Thise study focuses on the direction to the revisions of copyright law in Korea, so that orphan works in libraries can be used more widely on the Internet. In particular, this study analyzes the problems of the provisions 31 and 50 in the copyright law related to the mass digitations of orphan works in libraries. This study also reviews the Directive 2012/28/EU, 3 orphan works bills in USA, and provisions related to the orphan works in The Enterprise and Regulatory Reform(ERR) Act 2013 in UK. Finally this study suggests the 3 directions to support mass digitations of orphan works in libraries. First, digitized orphan works in libraries are to be made a transmission to the public on the Internet; Second, compensation and approval fees are not required or minimized; and third, libraries have to stop the use of the orphan works if copyright owners require. If not, libraries have to negotiate with the copyright owners about the fees necessary.

Most of the convergence studies argue the reform of the current policy regime of broadcasting and telecommunications in Korea from two perspectives: 1) the media governance perspective and 2) the media industry perspective. The former emphasizes the need of integrity, consistency and efficiency of the regime in the convergence environment, while the latter focuses upon the growth and development of the media industry making the best of economic and industrial opportunities that are spawned by digital convergence. Although their arguments are logical and robust, they are lopsided in terms of legalism and myopic economism due to the linear perception of institutionalism, Bureaucratic administrative practices as well as ostentatious IT policies that have chronically plagued the policy regime in Korea cannot be resolved by simply assimilating distinct regulatory bodies and laws. Unless these two issues are properly addressed, the convergence of media policy institutions would end up a half-success or half-failure contrary to the exportations of existing studies.

The interfacial area transport equation dynamically models the changes in interfacial structures along the flow field by mechanistically modeling the creation and destruction of dispersed phase. Hence, when employed in the numerical thermal-hydraulic system analysis codes, it eliminates artificial bifurcations stemming from the use of the static flow regime transition criteria. Accounting for the substantial differences in the transport mechanism for various sizes of bubbles, the transport equation is formulated for two characteristic groups of bubbles. The group 1 equation describes the transport of small-dispersed bubbles, whereas the group 2 equation describes the transport of large cap, slug or chum-turbulent bubbles. To evaluate the feasibility and reliability of interfacial area transport equation available at present, it is benchmarked by an extensive database established in various two-phase flow configurations spanning from bubbly to chum-turbulent flow regimes. The geometrical effect in interfacial area transport is examined by the data acquired in vertical fir-water two-phase flow through round pipes of various sizes and a confined flow duct, and by those acquired In vertical co-current downward air-water two-phase flow through round pipes of two different sizes.

Since 1990s, some events - detection of a dirty bomb in a Russian nation park in 1995, 9/11 terrorist attack to WTC in 2001, discovery of Al-Qaeda's experimentation to build a dirty bomb in 2003 etc - have showed that nuclear or radiological terrorism relating to radioactive materials (hereinafter "radioactive materials" is referred to as "nuclear material, nuclear spent fuel and radioactive source") is not incredible but serious and credible threat. Thus, to respond to the new threat, the international community has not only strengthened security and physical protection of radioactive materials but also established prevention of and response to illicit trafficking of radioactive materials. In this regard, our government has enacted or revised the national regulatory framework with a view to improving security of radioactive materials and joined the international convention or agreement to meet this international trend. For the purpose of prevention of nuclear/radiological terrorism, this paper reviews physical characteristics of nuclear material and existing detection instruments used for prevention of illicit trafficking. Finally, national detection regime against nuclear/radiological terrorism based on paths of the smuggled radioactive materials to terrorist's target building/area, national topography and road networks, and defence-in-depth concept is suggested in this paper. This study should contribute to protect people's health, safety and environment from nuclear/radiological terrorism.

According to the dispostions of 1967 Space Treaty, the contracting states should assume legal obligation to assure an authorization and continuing supervision with regard to the national space activities. Any space activities have to abide by the rules of international law as well as specified obligations set by the Treaty. Among several treaty obligations, International responsibility to be bome by the state, and the liability principles are deemed as major outstanding obligations which the state should takeinto account. While nation's first launch site is to be operational in a few years, korean government should assure that its national space activities, such as launching of space object, operation of satellites, etc. should be under governmental authorization and supervision. A legislative effort would be most desirable undertaking for this regard. Especially a specific legislation needs tobe studied forwith such authorization regime so that international responsibilty and the liability as to thelaunching of space object should be under the regulatory scheme. This study focuses upon the necessity of such legislation and proposes some major items and framework for the legislation

IPTV는 기술적으로 TV에 PC적 기능이 더해지고 인터넷 프로토콜(IP)을 통해 인터넷과 연결되는 서비스로, 국내 초고속인터넷의 속도가 VDSL, 광랜과 같은 서비스의 등장으로 최대 100Mbps에 이르러 동영상 콘텐츠의 실시간 스트리밍 서비스가 가능한 환경이 구현되었다. IPTV 도입을 통해 산사건 방송, VOD 등의 기본적인 서비스뿐만 아니라, 양방향 광고, IPTV 민원발급 및 IPTV 공공서비스 제공 등 다양한 응용서비스의 개발 및 활성화를 기대하였다. 또한 IPTV를 통해 유료방송의 경쟁을 촉진시키고 케이블TV의 디지털 전환을 촉진시킴으로써 시청자들의 복지를 향상시킨다는 취지도 함께 있었다. 정량적으로는 IPTV가입자가 2012년에 이르러 보수적으로 290만가구, 낙관적으로는 450만 가구에 이를 것으로 예상하였으며, 관련 시장규모도 동년도에 약 7,515억원에 이를 것으로 전망하였다. 하지만, 2011년 말이 이미 450만 가입자를 돌파하고 2012년 8월 500만 가입자를 유치하면서 IPTV 서비스는 본격적인 mass market을 형성해 나가고 있다. IPTV 시장이 확대해 나가면서 유료방송 가입가구 수도 증가하였는데, 도입당시인 2008년 말 1,740만 가구가 유료방송에 가입하여 104%의 보급률을 보였으나 2011년 6월말 현재 가구수 대비 유료방송 가입자구수는 127%로 증가하였다. 이렇게 IPTV서비스 시장이 확대되고는 있으나, 정부의 신규 서비스에 대한 과도한 요금규제, IPTV와 경쟁하는 케이블방송사(SO) 계열의 콘텐츠 사업자(CP)들의 방송채널 공급거절 및 지상파 방송사의 과도한 재전송 대가, 전국 권역사업자인 IPTV에 대한 권역별 가입자점유율 규제, IPTV의 차별성으로 내세웠던 T-Commerce 및 양방향 광고에 대한 규제는 앞으로 개선해 내가야할 과제이다. 이에 본고는 IPTV의 시장성과를 조망하고, 시장의 지속성장을 위해 필요한 제도개선 방향을 살펴보았다.

Objectives: In recent years, a number of structurally diverse Histone deacetylase (HDAC) inhibitors have been identified and these HDAC inhibitors induce growth arrest, differentiation and/or apoptosis of cancer cells in vitro and in vivo. This study aimed at investigating the antitumor activity of newly synthesized HDAC inhibitor, 3-(4-dimethylamino phenyl)-N-hydroxy-2-propenamide (IN-2001) using human breast cancer cells. Methods: We have synthesized a new HDAC inhibitor, IN-2001, and cell proliferation inhibition assay with this chemical in estrogen receptor-positive human breast cancer MCF-7 cells. Cell cycle analysis on MCF-7 cells treated with IN-2001 was carried out by flow cytometry and gene expression was measured by RT-PCR. Results: In MCF-7 cells IN-2001 showed remarkable anti-proliferative effects in a dose- and time-dependent manner. In MCF-7 cells, IN-2001 showed a more potent growth inhibitory effect than that of suberoylanilide hydroxamic acid. These growth inhibitory effects were related to the cell cycle arrest and induction of apoptosis. IN-2001 showed accumulation of cells at $G_2$/M phase and of the sub-$G_1$ population in a time-dependent manner, representing apoptotic cells. IN-2001-mediated cell cycle arrest was associated with HDAC inhibitor-mediated induction of CDK inhibitor expression. In MCF-7 cells, IN-2001 significantly increased $p21^{WAF1}$ expression. Conclusions: In summary, cyclin-dependent kinase (CDK) induced growth inhibition, possibly through modulation of cell cycle and apoptosis regulatory proteins, such as CDK inhibitors, and cyclins. Taken together, these results provide an insight into the utility of HDAC inhibitors as a novel chemotherapeutic regime for hormone-sensitive and insensitive breast cancer.

Currently, we are living in the era of the 4th industrial revolution. In the field of shipping industry, the MASS is a revolutionary game changer in the making arising out of such an industrial and technical innovation in the pursuit of radically challenging the pre-existing system of a human-operated vessel. Given this trend, the entire maritime regulatory regime, which has been designed by, and intertwined with, human seaworthiness, abruptly faces the most unprecedented normative confrontations now and increasingly in the coming days. As the constitution of ocean, UNCLOS, provides, every flag state is obliged to effectively exercise its jurisdiction to secure technical and human seaworthiness. Moreover, the coastal state may institute protective proceedings against vessels in respect of any violations of its laws to protect its marine environment in maritime zones of the coastal state. Further, UNCLOS acknowledges that the port state's authority extends to take administrative measures to prevent sub-standard ships from sailing within the ports or offshore-terminals of the state. These three jurisdictional functions will be required to more closely interface with each other than ever over the legal and political implications created by MASS. Although states' jurisdictional nuances are significant in this present world tilting back to protectionism, there are few articles to present jurisdictional issues of states and conceivable normative discourse with regard to MASS. This articles visits potential jurisdictional conflicts underlying MASS and tries to strike balance between contradictory interpretive approaches under UNCLOS while it is undeniable that this doctrinal research tends to strive to find justifications within the current framework of international law.

The power of media has always been problematic in the countries of full press freedom. Originally, the media used to be an effective vehicle for communication within human beings. However, it exerts an overwhelming power toward human society. Through applying the well-known four dog models in terms of media function, this study attempts to examine how the press media in South Korea transformed themselves into another powerful independent organization or institution after regime shift in 1987. The whole editorials of four sampled newspapers were analyzed through frame analysis model. The ChosunIlbo, known as a conservative and pro-government paper, shows to take the role of supporting chaebol policies under Roh TaeWoo Administration. However, it criticizing sharply against the chaebol policies of Roh MooHyun Administration. The JoongangIlbo, known as a pro-chaebol paper, appears anti-government position through the entire four administrations in terms of chaebol policies. Particularly, it reveals hostile editorial coverage during the Roh MooHyun Administration. However, KyunghyangShinmun, currently known as a liberal paper, viewed somewhat complicated positions (see text in more detail) because of its ownership turbulence during the past twenty years. On the other hand, Hangyoreh, regarded as a progressive paper, keeps in supportive attitude consistently against the four sampled administrations as far as regulating each government policies for chaebols.

This paper aims to examine the evolutionary dynamics of the Korea's footwear industry by adopting evolutionary perspectives. To explain the evolutionary dynamics of an industry, evolutionary perspectives have paid a particular attention to exploring a variety of factors for influencing the evolution of the industry, such as the selection and imitation of the firm, the mechanism of firm's entry and exit, technological characteristics and innovation processes. The majority of existing research tend to explain that the decline of the Korea's footwear industry since 1990 was mostly due to the rapid rising of wage and the structural changes in labor-intensive industries. On the contrary, this paper attempts to explain the decline of the Korea's footwear industry, in terms of the path of selection and imitation, the dominant technological paradigm, regulatory frameworks and the meso trajectory of industry evolution. This paper concludes that the decline of the Korea's footwear industry since 1990 was appeared as a result of the evolutionary selection processes of the firms in order to adapt to changes in the environment of competition and the regime of market selection in the global footwear industry.
