We was constructed of the spread movement with tremor layer point by the tractile-dot structure that was analyzed the squirm quake forms of the perception movement on the atom liquid. Algorithm of squirm quake forms was used to move the spread tremor on the atom state. To detect the tiny signal, we compared the association average value of the squirm quake form on the atom state. Their subject were issued the valuation standard and perception movement for basic atom condition by the spread tremor. We take to detect the tiny scores of average during perception movement side from the spread tremor that magnetic condition get to a variation of the Ma-αAVG and Ma-αMAX-MIN with 6.25±0.35 units, that electric condition get to a variation for the El-αAVG and El-αMAX-MIN with 5.68±0.42 units. The spread tremor was to investigate the capacity of the tremor form, to uptake a spread data of spread tremor level on the CCPL that was denoted the calm-classification form by the spread perception level system. As the squirm quake forms was demanded by the spread tremor signal, max-average values of perception movement were checked the spread position for association average data. We make mention of squirm quake forms for a signal association and a quake data signal of relation system.

The purpose of this study was to investigate the effect of kindergarten's factors on athletic movement ability in early childhood. The factors included teacher's perception of athletic movement, length of time for physical activity, and number of athletic facilities in the kindergarten. The subjects consisted of 551 children aged from four to five years in 8 private kindergartens. The instruments used for this study were the obstacle course of Project Spectrum for measuring athletic movement ability, and the questionnaire to investigate the teacher's perception, length of time for physical activity, and number of athletic facilities in the kindergarten. The data from all the tests were analyzed by correlation and regression analyses. The results of this study exhibited that the length of time for physical activity was the most important factor among three factors, and the teachers' perception of athletic movement and the number of athletic facilities in the kindergarten were also deciding factors for the children's athletic movement ability.

The purpose of this study was to investigate the effects of visual properties on the human movement behavior experimentally and empirically using spatial analysis technique based on ecological perception theory. For the survey of choosing behaviors of heading direction in built environments, the experiment was conducted in which the subjects were made to choose moving directions in some spaces using the virtual environment simulation tool, and then comparative analysis was conducted on the interrelation between the experiment results and various visual properties in existing spatial analysis techniques based on ecological perception theory. As a result, the occlusivity of the isovist theory was found to be the most significant index in the human choice of heading direction, and the longest radial also showed somewhat significant effect on it.

The purpose of this research is to investigate Korean architects' perception of the Modern Movement in architecture in the West during the Japanese colonial period, by analyzing two Korean publications in the 1930s: Park Dongjin's 'Present Architectural Tendency' (Dong-A Ilbo, March 1931) and Hong Yunsick's 'Trend in the Thought of Moderne Baukunst' (Chogwang, September 1937). As a result of the investigation, it is confirmed that the two men welcomely accepted the universal modernity, regarding the rational and functional - rather than subjective expressions of the individual - as the key to modern architecture. Although their perception of the Modern Movement in Western architecture was inevitably superficial due to the limited condition of the Japanese colonial period in Korea, there was an obvious advancement in the latter's perception from the former's, reflecting the progress in knowledge of it over the six and a half years between the two. Therefore, it is argued that their 1930s' writings are meaningful as the first Korean publications that illustrate how Korean architectural circles perceived the contemporary architectural movement in the West.

최근의 연구에서 Li, Brenner, Cornelissen과 Kim (2002)은 추적 눈 운동 동안의 2차원 모양지각이 망막에 형성된 이미지 내용을 그대로 반영한다는 것을 보여 주었는데, 이러한 연구는 2차원 모양판단에 있어서 망막 외 정보가 전혀 고려되지 않았음을 시사한다. 이와 같은 실험실 연구와 달리, 실제 생활에서 2차원 모양지각의 왜곡은 대부분의 경우에 발생하지 않는데, 가능한 한 가지 이유는 실험실 연구에서 사용된 자극의 경우에 참조대상이 존재하지 않는데 비하여, 실제 생환에서는 다양한 참조대상이 목표대상의 주변에 존재하기 때문이다. 목표대상과 참조대상의 상대적인 위치관계는 추적 눈 운동 동안에 망막에서도 그대로 유지되는데 시각체계가 이러한 안정적인 관계를 목표대상의 모양을 지각할 때에 이용할 가능성이 있다. 본 연구에서는 다양한 참조대상을 이용하여 이러한 가능성을 검증하였다. 흥미롭게도, 추적 눈 운동 동안에 참조대상이 목표대상 주위에 존재할 때에도 모양지각 왜곡이 관찰되었는데, 왜곡의 양은 참조대상이 존재하지 않을 때에 비하여 감소하였다. 참조대상의 효과는 참조대상과 목표대상의 거리에 비례하였다. 이러한 실험결과는 추적 눈 운동 동안의 2차원 모양지각에 참조대상 정보가 이용되지만, 참조대상에 대한 정보만으로는 실제생활에서의 안정적인 모양지각을 설명할 수 없음을 시사한다.

Wind-induced vibrations of buildings can be perceived when movement of objects caused by the vibration is seen. However, movement of objects that would normally be expected to trigger visual perception of building vibrations is not necessarily seen in actual building environments. Therefore, to evaluate habitability to building vibrations, it is necessary to examine the influence of movement of objects on vibration perception taking into account probability of seeing the objects. As the first step in this study, those data necessary to estimate probability of vibration perception from seeing of swaying objects have been measured during normal activities in actual buildings. In addition, statistical analysis of the data has also been carried out. As the second step in this study, the probability distribution of vibration perception by visual sensation is estimated using the series of data measured in the first step. Probability of seeing object is considered in the estimated probability distribution.

본 논문의 목적은 제한적 인지에 기초한 가상인간 에이전트의 움직임-데이터 궤적이 인간과 유사하다는 것을 보이는 것이다. 이 움직임-데이터 궤적의 인간 유사성을 결정하기 위해서, 우리는 두 파라미터들 -사실적으로 제한된 인지(RLP: Realistically Limited Perception) 데이터와 점증적 움직임 경로 데이터의 생성 (IMPG: Incremental Movement-Path Generation)- 사이의 상호작용을 활용한다. 즉, 어떻게 전자인 인간사고 혹은 그 구성요소의 모의 파라미터(즉 RLP 데이터)가 후자인 인간 움직임-데이터 궤적의 모의 파라미터(즉 IMPG 데이터)를 지배하는지를 에이전트 움직임-데이터 궤적에서 고찰하는 것이다. 지도 제작 DB는 인지와 움직임 경로-데이터 생성 사이의 인터페이스이므로, 에이전트에게 항해를 위해 필요한 선결 요소이다. Hill과 동료들에 의해 RLP에 의한 지도 DB 제작은 연구되었지만, 이러한 기존의 연구들은 단지 렌더링 카메라의 시점 데이터의 변화에 의해서만 수행되었다. 이에 비해 본 논문에서는 Hill의 지도 DB 제작 모듈을 에이전트 시스템에 통합하여 예기치 않은 적 출현을 수반한 정찰 임무 상에서 두 파라미터 데이터간의 상호작용을 고찰하였다. 인간 피실험자와 에이전트에 의해 생성된 움직임 데이터의 궤적들이 서로 비교되었다. 비록 에이전트 움직임-데이터 궤적의 인간유사성이 두개의 파라미터 데이터들(즉 RLP와 IMPG)과 단지 30명의 피실험자들로 얻어진 파일럿실험(pilot-test)의 결과이지만, 본 연구의 에이전트 시스템은 인간과 유사한 움직임-데이터를 생성하기 위한 최소한의 기능적인 테스트베드(functional testbed)가 될 수 있음을 입증하였다.

As recent virtual reality technologies provide a more natural three-dimensional interactive environment, users naturally learn to explore space and interact with synthetic objects. The virtual reality researcher develops a technique that realizes realistic sensory feedback to get appropriate feedback to sense input behavior. Although much recent virtual reality research works extensively consider the human factor, it is not easy to adapt to all new virtual environment contents. Among many human factors, distance perception has been treated as very important in virtual environment interaction accuracy. We study the experiential virtual environment with the feature of the virtual object connected with the real object. We divide the three-dimensional interaction, in which distance perception and behavior have a significant influence, into two types (whole-body movement and direct manipulation) and analyze the real and virtual visual distance perception heterogeneity phenomenon. Also, we propose a statistical correction method that can reduce a near-body movement and manipulation error when changing the interaction location and report the experiment results proving its effectiveness.

The purpose of this study is to analyse the diagrammatic design approaches and programmatic design approaches in contemporary architecture, so that this reveals the sequential systems of circulation in the space and liberal movement of the visitors in the buildings of those diagrammatic and programmatic architecture. Contemporary architecture generates the new forms and meanings through the dynamic visions and perspectives. Such a variation of sequential vistas and dynamic visions produce a perception of time and a potential movements of axis in the perspective. This study give the systematic body to the relations among visions, movements, sequences, forms, circulations and time. Diagrammatic and programmatic design approaches show the heterogeneous spaces and the informal architectures in contemporary architecture. Therefore, movements of various view points, differrentiations of objects in the perspectives, and multiple view frames appears in the designs of initiative architects. In conclusion, this study systemizes the concepts of time, sequential movements, and perceptions of events in contemporary architecture through the analyse of 18 architectural works of important architects in 2000s. And this shows details of the transitional movement of space and the perception of time in contemporary Architecture. The Being of the active time constructs formal transformations, spacial differentiations, accumulations of human behaviors, and movements of circulations involved with experiences of the field of senses. Therefore, Zeitlichkeit is perceived through concepts of the sequences of those spaces, forms, behaviors, and memories.

Recently it is coming to be hish reality on visual system in ship-handling simulator depending on the technical development of 3D computer graphics. Even with high reality, it is possible that visual information presented seafarers through screen or display is not equivalent to the real world. In docking maneuvering, visual targets or obstructs are sighted close to ship's operator or within few hundred meters, so it might be possible to affect visual information such as the difference between both eyes' and single eye's visual sight. Because it is not possible to perceive of very slow ship's movement by visual in case of very large vessels, so the Doppler Docking SONAR and/or Docking Speed and Distance Measurement Equipment were developed and applied for safety docking maneuvering. By the way, the simulator training includes the ship's maneuvering training in docking, but in Ship-handling Simulator and also onboard, there are some limitations of perception of ship's movement with visual information. In this paper, perception of ship's movement with visual system in Ship-handling Simulator and competition of performances of visual systems that are conventional screen type with Fixed Eye-point system and Mission Simulator. We got some conclusions not only on the effectiveness for visual system but also on the human behavior in docking maneuver.
