The research was conducted to study on effects of environmental management in evaporative cooling system (EVAP) house on productive performance of layer pullets. This study divided into 2 experiments. Experiment 1 was conducted to study on temperature and air velocity in evaporative cooling system (EVAP) house on productive performance of layer pullets. Four thousand and eight hundred layer pullets were raised on battery cage with 5 birds per cage and assigned in a Randomized Completely Block Design (RCBD) experiment with three treatments. Each treatment consisted of four blocks (four houses) and followed different temperature and air velocity in raising area of evaporative cooling system (EVAP) house as front area central area and back area. Results showed that temperature and air velocity in front area was grater body weight gain (BWG) average daily gain (ADG) and feed conversion ratio (FCR) of layer pullets than layer pullets were raised in back area of evaporative cooling system (EVAP) house (P<0.01) Experiment 2 was conducted to study on light color and number of H-Flame battery cage row in evaporative cooling system (EVAP) house on light intensity and productive performance of layer pullets. Nine thousand and six hundred layer pullets were raised on H-Flame battery cage with 5 birds per cage and assigned in a 2x4 factorial in Randomized Completely Block Design (RCBD) experiment with two factors. Factor A was light color comprised of range and blue). While Factor B was number of battery cage row comprised (first row second row third row and fourth row). Each treatment consisted of four blocks (four houses). Results showed that interaction between factor A and B on light intensity and uniformity of layer pullets with highly significantly different (P<0.01). However interaction between factor A and B and main effect (factor A and B) were investigated on body weight gain (BWG) average daily gain (ADG) and feed conversion ratio (FCR) (P>0.05). The data from this research was suggests the important for implicate to improve the egg production industry in further success.

The objectives of this research were: 1) to study teachers opinions towards environmental management in private kindergarten schools and 2) to compare teachers opinions towards environmental management classif ied by gender age education and teaching experiences. Sample consisted of 136 teachers sampling from 85 private kindergarten schools under the Off ice of Private School Promotion Commission Bangkok Education Service Area. The instrument used was a rating scales questionnaire. Data were analyzed by computer program for percentage mean standard deviation and t-test was used for hypothesis testing (independent samples). Results showed that teachers opinions towards environmental management of private kindergartens in overall physical and social environmental management were at high level. A comparison of teachers opinions according to gender age education and teaching experiences showed no difference.

This research is a survey research. The purpose was to study the realization of environmental ethics of Rajamangala University of Technology Phra Nakhon students towards the refuse disposal problem and analyzing the factor that influence their realization of environmental ethics. The subject for this research was randomly selected form the undergraduate student of Rajamangala University of Technology Phra Nakhon in the academic year 2007 by using the simple random sampling technique. The instruments used in this research were questionnaires. The data was analyzed by percentage mean standard deviation and Hest. The research found out that the students had a high level of the realization of environmental ethics about 49.47 percent. About 30.37 percent had a medium level and about 19.30 percent had a low level. Gender did not difference in realization with statistical significance at.05. The factor that influence their realization of a high level environmental ethics were age about 18 -20 year old occupation of parent was governors a monthly income of 5001 -8000 baht the education level finished undergraduate. The respondents were received environmental information. Habitat and gender did not make the difference in their realization.

The purpose of this study was to study the some factors related to attitude in environmental pollutions of students and compare attitude in environmental pollutions of students in faculty of business administration at Rajamangala University of Technology in Bangkok in 6 aspects : environmental pollutions water pollution air pollution noise Pollution toxic substances pollution and solid waste pollution. The students were classified by gender academic years and major subjects. The samples in this research were 1745 students. The study participates were selected by stratified random sampling. The 30 item tests and 42 item questionnaires of Likerts rating scales were used as the research instrument. Percentage mean standard deviation t -test for independent sample F -test LSD analysis and multiple correlation (stepwise multiple regression analysis) were statistical methods to analyze data. The results were as follows: 1.Attitude in environmental pollutions of students all aspects were in agreeable levels that noise pollution was the highest while environmental pollutions and water pollution was in the lowest rank. 2.Media exposure about environmental pollutions of students were in middle level that friend and television was the highest. 3. There was significant difference for media exposure about environmental pollutions at the 0.05 level among students in different gender and different major subjects. 4. There was significant difference for knowledge about environmental pollutions at the 0.05 level among students in different gender different academic years and different major subjects. 5. There was significant difference for attitude in environmental pollutions at the 0.05 level among students in different gender different academic years and different major subjects. 6. The score -weight of knowledge about environmental pollutions and media exposure about environmental pollutions contributed to attitude in environmental pollutions of students with statistically significant at 0.01 level and then media exposure about environmental pollutions contributed to attitude in environmental pollutions of students higher than knowledge about environmental pollutions.

This survey research aimed to study the realization of environmental ethics of Rajamangala University of Technology Phra Nakhon students towards the refuse disposal problem and to analyze the factors that influence their realization of environmental ethics. The subject for this research was randomly selected from the undergraduate students. The instruments used in this research were questionnaires. The data were analyzed by percentage mean standard deviation and t-test. The research was found that 49.47 percent of the students had a high level of the realization of environmental ethics 30.37 percent had a medium level and 19.30 percent had a low level. Gender is not different.
