Tight Upper Bound for Stability of TCP/RED Systems in AQM Routers

Seok Woo,Kiseon Kim IEEE 2010 IEEE communications letters Vol.14 No.7

<P>Stability of TCP/RED systems can be achieved by tuning random early detection (RED) parameters. The authors present a tight upper bound of the maximum packet drop probability in the RED to obtain a stable queue performance in TCP/RED systems. Simulation results show that the derived stability condition is exact and match up well to our analysis.</P>

Dual voice and submerged authorial intention in Virginia Woolf 's A Room of One's Own

Seokwoo Kwon 국제언어인문학회 2021 인문언어 Vol.23 No.1

There has been still a controversy about the conflicts between radical feminism and feminism of androgyny, so called the duel between stage two and stage three feminism if we use Julia Kristeva (209), although this kind of dichotomy is almost losing its ground when she says the latter one does not necessarily negate the former because all three feminisms are required and needed for the liberation of women. But the issue here lies at the fact that the harmonious androgyny is still precociously utopian even today when practical feminist issues including abortion and genital mutilation have not been yet remarkably resolved so far. Theories of radical feminism and the debate between stage two and three are still paradoxically needed to lay a foundation on to solve those practical problems of the society. Virginia Woolf’s famous feminist manifesto, A Room of One's Own (1929) is, therefore, still a good literary work to deal with this issue of which is a good or “the” best feminist position. Woolf could formulate and contain her idea of radical feminism in the age of Victorian-Edwardian England in which potently surveillant patriarchy prevailed, while hiding and camouflaging her feminist anger enveloped within the surface of androgyny. Again, however, despite risking the fallacy of authorial intention, which one is Woolf's real voice out of these two? Femininity or Androgyny? The expressed one or the suppressed one behind this narrative? Both or neither? My argument is that Woolf could reveal her anger and rage while pretending to conceal her radical notion of femininity under utopian androgyny. In spite of her fear of being called a radical or sometimes a sappy feminist, she could praise femininity by using multiple personae and evasive narrative technique.

The Case concerning Whaling in the Antarctic (Australia v. Japan; New Zealand intervening)

Seokwoo Lee(이석우) 인하대학교 법학연구소 2013 法學硏究 Vol.16 No.3

1946년 12월 포경의 남용으로부터 고래를 보호하기 위해 포경규제에 관한 국제협약(International Convention for the Regulation of Whaling: ICRW)이 체결되었다. 이 협약 제8조는 당사국이 일정한 조건에 따라 과학적 연구를 목적으로 하는 자국민의 포경을 특별허가 할 수 있도록 규정하고 있다. 그런데 ICRW 제3조를 근거로 설립된 국제포경위원회(International Whaling Commission, IWC)는 1980년대 이후 무분별한 포경으로부터 고래를 보호하기 위해 포경에 대한 규제를 강화하기 시작했다. 즉, IWC는 1982년 ICRW의 중요한 부속문서인 명세서(Schedule) 제10항에 (e)를 추가해서 1985/86년 이후 모든 종류의 고래에 대한 상업적 목적의 포경을 금지하였다. 그리고 IWC는 1994년 명세서 제7항에 (b)를 추가하여 남대양 서식지(Southern Ocean Sanctuary)에서의 상업적 포경을 금지하였다. 그 동안 여러 국제기구 회의와 외교적 경로를 통해 일본의 포경행위를 지속적으로 비난하며 중단을 요구해 온 호주는 2010년 5월 31일 포경에 관한 국제적 의무를 위반했다며 일본을 국제사법재판소(ICJ)에 제소하였다. 일본정부는 IWC의 포경 규제강화 이후에도 계속해서 연구목적이라는 구실 하에 민간 어선이 일본 정부의 특별허가를 받아 포경을 할 수 있도록 하는 고래연구프로그램(JARPA II)을 실시해 왔다. 호주는 JARPA II에 따라 일본 어선이 대량의 포경을 하도록 하는 것은 곧 일본이 ICRW상 당사국의 의무를 위반한 것이라고 주장하였다. 본 논문은 협약 제8조를 둘러싼 호주와 일본간의 법리 공방을 중심으로, ICJ에서의 재판결과에 상관없이 향후 IWC 체제의 유지 차제가 부정적이라는 함의를 도출하고 있다. The Case Concerning Whaling in the Antarctic is primarily based on a dispute over the interpretation of the International Convention for the Regulation of Whaling (ICRW). Article VIII provides that “any Contracting Government may grant to any of its nationals a special permit authorizing that national to kill, take and treat whales for purposes of scientific research . . . .” (emphasis added). Utilizing this exception, Japan announced the Japanese Whale Research Program under Special Permit in the Antarctic (JARPA) in the 1987/88 season. Japan commenced the Second Phase of the Japanese Whale Research Program under Special Permit in the Antarctic (JARPA II) during the 2005/6 season. The stated objectives of JARPA II include monitoring the Antarctic ecosystem, modeling competition among whale species, clarifying changes in stock structure, and improving the management of minke whale stocks. After research is conducted, meat from harvested whales is sold for consumption and profits are used to support the Institute for Cetacean Research. On 31 May 2010, Australia instituted proceedings against Japan in the ICJ. Australia filed its memorial on May 9, 2011, and Japan filed a counter-memorial on March 9, 2012. On 20 November 2012, New Zealand filed a Declaration of Intervention in the Registry, and the Court granted permission to intervene on 6 February 2013. Australia claims that Japan’s large scale whaling under JARPA II violates its obligations under the ICRW, as well as its other international obligations for the preservation of marine mammals and marine environment under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the Convention on Biological Diversity (CBD). Japan however argues that the Court lacks jurisdiction over Australia’s claims, and that, as a result, New Zealand’s application to intervene lapses. In the alternative, Japan argues that Australia’s claims should be rejected because the whaling activities are conducted for the purposes of scientific research, which is permitted under the ICRW. Australia counters that Japan is engaging in commercial whaling under the guise of “research.” A public hearing was held from on 26 June to 16 July 2013. The Court’s judgment will be rendered at a public sitting but is not expected for several months. This is the first time for Japan to appear as a party to a dispute at the ICJ. For Australia, it is the first time since the 1973 Nuclear Test case for the country to institute proceedings; it last appeared in the ICJ as the Respondent in the East Timor case which began in 1991. If the judgment is unfavorable to Japan, the country might withdraw from the IWC. In the past, Japan has threatened to do so and form an alternative ? and presumably more whaling-friendly ? organization. Such actions will probably initiate a domino effect among other pro-whaling countries. Alternatively, if the judgment favors Japan, the IWC may regain credibility among pro-whaling countries that feel isolated due to the organization’s increasingly conservationist stance. In addition, such a decision may encourage anti-whaling countries to be more flexible in their stance against whaling.

A Methodology for Deriving Safety Boundaries of Nuclear Power Plants Against Unmanned Aerial Vehicle Attacks

Seokwoo Sohn,Hyeseung Kim,Sundo Choi 한국방사성폐기물학회 2022 한국방사성폐기물학회 학술논문요약집 Vol.20 No.2

UAVs (Unmanned Aerial Vehicle) are a rising threat to national facilities due to their cheap price and accessibility. Incidents such as the terrorism attack in Saudi Arabia’s oil facilities and the paralysis of the airport system in England’s Gatwick airport shows the need for integrating CUAS (Counter- Unmanned Aerial Systems) in important national facilities. Recently efforts have been made to evaluate the technical performance of the CUAS. Especially SNL (Sandia National Laboratory) modified the methodology used for PPS (Physical Protection Systems) to develop a performance metrics for CUAS. The performance metrics can be used to effectively analyze the facilities capability of countering drone attacks in a probabilistic way. In this study, we managed to derive the safety boundary of a reference nuclear power plant model based on its current CUAS and protection capabilities with a simplified methodology. Based on the outermost boundary of the model, the time table of the UAS consist of 4 variables which are the assessment time, transmission time, neutralization time and the maximum vehicle velocity. Dividing the maximum velocity to the net time derived, we estimated the minimum sensing point of the CUAS which is the minimum safety boundary of the facility to safely manage the UAV attack. Two practice cases were evaluated with the methodology which is based on the UAV groups classified by the United States DOD (Department Of Defense) that matches the classification of the UAV in Korea. Each variable was assumed to fit the process of a realistic nuclear power plant. Using the variables, we calculated the minimum safety boundary of the facility. With the methodology introduced in this study, regulators and stakeholders can easily evaluate the capability of the facilities CUAS for a design basis UAV attack. Also it can be used as a simple tool to analyze the facilities vulnerability for specific UAV specifications and a guideline to check the protective procedures of the facility.
