Authors: Arslan Ayşe , Tanrısevdi Abdullah
Published: June 2022

Turizm sektörünün en önemli işgörenleri arasında yer alan turist rehberleri (TR) turist memnuniyetinde oldukça önemli bir role sahiptir. Yabancı literatürde TR’lerin performans kriterleri ve turist memnuniyetine olan etkisi birçok çalışmaya konu olurken; Türkçe literatürde sınırlı sayıda çalışmaya rastlanmıştır. Özellikle Efes Antik Kenti gibi her yıl milyonlarca turist tarafından ziyaret edilen yerlerde verilen rehberlik hizmetinin değerlendirilmesi sürekli değişen pazar beklentilerinin karşılanabilmesi için bir gerekliliktir. Bu kapsam doğrultusunda çalışmanın amacı, TR’lerin performansının turistlerin memnuniyetine olan etkisini ortaya koymaktır. Araştırmada nicel araştırma yöntemlerinden anket tekniği kullanılmıştır. Araştırmanın evrenini Efes’i Temmuz-Eylül 2021 arasında ziyaret eden yerli turistler oluşturmaktadır. Örneklem olarak olasılıklı olmayan örnekleme yöntemlerinden kolay örnekleme yöntemi tercih edilmiştir ve toplam 399 veri toplanmıştır. Elde edilen veri, en küçük kareler yöntemi ve yapısal eşitlik modellemesi ile analiz edilmiştir. Analiz sonucuna göre TR’lerin eğlence tanıtma becerisi, görünüşü, problem çözme becerisi ve örgütsel becerisi, yerli turistlerin memnuniyetini anlamlı ve olumlu yönde etkilemektedir. TR’lerin empati becerisi, mesleki yeterliliği ve iletişim becerileri yerli turist beklentilerinin altında kalmıştır.

Authors: Yaman Songur Demet
Published: June 2022

Ekonomide belirsizlik, dış ticaret ve döviz kuru gibi makro ekonomik değişkenler üzerinde etkili olabilmektedir. Küreselleşmenin ilerlemesi ve ekonomilerin karşılıklı bağımlılığının artmasıyla birlikte uluslararası ticaret, ekonomide yaşanan belirsizlik ortamından güçlü bir şekilde etkilenmektedir. Literatürde ekonomi politika belirsizliğinin dış ticaret üzerindeki etkilerine ilişkin tam olarak bir görüş birliği bulunmamakla birlikte, yapılan çalışmalar sonucunda ortaya çıkan genel görüş, belirsizliğin ticaret akımlarını baskıladığı yönündedir.
Bu çalışmanın amacı ekonomi politika belirsizliğinin 18 ülkenin ithalatı üzerindeki etkisini, 1997-2019 dönemine ait yıllık veriler kullanılarak panel veri teknikleri ile analiz etmektir. Analizde ele alınan ülke grubu verilere erişim sıkıntısı olmaması göz önünde bulundurularak seçilmiştir. Elde edilen sonuçlar incelenen dönemde ele alınan tüm ülkelerde ekonomi politika belirsizliğinin ithalatı negatif yönde etkilediğini göstermektedir.

Quality of higher education in Russia: cognitive resources of online-learning
Authors: Kovalev Vitaly , Dyatlov Alexander , Latsveeva Alexandra
Published: June 2022

This article is devoted to the analysis of online training resources for quality assurance in higher education in Russia. The review of the scientific literature has led to the conclusion that in the Russian scientific discourse the potential of online learning to ensure the expected quality of higher education through resource potential has been practically not studied. The aim of the study: to determine the sufficiency of online learning resources to ensure the expected quality of education in the social institution of higher education in Russia. The methodological basis is the neo-institutional approach. Prior to the empirical study, the following basic concepts were operationalized: quality of higher education, institution of higher education, online learning, resources of quality of higher education. The result of the operationalization was the definition of two empirical indicators: 1)students' resources for quality education in an online learning environment; and 2)faculty resources for quality education in an online learning environment. The study found that the vast majority of teachers indicated a dramatic decrease in the effectiveness of their educational activities when they went online. This includes a decrease in professional motivation and interest in the end result of work, mental detachment from and indifference to learners, increased anxiety due to fears of health deterioration, indifference to professional development, loss of visual and non-verbal control over students, etc. The teachers' opinion on the main positions correlates with the students' point of view. However, among the students a stable group of about 25% was identified, which is focused on online learning and demonstrates the belief that under its implementation their resources for quality education increase. We formulated a proposal according to which this group of students should be trained in special online (digital) schools on a reduced program, where the priority will be accelerated vocational training.

Published: June 2022

Cerebral venous sinus thrombosis (CVT) is a rare cause of stroke, a life-threatening disorder that occurs in approximately 0,5-1% of all stroke incidents. Various clinical presentations, risk factors, and neuroimaging findings of this disease may cause a delay in the early diagnosis and treatment of CVT. We discuss a case of a 34-year-old female who was admitted to the emergency room (ER) with the onset of a generalized tonic-clonic seizure with a progressive headache in the occipitotemporal region. Based on head CT, there was multiple hyperdense and cerebral venous infarction in the posterior left parietal lobe. D-dimer evaluation, there was an increasing level of D-dimer (>10.000 ng/mL). The patient was treated with the primary therapy heparin. After 15 days of being hospitalized, the patient was discharged without any sequelae.

Authors: Parmasari Wahyuni Dyah , Hakim Nauval , Soekanto Ayly
Published: June 2022

Anxiety is assumed to be an unclear feeling, which causes worry, fear of everything that does not necessarily happen. This anxiety has a psychological impact on a person including it can affect learning achievement. Various studies related to anxiety theory state that gender affects the level of anxiety. Women are considered more prone to anxiety than men. In this study, researchers measured men's anxiety degrees compared to women when taking computer-based tests (CBT) during the pandemic. Exams with this method are suspected to be one of the triggers for anxiety in medical students. The purpose of this study was to compare the level of anxiety of students and female students in facing CBT at Wijaya Kusuma University Surabaya during the pandemic. This study used a cross-sectional approach with a total sampling technique. The total number of respondents was 60 people, 16 men and 44 women. Respondents' anxiety degrees were measured by a measurement scale of depression, anxiety, and stress or what is known as the Depression Anxiety and Stress Scale 21 (DASS-21). The results showed that 12.5% of men and 31.8% of women were in the heavy and very heavy group. The conclusion of this study is that the level of anxiety of women is higher than those men.

Introducción: Las lenguas indígenas son utilizadas por instancias públicas en comunicaciones sobre la emergencia COVID-19 aunque los materiales disponibles aún son limitados, y en ocasiones no son accesibles. Objetivo: Generar comunicaciones en salud acordes a la realidad del grupo indígena más numeroso de México: el pueblo maya. Metodología: Se conformó un equipo multidisciplinario de trabajo, se realizó una búsqueda de materiales oficiales y un sondeo en comunidades mayas, para identificar las necesidades de información. Se realizó la adecuación lingüística y considerando las condiciones socioculturales. Resultados: Los productos se realizaron con audio en maya, pues la mayoría de los mayahablantes no lee en su lengua. Se elaboraron tres videos y un programa de seis episodios de podcasts en formato digital y de radio tradicional. Incluyen información general de salud y temáticas que han tenido limitada cobertura en lengua maya. Conclusión: Con las comunicaciones generadas, se espera contribuir a una mayor equidad en la información en el marco de COVID-19 y a visibilizar la importancia de la lengua maya para los mensajes de salud.
Comunicación diaria de cifras corregidas de mortalidad en España durante la segunda ola de la pandemia COVID-19
Authors: Equiza-Goñi Juan
Published: June 2022

Introducción: MoMo monitoriza y comunica diariamente la mortalidad en España, pero el retraso en la notificación de defunciones sesga a la baja sus estimaciones. Objetivo: este estudio evaluó cinco métodos que corrigen el efecto del retraso en la notificación en las estimaciones de MoMo del exceso de mortalidad durante la segunda ola de la epidemia COVID-19. Metodología: 1) se obtuvieron las cifras de exceso de muertes acumuladas en España comunicadas diariamente por MoMo entre 01/09/2020-25/12/2020. 2) se corrigió en dichas cifras el efecto del retraso en la notificación aplicando cinco modelos. 3) se evaluaron estas correcciones mediante el error absoluto medio (MAE) y la raíz del error cuadrático medio (RMSE). Resultados: el retraso en la notificación supuso que las estimaciones de MoMo para el exceso de mortalidad acumulado durante la segunda ola fueran, de media, un 87% de sus valores definitivos. Las correcciones cuadráticas y cúbicas las acercaron hasta el 98%, de media. Las regresiones cuadráticas redujeron el RMSE y el MAE de las estimaciones de MoMo en un 6 y 13%, respectivamente. Conclusión: para mejorar las estimaciones diarias de MoMo del exceso de mortalidad parece recomendable usar regresiones cuadráticas para corregir los efectos del retraso en la notificación de defunciones.

Este estudio está dirigido a estudiantes adolescentes, etapa donde se observa un aumento de la discriminación y el prejuicio. El respeto a las ideas de los demás y la necesidad de hacer un ejercicio de comprensión para entender las circunstancias de cada persona es algo fundamental para erradicar prejuicios raciales. En la actual sociedad del miedo y la incertidumbre, el racismo involucra a todas las personas y se acrecienta con una mayor facilidad.
Automatismo ontem e hoje
Authors: Gonçalves Rafael
Published: June 2022

Com a crescente popularidade das técnicas de inteligência artificial, questões relativas às capacidades e limitações dessas tecnologias ganham notoriedade. Este trabalho propõe que, como formas contemporâneas de automatismo, tais tecnologias compartilham semelhanças com as analisadas pela filosofia da técnica de Gilbert Simondon e que, por isso, seu pensamento seria de grande valor para refletir sobre elas. Partindo principalmente da “Nota complementar sobre as consequências da noção de individuação”, e tomando o algoritmo rede neural artificial como exemplo, o artigo apresenta três momentos em que a inteligência artificial apresentaria limitações em relação a sua estrutura fixada pelo humano inventor: nos dados de entrada, no treinamento do modelo e na representação final do conhecimento supostamente aprendido. O artigo conclui com uma breve análise das consequências do uso extensivo de tecnologias inteligentes à luz das limitações apresentadas.

A layered lithium nickel manganese oxide as environmentally friendly cathode material for secondary batteries
Authors: Arinawati Meidiana , Nugroho Firmansyah Adi , Yudha Cornelius Satria
Published: June 2022

Cobalt-free cathode material development is considered necessity to assure the sustainability of Li-ion batteries. Cobalt is always considered expensive and unsafe for both human and environment. LiNi0.5Mn0.5O2 (LNMO) is a layer structured cathode material that has similar feature to LiCoO2 (LCO). A simple and fast processing of LNMO is proposed. A precipitation of nickel manganese oxalate was obtained in a batch reactor under atmospheric condition. The as-obtained homogenous oxalate precursor was converted to LNMO via high temperature lithiation. Based on the XRD result, a crystalline product with layer structure is successfully obtained. The presence of impurities such as residual Li can be detected from the FTIR spectra. SEM Images confirmed quasi-spherical particles with grain size of less than 10 micrometer. The charge-discharge analysis of LNMO containing cell deliver a capacity of 42 mAh/g. In spite of its promising report, continuous improvement is necessary to obtain cell with better electrochemical performance.

Published: June 2022

El objetivo de esta investigación fue comparar la acción solvente del óleo de naranja, eucaliptol y óleo experimental de hierba luisa sobre conos de gutapercha para técnica en frío y técnica termoplastificada. Metodología: La muestra estuvo compuesta por 80 conos de gutapercha n.o 80 Endomedic y F3 ProTaper Universal. Los conos se dividieron en 4 grupos (n = 20) según el tipo de solvente y, a la vez, cada uno se dividió en dos subgrupos (n = 10) según el tiempo de exposición (5 min y 10 min). Los conos se sumergieron en el solvente respectivo durante 5 o 10 minutos. Luego, se lavaron con 5 ml de alcohol durante 5 minutos y se enjuagaron con agua. Finalmente, luego de secar a temperatura ambiente por una hora, la acción solvente se registró en gramos (g) de pérdida de peso. Los resultados fueron analizados y comparados mediante la prueba de Tukey (p < 0,05). Resultados: El cono Endomedic expuesto durante 5 min a eucaliptol obtuvo el promedio de peso más bajo (0,0625 ± 0,0009 g), seguido del óleo de hierba luisa (0,0629 ± 0,0003 g) y óleo de naranja (0,0629 ± 0,0010 g), aunque no se encontró diferencia significativa (p > 0,05) entre cada uno. Conclusión: El solvente experimental de hierba luisa, el eucaliptol y el óleo de naranja presentaron un efecto solvente similar sobre los conos de gutarpercha para técnica en frío y termoplastificada. A nivel clínico los tres solventes estudiados podrían usarse en el retratamiento endodóntico como soluciones alternativas de similar efecto solvente.

The effects of a three-day mountain bike cycling race on the autonomic nervous system (ANS) and heart rate variability in amateur cyclists: a prospective quantitative research design
Authors: Swart Anton
Published: June 2022

Background
Increased endurance exercise may cause an acute reduction in cardiac function, causing a physiological cascade. Heart rate variability (HRV) is a physiological measurement used to evaluate the autonomic nervous system (ANS) state. This study set out to determine the changes in the ANS by participating in a three-day mountain bike cycling event using HRV as an outcome measure.
Methods
Sixteen healthy participants (male and female) participating in a three-day mountain bike cycling event underwent five-minute resting electrocardiography (ECG) recordings in a supine position. In addition, heart rate variability measurements were recorded two days before the race (baseline testing), after each race day, and 24-hours post-event (recovery).
Results
Time-domain and frequency domain measures showed significant changes from baseline HRV parameters after each race day (p ≤ 0.05). In addition, our data revealed that the mean heart rate (HR) and R-R variability intervals did not return to baseline values after 24-hours of recovery. Thus, reflecting autonomic nervous system (ANS) dysfunction due to increased sympathetic activity and parasympathetic withdrawal.
Conclusions
The main strength of this study is using HRV as a measuring and screening tool to assess cardiac autonomic activity, whereby the state of the ANS before and after endurance events can be measured. Thus, physicians, athletes, and coaches can assess the stress of endurance events on the ANS and plan for correct recovery strategies. The reasoning is that if the ANS is in a state of dysfunction, susceptible amateur athletes might be at risk for a cardiovascular event.

The gut microbiota has recently been postulated to be involved in MDD through gut-brain axis signaling. Moreover, antidepressants contain antibacterial properties in the gastrointestinal tract. The aim of this study was to compare the gut microbiota and inflammatory profile of patients with MDD before and after initiation of pharmacological and/or cognitive antidepressant treatment in comparison with non-depressed individuals (nonMDD).
Methods
Study participants delivered fecal and blood samples at baseline and at follow-up after four and twelve weeks, respectively. Patients started treatment immediately after the delivery of the baseline samples. The gut microbiota was characterized by 16S rRNA gene sequencing targeting the hypervariable V4 region. Inflammation was assessed based on plasma levels of 54 immune markers using Meso Scale.
Results
In total, 27 patients and 32 nonMDD controls were included in the study. The gut microbiota in the baseline samples of MDD versus nonMDD participants did not differ regarding α- or β-diversity. However, there was a higher relative abundance of the genera Ruminococcus and Intestinibacter and a lower relative abundance of the genera Lactobacillus, Bilophila, Coprobacter, and Desulfovibrio in the MDD group compared to the nonMDD group. In the MDD group, the families Ruminococcaceae, Clostridiaceae and Peptostreptococcaceae were found depleted after twelve weeks follow-up compared to the baseline samples. In the MDD group, IL-7, IL-8 and IL-17b were elevated compared to the nonMDD group.
Conclusion
Intestinal bacteria Ruminococcus, Coprobacter and Lactobacillus were significantly different between antidepressant-naïve patients with MDD and nonMDD controls. Genera belonging to Ruminococcaceae also changed in relative abundance in patients with MDD during pharmacological and/or cognitive antidepressant treatment. The MDD group was found to have a pro-inflammatory profile compared to the nonMDD group.

The deformation prediction of the chamber roof is crucial in underground mining. Combined with Flac3D numerical simulation, the experimental design methodologies, including single-factor test (SFT), Plackett-Burman design (PBD), steepest ascent design (SAD), and response surface methodology (RSM), were used to evaluate the effect of multiple variables on the chamber roof deformation. Firstly, eight factors that affected the vertical displacement (Ds) of the chamber roof were selected, and the sensitive interval of every factor was obtained through SFT. Then, four factors that significantly affect the results were screened by PBD: cohesion (Co), stope length (Ls), stope width (Ws), and internal friction angle (fr). 29 groups of response surface schemes with 4 factors and 3 levels satisfying the Box-Behnken design (BBD) were simulated. Through the result analysis of variance (ANOVA) and sensitivity, the influence order of each factor on Ds can be determined: Ws >Ls >fr > Co>interaction between Co and fr > interaction between Ls and Ws. Finally, using the prediction model, the roof deformation of 0#N stope of a lead-zinc mine was predicted and the error was analyzed. The relative errors between the prediction value and the numerical simulation value, the measured value are 0.7% and 4.3%, respectively, which indicates that the prediction model is reasonable and has a certain reference value for mine safety.
A new algorithm of distance protection based on the change in phase angle of the voltage
Authors: Ostojić Mladen M. , Stojanović Zoran N
Published: June 2022

The paper presents a new algorithm of distance protection based on the change in phase angle of the voltage. As input signals, the algorithm uses measured voltages at the beginning of the line and auxiliary voltages. Auxiliary voltages were calculated using measured currents and voltages at the beginning of the line and known line parameters. The algorithm compares the instantaneous values of the measured and calculated auxiliary voltages and, based on the change in the phase angle of the voltage, detects a fault on the line. The testing of the presented algorithm was performed with signals obtained by computer simulations of line faults and recordings of faults taken from protective devices from the real network. The obtained results showed good performance of the presented algorithm.
Constructing and validating a Job Strain Index based on five nationwide Norway Surveys of Living Conditions in the Work Environment

Published: June 2022

Background: It has been claimed that Nordic register data are a “goldmine” for research. However, one limitation is the lack of information on working conditions. Job exposure matrices (JEMs) are one solution to this problem. Thus, the twin aim of this study was (i) to investigate the reliability of an occupation-based psychosocial JEM, i.e., a composite Job Strain Index (job strain or JSI abbreviated), and (ii) to examine the construct and criterion-related validity of this measure of job strain. Method: The study utilized five waves of the nationwide Norway Survey of Living Conditions in the Work Environment with a total sample of 43,977 individuals and register data with a total sample of 1,589,535 individuals. Job strain was composed of items belonging to the two dimensions of Karasek’s DC model, job demands and job control (1979). The reliability of the JSI and its dimensions and components were investigated by measuring the degree of agreement (Cohen’s kappa), sensitivity, specificity, and internal consistency (Cronbach’s alpha). Construct validity was assessed by confirmatory factor analysis, and criterion-related validity was measured by concurrent validity and predictive validity. The selected concurrent criteria were self-reported survey information on long-term sick absence, anxiety, depression, and sleeping difficulty. The predictive criteria were register information on receipt of disability benefits, mortality, and long-term sick leave. Results: Agreement between individual and occupation-based job strain and components was fair to poor. The sensitivity and specificity of occupation-based job strain and its components varied from acceptable to low. The consistency of the items comprising job demand and job control was clearly acceptable. Regarding concurrent validity, significant associations between (both individual and occupational) job strain, and long-term sick leave and sleeping difficulty were observed for both genders. Occupation-based job strain indicated an elevated risk for anxiety and depression among men, but not among women. As for predictive reliability, significant associations between occupation-based job strain and all three health outcomes were observed for both men and women. Conclusion: Our occupation-based JSI serves as a reliable and valid indicator of psychosocial job exposure that can be used in analyses of Norwegian register data where individual information on such conditions is missing.

Background: Use of long-term tobramycin inhalation solution (TIS) has been shown beneficial in cystic fibrosis (CF) and earlier findings also suggest a benefit in non-CF bronchiectasis. We investigated the efficacy and safety of maintenance TIS once daily (OD) in frequent exacerbating bronchiectasis patients chronically infected by different pathogens sensitive for tobramycin.Objective: The primary outcome was the frequency of exacerbations during the 12-month study period. Secondary outcomes were time to first exacerbation, change in lung function and quality of life (QoL), bacterial analysis and safety.Materials/patients: In this multicenter RCT patients aged ≥ 18-year-old were included with confirmed bronchiectasis and ≥ 2 exacerbations in the preceding year. Patients were assigned (1:1) to receive TIS or placebo OD for 1-year.Results: 58 patients were included of which 52 were analyzed in the mITT analysis. TIS reduced exacerbation frequency with a RR of 0.74 (0.49-1.14) (p=0.15). Within the TIS population a significant decrease in number of exacerbations was found (2; p=0.00), which was also seen in the placebo-treated patients (1.5; p=0.00). In the TIS-treated patients the QoL significantly improved (LRTI-VAS p=0.02 Leicester Cough p=0.02) without additional safety concerns. No significant differences were found for the other secondary outcomes.Conclusion: Although the predefined 50% reduction in number of exacerbations was not observed, long-term TIS OD is a safe and effective treatment modality in patients with bronchiectasis chronically infected by tobramycin sensitive pathogens. This could be a useful strategy in selected patients with bronchiectasis suffering from a high burden of disease.The BATTLE study was registered at Clinical trials.gov number: NCT02657473.

A taxonomy of policy questions: Examining the style of policy inquires
Authors: Osman Magda , Cosstick Nick
Published: June 2022

To help advance exchanges between science and policy, a useful first step is to examine the questions which policy professionals pose to scientists. The style of a question indicates what the asker is motivated to know, and how they might use that knowledge. Therefore, the aggregate pattern of typical policy inquires can help scientists anticipate what types of information policy audiences desire. A dataset (n = 2972) of questions from policy professionals collected over 10 years (2011–2021)––by the Centre for Science and Policy at the University of Cambridge––was classified into one of seven classes. In the main, the most popular questions posed by policy professionals––within the public and private sectors––were those whose answers inform how to achieve specific outcomes––whether directly, or by providing a causal analysis which is instrumental to this process. Moreover, this seems to be a general aspect of the nature of policy professionals’ inquiries, given that it is preserved regardless of the policy issue considered (e.g., Artificial intelligence, Economy, or Health). Thus, maximizing the usefulness of the information that policy professionals receive when engaging with scientists requires informing how to achieve specific outcomes––directly, or by providing a useful causal analysis.

Published: June 2022

Because of the influence of the structural parameters of the pump shaft transmission system on the dynamic and static performance of the plastic centrifugal pump, according to the structural parameters of the centrifugal pump, the three-dimensional model of the impeller and volute chamber was drawn. The composition of radial force and axial force generated when the plastic centrifugal pump works were analyzed. The CFD calculation of the load of the plastic centrifugal pump was carried out. The flow field of the plastic centrifugal pump under ideal working conditions was simulated by ANSYS FLUENT. Combined with the application principle of singular function in mechanics, the mathematical model of the deflection of the pump shaft transmission system was constructed. And the key factors affecting the deflection of the pump shaft were analyzed. Taking the minimum deflection and the maximum critical speed of the first order as the objective function, the constraint conditions were determined by the geometric relationship, and the optimization model of the structural parameters of the pump transmission system was established. The NSGA-II multi-objective optimization method was used to solve the optimal structural parameters of the optimization model, and the optimization design of pump shaft span, cantilever, front and rear bearing clearance was completed. The optimal span cantilever ratio of the rotor model of the single-span cantilever structure was 1:0.75. The ZT-3 rotor test device was used as a platform to verify the effect of span and cantilever ratio on the dynamic performance of the rotor.
