The purposes of this research were to (1) investigate factors which have impacts on working-age people’s decision making to save money in Bangyai district Nonthaburi Province (2) study working-age people’ behavior in decision making to saving money in Bangyai district Nonthaburi Province (3) compare the importance of factors that affect to the working-age people’s decision making in saving money in Bangyai district Nonthaburi Province.The sample of the study consists of 400 people (ages 20-60 years old). The research instruments used for data collection were the questionnaire. The reliability data were analyzed by using frequency percentage means and standard deviation of t-test (Independent t-test) F-test (Independent sample F-test) and Content Analysis. The results of the study revealed that: The mainly respondents are female being over 30-40 years old having single status and education background in bachelor degree. Moreover the respondents are working as an employee of the private company the average income per month over 10000-20000 baht and family members around 3-4 people. The respondents pointed out similar saving money to use after retirement and deposit with banks in short term saving. The respondents will spend first then keep the rest of the money to saving and they have money savings less than 10%. The working-age people’s decision making to save money in Bangyai district Nonthaburi Province was at a moderate level. Two factors of decision to saving (1) income from savings and (2) saving characteristics were at a high level. Besides four factors of decision to saving (1) security (2) yield upon investment (3) incentives for saving and (4) social and economy were at a moderate level. There was low positive statistical significant relationship between the differences of age marital status education level occupation average monthly income family members purposes of saving savings schemes and factors affecting working–age people’s decision to saving at 0.05 However the respondents who have the differences of gender period of saving saving method and saving ratio focused on the factors of decision to saving at no difference.

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.
