This research proposes a Bayesian logistic regression model which is applied to the data from autoparts manufacturing machines. Factors related to defective and bad products are investigated. The proposed model is compared with the logistic regression using maximum likelihood method for parameter estimation. The data were collected from 132 machines in an autoparts manufacturing factory. The research found that useful life machine type 6 worker group 3 and 4 working step 1 and 2 influence to the risk of producing defective and bad products. When the useful life is increased by 1 month the risk of producing defective and bad products will be increased by 2.2%. The risk that the machine type 6 will produce defective and bad products is 4.078 times greater than the risk that the machine type will do. The risk that the worker group 3 will produce defective and bad products is 61.7% less than the risk that the worker group 12 will do. The risk that the worker group 4 will produce defective and bad products is 61.5% less than the risk that the worker group 12 will do. The risk that the working step 1 will produce defective and bad products is 2.831 times greater than the risk that the working step 4 will do. The risk that the working step 2 will produce defective and bad products is 13.8 % greater than the risk that the working step 4 will do. The parameter estimates from the Bayesian logistic regression are very close to the ones from the logistic regression using maximum likelihood method for parameter estimation

The objectives of the research were (1) to study perception of Integrated Marketing Communication (IMC) of Air Force Clubs (2) to study aspect of fans to Air Force Club’s image (3) to compare demographic characteristics with Air Force Club’s image and to study correlation of IMC of Air Force Club’s image with Air Force Club’s image. The data were collected by using questionnaire sampling from 400 members who were fans of Air Force Club. Data analysis employed frequency percentage arithmetic mean (􀝔􀒧) and standard deviation (S.D.) statistics used for hypothesis testing include t-test one-way analysis of variance and Pearson Product Moment Correlation Coefficient. The study presented the following results:Demographic Fans’Air Force Club were males (78.50%) ages between 25-34 (42.00%) government/stage enterprises occupation (42.75%) average monthly income between 20001-30000 baht (33.00%) marital status (48.30%) and lower than bachelor degree (82.50%) Demographic Air Force Club Fans from the middle class get news updates about the league from IMC social media television broadcast and radio reports. The fans are generally concerned about the league’s game results club’s news and information league’s schedule and result of drawing lots. Demographic Air Force Club Fans play a big role in bringing the image of Air Force Club in high level. The hypothesis testing showed that different occupation average monthly income and marital status of fans’ Air Force Clubhad statistically significant differences at the level of .05 on Air Force Club’s image. On the contrary difference in gender age education had no statistical significance for their Air Force Club’s image. The IMC of Air Force Club showed correlation with Air Force Club’s imageatstatistical significance .05that was three channelsincluding television broadcastingmedia radio broadcasting media and printed media.

This paper presents a study of comparison of PWM power rectifier between 6 Pules and 12 Pules converter topology by small hydro turbine Generator (20kW) is power supply and Compare harmonics Current feed in the systems. Both converter connected Permanent Magnet Synchronous Generator (PMSG) and Voltage Regulator Control at 700 V. The control system by Decoupling Control and Conventional PI Control for control parameter PI value by Nicole-Ziegler method. Analysis for Performance of the system presented a mathematical model with Matlab/Simulink program. The result of simulation have value less than 5 percent of ripple voltage and Voltage Control continuously. Converter 12 pulse have harmonics Current value feed in the systems less than converter 6 pulse. This Case study can apply using PWM power rectifier control in future work

Currently the internet services with 3G technology by mobile phone operators in Thailand are different in the performance. The mobile phone operators have already launched 3G technology with 2G frequency ranges which are limited in the efficiency. This paper aims to compare the efficiency of the internet service with 3G technology by three mobile phone operators (AIS DTAC and Truemove H) in Thailand. There are three type of testing as follows: Ping to both domestic and international website Bandwidth speed test and FTP Test (upload and download) are used to evaluate the performance of these mobile phone operators. There were five places in Bangkok where are the top of the network congestion list for such testing the three mobile phone operators. The result showed that AIS gives the best performance in the ping test. Truemove H introduces the best performance in both FTP and Bandwidth speed test. The DTAC performances are moderated level for every tests.

This research was to study the feasibility of CIGS for condominiums in Thailand by studying the energy consumption of building which divide by behavior of users which interested in day time users and night time users. Then study approach and feasibility to apply CIGS for condominiums by consider energy consumption and economic efficiency of installation CIGS for energy conservation. The result showed that when installed 110 watts/m2 of CIGSs on windows in a room type can be provide electricity 2.51 kWh per day 2.81 kWh per day and 3.75 kWh per day which can be represented 40 percent of the total energy consumption. In other word can be reduce energy supply from grid per month 75.30 kWh 84.3 kWh and 112.50 kWh. While investment cost per square meter of CIGS is about 23000 - 35000 baht which equivalent to 3 percent of total condominium price that mean payback period is about 8 years. Although CIGS is not able to provide all of electric consumption in building but from the assessment of economics found that there is a very interesting to investment it should be interested policy for the government to enforce condominium to install CIGS for sustainable development.
