Open Journal of Nursing 2022年第11期12卷 725-737页

作者： Suniti Halder Poly Rani Kundu Auparna Biswas Senior Staff Nurse Dhaka Medical College Hospital Dhaka Bangladesh Senior Staff Nurse Sadar Hospital Narail Narail Bangladesh Senior Staff Nurse National Institute of Cancer Research and Hospital Dhaka Bangladesh

Objectives: To assess the nurses’ experiences in service provision a COVID-19 dedicated tertiary public hospital. Materials and Methods: This descriptive cross-sectional study was conducted in one tertiary level public hospital namely Dhaka Medical College Hospital (DMCH), Dhaka, Bangladesh from January to December 2021. Data were collected through face-to-face interview using a structured questionnaire containing demographic details and experiences faced by the nurses in service provision during COVID-19. Data was analysed by using SPSS (Statistical Package for Social Science) software version 23. Results: The findings revealed that the mean age of the respondents was 32.35 ± 7.248 years, the minimum age was 23 years and maximum age was 58 years. About half of the respondents 52.1% were in 21 - 30 years. The majorities 89% were female. More than half of the respondents 72.6% were Muslim and 63.83% of respondents have completed Diploma in nursing. About 32.2% respondents were living with senior citizen, 33% respondents were infected by COVID-19, 24.23% respondent mentioned nurse-Patient ratio in general ward was 1:7 and 71.08% mentioned nurse-patient ratio in I.C.U/C.C.U. was 1:3 (December 2021). PPE were available among 88.0% respondents and N95 mask were available among 84.0% respondent. About 34.8% respondents got COVID-19 guideline training and 32.4% got donning and doffing training. More than half of the respondents 76% stated that equipment is adequate, 56.38% respondents mention that insufficient of nurses and 53.7% were mentioned insufficient of subordinate staff. About 22.6% respondents faced social stigma and majorities 96.5% respondents mentioned they got proper family support. There was a significant association found between Professional educational qualification and satisfaction of current designation (p value = 0.001 Conclusion: The most important findings of this study was lack of training, insufficient of manpower especially nurses and subordinate s

A Model of Grid service Capacity

引用

Journal of Computer Science & Technology 2007年第4期22卷 505-514页

作者： Youcef Derbal School of Information Technology Management Ryerson University350 Victoria StreetTorontoONM5B 2K3Canada

Computational grids （CGs） are large scale networks of geographically distributed aggregates of resource clusters that may be contributed by distinct organizations for the provision of computing services such as model simulation, compute cycle and data mining. Traditionally, the decision-making strategies underlying the grid management mechanisms rely on the physical view of the grid resource model. This entails the need for complex multi-dimensional search strategies and a considerable level of resource state information exchange between the grid management domains. In this paper we argue that with the adoption of service oriented grid architectures, a logical service-oriented view of the resource model provides a more appropriate level of abstraction to express the grid capacity to handle incoming service requests. In this respect, we propose a quantification model of the aggregated service capacity of the hosting environment that is updated based on the monitored state of the various environmental resources required by the hosted services. A comparative experimental validation of the model shows its performance towards enabling an adequate exploitation of provisioned services.
