This special project is 1) to develop World Phenomena Game for Grade 3 students 2) to measure knowledge after using World Phenomena Game and 3 ) to study user satisfaction after playing World Phenomena Game. In this study an offline ADVENTURE RPG personal computer game was created and validated by 3 professionals with medium level. Then the game was put to test with a sample group of 10 Satrivoranart Bangkhen School’s Grade 3 students. Quiz and questionnaires were distributed to collect student’s knowledge and satisfaction. During data analysis a attest was performed with t-Test = 1.83 p=0.05. indicated that student knowledge after playing game was statistical higher than their knowledge before playing game Furthermore overall user satisfaction was at high level (𝒙̅=4.30 : SD=0.90).

The purposes of this research were 1) to study the personal student factors of a vocational certificate type of Home Economics Phetchaburi Vocational College 2) to study the importance and the decision to study for a vocational certificate type of Home Economics Phetchaburi Vocational College 3) to study relationship between the personal factors and the importance of the decision to study for a vocational certificate type of Home Economics Phetchaburi Vocational College. The sample used were 148 students who are studying in vocational certificate type of Home Economics Phetchaburi Vocational College. The instrument used in this thesis was questionnaire. The statistics based on the data analysis include percentage frequency values average standard deviation and Chi Square. Analysis of statistical data by a computer program. The results showed that 1) the personal student factors of a vocational certificate type of Home Economics Phetchaburi Vocational College were no effect for the decision to study in general. 2) the learners pay 7 sides attention to the study for a vocational certificate type of Home Economics Phetchaburi Vocational College in general were rated at high level. When considering each side it was found that every side was rated at high level. Shortage average form most to least is career the college environment learner development activities teachers curriculum and media materials and equipment that support teaching. 3) the relationship between respondents’ general information and decision to study for a vocational certificate type of Home Economics Phetchaburi Vocational College found that gender related with media materials and equipment that support teaching age related with college environment and field of study related with image of college is statistically significant at the 0.05 level. The relationship of grade point average (GPA) and revenue of learners per month didn’t relate 7 sides with the decision to study for a vocational certificate type of Home Economics Phetchaburi Vocational College is statistically significant at the 0.05 level.

The objectives of this research were to 1) select a basic cereal formula suitable for milk production from cereals. 2) Study the appropriate amount of sugar used in the development of panna cotta formula from cereal milk. 3) Study the appropriate amount of sweetener (erythritol) in the Phuket pineapple sauce recipe. 4) Study the proper ratio of Phuket pineapple sauce for topping on cereal milk panna cotta. 5) Study the nutritional value of panna cotta Topped with Phuket pineapple sauce. The sensory quality was assessed using a 9-point liking score (9 - Point Hedonic Scale) tasting method. It was found that 1) the tasters accepted the grain ingredients used in the production of cereal milk formula containing 500 g of corn. and millet soybean mung bean black bean red bean and white bean using the same amount of 50 g of each type. 2) The tasters accepted the ratio of 10% sugar to the ingredients in the cereal milk panna cotta recipe. 3) The tasters recognized the use of 6% erythritol of pineapple in the Phuket pineapple sauce recipe. 4) The tasters recognized the ratio of Phuket pineapple sauce in the cereal milk panna cotta recipe of 1: 2 or the amount of 10g of sauce for topping 20g of panna cotta per cup. The scores of liking for appearance color smell taste texture and overall liking were 8.2 8.07 7.77 8.27 8.00 and 8.30 respectively which were in a high level of liking. 5) The nutritional value of basic panna cotta panna cotta from cereal milk formula and panna cotta from cereal milk with Phuket pineapple sauce formula had protein content of 3.17% 2.54% and 2.79 % respectively. Carbohydrates were found to be 27.44% 16.03% and 21.63% respectively. Fat content were 8.17% 0.44% and 0.27% respectively and fiber were 0.00% 0.55% and 0.71% respectively. Therefore cereal milk panna cotta topped with Phuket pineapple sauce recipe is suitable for the health-conscious consumers due to its reduced fat content and in Phuket pineapple sauce using erythritol as a sweetener grammar the energy of nutrients. It is also suitable for consumers who are allergic to milk as it does not contain cows milk and also has good nutritional value.

This thesis presents improving power quality in power distribution system with integration of photovoltaic energy distributed generation having objectives to improve power quality in distribution system model of voltage sag and voltage swell in distribution system model of power loss in distribution system application of mathematical model model of power generation by using solar energy and distributed generation connection technique simulation. In this thesis the power flow was tested with Newton-Raphson algorithm joining with mathematical model. The case study was done by reduction of power loss in distribution system by using techniques of connection of distributed generation joining with model of distribution system 33 bus. The case study about improvement of voltage sag and voltage swell in distribution system used connection techniques of distributed generation joining with model of distribution system 69 bus. The study found that technique of connection of distributed generation that was presented could reduce power loss and showed the percentage of improvement of voltage sag and voltage swell in distribution system especially voltage sag case according to IEEE 1159-1995 standard. This thesis showed that severity level of voltage sag depended on the size and duration of each distribution system model situation by photovoltaic energy distributed generation can reduce voltage sag.

The objectives of this research were 1) to study the behavior and decision to buy online food of vocational students in Phitsanulok Province 2) to compare of personal factors with behavior and decision to buy online food of vocational students in Phitsanulok Province and 3) to study online food shopping behavior affecting to buy online food decisions of students vocational in Phitsanulok Province. The research was a quantitative research using questionnaires from 400 vocational students in Phitsanulok Province. Data was systematically analyzed by percentage mean standard deviation (S.D.) t-Test One-way ANOVA and multiple regression analysis. The result showed that the behavior of buying online food was at moderate level. The decision to buy online food was at moderate level. Difference Personal factors including gender year of study type of subject housing type and monthly income had different of behavior of online food shopping with no statistical significance. Difference Personal factors including type of subject and monthly income had different of decision to buy food online with statistical significance at .05. Online food purchasing behavior effecting decision to buy food online with statistical significance at .05.
