BackgroundUnderstanding the occurrence and severity of child injuries is the cornerstone of preventing child injuries. Currently, there is no standardized child injury surveillance dataset in China.MethodsMultistage consultation by a panel of Chinese experts in child injury to determine items to include in the core dataset (CDS) was performed. The experts participated in two rounds of the modified Delphi method comprising a consultation questionnaire investigation (Round 1) and a face-to-face panel discussion (Round 2). Final consensus was established based on the opinions of the experts regarding the modified CDS information collection items. Enthusiasm and authority exhibited by the experts were evaluated by the response rate and using the expert authority coefficient, respectively.ResultsThe expert panel included 16 experts in Round 1 and 15 experts in Round 2. The experts during both rounds had a high degree of authority, with an average authority coefficient of 0.86. The enthusiasm of the experts was 94.12%, and the proportion of suggestions reached 81.25% in Round 1 of the modified Delphi method. The draft CDS evaluated in Round 1 included 24 items, and expert panelists could submit recommendations to add items. Based on findings in Round 1, four additional items, including nationality, residence, type of family residence, and primary caregiver were added to the draft of the CDS for Round 2. After Round 2, consensus was reached on 32 items arranged into four domains—general demographic information, injury characteristics, clinical diagnosis and treatment, and injury outcome—to include in the final CDS.ConclusionThe development of a child injury surveillance CDS could contribute to standardized data collection, collation, and analysis. The CDS developed here could be used to identify actionable characteristics of child injury to assist health policymakers in designing evidence-based injury prevention interventions.

IntroductionIn recent years, job crafting has greatly interested Work and Organizational Psychology. Different research studies have shown its positive impact on people and organizational performance. However, it knows little about the differential effect of the two dimensions that make up this variable (prevention-focused and promotion-focused) and its role in the health-impairment spiral process of the job demand-resources theory (JD-R).MethodThis research aims to analyze the mediating effect of the different dimensions of job crafting on the influence of burnout on performance and self-efficacy in the workplace. The study used a sample of 339 administrative employees of a university.ResultsThe results indicate that promotion-focused job crafting is a mediating variable in the relationship between the influence of burnout on performance and self-efficacy. Unexpectedly, prevention-focused job crafting does not have this mediating role in the same relationship.DiscussionThese findings confirm the adverse impact of burnout on personal and organizational improvement, while showing the absence of prevention/protection responses of employees when they are burned out. The theoretical and practical implications show an advance in knowledge about the process of health deterioration and about the spiral of health deterioration in the JD-R theory.

IntroductionEvidence supports both the positive and negative effects of Internet use on mental health outcomes, but it remains unclear on the role of online social support in this relationship. This study examined the link between daily hours of general Internet use and bidimensional mental health (BMMH) through the pathway of online social support (OSSS).MethodsDrawing from a sample of 247 Filipino university students, this cross-sectional study tested two simple mediation models that considered mental wellbeing and psychological distress as outcome variables.ResultsFindings show that the total effect of Internet use is positive and negative for mental wellbeing and psychological distress, respectively. Online social support mediated the favorable effects of Internet use on BMMH outcomes. However, the introduction of OSSS as a mediator yielded residual direct effects with opposing signs for both models. The resultant inconsistent mediation in the models signifies the double-edged impact of Internet use on mental health, with favorable effects transmitted through online social support.DiscussionFindings highlight the importance of online social support as a pathway to harness the positive effects of Internet on mental health. Recommendations to improve online social support for students are discussed herein.
Structure-Circuit Resistor Integrated Design Optimization of Piezoelectric Energy Harvester Considering Stress Constraints

Published: April 2023

A piezoelectric energy harvester (PEH) transduces mechanical energy into electrical energy, which can be utilized as an energy source for self-powered or low-power devices. Therefore, maximizing the power of a PEH is a crucial design objective. It is well known that structural designs are firstly conducted for controlling resonance characteristics, and then circuit designs are pursued through impedance matching for improving power. However, a PEH contains solid mechanics, electrostatics, and even a circuit-coupled multi-physics system. Therefore, this research aims to design a PEH considering a circuit-coupled multi-physics. As a design process, a conceptual design is developed by topology optimization, and a detailed design is developed sequentially by applying size optimization as a post-processing step to refine the conceptual design results for manufacturable design. In the two optimization processes, design optimizations of a structure coupled with circuit resistor are performed to maximize the power, where the electrical and mechanical interactions between PZT, substrate, and circuit resistor are simultaneously considered. Additionally, stress constraints are also added for structural safety to ensure operational life of PEH. As a result of the proposed design methodology, a manufacturable design of PEH having maximum power and operational life is obtained with power density of 6.61 μWg−2mm−3.
Automatic Classification Method of Arrhythmias Based on 12-Lead Electrocardiogram
Authors: Yang Xiao , Ji Zhong 
Published: April 2023

Cardiovascular disease is one of the main causes of death worldwide. Arrhythmias are an important group of cardiovascular diseases. The standard 12-lead electrocardiogram signals are an important tool for diagnosing arrhythmias. Although 12-lead electrocardiogram signals provide more comprehensive arrhythmia information than single-lead electrocardiogram signals, it is difficult to effectively fuse information between different leads. In addition, most of the current researches working on automatic diagnosis of cardiac arrhythmias are based on modeling and analysis of single-mode features extracted from one-dimensional electrocardiogram sequences, ignoring the frequency domain features of electrocardiogram signals. Therefore, developing an automatic arrhythmia detection algorithm based on 12-lead electrocardiogram with high accuracy and strong generalization ability is still challenging. In this paper, a multimodal feature fusion model based on the mechanism is developed. This model utilizes a dual channel deep neural network to extract different dimensional features from one-dimensional and two-dimensional electrocardiogram time–frequency maps, and combines attention mechanism to effectively fuse the important features of 12-lead, thereby obtaining richer arrhythmia information and ultimately achieving accurate classification of nine types of arrhythmia signals. This study used electrocardiogram signals from a mixed dataset to train, validate, and evaluate the model, with an average of F1 score and average accuracy reached 0.85 and 0.97, respectively. Experimental results show that our algorithm has stable and reliable performance, so it is expected to have good practical application potential.

Published: April 2023

We design and evaluate two experimental systems for a single and simultaneous electro-optical semiconductor optical amplifier Mach-Zehnder interferometer (SOA-MZI) mixing system based on the differential modulation mode. These systems and the optimization of their optical and electrical performance largely depend on characteristics of an optical pulse source (OPS), operating at a frequency of f= 39 GHz and a pulse width of 1 ps. The passive power stability of the electro-optical mixing output over one hour is better than 0.3% RMS (root mean square), which is excellent. Additionally, we generate up to 22 dBm of the total average output power with an optical conversion gain of 32 dB, while achieving a record output optical signal to noise ratio (OSNR) up to 77 dB. On the other hand, at the SOA–MZI output, the 128 quadratic amplitude modulation (128-QAM) signal at an intermediate frequency (IF), f1, is up-mixed to higher output frequencies nf ± f1. The advantages of the resulting 128-QAM mixed signal during electrical conversion gains (ECGs) and error vector magnitudes (EVMs) are also evaluated. The performed empirical SOA-MZI mixing can operate up to 118.5 GHz in its high-frequency range. The positive and almost constant conversion gains are achieved. Indeed, the obtained conversion gain values are very close across the entire range of output frequencies. The largest frequency range achieved during experimental work is 118.5 GHz, where the EVM achieves 6% at a symbol rate of 10 GSymb/s. Moreover, the peak data rate of the 128-QAM up mixed signal can reach 70 GBit/s. Finally, the study of the simultaneous electro-optical mixing system is accepted with unmatched performance improvement.
PROBLEMS OF THE FUNCTIONING OF ORPHANAGES IN VOLYN IN THE 1920S
Authors: Vlasyuk Igor 
Published: April 2023

The purpose of the article is to analyze the state and problems of the functioning of orphanages in soviet Volyn in the 1920s. On the basis of acts of inspection of orphanages and other documents, deficiencies were found that prevented the normal stay of children in these institutions. Important importance was attached to political and ideological work with children of orphanages and teaching staff.
The research methodology includes the principles of scientificity, historicism, authorial objectivity, as well as general scientific (analysis, synthesis, generalization), comparative (when characterizing the state of various orphanages) and special-historical (historical-systemic (when analyzing the structure and functions of these institutions), historical-typological (to identify general features of the functioning of orphanages) methods.
The scientific novelty consists in a comprehensive study and an attempt to objectively analyze the problem of the functioning of orphanages in this region in the mentioned period; involvement of new archival documents in scientific circulation.
Conclusions. The results of prolonged military confrontations between representatives of various Ukrainian political forces, the Russian White Guards and the Bolsheviks caused significant destruction and victims among the civilian population. Like any war, that one provoked an increase in the number of orphaned children who, being on the streets, turned into a problem that needed a solution. Child homelessness had a number of negative consequences including an increase in the criminogenic situation. The creation and operation of orphanages should have become one of the problem solutions. However, the analysis of the state of these institutions in only one region, in Volyn, confirms the opinion that the Soviet government in the 20s of the XX century was unable to solve the issue of maintaining and providing high-quality living conditions for a significant number of orphans. Underfunding was among the main reasons of that. Semi-ruined buildings without heating and sanitary facilities, lack of beds, clothes and shoes for children were typical conditions for the orphaned under the Soviet authorities’ care during the researched period. The consequences of staying in such conditions were venereal diseases, pediculosis, scabies, tuberculosis and this is an incomplete list of the diseases those children got. Unfortunately, the more important task for the authorities was not solving these problems but the obligation to carry out political and educational work among the orphanages staff and pupils.
Godforsakennes as an Absolute of the World Modelled by the Ukrainian Novel Discourse of the Second Half of the XIX Century
Authors: Matvieieva T. 
Published: April 2023

The problematic of the article concerns motivating the prospects of studying the artistic modelling as a peculiar display of the author’s intentions. The study is based on the Ukrainian novel discourse of the second half of the XIX century. The following methods were in the article: cultural-historic, partly-semantic, psychological, the method of motif analysis.
The main attention is paid to man as the central element of the world model. The results of the observations prove that it is man who is the main destructive factor that makes the modelled world unstable, causes its deformations – social, ideological, economic, cultural. A particular aspects of the study is the objective and subjective conditions of being self-harmonisation, of mutual balance of aspirations and possibilities of their realization, shown on the example of the works in which the social, the psychological dominates in the view of the world and man in it, novels of the wide problem-thematic range and worldview esthetics. The above made it possible to make a surmise about the dominance of a tendency of individual’s disadaptation under the conditions of global social changes, hence distorted ideas about the moral-ethical priorities, the dialectics of the spiritual and the material in the process of creating being.
The article also deals with the issues of purely mental shifts in a person’s being, a person’s levelling, mainly represented in the analyzed novels through the binary opposition ''breaking out / estrangement (from the family, nation, beliefs, faith)'' that manifest itself in mental disorders, melancholic states, apathy. Stone in the article is the symbol of that process as in point to a person’s withdrawal from the commandment about the love to their fellow-creatures.
The techniques through which the authors localized the above mentioned processes were singled out, among them the rising gradation, oxymoron. It is them that helped to depict the godforsaken world in which man will never become a complete, integral character, remaining a person for whom the goal of their own existence and the future of the world are not clear.
A conclusion is drawn that studying the total of artistic models in the diachrony of the literary process development will form a macroworld that is maximally similar to the objective one.
The Expletive Emergence in the Sentence Structure of Some Germanic Languages
Authors: Polkhovska M. 
Published: April 2023

The article deals with the investigation of the reasons of expletive emergence in the structure of the sentence and its generation position. The expletive appearance in the sentence structure depends on the possibility of the associative φ-features checking in the TP projection and varies in the Germanic languages. In Icelandic, it occurs in two positions: with or without an external argument (associative). The external argument, if present, behaves as the subject, it moves to the position of the TP (the external argument cannot remain in situ). In this case, the expletive is introduced into the sentence structure only not to allow the associative to move to the position [Spec, СP]. If the sentence contains only the internal argument of the predicate, the expletive may stay nin situ (vP) or move to [Spec, CP] position. In these sentences, the appearance of the expletive is considered to prevent the associative movement to CP projection, and to guarantee of the presence of the subject in the n absence of an external argument. In other Germanic languages, the expletive is a formal argument that moves tothe [Spec, TP] position to be marked with case and to check EPP-feature. The problem of compulsory filling of the [Spec, TP] position in the Germanic languages remains unresolved. Comparing the sentence word order and the position of the subject in the Germanic languages, we can conclude that SVO- type languages have a EPP-feature; in languages with the V2-rule and SOV word order, this feature is deleted selectively (the subject may be generated in the [Spec, CP] position).
"They Did not Know How to Build Their Own State, so They Were in Someone Else's Hands": Artistic Concept of the Liberation Struggle of the Ukrainian People in the Leonid Poltava Novel "Above the Blue Black Sea"
Authors: Tymoshchuk N. 
Published: April 2023

The peculiarities of the artistic modeling of historical reality of 1917–1920 by Leonid Poltava in the novel "Above the blue Black Sea" are considered in the article, the specificity of the artistic text is also clarified by the researcher. The novel "Above the blue Black Sea" Leonid Poltava is unfairly left out of contemporary literary criticism in the scientific Ukrainian space. The main plot is the events of the Civil War period in Ukraine, Turkey, Bulgaria and the Czech Republic.
Leonid Poltava has systematically analyzed the causes of the failure of the Central Council and its allies; he is sure that they have created the conditions for "soviet" totalitarianism and the embodiments of the Bolsheviks basic principle the devide et impera in life. The author has used two approaches to realizing his plan; they are a research and aesthetic ones; Leonid Poltava has skillfully combined historical facts and literature, science and art. The prevailing place in the large gallery of characters is occupied by historical figures, representatives of various warring camps (Hetman Skoropadskyi, Symon Petliura, Troitskyi, Nestor Makhno, Kutiepov, etc.). It is, of course, determined by the specifics of the genre. In our opinion, all the fictional characters, episodes from their lives are closely linked to the historical specifics of the first decades of the twentieth century. They give the novel a significant artistic value. Leonid Poltava recreated the image of the whole people in the documentary-historical concretization of being through every "non-historical" personality, human destiny, action and moral position. The work is characterized by an objective third-form narrative; such a narrative causes the reader to experience the self-deployment of the narrative, the absence of any biased considerations.
In conclusion, Leonid Poltava skillfully recreated the civil war as a historical reality, modeled the political, social, cultural and mental processes of that days in the novel "Above the blue Black Sea". The writer studied its nature in detail, investigating the behavior of the masses as the main creator of history in the turbulent age of 1917-1920. Of course, the author was not a direct witness of these terrible events, but the artistic means reminded compatriots of these liberation burials. Now the work of Leonid Poltava has become extremely relevant, the problems raised by the author are close to modern Ukrainians.
Borrowings from Romance Languages in the Northern Ukrainian Monuments of the XVI– XVII Centuries
Authors: Tytarenko V. 
Published: April 2023

Borrowing is one of the most productive ways of expanding the vocabulary of any language. These questions are devoted to individual monographs, dissertations, articles and works indirectly touching the problem. However, today there is a need for a dictionary of borrowed vocabulary, the development of a unified methodology for the study of borrowed tokens, the detection and establishment of a real percentage of the borrowings in the Ukrainian language at different periods.
Different ways of the descriptive method have been used, by means of observations tokens of foreign origin have been discovered, with the help of methods of generalization and classification. In the article selected borrowings are distributed according to thematic groups and the interpretation of observation results is also used. We also used applying techniques of comparable and comparative-historical method.
The material that was analyzed by us has shown that borrowings from the Romance languages in the old Ukrainian monuments of business style, written in Polissya, in comparison with the Polonisms, Latins, Germanisms are not so many. The content of the thematic groups is limited, first of all, it is a household vocabulary (the names of fabrics and articles of them, ornaments, singly shoes), military vocabulary (the names of weapons), sporadically the names of food and drinks (wine). Borrowings from these languages are represented by a specific vocabulary, which testifies to the fact that they penetrated together with the reality that was designated. On the basis of lexicographic sources, it was established that these terms appeared mainly through the intermediation of other languages.
Having fallen into the old Ukrainian language, adapted romanisms were subjected to the same processes as the specific vocabulary, in particular the active words used to be expanded, the narrowing of semantics; after the disappearance of reality, went to the periphery (archaic), part with certain semantic changes is now preserved in the north-Ukrainian dialect.
