  • 수두증 환자를 치료하기 위해 머리에 시술 되는 션트밸브가 받는 뇌압 펄스가 밸브의 유량조절 특성에 미치는 영향을 수치적으로 해석하였다. 션트밸브를 통한 유량을 계산하기 위하여 밸브 다이아프램이 형성하는 유량 오리피스를 모델링 하여 맥동압력과 변동하는 압력에 의한 다이아프램의 움직임을 고려하였다. 연구 결과, 압력 펄스와 이에 따른 다이아프램의 움직임에 의하여 유량이 40% 이상 증가함을 보였다. 이 결과는, 뇌실에 시술 되는 션트밸브의 압력-유량 조절특성이 제조 직후 맥동이 없는 유량을 공급하는 시린지 펌프를 사용하여 구한 실험 결과와 상당히 다르다는 사실을 보여주었다.

  • 영화 아바타의 성공 이후, 3D 영화의 성공 사례가 계속 이어지지 못하고 있다. 3D 영상이 성공하기 위해 많은 것을 고려해야하지만, 특히 휴먼팩터 부분을 간과시한 결과가 아닌가 하는 주장이 제기되고 있다. 3D 영상이 시청자에게 어떠한 영향을 미치는지 이제 막 초기 연구가 실행되고 있는 상황에서 본 연구는 3D 영상 시청 후 시청자의 심리적 반응을 인지된 특성, 프레즌스, 시각 피로도 그리고 양안운동 지각을 통해 측정하고자 했다. 90명을 대상으로 한 실험연구 결과 첫째, 인지된 특성은 프레즌스에 영향을 미치고 인지된 특성의 세부 요인 중 실물감이 프레즌스에 영향을 미치는 것으로 나타났다. 둘째, 프레즌스의 경험정도가 높을수록 인지된 안구운동이 증가했지만, 시각피로도는 감소하였다. 이처럼, 프레즌스가 눈 움직임 지각과 시각피로도에 미치는 영향이 가지는 첫 번째 함의는 다음과 같다. 우리가 눈을 움직인다는 것은 우리가 미디어적인 도구로서 우리의 눈을 사용한다고 여기기보다는 눈과 함께 환경과 상호 작용하고 있다는 것이다. 따라서 콘텐츠에서 경험할 수 있는 상호작용의 요소들이 많아야 할 것이라고 추론할 수 있으며 이를 후속 연구를 통해 검증하는 것이 필요할 것이다. 다음으로는 프레즌스의 요인 중 시간 관여가 높아짐에 따라 시각피로도에 대한 지각이 감소한다. 반면 몰입 실재감이 증가함에 따라 시각피로도는 증가하게 되므로 콘텐츠 제작 시 몰입 실재감을 높이는 효과는 일정 수준이상이 되지 않도록 조절해야 할 것이다. 이를 위해 프레즌스에 영향을 미치는 인지된 특성변인 중 실물감 요인이 프레즌스의 세부요인별로 어떠한 영향을 미치는지, 프레즌스에 영향을 미치는 다른 변인은 무엇인지를 후속 연구를 통해 알아볼 필요가 있을 것이다.

  • Multimodal interfaces are recognition-based technologies that interpret and encode hand gestures, eye-gaze, movement pattern, speech, physical location and other natural human behaviors. Modality is the type of communication channel used for interaction. It also covers the way an idea is expressed or perceived, or the manner in which an action is performed. Multimodal Interfaces are the technologies that constitute multimodal interaction processes which occur consciously or unconsciously while communicating between human and computer. So input/output forms of multimodal interfaces assume different aspects from existing ones. Moreover, different people show different cognitive styles and individual preferences play a role in the selection of one input mode over another. Therefore to develop an effective design of multimodal user interfaces, input/output structure need to be formulated through the research of human cognition. This paper analyzes the characteristics of each human modality and suggests combination types of modalities, dual-coding for formulating multimodal interaction. Then it designs multimodal language and input synchronization method according to the granularity of input synchronization. To effectively guide the development of next-generation multimodal interfaces, substantially cognitive modeling will be needed to understand the temporal and semantic relations between different modalities, their joint functionality, and their overall potential for supporting computation in different forms. This paper is expected that it can show multimodal interface designers how to organize and integrate human input modalities while interacting with multimodal interfaces.

  • Floor vibrations in residence and office buildings are typically induced by heel drop and walking movement of occupants. The criteria of most vibration provisions have been developed based on the vibration caused by heel drop impact rather than walking. There may be considerable differences between the vibration characteristics induced by walking and heel drop. The effect of walking vibration was not well reflected on current provisions. In this paper, shaking table test was performed to investigate the human perception level against the vibrations due to walking and heel drop. This study attempts to compare the human Perception level of two different vibration sources. Also, this study investigates the effect of damping on a Perception level under heel drop and walking vibration.

  • In modern times, text has become an image, and typography is a style that is a combination of image and text that can be easily encountered in everyday life. It is developing not only for the purpose of conveying meaningful communication, but also to bring joy and beauty to our lives as a medium with aesthetic format. This study shows through case analysis that typography is a tool for expressing human emotions, and investigates its characteristics that change along with the media. In particular, interactive communication tools and methods used by interactive typography to express viewers' emotions are described in detail. We created interactive typography using the inputted text, the selected music by the viewer and the viewer's movement. As a result of applying it to the exhibition, we could confirm that interactive typography can function as an effective communication medium that shows the utility of both the iconography of letter signs and the cognitive function when combined with the audience's intentional motion.

  • This study examines Dalibor Vesely's theoretical proposition of communicative space and tries to develop it through a review of the contemporary architectural case. Vesely poses a critical question about communication: how do the situational conditions of our everyday life and the spatial characteristics of the natural world in which we live communicate through representation. He emphasizes the spatial and situational conditions and the role of representation in communication, arguing that architecture should create the formation of communicative space to restore its primary role as the corporeal foundation of culture. This study thus focuses on one of the critical concepts of his theory: "the communicative movement," which is, according to him, ontological and situational because it animates and transforms human circumstances as a whole. Further, it pursues some practical knowledge of creating the communicative space, by examining the design theory and practice of Zaha Hadid, who thematizes communication and movement in her architectural approach. This study analyses the different levels of representation and modes of movement in her architectural space to reveal the possibilities and limits of its communicative roles. We will find that the representation of Hadid's architectural space is not the formal representation of reality, but a mathematical and projective representation of abstract concepts. Despite its apparent aesthetic consistency, the inward and self-referential relation between the individual elements of the architectural space reveals its limit for the communicative space.

  • Landslides can be caused by localized intense rainfall. The loss of human lives and damage to property from landslides is increasing. However, little information exists on the movement and flow of sediment material at the time of rapid landslides. In this study, a field survey was conducted of landslides that occurred in 2013 in the Hadari area of Yeoju city in Korea. This was followed by numerical analysis. The purpose is to analyze the characteristics of a consequent debris flow and its movement at the time of failure. The results of the field survey and numerical analysis are consistent with each other. The maximum velocity of the debris flow was ~9.335 m/s and the maximum sediment thickness ~4.674 m. The latter is similar to the traces of debris flow observed in the field.

  • Wild boars(Sus scrofa) are expanding their range of behavior as their habitats change. Appearing in urban centers and private houses, it caused various social problems, including damage to crops. In order to prevent damage and effectively manage wild boars, there is a need for ecological research considering the characteristics and movement characteristics of wild boars. The purpose of this study is to analyze home range and identify land cover types in key areas through tracking wild boars, and to predict the movement connectivity of wild boars in consideration of previous studies and their preferred land use characteristics. In this study, from January to June 2021, four wild boars were captured and tracked in Jinju city, Gyeongsangnam-do, and the preferred land cover type of wild boars was identified based on the MCP 100%, KDE 95%, and KDE 50% results. As a result of the analysis of the home range for each individual, it was found that 100% of MCP was about 0.68km2, 2.77km2, 2.42km2, and 0.16km2, and the three individuals overlapped the home range, refraining from habitat movement and staying in the preferred area. The core areas were analyzed as about 0.55km2, 2.05km2, 0.82km2, and 0.14km2 with KDE 95%., and about 0.011km2, 0.033km2, 0.004km2, and 0.003km2 with KDE 50%. When the preferred land cover type of wild boar was confirmed based on the results of analysis of the total home range area and core area that combined all individuals, forests were 55.49% (MCP 100%), 54.00% (KDE 95%), 77.69% (KDE 50%), respectively, with the highest ratio, and the urbanization area, grassland, and agricultural area were relatively high. A connectivity scenario was constructed in which the ratio of the land cover type preferred by the analyzed wild boar was reflected as a weight for the resistance value of the connectivity analysis, and this was compared with the connectivity evaluation results analyzed based on previous studies and wild boar characteristics. When the current density values for the wild boar movement data were compared, the average value of the existing scenario was 2.76, the minimum 1.12, and the maximum 4.36, and the weighted scenario had an average value of 2.84, the minimum 0.96, and the maximum 4.65. It was confirmed that, on average, the probability of movement predictability was about 2.90% better even though the weighted scenario had movement restrictions due to large resistance values. It is expected that the identification of the movement route through the movement connectivity analysis of wild boars can be suggested as an alternative to prevent damage by predicting the point of appearance. In the future, when analyzing the connectivity of species including wild boar, it is judged that it will be effective to use movement data on actual species.
