Desde 2 018, la violencia extrema en Ecuador aumentó significativamente. Una variable que refleja esta crítica situación es el aumento de la tasa de homicidios intencionales. Este hecho confirma la posición de Ecuador como uno de los países más violentos de Latinoamérica, la región más violenta del mundo. Según los registros policiales, diversas variables intervienen en la ocurrencia de homicidios. Por un lado, el tipo de arma utilizada para cometer un homicidio intencional juega un papel fundamental en el proceso judicial correspondiente. Por otro lado, se consideran variables explicativas relacionadas con este delito, como su tipo, ubicación, día y hora de su ocurrencia, la provincia, el género y la edad de la víctima, con el fin de estimar la probabilidad de utilizar un tipo específico de arma para cometer un homicidio intencional. Para estimarlo, desarrollamos y estimamos un modelo logístico multinomial que son parte de los modelos lineales generalizados. Los resultados ayudan a las autoridades encargadas de la seguridad ciudadana a desarrollar estrategias óptimas para prevenir, reaccionar e investigar este tipo de delito. Palabras clave: Homicidio intencional, probabilidad, multinomial, logístico, estimación.

Introduction: Online gaming has become increasingly popular among adolescents and is associated with musculoskeletal complaints, particularly affecting the thumb. Repetitive movements and poor ergonomics during gaming are key contributing factors. Methods: This quantitative, non-experimental study employed a cross-sectional design to investigate the relationship between online gaming duration and thumb musculoskeletal disorders in adolescents at STIKes RS Dustira. Independent variables included age, sex, and gaming duration, while the dependent variable was thumb pain. De Quervain’s syndrome was assessed using the Finkelstein test, performed by enclosing the thumb in the fist and deviating the wrist ulnarly. A purposive sampling technique was applied. Results: A total of 50 participants (32 males, 18 females) were analyzed, with an average daily gaming duration of 3.58 hours. The Finkelstein test was positive in 30 participants (60%), indicating thumb pain consistent with De Quervain’s syndrome, while 20 participants (40%) tested negative. Conclusion: Online gaming duration was significantly associated with thumb musculoskeletal complaints in adolescents. Preventive strategies, including ergonomic education and limiting screen time, are recommended to reduce the risk of De Quervain’s syndrome.

Children are one of the most vulnerable groups during disasters due to their limited physical and psychological resilience. Therefore, providing disaster mitigation education to children is essential to enhance their awareness, preparedness, and response capabilities in the face of potential disasters. This community service activity aims to increase children's understanding of disaster mitigation through both theoretical education and participatory simulations that reflect real-life scenarios. The activities were carried out using a cooperative-participatory approach in collaboration with the local Indonesian Red Cross (PMI) in Tanah Karo and members of the surrounding community. The stages of implementation included conducting a site survey, securing necessary permits, determining the time and location, coordinating with local stakeholders, and executing the service program. The educational activities covered disaster phases, including pre-disaster, during disaster, and post-disaster, with a focus on practical and age-appropriate learning strategies. The educational team involved an interprofessional group of facilitators who delivered the material through socialization and counseling sessions. The sessions were enthusiastically received by the children, indicating a high level of engagement and interest. However, findings revealed that children's knowledge of disaster mitigation was still minimal, emergency response plans were underdeveloped, and community involvement in disaster preparedness training remained low. This highlights the need for continuous and sustainable disaster education efforts, especially for children and communities in disaster-prone areas. By fostering early awareness and preparedness through ongoing education and simulation-based activities, it is expected that children will be better equipped to respond effectively and safely during disaster situations. Long-term, this approach also aims to build a more resilient and disaster-aware community.

Spektrometer werden in der Arzneimittelproduktion immer häufiger zur Prozesskontrolle eingesetzt. Ein führender Pharmahersteller hat ein NIR‐Spektrometer in einen speziell entwickelten, mobilen Steuerschrank integrieren lassen, der explosionsgeschützt ist. Diese Lösung ermöglicht es, das hochwertige Spektrometer flexibel an verschiedenen Orten einzusetzen und die Qualität der Medikamente in Echtzeit zu überwachen. Dies spart Zeit und Kosten und erhöht die Effizienz in der Produktion.

For years the Eddy currents principle together with inductive thermography have been applied to detect cracks or defects in metallic machine components. In case a component has a crack, by inducing Eddy currents within a coil, it is possible to cause a temperature increase in the edges of the crack. This temperature variation can be observed by using an infrared camera. Thus, the crack is registered and observed in the infrared images, which are later analyzed. However, currently used systems require an enormous amount of power and a long time for image processing. For this reason, applying this method to large steel structures such as bridges, cranes, wind power towers, pipe lines or offshore oil stations has been much more complex. To overcome these limitations, a light portable system that optimally recreates the Eddy currents principle has been developed and used in this research. This system generates a square wave AC voltage, it uses considerably less power and it is capable of detecting cracks in real time. This paper presents the simulations and experiments carried out on two different structural steel specimens to demonstrate the efficiency of the system and its potential in the field of nondestructive testing.

The prevalence of broken homes, characterized by parental separation, divorce, or single-parent households, poses significant challenges to adolescents' development and academic outcomes. This research explores the intricate relationship. Through a mixed-methods approach encompassing quantitative surveys and qualitative interviews, the study examines the mechanisms through which family disruptions influence academic functioning among adolescents. Quantitative analyses reveal significant associations between broken home conditions and lower levels of attentional control, task persistence, and academic engagement among adolescents. These findings persist even after controlling for demographic variables such as socioeconomic status and parental involvement, underscoring the independent contribution of family disruptions to academic outcomes. Qualitative insights provide rich contextual understanding of the lived experiences of adolescents in broken homes, highlighting the emotional turmoil, insecurity, and challenges they face in navigating academic demands amidst familial upheaval. The implications of these findings are far-reaching, with significant implications for educational practice, policy, and intervention efforts. By recognizing the unique needs of adolescents from broken homes and developing evidence-based strategies to support their holistic development and academic success, educators, policymakers, and stakeholders can create nurturing and inclusive environments where all adolescents have the opportunity to thrive.
