PC grid computing is a paradigm of distributed computing that are collection the idle resource of numerous PCs to perform large-scale. As this way, created high performance resources use a large-scale computational application, also this paradigm studied new measurement in place of application using super computer. This paper suggests ORRS(Open Resource Registration System) that selects a adequate resource what application client want. This system register descriptions of resource that provide group, such as organization, party, team, PCs idle resource in open archive. Also, this system provide PC grid computing environment which is select suitable resource actively what application client want.

반도체 기술 및 방송통신기술의 발달에 따라 소비자는 복잡하고 다양한 서비스 환경을 접하고 있으며, 개인당 소비되는 콘텐츠의 양은 기하급수적으로 증가 되고 있다. 스마트폰과 같은 멀티미디어기기의 발전으로 기존의 단순 시청에서 벗어나 멀티미디어 검색과 추천과 같은 다양한 서비스들이 제공되고 있으며, 웹과 인터넷을 기반으로 하는 정보기술은 모바일 전자 기술의 발달에 따라 데스크톱이라는 공간적인 한계를 벗어나 유기적인 유비쿼터스 환경으로 변화하고 있다. 이와 같이 소비자들이 접하는 멀티미디어의 양이 증가됨에 따라, 멀티미디어를 검색하기 위한 다양 서비스들이 사업자들을 통해 제공되고 있다. 그러나 사업자들이 구축한 서버들은 공유되어지지 못하며, 공유되더라도 공유하기 위한 방법이 제각각이다. 이에 MPEG에서는 멀티미디어 콘텐츠를 검색하기 위한 질의 구조를 표준화 하여, 서비스 제공자 및 소비자들에게 유용한 검색 인터페이스를 제공하였다. 이에 본 논문에서는 MPEG Query Format에 기반 하여 임베디드 환경에서 광대한 양의 음악 콘텐츠에서 사용자가 원하는 허밍 질의를 편리하게 검색하기 위한 방법을 성계 및 구현한다.

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.

As the recent advanced in BIO signal measurement technology, our computing platform is rapidly shifting from desktop PCs to Embedded System. Therefore, In this paper introduces an implementation of the same precision as a hospitan ECG system on the Android. The most important fact of the hospital system is connectivity among the PC such as separate means of communication, we can eliminate the separate means of communication through the Porting Embedded System on Android that can be receive ECG signal directly. We also implementation ECG App on Android that can analyze and show the data result directly.

Communication through smartphones is creating a new paradigm of mobile communication beyond the restrictions of mobility and space. The mobile instant messengers of the smartphone, which began on the desktop environment, are providing various communication features, including multimedia contents, texts, and voice. Kindergartens and nurseries are using Websites, phones, SMS, printed materials, handwritten notifications, etc. to communicate with the parents. IsPlus was developed to facilitate the communication between the parents and the teachers, including exchanges of pictures and videos, chatting, and attendance management using smartphones. This is meaningful in that it is an early smartphone mobile messenger for educational institutions for infants and preschoolers. This study presented a new approach to the development of a mobile messenger for a specific group of users by analyzing the user environment, communication types, application planning process and interface design development using storytelling.

DLP technology has been effectively enforcing privacy protection policy in on-line computing environment. However, with wide spread use of smart devices and promotion of smart-works, it has been pointed out that DLP technology cannot effectively prevent privacy leakage at smart devices and is comparatively weak at APT attack. In this paper, we suggests a hybrid approach, PPS, which integrates E-DRM system with DLP technology, taking advantages of both technologies. The technology basically uses encryption function and access control of E-DRM system, and thus it can effectively prevent leakage of privacy information of customers, even if the documents are in the hands of malicious third parties.

인터넷 활용이 다양해짐에 따라서, 사이버 상의 특정 조직에 대한 표적공격에서부터 불특정 다수에 대한 공격까지 불법적인 경로를 통해 목적을 달성하거나 금전적인 이득을 취하기 위한 사이버 공격기법은 갈수록 그 경로가 다양해지고 치밀해지고 있다. 스마트폰의 등장과 함께 휴대용 기기의 사용은 급증하였고, 휴대성과 편리성은 많은 사람들의 서비스 이용환경을 데스크톱환경에서 이동환경으로 변화되고 있다. 이러한 환경의 변화는 보안위협 경로를 확장시킨다. 지능적이고 다양해진 보안 위협으로부터 조직의 시스템에 대한 통합적 가시성을 확보하는 일은 위협에 대비할 수 있는 방법을 제공할 수 있게 된다. 본 연구에서는 보안위협이 될 수 있는 상황을 탐지하기 위해서 조직의 특성에 맞는 보안정책을 수립하는 방법에 대해 정리하고 이에 따른 보안 관제와 운영을 할 수 있는 시스템 설계 방법을 제안하고자 한다.

This study analyzed the most frequently used navigation cases in a desktop environment. As a result of the research, GNB induces users' search as the top element of the search structure and can place color, text, icon, and image elements. LNB could be classified in the form of a dropdown, flyout, dropline and mega menu. In this study, the navigation structure of Interpark and Interpark among open markets used by users was analyzed. G-Market's GNB has a two-tier structure with color, text, image, and icon elements, and Interpark has a three-tiered horizontal label. Interpark's GNB drew attention by placing a badge on the seasonal label, which is a temporary content section, unlike G-market. It can be seen that the LNBs of both shopping malls have flyout menus that protrude when you mouse over the category menu arranged in a vertical text form under the logo placed on the left. The flyout menu has a complex structure consisting of the layout of the mega menu. This study is meaningful in revealing user experience elements by analyzing the GNB and LNB of shopping malls these days where internet shopping is increasing.

Currently, we stand between computers as creative tools and computers as creators. A new genre of movies, which can be called a post-cinema situation, is emerging. This paper aims to diagnose the possibility of the emergence of AI cinema. To confirm the possibility of AI cinema, it was examined through a case study whether the creation of a story, narrative, image, and sound, which are necessary conditions for film creation, is possible by artificial intelligence. First, we checked the visual creation of AI painting algorithms Obvious, GAN, and CAN. Second, AI music has already entered the distribution stage in the market in cooperation with humans. Third, AI can already complete drama scripts, and automatic scenario creation programs using big data are also gaining popularity. That said, we confirmed that the filmmaking requirements could be met with AI algorithms. From the perspective of Manovich's 'AI Genre Convention', web documentaries and desktop documentaries, typical trends post-cinema, can be said to be representative genres that can be expected as AI cinemas. The conditions for AI, web documentaries and desktop documentaries to exist are the same. This article suggests a new path for the media of the 4th Industrial Revolution era through research on AI as a creator of post-cinema.

We propose a method that combines learning in a virtual environment and a real environment for indoor autonomous driving through reinforcement learning. In case of learning only in the real environment, it takes about 80 hours, but in case of learning in both the real and virtual environments, it takes 40 hours. There is an advantage in that it is possible to obtain optimized parameters through various experiments through fast learning while learning in a virtual environment and a real environment in parallel. After configuring a virtual environment using indoor hallway images, prior learning was carried out on the desktop, and learning in the real environment was conducted by connecting various sensors based on Jetson Xavier. In addition, in order to solve the accuracy problem according to the repeated texture of the indoor corridor environment, it was possible to determine the corridor wall object and increase the accuracy by learning the feature point detection that emphasizes the lower line of the corridor wall. As the learning progresses, the experimental vehicle drives based on the center of the corridor in an indoor corridor environment and moves through an average of 70 steering commands.
