Authors: Putrini Camelia , Prasetyo Agus , Hartanto Hartanto
Published: March 2023

This study examines the accountability of village fund management as the sole source of funding in an era of economic hardship brought on by the Covid-19 pandemic in support of the Village SDGs policy. Because the research target was in one of the Covid-19 pandemic's black zones in Indonesia, the study used a qualitative method with internet interviews. To achieve accountability, the Village government avoids abuse of authority by the village head as the highest authority in the management of the Village Fund, encourages community participation and transparency in the Village Fund management process, and implements programs in accordance with the village typology as an independent village. Finally, the village adopted reporting processes in compliance with applicable regulations and made proper use of SISKEUDES as policy accountability implementation. According to the research, village funds are a solid source of funds to support the Village SDGs agenda. Accountability for village fund management is a critical issue that must be considered to ensure the sustainability of village funds.

In a piping system makes it possible to add branching into an existing piping system. In this research will discuss about installation 12 " branch pipe in to 16” existing pipe. The system should be installed without interrupting the operation of the pipeline to avoid huge losses. Hot-tapping is a technology that works to create branching on the online service pipe condition. Calculation and analysis of the results to ensure the process of hot-tapping absolutely safe to operate. parameters that must be considered include the heat input, the operating pressure during welding hot-tapping process with Shielded Metal Arc Welding, stress that occurs at the branching system. Analysis on split tees must be done because of stress that occurs due to the welding process and the reduction in thickness. Analysis on the plumbing system must be done because of a new branching thus causing new stress. The results of the analysis on split tees and the pipe system is used as a reference-making procedures for implementing hot-tapping. Maximum stress that occurs in the pipes during hot-tapping process is the welding area (22.828 psi). The welding process causes melting partial in the metal pipe so, during welding process (hot-tapping) working pressure should be reduced by 25.27%. The condition of the fluid in the existing pipeline still safe because liquefaction as a result of the welding process does not penetrate to the inner pipe. The new design results in branch pipe eligible to fabricated because stress that occurs is still below the allowable stress values

Published: March 2023

Selective kappa-opioid receptor (KOR) agonists are considered a promising group of substances for developing opioid analgesics characterised with an original mechanism of action without the risk of respiratory depression and drug addiction. Previous studies identified a fluorophenyl derivative of imidazo[1,2-a]benzimidazole (RU-1205) with a KOR-based mechanism of analgesic action established in in vitro and in vivo experiments.

The aim of the study was to assess the effect of 9-(2-morpholinoethyl)-2-(4-fluorophenyl)imidazo[1,2-a]benzimidazole dihydrochloride on the level of DNA damage in rats after a single subcutaneous injection.

Materials and methods. The study was conducted in adult white outbred laboratory rats of both sexes. DNA damage was estimated using the comet assay. The study involved a single subcutaneous injection of an aqueous solution of RU-1205 in three doses: 1, 10, and 100 mg/kg. The authors used intraperitoneal methyl methanesulfonate (40 mg per kg of animal body weight) as a positive control and 0.9% NaCl  (100 μL per 100 g of animal body weight) as a negative control.

Results. A single subcutaneous injection of RU-1205 to rats did not produce a significant dose-dependent increase in % tail DNA when compared with the state of   the corresponding organ/tissue cell genome in negative control animals after normal saline administration at the same time points. In the negative control groups, % tail DNA in cells of various organs/tissues ranged from 1.83% to 3.82% (median values [25–75%]). On the contrary, the administration of 40 mg/kg of genotoxic methyl methanesulfonate led to an increase in damaged DNA in all studied organs and tissues when compared with negative control animals.

Conclusions. The study of 9-(2-morpholinoethyl)-2-(4-fluorophenyl)imidazo[1,2-a] benzimidazole dihydrochloride genotoxicity demonstrated that a single subcutaneous injection of 1, 10, or 100 mg/kg of RU-1205 to rats did not damage the cell genome of the studied organs.

Authors: KURTULMUŞ Zeynep , ŞAMLI Hacı Ömer
Published: March 2023

This study aimed to determine how preschool teachers handle mathematics learning processes in their mathematics activity plans and which contents they include. The study used the document analysis method as a descriptive research model. The study examined 200 mathematics activity plans applied by 10 preschool teachers working in preschool education institutions in the 2020-2021 Fall and Spring academic terms. The data of the study were collected with the Mathematics Activities Assessment List (AEL), which the researchers developed. The researchers analysed the data obtained in the study separately by using the coding system without specifying the teachers' names for confidentiality. As a result, the researchers determined that preschool teachers planned mathematics activities mainly in large group activities and integrated them into their activity plans. On the other hand, they also found that teachers included concepts such as number/counting and quantity more in their mathematics activity plans and they planned mathematics activity plans as classroom activity plans. In addition, they included family participation activities in mathematics activity plans.

Authors:   İstanbul Medeniyet University, İstanbul, Turkey, Ermağan Elif
Published: March 2023

Preschool education describes the education process of the child until primary school, and it is also within the scope of child bilingualism. This study examined the studies on bilingualism covering the preschool period in Turkey. The main statement of this study is that related postgraduate theses in different disciplines investigating the issue of bilingualism covering the preschool period are insufficient in the national literature in Turkey. This study aimed to analyze postgraduate theses between 2003 and 2022 registered in the Turkish Higher Education Institution (YÖK) database and to break down different variables. The main findings are that bilingualism studies are mostly concentrated on master's theses, they are not the subject of doctoral theses. Furthermore, education- and teaching-oriented theses are at the forefront and should be handled together with other disciplines. The model of the study is a qualitative case study, and the data of the study were obtained from theses on the website of YÖK. In the analysis of the data, the bibliometric technique is used, and statistics about the subject are created.

Published: March 2023

The diversity of topics in education makes it difficult for artificial intelligence (AI) to address them all in depth. Therefore, guiding to focus efforts on specific issues is essential. The analysis of competency development by fostering collaboration should be one of them because competencies are the way to validate that the educational exercise has been successful and because collaboration has proven to be one of the most effective strategies to improve performance outcomes. This systematic review analyzes the relationship between AI, competency development, and collaborative learning (CL). PRISMA methodology is used with data from the SCOPUS database. A total of 1,233 articles were found, and 30 passed the inclusion and exclusion criteria. The analysis of the selected articles identified three categories that deserve attention: the objects of study, the way of analyzing the results, and the types of AI that could be used. In this way, it has been possible to determine the relationship offered by the studies between skill development and CL and ideas about AI’s contributions to this field. Overall, however, the data from this systematic review suggest that, although AI has great potential to improve education, it should be approached with caution. More research is needed to fully understand its impact and how best to apply this technology in the classroom, minimizing its drawbacks, which may be relevant, and making truly effective and productive use of it.

Published: March 2023

The management system of agricultural consumer supply and marketing cooperatives is considered. This system is a structure containing three levels of hierarchy: the first level includes control elements; the second level contains agricultural business representatives of the middle level; the third level includes agricultural producers. The article shows that the business processes of the agricultural producer and in his interaction with customers are end-to-end. The paper describes the flows of informational and material nature from an agricultural consumer supply and marketing cooperative (an integrator farm) to a personal subsidiary plot and from a personal subsidiary plot to an agricultural consumer supply and marketing cooperative (an integrator farm). Four structural and functional models of an agricultural consumer supply and marketing cooperative are created: one which is organised on the basis of an integrator farm; one which has an associated member, that is a processing enterprise; one which includes credit or insurance agricultural consumer cooperatives; one which sells products through chain stores. The analysis of the information exchange mechanisms during the agricultural producers’ integration is carried out. Moving material and financial flows within the models are presented. It is shown that the created models are necessary for developing route maps of business processes for reporting information in business logics language.
WORLD COURT'S VERDICT TOWARDS BAKASSI PENINSULA: PORTRAYING GAINS AND LOSSES
Authors: Achuo Kpwa Stephen
Published: March 2023

Border discords are one of Africa's unending vestiges of European colonialism/imperialism; the Bakassi peninsula dispute between Cameroon and Nigeria was one of such. The subsequent discovery of large deposits of natural resources in the Bakassi region made Cameroon and Nigeria to engage into claims and counterclaims, bilateral diplomacy, military skirmishes, and finally resorting to the World Court or International Court of Justice (ICJ) for judgement. After eight years of deliberations, the court finally adjudged and declared that Bakassi belongs to Cameroon, sparking widespread criticism from Nigeria. Popular opinion in Nigeria held/holds that Nigeria benefited little or nothing following the ICJ verdict of October 10, 2002 and that Cameroon gained exponentially.  Thus, the premise of this paper is to outline the gains and losses of both Nigeria and Cameroon following the International Court of Justice’s ruling, and to debunk the Nigerian perception of the verdict being partial and willy-nilly in nature. Using the qualitative method of research, secondary data based on previous research on the Bakassi saga was used. Using content analyses on the secondary data obtained, observations were made on what both Cameroon and Nigeria lost or gained after the World Court's verdict over the Bakassi peninsula. In its findings, this paper proffers that the gains and losses accruing to both countries are evenly distributed. This research can be a springboard for Cameroon and Nigeria to look beyond their gain and losses, and jointly carryout developmental activities in the Bakassi peninsula so as avoid future ethno-nationalistic tendencies in the area

Published: March 2023

This study has three objectives- to identify the socio-economic difference between the empty nest and non-empty nest rural elderly, to find out the difference between them based on their relationship with their children, and to differentiate the pattern of mental anxieties between them. The social survey method has been applied for data collection. For the empty-nest elderly, the researcher has selected three villages under the district of Jhenaidah. The non-empty-nest elderly researcher has established Shatoil village under the district of Naogaon. Data were collected from a total of 132 (100 non-empty-nest and 32 empty-nest) respondents using purposive sampling with informed consent. A semi-structured interview schedule was applied to collect the data. In this study, most empty-nest respondents' socio-economic conditions were satisfactory, but non-empty-nest respondents' socio-economic conditions were not. In both cases, the highest of the (empty-nest and non-empty-nest) respondents’ relationship with children was good and had no difference. The main difference between them is in the case of service providers. The greatest of the non-empty-nest elderly did not feel loneliness and mental anxieties. On the other hand, all the empty-nest respondents felt lonely and most suffered from mental anxietyanxieties. GOs and NGOs should build up adult recreation centers and old homes and train elders on using modern technology (such as Facebook, WhatsApp, Messenger, Skype, etc.) to communicate with children. It will mitigate their loneliness and mental anxiety

Persepsi Mahasiswa Institut Bisnis dan Informatika Kosgoro 1957 Terhadap Kualitas Pelayanan di Program Studi Administrasi Bisnis
Authors: Dhamayanti Sylvia Kartika
Published: March 2023

This study aims to examine the perceptions of Kosgoro 1957 Institute of Business and Informatics students' perceptions of the service quality of the Business Administration Study Program. The sampling method used is a simple random sampling method organized by educational staff. The research informants consisted of 100 students who had received and are currently receiving academic administration services. The perception assessment method uses the scoring method and continues with the perception category based on the score that has been generated. Student perceptions of service expectations are not matched by the performance of educational staff, they argue that the quality of services provided is quite optimal. These findings indicate that perceived service quality is less than student expectations on several service quality dimensions. Namely, tangible, reliability, responsiveness, assurance and empathy. Therefore, to improve the quality of service to students, what needs to be improved is; (1) standard operating procedures (SOP); (2) speed and timeliness of service; (3) discipline of educational staff.

The purpose of this article is to test the hypothesis that the share of financially fragile firms in the US is growing along with the approaching macroeconomic or financial crisis. Two criteria were used to measu­re financial fragility. According to the Mulligan criterion, the speculative financing regime dominated the US private sector, and according to the Davis with coauthors criterion, it was the hedge regime. The low share of Ponzi firms — compared to countries that implemented austerity policies (e. g. Greece, Portugal and the Netherlands) — could be explained by the US government’s expansionary fiscal and monetary policies, which sought to maintain the revenue of the US private sector at an ‘acceptable level’ in the times of crisis. The most fragi­le industry was consumer cyclicals, and the least fragile, healthcare. Our econometric analysis, based on panel-based fixed-effects logistic regression, demonstrated that the probability of becoming a Ponzi-financed firm — according to the Mulligan criterion — is affected by the amount of its debt, the presence or absence of a crisis in a particular year, its total capital stock, and net income after tax. Thus, the financial instability hypothesis — tested against the Mulligan criterion in the form of the interest coverage ratio — is confirmed for private US firms: for several years, before the onset of both crises considered, the number and share of Ponzi firms grew steadily. The accumulation of financial fragility before, during, and after the Great Recession — measured according to the criterion described in Davis et al. — does not fit the logic of the financial instability hypothesis: the dynamics of the number and share of Ponzi firms is not related to cyclical fluctuations in GDP.
What is Stable Knowledge?
Authors: Varakin D. N.
Published: March 2023

The paper investigates the problem of knowledge stability. The purpose of the article is to analyze the theoretical prerequisites for knowledge stability in the economy and society. The study considers the hypothesis about the existence and applicability of stable knowledge in the economy. There are several types of stability: stability in mechanical media, in complex nonlinear systems, asymptotic stability, stability based on the energy criterion, and stability in the institutional environment. “Mechanical approaches” to the stability of economic structures as well as data-driven approaches in management are not considered by the author as comprehensive enough to describe super-complex processes in nonlinear open systems. The article criticizes theories that do not give due regard to the explosive nature of knowledge, setbacks in development, and the existence of limits to growth. Methodologically, the study relies on the synthesis of systemic and synergistic approaches in economics. The research novelty stems from the fact that the study showcases the significance of chaos for knowledge-intensive activity and discusses threats to the stability of the economy and society. The study singles out two types of knowledge with unifying and separating properties. The author links these properties to the specifics of light in physics: civilizational knowledge is like a wave while competitive knowledge is like a particle. A particular emphasis is laid on those properties of knowledge that are based on its “quantum nature”. In this case, small things (knowledge) can control big things, they can completely transform the entire structure and disrupt the stability of the old institutional frameworks. The study puts forward the concept of knowledge genesis as a theoretical and practical transition of stable knowledge into practice. In conclusion, the dangers of reductionist tendencies in economic theory are outlined and avenues for further research are highlighted.
Understanding the Modern World with Marx's Political Economic Critical Thinking

How relevant is Marxist economic theory to the problems of today’s world? Did those contradictions that Marx analyses in his Das Kapital disappear? The answer is clear: no, but they have now acquired a larger scale involving some new actors. The faster pace of economic globalisation at the end of the last century has been accompanied by the cross-border development of class relations. Resting on large-scale cross-border operations of transnational corporations, capital is now contributing to the formation of a transnational capita­list class. In today’s world there are new, contradictory relations based on a multitude of inherent contradictions, rendering the world situation more complex: the rich-poor gap brought about by the formation of the transnational capitalist class; the transnational capitalist class and the question of its global hegemony; and the relationship between the transnational capitalist class and the world system. All these factors are of economic nature but their impact goes beyond the economic sphere. The resulting hegemony of the transnational capita­list class pushes the world situation in the direction of economic politicisation and further political militarisation. It is clear that our world is still dominated by the capital, which was discussed by Marx in his critique of political economy. This approach still provides the basic framework for understanding and examining our era.

Background: Glioma has a high incidence in young and middle-aged adults and a poor prognosis. Because of late diagnosis and uncontrollable recurrence of the primary tumor after failure of existing treatments, glioma patients tend to have a poor prognosis. Recent advances in research have revealed that gliomas exhibit unique genetic features. Mitogen-activated protein kinase 9 (MAPK9) is significantly upregulated in mesenchymal glioma spheres and may be a new target for glioma diagnosis. This study aimed to investigate the potential diagnostic significance and predictive value of MAPK9 in glioma. Methods: Paraffin-embedded tumor tissues and paracancerous tissues were collected from 150 glioma patients seen at the General Hospital of Northern Theater Command. Immunohistochemistry and western blot assays were used to detect the expression levels of MAPK9. Prognosis and survival analyses were performed using SPSS 26 software for univariate/multivariate analysis and log-rank analysis. Cellular models were used to assess the effect of MAPK9 overexpression and knockdown in vitro. Results: MAPK9 expression was higher in glioma tissues than in paraneoplastic tissues. Prognostic and survival analyses revealed that the MAPK9 expression level is an independent prognostic factor in glioma patients. In addition, overexpression of MAPK9 significantly promoted the proliferation and migration of primary glioma cells, possibly via the Wnt/β-catenin-regulated EMT pathway. Conclusions: MAPK9 is an independent prognostic factor in glioma and is involved in tumor progression.
CRRESS - Session 4 - Reproducibility and confidential or proprietary data: can it be done?
Authors: Guimaraes Paulo
Published: March 2023

What happens to reproducibility when data are confidential or proprietary? Many journals can only ask that detailed access procedures be provided in a ReadMe file, but what mechanisms could be used to conduct computational reproducibility checks on such data? Should authors temporarily share their data with the journal for the purposes of reproducibility verification, even if they are not part of the public data replication package? Is it feasible to use a network of "insiders" to run code provided as part of a data replication package to assess reproducibility? Could a "certified run" be used?
Stationary surface waves and antidunes in dense pyroclastic density currents

Published: March 2023

Stationary antidunes are a product of critical flow in open channel systems, but with poor preservation potential. They are related to the existence of stationary surface waves in the overriding current, but their existence in the dense pyroclastic density current regime has been unrecognized to date. Experiments presented here demonstrate that surface waves in simulated dense pyroclastic density currents show both supercritical downstream-migrating and critical stationary wave behaviour. Deposits from the Pozzolane Rosse ignimbrite (Italy) demonstrate the presence of stationary wave antidunes in deposits from dense pyroclastic currents which imply progressive aggradation from long-lived quasi-stable critical flow conditions during their emplacement. The narrow stability fields for the formation of these deposits reinforces that they are unlikely to be widely preserved in the geological record, but highlights that dense pyroclastic density currents cannot be assumed to be simply supercritical flows, and they may be substantially slower than over-riding dilute currents.
Experimental Manipulation of Visual Attention Affects Muscularity Perception

Published: March 2023

Objective: Sustained attention to high- or low-adiposity bodies has been shown to influence perceived body size and body dissatisfaction, but it is not known whether attention also affects the perception of muscularity. Determining the relationship between attention, muscularity perception and body dissatisfaction may to explain why only some individuals develop muscularity-related body image disturbance, despite similar exposure to idealised bodies.Method: Eighty-one participants adjusted the muscularity of body stimuli to appear ‘normal’ and completed the Drive for Muscularity Scale (DMS) – a measure of body dissatisfaction. Next, they were exposed to simultaneously presented images of high- and low-muscularity bodies. Separate groups of participants were instructed to attend either to the high- or the low-muscularity body. Finally, participants repeated the body stimulus adjustment task and DMS.Results: Participants who attended to the high-muscularity body perceived subsequently-presented bodies to be significantly less muscular, while those who attended to the low-muscularity body perceived them to be significantly more muscular. However, no significant change in body dissatisfaction was observed in either group.Discussion: These findings parallel those for attention to high or low-adiposity bodies and are consistent with the suggestion that visual attention may be important in the development of body size and shape misperception – a key feature of mental health issues such as eating disorders and muscle dysmorphia. This insight opens new avenues for the potential development of treatments for body size and shape misperception and its associated disorders, based on directing attention away from extreme muscular ideal bodies and towards more representative bodies.
How do Students' Cognitive and Motivational Characteristics Relate to Experimentation Skills and Conceptual Understanding during Scientific Inquiry

Inquiry learning relies on students’ engagement, which is driven by their cognitive and motivational characteristics. The role of student characteristics for inquiry learning has been sparingly investigated and only from a variable-oriented perspective. In contrast, this study employed a person-centered approach to investigate the combined influence of students’ cognitive and motivational characteristics in relation to experimentation skills and conceptual understanding during guided inquiry learning. All students (N = 110, Mage = 12.07) attended a lesson about photosynthesis and worked on a structured inquiry task individually. Experimentation skills were measured by the proportion of controlled experiments that students conducted. Conceptual understanding comprised students’ written argumentation and conceptual knowledge posttest scores. We identified three distinct clusters, based on students’ prior knowledge, self-concept, and interest – Underestimating, Struggling, and Strong. Although Struggling students conducted a significantly higher proportion of controlled experiments than Strong students, Underestimating and Strong students outperformed them in the conceptual knowledge posttest. We found no differences in argumentation quality. These findings suggest that highly guided tasks might not be equally suitable for students with different levels of interest, prior knowledge, and self-concept and attest to the benefits of using person-oriented methods. Therefore, students’ motivation needs to be considered in addition to their prior knowledge when designing guidance for inquiry learning.
