In the rapidly evolving landscape of the Internet of Things (IoT), effective communication and security are paramount. Blockchain technology offers a transformative solution by providing a decentralized, transparent, and immutable ledger for managing and securing IoT interactions. By leveraging blockchain, IoT systems can enhance data integrity, improve trustworthiness, and streamline communication processes. This paper investigates the integration of blockchain technology within the SYMHIOT framework, focusing on the performance evaluation of various scenarios using a Hidden Markov Model (HMM) to manage IoT networks. The study analyzes key metrics such as transaction success rate, blockchain latency, energy consumption, packet delivery ratio (PDR), and throughput across multiple scenarios and time intervals. The results demonstrate that State 1 consistently yields optimal performance, with an average transaction success rate of 94.0%, blockchain latency as low as 115 ms, and energy consumption of 0.42 J. In contrast, State 3 exhibited the most challenging conditions, with a transaction success rate dropping to 85.3%, latency increasing to 140 ms, and energy consumption rising to 0.52 J. The highest packet delivery ratio of 99.0% and throughput of 260 kbps were also observed in State 1. Scenario 4, representing an optimized system configuration, achieved the best overall performance with minimal network delay (9.7 ms) and the lowest blockchain overhead (12.9%). These findings underscore the potential of leveraging blockchain in IoT environments, offering enhanced security, reduced latency, and improved resource efficiency, making it a robust solution for dynamic and resourceconstrained IoT networks.

Robot path planning and tracking involve two critical aspects of autonomous navigation systems: determining an optimal route for the robot to follow and ensuring that it accurately adheres to this path in real-time. Path planning focuses on generating a feasible and efficient trajectory from a starting point to a destination while considering obstacles, dynamic environments, and constraints. This paper investigates the effectiveness of the Flower Pollination Search Optimization (FPSO) algorithm for robot path planning and compares its performance with traditional algorithms such as A* Algorithm, Dijkstra, and Rapidlyexploring Random Tree (RRT). The FPSO algorithm was evaluated across three distinct scenarios, demonstrating superior performance in terms of path length, computation time, and path smoothness. In Scenario 1, FPSO achieved an optimized path length of 10.5 meters with a computation time of 3.2 seconds, a path smoothness score of 8.9, and a path efficiency of 95%. In Scenario 2, FPSO resulted in a path length of 12.3 meters and a computation time of 3.5 seconds, with a smoothness score of 8.7 and an efficiency of 93%. Scenario 3 showed FPSO's best performance, with a path length of 9.8 meters, computation time of 3.0 seconds, a smoothness score of 9.0, and a path efficiency of 96%. Comparatively, the A* Algorithm, Dijkstra, and RRT exhibited longer path lengths and higher computation times, with lower smoothness scores and efficiencies.
Trends of Egyptian Youth Towards Freedom of Expression on the Internet: A Cultural Analysis (Arabic)
Authors: Salaheddin Ali Khaled
Published: September 2024

According to statistics released in December 2017, the number of web users in Egypt are about 49.23 million. This represents about 49.5% of the population estimated at 99.4 million. The number of users subscribed on the Facebook network is about 35 million. Youth represent the largest segment of web users, including applications and multimedia. This study examines Egyptian youth trends and attitudes towards freedom of expression across multiple platforms, through objective and codified mechanisms, that lead to an integrated understanding of the role of the internet in promoting freedom of expression from the end user’s perspective. Since the study is concerned with the effects of cultural characteristics of Egyptian society in determining the users’ assessment of the web, it is based on the Cultural Analysis Model, which takes into account the general features that support or impede these characteristics in the youth’s digital freedom of expression in the web’s virtual environment. The study uses the survey methodology, in both descriptive and analytical terms, when relying on a sample of the youth population, he used the Available Sample method, since it is the most widely used sample in the field of surveys conducted on relatively homogeneous societies, as is the case in the youth community, which has many common characteristics, given the similarity of age groups and the shared social and cultural beliefs. The study was conducted on a sample of 400 respondents in the greater Cairo region, including cities of Qalioubia, Cairo, and Giza, since it is the most densely populated region among the seven regions of Egypt. It also includes several subsets of Egyptian society, both economically and culturally. The results of the study indicate that the web does not contribute to social consensus, because it is operated horizontally, therefore its users impose their priorities on its different applications, in contrast to the traditional means of agenda setting.
Mohammed Assaf’s victory five years on: Arab Idol and the Zionist colonization of Palestine
Authors: Brehony Louis
Published: September 2024

This essay, based on the author’s fieldwork on Palestinian music and oral history, examines the position of singer and Arab Idol winner Mohammed Assaf in relation to the contemporary Palestinian struggle and the wider play of power in the Arab world. The issues discussed gravitate towards three main themes: the relationships between musicians and a liberation movement facing a crisis of leadership as Israel builds its repressive armoury. Second, the Arab Idol phenomenon as part of the growing interventionism of the Saudi ruling class in regional societies. And relatedly, the growing fissures between a Palestinian comprador bourgeoisie and the grassroots movement of the oppressed. More generally, this essay looks at the space for radical nationalist music and argues that, as in the crucial struggles for Palestine over the course of the last century, history and music will continue to be written on the streets.

Published: September 2024

Despite the importance of volunteerism for sustainable development objectives and youth investment of time in such useful volunteer work, the practice of voluntary social work differs from one context to another, as does its efficiency and effectiveness. This study examines the role of social networks in promoting volunteer work among Saudi university youth in times of crisis and supporting their social capital values. The study is based on a sample survey methodology, this approach belongs to the category of explanatory or analytical surveys that goes beyond the description of characteristics to an attempt to explain the behavior and its relation to the characteristics of the phenomenon under study. This methodology is designed to describe, analyze and interpret the role of social networks in supporting and promoting volunteer work among university youth in times of crisis and disaster in the Kingdom. The study was conducted among 500 youth. both male and female, at Saudi universities (King Abdul Aziz in Jeddah, King Khalid in Abha and Naif University for Security Sciences in Riyadh). The selection of the sample took into account the specific controls of being between the ages of 18-35 years, from both genders, and to be users of the social networks participating in volunteer work. The results of the study showed that the social network platform Twitter, took the lead in terms of exposure in times of crisis and disaster, and that the university youth in the Kingdom have positive attitudes toward volunteering. The results also indicate the high rate of university students' use of social networking sites in the field of volunteering, and their support to it as a source of information and exchange of opinions, comments, photos, and videos among users relating to the importance of volunteering in times of crisis.

Este trabalho de revisão analisa o impacto da dobutamina na estabilização hemodinâmica de pacientes com insuficiência cardíaca descompensada. A insuficiência cardíaca descompensada, uma condição crítica caracterizada pela incapacidade do coração em manter um débito cardíaco adequado, frequentemente exige intervenções rápidas e eficazes. A dobutamina, um inotrópico positivo, é amplamente utilizada para melhorar o débito cardíaco e a perfusão tecidual em pacientes com fração de ejeção reduzida. A revisão se baseia em uma análise crítica de estudos recentes que investigam a eficácia da dobutamina, comparando seus efeitos com outros agentes terapêuticos. Embora a dobutamina seja eficaz a curto prazo na estabilização hemodinâmica, seu uso prolongado pode estar associado a riscos e efeitos adversos, como taquifilaxia e arritmias. A revisão também discute a importância de adaptar o tratamento às necessidades individuais dos pacientes e de considerar as alternativas disponíveis. Os resultados destacam a necessidade de uma abordagem equilibrada para o uso da dobutamina, enfatizando a importância de monitoramento contínuo e avaliações clínicas detalhadas.
Focusing Forward: How to Traverse New Leadership While Emphasizing Continuity
Authors: Westover Jonathan
Published: September 2024

Abstract: This article provides best practices for navigating leadership transitions when new senior executives are hired, drawing on research regarding organizational change, leadership, and human psychology to understand common reactions to change and offer evidence-based strategies. It recommends proactively reducing uncertainty through over-communicating regularly with varied forums, tailoring updates for different stakeholder groups, highlighting complementary strengths rather than differences in strategy or priorities, and addressing core human needs for security and belonging. A case study demonstrates these concepts as a director successfully handled new C-suite hires by holding weekly Q&As, discussing concerns privately with the new CTO, leveraging advisory networks for intelligence on new leaders’ focus, reassuring teams existing work remained strategically important, and emphasizing synergies between current and new areas of focus. Key implications explain how framing changes as natural evolution rather than disruption builds buy-in, and that with clarity of purpose and commitment to organizational mission, leaders can guide teams productively through transitions by managing both information and the human side of change.

Published: September 2024

The aim of this research is to evaluate Curriculum Effectiveness: Understanding the extent to which a competency-based curriculum can improve the quality of education by measuring student learning outcomes, level of mastery of material, and students' ability to apply the knowledge and skills they learn. This research uses qualitative/quantitative methods with a descriptive approach. Some of the instruments used in this research are student portfolios, practical exams, formative assessments. The researcher's data collection techniques used interviews, questionnaires, classroom observations, classroom observations, document analysis, exams and assessments, focus group discussions, and reflective notes. This research shows that the implementation of Competency-Based Curriculum (KBK) in the context of school education requires the active involvement of teachers in preparing more contextual learning that is oriented towards skills development. Students are expected to become successful, honest, disciplined, and responsible individuals. However, the quality of education in Indonesia still requires many improvements, including the implementation of appropriate policies as an alternative solution to educational problems. Relevant KBK programs with initiatives for training education personnel include participation in various places, development of family planning organizations, and utilizing the education process to address educational gaps. The importance of administrative support, resource availability, and continuous evaluation and assessment are key to the successful implementation of KBK. Parental and community involvement are also crucial in supporting the implementation of KBK, which ultimately positively impacts the quality of education, student motivation, and alignment with local needs.

Perceived Muscle Soreness In Recreational Female Distance Runners
Authors: Burnett Dave , Burns Steve , Smith Kevin
Published: September 2024

The purpose of this study was to determine if rating of perceived exertion correlated with perceived muscle soreness during delayed onset muscle soreness (DOMS) in female runners. This study examined the pre and post running economy measures and perceived muscle soreness before and after a 30 minute downhill run (DHR) at - 15% grade and 70% of the subjects predetermined maximum oxygen uptake (VO2 peak). Methods: Six female recreational runners (mean age = 24.5) performed level running at 65%, 75%, and 85% of their VO2 peak prior to DHR (baseline economy runs), as well as, immediately following and 4 successive days after the DHR. Results: Subjective response related to perceived muscle soreness increased significantly from a mean of 2 (pre DHR) to 62 (2 days post DHR) on a scale of 1-100. Creatine kinase levels and oxygen consumption increased post DHR compared to pre DHR. Rating of perceived exertion did not change between the economy runs performed prior to or at any point after the DHR. Conclusion: Perceived muscle soreness is a better tool than the RPE scale to monitor exercise intensity for recreational female runners during periods of DOMS and running economy is adversely affected by DOMS.
Multiple Models Can Concurrently Explain Fatigue During Human Performance
Authors: Laurent Matthew , Green Matt
Published: September 2024

One of the most commonly and thoroughly studied paradigms of human performance is fatigue. However, despite volumes of research there remains considerable controversy among scientists regarding definitive conclusions about the specific mechanism(s) contributing to fatigue. Within the literature there are three primary yet distinctly different governing ideas of fatigue; the traditionally referenced central model and peripheral model as well as the emerging central governor model (CGM). The CGM has recently been advocated by a limited number of researchers and is suggestive of a more integrative model of fatigue when compared the traditional peripheral and central models. However, more work is needed to determine the specific and perhaps synergistic roles of each paradigm during exercise or sport activity. This article contains three components; (1) a brief overview of the problems associated with defining fatigue, (2) a description of the models governing interpretation of fatigue and, (3) a presentation of multiple interpretations of selected data to demonstrate that some results can be reasonably explained using multiple models of fatigue, often concurrently. The purposes of this paper are to reveal that a) perhaps it is not the results that suggest a certain paradigm of regulation, yet that it may be a product of an a priori definition that is being employed and b) an integrative model of central and peripheral fatigue may present a plausible explanation for fatigue vs. adherence to the notion that each paradigm is mutually exclusive.

Parameters of Walking and Jogging in Healthy Young Adults
Authors: Barreira Tiago , Rowe David , Kang Minsoo
Published: September 2024

The purposes of this study were to a) investigate the average heart rate (HR), speed, stride length, and stride rate during moderate intensity walking and jogging in healthy young adults, b) cross validate the walking stride length calculation based on 42% of height and c) provide reliability information for measurement of walking and jogging steps, speed, stride length, and stride rate. Participants (N=130) wore two Yamax SW-200 pedometers and a Polar A-1 HR monitor while performing walking and jogging trials. The correlation between estimated (0.71 ± 0.04 m·stride-1) and actual stride length (0.78 ± 0.05 m·stride-1) was moderate (r = .46). However, a significant difference was observed between the two measurements (t(115) = -14.24, p < .001). The reliability results for speed, stride length, and stride rate showed that two or fewer trials were enough to achieve reliable estimates. In conclusion, when instructed to walk at a moderate pace, healthy young adults tend to walk at an average pace that is greater than that recommended for meeting current public health recommendations (80 m·min-1). Similarly, when instructed to jog at a comfortable pace, healthy young adults tend to jog at a speed greater than that corresponding to vigorous intensity physical activity (134 m·min-1). The results of the reliability analysis indicate that in healthy young adults, to measure typical walking and jogging patterns using a pedometer, only two trials for walking and one trial for jogging are necessary to achieve reliable estimates. Stride rate calculations requires the combination of two trials and one pedometer for both walking and jogging.
Association of Body Surface Area and Body Composition with Heart Structural Characteristics of Female Swimmers
Authors: Saraf Bahreh , Nikbakht Hojat , Azarbayjani Mohammad
Published: September 2024

In healthy nonathletic populations, some left ventricle (LV) parameters such as LV mass (LVM) and LV end diastolic dimension (LVEDD) can be predicted by some of body size parameters such as body surface area (BSA), fat-free mass (FFM), and height (H). These body size parameters use to remove covariate influence of body size from cardiac dimension variables and allow comparisons to be made between individuals and groups of different body size. Endurance exercise has been associated with changes in LV size and body composition of athletes. The aim of this study was to evaluate in 30 trained female swimmers (age range 12-17 years) possible correlations between BSA, FFM, fat mass (FM) determined by bioelectrical impedance analyzer(BIA); and a range of cardiac dimensions derived by echocardiography. Univariate correlations were studied between left ventricular and body size variables. Stepwise multiple linear regression was performed to determine the best determinants of LV variables. LVM and LVEDD had a significant relation with FFM and BSA (p<0.001), (p<0.05) respectively. Left ventricle posterior wall thickness (PWT) had a significant relation with BSA (p<0.001) and FFM (p<0.005). No relation was found between heart’s structural variable (LVM, LVEDD, LVESD and PWT) and FM. Using a multivariate regression analysis, FFM was the only independent predictor of both LVM (R2=0.541, p<0.001) and LVEDD (R2=0.189, P<0.05). These results suggest that Correction of LVM and LVEDD by FFM in athletes may be more appropriate than other measures of body size for indexing absolute amounts of LV dimension. Yet further researches in other athletes are required to confirm these findings.
Independent Multiple Correlates of Post-Exercise Systolic Blood Pressure Recovery in Healthy Adults
Authors: Dimkpa Uchechukwu , Ugwu Andrew
Published: September 2024

The aim of the present study was to evaluate the independent relationships of systolic blood pressure recovery (SBPR) with age, sex, body mass index (BMI), waist circumference (WC), resting heart rate (HR), physical activity, and cigarette smoking in healthy adults. Subjects performed cycle ergometer exercise at progressive incremental workloads until subjects reached 80% of their age-predicted maximum HR. Blood pressure (BP) was measured before exercise (after 10 and 15 minutes of rest), during exercise (at 2-minute intervals), immediately after exercise (within the first minute) and subsequently at 2-minute intervals until recovery to baseline. The ratio of third-minute SBP relative to first-minute post-exercise SBP was used as the SBPR variable. Our results indicated independent correlations (p<0.05) between SBPR and age, resting HR, physical activity and cigarette smoking (r =0.473; 0.192; -0.262; 0.102 respectively in males and r =0.113; 0.315; -0.637; 0.104 respectively in females). BMI associated positively (r =0.106; p<0.01) with SBPR in males but not in females (r =0.092), while WC was predictive of SBPR in females (r =0.212; p<0.01) but not in males (r =0.005). Age in men and physical activity in females were the strongest predictors of SBPR. The present findings in which SBPR is associated with risk factors of cardiovascular abnormalities strengthen the previously reported significance of SBPR after exercise test as a prognostic tool for the evaluation of cardiovascular abnormalities. Additionally, it may help clinicians to define and interpret the mechanisms behind changes in postexercise SBP responses in adults in future investigations.

A person’s subjective experience to their first exercise session is likely to influence their long-term adherence to regular exercise. The aim of the current pilot study therefore is to quantify the subjective exercise experience of previously sedentary Vietnam War Veterans undertaking an initial bout of one of three different exercise interventions. Thirty-two Vietnam Veterans presenting with one or more chronic diseases/conditions participated in one of three acute exercise bouts: 1) lower-body vibration, upper-body resistance and stretching (WBVT); 2) lower-body vibration, upper-body resistance, aerobic exercise and stretching (WBVT+CV); and 3) full-body resistance, aerobic exercise and stretching (R+CV). Pre and post acute exercise measures of positive well being, psychological distress and fatigue were assessed with the Subjective Exercise Experiences Scale (SEES). A 3(conditions) x 2(time) repeated measures ANOVA with post-hoc Tukey HSD was used to identify any significant differences in SEES between exercise groups and pre and post-exercise. All interventions increased positive well being, with WBVT and R+CV reporting improvements across all areas of the SEES. The WBVT+CV group reported slightly increased psychological distress and the greatest increase in fatigue. An acute bout of exercise increases positive well-being in previously sedentary War Veterans however a longer-duration exercise bout containing multiple exercise modes may be too demanding for this population. Exercise professionals should consider commencing with a simple program to minimise psychological distress and fatigue as this may negatively impact on exercise adherence.

The purpose of this study was to pilot a 5-week community-based intervention on improving measures of health-related fitness in overweight children. Data were obtained from 8 overweight and obese 8- to 14-year-old children. Measurements included muscular fitness (curl-ups and modified pull-ups), aerobic capacity (20 meter progressive aerobic cardiovascular endurance run [PACER] test), body composition (tricep and calf skinfolds), body mass index (BMI), and flexibility (back saver sit-and-reach). A significant reduction in BMI was observed at post-test compared to baseline (p = .03). There was a significant decrease in body fat at post-test for boys (p = .013).

The present study was taken up to monitor the training load and the impact of training load to the hormone concentrations such as testosterone, cortisol and T/C (Testosterone/Cortisol) ratio during the three phases of training viz preparatory phase, pre-competitive phase and competitive phase in Indian male swimmers. Blood samples were collected at the completion of each phase and the hormone concentrations were quantified. Our results reveal that the testosterone and T/C ratio significantly decreases whereas cortisol increases in the subsequent periodised cycle and concludes that the hormone concentration changes with the intensity and duration of exercise i.e. when the intensity and duration of exercise is increased, the testosterone level decreases, cortisol level increases and T/C ratio decreases. This study shows a clear picture of performance enhancement with lowest mean cortisol level, high testosterone and T/C ratio level. Hence, monitoring of these hormones is essential to avoid overtraining and to enhance the performance of the swimmers.
Evaluation of Metabolic Stress between Jumping at Different Cadences on the Digi-Jump Machine
Authors: Navalta James , Callahan Zachary
Published: September 2024

The American College of Sports Medicine (ACSM) recommends that healthy adults achieve a minimum of thirty minutes of moderate intensity aerobic exercise five days per week. While cycling, walking, and jogging are commonly observed methods of achieving these recommendations, another option may be repetitive jumping. The purpose of this study was to examine the metabolic responses between repetitive jumping at a cadence of 120 jumps per minute (JPMs) vs. 100 JPMs when utilizing the Digi-Jump machine. Twenty-eight subjects completed two jumping trials, one at 120 JPMs and one at 100 JPMs. Subjects jumped until volitional exhaustion, or for a maximum of fifteen minutes. Oxygen uptake (VO2), heart rate (HR), respiratory exchange ratio (RER), and rating of perceived exertion (RPE) were assessed each minute of each exercise trial. RPE was differentiated, in that subjects reported perceived exertion of their total body, their upper-leg, and their lower leg. Results of this study indicated that there was no significant difference between the two trials for VO2, HR, or total body RPE. Differences were reported between trials for peak and average RER, with the 120 JPM trial eliciting a lower RER for both (peak: 1.08 + .087 vs. 1.17 + .1 p=.000; average: .99 + .076 vs. 1.04 + .098 p=.002), peak upper leg RPE (120: 15.29 + 3.89 vs. 100: 16.75 + 2.52 p=.022), and average lower leg RPE (120: 15.04 + 2.55 vs. 100: 13.94 + 2.02 p=.019). Also, there was a significant difference in exercise duration between the trials, with subjects able to exercise longer during the 120 JPM trial (12.4 + 3.42 mins vs. 9.68 + 4.31 mins p=.000). These data indicate that while the physiological stress may not be different between the two trials as indicated by VO2 and HR, the 120 JPM trial appears less strenuous as evidenced by RER values and by subjects’ ability to exercise longer at that cadence.
Leveraging Online Learning Resources to Teach Core Research Skills to Undergraduates at a Diverse Research University

Today’s students have unique learning needs and lack knowledge of core research skills. In this program report, we describe an online approach that we developed to teach core research skills to freshman and sophomore undergraduates. Specifically, we used two undergraduate kinesiology (KIN) courses designed to target students throughout campus (KIN1304: Public Health Issues in Physical Activity and Obesity) and specifically kinesiology majors (KIN1252: Foundations of Kinesiology). Our program was developed and validated at the 2nd largest ethnically diverse research university in the United States, thus we believe that it would be effective in a variety of student populations.
"¿Qué hacemos con estos manes?" Discurso de jóvenes en Medellín sobre corrupción y democracia
Authors: Jaramillo Escobar Lukas
Published: September 2024

The disaffection, the impotence and the mistrust of the youth in Colombian institutions and democracy in Medellin are interrelated with the comprehension, experience and observation of corruption. These relationships have a symbolic content that refers to the legitimacy of the very institutions that are observed. Additionally, the impotence not only has to do with the observation of the ever growing influence of corruption within the justice system, control institutions, but also the prevalence of violence as a resource and homicide as a direct consequence of speaking up and reporting corruption. Even though a sort of pragmatic pessimism is present from as early as fifteen years old many proposals are made and alternatives are built, primarily utilizing concepts such as democracy of proximity and creativity from the everyday environment.
Sobre la transformación del control fiscal
Authors: Erazo Montenegro Alma Carmenza
Published: September 2024

This experience has many nuances. On the one hand, personally it was a life decision. At that time he was part of the human team of the Comptroller General of the Republic, he had traveled a long path of learning about fiscal control, being part of the entity that defines the guidelines for the development of this constitutional function. At that time the contest to be the Valley's comptroller was opened and I decided to participate; I risked the comfort of the position I held, I trusted my abilities and thank God I was selected. This was another great opportunity that life gave me to test my ability and put into practice what I had learned. I experienced a similar situation later, when I competed to be comptroller of Santiago de Cali.
¿Los mecanismos de control fiscal son eficaces en la lucha contra la corrupción?
Authors: Quintero Navas Gustavo
Published: September 2024

The article reviews the jurisprudence on the compensatory and not punitive nature of the fiscal process. When it is assumed that the purpose of fiscal responsibility rulings is the recovery of public assets and not the punishment of the conduct, it is legally problematic to restrict the essential core of a fundamental right such as the right to due process and participation at some level of public management. The proposed interpretation is based on the Inter-American Convention on Human Rights and rulings of the Constitutional Court and the Council of State. At the end, some mechanisms are proposed to facilitate the recovery of the public resources committed.
Contribuciones de particulares a campañas electorales en colombia: ¿afinidad política o inversión de corto plazo?
Authors: Bautista Romero David
Published: September 2024

How do political campaigns financing and the subsequent election of their candidates affect decisions in state hiring? Donors’ resources are one of the most important sources of financing for public office candidates in Colombia, this could mean an additional form of citizen participation or an investment to later contract with the state. This paper analyzes the impact of financing successful electoral campaigns on the number of contracts subsequently obtained by their financiers. To this end, information was obtained on state contractors, in the periods 2012-2015 and 2016-2019, who contributed to campaigns in the framework of the 2015 regional elections. From the use of a difference-in-differences model, a significant increase in the number of total contracts obtained by campaign financiers whose candidates were winners was evidenced, as well as those modalities with simple and manipulable contracting processes, especially in the year following the election.
