This research presents a study of the resistance to carbonation compressive strength and porosity of concrete containing ground bottom ash. Three different of bottom ash finenesses viz. coarse bottom ash (GBA-1) ground medium bottom ash (GBA-2) and ground fine bottom ash (GBA-3) were used for the study. Portland cement (CT) is partially replaced with ground bottom ash at 0-40% by weight of the bottom ash. The water to binder ratio was kept constant at 0.5. Compressive strength porosity and resistant to carbonation of concrete were investigated. Fine bottom ash has a high potential to be used as a good cementitious material. The results show that the compressive strength and low porosity of concrete improves substantially with partial replacement of Portland cement with fine bottom ash. Concrete mix cement containing 10-20% of fine bottom ash can be used to make cementitious materials. The use of finer bottom ash produces concrete mix with good strength and resistance to carbonation.

The objectives of the research are to study and compare the desirable characteristics of Home Economics graduates in the field of fresh flora decoration to study the problem and suggestion according to the requirement of the three stars and four stars hotel located in Bangkok and registered with the Thai Hotel Association by using the questionnaires with 34 samples using the percentage mean standard deviation and t – test as the analysis tools.

The purpose of This research were 1) To design clothes in type of folding clothes in bag styles; 2) To study the consumers’ satisfaction of folding clothes in bag styles; 3) To compare the result of consumers’ satisfactory of folding clothes in bag styles. Starting from of 30 styles of clothes sketching and 30 styles of bags sketching and selecting 8 sketches of clothes and 8 sketches of bags by specialist. Then the researcher matched 8 sets of clothes and bags and improve appropriately the clothes and bags pattern for clothing construction. To survey satisfaction of consumers with questionnaires from 300 women consumers sampling in Siam Square Area Bangkok metropolitan in the year 2011. The data statistics were analyzed mean frequency percentage standard deviation one-way ANOVA and T-test. The result was summarized in the table form and description.

There are two purposes of this research 1) the level of knowledge and attitude in ecotourism of student in Rajamangala University of Technology Phra Nakhon 2) the ecotourism behavior of student in Rajamangala University of Technology Phra Nakhon. The study was conducted by analyzing questionnaires collected from sample of student in Rajamangala University of Technology Phra Nakhon total 430 cases. The SPSS was used to analyze these questionnaires. Descriptive Statistic were applied and presented in form of percentage and mean. The research showed that 1.The respondents were most males they were sophomore studied in Business frequency of travel ecotourism is between 1-2 times / year. They get information from television/radio the most. 2.The level of knowledge in ecotourism was high especially for Eco-tourism focused on nature and the environment. The unique biological habitats and artistic traditions as possible. 3.The level of attitude in ecotourism was high especially for Eco-tourism management should take into account the potential of existing resources and activities accordingly. 4.The ecotourism behavior was medium-high especially for When you see wild animals are crossing the road. You stop waiting for the animals go through before.

The purposes of this research were to study and to compare the ethics of the first-year students at Rajamangala University of Technology Phra Nakhon who were from Bangkok with the ethics of the ones from other provinces. The samples chosen by purposive sampling were the first-year English for International Communication students of the Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. They were divided into 2 groups and each group consisted of 30 students. The first group was from Bangkok while the second group was from other provinces. The instrument was a questionnaire. The results revealed that there was no significant difference (at the level of .05) of the ethics of the first-year students who were from Bangkok and of those from other provinces. The mean scores and standard deviations of the results of the first group were 3.82 and 0.34 and of the second group were 3.89 and 0.34 respectively.
