The history of mankind contains so many illustrations of well-classified and violent struggles against various animals over crop production in agricultural fields, attacks on human life or competition in order to have access to certain natural resources. The aim of this study is to characterise the human-wildlife conflicts that occur around the KBNP, especially with regard to primates. Surveys were carried out in 260 households selected using the snowball method. The results showed that human-wildlife conflicts around the KBNP are characterised by the destruction of crops in riparian fields by monkeys, chimpanzees and gorillas, the destruction of houses, physical attacks and zoonoses. Despite the conservation and protection measures for wildlife and local populations put in place by the Park’s managers, conflicts between local populations and the Park’s wild animals are still visible. These conflicts lead to the detention of wild animals by local people roaming in the villages and to poaching on the Park’s boundaries. The weakness of the community management policy on the part of the park managers and the resentment of the indigenous peoples towards the restriction of their access to natural resources are the major constraints on the sustainable management of conflicts between the local populations and the wild animals in the KBNP. The strategies for the sustainable resolution of human-wildlife conflicts around the KBNP must be geared towards and integrated into a community conservation approach.

Background: Prostate cancer, the most common male cancer, represents a real public health problem in terms of its frequency and severity in different countries around the world. It disproportionately affects people of African descent wherever they live in the world [1]. To the best of our knowledge, its extent and particularities in the African environment are not well known. Objective: To determine the epidemiological and histopathological profile of prostate cancer in the CUK anatomopathology department. Methodology: This is a retrospective study conducted at the University Clinics of Kinshasa Anapathology Department from January 1, 2015 to December 31, 2022, a period of 8 years. Word processing and tables were entered using the Hp brand computer, with Microsoft Office WORD 2016 software. Data analysis was performed with SPSS version 22.0 software. Results were presented in tables and figures. Results: Prostate was diagnosed in 132 cases, i.e. 1.58% of all CUK laboratory analyses and 8% of cancers diagnosed. The age group most affected was 66-75 years, i.e. 59% of all subjects. Adenocarcinoma was the most frequent histological type, and biopsy dominated in 111 cases (84.1%). Conclusion: Prostate cancer is a real public health problem. Worldwide, and in the Democratic Republic of Congo, it is the most frequently diagnosed cancer in men, and the leading cause of cancer-related death in men. In the DRC, because of the delay in consulting our patients and the weakness of systematic screening, patients are seen at an advanced stage of the disease. Treatment is multidisciplinary, involving surgery, radiotherapy and chemotherapy (including targeted therapies). Patient awareness and screening campaigns will help to considerably reduce the delay in diagnosis and the morbidity and mortality associated with prostate cancer.

Gd_(0.67)Ca_(0.33)MnO_3(GCMO)thin films grown by laser ablation on SrTiO_3(100)(STO)substrates was studied. Films are highly crystallized, very well epitaxial and single-phased. The ordering magnetic temperature(T_c)of the films is much higher than the value of bulk samples of similar composition. It is found that the GCMO film exhibits a reversal of its magnetization at low temperature when cooled under a magnetic field. The negative magnetization is a consequence of the rapid increase(～1/T)with decreasing temperature of the magnetization of a sublattice aligned antiparallel to the local field, relative to the magnetic contribution of a second sublattice which is aligned parallel to the applied field.

一年前,ChatGPT的突然兴起让所有人措手不及,引发了社会各界从惊叹到恐慌的一系列混乱反应。尽管我们都意识到这一天迟早会到来,但社会显然还未作好充分准备来应对这种新型智能的挑战。生成式人工智能大规模应用于广泛多样化任务的潜力令人震撼,然而,这些潜在应用所引发的主要是普遍的恐惧情绪。其中的核心问题是,我们很难理性地讨论人工智能的能力范畴。这种困难在很大程度上源于我们与生成式人工智能之间缺乏有效的交流与沟通机制。沟通需要共识。
