  • In this paper, relative service differentiation in JET based optical burst-switched networks with deflection routing is presented. It differs from conventional schemes in that it tries to make the loss rate of high class bursts as low as possible while maintaining the desired proportional ratio between the high class bursts and low class bursts. Strategies applied to it are dynamic wavelength allocation and the preemption which are combined to deflection routing. With dynamic wavelength allocation, the number of wavelengths allocated to high class bursts are dynamically changed. Preemption which gives more preference to high class bursts is also applied to decrease its loss rate. To lower the loss rate, deflection routing is applied for any kind of traffic. With those strategies, the suggested scheme shows desired properties that the loss rate of high class traffic is as lowered as possible. A queueing model for the scheme is developed to approximate loss ratio and the numerical results show that the proposed scheme provisions relative service differentiation.

  • 배우자상속에 있어서 독일 등 다수 선진국들은 배우자 일방의 사망 시 부부재산제에 따른 청산을 통하여 생존배우자를 고정적으로 배우자상속분을 확보해줌과 동시에 철저히 보호를 하고 있는데, 우리나라 가족법에서는 다른 나라들에 비해 생존배우자에게 일정비율의 상속분만을 인정하고 있어 생존배우자의 상속권을 실질적으로 강화될 수 있는 방안이 필요하다고 본다. 특히 2014년 법무부 민법개정위원회의에서 현행법상 배우자 상속제도를 해결하기 위하여 제1008조의4 배우자의 선취분 조항과 제1008조의5 배우자의 선취분 침해에 있어서 회복청구권에 대한 조항신설이 논의 되어 국민들의 높은 호응이 있었음에도 불구하고, 생존배우자 법정상속분을 상향조정을 하게 되면 기업상속 등에 문제가 발생한다는 논리로 개정안은 입법예고도 못하는 상황에 이르게 되었다. 또한 초고령화사회에 살고 있는 생존배우자의 노후생활 보장과 직계비속과 공동으로 상속받는 경우 직계비속의 수에 따라 배우자의 상속분의 유동성 등이 문제점으로 대두되기 때문에 합리적인 생존배우자의 상속분 상향조정되는 입법안이 새롭게 시작되는 21대 국회에서 조속히 마련되기를 기원하는 차원에서 생존배우자의 효율적인 입법방안을 제시하고자 한다.

  • In this paper, service differentiation scheme using optical buffer that is reduced in size with slow-light technology in optical burst switching networks is presented. In suggested scheme, each outport has buffer to store high-class burst only in case that all its wavelengths are occupied. When all wavelengths are being used, a new arriving high-class burst goes into the buffer and waits until a burst is serviced. As soon as a burst is serviced with a wavelength, the high-class burst at buffer is allocated to the free wavelength. In case that low-class burst is arriving under the same situation, it is not stored at the buffer but discarded. An analytical model is derived to analyze the performance of the suggested scheme and compare its performance with the conventional scheme such as preemption and deflection as well as no service differentiations.

  • 최근 몇 년 동안 서울에서는 도시공간에 관한 권리를 둘러싼 격렬한 투쟁이 이어져왔다. 급작스러운 임대료 상승과 그에 뒤따르는 폭력적 전치는 이제 도시생활의 일상적 의례의 하나로 자리잡은 듯하다. 흔히 '젠트리피케이션'으로 명명되는 도시공간의 자본화는 한편으로 도시 내 계급지배가 관철되는 대표적 양상이지만, 다른 한편으로는 다양한 형태의 도시운동이 발생하는 조건과 배경으로도 작용한다. 이 논문에서는 최근 서울의 도시공간에서 발견되는 도시운동의 새로운 형태들을 2010년 이후 등장한 세 개의 도시 운동 집단, '맘편히장사하고픈상인모임(맘상모),' 리슨투더시티, 비빌기지에 초점을 맞춰 검토한다. 구체적으로 이 글에서는 도시공간에 대한 이들의 대안적 상상과 실천의 형성 과정을 서울의 젠트리피케이션이라는 맥락에서 살펴보고, 이들이 제시하는 도시운동의 '새로움'을 과거의 도시운동과 비교 분석하며, 도시운동으로서 이들의 실천이 지닌 함의를 도시권의 관점에서 고찰한다. 내용과 형식의 다양성에도 불구하고 이들 집단의 행동은 몇몇 핵심적 특성을 공유한다. 첫째, 이들은 공동재(commons)로서의 도시공간을 추구한다. 둘째, 이들은 느슨하고 유연하며 소규모의 조직을 지향한다. 셋째, 이들은 예술과 문화를 주체형성에 적극적으로 동원한다. 이러한 특성들은 철거민운동으로 대표되는 전통적 계급 기반 도시운동과 뚜렷한 차이를 나타내며, 계급 이후(post-class) 도시권의 전망을 선취한다.

  • 본 논문에서 필자는 수학에 대한 구조주의적 해석들은 수학의 객관성을 설명하는 문제인 비공허성의 문제를 해결하지 못하고 있음을 보이고자 한다. 제거적 구조주의가 비공허성의 문제를 해결하지 못한다는 것은 대부분의 수학철학자들 사이에서 공유되는 견해이며, ante rem 구조주의는, 케래넨의 논증을 수정한 필자의 강한 논증에 의하면, 수학적 대상들에 대한 적절한 동일성 설명을 결코 제공할 수 없기 때문에, 결국 비공허성의 문제를 해결하지 못한다. 또한, 양상 구조주의자인 헬만의 경우에는, 비공허성의 문제에 대한 양상 구조주의적 해결을 가능케 해주는 주장(산수와 관련하는 경우, "${\omega}$-순서열 체계가 논리적으로 가능하다")에 이르는 그의 증명이, 필자의 판단에 따르면, 논점 선취의 오류를 저지르고 있다.

  • Go bears significant meanings in terms of cultural and entertaining functions in Asia Eastern such as China and Japan. Beyond the mere entertaining level, it produces philosophical and mythic discourse as well. As a part of effort to seek an identity of Korean traditional garden culture, this study traced back to find meanings of rock-go-board and taste for the arts which ancestors pursued in playing Go game, through analysis and interpretation of correlation among origin of place name, nearby scenery, carved letters and vicinal handed-down place name. At the same time, their position, shape and location types were interpreted through comprehensive research and analysis of stone-go-boards including rock-go-board. Particularly, it focused on the rock names related to Sundoism(仙道) Ideal world, fixed due to a connection between traces of Sundoism and places in a folk etymology. Series of this work is to highlight features of the immortal sceneries, one of traditional landscaping ideals, by understanding place identity and scenic features of where the rock-go-boards are carved. These works are expected to become foundation for promotion and preservation of the traditional landscaping remains. The contents of this study could be summarized as follows; First, round stone and square board for round sky and angled land, black and white color for harmony of yin and yang and 361paths for rotating sky are symbols projecting order of universe. Sayings of Gyuljungjirak(橘中之樂), Sangsansaho(商山四皓), Nangagosa(爛柯故事) formed based on the idea of eternity stand for union of sky and sun. It indicates Go game which matches life and nature spatiotemporally and elegant taste for arts pursuing beauty and leisure. Second, the stone-go-boards found through this research, are 18 in total. 3 of those(16.1%), Gangjin Weolnamsaji, Yangsan Sohanjeong and Banryongdae ones were classified into movable Seokguk and 15(83.9%) including Banghakdong were turned out to be non-movable rock-go-boards carved on natural rocks. Third, upon the result of materializing location types of rock-go-boards, 15 are mountain stream type(83.9%) and 3 are rock peak type(16.1%). Among those, the one at Sobaeksam Sinseonbong is located at the highest place(1,389m). Considering the fact that all of 15 rock-go-boards were found at mountainous areas lower than 500m, it is recognizable that where the Go-boards are the parts of the living space, not far from secular world. Fourth, there are 7 Sunjang(巡將) Go with 17 Hwajeoms(花點), which is a traditional Go board type, but their existences, numbers and shapes of Hwajeom appear variously. Based on the fact, it is recognizable that culture of making go-board had been handed down for an extended period of time. Among the studied rock-goboards, the biggest one was Muju Sasunam[$80(82)cm{\times}80(82)cm$] while the smallest one was Yangsan Sohandjeong Seokguk ($40cm{\times}40cm$). The dimension of length and breadth are both $49cm{\times}48cm$ on average, which is realistic size for actual Go play. Fifth, the biggest bed rock, an under-masonry with carved Go-board on it, was one in Muju Sasunam[$8.7m{\times}7.5m(65.25m^2)$], followed by ones in Hoengseong Chuiseok[$7.8m{\times}6.3m(49.14m^2$] and Goisan Sungukam[$6.7m{\times}5.7m(37.14m^2)$]. Meanwhile, the smallest rock-go-board was turned out to be one in Seoul Banghak-dong. There was no consistency in directions of the Go-boards, which gives a hint that geographical features and sceneries of locations were considered first and then these were carved toward an optimal direction corresponding to the conditions. Sixth, rock-go-boards were all located in valleys and peaks of mountains with breathtaking scenery. It seems closely related to ancestors' taste for arts. Particularly, rock-go-boards are apprehended as facilities related to taste for arts for having leisure in many mountains and big streams under the idea of union of sky and human as a primitive communal line. Go became a medium of hermits, which is a traditional image of Go-game, and symbol of amusement and entertainment with the idea that Go is an essence of scholar culture enabling to reach the Tao of turning back to nature. Seventh, the further ancient time going back to, the more dreamlike the Go-boards are. It is an evident for that Sundoism, which used to be unacceptable once, became more visible and realistic. Considering the high relation between rock-go-boards and Sundoism relevant names such as Sundoism peak in Danyang Sobaeksan, 4 hermits rock in Muju and Sundoism hermit rock in Jangsu, Sundoism hermit rocks and rock-go-boards are sceneries and observation spots to express a communication of worship and longing for Sundoism. Eighth, 3 elements-physical environment such as location type of the rock-go-boards, human activities concentrated on 8 sceneries and Dongcheongugok(洞天九曲) setup and relevancy to Confucian scholars, as well as 'Sangsansaho' motif and 'Nangagosa' symbolic meaning were used as interpretation tools in order to judge the place identity. Upon the result, spatial investigation is required with respect to Sunyoodongcheon(仙遊洞天) concept based on enjoyment to unify with the nature rather than Dongcheongugok concept of neo-Confucian, for Dongcheon and Dongmoon(洞門) motives carved around the rock-go-boards. Generally, places where mountain stream type rock-go-boards were formed were hermit spaces of Confucianism or Sundoism. They are considered to have compromised one other with the change of times. Particularly, in the rock-go-board at the mountain peak, sublimity-oriented advent of Sundoism is considered as a significant factor to control place identity. Ninth, including where the rock-go-boards were established, the vicinal areas are well-known as parts of Dongcheongugok and Palkyung(八景) mostly. In addition, many of Sundoism relevant expressions were discovered even in the neighboring carvings written by scholars and nobility, which means sophisticated taste based on longing for Sundoism world played a significant role in making go-board. The rock-go-board is an integration of cultural phenomena naturally managed by seclusion of scholars in the Joseon Dynasty as well as remains and essence of Korean traditional landscaping. Some rock-go-boards out of 17 discovered in South Korea, including ones in Sobaeksan Sinsunbong, Banghak-dong, Chungju Gongili, Muju Sasunam, Yangsan Eogokdong Banryongdae Seokguk, are damaged such as cracks in rocks or fainted lines by hardships of time and hand stains. Worse yet, in case of Eunyang Bangudae Jipcheongjeong board, it is very difficult to identify the shape due to being buried. Rock-go-boards are valuable sculptures in terms of cultural asset and artwork since they reflect ancestors' love for nature and longing for Sundoism world. Therefore, they should be maintained properly with right preservation method. Not only rock-boards itself but also peripheral places are excellent cultural heritages and crucial cultural assets. In addition, vicinal sceneries of where rock-goboards and pavilion spots are the representative remains of embracing prototype of Korean traditional landscaping and major parts of cultural properties.
