Drying of ground fish slices using superheated steam  combined with hot air
Drying of ground fish slices using superheated steam combined with hot air

The objectives of this research were to study the changes in the moisture of ground fish slices during drying with superheated steam combined with hot air and to compare the physical properties (in terms of color hardness toughness and shrinkage) as well as sensory evaluation of dried fish slices. Two drying methods were performed (i.e. superheated steam drying at 140 ?C combined with hot air drying at 110 ?C (SSD+HAD) and hot air drying at 110 ?C combined with superheated steam drying at 220 ?C and hot air drying at 110 ?C (HAD+SSD+HAD)). The ground fish samples were produced at sizes of 50?50?1.3 and50?50?2.2 mm (WDH). The samples with the initial moisture content of around 205-215% dry basis were dried until the final moisture content of about 20% dry basis. Results showed that the samples with 1.3 mm thickness had shorter drying times than those with 2.2 mm thickness. The samples dried by SSD+HAD and HAD+SSD+HAD were similar in the drying time. In term of qualities it was seen that the lightness of dried samples decreased but the hardness toughness and shrinkage percentage of dried samples increased when the samples thickness increased. Dried samples obtained from SSD+HAD had higher lightness hardness and toughness but had lower percentage of shrinkage than those obtained from HAD+SSD+HAD. Moreover it was found that dried samples obtained from HAD+SSD+HAD had the highest sensory scores.

This research aims to study the production selling and applications of Kamar Band products (Pa-Koa-Ma) manufactured in a community. The Kamar Band was used to make different styles of bags which will be sold as an OTOP merchandise. The production process was developed and then transferred to the selected community members. Firstly 60 designs of bags were developed and divided equally into 4 groups including a tote-bag flirt-bags messenger-bag and tuck-bag. Subsequently one designed bag was chosen for a technology transfer to 40 members from a community at Tumbon Nongkhao Amphur Tamuang Kanchanaburi Province. After the transfer process questionnaires were used to evaluate the satisfactory of the participants. The collected data was analyzed statistically and concluded. The basic information reveals that all participants are female. Most of them are above 51 year old having lower secondary education. They are farmers having monthly incomes of 5001-10000 Baht. After evaluating the satisfaction for three categories: training preparation trainers and overall impression the result shows that the participants have highest satisfaction for all categories.

This article aims to synthesize literatures in Educational Robotics and presents key features of systematic literature review and structured meta-analysis of the literature. Population consists of 247 papers from 10 databases ranging from 1996 to 2012. Results show that common problems in Educational Robotics are high cost of tools license and differences in students’ background knowledge. Trends of existing researches focus on development of software and low cost robot training package in order to promote students’ practice in problem-solving skills and teamwork in experience-based learning to enhance self-motivation and experience with real world applications. It was also found from the synthesis that qualitative-based evaluation of tool and learning achievement process was rare even though it is a key factor that indicates quality of learning process.

This reseach presents development of engineering education about automation engineer. The objectives of develop education technology automatic control systems. The development and pilot institutions or company associated with the agency so that it can compete with companies in the ASEAN countries. In the design research and development training kit to support and use in teaching and learning control liquid level like an industry as the reality of the industry. The trainner could be applied to the advanced control theory for experiment in teaching or training in class room similary industry personnel. The hardware is compatible with existing standards. It is increase the capacity of existing courses such as a course to learn basic control system consists of a sensor industry around the outside parmerter. The sensor could be real measured and simulation from plant model. The student can control the virtual experiments. Controller could be learning such as PLC Microcontroller and computers. The experiments determine relation of correlated response signal ON-OFF and PID by adjust Gain control systems that have tenor as same as control theory which describes the response of the control. The experimental results of this the research collected in the operating room. The ability to control the system to could be doand meet the taget and follow by objective

Development of local product made from Pahkanmah based on integration of local wisdom and principle of fashion design to promote community career : A case study of Wanon-nivat district Sakon-Nakron province. The aim are Promoted the concept of product development from Pahkanmah development a model of clothing from Pahkanmah based on integration of local wisdom and principle of fashion design and knowledge transfer development of clothing from Pahkanmah to Community of Wanon-nivat district Sakon-Nakron province. There were tree issue 1. Making Knowledge in products development from Pahkanmah to guide the creative product of the community. 2. The communicate knowledge in product creation to community and standardize the product including the addition the target group. 3. Promotes the Innovation of Product design commercial creation create of community identity for potential development and sustainable occupation. Data were analyzed using a descriptive analysis on the concept of local wisdom from a weaving bee Pahkanmah Wanon-nivat District Sakon-Nakron Province with concept of fashion design and analyzed manner statistics data of the questionnaire about the requirement and the contentment that have to build clothes format from Pahkanmah of location in woman working age between 25 year - 35 year the residence is in Bangkok and the perimeter 200 persons amounts for take the data has that to go to apply in designing and produce clothes from Pahkanmah. The results showed that local wisdom from Pahkanmah Wanon-nivat district Sakon-Nakron province have transmitted passed on from generation to generation from production to household appliances then have design and color follow the inventory obtained from the local when bring the products a clothing design then has to use the patchwork technique and applied placement pattern of Pahkanmah the results forms and patterns interesting and appropriate with trend fashions. The community groups to gain knowledge and can use wisdom from Pahkanmah and fashion design idea the inventive uniform for woman to promote community career.
