Attentional blink is observed in an identification task of multiple targets during rapid serial visual presentation (RSVP) where performance for the second target (T2) that follows within 500ms of the first (T1) shows systematic decrease although that for T1 remains highly accurate. Theories accounting for attentional blink can be classified into two broad categories of resource depletion model and disruption of input filter model. Meanwhile, visual attention capacity shows hemifield independence between left and right visual fields, and many studies reported bilateral advantage in a range of visual working memory tasks. The current research tested two major theories of attentional blink using bilateral independence of attentional capacity. To this end, we conducted two experiments where two RSVPs were presented in either bilateral or unilateral visual fields. Experiment 1 presented two RSVPs which contained both T1 and T2 in either bilateral or unilateral visual fields and tested interaction between attentional blink and bilateral advantage. Experiment 2 removed T1 in one of the two RSVPs to test whether attentional blink obtains when identification of T1 and T2 utilize independent sources of attention across two visual fields. The results showed that subjects were more accurate when two RSVPs were presented in bilateral visual fields (i.e., bilateral advantage) although there was no interaction between attentional blink and bilateral advantage (Experiment 1). In addition, attentional blink for T2 was observed in a T1-absent RSVP even when two RSVPs were presented in bilateral visual fields (Experiment 2). These results support disruption of input filter model rather than resource depletion model.

Recently, a method of finding the attention area or localization area for an object of an image using CAM (Class Activation Map)[1] has been variously carried out as a study of WSOL (Weakly Supervised Object Localization). The attention area extraction from the object heat map using CAM has a disadvantage in that it cannot find the entire area of the object by focusing mainly on the part where the features are most concentrated in the object. To improve this, using CAM and Selective Search[6] together, we first expand the attention area in the heat map, and a Gaussian smoothing is applied to the extended area to generate retraining data. Finally we train the data to expand the attention area of the objects. The proposed method requires retraining only once, and the search time to find an localization area is greatly reduced since the selective search is not needed in this stage. Through the experiment, the attention area was expanded from the existing CAM heat maps, and in the calculation of IOU (Intersection of Union) with the ground truth for the bounding box of the expanded attention area, about 58% was improved compared to the existing CAM.

본 논문은 상향식 현저함 모델을 이용하여 입력 영상으로부터 시각적 주의를 갖는 영역들을 자동으로 검출하는 방법을 제안한다. 제안한 방법에서는 인간의 시각 시스템과 같이 사전 지식 없이 시각정보의 공간적인 분포에 근거하여 장면을 해석하는 상향식 현저함 모델 방법을 입력 영상에 적용하여 관심 물체 영역을 검출하는 연구이다. 상향식 현저함 방법은 Treisman의 세부특징이론 연구에서 제시한 바와 같이 시각적 주의를 갖는 영역은 시각정보의 현격한 대비차이를 가지는 영역으로 집중되어 배경에서 관심영역을 구분할 수 있다. 입력 영상에서 현저함 모델을 통해 3차원 현저함 맵을 생성한다. 그리고 생성된 현저함 맵으로부터 실제 관심영역들을 검출하기 위해 제안한 방법에서는 적응적 임계치 방법을 적용하여 관심영역을 검출한다. 제안한 방법을 관심영역 분할에 적용한 결과, 영역 분할 정확도 및 정밀도가 약 88%와 89%로 제시되어 관심 영상분할 시스템에 적용이 가능함을 알 수 있다.

This study aims to logically investigate the changing interpretation and implementation of the principle of provenance by using an argument model for discourse analysis. First, it divides the history of discourses on the principle from the Dutch Manual publication of 1989 up to the present into four areas, which includes establishing, diffusing, transforming, and expanding or deconstructing, and articulates the core discourses of each. Second, it designs the argument model for analyzing the discourses on the principle by applying Toulmin's argument model and Dunn's policy argument model. Third, it selects the articles and books that cover the core discourses of the principle, and analyzes their contents in consideration of the argument model. Fourth and finally, it presents four argument models corresponding to each area of the discourses.

This paper takes a bottom-up attention module into consideration for digital image watermarking. A bottom-up attention module is employed to obtain the region of interest, and watermark information is embedded into the obtained region. Previous studies in digital image watermarking have been focused on the signal processing techniques, especially in waveform coding spreading watermarks over the entire target image. However, we notice that the third party's visual attention is usually concentrated on a few regions in an image but not on all of them. These regions are easy to be the target of attacks. If watermark information is inserted into these regions from the beginning, it can be detected with high correlation. Various kinds of images are tested, and the results showed good quality.

Human visual attention system has a remarkable ability to interpret complex scenes with the ease and simplicity by selecting or focusing on a small region of visual field without scanning the whole images. In this paper, a novel feature map generation and integration method for attention based visual information processing system is proposed. The depth information obtained from a stereo pair of images is exploited as one of spatial visual features to form a set of topographic feature maps in our approach. Comparative experiments show that correct detection rate of visual attention regions improves by utilizing depth feature compared to the case of not using depth feature.

This paper aims to critically discuss the place-marketing strategy that has been widely seen as an alternative way of regional development for the last decade in South Korea. In particular, it argues that the place-marketing strategy is highly likely to intensify the inter-local or inter-urban completion and to result in the territorialization of places because it is based on the essentialist notion of place that has been suggested by the humanistic geographers. In order to logically support my argument, I will critically review the essentialist notion of place, and introduce an alternative notion of place, in which the place is seen as socially constructed through complicated power relations and social, political and cultural processes. Also, I will logically demonstrate that the place-marketing can be seen as a strategy for territorializing places by discussing how territory is socially and politically constructed as a particular form of place.

This paper examines how Nietzsche, criticizing anti-naturalist philosophies, reformulated concepts of nature and human nature, and revaluated them from the perspective of naturalism. Especially, it focuses on his task for naturalistic ethics to naturalize nature and to place man back into nature. This paper also tries to reinterpret his attempt to transfer the concept of justice from the metaphysical realm to the naturalistic one, which seems to give some important insights to develop theory of environmental justice, while pointing out some limitations in his naturalistic concept of justice.

This paper analyzes the effects of national culture on an individual's ethical decision-making in the context of the Internet. An ethical decision-making model which posits that five moral philosophy variables-justice, relativism, egoism, utilitarianism, and deontology-affect ethical judgment; ethical judgment, in turn, affects behavioral intention was proposed and Hofstede's five cultural dimensions of power distance, individualism, masculinity, uncertainty avoidance, and long-term orientation were used to analyze the effects of national culture on the model. The results showed that power distance, individualism, and masculinity had significant effects on the relationship between the deontology variable and ethical judgment, individualism, masculinity, and uncertainty avoidance had significant effects on the relationship between the justice variable and ethical judgment, and individualism and long-term orientation had significant effects on the relationship between ethical judgment and behavioral intention in the Internet context.
