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

The purposes of this research were to Design for Furniture Woven from Sedge Paeng Group Sub District Paeng Amphoe Kosum Phisai Mahasarakham. Sample group in research is foreign tourists 50 people and Local people 50 people. Wants to buy processed of products processed Furniture Woven from Sedge Paeng Group Sub District Paeng Amphoe Kosum Phisai Mahasarakham. Tool used in research is a questionnaire want side different of the target audience have confidence equal to .964 statistical analysis was performed by percentage. Average mode and questionnaire to evaluate satisfaction in the field of use and in marketing processed products from Furniture Woven from Sedge Paeng in the process evaluation choice and in the evaluation process compare with the original souvenirs by the questionnaire 2 copies have confidence equal to .830 and .784 respectively. Statistical analysis was performed by means of percentage mean and test the hypothesis with the t-test statistic type Dependent Sample. The research concludes that. 1. The processed product design for furniture woven from reeds method 1 suitable for buying relatives brethren. Method 2 Method 3 suitable for buying boss adults and Method 2 suitable for buying in the family. 2. Select target group the processed product design for furniture woven from reeds in method 3. 3. The target group is satisfied in processed products design for furniture woven from reeds the new model is more than the original model on all sides. Statistically significant at the .05 level vendors are more satisfied than the original model in almost every aspect and processed products design for furniture woven from reeds powerful new applications rather than processed products woven from reeds original.

This study was to 1) investigate the using behavior on the road accessories in the park and 2) analyze the design guideline for the product consistent with the use of leisure space in passive way 3) synthesize the design guideline to for the product consistent with the use of leisure space in passive way to response city life and 4) to find solutions to the problems of sustainable use of public space. The conclusion of the data analysis by using questionnaires from residents in the sample area found that; 1) Respondents were 130 men or 43.4% and 170 women or 56.6% 2) the highest average score was from 94 respondents age 31-40 years old or 31.4% 78 respondents age 21-30 years old or 26% 3) 116 respondents or 38.7% were company staffs with the highest score followed with 89 students or 29.7 and 4) 4 respondents or 8.89% who have live less than 20 years 14 respondents or 13.11% age 21-30 years old 12 respondents or 26.67% age 31-40 years old and 15 respondents or 33.33% for age 41 years old up 5) 98 respondents or 32.6% spend time in the park 1-2 times a week 94 respondents or 31.3% 6) 142 respondents or 47.3% for the reason of relaxing in the park- quiet and followed with easy to access 121 respondents or 40.3% and lastly 7) the activities in the park is relaxing 141 respondents or 47%.For design the research design from data analysis and experts. It shows that 1) the main structure is steel tube and nylon product and 2) concept design was from nest and cradle. The feature of the product is like the weaverbirdnest and the cradle gives personal area.
