The purposes of this research were 1) to study the purchasing behavior of readyto- drink coconut juice. 2) To study the marketing factors of ready-to-drink coconut juice of consumers. 3) To study the relationship between personal factors and behavior in purchasing ready-to-drink coconut juice and 4) to study the relationship between marketing factors and purchasing behavior of ready-to-drink coconut juice. This was a quantitative research using questionnaires as a tool to collect data from a sample of 400 people without gender who are 20 years of age or older and live in Bangkok. The statistics used in the data analysis consisted of percentage mean standard deviation and correlation was determined by chi-square statistical test. The results showed that 1) most consumers behaviors had a reason to choose ready-to-drink coconut juice as a healthy drink with a purchase frequency of 1-2 times per week. The amount of purchase per time is at 1 bottle / box / bag which the purchase cost per time is 51- 100 baht and most of them choose to buy products from convenience stores. 2) The overall marketing factors in purchasing ready-to-drink coconut juice of the sample group were at the highest level. When considering the factors by aspect they were found that almost all aspects had the highest level of opinion in terms of price products and distribution channels respectively. Except for marketing promotion it was found that the sample group had a high level of opinion. 3) The relationship between personal factors and behavior in purchasing ready-to-drink coconut juice found that gender was related to the purchase frequency and the cost of each purchase. The education level was related to the reason for the purchase purchase frequency and cost of each purchase. Age occupation and average monthly income were related to all aspects of purchasing behavior which were the reason for purchase frequency of purchase location of purchase quantity of each purchase and cost of each purchase were found to be (P ≤ 0.01) and 4) the relationship between marketing factors and purchasing behavior of ready-to-drink coconut juice found that the overall marketing factors were related to behavior in all aspects which were the reason for purchasing purchase frequency purchase location quantity of each purchase and each purchase cost were found to be statistically (P ≤ 0.05)

This research is intended to be used as a guideline for the study of decision making in choosing a skin aesthetic clinic. The study was conducted from a sample of 400 randomized sets. The instruments used were questionnaires. The data consisted of demographic characteristics including 26.8% males and 73.2% females 53.0% aged between 20-30 years 60.0% bachelors degree holders 37.3% an employee of a private company and 33.5% average monthly income of 20001 - 30000 baht. The results showed that the service marketing mix factors (7Ps) of skin aesthetic clinics including product or service price people or staff physical evidence and processes of service provision positively influent the decision to choose a skin aesthetic clinic. The results showed that the overall decision-making factors in choosing a skin aesthetic clinic service were averaged at 3.85 percent a high level. The highest aspect was the search for information followed by the problem awareness decision making and alternative assessment respectively.

This study was conducted to determine the effects of plant growth regulators on in vitro propagated plantlets and microrhizome inductions of Curcuma comosa Roxb. for an efficient development of plant regeneration. In vitro sprouted shoots (2 cm length) of C. comosa were incised in longitudinal section and subcultured on MS media supplemented with 3 mg/L BA for shoot multiplication and plant regeneration. Subsequently the regenerated plants were transferred to MS medium with various concentrations of plant growth regulators; BA (1 3 5 mg/L) kinetin (1 3 5 mg/L) and TDZ (0.5 1 1.5 mg/L). The result showed that MS medium supplemented with 3 mg/L BA was the most effective in shoot induction with the significantly maximum average number of 2.11 shoot buds per responding explant. Moreover MS medium supplemented with 1 mg/L BA produced the longest average of shoot bud explants (12.99 cm) while the basal MS medium induced the longest average of root multiplication (6.63 cm). Furthermore microrhizome induction was produced under in vitro conditions derived young shoot buds upon transfer to MS medium containing various combinations of 1 3 and 5 mg/L BA and 30 60 and 90 g/L sucrose concentrations. The optimum combination in the induction of significantly highest average length of both stem (18.32 cm) and root (7.52 cm) multiplication was obtained on MS basal medium supplemented with 1 mg/L BA and 30 g/L sucrose for 4 weeks. Although microrhizome formation was not produced by the different amount of BA and sucrose in induction medium starch accumulation was found at the base of the stem explants cultured on MS medium containing 60 and 90 g/L sucrose concentrations. Additionally in vitro propagated C. comosa plantlets through microrhizome induction were grown under greenhouse conditions for 4 weeks and further developed into normal plants resulting in successfully high survival rates of 66 – 100% in the cultivated C. comosa.

This research aims to study the ant repellent effects of the crude ethanolic extracts from 7 herbs; Piper nigrum Linn. Alpinia galanga (L.) Willd Ocimum basilicum L. Cymbopogon citratus Stapf Citrus aurantiifolia (Christm.) Swingle Citrus hystrix DC and Stemona collinsae Craib. Whatman filter paper was dipped with each concentration of the crude ethanolic extracts (0.625 1.25 2.5 and 5 % w/v) and placing the bait on a treated filter paper. The experiments were conducted in the natural. The numbers of weaver ants were recorded at 0 - 30 minutes. From the results the crude ethanolic extracts at 5% w/v of A. galanga was the most effective for repellent the ant (repellent rate; %R = 94.72 ± 2.39) followed with C. citratus (%R = 89.45 ± 3.85) S. collinsae (%R = 82.92 ± 4.47) and P.nigrum (%R = 81.20 ± 5.92). The repellent rates of those crude ethanolic extracts were significantly difference from distilled water which use for the negative control (P < 0.05). The crude ethanolic extract of A. galanga at concentration 5% w/v was prepared as spray cream chalk and powder. At 30 minutes of the observation the ethanolic extracts of A. galanga spray was the best ant repellent effect (%R = 100). The result from questionnaires reveals that a spray preparation was the more satisfaction for the using ant repellent products.

This research analyzes the parameters affecting the penetrating resistance of shells on the armor surface by the finite element method. In this study the results were compared with real bulletproof armor firing tests and finite element simulations. modeling of bulletproof armor using Solid Works program. Creating and simulating armor firing pattern using ANSYS Explicit Dynamic program. damage test is based on National Institute of Justice level 3 standards with material of the ammunition is 7.62 mm tungsten carbide (WC) and speed 847 + 9.1m/s. there are two types of bulletproof armor used in this simulation 1. SKD11 2. Aluminum AL7075. The simulations is into 1 category Simulation of stacked armor plates. The sizes of the armor plates are 6 8 and 10 mm and the angles of firing of bulletproof armor are 0 30 and 45 degrees. result of this simulation armor thickness and firing angle are factors of penetration resistance. when the angle of the projectile is tilted it will cause the projectile to deflect reducing the frictional contact from the impact.
