  • Traffic Evaluation Model of the Opening Road in Residential area based on VISSIM simulation

    With the increasing urban road traffic pressure in closed residential areas, the problem of road patency in residential areas has become a hot topic. This paper established a traffic evaluation Model of the opening community based on VISSIM simulation. We constructed different types of residential areas, and compared the impact on traffic after opening different kinds of areas. With the analytic hierarchy process, we selected ten important indicators from three aspects. Then, the parameters of the road structure were put in the VISSIM simulation, and quantitatively analyze the impact of various types of residential areas opening. The results showed that changing the traffic rules at the intersection of the community has the greatest improvement in traffic capacity, reaching 89%. The influence of increasing the internal road and changing the external road structure of the city is more visible, reaching about 60%. The overall opening-up policy should be suitable for different localities.

  • A Comparative Analysis of Four Path Optimization Algorithms

    Path / route optimization for promptly moving equipment and personnel from base to disaster location has remained a nagging challenges for effective emergency response particularly within the context of developing countries. Bad road networks, poor and outdated navigation systems, faulty transportation vehicles, and traffic congestion remain among the top challenges militating against effective emergency response, and this has resulted in mounting statistics of losses for lives and properties within such jurisdictions. The pressing question has been: how can emergency response itinerary be planned and scheduled most optimally and reliably in the face of these challenges? This research paper compares four of the more popular path / route optimization algorithms (the Ant Colony Optimization Algorithm, Dijkstra’s Algorithm, Bellman Ford’s Algorithm, and Suurballe’s Algorithm), in order to determine the trade-offs and advantages that they present with respect to each other, and propose actionable recommendations for implementation. The findings of this research would prove useful for emergency response planning, particularly within the context of developing countries where these challenges are commonplace.

  • Enhanced Churn Prediction in the Telecommunication Industry

    Prediction models are usually built by applying a supervised learning algorithm to historical data. This involves the use of data analytics system that uses real-time integration and dynamic real time responses data to detect churn risks. Subscribe are increasingly terminating their membership agreement with telecommunication companies through mobile number portability (MNP) in order to subscribe to another competitor companies. To model the Customer prediction, a Markov Chain Model will be used. The Markov model allows for more flexibility than most other potential models, and can incorporate variables such as non-constant retention rate, which is not possible in the simpler models. The model allows looking at individual customer relationships as well as averages, and its probabilistic nature makes the uncertainty apprehensible. The Markov Decision Process is also appealing, but since dynamic decisions along the lifetime of the customer will not be evaluated the Markov Chain is the simplest model that still meets the requirements. Each state in the Markov Chain will represent a person being a customer for one month, with an infinite number of states. The transition probability to move from one state to the next is equivalent to a customer retaining with the operator to the next month. A customer that has churned will be considered lost forever. Once the retention and churn rates are determined, the reference churn value for each customer will be computed. The churn rate will be calculated using MATLAB Monte Carlo simulations, running a large number of fictitious customer-company relationship processes, and extracting the results of the average customer. Using simulation approach gives better result than analytical methods, since an indefinite number of states make matrix algebra complicated. It also allows visualizing the distribution of the results more easily than with algebraic calculation easily than with algebraic calculation. To the telecom companies the result…

  • Independent operation Advantage integration Complementary development—An analysis of the relationship between newspapers and websites

    The rise of online media has left paper media, especially newspapers, in a very awkward position and there is still a debate on the relationship between newspapers and websites, many people in the industry called the two a relationship of “newspapers and the Internet is father and son”, which is a false understanding. This paper holds that in the case of newspapers and networks belonging to the same newspaper office, the two should operate independently, integrate their respective advantages, complement each other, inter-develope, so as to implement a win-win situation for newspapers and websites.

  • The Role of Community on Forest Management in Ethiopia: The case of Yotyet/Yewezera Community Forest

    This independent study assessed how forest management is a matter of local community governance and management by showing best cultural management practices in Ethiopia with special reference to Yotyet/Yewezera Community forest which is located in Eza Wereda, Gurage Zone, Ethiopia. Forests are essential for human survival and well-being. They harbor two thirds of all terrestrial animal and plant species. They provide us with food, oxygen, shelter, recreation, and spiritual sustenance, and they are the source for over 5,000 commercially-traded products, ranging from pharmaceuticals to timber and clothing. Due to lack of evidence in Ethiopia and more broadly in Africa, Community Based Forest Management approaches have been underestimated. The study area, Yotyet/Yewezera natural forest has four adjacent villages with 3421 population number. These four villages were purposefully selected. In-depth semi-structured interviews, focus group discussions (FGDs), direct field observations and questionnaires were the main sources of the primary data in this research. In all the four villages eight community elders whose age are above 70 years were selected purposefully. After giving enough awareness about the research objective and they were interviewed separately and finally they involved in to Focus Group Discussion. Qualitative historical analysis is employed to understand and interpret the forest governance and management. Three time periods were considered. The forests’ protection status was assessed during the feudal period (before 1974), during the Derg regime (1974–1991) and after 1991. The three time periods were characterized by major changes that affected the management role of the local community. From the beginning the forest was protected/governed/managed by representatives of the surrounding community which were known as local chiefs. These local chiefs were well respected by the community and their order towards forest management issue had been accepted and practiced accordingly. Apart from local chiefs there was also one strong traditional belief that was…

  • Role of Women in Tulama Oromo Gada System: The Case of Ilu, South-West Shewa Zone, Oromia Regional State

    This study deals with the role of women in Gada system in Tulama Oromo of Ilu. Gada is an indigenous institution that incorporates political, social and economic issues of the Oromo. In this institution, Women have their own role and status in the political, social and economic affairs of the Oromo society. The objective of this study is to examine the role of women among Tulama Oromo of Ilu Gada system. To achieve this objective, both primary and secondary data was used. Accordingly, interview, focus group discussion and participant observation were employed to collect data. For this purpose, informants were selected from Abba Gada (father of Gada), Luba, Jaartii Cifree (wife of Yuba (retired Gada elder)), Haadha Siiqqee (wife of Abba Gada, Luba), community elders and culture and tourism office from government officials. These informants were participated in interview, focus group discussion. In such way, 36 informants were directly involved in the study. In anthropological studies, analysis is an instrument to extract meanings and interpretation from the data obtained during fieldwork. In such manner, data were presented in a qualitative type. The findings of the study show that women have tremendous role in gada system. In this case, no event or no ceremonies take place without the full participation of women. Women were basically represented and/or play a significant role through different institutions such as Siiqqee and other ritual ceremonies and institutions working as check and balances for protecting women’s right in general. Hence, without participation of women, the Oromoo socio-political practices could be meaningless. That is to say, any social, political and economic practice irrespective of women may not be fruitful. Based on the research findings, some recommendations were forwarded that strengthen understanding of Gada system.

  • Perspective Of Integrated Transport Systems For Sustainable Development In An Emerging Economy

    Transport system plays a vital role in the economic growth and social wellbeing of any nation. In spite of its investment, Nigerian transport system has not always shown competent for accomplishing sustainable development. This paper examined the correlate of integrated transport and sustainable development. This paper adopts both primary data and secondary data using questionnaires and statistical bulletin as instruments. Both Descriptive and Inferential statistics were used to analyse the collected data. The result showed strong correlation between integrated transport system and sustainable development. It was concluded that integrated transport system is a veritable tool for sustainable development in any developing nation. Integrated transport also boosts the GDP of any developing nation like Nigeria by harnessing the various modes of transport. Revenue earned from transport sector should also be used to finance the sector in order to boost the GDP of the sector and also enhance productivity and sustainability of the sector.

  • The influence of the media in the construction of food habits in children

    Introduction: Since the media is one of the main instruments of communication today, having a strong capacity to influence the construction of eating habits, especially in the children’s audience, we find pertinence in the association of these factors associated to the family nucleus. With regard to the family context, it is seen that children become more vulnerable to this technology because they spend a large part of their day surrounded by various instruments that, in most cases, allow negative access when it comes to conceptions food products, which is a consequence of the constant association of food advertisements with low nutritional content. With regard to the family context, it is seen that children become more vulnerable to this technology because they spend a large part of their day surrounded by various instruments that, in most cases, allow negative access when it comes to unhealthy conceptions food products, which is a consequence of the constant association of food advertisements with low nutritional content. Objective: Therefore, this work aims to correlate the influence of the media in the construction of eating habits in children. Methodology: This is a review study of the literature, with papers in Portuguese, researched in the period from 2011 to 2017 referenced in the Google Scholar database, having the following expressions as descriptors: Influence of Media and Eating Habits. Results and Discussion: We noticed that most publications we found claims that the media has a strong relationship in the construction of children’s eating habits since they are more susceptible to influence and manipulation, because they do not have a critical sense formed yet. Another relevant aspect is the interference of food in the family nucleus, which generates resistance to the adhesion of new healthy eating habits. Thus, we consider the importance of discussions involving media power in the…

  • To establish protocols of multiprofessional team for oncology service in the Hospital das Clínicas of Pernambuco

    Introduction: Multiprofessional team is the joining of efforts and interests of professionals who recognize the interdependence with other components in a cooperative work, to achieve synchronized and coordinated activity. Objectives: To establish protocols for patient care through discussion and construction of a plan of care for each patient admitted to the ward of the Oncology Service of the Hospital das Clínicas of Pernambuco (HC-PE); Promote security for the professional performance and integration between them; Stimulate the updating and constant training of the Multiprofessional Team. Methodology: Within 72 hours of hospitalization, we constructed the care guidelines for patients, in addition to preparing them for care after hospital discharge. The components of this team are social worker, doctor, nurse, speech therapist, nutritionist, psychologist, occupational therapist and pharmacist. Meetings are held on Tuesdays, Thursdays and Fridays at 10:30 am in the ward on the eleventh floor of the HC-PE. The instruments of work are forms where we record the goals of care for the current hospitalization of each patient, planning after the discharge and another where the meetings with relatives and the respective referrals are registered. Communication and dissemination takes place through an email group and drive for document sharing. Every week, each member of staff presents aspects of their area of expertise.

Conclusion: The performance of this group in the oncology ward has ensured an integral care for the patients and unifying the working language of all the team, besides bringing more safety to…

  • Humanized Care to the Elderly with alzheimer: Nanda Nursing Diagnosis

    Introduction: Alzheimer’s disease is characterized by multiple cognitive decline involving memory impairment and progressive loss of functional capacity, where the client needs multidisciplinary care. Objective: to evaluate the actions of caring for the elderly with Alzheimer’s disease from the perspective of the nurse. Methodology: Integrative review, where 7 articles published in the last five years that composed the study sample were identified from the Lilacs, SciELO, PubMed, Medline and Bdenf databases. Results and Discussions: The main nursing diagnoses found by Nanda patients experienced by Alzheimer patients were: chronic confusion, risk of injury, impaired communication, activity intolerance, self – care deficit, impaired social interaction and interrupted family processes. However, in one of the studies on nursing diagnoses, it was possible to identify improvement of the cognition of the patient with (DA) through the application of the Mini Mental State Examination (MMSE), which is a cognitive evaluation scale that exercises immediate memory, incidental and late. In other studies, poor knowledge was observed, assisting the recognition of learning figures and early identification of depression, aiding in the pattern of impaired sleep, the risk of loneliness and chronic sadness. The nurse, through his theoretical and technical resources, should provide means to facilitate care, among them, establish communication strategies between him and the patient, in order to delay the evolution of the disease. Conclusion: Study showed the importance of implementing the nursing process for this focus, which allows comprehensive care to the Alzheimer’s patient
