ELEKTRONSKO NASILJE NA DRUŠTVENIM MREŽAMA IZ PERSPEKTIVE UČENIKA SREDNJIH ŠKOLA
Authors: Milošević Danijela , Milošević Dijana
Published: March 2024

Digitalni mediji, kao jedni od ključnih agenasa socijalizacije, pružili su mnogobrojne mogućnosti, ali i doprineli povećanoj bezbednosnoj opasnosti adolescenata u virtuelnom okruženju. Usled sve veće upotrebe društvenih mreža dolazi do češće pojave elektronskog nasilja među adolescentima, što se na različite načine manifestuje na njihov život ostavljajući socijalne, fizičke, psihološke i druge posledice. U fokusu ovog rada je ispitivanje zastupljenosti i učestalosti elektronskog nasilja među učenicima srednjih škola, kao i njihove preporuke o načinima preventivnog delovanja u rešavanju problema elektronskog nasilja. Istraživanjem je obuhvaćeno 245 srednjoškolaca iz predela Jugoistočne Srbije. Rezultati pokazuju visoku učestalost provođenja vremena na društvenim mrežama, povezanost broja provedenih sati na društvenim mrežama sa doživljavanjem ili činjenjem oblika elektronskog nasilja među vršnjacima i veću zastupljenost uloge žrtve od nasilnika. Kvalitativni nalazi obuhvataju različite predloge srednjoškolaca za rešavanje problema elektronskog nasilja, koji su svrstani u okviru osam kategorija (porodično vaspitanje, edukacija u školi, pomoć stručnih lica i drugih aktera, veće angažovanje države i kompanija u zaštiti bezbednosti dece i mladih na internetu, briga o mentalnom zdravlju i dr). Pored navedenog, autori svoj doprinos daju iznošenjem potencijalnih rešenja u redukciji elektronskog nasilja na društvenim mrežama, koja uključuju međusobnu saradnju svih agenasa vaspitno-obrazovne delatnosti.

U radu je rasvetljavan fenomen digitalne pismenosti koji je posmatran kroz prizmu konektivističke teorije učenja. U tom kontekstu prikazani su rezultati istraživanja koje je imalo za cilj utvrđivanje stavova i preferencije adolescenata po pitanju čitanja štampanih i digitalnih formata teksta i medija uopšte, kao i utvrđivanje stavova o konkretnim čitalačkim praksama, kako u tradicionalnom tako i u digitalnom čitalačkom okruženju. Utvrđivane su povezanosti između opšteg odnosa prema čitanju i sklonosti prema klasičnom i digitalnom čitanju u svrhu učenja. Podaci su dobijeni obradom N=599 upitnika reprezentativnog fokusiranog uzorka adolescenata uzrasta od 15 do 19 godina, učenika gimnazija i srednjih škola u Republici Srbiji. Anketni upitnik je sadržao 32 pitanja. U obradi podataka primenjena je deskriptivna, korelaciona i regresiona analiza. Istraživanjem se došlo do zaključka da je kod adolescenata opšti odnos prema čitanju značajno povezan sa dimenzijama odnosa prema klasičnom čitanju štampanog teksta i multimediji.
READING THE FABRIC
Authors: VÉRY Dalma
Published: March 2024

Although it seems to be apparent today that language is not a “transparent medium”, interpretations focussing on the narratives of texts still seem to outweigh the efforts oriented upon how the text actually addresses the reader. The plain investigations of narratives do not concern themselves with what the text says in the way it speaks, but concentrate on assumed threads of sense and on hidden symbolism. The hermeneutic task is to engage in a dialogue with the text by way of concentrating on the surface of its fabric as texture, i.e. to ask what way the text addresses the reader inasmuch as it speaks and how one hears it. In the attempt to unfurl the text as fabric, one has to lay bare the phenomenal sense of the sign, of speech as language, of hearing, but also of the text as space. In this way, one may actually follow the intertwining threads of perception, sense and affectedness throughout the process of reading, and may thus gain genuine insight into what the text as fabric reveals. Excerpts from James Joyce’s Ulysses demonstrate how the eminent unfolding of the fabric requires attention to its diverse facets.

Authors: Mohammad Thoha  , Hilmi Qosim Mubah
Published: March 2024

The world of education in this era is trapped in a pragmatic mindset in almost all sectors. Educators and education staff, students, financing, learning processes, fulfillment of infrastructure, assessment, and management services seem to work following a mechanical pattern and deny humanistic elements of humans which are full of politeness, patience, cooperation, mutual understanding, and so on. This research uses the Systematic Literature Review (SLR) method with a choice of Preferred Reporting Items for Systematic Reviews and Meta-analyses or PRISMA. The results of this study show that emotional intelligence as a basis for implementing early childhood education management can positively affect educators and education staff. The values of emotional intelligence which include the ability to motivate oneself, resistance to frustration, self-control, and the ability to balance emotions and ratios will lead the entire educational community to enjoy a harmonious, humane, and warm educational process.

Published: March 2024

The digital literacy of parents will serve as the primary example for preschool children in utilizing digital technology. The comprehension and selected mediation model chosen by parents will determine a child's development in using digital devices and media. This qualitative descriptive study aims to identify the role of parents in responding to the various productivity and phenomena that occur in their children during interactions with digital technology in their developmental stages. The study involves 29 parents of preschool children, 1 school principal, and 2 teachers at TK Plus Al Adalah. Data is collected through literature exploration, interviews, observations, and documentary studies. The collected data is analyzed through data reduction, presentation, and conclusion. The results of the study reveal that: 1) Parents can facilitate their children in accessing digital technology, but parental literacy and mediation are not yet fully effective and optimal. 2) Further efforts are needed to enhance parents' understanding of digital literacy and develop inclusive learning strategies for children through digital technology approaches. 3) It is inappropriate to perceive the development of digital technology and content on social media solely as consumable material, as it also represents a form of interaction that indirectly guides individuals in developing specific digitalization and understanding skills. 4) Therefore, parents and teachers require guidance from practitioners, especially regarding aspects of developing and integrating digital technology-based learning experiences for preschool children.

La adolescencia es un período en la vida caracterizado por diversas demandas al individuo, lo que puede ser fuente de estrés. Frente a ello, los adolescentes recurren a determinadas estrategias de afrontamiento pero, al mismo tiempo, muchos de ellos también se involucran en consumo de alcohol. El objetivo del presente estudio es identificar las relaciones entre estrategias de afrontamiento y consumo de alcohol en adolescentes estudiantes del nivel medio superior. Se realizó un estudio exploratorio transversal cuantitativo, mediante muestreo aleatorio estratificado. Participaron 1555 estudiantes de 15 a 21 años (43.3% hombres) de tres escuelas preparatorias de la universidad de Guadalajara. Se emplearon la Escala de Afrontamiento para Adolescentes (ACS), el cuestionario CAGE y la prueba AUDIT. Los resultados indican un mayor uso de la mayoría de las estrategias de afrontamiento (productivas y no productivas) en los estudiantes consumidores de alcohol y correlaciones positivas entre el nivel de consumo y las estrategias de afrontamiento. Estos resultados se analizan en función de un posible mayor nivel de estrés entre los estudiantes consumidores.

Continuing nutritional problems and stunting can become an inhibiting factor in national development. Community knowledge, attitudes, and skills in processing food sources, especially local food sources, are still very lacking. The opinion that nutritious food is expensive so that they prioritize economic reasons and ignore health problems, is still common in society. A local wisdom-based approach is an important strategy so that people can be aware of the capabilities of food sources and the environment around them and are able to process them into nutritious food sources. The aim of community service is to create nutritional cadres to prevent anemia who have the ability to understand the potential of local food sources and can process them simply as a source of nutritious food, easy to obtain and cheap, especially for river settlement communities in South Kalimantan. Community service activities are carried out in Aluh-Aluh District which is one of the locus of stunting villages in 2022. Thorough identification using an in-depth interview approach is used to find out various matters related to health knowledge, especially anemia symptoms. By utilizing counseling from sources who understand local wisdom and food sources to prevent anemia, it is hoped that more knowledge will be created about local food resources that are useful for preventing anemia. Approaches to adolescents with counseling are expected to be able to encourage additional knowledge and positive attitudes and be able to utilize local food sources independently.

Published: March 2024

Purpose – This research aims to observe the attitudes and behavioural intentions of young tourists in relation to their experiences of consuming PBF, including value consumption, concern for the environment and perceived cost as influencing factors. Methodology/Design/Approach – Considering that it is almost impossible to determine the sample frame for young tourists in Indonesia, this research used a non-probability sample to collect the sample. The study focused on young tourists aged 18 to 35 years old who have experience of consuming PBF while travelling. A self-administered online questionnaire was provided to tourists visiting a destination from July to September 2022, resulting in 267 usable responses. Findings – Tourists’ attitude towards PBF leads to their intention to buy again during or after their visit and to offer profitable e-WOM. In addition, perceived cost moderates the relationship between attitude and e-WOM; however, it does not provide evidence for the moderating role between attitude and repurchase intention. Originality of the research – This study highlights the value of consumption, concern for the environment and perceived costs as factors influencing tourists’ attitudes and behavioural intentions towards public transport.
Reexamining the Schwarzschild Metric: Implications for Black Hole Interiors and Cosmology
Authors: Laforet Christopher
Published: March 2024

This study challenges the conventional interpretation of the interior Schwarzschild metric, particularly the notion of a timelike radius leading to "spaghettification" at the curvature singularity. Contrary to previous assumptions, the angular term of the interior metric signifies not shrinking spheres but rather the precession of reference frames within spherically symmetric voids – analogous to cosmic voids – expanding over time. This is the result of treating the internal radius as an imaginary radius instead of simply a time-dependant scale factor of the angular term of the metric. Moreover, it is proposed that the expansion of these voids is the source of Dark Energy without the need for a cosmological constant. Comparisons with observational data reveal the model's compatibility with the $\Lambda$CDM framework, underscoring its viability as a model of cosmology. Additionally, we present a novel coordinate chart facilitating visualization of transitions between the exterior spacetime surrounding massive objects and the interior voids, without traversing an event horizon. Intriguingly, the Schwarzschild metric unveils a duality between our Universe and an Antiverse, with the event horizon demarcating their convergence. This duality sheds light on fundamental properties such as electric charge and quantum spin, elucidating their connection to spacetime geometry and the existence of mirror antimatter within the Antiverse.
Assembly Theory of Binary Messages (How to Assemble a Black Hole and Use it to Assemble New Binary Information?)
Authors: Łukaszyk Szymon , Bieniawski Wawrzyniec
Published: March 2024

Using assembly theory, we investigate the assembly pathways of fixed-length binary strings formed by joining the individual bits present in the assembly pool and the strings that entered the pool as a result of previous joining operations. We show that the string assembly index is bounded from below and above, and we conjecture about the form of the upper bound. We show that a string having the smallest assembly index can be assembled by an elegant trivial program of length equal to this index, if the length of the string is expressible as a product of Fibonacci numbers. We conjecture that there is no binary program that has a length shorter than the length of the string having the largest assembly index that could assemble this string. We conjecture that a black hole surface is defined by a balanced distinct string that satisfies the upper bound of a distinct string assembly index. The results confirm that four Planck areas provide a minimum information capacity that provides a minimum thermodynamic (Bekenstein-Hawking) entropy. Knowing that the problem of determining the assembly index is at least NP-complete, we conjecture that the problem of determining the assembly index of a given binary string is NP-complete, while the problem of creating the string so that it would have a predetermined maximum assembly index is NP-hard. Therefore, once the new information is assembled by a dissipative structure or by a human, increasing the information entropy according to the second law of infodynamics, it is subject to the second law of thermodynamics, and nature seeks to optimize its assembly pathway.
Redefining the Narrative: How Work from Home Job Demands Elevate Workplace Anxiety but Enhance Psychological Capital
Authors: Magwegwe Frank , Sithole Snenhlanhla
Published: March 2024

Globally, workplace stress and anxiety are at an all-time high, with 42% of employees experiencing daily work-related stress and anxiety. Drawing from workplace anxiety (WA) theory (Cheng & McCarthy, 2018), we advance a model that considers four job demands – role ambiguity, work overload, job insecurity, and work-home conflict – as sources of daily WA, and in turn the downstream effects of WA on psychological capital (PsyCap). Our model posits gender as a moderator of the association between job demands and WA, and digital technology characteristics as moderators of the association between WA and PsyCap. We tested our predictions on a sample of 162 South African employees. Consistent with our predictions, we found positive effects of job demands on WA, with the relationship being stronger for females. Contrary to expectations, we found positive effects of WA on PsyCap, suggesting an adaptive function of WA. Perceived ease of use of digital technology moderated the association between WA and PsyCap, such that the association was strong at higher levels of perceived ease of use. This research advances our understanding of the sources of WA, the adaptive function of WA, and predictors of PsyCap. Broadly, our study adds to understanding emotions’ impact on workplace behavior.

Objectives: To study sociodemographic and clinical variables including psychiatric comorbidities in patients with irritable bowel syndrome.

Methods: A total of 150 patients were screened to select 100 patients for the study who were attending a medical gastroenterology clinic in a tertiary care centre in north India. Diagnosis of IBS was made using Rome IV criteria and severity of symptoms were assessed by the Irritable Bowel Syndrome Symptom Severity Scale (IBS-SSS). Clinical evaluation was done for screening of psychiatric comorbidities and diagnosis was made as per DSM 5. Depression, Anxiety and Stress Scale - 21 Items (DASS-21) and Somatic Symptom Scale–8 (SSS-8) were used to assess depression, anxiety, stress and somatic symptoms.

Result: The mean age of cases was 35.6 years and majority were i.e., 38.0% in 18-29 years. Males were 62.0% and females were 38.0%. 61.0% of the cases were diagnosed with Moderate IBS. Evaluation on DASS-21 revealed 53.0% were in moderate category in depression, 43.0% were having moderate anxiety and 36.0% were having moderate stress. 48% cases were in high category in somatic symptom scale. Psychiatric comorbidities were present in 29.0% of cases. Depressive disorders were most common psychiatric comorbidity.

Conclusion: Patients with IBS presenting to tertiary care centre in Northern India were mostly young males living in semi-urban area, belonging to hindu region, married and had a nuclear family. Patients with IBS commonly have associated psychiatric disorders; anxiety disorders and depression are most common.

Urban sprawl is recognized as one of the most critical drivers disrupting the functional integrity of rural and natural landscapes. A systematic multiscale study has yet to be conducted to measure the Megalopolis of Mexico City's regional extent, comprising ca. 23 million inhabitants. This paper investigates land cover, land use, vegetation and soil changes at macro-regional, regional, local and site scales. Land cover/use data from the 1970s and 2018 were used as the primary input to analyze changes using remote sensing and geographical information systems. At the local scale, fieldwork data from the 1970s, 1990s, and 2020 served as the primary input and were subjected to multivariate analyses. At site scale, soils profiles and hydrological balance analyses at micro-basin level were conducted. Furthermore, social perception of changes was investigated among local residents/stakeholders using semi-structured interviews with four communities. Outcomes were validated to reach 85 percent accuracy in cartographic and 95 % statistical outputs. At the regional scale, land-use changes, especially human settlements, increased from about four to almost 40 % between 1970 and 2018 , with significant incursion into rural landscapes. At the local scale, analyses revealed significant decline in predominantly cold-humid vegetation types and conversion of agricultural fields into peri-urban landscapes. Site scale revealed the predominant importance of soils as the core landscape component for water infiltration and carbon sequestration. Nested multi-scale analyses revealed different disrupting processes which are hidden at one scale and evident at another. Poorly implemented, disconnected urban and environmental policies prevail as the main driving force, with implications for the weak local governance of rural communities. Regional integrated analyses are discussed in light of the relevance of urban resilience theory.
Technology In Ancient Peru. I Advanced Aerodynamic Knowledge in an Archaic Firing Structure on Top of the Main Pyramid of Caral
Authors: Sagripanti Jose-Luis , Wise Daniel , Yoon Elias , Kleihege Christopher
Published: March 2024

Abstract: We present a technological analysis of the architectonic complex associated with a firing structure (locally named fogón) on top of the Pirámide Mayor, the largest pyramid in Caral. This Archaic Period society flourished between ca 2,700 and 2,000 cal B.C. and was located near the Pacific Ocean on the north-central coast of present-day Peru. All approaches employed in this study demonstrated that the corridor with antechamber and duct on top of Pirámide Mayor of Caral was a sophisticated ventilation system capable of providing between 3,000 and 18,000 liters of air per minute for combustion in the attached fogón. The analysis indicates that ventilating the fogón must have been a major consideration in deciding a) the construction of the pyramid, b) locating the structure at the edge of a natural alluvial terrace, and c) orientating the pyramid towards the then contemporary prevailing winds. Results from the analysis of this fogón support practical decisions made by the builders and challenge the assumption that religion or politics were the only considerations in American pyramid building. It also indicates that a complex device, capable to delivering the considerable airflows reported in this study was within the reach of an archaic society in ancient Peru. The application of this structure to the production of a remarkably high thermal output and its implications on the knowledge of ancient Americans will be discussed in a following companion article.
Automatic Explanation Of Metal’s Phenomena By Application Of Artificial Neural Networks – Use Case For Hot Extruded Aluminum Alloy 6082
Authors: Goričan Tomaž , Terčelj Milan , Peruš Iztok
Published: March 2024

Artificial intelligence methods, especially artificial neural networks (ANNs), have recently been successfully used more and more frequently in the mathematical description of physical phenomena in the processing of metallic materials. Results based on measured data of phenomena in real production are often, at least locally, different or more complex than the results of established theories. In general, ANN models, which mostly work as "black boxes", allow us to improve production efficiency by themselves. The fact is, however, that a better understanding of the phenomena under consideration, which is otherwise enabled by classical mathematical approaches in the form of explicit mathematical formulas, could ensure even greater efficiency. In this article, therefore, a general concept is proposed to explain the discussed phenomena in metallic materials. The application of the concept is illustrated on the example of hot extrusion of aluminum alloy 6082, where CAE is used as an artificial neural network to model the phenomenon and predict the key parameters of the phenomenon. ChatGPT is used to explain the results according to the proposed concept. The basic idea is to enable practicing engineers to better understand the considered phenomena and results obtained by ANNs.

The cucumber mosaic virus (CMV) 2b protein is a suppressor of plant defenses and a pathogenicity determinant. Amongst the 2b protein’s host targets is the RNA silencing factor Argonaute 1 (AGO1), which it binds to and inhibits. In Arabidopsis thaliana, if 2b-induced inhibition of AGO1 is too efficient it induces reinforcement of antiviral silencing by AGO2, and triggers increased resistance against aphids, CMV’s insect vectors. These effects would be deleterious to CMV replication and transmission, respectively, but are moderated by the CMV 1a protein by sequestering sufficient 2b protein molecules into P-bodies to prevent excessive inhibition of AGO1. Mutant 2b protein variants were generated and red and green fluorescent protein fusions used to investigate subcellular colocalization with AGO1 and the 1a protein, and the effects of mutations on complex formation with the 1a protein and AGO1 were investigated using bimolecular fluorescence complementation and co-immunoprecipitation assays. Although we found that residues 56-60 influenced the 2b protein’s interactions with the 1a protein and AGO1, it appears unlikely that any single residue or sequence domain is solely responsible. In silico predictions of intrinsic disorder within the 2b protein secondary structure were supported by circular dichroism (CD) but not by nuclear magnetic resonance (NMR) spectroscopy. Intrinsic disorder provides a plausible model to explain the 2b protein’s ability to interact with AGO1, the 1a protein and other factors. However, the reasons for the conflicting conclusions provided by CD and NMR must first be resolved.

Gold nanohole arrays are periodic metastructures gathering huge interest for biosensing applica-tions. The grating-like structure defines their plasmonic mode features and their angular disper-sion can be used to highlight efficiently their interaction with the fluorescence emission of a properly tuned fluorophore. Resorting to a properly tuned/engineered/optimised plasmonic na-nohole array and a commercial organic dye, we performed an accurate resolved angle-resolved optical characterization. The plasmonic fingerprints was consequently identified as a modification of the dye photoluminescence signal in terms of both spectral redistribution and enhancement. Interestingly, by analyzing the results, an advantageous measurement configuration can be iden-tified to better engineer a suitable platform for efficiency maximization in plasmon-enhanced flu-orescence-based applications. Therefore, the coupling mechanism with the plasmonic modes, and nanostructure properties can be carefully co-optimized.

Enteric infections are a major public health concern. Detecting risk areas requires a strong surveillance system for pathogenic viruses in possible sources such as wastewater. To build an environmental surveillance system, we aimed to identify group A rotavirus (RVA) and human adenovirus (HAdV) in wastewater. We also focused on three different methods of viral concentration to determine suitability for a regular surveillance system. We screened 20 wastewater samples for HAdV and RVA using quantitative polymerase chain reaction (qPCR) and conventional polymerase chain reaction (cPCR). Sixteen posi-tives (18/20) and ten (14/20) positives for HAdV and RVA, respectively, were obtained on qPCR, representing a prevalence of 90% and 70%. Twelve (12) positives were successfully amplified. Bag-mediated filtration system (BMFS) and skimmed milk (SM) flocculation were the most consistent viral concentration methods for HAdV and RVA, respectively. Human adenovirus was identified with nucleotide identity range of 98.48% to 99.53%. Statistical analysis of positives showed that viral burden differed by site (P

The Eastern Kunlun Fault Zone (EKFZ) is located in a seismic blank area. This study investigates the hydrogeochemical characteristics of varied-temperature springs in the EKFZ to understand the relationship between fractures, fluids and earthquakes. It aids in establishing their induction mechanisms and assists in monitoring the earthquake precursors of the EKFZ. In this study, the main elements, trace elements, hydrogen and oxygen isotopes and strontium isotopes of 23 varied-temperature springs in the EKFZ were analyzed. The results reveal the source of groundwater recharge, hydrochemical types, mineral saturation, and for a select few springs indicative of geothermal activity, collected geothermal reservoir temperatures. The study also explores the relationship between earthquakes and springs, identifying sensitive chemical indicators. Based on continuous monitoring at Maqu Station, we found that before the occurrence of the Maerkang Ms 6.0 earthquake, the concentration of Cl− rose by 2.9 times, and 46 days before the Gande earthquake (Ms = 4.7), the concentrations of Na+ and SO42− significantly increased. Finally, a conceptual model of the hydrogeochemistry of springs is presented to describe the groundwater circulation in the study area. This research is of great significance for the analysis of fluid geochemistry in this area and for assessing the seismic hazards of the EKFZ.

The Epithelial-Mesenchymal-Transition (EMT) phenotype, identified as a significant clinical indicator in cancer, manifests as a biological process where cells transition from epithelial to mesenchymal characteristics. Physiologically, EMT plays a crucial role in tissue remodeling, promoting healing, repair, and responding to various tissue damages. This study investigates the impact of BNE-RRC on oral cancer cells (KB) and reveals its significant effects on cancer cell growth, migration, invasion, and EMT. BNE-RRC induces the epithelial-like morphology in KB cells, effectively reversing EMT to Mesenchymal-Epithelial Transition (MET). Extraordinarily, sustained culture of cancer cells with BNE-RRC for 14 days maintains an epithelial status even after treatment withdrawal, suggesting BNE-RRC as a potential therapeutic agent for cancer. These findings highligh the promise of BNE-RRC as a comprehensive therapeutic agent in cancer treatment by inhibiting cancer cell growth, migration, and invasion, while also orchestrating a reversal of the EMT process. The study proposes that BNE-RRC could be effective agent for cancer treatment.

Research on titanium oxo complexes (TOCs) are usually focused on their structure and photocatalytic properties. Findings from these investigations spurred our interest in exploring also their potential biological activities. In this study, we focused on the synthesis and structure of a compound with the general formula [Ti8O2(OiPr)20(man)4] (1), which was isolated from the reaction mixture of titanium(IV) isopropoxide with mandelic acid (Hman) in a molar ratio of 4:1. The structure (1) was determined using single-crystal X-ray diffraction, while spectroscopic studies provided insights into its physicochemical properties. To assess the potential practical applications of (1), its microcrystals were incorporated into a polymethyl methacrylate (PMMA) matrix, yielding composite materials of the type PMMA + (1) (2 wt.%, 5 wt.%, 10 wt.%, and 20 wt.%). The next stage of our research involved the antimicrobial activity evaluation of the obtained materials. Investigations carried out demonstrated antimicrobial activity of pure (1) and its composites (PMMA + (1)) against both Gram-positive and Gram-negative strains. Furthermore, MTT tests conducted on the L929 murine fibroblast cell line confirmed the lack of cytotoxicity of these composites. Our study identified (1) as a promising antimicrobial agent, also for producing composite coatings.

The process of establishing secure communication between devices in the Internet of Things (IoT) can be approached by using a One-time-Pad (OTP) protocol. We propose using a known secure multiparty sum protocol for generating a One-time-Pad key using true (physical) random numbers in each device (party). We implemented the proposal using ZeroC-Ice, a middleware for distributed computing. The protocol security properties were analyzed under the assumptions of the Dolev-Yao threat model.
