With the increasing global focus on renewable energy, distributed rooftop photovoltaics (PVs) are gradually becoming an important form of energy generation. Effective monitoring of rooftop PV information can obtain their spatial distribution and installed capacity, which is the basis used by management departments to formulate regulatory policies. Due to the time-consuming and labor-intensive problems involved in manual monitoring, remote-sensing-based monitoring methods are getting more attention. Currently, remote-sensing-based distributed rooftop PV monitoring methods are mainly used as household rooftop PVs, and most of them use aerial or satellite images with a resolution higher than 0.3 m; there is no research on industrial and commercial rooftop PVs. This study focuses on the distributed industrial and commercial rooftop PV information extraction method based on the Gaofen-7 satellite with a resolution of 0.65 m. First, the distributed industrial and commercial rooftop PV dataset based on Gaofen-7 satellite and the optimized public PV datasets were constructed. Second, an advanced MANet model was proposed. Compared to MANet, the proposed model removed the downsample operation in the first stage of the encoder and added an auxiliary branch containing the Atrous Spatial Pyramid Pooling (ASPP) module in the decoder. Comparative experiments were conducted between the advanced MANet and state-of-the-art semantic segmentation models. In the Gaofen-7 satellite PV dataset, the Intersection over Union (IoU) of the advanced MANet in the test set was improved by 13.5%, 8.96%, 2.67%, 0.63%, and 0.75% over Deeplabv3+, U2net-lite, U2net-full, Unet, and MANet. In order to further verify the performance of the proposed model, experiments were conducted on optimized public PV datasets. The IoU was improved by 3.18%, 3.78%, 3.29%, 4.98%, and 0.42%, demonstrating that it outperformed the other models.

Objectives: The study explores the relationship between social support, self-care ability, and life quality of cured leprosy patients (CLPs), aiming to develop strategies to enhance their overall well-being. Methods: From July to December 2021, we investigated the social support, self-care ability, and life quality of CLPs through three scales and analyzed the correlation between them. In addition, structural estimation modeling (SEM) was employed to analyze their correlation. Results: A total of 9245 CLPs were recruited, with a male-to-female ratio of 2.19:1, and 94.04% of cured patients was 60 years or above, with predominantly home-cured patients. The scores of WHOQOL-BREF, SSRS, and ESCA were (51.39 ± 9.89), (31.87 ± 8.76), and (100.95 ± 19.75), respectively. The results indicate a poorer quality of life and social support for CLPs compared to the general population in China. Furthermore, the home group had higher scores on these scales than the leprosarium group. The correlation analysis showed significant interactions between life quality, social support, self-care ability, and various domains (p < 0.05). SEM results revealed that the direct effect of self-care ability on life quality was 0.13, and the indirect effect on quality of life through social support was 0.08. The mediating effect of social support accounted for 22.86% of the total effect in the home group. In the leprosarium group, the effect of self-care ability on quality of life was 0.14. Conclusions: Most CLPs in Jiangsu Province are concentrated in the central region, with a high disease burden. We found that CLPs have a poorer life quality than the general population, with the leprosarium group being worse than the home group. The government and society should pay more attention to and support these cured patients.

Background: The study aimed to characterize patients with leprosy admitted to Fontilles throughout the 20th and 21st centuries, focusing on differences across three periods (I, II, and III). It also explored variables linked to patient survival. Methods: This was a retrospective descriptive study analyzing the medical records of Fontilles patients from 1909 to 2020. It assessed 26 clinical, sociodemographic, and temporal variables (n = 2652). Results: Most patients were male, single, multibacillary (MB), and farmers, from Andalusia and the Valencian Community. The origin of patients shifted over time towards being mostly foreign-born in period III. More than a half were previously admitted and had family members with leprosy. While leprosy reactions decreased over time, neurological symptoms were increasingly diagnosed. The age at onset, admission, and death increased progressively over time. The survival of patients with leprosy at Fontilles depended on the age at admission and the period. Conclusions: Improved knowledge, services, and awareness regarding leprosy led to increased age at onset and more favorable outcomes. The prolonged time between symptom onset and diagnosis indicates that leprosy is still a neglected disease. Although MB forms are more severe, leprosy classification did not significantly impact the survival rates of patients at Fontilles.
