Augmented reality or often called for short that AR is technology that exhibits a virtual image in the real world. Currently this technology has been widely applied to the education domain and responded to the development of essential skills to survive in the twenty-first century. AR is used to promote self-learning according to the constructivist theory which believes that learning is a process arising within the learner. Furthermore the COVID-19 pandemic has conducted to the new way of life which is called the “new normal” in which people avoid seeing each other as well as minimize congestion at all places and contact. Therefore this research aims to study the transfer of processes and technologies used for development. About the COVID-19 situation through the virtual world able to transfer knowledge processes to the public Being aware of the COVID-19 situation and promoting lifelong learning

During the epidemic of the coronavirus covid-19 single-use plastic containing products were in high demand across the community and may not be cost effective to recycle. However repurposing such materials can reduce their environmental impact for instance plastic foam waste can be made into pots for planting different types of plants and trees. By mixing the foam with a suitable cement in a ratio of 1:1 a large range of pot diameters from 4.5-10 inches can be produced suitable for both indoor and outdoor planting requirements. These pot products suitable for growing plants of all sizes are durable unbreakable water tight. Therefore it is a product that repurposes the leftovers from the community and may even add value. This strategy helps reduce the problem of waste and in particular encourages replenishment of green space to nature and the environment which also helps to combat global warming.

Thailand is a country where passenger cars up to 7 people the specified cylinder capacity does not exceed 1500 CC. Most used in Bangkok which is a popular vehicle. Therefore this type of vehicle was chosen to collect data to study behavior and create a driving cycle the selection of the data collection route includes: Ratchadaphisek Road - Rama IV Road Phaholyothin Road and Rama III Road - Narathiwat Road etc. Which the road is in the business district which has a heavy traffic volume. At present there is an epidemic of Covid-19 the government therefore has measures to lockdown. It affects the traffic conditions greatly compared to the normal situation. Therefore data collection was performed on-board measurement. and grouping the time series clustering. In the part of the equipment used to store data including : KYOWA Model EDX-200A It is a highly accurate data storage device. by connecting to Global Positioning System: GPS sensor and connect to notebook The results of the data collection to create a driving cycle of 3 routes in the morning and evening (Peak time).It was found that most of the speed patterns used to create driving cycles were low speed patterns. The frequency of the speed range is close to the real driving and the speed range is in the range of 0-10 km/h. Which show that the traffic conditions on 3 routes are very dense. but driving in some parts can use speed and have the following movement patterns including : acceleration decelerationconstant speed stationary. Each route has different values.

The objective of this study is to observe the relationship between Budget Management and Effectiveness of private schools in Bangkok. The population and sample groups of this study include 691 schools in which 123 focused samples derived from determining samples’ sizes are according to Krejcie and Morgan’s Table. The data used in this study is provided by school administrators chief budget accountants and teachers. The employed study instrument used in collecting data is overall four-part questionnaire survey. Collected data is statistically analyzed by percentage arithmetic mean standard deviation correlation coefficient of Pearson and Multiple Regression Analysis The finding of this research reveals that 1)Private schools’ Budget Administration around Bangkok is general and in each aspect were at a high level : the highest arithmetic mean is account management aspect followed by budget allocation. 2) Private schools’ Effectiveness is general and in each aspect were at a high level : the highest arithmetic mean is teachers satisfaction aspect followed by the ability to adapt from internal and external factors respectively. 3)There is also a positive relationship between schools budget management and schools effectiveness with statistical significance at 0.01

In this study the wind speed characteristic and evaluation of wind power generation at Samoeng district Chiang Mai were investigated using wind speed data and wind direction data during time of January 2011 to December 2011 and measured at a height of 20 40 and 80 m above ground level. It was found that the mean wind speed of 3.8 3.92 and 4.30 m/s. While the mean wind direction of 20.73% and indicating from the southwest. The mean of power density of 107 W/m2 the shape parameter (k) was 1.715 1.633 and 1.783 scale parameter (c) of 3.649 3.651 and 4.092 m/s the mean of wind shear coefficient was 0.19. The evaluation of wind energy for electricity generation by install the wind turbine of Nordex N50 from Germany and Vestas V90 from Denmark were capacity of 800 kW and 3 MW. It could produce annual electricity of 1761379 kWh and 3772400 kWh and the capacity factor show 25.13% and 14.35% respectively. Finally the results showed the northern area of Thailand was suitable for wind power development in further.
