Desktop as a Service using Local Computers

Abstract: Desktop-as-a-Service (DaaS) has gained prominence as a cloud-based solution for delivering desktop environments to users. However, traditional DaaS models often rely on remote data centers, posing concerns regarding data security, latency, and dependence on external infrastructure. In this paper, we propose a paradigm shift by introducing a novel approach to DaaS that leverages the untapped potential of local computing resources.Our system harnesses the idle computing power available within the user's local environment, including desktops, laptops, and servers, to create a distributed DaaS platform. By integrating virtualization technologies and dynamic resource allocation strategies, we enable the provisioning of desktop environments ondemand, effectively reducing the reliance on centralized data centers. Key components of our system include a centralized management platform for orchestrating resource allocation and workload distribution, virtualization techniques for isolating and managing desktop instances, and robust security measures to safeguard sensitive data. Through experimental validation, we demonstrate the feasibility and performance of our approach, showcasing improvements in data privacy, latency reduction, and resource utilization compared to traditional DaaS models. Our research presents a significant step towards decentralized and resilient computing ecosystems, offering users greater control over their desktop environments while maintaining the scalability and accessibility inherent to DaaS paradigms

Information interaction and partial growth-based multi-population growable genetic algorithm for multi-dimensional resources utilization optimization of cloud computing

Optimizing multi-dimensional resource utilization is a critical research area in distributed computing, particularly in cloud computing, where various heterogeneous resources are integrated to offer a wide range of services. Addressing this issue necessitates the simultaneous consideration of multiple resource bottlenecks. This paper presents a new solution, called the Multi-Population Growth Genetic Algorithm (MPGGA), which consists of a central management unit responsible for executing information interaction and growth quota reallocation, and multiple population evolution executors to perform crossover and regeneration within each population. The proposed MPGGA combines elite sharing and priority support for the weaker population (ESPW), resulting in better convergence and optimality than other combinations of strategies. This outcome is corroborated by extensive ablation experiments on various strategies. Furthermore, the experimental results for minimizing the maximum utilization of resources in each dimension indicate that MPGGA-ESPW outperforms other popular algorithms, such as GHW-NSGA II (1.363x), GHW-MOEA/D (1.339x), NSGA II (1.948x), and MOEA/D (2.151x) in terms of convergence speed. For energy consumption-related optimization problems, the experimental results demonstrate that the adaptability of a single algorithm in MPGGA family is limited by the algorithm of growth route, while also showing that the MPGGA framework is flexible to allow various algorithms as its growth route to adapt to various scenarios.

Implementation of Religious Moderation at Wahid Hasyim University

Higher Education (PT) as a provider of higher education has an important role in efforts to implement religious moderation, unfortunately, in recent years universities have become fertile fields for regeneration of groups that seek to undermine the existence of the Unitary State of the Republic of Indonesia (NKRI). In its implementation, the Ministry of Religious Affairs established a Moderation House in PTKIN, while in PTU there has been no special attention related to this. In particular, this study aims to find out the concept of implementing diverse moderation in Unwahas, which is a PTU under the auspices of the Ministry of Education and Culture of Research and Technology. This research is a qualitative research using data collection including documents, interviews, and observations. This study found that the implementation of religious moderation at Wahid Hasyim University was carried out in at least two strategic steps, namely through structured and academic programs. The structured program is a program that has been planned and implemented by the Aswaja Center Management and Young Aswaja Activists, Wahid Hasyim University, while academic means through the curriculum of the General Basic Course (MKDU), implemented in the Semester Learning Plan (RPS) of Islamic Religious Education Courses, to Aswajaan, Pancasila and Citizenship and also Compulsory Curriculum Courses (MKWK).

Improvement of Personnel, Education and Working Environments via Surveying the Status of Personnel in 119 Emergency Operation Centers

Excluding the Sejong Fire Department Headquarters, visitations to 119 emergency operations centers in 17 cities and provinces across the country were conducted as of 2022 to assess the improvements in personnel arrangements, scope of work, and status of education and training after the placement of situation rooms. On-site visitations were conducted to 119 emergency operation centers in Seoul and 119 emergency operation centers in Busan. Interviews with security personnel participating in the study, such as emergency operation center managers and team leaders, were conducted at the 119 functional emergency operation centers. The status of the deployment, personnel matters, education and training in the operations center, and working conditions were assessed. The following improvements were suggested: The 119 emergency operation centers must be designated as heavy duty departments, provide personnel with the same or higher points as other departments, and provide training and comprehensive evaluation using common practice and simulations on the 119 Emergency Management Standard Response Manual of the National Fire Agency. In addition, working conditions, such as additional personnel points related to promotions, resolution of malicious complaints, difficulty adapting to sleep patterns, the need for psychological treatment, and lack of manpower, must be improved. The results suggest the benefits of operating 112 police emergency operation centers must be introduced.

Caught in a standstill—The unresolved challenges of integrated service delivery in public organizations

AbstractDespite widespread support for integrated service delivery (ISD), the challenges of making ISD a sustainable feature of the public sector remain unresolved. This article offers new insights to this persistent challenge by developing a novel theoretical framework, inspired by the perspective of institutional complexity, and applying it to the case of Danish job centers. We demonstrate how the contradictory and layered nature of governance arrangements simultaneously pose demands of service integration and ‐separation on the job centers. Consequently, the job center managers can neither prioritize one of the demands nor blend them into hybrid practices. Instead, their attempts to further ISD remain inherently temporary—as they are continuously forced to reverse back to old organizational boundaries, to oscillate between work processes supporting service integration and service separation, and to rebuild collaborative relations. The managers are thus caught in a “frenetic standstill,” which hinders the sustainable organizing of ISD.

Theoretical Framework for Virtual Logistics Centers Creation

Intermodal terminals and warehouses operate in different countries and deliver specific services to their customers. For many clients, it is important to receive a full set of the logistics services delivered by a single operator. However, individual intermodal terminals and warehouses may face challenges with providing these services, e.g., just-in-time goods delivery, goods distribution, cargo handling in non-standard situations, and others. In such cases, the cooperation between logistics companies may be required to organize the comprehensive service of cargo within supply chains. One of the possible solutions is to integrate transport and logistics services providers, establishing their cooperation within one virtual logistics center. The aim of this article is to justify theoretically the possibility of creating such a center by combining services performed by the intermodal terminals and warehouses already in operation under a single entity, in order to minimize the cost of logistics services and the time of goods delivery, as well as to create a comprehensive range of logistics services needed by customers. The relevance of the article and the novelty of the idea are associated with justification of the possibility of combining the activities of intermodal terminals and warehouses located separately in the region in order to improve the logistical service of customers. The theoretical basis for creating a virtual logistics center is based on graph theory methods. The article presents a theoretical model, based on a system of edges and vertices of the graph tree, which corresponds to the activities performed by separately located intermodal terminals and individual warehouses. The discussion is focused on the current problems of creating virtual logistics centers. The research results may be interesting for the managers of intermodal terminals, warehouses, and logistics centers, as well as other decision-makers involved in supply chains implementation and development.

Clinical Profile of Acute Poisoning Cases at a Tertiary Care Hospital in Kashmir, India: A Descriptive Cross Sectional Study

Acute poisoning from a variety of substances is common in every part of the world. The sooner the initial resuscitation, decontamination, and use of specific antidotes, the better the outcome. The main objective of this study was to describe the clinical profile and outcome of poisoning cases admitted to SKIMS Medical college, a tertiary care hospital located in central part of Jammu and Kashmir India. Descriptive cross sectional evaluations were conducted on all cases that were admitted to the hospital’s emergency room over a period of one year from March 2022 to February 2023. The following parameters were examined using data taken from hospital medical records: socioeconomic factors, substances consumed, routes of intake, clinical symptomatology and severity of poisoning.300 patients were included in the study with different poisonings of which 35% were males and 65% were females. The most common form of poisoning was due to pesticides followed by rodenticides and opioid intoxication respectively. Majority of the patients had suicidal intent followed by accidental ingestion reported mainly in children. Few patient required intensive care admissions rest all were managed in general ward depicting mild severity of poisoning in majority of the patients. Three patients were brought dead to hospital secondary to opoid overdose and one patient died in hospital who had pesticide ingestion complicated by ventilator associated pneumonia. The less mortality in this study was likely due to mild severity of poisoning, early gut lavage and easy access to hospital. The effects of poisoning on the human body are negative regardless of the agents or method used and this has an impact on the treatment and outcome. Due consideration must be given to clinical, toxicological and epidemiological profiles. Therefore precise and prompt diagnosis, adequate treatment and effective preventative efforts are required. This study highlighted the importance of awareness and for the establishment of poison information centre for the better management and prevention of all poisoning cases.

Anaesthesia praCtice for Caesarean dElivery Snapshot Study (ACCESS): Protocol and baseline characteristics of registered centres.

Specific guidelines to manage caesarean delivery anaesthesia are lacking. A European multicentre study, ACCESS investigates caesarean delivery anaesthesia management in European centres. In order to identify ACCESS participating centres, a registration survey was created. The aim of the current report is to describe the characteristics of ACCESS study participating centres, the rationale for the ACCESS study and the study methodology. The ACCESS study is a European multicentre cross-sectional study to describe anaesthesia management for caesarean delivery (CD) using a snapshot (2-week) design. The ACCESS registration survey gathered: contact details for National Coordinators (NC); Lead Investigators (LI) per centre; centre annual CD volume; expected no. of CD during 2-week snapshot window; centre practice information; data collection language. The ACCESS registration survey was launched July 2022 (Google Forms, Google Inc., Mountain View, CA, USA) and distributed through personal connections, national and international societies, social media networks, during Euroanaesthesia 2023, through the European Society of Anaesthesiology and Intensive Care newsletter. The ACCESS registration survey identified Lead Investigators for 418 centres, in 32 countries, representing an anticipated number of 15,073 CD cases over the planned 12-month study period. A median (range) of 20 (2 to 400) CD cases are anticipated per centre during the 2-week snapshot window. Most 366/418 (87.6%) centres are small, ≤2000 annual CD cases, 42 are medium 2000-5000 cases and 10 are large, ≥5000 annual CD cases. Registered centres reported in 134 (32.0%) centres that anaesthesia for caesarean delivery is performed mostly by a specialist obstetric anaesthesiologist. The ACCESS registration survey revealed variability in volume and CD practice as well as training-levels and staffing among European countries. The ACCESS study (https://www.access-study.org/) aims to generate practice data to guide CD anaesthetic management strategies.

Nationwide Incidence and Trends in Central Retinal Arterial Occlusion Management: A 5000-Patient Analysis.

Central retinal artery occlusion (CRAO) is a rare and visually debilitating vascular condition characterized by sudden and severe vision loss. CRAO is a compelling target for intravenous alteplase (tPA) and endovascular mechanical thrombectomy (MT) due to pathophysiological similarities with acute ischemic stroke; however, the utility of these interventions in CRAO remains dubious due to limited sample sizes and potential risks. To assess usage and outcomes of tPA and MT in CRAO, we queried the National Inpatient Sample database using International Classification of Disease, Ninth and Tenth edition for patients with CRAO and acute ischemic stroke between 2010 and 2019. Our cohort of 5009 CRAO patients were younger with higher rates of obesity, hypertension, long-term anticoagulant use, and tobacco use compared to acute ischemic stroke patients. CRAO patients had lower rates of tPA administration (3.41% vs 6.21%) and endovascular MT (0.38% vs 1.31%) but fewer complications, including deep vein thrombosis, pneumonia, urinary tract infection, acute kidney injury, and acute myocardial infarction (all P < 0.01). CRAO patients had lower rates of poor functional outcome (31.74% vs 58.1%) and in-hospital mortality (1.2% vs 5.64%), but higher rates of profound blindness (9.24% vs 0.58%). A multivariate regression showed no relationship between tPA and MT and profound blindness, although the limited sample size of patients receiving interventions may have contributed to this apparent insignificance. Further investigation of larger patient cohorts and alternative treatment modalities could provide valuable insights for revascularization therapies in CRAO to optimize visual restoration and clinical outcomes.

Influence of PTFE content on structural parameters of microporous layer and its performance in PEMFCs

The gas diffusion layer (GDL) is the water management center of proton exchange membrane fuel cells (PEMFCs), and the composition and structural parameters of this microporous layer (MPL) seriously affect the performance of fuel cells. Herein, a three-dimensional model of MPL structure, with different PTFE contents, is established based on the close-packed structure model, and the concept of critical pigment volume concentration(CPVC) during the coating process is introduced to elucidate what. The porosity of MPL with different PTFE contents is calculated by using the di-n-butyl phthalate (DBP) absorption number of Vulcan XC-72 and compared with the experimental values. The influence of PTFE content and structural parameters on the performance of a single cell is analyzed based on the porosity, surface morphology, water and gas permeabilities, hydrophilicity, hydrophobicity and surface resistivity of MPLs with different PTFE contents. The optimal PTFE content in MPL is determined to be 20–30%, and the maximum power density of a single cell is achieved to be 1.55 W/cm2.

Physical examination a boon-racoon eyes in a child with neuroblastoma

Metastatic neuroblastoma often presents with prolonged fever, cytopenias and significant constitutional symptoms, before the abdominal mass is evident clinically. Clues like subcutaneous nodules and racoon eyes can help a clinician to suspect and evaluate appropriately to arrive at a timely diagnosis. We report a 3-year-old girl who had prolonged fever and constitutional symptoms for more than 2 weeks. On evaluation in outpatient visits, child was found to have cytopenia, hence was referred to our center for further management. Clinical examination revealed raccoon eyes with scalp nodules, hepatomegaly and abdominal mass predominantly over left lumbar area crossing over midline. On further investigations including radiological imaging and bone marrow biopsy child was diagnosed with metastatic neuroblastoma. Metastatic neuroblastoma often presents with prolonged fever, cytopenias and significant constitutional symptoms, before the abdominal mass is evident clinically. Clues like subcutaneous nodules and racoon eyes can help a clinician to suspect and evaluate appropriately to arrive at a timely diagnosis.

Prevalence of high-risk human papillomavirus infection among women with diabetes mellitus in Accra, Ghana

BackgroundThere is increasing evidence of a higher risk and poorer prognosis of cervical cancer among women with diabetes mellitus (DM) compared to the general population. These are mediated by higher susceptibility to persistent high-risk human papillomavirus (hr-HPV) infection due to dysfunctional clearance in an immunocompromised state. We aimed to determine the prevalence of hr-HPV infection and cervical lesions in a cohort of women with DM in Ghana. We further disaggregated the prevalence according to DM type and explored factors associated with hr-HPV infection.MethodsThis retrospective descriptive cross-sectional study assessed 198 women with DM who underwent cervical screening via concurrent hr-HPV DNA testing and visual inspection with acetic acid in an outpatient department of the National Diabetes Management and Research Centre in Korle-Bu Teaching Hospital, Accra from March to May 2022. Univariate and multivariable binary logistic regression were used to explore factors associated with hr-HPV positivity.ResultsAmong 198 women with DM (mean age, 60.2 ± 12.1 years), the overall hr-HPV prevalence rate was 21.7% (95% CI, 16.1–28.1), disaggregated as 1.5% (95% CI, 0.3–4.4) each for HPV16 and HPV18 and 20.7% (95% CI, 15.3–27.0) for other HPV genotype(s). Respective hr-HPV prevalence rates were 37.5% (95% CI, 15.2–64.6) for type 1 DM, 19.8% (95% CI, 13.9–26.7) for type 2 DM, and 25.0% (95% CI, 8.7–49.1) for unspecified/other DM types. Past use of the combined contraceptive pill independently increased the risk of hr-HPV infection by approximately three times (adjusted odds ratio [aOR] = 2.98; 95% CI, 1.03 − 8.64; p-value = 0.045), whereas each unit increase in FBG level increased the odds of hr-HPV infection by about 15% (aOR = 1.15; 95% CI, 1.02 − 1.30; p-value = 0.021).ConclusionOur study points to a high prevalence of hr-HPV among women with DM and highlights a need for glycemic control among them as this could contribute to lowering their odds of hr-HPV infection. The low overall rates of HPV vaccination and prior screening also indicate a need to build capacity and expand the scope of education and services offered to women with DM as regards cervical precancer screening.

Актуальные проблемы внутрисистемного взаимодействия федеральных органов исполнительной власти

One of the directions of improving the activities of executive bodies is associated with the construction of an effective organizational and legal model of their intra-system interaction. At the federal level, this task is special significance because of the national importance of the management decisions taken. The dichotomous legal nature of the interdepartmental interaction system of federal executive bodies is due to the subordinate regulatory regulations of its organization. Legislative gaps and uncertainties in the legal status of the unified management center of this system, the Government of the Russian Federation, devalues the preparation and implementation of strategic planning measures by federal executive bodies. An equally significant problem is the absence of a unified digital platform for interdepartmental interaction, which makes it possible to speed up and streamline direct and feedback communications between bodies and officials.

Quality 5.0: Towards sustainable quality improvement in organizations

&#x0D; &#x0D; &#x0D; The concept of Quality 5.0 in management sciences has emerged relatively recently. It is an attempt to respond to the limitations attributed to Quality 4.0, which focuses on industry and the use of advanced technologies mainly in production processes. Quality 5.0 goes beyond this framework and introduces an equally strong human and social factor. The article defines the concept of Quality 5.0 in relation to quality improvement in organizations and presents the author’s conceptual model of Quality 5.0 as a sustainable concept for quality improvement. The proposed model consists of 12 attributes of Quality 5.0, divided into four categories: (1) Balanced Techno-Human Centric Management System: agile and aware leadership, real-time data decision making, continuous improvement; (2) Human: empowerment, creativity, diversity; (3) Process: integration, efficiency, flexibility; (4) Technology: analytics, connectivity, and scalability. In the Quality 5.0 model, the organization supports the Triple Bottom Line of Sustainable Development through value co-creation, problem-solving, cooperation, and innovation.&#x0D; &#x0D; &#x0D;

Modeling of stakeholder influence on effectiveness of team decisions in the digital network space of crisis management centres of the EMERCOM of Russia

The article deals with issues related to modeling of stakeholder influence on effectiveness (sustainability) of teamwork in crisis management centres (hereinafter referred to as CMC) of the Ministry of the Russian Federation for Civil Defence, Emergencies and Elimination of Consequences of Natural Disasters (hereinafter referred to as EMERCOM of Russia) while analysing, forecasting development and resolving/reducing conflictness of social emergencies (hereinafter referred to as SE). The problem is considered from the perspective of using a nonlinear approach in modeling in the form of the Verhulst equation which allows to analyse complex social processes. The influence of different stakeholder groups is modeled at different values of the “a” parameter of its intensity– weak, medium, strong. The article presents the results of practical research on assessing the influence of stakeholders, primarily the external ones, on effectiveness (sustainability) of the CMC teamwork in the analysis, forecast of development, and resolution/reduction of conflictness of SE. The definition of SE is given as an attractor that has emerged due to unresolved social contradictions which have caused an imbalance in public relations. The work of the CMC teams is conducted in the digital network environment of the centres, and it introduces certain specifics into its activities. The research shows the general scheme of the stakeholder approach implementation in team management in the analysis, forecast of development and resolution/reduction of conflictness of SE. The author presents the results of the nonlinear modeling of effectiveness (sustainability) of the CMC teamwork, depending on the intensity of stakeholder influence on decisions made by the team. A system of indicators characterising the regression model of the “a” coefficient of stakeholder influence is proposed, the specific values of which can be measured during field research. Three modes (three types of attractors) of teamwork are investigated. The key objective of the study is to create prerequisites for the formation of a digital twin of the CMC teamwork of the EMERCOM of Russia in SE.

Perinatal outcomes of fetoscopic selective laser photocoagulation for spontaneous twin-anemia polycythemia sequence.

Antenatal management of monochorionic pregnancies complicated by twin anemia polycythemia sequence (TAPS) remains sub-optimally defined. Our objective was to evaluate the safety and efficacy of fetoscopic selective laser photocoagulation with respect to fetal and neonatal survival. A case series is reported with patients referred to the Texas Children's Fetal Center for evaluation and management of suspected spontaneous TAPS without concomitant twin-to-twin syndrome from 2014 to 2023. All evaluations were performed by our team and patients with stage II-IV TAPS were offered expectant management, intrauterine transfusion, or laser therapy. Cases of post-laser TAPS were excluded from this study. Pregnancy and neonatal outcomes were obtained from electronic medical records. During a 10-year time period, 18 patients presented to our center for the management of TAPS. Thirteen patients had stage II-IV TAPS (13/18, 72%) and elected to proceed with laser photocoagulation. All procedures were completed, and "solomonization" was performed for 12/13. Normalization of middle cerebral artery Dopplers in both fetuses was noted after all cases. There was one intrauterine fetal death of the 26 viable fetuses after laser treatment, which was complicated by selective growth restriction. Most patients (12/13) were delivered by Cesarean section at a mean gestational age of 29±3weeks. Subsequently, there was one ex-donor neonatal death in an infant who had prenatal hydrops. Overall, 30-day postnatal survival was 24/26 fetuses (92.3%). In the setting of spontaneous TAPS, laser therapy is feasible and appears to be an effective approach with overall favorable perinatal outcomes.

Design and eco-technoeconomic analysis of a natural gas cogeneration energy management center (EMC) with short-term thermal storage

This work proposes a non-islanded cogeneration energy management center (EMC) that can be used to displace grid-level natural gas turbine systems and natural gas combustion systems for heat. The design of the proposed EMC included a weighted multi-objective optimization aimed at minimizing: i) natural gas consumption; ii) capital costs; iii) utility costs; and iv) unmet thermal demand. The decision variables consisted of the existence and capacity of the equipment comprising the EMC, including: i) a natural gas boiler; ii) an internal combustion engine that generates heat and electricity; and iii) a hot water thermal storage system. Four resulting candidates EMC designs were then compared with the status-quo (SQ) in an eco-technoeconomic analysis; The SQ draws electricity from the grid and heating for dwellings come from natural gas boilers. Emissions at grid level change which alternative is favored. The findings showed that, for a system that serves 4–5 dense urban city blocks over a 20-year lifetime, the SQ system had cumulative levelized costs of 9.6 million USD for the final consumer, while the levelized costs of the EMC designs ranged from 12.9 to 15.1 million USD. In terms of emissions, the SQ emitted 959 tonnes of CO2eq per year, while the EMC system produced around 500 tonnes of CO2eq per year depending on the year, yielding a CCA varying between 364 and 653 USD/tonneCO2eq
