Background As the most basic unit of infectious disease prevention and control, community health service institutions are the frontline and important gateway for the prevention and control of infectious disease. Primary care physicians are responsible for epidemic surveillance, vaccination, health promotion and assistance to centers for disease control in investigating and disposing outbreaks and public health emergencies in their districts, and play an active role in disease prevention and control by groups, susceptible population protection, infectious source control and health education, as well as the effective prevention and control of infectious diseases. Objective To understand the ability of primary care physicians to diagnose and treat infectious diseases in the community, analyse their existing problems and shortcomings, design and conduct a series of intensive training related to infectious diseases for improving the capacity of infectious disease prevention and control at the primary level; To evaluate the effectiveness of online continuing medical education, so as to provide a reference for better continuing medical education on infectious diseases in the community. Methods All participants of the National Community Infectious Diseases Continuing Education Conference held by the Department of Family Medicine of the University of Hong Kong-Shenzhen Hospital in November 2021 were selected as research subjects from November 2021 to March 2022. The questionnaires were distributed to all registered attendees before and after the conference through the QR code of the questionnaire star, and the content of pre-conference questionnaire included demographic characteristics of the participants, participation in infectious disease training in the community since started working, diagnosis and treatment of infectious diseases in the community, subjective attitudes towards the prevention and control of infectious diseases in the community (willingness to manage infectious diseases in the community, satisfaction with their own infectious disease management skills), expertise in infectious disease prevention and control and knowledge related to conference content, attitude towards hepatitis B. The content of the post-conference questionnaire mainly included knowledge about the content of conference, attitude towards hepatitis B and satisfaction survey of this online conference. A total of 301 primary care physicians completed the questionnaire before and after the conference, and a total of 194 completed the questionnaire before and after the conference. Results Among all participants, 166 (55.1%) had attended infectious disease training in the community, of whom 49 (29.5%) were satisfied with their infectious disease diagnosis and treatment ability; 135 (44.8%) had not attended the training, of whom 22 (16.3%) were satisfied with their infectious disease diagnosis and treatment ability. 143 (86.1 %) of 166 participants who had attended infectious disease training in the community indicated their willingness to manage community infectious diseases, 99 (73.3%) of 135 participants who had not attended infectious disease training in the community indicated their willingness to manage community infectious diseases. 66 (27.3%) of participants who were satisfied with their infectious disease diagnosis and treatment ability indicated their willingness to manage community infectious diseases. The top three infectious disease tests conducted by the institutions were hepatitis B, AIDS, and hepatitis C; the top three infectious diseases treated in the past six months were hepatitis B, influenza, hand, foot and mouth disease. Different self-evaluation and willingness to train may affect the willingness to manage community infectious diseases (P

Sexual health is an important component of human health. Ignoring, misunderstanding and having misconceptions of sexual health will greatly impair people's quality of life. Owing to the concept of holistic health in general medicine, influence of biopsychosocial model of health, and family as a vital unit of care, and adherence to protecting patient privacy as a professional responsibility, general practitioners (GPs) have obvious advantages in offering sexual health services. However, more efforts are needed to strengthen the promotion of sexual healthcare knowledge popularization, sexual health screening, and sexual problem diagnosis and treatment in primary care of China. To provide support for Chinese GPs to deliver sexual health services, Department of General Medicine, the University of Hong Kong-Shenzhen Hospital, has pioneered in providing sexual health services and exploring new service delivery models using actions such as constructing a sexual health service team and a genital examination skills workshop, carrying out the consultation about sexual history, and developing a standard diagnostic and therapeutic procedure for sexualproblems.

Full waveform inversion (FWI) is a high-resolution technique to estimate the parameters of dielectric permittivity (ϵ) and electrical conductivity (σ) and identify the structure of the subsurface for Ground Penetrating Radar (GPR) application. However, permittivity and conductivity parameters can be coupled in bi-parameter GPR inversion. This coupling effect leads to the crosstalk in the FWI result. To solve this problem, we propose a novel approach to use the multi-scale FWI with the hybrid regularization method, which combines Tikhonov and total-variation (TV) regularizers that simultaneously invert the ϵ and the σ parameters, which improve the inversion accuracy and reduce the crosstalk effect. The multi-scale strategy uses the Wiener filtering to process the GPR data in different frequency ranges. Then, the low frequencies signal updates the bottom part and subsequently increases the frequencies to invert for the shallow areas. The Tikhonov regularization stabilizes the reconstruction of the smoothly varying background part. In contrast, Total Variation (TV) regularization can recover the large contrasts associated with the LNAPL model. The new Tikhonov-TV (TT) regularization can mitigate the crosstalk caused by the parameter coupling effect. Numerical tests with typical GPR models demonstrate that the proposed multi-scale TT-FWI strategy can effectively eliminate the crosstalk and improve the reconstruction accuracy when the model parameters have a different structure.

Aiming to clarify the effect of Lactobacillus plantarum combined with distiller's grains biochar on lead, cadmium and zinc complex contaminated soil, a pot experiment was conducted to investigate soil effective heavy metal concentration, plant growth, and heavy metal accumulation in the Sorghum hybrid sudangrass. The results revealed that single application of distiller's grains biochar, Lactobacillus plantarum thallus, Lactobacillus plantarum supernatant, and combined application of distiller's grain biochar and Lactobacillus plantarum thallus could significantly reduce the content of available Cd, Pb, and Zn in soil (P

Background: Students' music self‐concept and music emotions are becoming prominent topics within the area of music education. Aims, Samples and Methods: The majority of previous research on self‐concept and music emotions has examined the two constructs independently and focused on gender differences in externalizing behaviours in music learning, but has neglected the internal interactions between individual music self‐concept and music emotions. Network analysis is a promising method for visually examining music self‐concept and music emotions as part of a network of interactions to identify core features and interrelationships among nodes in the network. In this study, 515 students majoring in music from a Chinese university were recruited. Results: The results showed that high music self‐concept and boredom were the common features at the core of the network for both men and women college students. The boredom exhibited by women differed from that of men in that men's boredom was directed at the entire music course, while boredom in women manifested as daydreaming and boredom with learning materials. Conclusions: This study is the first to explore gender differences in the music self‐concept and music emotions from a holistic perspective. The findings could help music teachers gain insight into the complex system of music self‐concept and music emotions. Music teachers could capture the respective features of men and women to design individualized teaching strategies. [ABSTRACT FROM AUTHOR]

Satellite imagery has been widely used to monitorthe extent of environmental change in both mine andpost mine areas. This study uses Remote sensing and GeographicalInformation System techniques for the assessmentof land use/land cover dynamics of mine relatedareas in Wa East District of Ghana. Landsat satellite imageriesof three different time periods, i.e., 1991, 2000 and2014 were used to quantify the land use/cover changes inthe area. Supervised Classification using Maximum LikelihoodTechnique in ERDAS was utilized. The images werecategorized into five different classes: Open Savannah,Closed Savannah, Bare Areas, Settlement and Water. Imagedifferencing method of change detection was used toinvestigate the changes. Normalized Differential VegetativeIndex valueswere used to correlate the state of healthyvegetation. The image differencing showed a positive correlationto the changes in the Land use and Land coverclasses. NDVI values reduced from 0.48 to 0.11. The landuse change matrix also showed conversion of savannahareas into bare ground and settlement. Open and closesavannah reduced from 50.80% to 36.5% and 27.80% to22.67% respectively whiles bare land and settlement increased.Overall accuracy of classified 2014 image andkappa statistics was 83.20% and 0.761 respectively. Thestudy revealed the declining nature of the vegetation andthe significance of using satellite imagery. A higher resolutionsatellite Imagery is however needed to satisfactorilydelineate mine areas from other bare areas in such Savannahzones.
