This research study was aimed to investigate 1) elementary Information economic and social factors 2) happiness 3) compare the level of happiness classified by elementary information and economic factors and 4) study the relationship between social factors with the happiness of the people. The sample consisted of 400 people living in the community of National Housing (Wat PhraNgoen). The statistics used were frequency percentage mean standard deviation the comparison of t-Test and f-Test with one-way ANOVA and Pearsons Product-moment correlation coefficient. It was found that most of the samples were married females between the ages of 41-50 years old with high school education (M.4 - M.6) or vocational training. They had their own business and the number of family members were one or two persons earning the personal income per month of 10001 - 15000 per person and the family income per month of 10001 - 20000 Baht without the implementation of the household accounting. Their household expenses included the payment for water electricity and other utilities. Most of them had liabilities and had to make the payment of 29.44% for debt repayment on time. The debt settlement was moderate with a few savings each month and the income was closely equal to the expenditure. In the overall the people had practical social factors. In the overall each aspect also yielded high level of family leisure and personal relationship while the remaining three including the social relationship living behavior and the community characteristics were moderate. In addition the results revealed that senior people number of family members and the difference in debt payment had different levels of happiness in the overall. The social factors had a low positive relationship with the happiness of the residents living in the community of National Housing (Wat PhraNgoen) at the .05 statistic level.

The research on development of pattern of cotton by using weaving technique in type of Mudmee fabric for metrosexual menswear by method of cutting and connecting has the objectives to : 1) develop pattern of cotton by using weaving technique in type of Mudmee fabric; 2) design of metrosexual menswear by using cutting and connecting from developed Mudmee cotton; 3) design the brand and packaging product to increase product value; 4) survey satisfaction of target group. The researcher studied by using Art Nouveau concept and by designing the cotton pattern by using Mudmee weaving technique numbering three patterns binding to make pattern woven to be fabric in order to make menswear in metrosexual style by using the method of cutting and connecting prototype consisting of one set of vest two sets of suits and two sets of overcoats as well as designing of brand numbering five types at the same time The researcher designed packaging product in five types using in surveying satisfaction of target group of thirty persons: Designer Merchandiser Graphic designer Visual merchandiser and person having fabric weaving experience by method of purposive sampling analyzing data by using statistics percentage mean and standard deviation. The study result was found that most respondents were female aged 36-40 years single status most have taste of female gender having income of 45001 Baht onwards. The educational level was Bachelor Degree. Respondents previously bought and used products and accessories for clothes from Mudmee cotton. The types selected to buy the most were vests bags and shawls respectively. The occasions in wearing the most of all were important festivals selecting to buy clothes and accessories for clothes from cotton by using Mudmee weaving technique in each occasion price 500-1000 Baht per one piece. Most persons participating in deciding to buy were friends. The sets of clothes for the groups wishing to design in sets of woman clothes. The result of satisfaction analysis of target group towards development of cotton pattern by using Mudmee weaving technique for metrosexual menswear by using cutting and connecting method it was found that target group had satisfaction in much level ( x= 4.16). The result of satisfaction analysis of target group towards design of metrosexual menswear by using cutting and connecting method it was found that target group had satisfaction towards the clothes in every type in much level (x= 4.26). The type which had mean of the highest satisfaction in the three first types including suit in type No.3 (x = 4.31); the second was vest type No.1 (x= 4.29) and overcoat type No.4 (x= 4.27). The result of satisfaction analysis towards format of brand and packaging product it was found that target group had satisfaction in much level having x= 4.23 and 4.30 respectively.

Nowadays brake pad is a one of products that plays a role in the automotive parts industry and directly affects safety. Therefore there are many designs of brake pad for product development. The technique of reinforcing the layer in brake pads is another option for developing such products. The objectives of this research are to solve the problem of noise from brake pads using the material layer reinforcement technique and raise the quality of brake pads to use in the industrial sector. As a result the prototype brake pads with reinforcement techniques by means of damping layer were performed. Consequently the experimental work reveals that the brake pads with damping layer technique for brake pads can reduce vibration and also brake noise at the same frequency at less 10 percent at braking speeds of 50 100 and 130 km/h. Besides this technique can be applied to the production of brake pads in the same formula. However the prototype brake pads is still in the product development phase for testing in a variety of conditions both temperature factors and usage period

The aim of this work was to validate the sample preparation using a microwave digestion for determination of total arsenic in a spiked soil. Graphite fernace atomic absorbtion spectrophotometer (GFAAS) technique was used to determine the total arsenic using palladium nitrate Pd(NO3)3 as a modifier agent. The instrumental detection was performed under the condition steps of drying ashing atomizing and cleaning to be 100 1200 2250 and 2600 C. The external calibration curve was constructed using the automatic program based on the master standard of arsenic with 20 ppb. It was found that linearity range was in the range of 1 to 20 ppb with R2>0.999. Based on microwave digestion condition the sample preparation with and without HF was also compared the total arsenic in the spiked soil with a 10 ppb. The result shoewd that the arsenic content obtained fron the prearation with and without HF did not significantly diferent at the 95% confidence limit. The recovery was 80.3 and 82.3% for the spiked sample with 2.5 and 10 ppb respectively. The relative standard deviation was 2.15% (n=11). The results of this work can also confirmed that the preparation method using microwave digestion provided the more advantages such as rapid a little volume of reagents completely digestion.

The objectives of this research are to propose a model for estimating and detecting rice yields in Thailand to investigate the factors related to the rice yields to find the trend and to construct the maps of rice yields in Thailand. A linear mixed model (LMM) including the spatial effects which follow the conditional autoregressive model (CAR) and the time effects which follow the first-order linear autoregressive (AR(1)) model is proposed. The estimated rice yields are used to construct the rice yield maps in Thailand. The dependent variables are the rice yield in each month of each province. The factors considered are rainfall average temperatures and regions. The results indicate that the factors enfluencing the rice yields are rainfall average temperatures and regions (North Northeast South East West Central region is a refrence region). The trend also effects the rice yields. The rice yeilds maps are easy for readers to identify which areas have high or low yields and easy to compare the yields among areas by looking at their different colors.
