This paper presents the packaging design of the straw material replacement process. For environmentally - friendly products Product Case Studies MAZMOIZELLE Shop Due to the awareness of the environmental problems that affect the lives of all living. The weather is changing. One solution is Eco-design (Economic & Ecological Design) which plays an important role in the production process. Environmental concepts are added to the design process to develop environmentally friendly designs. The sample consisted of the research instruments used in this research were 80 persons. Pre-design questionnaire the questionnaire evaluates the satisfaction of the packaging structure for the environment. Data were analyzed using percentage analysis. The results are evaluated by experts and experts in three aspects: packaging graphic and marketing. The instruments used in the research were questionnaires and satisfaction questionnaires. The results showed that. 89% of respondents agreed to use recycled materials for packaging. The evaluators have a need for environmentally friendly packaging by developing robust packaging. Product Protection And graphics on the beautiful packaging. This shows that packaging is environmentally friendly. And the evaluator needs the uniqueness of the product for the environment. The results of the study concluded that the design of the structure and graphics on the packaging for the environmental products of the five structures from the MAZMOIZELLE product include the packaging for the camera strap. Sack bag Packaging for documents A5 packaging for wallets and notebook bag packaging very good. Packaging can protect the product well and easy to use. Graphic design on packaging that represents a unique identity for environmental conservation. And the results of the replacement test with rice straw mixed grain. Seeds can be grown at a rate of 70% which is good.
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 purpose of this research was to 1) study the profile of physical fitness of the undergraduate students of the Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. 2) study the factors contributing to physical fitness of the undergraduate students of the Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. 3) study the guidelines in building physical fitness of the undergraduate students of the Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. The research focused on the quantitative aspects of sport fitness by using equipment to test physical fitness and the questionnaire to measure the factors contributing to physical fitness and the guideline supporting the physical fitness. The questionnaire approved by the experts was used to collect data from 215 students who had been tested for physical fitness. To answer the research questions the data were statistically analyzed and processed using computer program for frequency percentage mean and standard deviation. The results of the study were as follows: 1) a good level of physical fitness of the undergraduate students was sitting and bending forward. An average level of physical fitness included standing & sitting in 60 seconds per one time long jump and 50 meter run. A low level of physical fitness was a 30-second push-up. 2) the factors contributing to physical fitness of the students included 2.1) interest 2.2) physical readiness 2.3) equipment 2.4) need for exercise and 2.5) sport outfits and 3) the guidelines for supporting physical fitness of the students included 3.1) fast walking 3.2) cycling 3.3) swimming and 3.4) running.
