The special project study aims to create transformative jewellery for women from Lanna-style glass as well as to examine the satisfaction of the target groups on the jewellery. The different three design of the transformative jewellery were sketched based on the review information. The jewellery can be split into smaller pieces which are a necklace earrings and a brooch. Then a favourite design was considered by five experts. Some recommendations for better design were also provided. After that the jewellery was created according to the selected sketching. The satisfactions on the jewellery were collected from two groups of people; 1) twenty-five jewellery entrepreneurs and 2) twenty-five working women aged 18-60 years (Ministry of Labor 2019). The total data of fifty samples were analysed by using frequency percentage and mean. The results showed as following. Three of the five experts chose the design number three as the model was interesting. The necklace earrings and brooch can be detached to suit an outfit perfectly. The experts preferred the transformation by studs and hooks. Furthermore the colour tones are harmonious and can draw the human perception resulting in a variety application on an outfit. The satisfaction of two groups of people; 1) jewellery entrepreneurs 2) working women aged 18-60 years; were examined. It was found that for the style of the jewellery both groups were satisfied with the creativity of the jewellery design at the highest level the satisfaction means were 4.80 and 4.68 respectively. In terms of materials the entrepreneurs were satisfied with the novelty the strength and durability and the safety of materials at the highest level having the same means of 4.36. The working women were satisfied with the suitability of the materials at the highest level with the mean of 4.52. In terms of utility both groups had the satisfaction of wearing to parties at the highest level with the mean of 4.56 and 4.44 respectively. Regarding the price the entrepreneurs were satisfied with the price of 3999 baht at the highest level with the mean of 4.48. Also the working women were satisfied with the price of 2999 baht at a high level with the mean of 4.20. For the place of distribution both groups had the satisfaction of the jewellery stores at the highest level with the mean of 4.96 and 4.52 respectively.

The special project on Transformative Tray with Pedestal from Tinted Glass Design by Lego Technique has the objectives to study the design and procedure of the transformative tray with pedestal from tinted glass design by lego technique and to investigate the satisfaction of the target group towards the transformative tray with pedestal from tinted glass design by lego technique. The researchers conducted the study and collected the data related to a sketch design of the transformative tray with pedestal from tinted glass design by lego technique which can be modified into 3 ways a rice funnel tray a holy-water bowl tray and monks alms bowl tray. 5 experts will consider the structure of three trays and choose the lotus petal pattern a tray and the color of the lotus petals that the experts like and it must be most suitable. They also give a suggestion to design the transformative tray with pedestal from tinted glass design by lego technique. After that the suggestions were used to survey the satisfaction of the target groups 25 students from Home Economics Business Administration Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon and 25 public people in 5 aspects a product materials utility price and distribution area. Then bring the data into the analysis by using frequency percentage and mean. The result of the analysis shows as follows. From the design and procedure of the transformative tray with pedestal from tinted glass design by lego technique it was found that most experts agree that all three tray are suitable size and proportions for the transformative tray with pedestal from tinted glass design by lego technique. A wooden tray should be used because the lotus petals are plump and delicate. Because the wood tray is strong and the tray should be embedded with glass for a match the colors should be contrasting colors to make the pattern stand out. There should not have additional decoration because the work is outstanding with the pattern of tinted glass. Suggestions for delicate work should be planned and should have a smooth glazing. Satisfaction of the target groups towards the transformative tray with pedestalfrom tinted glass design by lego technique: Satisfaction of 25 students from Home Economics Business Administration Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon shows that the respondents were satisfied in the product with the neatness and the beauty of the products with an average of 4.48 at the highest level. Regarding the materials respondents were satisfied with the suitability of the materials used and the strength and durability of materials having an average of 4.48 at the highest level. Regarding the utility respondents were satisfied to use a product as a sacrifice item and as a learning media having the average of 4.56 at the highest level. Regarding the price the respondents were satisfied with the price of 10750 baht with an average of 4.32 at the highest level. Regarding of distribution the respondents were Satisfied in the Buddhist alms shop having an average of 4.60 at the highest level. Satisfaction of 25 public people shows that the respondents were satisfied in the product with the neatness and the beauty of the products with an average of 4.36 at the highest level. Regarding the materials respondents were satisfied with the suitability of the materials used having an average of 4.40 at the highest level. Regarding the utility respondents were satisfied to use a product as a sacrifice item having the average of 4.40 at the highest level. Regarding the price the respondents were satisfied with the price of 12300 baht with an average of 4.24 at the highest level. Regarding of distribution the respondents were Satisfied in the online shop having an average of 4.08 at the highest level.

The aim of this work was to fabrication of Hydroxyapatite Glass-ceramic by adding ZrO2 for Dental Application. The glasses were prepared by conventional melting of the coprecipitation derived starting products and heat treated at different temperatures. The structure mechanical properties and microstructure of the samples were characterized by X-ray diffraction Vicker hardness energy dispersive X-ray analysis (EDXA) and scanning electron microscopy. The data showed that the samples with condition Li1-1450 and heated treatment at 830 C having high strength and proper crystallinity showed good translucency which comparable with that of the sample from factory. XRD analysis revealed XRD analysis revealed that the peak corresponds to the crystallization of Li2SiO3 SiO2or Li6SiO8which are important phases have effect to increasing the mechanical properties of samples.

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
