Ajax based on Java Script receives attention as an alternative to ActiveX technology. Most portal sites in korea show a tendency to reopen existing services by combining the technology, because it supports most web browsers, and has the advantages of such a brilliant interface, excellent speed, and traffic reduction through asynchronous interaction. This paper modeled and implemented a multilingual meta-search service using the Ajax and open APIs provided by international famous sites. First, a Korean query is translated into one of the language of 54 countries around the world by Google translation API, and then the translated result is used to search the information of the social web sites such as Flickr, Youtube, Daum, and Naver. Searched results are displayed fast by dynamic loading of portion of the screen using Ajax. Our system can reduce server traffic and per-packet communications charges by preventing redundant transmission of unnecessary information.

This paper will intend to contribute to extracting and storing various form of information on user interests by using structural rules user makes and XML-based word document converting techniques. The system named PPE consists of three essential element. One is converting element which converts word documents like HWP, DOC into XML documents, another is extracting element to prepare structural rules and extract concerned information from XML document by structural rules, and the other is storing element to make final XML document or store it into database system. For word document converting, we developed OCX based word converting daemon. Helping user to extracting information, we developed script language having native function/variable processing engine extended from XSLT. This system can be used in the area of constructing word document contents DB or providing various information service based on RAW word documents. We really applied it to project management system and project result management system.

There has been many studies to explore what is the best multimedia tools for English learning by internet, but the students are still thirsty for the lack of practical and effective learning method which may lead them to stimulate their motivations to learn English with technological new media. The purpose of this study is to design Flash Animation as a new approach to learn language acquisition for those students who are learning English as a second language. This second is to show the validity for the introduction of Flash Animation into the English class. The third is to describe the effectiveness of the application of multimedia tools used in English communication such as java script programming and power point presentation.

This paper describes the data model and software development of XWS, an XWEET Web-wrapper System for generation wrapper program. To access information from various information sources, one has to convert and integrate source data into the same data model. XWS is developed as a part of XWEET project. We have implemented the XWS system using the Perl programming language stressing efficiency and ease-of-use. XWS has a few distinct features. First, data model and operator used for extracting information from HTML support a unified model of different views of HTML document. Second, it provides a user-friendly interface program to enable wrapper programmer to generate wrapper easily Third, XWS use the high-level script language designed by object-oriented methodology. In this paper, we also present the detail demonstration where it is useful for extracting article information from DBLP site.

Recently the market of smart phone applications grows very fast. And users want more various and rich experiments using enhanced smart phone functions. But the development of smart phone applications is not an easy job. Specially to control smart phone sensors can be realized by using each native programming languages in experts level. Moreover the process needs separate development based on each smart phone OS. Development of the Web-based smart phone application using Web Common APIs, known as 'WebApp', is one of solutions to overcome these problems. The method includes interface constructions with HTML, and Web Common API calls and accesses to smart phone device APIs with Java scripts. In this paper, the experience in development of the smart phone e-book application is introduced, which is implemented with comport and OS independent WebApp development method.

Web-assemblies are a new binary standard designed to improve the performance of Web browser JavaScript. Web-assemblies are becoming a new web standard that can run at near native speed with efficient execution, concise representation, and code written in multiple languages. However, current Web-assembly vulnerability verification is limited to the Web assembly interpreter language, and vulnerability verification of Web-assembly binary itself is insufficient. Therefore, it is necessary to verify the safety of the web assembly itself. In this paper, we analyze how to operate the web assembly and verify the safety of the current web-assembly. In addition, we examine vulnerability of existing web -assembly and analyze limitations according to existing safety verification method. Finally, we introduce web-assembly API based fuzzing method to overcome limitation of web-assembly safety verification method. This verifies the effectiveness of the proposed Fuzzing by detecting crashes that could not be detected by existing safety verification tools.

This paper proposes a model to detect depression-related emotions in a user's speech using wellness dialogue scripts provided by AI Hub, topic-specific daily conversation datasets, and chatbot datasets published on Github. There are 18 emotions, including depression and lethargy, in depression-related emotions, and emotion classification tasks are performed using KoBERT and KOELECTRA models that show high performance in language models. For model-specific performance comparisons, we build diverse datasets and compare classification results while adjusting batch sizes and learning rates for models that perform well. Furthermore, a person performs a multi-classification task by selecting all labels whose output values are higher than a specific threshold as the correct answer, in order to reflect feeling multiple emotions at the same time. The model with the best performance derived through this process is called the Depression model, and the model is then used to classify depression-related emotions for user utterances.

소프트웨어 개발의 생산성을 높이고 신뢰성 있는 프로그램을 개발하기 위하여 테스트 자동화에 대한 연구가 활발히 진행되고 있다. 임베디드 소프트웨어는 일반 소프트웨어 개발 환경과는 달리 호스트-타겟(host-target) 구조의 교차 개발환경에서 개발이 이루어지고 있다. 본 논문은 임베디드 소프트웨어의 개발 환경에 맞추어 제한된 자원의 특성을 고려한 원격 단위 테스팅 도구를 제안한다. 제안하는 원격 단위 테스팅 도구는 XML 테스트 스크립트를 기반으로 대상 소스 언어에 맞는 테스트 드라이버를 생성하여 테스트 대상과 함께 테스트 작업 용구(Test harness)를 생성한다. 이러게 생성된 테스트 작업 용구는 이더넷(ethernet)을 통해 타겟(target)으로 전송되어 테스트를 수행한 후, 테스트 결과 로그를 호스트로 전송한다. 호스트에서는 로그를 수집하여 XML형태의 파일로 제공하여 다양한 형태의 리포트 뷰(View)를 가능하게 한다. 본 논문의 원격 단위 테스팅 도구는 임베디드 소프트웨어 개발 단계에서 반복적인 단위 테스팅의 절차를 간소화 하여 보다 효율적이고 신뢰성 있는 임베디드 소프트웨어 개발의 기회를 제공 할 것으로 기대된다.

WebCL was proposed for high complex computing in Javascript. Since WebCL-based applications are distributed and executed on an unspecified number of general clients, it is important to profile their performances on different clients. Several profilers have been introduced to support various programming languages but WebCL profiler has not been developed yet. In this paper, we present a WebCL profiler to evaluate WebCL-based applications and monitor the status of GPU on which they run. This profiler helps developers know the execution time of applications, memory read/write time, GPU statues such as its power consumption, temperature, and clock speed.

As Web services need to manage lots of information, it is indispensable to reduce server's load and speed up processing time. In this paper, we analyze the loading problems of server and suggest designing methods for light loaded Web applications based on .NET. The proposed methods include using a relative database to produce minimized modules and Stored Procedures to simplify SQL statements for reducing sever's load. Web pages are organized with scripts replacing server language, which improve server's capability by reducing loads. The execution time is also speeded up by organizing Web pages with User Controls. And XML/EDI is used for managing the effective exchange of documents. The proposed methods are implemented as an education management system and shows its effectiveness.
