Recently, as the uncontact service is activated in earnest due to the Corona 19 virus, the necessity of system development to provide non-face-to-face contact remote medical service has increased. In this study, we propose a smart healthcare system, Rm_She(Remote Medical Smart Healthcare System). Rm_She can collect and manage various vital signs information by connecting various healthcare products that detect bio-signals based on IoT to one application. The health check app (HC_app) is used to connect vital sign measurement devices to a wireless LAN and receive vital sign values from the HC_app. Then, the vital signs are output to the user on the smartphone, and the corresponding information is transmitted to the healthcare management server. The healthcare server receives the measured values and stores them in a database, and the stored measured values are provided as a web service so that medical staff can remotely monitor them in real time.

Because of rapid spread of the PC, many users have been enjoying a variety of content as PC. Especially in recent years, young people has increased dramatically PC usage. Young people get more easily information using a PC. Especially they relieve their stress through online games and feel another fun of virtual reality. It is obviously a good effect that they contact IT culture with rapidly developed. But young people's perspective with world is narrow because of doing more indoor activities than outdoor. Therefore we built Spot experience voucher system using smart phone application. We hope that many young people act outdoor activities. And Our product offer hybrid device by developing HTML5-based app. Thus this app will give interest of spot-experience to young-people. So If young people use this app, they can have many experience and see diverse aspects.

As the distribution rate of a smart phone which can actualize even augmented reality is getting higher, the application scope of a smart phone is sharply increasing. However, in spite of various functions of it, there is still lack of learning app. Mobile equipments can bring no spatial-temporal restriction of learning to a learner, but they can tempt a learner into inappropriate spaces. In this sense, learning app is necessarily needed to motivate and keep learner's inner desire. This thesis suggested considerations when learning mobile app is designed by analyzing motivation strategy of ARCS Theory and UI of web based contents. Also, a design method of mobile learning app was suggested based on a procedural model of mobile learning app adapting ARCS Theory.

The necessity of shipping market information services has been on the rise which emphasizes the relevance of transaction information and market information to parties both in and outside the shipping industry. However, previous related researches have been restricted to explorations limited by the offerings of existing shipping market information providers. Users today require effective information, an efficient contents management system, interfacing to help the information provider, graphing and spread sheets to facilitate and present the analyzed information through diverse formats, and reliable web and mobile services to provide information effectively with limited human resources. As a first step, service information has to be defined, so that it takes into account user utility, information retrieval and data development. Second, benchmark information and services must be provided from leading shipbrokers and research institutes. Third, a review of the latest technical trends is required to identify the most suitable technologies for servicing shipping market information. Finally, analysis is required on the implementation of a system with selected technologies, as well as the development of channels to post information which have been analyzed by users. Such a process would enable the continual redefinition of the shipping market information users actively need. The application of an X-Internet based WCMS, with a single-window dashboard providing user-customized information, and used to obtain and manage processes, add spread sheets to sustain calculations using the latest information, graph results, and to input additional information following predefined rules. Access to data and use of the system would require agreement that the system will incorporate user data and user-analyzed information into the market report, web portal, and hybrid app to provide current shipping market information appropriately and accurately to service users.

The group is one of the hobbies and other life groups, and each person in the group directly attends the meeting and works on the topic of the group. In this paper, we implemented voting, announcements, surveys, and suggestions, which are necessary functions for similar groups including group. We also provide web sites based on Apache web server for convenience of Android smartphone applications, OS except Android, Group management can be managed by using the manager's website which can manage the whole group management. It is designed with Apache web server, web communication language PHP, MySQL database, and Android.

Recently, the emergence of a variety of devices to be able to access web have brought many technological changes in the field of web development. However some web sites are still operating with a focus on computers, especially exclusive and slow developing job training related web sites which utilize a User Interface that targets only PCs. In this paper, we propose the job training management system which has a menu configuration and functions to be applied to a variety of devices, and also an applicable technologies for training students to access more easily. Finally, we evaluated its efficiency by applying the implemented system in the actual field.

We forecast that the scale of mobile market will be large scale according to the twenty million times of smart phone's user is arrived. The type of software development is being transferred into mobile-based App. or cloud computing-based service from web-based software. Currently both Google's android and Apple's IOS are known for two prominent platforms. Existing modeling techniques cannot be applied into the case of mobile application which is executed those platforms. Therefore, we suggest a modeling technique that is customized existing modeling techniques into android-based software development. That is, we propose an analysis and design techniques which are needed into android-based mobile smart environment.

In this paper, in order to improve the execution performance and serviceability of cross-platform applications frameworks based on the existing web applications, we design and implement a new hybrid application framework named as WApplE.js, which enables direct control of native UI(User Interface) of mobile operating systems and various resources via JavaScript. We first present the design results for the overall software structure and the configuration of every layer of WApplE.js, and then analyze the processes for calling and handling APIs in the implemented hybrid application framework. In addition, the results of comparison of features to the existing frameworks are presented.

Until the 4th Industrial Revolution fused the Web with diverse technologies, the only factor in evaluating the performance of a Web application was the loading speed of the Web application. Therefore, most existing Web application performance analysis tools focus on the speed at which Web applications run in a Web browser. However, the web is now being used not only in a simple web browser but also in a variety of services. So, in addition to simple speed, there are more elements to be checked to evaluate web applications. Therefore, in this paper, we design a server to perform web application performance analysis considering progressive web app, accessibility, best practice, and search engine optimization as well as the above mentioned speed. Also, we realize a REST API based server that can provide web application performance services without being affected by user's devices or environment.

사물인터넷(Internet of Things)의 도래와 함께, 무선공유기(wireless access point)들의 보안이 심각한 문제로 대두되고 있다. 연구진은 대부분의 무선공유기들이 제공하는 웹 기반 관리 인터페이스들에 웹 어플리케이션 취약점(web application vulnerability)들이 존재할 수 있다는 점을 착안, 국내 주요 무선공유기들에 대한 웹 어플리케이션 취약점 점검을 수행하였으며, 악용이 가능한 여러 취약점들이 존재함을 확인하였다. 본 논문에서는 연구진이 무선공유기 대상 웹 어플리케이션 취약점 점검에 보조적으로 사용하기 위하여 개발한 3종의 모바일 앱(mobile app)들을 설명한다.
