This paper presented the effectiveness of clustering data – the results from when the Fuzzy Kernel Compactness and Separation (FKCS) were proposed to compare with the performance of the Kernel Noise Clustering (KNC). The FKCS and KNC had largely been developed through basic steps of the Fuzzy Compactness and Separation (FCS) and Noise Clustering (NC) respectively. Ring data sets were used to test the effectiveness of clustering data between the FKCS and the KNC. In doing so the kernel function – the kernel gaussian function and the kernel polynomial function were used as testors. Along those processes noise data was added in order to test noise-resistant capacity of Fuzzy Kernel C-Mean (FKCM) FKCS and KNC. The results of the tests provided quite knowledgable understanding that when trying out with the ring datasets the FKCS with kernel gaussian function and kernel polynomial function could perform effectively clustering data. Moreover the KNC was even more robust and could work out better with noise data than the FKCM or the FKCS could.

This study was aimed to investigate how the role-play can be increased students’ selfconfidence in using English for Communication Arts-Comm. Arts as well as the students’ attitudes towards the use of role-play in English for Communication Arts class. There are 64 students who registered in second semester 2008 at Rambhai Barni Rajabhat University--RBRU. Since students’ confidence was difficult to determine and measure objectively the technique required information from the students through pre and post questionnaires. The data were two periods collected before and after Role-play using in English for Communication Arts class. And the data were thereby formulated and tabulated in terms of frequency percentage mean and standard deviation. The hypothesis was tested by a pair sample test. The findings of the study indicated that role-plays could increase the majority of the students’ confidence to use English for Communication in Comm. Arts. field and also showed that most students had positive attitudes and interesting activity toward the use of role-play in Comm. Arts course.

The purposes of this research were 1) to study the participation of parents in educational management in children educational development centers Prapadang District Samutprakarn Province 2) to compare the parents’ participation level. 3) to study the problems and suggestions of parents. The data were collected from 335 parents. The instrument used to collect data was a questionnaire. Data were processed by percentage mean standard deviation t-test and one-way analysis of variance (ANOVA). The results of research were found that 1) participation of parents were at the least level. 2) to compare the parents’ participation it was found that gender was not different while the participation of parents with different vocation and education level found the difference 3) the problems were the parents had to work and were busy. The suggestions were PTA and should find finding volunteers for the centers.

The purposes of the research were to create and find efficiency validation of computer assisted instruction focused on the practice to record data for report writing for t Ie standard 90/90 and analyze the student learning achievement after using (computer assisted instruction. The I samples were the 20 first year Bachelor of Science in Technical Education st~dents enrolled in Industrial Engineering Rajamangala University of Technology fhra Nakhon North Bangkok Campus. The Researcher experimented by using prete~t and then using the computer assisted instruction focus on the practice to Iprepare specimens in learning next the students did the posttest. After that the resrarcher calculated to find the computer assisted instruction efficiency and analyzed:! the students leaning achievement after studying. The result revealed that the computer assisted Instruction efficiency was efficient for standard 90 / 90. And after studying by using computer assisted instruction tme students learning achievement increased significantly at 0.05.

Corporate governance principle has played an important role in predicting the business failure because the concept of good corporate governance will result in value and value added to the business and shareholders. Several previous studies attempt to find the relationship between corporate governance mechanisms and firm’s performance. It was expected that company with good performance will not be likely to go bankrupt. However this article reviews the compiled documents and studies in the past concerning corporate governance mechanisms (board structure board committees and ownership) as application tool to predict business failures.
