This research aims to study the important factors that affect the decision making in the manufacturing process development of industrial factories according to the Industry 4.0 concept and to create decision models. The model developed from applying Analytic Hierarchy Process (AHP) to this group of experts focuses on the most strategy and organization factors accounted for 28.3 percent followed by the smart factory accounted for 17.8 percent smart products accounted for 16.3 percent smart operations accounted for 13.1 percent employees accounted for 12.5 percent and the data-driven services accounted for 11.9 percent by the model test results with 3 factories. In conclusion this model can decide the way to improve the production process of industrial plants according to the Industry 4.0 concept that is suitable for the context and limitations of each industrial plant can be used for all types of industrial plants and will directly benefit the decision makers of industrial plants to improve the production process and develop into smart factory based on the Industry 4.0 concept.

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 study were (1) to improve the integrated lesson plans according to the Philosophy of sufficiency Economy : Garland Subject for Mathayom 4 students of Debsirin Nonthaburi School (2) to compare the achievement before and after using the integrated lesson plans according to the Philosophy of Sufficiency Economy : Garland Subject for Mathayom 4 students of Debsirin Nonthaburi School and (3) to study the pleasure of the students towards using the integrated lesson plans according to the Philosophy of Sufficiency Economy : Garland Subject for Mathayom 4 students of Debsirin Nonthaburi School It was one Group experiment research with pre-test and post-test. The samples consisted of 40 mathayom 4 students at Debsirin Nonthaburi School studying Garland subjectsemester 2/2560 The samples were selected by Purposive Sampling The instruments were 3 integrated lesson plans according to the Philosophy of Sufficiency Economy : Garland Subject 30 item’s for achievement-test : Garland Subject for Mathayom 4 students and the questionnaires measuring the student pleasure towards using the integrated lesson plans according to the Philosophy of Sufficiency Economy : Garland Subject for Mathayom 4 students of Debsirin Nonthaburi School The statistical procedure employed were percentage mean standard deviation and the t-test. The finding showed that the integrated lesson plans according to the Philosophy of Sufficiency Economy : Garland Subject for Mathayom 4 students of Debsirin Nonthaburi School in the aspects of moderation reason good immunity knowledge condition and moral were significantly different at the .05 level the practical skill was increased and the students’pleasure on the questionnaires of using the integrated lesson plans according to the Philosophy of Sufficiency Economy : Garland Subject for Mathayom 4 students of Debsirin Nonthaburi School were at the high level ( X =4.38 S.D.=.26)

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 purposes of this research were 1) to study the personal factors of students buying ready made frozen food products 2) to study the knowledge in buying ready made frozen food products of students 3) to study students buying behavior of ready made frozen food products 4) to study the relationship between personal factors and buying behavior of ready made frozen food products and 5) to study the knowledge in buying ready made frozen food products and buying behavior of ready made frozen food products. The sample was 300 students of the Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon. The research instrument was questionnaire. The statistics used to analyze the data were frequency percentage mean standard deviation and Pearson chi-square. The data analyzed by SPSS. The research found that 1) most of students were female age range in 20-21 years studying at 3rd year income of 7001 Baths and live with families. 2)the most students knowledge buying ready made frozen food products moderately level 3) most students bought ready made frozen food products in from 7-Eleven store buying 3-4 times per week fried rice and side dish for lunch cost of buying was 51 Bahts time range of buying was 12.01-18.00 minutes the reason to buy was because it was fast and the influence decision was oneself. 4) relationship between personal factors and buying behavior of ready made frozen food products found that age year of study average monthly income and shelters except sex at 0.05 significance level. 5) knowledge buying ready made frozen food products and buying behavior ready made frozen food products found that no relationship at the 0.05 significance level.
