  • As Web services need to manage lots of information, it is indispensable to reduce server's load and speed up processing time. In this paper, we analyze the loading problems of server and suggest designing methods for light loaded Web applications based on .NET. The proposed methods include using a relative database to produce minimized modules and Stored Procedures to simplify SQL statements for reducing sever's load. Web pages are organized with scripts replacing server language, which improve server's capability by reducing loads. The execution time is also speeded up by organizing Web pages with User Controls. And XML/EDI is used for managing the effective exchange of documents. The proposed methods are implemented as an education management system and shows its effectiveness.

  • This paper presents a transcoding method that dynamically adapts Web pages to various devices. The proposed method is based on a CC/PP profile that is a standard description of a device's context information. Additionally, to support a sophisticated transcoding, we define an annotation schema for representing additional information about original contents. Since a mobile device has a screen of limited size, A Web page is splitted into many small ones. Our method constructs a navigation-map that represents the hierarchical relations among the splitted pages. Experimental results with various Web contents show that the proposed method is superior in terms of user's convenience of navigation and the transcoding Quality.

  • 최근 무선 인터넷 서비스의 활성화와 함께 모바일 환경에서 브라우저의 사용이 급증하고 있으며, 모바일 사용자들은 PC 수준의 품질을 요구하고 있다. 이에 따라 모바일 웹브라우저도 WAP 방식이 아닌 풀브라우징(full browsing) 방식으로 전환되고 있다. 하지만, 모바일 단말 환경에서 웹브라우저의 성능에는 많은 제약사항이 존재하며, 부족한 메모리, 저 사양의 CPU, 낮은 네트워크 속도, 그리고 브라우저의 엔진 문제 등으로 인해 여전히 사용자들의 브라우저 로딩에 대한 체감 속도는 낮은 편이다. 본 논문에서는 저사양 휴대 단말 환경에서의 브라우저 로딩 속도를 개선할 수 있는 방안을 제시한다. 제안 방식에서는 텍스트와 이미지 등 데이터 타입을 분류하여 부하가 적게 걸리는 텍스트 레이아웃을 먼저 보여줌으로써 사용자의 체감속도를 향상시키고, 아울러 이미지가 커서 렌더링(rendering) 시간이 오래 걸리는 경우 이미지를 축소하거나 화질을 낮추는 방식으로 렌더링 부하를 줄여서 페이지 로딩 시간을 단축시키는 방법을 사용한다. 실험 결과, 제안 기법을 사용하는 경우 현재 사용하는 방법에 비해 이미지가 적은 Web 페이지의 경우 1st drawing 77.04%, full drawing 5.47%, 이미지가 많은 페이지의 경우 26.32%의 로딩 시간을 단축시킬 수 있음을 확인하였다.

  • Client based web mashups have become one of the most important architecture in web application development. Although there are well known methods to generate presentation view codes for web services, navigations between views and service requests are still developed manually in most web mashups. In this paper, we propose the concept of deterministic data binding from output data to input parameters of another method. Using binding relations, we can model navigation menus for service method requests. For a given set of data mappings between services, we investigate context dependent binding conditions and discuss the generation of views and navigation menus. The proposed approach provides UI for users to navigate services of client mashup page using simple and convenient interface even when the number of services and the size of the mashup page grows. In order to show the usability of the proposed approach, we present a historic tourism service.

  • The Internet has become a part of our lives. As the number of devices with Internet accessibility increases, users can use web services with those devices anytime, anywhere. Web contents on the web page can be delivered to user in various forms for various devices and users want to use seamlessly the contents with an appropriate device. Web browser extension is function to add features that are not supported by default browser. All browsers support extensions that provide the same services for cross-browser. In this paper, We proposed object migration architecture between heterogeneous browsers by expanding our proposed mechanism that identifies objects and the information of those objects to be migrated in the web page, extracts the object and creates object after migration. For this purpose, we analyzed the extension architecture of representative browsers and investigated necessary files to develop objects migration extension. In addition, We investigated how to send and receive message among files in each browser extension and the interaction mechanism among those files. Finally, We implemented the object migration mechanisms between heterogeneous browsers.

  • 대규모 웹 캐시 서버의 자원 이용도는 네트워크와 디스크 I/O 대기 시간에 주로 의존하고 또한 작업 부하 패턴에 있어 네트웍 사용이 폭주하는 시간과 새벽과 같은 한가한 시간간의 변동성이 심하다. 따라서, 한정된 자원범위에서 최상의 서비스를 제공키위해서는 절정기 동안 자원 이용도를 낮추고 이들 작업부하를 비절정기 때에 나누어 수행토록 함으로써 자원 활용도를 최대로 끌어 올리자는데, 연구의 목적이 있다 이를 위해 비절정기 동안 캐시압축 기법을 이용하여 디스크 입출력 작업을 미래예측 기법은 어느 점에서의 실제 작업 세트가 작았다는 것과 페이지 재사용 패턴의 정확한 예측은 물리적 메모리 크기의 캐시에서 높은 히트율을 생산할 것이라는 점을 보여주었다.

  • This paper presents a new web cluster scheme based on dispatcher which does not depend on operating system for server and can examine server's status interactively. Two principal functions are proposed for new web cluster technique. The one is self-controlled load distribution and the other is transaction fail-safe. Self-controlled load distribution function checks response time and status of servers periodically, then it decides where the traffic goes to guarantee rapid response for every query. Transaction fail-safe function can recover lost queries including broken transaction immediately from server errors. Proposed new web cluster scheme is implemented by C language on Unix operating system and compared with legacy web cluster products. On the comparison with broadcast based web cluster, proposed new web cluster results higher performance as more traffic comes. And on the comparison with a round-robin DNS based web cluster, it results similar performance at the case of traffic processing. But when the situation of one server crashed, proposed web cluster processed traffics more reliably without lost queries. So, new web cluster scheme Proposed on this dissertation can give alternative plan about highly increasing traffics and server load due to heavy traffics to build more reliable and utilized services.

  • Social media has become one of the most popular media in web and mobile application. In 2011, social networks and blogs are still the top destination of online users, according to a study from Nielsen Company. In their studies, nearly 4 in 5active users visit social network and blog. Social Networks and Blogs sites rule Americans' Internet time, accounting to 23 percent of time spent online. Facebook is the main social network that the U.S internet users spend time more than the other social network services such as Yahoo, Google, AOL Media Network, Twitter, Linked In and so on. In recent trend, most of the companies promote their products in the Facebook by creating the "Facebook Page" that refers to specific product. The "Like" option allows user to subscribed and received updates their interested on from the page. The film makers which produce a lot of films around the world also take part to market and promote their films by exploiting the advantages of using the "Facebook Page". In addition, a great number of streaming service providers allows users to subscribe their service to watch and enjoy movies and TV program. They can instantly watch movies and TV program over the internet to PCs, Macs and TVs. Netflix alone as the world's leading subscription service have more than 30 million streaming members in the United States, Latin America, the United Kingdom and the Nordics. As the matter of facts, a million of movies and TV program with different of genres are offered to the subscriber. In contrast, users need spend a lot time to find the right movies which are related to their interest genre. Recent years there are many researchers who have been propose a method to improve prediction the rating or preference that would give the most related items such as books, music or movies to the garget user or the group of users that have the same interest in the particular items. One of the most popular methods to build recommendation system is traditional Collaborative Filtering (CF). The method compute the similarity of the target user and other users, which then are cluster in the same interest on items according which items that users have been rated. The method then predicts other items from the same group of users to recommend to a group of users. Moreover, There are many items that need to study for suggesting to users such as books, music, movies, news, videos and so on. However, in this paper we only focus on movie as item to recommend to users. In addition, there are many challenges for CF task. Firstly, the "sparsity problem"; it occurs when user information preference is not enough. The recommendation accuracies result is lower compared to the neighbor who composed with a large amount of ratings. The second problem is "cold-start problem"; it occurs whenever new users or items are added into the system, which each has norating or a few rating. For instance, no personalized predictions can be made for a new user without any ratings on the record. In this research we propose a clustering method according to the users' genre interest extracted from social network service (SNS) and user's movies rating information system to solve the "cold-start problem." Our proposed method will clusters the target user together with the other users by combining the user genre interest and the rating information. It is important to realize a huge amount of interesting and useful user's information from Facebook Graph, we can extract information from the "Facebook Page" which "Like" by them. Moreover, we use the Internet Movie Database(IMDb) as the main dataset. The IMDbis online databases that consist of a large amount of information related to movies, TV programs and including actors. This dataset not only used to provide movie information in our Movie Rating Systems, but also as resources to provide movie genre information which extracted from the "Facebook Page". Formerly, the user must login with their Facebook account to login to the Movie Rating System, at the same time our system will collect the genre interest from the "Facebook Page". We conduct many experiments with other methods to see how our method performs and we also compare to the other methods. First, we compared our proposed method in the case of the normal recommendation to see how our system improves the recommendation result. Then we experiment method in case of cold-start problem. Our experiment show that our method is outperform than the other methods. In these two cases of our experimentation, we see that our proposed method produces better result in case both cases.

  • Recently, comics pulication industry is experiencing long-time recess in Korean market. To overcome the difficulties firms are trying to develop various tools which fit new technological environments, but previous research tend to have focused too much on web-base contents such as webtoons, rather than communication effectiveness through social network services. Thus, this study investigated the relationship between the characteristics of postings at social network service and the consumer responsiveness. In the results, we found that posting with visual images and event invitations were positively associated with consumer responsiveness, and the amount of information was negatively associated with the responsiveness. This study shows some implications on how firms can effectively enhance communication with consumers through social network service.
