In this study, we investigated the biological activity of antioxidant and antibacterial activity of Indigenous Plants, Jeju-Island., which, using methanol were extracted. The reducing activity on the 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical and $O^{2-}$ and OH radical scavenging potential, in search for antioxidation activities of Indigenous Plants, were sequentially screened. Among the ten plant parts, Prunella vulgaris var. aleutica Fernald. flower had the highest antioxidative activity. 80% Methanol extracts of ten indigenous plants were screened for antibacterial activity 13 fish pathogenic bacteria by agar diffusion method. Among the various 80% Methanol extracts, the Prunella vulgaris var. aleutica Fernald, Gleichenia japonica Spreng, Microlepia marginata (panzer) Christ., Perilla frutescens var. japonica Hara. showed relatively strong antibacterial activities in the order.

In this study, we link informal Web resources to KISTI NDSL's collections using automatic semantic indexing and tagging to examine the possibility of the service which recommends related documents using the similarity between KISTI's formal information resources and informal web resources. We collect and index Web resources and make automatic semantic linking through STEAK with KISTI's collections for NDSL retrieval. The macro precision which shows retrieval precision per a subject category is 62.6% and the micro precision which shows retrieval precision per a query is 66.9%. The experts' evaluation score is 76.7. This study shows the possibility of semantic linking NDSL retrieval results with Web information resources and expanding information services' coverage to informal information resources.

This study analyzed NCS-enabled Web services at colleges. The search scope was based on the NCS Support Center, etc. of the two domestic and one overseas portal sites. Support for the NCS Support Center web service from 12 Junior Colleges was analyzed after the search. There were three categories of NCS-enabled Web services. First, NCS-enabled service status analysis, second, NCS-enabled project status analysis, and third, junior college-specific differentiated NCS-enabled web service analysis were conducted. As a result, NCS-enabled services had more quantitative web pages than NCS-enabled project status services. However, NCS-enabled project status services have been presented with more detailed and practical data than NCS-enabled services. Differentiated Web services were able to analyze what included efforts to maximize NCS Web service support for each Junior College. Based on the results of this study, we look forward to improving the quality of NCS-enabled web services for Junior College education.

Objective: The purpose of this study was to investigate the effects of telerehabilitation on stroke patients through remotely operated intervention and monitoring. Methods: Literature from 2000 to April 2018 was collected through PubMed, Embase, Cochrane, and RISS. We used telerehabilitation, telemedicine, and stroke as the search terms in regard to foreign literature, and the terms telerehabilitation, stroke, and CVA in regard to Korean literature. A total of 406 foreign and 15 Korean published studies were found. As a result, a total of seven documents was selected for the analysis. Results: As a result of the analysis, all the interventions applied through telerehabilitation were provided remotely, and significant effects were reported between pre-post assessments. In addition, the significant effects of telerehabilitation were reported through analyzing pre-post(n=7) and between groups(n=4) assessments. The monitoring used could be categorized according to purpose, that is, for checking (n=3) and as an intervention (n=4). Conclusions: This study confirmed, within limits, that the application of telerehabilitation could be a potential alternative for stroke patients with limited rehabilitation services. In order to apply telerehabilitation in Korea, it is necessary to study the cost effectiveness, according to the current domestic situation, and confirm the most effective monitoring method based on the intervention.

본 연구는, 기존의 나열식 분류체계의 문제점을 극복할 수 있는 GRAIL을 이용하여 두경부의 해부학적 구조물들 및 구강 악안면 영역의 주요 질병들과 관련된 치의학 개념들의 모델을 구축한 뒤, 완성된 치의학 개념 모델이 두경부의 해부학적 구조물들 및 구강 악안면 영역의 주요 질병들을 잘 표현할 수 있는지와 기존의 GRAIL 모델이 지닌 특징에 잘 부합하는지를 평가하고자 시행되었다. 서울대학교 치과병원 내원 환자 중 포괄적인 치과 치료 병력을 지닌 환자 150명의 치과 의무기록을 내용별로 분석하고, 각종 치의학 교과서와 기존의 의학용어 분류체계에서도 모델 구축에 필요한 치의학 용어를 선택하였다. 이들 자료를 바탕으로, GRAIL 모델 구축을 진행하고 구축된 모델을 평가할 수 있는 소프트웨어 프로그램인 'KnoME'에서 치의학 개념 모델을 구축하고 평가하여, 다음과 같은 결론을 얻었다. 1. 환자 150명의 치과 의무기록을 내용별로 분석한 결과, 우선적으로 모델 구축이 필요한 치의학 용어로는, 해부학적 구조물의 경우 치아, 치은, 악관절, 입술, 턱, 혀 등의 순서로 나타났으며, 구강악안면 영역의 병소에서는 치아 우식증, 치주염, 치은염, 악관절 장애, 매복 지치, 치경부 마모 등의 순서로 나타났다. 2. GRAIL을 이용하여 치아, 치주조직, 구강점막조직, 치아 우식증, 치수 및 치근단 병소, 치주질환, 구강점막질환의 모델 구축을 시행한 결과, 치의학 개념간의 다양한 관계가 대다수 잘 표현되었다. 그러나, 구강 악안면 영역의 해부학적 구조물에 대한 공간 정의의 한계성과 구강 악안면 질환의 진행 양상에 있어서 표현의 어려움이 관찰되었다. 이러한 부분은 GRAIL을 치의학 분야에 적용할 때, 극복해야 할 한계로 나타났다. 3. 치의학 개념들에 관한 다양한 질의를 시행한 후 그 응답 내용을 평가한 결과, 완성된 모델 내에서 치의학 개념의 자동적인 분류가 이루어 졌으며, 다양한 목적의 검색이 가능하였다. 이와 같은 사실로 미루어 보아서, 완성된 모델은 기존의 GRAIL 모델의 특성에 잘 부합되는 것으로 생각되었다.

The purpose of this study is to analyze the research published in Korea on the live atrium of Toegye Lee Hwang and present its applicability as a health dance program.To this end, Korean academic journals, the Korean Institute of Information Scientists and Engineers, and DBpia searched Korean journal publications with the keyword 'active visit', and 24 articles published from 1974 to December 2018 were classified into the Korean Research Foundation.According to the criteria, they were classified and analyzed into subclasses. As a result, first, the research trends of academic disciplines by year tended to increase the participation of various academic disciplines in the atrium.The interests of the live atrium differed in the order of physical education.Second, in terms of research subjects, more researches attempted to identify active atria as a research topic than research suggesting a plan.Third, the trends of the research topics were in order to study academic definition of live atrium, to find out the relationship between live atrium and other disciplines, to propose ways to use them, and to develop programs.Fourth, by applying the live atrium to a dance program, we found the potential as a dance program for health promotion.It is expected that these findings will not only provide the basic data for the possibility of a health dance program integrated with various fields, but also contribute to the search for the direction of health dance program research.

Lookup Is one of important factors for network traffic on peer-to-peer network. Especially, large amount of network resources are required for lookup process in p2p file sharing system that clients use the dynamic If and they import to p2p network in random. In this paper, we employ efficient lookup mechanism which searches lookup with the combined information of ISP key values and the extracted key values from SHA-1 hashing function for shared contents id. The proposed mechanism efficiently searches files on the network because the mechanism processes P2P lookup with consideration the routing information of ISP. We suggest the adapted simulation environment based upon the famous file sharing system of emule P2P and experiment the proposed system.

다양한 플랫폼 상에서 응용 시스템에 대한 개발, 배포, 운영의 고생산성과 고품질을 얻기 위해서는 소프트웨어 구성 요소들의 체계적인 재사용 접근과 자동화된 도구의 지원이 요구된다. 함수나 클래스 라이브러리에서 설계 패턴과 프레임워크, 그리고 최근의 상업적인 비즈니스 컴포넌트에 이르기까지 여러 재사용 방법이 제시되었으나 기대만큼의 확실한 효과를 얻을 수 없었다. 설계 패턴은 설계 경험에 대한 캡슐화된 빌딩 블록으로 개발 응용의 표준화된 아키텍쳐 제공을 통해 응용 도메인의 한정성과 클래스 수준의 재상용의 복잡성을 극복할 수 있다. 응용 개발의 표준 아키텍쳐로서의 웹을 통한 재사용 요소들의 공유는 여러 개발자들에 의한 다양한 도메인 요소로서의 전개와 동적이며 실시간적인 라이브러리 관리가 가능하다. 본 논문에서는 웹 환경 하에서 자동화된 설계 패턴 재사용 환경 구축을 목적으로 한다. 그러므로 For Reuse 관점에서 서버 상에 각 도메인별 패턴 라이브러리를 구축하며 With Reuse 관점에서 패턴 검색, 이해, 획들 그리고 재구조화를 통한 응용으로의 재사용 지원기를 구축한다. 본 시스템은 패턴의 공유에 의한 유사 도메인 응용의 표준화를 유도하고 사용자의 패턴 재정의에 의한 자생적을 확장 가능한 패턴 라이브러리 제공이 가능하다. 또한 이를 위해 도메인 분석을 통한 패턴의 행위와 의도를 기준으로 설계 패턴들을 분류, 카탈로깅하여 재사용 라이브러리를 제시한다.

The recent growth of a digital music market induces increasing demands for music searching and recommendation services. In order to improve the performance of music-based application services, the process of extracting melodies from polyphonic music is essential. In this paper, we propose a method to extract melodies from piano solo music which is highly polyphonic and has a wide pitch range. We categorize piano music into three classes taking into account the characteristics of music, and extract melodies according to each class. The performance evaluation for the implemented system showed that our method works successfully on a variety of piano solo music.
