    Nowadays, the Internet is developing rapidly, while in the context of the mobile Internet Making photos to make money, a kind of self-service service mode currently has the problem of unreasonable task pricing, which leads to the failure of commodity inspection. Hence, in order to solve the problem, on the basis of a set of completed project task data and the whole registered member information provided by the company, we set up Multiple regression model and Bayesian equilibrium model by means of the mechanism analysis to determine models, big data statistical to determine parameters and considering the various factors that can affect the price of task. Not only can the models established in this paper greatly optimize the task pricing scheme, but also them do improve the task completion degree as much as possible and play a positive role in the efficiency of program operation under the premise that the total cost is basically unchanged.

  • Causes Affecting Parental Involvement In The Schooling Of Children

    Parental involvement (PI) in the education of children is not a recent phenomenon. PI has become an established feature of education policies across the developed world. The study set to establish factors that may make parents choose not to participate in education process or unable to become more involved. The study was grounded in Epstein’s overlapping spheres of influence theory. A qualitative case study was employed. Purposive sampling was used to select (4) schools and (40) participants in Alefa district, Central Gondar Zone, Ethiopia. Findings revealed that the economic status and level of education of parents have a significant effect on children’s education. It also emerged that parents are more likely to be involved when teachers’ perceptions about role of parents are positive. The study established that PI is also influenced by age of children. The study recommends that parents be helped to appreciate the benefits of parental involvement in the learning of their children. Workshops should be established to develop the relationship between parents and their children.

  • Optimizing the Site Selection of Payment Stations Based on P-median Mathematical Model

    Site selection is one of the classic problems in operations research. In this research, starting from a mathematical modeling example, a model was established to solve the site selection problem of 6 toll points in 52 cells. Taking the shortest distance between the residential area and the toll station as the objective function, this paper introduced 0-1 variables, established the P-median site selection model, and transformed the residents’ payment query problem into a linear programming problem. The Lingo software was used to solve the problem of positioning the 6 points as 1, 6, 14, 26, 28 and 36. This paper successfully applies the site selection model to the site selection of toll station, which has certain reference value to the site selection in real life

    In order to investigate the effect of temperature of absorption liquid and exhaust temperature of diesel engine on decarbonization efficiency of marine decarbonization tower, the effect of temperature on carbon dioxide absorption efficiency in ship exhaust was studied by means of theory, experiment and simulation. Because of the particularity of the experiment, three exhaust temperatures of 25, 45 and 65 degrees celsius are mainly set up in this paper. The relevant experimental data are collected and analyzed under idle speed, 25% load condition, 50% load condition and 75% load condition, respectively. The experimental results show that under the same load, when the exhaust gas temperature increases, the absorption efficiency shows a downward trend. and the experimental exhaust gas temperature was simulated by Aspen plus software from 35 to 200 degrees celsius respectively. the simulation results show that the absorptivity decreases with the increase of temperature, and the simulation results are consistent with the experimental results, which has a certain reference for the design and operation parameters selection of marine decarburization tower.

  • Assessing The Teaching-Learning Roles Of Instructional Leadership In Some Selected Primaey Schools

    The purpose of this study was to investigate teaching –learning roles of instructional leadership in the full cycle primary schools of Chilga woreda, Central Gondar Zone. To meet the objectives of the sudy descriptive survey design was employed. Teachers, principals, supervisors, and woreda education officers were used as primary sources of data, and annual reports and different document records used as secondary sources of data. Regarding to sampling, teachers were selected by lottery method, and principals, supervisors and woreda education officers were selected by purposive sampling method. Questionnaires, interview and document analysis were used as data collection instruments and the data were analyzed through mean, standard deviation and compare means. The finding of this study revealed that almost all instructional leaders were subject specialists, lacks skill and training, and lacks commitment and moral to accomplish their tasks and severe shortage of finance. Based on the findings, it was concluded that: Schools were to some extent incapable of enhancing teachers’ professional skill development and improving the quality of education. The stated vision and defined mission in the school did not command the ownership of its potential stakeholders since it was not supported by its potential stakeholders. Instructional leaders did not possess the required skill, knowledge and attitude through training. In line with the above findings and conclusions it was recommended that: to equip instructional leaderships with necessary knowledge, attitude and skills the Region, Zone and Woreda Education Officials may arrange workshops, seminars, short and long term training in collaboration with different universities, colleges and NGO’s and schools need to think of their own income generating sources on top of government budget through improving their relationship with local NGO’s and school communities by preparing project proposal and submit to international donors.

  • Advantages and Disadvantages of Neoliberalism/Neoliberal Economic policy in General and the case of Ethiopia in Particular

    Introduction: The same dictionary describes Neoliberalism also, which is said to be “a modified or revived form of traditional liberalism, [especially] one based on belief in free market capitalism and the rights of the individual” (Oxford English Dictionary 1989a). Currently because of the age of globalization, the world is becoming to be conceived as a village. One of the major projects of globalization is the integration of the political economy of the less developed regions in to the global political economic order. Accordingly, during the past few decades the continent of Africa has been trying to integrate itself in to the international political economy either forcefully or by consent. Generally, it is obvious that the main theme of neoliberalist is a fundamentalist view of “leaving everything for the market and the private investors with no interference of the government on the economy except keeping law and order. Historical Background of Neoliberalism: Now a day, world is integrated and became a village. The driving force of this integration is the ideology of Neoliberalism. Under this integration states are recommended or forced to open up their markets to foreign companies competitions, to minimize the role of the government in the economy including minimizing the government expense for social security and social goods, to create fertile grounds for the market to be the only means to distribute the wealth of a nation and the prices of goods and services to be determined based on the principles of demand and supply (Tewdros, 2011: iii). According to Saad-Filho and Johnston (2005:1), “we live in the age of neoliberalism”. The policy of “neoliberalism can be traced to the late 1960‟s and early 1970s as a particular strategic response to the crisis of Keynesianism” (Fassil, 2008:506). It was started in 1960s by a group of professors from…

  • Productivity and Grain quality of Holker, Ibon and Franka malt barley (hordeum vulgare l.) varieties to the rate of nitrogen fertilizer

    A field experiment were conducted during the 2018 cropping season at central highlands of Ethiopia to determine grain quality and yield response of malt barley (Hordeum vulgare L.) varieties to different rate of nitrogen fertilizer. The experiment was laid in a split plot design; Nitrogen rate as main plot and varieties as subplot with three replications. Phonological traits, Grain quality parameters and yield were taken as experimental variables and analyzed using SAS software. The result showed that grain yield, thousand kernel weight and hectoliter weight were significantly affected by interaction of Nitrogen and varieties. However, days to heading, days to maturity, plant height, number of productive tillers, straw yield and number of grain per spike were significantly affected by both N and varieties. On the other hand days to emergence, spike length and harvest index was not significantly affected by N and varieties. The higher (2.705 t ha-1) grain yield was recorded from the combination of Ibon variety with 57.5 kg N ha-1. Therefore, application of 57.5 kg N ha-1 fertilizer rates and Holker variety and 57.5 kg N ha-1 and Ibon variety were found to be better in terms of agronomic for malt barley production at central highland of Arsi, Ethiopia.

  • The Pharmacists in Ambulatory/Outpatient Care

    Ambulatory care pharmacy practice is defined as the provision of integrated, accessible healthcare services by pharmacists who are accountable for addressing medication needs, developing sustained partnerships with patients, and practicing in the context of family and community. This is accomplished through direct patient care and medication management for ambulatory patients, long-term relationships, coordination of care, patient advocacy, wellness and health promotion, triage and referral, and patient education and self-management. The ambulatory care pharmacists may work in both an institutional and community-based clinic involved in direct care of a diverse patient population. A variety of specialty clinics are available for allergy and immunology, pulmonology, endocrinology, cardiology, nephrology, neurology, behavioral health, and infectious disease. Such services for this population may exist as a primary care clinic or an independent specialty clinic, typically in a PCMH, which is instrumental in coordinating care between various providers. Once a practice site is identified, it is important to establish a strong, trusting, and mutually beneficial relationship with the various decision-makers (e.g., administrators, providers) involved with the clinic. If pharmacy services are currently in existence, the pharmacy director may be able to identify and initially contact the appropriate person. If another pharmacist is providing clinical services, this person would be a resource to help determine areas for expansion of patient care and to whom to direct the proposed business plan. Additional individuals to consider as an initial point of contact include the clinic manager, clinic medical director, or administrative assistant to either of these persons. If the clinic setting is affiliated with a medical school, it may be necessary to contact the Department of Family Medicine head.

The use of constant temperature town empty warehouse not only ensures the quality and safety of fans, but also maintains the precision of each weighing quality. Finally, the robotic claws of the robot arm are used to control the rotation of the robot by multiple bionic control.

  • Head And Neck Tumors: Oral Repercussions Of Antineoplastic Therapy

    Introduction: Head and neck neoplasia is the sixth most common cancer in the world and can manifest in several areas of the head (mouth), scalp, skin of the face and neck. The treatment of choice is defined according to the histopathological type, topographic location, relation with neighboring anatomical structures, staging, general clinical condition of the individual affected by the disease and medical-hospital conditions, ranging from surgery, radiotherapy and uni or multimodal chemotherapy. Despite the various therapeutic possibilities for head and neck cancer, all treatments bring with them side effects, immediate and / or late repercussions that may compromise the function and buco-maxillofacial aesthetics and, consequently, the individual’s quality of life. Objectives: To identify side effects and immediate and late oral repercussions arising from antineoplastic therapy in the head and neck region. Methodology: Literature review based on published articles available on the internet, in the database systems: Medlars on line International Literature (Medline), Latin American and Caribbean Literature in Health Sciences (Lilacs) and Brazilian Bibliography of Dentistry (BBO) present on the website of the Virtual Health Library (VHL). Results and Discussion: The literature is unanimous in indicating the most frequently observed complications in this group of patients: mucositis, opportunistic infections, radiodermatitis, hyposalivation, xerostomia, radiation caries, dysphagia, ageusia, trismus, soft tissue necrosis and osteoradionecrosis. In addition to the morbidity associated with cancer, its treatment also produces numerous side effects, several of which are oral manifestations with immediate and / or late repercussions, and may present more markedly in patients with precarious oral health conditions and lack of dental care. Conclusion: It is imperative to seek the prevention and early diagnosis of these tumors, in order to avoid death and mutilation, which compromise the patient’s quality of life, as well as provide timely dental care.
