The objectives of this research were to construct a jar oven for the production of roasted chicken using heat from far-infrared radiation and to find the amount of electricity and specific energy consumption used in the production of roasted chicken. The physical properties in terms of color softness cooking yield and water holding capacity of roasted chicken were also investigated. By using far-infrared radiation at electrical power levels of 1000 1200 and 1400 watts to roast marinated chicken which had an initial mass of about 1650 grams until the mass of the roasted chicken had a lower than 1220 grams. From the experimental results it was found that the production of roasted chicken at far- infrared radiation with a high electrical power level requires significantly less electricity and specific energy consumption than that with low electrical power level (P≤0.05). Roasted chicken breasts with far-infrared radiation at 1400 watts had significantly higher lightness (L value) but lower redness (a value) and yellowness (b value) than those of 1000 watts (P≤0.05). However lightness (L value) yellowness (b value) and redness (a value) of the roasted chicken breast with far-infrared radiation at 1200 watts were not significantly different from those at 1000 and 1400 watts (P>0.05). The shear force and water holding capacity of roasted chicken were significantly increased when the electrical power levels of far-infrared radiation increased (P≤0.05). Moreover the electrical power levels of far-infrared radiation (1000 1200 and 1400 watts) did not significantly affect the cooking yield of roasted chicken (P>0.05).Sponso

Thailand is one of the few countries in the world that provides the whole value chain of the textile industry with over 4700 local textile producers and 800000 to one million workers making this industry the second-most important employment sector. In 2016 the industry’s export revenue was valued at almost USD 7 billion contributing to over 3% of total exports. The Association of Southeast Asian Nations (ASEAN) is the biggest international market for Thailand clothing export (23%) and expected to become the worlds fourth largest market by 2030. However Thai cloth entrepreneurs are facing major problems that demand attention including labour costs new design and product development and in particular online marketing. The Thai fashion and textile industries should define a clear strategic move through integrating textile with fashion with a view “toward sustainable creative industries with strong soft power”. The purpose of this study is to analyse competitiveness of Thai cloth entrepreneurs in relation to online management and integrated marketing communications (IMC) in the ASEAN market. The research instrument involves a descriptive cross-sectional mixed-method study in Thailand. For quantitative data 60 cloth entrepreneurs are invited to complete a questionnaire before and after our “online management and IMC” training programme and a qualitative in-depth interview study is conducted with 10 cloth entrepreneurs. The 2017 survey returned 100% participation with general agreement that a website and Facebook are the most important IMC tools for online marketing in the ASEAN market. Before training the participants had knowledge and skills regarding the ASEAN Free Trade Area (AFTA) online communication and social media tools in intermediate level while they had less knowledge and skills concerning social media web design and online gallery. After training the statistics show an increase in entrepreneurs’ level for all knowledge and skills. Furthermore the findings from in-depth interviews show that with regard to entrepreneurial competitiveness in relation to the ability of online management and IMC there is a requirement for further training and government support. In addition the 10 cloth entrepreneurs agree that time management and quality of product and service control are very important for online business.

Nowadays Thailand is realizing the economic value of earthworms. Earthworm farming is a driving force that can stimulate the Thai economy. The objective of this project is to measure the humidity and temperature properties of the worms the two boards are circuit boards in microcontroller. These are the WeMos D1 ESP8266 board and NodeMCU ESP-32S board. The WeMos D1 ESP8266 board to measure the amount of water and temperature of of the soil and can turn the water supply on or off automatically. The NodeMCU ESP-32S board has a database system to collect real-time humidity and temperature data. The data is processed and displayed via a web interface. The experiment showed that in regard to earthworm farming the soil moisture alert system in the earthworm closet has a temperature accuracy of 28.5°C. The top soil has a humidity accuracy of 65% the middle soil has a humidity accuracy of 67% and the lower soil has a humidity accuracy of 67%. This allows the ideal moisture and humidity levels for the propagation of earthworms to be maintained. The alert system displays the temperature and humidity in the earthworm closet and can turn the water supply off if the soil moisture level gets too high for the worms - this can all be monitored via the web application. .

The National Institute of Educational Testing Service (Public Organization) reported that English communication skills are a problem for most Thai students and they received the lowest average score for this subject. Therefore this highlights an important obstacle facing Thailand in developing the country. The aim of this paper is to compare student achievement and communication skills in English in the faculty of business administration of universities in Rattanakosin (Bangkok) Thailand with the intention of determining ways to increase student achievement. The research tool employed in this quantitative research study is a questionnaire to enable statistical analysis from the desired sample of 403 subjects. The F-test and Eta correlation findings show there are low relationships between five factors of achievement (planning and preparation comprehensible input intake activity output and evaluation) and student communication skills (listening speaking reading and writing). The results indicate that English teachers by having the professional knowledge and teaching skills are more responsible for improvement in Thai student English communication. In addition more pressure needs to be placed on universities and Thai government policies to increase opportunities and to encourage Thai students to use English in their daily lives.

This research aimed to develop paper from oil palm empty fruit bunch (Fb) oil palm mesocarp (M) and paper mulberry (P) with chitosan coating to be used as single-use paper bag for dry food products. The optimal pulp preparation conditions for Fb M and P fibers were boiling in 25 25 and 15% NaOH solution at 170 170 and 100°C for 3 hours respectively. The optimal H2O2 concentrations for bleaching of Fb M and P pulps were 40% 40% and 0.2% respectively. The obtained pulps were used to prepare papers with the basis weight of 109 g/m2 . The papers consisted of Fb M and P pulps at ratios of 70:0:30 (FbP) 0:70:30 (MP) and 35:35:30 (FbMP). It was found that FbP paper showed superior physical and/or mechanical characteristics than those of MP and FbMP. FbP papers were then coated with chitosan solutions (0.2-0.6%) to further improve their mechanical properties and reduce their water absorption characteristics. The optimal concentration of chitosan was 0.4%. This study showed that all three types of pulps could be used to produce papers that had equal or superior mechanical- and water adsorption properties as compared to those of commercially available paper bags made from wood pulp.
