계통발생학적 분석은 바이오인포메틱스에서 분류 단위의 진화적인 관계를 추정하는데 있어서 중요한 문제 중 하나이다. 계통발생학적 분석에서 사용되는 계통수는 분류 단위들 사이의 진화 거리에 대한 정보를 표현하기에는 부족하다. 이 논문은 진화거리 표현을 위해 3차윈 공간으로 분류 단위가 표현되기 위한 방법을 제안하고, 2차원 트리 뷰와 함께 3차원 공간에서 분류 단위들을 시각화하기 위한 도구를 개발하였다.

무선 센서들의 진보에 따라 환자의 상태를 모니터링 하거나 정보를 저장 후 원거리에 있는 의사들의 진단 제공이 가능하게 되었다. 하지만 환자의 데이터의 양에 비해 의사의 수가 적으므로 환자가 진단을 제공 받는데 시간적인 한계가 있다. 따라서 본 연구에서는 환자의 상태를 1 차적으로 자동 진단하는 시스템을 제안한다. 전체 데이터의 적용을 위해 Circadian rhythm에 기반한 데이터 직접방법을 제안하고 데이터를 효율적으로 분류하기 위해 PSO(Particle Swarm Optimization)을 기반으로 하는 분류화 알고리즘을 적용하여 시스템의 수행속도 향상을 도모하였다.

With the development of the internet and international agreements such as the Convention on Biological Diversity (CBD) and the Convention on International Trade in Endangered Species (CITES), Korean researchers frequently encounter scientific names of foreign species, and these are named on a case-by-case basis in Korean without any standard naming method. Therefore, standard Korean names for entire orders and families in the world are required for better communications in Korea. However, there have been no comprehensive discussions of the standardization of Korean names for the orders and families found in the world. In this study, we 1) compare the Korean names of orders and families in the references, 2) discuss naming methods in Korean for foreign taxa, and 3) then suggest standard Korean names for the orders and families in the APG III, which is an up-to-date angiosperm classification system. This study will be a starting point for the national standardization of Korean names for orders and families found throughout the world.

As the digital technology has improved, the numbers of Hangul font users have increased and their individual needs and taste are diversified. Therefore new and various Hangul fonts out of traditional form are developed and used. But under the present font classification system, it is hard to compare and analyze these various fonts. And the present classification system is hard to be the font user's guide for proper use of various Hangul fonts. For the better use of Hangul font, to diversify the font classification system is needed. So we propose the development of these thru classification standards. First, structural classification based on the structural character of Hangul. Second, image classification based on the visual images of each font. And third, usage classification based on the fonts proper usage in various media. For the development of various typographically balanced fonts and for the suitable and effective use of the various font, we must try to build the font classification system based on the diversified classification standards and build Hangul font database based on this classification system. Through these studies, we can expect the development of good quality fonts and the better use of these fonts.

This study was to suggest the improvement and the application of KDC 6 for classifying children's books by the literature review and survey. First, it was suggested to shorten the classification numbers by the divisions and subdivisions and to expand the classification numbers by sub-subdivisions according to the library-specific classification policy, using the subject statistics of the children's books held by 20 public libraries affiliated in Seoul Metropolitan Office of Education and representative C libraries. Second, the knowledge picture books and the fairy tales were suggested to be classified according to its subject, and the fairy tales in each country were suggested to be classified by adding sub-subdivisions and genre subdivisions. Third, it was suggested to shelve by collection and location codes that were distinguished by the ages and the reading level for user, to prepare a standard guideline for shelving, and to implement the regular user education about the classification system. This study could contribute to the development of the KDC abridged version for children's books in the future.

Recently, the scale and technical complexity of agricultural production has been growing. Therefore, agricultural facilities are being gradually diversified, expanded, and made more complex. To furnish Korea's agricultural industry with international competitiveness, it is thus necessary to introduce new management techniques. The PCM (procurement-construction-maintenance) information management system for agricultural facilities is established by setting up its WBS (work breakdown structure). In this study, the WBS of a facility such as facility, space, element, works, and resources is analyzed. Following this analysts, a WBS of an agricultural facility that is appropriate for the PCM information system of an agricultural facility, is proposed by deriving it from actual WBS.

본 논문에서는 개념을 기반으로 문서의 분류를 하는 확률벡터 모델의 분류기TAXON(Concept-based Text Categorization System)의 개선을 도모한다. TAXON은 한국어 문장을 분석하여 명사를 추출하고 명사의 개념을 시소러스 도구를 통해 획득한 후 이를 벡터화하여 주제와 입력 문서와의 관계성을 검사하는 문서 분류기이다. 본 논문은 문서 분류기 TAXON의 성능을 향상시키기 위하여 확률벡터 계산에 가중치 부여 휴리스틱을 도입한다. 그리고 시소러스 도구를 확장하여 문서 분류의 질을 높인다.

To structure the KOS registry, it is necessary to select a classification system that suits the characteristics of the collected KOS. This study aimed to classify domestic KOS collected through various classification schems, and based on these results, provide insights for selecting a classification system when structuring the KOS registry. A total of 313 KOS data collected via web searches were categorized using five types of classification systems and a thesaurus, and the results were analyzed. The analysis indicated that for international linkage of the KOS registry, foreign classification systems should be applied, and for optimization with domestic knowledge resources or to cater to domestic researchers, domestic classification systems need to be applied. Additionally, depending on the field-specific characteristics of the KOS, research area KOS should apply classification systems based on academic disciplines, while public sector KOS should consider classification systems based on government functions. Lastly, it is necessary to strengthen the linkage between domestic and international KOS, which also requires the application of multiple classification systems.

본 논문에서는 최근 활발히 연구가 진행되고 있는 행위인식 연구 분야 중에서 스마트폰 환경에서의 개인화된 행위 인식기 및 로거를 제안한다. 최근 스마트폰의 보급이 활발해지면서 행위 인식 연구 분야에서 스마트폰을 이용하는 연구가 활발히 진행되고 있다. 그러나 스마트폰에서는 센서를 이용하여 행위정보를 수집하고, 서버에서 는 분류 및 처리하는 방식으로 실시간 인식과 개발자에 의한 트레이닝으로 인해 개인화된 트레이닝이 불가능하다는 단점이 있다. 이러한 단점을 극복하고자 Naive Bayes Classifier를 사용하여 스마트폰 환경에서 실시간으로 사용자 행위 수집이 가능하고 행위정보의 분류 및 처리가 가능한 경량화 및 개인화된 행위 인식기 및 로거의 구현을 목적으로 한다. 제안하는 방법은 행위 인식기를 통해 행위 인식이 가능할 뿐만 아니라 로거를 통해 사용자의 라이프로그, 라이프패턴 등의 연구 분야에 이용이 가능하다.
