Under the reasonableness pillar, the waste management, following the sufficiency economy philosophy, found
the accessibility to information of the philosophy was statistically significant different at 0.01. This indicated that
television, radio, magazines, and family members had a higher average value than other media such as internet
(Phetreunthong, 2007). However, the overall average value of waste management in Pha-Yot Mueang Kwang fort
under the reasonableness pillar was indifferent. This implied that any media in the information technology world can
play a major role in influencing people behaviours as long as the information are trustworthy, easy, and fast enough
to reach to those people. For Pha-Yot Mueang Kwang fort, the media would include television and radio,
particularly the line radio sound system, aired every morning. Information from those media contain contents such
as the important policies, practical guidance for troops, health information and news, which are useful for the troops.
This study also suggests that since mostly the troops were at the average age of 45, the ability to obtain the
information through the internet might be limited. Therefore, to reach to the vast majority of the troops, knowledge
about the philosophy of sufficiency economy and waste management should rather be included through media such
as television and radio.
