According to the 2021 Mobile Augmented Reality Market Report by Korea Innovation Foundation, the augmented reality market has been growing recently due to the growth of the mobile augmented reality market along with the development of smartphones. In order to provide augmented reality services to mobile users, it is necessary to create native apps for each device. However, there are problems such as maintenance costs for multi-platform and low accessibility due to app download. Recently, the construction of augmented reality system in a web-based environment by using the WebXR Device API is in progress, but it is judged that the system using the WebXR Device API is still in the research stage. In this paper, a responsive multi-platform environment was built using the WebXR Device API, Three JS, and React, and a function to provide augmented reality service to mobile and web users was implemented. As a result of the experiment, it was confirmed that the interlocking of augmented reality was successfully implemented in a responsive web environment, and look forward to the augmented reality service operating on the web in the future.

The Sejong City was launched in July 2012 and was initially focused on the relocation of central administrative agencies, but it has been changing from an administrative city to a fourth industrial city since 2019 to a smart city and the implementation of Korea's New Deal in 2020. Identity design needs to be reevaluated accordingly. In particular, the web environment is also calling for an optimized identity design due to rapid changes in information technology such as various wearables and the Internet of Things. As the number of responsive web sites where information and communication technologies can be developed and optimized screens can be viewed increased, identity was intuitively communicated to users and designs were applied to make them more distinct and empathetic to other cities. Prior to the study, we looked at prior studies on the changing times in the web environment and the reactive web, and analyzed the identity design of the reactive web and applied minimalism characteristics step by step. Based on this, we surveyed experts and non-experts on the proposed survey by applying minimalist characteristics (simple, repeatability, and spatiality) of reactive identity and found that it was easily and intuitively recognizable in a small web environment such as mobile. Therefore, we hope that Sejong City's identity will continue to be studied in various ways and efficient management so that identity can be established in accordance with the changes of the times.

웹 프로그래밍을 공부하는 학생들이 본인들이 만든 웹 페이지를 서버에 호스팅하여 관리하기는 쉽지 않다. 본 논문에서는 스프링 프레임워크를 기반으로 반응형 웹을 개발하고 개발한 웹 페이지를 아마존 웹 호스팅 서비스를 이용하여 호스팅하는 과정을 다룬다. 스프링 프레임워크는 POJO(Plain Old Java Object) 방식의 프레임워크로써 특정한 인터페이스를 구현하거나 상속을 받을 필요가 없어 기존에 존재하는 라이브러리 등을 지원하기에 용이하고 객체가 가벼우며, CSS를 사용한 반응형 웹은 모바일에서도 접근하기 쉬우므로 높은 접근성을 제공한다. 이렇게 개발한 웹 페이지를 호스팅 하여 관리하는 것은 특히 입문단계의 개발자에게 큰 도움이 될 것이다.

In this paper we propose an efficient marker tracking system that exploits IR and web cameras. The proposed method solves the marker swap problem and allows for fast and responsive marker tracking. We use color information gathered from the IR reflector to assign a unique identification to each marker. We can locate each marker withthe IR camera and also identify the marker uniquely by using color information provided by the web camera. The experiment results show that marker swapping can be eliminated effectively. Furthermore, our approach allows for faster and more responsive marker tracking.

A web application running on the Internet is causing many difficulties for a program developer, and it requires to process multiple sessions at the same time due to the occurrence of excessive traffic. Web applications should be able to process concurrent requests efficiently and in real time. Node.js is a single-threaded server-side JavaScript environment implemented in C and C ++ as one of the latest frameworks to implement event models across the entire stack. Nodes implement JavaScript quickly and robust to achieve the best performance using a JavaScript V8 engine developed by Google. In this paper, it will be explained the operation principle of Node.js, which is a lightweight real-time web server that can be implemented in JavaScript for real-time responsive web applications. In addition, this application was practically implemented through automatic alignment system for group scheduling to demonstrate event-based real-time response web processing.

In this paper, we propose an effective web service software platform for remote monitoring and control. In order to propose a system configuration that can check the object information on the web in real time to improve the performance of the web service, the object information reception module and the web viewer system are configured. As IoT devices grow, the environment becomes too complicated to identify and control the status of many devices. We have proposed that these problems be easily controlled in a web-based environment and current status information can be viewed in real time.

In this paper, we propose a testing method of the quality of device application effectively reflecting the necessity of increasing mobile device application quality test, and designed and developed it as a web system. We have studied traditional software testing methods for designing and developing a system. We have developed a next-generation alternative technology that can analyze and compensate for the weaknesses of the web and weaknesses of the Android in order to realize the access system and the responsive web system. As an example applied to the system, we analyzed the requirements of the system implementation and expressed the functions of the system through the use case diagram. The test scenarios were conducted by connecting 5,000 devices to each system using the existing HTTP polling method and the proposed web socket method. After setting the comparative group, the result of the proposed web management system was observed and compared through repeated tests. The research shows that the proposed web socket system has better performance than HTTP polling. The more the number of simultaneous processing of the devices, the lower the server stability but the better the time efficiency. In conclusion, the more the number of devices to be tested is, the more the number of devices can be effectively tested using the proposed web management system.

The Korea Textile and Fashion Industry-Academic Association, which was established in 2004, has been operating without its own homepage until now. In 2019, it was judged that it was urgent to manage new members and build an installed homepage. Therefore, the program provided by 'I'mweb' was used by comparing domestic and overseas website manufacturers, and the reason is as follows. First, 'I'mweb' provides a web builder solution that allows individuals to easily create web sites without IT expertise such as program development, use of photoshop, and coding. Second, it faithfully provides bulletin boards and member management functions necessary in Korea, such as internet homepage builders and shopping mall production services. Third, there is an advantage in that it is easy to manage the homepage because it is convenient to use Q&A service through the administrator when building the web. However, it provides a responsive web function, but it is regrettable that the compatibility between PC and mobile is not smooth. This study is expected to be used as basic data for related research that needs help in opening a website in the future.
