This paper discusses the types and functions of English subordinate clauses, whether English subordinate clauses (SC) are headed by a Complementizer (CP) or headed by a lexical (but not functional) Preposition (PP). Furthermore, unlike the standard classification, the current paper provides a finer-grained analysis and classification of English SCs. The traditional or prescriptive view on the functions of English SCs includes Noun SC such as complement clauses, Adjectival SC including relative clauses, and Adverbial SCs that cover a garden variety of subordinators. Added to the existing classification of subordination in English is what I notate as Verbless subordinate clause (V-less SC). Of these 4 different types of subordinate clauses with different functions, properties, and distributions, Subjectless Verbless subordinate clause is further divided into Smallest small clause (SSC) which accounts for English subordination mechanism more uniformly and consistently with respect to their clausal architecture, especially when the subordinate clause is neither PP nor CP.

As the use of smart devices has become popular, the number of smart devices connected to network has increased and the amount of traffic from them has grown rapidly. The management of mobile traffic and IP address for smart devices in an enterprise network is crucial problem for efficient operation of network. The information about connection type of a terminal host to the network will be very useful for stable and efficient management of an enterprise network. Also, this information might be used to identify NAT device. In this paper, we propose a methodology to identify the connection type of a terminal host using RTT (Round-Trip-Time) value extracted from captured packets. We prove the feasibility of our proposed method in a target campus network.

오늘날 인터넷기술의 급속한 발전으로 인하여 IP Phone서비스의 활성화가 기대되며 이러한 IP Phone 서비스시장의 확대는 기존 PSTN망에 의한 전화서비스시장에 지대한 영향을 미친다. 따라서 IP Phone 서비스시장에 있어서도 상호접속제도 도입의 필요성이 점증되고 있다. 이에 따라 본고에서는 IP Phone 서비스의 상호접속유형을 살펴보고 관련된 사업자간 정산문제에 대한 해결방안을 제시하고 있다.

The issues on the interconnection of telecommunications network are recently prevailed in the IT industry. In this study, we classify the network interconnection system into two categories: two way-same price model and two way-different price model. The purpose of this paper is to analyze economic characteristics of optimal settlement system according to each model. One of the most important policy implications we derive through this study is that symmetry between enterprises is required for policy maker or regulatory agency to set an efficient settlement system under two way-same price model, but that symmetry is not necessarily required under two way-sane price model.

공중전화망을 통해 인터넷에 접속할 수 있는 가장 흔한 방법은 다이얼 접속이다. 다이얼 접속방법에는 접속하는 사업자 수에 따라 크게 두 가지의 접속방법이 있다. 접속을 제공하는 전화망 사업자의 수가 하나인 경우는 보통의 인터넷 접속의 형태이며 전화망 사업자가 두 개인 경우는 인터넷 사업자가 직접접속하고 있는 사업자와 인터넷 이용자가 속해 있는 사업자가 서로 다르다는 것이 특징이다. 즉 인터넷 이용자는 착신측 사업자망을 경유하여 인터넷 접속서비스를 제공받는다는 것이다. 현재 유럽에서는 그중 인터넷 접속 시 복수사업자를 경유하여 접속하는 방법이 가장 특징적이다. 본 고에서는 접속사업자 수 및 접속형태에 따른 접속료 정산방안 모델과 유럽의 사례들과 함께 시사점을 살펴보고 있다.

MVNOs(Mobile Virtual Network Operator) provide mobile services without the own spectrum license and they lease the wireless networks from mobile network operators. They provide more covered service simple resellers have served. Most of MVNO provided in Korea have facilities related to subscribers not lines and switches. Therefore interconnection between MVNO and the other operators is performed by mother mobile operators. Recently following to reform the Business Act of Telecommunications, MVNOs are allowed to interconnect directly to others and there are concerning problems to this. This paper reviewed the status of MVNO regulations for major countries and draw from implications for establishing the MVNO regulations in Korea.

Today the various types of communication and application service are provided by the development of Internet and IP technologies. It is expected to be extended the service domain of two networks through the interconnecting P2PSIP overlay which is highlighted as an important technologies for Internet based services and IMS(IP Multimedia Subsystem) which is the new architecture adopted in the evolution of NGN. Therefore, this paper explains the possible methods of the service expansion with interconnecting P2PSIP overlay and IMS network. Specially this paper suggests the interconnection architectures of P2PSIP overlay and IMS network as subscriber's types and analyzes the traffic analysis model and session set up delay characteristics by simulation model. As a results, this paper shows that the interconnection architecture using gateway AS(Application Server) is the excellent method to interconnect the IMS in case of P2PSIP overlay only subscriber, and that interconnection architecture using I-CSCF is good method to interconnect the IMS in case of P2PSIP overlay and IMS subscriber.

번역을 지원하는 도구로 자동 번역 시스템을 효율적으로 활용하기 위해 중요한 것은 자동 번역에 적합하도록 원문을 작성하거나 이미 작성된 원문에 대한 전처리 작업을 하는 것이다. 본 연구의 궁극적인 목표는 제품 설명서 작성자가 통제언어 체커를 통해 통제언어 규칙들을 적용하여 원문을 작성하도록 하는 것이다. 본 논문은 그 중간 단계로써 제품 설명서에 나타나는 문제 사항이 번역 품질에 어떠한 영향을 미치는지 밝혀내는 것을 목적으로 한다. 연구 대상은 제품 설명서에서 자동 번역의 성능을 저해시키는 요소 중 중의적 명사 수식 구문이다. 이러한 명사 수식 구문들은 분석 단계에서 구조적인 모호성을 초래하여 한국어 분석의 정확도를 떨어뜨리기 때문에 결과적으로 번역 품질을 악화시킬 수 있다. 이를 검증하기 위해 우선 제품 설명서 데이터를 분석하여 자동 번역 결과에 부정적인 영향을 미치는 명사 수식 구문을 다음과 같이 4가지로 유형화 하였다. (유형 1) 관형격 명사구 + 명사 병렬 접속, (유형 2) 동사의 관형형이 수식하는 명사구 + 명사 병렬 접속, (유형 3) 관형격 조사 '의' 중복, (유형 4) 병렬 접속어를 잘못 쓴 경우, 각각의 유형에 대해서 한국어 분석 단계에서 발생할 수 있는 문제에 대해 설명하였으며, 문제 사항에 대해 통제언어 규칙을 제시하였다. 통제언어 규칙에 따라 중의적 명사 수식 구문을 수정한 결과, 한국어 원문의 번역결과보다 한국어 수정문의 번역결과가 작성자의 의도를 더 잘 나타낸다는 것을 확인할 수 있었다.
