DNS(Domain Name Service)는 인터넷 호스트의 주소를 제공하는 서비스로써 기존의 시스템은 영어 알파벳 이외의 다른 언어들로 구성된 도메인 네임(Domain Name)은 처리하지 못한다. 최근, 인터넷의 국제화에 따른 다국어 도메인의 필요성이 점차 증대됨에 따라 이러한 문제점을 해결하고 다국어 도메인 이름을 처리할 수 있는 새로운 DNS 프로토콜인 mlDNS(Multilingual Domain Name Service)를 제안한다. 기존의 DNS와의 호환성 및 상호 운용성을 보장하고 특정 언어에 종속되지 않는 시스템을 디자인하기 위해 mlDNS에서는 Unicode 문자 집합을 기반으로 모든 DNS 질의를 UTF-8 인코딩 방식으로 처리하고 이러한 새로운 mlDNS 질의와 기존의 DNS 질의를 구분하기 위해 DNS 질의 헤더에 'IN'이라는 새로운 비트 영역을 지정하여 사용한다.

Complement fragment iC3b serves as a major opsonin for facilitating phagocytosis via its interaction with complement receptors CR3 and CR4, also known by their leukocyte integrin family names, αMβ2 and αXβ2, respectively. Although there is general agreement that iC3b binds to the αM and αX I-domains of the respective β2-integrins, much less is known regarding the regions of iC3b contributing to the αX I-domain binding. In this study, using recombinant αX I-domain, as well as recombinant fragments of iC3b as candidate binding partners, we have identified two distinct binding moieties of iC3b for the αX I-domain. They are the C3 convertase-generated N-terminal segment of the C3b α'-chain (α'NT) and the factor I cleavage-generated N-terminal segment in the CUBf region of α-chain. Additionally, we have found that the CUBf segment is a novel binding moiety of iC3b for the αM I-domain. The CUBf segment shows about a 2-fold higher binding activity than the α'NT for αX I-domain. We also have shown the involvement of crucial acidic residues on the iC3b side of the interface and basic residues on the I-domain side.

Recent malicious attempts in Cyber space are intended to emerge national threats such as Suxnet as well as to get financial benefits through a large pool of comprised botnets. The evolved botnets use the Domain Name System(DNS) to communicate with the C&C server and zombies. DNS is one of the core and most important components of the Internet and DNS traffic are continually increased by the popular wireless Internet service. On the other hand, domain names are popular for malicious use. This paper studies on DNS-based cyber threats domain detection by data classification based on supervised learning. Furthermore, the developed cyber threats domain detection system using DNS traffic analysis provides collection, analysis, and normal/abnormal domain classification of huge amounts of DNS data.

Generally, the Internet Address Resources Act is intended to protect the public from acts of Internet "cybersquatting", a term used to describe the bad faith, abusive registration of Internet domain names. In determining whether a person has a bad faith intent, a court may consider factors such as, (1) the trademark or other intellectual property rights of the person, if any, in the domain name, (2) the extent to which the domain name consists of the legal name of the person or a name that is otherwise commonly used to identify that person, (3) the person's prior use, if any, of the domain name in connection with the bona fide offering of any goods or services, (4) the person's bona fide noncommercial or fair use of the mark in a site accessible under the domain name, (5) the person's intent to divert consumers from the mark owner's online location to a site accessible under the domain name that could harm the goodwill represented by the mark, either for commercial gain or with the intent to tarnish or disparage the mark, by creating a likelihood of confusion as to the source, sponsorship, affiliation, or endorsement of the site, (6) the person's offer to transfer, sell, or otherwise assign the domain name to the mark owner or any third party for financial gain without having used, or having an intent to use, the domain name in the bona fide offering of any goods or services, or the person's prior conduct indicating a pattern of such conduct.

네트워크의 보안문제는 트래픽의 증가요인의 하나로 작용한다. 본 논문에서 키 분배와 인증 문제를 해결하면서 트래픽을 증가를 억제할 수 있는 키 관리 시스템을 제안하였다. 인터넷의 도메인 방식을 이용한 제안된 키 관리 시스템은, 기존의 키 관리 시스템인 중앙 집중형 키 관리 및 분산형 키 관리 시스템의 문제점을 개선할 수 있을 뿐 아니라 이들 시스템과 혼용하여 사용할 수 있을 것으로 판단된다. 키의 인증기관은 각각의 도메인에 존재하는 키 분배 센터 내에 분산시켜 상위 도메인으로부터 인증을 받게 되므로 인증 수준을 다중으로 할 수 있으며 단일화 된 인증기관의 위험을 해결할 수 있다.

본 연구에서는 인터넷상에 존재하는 웹 사이트를 새로운 도메인 네임으로 연결시켜주는 URL forwarding 서버를 설계 및 구현하였다. URL forwarding 서버는 수많은 인터넷 사용자들의 웹 사이트를 간단하고 다양한 형태의 URL로 매핑 시켜준다. URL forwarding 서버는 HTTP 프로토콜에서 redirection 응답코드를 기반으로 구현되었으며 Linux 시스템에서 실험을 하였다. 본 논문에서는 HTTP와 forwarding 서버를 서로 비교 분석하여 고찰해보고 구현된 forwarding 서버의 동작에 대해서 알아본다.

Now in Korea, the 7th curriculum reform is underway. The main difference of the seventh curriculum compared with former curricula is that it puts much emphasis on individual difference. It is a "differentiated" curriculum. The basic directions of the 7th mathematics curriculum are as follows: 1. Offer various mathematical subjects for "Selective Educational Period" (Grades 11 and 12). 2. 30% reduction of mathematical contents. 3. The reconciliation of domain names of school mathematics. 4. The use of computers and calculators in mathematics classrooms.

An Internet user obtains an IP address from DNS to access the host. But, Korean users must use English word order Domain that is not convenient for them. All existing systems have the reverse of the Korean word order and that is the obstacle to the spreading of Internet. So, the necessity of a Korean name system that well suited for Korean Internet user is increasing. In order to operate the proposed Korean Domain System with existing Domain Name Systems, we build a Korean to English transformation rule and Korean Domain Name composition rule. Also, we designed a STHOP for Korean word order processing. In a STROP, a SLDF transform a Korean SLD into English SLD, and a NFDNG makes this as an English word order. By using Korean Domain Name System proposed here, users could understand the embedded meaning of Domain Name with ease, and reluctance of Domain registration caused by similarity of organization names would be solved, Consequently. it could devote to the popularization of the Internet.

Internet Corporation for Assigned Names and Numbers (ICANN) is the body which manages the allocation and registration of global Internet IP addresses and domain names. As a gesture to overcome the dependency on the U.S. government, ICANN and the U.S. Department of Commerce jointly made the Affirmation of Commitment in which they submitted the workings of ICANN to the supervision of a council of Internet experts. Accountability and Transparency Review Team (ATRT) is one of four teams created for this purpose. In December 2010, ATRT made 27 recommendations, which were subsequently approved by the ICANN Board. These reform efforts of ICANN provide significant implications for the future of Korean Internet governance. Korea should enhance the compatibility of its domestic decision making process related to Internet addresses with the private sector driven, bottom-up process of global Internet governance. In order to increase the involvement of private sector and civil society, it is recommended for Korea to formalize the mechanism for bottom-up process. Insertion of a new provision concerning a bottom-up process into the Internet Addresses Act should be considered.

Recently, the Internet Corporation for Assigned Names and Numbers (ICANN) announced the expansion of the number of generic top-level domains (gTLDs) beyond the current 22 gTLDs, and the gTLD Applicant Guidebook for ICANN's new gTLD program is now under consideration for approval. ICANN also introduces a "Trademark Clearinghouse" and the "Uniform Rapid Suspension (URS)" procedure to protect trademarks and expedite dispute resolution and save costs. The Trademark Clearinghouse is a central repository for information to be authenticated, stored and disseminated, pertaining to the rights of the trademark holders. Trademark holders would voluntarily provide data of their trademarks from all over the world, and it would assist a trademark watch service provided by the new gTLD registry for trademark holders and potential domain name registrants. The URS is a part of the new gTLD dispute resolution mechanisms created by ICANN to resolve cybersquatting disputes. A complainant in a URS proceeding must establish three elements that are very similar to the existing UDRP to succeed, but supposedly more expedited and cost efficient. Since the URS provides that it only protects court validated and registered trademarks, it is not clear whether unregistered marks used in commerce are protected under the URS. The URS escalates the complainant's burden of proof from a preponderance of evidence standard under the UDRP to a clear and convincing evidence standard. The notices to a respondent shall be sufficient if the URS Provider sends the notice of Complaint to the addresses listed in the Whois contact information. As registrants who wish to conceal their true identity often subscribe to the privacy/proxy service and the complainant's high rate of success in the UDRP proceeding is relevant to the respondents' default rate, the URS's simple notice requirement would deprive respondents of a fair opportunity to assert their rights over the disputed domain names.
