새로운 주제의 탐지를 위한 여러 접근법들을 지식 구조 표현 방법 중 하나인 디스크립터의 부여 및 갱신 과정에 적용하였다. 새로운 주제 탐지는, 특히 특정 학문 분야에서 새로운 주제의 출현 및 성장으로 인하여 지식구조상의 변화가 발생하는 경우에, 기존의 색인어로는 이를 표현할 수 없거나 표현상의 제한이 따르는 문제를 해결하는 데 응용할 수 있다. 실험 결과, 정보학 내에서 긍정적 측면의 변화가 발생한 것으로 식별된 신흥 주제들은 상당수가 서로 밀접하게 연관되어 있으면서 동시에 성장${\cdot}$발전의 단계에 있는 주제임을 확인하였다. 또한, 새로운 주제 탐지를 통한 후보 디스크립터 리스트의 사용이 색인자의 색인작업을 지원하는 효율적인 도구가 될 수 있다는 가능성을 보여 주었다. 특히, 적절한 디스크립터의 선정과 부여를 위한 후보 디스크립터 리스트의 제공은 색인작업의 효율성과 정확성을 향상시키는 데 기여할 수 있을 것이다.

정보교과에서 정보의 표현과 자료구조에 대한 이해는 컴퓨터과학의 기본원리에 대한 기초단계교육이라 할 수 있다. 그러나 자료구조가 정보교과에서 갖고 있는 교육적 함의나 학생들에게 성찰을 제공하기 위해 어떤 형태로 구성되어야 하는지에 대한 연구는 이루어지지 않았다. 따라서 본 논문은 2007 개정 교육과정을 기초로 제작되어, 2010년부터 사용되고 있는 정보교과서 '정보의 표현과 관리'영역의 탐구적 경향을 분석하였다. Romey 분석법으로 분석한 결과, 본문 분석, 학습자료 분석, 학습활동 분석, 장이나 절에 대한 분석에서 탐구적 경향을 보인 교과서는 1개로 나타났다. 교과서가 지식을 전달하는 데 집중하면, 학생들을 학습에서 소외시킬 수 있다. 특히 정보교과의 경우, IT를 활용한 문제해결에 기저가 되는 교과이므로 학습에서 소외된 학생들은 다양한 문제해결의 과정에서 박탈될 수 있음을 고려해야 한다는 시사점을 제공하였다.

건축디자인을 평가하는 방법에는 상당히 맡은 요소를 고려 할 수 있다. 기능성, 구조성, 형태, 환경 등 다양한 요소를 고려하여 최종의 디자인을 생산해 낸다. 여기서 computer와 같은 자동화된 기계에 의해서 디자인이 생성된다면, 그 결과는 경우에 따라서 무수히 맡아 우리 인간의 평가 능력 범위를 넘는 수 가 있다. 따라서 디자인을 자동으로 생산할 뿐 만 아니라 자동으로 최선의 결과물을 자동적으로 평가하여 선택하는 것도 상당히 중요하다. 본 논문에서는 상기에서 언급한 요소 중 미학적 특성을 기계가 자동으로 평가하여 최적의 결과물을 선택할 수 있도록 평가 방법을 제시하였다. 평가 방법은 고전적으로 내려오는 미적 평가방법의 하나인 질서와 무질서의 상관 관계를 측정하는 것으로 이는 형태요소와 공간관계를 나타내는 형태 디자인 지식의 스키마적 표현을 적용한다.

Currently, XML and its schema language have become the standard for data representation and information exchange format on the current web. Unfortunately, problems happen when integrating different data sources since XML mainly supports the document structure but lack consideration on sharing knowledge of data. Meanwhile, Semantic Web technologies, such as Web Ontology Language (OWL), can include the structure as well as the semantics of the data. Therefore, finding a way to integrate XML data as OWL ontology receives a high interest nowadays. In this paper we present a mapping notation to convert XML Schema to OWL domain knowledge and an effective method to transform XML instances into OWL individuals. While keeping the XML original structure, our work also adds more semantics for the XML document. Moreover, whole of the transformation processes are done automatically without any user interference. Further, our transforming approach provides the solution for duplicate element names in XML document which has not mentioned in the previous work. Our results in existing OWL syntaxes can be loaded immediately by OWL editors and Semantic Web applications.

In these days everyone search the information easily with the Internet as the rapid distribution and active usage of the Internet. The search engines were developed specially to accuracy of information retrieval. User search the information more quickly and variously with them. The search portal system will be embossed with representation and basic services. The Internet user needs the result of text, image and video, knowledge search. The keyword based search is used generally for getting result of the information retrieval and another method is category based search. This paper investigates the classification of knowledge search structure for oriental medicine in market leader of search portal system by ranking web site. As a result, each classification system is unified and there is a possibility of getting up a many confusion to the user who approaches with classification systematic search method. This treatise proposed the improved oriental medicine classification system of internet information retrieval in knowledge search area. if the service provider amends about the classification system, there will be able to guarantee the compatibility of data. Also the proper access path of the knowledge which seeks is secured to user.

Conventional expert systems have difficulties in the inference on time-varing situations because they don't have the structure for processing time related informations and rule representation method to describe time explicitely. Some expert systems capable of temporal reasoning are not applicable to the domain in which state changes happen by unpredictble events that cannot be represented by periodic changes of data. In this paper, an event based temporal reasoning method is proposed. It is capable of processing te unpredictable events, representing the knowledge related to event and time, and infering by that knowledge as well as infering by periodically time-varing data. The NEO/temporal, an temporal inference engine, is implemented by applying the proposed temporal reasoning situation assessment and decision supporting system is implemented to show the benefits of the proposed temporal information processing model.

`Desire` in this study is not something desire in the used to be-way we can deal with it. This study is to figure out 'desire structure' of interior architecture as a significant measure to interpret the Lacan's desire theory. It is also examines Lacan's concept of desire as defined in the mechanisms of language, in relation to architecture and interior architecture, and in the concept of the objet a(the unattainable object of desire), in the structure of desire as it can be seen in interior architecture. In particular, it analyzed that the desire structure have influenced on some kind of specific desire types what is expressed a characteristic to interior spaces of intimacy, perpetuity, representation, expression. These types reveal the characteristics of desire structure in inner space of interior architecture through negativing and fantasying. The focus on the structure becomes a major issue in almost many kinds of contemporary knowledge-system that starts from the mind to go out to the space in a material or non-meterial(spiritual) way. Therefore, the desire structure reconstructs the Real to make itself through negative and fantastic creation-process. It is important that desire characteristics help detect behind beneath the singularity of interior spaces more than what we know.

In a power plant, disturbance detection and diagnosis are massive and complex problems. Once a disturbance occurs, it can be either persistent, self cleared, cleared by the automatic controllers or propagated into another disturbance until it subsides in a new equilibrium or a stable state. In addition to the Physical complexity of the power plant structure itself, these dynamic behaviors of the disturbances further complicate the fault monitoring and diagnosis tasks. A data structure called a disturbance interrelation analysis graph(DIAG) is proposed in this paper, trying to capture, organize and better utilize the vast and interrelated knowledge required for power plant disturbance detection and diagnosis. The DIAG is a multi-layer directed AND/OR graph composed of 4 layers. Each layer includes vertices that represent components, disturbances, conditions and sensors respectively With the implementation of the DIAG, disturbances and their relationships can be conveniently represented and traced with modularized operations. All the cascaded disturbances following an initial triggering disturbance can be diagnosed in the context of that initial disturbance instead of diagnosing each of them as an individual disturbance. DIAG is applied to a typical cooling water system of a thermal power plant and its effectiveness is also demonstrated.

Many topics in science, especially, abstract concepts, relationships, properties, entities in invisible ranges, are described in mathematical representations such as formula, numbers, symbols, and graphs. Although the mathematical representation is an essential tool to better understand scientific phenomena, the mathematical element is pointed out as a reason for learning difficulty and losing interests in science. In order to further investigate the relationship between mathematics knowledge and science understanding, the current study examined 793 high school students' understanding of the pH value. As a measure of the molar concentration of hydrogen ions in the solution, the pH value is an appropriate example to explore what a student mathematical structure of logarithm is and how they interpret the proportional relationship of numbers for scientific explanation. To the end, students were asked to write their responses on a questionnaire that is composed of nine content domain questions and four affective domain questions. Data analysis of this study provides information for the relationship between student understanding of the pH value and related mathematics knowledge.
