This research is the comparative study of three forecasting methods on SET 100 index. These methods are Simple Exponential Smoothing method Holts method and Box-Jenkins method. Two sets of data were used in this study. The first one used as a training set was collected from January 2 2008 to September 30 2011. The other one used as a testing set was collected from October 3 2011 to October 14 2011. We propose that the most appropriate forecasting method is the one which give the lowest MAE MSE MAPE and diagnostic checking. The results show that Holt’s method displays the lowest MAE MSE and MAPE. The next one is Box-Jenkins method while the Simple Exponential Smoothing method exhibits the highest value of all three indicators. However the model from Box-Jenkins method is the only one way that reveals no residual autocorrelation. This leads to the conclusion that the appropriate models for forecasting of SET 100 Index is ARIMA (213).

The purposes of this research are 1) to create computer multimedia through the Internet teaching tool for lighting for broadcasting course (undergraduate level) 2) to develop and to find out quality the create computer multimedia through the Internet teaching tool for lighting for broadcasting course (undergraduate level) and to achieve efficiency according to a set of 90/90 criterion. The samples for this study were 48 second year students of Bachelor of Technology Program in Radio and Television Broadcasting Technology studying this course in the first semester of 2011 academic year at Rajamangala University of Technology Phra Nakhon. The samples were selected by simple random sampling. The research tools used are the computer multimedia through the Internet an achievement test evaluation forms for quality assessment. Statistics used for analyzing the data were percentage and mean. The results of the study revealed that the computer multimedia instruction through the Internet was ranked as a very good level by content experts and as a very good level by educational technology experts and had its efficiency of 94.80/96.60 it was higher than criteria set 90/90

This research aims to study influence of factors on crisis communication in tourism and integrated marketing communication of entrepreneurs and foreign tourists. This study is quantitative research by survey using end-closed questionnaires with data collecting from 400 foreign tourists and 400 entrepreneurs. The statistics used for data analysis by descriptive analysis include Frequency Distributions Percentage Mean Standard deviation. And analyze The Linear structural equations modeling by LISREL. The research results showed that the foreign tourists expected that during the crisis Thailand should ensure the safety of tourists. The most suitable integrated marketing communication tool after crisis is country identities. From entrepreneurs’ side they also expected that the entrepreneur should be communicated directly with officer in charge during the crisis about sale promotion and changed tourism program for safety. Also the most suitable integrated marketing communication tool after the crisis is internet. The linear structural equation modeling of either group is consistent with the empirical data. Thailand reacted to the crisis occurred rapidly by using the two-way communication to provide information to tourists best describe crisis communication at 87 percent. On the other hand marketing promotion best describe integrated marketing communication at 74 percent.

The purpose of this research is to study Quality of work life affecting Organizational Commitment of private companies’ employees in Lopburi Province. Sample size in this research is 400 samples. Questionnaire is a tool for data collection. Statistics for data analysis are percentage mean standard deviation t-test one-way analysis of variance and multiple regressions analysis. Research results are as follows: Organizational commitment in the dimension of Strong belief in and acceptance of the organization’s goals has the relationship with Development of Human Capacities and Social Relevance. Organizational commitment in the dimension of Willingness to exert considerable effort on behalf of the organization has the relationship with Adequate and Fair Compensation Development of Human Capacities and Work Life Balance. Organizational commitment in the dimension of Strong desire to maintain membership in the organization has the relationship with Adequate and Fair Compensation Growth and Security and Social integration.

The optimum conditions of extracting pectin from vegetables and fruits are apples grapefruit lemons and bananas were studied. It was found that pectin from grapefruit peel gave good physical property white and has a relatively highest yield. Therefore in this study was interested to choose grapefruit peel as raw materials to optimum the conditions of pectin extraction. In the process of pectin extraction the temperatures of the extraction were studied at various 50 60 70 80 and 90 ?C by using hydrochloric acid for 24 hours. It was found that when the temperature increased the pectin extract was increased while at 80 and 90 ?C have a similar effect. After that pH conditions of the extraction were studied by various acids such as hydrochloric acid nitric acid and acetic acid at the same concentration of 1.0 molar at 80 C for 24 hours (1440 minutes). The results found that hydrochloric acid gave maximum pectin extracted yield. Finally the extraction times were studied at 30 60 90 120 and 1440 minutes using 1.0 M hydrochloric acid. From this work can optimized the pectin extraction condition as of 80 C and the extraction time was 90 minutes that gave maximum yield of pectin. At the otherwise the times of extraction have no effect to the amount of pectin. The potential from this study had satisfactory results can be used to improve the extraction of pectin system.
