Published: January 2024

The COVID-19 pandemic has gradually declined after more than 2 years of attacking Indonesia. This has led the government to relax the regional quarantine policy (PPKM) slightly. After the issuance of MENDIKBUD RISTEK Circular Letter No. 4 of 2021 concerning the implementation of face-to-face learning during the COVID-19 pandemic, learning that was originally carried out completely online is now allowed to carry out limited face-to-face learning. The purpose of this research is to find out the opinions of students, as well as to find out the process of implementing hybrid learning in social studies subjects at SMPN 3 Srengat which took place during the COVID-19 pandemic. This research uses a descriptive type quantitative approach. The results showed that hybrid learning was considered effective as evidenced by the dominant percentage of SMPN 3 Srengat students, in the implementation of hybrid learning in social studies subjects, students' understanding was still lacking because social studies is one of the contextual subjects and really needs the role of the teacher in explaining in class (face-to-face, not with online learning).

Wokół Pietryny. Umysł i zmysły w doświadczaniu krajobrazu miasta
Authors: Szkurłat Elżbieta , Adamczewska Maria 
Published: January 2024

Głównym założeniem proponowanej koncepcji zajęć jest doświadczanie krajobrazu miasta poprzez spacer w określonej części Łodzi.
Celem proponowanych zajęć jest tworzenie warunków do łączenia odbioru miejsc z wykorzystaniem zmysłów i zaangażowania umysłowego formie multisensorycznego poznania zorientowanego na odbiór krajobrazu Łodzi i identyfikowanie jego tożsamości. Na doświadczanie krajobrazu miasta składa się głównie obserwowanie, interpretowanie oraz kontemplowanie miejsc. Odbiorowi zmysłowemu towarzyszy również porównywanie, komentowanie, wartościowanie. Jednym z elementów tej koncepcji zajęć jest uwzględnienie teorii tzw. kalotropizmu, to jest naturalnej skłonności człowieka (wrodzonej potrzeby) do odczuwania, poszukiwania, kontemplowania, podążania ku pięknu i jego tworzeniu. W proponowanym spacerze kalotropizm odnosiłby się zarówno do odbioru i doświadczania krajobrazu postrzeganych miejsc, jak również tworzenia w wyobraźni nowych wizji wybranych miejsc − „ozdabiania tych miejsc wyobraźnią”. Proponowany spacer zawiera niektóre elementy tzw. flanerowania, włóczenia się, specyficznego rodzaju spacerowania po mieście.
W zaplanowanej koncepcji zajęć określone zostały zasady doświadczania krajobrazu miasta w odbiorze zmysłowym, refleksji i interpretacji zawartych m.in. w słowach–kluczach. Zaproponowana została w niej trasa spaceru, treść karty obserwacji do wpisania słów-kluczy odnoszących się do wyników obserwacji. W materiałach pomocniczych do zajęć terenowych zamieszczono najważniejsze informacje i źródła dotyczące miejsc, obiektów na zaproponowanej trasie. Materiały te wspierać mają samodzielną obserwację krajobrazu Łodzi, rozpoznawanie jego genius loci, wsłuchanie się w krajobraz dźwiękowy miasta, identyfikowanie miejsc o znamionach piękna, zrewitalizowanych, ale też miejsc zdegradowanych, nie-miejsc, tzw. miejsc straconych, brzydkich.

Published: January 2024

Pyraminx is a twisty puzzle in the shape of a tetrahedron with 4 sides. Pyraminx is played with the bottom completely flat and the front side facing the person holding the Pyraminx. The goal of the Pyraminx game is to randomize the colors, then return the scrambled colors to their original color positions by rotating the sides. This research does not discuss the most effective way of solving Pyraminx but focuses more on proving that movements in Pyraminx form group and that there is a group isomorphism from the group of Pyraminx movements to the symmetry permutation subgroup in Pyraminx. First, it is proved that movements in Pyraminx form group using 2 methods, namely direct proof in Pyraminx (Pyaminx movement group) and performing permutations in set containing numeric labels in the form of numbers 1 to 36 on Pyraminx facets by following the movements of Pyraminx ( symmetry permutation subgroup). Furthermore, it is proved that there is a group isomorphism from the Pyraminx movement group to the symmetry permutation subgroup in Pyraminx.

Published: January 2024

Keandalan merupakan karakteristik utama yang harus dijaga dalam unit pembangkitan listrik seiring dengan kenaikan konsumsi energi listrik di Indonesia. Apabila keandalan tidak dapat dijaga, maka akan dapat merusak peralatan pembangkit dan mengganggu penyaluran pasokan listrik ke beban-beban. Kegagalan pada keandalan unit pembangkitan listrik dapat disebabkan oleh kondisi arus gangguan hubung singkat. Pada penelitian ini dilakukan analisis terkait kondisi arus hubung singkat pada jaringan kelistrikan pada beban motor boiler feed pump (BFP) 4A PT PLN Nusantara Power UP Gresik. Analisis dilakukan untuk menentukan kondisi arus hubung singkat maksimum dan minimum dengan menggunakan perangkat lunak ETAP 12.6. Terdapat dua busbar yang dijadikan objek simulasi ketika mengalami gangguan, yaitu busbar 15 kV dan busbar switchgear M/C 4,16 kV. Hasil simulasi yang didapatkan besar nilai arus hubung singkat maksimum dan minimum. Nilai arus hubung singkat maksimum didapatkan dari kondisi transien berupa gangguan tiga fasa dan satu fasa ke tanah.

Vanadian–Chromian Spinels (Sludyanka Metamorphic Complex, South Baikal Area). Magnesian Spinel
Authors: Reznitsky L.Z. , Sklyarov E.V. , Barash I.G. 
Published: January 2024

Abstract
—The paper presents data on two groups of magnesian Cr–V spinel occurring as rock-forming minerals in various types of Cr–V bearing rocks of the Sludyanka metamorphic complex (South Baikal area, Siberia, Russia): (i) low-Al magnesiochromite–magnesiocoulsonite spinels and (ii) Al spinels varying from V-bearing aluminous magnesiochromite and Al–Cr coulsonite to spinel proper with minor contents of Cr and V, and with complex zoning patterns. Spinels in the Sludyanka rocks are also present as iron-magnesian accessories, among which high-Cr varieties are compositionally similar to mantle-derived spinel from igneous rocks and to inclusions in diamonds. Comparison of formation conditions for mantle spinels in igneous lithologies and spinel phases in metamorphic rocks shows that their mineral chemistry is mainly controlled by the bulk composition of the igneous and sedimentary protoliths, respectively. Detrital spinel may be a false indicator poorly applicable to paleogeodynamic reconstructions and diamond potential evaluation.

Abstract

Introduction: The absence of a comprehensive understanding of potential anaphylactic reactions to local anesthetics (LAs) and management can result in grave consequences.
Aims: To assess Latin American dentists' knowledge, preparedness, and competency in managing anaphylactic reactions to LAs.
Design: A cross-sectional study was conducted from November 2021 to February 2022.
Setting: Argentina, Brazil, Colombia, Costa Rica, Ecuador, Honduras, Mexico, Peru, Venezuela, and other Latin American countries.
Materials and Methods: Board-certified dentists answered a survey comprising 26 structured questions. Chi-square tests and logistic regression models were performed in Stata 17.0.
Interventions: None.
Results: Of 507 respondents, lidocaine was the most frequently used LA (88.1%). While 85.2% could identify dyspnea as a symptom of anaphylaxis, only 50.1% knew the correct route for epinephrine administration, and just 43.5% had epinephrine in their emergency kits. Confidence in managing anaphylactic reactions was low (9.6%). Older age was inversely related to both knowledge of anaphylaxis management and the possession of epinephrine (P=0.003 and P=0.0001, respectively).
Discussion: Our study highlights a concerning discrepancy between the practical readiness of Latin American dentists in handling anaphylaxis.
Conclusion: The study's findings underscore the need for educational interventions to improve the readiness to identify and handle anaphylactic emergencies in dental practice.

Abstract
In response to the pressing need to combat global climate change, carbon capture, utilization, and storage (CCUS) technology has gained prominence in environmental remediation. This study leverages the practicality of CCUS to develop a wet absorption process and mineral carbonation utilizing seawater-based industrial wastewater. The experiments involved the utilization of seawater and the simulation of actual flue gas conditions. The optimal conditions for NaOH production, ion separation, CO2 absorption, and mineral carbonation are determined by analyzing parameters, including flow rates, concentrations, and pH levels. The experimental results are complemented by computational studies using an Aspen Plus, which elucidates the process kinetics and predict the performance of the absorption process at the pilot-plant scale. The economic feasibility of the commercial-scale implementation of the seawater-based CO2 utilization process is also evaluated considering both the potential environmental and economic benefits. This study provided valuable insights into a sustainable and economically viable approach for CO2 utilization and NaOH production from seawater.

Abstract

Klebsiella pneumoniae has been identified as one of the most important opportunistic pathogens responsible for nosocomial infections. Antibiotic resistance and ability to form biofilms are the two main factors involved in the persistence of infections. Conventional detection methods involve culture isolation and identification followed by biofilm assay that takes 48–72 hrs. Timely detection of biofilm-forming resistant pathogens is essential to appropriately treat the infection with the right dose and combinations. The present study focusses on evaluating an RT-PCR panel using mrkD, pgaC and wcaJ genes to screen for biofilm-forming K. pneumoniae from ETA/BAL specimens. The assay accurately identified K. pneumoniae harboring samples with a limit of detection (LOD) of 1 ng/µl total RNA. Representative culture-negative-PCR-positive samples were subjected to metagenomics which identified K. pneumoniae reads in these samples confirming the specificity of RT-PCR. mrkD and pgaC acts as K. pneumoniae specific identification, whereas wcaJ act as negative marker for biofilm-forming K. pneumoniae. In addition, RT-PCR results correlated well with the phenotypic biofilm forming assay. This RT-PCR assay is the first of its kind for rapid identification of biofilm-forming K. pneumoniae. The result of this study highlights that the rapid detection of K. pneumoniae biofilms based on the RT-PCR results coupled with clinical conditions would be appropriate to treat emerging infections or to prevent re-infections in the clinical settings.

Published: January 2024

Abstract

Purposes:
To investigate efficacy and safety of cervical polypectomy under vaginoscopy in pregnant women.
Methods
The pregnant patients with cervical polyps were retrospectively included in Beijing Tiantan Hospital, Capital Medical University from April 2017 to April 2023. A vaginoscopy technique for cervical polypectomy without a speculum, cervical forceps, and anesthesia was applied for group A, and conservative management was used for group B. The rate of spontaneous abortion, preterm birth, preterm rupture of membranes (PROM), the timing and mode of delivery, and neonatal outcomes were analyzed.
Results
90 pregnant patients with cervical polyps who underwent cervical polypectomy were included into group A (n = 48) and patients without operation were assigned to group B (n = 42). At baseline, the rate of vaginal bleeding pre-operation, the length and width of the cervical polyp were higher in group A than in group B. The median interval from vaginal bleeding to polypectomy was 3.5 weeks and the median time of polypectomy was performed at gestational week 19 in group A. There was no difference on the incidence of spontaneous abortion in two groups (4.2% vs. 4.8%, p = 1.000). However, a significantly lower frequency of preterm birth (4.2% vs. 21.4%, p = .030) and PROM (18.8% vs. 45.2%, p = .025) were observed in group A than in group B. There was no difference in the timing, mode of delivery, and neonatal outcomes in both groups.
Conclusions
The cervical polypectomy under vaginoscopy reduced the risk of preterm delivery and PROM in pregnant women with symptomatic cervical polyps.

Published: January 2024

Abstract

In the quest for miniaturization across technical disciplines, microscale ceramic blocks emerge as pivotal components, with performance critically dependent on precise scales and intricate shapes. Sharp-edged ceramic microparticles, applied from micromachining to microelectronics, require innovative fabrication techniques for high-throughput production while maintaining structural complexity and mechanical integrity. This research unveils a revolutionary "one-pot microfluidic fabrication" technique, blending two innovative device fabrication strategies, "groove & tongue" and sliding assembling. This approach yields a remarkable variety of microparticles, each intricately shaped and precisely crafted, significantly surpassing traditional methods in both production speed and quality. Optimally designed sintering profiles enhance microparticles’ shape retention and structural strength. Extensive compression and scratch tests validate the superiority of microparticles, suggesting their practicability for diverse applications, such as precise micromachining, sophisticated microrobotics and delicate microsurgical tools. This advancement marks a paradigm shift in microscale manufacturing, offering a scalable solution to meet the demanding specifications of miniaturized technology components.

Published: January 2024

Abstract
Introduction:
Irritable bowel syndrome (IBS) is a common chronic functional gastrointestinal disorder. Despite the intricate and varied range of symptoms, there are now no recognized effective therapeutic methods. Mendelian randomization (MR) is a commonly employed method for repurposing existing licensed medications and identifying novel therapeutic targets. Hence, our objective was to discover new treatment targets for IBS and investigate their pathophysiological mechanisms and potential adverse consequences.
Methods
A two-sample MR analysis was conducted to determine the causal impact of druggable genes on IBS by merging data from expression quantitative trait loci (eQTLs) and genome-wide association studies (GWAS). Afterward, the colocalization analysis was conducted to identify possible druggable genes associated with the extent of treatment response in IBS patients. Furthermore, the phenome-wide MR approach was utilized to evaluate the potential detrimental impacts of pharmacogenes in treating IBS. In addition, the study conducted multi-omics integration analyses to explore potential pathogenic mechanisms of the druggable genes for IBS.
Results
56 potential druggable genes for IBS were discovered by combining IBS GWAS and druggable eQTL data. Following the completion of the colocalization investigation, a total of 8 putative druggable genes for IBS were ultimately discovered. Except for NEU1's association with the quantity of LAMP1, CEACAM6, and DPP4 proteins, further phenome-wide MR analysis revealed that the prospective druggable genes for IBS did not exhibit any potential adverse effects. Eight putative druggable genes for IBS were found to influence IBS from several different angles, including gastrointestinal metabolites, microbiota, and inflammation in the gastrointestinal tract.
Conclusions
The study employed the MR analysis to identify putative druggable genes for IBS. These discoveries not only offer a new theoretical basis for current approaches but also have the potential to facilitate the creation of more precise treatments and innovative drugs for IBS.

Abstract

During the expedition KH-23-5 with RV Hakuho Maru to the Kuril-Kamchatka (KKT) and Japan Trenches (JT) in September 2023, bottom trawls were deployed with plankton nets and yielded a high number of supra- and epibenthic benthic organisms, especially a high number of isopod crustaceans (Peracarida, Malacostraca). In total, we sampled 2,634 specimens of Isopoda from at least 14 families and the suborder Epicaridea at 28 stations. Five families occurred with more than 100 specimens, these were the Munnopsidae with the highest number of specimens (1,122 individuals), followed by Haploniscidae with 564, Macrostylidae with 430, Ischnomesidae with 245, and Desmosomatidae with 168 individuals. Station C8 yielded the highest number of individuals (488) and at station F11 only a single isopod was sampled. Our data document the efficiency of these additional plankton nets and we recommend to deploy bottom trawls with plankton nets in future more frequently.

Abstract
Aims
Water-soluble components in root exudates of C. pilosula are auto-toxic and allelopathic, severely limiting its growth. To effectively alleviate limitations to continuous cropping of C. pilosula.
Methods
C. pilosula seedlings were cultured by hydroponics and aqueous leachate were collected. The growth indexs and enzyme activity of C. pilosula seedlings were measured under the treatment of aqueous extracts of C. pilosula root exudates. Gas chromatography-mass spectrometry (GC-MS) analysis was used to qualitatively identify the chemical constituents in an aqueous solution of root secretion of C. pilosula at a concentration of 125 mg/mL.
Results
The inhibitory effects on seed germination, seedling growth, and antioxidant enzyme activity, gradually increased with the increase in concentration of the aqueous extracts of C. pilosula root exudates. The auto-toxic comprehensive effect of the aqueous extracts of root exudates of C. pilosula were strongest at 50 mL concentration and during the reproductive period, reducing SOD and POD activity, and MDA content of C. pilosula seedlings by 72.3, 71.7, and 83.3% (P < 0.05) compared to the control. Three major allelopathic components, acetic acid, hexamethyl cyclotrisiloxane, and methoxybenzene oxime were isolated and identified in the aqueous extract of root exudates of C. pilosula. Acetic acid had the highest relative content, accounting for 44.1% of all chemical components.
Conclusions
The aqueous extracts of root exudates of C. pilosula had a significant auto-toxic effect on seed germination and seedling growth of C. pilosula, with the strongest such effect during the reproductive period of C. pilosula, and low molecular weight organic acids were the main allelopathic components.
