    The aim of this study is to reveal the factors affecting Industry 4.0 technology acceptance within the framework of a newly proposed Technology Acceptance Model (TAM) of medium and large-scale firms in Manisa and Izmir Organized Industrial Zones, which are important industrial centres in Turkey. Within the scope of the study, managers of 204 firms operating in Manisa and Izmir Organized Industrial Zones have been interviewed and the data obtained has been analysed by Structural Equation Modelling (SEM) within the scope of TAM. According to the findings, it has been found that perceived usability, perceived ease of use, perceived self-efficacy and financing factors affect attitude towards Industry 4.0 use. In addition, it has been concluded that the attitude towards the use of Industry 4.0 also affects the Industry 4.0 usage intention and the Industry 4.0 usage intention affects the usage behavior

    The antifungal properties of some commercial plant waters obtained as side products in producing distilled oils were investigated. Paper disc samples were impregnated with various plant waters and exposed to wood decay fungi for 3 months in Petri dishes. Ten types of plant water (Laurus nobilis, Calluna vulgaris, Lavandula stoechas, Thymus vulgaris, Myrtus communis, Eucalyptus globulus, Mentha pulegium, Urtica dioica, Melissa officinalis, and Matricaria chamomilla were examined. Seven fungi were used (Phanerochaete chrysosporium, Ceriporiopsis subvermisphora, Gloeophyllum trabeum, Trametes versicolor, Oligoporus placenta, Pleurotus ostreatus, and Coniophora puteana). The antifungal activities of the plant waters obtained from thyme and lavender were particularly high

    Investigating the association between ınternet addiction, depression, social phobia, social anxiety and psychiatric disorders among secondary education students in Turkey

    Introduction: The purpose of the study is to identify the prevalence of Internet addiction (IA) among students and evaluate the association of IA with depression, social phobia, social anxiety and psychiatric disorders. Materials and Methods: A total of 297 students aged 9-14 years and studying at a private school in Gölbaşı/Ankara province were included in the study. The study was conducted between November 2015 and May 2016. The student’s depression inventory; social phobia scale for student and adolescents; social anxiety scale for student-revised and strength and difficulties questionnaire were used as data collection tools. According to the Internet dependency scale, student were classified into 4 groups as non-addicted group, threshold group, risk group and addicted group. Results: According to the Internet dependency scale, the majority (258/86.9%) of the students were not Internet addicts. Twenty seven (9.1%) students were in the threshold group and 12 (4%) student were in the risk group. Compared with the depressed mood, the likelihood of having depression in the risk group was higher (p=0.001). The risk group and the threshold group had higher social phobia and social anxiety scores at a statistically significant level than the non-dependent group (p?0.05). Conclusion: Internet use is an indispensable element for the lives of generation-Z student. However Internet addiction, which is directly related to this condition, causes many psychological and social problems for student at an alarming level. These problems cannot be ignored and can be avoided by rational use of the internet. © 2022, Galenos Publishing House.

    This study investigates the larvicidal activities of plant extracts and tannins against wood-damaging insects. Scots pine (Pinus sylvestris), beech (Fagus orientalis), and poplar wood (Populus tremula) were subjected to larvae of Spondylis buprestoides (Coleoptera: Cerambycidae) by impregnating them with mimosa (Acacia mollissima), quebracho (Schinopsis lorentzii) and redpine bark (Pinus brutia) extracts. At the end of the 6-month experiment, the numbers of dead and live larvae as well as the mean mass losses of woods were determined. In terms of wood species, the lowest larva resistance was observed in Scots pine wood, while the highest larva resistance was achieved by beech wood. The lowest mass losses and the highest dead termite rates in all tree species were observed when the concentration of mimosa and quebracho extracts was 12%. On the other hand, the pine bark extract showed a lower larvicide effect than the other two extracts

    Konjenital ekstremite anomalilerinin intrauterin dönemde ultrasonografi ile erken tespiti gerekli danışmanlığın verilebilmesi açısın- dan önemlidir. Bu makalede sporadik fokomeli olduğu düşünülen postmortem muayene sonuçlarıyla da bu tanı ile uyumlu olduğu görülen bir olgunun sunulması amaçlanmıştır. 20 yaşında, primigravid, kendisinin ve eşinin soygeçmişinde bilinen konjenital ano- mali öyküsü saptanmayan olgunun 22. gebelik haftasındaki obstetrik ultrasonografisinde fetal ekstremite anomalileri izlendi. Tanıyı doğrulayan postmortem radyolojik ve genetik incelemeler yapıldı. Eşlik eden ek malformasyon saptanmadı. Düşük materyalinden yapılan kromozom analizinde herhangi bir sayısal veya gross yapısal kromozom anomalisi gözlenmedi. Patolojik ultrasonografik ve sitogenetik bulgular ile tanı konulan iskelet anomalilerinin postnatal olarak da doğrulanması ailelere verilecek genetik danışma ve olası diğer gebelikler için uygun izlem olanakları sağlayacaktı

    Real-world efficacy and safety of Ledipasvir plus Sofosbuvir and Ombitasvir/Paritaprevir/Ritonavir +/- Dasabuvir combination therapies for chronic hepatitis C: A Turkish experience

    Background/Aims: This study aimed to evaluate the real-life efficacy and tolerability of direct-acting antiviral treatments for patients with chronic hepatitis C (CHC) with/without cirrhosis in the Turkish population.Material and Methods: A total of 4,352 patients with CHC from 36 different institutions in Turkey were enrolled. They received ledipasvir (LDV) and sofosbuvir (SOF)+/- ribavirin (RBV) ombitasvir/paritaprevir/ritonavir +/- dasabuvir (PrOD)+/- RBV for 12 or 24 weeks. Sustained virologic response (SVR) rates, factors affecting SVR, safety profile, and hepatocellular cancer (HCC) occurrence were analyzed.Results: SVR12 was achieved in 92.8% of the patients (4,040/4,352) according to intention-to-treat and in 98.3% of the patients (4,040/4,108) according to per-protocol analysis. The SVR12 rates were similar between the treatment regimens (97.2%-100%) and genotypes (95.6%-100%). Patients achieving SVR showed a significant decrease in the mean serum alanine transaminase (ALT) levels (50.90 +/- 54.60 U/L to 17.00 +/- 14.50 U/L) and model for end-stage liver disease (MELD) scores (7.51 +/- 4.54 to 7.32 +/- 3.40) (p<0.05). Of the patients, 2 were diagnosed with HCC during the treatment and 14 were diagnosed with HCC 37.0 +/- 16.0 weeks post-treatment. Higher initial MELD score (odds ratio [OR]: 1.92, 95% confidence interval [CI]: 1.22-2.38; p=0.023]), higher hepatitis C virus (HCV) RNA levels (OR: 1.44, 95% CI: 1.31-2.28; p=0.038), and higher serum ALT levels (OR: 1.38, 95% CI: 1.21-1.83; p=0.042) were associated with poor SVR12. The most common adverse events were fatigue (12.6%), pruritis (7.3%), increased serum ALT (4.7%) and bilirubin (3.8%) levels, and anemia (3.1%).Conclusion: LDV/SOF or PrOD +/- RBV were effective and tolerable treatments for patients with CHC and with or without advanced liver disease before and after liver transplantation. Although HCV eradication improves the liver function, there is a risk of developing HCC.Turkish Association for the Study of The Liver (TASL

    WOS: 000291232900010In this study, utilizing the wastes of valonia oak (Quercus ithaburensis Decne subsp macrolepis) in P ostreatus cultivation is investigated. The tannin obtained from Valonia oak mostly utilized in leather industry. After having been extracted for tannin, the waste has no industrial utilization yet in Turkey. Milled valonia oak wastes composed of acorn cup held high humidity; therefore, has high drying cost for transporting as well as storage problems of the mills. Valonia oak wastes were used as compost to cultivate P streams. Results indicated that the mycelia development on oak wastes were realized 45 days yield of 24.5% (weight/weight) which is to be considered as potential substrate for P ostreatus cultivation
