Pemberdayaan UMKM sebagai strategi penguatan ekonomi masyarakat telah menjadi fokus utama pemerintah dalam meningkatkan kesejahteraan rakyat. Dengan menerapkan konsep green economy, terutama melalui ketahanan pangan, pemerintah berupaya meningkatkan kualitas hidup masyarakat dengan mempromosikan konsumsi ikan, salah satunya ikan lele. Ikan lele asap (salai limbek) menjadi salah satu sumber protein berkualitas tinggi, namun sayangnya merupakan makanan kelas premium karena harganya yang relatif mahal. Hal ini disebabkan oleh kendala seperti keterbatasan bahan baku ikan lele segar, lama proses pengasapan, dan produksi terbatas akibat jangkauan pemasaran yang masih terbatas. Hal tersebut dirasakan oleh UMKM Salai Limbek Nita, produsen ikan lele asap di Nagari Sungai Puar, Kabupaten Agam, Sumatera Barat. Untuk mengatasi permasalahan ini, tim pengabdi berdedikasi untuk membantu UMKM dengan kegiatan pelatihan dan pendampingan budidaya pembesaran ikan lele, pembuatan oven untuk meningkatkan kualitas proses pengasapan, desain kemasan dan labeling, serta membangun sistem e-commerce guna memperluas jangkauan penjualan. Pelatihan yang diikuti oleh 35 peserta dari unsur masyarakat, UMKM, perangkat nagari, tokoh masyarakat, dan petugas penyuluh kabupaten. Hasil kegiatan pengabdian mampu meningkatkan pemahaman dan kepuasan peserta pelatihan. Sementara bagi mahasiswa yang dilibatkan (program MBKM) terjadi peningkatan softskill dan hardskill melalui partisipasi dalam kegiatan PKM tersebut. Secara umum kegiatan ini diharapkan akan berdampak pada lingkup yang lebih luas yaitu terjadinya peningkatan ekonomi lokal dan kesejahteraan masyarakat secara keseluruhan

Spanish football clubs and social media visibility: The case of LaLiga EA Sports (2023/24 season)
Authors: Herrero-Gutiérrez Francisco-Javier
Published: July 2024

This article quantitatively analyzes the social media visibility of the football clubs playing in the First Division of the Spanish Football League, known as LaLiga EA Sports, for sponsorship purposes. The study is based on the analysis of the presence of the 20 teams playing in the 2023/24 season of LaLiga EA Sports, on the social networks Facebook, X, Instagram and YouTube. The “language used” in the Spanish social media accounts of these clubs is also studied as a variable on a sub-sample. The results indicate that 100% of the clubs analyzed have official accounts on Facebook, X, Instagram and YouTube. While some clubs are only present in these four social networks, some are present in up to eight. The article ranks the clubs according to number of followers on their social networks. In this regard, two clubs stand out above the rest: Real Madrid and FC Barcelona. On the other hand, in global terms, Instagram is the social network with the largest quantitative following. It was also found that all clubs follow a low number of accounts, although with very different proportions. Finally, with regards to the analysis of the “language” used in their Spanish social media accounts, the clubs use, as expected, Spanish, but also English and even the language of their autonomous community.
Myocardial bridge of the left anterior descending coronary artery as a cause of acute coronary syndrome and ventricular tachycardia in a young patient. Case report
Authors: Rudenko I. V. , Bezrodnyi A. B. , Mostbauer H. V.
Published: July 2024

Myocardial bridges (MM) are common congenital anomaly of the coronary arteries (CA) with the location of a separate bundle of myocardial muscle fibers over any epicardial vessel, most often over the middle segment of the left anterior descending coronary artery (LAD). In most patients, MM has a benign course, though in 25% of cases, it can cause stable or unstable angina, myocardial infarction with non‑obstructive CA (MINOCA), paroxysmal rhythm disturbances, and sudden cardiac death. The pathophysiological mechanisms of the development of fatal and non‑fatal cardiovascular events in such patients are heterogeneous and usually complex. They may include mechanical obstruction of blood flow, violation of diastolic relaxation of the CA, local hemodynamic changes in the tunnelled segment, endothelial dysfunction, vasospasm, damage to the atherosclerotic plaque located in the MM zone, and spontaneous dissection of the CA.
The purpose of our article was to present and discuss a clinical case of the development of MINOCA and potentially fatal ventricular arrhythmia in a 34‑year‑old man during competitive sports caused by MM in the LAD. MM was detected by invasive angiography. The diagnosis of MINOCA was established according to the criteria of the 4th universal definition of MI (clinical signs, ECG data, laboratory markers of myocardial damage). However, according to magnetic resonance imaging (MRI) of the heart 3 days after the onset of the disease, no inflammatory process, ischemic damage to the myocardium, and volume formations were found. At the same time, dilatation and hypertrophy of the left ventricle and myocardium fibrosis of non‑ischemic origin were present.
There is currently no generally accepted algorithm for examining a patient with MM. Because of the heterogeneity of the pathophysiological mechanisms of myocardial ischemia in this cohort of patients, it is suggested to use invasive and non‑invasive angiography, invasive methods of intracoronary imaging, Doppler assessment of coronary blood flow, and provocative stress tests to detect vasospasm.
Modern approaches to the choice of safe therapy of gallstone disease
Authors: Fadieienko G. D. , Kushnir I. E.
Published: July 2024

Gallstone disease (GD) is one of the most common digestive disorders. Its prevalence among the adult population of the developed countries of Europe and North America accounts near 20% and increases annually. The significance of this pathology is stipulated by not only medical, but also social aspects due to it often defeating persons of the most working age with the high rates of temporary and permanent incapacity due to the involvement of adjacent organs in the pathological process — liver, pancreas, stomach with further progression and development of complications. The article highlights physiological mechanisms of bile formation, as well as the main reasons for the gallstone’s formation in the gallbladder. Presented the data from the recent scientific research on the role of genetic factors and gastrointestinal microbiome, as well as functional disorders of the gallbladder, sphincter apparatus and inflammation in lithogenesis. The risk factors for the GD development, the stages of its formation and clinical manifestations are discussed. The treatment of GD depends on the presence of symptoms, disease duration, development of complications, gallbladder functional state, and on the degree of damage to the liver/biliary tract. It has been shown that 25% of GD patients, who develop recurrent clinical symptoms and/or complications, require laparoscopic cholecystectomy. At the same time, patients with asymptomatic GD course, elderly polymorbid patients, as well as patients with the initial GD stages require medical treatment. Pathogenetic approaches to the GD pharmacological treatment with the use of Ursonost and Mebsyn Retard® preparations have been discussed, in particular, the mechanisms of action of the drugs’ active substances, the indications for conducting litholytic therapy, the regimen of drugs’ administration and their safety in the prevention and treatment of symptomatic GD. The principles of dietary nutrition of patients with GD and the preventive role of some products in the regulation of bile rheological properties and gallbladder contractile function have been highlighted. Though minimally invasive surgery remains the most common method of GD treatment, therapeutic treatment with the use of molecules that affect the bile rheological properties, functional state of gallbladder and biliary system, should decrease the number of gastrointestinal complications and reduce the need for cholecystectomy. Therefore, future scientific research should be focused on the development of new preventive strategies for the prevention and treatment of gallstones in the general population and especially in patients with risk factors and comorbidities.

Authors: Fernández Martín , López Silvia Noemí
Published: July 2024

Phytosanitary management in ornamental plant production is based on the use of synthetic products causing negative effects on the environment. The aim of this work was to analyze the environmental impact (EI) of pest management in intensive ornamental production in the district of Moreno, province of BuenosAires. The phytosanitary management of three establishments (E1, E2 and E3) representative of the area was described. The applications were analyzed and the EI was quantified through the calculation of the Field Environmental Impact Quotient (EIQf), which considers the effect on beneficial fauna, workers and consumers. The EIQf values were variable (1172.90, 752.90 and 54.70 for E1, E2 and E3, respectively), due to differences in the doses and number ofapplications. Producers used insecticides/acaricides (42 %) and fungicides/bactericides (58 %) homogeneously. Similarity was also observed in the proportion of phytosanitary products used according to the toxicological class, applying twice as many compounds from classes III and IV than those from classes I and II. This is the first contribution on EI of phytosanitary products in ornamental productions in Argentina in general, and in the Moreno district in particular.

Authors: Fernández Wallace Trinidad , Zenobi Marcos , Bollatti Juan , Boetto Catalina , Salloum María Soraya
Published: July 2024

The stability of three slow-release urea products (SRU) and a non-protected granulated urea (U) product was assessed based on their Brix value and total Nitrogen (N) Kjeldahl concentration in water. Each SRU and U products (10 g) was mixed with 50 ml of distilled water at 23.5 °C for various durations: 1, 3, 6, 12, and 24 h. After each period of time, Brix values and total N concentrationswere measured in the aliquots. The N concentrations in all products exhibited time-dependent changes. A positive and linear correlation was observed between the total N in water and Brix values. The R2 between both methods was 0.97. Thus, the Brix value serves as a convenient and effective method to evaluate the relative rate of N release for different SRU products.

A new state policy in Russia aims to involve businesses in family and demographic issues. The importance of engaging enterprises in solving demographic problems is emphasized, as the state introduces re­levant regulations and incentives and publicizes results through the “Business Reputation Index of Business Entities (EKG-rating)”. Theoretically, these processes align with corporate citizenship theory, which posits that companies have an obligation to assume a share of responsibility proportional to their operational rights. This study examines how Russians of reproductive age view employers as potential influencers of demographic po­licy and how these views relate to their reproductive intentions. Data were collected in the autumn of 2023. The study found that 25 % of respondents believe that employer support for parents can increase birth rates in their regions. Overall, employers are seen to have a relatively minor influence on people’s reproductive attitudes. Those who appreciate employer support tend to delay having their first child. The perceived influence of employers is associated with an earlier ideal age for starting a family and a desire for more children. Moreover, those who see employers as influential tend to believe that having more children is essential for personal fulfillment. These findings suggest the potential for enhancing demographic policy by involving employers and underscore the importance of state policies that engage enterprises in regional demographic agendas.

Background: Malnutrition is a poor prognostic factor in a wide range of diseases. Nevertheless, there is a lack of data investigating the association between malnutrition and outcomes of patients with type B aortic dissection (TBAD) undergoing thoracic endovascular aortic repair (TEVAR). Therefore, the aim of the present study was to report the prevalence and clinical impact of malnutrition assessed by the controlling nutritional status (CONUT) score in TBAD patients undergoing TEVAR. Methods: The retrospective study indicated that a total of 881 patients diagnosed with TBAD and treated with TEVAR from January 2010 to December 2017 were categorized into subgroups based on their CONUT score (low ≤5 vs. high >5). To assess the correlation between malnutrition and early and follow-up outcomes of TBAD patients, logistic and Cox regression analysis were utilized, incorporating inverse probability weighting. Results: Malnutrition was present in 20.3% of patients according to the CONUT score. Multivariate logistic regression analysis revealed that pre-operative CONUT score modeled as a continuous variable was an independent risk factor for prolonged intensive care unit stay (odds ratio [OR], 1.09; 95% confidence interval [CI], 1.02–1.17; p = 0.015), 30-day death (OR, 1.43; 95% CI, 1.19–1.72; p < 0.001), delirium (OR, 1.11; 95% CI, 1.01–1.23; p = 0.035) and acute kidney injury (OR, 1.09; 95% CI, 1.01–1.16; p = 0.027). During a median follow-up of 70.8 (46.1–90.8) months, 102 (11.8%) patients died (high CONUT group: 21.8% vs. low CONUT group: 9.0%; p < 0.001). Multivariable Cox proportional-hazards models showed that malnutrition was an independent predictor for follow-up mortality (hazard ratio, 1.68; 95% CI, 1.11–2.53; p = 0.014). Results remained consistent across various sensitivity analyses. Conclusions: Malnutrition assessed by the CONUT score could profoundly affect the early and follow-up prognosis in patients undergoing TEVAR. Routine pre-intervention nutritional evaluation might provide valuable prognostic information.
Minimizing satellite residence time in the GEO region through elevated eccentricity method
Authors: Öz İbrahim
Published: July 2024

This research focuses on a critical aspect of the space environment, addressing the escalating issue of space debris and congestion in the geostationary orbit. The geostationary orbit is facing many satellites, leading to hazardous congestion levels and jeopardizing the limited resources available. Although organizations have established regulations for retiring satellites to graveyard orbits, a complete removal is not always achievable for numerous reasons. In response to this challenge, our study proposes a practical and cost-effective solution to mitigate debris accumulation in the region. In addition to the above, our research focuses on protecting the geostationary space environment, especially in unforeseen events involving inclined-operated satellites. We explore the implementation of an elevated eccentricity method, increasing the eccentricity of aging satellites and assessing its impact on their time in the geostationary and geostationary-protected regions. Our analysis encompasses short-term, medium-term, and long-term periods, enabling us to evaluate the effectiveness of this approach over different time frames. The study reveals a significant reduction in the time satellites spend in these regions as their eccentricity increases. Moderate eccentricity levels can reduce satellite residence time in these regions from 100.00% to 3.81%. This compelling evidence demonstrates the feasibility and effectiveness of adopting elevated eccentricity as a viable strategy to mitigate space debris in the regions. This proposed approach offers satellite operators a reliable and cost-effective solution, ensuring safe operations and protecting critical regions for aging GEO satellites. Accordingly, we contribute to space environment protection, securing the sustainability of the geostationary orbit.
A novel strategy to avoid local optimum: Army-inspired genetic algorithm (AIGA)
Authors: Kilinc Muslum , Atılgan Emrah , Atiş Cengiz
Published: July 2024

Objective functions of which an analytical solution is very difficult or time-consuming are solved using stochastic optimization algorithms. Those optimization algorithms compute an approximate solution for objective functions. For a specific search space, the objective function might have one or more local optima along with the global optimum. When a comparison is made among the algorithms, one optimization algorithm could be more effective than others in finding a solution for certain objective functions. The most important factors affecting the success of optimization algorithms are the greatness of search space and the complexity of the objective function. Reaching the global optimum in huge search spaces is very difficult. In complex objective functions that have many local optima or where the differences between global optimum and local optima are very small, the probability of trapping into the local optimum is high. Existing optimization algorithms could be improved using the search space scanned more successfully to give a better performance. To achieve this aim, we present a novel algorithm, called Army-Inspired Genetic Algorithm (AIGA), which is inspired from military movement. The presented algorithm, apart from other optimization algorithms, searches global optima effectively by dividing the entire search area into territories instead of searching in one piece. Thus, the probability of getting trapped in a local optimum reduces and the probability of finding the global optimum increases. The presented algorithm was tested on well-known benchmark problems. The results shows that AIGA is more efficient algorithm in finding the global optimum than traditional algorithms.

Published: July 2024

The present study investigated glyphosate adsorption-desorption in Malaysian sandy soil exposed to burning or applied with cow dung or rice husk ash (RHA). One gram each of the adsorbents (control, burnt soil, soil + cow dung, soil + RHA) was separately and in replicate mixed with solution of 20 mL of glyphosate at different initial concentrations (0, 25, 50, 100, 150, 200, 250 and 300 mg L-1), shaken for 24 hours, centrifuged at 10, 000 rpm for 10 minutes and later the decanted supernatants were collected. Desorption study follow immediately through addition of 20 mL of 0.01 M CaCl2 solution and then treated like adsorption study. Glyphosate analysis was done using high performance liquid chromatography with fluorescence detector and isotherm data was fitted to linear, Freundlich, Langmuir and Temkin models. Freundlich best fits the adsorption of glyphosate and application of cow dung or RHA enhanced the soil affinity for glyphosate. Freundlich isotherm constant (KF) for soils treated with RHA and cow dung were 9.768 mg g-1 and 6. 751 mg g-1, respectively as compared to 3.189 mg g-1 for the control soil. However, the greatest KF value (387.238 mg g-1) was recorded by burnt Benta soil. Glyphosate adsorption by both control and treated soils was favourable (0.044 < RL < 0.3). This study suggests that adsorption occurred through physical processes involving diffusion, complexation or ligand exchange. Glyphosate desorption from soils treated with cow dung and RHA was either hysteretic or reversible. Burning this soil should be discouraged due to its effect on increasing glyphosate mobility and possible groundwater contamination. Meanwhile, agricultural waste can be applied to this soil even though it might lead to an increased glyphosate mobility but because of its potential positive effect on the soil's biological functions, the glyphosate ions are bound to be degraded.

Authors: Kim Hyunjung , Lee Shinyoung
Published: July 2024

The purpose of this study is to investigate Korean students’ perception of sustainable development. Using raw data on students’ responses to the PISA 2018, this study analyzed Korean students’ responses to items related to sustainable development and compared these results with those from Canada and Singapore. PISA 2018 student questionnaire's items related to sustainable development were reclassified into environmental awareness, self-efficacy, sense of purpose, and action. Results revealed that students’ awareness of ‘climate change and global warming’ from all three countries was higher than that of ‘global health’, and their scores for environmental awareness were higher than their environmental self-efficacy. Regarding environmental self-efficacy and sense of purpose, Korea and Singapore showed a higher response than Canada. Among the three countries, Korea showed the highest participation rate in environmental actions due to Korea’s sociocultural and institutional characteristics. Students’ perception of sustainable development showed a mostly positive correlation with science achievement, and economic, social, and cultural status (ESCS), and the correlation with science achievement was higher. These results highlight that it is possible to identify Korean students’ perception of sustainable development and suggest implications for education in sustainable development.

Authors: Ham Yeajin , Hwang Jihyun
Published: July 2024

This study explored the impact of digital media and reading habits on student achievement. The analysis of data from the 2013 Korean Education Longitudinal Study, involving 6,525 eighth graders, employed latent profile analysis to categorize students' engagement with digital devices and books. The research aimed to understand the impact of varied literacy practices, encompassing both digital device usage and reading habits, on academic performance. Findings indicate that extensive book reading, as part of a balanced approach to literacy engagement, tends to be associated with higher academic performance when compared to relying solely or primarily on digital devices for accessing information. Furthermore, the findings suggested that utilizing digital devices was significantly linked to lower academic achievement even when utilized for educational and academic purposes. The intricate relationship between digital media use, reading activity, and academic achievement underscores the need for guidance for a balanced literacy engagement that incorporates both traditional book reading and digital modalities for a technologically advanced world.

Although South Korea recognizes the value of model use in science education, it is necessary to analyze how model use is reflected in science textbooks and in classrooms. This study examined the development and usage patterns of models in experimental activities in the geological, astronomical, and atmospheric domains in three Korean elementary school science textbooks. A coding framework was developed and analyzed based on previous studies and science curricula in other countries. The study found that, first, the model development and usage patterns in experimental activities in the geological, astronomical, and atmospheric domains in science textbooks were largely similar, although some differences existed across domains. Second, the resources required for model development and development methods; evidence-based model development, evaluation, and modification; and the cyclic features of modeling were similar across the three domains, but the geological domain was characterized by model limitations and the astronomical domain was characterized by the process of investigating a phenomenon. Based on these f indings, the study discussed model development activities in textbooks can be improved.

Judgments about the presence or absence of discrimination are generally made in a contextof considerable uncertainty. Here, we apply Signal Detection Theory, a framework thatmodels decisions under uncertainty, to attributions to discrimination in order to differentiatebetween sensitivity (i.e., the ability to differentiate between situations with and without cuesto discrimination) and response bias (i.e., a relative tendency to make liberal rather thanconservative judgments about the presence of discrimination) in such judgments. To do so,we developed a new paradigm and used it to examine participants’ attributions to genderdiscrimination by manipulating the gender of victims and observers and the harm of theaction (Experiment 1), the direction of gender discrimination (Experiment 2), thediscrimination context (Experiment 3) and participants’ decision task (Experiment 4).Participants’ response bias was consistent with cultural stereotypes about genderdiscrimination and was affected by the actual base rate of discrimination in the experimentalcontext which they picked up explicitly only in the context of discrimination. The harmimplied by the action in question affected participants’ response bias such that they weremore liberal in cases in which victims were harmed, with small corresponding differences insensitivity. Our flexible and broadly applicable new paradigm opens up new possibilities forfurther research on attributions to discrimination and their analysis in terms of sensitivityand response bias.

The Trier Social Stress Test (TSST) is one of the most frequently used laboratory stressors. Previous meta-analyses concluded that the TSST induces moderate but robust psychobiological stress responses in both adult and, recently, youth samples. With the present study, we focused on the salivary cortisol response and performed both a systematic review comprising 143 studies and a meta-analysis with 91 studies (N=8291 participants) (a) to investigate which and how different TSST variants have been used in children and adolescents (b) to provide an updated overview of the reported effect sizes, and (c) to identify previously reported and new potential moderators. Our results showed that TSST characteristics have been reported inconsistently, with generally similaradministration characteristics for the major TSST versions TSST for Children (TSST-C), TSST Modified (TSST-M), and the original TSST regarding participant exclusion, administration time, preparation, total TSST duration, and jury set-up. After correcting for publication bias using PEESE residuals, we found the TSST to be an effective tool for inducing a salivary cortisol stress response (Hedge’s g = 0.56, p<.0001). Moderation analyses revealed that participant gender, number of judges, and the TSST’s total duration were significant moderators. Explorativelyspeaking, higher baseline cortisol levels predicted lower baseline-peak reactivity. Overall, the TSST (with its specific adaptations) is a suitable instrument for inducing acute psychobiological stress responses in children and adolescents. In the interests of open and reproducible science, establishing reporting standards for both methods and results would be desirable for future studies to enable more robust moderation analyses.

The study aimed to determine if the pain assessment skills of the individual being observed influence observationally induced placebo effects in pain. Participants were randomly assigned to two experimental groups and one control group. In the experimental groups, participants observed the responses to the placebo of a model who had previously shown either high accuracy (high-accuracy group) or low accuracy (low-accuracy group) in differentiating the intensity of pain stimuli. The model exhibited less pain in response to pain stimuli when a placebo was administered, and more pain when no placebo was given. The control group did not observe anyone experiencing pain during the experiment. All participants then received a series of pain stimuli of the same intensity, half of which were administered with a placebo, and rated the intensity of pain. Pain-related expectations of the participants were also measured. Observational learning caused a form of nocebo hyperalgesia in the participants, leading to an increase in pain in a context that had previously accompanied the model’s heightened pain sensations. This effect was only observed in participants from the high-accuracy group. Observational learning resulted in pain-related expectations, regardless of the observed model’s accuracy. However, these expectations mediated participants’ responses to pain only in the low-accuracy group. The findings suggest that the pain assessment skills of the observed model play a significant role in shaping observers’ pain-related expectations and their responses to a placebo.
Variation in brain aging: A review and perspective on the utility of individualized approaches to the study of functional networks in aging

Healthy aging is associated with cognitive decline across multiple domains, including executive function, memory, and attention. These cognitive changes can often influence an individual’s ability to function and quality of life. However, the degree to which individuals experience cognitive decline, as well as the trajectory of these changes, exhibits wide variability across people. These cognitive abilities are thought to depend on the coordinated activity of large-scale networks. Like behavioral effects, large variation can be seen in brain structure and function with aging, including in large-scale functional networks. However, tracking this variation requires methods that reliably measure individual brain networks and their changes over time. Here, we review the literature on age-related cognitive decline and on age-related differences in brain structure and function. We focus particularly on functional networks and the individual variation that exists in these measures. We propose that novel individual-centered fMRI approaches can shed new light on patterns of inter- and intra-individual variability in aging. These approaches may be instrumental in understanding the neural bases of cognitive decline.
Inequalities in pre-school learning contexts by immigrant background

In many Western countries, children with foreign-born parents are lagging behind children with native-born parents in school performance. In the policy debate much hope is placed on the potential of pre-schools to remedy this, by providing a learning and language environment that can compensate for the disadvantages that these children face. We study inequalities in pre-school learning contexts by immigrant origin, using full population register data that matches all children to their families and pre-schools. Enrolment in pre-school is lower for children of immigrants, but this is – surprisingly – almost entirely driven by low enrolment of children in non-refugee families. Contrary to expectations, children from origin groups with larger school difficulties have high pre-school enrolment rates. Our results suggest that explanations for low enrolment should primarily be sought in intentions to remain long-term in the host country.In pre-schools, immigrant background children have a somewhat higher teacher density, but a somewhat lower density of qualified teachers, and a somewhat higher turnover rate and sickness absence among teachers. These differences are however small. Where we see large differences is in the composition of the child and teacher group: Immigrant-background children go to pre-schools where a much higher proportion of teachers and children have immigrant background. We conclude that hopes to equalize school outcomes through encouraging pre-school enrolment are misplaced, and equalizing structural indicators is unlikely to make a big difference. The compensatory potential of pre-schools lies primarily in a de-segregation of staff and children across pre-schools.
