Published: February 2023

The orbit of BeiDou satellite system is a very ideal space environment monitoring area. The radiation dosimeters are present on this series of navigation satellites, and they are respectively installed in the x, y and z positions. A charge detector installed in the satellite cabin is used for monitoring satellite deep charging potential. Radiation dosimeters select the 100 nm P-channel metal oxide semiconductor (PMOS) sensors, whose monitoring range can reach 2 × 106 rad (Si). In the circuit design part, the “zero temperature coefficient” current of the PMOS is used as the constant current source for measuring, which effectively reduces the influence of temperature effect. Three radiation dosimeters realize the daily dose change monitoring during the satellite’s operation, and the detection accuracy is high. The deep charging potential sensor adopts the equivalent capacitor design which is composed of the outer optical quartz glass and the inner circular gold-plate. The two kinds of detection instruments have the characteristics of small volume, low power consumption and high detection accuracy. The detection results show that they have important application value for space environment prediction and guarantee.
The Individual Social Account as a Platform for Citizen Interaction with Government
Authors: Swanson E. Burton
Published: February 2023

In this brief paper, offered as a policy viewpoint, I introduce what I believe to be a novel concept for supporting individual citizen interaction with the U.S. Federal government, termed the individual social account. I explore whether and how the concept might be implemented so as to strengthen the U.S. social safety net and further citizen trust and responsibility in e-government interactions. I illustrate and develop the concept as a platform for reform and suggest and discuss design criteria, surfacing various issues. I conclude with additional thoughts with which to stimulate further research and discussion of the concept and its practicalities.
A More Socio-Environmentally Responsive Way to Organise the Firm? A Case Study on Danish Social Enterprise Law
Authors: Liptrap J. S.
Published: February 2023

It has been claimed that social enterprises have the capacity to counteract the negative impact that business has had on the environment, inequality and social cohesion. Yet, such claims remain largely untested – commentators have not attempted to actually apply insights from the social enterprise law context to debates within the wider field of corporate governance. A primary reason for this inconsistency is that, from a European perspective, there is a dearth of scholarship that aims to analytically model social enterprise law. This is problematic because there is not an established body of work from which commentators can draw. In turn, the scope for effectively leveraging social enterprise law within more mainstream corporate sustainability discourses is hindered. This article contributes an analytical model of Danish social enterprise law to the literature. The hope is that this case study will encourage, and equip, commentators to not only claim that social enterprise law has applicability in progressive corporate reform debates, but to also show directly how, and where, this might be so.
A New Start for the European Private Company: The Draft Statute for a “Société Européenne Simplifiée” (SES)
Authors: Verse Dirk A.
Published: February 2023

654
In February 2021, an international group of experts under the auspices of the French lawyers’ association Henri Capitant published a draft statute for a “European Simplified Company” (Société Européenne Simplifiée, SES). The draft intends no less than to revive the idea of a European Private Company (SPE), albeit in a modified manner. Unlike the SPE proposal, the SES initiative does not exclusively aim at adopting an EU regulation under Art. 352 TFEU that requires the consent of all 27 Member States. Instead, it is open for alternatives to EU-wide regulation, be it by way of enhanced cooperation under Art. 20 TEU or an international treaty between the interested Member States. In June 2021, the SES initiative gained the support of the Franco-German Parliamentary Assembly calling on the French and German governments to intensify their efforts in working towards a supra-national private company on the basis of the SES proposal.It is against this background that the present article seeks to analyse the objectives and main features of the Draft SES Statute. In the author’s view, the SES initiative should be welcomed as it seeks to fill an evident gap in the existing EU company law framework. The paper concludes that, despite several concerns that still need to be addressed, the Association Henri Capitant’s Draft SES Statute provides a solid and suitable basis for the consultations to come.

Incorporation of poly(3-acrylamidopropyl trimethylammonium chloride-co-acrylic acid) branches for good sizing properties and easy desizing from sized cotton warps
Authors: Zhang Chaohui , Li Wei , Xu Zhenzhen
Published: February 2023

This study aimed to ascertain the influence of poly(3-acrylamidopropyl trimethylammonium chloride-co-acrylic acid) [P(ATC-co-AA)] on the adhesion, film properties, desizability of cornstarch, and reveal a suitable mole percentage of ATC units on the P(ATC-co-AA) for acquiring a new starch-based size [S-g-P(ATC-co-AA)]. A series of S-g-P(ATC-co-AA) samples were synthesized by the graft polymerization of acid-converted cornstarch with ATC and AA monomers. Their adhesion, film properties, and desizability were assessed. The results displayed that the P(ATC-co-AA) branches could significantly improve the adhesion to cotton fibers and diminish the film brittleness of starch. Under similar grafting ratio, the adhesion and desizability of S-g-P(ATC-co-AA) depended on the mole percentage of ATC units. Increasing the percentage favored the adhesion but disfavored the desizability. The percentage displayed a low effect on the film properties. S-g-P(ATC-co-AA) with a mole percentage of 57.7% presented good sizing properties and easy desizing, which had potential application in cotton warp sizing.
Estimating 3D displacement vectors from line-of-sight observations with application to MIMO-SAR
Authors: Baumann-Ouyang Andreas , Butt Jemil Avers , Wieser Andreas
Published: February 2023

Displacements in typical monitoring applications occur in 3D but having sensors capable of measuring such 3D deformations with areal coverage is rare. One way could be to combine three or more line-of-sight measurements carried out from different locations at the same time and derive 3D displacement vectors. Automotive Multiple-Input-Multiple-Output Synthetic Aperture Radar (MIMO-SAR) systems are of interest for such monitoring applications as they can acquire line-of-sight displacement measurements with areal coverage and are associated with low cost and high flexibility. In this paper, we present a set of algorithms deriving 3D displacement vectors from line-of-sight displacement measurements while applying spatial and temporal least squares adjustments. We evaluated the algorithms on simulated data and tested them on experimentally acquired MIMO-SAR acquisitions. The results showed that especially spatial parametric and non-parametric least squares adjustments worked very well for typical displacements occurring in geomonitoring and structural monitoring (e.g. tilting, bending, oscillating, etc.). The simulations were confirmed by an experiment, where a corner cube was moved step-wise. The results show that acquisitions of off-the-shelf automotive-grade MIMO-SAR systems can be combined to derive 3D displacement vectors with high accuracy.
Topologically-optimized on-chip metamaterials for ultra-short-range light focusing and mode-size conversion
Authors: Ma Wei , Hou Maojing , Luo Ruiqi , Xiong Bo , Liu Nan , Liu Guandong , Chu Tao
Published: February 2023

The concept of metamaterials offers a flexible pathway to manipulate the macroscopic behavior of light by delicately designed microscopic subwavelength structures, which has been recently introduced to integrated photonics to create devices with ultra-compact footprint, excellent performance or versatile functionalities. However, the conventional design approach of metamaterials, including two separated steps of subwavelength structure design and the assembly of unit cells, often encounters challenges when facing extreme design targets. In this work, we propose a hierarchical inverse design approach by cascading a conventional unit-cell-based design with a holistic topology optimization. As a proof-of-concept, we demonstrate ultra-short-range light focusing and mode-size conversion enabled by on-chip meta-lenses. The shortening of tapering region pushes higher numerical aperture of on-chip lenses, leading to the violation of locally periodic approximation used in meta-lens design and thus poor device performance, which fortunately, can be well compensated by the follow-up holistic optimization step. We experimentally realize mode-size squeezing by almost 20 times in a tapering region as short as 8 μm and 5 μm with low insertion loss and broadband performance. The proposed design scheme provides practical guidelines to design metamaterials as flexible on-chip wavefront control and light routing devices for various applications in fiber communication, sensing and optical computing.

Authors: Madelatparvar Mahdi , Hosseini Mahdi Salami , Zhang Chunwei
Published: February 2023

The application of micro-/nano-capsules in construction industries has been rising over the past decade. Polyurea with tunable chemical and morphological structure are of interesting polymers to prepare micro-/nano-capsules used in construction. The structure of polyurea micro-/nano-capsule is capable to be tailored via bulk emulsion or microfluidic method. Important factors for production of micro/nano-capsules are the rate of fabrication and having control over mean size, dispersity, and wall thickness. The bulk emulsion method provides higher yield of production with less control over sizes and dispersity in comparison to microfluidic technique. The main applications of polyurea micro-/nano-capsules in construction industries are categorized as thermal energy saving, self-healing concrete, self-healing polymers, and fire retarding. Polyurea showed appropriate thermal conductivity and mechanical properties which is required for encapsulation of phase change materials. Titanium dioxide polyurea microcapsules possess energy storage efficiency of 77.3% and thermal storage capacity of 99.9%. Polyurea microcapsules with sodium silicate cargo provided self-healing abilities for oil well cement in high temperature and showed higher self-healing abilities compared to gelatin microcapsules. Graphene oxide polyurea micro-/nano-capsules demonstrated 62.5% anti-corrosive self-healing efficiency in epoxy coating, and steel coated via dendritic polyurea microcapsules embedded polyurethane remained unchanged after long time immersion in salt water.

Conscription Reloaded? The Debate About Compulsory Service in Germany in 2022 and the Peoples’ Attitudes Towards It
Authors: Jäckle Sebastian
Published: February 2023

In mid-2022, Federal President Frank-Walter Steinmeier spoke out in favour of introducing compulsory service in Germany. Against the backdrop of the Bundeswehr restructuring, necessitated by the war in Ukraine, and the worsening personnel shortage in the social sector and in nursing care, he revived a debate that had been recurring in Germany for decades. Based on an online survey of more than 7,300 people, this article examines how Germans feel about compulsory service and what factors are associated with this attitude. More than 63% of respondents are in favour of compulsory service. Psychological factors such as solidarity, sense of duty, extraversion and openness play just as important a role as political attitudes. People who position themselves more right-wing/nationalist/traditional view compulsory service more positively than liberal and left-wing respondents. In terms of voting intention, CDU/CSU and AfD supporters in particular support a general compulsory service, whereas it is less strongly supported by Greens, SPD and FDP supporters and even rejected by a majority of Left supporters. Another key factor for the evaluation of compulsory service is the respondents’ own experience with completed service. Respondents who have done military service view compulsory service more positively than those who have done community service. Those who have regular voluntary commitments also view compulsory service positively.
Incomplete Fermatean fuzzy preference relations and group decision-making
Authors: Şimşek Necip , Kirişci Murat
Published: February 2023

There may be cases where experts do not have in-depth knowledge of the problem to be solved in decision-making problems. In such cases, experts may fail to express their views on certain aspects of the problem, resulting in incomplete preferences, in which some preference values are not provided or are missing. In this article, we present a new model for group decision-making (GDM) methods in which experts’ preferences can be expressed as incomplete Fermatean fuzzy preference relations. This model is guided by the additive-consistency property and only uses the preference values the expert provides. An additive consistency definition characterized by a Fermatean fuzzy priority vector has been given. The additive consistency property is also used to measure the level of consistency of the information provided by the experts. The proposed additive consistency definition’s property is presented, as well as a model for obtaining missing judgments in incomplete Fermatean fuzzy preference relations. We present a method for adjusting the inconsistency for Fermatean fuzzy preference relations, a model for obtaining the priority vector, and a method for increasing the consensus degrees of Fermatean fuzzy preference relations. In addition, we present a GDM method in environments with incomplete Fermatean fuzzy preference relations. To show that our method outperforms existing GDM methods in incomplete Fermatean fuzzy preference relations environments, we have provided an example and compared it with some methods. It has been seen that our proposed GDM method is beneficial for GDM in deficient Fermatean fuzzy preference relation environments and produces meaningful results for us.
The double cluster compound [Nb6Cl14(MeCN)4][Nb6Cl14(pyz)4]·6MeCN (Me: methyl, pyz: pyrazine) with a layered structure resulting from weak intermolecular interactions
Authors: Sperlich Eric , Köckerling Martin
Published: February 2023

The synthesis and the crystal structure of the double cluster compound [Nb6Cl14(MeCN)4][Nb6Cl14(pyz)4]·6CH3CN are described. The synthesis is based on a partial ligand exchange reaction, which proceeds upon dissolving [Nb6Cl14(pyz)4]·2CH2Cl2 in acetonitrile. The compound is built up of two discrete neutral cluster units, which consist of octahedra of Nb6 atoms coordinated by 12 edge-bridging chlorido and two terminal chlorido ligands, and four acetonitrile ligands on one and four pyrazine ligands on the other cluster unit. Co-crystallized acetonitrile molecules are also present. The single-crystal structure determination has revealed a cluster arrangement in which the [Nb6Cl14(pyz)4] units are connected by (halogen) lone-pair–(pyrazine) π interactions. These lead to chains of [Nb6Cl14(pyz)4] clusters. These chains are further connected to cluster layers by (nitrile-halogen) dipole–dipole interactions, in which the [Nb6Cl14(MeCN)4] and co-crystallized MeCN molecules are also involved. These cluster layers are arranged parallel to the crystallographic {011} plane.
Developing Patient-Centered Preventative Care to Reduce Mobility Disability With Aging: Preferences From a Discrete Choice Experiment
Authors: Lieberz Dalerie , Bishop Toni , Rohde Mary , Schmidt Aaron , Schmitz Olivia , Moffett Marilyn , Borstad Alexandra
Published: February 2023

Background and Purpose:

Mobility disability is the most prevalent form of disability for older adults in the United States. A physical therapy mobility checkup (MC) under development is a patient-centered preventative physical therapy visit. It includes physical performance testing and education on physical performance as a valuable and modifiable health indicator. The purpose of this study was to identify the proportion of older adults willing to participate in an MC, the age at which they would initiate care, their desired frequency of participation, and the characteristics, or attributes, of the MC they preferred.

Methods:

In a cross-sectional study conducted at the Minnesota State Fair, adults older than 55 years answered survey questions about preventative health practices and completed a discrete choice experiment (DCE) to determine their preferences for the MC. Attributes studied in the DCE were visit duration, checkup content, education, and possible outcomes of participating in preventative care for mobility. Descriptive statistics characterized demographic information and survey responses. Conjoint choice modeling estimated the main effect for each DCE attribute.

Results and Discussion:

One hundred sixty-six older adults participated in the study. Seventy-eight percent indicated that they would choose an MC if available. Most participants (66%) believed that MCs should occur before 60 years of age and at least annually (68%). A 30-minute visit duration, which accounted for 84% of attribute importance, was preferred. Balance, the preferred content of the MC, accounted for 12% of the attribute importance. Preferences for educational content and possible outcomes of participation with preventative care aimed at preventing mobility loss were not statistically significant.

Conclusion:

Older adults value preventative care for reducing mobility disability. They identified time efficiency and the inclusion of measures to assess balance as priorities for this preventative physical therapy visit.

Zinc sulphides/reduced graphene oxide nanocomposites were prepared through a sonochemical route. As grown zinc sulfide nanoparticles were added with different ratios in ethanolic solution of reduced graphene oxide. The mixture were ultrasonicated for 2h and then kept for aging. The obtained samples were characterized by optical transmission, FTIR, luminescence, structural and morphological characterizations. On addition of ZnS nanoparticles the shift in luminiscence peak is observed towards higher wavelength. A small peak is obtained at 440nm to 450nm which might be due to electron tapping in band gap region. Sharp luminescenct peak in UV region is observed for higher addition of ZnS.

Water pollution problems by dyes is one of the dangerous pests facing the environment, especially those dyes that cause health problems. In this study, CdO-MnO2 Nanocomposite have been successfully synthesized by simple chemical method. The crystallite size and morphology of the Nano-synthesized powders were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The SEM result revealed that, the average particle sizes was 31.56 nm with particles shape as a Zero dimension. The CdO-MnO2 Nano-synthesized behave as an attractive adsorbent for Methylene orange (M.O) dye in aqueous solution by various temperature (25, 35, 45 and 55˚C). The thermodynamic parameters (ΔS, ΔH, ΔG) and Kinetic (order of the adsorption process) were calculated. The results show that the application of nanocomposite CdOMnO2 would be promoted by high adsorption capability and selectivity for dye solutions (M.O). CdO-MnO2 can considered as a friend of the environment and Nano powder as advanced adsorbent materials.

This paper reports the role of biological template on the performance of dye-sensitized solar cells (DSSC) fabricated using tinoxide (SnO2) nanoparticles. Herein, onion (Allium cepa) has been employed as the biological template in the synthesis of tin oxide nanoparticles for the first time and is compared with SnO2 prepared without the template. The prepared samples were systematically characterised using the state-of –the art facilities. A sandwich cell was prepared by using the dye soaked SnO2 film acting as the photoanodeand platinum coated on FTO as the counter electrode with I3 ¯ /I ¯ as the electrolyte. Current-voltage (I-V) characteristics have been studied using solar simulator. Performance of DSSC prepared with and without the template is analysed from the measured I-V curves and it is observed that the DSSC prepared using the biotemplate shows better efficiency (9.54%) and fill factor (0.5352).

The sensing properties of two chalcogenide materials were investigated. It is shown that membranes based on the PbI2-Ag2S-As2S3 and PbS-Ag2S-As2S3 materials show sensitivity to the presence of Pb2+ species in solution. In both cases they exhibit near-Nernstian response. We mainly focused on the best matrix. The basic physicochemical parameters were then measured. The developed ISE exhibits a near-Nernstian slope of 27 mV/decade versus Pb2+ in the range of 10−5,5 - 10−3 M. Moreover the proposed Pb-SE shows excellent out-put signal in the presence of foreign ions. The analytical properties such as reproducibility, response time, and stability were studied. We report a multi-sensor process that we developed for in-situ real-time monitoring of waste water. The very first results of prototype measurements are presented.

We present the structural, optical, electrochemical, and photocatalytic studies of octadecyl amine capped CdS quantum dots (ODA-CdS). TEM micrographs showed CdS quantum dots with particle sizes of 1.9-5.2 nm. The optical bandgaps of the quantum dots are 2.03, 2.06 and 2.01 eV for ODA-CdS1, ODA-CdS2 and ODA-CdS3 respectively, which was less than the bandgap of the bulk CdS (2.42 eV). Photo-electrochemical band gaps of 2.60 V for ODA-CdS1, 2.24 V for ODA-CdS2 and 2.46 V for ODA-CdS3 were obtained from cyclic voltammetry. The photocatalytic degradation efficiency of methylene blue was 62% for ODA-CdS1, 80% for ODA-CdS2, 69% for ODA-CdS3.

Silver doped cadmium sulphide thin films were deposited on a polyethylene terephthalate flexible substrate through the chemical bath deposition method varying the silver deposition time. In this study we analyzed the absorbance in the visible range between 430 and 800 nm. The direct band gap was calculated with the Tauc method, yielding values of 2.25 to 2.46 eV. The crystallographic structure was determined by X-ray diffraction. An evolution was observed from the original hexagonal cadmium sulphide pattern to the appearance of characteristic signals of metallic silver. Scanning electron micrographs were obtained to describe the morphology of the films’s surface. Finally, the electric resistivities measured were in the range of 5.0 and 12.1 x 107 Ω cm.

Self-assembled nanorods/nanowires of CdS were successfully synthesized by a solvothermal method at 200 oC for 5, 10 and 20 h using sodium dodecylsulfonate as a capping reagent. X-ray diffraction (XRD) patterns of all CdS samples can be indexed to pure phase of hexagonal CdS structure. The degree of crystallinity of CdS was increased with the increase of holding reaction time from 5 h to 20 h. Transmission electron microscopic (TEM) images revealed that the product synthesized by the solvothermal method at 200 oC for 20 h contained self-assembled flower-like CdS nanostructure. The UV-visible absorption of self-assembled flower-like CdS nanostructure shows excellent absorption in UV-visible region with the absorption peak at 481 nm. Photocatalytic efficiency of the as-prepared CdS samples was investigated through rhodamine B (RhB) degradation under visible light irradiation. In this research, the self-assembled flowerlike CdS nanostructure has the highest degradation of 94.91 % within 80 min.

CdSe capped with Tri sodium citrate (TSC), nanoparticles were organized by chemical process at ambient conditions. Spin casting technique was used to deposit thin films on substrates from glass at room temperature. Schottky junctions have been fabricated by depositing CdSe thin films using the spin coating on Aluminum (Al) and Florien Tin Oxide (FTO) coated glass substrates and their properties have been investigated by current–voltage measurements. The characteristics obey the pure thermionic emission theory and the contact showed a good rectifying behavior in both structures.

The Nd3+ doped yttrium lead borotellurite glasses with the chemical composition (49- x)H3BO3-35TeO2-15PbO-1.0Y2O3-xNd2O3 (x = 0.0, 0.5, 1.0, 1.5, 2.0, and 2.5 mol%) were successfully synthesised by using melt-quenching technique. The amorphous nature of all the glass samples were confirmed through the XRD spectra and various structural parameter were determined. The ultrasonic velocities and elastic moduli were measured from the measured density and ultrasonic velocities. From the analysis, it indicates that the physical properties of these glasses depend upon the role of Nd2O3 content inside the glass system and the compositional changes of the glass system.

This Work represents the influence of some parameters (Temperature, existence of Buffer layer and its thickness), using a Numerical simulation of thin film solar cells, named SCAPS (which is a one-dimensional solar cell capacitance simulator) in modeling of the high efficiency CIGS-based solar cells (with efficiency of η=10.87%).In each case, the photovoltaic parameters have been calculated. It has been concluded that, the efficiency of CIGS-based solar cells is decreasing with increasing of the temperature and the thickness of Zinc Sulfide buffer layer. However, when the buffer layer doesn’t exist in solar cells photovoltaic, we noticed that the efficiency of solar cells is increasing to (η=12.04%) under the AM1.5 spectrum, one sun and at room temperature, with increasing of the short-circuit current density (Jsc), and decreasing of open-circuit voltage (Vco).

El retrato de Tomás Moro por Herrera
Authors: Rallo Gruss Asunción
Published: February 2023

El Tomás Moro de Herrera es un retrato singular. Difícil de clasificar genéricamente, han sido varias las propuestas: biografía ejemplar, panegírico, memorabile. Se ha insistido en la abundante presencia de moralización y en la aplicación de ideas sacadas de las Institutio Principis Christiani. Este artículo rastrea y estudia los elementos propios de un retrato. Se detiene en la utilización de la contrafigura del rey Enrique VIII para la modelación del retrato. Traza el significado de la virtud en sus abundantes y variadas apariciones en la obra. Finalmente se interesa por los motivos que implican su escritura y publicación.
Las máscaras del monstruo: representaciones e imaginarios en el "noir" gallego
Authors: Núñez Sabarís Xaquín , Ribeiro Eunice
Published: February 2023

Este trabajo tiene por finalidad analizar la representación del monstruo y su materialización en narrativas (literarias y fílmicas) contemporáneas. Se partirá de las aproximaciones teóricas acerca de la figura del monstruo en las sociedades occidentales, desde un punto de vista filosófico y literario. En el contexto de las obras seleccionadas juega también un papel importante la máscara, ya sea explícita, ya metafórica, como una ocultación o revelación de la identidad, imprescindible para la intriga que se crea en la narrativa de suspense. Se analizarán, consecuentemente, creaciones literarias y audiovisuales, ambientados en Galicia y/o de creación gallega. Esta circunstancia permitirá abordar, como hipótesis de trabajo, la incidencia del factor espacial, cultural y etnográfico, en la configuración de los relatos, y, consecuentemente, su contribución a la caracterización de terror, esotérica, o mítico-mágicas de las diferentes narraciones estudiadas.
Importance of nutrigenomics and nutrigenetics in food Science
Authors: Uthpala TGG , Fernando HN , Thibbotuwawa Amila , Jayasinghe M
Published: February 2023

Nutrigenomics and nutrigenetics are bidirectional terms that are interrelated as two sides of a coin. Nutritional genomics is the latest scientific discipline that uses modern genomics technology to study the relationship between genes, nutrition, and health. It explores the effects of nutrients on the entire genetic makeup (genome), proteome, and metabolome. Simply, nutrigenomic defines how the diet acts on genes and changes gene expression which is commonly prominent in cancer like non-communicable diseases. Nutrigenetics explains how the genes affect the diet which is generally notable in illnesses like phenylketonuria and lactose intolerance. Nutritional genetics combines the study of nutrition and genetics to discover the different ways people respond to food based on their genetic makeup. Even though humans are similar in genetics, we all have slight differences in our genetic blueprints due to single nucleotide polymorphisms (SNPs) that make us unique from each other. These tiny variations determine both the effect nutrients have on our bodies and how we metabolize the food that we eat. Personalized nutrition connects this two-way relationship between nutrients and genes. This mini-review discusses the applications, advantages, and disadvantages, Sri Lankan context, and future trends of these emerging technologies. Furthermore, this review emphasizes how the consumed nutrients can affect our gene expressions as well as how our genes can influence response to these nutrients. This emerging field could be improved to enhance personalized diet consumption trends depending on individual genetic makeup and to develop innovative functional foods based on genetic patterns. Finally, the production of biomarkers could be applied in the future to predict early disease recognition and to mitigate disease risk.
The place of doctors in the service market system of Byzantium of the IV–IX centuries.
Authors:   V. N. Karazin Kharkiv National University, Sorochan Serhii
Published: February 2023

The article analyzes the position and status of medical and pharmaceutical staff in the Byzantine labor market and services. Their place in society and in the professional sphere is considered equal in essence and quality to that of the craftsmen — vanavsos. It is emphasized that in most cases they did not belong to slaves, as it was in the ancient Roman society, but to free, wealthy strata of the population, to those who were classified as euporus, endesters with an annual income of at least 25–50 solidi, and their salary allowed them to provide themselves with everything they needed. Paid visit to the doctor, iatraros was considered as a daily routine. Sometimes it took place at public cost, mainly in the capital of the Roman Empire in the early Byzantine period, but also among monks. Getting into the ranks of medical professionals was limited only by the financial solvency of those who studied this craft, unless, of course, it was inherited from father to son. In the Byzantine Empire in the IV–IX centuries, medical services were provided both in private, paid, and at the state, public levels.

Authors:   Taras Shevchenko National University of Kyiv, Kuryliak V.V.
Published: February 2023

The relevance of the study is due to the current active functioning of religious chapels at medical institutions, in particular, in Ukraine. Against the background of such tendentiousness, the attention of scientists is attracted by the features of the integration of religious practices into the processes of interaction with traditional medicine. In the course of the study, the origins of the beginning of the work of hospital chapels in Ukraine are analyzed, starting with samples such as a stone hospital for veterans in the Lviv region of the 17th century, in parallel with modern examples. In the course of the study, the processes of the emergence of the most famous hospital chapels in Lviv, Kharkov, Odessa, Nikolaev and Kyiv regions were considered. For objectivity, photographs of the first Murovany Hospital for Veterans (XVII century), the Alexander Hospital and the Mikhailovskaya Church attached to it (1901), the Mikhailovskaya Church at the beginning of the 20th century, compared with its current state are given. The history of the beginning of more than ten religious chapels at hospitals is analyzed. The connection between the programmed goals of the beginning of the chapels and their current mission and functionality is determined. The history of the creation and sustainable functioning of hospital religious chapels in Ukraine is viewed through the prism, against the background of the functioning of architectural objects, mutual tolerance and reasonable interaction between medical institutions and religious denominations. An analysis of the stated problems will allow a better understanding of the features of the current functioning of hospital chapels. The characteristics of the stated issues will help to expand the understanding of the features of the interaction between religion and medicine in modern times.
