Published: March 2023

Background: Little is known about the adverse events (AEs) associated with coronavirus disease 2019 (COVID-19) vaccination in patients with type 2 diabetes mellitus (T2DM).Methods: This study used vaccine AE reporting system data to investigate severe AEs among vaccinated patients with T2DM. A natural language processing algorithm was applied to identify people with and without diabetes. After 1:3 matching, we collected data for 6,829 patients with T2DM and 20,487 healthy controls. Multiple logistic regression analysis was used to calculate the odds ratio for severe AEs.Results: After COVID-19 vaccination, patients with T2DM were more likely to experience eight severe AEs than controls: cerebral venous sinus thrombosis, encephalitis myelitis encephalomyelitis, Bell’s palsy, lymphadenopathy, ischemic stroke, deep vein thrombosis (DVT), thrombocytopenia (TP), and pulmonary embolism (PE). Moreover, patients with T2DM vaccinated with BNT162b2 and mRNA-1273 were more vulnerable to DVT and TP than those vaccinated with JNJ-78436735. Among patients with T2DM administered mRNA vaccines, mRNA-1273 was safer than BNT162b2 in terms of the risk of DVT and PE.Conclusion: Careful monitoring of severe AEs in patients with T2DM may be necessary, especially for those related to thrombotic events and neurological dysfunctions after COVID-19 vaccination.
Role of SUMO-Specific Protease 2 in Leptin-Induced Fatty Acid Metabolism in White Adipocytes
Authors: Kim Praise Chanmee , Lee Ji Seon , Chung Sung Soo , Park Kyong Soo
Published: March 2023

Background: Leptin is a 16-kDa fat-derived hormone with a primary role in controlling adipose tissue levels. Leptin increases fatty acid oxidation (FAO) acutely through adenosine monophosphate-activated protein kinase (AMPK) and on delay through the SUMO-specific protease 2 (SENP2)–peroxisome proliferator-activated receptor δ/γ (PPARδ/γ) pathway in skeletal muscle. Leptin also directly increases FAO and decreases lipogenesis in adipocytes; however, the mechanism behind these effects remains unknown. Here, we investigated the role of SENP2 in the regulation of fatty acid metabolism by leptin in adipocytes and white adipose tissues.Methods: The effects of leptin mediated by SENP2 on fatty acid metabolism were tested by siRNA-mediated knockdown in 3T3-L1 adipocytes. The role of SENP2 was confirmed in vivo using adipocyte-specific Senp2 knockout (Senp2-aKO) mice. We revealed the molecular mechanism involved in the leptin-induced transcriptional regulation of carnitine palmitoyl transferase 1b (Cpt1b) and long-chain acyl-coenzyme A synthetase 1 (Acsl1) using transfection/reporter assays and chromatin immunoprecipitation.Results: SENP2 mediated the increased expression of FAO-associated enzymes, CPT1b and ACSL1, which peaked 24 hours after leptin treatment in adipocytes. In contrast, leptin stimulated FAO through AMPK during the initial several hours after treatment. In white adipose tissues, FAO and mRNA levels of Cpt1b and Acsl1 were increased by 2-fold 24 hours after leptin injection in control mice but not in Senp2-aKO mice. Leptin increased PPARα binding to the Cpt1b and Acsl1 promoters in adipocytes through SENP2.Conclusion: These results suggest that the SENP2-PPARα pathway plays an important role in leptin-induced FAO in white adipocytes.
Hyperglycemia-Suppressed SMARCA5 Disrupts Transcriptional Homeostasis to Facilitate Endothelial Dysfunction in Diabetes
Authors: Wang Ju , Zhou Hui , Shao Jinhua , Zhang Shu , Jin Jing
Published: March 2023

Background: Dysfunction of vascular endothelial cells (ECs) plays a central role in the pathogenesis of cardiovascular complications in diabetes. SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily A member 5 (SMARCA5) is a key regulator of chromatin structure and DNA repair, but its role in ECs remains surprisingly unexplored. The current study was designed to elucidate the regulated expression and function of SMARCA5 in diabetic ECs.Methods: SMARCA5 expression was evaluated in ECs from diabetic mouse and human circulating CD34+ cells using quantitative reverse transcription polymerase chain reaction and Western blot. Effects of SMARCA5 manipulation on ECs function were evaluated using cell migration, in vitro tube formation and in vivo wound healing assays. Interaction among oxidative stress, SMARCA5 and transcriptional reprogramming was elucidated using luciferase reporter assay, electrophoretic mobility shift assay and chromatin immunoprecipitation.Results: Endothelial SMARCA5 expression was significantly decreased in diabetic rodents and humans. Hyperglycemia-suppressed SMARCA5 impaired EC migration and tube formation in vitro, and blunted vasculogenesis in vivo. Contrarily, overexpression of SMARCA5 in situ by a SMARCA5 adenovirus-incorporated hydrogel effectively promoted the rate of wound healing in a dorsal skin punch injury model of diabetic mice. Mechanistically, hyperglycemia-elicited oxidative stress suppressed SMARCA5 transactivation in a signal transducer and activator of transcription 3 (STAT3)-dependent manner. Moreover, SMARCA5 maintained transcriptional homeostasis of several pro-angiogenic factors through both direct and indirect chromatin-remodeling mechanisms. In contrast, depletion of SMARCA5 disrupted transcriptional homeostasis to render ECs unresponsive to established angiogenic factors, which ultimately resulted in endothelial dysfunction in diabetes.Conclusion: Suppression of endothelial SMARCA5 contributes to, at least in part, multiple aspects of endothelial dysfunction, which may thereby exacerbate cardiovascular complications in diabetes.
Tips and pitfalls in the diagnosis and treatment of bronchial asthma
Authors: Al-Hajjaj Mohamed Saleh
Published: March 2023

Bronchial asthma (BA) is one of the common presentations in the outpatient clinic. In most cases, diagnosis of BA is straightforward with typical history and pertinent physical examination. However, a significant number of patients who present or referred as BA, yet they lack the classical signs and symptoms of BA. The pattern of symptoms and past history of similar episodes are crucial in the diagnosis. Several diseases can mimic asthma presentation including air hunger, acute bronchopulmonary aspergillosis, and vocal cord dysfunction need to be identified and managed accordingly. Even if BA can be easily managed in most cases, there are several obstacles that can prevent a good asthma control. Compliance with medication, incorrect use of different devices, and steroid phobia may lead to a poor control of BA. A better control of BA can be obtained by additional measures in the treatment plan. These include step-up and step-down method of therapy, offering influenza and pneumococcal vaccines, attention to comorbidities, and utilizing telemedicine for easy approach and follow-up.

Published: March 2023

A non-pneumatic tire (NPT) has a unique design that offers certain advantages
over the common pneumatic tire. This tire is resistant to punctures and immune
to blowouts. The present work aims to improve the aerodynamic design of the NPT
by keeping the structure of the spokes hexagonal but varying other design
features like tread pattern and adding material and filets. CAD designs were
developed using Fusion 360 software and computational fluid dynamics (CFD)
analysis is carried out using SimScale software. The variation of camber and yaw
angles has been conducted with both tread and material enhancement. There was a
decrease in drag and lift when the material was added to all the tires, but for
all variations of yaw and camber, an increase in drag and lift was seen. The
analysis is further extended to see the effect of a wheel well on the
aerodynamic performance of the NPT. A decrease in drag and lift of nearly 33.2%
and 94.5%, respectively, were observed with a wheel well.
From Biography to a Net of Interpretations: The Plurality of Approaches to Vladimír Karfík’s work
Authors: Bartošová Nina
Published: March 2023

The aim of this study is to justify a partial shift from the biographical approach in the author’s ongoing research into the work of architect Vladimír Karfík’s, especially if that research is directed towards raising present-day appreciation of his output. The inspiration comes from pragmatic aesthetics, as understood by philosopher Richard Shusterman, which considers the possibility of appreciating a work of art and architecture without the premise of one universal truth. The “net of interpretations” metaphor suggests that different interpretative lines can be perceived as equivalent in all their diversity, and there is no single “true” image of the work that lies underneath. The proposition of the study is argued both on a theoretical level and through the analysis of existing publications devoted to Karfík’s work and personality.

Published: March 2023

Fisheries industry is a vital sector of Sri Lanka’s economy and each departing and arriving fishing vessel should have gone through ample security check by the harbor authorities. But with the COVID 19 pandemic and social distancing procedure, harbor authorities are facing difficulties detecting and recognizing fishing vessels by getting on the boats as usual. Also, currently harbors are using a paper-based system for recording the information on boat departures and arrivals. This leads to the inefficiency of harbor management process, delays in rescue missions and failures of security missions. To solve these problems, this paper introduces a Boat Recognition and Automated Harbor Management System (BRAHMS) which is based on YOLO v5 algorithm. In this research, a novel de-skewing method is discovered for the slanted license plate recognition process. The de-skewing process aims for three main approaches: auto de-skewing, manual de-skewing and a hybrid de-skewing which uses both auto and manual processes together.

Utilization of Enterobacter cloacae WW1 Biomass for Biosorption of Lead(II) from Aqueous Solution
Authors: Thongkrua S. , Kasuya A.
Published: March 2023

The present study evaluated lead biosorption by Enterobacter cloacae WW1 isolated from tannery wastewaters under different initial Pb2+ concentrations, biomass concentrations, and contact times. The results showed that at an initial Pb2+ concentration of 80 mg.L-1, the optimal conditions for living cells were a biomass concentration of 7 g.L-1 and a contact time of 120 min. For non-living cells, biomass was a biomass concentration of 4 g.L-1 and contact time of 45 min, which provided removal efficiencies of 92.03 ± 0.10% and 99.51 ± 0.01%, respectively. The maximum biosorption capacity obtained for non-living cells using an initial Pb2+ concentration of 640 mg.L-1 was 76.65 ± 0.05 mg.g-1. The equilibrium data followed the Langmuir and Freundlich models for living cells, and the data for non-living cell biosorbents fit the Langmuir model. The biosorption kinetics for living and non-living cells fit well with a pseudo-second-order kinetic equation. SEM-EDX analysis clearly showed the morphology and presence of Pb2+ particles on non-living cell surfaces after biosorption. In addition, the results revealed that functional groups such as hydroxyl, amino, carboxyl, amide, and phosphate groups on the bacterial cell surface detected by FTIR were associated with the binding of Pb2+ ions. The results indicated that E. cloacae WW1, a lead-resistant bacterium, can be used as an alternative biosorbent for lead removal from wastewater.

Authors: Oyebode O. J. , Waterway O.
Published: March 2023

Characterization and treatment of greywater are major environmental issues in most nations of the world. The research aims to characterize and evaluate recycling technologies using an analytical hierarchical process for Afe Babalola University Ado-Ekiti (ABUAD) community. A survey was conducted around ABUAD to determine the number of functioning boreholes and active water systems in the area, the total population of students was derived from the total head count of each room and student in each hostel, and a population projection for the next 3 years was conducted to determine the rate at which the student body will grow in terms of future water demands, and daily water volume and questionnaires were used to collect data. Before developing the small-scale model of the greywater filter system (consisting of activated carbon, shaft sand, pebbles, cotton fiber, and gravel), water grey samples were gathered from several ABUAD locations to evaluate the pollution level of each greywater source. A total of 88 students (43 males and 45 females) replied to the survey, revealing their high need for clean water and their dissatisfaction with the water supply in their respective hostels. The water quality tests conducted in the various locations of ABUAD reveal high levels of total dissolved solids (TDS) and turbidity, particularly in the girl’s hostels, and the water was discovered to be predominantly alkaline. After passing a sample of greywater through the small-scale greywater filtering device, it was determined to be effective, since it produced clear, reusable water and a greywater filtration system in ABUAD will yield favorable outcomes.
Influence of Different Particle Sizes of Sediments on the Lower Reaches of the Basin and its Significance in the Liao River Governance
Authors: Yang Chen
Published: March 2023

Based on the sand volume and sedimentation volume data for different particle size (PS) groups, the relationship between the annual scouring and silting amount of the Juliu River-Liujianfang section and the yearly sediment volume entering the downstream river channel was established. The critical values of sediment storage and release for the downstream river channel were obtained. It was found to decrease with an increase in the sediment particle size. The correlation coefficient between the annual scouring and silting amount of the Juliu River-Liujianfang section and the annual sediment volume entering the downstream river channel increased with the coarsening of sediment PS. It indicated that the sediment size was proportional to the sediment amount (SA) entering the river channel. As the sediment size increased, the deposition amount increased due to the variation of unit sediment amount. Based on the treatment and achievement of source areas with sediment sizes larger than 0.05 mm, it is significant to concentrate on treatment areas with sediment sizes larger than 0.10 mm.

Published: March 2023

Vertical flow-constructed wetlands (VFCW) are well-established, cost-effective, and sustainable options for wastewater treatment. Along with organic matter removal, wetlands are helpful in the removal of microbial pathogens. This study focuses on understanding the bacterial pathogen removal efficacy of three different design types of VFCWs and understands the best designs for the efficient removal of pathogens in a tropical climate. The three wetlands studied for removal efficiency were (a) two-stage vertical flow constructed wetland (TSVFCW), (b) Single-stage vertical flow constructed wetland (SSVFCW), and (c) single-stage saturated vertical flow constructed wetland (SSSVFCW). Results revealed that all three types of wetlands were effective in removing pathogenic bacteria. Still, TSVFCW was found to be more efficient in pathogen removal (Total Coliforms, Shigella spp., Salmonella spp., Pseudomonas spp., Vibrio spp., Enterococcus faecalis) 7.04 ± 0.17, 6.53 ± 0.08, 4.0 ± 0.42, 7.67 ± 0.08, 5.73 ± 0.70 and10 5.23 ± 0.96 Log10 reductions respectively compared to SSVFCW (5.28 ± 0.18, 5.18 ± 0.09, 3.74 ± 0.74, 6.98 ± 0.01, 3.97 ±0.32, 4.74 ± 1.08 Log10 reductions respectively) and SSSVFCW (4.48 ± 0.46, 4.83 ± 0.15, 2.74 ± 0.44, 6.71 ± 0.03, 4.31 ± 0.49, 5.03 ± 1.20 Log10 decreases respectively). For abiotic factors (Chemical oxygen demand, total Kjeldahl nitrogen, and phosphorus) also TSVFW shows better efficiency (45 ± 8.7, 24.7±4.5 and 3.1, ± 0.2 g.m-2, respectively) than SSVFCW (12 ± 1.3, 7.6 ± 0.4 and 1.8 ± 0.2 g.m-2 respectively) and SSVFCW (6.3 ± 1.1, 7.7 ± 0.1 and 1.2 ± 0.1 g.m-2 respectively). However, the removal efficiency of both single-stage wetlands was comparable.
Use of Ground Glass Waste as Aggregate Filler in Concrete

Published: March 2023

The disposal of the huge volume of glass waste is one of the significant environmental issues that need to be addressed. One of the efficient ways to solve this problem is to incorporate ground glass waste in concrete mixtures. However, its inherent surface smoothness and microcracks within the glass particle harm the hardened properties of concrete. Minimizing the particle size and controlling the amount of cement in the mixture can reduce the adverse effect of using glass in concrete. This study utilized ground glass waste (850 μm) as aggregate filler in a concrete mix. More specifically, this study investigated the effect of paste volume (Vp) on the properties of fresh and hardened concrete with ground glass waste as aggregate filler. Based on the test results, ground glass waste as aggregate filler negatively affects the workability of fresh concrete, but increasing the amount of paste can mitigate it. Vp values in terms of void volume (Vv) in the aggregates of 1.6Vv and 1.8Vv achieved satisfactory consistency of fresh concrete. In addition, the concrete compressive strength increased when increasing Vp. The test results have shown that ground glass waste has the potential to be utilized as aggregate filler in concrete mixtures.

Published: March 2023

Breakfast cereal is one of the common foods for children’s nutrition. It is made from sugar, barley, calcium carbonate, salt, maize, peanuts, molasses, and honey. Therefore, assessing the levels of radioactivity in breakfast cereal is essential for children’s health. Gamma-ray spectrometry NaI(Tl) was used to measure the radiation hazard in ten samples collected from the Iraqi market. The corresponding radiation dose quantities and hazard indices were also calculated. The average concentrations of 226Ra, 232Th, and 40K were found to be 18.195, 20.965, and 796.500 (Bq.kg-1). The annual effective dose equivalent (AEDEin), annual ingestion dose (AID), and the risk of cancer incidence (ELCR) were all seen to be within the accepted levels, except the annual gonadal equivalent dose (AGED). Radiation hazard index values (i.e., Iγ, Iα, and Hin) were noticed to be lower than unity, except Iγ was much higher than the internationally permissible limits for the samples of BGF5, BGF6, and BGF7 recommended by UNSCER2000. Therefore, the study findings reveal that this type of cereal can be considered a safe feeding material for children’s health.
FaultMeter: Quantitative Fault Attack Assessment of Block Cipher Software
Authors: K Keerthi , Rebeiro Chester
Published: March 2023

Fault attacks are a potent class of physical attacks that exploit a fault njected during device operation to steal secret keys from a cryptographic device. The success of a fault attack depends intricately on (a) the cryptographic properties of the cipher, (b) the program structure, and (c) the underlying hardware architecture. While there are several tools that automate the process of fault attack evaluation, none of them consider all three influencing aspects.This paper proposes a framework called FaultMeter that builds on the state-of-art by not just identifying fault vulnerable locations in a block cipher software, but also providing a quantification for each vulnerable location. The quantification provides a probability that an injected fault can be successfully exploited. It takes into consideration the cryptographic properties of the cipher, structure of the implementation, and the underlying Instruction Set Architecture’s (ISA) susceptibility to faults. We demonstrate an application of FaultMeter to automatically insert optimal amounts of countermeasures in a program to meet the user’s security requirements while minimizing overheads. We demonstrate the versatility of the FaultMeter framework by evaluating five cipher implementations on multiple hardware platforms, namely, ARM (32 and 64 bit), RISC-V (32 and 64 bit), TI MSP-430 (16-bit) and Intel x86 (64-bit).
Pushing the Limits of Generic Side-Channel Attacks on LWE-based KEMs - Parallel PC Oracle Attacks on Kyber KEM and Beyond
Authors: Rajendran Gokulnath , Ravi Prasanna , D’Anvers Jan-Pieter , Bhasin Shivam , Chattopadhyay Anupam
Published: March 2023

In this work, we propose generic and novel adaptations to the binary Plaintext-Checking (PC) oracle based side-channel attacks for Kyber KEM. These attacks operate in a chosen-ciphertext setting, and are fairly generic and easy to mount on a given target, as the attacker requires very minimal information about the target device. However, these attacks have an inherent disadvantage of requiring a few thousand traces to perform full key recovery. This is due to the fact that these attacks typically work by recovering a single bit of information about the secret key per query/trace. In this respect, we propose novel parallel PC oracle based side-channel attacks, which are capable of recovering a generic P number of bits of information about the secret key in a single query/trace. We propose novel techniques to build chosen-ciphertexts so as to efficiently realize a parallel PC oracle for Kyber KEM. We also build a multi-class classifier, which is capable of realizing a practical side-channel based parallel PC oracle with very high success rate. We experimentally validated the proposed attacks (upto P = 10) on the fastest implementation of unprotected Kyber KEM in the pqm4 library. Our experiments yielded improvements in the range of 2.89× and 7.65× in the number of queries, compared to state-of-the-art binary PC oracle attacks, while arbitrarily higher improvements are possible for a motivated attacker, given the generic nature of the proposed attacks. We further conduct a thorough study on applicability to different scenarios, based on the presence/absence of a clone device, and also partial key recovery. Finally, we also show that the proposed attacks are able to achieve the lowest number of queries for key recovery, even for implementations protected with low-cost countermeasures such as shuffling. Our work therefore, concretely demonstrates the power of PC oracle attacks on Kyber KEM, thereby stressing the need for concrete countermeasures such as masking for Kyber and other lattice-based KEMs.
RDS: FPGA Routing Delay Sensors for Effective Remote Power Analysis Attacks
Authors: Spielmann David , Glamočanin Ognjen , Stojilović Mirjana
Published: March 2023

State-of-the-art sensors for measuring FPGA voltage fluctuations are time-to-digital converters (TDCs). They allow detecting voltage fluctuations in the order of a few nanoseconds. The key building component of a TDC is a delay line, typically implemented as a chain of fast carry propagation multiplexers. In FPGAs, the fast carry chains are constrained to dedicated logic and routing, and need to be routed strictly vertically. In this work, we present an alternative approach to designing on-chip voltage sensors, in which the FPGA routing resources replace the carry logic. We present three variants of what we name a routing delay sensor (RDS): one vertically constrained, one horizontally constrained, and one free of any constraints. We perform a thorough experimental evaluation on both the Sakura-X side-channel evaluation board and the Alveo U200 datacenter card, to evaluate the performance of RDS sensors in the context of a remote power side-channel analysis attack. The results show that our best RDS implementation in most cases outperforms the TDC. On average, for breaking the full 128-bit key of an AES-128 cryptographic core, an adversary requires 35% fewer side-channel traces when using the RDS than when using the TDC. Besides making the attack more effective, given the absence of the placement and routing constraint, the RDS sensor is also easier to deploy.

Are Accounting Gurus in Sync with Petty Traders’ Indigenous and Innovative Record-Keeping?
Authors: Amoah-Mensah Aborampah
Published: March 2023

Although record-keeping by small- and medium-scale enterprises (SMEs) has been extensively researched, there is a paucity of research on indigenous and innovative record-keeping. This paper examines the indigenous and innovative record-keeping practices of petty traders in Kumasi, Ghana, with a focus on how they gain a competitive advantage. In addition, it aims to derive a theoretical model from the findings of the study using grounded theory. Lastly, this research seeks to understand if academic and accounting practitioners are in sync with petty traders’ record-keeping. The results from focus group discussions show that petty traders engage in both indigenous (stones or sticks tallying, item or goods tallying, marking of walls, note pad or exercise books, pieces of tied clothes or polythene bags, vendors and customers, family and friends, guarantors and witnesses, susu collectors, and wooden boxes or tin cans) and innovative (mobile money, use of audio-visuals, and videotapes) record-keeping practices. The results also demonstrate that indigenous and innovative record-keeping of petty traders gives them a competitive advantage. A theoretical model is derived from the results using grounded theory. This study adds to the literature on record-keeping practices and has implications for further research.
Grounding Qualitative Medical Research in Coherence, Not Standards
Authors: Isaac Carol A. , Behar-Horenstein Linda
Published: March 2023

Qualitative research publications have become more prominent in medical journals. However, in medical discourse, those researchers who are adhere to postpositivist (quantitative) paradigm often criticize diverse qualitative inquiry for a perceived lack of rigor. We suggest that qualitative research, just like quantitative research should be guided by methodological coherence rather than prescriptive standards. Coherence is defined as an alignment between epistemology, theoretical perspective, methodology, methods, and research questions. In the medical field, a lack of training in methodological diversity, a long-held post-positivist privileging, and insufficient methodological dialogue, promulgates reliance on quantitative analyses. Neglecting to articulate sufficient methodological detail has caused other researchers to assert that qualitative research lacks rigor. Providing methodological details permits study replication. Qualitative researchers have been discussing the necessity for this scholastic imperative for decades, although it is relatively new in medical discourse. The authors’ interest in this topic stems from an analysis of rigor within qualitative medical educational articles since 2012 (CI), and reviewing grant proposals, doctoral research studies, and publishing in medical journals (LBH, CI). During out work, we observed that while the literature reviews in these submissions are frequently excellent, the method and results sections often lacked the essential linkages that are needed to support methodological coherence. Owing to our interest, we undertook a critical review while using deductive content analysis of forty qualitative articles in a top-tier medical journal. The purpose of this paper is to provide examples of coherence with the qualitative medical article reviewed. Our aim is to provide scholarly guidance to novice medical researchers and practitioners. The authors believe that this information will support increased scholarly integrity and coherence in the qualitative research publications, specifically in medical education and more generally in other discipline-related qualitative studies. We believe that both researchers and readers of qualitative research in academic medicine need to know about these issues so they can capably provide evidence of coherence.
“Chains Weigh Heavy”: Body Mapping Embodied Experiences of Anxiety
Authors: Vaughan Priya , Tewson Anna , Morgan Patricia , Boydell Katherine
Published: March 2023

Anxiety has both cognitive and somatic dimensions as is ubiquitous at a population level. We report on an arts-based research workshop gathering data on embodied experiences of anxiety and non-anxiety. We developed an innovative short body mapping workshop to collect data and undertook thematic analysis to analyse textual and visual data. 35 body maps were produced. “Tightness,” “pain,” and “heaviness” were the most frequently expressed embodied sensations of anxiety. By contrast, when not feeling anxious, participants’ bodies primarily felt “energetic,” “ordered,” and “open.” Anxiety was most frequently felt in the stomach, head and heart. 35 Participants mostly used an abstracted, rather than figurative, visual language to depict anxiety. Conclusions: Participants reported diverse bodily experiences of anxiety, some of which correlate with commonly identified somatic symptoms of anxiety. Other symptoms were unique to participants. The richness and diversity of anxiety experiences elicited during workshops indicates that the brief body mapping approach has potential application in future research, and in other settings.
Review of the Disaster Management Laws after 「the Itaewon Disaster」
Authors:   National Public Law Review, Kim Jung-Hoon
Published: March 2023

Since the Itaewon disaster on October 29, 2022, Korea unfortunately has been an opportunity to look back on disaster management. Due to its nature, the Disaster Management Laws always provide a big issue from unexpected accidents. The current constitution is stipulated “The State shall endeavor to prevent disasters and to protect citizens from harm therefrom.” in Article 34(6). This means that the state has the obligation to protect people from life-threatening hazards in natural disasters and industrial societies and there are various individual actual laws, including 「Framework Act on the Management of Disaster and Safety」. Disasters are stipulated in various areas of the legal system as they have the properties of occurring in various forms and times in various places. Therefore, Korea's disaster-related laws lack connection with each other, and there are various ministry-specific management organizations, so they do not have a unified systematic and unified organization to respond to disasters. There is criticism that the Framework Act on Disaster and Safety Management does not sufficiently perform its status and role as a basic law on disaster preparation. There is a need for the legislation on disaster management to clarify the concepts and contents related to disaster and safety, and to systematically organize safety-related legislation. As a way to improve the legislation on disaster management, the concept of legal terms that can overcome the abstraction of safety-related concepts should be unified and clear among disaster-related legislation. From this, systematization between laws and regulations should be achieved to eliminate confusion in the application of the law. Organizational law requires the establishment of a safety system and the completion of a legal system through cooperation between the central and local governments to respond to disasters for the safety of the people, and it is also important to establish a private cooperation system in responding to disasters. In practice, basic rules such as disaster response behavior rules of structural Organizations with efficiency and speed should be prepared in detail.

Published: March 2023

In this short philosophical and discursive paper, the main objective is to reassess a new emergent role of the history of mathematics in order to bring about greater diversity and engagement in the mathematical sciences. The discussion is based around the project undertaken at a North London university and their partner pre-university college, which piloted the larger national project in the UK in the local context. The success of the project, it is further suggested, would greatly benefit from a framework in which the history of mathematics as a humanistic discipline is closely related to viewing mathematics as a virtuous practice. We also include a short summary about the lives and careers of two Serbian mathematicians, Judita Cofman, and Milica Ilić-Dajović, to showcase how learning about the ways in which marginalisation takes place can help students position themselves and contextualise their priorities as they enter the professional mathematics landscape.
THE UNDERSTANDING OF RELATIONAL TERMS IN COMPARE‑COMBINE WORD PROBLEMS ON DIFFERENT LEVELS OF EDUCATION

Published: March 2023

Routine word problems are thoroughly described and categorized to combine, change, and compare problems. This paper investigates how 2nd, 4th, and 6th-grade students solve integrated combine and compare problems. We used the integrated combine and compare problems with consistent language (CL) formulation, inconsistent language (IL) formulation, or more complex structure. Our research sample consists of 44 students in 2nd grade, 48 students in 4th grade, and 42 students in 6th grade from schools in Belgrade. The results show that stu- dents are more successful in solving problems with CL than with IL formulation at all levels of education. Students from the 2nd, 4th, and 6th grade are equally successful in solving the CL problem. The surprising result is the nonexistence of a significant difference in the achieve- ment of students in 4th and 6th grade on the IL problem, which could indicate an obstacle in the development of relational term understanding after introducing algebra into mathematical education. Low achievement on the problem with more complex structure showed that students have issues with the modeling process and that they are not eager to use algebraic strategies or graphical representations. These results imply a need for a systematic approach to teaching routine problems after introducing algebra in mathematics education.

Attendance is an activity that must be carried out in various activities, one of which is in teaching and learning activities in schools, lectures, seminars, meetings, teacher attendance, and others. In teaching and learning activities in schools and terms of teacher absenteeism, attendance is an important parameter because it can affect student success and teacher performance in the continuity of teaching and learning activities, especially at SMK Nurul Muhtadin Kibin. At this time, the attendance system at SMK Nurul Muhtadin Kibin school attendance activities for teachers and students is still using the conventional way, namely the teacher in the class mentions the names of students one by one and then puts a dot on the attendance book for each class that has been prepared by the school and for attendance teachers have administrative officers who go around checking each class by using paper as a medium for recording teacher absences. This method is certainly very risk when the attendance book is lost or damaged so that the loss of attendance information that has been carried out, as well as for making teacher attendance reports takes a little longer and risks errors in reporting teacher absenteeism. The use of QR CODE in the development of a web-based Teacher and Student Attendance Information System is expected to solve existing problems. The system that built by this author uses the PHP version 7 programming language, MySQL as the database media. The development method that will be used by the author is to use the Waterfall method. With the presence of a teacher and student attendance information system using this QR Code, the author to overcome the problems faced by making it easier for students and teachers who want to take attendance.

Introduction: Liver damage due N-diethylnitrosamine (DEN) is a global health challenge. The aim of this study was to assess the efficacy of roselle (Hibiscus sabdariffa L.) calyces’ water-extract as a Hepatoprotective material against liver damage induced by DEN in rats. Material and methods: Twenty-five (25) adult female albino Wistar rats were grouped randomly into five groups (Gs): G1, Normal healthy animals (act as control); G2, DEN; G3, Roselle extract; G4, DEN + roselle-extract; G5, DEN + nanoselenium. Tissue malondialdehyde (MDA) as oxidative stress marker, and antioxidant enzymes, superoxide dismutase (SOD) and catalase (CAT) were measured. Also, caspase-3 as apoptotic marker and tumor necrosis factor-alpha (TNF-a) as inflammatory factor, were assessed. Results: The results revealed decrease in MAD level and significant increase in antioxidant markers, SOD and CAT in DEN-group compared with control group. Moreover high increase in apoptotic marker, caspase-3; and significant decrease in TNF-a in DEN-group were recorded compared with normal control. Administration of roselle-extract led to significant increase in MDA and decrease in SOD and CAT parameters. In addition, high decrease in caspase-3 and increase in TNF-a was noticed. These findings were ensured by histopathological results. Conclusion: The roselle-extract improve liver architecture, and might be involved in the hepatoprotective activity against DEN exposure. Further studies are needed for elucidation clinical applications of the plant bioactive materials and explore its mode of action in attenuating and preventing carcinogenesis.

Time Domain Reflectometry (TDR) System Application in Light Water Reactors In-Core (A Short Memorandum)
Authors:   Galaxy Advanced Engineering, Albuquerque, New Mexico, 87111, United States of America, Chief Executive Officer, Zohuri Bahman
Published: March 2023

A Time Domain Reflectometry (TDR) is not a new technology in industry. This concept has been known for its monitoring and sending of signals for the detection of cable tampering in unattended radiation detection systems. The instrument concept under investigation would allow for unmanned cable integrity measurements, remote surveillance reporting, and the locating of cable faults and/or tampering. by a national laboratory such as the Pacific Northwest National Laboratory (PNNL). TDRs are a very simple instrumentation design configuration, using pulse signals to send the pulse through the cable. Their firmness depends on the width of the pulse sent by them. That is why narrow pulse signals are preferred. However, because narrow width pulses have high frequencies, they have a limitation. High-frequency signals get distorted inside large cables. However, in this short memorandum, not only do we introduce this instrument as reminder to the readers, what this device is, we also show its application as a water level monitoring instrument by Instrumentation and Control (I&C) as an In-Core tool within the family of Light Water Reactors (LWRs) during their safe operation domain and during their commercialization as Generation-IV (GEN-IV) of Small Modular Reactors (SMRs) as a consideration among the designers and engineers of these reactors within the nuclear industry. These devices could be developed and used extensively for measuring the water level In-Core of family of LWRs as a probe for measuring such levels in reactor vessel confinement and collecting surface runoff. It could be designed, developed, and calibrated, then field-tested accordingly. This device could be used as an additional safety factor in the computation of setpoints from Probabilistic Risk Assessment (PRA), specifically if we are using such a device in new Advanced Concept Reactor (ARC) technology of SMRs of GEN-IV.
