The Purposes of this study were 1) to study the efficiency of childcentered approach in the faculty of mass Communication Technology Rajamangala Unuversity of Technology Phra Nakhon 2) to compare personal factors with attitude towards the efficiency of child-centeres approach in the Faculty of Mass Communication TechnologyRajamangala Unuversity of Technology Phra Nakhon 3) to study the progress of learning efficiency after the application of child-centered approach in the Faculty of Mass Communication Technology Rajamangala Unuversity of Technology Phra Nakhon and 4) to study the predicted variablesvariablespersonal factors:genderstudy areasstudent gradeschool record and attitudes towards child-centered approach. The sample taken for the investigation was a number of 300 students in academic year 2009 from the faculty of Mass Communication TechnologyRMUTP. The proportion of 300 students was considered as 50 % of all students studying in the semester 2/2009. The data were collected by questionnaires. The data were analyzed by frequency distributionpercentagemeanstandard deviationt-testF-test One-Way ANOVA and Stepwise multiple regression analysis.

This research was aimed at gaining understanding about the thoughts and beliefs embedded in the house-decorated pictures and analyzing the methods used in con-structing semiotic meaning embedded in the pictures use for decorating the houses. The sources for the study were the pictures set up to decorate the houses of the people in a comrunity in Song Phi Nong District Suphan Buri Province. The research had selected a house 10 serve as the sample for the study. The research project was inspired by the phenomenon ff using pictures to decorate the house. This phenomenon was interesting and reflecting the rotions proposed by semiotics. The findings reveal that the pictures used in decorating the house had reflected 3 beliefs: firstly social values covering the love and stronghold in the nstitutions of nation religion and monarchy and the mintenance of ones life in compliance t0 societal customs and traditions; secondly the social relationship covering the love and faith bf ancestors and; thirdly the self-presentation signifying personal life successes and adora?ion of bureaucratic rankings. Regarding the method of semiotic communication it was found that the house-decorated pictures indirectly carried the meaning. There was the use of parts to represent the whole and the use of sets of signs in the same paradigm. Another interesting rnding was the signs used in the house decoration were blended and borrowed from other tontexts to construct the meaning in a particular context as well.

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 objectives of this research are: to study the characteristics of students in the Faculty of Engineering at Rajamangala University of Technology Pra Nakorn North Bangkok Campus that influence to the risk of withdrawal from Calculus 2 for Engineers; to predict the risk of withdrawal from Calculus 2 for Engineers; and to use the results of the study for planning and solving the problems of withdrawal from Calculus 2 for Engineers. The sample is 226 students in the Faculty of Engineering at Rajamangala University of Technology who enrolled the Calculus 2 for engineers in the second semester of the academic year 2009. The data are from the questionnaire. The factors considered are grad point average the number of enrollments for the Calculus 1 for engineers Calculus 1 for Engineers grade the number of courses that emphasize on calculation that were enrolled in the second semester of the academic year 2009 the sacrifices of students for the Calculus 2 for Engineers course and the need to withdraw from Calculus 2 for Engineers course before other courses. The logistic regression model in which the parameters are estimated by using Bayesian methods is used for analyzing the data. The study shows that the factors that influence to the risk of withdrawal from the Calculus 2 for Engineers are grade point average Calculus 1 for Engineers grade the number of courses that emphasize on calculation that were enrolled in the second semester of the academic year 2009 and the sacrifices of students for the Calculus 2 for Engineers and the need to withdraw from Calculus 2 for Engineers before other courses. The factor that does not influence to the risk of withdrawal from the Calculus 2 for Engineers is the number of enrollments for the Calculus 1 for Engineers.

The species composition of Podostemaceae was studied in Loei northeastern Thailand from November 2009 to July 2010 by extensive surveying in the rapids and waterfalls inside and outside of national parks wildlife sanctuaries and protected areas. The samples collected are classified into 2 subfamilies which are Tristichoideae and Podostemoideae. The former contains 2 genera and 3 species Dalzellia kailarsenii Terniopsis sp. 1 Terniopsis sp. 2. The latter has 4 genera and 9 species Hanseniella heterophylla Hydrobryum japonicum Hydrobryum loeicum Hydrobryum tardhuangense Hydrobryum vientianense Hydrobryum sp. 1 Hydrobryum sp. 2 Polypleurum sessile Thawatchaia trilobata. The highest number of species occurs in Hydrobryum with 6 species following by Terniopsis with 2 species. The other four genera have one species each. Based on morphological and molecular analyses revealed that 2 species of the genus Hydrobryum are new and 2 taxa of Terniopsis are also new species. Polypleurum sessile and Thawatchaia trilobata are new recorded in Loei province. The result from this study indicates that the genus richness is relatively high in Loei province which encompasses 60% of the total number of genera (10) in Thailand. The plants in vegetative phase are completely submersed in swiftly running water during a warm wet season (May-October). The plants flower and set fruits and seeds when exposing to air during water level drop in a cool dry season (November- February).
