  • With the growth of the Internet, web-based cyber education is progressing from the text-based to the hyper-based including multimedia, and from one way of simply giving the contents to the learner to another way of providing mutual interaction between the instructor and the learner. For this, there uses the RIA-based dynamic application and multimedia. RIA, which is the new paradigm on the web, provides the learners with more effective and rich contents. For developing a cyber education system, if we use the existing web languages, a large amount of effort is needed. But if we use the RIA-based paradigm, we can remarkably reduce the effort. Also, in developing a new web-based cyber education system the RIA paradigm makes the learners to satisfy their demands, and in developing the system providing the interaction the paradigm gives us the way minimizing the time and effort. In this paper, we compare and evaluate the efforts in developing the RIA based education system with the Non-RIA based education system.

  • Current SSO has focused on authenticated integration between inter systems in a domain.On the contrary, becasuse SSO using SAML can support integration between different domains, once it is used in RIA, we can expect highly synergic effect. However, because researches on SSO using SAML are mainly those on authenticated information exchange between servers, a special research is needed in order to be applied in RIA environment, which conducts numerous managements in client. This study proposes architecture and explain a practice structure in order to apply SAML to RIA. Also, this study has embodied the proposed architecture and applied it on DWR, which is used mostly as Data communication framework of RIA, and verified the useablity of this architecture.

  • With the improvement of the web-technology, web-based cyber education is progressing from the text-based to the hyper-based including multimedia, and from one way of simply giving the contents to the learner to another way of providing mutual interaction between instructors and learners. There are several fields using the dynamic application and multimedia contents. RIA(Rich Internet Application), which. is the new paradigm of the web, provides clients with more effective and rich contents, combining the dynamic application and multimedia contents. With the existing web script language, a lot of time and efforts will be very needed to provide learners with various and rich contents. In this paper, we compare the efforts in developing the RIA based education system with the Non-RIA based education system, then experiment the characteristics of the RIA based education system

  • RIA(Rich Internet Application) has the best User Interface and easy way to use. It is used in many Application System and Web Application. This Paper introduces a RIA technology for Implementation of u-Hospital Application. This System uses a history of customers in the hospital and question about diseases, so we can improve the satisfaction of service. This paper shows that the u-Hospital System using RIA is more fast and easy than HTML application. Because RIA has special features that data can be obtained from server without reloading entire page and every user interaction does not require web server response. The proposed technology can improve the efficient u-Hospital System because it can be extended to ubiquitous mobile application.

  • As the Internet has been improved to Web 2.0, it introduces new approaches including Rich Internet Application (RIA) technology such as Flash, AJAX, Silverlight, etc. The RIA which is platform independent technology allows applications to provide rich client-side interfaces, and allows the browser to interact with users without communication to server. In this paper, we propose a method of spatial data service based on RIA technology. Internet map service using spatial data generally requires rich client-side interfaces and various interactions. These features can be provided by the RIA. The proposed method uses Flash developed by Macromedia as RIA technology. It can be applicable on any platform including mobile environment. The spatial data server makes Flash file known as SWF (Shock Wave File) with manipulation code for map and spatial data that is requested by user, and send it to the web browser. Once the web browser receives a SWF, client SWF manipulates user interactions, such as zooming and panning, without communication with server. Experiments that execute the application on various web browsers including mobile web browser and measure time of map interaction are carried out to compare with traditional bitmap based WMS (Web Map Service). As a result of experiments, we have confirmed improvement of interactivity and performance with RIA approach.

  • Microfluidic radioimmunoassay (RIA) platform called µ-RIA spends less reagent and shorter reaction time for the analysis compared to the conventional tube-based radioimmunoassay. This study reported the design of µ-RIA chips optimized for the gamma counter which could measure the small samples of radioactive materials automatically. Compared with the previous study, the µ-RIA chips developed in this study were designed to be compatible with conventional RIA test tubes. And, the automatic gamma counter could detect radioactivity from the 125I labeled anti-PSA attached to the chips. Effects of the multi-layer microchannels and two-phase flow in the µ-RIA chips were investigated in this study. The measured radioactivity from the 125I labeled anti-PSA was linearly proportional to the number of stacked chips, representing that the radioactivity in µ-RIA platform could be amplified by designing the chips with multi-layers. In addition, we designed µ-RIA chip to generate liquid-gas plug flow inside the microfluidic channel. The plug flow can promote binding of the biomolecules onto the microfluidic channel surface with recirculation in the liquid phase. The ratio of liquid slug and air slug length was 1 : 1 when the 125I labeled anti-PSA and the air were injected at 1 and 35 µL/min, respectively, exhibiting 1.6 times higher biomolecule attachment compared to the microfluidic chip without the air injection. This experimental result indicated that the biomolecular reaction was improved by generating liquid-gas slugs inside the microfluidic channel. In this study, we presented a novel µ-RIA chips that is compatible with the conventional gamma counter with automated sampler. Therefore, high-throughput radioimmunoassay can be carried out by the automatic measurement of radioactivity with reduced radiowaste generation. We expect the µ-RIA platform can successfully replace conventional tube-based radioimmunoassay in the future.

  • RIA(Rich Internet Application)는 기존의 웹 애플리케이션 기술이 가진 평면적인 표현과 순차적인 프로세스를 다이나믹한 사용자 인터페이스와 데이터베이스의 연동을 통해 저렴한 비용으로 하나의 인터페이스에서 모든 프로세스가 처리 가능하도록 해주는 기술을 의미한다. 본 논문에서는 웹 표준(HTML/CSS)을 RIA로 확장한 문법을 해석 할 수 있는 RIA Generator를 제안한다. RIA Generator는 크게 두 부분으로 나뉘는데, 한 부분은 기존 HTML 및 CSS 소스와 확장된 RIA 문법을 파싱하는 부분이고, 나머지 한 부분은 파싱한 것을 의미에 따라 화면에 적절히 출력하는 부분이다.

  • 인터넷의 확산으로 소프트웨어 산업구조는 패키지 방식에서 웹을 중심으로 한 방식으로 변화되었다. 소프트웨어 배포 및 사용이 웹을 통해 이루어지고 사용자들도 자신이 원하는 콘텐츠를 직접 제작할 수 있게 되었다. 이와 더불어, 웹 기반 소프트웨어에 대한 사용자 요구사항도 더욱 많아졌다. 사용자들은 멀티미디어 지원, 상호작용, 데스크톱 수준의 시각적으로 화려한 인터페이스(UI)를 웹 브라우저를 통해 사용하기를 원한다. 하지만, HTML과 스크립트 언어 기반의 웹 시스템 만으로는 사용자 요구사항을 만족시키기가 어렵다. RIA(Rich Internet Application)는 HTML의 한계를 극복하고, 사용자 요구사항을 충족시키기 위해 제안된 모델이다. 향후 RIA 기술은 많은 분야의 소프트웨어 개발에 사용될 것이다. 본 논문에서는 RIA 기술에 대해 알아보고 RIA 개발을 위해 필요한 요소들을 정의하고 RIA 개발환경들의 장단점을 비교 평가한다. 또한 각 플랫폼의 성공적인 응용사례를 살펴봄으로써 RIA 개발환경 선택에 도움을 주고자 한다.

  • The established methods in the residue analysis of endosulfan require an extensive sample clean-up prior to quantification by relatively complex equipment. A radioimmunoassay(RIA) provides a simple procedure with theoretically higher sensitivity and specificity necessitating only a minimum of sample clean-up. Endosulfan-specific antibodies were developed in rabbits by using a bovine serum albumin(BSA) conjugate wherein the alcohol form of endosulfan was multiply bound to the protein via succinylation. Produced antibodies showed the high titers to endosulfan-BSA(1 : 32,000). An RIA method was developed in water and carp by using $^{14}C-labeled$ endosulfan as a tracer. The lowest detection amount of endosulfan was 1 ng in the liver, kidneys, gut and water samples, and 3 ng in the whole body sample of carp without any clean-up, corresponding to 0.1 ppb of endosulfan.
