조직의 데이터를 효과적으로 관리하는 대표적 방법은 기존 데이터의 공유와 재사용을 촉진하여 데이터의 중복 생산을 방지하는 것이다. 데이터 공유와 재사용의 촉진을 위해서 기존 데이터의 체계적 구조화와 효율적인 검색이 지원되어야 한다. 이러한 점이 고려되지 않은 조직간 단절된 데이터 개발은 데이터 중복을 양산하고 데이터의 품질을 저하시킨다. 데이터 분류는 관리하는 데이터에 대한 체계적 정리로 원하는 데이터 요소의 빠른 검색을 가능하게 한다. 본 논문에서는 데이터 공유, 재사용과 통합을 극대화하고 MDR과 시멘틱 웹에서 효과적으로 사용될 수 있는 본질기반 데이터 분류 방법론을 제안한다. 본질기반 데이터 분류 방법론은 데이터 본질을 기반으로 데이터 분류 구조를 구성하여 업무분류에 독립적인 데이터 분류가 가능하다. 또한 제시된 데이터 분류 구조를 지원하는 데이터 분류 절차를 제시하여 다양한 데이터 요소들을 데이터 분류 구조에 따라 배치하는 방법을 보인다. 사례연구에서는 제안된 데이터 분류 구조와 데이터 분류절차가 효과적으로 실제에 적용 될수 있음을 보였다.

In Soil Taxonomy system, anthropogenic soils are still classified as Entisols since the International Classification Committee for Anthropogenic Soils is in the process of classifying anthropogenic soils as new orders. In reality, it is difficult to characterize anthropogenic soils because Soil Taxonomy (ST) system does not distinguish between natural and anthropogenic Entisols. On the other hand, World Reference Base for soil resources (WRB) considers human impacts on soils and contains an independent category of anthropogenic soils, which makes easier to understand anthropogenic soil characteristics than Soil Taxonomy system. A remodeled paddy field (Gasan) was selected to classify by ST and WRB. Soil samples were taken to analyze chemical and physical properties. Based on the results of the analyses, the ST system classified Gasan as coarse loamy, mixed, mesic, Aquic Udorthents while the WRB did as Stagnic Urbic Technosols (Oxyaquic, Arenic). As a conclusion, the WRB classification information of the anthropogenic provides more detail characteristics of the anthropogenic soils.

More than 30 years have elapsed since the first report of the International Committee on Taxonomy of Viruses (ICTV) was published in 1971. Since that publication, the ICTV recognizes about 1,550 virus species, but some 30,000 virus strains and isolates are being tracked by virologists in different fields of biology. The ICTV is the 'international court' of experts that rules on names and relationships of all virus, but only to the level of species. Virus taxonomy is changing rapidly, with changes ranging from the trivial(use of italics for species names) to profound reorganization driven by the explosion of sequence information. The universal system of viral taxonomy now accepts Linnean-like classification at the levels of order, family, subfamily, genus, and species. The suffix '-virales' identifies an order, Families are identified by the suffix '-viridae' subfamilies are identified by the suffix '-virinae', and genera are identified by the suffix '-virus'. The importance of distinguishing subspecies, strains, and isolates in vaccine development, diagnostics, etc. is recognized, but these lower levels are not formally classified by ICTV. This paper mainly introduces taxonomy and classification of animal viruses on the basis of the seventh report of the ICTV edited by Van Regenmortal et al. in 2000.

Objective: The aim of this study is to suggest three-dimensional(3D) hand gesture taxonomy to organize the user's intention of his/her decisions on deriving a certain gesture systematically. Background: With advanced technologies of gesture recognition, various researchers have studied to focus on deriving intuitive gestures for commands from users. In most of the previous studies, the users' reasons for deriving a certain gesture for a command were only used as a reference to group various gestures. Method: A total of eleven studies which categorized gestures accompanied by speech were investigated. Also a case study with thirty participants was conducted to understand gesture-features which derived from the users specifically. Results: Through the literature review, a total of nine gesture-features were extracted. After conducting the case study, the nine gesture-features were narrowed down a total of seven gesture-features. Conclusion: Three-dimensional hand gesture taxonomy including a total of seven gesture-features was developed. Application: Three-dimensional hand gesture taxonomy might be used as a check list to understand the users' reasons.

질문 분류는 질의응답과정에서 질문자의 정보요구를 이해하고 주어진 질문에 대해 적합한 답변을 제공하기 위한 중요한 방법 중의 하나이다. 이 연구의 목적은 온라인 및 도서관에서 활용 가능한 질의응답 서비스의 질문 분류체계를 조사해보고, 각 질의응답서비스의 유형별로 어떠한 특징이 있는지 살펴보고자 하였다. 이를 위해, 도서관의 참고서비스 및 온라인 상의 소셜 레프런스, 자동 질의응답 시스템을 대상으로 질문을 어떻게 분류하여 활용하고 있는지를 문헌 조사를 통해 살펴보고 종합하여 질문의 유형을 정리하였다.

본 연구는 Saracevic과 Kantor(1997)가 개발한 도서관 서비스 가치의 분류체계를 적용하여 국내 도서관 이용자 16명을 대상으로, 이용자가 경험하고 표현하는 서비스 가치를 평가하였다. 이용자와의 직접적인 면담을 통해 이용자가 도서관서비스를 사용하게 된 동기 사용과정에서의 상호작용, 그리고 서비스의 이용을 통해 경험한 결과를 이미 개발된 분류체계의 구체적인 요소를 적용하였다. 이를 통해 다양한 목적으로 도서관 서비스가 사용되며 이용자 본인의 말로 표현된 서비스 가치를 포착, 분류할 수 있었다. 본 연구에서 사용된 면담 기법 등을 적절히 활용하면 이용자들로부터 서비스 가치와 관련된 구체적이고, 사실적인 언급을 수집할 수 있으며, 기존에 개발된 분류체계는 높은 포괄성과 적용성을 지닌 것으로 평가되었다.

The literature has recorded many models dealing with manpower forecasting and planning. The approaches used by the various authors are clearly disparate. This paper presents a taxonomy for manpower planning and forecasting methodologies and classifies the landmark developments in this field. The taxonomical schema is then applied to unify the models in consideration of the methods and the decision factors used for forecasting and/or planning. The taxonomy allows for the most complex model structure containing all the factors considered germane in the existing literature.

The goal of this study is to analyze accidents occurred at experimental laboratory and to suggest hierarchical taxonomy applicable to prepare countermeasures reducing the experimental laboratory accidents. Recent 5 years accidents were analyzed and classified according to their primary cause, facility or human. Then in case of facility, the accidents were further classified whether they can be fixed by organization or by individual. In case of human factor, they were classified into physical, chemical, or biological to prepare precise measures. Depending on the adequacy of appropriate practice, several measures were suggested such as; whether to improve training of laboratory workers, or to improve training the system, or to improve or prepare practice substantially. A new taxonomy for laboratory accident was suggested complying other governmental agencies' classification such as KOSHA and KGS. Additionally, two kinds of possibilities were suggested such as possibility of major accident and possibility of disaster which can be defined as laboratory accident causing large scale of harmful consequence to residential area or environment by fire, explosion and/or toxic release of hazardous chemicals and/or microbiology.

This study examines control types of IS outsourcing project management focusing on two sets of questions: What control types are implemented during IS outsourcing projects? How various control types affect the performance of IS outsourcing projects. In order to meet these objectives, four control types are developed using typology-approach: dynamic, contract-oriented, partnership-oriented, and passive. And then four control types are identified based on taxonomy-approach using cluster analysis from 66 projects: dynamic, contract-oriented, passive, and middle. The result shows that the derived taxonomy-types are similar to the typology-types except partnership-oriented type. The result also indicates that dynamic and contract-oriented types are in the highest performance, while passive type is in the least performance.

Recommender systems are a personalized information filtering technology to help customers find the products they would like to purchase. Collaborative filtering is known to be the most successful recommendation technology, but its widespread use has exposed some problems such as sparsity and scalability in the e-business environment. In this paper, we propose a recommendation system, WebCF-PT based on Web usage mining and product taxonomy to enhance the recommendation quality and the system performance of traditional CF-based recommender systems. Web usage mining populates the rating database by tracking customers' shopping behaviors on the Web, so leading to better quality recommendations. The product taxonomy is used to improve the performance of searching for nearest neighbors through dimensionality reduction of the rating database. A prototype recommendation system, WebCF-PT is developed and Internet shopping mall, EBIB(e-Business & Intelligence Business) is constructed to test the WebCF-PT system.
