전세계 인터넷 사용자 수가 약 12억 6천 만명에 이르며 2012년에는 17억명 이상이 인터넷을 사용할 것이라고 추정되는 가운데 웹 데이터베이스 응용에 대한 수요가 비즈니스를 포함하는 모든 분야에서 급속히 증가되고 있다. [1] 그러나 급증하는 수요에 비해 웹 응용의 생성 및 유지·보수는 대부분 수작업에 의존하기 때문에 많은 시간과 노력이 소요되고 있다. 본 논문에서 소개하는 WebAppGen은 ScriptGen과 InteraceGen으로 구성된 웹 응용 자동 생성기로서 웹 응용을 전자동으로 생성해 생산성을 향상시킨다. ScriptGen은 웹 응용에 필요한 폼들과 이 폼들을 통해 이루어지는 질의에 대해 데이터베이스와 연동하여 처리하는 웹 스크립트들을 자동생성하고 InterfaceGen은 ScriptGen을 통해 생성된 폼들을 엮어 접근하기 쉬운 트리 형태의 인터페이스를 제공한다. 상용 웹 응용 생성기들과 달리, WebAppGen은 웹 응용의 전 과정을 자동화 시킴으로써 생산성을 한 단계 더 향상시키고, 생성된 응용은 직관적인 계층구조를 가지는 트리 형태의 인터페이스를 지원한다. WebAppGen이 생성한 응용에서, 한 개의 폼은 관심의 대상인 엔티티 외에 이 엔티티와 직·간접적으로 연관된 모든 엔티티들에 대한 정보를 표현한다. 또한, WebAppGen은 생성될 응용의 기본 틀인 템플릿을 기반으로 하기 때문에 생성된 응용 및 WebAppGen 자체의 유지·보수를 용이하게 한다.

Purpose The mail goal of this study is to find out factors influencing users' satisfaction of public application with the emphasis of service quality of public web and public value. For this purpose, we applied IS success model to develop the research model that explains users's satisfaction and public performance. Design/methodology/approach The proposed research model was developed based on IS success model along with two moderating effects - Service Quality of Public Web and Public Value in order to empirically test proposed causal relationships withing the model. A total of 377 survey responses were analyzed by forming the structural equation modeling with AMOS 24.0. Findings The analysis results show that the service, information, and system quality from IS success model are positively associated with user satisfaction, which in turn is positively associated with public app performance. The results also show that the relationship between user satisfaction and public app performance is positively moderated by public value. However, the relationship between public app service quality and user satisfaction isn't moderated by public web service quality.

The growth of mobile commerce (m-commerce) has been accelerated around the world. Why do e-retailers have to put a great deal of effort for the distribution of their mobile apps? The literature has paid little attention to the influence of the introduction of an e-commerce app on shopping behaviors of consumers. By analyzing the dataset of 2,342 users in Korea, this study aims to broaden our understanding of mobile shopping app usage across competing e-retailers and different channels. We found that a user's prior usage of a specific e-commerce mobile app increases her subsequent usage of its website through a mobile web browser. Thus, mobile apps do not cannibalize the mobile web channel, and there could be a complementary relationship. We also found that a user's usage of competitors' apps is positively associated with her subsequent usage of a specific e-commerce app. Because many consumers search products and compare prices across multiple e-retailers, having a mobile app helps an e-retailer be exposed to more potential consumers. This study is among the first to study the role of mobile apps in e-commerce by showing the dynamics of cross-channel and cross-vendor usage by a user.

The demand for map applications in both Web and mobile environments has been rapidly increased with the population of Web and smart phone usage. Web-based map applications are mostly developed on such environments as ArcGIS and MapServer and mobile map applications are developed on such API levels as Google Maps and Yahoo Maps. But many parts of map applications are still constructed by coding because these environments don't support high level of automation. Our MapAppGen that we have designed and implemented enhances the Web-based map application productivity by generating the map related modules that can be applied to the Drupal that is one of popular content management systems(CMS's). Comparing the applications that are constructed by the Drupal-supported GMap or NodeMap, the applications that are constructed by MapAppGen provide information on not only the interested geographical feature but also its related geographical features. MapAppGen uses Google Maps API and Drupal is a module-based system that supports the creation, composition and management of contents. We are now working on automatic generation of mobile map applications with MapAppGen.

Images in the textbooks influence the learning process. Students often see pictures before reading the text and these pictures can enhance the power of imagination of the students. The findings of some researches show that the images in textbooks can increase students' creativity. However, when learning major subjects, reading a textbook or looking at a picture alone may not be enough to understand the topics and completely realize the concepts. Studies show that viewers remember 95% of a message when watching a video than reading a text. If we can combine textbooks and videos, this teaching method is fantastic. The "TEXT + IMAGE + VIDEO (Animation)" concept could be more beneficial than ordinary ones. We tried to give our solution by using machine learning Image Classification. This paper covers the features, approaches and detailed objectives of our project. For now, we have developed the prototype of this project as a web app and it only works when accessed via smartphone. Once you have accessed the web app through your smartphone, the web app asks for access to use the camera. Suppose you bring your smartphone's camera closer to the picture in the textbook. It will then display the video related to the photo below.

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.
