Authors: EROL KORKMAZ Habibe Tuğba
Published: January 2022

Bu çalışmada duygusal emeğin öncülleri ve çıktıları incelenmiştir. Duygusal emek, yüzeysel duygusal emek ve derin duygusal emek olmak üzere iki boyut temelinde ele alınmıştır. Duygusal emeği yordamak amacıyla 5-faktörlü kişilik modeli (nevrotiklik, dışadönüklük, deneyime açıklık, uyumluluk, sorumluluk bilinci) kullanılmıştır. Duygusal emeğin çıktısı olarak ise çalışanların psikolojik esenliği (yaşam doyumu, iş doyumu, psikolojik semptomlar) değerlendirilmiştir. Likert-tipi ölçekler içeren anketler kullanılarak hastanelerde görev yapan 230 sağlık çalışanından veri toplanmıştır. Yürütülen bir dizi standart çoklu regresyon analizi sonucunda yüzeysel duygusal emeğin dışadönüklük (+) ve kısmen uyumluluk (-) kişilik boyutları tarafından yordandığı; derin duygusal emeğin ise dışadönüklük (+), uyumluluk (+) ve sorumluluk bilinci (+) tarafından yordandığı tespit edilmiştir. Yüzeysel duygusal emek arttıkça yaşam doyumu azalmaktadır. Derin duygusal emeğin artması ve yüzeysel duygusal emeğin azalması, somatizasyon, depresyon ve hostilite semptomlarında azalma ile ilişkili bulunmuştur. Bu bulgular derin duygusal emeğin çalışan esenliği için faydalı, yüzeysel duygusal emeğin ise zararlı olduğunu göstermiştir. Yürütülen varyans analizi sonucuna göre özel sektör sağlık çalışanları devlet çalışanlarına kıyasla daha fazla duygusal emek sergilemektedirler. Çalışma bulgularının alanyazındaki yeri, örgütlerdeki pratik uygulamalar açısından yapılabilecekler ve çalışmanın sınırlılıkları tartışılmaktadır.

One of the complex technological tasks in the process of drilling is to ensure the stability of the wellbore walls, as well as their modeling for further forecasting the state of the wellbore and the likelihood of hydraulic fracturing. This is due to the fact that most of the complications and factors affecting the equilibrium state of the wall are associated with external influences. The article discusses the mechanical and partially hydraulic aspects of solving the described problems associated with modeling the stability of the wellbore walls and predicting hydraulic fracturing. As a result of calculations, the necessary data are obtained for making a decision on the density of the drilling fluid for drilling the considered interval of rocks. The assumed model of the porous rock and the given calculation formulas make it possible to fully evaluate the influence of the formation fluid pressure on the mechanical processes in the rocks when they are opened by a well. Keywords: hydraulic fracturing; blade bit; steel ball-shaped toothed bit; polycrystalline diamond bit; laser drilling; impact rope drilling; rotary drilling.

The paper presents the possibilities of expanding production opportunities in the oil company PJSC Tatneft. For this purpose, the well No.xxx7g with an inclined pilot borehole was drilled at the Bavlinskoye oil field and oriented core samples were taken to study the lithological cross-section and the geological structure of the subsurface horizons. The horizontal wellbore itself is located in the dankovo-lebedyansky horizon, where multi-zone hydraulic fracturing was carried out through ports with packers there. The following methods will increase the share of recoverable oil reserves in the oldest oil-producing Volga region by starting the development of new productive horizons and increase the oil recovery factors for these reservoirs. The methods used in this work will reduce the unit costs of increasing oil production and achieve a cost-effective level of work on wells of this type. The work had its own peculiarities. One of the reasons for the difficulty in interpreting the hydraulic fracturing Minifrac (Meyer software package) was the rather long time of closing fractures in domanic deposits during the registration of pressure drop. In turn, during the minifrac analysis of the Nolte G Time Test graph showed that the fracture did not close, and therefore it is impossible to determine the closing pressure (the pressure gradient of the gap) with reliable accuracy. Note that when interpreting the flow test results, the best match of the experimental and calculated curves is achieved when using the model of a horizontal well operating a homogeneous reservoir. Also, the deterioration of the bottom-hole zone may be associated with a weak opening of the created fractures. Keywords: oil; well; hydraulic fracturing; unconventionals; fracture; core.

The influence of the electromagnetic field (EMF) on the corrosion of structural carbon steel in a 3% aqueous solution of sodium chloride in the presence of CO2 was studied. It is shown that the EMF increases the corrosion rate of steel by 1.13 times in a 3% aqueous solution of NaCl in the presence of CO2. When Ca2+ ions are added to the solution, the corrosion rate of steel decreases under the influence of an electromagnetic field. It is assumed that the formation of CaCO3 in the near-surface layer of the solution and its adsorption on the metal surface prevents the development of corrosion. The influence of the electromagnetic field generated in the frequency range from 100 to 200 kHz on the crystallization of CaCO3 from supersaturated aqueous solutions on the model system CaCl2 – NaHCO3 – FeSO4 is studied. It was found that Fe2+, rather than EMF, has a more significant effect on salt deposition. The efficiency of the effect of Fe2+ on the inhibition of salt deposition in the model of mineralized water CaCl2-NaHCO3 is 11.5% higher than when exposed to EMF. During the crystallization of CaCO3, the predominant formation of aragonite is observed. In the presence of iron ions and under the influence of EMF, there was a decrease in the formation of aragonite and an increase in the formation of calcite and vaterite. Keywords: electromagnetic field; corrosion; carbon steel; iron ions; scale deposition; crystallization; calcium carbonate.

When developing hard-to-recover hydrocarbon reserves, enterprises use various complexes and systems to facilitate technological processes that contribute to the lifting of heavy and viscous oils to the surface, as well as the extraction of light oils from lowpermeability reservoirs. During the operation of fields, abnormal situations also arise, caused by the appearance of asphalt-resin-paraffin deposits (ARPD) and salt deposits on the walls of tubing pipes, Christmas trees, process pipelines and equipment at the bottom. The existing methods of combating and preventing the manifestations of ARPD and salt precipitation can be conditionally divided into mechanical, chemical, thermal. To prevent and combat ARPD, as well as to reduce the viscosity of produced oils, thermal methods are most preferred, among which electrothermal methods are considered effective. In the case of salt sediments, technologies based on electrical energy are also an effective means of prevention, in particular, exposure of the well emulsion to a magnetic field. Keywords: electrical technological systems and complexes; hard-to-remove oil reserves; asphalt-resin-paraffin deposits; induction heating systems.

Industrial experiment works (IEW) were carried out to study the mechanism of filtration and reservoir properties changes (FRP) in the process of wells swabbing. Based on the hydrodynamic studies, the results of the works are analyzed. A method for oil production enhancing by reservoirs hydraulic compression has been worked out. In the process of well swabbing the barograms were recorded, pressure recovery curves were taken with the determination of hydraulic conductivity and piezoconductivity values, potential productivity coefficients, well flow rate, reservoir pressure before and after exposure. The interpretation of hydrodynamic studies was carried out by the deterministic analysis with subsequent modeling of the situation. The reservoir, opened by the perforation interval, is of complex structure, as a result of which the liquid was absorbed by the interlayer located above the area with newly formed microcracks. Keywords: hard-to-recover reserves; swabbing; carbonate reservoirs; filtration reservoir properties; pressure recovery curve.

The rate of exclusive breastfeeding from 0 to 6 months in Côte d'Ivoire was 16.67 % in 2014. The objective of this study is to identify the difficulties related to the practice of exclusive breastfeeding of infants from birth to 6 months with a view to finding sustainable solutions for its implementation. A survey study was carried out on a sample of 200 women in the municipality of Bingerville from 7 October 2020 to 7 February 2021. After analysis, the results of the survey show that in the Bingerville locality of Côte d'Ivoire, the difficulties relating to the decline in exclusive breastfeeding are largely linked to the insufficient production of breast milk. The results have made it possible to record some species of food plants. They undoubtedly possess lactogenic properties, which make it possible to cope with the insufficient production of milk in the udder. Thus, after 24 hours, these food plants have made it possible to increase the production of breast milk in the udders intended for infants. The registered food plants will help to ensure the food security of the infant through the improvement of milk production in breastfeeding mothers.

Published: January 2022

Background: Obesity and overweight are among serious global epidemics that significantly threaten human health, especially among women. Objectives: This study aimed to assess the concurrent effects of 6-week caffeine supplementation with moderate-intensity aerobic exercise on weight and body fat among overweight women. Methods: Thirty overweight females (age: 36.47 ± 6.48 years; BMI: 27.61 ± 1.54 kg/m2; mean ± SD) with a sedentary lifestyle were recruited to the study. The participants were randomly allocated to the experimental group, EC (exercise + caffeine) group, who took 100 milligrams of caffeine of the “API” brand supplement 30 minutes before exercise training (n = 15) or control group, EP (exercise + placebo) (n = 15). All participants performed moderate-intensity aerobic exercise with an intensity of 40 to 60% of heart rate reserve based on the individual's exercise test for 30 minutes, three days a week for six weeks. Measurements, including the percentage of body fat, waist circumference, and skinfold (suprailiac, abdominal), were done two times, at baseline and after six weeks of exercising. Results: There were no significant differences between control and experimental groups related to weight (P = 0.22), percentage body fat (P = 0.88), and other measurements after six weeks. Conclusions: 6 weeks of caffeine supplementation combined with moderate-intensity aerobic exercise without dietary interventions couldn’t make a significant reduction in weight and central or total body fat among overweight women.

Backgrounds: Molecular mechanisms involved in adverse effects of morphine, including tolerance and dependence, have remained elusive. We examined possible alterations in the gene expression of proenkephalin (Penk), prodynorphin (Pdyn), and mu-opioid receptor (Oprm1) in reward brain areas following frequent morphine treatment. Methods: Two groups of male Wistar rats were used. The groups received either saline (1 mL/kg) or morphine (10 mg/kg) twice daily for eight days. On day 8, rats were decapitated, brain areas involved in addiction were dissected, including the midbrain, striatum, prefrontal cortex (PFC), hippocampus, and hypothalamus, and gene expression was evaluated with real-time PCR. Results: Prolonged morphine treatment decreased Penk, Pdyn, and Oprm1 gene expressions in the midbrain but upregulated them in the striatum compared to the control group treated with saline. Significant increases in Pdyn and Oprm1 gene expressions were detected in the PFC, but there was no significant difference in Penk gene expression between the two groups. Besides, Pdyn gene expression was decreased in the hippocampus and hypothalamus; however, no significant differences in Penk and Oprm1 gene expressions were detected between the groups in these areas. Conclusions: The expression of endogenous opioid peptides and receptors after frequent use of morphine follows a region specificity in brain areas involved in addiction. These alterations may result in new physiological setpoints outside the normal range, which need to be considered when using morphine in medicine.

Background: The COVID-19 crisis has created many problems, including a negative impact on student education. Objectives: The study aimed to understand the resident medical students' performance experiences during the COVID-19 pandemic, which is essential for future planning. Methods: The present qualitative study was performed on 15 resident medical students in Alborz University of Medical Sciences, Iran, from September to November 2020. Data were analyzed using conventional content analysis. Results: Analysis of the meaning units of interviews showed four categories describing the resident students' experiences of performance during COVID-19 as follows: Fear and anxiety, the need for support, the sense of responsibility, and the lack of educational facilities. Conclusions: The present study showed that the COVID-19 pandemic had posed incredible new challenges for resident students. Assessing the mental health of residents, providing adequate protective equipment, and support from authorities and community members can create empathy, reduce the feeling of fear, and increase their accompaniment with pandemic managing programs. Due to the problems created in the training of residents during the pandemic, it seems necessary to propose rehabilitation courses to improve the training program for residents in various fields.
Relationship Between Keloid Pathogenesis and Endothelial Progenitor Cells: A Review Study
Authors: Nishikai-Shen Tsubame-Yan , Tanaka Rica
Published: January 2022

Context: Keloid scars are disfiguring lesions (ie, reddish-brown bulges on the skin surface) formed after a minor injury or surgical invasion. They lead to severe itching or pain, thereby causing physical and psychological distress in patients. Evidence Acquisition: Scholarly databases, including Web of Science, PubMed, and Google Scholar, were searched for relevant articles using keywords such as “keloids,” “endothelial progenitor cells” (EPCs), and “CD34-positive cells.” Results: Keloid scars are classified as an intractable disease; their cause is unknown, and there is no specific therapy. Their pathogenic effects on inflammation around wounds and fibroblasts have been extensively studied. However, details regarding their onset mechanism and definitive factors that contribute to their formation have not yet been elucidated. Adult stem cell therapy, especially regenerative therapy aimed at recovering tissue structure and function, has been extensively studied globally. In our recently published study, we identified an association between keloid scar development and EPCs. However, there is still no systematic review in this regard. Conclusions: This paper provides information on preventing keloids and further understanding the cause of this disease by reviewing previous studies on the association between keloids and EPCs.

Dying today looks dramatically different than it did a century ago, largely due to wider treatment options and more specialized medical practices. Often missing from these advancements is the focus on factors relative to a patient’s total circumstances. Especially in light of the recent pandemic, it is incumbent upon Catholic health care providers to treat who whole person rather than simply focus on more utilitarian philosophies of care.

Published: January 2022

In the spring 2020 semester six students enrolled in a topics course in the philosophy department at my institution titled, “The Poverty Game.” We created this article by collaboration based on fourteen weeks of writing assignments and class discussions. All of us participated in an on-campus poverty simulation “game” sponsored by the Teacher Resource Center. Our objectives in the course were to critically analyze the game by asking questions and challenging assumptions about goals, rules, narrative profiles, and solutions to poverty that were implied by the simulation. We then set about to revise the game. Our suggested revisions highlighted structural conditions as part of an explanation about why populations and subgroups are poor. Identifying these inequities positioned us to recommend justice solutions to poverty and, further, to empower players of the simulation to become agents of change.

Solo con un conocimiento más consciente de los diferentes tipos de big data y sus posibles usos, límites y ventajas la sociología se beneficiará realmente de estas bases empíricas. En este artículo, a partir de una clasificación de los diversos tipos de big data, se describen algunas áreas de uso en la investigación social destacando cuestiones críticas y problemas éticos. Los límites se vinculados a cuestiones fundamentales relativas a la calidad de los big data. Otra cuestión clave se refiere al acceso. Otro aspecto metodológico a tener en cuenta es que los datos digitales en la web deben considerarse no intrusivos. Los métodos de investigación encubiertos ha desafiado la práctica de evaluación ética establecidas adoptadas en la mayoría de las instituciones de investigación: el consentimiento informado. Las pautas éticas digitales no pueden ser universales y estar establecidas de una vez por todas.

Survey Research in Times of Big Data
Authors: Cabrera-Álvarez Pablo
Published: January 2022

La encuesta es la técnica de investigación predominante en la investigación en Ciencias Sociales. Sin embargo, la aparición de otras fuentes de datos como las publicaciones en redes sociales o los datos generados por GPS suponen nuevas oportunidades para la investigación. En este escenario, algunas voces han defendido la idea de que, debido a su menor coste y la velocidad a la que se generan, los big data irán sustituyendo progresivamente a los datos de encuesta. Sin embargo, este optimismo contrasta con los problemas de calidad y accesibilidad que presentan los big data como la fata de cobertura de algunos grupos de la población o el acceso restringido a alguna de estas fuentes. Este artículo, a partir de una revisión profunda de la literatura de los últimos años, explora como la cooperación entre los big data y las encuestas resulta en mejoras significativas de la calidad de los datos y una reducción de los costes.
Nowadays, while surveys still dominate the research landscape in social sciences, alternative data sources such as social media posts or GPS data open a whole range of opportunities for researchers. In this scenario, some voices advocate for a progressive substitution of survey data. They anticipate that big data, which is cheaper and faster than surveys, will be enough to answer relevant research questions. However, this optimism contrasts with all the quality and accessibility issues associated with big data such as the lack of coverage or data ownership and restricted accessibility.  The aim of this paper is to explore how, nowadays, the combination of big data and surveys results in significant improvements in data quality and survey costs.

The retrospective analysis showed that gender, whether having participated in academic education, and the degree of motivation for promotion were major factors that affected the self-learning ability of junior ED nurses (P<0.05). Conclusions The self-learning ability of junior ED nurses in Guangdong is at an intermediate level. Nursing managers should pay more attention to the junior ED nurses with poor self-learning ability. In particular, adopting various training methods and establishing appropriate promotion mechanisms and economic incentive measures may help improve their self-learning ability and enable them to meet job requirements.

Objective To explore the effect of "green channel card" in critically ill patients in emergency department. Methods Seventy-five critically ill patients in the emergency department of our hospital from August 2019 to April 2021 were selected as the experimental group, and 63 critically ill patients from June 2018 to July 2019 were selected as the control group. The experimental group was admitted by using the "green channel card", and the control group was admitted by the green channel signed by the general administrative duty in the hospital. The success rate of emergency rescue, patient satisfaction, waiting time, effective complaints and other related conditions were compared between the two groups. Results The success rate of rescue in the experimental group increased, but there was no statistical significance; while the waiting time in the experimental group was significantly higher than that in the control group (P < 0.05), the patient satisfaction was also higher than that in the control group (P < 0.05); the complaint rate was lower than that in the control group (P < 0.05). Conclusion The use of "green channel card" in emergency critically ill patients can significantly shorten the waiting time for rescue, improve patient satisfaction, reduce the complaints of patients and their families, and make the green channel more efficient, usual and rapid. It is worthy of being widely popularized in the clinical application.

Objective To evaluate the quantitative parameters of carotid elasticity in healthy people and People Living With HIV(PLWH) by ultrasonic vascular elasticity quantitative technique, and to explore the feasibility of this technique in non-invasive evaluation of preclinical arterial elasticity in patients with PLWH atherosclerosis. Methods Subjects with carotid intima-media thickness (IMT) < 1.5mm were divided into three groups: healthy control group (n = 60), HIV baseline group (n = 291) and HAART group (n = 67) with HIV infection who had received highly active antiretroviral therapy ((HAART) for more than 5 years. Quantitative analysis of ultrasonic vascular elasticity was performed in all subjects, and the software automatically quantified carotid artery IMT, artery internal diameter, motion amplitude, vascular hardness coefficient and carotid artery pulse wave velocity,( caPWV), and thean to compare the ultrasonic parameters and blood lipids of each group. In HAART group, the correlation between brachial-ankle pulse wave velocity (baPWV) measured by traditional pressure wave method and caPWV was analyzed. Results Total Cholesterol (TC), triglyceride (TG) and high-density lipoprotein cholesterol (HDL-C) in HAART group were higher than those in baseline group (P < 0.017). Hardness coefficient and caPWV of bilateral carotid arteries in HAART group were higher than those in baseline group (P < 0.017), but the movement amplitude was lower than that in baseline group. In the healthy group, there was no significant difference between the left and right carotid arteries (P > 0.05). In HAART group, baPWV was linearly correlated with caPWV, with the left side correlation coefficient of 0.60 and the right side correlation coefficient of 0.57. Conclusion There is a decrease in preclinical elasticity of carotid artery in patients with PLWH who take antiviral therapy for a long time, and ultrasound vascular elasticity quantitative technique is helpful to identify this change.

Objective Asthma is a common inflammatory disease of the airway, and its underlying mechanism is complex. The role of microRNAs (miRNAs) in asthma is unclear. The present study aimed to investigate miRNA-mRNA regulatory networks underlying asthma. Methods One microarray dataset was downloaded from the Gene Expression Omnibus (GEO) database. Differential expression of miRNAs (DEMs) was identified in bronchial epithelial cells (BECs) isolated from healthy donors and patients with asthma. MiRTarBase, mirDIP, and miRDB were used to predict target genes, followed by protein-protein interaction (PPI) network analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, and Gene Ontology (GO) analysis; cytoHubba was used to predict the important nodes in the network. The miRNA-hub genes sub-network of interest was determined. Results This study constructed an asthma-associated miRNA-mRNA network, in which seven key miRNAs and 10 hub genes were identified. Conclusions The novel miRNAs and hub genes identified in the present study could be potential diagnostic and treatment biomarkers for asthma.

Exploration on Practice Teaching Mode of Law Major in North China University of Technology
Authors: Yu Weizhen
Published: January 2022

After years of exploration and development, our school has implemented various forms of practical teaching methods in the training of law undergraduates, and has achieved certain results, but the phenomenon of theoretical knowledge transmission and ability cultivation still appears to be broken. By sorting out the problems found in the practice teaching of law undergraduate majors in our school, that is, the practice teaching curriculum system is incomplete and the guarantee mechanism is not perfect. Therefore, the practice teaching of law should further improve the relevant systems and strengthen the content and evaluation system of practice teaching. At the same time, a practical teaching platform should be actively established to form a closed-type practical teaching of "theory-simulation-total truth".

In order to achieve the self-sustaining fusion goal of inertial confinement fusion (ICF), extremely strict requirements for the quality of deuterium-tritium(D-T) ice in the target shell have been put forward. The concentricity between the inner surface of the ice and the target shell is required to be greater than 99.9%, and the root mean square (RMS) roughness of the inner surface of the ice is better than 1 μm. The high-quality ICF target is based on the high-quality D-T ice in the target shell. Single crystal is the best form of D-T ice, and seed crystal in target shell is the basic condition. In this paper, the step temperature control method of gradually reducing the heating rate is used to study the retention of seed crystals in the fill tube, and the nucleation mechanism of retention of seed crystals in the fill tube is revealed. The experimental results show that the use of the fill tube defects can keep stable and single seed crystal, and under the same supercooling, when deuterium tritium seed crystal c-axis and the fill tube are axially parallel, the growth rate is about 1–2 orders of magnitude slower than that when the c-axis is perpendicular to the axial direction of the gas filled tube. The results provide a reference for obtaining high-quality seed crystals, and a basic support for developing the D-T target in China.
