The objective of this research is to study how rotation speeds affect mechanical properties with friction welding between semi-solid metal 7075 aluminum alloys and semi-solid metal 356 aluminum alloys. The factor of interest is rotation speeds with different conditions at 800 1000 1200 1400 and 1600 rpm respectively. 1.8 millimeter for burn of length 30 seconds for welding time and clockwise rotation are set as a control constant condition for the entire experiment. After friction welding we found that different rotation speeds significantly affected mechanical properties of these alloys. At rotation speed 1400 rpm the maximum tensile strength is 122.24 MPa and the maximum hardness in welded zone is 140.5 HV. The microstructure size is 2.250 µm long and 2.144 µm wide. Its size in welded zone is practically small because of friction force. Moreover this friction force causes the mixture of MgZn2 and Mg2Si in welded zone.

This research is a qualitative research. Aim to study how to handle an effective water management. Case study: Muang Samutsakorn District Samutsakorn Province. Either before implementation or during the process and post implementation after the project has been achieved. Sampling groups are agencies involved representing the effective water management resulting in helping Muang Samutsakorn Samutsakorn Province survived from the B.E.2554 mega flood crisis. Consist of Director Head of Engineering Water Delivery and Maintenance Project Phasi Charoen Irrigation Office 11. The research results are summarized below. 1. Pre-implementation Preparation by dredging various gutter in the canals removing all water obstacles installing more mobile water pumps at main pumping stations. Establishing working committee for flood solving and preventing Center. Furthermore check the readiness of tools to be used. 2. During the process Start running the operation center to solve the crisis and closely supervise the action plans. Co-ordinate between Nakhon Pathom Province Samutsakorn Province Bangkok Metropolitan Administration and Department of irrigation in administration of water management. Integrate all parties concerned like government and private sectors. 3. Post-implementation Continuously publicize the outcome. Repair the sewage and drainage system which are damaged from use. Make further sustainable plan for drainage system.

The objectives of this research are; 1) To study the food consumption behavior of metabolic syndrome risk group PhaiNgam Health Promotion Hospital Khok Sung District Sakaeo Province; 2) To study variables affecting food consumption behavior of metabolic syndrome risk group; 3) Propose alteration food consumption behavior of metabolicsyndrome risk group to executive of PhaiNgam Health Promotion Hospital. A group of 190 Metabolic syndrome risk group was sample with purposive sampling. Data were gathered through questionnaire. Data analysis used the number percentage mean standard deviation and Chi-square test (𝜒2). The food consumption behavior of the group was at a moderate level good. Variables affecting food consumption behavior. Found that body mass index waistnumber of children monthly income exertion or physical activity affect food consumption behavior of the group at the statistical significance of 0.05. Propose alteration foodcunsumption behavior. 1) Using red orange green 3 feeding model. 2) Establishing the principle of eating to control energy. 3) Collaboration with public health officials group activities centered around the relationship achieved a rong. For to executive ofPhaiNgam Health Promotion Hospital.

towards the bakery and the decisive factors affecting the selection of its products around the area of Mahidol University Phutthamonthon District Nakhon Pathom Province. The sample are 400 people and the research instrument was the rating-scale questionnaire administered to investigate the expectation factors and consumer demand towards the bakery and the decisive factors affecting the selection of its products. The statistical devices used to analyze all of the data from the questionnaire were the percentage mean and standard deviation. The results from the expectation factors and consumer demand towards the bakery showed thatthe sample like to have the bakery decorated in a vintage style. The customer service include having some relaxing and eating areas and takeaway. The bakery hours are 09.00 am – 09.00 pm. and it should close on Wednesdays. The price of the products are between 101 - 200 baht. Furthermore tea coffee chocolate cocoa fresh milk should be included in the bakery. From the decisive factors affecting the purchase of the bakery products it revealed that the sample prefers eating or buying cake most. Theconsuming frequency is once a week and the products are bought for only the consumption during 3 pm. – 6 pm. About the product the quality of the bakery must be fresh. The price is fair for the value of the product. The location of the bakery should be accessible and in the community. About the service the waiters or waitresses must greet and welcome customers politely and happily. Moreover the sale promotion is having the members get a discount

Weather predictions by an atmospheric model are determined by the uncertainties in the initial condition and the imperfection of the model. It is difficult to provide accurate weather prediction. The efficiency of weather predictions model is obtained from the analyses of Lyapunov exponent. In addition the predictability measurements is applied from Lyapunov exponent are finite size Lyapunov exponent finite time Lyapunov exponent local Lyapunov exponent together with a new method called supremum Lyapunov exponent are used to measure predictability of the northeast monsoon (winter monsoon) by the Educational Global Climate Model (EdGCM) and to test sensitivity of the model to small initial perturbations. The EdGCM sensitive to initial perturbations it is suitable for predictability of the northeast monsoon. The EdGCM is run for 142-year predictions from the year 1958 to 2100. However only the outputs of geopotential height at 500hPa of December from 2012 to 2100 are used for predictability measurement. The results show that the EdGCM predictability for the northeast monsoon forecast is about 120 years. So the EdGCM can be predictability of the long range forecast.
