This study examines Thailands domestic and export market situation with regard to rubber smoked sheet no.3 (RSS3). Time series analysis is used to estimate trends in order to forecast the export of RSS3 during January 2557 – December 2561 using monthly data from 2542 – 2556. The results show that export volume of RSS3 is likely to increase every year in the same month. The volume of exports in December in every year is the most abundant. However as the volume of product increases every year the rubber price keeps falling. As a result farmers and entrepreneurs would benefit from government expansion of the market by the establishment of a domestic industry as an alternative support for output rather than sole reliance on export.

The aim of this research was to study the solid waste management in Faculty of Science and Technology Rajamangala University of Technology Phra Nakhon study problems and obstacles of the solid waste management. The study will benefit related organizations as fundamental information for setting plans on the solid waste management to ensure the maximum efficiency and expand to other faculties. In this study a researcher collected quantitative data and also characteristics of solid waste occurred. Total amounts of solid waste were approximately 20.86 kilograms per day. Types of solid waste mostly found were reuse /recycle wastes (10.21 kilograms per day) and organic wastes (10.43 kilograms per day). The results showed an information for developing solid waste management under 3R processes (Reduce Reuse and Recycle) lead to sustainable solid waste management and efficiency.

For this work PM10 were collected from 7 stations within the area of North Phra Nakhon campus Rajamangala University of Technology Phra Nakhon Thailand. The samples were collected within 24 hours from January to April 2015. The result shows that the concentrations of PM10 values are in the range of 0.06 - 0.16 mg/m3 and average PM10 of 0.09 mg/m3. The maximum PM10 were found in front of the university. The comparison of maximum PM10 with the standard value of Pollution Control Department (PCD) was slightly over but did not affect human health.

The aim of this work was to study the magnetic properties of magnetic glassceramics with composition system CaO-Na2O-P2O5-BaO-Fe2O3. The magnetic glass– ceramics were prepared by conventional melting at 1300oC for 2 h of the coprecipitation derived starting products and heat treated at different temperatures. The structure and microstructure of the samples were characterized by X-ray diffraction energy dispersive X-ray analysis (EDXA) and scanning electron microscopy. The magnetic measurement showed that the samples which contained barium ferrite exhibited magnetic behavior which is similar to soft magnetic materials. Finally the samples were soaked in simulated body fluid (SBF) for 14 days. The apatite was found to form on the surface layer of glass-ceramics and it increases with the barium ferrite content was increased.

The survey research aimed to: 1) study the levels of self-development needs in preparation to enter AEC; 2) make a comparison of the students’ needs levels in aspects of personal data; and 3) propose appropriate forms of activities to be used in the development. The subject obtained through stratified random sampling consisted of 321 first-fourth year undergraduates of the Faculty of the Home Economic Technology Rajamangala University of Technology Phra Nakhon. The tool was a questionnaire. To analyse data the frequency percentage mean standard deviation t- test and ANOVA were used. The results were as follows: 1) The overall level of self-development needs was high ( X = 3.75). The needs for selfdevelopment in line with the Thai Qualifications Framework for Higher Education were high ( = 3.89). Moreover the level of needs conforming to Thai Graduate Preferable Qualifications for the ASEAN Community was moderate ( X = 3.46). 2) There was no statistically significant difference ( p<0.05) of the self-development needs level when genders educational levels or academic performances were considered 3) As for the activities it was rated best to use training for the development of cognitive skills numerical analysis communication and information technology skills domain of psychomotor skills and knowledge on ASEAN Community rules and regulations; lecturing for knowledge on ASEAN Community rules and regulations; study touring for knowledge development; camping for ethics and moral interpersonal skills responsibility and language skills; and student inter institutional exchanging for neighbouring countries knowledge development.
