan was further observed by measuring the physical and chemical properties. It was found that the properties of ground pumpkin mixed with 30% w/w of agar were the most similar to the commercial steamed pumpkin. The color of L* a* and b* of the sample were 46.15±1.23 11.42±0.51 and 29.75±2.46 respectively. The sensory test was analyzed by weight quality score the overall acceptance was 62.50%. In conclusion 30% w/w agar was the best stabilizer using in the ground pumpkin forming therefore this result would be used to develop a new product.

The research aimed to analyze and compare contents of accumulated residue of chlorpyrifos chromium lead and cadmium in five varieties of vegetables in Loei River Loei Province. Five varieties of vegetables such as Vegetable fern (Diplazium esculentum Limnocharis flava (L.)) Limnocharis flava (L.) Buch Lasia spinosa (L.) Thwaites swamp cabbge (Ipomoea aquatica Forsk) and water mimosa (Neptunia oleracea Lour.) were collected during winter summer and rainy seasons from Phu Luang Mueang Loei and Chiang Khan District. Chlorpyrifos was analyzed by high performance liquid chromatography (HPLC). The results showed that the highest chlorpyrifos contents were found in vegetables in winter and summer season in the amount of 0.04±0.00 mg/kg. Analysis of all three heavy metals were carried out dry ashing at 500C and acid digestion with nitric acid prior to analyzing by flame atomic absorption spectrophotometry (FAAS). The results showed that cadmium accumulation in the highest content among all metals in water mimosa (Neptunia oleracea Lour.) in summer season from Phu Luang District (1.83±0.01 mg/kg). The second highest metal content was lead which has found in swamp cabbge (Ipomoea aquatica Forsk) in summer from Mueang Loei District (1.40±0.08 mg/kg). chromium showed the lowest content in Limnocharis flava (L.) Buch in winter from Mueang Loei District (0.47±0.04 mg/kg). The contents of chlorpyrifos and heavy metals were not exceed the legal limits set by International Standard Food and Ministry of Republic Health No.98 of Thailand except Ipomoea aquatica Forsk which collected in summer that showed the lead content higher than the legal limits.
