Effect of Low Dose Ionising Radiation on the Amount of Mitochondrial Common Deletion and D-Loop Tandem Duplication in Human Peripheral Whole Blood
Authors: Deli Gábor , Kulin Flóra , Angyalné Pataki Ágnes
Published: May 2024

The Hungarian Defence Forces assume a significant role in disaster prevention, including nuclear accident prevention tasks, so both the command and executive staff can stay in the higher-than-natural dose area. The current “gold standard” microscopic method aimed at determining the radiation dose suffered is the dicentric chromosome assay (DIC), although sensitive and accurate, it is very time-consuming. Monitoring changes in the amount of common deletion (CD) of mitochondrial DNA (mtDNA) and in the D-loop a tandem duplication (TD) of mtDNA may be a reliable marker of exposure to ionising radiation. This work used the PCR method to investigate how CD and TD change in human blood samples after X-ray irradiation. The CD appears to be a particularly useful marker, as its maximum is below the threshold for clinical symptoms. This work is the first to show the relationship between radiation and tandem duplication. The TD we investigated occurredmore frequently in irradiated human blood samples than native ones. During the future development of the diagnostic tool, both CD and TD are informative and would be used together in a PCR system to detect acute and cumulative irradiation. In recent years, more and more health institutions are dealing with molecular biological diagnostic work. In a disaster situation, if the laboratory capacity of the Hungarian Defence Forces would not be sufficient for this, more external laboratories can be involved for PCR measurements than for traditional microscopic work.
Comparison of the Protection of Critical Healthcare Infrastructures in Germany and Hungary
Authors: Mészáros István
Published: May 2024

In 2008, the European Union regulated the basics of the protection of critical infrastructures in a directive. The Member States therefore had to ensure that – in addition to the freedom of the method and means of implementation – the provisions of the directive were transposed into their national legal order. Accordingly, some Member States may define different detailed rules. The detailed rules related to the protection of critical infrastructures (e.g. the designation thresholds) are not public in several Member States, but in Germany and Hungary they have been recorded at the legislative level. In my study, I compare the rules related to the protection of critical healthcare infrastructures, including inpatient care institutions, primarily based on legal sources and the experiences of my study tour in Germany, from the selection criteria system to crisis planning. The good practices resulting from the differences and similarities to be discovered can help to revise and standardise the rules and practices related to the protection of critical health infrastructures.

Authors: Silva Hellba Karts Maria , Cavalcante Lilian de Souza , Almeida Giovanna Andrade Souza , Pereira Jarson Pedro da Costa , Luz Marcella Campos Lima
Published: May 2024

Introdução: A sarcopenia é uma condição associada ao mau prognóstico, incluindo o risco para pior toxicidade gastrointestinal em pacientes com câncer submetidos a tratamento quimioterápico. Objetivo: avaliar a associação entre o risco de sarcopenia e a toxicidade gastrointestinal de pacientes idosos em quimioterapia. Método: Estudo observacional com coleta transversal, envolvendo 60 idosos diagnosticados com tumores sólidos, selecionados por conveniência, em regime de quimioterapia exclusiva ou combinada. O risco de sarcopenia foi avaliado por meio dos questionários SARC-F e SARC-CalF. O diagnóstico de desnutrição foi avaliado pela mini avaliação nutricional reduzida (MAN-r). Resultados: Entre os pacientes incluídos, o risco de sarcopenia (SARC-F) foi observado em 15%. Ao utilizar o SARC-CalF, esse número cresceu para 33,3%. Foi observado que uma maior pontuação do SARC-F esteve independentemente associada ao maior número de sintomas relativos à toxicidade gastrointestinal. Além disso, maiores escores do SARC-F (mais risco) se associaram à menor força de preensão palmar e aos menores escores da MAN-r. Elevados escores do SARC-CalF se associaram à menor força de preensão palmar e menores escores na MAN-r. Conclusão: Os achados sugerem que o SARC-F pode ser uma ferramenta guia para intervenções relacionadas à melhora do estado muscular, potencialmente prevenindo o elevado número de sintomas relacionados à quimiotoxicidade gastrointestinal.

Authors:   Nizhyn Mykola Gogol State University, Nizhyn, Ukraine, Nesterenko S.A.
Published: May 2024

The development of competencies is an important aspect for every individual, as it ensures the achievement of high results in work and allows you to perform tasks more efficiently and professionally. In the modern world, there are concordant concepts of “competence” and “competency”, which are interpreted by scientists in different ways. The purpose of this article is to study the origin of the concepts of “competence” and “competency”, to clarify the definitions of each concept and the expediency of using these interpretations by teachers of general secondary education institutions. Conclusions. Establishing the relationship between the concepts of “competence” and “competency”, we consider it appropriate to focus on their distinction. In accordance with the studied interpretations of these concepts, we note that competency is interpreted by a certain institution or the state as a predetermined requirement for knowledge, skills, abilities that a person must have in order to be successful in the required field of activity. In turn, competence is an asset of the individual, which determines the qualitative level of knowledge, skills and the ability to implement them based on one’s own experience, which manifests itself at a critical moment through the ability to find a connection between the situation and knowledge, in making adequate decisions on an urgent problem. It is important to note that competence is directly related to competency, as it specifically outlines a given range of issues in the field of activity that a person should be well versed in, i.e. competent. Thus, competence is a predetermined set of knowledge, skills, and abilities, and competency is actually a qualitative characteristic of the acquisition of this knowledge and skills, which is manifested in the process of practical activity. Key words: competence, competency, language competence, competence-based approach, pedagogical competence, professional competence of a teacher.

Authors: Nainggolan Riris Tua , Maulani Denia
Published: May 2024

Taxes are a form of obligation that people often ignore, resulting in tax arrears and fines. For this reason, the government then created a program, namely tax whitening. Therefore, researchers conducted research to understand the consequences of reducing motor vehicle tax on the realization of motor vehicle tax revenue in Indonesia in 2020-2022. The research model applies qualitative using library research methods. Researchers used primary and secondary sources consisting of articles, books, laws and online news. Data collection applies documentation techniques with research instruments in the form of research material classification checklists. Data analysis applies a descriptive data analysis model which includes reading data sources, making notes, processing notes, then compiling reports. The result of tax whitening could result in positive feedback on Indonesian motor vehicle tax revenues in 2020-2022. The percentage of motor vehicle tax revenue realization increases every year. In nominal terms, PKB increases by IDR 3-5 trillion every year. This means that the more often tax relief is carried out, the level of taxpayer compliance will also increase and tax revenues from motor vehicle taxes will also increase.

BIODIVERSITY CONSERVATION EFFORTS AMONG MUSLIM COUNTRIES: EVIDENCE FROM THE ORGANIZATION OF ISLAMIC COOPERATION COUNTRIES
Authors: Ismail Roslina , Abdullah Mohd Kamarulnizam , Abd Ghani Latifah
Published: May 2024

According to mainstream literature, Muslim countries often lag behind in terms of environmental sustainability despite their beingfully compliant with global environmental regulations. This raises the question of whether this applies to all aspects of environmentalconservation. Therefore, this paper aims to evaluate the effectiveness of biodiversity conservation efforts in countries that are members of the Organization of Islamic Cooperation (OIC) and determine whether a consistent growth trend in biodiversity conservation can be identified. The study employs semi-quantitative and policy-science methods, analysing data from Yale University’s Biodiversity and Habitat Protection Index from 2010 to 2020. The findings show a significant increase in biodiversity conservation performance over the ten-year study period. Interestingly, low-income countries outperformed their wealthier OIC counterparts in terms of biodiversity conservation, despite having the lowest economic development status. This positive trend highlights the effectiveness of essential biodiversity policies and measures adopted in these Muslim countries. Furthermore, these results align with Stern’s approach, which argues that economic expansion can have diverse impacts on environmental quality, leading to the rejection of the Environmental Kuznets Curve hypothesis in the context of biodiversity conservation in Muslim countries. The study emphasises the need for further research into the nature of biodiversity policies among low-income nations. The policy ideas and solutions from these countries can provide valuable insights for combating biodiversity loss within OIC countries and globally, contributing to achieving Sustainable Development Goals (SDGs). Additionally, it has the potential to enhance the capacity of OIC countries in biodiversity conservation and their role in supporting fellow Muslim nations in achieving the SDGs.

A Regeneration Model for Mitigation Against Attacks on HTTP Servers for Mobile Wireless Networks
Authors: Akinwale Abiodun , Olajubu Emmanuel , Aderounmu Adesola
Published: May 2024

The widespread expansion of the internet has fueled a global surge in the utilization of various online transactions, with a significant portion of such services operating on mobile web platforms. Simultaneously, the deployment of innovative Mobile Ad Hoc Network (MANET) technologies and mobile applications has grown as solutions for diverse tasks. Unfortunately, this progress has attracted the attention of hackers, who continually devise new strategies to exploit the vulnerabilities inherent in mobile networks. This study aims to address the escalating challenges posed by cyber threats in the era of widespread internet expansion, particularly focusing on securing mobile web platforms against sophisticated attacks such as Structured Query Language Injection (SQLi) for web-based database solutions and Denial of Service (DoS/DDoS) for various applications. In response to the identified vulnerabilities, this paper proposes an HTTP regeneration (HReg) model that not only detects various cyber-attacks but also ensures the uninterrupted provision of critical services during such incidents. The model introduces an innovative regeneration algorithm capable of scanning both the connection channel and web application to detect attacks, creating survivable connections within the underlying TCP engine to replace compromised ones during an ongoing attack. In simulated environments using OMNeT++, where the server is subjected to attacks, the experimental results demonstrate the efficacy of the model. The response and performance metrics, including throughput (73%), delivery ratio (68.8%), delay (3s), and network load, showcase the model's ability to detect and neutralize attacks. A comparison with state-of-the-art approaches highlights the superior performance of the regeneration model, attributed to its additional survivability layer. While the regeneration model proves robust in simulated environments, its real-world application may encounter limitations. Future research should explore these limitations to enhance the practical applicability of the proposed model. The proposed HReg model's resilient performance under attack conditions ensures the survivability of web-based applications. This innovative approach offers practical implications for securing mobile web platforms, providing continuous delivery of critical services even in the face of persistent and evolving cyber threats. This research addresses a significant gap in existing efforts by not only focusing on attack detection but also emphasizing the development of a survivable TCP connection for HTTP servers during attacks. The introduced regeneration model stands out for its unique ability to maintain service continuity, showcasing originality in the approach to cybersecurity in the context of web-based applications.

Published: May 2024

In cellular networks, with the increase in demand, designing a base station (BS) with less energy consumption remains a challenge for researchers. Also, in a heterogeneous network that is dense in nature, the distribution of numerous small BS has become a challenging issue in terms of expanding the cost of energy. In this paper, we investigate an optimized nature-based cluster sleep technique for reducing the power consumption in the BS as well as the interference in the network. The small BS are grouped along with the interference, which is assumed to be the cluster, which is quite large, where the fire fly (FF) algorithm is applied to frame the sleep technique for the small BS. These FF algorithms, which are based on fire fly attractiveness behavior, improve connectivity among the base stations in an energy-efficient way. The outcomes reveal that the projected sleep technique with the FF algorithm reduces the power consumed by the BS and also gives satisfactory performance for mobile users. The results were compared with the other techniques, such as BS conventional sleep mode and BS sleep mode with LEACH. The proposed method outperformed the other techniques.

Rarely does a history teacher have the opportunity of relating a historic moment first-hand to his or her students. In the summer of 1963 I was a 22-year-old newly minted college graduate, headed for work on a master's degree that fall. As my home was in the suburbs of Washington, D.C., I had been able for several years to pick up summer jobs in the various federal agencies. That summer I was at the then Department of Health, Education and Welfare, doing just what, I have long forgotten. In that hot summer of the civil rights movement word had spread that there was to be a massive march on the nation's capital.
Martin, Jr., Brown V. Board Of Education - A Brief History With Documents
Authors: Adebayo Akanmu
Published: May 2024

This is a valuable companion to longer works on the history of the African American experience, especially the less commonly taught but extremely important history of the movement for civil rights in the United States-the struggle for equal access to educational opportunities. The "brief history" is brief enough (40 pages) and the array of documents reproduced here is wide enough to make this reviewer conclude that Martin has provided a text that students and teachers will consult, and that the general reader will like to keep.
The "brief history" of the Brown decision is presented as the "Introduction" to the book. This traces the history from the emergence of Jim Crow in the immediate post-emancipation era to the NAACP's successful legal battles against inequality and discrimination culminating in Brown v. Board of Education of Topeka, Kansas (1954). Martin presents the history as a "legal struggle." It was a struggle that seemed to touch on all aspects of American life, including the legal profession itself. Among the decisions that "nibbled away at Plessy" (Plessy v. Ferguson [1896]) were Gaines v. Canada ( 193 8) and Sipuel v. Oklahoma State Regents (1948).

BACKGROUND: Adenoid hypertrophy producing obstructive airway symptoms is the most commonly encountered pediatric ENT problem. Clinical symptoms in combination with lateral nasopharyngeal x ray is a reliable technique for selection of children requiring surgical intervention.
METHODOLOGY: The current cross sectional prospective study was conducted among 250 children aged 3-12 years with clinical symptoms and radiological evidence suggestive of enlarged adenoids, at Pediatric outpatient department of a tertiary care center, Dhaka, during 1-year period.
RESULT: In our current study, majority children (74%) with adenoid hypertrophy were 3-6 years old followed by 26% between 7-12 years. 66% children were male and 34% were female with a male to female ratio of 1.9:1. 44% children were from lower class family and history of atopy was present among 54% children. Clinical grading of adenoid hypertrophy was done on the basis of presenting symptoms (mouth breathing, snoring, sleep disturbances and adenoid facies) and radiological grading was done from calculating adenoid nasopharyngeal ratio. Correlation between clinical scoring and radiological grading of adenoid hypertrophy among study population was observed. Clinical score of 0-4, 5-8, 9-12 and 13-16 was graded clinically into Grade I, II, III and IV respectively. Highly significant p value (.000) was observed in Grade II clinical and radiological grade of enlarged adenoid. The remaining clinical and radiological grade of enlarged adenoids showed significant p value .031, .024 and .019 among grade I, III and IV respectively.
CONCLUSION: Though various diagnostic modalities for detection of degree of obstruction caused by enlarged adenoids are available, clinical scoring in combination with radiological grading can be effectively used to select patients requiring surgical intervention for pediatric adenoid hypertrophy.

Background: The presence of tumor cells within lymphatic or blood vessels in the surrounding tissue of a malignant tumor indicates the possibility of cancer spreading (metastasis) to other parts of the body. Lymphovascular invasion (LVI) is a significant pathogenic feature in invasive breast cancer that can provide valuable information about the tumor's aggressiveness and influence therapy options.
Objective: To the association of LVI with prognostic factors in breast cancer.
Methods: This cross-sectional study was conducted in the Department of Surgery, Sir Salimullah Medical College and Mitford Hospital, on 52 adult breast cancer patients who received Breast Conserving Surgery (BCS) or mastectomy. No patients with neoadjuvant therapy (recurring, breast cancer, metastases, or advanced breast cancer were excluded). Patients' demographic data, clinical data, and lab diagnoses were obtained. Histopathology and immunohistochemistry were performed on all samples. ER, PR, and Ki-67 were correlated with histological results. Pathologists diagnosed LVI in surgical resection tissue. All data were validated for consistency after collection. Data were analyzed using SPSS 12.0. A p value < 0.05 was considered statistically significant.
Results: The presence of ER and PR was significantly higher in cases where LVI was negative. On the other hand, the presence of Ki-67 was significantly higher in cases where LVI was positive. It was observed that cases with LVI positive had higher stages of lymph nodes metastasis and tumor grading. It was also found that the Ductal type of breast cancer was significantly higher in cases where LVI was negative. Additionally, LVI positive case was found to be significantly higher among aged people.
Conclusion: The presence of lymphovascular invasion has a negative association with ER, PR, and ductal type breast cancer and is positively associated with ki67, high grade, and greater lymph node metastasis.
