  • Ever since the dawn of civilization, the ambient vegetation and the resources constituted major source of human existence for various substantial requirements. Our present knowledge on plant resources emerged from the traditional heritable knowledge descended from generation to generation. However, traditional knowledge pertaining to several aspects remained untapped from various remote localities or populations. Furthermore, with the present trends of excessive exploitation of natural resources and degradation of habitats, conservation and ecological management require coherence of traditional skills and modern approaches. Therefore, the present study is to record traditional plant based knowledge among the inhabitants of Siwalik region of Uttarakhand Himalaya. Extensive field survey was made for the collection of data on the medicinal aspects of plant species in the study area covering the parts of districts Pauri, Dehradun and Haridwar. During the course of study 130 plant species belonging to 65 families are reported, used as traditional medicine by the local inhabitants of this region.

  • 이 연구는 영재학생들이 작성한 탐구수행일지에서 나타나는 지식생성과정을 분석한 것이다. 분석한 결과, 첫째, 영재학생들은 다양한 지식생성과정을 보여 주었으나, 귀납적 과정과 귀추적 과정이 대부분이었으며, 그 또한 매우 단순한 사고과정만을 보여주었다. 둘째, 영재학생들의 지식 생성 과정은 제한된 범위의 관찰과 경험 상황을 바탕으로 한 단순 반복적인 도식적 문답 과정이 많으며, 단순 반복적인 도식성은 간단한 변인 선택 및 고안, 제한된 범위의 관찰, 주관적 사고로 인한 편견 개입, 탐색이나 결점 찾기 등이 잘 이루어지지 않아 발생하는 것으로 생각되며 이와 더불어 추론의 비약이 자주 나타났다.

  • 향후 여론의 주도층이 될 일부 초, 중, 고등학생을 대상으로 방사선이용 분야 중 일반적으로 사회적 수용성이 절실히 필요한 방사선조사식품, 원자력발전, 의료방사선에 대한 인식, 지식 및 태도를 설문 조사한 결과 사회적 수용성 증진을 위한 교육적 근거가 일부 도출되었다. 첫째, 여학생 중심의 수업과 남학생 중심의 수업설계에 차별화된 전략이 필요하다. 여학생 보다 남학생이 방사선조사식품의 객관적 지식수준(p<0.039), 원자력발전의 필요성(p<0.001) 및 객관적 지식(p<0.001), 우리나라 원자력발전소 건설 찬성태도 (p<0.000), 의료방사선의 필요성(p<0.001) 및 객관적 지식(p<0.001), 의료방사선 이용 태도(p<0.007, p<0.001)가 모두 높기 때문이다. 둘째, 원자력발전의 필요성, 안전성에 대한 국민 이해를 돕기 위한 설명에서는 의료방사선의 필요성과 안전성에 대한 정보를 함께 제공하는 것이 교육효과를 높일 수 있다. 남, 여학생 모두 의료방사선이 가장 필요하며(p<0.001), 의료방사선이 가장 안전하며(p<0.001), 원자력 발전이 가장 안전하지 않다고(p<0.013) 인식하고 있다. 또한 의료방사선과 원자력 발전의 상관관계가 가장 높게 나타났기 때문이다. 셋째, 초, 중, 고등학생이 방사선이용 분야별로 인식의 패턴이 다르므로 학급별로 차별화된 강의내용이 필요하다. 초등학생은 원자력발전에 대한 교육흥미도가 높고(p<0.005), 방사선조사식품이 안전하다고 인식하고 있으며(p<0.001), 방사선조사식품을 섭취하겠다는 태도가 가장 높았다(p<0.001). 중학생은 의료방사선에 대한 교육흥미도가 높고(p<0.018), 원자력발전(p<0.001)과 의료방사선(p<0.002)에 대해 안전하다고 인식하고 있으며, 치료 방사선이용 태도가 가장 높았다(p<0.001). 고등학생은 원자력발전(p<0.001)과 의료방사선(p<0.001)에 대한 객관적 지식수준이 가장 높고, 의료방사선이 가장 필요하다고 인식하고 있으나(p<0.017), 원자력발전이 가장 안전하지 않다고 인식하고 있다(p<0.001). 방사선조사식품 섭취 태도(p<0.001), 거주지에 원자력발전 건설을 찬성하는 태도(p<0.001) 모두 낮았다. 넷째, 객관적 지식 중심의 교육제공보다 인식변화 및 태도증진을 위한 교육프로그램이 제공되어야 한다. 객관적 지식과 방사선조사식품의 필요성, 객관적 지식과 원자력발전에 대한 안전성 및 교육흥미도, 객관적 지식과 의료방사선의 교육흥미도 및 정보습득에는 상관관계가 없었다. 특히, 고등학생의 경우 객관적 지식수준은 가장 높았으나 거주지의 원자력발전 건설에 대해 찬성하는 태도와 방사선조사식품 섭취태도가 가장 낮았기 때문이다. 국내에서 원자력 및 방사선이용에 대한 사회적 수용성을 향상시키기 위해 필요성과 안전성에 대한 인식과 지식 및 태도 향상에 관한 교육프로그램을 전략적으로 제공하는 것이 바람직하다.

  • Today, Internet users start off using heavily SNS(Social Network Site) such like, Facebook, Twitter. The reason of the growth of using SNS would be closely related to the various services of gaming, playing, entertainment items, sharing information etc., provided by the SNS, technically, the most important one out of the services provided would be behaving of sharing knowledge among people who connected and networked in the site. In sum, we assume that the users may communicate well each other and pay attention to build closely a social network using that kind of activities. However, nevertheless the new trends of communications and sharing knowledge become popular, researchers have just began the research issues in explaining why Internet user rush into SNS and enjoy the time in there. Therefore, we investigate on the reasons of posting knowledge voluntarily in the SNS and how others response to the posted information and actually affected by the behavior. We appled personal relation and social identity theory for this study, which personal relation in SNS may affect on social identity and make them produce knowledge generation. We found that social identity and involvement in SNS is closely related and influence knowledge creation and generation. This empirical study resulted in the importance of social relations in SNS, which leads to a sharing knowledge.

  • Most of existing expert systems developed for Web use CGI-based techniques and this frequently makes them suffer from the overburden of commercial Web servers, which deal with large-scale services. However, since HTML-based inference technique represents expert's knowledge by hyperlinks among HTML documents, the hypertext function of the Web can perform the inference efficiently in terms of time and space without the help of additional inference engines. In spite of such benefits, when the expert's knowledge is relatively large and/or complicated, the HTML-based inference technique has usually become to have a hard time of dealing with a lot of HTML documents because generation and management tasks of the numerous HTML documents would cause big trouble to the knowledge engineer. To resolve this problem, we developed an automatic generation and management tool for Web-based inference sites, called WeBIS. With this tool, a knowledge engineer can input and edit expert's knowledge using Expert's Diagram on the GUI(Graphical User Interface) environment and automatically generate hyper-linked HTML documents for Web-based inference from the Expert's Diagram.

  • The main purpose of this paper is to explore the role of meta-knowledge for knowledge creation and knowledge transformation in cooperative problem solving processes. For this I will discuss what the primary functions of meta-knowledge are from the knowledge representation perspective. The proposed theoretical model is useful to develop a new form of knowledge management support systems beyond the first generation of knowledge-based systems.

  • Knowledge discovery in databases(KDD) is the process for extracting valid, novel, potentially useful and understandable knowledge form real data. There are many academic and industrial activities with new technologies and application areas. Particularly, data mining is the core step in the KDD process, consisting of many algorithms to perform clustering, pattern recognition and rule induction functions. The main goal of these algorithms is prediction and description. Prediction means the assessment of unknown variables. Description is concerned with providing understandable results in a compatible format to human users. We introduce an efficient data mining algorithm considering predictive and descriptive capability. Reasonable pattern is derived from real world data by a revised neural network model and a proposed fuzzy rule extraction technique is applied to obtain understandable knowledge. The proposed neural network model is a hierarchical self-organizing system. The rule base is compatible to decision makers perception because the generated fuzzy rule set reflects the human information process. Results from real world application are analyzed to evaluate the system\`s performance.

  • Knowledge based system includes tools for constructing, testing, validating and refining the system along with user interfaces. An important issue in the design of a complete knowledge based system is the ability to produce explanations. Explanations are not just a series of rules involved in reasoning track. More detailed and explicit form of explanations is required not only for reliable reasoning but also for maintainability of the knowledge based system. This requires the explanation mechanisms to extend from knowledge oriented analysis to task oriented explanations. The explicit modeling of problem solving structures is suggested for explanation generation as well as for efficient and effective reasoning. Unlike other explanation scheme such as feedback explanation, the detailed, smaller and explicit representation of problem solving constructs can provide the system with capability of quality explanation. As a key step to development for explanation scheme, the problem solving methods are broken down into a finer grained problem solving primitives. The system records all the steps with problem solving primitives and knowledge involved in the reasoning. These are used to validate the conclusion of the consultation through explanations. The system provides user interfaces and uses specific templates for generating explanation text.
