Corroborative Activities and Recognition Between Community Comprehensive Care Unit’s Nurses and Care Managers in Supporting Discharge of Elderly from Hospital - A Secondary Publication

Objective: The purpose of this study was to clarify the collaborative activities and mutual recognition between community comprehensive care unit nurses (Ns) and care managers (CM) in supporting the discharge of the elderly from the hospital. Methods: A total of 300 nurses working in community comprehensive care wards and 360 care managers working in B City in A Prefecture were surveyed using an anonymous self-administered questionnaire. Results: The highest percentage of responses regarding necessary collaborative activities with multiple professions in supporting hospital discharge were the same for Ns and CMs. The items regarding practice with the highest percentages were “relationship as a team” for Ns, and “user-centered awareness” for CM. While these professionals were willing to share information about their patients’ lives after discharge, the percentage of those explaining their expertise was low. It is thought that collaborative activities focusing on these aspects would lead to more appropriate discharge support.

UV,five wavelengths fusion and electrochemical fingerprints combined with antioxidant activity for quality control of antiviral mixture

Aiming to ensure the consistency of quality control of Traditional Chinese Medicines(TCMs),a combination method of high-performance liquid chromatography(HPLC),ultraviolet(UV),electrochemical(EC)was developed in this study to comprehensively evaluate the quality of Antiviral Mixture(AM),and Comprehensive Linear Quantification Fingerprint Method(CLQFM)was used to process the data.Quantitative analysis of three active substances in TCM was conducted.A fivewavelength fusion fingerprint(FWFF)was developed,using second-order derivatives of UV spectral data to differentiate sample levels effectively.The combination of HPLC and UV spectrophotometry,along with electrochemical fingerprinting(ECFP),successfully evaluated total active substances.Ultimately,a multidimensional profiling analytical system for TCM was developed.

Comprehensive Multi-Level Exploration of Buried Active Faults:an Example of the Yinchuan Buried Active Fault

The paper introduces the steps and methods of multi-approach, multi-level exploration of buried faults in thick Quaternary sediment regions by taking the test exploration of the Yinchuan active fault as example. Based on the comprehensive analyses of previous data, we choose the Xinqushao Village of Xingqing District of Yinchuan City as the test site for the comprehensive exploration. Firstly, we adopted shallow seismic investigation with group intervals of 10m, 5m and lm to gradually trace layer by layer the master fault of the Yinchuan buried fault from a deep depth to a shallow depth where drilling could be used. Then, with composite geological profile drilling, we determined the precise location and dip angle of the fault. The drilling show the buried depth of the upper offset point is 8.3m. Finally, large-scale trenching revealed that the actual buried depth of the upper offset point of the fault is 1.5m from the ground surface and there are paleoearthquake events of 5 stages. Combined with the preliminary result of corresponding sample age, we conclude the Yinchuan buried fault is a mid to late Holocene active fault.

Taking Comprehensive Practice Activities as the Carrier to Improve College English Teaching Efficiency

The so-called comprehensive practice activities refer to that under teachers＇ guidance, students conduct independent comprehensive learning activities, and in activities, students can train practice ability, organically combining theory knowledge and practice knowledge together, in order to have a learning and practice effect. In current college English teaching, it exists module, single and dogmatic and a series of disadvantage trends, taking comprehensive practice activities as the carrier to improve college English teaching efficiency, which has a multiplier effect. This paper first analyzes the importance of comprehensive practical activities in college English teaching activities, and then it proposes a set of practicable activity strategies, hoping to play a valuable role.

The Effects of a Community and School Sport-Based Program on Urban Indigenous Adolescents’ Life Skills and Physical Activity Levels: The <i>SCP</i>Case Study

The primary aim of this study was to investigate the effect of a community and school sport program (SCP) on Indigenous adolescents’ life skills and physical activity levels within program sessions. A secondary aim was to determine the acceptability of the SCP. Participants in the SCP (n = 34;89%) participated in a 10-week case study (age = 13.7 ± 1.16;58% girls). Systematic observations of SCP sessions were conducted to determine physical activity levels and a life skills questionnaire was implemented. Acceptability measures included retention, implementation, attendance rates, and interviews with participants [n = 18] and key stakeholders [n = 6]. Systematic observations indicated that Indigenous students were engaged in MVPA for 58% of lesson time. Participants’ life skills remained unchanged (p = 0.93). Interview data showed that Indigenous students and key stakeholders believed the SCP was acceptable. This study highlights the need for partnerships between Indigenous community organisations and schools to design sport-based programs to promote Indigenous adolescents’ MVPA.

置信职业行为在老年医学住院医师老年综合评估培训中的应用

人口老龄化是我国社会当前和今后相当长一段时间的显著特征,如何应对老年人口增长给医疗领域带来的压力、如何实现健康老龄化,是当前面临的重大任务。老年综合评估以老年患者为中心,包含躯体疾病、心理健康、生活环境、社会支持等全方位内容,是实现个体化诊疗、促进健康老龄化的有效方法。鉴于老年综合评估过程复杂,传统的培训方法难以让学习者迅速掌握相关内容,也无法用量化指标体现学习者的掌握程度,不利于指导教师对他们进行有效评价。浙江大学医学院附属第一医院老年医学科将置信职业行为应用于老年医学住院医师老年综合评估培训中,将老年综合评估过程中所有关键环节提取出来,并设定分级标准,为学习者提供了明确的学习框架,描述了不同阶段应当达到的置信等级,这有助于弥合教学理论和临床实践之间的差距,在教学实践中亦初步展现了良好的效果。在今后的工作过程中,应该完善置信职业行为的评价方法及其在老年综合评估培训中的应用,同时探索其在老年医学住院医师规范化培训等其他教学方面的价值,促进学习者和教学者的共同进步,为健康老龄化发挥积极的作用。
