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

การพิมพ์สีครั่งบนผ้าฝ้ายและผ้าพอลิเอสเตอร์โดยไม่ใช้การมอร์แดนท์สำหรับผู้ประกอบการรายย่อย
This research had an aim for studying the printing process of LACCIFER LACCA KERR. (LAC) on cotton and polyester fabric. The Lac dye was extracted by using Sodium hypochlorite solution Sodium hydroxide Hydrogen peroxide and diethyl ether then Acetic acid was used for dye sedimentation. Thenthe printing condition and color fastness to washing crocking and light were examined. The efficiency of solution for extraction process were found Diethyl ether > Sodium hypochlorite solution > Sodium hydroxide > Hydrogen peroxide respectively. The hot air was suitable fixation process for cotton and polyester printing. The cotton fixation was 150oC for 5 minutes it is 11.87 in color strength. And the polyester fabric was fixed at 220oC for 3 minutes the 8.27 color strength was shown. The both of cotton and polyester were printed with Lac dye had the good color fastness to crocking and light and moderate in washing fastness. This study can apply the Lac dye on cotton and polyester fabric by a printing technique without mordanting. Then it can reduce some chemicals in the textile printing industry. This process can applied and transfer for small enterprise for Lac value added appication.

The purposes of this research were to study the obesity reduction behavior of undergraduate students of Rajamangala University of Technology Phra NaKhon and to compare the obesity reducing behavior of the male students and female students. The questionnaire was used as a research tool to collect the data. The samples in this study were 401 students: 176 male and 225 female students. All 401 questionnaires were returned. The collected data were analyzed by using the mean score standard deviation and t-test. The statistical significance was at the .05 level. The findings were as follows. 1. The average body mass index of the majority of the students was at a moderate level which was 22.60. They were in normal shape and not overweight. The male students had an average body mass index of 22.48 and the female students had an average body mass index of 21.60. Both males and females were in normal shape. 2. The students obesity reduction behavior was at a moderate level. 3. There was a significant difference between the male and female students’ obesity reduction behavior at .05 level. It was found that the obesity reduction behavior of the male students was significantly higher than that of the female students at the 0.05 level. Those higher obesity reduction behavior included buying a drug to reduce fat drinking tea or coffee to reduce fat and toxins without consulting a doctor using fiber products certified by a physician using laxatives after dinner without consulting a doctor eating basil seeds before having a meal eating fatburning dietary supplements approved by an expert taking medicine to catch fat from ingested food without consulting a physician eating extracts from garcinnia exercising continuously for 30 minutes exercising more than 3 days in a week losing weight by acupuncture being a customer of hand massage service for weight loss getting a gastric bypass being a customer of weight loss institute with modern equipment having treatment service from body institute with modern equipment wearing a tightening belt or clothes buying reducing fat oil cream and using it without consulting a doctor and getting a liposuction by a specialist. Therefore the obesity reduction behavior of the male students was significantly higher than those of the female students at the 0.05 level.
