Abstract： Background Previous studies have found that 25%-85% of stroke patients develop post-stroke fatigue （PSF），and continuous feeling of fatigue seriously affects patients' daily life and rehabilitation process. Therefore，it is urgent to understand the psychological experience and needs of such patients. However，the results of previous single qualitative studies may not be representative. Objective To systematically review and integrate qualitative studies on the fatigue experience of patients with PSF，so as to provide a reference for the construction of management strategies for PSF patients. Methods PsycINFO，PubMed，Web of Science，CINAHL，Cochrane Library，Scopes，Joanna Briggs Institute（JBI）Evidence#2;Based Health Care database，CNKI，Wanfang，VIP，CBM were searched by computer to screen qualitative studies on fatigue experience of patients with PSF from inception to July 5，2023. JBI Critical Appraisal Tool for qualitative studies in Australia was used to evaluate the quality of included literature，and Meta-synthesis was performed to integrate results. Results A total of 10 papers were included，and 22 primary outcomes were distilled，grouped into 8 categories，and synthesized into 4 integrated outcomes，including significant lack of cognition of PSF；intricate negative physical and psychological experience；differentself-regulation of PSF and multiple needs for PSF rehabilitation. Conclusion PSF patients have insufficient cognition of fatigue with significant negative physical and psychological experience. Therefore，PSF patients should be identified and screened at an early stage with strengthened fatigue education and personalized fatigue management strategies. Emphasis should also be placed on the role of community and family in the management of fatigue，so that they can work together with healthcare professionals to provide a favorable rehabilitation environment for PSF patients.

Abstract： [Purpose/significance] This article aims to understand the information security knowledge, information security awareness and behavior of undergraduates, to find the existing relationships and problems, and to propose countermeasures.[Method/process] Through questionnaire survey, the smart phone users in Tianjin Polytechnic University students are investigated from five areas of the basic personal information of users, the use of smart phone information security awareness, smart phone user information security behavior, smart phone user information security knowledge, the source of user information security knowledge and the degree of knowledge needs.[Result/conclusion] The investigation and analysis show that college students smartphone users have better knowledge of common-sense information security than professional ones,the awareness of information security is relatively weak, and the awareness of boys is higher than that of girls. There is a great hidden danger in information security and information protection should be strengthened. Information security knowledge is the premise of information security awareness, and information security awareness is expressed through behavior, but awareness of information security does not necessarily translate into practical behavior. There is a significant difference between gender and information security awareness as well as information security behavior, but there is no significant difference with information security knowledge. Finally, according to the status quo of the investigation, this paper puts forward three suggestions:cultivating students' ability of identifying information security threat, avoiding information security risk, improving students' basic ability of information security protection, and strengthening students' ethics of information security and education of laws and regulations.

Abstract： Obstructive sleep apnea（OSA） is a common sleep-related respiratory disorder that can easily induce or aggravate a variety of diseases，often causing different levels of decline in the patient's quality of life. Patient-reported outcome（PRO） assessment tools provide effective means for evaluating both quality of life and clinical efficacy. There are numerous OSA-PRO assessment tools available，primarily developed in foreign countries，mainly covering domains such as symptoms，daily activities，social activities，and psychological emotions，with items ranging in number from one to 84，and Likert scale as the main type of response scale. The development and evaluation of these tools employ the Classical Test Theory（CTT）. We provide the following recommendations for future research: evaluating the psychometric properties and methodological quality of OSA-PRO assessment tools；combining CTT with Modern Test Theory to develop，revise，and evaluate OSA-PRO assessment tools；strengthening the research on the minimal clinically important difference of OSA-PRO assessment tools；developing OSA-PRO assessment tools highlighting the clinical efficacy of traditional Chinese medicine.

Abstract：
The micro-piles have been widely used in transmission line tower foundation on soft soil foundation,but it is relatively less used on loess foundation.In order to study the uplift and press bearing capacity of micro-pile foundation on loess foundation,the effects of pile length,pile diameter and loess collapsibility on the bearing capacity of micropiles are analyzed based on the field static load test.To overcome the limitation of the field test,the three-dimensional finite element models of pile-soil interaction are established to compare the results of numerical analysis and experimental results.The finite element model is verified,and then used to analyze the effects of different pile length and pile diameter pile elastic modulus on the uplift and the compressive load performance.The results could be drawn from this study show that the impact of loess collapsibility on the compressive bearing capacity of micro-pile is greater than that of uplift bearing capacity,and the failure curve of the micro-pile foundation after immersion in water presents a more obvious steep drop.The vertical bearing capacity of micro-pile on loess foundation is mainly determined by pile lateral friction resistance.The influence of pile length on ultimate bearing capacity is more significant than that of pile diameter.The above research has good reference value for the application of micro-pile foundation on loess ground.

Abstract： As a common ingroup, the Chinese nation community has unique characteristics. First, its properties are complex. Second, as an entity, it has various components. However, previous studies focused more on macro analysis, theoretical generalizations, and policy interpretations and less on microscopic arguments and empirical studies. Therefore, an empirical study on the identity of the Chinese nation community must be carried out. This study employs senior high school students who grew up in Tibetan areas and are current hinterland senior high school students to participate in three experiments. The most special characteristic of Tibetan students is their experiences on cross-ethnic communication and cross-cultural life. In Experiment 1, 50 Tibetan students in hinterland senior high school were employed as subjects. The relationship of the container and the community for the Chinese nation was investigated through the Spatial Stroop Paradigm. In Experiment 2, 50 Tibetan students were also employed as subjects. The Emotional Stroop Paradigm was used to explore the attitude of Tibetan students toward domestic and foreign ethnic groups. In Experiment 3, 320 Tibetan students were employed. Situational tasks of Money Helps and Time Helps were used to test the willingness to help someone from the domestic ethnic group or foreign ethnic group. Experiment 1 exhibited that the reaction time was significantly shorter when a domestic name appeared in the circle or a foreign name appeared outside the circle, which revealed that Tibetan students constructed the community for the Chinese nation as a container, placed the domestic ethnic groups in the container, and placed the foreign ethnic groups outside the container. Experiment 2 unveiled that the judgment reaction time of the positive target word was significantly shorter when the prime word was a domestic ethnic group name, and the judgment reaction time of the negative target word was significantly shorter when the prime word was a foreign ethnic group name, indicating that Tibetan students preferred the domestic ethnic groups and prejudiced the foreign ethnic groups. Experiment 3 showed that Tibetan students donated more money and time to someone from the domestic ethnic group who needed help, signifying that Tibetan students in hinterland senior high school had a stronger willingness to help domestic ethnic groups. This study suggests that Tibetan students in hinterland senior high school with rich experience on cross-ethnic communication and cross-cultural life constructed the Community for the Chinese nation as a container, and placed domestic ethnic groups in the container. Conclusively, Tibetan students had varying attitudes and different levels of help willingness toward domestic and foreign ethnic groups.

Abstract： In order to clarify the influence of horizontal bearing capacity of micro-piles on superstructuresafety performance , the effects of pile length , pile diameter , pile elastic modulus and pile spacing on hori-zontal bearing capacity of micro-pile on loess foundation are studied based on in-situ static load test.'Thevariation of pile displacement and bending moment along the foundation depth under different horizontalloads are analyzed.And the influence of pile spacing on the horizontal bearing capacity of pile groups isanalyzed with the aid of the verified finite element model.The results show that the position of the greaterbending moment of micro-pile foundation on loess soil is about 4d-5d from pile top. The pile diameter hasa greater impact on the horizontal bearing capacity of the micro-pile, but the influence is relatively smallwhen the pile length exceeds the optimal pile length (33d-35d). When the pile spacing reaches 8d , the in-fluence of the pile group effect on the horizontal bearing capacity of the pile group can be ignored. The a-bove research results provide some reference for the application of micro-pile on loess foundation.
