CO2 emission of rail transportation system plays more important role including the expansion of BTS route that consume the energy and emit CO2 gas more and more. The purpose of this research was to find out amount of CO2 emission from travelling by BTS train and determine specific CO2 emission per product in the form of gCO2e/passenger/km then forecasting on CO2 emission from BTS operations. Research process was initiated from collecting monthly data on ridership distance and electricity for 55 months continuously then regression analysis CUSUM and time series analysis were used for prediction and analysis of CO2 emission. The finding indicated that BTS’s specific CO2 emission was 24.7 gCO2e/passenger/km. Forecasting CO2 Emission from BTS result that Winters Exponential Smoothing Method is most accuracy then Double Exponential Smoothing Method Trend Analysis Method and Decomposition Method respectively. The result of these analysis could be used to calculate carbon footprint from staff travelling by BTS train and promote people to use public transport by government as sustainable transportation concept.

This thesis presents an assessment of voltage sags when faults are happened in the 115 kV transmission line of the Provincial Electricity Authority (PEA) when distributed generation (DG) is installed in the system. The computer program PSCAD/EMTDC (Power Systems Computer Aided Design / Electromagnetic Transient in DC system) version 4.2 is applied to provide electrical parameters for the modeling and simulation and to analyze the fault occurred which resulted in voltage sag. Test results from PSCAD/EMTDC show the values of voltage sag when 5 types of fault are occurred (Single Line to Ground Fault Double Line to Ground Fault Three Phase to Ground Fault Line to Fault and Three Phase Fault). For all cases the value of root mean square voltage before fault is 100% or 1.0 pu. It can be seen that for both radial line and closed circuit when DG are installed in the system the value of phase to ground RMS residual voltage and phase to phase RMS residual voltage at the bus of Bang-pa-in 2 substation are more than the values in case of the system without DG.

The purposes of the study were to investigate transformational leadership and learning organization of bureaucratic official and personnel of Office of the Private Education Commission. The samples were drawn from 169 bureaucratic officials and personnel of Office of the Private Education Commission by Taro Yamane formula sampling. The five-scaled rating questionnaire had obtained the reliability coefficient at 0.95. The collected data were analyzed by the percentage distribution mean and standard deviation; and t-test f-test and Pearson product moment correlation coefficient. The results were as follows. 1. Transformational leadership of the executives from the Office of the Private Education Commission was seen high in general. When considering in each aspect it was found that the samples could highly perceive the executives’ transformational leadership in every aspect ranging from inspiration motivation idealized influence of charisma leadership individualized consideration and intellectual stimulation respectively. 2. Learning Organization of the bureaucratic officials and personnel of Office of the Private Education Commission was high ranging from Mental Model Team Learning Personal Mastery System Thinking and Shared Vision respectively. 3. Transformational leadership and Learning Organization of the bureaucratic officials and personnel of Office of the Private Education Commission were positively related at 0.05 statistical significance and the reliability coefficient at 0.595 which demonstrated the positive relationship averagely.

The purposes of this research were to study sexual risk behavior among adolescent and to explore factors affecting sexual risk behavior among adolescent with early sexual intercourse. Research sample was 396 Mathayom Suksa 1 students (lower-secondary students) in secondary schools under the Jurisdiction of the Office of Basic Education Commission Bangkok which was obtained by multi-stage sampling. Data were collected by questionnaire. Data were analyzed by frequency percentage mean standard deviation independent t-test One Way ANOVA Multiple Comparison and Pearson Product Moment Correlation Coefficientsoftware.The result of the study on sexual risk behavior among adolescent with early sexual intercourse was found at the low level. For the factors affecting sexual risk behavior among adolescent with early sexual intercourse they were found that the personal factor including gender parents marital status family type family accommodation and self-sexual acquisition influenced sexual risk behavior among adolescent with early sexual intercourse at the low level. The attitude factor including they were found that the personal factor including sexual values and attitudes toward opposite sex influenced the sexual risk behavior at the high level. The family factor including family raising family sexual communication and supporting of the association of the opposite sex influenced sexual risk behavior among adolescent with early sexual intercourse at the low level. The social factor including friends were found the low-level sexual risk behavior while low-level sexual knowledge acquisition from schools influenced the high-level of sexual risk behavior and sexual content in the media influenced the moderate-levelsexual risk behavior.For the research hypothesis results of the comparison of the personal factor and the social factor toward sexual risk behavior among adolescent with early sexual intercourse it was found that the there was significantly difference forthe personal factor including gender family accommodation and self-sexual acquisition. However there were not significantly different for the parents’ marital status and family type. There was significantly difference for the family factor including family raising family sexual communication and supporting of the association of the opposite sex.The result of the difference between the personal factor and the social factor toward sexual risk behavior among adolescent with early sexual intercourse was found that there was significantly difference for the personal factor including gender family accommodation and self-sexual acquisition. The result of the difference between the attitude factorand the social factor toward sexual risk behavior among adolescent with early sexual intercourse was found that the attitude factor including sex value and attitude toward opposite sex had negative correlation with sexual risk behavior among adolescent with early sexual intercourse at statistical significance. The social factor including friend and sexual content in the media had positive correlation with sexual risk behavior among adolescent with early sexual intercourse at statistical significance. While sexual knowledge acquisition from school did not have the correlation.

The objective of this study was to examine the wealth management of educational personnel of the office of the Basic Education Commission of Thailand within Dusit District. From the questionnaires the 330 samples can be analyzed using descriptive statistics including percentage frequency and Chi-square and from interviews with the executives of the Basic Education Commission-the Ministry of Education. The results showed that the majority of respondents were female aged between 25-40 years as the civil servants workingperiod of 1-5 years having their revenue of 15001-30000 baht. From the financial planning savings plan were the most. For planning or possession of the most assets included homes land and condominium. The current form of savings is found that commercial banks have the greatest of deposit. Liabilities were mainly from mortgage loans. Source of savings to for retirement is commercial bank deposits. The financial planning was found that most plan for achieving the stability in their lives. The most difficulty in financial planning is not to estimate money in the future. The assumption test at the significance level 0.05 showed that the differences of gender made the differences in the amount of their monthly saving and the return on investment within six months. Status differences are more likely to have the variation of value of house land condominium movable or personal assets financial assets in money market financial assets in the capital markets or assets for investment purposes all liabilities the approximate time to pay current debt the maximum amount of money that is expected to pay up to a month an amount to save each month the desired return on investment within six months and the expectancy of the future investment. The differences of education level are more likely to have the variation of value of house land condominium movable or personal assets all liabilities interest to be paid the maximum amount of money that is expected to pay up to a month the saving rates the saving amount of each month the desired lengths of achieving the goal of an investment. The differences of revenue are more likely to have the variation of value of house land condominium movable of personal assets financial assets in money market financial assets in the capital markets or assets for investment purposes total value of all liabilities to be paid interest to be paid estimated time to pay current debt the money that is expected to pay up to a month the monthly desired saving rates time to achieve the goal of saving the saving amount of each month investment decisions the demand in return on investment within 6 months and the tax deduction items
