On the effective length of erucic and oleic acid molecules as part of the protective shell of magnetite colloidal particles
Authors: Ivanov A. S. 
Published: December 2024

Purpose. Experimental evaluation of the thickness of the protective shell thickness of magnetite colloidal particles representing a single molecular layer of oleic or erucic fatty acids.Methods. Experimental data were obtained by independent measurement of three volumetric concentrations (magnetic, solid and hydrodynamic) of magnetite particles in magnetic liquid using magneto-granulometric analysis, density measurement and titration of pure carrier liquid during peptization of dry sediment of particles. The experimental data were processed by numerical solution of the system of nonlinear equations describing the additivity of volume, mass and magnetic contributions of stabilized colloidal particles and carrier liquid to the volume, density and saturation magnetization of polydisperse magnetic liquid, respectively.Results. Four samples of magnetic liquid differing in the disperse composition of magnetic nanoparticles, three of which were stabilized by oleic and the fourth by erucic fatty acids (surfactants), were experimentally investigated. The samples were prepared by titration of pure carrier and peptization of dry sediment of colloidal particles prewashed from free surfactant molecules. For each sample, the density and magnetization curve were measured and magneto-granulometric analysis was performed. The data obtained by different methods agree with each other provided that the thickness of the nonmagnetic layer on the surface of magnetite particles is equal to 0.76 nm and the effective length of the oleic and erucic acid molecules is equal to their maximum possible values in the fully straightened state.Conclusion. At stabilization of magnetite particles by unsaturated fatty acids, the double bond, providing bending of these molecules in the basic energy state, does not play an essential role, since the thickness of the protective shell, equal to the effective length of surfactant molecules, is equal to their maximum possible length in the straightened state.
Dipole interaction of particles in magnetic fluid stabilized by a double layer of surfactant in water
Authors: Lebedev A. V. 
Published: December 2024

Purpose of the work: to study the influence of interparticle dipole-dipole interactions on the susceptibility of a magnetic fluid stabilized by a double layer of surfactant in water.Research method consists in measuring the initial differential susceptibility of a magnetic fluid depending on its concentration. Three samples of fluid based on magnetite particles, differing in the composition of the stabilizing shells, were studied. The following acids were used as the first layer of the stabilizer: lauric (C12), decanoic (C10) and octanoic (C8). The second layer of the stabilizing shell was formed by sodium dodecyl sulfate with a small proportion of the corresponding acid. Susceptibility measurements were performed on a setup for measuring magnetization curves. The concentration of the samples was determined by their saturation magnetization.Results. The concentration dependences of the initial susceptibility were measured for three samples of magnetic fluid based on magnetite particles. The obtained results were compared with theoretical models of the modified effective field of A.O. Ivanov and the average-spherical one. Both theories predict overestimated values of susceptibility in relation to experimental values. The modified effective field theory overestimates the results by 20%. The mean-spherical model - by 12%. It is shown that the correct interpretation of the concentration dependence of the susceptibility of magnetic fluid samples is possible only by approximating the ratio of susceptibility to saturation magnetization. Based on this approximation, an empirical formula in the form of a third-degree polynomial with a negative cubic term is proposed to describe the concentration dependence of susceptibility.Conclusion. Thus, the obtained results require the construction of new or modification of old theories of dipole-dipole interaction of magnetic particles in aqueous colloidal solutions with stabilization of particles by a double layer of surfactant.
Topic Modeling of Nursing Issues in the Media During 4 Emerging Infectious Disease Epidemics in South Korea: Descriptive Analysis
Authors: Kim Jungok , Yun Eun Kyoung 
Published: December 2024

Background
Emerging infectious disease disasters receive extensive media coverage and public attention. Nurse burnout and attrition peak during health crises such as pandemics. However, there is limited research on nursing issues related to repeated emerging infectious disease crises over time.

Objective
The purpose of this study was to analyze and draw implications from changes in key nursing issues reported by the news media during the outbreaks of severe acute respiratory syndrome (SARS; 2003), influenza A (2009), Middle East respiratory syndrome (MERS; 2015), and COVID-19 (2020) in Korea using topic modeling.

Methods
A total of 51,489 news articles were extracted by searching for the keywords “nursing” or “nurse” in the title or body of articles published from April 2003 to May 2021 (during new infectious disease outbreaks) in the open integrated database. The selected news articles were preprocessed then analyzed for text and structure using a 3-step keyword analysis method, latent Dirichlet allocation topic modeling, and keyword network analysis.

Results
Among the 51,489 news articles collected with the search terms “nursing” and “nurse,” 17,285 (33.6%) were selected based on the eligibility criteria and used in the final analysis. Using topic modeling, we derived 5 topics each for SARS, influenza A, and MERS and 6 topics for COVID-19. The themes commonly identified through topic modeling and keyword network analysis across the 4 epidemics were “response to emerging infectious diseases in Korea,” “demand for nurses,” “vulnerability in the work environment,” and “roles and responsibilities of nurses.” Although the topic names were the same, the meanings implied by the comprehensive keywords for each epidemic varied depending on the epidemic and the times.

Conclusions
Analysis of the identified themes and associated keyword network revealed that issues related to nurse shortages, working conditions, and poor treatment were not unique to the COVID-19 pandemic but rather recurring themes from previous epidemics. Our findings can be used to inform strategies to improve the professional roles, work environment, and treatment of nurses during health crises. Suggestions for future nursing-related policy impact and change research are also provided.

Authors: M. Swetha  , G. Appa Rao  
Published: December 2024

Internet of Medical Things (IoMT) is a fast-developing area that includes the use of connected medical devices to enhance patient care and expedite the procedures involved in the delivery of healthcare. Concerns about the safety and confidentiality of patient information are a roadblock to the broad use of telemedicine technologies like IoMT. Encryption is an essential part of IoMT security, and there is a wide variety of encryption methods that are used to safeguard sensitive patient data. This work implemented a hybrid ensemble lightweight cryptosystem (HELC) using probabilistic rivest cipher 6 (PRC6) encryption and modified feistel block cipher (MFBC) approaches. Initially, the data from users are applied to PRC6 encryption, which is symmetrical encryption and provides security at in abstract level. So, to provide more security to data, the MBFC is applied to PRC6 outcome. Then, the resultant data transferred over the IoMT environment to the destination. Finally, the MBFC decryption and PRC6 decryption operations are performed at receiver side, which resulted in decrypted outcome. The simulations results show that the proposed HELC consumed 0.0021 seconds of encryption time, and 0.000276 seconds of decryption time, which are lesser as compared to other approaches.

Published: December 2024

This study analyzes various machine learning techniques for detecting attacks against Routing Protocol for Low-Power and Lossy Networks (RPL), a routing protocol commonly used in Internet of Things (IoT) applications. RPL is often employed in IPv6-based IoT applications that require low power consumption and limited bandwidth. The research reviews recent literature examining attacks on RPL-based networks and utilizes the ROUT-4-2023 dataset for detecting routing attacks. This dataset, created using the Cooja simulator, encompasses four types of routing attacks: Blackhole Attack, Flooding Attack, DODAG Version Number Attack, and Decreased Rank Attack. The attack types are detected using machine learning techniques like AdaBoost, KNN, Random Forest, Decision Tree, and Bagging. In the combined dataset, the Decision Tree and Bagging algorithm exhibited the highest performance with a 99.99% accuracy. To create a more accurate representation of the real world, we incorporate a 10% level of noise into the dataset. On the noisy dataset, Random Forest algorithm performed the best with about 84.80% accuracy. The high accuracy show that the employed methods can be effectively used as an Intrusion Detection System (IDS) to protect IoT networks. As a result, this study demonstrates that machine learning techniques offer a promising approach for detecting routing attacks in the RPL protocol. The findings provide useful information for researchers and practitioners in the field of IoT security. This study contributes to the potential of machine learning-based algorithms to enhance the security of IoT networks and contributes to future research in this area.

Published: December 2024

Background: Research in literature have examined the leadership styles of nurse managers. However, no qualitative study based on metaphors could be found to determine the perceptions of nurses regarding their managers in depth and without limitations where they could freely express their opinions. The purpose of this study is to determine the perceptions of nurses regarding their nurse managers with the help of metaphors.
Methods: This study used a mixed methods approach to including both quantitative and qualitative research methods. This study was conducted in a total of 118 nurses between August and November 2022. The data were collected as online by the researchers through personal information form and an questionnaire including a semi-structured open-ended form. In the first part of the questionnaire, questions about socio-demographic characteristics were included, and in the second part, the sentence "My nurse manager is like…, because…" was included to determine the metaphors developed by the nurses about their nurse managers. The nurses’ answers to this question were analyzed with content analysis.
Results: The metaphors formed by the participants regarding their nurse managers were gathered under 1 positive theme and 1 negative theme covering 20 categories (13 positive categories and 7 negative categories). In the study, 94 different metaphors were identified, and 53 of these were positive metaphors, while 41 were negative metaphors. In the positive sense, the participants perceived their managers as trustworthy, supportive family members, individuals who restore/coordinate, individuals who protect/defend, hardworking, source of happiness, just/fair, source of power, source of support, problem-solver, nutrition, source of knowledge, and guiding. In the negative sense, the participants perceived their managers as harming/harmful, passive, unstable/inconsistent, coercive/oppressive, opportunistic, useless, and biased.
Conclusion: The results of this study showed that most nurses perceived their managers positively.
Schriftexegese als Voraussetzung für Emil Brunners frühe dialektischen Soteriologie anhand des Beispieltexts Lk 15,11–32
Authors: STEINER Fabienne 
Published: December 2024

Dialectical Soteriology using the example of Lk 15:11–32. In my article, I would like to show Emil Brunner’s early thoughts and statements, which he reveals in his sermons in Obstalden. These sermons are still unknown and unpublished. It is mostly claimed that Brunner entered in a modern and dialectical phase because of his colleague in the Reformed Church, Karl Barth. The truth is that they later had intense discussions about theses and antitheses in their dialectic phase. Brunner, however, formulates new dialectical thoughts earlier than Barth – for example, already in 1917 on dialectical soteriology by using the text of Lk 15:11–32. In his sermons, he reflects several arguments of modern theology and defines, for example, God as thesis, lost person as antithesis, and saved person as synthesis. A detailed exegesis leads in the resolution of what follows from an encounter with God, namely being at home in safety.

Is Hunting allowed on Sundays? Rules for the Seventh Day. The present study is part of a longer research project which aims at presenting the international movement for the sanctification of Sunday between 1875 and 1878 in the light of the periodical Evangyéliomi Protestáns Lap (EPL), founded and edited between 1875 and 1878 by Ferenc Balogh (1836–1913), a Reformed church and dogmatic historian and professor of church history in Debrecen, supplemented by domestic news from the periodicals Protestáns Egyházi és Iskolai Lap (PEIL) and Erdélyi Protestáns Közlöny (EPL). Church associations, tenders, religious and secular newsletters, publications and conferences played a major role in the international struggle for a Sunday off. This is how the International Sunday Movement came into being. The professor from Debrecen also supported it and kept the issue of Sunday celebration on the agenda with his Evangyéliomi Protestáns Lap. The issue was not only examined from an ecclesiastical point of view at the time, but its social and health implications were also pointed out. The issue of Sunday rest was of great interest. The problem is not a recent one, but the transformation of economic life has brought the issue to the fore more strongly. Most of the problematic Sunday working has come from the railways, industry, and commerce, with little mention of agriculture.
In this paper, we examine what church life was like on Sundays, what kinds of work and activities were banned by church and piety movements at home and abroad, and what role was played by the example and personal responsibility of the leading classes. Attention is drawn to specific phenomena that seem contradictory to people today such as the fact that hunting was forbidden on Sundays, but not horse riding and exhibitions. We will show how the time of worship was protected, how Sunday trips, excursions, visits to museums, galleries, and public gardens were judged, and what the movement expected of the state. What were the practical consequences of Sunday drinking and what were the counter-effects of Sunday bans.

“The Lord’s Holy Church Is a Field of Blood Today in Our Beloved Nation.” Protestant Martyrdom in a Manuscript Sermon from the Teleki Archives (1675). The sermon under scrutiny is found in the archival material of the Count Teleki of Szék family (P 658), kept in the National Archives of Hungary. It is not unknown to research, although it has mainly gained interest before as a source for the history of books and libraries. The 13 manuscript pages contain the date 1675 and the name of István Nemes, as well as reference to the Reformed College of Enyed/Aiud, but the author of the sermon is unidentified. The Biblical text used is the Song of Songs 2:2, and the topic is Protestant martyrdom. Similarly to other books of Protestant martyrdom (Foxe, Raabus, Crespin), it traces the persecution of the true Church from the Old Testament fratricide to his own time. It starts with the murder of Abel, going through the Egyptian captivity of the Jews, recalling the story of the prophets murdered by Jezebel, and the persecution of Christians under the Roman Empire, ultimately leading to the sacrifice of Christ. This list appears in a similar way with other authors of this decade of mourning too (Mihály Szőllősi, István Szőnyi Nagy); what is more, Szőllősi was Teleki’s court pastor until 1674. The sermon connects the pain felt over the trial of the pastors and teachers condemned to the galleys, the fleeing of the Reformed College of Sárospatak, the seizure of Protestant churches, and the expulsion of several pastors with the grievances of “our beloved nation”. Through this, the sermon is also a document of the political connections of the Transylvanian Reformed elite and the fugitives in Hungary, as well as the piety movements that underlie these connections.
The Psychological Interpretation of the Grieving Process
Authors: KIRÁLY Lajos 
Published: December 2024

This paper presents the psychological interpretations of the grieving process and examines how professionals from Sigmund Freud, Melanie Klein, Erich Lindenmann, Gerard Caplan, Alaine Polcz, and Emőke Bagdy through Erwin Ringel to Sara Bodó have interpreted grief. We find that all of them include in their definitions the concept of loss, which is “a reaction to the loss of a loved one or an abstraction that has taken place”. We then examine the differences between male and female grief, the ambivalent feelings associated with the fact of death, and the family dynamics that all testify to the family as the primary support when experiencing grief, pain,[1] and loss. In what follows, I will write about the linear stages of the grieving process: anticipation, shock, controlled and awareness stages, along with stages of uprising emotions, search and separation, and adaptation.

The Role of Visions in the Process of Change and Re-visioning Life. A vision is a possible imagined version of our future. In this essay, we look more generally at the role of hope and vision in our personal change and address the particular path to change that Christianity offers. Human life needs a structured set of goals, where smaller, short-term goals (micro-visions) and larger, long-term goals (big visions) are interlinked. Micro-vision motivates us on a daily basis, while big vision gives our lives long-term direction and meaning. Being able to find the big goals does not only prioritize the smaller ones, the projects of our lives but can also give us a sense of flexibility to let go of the tensions of everyday life, because we can see beyond the days, weeks, years and see the significance of the present in terms of the big picture. The vision of a possible and desired future can give us the strength to withstand the tensions of the present.

Abstract
Potato is one of the main agricultural commodities and has high economic value. Yield is a trait that becomes a benchmark for user (industry and farmers) in selecting and developing varieties. The selection of superior newly potato somaclones using combined analysis and sustainability index (SI) is still underreported. This study aimed to identify the effect of genotype by environment (growing season) interactions (GEIs), as well as to select superior potato somaclones. The research was conducted in three years (2020 ‒ 2022) in Lembang, West Java, Indonesia. There were 38 somaclones tested in the field, consisting of 37 gamma ray-derived somaclones and one control genotype. The somaclones originated from commercial varieties Agria, Granola, Repita, and Vega. The field trial used a randomized block design that was repeated three times in each year. GEIs were calculated based on a combined ANOVA. Yield stability was assessed using the combined analysis (parametric and non-parametric), genotype plus genotype by environment interaction (GGE) biplot, and sustainability index (SI). Potato somaclones (G), seasons (E) and GEIs were found to have highly significant influence on yield (P < 0.01). According to the combined ANOVA, the GEIs impact accounted for 37.38% of the yield’s total sum of squares. Combining parametric and non-parametric measurements, seven somaclones, P3, P4, P5, P6, P8, P9, and P26, were selected. GGE biplot selected five stable somaclones, namely P3, P4, P22, P23, and P26, while SI selected eight high-yielding and stable somaclones, namely P3, P4, P5, P8, P13, P16, P26, and P32. Based on various stability measurements, three genotypes have been identified as the superior somaclones, namely P3, P4 and P26. This analysis can assist in selecting activities to determine superior somaclones.
