Based on the perception of Maurice Merleau Ponty, This study defines that Moving is a form lively to experience meaning, pleasure as the aesthetic attribute structured to a product, expression and value are synthesized into. The purpose of study is to argue that Wearable, Ubiquitous, Interaction, Play, D, I, Y, Universal, Ecology are the forms, modalities that the moving is variously subjected to the product design. Above This is the result reasoned according to analogical form as below between the moving and all design forms. First, The moving as the aesthetic expression and value are synthesized into is the intrinsic, general proposition, maxim for the value judgement. Second, All design forms are the cases which the values based on the aesthetic expression system are subjected to Third, Thus All design forms are the modalities of the aesthetic expression based on the values. The certainty of this judgement, reasoning is the proof that the correspondence between the moving as the aesthetic expression and design form is the fact. That is to say, It is the proof that Users lively experience the aesthetic meaning, pleasure in fact as the aesthetic values are subjected to all design forms. The lived experience of each user in their daily life itself is the only method or assurance for this. The moving integrates the existence of a product and what should be of users into the aesthetic dimension and at the same time, is realized based on this. The emphasized theme in all cases of this study is not the product but the moving. So, The product design is changed into the action which structures the moving like above to a product.

본 논문은 자위권 사용과 군사력 사용 간의 관계를 분석하고 이를 한반도 서해에서의 한국과 북한 간 해상긴장 상황에 적용시킨 이슈를 다룬다. 국가가 행사하는 자위권(self-defense: 自衛權)은 기본적으로 전쟁 방지를 위한 기본적 원칙이다. 그러나 이는 군사력 사용(Use of Forces: 軍事力 使用) 또는 무력행사(武力行事)이라는 측면에서 칼의 양날과 같은 결과를 낳는다. 즉 자위권 행사로 전쟁의 확산을 방지하는 반면에 자위권 행사로 상대방에 대한 적성(敵性)을 인정해 주는 경우이다. 반면 북한의 군사도발은 전방향적이며, 1953년 한반도 정전협정 위반이다. 1953년 정전협정 체결 이후 양국은 서해 북방한계선(NLL)에서의 군사적 충돌을 거쳤으며, 이는 과연 한국이 자위권 차원에서의 방어태세와 군사력 사용 측면에서의 대응태세 간에 괴리가 존재하고 있다는 것으로 나타나고 있다. 당연히 피해를 받는 곳은 한국이며, 이는 서해 북방한계선에서의 남북한 해군 간 대결국면에서 나타나고 있다. 이에 본 논문은 자위권을 국가 차원 행사하는 수준과 작전에 투입된 현장 작전 지휘관 차원에서 행사하는 수준으로 구분하여 다룬다. 서해 북방한계선 부근 수역에서의 북한의 해상 군사도발에 대해 현장 작전 지휘관이 행사하는 자위권은 대한민국 정부 차원에서의 자위권 행사와는 다르면, 이 문제를 국제법을 중심으로 분석하기에는 너무나 많은 제한점이 있다. 현행 국제법상 국가 자위권 문제는 군사력을 동반하는 문제로서 그 행사요건이 매우 애매모호하고 까다롭다. 그러나 현장 작전지휘관의 자위권 행사는 단호해야 하며, 이는 군사력 운용으로 나타나야 한다. 실제 서해에서의 남북한 대결국면에서의 대한민국 해군의 자위권 행사는 정전협정에 의거 제한되고 있으며, 이는 2010년 북한의 천안함 침몰과 연평도 폭격도발 시 대한 민국 해군과 해병대의 대응에서 증명되었다. 현재 대한민국 국방부는 현장 작전 지휘관에서 소위 '선제적 자위권 행사' 부여 필요성에 대한 논의를 진행 중으로 알려져 있다. 이에 따라 선제적 자위권 행사를 위한 조치들을 제도화하는 움직임을 보이고 있다. 예를 들면 2013년 발표된 대한민국 합참과 유엔사령부/한미 연합사령부/주한미군사령부 북한 군사 도발에 대한 대응계획(ROK JCS and UNC/CFC/USFK Counter-Provocation Plan)이 이를 간접적으로 증명하고 있다. 선제적 자위권은 행사에 있어 몇 가지 원칙을 요구하고 있으며, 이에 대한 합법성 문제는 아직 해결되고 있지 않다. 따라서 이 문제와 북한 군사도발 시에 대한 대한민국의 선제적 자위권 행사 간 연관성 문제를 어떻게 해석할 수 있는가에 대한 연구가 필요한 실정이다. 평시 군사력 사용에 따른 무력행사의 적법성은 그 인정이 대단히 어려운 것이 현실이며, 이에 따라 북한의 군사도발에 대한 가장 효율적 방안이 선제적 자위권이라면, 이에 대한 법적 대응이 무엇인가에 대한 제도적 근거를 필요로 할 것이다.

Generally a return current plane(RCP) of high speed digital and analog part is partitioned. This is achieved in order to decrease the noise interference between subsystem in PCBs(Printed Circuit Boards). However, when the connected signal line exists between each subsystem, this partition will cause unwanted effects. In a EMI(Electromagnetic Interference) point of view, the partition of the return current plane becomes a primary factor to increase the radiated emission. Component bridge(CB) is used for the way of maintaining radiated emission, still specific user's guide doesn't give sufficient principle. In a view point of EMI, design principle of multi-CB using method will be analyzed by measurement. And design principle of noise mitigation will be provided. Generally interval of multi-CB is ${\lambda}/20$ ferrite bead. In this study, When multi-CB connection is applied, design principle of ferrite bead and chip resistor is proved by measurement. Multi-connected chip resistance$(0{\Omega})$ is proved to be more effective design method in the point of EMI.

Generally a return current plane(RCP) of high speed digital and analog part is partitioned. This is achieved in order to decrease the noise interference between subsystem in PCBs(Printed Circuit Boards). However, when the connected signal line exists between each sub system, this partition will cause unwanted effects. In a circuital point of view, RCP partition has a bad influence upon signal integrity. In a EMI(Electromagnetic Interference) point of view, the partition of the return current plane becomes a primary factor to increase the radiated emission. Component bridge(CB) is usecl for the way of maintaining signal integrity, still specific user's guide doesn't give sufficient principle. In a view point of signal integrity, design principle of multi-CB using method will be analyzed by measurement and simulation. And design principle of noise mitigation will be provided.

This study aimed to examine how video-recorded hearsay statements are taken in trial with regard to testimony of children less than the age of 13 in terms of children's rights, and to assess policy implications for the purpose of improving the current system. This study analyzed the precedents in accordance with their facts and contents. The analysis of the contents dealt with the main issues of trials concerning the sexual violence of children less than the age of 13. Specifically, This study selected precedents dealing with video-recorded hearsay statements, which are children's indirect statement, as core legal issues; examined the credibility(probative power) and admissibility of video-recorded statements; and prepared systemic alternatives in accordance with the United Nations Convention on the Rights of the Child, the international standards for the protection of children's rights. As a result, this study proposed creating and utilizing indicators to assess evidence admissibility and the credibility of video-recoded statements in trial, thus reducing judgement through judges' discretion. Also proposed are new regulations with regard to cross-examination coverage of the hearsay statement of a child in a sexual violence trial of concerning children less than the age of 13. This study suggests an improvement in legal policies, based given that children's rights are more vulnerable than those of adults in trial. Nevertheless, this study is limited in that it selected and reviewed only among precedents that are in the public record.

In general, the presence of non-selective intercrystalline (grain boundary) defects in polycrystalline metal-organic framework (MOF) or zeolite membranes, which are known to be ca. 1 nm in size, causes lower membrane performance (selectivity) than the intrinsically expected. In this study we show that applying a thin polymeric coating of polydimethylsiloxane (PDMS) on a polycrystalline MOF membrane is effective to cap the non-selective intercrystalline defects and therefore improve membrane performance. To demonstrate the concept, first, polycrystalline UiO-66, one of Zr-based MOFs, membranes were prepared by an in-situ solvothermal growth. By controlling membrane growth condition with respect to growth temperature, we were able to obtain polycrystalline UiO-66 membranes at 150 ℃ with intercrystalline defects of which the quantity is not significant, so it can be plugged by the suggested PDMS deposition. Second, their performances were compared before and after the PDMS deposition. As expected, the PDMS deposition ended up with a noticeable increase in CO₂/N₂ ideal selectivity from 6 to 14, indicating successful intercrystalline defect plugging. However, the enhancement in CO₂/N₂ selectivity was accompanied by a significant reduction in CO₂ permeance from 5700 to 33 GPU because the PDMS deposition not only plugs defects but also forms a continuous coating on membrane surface, adding an additional transport resistance.

This paper is concerned with the query slipping and its prevention for trajectory-based matchmaking service in wireless sensor networks. The problem happens when a query propagating along a subscribe trajectory moves through a publish trajectory without obtaining desired information, even though two trajectories intersect geometrically. There follows resubmission of the query or initiation of another subscribe trajectory Thus, query slipping results in considerable time delay and in the worst, looping in the trajectory or query flooding the network. We address the problem formally and suggest a solution. First, the area where nodes are distributed is logically partitioned into smaller grids, and a grid-based multicast next-hop selection algorithm is proposed. Our algorithm not only attempts to make the trajectory straight but also considers the nodal density of recipient nodes and the seamless grid-by-grid multicast. We prove that the publishing and subscribing using the algorithm eventually eliminate the possibility of the slipping. It toms out that our algorithm dissipates significantly less power of neighbor nodes, compared to the non grid-based method, as greedy forwarding, and the fixed- sized grid approach, as GAF (Geographical Adaptive Fidelity)

RSA-CRT algorithm is widely used to improve the performance of RSA algorithm. However, it is also vulnerable to side channel attacks like as general RSA. One of the power attacks on RSA-CRT, proposed by Boer et al., is a power analysis which utilizes reduction steps of RSA-CRT algorithm with equidistant chosen messages, called as ECMPA(Equidistant Chosen Messages Power Analysis) or MRED(Modular Reduction on Equidistant Data) analysis. This method is to find reduction output value r=xmodp which has the same equidistant patterns as equidistant messages. One can easily compute secret prime p from exposure of r. However, the result of analysis from a reduction step in [5] is remarkably different in our experiment from what Boer expected in [5]. Especially, we found that there are Ghost key patterns depending on the selection of attack bits and selected reduction algorithms. Thus, in this paper we propose several Ghost key patterns unknown to us until now, then we suggest enhanced and detailed analyzing methods.

This paper proposes an image segmentation for a vision-based automated defect inspection system on surface image of TFT-LCD(Thin Film Transistor Liquid Crystal Display) panels. TFT-LCD images have non-uniform brightness, which is hard to finding defective regions. Although there are several methods or proposed algorithms, it is difficult to divide the defect with high reliability because of non-uniform properties in the image. Kamel and Zhao disclosed a method which based on logical stage algorithm for segmentation of graphics and character. This method is a one of the local segmentation method that has a advantage. It is that characters and graphics are well segmented in an image which has non-uniform property. As TFT-LCD panel image has a same property, so this paper proposes new algorithm to segment regions of defects based on Kamel and Zhao's algorithm. Our algorithm has an advantage that there are a few ghost objects around the defects. We had experiments to prove performance in real TFT-LCD panel images, and comparing with the FFT(Fast Fourier Transform) method which is used a bandpass filter.
