Out of Sight but Still In Mind: Making ‘Invisible’ Cyber Threats More Salient Via Concrete Analogies
Authors: Pyke Aryn , Bouchelle Rebecca , Uzhca David
Published: June 2023

It can be easier to conceive of and anticipate physical threats than cyber threats. Cyber threats can involve unseen remote hackers, and capitalize on invisible wireless signals as vectors. As such cyber threats are often out of sight and out of mind. How can we make these abstract, 'invisible' threats more intuitive and salient? We employed concrete analogies to enable future Army Officers to better anticipate cyber threats in tactical contexts. Modern multi-domain battle involves not only physical threats like fire fights and improvised explosive devices (IEDs), but also, increasingly, cyber threats. For example, the enemy may jam, intercept or track communication signals, hack into computing systems to exfiltrate or alter information, and/or hack equipment with electronic and autonomous components (including navigation systems, drones and robots). To ensure readiness, all soldiers, (not only cyber specialists) must have some awareness of this 'threatscape'. We developed the problem anticipation task (PAT) to gauge the degree to which participants would anticipate cyber as well as non-cyber tactical threats. They read a hypothetical mission description and tried to anticipate various problems that could arise. The mission explicitly mentioned several cyber-vulnerable components (e.g., radios, navigation systems, drones, biosensors, cell phones). Prior research using a sample from the same population indicated that about 40% of subjects did not anticipate a single cyber threat (Pyke, Ness, Feltner, in press). The current research used the PAT as a pre- and post-test and included an intervening intervention. Experimental subjects read a passage about a fictitious historical mission set in the 1800s. The version of the passage presented to the experimental group included historical issues (e.g., carrier pigeon intercepted by enemy) that were intended to be analogous to modern cyber-related issues (e.g., wireless communications signal intercepted/tapped by enemy). The intervention for the comparison group involved a passage describing historical issues (e.g., horse losing a shoe) that were intended to be analogous to modern non-cyber related issues (e.g., vehicle breakdown). Note that the link to the corresponding modern situation was not made explicit to the participants, they were just exposed to a historical situation that could lend itself to being analogous to a modern cyber situation. For the experimental group (but not the control) there was a significant gain in the percent of participants who were able anticipate one or more cyber issues. Thus, concrete analogies can serve to make 'invisible' cyber threats more intuitive and easier to anticipate.
Mixed reality control of a mobile robot via ROS and digital twin
Authors: Wittenberg Carsten , Bauer Benedict , Schloer Nicholas
Published: June 2023

In recent years, mobile robotics has been increasingly used in agricultural production due to technological progress and increasingly powerful IT systems. Today, drones are already being used to spray agricultural areas with pesticides, for example. In the field of mobile robotics, control is currently based primarily on a controller or an app on a smartphone or tablet. If spatial target coordinates are to be specified, which the robot has to control, both systems quickly reach their limits. Using a mobile robot developed for the management of monocultures, this paper explains how spatial target coordinates can be approached with the help of a digital twin, ROS and a mixed reality interface using an MS HoloLens. The fusion of the technologies accordingly opens up new possibilities for a "human-robot interface".When developing an operating concept for the mobile robot, problems quickly arise regarding the determination of coordinates. The explanation for this is: The coordinate systems of the HoloLens and the mobile robot are not identical and, above all, are not known to the user. However, these obstacles can be eliminated by using a Digital Twin, which is displayed on the real robot using the HoloLens. By this measure, the coordinate system of the mobile robot is made known to the mixed reality device and it is possible to send the position coordinates as an offset to the current position of the robot. However, it should be noted that Unity (on the HoloLens) uses the left-hand rule, while ROS (on the robot) uses the right-hand rule. Therefore, the position data must be transformed accordingly.The same applies to the rotations, which must be converted as the equivalent of the coordinate transformation. Afterwards, the converted pose, which is now available in a "base_link" frame, can be transferred to the mobile robot via ROS.For the communication between the mixed reality device and the mobile robot, a ROS Bridge Client, which provides the messages in JSON format, is used. When sending target poses, it is important to note that the current time-stamped must be mandatory included in the message, otherwise the transformation from the "base_link" frame will not be converted to "map" coordinates. The transformation of the pose must also be done for the visual solution of the path planning. For the visualization, a distinction is made between the local and the global path planner A digital twin is superimposed on the real mobile robot for control and path planning. In the course of the project, problems with accuracy or performance have been discovered. In the intended application area - agriculture - the performance is weighted higher after an evaluation, so that slight position inaccuracies are accepted. The paper presents the concept as well as the interaction possibilities between the human and the mobile robot via the digital twin.
Community interface of gated communities as a docking space for future unmanned distribution
Authors: Cai Yanni
Published: June 2023

The research aims to integrate the system of unmanned logistics with community design to help communities cope with major public health crises. Through literature research and field investigation, it is found that the lack of community docking space and personnel is an important reason why unmanned logistics cannot be applied on a large scale at present. The study also observed that the last-mile delivery during the epidemic was physically hindered by the walled boundary of gated communities in China, which also made this type of space become a temporary transit place. It has the potential to become the touchpoint to integrate unmanned distribution and community space. This research uses the interface of the community as the transition medium for future unmanned distribution with the modular docking device attached to it. After the epidemic, such space can also be expanded into a diversified space with community social and entertainment attributes. Through the socialized development of logistics infrastructure, it can establish an interface-based logistics cooperation network to utilize the labor force active near the interface space and help the node connection of unmanned vehicles. In conclusion, this research can realize the diversification and socialization of unmanned logistics in the future, integrate distribution facilities into the community design through community interface, and promote the resilient development of community logistics to respond to the public health crisis.
I Want to Ride My Bicycle? - User Requirements and Usage Scenarios for Electric Cargo Bikes
Authors: Philipsen Ralf , Biermann Hannah , Himmel Simon , Ziefle Martina
Published: June 2023

The use of electric cargo bikes (ECBs) can be a solution for emission-free and sustaina-ble mobility as well as for relieving inner cities, which often suffer from air pollution, noise, congestion, and parking pressure caused by conventional cars. However, the successful integration of ECBs into urban transportation systems is highly dependent on their acceptance and adoption by users. Therefore, this paper uses an empirical survey (questionnaire study, N=180) to explore how different trip purposes and levels of prior experience influence the willingness to use ECBs. It could be shown that the perceived importance of individual ECB attributes, such as quality, comfort, or handling, is largely independent of previous experience and trip purposes. In terms of willingness to use, trips to bring children do not differ from shopping trips. Both find higher approval than the use of ECB on the way to work. The influence of previous experience can be seen in the fact that those who have used cargo bikes before show a higher general willingness to use them, but also a very low willingness to use them in adverse weather conditions. For personal attitudes, such as environmental awareness, only weak effects were found regarding the willingness to use.
Driver Monitoring Systems: Design Considerations for Aging Drivers
Authors: C Mersinger Molly , Graff Daniel , Van Ommen Carmen , Ehrenfort Sabrina , Talley Jamie , Chaparro Alex
Published: June 2023

A number of automotive manufacturers including General Motors and Tesla offer vehicles with advanced semi-autonomous driving functions that the driver is expected to monitor. Monitoring by the human driver is essential given that these systems are known to have difficulty handling driving situations that human drivers negotiate easily. The human operator must, however, adjust to this new supervisory role of monitoring system operations rather than traditional driving. Additionally, drivers may trust the automation too much, believing the systems are more capable than they are and not actively monitor the operation of the semi-autonomous systems. This belief may be engendered by the use of terms like “self-driving” or “drive pilot” in vehicle marketing materials. In response to these concerns, automotive manufacturers have developed driver monitoring system(s) (DMS) that assesses the driver’s attentional engagement in the driving process and alerts them when it determines they are not attending to the vehicle’s operation. Driver attention is assessed by monitoring their eye-gaze direction, head pose, steering wheel torque input, and facial action units. During the aging process, there are many changes in perceptual, cognitive, and musculoskeletal systems that may not have been addressed in the design of the DMS. An example of these limitations include hearing or vision impairments, which could make perceiving warnings presented by the DMS more difficult. The potential limitations of DMS will be discussed, as well as ideas for future research, which encourages consideration of older adults in interface design and discusses trends in technology adoption by older adults.
Service Quality of Inclusive, Sustainable and Resilient Community Transport Systems
Authors: Simoes Anabela , Suen Ling
Published: June 2023

The paper aims at presenting a conceptual framework integrating a Service Quality Assessment Concept in a methodological approach towards inclusive, safe, sustainable, and resilient transport systems to accommodate everyone’s mobility needs. Despite the improvement of public transport systems around the world, many users perceive: 1. Poor accessibility in most public transport systems; 2. Existence of physical barriers to free mobility in urban walking areas; 3. Increasing frequency of unexpected incidences as new norm in this 21st century (floods, earthquakes, terrorist attacks, pandemics, etc.).Furthermore, as transport operations are dynamic, increasing the level of uncertainty, the entire system is susceptible to extreme stresses that could propagate shocks throughout the entire network. Such risks highlight the importance of safety and comfort along each trip, such as providing seats for all, avoiding crowds in the vehicle, on stops, stations, and waiting areas, with contingency transport services in case of incidents.Meeting individual and collective mobility needs within a community is influenced by the existing and planned land use and depends on the available transport services. Furthermore, the enormous dispersion of individual limits to a free mobility related to a disability, older age or any temporary or occasional impairment or condition, accessible and inclusive transport services are required to fit the user’s mobility needs. The steps of the planned trip, like connections to other vehicle or network, could impose some difficulties that should be previewed, offering solutions to avoid exclusion. Finally, a barrier-free walking environment to reach or leave a transport network should complete the requests for the provision of transport services to accommodate everyone’s activity limits.The proposed Service Quality Assessment model is based on the quality loop involving the users’ feedback and the transport operators’ awareness of the planned and actual service level. Innovative technology supporting an Immersive Virtual Environment as a design, testing, and demonstration tool, will be described to identify new needs, design, test and to apply new solutions.
The Design Thinking Practice of Future Urban Public Transport Service under the Thinking of Double Diamond Model
Authors: Wang Yifei
Published: June 2023

In the post-epidemic and digital era, with the rapid development of autopilot technology and transformation processes of society, the project aims to study the service design strategy and specific scheme of the transport system in complex urban public environments for the future. Based on the divergent convergence and iterative characteristics of the double diamond model, the collaborative design of community residents and professional design based on research methods and design tools were connected to carry out design practice and envision future scenarios intertwined with physical and digital in the autopilot system. In this paper, the whole process of transport in the urban scene was investigated, the key pain points of users and corresponding design opportunities were sorted out, and the service system framework of future transport in urban settings in the future era was proposed. The key touch points of transport services for residents in urban scenes were explored to form integrated design interventions of convenient, considerate, constructive, and inclusive products and systems. The innovative solution with strong integration in this project is conducive to better grasping the product and service forms of transport at the grassroots level and improving users' positive feelings, sense of participation, and experience in the autopilot system in their daily life, thus improving the quality and availability of public transport services which have a positive impact on the efficiency and sustainability of urban areas.
Why the stability-flexibility-dilemma should be taken into consideration when studying pilots multitasking behaviour
Authors: Stasch Sophie-Marie , Mack Wolfgang
Published: June 2023

The ability to execute multiple flight tasks simultaneously is a basic requirement for safe aircraft operation. To the present time, there is no consensus about the degree to which simultaneous task execution is actually possible without performance decrements. The flexibility perspective on multitasking explains how cognitive control enables task sets to be flexibly activated and shielded from interference. However, cognitive control is subject to the stability-flexibility dilemma. This dilemma describes the conflicting demands on cognitive control that influence goal-directed behaviour in multitasking situations. On the one hand, cognitive stability has the advantage of minimizing task interference, while not facilitating flexible goal updating. On the other hand, cognitive flexibility allows for constant background monitoring and facilitates task switching. In addition, it has been demonstrated that overlearned action sequences reduce multitasking costs, but are also accompanied by mitigated behavioural flexibility. However, behavioural flexibility is particularly necessary in novel and complex flight scenarios to ensure a pilot’s rapid operational readiness. This issue raises two questions: How does the stability-flexibility-dilemma affect multitasking performance in flight environments? And which control mode is strategically beneficial in which flight scenarios? To answer these questions, the cognitive control mode of 34 subjects was experimentally manipulated in a multitasking flight environment. A gamification method shifted the participants control mode in a more stable and more flexible control mode respectively. Results show not only differences in the performance of the individual flight tasks, but also in the subjective workload and various eye tracking metrics. The latter could be taken into account by a cognitive assistance system to detect the control mode of pilots in real time. It enables appropriate assistance to be provided, taking into account the control mode and situational demands. Ultimately, this leads to the provision of situation-specific assistance with the potential to enhance the overall safety in the cockpit.
Human-Machine Interaction Challenges for Bridge Operations in Large Passenger Ships and Future Improvements from The Deck Officers' Perspective
Authors: Man Yemao , Brorsson Emmanuel , Bjorndal Petra
Published: June 2023

Technological bridge solutions have been implemented to improve safety and efficiency, but deck officers still face challenges in their daily use of these tools. Prior maritime human factors research has primarily focused on investigating issues such as workload, stress, teamwork, and situation awareness in ship operations, with limited attention given to the integration work, dynamic context, and factors on the system design level. Through interviews with maritime experts and field studies on two large Baltic passenger ships, this study examines the human-machine interaction challenges in today's bridge operations and identified areas for improvement. The results do not only explore the integration challenges imposed on the mariners, but also identify several contextual and system factors that contribute to these challenging bridge operations: dynamic situations and uncertainties, potentially conflicting goals, trust issues, lack of tool support and standardization. Suggestions for future improvements to bridge systems from the deck officers' perspective are also presented, with a focus on supporting proactivity, trust, context-awareness, and system integration. A few system design reflections were also made to fathom the challenges and inform potential future design directions. The study provides a thorough understanding of human-machine interaction challenges in bridge operations, which sets a foundation for future design and deployment of human-centered integrated bridge systems.
Mobile Game Design and Ergonomics: a necessary combination
Authors: Machado De Andrade Wiliam
Published: June 2023

Games for mobile phones constitute a fast-growing industry, with technologies and business models that explore their portability and facilitated access. The human factors on mobile playing did not follow such a development. With devices using touchscreens to control the game, usability ignored the ergonomics of holding and interacting with handheld narratives in opposition to video game console controllers. This article studies mobile gaming ergonomics to understand how playing with a handheld device changes body alignment, pondering whether game design can lead to or avoid postural injuries in the long term. While console and desktop computer gaming are likely to occur in controlled settings, mobile gaming can happen in varied places and situations. Some games demand players to hold their devices with a single hand, making it difficult to distribute the weight and adjust the grip. Playing while standing up may cause arm and wrist fatigue while gamers try to achieve better visualization. In addition, small onscreen content can also prompt neck stretching, altering the body's axis. Even though the current literature reveals some concerns regarding video games and ergonomics, they commonly focus on the players but not on the game content. Thinking about the latter, is it possible to plan the game to reduce the risk of injuries when playing with a handheld device? As a first step toward a potential answer, the research investigates (1) the body risks when holding a smartphone; and (2) some distinct game features from other mobile operations that can aggravate potential injuries. The conclusions suggest some approaches to game design to reduce the risks in the long term, also attempting to make part of further discussions on ergonomics to make mobile gaming safer for the body.
Game-based Plant Science Popularization Mobile Application for Contemporary Young People
Authors: Li Yuqi , Wang Sijia , Zhang Hongyu
Published: June 2023

Nature is the basic condition for human survival and development. The nature-deficit disorder is a phenomenon put forward by American writer Richard Louv, that is, the complete separation of modern urban children from nature in the 21st century. Some experts explain that this desire and ignorance of nature is due to a lack of time to go outdoors, especially in the countryside. In real life, the population of "nature-deficit disorder" has expanded from children to adults. In order to let young people go into nature and understand the thousands of plants in nature, our team wants to design an application to popularize plants through a game-based live experience, so that users can learn more plant knowledge in fun. This design adopts the methods of the questionnaire survey, user interview, and literature retrieval to deeply discover the contemporary young people's understanding of plants, the development status of game-based science popularization apps at home and abroad, and the expected functions of users, to determine the information construction, visual image and interactive experience of the APP. Our team uses Rhino, Cinema 4D, Blender, Unity, Unreal and other software, combined with ergonomics to achieve scene modeling and rendering, to create a more realistic AR experience. The APP can guide users to enter the virtual map, take photos and punch cards through AR switching angles, and randomly obtain passes to unlock other maps. At the same time, users can click to view specific plant data, unlock the plant by completing key tasks such as roots, stems, and leaves, and bring it into the backpack for creation; the app can also game the handicraft which uses plants as raw materials, and guide users to create their own unique imprint. After the usability test, the respondents all believed that this APP could produce a better effect of plant science popularization in the game experience.

Published: June 2023

This article aims to contribute to a better understanding of the role of open science and its impact on knowledge management in the open innovation environment. The main premise of open innovation in the Europe Commission’s vision for Europe is to open the innovation process to all stakeholders from academia, business, government, and society. Owing to that, knowledge may create investment opportunities for innovative products and services as well as competitiveness in new markets. Open science is a relatively new approach to the scientific process, which is based on collaboration and advanced ways of spreading knowledge by using digital technologies and new tools. Open Science affects the entire process expanding its boundaries and permitting knowledge to be widely and quickly shared as well as easily updated. The idea is to make a profound change in science and research - moving from the traditional and well-established practice of disseminating research results in academic journals, seminars, and conferences to open sharing of the acquired knowledge and bringing it closer to the earlier stages of the innovation process. Open Science also involves a shift towards more open knowledge management in the open innovation environment. To ensure that knowledge management should be based on the principles of open science. This requires considerations of such critical factors as relevance, authenticity, and security of data sources while using the readily available results of open science. This article analyses the proposed open knowledge management framework reflecting on the impact of open sciences principles.

Additive manufacturing (AM) positions as a system in systems (SoS) to which ecosystem is often difficult to assess in cost curve in bulk, peculiarly in challenging mediums. This paper presents an AM-related solution in the aerospace domain of recent sources forming a review of future space manufacturing. The paper presents an example of a sustainable circular economy based on AM through systematic product lifecycle management (PLM) design domain implementation methodology. Developing an agile business sustainable human system integration (HSI) model, human factors, and ergonomics (HFEs) based on the surrounding medium and structure with fine-designed system fidelity require reciprocal signal communication. A turbulent market environment shaped future communication space between domains of human systems stakeholders sets challenges on communication. HSI applies the ecosystem design to comply with various sectors' companies' stakeholders. The HSI design ensures that the design can simplify by the systems engineering method utilizing axiomatic design (AD). The mathematical AD analysis results as a design matrix (DM) that qualitatively represents the internal design parameters as SoS for energy capture, reuse with dynamic motion innovation on thermal power propulsion, and THz-controlled semi-autonomous operations. Future studies in virtualizing models in the metaverse are proposed for the design solution of the system.

Bruce Gilden Fotoğrafında Grotesk ve Karnavalesk Unsurlar: Bakhtinci Bir Yaklaşım
Authors: ŞEN Savaş Onur
Published: June 2023

Mikhail Bakhtin’in karnaval ve grotesk üzerine düşünceleri onun halk kültürüne ve özellikle de bu kültür içerisindeki gülme unsuruna gösterdiği önemden kaynaklanmaktadır. Kompleks bir yapı barındıran karnaval gülüşü, belirli bir dönem için hiyerarşilerin yerle bir edildiği halk için gülmenin oluşturduğu ikinci bir dünya anlamına gelir. Sıradan bir eğlence ya da kutlamanın çok ötesinde önem taşıyan bu yeni düzlem toplumsal açıdan çok farklı yansımaları da içerisinde barındırır. Bakhtin açısından karnaval bu noktada, bütün hiyerarşilerin yerle bir edildiği ikinci bir dünya olarak karşımıza çıkmakta, grotesk gerçeklik ise bu yerle bir edilişin temsillerini belirleyen imgesel dokuyu oluşturmaktadır. Grotesk, karnavalın imgesel düzeydeki temsili ya da yansıması olarak karşımıza çıkarken, karnavalla ilişki içerisinde anlaşılabilir. Bakhtin’in bu noktada groteske ilişkin temel kriteri onun tamamlanmamış devinim ve dönüşüm halinde olmasıdır. Oluş halindeki grotesk beden bir topografya olarak tıpkı karnavalda olduğu gibi alt üst edilmiştir. Bu çalışmada Bruce Gilden’ın fotoğrafları Bakhtinci anlamda karnaval ve grotesk kavramları çerçevesinde incelenecektir. Gilden’ın fotoğraf üretim stratejisinin, çalışmak için seçtiği konuların ve üslubunun onun fotoğrafında karnavalesk ve grotesk unsurların güçlenmesine yaptığı katkı ve sonuçları ele alınacaktır.

TWITTER SENTIMENT ANALYSIS
Authors: Mishra Jayant
Published: June 2023

Sentiment analysis is a popular research field that aims to extract opinions, attitudes, and emotions from social media platforms like Twitter. Traditionally, sentiment analysis has focused on analyzing textual data. Twitter, being a well-known microblogging platform where users post updates in the form of tweets, is often used as a data source for sentiment analysis studies. In this particular paper, the authors utilize a publicly available labeled dataset from Kaggle. They also propose a set of preprocessing steps to enhance the manageability of tweets for natural language processing techniques. Since the dataset consists of pairs of tweets and their corresponding sentiment labels, supervised machine learning is employed. The authors propose sentiment analysis models based on naive Bayes, logistic regression, and support vector machine algorithms with the objective of achieving more effective sentiment analysis. In Twitter sentiment analysis, tweets are typically categorized into positive or negative sentiment. Machine learning classifiers can be utilized for this purpose. These classifiers can be valuable for various entities such as businesses, political parties, and analysts, as they can evaluate the sentiments expressed towards them. By appropriately training the machine learning models with labeled data, tweets can be accurately classified without the need for a predefined word database. Consequently, machine learning techniques offer a superior and faster approach to performing sentiment analysis.

The Contexts of Indigenous Music Activity in the Kimberley: Pedagogic Models for Aboriginal Music
Authors: Dunbar-Hall Peter
Published: June 2023

In response to documented problems in the teaching of Australian Indigenous music in schools, this paper proposes the use of the contexts of music as the bases of pedagogic models. In relation to Indigenous music activity in the Kimberley region of north-west Australia, four contexts are explained and their potential to provide ways of studying Indigenous music is explored:

Kimberley Indigenous music in relation to national Aboriginal music

music and history

music and place

music and politics

While these contexts provide relatively simple ways of structuring pedagogies for Indigenous music, their potential to represent the symbolic levels of music as expression of cultural concerns bay be their real significance in the attempt to utilise Indigenous music in music education.

The nature of the relationship between people, land and ancestors in Australia Aboriginal societies has generated ongoing anthropological debate. Since the inception of anthropological studies of Aboriginal religion, the idea of totemism has been used to elucidate the spiritual and physical relationship between these elements. The paper begins with a re-evaluation of the human-ancestor-land complex, focusing particular on theorists of Australian totemism such as Stanner (1966), concerniing Aboriginal religion, and Munn's (1973) seminal explanation of transformations of objects into subjects and subjects into objects in Walbiri ideology.

The Influence of Operational Flow Analysis Reports and Investment Cash Flows on the Stock Prices of Electronics Companies on the Indonesia Stock Exchange (IDX), 2018 - 2021.
Authors: Gulo Hevin Rivaldo , Ginting Kristi Endah Ndilose
Published: June 2023

Indonesia's economic development has exhibited consistent growth over recent years, as demonstrated by the increasing number of state-owned and foreign companies establishing operations within the country. This proliferation has intensified business competition, compelling companies to continuously strategize to maintain competitiveness and aspire to be market leaders within their sectors. A critical component of business operations is cash flow management, with operating cash flow reports playing a pivotal role. These reports, directly linked to the activities involved in determining a company's net income for a specific period, reflect the company's revenue from transactions impacting profit or loss, offering an overview of cash flow from operational and investment activities. This paper examines two companies listed on the Indonesia Stock Exchange (IDX) as case studies. Company ATIC, in 2020-2021, experienced a 16.22% increase in cash flow from operating activities and a 15.63% rise in earnings per share. In contrast, its share price fell by 1.88%, suggesting potential challenges. Likewise, Company PTSN, in 2019-2020, observed a significant reduction in cash flow from investing activities by 114.86%, even as its share price rose by 39.71%, again indicating potential difficulties. These cases illustrate the profound influence of operational and investment cash flows on stock prices

Electrocatalytically active nanocomposites play a vital role in energy generation, conversion, and storage technologies. Transition metal-based catalysts such as nickel and iron and their pnictide (phosphide), and chalcogenide (selenide) compounds exhibit good activity for hydrogen evolution reaction (HER) in the alkaline environment. In this study, transition metals-based catalysts (Ni-P-Se, Fe-P-Se, and Ni-Fe-P-Se) solutions were prepared using a simple one-pot method. Prepared solutions were deposited on Ni foam, and different characterization techniques were used to determine the composition, structure, and morphology of as-prepared catalysts. Furthermore, it was found that Ni-Fe-P-Se as a cathode material showed better HER performance compared to other investigated materials with the overpotential value of 316 mV at 10 mA cm-2 current density and 89 mV dec-1 Tafel slope value. The stability tests of the as-prepared catalyst confirmed that the synergistic effect between various elements enhances the electrocatalytic performance for up to 24 hours, providing a fair, stable nature of Ni-Fe-P-Se based sample.

Es indiscutible el valor cultural y ancestral adquirido y depositado en las Comunidades Andino- Amazónicas, sobre el correcto uso de las plantas medicinales; el mismo que lamentablemente hoy en día corre el riesgo de desaparecer debido a la globalización. En tal sentido, la investigación buscó determinar las enfermedades más frecuentes tratadas con plantas medicinales por el poblador de Huamachuco, Sánchez Carrión, La Libertad- Perú. Para lo cual se realizaron un total de 96 entrevistas, utilizando el método de selección de la muestra aleatoria, teniendo en cuenta que cumplan en todo momento los criterios de inclusión. Asimismo, se eligió la cantidad de población a entrevistar, y obtener: la cantidad (%) de los habitantes que utiliza plantas medicinales, así como los tipos de enfermedades y/o padecimientos que agobian a la población. En los resultados obtenidos se halló que el 90% de la población de Huamachuco usan plantas medicinales y el 10% no hace uso de las mismas. Se concluye que las enfermedades más frecuentes tratadas con plantas medicinales, son las relacionadas a los sistemas digestivo y gastrointestinal, sistema respiratorio y sistema urinario.
Síntesis y extracción de sustancias húmicas a partir de residuos orgánicos compostados provenientes de la industria alimentaria Lima, Perú 2022

En el Perú el volumen de residuos orgánicos alimentarios está entre el 47% y el 50% del total de residuos sólidos proveniente de la industria alimentaria y otros eslabones de la cadena, siendo las causas de este problema el inadecuado manejo integral y su disposición final. En ese sentido objetivo fue evaluar la síntesis y extracción de sustancias húmicos del compost de residuos orgánicos señalados. La metodología consistió en la compostación vertical (120 días) de 4 pilas más microorganismos activados, el agua en la remoción y ventilación; luego siguió la humificación por 60 días más. En los resultados finales las cuatro (4) pilas de compostación tuvieron valores de síntesis en ácidos húmicos (%) 3.44±0.5; 3.30±0.5; 3.56±0.5; 2.54±0.5; y en ácidos fúlvicos: (%) 1.31±0.3; 1.46±0.3; 1.28±0.3; 0.83±0.3; con rendimientos de compost por encima del 35% y una humedad sobre el 49%. Los valores del pH están 5 y 7. Con respecto a la capacidad de intercambio catiónico más baja y la más alta fue 51.3 meq/100g. Finalmente el compost obtenido proporcionó un buen índice de germinación en el maíz.

Background: Cardiovascular diseases are a leading cause of death. The growing problem of lipid disorders, hypertension, and overweight among young people may lead to dangerous cardiovascular disease-related consequences. Aim of the study: Assess the prevalence of selected cardiovascular disease risk factors among medical students. Material and methods: The study included 201 medical students from the Faculty of Medicine and Health Sciences of the University of Technology and Humanities (UTH) in Radom. A diagnostic proprietary survey method collected heart rate, blood pressure, and body composition data using a TANITA device. The results were analyzed by analysis of variance (ANOVA) and the Shapiro-Wilk test using R statistical software, while the post hoc analysis employed t-tests with Bonferonis correction. Results: Heart rate and blood pressure were within normal limits in most subjects. Low physical activity and increased fat mass were confirmed in the students with a higher metabolic than metric age. Furthermore, nursing students had higher mean fat mass and lower mean basal metabolism values than students of other majors, especially medicine. Conclusions: The health-promoting aspects of behaviors favoring a healthy body weight and sleep hygiene, as well as not smoking and having low alcohol consumption, were observed in the study group. However, some lifestyle elements, including eating habits, must be modified.
