Theories in Nursing Informatics

A. Change Theories

    Computerization of information system involves change, moving from paper-based environment to a completely paperless environment. It can be minor or major change depending on the maturity of the previous system, most importantly the users of the information system.

1. Roger's Diffusion of Innovation Theory (unplanned change) - examines the pattern of acceptance that innovations follow as they spread across population of people who adopt it.

2. Lewin's Change Theory (planned change) - describes the processes that occur in a planned change into 3 stages.

B. Information Theories

1. Blum's Theory - Blum stated in 1986 that computer functions can be categorized into 3 groups:

*data is processed

*information is processed

*knowledge is processed

2. Data-Information-Knowledge-Wisdom Continuum

C. Cognitive Theory - Cognitive science includes mental models, skills acquisition, perception and problem solving that adds an understanding of how the brain perceives and interprets a computer screen.

Pirates of the Silicon Valley (Reaction)

The movie tells us the big persons that has a big impact and world known about their inventing about computers and how it is started. Steve Jobs and Bill Gates, the two great persons who influence us with the Microsoft (Jobs) and Windows (Gates). It tells us how they are in person and in how did they first started especially when they are in college.

The artists were really look alike with the real face behind the movie. As you've research about Jobs and Gates, you would actually find that they are. It's a nice thing! As I've seen it first, I thought it was boring but as I've known it, it was actually how computers started. As it goes along, it really goes interesting. The funny thing about me is that I don't know actually who are the founders of it but as I've seen this movie, I know now about Microsoft and Windows and it's a nice movie that they produce it. It shows the success of them and they able to become World's popular and riches.

STORY:

*This tech-world biopic traces the fortunes of personal-computer companies Apple and Microsoft from their obscure dorm-room and backyard origins to their very public battle for corporate supremacy.

*Based on the Book: "Fire on the Valley: The Making of the Personal Computer"

*Berkeley 1971 - The scene cuts to the University of Berkley campus, 1971, amidst a tear gas and students rioting, a young Jobs and Wozniak dash to safety.

*Harvard University 1974 - Bill Gates's story starts when he is a Harvard student more interested in poker than classes. However, for Bill and his friend Paul Allen, there is one thing more important than poker or even Playboys, and that is, of course, computers. In following an ad in a trade magazine with some fast talking by Bill, and their collective genius, Bill and Paul are hired to start writing a program language for the new ALTAIR computer.

*Berkeley 1976 (Homebrew Computer Lab) -  Jobs and Woz unveil their latest computer. It is obvious that while it is Wozniak's genius that built the computer, it was Jobs' genius that sells it.

*Albuquerque 1976 - Bill and Paul had quit Harvard and Bill's fast talking at the computer company MITS (maker of the ALTAIR) earned them a signing bonus and a double in royalties for their BASIC programming language, with that, Microsoft is born. It is during these years in Albuquerque, fueled by his own manic personality that Bill does everything from having a midnight race with bulldozers, to racking up so many speeding tickets that he is arrested and jailed.

*Albuquerque 1977 - Microsoft's First Office

*Computer Faire in San Francisco 1977 - Apple Computers Inc. was the star of the Fair

*Microsoft Offices Seattle in 1980

*All-one Commune Oregon

*Xerox Palo-Alto Research Center - Apple “steals” the mouse as well as the graphics from XEROX.

*3 Mos. later, John Sculley fired Steve Jobs

*Steve Wozniak teaches computer in children

*Bill Gates is currently the World's Most Wealthiest Man

*Steve Jobs returned to Apple in 1997 and he finally accept Lisa as his daughter in his new family

Hardware

Personal computer hardware are the component devices that are the building blocks of personal computers. These are typically installed into a computer case, or attached to it by a cable or through a port. In the latter case, they are also referred to as peripherals. A computer case (also known as a computer chassis, cabinet, box, tower, enclosure, housing, system unit or simply case) is the enclosure that contains most of the components of a computer (usually excluding the display, keyboard and mouse). A computer case is sometimes incorrectly referred to metonymously as a CPU referring to a component housed within the case. CPU was a common term in the earlier days of home computers, when peripherals other than the motherboard were usually housed in their own separate cases. A power supply unit (PSU) converts alternating current (AC) electric power to low-voltage DC power for the internal components of the computer. Some power supplies have a switch to change between 230 V and 115 V. Other models have automatic sensors that switch input voltage automatically, or are able to accept any voltage between those limits. Power supply units used in computers are nearly always switch mode power supplies (SMPS). The SMPS provides regulated direct current power at the several voltages required by the motherboard and accessories such as disk drives and cooling fans. The motherboard is the main component inside the case. It is a large rectangular board with integrated circuitry that connects the other parts of the computer including the CPU, the RAM, the disk drives (CD, DVD, hard disk, or any others) as well as any peripherals connected via the ports or the expansion slots.
The expansion card (also expansion board, adapter card or accessory card) in computing is a printed circuit board that can be inserted into an expansion slot of a computer motherboard or backplane to add functionality to a computer system via the expansion bus.
An example of an expansion card is a sound card that enables the computer to output sound to audio devices, as well as accept input from a microphone. Most modern computers have hardware support for sound integrated in the motherboard chipset but some users prefer to install a separate sound card as an upgrade. Most sound cards, either built-in or added, have surrounded sound capabilities and 3-D sound effects.
Computer data storage, often called storage or memory, refers to computer components and recording media that retain digital data. Data storage is a core function and fundamental component of computers.

Internet

           

             My question is in the social life of a person especially to those who are in middle and high class society that can really surf the internet everyday is that "Can't you surf the internet the whole day or maybe not, can you?" I doubt it because they are born with social class and I believe that using internet now becomes the norm of us. I know that the Internet is hard to disappear because of the mainly reasons that it gives us information and easy access to get that information. There also other services on the internet like E-mail, Bulletin board system, Chat, Instant messages, Listservs, Newsgroups, Videoconferencing, downloading, and uploading.

Using internet really is addictive because there are so many web sites that we can actually browse like the vast approaching of the social networking's like Facebook and Twitter. Me and my family obsess that but I know how to manage my addicted to it. All I can say is that it's not wrong to use the internet but it's how the people use it because many of the reason that they actually abused it to the point that it's becomes immoral.

Network System

                A network is formed when two or more computers are connected by wire or wirelessly, for sharing of information and communication purposes. Network systems are essential to effective functioning of computerized healthcare information system. In a network system, only one copy of the system and application software is installed on the server or central computer and cheaper licenses are encoded to the client computers, thus the cost of maintaining the software is significantly reduced. A single printer, scanner or peripheral may serve all computers connected to the local network. The network allows several clients to access and make use of the same program simultaneously.

               Most networks operate under the client/server system including healthcare networks and the Internet. Under this scheme, a connected computer can be either a client, a server or both. A client computer has software that allows it to request and receive files from the server. The server has software that can accept these requests, find appropriate file, and transmit it back to the client. The client computer receives the transmission and interprets it.

                The clinical section with nurses using mobile and portable systems like electronic chart, PDAs, computer on wheels (COW) and electronic monitoring system, and wireless network connectivity would benefit most from wireless system. A virtual private network can be established at home or a remote office, say, for a chief information officer or healthcare administrator or physician. The home or office PC connects to the ISP server and transmits data via an encrypted channel to the HIS network server of the healthcare institutions.
