he monthly rainfall forecasts are very important in Thailand because the most of people has a career in agriculture. The monthly rainfall forecasts can be analyzed for manage water resources. In addition the monthly rainfall forecasting is used to manage water for consume in Thailand. This research is forecasting monthly rainfall under the global warming using a multilayer neural network. It is a network with one hidden layer. The data from the Meteorological Department is use. Imported variables include temperature humidity and wind. The forecast from January to December 2018. The mean square error (MSE) to measure forecasting accurate and found that the value is suitable error (10.25). The neural network can provide accurate monthly rainfall forecasts from January to December. It was found that the southern region had the highest rainfall and the eastern region northeastern region northern region central and western regions respectively. Therefore neural networks can be forecast rainfall accurately and efficiently. It can be used to analyze and manage water resources effective.

Thailand is one of the few countries in the world that provides the whole value chain of the textile industry with over 4700 local textile producers and 800000 to one million workers making this industry the second-most important employment sector. In 2016 the industry’s export revenue was valued at almost USD 7 billion contributing to over 3% of total exports. The Association of Southeast Asian Nations (ASEAN) is the biggest international market for Thailand clothing export (23%) and expected to become the worlds fourth largest market by 2030. However Thai cloth entrepreneurs are facing major problems that demand attention including labour costs new design and product development and in particular online marketing. The Thai fashion and textile industries should define a clear strategic move through integrating textile with fashion with a view “toward sustainable creative industries with strong soft power”. The purpose of this study is to analyse competitiveness of Thai cloth entrepreneurs in relation to online management and integrated marketing communications (IMC) in the ASEAN market. The research instrument involves a descriptive cross-sectional mixed-method study in Thailand. For quantitative data 60 cloth entrepreneurs are invited to complete a questionnaire before and after our “online management and IMC” training programme and a qualitative in-depth interview study is conducted with 10 cloth entrepreneurs. The 2017 survey returned 100% participation with general agreement that a website and Facebook are the most important IMC tools for online marketing in the ASEAN market. Before training the participants had knowledge and skills regarding the ASEAN Free Trade Area (AFTA) online communication and social media tools in intermediate level while they had less knowledge and skills concerning social media web design and online gallery. After training the statistics show an increase in entrepreneurs’ level for all knowledge and skills. Furthermore the findings from in-depth interviews show that with regard to entrepreneurial competitiveness in relation to the ability of online management and IMC there is a requirement for further training and government support. In addition the 10 cloth entrepreneurs agree that time management and quality of product and service control are very important for online business.

The purpose of this research is to study the construction safety measure for working at height. The safety measure for working at height in this research is developed by referring to the Ministerial Regulations prescribing the standard for administration and management of occupational safety health and environment for construction work 2008. The average of safety is low in five high rise construction projects in Bangkok metropolitan. So all parties involved in contractors need to focus on safety measure for working at height.

The purpose of this research was to study personal factors and service marketing mix factors affecting consumer satisfaction towards co-working space in Bangkok. This research combined a research methodology between quantitative and qualitative research with tools for data collection including survey and in-depth interviews. Quantitative data was obtained from a survey of 400 samples using coworking space in Bangkok. Qualitative data was obtained by the use of in-depth interview with consumer manager and coworking space specialist. The results showed that the personal factors affecting consumer satisfaction towards coworking space in Bangkok were mainly 1) ages between 25 - 30 years old at 44.25% 2) private employees at 53.00% 3) average monthly salary 20001 to 30000 baht at 42.75% and 4) usage frequency 1 - 2 times per week at 37.25%. Service marketing mix factors affecting consumer satisfaction towards coworking space in Bangkok were 1) product (mean 4.22) and 2) physical evidence and presentation (mean 4.37) at the .05 statistical significance level.

The objective of this study was to investigate mechanical properties namely hardness of cemented tungsten carbide workpieces which were the mixture of 75 wt% tungsten carbide (WC) and 8 wt% -10 wt% cobalt (Co) as the binder . Other composites used included 0.5 wt% tantalum carbide (Tac) 14 wt% - 17 wt% titanium carbide (TiC) and 0.5 wt% - 1 wt% niobium carbide (NbC). The workpieces were then formed and sintered at 1450 °C. After the forming and sintering processes were completed the workpieces with different composites were obtained. The results showed that there were the differences in green density and hardness between recycled tungsten carbide powder and commercial tungsten carbide powder workpieces. Different particle characteristics and chemical components of tungsten carbide powder resulted in poor flow between the particles affecting density and hardness. Besides the compression of the metal powder before sintering could reduce the porosity because low porosity led to less shrinkage during sintering as shrinkage during sintering varies with the workpiece density after forming
