최근 모바일 회의를 통하여 Paperless, 시간적, 공간적 자원을 절약하는 노력들이 진행되고 있다. 그러나 현재 어플리케이션 기반의 모바일 회의 솔루션은 사용자 디바이스의 운영체제에 따라 각각 존재하므로 활용에 제한적이다. 최근에는 HTML5를 이용한 웹 브라우저를 기반으로 모바일 회의를 지원함으로써 모든 디바이스에서 사용가능 하도록 개발하고 있으나 화면 동기화를 위해서는 사용자 디바이스에 어플리케이션을 설치하여야 한다. 본 논문에서는 어플리케이션의 설치 없이도 모든 디바이스에 탑재된 웹 브라우저를 통해 화면 동기화가 가능한 하이브리드 웹 기반의 모바일 회의를 지원하는 양방향 실시간 데이터 미러링 기술을 제안한다.

표준 웹 서비스나 웹 어플리케이션 서버들이 SOAP 메시지를 처리하기 위해서는 웹 서블릿 컨테이너를 필요로 한다. 그러나 이것은 추가적인 통신 포트가 필요하고 웹 서비스 모듈을 직접 구현하여 추가하는 부가적인 작업이 필요로 하는 문제점을 가지고 있다. 또한 최근의 많은 웹 애플리케이션들은 정적인 문서보다 동적인 문서 처리에 대한 요구가 점점 더 커지고 있지만 한 연구 결과에 따르면 아파치 웹 서버의 경우에 동적 문서가 많아질수록 성능이 저하될 수 있다는 것이다. 이러한 문제점을 해결하기 위해서 본 논문에서는 모바일 웹 서비스를 위한 고속 메시지 처리시스템을 설계하고 구현한다. 제안된 모바일 웹 서비스 시스템은 WSDL 변환기와 SOAP_MP로 구성되는 데 WSDL 변환기는 HTML/XML 메시지를 분석하여 WSDL 파일로 자동으로 변환함으로써 시스템 부하를 감소시키고 SOAP_MP는 웹 서블릿 컨테이너를 제거하여 SOAP 메시지를 처리 시간을 최소화한다. 제안된 시스템의 성능평가를 위해서 표준 웹 서비스 시스템과 비교하여 실험 결과를 분석한다.

The damage from voice phishing reaches one trillion won in the past 5 years following report of Business Korea on August 28, 2018. Voice phishing and mobile phone scams are recognized as a top concern not only in Korea but also in over the world in recent years. In this paper, we propose an efficient system to identify the caller and alert or prevent of dangerous to users. Our system includes a mobile application and web server using client and server architecture. The main purpose of this system is to automatically display the information of unidentified callers when a user receives a call or message. A mobile application installs on a mobile phone to automatically get the caller phone number and send it to the server through web services to verify. The web server applies a machine learning to a global phone book with Blacklist and Whitelist to verify the phone number getting from the mobile application and returns the result.

모바일 기기의 보급 및 활용이 급증함에 따라 대학에서도 주요 학생 서비스들을 모바일 기기를 기반으로 제공하고 있다. 이러한 추세에 따라 본 논문에서는 비교적 엄격한 학생 관리가 요구되는 기숙형 고등학교 및 대학 기숙사 업무를 효율적으로 지원하고 관생들에게는 편리한 서비스를 제공하기 위해 모바일 웹 기반의 기숙사 업무 지원 서비스 시스템을 설계 및 구현 하였다. 제안 시스템은 첫째, 업무 관리 측면에서는 모바일 웹 및 전통적인 웹 기반의 관리 환경을 제공하여 점호, 외박 처리 등의 업무 처리 효율성을 높였다. 둘째, 관생 서비스 측면에서 모바일 웹 기반의 환경을 제공하여 웹에 접근 할 수 있는 환경에서는 항시 서비스를 이용할 수 있도록 하여 서비스 수혜자의 만족도를 높였다. 제안 시스템은 250명 규모의 남자 대학생 기숙사를 대상으로 한 학기 동안 운영되었으며 관생을 통한 설문 조사를 통해 그 유용성을 확인하였다.

Purpose: This study aimed to examine engagement and satisfaction with a mobile web-based education program (HiChart) among pregnant women. Methods: A cross-sectional descriptive study was conducted of 97 pregnant women hospitalized for obstetric care. Data were collected from October 1 to November 30, 2016, and were analyzed with descriptive statistics. Results: Among participants, 16.5% engaged fully with HiChart, while 43.3% engaged partially. The overall satisfaction with HiChart was high. Some main reasons for not engaging with the education were participants' unawareness of the text messages, lack of time, and poor internet connection. The participants suggested that more educational content needed to be covered, such as coping with infant emergencies and information about the neonatal intensive care unit. Conclusion: To increase pregnant women's engagement with mobile web-based education, efforts are needed to strengthen the system of sending text messages as part of mobile web-based education to all patients, to inform pregnant women that an educational web link was sent, and to encourage them to engage with mobile web-based education. Furthermore, it is essential to improve the HiChart service by providing educational content corresponding to users' needs.

Autonomous mobile robots based on the Web have been already used in public places such as museums. There are many kinds of problems to be solved because of the limitation of Web and the dynamically changing environment. We present a methodology for intelligent mobile robot that demonstrates a certain degree of autonomy in navigation applications. In this paper, we focus on a mobile robot navigator equipped with neuro-fuzzy controller which perceives the environment, make decisions, and take actions. The neuro-fuzzy controller equipped with collision avoidance behavior and target trace behavior enables the mobile robot to navigate in dynamic environment from the start location to goal location. Most telerobotics system workable on the Web have used standard Internet techniques such as HTTP, CGI and Scripting languages. However, for mobile robot navigations, these tools have significant limitations. In our study, C# and ASP.NET are used for both the client and the server side programs because of their interactivity and quick responsibility. Two kinds of simulations are performed to verify our proposed method. Our approach is verified through computer simulations of collision avoidance and target trace.

Recently, people can create small content by themselves and it improved into a form that can be promoted. Also, as active small business owners increase, they produce the content for promotion by themselves without external professional help and they utilize it. This paper studies the method to make Mobile Apps, Mobile Web and homepage services available by automatically generating the mobile based mini content. The automated content creation system suggests the method that small business owners and groups can easily communicate with new people by bringing Single Page Application, hybrid mobile web app, N-Screen based content building, private cloud-based PaaS building technology, P2P network based file sharing and multimedia thread technologies together and creating the content.

The development of systems that can generate automatically instructional material is a challenging goal for the e-learning community. These systems pave the way towards large scale e-learning deployment as they produce instruction on-demand for users requesting to learn about any topic, anywhere and anytime. However, realizing such systems is possible with the availability of vast repositories of web information in different formats that can be searched, reused and integrated into information-rich environments for interactive learning. This paradigm of learning relieves instructors from the tedious authoring task, making them focusing more on the design and quality of instruction. This paper presents a mobile learning system (Mole) that supports the generation of instructional material in M-Learning (Mobile Learning) contexts, by reusing and integrating heterogeneous hypermedia web resources. Mole uses open hypermedia repositories to build a Learning Web and to generate learning objects including various hypermedia resources that are adapted to the user context. Learning is delivered through a nice graphical user interface allowing the user to navigate conveniently while building their own learning path. A test case scenario illustrating Mole is presented along with a system evaluation which shows that in 90% of the cases Mole was able to generate learning objects that are related to the user query.

Programming tools are essential for students learning numerical analysis. It is troublesome to go to a laboratory where a computer is located after taking a lecture. Nowadays most students have mobile phones which can be used for programming practice through the Internet. PHP is a server-side scripting language designed for web development but also used as a general-purpose programming language. However, PHP has many inconveniences, such as adding a dollar symbol ($) to every varable. This paper introduces a slightly modified language, NAPHP, and a system which is designed for students to use their own mobile phone to write down the language NAPHP and run it on the web page. The system NAPHP-SYS is an educational tool that turns NAPHP into PHP, run PHP code and show the results on the web.
