The Inside Story of COVID-19 Pandemic on the Diamond Princess as the prime mover of Present and Future Ship Design
Authors: Arma Gennaro , Peri Angela Denise
Published: August 2022

“…But this coronavirus has forced us into a new framework, within which we move without any ease: everything has new ways, everything appears as never seen, it’s like finding yourself in an uncharted territory…” (G. Arma, 2020) With these words Gennaro Arma, Captain of the Diamond Princess cruise ship, describes the very first moments following the detection of what would become the first recorded outbreak of Covid-19 outside of China. It occurred during a roundtrip cruise which departed from Yokohama port, in Japan, on 20 January 2020. Among the 3,700 people on board, more than 700 tested positive for the virus, 14 of whom died during hospitalization. A situation which was faced without the support of emergency protocols that contemplated a modus operandi to follow. The ship constituted a confined control volume which allowed to analyze the main routes of virus propagation that mainly occur through direct contact between individuals, indirect one via contaminated objects and surfaces (also referred to as fomites) and airborne transmission. This has greatly affected the overall design paradigm, especially concerning the safety levels to be assured on board. The paper is going to analyze these focal points, starting from a possible implementation of HVAC system. It comes after an extensive study of the air flow circulation, as well as the application of filtering and purifications solutions, considering ship age and ventilation type, assessing the possibility of isolating those sectors of the plant acting on some areas dedicated to the management of emergency situations. Synoptically, there will be an extensive analysis related to the different surface types present on board and possible design interventions (i.e. smart materials). The Diamond Princess experience represents the prime mover aimed at the world of scientific research at the formulation of design guidelines applicable to the world of cruise ships and, consequently, in the civil architecture field. The outcome results have helped to build a transversal, holistic know-how, thanks to which it will be possible to control the occurrence of future pandemic episodes.

Published: August 2022

The progressive collapse behavior of a container vessel in pure vertical, horizontal and biaxial bending is determined by nonlinear finite element analyses. A parametric finite element model is used to demonstrate the influence of nonlinear material behavior and welding related imperfections on the ultimate hull girder strength. Convergence for nonlinear static implicit analyses is ensured by using the full Newton-Raphson scheme and the results are validated against Smith’s method.

In recent years the acknowledgement of the relations between the emissions of exhaust gas, in particular CO2, and their effects on climate and environment has grown to a wide level. Many countries and international organizations have begun to work to mitigate the problem and drive the society towards more sustainable sources of energy. Shipping is no exception and in 2018 the IMO – International Maritime Organization set the ambitious goal of reducing the CO2 emissions of the shipping industries of at least 50% within 2050, compared to the levels of 2008. This has introduced the need to research and develop new, sustainable energy sources and power systems for ships. The REShiP projects is aimed to identify a type of ship which would be suitable for an early adoption of a carbon free or carbon neutral fuel and a matching power generation system, tailored on specific routes. A small ferry powered by a hybrid combination of liquid hydrogen-fuelled fuel cells and Lithium-ion batteries has thus been identified. A mathematical model was developed to optimize the usage of fuel cell and batteries based on the ship operative profile. A multi objective optimization was implemented to minimize system performance degradation. To support the mathematical model a 7 kW PEMFC power generating unit was assembled and relevant data have been analysed. Following a regulatory framework research and in lack of comprehensive prescriptive rules, the design of the ferry and the prototype was done in accordance with the alternative design approach based on the risk assessment methodology, reaching a level of confidence appropriate to award an approval in principle.
Fracture Mechanics Properties of Al/Steel Structural Transition Joints for Shipbuilding
Authors: Corigliano Pasqualino , Crupi Vincenzo , Dong Pingsha
Published: August 2022

The need of lowering the weight of ships makes it crucial to have superstructures made of aluminum alloy and the ship hull made of steel. Within this context, the connection between the two different metals becomes crucial as different metals are hardly weldable using traditional techniques. Thus Structural Transition Joints are extremely important. One of the most promising welding techniques is the Explosion Welding process, which reaches a good compromise between weldability and mechanical properties of Structural Transition Joints. In the present study, the mechanical behaviour of Structural Transition Joints made of ASTM A516 structural steel, clad by explosion welding with AA5086 aluminum alloy and provided with an intermediate layer of pure aluminum was investigated. Preliminary fracture mechanics tests on CT Specimens made of Al alloy and shipbuilding grade steel were performed. Afterwards, fracture mechanics properties of the Structural Transition Joint considering a notch located at the interface between the pure aluminum and steel were evaluated experimentally following the current standards. In addition, the Digital Image Correlation technique allowed the analysis of the displacement and strain patterns of the different metals and to evaluate the crack length of the bimetallic specimen.

Digital twins are computational models that replicate the structure, behaviour and overall characteristics of a physical asset in the digital world. In the maritime domain, conventional approaches have relied on mathematical modeling (e.g., linearised equations of motion) and heavy computations for estimating ship resistance and propulsion, seakeeping and maneuverability and overall hull form optimization, treating the vessel as a point body. For instance, the ability to predict a vessel’s future track in confined or congested waters presents a significant challenge due to the fact that as time passes, these models often fall out of sync with their digital counterparts due to changes that happen to the ship (e.g., foulding affecting maneuverability). In addition to this, mostly due to computational resources required, in real world deployments models are simplified, thus reducing their overall prediction accuracy. In our work, we implement AI-enabled coupled abstractions of the asset-twin system, which rely on machine learning methods for constant learning of the evolving over time behavior of a vessel based on historical trip data and information related to vessel’s structure and loading capacity. The evaluation results indicate that the inclusion of vessel and journey specific information is beneficial for the predictions.
TVET Trainers Understanding of Engaging Instruction: Supportive Learning Environment for Work Integrated Learning
Authors: Pirzada Gouhar
Published: August 2022

The purpose of this study is to explore TVET trainers’ understanding of engaging instruction with relevance to ensuring a supportive learning environment that could lead to effective work-integrated learning. Participants’ engagement in the training process that wholly prepares them for real-life work scenarios is always a challenging task for trainers. The existing gaps in theory and practice highlight the significance of the research study. Both the trainees and the trainers are usually not content with the learning environment and the final training outcomes to match their work requirements. This research identifies the trainer’s understanding of engaging instruction under three main themes: supportive learning environment, work-integrated learning, and expected competencies of trainers. Purposive sampling was used to collect data from 21 TVET trainers. All participants are actively working in TVET institutes. The qualitative data analysis technique is applied as a data collection strategy to explore participants' views, opinions, practices, challenges, preferences, and lived experiences. The data analysis revealed that most trainers believe training participants require a conducive environment to enrich their learning experiences. Most participants have also emphasised achieving the work-integrated learning outcomes by applying the KSA (Knowledge, Skills and Attitude) approach. The findings have been discussed from various perspectives, and some suggestions based on results have been put forward, including a further focus on appropriate training strategies.

Published: August 2022

Students’ approaches to the learning process, their learning style, cognitive style, learning preferences, and beliefs about knowledge had been the main focus of empirical research for many years. A quantitative survey was carried out to explore their epistemological beliefs about science and their learning approaches towards science. Moreover, the correlation between these two variables at secondary level science classroom in Chitral, Pakistan was determined. The population of the current study consisted of 59293 students from both genders studying in various public sector schools in Chitral district.  Secondary school science students served as the population for this research, while 379 students were randomly selected as sample. Approaches to Learning Questionnaire (ALQ) and Students Epistemic Beliefs (SEB) questionnaire were adapted and administered for data collection. The findings showed that students employed both surface and deep approaches for science learning at secondary level. Similarly, they possessed mixed epistemological beliefs. Significant correlation was also found between some categories of students’ epistemological beliefs and learning approaches. The current study also discussed the implications of the above findings for teaching and learning activities in the classroom, teacher education institutions, and other stakeholders. Specific recommendations with regards to the nature and assessment of learning were also proposed for classroom practices.

Pemberian pakan komplit yang mengandung limbah pertanian kepada ternak akan meningkatkan utilitas bahan pakan terutama limbah pertanian. Pengawetan dengan cara silase bisa menjadi solusi saat pakan sulit ditemukan di musim kemarau. Silase yang ditambahkan additif akan meningkatkan kualitas fermentasinya. Penelitian ini bertujuan untuk mengkaji pengaruh yang ditimbulkan dari pakan silase pakan komplit dengan aditif fermented juice lactic acid bacteria (FJLB) yang berbeda terhadap imbangan energi dan nitrogen ternak domba lokal. Sebanyak 12 ternak domba lokal jantan dengan bobot badan awal 17,67 ± 1,7 kg (umur 12 bulan) disusun dalam rancangan acak lengkap.  Ransum terdiri dari jerami padi, bungkil kedelai, jagung, dedak padi, pollard dan mineral mix yang disilase menjadi pakan komplit selama 3 minggu. Perlakuan dalam penelitian ini antara lain yaitu T1= Silase tanpa aditif FJLB, T2= Silase dengan aditif FJLB dari Pennisetum purpureum, T3= Silase dengan aditif FJLB dari Pennisetum purpupoides, dengan 4 ulangan tiap perlakuan. Analisis data menggunakan uji ANNOVA. Hasil penelitian menunjukkan bahwa konsumsi energi dan energi tercerna pada T2 lebih rendah dibandingkan dengan control dan T3. Pemberian FJLB memberikan nilai kecernaan energi, energi termetabolisme, dan energi metana yang sama di semua perlakuan. Penambahan aditif FJLB menurunkan konsumsi protein kasar, namun aspek protein kasar tercerna, kecernaan protein kasar, protein kasar termetabolisme, dan allantoin menunjukkan nilai yang sama dengan kontrol. Dapat disimpulkan bahwa perbedaan penambahan aditif FJLB pada silase pakan komplit masih memberikan deposisi energi dan protein yang sama.

2021. február 6-án ünnepeltük a 75. évfordulóját  annak, hogy Bay Zoltán fizikaprofesszor és csapata a  Tungsram kutatólaboratóriumában észlelte a Holdra  bocsátott radarhullámok visszhangját forradalmian új  mérési technikájával. A háború után mostoha  körülmények között elvégzett, világhírű kísérlet a  magyar űrtevékenység és a nemzetközi  radarcsillagászat kezdetét is jelentette. A holdradarkísérletek jelentősége abban állt, hogy ezek  voltak az első természettudományos vizsgálatok,  amelyeket Földön kívüli tárgyon végeztek. Az  égitestekről szerzett ismeretek évezredeken keresztül  kizárólag passzív megfigyeléseken alapultak, de a  mikrohullámú technika lehetővé tette a távoli  objektumok fizikai vizsgálatát is. Tulajdonképpen  ekkor bizonyosodott be, hogy a Hold egy anyagi  jellemzőkkel rendelkező tárgy, jól meghatározható  távolságra a Földtől. Magyarországon jelenleg számos  nemzetközi űripari együttműködési és  kutatási projekt folyik, amelyek évről évre egyre több  jelentős magyar szellemi és technológiai hozzáadott  értéket hoznak létre. Az immáron több mint 75 éves  múlttal büszkélkedő magyar űrkutatás és  űrtevékenység komoly potenciállal rendelkezik. E  tanulmány a magyar űrtevékenység főbb résztvevőit, projektjeit, sikereit és eredményeit kívánja bemutatni  a kezdetektől napjainkig.

Similarly to the separation and development of electricity systems, the golden age of aviation dates back to the last  century. Admittedly, in the beginning, the two technologies  did not have much effect on each other; however, in the  21st century, these two systems in many cases cross each  other’s paths in everyday life, while performing the  operation and maintenance tasks. In this paper, the author  describes how a modern electricity infrastructure is built up  and explains the process used for transferring electric  power generated by the power plants to the consumers. In  addition, this paper familiarises the reader with the procedures and methods allowing to assign more and more functions and tasks to the drone technology and to assure  its efficient integration with certain elements of the energy  system.
Galactosialidosis presenting as non-immune hydrops in a newborn: A case report
Authors: Sharma Anu , Sujatha Radhika , H Sankar V , Neisseril Krishna , Nair Akash
Published: August 2022

Galactosialidosis is a rare autosomal recessive lysosomal storage disorder (LSD). It results from defects in glycoprotein degradation due to mutation in a single gene, encoded by the protective protein cathepsin A, (CTSA), located on chromosome 20q13.12. Most cases of non-immune hydrops fetalis (NIHF) nowadays being recognized are due to cardiac, lymphatic dysplasia, and hematological disorders. Inborn errors of metabolism account for NIHF in 1.3% of patients. Among metabolic disorders, around 14 LSDs have been reported as being associated with NIHF and congenital ascites. In the present case, we report an early infantile form of galactosialidosis with a novel homozygous miss-sense mutation c.319 A>C (p. Ser107 Arg) in exon 3 of CTSA gene in a newborn who presented as non-immune hydrops. The baby also had coarse facies, wide anterior fontanelle, hypertelorism, bilateral congenital talipes equinovarus, hepatosplenomegaly, nephrocalcinosis, and disproportionately small limbs with metaphyseal irregularity. Gradually, he developed worsening cardiac functions and cardiomyopathy and succumbed to death on day 47 of life. Being an autosomal recessive disorder, it can recur in the next pregnancy and treatment is mainly supportive. Targeted prenatal diagnostics in subsequent pregnancies can help in early diagnosis.

Authors: Li Bo , Scott Olan , Sharpe Stirling , Stokowski Sarah , Zhong Qian
Published: August 2022

Abstract: Media coverage of the Winter Olympic Games provides an invaluable opportunity for athletes to promote themselves to a global audience that otherwise would not be reached through regular calendar events. An important element of athlete promotion occurs during press conferences when athletes speak to global media after winning a medal. The purpose of this study was to investigate how Olympic medalists presented themselves in front of the media after achieving Olympic success. A thematic analysis was conducted using press conference transcripts from 307 Olympic medalists during the 2018 PyeongChang Winter Olympic Games. The results indicated that athletes were likely to use media opportunities to self-promote their achievements, share secrets and stories, exhibit gratefulness, protest, show patriotism, and provide expert opinion. Overall, six categories of self-presentation were identified and discussed. Practical and theoretical implications are offered throughout, including a contribution to self-presentation theory and suggestions for athlete media literacy training.

Restoration of critical land so that its products can increase and contribute to the community's welfare is a special challenge at this time. One of the efforts made by the government in overcoming this problem is by carrying out Forest and Land Rehabilitation activities by involving farmers as local workers. This study analyses community participation in forest and land rehabilitation programs in Datar Lebuay Village, Air Naningan District, Tanggamus Regency. The research was conducted in June 2021. Data collection was carried out through interviews, observation, and documentation techniques. Respondents were determined using the Slovin formula with an error limit of 10%. The interview process uses a proportional simple random sampling technique. The data obtained were then analyzed descriptively quantitatively using a Likert scale. The results showed that there was several activities rehabilitation forest, namely: the planning subsystem with field technical design activities had a final value of 3, the implementation subsystem with a seedling, planting, and plant maintenance activities, with each final value of 3, except for plants which had a final value of 4 Monitoring and evaluation subsystem with monitoring and evaluation activities, with a final score of 3. The Forest and Land Rehabilitation (FLR) activities with community participation levels have Ordinary criteria (B). This shows that forest rehabilitation activities involving farmers are implemented correctly so that the land on which farmers are involved in rehabilitation activities is expected to be more sustainable.

Published: August 2022

As intoxicações exógenas são a quarta causa no ranking das internações por acidentes, para a faixa etária de 0 a 14 anos, podendo ser letais dependendo do agente tóxico envolvido. Por não ser a primeira causa de morte infantil, ela pode passar despercebida pelos pais e responsáveis. Diante disso, levantou-se o seguinte problema: quais as causas e consequências da intoxicação exógena infantil em crianças até a segunda infância? Perante o questionamento, o objetivo deste estudo consiste em descrever os métodos, causas e consequências de intoxicação exógena em crianças de zero a nove anos completos; apresentar uma cartilha de orientação aos pais e familiares sobre as precauções, consequências, identificação dos sinais de intoxicação, cuidados e encaminhamentos necessários. A metodologia adotada foi a revisão integrativa de literatura, realizada na Biblioteca Virtual em Saúde e nas bases de dados Literatura Latino-Americana e do Caribe em Ciências da Saúde, Banco de Dados de Enfermagem e Medical Literature Analysis and Retrievel System Online, onde foram selecionados sete artigos, dentre 1.241, publicados de 2011 até 2021, seguindo os critérios acatados no estudo. Como resultado da pesquisa, houve um predomínio de estudos transversais descritivos, onde não demonstraram uniformidade sobre faixa etária, no entanto, predominou o sexo masculino para os acidentes tóxicos, trazendo também os medicamentos como principal método de intoxicação infantil, seguido por produtos de limpeza. Conclusão: os resultados obtidos indicam que as intoxicações exógenas infantis estão correlacionadas aos fatores socioeconômicos, culturais e comportamentais da criança, tanto os descuidos e desconhecimento dos responsáveis. As consequências das intoxicações variam de acordo com a quantidade e toxicidade do produto, podendo levá-las a internações, e em casos mais graves a utilização da Unidade de Terapia Intensiva (UTI), entretanto, poucas evoluem ao óbito. O alerta para os cuidados no armazenamento domiciliar auxilia para a diminuição das consequências referentes à intoxicação exógena nas crianças. As estratégias de prevenções para as famílias como a orientação por meio de materiais educativos é uma medida de conhecimento a serem aplicadas, assim como a intensa divulgação sobre as ocorrências, primeiros socorros e o reconhecimento de sinais e sintomas de uma intoxicação.

Published: August 2022

This paper anticipates trends in the digital economy during a COVID-19 epidemic worldwide. The United States and China are considered the world’s largest economies and have attempted to transition to fully digital economies over the last few years. Therefore, this paper used the auto-regressive integrated moving average (ARIMA) model and the gross domestic product (GDP) for the USA and China over the period 1960-2019. As we arrive at the peak of the COVID-19 pandemic, one of the most squeezing questions confronting us is: How has the COVID-19 crisis affected the USA and China’s GDP growth? The results have shown first that the GDP growth for both years 2020 and 2021 are approximately 6% and 10% for the USA and China, respectively. Second, the COVID-19 pandemic cannot influence the countries that depend on technology and the digital economy. It can be seen that technology is playing a very significant role in our daily life and nations’ economies.

Published: August 2022

Today, the rapid development of technology has also affected the existing learning processes. In addition, this development has made it necessary for children to develop skills by the needs of the 21st century.  In this research, an alternative to the question of how we can support and update learning activities suitable for our age is presented. Digital game-based learning concepts are explained in the light of the literature and suggestions on how to use them from early childhood are presented.  Game is the most important supportive activity for development areas in early childhood. It also similarly affects learning processes. Learning with play makes the child more active and makes him excited about learning. This increases the motivation to learn. According to the research, when DGBL is used effectively, it has been seen that children support many 21st century skills such as critical thinking, problem-solving, and cooperative learning. This review demonstrated the importance of combining learning and game of digital technology used as an education model. In addition, Practical recommendations are presented for using technology in preschool children.

Cases were categorized into three groups according to the timing of HRCT, 10 cases were in early (0-2days), 56 cases in intermediate (3-5days) and 110 cases were in late (6-12days) groups. Chest CT scan images showed bilateral peripheral ground glass opacities 96.63%, pulmonary consolidations 15.9%. Notably 29.54% patient had normal CT scan chest and 60% of them were imaged at early phase. With a longer duration of symptoms, chest CT findings were more typical including GGO, consolidation with greater total lung involvement. Bilateral peripheral GGO was observed in 20% patients at early phase while 53.57% and 64.54% were observed at intermediate and late phase of illness. Among the symptoms cough and dyspnea were observed more related with typical CT changes (95%). Diabetes and Hypertension (58% of patients) were the leading comorbidities that were found related with GGO and other typical CT findings. Mean time duration between symptom onset and positive RT PCR, CT scan changes were 4.79 and 7.55 respectively.
