The 'Biomechanics', which was devised to systematically train actor's material and medium, is evaluated as the first approach to an acting method in earnest with Stanislavsky's 'System'. Especially, due to the psycho-physical features of 'Biomechanics' that helps an actor to master a mechanism of human being such as stimulus, impulse and reaction, it was valued as an alternative for a naturalistic acting method that was excessively focused on the actor's emotional expression. However, the 'Biomechanics' is not utilized with activity in a field of actor training in Korea compared with Stanislavsky's 'The Method of Physical Action' which has a similar starting point as the psycho-physical feature. It is because of a political reason that a study for Meyerhold was officially forbidden in Russia until the mid-twentieth century. It is also because of a limit that incorporeal features of the 'Biomechanics' could not but be explained only by publications, especially translation. In this sense, as part of seeking for a new alternative of acting methods in Korea, this study will explore a possibility of applying the 'Biomechanics' to the actual actor training field through correct understanding of it.

This study is a new proposal for the methods of actor training and role creation in the contemporary theater and an approach to the practical utilization of the performer, regarding the actor's 'presence' as the essence of living arts, a peculiarity of theater. As the method for this, this study sorts out Vakhangov and Mikhail Chekhov's elements of acting techniques and at the same time, allows an easier approach to the theoretical concept based on the performance records found in the developmental process. The magic realism and the technique of acting discussed in priority in this study emphasize the importance of the exploration and realization of artistic inspiration in everyday life, the actor's imagination and image, and unconsciousness as a method for creating new actors and diversifying their roles. When their common views are summed up, the goals to achieve include a study of a creative method in which outer form and inner truth are combined and the implementation of a new system for creating the individual actor's originality. This study would classify the similarities and differences found through this, reveal the limit of practical efficacy and propose it as a universal method for creating the roles, asking for the actor's voluntary training and active attitudes.

This researcher looked at the characteristics of "$N\bar{a}tya$ $\acute{s}\bar{a}stra$" acting techniques focused on body expressions and sought to utilize it as training method for modern actors. 'Body postponement as a symbol' is a key characteristic of "$N\bar{a}tya$ $\acute{s}\bar{a}stra$" acting techniques, and each facial expression, gesture, and movement performed by an actor has a specific meaning. Therefore, the study on "$N\bar{a}tya$ $\acute{s}\bar{a}stra$" has been treated as a major study mainly in the non-realistic expression style or the body-centered acting theory. Therefore, a study on "$N\bar{a}tya$ $\acute{s}\bar{a}stra$" acting techniques was mainly dealt with as a major research subject in the nonrealistic expression style or body-centered acting theory. This study, on the other hand, emphasized the importance of research on the utilization plan of actor training, which can be usually used in realistic plays as well as non-realistic plays. According to psychologists such as Damasio and Eckman, internal impulses can also be triggered through expressions and actions associated with emotions. In addition, not only acting through the actor's inner impulse, but also expression of the actor's faithful external emotion can trigger the emotion of the audience. Such a case can be a psychological basis that "$N\bar{a}tya$ $\acute{s}\bar{a}stra$" acting techniques, which defines rasa and expresses it physically, can be used as a methodology to enhance inner truth. Therefore, the study on the actor training utilizing ing "$N\bar{a}tya$ $\acute{s}\bar{a}stra$" can be applied as an effective approach in the study of contemporary acting theory which intends to integrate inner impulse and external expression.

In this paper, we propose a smoker recognition algorithm, detecting smokers in a video sequence in order to prevent fire accidents. We use description-based method in hierarchical approaches to recognize smoker's activity, the algorithm consists of background subtraction, object detection, event search, event judgement. Background subtraction generates slow-motion and fast-motion foreground image from input image using Gaussian mixture model with two different learning-rate. Then, it extracts object locations in the slow-motion image using chain-rule based contour detection. For each object, face is detected by using Haar-like feature and smoke is detected by reflecting frequency and direction of smoke in fast-motion foreground. Hand movements are detected by motion estimation. The algorithm examines the features in a certain interval and infers that whether the object is a smoker. It robustly can detect a smoker among different objects while achieving real-time performance.

This thesis interrogates the term a performer's 'spontaneity' as the key principle to approach and enhance contemporary performer's training and acting. Drawing on a number of problematic issues, this thesis particularly examines the paradigm of the subtle bodily movement inform the experience of a performer's spontaneity as embodied and understood in approaching and adapting through text analysis and action. The in-depth process of the relationship between a performer's action and the transformative effects, is central to understanding and adapting the key principle of acting/training that a specific text would pursue through a specific performance by means of what a performer must do on stage. Following the discussion of acting in training and rehearsal, this thesis argues the necessity of an alternative way(s) and model of the performer's work via how the performer's action is sincerely emerged from the moment-by-moment rather than the performer anticipates what comes in the next and therefore pretend to do/be something/someone. Expanding upon the assumptions mentioned above, this thesis provides some pragmatic and descriptive work(s) from the practitioners' concepts and approaches that invites us to reconsider the nature of acting and its adaptability for contemporary performers.

An actor should be well-trained at the natural breathing and phonation in order for a good diction. This thesis is focused on the breathing training method at the pre-phonation stage. The past research on the breathing and phonation training was generally for vocal music, yoga, or those which were approached by the medical view point, whereas there are not so many researches which are approached for an acting training even though it is quite important for actors. In addition, such researches have been given an overview of breathing, phonation and diction. Therefore, this thesis which is focused on the breathing training at the pre-phonation stage suggests the natural breathing training method through the imagination and image in the various situations which could exist in the drama.

In this paper, we propose a quadtree-based optimization technique that enables fast Super-resolution(SR) computation by efficiently classifying and dividing physics-based simulation data required to calculate SR. The proposed method reduces the time required for quadtree computation by downscaling the smoke simulation data used as input data. By binarizing the density of the smoke in this process, a quadtree is constructed while mitigating the problem of numerical loss of density in the downscaling process. The data used for training is the COCO 2017 Dataset, and the artificial neural network uses a VGG19-based network. In order to prevent data loss when passing through the convolutional layer, similar to the residual method, the output value of the previous layer is added and learned. In the case of smoke, the proposed method achieved a speed improvement of about 15 to 18 times compared to the previous approach.

Europeans experienced the horror and cruelty of war through the first and second World Wars. They began to raise fundamental questions and doubt about the preexisting World Order of God and humans leading to the birth of Existentialism. The Theater of the Absurd is one of the genres in theater resulting from the existentialist theories. The Theater of the Absurd has a format opposed to the traditional Realist Theater and emphasize the absurdity of human and society's existence. In particular, Fernando Arrabal who is a French Absurdist playwright, expressed the absurd human conditions using his unique forms and contents and his work 'Fando et Lis' depicts the absurdity of the adult world through the eyes of a child. Many unrealistic elements typical and inherent in the Absurdist plays are present in his work. Especially, the actors were required to apply not only the realistic acting approach but also to study and analyze characteristics of all Absurdist plays and internalize them based on the creative foundation of recreation. Then, they were asked to examine the characters' personality, emotions, and actions and think hard about creating an unrealistic action of voice and movements. This creative process by actors is a must in developing the reliable and trustworthy Absurdist acting.

화재란 사람의 의도에 반하거나 고의에 의해 발생하는 연소현상으로서 소화시설 등을 사용하여 소화할 필요가 있는 것을 말한다. 사람의 의도에 반한다고 하는 것은 과실에 의한 화재를 의미하며 화기취급 중 발생하는 실화뿐만 아니라 부작위에 의한 자연발화도 포함하며, 고의에 의한다고 하는 것은 일정한 대상에 대하여 피해발생을 목적으로 화재발생을 유도하였거나 직접 방화한 경우를 말한다. 연소현상이라 함은 가연성 물질이 산소와 결합하여 열과 빛을 내며 급속히 산화되어 형질이 변경되는 화학반응을 말한다. 소화시설 등을 사용하여 소화할 필요가 있다는 것은 화재란 연소현상으로서 소화의 필요성이 있어야 하며 소화의 필요성의 정도는 소화시설이나 그와 유사한 정도의 시설을 사용할 수준 이상이어야 한다. 화재원인조사란 발화부를 판단하고 화재에 이르게 된 발화원을 규명하며, 발화부로부터 연소확대된 경과를 조사하는 일련의 행위로서 화재원인조사시 가장 중요한 사항은 발화부 판단인 바, 이는 화재원인이 발화부에만 존재하기 때문이다. 최근에는 다양한 소재의 사용으로 인해 일단 화재로 진행될 경우 인명 및 재산상 피해가 증가하게 되어 있으며, 이로 인해 화재조사시 화학, 물리, 전기, 건축, 기계, 소방 등 다양한 지식과 화재현장에 대한 이해가 요구된다. 화재현장 조사시 발화부 판단의 과학적 접근은 매우 중요한 것으로서, 화재원인의 명쾌한 규명으로 책임한계 구분은 물론, 유사사고의 재발방지를 위한 연구가 필요하다. 본 연구에서는 기 발생한 화재사례에서 얻은 화재패턴을 분석하여 얻은 자료를 통해 발화부를 판단할 수 있는 조사방법을 다음과 같이 제시하였다. 1) 화재시 열전달과 화염확산 과정에서 건축구조물, 내장재, 집적물 및 각종 설치물의 구조, 재질 등에 따라 다양한 화재패턴을 형성하게 됨을 알 수 있다. 2) 화재패턴의 종류로는 화재플럼에 의한 삼각형, 주상, V, U 패턴 등이 있으며, 연소 생성물인 화염, 연기, 열 등에 의해 다양한 형태를 보임을 알 수 있다. 3) 위와 같은 결과를 종합하여 연소의 상승성, 불꽃 및 연기 흔적, 열에 의한 흔적 등에 의해 연소의 방향성을 알 수 있다. 4) 결국 화재현장에서 명확한 화재원인을 규명하기 위해서는 화재패턴에 의해 연소확대과정을 역으로 추적하여 발화부를 결정한 다음, 발화부내에서 화재원인을 찾아내야 할 것이다.

Purpose: The clinical and radiological results of patients with type 3 talar neck fractures treated with the anteromedial approach using medial malleolar osteotomy and large distractor were analyzed retrospectively. Materials and Methods: From March 2009 to August 2016, 12 patients with a type 3 talar neck fracture, who underwent the anteromedial approach using a medial malleolar osteotomy and large distractor and who could be followed-up for more than 12 months after the operation, were examined. The patients were examined for the presence of Hawkins signs by anteroposterior and lateral radiographs and osteonecrosis by magnetic resonance imaging (MRI) on the postoperative 3 months. Subsequently, every 3 months, radiographic union was assessed by a simple radiograph and clinical symptoms. Twelve months postoperatively, posttraumatic arthritis was assessed and the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was analyzed. Results: In 7 cases, osteonecrosis was found on MRI performed 3 months after surgery. On the other hand, at the 12 months follow-up, all of them obtained AOFAS scores of 83.86±4.53 without surgical treatment. Radiographic union was achieved in all cases. The mean union period was 5.3 months. In 10 cases, traumatic arthritis was found after the radiographical and clinical evaluation. In addition, all of them could carry on everyday life by conservative treatment. The AOFAS ankle-hindfoot score was measured to be 85.17 on average. Other complications included superficial wound infection in 2 cases. Conclusion: An anteromedial approach using a medial malleolar osteotomy and a large distractor in the surgical treatment of patients with type 3 talar neck fractures can achieve anatomical reduction of the displaced fragment without a lateral dissection. This is considered to be another good surgical option.
