본 논문에서는 Arduino의 I2C 통신을 통해 인터랙티브한 악기를 제안한다. 각각의 큐브는 서로를 인식하고 인식 후 집단이 된 큐브들은 하나의 악기가 된다. Arduino의 통신 핀을 알루미늄 호일에 연결하여 다른 큐브와 접촉 시 통신이 될 수 있도록 하였다. 통신이 이룬 큐브들을 rgbLED 색상 변화를 통해 시각적으로 접촉/비접촉을 나타냈다. 또한 Processing을 통해 그룹이 된 큐브들의 악기 소리를 제어하였다.

인간의 주관적이고 애매한 감성은 차세대 컴퓨팅의 다양한 분야에서 연구되며. 인간의 감성을 이해하고 감성의 변화에 능동적으로 반응하는 사용자 중심의 정보 처리에 대한 요구가 급격히 증가하고 있다. 우리는 감성기반 이미지 검색을 위해 저차원 시각정보에 대한 강성처리를 연구하고 있다. 기존의 저차원 시각정보 특징을 고려한 내용기반 이미지 검색 방법은 사용자의 취향이나 감성 요구에 적합한 결과를 검색하기에는 많은 어려움이 있다. 본 논문에서는 인간의 감성을 이해, 검색, 인식하기 위한 시각정보와 감성간의 관계 연구 중 우리의 기존 연구인 시각적 형태 정보의 감성어휘 공간에서 형태와 어휘간의 감성거리를 이용한 분류방법을 제안한다. 그리고 분류된 각 영역에서의 대표 어휘를 추출하여 시각적 형태에 따른 감성어휘간의 구체적 계층 관계를 정의한다. 이는 감성기반 이미지 검색 분야에 활용 가능한 연구이며, 우리가 사용하는 언어에 내재된 감성정보를 해석하고 그 어휘들의 체계적인 시각적 감성관계를 정의하는 의의를 갖는다.

As serious consequences of climate change became indisputable, vehicles based on fossil fuel has to be shifted toward more sustainable way to drastically reduce carbon emissions. Eco-friendly vehicles contribute mitigating climate change through reducing the greenhouse gas emissions. The goal of this research is to find ways to promote the eco-friendly vehicle industry in Korea. In order to achieve this goal, surveys are collected from the professionals of eco-friendly vehicle industry, and analyzed through Delphi method. Results show that the first thing is to promote the eco-friendly vehicle market by introducing the economic incentives. The second thing is to allow more emission credit for eco-friendly vehicle manufacturers. The third thing is to build more concrete infrastructure for the eco-friendly vehicles. The increase of the number of the electric or hydrogen charging system would be one of the good examples of the infrastructure. The fourth thing is that the government supports the research & development of eco-friendly vehicles. The fifth is to regulate that the government agency is mandatory to use the eco-friendly vehicles. The sixth thing is to provide the low-carbon certification for eco-friendly vehicles. The seventh thing is to support advertising the eco-friendly vehicles. The results from this research can be used as a guideline to make policies to stimulate the eco-friendly vehicle industry in Korea.

Korea has introduced Korea Emissions Trading Scheme (Korea ETS) since 2015. However, not many companies voluntarily participate in the emissions trading. The goal of this paper is to provide the way to improve the Korea ETS. This study compares the Korea ETS with EU Emissions Trading System, which has been practiced for a decade, and suggests three strategies to activate the Korea Emissions Trading Scheme. The first thing is to encourage more companies to participate in the emissions trading since the number of companies in the emissions trading in Korea is quite limited compared with that of EU. The second thing is to activate the trading of Korean Credit Unit in order to stimulate various emission reduction mechanisms. Currently, the most of the trading in the emissions market is through the Korean Allowance Unit. The third thing is to establish concrete measures to continuously improve the Korea ETS. A comprehensive evaluation of the Korea ETS is needed along with the ongoing convergence with the associated comments. The improvement of Korea ETS would be one of the most efficient ways to compete the climate change, and would also play a role to raise the status of Korea.

This study is to present a fainting motion recognizing method by using fish-eye lens images to sense emergency situations. The camera with fish-eye lens located at the center of the ceiling of the living room sends images, and then the foreground pixels are extracted by means of the adaptive background modeling method based on the Gaussian complex model, which is followed by tracing of outer points in the foreground pixel area and the elliptical mapping. During the elliptical tracing, the fish-eye lens images are converted to fluoroscope images. the size and location changes, and moving speed information are extracted to judge whether the movement, pause, and motion are similar to fainting motion. The results show that compared to using fish-eye lens image, extraction of the size and location changes. and moving speed by means of the conversed fluoroscope images has good recognition rates.

The purpose of this study is to understand how a teacher's teaching can be changed while he or she teaches the same contents in different classes. The qualitative research method was used in this study. Data were collected from classroom observations, several in-depth interviews, and stimulated-recall interviews after each class. All the data were transcribed and analyzed interpretively, and then, the results of the analysis were checked by each participating teacher. The results are as follows: First, changes appeared in each class in terms of the teaching items, tools, sequence, and time, even though the same teacher taught the same contents. It showed that the teacher's teaching practice changed immediately and intuitively in class. Second, teachers tried to implement "exploratory teaching" or "move-testing teaching" to address the emerging problems during their teaching. They then reflected on and modified their own teaching. This type of change, which happened during the teaching practice, can be an example of "Reflection-in-practice." Thus, the results of this study can provide helpful insights into how teachers might adapt and reflect in their teaching. It suggests that teachers need to recognize their subconscious teaching changes and learn "Reflection-in-practice."

The purpose of the case study is to understand changes in the teaching practices of two secondary science teachers during the span of their careers. To investigate changes in teaching practices, this study focuses on changes in the science teachers' practical principles based on Elbaz's practical knowledge. The biographical approach was adopted because teachers' voices are a valuable source to understand their professional development. In-depth interviews and classroom observations were conducted for two science teachers with seven years' and ten years' teaching experience. The major findings are as follows: First, participants' teaching practices changed through interaction with three factors, critical experiences that have stirred changes in teaching practice, teacher's reflection on teaching, and various experiences to make specific teaching practice changes. Second, three different change aspects of practical principles were revealed; reinforcement of existing practical principles, replacing old practical principles with new one, and generation of new practical principles.

This paper proposes a method to detect fall action by using stereo images to recognize emergency situation. It uses 3D information to extract the visual information for learning and testing. It uses HMM(Hidden Markov Model) as a recognition algorithm. The proposed system extracts background images from two camera images. It extracts a moving object from input video sequence by using the difference between input image and background image. After that, it finds the bounding rectangle of the moving object and extracts 3D information by using calibration data of the two cameras. We experimented to the recognition rate of fall action with the variation of rectangle width and height and that of 3D location of the rectangle center point. Experimental results show that the variation of 3D location of the center point achieves the higher recognition rate than the variation of width and height.
