What is the foundation of mathematical thinking? Is it logic based symbolic language system? or does it rely more on mental imagery and visuo-spatial abilities? What kind of neural changes happen if someone's mathematical abilities improve through practice? To answer these questions, basic cognitive processes including long term memory, working memory, visuo-spatial perception, number processes are considered through neuropsychological outcomes. Neuronal changes following development and practices are inspected and we can show there are neural networks critical for the mathematical thinking and development: prefrontal-anterior cingulate-parietal network. Through these inquiry, we can infer the answer to our question.

Map labels are the most recognizable map elements using the human visual system because they are essentially a natural language. In this study, an experiment was conducted using an eye-tracker to objectively record and analyze the response of subjects regarding visual attention to map labels. A primary building object was identified by analyzing visit counts, average visit duration, fixation counts, and the average fixation duration of a subject's gaze for an area of interest acquired using the eye-tracker. The unmarked rate of map labels in Google map, Naver map, and Daum map was calculated. As a result, this rate exceeded fifty-one percent, with the lowest rate recorded for Google map. It is expected that the results of this study will contribute to an increase in the diversity of research in terms of the spatial cognition approach for map labels, which is more helpful to users than the existing body of work on methods of expression for labels.

Pioneer brand and follower brand show differences in their perception of the environmental uncertainty. Market pioneer brand companies think that the environment is relatively simple and doesn't change much, whereas follower bland companies think that the environment is complicated and changes a lot. For market pioneer brand companies, among dynamism on the environment lever, there was less potential for the environment and parts, and government restrictions compared to follower brand companies. Also the complexity of the environment level complicated compared to the follower brand companies in areas such as competition for consumers with rival companies, materials, resources of equipment and parts, government restrictions, and the amount of change of the market's preference of the product.

Purpose : This study was to investigate the application of Rhythmic Initiation(RI) in the respect of information processing in motor learning. Methods : A computer-aided literature search was performed in PubMed and adapted to the other databases and the others were in published books. The following keywords were used: Rhythmic Initiation, attention, memory, motor accuracy, feedback, motor learning, motor control, PNF, cognition. Results : The characterization of RI is rhythmic motion of limb or body through the desired range, starting with passive motion and progressing to active resisted movement. This study suggested that the relationship between of RI and motor learning through the respect of information processing, memory, attention and motor accuracy. Conclusion : Only Rhythmic Initiation, specifically focused on the effects of information processing approach, suggesting that RI can be positively influeced on sensory-perception, attention, memory, motor accuracy. however, it is unclear whether positive effects in the laboratory and field can be generalized to improve. In addition, sustainability of motor learning with RI remains uncertain.

Writing is an indispensable skill among the four language skills, but in actual teaching, it is also a difficult part to master for students. To improve students' writing ability, it is very important to understand their cognition and attitude towards writing. Because students are the main body of learning, learning and teaching are complementary to each other. Comprehending students' opinions is very significant for improving teaching. For this, the purpose of this paper is to investigate the perception and attitudes of Korean college students towards Chinese writing de ply, and based on the results of the survey, this study also suggested several proposals. As one of the basic researches of writing teaching design, this paper provides a certain reference basis of future instructional curriculum designs.

뉴스 이용 경로가 오프라인 신문에서 온라인 뉴스 매체로 이동하면서, 새로운 여론 형성의 기제로 대두된 댓글에 대한 연구가 많이 이루어져왔다. 댓글에 대한 연구는 주로 댓글의 품질이나 영향력 유무, 여론 형성 기능 등을 중심으로 이루어져왔다. 그런데, 댓글의 여론 형성 기능에 대한 연구 외에, 정치적 민감도가 높은 이슈에 대한 매체별 논조와 개인의 정치성향에 따른 연구는 찾아보기 힘들다. 특히, 이용자의 사회정체성과 정치성향이 그들의 매체선택과 해당 매체에서 접하는 댓글에 대한 인식에 어떠한 영향을 미치는지에 관한 연구는 거의 없었던 것으로 보인다. 이에 본 연구는, 이용자들이 온라인 뉴스 매체와 자신의 정치성향이 유사한 정도에 따라 해당 댓글의 신뢰도, 영향도 등을 다르게 평가하는지에 대해 사회 정체성 이론의 관점에서 살펴보았다. 이를 위해 '개인과 온라인 뉴스 매체 간 정치성향의 유사성'을 독립 변수로 놓고 '댓글에 대한 일반적인 인식'과 '정치성향이 각기 다른 매체의 댓글에 대한 인식'을 종속 변수로 하여 양 변수의 관계를 분석하였다. 동 연구는 댓글 읽기에 초점을 두고 처음으로 정치성향에 따른 매체 이용 패턴과 댓글에 대한 인식을 연구하여 분석했다는 데 학문적 의미를 찾을 수 있을 것이다. 또한, 온라인 뉴스 매체별 댓글 인식의 차이는 댓글 읽기의 중요성과 공론장으로서의 댓글이 유효함을 증명한데 그 의미가 있다.

SAFRS is the system designed to reproduce the harmonic sound into the space according to the environmental factors. Here the harmonic sound means the sound which judged by the subjective tests, and the methods were suggested in the former studies. In this research, SAFRS was applied into the Square of D University to evaluate and verify the effectiveness of the system and a few evaluations were carried out as follows; 1) sound perception, frequency, volume and harmony with the space, 2) images of the square and acoustic environment and 3) acoustic environment with existing sounds, fountain sound, produced sound by SAFRS, and both of them respectively. The results can be summarized as follows; 1) According to the evaluation on acoustic environment, no relationships were shown between the cognition of sounds produced by SAFRS and the frequency or volume, but inverse proportion was shown between the volume and special harmony. 2) As the result of image evaluation. the relationship between space and sound image was shown proportional only except the evaluation on main road at night time, it means that the sound proposal with the visual contents matching with the sounds would be more effective than the proposal of sound only. 3) Results of evaluation on acoustic environment showed that the cognition effect at night time was shown higher than that of day time when only the acoustic element was given and the effect was increased when the visual elements matches with the acoustic elements if both of them were given. It confirmed the harmony between visual and acoustic elements was very important.
