  • The astronomical data obtained by observations of celestial objects movements are useful in our daily life. These data - such as 1) sunrise and sunset data, 2) data transformation between lunar calendar and solar calendar, 3) solar eclipse and lunar eclipse data, and 4) sun's altitude and azimuth data - were used to important things in the agricultural society and ancient kingdom. In the modern society, these data have been used continuously for the legal disputes, construction of buildings and the other areas. This is a good example of pure science data using directly in our life. However there are difficulties to public service because all the data were printed as an Almanac. Using MySQL, we constructed web-based service system which makes to use them easily. This database system was made for the quick search using the calculated orbital data of celestial bodies.

  • Anyone curious to easily access and learn Korean history has become interested in Korean history data bases, which will provide accurate and reliable historical information. Furthermore, user demands for information sharing and reusability, available through setting up a semantic web, have been increased, which have taken the shape of linked data. Efforts have been made to construct public data bases containing readily usable contents a user can understand and utilize with ease. They have been produced by several organizations, portal sites, and individuals, trying to deviate from existing mainstreams - expert-based text data bases. A problem with those data bases is that they have not considered such vital factors as the sharing and utilizing of information as a whole. This study suggests a LOD-based Korean history contents implementation system, providing rich information environment by way of multi-dimensional web-data connections. In doing so, this system has tried a historic information circulation service system which is based on information sharing and connecting.

  • Purpose: The purpose of the study is to develop and to evaluate a internet-based social support program for the mothers of congenitally abnormal children. The theoretical basis of the study is the moderating effect model of social support theory (Cobb, 1976). Methods: In first phase, an internet support program was developed according to the practical web development stages proposed by Boling and Frick (2002). In the second phase, the internet support program was provided and evaluated to 18 mothers who reared congenitally abnormal children from March to May 2008. Results: In the first stage, demands of the program were collected from interviews of eighteen mothers of congenitally abnormal children of ages one to three. At the same time, literature review and validity of the contents were also examined. In the second stage, the correspondence of the program contents to the social support needed was also examined. In the third and fourth stages, prototype of the social program was prepared in documents and that of computer program was prepared. In the final stage, an internet-based web site was constructed. The social support provided by the web site were composed of informational support, emotional support and appraisal support including bulletin board system and chatting service. After program development, pre-tests and post-test were performed to investigate the effect of the program on maternal confidence and mood. Data were analyzed using Wilcoxon signed rank test. The analysis showed that maternal confidence of post-test was improved than that of pre-test with statistically meaningful figure (Z=-2.54, p<.05). The positive mood of post-test was also improved than that of pre-test and the result was statistically supported (Z=-2.20, p<.05). Conclusion: It is suggestive that the internet based social support programs is accessible and appropriate service to congenitally abnormal children's mother. It is necessary to develop and use the internet based social support programs in public health system.

  • Since the DoS(Denial of Service) attack is still an important vulnerable element in many web service sites, sites including public institution should try their best in constructing defensive systems. Recently, DDoS(Distributed Denial of Service) has been raised by prompting mass network traffic that uses NTP's monlist function or DoS attack has been made related to the DNS infrastructure which is impossible for direct defense. For instance, in June 2013, there has been an outbreak of an infringement accident where Computing and Information Agency was the target. There was a DNS application DoS attack which made the public institution's Information System impossible to run its normal services. Like this, since there is a high possibility in having an extensive damage due to the characteristics of DDoS in attacking unspecific information service and not being limited to a particular information system, efforts have to be made in order to minimize cyber threats. This thesis proposes a method for using TTL (Time To Live) value in IP header to detect DDoS attack with IP spoofing, which occurs when data is transmitted under the agreed regulation between the international and domestic information system.

  • The mass collaboration, one of the newest solutions for web-related tasks, has been recognized to be an effective tool for the R&D sectors of the corporates, since the key advantages of crowdsourcing is that the industrial challenges can be shared with the public entities to find proper solutions. This research approaches to the possibility of the design adoption with participation thorough the Internet will positively effect to its process. This research tried to look around the current trend of web 2.0 based services which support the Mass Collaboration method and results of paper related to the Crowdsourcing and design integration. Following to the analysis of web research, we meet the conclusion as just a small number of users' opinion has helped designing new product and service. And we compared it to the conventional design process detail functions, less number of websites support it. However, the result of paper research shows optimistic results of collective design activity. Several cases emphasize that participants were very active to support their thoughts, memories and novel design idea, therefore designer and researchers got enormous help from them and it was better than conventional participatory design in some perspective.

  • In the study, we introduce the trend in domestic and foreign web accessibility, as well as the legal system that ensures web accessibility. Based on Korean Web Content Accessibility Guidelines (KWCAG)1.0, we investigated the web content accessibility of 80 tertiary health-care hospitals and general hospitals in Korea. We evaluated accessibility by combining accessibility-based criteria (ABC) with usability-based criteria (UBC). ABC was limited to an alternative text for Guideline 1, using a small number of frames and keyboard accessibility for Guideline 2. UBC checked the voice service (TTS), resizing text, providing multi-lingual websites, and disclosing web accessibility policy. KADO-WAH2.0 was used for representing the compliance rate. The evaluation result was a considerable improvement from previous results, even though the rate of compliance with web accessibility was generally insufficient. There was a significant difference between those medical centers which did and did not comply with web accessibility. Incidentally, many hospitals were found to have attempted to confront and come to terms with web accessibility. In future, the following factors are advisable for medical centers with publicity or public interest: they must employ active and aggressive promotion of establishment of independent accessibility guidelines to secure web accessibility, they should effect an improvement of the realization of web accessibility, there can be constant education and promotion, and there can be an institutional supplementation, as well as others.

  • Recently, geo-based application services such as location-based commerce or personal navigation are recognized as a kind of common tool on smart-phone, and demands with respect to advanced functions of online map editing linked to value-added contents are increasing. However, the disabled people have severe difficulties to equally use those geo-based services, compared to the normal people's uses. Of course, this situation is almost same to other application fields besides geo-based applications. Web accessibility basically means necessary guideline handling web-based contents for equal uses of web services for all people. W3C has developed and distributed a generalized web content accessibility guideline, and Korean web content accessibility guideline version 2.1 referred it. As well, there is a certificate system operated by public agencies. In spite of this situation, geo-based application field is globally on the very early stage for web accessibility. This work first summarized the concept of web accessibility and Korean guideline, and then presented some practical schemes for the further geo-based applications, focused on web visualization of geo-based contents among numerous implementable application services.

  • After the end of the service of Internet Explorer, the use of ActiveX ended, and the Non-ActiveX policy spread. HTML5 is used as a standard protocol for web pages established based on the Non-ActiveX policy. HTML5, developed in the W3C(World Wide Web Consortium), provides a better web application experience through API, with various elements and properties added to the browser without plug-in. However, new security vulnerabilities have been discovered from newly added technologies, and these vulnerabilities have widened the scope of attacks. There is a lack of research to find possible security vulnerabilities in HTML5-applied websites. This paper proposes a model for detecting tags and attributes with web vulnerabilities by detecting and analyzing security vulnerabilities in web pages of public institutions where plug-ins have been removed within the last five years. If the proposed model is applied to the web page, it can analyze the compliance and vulnerabilities of the web page to date even after the plug-in is removed, providing reliable web services. And it is expected to help prevent financial and physical problems caused by hacking damage.

  • The terrestrial-digital multimedia broadcasting(T-DMB) is now provided for the public service and the number of receivers reaches 15 million at the present of August 2008. The service of T-DMB itself has been succeeded in the presence. It is however remained as a supplementary role of stationed TV. It is necessary to find an additional business model as a new media to acquire surplus escaping from the deficit of the present T-DMB service. In the present paper, data service of T-DMB is proposed as candidate of such solution. Especially, TTI(Traffic and Travel Information) service is proposed as a killer application using TPEG(Transport Protocol Experts Group). At present, TPEG has not been so popular in the sense of various user satisfaction. Thus the variety of service including bi-directional service using DMB2.0 as in the sphere of Web2.0 is necessary for the service providers. In the paper, the restriction of TPEG-POI(Point of Interest) application service using the conventional mobile communication infrastructure is indicated. To overcome such restriction, TPEG-UCM(User Created Message) application service model using individual bi-directional media which is initiated and interacting by the users is proposed. In the experiment, the application program shows the usability of the proposed method so that the implementation results show its operability.
