Recently, new intelligent service frameworks, such as ubiquitous computing are proposed. So, the necessity of adaptive agent system has been increased. In this paper, we propose an intelligent service agent to help that ubiquitous computing system offer user suitable service in ubiquitous computing environment. In order to offer user suitable uT-service, an intelligent service agent mediates the gap between the context information in uT-service system, and user preference is reflected in it. Therefore, we focus on following three components; the first is suitable multi agent framework-agent communication analysis and applicable method of inference engine, the second is uT-ontologies to describe various context information-context information sharing between agents and context information understanding between agents, the third is learning method of user profile to apply in uT-service system. This approach enables us to build adaptive uT-service system to offer suitable service according to user preference.

최근 1인 미디어인 개인방송은 무선통신망과 스마트폰 등의 발달로 현재 많은 사람들이 이용하고 있는 인터넷 서비스 중 하나이다. 개인방송이 인기를 끌고 있는 가장 큰 이유는 방송을 진행하는 브로드캐스터와 시청자가 실시간으로 소통하며 양방향 서비스를 제공할 수 있기 때문이다. 하지만 기존의 플랫폼에서는 단순히 시청자들의 채팅을 통해서만 양방향 소통을 진행한다는 한계점이 존재한다. 이에 본 논문은 채팅로그뿐만 아니라 시청자들의 사진, 카메라 롤, 영상, 음성의 링크를 채팅창에 띄우고 부가정보서비스 창을 구축하여 다양한 의견을 공유할 수 있게 되고 브로드캐스터 컨트롤 시스템을 이용하여 부가정보서비스를 제어할 수 있게 됨으로써 한층 더 흥미로운 방송을 운용할 수 있게 하는 프레임워크를 연구하였다.

In this paper, we introduce a computing resource standard metadata schema design plan for registering, retrieving, and managing computing resources used for research data analysis and utilization in the Korea Research Data Commons(KRDC). KRDC is a joint utilization system of research data and computing resources to maximize the sharing and utilization of research data. Computing resources refer to all resources in the computing environment, such as analysis infrastructure and analysis software, necessary to analyze and utilize research data used in the entire research process. The standard metadata schema for KRDC computing resource management is designed by considering common attributes for computing resource management and other attributes according to each computing resource feature. The standard metadata schema for computing resource management consists of a computing resource metadata schema and a computing resource provider metadata schema. In addition, the metadata schema of computing resources and providers was designed as a service schema and a system schema group according to their characteristics. The standard metadata schema designed in this paper is used for computing resource registration, retrieval, management, and workflow services for computing resource providers and computing resource users through the KRDC web service, and is designed in a scalable form for various computing resource links.

In the collaborative product design environment, the communication between designers is important to capture design intents and to share a common view among the different but semantically similar terms. The Semantic Web supports integrated and uniform access to information sources and services as well as intelligent applications by the explicit representation of the semantics buried in ontology. Ontologies provide a source of shared and precisely defined terms that can be used to describe web resources and improve their accessibility to automated processes. Therefore, employing ontologies on assembly modeling makes assembly knowledge accurate and machine interpretable. In this paper, we propose a framework of semantic assembly modeling using ontologies to share design information. An assembly modeling ontology plays as a formal, explicit specification of a shared conceptualization of assembly design modeling. In this paper, implicit assembly constraints are explicitly represented using OWL (Web Ontology Language) and SWRL (Semantic Web Rule Language). The assembly ontology also captures design rationale including joint intent and spatial relationships.

As the importance of software to society has grown, more and more schools worldwide teach coding basics in the classroom. Despite the rapid spread of coding instruction in grade schools, experience in the classroom is certainly limited because there is a gap between the curriculum and the existing computing environment such as the mobile and cloud computing. We propose an approach to fill this gap by using a mobile environment and the robot on the cloud-based platform for effective teaching. In this paper, we propose an architecture called Cloudboard that enables knowledge sharing and collaboration among knowledge providers in the cloud-based robot platforms. We also describe five representative architectural patterns that are referenced and analyzed to design the Cloudboard architecture. Our early experimental results show that the Cloudboard can be effective in the development of collective robotic systems.

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.

It is desirable to invest in wine that increases its value, but wine investment itself is unfamiliar in Korea. Also, the process itself is unreasonable, and information is often forged, because pricing in the wine market is done by a small number of people. With the right solution, however, the wine market can be a desirable investment destination in that the longer one invests, the higher one can expect. Also, it is expected that the domestic wine consumption market will expand through the steady increase in domestic wine imports. This study presents the consortium block chain framework for revitalizing the wine market and enhancing transparency as the "right solution" of the nation's wine investment market. Blockchain governance can compensate for the shortcomings of the wine market because it guarantees desirable decision-making rights and accountability. Because the data stored in the block chain can be checked by consumers, it reduces the likelihood of counterfeit wine appearing and complements the process of unreasonably priced. In addition, digitization of assets resolves low cash liquidity and saves money and time throughout the supply chain through smart contracts, lowering entry barriers to wine investment. In particular, if the governance of the block chain is composed of 'chateau-distributor-investor' through consortium blockchains, it can create a desirable wine market. The production process is stored in the block chain to secure production costs, set a reasonable launch price, and efficiently operate the distribution system by storing the distribution process in the block chain, and forecast the amount of orders for futures trading. Finally, investors make rational decisions by viewing all of these data. The study presented a new perspective on alternative investment in that ownership can be treated like a share. We also look forward to the simplification of food import procedures and the formation of trust within the wine industry by presenting a framework for wine-owned sales. In future studies, we would like to expand the framework to study the areas to be applied.

With the recent increase in interest in the open science movement in science and technology fields such as open access, open data, and open source, the movement to share and utilize publicly funded research products is materializing and revitalizing. In line with this trend, many efforts are being made to establish and revitalize a system for sharing and utilizing research data, which is a key resource for research in Korea. These efforts are mainly focused on collecting research data by field and institution, and linking it with DataON, a national research data platform, to search and utilize it. However, developed countries are building a system that can share and utilize not only such research data but also various types of R&D-related computing resources such as IaaS, PaaS, SaaS, and MLaaS. EOSC (European Open Science Cloud), ARDC (Australian Research Data Commons), and CSTCloud (China S&T Cloud) are representative examples. In Korea, the Korea Research Data Commons (KRDC) is designed and a core framework is being developed to facilitate the sharing of these computing resources. In this study, the necessity, concept, composition, and future plans of KRDC are introduced.
