Análisis de la relación entre el uso del teléfono y la adicción a teléfonos inteligentes basada en ciertas variables

Purpose: The purpose of the study is to investigate the relationship between technology usage and Smartphone addiction according to certain variables. Method: In this study, which was conducted with the purpose of determining the opinions of preservice teachers, a scanning model was employed. The sample of the study consists of 714 preservice teachers who studied at the Atatürk Education Faculty of Near East University, who were selected based on a random sampling method. In the study, a demographic information form prepared by the researchers was used in order to obtain the required data. The preservice teachers who participated in the study voluntarily were asked to provide information on their demographic features such as age and gender, period of using social networking sites, daily usage habits of smartphones, daily average time spent on social networking sites, average time spent using technological devices and their reasons for using smartphones. The Smartphone Addiction Scale Short Form adapted to the Turkish language by Noyan, Darcin, Nurmedov, Yılmaz and Dilbaz, (2015)and the Opinion Scale for Technological Device Usage developed by Arnavut and Bicen, (2013)  were both used. Findings: The conducted multiple regression analysis showed that the role of technology in life, communication and the usage of social media were significant predictor of smartphone addiction (F (3.709) = 282.065, p<.001). According to the obtained results, it was seen that the total variance explained 54% (R=.74, R2=.54, p<.001).A significant difference was observed in the communication dimension according to the age variable of the research (p=0.02), whereas no significant difference was found between smartphone addiction, social media usage and the role of technology in life (p<0.05). Tukey test analysis showed that the communication score increased with age. Conclusion: According to the obtained conclusions, it was found out that males predominantly use smartphones for communication purposes. No significant difference was found in terms of smartphone addiction. A high and significant relationship was found in a positive direction between smartphone addiction and social media usage. Additionally, a medium and significant relationship in a positive direction was found between smartphone addiction and the role of technology in life. Objetivo: El objetivo del estudio es investigar la relación entre el uso de la tecnología y la adicción a teléfonos inteligentes de acuerdo con ciertas variables. Método: En este estudio, que se realizó con el propósito de determinar las opiniones de los profesores en prácticas, se empleó un modelo de escaneo. La muestra del estudio consta de 714 maestros en prácticas que estudiaron en la Facultad de Educación de Atatürk de la Universidad del Cercano Oriente, que fueron seleccionados en base a un método de muestreo aleatorio. En el estudio, se utilizó un formulario de información demográfica preparado por los investigadores para obtener los datos requeridos. Se solicitó voluntariamente a los maestros en prácticas que participaron en el estudio que proporcionaran información sobre sus características demográficas, como edad y sexo, período de uso de redes sociales, hábitos de uso diario de teléfonos inteligentes, tiempo promedio diario en redes sociales, tiempo promedio de uso dispositivos tecnológicos y sus razones para usar teléfonos inteligentes. Se utilizaron la forma abreviada de la Escala de Adicción al Teléfono Inteligente adaptada al idioma turco por Noyan, Darcin, Nurmedov, Yılmaz y Dilbaz, (2015) y la Escala de Opinión para el uso de Dispositivos Tecnológicos desarrollada por Arnavut y Bicen (2013). Hallazgos: El análisis de regresión múltiple realizado mostró que el papel de la tecnología en la vida, la comunicación y el uso de las redes sociales fueron un importante predictor de la adicción a los teléfonos inteligentes (F(3.709) = 282.065, p < .001). De acuerdo con los resultados obtenidos, se observó que la varianza total explicaba 54% (R = .74, R2 = .54, p < .001). Se observó una diferencia significativa en la dimensión de comunicación según la variable de edad de la investigación (p = .02), mientras que no se encontraron diferencias significativas entre la adicción a los teléfonos inteligentes, el uso de las redes sociales y el rol de la tecnología en la vida (p < .05). El análisis de prueba de Tukey mostró que la puntuación de comunicación aumentó con la edad. Conclusión: De acuerdo con las conclusiones obtenidas, se descubrió que los hombres usan predominantemente teléfonos inteligentes con fines de comunicación. No se encontraron diferencias significativas en términos de adicción a teléfonos inteligentes. Se encontró una relación alta y significativa en una dirección positiva entre la adicción a los teléfonos inteligentes y el uso de las redes sociales. Además, se encontró una relación media y significativa de manera positiva entre la adicción a los teléfonos inteligentes y el papel de la tecnología en la vida

Influence of water stress prior to harvest on yield and essential oil content of pot grown lemon balm

Lemon balm (Melissa officinalis L.) is a perennial herbaceous plant widely used in modern and traditional medicine. The aboveground part, particularly the leaves, has many benefits; in traditional medicine, it is used for the preparation of various teas and tea blends, while in modern medicine to obtain essential oil as it is considered a precious product. Nowadays, the needs for lemon balm are mostly met by growing it in the open field. The quality of its leaves as well as the content of its essential oil mostly depend on the way the plant is grown. In stress conditions, medicinal plants use to increase the content of their secondary metabolites. Therefore, this study aimed to determine whether water deficit has an impact on the content of essential oil in lemon balm grown as a pot culture. The experiment was conceived in such a way that at the beginning of the flowering phase, cultivated plants were given different treatments. Treatment A represented plants that were not subjected to water stress, while in treatments B and C, prior to harvesting the plants have been subjected to water stress for 7 and 14 days, respectively. By the end of the experiment, the morphological parameters per plant were measured and the contents of essential oil per treatment determined, all in triplicates. The obtained results indicate that water stress had a great impact on the yield of the aboveground biomass of lemon balm plants as well as on the content of essential oil in their leaves. The highest average yield of the aboveground biomass was obtained in treatment A (1204.0 g) while the highest average yield of the essential oil in treatment C (0.59 g). In short, an increase in water stress increased its positive effects on lemon balm grown as pot culture
