The research aimed to study and develop handicraft products from elephant dung paper for community income generation in Ayutthaya province and to compare the product satisfaction of the target group for the original style and the new one of elephant dung paper The target group eas from 143 tourists from other provinces and 143 of local tourists. Both of target groups would like to but handicraft products from elephant dung paper and helped generate community income in Ayutthaya province. Research tool eas done by questionnaire and data were analyzed by statistically percentage mean and mode. Questionnaire was used for the product attributes satisfacion avaluation of the target grouq including alternative evaluation process and comparison of product styles evaluation process. Data were analyzed by statistically percentage.mean and t-test dependent sample The results of were foun as follows: 1. The target group chose the third style of handicraft products from elephant dung paper 2. For the product attributs satisfaction of the target group it was found that the new style of hansicraft prosuct was more acceptable than the oniginal one at a significance level of 0.05.

This article presents The Analysis for high-Voltage Electric Stress in Lp and Ls coils of Tesla Transformer for studying the efficiency design. The tesla transformer is designed at 350kV rating Voltage and 120 kHz resonant frequency. The effect of high voltage when we designed the coil has impact to Electric Stress between primary and secondary coil because the tesla transformer uses air core. The insulator of coil also has problem on the reason as flashover on the 2 coils. The best dimension among coil has to present in this paper by using optimal mathematical solution. The simulation results show performance of the solution and ensure the methodology with positive way.

The purposes of this research were : 1) study the personal factors of undergraduate 1 st year students Dusit Thani College 2) the decision to undergraduate of 1st year students Dusit Thani College and 3) personal factors that affect the decision of undergraduate 1 st year students Dusit Thani College. The samples students were studying in undergraduate 1st year Dusit Thani College 229. The instrument used in this research was the statistical methods used to analyzed data were frequency percentage mean standard deviation t-test and one-way analysis of variance. Data were analyze using a computer program. The results showed that: 1) Individual students 1st year Dusit Thani College most were female parents of students a professional commercial / personal career. The parents of students a bachelors degree. The parents of students were earning more than 30001 baht and students were living in dorm / house / condominium 2) the study of undergraduates Dusit Thani College students were as a priority.
