Just as the front gate is located at the meeting point between the house and the street, the Subject and the Other face each other the same way. This study examines the relationship between House(subject) and Stree (other) at the boundary of the Front Gate-Face. Pursuing the aspects of the changing Front Gate-Face accordingly to the attitude of the Subject facing the Other, this study tries to analyze the possibilities and significance of the hospitality Front Gate-Face with the ethical point of view of Levinas. As architectural instance, results of examining the Front Gate-Face of traditional houses in Korea, China and Japan are as follows. Front Gate-Face of China is characterized by self-centered introversion to interact with the external world (the other). Front Gate-Face of Japan is characterized by a humble submission to the group. Front Gate-Face of Korea shows however more flexible relationship orientations in terms of hospitality, compared to Japan or China. When looking through hospitality factors, accordingly to the above mentioned Korean hospitality characteristics, the possibilities seem not be exclusively bordered inside the conceptual category perimeter suggested by Levinas' concept of hospitality. It is almost impossible for the nowadays ever-strong privacy culture to not allow room for the architectural structure of an absolute hospitality toward others. However, this impossibility not being absolute, still yields a space for a significant possibility to explore.

We did bench blasting upon the natural rock which it's uniaxial compressive strength was about $1,420~1,476kgf/\textrm{cm}^2$. This is the results we inferred after measuring, analyzing the ground vibration velocity of the front and back direction from the free face of the bench blasting. We have to induce the square and cube root scaled equation and the general equation to guarantee confidence upon the data when analyzing the measurement data of the test blasting. The variable distance is in reverse proportion to the permitted ground vibration velocity. The shorter is the exploding point to a protection structure, the bigger is the reflection that the direction of the free face experts the ground vibration velocity, The ground vibration velocity front of the free face tends become reduced about 38~46% compare with back of the free face in the range that the permitted ground vibration velocity is 2.0~5.0mm/sec. In case of 2.0mm/sec, when a protection structure is within about 95m, the max. allowable charge weight per delay on positing front of the free face can be more used about 2.61 times than that on positing back of the free face, in case of 3.0mm/sec within about 78m more about 2.38 times, in case of 5.0mm/sec within 60m more about 2.10 times. In case of 2.0~5.0mm/sec when a protection structure is within about 200m front from the free face, the max. allowable charge weight per delay can become about 1.52 times than the case on back to the free face.

Recently, 3D related technology has become a hot topic for IT. 3D technologies such as 3DTV, Kinect and 3D printers are becoming more and more popular. According to the flow of the times, the goal of this study is that the general public is exposed to 3D technology easily. we have developed a web-based application program that enables 3D modeling of facial front and side photographs using a mobile phone. In order to realize 3D modeling, two photographs (front and side) are photographed with a mobile camera, and ASM (Active Shape Model) and skin binarization technique are used to extract facial height such as nose from facial and side photographs. Three-dimensional coordinates are generated using the face extracted from the front photograph and the face height obtained from the side photograph. Using the 3-D coordinates generated for the standard face model modeled with the standard face as a control point, the face becomes the face of the subject when the RBF (Radial Basis Function) interpolation method is used. Also, in order to cover the face with the modified face model, the control point found in the front photograph is mapped to the texture map coordinate to generate the texture image. Finally, the deformed face model is covered with a texture image, and the 3D modeled image is displayed to the user.

Since Broms and Bennermark(1967) suggested the face stability criterion based on laboratory extrusion tests and field observations, the face stability of a tunnel driven in cohesive material has been studied by several authors. And recently, more general solution for the tunnel front is given by Leca and Panet(1988). They adopted a limit state design concept to evaluate the face stability of a shallow tunnel driven into cohesionless material and showed that the calculated upper bound solution represented the actual behavior reasonably well. In this study, two factors are simultaneously considered for assessing tunnel face stability: One is the effective stress acting on the tunnel front calculated by upper bound solution; and the other is the seepage force calculated by numerical analysis under the condition of steady state ground water flow. The model tests were performed to evaluate the seepage force acting on the tunnel front and these results were compared with results of numerical analysis. Consequently, the methodology to evaluate the stability of a tunnel face including limit analysis and seepage analysis is suggested under the condition of steady state ground water flow.

This paper introduces a real-time face swapping system that enables video influencers to swap their faces with arbitrary generated face images of their choice. The system is implemented as a Django-based server that uses a REST request to communicate with the generative model,specifically the pretrained stable diffusion model. Once generated, the generated image is displayed on the front page so that the influencer can decide whether to use the generated face or not, by clicking on the accept button on the front page. If they choose to use it, both their face and the generated face are sent to the landmark extraction module to extract the landmarks, which are then used to swap the faces. To minimize the fluctuation of landmarks over time that can cause instability or jitter in the output, a temporal filtering step is added. Furthermore, to increase the processing speed the system works on a reduced set of the extracted landmarks.

얼굴은 사람을 확인할 수 있는 고유한 성질을 갖고 있어 얼굴 인식이 출입통제, 범죄자 검색, 방법용 CCTV 같은 보안 영역과 본인 인증 영역에 활발히 활용되고 있다. 정면 얼굴 영상은 가장 많은 얼굴 정보를 갖고 있어 얼굴 인식을 위해 가능한 정면 얼굴 영상을 취득하는 것이 필요하다. 본 연구에서 하르유사 특징을 이용한 Adaboost 알고리즘을 이용해 얼굴 영역이 검출되고 mean-shift 알고리즘을 이용해 얼굴을 추적한다. 그리고 얼굴 영역에서 눈과 입 같은 얼굴 요소들의 특징점들을 추출해 그들의 기하학적인 정보를 이용해 두 눈의 비와 얼굴의 회전 정도를 계산하고 실시간으로 근사 정면 얼굴 영상을 제시한다.

얼굴 인식 시스템에서 어떤 인식 파라미터를 사용하느냐에 따라 그 시스템의 성공여부가 판가름난다. 일반적으로 얼굴영상은 조명 상태 등과 같은 주변 환경에 따라 인식 파라미터가 영향을 받는다. 이를 해결하기 위해서는 측면 영상은 주위의 휘도변화에 다소 둔감하므로 측면 영상에서 특징을 추출하여 정면 영상에서의 문제점을 보완하는 것이 올바른 접근 방식이라 여겨진다. 본 논문에서는 이같이 정면영상과 측면영상의 정보를 보완, 취합하는 방식을 제안하고자하며 이를 여러 가지 방법들과 비교, 고찰함으로써 본 논문의 유용성을 입증하고자 한다.

본 연구에서는 반구형과 평탄형의 비상체를 이용하여 일반콘크리트와 섬유보강콘크리트에 충격시험을 진행한 후 파괴깊이와 형태, 파괴직경, 배면의 인장변형을 평가하였다. 선단면적이 작을수록 충격력의 집중에 의해 파괴깊이는 크고 표면파괴 직경은 작게 되는 것으로 확인되었다. 반면에 선단면적이 클수록 파괴깊이는 작지만 표면파괴직경은 크게 되었다. 일반콘크리트와 섬유보강 콘크리트에서 유사한 표면파괴와 배면변형이 발생하였으나 인장변형의 크기는 일반콘크리트에 비해 섬유보강 콘크리트가 작은 것으로 나타났다. 또한, 비상체의 선단형상에 따른 표면관입의 형태와 배면의 인장변형 사이에 직접적인 연관이 있는 것으로 사료된다. 따라서 콘크리트의 배면박리한계두께 예측 시에는 표면관입깊이뿐만 아니라 배면의 변형거동 또한 고려할 필요성이 있을 것으로 사료된다.
