Published: October 2023

Background
Persistent menstrual disorders are relatively common in patients with SLE, including hypermenorrhea, oligomenorrhea, amenorrhea, and temporary persistent amenorrhea. These failures are due to autoimmunity and medications, especially immunosuppressive agents.
Materials and methods
This cross-sectional pilot study was performed on all the SLE patients referred to our medical department who were eligible for participation. Venous blood samples were taken for FSH, LH, and anti-mullerian hormone measurement.
Results
50 patients divided into two groups, 16–35 (46%) and 51 − 35 (54%), were included in the study. Among the patients, 82% used hydroxychloroquine, 80% prednisolone, 20% Azathioprine and 6% methotrexate. Dysmenorrhea was more common in the age group of 51 − 35 years, but there was no statistically significant difference between the two groups. The frequency of the people using prednisolone was remarkably more than non-users (94.7% vs. 5.3%), with a significant relationship between the two groups; However, there was no significant difference between patients with polymenorrhagia and menorrhagia. Additionally, menstrual disorders were not significant in patients who received hydroxychloroquine and azathioprine and those who received no medications. Furthermore, the frequency distribution of the mentioned menstrual disorders was investigated according to the SLEDAI index. The average FSH, LH, and anti-mullerian hormone values had no statistical difference between the mild, moderate, and severe flare groups.
Conclusion
In conclusion, menstrual cycle disorders with dysmenorrhea dominant are probably related to the drugs used, especially prednisolone, by patients with SLE.

Published: October 2023

The cell-derived vesicles (CDVs) obtained using a proprietary extrusion process are the foundation of BioDrone™ platform technology. With superior productivity and versatility, this technology has garnered increasing attention in broad applications, particularly as a drug delivery vehicle. Previously, we showed that CDVs exhibited varying levels of expression for tetraspanin and organelle membrane markers while revealing no discernible differences in physical characteristics compared to naturally produced extracellular vesicles (EVs). To further understand and utilize the therapeutic potentials of CDVs, a more comprehensive study of membrane protein profiles is necessary. In addition, it is crucial to validate that the CDVs produced from extrusion are indeed intact lipid vesicles rather than other impurities. Here, we produced multiple batches of CDVs and EVs from HEK293 cells. CDVs and EVs were subjected to the same purification processes for subsequent proteome and particle analyses. The proteome analyses revealed unique proteome signatures between CDVs, EVs, and parental cells. Extensive proteome analyses identified the nine most prominent membrane markers that are abundant in CDVs compared to cells and EVs. Subsequent western blotting and nanoparticle flow cytometry analyses confirmed that CD63, lysosome-associated membrane glycoprotein 1 (LAMP1), and nicastrin (NCSTN) are highly enriched in CDVs, whereas CD81, CD9, and prostaglandin F2 receptor negative regulator (PTGFRN) are more abundant in EVs. This highlights the unique membrane composition and marker signature of CDVs that are distinct from EVs. Lastly, we demonstrated that more than 90% of the CDVs are genuine lipid vesicles by combining two different classes of vesicle labeling dyes and detergents to disrupt lipid membranes. This indicates that our proprietary extrusion technology is highly compatible with other well-characterized EV production methods. The robust CDV markers identified in this study will also facilitate the engineering of CDVs to achieve enhanced therapeutic effects or tissue-selective cargo delivery.

Published: October 2023

Carrageenan is a natural polymer extracted from the Red-Seaweeds that is important for the food and pharmaceutical industries. It is crucial to comprehend how the ion exchange affects the rheological properties of Iota carrageenan polymer, particular potential for gelation, which has several applications in the food and pharmaceutical industries. The current study focuses on analyzing the rheological changes brought on by the exchange of potassium ions with calcium ions in Iota carrageenan. Due to their distinct associations with the anion component, monovalent and divalent cations both have a varied impact on the gelation property of carrageenan.
Medienkompetenz und Handlungstheorie
Authors: Tulodziecki Gerhard
Published: October 2023

Medienkompetenz wird häufig als spezifische – auf Medien bezogene – Ausprägung von kommunikativer Kompetenz verstanden. Dabei ergibt sich ein enger Bezug zum Handeln, weil soziales Handeln der Kommunikation bedarf und sich in Interaktionen realisiert. Eine solche Sichtweise hat dazu geführt, dass Handeln manches Mal nur aus kommunikationstheoretischer oder soziologischer Sicht gedeutet wird und so Verkürzungen aus pädagogisch-handlungstheoretischer Sicht entstehen. Dies gilt z. B. für den sprachphilosophisch-gesellschaftskritischen Ansatz zur kommunikativen Kompetenz von Jürgen Habermas, aber auch für dessen Weiterentwicklung und die medienpädagogischen Überlegungen von Dieter Baacke. Bis heute weisen viele Diskussionen und Entwürfe zum Begriff der Medienkompetenz oder zu „Kompetenzen in der digitalen Welt“ deutliche Schwächen und Desiderata auf. Solche Schwächen und Desiderata werden im vorliegenden Beitrag offengelegt. Die Überlegungen münden in die Zusammenstellung wichtiger Merkmale für eine Handlungstheorie ein, die zu einer besseren Fundierung medienpädagogischer Konzepte beitragen kann.

Entstehungskontext und forschungspraktischer Hintergrund des Beitrags ist das Projekt „Digitales Deutschland“ (DigiD). Das Forschungsverbundprojekt exploriert und systematisiert jene Medien- und Digitalkompetenzen der Bevölkerung in Deutschland, der es bedarf, angesichts des digitalen Wandels gesellschaftlich handlungsfähig zu sein. Die nachfolgenden Ausführungen bündeln erstens den Stand der Auseinandersetzung hinsichtlich der je spezifischen Anforderungen und Kompetenzausprägungen, die sich für Kinder und Jugendliche, Erwachsene und Menschen im höheren Lebensalter stellen und sie skizzieren vor diesem Hintergrund zweitens konzeptionelle Ansatzpunkte für ein weiterführende theoretische und praktische Auseinandersetzung.
Medienkompetenzförderung als Auftrag der öffentlichen Erwachsenenbildung
Authors: Hellriegel Jan , Rohs Matthias
Published: October 2023

Der Beitrag thematisiert die Verantwortung der öffentlichen Erwachsenenbildung in Deutschland, die Teilnehmenden zu einer selbstbestimmten Teilhabe in einer digitalisierten Gesellschaft zu befähigen. Die Förderung der dafür notwendigen Medienkompetenz im Rahmen von Weiterbildungsangeboten wird anhand von Kompetenzmodellen sowie aktueller Forschungsbefunde diskutiert. Aufgrund einer oftmals dominierenden funktionalen und instrumentellen Sichtweise auf Medienkompetenz, die zumeist im Zusammenhang mit einer ökonomischen Verwertbarkeit steht, plädiert der Beitrag für eine verstärkt kritisch-reflexive Auseinandersetzung mit den gesellschaftlichen Folgen der Digitalisierung und sieht in diesem Zusammenhang den Bedarf für eine bessere Finanzierung der öffentlichen Erwachsenenbildung und einer systematischen medienpädagogischen Aus- und Weiterbildung des Personals.
Digitale Kompetenzen und präfigurative Kommunikationskulturen
Authors: Lang Susanne
Published: October 2023

Im Beitrag wird auf das Konzept pluraler lebensweltbezogener Kulturen der Digitalität (vgl. Stalder 2016) und auf die Konzeptualisierung von Digitalisierung, als einer „Erweiterung von Welt“ (INM 1996) und nicht einer „Verdoppelung der Welt in Datenform“ (Nassehi 2019) referiert. Lebenswelt- und handlungsorientierte (vgl. Thiersch 2016; Baacke 1996) sowie medien- und kulturwissenschaftliche Perspektiven werden in Bezug auf die Eigenschaften der Kultur der Digitalität im Anschluss an Felix Stalder und seiner Analyse ihrer Formen und ihrer Bedeutung für reflexive informelle Bildungsprozesse von jungen Menschen in der globalisierten Netzwerkgesellschaft (vgl. Castells 2017) beispielshaft rekonstruiert. Dabei wird dem Postulat von Dieter Wiedemann gefolgt, dass sich Medienbildung im Zusammenhang mit neuen Kommunikationstechnologien „primär auf die Kultur der Inhalte“ und eher darüber „vermittelt, sekundär auf die Vermittlungsformen von Inhalten“ orientieren solle (vgl. Wiedemann 2001, S. 29).In Abgrenzung zu einem rein technizistischen Verständnis wird Digitalität weiterhin im Anschluss an Jörg Noller „als Form virtueller Realität im Sinne der Erweiterung unserer Freiheit“ (Noller 2022) aufgefasst. Herausgearbeitet werden epochaltypische Bedarfe an Digitalkompetenzen, die sich vor dem Hintergrund der skizzierten kulturellen Handlungsräume von Kindern und Jugendlichen in der außerschulischen und politischen Medienbildung als Bildungsherausforderungen zeigen.

Isolation and Characterisation of Culturable Thermophilic Cyanobacteria from Perak Hot Springs and their Plant Growth Promoting Properties Effects on Rice Seedlings (Oryza sativa L.)
Authors: Clement Kiing Fook Wong  , Tzu Yee Chong  , Ji Tan  , Wey Lim Wong
Published: October 2023

Malaysia is home to a number of hot springs that are rich in microbial diversity including the photosynthetic cyanobacteria. Although this microbial community has been characterised based on metagenomics approach, the culturable thermophilic isolates have not been isolated and characterised extensively. Compared to the mesophiles, information on plant growth promoting (PGP) properties of these thermophiles remain largely untapped. As the amount of arable land for microbial bioprospecting is decreasing due to extensive human activities, the search for alternative source for microbial strains with PGP properties is important for the development of potential biofertilizers. This study sought to isolate and characterise culturable cyanobacteria strains from two local hot springs – Sungai Klah (SK) and Lubuk Timah (LT) located in Perak using morphological and molecular methods. The IAA production from the axenic cultures were measured. The PGP properties were also measured by priming the rice seeds with cyanobacterial water extracts. A total of six strains were isolated from both hot springs. Strains LTM and LTW from LT were identified as Leptolyngbya sp. whereas strains SEM, SEH, STH and STM were identified as Thermosynechococcus elongatus. All six strains produced IAA ranged from 670.10 pg/ ?L to 2010 pg/?L. The water extracts were found to increase the seed amylase activity of the rice seeds from 5th day of germination (DAG) to 10th DAG. In general, the IAA production and increased seed amylase activity might have contributed in enhancing the longest root length, shoot length and root-to-shoot (RS) ratio. To conclude, the thermophilic cyanobacteria from hot springs can be further exploited as a novel source of PGP microbes for the development of biofertilisers.
Optimising Wastewater Treatment: Acinetobacter sp. IrC1 As a Potential Multi-Resistant Bacterium for Copper Accumulation and Dyes Decolourisation
Authors: Wahyu Irawati  , Triwibowo Yuwono  , Reinhard Pinontoan  , Valentine Lindarto
Published: October 2023

Improper disposal of waste containing copper and dye is an environmental issue that must be resolved immediately due to its harmful, non-degradable and toxic properties. Bioremediation efficiency can improve by cultivating copper and dye multi-resistant bacteria to remove various pollutant types simultaneously. This study aims at establishing the multi-resistance of Acinetobacter sp. IrC1 to copper and dyes. The effects of copper concentration on growth were determined using a spectrophotometer, while accumulation was analysed using an atomic absorption spectrophotometer. Bacteria-mediated dye decolourisation dyes were observed based on clear zone formation around bacterial colonies, while decolourisation percentage was calculated using a spectrophotometer. Results demonstrate that Acinetobacter sp. IrC1 resisted up to 8 mM CuSO4 and accumulated up to 292.93 mg/g dry weight of copper cells. Acinetobacter sp. IrC1 isolates were also resistant to 500 ppm Methylene Blue, Malachite Green, Congo Red, Mordant Orange, Reactive Black, Direct Yellow, Reactive Orange, Remazol, Wantex Red and Wantex Yellow dye, successfully removing up to 68.35% and 79.50% Methylene Blue and Basic Fuchsine in a medium containing 3 mM CuSO4, respectively. Further investigations are required to analyse the genetic composition of multi-resistant bacteria to optimise the effectiveness of indigenous bacterial isolates as bioremediation agents.
Analisis Adopsi Sistem ERP dalam Mengoptimasi Industri Pangan Menggunakan SEM dan Model UTAUT2
Authors: Panduwiyasa Haryasena , Yahya Rachdian Habi
Published: October 2023

In the era of Society 5.0 and the post-COVID-19 recession, entrepreneurs experienced digital disruption and economic instability, especially in the food industry sector. The low awareness of entrepreneurs in adopting technology and information systems, as well as their doubts about the high cost and time that needs to be allocated, are also reasons why the process of adopting technology and information systems is increasingly difficult to realize. To overcome costs and a relatively long development process, one of the efforts that companies can make is to adopt an open-source Enterprise Resource Planning (ERP) system that is useful for supporting resource management and decision-making. The purpose of this research is to prove how the adoption of ERP systems can support business digitalization processes and can produce industrial systems that are agile, effective and efficient. A series of analyzes were carried out using a survey aimed at 292 food industry business actors who had been digitalized by ERP, to prove the influence of behavioural factors on ERP usage using the UTAUT2 model, with the variables tested including performance expectations (PE), effort expectations (EE), price values (PV), facility conditions (FC), habits (HT), and behavioural intention (BI) toward the use behaviour of ERP (UB) in the food industry sector in Central Java, Indonesia.
Towards non-invertible anomalies from generalized Ising models
Authors: Liu Shang , Ji Wenjie
Published: October 2023

We present a general approach to the bulk-boundary correspondence of noninvertible topological phases, including both topological and fracton orders. This is achieved by a novel bulk construction protocol where solvable (d+1)(d+1)-dimensional bulk models with noninvertible topology are constructed from the so-called generalized Ising (GI) models in dd dimensions. The GI models can then terminate on the boundaries of the bulk models. The construction generates abundant examples, including not only prototype ones such as \mathbb{Z}_2ℤ2 toric code models in any dimensions no less than two, and the X-cube fracton model, but also more diverse ones such as the \mathbb{Z}_2x \mathbb{Z}_2ℤ2xℤ2 topological order, the 4d \mathbb{Z}_2ℤ2 topological order with pure-loop excitations, etc. The boundary of the solvable model is potentially anomalous and corresponds to precisely only sectors of the GI model that host certain total symmetry charges and/or satisfy certain boundary conditions. We derive a concrete condition for such bulk-boundary correspondence. The condition is violated only when the bulk model is either trivial or fracton ordered. A generalized notion of Kramers-Wannier duality plays an important role in the construction. Also, utilizing the duality, we find an example where a single anomalous theory can be realized on the boundaries of two distinct bulk fracton models, a phenomenon not expected in the case of topological orders. More generally, topological orders may also be generated starting with lattice models beyond the GI models, such as those with symmetry protected topological orders, through a variant bulk construction, which we provide in an appendix.

Refugiados LGBTQIA+ no Brasil: A proteção dos direitos da personalidade e o enquadramento às diretrizes internacionais enquanto grupos sociais
Authors: Ribeiro Daniela Menengoti Gonçalves , De Andrade Flavia Kriki
Published: October 2023

No presente artigo aborda-se a possibilidade de reconhecimento de pessoas LGBTQIA+ serem reconhecidas como refugiadas no Brasil. Tem-se como objetivo identificar se o país tem seguido as diretrizes internacionais ao analisar os pedidos. Para tanto, em um primeiro momento passa-se pela evolução do instituto do refúgio, com foco especialmente nos motivos que ensejam a justificativa da solicitação, bem como a proteção dos direitos da personalidade dos refugiados. Posteriormente, verifica-se como tal instituto foi recepcionado no país. Por fim, busca-se informações sobre como o país tem analisado os pedidos. A metodologia de abordagem utilizada foi a hipotético-dedutiva, tendo em vista que o trabalho parte da ideia principal de que a comunidade LGBTQIA+ quando precisa migrar para garantir a própria vida é acolhida pela comunidade internacional como refugiados devido ao pertencimento a grupo social. Assim, busca-se analisar se essa premissa é verídica e, não sendo, quais as razões. Para tanto, utilizou-se pesquisa documental e bibliográfica. Como resultado verificou-se que uma pequena parte dos países aceitam LGBTQIA+ como refugiados. Sobre o Brasil, o país adota a prática de aceitar todas as pessoas, sem distinção quanto a grupo social, seguindo, portanto, as orientações internacionais. Desde 2016, no entanto, a plataforma que disponibiliza dados sobre as decisões de deferimentos ou indeferimentos de refúgio apenas solicita informações de pedidos com fundamento em pertencimento a grupo social, mas sem a identificação se o pedido é realizado por pessoas LGBTQIA+.
Os direitos da população LGBTI+ no parlamento: Um diálogo entre o pluralismo de valores e o reconhecimento
Authors: Dyniewicz Letícia Ribeiro , Castro Carolina Soares Castelliano Lucena de
Published: October 2023

Esse artigo tem como propósito discutir de que forma as políticas democráticas desenvolvidas no parlamento brasileiro, em relação à população LGBTI+, de fato possibilitam sua participação paritária no dissenso democrático institucional. O tema é discutido a partir das teorias de Chantal Mouffe e Nancy Fraser, havendo a utilização de projetos de lei em trâmite na Câmara dos Deputados para demonstrar o pluralismo de valores e dissensos aparentemente irreconciliáveis referente ao reconhecimento de direitos das pessoas LGBTI+. Assim, em primeiro lugar, mobiliza-se a teoria de Mouffe para demonstrar o quanto o conflito é um elemento essencial da democracia. Em um segundo momento, a análise segue com a teoria de Fraser, que contribui para evidenciar os obstáculos que impedem a efetiva paridade de participação da população LGBTI+ no espaço do parlamento e possíveis estratégias de superação desse quadro. As diferentes concepções de reconhecimento presente em cada uma das teorias indicam que a visão do diferente enquanto adversário, e não um inimigo a ser eliminado do jogo democrático, perpassa por questões de status social e acesso a recursos materiais.
UAV-based approach for municipal solid waste landfill monitoring and water ponding issue detection using sensor fusion
Authors: Hassan Syed Zohaib , Sun Peng , Gokgoz Mert , Chen Jiannan , Reinhart Debra R. , Gustitus-Graham Sarah
Published: October 2023

Municipal solid waste (MSW) landfills need regular monitoring to ensure proper operations and meet environmental protection requirements. One requirement is to monitor landfill gas emissions from the landfill cover while another requirement is to monitor the potential settlement and damage to MSW landfill covers. Current surveying methods on a landfill cover are time- and labor-intensive and have limited spatial coverage. Landfill operators and researchers have developed unmanned aerial vehicle (UAV)-based monitoring over recent years; however, UAV-based automatic detection of water ponding in landfills has not been studied. Hence, this study proposes a UAV-based approach to monitor landfills and detect water ponding issues on covers by using multimodal sensor fusion. Data acquired from sensors mounted on a UAV were combined, leading to the creation of a ponding index (PI). This index was used to detect potential ponding sites or areas of topographical depression. The proposed approach has been applied in a case study of a closed MSW landfill before and after Hurricane Ian. A comparison between the generated PI map and a manual survey revealed a satisfactory performance with an IoU score of 70.74%. Hence, the utilization of UAV-based data fusing and the developed PI offers efficient identification of potential ponding areas.

Published: October 2023

The discharge of synthetic dyes into the environment poses a significant threat to both human health and the ecosystem, necessitating the treatment of contaminated water. To generate free radicals for the elimination of Direct Blue 71 (DB71) dye from aqueous solutions, periodate (PI) and chlorine (Cl2) have been employed. In this study, separate activation of PI and Cl2 was achieved using ultraviolet (UV) light. The impact of various operational parameters was investigated, resulting in the complete degradation of the dye within 12 min. The presence of ferrous and copper ions had a minor enhancing effect on the degradation rate in both systems. Scavenging experiments confirmed that HO• and IO3• were the primary agents responsible for DB71 degradation in the UV/PI system, while reactive chlorine radicals played a dominant role in the UV/Cl2 process. In terms of mineralization, application for real wastewater and energy efficiency, the UV/PI system exhibited slightly superior performance compared to the UV/Cl2 system.

Pemodelan produk Variable Annuity di industri asuransi jiwa
Authors: Wicaksono Agung
Published: October 2023

Secara umum, bisnis asuransi jiwa terbagi menjadi 3 lini bisnis yaitu asuransi jiwa, asuransi kesehatan, dan anuitas. Adapun yang akan dibahas lebih lanjut pada makalah ini adalah anuitas. Dilihat dari tingkat hasil investasinya anuitas dapat dibagi menjadi dua yaitu Certain Annuity (Anuitas Pasti) dan Variable Annuity (Anuitas Variabel). Menurut Kellison (2009:73), anuitas merupakan rangkaian pembayaran secara berkala dalam waktu tertentu, misalnya tahunan atau bulanan. Selain itu, anuitas juga bisa disebut sebagai program asuransi jiwa yang bertujuan memberikan kepastian adanya kesinambungan pendapatan bagi tertanggung/peserta ketika menjalani masa purna bhakti beserta keluarganya apabila tertanggung/peserta meninggal dunia. Besar manfaatnya umumnya sebesar nominal tertentu atau dihitung berdasarkan alokasi premi sekaligus, dan manfaatnya  dibayarkan secara berkala.Pada makalah ini akan dibahas mengenai variable annuity. Menurut Runhuan Feng (2012:3), variable annuity merupakan anuitas yang menawarkan profit sharing dari dana investasi. Biaya-biaya yang timbul pada variable annuity tergantung pada subaccount pilihan pemegang polis. Setiap subaccount diinvestasikan dalam metode tertentu dengan tujuan investasi yang berbeda. Untuk melindungi investor dari risiko kerugian, perusahaan asuransi juga menjual produk yang bergaransi, yaitu Guaranteed Minimum Maturity Beneﬁt (GMMB), Guaranteed Minimum Death Beneﬁt (GMDB), dan Guaranteed Minimum Accumulation Beneﬁt (GMAB).Produk variable annuity diharapkan menjawab kebutuhan dari konsumen akan adanya kesinambungan penghasilan saat memasuki usia pensiun. Selain itu variable annuity juga diharapkan menjawab keresahan dari perusahaan asuransi jiwa akan besarnya risiko produk Certain Annuity.
