The Korea Internet AS-level topology was constructed using three data sources: Border Gateway Protocol (BGP) trace collector, Internet Routing Registry (IRR), and Internet Exchange Point (IXP). It has 685 nodes and 1,428 links. The Korea Internet AS-level topology is a small regional subgraph of the massive global one. We investigate how well the Korea Internet preserves the topological characteristics of the global one or how different they are. We carefully select several topology metrics that can analyze the characteristics of the Korea Internet AS-level topology. We also investigate how well Internet topology generators can represent the characteristics of the Korea Internet AS-level topology.

The explosive growth in wireless networks and Internet services has created considerable demand for mobile Internet services based on the mobile phone. Mobile Internet has become the new business model in telecommunication market, therefore the open network policy for mobile Internet has been formulated and implemented by the government in Korea. In spite of the open network policy for mobile Internet, there has been no systematic analysis of the various interconnection issues, including pricing, in mobile Internet network. This paper aims to suggest the interconnection pricing methods for mobile Internet network by reviewing the current pricing models for various communications services, and adapting them to mobile Internet communications circumstances. Results of this paper can be used as a guideline for government policy directions and management decision making after the introduction of the open network policy for mobile Internet.

Recently, Internet Telephony has become increasingly popular in telecommunication industry. However, previous research on Internet Telephony has focused on analyzing specific Internet Telephonysolutions, identifyingthe Internet Telephony movement itself. The research on prediction models about Internet Telephony adoption has been minimal. The main propose of this study is to develop models for predicting transition intention from using traditional telephones to using Internet Telephony. To do so, this study uses data mining methods to analyze demands in the IT communications market and to provide management strategies for Internet telephony providers. Especially this study uses discriminant analysis, logistic regression, classification tree, and neural nets to develop those prediction models toward Internet Telephony adoption. The models are compared with each other and a superior model is chosen.

본 연구는 한국과 일본에서 나타나는 인터넷 이용행태의 기본적인 특성과 전반적인 인식이 온라인에서의 관계망의 형성과 유지에 어떤 영향을 주고 받는지를 구체적으로 살펴보았다. 이를 위해 한국과 일본의 이용자들의 온라인 관계망의 현황과 개인적 성향, 인터넷 이용패턴, 그리고 인터넷에 대한 인식 등을 설문조사를 통해 알아보았다. 연구결과를 요약하면, 온라인 관계망의 크기와 활용에 있어서 한국의 이용자들이 보다 적극적인 것으로 나타났으며, 양국 모두 자주 만나기 어려운 사적인 관계의 대상들과 관계하는 비율이 높은 것을 알 수 있었다. 또한 한국의 이용자들은 개인적 성향이나 인터넷 관련 행태 및 인식이 전반적으로 만남의 방식에 영향을 미치지 않았던 데 비해 일본의 이용자들은 관계지향적인 인터넷 이용 패턴과 인터넷의 유용성에 대한 인식이 온라인에서의 접촉 양상에 영향을 미치는 것으로 나타났다. 온라인 관계망의 크기와 관련하여 양국 모두에 공통적으로 나타난 것은 인터넷을 정보지향적으로 이용할수록 등록된 대화상대가 증가한다는 점이었다. 이는 인터넷에서의 관계형성에 있어 약한 유대에 기반한 관계가 효율적이고, 이러한 관계를 통해 얻을 수 있는 혜택이 정보적 혜택이라는 기존의 이론과 잘 부합하는 결과라고 할 것이다. 아울러 일본의 경우 온라인에서의 관계형성 전반에 있어 온라인 공간에 대한 위험인식 정도, 즉 신뢰의 여부가 크게 영향을 미치는 것으로 분석되었다.

삶의 전 영역에 걸쳐서 빠르게 확산되고 있는 인터넷은 효율성과 생산성, 오락성의 편익을 제공하는 반면, 익명성과 비대면성의 매체 특성으로 인해 이를 악용한 인터넷 윤리의식이 심각한 사회문제가 되고 있다. 이에 인터넷으로 인한 부작용을 예방하고 보다 인간 중심의 인터넷 문화를 창달하기 위해 인터넷 윤리교육의 중요성이 부각되고 있다. 본 논문에서는 대학 신입생들을 대상으로 인터넷 윤리의식에 대한 실태를 조사하여 분석한 결과를 바탕으로 바람직한 인터넷 윤리교육 방안을 제안하였다. 인터넷 윤리의식 실태를 개인정보 침해, 지적 재산권 침해, 유해정보, 인터넷 대화문화, 사이버 폭력, 인터넷 중독, 인터넷 사기 등으로 분류하고 설문조사를 실시하여 분석하였다. 그리고 인터넷 윤리의식의 분석 결과를 기초로 대학생들에게 바람직한 인터넷 윤리교육 방안을 제안하였다. 제안한 인터넷 윤리교육 방안을 적용하여 인터넷 윤리 교육을 실시하고, 교육의 효과를 측정하였다. 측정한 교육의 효과를 통계적으로 검증한 결과, 제안한 인터넷 윤리교육 방안이 대학생들의 인터넷 윤리의식을 개선시키는데 효과가 있음이 확인되었다.
