Ministry of Higher Education Science Research and Innovation has declared the policy towards university intiation with creative warm impressive and students’ improvement reinforcement. It is put into effect to every institute strictly. The research is a mixed-methods paradigm in order to evaluate the results of creative initiation by studying the perspectives on activities as well as the effects of creative initiation. Moreover setting the objectives and creative initiation indicators employing cost-benefit analysis are concerned. With simple random 362 undergraduate students of Faculty of Business Administration of Rajamangala University of Technology Phra Nakorn are the participants of this study. The study not only employs descriptive statistics —frequency percentage average and standard deviation— but also takes the focus group interview to collect data. To do so using purposive sampling to get 13-activity-staff as well as 12-activity-participant helps the researchers to analyze data in many dimensions: important issues and brainstorming for creating the next-time activities. The results found that 1. university students’ perceptions on activity was above average (good); such a type of activity was needed and related to the project’s objective 2. university students shared their opinions towards activity’s effects as followed: 1) positive effect is good; the activity caused unity responsibility and people and environment adaptation 2) negative effect is moderate; university students complied to do the activities but the activity’s processes should be improved. This was because various activities affected mental issues. According to previous activities’ cost-benefit analysis of Faculty of Business Administration they found that the cost of “Rak-Rua-Wang” project was the highest because there was high fixed-cost. On the other hand the project “Jit- Ar-Sa-Pha-Nong-Tham-Dee” had the least cost. To conclude internal rate of return modified internal rate of return and net present value of every project tended to increase continuously since university students in different majors involved in the activity increasingly.

Design of grounding system to protect against lightning and fault is important for both safety and reliability especially for Metropolitan Electricity Authority (MEA) as mostly Metropolitan Electricity Authority operates on overhead networks. This thesis assesses lightning performance for 69 kV 115 kV overhead subtransmission lines 24 kV distribution line using case study from Metropolitan Electricity Authority. Because of the limitation of the right of way distribution feeders are regularly installed together with subtransmission lines in a single concrete pole. Overhead Ground Wire (OHGW) installed at top of the pole and grounding system in concrete pole protects fault current or direct lightning surge to ground. Metropolitan Electricity Authority has developed lightning protection based on an IEEE standard which uses international data for insulation coordination. As a result reliability of the system is lower than the designed value. This thesis suggests a methodology to improve the performance in order to increase the reliability of subtransmission and distribution lines feeding distribution substations. This thesis recommends installation of addition external ground wire on the outer surface of the concrete pole to reduce top pole voltage and back flashover rate or installation of bundle overhead ground wires to protect shielding failure. As all the case studies presented in the thesis which constitute this thesis are applied to existing systems of Metropolitan Electricity Authority it is expected that the proposed methodologies can be served as useful practical guidelines for lightning performance assessment subtransmission lines and distribution lines of Metropolitan Electricity Authority.

Most of Metropolitan Electricity Authority (MEA) electric power system is using overhead line. It is 94% in the system including subtransmission distribution and low voltage system. All of them were installed on concrete pole. At present many public facilities have been built such as Sky-Train. It causes more constrains for construction with concrete pole due to lack of right of way. MEA needs to using electrical monopole plays an important role. It’s easier than concrete pole for construction and it requires less construction area than concrete pole. The thesis evaluation of lightning performance in subtransmission line 69 kV study on MEA. Case lightning strike on overhead ground wire (OHGW) at pole top of electrical monopole with suspension insulator Focusing on three factors is pole top voltage critical current and back flashover rate (BFOR). ATP-EMTP software is used for simulation. The results show that BFOR is reduced by 79% on electrical monopole structure with suspension insulator compared with existing concrete pole. BFOR is also reduced by 33.17% on concrete pole with external ground wire. The results could be served as a guideline in subtransmission line design and improvement in MEA power system.

The purpose of research is to study the carbon footprint evaluation of products for thread turned Tungsten Carbide 16ER60 of production. To assess amount of greenhouse gas emissions that affect the environment. The key component in the calculation include raw material production material energy and waste January 2018 and March 2019. The scope of the study is the assessment of Business-to-Business (B2B). From the assessment of the carbon footprint it was total of greenhouse gas was about 1.1559 Kg CO2e which was divided from raw material about 0.0118 Kg CO2e and production process about 1.1441 Kg CO2e. From the improvement reducing electricity of sintering furnaces machine and lighting system was reduce greenhouse gas emissions about 0.3249 Kg CO2e or decrease percent 71.88 CT

This research has focused on the efficiency of using online media computer graphics based on concepts and theories of learning networks for students in computer science faculty of science and technology Rajamangala University of technology Phra nakhon because at present the network access can be accessed anytime the researcher has the idea to measure the effectiveness of learning in computer graphic courses. that students will have much interest 1) The population of this study consisted of 30 undergraduate students who attended the Computer Education and Training subject. The instruments utilized to design the lesson included. Tools used to develop lessons consist of a system LMS 2) The tools employed in evaluating quality of the online lesson consisted of the learning management plans a 20-item pre-and post-test an authentic assessment with rubric scores and a students’ satisfaction questionnaire. The results revealed that 1) The efficiency of the online lesson constructed was at 85/84 which was higher than the criterion set (80/80) 2) The students’ learning achievement was higher at .05 level of significance 3) The students’ satisfaction on the online lesson was at high level 4.31
