The objective of this study was to khet design by using Thai pattem created on cotton clothes using Thai Khet creation: warp yarn in thousand comb with tightly strengthened cloth while welf yam with hardness together Thai Khet on Thai cotton pattern Traditional Thai Khet waving machine to be adapted by adding front floating hardness pattern hardness wood stepping new pattern weaving plan plotting Thai pattern and making color signals on graph prior khet pattern creation which one graphs column replaces one warp yarn when khet designing have been finished then the following step is desinged plane weaving. The results of the study showed that: there is suitable continuing Thai pattern on cotton cloth: Kanook pattern follows Krajang Ta Ooy pattern and Prajamyam pattern to be combined as graceful delicacy pattern and innovation transferred into Danchang District Supanburi Province.

The purposes of this research were 1) to study problems and needs of designing packages for mixing mangosteen extract soap for the Faculty of Science and Technology Rajamangala University of Technology Thanyaburi 2) to design and develop packages for mixing mangosteen extract soap and 3) to assess the satisfactions towards the packages from manufacturers consumers and packaging experts. The samples consisted of 235 people. A structured interview and questionnaire were used to collect the data which was then analyzed using percentile values means and standard division. The result showed that since there had not been packages for this mixing mangosteen extract soap to be sold in the market four patterns of packages were designed and construced for three products. The three products were 1) 80 grams of mixing mangosteen extract soap 2) 100 ml. of facial cream mixed with mangosteen extract and 3) 400 ml. of mixing mangosteen extract liquid soap. The second pattern was rated a high level of satisfaction by the target group.

This research aimed to study and analyse conditions and problems in designing and developing household and decorative products of One Tambon One Product (OTOP) small and medium enterprises (SMEs) in Pathumthani province. The informants were 4 OTOP entrepreneurs and 205 OTOP SMEs. The research was conducted by means of interviews observations and questionnaires. The data was statistically analysed using frequency percentages mean and standard deviation. The results showed that conditions and problems in designing and developing household and decorative OTOP products ranged from home-based production site a lack of knowledge in product design and development transportation creativity artistic relations product specifications marketing to product design and development laws. Four entrepreneurs from these groups of products: lotus-fiber flowers silk flowers and bamboo lamps were found to have the problem of dyeing materials whilst those from the group of Thai/Japanese clay flowers had the problem of clay. The researcher had analysed piloted and concluded the problems and then passed on product development techniques to the entrepreneurs. It was found that they could use the given knowledge to make beautiful products and they satisfied with the reducing cost of production.

The objective of study was to design and development of spray drying technology for production of salt powder. The process design and build spray dryer that consisted of three parts: an atomizer a drying column and a dry powder collecting unit. The operation of a spray dryer was co-current flow. A drying column had diameter 0.5 m high 1.5 m and heater 15 kW with automatic temperature control PID 220 V AC power. The test used a saline solution. The inlet air temperature had 5 levels: 130 140 150 160 and 170 ?C. The inlet air velocity had 5 levels: 8 8.5 9 9.5 and 10 m/s. The results were a spray dryer be able to saline solution became salt powder with moisture content between 1.0 - 2.5 % (wet basis) which was in the standard of pure consumable salt (TIS 2086-2544) and can be classified at first class that moisture content had no more than 3 %

This paper presents a program developed for calculating magnetic field intensity of high voltage transmission line and high voltage distribution lines. This program was developed with Microsoft Visual Basic and Microsoft Access program was used to store the database of the peak ratings current height and space of transmission lines. The developed program was able to calculate magnetic field intensity of high voltage transmission line and high voltage distribution lines according to 2 standards of Provincial Electricity (PEA): “A 22 kV Single Conductor Circuit High Voltage Distribution System” and “115 kV Single Conductor Circuit High Voltage Transmission System”. The program was able to select structure of the electrical system to be calculated as well as types and specification of Transmission line from the stored database that corresponded with the structure. The calculated output waveforms were displayed on computer monitor. Results from the developed program enable more convenient and faster calculations of magnetic field intensity of high voltage transmission line and high voltage distribution lines and are useful for analysis of possible impacts on electric and electronic devices.
