Assessment of Cybersecurity Risks: Maritime Automated Piloting Process
Authors: Pöyhönen Jouni , Lehto Martti 
Published: March 2022

A modern society is a combination of several critical infrastructures, of which international and national maritime transportation systems are essential parts. Digitalization makes it possible to increase levels of autonomy in maritime systems. It also means fully existing cyberenvironments in maritime processes. In cyberenvironments, it is crucial there is trustable information communication between system elements of the process, alongside the usability, reliability, and integrity of systems data in the operating environment. In order to develop maritime autonomy in Finland the Sea4Value / Fairway (S4VF) research program has been developed. At the first stage of the program, the main goal is to create automated fairway piloting feature in the near future. An automated remote piloting process, “ePilotage,” will be a complex system of systems entity. This paper provides a research approach to investigating the cybersecurity risks at the system levels of process. It emphasizes the importation of comprehensive risk assessment to increase the cybersecurity of fairway operations. The findings of the study are located in cybersecurity risks in critical information flows between the main system blocks of the fairway process. The research question is “How can the cybersecurity risks of automated remote fairway operations be evaluated?” The main findings are related to the probabilities of the risks in all levels of process stakeholders’ responsibilities. Risk assessment methodology, that has been described, is based on attack probabilities against probabilities to defend actions of adversarial in use of communication technologies. Risks assessment factors have been identified and the risk assessment tool have been proposed.
Improving Protection Against Cybersecurity Attacks of Emergency Dispatch Centers

Published: March 2022

Public service answering points (PSAPs), also known as 911 dispatch centers, serve as integral and critical infrastructure components that serves as a conduit between the public and emergency assistance such as police, fire and emergency medical services. It has been demonstrated in previous research, that PSAPs may be exceptionally vulnerable to telephonic and distributed denial of service (TDoS/DDoS) attacks with potentially devastating effects. It is the purpose of this study is to gather the best practices from experts and tap into the knowledge of the professionals tasked with safeguarding PSAPs every day. Due to the unknown full capabilities of the PSAPs and the antiquated infrastructure on which they must operate, it is unclear just what safeguards are in place to defend these critical infrastructure components against attacks of this nature. To gather this information, a multiple rounds qualitative Delphi study was conducted. Through this process, participants were asked to comment on current tactics and techniques, practices that could be implemented under ideal conditions without political or financial hurdles and how to bridge the gap between current and optimal environments. PSAP administrators, hereby referred to as experts, with a minimum of five years of experience working within a United States PSAP were included in this study and provided a firm understanding of their capabilities. The suggestions provided by participants included patch managements, updated hardware, federally mandated standards, regular plan exercises, and standardized education. After gathering and analysing the data, three basic tenets could be appreciated including cyber hygiene, preparedness and intelligence, and education and training. It is expected that the results of this study will prove integral in not only better securing the PSAPs within the United States critical infrastructure, but also understanding some of the hurdles and difficulties PSAP administrators must overcome.
Defending Small Satellites from Malicious Cybersecurity Threats
Authors: Lin Banks , Henry Wayne , Dill Richard 
Published: March 2022

The connection between space and cyberspace domains is increasingly intertwined. Advancements in space technology, decreasing costs for satellite development, and the use of commercial off-the-shelf products present many cybersecurity challenges to space infrastructure. Additionally, space-based global critical infrastructure makes the space domain a prime target for malicious cyber threats. Software-defined radios introduce a potential attack vector for adversaries planning malicious satellite activity. This paper demonstrates how an adversary would send malicious commands via a software-defined radio to affect the integrity of the sensors on the satellite running NASA's core Flight System software. The experiment demonstrates one possible threat vector using a commercially available USRP N210 software-defined radio. The results show that well-constructed messages can be created to manipulate sensors on a target small satellite system. Identifying cybersecurity vulnerabilities like these in space systems can improve security and prevent disruptions for the global space enterprise.

Published: March 2022

Dampak pandemi Covid-19 sangat berpengaruh pada sistem pendidikan di Indonesia. Sistem belajar dituntut untuk menerapkan Pembelajaran jarak jauh (PJJ) padahal sarana dan prasarana di satuan pendidikan tidak serta merta memiliki kualitas yang baik. Khususnya di Kabupaten Kepulauan Mentawai yang termasuk daerah terdepan, terluar, dan tertinggal (3T) yang masih sangat minim akses internet dan perkembangan teknologi yang masih lambat. PJJ di daerah ini merupakan tantangan yang besar dalam penerapannya. Tujuan dilakukannya penelitian ini adalah untuk mengetahui bagaimana penerapan PJJ di daerah minim akses internet pada masa pandemi ini. Penelitian ini adalah penelitian deskriptif, dan data dikumpulkan menggunakan metode observasi, dokumentasi, dan wawancara. Penelitian menunjukkan bahwa PJJ dalam jaringan (daring) yang menjadi alternatif utama yang digunakan di SMA Negeri 1 Siberut Utara adalah Whatsapp. PJJ menggunakan Whatsapp tidak dapat terlaksana secara baik karena minimnya akses internet dan hampir 50% siswa di SMA Negeri 1 Siberut Utara tidak memiliki gawai (smartphone). Dapat diketahui juga bahwa guru dan siswa tidak senang dengan PJJ saat ini yang diakibatkan pandemi Covid-19.
ENSINAR E APRENDER NA EJA
Authors: Costa Sandra Regina Santana , Queiroz Norma Lúcia Neris de , Kunz Sidelmar Alves da Silva 
Published: March 2022

O presente artigo busca refletir sobre o modo de ensinar e aprender dos jovens e adultos no processo de escolarização formal, com vistas à análise de conteúdo de seis artigos publicados em periódicos e comunicações orais apresentados em eventos científicos nacionais, os quais discutem a temática deste artigo. As concepções de aprender e ensinar de professores (as) e educandos (as) são investigadas, tomando como base seis estudos, objeto de estudo deste trabalho. Foram estabelecidos os seguintes objetivos específicos: (i) identificar a conceituação de educação e escolarização; (ii) analisar as concepções de ensinar e aprender dos professores (as) e educandos (as) jovens e adultos da EJA que necessitam se inserir na sociedade; e (iii) analisar as aproximações e os distanciamentos das concepções de ensinar e aprender, preconizadas por Freire e Vigotski nos estudos analisados. Utilizou-se a metodologia de pesquisa qualitativa com a abordagem exploratória, com base no levantamento dos estudos que tratavam da Educação de jovens e adultos, disponíveis no banco de dados do SciELO – Scientific Electronic Library. A análise das informações apoiou-se nas orientações de Bardin (2006). Os resultados apontaram que a educação é reconhecida como um direito subjetivo de todos os brasileiros, inclusive daqueles que não tiveram acesso à educação básica na idade entre os 4 e 17 anos. Esse direito é assegurado pela Constituição Federal (1988) e reafirmado pela LDB (1996). Constatou-se que as concepções de ensinar e aprender são interessantes, mas poderiam ser ainda mais efetivas pelo menos em quatro dos estudos analisados. Percebe-se que há avanços na formação dos docentes para atuar na EJA, mas é preciso, ainda, ampliar essa formação e as pesquisas acerca dessa temática; percebe-se, ainda, a ausência dos sujeitos idosos dos processos educativos, considerando que em nenhum desses estudos se encontram menções a esses sujeitos. Recomenda-se que sejam dadas, ainda, mais vozes aos jovens e adultos nos estudos como participantes de pesquisa.

Carotenoids are tetraterpenoid organic pigments found in plants, bacteria, fungi, and algae, and come in a variety of colours including yellow, orange, red, and pink, fund all of these organisms, carotenoids can be complex lipids and other metabolic components. Carotenoids are used in a variety of ways, including as antioxidants, antibacterial agents, and food additives.The present study included the isolation of bacteria producing carotenoids pigments that isolated from different sources (soil, food and air) in Basrah, Iraq. Results showed, that out of 24 isolates isolated from above sources which can be produce carotenoids. Ten of those isolates were gave the highest productivity of pigments. Morphological, biochemical, and gene investigations were performed on all 10 isolates. The 16SrRNA sequence analysis of all isolates was recorded as new strains and put in the BDDJ Gene Bank, and the phylogenetic tree of the isolates was constructed using MEGA 6 software. Those strains that are the primary screening for carotenoids production.Bacterial isolates were characterized and identified based on phenotypic properties and molecular techniques. five strains, belonging to genera of Plantibacter flavus BKA3, Sphingobacteruim faccium BKA4, Stenotrophomonas pavanii BKA5, Microbacteruim keltanolyticum BKA6, Brachybacteruim muris BKA12, were isolated from soil and four strains, belonging to genera of Kocuria turfanesis BKA8, Kocuria rosea BKA10, Massilia timonae BKA11, were isolated from air, the strain Pseudomonase cani BkA13 and P. fluorescens BKA2, isolated from food. The carotenoid was extracted by methanol solvent and it’s analyzed by spectrophotometric within 400-600nm and wave length maximum was found at 460nm. The results showed the isolate of K. turfanesis BKA8, reached a height of carotenoid content of 753.11g.gm-1 after 72 hours of shaking culture at 150 rpm in nutrient broth at 27˚C, pH 7.

The Mineralogy of Pt-Fe alloys and phase relations in the Pt–Fe binary system
Authors: Cabri Louis J. , Oberthür Thomas , Schumann Dirk 
Published: March 2022

ABSTRACT
A revised Pt–Fe phase diagram is proposed to replace those used in the materials science literature (e.g., Okamoto 2004), and to improve the one of Cabri & Feather (1975) by adding high-temperature phase equilibria data published in the mineralogical literature. The projected solid-solution fields at room temperature in the pure Pt–Fe system lie at the following approximate compositions: for γ(Pt,Fe) from Pt to Pt0.78Fe0.22, for Pt3Fe from Pt3.04Fe0.96 to Pt2.64Fe1.36, for PtFe from Pt1.16Fe0.84 to Pt0.67Fe0.33, and for PtFe3 from Pt1.26Fe2.94 to Pt0.68Fe3.32. The phase relations and phase boundaries are discussed and evaluated for Pt-Fe alloys occurring in pristine intrusive rocks and ores as well as in eluvial and placer deposits derived from the former by physical and chemical weathering over long periods of geologic time. In spite of the variable concentrations of minor and trace elements, the natural Pt-Fe alloy minerals correlate well with phase relations in the pure Pt–Fe binary system.
