The purpose of this study was to investigate whether the mirror environment influences the attitude of the client when counselling. A group of 16 experimenters, 16 controls, a group with a mirror environment, and 32 men and women according to the presence or absence of interventional mirror environments in the control group. There was a statistically significant difference in the 'self - alienation' factor of the Authentic Scale(AS) in the experimental group that provided the mirror environment. There was no significant difference in the Semantic Differential Scale(SDS) between the experimental group and the control group. This study was conducted to investigate whether the presence of the mirror environment affects the client 's authenticity. There were significant differences in some of the factors of the Authentic Scale.

With the emergence of Brain-Computer Interface (BCI) technology, analyzing mirror neurons has become more feasible. However, evaluating the accuracy of BCI systems that rely on human thoughts poses challenges due to their qualitative nature. To harness the potential of BCI, we propose a new approach to measure accuracy based on the characteristics of mirror neurons in the human brain that are influenced by speech speed, depending on the ultimate goal of movement. In Chapter 2 of this paper, we introduce mirror neurons and provide an explanation of human posture estimation for mirror neurons. In Chapter 3, we present a powerful pose estimation method suitable for real-time dynamic environments using the technique of human posture estimation. Furthermore, we propose a method to analyze the accuracy of BCI using this robotic environment.

As the economic growth achieved and the straight road was increased. so, the tunnel built more than before. In these days, lighting of tunnel entrance is important for safety and comfortable driving. Most of the tunnel lighting depend on artificial lighting and they use a lot of energy. In this paper, as a research for illumination improvement and saving energy at tunnel, reflecting mirror system is suggested. The performance of the system was evaluated with respect to various aspects. By applying a reflective mirror system, tunnel lighting and environment can be improved. This study is a preliminary study for developing a system to save energy of tunnel artificial lighting.

자연채광은 실내공간의 쾌적성을 향상시키며, 재실자의 건강을 증진시킬 뿐만 아니라 에너지 절약적인 측면에서 시너지 효과를 발휘하고 있다. 이에 반사거울형 태양광채광시스템은 도시가 과밀하고 고층화됨에 따라 자연채광의 도입이 어려운 실내공간에 태양광을 도입할 수 있는 자연에너지 활용장치라 할 수 있다. 본 연구는 태양광채광시스템을 이용하여 주거건물 옥상에 1차반사거울을 설치하고, 반지하의 상부에 2차반사거울을 설치하여 거실공간에 태양광을 유입하였다. 시스템 미설치시와 설치시에 대한 거실의 바닥면조도와 외부조도를 동시에 측정하여 외부조도에 대한 내부조도의 비율인 주광조도비를 분석하고, 증감율을 구하여 반사거울형 태양광채광시스템의 성능을 평가하였다. 채광성능평가 결과 채광시스템의 설치로 인한 실내 주광조도비는 평균 $80{\sim}1,400%$정도 증가하는 것으로 나타났으며, 또한 창면부에 비해 실의 후면부가 2배 이상 증가한 것으로 나타나 채광성능이 매우 큰 것으로 나타났다. 따라서 본 연구에서 실험한 반사거울형 태양광 채광시스템은 주거건물에서의 적용이 용이하고 높은 채광성능을 제공할 수 있어 실내 빛환경 향상에 크게 기여할 수 있을 것으로 기대된다.

In order to acquire hydraulic characteristics for unsaturated layers, water retention tests were performed and compared by using the evaporation method, volumetric pressure plate extractor (VPPE) and chilled-mirror dew point method. The evaporation and chilled-mirror method are currently developed experimental technology and measure the water retention curve of unsaturated soils quickly and accurately. In the evaporation and VPPE method, the water retention has been measured and compared until 100kPa matric suction and consequently the result of the evaporation method could be verified. In the chilled-mirror method, the water retention has been measured until high level of matric suction and the overall shape of water retention curves could be obtained. As a result of water retention tests, the representative water retention curves were obtained and the applicability of each test method was discussed. Using both the evaporation and chilled-mirror methods, the soil water retention curve can be acquired reasonably for the whole range of matric suction.

Researchers have developed virtual reality environments to provide audience with more visually immersive experiences than previously possible. One of the most popular solutions to build the immersive VR space is a multi-projection technique. However, utilization of multiple projectors requires large spaces, expensive cost, and accurate geometry calibration among projectors. This paper presents a novel omnidirectional projection system with a single projector and a single spherical mirror.We newly designed the simple and intuitive calibration system to define the shape of environment and the relative position of mirror/projector. For successful image projection, our optimized omnidirectional image generation step solves image distortion produced by the spherical mirror and a calibration problem produced by unknown parameters such as the shape of environment and the relative position between the mirror and the projector. Additionally, the focus correction is performed to improve the quality of the projection. The experiment results show that our method can generate the optimized image given a normal panoramic image for omnidirectional projection in a rectangular space.

Although service robots in various fields are being commercialized, most of them have problems that depend on explicit commands by users and have difficulty to generate robust reactions of the robot in the unstable condition using insufficient sensor data. To solve these problems, we modeled mirror neuron and theory of mind systems, and applied them to a robot agent to show the usefulness. In order to implement quick and intuitive response of the mirror neuron, the proposed intention-response model utilized behavior selection networks considering external stimuli and a goal, and in order to perform reactions based on the long-term action plan of theory of mind system, we planned behaviors of the sub-goal unit using a hierarchical task network planning, and controled behavior selection network modules. Experiments with various scenarios revealed that appropriate reactions were generated according to external stimuli.

To lead lighting inside, design solution and mechenical solution can be used.A inner court and atrium are samples for design solution. However, physical and environmental elements for building design are not taken positively into consideration. So low position of the inner court is difficult to reach lighting performance and a urban landscape gets damaged. On this study, selecting a building with a inner court, best design method is suggested to apply reflecting mirror. building direction, building shape and solar position are considered to deside the setting angle for reflecting mirror. Performance for the setting reflecting mirror is verified through various simulation cases, and is got more lighting performance than the present situation on the building inside.

Sample cosmetics used in cosmetics department in a situation where an infectious disease problem arises due to the emergence of COVID-19 can be a cause of infection. To prevent this, each cosmetic store can use a Beauty Mirror. The Beauty Mirror is composed of an operation device and a mirror device. In order to recognize the user's face in the mirror device, the feature points of the face are searched and the feature points are divided and used for each part. For communication between the operation device and the mirror device, data is transmitted and received through Serial communication using the FTDI232 chip. Beauty Mirror is not limited to cosmetics department, but can be applied to online shopping malls to enable testing in an online environment.
