The objective of this research is to compare the teacher education system in countries that have reformed, or are in the process of reforming, their informatics education by reflecting ongoing social changes and developments in IT. The teacher education systems in Finland, Germany, Japan, the UK and US were compared. As a result of the study it was found that (1) the results did not differ according to the teacher education institution, (2) there was a focus on a minor subject, and (3) there were various routes for teacher training. The systems for special graduate schools were found to be developed, probation period after graduation was more than one year, and license renewal systems were being enforced. Based on these results, it was proposed that (1) more teachers be recruited to attend graduate schools and (2) that software training be given to all teachers as a minor. Finally, a license renewal system for revaluating teachers' qualifications was also proposed. This research is meaningful in that it compared the teacher training system in Korea with five major developed countries.

In this paper, we design an e-Learning system for the Driver's License Teste studying through the Internet. The proposed system make users to be arrived at the goal for the license in a shorter time by offering learning contents and items according to the item-responses made by the users based on the Item Response Theory. Moreover we design the scheme to give the optimum items and the most necessary content to the user during the learning procedure in the form of concept-based objects. All the items in the problem bank DB maintain their difficulties, discriminations, and guessing parameters as is the case of 3-parameter logistic model. In addition user profile DB stores users' status informations, item responses, and ability parameters. Using these structures and combining agents, we can offer the optimum learning process or dynamic personalized studying structure to the user. We can construct interface agent and content selection and feedback agent with the DB's described above. User can study without any awareness of system operations or personal fitting scheme.

Illegal software use have been abroad through online (internet) and offline (CD, DVD, USB, etc.). It infringes intellectual property rights and weakens the will to software development. Also, it generates the software errors and virus intrusion in PC. It hinders national software industry and induces the personal and national trade friction. Many group (company, office, organization, institution, etc.) have been realized the prohibition of illegal software use. But, it is too hard to monitor and control illegal software use. In this paper, we propose a method of software management in a group. A software module of client agency is installed in all PC of the group. A main server of the software management controls the all of the PC through the communication. The server blocks the install of illegal software, permits the install / use of honest goods software, monitors the license (term, amount) in all the PC. The system prevents errors of illegal software use, all cuts the virus intrude through the illegal software, improves the performance of PC relatively.

This paper describes our design of a contents distribution framework that supports transparent distribution of digital contents on the Internet as well as copyright protection of participants in the contents distribution value chain. Copyright protection must ensure that participants in the distribution channel get the royalties due to them and that purchasers use the contents according to usage rules. It must also prevent illegal draining of digital contents. To design a contents distribution framework satisfying the above requirements, we first present four digital contents distribution models. On the basis of the suggested distribution models, we designed a contract system for distribution of royalties among participants in the contents distribution channel, a license mechanism for enforcement of contents usage to purchasers, and both a packaging mechanism and a secure client system for prevention of illegal draining of digital contents.

Regarding the improvement of the dental specialist program, two related issues were reviewed extensively: (a) bill amending portions of the Medical Service Act as proposed by national assemblywomen Choi Yeong-hui (Democratic Party) and Chung Mi-gyeong (Grand National Party), and; (b) Plans to supplement the submitted bill. Although the existing bill's prospects in the assembly are unclear at this point, both the existing and planned supplementary bills zero in on two points: (a) specialists must focus on providing care only in their respective expertise, and; (b) a distinction between the roles played by the primary, secondary, and tertiary medical institutions must be made to help establish clearly the country's overall health care system. In addition, proposals were made for medical license renewal among specialists so that professionals can offer better health care to customers.

There are big differences in dental education system between South Korea and North Korea. In North Korea, there is no college of dentistry and official license system and thus, dentists can treat a patient right after graduation from medical school. There are also positions such as paradentists capable of providing dental treatments, whereas such positions do not exist in South Korea. In this regards, in order to get ready for the United Korea, we need to establish a system designed to complement the differences in dentistry education and license system between South and North Korea. Such system would help to minimize the social cost in relation to the unification in near future.

디지털 기술의 발전으로 인해 원본과 동일한 품질을 가지는 디지털 콘텐츠의 무한한 복제가 가능할 뿐만 아니라 인터넷을 통해 전 세계 어디라도 전파될 수 있다. 이러한 디지털 콘텐츠의 불법복제에 따른 문제를 해결해 줄 수 있는 것이 바로 DRM(Digital Rights Management)이다. 하지만 현재의 DRM은 콘텐츠를 구매하여 License를 받은 최초의 디바이스에서만 사용이 가능하도록 설계 되어 있다. 이러한 방식은 콘텐츠를 구매한 사용자의 권리를 제한하는 것이다. 본 논문에서는 Home Network와 같은 특정 Domain영역 안에서만 콘텐츠의 사용이 가능한 DRM 시스템을 제안한다.

The intellectual property system was very important to the past industrial society. It is so important to the 21C information age. It is a leading role to developing these information society. Not only the digital content control but the technology of software source code for the intellectual property is so much mean to international competition. On occurring disputation property, we have to prove the fact, there is a problem to discriminate the original source code. In this paper, we make a study of the digital licence prototype for discriminate the original source code. Reserved words of software source code by parsing express to XML file that have hierarchical structure. Then, we can express architecture of software source code by tree structure form instead of complex source code. And we make a study of the indexing and searching to search digital license.

As the logistic environment of digital contents is rapidly changing, the protection of the digital rights for digital content has been recognized as one of critical issues. Digital Right Management(DRM) has taken much interest Internet Service Provider(ISP), authors and publishers of digital content as an interested approach to create a trusted environment for access and use of digital resources. This paper propose an interested digital rights protection scheme using license agent to address problems facing contemporary DRM approached : static digital rights management, and limited application to on-line environment. We introduce a dynamic mission control technology to realize dynamic digital rights management. And we incorporate license agent to on- and off-line monitoring and tracking. The proposed system prevent illegal access and use by using PBD security method real time action monitoring for user, data security for itself.
