Bioworks is designed to make, visualize, automate and execute a model of biological analysis processes as a workflow in biotechnology field. It provides for constructing a workflow model of complex biological analysis processes more easily and reporting the analysis results of each step. Users can perform their analysis process by using a visuality and validation module provided as a plug-in program. It supports sharing their workflow in XML format, to which conversion is supplied by Bioworks, with Web Services to improve the efficiency of their study.

In existing educational systems, it is impossible to synchronize multimedia contents and it is required additional client applications. SMIL(Synchronized Multimedia Integration Language) is based on XML which allows to arrange multimedia objects temporally and spatially, and it can represent multimedia effectively on Web browsers. It is possible to serve the high-quality multimedia on Web browsers by applying SMIL to the previous Web-based educational contents without any client applications. In this paper, we propose the method of developing multimedia educational contents applied by SMIL, and design an authoring tool with a function of transforming SMIL documents to XHTML documents. The tool allows common users to use easily without any plug-ins or applications.

The VMSS(Virtual Makeup Simulation System) is a virtual simulation system which can apply makeup, hair style, accessory to user's own face image through internee connection. The simulation result can be stored to server side DB and also can be printed out on client side printer. It is implemented using Java so, clients don't need any other client program to run the VMSS except Web browser and Java Plug-in installed on browser. IIS (Internet Information Server) Web server of Window 2000 and MS-SQL 7 are used to develop the overall system. Commercial JDBC Driver Type 4 is used to connect the applet and DB. It suggests a new direction of Web-based contents service development and can be applied to many other areas.

C programming is a main programming for the Educational Robot Arm which is based on AVR ATmega128. The development environment is not integrated, so it is complex and difficult to study for middle or high school students who want to learn programming and control the educational robot arm. Furthermore, there is no debug and testing environment support. This paper presents a Java-based development platform for the educational robot arm. This platform includes: an up-to-date tiny Java Virtual Machine (NanoVM) for the educational robot arm; An Eclipse based Java integrated development environment as an Eclipse plug-in; a 3D simulator on the PCs to support testing and debugging programs without real robots. The Java programming environment makes development for educational robot arm easier for students.

This study aims to explore the status and adoption pattern of next generation OPAC functionalities employed in Korean academic libraries. The paper is useful for future planning of next generation OPAC in academic libraries. This study firstly extracted major functionalities of next generation OPAC by reviewing literature and then the pilot test was conducted to validate them. The websites of 191 academic libraries in Korea were surveyed. For the accuracy of the data, the two researchers examined in redundant. The collected data were analyzed using PASW Statistics 18. 'Simple search box' was found to be the most popular function. The second popular function was 'search within results'. A few libraries used the 'clustering', 'open search plug-in', 'sort by relevance', and 'correct spelling error'.

The authentication system of the PKI(public key infrastructure) provides the authenticity and security, accessibility, economic feasibility, and convenience to the service provider and users. Therefore the public and private companies in Korea widely use it as the authentication method of the web service. However, the safety client system is threatened by many vulnerable factors which possibly caused when using PKI-based authentication system. Thus, in this article vulnerable factors caused by using the PKI-based authentication system will be analyzed, which is expected to be the useful data afterwards for the construction of the new authentication system as well as performance improvement.

WebGL is a cross-platform web standard for a low-level 3D graphics API based on OpenGL ES 2.0 and presents 3D graphics in web browsers without installing extra plug-ins. The reason that WebGL is notable is because it is included in the HTML5 standard which is getting the spotlight as a next-generation RIA(Rich Internet Application) platform for variable devices such as PCs, smart phones, table PCs, and smart TVs. In this research, we would like to introduce and develop a behavior engine for easy and rapid authoring of complicated interactions and 3D object's behavior models in WebGL-based contents.

WebRTC(Web Real-Time Communication)는 플러그인의 도움 없이 간단한 웹 표준 API(Application Programming Interface)를 이용하여 웹 브라우저 환경에서 Peer-to-Peer 실시간 통신을 가능케 하고자 하는 기술이다. 실시간 통신으로 오디오, 비디오 스트림은 물론이고 데이터 스트림을 포함한다. 해당 기술은 브라우저간에 직접적으로 Peer-to-Peer 세션을 형성하여 스트리밍을 수행하므로 중계 서버를 이용하는 통신에 비하여 향상된 네트위크 성능을 보이지만 연결을 구성하기 위한 보조 기술들이 요구된다. WebRTC 는 웹 기반 기술이기 때문에 기존의 웹 어플리케이션이 가지는 장단점을 공유한다. 본 논문에서는 WebRTC 기술과 해당 기술을 구성하고 있는 세부 기술들의 구조 및 기능을 분석한다. 또한 해당 기술을 이용하여 간단한 컨퍼런스 시스템을 설계하고 구현한 예제를 보인다.

The national accredited certificate is a user certificate issued based on the user's personal information, which has been identified in advance, and has become a universal authentication method used for most electronic financial transactions and user authentication. And it contributed a lot to the use of e-government and domestic service. However, due to the lack of web standards on how to use, it was inconvenient to install a separate plug-in, and efforts to improve it have been continued. In this paper, we attempt to solve the problem of certificate usage environment by presenting the certificate digital signature method using the extension of the FIDO2 (Fast Identity Online v2) client to authentication protocol (CTAP) specification.
