    In search of a linkage between personality traits and interpersonal behaviour during the covid-19 pandemic: a case study on indian marine engineers using structural equation modelling /
    (Galenos Publishing House, 2024-08-14) Mitra, Toorban
    Building and maintaining social and interpersonal relationships are crucial for mental health. However, due to the unique characteristics of jobs, building and maintaining such interpersonal relationships with colleagues as well as others may not be as similar to off-shore employees like shore- based ones. On the contrary, preference towards exhibiting interpersonal relationship behaviour is another area that needs attention in the maritime sector. Such preferences may be unique while individuals pass through uncertain situations like the coronavirus disease-2019 (COVID-19) pandemic. Against the backdrop of the COVID-19 pandemic, this study investigates the linkages between personality traits and interpersonal relationship behaviours among Indian marine engineers. Data was gathered through snowball sampling from 385 marine engineers utilising the Big Five Inventory and the Fundamental Interpersonal Relationship Orientation-Behavior™ framework after necessary adaptations of these instruments. Results show that conscientiousness is linked to expressed inclusion and wanted control. Extraversion is linked with all behaviours except wanted control, while agreeableness is associated with expressed control. Neuroticism shows linkages with wanted inclusion, expressed control, and wanted control. This study fills critical research gaps by examining the missing links between personality traits and interpersonal relationships in a high-stress environment like the maritime sector and that too during the COVID-19 pandemic. These insights emphasise the need for effective communication and teamwork in high-stress maritime environments.

    Linking leadership integrity - depression, anxiety and stress (DAS) among sailing indian marine engineers during Covid-19 /
    (Universitat Politècnica de Catalunya, 2024-06-01) Mitra, Toorban; Pattanaik, Krushna Mohan
    Modern-day leadership demands competencies to embrace challenges and uncertainties as a part of a working career. Uncertainties bring in many unknown outcomes and a loss of direction to any team. This is much acknowledged when the unknown outcomes are affecting the team spirit and, in turn, organisational sustainability. Leadership integrity is a watershed to handle such uncertainties with positive outcomes. Like in any other business domain, uncertainties are part of the business in shipping. However, there are specific instances in the nature of COVID-19 that came with many challenges, like extended work contracts, no shore leaves, infrequent crew change, quarantine rules before sign-in, online surveys, etc. Such an uncertain and challenging work environment on board a ship (which itself is an organisation) results in anxiety, stress and depression. In this context, leadership integrity provides much-needed direction and can create a healthy work environment in any organisation. It is in this context that this paper tries to measure this hypothesis in an explorative study, particularly among active marine engineers who worked on board ships during the COVID-19 pandemic. Such knowledge facilitates the understanding of organisational behaviour during challenging times and provides a timely prescription for organisational success during uncertainties and challenging times with much significant focus on the integrity of leaders.

    On the design of a compact emergency mechanical ventilator with negative expiratory exit pressure for COVID-19 patients /
    (Taylor & Francis, 2022-07-27) Janardhanan, Sheeja
    The present work deals with the design of a cylinder-piston arrangement to deliver the required tidal volume (TV) of air to the patient through the respiratory tract especially in the setting of severe acute respiratory syndrome corona virus 2 (SARS CoV-2) or corona virus disease (COVID-19). The design ensures that only the desired volume of air is delivered in each breath and a negative pressure is retained at the delivery point in a separate cylinder. The frequency of piston motion is the same as that of the average human respiratory rate (RR). The effect of negative pressure on time of evacuation under the present condition has been verified. The present design provides a compact ventilator unit with a surface area of 0.8 × 0.4 m2 with a minimal power requirement of 116.48 W. An RR of 16 is obtained with a volume flow rate in lit/s by using a twin cylinder arrangement with bore diameter 0.1 m and length 0.4 m. The ratio of inspiration time to expiration time is designed to be 1:2 by controlling the stroke frequency as 16 and piston speed 0.32 m/s. The present design provides promising quantitative information on the design of an automated continuous mechanical ventilator (CMV), which is different from bag mask valve (BMV) operated ventilators, and on preventing and minimising barotrauma.
