This paper takes the Belt and Road Initiative for example,emphasizing the interpretation of the inheritance and development of Chinese culture so as to study the importance of Culture Self-Consciousness in Chinese Philosophy,in the context of English globalization. That is to say,this paper stresses the spirits and the stand of nation 's demonstration on pursuing peace,cooperation and sustainable development in the civilization continuity from traditional China to the contemporary China,with practical philosophic view.展开更多

The lack of such is the main barrier for waste separation willingness and practices in Cambodia. Self-transcendence values and volunteerism are empirically found as the fundamental factors for any interventions designed to promote pro-environmental intentions and practices respectively. The fellows engaging in volunteerisms appear to do waste separation, ignoring how inconvenient the waste management system or facilities are. Similarly, the fellows concerning the environmental and social issues appear to spare their valuable time to do waste-separation which they find not difficult. This is not the case in this COVID-19 epidemic though. The study results imply that in a society where an inconvenient waste management system is in place the fellows without past volunteering, no matter how knowledgeable they are, will less likely engage in the waste-sorting practice.展开更多
目的:探讨自我超越理论护理模式结合柴胡疏肝散加减在乳腺癌术后治疗中国的应用及对患者自护能力的影响。方法:选取乳腺癌术后患者72例,随机分为对照组和观察组,每组各36例。对照组采用乳腺癌术后常规护理,观察组在此基础上采用自我超...目的:探讨自我超越理论护理模式结合柴胡疏肝散加减在乳腺癌术后治疗中国的应用及对患者自护能力的影响。方法:选取乳腺癌术后患者72例,随机分为对照组和观察组,每组各36例。对照组采用乳腺癌术后常规护理,观察组在此基础上采用自我超越理论护理模式结合柴胡疏肝散加减治疗,术后共干预2周。对比干预前后两组Herth希望量表(herth hope index,HHI)、自我超越量表(Chinese version of the self-transcendence scale,CSTS)、汉密顿焦虑量表(Hamilton anxiety scale,HAMA)、汉密顿抑郁量表(Hamilton depression scale,HAMD)、自我护理能力量表评分及血清肿瘤标志物水平。结果:干预后,两组HHI、CSTS及自我护理能力评分均高于治疗前(P<0.05),HAMA、HAMD评分及血清肿瘤标志物水平均低于治疗前(P<0.05)。干预后观察组HHI、CSTS及自我护理能力评分均高于对照组(P<0.05),HAMA、HAMD评分及血清肿瘤标志物水平均低于对照组(P<0.05)。结论:自我超越理论护理模式结合柴胡疏肝散加减治疗,能有效提高乳腺癌患者术后的希望水平、自我超越水平及自我护理能力,缓解患者焦虑和抑郁情绪,降低血清肿瘤标志物水平,提高生活质量。展开更多
