The cross-cultural customer experience and the service environment were two of the most important aspects of retailing that should be prioritized particularly in pharmacy shops. This research investigated the retail experience at the pharmacy store from the perspectives of people from a variety of diverse backgrounds and different geographical locations. The interview was planned and performed by the researcher using a semi-structured format. Participants were recruited from a variety of community-based pharmaceutical shop during the pandemic in the Bangkok areas. The researcher applied convenience sample with the assistance of the owner of the pharmaceutical shop. The analysis of the data was transcribed verbatim and analyzed for key themes via manual inductive coding and constant comparison. The research participants shared their personal experiences with purchasing drugs and associated items during the pandemic. They were also exposed to the stores atmosphere and sanitary environment. Misappropriation of retail space might be caused by dissatisfaction with the shopping experience. A variety of behavioral strategies that improved the retail experience such as creating a dedicated section in the shop for relevant items or updating the in-store environment may help improve the retail experience for customers. The authors provided suggestions for how retailers might use their newly acquired knowledge about consumer behavior. Each of these themes also offered the possibility of further investigation in the future.

HV power distribution system circuit breaker are important devices in substations. Such as Malfunction or deterioration of equipment with in the substation will directing impact on the stability of the power distribution system and affect the reliability of the system. In addition this means that it is necessary to assess the actual condition of the proper condition-based operation and maintenance. Thus this thesis presents condition assessment procedure for equipment by using technical information visual inspection by Weighted Scoring Method. Weighting technique is used to determine important weight testing methods of devices by using Analytic Hierarchy Process (AHP). Testing methods for circuit breaker are such as visual inspection contact timing test. Scoring technique is divided into 1-3 levels by classifying on actual evaluate equipment consisting of consisting of good moderate bad. This thesis proposes a software development in order to organize the database and calculate the analysis of the condition of equipment in 5 HV substations. The evaluation results will be divided into 3 levels good medium and bad condition. According to the evaluation level the maintenance types are separated into 1) regular maintenance 2) increase the frequency of maintenance and monitoring of the test 3) equipment must be improved urgently. Finally abnormal incidents of equipment and cost of HV equipment maintenance can be reduced in effective way.

Man Lueat (Dioscorea alata) flour is a biopolymer material that can be formed into an edible film. It can be contacted directly with food consumed and naturally biodegraded. The aims of this research were to study the effect of physicochemical mechanical and thermal properties of edible film from Man Lueat flour. The film forming solution was prepared by Man Lueat flour at 4% w/w. The glycerol was used as a plasticizer. It was studied at 3 different levels; 30 40 and 50% w/w of Man Lueat flour. The film forming solutions were formed using the solution casting method and dried at 50 °C for 16 h. Results showed that the glycerol content at different levels of the edible film from Man Lueat flour had no effect on the thickness color transparency and elongation at break. However the moisture content water solubility swelling property and water vapor permeability of the film tended to increase when increasing the glycerol content. In contrast the Young’s modulus and tensile strength of films tended to decrease significantly when the glycerol content increased. Thermal properties were found that decomposition temperature of films occurred 2 stage; the first stage occurs between 50 to 130 ° C and the second stage occurs between 263 to 315 ° C. The analysis of FT-IR showed that the different levels of glycerol affected the structure of the film (3278 cm-1). Therefore the edible film from Man Lueat flour can be applied as a food packaging material to protect the quality of food products.

The research proposes to find an optimum ratio of solvent based white ink for flexible package development by studying and comparing the qualification of white ink on plastic film. The process consists of separating the white ink ratio into 5 sampling group ratios and then examining ink quality by its’ solid content and grinding. The viscosity is controlled in 16 second and then measured by Zahn’s cup no. 3. The sampling ink is printed and inspected printing quality by (1) E*ab and opacity on polyethylene terephthalate (PET) plastic film and oriented polypropylene (OPP) and (2) bond strength by extrusion. The result shows that sampling ink with hardener substances and ink and varnish ratio is at 90:10 certifies in all aspects compare with other sample. Indicators are the net present value (NPV) Benefit/Cost Ratio: B/C Ratio Pay Back Period and internal rate of return of investment (IRR). The Feasibility Study found that the projects are the net present value (NPV) of 5053593 baht payback period of 1 year 8 month and rate of return on investment (IRR) was 54.79 %. B/C ratio = 1.25

This research aimed to experimentally study of solar panel efficiency with water cooling. Three mono-crystalline solar panels with the capacity of 80 W (for each panel) were used for this test. The first panel was a solar panel without water cooling. The second panel was a panel with water spray cooling. The last panel was a solar panel with water drop cooling. The cooling water flow rate was varied to 50 75 and 100 LPH. From the test it was found that the temperatures of all solar panels had the similar trends. The solar panel efficiency decreased when the temperature of solar panel increases. The solar panel efficiency increased when the cooling water flow rate was increased for both of water spray cooling and water drop cooling. For all water cooling flow rates the water spray cooling solar panel performed higher efficiency than water drop cooling solar panel. The highest solar panel efficiency in this test occurred when the water spray cooling flow rate of 100 LPH.
