능력기반 질의 처리기는 데이터 소스의 질의 처리 능력과 데이터 소스에 대한 목적 질의 (target query)를 입력으로 받아 목적 질의와 동일한 결과를 내는 질의 수행 계획을 출력하는 시스템이다. 이전 능력기반 질의 처리기에서는 AND 결합 질의(Conjunctive query)만을 처리하였기 때문에 데이터 소스의 질의 처리 능력을 충분히 이용하지 못했다. 본 논문에서는 AND 및 OR연결 (Disjunctive query) 형태의 목적 질의에 대한 질의 재작성 방법을 제시한다. 재 장성된 질의는 데이터 소스에서 처리 가능한 지원 질의(supported query)들의 유니온으로 표현된다. 제안된 시스템에서는 각 지원 질의의 질의 수행 계획에 대한 기여도와 수행 비용을 고려함으로써 질의 재작성에 필요한 탐색 공간을 줄이고, 최적화 된 질의 수행 계획을 생성할 수 있다.

Several problems occur in reading education in a elementary school. They are the lack of considering the difference of student's capability and diagnosing their reading ability, the review activity focusing on only text and the discontinuation between school and home. Our system is designed and implemented to support leveled reading education using multimedia technology. We can diagnose the student's reading ability exactly and promptly and introduce suitable books considering their ability, and work the proper review activities with this system. It can help the students to interest their reading.

Mentally disable children feel as failure because they have difficulty in restricted and undifferentiated communications with others. It also makes the counter-partner feel frustrated. Therefore, in the aspects of language acquirement and communication activities, it is essential to let the disable children learn and communicate voluntarily. Music provides the unthreatening and interesting stimulus as non-language communication vehicle. Musical experiences for mentally disable children's are multi-stimulating experiences that make a positive influence in speech and language development and development of variety of talents. There are many communication intervention and method to treat the mentally disable children. One of the most effective treatments for mentally disable children to acquire communication techniques by expressing the language more naturally and joyfully is the musical therapy. This study analyzes children's communication technique referring to response action and attempt action through video tape observation. Also, this study measured the receptive and expressive language by PRES(Preschool Receptive-Expressive Language Scale) as a test tool in order to examine the pre-post language ability for respective children as pre-post period of therapy activity. First result of this study showed that music therapy with song was effective for mentally disable children in enhancing the communication techniques centered with communication response and in attempt action by increasing the communication action incidence. Secondly, pre-post comparison test with PRES showed that the music therapy with song was effective on improvement the receptive and expressive language ability of 4 children.

This study on strategy and its function in debate offer the materials of education concrete and practical to be able to improve the expression ability and comprehension ability of the students, and can give lots of help to improve the ability of application that can answer quickly in trouble circumstances. The type of strategy in the course of set up the theory are (1) the form of concept definition, (2) the form of solution offer, (3) inductive form and deductive form, (4) the form of example offer. The type of strategy in the course of contradict are (1) the form of soliloquy, (2) the form of claim comparison, (3) the form of partial recognition. The type of strategy in the course of cross examination are (1) the form of question in return and contradict, (2) the form of partial consent contradict. We believe this study will improve the communication ability and negotiation ability and also make a great contribution to improve the leadership of 21-century type if this study will be used in the field of education.

This study investigated how elementary students with different spatial ability constructed spatial thinking process about on volcanoes and earthquakes with GeoMapApp-based materials. Students' spatial thinking process was analyzed in terms of spatial concept recognized, tools of spatial representation, and their spatial reasoning to construct topographic structure. The student group with high-scored spatial ability showed the spatial reasoning based on internal representation of building mental images through sectional division of horizontal distance, directly connected with spatial concept, or distorting spatial concept. The student group with low-scored spatial ability built the spatial reasoning directly connected with spatial concept instead of transforming into internal representation, and partially recognized spatial concept on either distance or depth. Based on the results, we argued identifying spatial concepts such as distance, height, or depth from the GeoMapApp data would be funda- mental for the better spatial thinking.

This study was conducted to compare the phenotypic performance and genetic merits in terms of weight at 12 months, carcass weight, eye muscle area, backfat thickness, marbling score and selection index of Hanwoo young bulls and proven bulls from the year 2004 to 2006. The data of 208 bulls used in this study were taken from the Nnational Hanwoo genetic evaluation coordinated by National Institute of Animal Science. Hanwoo young bulls were superior in the phenotypic performance of weight at 12 months, carcass weight, and eye muscle area showing significant differences from Hanwoo proven bulls in most comparisons. The backfat thickness of Hanwoo young bulls was significantly thicker higher than Hanwoo proven bulls in all comparisons (p < 0.05). Also, Hanwoo young bulls were not significantly different from Hanwoo proven bulls in the genetic merits of weight at 12 months, carcass weight, eye muscle area, backfat thickness, marbling score, and total genetic merits. Performance of Hanwoo young bulls were not significantly different from 1st class of Hanwoo proven bulls in all the traits studied except in eye muscle area.

본 연구에서는 종합병원에 근무하는 간호사를 대상으로 감정노동과 감성지능이 직무스트레스에 어떠한 영향을 미치는지 알아보고자 한다. 본 연구에서 간호사들의 감정노동과 감성지능 변인들의 직무스트레스에 대한 분산 설명력은 31.9%였고, 회귀모형은 유의미한 것으로 나타났다(F=7.615, p<.001). 분석결과, 감정노동 변인 중 감정표현의 빈도는 직무스트레스에 유의미한 부(-)적 영향(${\beta}=.206$ p<.05)을, 감정표현 규범의 주의성은 유의미한 정(+)적 영향(${\beta}=.318$, p<.01)을 미치는 것으로 나타났으며, 감성지능변인 중 자기감정이해(${\beta}=.195$, p<.05)와 감정조절(${\beta}$=-.192, p<.05) 변인이 직무스트레스에 유의미한 부(-)적 영향을 미치는 것으로 나타났다. 이들 변인들의 상대적 영향력은 표준화계수(${\beta}$)를 통해 알 수 있듯이, 감정표현 규범의 주의성, 감정표현의 빈도, 자기감정이해, 감성조절 등의 변인 순으로 직무스트레스에 미치는 영향력이 큰 것으로 분석되었다. 이와 같은 결과를 통해, 간호사들이 직무스트레스를 낮추기 위해서는 환자들과 긍정적인 감정표현을 많이 하고, 간호사들이 병원의 감정표현 규범으로 인해 표현하지 못한 감정을 해소할 수 있는 방안이 필요하며, 자신의 감정에 대한 이해와 감성조절 능력을 기르도록 스스로 노력이 필요함을 알 수 있었다.

The art appreciation education is emphasized to develope independent thought and upright value decision in the flood of various image medium. A experience of beauty and a express part related with the sentimental field is focused on directing in the seventh arts curriculum, too. Although the art appreciation education is emphasized, just expressive and functional art texture is still taught in the education spot up to now. Also a appreciative activity is limited simply to describe own feeling intuitionally ; time shortage, difficulty of analysis product, difficulty of guiding appreciation. In this paper I refer that analyze figurative factors of a art product, modify it by applying other program, compare with it and then I develope web base art appreciation system and apply it. As a result I get educational effect. When checking line, form, light and darkness, color, feeling, space and composition of external some factors in a product, formative sense and analytical appreciation is improved.

상황은 실세계에 존재하는 실체의 상태를 특징화하여 요약한 정보로 정의될 수 있으며, 상황인식은 이러한 상황 정보의 상호 작용에 의하여 인간의 현재 상황을 특성화 할 수 있는 기술적 방법을 의미한다. 실세계의 상태를 표현하는 것은 정보의 표현 및 지식 표현과 관련되며, 상황인식 컴퓨팅은 이러한 지식 표현 방법에서 출발한다고 할 수 있다. 본 논문에서는 앞서 말한 상황인식 능력을 지향하는 시스템, 즉 지능형 홈 서비스를 제공하는 상황인식 컴퓨팅 시스템을 제안한다. 본 논문에서는 가정 내에 설치된 센서장치로부터 사용자 생체 신호 데이터와 환경 데이터를 획득하한 후에, 획득된 컨텍스트 데이터를 정규화하고, 정규화된 컨텍스트 데이터를 패턴인식 알고리즘을 통하여 처리한 후에 자동적으로 지능형 홈오토메이션 서비스를 제공하는 게이트웨이에 대한 설계에 대하여 서술한다.

XML은 강력한 데이터 표현능력을 인정받아 전자상거래와 같은 데이터 처리 분야에 적극적으로 도입되고 있다. 하지만 XML을 이용하여 다른 조직이나 사용자간에 원활한 데이터 교환과 사용을 위해서는 공통적으로 사용할 수 있는 태그나 용어가 표준화되어야 한다. 현재 이와 같은 표준화 작업은 CommerceNet에서 주관하는 xCbl이 주를 이루고 있으며, RosettaNet과 BizTalk에서도 자신의 고유한 문서 표준을 채택하고 있다. 하지만 위의 표준은 B2B간의 상품이나 서비스에 대한 포괄적인 관점으로 기술되었기 때문에 상품 자체의 세부적인 정보 표현에는 부족한 점이 있다. 또한 현재 국내에서 이와 같은 표준에 대한 구축이 초기 단계에 있기 때문에 산업별, 산업간 정보 연계를 위한 표준화가 시급하다. 본 논문에서는 이와 같은 표준화 작업의 일환으로 XML에 기반 하여 가능한 모든 상품을 기술할 수 있는 표준 모델을 제시하고 이를 XML의 DTD로 구현하였다.
