This paper proposes an effective indexing method about image databased models by the sorted color histogram. We can retrieve a lot of similar objects by experiments. For retriving the similar images, we used a technique called the histogram and the two level color histogram, which matches query images and reference images. Experimental results of image retrieval shows Precision:0.83, Recall:0.88. The above results have proved higher retrieval effects than the color histograms.

본 논문은 하둡 기반의 분산병렬처리에 의한 문서의 의미특징을 추출하고, 추출된 의미특징을 이용하여 문서를 요약하는 새로운 방법을 제안한다. 제안된 방법은 문서요약에 비음수 분해된 문서의 의미특징을 이용함으로써 문서의 내부 구조를 잘 표현 할 수 있다. 또한 하둡을 이용하여 빅데이터의 문서를 요약할 수 있다. 실험결과 제안방법이 단일 컴퓨터 환경에서 처리할 수 없는 대용량의 문서를 요약할 수 있음을 보인다. In this paper, we proposes a new document summarization method using the extracted semantic feature which the semantic feature is extracted by distributed parallel processing based Hadoop. The proposed method can well represent the inherent structure of documents using the semantic feature by the non-negative matrix factorization (NMF). In addition, it can summarize the big data document using Hadoop. The experimental results demonstrate that the proposed method can summarize the big data document which a single computer can not summarize those.

The purpose of this study was to find the exchange of blood exponents when the following five people, who were trained with aerobic at the age of twenty, ate uncooked food. First time. they had a meal with uncooked food twice a day and had other meal with cooked food. Second, we had 8weeks experiment period after exercise with the condition of exercise was 70% of maximum Heart Rate and then extracted blood from venous blood according to the following condition. after 4weeks and 8weeks one hour before and after exercise. Third. we observed the exchange of following items, Total Prototein, Albumin. Hemoglobin Triglyceride, Total cholesterol, Glucose, Heart Rate, Blood Pressure, Weight. The results of this study are as follow 1) Blood Pressure After systolic blood pressure exercise, It was 4.9% decreased in both case of 4weeks and 8weeks after 2) Heart Rate During exercise: 4.5% decreased after 4weeks. 4.3% decreased after 8weeks After exercise: 4.5% decreased after 4weeks, 8% decreased after 8weeks 3) Triglycegide Before exercise: 12.3% increased after 4weeks,13% increased after 8weeks After exercise: 7.6% decreased after 4weeks. 11% increased after 8weeks 4) Cholesterol During exercise: 7.1% decreased after 4weeks. 14% decreased after 8weeks After exercise : 4.5% decreased after 4weeks. 11.3% decreased after 8weeks 5) There was no difference in the Weight, Total protein. Albumin. Hemoglobin, Glucose

본 논문에서는 하이퍼미디어 브라우징을 위하여 노드들 사이의 연결 관계를 구성하는 링크 도구와 내용흐름을 제어하는 브라우징 도구 등을 제공하며, 동적인 하이터미디어 브라우징을 지원한다. 링크 도구는 노드사이의 연결관계를 구성하고자 할 때 이용된다. 링크는 내부링크와 외부링크로 구분되며 시간정보를 가질 수 있다. 브라우징 도구는 사용자 모드에서 노드를 실행시키거나 노드 이동을 자유롭게 할 수 있고, 여러 노드들에 대한 연관 관계를 제공할 수 있다. 일반적으로, PC환경에서는 MHEG에서 제안한 동기화 방법 표현이 가능하도록 하였다. 여러방식의 브라우징을 지원하여 사용자가 필요한 정보를 검색하는 방식을 지졍할 수 있게 하였다. 히스토리, 역추적, local map과 global map등의 브라우징 기능을 두어 하이퍼미디어의 문제점을 감소시켰다. 그래픽 사용자 인터페이스를 두었고 범용성을 위하여 일반 PC상에서 구현하였다. This paper provides the link tools constructing link relation among nodews for hypermedia browsing and the browsing tools controlling the content flows, and provides dynamic hypermedia presentations. The link tools are used for construction of the link relation among nodes. The links have internal links and external links, and have the time information. The browing tools can provide the related information about nodes, move or play nodes in user mode. In general, PC environment is able to present the synchronization method proposed in MHEG(Multimedia and Hypermedia information coding Expert Group). User can define the browing type by using the link type to select the desired presentation type of information. The proposed browsing functions to reduce the problem of hypermedia are histroy, back tracking, local map and global map with scrolling. These functions are developed on the general purpose PC and used the user friendly graphical user interface(GUI).
