Piezoresistive response of geopolymer pastes activated by silica fume-derived alkaline solution
Authors: Muthu Murugan , Sadowski Łukasz
Published: March 2024

This study examined the self-sensing performance of metakaolin-based geopolymer paste samples activated by an alkali activator, which is a solution mixture of potassium hydroxide and silica fume (SF). Their piezoresistive response under repeated compressive loads was found to improve with increasing SF content. It was found from their XRD, SEM, and FTIR results that the change in the SF content did not alter the phase composition of the geopolymer matrices. The factorial change in the electrical resistivity of geopolymer samples with a maximum SF content was calculated to be about 0.024. Their pore solutions were detected to be mainly filled with potassium and silicon ions due to the use of higher concentrations of SF particles. The UV spectrophotometry measurements of this study confirm that all the geopolymer samples displayed semiconductor behaviour. The SF-derived alkaline activator can enable the self-sensing character of geopolymer-based concrete, which isenvironmentally friendly and has recently shown great potential to monitor structural integrity under applied external loads.

Authors: Jasiński Radosław , Skrzypczak Izabela , Leśniak Agnieszka , Natividade Eduardo
Published: March 2024

The knowledge of impacts and the load-bearing capacity of unstrengthened/strengthened structures is a crucial source of information about the safety of masonry buildings near deep excavations, especially in dense urban areas. Incorrect calculations made for such designs can seriously affect not only an analyzed object, but also the adjacent buildings. The safety of masonry buildings can be determined by many factors that are closely related to the hazards presented during the performance of deep excavations. These factors are at first identified and then prioritized. The AHP process in the multi-criteria analysis was used to support the decision-making process related to the verification of factors affecting the safety assessment of masonry buildings in the area of deep excavations. The proper design of building structures, including the verification of the structure strengthening near deep excavations, was found to be the most significant factor determining the safety of such buildings. The methodology for proceeding with the verification of ultimate (ULS) and serviceability (SLS) limit states in accordance with the literature data, current regulations, such as Eurocode 6 and other design standards, and know-how of the authors, described in this paper was the next stage of the discussed analysis.
Occlusion-aware collision avoidance trajectory planning with potential collision risk assessment for autonomous vehicle
Authors: Qian Yubin , Deng Chengzhi , Xu Jiejie , Qu Xianguo , Song Zhenyu
Published: March 2024

Motion planning for autonomous vehicles relies heavily on perception and prediction results to find a safe, collision-free local trajectory that adheres to traffic rules. However, vehicle perception is frequently limited by occlusion, and the generation of safe local trajectories with restricted perception is a significant challenge in the field of motion planning. This paper introduces a collision avoidance trajectory planning algorithm that considers potential collision risks, within a hierarchical framework of sampling and optimization. The primary objective of this work is to generate trajectories that are safer and align better with human driver behavior while considering potential collision risks in occluded regions. Specifically, in occlusion scenarios, the state space is discretized, and a dynamic programming algorithm is used for a sampling-based search to obtain initial trajectories. Additionally, the concept of a driving risk field is introduced to describe potential collision risk elements within the human-vehicle-road environment. By drawing inspiration from graph search algorithms, potential collision risk areas are accurately described, and a cost function is proposed for evaluating potential risks in occluded regions. Drivers typically exhibit conservative and cautious driving behavior when navigating through occluded regions. The proposed algorithm not only prioritizes driving safety but also considers driving efficiency, thereby reducing the vehicle's conservativeness when passing through occlusions. The research results demonstrate that the ego vehicle can actively avoidblind spots and tends to move away from occluded regions, aligning more closely with human driver behavior.
On applications of quasi-Abelian Cayley graphs to Denial-of-Service protection
Authors: Girejko Ewa , Malinowska Agnieszka
Published: March 2024

This paper addresses the problem of designing secure control for networked multi-agent systems (MASs) under Denial-of-Service (DoS) attacks. We propose a constructive design method based on the interaction topology. The MAS with a non-attack communication topology, modeled by quasi-Abelian Cayley graphs subject to DoS attacks, can be represented as a switched system. Using switching theory, we provide easily applicable sufficient conditions for the networked MAS to remain asymptotically stable despite DoS attacks. Our results are applicable to both continuoustime and discrete-time systems, as well as to discrete-time systems with variable steps or systems that combine discrete and continuous times.
The common good from an economic perspective: Insights from EU policies during the COVID-19
Authors: Szypulewska-Porczyńska Alina , Zduńska-Leseux Edyta , Horodecka Anna
Published: March 2024

This paper delves into the diverse conceptualizations of the “common good” within the economic discourse and scrutinizes their implications for European integration during the pressing COVID-19 pandemic. Employing a comprehensive literature review, policy analysis, and case study examination, it explores the manifestations of the common good in the context of European Union policies. Two key interpretations emerge from our investigation: the first presents the common good as an ultimate objective, seeking a balance between individual and collective interests achieved via adept economic governance; the second considers it a continuous process underpinned by the principles that direct the journey toward such a balance. Our findings reveal that the EU’s response to the COVID-19 crisis led to shifts in fiscal policies and innovation strategies. The research outcomes demonstrate a marked transition in the EU’s approach, with a stronger focus on social welfare, environmental sustainability, and collective well-being.

Published: March 2024

The covid-19 pandemic is one of the health crises that demand effective communication and timely, accurate, and culturally sensitive communication to reach coordinated and more effective responses. Regarding this function, communicative leadership becomes critical in reaching the success of a health crisis, particularly among local communities which are frequently associated with resistance towards health initiatives. This research is intended to explore the communicative leadership performed by local leaders in managing covid-19 pandemic from 2020 to 2022. To meet this aim, the present study employed interviews with 6 local leaders in Kabupaten Pasuruan, Jawa Timur as informants. This research revealed that in responding health crisis due to covid-19 pandemic, leadership involved communication to construct and negotiate meaning through shared narratives about covid-19. This leadership had been performed to help communities in the sense-making process about the pandemic through a series of strategies comprising (1) operating religious frame and local values to construct a shared reality about covid-19 pandemic and how to respond to it, (2) providing narratives as the evidence, (3) performing openness, presence and empathy. This research also found that maintaining sustainable coordination with the authorities is performed by local leaders to assure communities about the pandemic response plan, thus, community involvement in covid-19 measures could be developed easily. This study confirmed some previous research highlighting the importance of faith-based organizations (FBOs) in communication intervention in the health context and research on the importance of narrative to persuade people to adopt new health behaviours.

Study on millenial generation is essential to conduct since in the near future the millenials will dominate the workforce and hold strategic positions in industry. According to references, millenials are well-known for their reluctance to stay working in one place for a long-time period. Many speculations have arisen to explain the issue, whether it is caused by their positive as well as the negative characteristics. This study aimed to investigate the factors affecting millenial’s intention to stay. Three levels of context were involved as researched variables, namely work passion, quality of work life, and work engagement as mediator. Quantitative and non-experimental study was applied to test the hypotheses. Using convenience sampling technique, 125 millenial workers in Jakarta, Indonesia, were recruited and completed the online questionnaires. The questionnaires to measure the researched variables are Intention to Stay Scale, Work Passion Scale, Quality of Work Life Scale, and Utrecht Work Engagement Scale (UWES). Regression analysis reported that intention to stay was significantly affected by work passion and quality of work life. Moreover, work engagement was also proven to be a significant mediator that bridged the association between intention to stay and both of independent variables, namely work passion and quality of work life.

Published: March 2024

Indonesian people are becoming more aware of the significance of skincare, increasing the demand for beauty care products. As a result, the frequency of purchasing skincare products in Indonesia has also risen. Local Indonesian skincare is a popular choice among the public. The variety of local skincare products encourages competition among companies to market their products. In the times, marketing through social media is increasingly popular to interact directly with customers. Indonesia ranks second in the world, with the number of TikTok users reaching 109.90 million. This research uses the S-O-R Model to analyze the positive influence of Marketing Activities on social media on Brand Loyalty, with the mediating role of Customer Brand Engagement and Brand Trust. The hypothetical relationships in the proposed model are tested using Structural Equation Modeling (SEM). Of the total respondents who were TikTok users for six months or more, 87.3% were women. This research aims to understand how social media marketing activities (SMMA) impact brand loyalty (BLO) for local skincare brands in Indonesia. It also considers the mediating roles of customer-based equity (CBE) and brand trust (BTR) in this relationship. The results of hypothesis testing showed a significant positive influence on all variables tested. The role of mediation has also proved significant, albeit with varying degrees of influence. Some variables tend to have a low influence on Brand Loyalty, while the most significant influence is seen in the influence of SMMA on Brand Trust. Thus, this study has important implications for local skincare companies in developing effective marketing strategies to build strong brand loyalty and increase customer trust in the brand.

attention and vigilance. That's why disaster mitigation needs to be disseminated to all levels of society. One area that has a high level of vulnerability is Kulon Progo is a case study with a descriptive type in this research. Recorded in 2019 having 53 landslide-prone areas in 5 sub-districts. To anticipate victims, the Regional Disaster Management Agency (BPBD) of Kulon Progo Regency formed 3 Disaster Response Villages as bottom-up disaster mitigation pilots, one of which is Kalirejo Village. This effort is interesting in examining how communication patterns are carried out in natural disaster-prone areas (Kalirejo Village) in mitigating natural disasters. This study is qualitative and involves several elements including Kelurahan government officials, self-help groups, disaster risk reduction forums, volunteers, and residents who represent stakeholders related to mitigation. A qualitative approach is used to deepen understanding through observation, interviews, and focus group discussions. Data analysis uses an interactive model recommended by Miles and Huberman. The main findings of the study show that the most frequent natural disasters are landslides and floods. This is caused by the topography which causes unstable soil conditions so that it easily causes landslides when rainfall is high. The dominant communication pattern in terms of natural disaster management/mitigation is bottom-up, from the community to the Village, Kapanewon, and Regency Governments as well as BPBD. However, ritual communication patterns, both based on local traditions and wisdom as well as those with nuances of religious teachings, are still sustainable and ongoing.

Authors: Bajari Atwar , Suryana Asep , Wahyudin Uud , Mulyana Slamet , Rakhmaniar Almadina
Published: March 2024

The debate surrounding the 2024 General Election in the virtual space, such as social media, has led netizens to exchange hate speech and heavy criticism regarding their respective support. Two groups have emerged: government supporters highlighting the successes of President Joko Widodo and those shifting their support to Anies Baswedan after Prabowo joined the government. Over time, this phenomenon has led to the proliferation of hate speech based on identities such as religion, ethnicity, and fanatical groups, potentially dividing public opinion. This study aims to explain the emergence of hate speech and the forms of hate speech based on identity politics leading up to the 2024 General Election. This study employs virtual ethnographic analysis (Virtual Ethnography) to observe tweets or statuses on selected accounts and the comments that arise from those tweets. The objects of analysis are the trends of words and phrases and the content within observed sentences or paragraphs. The research findings have been presented in the form of tabulation and categorization. The results show that comments and statuses containing hate speech always create bidirectional and multi-directional communication models among users. Hate speech often uses phrases and keywords that lead to insults, malicious accusations, curses, and accusing the opposing party of being stupid and evil. Based on this study, social media users must realize that the presidential campaign is a time to have different choices but remain aware of the same nation. Users need to develop an awareness of social media ethics. Enforcing rules against those who spread hate speech is key for every actor involved.

As something unique, local culture can be utilized in various fields, one of which is tourism. The development of the tourism industry is characterized by several things, for example there is an increase in community participation to advance the local tourism industry, and the use of the creative economy. This research itself was carried out by looking at the potential that Indonesia has in the tourism and creative economy sectors which still have great potential to be developed further while still supporting the preservation of Indonesia's local culture. The research was carried out at a location in East Sumba, because it has a natural attraction for tourism which is already worldwide, but its development so far has not been optimal. Apart from having natural potential for tourism development, Sumba also has local culture and creative economy products, such as woven fabrics. This research was conducted with the main aim of producing a model for the development of tourism and creative economy based on local culture. This research itself will focus on the use of local culture in the tourism sector and the creative economy in tourism communication studies. The research was conducted using a qualitative approach and case study method. Data was obtained through FGD and interviews with resource persons. Based on the research results, it can be concluded that East Sumba has potential in terms of tourism development, the potential is in the form of natural resources, creative economic products, local culture and infrastructure suggestions. Developing this potential must receive support from the government in the form of development and policy making that favors local communities. Apart from that, tourism development also requires the development of human resources, which therefore requires collaboration between the government and local communities.

Published: March 2024

This study analyzes the characteristics of real estate transactions from 2017 to 2022, distinguishing between transactions within the region(si, gun, gu), adjacent regions, and non-adjacent regions. It uses social network analysis methods to derive the characteristics of the network and the actors (si. gun, gu). The research results show that about 50~55% of the collective building transactions occur within the region, about 15% between adjacent regions, and about 30% between non-adjacent regions. As a result of analyzing transactions between non-adjacent regions through a network approach, most regions belong to one real estate transaction network centered on the metropolitan area, and many regions can influence each other in real estate transactions. The significance of this study lies in presenting a new approach to real estate transactions by analyzing real estate transactions between cities and counties in Korea through a social network approach, and deriving policy implications through this.

Juvenile delinquency is at a worrisome rate in every part of the world. The juvenile offenders themselves are in a vulnerable period of development while also living in the difficult situation of detainment. However, challenges that juvenile offenders face in correctional institutions, how they construct their reality about detainment as well as their mental health needs have not been widely addressed. Research on juvenile offenders’ psychological experiences is not sufficiently documented and expressed. Hence, much less attention or programs were directed to address these obstacles. This review aims to present the psychological experience of juvenile offenders in correctional institutions. The systematic review examined qualitative studies over a 10-year period that were published between 2012 and 2022 from five databases, resulting in 16 articles mostly indexed in SCOPUS. The study utilized the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework and the narrative synthesis approach. Moreover, the findings provide empirical evidence that juvenile offenders’ psychological experiences (i.e., negative and positive emotions) are evident throughout their detainment, and interaction with staff and peers is crucial in defining it. Therefore, some of the challenges of living in correctional institutions include the feeling of boredom, strict regulations, and lack of care. Hence, education on adaptive coping, expanded vocational opportunities, and programs providing warmth, safety, and positive environments are crucial to rehabilitating offenders.

Early marriage in Bawean Island involved long-term experiences and understanding of actors’ sociocultural. The phenomenon of early marriage has never been studied using social construction. This research aims to reveal the social construction of early marriage through the dialectical situation of externalization, objectivation, and internalization in early marriage. This research uses a qualitative case study approach by collecting data through participant observation, in-depth interviews, and documentation. This research was conducted on Bawean Island with 31 participants throughout 2023. The results of this study were as follows: first, actors perceived and interpreted early marriage as avoiding social sanctions (out-of-wedlock pregnancy) to avoid social embarrassment; economic solutions; religion does not prohibit early marriage; avoiding religious sanctions; and early marriage is not considered to violate state law and can be legalized. Second, early marriage continued because parents and other social organizations, such as religious leaders and hamlet heads, acquired social capital. The role of hamlet heads in supporting the administration and testifying in the marriage dispensation trial is regarded as objective, allowing the state to legalize early marriages. In addition to continuing practical programs aimed at female actors, outreach to the entire family about the dangers of early marriage, and adding psychological and health expert witnesses to trials, special consideration must be given to social capital, which needs to be taken into account in future research.

Soil microbes (bacteria) are more widely used for various types of pollutants while the soil fauna acts as a chunk of solid material which will then be broken down by microbes.
The concept of creating an electric field strength meter with the determination of the error of the measurement result and the distance to the field source
Authors:   Omsk State Technical University, Biryukov S. V.
Published: March 2024

A new concept of constructing an electric field strength meter is considered. The concept lies in the fact that along with the measurement of the modulus of the electric field strength vector, the error of the measurement result and the distance to the field source are subject to simultaneous instrumental determination. The field meter is based on a new dual sensor and a method for measuring the electric field strength. The ability of the measurement method to determine the error and the distance to the field source is provided by a dual electroinduction spherical sensor. A feature of a dual sensor is the ability to simultaneously output two field strength values measured at one point, obtained with errors of different signs. This feature made it possible to obtain the measurement result as an average value and two measured values, and thereby reduce the measurement error. The presence of two simultaneously measured values of the field strength also made it possible to obtain an empirical formula for determining the relative distance to the source at each measurement point. The obtained values of the relative distances made it possible to determine the error of the measurement result and the distance from the center of the sensor to the field source using known formulas. The possibility of a field meter to simultaneously instrumentally determine the error of the measurement result and the distance to the field source is considered for the first time.

The development of television systems is an important factor for many industries involved in the acquisition, processing, storage and transmission of images. Today, an urgent task in the use of such systems is to improve the quality of images obtained using digital photo and video cameras. To solve this problem, digital recursive-separable smoothing filters can be used. The paper describes the process of operation of the algorithm for changing the size of the scanning multi-element aperture of a smoothing trapezoidal recursive-separable filter for digital image processing. The results of evaluating its performance relative to the same algorithm implemented through classical two-dimensional convolution for various sizes of test images are presented. The influence of the aperture size of the developed filter on the change in the signal-to-noise ratio is assessed. The algorithm is implemented in the MATLAB computing environment.

The presented work provides a detailed analysis of modern approaches to creating elastoplastic models of surface crack growth that take into account the influence of the type of biaxial loading on the development of stresses and strains at the crack tip and, accordingly, on the crack growth rate. The use of the plastic stress intensity factor as a characteristic of resistance to cyclic deformation and fracture for biaxial loading conditions is substantiated. Continuum plasticity models are proposed to simulate the elastoplastic behavior of metal using numerical methods and, in particular, the finite element method.

The article presents theoretical and practical aspects of improving the designs of existing separation subsystems using the results of historical and patent information studies used to detect and extract ferromagnetic bodies in a flow of multicomponent non-magnetic lumpy, granular and finely divided and friable media. A new energysaving technological approach proposed with the effect of synchronously improving the performance of the transport and technological system and reducing the cost and energy costs during its operation, in particular in the material flow separation subsystem. A subsystem for the separation-detection of metal fragments in a non-magnetic granular medium proposed for the development of signaling and current control devices in extracting windings. To increase the extraction capacity during the purification of non-magnetic granular media, a design of a combined iron separator proposed. Mathematical modeling of the operation of the electromagnetic system of the combined iron separator of the transport system is carried out, on the basis of which a mathematical model of the magnetic field in its working area is proposed, which makes it possible to determine the extracting force from the windings with and current. An experimental verification of the results of theoretical studies of pulsed magnetic extraction of ferromagnetic bodies from a granular medium is carried out.
