현행 민영화정책이 공기업의 효율성제고를 최우선 목표로 설정한 것은 타당한 선택이었음에도 불구하고, 경제력집중 심화에 대한 우려와 주식시장의 제약 등을 이유로 민영화정책은 그 추진실적이 부진하고 향후 지속 여부가 불투명한 것이 현실이다. 본(本) 논문(論文)은 우리나라 공기업민영화를 둘러싼 논쟁의 핵심인 경제력집중(經齊力集中), 경쟁도입(競爭導入), 주식시장여건(株式市場與件) 등이 공기업민영화와 관련하여 어떻게 이해되어야 할 것이며, 바람직한 정책대응(政策對應)은 무엇인지를 논의하고 있다. 재산권이론(財産權理論)을 동원하여 주인(主人) 있는 경영(經營)의 의미를 재해석할 때, 기업지배(企業支配) 통제구조(統制構造)의 정착이 요원한 우리 현실에서 민영화가 기업효율을 제고하려면 민간대주주(民間大株主)의 지배(支配)를 인정하는 방식이 최선책(最善策)이며, 소유가 분산되고 전문경영체제(專門經營體制)를 도입하는 민영화방식은 지배구조(支配構造)의 실패가능성(失敗可能性) 때문에 차선책(次善策)이라고 평가된다. 그러나 효율성 차원의 최선책은 경제력집중이라는 국민경제적 비용을 초래하므로, 정부로서는 경제력 집중이라는 비용(費用)과 효율성이라는 편익(便益)을 조화시키는 방안을 모색할 수밖에 없다. 이 경우 정부가 고려할 보완책(補完策)으로는 감자후(減資後) 민영화(民營化)와 분할민영화(分割民營化)가 있다. 한편 자연독점의 특성이 뚜렷한 일부 네트워크사업분야를 제외하면, 민영화시 경쟁도입(競爭導入)은 기업효율성과 국민경제의 배분효율성을 제고하므로 정부로서는 당연한 선택일 것이다. 경쟁은 공기업의 인수자격규제에 있어서도 새로운 기준을 제시하는데, 민영화를 정부(政府)와 민간(民間)사이의 M&A로 이해하고 경쟁제한적(競爭制限的) 기업결합(企業結合)을 규제하는 공정거래법(公正去來法)의 정신(精神)이 인수자격규제기준이 되어야 하며, 업종전문화(業種專門化) 발상(發想)에 근거한 인수자격규제는 득보(得)다 실(失)이 클 것이다. 아직도 자생적 성장기반이 취약한 주식시장의 제약에 따라 민영화일정의 탄력적인 조정은 불가피하지만, 정부는 상장(上場)의 필요성(必要性)을 재검토하고, 매각(賣却)의 우선순위(優先順位)를 조정하며, 무엇보다도 양질(良質)의 주식(柱式) 공급(供給)이 수요(需要)를 창출하는 메커니즘을 개발해야한다. 이와 함께 본(本) 논문(論文)은 현행 추진체계(推進體系)에 내재된 민영화의 지연가능성이 심각한 문제임을 지적하였고, 대규모 공기업의 민영화가 대기업(大企業)의 새로운 전형(典型)을 창출하여 한국자본주의(韓國資本主義)의 건전한 발전을 앞당기는 역사적 기회라는 점을 강조하고 있다. 마지막으로 재벌인수가 가능한 경우와 규제되어야 할 각각의 경우에 대하여 민영화정책(民營化政策)의 '체크리스트'를 제시하고 있다.

The Internet succeeded because of the end-to-end principle which allowed anyone to add functionality to the network. However, as the internet is increasingly becoming the platform for smart IT applications such as VoIP, IPTV, Cloud Computing and Smart Phone, networks are now under increasing strain of traffic congestion and the absence of quality of service insurances. To date, the debate over internet rules has focused on network neutrality rather than network efficiency. This article emphasizes the well-functioning role of market mechanism for the efficient use and further development of the network. To maximize the value of the network, this article proposes a differential treatment to packets based on customer types, and a two-part tariff pricing rule to secure funding to expand and upgrade networks.

While evolving information-oriented society provides a lot of benefits to the human life, new types of threats have been increasing. Particularly, cyber terrorism, happen on the network that is composed of a computer system and information communication network, and the mean and scale of damage has reached a serious level. In other words, it is hard to locate cyber terror since it occurs in the virtual space, not in the real world, so identifying "Who is attacking?" (Non-visibility, non-formulas), or "Where the attack takes place?" (trans-nation) are hard. Hackers, individuals or even a small group of people, who carried out the cyber terror are posing new threats that could intimidate national security and the pace and magnitude of threats keep evolving. Scale and capability of North Korea's cyber terrorism are assessed as world-class level. Recently, North Korea is focusing on strengthen their cyber terrorism force. So improving a response system for cyber terror is a key necessity as North Korea's has emerged as a direct threat to South Korean security. Therefore, Korea has to redeem both legal and institutional systems immediately to perform as a unified control tower for preemptive response to cyber terrors arise from North Korea and neighboring countries.

The public-private partnership concept can encompass a broad range of cooperative relations and a broad variety of programmes in terns of size, objectives and design. This paper aims to analyze the components of public-private partnership mechanisms in the context of science and technology innovation policy. The research methodologies are based on semi-structured interviews with policy makers in four countries with six PPP programme : the France, the Netherlands, the Australia and Austria. It also attempts to understanding of the components that explain the increase of collaboration between national innovation system and PPPs. The taxonomy and essential components of PPPs were identified : mission-oriented PP/Ps, market-Oriented PP/Ps, cluster-oriented PP/Ps, and ISRs-Oriented PP/Ps. The taxonomy of regulatory regime can be a reference point for identifying the relative status of Korea's PPPs.

Currently, urban areas face congestion problems that diminish personal mobility and freight-transport productivity. An increasing number of experts suggest that separating freight traffic from passenger traffic makes sense in terms of economics, the environment, and safety. Some experts suggest that tube transportation is the solution. The objective of this paper is to evaluate the potential benefits and limitations of tube transportation system as a viable mode of transport that can alleviate congestion on roadways. Specifically, this research employs theoretical and practical method identifying, evaluating, and selecting appropriate freight pipeline systems; evaluating the technical and economic feasibility of tube transportation; and estimating environmental, energy, and safety benefits.

The traditional four-step demand model has limits in that it cannot reasonably reflect the logistic characteristics of freight transportation system. This is likely to cause problems when estimating the effects of logistics facilities. In order to enhance the reliability and availability of the freight demand estimation procedure it is needed to develop freight demand model which takes into account the logistic characteristics of firms. In the late 1990s, a number of researches on freight demand model considering logistics behaviors began in Europe while a few studies in the area have been conducted recently in Korea. This paper reviews recent advances of the freight model developments in the context of logistic behavior consideration. The main topics include 1) commodity classification, 2) P/C(Production- Consumption) estimation, 3) logistics network representation, 4) logistics chain model, and 5) commodity flow survey. In addition, this paper proposes future direction of the freight demand models with respect to the consideration of logistics characteristics.

One of the recent important issues in IT fields is the convergence. It had been simply focused on functional convergence of technologyies. However the convergence in terms of businesses or services also has been made in recent years. The convergence between broadcasting and telecommunication industries can be possible because the e-transformation of broadcasting industry based on digital technology such as multimedia and multi-channel, can be combined with the high speed telecommunication network. It is giving a birth of various convergence services such as IPTV. IPTV is a kind of new service that is combined with the convergence of network, contents, and device. Nevertheless the controversy about the scope and the value of this new convergence service has constantly been raised; for example, what is the difference between IPTV and Internet TV? or what are the benefits that customers can have? This study measured the expectation level and the cognitive level of users before and after using the service and analyzed the gap between the importance and the satisfaction of the service. From this study, we proposed the priority of each function by analysing Importance-Performance Analysis(IPA) method to suggest required functions of IPTV service based on N-Screen technology. This study will identify the gap of awareness level between service providers and end users for the functions of broadcasting and telecommunications convergence service and suggest a solution enhancing user satisfaction.
