Verschwendet euch! Die Nicht-Notwendigkeit des Spitzensports in ihrer gesellschaftlich notwendigen Vorbildfunktion verstehen
Authors: Stiller Timo
Published: August 2023

In der Bundesrepublik Deutschland zielt die Verwendung staatlicher Mittel darauf ab, handlungsleitende sowie am Gemeinwohl orientierte Strukturen zu gewährleisten. Somit sieht sich auch die staatliche Förderung des Spitzensports einem Legitimationsdruck ausgesetzt, seinen Zweck für das Allgemeinwohl erklären zu müssen. Inhalt des vorliegenden Beitrags ist es, zunächst die Widersprüchlichkeit darzulegen, in die eine rein erfolgsorientierte Begründung des Spitzensports führt, um dann gerade die Perfektionierung etwas Nicht-Notwendigen als notwendige Vorbildfunktion für eine Zivilgesellschaft zu entfalten. Über die Akzeptanz der Nicht-Notwendigkeit setzt dies jedoch voraus, auch die Unverfügbarkeit als Wesen des Spitzensports anzunehmen. Somit führt die Legitimation des Spitzensports vielmehr zu einer hermeneutischen Herausforderung, das Einzigartige, was uns am meisten berührt, verständlich werden zu lassen, ohne es erklären zu müssen.
Entstehung organisationaler Initiativen zur Integration von Menschen mit Migrationshintergrund in Schweizer Fußballvereinen
Authors: Buser Matthias , Nagel Siegfried
Published: August 2023

Der Beitrag analysiert auf Basis akteurtheoretischer Konzepte und des Papierkorbmodells die Entstehung organisationaler Initiativen zur Einbindung von Menschen mit Migrationshintergrund in Fußballvereinen. Als empirische Grundlage dienen 32 Expert:inneninterviews im Rahmen von Fallstudien in 12 Schweizer Fußballvereinen, welche organisationale Initiativen ergriffen haben. Die Ergebnisse zeigen, dass viele Vereine auf Basis moralischer Überzeugungen auf externe Anfragen im Zusammenhang mit den Fluchtbewegungen ab 2015 reagieren und zunächst Fußballangebote und bei gewichtigen Herausforderungen in der Umsetzung teilweise weitere strukturelle Maßnahmen realisieren. In der Regel sind dabei einzelne Vorstandsmitglieder aktiv, welche das Thema meist in informellen Entscheidungsgelegenheiten verhandeln. Nicht immer werden die Interessen unbeteiligter Mitglieder dabei berücksichtigt. Das Papierkorbmodell erweist sich als geeigneter theoretisch-methodischer Analyserahmen zur Untersuchung organisationaler Prozesse im Kontext der Integration in Sportvereinen.
EXPLORING THE EXPERIENCES OF SOCIAL WORK STUDENTS ON THE USE OF BLENDED LEARNING AND EMERGENCY REMOTE ONLINE LEARNING PRIOR TO AND DURING COVID-19 PANDEMIC
Authors: Makhanya Thembelihle Brenda , Mfishi Zwelisha
Published: August 2023

The study employed a qualitative research approach and emancipatory framework to explore students’ experiences with blended learning and emergency remote online learning (EROL). Two data sets were collected from two projects using focus group discussions and semi-structured individual interviews. The findings highlighted that although technological advancement in universities increased access to information, the needs of the disadvantaged students remain overlooked. EROL and/or blended learning adopted by the universities did not address the fundamentals of access to teaching and learning for the disadvantaged, but focused on institutional needs and saving the academic year. The utilisation of blended learning prior to COVID-19 was excluding some students, and it was unclear how EROL was transformed to ensure that all students accessed education during COVID-19 induced lockdowns. There is thus a need for research to focus on opportunities for student technological advancement not only for ensuring access to education but also for meaningful service delivery during practice. Keywords: blended learning, COVID-19, online learning, social work and students

Authors: Anderson Kristyn , Carrea Cecilia , Gagnon Charlene , Hopson Jenna , Kirk Sara F.L. , Pavey Lila , Siritsky N
Published: August 2023

Childhood lays the foundations for lifelong health and well-being. Children and youth have a fundamental right to have their needs met and to have their health and well-being considered a priority. Nova Scotia is one of the last provinces in Canada to create an independent body focused on asserting and protecting children’s rights. At present, legislation in support of an independent Child and Youth Commission (CYC) is being considered to monitor child rights and engage young people in conversations about the things that matter to them. On November 18, 2022, and in recognition of National Child Day, a “Fishbowl Conversation” panel presentation was convened, with the panel held in-person at Dalhousie University and an audience participating online. The panel engaged in a critical conversation about ongoing work in Nova Scotia aimed at addressing child rights and well-being, for the purpose of guiding the work of a CYC. This commentary article summarizes the recommendations from this panel, unifying the work from various reports and initiatives addressing child rights in the province.

Structure of the system of information support for small business structures
Authors:   Odessa National Polytechnic University, Antoshchuk Vitalii
Published: August 2023

The article analyzes the organization of information support of small business structures (SBS). The importance of information support in making management decisions is shown. The definition of the concept of information support and the definition of its requirements are given. It is proposed to present information support of small business structures in four interrelated levels: with dynamic information with high rate of change, which requires constant monitoring (information on the external environment and operational management) and quasi-static information (on the organization of internal activities). The main obstacles that complicate their information support are given. It is shown that a significant contribution to the creation of information support of SBS is the application of the concept of collective intelligence to identify both problem areas in the activities of SBS and to identify alternatives to support the search and management decisions. The proposed solutions were tested at one of the small enterprises in Odessa and showed positive results.

Authors:   Odessa National Ploytechnic University, Zakharchenko Vitaliy , Bondarenko Kateryna ,   Odessa National Polytechnic University
Published: August 2023

On the basis of economic and mathematical modeling, an initial assessment of the functioning reliability of an industrial enterprise management system is proposed. The reliability concept of the control system includes faultlessness, that is, timely error-free execution of management operations and the process correlation of untimely execution of technological operations is possible. It is believed that in the control system at each moment of time the input elements of the technology are performed independently of each other. Similarly, management operations are also performed independently of each other, and their failure to perform is accidental. Management operations are combined into separate groups of technology elements. It is believed that the errors correction occurs simultaneously with other management operations implementation and the corresponding elements functioning of management technology. There also were analyzed three main management models – target, functional, linear – which in practice are usually found as their synthesis.

Published: August 2023

Approaches to modeling the socio-ecological-economic effect based on the example of the sphere of health-improving nature management are considered, which is considered from three positions: as a phenomenon, process and type of activity and in which there is no clear causal link between measures, ecological state and results . Socio-ecological and economic efficiency is considered as a relative change in the entropy of the system "nature-humanity" due to the implementation of the project under the influence of three groups of factors: the number of incurable; the level of contamination of the territory; technogenic load on the ecosystem. This approach can be considered universal and used in all spheres and not only nature management but in general where there is no clear set of predictor variables and their values are unknown.

Published: August 2023

This study aims to address the issue of the use of modern technology as a mechanism that would protect child victims and witnesses of crime, by shedding light on the definitions associated with the study, the legal regulation of the use of these means with child victims and witnesses of crime, the legal scope of using these means, and talking about the procedures to be taken. The study followed the analytical approach to the legal provisions of the legislation under study. The study reached a set of results, including that electronic means are an effective means to remove the child victim or witness of crime from the atmosphere of the courtroom and reduce his tension by avoiding him confronting the offender, and to provide an appropriate environment that enables the victim or witness of crime to focus on questions and answer them in a comfortable environment. It enables him to provide better and clearer testimony, and the position of the Jordanian legislator came to explicitly stipulate the use of electronic means to protect child victims and witnesses of crime in investigation and criminal trial procedures, taking into account the guidelines adopted by the United Nations in the field of child witness and victim protection, as the legislator took into account When organizing the legal provisions for the use of electronic means, the Jordanian legal guarantees the validity of the investigation and criminal trial with children. Through the means of audio-visual communication, it became possible to direct interactive communication with sound and image without physical movement between children who are spatially separated from the court, and this is an achievement of the principle of presence, oral and public. It also concluded with a number of recommendations, including amending the legal provision that makes the use of electronic means to protect child victims and witnesses of crime permissible for the court to be obligatory in all investigation and criminal trial procedures as long as the legal guarantees for trials are observed, and to find a kind of continuous coordination and cooperation with the leading countries. To develop working methods in the courts, to achieve speedy justice, and to better serve children who are victims and witnesses of crime. Perhaps this study contributes to identifying the limits reached by the State of Jordan in terms of legislative and procedural interest in electronic means and its use to protect child victims and witnesses of crime.

Escrever um prefácio é uma difícil tarefa e um ato de agradecimento pela possibilidade de ler, em primeira mão, uma obra inédita, entregue a este leitor privilegiado pelos autores, num ato de confiança. Ao receber o convite para avistar a tela em branco, na qual há um texto a escrever, emerge sempre a pergunta pela escolha, pelo melhor caminho a seguir. Há certa praxe na escrita de prefácios, que aponta para um eventual percurso pelos capítulos e dos quais se espera uma breve apresentação e destaques da leitura do prefaciador. No entanto, estamos aqui perante um livro que se inscreve no campo da psicanálise, mais especificamente da pesquisa psicanalítica e, assim, fiéis ao método aprendido nas situações de tratamento e investigação, abre-se a possibilidade de produzir alguns desvios.
NARRATIVAS MEMORIALÍSTICAS: POR UMA JUSTIFICAÇÃO FILOSÓFICA
Authors: Roberto Drawin Carlos
Published: August 2023

A expressão “narrativas memorialísticas” é de fácil compreensão, e, por conseguinte, pode parecer inusitada a pretensão de oferecer justificação filosófica a um significado aparentemente bem simples. Afinal, “narrar” é contar uma história e criar um enredo mais ou menos linear e banal, e, ao predicar a narração como “memorialística”, parece ser óbvio se tratar de algo relativo à recordação, e todos nós fazemos isso ao contarmos, todos os dias, uns aos outros, o que se sucedeu conosco em nossos afazeres e circunstâncias. Quando, no entanto, atribuímos às “narrativas memorialísticas” o estatuto de um método, a simplicidade do significado inicial pode ser justamente o elemento perturbador. A etimologia do termo “método” é bem conhecida, pois provém da palavra “caminho” (hodós), e um caminho ou itinerário é uma estrada (iter) que nos leva de um lugar a outro; por isso, segui-lo supõe possuir certo objetivo ou finalidade. Se já estamos onde queremos estar ou se nada sabemos sobre onde queremos ir, então não saímos do lugar ou, simplesmente, andamos em volta, mais ou menos perdidos. Mas, mesmo nesse caso, o objetivo está posto, embora permaneçamos parados ou andando sem rumo. Há sempre um objetivo explícito ou pressuposto, e a possível dificuldade se encontra em determinar qual trajeto devemos tomar para atingi-lo.

On global extrema of power Takagi functions
Authors: Galkin Oleg E. , Galkina Svetlana Yu. , Tronov Anton A.
Published: August 2023

By construction, power Takagi functions Sp
are similar to Takagi's continuous nowhere differentiable function described in 1903. These real-valued functions Sp(x)
have one real parameter p>0
. They are defined on the real axis R
by the series Sp(x)=∑∞n=0(S0(2nx)/2n)p
, where S0(x)
is the distance from real number x
to the nearest integer number. We show that for every p>0
, the functions Sp
are everywhere continuous, but nowhere differentiable on R
. Next, we derive functional equations for Takagi power functions. With these, it is possible, in particular, to calculate the values Sp(x)
at rational points x
. In addition, for all values of the parameter p
from the interval (0;1)
, we find the global extrema of the functions Sp
, as well as the points where they are reached. It turns out that the global maximum of Sp
equals to 2p/(3p(2p−1))
and is reached only at points q+1/3
and q+2/3
, where q
is an arbitrary integer. The global minimum of the functions Sp
equals to 0
and is reached only at integer points. Using the results on global extremes, we obtain two-sided estimates for the functions Sp
and find the points at which these estimates are reached.
Az aminosav-pozitronemissziós tomográfiás mérések klinikai jelentősége a primer rosszindulatú agydaganatok kezelésében

Published: August 2023

Az utóbbi évek nagymértékű diagnosztikai és terápiás fejlődésének ellenére a
felnőttkori primer malignus agydaganatok heterogenitása és terápiás vezetése
jelentős kihívás elé állítja a kezelőorvost. Az elmúlt két évtizedben
felhalmozódott kutatás és tapasztalat alapján körvonalazódott azon betegek köre,
akik a legtöbbet profitálhatnak a komplex onkológiai kezelésből, és megerősítést
nyert, hogy az adekvát terápiás vezetéshez elengedhetetlen a megbízható komplex
diagnosztikai háttér. Mindazonáltal – egyes szükséges terápiás lépéseket
követően – az „arany standard” mágneses rezonancia (MR) nem képes minden esetben
a posztterápiás állapotok pontos megítélésére, diagnosztizálására. A nukleáris
medicina és a neuroonkológiai szakmák kollaborációjának köszönhetően ma már
egyre több centrumban egyre többféle nyomjelző vegyület érhető el, beleértve az
aminosavtrészereket és ezáltal az O-(2-[18F]fluor-etil)-L-tirozin
radiofarmakonnal végzett pozitronemissziós tomográfiás (PET-) vizsgálatokat. A
metabolikus állapot, mint a képalkotás egyfajta negyedik dimenziója, az adekvát
modern diagnosztika elengedhetetlen része. A fejlett MR-technikák és a PET-alapú
(PET/CT, PET/MR) mérések megfelelő nyomjelzővel való kombinálása képes
megbízható alapokra helyezni a terápiás döntéseket. A módszer hazai és külföldi
gyakorlatának irodalmi áttekintésével és az eddigi retrospektív összegző
kutatásunk eredményeinek ismertetésével mutatjuk be az aminosav-PET-alapú hibrid

Homograftok használata érsebészeti fertőzésekben
Authors: Garbaisz Dávid , Szeberin Zoltán , Hidi László , Sótonyi Péter
Published: August 2023

Az érsebészeti graftinfekciók és a fertőzött szöveti környezetben végzett
érrekonstrukciók is jelentős morbiditással és mortalitással járó állapotok,
melyek komoly kihívást jelentenek az operáló érsebész számára. A szeptikus
érsebészetben nincs egységes álláspont sem az operatív stratégiát, sem az
érpótlásra használt graft anyagát illetően. Az ajánlások alapján az elsőként
választandó a beteg saját szervezetéből származó, ún. autológ graft használata,
azonban ennek hiánya vagy alkalmatlansága esetén ígéretes lehet a szervdonorból
explantált, ún. homograft alkalmazása. Célunk az elmúlt 7 év során megjelent,
érsebészeti szeptikus kórállapotokban felhasznált homograftokkal foglalkozó
szakirodalmi közlemények áttekintése volt. Az adatgyűjtés a 2016. január 1. és
2022. december 31. közötti időszakot áttekintve történt. A PubMed és Medline
adatbázisokban szisztematikus keresés során az érsebészeti szeptikus
kórállapotokban alkalmazott, krioprezervált homograft beültetésének
eredményeiről beszámoló közleményeket választottuk ki és elemeztük. A
publikációk eredményeinek elemzése a következő végpontok alapján történt: a
vizsgálat jellege, demográfiai adatok, mortalitási arány, a grafthoz köthető
szövődmények és a reoperáció aránya, a graft nyitva maradása, végtagmentési
arány, graft-újrafertőződési arány és túlélési arány. A szisztematikus keresést
követően 16 közlemény adatait dolgoztuk fel. A publikációkat két csoportra
osztottuk: aortán végzett érműtétek (aorta) és perifériás ereken végzett
érműtétek (perifériás). Az aortacsoportba 12 közlemény került, melyek 542 beteg
adatait dolgozták fel. A korai halálozási arány (<30 nap) 2,8% és 42,8%
közötti, a homografttal kapcsolatos reoperációs arány 5,9% és 29% közötti, míg a
graft-újrafertőződési arány 10% alatti volt. A perifériás csoportba 4 vizsgálat
került, amelyek 252 beteg adatait fedik le. A korai halálozási arány (<30
nap) 2,0% és 38% közötti, az allografttal kapcsolatos reoperációs arány 4,0% és
55% közötti (korai és késői), míg a graft-újrafertőződési arány 4% körüli volt.
Összefoglaló közleményünk adatai alapján az érsebészeti fertőzések során
felhasznált homograftokkal végzett beavatkozások mortalitása és reoperációs
aránya nem ítélhető meg egyértelműen, azonban az alacsony újrafertőződési
arányból és az előnyös biológiai tulajdonságokból adódóan megfelelő választás
lehet érrekonstrukciók során. Orv Hetil. 2023; 164(32): 1256–1262.
Inverse problem for differential systems having a singularity and turning point of even or odd order
Authors: MOSAZADEH Seyfollah
Published: August 2023

In this paper, the canonical property of the solutions and the inverse problem for a system of differential equations having a singularity and turning point of even or odd order are investigated. First, we study the infinite product representation of the solutions of the system in turning case, and derive the corresponding dual equations. Then, by a replacement, we transform the system of differential equations to a second-order differential equation with a singularity and find the canonical product representation of its solution, and provide a procedure for constructing the solution of the inverse problem. We present a new approach to solve the inverse problems having a singularity inside the interval.

Published: August 2023

In this paper, we make use of generalized derivations to scrutinize the deportment of prime ideal satisfying certain algebraic $*$-identities in rings with involution. In specific cases, the structure of the quotient ring $\mathscr{R}/\mathscr{P}$ will be resolved, where $\mathscr{R}$ is an arbitrary ring and $\mathscr{P}$ is a prime ideal of $\mathscr{R}$ and we also find the behaviour of derivations associated with generalized derivations satisfying algebraic $*$-identities involving prime ideals. Finally, we conclude our paper with applications of the previous section's results.

We also give a characterization for the generalized weighted $B$-Morrey spaces via the boundedness of the Riesz potential and its commutators generated by generalized translate operators associated with Laplace-Bessel differential operator.

Authors: Gözütok Uğur
Published: August 2023

We present a new and efficient algorithm to compute affine equivalences and symmetries between two trigonometric curves in an arbitrary dimension. The algorithm benefits from the power of invariance and polynomial gcd and factoring without solving any system of equations. The algorithm is implemented in MAPLE, and extensive experimentations demonstrating the efficiency of the method are given.
Classification and Object Detection on Satellite Images Using Custom CNN Architecture
Authors: A N Sunitha , M N Susmitha
Published: August 2023

As the variety of applications for satellite image analysis growing, some of these applications include surveillance, military operations, geospatial research, and environmental impact and climate change monitoring. One of the most important aspects of satellite image analysis is the capacity to automatically recognise and classify objects. Recognizing and classifying items in aviation images may be challenging due to the type and size of the objects as well as the shifting visual features. Because of the type and information included in these photographs, manual article location is quite laborious. It is appealing to automate the finding of various highlights or articles from these satellite photos. The conventional techniques for categorising things include two steps: I identifying the areas of the image where objects are present, and (ii) categorising the items in those areas. It's harder to recognise items because of the complicated background, size, noise, and distance features. According to this research, a specially created convolutional neural network may be used to recognise and classify three distinct objects in the photographs, including trees, buildings, and cars. Also, it aims to grasp and briefly sum up the performance characteristics of the fictitious custom CNN.

The likelihood of fire following a natural or man-made event is comparatively high, such as a fire occurring after a terrorist attack or any natural disaster such as a tornado, lightning strike or earthquake. A structure is the one element that is consistent throughout all these different hazard–fire interactions. In this work, the response of a three-dimensional monolithic reinforced concrete (RC) dome structure under explosion loading followed by a fire event was analysed using detailed finite-element (FE) analysis in LS-Dyna. The analysis was divided into three stages. Since an explosion is a dynamic event and gravity loads and fire are considered quasi-static events, explicit and implicit solvers were alternately employed. Material data and equations governing the thermal and non-linear behaviour of RC structures from BS EN 1992-1-2:2004 were used. A blast load was applied to the dome structure through Load_Blast_Enhanced in LS-Dyna. Fire load was applied as per ISO 834-10:2014. The results showed that an explosion followed by fire significantly increases structural damage. The major aim of this work was to understand the behaviour of a dome structure under combined blast and fire loading and to show the capabilities of FE analyses in such investigations.

Predicting open stope performance at an octree resolution using multivariate models

Published: August 2023

Open stoping has become a popular mining method in hard rock mines, not only due to the safety of the method as a non-entry approach, but also because of the high extraction rate and low costs. At mine sites, stope performance is evaluated by calculating stope overbreak using the stability chart. However, limitations of the stability chart regarding the precision of the predictions, non-consideration of factors such as the influence of blasting, and the exclusion of underbreak have led to non-optimal designs. The capabilities of today's computers have increased the amount of data being collected and the power of models being built. This article presents a step towards a new stope design approach where stope overbreak and underbreak are measured and georeferenced using octrees at an approximately cubic metre resolution and predicted using multivariate statistical models (partial least square, linear discriminant analysis, and random forest). Results show that overbreak and underbreak location along the design surface and their magnitude are predicted with good precision using a random forest model. These predictions are used to build the expected geometry of the open stope. The resolution of the data and the use of multivariate analysis has enabled the prediction of variation in stope performance along the design surface, going well beyond the simple qualitative per stope face prediction provided by a traditional stability chart approach. Keywords: stope design, stope reconciliation, overbreak, underbreak, multivariate, prediction, random forest.
Returning to the Philosophical Comprehension of the Phenomenon of Post-Truth

Published: August 2023

The subject of the study is the phenomenon of post-truth (reflective post-truth and valuative post-truth), considered from the perspective of philosophical methodology, for which the authors turn to the definition of this phenomenon and the analysis of its essence. The article indicates the difficulties that the very construction of this term causes. In addition, the indistinguishability of the notions ‘reflective truth’ and ‘valuative truth’ leads to incorrect translations of the term ‘post-truth’ into Russian. The authors of the article believe that the term ‘post-truth’ can be translated as ‘reflective post-truth’ and applied to reflective knowledge, revealing objects in their own logic of development, and as ‘valuative post-truth’ – in relation to value knowledge, revealing an axiological approach to the world. The analysis of the use of the term ‘post-truth’ has shown that there are at least three approaches: in a negative connotation, as a state of society in which the universally valid truth (objective truth) has ‘disappeared’, everyone interprets it in their own way, although ‘their’ interpretation is, in fact, an imposed interpretation; in a positive connotation, when in a state of post-truth, the truth is not denied, but it is stated that it has changed the form of its existence, dissolving into partial truths expressed by numerous subjects; in a neutral connotation, proceeding from the fact that the post-truth has always been, now, due to new information and communication technologies, it has simply become more noticeable. In conclusion, it is concluded that the situation of post-truth has created new conditions for the development of reflective knowledge, primarily due to the ‘democratization of science’, as well as value knowledge – including through the processes of self-communication. But the results obtained must be critically rethought. This means that it is necessary to return once again to the established rules of the game, analyze them from the perspective of possible risks, and take measures to prevent them. To this should be added the need to develop critical thinking, including among a wide audience of social networks.
Dialectical View on Disturbed Harmony in the First World War Letters of German Students in 1914-1918
Authors:   Saint-Petersburg State University, Russian Federation, Trendelkamp Tim
Published: August 2023

In this article the collection of letters written by voluntary students during the First World War is analyzed from a philosophical point of view. The collection was assembled by Philipp Witkop during the years of the First World War and after it. The author of the article analyzes two philosophical tendencies of materialism and idealism, which appear in the letters. These two philosophical tendencies are considered as phenomena of well-ordered life in peaceful times. The main material of this research is the original text of the collection of letters, as compiled by Philipp Witkop. Then, the texts of Clausewitz, Scheler, Heidegger and Ernst Jünger were added to further enrich the scope of the study. To assess the genuinity and political meaning of the compilation of letters, the author consulted with the contemporary researchers and their results. The main method of this study is the method of reading the text, conducting conceptual analysis and then attempting to develop a philosophical scheme in order to create a senseful context of what was read. Finally, the attempt is made to reunify the contradictions which were discovered as a result of the textual analysis. This attempt of reunification of the discovered contradictions is called the dialectical synthesis. Thus, the dialectical method is one of the important methods employed during the course of this study. The phenomenon of war could be successfully defined as a phenomenon of the destruction of the harmony of usual, peaceful order of life in a state. The author comes to the conclusion that the content of the letters can be mainly divided in two subgroups. The first subgroup is the subgroup of Idealism. Roughly speaking, these are the students who are enthusiastic about the participation in the war. They have an intellectual tendency towards collectivism. The second subgroup is the subgroup of materialism. This is the subgroup of those students who do not approve of the war. The mindset of these students can be called individualistic. Finally, some letters which attempt to create a dialectical synthesis of these two tendencies could be identified. This dialectical synthesis overcomes the fear of death. But it does not abandon the value of the individual conciousness and the individual personality. The discovery of the dialectical syntheses gives the prove that there can be a more complex attitude towards the historical phenomenon of war as a destructor of well-ordered harmony. It is possible not only to be afraid of death and miss the peaceful times, but also to radically welcome the new times of war. The author highlights the complexity of the human being. But at the same time, the author offers an argument for the possibility to create a senseful philosophical scheme to make sense of the complex properties of the human experience.
