  • This study proposes strategies for economic development through mobile in Africa where mobile emerges as an infra to solve socioeconomic problems. It analyzes economy and ICT industry in Africa and studies several cases that are utilized in agriculture, finance, education, and healthcare. It also examines economic development theory and the impact of broadband on economic growth and development. It is necessary to leapfrog to mobile to achieve an information society and a compact industrialization based on ICT because fixed-line is very poor and expensive in Africa. Building a mobile broadband infra, supporting a dissemination of low-end smartphones and a government's support for mobile contents are necessary to achieve a leapfrogging development through mobile in Africa. The findings of this study provide additional insights for Korean ICT companies to consider a business in Africa.

  • This study has the purpose of geopolitical analysis on the role, function and problem of (trans) frontier park in Southern Africa. Frontier parks in Southern Africa had been used as a buffer zone between colonial empires and British colonial administration during the colonial period and as an interdiction zone of communism and black liberation movement during the apartheid regime, the cold war and the civil war. The ecological transfrontier peace parks in Southern Africa which is integrating the adjacent Frontier parks is utilized as a means of a conflict resolution and peace building after the end of cold war, civil war and apartheid regime, The ecological transfrontier peace parks in Southern Africa is very highly regarded as an effective means for a conflict resolution and peace building. But it is also being criticized for a reproduction of South Africa's politico-economic domination and of a socio-spatial division between racial groups.

  • Genetic diversity of sub-Saharan African goats was assessed using 19 microsatellite markers. Breeds were sampled from eastern Africa (Maasai, Kigezi, Mubende, North West Highland, Arsi-Bale), southern Africa (Ndebele, Pafuri) and West Africa (West African Dwarf, Maure, Djallonke). European breeds (Grisons Striped, Toggenburg), Asian breeds (Mongolian Cashmere, Bandipur) and a Middle East breed (Arab) were also included. The mean number of alleles per locus and average gene diversity ranged from 5.26$\pm$0.464 (Djallonke) to 7.05$\pm$0.516 (Mubende) and from 0.542$\pm$0.036 (Pafuri) to 0.672$\pm$0.031 (Ndebele), respectively. The between breeds variation evaluated using $$G_{ST}$$ and $\theta$ were found to account for 14.6% ($\theta$) and 15.7% ($$G_{ST}$$) of the total genetic variation. The $D_{A}$ measure of genetic distance between pairs of breeds indicated that the largest genetic distance was between Pafuri and Djallonke while the lowest genetic distance was between Arsi-Bale and North West Highland. A neighbour-joining tree of breed relationships revealed that the breeds were grouped according to their geographic origins. Principal component analysis supported the grouping of the breeds according to their geographic origins. It was concluded that the relationships of sub-Saharan African goat breeds were according to their geographical locations implying that the goats of eastern Africa, West Africa and southern Africa are genetically distinct. Within each sub-region, goat populations could be differentiated according to morphological characteristics.

  • Capsicum frutescen is known in Sudan, is one of the most commonly used pepper species in cooking and in Sudanese folk medicine. The present study was conducted to investigate antimicrobial (bacteria and fungi) and cytotoxicity (Brine Shrimp Lethality Test) of methanolic extract of Capsicum frutescen (fruits). The extract have been tested in the present study to investigate the in vitro potential effects against Gram positive, Gram negative bacteria and fungi. The selected organisms were Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia and Candida albicans using the cup plate agar diffusion method. The methanol extract of Capsicum frutescen (fruits) exhibited inhibitory effects against Escherichia coli with zone of inhibition (23 mm) and Klebsiella pneumonia with zone of inhibition (17 mm). The phytochemical screening revealed the presence of Tannins, Saponin, Alkaloids, Anthroquinoles and Terpenoids. The Cytotoxicity of methanolic extract of Capsicum frutescens was $LD_{50}$ $64.68{\mu}g/ml$. The activity and presence of compounds known to be biologically active are a validation for the use of Capsicum as a food ingredient and as a therapeutic element of traditional medicine.

  • African breast cancer patients benefit less from classical pathology services owing to the complex molecular and clinicopathological nature of the disease, poor quality of laboratory supplies, and shortage of experts in the field. This review presents evidence and confirms the need for improving anatomic pathology services in Africa. Peer-reviewed international journal articles available in Medline, Scopus, PubMed, and Google scholars, describing the status of pathology services in Africa, were included. Besides the late presentation of patients, anatomic pathology laboratories are accountable for the escalated mortality of breast cancer patients in several parts of Africa. Conversely, molecular diversity and biological heterogeneity of breast cancers, which disprove the one-size-fits-all therapeutic approach, have been reported from different parts of the continent. Irrespective of the geographical background, the choice of therapeutic options and predicting disease outcome depends on the right identification of the molecular signature of the cancer type. In conclusion, we propose that upgrading and integrating anatomic pathology with molecular diagnostic pathology is essential in order to provide better diagnostic results that will profoundly impact curbing mortality from breast cancers.

  • Purpose: Although long-term viral suppression and antiretroviral therapy (ART) success depend on sustained adherence, adolescents' adherence rates are suboptimal. Optimal adherence is influenced by various factors. Since Sub-Saharan Africa is home to over 80% of adolescents living with human immunodeficiency virus (HIV) and considering their unique characteristics and susceptibility to poor adherence, it is crucial to provide updated knowledge on adherence rates and their determinants among this population. This review aims to present up-to-date data on adherence rates and associated factors among HIV-positive adolescents in Sub-Saharan Africa. Methods: A systematic review was conducted following the PRISMA guidelines. The PubMed and Scopus databases were used to identify documents corresponding to the study's objectives. Eleven studies were included in this review after being selected from among all studies that were found online from 2017 to 2023. Results: The reported adherence rates ranged from 55% to 86%. In total, 32 factors were found to be related to adherence among HIV-positive adolescents in Sub-Saharan Africa. These included 12 adherence-facilitating factors and 20 adherence-inhibiting factors. The most often mentioned factors affecting adherence were advanced World Health Organization clinical stage (i.e., stage IV), ART dose and regimens, a lack of support, and violence victimization. Conclusion: Our findings can help healthcare providers collaborate with HIV-positive adolescents to improve ART adherence and ensure the best possible health outcomes.

  • An eight-year old neutered male miniature pinscher dog was referred with a mass on the right frontal region. Radiography, computed tomography (CT) and magnetic resonance imaging (MRI) examination were performed. Imaging results showed mineralized mass invaded frontal bone without brain parenchymal change and distant metastasis. The mass was removed mostly by surgical resection, and the dog was discharged without any complications. On the histopathological examination, the mass was diagnosed as grade I multilobular osteochondrosarcoma. Though the mass recurred after the surgical resection, the dog is still alive to date without metastasis.

  • Recently Korean construction companies have started launching into the world beyond the Middle East to Southeast Asia. Launching into Central Africa has emerged as the blue chips; therefore, it is needed to study the local people and culture of Central Africa. However, launching Korean construction companies into Central Africa may cause some problems between Korean and African construction laborers' thinking. Therefore this comparative analysis of Korean and Central African construction laborers' job consciousness can provide to Korean companies a minimum understanding of these kinds of problems to expect while launching into Central Africa and so using this analysis as a basic data to supply them.
