Computer vision system for research in the area of defectoscopy for materials and products
Authors:   Lviv Politechnic University, Puyda Volodymyr
Published: December 2022

In many cases, visual and optical methods can be used in defectoscopy for different materials and products. With the development of microprocessor components and significant expansion of usage of computer technologies and image processing and analysis techniques in different areas, the use of visual and optical methods in defectoscopy for production and research purposes is rapidly developing. In this paper, the author proposes a computer vision system for experiments and research in the area of studying defects of materials and products. The system uses modern methods of image processing and object identification based on their images. The system allows to install the object so that it can be rotated horizontally, take high-quality images of the object using a digital video camera, pre- process images to enhance image quality using a local computing module, transfer images to the main computing module to identify defects and make decisions about rejection of the material or product. To install and rotate the material or product, the author uses the stepper motor 17HS4401 and a horizontal platform fixed on the vertical axis. The stepper motor is controlled using Microstep Driver TB6600 and a local computing module based on a microcontroller with an ARM Cortex-M7 core. The video stream is recorded using a USB microscope video camera which provides sufficiently high image resolution allowing to find defects on the object surface of size 50 micron and larger. Rotation speed can be controlled using a local computing module. The input data for the local computing module can be provided in the form of a video stream or a sequence of images. The local computing module has an LCD screen based on the ВС1602А indicator, programmable LEDs, a keyboard to select operating modes for the stepper motor, a USB port to connect the microscope video camera and an SWD port to program the Flash memory and debug the firmware in real time. Original images or the images after quality enhancement are passed to the main computing module using the SPI interface. The author has developed software for the local computing module to control the stepper motor, record a video stream or series of images of the object area with possible defects, quality enhancement and passing the video stream or images to the main computing module for further processing and analysis. The results can be used in scientific research and in development of automated systems for non-destructive defectoscopy for materials and end products.

Authors:   Lviv Politechnic University, Sovyn Ya. R. , Khoma Volodymyr V , Opirskyy Ivan
Published: December 2022

The article is devoted to methods and tools for generating bitsliced descriptions of bijective 4×4 S-Boxes with a reduced number of gates/instructions. Bitsliced descriptions generated by the proposed method make it possible to improve the security and performance of both software implementations of cryptoalgorithms using 4×4 S-Boxes on various processor architectures, as well as FPGA and ASIC based hardware. The paper develops a heuristic method of minimization that uses standard logical instructions AND, OR, XOR, NOT, which are available in most 8/16/32/64-bit processors. Due to the combination of different heuristic techniques (preliminary calculations, exhaustive search to a certain depth, DFS algorithm, refining search) in the method, it was possible to reduce the number of gates in bitsliced descriptions of S-Boxes compared to other known methods. The corresponding software in the form of a utility in the Python language was developed and its operation was tested on 225 S-Boxes of various cryptoalgorithms. It is found that the developed method generates a bitsliced description with a smaller number of gates in 57 % of cases compared to the best known methods implemented in the LIGHTER/Peigen utilities.
Improving the efficiency of SCTP network software
Authors:   Lviv Politechnic University, Feshchenko Zakharii-Andrii , Yurchak Iryna
Published: December 2022

The work presents a software system for demonstrating the operation of the SCTP transport protocol in comparison with its better-known analogues – TCP and UDP. To reproduce the operation of the chosen protocol, a socket API was created that describes the operation of SCTP, based on RFC 6458. It also describes the transport protocols that are similar to the protocol that was chosen to improve performance, namely TCP and UDP, their strengths and weaknesses, and what has been improved in SCTP. A test software model is described, which is divided into a client part and a server part, which was created to demonstrate the operation of the SCTP transport protocol. The client part consists in sending a message to the server, which will read this message and reset it. The ability to send using the SCTP protocol directly, or UDP encapsulation, thus encapsulating the SCTP packet into a UDP datagram, has been developed. The efficiency and expediency of using the software model are shown and alternative software models designed to implement the SCTP protocol are considered. The means used to implement this decision are justified as well as the platforms and operating systems on which this solution can be reproduced, other than Windows.
On assumed usefulness of wearable sensors in early recognition of migraine attacks perceived by patients
Authors: Huttunen Hanna-Leena , Seppänen Pertti , Halonen Raija
Published: December 2022

This study analysed how migraine patients assume to improve their daily life if wearable sensors provide them pre-warnings of approaching or impending migraine attacks. The study analysed the use of new technology in identifying pre-symptoms in migraine patients using the Technology Acceptance Model (TAM) focusing on the assumed usefulness of a wearable device. The study added understanding of getting migraine patients to accept smart technology to support their own treatments. The results were drawn from a sample of altogether 582 migraine patients with or without an aura. The difference between migraine with aura and without aura is that migraine with aura precedes physical symptoms like visual disturbances, numbness, and difficulty in speech, while there are no pre-symptoms in migraine without aura. The assumed wearable device (WBAN) notifies, however, the bio-signals of an oncoming migraine attack.
Due to current achievements with available digitalised tools to monitor health and wellbeing, also self-care is benefiting. Pre-migraine symptoms are among the biggest challenges in identifying migraine. Noting this, our study addressed the value of wearable sensors in early recognition of migraine attacks.

Authors: Koskinen Raija , Helminen Kristiina , Koski Arja , Malkavaara Mikko , Sanerma Päivi , Sihvo Päivi
Published: December 2022

The ethical operational model developed in SotePeda 24/7 project in 2018-2020 has since its launch been used in continuous learning in social and health care. The model was developed to work as a tool in identification of ethical issues in the digitising operational environment of social and health care, as well as to support ethical evaluation and decision-making. When the ethical operational model is embraced, it results into internalizing the reflective process of the model and increases the ability to face ethical dilemmas in the mode of modus operandi indicating socio-culturally established ways of engaging and of doing things.
Our aim in this study is to evaluate the experiences gained of the implementation of the ethical operational model in continuous learning in social and health care. As research methods we apply qualitative evaluation: program theory-based and systems approach. As material of the study, we address the experiences gained from the practical use of the model. Additionally, we scrutinize the ethical operational model as an artefact, as co-constructed object, and make use of the multifaceted data from the time of developing the model.
The results of our study indicate that when the ethical operational model has been systematically used in continuous learning, the experiences have been overall positive, increasing awareness and ethical competence of the participants. From the point of view of its systemic impact, the scrutiny of the ethical operational model as an artefact, indicates that the focal constituents embedded enable even those new to the model to engage in it and to develop the content further via reflection.
We conclude that the ethical operational model has found its way in active use as means of continuous learning in social and health care. The model may gradually become infused in digital era practices and be vitally present in action as modus operandi.
Paljon palveluita tarvitsevien asiakkaiden kokemuksia terveydenhuollon etäpalveluiden mahdollisuuksista terveyden ja hyvinvoinnin edistämisessä ja hoidossa COVID-19 aikana: Laadullinen haastattelututkimus

Published: December 2022

Koronaviruksen leviäminen Suomeen vuonna 2020 joudutti jo käynnissä olevaa terveyspalveluiden digitalisointia. Digitalisaation leviäminen on nostanut riskiä eriarvoisuuden lisääntymiseen eri potilasryhmissä.
Tämän haastattelututkimuksen tarkoituksena oli kuvata paljon palveluita tarvitsevien asiakkaiden kokemuksia terveydenhuollon etäpalveluiden mahdollisuuksista terveyden ja hyvinvoinnin edistämisessä sekä hoidossa COVID-19 aikana. Tutkimuksen tuottamaa tietoa voidaan hyödyntää etäpalveluiden kehittämisessä ja johtamisessa sekä ammattilaisten koulutuksessa.
Tutkimus toteutettiin kuvailevana laadullisena haastattelututkimuksena, joka koostui paljon palveluita tarvitsevien asiakkaiden (n=30) puolistrukturoiduista yksilöhaastatteluista. Haastateltavat valittiin satunnaisotannalla yhden keskisuuren kaupungin asiakasrekisteristä. Haastattelut toteutettiin puhelimitse helmikuun ja toukokuun 2021 välisenä aikana. Litteroidut tekstit analysoitiin induktiivisella sisällönanalyysillä.
Tuloksista muodostui neljä pääluokkaa ja yhdeksän yläluokkaa. Paljon palveluita tarvitsevat toivat esiin etäpalveluiden terveyttä ja hyvinvointia edistäviä mahdollisuuksia, kuten omahoidon mahdollistuminen ja terveyden ja hyvinvoinnin edistäminen etäpalveluilla. Haastateltavien kokemusten mukaan etäpalveluiden saavutettavuuteen vaikuttavia tekijöitä olivat etäpalveluiden helppokäyttöisyys ja saatavuus sekä palveluihin pääsyä edistävät toimenpiteet. Etäpalveluihin liittyvään osaamiseen vaikuttavat tekijät olivat taitoihin tai sairauteen liittyvät haasteet, ohjelmien käytettävyyteen liittyvät haasteet sekä etäpalveluiden koulutuksen ja ohjauksen puuttuminen. Etäpalveluiden käyttöön liittyvät mieltymykset liittyivät henkilökohtaisiin syihin sekä fyysistä läsnäoloa vaativiin asiakkaisiin ja käynteihin.
Johtopäätöksenä voidaan todeta, että etäpalveluiden saatavuus ja käytettävyys sekä paljon palveluita tarvitsevien asiakkaiden digitaalinen osaaminen vaikuttavat etäpalveluiden käyttöön. Etäpalveluita pitäisi kehittää helppokäyttöisemmiksi ja tarjota palveluita monipuolisesti erityisesti niille, joiden digitaalinen osaaminen on riittävä etäpalveluiden käyttöön. Etenkin videovastaanoton mahdollistaminen koettiin tärkeäksi. Lähipalveluita on tärkeää edelleen tarjota niitä tarvitseville.

Authors: Korpela Krista , Korpela Jukka , Virolainen Veli Matti , Huuskonen Heidi , Kanerva Jani
Published: December 2022

Public social and health care organizations everywhere are facing challenges caused by an aging population, declining birth rates, and urbanization. To address these challenges, innovative operating models and flexible IT solutions supporting collaboration between public-sector organizations are required.
Our paper introduces an example of a progressive collaboration model between the Rescue Department of South Karelia (EKP) and South Karelia social and health care district (Eksote), which are frontrunners in the synergy-producing cooperation of rescue board services at the rescue department level with social and health services. The purpose of our qualitative case study is to investigate how Eksote and EKP could further strengthen their public-public partnership (PuP) to improve regional risk management by jointly planning and executing preventive actions and services. The main objectives are to: 1) understand the reasoning behind and the success factors of a public-public partnership; 2) investigate how a joint customer and process management system could support the partnership between a social and health care organization and a rescue department; and 3) identify ways to improve the public-public partnership between a social and health care organization and a rescue department.
This study builds on the existing literature on public-public partnerships by incorporating a customer and process management system into the partnership between a social and health care organization and a rescue department. The empirical data were collected via 16 semi-structured interviews conducted between June 2020 and April 2021. The results indicate that the public sector must determine new and innovative ways of working together to overcome the challenges prevalent in the current operational environment. To support collaborative actions and processes between social and health care organizations and rescue departments, actions are needed on national, regional, organizational, and professional levels. As the public sector is facing similar challenges everywhere, the results can be utilized in Finland and in the international setting.
Scoping review of intergenerational learning methods for developing digital competence and their outcomes
Authors: Hammarén Mira , Jarva Erika , Mikkonen Kristina , Kääriäinen Maria , Kanste Outi
Published: December 2022

Due to the rapid digitalization of healthcare, it is important to strengthen professionals’ digital competence, particularly to support older professionals to stay in work until retirement age. People of different ages have different digital competencies. Younger generations are ‘digital natives’ who have learned to use digital devices fluently from a young age, while older generations have had to learn to use them in adulthood. The increasing number of new technologies causes in some cases stress, especially for more older healthcare workers. Intergenerational learning methods for developing digital competence may offer a way to narrow digital competence gaps in healthcare.
The aim of this scoping review was to identify current evidence regarding intergenerational learning methods for developing digital competence, and their outcomes. The results can be used to help develop methods for intergenerational digital competence development and improve healthcare professionals’ digital competence. A scoping review was conducted across four databases (Scopus, CINAHL, Web of Science, ProQuest) without time limits. The search produced 2905 references, of which 23 studies are included in the review. Thematic analysis was used to analyze these studies’ results.
The results showed that a key method for intergenerational digital competence development is reverse mentoring, where a less experienced person serves as a mentor to a more experienced one. Intergenerational digital competence development methods can be done one-on-one or in groups, in classes or on digital platforms. The outcomes of these methods illustrated that they promote mutual learning, increase the digital competence of older adults and the work life skills of young mentors, and narrow the gap between generations. Using such methods, it is possible to make better use of each generation’s expertise. Intergenerational learning could suggest ways of narrowing the digital gap and enhancing intergenerational communication. Healthcare could benefit from implementing intergenerational learning methods for developing digital competence, increasing the digital competence of healthcare professionals, and narrowing the gap between generations.
Unilateral ‘Sausaging’ of the Stensen's Duct
Authors: Shamova Tetiana
Published: December 2022

A 35-year-old white lady was referred to Kyiv Regional Clinical Hospital for the sialography due to several year history of recurrent swelling of the right parotid gland. A multi-slice computed tomographic sialography of the both parotid glands was performed. A 1-minute postcontrast axial scan shows a dilated right Stensen`s duct with multiple strictures (arrowheads) and dilated intraglandular branches. ‘String of sausages’ appearance represents the ducts` inflammation and terms sialodochitis. But the signs of sialodochitis can be found in several pathologic conditions, like chronic recurrent parotitis and ‘sialodochitis fibrinosa’ (synonym: ‘Kussmaul disease’) and its similar terms ‘eosinophilic sialodochitis’, ‘allergic sialodochitis’. Those terms and others (‘sialodochitis with eosinophilic inflammation’ and ‘idiopathic eosinophilic parotitis’) can be used depending on the countries. For proving and establishing a diagnosis of eosinophilic sialodochitis a cytologic analysis of mucus plugs and ultrasound-guided core needle biopsy are needed and those condition habitually represents bilateral involvement of the parotid and submandibular glands. Unilateral sausaging of the main parotid duct is common for chronic recurrent parotitis in adults. While in children a bilateral intraglandular ducts dilatation is usual with no signs of dilatation of the Stensen`s ducts.

Published: December 2022

Purpose: Today, racial/ethnic differences in the incidence and prognosis of breast cancer (BC) are a well-known fact. This study aimed to examine the distribution of BC molecular subtypes in Turkish women and their relationship with other prognostic clinicopathological variables.

Methods: In our surgical oncology clinic, the database of 480 BC cases was retrospectively scanned between January 2008 and December 2020, and the demographic and histopathological results of the patients were recorded. Patients were classified into five main molecular subtypes. Survival curves were estimated using the Kaplan – Meier method. The relationship between categorical variables was analyzed using the chisquare test.

Results: The mean age of the patients at the time of diagnosis was 54.5 years, 46.3% were premenopausal, the mean tumor size was 28.7 mm, most of them were T1 (54%), ER, PR, HER-2 positivity rates were 79.6%, 73.1%, 38.3%, respectively and Ki-67 index average was 31.6. The most common molecular subtype was Luminal B Her2B-(33.5%). During a mean follow-up period of 56.9 months, 5 and 10-year overall survival (OS) rates were 89.5%, 79.6%, respectively, and disease-free survival (DFS) rates were 86.9%, 70.5%, respectively. The recurrence rate was 12.3%, distribution by molecular subtypes was significant (p=0.02). Luminal A and Luminal B/Her2- were in relation with Lobular Carcinoma (p=0.005), low histological grade (p=0.00), small tumor size (p=0.00), absence of lymphovascular invasion (LVI) (p=0.00), breast conserving surgery (p=0.022), presence of menopause (p =0.005) and local disease (p =0.013).

Conclusions: This study showed that there are differences in molecular subtyping for symptomatic BC in Turkish women.

This clinical trial was planned to examine the long-standing clinical achievement of dental implants equipped either with cemented or screw-retained systems. A total of 100 teeth were selected based on the following inclusion criteria: should have a particular implant by means of cement and screw implant prosthesis, participants should have superior oral hygiene, non-alcoholic and non-smoker patients, and aged between 20 - 65 years. They were separated into two groups; 50 teeth were cemented (group A) and 50 by a screw (group B) system. At least 24 months evaluation was integrated to measure the periodontal pocket depth. Statistical analysis was done by using SPSS (Statistical Package for Social Science) where comparisons were assess by using the Chi-square test, Fisher's exact test; a P-value <0.05 was considered significant. It was found that at six months, periodontal pocket depth was increased in 2.0% of teeth in Group-A, but none in Group-B. Periodontal pocket depth increased significantly in group A (20%) at 12 months comparing to group B (4.0%). In the same way, at 18 and 24 months, teeth in group-A had significantly higher periodontal pockets (64.0% and 84.0%, respectively) than in group-B (8.0% and 32.0%, respectively). It can be stated that comparing to the cemented implant, the screw implant prosthesis perform better in terms of their periodontal pocket depth.
Acquired Oral Syphilis Guidelines for Dental Practitioners: Two Case Studies and A Literature Review
Authors: Becker Talia , Yefet Evyatar , Intrater Shir
Published: December 2022

The clinical features of syphilitic lesions in the oral mucosa are variable, and there are no specific guidelines in the scientific English literature for dental practitioners regarding oral signs and symptoms that mandate serological tests for syphilis. We performed an updated review of reports on protocols for managing acquired oral syphilis (AOS) and offer recommendations with an emphasis on clinical features. We also add two new cases from our own files. Our analyses of global reports revealed that males are significantly more often affected than females, and their mean age is higher. Young adults are most affected, with a peak in the third and fourth decades of life. Ulcers and mucous patches as manifestations of AOS are the most prevalent clinical features in the oral mucosa. Mucous patches are significantly more prevalent in females as compared to males and tend to present as multiple rather than isolated lesions, while ulcers frequently appear as a sole lesion. The tongue, lip, and palate are the most affected anatomical sites. New oral lesions in the context of unprotected sexual intercourse warrant serological testing for syphilis.

Published: December 2022

The objective of this study was to compare the volume of three-dimensional (3D) models generated by different scanners and computational modeling protocols. Eight dry mandibles were scanned by five different computed tomography (CT) scanners and by a 3D-scanner. Three-dimensional models were generated, received different surface treatment processes, and the final volume of the 3D models was compared. The results show that there was no significant difference among the volume of the 3D models generated by the different CT scanners and surface treatment techniques, however, the model volume generated by the 3D-scanner show the highest volume. It can be concluded that the different combinations of surface treatment protocols did not determine differences in the model volume generated by different CT and CBCT scanners and that the 3D-scanner determined the highest volume models.

Published: December 2022

When a fault on a transmission line manifests itself, the reliability of the power system is often compromised. It is advantageous to be able to stop certain faults from happening or to identify their causes when they do. The system may be quickly returned to its regular functioning condition by knowing the location of any possible line faults. This study proposes a method for fault localization based on travelling waves. This technique makes use of the currents and voltages coming from the line, as well as the speed of propagation, capacitance, inductance, the length of the transmission line, and the change in time that the fault occurs, in order to locate the specific site of the problem. The Onitsha to New/Haven 96 km transmission line was employed as a case study, and Matlab/Simulink was used to model, simulate, and apply the travelling wave fault detection equation. After simulating several fault sequences, the locations of the single line to ground fault, double line to ground fault, line to line fault, and three phase fault were found to be 48.539625306645 km, 48.539625261133 km, 48.539624540792 km, and 48.539625285965 km, respectively.

Authors: Saltas Vassilios , Tsiantos Vassilios , Varveris Dimitrios
Published: December 2022

The purpose of this work is to define the Laplace transform and the Laplace inverse transformation, to describe their basic properties and to calculate the corresponding transforms of selected functions. To achieve these, the concept of the real function image is first defined, and in particular the conversion of the complex variable function. The examples used are initially pure mathematics, followed by reference to the practical application of these two transformations since they relate to the conversion of a continuous time signal into a complex variable function.
Direct Proof for Fermat's Last Theorem using Ramanujan-Nagell Equation
Authors: Seetharaman Palamadai N.
Published: December 2022

Fermat’s Last Theorem states that it is impossible to find positive integers A, B and C satisfying the equation:
An + Bn = Cn
where n is any integer > 2.
Taking the proofs of Fermat for the index n = 4, and Euler for n = 3, it is sufficient to prove the theorem for n = p, any prime > 3 [1].
We hypothesize that all r, s and t are non-zero integers in the equation:
rp + sp = tp
and establish contradiction.
Just for supporting the proof in the above equation, we have another equation:
x3 + y3 = z3
Without loss of generality, we assert that both x and y as non-zero integers; z3 a non-zero integer; z and z2 irrational.
We create transformed equations to the above two equations through parameters, into which we have incorporated a Ramanujan-Nagell equation. Solving the transformed equations, we prove the theorem.

Authors: Gaikwad Bhavna B. , Rane Bhushan R. , Jain Ashish S.
Published: December 2022

Oral administration of dosage form is the most recommended mode of administration, because of its self-medication, accurate dose of the drug, and ease of administration. However, trouble swallowing in geriatric patients is one major negative of this route, which can mentally disrupt patients. The goal of this study was to use the direct compression method to make orodispersible tablets of sulindac utilizing various doses of super disintegrant agents such as Sodium starch glycolate Crospovidone and Croscarmellose sodium. Three distinct super disintegrants were used to create nine formulations with varying concentration levels. The preformulation, precompression, and post-compression properties of the powder combinations were assessed. In comparison to the other formulations, tablets from batch F3 containing crospovidone had superior organoleptic qualities, as well as outstanding drug release and in-vitro disintegration time. The super disntegrants addition technique was shown to be a viable method for manufacturing orodispersible tablets using the direct compression method.
Biomedical science limitations and flaws: why not choose wisely?
Authors: Cavezzi Attilio , d'Errico Giovanni , Colucci Roberto
Published: December 2022

Biomedical science is experiencing a reassessment of its practices of healthcare management where more appropriate cost-benefit profiles are being combined with improvements in knowledge, effectiveness, and safety of diagnostic/therapeutic procedures to drive the advances in medicine. This review aims to assess: (a) possible biases of the scientific literature and research, (b) the clinical value and the cost-effectiveness of the principal medical practices and (c) the possible contribution of integrative and translational medicine.
Literature shows that current medical research has cognitive (mostly industry-induced) biases that negatively impact clinical practice: the ever-increasing use of drugs and technologies, united with a certain inattention to the basic mechanisms of pathophysiology are paving the way of reductionism in medical practice. A critical view of innovations in medicine, together with a sound understanding and application of the scientific method, would improve the effectiveness, safety and sustainability of therapies.
Translational and integrative medicine can contribute to develop a new patient-centered approach. Conversely, reductionism, eminence/reimbursement-based medical decisions, lack of patient education, industry-influenced science, and limited awareness from physicians may compromise the efficacy, safety, appropriateness, and cost-effectiveness of diagnostic and therapeutic processes.

Published: December 2022

Recent studies found that a city confinement as a result to Covid-19 outbreak resulted on eating and lifestyle behavior changes. This study investigated the influence of lockdown on eating and life style changes.  A cross-sectional study was done from December 18, 2021, to February 20, 2022.  The research composed of three parts. Part I  (6 questions) contained socio-demographic statues; section two (11 questions) studied dietary behavior through that included) a Mediterranean diet (MD) adherence using 14-scaled items with an MD screener tool ranging from 0 to 13; and section three (12 questions) studying lifestyle habit changes such as physical activity, sleeping habits, and smoking habits. The results showed that, 17% (63) of individuals that believed their lifestyle had improved, while 38.6% (143) stated it had worsened. Specifically, during lockdown, the physical activity frequency seems  reduced from 50% (185) to 33% (127), and sleeping hours for those sleeping more than 9 hours were dramatically raised from 17% to 31.4%. In terms of eating habits, 36.8% of participants stated appetite improvement, whereas 22.7% reported a decrease. The appetite change during confinement  was not connected with body mass index, although it was significantly associated with weight change (p =0.0001). Similarly, 47% of participant said they had gained weight. The data also showed that 67% (248) medium adhered to MD diet. Thus, the Covid-19 lockdown has negatively affected both lifestyle and eating behavior of the students.

A review of Ireland’s Local Property Tax
Authors: Turley Gerard
Published: December 2022

Property taxes are common in countries around the world. Until recently, Ireland was an exception as there was no annual tax on residential property. This paper is a review of the Local Property Tax (LPT) system that was introduced in 2013 and had its first property revaluations in 2021. Using the lens of municipal finance and tax assignment, the rationale, history, features and administration of this new residential property tax are outlined. While recognising country-specific circumstances, lessons, opportunities and challenges are explored with a view to future improvements in the design and implementation of the LPT. Lessons from the LPT experience are the importance of tax administration and the role of the central tax collection agency, and, in terms of design, the need for a tailored approach to suit local circumstances. Challenges include the rates/LPT mix and the relative tax burdens on non-residential and residential properties, the long-term sustainability of the LPT arising from design issues, the current low tax rate and future revaluations, and, finally, the need for regular property tax reform because of political and taxpayers’ opposition to a highly visible, unpopular but good local tax.
An empirical research on economic growth from industrial structure optimisation in the Three Gorges Reservoir area
Authors: Tao Yi , Zeng Qingjun , Wu Youbo
Published: December 2022

Using the panel data of industrial structure and economic growth (EG) in eight key districts and counties in the Three Gorges Reservoir area from 2011 to 2019, EG was used as the explained variable, and industrial structure optimisation was used as the explanatory variable; technological innovation (TI), FTL, FCI and budgetary expenditure (BE) were used as the control variables. Empirical research on whether the industrial structure can have an impact on the EG of the reservoir area was carried out. The research results showed that optimisation of the industrial structure in the reservoir area plays an important role in promoting EG, and the investment of fixed capital and BE has a significant positive impact on the EG of the reservoir area, whereas the level of TI and foreign trade have no important role in promoting EG.
University-Community Engagement: Formation of New Collaboration Patterns in Participatory Budgeting Process
Authors: Treija Sandra , Bratuškins Uģis , Koroļova Alisa
Published: December 2022

Promoting public participation in urban processes has long been a critical issue in discussions about urban governance. However, despite the advantages of more progressive and inclusive city governance, participatory budgeting (PB) often faces challenges in ensuring collaboration between different stakeholders involved. Not always do the involved parties have adequate resources to lead the brainstormed ideas to a tangible project application. In recent decades universities are supporting partnerships, grassroots projects and media conversations to take an active part in the development of cities. In addition to the wish of making research results available to a wider public and increasing the chances of making use of them, universities are also interested in the co-production of knowledge with non-academic groups. This makes universities an important stakeholder with a potential of supporting community engagement processeses. Thus, through the analysis of participatory budgeting processes in the cities of the Eastern Baltic Sea region and a detailed case study of participatory budgeting in Riga, this research explores the limits of current PB programs, motivations and advantages of involving university in this process.

Multi-photon time-of-flight MLEM application for the positronium imaging in J-PET
Authors: Shopa Roman Y. , Dulski Kamil
Published: December 2022

We develop a positronium imaging method for the Jagiellonian PET (J-PET) scanners based on the time-of-flight maximum likelihood expectation maximisation (TOF MLEM). The system matrix elements are calculated on-the-fly for the coincidences comprising two annihilation and one de-excitation photons that originate from the ortho-positronium (o-Ps) decay. Using the Geant4 library, a Monte Carlo simulation was conducted for four cylindrical 22Na sources of β+ decay with diverse o-Ps mean lifetimes, placed symmetrically inside the two JPET prototypes. The estimated time differences between the annihilation and the positron emission were aggregated into histograms (one per voxel), updated by the weights of the activities reconstructed by TOF MLEM. The simulations were restricted to include only the o-Ps decays into back-to-back photons, allowing a linear fitting model to be employed for the estimation of the mean lifetime from each histogram built in the log scale. To suppress the noise, the exclusion of voxels with activity below 2% – 10% of the peak was studied. The estimated o-Ps mean lifetimes were consistent with the simulation and distributed quasi -uniformly at high MLEM iterations. The proposed positronium imaging technique can be further upgraded to include various correction factors, as well as be modified according to realistic o-Ps decay models.
