The purposes of this research were to analyze arts and sciences educational management circumstance in general education course of higher education. Including study arts and sciences educational management in general education course in the 21st century. They were mixed method research. The data were analyzed by descriptive statistics and content analysis. It was found that the current circumstance of arts and sciences educational management in general education course of higher education found 3 parts; (1) the teaching process in general education courses focused on relationship skills knowledge cognitive skills and the numerical analysis teaching (2) responsive subjects in teaching methods the instructor focused on instruction emphasizing on the combination approach teaching used practice and research teaching (3) teaching activities the instructor emphasized in classroom activities rather than outside classroom activities. The approach of arts and science educational management in general education courses corresponds to learning in the 21st century found that focus on living and working with teaching process in the moral and ethics the knowledge cognitive skills relationship skills and the numerical analysis. The cognitive skills and innovation should focus on the teaching of moral and ethics and the knowledge and IT skills media and technology should focus on moral and ethics teaching the knowledge and cognitive skills.

The purposes of this research were to analyze the welfare conditions and needs including study the welfare suitable styles for the service sector workers of taxi drivers. The research was future research. The data were analyzed by descriptive statistics and inter quartile range. The results revealed that: The taxi drivers were mainly males more than females; aged between 45-54 years married secondary education provinces hometown the period of time in the taxi drivers’ career were between 3-7 years the average income was about 9000-12000 baht per month. The mostly problems of quality life were such as low income and inaccurate high cost of career had not got sufficient welfare unsafely in career lack of skills development and knowledge. The welfare conditions and needs were found that the average was high level in 4.22.

The objective of this research aimed to study factors affecting earning persistence and firm value of list firms in the stock exchange of Thailand in set 100 Index. The data was collected in 5 years period from 2011 – 2015 which including 213 samples and then analyzed data by using descriptive statistics and multiple regression analysis. The research revealed growth rate of sales current earnings and cash flow for short term investment reflected to earnings persistence. Furthermore this research also shed some light on factors affecting firm value and found that earnings persistence financial risk dispersed ownership structure and discretionary accrual directly affected to firm value. These results provided more information to investors about significant factors for decision making especially discretionary accrual factor. Therefore firms who have low level of earnings management and high level of earning persistence will reflect to future firm value.

Increasing concentrations of CO2 in the atmosphere is causing severe environmental destruction to the earth. Bio-sequestration of CO2 is a promising way to completely sequester CO2 by converting it into biomass by way of photosynthesis. The current research focused on biomass productivity and CO2 sequestration efficiency using microalgae. The experiment choose Spirulina sp. RMUTL by cultivating in working volume 8 liters bioreactor with zarrouks medium for 24-hrs with light nature and aeration air. The CO2 (100%) was flushed into the medium with a flow rate were 0.01 0.02 and 0.03 vvm respectively. The period of all experiments were 30 days. The results showed that the maximum specific growth rate OD560 algae biomass productivity efficiency of CO2 reduction CO2 fixation rate and carbon loading rate were 0.35±0.01 d-1 0.85±0.00 600.00±10.00 mg.L-1 96.83±0.76% 1 128.00±18.80 mg.L-1.d-1 and 2 0 . 4 1 ±0 . 2 6 g. d-1 with 0.01 vvm CO2 flow rate. The average CO2 sequestration over 30 days were 3.15.±0.03 3.11.±0.02 and 3.07.±0.07% in 0.01 0.02 and 0.03 vvm CO2 flow rate respectively.
