The Web environment of the frontend domain is increasingly competitive to preempt the new standard of presentation layer. N-Screen, a service that enables users to seamlessly use one content in various devices in Korea, is competing for market preemption by recognizing it as a core service of the future. In the cloud computing, N-screen is a typical service type. However, most of the frontend research required for groupware in enterprise environments has been limited to responsive web design for the web and native apps for mobile. Gradually, the need for MVC design patterns is increasingly widening in enterprise environments to overcome the cultural differences of companies and to support one source multi-use strategy supporting multiple devices and development productivity. Therefore, in this study, we will analyze and design JPetStore with hybrid application design based on Spring MVC, e-government standard framework environment of next generation web standard, and provide reference model of frontend hybrid apps design in future enterprise environment.

By using geolocation and maps, we need to trace the path of ourselves, others, or the objects. Until now, we used a native apps development mehod to develop path tracking systems in mobile devices such as smart phones and tablet computers. A disadvantage of this method is that we have to work again to provide the same service on different platforms. Web Apps and Hybrid Apps are developed to recover this disadvantage. Since Hybrid Apps look like Native Apps apparently, users prefer Hybrid Apps to Web Apps. In this paper, we develop a hybrid app which can trace the path on mobile devices. The recently suggested next generation markup language, HTML5, has geolocation features. By using them, we implemented a hybrid app for a path tracking system. First, we create a web app using HTML5, CSS, and JavaScript, Then, PhoneGap, a mobile development framework, is used to convert it to the hybrid app. By implementing hybrid app, various apps which need path tracking can be developed rapidly and effectively, regardless of the mobile devices.

다양한 크기의 모바일 기기가 등장함에 따라 기존 웹 어플리케이션으로는 개발자가 의도한대로 레이아웃을 구성하기 어려우며 네이티브 어플리케이션은 운영체제별로 각각 개발해야하기 때문에 많은 개발 시간을 필요로 한다는 단점이 있다. 본 논문에서는 부트스트랩을 이용하여 기기의 화면 크기에 가변적인 반응형 웹을 구축하고 모바일 운영체제의 웹뷰를 이용한 하이브리드 앱을 구현함으로써 개발과정 및 개발 시간 단축을 검증하였다.

스마트폰 시장의 급격한 성장으로 기업 업무들이 모바일 환경으로 이전되는 추세와 함께 다양한 모바일 운영체제들의 등장으로 개발 환경의 파편화가 발생하였고 이는 응용 프로그램의 개발 및 유지 보수를 저해하는 요소로 작용하였다. 이러한 문제를 해결하기 위한 모바일 환경의 크로스 플랫폼 기술로 하이브리드 앱이라는 방법론이 제시되었다. 하지만 하이브리드 앱이 가지고 있는 성능적 제약과 기능적 제약으로 시장에서의 주력 기술로 사용되지 못하고 있다. 이러한 단점들을 극복하기 위해 네이티브 환경의 장점을 활용할 수 있도록 하는 범용실행엔진, 자동변환 저작엔진 등의 시도들이 있다. 이 논문에서는 해당 문제를 또 다른 방법으로 접근한 개방형 모바일 클라우드 플랫폼을 소개한다. 모바일 클라우드 환경을 구성하여 모바일 사용자들에게 단말의 하드웨어나 운영체제와는 무관하게 다양한 모바일 환경을 제공할 수 있고 기존 모바일 환경에 비해 고성능의 컴퓨팅을 제공할 수 있게 하는 동작 메커니즘과 기술 특징을 설명한다.

A study on e-book viewer terminal in the native language of the platform-dependent studies are based, This is inefficient in memory usage and screen rendering speed, and there are frequent system updates, e-book viewer, the nature of mobile terminal platform application compatibility issues may occur. In this paper, using the mobile app framework in order to design e-book e-book viewer, analyzed the structure of ePub file parser and file more structured modules were designed and MVC. Designed and implemented to test the functionality of the memory information that is currently running to provide the ability to show the relationship of DDMS and layout components were used to show Hierarchy Viewer. As a result, rendering the screen 150%, 84% in the heap memory usage, improved performance was confirmed.

In addition to direct sales to consumers, the direct-to-consumers (D2C) strategy, which provides specialized experiences and services, communicates closely with a consumer's perspective. This tendency is related to the recent trend wherein the luxury fashion system is being transformed into a new luxury. Therefore, this study analyzes the development of online D2C platforms and investigates the characteristics of new luxury from the functional, symbolic, and experiential dimension perspectives based on mobile apps, which is becoming increasingly important among online D2C platforms. Based on the study results, the premium of new luxury fashion displayed in Louis Vuitton's mobile D2C platform in terms of product utility and functionality is newly defined as a usable luxury experience. Moreover, from the heritage perspective, based on the cultural sympathy of the brand contents, we determine that an attachment can be formed between new luxury fashion consumers and brands. Additionally, the personalization service and experiential content on the D2C platform can directly afford emotional and bonding induced brand immersion in a playful way.

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.

Xamarin is a representative cross-platform development framework that allows developers to write mobile apps in C# for multiple mobile platforms, such as Android, iOS, or Windows Phone. Using Xamarin, mobile app developers can reuse existing C# code and share significant code across multiple platforms, reducing development time and maintenance costs. Meanwhile, malware authors can also use Xamarin to spread malicious apps on more platforms, minimizing the time and cost of malicious app creation. In order to cope with this problem, it is necessary to analyze and detect malware written with Xamarin. However, little studies have been conducted on static analysis methods of the apps written in Xamarin. In this paper, we examine the structure of Android apps written with Xamarin and propose a static analysis technique for the apps. We also demonstrate how to statically reverse-engineer apps that have been transformed using code obfuscation. Because the Android apps written with Xamarin consists of Java bytecode, C# based DLL libraries, and C/C++ based native libraries, we have studied static reverse engineering techniques for these different types of code.

최근 휴대용 기기들이 대중화되어 한사람이 하나 이상의 휴대용 기기를 소지하고 있고 스마트폰 활용도 또한 늘어나는 추세이다. 때문에 폭발적인 스마트폰 응용 활용이 늘어나고 있지만 현재의 애플리케이션 스토어는 각 플랫폼별로 애플리케이션을 개발해줘야 하는 종속적인 면이 있다. 앱스토어는 크게 애플의 앱스토어와 구글의 안드로이드 마켓으로 양분되어 있고 각 플랫폼에 맞춰 애플리케이션이 개발되어야 한다. 각각의 플랫폼에 맞춰서 애플리케이션을 개발하면 비용도 더 들고 다른 소규모 플랫폼(Ex 바다)들은 애플리케이션 개발자들을 끌어 모아야만 자신들의 플랫폼에 맞는 애플리케이션이 나오는 단점이 있다. 각 플랫폼에 맞춰서 개발된 네이티브 애플리케이션의 범용성에 대한 해결책과 모바일에서의 다양한 요구사항을 수용하기 위해 웹 애플리케이션이 각광받고 있다. 웹 애플리케이션은 플랫폼에 종속되지 않고 어느 휴대용 기기에서도 동작하기 때문에 각 플랫폼별로 개발하지 않아도 된다. 따라서 웹 애플리케이션 스토어끼리의 연동 프로토콜을 통하여 애플리케이션들을 어느 웹 애플리케이션 스토어에서도 볼 수 있고 플랫폼에 구애받지 않는 거대한 시장이 생겨날 수 있다. 하지만 아직 웹 애플리케이션 스토어라는 표준이 없고 존재하는 웹 애플리케이션 스토어가 없다. 이를 위해 본 논문에서는 연동에 관한 프로토콜을 제안한다.
