This research work was to study the effect of surface treatment of natural fiber and the effects of type and content of natural fiber on the development of acoustic material from natural rubber foam /natural fiber composites. The surface treatment used for this research work was sodium hydroxide (NaOH) treatment. NaOH Concentrations and treatment times were varied from 0 to 15 %wt. and 0 to 30 min respectively. Natural fibers used for this work were bagasse fiber (BF) and oil palm fiber (OPF). The suitable condition for surface treatment was estimated by fiber length and diameter (L/D) ratio and morphology of natural fiber. The result suggested that L/D ratios tended to increase when NaOH concentrations and/or treatment times increased except for NaOH concentration of 15 %wt. L/D ratios of OPF after surface treatment were changed more than those of BF. The suitable conditions of NaOH treatment for BF and OPF were NaOH concentration of 10 %wt. and surface treatment times of 30 and 10 min respectively. The effects of fiber type and content on sound absorption properties of natural rubber foam /natural fiber composites were investigated by cell characteristics sound absorption coefficient DMA analysis and bulk density. Both treated BF and OPF with suitable treatment condition were varied from content of 0.0 to 10.0 %wt. The result showed that the cell size of composites tended to decrease with addition of natural fiber whereas number of foam cell per unit volume increased. After adding natural fiber more than 2.5 %wt. cell size of composite foam and number of foam cell per unit volume tended to change the inverse direction. Natural fiber in composites enhanced the sound absorption efficiency. Sound absorption coefficient of composites adding BF was more than that of composite adding OPF. The addition of natural fiber enhanced the elasticity of composites and that increased sound absorption efficiency. NaOH treatment led to creation of strong interfacial bonding between natural fiber and natural rubber and enhanced the sound absorption efficiency. Density of NR composite foam increased with increasing natural fiber content.

The survey research aimed to: 1) study the levels of self-development needs in preparation to enter AEC; 2) make a comparison of the students’ needs levels in aspects of personal data; and 3) propose appropriate forms of activities to be used in the development. The subject obtained through stratified random sampling consisted of 321 first-fourth year undergraduates of the Faculty of the Home Economic Technology Rajamangala University of Technology Phra Nakhon. The tool was a questionnaire. To analyse data the frequency percentage mean standard deviation t- test and ANOVA were used. The results were as follows: 1) The overall level of self-development needs was high ( X = 3.75). The needs for selfdevelopment in line with the Thai Qualifications Framework for Higher Education were high ( = 3.89). Moreover the level of needs conforming to Thai Graduate Preferable Qualifications for the ASEAN Community was moderate ( X = 3.46). 2) There was no statistically significant difference ( p<0.05) of the self-development needs level when genders educational levels or academic performances were considered 3) As for the activities it was rated best to use training for the development of cognitive skills numerical analysis communication and information technology skills domain of psychomotor skills and knowledge on ASEAN Community rules and regulations; lecturing for knowledge on ASEAN Community rules and regulations; study touring for knowledge development; camping for ethics and moral interpersonal skills responsibility and language skills; and student inter institutional exchanging for neighbouring countries knowledge development.

The study was aimed to investigate the production of banana fiber that was suitable for decorating handicraft basketry examine its effectiveness develop decorative handicraft materials for basketry from fibrous layer on the trunk of the banana tree and promote the obtained knowledge in the community of Plasticseeroong Baanmor Promburi District Singburi Province. The research result could be summarized that the most appropriate production process of dry fibrous layer on the trunk of the banana tree mixed with fibrous layer of paper mulberry was done through mechanical process. After bleaching the mixed fibrous layer was stirred by Hollander beater with the proportion of wet fibrous layer and water at 1:40; 10% of dry of paper mulberry was boiled for three hours in sodium hydroxide at 100 degree Celsius then bleached with 1.5% of hydrogen peroxide with 4% of the dry fibrous layer weight at 90 to 95 degree Celsius for two hours. The mixture of wet fibrous layer on the trunk of the banana tree with wet fibrous layer of paper mulberry was 70:30 which was considered appropriate for decorating handicraft basketry. Concerning the examination of mechanical properties of banana tree fibrous layer according to the standard of TAPPI T it was found that the folding endurance of paper value was 144 (N. m/g); the tensile strength value was 32.16 (N. m/g); the tear resistance value was 26.56 (mN.m2/g); and the bursting strength value was at 1.94 (KPa.m2/g). The fibrous layer obtained from on the trunk of the banana tree was fabricated into decorative basketry materials for example flowers palm leave hats flower key chains bags and paraffin coated flowers for bamboo boxed. The attendants’ satisfaction on the training of the production of decorative handicraft materials of basketry from fibrous layer on the trunk of the banana tree to 30 members of the community of Plasticseeroong Baanmor Promburi District Singburi Province concerning the training service speakers training procedures facilities and training benefits was at high level (90.67%) and at average level (9.33%).

The purposes of the research were to study and investigate the relationship between the role perception in Home Economics profession of students from the Faculty of Home Economics Technology and personal and supporting factors. The personal factor consisted of gender year level academic achievement and department. Supporting factor consisted of knowledge experience in Home Economics profession attitude towards Home Economics profession and students’ participation in professional activities. Researchers used stratified random sampling to obtain a sample population of 318 bachelor’s degree students from the Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon. Research tools were a questionnaire and a test. Data were analyzed by descriptive and inferential statistics. The results were found that the role perception in Home Economics profession of students from the Faculty of Home Economics Technology was at the high level. There was a significant relationship between the role perception in Home Economics profession of students from the Faculty of Home Economics Technology and year level department attitude towards Home Economics profession and students’ participation in professional activities at the 0.05 level. There was not a significant relationship between the role perception in Home Economics profession of students from the Faculty of Home Economics Technology and gender academic achievement and knowledge and experience in Home Economics profession.

This research aimed to study 1) the demand for short-term vocational training courses in home economics 2) create a training curriculum of home economics profession short of demand. Handicrafts Cooperative Occupational Groups Ko Kret Nonthaburi and her 3) the effects of short-term vocational training courses in home economics created The population in this study were selected purposively is a group of professional arts cooperative. Koh Kret Nonthaburi number 30 was used in the questionnaire and short-term training courses in home economics. Data analysis and statistics used were percentage average and standard deviation.
