The reserch development of artifitial flowers creative made from Pa-kao-ma cloth consists of two objective. 1) To study satisfaction of the target group. Finding 1. Development process of artifitial flowers made from Pa-kao-ma cloth can be done with asking 5 expertion in to topics. The first topic mass flowers appearance. It can divide to five types. Monochl any dous. Mass flowers was made from litly. Alternative multilamination mass flowers was made from rose. Inflorescence flowers mass flower was made from Gladiolus. Composite flowers was made from hippeastrum johnsonil busy. Come-shaped mass flowers was from calla lily. The sec topic is filler flower. It can divide to two appearance. The First is sam flowers. It was made from Bouqainvillea. The second is orchid. It was made from Cattlega. 2. Satis faction to artificial flowers product from target amount 50 people in three forms following. Flowers vasc is the most satis faction with average equal to 4.89. Flowers frome 3D have average equal to 3.97. Accessories has average equal to 3.70

The aim of this study was to synthesize a non-halogen phosphate based flame retardant by using chitosan and phosphate compound as substances. The P-N synergistic effect was required in this study. After synthesizing the flame retardant was coated on cotton fabric by dipping then the fabric was tested for flame retardant properties compared to untreated cotton fabric. The three products with N and P in structure were gained by synthesis and confirmed by H-NMR spectroscopy. The time of combustion raised from 14 seconds in untreated cotton to 21 seconds in cotton that treated by product No. 2. Next the mechanical properties of treated cotton fabric are going to measure and the variation of techniques to apply flame retardant on fabric surface is going to test.

This research work was to study the improvement of toughness and impact resistance of polylactic acid (PLA) with modified soybean oil (MSBO) and palm fiber (PF). The detail of this work was divided into three parts. The first was to find the suitable condition for modification of soybean oil with ozonolysis. The second and last parts were to study the effects of MSBO and PF contents on the properties of PLA respectively. For oil modification the reaction times were varied from 0 to 3 hours and the chemical changes in molecules of soybean oil were investigated by Nuclear magnetic resonance (NMR) and Fourier transform infrared (FTIR) spectroscopies. The result suggested that the most suitable condition for ozonolysis reaction was 2 hours considering the decrease in double bond between carbon atoms and the increase in hydroxyl group into molecular structure of MSBO. For the effect of MSBO content on mechanical properties it was evaluated by tensile and impact testing. Differential scanning calorimeter (DSC) and scanning electron microscope (SEM) were used for thermal and morphology analyses. The result showed that elongation at break and impact strength of modified PLA by MSBO increased about 89 and 25 % compared to those of neat PLA respectively. MSBO act as the efficient plasticizer for PLA considering the conversion of fracture behavior from brittle to ductile good dispersions of MSBO droplets in PLA and the decrease of glass transition temperature (Tg) with addition of MSBO. The addition of PF improved the impact strength of modified PLA. Strong interfacial bonding between PLA and PF indicated MSBO being both coupling agent for PLA and natural fiber and plasticizer for PLA. For migration test it was found that contents of released heavy metal and migrated chemical from specimens of PLA and PLA/PF composite were under the criteria according to Notification of the Ministry of Public Health (No. 295) B.E. 2548.

The purposes of this research were (1) to study the usage behavior of social media for the purpose of reading or viewing beauty products based on blogger recommendations (2) to study factors of blogger recommendations of beauty products (3) to study the behavior of decision making to purchase beauty products based on blogger recommendations (4) to study personal factors and behavior of decision making to purchase beauty products based on blogger recommendations (5) to study the relation between the usage behavior of social media for the purpose of reading or viewing beauty products based on blogger recommendations and the behavior of decision making to purchase beauty products based on blogger recommendations and (5) to study the relation between factors of blogger recommendations of beauty products. 400 persons were included as a sample. The data was gathered by using questionnaires and being analyzed by methods of calculating frequency percentage average standard deviation one-way ANOVA and multiple regression analysis. The results of the research were as follows; Considering the usage behavior of social media for the purpose of reading or viewing beauty products based on blogger recommendations. It was found that most consumers decide to purchase beauty products because of an interesting product presentation and the facial beauty products are the most purchased products by the consumers. In an overall picture the consumers agree with the factors of blogger recommendations of beauty products at a very good level and the factor of blogger is the most agreed factor.
