본 논문에서는 잊혀질 권리에 대한 법정책적 검토를 논하고자 한다. 잊혀질 권리는 다른 기본권과 충돌할 수밖에 없기 때문에 이 권리를 법률로 구체화하는데 다각적인 학제 간 연구가 선결문제로써 검토되어야 한다. 정보 주체에게 잊혀질 권리를 법제화하는 것은 그 정보를 사용하려는 사람의 표현의 자유 및 국민의 알권리를 제한하는 결과를 초래하기 때문에 일정한 한계를 노출할 수밖에 없다. 비록 현행 개인정보보호법 및 정보통신망 이용촉진 및 정보보호 등에 관한 법률 제44조의 2는 개인정보의 파기제도를 신설하여 부분적으로 잊혀질 권리를 반영하고 있지만 헌법상 중요한 가치인 프라이버시권과 표현의 자유 및 알권리의 조화롭게 균형을 찾는 것이 선행과제인 것이다.

This paper try to explain the phenomenon on convergence of broadcasting and telecommunication by the law of the tendential fall in the rate of profit. With the progressive decline in the variable capital in relation to the constant capital in the sphere of the telecommunication, this tendency leads to a rising organic composition of the total capital, and the direct result of this is that the rate of surplus-value, with the level of exploitation of labour remaining the same or even rising, is expressed in a steadily falling general rate of profit. The reason to apply this law is to inquire into the true state of the phenomenon on convergence of broadcasting and telecommunication showed like the disorderly development.

In this paper, we analyze the paradigm shift of radio policy with the development of radio technology. In particular, we propose the definition of spectrum sharing, which is now omitted in the Korean radio law, and analyze the category of spectrum sharing depending on the licensing regime. Also we propose to extend the spectrum usage right, which defines only exclusive usage rights by spectrum auction in the Korean radio law, to all the stations which use radio spectrum and to restructure the Korean radio law.

The properties of a scale-free network are little known; its node degree following a power-law distribution is among its few known properties. By selecting real-field scale-free networks from a network dataset and comparing them to other networks, such as random and non-scale-free networks, the topology characteristics of scale-free networks are identified. The assortative coefficient is identified as a key metric of a scale-free network. It is also identified that most scale-free networks have negative assortative coefficients. Traditional generation models of scale-free networks are evaluated based on the identified topology characteristics. Most representative models, such as BA and Holme&Kim, are not effective in generating real-field scale-free networks. A link-rewiring method is suggested that can control the assortative coefficient while preserving the node degree sequence. Our analysis reveals that it is possible to effectively reproduce the assortative coefficients of real-field scale-free networks through link-rewiring.

In this paper, we propose a novel differential equation method for designing a total internal reflection (TIR) LED lens with double freeform surfaces. A complete set of simultaneous differential equations for the method is derived from the condition for minimizing the Fresnel loss, illumination models, Snell’s Law of ray propagation, and a new constraint on the incident angle of a ray on the light-exiting surface of the lens. The last constraint is essential to complete the set of simultaneous differential equations. By adopting the TIR structure and applying the condition for minimizing the Fresnel loss, it is expected that the proposed TIR LED lens can have a high luminous flux efficiency, even though its beam-spread angle is narrow. To validate the proposed method, three TIR LED lenses with beam-spread angles of less than 22.6° have been designed, and their performances evaluated by ray tracing. Their luminous flux efficiencies could be obviously increased by at least 35% and 5%, compared to conventional LED lenses with a single freeform surface and with double freeform surfaces, respectively.

Data mining has broad applications that reach beyond scholarly and scientific research and provide internet search engine services that are commonly used forms of Text and Data Mining('TDM') of websites. The exceptions and limitations for data mining provide a competitive advantage in the global race for policy innovation because it permits researchers to conduct computational analysis - TDM on any materials to which they have access. For this purpose, Japan and the EU added limitations on copyright to legalize some TDM research through amendments to copyright law, and the U.S. copyright law has allowed data mining by the fair use provision. On the other hand, there are no explicit exceptions and limitations for data mining under the Korean Copyright Act, and there are no cases considering data mining fair use. We review comparatively exceptions and limitations on copyright which will help to encourage AI-related business by using more data smoothly through the mining process and extracting more valuable information.

The benefits of infrastructure support are shown by analyzing a throughput scaling law of an erasure network in which multiple relay stations (RSs) are regularly placed. Based on suitably modeling erasure probabilities under the assumed network, we show our achievable network throughput in the hybrid erasure network. More specifically, we use two types of physical models, a exponential decay model and a polynomial decay model. Then, we analyze our achievable throughput using two existing schemes including multi-hop transmissions with and without help of RSs. Our result indicates that for both physical models, the derived throughput scaling law depends on the number of nodes and the number of RSs.

The relation of multicast transmission and directional antennas is an open problem that has been debated for a long period of time. In this paper, we propose a group-aware multicast scheme of efficient multicast communication using the directional antennas for 60GHz millimeter wave wireless networks. For this purpose, we first derive the relation among beamwidth, distance between devices and most suitable data rate in the 60GHz frequency-based wireless network. In addition, for the dynamic beamforming of multicast communication, the x and y coordinates of any point with sender device at the center is generated, and a best-chosen group is deduced based on the Euclidean distance. Then the most suitable data rate for the group is obtained using the law of cosine. Using the Standard IEEE 802.11ad MAC protocol as an example, extensive simulation results demonstrate that the proposed scheme outperforms the existing multicast communication schemes with directional antennas under different situations.

The article is devoted to the problems and prospects of integration of informational technologies in the administration of justice as a necessary component of the development of the informational society in Ukraine. In general, informational technologies make it possible to create new forms of organization and interaction of bodies of public authorities with society, to introduce innovative solutions for legal regulation and organization of public relations. More and more services for citizens are moving to electronic format. Judicial reform is aimed at ensuring more comfortable and convenient interaction with the courts. The need for the usage of informational technology in the proceedings is preconditioned by the global informatization of modern society, the development of new forms of interaction in the civil sphere with the usage of electronic means of communication: the global Internet, mobile, and satellite communication systems and more. "Electronic justice" involves the use of information and communication technologies in the implementation of procedural law.
