Defrosting at evaporator panel is one of working cycles in freezer. Power consumption in defrosting does not meet the objective of using freezer therefore the approach to decrease power consumption in defrosting is one strategy for energy saving. Normally the cycle of defrosting in freezer is a constant time that specify by referring to the highest humidity period. With this control concept the problem of temperature exchange is not occurred from ice accumulation at evaporator panel but it makes the over necessity of defrosting process in the low humidity season and cause the unnecessary power usage in freezer. This research presents the control approach for defrosting by using the difference of the temperature at evaporator and the temperature at chilling area. By using this approach the defrosting process is operated depend on load and the fan is on or off relate to defrosting time. Test results demonstrate that about 12% of power can be saved by this control approach when compared to constant time control.

The purposes of this research were : 1) A study of knowledge about the nutrition labeling formats GDA of Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon Students 2) A study of attitude towards the nutrition labeling formats GDA of Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon Students 3) Compare knowledge about the nutrition labeling formats GDA Classified by gender years of study and majors and 4) Compare attitude towards the nutrition labeling formats GDA Classified by gender years of study and majors. The sample were 307 first year to fourth year. The instrument was a questionnaire. Frequency percentage mean standard deviation t-test ANOVA and Duncan’s Multiple Range Test were used in data analysis via computer program. The results showed that : 1) The most students have moderate level of knowledge and understanding 2) Students have a high level of attitudes when considering each item it was found that the items with the highest mean were: The GDA nutrition label is beneficial to everyone 3) Compare knowledge about the nutrition labeling formats GDA of Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon Students Classified by gender years of study and majors It was found that students with different levels of education and disciplines had different knowledge about nutritional labels in the GDA except for students with different sex. Knowledge of nutrition labeling according to GDA not different Statistically significant at the .05 level and 4) Compare attitude towards the nutrition labeling formats GDA of Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon students classified by gender years of study and majors it was found that students with gender education and different disciplines. Attitude toward nutritional labeling according to GDA not different statistically significant at the .05 level.

It means that students in different grade levels have varying satisfaction with the overall lunch program. 3 ) Relationship between personal factors And family factors. Levels of entry Education Level The amount of money received at the school. Education of parents Parental occupation Family income And the food characteristics of students with satisfaction for lunch. The taste of the food the container and the place of service personnel. And cleanliness which is statistically significant at .05. But the relationship between personal factors. And family factors. The relationship between the level of education and satisfaction with lunch taste location and cleanliness. No relationship The relationship between the amount received to school And parental occupations with container preference and equipment have not relationship.

The purpose of the study “Designing of Printed Textile Inspired by Thai Art Mural In Ayutthaya Period : A Case Study of Wat Yai Suwannaram Phetchaburi” with objective to study and design Printing Fabric from the Inspired by Thai Art Mural In Ayutthaya Period : A Case Study of Wat Yai Suwannaram Phetchaburi. And study the satisfaction and design the printing design which to produce as product to cover shoulders by using the questionnaires as a tool in collecting data from the group samples which the woman working age of state departments and private sectors in the office of United Center Building who is popular use the product to cover shoulders Bang Rak District Bangkok Metropolis for 50 persons by grouping (Purposive sampling). The analyze data by using statistic at 100 % for average value and deviate standard the result of study found that the most appraisers are between age 25-30 years old education level is bachelor degree and income between 15000–20000 Baht. The most appraisers consider first are first select to buy the fabric with design and the prices most appraisers favor to buy the price between 300–500 Baht. Designing of Printed Textile Inspired by Thai Art Mural In Ayutthaya Period : A Case Study of Wat Yai Suwannaram Phetchaburi. All 3 groups of color consist of Group A tone white is natural Group B tone color is cold color Group C is hot tone for 3 patterns total pictures are satisfied at level X = 4.25 S.D.=0.59 when compare to various sides and found that is satisfaction level in all sides that the design the printing pattern on color technic of printing material and other useful usages by design pattern fabric color printing technic material and other usages by design the printing pattern. Picture No. 1 Total pictures they are satisfied at level X = 4.28 S.D.=0.60. Tone group is very satisfaction that is B Group tone is calm.
