For a Web, it can be a communication-rich environment that helps educaitonal dialogue among participants, including learners, instructors, and instructional materials. As an example, this study is intended to show a "classroom homepage" which provides even users with cyber place for educational communications. Within this Webpage, users can share available educational materials, experiences, opinions about specific matters and even their serious problems. The existence of this kind of communication channel helps to motivate every users to consider others' situations and understand one another. This Webpage called classroom homepage is suggested as a prototype for enjoying possible educational activities from the perspective of learners.

3D Conversion은 3DTV 및 3D Display에 장착되어 제공되고 있다. 이외에도 다양한 변환 방법이 제안되어 왔다 기존 방법들은 영화나 애니메이션 같은 자연영상을 3D로 변환하는 것에 초점이 맞추어져 있었다. 따라서 자동 3D변환에서는 webpage영상처럼 텍스트, 이미지, 로고 등의 혼재되어 있는 영상을 처리하는데 어려움이 있다. 특히 텍스트는 동일한 깊이맵을 얻지 못하면, 깨짐, 흔들림 등의 문제점이 발생한다. 해결방법으로 webpage에서 image region만을 탐색해서, 3D변환을 하고, 다른 영역은 2D로 처리함으로써 상기 문제점을 극복할 수 있다. 이를 위해 본 논문에서는 변환하려는 영상 영역을 탐색하고 이 탐색된 영상들을 단순하게 픽셀의 수평이동이 아닌, 양선형 보간으로 변환하여 홀채움 문제를 극복할 수 있는 변환방법을 제안한다.

This paper proposes the web robot based on Multi-Agent which the mutual dependency should be minimized each other with dividing the function each to collect Webpage. In result it is written to make a foundation for producing the effective statistics to analyze the domestic webpages and text, multimedia file composition ratio through performance analysis of the implemented system. It is easy that Web robot of the sequential processing method to collect Webpage on the same resource environment produces the limit of collecting performance. So to speak Webpages have "Dead-links" URL which is produced by the temporary host down and instability of network resource. If there are much "Dead-links" URL in the webpages, it takes a lot of time for web robot to collect HTML. The propose of this paper to be proposed, makes the maximum improvement to extract the webpages to process "Dead-links" URL on the Inactive URL scanner Agent.

업무의 효율성을 증대하기 위해서는 주변 환경의 개선이 필요하다. 미국 냉난방 공조학회(ASHRAE)에서도 실내 환경이 업무에 미치는 영향을 발표하고 기준치를 제시했다. 이를 바탕으로 TES-1370, TES-1355센서를 이용하여 주변 환경의 '온도, 습도, co2, 소음'을 측정하고, 측정된 데이터를 가공하여 WEBPAGE와 MOBILE-WEBPAGE에서 차트와 함께 어디서든 쉽게 환경을 모니터링 할 수 있는 실내 환경 모니터링 시스템을 구축한다. 개발된 시스템으로 도서관과 강의실의 주변 환경을 모니터링을 했다.

As the performance of mobile devices has increased, high-end multicore CPUs have become the norm in smartphones. However, such high performance devices are exposed to the problem of battery depletion due to the energy consumption caused by software performance, and despite increases in battery capacity. The required resources are dynamic and varied, and further user interaction is highly random; thus, Linux-based power management such as DVFS is needed to fulfill requirements. In order to reduce power consumption, we propose a method to restrict the CPU frequency of data download while maintaining user reactivity. This can supplement the weakness of existing Linux-based power management techniques like DVFS in relation to webpage loading. Through the implementation of our method at the application level, we confirm that energy consumption from webpage loading is reduced.

We have constructed a database of Korean historical astronomical records. The database contains observational data recorded from BC 2183 to AD 1910. We have also built a webpage for searching through the database based on the following criteria: (1) dynasties (2) astronomical phenomena (3) reigning kings (4) references (5) keywords. Users may select two or more dynasties to search through the database for a certain phenomena, and compare data with those of other dynasties. The queried data can be primarily sorted by one critetion, and secondarily sorted by another, each in ascending or descending order. The search results give dates both in Solar and Lunisolar calendars, years and dates in Sexagenary cycle, dynasties, reigning kings, astronomical phenomena, and references. The database and webpage were constructed under the research project of the Korean Astronomical Data Center (KADC, http://kadc.kao.re.kr) in Korea Astronomy Observatory (KAO).

Despite the convenience brought by the advances in web and Internet technology, users are increasingly being exposed to the danger of various types of cyber attacks. In particular, recent studies have shown that today's cyber attacks usually occur on the web via malware distribution and the stealing of personal information. A drive-by download is a kind of web-based attack for malware distribution. Researchers have proposed various methods for detecting a drive-by download attack effectively. However, existing methods have limitations against recent evasion techniques, including JavaScript obfuscation, hiding, and dynamic code evaluation. In this paper, we propose an emulation-based malicious webpage detection method. Based on our study on the limitations of the existing methods and the state-of-the-art evasion techniques, we will introduce four features that can detect malware distribution networks and we applied them to the proposed method. Our performance evaluation using a URL scan engine provided by VirusTotal shows that the proposed method detects malicious webpages more precisely than existing solutions.

Window image is displayed through a monitor screen when we execute the application programs on the computer. This includes webpage, video player and a number of applications. The webpage delivers a variety of information by various types in comparison with other application. Unlike a natural image captured from a camera, the window image like a webpage includes diverse components such as text, logo, icon, subimage and so on. Each component delivers various types of information to users. However, the components with different characteristic need to be divided locally, because text and image are served by various type. In this paper, we divide window images into many sub blocks, and classify each divided region into background, text and subimage. The detected subimages can be applied into 2D-to-3D conversion, image retrieval, image browsing and so forth. There are many subimage classification methods. In this paper, we utilize AdaBoost for verifying that the machine learning-based algorithm can be efficient for subimage detection. In the experiment, we showed that the subimage detection ratio is 93.4 % and false alarm is 13 %.
