It should be adjusted to achieve the normal oxygen saturation of 94%–98% in most cases. This study aims to evaluate knowledge, attitude and practice(KAP) of nurses, paramedics, emergency medical technicians(EMTs) and Emergency Medical Services(EMS) physicians working at emergency departments(ED) in Riyadh, Saudi Arabia. METHODS: In this cross-sectional study, a structured questionnaire was used to assess KAP related to OT of nurses, paramedics, EMTs and EMS physicians currently working at an ED of a tertiary care hospital. Knowledge and attitude were assessed using a Likert scale from 1–5, whereas practice was assessed as a yes/no categorical variable.RESULTS: A total of 444 emergency health-care workers(EHCWs) participated, of which 225(50.7%) were male, with the majority(77%) in the age group of 20–35 years. Over half of the sample were nurses(266; 59.9%). The mean score for knowledge about OT was 5.51±1.45, attitude was 26.31±3.17 and for practices 4.55±1.76. The main factors which were associated with poor KAP were workload and lack of local guidelines. The distribution of overall practice score was signifi cantly better among paramedics – nurses group and EMT – nurses group.CONCLUSION: This study demonstrates that there is a gap in EHCWs' KAP, particularly regarding when to provide OT to a patient. This gap can affect patients' safety. Extensive educational and training programs about OT are needed to raise awareness among health-care providers.展开更多

To sort out reasonable agricultural practices favorable to abating soil acidification, the task of this study was directed to a long-term field trial in Chongqing, dudng which chemical fertilizer, organic fertilizer were applied to different crop rotations and the soil pH value was measured. The results indicated that all treatments decreased pH value in the 0 to 20 cm soil layer after ten years. Problems were more serious when chlorine-containing fertilizer, excessive chemical fertilizer and mixed fertilizer were applied. It is demonstrated that balance rates of N, P and K fertilizers, application of muck in field are advantageous to abating soil acidification. Oil plants affect soil acidification more than cereal in different crop rotation.展开更多

Recently, the world has witnessed the improvement of the bilateral relations between the two big nations. The White Horse Temple, as a site constructed by discourses has transformed from‘the first government-funded temple in China'to one of the symbols of China-India friendship in the cultural exchange between the two nations. Critical discourse analysis(CDA) is an interdisciplinary approach to the study of discourse that views language as a form of social practice and focuses on the ways social and political domination are reproduced in text and talk. This paper, starts from the perspective of critical discourse analysis, is exploratory in that it aims to see how the discursive practice of the White Horse Temple constitutes the discourse of China-India relationship and is constituted by the power relationship between the two nations.展开更多
