Impact of Genetic Algorithm for the Diagnosis of Breast Cancer: Literature Review  [PDF]
Abebe Alemu Balcha, Samuel Alemu Woldie
Advances in Infectious Diseases (AID) , 2023, DOI: 10.4236/aid.2023.131005
Abstract: In recent research from the total number of new cancer cases in Africa about 29.46% and in Ethiopia 31.85% are breast cancer cases. 25.84% of all cancer related death is from breast cancer. One of the challenges in the treatment of breast cancer is early detection. Researchers agreed that, improving the preventive mechanism of breast cancer is an early predicting and detecting model. Research efforts are continuing to present different solution approaches using advanced techniques of Artificial intelligence (AI), Machine learning (ML), Deep Learning (DL), and Computational Intelligence as well. A genetic algorithm is a hyper-parameter optimization algorithm that belongs to the class of evolutionary algorithms. Genetic Algorithm (GA) is used for complex search spaces for search and optimization. This reviewed literature paper shows the positive effect of GA in the diagnosis of breast cancer on AI algorithms.

Anshebo Getachew Alemu, Teketel Alemu
Advances in Materials Physics and Chemistry (AMPC) , 2021, DOI: 10.4236/ampc.2021.114008
Abstract: Scanning electrochemical microscopy (SECM) feedback mode has been used to investigate regeneration kinetics on P1 (4-(bis-{4-[5-(2,2-dicyanovinyl) thiophene-2-yl] pH-enyl} amino) benzoic acid) dye sensitized nickel oxide (NiO) electrodes in contact with reduced iodide liquid electrolyte in different electrolyte solvents. We were used acetonitrile, ethanol, methanol and propylene carbonate solvents for comparison under illumination of different wavelengths. We found significant variation of regeneration kinetics parameters such as regeneration rate constant (keff), the reduction rate constant (kred) and absorption cross-section (Φhv) in different illumination intensity and different solvents.

Daniel S. Alemu
Open Journal of Leadership (OJL) , 2016, DOI: 10.4236/ojl.2016.51001
Abstract: In an extension of studies on dysfunctional organizations, vis-à-vis leadership, the current research examines leaders of dysfunctional and functional organizations in view of the functions of leadership. Sixteen variables related to leadership functions were tested to examine the relationship between leadership and organizational level of functionality and the differences between the characteristics of leaders of functional and dysfunctional organizations. A strong positive correlation was found between effective leadership and organizational level of functionality and a statistically significant difference was found between the characteristics of leaders of functional and dysfunctional organizations.
Integrated Watershed Management and Sedimentation  [PDF]
Molla Mekonnen Alemu
Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.74043
Abstract:

Environmental development and protection measures such as feasibility studies, land-use planning and soil and water conservation are some of the issues that need to be considered in watersheds management. Apparently, integrated watershed management is emerging as an approach for the sustained development and management of natural resources. The integral enactment of different environmental frameworks, strategies and policies could positively impact watershed- based developmental approaches. Sediment which is brought through water erosion can hamper the proper functioning of waterways as well as the quality of water in dams. Knowhow on soil erosion and the sedimentation process is among the requisites that need to be considered for the control of sedimentation. Other elements like climate, edaphic factors, land management, topography, and land cover, etc. will also determine the sedimentation process. Integrated Watershed Management approach is a worthy approach to manage the ecological, social and economic watershed development challenges in countries like Ethiopia. Thus, this article is intended to assess watershed characteristics that will help to explore the possibilities of reducing sedimentation and its related effects.

Sustainable Land Management  [PDF]

Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.74045
Abstract:

In one way or another, one out of three people are being affected by land degradation. It is estimated that, about every year, 75 billion tonnes of soil material are being lost worldwide as a result of land degradation. Recent findings also showed that about 2 billion hectares of land were severely degraded, in some cases in an irreversible way, all these caused a severe damage to local ecologies as well as contributed a lot for climate change and its associated effects on the wellbeing of humanity. Apart from this, the major portion of most developing countries population are still dependent on the un-mechanized and primitive forms agriculture, livestock production, forestry and fishery, and their livelihood and options for economic development are directly linked to the quality of the land and its resources. The objective of this article is to reaffirm the role of Sustainable Land Management in the process of agricultural development, the main source of livelihood in the developing countries. The paper initially explored the basic concept and principles of sustainable management. Causes of land degradation, the prime challenge of sustainable land management and development are also dealt in detail.

Mulugeta Dalbo, Alemu Tamiso
Advances in Infectious Diseases (AID) , 2016, DOI: 10.4236/aid.2016.62010
Abstract: Background: Despite increased deliverance of antiretroviral therapy (ART), morbidity and mortality from TB are still predominant among HIV/AIDS infected patients in Ethiopia. Thus, current study aimed to determine magnitude and predictors of tuberculosis among cohort of HIV infected patients at Arba Minch General Hospital, Ethiopia, 2015. Methods: Hospital based retrospective follow-up study was conducted among study population which was HIV/AIDS infected individuals registered from September 2007 to 2013. The data were collected using structured data abstraction form and four ART trained nurses were used to abstract the data. The data were checked for completeness, cleaned and entered into Epi Info 7.0 and analyzed using SPSS version (IBM-21). Results were summarized by using table of frequency, graph, and measure of central tendency. Statistical significance was inferred at P-value ≤ 0.05. Adjusted odd ratio (AOR) with 95% confidence interval (CI) was used to determine predictors. Result: Four hundred ninety six patient’s charts were abstracted. Cumulative and incidence density of tuberculosis were 21.4% (95% CI: 21.3, 21.44) and 5.36 per 100 person year respectively. Cigarette smokers (AOR: 2.82, 95% CI (1.27 - 6.27)), household with family size of 3 - 4 (AOR: 2.26, 95% CI (1.14 - 4.50)), baseline WHO clinical stage III (AOR: 20.26, 95% CI (7.09 - 57.6)) and IV (AOR: 22.9, 95% CI (6.91 - 76.4)) and heamoglobin level of <10 (AOR: 2.56, 95% CI (1.22 - 5.33)) were important predictors (risk factors) of tuberculosis among HIV

Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.710112
Abstract: Household energy demand is among the prime problems that cause deforestation. The use of fuel wood in the developing countries of Africa, Asia and Latin America is be-lieved to play a key role for the razing of forests and the degradation of associated biodiversity and other land resources. High population growth, increased energy demand, urbanization, infrastructure development, etc. are among the factors that exacerbate the current rate of deforestation in Ethiopia. This growing demand is also posing a threat to the remaining natural capital and associated wildlife of the country’s national parks. NechSar national park, a jewel in the Rift Valley of Ethiopia is not in different to this threat. The issue is calling for an urgent interference in the provision of environment friendly energy sources, afforestation programmes, raising the level of awareness on climate change, etc. This study is therefore, aimed at exploring the level of household energy demand interference on the woody vegetation of NechSar Park and promoting the use of environment friendly and energy saving technologies in the vicinity of the park area and beyond.

Melku Dagnachew Alemu
Agricultural Sciences (AS) , 2019, DOI: 10.4236/as.2019.1011103
Abstract: In this study, the roles of indigenous knowledge and farmers’ perception of natural resources management were analyzed. A total of seventy households were selected by simple random sampling with replacement method for collection of data. Formal interviews were conducted to the 5% plus of households in the study area in addition to the focus group discussions and qualitative field observations. It was expressed by 98.6% of the total respondents that “Sera” which is the traditional practice has being used to manage natural resources in the study area. In the “Sera” systems, individuals are excluded a punishment from any kind of social interaction in a response to their unlawful action in the community natural resources. It was indicated by 84.3% of respondents that deforestation and related problems are the major challenges including grazing and shortage of farm size for the management of the culturally protected forest in the study area. The majority of the respondents (77.1%) believed that soil fertility decline in the study area. Development of effective participatory forest management and encouragement and supporting the traditional method of natural resources management is required to ensure the preservation and protection of these areas essential to ecosystem service provision, provide high biodiversity value and cultural heritage, and maintain the sustainability of culturally protected forest.

Abstract: Growing body of epidemiologic evidence suggests that there are a number of modifiable risk factors that lead to increased incidence of hypertension in low income countries. Besides non modifiable factors like age, highly active antiretroviral treatments are believed to be increase the risk of hypertension in Human Immuno Virus patients. But studies disagree as to whether there are a greater incidence of hypertension among HIV/AIDS patients and the role of antiretroviral therapy. The Study was conducted in public health institution of Gamo-Gofa zone by using Retrospective cohort study design. Simple random sampling techniques with stratified sampling with proportional to size allocation were used to select HIV patients. The data were collected by registered Anti Retroviral Treatment Provider nurses, by using structured questionnaire which was adapted from the World Health Organization STEPS instrument. The data were cleaned to check for its completeness, consistency and the presence of missed values and variables, and then it was entered into a pre-designed format in Epi-Info version 7 and transferred to SPSS version 21 and Stata for further analysis. Frequencies, mean, median, quartile and standard deviation were used to describe the data. After necessary assumption of logistic regression model was checked, bivariable and multiple logistic regression models were fitted to see the predictors of hypertension. A total of 834 HIV/AIDS infected (95.4% response rate) were included in this study. The mean systolic and diastolic BP were 115.7 mmHg (±16.1 SD) and 74.9 mmHg (±12.4 SD). The cumulative incidence of hypertension was 20% (95% CI: 19.9 - 20.03), in equal proportion in Pre-HAART (20.1%) and HAART (20.0%) receiving patients. The study revealed modifiable; monthly income (AOR; 2.26, 95% CI (1.26, 4.05)), Occupational status (AOR, 0.36, 95% CI; (0.17, 0.78)), Body mass index (AOR: 12.6, (95% CI: 5.32, 29.8)) and non-modifiable family history of hypertension (AOR: 2.18, 95% CI: 1.32, 3.58) as important predictors of hypertension among HIV infected patients. There was high incidence of hypertension among HIV infected patients which may reflect insights for intervention. The investigators accept the null hypothesis that there is association between HAART intervention and incidence of Hypertension.

Advances in Infectious Diseases (AID) , 2020, DOI: 10.4236/aid.2020.103015
Abstract: On 30 January 2020 World Health Organization (WHO), declared the novel corona virus as a Public Health Emergency of International Concern (PHEIC), COVID-19 virus as an epidemic transmitted virus. It was on 31 December 2019, the WHO China Country office was informed the cases of pneumonia unknown etiology detected in Wuhan city, Hubei Province of China. Just after WHO’s declaration, Ethiopia has taken different measures to protect from this public health emergency problem. The disease is human to human transmitted virus. It comes from outside of the country, so that it opens check points in different entrance of the country. However, in 13 March 2020 the first positive case was reported from Japanese man. The virus is continuing the transmission in the public progressively more. While this research has been working, within 90 days from the first case, the country reported 2506 positive cases, 35 deaths. The research has done after collecting the first 90 days of data in Ethiopian case. Daily report announced by Ethiopian MoH is based on the test. And hence, the reported data as positive cases with COVID-19 is not actual positive case data in the country. There for, this paper has contribution for planning and taking further measure on the viruses by demonstrating the next 90 days predictive data. I use best curve fitting analysis using python function of the module polyfit algorithm to predict the trend of COVID-19 cases in Ethiopia.
