Published: September 2023

Objectives This study explored the understanding of the IB program, the application of the national curriculum, the implementation of unit design, and the teachers' perceptions and experiences of conducting actual classes and evaluations, targeting IB MYP World School 3 teachers introduced into public education. And the purpose of this study is to reveal the possibility of spreading IB education and implications for the tasks.
Methods To this end, data were collected, analyzed, and organized through focus group interviews with 10 IB MYP World School 3 teachers in A region.
Results IB MYP World School teachers were making efforts to understand and apply the IB program from various angles, and as a result of data analysis, four themes were presented. First, after the introduction of the IB MYP program, changes in curriculum literacy and teaching and evaluation through teacher curriculum restructuring, class and evaluation design were summarized. Second, the aspects of teacher development and learning after experiencing the IB program at the IB MYP World School were described. Third, I looked at what teacher growth is through collaboration with fellow teachers to understand and apply the IB program, personal growth experience, and online and offline IB training experience. Lastly, since the IB MYP is not an easy program to understand and implement, I looked at the practical difficulties experienced by IB school teachers and the prerequisite tasks for the establishment and spread of the IB program in public education.
Conclusions Therefore, through the IB MYP World School teachers' experience of implementing the IB program, teacher professionalism and identity were discussed. For the establishment of IB education, suggestions were made on the spread of consensus among the educational community, institutional supplementation of teacher assignment, and changes in the teacher training system.
The meaning of young children's participatory displays on the wall as a classroom space: Making displays of the rainbow tree on the wall together
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kang Jinju
Published: September 2023

Objectives The purpose of this study is to find out the process and educational meaning of young children’s participatory displays on the wall as a classroom space.
Methods To this end, from the beginning of September 2019 to the end of February 2020, the 4-year-old class was observed twice a week, and a teacher and children were interviewed, and collection of artifacts were conducted. The collected data was analyzed using the thematic analysis method, taking the content of the participatory wall display for young children suggested by Kang, Jinju and Goh, Eun Kyoung (2022) as an interpretive framework.
Results As a result of this study, the tree display, ‘rainbow tree’ named by children and their parents was put in seven different shapes on the wall of the class for 6 months. The process and meaning of the wall display: First, as breaking the space boundary, the rainbow tree changed its appearance in various ways, and a wall display changed the space of our class. Second, as breaking the time boundary, the current interest of our class was revealed, and a wall display was made in which our stories with serendipity were continuously made. Fourth, as breaking the boundaries of authority, the children's participation became more diverse and the wall displays were made to tell our authentic stories.
Conclusions It was discussed that the young children’s participatory wall display constituted the narrative of young children and was a child-centered educational experience in which children could actively participate in learning, which the wall can be a meaningful space within the classroom as a place for playing and documenting at the same time.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Oh Youngyoul
Published: September 2023

Objectives The purpose of this study is to provide implications for the challenges and future directions of mathematics education in Korea in the post-COVID-19 era, based on the analysis of online education conducted during the COVID-19 pandemic.
Methods To this end, domestic and foreign academic papers on the characteristics of mathematics classes in online education conducted during the COVID-19 pandemic, the impact of online education on students' mathematics learning, and the inequity of online mathematics learning and the use of technology in mathematics education are the main targets of literature analysis.
Results It has been revealed that online education has reduced students' achievement in mathematics and deepened the polarization of mathematics learning among students. In particular, the decline in mathematics achievement of students in the lower achievement level was serious, and the cause was found to be because the online class environment made it difficult to receive help from teachers and required self-directed learning ability. In addition, online education has led to a deepening of the polarization of mathematics learning among students by acting as an unequal learning environment for students with insufficient mathematics learning capabilities or from underprivileged families to learn mathematics.
Conclusions It is necessary to seek active use of technology as a way to alleviate the problem of learning polarization caused by the decline in mathematics achievement and learning inequity revealed in online education and to change mathematics education. To this end, it is necessary to develop and share a vision for mathematics classes using technology.

understanding of Dokdo issues into the past, present, future, insight of Dokdo issues into the past, present,
future, practice of Dokdo issues into the past, present, future in terms of educational goals, Dokdo related learning
from the environmental, economic, social levels, Dokdo integrated learning from the environmental, economic,
social levels in terms of learning contents, discussion activities for decision making, project learning for problem
solving in terms of education methods, and building a school community linking university and middle school,
building a local community linking university and local community in terms of educational infrastructure.
Conclusions This study suggests the development of a Dokdo education model that reflects the characteristics
of teacher training institutions, the development of Dokdo education standard curriculum in teacher training institutions,
the operation of Dokdo education centered on pre-service teachers in teacher training institutions, and
the support of the human and material resources for Dokdo education in teacher training institutions.
A Case Study of a Constructivist Class for the Development of Multicultural Education Competency of Pre-service Early Childhood Teachers
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Han Heekyung
Published: September 2023

Objectives The purposes of this case study were to qualitatively examine the class process and results applied
with the constructivist teaching and learning method to foster multicultural education competency of pre-service
early childhood teachers and to provide basic data for exploring multicultural education curricula in the teacher
training institution.
Methods The participants were 24 sophomores who took the multicultural education class held in the first semester
of 2022 at the department of early childhood education at a four-year university in the Chungcheon region.
Research data were collected through e-campus postings, discussion activity reports, reflection journals, multicultural
education contents, peer- and self-evaluation reports, and group interview. The data were analyzed as
suggested by Miles and Huberman(1984).
Results The multicultural education competencies cultivated by pre-service early childhood teachers though a
class applied with the constructivist approach were divided into knowledge, skills, values and attitudes as follows.
First, pre-service early childhood teachers acquired knowledge about individual and social prejudices and the
concept of multiculturalism. Second, they acquired skills to collect and produce and to evaluate multicultural educational
materials. Lastly, they cultivated an attitude of respecting and accepting various viewpoints and a sense
of multicultural teaching efficacy.
Conclusions These results suggest that the constructivist class emphasizing learner’s autonomy and initiative
was effective to foster pre-service early childhood teachers' multicultural education competencies and that various
opportunities are needed from the teacher training process to practice desirable multicultural education in the
field. Based on this case, the direction of multicultural teacher education was discussed in the teacher training
institution.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, HAN HAE-YOUNG , JO HAN-IK
Published: September 2023

Objectives This study aimed to investigate the effects of a VR natural meditation program, combining Seon meditation and innovative VR technology, on positive thinking, social psychological stress, and social concern among university students who experienced stress and emotional exhaustion due to social distancing measures.
Methods An experimental study was conducted on 34 university students who had undergone a complete suspension of school for more than one semester as a result of social distancing measures. The control group did not receive any intervention, while the experimental group participated in a VR natural meditation program consisting of four sessions over a two-week period. To evaluate the program's effectiveness, positive thinking, social psychological stress, and social concern were assessed in both groups, and the results were compared and analyzed using covariance analysis (ANCOVA).
Results The study reports some significant findings. Firstly, the experimental group demonstrated a notable increase in positive thinking following the VR natural meditation experience. In addition, the levels of social psychological stress and social concern significantly decreased among the participants. In their self-evaluation reports after undergoing the VR treatment, the participants reported enhanced focus, strengthened coping skills, increased confidence in managing daily challenges, and a more positive outlook towards uncertain situations instead of being negatively overwhelmed by their consequences.
Conclusions These results suggest that the SEONMEDI VR Natural Meditation Program holds potential as an intervention to promote the psychological well-being of university students who have faced social disconnection and emotional exhaustion caused by social disasters.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kwon Ohyoung
Published: September 2023

Objectives This study aimed to explore how Meister High School's curriculum affects students' employment and job capabilities and how to effectively enhance the curriculum that improves students' employment and job competency.
Methods Data were collected from the analysis of semi-structured and in-depth interviews with 50 A Meister High School graduates. Data conducted a qualitative case study. A preliminary study was conducted on five people to modify the questionnaire and allocate appropriate interview time. Then, the remaining 45 people were interviewed to collect data that met the purpose of the study. The data analysis procedure applied an analysis method consisting of five stages of a qualitative case study proposed by Creswell (2018). Data collection and analysis procedures followed the Research Ethics Review Committee procedures to secure research ethics.
Results As a result of the analysis, the core contents could be summarized into nine topics derived from three categories and three categories revealed as curriculum, creative experience activities, and other related matters. The nine themes include 1) general subjects that need to be reorganized based on practice; 2) specialized subjects that require segmentation according to the occupational group; 3) autonomous activities that should be utilized to improve employment and job competency; 4) c lub activities that help improve cooperation and communication skills; 5) volunteer activities that require student-specific connections; 6) career activities that desperately need to strengthen field and experience-oriented programs; 7) teacher competency that has the greatest impact on job guidance and job competency enhancement; 8) employment guidance method that considers improving the quality of employment rather than the employment rate; 9) development and expansion of personality and social skills programs.
Conclusions Graduates recognized and experienced that the Meister High School curriculum had an effect on promoting employment and job competency in nine themes based on three categories. However, it was pointed out that the curriculum needs improvement in nine themes to enhance employment and job competency based on focusing on the employment rate. This study explored the case of A Meister High School. Still, given the similarities in the purpose and characteristics of the establishment of 53 Meister High Schools nationwide, it could provide several insights and implications to other Meister High Schools.

Psychological burnout and job satisfaction were negatively correlated. The direct effect of positive psychological capital on job satisfaction was not significant, but the indirect effect through psychological burnout was found to be significant. Therefore, psychological burnout showed a full mediating effect in the relationship between positive psychological capital and job satisfaction.
Conclusions Based on the full mediating effect of psychological burnout in the relationship between positive psychological capital and job satisfaction of professional school counselors, it is suggested that it is effective to intervene with a focus on psychological burnout, in order to improve the job satisfaction of professional school counselors.
The Relationship between COVID-19 related Stressors and Career Anxiety in College Students: The Mediating Effect of Work Volition and The Moderating Effect of Intolerance of Uncertainty
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Byun Yuna , Lee Soojung , Yon Kyu Jin
Published: September 2023

Objectives The purpose of this study was to empirically investigate the mediating effect of the sub-factors of work volition, volition and constraints and the moderating effect of intolerance of uncertainty in the relationship between COVID-19 stressors and career anxiety.
Methods 288 college students aged 19 to 28, who were enrolled in a 4-year university, were surveyed online through the survey company INVIGHT from January 17th to January 20th, 2022, during the fifth wave of the COVID-19 pandemic. Based on the collected data, the parallel multiple mediated effect was examined using Model 4 of PROCESS MACRO 3.5, and the mediating and moderating effects were examined using Model 5.
Results First, the results confirmed a parallel multiple mediated effect of the sub-factors of work volition, volition and constraints, in the relationship between COVID-19 related stressors and career anxiety, indicating that constraints mediated the relationship. However, the mediating effect of volition was not significant. Second, it was found that intolerance of uncertainty moderated the relationship between COVID-19 related stressors and career anxiety.
Conclusions As Korean college students experience more COVID-19 related stressors, their perception of constraints increases, leading to higher levels of career anxiety. Additionally, higher levels of intolerance of uncertainty intensify the impact of COVID-19 related stressors on career anxiety. Based on findings, the implication of the current finding in counseling practice, limitations of the study, and suggestions for further research were discussed.

Quantum error correction with fractal topological codes
Authors: Dua Arpit , Jochym-O'Connor Tomas , Zhu Guanyu
Published: September 2023

Recently, a class of fractal surface codes (FSCs), has been constructed on fractal lattices with Hausdorff dimension 2+ϵ, which admits a fault-tolerant non-Clifford CCZ gate \cite{zhu2021topological}. We investigate the performance of such FSCs as fault-tolerant quantum memories. We prove that there exist decoding strategies with non-zero thresholds for bit-flip and phase-flip errors in the FSCs with Hausdorff dimension 2+ϵ. For the bit-flip errors, we adapt the sweep decoder, developed for string-like syndromes in the regular 3D surface code, to the FSCs by designing suitable modifications on the boundaries of the holes in the fractal lattice. Our adaptation of the sweep decoder for the FSCs maintains its self-correcting and single-shot nature. For the phase-flip errors, we employ the minimum-weight-perfect-matching (MWPM) decoder for the point-like syndromes. We report a sustainable fault-tolerant threshold (∼1.7%) under phenomenological noise for the sweep decoder and the code capacity threshold (lower bounded by 2.95%) for the MWPM decoder for a particular FSC with Hausdorff dimension DH≈2.966. The latter can be mapped to a lower bound of the critical point of a confinement-Higgs transition on the fractal lattice, which is tunable via the Hausdorff dimension.
Kant and Marburg School
Authors: Semyonov Valeriy Ye.
Published: September 2023

After the completion of I. Kant’s “Copernican” turn in metaphysics, all subsequent European philosophy to one degree or another was under his influence. The purpose of the article is to consider the reception and transformation of the Kantian theoretical philosophy by the Marburg school of neo-Kantianism. It is necessary to analyze the reasons for H. Cohen's and P. Natorp’s interpretation of Kant's criticism. To do this, one should consider (i) internalist and (ii) externalist factors in the formation of the Marburg School. Neo-Kantianism, on the one hand, emerged as a response to materialism, naturalism, and post-Kantian German idealism. In addition, the Marburg School was strongly influenced by the change in the scientific paradigm in mathematical natural science at the end of the 19th century. The justification by the Marburgers of Kant’s a priori doctrine presupposed thematization, first of all, of: a) purity of thought; b) systematic unity of thought and experience; c) the orientation of philosophy to the “fact of science”; d) transcendental method. As a result, the Marburg School interpreted the Kantian concept of the unity of consciousness; abandoned the principle of synthetic (real) unity of consciousness in favor of systematic (logical) unity; substantiated the purity of scientific thinking; put forward the requirement of orientation of philosophy to the “fact of science”; developed the concept of the origin of thinking (Ursprung); abandoned the idea of “givenness” of the subject of knowledge and proved its “assignment”; changed the understanding of the essence and functions of the transcendental method; put forward the concept of thinking as “generation” (“production”); formulated a new understanding a priori. The changes that took place in the 19th century in philosophy, mathematical natural science and mathematical sciences led to a sharp activation of constructivism. It can be concluded that Kant’s epistemological paradigm was realistic constructivism. Pure constructivism became the paradigm of the Marburg School.
Strawson P.F.: From Hume to Kant and Back Again
Authors: Evstigneev Maksim D.
Published: September 2023

P.F. Strawson is one of the most famous Kantian philosophers and interpretators of Kant’s “Critique of Pure Reason”. This study is dedicated to reconstruction of this interpretation. It is also dedicated to the analysis of the story and place of Strawson’s interpretation in the history of his own philosophical career. I show how Strawson reads Kant’s text, what strategies of interpretation he adopts and what problems he faces. In “Individuals” and “The Bounds of Sense” Strawson explicitly associates himself with Kant and considers himself as Kantian philosopher. Kantian philosophy for Strawson is the descriptive, anti-sceptical metaphysics that seeks to explicate our basic conceptual sсheme. However, due to various criticism, Strawson had to abandon descriptive metaphysics and to change his intellectual figures. On of the main heroes of “Skepticism and Naturalism” - his late book - becomes Hume. The second part of the paper is dedicated to the explanation of the transition from Kant to Hume. In this work, Strawson argues for some kind of soft Hume-like naturalism instead of previously held descriptive metaphysics. This kind of naturalism is more modest than metaphysics. It does not pretend to be the main and the most fundamental of all the philosophical studies. It is simply an analysis of one of the possible philosophical perspective. The stand point of ordinary believes.
Kant’s Transcendentalism as Metaphysics of Possible Experience and its Realistic Interpretation in Analytical Philosophy
Authors: Katrechko Sergey L.
Published: September 2023

In the “Critique of Pure Reason” and subsequent “Prolegomena to Any Future Metaphysics...”, “Metaphysical Principles of Natural Science”, “Opus Postumum” Kant develops one of the modes of his transcendentalism, the metaphysics of possible experience, whose task is to study the transcendental conditions for the possibility of our (cognition), which, according to Kant, has a priori character. P. Strawson calls this mode of metaphysics ‘ descriptive metaphysics ’ and connects it with the analyzing the ‘conceptual structure’ of our thinking about the world. The contemporary realistic trend (primarily within the framework of the analytical philosophical tradition) in the interpretation of Kant’s transcendental philosophy is associated with the modern theory of “two aspects” (80s of the 20th century), which replaced the classical theory of “two objects/worlds” (compare also with the opposition “ theory of appearance vs. theory of appearances ”). Within the framework of this theory, the Kantian ‘appearance’ receives an objectified status, it is not our mental representation, but corresponds (as its signs) to really existing things, or Kantian ‘objects of experience’. The article traces the formation of the historical and conceptual background of the ‘ metaphysics of experience ’ (H. Paton's original expression). Historically, the metaphysics of experience inherits the neo-Kantian approach to interpreting Kant's transcendentalism as a ‘theory of experience’ (H. Cohen, E. Cassirer), then it develops in logical positivism/empiricism (H. Reichenbach, R. Carnap; further in post-posivivism: the theory of I. Lakatos and T. Kuhn), analytical philosophy of science (W. Sellars, G. Buchdal, H. Putnam), and at present the metaphysics of experience is developing in a number of contemporary works of an analytical orientation (P. Strawson, K. Ameriks, L. Allais and etc.).
Existential Sources of School Shootings and Columbine
Authors: Baeva Liudmila V.
Published: September 2023

Manifestations of school shooting or ‘columbine’, constituted by armed mass attacks and murders in educational institutions perpetrated by adolescents, have proliferated in recent years. They are marked by their unpredictability, spontaneity and cruelty. This phenomenon has been subject to scholarly examination from various perspectives, enabling the elucidation of its multifarious traits and characteristics as a means of diagnosis and prevention. This study surveys established academic approaches to the study of school shootings (psychological, legal, sociological, semiotic, existential) and delineates their specificity and scope. Drawing on analysis of incidents of school shootings in Russia from 2014-2022, key signs and tendencies in the occurrence of mass attacks on educational institutions are delineated. Adopting existential approaches in philosophy and psychology, notably the works of A. Camus, E. Fromm, M. Boss, V. Frankl and L. Berkowitz, the semantic stages and constituents of school shootings as existential crimes and subsequent suicides are elucidated. The present study aims to identify and characterise the roots and essence of school shootings ('columbine') as an existential crime type, in order to comprehend the semantic motivational origins of school shootings and analyse the ‘boundary situation’ engendering individual destructive rebellion against the world. The nexus between unresolved existential needs and quandaries of the individual and the factors triggering self-destructive personality mechanisms is expounded, whereby the individual enacts an ‘escape’ from reality against the backdrop of media-disseminated aggressiveness and legitimation of violence as a means of overcoming problems and self-presentation. The existential analysis and modelling of school shooters’ actions offered here has enabled conclusions to be drawn regarding potential countermeasures to such crimes.
Judiciary independence: why should ecologists care?
Authors: Keasar Tamar , Coll Moshe , Lubin Yael , Segoli Michal , Nouhuys Saskya van , Wajnberg Eric
Published: September 2023

We discuss the links between political governance systems and ecological
research, education and environmental policy, focusing on the ongoing
radical changes to the judicial systems in Israel. This judicial
revision has already restricted academic freedom and environmental laws,
and has impacted regulatory actions. We are concerned about future
defunding of ecological research and nature conservation programs,
reduced cross-border ecological collaboration, restrictions of academic
teaching of ecology and evolution, a brain drain of ecologists,
weakening enforcement of environmental laws, and increased power to
polluting corporates. Israel’s unique biodiversity, already threatened
by its rapidly growing population and high development pressures, make
these concerns all the more pressing. We believe that weakening judicial
oversight of government actions in other countries is generating similar
threats at a global scale.
The Omicron XBB.1 Variant and its Descendants: Genomic Mutations, Rapid Dissemination and Notable Characteristics

Published: September 2023

The SARS-CoV-2 virus, which is a major threat to human health, has
undergone many mutations during the replication process due to errors in
the replication steps and modifications in the structure of viral
proteins. The XBB variant was identified for the first time in Singapore
in the fall of 2022. It was then detected in other countries, including
the United States, Canada, and the United Kingdom. We study the impact
of sequence changes on Spike protein structure on the subvariants of XBB
with particular attention to the velocity of variant diffusion and virus
activity w.r.t. its diffusion. We examine the structural and functional
distinctions of the variants in 3 different conformations: (i) Spike
glycoprotein in complex with ACE2 (1-up state), (ii) Spike glycoprotein
(closed-1 state) and (iii) S protein (open-1 state). We also estimate
the transmissibility of the affinity binding between Spike proteins and
ACE2. The market binding affinity observed in specific variants raises
questions about the efficacy of current vaccines in controlling the
spread of these variants. This work may be useful in devising strategies
to manage the ongoing COVID-19 pandemic. To stay ahead of the virus
evolution, further research and surveillance should be carried out to
adjust public health measures accordingly.

Authors:   The Convergence Tourism Contents Society, Kang Dae Hoon
Published: September 2023

Purpose The purpose of this study is to identify the changing tourism attributes of tourists during the COVID-19 period and to propose a study between more effective tourism attributes and satisfaction and behavioral intentions from policy and strategic perspectives.
Methods Data were collected for about 1 month from November 14th to December 11th, targeting tourists who visited tourist spots in Gwangju Metropolitan City. A total of 300 copies were distributed, and 294 copies were used for analysis, excluding 6 copies of the questionnaire for insincere responses. For the analysis, the SPSS 22.0 program was used, and multiple regression analysis was performed to verify the hypothesis.
Results First, among tourism attributes, natural environment did not have a significant effect on satisfaction, but festival event and tourism experience had a significant effect on satisfaction. Second, among tourism attributes, natural environment had no significant effect on behavioral intention, but festival event and tourism experience had statistically significant effects. Third, satisfaction had a significant effect on behavioral intention. Fourth, in the relationship between tourism attributes and behavioral intentions, it was found that festival event properties and tourism experientiality had a significant effect on behavioral intentions through satisfaction.
Conclusion This study presents policy implications and practical implications for tourism development and operation by empirically analyzing the relationship between satisfaction and behavioral intention of tourism attributes. However, since the research area and period are limited, future research should be conducted by expanding a wider area and period.

The reaction of copper(II) with HL1?HCl in methanol afforded the polymeric complex [{Cu(?-Cl)2(MeL1-?2N,N?)}n] (1) featuring the methyl ester of L1 (MeL1). With HL2?HCl or HL3?HCl, the dimeric complex [{CuCl(?-Cl)(HL2-?2N,N?)}2] (2) or the mononuclear complex [CuCl2(HL3- ?3N,N?,N??)] (3) were obtained. All complexes exhibited square-pyramidal geometries. In 1, polymeric chains are formed through bridging chlorido ligands without typical hydrogen bonding interaction. Contrarily, the COOH group in 2 is participating in the formation of intermolecular hydrogen bonding forming a supramolecular structure. In 3, intermolecular hydrogen bonding (Cl???H(O)) leads to a 1-D polymeric structure. The copper(II) complex 2 diminished viability of human 8505C, MCF-7, 518A2 and SW-480 cell lines. The tumoricidal effect of 2 was realized mainly through caspase-mediated apoptosis.

Authors: Végvári Zsolt
Published: September 2023

A Honvédelmi és Haderőfejlesztési Program keretében igen sok új, korszerű harcjármű beszerzéséről született döntés, amelynek következtében jelentősen megújul a szárazföldi csapatok eszközállománya. Az új járművek új képességeket is jelentenek, de az új képességek új műszaki problémákat is hoznak magukkal. A korszerű harcjárművek számos olyan fedélzeti eszközzel rendelkeznek, amelyekkel a korábbiak nem voltak felszerelve, és az új berendezések energiaellátása komoly műszaki kihívást jelent. A tanulmány azt vizsgálja, hogy milyen megoldások születtek erre a problémára külföldön, illetve hazánkban a most rendszeresítésre kerülő eszközökben.

Published: September 2023

A mesterséges intelligencia az elmúlt évek során korunk egyik kulcsfontosságú technológiájává nőtte ki magát. Meghatározó, szemléletformáló, életstílusalakító szerepét, valamint fejlődésének dinamikus ütemét jelzi, hogy azon MI-alapú eszközök és rendszerek, amelyek korábban legfeljebb csak a tudományos-fantasztikus irodalomban léteztek futurisztikus képet vetítve elénk, mára válósággá váltak. Ilyenek például az önvezető járművek, vagy akár az emberi kommunikációra alkalmas humanoid robotok. Jelen cikkünkben áttekintjük a mesterséges intelligencia különböző fejlődéstörténeti korszakait, és azok fontosabb állomásait.

Published: September 2023

Az 5. generációs vezetékes és vezeték nélküli hálózatok fejlesztésének kezdeti időszakában indokolt megvizsgálni az IMT-2020 ajánlásaiban megfogalmazott hálózati paraméterek elérését lehetővé tévő műszaki eljárásokat arra az esetre is előkészülve, amikor a műholdas szegmensből érkező jelsorozat feldolgozása is feladatként jelentkezik. E tudományos közleményben az 5. generációs hálózatok űrszegmensre történő kiterjesztésének egyes követelményeit vizsgálom.
Zsélyi Aladár repülőgép-konstruktőr, aviatikus 2. rész
Authors: Druzsin József
Published: September 2023

Blériot 1909 októberi repülőbemutatója Budapesten számos tehetséges mesterembert indított arra, hogy a magyar repülőgépszerkesztők, aviatikusok sorába lépjen. Zsélyi Aladár azon kevés kivételhez tartozott, aki gépészmérnökként vált aviatikussá. Kísérleteit számítások alapján végezte és dokumentálta. Zsélyi korát messze meghaladó konstrukciós tervei alapján csakhamar a világ élvonalába tartozott. Nemcsak sikeres repülőgépszerkesztő, de tehetséges pilóta is volt, aki írásaival megalapozta a magyar repülési tárgyú szakirodalmat. A szerző rövid tanulmányával a magyar aviatika hőskorának kimagasló személyisége előtt tiszteleg.
Az iMUGS PESCO program folytatása Brüsszelben
Authors: Ocskay István
Published: September 2023

A szerző a Magyar Honvédség Modernizációs Intézet szakértőjeként harmadszor vett részt az iMUGS munkacsoport ülésén, valamint az azt követő technikai bemutatón, amelyeket ezúttal a belga Camp Roi Albert katonai gyakorlótéren tartottak. Megállapítása szerint a korábbi három demonstrációhoz képest folyamatosan fejlődnek a vezető nélküli, szárazföldi rendszerek, és egyre bonyolultabbá válnak az eszközökkel végrehajtandó feladatok. A legutóbbi rendezvényen csak egy – azonban bonyolult megoldású –, a járművek rajzási képességét bemutató szcenárió megvalósítására került sor, amely egyben összefoglalta a korábbi, finnországi bemutató ótaeltelt időszak fejlesztéseit.

Published: September 2023

A cikk a 19. század néhány korai torpedóját ismerteti. Louis Brennan a viktoriánus kor egyik legzseniálisabb gépészeti feltalálója volt. A Brennan-torpedót az első megvalósult irányított lövedékként alkalmazták Anglia kikötőinek és haditengerészeti állomásainak védelmére. A fegyver egy egészen egyedi huzalos meghajtó- és vezérlőmechanizmust alkalmazott. Brennan néhány további, meglepő találmánya a pörgettyűvel stabilizált egysínű vasút, és az első gyrocopter.
A Hofherr gyár a hadsereg szolgálatában
Authors: Farkas Zoltán
Published: September 2023

Hofherr Mátyás 1869-ben „M. Hofherr” néven Bécsben hozta létre önálló cégét, amely mezőgazdasági gépek gyártását végezte. Egyévtizeddel később az angol Clayton gyár egyes részlegeinek megvételével létre jött a Hofherr-Schrantz-Clayton-Shuttleworth Magyar Gépgyári Művek Rt. Az I. világháború idején a hadsereg különböző igényeinek kielégítése, a hadianyag-ellátás biztosítása érdekében a gyár bekapcsolódott a hadianyaggyártásba, és a megrendeléseknek megfelelően különféle szállítóeszközöket, felszereléseket gyártottak. A szerző tanulmányában időrendben végigköveti és bemutatja az üzem legjelentősebb fejlesztéseit. Kitér a II. világháború korszakára, valamint az államosítás utáni időszakra is.
Oroszország A2/AD képességei 3. rész
Authors: Kiss Roland
Published: September 2023

A szerző véleménye szerint Oroszország rendelkezik a Nyugat által A2/AD tárgykörbe sorolt képességekkel, azonban erre vonatkozóstratégiával nem. Sok elemző gyakran félreérti magukat a képességeket, mivel azok valószínűleg elsősorban védelmi jellegűek, és céljuk az ország elleni stratégiai támadások hatásának csökkentése, és nem „buborékok” kialakítása területzárásra.
A személyrepülőgépek biztonsága 1. rész
Authors: Rohács József
Published: September 2023

A személygépjárművek módjára használható személyrepülőgépek, a személyes légi forgalom megvalósulása a jövő nagyszerű lehetősége. A feltételek megteremtéséhez nemcsak a technikai hátteret kell megteremteni, de új elveket kell alkotni, mivel a jövő repülőgép-vezetőinek többségében csak limitált repülési gyakorlata lesz. Az új elvek egyik fontos eleme a repülőgép-vezetők szubjektív döntési mechanizmusának elemzése és a szubjektív döntések modellezése. A tanulmány szerzője a repülőgépek vezetését aktív, endogén, szubjektív rendszernek tekinti, és ebből kiindulva elemzi a kisrepülőgépek biztonságát. Az eredményeket a kisrepülőgépek biztonságfilozófiájának kidolgozásakor mindenképpen érdemes figyelembe venni. A tanulmány három fő kérdéskört vizsgálva először a repülőgép irányítását, majd az irányítás szubjektív analízisét ismerteti, végül a vázolt elvek alapján elemzi egy repülőgép leszállását.
