  • Clinical neuropsychology which belongs to the necuroscience field is concerned with relationship between human behaviors and the brain structure. Clinical neuropsychology has grown to be a specialized separate field within psychology over the last twenty years. Clinical neuropsychology offers an objective methodology to consider the mind-body interaction and evaluate the behavioral consequences and functional deficits associated with brain lesions. Clinical neuropsychological assessment is composed of cognitive, perceptual, motor and emotional function through various neuropsychological examinations such as Halsted-Reitan and Luria-Nebraska batteries, and computerized neuropsychological test such as PCIS Vienna Test System and Stim. The goals of neuropsychological evaluation are to identify of neuropsychological dysfuncitions, to develop execute and monitor treatment plans, and to make rehabilitation programs. Recently, the neuropsychiatric patients are increasing in number and 15-20% of acute psychiatric patients suffer from organic mental problems. Moreover, clinical neuropsychology has an increasingly important role in both neurobehavioral foundation and clinical application. So, psychiatrists must play a major role in the development of clinical neuropsychology in psychiatry.

  • In this paper, we address two questions concerning negative imperatives in Korean: (i) what is the morpho-syntactic nature of mal in negative imperatives\ulcorner; and (ii) why is it impossible to form negative imperatives with short negation an\ulcorner We will argue that the clause structure of imperatives include a projection of deontic modality and a projection of imperative operator encoding illocutionary force, and that oaf is a lexicalization of long negation and deontic modality. We then propose that a negative imperative with short negation is ruled out because such construction maps onto incoherent interpretation which can be spelled out as I direct you to bring about a negative state or a negative event.

  • This study applies factor analysis of an author cocitation frequency matrix derived from a database file that consists of a total of 1095 cited reference records taken from 95 citing decision support systems articles published in Korean journals. This study identified the influence of social psychology, cognitive psychology, management information systems, strategic management, and organizational behavior/organizational design to the development of group support systems, user-interface, and executive information systems research subspecialties. This research establishes a benchmark to be used in the future research, which is necessary to account for the ongoing changes in the intellectual development and structure of DSS Research in Korea before solid conclusion can be reached about the maturity and on-going development of the DSS field in Korean.

  • 본 연구는 단일 문서로부터 문서가 내포하고 있는 지식정보를 지식구조 혹은 인지스키마로 불리는 형태로 자동 생성하는 기법을 제안한다. 제안된 기법을 이용하여 자동 생성된 지식구조는 실제 문서 학습자의 학습 전, 후의 지식구조, 문서의 해당 지식을 명확히 알고 있는 도메인 전문가의 지식구조와의 유사도 측정을 통해 검증하였다. 자동 생성된 지식구조는 학습자의 학습 후 지식구조, 전문가 지식구조와 상당한 유사성을 보이며, 문서의 지식 정보를 인지적인 관점에서 정교하게 표현 하고 있음을 확인하였다. 이는 기존의 단어 기반의 정보 기술들에서 더욱 고차원적인 지식 정보를 활용한 지식구조 기반 정보 기술의 연구 가능성을 제시한다.

  • This study examined individual differences in navigating in hyperspace learning environment where a minimum structure is provided. Using a hypercard stack called "Pearl Harbor", Field Dependent people used guidance more often than those in Field Indepedent; FI achieved scored higher at the end of the study; and FI people had some type of pattern showing from them audit trail when FD people did not show any trail of patterns. Also people with higher visual thinking scores achieved higher scores in hyperspace environment.

  • 인터넷은 다양한 언어로 구성된 정보를 사용자들에게 제공해 준다. 따라서 인터넷 환경상의 정보 다국어화는 앞으로도 점차 가속화될 것으로 보인다. 그러나 각 국가별 지역 코드는 다국어 정보화를 가로막는 하나의 걸림돌이 되고 있다. 본 논문에서는 실사용자(end-user)와 개발자(developer) 환경에서 발생하는 다국어 지원의 문제점에 대해 알아보고, 이를 부산대학교 언어 정보 연구실에서 연구중인 다국어 지원 방법과 연관하여 특히 웹 환경에서 다국어가 동시에 지원될 수 있는 방안에 관해 연구하였다. 한글 환경에서 다국어가 원활히 지원되기 위해서는 유니코드 도입과 함께 다국어 입력 알고리즘이 개발되어야 하며, 이에 따른 다국어 입력 컨트롤 및 라이브러리 개발이 선행되어야 한다. 또한 웹 환경에서도 KS-C-5601 기반이 아닌 Unicode 기반 웹 환경 구축이 진행되어야 할 것이다.

  • 이 연구에서는 국내 인지과학 분야의 연구자 소속 정보와 논문의 표제어 분석을 통해 학제적 구조 파악을 시도해 보았다. 연구 결과 국내 인지과학 분야에서 대표되는 학문 영역은 컴퓨터과학, 심리학, 언어학, 인지과학, 철학, 교육학, 의학, 경영학이었다. 두 시기(1기: 1989-1998, 2기: 1999-2003)로 구분하여 분석한 결과 국내 인지과학 분야는 1기에서는 컴퓨터과학, 심리학, 언어학 순으로 우세한 학문분야가 나타났다. 이와 달리 2기에서는 심리학, 컴퓨터과학, 인지과학, 언어학의 순이었다. 이 같은 결과는 컴퓨터과학의 비중이 초기에 가장 높다가 감소했다는 점에서 외국의 사례와 유사하지만, 외국에 비해서 언어학 분야 연구자의 비중이 다소 높은 것이 국내 인지과학 연구의 특징인 것으로 나타났다. 연구자가 사용한 표제어를 분석한 결과 두 시기에서 모두 컴퓨터과학과 심리학은 인지과학분야에서 융합되기 보다는 독자적인 연구영역을 형성하였다. 또한 시기별 표제어 분석을 통해서 컴퓨터과학이나 심리학 소속 인지과학 연구자들의 관심사가 1기에서 2기로 넘어가면서 변화한 부분을 확인할 수 있었다.

  • The present study employed an experimental usability testing technique to explore cognitive engineering characteristics of WWW. Based on the results of our previous study which employed non-experimental methods such as questionnaire and heuristic evaluation method, this study used a behavioral performance-measurement technique to evaluate the usability of a domestic web-site design. Specifically, we revised the menu and document structure of the original 'Movie-Friend' site to solve the design problems which were extracted from the results of the heuristic evaluation method of our previous study. Exp. 1 compared the relative navigation efficiency of the original frame menu site and the revised pop-up toolbar site, and Exp. 2 compared the toolbar menu site and the revised frame site. As a result of Exp. 1, the revised pop-up toolbar site showed improved navigation efficiency compared to the original site, as indicated by the mean latency and the number of pathways to reach the target page. However, we found no performance difference between the frame site and toolbar site in Exp. 2.

  • Fragile X syndrome (FXS) is caused by a lack of the fragile X mental retardation protein (FMRP) due to silencing of the Fmr1 gene. As an RNA binding protein, FMRP is thought to contribute to synaptic plasticity by regulating plasticity-related protein synthesis and other signaling pathways. Previous studies have mostly focused on the roles of FMRP within the hippocampus - a key structure for spatial memory. However, recent studies indicate that FMRP may have a more general contribution to brain functions, including synaptic plasticity and modulation within the prefrontal cortex. In this brief review, we will focus on recent studies reported in the prefrontal cortex, including the anterior cingulate cortex (ACC). We hypothesize that alterations in ACC-related plasticity and synaptic modulation may contribute to various forms of cognitive deficits associated with FXS.

  • Isoflavones are phytoestrogens and natural plant compounds which are similar to 17-${\beta}$-estradiol in chemical structure. It is known that they can act as estrogen agonists or antagonists, depending on endocrine estrogenic levels, but actions of isoflavones are rather complex due to large number of variables such as chemical structures and mechanisms. Some hypotheses on biological mechanisms have not satisfactorily been confirmed to date and human epidemiological and experimental studies have been relatively limited. Nevertheless, isoflavones and isoflavone rich foods have become a focus onf interest due to positive health benefits on many diseases, especially prevention of hormone-related cancers, cardiovascular disease, osteoporosis, and adverse postmenopausal symptoms, and improvement of physiological condition such as maintaining cognitive function. This review provides an overview of chemistry, analytical techniques (focused on human biospecimens), functions including biological mechanisms, and effects of isoflavones, on the basis of the available meta-analysis and review articles and some original articles, on health and cancer.
