Problem with the development of performance for racing cars. When a car is without a front wing and rear wing it will affect the racing car unstable. So we had an idea to study and design the front wing and rear wing for installation on a student formula racing car to increase efficiency the racing car turning when is compared with the racing car without front wing and rear wing. In operation. First plan the implementation of the project. Then study subject content such as Computational Fluid Dynamics Fluid Mechanics Aerodynamics TSAE competition rules and steps to using the SOLIDWORKS Program. We use SOLIDWORKS to compare the aerodynamic performance of each front and rear wing and analyze the results. Flow Simulation using the SOLIDWORKS Program We have got Flow Simulation performed on the front wing and rear wing of 1 2 and 3 elements. In terms of flow simulation we use a 50 km/h wind speed to hit the front and rear wings. The results showed that the front wing and rear wing when assembled with a car. We have studied and selected the angle of attack that has the highest life coefficient to be assembled on the Student Formula Racing Car. The Front Wing and Rear Wing are 2 elements of the Front Wing and 2 elements of the Rear Wing. They have a Drag Coefficient of 0.38 and a Lift Coefficient of 0.30.

The objectives of the research were: 1) to develop and find the effectiveness of learning activities based on the concept of design thinking process to promote self-development of undergraduate students; Rajamangala University of Technology Phra Nakhon 2) to study the satisfaction of learners with learning activities based on the concept of design thinking process together with learning management. The samples used in the research were 30 first-year students who were accompanied by specific selection The tools used in the research were an evaluation form. and the student satisfaction assessment form The results of the research showed that 1) learning activities based on the concept of design thinking process together with learning management to promote self-development of undergraduate students Rajamangala University of Technology Phra Nakhon It focuses on students understanding of the problem through interviews with those who involved in a problem or problem situation rely on working together There is a plan to conduct research analysis to exchange knowledge and experiences. Develop a piece or work to solve problems based on knowledge and ideas. Science and technology consists of 5 steps: 1) preparation and in-depth understanding 2) problem framing stage 3) planning/brainstorming stage 4) prototyping stage and 5) testing and evaluation stage. learning activities The efficiency was 81.28/83.86 higher than the 80/80 criteria. 2) The self-development assessment was at a good level. 3) The students satisfaction with the learning activities based on the concept of design thinking process in conjunction with overall learning management was at a high level.

online media has increased. At the same time Chinese students opportunities to learn Thai through real-life experiences in Thailand are limited by such circumstances. Chinese students need more online Thai teaching media to improve their language skills. Therefore the researcher is interested in studying the use of Thai language teaching and learning online media of Chinese learners. A questionnaire was used to collect data form Chinese Learners with Thai Major in Bangkok and Rural Areas. The results are as follow: Smart Phone is the most use device for use online media. Google translate application is the most use online media. The mostly of participants use online media for translation and interpretation. The mostly of participants choose and use their own decision after familiar with media. And the top three most common media usage problems are: First lack of concentration in online class. Second the content of Thai language teaching and learning online media is insufficient to meet expectations. Third the translation application cannot be translated correctly. From the in-depth interviews it was found that The most satisfying online Thai teaching medium is Zoom. The characteristics of Thai online teaching media that are most satisfied with the use are ease of use. And The most important factor in choosing online Thai language teaching materials is the accuracy of the information.

The objectives of this research were 1) to study factors that promote and support entrepreneurial skill building for students of the Faculty of Liberal Arts. Rajamangala University of Technology Phra Nakhon 2) Develop a learning model to enhance entrepreneurial capacity For students of the Faculty of Arts Rajamangala University of Technology Phra Nakhon which summarizes the results of the study as follows: The results of a study of elements and indicators of entrepreneurial competency for setting goals developing and evaluating student competency. with the research process to analyze the exploratory factor analysis (EFA) sample of teachers Faculty of Arts Rajamangala University of Technology Phra Nakhon found that the performance components of Entrepreneurship of students of the Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon consists of 4 competencies: (1) Competency in promoting holistic thinking: 14 indicators; (2) Evidence-based competency: 8 indicators; (3) Empowerment competence. and quality of care with 11 indicators and (4) ethical competency with 8 indicators of which 41 performance indicators out of a total of 42 indicators were accurate to the actual condition.

The study aims to examine the language use by Chinese students studying in the Department of Applied Thai Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. The Participants were 10 Chinese tertiary students in a two-year-transfer program from Applied Thai Faculty of Arts Rajamangala University of Technology Phra Nakhon. The research instrument used in this study was Thai writing test. The collected data were analyzed by using qualitative approach. Textual analysis and thematic categorization were used to identify the results into four categories: grammatical errors (accuracy and acceptance) theme of story-telling organizational communication and others to describe Thai language used by Chinese students. The results of the study obtained from these Chinese students studying in Applied Thai Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon can be summarized as follows: 1. Grammatical errors (Accuracy and acceptance) concerns twekve sub-categories: (1) using words incorrectly according to the context and the meaning of each sentence (2) misused conjunction (3) writing long sentence without space (4) using words irrelevant in the clause or main clause (5) misspelling (6) using double negators (7) using several ๆ (repetition symbol for one word (8) No indenting content when opening new topic (9) using punctuations wrong (10) degree of words used were not equal (11) wrong sentence organization and (12) incomprehensible word usage. 2. Theme of storytelling: These participants had positive attitudes in story-telling by providing their impression on each point such as their impression on Thai culture Thai human relations appreciation for Buddhism’s faith scenery and atmosphere rules and etiquettes hotel and travel industries Thai foods Thai education as well as the beauty of Thai language. 3. Organizational Communication can be divided into three sub-categories: (1) using bullet points or number to introduce new ideas but the content was relevant to the same topic (2) Using narrative writing to describe story and (3) Using spoken language in narrative writing. 4. Others included eight characteristics as shown in the following: (1) Using verb “มี” (to have) at the start to the sentence instead of using noun or pronouns. (2) High frequency of “ที่” (relative pronoun) to modify clauses in several sentences (3) Using auxiliaries verbs to show hesitant for example “แทบไม่ (hardly) “ไม่ค่อยดี (not quite well) “เกือบ” (almost) and “ค่อนข้างดี” (quite well) (5) Using English word while writing in Thai (6) Using ellipsis point (….) at the end of the sentence (7) Using words to describe characteristics and (8) Arranging sentences by using Google Translate.
