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 l ight-weight precast concrete wall panel product with aerated foam injection technique as core wall. The light-weight precast concrete wall panel product was produced by casting the mortar panels with M3 ratio (proper ratio) set up the steels and injecting the aerated foams. 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 1110.58 kg/m3 of density 9.18 MPa of bending strength and 0.186 watt/m.K of thermal insulation. This light-weight precast concrete wall panel product can use as the thermal insulation wall in building. the developing product can apply to register the petty patent.

The aim of this work was to study the magnetic properties of magnetic glass-ceramics with composition system SiO2-CaO-Na2O-P2O5-BaO-Fe2O3. The magnetic glass–ceramics were prepared by conventional melting at 1300oC for 2 h of the coprecipitation derived starting products and heat treated at different temperatures. The structure and microstructure of the samples were characterized by X-ray diffraction energy dispersive X-ray analysis (EDXA) and scanning electron microscopy. The magnetic measurement showed that the samples which contained barium ferrite exhibited magnetic behavior which is similar to soft magnetic materials. Finally the samples were soaked in simulated body fluid (SBF) for 14 days. The apatite was found to form on the surface layer of glass-ceramics and it increases with the barium ferrite content was increased.

At present a problem found in the soft candy producing process in the food producing department of Company Case Study is time-consuming roller washing process due to an ineffective washing process. A roller is washed one by one from a total of 10 roller (a set) in one machine. As a result the operation rates of other producing processes have been forced to delay. The objective of this research is to resolve the problem found in the process of roller washing by designing a machine for washing a set of roller per time. The research begins from examining design concepts of roller washing machine from patents and the current quantity of water and stream used for washing before conducting design of a new soft candy type roller washer machine. And eventually the efficiency of new roller washer machine is compared with current one. The findings indicate that the newly developed design can reduce washing period from 24.48 minutes/set to 5.56 minutes/set and increase operation time by 18.92 minutes or accounting for 77.28 percent. Meanwhile water quantity used in the process is reduced from 124.82 liters/set to 28.35 liters/set and stream quantity used in the process is also contracted from 0.83 kilogram/hour/set to 0.18 kilogram/hour/set. This reduction can save expenses equal to 28795 baht/year. As the budget for making new roller washer machine is 53000 baht and payback period is only 1.84 year.

The research aimed 1) to develop the product of floral arrangement on pedestal made of Sanoh Hangkai (jointvetch / Aeschynemene Indics L.) with paper mache technique and 2) to study the target group’s satisfaction with floral arrangement on pedestal product made of jointvetch with paper mache technique. The result found that five specialists had a high satisfaction level to the second method of combining jointvetch with tissue from toilet paper. Mean of satisfaction level was 4.00. Fifty people in target group had a high satisfaction level on developing the floral arrangement on pedestal product made of jointvetch with paper mache technique. Mean of satisfaction level was 4.89 4.84 and 4.66. The details were as follows: 1. The specialists satisfied the study of the second method of combining jointvetch with tissue from toilet paper and had the overall comments about its features with the mean at 4.00 (high level). Mean of the material’s tenderness was 4.60 (highest level). The balance of the material was 4.10 (high level). The toughness of the material was 4.06 (high level) and the material’s softness was 3.50 (high level). 2. The satisfaction level of fifty people in target group to the development of floral arrangement on pedestal product made of jointvetch with paper mache technique showed that they satisfied the floral arrangement in rice-grain shaped on pedestal with its highest mean at 4.89. Mean of satisfaction level on the floral arrangement on pedestal with applied Thai style was 4.84 (highest level) followed by the floral arrangement with joss sticks and candles on pedestal which was 4.66 (highest level).

This research is to find a process and psychological interviewing technique that can get an in-depth of consumer Insight. By using a qualitative research method an in-depth interview and non-participant observational technique were used for data collection. The sample group composed of nine participants varied in terms of emotional quotient the ability to adapt and recovery after encountering with critical incidents. Professional in three careers an inquiry official psychologist and marketer interviewed the sample group for an in-depth of consumer insight for security equipment. After that the sample group was interviewed again by the researcher. Findings showed that the interviewing technique of the inquiry official was getting to the point quickly giving pressure and making the interviewee fear by using previous criminal cases. While the interviewing technique of the psychologist was being friendly with the interviewee using assumption that might happen and avoided asking the interviewee’s direct experience the marketer’s interviewing technique was paying more attention on the interviewee’s lifestyle and real-life experience. The research also found that the process to reach an in-depth of the consumer insight began with preparing for the interview introducing the interviewer and building a relationship with the interviewee asking questions investigating the problems before verifying information and planning to solve problems or find the opportunity to sale products. The interview should use friendly language suitable for the interviewee building a relaxing atmosphere and giving an opportunity for the interviewee to express his/her opinion.
