ABSTRACT
Objective:To develop an intelligent vision examination and management system based on mobile terminal, and evaluate its practical application.Methods:A diagnostic test study was adopted.Fifty children and adolescents (100 eyes) aged from 3 to 14 years, with an average age of (8.16±4.58) years, were enrolled in Zhongshan Ophthalmic Center from March to May, 2020.An intelligent vision examination and management system for Android and IOS devices, which applied technologies of real-time range measurement, speech recognition, and gesture recognition to achieve the real-time interaction in the vision examination, was developed using JAVA language and xcode11.The uncorrected visual acuity of subjects was tested with the intelligent vision system and the standard eye chart in hospital.The difference in the number of cooperative eyes between the two methods was analyzed by χ2 test.The LogMAR acuity of the two methods were compared by Wilcoxon rank sum test and the consistency between the two methods was analyzed by Kappa test.The study adhered to the Declaration of Helsinki, and the study protocol was approved by an Ethics Committee of Zhongshan Ophthalmic Center (No.2020KYPJ095). Written informed consent was obtained from guardians of each subject prior to any examination. Results:The intelligent vision examination and management system was successfully developed for Android and IOS devices, which was loaded with precise vision examination at 3 meters, intelligent interaction, result output and automatic filing functionalities.The inspection range of visual acuity was from 0.1 to 1.5.The size and resolution of eye chart met the national standard.There was no significant difference in the number of cooperative eyes during examination between traditional eye chart (99/100) and intelligent vision examination system (98/100) ( χ2=0.338, P=0.561). There was no significant difference in examination results between traditional eye chart 0.3 (0.2, 0.5) LogMAR and intelligent vision examination system 0.3 (0.2, 0.5) LogMAR ( Z=-1.602, P=0.109), and there was a high consistency between the two methods (Kappa coefficient=0.885). Conclusions:The intelligent vision examination and management system based on the mobile terminal is of high accuracy and practicability, which can effectively meet the public demand for at-home vision testing and long-term tracking.The system can be promoted and applied as a new mode for personalized eye health management.
ABSTRACT
Objective To sort out the functional composition of the official App of a tertiary general hospital, and its usage. Methods Taking the tertiary general hospitals identified from the national hospital quality monitoring system as the research objects, statistically analyzing their functional composition, and comparing the App and WeChat public platform of two hospitals as examples.In addition, collecting relevant data from the official website of the hospital, and analyzing the influencing factors of its download and usage with multiple linear regression methods. Results There were 469 tertiary general hospitals nationwide, of which 137 had official Apps, with an accessibility rate of 29.21%.The accessibility rated in the eastern, central and western regions were 27.85% , 13.48% and 17.43% respectively.Hospital App prioritized in turn appointment registration (94.9% ), test report ( 76.8% ), and hospital navigation ( 71.7% ). The development of the hospital App in the eastern region taked the lead compared to the middle and western ones.The App′s score and the total outpatient visits of hospital had a positive impact on the download and use of the hospital App.The App′s scoring had a noteworthy impact. Conclusions Hospitals should enable to innovate their services, and highlight their characteristics.App should optimize its interface, improve its functions, enhance the interconnection of App functions, strengthen data security management, strengthen its publicity and expand its influence.
ABSTRACT
Objective To understand the health literacy status,influencing factors and demand carrying out the health education based on the mobile terminal among college students to provide a new idea for formulating and implementing the health literacy promotion plan for university students.Methods The multi-stage stratified cluster random sampling method was adopted to extract 1 949 students from partial universities in Nanjing City and conduct the investigation by adopting the Rapid Estimate System of Health Literacy and Health Education Demand Based on the Mobile Terminal Questionnaire of College Students.The influence factors were analyzed by using the univariate analysis and ordinal multi-classification Logistic regression analy sis.Results The university students with high,marginal and low health literacy level accounted for 31.3％,48.9％ and 19.8％ respectively.The proportions of the students with high health literacy in the four dimensions,including health knowledge,health behaviors,health skill and health status,were 57.9％,18.3％,61.0％ and 44.5％ respectively.The ordinal multi-classification Logistic regression analysis showed that the major influence factors affecting the health literacy of university students were gender,education background of mothers,majors,grades,electively taking the health education course.81.2 ％ of university students wanted to or urgently wanted to understand the health literacy knowledge.The main route getting the health literacy knowledge by the university students was network(83.8％).91.8％ of students were willing to learn the health literacy knowledge through mobile terminal.87.1％ of students believed that the WeChat was suitable to learn the health knowledge,81.3％ of students hoped to use the WeChat platform for learning the health knowledge,73.8％ of students hoped the Wechat to push the health knowledge with the modes of words combined with images and video.It was recommended that the health knowledge pushing for 1-3 times per week was suitable.Conclusion The health literacy of university students is at the marginal level.The health behaviors literacy is most lacking and the demand for the health education based on the mobile terminal is stronger.The health literacy intervention of university students should sufficiently apply the new media platform superiority and the emphasis should be placed on the populations of males,low education background mothers,non-medicine major,low grade and without electively taking the health education course.
ABSTRACT
In this paper, a data acquisition system based on mobile terminal combining GPS, offset correction, automatic speech recognition and database networking technology was designed implemented with the function of locating the latitude and elevation information fast, taking conveniently various types of Chinese herbal plant photos, photos, samples habitat photos and so on. The mobile system realizes automatic association with Chinese medicine source information, through the voice recognition function it records the information of plant characteristics and environmental characteristics, and record relevant plant specimen information. The data processing platform based on Chinese medicine resources survey data reporting client can effectively assists in indoor data processing, derives the mobile terminal data to computer terminal. The established data acquisition system provides strong technical support for the fourth national survey of the Chinese materia medica resources (CMMR).
ABSTRACT
Mobile learning behaviors are the greatly concerned hotspot in educational field.However, the specific mobile learning behaviors of university undergraduates are not subdivided in the current researches.The mobile learning behavior data of university undergraduates in different learning circumstances were recorded by literature survey, interview and questionnaire investigation, the characteristics of mobile learning behaviors were subdivided and analyzed in order to help them work out their strategy for mobile learning in different learning circumstances, which showed that the frequency of intelligent mobile learning was higher than that of traditional mobile learning in specific academic activities (academic exchange, self learning, academic sharing, transmission and search), and that the new generation of digital young people showed their preference to mobile learning due to its advantage of convenience while the disadvantage of its function and operation limited its persistent use.It is thus the hope of university undergraduates, especially medical undergraduates, to develop more devices and tools that are convenient for their mobile learning by making use of the advantages of intelligent mobile terminal and traditional terminals.
