Chapter 13 Copyright and Fair Use

When it comes to copyright law and the application of fair use exceptions, ignorance is definitely not bliss! Learn how to educate yourselves and your students and avoid making a costly mistake! 
You really did plan to find time over the summer to familiarize yourself with the latest information on copyright law. You absolutely intended to look up the fair use guidelines for using technology resources. You truly meant to create a classroom copyright policy, locate agencies that grant permissions to use copyrighted materials, write a template for a permission request form, and locate sites to teach students about the value of original work and the societal benefits of obeying copyright laws. You just had a few other things to do. 
So now you have a student who wants to include audio of a Beatles song in a multimedia presentation about the 1960s, another who wants to include the poem "Casey at the Bat" in a report on the World Series, and a third who wants to post photographs of Biden and Obama to the class Web site. 
What's an educator to do? Read Education World's five-part series on copyright, fair use, and new technologies, that's what! We did the work so you wouldn't have to!

Chapter 12 Knowledge Management

Samsung Electronics’ Knowledge Management 


System


In April, 2009 the Visual Display Division of Samsung Electronics' Digital Media Business had just completed work on a ground breaking high-resolution LED TV. The company was vigorously engaged in a massive campaign to announce this remarkable product, which was expected to take the global TV market by storm. The Visual Display Division was poised to take a well deserved breather from the marathon development and production phases of this landmark project and take a moment to bask in the glory of their achievement. Shortly, they came to understand why it is often said that no good deed goes unpunished. The Division was blindsided by the call to initiate a new mission. Samsung management issued an edict: The Visual Display Division will roll out full-HD 3DTV within a year. There was no time to waste resting on their laurels, it was time for the division to get cracking .... again.
Korea's Hyundai IT had developed a 3DTV in 2007 and Sony was making systemic preparations to beat Samsung Electronics to the market with a 3DTV of their own. There was little doubt that Samsung Electronics was playing catch-up. The best and the brightest of relevant departments were assembled to staff the new mission. Two task forces, identified as C7000 and C8000, were immediately established. The task forces dusted off the results of studies on 3D that were conducted over the past several years and began to give them a fresh look.
At this time Samsung Electronics’ knowledge management system (KMS), called the Test and Error Management System, or TEMS, was called upon to play a key role in the project. TEMS, which is known by Samsung electronics engineers as the "treasure chest", contains all information related to each step of Samsung Electronics' product development. The one-year process of developing 3DTV is also enshrined in TEMS, as is to be expected. In fact, in addition to the stellar efforts of the highly committed team in the Visual Display Division, it was Samsung Electronics’ knowledge management system that was responsible for closing the gulf between them and their rivals and making it happen in just one year.
Samsung closed the gulf between its rivals after adopting its knowledge management system
Samsung closed the gulf between its rivals after adopting its knowledge management system
In his book, Management Challenges for the 21st Century, Peter Drucker noted "The 21st century is a knowledge-based society, where knowledge workers are the most important factor of production. In other words, conventional economics' production factors, the 4Ms - Man, Machine, Material and Method - will be replaced by workers armed with knowledge. Thus, management of knowledge workers will form the foundation of corporate management."
As the technology of TV has evolved to deliver HD 3DTV, so has the methodology of producing world-class products and maintaining a competitive advantage in the global marketplace. Samsung demonstrated in practice what Drucker proposed in this book, that by leveraging the value of their KMS, they were able to achieve the goal of HD 3DTV in a year. This is a fact that is surely not lost on their rivals.

Chapter 10 Information Technology

8) Identify the Pros and Cons of Information Technology.

Information Technology Pros

1. The world got flexibility
What we think, do or plan must be shared with our co-workers, colleagues and friends. The internet technology has advanced this system to a great extent. The telephone idea (by Alexander Graham Bell) has been modified and made as Cell Phones to increase more flexibility in communication and talk to our dear fellows whenever we require!
2. The sense of responsibility has increased
Let us take ‘Barack Obama- USA President’ as the figure. With the use of networking sites (Twitter and Facebook), blogs, social bookmarking, the leader can approach to the world whenever necessary and we can receive the news and updates which he has done (or wants to be done by us) within a very short period.
3. Easy thinking & evolution in transportation


To think and to research, we need resources to find what our past people has thought, what quotes they have left for us (+information + theory). We can find them by a single click in search engines (specially Google, Yahoo!). By getting a clear cut idea, we get the chance of contributing the world with new technological ideas and inventions and share what we have learnt throughout our lives.
And throughout the ages, it helped us to evolute the transportation strategy which helps us to visit from a place to another by (Roads, highways, air, water and in the skies!)
4. Saves thousand of lives daily
So, by the point heading I hope you understand I am referring towards Medical Sector development. Each day people are getting relief by the perfect use of Medicine, Hospital Technology with addition of (X-Rays, Laser Treatments) and more on the queue. By the combination of the World Health Organization, various fatal diseases can be overcome and just expelled from specified countries by quick plans and ideas.
5. Increase the sense of Human Rights
The technology can remind of our human rights, basic needs and give updates where relief or worldwide help is necessary. During earthquakes, terrible floods, while co-operation is necessary the World Wide Web can help us to collect the donation by a desired amount.
It is not possible to just figure out everything about the good and bad sides of Information and Technology within a page and article as because it has mixed with every aspects and corners of our lives. Rather, let us look at the side effects, bad sides (cons) which IT-sectors have brought to the Human Society.

Information Technology Cons

1.It has taken away people’s Privacy
As IT-Sectors have wined the people’s heart worldwide. People are here to share and store any kind of information, private date in their hard drives and private online databases. But due to some Cyber-Criminals, nothing is SO Safe both online and offline. If someone becomes a bit careless, s/he may needs to pay high for it. (It’s serious).
2.The online community is not safe for Family anymore
Children under age may often share Cell Numbers, Private Email Address which can be hacked by people and can pass it to the criminals who have a blue-print to harm the society. And people are loosing credit card privacy and other payment processing options. Again, there are some sites created by Nasty Guys, which can lead under eighteen teenagers to a different path – That Is Going To Bring Harms To The Nation.
3. It is going to damage a Human’s Natural Power
We can think, gather human principles (ethical knowledge) and make co-operative relationships between friends and families. But due to harmful aspects of (IT) people are becoming fully technological based. And it can bring huge damage to the society as its taking away the natural thoughts and organic ideas.
4. It can bring World Destruction without Efficient Administration
This is an extra point which I am writing by remembering various Science Fictions. Great scholars have though about the matter wisely. Til now, we (humans) are possessing the leading place in the world and administering the computer technology. But a day MAY come when the technology is going to administer us in all aspects. It may probably happen that we are converted to the slaves of Technology.
So, by this cons I am not trying to tell that Technology is here to bring harms only, because I myself is a technological man who passes 24 hours browsing computer and talking on phones. But as a part of human society we need to give up a look at the both sides of IT.

Chapter 11 Information Systems

Toyota is all about the customer. We hear a lot — and I’ve written a lot on this blog — about the Toyota Production System, anglicized in the United States as Lean, but we haven’t known much about the role of Information Technology at Toyota.
Baseline Magazine has a great article on Toyota; specifically, the role of technology at Toyota1:

And behind TPS is information technology—supporting and enabling the business processes that help Toyota eliminate waste, operate with virtually no inventory and continually improve production.
Technology does not drive business processes at Toyota. The Toyota Production System does. However, technology plays a critical role by supporting, enabling and bringing to life on a mass scale the processes derived by adhering to TPS.
And more,

Over the years, Toyota refined a number of other concepts and production methods that support the two central TPS pillars. And behind each of those pillars are information systems, supporting and enabling the processes:
  • Just-in-time: Toyota employs one of the most sophisticated supply chain systems in manufacturing, working closely with suppliers to ensure that parts arrive just when needed. For example, when a car comes out of the paint shop in Georgetown, the system sends seat supplier Johnson Controls an electronic message detailing the exact configuration of the seats required (leather upholstery, bucket seats, etc.); Johnson Controls has four hours to ship those seats to the plant in the exact sequence required. The instructions are provided by Toyota’s proprietary Assembly Line Control System (ALCS) software.
  • Jidoka: At every stage of the assembly line, Toyota employs devices allowing workers to stop production to correct defects. Such devices may be as simple as a rope strung above the assembly line, or a button that can be pushed. In other cases, it is sophisticated monitoring software such as Activplant’s Performance Management System, which can alert operators to problems with equipment or robots in real time.
  • Kaizen: This is a system for continuous improvement. Toyota constantly looks to improve its business processes by finding ways to take Muda (waste) out of the system. It can be as simple as moving a tool to an assembly station so a worker does not need to waste time walking to get the tool. Or it may involve technology, such as allowing dealerships to swap car inventories using the Dealer Daily, an Internet portal, so customers are not left waiting longer for the vehicle they want.
  • Andon: Wherever possible, Toyota uses visual controls, or Andons, such as overhead displays, plasma screens and electronic dashboards to quickly convey the state of work. On the assembly line floor, for example, overhead Andons tell a supervisor with one glance whether the station is functioning smoothly (a green light), whether there is a problem being investigated (yellow light) or whether the assembly line has stopped (red light). Newer plasma screens, tied into assembly line equipment, provide even more information such as which machine malfunctioned, the operator and the exact conditions (speed, temperature) when it broke down.
  • Poka Yoke: Toyota uses a range of these low-cost, highly reliable devices throughout its operations to prevent defects. A PokaYoke may be something as simple as a tool holder with an electronic sensor, or it may be a light curtain, a beam of light that sends a signal to a computer when a hand or some other object interrupts its flow. The curtain can signal a warning if, for instance, a worker fails to pick up a cotter pin, bolt, nut or some other required part.
  • Genchi Genbutsu: The literal translation of this term is, “Go and see for yourself.” Rather than hear about a problem, Toyota requires its workers, team leaders and executives to go and see a problem directly and to work collectively on a solution. At least 50% of Toyota’s information systems workers are stationed at plant sites to work directly with operations.
A case in point in how technology supports TPS and the customer:

In all, the Dealer Daily [Toyota's application for car dealers] incorporates more than 120 business applications, and like all Toyota initiatives, it is constantly undergoing Kaizen to look for more improvements and opportunities to remove Muda. Case in point: Toyota recently added the capability for dealers to find out which vehicles it has in the production pipeline, and make changes such as switching a cloth interior to leather. (Dealer Daily is integrated into Toyota’s mainframe systems through file transfer protocol and System Network Architecture [SNA], IBM’s proprietary networking architecture, although Web services are now being explored.) By logging in the next day, the dealer can find out if the changes were received in time and accepted. This allows the dealers to more closely customize orders to actual customer demand.
Here’s a look at the current proprietary technologies at Toyota, all modified to support the business:

Chater 8 How do search engine work?

     The term "search engine" is often used generically to describe both crawler-based search engines and human-powered directories. These two types of search engines gather their listings in radically different ways.

Crawler-Based Search Engines

     Crawler-based search engines, such as Google, create their listings automatically. They "crawl" or "spider" the web, then people search through what they have found.
 If you change your web pages, crawler-based search engines eventually find these changes, and that can affect how you are listed. Page titles, body copy and other elements all play a role.

Human-Powered Directories

     A human-powered directory, such as the Open Directory, depends on humans for its listings. You submit a short description to the directory for your entire site, or editors write one for sites they review. A search looks for matches only in the descriptions submitted.

     Changing your web pages has no effect on your listing. Things that are useful for improving a listing with a search engine have nothing to do with improving a listing in a directory. The only exception is that a good site, with good content, might be more likely to get reviewed for free than a poor site.

"Hybrid Search Engines" Or Mixed Results

     In the web's early days, it used to be that a search engine either presented crawler-based results or human-powered listings. Today, it extremely common for both types of results to be presented. Usually, a hybrid search engine will favor one type of listings over another. For example, MSN Search is more likely to present human-powered listings from LookSmart. However, it does also present crawler-based results (as provided by Inktomi), especially for more obscure queries.

The Parts Of A Crawler-Based Search Engine

     Crawler-based search engines have three major elements. First is the spider, also called the crawler. The spider visits a web page, reads it, and then follows links to other pages within the site. This is what it means when someone refers to a site being "spidered" or "crawled." The spider returns to the site on a regular basis, such as every month or two, to look for changes.

     Everything the spider finds goes into the second part of the search engine, the index. The index, sometimes called the catalog, is like a giant book containing a copy of every web page that the spider finds. If a web page changes, then this book is updated with new information.

     Sometimes it can take a while for new pages or changes that the spider finds to be added to the index. Thus, a web page may have been "spidered" but not yet "indexed." Until it is indexed -- added to the index -- it is not available to those searching with the search engine.

     Search engine software is the third part of a search engine. This is the program that sifts through the millions of pages recorded in the index to find matches to a search and rank them in order of what it believes is most relevant. You can learn more about how search engine software ranks web pages on the aptly-named How Search Engines Rank Web Pages page.


Major Search Engines: The Same, But Different

        All crawler-based search engines have the basic parts described above, but there are differences in how these parts are tuned. That is why the same search on different search engines often produces different results. Some of the significant differences between the major crawler-based search engines are summarized on the Search Engine Features Page. Information on this page has been drawn from the help pages of each search engine, along with knowledge gained from articles, reviews, books, independent research, tips from others and additional information received directly from the various search engines.

       Now let's look more about how crawler-based search engine rank the listings that they gather.

5 search engines on the internet



Visit AltaVista

     Actually don't bother. AltaVista is now an exact replica of Yahoo! search. Did Yahoo! take out AltaVista to minimize competition? Or because it was a better piece of programming? Seeing as AltaVista was once the exclusive search provider or the Yahoo! portal, it was probably the latter! Please note that I didn't realise that these were identical until time of writing!




Visit Lycos
     I checked Lycos out, believe it or not it was actually my search engine of choice in 2001/2002. The site has been completely redesigned, and although a redesign was severely needed.... it looks a little like a premium Wordpress template; in fact even I have that translation widget. It certainly doesn't look like a website worth $36m, albeit the monthly traffic and revenues dictate that. I was impressed with the search results though, it actually brought me four times the number of results for my chosen search term than Yahoo!, it also provides a screen shot of the indexed page which really helps with navigation - a feature which Google have recently brought in. I actually enjoyed seeing a different set of results for once, check it out for yourself at Lycos.com.



Visit Excite.com

     I decided to visit Excite.com and, frankly, it looks ghastly. In fact, it could be a throwback from 2001. I should be reserving my judgement to the search capabilities, but the default color scheme is off putting. I searched for the same term that I used for Lycos, and it brought me just 8000 results; Lycos found well over 1 million. The results themselves were uninspiring, several of the first page results led to domains which no longer exist. I think that I can safely assume that Excite.com is one which failed solely because it wasn't good enough to match Google and didn't have the right people managing the business. Unlike Lycos, which I felt was a great engine, this has nothing whatsoever on Yahoo! or Google. Visit Excite.com yourself to see whether or not you agree.



Visit ChaCha.com

This was the first time that I had visited ChaCha.com since it offered a human search, I once got banned from the service for pretending to be a lost child in a shopping mall. The less said about that the better. I searched for "How Many Elephants Left In The World" and was presented with an already answered question, as well as 6 questions which were very similar. The engine told me that a 2007 estimate suggested that there are in fact 470,000 to 690,000 elephants left in the world, that is actually far more than I had expected. Albeit, the question had previously been answered from Wikipedia. Another feature worth mentioning is that each search query also returns videos, in the left side bar I could watch any one of three videos about elephants! Now that is cool. I am a little torn with this one, I'm not convinced that this site is sustainable, and it brings you answers which you could simply find yourself in Google or Yahoo!; that said the design is pretty damn sweet and I can see how people could waste a couple of hours on ChaCha.


Visit Ask.com

     I quite like Ask.com now that is has re-branded as a question and answer site. Ultimately though, it is still a search engine. Asking the question "How many elephants left in the world" just brings up a list of relevant search results, whilst searching for the same search term as used for Excite and Lycos brought me some decent search results. Ultimately though, I still think that the only search engine on this page which deserves to rival Google and Yahoo! is Lycos. If only it didn't look like an advanced Wordpress site.

Help & Support Thai Flooding

In my opinion I will drain water from everywhere to sea and move everyone to hills side, dig canal deep more for catchment water, build more dam and the last thing is we should save our world before it too late because now our world is already destroy  and break. I will donate money for people who are poor too.
