摘要： Introduction: The Child health booklet has been shown to be an essential tool for monitoring the implementation of interventions with a high impact on reducing infant and child mortality. Objective: To describe the opinion of child health providers about child health records. Methodology: Cross-sectional survey of health professionals on content, ease of use and recommendations for a health record of the ideal child. Results: About 3/4 (75%) of participants considered medical follow-up useful and 91.5% wanted it to be conducted at all levels of health care. According to 93% of them, all health care providers should be involved. However, almost two-thirds (65.5%) had never been trained to use the child’s health record. About half (54.2%) of them had already seen the national manual and only 43.7% had ever filled it out, 82.2% of whom found it very difficult. With regards to the assessment of the content, 44.4% to 57.7% of respondents were dissatisfied with 12 of the 16 subheadings of the handbook. As for an ideal child health record, the majority recommended that it should contain indicators related to: childbirth, growth, monitoring of preventive activities and advice to parents. Conclusion: Child health booklets available in health facilities in Cameroon are not optimally used to reduce infant and child morbidity and mortality. It is important to review the content of the child’s health booklets in order to adapt it to the Cameroonian context.

摘要： [Objectives]The paper was to explore the spatio-temporal evolution of habitat quality in inland ecosystem.[Methods]Using landscape pattern analysis and InVEST habitat quality model,the land use change,landscape pattern and habitat quality change in Yunnan Province from 1980 to 2020 were studied.[Results]The land use change in Yunnan Province was relatively stable,and the forest land area accounted for 57.2%of the total area.The landscape fragmentation index caused by artificial surface encroachment on ecological land was increased by 6.33%,and the landscape heterogeneity was enhanced to varying degrees.The mean patch area was decreased by 5.83%,the number of patches was increased by 6.29%,and the degree of fragmentation was deepened.The habitat quality in Yunnan Province showed a"high-low-high"distribution from northwest to southeast,and the overall habitat quality was above the average.It is necessary to formulate optimization strategies to improve the regional ecological environment and realize the ecological system protection and rational land use in Yunnan Province.[Conclusions]The results will provide a scientific reference for regional ecological protection construction and land use planning in Yunnan Province.

摘要： This article briefly analyzes the significance of the penetration of traditional Chinese virtue education in vocational English teaching,focusing on how to combine Chinese traditional virtue education with vocational education.The the author proposes specific suggestions and counter measures for the effective integration of Chinese and international moral and English teaching.The author points out that vocational English teaching should not only improve the ability of vocational students’listening,speaking,reading,and writing,but also pay attention to permeating Chinese traditional virtue education in the classroom of English teaching,so that they are deeply integrated,and finally let us students in vocational colleges be internalized and externalized.This will provide a certain reference for the majority of vocational English teaching workers.

摘要： As part of a collaborative project,we took the window shutter—a widely used traditional facade element—and reinterpreted it for“adaptive”solutions using new,sustainable technologies.The aim was to design a modular construction kit that varies radiant energy,light and air flow to weather conditions and occupant requirements in new and existing residential and office buildings.

摘要： The analysis of satellite images is of fundamental importance in relation to understanding the evolution in land use.The general objective of this study is to analyze the changes in characteristics of rural land use in the municipality of Carazinho(RS)from 2001 to 2020 through the analysis of images taken from the Landsat TM-7 and TM-8 satellites.The TM-7 and TM-8 satellite images were classified and supervised,thus generation thematic maps with the following groups:tillage,forest,water resources and exposed soil.The analysis of this study showed that in 2001 the tillage group had an area of 10,651.6 ha,the forest group had an area of 7,248.03 ha,the water resources group occupied an area of 1,444.96 ha,and the exposed soil group occupied an area of 6,798.75 ha.When using the images taken in 2020,the same area presented the following data:the tillage group with an area of 15,941.5 ha.(60.95%),the forest group with an area of 4,320.99 ha(16.52%),water resources group with an area of 141.02 ha(0.53%),and the exposed soil group with an area of 5,747.22 ha(21.97%).The results demonstrate changes in land use during the study period,mainly with regard to the increase of cultivation areas and,consequently,the suppression of vegetation.

摘要： The abundance of social networking platforms has increased the frequency and the availability for which individuals communicate with one another. The feasibility and accessibility to go online to find sexual partners pose opportunity for contracting sexually transmitted infections (STI) in the absence of safe sexual practices. Low condom use has been reported among young adults who seek sexual partners online. African American young adults have some of the highest rates of infection for certain STIs. In order to mitigate the incidence and prevalence of STIs in at-risk populations, sexually active young adults must use condoms consistently and correctly during sexual activities. The present study sought to uncover the heterogeneity within African American young adults regarding their online networking utilization, STI knowledge, and sexual risk behavior. African American young adults (N = 236), ages 18 - 23, completed private online survey administration. Using latent class analysis, three classes were identified: Social Network Communicators (43%;N = 101), Social Networking Daters (36%;N = 83), and Media Sharers (21%;N = 52). Social Networking Daters exhibited the highest probability of using online dating sites daily, low STI knowledge, and a zero probability of consistent condom use. All three groups exhibited relatively low STI knowledge. Furthermore, having a history of STI increased the likelihood of being classified into the Social Networking Daters class relative to the other classes. Findings highlight the need to capitalize upon online platforms for African American young adults who utilize online dating sites and other online environments.
