The direct labor cost of Ban Khwao district was 503600 baht meanwhile direct labor cost of Khon Sawan district was 473250 baht. The production cost of Ban Khwao district was 122610 baht meanwhile the production cost of Khon Sawan district was 121320 baht. The comparison of cost structure of rice cultivation with the activity-based costing method of Chaiyaphum Province showed that total cost of Ban Khwao district was 861605 baht meanwhile total cost of Khon Sawan district was 764970 baht. This implied that total cost of Ban Khwao district was higher than that of Khon Sawan district.

Sample group contained buyers of bakery in Mueang Nonthaburi District Nonthaburi Province numbering 400 buyers. Research tools are questionnaires. Statistics used in analysis of data comprised frequency percentage mean standard deviation and chi-square. The researcher analyzed the statistic information by using computer programs. The research result found that : 1) most consumers were female aged below 20 years education was in Bachelors Degree; most were school students and university students having average income per month for 10001-20000 Baht; 2) behavior of selection to buy bakery of consumers in Mueang Nonthaburi District Nonthaburi Province it was found that most consumers selected to buy bakery from beverage and bakery shop. Type of bakery selected to buy was bread. The reasons to use bakery shop service were that bakery was delicious. Opportunity to select for buying bakery was to consume by themselves. The period for selecting to buy was 15.00-18.00 hours. Expense in buying bakery in average per time for 51-100 Baht.

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 purpose of this research was to investigate the motivation of the personnel working in the Bureau of Supporting Industries Development Department of Industrial Promotion and to study the organizational commitment and the relationship between work motivations. The sample used in this study consisted of 59 personnel in the Bureau of Supporting Industries Development Department of Industrial Promotion. The author used Quantitative Approach by survey method using data collection by questionnaires. The collected data were analyzed by using the parameters: Percentage μ σ and . When analyzing data from the questionnaires it was found that most of respondents data was male. The age range was 51 years and over. They were mostly government officials most of whom had more than 26 years of work experience. Their salary ranged from 15001 to 20000 baht and most of them were motivated by motivation factors in a high level. The motivation for supporting factors was moderate. The respondents organizational commitment variables were at a high level. When testing the motivation variables it was found that the variables that positively correlated with organizational commitment were job characteristics job responsibilities career path in Policy and Administration salaries and benefits interpersonal relationship and working environment.

This research project has developed and produced natural fiber-reinforced cement tiles by incorporating natural fibers from para rubber leaves and torpedo grass and mixing them with cement and then compressed into a mold with dimensions of cube was 5 cm x 5 cm x 5 cm. The ratio of fiber and cement were 1:9 2:8 and 3:7 respectively. This study used both types of natural fibers including para rubber leaves and torpedo grass. This research found that torpedo grass mixed with cement in a ratio of 1:9 provided high quality of reinforced cement. The density of this sample was found 2.07 g/cm3. Moreover the dry shrinkage value and water absorption were 0.02% 0.10% respectively. The compressive strength was 64.25 kN or 0.23 MPa. In comparison with the standards of non-load bearing concrete blocks according to TIS 58-2530 the result shown that some experimental data are lower than criteria standard. Furthermore the adhesives (i.e. silica) are very important for the quality of natural fiber-reinforced cement
