An analysis of over 30 species of euglenoids for accumulation of euglenophycin identified six additional species producing the toxin; and six of the seven <I>E. sanguinea</I> strains produced the toxin. A phylogenetic assessment of these species confirmed most taxa were in the Euglenaceae, whereas synthesis capability apparently has been lost in the <I>Phacus, Eutreptiella, and Discoplastis</I> branches.</P>

Refugee Health: A Global and Multidisciplinary Challenge

Zimba Olena,Gasparyan Armen Yuri 대한의학회 2023 Journal of Korean medical science Vol.38 No.6

The ongoing war and evolving humanitarian crisis in Ukraine have forced millions of women, children, and elderly people to flee the war zones and relocate across Poland, other European countries, and elsewhere in the world. As a result, numerous health issues have emerged in the host countries, ranging from the refugees’ low immunization coverage to psychological distress and multimorbidities. Humanitarian support and multidisciplinary approach to the issues may help to improve the refugees’ health and well-being. Involving relocated medics in rehabilitation and medical care of their compatriots may offer psychosocial and health benefits.

Designing, Conducting, and Reporting Survey Studies: A Primer for Researchers

Zimba Olena,Gasparyan Armen Yuri 대한의학회 2023 Journal of Korean medical science Vol.38 No.48

Survey studies have become instrumental in contributing to the evidence accumulation in rapidly developing medical disciplines such as medical education, public health, and nursing. The global medical community has seen an upsurge of surveys covering the experience and perceptions of health specialists, patients, and public representatives in the peri-pandemic coronavirus disease 2019 period. Currently, surveys can play a central role in increasing research activities in non-mainstream science countries where limited research funding and other barriers hinder science growth. Planning surveys starts with overviewing related reviews and other publications which may help to design questionnaires with comprehensive coverage of all related points. The validity and reliability of questionnaires rely on input from experts and potential responders who may suggest pertinent revisions to prepare forms with attractive designs, easily understandable questions, and correctly ordered points that appeal to target respondents. Currently available numerous online platforms such as Google Forms and Survey Monkey enable moderating online surveys and collecting responses from a large number of responders. Online surveys benefit from disseminating questionnaires via social media and other online platforms which facilitate the survey internationalization and participation of large groups of responders. Survey reporting can be arranged in line with related recommendations and reporting standards all of which have their strengths and limitations. The current article overviews available recommendations and presents pointers on designing, conducting, and reporting surveys.

Multi-stage crypto ransomware attacks: A new emerging cyber threat to critical infrastructure and industrial control systems

Aaron Zimba,Zhaoshun Wang,Hongsong Chen 한국통신학회 2018 ICT Express Vol.4 No.1

The inevitable integration of critical infrastructure to public networks has exposed the underlying industrial control systems to various attack vectors. In this paper, we model multi-stage crypto ransomware attacks, which are today an emerging cyber threat to critical infrastructure. We evaluate our modeling approach using multi-stage attacks by the infamous WannaCry ransomware. The static malware analysis results uncover the techniques employed by the ransomware to discover vulnerable nodes in different SCADA and production subnets, and for the subsequent network propagation. Based on the uncovered artifacts, we recommend a cascaded network segmentation approach, which prioritizes the security of production network devices.

Recent Advances in Cryptovirology: State-of-the-Art Crypto Mining and Crypto Ransomware Attacks

( Aaron Zimba ),( Zhaoshun Wang ),( Hongsong Chen ),( Mwenge Mulenga ) 한국인터넷정보학회 2019 KSII Transactions on Internet and Information Syst Vol.13 No.6

Recently, ransomware has earned itself an infamous reputation as a force to reckon with in the cybercrime landscape. However, cybercriminals are adopting other unconventional means to seamlessly attain proceeds of cybercrime with little effort. Cybercriminals are now acquiring cryptocurrencies directly from benign Internet users without the need to extort a ransom from them, as is the case with ransomware. This paper investigates advances in the cryptovirology landscape by examining the state-of-the-art cryptoviral attacks. In our approach, we perform digital autopsy on the malware’s source code and execute the different malware variants in a contained sandbox to deduce static and dynamic properties respectively. We examine three cryptoviral attack structures: browser-based crypto mining, memory resident crypto mining and cryptoviral extortion. These attack structures leave a trail of digital forensics evidence when the malware interacts with the file system and generates noise in form of network traffic when communicating with the C2 servers and crypto mining pools. The digital forensics evidence, which essentially are IOCs include network artifacts such as C2 server domains, IPs and cryptographic hash values of the downloaded files apart from the malware hash values. Such evidence can be used as seed into intrusion detection systems for mitigation purposes.

Comorbidities in the COVID-19 Pandemic: Scopus-Based Bibliometric Analysis

Fedorchenko Yuliya,Zimba Olena 대한의학회 2023 Journal of Korean medical science Vol.38 No.11

Background: Comorbidities attract enormous attention amid the coronavirus disease 2019 (COVID-19) pandemic. Mapping knowledge based on these clinical conditions is increasingly important since the pandemic is still raging and primarily affecting subjects with chronic diseases and comorbidities. Clinical presentation and complications of COVID-19 are still hot topics which are explored in numerous evidence-based publications. The aim of this study was to analyze Scopus-indexed COVID-19 papers covering comorbidities. Methods: Searches through the Scopus database were performed on September 19, 2022 using the following keywords: “Diabetes mellitus” OR “Cardiovascular Diseases” OR “Rheumatic Diseases” OR “Obesity” OR “Malignancies” AND “COVID-19.” All retrieved articles were analyzed using the following categories: document type, authorship, keywords, journal, citation score, country of origin, and language. Using the software tool VOSviewer version 1.6.18, we visualized the network of authors and keywords co-occurrence of the most prevalent comorbidities reported in connection with COVID-19. Results: Reports on COVID-19 and diabetes mellitus (DM) were most frequently published (n = 12,282). The US was the most productive country (n = 3,005) in the field of COVID-19 and comorbidities. There were 1,314 documents on COVID-19 and rheumatic diseases which is the least number in comparison with other comorbidities (COVID-19 and DM: 12,282, COVID-19 and cardiovascular disease: 9,911, COVID-19 and obesity: 7,070, and COVID-19 and malignancies: 1,758). Conclusion: This mapping of COVID-19-related documents in connection with comorbidities may prioritize future research directions.

Research Integrity: Where We Are and Where We Are Heading

Zhaksylyk Alikhan,Zimba Olena,Yessirkepov Marlen,Kocyigit Burhan Fatih 대한의학회 2023 Journal of Korean medical science Vol.38 No.47

The concept of research integrity (RI) refers to a set of moral and ethical standards that serve as the foundation for the execution of research activities. Integrity in research is the incorporation of principles of honesty, transparency, and respect for ethical standards and norms throughout all stages of the research endeavor, encompassing study design, data collecting, analysis, reporting, and publishing. The preservation of RI is of utmost importance to uphold the credibility and amplify the influence of scientific research while also preventing and dealing with instances of scientific misconduct. Researchers, institutions, journals, and readers share responsibilities for preserving RI. Researchers must adhere to the highest ethical standards. Institutions have a role in establishing an atmosphere that supports integrity ideals while also providing useful guidance, instruction, and assistance to researchers. Editors and reviewers act as protectors, upholding quality and ethical standards in the dissemination of research results through publishing. Readers play a key role in the detection and reporting of fraudulent activity by critically evaluating content. The struggle against scientific misconduct has multiple dimensions and is continuous. It requires a collaborative effort and adherence to the principles of honesty, transparency, and rigorous science. By supporting a culture of RI, the scientific community may preserve its core principles and continue to contribute appropriately to society’s well-being. It not only aids present research but also lays the foundation for future scientific advancements.
