Nurses Perceptions regarding Current Skills in Minimizing Patient Aggression at a selected Psychiatric hospital in Lesotho

Background: Meta-analysis of international literature indicate high frequencies of aggression in a mental health setting. Several studies indicate that among professional health workers, nurses are more likely than other staff members to experience aggressive incidences from patients. Furthermore, based on cause, nurses apply a range of interventions in managing aggression, however, despite the perceived value of their intervention in managing aggression, no single intervention is sufficient for handling aggressive patients to stay in control in wards. Despite high priority placed on patient aggression management, insufficient research studies have been conducted on nurses perceptions regarding current skills in minimizing patient aggression. Objectives: The purpose of the study was to describe nurses perceptions regarding current assessment skills in minimizing patient aggression at a selected Psychiatric hospital. Methodology: Non-experimental, exploratory, descriptive research design was used to guide the research process. An all-inclusive sampling method was used with 119 nurses as respondents. Data was collected by means of a questionnaire, analyzed using SPSS version 25. Descriptive statistics procedure was used to present the findings of the study. Results: A minority of respondents, (n=27) 22.7% agreed that their current assessment skills for minimizing patients aggression were good compared to the majority of respondents, (n=92) 77.3%, who expressed a different opinion. This suggests that there are limited current assessment skills in identifying high-risk aggressive patients in a selected Psychiatric hospital. Conclusion: The findings of the study indicate that there are limited current assessment skills in minimizing patients aggression at selected Psychiatric hospital. Therefore, there is a need to provide comprehensive information on nurses current skills in minimizing patients aggression to obtain richer information.

Modular automation cabinet for proactive monitoring in ATEX Zone 2

The paper presents an automation system dedicated to oil & gas machinery applications, such as electrical gas compressors. The future aim is to introduce it into the Romanian oil & gas industry. The system consists of a low size cabinet and its dependencies, which can be used in ATEX Zone 2. The electronic equipment is dimensioned and chosen according to the standards in force, so that the limited current and voltage requirements for methane gas to be met. The key feature is that this system complies with all ATEX standards for Zone 2. Moreover, it can also be a mobile and modular solution if needed, for a versatile and easy use in proactive monitoring of multiple locations across various compressor plants. The design, wireless transmission and possible implementation of this cabinet are presented. Remote data transmission via Wi-Fi and RS-485 communication interfaces between the devices is considered, due to several advantages: mobility, versatility, wide compatibility, environmentally friendly, as well as higher resources efficiency (reducing time and costs).

Performance Improvement Strategies for Discrete Wide Bandgap Devices: A Systematic Review

Wide bandgap (WBG) devices are becoming increasingly popular due to their excellent material properties. WBG devices are commercially available in discrete and module packages. Many studies have investigated the design, structure and benefits of module packages. However, a comprehensive and in-depth overview of the discrete package is lacking. Discrete package has the advantages of flexibility, scalability and reduced cost; however, challenges of severe switching oscillations and limited current capacity are associated with it. This review encompasses the switching oscillations and limited current capacity issues of discrete devices. Switching oscillations are categorized in terms of voltage. The underlying oscillation mechanisms are explored in detail. For the current imbalance, the types, root causes and adverse effects in parallel-connected discrete devices application are reviewed. Besides, the most recent techniques to extract stray parameters are also explored. Finally, state-of-the-art methods to mitigate the switching oscillations and the current imbalance are summarized and evaluated. The performance improvement strategies discussed in this paper can assist researchers to better use the discrete package and can stimulate them to come up with new solutions.
