Effects Of Intergroup Ideologies On Willingness To Engage In Intergroup Contact With Essentialism As A Mediator, Piraorn Suvanbenjakule

Chulalongkorn University Theses and Dissertations (Chula ETD)

Various studies have found that merely interacting with an outgroup does not necessarily lead to better intergroup relations. The prejudice against Myanmar in Thailand is still an issue that needs solving. Therefore, cultures should be understood as an ongoing process in the hope that it would be more consistent with the current social environment and improve intergroup relations. The first study was a cross-sectional study that examined the self-reported scores of polyculturalism and the willingness to engage in intergroup contact with essentialism as a mediator. The online survey was distributed, and 112 high-school and university students were included in the …

Chulalongkorn University Theses and Dissertations (Chula ETD)

Regeneration of damaged periodontal tissues becomes one of the biggest challenges that is hard to overcome, even without the presence of any pathogens. Tissue engineering was proposed as a possible technique for the lost tissues’ restoration. In this study, methacrylated hyaluronic acid (MeHA) hydrogel was developed with different concentrations of low molecular weight (short-chain) hyaluronic acid to achieve the hydrogels with suitable physical properties and biological properties for dental tissue regeneration. The results revealed that short-chain hyaluronic acid (sHA) could interfere with some behaviors of networking systems; however, overall properties (including gelation time, mechanical properties, swelling and degradation profiles, and …
