  • Web robot is an important Internet software technology used in a variety of Internet application software which includes search engines. As Internet continues to grow, implementations of high performance Web robots are urgently demanded. For this, researches specially geared toward performance scalability of Web robots are required. Hoover, because researches are focused mostly on addressing issues related to commercial implementations, scientific researches and studies are not still made on the performance scalability. In this research, Ive choose a Web robot model implemented by fork-join based. multiprocesses. With respect to the model, we evaluate the effect on the collection efficiency that the timeout values set to requests from Web robots to Web servers have. Also, we analysed the behaviors of Web robots by comparing the execution time between the URL extraction and the uniqueness checking for the extracted URLs. as well as by comparing between the computation time and the network time. Based on the analysis result, we suggest the direction for the design of high performance Web robots.

  • This paper discusses an issue of serious security risks at web log which contains private information, and suggests solutions to protect them. These days privacy is core information to produce value-added in information society. Its scope and type is expanded and is more important along with the growth of information society. Web log is a privacy information file enacted as law in South Korea. Web log is not protected properly in spite of that has private information It just is treated as residual product of web services. Many malicious people could gain private information in web log. This problem is occurred by no classified data and improper development of web application. This paper suggests the technical solutions which control data in development phase and minimizes that the private information stored in web log, and applies in operation environment. It is very efficient method to protect private information and to observe the law.

  • A web-based information management system to share engineering data of truss bridge is developed through construction of standardized database of truss bridge. 3D shape information is stored in database according to AP 203 of STEP, and 3D visualization on the web is implemented by using the web 3D technology that helps users to understand geometrical shape of structures, directly. AP209 is used to store structural analysis information such as finite elements, material properties, and analysis result into relational database. Based on the developed database, a prototype of integrated information management system for truss bridge is developed, and it provides additional information such as specifications and inspection information related with shape object to end users.

  • USN(Ubiquitous Sensor Network) environment that provides the service measured from sensors in real-time the information is delivered to application service. However, domestic service, application service provider environment between providers and users, most of the research are on the service platform architecture, and process the information detected by sensors between the providers of standard services platform architecture, which is a very weak level. In this paper, we proposed new service architecture though analysis of the OGC SWE(Sensor Web Enablement) with standards and research analysis of domestic standards. And we designed and implemented to each component of provider side.

  • Purpose: The purpose of this study is to develop a 12-week web-based obesity management program for elementary school students and to evaluate the appropriateness of the developed program from experts and users. Methods: The development of a web-based obesity management program proceeded through the stages of analysis, design, development, and evaluation. After the application of the web-based obesity management program, the evaluation of appropriateness were conducted for knowledge of obesity, obesity control behavior and satisfaction of the program. Collected data has been analyzed using SPSS 19.0. Results: The name of the program developed by this study is healthful weight management and its URL is http://ihealth.or.kr. There were 6 major menus and 18 sub menus including diet, exercise and behavior modification in this program. This study showed that this web-based obesity management program had high satisfaction for a system and increase knowledge of obesity and obesity control behavior for obese children. Conclusion: We expect the web-based obesity management program for elementary school students developed by this study will be able to lead the practice and participation of obese children and decrease the degree of obesity.

  • Purpose: A user centered web-based mental health management system may be particularly useful in Korea where there is widespread diffusion of personal computers and internet connectivity. The purpose of this paper was to describe the development of a web-based system for mental health management in adolescents using principals of a user centered design. Method: Our design process includes five distinct phases: needs assessment, analysis, design, development/testing/revision, and application release. Results: Web content includes an introduction, information about mental health management in adolescents, self-assessment and guidance, interventions for improving mental health, directory of self-help groups, and counseling and additional community resources. The web site was released using the URL: http://www.baejy.com/youth. Conclusion: The end result was a web based mental health management system for adolescents with a high degree of usability. The author believes that web-based mental health interventions in the future have true potential in helping Koreans who are suffering, or at risk, for mental health problems, particularly because of the stigma related to psychiatric therapy in Korea.

  • A procedure for critical buckling moment of a tapered beam is proposed with the application of potential energy calculations using Ritz method. Respective solution allows to obtain critical moments initiating lateral buckling of the simply supported, modestly tapered steel I-beams. In particular, lateral-torsional buckling of beams with simultaneously tapered flanges and the web are considered. Detailed, numerical, parametric analyses are carried out. Typical engineering, uniformly distributed design loads are considered for three cases of the load, applied to the top flange, shear centre, as well as to the bottom flange. In addition simply supported beam under gradient moments is investigated. The parametric analysis of simultaneously tapered beam flanges and the web, demonstrates that tapering of flanges influences much more the critical moments than tapering of the web.

  • The enterprise find a solution to the problems such as a reduction of manufacturing period, accurate analysis for customer demand, improvement for customer service and rise of manufacture accomplishment. Internet is a good solution to such problems. Internet offers WWW(World Wide Web), remote control, file transfer and e-mail service. Among the services, WWW takes large portion because of convenient GUI, easy information search and unlimited information registration. Remote Monitoring Server(RMS) system that uses network service is constructed for chip mounter. Hardware base consists of RMS, chip mounter and C/S(Customer Service) server. Software includes DBMS and various modules in server home page. This provide product number, bad product number, trouble code, content and countermeasure in real-time information module, user information in setup module, detailed error information in fault diagnosis module, fault history in fault history module and customer information in customer service management module.
