Assignment 7 - Essay Example There are three main components that every person as well as design should observe so that the feelings of the people involved are competently taken care of. The three aspects that need to be taken into account so that feelings of other people are taken seriously especially in design include appearance, behavior and their experiences or expressions. The three aspects need to be appreciated in the interaction with each individual so that they are able to connect with us. First, appearance or the visceral aspect as described by Norman (2004) describes the way we are able to appreciate how individuals react to the outward appearance of the product design. It is even imperative that we understand that appearance is even more important that functionality since most people are likely to perceive attractive things to be more user friendly than unattractive ones regardless of the real facts. The design should also take into account of the likely impact it may have on the pleasure or effectiv eness that will be attained by the potential users. In effect, to be able to seriously take into consideration the people’s feelings, we should be able to provide them with products that are likely to revitalize their fond memories. Lastly, it is important that the products reflect the individual’s rational and intellectual principles and that they are able to associate with it by even giving an explanation of how it functions. Norman (2004) has suggested that computers should therefore take the emotional component through well designed programs that are able to take into account the user’s feelings. It is quite strange but equally hilarious to think that computers can have emotions or at least, have an element of creating emotions. To some extent, I agree with the writer to the extent that computers and other digitech products should have basic elements of emotions so that they are able to be more users friendly. Whereas there is a big challenge of perfectly cr eating programs that will be faultlessly respond to different emotions and handle different personalities, it is important that computers are able to create some aesthetic value apart from the normal usability features. It is important that computers and other technological products are able to identify with historical and memorable events that people are able to connect them and not view them as insensitive tools. The writer is therefore right when he states that there should be a human part in the working of machines. He gives a good example of robots that he believes should do more than just assigned tasks so that they are viewed as more capable. However, in as much as the concerns of the writer may be genuine in addressing this great weakness of computer related design, it is still inconceivable to think that computers will perfectly fit to relay emotions and relate with different personalities. Like every being has different emotional frame and they may vary according to the en vironment or some historical happening among other things, computers may need to have complex systems that will integrate all these aspects in a single program that is likely to take immense efforts and massive resources to achieve. A2. The Philosopher’s Tool Kit Wittkower (2008) has raised an important component in product design by using the example of an iPod and the philosophy behind its much fanatical following. The author raises four pertinent issues that consumers may want

Bone Marrow Transplant & Donation Essay Example | Topics and Well Written Essays - 1750 words

Bone Marrow Transplant & Donation - Essay Example ICU stay would usually be hectic with frequent monitoring, institution of mechanical ventilation, renal replacement therapy and continuous infusions. The conditions for doing bone marrow transplantations, selecting the donor if doing allogeneic transplants, the actual surgery, the prevention of immune suppression after the surgery and ensuring the survival of the patient have heightened the risk of the ominous event that is bone transplantation. This paper is exploring the biological features including the anatomy and physiology of bone transplantation investigated in the various researches. Initially the normal anatomy and physiology have been described so that the reader gets a better picture of what is intended by this research. Normal anatomy and physiology of bone marrow The soft tissue that lies in the spaces between the bone trabeculae of flat bones is bone marrow. Blood vessels, nervous tissue, phagocytes, stem cells and blood cells at different stages of maturation are found in the bone marrow (Elgazzar, 2004). The red marrow has hemopoietic cells which are active while the yellow marrow is mainly fat and hemopoietically inactive. The bone marrow is essential to the human life as it provides all the blood cells: red blood cells, white blood cells and the platelets. The manufacture of the blood cells depends on the needs of the body. Active bone marrow is found mostly in the flat bones of the vertebrae (28%), pelvis (34%), the cranium together with the mandible (13%), the ribs and the sternum, (10%) and the proximal ends of the femur and humerus (4%-8%) (Elgazzar, 2004). The manufacture of blood cells is termed hemopoiesis. It begins in the human body at the fourth month of the intra-uterine life of the fetus. Within two months it functions more than the liver in the hematopoietic action. By birth, the red bone marrow becomes fully responsible for the blood cell formation. The cartilaginous epiphyses which did not have the red bone marrow at birth soon had it in the first few months of life (Elgazzar, 2004). The adult bone has active red marrow in the various bones different proportions. The usual conversion of red marrow is to the yellow marrow. However in certain pathological conditions, the reverse process occurs. Alterations to the distribution of the red marrow could change in conditions which are traumatic to the human body like surgeries, trauma or infections or malignancy (Elgazzar, 2004). Immune response Lymphocytes were the natural killer (NK) cells which were significant role players in the immune responses, both innate and adaptive (Olson et al, 2009). Lymphocytes provided the response to virus attacks, microbes and some tumors. The NK cells were white blood cells produced in the bone marrow and then moved to the region of the spleen, liver, lung, blood and lymph nodes where they resided (Olson et al, 2009). The period of maturity from a bone cell precursor to maturity came to 28 days. When an attack from viruses or mi crobes or tumors occurred, signals reached the NK cells which then migrated to the sites of attack through the expression of inflammatory chemokine receptors by virtue of their homing behavior (Olson et al, 2009). At the key sites, the NK cells entered the lymphoid tissue in the lymph nodes and non-lymphoid tissue in
