The research aimed to: 1. study and compare food and nutrition knowledge of adolescence by looking at gender and level of education. 2. study and compare the awareness of food and nutrition by comparing gender and level of education. 3. study and compare the practice of food and nutrition by comparing gender and level of education. 4. study the relationship between knowledge awareness and practice of food and nutrition of the adolescence in Muang District Prachinburi Province. Tests and questionnaires were used to gather the data from 346 samples. The Stratified Random Sampling was used. The data were analyzed by using percentile mean standard deviation t-test one way analysis of variance and Pearson’s Product Moment correlation at 0.01 - 0.05 significant level. The study found that 1. 71.4% of the samples were female and 41.0% of the samples were high school graduates. 2. The sampling adolescence had good knowledge of food and nutrition. Different gender had significantly different level of food and nutrition knowledge at 0.01 while different level of study had no different level of food and nutrition knowledge. 3. The sampling adolescence had food and nutrition awareness at high level. Different gender had significantly different level of food and nutrition awareness at 0.01 while different level of study had no different level of food and nutrition awareness. 4. The sample group had good food and nutrition practice at moderate level with no difference between gender and level of study. 5. There was a positive relationship between food and nutrition knowledge awareness and practice of the adolescence at 0.05. The relationship between knowledge and awareness was moderate and the relationship between knowledge and practice was low.

Grafting of hyperbranched polyamidoamine (PAMAM) dendrimer onto ultrafine silica followed by the introduction of phosphonic acid groups onto branch ends was carried out. First an initiating site was incorporated into silica surface by reacting the silica silanol group with 3-aminopropyltriethoxysilane producing amino-functionalized silica. The free amine group content was controlled by varying ratios of methanol to water in the hydrolysis step of sol-gel reaction. Then grafting of PAMAM was performed by repetitive reactions between Michael addition of silica amino groups to methyl acrylate and amidation of the resulting terminal methyl ester groups with ethylenediamine. Amino group content in each generation was determined. This was found to be significantly lower than theoretical value due to unavoidable side reactions. After the G3.0 hyperbranched PAMAM grafted onto silica was synthesized phosphonic acids functionalization of the terminal amino groups by the Mannich type reaction was carried out. The phosphorylated hyperbranched PAMAM grafted silica was achieved and its application on cotton fabric to produce phosphonated cellulose was studied.

The objectives of this research were 1) to study the knowledge about healthy food;2) to study the attitude towards consumption of healthy food;3) to study the relationship between the individual of personal factor and health factor and 4) to study relationship between knowledge and attitude towards of healthy food of high school teacher in Nonthaburi that influenced their behaviors. Questionnaires were used as a tool for collecting the data and the data was analyzed by using percentage mean standard deviation t-test f-test and Pearson correlation (r). Most of the responders of this research were female. Age group was between 51-60 years old. Height group was between 151-160 centimeters. Weight group was between 51-60 kilograms. The majority of their salaries were between 28001-33000 Baht. The level of personnel sickness was low. The level of understanding of how to consume healthy food was high. The attitude of consuming healthy food was high level. But the behavior of consuming healthy food was mostly at moderate level. According to the study of relationship between the individual of personal factor and health care factor the results were: there was relationship between sex and behavior of consuming healthy food statistically significant at the .05 level. Moreover the study of relationship between the knowledge and attitude of consuming healthy food of high school teacher showed that it had an impact on their behavior which was statically significant at the .05 level.

The objective of this research is to study the factors of resource and investment affecting to the number of post graduate students of Rajamangala University of Technology Phra Nakorn. The samples of this research are to survey the group of lecturers from 9 faculties by answering the questionnaires.

English is now regarded as an important medium for international communication among people all around the world in politics education economics and tourism. Vocabulary is an important fundamental element for learning English. It is necessary for students to have lexical knowledge to develop their language proficiencies and communicative competence but Thai undergraduate students are not generally equipped with sufficient lexical items. The concepts and pedagogical implications of the lexical-based learning approach are proposed. It is hoped that this article will be highly beneficial to syllabus design and language instruction in the near future.
