The impact of Special Economic Zones on local labour markets in Poland
Authors: Ambroziak Adam A. , Dziemianowicz Wojciech 
Published: January 2021

Abstract
Studies conducted so far suggest that SEZs are not treated by local authorities as the main mechanism of job creation in a given region. The objective of this paper is to highlight potential mechanisms through which SEZs impact labour markets in poviats (counties) in Poland. To this end we conducted a comparative analysis of changes that had taken place in the labour market over the period 2004–2016 in two groups of poviats with the highest unemployment rate reported in 2004: with and without SEZs. The study does not allow us to unambiguously conclude that SEZs contributed to the improvement of labour market situation in poviats with the highest unemployment rate in Poland. That can be attributed to the fact that SEZs in Poland are highly fragmented as well as to SEZs investors being able to select locations for their investment projects in relatively better developed regions.

Published: January 2021

Abstract

Introduction: Magnetic Resonance Spectroscopy (MRS) is a very powerful tool to explore the tissue components, by allowing a selective identification of molecules and molecular distribution mapping. Due to intrinsic Signal-to-Noise Ratio limitations (SNR), MRS in small phantoms and animals with a clinical scanner requires the design and development of dedicated radiofrequency (RF) coils, a task of fundamental importance. In this article, the authors describe the simulation, design, and application of a 1H transmit/receive circular coil suitable for MRS studies in small phantoms and small animal models with a clinical 3T scanner. In particular, the circular coil could be an improvement in animal experiments for tumor studies in which the lesions are localized in specific areas.

Material and methods: The magnetic field pattern was calculated using the Biot–Savart law and the inductance was evaluated with analytical calculations. Finally, the coil sensitivity was measured with the perturbing sphere method. Successively, a prototype of the coil was built and tested on the workbench and by the acquisition of MRS data.

Results: In this work, we demonstrate the design trade-offs for successfully developing a dedicated coil for MRS experiments in small phantoms and animals with a clinical scanner. The coil designed in the study offers the potential for obtaining MRS data with a high SNR and good spectral resolution.

Conclusions: The paper provides details of the design, modelling, and construction of a dedicated circular coil, which represents a low cost and easy to build answer for MRS experiments in small samples with a clinical scanner.
Feasibility Study of Rans in Predicting Propeller Cavitation in Behind-Hull Conditions

Published: January 2021

Abstract
The propeller cavitation not only affects the propulsive efficiency of a ship but also can cause vibration and noise. Accurate predictions of propeller cavitation are crucial at the design stage. This paper investigates the feasibility of the Reynolds-averaged Navier–Stokes (RANS) method in predicting propeller cavitation in behind-hull conditions, focusing on four aspects: (i) grid sensitivity; (ii) the time step effect; (iii) the turbulence model effect; and (iv) ability to rank two slightly different propellers. The Schnerr-Sauer model is adopted as the cavitation model. A model test is conducted to validate the numerical results. Good agreement on the cavitation pattern is obtained between the model test and computational fluid dynamics. Two propellers are computed, which have similar geometry but slightly different pitch ratios. The results show that RANS is capable of correctly differentiating the cavitation patterns between the two propellers in terms of the occurrence of face cavitation and the extent of sheet cavitation; moreover, time step size is found to slightly affect sheet cavitation and has a significant impact on the survival of the tip vortex cavitation. It is also observed that grid refinement is crucial for capturing tip vortex cavitation and the two-equation turbulence models used – realizable k-ε and shear stress transport (SST) k-ω – yield similar cavitation results.

Abstract
Maritime shipping is a key component of the global economy, representing 80–90% of international trade. To deal with the energy crisis and marine environmental pollution, hydrogen-natural gas-diesel tri-fuel engines have become an attractive option for use in the maritime industry. In this study, numerical simulations and experimental tests were used to evaluate the effects of different hydrogen ratios on the combustion and emissions from these engines. The results show that, in terms of combustion performance, as the hydrogen proportion increases, the combustion ignition delay time in the cylinder decreases and the laminar flame speed increases. The pressure and temperature in the cylinder increase and the temperature field distribution expands more rapidly with a higher hydrogen ratio. This means that the tri-fuel engine (H2+CH4+Diesel) has a faster response and better power performance than the dual-fuel engine (CH4+Diesel). In terms of emission performance, as the hydrogen proportion increases, the NO emissions increase, and CO and CO2 emissions decrease. If factors such as methane escape into the atmosphere from the engine are considered, the contribution of marine tri-fuel engines to reducing ship exhaust emissions will be even more significant. Therefore, this study shows that marine hydrogen-natural gas-diesel tri-fuel engines have significant application and research prospects.
Mental Disorders Following Covid-19 Infection: A Systematic Review of Acute and Long-Term Psychiatric Manifestations and Associated Brain Changes
Authors: Fischer Paale Ruben , Renemane Lubova 
Published: January 2021

Abstract
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) primarily affects the respiratory tract, but sometimes also other organs, including the central nervous system (CNS). It is not well understood how the virus affects the CNS and how frequently it happens. Our review provides insight into the occurrence of mental disorders in Corona Virus Disease 2019 (COVID-19) patients. We also collected information about the biological basis of the susceptibility of brain cells to SARS-CoV-2 and its implication to psychiatric manifestations. We included 24 publications in our review, reporting psychiatric manifestations published between 31 December 2019 and 30 July 2020, using the Preferred Reporting Items for Systemic Review and Meta-Analysis statement. Mental disorders occurred in up to one-fifth of patients during the acute phase of the infection. The most common disorders included anxiety-related disorders, mood-spectrum disorders, impaired consciousness, confusion, delirium and psychosis. The onset of psychiatric manifestations is not always preceded by respiratory symptoms, but occurs initially in COVID-19 patients. Long-term manifestations are mainly depression and post-traumatic stress symptoms. The obtained data allow the statement that direct infection of the CNS by SARS-CoV-2 could be responsible for the observed findings. To further investigate long-term psychiatric manifestations, randomised controlled studies must be initiated.
Unity in Variety. Employment Dynamics and Specialisation Profiles of Medium-Sized Towns in the Asti-Rovigo Area, Italy (2001–2017)
Authors: Clerici Maria Antonietta 
Published: January 2021

Abstract
We still know relatively little about the processes of economic transformation in medium-sized towns, which are the cornerstone of the settlement system of many rural areas, together with small towns. This paper considers a group of 39 towns in Northern Italy, located in the area between Asti and Rovigo. Using data from the Italian National Institute of Data Statistics (ISTAT), we investigated the dynamics of the number of the employed at businesses in the periods of 2001–2011 and 2012–2017, the different specialisations of the towns and their ability to attract employees within the respective employment areas. Locally differentiated performance and evolutionary trajectories are evident, preventing us from being able to think of medium-sized (but also small) towns as a coherent whole. It is also clear how the drive towards centralising employees in towns increased following the Great Recession.

Published: January 2021

Abstract

Background
Cystoscopy in complement with urinary cytology represents the gold standard for the follow-up of patients with urinary bladder tumours. Xpert Bladder Cancer Monitor Test (XBC) is a novel mRNA-based urine test for bladder cancer surveillance. The aim of the study was to evaluate the performance of the XBC and voided urinary cytology (VUC) in the follow-up of bladder tumours.

Patients and methods
The XBC was performed on stabilized voided urine and VUC was performed on urine samples. The results were compared to cystoscopic findings and histopathological results after transurethral resection of the bladder lesion.

Results
For the prediction of malignant histopathological result sensitivity, the specificity and negative predictive value were 76.9%, 9 7.5% and 93.0% for the XBC and 38.4%, 9 7.5% and 83.3%, respectively for VUC. For the prediction of suspicious or positive cystoscopic finding sensitivity, the specificity and negative predictive value were 75.0%, 95.2%, and 93.0% respectively for the XBC and 41.7%, 97.6%, and 85.4% for VUC. The sensitivities for papilary urothelial neoplasms of low malignant potential (PUNLMP), low- and high-grade tumours were 0.0%, 66.7% an d 100.0% for the XBC and 0.0%, 66 .7% and 42.9%, respectively for VUC.

Conclusions
The XBC showed significantly higher overall sensitivity and negative predictive value than VUC and could be used to increase the recommended follow-up cystoscopy time intervals. Complementing the XBC and voided urinary cytology does not improve performance in comparison to the XBC alone.

Published: January 2021

Abstract
Genetic diversity and the optimal genetic composition are essential for the adaptability and adaptation of tree populations. Artificial regeneration of stands might reduce the genetic diversity and increase family structures if the seeds were collected from a limited number of mother trees. We did a genetic inventory in 12 pedunculate oak stands in Russia using a set of 366 nuclear gene markers (361 SNPs, 5 Indels) in order to look for differences in the genetic composition among natural and artificial stands. Our results did not reveal any systematic differences among both types of stands. However, we found two extreme cases of limited genetic diversity and increased proportion of full-sibs and half-sibs in urban man-made stands. The implications for the forestry and gene conservation programs were discussed.

Published: January 2021

Abstract

Introduction
National and international research results have highlighted the fact that workplace stress causes mental and somatic problems. The aim of the present paper is to define exposure to workplace-related risk factors, with special focus on psychosocial risk factors, and the way they interconnect with workplace conditions, relationships with superiors and colleagues, and moral, professional and financial appreciation.

Methods
Cross-sectional research with the help of an anonymous online self-administered questionnaire was carried out among 261 higher education employees (67% women, 33% men, mean age 43.4 years) from 12 faculties of the University of Szeged, Hungary. Statistical analysis was performed using IBM SPSS 22.0.

Results
The primary workplace stress factors for university employees were strict deadlines (80.4%), frequent overwork (64.2%) and difficulty in meeting requirements (56.7%). Communication problems with colleagues and superiors were also highlighted (47.5%). Job strain was higher for women than for men. With regard to low financial, professional, and moral appreciation, employees were characterised by the existence of work requirements impossible to meet, as well as by low autonomy. Experience of anxiety and aggression came along with low financial and moral appreciation (p<0.001).

Conclusions
Our data suggests that employees at the university were subject to several psychosocial risk factors, and worked under considerable mental stress, leading to a higher prevalence of mental health problems. The results highlight the need for a health-focused policy-making in higher education to reduce health expenditure and increase efficiency at work.

Our heuristic predicts a similar asymptotic if C is replaced with any similar fractal with a description in terms of missing digits in a base expansion. Interest in the growth of N∗
(T)is motivated by a problem of Mahler on intrinsic Diophantine approximation on C.

Literatura hiszpańskojęzyczna o władztwie religii katolickiej nad ciałem osób duchownych i konsekrowanych
Authors: Grzyś Olga 
Published: January 2021

Catholic religion presents an ambivalent attitude towards the body: it adores the tormented and resurrected body of Christ, but rejects human physicality, regarding it as a cause and consequence of sin. Such conviction led to imposing numerous restrictions on almost all life spheres of priests, nuns and monks. They cannot get around, get dressed or decide about their activities and relationships freely. They subject their bodies to mortification, vowing celibacy and sexual abstinence. However, a desire to marginalise the physical sphere of human life, which was rooted in the Church, has produced the opposite result. As a consequence, the body became the centre of interest not only for clergymen and believers, but also writers, poets and artists from different countries and periods. The paper focuses on the literature of Spanish‑speaking countries, searching for references to the methods of bodily discipline among clergymen and consecrated people. The abundance and variety of presented examples point to the fact that this topic is worth of interest and a deeper analysis.
LEGAL PROTECTION ON FEMALE WORKERS SUBJECT TO HARRASSMENT IN WORK RELATIONS
Authors: Tobing Christina NM 
Published: January 2021

This study aims to describe the legal protection in the field of labor in Indonesia for female workers who had experienced harassment in work relationships.The research method used is normative juridical through statute approach, conceptual approach and case approach Baiq Nuril. The data source is in the form of primary legal materials, namely the Manpower Act, the PPHI Law, the ITE Law, the Criminal Code, the Human Rights Law and the MA Decision No. 574 K / Pid.Sus / 2018, also secondary legal materials in the form of the PKS Draft Bill, books, papers and journals that contain views and doctrines developed in the science of law.The results of the study showed that the Manpower Act had not yet provided the rights of women workers to protect their morals and decencies, as well as treatment that was in accordance with human dignity and religious values in work relations according to human rights. The status of honorary workers in government agencies became unclear after the enactment of the ASN Law. The UUK and PPHI Law cannot be applied in the case of honorary worker Baiq Nuril, because it does not include the legal subject of employer government agencies. The rights of workers detained during criminal proceedings cannot be prosecuted in the Industrial Relations Court as a manifestation of the presumption of innocence principle. Legal protection for female workers who experience non-verbal sexual harassment is not regulated in the Indonesian Criminal Code or in other criminal laws, so that their human rights cannot be maintained before a criminal court. The PKS Draft Bill has included non-verbal sexual harassment as a form of protection for women, therefore it needs to be authorized by the Parliament immediately.
Chemotherapy-induced changes in tumor consistency can allow gross total resection of previously unresectable brainstem pilocytic astrocytoma
Authors: Chung Douglas J. , Arif Bilal , Odia Yazmin , Siomin Vitaly 
Published: January 2021

Background:
Low-grade gliomas (LGG) are described by the World Health Organization as Grades I and II. Among LGGs, the most common primary brain tumor is pilocytic astrocytoma (PA) and carries an excellent prognosis when treated with complete surgical resection. Cases, in which this is not possible, are associated with less favorable outcomes and worse progression-free survival.

Case Description:
This report describes a case of a 22-year-old male, who presented with progression of a primary brainstem tumor previously treated with stereotactic radiosurgery and chemotherapy. Patient underwent surgical exploration and was diagnosed with juvenile PA, but debulking was limited by the very dense and fibrous tumor. Complete surgical resection was not possible at this time. Despite efforts to treat with chemotherapy, the patient presented a year later with clinical deterioration and severe neurologic deficits, prompting surgical re-exploration. During the second operation, the tumor was found to have undergone very significant softening in consistency, allowing for gross total resection (GTR)

Conclusion:
Aggressive treatment of brainstem LGG should be pursued whenever possible, given its generally favorable prognosis. Repeat microsurgical resection, even with a different approach, might be reasonable and safe. Finally, chemotherapy may be associated with changes in the tumor consistency that can render previously unresectable lesions amenable to successful aggressive resection.
Unilateral posterior reversible encephalopathy syndrome characterized with a long and gradually exacerbating course over 3 years and that presented propofol infusion syndrome – A case report

Published: January 2021

Background:
Posterior reversible encephalopathy syndrome (PRES) is characterized by acute neurological symptoms and vasogenic edema, and most patients wholly recover. We report a unilateral PRES patient characterized by a gradual onset followed by propofol infusion syndrome (PRIS) due to general anesthesia therapy.

Case Description:
A 32-year-old woman had ovarian dysfunction treated by Kaufmann’s treatment for 17 years. Three years ago, she developed seizures, and photophobia and myoclonus sometimes occurred. This time, she had strong photophobia and nausea for 3 months and then developed tonic-clonic seizures for 3 min. Her blood pressure and laboratory test on admission were all within normal limits. She presented no neurological deficits at admission, but the T2-weighted image (T2WI) showed a high-intensity area (HIA), and arterial spin labeling (ASL) image described cerebral blood flow (CBF) increase in the left parieto-occipital region. We diagnosed PRES and started anticonvulsants, antihypertensive, and steroid pulse therapy. However, her aphasia and neuroimaging findings worsened, so we started general anesthesia treatment with propofol on day 29. On day 32, she suddenly developed multiple organ dysfunctions due to PRIS. After intensive care with other sedatives over 2 months, the systemic status and neurological symptoms gradually improved almost as before the onset. On day 90, HIA in the T2WI in the lesion became small, and CBF was severely downregulated in the ASL image.

Conclusion:
Unilateral PRES’s pathophysiology and the association with the female hormone remain unknown. Some patients undergo gradual onset and long-term courses, and we should care for PRIS during PRES treatment.
