This research presents a study of the compressive strength chloride penetration and resistance to corrosion of concrete containing bottom ash. Fine and coarse aggregate is partially replaced with bottom ash 25 50 75 and 100% by weight of the aggregate. The results show that the compressive strength and low chloride penetration of concrete improves substantially with partial replacement of aggregate with bottom ash. Concrete mix cement containing 25 and 50% of bottom ash can be used to make coarse aggregate. In addition Concrete mix cement containing 100% of bottom ash can be used to make fine aggregate. The use of bottom ash produces concrete mix with good compressive strength and resistance to chloride and corrosion.

This research presents a study of the compressive strength tensile strength flexural strength and water absorption of Cellular Lightweight Concrete containing fine fly ash and ground bagasse ash. Portland cement (CT) is partially replaced with pozzolans 20 30 and 40% by weight of the cementitious materials. The results show that the compressive strength tensile strength flexural strength and low water absorption of Cellular Lightweight Concrete improves substantially with partial replacement of Portland cement with fly ash and bagasse ash. Cellular Lightweight Concrete mix cement containing 20 and 30% of pozzolans can be used to make cementitious materials. In addition the use of fly ash and ground bagasse ash produces Cellular Lightweight Concrete mix with good compressive strength tensile strength flexural strength and water absorption.

The purposes of this research are to examine the students’ Awareness and Behavior on Mobile Phone Hazardous Waste Management (ABMPWM) comparative studies of dependent variables among the levels of independent variables and their Corresponding correlation’s between their exposure to information and ABMPWM and to yield the appropriate means for managing mobile phone waste. The survey research using self-administered questionnaires was conducted on 450 random samples from 264027 students with study standing at junior and senior high school in Bangkok. The analytical statistical methods used were percentage mode mean S.D.(Standard Deviation) T-Test F-Test One-way ANOVA Analysis Correlation Analysis and Regression Analysis & Prediction Model. The level of the Awareness on Mobile Phone Hazardous Waste Management index (AMPHWM index) was high. The AMPHWM index of men was higher than women and significance difference (p<.05). The group of 13-14 years of age had AMPHWM index at the highest level. The samples of junior high school students had higher AMPHWM index than the group of senior high school students. The group of students who bought the mobile phone themselves had higher AMPHWM index than the others. The group of students belonging the mobile phone with 15000 baht had higher AMPHWM index than the low price. The group of students paying service charge monthly about 301-500 had higher AMPHWM index than the group paying more or less. The group of exposure to information had higher AMPHWM than no exposure to information group. Most of students received information from T.V.. The Awareness on Management of Mobile Phone Waste of the group of exposure to information and the group did not expose to information had correlation to the Behavior on Management of Mobile Phone Waste. The level of the Behavior on Mobile Phone Hazardous Waste Management index (BMPHWM index ) was average. The BMPHWM index of men was higher than women. The group of 13-14 years of age had higher than the others. The samples of junior high school students had higher BMPHWM index than the group of senior high school students. The group of students who bought the mobile phone themselves had higher BMPHWM index than the others. The group of students belonging the mobile phone with more 8001-15000 baht had higher BMPHWM index than the lower and higher price. The group of students paying service charge monthly about 301-500 had higher BMPHWM than the group paying more or less. The group of exposure to information had higher BMPHWM index than no exposure to information group. The group of students received information from internet or electric media had higher BMPHWM index than the group students who received the information from the others.

The objectives of this research were: 1) to study psycho-social factors related to effective teaching behavior of the lectures at Faculty of Business Administration Rajamangala university of Technology Bangkok metropolitan 2) to study social characteristics and psychological characteristics that could predict effective teaching behavior of the lectures in overall and small groups at Faculty of Business Administration Rajamangala university of Technology Bangkok metropolitan 3) to study the interaction between social characteristics and psychological characteristics affecting to effective teaching behavior of the lectures at Faculty of Business Administration Rajamangala university of Technology Bangkok metropolitan. The sample used in this study consisted of 252 lectures at Faculty of Business Administration Rajamangala university of Technology Bangkok metropolitan. There were three independent variables. One was social support and the other two were innovation acceptance and attitude towards effective teaching behavior. The dependent variable was effective teaching behavior. Statistical analysis stepwise multiple regressions Two –Way ANOVA were applied to analyze lecturers in both overall and small groups according to their biosocial factors. The results of the study are as follows. 1. Three major variables to predict the lecturers’ effective teaching behavior are variables from social characteristics and psychological characteristics. In the overall group the percentage of the predictability score is 54.40. In smaller groups the percentage of the predictability score ranges from 44.60 to 62.90. The highest score is predicted by attitude towards effective teaching innovation acceptance and social support in Rajamangala university of Technology Ratanakosin. 2. The analysis from Two –Way ANOVA shows that the lecturers who highly accepted innovation and received high social support showed highly effective teaching. However the factors of innovation acceptance as well as social support had no interaction with the lecturers’ effective teaching behavior. When looking into each independent variable it was found that the score of effective teaching behavior varied according to the innovation acceptance in overall group and smaller groups which were classified into groups of male lecturers female lecturers inexperienced lecturers experienced lecturers higher-than-bachelors degree lecturers single lecturers married lecturers and lecturers from four centers of Rajamangala university of Technology. It was also found that the score of social support varied in both overall group and smaller groups of male lecturers female lecturers younger lecturers senior lecturers experienced lecturers higher-than-bachelors degree lecturers and married lecturers. In case of lectures having attitude of effective teaching behavior and being socially supported when looking into each of the independent variables and there was no interaction between them. The score of effective teaching behavior varied in accordance with attitude of effective teaching behavior in groups of male lecturers female lecturers younger lecturers senior lecturers inexperienced lecturers experienced lecturers lecturers with higher than bachelors degree married lecturers groups of lectures from Rajamangala university of Technology Phra Nakhon Rajamangala university of Technology Ratanakosin Rajamangala University of Technology Krungthep. Finally the variations which are resulted from social support in groups of male lecturers female lecturers younger lecturers inexperienced lecturers experienced lecturers lecturers with higher than bachelors degree married lecturers groups of lectures from Rajamangala university of Technology Ratanakosin and Rajamangala University of Technology Rajamangala University of Technology Tawan-ok.
