단어 정체확인 과정을 요구하지 않고 기억 과제와 무관한 단어의 지각적 특질에만 근거하여 공간적 주의를 할당하도록 하는 경우, 이러한 공간적 주의의 차이가 단어의 암묵기억에 미치는 영향을 두 개의 실험을 통하여 알아보았다. 실험 1에서는 독특한 색을 가진 표적자극의색을 판단하는 시각 탐색 과제를, 실험 2에서는 단서가 주어진 위치에 제시된 단어자극의 색을 판별하도록 하는 초점 주의 과제를 실시한후, 단어완성검사를 통하여 암묵기억을 측정하였다. 두 실험 결과, 방해자극뿐 아니라 표적자극에 대해서도 유의미한 점화효과가 관찰되지 않았다. 이는 기억 과제와 무관한 지각적 특질에 주의를 주는 것만으로는 단어에 대한 암묵기억 표상을 형성하기 어려우며, 단어에 대한 암묵기억 표상을 형성하기 위해서는 자극의 부호화 과정에서 단어 정채 확인 과정이 필요함을 시사한다.

In telerobot systems, visual servoing of a task object for a slave arm with an eye-in-hand has drawn an interesting attention. As such a task ingenerally conducted in an unstructured environment, it is very difficult to define the inverse feature Jacobian matrix. To overcome this difficulty, this paper proposes an auto-tuning fuzzy rule-based visual servo algorithm. In this algorithm, a visual servo controller composed of fuzzy rules, receives feature errors as inputs and generates the change of have position as outputs. The fuzzy rules are tuned by using steepest gradient method of the cost function, which is defined as a quadratic function of feature errors. Since the fuzzy rules are tuned automatically, this method can be applied to the visual servoing of a slave arm in real time. The effctiveness of the proposed algorithm is verified through a series of simulations and experiments. The results show that through the learning procedure, the slave arm and track object in real time with reasonable accuracy.

Purpose - This research aimed at exploring the mediation roles of the arousal and pleasure in the effects of the congruity between visual sensory cues of a retail store and consumers' self-image on the intent to reuse the store. Research design, data, and methodology - The data from 278 Chinese consumers who answered the questionnaire online were analyzed by using structural equation model of Amos 21.0 program to verify the hypotheses. Results - Store's visual sensory cues congruent with consumers' self-image directly affected the intention to reuse the store, and had positive impacts on both their arousal and pleasure states. The consumers' pleasure positively influenced on their intention, but their arousal did not influence on the intention. Consumers' pleasure played mediation roles in the effect of the congruity on the intention to reuse the store. Conclusions - Retail store marketers should pay attention to visual sensory cues to match the cues to consumers' self-image, when designing their store settings. When developing the cues, to help consumers feel pleasure which in turn, induces loyalty to their store, the marketers should develop the atmosphere setting in the respects of the congruity between the visual sensory cues and the self image.

As an important research direction of the application of computer science in the medical field, the automatic generation technology of radiology report has attracted wide attention in the academic community. Because the proportion of normal regions in radiology images is much larger than that of abnormal regions, words describing diseases are often masked by other words, resulting in significant feature loss during the calculation process, which affects the quality of generated reports. In addition, the huge difference between visual features and semantic features causes traditional multi-modal fusion method to fail to generate long narrative structures consisting of multiple sentences, which are required for medical reports. To address these challenges, we propose a multi-feature optimization Transformer (MFOT) for generating radiology reports. In detail, a multi-dimensional mapping attention (MDMA) module is designed to encode the visual grid features from different dimensions to reduce the loss of primary features in the encoding process; a feature pre-fusion (FP) module is constructed to enhance the interaction ability between multi-modal features, so as to generate a reasonably structured radiology report; a detail enhanced attention (DEA) module is proposed to enhance the extraction and utilization of key features and reduce the loss of key features. In conclusion, we evaluate the performance of our proposed model against prevailing mainstream models by utilizing widely-recognized radiology report datasets, namely IU X-Ray and MIMIC-CXR. The experimental outcomes demonstrate that our model achieves SOTA performance on both datasets, compared with the base model, the average improvement of six key indicators is 19.9% and 18.0% respectively. These findings substantiate the efficacy of our model in the domain of automated radiology report generation.
