인터랙티브 미디어 콘텐츠에서 메인 캐릭터의 움직임에 따른 주변의 가상영역을 효과적으로 표현하는 방법을 제안한다. 이 방법은 메인 캐릭터의 위치를 고려하여 카메라가 메인 캐릭터를 비추는 것 같은 시각 효과를 유도하는데, 이로 인해 사용자가 인터랙티브 콘텐츠에 자연스럽게 몰입하는 데 도움을 준다. 이때 메인캐릭터를 제어할 수 있는 새로운 인터페이스로 미디어파이프 기반 손 인식 시스템과 음성인식 시스템을 제안한다. 제안한 알고리즘의 성능 평가를 위해 3인칭 RPG 게임을 제작하여, 미디어파이프 기반 손 인식 인터페이스를 사용하여 웹캠 상에 9개 방향으로 메인캐릭터의 움직임을 자유롭게 제어하고, 동시에 음성인식 기법으로 메인캐릭터가 할 수 있는 행동의 다양성을 구현하는 것으로 실험을 통해 제안한 알고리즘에 대한 카메라와 인터페이스의 성능을 확인할 수 있었다. In interactive media content, we propose an effective way to represent the surrounding virtual area as the main character moves. This method takes into account the position of the main character to create the visual effect that the camera is shining on the main character, which helps users feel more immersed in the interactive content. We propose a MediaPipe -based hand recognition system and a voice recognition system as new interfaces to control the main character. To evaluate the performance of the proposed algorithm, we created a third-person RPG game to freely control the movement of the main character in nine directions on the webcam using a MediaPipe-based hand recognition interface, and simultaneously implemented a variety of actions that the main character can perform using voice recognition techniques to verify the performance of the camera and interface for the proposed algorithm.

The exhaust system of automobile is faced with random or spectrum types of fatigue loads during usage life and so needs to be closely estimated for quality and performance to have enough certainty on design endurance life during preliminary design process. Structural operation conditions, operation load history, property of material and manufacturing process etc. should be considered by performing experiment approach. Using the software program for predicting fatigue life quickly and exactly in preliminary design stage saves plenty of time and cost generated by fatigue tests. In this paper, fatigue life prediction was performed on the basis of fatigue analysis using MSC/FATIGUE and load data from field test and the life of development items was estimated and compared through the results.

It is necessary to consider the stability, economic environmental-friendly problems by the development of the road, supply of the automobile, environmental problem as designing the exhaust manifold system. To reduce the noise and the vibration of the automobile, it is needed to consider the pulsation noise, air current noise, vibration of air pipe which generate the intake and exhaust noise of the automobile. Moreover, the discharge sound, intake sound, radiation sound, transmitted sound are occurred. To reduce this influence, the variable valve is needed and to control these factor, path transformation muffler and active type muffler are needed. But engine efficiency could be reduced with this transformation, and resistance by the pressure, thermal property. In this study, in order to establish the optimized conditions design factors which are taking many performance as the variable valve, it shows how the standard performance and the additional element of the exhaust manifold system effects on the engine performance.

Recently, Automobile manufacturers regarding stability, economic environmental-friendly problems by the development of the road, supply of the automobile, environmental problem as designing the exhaust system. Increasingly strict environmental regulations to lower fuel consumption and reduce emission. Also to reduce the noise and the vibration of the automobile. According to develop variable type muffler, dual muffler and active intelligence exhaust system unit. Improvement in engine performance and fuel consumption rate demand information of pressure fraction and heat characteristics. To be able to determine these factor for we experiment on each case of exhaust system unit. In this study, how back pressure is distributed in flow-through adapted semi-active muffler in exhaust system and components.and how to design muffler flexibleness, efficiency, lower back pressure and optimal performance. This study furnish basic data for engineers, technicians.

The muffler to reduce the exhaust noise and vibration from engine influence on the engine performance. Recently, exhaust variable valve setting up in the muffler controls the backpressure in the exhaust system. And the backpressure variation according to the exhaust variable valve opening develop the engine performance.<br/> First, the preceding of structural analysis is needed and simulation experiment is requested for the study on the design factor to influence on the operation of the exhaust variable valve.<br/> In this study, setting up the various variables according to each composition element needed tor the structural analysis of the exhaust variable valve, it is experimented the analysis on the influence of each design factor with the calculation of stress distribution and the displacement to cause about the back pressure for the valve through parameter study.

Recently, Automobile manufactures have developing automotive exhaust system under consideration for improvement in engine performance. It thus develop many exhaust components. For example active muffler, semi-active muffler, electronic muffler etc. In this components consider enhanced back pressure and reduction noise. Especially, In recent years it develop the study of semi-active muffler. Semi-active muffler is simple structure and excel performance. Recently many forms semi-active muffler was developed and adopted to the actual use in consideration of cost and technical side for noise and vibration. This study had main objects about the recently developed the semi-active muffler. It was to show its combustion performance as well as its enhanced back pressure characteristics in design. Therefore if the precise analysis of the combustion pressure according to the back pressure transmission was carried out, it was understood that this study would be utilized in the design of the exhaust system such as the semi-active muffler.
