Data were collected from 312 middle level managers in Medical Device Business in Thailand by using questionnaires as a research instrument. All of the data were analyzed using Structural Equation Model. The analysis of correlation coefficient model showed that the latent variables significantly related to one other at statistical level of 0.001. The analysis of structural equation model (SEM) revealed that the model was completely compatible with the empirical data and the hypothesis. (GFI = 0.933 CFI = 0.972 RMSEA = 0.078 RMR = 0.018) The findings also showed that transformational leadership significantly affected innovative work behaviors at statistical level of 0.001. Similarly innovative climate significantly affected innovative work behaviors at statistical level of 0.001. Likewise knowledge management system significantly affected innovative work behaviors at statistical level of 0.001.

The objectives of this theses are: 1) to study the attitude motivation marketing mix and the decision to purchase second-hand brand name shoes from Facebook; 2 ) to compare personal factors i.e. gender age occupation education level that affecting decision to purchase second-handed brand name shoes from Facebook and; 3 ) to study factors affecting the decision to purchase second-handed brand name shoes from Facebook using the quantitative research methodology through an online survey tool in order to collect required data from 400 samples who actually purchased second-handed brand name shoes from 4 different Facebook pages. The pages were: 1) Second-handed shoes on Khao Lam Road FB Page 2) Taii Taew 2nd handed FB Page; 3) Shoes-Project FB Page; and 4) Cho Chopping FB Page. The data was analyzed by finding frequency percentage average t-test One-way Analysis of Variance and Enter Multiple Regression Analysis. The key research findings are: 1) Most of purchasers who decide to purchase second-handed shoes via Facebook are 215 males (62.50%) 162 are at aged over 51 years (40.50%) 178 are private business owners/entrepreneurs (44.50%) 214 posed bachelors degree or are currently studying (53%). 2) The study on motivation attitude for purchasing second-handed brand name shoes from Facebook found that respondents recognized cost saving as the most important key decision making factor in purchasing second-handed brand name shoes (x̅ = 4.36); followed by the user-friendly and uncomplicated purchasing process (x̅ = 4.19). 3) The study on motivation for purchasing the second-handed brand name shoes from Facebook found that the respondents recognized the importance of price advantage when comparing to the new brand name product (x̅ = 4.40) seconded by product limitation and availability in general local market (x̅ = 4.29). 4) Overall marketing mix factors of second-handed brand name shoes on Facebook was at high level (x̅ =3.79) in which price factor is at high level (x̅ = 4.32) followed by distribution factor ( x̅ = 4.23) product factor ( x̅ = 4.04) marketing promotion factor and market factor (x̅ = 3.89) respectively. 5) The study decision to purchase second-handed brand name shoes via Facebook found that respondents recognized the “convenience to purchase secondhanded brand name shoes via online channels fast and diverse in payment methods” as the most important factor (x̅ = 4.14) followed by personal preference (x̅ = 4.10). 6) From the hypothesis found that: 6.1) Gender age and education differences differentiated the decision to purchase second-handed brand name shoes from Facebook with a statistical significance at .05 level. 6.2) Attitude motivation and product marketing mix that included distribution sales & promotion affected the decision to purchase second-handed brand names shoes from Facebook with statistical significance at the .05 level.

Music piracy is the copying and distributing of recordings of a piece of music for which the rights owners; composer recording artist or copyright-holding record company did not give consent. In order to understand the situation in Thailand the purpose of this paper is to determine factors affecting the unauthorized buying and downloading of copyrighted music. The research tools employed in this study are a questionnaire to enable statistical analysis from the desired sample of 410 subjects and focus group interview 30 subjects from every region in Thailand. The findings show that subjects are influenced in their decision to unauthorized buying and downloading of copyrighted music because of integrated marketing communication; advertising sale promotion public relations and direct marketing in the neutrul level. However the Chi-Square Test results further show with a level of significance at 0.01 that consumers’ decision with regard to unauthorized buying and downloading of copyrighted music depends on price law social acceptance and religion belief which are confirmed by focus group interview. Hence these are a key factor in influencing consumers to enroll for music piracy in Thailand that the rights owners and the policy makers should consider for to prevent or stop this illegal behaviour.

The purpose of this research were to explore factors affecting success of medium size chain restaurant entrepreneurs and to present the keys success of medium size chain restaurant entrepreneurs. This research was mix methods research. The data of qualitative research were collected by In-depth Interview with two chain restaurant experts one president of the Thai Franchise & License Association three medium size chain restaurant entrepreneurs and six individual medium size chain restaurant customers. The data of quantitative research were collected by the questionnaire to 400 Thai medium size chain restaurant customers. Statistics for data analysis included frequency percentage average standard deviation and exploratory factor analysis (EFA). The results of this search showed that the factors affecting success of the medium size chain restaurant entrepreneurs were as follows 1) The factors affecting success of medium size chain restaurant entrepreneurs in management which included strategic planning good organization structure for chain restaurant clearly and defining the system well trained staff owned style of management and set share value. 2) The factors affecting success of medium size chain restaurant entrepreneurs in how to meet customer needs which included quality of service essential of social responsibility customer satisfaction in food quality right location and attractive promotion.

The objectives of this research are to study the rate of deterioration of tyre friction coefficient and investigate the quality of new and old tyres that are currently in use. A set of the rolling resistance testing was designed and set up to work with the single dynamometer according to speed 80 km/h tire load 4660 N and inflation pressure 30 psi. There were three tire samples new tire one year used tire and two year used tire to find the rolling resistance coefficients. The finding shows that the rolling resistance was inverse variation with tire aging. For instance the new tire (1st sample) had the highest rolling resistance on the other hand the two year used tire (3th sample) had the lowest rolling resistance. Moreover the rolling resistance coefficients were inverses variation with tire aging. Besides the one year used tire had the average of the decreasing rate of the rolling resistance coefficient at 0.03689 N/kN per a week while the two year had the average of the decreasing rate of the rolling resistance coefficient at 0.03671 N/kN per a week. Furthermore the result also revealed that the rolling resistance coefficients nonlinearly decreased comparing to the tire aging.
