  • 본 연구에서는 동적 점탄-점소성 구성식에 기초한 다층지반의 1차원 액상화 해석을 수행하였다. 일본 고베 포트아일랜드에서 발생한 1995 Hyogoken Nanbu 지진에 대하여 지반 모델링을 하였으며, 사질토 지반에는 탄소성 모델을, 점성토 지반에는 점탄-점소성 모델 및 탄-점소성 모델을 각각 적용하였다. 본 연구 결과, 모델 지반의 경우 지표 10 m 아래를 전후하여 액상화가 발생하였으며 액상화가 발생한 지반을 통과하는 지진파는 감쇠특성을 나타내고 이 때 전단변형률을 크게 증가시켰다. 또한, 대변형률 영역에서의 점성토의 동적거동 해석에서는 점소성 거동특성이 지배적이므로 점소성 모델의 적용이 중요함을 알 수 있었다. 한편 동적 점탄-점소성 구성모델은 대변형률 영역에서 점성토의 소성변형을 유발하는 대형 지진 발생시 점성토의 증폭 및 감쇠특성 분석에 적용 가능한 모델임을 확인하였다.

  • 융합환경 하에서 새로운 기술과 서비스의 제공이 가능해지고 차세대 네트워크의 투자가 확대되면서 미래 통신시장에서 유선부문 지배적 사업자의 시장지배력이 전이될 가능성이 높아지고 있다. 이러한 통신시장의 환경변화에 대응하여 영국, 이탈리아, 스웨덴, 아일랜드 등 유럽의 많은 국가가 구조분리를 추진하였거나 진행중에 있다. 또한 EU는 2007년 11월 통신법 개정안을 통해 EU 27개 회원국 규제기관에 영국식 기능분리 권고안을 제안하였고, 개별 회원국의 찬성을 전제로 2009년 구조분리가 현실화 될 예정이다. 특히 EU의 통신법 개정안은 기존 병목설비에 적용되던 필수성과 독점성의 원칙을 상당히 탄력적이고 포괄적으로 해석하고 있다. 또한 유선시장의 경쟁 상황이 점차 개선되고 있음에도 구조분리를 강력하게 추진하고 있다. 이처럼 컨버전스 환경에 대비한 EU 및 유럽 각국의 강력한 구조분리 추진현황은 유선시장의 경쟁이 활발하지 않고, 구조분리 논의가 필수설비의 필수성과 독점성의 원칙에서 진전되지 못하고 있는 우리나라의 유선시장에 많은 시사점을 제시하고 있다.

  • 전기, 전자, 우주, 자동차, 무기 등의 여러 분야에서 응용되고 있는 고정밀, 고저항체 박막인 TaNx 다층박막을 반응성 마그네트론 스퍼터링법으로 제조하여 질소분압에 따른 TCR 특성 변화를 조사하고, XRD와 SEM 관찰을 통하여 미세조직이 전기적 성질에 미치는 영향을 알아보았다. 제조된 TaNx 박막의 전기저항은 질소분율이 증가함에 따라 저온보다 고온에서 전기저항이 감소함을 보여 뚜렷한 (-)TCR 특성을 나타내었다. XRD 분석 결과, $Ar/N_2$ 비가 0.05에서 TaN 상이 형성되고 0.1에서 우수한 결정성을 나타내었으며, $N_2$의 양이 증가할수록 비정질이 형성되었다. 박막의 표면 형상은 미세하고 불연속 아일랜드 형태로 변화하였다.

  • To ensure the mobility of the UE(User Equipment), the handover phenomenon occurs depending on the level and quality of the radio signal. According to the set of handover event, the threshold of handover is changed. In this paper, we analyze the handover performance using LTE KPI(Key Performance Indicator) of measurement mobile traffic data in Ireland.

  • This paper, we propose a multi-population differential evolutionary algorithm using MUDE (Uniform Local Search) to recognize various mutation strategies. In MUDE, a population is divided into several subpopulations with different population sizes that perform different mutation strategies according to evolutionary ratios (DE/rand/1 and DE/current-to-rand/1). To improve population diversity, information is migrated between subpopulations by a soft island model.

  • The purpose of this study was to assess the genetic variation and establish the relationship amongst breeds and strains using 7 chicken specific microsatellite markers. A total of 317 DNA samples from four Korean native chicken (KNC) strains (KR: Korean Native Red chicken strain, KY: Korean Native Yellow chicken strain, KL: Korean Native Black chicken strain, KO: Ogol chicken strain) and three introduced endemic chicken breeds (LE: Leghorn chicken breed, RI: Rhode Island Red chicken breed, CO: Cornish chicken breed). The size of microsatellite markers was decided using GeneMapper Software (v.4.0) after being analyzed using an ABI 3130 Genetic Analyzer. Frequencies of microsatellites markers were used to estimate heterozygosities and genetic distances. The lowest distance (0.074) was observed between the KY and KL breeds and the highest distance (0.779) between the KL and LE breeds. The KNC strains (KR, KY, KL) have comparatively near genetic distance each other. On the other side, each individual was not ramified to different groups and were spread evenly in phylogenetic dendrogram about all the KNC of each strain populations. But the endemic breed populations (LE, RI, CO) were ramified to different groups. The microsatellite polymorphism data were shown to be useful for assessing the genetic relationship between Korean native strains and other foreign breeds.

  • This study was carried out to suggest the basic data of planting method for construction of buffer green space based on the land use in case of reclaimed land by analyzing land structure, planting concept, and planting structure in buffer green space, Rokko Island, Kobe, Japan. Rokko Island(total area: 580ha) is divided into port and logistics industry area and urban area by constructing the box type large-scale buffer green space. The land structure of buffer green space were biased mounding type, parallel mounding type, and complex mounding type. The width of buffer green space was 50meters in case of northern area, from 28 to 32meters in case of eastern area, and 37.5meters in case of western area, and the slope of that was from 18 to 25 degrees and the height of that was from 2 to 15meters. There were applied landscape and buffer planting concept on the sea side area of northern buffer green space, on the other hand landscape and shade planting concept on the Inner city side area of that. According to the result of planting structure analysis of northern buffer green space, the main woody species were those of deciduous-evergreen species grow in warm-temperate forest zone such as Quercus glauca, Cinnamomum camphora, Machilus thunbergii, Elaeagnus maritima. The results of maximum number of species and planting density by $100mm^2$ was that 9 species 22 individuals in canopy layer, 9 species 15 individuals in understory layer, 3 species 67 individuals in shrub layer, and 14 species 104 individuals in total. The plant coverage of northern buffer green space based on the ecological planting method was from 69 to 139% in case of canopy layer, from 26 to 38% in case of understory layer, from 6 to 7% in case of shrub layer, and from 101 to 184% in total. Index of plant crown volume of northern buffer green space based on the ecological planting method was from 1.40 to $3.12m^3/m^2$ in case of canopy layer, from 0.43 to $0.55m^3/m^2$ in case of understory layer, $0.06m^3/m^2$ in case of shrub layer, and from 1.89 to $3.73m^3/m^2$ in total.

  • Aristotle's Poetics is the earliest work of dramaturgy. It explains some of the most important narrative notions, for example, Mimesis, Katharsis, Mythos(Plot), Ethos(Character), Anagnorisis and Peripeteia. etc. Aristotle considered the plot which is the arrangement of events, as the most important element of drama. This paper presents an example of a plot configuration as an alternative to the traditional narration used since Aristotle. Dead Island, developed by Techland and published by Deep Silver, is one of the most successful action role-playing survival zombie video games. Its trailer, the Winner of Gold Prize for Internet Film at Cannes Lions International Festival of Creativity in 2011. Since the purpose of the trailer is to attract the audiences/gamers to the film/game, it has generally a similer narrative method from its own works. But Dead Island trailer is different. We treat this trailer as an short animation. It could be a new example of the non-linear narrative by the control of the time for example, temporal arrangement, direction and speed. We analyse all shots of Dead Island's trailer with Poetics' rules and with $G{\acute{e}}rard$ Genette's some narrative notions for example temporal order and duration. Furthermore we look for how to maximize the audiences' curiosity by the adjustment of the time, combined with its shocking images.

  • Public awareness campaign is the core factor of the national suicide prevention strategies. Korea's current campaign needs to be more systematically developed. This study analyzed the national-level campaigns for suicide prevention of New Zealand, USA, Ireland, Scotland, and Australia whose campaigns were known to be successful, and compared them with those of Korea. With the analysis framework based on the 'Guideline for Effective Health Communication Campaigns' by the U.S. Department of Health and Human Services, we examined the campaigns from the dimensions of (1) clarity of goals, (2) appropriacy of targeting strategies, (3) suitability of messaging strategies, and (4) efficiency of performance. The results show that effective campaigns for suicide prevention have the following common factors: (1) campaign appellations which include clear goals, (2) targeting at risk groups considering social contexts, (3) slogans which contains specific action guidelines, and (4) close relationships between public and private sectors. On this basis, future directions for more effective suicide prevention media campaigns in Korea are discussed.
