This research 1) to study and analyze the relationship between the context of industrial handicraftsproperties of agricultural waste in community areas and 2) to agricultural waste to find physical properties and the industrial handicrafts for Bantumsua community Phetchaburi province. From primary data it was found the relationship of the community with the context of industrial crafts is a culture of agricultural wisdom from the collection of participatory research data. Found method and test the properties of paper pulp from agricultural waste where banana leaves = A bamboo leaves = B and pineapple leaves = C.Use the formula for quantifying the triangular grid the Trixie Blend Diagram to uses caustic sodium hydroxide 10-15% of dry weight. There are 7 test items 1 formula thin and thickness (a) according to the experimental standard referring to the community product standards plant fiber paper. For testing as follows: 1) standard average weight from the test of paper size 45x85 cm operation number list of the experimental formula test section 1.1) standard weight the overall average is equal to 220 grams/sqm. 1.2) part 2 tear strength which is strong = 3(10a) at 1962 mN the second strength = 1(8a) at 1907 mN and third = 6(13a) at 1467 mN. 1.3) Part 3 the overall moisture content of the paper the experiment found the humidity level is within the normal level at ± 10% which is complete and can be developed into a products or package. 2) Summary of physical properties the color characteristics of the paper according to provide color tones gray-brown and different beautiful suitable for the screen-printing and using large size rubber stamp. Process forming can produce use by semi-automatic heat setting at 140°C at time of 70 seconds per piece is suitable for further expansion to create industrial handicrafts for the community.

Senior and junior systems of each field of study In the Faculty of Textile and Fashion Design The seniors take care of the juniors into the hierarchy of the year. The second year students will conduct the new recruiting activities while the 3rd and 4th year seniors will have the duty to take care of them again. By the style of welcoming new students in each field of study It has a similar style: introducing itself to the juniors looking for the signature pattern the seniors holding the code line singing the format of welcoming the new juniors. Held by the Student Affairs Department It is in accordance with the new welcome activities organized by the university. In which recreation activities are organized under the facade without disconnecting disciplines As a whole group of activities Comments on activities to welcome freshmen I want to change activities every year With duplicate activities Guidelines for solving problems of non-creative recruiting Write a plan to organize a recruiting activity to the Student Affairs Department for consideration.
อิทธิพลของการละเมิดทรัพย์สินทางปัญญาต่อรายได้กลุ่มอุตสาหกรรมดนตรีของไทย
In spite of the copyright law in Thailand where distributing or obtaining a copyrighted work without the permission of the copyright holder is against the law illegal streaming and downloading of music is dramatically increasing. This changing behaviour of consumers has an incredible impact on the music industry as a whole. Our paper analyses the influence of intellectual property infringement on Thailand’s music industry income. The research tools employed in this study are a questionnaire and an in-depth interview to enable analysis. We found that after the evolution of musical technology in the 1990s internet-based music consumption has become significantly more popular and increasingly consumers are streaming sharing and discovering digital music all across the globe including in Thailand. With this new development of digital music the dynamics of the music industry have been affected significantly both in terms of income and number of entrepreneurs. Multiple regression analysis results show that the amount of unauthorized downloading of copyrighted music has a negative effect on Thailand’s music industry income. In contrast the number of property disputes from illegal downloading of copyrighted music has a positive effect on this industry income. The results suggest that entrepreneurs should pay attention to warranty information on products and prices and security of financial transactions in order to encourage consumer authorized online purchasing. In addition law enforcement can help achieve the goal of decreasing online music piracy.
Experimental investigation of a thermosyphon economizer to recover waste heat in the electronics industry
A case study was conducted to design construct and test a thermosiphon economizer for increasing the temperature of feed water by using waste hot water. The simulation of the thermosiphon economizer (heat exchanger) for the establishment of the optimum size was performed using the thermos-economical method. The thermosyphon was made of a total of 80 copper tubes (outside diam.19.05 mm) with evaporative adiabatic and condensation lengths of 300 10 and 300 mm respectively. The working fluid was R-134a filling ratio was 50% by evaporative volume and the thermosiphon was arranged in a staggered form. In testing performance flow rate of the inlet hot water was set at 10 L/min and the controlled inlet temperature of cold water at 25oC. The average flow rate of the cold water was set at 5 7 and 10 L/min respectively. Results showed that the maximum of rate of heat transfer from the condenser section occurred at the flow rate of the cold water of 10 L/min. When test the inlet temperature of hot water of 4555 and 65 o C were used at the inlet volume flow rate of cold water of 10 L/min maximum heat transfer rates from the condenser 4626 8260 and 8790 W were achieved. Moreover the outlet temperature of the cold water which was initially 25o C changed to 311 34 and 37o C respectively. Therefore increasing the outlet feed water temperature reduced energy consumption. The effectiveness of the thermosiphon economizer with the inlet temperatures of hot water of 45 55 and 65o C was 0.47 0.48 and 0.49 respectively.

The objective of this research was to study the satisfactions of students attending Bachelor’s Degree in Home Economics Food Service Industry Program (2-year transfer program in cooperation with enterprises). To compare the satisfaction of teaching and learning genders exhibts and status before admission. To compare the satisfaction of work with the coporation genders exhibts and status before admission. The target population of this study is the students attending Bachelor’s Degree in Home Economics Food Service Industry Program (2- year transfer program in cooperation with enterprises) between 2013-2017 is 139 persons. This study use self-administered questionnaire. The statistical tools used in this study are Percentages Mean Standard Deviation t-test. The analysis of difference between the average satisfactions of teaching and learning not significantly different. The analysis of difference between status before admission satisfactions of teaching and learning not significantly different. The analysis of difference between the average satisfactions of work with the coporation significantly different. In the coordinator of the coaches. Environment and facilities And the benefits and benefits of the establishment. The analysis of difference between status before admission satisfactions of work with the coporation not significantly different. Teaching and Learning Approaches for Bachelor’s Degree in Home Economics Food Service Industry Program are 2 approaches: 1) Solutions for establishment of cooperation of enterprises. The establishment should cooperate with the educational institution. To get students to practice is to help the school. The establishment should cooperate with teachers and teachers. 2) The solution to create the cooperation of the school. Schools should establish relationships with establishments. The school should organize a seminar. And teachers to have a standard level in teaching as well. And develop the curriculum to meet the needs.
