Direct selling business has plays a vital role for generating national revenue towards Thailand economic for several decades. Particularly during last past decade direct selling business has been generating in the diversity size involved large medium and small business unites. This business attempts to win in national consumption markets by using the form of direct selling system for distribute of products and increase sale volume. Thus the objective of the research is attempts to study the quality of direct sales in particular supplement food products through the lens of independent distributor. The results of the study will used for developing of direct sale company service quality efficiency. Five point Likert scale and closed end questionnaires were used for collecting data from executives directors of 12 direct sale companies and 400 independent distributors. The data were interpreting by using percentage (%) Mean (x) and standard deviation (S.D). The inferential statistics represented by t - test and F-test. The research finding indicated that direct sales service quality management is the important factor that can be contributing business success. Considering in detail found that the relationship between service provider (direct sale company) and service receiver (independent distributor agency customer) have a most significantly important in among other service dimensions. Look through the company size dimension the large size company has pay attention on every service quality details. Despite the overall picture of direct sale companies in Thailand have providing promotional services to the independent distributor in order to meets the standards of the direct sale association development of Thailand. Addition the objective of this association is for enhance direct selling business standard simultaneously generated the confident of new comer businessmen and customer in direct sale business network. Hence promoting business development plan is requiring the expertise person who have been in this particular area of business to supervise of business outline under the framework of direct sale association development of Thailand Key words : The direct selling business

The purposes of this research were (1) to study and (2) to rank the needs of RMUTP environment management on undergraduate students’ learning development as well as (3) to present a proposed guideline to improve RMUTP environment. 343 students enrolling in the first semester of the academic year 2015 were selected with simple random sampling. The research tool was questionnaire. The data were analyzed through percentage (%) mean ( ) standard deviation (S.D) t-test modified priority needs index: PNI modified and content analysis. The results demonstrated that: (1) The overall mean scores of the reality and expectation of RMUTP environment on students’ learning are statistically different at 0.01. (2) The physical environment needs for supporting students’ quality of life was ranked the first. The second was university facilities to enhance their learning and the third was help and information service. The curriculum management was ranked the fourth. The last one was instructors. (3) A students’ proposed guideline: 3.1 As for physical environment needs for supporting students’ quality of life the highest was more relaxing space. 3.2 As for university facilities to enhance their learning the highest was that learning equipments should be adequate for them. 3.3 As for help and information service public relation and university information for students should be improved at a high level. 3.4 As for curriculum management the study suggested students’ needs for curriculum development to meet current employment demand and to implement effectively at the workplaces. 3.5 As for instructors the highest rank was that instructors ought to understand and listen to students’ needs. They should let students express their opinions.

The objectives of this research are to study the production to find the proper ratio to test the physical mechanical properties and thermal conductivity to suggest the implementation and to transfer the technology of light-weight precast concrete wall panel product with adding high density foam sheet. The light-weight precast concrete wall panel product was produced by covering the foam sheet with steel pouring the mortar (M3 ratio which was proper ratio) and curing the light-weight precast concrete wall panel product. From the testing results followed the TIS.2226-2548 and TIS.878- 2537 the general characteristic of light-weight precast concrete wall panel product was perfect. The properties of light-weight precast concrete wall panel product include 17.81 MPa of compressive strength no bending when installed in common behavior 11.38% of water absorption passed in type1 of hardness and impact test 956.03 kg/m3 of density 9.18 MPa of bending strength and 0.170 watt/m.K of thermal insulation. This light-weight precast concrete wall panel product can use as the thermal insulation wall in building. Moreover the developing product can apply to register the petty patent.

This research has objectives to study the production to find the proper size of steel wire mesh to test the properties and to study the implementation of high strength and thermal insulation cement-bonded fiberboard from coconut meal corncob fibers and steel wire mesh. The mixture ratio of cement-bonded fiberboard included Portland cement type1: sand: coconut meal fiber: corncob fiber: water: calcium chloride equal to 1: 0.2: 0.0125: 0.0375: 0.3: 0.03 by weight and 5 different sizes of steel wire mesh were reinforced. Casted by compression and sharking machine. Tested the properties follow the TIS.878-2537. From the results 1 mm of diameter and 1” of gab of steel wire mesh (? 1 mm # 1”) was the proper size to reinforce the cement-bonded fiberboard to get highest bending strength. Moreover this cement-bonded fiberboard can pass the required standard. The high strength and thermal insulation cement-bonded fiberboard from coconut meal corncob fibers and steel wire mesh has the possibility to construction as exterior building wall.

This research aims to study the usage pumice rock fragments to develop paving block product for community. The mixture ratios of Portland cement type1: sand: quarry dust: pumice rock fragments: water that there are 6 ratios. The paving block samples are casted in 30 x 30 x 5 centimeter in dimension. The paving block sample testing follows the TIS 378-2531 on concrete flooring tiles. From the experiment bending strength and thermal conductivity of paving blocks with high quantity of pumice rock fragments are lower than paving blocks with low quantity of pumice rock fragments but the water absorption of paving blocks with high quantity of pumice rock fragments are higher. However all of pumice rock fragments paving block samples with lower than 1: 2: 2.4: 0.6: 0.6 of ratio can pass the standard and the surface temperature is lower than other covering materials about 2 degree Celsius.
