This thesis is duplicated of the controlled of the AC. Three Phase Generator with case study and analyze of the characteristic of generator in various operating conditions. By the model works of the actual use in establishment generator this is using generator for backup electricity from main feeder. We have the functional testing of start or stop for check store the characteristics in different conditions at that time. Load distributing of generator for check store parameters. The parallelization of generator into the system in case of emergency while the failure of the mains system. The degradation of generator off the system when main is back to normal or the emergency stops of generator in case of accident during the operation.

Brake system is used the friction between disk and pads. In the driving conditions the brake behavior from the driver is difference. Based on this reason the damage on disk and pads are occurring. Nowadays the ratio of compound materials in pads is several and involved automotive industry has not available enough to experiment. Thus it is difficult to brake pads damaged analyzing in several driving conditions. In this problem the mechanical property tester is main tool for experimenting. And test procedure based on the Brake lining and disc brake pads compressibility JIS D 4413 [7]. The experiment emphasizes on the flexibility behavior and internal energy by volume with 3 types of brake lining and pads. For the experiment focused on conditions by normal apply brake repeat apply brake and suddenly apply brake. The results revealed the normal apply brake condition the maximum and minimum of flexibility behavior was appeared on brake lining and pads type A and type C with testing temperature at 2000C. By the repeat and suddenly apply brake conditions the brake lining and pads type C and type A with 300C is given to the maximum and minimum flexibility behavior. In case of internal energy by volume the maximum and minimum energy was appeared on pads type C and B at the 300C of testing temperature. For the testing temperature at 200 and 4000C the pads type A and type B were got the maximum and minimum energy respectively. On the other hand at the high flexibility behavior is given to high internal energy at the high temperature of the apply brake condition.

This study was aimed to study the demographic characteristics of who decided to shop online to explore working-age people’s internet behavior and to investigate the demographic factors influencing internet shopping decisions. The population and sample used in this study were working-age people drawn from Snowball Sampling method. The questionnaire used was distributed through the internet to 400 respondents. The data were collected and analyzed by the computer program through the statistical analysis including frequency percentage mean () standard deviation (S.D.) and two-way analysis (ANOVA). The research results revealed that Marketing mix factors affected the internet shopping decisions of the working-age people in general at high level (= 4.13 S. D. = 0.430) . When looking into each aspect it was found that the price factor highly influenced the online purchasing decisions (= 4.16 S. D. = 0.463) . followed by the product factor (= 4.13 S. D. = 0.452) which was also considered at high level. The promotion factor had high impact on online shopping decision (= 4.13 S. D. = 0.422) as well as the distribution channel (= 4.13 S. D. = 0.386). The result regarding the relationship revealing gender and age (F = gender *age (1357) = 7.128 p < .05 ) had a significant effect on online shopping at the .05 level. Gender * and occupation (4357 ) = 1.503 p < .05 ) had influence on decisions to online shopping with statistical significance at .05. Occupations and income (F * occupation * income (1357) = 11.487 p < 0.5 ) could influence decision making on the internet shopping with statistical significance at .05. Also the relationship between gender and occupation (F * gender occupation ( 4357 ) = 5.237 p < .05 ) had an influence on the choice of the internet shopping decision on price at the .05 level; the relationship of gender and occupation (F * sex occupation ( 1357 ) =8.000 p < .05 ) influenced the decision to shop on the internet in terms of marketing promotion at the .05 level of significance.

This study aims to examine directions for addressing student quarrel problems in a private vocational college and to propose the possible directions in preventing and solving those problems. It is a qualitative research using the in-depth interview technique. There are a total number of 21 key informants: 1 education institute administrator 5 teachers having either direct experiences on quarrels or students under their supervision involving in quarrels 10 students (5 alumni and 5 current students) who have engaged in quarrels and 5 guardians of students involving in the quarrels. According to the research results there are 4 principal causes of quarrels: 1) friends and senior students; 2) internal environment of family; 3) students’ lifestyle culture; and 4) college location. Today thanks to the technological advancement the revilement or provocation of quarrels or insult is not limited to the face-to-face style alone; it can also be made through online social media (Facebook or LINE application). This eventually leads to the serious quarrels. The quarrel nowadays is not for personal satisfaction or revenge to frighten other party but for killing. In this regard the measures according to the Ministry of Education’s quarrel prevention and solution strategy are: recordkeeping firearm inspection and appointment of teachers to be stationed at certain risk locations. These actions succeed in reducing the number and severity of quarrels. Moreover it is also found that the measures proclaimed by virtue of Section 44 of Constitution of the Kingdom of Thailand (Interim) B.E. 2557 (2014) are also highly effective in solving quarrel problems. Nonetheless the discussions between the education institute administrators are the unsuccessful solution for solving the quarrel problems among vocational students.
