In an event of an emergency, such as fire in a building, visually impaired and blind people are prone to exposed to a level of danger that is greater than that of normal people, for they cannot be aware of it quickly. Current fire detection methods such as smoke detector is very slow and unreliable because it usually uses chemical sensor based technology to detect fire particles. But by using vision sensor instead, fire can be proven to be detected much faster as we show in our experiments. Previous studies have applied various image processing and machine learning techniques to detect fire, but they usually don't work very well because these techniques require hand-crafted features that do not generalize well to various scenarios. But with the help of recent advancement in the field of deep learning, this research can be conducted to help solve this problem by using deep learning-based object detector that can detect fire using images from security camera. Deep learning based approach can learn features automatically so they can usually generalize well to various scenes. In order to ensure maximum capacity, we applied the latest technologies in the field of computer vision such as YOLO detector in order to solve this task. Considering the trade-off between recall vs. complexity, we introduced two convolutional neural networks with slightly different model's complexity to detect fire at different recall rate. Both models can detect fire at 99% average precision, but one model has 76% recall at 30 FPS while another has 61% recall at 50 FPS. We also compare our model memory consumption with each other and show our models robustness by testing on various real-world scenarios.

본 연구는 연극을 전공하는 대학생들을 다양한 문제점(한정된 자기개발, 불안정한 정서인식 등)의 관점으로 바라보며 이 관점을 댄스스포츠를 체험을 통한 개선에 초점을 두었다. 연구의 방법은 실제사례를 통한 참여자들의 심층면담을 통하여 결론을 제시하였다. 결과로는 첫째. 움직임을 하면서 신체에 대해 이해하며 그것을 기준으로 움직임을 다양하게 사용할 수 있다. 둘째, 자신의 감정 상태를 이해할 수 있었고, 자기개발 및 스스로를 평가할 수 있는 능력이 생기게 되었다. 셋째, 외적으로는 디테일한 연기력을 갖추게 되었고 특히 시선처리에 있어서 구체적인 표현을 할 수 있었다. 또한 한정적인 움직임과 특기에서 벗어나 다양한 특기를 체험함으로써 자신감을 키울 수 있었다. 넷째, 댄스스포츠에 대한 부정적인 인식에서 벗어나 긍정적인 인식을 갖고 체험할 수 있었다. 다섯째, 연기의 표현방식과 댄스스포츠의 표현방식을 굉장히 유사하다.

화재감지 및 경보시스템의 설계 목표는 화재발생 초기 단계에서 화재징후를 발견, 피난의 개시를 신속하게 통수하는 것이다. 화재감지기는 다양한 건물 및 환경에 설치되기 때문에 주위 온도 및 가연물의 종류 등 환경적 측면을 심층적으로 고려하지 않으면 적절하게 감지하지 못하는 경우가 발생할 수 있다. 즉, 가연물 종류 등을 고려한 설계에 따라 설치된 화재감지기는 화재시 설계치 대로 조기에 화재를 감지하여 화재 예방 및 화재로 인한 피해를 최소화할 수 있는 것이다. 본 논문은 화재시 조기에 화재를 감지기하여 건축물내 인명피난을 목적으로 설치되는 화재감지기의 응답특성을 분석한 연구이다. 화재감지기의 응답특성을 분석하기 위하여 다양한 가연물을 발생시키고 화재감지기 종류별로 설치한 다음 각 화재감지기의 응답특성을 분석하였다. 그 결과 정온식 열감지기는 열방출률이 적은 화재를 조기에 감지하는 것에 적합하지 않은 것으로 나타났다. 광전식 연기감지기는 회색 계통의 목재류 화재성상에서 응답특성이 떨어졌고, 동일한 공간에서 화원의 수평거리와 동작시간이 비례한다고 볼 수 없었다.

Arne Naess' ecocentrally-oriented worldview of 'Self-realization' has been continually attacked by sociocultural critics since it was launched in the early 1970s. Especially ecofeminists and social ecologists criticize that the concept of Self-realization cannot accept social & cultural particularity enough. In other words, they assert that Deep Ecology cannot efficiently resist interpersonal hierarchy. Concentrating their criticism on compassion just for nonhuman beings, the interpersonal equality-oriented critics claim that Deep Ecology should incorporate voices of marginalized humans within their eco-centered world view. Even if Naess recently recognizes necessity to draw more attention to sociohistorical particularity, still unchanged remains essentialism in his neological term 'Self-realization.' Compared to exclusiveness in Naess' Self-realization, the Buddhist worldview of Interdependent Arising(pratityasamutpada) favors both intraspeciel egalitarianism and interpersonal equality as well. The very insight that all beings dependently co-originate reasons compassion for historically marginalized humans as well as nonhuman beings. Accordingly, today's environmentalism might better its efficiency as it goes toward the inclusive Buddhist world view of interdependent arising. For the human being tends to respond more readily to his or her individually urgent problems than their remote social matters.

This study was performed to explore the institutional treatment system by analyzing the pattern of musical actor's projection and aftereffect subsequent to the completion of performance. In-depth interviews were conducted with 22 top-class musical actors and actresses of the Republic of Korea. The result of the survey indicated that most actors and actresses suffer from projection and it's aftereffect such as depression for more than one month after performance, and that they tend to rely on self-healing based on self-diagnosis rather than seeking for professional counselling. The symptoms of projection were shown more strongly when the actors or actresses were taking on the role of main character, or acting as a negative or realistic character, or when expressing strong and extreme emotions. In this era of Korean culture, the result of this study implies that our country have to establish the actor's mental caring-related new law and private care centers supported enough funds to encourage the actors to receive more effective actor-friendly treatment service before and after the performance.

With the help of information technology for a film, characteris both the composition of the story and one of the most important elements that lead the story. Character has a close relationship with personality description, and the character's age, background, education, and occupation help decide his or her personality. Charades are important in that by describing a character's psychology using charade techniques, it gives a stronger impression than by describing with merely lines or narration. When a man's thought changes, their behavior changes; when a behavior is repeated, it becomes habit; when a habit is repeated, it becomes nature. The nature is the person's personality, otherwise called character. Therefore, charade techniques describe a character's psychology well, and consequently, it has maintained its importance. Because human nature and in-depth psychological description have a connection with a character's personality development, I would like to discuss the topic through this research. By using Director Shunji Iwai's "April Story" as the text, the effects of charade techniques on a character's personality development in film will be analyzed by seeking and presenting the methodology shown within the work through charade-acting techniques used by the characters for the development of character's personality.

The Plays of Kang Yang Won and the Theatre Troupe Dong don't aim to use the body as a system of sign in order to express the mind. They want to show the physical presence of an actor which induces sensuous perception of audience, so the possibility of the aesthetics of performativity can be open. Therefore, the properties of body sound and space have important meaning. At the same moment the body of audience has to be open to the perception. It means that the audience has to be ready to perceive the energy breathing density and tension etc. which the body of actor causes. As a result, the audience experiences a simultaneous opening of consciousness and perception: simultaneous opening of consciousness and perception gives the chance of receiving the emergent meaning.

The purpose of this paper is to study on the elements of the Sinmyung and the expression recognition of body movement in Korean dance of college students majoring in musical. The participants were 12 male and female college students in musical major who experienced in dance, song and acting. The program was composed of the experience of the Sinmyung: recognition of sound and dance, breathing and movement in the Korean dance, 8 hours twice a week for four weeks. As a qualitative approach is the discovery of the center of the process, we carried out an inductive analysis of the area on the basis of observation, in-depth interview and student report. The core of this analysis is to attempt to analyze contents concentrating on the recognition exploration of the Sinmyung sentiment and the body expression through sound and breathing. In conclusion, for college students majoring in musical, the expression recognition of the experience of the Sinmyung and the movement in the Korean dance contributes to the improvement of creative thinking through body perception, and the practical use of the capacity of image expression through concentration of sound and breathing. Finally, the results of this research could articulate with the value of body expression and the creative factors of college students majoring in musical.
