While some research has indicated the relationship between participation in social development activities (PSDA) and perceived social support (PSS) with problematic smartphone use (PSU), there has been a lack of studies examining these relationships through the lens of the flourishing theory, particularly among adolescents. To address this gap in the literature, this study conducted between April and May 2022 included 4965 high school students from 20 different cities in Türkiye. Researchers utilized questionnaires assessing participants' demographic information, levels of participation in social development activities, The Smartphone Application-Based Addiction Scale, The Short Version of the Scales of General Well-Being (GWB), and The Multidimensional Scale of Perceived Social Support as instruments.

Article Synopsis
  • Tuberculosis, caused by Mycobacterium tuberculosis, is a significant global health issue, and rising drug resistance highlights the urgent need for new treatments.
  • Computer-aided drug design (CADD) is being utilized to create more effective and less toxic drugs for tuberculosis.
  • The study focused on two synthetic peptides, AKVUAM-1 and AKVUAM-2, which were designed to block interactions crucial for M. tuberculosis infection, showing promise without harming normal lung tissue and having varied minimum inhibitory concentrations (MIC) against different bacterial strains.

Obsessive Compulsive Disorder (OCD) is characterized by problems of control over behavior and cognition. Although almost all of the studies on pathogenesis of OCD point out fronto-striatal dysfunction, it is still not possible to reveal mechanisms to explain the entire clinical course of OCD through these circuits. A more holistic explanation can be given through the Embodied Cognition (EC) perspective, which suggests that the alteration/dysfunction of low-level sensory-motor process may appear as a multifarious extent of dysfunction of high-level cognitive processes.

Background: Cluster analysis is a robust tool for exploring the underlining structures in data and grouping them with similar objects. In the researches of Functional Magnetic Resonance Imaging (fMRI), clustering approaches attempt to classify voxels depending on their time-course signals into a similar hemodynamic response over time.

Objective: In this work, a novel unsupervised learning approach is proposed that relies on using Enhanced Neural Gas (ENG) algorithm in fMRI data for comparison with Neural Gas (NG) method, which has yet to be utilized for that aim.

Introduction: Action naming is reported to be more damaged in patients with schizophrenia than object naming. Aim of this study is to understand the cortical mechanism underlying the negative symptoms seen in patients with schizophrenia such as inactivity, restricted behavioral repertoire, by using functional MRI (fMRI) to determine whether the action origin words have a different representation in the brain regions of patients with schizophrenia and healthy individuals. Our hypothesis is that restriction in the repertoire of movement and behavior and the failure of words of "action" than words of "object" are interrelated through the same cortical mechanisms.
