Determination of presenteism levels of health workers: A research on public and private hospitals
No full textBu araştırmanın amacı, kamuda ve özel sağlık kuruluşunda çalışanpersonelin presenteizm düzeylerini belirlemek ve presenteizm düzeylerindeki farklılığı tespit etmektir. Araştırmanın örneklemini oluşturan Amasya ili merkezde bulunan kamu ve özel sağlık kuruluşlarında çalışan 408 kişiye bu amaç doğrultusunda anket uygulanmıştır. Araştırmanın bulgularına SPSS 25.0 programı kullanılarak ulaşılmıştır. Analizler için %95 güven düzeyi kullanılmıştır. Demografik özelliklerin belirlenmesi için frekans ve yüzde analizinden, ölçeklerin güvenilirlik düzeyleri için içsel tutarlılık yönteminden ve Cronbach Alpha güvenilirlik ölçütünden, işte var olamama ve alt boyutları arasındaki ilişkiyi belirlemede pearson korelasyon analizinden faydalanılmıştır. Katılımcıların düzeylerini incelemek için betimsel analizlerden ort.±s.s verilmiştir. Verilerin dağılımın incelenmesi için merkezi eğilim ölçülerinden ortalama ve medyan değeri incelenirken ölçüm araçların basıklık-çarpıklık değerleri incelenmiştir. Demografik özelliklere göre farklılığı incelemek amacıyla bağımsız örneklem t-testi iki gruplu demografik özelliklerde, tek yönlü Anova analizi ise ikiden fazla gruplarla karşılaştırma yapmak için kullanılmıştır. Analiz sonucuna göre, kamu hastanesinde çalışan personelin presenteizm düzeyleri ile özel hastanede çalışanların çalışma durumu arasında anlamlı farklılık tespit edilmiştir. Özel sağlık kuruluşlarında çalışanların presenteizm düzeyleri kamuya ait sağlık kuruluşlarında çalışanlara göre daha yüksektir. Bununla birlikte kamu ve özel sektör sağlık kuruluşlarında çalışan bireylerin büyük çoğunluğu presenteizm yaşamakta, sadece sağlıkla ilgili faktörlerin presenteizme neden olmadığı belirlenmiştir. Bireysel, örgütsel ve çevresel faktörlerin; presenteizm yaşanmasında etkili olduğu saptanmıştır. Presenteizmin kadınlarda, eğitim seviyesi düşük, yaşı yüksek ve hizmet süresi fazla, kronik bir rahatsızlığa sahip kişilerde daha yüksek olduğu ve daha fazla maruz kalındığı tespit edilmiştir.The aim of this research is to find presenteizm levels of the personnel working in public and private health institutions and to identify differences in presenteizm levels. For this aim, a questionnaire was applied to 408 people working in public and private health institutions in Amasya city centre, which constitutes the sample of the research. The findings of the study were collected by using SPSS 25.0 software. For analyses, 95% confidence interval was adopted. Frequency and percentage analysis were employed to reveal demographic characteristics, internal consistency method and Cronbach Alpha reliability criterion were utilised for the reliability levels of the scales, and Pearson correlation analysis was employed to identify the relationship between work absenteizm and its sub-dimensions. Mean ± s.s. was used in descriptive analyses to examine the levels of the participants. In order to examine the distribution of the data, the mean and median values of the measures of central tendency were examined, while the skewness and kurtosis values of the measurement tools were examined. Independent sample t-test was used in two-group demographic characteristics to examine the difference based on demographic characteristics, and one-way ANOVA analysis was used in more than two groups to make comparisons. The results of the analysis showed that there was a significant difference between the presenteizm levels of the employees working in public hospitals and those working in private hospitals. The presenteizm levels of employees working in private health institutions were higher than those working in public health institutions. On the other hand, it was also found that the majority of individuals working in public and private sector health care organisations experience presenteizm, and not only health-related factors cause presenteizm. Individual, organisational and environmental factors were found to be effective in experiencing presenteizm. It was also found that presenteizm was higher in women, people with lower education level, higher age, longer service period and chronic illnesses and they were exposed to it more

The effects of UGT1A4 and ABCB1 polymorphisms on clozapine and Ndesmethyl clozapine plasma levels in Turkish schizophrenia patients
No full textClozapine (CLZ) is an antipsychotic which is particularly used in treatment resistant schizophrenia patients who do not respond to other agents. It is preferred because it reduces suicidal behaviours and attempts, reducing aggression and violent behaviour. The aim of the study is to evaluate the effects of ABCB1 rs1045642 and UGT1A4 rs2011425 polymorphisms on CLZ and its major metabolite Ndesmethly clozapine (DCLZ) plasma concentrations in patients with schizophrenia. A total 109 of Turkish patients with schizophrenia on continually administered CLZ monotherapy were included. The plasma concentrations of CLZ and DCLZ were measured using an HPLC after liquid-liquid extraction while, transporter gene ABCB1 and phase two enzyme UGT1A4 polymorphisms were identified using PCR- RFLP method. Results showed that UGT1A4*3 polymorphism has statistically significant effects on CLZ C/D and DCLZ C/D levels in patients with sub/supra therapeutic levels while ABCB1 C3435T polymorphism has a significant effect on CLZ/DCLZ ratio among patients who have subtherapeutic levels. This study indicates the influence of genetic differences on plasma levels and highlights the importance of pharmacogenetic studies in clinic. Using the obtained results as pharmacogenetic biomarkers will help clinicians provide effective treatment in individual patients and reduce the undesirable side effects.Ankara University Scientific Projects Coordination Unit [18 L0217001]This study was supported by a Grant from the Ankara University Scientific Projects Coordination Unit [18 L0217001]

Utilizing quantitative data, the study adopted a quasi-experimental pre-test–post-test control group design. The study group consisted of 31 children receiving preschool education at a kindergarten affiliated with the Ministry of National Education in the central district of Sivas during the 2021–2022 academic year. Of these, 16 were assigned to the experimental group and 15 to the control group. Data were collected using the Children's Information Form and the Phonological Awareness Skills Assessment Subtest of the Early Literacy Skills Assessment Tool. For data analysis, both Independent Samples t-Test and Paired Samples t-Test were employed, and effect size was calculated using Cohen’s d. The pre-test results indicated that the phonological awareness skills of the experimental and control groups were at similar levels prior to the intervention. The post-test results revealed a statistically significant improvement in the phonological awareness skills of the children in the experimental group, who participated in traditional word-based games and rhymes. In contrast, no significant difference was observed in the control group. Furthermore, the difference in scores between the experimental and control groups on the Phonological Awareness Skills Assessment Subtest was found to be of moderate effect size. Retention test results indicated that the positive effect of traditional children’s games and rhymes on the phonological awareness skills of the children in the experimental group persisted over time

Response of inflammatory cytokine levels in calves with LPS-induced endotoxemia
No full textThe most common form of toxemia observed in large animals is endotoxemia. Endotoxemia is caused by the presence of lipopolysaccharide cell wall components of gram-negative bacteria in the blood and characterized clinically by abnormalities of many body systems. This study aimed to determine changes in serum inflammatory cytokine levels in calves with LPS-induced endotoxemia. Ten healthy Holstein breed calves were used in the study. To create experimental endotoxemia, LPS at 0.1 µg/kg dose was given intravenously to the calves from the vena jugularis as an infusion within 30 min. Blood samples to evaluate cytokines, biochemical, blood gases, and hematological parameters were collected before LPS infusion (0. hour) and at 1, 2, 3, 4, 6, 12, 24, and 36 h following LPS infusion. In the first 4 h following the LPS infusion, calves’ body temperature, heart and respiratory rate, and capillary refill time increased, while a decrease was observed in the following hours. Significant changes were detected in blood pH, WBC, and glucose levels after LPS administration. Serum TNF-α, IL-6, IL1-β, IL-10, and IFN-γ levels were low before the LPS infusion in the calves, while increased within the first 4 h following the LPS infusion, however, statistical significance was observed in TNF-α, IL-6, and IFN-γ. Cytokine levels decreased back to baseline levels after the fourth hour. As a result, it was found that 0.1 µg/kg dose of LPS administrated as infusion caused changes in clinical, hematological, blood gases, biochemical parameters, and significant increases in the levels of circulating cytokines. The results of this study showed that the changes observed in the organism during natural endotoxemia can also be revealed experimentally by administering LPS intravenously. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2024.Selcuk University Scientific Research Projects Coordinato

The Impact of Impingement Surface Angle Variation and Channel Design on Heat Transfer Performance and Flow Characteristics for Twin Jet Impingement
No full textThis study intends to give a detailed research of surface angles of impingement, and jet-plate distances to enhance heat transfer and improve the channel's flow structure features for twin jet impingement. For this aim, numerical analysis of twin jet impingement was carried out for distinct impingement surface angles (alpha) of 30 degrees, 45 degrees, and 60 degrees and impinging jet-plate distances (H) of 3, 4.5, and 6. The numerical investigation was performed as a steady, twodimensional, employing the k-epsilon turbulence model and the Ansys-Fluent program in the twin jet rectangular channel. While the isothermal flat plate impingement surface has 310 K (T-H), the impinging air jet fluid temperature is 300 K (T). The obtained outcomes were compared with the numerical and experimental outcomes of the work in the literature and it was noticed that they are determined to be compatible. The results were presented as the local Nu number (Nu(L)) variations for alpha = 30 degrees, 45 degrees and 60 degrees impingement surface angles along the flat plate impingement surface, and the variations of mean Nu numbers (Nu(m)) for different alpha and H values with the Re number ranges of 20000-50000. Besides, streamlines and temperature isotherms were evaluated for different alpha, H and Re number values by visualising them in detail. The results displayed that while the Num values are higher than the case without angle (alpha = 0 degrees) for all angles and H values, after the 30 degrees angle, the Nu(m) values decrease slightly at 45 degrees and 60 degrees. Accordingly, for H = 6, the Num value of 30 degrees impingement surface angle is 3.09% higher than that in 60 degrees
Photocatalysis and adsorption coupling in S-scheme K and P doped g-C3N4/GO/MgFe2O4 photocatalyst for enhanced degradation of Congo red dye
No full textPhotocatalysis is an environmentally friendly approach for harnessing solar light to degrade pollutants. This study investigates the degradation of Congo red (COR) dye by a visible light-active photocatalyst, with a primary focus on the efficiency and reusability of the photocatalytic material. We synthesized phosphorus- and potassium-doped graphitic carbon nitride photocatalysts attached to graphene oxide and MgFe2O4 (KPCN/GO/MgFe2O4). Doping graphitic carbon nitride enhanced light absorption, while graphene oxide improved the adsorption properties. The addition of magnetic MgFe2O4 enhanced charge separation and reusability. The KPCN/GO/MgFe2O4 composite was analyzed using a range of techniques. The activity of the synthesized materials for Congo red (COR) dye degradation was analyzed under visible light. The photocatalytic activities of bare, binary, and ternary photocatalysts were compared, and KPCN/GO/MgFe2O4 exhibited the highest photoactivity among all. The KPCN/GO/MgFe2O4 photocatalyst (60 mg) showed a 76% removal efficiency for 5 x 10-6 M Congo red within 60 min, which was 2.5 times higher than that of pure graphitic carbon nitride. The OH and O2- were the major reactive species during COR photodegradation. The photocatalyst also displayed good reusability after five cycles, enhancing its overall effectiveness.King Abdulaziz University, Jeddah [486-130-1440]; Deanship of Scientific Research (DSR) at King Abdulaziz University, JeddahThis Project was funded by the Deanship of Scientific Research (DSR) at King Abdulaziz University, Jeddah, under grant no.
