  • Since last several decades, iconic memory has been accepted theoretically valid for its role of the first storage mechanism in visual memory process. However, there have been relatively less interests in iconic memory among researchers than their interests in visual short- and long-term memory. Such little interests seem to arise from a lack of detailed understandings of theories and methodologies about iconic memory and visual persistence. This study aimed to achieve the understandings by reviewing theories and empirical studies of iconic memory and visual persistence. The study further discussed future direction of iconic memory research according to the essential aspects of phenomenological and ecological criticisms against the validity of iconic memory.

  • Objectives: This research was performed in order to observe the neuropsychological implication and functional anatomical source of event related potentials(ERP) by studying of correlations between event related potentials and neuropsychological tests. Methods: The latency and voltage of P100 of visual evoked potential (VEP), and N120 and P300 of event related potentials were studied in 56 patients and their correlations with neuropsychological tests were computed. Results: The tests showing significant correlation with latency P100 were visual continous performance test(VCPT) and contingent continous performance test(CCPT) without any significant correlation with voltage of P100. In latency of N120 category test and verbal IQ of KWIS showed significant correlation, and in voltage of N120, finger tapping test, VCPT, CCPT and digit symbol test displayed significant correlations. The latency of P300 had significant correlation with trail making A test and Stroop test. In the voltage of P300 significant correlations were shown with trail making B test, digit symbol test and Wechsler memory scale, finger tapping test, stroop test, VCPT and CCPT. Conclusion : N120 may be considered to reflect the function of medial frontal lobe and P300 may be considered to be developed from the subcortical connection of medial temporal lobe, hippocampus, thalamus, basal ganglia and medial frontal lobe.

  • The purpose of this study is to implement a visual organizer which enables learners to support web navigation as well as visual understandings in the electronic document space. I developed a visual organizer according to design principles of visual organizer, and then analysed the effect of a visual organizer on the students' disorientation, perceived usefulness, perceived usability, satisfaction and use intention. According to the result, using the visual organizer was more effect than conventional web-based instruction in view of navigation and visual understandings.

  • Information of video can be percieved as the form of visual rhythm through temporal ordering systems. The shot, the base unit of video analysis, affects audience psychologicaliy with various temporal combination. Here, psychological stress and density of the story can be adjusted by the point of view shot of character. Acordingly the correlation analysis of shot duration and point of view shot can be useful for visual rhythm research. Identity one of the thriller genre works was selected for analyzing.

  • 최근 스마트 기기에 대한 관심이 지속적으로 증가함에 따라 다양한 스마트 기기가 출시되고 그에 대한 연구가 활발히 진행되고 있다. 기존 스마트 기기에 탑재된 모션 센서에 관한 연구 대부분은 사용자의 움직임을 이용한 게임 연구에 치우쳐 있다. 본 논문은 사용자 모션의 시각화라는 접근을 통해 사용자의 모션을 직관적으로 볼 수 있도록 하였다. 안드로이드 기반 모바일 기기에 탑재되어 있는 모션 센서 중 방향 센서를 이용하여 사용자 모션에 대한 데이터를 수집하고 이를 시각화 알고리즘을 통해 시각화 한다. 시각화한 결과를 손 글씨 숫자 이미지의 대형 데이터베이스 기반 머신러닝을 활용하여 분석하고 사용자의 모션을 인식할 수 있다는 결과를 확인했다.

  • Mis-en-Scene is a direction method of image aesthetics for constructing screen and space. Mis-en-Scene is important factor not only in plays and movies, but also in animations, and it is a strong method to induce audience to immerse in the works and to continue the immersion. This study examined animation's Mis-en-Scene based on theories of Mis-en-Scene in movies, how Mis-en-Scene is directed and expressed in virtual spaces, and what factors and characteristics induce audience to immerse in the works and continue the immersion through analysis on visual Mis-en-Scene factors of a specific case, VR animation . It was found that as visual Mis-en-Scene factors, character and props, background, unique quality and friendliness of character, natural movement and acting, symbolism and utilization, and variety and consistency of background induce and sustain immersion. It is thought that this study would helpful for related areas based on the findings which suggest that there is a need for differentiated measure and method to catch audience's eyes and sustain immersion utilizing characteristics of vidual Mis-en-Scene factors in VR animation in the future.

  • In general, industrial production involves large amounts of harmful by-product, causing serious pollution and ecological risk. Eco-efficiency, which indicates how efficient the economic activity is by considering both the environmental risks and economic performance, is a new concept for economic sustainability analysis and quantitative ecological risk analysis. Data envelopment analysis (DEA) has been widely used to examine eco-efficiency in recent years. Whereas traditional DEA models such as CCR and BCC model neglect undesirable outputs, this paper adopts a stochastic undesirable-output DEA model to measure the eco-efficiency of each province of China and Korea. The results indicate that whereas the eco-efficiency of the eastern region was the highest, that of the western region was the lowest. The reason may come from the negative external dis-economies of environment. And thus the governmental efforts for outreach on the underdeveloped regions should be promoted.
