The development of computer-based modeling system has allowed the operationalization of cognitive science issues. Human cognition has become one of most interesting research subjects in artificial intelligence to emulate human mentality and behavior. This paper introduces a methodology well-suited for designing the intelligent system of human cognition. The research investigates how to elicit and represent cognitive knowledge obtained from individual city-dwellers through the application of fuzzy relational theory to personal construct theory. Crucial to this research is to implement formally and process interpretatively the psychological cognition of urbanites who interact with their environment in order to offer useful advice on urban problem. What is needed is a techniques to analyze cognitive structures which are embodiments of this perceptive knowledge for human being.

본 연구는 기술수용모델(Technology Acceptance Model)을 기반으로 <클림트 인사이드(2017)>전시에서 사용된 <스토클렛 저택의 장식벽화(Stoclet Frieze)> VR 앱에 대한 인지된 유용성(이하 PU)과 인지된 이용용이성(이하 PEOU)의 평가에 초점을 맞추었다. VR 앱의 학습적합성(SFL)이 감상적합성(SFA)보다 높게 평가된 PU의 경우, 학습유용성(UFL)과 감상유용성(UFA)의 모든 요인이 만족도(DOS)에 긍정적인 영향을 미침으로써, 전시환경에서의 VR 앱의 학습에 대한 내적 동기 부여 및 감상 지원에 대한 잠재력이 확인되었다. 또한 PEOU의 모든 요인들은 DOS뿐만 아니라 DOI와도 유의미한 상관관계를 가졌다. 본 연구를 통해 TAM의 PU와 PEOU의 ATUA(DOS 및 DOI) 및 BITUA(ITRA(1) 및 ITRA(2))에 대한 영향력이 검증됨에 따라, 두 변수는 사용자의 VR 앱에 대한 기술 수용에 대한 예측을 가능케 했으며, 결론적으로 예술작품 원작을 재매개한 VR 앱에 대한 평가모델로써 TAM의 적합성이 입증되었다.

Theory of mind (ToM) is the ability to infer one's own and other people's mental states such as beliefs, desires, and intentions. Although the majority of research in ToM has focused on young children or autistic individuals, several studies have investigated ToM in normal old age and in the demented elderly. This article provides an overview on existent findings of theory of mind in aging populations and suggests future directions for research including applying neuroimaging techniques and real-life tasks. It is still unclear how ToM in aging is associated with other aspects of cognition. However, it is expected that ToM perspective on aging will increase our understanding of aging of cognition and social functioning.

The statistical graphics is a design field focusing on the user perception aspects for the correct information delivery and the effective understanding, with the use of the quantitative data through the information analysis, extraction, visualization process. The statistical graphics with the big data composition factor is termed as the statistical big data graphics. In the statistical graphics the visual factors are used to reduce the errors in the perception part and to successfully deliver the information. However, in the statistical big data graphics the visual factors of the enormous data are causing the cognitive discouragements. The purpose of this study is to extract the cognitive discouragement factors from the big data statistical graphics, categorizing the types of the statistical big data graphics as 'network type', 'segment type', and 'mixed type', based on their compositional shapes, and explored the characteristics according to them. Especially, based on the visual main factors in the statistical big data graphics, We extracted the cognitive discouragement factors that appear in the high visualization as the four categories: 'multi-dimensional cases', 'various color', 'information overlap', and 'legibility of the writing'.

Based on conceptual change theory, cognitive conflict is known as an important factor for conceptual change even though there are still questions about its positive and negative effects on science learning. However there are little research which propose types of meaningful(constructive) cognitive conflict in learning science. The purpose of this study is to find out how are the anxiety types of cognitive conflict to which high school students respond in the action-reaction task, and to reveal what's the characteristic of the explanatory hypothesis according to the anxiety types. The result of this study indicated that first, the characteristics of the anxiety types of the cognitive conflict were classified as eight types. Especially the students who belong to the types of conviction of logical misconception and reasonable modification suggested explanatory hypothesis close to physical nature. On the other hand, the students who showed other types of anxiety except the two types of anxiety suggested temporary supported hypothesis or simple explanatory hypothesis based on students' observation and intuition. Finally we discussed the importance and the implication of the types of anxiety in applying the cognitive conflict strategy to science instruction.

The purpose of this study was to investigate and compare the risk factors of cognitive impairment between non-depressive elderly and depressive elderly. Data was obtained from 1,477 elderly not diagnosed to dementia. In result, non-depressive elderly group was found as having risk factors of cognitive function in age and educational level. In non-depressive group, older elderly(OR=1.095) and the elderly with no experience of education(OR=9.129) had more in risk of cognitive impairment. Depressive elderly group was found as having risk in age, educational level, and residence style. In depressive elderly, older elderly (OR=1.101), the person with low education(illiteracy:OR=33.020, elementary:OR=10.176, middle school: OR=9.841), and the elderly living in nursing home(OR=8.490) had more in risk of cognitive impairment. Through this result, it could be suggested that the depressive elderly with low educational level living in nursing home should be intervened to decrease the rate of dementia more effectively.

Posttraumatic stress disorder (PTSD) is well known to have a limited response to drug treatment. Many recently published clinical care guidelines recommend trauma-focused psychotherapies such as cognitive processing therapy (CPT) and prolonged exposure therapy (PE) as first-line treatment and medication such as serotonin reuptake inhibitors and venlafaxine as second-line treatment. Current review introduces the session composition and contents of CPT and presents various CPT studies that show therapeutic effect for civilian and veterans/military with PTSD. In order for clinicians to help effectively patients with PTSD, it is necessary to learn and actively use evidence-based trauma-focused psychotherapies including CPT and PE.

The purpose of this study was to analyse the belief about mathematics teaching of elementary preservice teachers and mathematics teachers. This study involved 100 respondents from the preservice teachers and 114 respondents from the mathematics teachers. The instruments used in this study consist 15 items of mathematical knowledges and 19 items of mathematical activities. The finding showed that preservice teachers emphasized the conceptual knowledge, whereas mathematics teachers emphasized the procedural knowledge in the mathematical knowledges. And preservice teachers emphasized the knowledge representation, knowledge generation, knowledge deliberation, knowledge communication, whereas mathematics teachers emphasized the use of knowledge(syntax) in the mathematical activities. Finally, even though two groups showed the significant difference in some items, preservice teachers and mathematics teachers emphasized the various mathematical knowledges and mathematical activities.

오늘날 스마트 홈은 네트워크 센서, 가전 기기 등에 자동화된 서비스를 부여하여 사용자의 인지 없이 지능형 서비스를 제공하는 것이 목적이다. 이와 같은 지능형 홈 네트워크 서비스를 제공하기 위한 기존의 연구들은 온톨로지 기반의 컨텍스트 모델을 통해서 시맨틱 컨텍스트 표현, 추론, 지식 공유를 통해서 자동화된 서비스를 제공하는데 초점을 두고 있다. 그러나 이러한 연구들은 장치가 제공하는 서비스에 대한 자동화에 초점을 두고 있지만 진정한 지능형 홈 네트워크 서비스는 사용자의 다양한 패턴에 따라서 시간순으로 서비스를 자동으로 제공해야만 한다. 이러한 관점에서 본 논문은 사용자 패턴에 따른 자동화된 서비스를 사용자에게 지능적으로 제공하는 지능형 흠 네트워크 서비스를 제공하는 시스템 설계에 초점을 둔다. 이러한 자동화된 서비스를 제공하기 위하여 본 논문은 데이터 마이닝 기법을 사용하여 사용자 패턴 분석 기법을 제안할 것이다.
