This paper proposes an intelligent method for the optimal load distribution of two cooperating robots(TCRs) using fuzzy logic. The proposed scheme requires the knowledge of the robots' dynamics, which in turn depend upon the characteristics of large flat panel displays(LFPDs) carried by the TCRs. However, the dynamic properties of the LFPD are not known exactly, so that the dynamics of the robots, and hence the required joint torque, must be calculated for nominal set of the LFPD characteristics. The force of the TCRs is an important factor in carrying the LFPD. It is divided into external force and internal force. In general , the effects of the internal force of the TCRs are not considered in performing the load distribution in terms of optimal time, but they are essential in optimal trajectory planning: if they are not taken into consideration, the optimal scheme is no longer fitting. To alleviate this deficiency, we present an algorithm for finding the internal-force factors for the TCRs in terms of optimal time. The effectiveness of the proposed system is demonstrated by computer simulations using two three-joint planner robot manipulators.

From the study on A Study on A Study on Formation of Oriental Medicine Theory based on Analogical Inference, the conclusion is as follows. Analogical inference belonging to informal logic has very important point that it makes new knowledges of unknown field from basis of common knowledge field. The form of Analogical Inference is "A: a-B: (b)", In "Naegyeong(內經)", models of analogy are classified into two types. One is that of analogical inference making new knowledges in company with effects of Heung-gi(興起), Another is to unite common knowledges, While the example of analogy between military science and medicine belongs to type of the former, example of bureaucracy and medicine belongs to type of the latter, that based on rearrangement of common knowledge. Two type have similar system of national government or military management in basis. In such process of analogical inference, we expect that new knowledges of Oriental Medicine would be accumulated in the future, in the same way of the past.

이글은 불법적 호르몬 약물 소비행위라는 다소 이질적인 형태의 약물화(pharmaceuticalization) 현상에 주목한다. 운동선수들에게 아나볼릭스테로이드와 같은 호르몬 약물의 사용은 더 이상 생소한 일이 아니다. 거대한 근육을 획득하거나 힘을 증가시키기기 위해 운동선수들이 합성호르몬을 자신들만의 방식으로 사용하고 있다. 이러한 약물 사용 행위는 단순히 불법적인 것으로 볼 수 없다. 이들은 내분비계 전문의와 같은 의료전문가들과 대조되는 약물에 대한 지식을 형성하고, 합리적으로 약물을 소비한다. 의사들이 합성호르몬의 역할을 치료(treatment)에 한정지었다면, 약물 사용자들은 향상(enhancement)까지 확장시키고 있다. 합성호르몬의 새로운 역할에 가치가 부여되고 비공식적인 시장이 형성되고 있는 것이다. 이글은 생명정치와 생의료화의 비공식적인 현상으로 호르몬 약물 사용을 분석하고자 한다.

This research aimed for revealing social interaction-based environmental learning elements at the natural history museum. First, we carried out a survey of the perceptual change about 'the environment' concept. It was for confirming whether environmental learning occurred in visiting. Second, we found environmental learning elements through analyzing dialogues among small group members during looking around the museum. Social interaction-based environmental learning elements were classified into five; knowledge, affection, value, skill, behaviour. Each environmental learning element included several sub-elements, so we revealed totally 9 environmental learning sub-elements. By results, we said characteristics and possibility of the natural history museum as an informal environmental educational institution. It is meaningful for extending areas of environmental education.

In this case study, a professor was observed to investigate use of instructional examples when teaching the Intermediate Value Theorem in a calculus course. Video-recorded lessons were analyzed with constant comparison to video-stimulated recall interviews and field notes. The professor employed multiple instructional examples, which was initiated by students and modified by the professor. The professor asked students to build non-existing examples as an informal proof of the Intermediate Value Theorem and assessment of students' previous knowledge. Use of incorrect examples on instructional purpose can be an appropriate way for formative assessment as well as a bridge between informal and formal proofs in college mathematics.

This study explores visitor learning in a natural history museum from the perspectives of situated learning. The purpose of this study is to understand how the visitors construct knowledge from museum experiences through dyadic discourses. The participants were two university students. They moved naturally through the exhibition with no predetermined path in a natural history museum in Korea. Data were collected in the form of audio-recorded dyadic discourses at and between exhibits and were transcribed. The transcription was coded using the conversation coding scheme, and categorized into specific learning types. The findings included (1) the characteristics of learning talks and (2) learning types created by dyadic discourses at and between exhibitions within learning contexts as museum learning experiences. Implications and future research related to visitor learning in informal learning settings were discussed based on the findings.

The purpose of this study uses agricultural knowledge system theory to explore how the extension system in South Korea was developed and have worked well. By agricultural knowledge system we emphasized the dynamic networks of actors, processes of negotiation, and the diverse ways in which knowledge is constructed and performed. It was possible that individuals may participate in and utilize multiple knowledge systems. The knowledge systems reflected the idea that the boundaries between knowledge groups were not closed and that there could be considerable overlap between knowledge systems. The constructions of agricultural knowledge systems thus included social interactions, communication, and the diverse processes individuals employ to create, use, and evaluate multiple types and sources of information. As such, there were six priorities to development agricultural extension system; the linkage between agricultural colleges, Rural Development Administration(RDA), branch of RDA, establishing the research institution of research and extension linkage. exchange research agent with extension agent, developing information technology system, bottom-up approach, the linkage between national project and regional within extension projects, enforcement of informal learning.

Although an academic journal has had an important role in the diffusion of knowledge and the confirmation of knowledge advancement, it has revealed several difficulties : long processing time for publishing, uni - directional communication, closed review process etc. But an electronic journal (E-Journal) can solve these problems and add several new advantages such as the multimedia expression of documents, and pre and post publication review. Moreover, it should be noted that an E-Journal is not an alternative medium which simply replaces an existing journal, but a new paradigm for scholarly communication. Although this paper reviews several issues related to E-Journal, the introduction of the concept of universal service and informal document style for flexible communication are noticeable. For effective diffusion of E-Journal, information infrastructures such as high - speed telecommunication networks and digital libraries are urgently needed. Government subsidy as in Great Britain is necessary for E-Journal publishing.

교차언어 검색 과정에서는 질의나 문서의 언어를 일치시키기 위한 변환 과정이 필수적이며, 이런 변환 과정에서 어휘의 중의성으로 인해 하나의 어휘에 대응하는 다수의 대역어가 생성됨으로써 사용자의 정보 욕구를 왜곡시켜 검색의 성능을 저하시킬 수 있다. 본 논문에서는 어휘 중의성 문제를 해결하기 위해서 질의의 문맥 정보를 이용하여 변환 질의의 확률을 구함으로써 중의성을 해소하는 방식을 제시하고, 질의의 길이, 중의도, 중의성을 가진 어휘의 비율 등에 따라서 성능이 어떻게 변하는지 비교함으로써 이 방법의 장점과 단점을 분석한다. 또한 현재의 단점을 보완하기 위한 차후 연구 방향을 제시한다.
