Yayın The development of a hybrid cutting model for workpiece temperature distribution via advection heat partition approach(Springer Science and Business Media Deutschland GmbH, 2023-04-15) Kara, Mehmet Emre; Kuzu, Ali Taner; Bakkal, MustafaThis paper presents a novel hybrid cutting model for the prediction of workpiece temperature distribution during the dry milling process of compacted graphite iron (CGI). The hybrid model consists of an analytical force model based on a mechanistic approach and finite element analysis (FEA) based on the thermal model. The heat generated during the milling process transferred to the workpiece is computed via the advection heat partition model. The workpiece temperature distribution obtained through the heat loads, using as boundary conditions in the FEA, was calculated by means of cutting forces. The developed force and thermal models have been experimentally validated, and good agreement between the measured and calculated results has been observed. The energy and active work calculations show that by doubling the feed during CGI milling, an energy saving of about 10% is achieved despite almost doubling the cutting forces.Yayın Examining psychological resilience and posttraumatic growth following terrorist attacks in Turkey(American Psychological Association, 2021-06) İkizer, Gözde; Özel, Ebru PelinActs of terrorism, being highly prevalent across the world, disrupt community and social functioning and can lead to negative psychological reactions in individuals. However, positive outcomes can also be evoked after adverse experiences. The current study aimed to explore two salutogenic or positive outcomes—resilience and posttraumatic growth (PTG)—following exposure to terrorist attacks. The sample included 331 university students who were exposed to a terrorist attack in Turkey during the last 18 months prior to data collection. Participants responded to the Connor-Davidson Resilience Scale, the Posttraumatic Growth Inventory, and a participant information form. The relationship between resilience and PTG was examined through correlation analysis and regression analyses with linear and quadratic components. Resilience and PTG were positively correlated. Tendency toward spirituality was the only resilience domain that was significantly correlated with all domains of growth. Total score of resilience was significantly associated with scores on all subscales of the Posttraumatic Growth Inventory except appreciation of life. Results indicated that only linear relationships existed between domains of resilience and PTG in the study sample. The positive and linear association between resilience and PTG suggests that resilience may be an important tool for facilitating growth. After terrorist attacks, mental health care planning should adopt a patient-centered approach that acknowledges the possibility of positive outcomes following traumatic events and focuses on the impact as well as recovery phases in traumatized individuals.
