Review on Development of Pressure Injury Prevention Fabric

Pressure injury is a common postoperative complication of wheelchair users. It has a high incidence rate and can induce sepsis and even death. The fabrics that touch patients’ skin directly have a profound impact on their skin surfaces. This review summarizes the research in the last five years on the relationship between pressure injuries and fabrics. Following the preferred reporting items for systematic reviews and meta-analyses(PRISMA) statement, a systematic literature search is conducted in nine databases, including SCI(Web of Science), IEEE, ASTM, Taylor & Francis, ProQuest, Wiley, SpringerLink, PubMed and SAGE. The research objects, experimental equipment and survey results are investigated in this review, in which twenty-four different textiles and seven different test methodologies are involved. The test methodologies include five kinds of performance tests and two kinds of observational studies. Two studies showed that the particular fabric was helpful to reduce the pressure on the skin surface, and twelve studies revealed that the multi-layer fabric with good air permeability, heat dissipation and moisture dissipation was helpful to prevent pressure injury. This review confirms the correlation between the fabric properties and the occurrence of postoperative pressure injury in wheelchair users. Further experiments are needed to reasonably integrate the fabric characteristics of pressure injury prevention into the mass-produced pressure injury prevention clothes for wheelchair users.

Research on the Developmental Venation of Calligraphy Seal Cutting Art Form from the Perspectives of Chinese Traditional Culture and Art Form

In this paper, we conduct research on the developmental venation of the calligraphy seal cutting art form from the perspectives of Chinese traditional culture and art form. Seal cutting art of composition is a word or group of words arranged on the surface of the printing art, complex and changeable, is one of the most important part of the seal cutting art. Complete the creation of the group, must all have change, should show more creators on the composition of work force, therefore when designing should be repeated according to the text specifi c stroke, handwriting, the form and the relationship between word and word to design the structure of the right. Cultivating must practice the socialist core values and should be based on the basis of the Chinese excellent traditional culture, in carrying forward and greater China outstanding traditional culture in the process of makes it obtain nourishes the spirit and the value of the national identity. Our research provides the countermeasure for further modifi cation and optimization that is meaningful and necessary.

Surviving the shift: College student satisfaction with emergency online learning during COVID-19 pandemic

BACKGROUND The coronavirus disease 2019(COVID-19)epidemic disrupted education systems by forcing systems to shift to emergency online leaning.Online learning satisfaction affects academic achievement.Many factors affect online learning satisfaction.However there is little study focused on personal characteristics,mental status,and coping style when college students participated in emergency online courses.regression analyses were performed to identify factors that affected online learning satisfaction.RESULTS Descriptive findings indicated that 62.9%(994/1580)of students were satisfied with online learning.Factors that had significant positive effects on online learning satisfaction were online learning at scheduled times,strong exercise intensity,good health,regular schedule,focusing on the epidemic less than one hour a day,and maintaining emotional stability.Positive coping styles were protective factors of online learning satisfaction.Risk factors for poor satisfaction were depression,neurasthenia,and negative coping style.CONCLUSION College students with different personal characteristics,mental status,and coping style exhibited different degrees of online learning satisfaction.Our findings provide reference for educators,psychologists,and school adminis-trators to conduct health education intervention of college students during emergency online learning.

Research on the Novel Facial Expression Modelling Method

In this paper, we conduct research on novel and new facial expression modelling method. Although human facial expression recognition ability is stronger, but the computer to implement is a lot of diffi culties and the displays in: establish facial expression model and sentiment classifi cation, and put them with the changes in the facial features and expressions. Face is a fl exible body instead of rigid body, it is diffi cult to relate facial movement and facial expression change, according to the characteristics of the face image sequence established dynamic expression model that is a complete description of the dynamic expression of the process. Under this condition, in this paper, we propose the novel perspectives of the issues that are meaningful and innovative.
