Identifying the coping mechanisms practiced by the medical students is of importance and must be explored to promote healthy stress coping methods. Hence, a descriptive cross-sectional study was undertaken with a sample of 410 medical students from a State Medical School in Sri Lanka. The research question of the study focused on identifying the different coping methods practiced by medical students. A questionnaire with 2 parts, A and B, was used to collect data on stress coping methods used by the study participants. The study also obtained data on the effectiveness of popular stress coping methods from the users. The responses for the questions in part A showed a trend of positive outlook in all general aspects of life except for one question, which directly questioned the ability of students to cope with stress imposed by the academic programme. Based on the results from part B of the questionnaire, the most common and widely used stress coping mechanisms included sleeping, listening to music and talking with friends and family. Effective coping strategies identified to minimize stress were religious activities like praying/worshiping and meditation. Moreover, seeking advice from lecturers, seniors, going home and engaging in sports and games were also found to be effective in lessening stress. In conclusion, facilities for students to involve in religious activities such as prayers and meditation shall be available in the Faculty. Getting counseling and involving in sports also appear to alleviate stress and these should be integrated into the life of medical students.

Constant prey refuge with immigration and harvesting in two species would result in significant diversity in the dynamics of a prey–predator population. The phrase “refuge” increases the likelihood of prey population survival in the face of a predator population. Based on these findings, we created and examined a two-species prey–predator system with immigration and harvesting factors, including refuge to only prey population. All ecologically possible equilibrium points are studied for the proposed system. Routh–Hurwitz stability criterion is used for local stability analysis. Global stability of the interior equilibrium point is examined with a suitable Lyapunov function. Local bifurcation of the proposed system, such as saddle-node bifurcation, is analyzed. The conditions for the emergence of this bifurcation at the critical threshold near the nonhyperbolic equilibrium point are established by utilizing Sotomayor’s theorem. The transversality condition is validated for the occurrence of Hopf-bifurcation. The first Lyapunov number is exploited for determining the nature of Hopf bifurcating periodic solution. Finally, numerical simulations are illustrated to validate our theoretical predictions.
