Illegal Storing or Sharing Activities of Copyrighted Materials – Your Personal Liability

The entire CityU community is reminded of the University's commitment to the protection of intellectual property and copyrighted material. When it comes to illegal storing or sharing of digital materials - whether music, video, text, or picture - the University imposes its own penalties (disciplinary action, loss of network connectivity) on anyone who is found to be using CityU facilities or campus network for such purposes.

Moreover, organisations hired by the copyright owners are aggressively searching for copyright violators on the Internet and will take independent legal action against such violators. Peer-to-peer file sharing activity using the campus network is easily subject to their scrutiny as long as they remain as one of the participants. Many past legal actions by these organisations have resulted in successful imposition of substantial monetary penalties on the violators.

Please be aware that the target of these actions is not only the individuals engaged in the violations but also the University if it has not shown its diligence in curbing these violations being carried out on its computers or network. As an Internet service provider, the University has no way to prevent but to be obliged without delay to cooperate fully with any law enforcement agency requesting the names of individuals who use computers to share copyrighted materials illegally.

As such, users who use their accounts on the University facilities for such activity inevitably expose both themselves and potentially the University to legal action. Therefore, to protect yourself and the University, make sure you will not engage in illegal storing or sharing of copyrighted materials.

Please Tell Us If You No Longer Need a Booked CSC Teaching Studio

The teaching studios in the Computing Services Centre (CSC) have always been under great demands. For better uses of University resources and for benefits of those staff and students who may still wait for these rooms, as soon as you know that you no longer need the booked CSC teaching studio, please kindly cancel your booking through the CSC Teaching Studio Booking System or through our staff at the Service Counter in the CSC Terminal Areas at least one day in advance. If you have any enquiries, please contact the CSC Service Counter.

Please Consult Your Supervisor before Delivering Sensitive Information

In order to ensure the consistency in delivery of sensitive information and to avoid misunderstanding or embarrassment, colleagues are reminded to consult your supervisor before sending any information or forwarding any email from others in part or in whole to users that may be sensitive in nature. If you are not sure whether the information requested is sensitive, it is always prudent to check it with your supervisor before action.

CKC Chinese Input Systemis Available at CityU
By Matthew Hung

When we talk about Chinese input method in the subject of "Chinese Computing", you will immediately relate this to the "Chang Jie ", "Pinyin ", "Quick " etc. input methods. Then, you might also have experienced the hardship when you start to learn using the keyboard and memorize keystroke combinations and complicated input rules. You may have an impression that most of the Chinese input methods are difficult to learn or use through keyboard inputting methods. Some may even prefer to use pen input method. In fact, each Chinese input method is designed for different targeted users. For example, pen input method is easy to learn but relatively slow in input speed, it is good for general users; whereas "Chang Jie" is difficult to learn but the input speed is fast for experienced users. Therefore, it is good for frequent users. And the CKC Chinese Input System[Ref: 1] is designed to provide the best of both the learning curve and input speed.

CKC Chinese Input Systemis developed by [Ref: 2] and . The software can run on Microsoft Chinese Windows 95/98/ME/NT/2000/XP environment. In particular, it can also run on the English Windows XP environment we currently supported in campus. We have made this input method generally available in both the CityU staff and student network.

The software plugs well into the XP environment and supports the Hong Kong Supplementary Character Set (HKSCS - 4702 Hong Kong characters) [Ref: 3]. After successful installation, an option of will be added to the available input methods under "Chinese (Taiwan)" as shown below:

When users have selected the as the current input method, the system will display an input method task bar:


This input method is a keyboard input one. Actually, it only uses a maximum of 4 digits ("0" - "9") to represent a character. Strokesof all Chinese characters are classified into 10 groups, each represented by a digit. For example, "0" represents "" and "1" for "" ...etc. Chinese characters can then be input by the combination of these digits. Users can use the formula below to remember this stroke representation:



In case users forget one or two digit mapping, they can always click on the"" button in the input method task bar to activate the hint as display below:


The main principle of composing "CKC" codeto form a single Chinese character is:

  • Take the stroke of the upper left hand corner of the character as the first code
  • Take the stroke of the upper right hand corner of the character as the second code
  • Take the stroke of the lower left hand corner of the character as the third code
  • Take the stroke of the lower right hand corner of the character as the fourth code

e.g


In the above example, the first code of the character "" is 4, second code 3, third code 1 and fourth code 7. Therefore the "CKC"code of "" is 4317. However, the "CKC"code of some Chinese characters may not necessarily be a 4 digit code.

e.g

In this example, the "CKC" code of "" is 320.

Users have to use the numeric pad to key in the code and complete the input with a space. If more than one character can be represented by the same "CKC" code, the system will show all the characters for selection. Users can use numeric pad "0"-"9" for selection, or use "PageUp" / "PageDown" to turn to the other pages.

One of the strengths of CKC Chinese Input System is that it caters for the input of phrases to increase input speed. The system has predefined more than 250,000 common Chinese phrases, such as ""

The principles of composing "CKC" code for Chinese phrases are:

  • For 2-character phrase
    • To get the first 3 digits at most of each character. It forms the 3+3 coding principle. The minimum number of digit of this phrase is 2 and the maximum 6.
    • E.g. the "CKC"code of "" is 4804, and "" is 300. However, the code of the phrase "" is 480300.
  • For 3-character phrase
    • To get first 2 digits at most of each character. It forms the 2+2+2 coding principle. The minimum number of digit of this phrase is 3 and the maximum 6.
    • E.g. the "CKC"code of "" is 5100, "" is 7770 and "" is 4297. The code of the phrase "" becomes 517742.

  • For 4-character phrase
    • To get the first 2 digits at most of the first character, then the first digit of the second and third character. Finally, the first 2 digits at most of the fourth character. It forms the 2+1+1+2 coding principle. The minimum number of digit of this phrase is 4 and the maximum 6.
    • E.g. the "CKC"code of "" is 868, "" is 3367, "" is 800 and "" is 100. The code for the phrase "" becomes 863810.

  • For Multi-character phrase
    • To get the first 2 digits at most of the first character, then the first digit of the second, third, fourth and fifth character, and the rest of characters are ignored. It forms 2+1+1+1+1 coding principle. The minimum number of digit of this phrase is 5 and the maximum 6.
    • E.g. the "CKC"code of "" is 06, "" is 3417, "" is 0450, "" is 6200, "" is 0120, "" is 1814 and "" is 7171. The code of the phrase "" is then 063060.

From the above illustration, you can see that if users input "" one by one character, they have to type in 06 3417 0450 6200 0120 1814 7171 with selections and a number of strokes for space bar in between. Now, they just need to key in 063060 and then they can select the right phrase. Beside providing a large number of pre-defined phrases, CKC Chinese Input System also allows users to define their own phrases, such as "". On top of that, there are many other features in CKC Chinese Input System to help users to input Chinese characters more easily and quickly, such as wild card key and associated key .

The purpose of this article is to introduce CKC Chinese Input System. Other features of this input method are left for users to explore.
