การพัฒนาแอปพลิเคชัน 3 มิติ สำหรับการเรียนการสอนภาษาอังกฤษแบบบูรณาการด้วยเทคโนโลยีดิจิทัลและการฝึกปฏิบัติจริง
It is a must for Thai citizens in this digital era to be able to absorb internationalization skills to survive in the connected world. The study entitled The development of a 3D application for teaching English with integrated digital technology and practical training aims to develop a 3D application for integrated English teaching with digital technology and practical training. Academic literature about 3D application systems the achievability of problems and instructional system design frameworks were reviewed. Additionally in- depth interviews were conducted with 10 key informants using a snowballing technique. The informants were English-teaching experts teachers and social science students. The main findings from the in- depth interviews revealed that most participants did not use HMD VR to learn and practice English language skills while traditional styled teaching was used more often. There had not been much technology-integrated learning compared to language- related games and applications were used. Moreover VR was not applied much to English learning. Accordingly with the devices of Unity Oculus Blender and C# language the development of 3D applications for teaching English with practical training has been developed as an appropriate and optional tool for Thai students with an educational opportunity in English communicative skill practice in the virtual world and accessibility to the useful technology.

This research presents the processing of fresh guava into guava juice product. to be kept for consumption and distribution in the local area It is an alternative career path that helps rural farmers earn more. and create additional careers for the family But farmers still lack the correct technology tools and processing methods in each production process. Therefore there was a problem of insufficient cleanliness taking a lot of time resulting in unacceptable quality and the production is low the postharvest engineering research group has conducted research to find suitable guava juicer. This study is based on working principles of food processing equipment in general use. Come as a guideline to develop improve and create prototypes. The original guava juicer was a grater roller squeezer. There is a guava-sized subsystem consisting of a sub-chamber with grated rollers and the waste water barrier system consists of a juice sieve chamber a waste separation room a spiral conveyer and a sweeper set. various parts that come in contact with the guava juice is made of stainless steel The power source uses a 1-horsepower electric motor a single-phase electrical system a voltage of 220 volts. The machine has the ability to block water at a rate of 250 kg / hour. The juice obtained must be filtered out again with a centrifugal bag filter capable of filtering water at a rate of 50 liters/hour. The prototype guava juice machine costs 40000 baht and the centrifugal filter bag costs 5000 baht. With just one such machine each of these machines can produce 28000 liters of guava juice/year (112000 bottles a year) able to get a return in 0.08 years with an average processing cost of 4.48 baht/bottle which is appropriate in engineering economics. In investment use a ready-to-drink guava juice machine. Fresh guava ingredients are available throughout the year and have 200 business days/year.

The purpose of the Environment Control System for radish with Internet of Things project is to control the environment of radish cultivation in a planting house. The working process of this project is separated into two parts. The first part hardware control is to control temperature moisture and illustrated the working status on LCD. The second part software control is collected data from all sensors and then published results on the website via MQTT protocol. The Environment Control System for radish with Internet of Things project is evaluated by measuring the value of temperature and soil moisture from the system compare with the value from reliable instruments. The test results show that the system can measure the temperature and soil moisture correctly. Moreover the software function of the system has fulfilled the requirements.
การศึกษา 4.0 : การประเมินทัศนคติของนักศึกษาต่อการใช้แอปพลิเคชั่นเพื่อการเรียนรู้ภาษาอังกฤษ
The study entitled “Education 4.0: An Evaluation of Students’ Attitudes towards Using Mobile Applications for English Language Learning” a mixed-method research aims to find out what are the students’ attitudes towards the use of mobile assisted in language learning what factors result in the acceptance and the use of mobile applications for English language learning and what are the application features responding to the students’ needs. The participants in this study were selected based on the convenience sampling method. They were undergraduate students studying at the tertiary level from the first-year to the fourth-year in the Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon in the academic year of 2020. The total number of participants was 131 university students. The research instruments used for data collection was questionnaire which can be divided into four parts as follows: Part 1 general information Part 2 mobile applications used for English language learning Part 3 factors affecting the acceptance and the use of mobile applications for English language learning and Part 4 open-ended questions for additional information and suggestions so as to develop the features of mobile assisted in English language learning responding to the students’ needs. The data obtained from the questionnaire were divided into two types. The quantitative data such as the scores from 4-point Likert scale were analyzed by using descriptive statistics for example frequency percentage mean and standard deviation. In addition to the qualitative data the students’ written opinions were analyzed by using textual analysis word clouds and sentiment analysis of users’ attitudes towards the use of mobile applications for English language learning. Most participants in this study were female university students whose age ranged from 18 to 22 years old. These participants filled in the four rating scale questionnaire: 4 strongly agree 3 agree 2 disagree and 1 strongly disagree to report their attitudes towards the use of mobile applications for English language learning. The results of the study showed that most participants frequently used Youtube and Facebook to develop their vocabulary. The individual factors such as gender age and English language proficiency were not correlated with the acceptance and the use of mobile application for English language learning. The participants also reported that they strongly agreed on the performance expectancy and the perceived usefulness with a low to moderate correlation in each factor. According to the descriptive analysis and textual analysis the results reported that these university students showed positive attitudes towards the use of mobile applications for English language learning because it was easy fast and could access information quickly. One possible explanation for this was their age group. These participants were the members of generation Z who were born with innate digital literacy and the advancement of technology. They were also familiar with social media. However one of the limitations in the study was data analysis since the results of sentimental analysis and textual analysis might be influenced by word segmentation approach. For the content of English the differences between general English and English for Specific Purposes did not result in any decisions on using the mobile application for English language learning.

Objective of this research is to research intelligent hydroponic vegetable cultivation control system for farmers. This is a group of lettuce that needs acid-base (pH) and conductivity (EC) in the same system on the planting table with Dynamic Root Floating Technique System (DRFT). By using Internet of Things (IoTs) devices as sensors For controlling the on-off system of the water filling system the on-off of nutrient solution A and B as well as the water spray system to reduce the temperature at the vegetable growing table. The developed hydroponic vegetable control system can effectively replace the workers labor. Vegetables grown are of the same quality used by farmers. Therefore the developed salad cultivation system could be used as a substitute for farmers. It has an easy to use control system.
