The purposes of the study were to investigate 1) Relationship between Quality of Work Life Organizational Commitment and Employee Loyalty 2) Levels of and Employee Loyalty and 3) Compare and Employee Loyalty at Wangtai hotel Suratthani according to their personal factors. The questionnaire was administered to 138 samples selected through convenience sampling and analyzed by the percentage distribution mean standard deviation t-test one – way ANOVA; Pearson Product Moment Correlation Coefficient analysis was set between 0.01 and 0.05 statistical significance. The study results revealed high level of the overall Quality of Work Life and Organizational Commitment as well as the Employee Loyalty which accordingly agreed with each other at 3.75. Moreover in terms of personal factors different ages resulted in different Employee Loyalty behaviors. Additionally the employees’ different marital status led to different affective aspects while salary incomes resulted in different perceptions towards the organizations and affective aspects. Also work experiences resulted in different employee loyalty behaviors at 0.05 statistical significance.

The research on the factors influencing the creation of competitiveness for exporting Halal food using Thailand - ASEAN logistics route was aimed (1) to study the factors that influenced the ability to compete for exporting Halal food using Thailand - ASEAN logistics route including economic environment resources and operational capabilities financial administration legal administration and logistics and (2) to examine the consistency of the causal model with the empirical data. The variables used in this study were the independent variables including the economic organization organization resources financial administration legal administration and logistics. The independent variable was the ability to compete for exporting Halal food using Thailand - ASEAN logistics route. The researchers used a mixed method of qualitative and quantitative study. Questionnaires were used to collect empirical data from 445 exporter samples. The statistical methods used to analyze data were the frequency percentage mean standard deviation and the analysis on the structural equation model. The results revealed that the model was well consistent with the empirical data. The Chi – Square (2) value was 417.295 at the degrees of freedom (df) of 569 with the probability (p-value) equal to 1.000. The chi - square relative (2/df) was 1.368 with the index of harmony (GFI) equal to the probability p-value equal to 0.960. The modified harmony index measuring (AGFI) was equal to 0.930 and the index error in estimation parameters (RMSEA) was equal to 0.015. Moreover it was found that the variables were economic organization organization resources financial administration legal administration logistics and Halal food quality had positive effect on the ability to compete for exporting Halal food using Thailand - ASEAN logistics route. The research results suggested the entrepreneurs focus on environmental variables economic organization organization resources financial administration legal administration logistics and Halal food quality which could lead to advantageous for the competition exporting Halal food using Thailand - ASEAN logistics route.

The objectives of this study were 1) to analyze the capability contributing to the competitive advantage 2) to synthesize the key performance indicator from the internal factors 3) to examine the level of competitive capability and 4) to develop the strategy to enhance the capability of competitive advantage in the faculty of Mass Communication Technology Rajamangala University of Technology Phra Nakhon. The samples used in the study included 71 interviewed stakeholders in the university and 400 survey participants. The findings pointed out as follows: (1) the strategy t enhance the competitive advantage were defined in five aspects: curriculum educational management personnel learning environment and image and alumni association (2) the level of competitive advantage was rated high in the following order: personnel educational management curriculum and image and alumni association. The learning environment was also in high level.

The aim of this work was to study the magnetic properties of magnetic glass-ceramics with composition system SiO2-CaO-Na2O-P2O5-BaO-Fe2O3. The magnetic glass–ceramics were prepared by conventional melting at 1300oC for 2 h of the coprecipitation derived starting products and heat treated at different temperatures. The structure and microstructure of the samples were characterized by X-ray diffraction energy dispersive X-ray analysis (EDXA) and scanning electron microscopy. The magnetic measurement showed that the samples which contained barium ferrite exhibited magnetic behavior which is similar to soft magnetic materials. Finally the samples were soaked in simulated body fluid (SBF) for 14 days. The apatite was found to form on the surface layer of glass-ceramics and it increases with the barium ferrite content was increased.

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.
