The purpose of this exploratory work is to investigate the knowledge of ethics with the perspective of employee in the industry of Pakistan's hospitality. In addition, to start with the ethics by focusing on employee actual experience, not as fixed standards against which everything else is judged, but as a starting point for identifying the knowledge of ethics on which employee are framed their selves and to influence the ever-changing terms of their work-balanced life. For this reason, there comes a time when preliminary studies into the effects of global rules of hospitality necessitated the requirements of Hospitality industry. Nonetheless, to unveil and stimulate awareness of the makings, undoing's, contingencies, and possibilities of global ethics of considerations into the field of hospitality industry of Pakistan. The sampling for the current inspection was taken from the three 4-stars hotel in Pakistan i.e., Serena hotel Islamabad, Nishat hotel Lahore, Grand Faletti's hotel Multan and Pearl continental hotel Faisalabad. The knowledge of rules with the perspective of employee is eventually a new concept and therefore the obtained outcome will open the new horizons for the concrete outcome in future.

“…Several factors for susceptibility to AMS have been identified including a history of previous AMS, the speed of ascent ( Hsu et al, 2015 ; Poudel et al, 2022 ), baseline SpO 2 ( Guo et al, 2014 ; Boos et al, 2016b ), age, sex ( Hou et al, 2019 ), smoking ( Vinnikov et al, 2016a ), obesity ( Ri-Li et al, 2003 ), the studied population (e.g., mine workers) ( Vinnikov et al, 2014 ), and individual susceptibility ( Schneider et al, 2002 ).…”

In the course of their missions or training, alpinists, but also mountain combat forces and mountain security services, professional miners, aircrew, aircraft and glider pilots and helicopter crews are regularly exposed to altitude without oxygen supplementation. At altitude, humans are exposed to systemic environmental hypoxia induced by the decrease in barometric pressure (<1,013 hPa) which decreases the inspired partial pressure of oxygen (PIO2), while the oxygen fraction is constant (equal to approximately 20.9%). Effects of altitude on humans occur gradually and depend on the duration of exposure and the altitude level. From 1,500 m altitude (response threshold), several adaptive responses offset the effects of hypoxia, involving the respiratory and the cardiovascular systems, and the oxygen transport capacity of the blood. Fatigue and cognitive and sensory disorders are usually observed from 2,500 m (threshold of prolonged hypoxia). Above 3,500 m (the threshold for disorders), the effects are not completely compensated and maladaptive responses occur and individuals develop altitude headache or acute altitude illness [Acute Mountain Sickness (AMS)]. The magnitude of effects varies considerably between different physiological systems and exhibits significant inter-individual variability. In addition to comorbidities, the factors of vulnerability are still little known. They can be constitutive (genetic) or circumstantial (sleep deprivation, fatigue, speed of ascent.). In particular, sleep loss, a condition that is often encountered in real-life settings, could have an impact on the physiological and cognitive responses to hypoxia. In this review, we report the current state of knowledge on the impact of sleep loss on responses to environmental hypoxia in humans, with the aim of identifying possible consequences for AMS risk and cognition, as well as the value of behavioral and non-pharmacological countermeasures.

“…People living in low-altitude areas usually develop symptoms of altitude sickness, such as dyspnea. For hastily arrival at high-altitude areas, the incidence rate is approximately ranging from 25% to 85% [3]. At present, the main treatment methods for acute altitude sickness are oxygen inhalation and hyperbaric oxygen therapy.…”

The most severe challenge for troops in a high-altitude environment is hypoxia. Pressure swing adsorption coupled with membrane separation is an ideal solution for oxygen production in high-altitude areas, but the molecular sieve membranes and organic membranes used in this technique are greatly affected by the ambient temperature, humidity, and pressure. Compared with traditional porous materials, metal-organic frameworks (MOFs) have outstanding features such as low densities, large specific surface areas, high crystallinities, and flexible structures. Cr-MIL-101 (MIL: Matérial Institut Lavoisier) and its derivatives are MOFs with high nitrogen adsorption capacities and can be used for oxygen production by air separation. However, since the plateau climate is complex, the applicability of Cr-MIL-101 for oxygen production in high-altitude environments awaits clarification. Therefore, this study constructed a molecular model of Cr-MIL-101, simulated the adsorption equilibrium of N2 and O2 molecules on this material using the grand canonical Monte Carlo (GCMC) method, and obtained their adsorption isotherms and densities. At 298 K and 100 kPa, the maximum adsorption capacities of Cr-MIL-101 for N2 and O2 were 0.94 per cell and 0.23 per cell, respectively. While at 238 K and 100 kPa, the maximum adsorption amounts of Cr-MIL-101 for N2 and O2 were 5.10 and 1.07 per cell, respectively. The thermodynamic parameters and adsorption equilibrium parameters during the adsorption process were analyzed. The conclusion of this study provides theoretical support for optimizing the N2/O2 separation performance of Cr-MIL-101 in high-altitude environments.
