Structural equations modeling was carried out in Smart-PLS 3 in order to test the proposed hypotheses. Results depicted that internal marketing is a significant predictor of internal supply chain integration and this relationship becomes stronger with the intervention of employees’ affective commitment. This study sheds a light on the importance of employees for service organizations and provide a way forward to managers for policy making about their employees in order to develop profitable and competitive assets for the organization
PARK MY RIDE: Your True Parking Companion
Having a smart-phone for the people of any age is common these days. These smart-phones not only provide entertainment to customers but also help them work in a way to make their lives better. In recent times, many daily life problems have been addressed by using smart-phone technology. One of those problems is parking the vehicle. Due to the increase in population and the number of vehicles, the parking issue is getting worst day by day in many big and crowded cities of the world. People have to spend more money and time to find safe parking for their vehicles. The street and roadside parking causes various troubles like fines and damages to the vehicles. So, the paper presented here suggests the best possible solution for parking lots in Pakistan. By using android technology, an android application named “Park My Ride” has been introduced that will help its users to see parking spots near them with the space availability and a complete map navigation to access that parking lot. The administrator panel for parking owners will also help them to manage the booking of vehicles in their parking lots. It would not only save time but also ensures the safety of the vehicles

OBJECTIVES
The way of practising and teaching dentistry has changed significantly worldwide due to the COVID-19 pandemic, and the impact on dental education should not be neglected. Therefore, sharing experiences about online teaching from in-person education is essential to a better learning process during this period. This study aimed to assess the challenges faced by dental students in studying oral pathology online during covid-19: a cross-sectional study.
METHODOLOGY
It was a descriptive cross-sectional study in the Department of oral pathology at Altamash Institute of dental medicine to assess the challenges students faced during the COVID-19 pandemic. A total of 110 participants were approached, and among them, 105 participants responded. Of 105 participants, 78% were females, and 22% were males. Data were analyzed using SPSS version 23.RESULTSAlmost 93.3% of the students felt in-person lectures are more effective than online lectures. Fourth-year students showed higher satisfaction with the number of online tutorial / practical classes taken to provide an in-depth view of the subject than 3rd year students (8.8% vs 91.2%, p=0.045). Fourth-year students showed significantly higher satisfaction with several online theory classes to provide an in-depth view of the subject than 3rd year students (p=0.045).
CONCLUSION
The present study concluded that most students prefer in person classes over virtual learning and face a lack of online interaction with the faculty.
Anaesthetic management of patients undergoing deep brain simulation: A retrospective review of 8 cases from a tertiary care center of Pakistan
Objectives: To review anaesthesia related outcome, perioperative complications and overall length of stay (LOS) in hospital for patients who had deep brain stimulation (DBS).Methods: The study was retrospective review of patients medical records diagnosed with Parkinson disease (PD) and underwent DBS at The Aga Khan University Hospital, Karachi from 2017-2019. Data was reviewed from file notes and patient chart and recorded on predesigned Performa. Frequency and percentages were used to present the data.Results: All patients were anaesthetized using Sleep-Awake-Sleep technique (SAS). Dexmedetomidine was mainly used for conscious sedation. Bispectral index monitor (BIS) was used to monitor the depth of sedation, and kept between 70-85 during sedative phase. All patients had successful intraoperative neurological monitoring, stimulation, and placement of electrodes. Total duration of anesthesia varied significantly in between the patients. Maximum duration was 600 minutes. None of our patient had any intraoperative event related to anaesthetic management. Overall five patients had some adverse events during ward stay. Mean LOS in hospital was four days.Conclusion: Anaesthetic management of DBS is well-tolerated. It requires dedicated team. The SAS technique is excellent for intraoperative neurophysiological monitoring. Careful selection of sedative agents and monitoring depth of anaesthesia using BIS would be beneficial in terms of improving related outcomes
Heuristic antenna selection and precoding for a massive MIMO system
Sixth Generation (6G) transceivers are envisioned to feature massively large antenna arrays compared to its predecessor. This will result in even higher spectral efficiency (SE) and multiplexing gains. However, immense concerns remain about the energy efficiency (EE) of such transceivers. This work focuses on partially connected hybrid architectures, with the primary aim of enhancing the EE of the system. To achieve this objective, the study proposes a combined approach of joint antenna selection and precoding, which holds the potential to further optimize the system’s EE while maintaining a satisfactory SE performance levels. The proposed approach incorporates antenna selection based on a meta-heuristic cyclic binary particle swarm optimization algorithm along with successive interference cancellation-based precoding. The results indicate that the proposed solution, in terms of SE and EE, performs very close to the optimal exhaustive search algorithm. This study also investigates the trade-off between SE and EE in a low and high signal-to-noise ratio (SNR) regimes. The robustness of the proposed scheme is also demonstrated when the channel state information is imperfect. In conclusion, this work presents a lower complexity approach to enhance EE in 6G transceivers while maintaining SE performance and along with a reduction in power consumption
Contingency Analysis of a Power Grid with the Participation of Utility-Scale Solar PV Units: A Case Study from Sarawak, Malaysia
Integrating renewable energy resources (RER)
into the power grid may jeopardize the whole power system if the penetration level or solar PV uncertainty is not thoroughly managed. The critical impact on the behaviour of power system can be observed during the line outage in a power grid connected with large-scale RER. Therefore, contingency analysis (CA) is crucial to assess such hybrid power grid. This paper proposes a framework based on CA to assess the simultaneous effect of large-scale solar photovoltaic (PV) power plants integrated with the existing power grid, particularly, in the aspects of implementing effective measuring indices. Simulation studies have been carried out on a practical power system, which was modelled by considering the probability of solar irradiance at different locations in Sarawak. The study presented in this paper can provide an
insight to identify the level of insecurity for a large-scale deployment of solar PV systems in Sarawak

Objectives: COVID-19 pandemic brought mortalities, morbidities, fear, and financial despair among people around the world. As it advanced, misinformation and myths about it caught wildfire, contributing to misbelief among the already shocked population. Medical students are the building blocks of the medical community and can provide a pivotal role in combating COVID-19 misinformation by delivering correct knowledge and awareness to the non-medical population of the country. Hence, it is important to assess their knowledge and perception of COVID-19 myths. Therefore, this study evaluates medical student\u27s knowledge regarding myths and misinformation related to COVID-19 infection and its vaccine. The study also assesses the belief of medical students on various conspiracy theories of COVID-19.Methods: An online cross-sectional survey was conducted among 401 undergraduate medical students of Karachi in June-August 2021. A validated, structured, and self-administrated questionnaire was used for data collection. The data were entered on an open EPI version 3.01 and Statistical Package of Social Science version 26 for analysis. A chi-square test was performed to identify determinant factors. All p-values less than 0.05 were considered significant.Results: Overall knowledge score of participants about myths and misinformation related to COVID-19 and its vaccine was as follows: 166 (28.9) participants possess good knowledge, while 167 (41.6) and 118 (29.4) had moderate to poor knowledge, respectively. Senior students, vaccinated, and participants infected by COVID-19 had good to moderate knowledge. Overall, 139 (34.7) participants strongly disagree and 103 (25.7) participants somewhat disagree with conspiracy theories related to COVID-19. Absence of belief in the conspiracies is associated with vaccinated participants.Conclusion: The study shows that most medical students possess adequate knowledge of misinformation about COVID-19 and its vaccines, and have low belief in conspiracy theories of COVID-19
