Instruction-Fetching Attack and Practice in Collision Fault Attack on AES
Authors: Jiang Huilong , Zhu Xiang , Han Jianwei
Published: October 2022

A Fault Attack (FA) is performed mainly under the data corruption model and poses a threat to security chips. Instruction corruption can enact the same purpose at the behavioral level, which is produced by interfering with the instruction system. Laser Fault Injection (LFI) on program memory during the instruction-fetching process, which we refer to as an instruction-fetching attack, is studied in this paper. This process bears the ability to produce a controllable instruction-fetching fault. Our work shows the implementation of the attack and its specific application case on an 8-bit microcontroller. The main contributions of this paper include: (1) We have mapped the sensitive areas precisely to the faulted instructions via laser injection and implemented controllable instruction tampering. (2) A Collision Fault Attack (CFA) scheme based on instruction-fetching fault is proposed. (3) The impacts of the faulted instructions are fully explored, including the influence on subsequent operations and key recovery. (4) The fault mechanism of the on-chip Flash is further investigated. Instruction-fetching fault means that the controller fetches a tampered instruction from the program memory under external interference, which likely gives rise to an invalid or incorrect operation. The experiment confirms that this specific fault can induce particular types of faults that are different to realize, e.g., the byte-fault model in CFA. The realization, application and mechanism of instruction-fetching fault are discussed in detail.
Noncommutative Bispectral Algebras and Their Presentations
Authors: Vasquez Campos Brian D. , Zubelli Jorge P.
Published: October 2022

We prove a general result on presentations of finitely generated algebras and apply it to obtain nice presentations for some noncommutative algebras arising in the matrix bispectral problem. By “nice presentation”, we mean a presentation that has as few as possible defining relations. This, in turn, has potential applications in computer algebra implementations and examples. Our results can be divided into three parts. In the first two, we consider bispectral algebras with the eigenvalue in the physical equation to be scalar-valued for 2×2 and 3×3 matrix-valued eigenfunctions. In the third part, we assume the eigenvalue in the physical equation to be matrix-valued and draw an important connection with Spin Calogero–Moser systems. In all cases, we show that these algebras are finitely presented. As a byproduct, we answer positively a conjecture of F. A. Grünbaum about these algebras.
An Analysis of the Risks during Personnel Transfers between Units Operating on the Water
Authors: Radwanski Krzysztof , Rutkowski Grzegorz
Published: October 2022

The purpose of this article is to analyse the risk related to the transfer of personnel between units operating on the water. Although several regulations exist, there are still a high volume of noncompliant personnel and passengers transfer arrangements throughout the industry. In light of this, it is the aim of this research to critically investigate and understand what is contributing to such a high level of noncompliance. In this paper, the authors outline the industry’s concern about poorly assembled ladders causing severe injuries or fatalities during personnel transfers and the preventive actions taken by various organizations. Mentioned demand is supported by the analysis of selected statistical data on maritime accidents and proposals of planned preventive actions. The study also presents an example of work risk assessment for typical personnel (pilot) boarding operations with the use of pilot ladders or other means of personnel transfer. The authors hope that the formal risk assessment (RA) presented in this paper will be the basis for the development of appropriate procedures and a checklist for each crew member involved in various transfer operations to or from the ship. As a result, the widespread use of such procedures, combined with adequate training of crews in hazard identification and risk assessment, should significantly improve overall safety in maritime transport systems.
Monitoring Ice Phenology in Lake Wetlands Based on Optical Satellite Data: A Case Study of Wuliangsu Lake
Authors: Huo Puzhen , Lu Peng , Cheng Bin , Zhang Limin , Wang Qingkai , Li Zhijun
Published: October 2022

It is challenging to obtain the ice phenology for a lake covered with a vast area of aquatic (shallow lake wetlands) using optical satellite data because possible clouds above the lake could contaminate the result. We developed a new method to tackle this challenge. Our target was Wuliangsu Lake, a large (330 km2) and shallow (1.6 m average depth) lake wetland in the Inner Mongolia Plateau. We used Landsat and Sentinel-2 imageries to extract the lake water boundary. The MOD09GQ/MYD09GQ dataset, having the highest spatial resolution among MODIS reflectivity products, was first selected to differentiate water and ice pixels. Then, we used the reflectivity state parameters containing cloud information in the dataset to filter out the cloud pixels. The ice phenology characteristics, such as freeze-up, break-up dates, and ice cover duration (ICD) between 2013 and 2022 were obtained. We further applied the air temperature correction technique to remove the outliers. The average of ICD in Wuliangsu Lake was about 127 ± 6 days. The freeze-up start and break-up end occurred on 17 November ± 5 days and 25 March ± 4 days, respectively. The remote sensing results agree well with the field observation, with a mean absolute error of 2 days. The algorithm can effectively remove the influence of aquatic plants and clouds on lake ice identification, thereby satisfying the needs of daily monitoring and ice phenology research in the lake wetlands.

Authors: Borbor Bridget Sena , Brew Lewis , Acquah Joseph
Published: October 2022

Unemployment is one of the major socioeconomic issues across the globe in which Ghana is no exception. The unavailability of jobs and its creation as being searched by persons belonging to the labour force actively looking for jobs makes the problem escalate rapidly in a growing economy. In this seven state model, we analysed into the three main economic sectors of Ghana to investigate how unemployment, employment, and newly created vacancy creation behave at equilibrium on the three economic sector levels. Moreover, we analysed how in a specific sector, the dynamics of the state variables control unemployment. Further analyses on the parameters indicated that, an increase in the rate of newly created vacancies results in a decrease in the number of unemployed persons and an increase in the number of employed. We assumed that a jobless person who is available for work but fails to make an effort to seek work is not part of the unemployed class among others. It was established that the model has one nonnegative equilibrium point. Lastly, we analyse the impact of perturbation of some parameters on the number of the unemployed and employed persons at equilibrium.unemployment
Remittances, Human Capital Nexus: Exploring the Role of Exchange Rate in Asia
Authors: Noor Iqra , Hussain Babar , Zahra Umbreen
Published: October 2022

This paper analyses the impact of remittances on human capital through the interaction of exchange rate in Asia. There is considerable debate regarding the relative contribution of international migrant’s remittances to sustainable economic development. Remittances are considered as temporary income. If exchange rate remains stable, then remittances will help in curtailing income hurdles of households as well as for government and helps to increase investment in education. Investment in education increases skill level of labor force and create an environment for long term growth. We use panel data of 54 Asian countries for the period of 1980-2020 and employ Hausman test and percentile analysis. The paper concludes that remittances have a positive and significant impact on human capital. However, the substituting relationship of remittances and exchange rate is observed in stimulating human capital in Asian countries. The developing countries having low growth, when exchange rate is overvalued (appreciate), it is not only pushing the economy further toward slower growth due to decrease in foreign competitiveness, increase in the current account deficit and increase unemployment but also cause to decrease main source of earning remittances growth in these countries. Therefore, this study suggests that the government of developing country implements such policies that helps in the stabilization of their currencies (manage floating exchange rate).

Liquified Petroleum Gas (LPG) fuel is currently an energy source being widely applied in many fields in Vietnam, making a significant contribution to the development of the national economy. This paper presents research results of applying LPG fuel used in motorbikes. The traditional liquid fuel system (gasoline) on a motorbike was replaced by an electronically controlled LPG fuel injection system. LPG fuel is designed to inject into the intake manifold. The injection quantity and injection timing are calculated and controlled by the electronic control unit through the calculation and analysis of the input of key parameters such as intake air pressure and temperature, throttle position, engine speed, and camshaft position. The testing results on real roads in an urban area show that the motorbike operates stably on flat and uphill roads. In addition, the cost of LPG fuelconsumption is less than that of the gasoline fuel consumption.

The objective of this study is to analyse the perception and awareness of the Expatriates and start-up businesses of the presence and value proposition of FinTech Services such as Payment/Banking, Lending and Crowdfunding in UAE. Data was collected using a survey-based questionnaire and respondents were chosen using convenient sampling method. Research design is a Cross-Sectional design. Data was collected between February to April 2020. The target audiences were Expats between the ages of 20-40 who have been living in UAE for at least 3 years. The level of awareness of most respondents in the FinTech services such a P2P lending; Robo Advising and Insurtech were fairly limited. The results discovered reflect a positive sign regarding the acceptance of these new FinTech services in UAE. From the findings, we can also notice that majority of the respondents are hoping for FinTech to be able to act as a secondary financing source apart from normal financing methods. And moreover, FinTech development in the UAE market could further increase business activities all throughout. Not many in depth studies on FinTech have been done across the world. In the context of UAE there were even lesser. This paper is one of its kinds in the region, which allows us to understand the awareness and perception of consumers towards technology and the financial industry using a broad spectrum of variables.
ENTERPRISE RISK MANAGEMENT: A REVIEW OF TWO
DECADES
Authors: Sakrabani Poorni , Ping Teoh Ai
Published: October 2022

This paper is a modest review spanning a 20-year period on Enterprise Risk Management. Enterprise Risk Management (ERM) deals with risks and opportunities which have an impact on value creation. Unlike traditional risk management (TRM) which is silobased, ERM is a holistic approach to risk management. Past studies have produced many contradicting results on the impact of ERM implementation on firm performance and also on the factors which are crucial for the successful implementation of ERM. As such, it is of absolute necessity to identify the determinants of ERM implementation and also how ERM improves performance. The research methodology for this paper began with a literature search for ERM-related articles from journals of various rankings from 2000 to 2020. Relevant papers for the review were selected by using the `going backward’ and `going forward’ process. Fifty research papers were selected in this manner for this review. Prior studies have used different variables to show how implementation of ERM can create value. Further, in recent years, there has been an increase in studies reporting the importance of strong ERM and its link with performance. Although only fifty research papers were reviewed for this paper, yet a few gaps in the extant literature on ERM have been identified. As such, suggestions on how future research can be conducted in this field are given at the end of the review.

As a Federal Statutory Body established by an Act of Parliament and gazetted on 3 September 2009 under Section 3 of the Enforcement Agency Integrity Commission Act 2009 [Act 700], the Enforcement Agency Integrity Commission (EAIC) is viewed as having a prominent role in enhancing the culture of integrity. The main purpose of this paper is to discuss the issues of integrity leakage currently facing by the EAIC including (i) Issues Concerning the Cultivation of Bribery Rewards and Corrupt Practices Among Civil Servants, (ii) Issues of Empowering Integrity Education in Sustainable Public Sector Governance, (iii) The Issue of Bureaucracy in Impairing the Efficiency of Human Resources and weakening the Organisational Administrative System, and (iv) The Issue of Exploitation by the Department’s Top Management for Personal Gain, and (v) The Issue of Cartels in Preventing the Loss of National Treasures. This paper applies secondary sources, such as research results published in journals, scholarly writing, online news sources, and public forums, to employ a qualitative methodology. According to the findings of the study found that civil servant’s breach of integrity is a serious concern if corruption and malpractice continue to occur. The study suggests that if the present system in the organisation is plagued by bureaucracy-related issues, it will worsen the situation of integrity in the government, resulting in the paralysis of the country’s governance delivery system. Hence, the crisis of integrity resulting from abuse of power, corruption, and breach of trust which can be interpreted as a frequent betrayal of trust among governments, civil servants, the private sector, and the general public places the nation at risk of having governance systems that are unreliable.

This study demonstrates the adaptation of Social Exchange Theory (SET) to examine the relationship between community attachment, community involvement, residents' place image, perceived benefits, perceived costs, and residents' support of Penang sustainable tourism development. A total of 196 data were collected face-to-face by a self-administered questionnaire to residents who live in George Town, Penang, Malaysia. A partial least squares (PLS) analysis was applied to assess the measurement model and the structural model. The proposed model showed useful predictive and explanatory power. Community involvement exhibited a significant effect on residents' support of tourism development. Surprisingly, community attachment, residents' place image, perceived benefits, and perceived cost were found to be insignificant to residents' support. There is a positive relationship between community attachment and residents' place image with perceived benefits and perceived costs. On the contrary, the influence of community involvement towards perceived benefits and perceived costs were not supported. The findings of this study provide a better understanding of the factors that influence residents' support on sustainable tourism development in Penang, Malaysia. Additionally, this study also provides insightful implications to regulatory bodies, owners of tourism businesses, and property developers.

In modern conditions of information and communication redundancy, IT technologies become a means of unauthorized interference in private life; a person tries to maintain a sense of ontological security by developing and manifesting sovereignty. The rapid development of the Internet has led to the fact that the problem of loss of privacy has become defined as one of the main risks of the information society. In the virtual world, the spatial understanding of boundaries is transformed and gradually loses its significance. The article presents a theoretical review of foreign and domestic research devoted to the study of psychological sovereignty of an individual in the aspect of regulation of communicative activity in relation to the boundaries of direct and virtual communication. In the context of the problems of sovereignty, the basic concepts reflecting the issues of privacy, psychological space, personality boundaries, personal autonomy are revealed. The relevance and practical significance of the study of the role of the sovereignty of social ties in the regulation of communicative activity in relation to the boundaries of direct communication and communication in the Internet space is indicated. The problems of safe communication on the Internet, the preservation of privacy, the sovereignty of an individual from the standpoint of the psychology of the subject are raised. The results of the study will contribute to the formation of value orientations regarding respect for personal space, preservation of sovereign existence in conditions of information saturation and risk-taking social existence. They can become the basis for the development of programs for psychological prevention and reduction of communicative deviations.

The article deals with the issue of inclusion development in education. The issue has a global importance. No matter how various are the processes of inclusion of the persons with disabilities into the system of educational relations in the modern world, there are many common issues that hinder the effective inclusion of special learners into the educational relations. This defines the urgency of this research, dedicated to the topic of inclusive education. This research presents the author’s vision on one of the actual directions in solving the issue of development of the inclusive education models. As one of the options in reducing the barriers in the way of development of the educational institutions with inclusive orientation, we consider the pedagogical facilitation. The issues of pedagogical facilitation are raised in scientific literature. The purpose of this article is opening the capabilities of facilitation in development of the inclusive processes in education, showing its value in implementation of the ideological, methodological and didactic basic of inclusive education. The article considers a general definition of facilitation as a social phenomenon; it gives a brief description of the researches faced to the facilitation issues. As a hypothesis of the research, an assumption was made that the active implementation of the facilitation method into the vital function of educational institutions would promote the efficiency of the inclusive processes. The methodological basis of the study is a person-centred paradigm, which stipulates the relationship of cooperation, co-creativity, non-violence. As a research method of this issue, a method of theoretical analysis that allows considering the facilitation in the system of inclusive education was adopted. Based on this method, research on the problems of inclusion in education and pedagogical facilitation were reviewed. The theoretical analysis allowed defining a close link between the two new phenomena in the system of modern education.
Inconformidade do enquadramento de corpos d'´água em Unidades de Conservação de Proteção Integral

O enquadramento de corpos de água é um instrumento previsto na Política Nacional de Recursos Hídricos que estabelece metas de qualidade da água a serem obrigatoriamente atingidas. Apesar de sua importância estratégica para a gestão qualitativa das águas, o enquadramento da bacia do Rio das Velhas encontra-se defasado, considerando as transformações no uso e cobertura do solo na bacia desde a sua publicação, especialmente sobre a bacia do Ribeirão da Prata, haja vista sua importância estratégica como potencial manancial e área de reconhecido interesse recreacional. Dessa forma, este trabalho visou revisar o enquadramento da referida bacia, elaborando uma proposta de atualização, baseada nos usos atuais e pretendidos, e no diagnóstico preliminar das condições de qualidade das águas do Ribeirão da Prata. Os principais usos identificados na bacia foram o recreacional, agrícola, urbano e a preservação ambiental. Neste contexto, a proposta deste trabalho enquadra em Classe Especial os cursos d’água dentro dos limites do Parque Nacional da Serra do Gandarela. Em Classe 1, os cursos d’água da margem direita do Ribeirão da Prata, e em Classe 2, apesar do atual quadro de poluição, os corpos hídricos inseridos na mancha urbana de Raposos. Embora os trechos analisados nas áreas de uso recreacional terem apresentado condições próprias de balneabilidade, os resultados verificados para fosfato e oxigênio dissolvido no Poço Azul (dentro dos limites do parque) e na Barragem de Raposos (fora do parque), demonstram a necessidade de um programa de monitoramento e gestão da atividade recreacional.

O constante crescimento dos municípios traz consigo uma série de benefícios, mas também necessita respeitar a natureza presente, não ignorando e nem mesmo prejudicando-a. Motivado pela hipótese de que estaria ocorrendo uma perda da cobertura vegetal no município de Três Rios (RJ) no decorrer dos últimos 20 anos, foi realizada uma pesquisa visando verificar se isso realmente estava ocorrendo. Para isso, foi produzida uma análise comparativa entre o uso e cobertura do solo no município utilizando como base imagens dos satélites Landsat 5 e 8, nos anos de 2000, 2010 e 2020 pautada no uso das Métricas Ecológicas da Paisagem. Após a análise individual dos mapas e gráficos gerados por meio de técnicas de geoprocessamento, foi observada a distribuição da “Vegetação Arbórea” nos três anos analisados, e, numa segunda etapa, foram utilizadas as Métricas Ecológicas da Paisagem para quantificar essa informação. Foi observado um aumento da área vegetada, algo que pode estar relacionado com a criação de diferentes Unidades de Conservação no município. Este trabalho serve como um exemplo de como o geoprocessamento pode ser útil na organização e monitoramento espacial de um município, cidade ou Estado, para determinar os impactos de cada período de expansão ocorrido.
