Case Study #3
The cell infrastructure in East Africa is very limited. Ethiopia, one of the more developed East African nations, has a mere 5 of every 100 persons using a cell phone, and the resulting infrastructure is weak. Somalia, on the other hand, has virtually no infrastructure. The capital, Mogadishu, is just now receiving local cell phone infrastructure, as well as other population centers, but the majority of the country is without it. Good cell service in East Africa is terrible compared to bad service in the US, yet they are making inroads in countries like Ethiopia.
How does telemedicine treatment work in theory? Find an example of the real world, and explain how the reality compares to the theory. Discuss whether current telemedicine is feasible in East Africa. Discuss the feasibility of future telemedicine practices in East Africa.
Telemedicine works by having the data relayed to another doctor, having that doctor diagnose it, and have the on-site people treat it. Current telelmedicine is maybe possible in a limited amount in East Africa, but overall, it would seem to be relatively unreliable in relation to the poor infrastructure in East Africa.
Discuss the feasibility of telemedicine for training purposes.
Telemedicine for training purposes may be slightly more feasible, as the unrealiblity would not threaten the patient's well being, and they can train whenever there's a good connection.

Gift of Fire 4.8, 4.10
a.) Is this kin d opf problem more likely to occur with computerized records than with paper records? Why or Why not?
This kind of problem is not more likely to happen with computer records, as the possibility of two different databases using different codes is just as likely in paper records.
b.)Solutions?
A standardized code system to be used in every school would solve this problem and prevent any future confusions.
4.10)No, I don't think the schools would have reported the scores had been higer- they would have welcome it, because it would have improved thier standings in respect to other schools.

Portfolio Check #2 Part 2
One possible solution would be to simply not change the protocol, while another solution would be the possiblitiy of further testing of the protocol, and very gradual introduction of this protocol. And I do have access to a number of sources to research this topic; New York Times, BBC News, Wall Street Journal and Wired News, as well as having access to HTTP: the definitive guide, via Google Books.

Portfolio Check:
The area of impact fpr this article is this time is arts, entertainment and leisure, as the majority of liesure time for some people is spent on the internet, and is one of the largest entertainment providers that exists. I have already done the politics and government are of impact. This article was published November 12, 2009, which is more than a year into this course. This article does raise a social issue; which would be the reliability of the new protocol.

Case Study Problem #2
There are systems that can be downloaded from the Internet and completely supported via the Internet. This may make the employment of this in Africa easier for them to achieve. The software would run on normal operating systems, and would prevent the need to buy pre-built hardware to support the software system, when it could be run off of normal operation systems. Although there are operating systems which can be bought with pre-manufactured systems, it may be cheaper for the African countries to go with the Internet supported systems. The advantages of getting a pre-built system would be the fact that they would be abler to get consistent support and possible on site backup, with personnel training and the actual systems at hand, and close by. A disadvantage would most likely be that a pre-built system would have components that are designed to work with more advanced technology than they might have.
Custom systems on the other hand, may be a very useful for the East African clinics. These systems are specifically designed for the clinics, and would have none of the compatibility issues that the pre-built systems would have. The prices for this would be predictably higher than pre-built systems as would the maintenance costs, but at least it would be capable and easier to use with what the countries have at the location. The advantages of this system would be that the technology would be specifically designed for them, and would therefore be compatible with the tech they already have, and any they are planning to buy. Though the disadvantages would be the fact that it is much more expensive than prebuilt systems.
I would recommend that the government of the western province spend the extra money and purchase a custom built system, as this would have greater capatability would be easier to use, as well as the fact that they would have more back-up and will be able to use easier with thier current technology.

FBI fingerprint database
The IT development emerged through the application of the biometric technology that already existed by the FBI.
This technology gives the FBI many advantages over the old system, one of the main ones being speed. The computer can compare data much faster than a human, which allows the criminal to be caught much faster. There is also the advantage of the computers having more data for to compare (capacity), as they will be expanding the database, making the comparisons more capable as they can now compare more people, allowing them to search a larger pool of persons, which is also a more thorough search, as there are more persons who can be searched. The system is also more accurate, as the computer is able to eliminate bias and find the match to the data they are given, which allows the FBI to more accurately track down and arrest the actual criminal, though there is the potential that an error, or the corruption, as well as possible hacks into the database.

Portfolio Topic Check Part 2
Two viable solutions would be a nuetral agency to keep track of all the computers capable of imitating humans and to prevent them from gethering info or tracking people. Another would be a law requiring a warrant before a government agency could use the computer to track citizens.
Three possible resources to conduct further resources are potentially Wired News, the New York Times technology section, as well as the BBC technology section.

Portfolio Topic Check Part 1
The area of impact that this would fall into would be politics and the government as the success of this endeavour would allow various governments and enterprises to gather information on people without there knowledge.
Yes, it was published after I started this course. It was published on September 9th 2009.
This article definitly raises social and ethical issues. One of these would be the "risk" in giving computers the ability to behave like humans; ie. you could no longer tell who was human and who wasn't without seeing the actual computer.

Case Study Problem #1
The most feasible IT system that would allow data to be accessed and transferred would be the internet, but, with the exception of village A, the outlying villages do not have internet access. One way to solve this would to get both villages connected to the internet via a new line from Oobunta to both villages B and C, and to upgrade village A's connection, as it is intermittent at best. The most reliable connection would probably be a fiber-optic cable from Oobunta to each village, but that may be too expensive, in which case they should go with a regular cable connection to Oobunta. As for each village it may be beneficial to give each a Wireless network, instead of wiring every computer. There is another option to connect the villages to Oobunta via the internet that is potentially the most appropriate; as they all have access to a cell network it is possible they coulb utilize USB Modems to access the internet using the already present cell networks in the region. This would be both cheaper and more reliabe, as the land lines could become damaged wheras the USBs are much easier to maintain and to replace.
I searched through Cape Cod Hospital's web site, as well as the web sites of Jordan Hopital and Mass General, and none of them mention the computer network supporting thier hospitals. When I searched more broader most of the articles I found were debating the importance of computer networks in hospitals, not actually informing about the hospitals use of information technology.
The stakeholders in this situation are the villagers, the hospital personell and the local government. The villagers would have the advantage of gaining better care, but if the local doctors come to rely on the internet to mucha nd end up misdiagnosing, a villager could die. As for the doctors, they may gain the ability to treat more diseases, but could also misdiagnose if they could become too dependent on the internet. If the program succeds the local government could gain prestige, but if it fails, heads could roll. The doctors on the ground would be responsible for the treatment of patients, but the local government would be responsible for the actual network implimented. The doctors and local government should be held accountable, but a scapegoat may end up taking the fall. Any laws that govern the medical community in the country they are in would apply, as would any policies regarding the treatment of patients, as well as conduct online.
