การใช้ไม้พฤาษ์และไม้จามจุรีเป็นองค์ประกอบในโครงสร้างไม้
The Research of this paper to propose the usage of Albizia lebbeck (L.) Benth. and Samanea saman Merill are fast-growing commonly found in Thailand. However these species of wood could not be utilized as structural components either economically or safely due to the lack of recommended values for their engineering properties. Therefore the objective of this research was to study their physical and mechanical properties based on statistical data obtained from 11 series of tests in accordance with ASTM 0-143. 0-198 and 0-1037. The number of samples for each test was large enough to ensure 99% interval of confidence. Then goodness-of-fit tests were performed for each set of data to achieve at least 95% level of confidence. Buildings analyzed included residences offices and schools. The buildings were limited to two-storeyed buildings with f1oor-to-f1oor height of 3.00 meters. Given to joists and beams were simply supported. Values of structural reliability were obtained by using accurate methods. Results from testing showed that engineering properties of both species of wood could be represented well by normal distribution. Reliability analyses and designs of wood sections for joists. beams and columns showed that designs of Joists and beams wWe controlled by deflection; whereas those of columns were controlled by buckling. Based on these reasons the governing basic variable for designs of wood sections was the modulus of elasticity (E). If the accepted value of failure probability (P) for serviceability limit states was set to be 10-4. the corresponding upper limit coefficient of variation (COV) of E would be 0.269. Similarty if the accepted value of P for Ultimate limit states was set to be 10~. the corresponding upper limit COY of E would be 0.210. Since COY of E for both species of wood were lower than limit COY mentioned above. they could be used safely as structural components. Proposed design procedures were similar to Working Stress Methods. The only difference from E.I.T. standard was live load. Instead of nominal live loads for residence. office and school as stated In the Municipal law. mean Ifve loads based on data gathered in Thailand were recommended. Wood sections obtalnec from numerical procedures proposed were as large as those obtained from WCCAL Software. Furthennore recommended wood sections and factor of safety (FS) were summarized in appendices. It was also interesting to note that the value of E for compression and tension parallel to grain of both species of wood could be used to predict the corresponding value of E for bending.

This research aims to improve the booth model of OTOP products from Phu Fah Pattana Center Nan Province. To increase marketing channels by distributing products to various locations in order to increase sales to community products. The design must take into account the convenience of rapid assembly and dismantling for a limited time. The characteristics of the booth must be disassembled interesting in looks that reflect the identity of Lanna art. There is a beautiful strong structure to support the weight of the product. The size and proportion are suitable for the usage habits of consumers. Which will help promote products in the community that have higher sales stronger communities. Able to divide the product market in the country and can create marketing channels to other countries. It is a good result for the villagers in the community that will have the guarantee of self-sufficiency and sustainably sufficient lives. From the analysis of the Lanna Wisdom Identity Model there are 4 types of concepts which are The concept of the components of the house GalaeThe concept from the barn Concept of the components of the house Kwan Concept of triangular pattern woven grass. After that it was developed to the stage to interpret the meaning of space in form of booth. And then lead to the design of 4 booths. And conducted a questionnaire to find satisfaction with each type of booths that responded to various usability benefits including satisfaction with the appearance and usage characteristics that responded to the behavior of Most users. Conclusion Booths from the concept of Lanna house components called galae have the highest percentage of satisfaction in 3 aspects which are Percentage of satisfaction with the layout of the booth Percentage satisfaction with workpiece assembly and disassembling storage and transportation Percentage of satisfaction with the perception of Lanna identity. For the satisfaction with the size the proportion of use and the convenience of use the booth from the concept of the components of the house Kwan with the highest rate of percentage satisfaction.

Study guide for improvement development facilities in Public buildings To meet the policy for Universal Design. With the increasing number of people with disabilities and the elderly when combined with the population of children pregnant women or people with disabilities it was found that in the future these populations will be more inclusive. Driving the environment suitable for the disabled and the elderly It is an issue that is widely campaigned around the world. Office of the Promotion and Development of the Quality of Life of Persons with Disabilities The Ministry of Social Development and Human Security has recognized this importance. This will lead to the creation of an environment friendly to people of all ages all ages. Universal Design. It is a universal idea that the United Nations has tried to spread and promote Based on the original concept for people with disabilities to obtain living facilities in buildings and environments according to the Promotion of Non-Handicapping Physical Environment for Disabled Persons project they have been developed respectively Accessible Design Adaptable Design Barrier. Free Design which is finally accepted by the general public The principle of Universal Design that begins with the equality of the user of different ages and abilities. Can be modified Easy to use manually The interpretation is understandable. It has fault tolerances is light and has a size and space for access and use. Study guide for improvement development facilities in Public buildings To meet the policy for Universal Design. Given the importance and origins of this problem the researchers deem it appropriate to study the theoretical concepts to develop a model for improving the environment and facilities in the former public building. For equality and convenience with the assumption that the improvement model can meet the functional benefits for people of all ages who want to use various services As a guideline for creating a prototype building standard for people of all ages For interested people or agencies to apply to their own buildings.
การพัฒนาผลิตภัณฑ์เห็ดหอมอบแห้งด้วยไมโครเวฟร่วมกับลมร้อนแบบสายพานลำเลียง
Drying an agricultural product with hot air (HA) method causes a long drying time and results in high specific drying energy consumption (SEC). The dried product has high shrinkage percentage and low rehydration. Therefore this research aims to develop dried shiitake mushroom using belt-conveyor combined microwave-hot air drying method (MHB). The shiitake mushroom was dried by MHB at microwave power of 300 W 400 W 500 W and 600 W and air temperature of 65 oC with air velocity of 0.3 m/s and recycled air of 80% and by the HA drying method at air temperature of 65 oC. The samples were dried until their final moisture content less than 11.1% dry basis. The drying kinetics SEC of drying process and quality of dried shiitake mushroom were evaluated. The quality of dried product was considered in terms of color shrinkage rehydration texture water activity and microstructure. The results showed that the shiitake mushroom drying using MHB gave higher drying rate than that of HA drying method leading to short drying time and resulting in low SEC. The drying rate of un-blanched shiitake mushroom was higher than that of blanched shiitake mushroom. Dried shiitake mushroom from MHB drying gave lower values in shrinkage percentages and hardness but higher rehydration and larger pore size than that dried by HA drying. However the color values (L* +a* and +b*) of dried shiitake mushroom in all cases were not significantly different. Meanwhile dried shiitake mushroom from un-blanched case gave lower values in shrinkage percentage and hardness but higher values in all colors and rehydration and larger pore size than those of blanched case.
