Virtuelle Räume als Ort des Lernens oder als Zufluchtsort vor der Realität?
Authors: Gabriel Sonja
Published: October 2023

The last years have shown an increase in (online) gaming. Especially during Covid-19 restrictions many players made use of games to stay in contact with others and to socialize. Although the concept of the third place was originally meant to address only real-life spaces, there are some characteristics of third places that can be projected onto virtual spaces and especially onto Massively Multiplayer Online Games as well. Another term being related to online games are affinity spaces – defined as online spaces where socializing as well as learning and exchanging knowledge take place. These affinity spaces are often found close to popular media – and also as communities around games. Although research has linked spending time in online games with negative psychological consequences for the players for some time, newer research shows also the positive outcomes on wellbeing when spending time in virtual worlds. As far as teaching and media literacy are involved, online games and virtual worlds should be regarded as places in which learning can take place.

Published: October 2023

Abstract: When the Cua Dai bridge is built across the Thu Bon River, it causes a narrowing of the flow leading to scour, which seriously threatens the pier and endangers the structure. In order to limit the influence of scour the bridge, it is necessary to ensure that the scour under the bridge is within the allowable range. At the same time, it is necessary to take measures to limit and overcome the causes of scour. Therefore, the study and prediction of locations that are likely to cause scour are of great significance in choosing effective and versatile prevention solutions for works on this river section. Most of the scour formulas for bridge use the 1D average velocity to calculate; The calculated results are much different from the real distribution of flow velocity in the river. Therefore, the results of scour calculation often have big deviations from reality, especially when the river cross-section has no flats or curved rivers... The article focuses on researching scour at the bridge pier based on the two-dimensional horizontal velocity in front of the pier by using RIVER 2D model, built from the mathematical model of two horizontal flows and solved by the finite element method. The results of the paper show that the scour depth of pier by the one-dimensional (1D) average velocity gives much larger than when applying the two-dimensional horizontal velocity to calculate the scour.

Published: October 2023

A residential rat might harm human health because it acts as a disease reservoir. It has been many efforts to control this rate using synthetic rodenticide. Nevertheless, synthetic rodenticides broke the environment and made rats resistant. Yam (Dioscorea hispida) tube application on rat’s bite could solve the problem. This study evaluated the histology of male Wistar rats (Rattus norvegicus) fed with bite block supplemented with different yam tuber flour concertation to control residential rat populations. Five different treatments were applied with five replications. The treatments were negative control and brodifacoum 0.005% (positive control), 30%, 50%, and 70% of yam tuber flour. The results show that yam tuber supplementation caused damage to male Wistar rat stomachs, as indicated by mucosal erosion and the presence of inflammatory cells. The statistical test indicated that stomach damage significantly differed among treatments, with the severest damages caused by 50% yam tuber supplementation. It could be concluded that the rat’s bite containing yam tuber flour caused stomach damage, and the feed bite containing 70% yam tuber flour was the most effective. This result proved that yam tuber has good potential as a natural rodenticide to control residential rat populations.

Authors: Abu Hassan Shaari Helyati
Published: October 2023

In this study, a conductive film of poly (methyl methacrylate)/polyaniline (PMMA/PANi) was fabricated through a free radical copolymerization reaction using methyl methacrylate (MMA) and aniline monomers at different aniline-to-MMA ratios, namely, 1:1, 1:3, and 1:5. The PMMA/PANi copolymer films exhibited a total electromagnetic interference (EMI) shielding effectiveness (SET) of 0.45, 0.60, and 1.22 dB, respectively, which is more than twice that of the pure PMMA film (0.16 dB). The copolymer films possess the highest conductivity of 2.34 x 10−6 S/cm at the optimum value of aniline for films polymerized with a 1:3 PMMA:PANi ratio. Higher conductivity materials exhibited lower resistance and, thus, absorbed more EM energy, resulting in better EMI shielding

Published: October 2023

Background and Objectives

Gastric cancer (GC) is among the most malignant tumor types, which causes heavy healthy and economic burden to the people and societies all around the world. Establishment of an effective set of prognostic marker will benefit a lot to the treatment of GC patients clinically. Ferroptosis is a newly identified regulated cell death modality, with tight relevance with GC development. However, its application in the prognosis of GC has not been studied in detail. Deregulated messenger RNA (mRNA) and long non-coding RNA (lncRNA) expression profile in tumor can serve as novel prognostic marker for predicting the survival and cancer relapse in patients.

Methods

We downloaded ferroptosis-related gene expression microarray data, clinicopathologic information and a list of 259 ferroptosis-related genes from The Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), and Ferroptosis database, respectively. Then, correlation analysis, univariate and multivariate Cox regression analysis were used to construct a novel prognostic model for GC. Then, we validated the model in the GEO datasets. Finally, we evaluated the differences in immune microenvironment between high- and low-risk groups.

Results

We utilized the ferroptosis-related mRNA and lncRNA profile to successfully construct a prognostic model (incorporating 2 mRNAs and 15 lncRNAs) in GC. Our model, integrating diverse clinical traits and critical factors of GC, showed desirable efficacy in the prognosis of GC patients. This model also manifested effectively in validation by using external patients’ data.

Conclusions

Our study developed a novel ferroptosis-related signature to predict the prognosis of gastric cancer patients. The ferroptosis-related signature had a favorable predictive ability. This model may greatly boost the treatment of GC patients in clinical practice.

This study discusses the discourse of sexual violence in the short film Demi Nama Baik Kampus and the short film Please Be Queit to find out the representation of women as victims of sexual violence in the film. This study uses qualitative methods and Sara Mills' critical discourse. Based on its form, critical discourse analysis is divided into 3, namely the position of the subject-object and the position of the reader by selecting scenes that are considered representative. The findings of the analysis show that the position of the subject is carried out by a female character named Sinta who is a victim of sexual violence by her supervisor in the campus environment in the short film For the Good Name of the Campus. Whereas in the short film Please Be Queit played by Sarah who is considered a victim of sexual violence in the work environment. The position of the object is described as an actor that supports the subject's motion. Meanwhile, the writer positions Sarah and Sinta as parties who confirm the incident, so that the text is from the point of view that Sinta and Sarah experienced. The reader's position cannot change the discourse written by the author, because the reader cannot provide arguments to the writer, if there is no discrepancy in the content of the film's discussion.

Who’s Afraid of Electrical Stimulation? Let’s Revisit the Application of NMES at the Knee
Authors: Arhos Elanna K. , Ito Naoaki , Hunter-Giordano Airelle , Nolan Thomas P. , Snyder-Mackler Lynn , Silbernagel Karin Grävare
Published: October 2023

BACKGROUND: Restoring quadriceps strength is essential for successful rehabilitation of knee injuries, but many athletes return to their previous activity with persisting muscle weakness. Strong evidence supports using neuromuscular electrical stimulation (NMES) to improve quadriceps strength; however, there is a lack of widespread clinical implementation. We believe there is a critical need to provide clinical approaches that promote using NMES to improve patients’ quadriceps strength and ensuring clinicians provide high-value rehabilitation care.

CLINICAL QUESTION: What is best practice when using NMES to facilitate strength after injury, what are barriers to its use, and how can they be addressed?

KEY RESULTS: We discuss the low clinical implementation of NMES, perceived barriers to using NMES, and provide recommendations for setup and dosage parameters for effective use of NMES.

CLINICAL APPLICATION: We aim for this commentary, with accompanying videos, to serve as a resource for clinicians who are using commercially available NMES units in clinical practice. J Orthop Sports Phys Ther 2024;54(2):101-106. Epub 31 October 2023. doi:10.2519/jospt.2023.12028

Conformational Energy Landscapes of Amphiphiles Are Modulated by Polar Co-solutes – a Markov Analysis
Authors: Sadhu Biswajit , Clark Aurora
Published: October 2023

Microemulsions are increasingly employed within industrial processes in the pharmaceutical, food, cosmetics and petroleum industries, as well as in fundamental technologies like chemical separations. Molecular level details of microemulsion structure is a growing area of interest, as more evidence is demonstrating that intermolecular interactions between the assembled amphiphiles tune the size, shape and inter-micelle interactions within the solution. A number of features influence intermolecular interactions, including the molecular conformation of amphiphiles (through modulation of the dipole moment and molecular packing). The conformational potential energy landscape (PEL) for amphiphiles has a topology that is dictated not only by intramolecular degrees of freedom and interactions (e.g., internal hydrogen bonds) but also by how different conformations are influenced by direct solvent-solute interactions. Atomistic molecular simulations can sample the conformational ensemble, yet when monomeric units have high degrees of freedom they generate a huge amount of high-dimensional complex data. Under these circumstances, Markov state models (MSMs) are an as yet under-utilized tool to analyze simulation trajectories and provide a way to understand the conformational free energy landscape and its dependence upon solution conditions. Here, polar solute...amphiphile interactions are hypothesized to collectively control the amphiphile conformational distribution and modulate the underlying PEL. A workflow is developed for Markov state modelling that investigates the large pool of conformations that arise from the breadth of amphiphiles present in MD simulation; the MSM is used to explain the important changes to the topology of the PEL that results from solute-solvent interactions.

Nuclear expression of protein kinase CK2α is reportedly elevated in human carcinomas, but mechanisms underlying its variable localization in cells are poorly understood. This study demonstrates a functional connection between nuclear CK2 and gene expression in relation to cell proliferation. Growth stimulation of quiescent human normal fibroblasts and phospho-proteomic analysis identified a pool of CK2α that is highly phosphorylated at serine 7. Phosphorylated CK2α translocates into the nucleus, and this phosphorylation appears essential for nuclear localization and catalytic activity. Protein signatures associated with nuclear CK2 complexes reveal enrichment of apparently unique transcription factors and chromatin remodelers during progression through the G1phase of the cell cycle. Chromatin immunoprecipitation-sequencing profiling demonstrated recruitment of CK2α to active gene loci, more abundantly in late G1phase than in early G1, notably at transcriptional start sites of core histone genes, growth stimulus-associated genes, and ribosomal RNAs. Our findings reveal that nuclear CK2α complexes may be essential to facilitate progression of the cell cycle, by activating histone genes and triggering ribosomal biogenesis, specified in association with nuclear and nucleolar transcriptional regulators.
Food safety knowledge, attitudes, and practices among online food delivery
services during COVID-19 pandemic in Jabodetabek area, Indonesia
Authors: Mutaqin M.Z. , Dewanti-Hariyadi R. , Nurtama B.
Published: October 2023

The coronavirus 2 (SARS-CoV-2) in some countries including Indonesia, has changed
consumer behavior in accessing their food from direct buying from food services (i.e.
food groceries, restaurants, cafes) to online buying by using an application from their
smartphone. By using online food delivery services, knowledge, attitude, and practices of
food handlers (FH) and food delivery workers (FDW) contributed to food safety. This
study aimed to predict the food safety practices of FH and FDW by conducting a survey
on their knowledge and attitude on food safety in Jakarta-Bogor-Depok-TangerangBekasi (Jabodetabek) area, Indonesia. The FDW were from Gofood, Grabfood,
Shopeefood, and Kulina. The questionnaire was distributed via social media, ecommerce sites, and messenger applications to 675 respondents. The survey contained
36 questions and the data were analyzed by using the partial least squares structural
equation modeling (PLS-SEM) technique. This study revealed that knowledge (β = 0.311
for FH; β = 0.136 for FDW; p < 0.05) and attitude (β = 0.417 for FH; β = 0.342 for
FDW; p < 0.05) were positively correlated to good food safety practices. The study also
indicated that attitude was the main variable in predicting the practices of FH and FDW.
Overall, the structural model for FH has a better prediction (R² = 0.374) than that for
FDW (R² = 0.165). There were gaps in food safety practices between FH and FDW that
could contribute to achieving safe foods. Comprehensive knowledge through food safety
campaigns, food safety training, and food safety culture for FH and especially FDW
could be a strategy to strengthen food safety.

Published: October 2023

Different cooking methods would produce different product characteristics. The aim of
this study was to identify product characteristics (sensory analysis, texture, color, yield,
and proximate analysis), amino acid profile, and fatty acid profile of cooked milkfish.
Milkfish were boiled (18 mins, 100°C), steamed (30 mins, 100°C), and pressure steamed
(120 mins, 121°C with a pressure of 1 atm). Based on the sensory value, the most
preferred milkfish by the panelists was pressure steamed milkfish. Pressure steamed
milkfish had the highest a* and b* values and produced the hardest texture. The highest
yield was obtained from steaming. The proximate composition showed that boiled
milkfish had the highest moisture, ash, protein, and fat content. Different cooking methods
had different effects on amino acids and fatty acids because cooking time plays a role in
determining changes in the amount of amino acids and fatty acids. Glutamic acid, aspartic
acid, lysine, and leucine were the dominant amino acids. The dominant fatty acid profiles
were palmitic acid, oleic acid, docosahexaenoic acid (DHA), and linoleic acid. Pressure
steaming was the process that took the longest time, so that the proximate and amino acid
content in it was lower than boiled and steamed, which had a shorter cooking time.
However, pressure steamed cooking resulted in the most preferred product by the
panelists.

Most of the physicians (95.9%) and veterinarians (71.5%) had not received training on One Health; significantly more veterinarians had received training (P < 0.001). Most of the veterinarians (73.3%) and a few physicians (35.1%) had applied One Health in their work (P < 0.001). Although participants mentioned other disciplines related to One Health, they had not been involved in any cooperative or collaborative work relating to these disciplines. Conclusion: The application of One Health principles by the physicians and veterinarians was limited, and few of them had collaborated with other disciplines during their practice. Joint training and further professional and educational integration are needed in Türkiye to support the implementation of One Health.

The purpose of this study was to determine the simultaneous and partial relationship between self-control and intensity of social media usage with sexual behavior in 110 adolescents. (103 girl and 7 men of SMK Class XI Accounting aged 16-18 years).  This research is a correlational quantitative study, using parametric analysis methods with multiple regression analysis techniques. The instruments used in this study are sexual behavior scale, self-control scale, and social media usage intensity scale. The results study show a significant directional relationship, partially self-control and sexual behavior show a significant negative relationship as well as the intensity of social media use and sexual behavior show an insignificant positive relationship. With this it can be concluded that high self-control and low intensity of social media use will lead to low sexual behavior, otherwise low self-control and high social media use lead to high sexual behavior. Sexual behavior is one of the problems that afflicts most adolescents in Indonesia, this behavior is related to genitals or intimate relationships aimed at attracting the attention of the opposite sex. Many factors affect adolescents both from internal factors, namely self-control and external factors, namely the intensity of social media use.

Clutter Rejection for FM Ranging Airborne Radar
Authors: Yoon Ji Hwan , Kim Yongmin
Published: October 2023

In airborne radar, it is important to reject clutter signals to detect targets of interest. High pulse repetition frequency (HPRF) waveform provides robust detection performance in a clutter environment by separating clutter signals from the target echo signals in a Doppler frequency domain, but it suffers from range ambiguity. The range ambiguity in HPRF can be resolved by frequency modulation (FM) ranging. However, the Doppler frequencies of both the clutter and target echo signals change linearly with the range due to changes in the carrier frequency in FM ranging. In such a case, the target echo signal can be rejected by a conventional clutter rejection frequency even if it is not masked by a clutter signal. This paper proposes an optimum clutter rejection frequency for FM ranging airborne radar by considering the Doppler frequency spread in FM ranging. The optimum clutter rejection frequency is derived by calculating the maximum Doppler frequency of the spread clutter signal caused by FM ranging. The simulation and flight test results verify that the proposed clutter rejection frequency is the optimum value that can improve the detection capability of FM ranging airborne radar.
Monitoring and Automation System for Bird Feeding and Drinking Based on Internet of Things Using ESP32
Authors: Pradisthi Allieffa Salsabilla , Aryanto Joko
Published: October 2023

Birds are vertebrate animals characterized by feathers and wings. Their melodious sounds and colorful plumage make them a popular choice for bird breeders, which presents a promising business opportunity. Manual feeding and drinking requires farmers to feed and drink every day, which often results in delayed feeding and drinking or inconsistent dosing, causing birds to become susceptible to disease and death. Therefore, this study is intended to create an automated system for monitoring feed and drink at predetermined times utilizing the Internet of Things (IoT) concept. The system's schedule can be remotely accessed and monitored through a website, and it operates in real-time without requiring manual intervention. This allows farmers to monitor and provide birds with food and water even from a distance. The Internet of Things (IoT) system utilized in this research employs an ESP32 microcontroller as the primary controller, which connects to a Wi-Fi network. It features a servo motor designed to refill bird feeders and drinkers. Further, a mini pump is used to replenish water in the drinker based on the owner's predetermined schedule set via the application. The research concludes that the tool functions based on the input time on the website. The system sends notifications to the breeder's smartphone regarding successful feeding and drinking, with an error rate of less than 20% in system testing and over 80% accuracy in system functioning. The outcome is in the form of a tool dispensing feed and drink daily, in accordance with the breeder's specified hours
