We propose a hybrid pattern recognition method that effectively combines two different features for improving data classification. We first extract the PCA (Principal Component Analysis) and LDA (Linear Discriminant Analysis) features, both of which are widely used in pattern recognition, to construct a set of basic features, and then evaluate the separability of each basic feature. According to the results of evaluation, we select only the basic features that contain a large amount of discriminative information for construction of the combined features. The experimental results for the various data sets in the UCI machine learning repository show that using the proposed combined features give better recognition rates than when solely using the PCA or LDA features.

The traditional oriental materials are very important to study on Oriental or Korean studies. Every reseacher that study on this field is familier to Four Category Classification Scheme (四部分類法) as it is based on the traditional knowledge of Orient. Then, when all materials of libraries will he computerized, it will be the first condition that will has to understand about the classification of division and section of oriental knowledge, because not only ancient literature but also many dissertation of this subject will be classified. Therefore, Four Category Classification Scheme has been valuable until now. This paper is intended to help librarians to classify the traditional oriental materials or the dissertation concerned with that, to serve researched user that literatures which have been filed among various traditional bibliographies. The outline of this study are as follows: :1 Examining closely origins, developing process and characteristics of classification of Confacian Classics Part (經部) of Four Category Classification Scheme. (2) Explaning the content of division and section of Confucian Classics Part (經部). (3) Coordinating relation of division and section of Confucian Classics Part as well as those of other parts of the classification scheme. (4) Clearing up the limitation of classification related to other division. (5) Attempting to give basic knowledge on practical classification as concrete examples beloging to each division and section of classification.

Four Category Classification Scheme(四部分類法), the traditional classification, is the most proper for classifying the traditional oriental marerials than some other classifications. Therefore, Four Category Classification Scheme has been valuable until now. It is obvious that this classificion aims at a rapid and accurate reference in sorting out the materials and maximun use. This paper is intended as a sludy which helps librarians to classify traditional oriental materials. It is also intended to serve librarians to have easy access to ancient literatures which have been filed among various traditional bibliographies for those who are to research oriental materials as an analysis about Miscelleneous Part(子部). The outline of this study are as follows : (1) Examining closely origins, developing process and characteristics of classification of Miscelleneous Part of Four Category Classification Scheme. (2) Explaining the content of division and section of Miscelleneous Part (子部). (3) Coordinating relations of division and section of Miscelleneous Part as well as those of other parts of the classification scheme. (4) Clearing up the limitation of classification related to other division. (5) Attempting to give basic knowledge on practical classification as concrete examples belonging to each division and section of classification.

The purpose of this paper is to give the classification of homogeneous integral table algebras of degree 5 containing a faithful real element of which 2. In fact, these algebras are classified to exact isomorphism, that is the sets of structure constants which arise from the given basis are completely determined. This is work towards classifying homogeneous integral table algebras of degree 5. AMS Mathematics Subject Classification : 20C05, 20C99.

We create a malware detector classification method with using the Sequential Probability Ratio Test (SPRT) in IoT. More specifically, we adapt the SPRT to classify malware detectors into two categories of basic and advanced in line with malware detection capability. We perform evaluation of our scheme through simulation. Our simulation results show that the number of advanced detectors is changed in line with threshold for fraction of advanced malware information, which is used to judge advanced detectors in the SPRT.

In order to improve the integrating accuracy and to elevate the serviceability of the KM(Korean Medicine) ontology constructed by the Korea Institute of Oriental Medicine, this research simplified the many-to-many corresponding relationship between groups of methods of treatment and groups of accompanied symptoms from disease ontology and categorized systematically the relationship. We first extracted the combinations of methods of treatment and accompanied symptoms from the KM ontology, then categorized the attributes of combinations that their frequencies were over 10 times by analyzing KM terms definition and the basic KM theory. We constructed the classification hierarchy having 14 kinds of classification in 4 steps and extracted 450 meaningful combinations. This research improved the integrating accuracy and elevated the serviceability of KM information by the classification system.

수학적인 사고에는 여러가지 유형이 있는데 그 중에서 가장 기본이 되는 사고유형이 분석과 종합이다. 이러한 사고유형을 담고 있는 분석과 종합문제는 수학문제의 가장 중요한 근간이라고 할 수 있다. 이러한 분석과 종합문제에 대한 체계적인 분석과 구체적인 논의를 위해 러시아의 구세프 교수가 편찬한 수학교과서를 중심으로 이러한 두 가지 유형의 문제에 대한 분석을 실시한다. 또한, 역사적으로 제시되어진 분석과 종합에 대한 다양한 문헌연구를 통해 두 가지 사고유형의 분류에 대한 기본적인 기준을 설정하고, 이를 바탕으로 분석문제와 종합문제에 대한 구체적인 분류기준을 제시하고자 한다.

Background: There is minimal literature on the morphology of partial distal biceps tendon (DBT) tears. We sought to investigate tear morphology by retrospectively reviewing 3-Tesla magnetic resonance imaging (3T MRI) scans of elbows with partial DBT tears and to propose a basic classification system. Methods: 3T MRI scans of elbows with partial DBT tears were retrospectively reviewed by two experienced observers. Basic demographic data were collected. Tear morphology was recorded including type, presence of retraction (>5 mm), and presence of discrete long-head and short-head tendons at the DBT insertion. Results: For analysis, 44 3T MRI scans of 44 elbows with partial DBT tears were included. There were 9 isolated long-head tears (20%), 13 isolated short-head tears (30%), 2 complete long-head tears with a partial short-head tear (5%), 5 complete short-head tears with a partial long-head tear (11%), and 15 peel-off tears (34%). Retraction was seen in 5 or 44 partial tears (11%), and 13 of the 44 DBTs were bifid tendons at the insertion (30%). Conclusions: Partial DBT tears can be classified into five sub-types: long-head isolated tears, short-head isolated tears, complete long-head tears with partial short-head involvement, complete short-head tears with partial long-head involvement, and peel-off tears. Classification of tears may have implications for operative and non-operative management. Level of evidence: III.

Disaster management system should be built for minimizing damage factor that affects to construction facility from natural disaster. It could be classified by three categories such as disaster prevention, damage survey and recovery phases. For an integrated disaster management system, a disaster information classification system(DICS) is necessary for the reasonable disaster information management. This study suggests an integrated DICS that includes disaster type classification, facility type classification and information type classification for disaster management service. The applicability of suggested DICS is verified by railway facility and the research result could be used as a basic information system for national disaster management system.

본 연구의 목적은 한식 관련 정보를 개념화하고 풍부하게 조직할 수 있는 패싯 구조를 개발하는 것이다. 이를 위해 한식 분야의 학문적인 흐름과 동향, 핵심적인 개념을 파악하여 한식 분야의 지적 구조를 분석하였고 한식 관련 국내서 776권의 목차 데이터와 인터넷 포털 사이트의 디렉터리에서 한식 관련 항목명, 총 23,470건을 수집 분석하였다. 수집된 용어를 범주화하여 공통 속성을 도출하고, 기본 패싯 및 하위 패싯을 정의하였으며, 패싯 간에 계층 구조, 기본 열거 순서와 기호화를 결정하였다. 한식에 관한 16개의 기본 패싯과 85개의 하위 패싯과 함께 패싯의 인용 순서를 '음식 종류'를 중심으로 재료, 에너지, 공간, 시간 순으로 조합하도록 제안하였다. 본 연구의 결과는 글로벌 한식 정보 조직과 검색의 효율화를 가져올 것이며, 패싯 분석을 통한 주제 분야별 분류체계 모형 개발의 기초가 될 것이다.
