Objective: Hemodialysis patients suffer many problems including feelings of loneliness, fatigue, and low lifestyle quality. This study aimed to investigate the effectiveness of online existential consciousness therapy on these patients’ loneliness, fatigue, and lifestyle. Methods: The research method was quasi-experimental with a pretest-posttest and follow-up design with a control group. The research population was all hemodialysis patients who were referred to the dialysis center of Nikan Hospital in Tehran. Using the convenience sampling method, 30 participants were selected as study samples. Research instruments for collecting data were the Rasel’s Loneliness Questionnaire (1978), the Fieck’s Fatigue Impact Questionnaire (1944), and the Corona Virus Lifestyle Scale (Ali Akbari Dehkordi, et al., 2020). For the experimental group, ten 90-minutes sessions were performed through Sky-room. Results: MANCOVA and ANCOVA showed that existential consciousness training reduced the feeling of loneliness in the sub-components of not having a close friend, lack of loneliness, and isolation, but was not effective in the sub-component of sociability. This intervention also reduced the fatigue in the cognitive and social components but did not affect the physical component. It was also effective on the happy lifestyle but did not affect on the healthy lifestyle. Conclusions: Existential consciousness therapy was effective in reducing the loneliness feeling, fatigue impact, and lifestyle changes of hemodialysis patients during home quarantine. Therefore, this method can be used as a new therapeutic approach to reduce the loneliness and fatigue impact caused by hemodialysis and change patients' lifestyles during quarantine in medical centers and psychological services.

The innovation ecosystem plays a valuable role in the development of innovation and entrepreneurship. The emergence of an innovation-based economy requires the development of an innovation ecosystem in the context of the region. In most countries, especially less developed countries, the ecosystem is not properly formed and the first step to its formation is the theoretical and experimental knowledge of this area. Therefore, this study aims to investigate the dimensions and components of the innovation ecosystem. We applied bibliometric method, citation analysis, applied evaluation techniques and content analysis of documents in this research. The purpose of this research is to review studies in this field and to present a conceptual and integrated model using content analysis of documents by organizing previous research. The statistical population of this research includes all the documents presented in the Web of Science database with 438 documents related to the innovation ecosystem until 2020 and has been evaluated and illustrated using VOS viewer software. Based on the content analysis of the documents, research on the "innovation ecosystem" is divided into five sections. The first part of the research is related to the structural factors. The second part is related to the type of the relationships and interactions, and the third part is related to the results. The fourth part is about the actors and the fifth part is about how they have performed. Finally, the conceptual framework of the research is presented based on the content analysis of the documents
