Authors: Cristina Natalia Yuliana , Rahardjo Djoko , Kisworo
Published: September 2023

Sungai Opak merupakan salah satu sungai utama di Provinsi Daerah Istimewa Yogyakarta yang berpotensi tercemar akibat aktivitas pembuangan limbah kegiatan pertanian dan industri penyamakan kulit yang berada di daerah aliran sungainya. Masuknya logam berat kromium yang terkandung dalam limbah ke badan air dapat memicu akumulasi kromium pada biota air. Penelitian ini bertujuan untuk mempelajari karakteristik kualitas air, keragaman ikan, sebaran akumulasi kromium, dan hubungan konsentrasi kromium dalam air dan sedimen dengan tingkat akumulasi kromium pada ikan di muara Sungai Opak. Penelitian dilakukan pada tiga stasiun sampling yaitu: bagian atas, tengah dan bawah muara Sungai Opak. Proses ekstraksi sampel air dilakukan dengan metode standar APHA/AWWA/WEF, sedangkan ekstraksi sampel padat (sedimen dan ikan) dilakukan dengan metode asam. Pencemar kromium ditemukan pada semua sampel ikan, air, dan sedimen. Perairan muara Sungai Opak telah tercemar oleh nitrat, fosfat dan kromium, sedangkan sedimen dan ikan di muara Sungai Opak telah tercemar oleh kromium. Sampel sedimen memiliki konsentrasi kromium paling tinggi dengan kisaran sebesar 1,140 – 4,328 mg/kg, diikuti sampel ikan dengan kisaran sebesar 0,108 – 0,919 mg/Kg dan terendah pada sampel air dengan kisaran sebesar 0,108 – 0,211 mg/L. Konsentrasi kromium pada air dan sedimen tidak berpengaruh secara signifikan terhadap akumulasi kromium pada ikan berdasarkan titik sampling. Akumulasi kandungan krom dalam 12 jenis ikan di muara Sungai Opak masih memenuhi standar baku mutu yang ditetapkan oleh Dirjen BPOM No. 03725/ B/ SK/ 89 sebesar 2,5 mg/kg. Perlu dilakukan penanganan lebih lanjut terkait bahaya akumulasi kromium dalam ikan yang dapat menimbulkan masalah kesehatan apabila terkonsumsi oleh manusia dalam jangka waktu yang lama
The social protection of children and youth in Colombia: interpretive review
Authors: Noreña Herrera Camilo , Munoz Echeverri Ivan Felipe
Published: September 2023

Introduction: The rights of social protection policies for children and youth need to be discussed for their strengthening to guarantee universality or to create new forms of that policies. Method: Documentary review supported by content analysis techniques and interpretive analysis of four social protection systems for children and youth: integral social security, family subsidy, social assistance, and the national system of family welfare. For the analysis, theoretical-political references to universal social protection and the doctrine of the protection of the rights of children and young people were considered. Results: The social protection systems analyzed are described in terms of implementation mechanisms, participation of children and youth criteria, financing, and rectory. The life course approach and its universality, institutional appropriation, and participation of children and young people were discussed. Conclusion: The social protection systems analyzed show social protection strategies for children and young people within the framework of the Social Constitutional State, but they are implemented through welfare, compensatory and targeted policies that contrast the perspectives of needs with that of the protection of children’s rights, and provide insufficient support for the principles of equality, participation, and universality.
CD39+MDSC Facilitates Cisplatin Resistance of Ovarian Cancer Cells by
Affecting Adenosine Synthesis
Authors: Ma Jiong , Zhou Chunxia , Zheng Xia , Chen Xuejun
Published: September 2023

Background::

Chemoresistance is a major cause of relapse or death in ovarian cancer (OC) patients.
New evidence suggests the crucial role of myeloid-derived suppressor cells (MDSCs) in mediating chemoresistance
of cancer cells. We aimed to dissect the way MDSCs affect the cisplatin resistance phenotype of OC and
the related mechanisms.

Methods::

MDSCs were isolated from the spleen of OC mice isograft. CCK-8 and colony formation assays revealed
the effects of an MDSC-conditioned medium with dysregulated CD39 on the proliferation and cisplatin
sensitivity of OC cells. Fluorescence assay was used to reveal the effects of MDSCs with dysregulated CD39
on adenosine triphosphate (ATP) hydrolysis and adenosine (ADO) synthesis.

Results::

MDSCs with highly expressed CD39 could facilitate the proliferation and cisplatin resistance of OC
cells, while MDSCs with downregulated CD39 caused the opposite results. In addition, MDSCs with upregulated
CD39 could facilitate the hydrolysis of immunogenic ATP to immunosuppressive ADO, while the introduction
of CD39 inhibitor could repress such hydrolysis of ATP and generation of ADO, thereby abating the
proliferation and cisplatin resistance of OC cells.

Conclusion::

CD39+MDSC could promote the proliferation and cisplatin resistance of OC cells by generating
high concentrations of ADO, which indicates that targeting CD39+MDSC might be a feasible way to improve
cisplatin resistance in OC.

Biotransformation Activity on Saponins
Authors: Li Pengfei , Ling Xiaofeng , Zhao Shujuan , Xu Lili , Wang Rufeng
Published: September 2023

Objectives::

This study reports the diversity and community structure differences of
the endophytic fungi of Panax japonicus of different ages to obtain novel endophytic fungi with
glycoside hydrolytic activity for rare saponins production.

Methods::

This study used the high-throughput sequencing method to analyze the diversity and
community structure of endophytic fungi of P. japonicus. The endophytic fungi were processed
by traditional isolation, culture, conservation, and ITS rDNA sequence analyses. Then the total
saponins of P. japonicus were used as the substrate to evaluate the glycoside hydrolytic activity.

Results::

The composition analysis of the community structure showed that the abundance, evenness,
and diversity of endophytic fungi of nine-year-old P. japonicus were the best among all
samples. A total of 210 endophytic fungi were isolated from P. japonicus samples and further
annotated by sequencing the internal transcribed spacer. Then the biotransformation activity of
obtained strains was further examined on total saponins of P. japonicus (TSPJ), with a strain
identified as Fusarium equiseti (No.30) from 7-year-old P. japonicus showing significant glycoside
hydrolytic activity on TSPJ, including ginsenoside Ro→zinglbroside R1, pseudoginsenoside
RT1→pseudoginsenoside RP1, chikusetsusaponin IV→tarasaponin VI and chikusetsusaponin
IVa →calenduloside E.

Conclusion::

These results reveal the diversity and community structure differences of the endophytic
fungi of P. japonicus with different ages and establish a resource library of endophytic
fungi of P. japonicus. More importantly, we identified a valuable endophytic fungus with glycoside
hydrolytic activity and provided a promising convenient microbial transformation approach
to produce minor deglycosylated ginsenosides.
Exosome miR-30a-5p Regulates Glomerular Endothelial Cells' EndMT
and Angiogenesis by Modulating Notch1/VEGF Signaling Pathway
Authors: Ning Yaxian , Zhou Xiaochun , Wang Gouqin , Zhang Lili , Wang Jianqin
Published: September 2023

Background:

Diabetic nephropathy (DN) is one of the microvascular complications of
diabetes. Endothelial-mesenchymal transition (EndMT) and endothelial damage lead to abnormal
angiogenesis in DN.

Objective:

This study aimed to investigate the role of exosome miR-30a-5p in high glucose
(HG)-induced glomerular endothelial cells (GECs) dysfunction and explore the underlying mechanisms.

Methods:

GECs were cultured in normal glucose (5.5 mM) and HG (30 mM) conditions. The recipient
GECs were transfected with exosome or miR-30a-5p mimic/inhibitor and then detected by
using CCK-8 and flow cytometry assay. Luciferase analysis was used to verify miR-30a-5p acted
on notch homolog protein 1 (Notch1). RT-qPCR and Western blot were used to detect the expression
of VE-cadherin, α-SMA, vascular endothelial growth factor (VEGF) and Notch1. In vivo, exosome
miR-30a-5p was administered to DN mice, and periodic acid-Schiff (PAS) staining, UTP
levels, and HbA1c levels were measured.

Results:

The expression of miR-30a-5p was downregulated in HG-treated GECs. Exosome
miR-30a-5p significantly promoted cell proliferation, and migration and reduced apoptosis of
GECs under HG conditions. MiR-30a-5p directly targeted the 3-UTR region of Notch1. Exosome
miR-30a-5p reduced the expression levels of Notch1 and VEGF, both at mRNA and protein levels.
Furthermore, exosome miR-30a-5p inhibited HG-induced EndMT, as evidenced by increased
VE-cadherin and reduced α-SMA. In vivo studies demonstrated that exosome miR-30a-5p reduced
serum HbA1c levels and 24-hour urine protein quantification.

Conclusion:

This study provides evidence that exosome miR-30a-5p suppresses EndMT and abnormal
angiogenesis of GECs by modulating the Notch1/VEGF signaling pathway. These findings
suggest that exosome miR-30a-5p could be a potential therapeutic strategy for the treatment
of DN.

Evaluation
Authors: Randita Amandha Boy Timor , Wardhani Indrayuni Lukitra , Andriati Andriati , Wardani Nurul Kusuma , Philothra Petrina Theda , Subadi Imam , Melaniani Soenarnatalina
Published: September 2023

Background:

Knee osteoarthritis (KOA) is currently treated by regenerative therapies
that aim to inhibit arthritic degeneration. Extracorporeal shock wave therapy (ESWT) is one of the
physical regenerative approaches used for KOA management. However, little is known regarding
the impact of shock wave treatment on matrix metalloproteinase-3 (MMP-3), which is one of the
enzymes mediating cartilage degradation.

Objective:

To evaluate the effect of ESWT on MMP-3 levels and pain intensity in patients with
KOA.

Methods:

Fourteen patients diagnosed with Kellgren Lawrence, grades 2 and 3 KOA were recruited
for the study. ESWT piezo shockwave was applied once a week for six weeks. MMP-3 levels
in the blood were measured pre-test, mid-test (three weeks after therapy) and post-test (one week
after the last session) by enzyme-linked immunosorbent assay (ELISA). The perceived pain was
recorded at each session by the Wong Becker Face Scale.

Results:

The median pre-test, mid-test and post-test MMP-3 levels were 19.92 ng/mL, 15.89
ng/mL and 18.82 ng/mL, respectively, and there were significant differences between the pre-test
and mid-test, and the pre-test and post-test values (p < 0.05). The pain scores also decreased significantly
over the period of intervention.

Conclusion:

MMP-3 levels decreased significantly in KOA patients after ESWT, and the decline
was most obvious after 3 weeks of therapy. Therefore, EWST should be considered as a suitable
treatment option for KOA.

Authors: Kamaruzaman Mohd Asyran Safwan , Satari Hisam , Sokhibul Fadil Siti Aishah , Poniran Nurul Atikah , Jaafar Mohamad Hasif
Published: September 2023

Zakat institutions have observed that allocated funds for students were not being fully utilized each year. This raises questions about whether the students were not aware of the available funds or if the allocated funds were not suitable for their needs. First-timers were more likely to apply zakat for stationeries and paying for tuition fees while repeaters were more likely to pay tickets for public transports. The study's findings provide insight into the spending behavior of students who applied for zakat and can be used as a reference to justify fund allocation in universities.

Authors: Ponce Rodríguez Raúl Alberto , Ponce Rodríguez Benito Alán
Published: September 2023

Objective. We study the effect of remittances on the size and composition of public spending. Methodology. An optimization technique is used to develop a dynamic theoretical model and a simulation analysis. Results. It is demonstrated that remittances have a positive income effect on public goods, but a negative income effect and a price effect on social transfers, which explains why public goods increase, but social transfers can increase or fall due to changes in the remittances. Recommendations. The model makes recommendations for public policy design by characterizing the optimal level of public spending. Limitations. It is desirable to extend our analysis to consider electoral incentives and thus provide different explanations of how remittances might affect public spending. Originality. To the best of our knowledge, this is the first document that develops a theory to explain the effect of remittances on the size and composition of public spending. Conclusions. Remittances have a differentiated effect on public goods and social transfers depending on the income and price effects that affect the composition of public spending.

Authors: Li Wenhao , O'Hara Rebecca , Hull M Louise , Slater Helen , Sirohi Diksha , Parker Melissa A , Bidargaddi Niranjan
Published: September 2023

BACKGROUND

In the digital age, search engines and social media platforms are primary sources for health information, yet their commercial interests–focused algorithms often prioritize irrelevant content. Web-based health applications by reputable sources offer a solution to circumvent these biased algorithms. Despite this advantage, there remains a significant gap in research on the effective integration of content-ranking algorithms within these specialized health applications to ensure the delivery of personalized and relevant health information.

OBJECTIVE

This study introduces a generic methodology designed to facilitate the development and implementation of health information recommendation features within web-based health applications.

METHODS

We detail our proposed methodology, covering conceptual foundation and practical considerations through the stages of design, development, operation, review, and optimization in the software development life cycle. Using a case study, we demonstrate the practical application of the proposed methodology through the implementation of recommendation functionalities in the EndoZone platform, a platform dedicated to providing targeted health information on endometriosis.

RESULTS

Application of the proposed methodology in the EndoZone platform led to the creation of a tailored health information recommendation system known as EndoZone Informatics. Feedback from EndoZone stakeholders as well as insights from the implementation process validate the methodology’s utility in enabling advanced recommendation features in health information applications. Preliminary assessments indicate that the system successfully delivers personalized content, adeptly incorporates user feedback, and exhibits considerable flexibility in adjusting its recommendation logic. While certain project-specific design flaws were not caught in the initial stages, these issues were subsequently identified and rectified in the review and optimization stages.

CONCLUSIONS

We propose a generic methodology to guide the design and implementation of health information recommendation functionality within web-based health information applications. By harnessing user characteristics and feedback for content ranking, this methodology enables the creation of personalized recommendations that align with individual user needs within trusted health applications. The successful application of our methodology in the development of EndoZone Informatics marks a significant progress toward personalized health information delivery at scale, tailored to the specific needs of users.

Correcting non-independent and non-identically distributed errors with surface codes
Authors: Tiurev Konstantin , Derks Peter-Jan H. S. , Roffe Joschka , Eisert Jens , Reiner Jan-Michael
Published: September 2023

A common approach to studying the performance of quantum error correcting codes is to assume independent and identically distributed single-qubit errors. However, the available experimental data shows that realistic errors in modern multi-qubit devices are typically neither independent nor identical across qubits. In this work, we develop and investigate the properties of topological surface codes adapted to a known noise structure by Clifford conjugations. We show that the surface code locally tailored to non-uniform single-qubit noise in conjunction with a scalable matching decoder yields an increase in error thresholds and exponential suppression of sub-threshold failure rates when compared to the standard surface code. Furthermore, we study the behaviour of the tailored surface code under local two-qubit noise and show the role that code degeneracy plays in correcting such noise. The proposed methods do not require additional overhead in terms of the number of qubits or gates and use a standard matching decoder, hence come at no extra cost compared to the standard surface-code error correction.

Bodily-Affective Aspects of Phenomen in Malevich’s Suprematism
Authors: Khakhalova Anna A.
Published: September 2023

The study addresses some aspects of Suprematist theory of perception, allowing to investigate the structure of Suprematist phenomenon in the context of ontology, socio-political and religious-mystical works of K. Malevich. The aim of the paper is to present Malevich’s theory of perception in the framework of enactivism. Namely, the article focuses on the theory of social affordances, which today is widely used in design, game development and other everyday practices. The author refers to Malevich’s theoretical and sociopolitical essays, as well as to the commentary literature. Although Suprematism represents a well-researched tradition in art theory, the author stress the need for a follow-up study of Malevich’s theoretical essays in the contemporary context of philosophy of consciousness. The author also emphasizes the relevance of Suprematist philosophy for today’s way of thinking. For the most authentic presentation of Malevich’s ideas I use the phenomenological and hermeneutical method on a par with elements of the ecological approach in psychology and enactivism in the philosophy of consciousness. Consequently, the theory of affordances an effective and natural unification of all the aspects discussed above. The study shows the affinity of Malevich’s ideas to this theory. The author focused on the thesis of feeling as the goal of the expressive act of art. As one could see, Kazemir Malevich always emphasized the bodily-affective dimension of art, and in this sense he participated in a global cultural-historical shift in our conception of the essence of art. Since then, art has ceased to be elitist, but has instead inherited everyday practices. Thus, Malevich speaks of a new art that suits the man of the new world, the Soviet citizen. In this context, I relate the idea of affordance, which means the creation of a feeling-opportunity for subjective action (agency), to the artistic act whose goal, according to Malevich, is the creation of an emotional body-affective feeling. I defend the theory of social affordances, explaining the mechanism of social interaction, as the most adequate model for explaining Suprematism. As a result, based on the already developed concept of bodily-affective dynamics, I show how visionary and creative Malevich was, and how his ideas contribute to the development of a theory of social, emotional affordances.

Published: September 2023

Problem-solving skills are highly important in various aspects of life and professions, particularly in mathematics education. However, many students struggle to develop these skills due to a lack of understanding, critical thinking abilities, practice, and motivation. To address this, educators need to adopt teaching strategies that strengthen students' problem-solving skills. One effective approach is the scientific learning model, which emphasizes the scientific process, critical thinking, collaboration, and real-world applications. This study aims to assess the improvement of seventh-grade students' mathematical problem-solving skills using the scientific learning model. The research utilizes a descriptive quantitative approach with a two-group pretest-posttest design. The sample consists of seventh-grade students from an Islamic Junior High School, and data collection includes pretest and posttest questions. The N-gain formula is used to measure improvement. The findings indicate a significant improvement in problem-solving abilities among students who receive instruction using the scientific learning model compared to those who do not. The improvement is categorized as moderate in the experimental class, while the control class shows a lower level of improvement. Factors such as students' enthusiasm, implementation of real-life problems, and increased independence contribute to the improvement in students' problem-solving abilities. The implementation of the scientific learning model significantly enhances students' mathematical problem-solving skills. Based on the field findings, there is a need for improvement in soft skills to support meaningful learning activities.
Lyapunov Function-based Adaptive Nonlinear Controller Design for Multilevel Shunt Active Power Filter with LCL Coupling
Authors: Salimi Mahdi , Miralilu Hassan Manafi
Published: September 2023

Parameters uncertainty in the model of power electronic converters e.g.,
cascaded grid connected multilevel inverters with LCL coupling can lead
to the stability and robustness issues of closed-loop systems in a real
system. Hence, closed-loop stabilization of the power electronic
converters in a wide range of changes is a challenging task. Also, it
can result in the spoiling of THD value in a grid-connected inverter
beyond the acceptable and standard ranges. To cope with these issues, in
this paper, an adaptive nonlinear controller is developed based on the
Lyapunov stability criteria for a multilevel shunt active filter with
three cascaded H-bridges. Despite the complex model of the mentioned
system, it is shown that the designed adaptive controller can improve
the performance of the closed-loop system by estimating the uncertain
values of inductors in the LCL coupling network. The stability and
robustness of the controller are proved using the Lyapunov stability
criteria in the whole operational range of the system. The simulation
results show that the proposed controller is stable and robust in a wide
range of load current changes. Moreover, to stabilize the DC link
voltages of the grid-connected inverter, a novel approach based on the
mean minimum value of DC-link voltage errors is used which has led to
the robust and fast stabilization of these voltages. It should be noted
that all simulations have been performed by using the EMTDC/PSCAD
toolbox. Finally, a small-scale prototype has been implemented for
experimental verification of the system.

Published: September 2023

The rise and fall of the internal temperature of power transformer will
cause the moisture to change its distribution and aggregation position,
and the local high moisture content will seriously affect the electrical
strength of oil-paper insulation. Therefore, it is necessary to study
the adsorption and desorption of moisture in cellulose insulation at
different temperatures. In this paper, three oil-cellulose mixed systems
(OCS) of 105 atoms with different moisture contents were established by
molecular dynamics method, and temperature rise and temperature drop
simulations were conducted respectively. The changes of the water
molecule number (NW) in the interface domain and oil domain were
obtained. By analyzing the solvent accessible surface area (SASA) and
the microscopic scanning electron microscope (SEM) images of cellulose
insulation, the effect of temperature changes and the deterioration of
cellulose molecules on the moisture adsorption and desorption in
cellulose insulation were studied. The results show that after the
high-temperature system is reversely cooled, water molecules in the oil
domain will migrate rapidly to the cellulose domain, while the
irreversible deterioration of cellulose after high temperature leads to
the weakening of its adsorption capacity. As a result, a large amount of
water is retained at the interface. For the simulation of temperature
rise, the higher the temperature is, the more water molecules accumulate
in the oil domain and interface domain, and the stronger the desorption
effect of cellulose on moisture. Notably, NW in the interface domain is
not a simple increment trend, but an oscillatory increase and decrease
trend that decreases first and then increases. The higher the
temperature is, the more obvious the trend is. The research results have
important theoretical value for the real-time monitoring of moisture in
oil-immersed power equipment and the evaluation of its insulation
performance

The side-chain has a significant effect on the optical properties and
aggregation behaviors of the organic small molecule acceptors, which
becomes an important strategy to optimize the photovoltaic performance
of organic solar cells (OSCs). In this work, we designed and synthesized
three novel nonfused ring electron acceptors (NFREAs) OC4-4Cl-Ph,
OC4-4Cl-Th and OC4-4Cl-C8 with hexylbenzene, hexylthiophene and octyl
side chains on the π-bridge units. Compared with OC4-4Cl-Ph and
OC4-4Cl-Th, OC4-4Cl-C8 with linear alkyl side chain has more red-shift
absorption, which is conducive to obtaining higher short-circuit current
density. Additionally, the OC4-4Cl-C8 film exhibits a longer exciton
diffusion distance and the D18:OC4-4Cl-C8 blend film displays faster
hole transfer, weaker bimolecular recombination, and more efficient
exciton transport. Furthermore, the D18:OC4-4Cl-C8 blend films can form
good nano fibril-like interpenetrating networks, which can facilitate
exciton dissociation and charge transport. Finally, OC4-4Cl-C8 based
devices can generate an excellent PCE of 16.56%, which is much higher
than OC4-4Cl-Ph (12.29%) and OC4-4Cl-Th based (11.00%) ones, being the
highest PCE among the NFREA based binary devices. All in all, we have
demonstrated that side-chain engineering is an efficient way to achieve
high-performance NFREAs.

Published: September 2023

In the modern-day workplace, conflicts among team members are often observeddue to multiple reasons. Therefore, it is important to study the different aspects associatedwith conflict dynamics. For this research study, the sample was selected from organizationsenabled by information and communication technology, where employees are virtually connected. As a result, this research becomes particularly relevant in post-COVID-19 scenarios.SPSS version 23 was employed for moderation and mediation analyses using the Process Macro developed by Preacher and Hayes (version 3.3). Additionally, linear regression analysis was conducted. The statistical tests demonstrated a significant direct effect of task conflict on the outcome variables, as well as the indirect effects of moderating and mediatingvariables. The moderating variable of relationship conflict had a significant impact on bothtask conflict and team mindfulness. The direct association of task conflict was also assessedusing simple linear regression analysis in SPSS. This research explored a novel relationshipamong variables in virtual and digital organizations, where psychological contract breachessometimes also contribute to conflict dynamics. Thus, the study has investigated this phenomenon from the overarching theoretical perspective of mindfulness theory. Valuable recommendations have been provided for future researchers based on the insights derived from this research.
