The research aims to 1) promote historic and cultural tourism at royal temples in Ayutthaya province; and to 2) identify ways of promoting cultural tourism sustainably. The research methodology is mixed-method. The quantitative data was collected from approximately 400 Thai tourists by means of questionnaires. The qualitative data was collected by means of interviews with 8 tourism stakeholders in Ayutthaya province. Data were analyzed to identify the frequency percentage mean (x̅) and standard deviation (S.D.) using SPSS. The research found that Thai tourists and tourism stakeholders support measures to develop Royal temples in Ayutthaya including: 1)Wat Phra Sri San Phet; 2) Wat Panan Cheng Worawiharn; 3) Wat Na Phra Maen; 4) Wat Kasattra Thirat; and 5) Wat Phrom Niwat. In order to develop this royal temples there should be co-operation between locals and the private sector to promote sustainable tourism and to preserve the beautiful heritage sites as world heritage sites. The private sector and locals should support sustainable tourism activities and Thai culture to attract tourists who can encourage socio-economic development. In addition tourism facilities should be developed such as tourism landscapes parking areas tourism information public toilets and facilities for the elderly and disabled. Tourism policy should be supported through co-operation between locals and tourism stakeholders. Tourism management authorities and locals should support activities to preserve culture in order to attract more tourists and increase tourism revenue.

This research aims 1) to develop online learning kit for sustainable development 2) to test the effectiveness of the online learning kit and 3) to study attitudes toward online learning kit. The sample used in this research was students from Rajamangala University of Technology Phra Nakhon registered in “World in 21st Century” the first semester of the academic year of 2018 and 36 students were obtained by using a specific random method. The statistics used for data analysis were percentage standard deviation and t-test. The research found that: 1. The online learning kit was developed with the efficiency of 80.91/96.39 which is higher than the standard set 80/80. 2. The outcome of learning with online learning kit for sustainable development was developed higher than before learning at the .05 level of significance. 3. The students have higher attitude towards online learning kit for sustainable. (𝑿̅=4.42 𝑆.𝐷.=0.61)

It is well known that waste spoiled are undesired and one of the main causing of environmental problems and health effects. In Thailand there are growing wastes especially at Thewarat market every year. The causes of the increase in wastes are from economic and industrial expansion which are important issues for the community responsible to manage and correct the amount and types of waste disposed properly before disposal. In the study a preliminary survey by talk and providing the questionnaires were conducted at the Thewarat market. It was found that solid wastes or rubbishes are mostly generated during and after trading process with and without proper can disposal. The stores did commonly dump the solid and liquid wastes around the stores or nearby the bin not inside the bin. The unpleasant observations shown were the solid wastes and dirty water contaminating into the soil and in the waterway and it was not managed hygienically. Uncared by unconcerned sellers during busy market during the day more unrecognized attitudes of the merchants themselves inappropriate placement of food and food waste in the public for the buyers and manucipal wastes generated by people in the surrounding community were normally observed daily. More risks of disease spreading and accumulated rodents insects and pathogens breeding and homing were appeared during at night after the market closed. In the research the campaign and suggestions were operated by the research team the proposed strategies for the waste management at Thewarat market area were including two times of training; discussions and 2 leaflets. These sessions were based on the education on proper waste management highlight on the proper use of right trash bin with the right waste post-sales area management and the use of microorganisms for the production of bio-fertilizers and bio-fermented solution from biodegradable waste in the market community. Moreover the monitoring communities were done for the proper use of trash bin in the community and providing the right waste management. It could bring the benefits to the community at the initial level especially the realization and attitudes in the suitable waste management since approximated 10% shops keep their shops and area nearby clean thus adding a panoramic view with a good image to the Thewarat market.

In this work fiber mat based on silk sericin and thunbergia laurifolia linn extract was developed via electrospinning technique for wound dressing application. The waste cocoons were selected from Nakhon Ratchasima 1 (K1) with appropriate spicy for extracting the silk sericin protein. Trunk of thunbergia laurifolia linn was selected for preparing thunbergia laurifolia linn extract. Polyvinyl alcohol (PVA) with several concentrations were chose and fabricated to fibers by electrospinning technique to investigate suitable polymer concentration for mixing silk sericin and thunbergia laurifolia linn extract. The result revealed that PVA of 9 wt % was suitable due to Several parameters were investigated to prepare the electrospun fiber of silk sericin and thunbergia laurifolia linn extract such as their mixing ratio voltage the distance between the needle and the substrate and the needle size. The results indicated that mixing ratio of silk sericin and thunbergia laurifolia linn extract at 50:50 (w/w) voltage of 15 kV the distance of the needle and the substrate at 8 cm and the needle size of 18 were optimum condition for the fabrication of electrospun fiber with diameter of 100-200 nm and that with smooth and continue feature.

This research aims to study the properties of local plants Phraek Nam Daeng community for the development of a herbal drink and development drink herbal tea. Local plants used in the study was Khlu (Pluchea indica (L.) Less). The leaves Khlu tested phytochemical composition antioxidant testing by testing their ability to reduce the amount of chemicals 11-diphenyl-2-picrylhydrazyl (DPPH) tests the amount of phenol used Folin-Ciocalteus reagent nutritional analysis and the amount of cellulose and developed the herbal drink tea. The research found that 1. Phytochemical composition of Khlu leaf is mainly flavonoids and tannins anthracnones. 2. Extracted from the leaf extract with methanol showed the ability to reduce the amount of substance 11-Diphenyl-1-picrylhydrazyl (DPPH) was the most abundant. Fresh leaves dried leaves and dried leaves were 30 days values at 131.23 ± 1.42 127.55 ± 1.03 and 125.90 ± 1.28 μg / ml respectively. 3. Extracts from the leaf extract with methanol showed the highest phenolic content as follows: fresh leaves dried leaves and dried leaves for 30 days were 84.91 ± 0.54 82.44 ± 1.09 and 81.01 ± 1.25 mg GAE / g dw respectively. 4. The optimal conditions for the process of making Khlu tea is a temperature of 70 °C for 7 hours. The score of sensory evaluation in terms of appearance color aroma flavor (astringent) and overall were 7.37 ± 1.22 7.23 ± 1.16 6.97. ± 1.30 7.00 ± 1.14 and 7.63 ± 1.10 respectively.
