Published: June 2023

Electrical storm (ES) refers to a life-threatening condition characterised by three or more episodes of ventricular tachycardia (VT), ventricular fibrillation (VF), or appropriate implantable cardioverter defibrillator (ICD) shocks in 24 hours. We report a case of a 58-year-old man who suffered recurrent episodes of sustained VT despite appropriate defibrillation and antiarrhythmic drug therapy. On stepwise evaluation, arrhythmogenic right ventricular cardiomyopathy (ARVC) was considered the most likely substrate for his dysrhythmia. He was managed conservatively on antiarrhythmic drugs with no further clinical episodes of VT, and ICD implantation for secondary prophylaxis was recommended.
In silico study of aminothiazole, benzohydrazide, namoline, piridine, and parnate derivatives as Jumonji domain histone lysine demethylase (KDM1A, KDM4A, KDM4C, KDM4E, AND KDM5B) inhibitors in prostate cancer
Authors: Muttaqin Fauzan Zein , Fahlevi Revi , Muhammad Hubbi Nasrullah
Published: June 2023

Background: Prostate cancer is the second most common type of cancer in men. The histone lysine demethylase enzyme is believed to be one of the genetic factors that cause prostate cancer. Based on in vivo testing, a group of compounds from the aminothiazole, benzohydrazide, pyridine, namoline, and parnate classes have been experimentally proven to be inhibitors of the histone lysine demethylase enzyme.
Objective: This study aimed to investigate the interaction of 20 compounds consisting of aminothiazole, benzohydrazide, pyridine, namoline, and parnate derivatives with histone lysine demethylase enzymes (KDM1A, KDM4A, KDM4C, KDM4E, and KDM5B) in silico.
Method: Molecular docking was performed using Autodock Tools v.4.2.3 to obtain the affinity of test compounds against the target molecule. This was followed by molecular dynamics (MD) simulation of some test compounds with the lowest inhibition constant using Gromacs software. Toxicity prediction was conducted to predict the safety of the test compounds.
Result: The docking results revealed the top five compounds for each receptor with the lowest inhibition constant and free binding energy value (∆G), suggesting the best affinity to histone lysine demethylase enzymes. The results from MD showed that the compounds with the codes aminothiazole, pyridine, parnate 1, parnate 2, and parnate 5 were stable when bound to the KDM1A receptor. The toxicity test results also indicated that the test compounds were safe and had a low health risk, as they were neither genotoxic nor non-genotoxic carcinogens.
Conclusion: Based on the research results, it can be concluded that compounds with the codes aminothiazole, pyridine, parnate 1, parnate 2, and parnate 5 can serve as inhibitors of histone lysine demethylase enzymes on the KDM1A receptor and are stable when bound to the receptor.

Published: June 2023

The theme of this work is "market segmentation and offer targeting using neural discriminant analysis" for classification purposes. The data provided by modern applications are usually large in size and their classification may be disturbed. In this work, we will give a contribution of data mining to market segmentation and offer targeting using neural discriminant analysis. The main interest of this work is to offer decision-makers a better vision of their customers, allowing them to better manage and satisfy them by proposing products likely to be purchased by them; to make targeted marketing or a particular offer to a group of customers with similar characteristics and consumption behaviors; to know what to offer to the new customer who comes to the company by assigning him to a group of customers in which the habits, preferences towards a product or a group of products are known. Our approach therefore predicts the class of a new customer who comes to the company; the class is predicted after the customer has made his first purchase.. Individuals are placed in the class with the highest probability. In this case, the client will be assigned to the appropriate class with the marketing services.

Published: June 2023

Zero-knowledge proof is a critical cryptographic primitive. Its most practical type, called zero-knowledge Succinct Non-interactive ARgument of Knowledge (zkSNARK), has been deployed in various privacy-preserving applications such as cryptocurrencies and verifiable machine learning. Unfortunately, zkSNARK like Groth16 has a high overhead on its proof generation step, which consists of several time-consuming operations, including large-scale matrix-vector multiplication (MUL), number-theoretic transform (NTT), and multi-scalar multiplication (MSM). Therefore, this paper presents cuZK, an efficient GPU implementation of zkSNARK with the following three techniques to achieve high performance. First, we propose a new parallel MSM algorithm. This MSM algorithm achieves nearly perfect linear speedup over the Pippenger algorithm, a well-known serial MSM algorithm. Second, we parallelize the MUL operation. Along with our self-designed MSM scheme and well-studied NTT scheme, cuZK achieves the parallelization of all operations in the proof generation step. Third, cuZK reduces the latency overhead caused by CPU-GPU data transfer by 1) reducing redundant data transfer and 2) overlapping data transfer and device computation. The evaluation results show that our MSM module provides over 2.08x (up to 2.94x) speedup versus the state-of-the-art GPU implementation. cuZK achieves over 2.65x (up to 4.86x) speedup on standard benchmarks and 2.18× speedup on a GPU-accelerated cryptocurrency application, Filecoin.
JitSCA: Jitter-based Side-Channel Analysis in Picoscale Resolution

Published: June 2023

In safety and security conscious environments, isolated communication channels are often deemed necessary. Galvanically isolated communication channels are typically expected not to allow physical side-channel attacks through that channel. However, in this paper, we show that they can inadvertently leak side channel information in the form of minuscule jitter on the communication signal. We observe worst-case signal jitter within 54 ± 45 ps using an FPGA-based receiver employing a time-to-digital converter (TDC), which is a higher time resolution than a typical oscilloscope can measure, while in many other systems such measurements are also possible. A transmitter device runs a cryptographic accelerator, while we connect an FPGA on the receiver side and measure the signal jitter using a TDC. We can indeed show sufficient side-channel leakage in the jitter of the signal by performing a key recovery of an AES accelerator running on the transmitter. Furthermore, we compare this leakage to a power side channel also measured with a TDC and prove that the timing jitter alone contains sufficient side-channel information. While for an on-chip power analysis attack about 27k traces are needed for key recovery, our cross-device jitter-based attack only needs as few as 47k traces, depending on the setup. Galvanic isolation does not change that significantly. That is an increase by only 1.7x, showing that fine-grained jitter timing information can be a very potent attack vector even under galvanic isolation. In summary, we introduce a new side-channel attack vector that can leak information in many presumably secure systems. Communication channels can inadvertently leak information through tiny timing variations, known as signal jitter. This could affect millions of devices and needs to be considered.
Kavach: Lightweight masking techniques for polynomial arithmetic in lattice-based cryptography
Authors: Aikata Aikata , Basso Andrea , Cassiers Gaetan , Mert Ahmet Can , Sinha Roy Sujoy
Published: June 2023

Lattice-based cryptography has laid the foundation of various modern-day cryptosystems that cater to several applications, including post-quantum cryptography. For structured lattice-based schemes, polynomial arithmetic is a fundamental part. In several instances, the performance optimizations come from implementing compact multipliers due to the small range of the secret polynomial coefficients. However, this optimization does not easily translate to side-channel protected implementations since masking requires secret polynomial coefficients to be distributed over a large range. In this work, we address this problem and propose two novel generalized techniques, one for the number theoretic transform (NTT) based and another for the non-NTT-based polynomial arithmetic. Both these proposals enable masked polynomial multiplication while utilizing and retaining the small secret property.For demonstration, we used the proposed technique and instantiated masked multipliers for schoolbook as well as NTT-based polynomial multiplication. Both of these can utilize the compact multipliers used in the unmasked implementations. The schoolbook multiplication requires an extra polynomial accumulation along with the two polynomial multiplications for a first-order protected implementation. However, this cost is nothing compared to the area saved by utilizing the existing cheap multiplication units. We also extensively test the side-channel resistance of the proposed design through TVLA to guarantee its first-order security.
PROLEAD_SW

A decisive contribution to the all-embracing protection of cryptographic software, especially on embedded devices, is the protection against Side-Channel Analysis (SCA) attacks. Masking countermeasures can usually be integrated into the software during the design phase. In theory, this should provide reliable protection against such physical attacks. However, the correct application of masking is a non-trivial task that often causes even experts to make mistakes. In addition to human-caused errors, micro-architectural Central Processing Unit (CPU) effects can lead even a seemingly theoretically correct implementation to fail to satisfy the desired level of security in practice. This originates from different components of< the underlying CPU which complicates the tracing of leakage back to a particular source and hence avoids making general and device-independent statements about its security.PROLEAD has recently been presented at CHES 2022 and has originally been developed as a simulation-based tool to evaluate masked hardware designs. In this work, we adapt PROLEAD for the evaluation of masked software, and enable the transfer of the already known benefits of PROLEAD into the software world. These include (1) evaluation of larger designs compared to the state of the art, e.g. a full Advanced Encryption Standard (AES) masked implementation, and (2) formal verification under our new generic leakage model for CPUs. Concretely, we formalize leakages, observed across different CPU architectures, into a generic abstraction model that includes all these leakages and is therefore independent of a specific CPU design. Our resulting tool PROLEAD_SW allows to provide a formal statement on the security based on the derived generic model. As a concrete result, using PROLEAD_SW we evaluated the security of several publicly available masked software implementations in our new generic leakage model and reveal multiple vulnerabilities.

Authors: Wudil Adamu Ahmed , Muhammad Rislanudeen
Published: June 2023

The purpose of this study is to conduct a bibliometric analysis of research on financialization from 2014 to 2023. A range of articles on financialization was collected using the Scopus database. The articles analyzed cover ten years, spanning from 2014 to 2023. The survey utilized a Scopus analyzer to obtain the analysis results such as the number of documents published by year, source, and country. To analyze the co-authorship, co-occurrences, citation analysis, and bibliographic coupling, VOSviewer Version 1.6.18 was utilized. After applying limits to open access, year, subject area, document type, publication stage, keyword, source type, and language, a database search resulted in 166 articles on financialization published between 2014 and 2023. Statistical and network analyses reveal that most articles were published in 2019 and 2021, with the United Kingdom contributing the highest number of documents. The network analysis of various parameters indicates a decline in research on financialization during the period under study, suggesting the need for further work in this area in the upcoming years. The study also includes statistical analysis of authors, documents, countries, and affiliations.
Moodle as a Tool to Reduce Transactional Distance at an Open Distance and e-Learning University
Authors: Sevnarayan Kershnee
Published: June 2023

Despite the expansion of e-learning and the adoption of innovative learning management systems to support students, higher education institutions are still struggling under the burden of digital exclusion, hence increasing the transactional distance between lecturers and students. The research was conducted at a South African Open Distance and eLearning university and attempted to (1) understand how the Moodle site is organized to influence transaction distance, (2) identify students’ perceptions of the Moodle site to enhance their academic writing skills, and (3) identify if Moodle is an enabler or disabler to their learning. This article uses a qualitative participatory action research design and draws on the theory of transactional distance. Using observations, open-ended evaluation questions, and a focus group discussion, the study found that students appreciated the communication and interaction facilitated by the lecturers. Despite the challenges that students experienced, the transactional distance was reduced between lecturers and students. Although the findings of this study cannot be generalized on a broader scale, findings are in line with similar studies, amplifying the critical role of the perceptions and challenges of first-year students in HEIs to bring about the required change.

Published: June 2023

When one learns a certain language, he/she should also learn its culture. This is because languages and cultures are integrated.Â  For example, to acquire meanings, language students need to understand the culture of the language they are learning. This study seeks to determine the challenges faced by English language learners in understanding Islamic beliefs and western cultures. This was a descriptive qualitative study that utilized semi-structured interviews to acquire data. Interviews were conducted with eight pupils from the Islamic boarding school Ar-Risalah in West Sumatra. The result of interviews showed that the majority of learners acknowledged that they experienced cross-cultural hurdles in English learning because of being culturally insensitive, misunderstanding of cultural contents in the language materials, and formal intervention regarding the textbook. Students are confused to differentiate cultures shared by Islamic values and Western cultures as those Islamic values are not vividly depicted in English textbooks. Therefore, students have difficulties understanding English. It is imperative that future research investigate this topic, since culture and language are inseparable, in which people learning a certain language are also required to learn its culture.
The Effect of Work-Life Balance on Higher Education Employee Performance: Moderation of Organizational Support and Job Satisfaction Level
Authors: Malau April Gunawan
Published: June 2023

This study examines the effect of work-life balance on employee performance in higher education institutions, especially maritime education and training institutions in Jakarta. In addition, organizational support and job satisfaction were chosen to moderate the WLB relationship and the employee's performance. Using data from 197 respondents in fiveinstitutions, this study processed the data using principal component factor analysis (PCFA) and ordinary least squares (OLS) regression. The test results show that two of the three research hypotheses are accepted. First, WLB is empirically proven to have a positive effect on employee performance. Second, job satisfaction strengthens the positive relationship between WLB and employee performance. Third, organizational support is not proven to moderate the WLB relationship and employee performance. The findings in this study indicate that WLB enables employees to carry out personal and work obligations effectively and efficiently. Employees who can do that will be able to fulfill their commitment to providing the best for the organization where they work. However, in practice, organizations are sometimes unable to understand the complexities of each employee's personal life, so the support provided is not following the needs of employees. Finally, despite all the limitations, this research has academic and practical implications because research attempting to moderate WLB on employee performance is still rare. The practical implication is that higher education leaders must understand the needs of employees so that they can balance their personal and work lives.

This study was conducted with the aim of valorising papaya seeds. To do this, papayas were purchased in order to extract the seeds, then these seeds were dried at different temperatures (50°C/72h; 75°C/48h and 105°C/24h) in the oven. The dried seeds were ground with a mixer to obtain a flour. The effect of temperature on the physicochemical and functional characteristics of this flour was determined. The results of the physicochemical parameters showed that the 50°C dried seeds had the best pH (67.6), fat (5%), protein (32%) and fibre (17.9%). On the other hand, the 100°C temperature recorded parameters such as dry matter (92.17%), carbohydrates (41.12%) and energy value (334.48Kcal). The best ash content was recorded at 75°C (7.80%). On the other hand, no significant difference was recorded for these three temperatures on the functional properties of the papaya seeds. Given the good physicochemical and functional characteristics of papaya seeds we can say that these seeds could be recommended to people suffering from obesity and digestive disorders.

In this study, we examine the determinants of a successful derivative futures contract and explore whether an exhaustive checklist of criteria such as the one proposed by the Securities and Exchange Board of India (SEBI) guarantees the success of a commodity contract. This study has important implications for contract design and new product launches. More market-orientated risk management mechanisms such as hedging via derivatives could allow farmers and producers to manage their risk and efficiently discover true prices. The government's vision to develop a progressive and sustainable commodities market in India is facing a fundamental issue: What makes a futures contract successful? This study attempts to analyse this question. Academics and policymakers have long deliberated on the conditions that make a contract successful. This study revisits those conditions in the context of Indian agricultural futures contracts and assesses the dispositions made by the SEBI’s long list of criteria as well as insights from prior studies about the determinants of a successful contract. Tea satisfies almost all the criteria with either first or second rank among the three compared products. Therefore, we can conclude that Tea has the necessary and potential characteristics for introduction in the Commodity Derivative Market of India and progress forward as a successful commodity

In today's inclusive and diverse society, students' first exposure to diverse backgrounds, opinions, and skills occurs in the classroom. Social-emotional learning (SEL) aims to help individuals understand their ideas and feelings, become more self- aware, and build empathy for others to assist all students to be successful. It is the teacher's responsibility to raise concerns and affection for students and to attend to their needs and feelings. Pre-service teacher preparation is training and development that teachers get before they start their teaching career as role models for their students and to help them become part of a collaborative and supportive learning community. This research discusses the level of social-emotional learning and the social dimension of pre-service teachers and analyzes its relationships. In this study, descriptive correlational research was used. A research-made survey questionnaire was used as the research instrument. The following are significant findings of the study: Pre-service teachers' levels of social-emotional learning in terms of self-awareness, self-management, social awareness, relationship skills, and responsible decision-making are highly competent. Pre-service teachers' levels of social dimensions in terms of belongingness at school, social learning experiences, and relationships with teachers, peers, and parents are highly competent. The research reflects that it is possible to integrate SEL in a classroom setting considering classrooms as the central location of learning where the students spend the majority of their time.

This study examines the effect of consolidation of Deposit Money Banks (DMBs) on credit access risk in rural areas of Nigeria after a decade of the consolidation exercise. Secondary data on total value of credits to rural areas was obtained from the CBN bulletin for the period 1994 to 2014. This period includes 10 years of pre consolidation and 10 years of post-consolidation. Mann Whitney U test was used in analysing the data to test for significant difference in the total credit to rural areas before and after consolidation in Nigeria. The result revealed that there was a significant increase in access to DMBs’ credit by rural customers of DMBs in the post consolidation era when compared to the pre-consolidation era. The result may be is explained by the role of technology in banking. It is recommended amongst others that government should provide infrastructures like good access roads to the rural areas, electricity and support investments in Information and Communication Technology (ICT) in the rural areas as this will encourage the penetration of financial services into the hinterlands.

Published: June 2023

The activity of Citayam Fashion Week (CFW) in the Dukuh Atas Train Station Area at Jl. Sudirman Jakarta, which is dominated by children aged in their teens who appear wearing modern and quirky clothes, has managed to attract the attention of the public in particular netizens. But behind this phenomenon, the CFW event raises concerns because the majority of participants are children aged 15-18 years who spend their daily time in the area without parental supervision. This study aims to analyze the CFW phenomenon from the perspective of Family Sociology and Fulfillment of Child's Rights. This study uses a descriptive qualitative research method with secondary data. The results of the study found that children who were involved in CFW activities did not get their welfare rights from their parents. In accordance with the definition of the Child Protection Act, where a person who is not yet 18 years old is a child whose rights are protected by the state, and in development they still need the guidance, supervision and affection of their parents. Parents are obliged to provide direction and accompany the growth and development of children and fulfill children's rights including the right to education, the right to a family environment and other rights. The main thing in human development is the fulfillment of basic needs, where if these basic needs are not met, it will have a significant impact on the growth and development of children. In conclusion, the Citayam Fashion Week phenomenon has a negative side where parents or families who are supposed to be the parties to fulfill children's rights and prepare children to become qualified human resourceshave neglected to carry out their responsibilities.

During the process of production activities, there are factors or incidents that affect the health of workers, such as hazardous working environments, prolonged fixed working postures, accidents caused by machinery, etc., resulting in a decrease or even permanent loss of work ability. Accidents occurring during labor or illnesses arising from work conditions incur costs for medical treatment, functional recovery, purchase of assistive devices for daily living, costs of caregivers in case of disability or severe illness, reduction or loss of income due to the inability to perform previous works, or the need to find a new job suitable for the health condition. Economic and social development has impacted the occupational risks of workers and changed the protection needs of workers against these risks. Therefore, countries, including Vietnam, have promulgated policies for workers involved in work related accidents and occupational diseases, with the cornerstone being the social insurance regime for work related accidents and occupational diseases. This writing analyzes the achieved results and limitations of the policy for workers involved in work related accidents and occupational diseases in Vietnam, and proposes solutions to improve this policy.

Published: June 2023

Long linked with exclusivity, glamor, and distinction, luxury has recently undergone a paradigm shift because of the success of LVMH. In addition to dominating its sector, this conglomerate of luxury goods has had a significant influence on society and culture. LVMH has a significant impact on a variety of topics, including globalization, the environment, and the world of fashion. We will examine the different ways that LVMH has influenced society and culture in this dissertation, concentrating on two important strands: cultural influence and globalization. Through an examination of LVMH's association with high culture, its collaborations with artists and celebrities, and its role in preserving cultural heritage, we will consider the company's impact on culture. We will also explore LVMH's expansion into various regions, its contribution to the globalization of culture, and the controversies it has faced, including cultural appropriation and poor labor practices. By examining LVMH's impact and influence, we hope to shed light on the complex and multifaceted role of luxury goods in society today.

Waste management is a worldwide issue other than climate change and global warming.  In the ASEAN, there is an extraordinary increase in solid waste traced to urbanization, industrial development, and economic growth.  While the Philippines enacted the Ecological Solid Waste Management Act, local governments passed the Environment Code.  This study determined the extent of implementation of the city ordinance on solid waste management of communities in terms of the variables assessed by a sample size of 67 implementers and 384 residents identified by stratified random sampling.  It also investigated the challenges encountered by the respondents in the implementation.  Likewise, the differences were determined according to the geographical location of coastal, upland, and lowlands and when respondents were grouped according to designation.  Using descriptive analysis, the results revealed that, as a whole, implementation of the provisions of the city ordinance is, to a great extent, with waste generation as the highest while handling and on-site storage the lowest, but several challenges were encountered. The comparative analysis revealed no significant difference in the extent of implementation when respondents were grouped according to designation in all areas except waste disposal.  However, there was a significant difference when communities were grouped by geographical location, with lowland residents rating higher than the rest.  Three groups of challenges emerged from the study: administrative, procedural, and policy issues.
