P-785 Validation for effectiveness of the virtual reality based simulator for training of Neophyte on oocyte retrieval/ovum pickup

Abstract Study question To evaluate and measure the clinicians’ performance in oocyte pick-up procedures by using a VR based Simulator before they perform procedure on real patients Summary answer Clinicians’ oocyte pick-up performance significantly improved with the virtual reality simulator—evidenced by heightened accuracy, enhanced hand-eye coordination, and reduced procedure time. What is known already Virtual reality simulators hold immense potential in transforming medical training, providing a secure space for neophyte practitioners to repetitively practice procedures without the involvement of live subjects. However, despite their promise, there is a lack of rigorous evaluation regarding the translation of skills acquired on these platforms into improved clinical outcomes, such as oocyte retrieval. A critical need for comprehensive assessments to determine the effectiveness of virtual reality simulators in enhancing real-world clinical skills and ensuring their impact on patient care. Study design, size, duration The study utilized a quasi-experimental design, incorporating a 60-minute theoretical and 45-minute simulator training program for oocyte retrieval. A total of 40 participants were split into two groups, each consisting of 20 individuals, experiencing a 4-hour and 8-hour simulation session. Following the allocated training hours, participants completed questionnaires covering demographics, first impressions of the VR simulator, and its perceived usefulness. Participant performance was subsequently scored after completion of training. Participants/materials, setting, methods Forty neophyte participants, with master’s in Obstetrics- Gynecology, were divided into two groups for simulation training on oocyte pick-up using a virtual reality-based simulator. Performance parameters assessed included the total number of times the vaginal and ovary walls were pierced, the total number of aspirated follicles, remaining follicles, compromised follicles, blood aspiration count, and aspiration efficiency. These metrics aimed to comprehensively evaluate and measure participants’ proficiency in oocyte pick-up procedures using the virtual reality simulator. Main results and the role of chance The results show that training with the virtual reality-based simulator significantly enhanced clinician performance when performing oocyte pick-up. In the second group, there was a significant increase in the percentage of correctly aspirated follicles (77% vs. In the first group, 60% of patients (p < 0.05), while accompanied by a significant decrease in aspirating follicles time (26 s vs. 38 s, p < 0.05). This translated into improved accuracy of performance on the whole (2.77% vs 1.56%, p < 0.05). Furthermore, those in the second group significantly improved their performance time-wise (20s vs. 35s, p < 0.05), although the level of aspirated follicles remained about the same mean number. These improvements are unlikely to be attributed to chance, as the differences observed between the two groups are statistically significant. These findings are also supported by the study design itself, which divided participants according to two teams undergoing various durations of simulation training. The fact that the trends of improvement in speed and accuracy across sessions support the argument against chance also provides additional evidence, suggesting that use of a virtual reality-based simulator has consistent meaningful impact on clinician performance during oocyte retrieval procedures. Limitations, reasons for caution The study’s limitations include a small sample size, a focus on Neophyte participants without expert group involvement, and the absence of more complicated ultrasound cases in oocyte pickup scenarios. Considering, these outcomes are relatively small and highly sensitive to their groups, further research of larger and diverse group is warranted. Wider implications of the findings virtual reality simulators’ has a transformative impact on enhancing clinical competency in oocyte pick-up. The observed improvements in accuracy and efficacy in simulations imply practical implications for real clinical practice. Requirement of extensive studies with diverse participants are crucial, confirming initial positive results and unveiling enduring effects in clinical settings.

Peer support in intensive care unit follow-up: A qualitative evaluation.

Patients formerly admitted to an intensive care unit and their relatives seek information about life after critical illness to understand their symptoms and what to expect as survivors, and they express a desire to talk to others with similar experiences. Various operational models of post-intensive care peer support exist, and studies have reported potential beneficial mechanisms in patients involved in peer support programs. However, most models have not been formally evaluated. To evaluate the content and setting of structured group meetings and explore participants' experiences of meeting peers. A qualitative evaluation combining focused ethnographic observations and semi-structured interviews with 22 participants attending three intensive care unit café meetings in a university hospital. A thematic analysis was conducted using all data collected. Three main themes emerged; 'Accommodating the diversity of patients and relatives', 'A range of possibilities for identification' and 'A newfound community'. Findings indicate that the content, setting and timing of the café meetings were of minor concern for the participants. Patients and relatives should attend together because the consequences of surviving a critical illness affect both. Larger groups of participants appeared to increase the likelihood of encountering broad variances in participants' experiences from the critical illness trajectory. The findings indicate that before attending a meeting, the participants did not find previous experiences sufficient in managing their new life situations and they felt alone in their experiences. Peer support invited participants into a secure community and eased their sense of being alone in their struggles. Meeting peers seemed to be more important than following a specific model of peer support. When setting up peer support for former intensive care patients, the most important aspect is to create a secure space for patients and their relatives to meet.

Extending SysML Model Federation to Support Systems of Systems Multilevel Security Development

AbstractPractitioners of modern systems engineering within the defense industry and intelligence community often find themselves being pulled in diametrically opposed directions. On the one hand, systems engineering is quickly evolving into a digital practice, strategically connecting heterogeneous sets of models to form digital threads and digital twins capable of providing insights more valuable than the sum of their parts. On the other hand, the inherent nature of working within the national security space necessitates information be held a multiple levels of classification, safeguarded from release, and compartmentalized. This paper focuses on Model Based Systems Engineering (MBSE) development to introduce methods and tools to aid in overcoming these challenges. The work presented here builds on previously published works in SysML Model Federation for Systems of Systems (SoS) Architecting, the experience of applying this methodology on real world programs. Furthermore, it leverages freely available MBSE tools, processes, and methods in the construction of System Architecture Models (SAMs). This paper culminates in a call to action for additional published research and development to address residual challenges and gaps with respect to executing MBSE for Multilevel Security (MLS) development.

The Great Game of Space: Space Political Adventurism and Battle for Superpower Status Beyond the Horizons

Wars will not be fought on the grounds in future, but explosions will occur beyond horizons. The subject of advanced strategies of Great Powers, space militarization, and political adventurism of China, USA, and Russia has been extensively inscribed in this research paper. The paper mainly reflects the political stratagem and space arms race of Russia, China, and the USA, which are combating each other for power status in orbits of space. As China and Russia challenge USA dominance in space, the USA seeks to weaponize space to maintain its supremacy and counter these rivals. The evolving international structure and world order are steering warfare into new dimensions, with space militarization posing nontraditional security threats like spying, surveillance, space debris, and satellite destruction. Technology has advanced to the point where states have developed sophisticated spy satellites and anti-satellite weapons capable of targeting other satellites from space or the ground. Despite international legal efforts and multilateral cooperation, major powers continue to expand their space arsenals, creating national security concerns. The study argues that international institutions have failed to curb the space arms race due to their ineffectiveness. Thus, there is a need for a shift in focus to find common ground and resolve this space security conflict. The paper provides a theoretical overview of the role of international institutions and state behavior in the international system. Using qualitative research techniques, the study conducts in-depth exploration through secondary data gathered from various articles, journals, reports, vlogs, videos, and magazines. Descriptive and explanatory research approaches are employed to achieve the research objectives.

Understanding the Sociocultural Dynamics of Loneliness in Southern Spanish Youth

Loneliness among young people has been increasing in recent years and is considered a major public health problem. This article delves into the sociocultural dynamics that favour the experiences of loneliness. For this purpose, 40 students between 19 and 24 years of age were interviewed using the photo elicitation interview (PEI) strategy. The results show a gradual normalization of the experience of loneliness and an effort to become accustomed to it. Virtual relationships and isolation linked to the COVID-19 pandemic are considered the two factors that have most enabled a climate prone to loneliness. Young people identify a few elements that feed social loneliness, such as an understanding of instrumental relationships, a scarcity of intimate relationships, a demand for hyperconnectivity, a fantasy of independence and a culture of positivity that hinders the establishment of quality social ties. Faced with hostile relational conditions, youth are sent into a cycle of loneliness. The greater the distrust of the environment is, the greater the defensive reactions and social distancing, and the greater the search for nearby spaces of refuge, security and shelter. Social withdrawal makes in-person relationships difficult and strengthens the need to isolate and become accustomed to loneliness.

A Multi-Satellite Space Environment Risk Prediction and Real-Time Warning System for Satellite Safety Management

In response to the need for a space security situation assessment during orbit, the multi-satellite space environmental risk prediction and early warning system is based on the detection results of the space weather payload of the Fengyun 4A and 4B satellites, as well as the prediction results of the National Space Weather Center, for the first time. By comprehensively utilizing some open-source data, it is the first time that we have achieved a 24 h advanced prediction of the space environment high-energy proton, low-energy particle, and high-energy electron risks for the safety of the Fengyun-series high-orbit satellites, and a real-time warning of satellite single-event upset, surface charging, and deep charging risks. The automation system has preliminarily achieved an intelligent space risk assessment for the safety of multiple stationary meteorological satellites, effectively improving the application efficiency of the space environmental data and the products of Fengyun-series satellites. The business status is stable in operation, and the resulting error between the predicted results of various risk indices and the measured data was less than one level. The warning accuracy was better than 90%. This article uses the system for the first time, to use Fengyun satellite data to, accurately and in a timely manner, predict and warn us about the low-energy particles and surface charging high-risk levels of the Fengyun 4A and 4B satellites during the typical space weather event on 21 April 2023, in response to the impact of complex spatial environmental factors on the safety of Fengyun-series high-orbit satellites. The construction and operation of a multi-satellite space environmental risk prediction and early warning system can provide a reference for the safety work of subsequent satellite ground system operations.

The Right to Defend the Homeland v. the Duty to Defend the Homeland

The central issue in the context of the russo-ukrainian war due to the aggression of the Russian Federation is the interpretation of whether it should be interpreted as the right to defense or as the duty to defend the Motherland. The problem seems to be understudied in the literature, although in fact it is revealed in considerable detail from the point of view of national security and extraordinary protection of the constitution. The article reveals the structure of the right to defend the Homeland in the context of existential threats to the Ukrainian nation through the lens of positive duties of the State and the principle of republicanism as the basis for joint activities of citizens. The author proposes an approach to resolving the dilemma of the right/obligation to defend the Homeland as ensuring the security space of free citizens and identifies the main components of the subjective public right to defend the Homeland and the obligations of the State which correspond to it. The structure of the right to defence of the Homeland consists of a set of institutional and procedural means of ensuring Ukraine’s defence capability as a security space for citizens who exercise their right to defend Ukraine, and the State’s obligations to 1) keeping records of the population capable of performing functions of defending the Motherland; 2) organizing military training and teaching tactical medicine to citizens; 3) providing the population with military ammunition and their effective administration; 4) organizing the controllability of the national defence system in the event of a military The notion of defence of the Homeland as the right to resist despotism and aggression is crucial in understanding the structure of the responsibilities of the State of Ukraine and the corresponding joint activities of citizens to implement systematic measures to build an effective defence capability of the nation and the State. Building up the territorial defence forces makes it possible to quickly deploy military units in case of an enemy troop breakthrough into the rear of the national territory and provide them with a worthy response, destroying enemy military units and conducting adequate retaliatory operations.

Evaluation of Sustainable Maintenance and Security of Green Spaces in Public Housing Schemes in Lagos State, Nigeria

Security of lives and property in housing environments is one of the basic necessity in the provision of public housing. The nature of maintenance given to green spaces in public housing environment can affect the level of security of lives and property. However, due to the antecedents of public housing, its unique population and the problems it creates for law enforcement agencies on security issues, there is need to evaluate how sustainable maintenance of green spaces within public housing could affect the level of security of lives and property. The public housing constructed by the Lagos State Development and Property Corporation (LSDPC) in Lagos State, Nigeria was used for this study. Primary data was collected from 1036 housing units in 12 different estates of the LSDPC in Lagos State, using the research tools of the questionnaire and structured observation schedule. Descriptive statistics and categorical regression analyses were carried out on the data. The results showed that the green spaces around each housing units were sustainably maintained, than jointly owned green spaces by all residents of the housing estates and this has implications to the level of security of lives and property in the housing estates. It is recommended that public housing estate’s green spaces be designed to allow for sustainability in maintenance by each housing units, which would lead to a general sustainable maintenance view of all green spaces available in the public housing environment.

Innovating Deterrence Strategies in the New Space Age

In recent decades, space has become a crucial arena in international relations, reshaping geopolitical dynamics due to the increased reliance on satellite technology and strategic space assets. Nations globally recognize the economic and strategic advantages of space, leading to cooperation and competition. The expanding use of space for communication, navigation, surveillance, and exploration has become integral to modern societies. The commercial space industry, driven by private entities, contributes significantly to space endeavors. This heightened reliance on space assets necessitates robust space security policies to protect critical systems and maintain technological advantages. Traditionally, deterrence theories focused on terrestrial domains, but the unique characteristics of space demand a paradigm shift. The article introduces a novel perspective on space deterrence, emphasizing strategic capabilities, alliances, and a nuanced understanding of potential aggressors. Core components include denial, resilience, and cost imposition strategies. Military strength, alliances, and space-based nuclear assets play roles in conventional and nuclear space deterrence. Dissuading military aggression involves operational concepts, resilience, and strategic costs. Shaping aggressor thinking requires perception management, confidence-building, and norms. Crafting denial and punishment strategies involves arms control initiatives. Understanding potential aggressors involves assessing motives, aligning interests, and evaluating orbital escalation. The multidimensional nature of space deterrence converges to create a robust framework for dissuading aggression, ensuring a stable and secure celestial environment.

Ngajeng Wong Kalang yard, in harmony with nature: Ethnographic approach in Kalang Village, Lumansari Village, Gemuh District, Kendal Regency - Central Java

Pekarangan ngajeng (Ngajeng yard) is an open area at the front of the residence. Ngajeng yards are formed based on the division of residential land. The formation of the Ngajeng yard is based on tradition. The Ngajeng yard's use is determined by social, religious, traditional, and agricultural factors. The ngajeng yard is still preserved by the Kalang village's Javanese sub-ethnic group, the Kalang. The advantage of the ngajeng yard space as a path for the sun's movement is provided by the Limasap house, where the Kalang people reside, being oriented towards the North and South. Specifically, the objective of the ngajeng yard following the direction of the sun's movement will be covered in this research. The methods used are 1) ethnography, describing traditions related to the Ngajeng yard as well as religious aspects and beliefs of the Kalang people; 2) Analysis of the sun's movement in the East to West trajectory. The orientation of the traditional Limasap omah (house) building influences the existence of the ngajeng yard; 3) The next stage is looking for a belief system through ontology, explanation, prediction, axiology, practice, and epistemology approaches. At this stage, a belief system about the Ngajeng yard is obtained. Thus, it can be concluded that the Ngajeng yard is an open space that has various functions for the Kalang people. These functions are 1) Social function, as a communication, mitigation, and security space; 2) The function of tradition, as a space for the obong tradition to lead ancestors to nirvana; 3) Agricultural function, related to tandur (planting) traditions and harvest traditions. The belief system that is formed is a legacy of tradition related to the implementation of the wong (people) Kalang tradition.

Research on the Evolution Trend of Group Psychological Security Risks Under Public Health Emergencies: Mining and Analysis Based on Social Media Data.

In the digital age, people's attitudes and psychological security towards public health emergencies will be shared. Similar or identical psychological security states are prone to clustering and differentiation, while differentiated group psychological security is more prone to polarization, leading to group psychological security risks and then posing a threat to social stability and national security. However, existing studies mostly use qualitative analysis methods to study group emotional risks. There are still limitations in the study of dynamics of group psychological security risks through mining real data of social media. The study aims to use intelligent analysis methods to understand how group psychological security risks dynamically change. The study draws on text sentiment analysis, Markov chains and time series analysis to construct a framework for the evolution of group psychological security risks. Based on this framework, text data was crawled on Sina Weibo platform, mainly consisting of posts during public health emergencies (March 1st to June 30th, 2022) in Shanghai, and a psychological security lexicon in the field of public health emergencies was constructed. This laid the foundation for identifying the tendencies, intensity, and transitions of individual text psychological security, and then exploring the evolution trend of group psychological security risks. Compared with the generation and reduction periods, group psychological security risks are more likely to occur during the outbreak and recovery periods, and the intensity level is also higher. The overall intensity of group psychological security risks shows an evolution trend of first increasing, then decreasing, and then increasing again. The paper provides an opportunity to explore the dynamics of psychological security in the digital space. Meanwhile, we call on the government and relevant management departments to pay more attention to the group psychological security risks formed during the outbreak and recovery periods of public health emergencies, and take corresponding measures in a timely manner to guide the public to transform the extreme psychological security state into the normal psychological security state, in order to prevent and resolve group psychological security risks, promote social stability and national security.
