On March 30, 2026, PSPS held the Saemaul Spirit Practice Day and New Country Flag Installation Ceremony to promote the values of the Saemaul Spirit and foster a sense of belonging among students. Beginning at 7:00 a.m., approximately 100 freshmen and current students gathered wearing Saemaul vests and equipped with cleaning tools. As part of the Social Contribution Day activities, students cleaned the campus, embodying the principles of diligence, self-help, and cooperation. On the same day, the flags of four new countries—Bhutan, the Central African Republic, Namibia, and Trinidad and Tobago—were officially installed to welcome new PSPS students. The ceremony was attended by the university president, PSPS dean, faculty members, students, and administrative staff, celebrating the expansion of the PSPS global community. The event concluded with participants sharing gimbap and beverages, creating a warm and communal atmosphere.
