Probiotic is a micro organism that is useful for human bodies and can help creating balances for human intestinal system. The objective of this research is to compare amounts of fat substitutes supplied in the industries in order to determine their ability to encapsulate Probiotic microbes in the production of yoghurt ice cream to ensure maximum survived Probiotic microbes. In this research two fat substitutes Purity SM 100 and CRYSTAL texTM 648 were used to substitute skim milk in the standard formulas in order to study numbers of survived Probiotic microbes and to test the sensory acceptance. For the sensory acceptance it was found that the Probiotic yoghurt ice cream containing 20% Purity SM100 is acceptable at the maximum significance (p ≤ 0.05) because its flavor and taste was better than other samples as well as the best overrun with statistical significant differences (p ≤ 0.05). However by addition of both fat substitutes at different concentrations pH values of Probiotic yoghurt ice cream products did not have statistical significant differences (p ≥ 0.05). When Lactobacilluss acidophilus Bifidobacterium and Streptococcus thermophilus microbial starters were added into the Probiotic yoghurt ice cream using both fat substitutes in place of skim milk at ratios of 10% 15% and 20% respectively under a storage condition of -20oC for 4 weeks it was found that types and amounts of fat substitutes affected the surviving rate of Probiotic microbes in the product with a statistical significance (p ≤ 0.05). The addition of fat substitutes Purity SM100 and CRYSTAL texTM 648 at all concentration levels made Probiotic microbes survive in the product which illustrated that both fat substitutes used in above experiments could encapsulate Probiotic microbe cells. The survived Probiotic microbes were in the range of 108 – 109 CFU/ml in comparison to the Probiotic yoghurt ice cream with the standard formula without the addition of fat substitutes that has survived Probiotic microbes of only 106 CFU/ml.

The purposes of this research was to study and to compare the students’ satisfaction of the school lunch project in Demonstration School of Suan Sunandha Rajabhat University classified by gender age grade levels and amount of participation in the school lunch project. A sample of this research was 297 students selected by stratified sampling Research instrument was the questionnaire. The data were statistically analyzed in terms of frequency percentage mean standard deviation and t-test for dependent samples. The results of the research indicated that : 1. The satisfaction of most girls from grade levels 1-3 and amount of participation in the project were at high level in all aspects of food services place equipment cost and personel. 2. The satisfaction of students with different genders ages grade levels and amount of participation toward the school lunch project was significantly different at 0.05 level.

The objectives of this research are ; 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 at Nonthaburi that influence their behaviors. Questionnaires were used as a tool for collecting the data and the data was analyzed using percentage mean standard deviation t-test f-test and Pearson correlation (r) Most of the responders of this research are female. Age group is between 51-60 years old. Height group is between 151-160 centimeters. Weight group is between 51-60 kilograms. The majority of their salaries are between 28001-33000 Baht. The level of personal sickness is low. The level of understanding of how to consume healthy food is high. The attitude of consuming healthy food is high level. But the behavior of consuming healthy food is mostly at moderate level According to the study of relationship between the individual of personal factor and health care factor. The results are: there is 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 that impact to their behavior show knowledge and attitude have relationship to behavior to consume healthy food statistically significant at the .05 level

The objectives of this research were to study the snack consumption behavior of vocational education students certificates level as relate to sex age education level income knowledge of snacks and to study relationship of different levels of knowledge of snacks to sex age and education level of vocational education students certificate level. Sample of 267 home economics students ages 16-18 years home in Kanchanaburi Suphanburi and Nakhonphathom were randomly selected by stratified random sampling. All data were colleted by questioners and analyzed through percentage mean standard education chi – square T – test and F – test. The results of this study indicated that the snack consumption behavior of vocational education certificate level studied in the western Region Vocational Education Institutes had medium level of knowledge about snack. Sex age education level and different income were not significantly related to snack consumption behavior. Different sex and age did not contribute to knowledge levels about snacks.

We present the comparison of CDMA MAC protocol with and without beat noise by using 2-D optical CDMA MAC protocol over WDM networks. We use the asymmetric primehop sequence code. Moreover we analyse the effect of the number of available wavelengths in tenns ofaverage number of attempted to transmissions per time slot (offered load) and beat noise is considered. The presented numerical results based on the throughput and delay time versus the offered load. We divide into two parts. The first one we consider the effect of the number of available wavelengths. Another is the effect of with and without beat noise in the 2-D OCDMA over WDM systems.
