แผนฉนวนกันความร้อนจากใบสักเพื่อลดความร้อนให้กับอาคาร
This research aims to investigate and test the feasibility of the production of natural teak sheets and study the appropriate production methods. Study physical properties and mechanical properties to compare with industry standard insulation sheet. The ratio of tattoo and hyacinth. 5% 7% 9% of the material were dried at 400 600 800 kg / m3. The results showed that the modulus rupture. Elastic modulus And thickness swelling. It varies with the amount of glue. The nature of the tattoo causes absorption in the material if the density increases the water absorption will decrease. Compared to standard insulation products. The amount of adhesive is 7% of the weight of the material when dry. The density of 800 kg / m 2 is 25 kg / cm2. 140 degree Celsius ruptured modulus and elastic modulus But the thickness of the swelling has not met the criteria. In the next production should be mixed waterproofing in the work.
การพัฒนาและออกแบบผลิตภัณฑ์นาฬิกาตกแต่งบ้านจากขี้เลื่อยไม้เหลือทิ้งในโรงงานอุตสาหกรรมไม้เขตพื้นที่บางโพ กรุงเทพมหานคร
This research is developed and designed wall clocks decorative home From sawdust waste in the factory Bang Pho district in Bangkok. The study was conducted by testing groups of wood manufacturer Bang Pho community the results are as follows. The study found that the criteria of design analysis from the experts were 3.97 at a high level and the satisfaction of the product production was 4.11 at a high level. When evaluating the overall picture the mean score of 4.04 was high level.
การออกแบบและพัฒนาผลิตภัณฑ์ของตกแต่งจากเถาวัลย์เพื่อการออกแบบผลิตภัณฑ์ตกแต่งบ้านสู่การสร้างอาชีพให้เศรษฐกิจชุมชนอย่างยั่งยืนกรณีศึกษา กลุ่มจักสานเถาวัลย์แดงตำบลปากช่อง อำเภอจอมบึงจังหวัดราชบุรี
The main objective of this research is to design and develop products lamps made from vine forhome decoration. The research began by studies the style and quality of vine after that questionnaire interview and observation of the behavior of people in the community were the tools to conduct this research. Rajaburi provinceis the sample and the population was acquired by sampling group. The analysis of the data showed that the average percentage of products used in home decor products such as lamps. The products are used to decorate the home. The house should take into account the nature of the product because it allows the access to nature and the lifetime of the product breaking the car or break easily digested because it is made from natural materials

This research main objective is to design and develop products lamps and wooden plate made from coconut leaves for home decorating items. The research began by studies the style and quality of coconut leaves after that questionnaire interview and observation of the behavior of people in the community were the tools to conduct this research. Samutsongkram District is the sample and the population was acquired by sampling group. The analysis of the data showed that the average percentage of products used in home decor products such as lamps and wooden plate. The products are used to decorate the home. The house should take into account the nature of the product because it allows the access to nature and the lifetime of the product are breaking easily digested because it is made from natural materials.
การปรับปรุงสมบัติทางชีวภาพและสมบัติการละลายของแก้วและแก้วเซรามิกชีวภาพ ในระบบโซเดียมแคลเซียมฟอสเฟตเพื่อนาไปประยุกต์เป็นกระดูกเทียม
This research then has two main objectives. The first objective is to fabrication of bioactive glass ceramics containing BaFe12O19 (BF) crystals has been carried out for the application in hyperthermia treatment. The BaFe12O19 powder was firstly prepared and subsequently mixed with the non-silicate P2O5-CaO-Na2O bioactive glass with various BF concentrations. After that the glass ceramics were produced via a sintering method at 600◦C and their crystal phases were examined by XRD and in vitro test was carried out by soaking in simulated body fluid. Remanence and saturation magnetization and coercivity were deduced from magnetic measurement. It was found that the samples exhibited magnetic behavior which is similar to hard magnetic materials. Our second objective is the effects of sintering temperatures on the physical and bioactivity of SrFe12O19 (SF)-P2O5-CaO-Na2O bioglass ceramics were investigated. XRD results confirmed the existence of the strontium ferrite and calcium phosphate phases. SEM images showed that grain size and hardness were related to density and liquid phase present in the samples. A maximum coercivity value of 3138 Oe was obtained for the bioglass ceramic sintered at 600 ºC. The remanence (Mr) and saturation magnetization (Ms) of the bioglass ceramic sintered at 500 ºC possess the maximum value of 6.35 and 10.64 emu/g respectively. Moreover the apatite was formed on the surface layers of the bioglass ceramics confirming their biocompatibility
