내장형 시스템을 위한 사용자 인터페이스 모델 기반 모바일 웹앱 자동 생성 도구

본 논문에서는 사용자 인터페이스(UI) 모델로부터 모바일 웹앱을 자동으로 생성하는 도구를 제시한다. UI 모델은 UI 중심적인 내장형 시스템을 UI 모델링을 통해 효율적으로 개발하기 위한 방법인 PELUM(Pattern and Event based Logical UI Modeling)을 기반으로 한다. 본 논문에서 제시하는 도구는 모델 편집기와 코드 생성기로 이루어져 있다. 모델 편집기는 웹 상에서 논리적 UI 모델(LUM)과 프로그래밍 인터페이스 모델(PIM)을 모델링하는 환경을 제공한다. 코드 생성기는 LUM을 기반으로 앱의 화면구성 및 이벤트 동작을 설정하고 PIM을 기반으로 로컬 데이터베이스 스키마를 자동으로 구성하여 모바일 웹앱을 생성한다. 또한 PIM에서 외부 혹은 open API 주소를 입력 받아 매쉬업 웹앱을 생성하는 기능도 제공한다. 생성된 모바일 웹앱은 사용자가 손쉽게 최적화할 수 있도록 Model-View-Controller(MVC) 아키텍처로 구현하였다. 이를 통해 사용자는 웹 상에서 UI를 모델링하여 여러 기기에서 동작 가능한 모바일 웹앱을 생성할 수 있다. This paper presents a tool that automatically generates mobile web applications from user interface (UI) models which are based on PELUM (Pattern and Event based Logical User Interface Modeling). PELUM is a method for the effective development of UI-centered embedded systems via UI modeling. The proposed tool consists of a model editor and a code generator. The former provides an environment for modeling a Logical UI Model (LUM) and a Programming Interface Model (PIM) on the web. On the other hand, the code generator sets the screen configuration and events’ behavior, according to the LUM, synthesizing a local database schema according to the PIM, and then generates an executable mobile web app. It also can produce mashup web apps by receiving an open API address via the PIM. The generated mobile web apps follow the Model-View-Controller (MVC) architecture in order for users to easily customize them. The proposed tool enables them to generate mobile web apps that can be executed on various devices by modeling logical UIs on the web.

The humans are under attack involving the hazardous environment and pathogen/biotoxin aerosol that is realistic concerned. A portable, fast, reliable, and cheap Pathogen and Biotoxin Aerosol threat Detection(PBAD) trigger is an important technology for detect-to-protect and detect-to-treat system because the man-made biological terror is a fast and lethal infection. The ultraviolet C(UVC) wavelengths light source is key issue for PBAD that is sensitive because of strong fluorescence cross section from fluorescent amino acids in proteins such as tryptophan and tyrosine. The UVC-light emitting diode(LED) is emerging light source technology as alternative to laser or lamps as they offer several advantages. This paper discussed about the design consideration of UVC-LED for the PBAD system. The UVC-LED and PBAD technology, currently available or in development, are also discussed.

In this study, we domestically developed a smoke remote sensing device of open-path light transmission type that can remotely measure the smoke concentration generated from an in-use diesel vehicle. The developed analyzer adopts a multi-channel optical path type by a light source of sufficient power and beam splitters, which can be used versatilely regardless of vehicle model. Measurement accuracy was secured through high performance optical sensors and signal stabilization. The laboratory test results of the developed analyzer show a sufficient correlation with the reference analyzer (r²=0.586), which is comparable to the performance of a benchmarked foreign analyzer. However, as a result of the field test, the correlation coefficient was as low as 0.320 on flat road conditions and 0.125 on slope road conditions, and the correlation was lower on a smoke-rich condition. Thus, additional performance improvement is required to be widely utilized in the in-use vehicle management policy of the Ministry of Environment.
