Published: October 2022

Background: Premature birth occurs before 37 weeks of complete gestation, weighs less than 2,500 grams, and is the main cause of newborn death and the second cause of death in children under five. Premature babies are at higher risk for illness, disability, and death. Changes in heart rate in premature babies can occur after being given a recording of the mother's voice, which contains 3 types: speaking, reading, and singing. The results showed an effect of recording the mother's voice on changes in heart rate in premature infants. This community service activity aims to increase nurses' knowledge about the importance of the mother's voice on changes in the heart rate of premature babies. Methods: Community service activities were carried out twice. The first activity was carried out through a zoom meeting which explained the importance of the mother's voice in premature babies with the help of PowerPoint media. Then continued, the second activity in the form of a demonstration of Mother's voting. Results: The pre-test showed that 9 nurses (100%) had less knowledge about the importance of the mother's voice for the heart rate of premature babies. After receiving education and demonstration regarding the mother's voting, the post-test results were that 7 nurses (78%) had good knowledge and 2 nurses (22%) had poor knowledge. Conclusion: Nurses become aware of the importance of the mother's voice in increasing the heart rate of premature babies.
A xCT role in tumour-associated ferroptosis shed light on novel therapeutic options
Authors: Criscuolo Daniela , Morra Francesco , Celetti Angela
Published: October 2022

Solute carrier family 7 member 11 (SLC7A11; also known as xCT), a key component of the cystine/glutamate antiporter, is essential for the maintenance of cellular redox status and the regulation of tumor-associated ferroptosis. Accumulating evidence has demonstrated that xCT overexpression, resulting from different oncogenic and tumor suppressor signaling, promotes tumor progression and multidrug resistance partially via suppressing ferroptosis. In addition, recent studies have highlighted the role of xCT in regulating the metabolic flexibility in cancer cells. In this review, the xCT activities in intracellular redox balance and in ferroptotic cell death have been summarized. Moreover, the role of xCT in promoting tumor development, drug resistance, and nutrient dependency in cancer cells has been explored. Finally, different therapeutic strategies, xCT-based, for anti-cancer treatments have been discussed.
The Effect of Data Characteristics and Top Management Characteristics on Decision Making Capabilities: The Role of AI and Business Analytical Capability
Authors: Alarefi Mohammed
Published: October 2022

Data is essential for making decisions. However, these data should be appropriately collected and analyzed by capable managers. Few studies examined the effect of data characteristics (DC) and top management characteristics (TMC) on decision-making capability (DMC). In addition, few examine the application of artificial intelligence enterprise resource planning (AIERP) in this process. The purpose of this study is to examine the effect of DC and TMC on DMC. Building on existing theories and studies, this study proposed that DC (data integrity, data quality, data authentication, and data error) significantly affect the DMC. In addition, TMC (data analytical capability and technological innovation) significantly affect the DMC. AIERP is predicted to have a mediator role between DC and TMC, and DMC. Business analytical capability (BAC) is anticipated as a moderating variable. The data was collected from technological companies in the Gulf Cooperation Council (GCC). A purposive sampling technique was deployed. The findings using SmartPLS 4.0 showed that DC and its components expect data authentication and TMC and its components have significant effects on DMC. AIERP mediated the effect of DC and TMC on DMC while BAC did not moderate the effect of DC and TMC on DMC. Decision-makers have to focus on collecting high-quality data and ensuring the data is free from error. Decision-makers also have to use technology to enhance the quality and effectiveness of decisions.

THE THRACIANS AND THE WRITING
Authors: SLAVOVA Mirena
Published: October 2022

The article offers a summary and analysis of the available texts written in the Thracian language, which became especially necessary after the breakthrough finding in 1988 of new written monuments in Thracian in the settlement of Zone on the Aegean coast in Greece.
Contrary to popular belief that the Thracians were an illiterate people, it can be concluded that by the 4th century BC there were three centers of writing activity in the Thracian lands: Northeastern Bulgaria (the inscription from the village of Kjolmen), the Upper Thracian plain (the inscription on the ring from the village of Ezerovo and the inscriptions on artifacts from the mounds of Duvanlii), and the Aegean coast (inscriptions from the settlements of Zone and Maroneia and from the island of Samothrace).
The author examines the written evidence of the Thracian language in the context of the neighboring Greek alphabets and concludes that the existence of a local alphabet used by the Thracian population before the arrival of the Greek colonists on the Aegean coast can be postulated. Another focus of the paper is related to understanding the reasons for the gradual demise of the practice of writing in the Thracian language in the context of the emergence of the Greek local alphabets and the cultural and political reality of contacts with the Greek-speaking population and education, without neglecting the sociolinguistic aspects of the problem.

LEXICAL AND SEMANTIC PARALLELS IN THE DESIGNATION OF TIME IN THE BULGARIAN DIALECTS AND THE SLAVIC DIALECTS OF THE CARPATHIANS
Authors: KONDRATENKO Mikhail
Published: October 2022

The article examines the peculiarities of the designation of time periods in the Bulgarian dialects and in the Ukrainian dialects of the Carpathian region, mainly from the point of view of the specifics of dialect segmentation of this semantic sphere and the principles of nomination. The lexical material of the Ukrainian dialects of the Carpathians and dialects of the Bulgarian language allows us to identify within the framework of the article some semantic models and shifts that exist in time designations: orientation in the names of months to phenological cycles and periods of work; perception of the concept of "time" displayed by vocabulary as a favorable or unfavorable time for any activity or life in general; nomination of morning as the appearance of daylight or a period of time slightly removed in the past from the moment of speech; borrowings are also noted as part of the vocabulary denoting time in its various manifestations. Based on the analysis of dictionaries of the Carpathian-Ukrainian and Bulgarian dialects, it is concluded that this vocabulary represents semantic models of names of time periods that have parallels in other Slavic and some non-Slavic languages. Taking into account the wide distribution in the linguistic territory of Slavia, as well as beyond its borders, it is possible to assume the status of these models as semantic archetypes, represented in their totality in the Carpathian-Ukrainian and Bulgarian dialects.
THE CASE OF PARTISAN COMMANDER LEVANEVSKI – BETWEEN CRIMINAL AND POLITICAL DISCOURSE
Authors: VODENICHAROV Petar
Published: October 2022

The article is part of a larger study of documents related to one of the communist regime's biggest crimes – the massacre without trial and the conviction of local elites (25-30 000 people) in a particularly sadistic way. The study is based on David Ovadia's documentary "Levanevsky" dedicated to a participant in the Partisan Fighters’ Movement, convicted not only for political but also for criminal offences and who led the sadistic murders of innocent civilians after the communist coup. The questions I want to answer to are: what are the reasons for the moral relativism of the author who tries to justify Levanevsky as a legendary hero. How long can anti-fascist rhetoric legitimize any crimes regardless of their scale and cruelty; what are the biographical psychoanalytical causes of communist sadism? The psychoanalytical analysis (linguistic turn in psychoanalysis) reveals a recurring biographical scheme – a despotic mother and an uninteriorized fatherly authority, which is not compensated by the symbolic networks of kinship, religion, school, army, profession. The involvement of criminals in the partisan movement compromises the anti-fascist movement – an atmosphere of fear, power battles, arbitrary killings and robberies was brought about.
Reconstracting the life trajectory of Levanevski who was used and misused by the communists (killed without court and sentence after the communists took power) we could consider him as a representative of the peasant anarchism rather than the conscious antifascist struggle. Statistic data about the social and educational status of the Bulgarian partisan fighters (1941 -1944) are also provided.

Authors: Lee Madeline Y. , Barounis Kya , Hazen Andrea L. , Aarons Gregory A. , Fettes Danielle
Published: October 2022

Accreditation could potentially improve an under-resourced, overburdened child welfare system. As the first study to use national-level data to focus on the Council on Accreditation (COA) in public child welfare, this research note explores: 1) the landscape of accreditation and 2) how accreditation is related to agencies’ structure (environment of care, organizational capacity). According to COA data from 2018, 29 child welfare agencies in the U.S. were accredited—four state-administered, two counties in state-administered systems, eight counties in one hybrid system, and 15 county-administered. Data from the second National Survey of Child and Adolescent Well-Being (NSCAW II) found that, while accredited and non-accredited agencies were comparable on most structural factors, participation in Title IV-E waiver demonstration projects and less collaboration with substance abuse treatment providers were associated with accreditation. This research note sets the foundation for further evaluating accreditation's impact in child welfare.
Applying the Health Belief Model and Organization-Public Relationship Quality to Examine COVID-19 Health Behaviors and Public Health Messaging
Authors: Nichols Aaron
Published: October 2022

In the context of the most severe pandemic in over 100 years, this study examined public health behavior and public health messaging using the health belief model (HBM) and organization-public relationships (OPR) as frameworks. The study employed a cross-sectional survey of students ( n = 288) and employees ( n = 203) at a large public university in the southeastern United States. First, the study empirically tested the components of the HBM as determinants of engaging in health behaviors meant to mitigate the spread of COVID-19 and, supporting prior HBM research, found all components of the model to be significantly related to engaging in the health behaviors. Next, the study found the relationship between the university's public health messaging and OPR quality to be statistically significant. Additionally, findings indicated that OPR quality was significantly related to engaging in the health behaviors. This study contributes to both theory and practice with significant findings that provide a direction for further translational research utilizing the HBM and OPR to examine public health communication.

Published: October 2022

A colony of the rare hydrozoan siphonophore Lilyopsis Chun, 1885, was observed for the first time in shallow water in False Bay, South Africa, swimming amongst kelp. A study of a high-quality image of this individual found it to share some characters with the prayine prayid L. fluoracantha Haddock, Dunn & Pugh, 2005, so far known only from Monterey Bay, California, in the eastern Pacific. No Lilyopsis species has previously been reliably identified from either the South Atlantic or the Indian Ocean, so this record represents an expansion of the known worldwide distribution for this genus.
Remarks on the exotic flora of Capo Mortola (Ventimiglia, northern Italy) and its changes over time
Authors: Mariotti Mauro , Zappa Elena
Published: October 2022

In this study, we compared current data and data of the census made in the 1990s related to the vascular flora of Capo Mortola (Ventimiglia, Italy), considering 270 taxa not dependent on crop management. The current status reported 198 alien species: 5 invasive, 65 naturalized 75 casual, 38 occurring as casual in human-dominated systems, but without direct intervention by humans and not close to parent plant, 15 occurring as casual alien, but still with some uncertainties for a definitive classification, and plus 3 cryptogenic and 1 eradicated (extinct) taxa, while in 1996 were 229 species: 87 naturalized and 142 adventitious (casual). Of these, 40 taxa show an increasing trend and 41 a decreasing or disappearing trend. If we consider the wild areas of Capo Mortola, 10 taxa are new to the Italian flora (7 casual and 3 naturalized) while 13 are new to the Ligurian flora only (all casual). If we also consider the neglected areas of the Botanical Gardens, 18 new casual species for the Italian flora and 10 for the Ligurian one would be added. In addition, 9 status changes are proposed on a national scale and 17 on a regional scale. An in-depth analysis was conducted on the presence and the local history of a subset of 34 exotic plants, 11 of which are new or have a new status for the Italian flora.

Effects of pitch length of perforation on the crease bending characteristics of a polypropylene sheet subjected to indentation of a perforation blade
Authors: Nagasawa Shigeru , Hosokawa Tomoki
Published: October 2022

This study reveals the bending formability of a polypropylene (PP) sheet indented by a perforation blade when changing the pitch of the dashed-ruled line and the indentation depth. Creasing is a folding method of a carton sheet in which a score (called as a ruled line) is made at the bent portion. When making a creased line on a resin sheet, the scored sheet thickness decreases by applying half cutting or creasing (pressing) at the bent portion to make it easier to fold. To smoothly process a folding line on the resin sheet, a dashed line using a perforation blade is sometimes considered. The pitch length of the dashed line, and its nicked (uncut) length, affect the crease bending characteristics of the resin sheet scored by the perforation blade. However, only a limited number of studies have analyzed the dashed line bending moment response. In this study, to clarify the bending formability of a 0.5-mm-thick PP sheet indented by a developed perforation blade, first, the influence of the perforation pitch length on the crease bending characteristics of a scored PP sheet was investigated from a 0.5-mm fine pitch up to an 8-mm commercially sold pitch with a cutting-to-pitch length ratio of 50%. Second, the nicked zone depth against the cutting tip was set as 50% of the 0.5-mm thickness of the PP sheet. Furthermore, it was revealed that burrs (wedged bottom) in the cut part of the perforated (dashed) line affected the bending moment resistance in the folding process of the scored PP sheet, when changing the indentation depth of the perforation blade.

Then, using the newly established identity, we prove some new general versions of Bullen and trapezoidal type inequalities for differentiable convex functions. The main benefit of the newly established inequalities is that they can be converted into similar inequalities for classical integrals, Riemann-Liouville fractional integrals, $ k $-Riemann-Liouville fractional integrals, Hadamard fractional integrals, etc. Moreover, the inequalities presented in the paper are extensions of several existing inequalities in the literature.

The transient electromagnetic inversion of detection signals mainly depends on fast inversion in the half-space state. However, the interpretation results have a certain degree of uncertainty and blindness, so the accuracy and applicability of the three-dimensional full-space inversion need to be investigated. Two different three-dimensional full-space inversions were carried out. First, the numerical characteristic parameters of the response signals were extracted. Then, the correlations between the numerical characteristic parameters and physical parameters of the water-bearing abnormal bodies were judged, and the judgment criterion of the iterative direction was proposed. Finally, the inversion methods of the iterative algorithm and the BP neural network were utilized based on the virtual example samples. The results illustrate that the proposed numerical characteristic parameters can accurately reflect the response curve of the full-space surrounding rock. The difference in the numerical characteristic parameters was used to determine the update direction and correction value. Both inversion methods have their advantages and disadvantages. A single inversion method cannot realize the three-dimensional inversion of the physical parameters of water-bearing abnormal bodies quickly, effectively and intelligently. Therefore, the benefits of different inversion methods need to be considered to comprehensively select a reasonable inversion method. The results can provide essential ideas for the subsequent interpretation of the three-dimensional spatial response signals of water-bearing abnormal bodies.
Ideological Entanglements of Family Policy and Their Consequences – Could the Charter of Family Rights Help to Solve the Dilemmas?
Authors: Kamiński Tadeusz
Published: October 2022

Decisions related to family policy are the results of settlement of axiological dilemmas, understood as the necessity to make a choice between different types of good. These settlements are made on the basis of adopted and implemented ideologies. The article discusses the main assumptions of family policy in the liberal, conservative, social liberal and feminist perspective. Then it presents selected consequences of ideological entanglement of family policy on the example of state interference in matrimonial and procreation decisions, the right to raise children and to reconcile parental and professional obligations. The final part of the text discusses the Charter of the Rights of the Family as an example of a proposal that aims to go beyond the strict ideological framework of state policy towards the family.

Published: October 2022

Hot corrosion behavior of a powder metallurgy superalloy (Alloy 1) in molten 95% Na2SO4+5%NaCl salts at 800 °C are investigated with average corrosion rate calculation, X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy spectrum analyzer (EDS). Meanwhile, the hot corrosion tests of Alloy 2 at 800°C were also carried out for comparison. Experimental results show that the corrosion layers obtained after 100h of hot corrosion were mainly composed of Cr2O3, Al2O3 , NiO , Ni3S2 , NiCr2O4 and Cr2S3 at 800 °C. The cross-sectional morphologies and corresponding elemental maps indicate that a large amount of sulfides and oxides appeared in internal substrate. According to these results, the cooperating mechanism of oxidation and sulfuration in Na2SO4-NaCl salts for Alloy 1 is confirmed. Compared with Alloy 2, the increased Co and Al content in Alloy 1 with better hot corrosion resistance at 800 °C promoted the rapid formation of continuous Cr2O3 and Al2O3 protective films on the alloy surface in which Co inhibited internal oxidation of Al and reduced internal diffusion of S through the third element effect.

Hot corrosion behavior of a powder metallurgy superalloy (Alloy 1) in molten 95% Na2SO4+5%NaCl salts at 700 °C, 750 °C and 800 °C are investigated with average corrosion rate calculation, X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy spectrum analyzer (EDS). Experimental results show that the average corrosion rate of Alloy 1 increases as the temperature elevates. The corrosion layers obtained after 100h of hot corrosion were mainly composed of Cr2O3, TiO2, Al2O3 , NiO and Ni3S2 at each temperature, meanwhile NiCr2O4 and Cr2S3 appeared at 750 °C and 800 °C respectively. The cross-sectional morphologies and corresponding elemental maps indicate that lots of Ni-Ni3S2 eutectic appeared in corrosion layers and a large amount of sulfides and oxides appeared in internal substrate. According to these results, the combined mechanism of oxidation and sulfuration in Na2SO4-NaCl salts for Alloy 1 is confirmed. Compared to Alloy 2, the increased Co and Al content in Alloy 1 with better hot corrosion resistance at 800 °C promoted the rapid formation of continuous Cr2O3 and Al2O3 protective films on the alloy surface in which Co inhibited internal oxidation of Al and reduced internal diffusion of S through the third element effect.

Effects of low angle boundaries (LABs) on the stress rupture properties of bicrystals of a nickel-based third generation single crystal superalloy at 1093 °C/158 MPa were investigated. The results show that the effect of LABs on the stress rupture elongation of the alloy is higher than that of the stress rupture life at 1093 °C/158 MPa. As the misorientation angle of the LABs reaches 9.0°, the stress rupture life of the alloy with LABs can still retain nearly 50% of that with LABs of 0° at 1093 °C/158 MPa; while the stress rupture elongation of the alloy with LABs drops obviously when the misorientation angle of the LABs is larger than 6.5°. The fracture surfaces of stress ruptured alloy with LABs of 0°~2.9° are characterized by dimple features, while those with LABs of 6.5°~12.3° all exhibit intergranular fracture features. Apparent dimple features can be observed at the intergranular fracture surface of the alloy with LABs of 6.5° and the elongation of it is high. However, obvious dendrite features can be observed at the intergranular fracture surfaces of the alloy with LABs of 7.6°~12.3° and the elongations of them are relatively low.

The microstructure, texture, and tensile properties of hot extruded Mg-6Zn-1Y-1Ce alloy obtained at a temperature range of 300 °C to 400 °C were studied. Electron back-scatter diffraction (EBSD) results revealed that strong basal plane texture was found along extrusion direction in the sample extruded below 340 °C due to discontinuous dynamic recrystallization (DRX) mechanism. In the sample extruded at 340 °C the average value of Schmid factor (SF) of {0001}〈11-20〉 slip system was 0.09. However, the sample extruded above 370 °C had weak basal texture under the control of continuous DRX mechanism, and the SF was well-distributed with an average value of about 0.32. The strengths of as-extruded samples decreased with increase of extrusion temperatures. In addition to fine grain strengthening, texture strengthening had a significant contribution to the high strength for the sample extruded at low temperature.
Effect of Boron Content on the Transverse Stress Rupture Properties of a Directionally Solidified Superalloy

Published: October 2022

The effect of boron content on the transverse stress rupture properties of a directionally solidified columnar superalloy is studied in present research. The experimental results indicate that the transverse stress property of the alloy containing 0.015% boron reaches the peak value at 870°C /380MPa while that of the alloy with 0.005% boron is the best at 1100°C/40MPa. At 870°C, dislocation slip is the main deformation mode. Stress concentration is induced when dislocations are hindered by precipitates at grain boundaries and interdendritic regions. And then cracks nucleate due to the stress concentration. In the alloy containing 0.015% boron, no borides precipitate and boron strengthens the grain boundary cohesion by solid solution. At 1100°C, grain boundary movement becomes the main deformation mode. In the alloy with 0.005% boron, the strengthening of grain boundary cohesion decreases comparing with that of alloy with 0.015% boron, and the resistance to grain boundary movement reduces with decreasing B content. Therefore, it results in compatible deformation between adjacent grains, resulting in the longest stress rupture lifetime.

The main issues that limit the large-scale application of TiO2 in photocatalysis is its low utilization of solar energy and high recombination rate of photogenerated charges. To overcome these limitations, a type II WO3·H2O/TiO2 heterojunction has been prepared via a one-step mild hydrothermal method that uses Na2WO4·2H2O and P25 as the starting materials and proceeds at 150°C without requiring any post-heat treatment for crystallization, special solvents or additives. The XRD and HRTEM results show that the prepared powders were composed of orthorhombic WO3·H2O and TiO2, and demonstrate the existence of the WO3·H2O/TiO2 heterojunctions. The photocatalytic activity of the as-prepared WO3·H2O/TiO2 heterojunction powders was investigated by using the degradation of phenol. The WO3·H2O/TiO2 heterojunction powders exhibited the best photocatalytic performance when the nominal W/Ti ratio was 6.57%, and showed better photocatalytic performance than commercial P25 and orthorhombic WO3·H2O.
