This research was aimed to study 1) The knowledge and dietary habits of Faculty of Medicine Vajira Hospital Navamindradhiraj University personnels 2) body mass index of personnels 3) relationship between dietary habits and body mass index. The sample used in this study were personnels of Faculty of Medicine Vajira Hospital Navamindradhiraj University. The survey was conducted on 297 samples who were non-medical and nurses personnels. Simple Random sampling method was used. The tools were foods and nutrition knowledge dietary habits and nutritional status questionnaire. Data were analyzed by using frequency percentile mean and standard deviation. To study relationship analysis correlation coefficient analysis was used. The study revealed that 66.00% of Faculty of Medicine Vajira Hospital Navamindradhiraj University personnels had very good nutrition knowledge 13.10% 12.10% 6.70% and 2.00% had good moderate passing and not passing knowledge respectively. The food consuming dietary habit was in good 52.50% 38.00% in moderate 7.40% in very good and 2.00% was in fair in orderly. 50.20% of the group had normal nutritional status while 40.70% and 9.10% were over nutrition and low nutritional status respectively. The study of the relationship between nutrition knowledge and consumption behavior revealed that there was a significant relationship between the two variables at significant level of 0.05

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.

Utilizing coconut coir fiber can offer an alternative method of adding value to agricultural wastes and help to conserve the environment. The aim of this research was to investigate the potential use of coconut coir fiber as cement composite as an environmentally material. The properties of cement composites mixed with different proportions of paper wastes were compared with ordinary white Portland cement. In addition the surface structure and chemical characteristics of samples were examined by a scanning electron microscope (SEM) and energy dispersive x-ray spectrometer (EDS). The results show that the main elements - C O Ca Al Si and K respectively were found in cement composites. The compressive and flexural strength of the cement composite decreased with an increase in the coconut coir fiber volume fraction.

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.

The objective of this research is: 1) To study of the satisfaction of the Secondary School Lunch Program at Rajinibon School 2) To compare the differences in satisfaction among the Secondary School Lunch Program at Rajinibon School and 3) To study the relationship between the personal factor and the family factor and satisfaction in the daily food consumption of the Secondary School Lunch Program at Rajinibon School. The stratified random sampling consisted of 259 secondary students at Rajinibon School. The tool used was a questionnaire data analysis The frequency percentage mean standard deviation Analysis of variance And Prasit. The study indicated that 1 ) the satisfaction of the Secondary School Lunch Program at Rajinibon School is relatively low 2.48 percent. Overall 2 ) comparative study results of the different student grade levels and their satisfaction of the Secondary School Lunch Program at Rajinibon School produce the value statistically significant at .05. 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.
