The relationship between problematic smartphone use and psychiatric symptoms among adolescents who applied to psychiatry clinics

Problematic mobile phone use is an important problem which has increasing prevalence among adolescents. We should address risk factors to create intervention frameworks related to this problem. In this study, we aimed to determine the prevalence of problematic smartphone use among adolescents who were referred to clinics, its relationship to sociodemographic characteristics, psychiatric symptoms and emotion regulation problems. We included 150 adolescents aged 12–18 years who own smartphones. All participants filled out the Sociodemographic Information Form, Brief Symptom Inventory (BSI), Difficulties in Emotion Regulation Scale (DERS) and Problematic Mobile Phone Use Scale (PMPUS). Problematic smart phone use was detected in 50.6% of the sample. Adolescents with problematic use were found to be older than the others, with lower levels of maternal education and self-achievement. Regression analysis revealed that the factors predicting the risk of problematic smartphone use are somatization, interpersonal sensitivity and hostility symptoms. According to our results, we suggest psychiatrists consider the high prevalence of problematic smartphone use, address the relationship between hostility, somatic symptoms and interpersonal sensitivity (susceptibility) and the effects of this current problem on social-academic functioning while evaluating and treating adolescents

Problematic whatsApp use among adolescents: linking fear of missing out and psychiatric symptoms

Objective: WhatsApp (WA) is the most popular instant message application all over the world. Although communication has become easier and enjoyable with the help of this application, the overuse, and addiction of WA has become an important problem among adolescents. WhatsApp addiction is a part of problematic smartphone use (PSU). When we examined previous studies, we found that the samples were generally composed of young adults, but studies on adolescents who are at high risk for problematic Whatsapp use (PWU) were insufficient, and almost no studies were conducted in the clinical adolescent sample. In this study, we aimed to increase our knowledge about problematic PWU and possible risk factors including fear of missing out (FoMO), PSU, and psychiatric symptoms among adolescents who applied to outpatient psychiatry clinics.Methods: 197 adolescents (136 boys, 61 girls, age: 12-18 years) recruited the study. Problematic Mobile Phone Usage Scale (PMPUS), Bergen Whatsapp Addiction Scale, Brief Symptom Inventory, and Fear of Missing Out (FoMO) Scale were used.Results: We grouped the sample as PWU (Problematic WhatsApp use) and Normal Use group due to Bergen WA Addiction Scale. PWU group’s adolescents were significantly older than others (p=0.03), and had higher scores in all subscales of Brief Symptom Inventory (BSI), FoMO and PMPUS (for all scale scores p<0.001). Regression analysis demonstrated that FoMO is a predictor of PWU. Also, paranoid ideation, psychoticism, phobic anxiety, and somatization had a positive effect (ß=1.80, 0.98, 1.26, 0.52; respectively) while obsession compulsion and depression had a negative effect on PWU (ß=-0.76, – 1.22, respectively).Conclusion: Our results demonstrated that problematic Whatsapp use is an important internet-related behavioral problem and have specific risk factors among adolescents. Adolescents use Whatsapp generally with their real friends/relatives. Adolescents who have depression, obsession-compulsion mostly have social withdrawal, and would not be interested in communicating their real social environment. On the other hand, adolescents who have phobic anxiety, paranoid ideation, psychoticism and somatization symptoms would follow the changes and events more closely. The associations between different psychiatric symptoms and PWU could guide the practitioners in the psychiatric care of adolescents

Two-Frequency Jahn-Teller Systems in Circuit QED

We investigate the simulation of Jahn-Teller models with two non-degenerate vibrational modes using a circuit QED architecture. Typical Jahn-Teller systems are anisotropic and require at least a two-frequency description. The proposed simulator consists of two superconducting lumped-element resonators interacting with a common flux qubit in the ultrastrong coupling regime. We translate the circuit QED model of the system to a two-frequency Jahn-Teller Hamiltonian and calculate its energy eigenvalues and the emission spectrum of the cavities. It is shown that the system can be systematically tuned to an effective single mode Hamiltonian from the two-mode model by varying the coupling strength between the resonators. The flexibility in manipulating the parameters of the circuit QED simulator permits isolating the effective single frequency and pure two-frequency effects in the spectral response of Jahn-Teller systems.Comment: 8 pages, 4 figures, figures revise

Green carbon dots from poppy seeds with conjugated hydrogel hybrid films for detection of Fe3+

A simple, non-toxic and eco-friendly method has been developed for detection of Fe3+ using the beneficial plant Opium Poppy (Papaver somniferum) seeds as a carbon source to fabricate a hybrid film (HF). The hybrid film platform comprises of quince seed mucilage and sodium alginate to form a fluorescent hybrid film with green carbon dots derived from poppy seeds (P-CDs). All materials and methods contain non-toxic chemicals. The prepared samples have been characterized morphologically, structurally and optically by spectroscopic techniques. A hydrodynamic radius of the P-CDs is determined as an average of 4.79 nm using Dynamic Light Scattering (DLS). It has been identified that hybrid film is selective towards Fe3+ ions among different metal ions with one-step by the naked-eye and turn-off detection and selectivity of P-CDs to Fe3+ is determined by fluorescence measurement. The detection limit (LOD) of Fe3+ ion is found as 0.356 mM. Developments of such a hybrid material from sustainable and low-cost sources make it an interesting option as a detection material must be investigated in various fields. For the first time, quince seed mucilage combined with green carbon dots and it has been studied in the detection field as a hybrid film. This study has proven that biotechnological studies about carbon dots can also obtain efficient results by providing green, economic, energy and water saving approaches

Importance of Grass Carp (Ctenopharyngodon idella) for Controlling of Aquatic Vegetation

Aquatic plants are beneficial and a necessary part of lakes and reservoirs. Also, some kind of plants are the main food source for aquatic animals. Plants are able to stabilize sediments, improve water clarity and add diversity to the shallow areas of lakes. On the other hand, overgrown plants can become a nuisance by hindering human uses of water and threaten the structure and function of diverse native aquatic ecosystems. This chapter aims to make analysis of using of grass carp to control aquatic vegetation. In this concept, origin and distribution, biological features, reproduction, feeding behaviour and effects of grass carp on aquatic plants, water body and sediments are also discussed

Unusual Suspect After Spinal Anesthesia: Herpetic Encephalitis

Herpes simplex virus (HSV) is the most common cause of acute, sporadic viral encephalitis. Usually occurs with the activation of the latent virus. Sudden onset fever and especially temporal lobe involvement are typical clinical features of HSV encephalitis. In this article, we aimed to present a case of herpetic encephalitis, which is an unusual factor in meningitis after spinal anesthesia. Severe headache and convulsion developed at postoperatively. Body temperature of the patient was 38.3 °C and neck stiffness developed. The patient was diagnosed with herpes encephalitis by clinical, laboratory and cranial magnetic resonance, and acyclovir treatment was started immediately. The patient was discharged home with recovery on the 14th day. Loss of consciousness and convulsions with fever seen at the postoperative period after spinal anesthesia, may not always be due to bacterial meningitis but sometimes due to HSV-associated acute herpetic meningoencephalitis. Rapid diagnosis and treatment is life-saving

Attractive versus Repulsive Excitonic Interactions of Colloidal Quantum Dots Control Blue- to Red-Shifting (and Non-shifting) Amplified Spontaneous Emission

Tunable, high-performance, two-photon absorption (TPA)-based amplified spontaneous emission (ASE) from near-unity quantum efficiency colloidal quantum dots (CQDs) is reported. Besides the absolute spectral tuning of ASE, the relative spectral tuning of ASE peak with respect to spontaneous emission was shown through engineering excitonic interactions in quasi-type-II CdSe/CdS core/shell CQDs. With core shell size adjustments, it was revealed that Coulombic exciton-exciton interactions can be tuned to be attractive (type-I-like) or repulsive (type-II-like) leading to red- or blue-shifted ASE peak, respectively, and that nonshifting ASE can be achieved with the right core shell combinations. The possibility of obtaining ASE at a specific wavelength from both type-I-like and type-II-like CQDs was also demonstrated. The experimental observations were supported by parametric quantum-mechanical modeling, shedding light on the type-tunability. These excitonically engineered CQD-solids exhibited TPA-based ASE threshold as low as 6.5 mJ/cm(2) under 800 nm excitation, displaying one of the highest values of TPA cross-section of 44 660 GM

Koncentracije haptoglobina, serumskog amiloida A i ceruloplazmina u goveda sa sumnjom na zaraznu koricu goveda

The aim of this study was to determine haptoglobin (Hp), serum amyloid-A (SAA) and ceruloplasmin (Cp) levels in naturally occurring cases of coryza gangrenosa bovum (CGB). The study was conducted on 14 animals, where 7 were sick cattle clinically diagnosed with CGB (patient group), and 7 healthy cattle from the same region (control group). It was determined that the general clinical examination results (rectal temperature, heart and respiratory frequency and rumen movement) detected in the patient group of animals showed significant differences (P0.05). Consequently, serum SAA and Hp concentrations in the cattle with CGB infection increased significantly in the acute phase of the disease, and it was concluded that further in-depth studies should be conducted on more animals in order to reveal the clinical significance of these changes in CGB infections, and also for precise diagnosis of CGB.Istraživanje je poduzeto s ciljem određivanja razine haptoglobina (Hp), serumskog amiloida A (SAA) i ceruloplazmina (Cp) u goveda oboljelih od zarazne korice. Provedeno je na 14 životinja od kojih je sedam bilo s kliničkom slikom bolesti, a sedam kontrolnih iz istog područja kao i oboljele. Nalazi opće kliničke pretrage (mjerenje temperature, frekvencija bila i disanja te kontrakcije buraga) u skupini bolesnih životinja bile su signifikantno veće (P0,05). To govori da su koncentracije serumskog SAA i Hp u goveda sa sumnjom na zaraznu koricu bile značajno veće u akutnoj fazi bolesti. Potrebno je poduzeti daljnja istraživanja na većem broju životinja da bi se utvrdilo kliničko značenje spomenutih promjena kod zarazne korice goveda što bi također bilo od važnosti za postavljanje točne dijagnoze te bolesti

Tourist lifestyle: Food and travel activities at a gastronomy destination in Türkiye through the mediating role of destination familiarity

This work aims to determine the effect of the travel preferences of domestic and foreign tourists visiting Gaziantep province in Türkiye and their participation in destination food and travel activities, as well as examining the mediating role of destination familiarity. The research model includes three sub-factors for travel lifestyle: preference for proximity and comfort, interest in new and local culture, and preference for activities and adventures. While preference for destination food activities has two sub-factors: interest in food activities and tasting local flavors. Additionally, destination familiarity and preference for destination travel activities are the measures used in the research model. The research sample consists of domestic and foreign tourists visiting Gaziantep between March and April 2022; 418 questionnaires were filled in by participants chosen by random sampling. Data analysis was made using SPSS and SmartPLS. As reflective and formative scales were used together in the data analysis, the partial least squares method (PLS-SEM) was used. The research results suggest that preference for proximity and comfort, interest in new and local culture, preference for activities and adventures, and destination familiarity have a positive significant effect on interest in food activities. While interest in the new and local culture and preference for activities and adventures, have a positive significant effect on tasting local flavors; preference for proximity and comfort and destination familiarity do not have such an effect. It was also found that preference for proximity and comfort, interest in the new and local culture, preference for activities and adventures, and destination familiarity have a positive and significant effect on preferences for destination travel activities. Lastly, interest in new and local culture and preference for activities and adventures have a positive significant effect on destination familiarity while preference for proximity and comfort do not
