Influences of Psychological Resilience and Self-control on Suicidal Ideation of Undergraduate Students / 정신간호학회지

PURPOSE: The study was done to examine undergraduate student' suicidal ideation and to identify influences of individual characteristics including psychological resilience and self-control on suicidal ideation. METHODS: Data were collected from 400 students in 11 universities in D city from May 1 to June 30, 2011. Data were analyzed with t-test, one-way ANOVA and Pearson' correlation using SPSS 19.0. RESULTS: Of the students, 11.3% reported suicidal ideation levels higher than average. Woman students and those with high career anxiety, perceived poor health condition and bad relationships showed higher points on suicidal ideation. Suicidal ideation was also negatively correlated with psychological resilience and self-control. CONCLUSION: Over 10.0% of students need careful attention on suicidal ideation, especially counselling service related to suicide prevention for students with poor health, high career anxiety, and bad relationships. Various programs should be developed to promote psychological resilience to improve health and relationships, as well as job guidance for students. It is also suggested the students' experiences be examined to determine how they overcame suicidal ideation.

Effects of Ovarian Cycle on Hemodynamic Responses during Dynamic Exercise in Sedentary Women

This study tested the hypothesis that effects of the menstrual cycle on resting blood pressure carry over to dynamic exercise. Eleven healthy females were studied during the early (EP; low estrogen, low progesterone) and late follicular (LP; high estrogen, low progesterone) menstrual phases. Stroke volume (SV), heart rate (HR), cardiac output (CO), systolic blood pressure (SBP), diastolic blood pressure (DBP), and total vascular conductance (TVC) were assessed at rest and in response to mild and moderate cycling exercise during EP and LP. During EP, compared to LP, baseline SBP (111+/-1 vs. 103+/-2 mmHg), DBP (71+/-2 vs. 65+/-2 mmHg) and mean arterial pressure (MAP) (84+/-2 vs. 78+/-1 mmHg) were higher and TVC (47.0+/-1.5 vs. 54.9+/-4.2 ml/min/mmHg) was lower (p<0.05). During exercise, absolute values of SBP (Mild: 142+/-4 vs. 127+/-5 mmHg; Moderate: 157+/-4 vs. 144+/-5 mmHg) and MAP (Mild: 100+/-3 vs. 91+/-3 mmHg; Moderate: 110+/-3 vs. 101+/-3 mmHg) were also higher, while TVC was lower (Mild: 90.9+/-5.1 vs. 105.4+/-5.2 ml/min/mmHg; Moderate: 105.4+/-5.3 vs. 123.9+/-8.1 ml/min/mmHg) during EP (p<0.05). However, exercise-induced increases in SBP, MAP and TVC at both work intensities were similar between the two menstrual phases, even though norepinephrine concentrations were higher during LP. Results indicate that blood pressure during dynamic exercise fluctuates during the menstrual cycle. It is higher during EP than LP and appears to be due to additive effects of simultaneous increases in baseline blood pressure and reductions in baseline TVC.
