| 1 | A Method for Improving Power Distribution Characteristics of Space Time Block Codes显示文摘Improving power distribution characteristics of space time block codes(STBCs),namely peak to average power ratio(PAPR),average to minimum power ratio(Ave/min),and probability of transmitting'zero'by antenna,makes easier their practical implementation.To this end,this study proposes to multiply full diversity STB C with a non-singular matrix in multiple input multiple output(MIMO)or multiple input single output(MISO)systems with linear or maximum likelihood(ML)receivers.It is proved that the obtained code achieves full diversity and the order of detection complexity does not change.The proposed method is applied to different types of STBCs.The bit error rate(BER)and power distribution characteristics of the new codes demonstrate the superiority of the introduced method.Further,lower and upper bounds on the BER of the obtained STBCs are derived for all receivers.The proposed method provides trade-off among PAPR,spectral efficiency,energy efficiency,and BER. | Vahid Abbasi Mahrokh GShayesteh | 2020 | China Communications2020，17，6： | 3 |

| 10 | 伊朗护士关于家庭护理伦理问题的质性研究显示文摘目的鉴于院外护理服务的重要性,家庭护理的出现,以及护理实践中伦理框架的需求,本研究旨在探讨护士对家庭护理中伦理问题的看法和体验。方法采用面对面个人访谈收集资料。2020年,通过目的性抽样方法选取在伊朗4个城市的家庭护理中心中工作的20名护士进行访谈,了解他们在家庭护理过程中关于伦理问题的看法和体验。基于内容分析法,应用Granehei和Lundman方法对资料进行分析。结果本研究共提取编码416个。基于相似性对编码进行合并,提取出7个主题和16个子主题。主题包括对职业身份的感知、尊重患者的自主权、尊重隐私、建立人际交往、维护相互安全、遵守公平性原则和文化-宗教能力。子主题包括责任、专业发展及专业间互动、在家庭护理中保持专业性、提供整体性和艺术性的护理、尊重患者隐私、尊重护士隐私、信息保密、尊重服务对象的选择、诚实告知、富有同情心的互动、平衡权力地位、维护患者安全、维护护士安全、公平性的建立、尊重家庭宗教信仰,以及注重文化敏感性。结论研究参与者表示由于在家庭护理中涉及患者隐私,与在医院环境中的护理实践相比,家庭护理中对于护士职业身份的认知、隐私、家庭互动的管理、相互安全和文化-宗教能力等伦理问题显得尤为重要。 | Masoume Arab Mohsen Shahriari Amir Keshavarzian Abbas Abbaszadeh Mahrokh Keshvari | 2022 | International Journal of Nursing Sciences2022，9，3： | 0 |
