El ius fiscale constituye un sector del ordenamiento jurídico romano que no ha sido demasiado estudiado, no obstante, la clasicidad y modernidad de sus principios informadores, la conservación de una parte importante de su léxico y la actualidad de muchos de los instrumentos de política tributaria. En las ciudades estado áticas, en la Roma republicana y en la etapa imperial, se encuentran las primeras manifestaciones de una Hacienda pública ordenada, con una actividad financiera estructurada en impuestos directos e indirectos, y con principios, normas e instituciones basados en el interés general.
Utilitas publica, ius naturale y protección de la natura
Authors: Fortunat Stagl Jakob
Published: June 2023

¿Cuál es la función de la categoría utilitas publica en los escritos de los juristas clásicos? Esa es una pregunta que abordaremos en este escrito, ya que esta categoría en primer lugar, sirve para legitimar las leges publicae, como en el caso de la lex Iulia et Papia de Augusto. En segundo lugar, utilitas publica se cita como la razón de ser de una lex publica dada para el propósito de su interpretación, y en tercera instancia, es una guía para la creación de una nueva ley por parte de los propios juristas. La parte del derecho romano que se deriva de la utilitas publica se llama ius publicum. En este sentido tiene una función selectiva. Debido a su origen en el pensamiento iusnaturalista y su naturaleza pública, la utilitas publica es el principio creativo detrás de las primeras normas de protección del medio ambiente.

Authors: Munguambe Carlos , Coultas Mimi
Published: June 2023

Antes da COVID-19, o protocolo de Saneamento Total Liderado pela Comunidade de Moçambique (STLC), introduzido em 2008 e referenciado na Estratégia de Saneamento Rural 2021-2030, amplamente alinhado com a abordagem original proposta por Kar e Chambers no Manual de STLC (2008). Incluía actividades participativas de pré- activismo e pós- activismo, reunindo comunidades inteiras para promover a mudança de comportamento colectivo em matéria de saneamento e saúde na comunidade. Durante a pandemia, o UNICEF Moçambique trabalhou com o Governo de Moçambique (GdM) e outros parceiros para adaptar o protocolo de STLC de acordo com as restrições governamentais para apoiar a implementação contínua da abordagem. Com as restrições agora reduzidas, é necessária clareza sobre um protocolo STLC pós-pandémico. Este estudo rápido analisou como a programação de STLC foi adaptada e implementada durante a pandemia e os sucessos, fracassos e lições aprendidas, com vista a informar as recomendações a prosseguir. Com apenas 8 anos para alcançar os ODS, é oportuno para Moçambique rever e adaptar os instrumentos existentes para assegurar a aceleração necessária para a eliminação do fecalismo a céu aberto.

Published: June 2023

The aim of this study is to investigate radioactive pollutants from pollution loads transported from the Black Sea to the Aegean Sea by the Turkish Straits System and their effects on microfauna (benthic foraminifer and ostracod) assemblages. In the study, the effects of gross alpha and beta activity on the species number, species diversity, dominant species and species richness of benthic foraminiferal and ostracod assemblages were investigated in 16 bottom sediments taken from different depths in the Golden Horn, Bosphorus and Dardanelles straits. In the studied sediment samples examined 61 genera and 64 species of benthic foraminifera, 23 genera and 26 species of ostracoda were identified. In addition two migratory foraminifera species were observed as Spiroloculina antillarum of Atlantic-Pacific origin and Peneroplis pertusus of Indo-Pacific origin. A relationship between the abundance of microfauna and high gross alpha and beta values was found in the Dardanelles samples, but not in the Bosphorus and Golden Horn samples. In this study, the highest radioactivity value was observed in the deepest bottom sediment samples. Consequently, the gross alpha and beta values were seen to be close to each other in the Dardanelles Strait and Golden Horn samples, and they had a broad-spectrum in the Bosphorus samples.
La efectividad de los derechos sociales en el empleo de hogar y de cuidados en España desde la perspectiva del destinatario del derecho. Algunas innovaciones en la elaboración normativa y en los medios de tutela
Authors: Vila-Viñas David
Published: June 2023

El artículo analiza el sector de las empleadas de hogar y de cuidados en España. Muestra las dificultades de acceso a derechos sociales y el impacto de la crisis del covid sobre sus ingresos y acceso a una vivienda. Analiza la eficacia de las garantías sobre sus derechos sociales, tanto generales, como más específicos: subsidio extraordinario e ingreso mínimo vital. En ambos planos se identifican problemas de eficacia. Ello contrasta con la eficacia aportada por las estrategias de autotutela, desplegadas desde las propias organizaciones de empleadas de hogar. Todo ello permite reflexionar sobre los cambios que debe introducir el derecho en la categorización de grupos sociales y en su orientación hacia un determinado tipo de sujeto para recuperar una eficacia en declive.

Authors: Moyetta Daniela Silvia , Negrelli Fabián
Published: June 2023

A topic of debate in English for Academic Purposes reading comprehension courses in Spanish speaking universities is the roleof grammar in in-house materials. This study explored and analysed the way in which these materials deal with contrastive grammar, in order to promote reflection and discussion on the subject of English-Spanish contrastive grammar explanations. Results showed that there are inaccuracies in the metalanguage used, in the Spanish-English contrastive analysis of some morphosyntactic structures and in the choices of instances of direct translation from English into Spanish. It is concluded that Spanish teachers of English academic reading comprehension should be provided with reference materials that allow them to describe in a well-founded manner the differences and similarities between the linguistic resources used in these two languages.

Authors: Torres-Hergueta Enrique
Published: June 2023

Language teaching models are constantly changing. From learning based on a system of in-class, repetitive, grammar-oriented activities, we have moved to ubiquitous learning (u-learning), where the resources and tools used gain importance compared to elements such as time and space.In this scenario, TV series with integrated subtitles appear as a resource to improve listening, speaking and vocabulary skills among Spanish students of English as a Second Language (ESL). The main objective of this article is to present a case study that includes watching TV series as a continuous activity outside the classroom to motivate university students to achieve a real improvement in listening, speaking and vocabulary skills.This gives an additional boost to students’ language competences and introduces an extra motivation factor for them tocontinue using English outside the academic environment.

Does Imported Input Affect Export Quality? Case of Indonesia in The Period of 2010-2015
Authors: Tiura Herlinda  , Kiki Verico
Published: June 2023

This study aims to find empirical evidence of whether importing input as an external source of knowledge and technology transfer for developing countries affects export quality. Empirical data shows that over 75 percent of Indonesia's total import values are intermediate products used in the manufacturing process. This study combines custom data with a dataset of Indonesia’s Firm-Level data of the Large and Medium Manufacturing Industry from 2010 to 2015. It applies the fixed-effect regression method and finds that imported input has a less significant effect on the export quality. Given its numerous populations, this study indicates that increasing imported input aims to meet Indonesian domestic demand instead of export quality.

The Impact of Climate Change on Food Insecurity in The Southern African Development Community
Authors: Mavodyo Elisha
Published: June 2023

Despite the fact that the Southern African region is one of the most vulnerable to climate change, research on the impact of climate change on food insecurity in the SADC region as a whole is scarce. We make two major contributions to the literature. First, we examine how climate change affects a group of SADC countries. Second, in contrast to previous studies, we supplement an analysis of climate change on crop yield with an analysis of climate change on other food insecurity indicators such as food affordability, malnutrition, and a food insecurity measure. Relying on the system generalized method of moments (GMM) estimator, results show that precipitation has a statistically significant impact on all four indicators of food insecurity in both its linear and non-linear forms; precipitation has the greatest impact on food affordability, followed by its negative impact on malnutrition; and temperature -whether in its linear or nonlinear form- has no statistically significant influence on all four indicators of food insecurity. However, temperature change gains statistical significance in explaining movements in food security after controlling for the interaction of temperature and precipitation. The policy implications of these findings highlight the need to increase precipitation availability in the SADC region by designing sustainable irrigation programs while also implementing climate change mitigation initiatives alongside those designed to ensure food affordability and access to a healthy and decent meal, particularly for the poor.
Does Financial Development Alleviate Poverty? Empirical Evidence from Indonesia
Authors: Wardana Wahyu Wisnu , Diwanegara Rosa , Prisandy Rezza F. , Aminin  , Rohim Abdul
Published: June 2023

This study examines the contribution of financial development to poverty reduction in Indonesia using the autoregressive distributed lag (ARDL) bound testing approach to the cointegration framework. It also employs annual data of several financial development measures such as domestic credit, broad money, and financial development indexes from 1986 to 2018. Our findings suggest that financial development and poverty reduction have a cointegration relationship, regardless of the financial development indicators used. Furthermore, we find that domestic credit, broad money, financial institution depth, financial market depth, financial market access, and financial market efficiency reduced poverty. It suggests that financial development reduced poverty through its indirect channel, i.e., the economic growth effect.

Common variable immunodeficiency (CVID) is the most common symptomatic immunodeficiency in adults. This study assessed the utility of using the C-reactive protein (CRP)/albumin ratio (CAR) at diagnosis to predict mortality in CVID patients. Between 2010 and 2022, hospital records and follow-up cards of patients with CVID were reviewed retrospectively. Seventy-five patients were included in the study. CRP 0–5 mg/L and albumin 3.5–5.5 g/dL were taken as references. The CAR was obtained by dividing the CRP value by the albumin value. Of the included patients, 41 (55%) were male and 34 (35%) were female. The median age was 38 (21–77) years. The mortality rate of the patients during the follow-up time was 20%. Of the patients, 41% had splenomegaly, 10.6% had malignancy, and 39% had bronchiectasis. The cut-off value of CAR to predict mortality was >2.18 (sensitivity: 88.4%, specificity: 90.1%). When the patients were classified according to the CAR, the mortality rate in the patient group with a CAR > 2.18 was statistically significantly higher than the patient group with a CAR ≤ 2.18. The CAR is a cheap, simple, and easily calculated parameter that can predict mortality in CVID patients.
SITUATION ANALYSIS OF ELECTRIC TRANSPORT DEVELOPMENT PROSPECTS AND ITS INTEGRATION INTO UKRAINIAN POWER SYSTEM
Authors: Kostenko Kostenko
Published: June 2023

An analysis of the prospects for the development of electric transport and its integration into the energy system in the conditions of Ukraine was carried out using strategic planning methods. It was found that the transport sector in Ukraine has a significant impact on the environment, is one of the most energy-consuming sectors of the economy, and, in addition, transport with internal combustion engines is a significant factor in increasing dependence on imported fuel due to a steady and significant demand for petroleum products. Instead, it is electric transport and technologies for its interaction with the power system that are one of the key technologies that offer great potential for mitigating the effects of climate change. Thus, at the current stage, there is an urgent need to develop a stable policy of promoting these technologies, for which it is necessary to determine and compare the features of the policy of integration of electric vehicles and the energy system in the conditions of Ukraine. This study uses a qualitative strategic planning methodology using a Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis to take into account as much as possible the multifaceted activities and initiatives related to the development of electric transport and its infrastructure while integrating them into the power system. The research conducted reveals problems related to the impact of electric vehicle charging on the power system, for example, the inability to provide for increased energy needs or to limit the electrical load of the electric vehicle charging infrastructure. On the other hand, a high percentage of the share of RES, increasing social awareness of climate change and lowering the prices of electric vehicles can provide the necessary opportunities for the development of electric transport in the conditions of Ukraine.
SYSTEM OF PHYSICAL PROTECTION DURING TRANSPORTATION OF SOURCES OF IONIZING RADIATION OF THE FIRST CATEGORY
Authors: Ostapenko Ivan , Leichenko Dmitriy
Published: June 2023

The discovery of radioactivity by Antoine Henri Becquerel in 1896 was a major achievement. Today, radioactive substances are used in medicine, agriculture, heavy industry, and power generation. But while radioactivity has a wide range of useful applications, this discovery also has a flip side - the misuse of ionizing radiation that can lead to burns, radiation sickness, death, cancer, tumors and genetic mutations. A source of ionizing radiation (IRS) is a physical object containing radioactive material or a technical installation that generates or is capable of generating ionizing radiation under certain conditions. In order to ensure compliance with the permissible limits of radiation exposure of people, the population and the natural environment, as specified in codes, rules and safety standards, there is a national regulatory body. In Ukraine, since 2007, state registration of sources of ionizing radiation has been a part of licensing activities in the field of nuclear energy use. Those radioactive sources that are not or have never been under regulatory control, or are left unattended, lost, misplaced, diverted without proper government authorization, or stolen, are called "abandoned sources." The problem with "abandoned sources" is their potential danger to public health and the difficulty of detection. As a rule, sources of ionizing radiation are located in metal containers with thick walls, which makes it difficult to identify the presence of a radioactive source inside with the help of appropriate equipment. Furthermore, they are objects of different shapes and sizes, and as such they are often objects of interest to different groups of people with different purposes. Getting an "abandoned source" into the hands of ordinary citizens can have catastrophic consequences. An example of a similar situation is the radioactive contamination of the Brazilian city of Goiânia in 1987. After the theft, the perpetrators dumped radiation therapy equipment components containing the radioactive isotope cesium-137 into the trash. Later, this source was discovered by a local resident, whose actions and careless handling led to the spread of radioactive contamination, as a result of which four people died from radioactive contamination, and the area where this source is located is not suitable for life. the next 300 years.
MODELING AND ANALYZING THE EFFECT OF CONNECTION TO THE NETWORK OF A HARMONIC SOURCE HAVING VARIOUS TOTAL HARMONIC DISTORTION FACTORS ON LOAD SIGNAL WAVEFORMS
Authors: Peretyatko J.V. , Trotsenko Y.O , Polishchuk N.O.
Published: June 2023

This article examines the effect of a network connected source of harmonics having a total harmonic distortion factor varying from 5% to 15% on load voltage and current waveforms. When a source of higher harmonics is connected to the network, both in the network and in the load, the effective values of voltage and current increase, that can negatively affect the cable line insulation, accelerating its destruction and aging.

To analyze the consequences of a power quality deterioration, a 20 kV network was simulated, consisting of a 20 kV symmetrical generator, an XRUHAKXS-20(1x120/50) power cable line 20 km long, a step-down transformer 20/0.4 kV with a power of 2 MVA, with windings connected in delta-star, and a three-phase symmetrical load.

The values of the currents flowing through the cable conductor, obtained as the result of simulation were used to calculate the voltage drop between the cable conductor and its shield. Results obtained show that the connection of a harmonic distortion source to a network leads to a magnification of a current flowing through the cable conductor by more than 2%. The model proposed in the article can be used further for a more detailed study of solar photovoltaic plants connection to the grid.

One of the biggest problems regarding solar power plants is that its electricity generation is intermittent. Thus, future efforts should be focused on modeling and studying the higher harmonics generation during switching on and off of the solar photovoltaic plants.

Authors: Pukhovyi I. , Nazarova I.
Published: June 2023

The use of the effect of increasing the volume of ice when freezing water to compress the air in a tank partially filled with water is considered. The aim of the study is to create conditions for the movement of the ice surface and determine the final air pressure after freezing water. A method of air compression has been developed and theoretical and experimental studies of the final air pressure have been performed. Experimental tests of a patented method of air compression with the provision of a movable ice surface by applying thermal insulation to the air chamber at the top of the tank were carried out. For this purpose, two air compressors of different sizes are made using cold air and a mixture of ice and salt.  Obtained excess air pressures from 0.3 to 0.5 bar. The thermodynamic analysis of the process is carried out. The equation for determining the pressure at complete freezing of water, with a constant cross-section of the air compressor is obtained. Compression calculations are close to experimental data. Studies have shown the real technical possibility of air compression when water freezes in a rigid sealed tank and its use for automatic drainage of water from solar panels at the onset of frost. 1. The proposed and experimentally investigated method of ensuring the movement of the ice surface relative to the walls of the tank when compression of the air in the tank, by thermal insulation of the airspace.  Obtained thermodynamic analysis of the equation for the final pressure of the air compressed by ice. When using a tank with a constant horizontal section, the final pressure does not depend on the area of ​​the cross section and increases with increasing water level. The experiments on two installations showed that excess pressure reaches 0.3 - 0.5 bar. Freezing water tank is proposed to be used as a temperature sensor, and compressed air can drive a direct action valve. Calculations of water freezing time for compression of the air showed its significant reduction with the growth of the tank coefficient.

Background  Due to the war, the medium voltage networks are in an extremely difficult condition, they have a high degree of depreciation of electrical equipment and a low level of automation. The energy system of Ukraine has a problem of modernizing medium voltage networks and transfer them to a new class of rated voltage of 20 kV.

Objective  Overall overview of 20 kV networks and organization of their topology with renewable energy sources and " energy storages ".

Methods A network model in the MatLab software package was used to study "energy accumulators". The study of the efficiency of the "energy storages" was carried out in the variability of the power to the total load, as well as the time of connection to the network.

Results  The need to transfer voltages of 6 (10) kV to a higher level of 20 kV has been proven. Various methods of grounding the neutral of medium voltage networks are considered and the most effective modes of neutral grounding for 20 kV networks are determined: through an arc suppression coil or through a resistor. A comparative analysis of networks with and without energy storage was carried out. In 20 kV networks, without the use of energy storage, energy consumption from the network and power losses will increase. When using storage devices, they are permanently connected to the network and have their own power losses. Batteries connected to a 20 kV network lead to an oscillating process that has a damping character (within 2 seconds).

Conclusions The transition from the voltage level of 6 (10) kV to 20 kV will significantly increase the efficiency of distribution networks and reduce electricity losses. The installation of energy storage in 20 kV distribution networks will allow the introduction of new intelligent systems to ensure the interests of safety, economy and energy efficiency and will create the prerequisites for the implementation of the Smart Grid concept.

In this work, we compiled our research on lanthanide-based luminescent materials, prepared down-shifter layers, and studied their effect on photovoltaic (PV) mini-modules. The compounds we have prepared (C1-C17), with formulas [Eu2(phen)2(bz)6] (C1), [Eu2(bphen)2(bz)6] (C2), [Eu(tta)3bphen] (C3), [Eu(bta)3pyz-phen] (C4), [Eu(tta)3pyz-phen] (C5), [Eu(bta)3me-phen] (C6), [Er(bta)3me-phen] (C7), [Yb(bta)3me-phen] (C8), [Gd(bta)3me-phen] (C9), [Yb(bta)3pyz-phen] (C10), [Er(tta)3pyz-phen] (C11), [Eu2(bz)4(tta)2(phen)2] (C12), [Gd2(bz)4(tta)2(phen)2] (C13), [EuTb(bz)4(tta)2(phen)2] (C14), [EuGd(bz)4(tta)2(phen)2] (C15), [Eu1.2Gd0.8(bz)4(tta)2(phen)2] (C16) and [Eu1.6Gd0.4(bz)4(tta)2(phen)2] (C17), can be grouped into three families based on their composition: Series C1–6 were synthesized using Eu3+ ions and phenanthroline derivatives as the neutral ligands, and fluorinated β-diketonates as the anionic ligands. Complexes C7–11 were prepared with ligands similar to those of compounds C1–6 but were synthesized with Er3+, Yb3+, or Gd3+ ions. Series C12–17 exhibit the general formula [M1M2(bz)4(tta)2(phen)2], where M1 and M2 can be Eu3+, Gd3+, or Tb3+ ions, and the ligands are benzoate (bz–), 2-thenoyltrifluoroacetone (tta–) and 1,10–phenanthroline (phen). All compounds were characterized using X-ray techniques, and their photoluminescent properties were studied. We then examined their impact on the EQE (External Quantum Efficiency) of PV mini-modules and their durability in a climate chamber when embedded in PMMA and EVA films. This review emphasizes the methodology employed and the key findings, including enhanced mini-module efficiency. Additionally, we present promising results on the application of compound C6 in a bifacial solar cell.

Ribosomal proteins (RPs) mediate protein synthesis and stability of the ribosomal complex. RPs and rRNA form ribosomal subunits and ri-bosomes, the cellular machinery for protein synthesis, a fundamental biological process related to cell growth and proliferation. The differ-ences between paralogs within the same RP family have led them to ac-quire extraribosomal functions involved in plants' growth, develop-ment, and biotic and abiotic stresses. From transcriptomic analysis, it has been revealed that ribosomal proteins have a crucial role during MTs development. The RPLs; RPL11, RPL29 and RPL40 interact with PEBP family members (Phosphatidylethanolamine-binding proteins), poten-tial activators in the MTs development. In potatoes, genome editing is a promising technology to introduce crop breeding traits. Recently, the edition of the genome through the CRISPR/Cas9 system has made it the most efficient and powerful genetic modification method. Based on this, the gene modulation by overexpression and silencing in RPL11, RPL29 and RPL40 will guide us to understand the effect on the microtuberiza-tion process and produce improved potato plants with the capability of growing under adverse environments (biotic and abiotic stresses). By understanding the molecular biology mechanisms that RPs govern, we can improve crops under today's changing climatic conditions.

In current work, we illustrate the effect of adding small amount of Carbon to very common Co2MnSi Heusler alloy based-glass coated microwires. A significant change in the magnetic and structure structural properties has observed for the new alloy Co2MnSiC compared to the Co2MnSi alloy. The magneto-structural investigations have performed to clarify the main phys-ical parameters i.e., structural & magnetic at a wide range of measuring temperature. The XRD analysis illustrated the well-defined crystalline structure with average grain size (Dg = 29.16 nm) and a uniform cubic structure with A2-type compared to the mixed L21 and B2 cubic structures for Co2MnSi-based glass coated microwires. The magnetic behaviour has investigated at a tem-perature range (5 to 300 K) and an external applied magnetic field (50 Oe to 20 kOe). The adding of small amount of Carbon to the Co2MnSi matrix enhance the magnetic thermal stability, where the thermomagnetic behaviour of Co2MnSiC glass-coated microwires show a perfect stable be-haviour for a temperature range from 300 K to 5 k, the differences between the coercivity value is only 0.3 Oe compared to 4 Oe for Co2MnSi-sample. In addition, M-H loops measured at tempera-ture below 50 K show unsaturated loops; meanwhile the Co2MnSi loops shows a strong antifer-romagnetic coupling for the loops measured below 50 K. By studying the field cooling (FC) and field heating (FH) magnetizations curves at a wide range of external applied magnetic field we detected a critical magnetic field (H = 1 kOe) where FC and FH curves have a stable magnetic behavior for Co2MnSiC sample, such stability does not find in Co2MnSi sample. We proposed a phenomenal expression to estimate the magnetization thermal stability, ΔM (%), of FC and FH magnetization curves and the maximum value is detected at the critical magnetic field where ΔM (%) ≈ 98 %. The promising magnetic stability of Co2MnSiC glass-coated microwires with tem-perature is due to the changing of the microstructure induced by adding Carbon, as the A2-type structure show a unique stability by variation the temperature and the external magnetic field. In addition, a unique internal mechanical stress, which induced during the fabrication process and plays on controlling magnetic behavior with temperature and external magnetic field. The ob-tained results make Co2MnSiC promising candidate for magnetic sensing devices based Heusler glass-coated microwires.

Published: June 2023

Pars plana vitrectomy is today a common first-line procedure for treatment of rhegma-togenous retinal detachment (RRD). Removal or preservation of the natural lens at the time of vitrectomy is associated with both advantages and disadvantages. The combi-nation of cataract extraction (i.e., phacoemulsification) with pars plana vitrectomy (PPVc) enhances visualization of the peripheral retina and the surgical management of the vitreous base. However, PPVc prolongs the surgical time and is associated with iatrogenic loss of the accommodation function in younger patients, possible postoperative aniso-metropia, and unexpected refractive results. Performance of pars plana vitrectomy alone (PPVa) requires good technical skills to minimize the risk of lens damage, and quickens cataract development. We retrieved all recent papers that directly compared PPVc and PPVa using parameters that we consider essential when choosing between the two procedures (the success rate of anatomical RRD repair, postoperative refractive error, intra and postoperative complications, and costs). PPVa and PPVc were generally comparable in terms of RRD anatomical repair. PPVc was associated with fewer intraoperative, but more postoperative, complications. Macula-off RRD PPVc treatment was often associated with undesirable myopic refractive error. PPVa followed by phacoemulsification was the most expensive procedure.

Papillary thyroid cancer (PTC) is commonly characterized by multifocality, which is associated with aggressive features and a less favorable prognosis. The current study aimed to compare the clinicopathologic characteristics and long-term oncological outcomes of bilateral and unilateral multifocal PTC. The medical records of 1745 patients with multifocal PTC who underwent thyroid surgery at Seoul St. Mary’s Hospital were retrospectively reviewed. The clinicopathological characteristics and recurrence rates were compared based on cancer laterality. Further, 357 patients who underwent total thyroidectomy were matched to investigate the recurrence risk and disease-free survival (DFS). Before propensity score matching (PSM), there was no significant difference in the recurrence rate between the bilateral and unilateral multifocal PTC groups. Cancer laterality was not a predictor of DFS based on the Cox regression analyses. However, after PSM, unilateral multifocality was associated with a significantly high risk of recurrence. Similarly, unilateral multifocality was associated with a significantly poor DFS based on the Kaplan–Meier analysis. Compared with bilateral PTC, unilateral multifocal PTC was associated with a poor DFS. A comprehensive preoperative examination should be performed to detect multifocality before the initial surgical intervention for optimal treatment. Postoperative short-term follow-up is recommended for unilateral multifocal PTC for recurrence surveillance.
