  • The interface of computer software has to promote human-computer interaction. The one quality of interface to promote HCI should be evaluted with regard to user's information processing. The usability of interface is one of the main components of it's quality, and it is straightforwardly concerned with learnability, especially when users want to use a software at the first stage. In this paper, word processors, wide spreadly used in OA environments is studied in respect to menu structure on the interface. An cognitive menu structure is suggested by user's conceptual network of the main functions of word processor. Two word processors is selected to compare with the cognitive menu structure and to evalute learnabilities by teaming model.

  • One of the characteristics of the neurons that distinguishes them from other cells is their complex and polarized structure consisting of dendrites, cell body, and axon. The complexity and diversity of dendrites are particularly well recognized, and accumulating evidences suggest that the alterations in the dendrite structure are associated with many neurodegenerative diseases. Given the importance of the proper dendritic structures for neuronal functions, the dendrite pathology appears to have crucial contribution to the pathogenesis of neurodegenerative diseases. Nonetheless, the cellular and molecular basis of dendritic changes in the neurodegenerative diseases remains largely elusive. Previous studies in normal condition have revealed that several cellular components, such as local cytoskeletal structures and organelles located locally in dendrites, play crucial roles in dendrite growth. By reviewing what has been unveiled to date regarding dendrite growth in terms of these local cellular components, we aim to provide an insight to categorize the potential cellular basis that can be applied to the dendrite pathology manifested in many neurodegenerative diseases.

  • This paper reviewed models to explain memory and neuropsychological tests to assess memory. Memory was explained in cognitive and neuroanatomical perspectives, Cognitive model describes memory as structure and process. In structure model, memory is divided into three systems: sensory memory, short-term memory(working memory), and long-term memory. In process model, there are broadly three categories of memory process: encoding, storage, and retrieval. Memory process work in memory structure. There are two prominent models of the neuroanatomy of memory, derived from the work of Mishkin and Appenzeller and that of Squire and Zola-Morgan. These two models are the most useful for the clinician in part because they take into account the connections between the limbic and frontal cortical regions. The major difference between the two models concerns the role of the amygdala in memory processess. Mishkin and his colleagues believe that the amygdala plays a significant role while Squire and his colleagues do not. The most popular and widely used tests of memory ability such as WMS-R, AVLT, CVLT, HVLT. RBMT, CFT, and BVRT-R, were reviewed.

  • 개별화 학습은 단지 하나의 교수 학습 방법으로서의 의미가 아니라는 인식이 보편화되어 교실 수업뿐만 아니라, 성인 교육, 기업 교육 등 다양한 교수 학습 상황에서 관심을 끌어왔다. 한편 효과적인 개별화 학습은 학습자 특성에 대한 정확한 분석 및 측정이 필수적으로 요구되나, 학습자 특성에 대한 개념과 범주가 다양하고 광범위하여 그에 대한 계량적인 기술이 어렵다. 이에 본 연구에서는 학습자 특성을 인지구조와 인지양식으로 제한하였다. 또한 학습자 특성을 연결주의적 관점에서 기술하고 이를 기반으로 하여 학습자 특성의 정량화 기법을 제안하며 그에 대한 타당성을 검증하였다. 본 연구에서의 학습자 인지구조는 기존에 연구된 학습자 인지구조 객체를 간소화하였고 인지양식은 학습자 인지의 지식관성력으로 축소하여 기술하였다.

  • 본 연구는 인지과학으로부터 몇 가지의 이론을 이용하여 디자인의 사고과정 중의 일부를 설명함으로서, 인지과학으로부터의 지식을 디자인의 문제 해결에 응용하거나, 새로운 사고 발상 방법을 개발할 수 있는 가능성을 모색하기 위한 것이다. 디자인은 복합적이고 고도의 두뇌활동을 필요로 하는 영역이다. 그리고 인지과학은 인간의 두뇌활동을 연구하는 학문이다. 따라서 디자인과 인지과학의 연결은 디자인의 거의 전반에 걸쳐 응용될 가능성을 가지고 있다. 그 연결 가능성을 살펴보기 위하여 본 논문은 주로 아이디어 발상부분에 대한 사고의 과정을 인지과학으로 부터의 지식을 빌어 설명하여 보았다. 디자인의 프로세스와 사고 발상 과정을 인지과학의 지식구조에 대한 이론으로 해석해 본 결과, 디자인 사고 발상의 새로운 전개 가능성을 찾을 수 있었다.

  • This study was contrived Hierarchical Information Search (HIS) model. HIS model is based on a “cognitive process” in which model, comprising basic human information processing mechanize and information interaction. Its process include 3 semantic cognitive processes: Schema-Association LTM, Form Domain, and Alternative Selection. Design methodology consists to elicitate memory, thinking and cognitive response variables. In case study, menu structure of mobile phone was applied. In result, a correlation between predictive error rate and real error rate was .892. and a correlation between selective and real reaction time was .697. This present to suggest a model of how the methodology could be applied to real system design effectively when this was used. HIS model could become one of the most important factors for success of product design. In the perspective, the systemic methodology would contribute to design a quantitative and predictive system.

  • This study analyzed the process of information service and its factors in the cognitive viewpoint. And developed a conceptual model to help in developing future information systems and services. The results of this study were summarized as follows : 1) The paradigm of information user study is changing from the system-centered to the user-centered one. 2) The researchers describe the user's internal cognitive process as the starting point of the information service. 3) The user's personal cognitive process influence the process of the information service over. And the focus is a microscopic one including the factors of the perception and recognition of the stimulus, remembering and searching information, reasoning the rules, recognition of the patterns, formalization of the concepts, etc. 4) The information librarian performs the role as a knowledge/ information system interface, and his knowledge structure reflects the organization of that knowledge/information system. 5) The information librarians can perform their role as information specialists actively and offensively. And the performance of the librarians can be measured on the scales of the su n.0, pplying capability of relevant information and the client satisfaction.

  • This article examines how individual differences on the need for cognitive closure and demographics influence consumer perception and the usage of consumer reviews in online shopping. Data were randomly collected from 2,381 U.S. online consumer review users through an online survey. The findings from multiple regression analyses revealed the different effects of the need for cognitive closure dimensions (i.e., preference for order and structure, preference for predictability, discomfort with ambiguity, closed-mindedness, and decisiveness) and demographic characteristics on consumer attitudes, perceived online review influence, benefits, persuasiveness, and review usage behavior. Finally, practical implications and prospects for future research are discussed.

  • Child's temperament, cognitive ability, social competence, mother's affective child rearing and positive expression, father's positive expression, and teacher's positive expression were the variables investigated in relation to the structure of children's emotional competence (EC). Subjects were 20 teachers and 236 five-year-old children and their parents. Data were analyzed by LISREL (Linear Structural Relations), a statistical program for structural equation modeling. Results showed that boys' social competence and mother's affective rearing behavior directly influenced the EC of boys; boys temperament and cognitive ability, and positive expressions of their teachers indirectly influenced the EC of boys. Girls' temperament and social competence directly influenced the EC of girls; their cognitive ability, mother's affective child rearing behavior, and positive expressions of mothers and fathers indirectly influenced the EC of girls.
