The appearance and popularization of Internet changes the existing restrictive management system into the new management system on Web. In this paper, We developed real-time management System controlling all sorts of informations from Dong-Hwa dam. Informations from MMI(Man Machine Interface) is stored for DB and Wherever User can use Internet, User can get this informations. We also developed Editor modifying Client Display.

Various web browsers offer mouse gesture functions because they are convenient input methods. Mouse gestures enable users to move to the previous page or tab without clicking its relevant icon or menu of the web browser. To maximize the efficiency of mouse gestures, they should be designed to match users' mental models. Mental models of human beings are used to make accurate predictions and reactions when certain information has been recognized by humans. This means providing users with appropriate information about mental models will lead to fast understanding and response. A cognitive response test was performed in order to evaluate whether the mouse gestures easily associate with their respective functional meanings or not. After extracting mouse gestures which needed improvement, those were redesigned to reduce cognitive load via sketch maps. The methods presented in this study will be of help for evaluating and designing mouse gestures.

본 논문에서는 인터넷상에 존재하는 네트워크의 특화된 주소인 지정된 URL로 Address Mapping기법을 이용하여 Peer 상호간의 파일공유 및 검색이 가능한 Peer-to-Peer프로그램을 구현하여 보았으며, 이를 응용한 하나의 제안으로써 원격지 상에 존재하는 내 컴퓨터의 저장드라이브를 같은 방법의 URL ID로 제어하여 Server운영체제 없이 개인용 PC를 자료공유용 Server로 활용할 수 있는 방법을 구현하였다. 따라서 기존의 P2P프로그램의 기본기능과 비교하여 Web Blower상에서 원격지 개인 PC의 자료실을 손쉽게 운영할 수 있는 Web Service가 가능하도록 설계하였고, 인터넷 사용자가 손쉽게 파일 검색 및 공유, 저장, 원격제어가 가능하도록 UI에 초점을 맞추어 시스템을 구현하였다.

본 논문에서는 사용자에게 편의성을 제공하며 기존 물물거래 시스템의 단점을 보완한 웹기반의 물물교환 시스템을 제안한다. 대부분 사람들이 중고거래나 필요 없는 물품에 대해 판매를 하는 목적은 자신에게 필요 없는 물건을 처리하고 필요한 물건을 구매하기 위해서이다. 이러한 사용자들의 관점에서 보았을 때, 필요한 물건을 얻기까지의 과정이 장시간 걸린다는 단점이 있으며, 사람들이 필요 없는 물건을 버려 낭비되고 과소비되는 경우도 있다. 이러한 문제를 해결해서 필요 없는 물건을 필요로 하는 사람과 물물교환을 하여 불필요한 소비를 줄이고 필요한 제품을 서로 쉽게 찾고 교환할 수 있도록 사용자에게 편의성을 제공하는 물물교환 시스템을 제안한다.

The purpose of this study is to describe the technologies necessary to design responsive web with the use of the responsive website based on implementation structure as a prototype. Responsive design means the process of analyzing prototype requirements on the basis of implementation and applying the analysis results to development. The design method based on the principle of priority in development was established, and then flexibility and variability through design formula were set up. After that, the user-oriented primary principle and secondary principle were drawn to establish implementation structure. In the way of discussing compression technologies, a method of combination was searched for, and then a method of asynchronous script scalability in line with a web prototype was found. Today, a website or a web application needs to be adopted and accessed regardless of device types. As a solution, a responsive website design method was found. Important technologies for the implementation structure for the responsive website design method and its relevant prototype website were came up with.

The web environment is evolving rapidly. Testing in the web based software is an essential process to improve stability and productivity. Testing of complex web contents and ill(user interface) is most important thing. Implemented test cases are efficient when they are automated and reusable. But, most of the testing automation tools are focused on technical accessibility and functions still. A collaboration of the persons concerned and reusability of implemented test case are ignored. In this paper we propose an efficient way to design automated test case in web environment, and to share and pattern automated test cases we introduce testing framework called NTAF(NHN Test Automation Framework.). The NTAF is based on open source framework. It provides integrated testing environment that web testing cane be automated and managed continuously.

One shot tasks like a MERSC handling policy, a cinema poster, and so on are too small, diverse, and sporadic to make them as apps or web applications. They are usually shared as the form of notes attached in the field or messages in smart phones. In order to support inter-operability with internet web sites, QR/NFC tags are attached to them. What matters in the web technology is that HTML5 standard does not supply the accessability of smart phones' resources like a camera, an audio, magnetic sensors, and etc. In this paper, we propose a universal smart phone application for handling various one-shot tasks in the same UI/UX. One-shot tasks are described with HTML5 web documents, and the URL for the web documents are stored in QR/NFC tags. A smart phone scans a tag, and then the web document is retrieved and presented finally. QR tags can be delivered to other smart phones through messages or SNS. We solve the problem of HTML5 standard supplying a resource access library with javascrippts. We suggested the whole architecture and the internal structure of QR/NFC tags. We show that our scheme is applicable to make variable one-shot tasks.

Because the existing Skemp's play activities learning has only been done on the offline, the hassles of learning paper production, the understanding of achievement levels, and the difficulty of feedback and compensation have been pointed out as a serious problem. Therefore, the aim of this study is to develop web-based learning tool applied the Skemp's play activities for elementary school students who learn mathematical skills easily in the web environment. To demonstrate the effectiveness of implemented web-based learning tool, we have analyzed questionnaire survey conducted for academic achievement of the third grade elementary school students. The analysis results show that for improving the ability of multiplication and division operation, the learning using web-based tool applied the Skemp's play activities is more effective than the learning based on the existing educational process and the result is statistically significant at the 5% significance level.

User interface technology due to the user interface to manipulate the menu system is changing technology. Recently a user interface for the convenience of users at home and abroad for the study is underway. In this paper, we study the model-based interface technology, which is fundamental to develop UI for the user's convenience. For this we study the verification process by analyzing elements of the user interface technology, analyzing the standards of the UI, and finding requirements for the model-based user interface model. This will be used in order to secure the technology for web-application measures and to apply next-generation web-application.

In this paper, we propose a implementation plan of the human resource pool recruitment system using private (permitted) blockchain. The term Human Resource has become commonly used and has come to recognize human resources as resources. Despite these changes, the use of human resource pools has been sluggish. Once entered, information is often not updated on a regular basis and does not provide sharing, searching, carrier management and anti-counterfeiting. In this research, in order to provide a human resource pool recruitment system that utilizes private (permitted) blockchain, we first used the blockchain network to enable sharing and searching of human resource pools, and to use keywords. Used to get results that meet certain conditions. Second, we added an institutional verification process to ensure the integrity of the input data and prepared preventive measures in the non-technical part by utilizing the structural characteristics of the blockchain to prevent counterfeiting and alteration. Third, we designed and implemented a Dapp (Decentralized application) that includes a Web UI so that each of the three groups can control the blockchain and the predefined processes and business logic.
