introduction to information technology
[6/4 -- Open Source -- ]
Begining the class Dr.Yoon says we something that This weeks is last class this semester.
This semester's last class subject is Open Source.
At first We learned resistance. resistance are tactics and means to oppose the strategies of “The Prince” Prince means Microsoft,Google,Naver etc.
While the prince tries to “divide and conquer,” the resistance tries to overcome the imposed isolation.
Nowadays, few people have strong capital and high technology. they have a decision many people. for example, strategies of “The Prince". Resist for this, many things
Examples of “electronic disturbance" are virus, trojan horse, worm, bomb, back door.
Virus is a cracker program that searches out other programs and `infects' them by embedding a copy of itself in them.
Trojan horse is a program designed to break security or damage a system that is disguised as something else benign
Worm is a program that propagates itself over a network, reproducing itself as it goes.
Bomb is a code surreptitiously inserted in an application or OS that causes it to perform some destructive or security-compromising activity whenever specified conditions are met. back door is a hole in the security of a system deliberately left in place by designers or maintainers.
Open-source is fun. Fun factoryusers are develoopers or designers of the programs, also. When I was in high-school, I used a PMP. Some functions and visual designs of it are open-source. Thus I did download many funny skin for my PMP. In that time, I was so fun. Thus I think "Open-source" gives some funny, enjoying, happieness to users. As a result of users can use some products during long times, interestinglly.Then, I could know many concepts of virus, troy horse, bomb, backdoor, worm in this class. Maybe, I will study them easyily, when I learn to subjects realated to networks.

5/21,5/23 PUBLIC & PRIVACY
introduction to information technology
[5/21 , 5/23 -- Public & Privacy -- ]
This week's subject is Public & Privacy. Privacy is a culturally specific definition
We do not care public and privacy In usually. and Its accuracy is very low.
This class is chance to me that conclude my privacy information boundary.
I learnd surveillance . Surveillance make what society act efficiently. And that make systemNowadays, That system make problem. Example, human estrangement. But, Banjamin Frankrin's say, That is not strange. Surveillance exist on our life. Peoples don't want to absolute free. Peoples need safety in restriction.
This weeks , Prison privacy structure is remind on my memory. That similar to garden at first, but I under stand this picture, I understand this structure too.
Data mining efforts are directed toward the generation of reles for the classification of objects, discriminating or distinguishing between two related, but meaningfully distinct classes. Also, let's see about types of data mining. 1. descriptive : compute a relatively concise, description of a large data set. 2. predictive : predict unknown values for a variable for one or more known variables.
Technologies and architectures of privacy-technologies and architectures do not independently determine what is public and what is private technological determinism. Then, we will learn about authorship&ownership next week.This week's lecture learned that we can adjacent life. It is interesting.

5/14,5/16 HUMAN
introduction to information technology
[5/14 , 5/16 -- Human-- ]
This week we learned about HUMAN.
What is substitution for human organ?-There are many substitution for human organ. For example, glasses substitute our eyes. and clothes substitute out skin, and cel-phone substitutes our memory, pinset substitutes our hands, and so on.
There are many things that , For example, glasses substitute our eyes. and clothes substitute out skin, and cel-phone substitutes our memory, pinset substitutes our hands, and so on. And we are not free of them- organ. If how we can do if our body has gone. Like accident and so on. If so we suit artificial body. we saw lots of movie or animation on it. We so-called like this person to cyborg. Than we call this people human?or machine?
We are radically altered by a medium.continually, media technology can see that emphasized. Also, media studies is the theory and practice of exploring how people and things are connected, reflected, extented, reconfigured, and separated by technologies.
Next item is cyborg. In ordinary I can hear that some part.
for example, movie, music, and television. But I don't know its detail definition or information . I learnd it in this class. So I am understand that.
One of good sample is 6million man. This man is retired but his cyborg body ability is better than nomal body. So, people more prefer as his/her body as his cyborg body than nomal body
I think Our body is very mistic. We can improve our body, and invent another system and machin by our body's feature. then It is so suprised and convenience.

5/7, 5/9 COMPUTER GAME
introduction to information technology
[5/7 , 5/9 -- Computer Game -- ]
Today main theme is Computer Game. At ordinary I don't like game. But My friends is like it . so I usually watch that my friedns's play.Game is composed by engine(graphics, physics, ai,and so on), movie. And Mod of game is various. RPG, Action, Simulation and so on. Game is not just toy. Naturally, Mod of game definited by general public or developer. I love game. especially RPG. I throb and see game in dream When i kid. Not only addict. I an sad when I clear game and see ending. That feeling like farewell to friend. I love story, character and world of game.
In fact, answer is nothing. There are many answers of the question. We can answer that popular game is good game. There are two perspective of game story. One of them is Narratology. People following that talk game’s story was from literatures. However, People following Ludology do not talk that. There are two issues to consider from film theory. One is a identification. We can think he is me or she is me, when we control a character of the game. Two is a space. Space invented by programmer makes us. Then technology embody something in that case.
Boy’s game & Girl’s gameThe standard for social gender is related in games. too.The ‘male gender’ not only means physical thing but also social gender.So we have to think about social gender of person. And the social gender demand to behave to the gender standard. [ex: boy’s color & girl’s color, punishment method…]So, I think boy’s game & girl’s game could be exist and already so many people is doing this.

4/30,5/2 COMPUTER-AID
introduction to information technology
[4/30 , 5/2 -- Computer-aid -- ]
This class we learnd "Computer-aid" Let's think about ethnomethodologists.
What is the ethnomethodology? An ethnomethodology is that how people make sense of the social world. Ethnomethodologists assume that social order is illusory. They believe that social life merely appears to be orderly; in reality it is potentially chaotic. For them social order is constructed in the minds of social actors as society confronts the individual as a series of sense impressions and experiences which she or he must somehow organize into a coherent pattern.
We watched Modern Times that movie performed by Charlie Chaplin. The movie represents the era of the beginning of the modern society. I think that the movie is related with CSCW (computer supported cooperative work) and it is a little bit humorous. So what is the CSCW? As I mentioned before, it is the cooperative working when we work by using computer and it is decide what to do. For example, there are Photoshop, illustration. These softwares are instead of us. It means that we can draw a straight line by using these tools and we do not need do whole part of working. There is CAD which is used to architecture. It is usable not only architecture but also products design. CAD is convenient to draft what you construct and design so numerous designers use CAD when they draw a plan to construct a building. Therefore, as we use the software which is like CAD, Adobe Photoshop, Illustration etc, we can make the relation with the topic that is mentioned before. The topic was that technologies embody social, political, cultural, economic and philosophical ideas and relationships.
In this class, at first, I think this subject is very common and easy for me. but it is very hard. so a don't understand some part. but I think that Comeputer-aid is very important and very useful part. It is necessary for us.

4/23.4/25 HUMAN COMUTER INTERACTION
introduction to information technology
[4/23,4/25 -- Human-Computer Interaction--]
This class was related to Human-computer interaction called HCI. HCI is just part of computer science. However we didn’t look around HCI in it’s perspective, we did HCI in art, ethic perspective. Key point of it is that people often interact with media technologies as though the technologies were people. Then ironical thing was that HCI related to ethics. Moreover aesthetics and design do too. We looked around a history of HICI as tools. Surprisingly, we already studied them : Bush’s memex, Ivan Sutherland’s sketchpad, Engelbart’s mouse and GUI and word processing, Nelson’s hypertext, so on. World wide web using now is it, too. Interest thing is that initial generation of HCI concentrated only tools(mouse, key board…) as method based on industrial design. However we use and invent the method over it having a purpose.
Then, what is the purpose of tools of the HCI? Answer is that the devices announce human’s direction or indication to the computers.In except, many field including the Military, Universities, Government, Companies were interested in the HCI. Thus they fund it.Finally, HCI met the AI. However there was a question : Should the computer act like a person?. There were
two opinions. First, the agent similar to system of Amazon.com . It can do some things human does not command. The other hand, the direct manipulation can do only some things human does command. Then we should to consider to give some meaning or define(co-construction of meaning). We watched some movies of the HCI, after.We recalled the ELIZA. ELIZA answers our questions but they are not correct. However it is not fail. It is so human.Then, we can do Johnstone’s algorithms. First, point a person, and make him to say something. He will say “I can’t say something.”(shying). Then we should to say to him that “Ok, then can you guess the answer in my mind. Give me questions”(in fact, we have no idea). Then He will start to question and get out of pressure of talking. When we answer the his question, we will have some ruleAs a result, he will happy to know right answer and shout to it. What we draw on it?
Ethnomethodology simply means the study of the ways in which people make sense of their social world. Ethnomethodologists assume that social order is illusory. That is order of world is defined by my taste. It is far from mind of 1600s.HCI is from Films. Technology inspires films and film inspires new technology. The new technology develops the HCI, so we can anticipate developing of the HCI in the films. That is, Films are anticipating or inspiring HCI.

4/11 ARTIFICIAL INTELLIGENCE
introduction to information technology
[4/11 -- Artificial Intelligence--]
This week's theme is Artificial Intelligence(A.I). Some years ago I have ever seen movie 'A.I.' . That movie made to be impressed me by a splendidly screen, and humanity. In some respect, that story is unimaginable. but it is very surprising sudy.
Artificial intelligence is a type of computer technology which is concerned with making machine work in an intelligent way. This class we learned Alan Turing. He is founder of computer science, artificial intelligence, mathematician. and so on. He made one game. That called "imitation game." The game is playing by 3 people. Man and woman stays in a room apart from the other. and one people perform another sex. than interrogator guess and determine person's sex. Can you guess it? That will be difficult than you think. We should judge by logical or context or flow conditions.
Marvin Minsky defined AI. That is the science of making machines do things that would require intelligence if done by human.
So Artificial intelligence need research areas. For example representation, languages, understanding, vision(computer vision system), robotics and so on. But researcher met a difficulty research. so AI couldn't cope with all. There are problems. but It is algorithm programming. So funding was stopted.
Planning as a technical problem is GPS. GPS is general problem solve. It is what is known in AI as a 'planner' It need that a full and accurate model of the " state of the world."
