The objective of this research is to increase the tool life of trimming process by surface coating technology. The procedure of this research consists of two sections. In the first section the friction coefficient was investigated with the ball on disk technique by using a tribometer. Steel ball was produced from cold work tool steel grade SKD11 (JIS) hardened to 60±2 HRC. Two types of surface coating namely AlCrN and TiAlN were conducted by PVD technique. Disk material used in this experiment was made by stainless steel JIS; SUS 304 of 2 mm thickness. For the second section the wear tests of trimming die were performed by using flat punch and inclined punch 45 degrees without surface coating as well as the inclined punch 45 degrees coated with AlCrN and TiAlN (PVD). Workpiece material used for the wear test was stainless steel JIS; SUS 304 of 2 mm thickness. Additionally the finite element analysis was carried out for explanation the deformation of the workpiece during trimming operation. Although the friction coefficient of the surface coating was higher than non-coating it could be extended the tool life ostensibly. As the result of FEM the inclined punch 45 degrees could be generated the long sheared surface more than the flat punch. This is due to the internal stress of workpiece that did not connect from the punch to the die so the crack propagation would be delayed. The inclined punch 45 degrees coated TiAlN has a highly durable which can be used up to 5000 strokes.

In conducting the research on Material Science two composite materials ultra high molecular weight polyethylene (UHMWPE) powder and aluminum oxide (Al2O3) powder were formulated by hot compression molding process. The formulated materials demonstrated good mechanical properties and high wear resistance properties. Based on the studies the Al2O3 grade selected was Al2O3 HTM 30 harboring mixed uneven powder particle sizes ranging from 2 to 5 microns (μm) and selected proportion of Al2O3 alloy mixed for improving mechanical and wear resistance properties of the UHMWPE composite material was the UHMWPE+Al2O3 HTM 30 at a ratio of 95:5%. When considering both material properties and cost effectiveness in the impact test 2-5 μm Al2O3 HTM carried the higher impact strength than other aluminum oxide grades with the values up to 586.8 J/m at a ratio of 5% aluminum oxide. The hardness test of the 2-5 μm UHMWPE+ Al2O3 HTM delivered the hardness at 58.8 using the standard durometer. The tensile test values consisted of Yield Strength Ultimate Tensile Strength Breaking Strength Elongation at Break and Modulus of elasticity equal to 20.52 MPa 29.96 MPa 22.83 MPa 265.8% and 784.46 MPa respectively.

Talad Noi Community is an ancient Chinese community found since the beginning of Rattanakosin. There are many important historical values in this area but also there are still many problems caused from the prosperity of the urban community leading to the process of swallowing up until disappeared from the development of big cities like all old towns. Therefore these solutions can to be promoted by utilizing the applications to promote minor market community activities. To the development of applications it can be concluded that the overall system users both general users and administrators are at a very good level. In terms of the ability of various systems administrators are satisfied with the user manual of the system that is clear and easy to understand as much as possible. As for working according to various functions in the system administrators are satisfied with setting the password using check and the satisfaction system of users. In addition general users satisfy with the overall systems as their convenience and speed.

This research aims to study the acceptance of financial transactions among the elderly people in Bangkok metropolitan classified by personal factors the features of mobile banking applications and the attitudes of using services of mobile banking applications that related to the acceptance of financial transactions of the elderly people in Bangkok metropolitan. The samples used in this research were 400 elderly people living in Bangkok metropolitan. Data were analyzed using descriptive statistics namely frequency percentage mean and standard deviation; and inferential statistics namely independent sample t-test One-Way ANOVA and Pearson’s correlation coefficient. The results were found that the overall acceptance of mobile banking applications was at a high level and when considering the acceptance in sub levels the intention to use mobile banking continuously in both the present and the future was accepted in the highest score followed by suggesting others to use the mobile banking application. The hypothesis test revealed that: 1) the differences of age educational level income and experience of using mobile banking applications differently affect the level of acceptance on using a financial transaction on mobile banking applications: 2) the features of mobile banking application in the gained benefits the ease of features in mobile banking applications and confidence are positively correlated with the overall acceptance of the usage of mobile banking applications: 3) the attitudes towards the use of knowledge-based mobile banking applications value/social influence and service usage behavior are positively correlated with the acceptance of mobile banking applications in both overall and sub-issues. For suggestion of further research the development of mobile banking applications enabling more elderly people to turn to use the service may need to consider different sample groups such as various educational levels. The features of the mobile banking application must be beneficial to the elderly people because it was the most correlated factor in building confidence of elderly people deciding to use mobile banking applications. In terms of attitude the Mobile Banking Application service providers need to further study the elderly people behavior in using mobile banking applications to improve the services to be the most appropriate services. Related agencies and government agencies can use the research results as a guideline for policymaking or strategic planning in designing suitable government services for the elderly people to receive better welfare that supports the entry into Thailands aging society.

The development of the application to support tourism in Samut Songkhram province aims to develop accommodation search applications. Hotels attractions OTOP products to promote the distribution of OTOP products in tourist attractions to assess satisfaction with developed applications using AppSheet Google Sheet Google Map and other open-source software to develop and surveys to collect data assess satisfaction with built applications. Perform statistical data analysis Percentage average standard deviation The results showed that the application to support tourism in Samut Songkhram province Help promote comprehensive tourism in Samut Songkhram Province Enhances the distribution channels of OTOP products in tourist attractions. The results of the satisfaction assessment from 50 users in the sample system showed that users were satisfied with the application to support tourism in Samut Songkhram province with an average of 4.41 standard deviations of 0.06. Can be used.
