This study aimed to empirically analyze the effect of the appreciation of artwork in the workplace on creativity. To this end, two virtual workspace images with and without artwork were created, and an online survey was conducted with office workers. A regression analysis was performed on the results to investigate whether and how much the appreciation and recognition of artwork was effective for the creativity. As a result, among the factors of recognition according to the appreciation of artwork, "intellectual development" and "thinking" showed positive effects on the five sub-factors of creativity at work, such as original flexibility, alternative problem-solving skills, pursuit of adventure and freedom, individual independence, and exploratory immersion. Unlike most previous studies, however, "understanding" had a negative effect on original flexibility. In conclusion, it was found that some of the factors of the appreciation and recognition of artwork had a positive effect on creativity at work. This study provides implications that the appreciation of artwork in the workplace is effective for improving creativity at work and that it is important for each company to develop a streamlined approach based on its goal of pursuing a creative environment. In addition, it is expected that this study will contribute to the widespread use of artwork sharing services at workplaces as well as encouraging more empirical studies to be done on the effect of the services.

The volume rendering has become an important technique in many applications along with hardware development. Understanding and perception of volume visualization benefit from visual cues which are available from shading. Better visual cues can be obtained from global illumination models but it's huge amount of computation and extra GPU memory need cause a lack of interactivity. In this paper, in order to improve visual cues on volume rendering, we propose an image space occlusion shading model which requires no additional resources.

유비쿼터스 컴퓨팅 환경에서 시스템은 사용자의 상황을 인지하여 그 상황에 적합한 서비스를 자동으로 생성하고 그 환경에 존재하는 장치들을 사용하여 제공할 수 있어야 한다. 서비스를 수행하는 주체는 사용하려는 장치들의 상태 정보를 알고 있어야 하며, 그 서비스가 현재 환경에 적합한 서비스인지를 결정할 수 있어야 하며, 현재 환경에서 제공 가능한 서비스를 사용자가 원하는지 파악할 수 있어야 한다. 이처럼, 서비스를 수행함에 있어 장치, 사용자, 환경으로 구성된 공간 정보의 판독은 필수 불가결한 요소이다. 따라서, 새롭게 도입되는 서비스가 기존 공간 정보를 파악하기 위한 공용 환경 모델이 필요하다. 본 연구에서는 온톨로지를 사용한 환경 모델을 제안한다. 공간 안에 모든 시스템은 이 환경 모델을 통해 자신의 서비스를 수행하는 과정에서 필요한 상황 정보를 인지할 수 있고, 이는 보다 효율적인 개인화 서비스를 제공하기 위한 기반으로 사용될 수 있다.

This paper is an attempt to explore semiotic representations of subway space as the urban machine space of local mobility in terms of space, time and place. For this, the second section of the paper reviews the contours of the urban space of mobility in terms of 'machine space', 'non-place' and 'cognitive map'. The third section interprets the sings of 'spatial' and 'temporal' representations of subway space in Daegu, and suggests the implications of the semiotic representations. It is uncovered that various sign-scapes which coexist in the subway space in coordinated or contradictory ways product the space into multiple and complex techno-social spaces. That is, the spatio-temporal representations of the subway space form the space of 'non-place' on the one hand and the space of 'place' on the other hand, and involve the spatialization of 'memory' on the one hand and the spatialization of 'forgetting' on the other hand. Thus, the subway space should be regarded to be not only the space of 'mobility' which people move in and through, but also the space of 'identity' which has effects on the ways for them to see the machine space and its urban space.

We develop a video processing method that allows the more advanced human perception oriented video coding. The proposed method necessarily reflects all influences by the rate-distortion based optimization and the human visual perception that is affected by the visual saliency, the limited space-time resolution and the regional moving history. For reflecting the human perceptual effects, we devise an online moving pattern classifier using the Hedge algorithm. Then, we embed the existing visual saliency into the proposed moving patterns so as to establish a human visual perception model. In order to realize the proposed human visual perception model, we extend the conventional foveation filtering method. Compared to the conventional foveation filter only smoothing less stimulus video signals, the developed foveation filter can locally smooth and enhance signals according to the human visual perception without causing any artifacts. Due to signal enhancement, the developed foveation filter more efficiently transfers the bandwidth saved at smoothed signals to the enhanced signals. Performance evaluation verifies that the proposed video processing method satisfies the overall video quality, while improving the perceptual quality by 12%~44%.

This paper presents a localization perception of a phantom sound image for ultrahigh-definition TV with respect to various loudspeaker configurations; two-horizontal, two-vertical and triplet loudspeakers. Vector base amplitude panning algorithm with modification for non-equidistant loudspeaker setup is applied to create the phantom sound image. In order to practically study the localization performance in real situation, the listening tests were conducted at the on-axis and off-axis positions of TV in normal listening room. A method of adjustment which can reduce the ambiguity of a perceived angle is exploited to evaluate the angles of octave-band signals. The subjects changed the panning angle until the real sound source and virtually panned source were coincident. A spatial blurring can be measured by examining the differences of the panning angles perceived with respect to each band. The listening tests show that the triplet panning method has better performance than vertical panning in view of perceptual localization and spatial blurring at both on-axis and off-axis positions.

It is hard to understand the coexistence of giftedness and disorder in an individual, but the twice-exceptional is widely recognized now. Gifted autistic spectrum disorder is one of its subtypes in which giftedness exists with autistic spectrum disorder (ASD) simultaneously. Like other constructs including giftedness, the nature of gifted ASD has not been understood in a fundamental and wholistic manner. This paper suggests a cognitive mechanism of gifted ASD based on the integrated model of human abilities(Song, 2009; Song & Porath, 2005), which explains how giftedness coexists with ASD and interacts with each other, producing the characteristics of gifted individuals with ASD. According to the suggested mechanism, the excessive growth of mental spaces in the brain may cause ASD. The over-grown mental spaces result in excessively strong short-term sensory memory and better facility of processing, promoting internal cognitive activities on one hand, but relative lack of cognitive activities in the real world space results in ASD symptoms on the other hand. The cognitive structure of gifted ASD students also contributes to the presentation of giftedness in specific domains. This study suggests that gifted individuals with ASD need to be discouraged from fully engaging in domains they are interested in or the most confident of, rather to be encouraged to invest their giftedness to overcome their ASD symptoms. This study also provides new perspectives on theoretical and educational approaches for gifted ASD.

The main purposes of this study were eliciting the planning contents and indices that is necessary to consider the physical part of public space, the side of service users and coherent side for improving public service. After then it analyzed the importance in both civil servants and practical officials side. For this public space planning topics and indicators by FGI (Focus Group Interview) derived through and through expert questionnaires Analytic hierarchy (AHP: Analytic Hierachy Process) were analyzed by conducting importance. A result, the priority of public space as a park planning index was found in the case of privately owned public space, public pedestrian pathways, public open space, public facilities land, the park is located, and the most important characteristics of the road, if the public transport association the most important thing is derived. In order to enhance the public good public space and location for easy access to the consideration of whether the plan should be. Therefore this work will be the fundamental materials to make some of farther policies related with the development of public interest of private-public spaces.

This study analyzed the impact of securing nature-friendly public spaces on the healthy growth of children. Additionally, it examined the case of Germany to extract implications for Korea. The natural environment enhances children's play, physical activity, cognitive abilities, and overall happiness. Therefore, it is generally considered a necessary space that must be provided for domestically, especially for children who experience high academic stress and low levels of happiness. However, as evidenced by Germany's "Nature Experience Area Project," creating nature-friendly spaces for children requires legal support at the national level. Additionally, such projects should be integrated with key national policies. Furthermore, beyond interdisciplinary collaboration, caregivers must have a positive perception of the natural environment.

High-performing athletes possess the ability to read the game, known as the "sports brain". However, a cognitive battery to measure such sports brain has not been developed yet. The purpose of the study, thus, is to develop a computerized cognitive test battery to measure athletes' cognitive function. Based on a systematic review, information processing speed, execution function, and spatial ability were selected as sports-related cognitive functions. Simple and choice response times test, trail-making test, Flanker test, and mental rotation task were developed. After providing manual and practice trials, main tests were executed and all primary variables were statistically processed and automatically saved. The test battery is expected to aid in the discovery and recruitment of athletes in the future after verifying the validity and reliability of this battery.
