IRON AGRICULTURAL TOOLS FROM REVNE
Authors: Gorbanenko S. A. , Mykhailyna L. P.
Published: November 2021

Iron agricultural tools from the Revne agglomeration of Slavs of the 8th—10th centuries is analyzed in the paper. The complex is one of the outstanding sites of the Eastern Croats Slavic tribal group in the Ukrainian Carpathian region (fig. 1). During ca. 50 years of stationary and supervisory explorations almost complete set of agricultural tools for primary and secondary tillage and for harvesting has been accumulated.
The paper provides detailed description of the tools. Comparative analysis of the materials in geographical environment was carried out both in the area of Raiky culture and synchronous and chronologically close cultures and sites. Iron parts of plow-type tools certify a high level of technical equipment for tillage. Asymmetrical heads are inherent in bow ard. This plow-type tool had the head with iron wide-bladed tip posed horizontally to the ground and also knife coulter and mouldboard. Arable tools of this type cutted and turned the soil. Their use indicates the highest level of development of technical capabilities of tillage in the area of Raiky culture and synchronous archaeological cultures (fig. 2—4, 9). Hoes of two types are presented: the socketed items with a vertical open socket and those with a horizontal solid socket. Both types are well-known (the first type is much more common) but functionally there is no difference between them. Their analogies are common in the area of Raiky culture and synchronous surrounding (fig. 5, 6, 9).
The harvesting process can be considered traditional for the people of Raiky culture. However there are insignificant differences comparing to the aggregate data. Thus, scythes with a curved handle (mainly used for haymaking and possibly for harvesting cereals with a tight ear) have not yet been occurred in Revne. However, such findings are generally much less common than sickles (fig. 7—9).
The complex of iron agricultural tools shows the highest level of development of agriculture in the people of Raiky culture. Comparative analysis with other cultural and ethnic groups of the late 1st millennium AD in Central and Eastern Europe also shows that the level of agriculture is close to the achievements of the Saltiv culture.
BURIED FURROWS OF MEDIEVAL ARABLE IMPLEMENTS IN CHERNIHIV
Authors: Chernenko O. Ye.
Published: November 2021

Evidence of ancient plowing systems known in Scandinavia, Denmark, Italy and Poland was found in North-western Rus on the Rurik hill-fort and Novgorod. Almost always they were dated to the 9th—10th century. Evidence of several arable area, dated by the ceramics of Romny culture to the 9th—10th century, was occurred on the left bank of the Dnieper: in Prorva, near Trubchevsk (Bryansk region, Russian Federation) and Avtunichi in the Chernihiv region. A ploughed area in the northern part of the Chernihiv hill fort was recorded by V. Kovalenko in 1986. Similar traces were recorded by the author in 2005—2006 on the neighboring site at the area of more than 1,500 m2. The plough line were visible in the virgin soil as long (up to 10 m) rather narrow (from 2 to 10 cm) and deep (5—10 cm) furrows of triangular cross-section. They were filled by the light grey sandy loam with charcoal inclusions. The furrows overlapped each other perpendicularly forming the dense mesh. Individual double furrows with an internal distance of about 20 cm were also recorded. They are evidence of use of the double plough with narrow sub-triangular points. Judging by the location of the furrows the crosswise ploughing of the field was repeatedly carried out over several years. The horizon above ploughing was dated to the 10th century. This dating was based first of all on the finds of rough thick-walled Rus ceramic vessels with a slightly turned, flaring, flat rims, in combination with single fragments of handmade Romny culture ceramics and a slate spindle whorl. The presence of the plowing system directly before the appearance of settlement also challenges the frequently expressed opinion that earlier layers of the of the Chernihiv hill fort were completely destroyed by later activity. Had that been the case, the furrows would not have survived either.
THE SETTLEMENT OF VYSHENKY 1 ON DESNA RIVER
Authors: Zharov G. V. , Terpylovskyi R. V.
Published: November 2021

In 2013, the Livoberezhna Archaeological Expedition made the rescue excavations at the Vyshenky 1 settlement near the Vyshenky village Korop district of Chernihiv region. The settlement is located on the edge of the high right bank of the Desna River. In the excavation area of 120 m2 more than 20 ancient household pits, a number of post-holes and the part of building 1. In addition to some finds of the Bronze Age and Kyiv Rus the main materials date to the 1st millennium AD.
The lower horizon (building 1, pits 4, 12, 20, 21, 23) belongs to the Kyiv culture of the Late Roman period. The building was probably square semi-dwelling house with a central pillar. Pottery is represented mainly by pots of weakly profiled and ribbed forms. The flattened biconical spindle whorls with a large hole, as well as single fragments of pottery were occurred in the objects. In addition to fragments of typical Chernyakhiv pottery, the fragment of a red slip bowl of the second half of the 4th and the beginning of the 5th centuries, unique for Desna basin region, was found. Obviously, this is t the possible final date for the layer of Kyiv culture.
The upper horizon of the settlement belongs to the sites of the Sakhnivka-Volyntsevo circle. Pits 6, 17—19, 22 contained the fragments of convex-sided pots with bent rims, usually ornamented with finger impressions on the edge, and frying pans. The flattened-rounded spindle whorls and fragments of clay ovoid blocks belong to the same period.
The hand-made pottery from sites of the Sakhnivka type is practically indistinguishable from significant part of the ceramics of the Volyntsevo culture, so the pottery of different types which often occurs in complexes with the hand-made ceramics usually becomes the diagnostic sign. In Sakhnivka sites there are sometimes pottery of the Pastyrske type, and in the Volyntsevo sites dating a little later there are so-called “pots of the Volyntsevo type”. However, in the settlement of Vyshenky 1 the household pits of this horizon contained only hand-made pottery, so it is difficult to draw a final conclusion about its cultural and chronological identification.
RESIDENTIAL BUILDING OF THE FIRST HALF OF 17th century IN LUBECH
Authors: Veremeychyk O. M.
Published: November 2021

The antiquities of Lyubech of 17th—18th centuries have been known to the scientific community since the B. O. Rybakov’s excavation of the hillfort Zamkova Hora during 1957—1960. Here the powerful cultural layer and remains of buildings, including defensive ones has been recorded. Next time the dwellings and household buildings of this period were recorded by the works of A. L. Kazakov in Lyubech suburb (posad) in 1989—1990. At the beginning of the current century the archaeological expedition of the Taras Shevchenko National University “Chernihiv Collegium”, headed by the author, explored significant areas of the ancient Lyubech in three places — hillforts Zamkova Hora and Monastirishche, as well as the suburb (posad) of Lyubech near stone building (Kamianitsa) of hetman Poubotok. Just at its territory where 372 m2 have been excavated the residential and commercial buildings of the 17th—18th centuries were disco-vered.
In 2013 and 2016 the remains of rich residential building destroyed in a fire in the middle of the 17th century have been discovered. It is located 13 m north of the north-west corner of the Kamianitsa.
The structure was built on the basement. The interior details of the ground floor have preserved in the upper burnt layers of the consruction pit. To the left of the entrance, in the eastern corner, the remains of destroyed furnace were discovered, and to the right of the entrance, near the wall, a large stone (0.55 Ч 0.25 Ч 0.36 m) was found.
Fragments of kitchen and tableware dating to the first half — mid-seventeenth century were found in the filling of the building. Part of the tableware is decorated with green, yellow, light brown and brown glaze. In addition to the pottery there were also found parts of knives with bone grips, steel, spring and hinged scissors, a fragment of a pipe, fishing sinkers and horseshoes. Among the unique finds the seal cast made from copper alloy should be noted. In the burnt layer of the building and below it the items dated back to the 10th—12th centuries such as the bridle pendant (reshma), fragment of encolpion, bracelet, pin, fragment of a lunula which are made of copper alloy have been occurred, as well as the gold-glass bead, fragment of a glass bracelet, fragments of pyrophillit spindle wheel and plate. Probably during household works the residents of Lyubech of the 17th century accidentally found the old items, collected and stored them.
Thus, the discovered residential building belonged to the wealthy resident of Lyubech and was destroyed in fire in the middle of 17th century.
ABOUT THE SPREADING OF SOME TYPES OF METAL (COPPER-BRONZE) ORNAMENTS IN THE BURIALS THE EARLY AND MIDDLE BRONZE AGE OF THE STEPPE CULTURES OF UKRAINE
Authors: Chernykh L. A.
Published: November 2021

Based on the materials of the Yamnaya and the Catacomb CHC (culture-historical community), the types of forged ornaments of the burial garment, made on the basis of thin copper / bronze plates-beads and hoops, their morphological modifications, position on the garment, spreading in territorial and chronological aspects are analyzed. The quantitative characteristics are given against the background of a representative sample of burials from the main areas of the indicated cultures of Ukraine (tables 1—3). The irregular spreading of these types of jewelry was established, which is explained both by the technical capabilities of production and the specificity of local ethno-cultural traditions.
The massifs of the North-Western Black Sea region are distinguished by the quantitative predominance of spikes and small hoops, which emphasizes the special cultural context of the Budjak Culture of the Early Bronze Age in the region. The prevailing trend of their use in the composition of typesetting bracelets is also noted here. These types of jewelry are much less represented in other regions of the Yamnaya CHC, where the prevailing trend is their use in necklaces, hats or hairstyles, and the use of hoops in the decoration of a waist belt.
The appearance in burials of the EBA / MBA of rare finds of spiral beads, small items with punch ornaments, hoops-bracelets reflects the desire for a variety of «lamellar» decorations in the context of traditional technologies. Large hoops with punch ornaments are a special type. Being a continuation in the development of symbolic objects of steppe cultures of the Ponto-Ciscaucasian community, they are an innovation of the Early Catacomb tribes of the Northern Black Sea region.
The Middle Bronze Age is the time of the appearance of numerous types of cast ornaments, which to a certain extent replace forged ones, which took place mainly in Donets river region with sources of raw materials and close to the advanced technologies foci. Beads are found sporadically in the catacomb burials of Donets river region (Donetsk and Late Catacomb burials) and small hoops are absent. The Ingul Catacomb Culture is distinguished by the presence of small plate ornaments, which reflects the persistent archaism of local metalworking.
DEPICTING TRYPILLIA: THE EMERGENCE AND DECLINE OF REALISTIC STYLE
Authors: Shatilo L. O. , Hofmann R.
Published: November 2021

This study, once again, raises the question on the driving forces of stylistic development. For that, we focused on two prehistoric contexts, more specifically on Trypillia and the Late Neolithic site Vinča-Belo Brdo where we analyzed various objects with «realistic» images.
For Trypillia, we included the following categories: house models, sledge models, depictions of equipment for animal use on zoomorphic objects (figurines, vessels etc.), «realistic modelled» faces of anthropomorphic figures, and depictions on anthropomorphic figurines (hairstyles and accessories for hair, necklaces, footwear and clothes). Based on the latest findings on chronology, we trace the mentioned realistic features in time and space by means of quantifications and mapping. Additionally, we investigate the changes of anthropomorphic figurines in terms of size.
In the case study of Vinča, the frequency of realistic features in the different depths of the tell stratigraphy are put in relation to the total number of figurines and the historical dynamics of the late Neolithic societies.
The consideration of different material categories shows that objects with «realistic» characteristics mainly occur in certain periods and geographical regions that are characterized by specific historical developments. These include high population densities in large agglomerated settlements, increased innovativeness, intensive interaction in densified far-reaching communication and exchange networks.
In both case studies, the developments ended in fundamental crises and were associated with the disintegration of large settlements and population decline. Linked to this, some types of «realistic» objects disappear, others become fewer and lose their «realistic» characteristics.
FLAT AXES-CHISELS OF THE TRYPILLIA CULTURE FROM THE DNIEPER REGION
Authors: Hoshko T. Y.
Published: November 2021

Copper flat axes of the Szбkalhбt type are a fairly common type of tools in the contemporary withstages Trypillia BI—II, CI cultures of Central Europe. These tools are characterized by asymmetry of the profile — one curved side and a flat other. The collection of Trypillia metal of the National Museum of History of Ukraine contains five Szбkalhбt-type products from the excavations of V. Khvoyka. Due to the attribution, it was established that they originated from the settlements of Trypillia and Veremya (the last quarter of 5th millennium BC), Khalepya and Chernyakhiv (first half of 4st millennium BC). Flat axes from Trypillia, Veremia and Chernyakhiv belongs to the Szбkalhбt type, Vбroslőd variant. The axe-chisel from Halepya has no analogies.
Remains of seams on the side surfaces are often shifted to a flat surface. indicating casting in a two-sided form, one of the sash of which had a deeper negative than the other. Regarding the type of mold for casting flat axes from Trypillia, some questions arose. The presence of dents on its curved surface, which have been cast from a mold, may indicate the use of a model made of either wax or fired clay. Only in such a way could similar marks appear on the surface of the casting. It is concluded that the flat axel from Trypillia may have been cast according to the wax model. This technology has been known since the time of Varna Culture (5th millennium BC). But we do not know yet whether it was known to Trypillia population.
The tools are cast from copper, which contains minor impurities of other metals (from tenths to thousandths parts of a percent). This corresponds to the results of spectral analysis of the similar products from Central Europe.
The blade part was formed using forging: it has expanded sideways, the blade was given a more rounded shape. Sometimes the blade part was formed by the sediment of the cutting edge (Trypillia). The technology of casting flat axes blanks from the Middle Dniprо, followed by blacksmithing, does not differ from the Central European ones and is typical for the period of existence of these tools throughout their distribution. Smaller sizes and new original shapes, inherent only in the Dniprо products, indicate their local production.

Evolution of the artist's profession as an important factor in the art market development (from Antiquity to the Renaissance)
Authors: Pavlichenko Nadiia
Published: November 2021

The article describes artistic creativity as a professional activity and as an important factor in the art market development. It attempts to follow the evolution of the profession from craft to intellectual creativity in the period from Antiquity to the Renaissance. Thinking of art as a production process enables the important points that had a great impact on it to be highlighted: the role of the customer, the perception of artistic creativity by society, the self-awareness of artists, the organization of labor, etc. During Antiquity, the fine arts were perceived as technical ones arising from the mental activity of man and embodied in his work, so they were evaluated by the same criteria as other applied crafts. Throughout the Middle Ages, the church was the main customer of an art product, and fine arts were used as an improvised means of religious didactics. Scholastic authors perceived "mechanical" arts as lower ones, as noted. A significant rethinking of fine arts and the person creating it had been taking place during the 12th–14th centuries with the advent of the private customer. Recognition of fine arts as intellectual work has also significantly changed the working conditions of artists, the evaluation and perception of the artistic product, contributed to the further development of the art market.
Memorial buildings of Ternopil region (origins and formation of design in the XIX — first third of the XX century)
Authors: Odrekhivskyi Roman
Published: November 2021

Ternopil region today is the center of tourist routes. Many monuments of memorial stonework have been preserved here. Most of them are currently in an abandoned and little-studied state. Therefore, the research of memorial buildings is relevant today. The research methodology is based on systematics, reliability, logic, historicism. The purpose of the study is to begin a comprehensive work on the study, preservation, restoration of memorials and to explore the problem of using these art objects for tourism purposes. The author examined hundreds of memorial buildings in Ternopil region. Most of them have been developed and put into scientific circulation for the first time. In particular, in Terebovlya, Narayiv and other centers of stonemasonry. The national peculiarities of memorial constructions of masonry are considered, i.e. isosceles/ Greek type of crosses with endings in the form of a shamrock, peculiarities of iconography of drawings of figures of Saints, of Jesus Christ, etc., thematic variety of sculptural figures.
In the perspective of further research, it is recommended to provide theoretical justifications for the creation of lapidary museums of memorials in order to better preserve them for posterity and use as artistic objects for tourist routes.
Ida and the Cold War as (neo)modern movies
Authors: Platek Slawomir
Published: November 2021

The subject of the article is the analysis of the latest films by Paweł Pawlikowski in terms of their affiliation to trends in contemporary cinematography.
Ida and Cold War are sometimes described as the artistic heritage of the Polish Film School. The article focuses on the hypothesis that these films can, however, be attributed to the current of European neo-modernist cinema. Such a conclusion is based on the study of the author's creative path, the perception of Pawlikowski's work abroad and, above all, on the aesthetics of the films discussed in the article.
The theoretical basis for these conclusions are the works by Andre Bazin on the visual side and on the content of the films (ambiguity of the world presented in the films). The article concerns the concept of ‘realism’ in the theory of the French critic.
The second basis for conclusions is the work by Rafał Syska on the film trend known as neo-modernism. Paweł Pawlikowski's works meet many of Syska's postulates and seem to represent a poorly described trend present in Polish cinematography. It is a look at Ida and the Cold War that has not been included in Polish film research so far.
Pawlikowski's works are in many ways similar to some Polish productions from the 1960s. Such films are classified by Justyna Żelasko as modernist cinema, against the tradition that they are usually associated with the Polish Film School.
The composition of the film frames was also analyzed in reference to the nostalgic fashion called ‘lomography’.
Outlines of theoretical and practical parity in the legacy of Joseph Addison
Authors: Ternova Maryna
Published: November 2021

The article analyzes the situation in the scientific and artistic space of England in the transition period from classicism to the Enlightenment on the example of the legacy of Joseph Addison - a famous English writer, esthetician and politician. It was J. Addison who belonged to those intellectuals of his time who perceived, positively evaluated and - within their own capabilities - contributed to the "entry" of certain enlightenment ideas into the research space of the time. On the one hand, they significantly expanded the ideas of his contemporaries about the potential of aesthetic knowledge, the attribution of which at the turn of the seventeenth and eighteenth centuries, albeit slowly, but transformed from a rationalist model to the recognition of the positive role of sensory factors. The role of J. Addison's scientific research on the phenomenon of "aesthetic experience" and its possible interaction with "imagination" is emphasized. This theoretical orientation contributed to the formation of philosophical and psychological theory of imagination, which later became entrenched in the European research space thanks to J. Vico.
J. Addison's literary and theatrical environment was reconstructed, which intensified the popularization of his work in England, enabling the influence of the writer, poet and playwright on the current process of cultural creation and outlining the importance of his heritage in the national and European humanities due to the favourable assessment by R.G. Collingwood.
It is proposed to use the factors of culturological analysis - interdisciplinarity, personalization in the context of the biographical method, dialogism and formal-logical structure "theoretical-practical parity", as far as the transition from classicism to the Enlightenment taking into consideration the time was an important historical and cultural stage which can also be the object of theoretical analysis in the framework of cultural history and culturology.
Reproduction and communication of the text in current practices of urban spaces of the XXI century
Authors: Babii Nadiia
Published: November 2021

The aim of the work is to explore alternative ways of communication between poets and audience and methods for reproducing poetry through topical practices at the beginning of the XXI century. Accordingly, it aims to consider cultural and artistic experiments of the second decade of the 21st century developed on the basis of language as a symbolic sign and sound system; to identify the main directions of intermedial interaction, the degree of socio-cultural differentiation and variability of communicative agents. The author applies the method of intermedial analysis formed on the basis of post-structural and postmodern methodology as well as the systematic approach of the theory of communication. The synthesis procedure involves considering of the integral properties of synthetic practices that are not inherent to the constituent components. The study determines the intermedial ties in topical poetic practices of the 21st century. Plenty of communicative forms of presentation of poetic texts of the beginning of the 21st century reflect continuity with poetic practices of the 1990s but in the conditions of the screen culture of the hypermodern. New formations indicate the transition of literature from autonomy to mediality and intermediality, from authenticity to reproductivity, demonstrating transgression of borders between various spaces (real, virtual), artistic environments. Synthetic forms of topical practices such as performance, installation, flash mob, street art, show different directions of intermedial interaction in modern reproduction, attract a wide audience to cultural puncture, democratizing urban spaces.

FINANCIAL DISTRESS PREDICTION: A NOVEL DATA SEGMENTATION RESEARCH ON CHINESE LISTED COMPANIES
Authors: Zhu Fang-Jun , Zhou Lu-Juan , Zhou Mi , Pei Feng
Published: November 2021

In the Chinese stock market, the unique special treatment (ST) warning mechanism can signal financial distress for listed companies. In existing studies, classification model has been developed to differentiate the two general listing states. However, this classification model cannot explain the internal changes of each listing state. Considering that the requirement of the withdrawal of ST in the mechanism is relatively loose, we propose a new segmentation approach for Chinese listed companies, which are divided into negative companies and positive companies according to the number of times being labeled ST. Under the framework of data mining, we use financial indicators, non-financial indicators, and time series to build a financial distress prediction model of distinguishing the long-term development of different Chinese listed companies. Through data segmentation, we find that the negative samples have a huge destructive interference on the prediction effect of the total sample. On the contrary, positive companies improve the prediction accuracy in all aspects and the optimal feature set is also different from all companies. The main contribution of the paper is to analyze the internal impact of the deterioration of financial distress prediction in time series and construct an optimization model for positive companies.
Energy consumption, physical properties, protein structure and digestibility of edible insects dried using three methods
Authors: Chaowattanakul T. , Khieu V.M. , Rojviriya C. , Siriwong S. , Jittanit W. , Chanput W.P.
Published: November 2021

This study evaluated the effects of three drying techniques, tray drying, roasting and microwave vacuum drying, on the physical properties, secondary structures,in vitro protein digestibility and X-ray tomographic structure of crickets (Acheta domesticus) and mulberry silkworm pupae (Bombyx mori L.). The protein contents of dried crickets and silkworm pupae were 49-54% and 51-53% (dry basis), respectively. Roasting produced a significantly higher browning index than the other two methods for crickets and silkworm pupae. The microwave vacuum-dried crickets exhibited the lowest hardness, with hardness values of approximately half those of the tray-dried and roasted crickets. Tray-drying and microwave vacuum drying silkworm pupae produced similar hardness values, which were lower than that of roasted silkworm pupae. The energy consumption of the tray dryer was the lowest, followed by the roaster and microwave vacuum dryer. No significant changes in the secondary protein structure of dried silkworm pupae were observed. A significant decrease in α-helix and β-turn and increase in β-sheet was observed in roasted crickets. Cricket and silkworm pupae powders produced from all drying techniques could be easily digested (90-95% digestibility). This work presents valuable knowledge for understanding the effects of different drying techniques on the properties of dried edible insects, aiming to support the production of alternative and sustainable protein sources for the growing population to improve food security.
Detection of Elder Abuse Among Orthopedic Patients

Published: November 2021

Approximately 10% of US adults experience elder abuse, which often manifests as musculoskeletal and soft tissue injuries. The goal of our study was to determine the rate of elder abuse among orthopedic surgery patients and characterize which patients may be at an increased risk. National Inpatient Sample Healthcare Cost and Utilization Project data from 2001 to 2015 were parsed with the Clinical Classifications Software tool. Patients 60 years and older were identified byInternational Classification of Diseases, Ninth Revision(ICD-9), code for elder abuse. Primary orthopedic procedures and subsequent inpatient diagnoses and comorbidities were used to develop a binary logistic regression model to predict an elder's risk of abuse. Of a total of 20,532,211 admissions for an orthopedic procedure, 0.010% (2084) were classified as elder abuse. Patients with a classification of abuse more commonly were women (74.8% vs 60.6%) and from the lowest socioeconomic quartile by income (28.5% vs 21.7%). In addition, these patients had hospital stays that were twice as long (10.2 vs 5.3 days) and had higher admission mortality rates (4.4% vs 1.2%). No primary orthopedic procedures were associated with a higher risk of elder abuse. Nonorthopedic diagnoses made during admission that were associated with increased risk of abuse included superficial injury or contusion (odds ratio [OR], 3.252), chronic skin ulcer (OR, 3.119), nutritional deficiency (OR, 3.418), fluid and electrolyte disturbances (OR, 1.729), and delirium or dementia (OR, 2.210). The incidence of elder abuse among orthopedic surgery patients is significantly lower than national estimates. This finding warrants further investigation to determine whether it is a function of underreporting or differences in patient populations, given the 4-fold increase in mortality risk.

This article is concerned with the existence of entire solutions for the following complex second order partial differential-difference equation

   \begin{document}$ \left(\frac{\partial^2 f(z_1, z_2)}{\partial z_1^2}+\frac{\partial^2 f(z_1, z_2)}{\partial z_2^2}\right)^{l}+f(z_1+c_1, z_2+c_2)^{k} = 1, $\end{document}

where $ c_1, c_2 $ are constants in $ \mathbb{C} $ and $ k, l $ are positive integers. In addition, we also investigate the forms of finite order transcendental entire solutions for several complex second order partial differential-difference equations of Fermat type, and obtain some theorems about the existence and the forms of solutions for the above equations. Meantime, we give some examples to explain the existence of solutions for some theorems in some cases. Our results are some generalizations of the previous theorems given by Qi [23], Xu and Cao [35], Liu, Cao and Cao [17].

Higher education (HE) in Kuwait suffers from high dropout rates, and one of the leading causes of this desertion is a lack of academic advising. Effective academic advising systems must fulfill its users' needs and provide a positive user experience (UX), which allows users to successfully and effectively fulfill their goals. This study used quantitative and qualitative approaches to evaluate an electronic advising system (e-advisor) used by the Public Authority for Applied Education and Training (PAAET). Survey data from 1,095 PAAET students were analyzed to determine students' perceptions and evaluate their experience using e-Adviser. The findings indicated that students were aware of the features and advantages of e-Advisor. Overall, the participants had a moderately positive impression of e-Advisor's UX. The system's attractiveness, efficiency, and perspicuity were rated slightly higher than its dependability, stimulation, and novelty. Moreover, female students' perceptions of e-Advisor's UX were significantly more favorable than their male counterparts.

Owing to the importance of a subject like Mathematics in the teaching and learning of science, self-learning often poses a challenge to the educator. The objective of this study is to analyse the enhancement of the textual and the media form of self-learning modules to teach Algebra and Geometry to eighth graders considering their retention levels. A pre-test post-test single-group quasi experimental design was tested and tried out on 49 participants of a school. The 20 modules of self-learning material covering content in the topics of Algebra and Geometry in the textual and media-assisted forms of self-learning were administered over three months. The findings of the study revealed the ability of media-assisted self-learning modules to enhance achievement in the post-test when compared to the pre-test. The textual-assisted learning modules was able to enhance significant difference in the achievements in Geometry, but not of Algebra. The delayed post-test results were found to indicate an improved achievement in Mathematics.

Authors: Sharma Sourabh , Sharma Megha
Published: November 2021

Education in today’s epidemic time is possible only through virtual learning platforms. COVID-19 has changed the mode of learning and shown the power of learning in virtual mode. In this paper a self-designed questionnaire on virtual learning was developed to analyse the impact of virtual learning on undergraduate and postgraduate university students. The self-developed questionnaire containing 25 items is tested for validity and reliability. 25 items are further segregated into 5 factors using exploratory factor analysis. These five factors are: Virtual Learning Environment; Virtual Learning and Health Related Issues; Virtual Learning and Interpersonal Issues; Virtual Learning and Technological Issues; Virtual Learning Deliverables. To have the comparative study of undergraduate and postgraduate students for the use of virtual learning platforms, one-way ANOVA is implemented. One-way ANOVA is implemented for each factor and it was found that virtual learning effectiveness increases when students move from Under graduation (UG) to Post Graduation (PG) in India.

Abstract Temperature and salinity are essential ocean variables for understanding the oceans' physical processes. The conductivity and temperature measurements are used for deriving ocean salinity. Conductivity-temperature (CT) sensors mounted on moored buoys are widely used
to collect sustained time-series observations of temperature and salinity. However, these measurements are prone to drifts that need to be corrected to ensure data quality. The present study evaluates a field validation technique to correct the drift in subsurface temperature and conductivity
measurements that can potentially complement the standard calibration procedure performed by the original equipment manufacturer. The advantage of field validation is that it could be carried out soon after retrieving CT sensors, which ensures that the physical conditions and configuration
of the retrieved CT sensors remain unaltered from that of the in-situ conditions. The drift in the CT sensors was analyzed by pre-deployment and post-retrieval field validation of CT sensors. A correction is applied to the raw data assuming a linear trend in drift with time. An ice test to
identify and correct the errors in the timestamp of CT measurements is also discussed.

Published: November 2021

AbstractBecause of the unpredictable range of propagation, knowledge of the wave transmission properties of the aquatic environment is needed for efficient underwater electromagnetic (EM) wave activity. Most publications concern low frequencies to achieve long contact distances, and data transmission is widely known to be captivated with one of the critical parameters, frequency. However, there are some new applications that need data in order to be implemented underwater over short distances. This survey provides a detailed overview of current underwater communication techniques, as well as their advantages and disadvantages. Potential future directions and recommendations for enabling next-generation underwater wireless networking systems are discussed. This paper also summarizes radio-frequency communication studies and, as a result, developments in radio-frequency identification technology for data transmission in a variety of aquatic environments, including freshwater and saltwater.
Review and Analysis of Blockage of Suez Canal Region Due to Giant Container Ship

Published: November 2021

Abstract Navigation through narrow waterways always requires expertise and help from local authorities to facilitate safer and faster navigation. The recent Suez Canal blockage by the ultra-large container ship Ever Given running aground has resulted in a temporary
halt and extended delay in goods transportation. Blockage of such a critical waterway has raised major concerns about the risk involved in navigation. This commentary attempts to analyze the background and chain of events leading up to the blocking of the Suez Canal. In this process, the issues
related to navigation and following up salvage efforts are analyzed to identify the critical areas of improvement. Based on these identifications, suggestions for future improvement of navigation and better preparedness to optimize the salvage efforts have been identified. These suggestions
include digitalization, prediction-based navigation capabilities, development of tugboats and associated tools, and so forth.

Published: November 2021

COVID-19 virus is a serious threat to public health everywhere on the planet. The World Health Organization (WHO) declared the disease epidemic in December 2019 because of its rapid prevalence around the world. The disease is transferred by inhalation or contact with contaminated droplets, and the incubation period varies from 2 to 14 days. COVID-19 has led to unprecedented pressures as demand for healthcare in hospitals and intensive care units around the world increases. As the epidemic intensifies, determining the resulting needs for health care resources (beds, staff, equipment) has become a priority for many countries. Predicting future demand requires estimating how long COVID-19 patients must have access to different levels of hospital care. The length of hospitalization for these patients is one of the management priorities. It is possible to pass through the crisis only with careful planning and comprehensive cooperation.

Published: November 2021

Introduction: Intimate partner violence has been recognised globally as a human rights violation. It is universally under-diagnosed and the institution of timeous multi-faceted interventions has been noted to benefit intimate partner violence victims. Currently the concept of using a screening tool to detect intimate partner violence has not been widely explored in a primary healthcare setting in South Africa, and for this reason the current study was undertaken. The objectives of this study were: (1) to determine the operating characteristics of a two-question screening tool for intimate partner violence (Women Abuse Screening Tool–short); and (2) to estimate the prevalence of intimate partner violence among women attending an outpatient department, using a validated questionnaire (Women Abuse Screening Tool). Methods: A cross-sectional study was conducted prospectively at the outpatient department of a primary care hospital, with systematic sampling of one in eight women over a period of three months. Participants were asked about their experience of intimate partner violence during the past 12 months. The Women Abuse Screening Tool–short was used to screen patients for intimate partner violence. To verify the result of the screening, women were also asked the remaining questions from the full Women Abuse Screening Tool. Results: Data were collected from 400 participants, with a response rate of 99.3%. Based on the results for the Women Abuse Screening Tool, the prevalence of intimate partner violence in the sample was 32%. The Women Abuse Screening Tool–short was shown to have a sensitivity of 45.2% and specificity of 98%. Conclusion: With its high prevalence, intimate partner violence is a health problem at this facility. The Women Abuse Screening Tool–short lacks sufficient sensitivity and therefore is not an ideal screening tool for this primary care ambulatory setting. The low sensitivity can be attributed to the participants’ understanding of the screening questions, which utilise Eurocentric definitions of intimate partner violence.  Improvement in the sensitivity of the Women Abuse Screening Tool–short in this setting may be achieved by lowering the threshold for a positive result.
