This paper presents a study of low-frequency oscillations in compensated electric power systems with Flexible AC Transmission System of the power system frequency using PSAT Tool box To assist in the analysis of the stability of the system When the power transients in power systems is simulated By using standard IEEE 14 bus system as a case study. The Equipment that used to control the swing frequency of the is a flexible electrical power control devices or FACTS are two kinds of serial and parallel. The analysis showed that two models are compared with the time (Time Domain) and see the effect of the Eigen (Eigen Value) of the simulation results show work to see that controls are electrical flexible compensation. of low frequency oscillations in power systems in acceptable coordinates

The purposes of this research were to study the characteristics attitudes behavior and the needs of foreign tourists towards the hospitality of Chiang Rai people. The result found that most of foreign tourists were male ages 45 married and with Bachelor’s Degree. Their yearly income was upper 45001 US dollars. The objective of traveling was for pleasure. They got tourist information from others media : friends information display boards and tourist agencies. The overall attitudes of foriengner towards the hospitality of Chaing Rai people are at high level : Frendship accommodations migration convenience foods and restaurants safety tour and guide services transportation convenience public utilities and information services respectively. Most of them came to this province for the first time with their families and friends. They were most interested in natural sightseeing. They liked to stay in hotels and guess houses. They tend to come back and will recommend to others about Chiang Rai. They need a good hospitality signs for giving direction in English Officials safety staying in city with good location tourist information displays tourist assistance center officials for taking care of tourists with good skills of foreign languages providers polite speaking and guides are not exploited being honest.

A case study of community’s Ban Mai Fad Tambon Maifad Sikoa district Trang province. A sample was selected from 1193 cases were included as a sample. The purposes of this study were: 1) the structure of the family how to choose a pair of family members relationships occupation of the person in the family education and ethics in the community 2) the effects of cultural change in the community after the founding of Rajamangala University of Technology Srivijaya Trang campus. Analysis to determine the percentage by using Microsoft excels. The results of the study were as follows: 1) Family structure 31.52 percent is single family and 31.52 percent is the extended family. 2) Families are encouraged to choose their own spouses to marry a stranger much more. 3) Family relationships of persons in interdependent and live together as a kinship. 4) Families to teach children to recognize the importance of education. 5) Encourage the child to learn at a higher level. Teach children not to drink alcohol smoke. Encouraged to practice religious activities and encourage participation with the public events. 6) Family changed from large to small and medium local languages in communication. 7) Community changed after the founding of University was as follows: Increasing income there are various types of business increase social change from a rural society to an urban society more problems of teenagers and environmental issues such as waste problems.

The purposes of this study were 1) to create a construction of design program for practical skills system of engine repairing 2) to determine the quality of design program for practical skills system of engine repairing 3) to evaluate the users’ satisfaction of a design program for practical skills system of engine repairing. The sample used in this study consisted of 30 lecturers from automotive division university and 39 lecturers from the office of vocational education commission. The tools used in this study were the quality assessment for practical skills system of engine repairing and the satisfaction assessment of the users to design program for practical skills system of engine repairing. The statistics used for data analysis were percentage mean standard deviation and t-test for dependent samples. The results of the study were as follows: 1) the quality of were very good level design program of for practical skills system of engine repairing( = 4.70 S.D. = 0.21). 2) User’s satisfaction level after accessing the program were very good level ( = 4.60 S.D. = 0.11). 3) The results were compared to assess the satisfaction level of the user from Nakhonphanom university and the office of vocational education commission towards of design program for practical skills system of engine repairing in the field of design content and application found that in each of the satisfaction level did not differ significantly at .05 level. 4) The results were compared to assess the satisfaction level of industrial community education and technical college towards of design program for practical skills system of engine repairing in the field of design content and the application found that in each of the satisfaction level did not difference at significance level .05

Nowadays electrical current measurements can be categorized into two methods; direct and indirect measurements. The small amount of electrical current can be directly measured by means of electrical current instrument whereas the current of high voltage cannot directly be measured by means of any physical contact of an instrument on the other hand it can be indirectly be measured through voltage transformer by stepping down voltage method in which cannot be realized economically and practically. This paper presents a method of measuring high voltage current by means of Rogowski coil detecting induced electromagnetic ware compensating unwanted induced current and finally amplifying. The results are that the reduction of measurement time and cost of purchasing the instrument.
