A neuro-symbolic system over knowledge graphs for link prediction
Authors: Rivas Ariam , Collarana Diego , Torrente Maria , Vidal Maria-Esther
Published: June 2023

Neuro-Symbolic Artificial Intelligence (AI) focuses on integrating symbolic and sub-symbolic systems to enhance the performance and explainability of predictive models. Symbolic and sub-symbolic approaches differ fundamentally in how they represent data and make use of data features to reach conclusions. Neuro-symbolic systems have recently received significant attention in the scientific community. However, despite efforts in neural-symbolic integration, symbolic processing can still be better exploited, mainly when these hybrid approaches are defined on top of knowledge graphs. This work is built on the statement that knowledge graphs can naturally represent the convergence between data and their contextual meaning (i.e., knowledge). We propose a hybrid system that resorts to symbolic reasoning, expressed as a deductive database, to augment the contextual meaning of entities in a knowledge graph, thus, improving the performance of link prediction implemented using knowledge graph embedding (KGE) models. An entity context is defined as the ego network of the entity in a knowledge graph. Given a link prediction task, the proposed approach deduces new RDF triples in the ego networks of the entities corresponding to the heads and tails of the prediction task on the knowledge graph (KG). Since knowledge graphs may be incomplete and sparse, the facts deduced by the symbolic system not only reduce sparsity but also make explicit meaningful relations among the entities that compose an entity ego network. As a proof of concept, our approach is applied over a KG for lung cancer to predict treatment effectiveness. The empirical results put the deduction power of deductive databases into perspective. They indicate that making explicit deduced relationships in the ego networks empowers all the studied KGE models to generate more accurate links.
Dynamic system models and their simulation in the Semantic Web
Authors: Stüber Moritz , Frey Georg
Published: June 2023

Modelling and Simulation (M&S) are core tools for designing, analysing and operating today’s industrial systems. They often also represent both a valuable asset and a significant investment. Typically, their use is constrained to a software environment intended to be used by engineers on a single computer. However, the knowledge relevant to a task involving modelling and simulation is in general distributed in nature, even across organizational boundaries, and may be large in volume. Therefore, it is desirable to increase the FAIRness (Findability, Accessibility, Interoperability, and Reuse) of M&S capabilities; to enable their use in loosely coupled systems of systems; and to support their composition and execution by intelligent software agents. In this contribution, the suitability of Semantic Web technologies to achieve these goals is investigated and an open-source proof of concept-implementation based on the Functional Mock-up Interface (FMI) standard is presented. Specifically, models, model instances, and simulation results are exposed through a hypermedia API and an implementation of the Pragmatic Proof Algorithm (PPA) is used to successfully demonstrate the API’s use by a generic software agent. The solution shows an increased degree of FAIRness and fully supports its use in loosely coupled systems. The FAIRness could be further improved by providing more “ rich” (meta)data.
Enhancing awareness of industrial robots in collaborative manufacturing

Published: June 2023

The diffusion of Human-Robot Collaborative cells is prevented by several barriers. Classical control approaches seem not yet fully suitable for facing the variability conveyed by the presence of human operators beside robots. The capabilities of representing heterogeneous knowledge representation and performing abstract reasoning are crucial to enhance the flexibility of control solutions. To this aim, the ontology SOHO (Sharework Ontology for Human-Robot Collaboration) has been specifically designed for representing Human-Robot Collaboration scenarios, following a context-based approach. This work brings several contributions. This paper proposes an extension of SOHO to better characterize behavioral constraints of collaborative tasks. Furthermore, this work shows a knowledge extraction procedure designed to automatize the synthesis of Artificial Intelligence plan-based controllers for realizing flexible coordination of human and robot behaviors in collaborative tasks. The generality of the ontological model and the developed representation capabilities as well as the validity of the synthesized planning domains are evaluated on a number of realistic industrial scenarios where collaborative robots are actually deployed.

Authors: Nascimben Mauro , Lippi Lorenzo , Fusco Nicola , de Sire Alessandro , Invernizzi Marco , Rimondini Lia
Published: June 2023

BACKGROUND: Establishing baseline measurements on normative data is essential to evaluate standards of care and the impact of clinical or surgical treatments. Hand volume determination is relevant in pathological conditions where the anatomical structures might undergo modifications like post-treatment chronic edema. For example, one of the consequences of breast cancer treatment is the possibility of developing uni-lateral lymphedema on the upper limbs. OBJECTIVE: Arm and forearm volumetrics are well-studied techniques, whereas hand volumetry computation poses several challenges both from the clinical and digital perspectives. The current work has explored routine clinical and customized digital methodologies for hand volume appraisal on healthy subjects. METHODS: Clinical hand volumes computed by water displacement or circumferential measurements were compared to digital volumetry calculated from 3D laser scans. Digital volume quantification algorithms exploited the gift wrapping concept or cubic tessellation of acquired 3D shapes. This latter digital technique is parametric, and a calibration methodology to define the resolution of the tessellation has been validated. RESULTS: Results on a group of normal subjects demonstrated that the volumes computed from digital hand representations extracted by tessellation return values similar to the clinical water displacement volume assessment at low tolerances. CONCLUSIONS: The current investigation suggested that the tessellation algorithm could be considered a digital equivalent of water displacement for hand volumetrics. Future studies are needed to confirm these results in people with lymphedema.

Published: June 2023

BACKGROUND: Cardiac dysfunction accompanies acute ischemic stroke and affects the effective implementation of early rehabilitation interventions. There is a lack of reference hemodynamic data on cardiac function in the subacute phase of ischemic stroke. OBJECTIVE: In this study, we aimed to identify appropriate cardiac parameters for exercise training utilizing a pilot study. METHODS: We used a transthoracic electrical bioimpedance non-invasive cardiac output measurement (NICOM) device to monitor cardiac function in real time for two groups [i.e., subacute ischemic stroke inpatients group (n= 10) and healthy control group (n= 11)] using a cycling exercise experiment. The parameters of both groups were compared to highlight the cardiac dysfunction in the subacute phase in patients with ischemic stroke. RESULTS: We considered stroke volume index (SVI) and systemic vascular resistance index (SVRi) as the primary outcomes, and there was significant intragroup difference (stroke group: P< 0.001; control group: P< 0.001, using one-way ANOVA) and significant intergroup difference at each individual time segment (P< 0.01, using independent t-test). Among the secondary outcomes, i.e., cardiac index (CI), ejection fraction (EF), end-diastolic volume (EDV), and cardiac contraction index (CTI), we found significant intergroup differences in CI, EF, and CTI scores (P< 0.01, using independent t-test). Significant interaction with respect to time and group were seen only in the SVRi and CI scores (P< 0.01, using two-way ANOVA). There was no significant inter- or intra-group differences in EDV scores. CONCLUSION: SVRI, SVI, and CI values highlight cardiac dysfunction in stroke patients the most. At the same time, these parameters suggest that cardiac dysfunction in stroke patients may be closely related to the increased peripheral vascular resistance caused by infarction and the limitation of myocardial systolic function.

Authors: Wu Jiaqi , Heng Modi , Bai Yunyang
Published: June 2023

BACKGROUND: The minimally invasive endodontics could retain more peri-cervical dentin (PCD) and other important dental structures, thus realizing the minimal loss of teeth structures and preserving the strength and function of the endodontically treated tooth (ETT). The search for abnormal root canals or calcified root canals could be quite time-consuming and increase the risk of perforation. OBJECTIVE: This study introduced a novel multifunctional 3D printing guided splint inspired by the dice, which can achieve the minimally invasive access cavity preparation and canal orifice identification. METHOD: Data were collected from an outpatient with dens invaginatus. Cone-beam Computed Tomography (CBCT) revealed a type III invagination. The CBCT data of the patient were imported into a computer-aided design (CAD) software (Exocad 3.0; Exocad GmbH) for the 3D reconstruction of jaw bones and teeth. The dice-inspired 3D printing guided splint consists of the sleeve and guided splint. The sleeve with minimal invasive opening channel and orifice locating channel were designed with a reverse-engineering software (Geomagic Wrap 2021). The reconstructed models in the Standard Template Library (STL) format were imported into a CAD software. The design of the template was aided by the dental CAD software in Splint Design Mode. The sleeve and splint were exported into the STL files separately. A 3D printer (ProJet® 3600 3D Systems) was used to separately generate the sleeve and guided splint, and was made by stereolithography and processed in a medical resin (VisiJet M3 StonePlast). RESULTS: The novel multifunctional 3D printing guided splint could be set in position. The opening side in the sleeve was selected and the sleeve was inserted in place. The minimal invasive opening was made in the crown of the tooth to access the pulp. The sleeve was draw out and turned to the orifice location side, and then inserted in place. The target orifice was located rapidly. CONCLUSION: This novel dice-inspired multifunctional 3D printing guided splint allow dental practitioners to gain accurate, conservative, and safe cavity access from teeth with anatomical malformations. Complex operations might be carried out with less reliance on the operator’s experience than with conventional access preparations. This novel dice-inspired multifunctional 3D printing guided splint would have a broad application in the dental field.

Published: June 2023

BACKGROUND: The emergency rescue ability of firefighters is particularly important in the event of major disasters or accidents. Therefore, an assessment of the firefighter-training effectiveness is necessary. OBJECTIVE: This paper aims to achieve a scientific and effective assessment of the firefighter-training effectiveness in China. An assessment method based on human factor parameters and machine learning was proposed. METHOD: The model is constructed by collecting the corresponding human factor parameters such as electrocardiographic signals, electroencephalographic signals, surface electromyographic signals, and photoplethysmographic signals through wireless sensors and using them as constraint indicators. For the problems of weak human factor parameters and high noise proportion, an improved flexible analytic wavelet transform algorithm is used to denoise and extract the corresponding feature values. To overcome the limitations of traditional assessment methods, improved machine learning algorithms are used to comprehensively assess the training effectiveness of firefighters and provide targeted training suggestions. RESULTS: The effectiveness of this study’s evaluation method is verified by comparing it with the expert scoring method and considering firefighters from a special fire station in Xhongmen, Daxing District, Beijing, as an example. CONCLUSION: This study can effectively guide the scientific training of firefighters and the method is more objective and accurate than the traditional method.

BACKGROUND: The anesthesia machine serves as a vital piece of lifesaving equipment. OBJECTIVE: To analyze incidents of failures in the Primus anesthesia machine and address these malfunctions to reduce recurrence of failure, save maintenance costs, enhance safety, and improve overall efficiency. METHODS: We conducted an analysis on the records pertaining to the maintenance and parts replacement of the Primus anesthesia machines used in the Department of Anaesthesiology at Shanghai Chest Hospital over the past two years to identify the most common causes of failure. This included an assessment of the damaged parts and degree of damage, as well as a review of factors that caused the fault. RESULTS: The main cause of the faults in the anesthesia machine was found to be air leakage and excessive humidity in the central air supply of the medical crane. The logistics department was instructed to increase inspections to check and ensure the quality of the central gas supply and ensure gas safety. CONCLUSION: Summarizing the methods for dealing with anesthesia machine faults can save hospitals a lot of money, ensure normal hospital and department maintenance, and provide a reference to repair such faults. The use of Internet of Things platform technology can continuously develop the direction of digitalization, automation, and intelligent management in each stage of the “whole life cycle” of anesthesia machine equipment.

Published: June 2023

The article uses approaches to the comparison of rock-crushing working bodies based on the use of complex indicators of the quality of construction machines used on construction sites. The use of such indicators is due to the need for constant improvement of existing equipment and the creation of new ones taking into account existing needs. Today, in Ukraine, there is a need for efficient implementation of construction works related to the laying of main pipelines. This, in turn, poses the task of determining the efficiency of performing mechanized earthworks during the laying of engineering networks. Complex indicators are grouped by characteristics. The first group includes indicators of classification, purpose, reliability, manufacturability, standardization and unification, patent law, aesthetics, ergonomics, safety. The second group consists of economic indicators. The third group is defined by indicators of competitiveness. Indicators of the 4th group and above evaluate the main groups of subsystems of machines or complexes of energy and technological purposes.
The need to create competitive earthmoving equipment requires the use of modern constructive solutions and their objective comparison at the design stage. In the course of the study, earthmoving working bodies for laying engineering networks of the type "cone cutter" and "end working body" in the form of a disk were compared. A comparison of the nominal and oscillating modes of operation of the end working body is also proposed. Design features of the working body of the type "cone cutter" and "end working body" are described. The results are summarized in the form of tabular data.
The proposed technical solutions open the possibility of variable use of rock-crushing work equipment of construction machines in accordance with the economic requirements and needs of the end user. The effectiveness of using the methods of comprehensive assessment of technical solutions lies in the possibility of their analysis by individual indicators, in combination, as well as when ranking the values of individual indicators according to significance.

purpose of the study is to study the adaptive capabilities of the cardiovascular system of schoolchildren living near the Chornobyl Exclusion Zone. Research methods. Anthropometric, instrumental, mathematical and statistical. Results. The study covered 1139 schoolchildren aged 6-17 years (579 boys, 560 girls) who live in rural settlements of Ivankivskyi and Polisskyi districts located near the Chornobyl Exclusion Zone. The survey included the determination of the specific activity of 137Cs (Bq/kg) in the body of children, followed by the calculation of the median and interquartile range in the analyzed groups; physical performance of schoolchildren with the definition of the Ruffier index; assessment of the level of functioning of the cardiovascular system and its adaptive potential. Most of the examined children showed tension and poor adaptation of the cardiovascular system. Disruption of adaptation mechanisms in schoolchildren was recorded in 17.38 % of cases, while in the group of girls with increased body weight it was determined significantly more often than in the group of boys. The reason for this situation, taking into account the genetic characteristics and specific activity of 137Cs in the body, may be hypodynamia. Satisfactory adaptation, as an indicator of health and stable balance of all systems of the child's body, was determined only at the level of 5-7 %. It was concluded that it is necessary to constantly monitor the adaptive capabilities of the cardiovascular system in schoolchildren living near the Chornobyl Exclusion Zone in order to prevent the development of serious diseases in them in the future. When assessing physical development and the state of the cardiovascular system, it is also necessary to take into account the level of incorporated radionuclides and the state of the genetic apparatus of the folate cycle.

The 3RIVE 3D pesticide application system, developed by FMC and Micro-Trak Systems Inc., allows to reduce the amount of pesticides used increasing their effectiveness. This innovative delivery platform converts the traditional high-volume application technology into a low-volume one thanks to the patented technology. The purpose of the work is risk assessment of the bifenthrin influence on the population health when consuming corn grown using the innovative 3RIVE 3D technology. Materials and methods. We calculated the stability indices of bifenthrin (the active ingredient of the Brigade 3Rive 3D, SC formulation) in corn grown using the innovative 3RIVE 3D technology (introduction into the soil with simultaneous sowing of corn seeds). Brigade 3Rive 3D, SC is used as an insecticide on corn crops with a maximum consumption rate of 1.2 l/ha, once. Research results and their discussion. When studying the dynamics of bifenthrin residual amounts in corn grown with the Brigade 3Rive 3D, SC formulation application using 3Rive3D technology, it was established that during the growing season the content of bifenthrin in corn gradually decreased and after 50 days in the ears of corn it was below the limit of quantitative determination of the method. The integral index of hazard when consuming pesticides contaminated food products (IIHCPCF) = ADD+С+ τ50 = 2+2+2 = 6 points (Table 2). That is, according to this index, bifenthrin can be attributed to compounds of the 3rd class of hazard (moderately hazardous compounds), since its moderate toxicity (ADD value) is combined with its moderate resistance in agricultural crops and the relative low corn amount in the diet of Ukrainians. Conclusions. It was established that according to State Standard 8.8.1.002-98 bifenthrin belongs to the 3rd class of hazard – moderately stable compounds. According to the value of integral index of hazard when consuming pesticides contaminated food products bifenthrin can be assigned to the 3rd class of hazard (moderately hazardous compounds). As the application of the Brigade 3Rive 3D, SC formulation using 3Rive3D technology for the protection of corn does not carry the risk of crops pollution and consumption of corn by the population, deterioration of the ecological situation, as well as it has significant agro-economic and population safety advantages, the application of pesticides using 3Rive3D technology is very promising and will be actively and widely implemented in the agricultural practice of Ukraine in the future.

Objective. Development of guidelines of healthy physical activity volume for school-age children of the quarantine measures Materials and methods. Results of a survey of physical activity (PA) and mental health of children and adolescents of school age (n=1354) were included in the study. Anthropometrical-physiological parameters and the level of well-being were determined in 39 children of primary school age. The optimal duration and frequency of various PA for different age and gender groups was determined by constructing linear regression models. Statistical analysis was carried out using STATISTICA 8.0. Results and discussion. Increased physical activity significantly reduces depression (r=– 0,25; p<0,001) and anxiety levels (r=– 0,14; p<0,001). Also the relationship between the duration of MVPA and anxiety indicators (r=–0.10; p<0.001) and depression indicators (r=–0,22; p<0,001) was determined. The recommended duration of the total PA (PAt, more than 2 hours a day) was observed during the quarantine by 42.5±2.4% of students of the younger age group, 36.6±2.3% of students of the middle age group and 33.3±2.3% high school students. It is determined that the chances having the middle and high levels of well-being are 8 times higher in the group of children who have PAt more 2 hours/day during the quarantine (OR = 8,0; CІ 1,54-41,63) and are 8,2 times higher - who have MVPA more 60 minute/day (OR = 8,17; CІ 1,41-47,22). The indicator of the total duration of physical activity was normalized according to the maximum value of the indicator for each age group and gender to check the developed standards. Conclusions. It is determined that the daily duration PAt for school-age children during the quarantine measures for the purpose of prevention depression disorders should be more 2 hours/day for primary school children and 2.2 hours/day for adolescents. The favorable for mental health minimal duration of MVPA, which is typical of most sports, for primary school children is amount 60 minutes/day for boys and 40 minutes/day for girls, for adolescents is 60 minutes/day for boys and 45 minutes/day for girls. The daily duration of MVPA for preventing of depressive disorders of primary school children is about 40 minutes/day for girls and about 60 minutes/day for boys. For preventing of anxiety disorders of primary school children is about 40 minutes/day for girls and about 50 minutes/day for boys, respectively. A single health-enhancing duration of sporting activity is 1,2-1,5 hours for primary school children and 1,5-2,0 hours for adolescents.

Antonovych, as a collector and collector of Ukrainian antiquities and historical monuments, was one of the first historians-local historians in Ukraine, an organizer of museum work, a museum theorist, ethnographer, and archaeologist. The works of V. B. Antonovych can be considered as comprehensive studies of a local history nature, since his field of vision included issues of historical and geographical local history, local genealogy, spragistics, heraldry, protection of historical and cultural monuments, and others. The scientist’s scientific interests in the field of local history went beyond regional studies, although the emphasis was on the study of Right Bank Ukraine, which ultimately influenced his statist views.
Emergent Worship: A Study on "Contemplation" in the Emerging Church
Authors:   ,   Andrews University, Milosavljevic Filip
Published: June 2023

Due to great interest and popularity of various contemplative practices among youth leaders, clergy, and church members across all denominational—including Seventh-day Adventism—and religious lines, this project will analyze the nature of selected Emergent contemplative practices, in particular those promulgated by the CAC. The primary goal is to find out whether “contemplation” and contemplative practices, as promoted by Richard Rohr, Cynthia Bourgeault, and their Emergent colleagues, are appropriate in Christian worship. This study will also contrast such contemplative practices and spirituality with the concept of contemplation in the Bible and in the writings of Ellen G. White. As a scientific addendum to this study, a short section will be dedicated to the effects contemplative practices have on the human mind. The study will then look into the deeper purpose of the practice of contemplation from both the Emergent and Seventh-day Adventist perspective. The final portion of the study will suggest Biblical principles for prayer in the light of knowledge concerning contemplative prayer as advanced by the Emerging movement. The study will end with a final and post conclusion.
A Feast to My Eyes: Color and Human Behavior
Authors:   ,   Andrews University, Bruso Erica
Published: June 2023

This is a study on color and how it affects emotion and human behavior. Color can both affect and express a person's mood. We see this played out by Pablo Picasso, whose Blue and Rose period paintings consisted of a dominant color expressing his emotions. Impressionist painters, such as Claude Monet, were fascinated with the variations of color that are produced in certain light conditions, different times of day, weather conditions, and seasons. By using studies on color and human behavior done by color specialists, such as Faber Birren, as well as looking back at color explorations of early painters, graphic designers can learn to utilize color in such a way that is not only visually pleasing, but also enhances the voice of their work, and viewers can become better aware of the influences of their behavior, which often play out in their actions.
God Is Amor: Biblical Teachings for House and Home, Translated from Spanish to English
Authors:   ,   Andrews University, Breetzke Melissa
Published: June 2023

I have transcribed and translated (from Spanish to English) a series of five video sermons by Pastor Homero Salazar to aid him in broadening his evangelistic efforts. While transcription requires structural fluency and a discerning ear, translation demands extensive conceptual consideration. Translators must weigh the tone, formality, intention, and implications of the original message and relay these concepts through linguistic equivalents in an alternate language. Some of the most interesting challenges of this project arose from changing the media from a dialogue-like video to a document for publication, requiring considerable pragmatic adjustments.

Christian Record for the Blind (CRSB) offers free Christian publications and services to all who are legally blind. In order to help CRSB better understand the people they serve and plan how to meet the needs of their users, CRSB conducted a major surbey through Andrews University that evaluated the products, services, and key ministry personnel of CRSB. The qualitative portion of the research was conducted through focus group interviews, which revealed themes of digital media accessibility, website quality, concerns of discrimination, disparities between Canadian and US services, and personal treatment and service of representatives.
The Design and Creation of a Portable Water Purification System
Authors:   ,   Andrews University, Shull Adam
Published: June 2023

A portable, low-power water purification system was developed for use by aid workers in underdeveloped world regions. The design included activated carbon and ceramic candle filtration to 0.2 microns for bacteria and turbidity reduction followed by UV irradiation for virus destruction. Flexibility and modularity were incorporated into the system with AC, DC, and environmental power supply options as well as the facility to purify water from either surface or local utility sources. Initial prototype testing indicated the successful filtration of methylene blue dye to well above the 75% UV transmittance level required for virus destruction by the UV reactor.
Inter-group Communication During Hurricane Katrina: How Organizational Culture Defeats Coordination
Authors:   ,   Andrews University, Nielsen Johanna
Published: June 2023

Interaction between groups can be understood as regulated by two communication theories: Adaptive Structuration theory which describes how a group's resources affect how it solves problems, and Functional Group Decision Making theory which describes the steps groups take to make decisions. When combined into a model, these theories provide a framework for examining how groups use resources in their interaction with each other. Research into both secondary and primary sources identified ten resources groups used to interact with other groups during the crisis response. Careful analysis determined that the Federal, State, and Private agencies' organizational cultures and social identities were resources that the agencies did not manage well which in turn led to poor coordination.
Bringing Back Jobs: the Factors That Influence Decisions to Offshore and Reshore Jobs Back to the U.s.
Authors:   ,   Andrews University, Wahlen Jessica
Published: June 2023

Offshoring has become an integral aspect of many American businesses. Companies may choose to sent some or all of thier manufacturing and service-related jobs to other countries for a variety of reasons. These reasons may be financial (e.g. lower labor costs abroad) or strategic (e.g. a desire to keep core competencies within the U.S., while sending other jobs abroad). Tariffs, quotas, and local content requirments placed on companies may also influence these decisions. A relatively recent trend has been the return of some of these offshored jobs to the U.S. In this project, I refer to this trend as "reshoring." Despite companies' original reasons to offshore, some find they have equally good reasons to reshore jobs. These reasons may be economic (e.g. an increase in minimum wages abroad), strategic (e.g. ability to advertise as 'Made in America'), operational (e.g. shorter lead times), cultural (e.g. differences between host country and home country management styles), ethical (e.g. host country corruption), etc. This research project attempts to discover if factors like these have influenced the hiring decisions of specific companies in the Upper-Midwestern portion of the U.S. as well, or if they have worked through an entirely different decision framework.
The Role of Natural Products in Acidovorax delafieldii ATH2-2RS/1 Survival in a Dry Formulation
Authors:   ,   Andrews University, Thomas David
Published: June 2023

If rhizobacteria are to be used for weed biocontrol, a practical means of storing them must be found. In this project I sought to use the natural products exopolysaccharide and hydroxygectoine to improve the survival of Acidovorax delafieldii dry formulated with either an oat flour, maltose, and trehalose formulation or Celite (diatomaceous earth). When formulated with the oat flour, maltose, and trehalose, the expolysaccharide allowed for modest survival after 24 hours of drying. Using Celite, a preferred carrier, hydroxyectoine led to bacterial populations of 6.2 x 10(4) cells / g formulation after 24 hours of drying after 48 hours of cold storage.
ПІВДЕННО-ЗАХІДНИЙ ФРОНТ В ПЕРІОД ПЕРШОЇ СВІТОВОЇ ВІЙНИ
Authors: Кравець Анатолій , Казмірчук Олег
Published: June 2023

У статті розглянуто хід бойових дій Південно-Західного фронту на території України. Охарактеризовано наступальну операцію російської армії проти австро-угорських і німецьких військ, яка увійшла в історію під назвою Брусиловського (Луцького) прориву і походить від прізвища генерала О. Брусилова, який командував згаданим фронтом. Найважливіші бойові дії відбулися навесні-влітку, а також восени 1916 року та охопили значну частину української території – зокрема Волинь, Галичину, Буковину та Поділля. Проаналізовано потребу всіх воєнно-історичних подій, які відбувалися на території нашої держави впродовж її історії, зокрема і Першої світової війни. Вони здійснили значний вплив на перебіг бойових дій 1916–1917 років та відчутно вплинули на подальшу розстановку воєнно-політичних сил у Європі. Важливе значення мали операції 1916 року на Східному фронті. Війська мали, згідно з рішенням конференції в Шантіль’ї, у 1916 році здійснити комбінований удар проти Центральних держав на Російському, Італійському і Французькому фронтах. До складу військ Південно-Західного фронту входило 4 армії: 7-ма, командуючий – генерал від інфантерії Д. Щербачов, 8-ма, командуючий – генерал від кавалерії О. Каледін, 9-та, командуючий – генерал від інфантерії П. Лечицький, 11-та, командуючий – генерал від кавалерії В. Сахаров Операція являє собою видатне досягнення воєнного мистецтва. Внаслідок цього прориву фронт був переміщений на 80–120 км вглиб території супротивника. Війська О. Брусилова зайняли майже всю Волинь, Буковину і частину Галичини. Ця операція в ході всієї Першої світової війни отримала назву не за географічною ознакою, а на честь прізвища полководця.
