This study intended to examine the nature of image which uses the network as the medium in the context of 'post-internet art' and categorize and analyze the cases of applications within art images. In the post-internet art which embraces the background of Web 2.0 and extended digital and network environment, image is transformed and re-mediated into various formats beyond fixed forms. Hito Steyerl defined the image, copied, downloaded, and reedited digitally in low quality as 'poor image.' Young artists, the digital native generation, capture and re-contextualize the changed network environment and depict it in various images. In this context, the application of image in post-internet art can be categorized and analyzed into the 'Image Collected as Material' produced by collecting and recomposing images found in social media, operating system, and website, 'Image Processed through Work' which is newly processed and re-contextualized by using editing programs, and 'Combined Digital-Reality Image' which represents the section of the digital society as the film and image that combine virtuality and reality.

The advantage of the distance learning universities based on the 4th Industrial Revolution is that anyone can conveniently take lectures anytime, anywhere on the web. In addition, research has been actively conducted on the effect of light color and temperature control upon student performance during online classes. However, research on how the conditions of subjects, lighting colors, and music selection improve the degree of a student's concentration during online lectures has not been completed. To solve these problems in this paper, we have developed automatic analysis system SW for the weak subjects of learners by applying intelligent analysis algorithm, have proposed and simulated music therapy and art therapy. Moreover, It proposed in this paper an algorithm for an automatic analysis system, which shows the weak subjects of learners by adopting intelligence analysis algorithms. We also have presented and simulated a music therapy and art therapy algorithms, based on the blended learning, in order to increase students concentration during lecture.

인터넷 시대가 가속화 되면서 파편화 되었던 web에 대한 규격 통일을 외치는 목소리가 높아졌고 그에 따른 대안으로 HTML5.0이 부상하게 되었다. 그로인해 Adobe Flash는 통일 규격에 벗어나게 되었고 더 나가 보안에도 문제가 있어 점차 퇴출당하고 있는 실정이다. 이에 대한 대안으로 Adobe사에서는 Edge를 런칭하게 되었다. Edge는 Flash를 대신하여 웹 애니메이션을 빠르게 만들 수 있는 프로그램이며, 웹 전용 디자인 페이지는 간단하면서 효과적인 css 디자인 및 레이아웃 특징을 나타낼 수 있다. 또한 edge는 html5에 대한 전반적인 지식이 없어도 html5 기반이 되는 다양한 애니메이션 결과물들을 만들어 낼 수 있는 장점이 있다. 그리고 edge에서는 Flash 플레이어 플러그인이 없어도 웹 사이트에서 사용이 가능하다. 본 논문에서는 Adobe edge와 HTML 5.0을 비교 분석하여 각각의 장, 단점을 분석해보고, Adobe edge가 어떤 점에 있어서 HTML5.0보다 비교우위에 있는지, 혹은 더 나가 Flash나 HTML5.0의 대체제가 될 수 있는지에 대해 알아보며 프로그래머들 측면이 아닌 디자이너 측면에서 효용성에 대해 알아보고자 한다.

In 21 century information age, teachers have to help students' learning activities can be more self- directed learning. The web with diverse audio-visual materials and a great deal of interactions among contents shows lots of possibilities as one of the methods to provide self-directed learning environment for students. It allows learning environment for students to study more self-directed way by following individual learning styles, need, ability, etc. Although the best instructional method is personal field experience in the view of the characteristic of Practical Arts education. a web courseware can be a great substitutional method for improving learning effectiveness in relation to cost, safety, time limit for direct personal field experience. Therefore, the purpose of this study is to develop a web courseware for the unit 'Raising Animals' in Elementary school 6th grade Practical Art which is very difficult unit for teachers to provide direct experience environment for students. The researchers also applied the web courseware in 6th grade classrooms and described the results briefly. However, the researchers did not intend to conduct a full field implementation of the program to evaluate the program. That will be conducted in a following.

This paper proposes a thread pool management technique of an websocket server that is applicable to embedded systems. WebSocket is a proposed technique for consisting a dynamic web, and is constructed using HTML5 and jQuery. Various studies have been progressing to construct a dynamic web by Apache, Oracle and etc. Previous web service systems require high-capacity, high-performance hardware specifications and are not suitable for embedded systems. The node.js which is consist of HTML5 and jQuery is a typical websocket server which is made by open sources, and is a java script based web application which is composed of a single thread. The node.js has a limitation on the performance for processing a high velocity data on the embedded system. We make up a multi-thread based websoket server which can solve the mentioned problem. The thread pool is managed by a bit register and suitable for embedded systems. To evaluate the performance of the proposed algorithm, we uses JMeter that is a network test tool.

Electric utility companies have the responsibility of providing good electricity for their customers. They have introduced the DAS(Distribution Automation System) to automate the power distribution networks. DAS engineers require state-of-the-art applications, such as a way to actively manage the distribution system and gain economic benefits from a flexible DAS architectural design. The existing DAS is not capable of handling these needs. It requires operator intervention whenever feeder overloading is detected while operator error could cause the feeder overload area to be extended. It also utilizes a closed architecture and it is therefore difficult to meet the system migration and future enhancement requirements. This paper represents a web based, platform-independent, flexible DAS architectural design and active database application. Recent advanced Internet technologies are fully utilized in this new DAS architecture allowing it to meet the system migration and future enhancement requirements. By using an active database, the DAS can minimize the feeder overloading area in the distribution system without operator intervention, thereby minimizing mistakes due to operator error.

Real-time prediction of Web service of quality (QoS) provides more convenience for web services in cloud environment, but real-time QoS prediction faces severe challenges, especially under the cold-start situation. Existing literatures of real-time QoS predicting ignore that the QoS of a user/service is related to the QoS of other users/services. For example, users/services belonging to the same group of category will have similar QoS values. All of the methods ignore the group relationship because of the complexity of the model. Based on this, we propose a real-time Matrix Factorization based Clustering model (MFC), which uses category information as a new regularization term of the loss function. Specifically, in order to meet the real-time characteristic of the real-time prediction model, and to minimize the complexity of the model, we first map the QoS values of a large number of users/services to a lower-dimensional space by the PCA method, and then use the K-means algorithm calculates user/service category information, and use the average result to obtain a stable final clustering result. Extensive experiments on real-word datasets demonstrate that MFC outperforms other state-of-the-art prediction algorithms.

The purpose of this study is to explore possible ways to make a strategical use of CRM(Customer Relationship Management) for facilitating performing arts. In order to satisfy the purpose, this study investigated actual cases of CRM, primarily focusing on LG Art Center, one of representative performance venues in South Korea, and CREDIA, a performing art planning agency in South Korea. Here, it was found that LG Art Center operated its independent TMS(Theater Management System) and thereby could afford to successfully plan performing art programs on the basis of customer-oriented convenient ticketing system as well as a pile of customer information. On the other hand, CREDIA introduced advanced performance management system and has successfully attracted larger membership than before. Moreover, it organized specialized personnel in membership management and thereby could manage membership in systematic manner. And it was found that based on web log analysis, CREDIA developed a variety of products to comply with customer needs and thereby could realize higher returns and better customer satisfaction through cross-selling activities as well as performance ticketing. However, it was found that CREDIA still operated its membership system and mileage point system in stereotypes manner. Thus, it is required to operate differentiated membership system based on membership grades and diversify practical ways to save and use mileage points, so that CRM can be strategically applied to develop new audience and maintain loyal customers.
