  • Recently, English education of educational institutions is gradually invigorated as the importance of English education for preschooler is increasing. Role-play, in particular, is known as an effective way to learn English for children because it promotes children's interest in language and naturally encounters English-speaking culture. Therefore, in this paper, we tried to find out how to effectively use UCC in role-playing for English education for preschoolers. First of all, questionnaires for pre and post-test were conducted for preschoolers. The results are analyzed by SPSS to find out children's understanding of UCC, interest in English, interest in role-playing, and interest in acting. As a result of the analysis, most children knew UCC well and showed strong interest in watching and producing UCC. Also, the more interested in English and role-playing, the more they wanted to show more advanced English and acting through the feedback of the contents they produced. Therefore, even in preschool children's English education, the development of language and acting can be shown by producing UCC through role-playing under the teacher's control and receiving feedback on it. The results of this study are expected to be effectively used when planning English education through role-playing in daycare centers or kindergartens.

  • The experiment applied Positive Pressure Ventilation to rapidly exhaust heat and smoke inside the construction in the fire was done. Changes of heat discharge and smoke density were measured, with the various blowing condition like a fan tilting angle to find the effect of the parameter. Experimental apparatus were with PPV and water mist system for better efficiency, and investigate the effect of heat discharge and smoke removal. In the experiment, flame temperature has decreased when PPV was applied. Smoke density, generated from fire also decreased dramatically and the efficiency showed the highest rate at $0^{\circ}$ tilting angle. In addition, combination of PPV and water mist system highly improved the efficiency of evacuation on heat and smoke density, clearly was influenced by the tilting angle.

  • We propose an algorithm for video effects of sports broadcasting that informs TV viewers of a sports player's sequential performing forms and locus in detail when gymnastic game such as 'vault' is broadcasted. It records the image sequences while a player is performing, extracts only the player's performing forms from background scenes by a proposed algorithm, superposes them sequentially on a background scene, and broadcasts them with slow speed. This system named as 'Multi-Motion' has ever been used in NHK live broadcasting for 1995 World Gymnastics Championships held in Japan.

  • A fire in a clean room may cause a serious loss by spreading smoke particles. The effects of the width of smoke curtains on delay in smoke spread, which is located the work area boundaries, were investigated by using a computational fluid dynamics, for loss prevention by smoke spreading from one fire area to another. The fire scenario was set to a 1 MW methanol fire in a space of $30m\times10m$ floor and 4 m high. Distributions of temperature and smoke particles were compared for the width of the smoke curtains 0 (without smoke curtains), 1, 2, 3m. It was confirmed that a larger width of the smoke curtain delays spread of smoke more, and that making the work areas compartments is necessary to confine the smoke in the fire area.

  • In this paper, we propose an algorithm that can accurately segment a fire even when it is surrounded by smoke of a similar color. Existing fire area segmentation algorithms have a problem in that they cannot separate fire and smoke from fire images. In this paper, the fire was successfully separated from the smoke by applying the color compensation method and the fog removal method as a preprocessing process before applying the fire area segmentation algorithm. In fact, it was confirmed that it segments fire more effectively than the existing methods in the image of the fire scene covered with smoke. In addition, we propose a method that can use the proposed fire segmentation algorithm for efficient fire detection in factories and homes.

  • Recently, in order to solve the traffic congestion in urban areas and to improve the peripheral environment, research on the design and construction technology development of great depth underground double-deck tunnel is under way by using the underground space in the urban area. The network type double-deck tunnel is in the form of an intersection with a small cross section and a steep slope as per construction at the base of a flatland, so that the fire smoke spreads rapidly in case of fire, which is expected to cause damage of human life. Therefore, this study is analyzed the delay effect of fire smoke diffusion according to the installation and non - installation of delay system for fire smoke diffusion at the intersection. Fire fumes were delayed up to 270 seconds when the delay system for fire smoke diffusion was installed at the intersection and it is analyzed that the greater the operating area of the delay system for fire smoke diffusion, the more preventable the damage of human life of the intersection.

  • 고층 건물에서 혹한기에 심하게 발생하는 연돌효과는 건물 외벽 및 창문에 구조적 영향을 미치고, 제연기능을 기능을 저해하고, 승강기 문 개폐 장애와 소음 및 공조기능 장애 등 설비 기능에 부정적 영향을 미치며, 화재시 승강기 승강로 등 수직 샤프트를 통해 연기를 전파시킨다. 계단실의 상하부를 화재 시 자동으로 개방함으로써 계단실의 기류 유동 마찰을 이용하여 연돌효과를 대폭 줄일 수 있고, 승강기 승강로 또한 상하부를 개방함으로써 승강로와 거실 사이의 차압을 줄여서 연기의 전파를 막을 수 있다. 샤프트 복합효과를 이용하여 차압을 상당부분 제어할 수 있으며, 일반용 샤프트만으로 샤프트 복합효과를 일으키기에 부족한 경우에는 연돌효과 제어 전용 보조 샤프트를 검토할 필요가 있다.

  • The purpose of this research is to investigate the usage of voice scripting for speech characterization. The ultimate goal of acting is for an actor to create one's character both in physical and vocal sense, and to present them on stage. Toward this goal, actors train themselves with various methods and techniques as well as character analysis. Most of their efforts are put into for better physical and vocal expression. The vocal characterization on stage is heavily governed by the proper speech based on the effective respiration and voice. This paper provides the way of how to use sound scoring for effective vocal characterization on stage.

  • I discussed how the Zen training could be used to previous acting training methods focused on the way draw efficiently subconsciousness in the process of the training of actors. It is believed that the practice of the Zen would contribute to the development of training subconsciousness of actors. I examined the validities of the Zen practices which could be helpful to young students and existing actors' training processes and started from the existing proven analyses of mental and psychological effects of it. It is certain that the practices of Zen is a new continent which has infinite possibilities of analyzing and studying in terms of thinking highly of the Zen and brain science together. If we would utilize the Zen efficiently in the course of training actors, we could achieve four elements: the first, a trigger to operate actors' subconsciousness, the second, establishing the presence of actors through the reinforcement of concentration, the third, overcoming any mental and psychological obstacles, and the fourth, the establishment of transformation skills through the combined use of left and right brains. Additionally, actors could have mental and psychological stability through the Zen practice in their daily lives. I believe that we could also find a unique Eastern actor training way through vigorous and practical following analyses and practices which are based on the Zen tradition for training actors' subconsciousness and unconsciousness.

  • In this paper, the smoke behavior in an underground station on operation of the fans in the ventiliation of the station was measured by the experimental method when the fire occurred in the underground station platform where the platfrom screen door was installed. The ventilation characteristics were compared when the ventilation system was operated and when the ventilation system was not operated when a fire occurred at the platform where the clean door was closed. To simulate the fire smoke, the smoke generated from the smoke generator was heated using a hot air fan. The transmittance was measured using a smoke density meter to quantitatively measure fire smoke. If the screen door is closed and the ventilation system of the underground station does not work, it is confirmed that if a fire occurs in the platform, smoke accumulates inside the platform, evacuating passengers is very difficult and can lead to a very dangerous situation. On the other hand, under the condition that the ventilation facility of the subway station is operated, the smoke evacuates to the outside through the ventilation facility of the underground station, and airflow is formed in the direction from the waiting room to the waiting area, so that the passenger located on the platform can safely evacuate toward the concourse. In the following paper, we will discuss the concurrent effect of tunnel ventilation through tunnel vent near the platform.
