Item Application of Case Based Recommender System in the Tourism Sector for the Selection of Tourist Attraction Areas in Ethiopia(Addis Ababa University, 2014-06-06) Anteneh, Tamir; Bekele, Rahel (PhD)The aim of this research is to design a prototype case based recommender system for tourist attraction area and visiting time selection that can assist experts and tourists to make timely decisions. For the development of case based recommender system, essential knowledge was acquired through semi-structured interview and document analysis. Eight domain experts and fourteen visitors were interviewed to elicit the required knowledge about the selection process of attraction area. The acquired knowledge was modeled using hierarchical tree structure and it was represented using feature value case representation. At the end, jCOLIBRI programming tool was used to implement the system. The main data source (case base) used to develop case based recommender system for tourist attraction area selection is previous tourist cases collected from NTO and MoCT. As a retrieval algorithm, nearest neighbor retrieval algorithm is used to measure the similarity of new case (query) with cases in the case base. Accordingly, if there is a similarity between the new case and the existing case, the system assigns the solution (recommended attraction area and visiting time) of previous case as a solution to new case. To decide the applicability of the prototype system in the domain area, the system has been evaluated by involving domain experts and visitors through visual interaction using the criteria of easiness to use, time efficiency, applicability in the domain area and providing correct recommendation. Based on prototype user acceptance testing, the average performance of the system is 80% and 82% by domain experts and visitors respectively. The performance of the system is also measured using the standard measure of relevance (IR system) recall, precision and accuracy measures, where the system registers 83% recall, 61% precision and 85.4% accuracy. Finally, conclusion and future research directions are forwarded.Item Application of Data Mining Technology to Support the Prioritization of Dangerous Crash Locations the Case of Addis Ababa Traffic Office(Addis Ababa University, 2009-01) Kiflu, Haleluya; Bekele, Rahel (PhD)The development of automotive industry, the slowly improvement of the roadways and the behavior of the traffic participants increased the number of the road accidents. Traffic accident results in loss of life, human injury and financial prejudices. Road Traffic Safety which is currently one of the highest priorities may be affected by a number of factors. One important group of bottlenecks in traffic safety are dangerous accident locations. Addis Ababa is a city where the number of traffic accident is increasing from time to time. Identification of high crash locations in the city will either protect the accident occurrences or minimize the rate of damage to be caused. This paper reports on the findings of a research that had the objective to prioritize high crash locations and predict exposure of the society on different crash locations. The study used data obtained from the Addis Ababa Traffic Office. In order to prioritize high crash locations different data mining tools and techniques were used. The data mining process in this research is divided into two major phases. During the first phase data was prepared and formatted into the appropriate format for the respective data mining software to be used (Weka 3.5.8). The second phase contains model building for prioritization using decision tree classification. In the classification phase J4.8 algorithm were employed to generate rules. Traffic accident locations were prioritized based on their degree and number of fatality occurrence. The patterns obtained from the J-48 algorithm separated these locations as: death, severe injury, and light injury.The outcome of the study is highly useful for the Traffic police office on developing traffic management system; for the society, drivers and pedestrians, on pre-informing the accident occurrences on those black spots. It also provides valuable information for making decisions effectively for road safety investment projects.Item Application of Data Mining Technology to Support the Prioritization of Dangerous Crash Locations the Case of Addis Ababa Traffic Office(Addis Ababa University, 2009-01) Kiflu, Haleluya; Bekele, Rahel (PhD)The development of automotive industry, the slowly improvement of the roadways and the behavior of the traffic participants increased the number of the road accidents.

The main objective of this study examined factors affecting user satisfaction with the ERP system usage. To address the purpose, this study developed a conceptual model based on DeLone and McLean IS success model and relevant prior studies which validated the effect of variables on the user satisfaction empirically in the local setup. A mixed research approach was used to collect data from the respondents; which supports to validate the research model and explore the in-depth understanding of the user perception. Correlation analysis and linear regression analysis was used to realize the association among constructs and to determine the predictive power of the variable respectively. The study found that the user satisfaction with ERP system usage is predicted via variables stated in the proposed conceptual research model. The results also confirm system quality, technical support, management support and social capital as significant antecedents that enhanced the user satisfaction. Besides, the findings suggest that in addition to DeLone and McLean IS success model constructs, a social capital and management support play a vital role in boosting user satisfaction with the ERP system usage.Item Bayesian Approach for Analysis of Road Traffic Accident (The Case of Addis Ababa(Addis Ababa University, 2009-01) Tabor, Alemayehu; Bekele, Rahel (PhD)Road traffic accidents are among the top leading causes of deaths and various levels of injuries in the world. Ethiopian is one of the developing countries where the situation is becoming worse and worse form time to time. The country is experiencing highest rate of such accident result in fatalities and a high economic loss. Addis Ababa, the capital city of Ethiopia, accounts for approximately more than 21% of the fatal accidents, 42% of the injury accident and 65% of the total accidents reported in the whole country. This thesis reports the study carried out to develop accident predictive models based on the data collected on road accident in Addis Ababa. The BN power predictor and constructor were used for prediction and model construction purposes respectively. As a result relating or finding interrelatedness between the road and traffic flow explanatory variables and building a significant accident predictive models was possible. In doing so the potential applicability of Bayesian network to help traffic accident data analysis in decision-making process was explored. In the thesis, the process of building a model using Bayesian network tools and techniques from historical road accident record data is explained. Different tools and techniques are also used for the purpose of data analysis. The methodology adopted consisted of basic steps of data collection in which all the records are selected and extracted from Addis Ababa traffic office; data preparation which includes tasks such as data transformation, deriving of new attributes, and handling of missing values, and finally model building and validation using the selected tools and techniques. In the first experiment, a best learned model that can classify accidents well with a better accuracy as serious, crash or property damage was selected and evaluated. The second experiment was also conducted after the necessary input of the domain experts is added. Experiment results reveal that the model built with mentioned techniques and tools are very much helpful in identifying the potential contributors or causes of this ever-growing challenge of the road transport in Addis Ababa and their interrelatedness. The whole research process can be a good input for further research works.Item Bayesian Network for Modeling Determinant Factors Influencing Offenders to Commit Crime (The Case of Addis Ababa Police Commission)(Addis Ababa University, 2009-01) Abrar, Mohammed; Bekele, Rahel (PhD)The identification of causes and phenomena associated with crime is one of the most popular goals in criminology, especially in view of its practical value and the belief that such identifications are useful when seeking to correct or control criminal behavior. The utility of discovering causes must, however, be qualified. Understanding and processing of offenders’ records is one method to learn about both crime and the individuals who involve in misdeeds so that police can take crime prevention measures accordingly. Though data on criminals are continuously being gathered, they are not effectively being utilized for extracting patterns that can be used for effective management of crimes. This is mainly due to the inadequacy of the human brain to search for complex and multifactor dependencies in data and the lack of objectiveness in such analysis demanded a computerized approach. Developments in the information and communication technologies have made it possible for organizations to collect, store and manipulate massive amount of data. One such development is Bayesian Network. In this study, the main objective of the research is to develop a predictive model for factors that constitute higher crime trends in Addis Ababa which makes use of Bayesian Network modeling techniques. For this purpose, published literatures in related areas have been studied together with the review of different Bayesian Network modeling approaches. Different tools and techniques supporting such task were examined by taking into consideration their application to the problem domain. In addition, an experiment is conducted to explore the potential of Bayesian IV network in modeling factors that constitute higher crime trend using personal identification record of criminals. For the purpose of the experimentation 1572 criminal records were collected from the Addis Ababa Police Commission. The records were manually and automatically further preprocessed to make them compatible with software used. Important attributes that are considered relevant for the constructing predictive model for higher crime trends were selected. After preprocessing the data, a learning classifier is used to learn from the training data and use this classifier to classify new data. A model is constructed for the best learned model from data. Based on the experimental data, a Bayesian performance prediction model was developed where 73.25 % prediction accuracy was first observed. Further experiments and modification of the prediction model increased the level of prediction accuracy to 75.78 %. Finally, Three Phase Dependency Analysis in particular and Bayesian network in general is found applicable for modeling determinant factors for higher crime trends.Item Bayesian Network for Modeling Determinant Factors Influencing Offenders to Commit Crime (The Case of Addis Ababa Police Commission)(Addis Ababa University, 2009-01) Abrar, Mohammed; Bekele, Rahel (PhD)The identification of causes and phenomena associated with crime is one of the mo s t popular goals in criminology, especially in view of its practical value and the belief that such identifications are useful w hen seek in g to correct or control criminal behavior.

It defines the major principles of the intended TVET development in the coming years. The main thrust of the strategy is that TVET development relies on an outcome-based system and dedicated and trusting cooperation among stakeholders. Objective The overall objective of the study is to assess and evaluate the existing Knowledge sharing practice and identify opportunities that improve knowledge sharing practices among TVET colleges in Addis Ababa. Methodology The study has followed a quantitative and qualitative methodology. A sample of 203 Trainers and Academic deans are selected using Stratified random sampling from 3 public and 3 private TVET colleges. Questionnaire is applied to assess knowledge sharing according to respondent’s opinions and perceptions regarding each of the cultural, organizational and technological factors and existing knowledge sharing practice. Result Academic staffs are aware of knowledge sharing. They also believe that knowledge is power and it can help their college to stay competitive in the TVET environment. Moreover, academic staffs agree that they should share their knowledge and best practices. Recommendation It is recommended that the TVET agency take initiative to put a system in place that facilitates knowledge sharing among TVET colleges. Further studies are also recommended to investigate more facts that facilitate knowledge sharingItem Cyber Hygiene Practices Amongst Employees of Ethiopian Commercial Banks(Addis Ababa University, 2020-03-03) Deferew, Biruk; Bekele, Rahel (PhD)The ever-expanding cyberspace bring benefits to the financial institutions and there is also threats of attacks through it. Cyber hygiene is like a human being keeping its own personal hygiene not to be exposed by any types of disease, the same is true for cyber hygiene; keeping aside the cyber threats and attacks away. The Ethiopian commercial bank experience insider attacks such as password theft and email phishing attack were observed. Security is a big problem and it needs a big emphasis so that the purpose of the study is to evaluate current cyber hygiene practices of the employees in the Ethiopian commercial banking industry. Quantitative research methodology was used to conduct this research. Among 18 Ethiopian commercial banks three banks (such as Dashen bank, Abay bank, and Commercial bank of Ethiopia) were selected by using stratified sampling and based on the year of core banking automation criteria. The research used convenience sampling method to identify the sample. The primary data collection instrument was selfadministered questionnaire which was adapted from related research. SPSS version 20 was used to for data analysis; the research was conducted at the head office and branch level of the selected banks. Even if the finding shows that there was a gap on computing cyber hygienic practices but there is an observation of a good cyber hygiene practice like that of users didn’t stick their password on the office desk, not shared their password and unauthorized person is not allowed to use their computer. Respondents assure that their bank have a clear, specific, formal and understandable ISSP. And its practices of the Ethiopian commercial banks and the respondents’ attitude was very good regarding the banks ISSP. The respondents underline that, there was lack of periodic formal cyber hygiene training. The finding of the study shows, the need for regular assessment and follow up so as to provide strategic and adequate training.Item Design and Development of Web Based Maternal and Child Nutrition Information System(Addis Ababa University, 2017-06) Habtamu, Tigist; Bekele, Rahel (PhD); Yirgu, Robel (PhD)Under nutrition is one of the leading causes of morbidity and mortality of children in most developing countries including Ethiopia. Maternal and child nutrition related issues are main concerns of mothers, family or care takers, health care providers, organizations and governments that work in the field of nutrition. Since nutritional information has significant role in the reduction of maternal and child malnutrition, it is important to avail relevant nutritional data on various media including the web to enhance the effort that the health sector is putting to reduce maternal and child morbidity and mortality. Therefore, this study is intended to design and develop web based maternal and child nutrition information system that give hands for the health sector effort towards the reduction of maternal and child morbidity and mortality. Interview and document analysis were used as main tools to capture the system requirement, and the data was analyzed using inductive approach .The project used selected artifacts of an object oriented system analysis and design technique to design the web based system. The finding of the study shows that there is low level of awareness in the community about maternal and child nutrition. The prime source of Information on nutrition during pregnancy and lactation were not health professionals at the maternal and child health department, instead, they get it from other pregnant women, family or friends. Therefore, availing information is one way of intervention which strengthen the availability of information in a feasible and cost-effective mannerItem Designing Electronic Key Performance Indicator Information System for Yekatit 12 Hospital(Addis Ababa University, 2015-06) Kebede, Getenet; Bekele, Rahel (PhD)Electronic key performance indicator information system (EKPIIS) is a computerized system of accessing the report of performance indicator in real time of hospital within a single practice. The content of an EKPIIS is analogous to the paper record, but the electronic format creates usable data in hospital status studies, improves the quality, reliability and timely report that create efficient communication among stakeholders and makes easier management of health plans and strategy. The research project endeavored to design and integrate those functions to pave the way for the implementation so as to achieve efficient flexible information system that offers the customer and staff better satisfaction. Phased development, Rapid Application Development (RAD) methodology of object-oriented approach was applied to the study of the design system.

The thesis attempts to look into teachers' computer skills, experiences on the use of computers for academic, teaching and learning activities in addition to their views on the integration of E-Learning at college level. The study conducted using self-administered questionnaires, interviews and informal discussions with teachers and administrators in five public TVET colleges namely Entoto, Misrak, Silkiness, Threadbare and General Win gate. The results of the study generally revealed that: the existing ICT facility for teachers in Ethiopian public TVET Colleges is generally low; there is a need to facilitate the public TVET colleges to use computers and other ICT resources to support teaching; the public TVET College teachers' knowledge and skill in the use of computers in teaching-learning environment is low and in all the colleges, there is no E-Learning Program that help teachers to improve their ICT knowledge and way of teaching. Finding indicated that the status of TVET colleges in the provision of ICT infrastructure and the culture of the TVET teachers' in utilizing the existing computers, connectivity, and digital contents in the actual teaching and learning of subject areas have to be developed. In line with the above findings and conclusions, it was recommended that much emphasis have to be given by the concerned bodies in facilitating the public TVET colleges with ICT tools and up-grading teachers' ICT know-how in line with the quick changing technology through the use of E-Learning programs so as to produce digitally literate technology minded skilled manpower to support the educational development process in Ethiopia.Item Evaluation of the Usability of Point Based Traffic Penalty Management System the Case of Federal Transport Authority(Fta)(Addis Ababa University, 2021-06-08) Yohannes, Nblle; Bekele, Rahel (PhD)System usability is the effectiveness, efficiency and subjective satisfaction when a particular user using a particular product with a specific task to complete in certain circumstances (International Standard ISO9241-11, 2010). Many researchers have used the aspects of usability in their system usability evaluation for some application software. According to literatures, among the prominent researchers in the field of system usability evaluation Nielsen (2003) defines usability as a quality attribute that assesses how easy user interfaces are to use. And many more scholars have forwarded different measuring frameworks/models. This study was employed to perform system usability evaluation for a specified product named ‘Point-based traffic penalty management system’. The researcher applied mixed methods approach. Both qualitative and quantitative data from primary and secondary sources were applied. The research design used in this study was descriptive research design which statistically explains what it is transparently. In this research design method, the researcher has gathered data in two ways: firstly, data collected from experts of the system and secondly ordinary day-to-day actual users of the system. Henceforth, the study was conducted based on expert-based system usability evaluation and user-based evaluation. The expert-based evaluation implemented the heuristic evaluation model while the user-based evaluation extracted three independent variables (i.e. learnability, efficiency and satisfaction) from the five system usability quality components (Nielsen, 2012) defined. Though, the research results from the two models were far from perfect, they both indicated the specified system scored higher concerning the measuring threshold. The study forwards a kind recommendation that system usability evaluation shall be incorporated in all parts of software (system) development life cycle (SDLC), since this study was conducted on the implemented system. This research was articulated based on a case-study (a system that was operational) which by default was effective. But, since such kind of study can be operated in any stage, the results of similar studies that can include all five quality components would be an entrance point to wider study area. In the end, this study implemented frameworks that can be easily applied into any kind of system usability evaluation considering its advantage in aggregating system utilization, avoiding possible system failure and unnecessary system related costs.Item Exploration study and design of a technology platform for knowledge sharing among health professionals to improve maternal and child healthcare.(Addis Ababa University, 2016-06) Amente, Obsa; Bekele, Rahel (PhD)Knowledge is a valuable asset for individual as well as organizations to be successful in this demanding global economy. The change of information into knowledge is mainly due to the effort of human cognitive capacity. Knowledge Management (KM) is therefore a conscious strategy of getting the right knowledge to the right people at the right time and helping people share and put information into action in ways that strive to improve organizational performance. KM includes processes like knowledge capture and/or creation, knowledge sharing and dissemination, and knowledge acquisition and application. The major aim of this project is to explore the knowledge sharing status and design knowledge sharing technology platform for health professionals working on maternal and child healthcare unit. A qualitative cross sectional case study design was conducted to gain insight; explore the depth, richness, and complexity inherent in the topic of interest. The hospital technical staffs working in MCH unit were included as study participants. An in depth interview guide was used to collect qualitative data. The collected data was analyzed manually using the thematic inductive analysis method. In this project/study the overall findings show that knowledge sharing brings common understanding among professionals, its application depends on resource of the health facility and professional‘s knowledge, skill and attitude (KSA), is facilitated by development of technology platform and automating the hospital system in general and it also need committed management body for its execution. Based on the study, appropriate sample content development and technology platform using word press software for knowledge sharing among professionals at MCH unit is designed. The findings highlight the ongoing educational, informational, infrastructural and other interventions to address the issue of knowledge sharing among professionals. In addition, appropriate recommendations are forwarded to the respected bodies.Item Information Support System for Maternal and Child Healthcare(Addis Ababa University, 2016-06) Kaba, Oli; Bekele, Rahel (PhD)Using information technology to reach mothers directly with health information customized to their stage of pregnancy.Mobile phones applications are able to quickly and easily disseminate information that will inform women of ways to care for themselves during pregnancy, dismiss tradition and misconceptions, highlight warning signs, connect women with local health services,reinforce breast feeding practices, explain the benefits of family planning, and make new mothers aware of how best to care for their babies. The aim of this project is to design information support system for maternal and childcare, to identify the current sources of maternal and child healthcare information and the need for a mobile based system, to design a prototype mobile application platform for providing maternal child healthcare information. A software development life cycle (SDLC) methodology of object-oriented approach applied to the study of the design system. Interview and document review were used as a main tool to capture the system requirement along with observation. Unified Modeling Language (UML)development techniques applied in the process of requirements capture, modeling, system analysis and design. SPSS and Visio Software were employed in analysis and design models diagramming. The results of this study show that an expectant women currently access maternal and child healthcare information from the media, brochure (or information sheet), Health extension workers (HEWs) and Health Development Army (HAD). The women in each development group are clustered in one of five networks. In developed countries, mobile phones are widely used to provide maternal and child healthcare information through mobile applications. Accessing maternal and child healthcare information directly to by expectant women and new mothers is an innovative way to empower women to take action to improve their own health and the health of their children and families. The researcher recommends the implementation of the design by Partnerships with health professionals , hospitals and healthcare NGO's to ensure the maternal and child healthcare information they provide, antenatal care clinic , health events and more can be informed the target population by means of mobile applications.Item Knowledge Management Maturity Assessment in Development Aid Organizations in Ethiopia(Addis Ababa University, 2013-05) Ayalew, Hermella; Bekele, Rahel (PhD)Effective delivery in the fields of development aid relies on knowledge and its communication and reach of dissemination. Development assistance organizations, practitioners and stakeholders are considered as key actors in the production and communication of knowledge. Knowledge exchange among practitioners in development assistance is now at the forefront of global development policy formulation. This is also true in Ethiopia where a multitude of development agencies interact, produce knowledge and share among themselves to meet their development assistance objectives in support of the country’s growth and transformation plan. To better understand the ongoing state of knowledge management (KM) in development aid organizations, this study adopts the perspective of Kruger and Synman (2003) to assess and describe the process in which knowledge management is defined, managed, controlled and implemented in knowledge-intensive Development Aid Organizations in Ethiopia. The survey assessed the level of knowledge sharing activities and suitable arrangements in place to facilitate the implementation of knowledge management initiatives in their respective organizations. Majority of the respondents indicated that their organization has strong knowledge sharing mechanisms even though not all mechanisms are yet systematic and well organized. Almost all respondents (90%) felt they have adequate ICT infrastructure in place that could support current or future KM initiatives. The majority of the organizations who participated in this study recognize the importance of managing knowledge and claim to be making serious attempts to establish active KM initiatives. Respondents felt varying degrees of current and future KM initiatives represent a significant opportunity to improve their current work performance. Responses to a question on key challenges impeding effective knowledge sharing fell in the realm of lack of time or resources, some staff members being reluctant to share knowledge, concern that sensitive/confidential information becoming public and most importantly lack of formal organizational guidelines on proper knowledge sharing and management. While the overall lack of well-defined KM strategies is a challenge, there are good practices and respondents have shared that their organizations are rapidly moving towards building on and further developing their knowledge management practices in the coming few years. Based on the responses gathered the study concludes by recommending action points that enhance conducive conditions for effective knowledge sharing in support of development goals. Further research is needed to evaluate the direct or indirect relation between the knowledge management practices already in use and the implementation effectiveness of development assistance objectives.Item Knowledge Management Practices of Commercial Banks in Ethiopia(Addis Ababa University, 2014-06) Reji, Habte; Bekele, Rahel (PhD)Knowledge Management benefits the Ethiopian banking industry for rendering quality services. In this dynamic world, the banks will not be able to compete in an open economy unless they have invested KMSs to get most of the value from the banks' assets. In this context, It is important to identify the KM practices found in the bank and implementation of KMS an appropriate tool to control business focus. This study attempts to investigate the knowledge management practices of commercial banks in Ethiopia. To this end, primary and secondary sources are consulted to get the necessary information for the research. Questionnaires are distributed to employees of IT and HR departments of the five randomly selected banks. In addition, a semi structured interview also held with appropriate department personnel. The result of the study revealed that currently, the banks do not have any formalized way of managing knowledge. But this doesn’t mean that there is no any means of managing knowledge totally within the banks. It is also found that the banks don’t have full-fledged computerized system for managing knowledge. Thus, employees don’t easily access the existing knowledge. The banks are expected to work on this area. Regular updating of lessons learned exists in all the banks considered. The study result also showed that most of the employees are willing to share their knowledge openly to other members of the bank. Based on the findings, accusation of tacit knowledge of employees exists within the banks but it is at the infant stage. Majority of the KM practices are not done in a centralized manner. Rather paper based communication is more used to transfer and share knowledge. It is also found out that there is no organizational unit dedicated for KM and also no position for knowledge worker in the organizational structure.
