Authors: Batrakov D.O. , Palamarchuk V.V. , Tremtyachny V.I.
Published: September 2022

Background: Implantation is becoming more widespread in such areas of modern medicine as orthopedics and traumatology. Due to the lack of an adequate substitute for natural bone, combined approaches are used. For older patients, the problem is exacerbated by a decrease in bone mineral density. When choosing a scheme for the surgical treatment of long bone fractures, preference is given to simple and maximally sparing approaches. In this regard, the main task of osteosynthesis is to provide optimal mechanical channels not only for the fracture healing process, but also to restore full functional capabilities in the future. The paper considers the urgent task of optimizing and increasing the efficiency of planning rehabilitation measures, including taking into account the individual characteristics of a particular patient, and the results are of fundamental and applied importance.

Objectives: development of physical and mathematical models for modeling the stress-strain state of the elements of the musculoskeletal system to optimize the planning of bone surgeries when installing implants.

Materials and methods. For the analysis, both specific clinical results and modern methods of computer modeling and processing of results were used. The advantage of physical and mathematical models based on the used finite element method is the possibility of optimizing the design of prostheses and reducing the problems caused by osteopenia.

Results: To illustrate the proposed approach, a specific example of the treatment of a comminuted fracture of the humerus in an elderly patient is considered. To describe the physicomechanical properties of bone tissue, sets of standard data on the main characteristics of tissues and materials of implants such as elastic modulus and Poisson's ratio were used. As the bone grows together, simultaneously with a decrease in stresses, the difference between the stress on the entire structure and the stress on the bone decreases. This indicates that the bone begins to take on an increasingly significant relative part of the load, which should have a positive effect on its bone mineral density.

Conclusions: The advantages of modeling using the finite element method and by non-invasive modeling of the work of the patient's musculoskeletal system with various variants of prostheses (implants) and the choice of the most optimal one are shown. It was found that the use of the Von Mises stress-strain state as a criterion for assessing the stress-strain state of the system gives effective assessments of the reliability of the structure and its elements.

Published: September 2022

Background. The use of antimicrobial peptides is one of the possible ways to overcome the threatening rapid growth of resistance of microorganisms to traditional antibiotics. Of the particular role in this context is gramicidin S (GS), which is used for topical medical applications for over 70 years. An acute hemolytic side effect of GS on human cells prevents its systemic use. Understanding the molecular mechanisms of interaction of GS with biological membranes will enhance its bactericidal effect on the one hand, and reduce the negative side effects on human cells and thus expand the range of antibacterial peptides to combat infectious diseases caused by resistant microorganisms.

Objectives. Study of the effect of different doses of the antimicrobial oligopeptide antibiotic GS on the morphological and electrophysical characteristics of human erythrocytes during in vitro incubation.

Materials and methods. Morphological changes of erythrocytes of healthy donors after preliminary incubation with GS at concentrations 5–40 μg/ml were studied by flow cytometry using resistance pulse spectroscopy. Single-cell volume, erythrocyte volume distribution in the population was measured, and the electrical breakdown potential of the human erythrocyte plasma membrane was determined.

Results. Incubation of human erythrocytes with sub-lytic concentrations of GS is accompanied by a redistribution of erythrocytes in this population by volume with an increased number of smaller erythrocytes with less resistance of the membrane to electrical breakdown. However, increasing the concentration of GS to 40 μg/ml leads to an increase in the proportion of cells of increased volume with increased resistance to electrical breakdown of the membrane. Possible mechanisms of morphological changes of erythrocytes under the action of GS are discussed.

Conclusions. Incubation of erythrocytes with GS at concentrations 5–40 μg/ml is accompanied by a redistribution of cells by volume and changes in the resistance of their plasma membrane to electrical breakdown due to destabilizing membrane-tropic action of the peptide, microsimulation, or cytoskeleton rearrangement.

Authors: Mahdi Noura , Bakr Nabeel
Published: September 2022

In this work, sodium-doped copper zinc tin sulfide (CZTS) thin films are prepared by depositing them on glass substrates at temperature of (400±10) °C and thickness of (350±10) nm using Chemical Spray Pyrolysis (CSP) technique. 0.02 M of copper chloride dihydrate (CuCl2.2H2O), 0.01 M of zinc chloride (ZnCl2), 0.01 M of tin chloride dihydrate (SnCl2.2H2O), and 0.16 M of thiourea (SC(NH2)2) were used as sources of copper, zinc, tin, and sulphur ions respectively. Sodium chloride (NaCl) at different volumetric ratios of (1, 3, 5, 7 and 9) % was used as a dopant source. The solution is sprayed on glass substrates. XRD diffraction, Raman spectroscopy, FESEM, UV-Vis-NIR, and Hall effect techniques were used to investigate the structural, optical, and electrical properties of the produced films. The XRD diffraction results revealed that all films are polycrystalline, with a tetragonal structure and a preferential orientation along the (112) plane. The crystallite size of all films was estimated using Scherrer's method, and it was found that the crystallite size decreases as the doping ratio increases. The FESEM results revealed the existence of cauliflower-shaped nanoparticles. The optical energy band gap was demonstrated to have a value ranging from 1.6 to 1.51 eV with a high absorption coefficient (α ≥104 cm-1) in the visible region of the spectrum. Hall measurements showed that the conductivity of CZTS thin films with various Na doping ratios have p-type electrical conductivity, and it increases as the Na doping ratio increases.
Multiple Docking of Fluorescent Dyes to Fibrillar Insulin

Published: September 2022

The co-localization of the donor and acceptor fluorophores capable of transferring the energy by the Fӧrster mechanism, on the molecular scaffold of amyloid fibrils offers new opportunities not only for refinement of the amyloid detection and structural analysis, but also for designing photonic nanodevices on their basis. The assembly of these systems involves the non-covalent dye-protein interactions which can hardly be characterized in terms of a precise dye location within the fibril structure that is required for fabricating the FRET-based light harvesting systems or photonic nanowires. In view of this, the dye-fibril binding process deserves a detailed in silico study. In the previous molecular docking studies of the FRET donors and acceptors interacting with the insulin model fibrils we considered only one ligand during the simulation procedure. However, the real situation is much more complicated, when the multiple ligands can compete for the same binding site, a direct complexation between the dyes on the fibril scaffold can take place, the spatial distribution of the bound fluorophores can be unfavorable for the energy transfer, etc. In addition, the mutual orientation of the donor and acceptor molecules essentially contribute to the efficiency of the Förster resonance energy transfer (FRET) in the investigated systems. The present study was undertaken to gain molecular docking insight into the binding of the donor (Thioflavin T) and acceptor (Congo Red or a phosphonium dye TDV) fluorophores to the insulin amyloid fibrils using the multiple docking approach. The employed PatcDock and SwissDock webserves provided evidence for the preferable association of all dyes with the fibril grooves. The protein-ligand interaction profiler (PLIP) was employed for analyzing the (InsF + ThT +CR) and (InsF + ThT + TDV) systems. The revealed binding modes and the types of the dye-fibril interactions may be of importance for a more detailed analysis of the FRET process in amyloid systems and may serve as a background for further in silico studies of the cascade FRET on the amyloid fibril scaffold.
DISTRIBUTED PRINTING: the use of a distributed 3D printing method as a new model of complex architectural project delivery
Authors:   , Zhang Tianming
Published: September 2022

Distributed printing method is a process that allows complex architectural components to be fabricated by more than one production source at a global and local scale. While 3D printing (also known as additive manufacturing) is considered a revolutionary technology for many manufacturing industries, the application in the architectural industry lags in leveraging the potential of this innovative technology. Today, most architectural designers have to utilise large and expensive 3D printing equipment to create monolithic, singular buildings. Accordingly, there is a need for finding another workflow to deliver complex architectural structures, and the distributed printing method holds promise for this application.

The imminent question therefore is; how small-scale architecture can leverage the power of distributed 3D printing to deliver complex architectural structures. However, the current knowledge in distributed 3D printing for architecture has received little attention in the research literature.

To test the hypothesis that distributed printing methods could lead to faster and more affordable project delivery, a mixed methodology strategy, including literature review, case study, experiment, and simulation, was utilised in this thesis. Literature and some cases were researched to identify the potential workflow of distributed printing. Moreover, a series of small-scale models were fabricated to test the factors which may affect distributed fabrication. Furthermore, an experiment was conducted to simulate the entire process of delivering an architectural project using distributed printing methods.

The architecture proposed utilising digital design tools and the method of distributed printing to create an envelope formwork as a way of creating an outer shell or skin for the structure. It is not intended that the components form the final envelope skin.

In summary, the distributed printing methods positively impact complex architectural project delivery when utilised strategically. With the support of the distributed printing platform, architecture has the potential to utilise a larger number of printers beyond any single factory, therefore leveraging the full power of distributed printing methods to create time and cost benefits. At the same time, some negative factors, such as logistics delay, also show the risk of using distributed equipment worldwide. In the future, the ideal method will be more likely to provide distributed sites with closer geographical distance to users.
Corruption distance and FDI location choice.
Authors:   , Rodina Zhanna
Published: September 2022

Corruption is a complex, multifaceted phenomenon, often functioning as a ‘critical institution’ filling institutional voids. The topic of corruption has attracted widespread attention in economics, management, and international business since the end of the 20th century. Some argue that it negatively affects countries’ economic growth, FDI inflows and distorts the allocation of public spending on healthcare and education. Others believe that corruption can serve as ‘grease’ to the wheel of commerce.

In my thesis, I explored the interlinkages between pervasive corruption (i.e., stable, known) and the location choice MNEs make through applying corruption distance with direction and magnitude to the relationship.

Additionally, I included VUCA conditions dominating our world today – volatility, uncertainty, complexity, and ambiguity. By matching them to the institutional factors – political stability, government effectiveness, policy uncertainty and arbitrary corruption (i.e., unpredictable, unknown); I enhanced the understanding of the effect of institutions on a firm’s location decision in a worldwide contextThis research applied a quantitative approach and analysed 940,485 observations – investments made by 1,113 firms in 169 countries over five years. I chose the Healthcare sector because of its importance in today’s world of epidemics, pandemics and the ageing population. Through the logistic regression analysis, this thesis found that corruption indeed acts as ‘grease’ and attracts firms instead of repulsing them. Moreover, the larger the corruption distance is, the more likely the firms will invest. Additionally, it was found that policy uncertainty has a significantly negative moderating effect on the relationship between corruption distance and FDI location choice.

My research findings contribute to both institutional theory and location choice literature by answering the puzzling question of the true nature of the relationship between corruption and FDI location choice. My research also contributes to the literature incorporating VUCA dimensions. It emphasises the importance of including them in any modern study focusing on current global issues and the ever-changing environment increasingly affected by VUCA factors.

Precise determination of the isotope masses of superheavy elements obtained by the complete fusion of 48Ca+ ions with Au, Pb, Bi, U, and Pu targets can provide valuable information on the mechanisms of nuclear reactions leading to the formation of these elements. A specialized multi-turn time-of-flight mass spectrometer is to be used to match the goal. The source of the target isotopes is a DC-280 cyclotron, a «factory of superheavy elements» at the Joint Institute for Nuclear Research (JINR, Dubna, Russia). The point of the problem is that ions of superheavy elements are formed quite rarely even in the specialized accelerator of JINR: during the last experiment, the frequency of their appearance was up to 10 events per day. Precise determination of the mass number requires comparing the time of flight of a superheavy ion through a mass analyzer with the same time for a calibrant ion, the mass number and charge of which are precisely known a priori from the process of its formation. Implementation of such a mass spectrometric analysis required the development of an ion source capable of stable operation for a long time. To solve the problem, a number of ion sources were considered. The choice of an ion source with electron ionization is substantiated. A source with a crucible in which the calibrant evaporates during heating was proposed and tested. Various substances (PbBr2, Nd, C60, fullerene soot) were considered as a calibrant. The mass spectra of these compounds are presented, namely, the spectrum of neodymium compounds and the mass spectrum of fullerene soot. It is shown that the use of fullerene soot is optimal, since the mass spectrum of fullerene soot contains ions in the range of mass numbers from 12 to 800 and higher. Moreover, the mass spectrum of fullerene soot contains many peaks in the mass number region of interest 275 – 300 a.m.u. It has been experimentally shown that the ion intensities within the indicated range differ by less than an order of magnitude which makes the use of fullerene soot a standard sample for calibration of a high-resolution time-of-flight mass spectrometer.

The book is a linguistic and textological study of the first full Russian translation of the Quran, printed in St. Petersburg in 1716 by order of Peter the Great against the background of the previous European tradition. The first printed translation of the Quran in Peter the Great's time was intended for an enlightened readership familiar with various kind of itineraries, which describe the customs, beliefs and mores distant peoples, and was intended to give the most complete picture of Islam and the Quran as the holy book of Muslims. The paper substantiates the hypothesis that the translation belonged to Pyotr Andreevich Tolstoy, Russian envoy to the Ottoman Empire in 1711-1714. The study is accompanied by the Russian translation from the Russian State Library copy (RGB, IC C-2°/16-K), as well as French original from a digitized 1685 edition of The Hague, chronologically and textologically closest to the Russian translation. For specialists in the history of Russian literary language, orientalists and all those interested in the history of Russian culture in the 18th century.

En este artículo se analizan las potencialidades y limitaciones de la Educación Básica a distancia implementada por el Gobierno Federal y la Secretaría de Educación Pública para dar continuidad a la educación en el marco de la emergencia sanitaria provocada por el SARS COV-2. Desde una de investigación de tipo cualitativo, de corte documental, se da respuestas a las siguientes preguntas: a partir del desarrollo de la pandemia y su evolución en México, ¿cuáles han sido las medidas que se tomaron para dar continuidad a la Educación Básica?, ¿cuáles han sido los medios utilizados para dar continuidad a Educación Básica?, ¿cuáles son las ventajas y desventajas que brinda la educación básica a distancia para dar cumplimiento a los objetivos planteados por la Secretaría de Educación Pública? Se encontró que, la urgencia por cubrir el vacío que dejaron las escuelas, a través de las pantallas, no ha tomado en cuenta los múltiples factores que entraña un cambio de la educación presencial a la educación a distancia. México ha acumulado una serie de intentos, en diversos programas que pretendían integrar la tecnología en la educación; desde 1997 y hasta 2016, se llevaron a cabo seis programas de educación digital impulsados por el Gobierno Federal, los cuales no pudieron cumplir cabalmente su objetivo.

Published: September 2022

A cross sectional data collected through a structured questionnaire coupled with an interview schedule from 360 rice farmers selected via multi-stage sampling technique was used to determine the labour efficiency of rice farmers in Nigeria’s North-Central region. Both descriptive and inferential statistics were used to analyze the 2020 cropping season data. The empirical evidences showed a farming population that is gender bias due to stereotypes, that affected women access to and control over productive resources. Besides, economic-productive people that explored pecuniary advantages in order to achieve economies of scale engaged in cultivation of thinly uneconomic holdings. The poor economic status of the farm families made most of the farmers to rely on family labour for farm operations, thus keeping most of their children and young ones out of school. Furthermore, most of the farmers were fairly efficient in the use of labour with little technical support required to enable them achieve optimum labour efficiency level (frontier point). However, the empirical evidences showed competition for labour demand between farm and off-farm activities and conservative and complacency attitudes due to longevity in the enterprise to be the factors that affected labour efficiency. Therefore, the study calls for gender mainstreaming in agricultural budget to overcome women’s challenge on productive resources; incentivized the enterprise viz., credit provision; adoption of bottom-to-top approach in research and practical demonstration approach in transfer of innovative rice technologies.

A View on Guidelines for Teaching and Learning of Quadratic Curves in Mathematics Curriculum and the Construction of Textbooks and Teacher’s Guide Books
Authors:   The Korea Society Of Educational Studies In Mathematics, Yang Seong Hyun
Published: September 2022

With the introduction of the 2015 revised mathematics curriculum, changes were accompanied not only in the content system for quadratic curves, but also in ‘teaching and learning methods and precautions’ including the method of introducing quadratic curves. However, as a result of analyzing the consistency aspect of the 2015 revised mathematics curriculum and the high school  textbooks and teacher's guide books written based on it, two points of improvement were derived in ‘teaching and learning methods and precautions’. First, the composition of the textbooks and teacher’s guide books written based on the revised curriculum did not partly correspond to it. Second, it was found that some of ‘teaching and learning methods and precautions’ conflicted with the unit school curriculum arrangement due to the completion standard according to the pre-requisite course arrangement in the mathematics course and needed improvement. If textbooks and teacher’s guide books do not match the curriculum and are composed heterogeneously, considerable confusion may be encountered at school sites, especially for teachers who guide students. In mathematics, where the content area is the central element of the curriculum, more careful attention is required for the coherence of the curriculum and textbooks.

This text analyzes how turning of foods into heritage is a social process that produces indigeneity via food activism. It presents the case of the Enlace Group for the Promotion of Amaranth in Mexico (Grupo Enlace para la Promoción del Amaranto en México) a player in the argument over food sovereignty, which propels the production, transformation and consumption of this grain. It illustrates its food events, organizational practices and the narratives that provided amaranth with a series of values related to its place in the Mesoamerican diet, which, updated as indigenous and ancestral food, helped it become known as an intangible heritage of Mexico City (cdmx). We display the relevance of this type of activism for the production of indigeneity in the scope of food heritage.

This article analyzes the relations between gender, emotions and places, through the idea of women’s geographies of fear. On the one hand, I look into the specific spatial effects of fear of violence in women’s everyday lives and, on the other, I propose some analytical keys that can configure a theoretical-empirical framework of these geographies of fear from a gender perspective, emphasizing the geographical processes that are triggered in the urban experience. Our findings are backed by data from two studies on sexual harassment and other forms of sexual violence in public spaces in the cities of Puebla and Guadalajara, in Mexico.

While the former are afraid - with good reason - of violence, robbery, kidnapping and disappearance; women, in addition to accumulating these same fears, fear above all sexual violence, which ranges, as you will see in the contributions to this dossier, from leering, touching, rape and femicide.
Impact of Covid-19 on Tourism: Evidence from SAM Assessments of Hungary and Turkey
Authors: AKKEMİK Ali , PERLAKY Denes
Published: September 2022

Due to the Covid-19 pandemic, international mobility was largely restricted, which led to severe declines in tourism activities. This paper estimates the economic impacts of this decline in Turkey and Hungary, using social accounting matrix modeling. The authors constructed social accounting matrices separately and estimated the macroeconomic impact of the decline. The results reveal that the decline in international tourism revenues reduced GDP by 2.6% in Turkey and 5.9% in Hungary, with 0.9% and 2.0% loss of employment in Turkey and Hungary, respectively. These figures are much larger compared to the economic gains from the fiscal rescue packages.

Objective Considerable evidence suggests that neuroinflammation plays an important role in the pathophysiology of major depressive disorder (MDD). However, the relationship between serum C4 binding protein (C4BP) and white matter (WM) tract integrity in MDD has not been investigated.Methods We obtained diffusion tensor images of 44 patients with MDD and 44 healthy controls and performed TRActs Constrained by UnderLying Anatomy (TRACULA) analysis to assess WM tract integrity. Serum C4-binding protein alpha chain (C4BPA) and C4- binding protein beta chain (C4BPB) levels were measured and in-between group comparisons were obtained. The correlation between serum C4BP levels and WM tract integrity was examined.Results In comparison to healthy controls, both serum C4BPA and C4BPB were higher in MDD. Also, fractional anisotropy (FA) was increased in the left cingulum-angular bundle (CAB) in MDD, but not healthy controls (HCs). A significant correlation was found between serum C4BP and FA levels in the right cingulum-cingulate gyrus bundle (CCG) in MDD.Conclusion This study is the first to investigate the correlation between serum C4BP levels and WM tract integrity in MDD. We identified an increase in WM integrity in the left CAB region in MDD. Furthermore, serum C4BP levels were higher in MDD, and this finding correlated with increased WM integrity in the right CCG region.

Endüstri 4.0 devrimi ve Nesnelerin İnterneti (IoT) gibi teknolojilerle dijitalleşme, kaynaklarımızın ve ekonomilerimizin döngüsel olmasını gerektirmektedir. Başta Avrupa Birliği olmak üzere tüm ülkeler, kritik hammaddelerin sorumlu tüketiminin, üretiminin ve geri dönüşümünün sürdürülebilir kalkınma hedeflerine ulaşmanın bir yolu olarak çok önemli olduğu konusunda hemfikirdir. Ömrünü tamamlamış ürünlerden kritik hammaddelerin geri kazanılması için uygun maliyetli bir geri dönüşüm yöntemi, madencilikten çok daha az çevresel etkiye sahiptir. Biyo & hidrometalurjik yöntemler, kritik hammaddelerin, özellikle nadir toprak elementlerinin (NTE) çıkarılması için hızlı gelişen, seçici, çevre dostu ve uygun maliyetli teknolojilerdir. Bu makale, ikincil kaynaklara genel bir bakış sağlamakta ve kritik hammaddelerin kazanımı için ekonomik bir yol olarak hizmet edebilecek bazı umut verici yöntemlerin kullanımına ilişkin yürütülen çalışmaların senaryosunu özetlemektedir.
Zur Visualisierung von Bewegungsfunktionn in der v-a-Ebene
Authors: Alpers Burkhard
Published: September 2022

In diesem Beitrag werden die Vor- und Nachteile der Visualisierung von
Bewegungsfunktionen in der Geschwindigkeits-Beschleunigungs-Ebene
bei gegebenen kinematischen Restriktionen diskutiert. Die Darstellung
wurde von Broquère eingeführt, um zeitoptimale Sieben-Segmente-Profile
mit Ruckbegrenzung zu untersuchen. Seine Darstellung wird im Beitrag
aufgegriffen und auf ruckstetige Funktionen erweitert, die sich ähnlich
visualisieren lassen.

On Visualizing Motion Functions in the Velocity-Acceleration
Plane / Abstract
In this contribution we discuss the advantages and disadvantages of visualizing
motion functions in the velocity-acceleration-plane which was introduced
by Broquère for depicting time-optimal seven-segment profiles
with restricted jerk. His representation will be used in this contribution
and it will be extended for jerk-continuous functions.

Published: September 2022

Das Ansteuern von Compliant-Mechanismen zu Zielpositionen ist besonders
herausfordernd, da analytische Modelle die inverse Kinematik
nicht oder nur teilweise aufstellen können. Anhand eines beispielhaften
Compliant-Mechanismus zeigt diese Arbeit wie Methoden des Machine
Learning angewandt werden können, um die entsprechende Kinematik
erfolgreich zu lernen. Damit sind Aussagen über die Ansteuerungen der
Aktuatoren möglich, mit deren beliebige Punkte mit dem Mechanismus
erreicht werden.

Controlling of compliant-mechanisms with reinforcement learning
Driving compliant-mechanisms to target positions is particularly challenging
since it is not or hardly possible to set up the inverse kinematics with
analytical models. On the basis of an exemplary compliant-mechanism,
this work shows how machine learning methods can be applied to successfully
learn the corresponding kinematics. This allows statements
on how the actuators have to be controlled in order to reach arbitrary
points with the mechanism.

Usia dini merupakan periode yang sangat krusial bagi seorang anak. Khususnya pada perkembangan anak karena sangat berpengaruh terhadap perkembangan pada periode berikutnya hingga masa dewasanya. Perilaku bullying pada anak usia dini sering sekali diabaikan oleh orang tua bahkan guru, dengan anggapan bahwa anak usia dini belum memahami benar mana yang baik dan mana yang buruk, sehingga wajar dilakukan anak usia dini. Padahal perilaku bullying ini memiliki dampak yang sangat besar terutama bagi korban, seperti depresi, rendahnya kepercayaan diri atau minder, pemalu dan penyendiri, merosotnya prestasi akademik, merasa terisolasi dalam pergaulan, terpikir atau bahkan mencoba untuk bunuh diri apabila terjadi secara terus menerus, selain itu bullying juga memiliki dampak negatif pada perkembangan karakter anak, baik bagi si korban maupun pelaku. Pengabdian masyarakat ini berupa penyuluhan kepada orangtua yang memiliki anak usia dini mengenai perilaku bullying dan dampaknya pada anak usia dini. Penyuluhan ini merupakan upaya untuk memberikan pemahaman kepada orangtua tentang perilaku bullying di usia dini. Hasil yang didapat dari pelaksanaan pengabdian masyarakat ini adalah berupa penambahan wawasan pengetahuan dari peserta kegiatan mengenai perilaku bullying, dampak bullying dan faktor faktor yang dapat menyebabkan munculnya perilaku bullying pada anak. Early age is a very crucial period for a child. Especially in child development because it is very influential on development in the next period until adulthood. Bullying behavior in early childhood is often ignored by parents and even teachers, with the assumption that early childhood does not really understand what is good and what is bad, so it is natural for early childhood to do. The perceived impact of the danger of bullying in terms of victims is depression, low self-confidence or inferiority, shy and aloof, declining academic achievement, feeling isolated in relationships, thinking, or even trying to commit suicide if it occurs continuously, besides that bullying also has an impact. negative on the character development of children, both for the victim and the perpetrator. This community service is in the form of counseling parents who have early childhood about bullying behavior and its impact on early childhood. This counseling is an effort to provide understanding to parents about bullying behavior at an early age. The results obtained from the implementation of this community service are in the form of adding insight into the knowledge of the participants regarding bullying behavior, the impact of bullying and the factors that can lead to the emergence of bullying behavior in children.
