애니메이션 작품에서는, 캐릭터의 내적갈등을 효과적으로 전개하고 주제를 강화하기 위한 주요한 전략의 하나로서 공간을 성격화한다. 내적갈등의 과정은, 캐릭터가 결핍에 의해 형성된 두려움으로부터 자아를 보호하기 위하여 무의식적 차원에서 방어기제를 사용하며, 그 자기기만적 속성 때문에 현실이 왜곡되며 갈등이 강화되는 것으로 구체화된다. 본 논문은 애니메이션에 나타나는 공간의 구분에 있어서 갈등이 심화되는 공간인 '안티돔'의 개념에 주목하고, 작품 분석을 통해 내적갈등의 양상과 공간의 특성을 '은유 구조의 틀'로 해석하여, 캐릭터의 내적갈등을 증폭시키는 방어기제의 작용이 '안티돔'으로 성격화되는 그 근원적 관계성을 밝히고자 했다. 분석은 <신세기 에반게리온>의 TV 시리즈와 극장판 를 중심으로 이루어졌다. 이는 극중의 캐릭터들이 모두 심각한 가정사적 결핍과 A.T.필드로 상징되는 배타적 경계의 심리적 속성을 공유하고 있다는 점과, 무엇보다도 핵심 캐릭터인 '이카리 신지'를 통해 내적갈등에 대한 강박적 방어기제의 사용, 그 결과로 나타난 자아의 붕괴와 성찰의 과정을 전체 플롯의 핵심 맥락으로 묘사하고 있기 때문이다. 분석을 통해서, 캐릭터의 방어기제와 '안티돔(안티고로드로 확장된)' 공간과의 유사적 관계를 추론하였으며, (1) X축의 '수평공간'과 (2) Y축의 '수직공간', (3) 모든 공간이 '탈출구가 존재하지 않는' 구조로 이루어졌다는 의미에서 Z축의 '모순의 심도 공간'으로 구축되어 있다는 결론을 도출할 수 있었다. 본 논문은, 방어기제와 안티돔의 은유 관계 분석에 있어서 첫 출발의 의미로, <에반게리온>이 가장 적합한 분석 작품이라는 판단에 의해 시작되었다. 그러나 일본 애니메이션 특유의 현학적 구성과 확장적 해석의 가능성 때문에 오히려 명료한 검증이 어려웠다는 점이 연구의 한계로 작용했다. 후속 연구를 통해 보완되기를 바라며, 본 논문이 애니메이션 텍스트의 해석에 있어서 공간의 중요성을 제고하고, 창작을 위한 데이터베이스로 기능할 수 있기를 기대한다.

Denial of Service (DoS) attack is to interfere the normal user from using the information technology services. With a rapid technology improvements in computer and internet environment, small sized DoS attacks targeted to server or network infrastructure have been disabled. Thus, Distributed Denial of Service (DDoS) attacks that utilizes from tens to several thousands of distributed computers as zombie PC appear to have as one of the most challenging threat. In this paper, we categorize the DDoS attacks and classify existing countermeasures based on where and when they prevent, detect, and respond to the DDoS attacks. Then we propose a comprehensive defense mechanism against DDoS attacks in Control System to detect attacks efficiently.

Catalytic iminohydroacylation has been achieved by the reaction of aldimine 1 and 1,5-hexadiene (2a) with Wilkinson's complex as catalyst. Compounds 7a, 8a and 9a were obtained as final product after hydrolysis of the resulting iminohydroacylation products 4a, 5a and 6a. Depending on the reactant ratio (2/1), the ratio of products were changed dramatically : As the 2/1 ratio was increased, 7a is the major product after hydrolysis while 8a is the major with an 1/1 ratio of 2/1. The mechanism of the formation of 5a is determined by the reaction of 1 and 2b under the identical reaction conditions. Considering that 5a may not be formed from the hydroiminoacylation of 14a since 5b cannot be formed from that of conjugate diene 14b generated from isomerization of 2b, 5a must be formed from the reaction of 4a and 10 by addition-elimination mechanism.

The objective of this study is to reveal the sintering mechanism of mixed Ti-6Al-4V powders considering the densification and the homogenization between Ti and Al/V particles. It is found that the addition of master alloy particles into Ti enhances densification by the migration of Al into the Ti matrix prior to the self-diffusion of Ti. However, as Ti particles become coarser, sintering of the powders appears to be retarded due to slower inter-diffusion of the particles due to the reduced surface energies of Ti. Such phenomena are confirmed by a series of dilatometry tests and microstructural analyses in respect to the sintering temperature. Furthermore, the results are also consistent with the predicted activation energies for sintering. The energies are found to have decreased from 299.35 to $135.48kJ{\cdot}mol^{-1}$ by adding the Al/V particles because the activation energy for the diffusion of Al in ${\alpha}-Ti$ ($77kJ{\cdot}mol^{-1}$) is much lower than that of the self-diffusion of ${\alpha}-Ti$. The coarser Ti powders increase the energies from 135.48 to $181.16kJ{\cdot}mol^{-1}$ because the specific surface areas of Ti decrease.

In the case study of this paper, sensitivity experiments are carried out using the mesoscale non-hydrostatic Weather Research and Forecasting (WRF) model to investigate the impact of tropical cyclone (TC) Soudelor (2003) on the East Asian subtropical upper-level jet (EASJ) before TC Soudelor transformed into an extratropical cyclone. The physical mechanism for changes in the EASJ intensity and position caused by TC Soudelor is explored. Results indicate that TC Soudelor would warm the air in the middle and upper troposphere over the Japan Sea and the adjacent areas through stimulating northward propagating teleconnection pattern as well as releasing large amounts of latent heat, which led to increase (decrease) the meridional air temperature gradient to the south (north) below the EASJ axis. As a result, the geopotential height abnormally increased in the upper troposphere, resulting in an anomalous anticyclonic circulation belt along the EASJ axis. Correspondingly, the westerly winds to the north (south) of the EASJ axis intensified (weakened) and the EASJ axis shifted northward by one degree. The case study also suggests that before the extratropical cyclone transition of TC Soudelor, the TC activities had exerted significant impacts on the EASJ through thermodynamic processes.

Flexible strain sensors, as the core member of the family of smart electronic devices, along with reasonable sensing range and sensitivity plus low cost, have rose a huge consumer market and also immense interests in fundamental studies and technological applications, especially in the field of biomimetic robots movement detection and human health condition monitoring. In this paper, we propose a new flexible strain sensor based on thick CVD graphene film and its low-cost fabrication strategy by using the commercial adhesive tape as flexible substrate. The tensile tests in a strain range of ~30% were implemented, and a gage factor of 30 was achieved under high strain condition. The optical microscopic observation with different strains showed the evolution of cracks in graphene film. Together with commonly used platelet overlap theory and percolation network theory for sensor resistance modeling, we established an overlap destructive resistance model to analyze the sensing mechanism of our devices, which fitted the experimental data very well. The finding of difference of fitting parameters in small and large strain ranges revealed the multiple stage feature of graphene crack evolution. The resistance fallback phenomenon due to the viscoelasticity of flexible substrate was analyzed. Our flexible strain sensor with low cost and simple fabrication process exhibits great potential for commercial applications.

The present work have been developed the interpretation processor including the behavior of material failure and the separation phenomena under transient dynamic loading (the operation of explosive bolt) using AUTODYN V4.3, SoildWork 2003 and TrueGrid V2.1 programs. It has been demonstrated that the interpretation in ridge-cut explosive bolt under dynamic loading condition should be necessary to the appropriate failure model and the basic stress of bolt failure is the principal stress. The use of this interpretation processor developing the present work could be extensively helped to design the shape and the amount of explosives in the explosive bolt having a complex geometry. It is also proved that the interpretation processor approach is an accurate and effective analysis technique to evaluate the separation mechanism in explosive bolts.

무선 센서 네트워크(Wireless Sensor Network)는 낮은 배터리, 짧은 통신거리 등의 제한된 센서들의 성능에 기인하여 내부자공격(insider attacks)에 취약한 것으로 알려져 있는데, 내부자 공격에 대응하기 위한 대표저인 방법으로 노드들의 행위 관찰하여 신뢰도를 평가하고 낮은 신뢰도를 갖는 노드들을 제거하는 신뢰메커니즘(Trust Mechanism: TM)이 있다. TM은 평가노드 자신의 직접관찰 정보뿐만 아니라 이웃노드의 간접관찰 정보를 함께 고려하도록 발전되어 왔는데, False-Praise 공격은 의도적으로 거짓 관찰 정보를 평가노드에게 제공하여 TM의 신뢰도 평가 프로세스의 신뢰성을 훼손하는 지능적 공격이다. 본 논문에서는 False-Praise 공격에 대응을 위한 합의 알고리즘을 기반의 개선된 TM 제안하고, 실험을 통해 제안 체계의 성능과 효과를 검증한다.
