What Is The Role Of Engineers?
What Is The Role Of Engineers?Through the determination hardly a(prenominal) decades the physical step-up of population has become unmatchable of the worlds highest surroundingsal threats. This growth has created remarkable demands for land, transportation, push button, irrigate, sanitization, etc., and tag the different beas or fields where engineers ar working. As a outcome, todays engineers in both raiseed and growth countries moldiness to adopt a smart holistic hail toward inseparable and companionable systems (Amadei 2004). Which means switch the lordly nature approach for cooperating nature approach through sustainable increment in practice. Engineers, community that design professional issues for sociable issues, atomic number 18 compete a vital role in the construction of modern societies, although the slipway as they overcome and approach these depend large(p)ly on the socioeconomic conditions which vary signifi low livelinesstly. This essay de refe rence discuss the role of engineers in under fractureed nations and analyse water supply sanitization and cleverness as cardinal of the most signifi ceaset argonas touch on by their decision-making.Role of engine roomgeneral PerspectiveThe role of engineering science has suffered many changes over the last few decades, although its concept which is ground on trial and error has re of imported an essential member of the scientific-technological method where mixer, environmental and gentleman factors define the most suitable solution to grip a particular issue. Thus, engineers role is continuing reshaped according to the repenny ch wholeenges and necessities implicated by specialized disciplines on particular beas of technology (civil, chemical, agricultural, etc.). (UNESCO 2010, p. 24) coeval Perspective and sustainable ontogenyUnlike the 20th century where the engineering era seemed to take a crap unlimited intrinsic sources, todays century is facing solid problems that are putting enormous hug on the environment (Azapagic, Perdan Clift 2004, pp. 3-5). Therefore, todays engineers in like manner the rudimentary technical and scientific companionship of the engineering discipline, they likewise encounter to contribute and enhance sustainable disciplineing that meets todays necessities with aside affecting adversely the capacitance of upcoming generations to meet up their own necessitates. This sensitive role of engineering, demands clean practices based on social-environmental factors quite than skilful business intentions.Impact of engineering on societyThe taradiddle shows numerous examples in which engineers performance has widely influenced among communities. Quality of life, economic wealth and good infrastructure for instance, are iodin of the most relevant and common indicators of their weight on society. As (UNESCO 2010, p. 40) subscribe to stated, by 2025, the worlds population will have incrementd from 1.5 jillio n to 6.6 billion approximately and the percentage of migration to urban areas will rise from 40 per cent to 60 per cent. This in constitution shows that urbanization rates will boost dramatic whollyy. subsequently engineers have the duty to denounce impressive and sustainable solutions as an coordinated approach without generate forbid impacts, which is known as engineering social responsibility.Ethical side of engineeringIn general terms, engineerings ethics is without delay related with engineering responsibilities regulated by measuring rods codes which act according to several(prenominal) short letters. The objective of the ethical factor in engineering rather than just fixed up rules, is drawing solutions with reflexion of particular situations fixed into preliminary principles. On this basis, at the era of making decisions, engineers should take into account the interest points sustainable companionship, protection of the public-environment, faithful agent of stak eholders related with objectivity, competence-knowledge, fairness and justice, virtue in the workplace (dedication and service), and professional accountability- leadership. (UNESCO 2010, p. 190)Engineers in Developing CountriesAs in wined nations, engineers moldiness work within the social, economic and environmental circumstance in order to guarantee sincere sustainable development for the undivided world (Parsons 1996, p. 170). Social responsibilities such(prenominal)(prenominal) as water supply, sanitation, food, life force and environmental protection are the afore give tongue to(prenominal) in developing countries. The difference resides on the socio-economic factors which are directly influenced by peoples behaviour, governments positions and development priorities.Engineering skills and ethics in Developing nationsAs is described in the section A.1 and A.3, competences and principles of engineers in developing countries re main(prenominal) the resembling as standar dized characteristics. The great ch in entirelyenge for them is in fact, to develop realistic projects on quantify to particular communities and technology purchasable (Parsons 1996, p. 170). In fact, environmental issues, often take less importance because in that location are separates which have roughly(prenominal) relevant social impact, oil explorations for instance. victorious and failed projectsThe winnerful and failed projects in developing countries depends much on the capability of engineers to compress projects with a clear understanding of the objectives, reliable opinion of resources availability, business, and technical requirements and effective communication among stakeholders. The ability to implement accurately these facts will bring up useful and applicable alternatives to address real issues. By contrast, lack of tutelage to the social-economic context, ethics codes, unrealistic expectations, underestimated time, whole tone and cost will bring haples s outcomes. (Parsons 1996, pp. 171,172)Relationship amidst technology and socioeconomic factorThe use of high-technology does non guarantee a successful project or accurate solutions. In order to achieve good results, engineers essential be able to make a balance between use of technology and socioeconomic attributes. Parsons (1996) points out that the appropriated selection of technology will determine not only projects success also its viability. As a result, there are four points to charter appropriated technology according to socioeconomic factors it moldiness be conceptual and physic solelyy compatible with operators, spare parts and equipment must be available in the influenced area, project funding must be commensurate with its budget, and the technology must be compatible with the physical environment where it will be used. This lesson leads to concluded that the relationship between technology and socieconomic factor is very narrow, it must fit users and inescapably as salubrious as must be designed to ameliorate quality life.Engineering AreasEnvironmental crooks that are cause advanced engineersBrief mention of meaning(a) events that encourage environmental purview on engineeringWorld population, fol outseted by climate change are considered the two main factors that are shaping new engineers with environmental approach. During the last half of the 21th century world population increased from 2.5 billion to 6 billion especially in less economically developed countries, this trend is expected to peak at 9.3 billion by 2050 (United Nations 2012). In addition, overpopulation also has been linked with higher demands of natural resources (water, cro inventiond, forest), shanty settlements, transportation-infrastructure deficits etc. Another valuable event that is making an environmental approach is the fact that the current world(prenominal) economic is based on produceivity, which has brought several impacts associated with greenhouse ga ses, waste product of fossil fuels and air pollution. Climate change is certainly the result of all these elements at an abnormal rate. Thus, the world has changed its development approach to sustainable development (Brown, Rener Halweil 2000). Hence, most of professional corporations have incorporated sustainable development into their invention statements and codes.New model of larn and practiceTo await the global challenges that the human beings are facing today, engineering education has incorporated the concept of sustainability into all engineering fields. This means, that professional are expected to make reliable decisions that improve quality of life as well as reducing negative impacts on environment and levels of consumption, and planning their actions according to socio-economic factors and technology available. Consequently, the wait on of learning and practice has been adjusted by a model of education more than realistic-practical. Where students throughout work shops are learning and building knowledge in real situations, as well as has created in them greater environmental responsibility. (Amadei 2004).Sustainability and switchingAs explain Azapagic, Perdan Clift (2004), there are certainly three constrains that create the concept of sustainability. Techno-centric concerns, which re subject human expertise, ingenuity and economic systems, Eco-centric concerns related with natural resources and ecological capability and socio-centric concern based on human and social expectations. The Techno-centric concerns, has been traditionally used in the crop of education in engineering, the responsibility of todays engineers is to include in equal proportion or balance all three constraints to achieve a sustainable development. Which ultimately is seeking for human wellbeing, in other watchwords satisfying human needs, improving quality of life in an eco-friendly way.Water Supply and SanitationDeveloping Nations scopeUNESCO (2010) states that water supply is one of the most serious problems facing by developing nations, in India for instance, 85% of the urban population has access to swallow water, but only 20% of the of this meets the wellness-quality standards set by World health Organization. Additionally, the workaday rate of water supply often is very low and depends on economic factors and location. The situation on sanitation is even worsened often sanitation has lower priority than water supply. It has estimated that 2.6 billion people do not have properly or existing sanitation system in developing countries. Another issue related with sanitation is in fact that sewer water and solid waste collection run and stormwater drainage are inadequate. Littering directly to open areas for instance, has created environmental impacts on come along and ground water resources being more dramatic in areas such as shanty towns.Engineering Challenges Engineers approachThe traditionally treatment of water supply and sanita tion focussing is considered now as a standard procedure. Which has several treatments according to the water physicochemical characteristics, technology available and environmental regulations. Although, it is by no means certain that this procedure has been the best. Indeed, 95% of the wastewater in the world has been discharged to the environment without treatment (Montgomery Elimelech 2007). Hence, Beside new regulations and codes, todays engineers rather that replicate solutions from developed countries to developing countries, they will have to meet basic needs of all communities for water and sanitation and work as facilitators of sustainability approach within context institutional, social, political, economic, environmental and technological. Thereby, the issue of water and sanitation in developing countries will be overcame or at least rock-bottom. For example, antiseptic production can be an expensive solution, however it is really depends on numerous conditions linke d with the population objet, such as natural resources, requirements and social class.EnergyDeveloping Nations backgroundIn the next few decades, the pressure on zip services will increase considerably in developing nations. It is predicted that energy consumption worldwide will increase well-nigh 30% from 2007 to 2030 and most of that growth will be came from developing nations. As a result, the intergovernmental panel climate change (2007) point out that these energy issues will be addressed through cost-effective energy programs based on the reduction of fossil fuel use implementations of ecofriendly technologies and renewable energy in housing, transportation and industrial sectors and finally the reduction of life-cycle cost, this related with all expenses in the design, construction, operation and maintenance of a particular project. (Liu, Meyer Hogan 2010, pp. 35,36). Todays modern development demands serious energetic programs that fix up both economic development and sust ainable development based on the rational use of natural resources.Engineering Challenges and approach in developing Nations.Worldwide experiences have showed that the electric switch of non-renewable to renewable energy seems to be more expensive and moreover, didactics to the highest degree renewable technologies is inadequate or unreachable. For that reason, the common commitment for engineers on energy solutions is declare oneself break dance alternatives in terms of sustainability and development. Adoption and design of new technologies, regulations, engineering supervision within national strategies, continues updating, earmark advice of energy requirements, etc., will be the common areas where engineers role will be decisive for environmental energy development in the less economically developed nations. (UNESCO 2010, p. 288).Levines preservation Model Theory Case StudyLevines Conservation Model Theory Case Study tally to Rafieian-Kopaei, Setorisi, Doudi, Baradaran, Nasri (2014) atherosclerosis is a result of hyperlipidemia and oxidation, and it has been a principal factor of mortality in developed countries. Atherosclerosis is a common malady where fatty deposits called atheromatuos plaques develop in the inner layers of arteries. This attend to begins with a deposition of small cholesterol crystals in the intima, so the plaque grows, and inflammation suffice develops in the same time, which results in the fibrous tissues development. As a result this process, clot formation and thrombosis are developed, which conclude in blood obstruction and consequently in heart deficit and other factors dependent of the place where it is affected. In the same cases, Strain, Hughes, Mayet, Wright, Kooner, Chaturvedi, Shore (2013) had described that virtually consequences related to atherosclerosis such as hypertension and ischemic heart disease, so these are two main disease, which can be developed in the process of atherosclerosis. Besides, Levine (1973) in her circumspection for surmise has introduced the theory of saving model where holism is a get wind factor in the process to cautiousness and palm a thickening. end-to-end the course of this paper, I will describe a customers narrative, a concise introduction about the Conservation Model theory, the cover of this nursing theory for the client, and a response plan with a inveterate fretting model, which can be applied for this client.Firstly, the clients history is essential to know and understand, so the caregiver and health professional can develop methods, which facilitate the life this mortal. The uncomplaining V.D has described part of his history in the following information. Mr. D., 47 years old, married, has not concluded wide-eyed school, is atheist, and is a farmer. In his family history, he described that his parents had died because of heart complications, but he did not know the exact cause. Mr. D. had been submitted to stent implantation where exams had proved the diagnoses of coronary artery disease. After six months, he was submitted to bypass surgery. Even though a focus hemorrhagic had developed, Mr. D. was resubmitted to another interpolation surgery, in the same day, to hear this hemorrhagic area.Also, before the discharge, Mr. D. has aimd simple explanations about how to proceed in the recovery time these explanations were about medication ( belief correct administration time and dose), caring about the dressing in the working(a) site, and orientation to give in to visit the physician in 60 days to have a r military rank about the general recovery and surgical site. The general knowledge to have adaptation was admitd by Mr. D.s family and friends, whom tried to suffer relegate quality of life in this crucial moment of recovery and adaption for a new life expression.In addition, some key chronicity concepts can be understood in the clients history. Related to Kramer-Kile, Osuji, Larsen, Lubkin, (2014) t hese chronicity concepts are 1- disorder experience, Mr. D. was diagnosed with atherosclerosis a short period before to be submitted to surgery, so he had develop d method to adapt to symptoms of this disease when he was developing his daily activities 2- stigma, it is related to the cultural background and level of education, so Mr. D. has limitation in his level of education so that it can promote an increase in the level of stigma 3- adaptation and quality of life, during and by and byward recovery, it promotes a drastic process to adapt in this new style of life because Mr. D. has experienced a new process (illness) in his life and his job (farmer) must be substituted, so he could have a adequate adaptation and quality of life 4- sexuality, Mr. D has a cardiac disease and did a bypass surgery, so it must have affected his sexual activity and, 5- self-care, as a farmer and has cardiac disease, Mr. D. must control his activities to provide better care and management for his li fe because the antagonist side it develops worse affects. In fact, chronic concepts are present in all process of the illness, so it needs to adequate for the person.Likewise, nursing theories are used to promote better care and the same time knowledge about the general process to manage the quality of life. As a result, the theory Conservation Model by Myra Levine describes the conservation model, which was originally a framework to teach undergraduate nursing student (Levine, 1973). The three major(ip) concepts for the conservation model are set-back, conservation, which is maintaining together of the life system (balance between nursing interpolations and client participation). Second, adaptation, which means an ongoing process of change, but the various(prenominal) economizes his/her integrity within realities of his/her environment. Third, one is existent when fundamental interactions or constant adaptations to the environment permit assurance of integrity (Alligood, 2 010). This theory has conservational principles as energy conservation, structural integrity, personal integrity, and social integrity (Levine, 1973).Still, in this theory, the metaparadigm concepts are the person, environment, health, and nursing. People are holistic beings who are sensitive, thinking, future-oriented, and cognizant. though, people are in constant interaction with the environment, responding to change in an orderly, sequential pattern, adapting to forces that form and reform their essence. In fact, the goal of client care is cash advance of adaptation and well-being (Alligood, 2010). These factors are reinforced by Levine (1973) that the process of client understanding his/her plan of care and diagnosing is vital. This theory reinforces the importance of the toy with holistic view during the nursing process to make a plan for the client.Then, the Conservation Model Theory is applicable for Mr. D. in his process of disease and illness, so a nursing theory is app lied to promote better process of care and quality of life. According to Alligood (2010) the Levines Conservation Model is applied in three main areas such as conservation, adaptation, and wholeness. In the aspect referent to conservation describes the conservation of energy, so Mr.D. must have restriction in his life to keep adequate levels of energy although he continues doing daily activities. For example, he is a farmer, so he needs to understand that some activities in the kingdom he cannot do because it will require high levels of activities. If he stops doing activities, he has a possibility to develop other factors, which decrease his quality of life. Also, farming requires different activities with lot of energy, but it is not a factor to set aside these activities. A management in the process to work can be favorable, and working in small processes results in the job concluded and the consistence in action.In addition, the adaptation is a rouge aspect present after the surgery, so it requires time and motivation from the client. In this process client, family, first caregiver, and health professional are involved in this process of adjustment. Though nurtures have a crucial function for the client, which is program line and doing management to provide better quality of life. Kramer-Kile et al (2014) emphasise the psychological and social result of chronic diseases require significant adaptations from the client. Consequently, Mr. D. has significant changes in his life such as alimentation, medication regimen, and daily activities (working).Through alimentation is not considered an important factor for some society, it has a key for the prevention and promotion of atherosclerosis. The frothing diet where has food with high quantity of saturated and fats, cholesterol levels, atomic number 11 and sugar can increase development of atherosclerosis. The unhealthy blood cholesterol and lipoproteins levels promote an increase in the atheroma, so the p rocess of occlusion of lumen is increased triglycerides is other factor to increase the occurrence of atherosclerosis. Also, overweight or obesity contributes super in this process because the level of exercises is totally reduced and weight gain is increased. Rafieian-Kopaei et al (2014) Mr.D. must need an adaptation in the alimentation where alimentary factors can be controlled and managed to develop a health alimentation.Moreover, the medication regimen and daily activities develop a reorganization in the routine. In the medication regimen a different types of medications are necessity to be taken, so a correct management of drug is un countermandable, so drug interaction will not result. Side effects can occur, so as a nurse must teaching the client about this process and emphasize for the client continuing the medication although he has this process. Even though medication regimen is prescribed by the doctor, nurse needs to contain if the patient understood and/or is takin g correct. Furthermore, daily activities must be reformulated because Mr. D. cannot continue doing high levels of effort. Hence, client, family, and health professional must work together to develop an adequate management, which provides comfortably and comfortable adaptation.Still, wholeness is a part of all these processes because the client and environment interactions to provide changes occurs in the same time that adaptation and conservation. The process of interaction with the environment is crucial whenever the human being interact with the environment and contrariwise, so both sides receive affects to increase or decrease life. As a result, conservation of energy and adaptation work in the same time with wholeness, and the quality of interaction must be satisfactory for client.In the nursing process taskment the nurse and client will analyze challenges in the clients environment and methods to be adequate in this system. Some aspects are necessary to observe in this proc ess such as energy conservation (balance between energy supply and demand), structural integrity (the system defense team of the body), personal integrity (clients dignity and personhood), and social integrity (clients involvement in the society or his community) (Alligood, 2010). Instead, in this process of assessment, the word holism is a fundamental definition in the general process to assess the client. As a result, looking for a short-long future some challenges can be observed, so it has great opportunity to change and develop other managements (Levine, 1973). Another example in the Mr. D. progress of illness is that his disease can be linked by genetic factor because as a described his parents had cardiac problems. Thus, his offspring has an increase possibility to develop cardiac problems in the life progress although it can be controlled by intervention such as educational factors, alimentation, exercises, and level of stress.Shalhoub, Sikkel, Davies, Vorkas, Want, Davies (2014) reinforce in a research about biologic factors of atherosclerosis that a person who has someone in the family (first lineage) has a genetic risk factors for susceptibility to develop atherosclerosis. Although a variant in the genetic and environmental factors can be present, genetic is an important factor-development to be considered. Likewise, Mr. D. needs to have orientation for other cardiac diseases, which develop in response of a first disease. In this progress, hypertension is a factor to be considered, so prevention and promotion are the basis in this progress. An adequate quantity of sodium by day is necessary, so teaching and explanation about it needs to be through (Rafieian-Kopaei et al, 2014). Consequently, a holistic view is necessary to understand the progress of disease and illness, so management in prevention and promotion are developed in conjunct with health professional and client.Another process in the theory is hypotheses, more specific goals, the nurse s eeks validation with the patient about his/her problem, so the nurse hypothesizes about the problem and its solution, which means the plan of care for the patient (Alligood, 2010). In order that, Mr. D. has some hypotheses for his situation such as risk for infection, deficit of knowledge in his process of care (post-surgical), inadequate cardiac output, acute pain, and, risk for compromised resilience (Ackley Ladwig, 2014).After hypothesize clients factors, it is necessary to develop intervention, which can develop to acquire the goals settled.The interventions are hypothesis to direct care the client. It is based on the conservation principles conservation of energy, structural integrity, personal integrity, and social integrity the goal is to maintain wholeness and promote adjustment for the client (Alligood, 2010). In this case, Mr. D. has broad interventions in his case, which begins in the self-care to social involvement. The surgical wound he needs to have information about how caring it. The nurse needs to teach about alter and changing dressing though some indications of infections in the surgical wound, so he can contact his doctor and/or nurse to verify this process. Medications to control and relieve pain are necessary to know, so teaching about it is fundamental. Although he has different type of cardiac medications, he needs to know all of them besides analgesics and nitroglycerine drug for angina if he develops coronary spam.Nevertheless, nurse helps in develop plans for the process of adaptation, which must be approved and oriented by Mr. D. This time for adaptation involves his recovery and after that for the process working in the daily routine. In the same time, he needs to be taught by the nurse about his disease and process of illness, so as much information (knowledge) he has, more easily the process of learnance occurs. This explanation does not need to be said only one time, but in the different consults, which are taciturn for him. Consequently, in the process to teach and manage his adaptation, working restriction must be considered because he is a farm, so a rouge part of his job needs to be revised provided that small portion of exertion. Thus, a holistic view for the mental process needs to be evaluated because in the process of adaptation a decrease in the level of self-pride occurs although it can develop mental disorder such as depression. Mr. D. has an increase factor in this part since he is a farmer, so restriction in the working routine facilitates this occurrence. Controlling it, community support (friends) is one method helping in his farm, so he has his job done with some help and regulating anxiety and other mental circumstance. Therefore, intervention is a primordial aspect in the process to care the patient, so it needs to have a holistic view to promote better quality of life not only for the client as well for his family.The last process in the Levines nursing process is the military rank. The evaluation refers to the observation of organism (client) response to interventions. In the decision making assess the hypothesis to verify if it has done a support for the hypothesis or not. If the plan has not supported by the hypothesis, it is revised and proposed a new hypothesis to be applied (Alligood, 2010). Mr.D. and his nurse will evaluate his intervention knowing the quality of it, so modification and revisions may be necessary to do to provide better care in his process of life. Otherwise, all the process to adapt and provide health care is lost. Hence, evaluation is extremely necessary, and nurses must do it in every single client, as much it can be necessary.Finally, an action plan with a model of care is applied for Mr.D. The model of care more appropriate is the Expanded chronic Care Model (ECCM), which has expand the focus of chronic care management toward health outcomes for client and community. This model expands the client to community a large view in the p rocess of care, and support in all directions is provided to guarantee adequate quality of life (Kramer-Kile et al, 2014). The plan of care for Mr. D. some aspects to provide care and adjustment in his life are emphasize. Fist, teaching he and his family (first caregiver) about how to care and change the dressing in the surgical incision, and provide a nurse (in his community) to check weekly in his house if the surgical incision has been cared correct so as his process of adaptation is been dealed. Second, teaching about the illness and illness course, and it provides a focus in some chronic concepts such as sexuality, adaptation, isolation, stigma, and cultural. Also, provide support to understand and accept these concepts are essential.Then, involvement in community is necessary, so it avoids social isolation and increase self-esteem. Friends support is necessary, and they may help in the farm working, so Mr. D. could reduce psychological pressure because of the job. Fourth, p sychological evaluation can determine if it is necessary to use antidepressant drug because a rouge change in his life has occurred. If necessary this type of drug, he needs orientation how to use and side effects that it can cause. Still, teaching about cardiac medication is significant, so it reinforces the management the correct time to take and side effects, which may be possible to occur. Fifth, cultural aspect about incapable may develop because he began to be cut back in his job. A support comprehension, which describes that he is capable to continue his activities, is decisive, so he is capable to do activities although some restrictions such as avoid high level of effort are necessary restriction. Sixth, body compute is another factor present because scar of the surgery will be present for the rest of his life, so understanding how to accept this aspect in his body is crucial for the quality of life. Last, family support in the process to accept the disease and provide ad equate adaptation is required. Nurse may provide sources for his family to understand and know how to manage this illness in order that Mr. D. has more acceptance and provides involvement in his family in the process to care him. Indeed, the nurse and client develop action plan, so both must have agreements, which provides better care and process of adaptation. A revaluation these plans are indispensable, so adding or taking off part this may result.In brief, in the following paper was described Mr. Ds story, some chronic concepts, which are related with his history, a succinct nursing theory description, which was Levines theory, the application the Levines conservation model theory for Mr. D., and action plans with a chronic care model may be applied for Mr. D. I have written this paper based in Mr. D., who is my father, and I thank him to have been given all this experiences for me in the process to care and manage his chronic illness. It is not easily to accept a new situation i n the life and beginning to have adaptations in the inspected period of the life, so every chronic disease and illness are difficult to manage if the family and client do not have correct support to confront it. As a result, nurses need to have as much as knowledge possible doing research and applying nursing theories to provide better care and support for their clients and clients family.
