The objective of this research was to isolate plant growth promoting rhizobacteria from Wedelia trilobata (L.) A.S. Hitchcock rhizosphere and preliminarily test their plant growth promoting properties such as nitrogen fixation siderophore production phosphate solubilization and indole-3-acetic acid production. Forty-seven bacterial isolates were obtained including 26 isolates of gram positive 18 isolates of gram negative and 3 isolates of actinobacteria. After that 8 isolates (including BWTM1_MSU BWTM2_MSU BWTM5_MSU BWTM6_MSU BWWM6_MSU BWWM8_MSU BWWM9_MSU and BWWM16_MSU) were selected for studying on root colonization and plant growth promoting properties under aseptic condition. The results showed that BWTM5_MSU had the evident on the promotion of plant growth with the most percentage of rice seed germination (63.33%) high level of root and shoot length with 6.11 cm and 3.89 cm respectively. As a result the root and shoot fresh weight was as high as 9.56 mg and 11.33 mg respectively. It also correlated with the highest production of indole-3-acetic acid up to 421.29 ug/ml. The root colonization was studied by counting rhizobacteria isolate BWTM5_MSU from rice rhizoplane and rhizosphere with presented bacterial number at 9.67x106 CFU/g root and 1.64x10 10 CFU/g soil respectively.

This research was aimed to study melting behavior of paraffin wax and to evaluate the natural heat convection coefficient of solid cylinder paraffin wax. Two grades of solid paraffin wax; white commercial grade and yellow market grade were studied. Three sizes of flat test tube in diameter 1.5 2.0 and 2.5 centimeters were used. Three different amounts of paraffin indicated from samples’ heights of 5 7 and 10 centimeters were set. The results found the average melting point of both grade paraffin ranged from 44-77 oC. Based on the numerical analysis heat behavior of solid cylinder paraffin at the initial temperature of 50 oC to room temperature of about 30 oC found that natural convection coefficients was ranged from 3 to 9 W/m 2oC. Melting point temperature was found mass independent property while natural convection coefficient declined as the sample’s diameter size inclined

Changes in muscle protein proteolysis and lipid oxidation of ‘Mu Som’ added with different white and black glutinous rice ratios (w:w) at 100:0 (W100) 75:25 (W75B25) 50:50 (W50B50) 25:75 (W25B75) and 0:100 (B100) during 72 h fermentation at 30°C were investigated. During 36 h fermentation B100 exhibited a higher rate of fermentation than others as indicated by lowered pH and lactic acid production (p<0.05). Due to higher acid production rate the proteolysis of muscle proteins as evidenced by the increase in trichloroacetic acid (TCA)-soluble peptides and smaller molecular weight of proteins appeared as electrophoresis were more pronounced. These might contributed to higher released water and expressible water as well as pale color. Higher black glutinous tice higher released water and expressible water were observed. The lipid oxidation in all samples was observed during fermentation. All samples had no difference in likeness scores of all attributes (p>0.05). From the results the ratio of white and black glutinous rice might contribute to proteolysis which effected on released water of Mu Som.

The purposed of this research “Personal factors and marketing mix that affecting to decision making for choosing nursing home of senior people” was to study (1) decision making behavior of senior people for choosing nursing home (2) personal factors that affecting to decision making for choosing nursing home of senior people. The samples of this study were 400 of senior people who live in Bangkok and provinces nearby. The questionnaires were implemented as the tool for data collection. The statistics methods were used for analyzing data; Percentage Mean Standard Deviation T-Test and One-way ANOVA. The results were found that: Most of samples are women marriages age 60-65 years old finished primary schools retirees revenue between 10000 - 20000 baht. They want to stay at their own home and need helpers when they get older and can’t help themselves. They believe they can support their housing expenditure in between 2000 – 10000 baht. They like making merit being independent and simple life. Their opinions about marketing mix; (1) Product they concern about security system in accordance with intentional standard. (2) Price they prefer offering several price level. (3) Place nursing home should located nearby hospitals. (4) Promotion they concern about clear information and housing tour. (5) People or Employee nursing home should have doctors nurses and specialists. (6)

The study on relationship between lifestyle patterns and event marketing models of the elderly’s activity in Bangkok was aimed to explore the lifestyle patterns of the elderly marketing model of the elderly and the relationship between the lifestyle and the marketing model of the elderly’ activity in Bangkok Metropolis. The statistics used in the data analysis were descriptive statistics including mean percentage and Standard deviation Inferential statistics and multiple regression analysis. The research tool used to collect data was a questionnaire applied on a group of sample consisting of 200 people selected through non - probability sampling in Lak Si Thung Song Hong District Bangkok. Results of the study regarding personal factors of the elderly revealed that most of them were married males aged 60-70 years old without bachelors degrees earning average monthly income 5000-10000 baht mainly from their work savings and currently unemployed. The results of the study of the elderly’s lifestyles of the sample group showed that they mostly participated in social activities exercises hobbies and tourism activities respectively. The results of the event marketing model of the elderly also revealed that the sample needed marketing mix and most activities were to be more personal. Moreover the promotion should be made on the location marketing process cost and activities respectively. The hypothesis testing revealed that the lifestyles social activities and tourism activities were related to the event marketing of the elderly in Bangkok.
