본 연구는 최근 국립공원을 찾는 사람들이 많아짐에 따라 국립공원 관리의 정책 방향을 검토·결정하는데 필요한 국립공원 이용·보전 관리에 대한 시민의 여론을 확인하고자 진행하였다. 지금까지 국립공원 이용 및 인식과 관련한 설문 조사, 빅데이터 분석 등이 수행됐으나 공원 관리의 쟁점 사항 및 이용에 관한 조사 문항 등이 부족하며 조사 대상이 탐방객으로 국한되는 등의 한계가 있었다. 따라서 시민들의 국립공원 이용과 현재 운영되고 있는 제도에 대한 인식을 확인하기 위해 일반 시민을 대상으로 설문 조사를 진행하였다. 연구결과 탐방객을 상대로 진행된 선행연구들과는 달리 일반 시민들은 고지대 탐방보다는 저지대 탐방을 선호하는 결과가 나타났다. 또한 국립공원에서는 산정부 탐방 금지 정책에 대해 일반 시민들은 현재의 정책을 유지하거나 탐방예약제를 소폭 도입하는 것을 선호하는 것으로 나타났다. 그리고 탐방예약제를 이용해본 시민들의 비율도 매우 적은 것으로 나타났다. 도출된 결과를 바탕으로 탐방객과 일반 시민의 차이점을 고찰하고 공원 관리 원칙과 방향성의 변화, 국민의식과 탐방형태의 변화에 따른 정책여건을 전망하였다. This study investigated the public opinion on the use and conservation management of national park, to manage the growing demand of national park visit and to support the policy direction of national park. So far, various surveys and big data analysis on the use and perception of national park have been conducted, but there have been limitations such as lack of survey questions on issues in park management and use. In addition, the object of the previous studies were limited to the national park visitors; therefore, this study expanded the object of survey from national park visitors to ordinary citizens. Unlike previous studies conducted only on national park visitors, ordinary citizens relatively prefered bottom areas rather than high-altitude ones. A policy to limit the visit to high-ridge area of mountain is being currently driven; however, the survey results of ordinary citizens suggested to maintain current policies or to increase visitor reservations system within narrow limits. On the other hand, the proportion of citizens who have used the visitor-reservation system was very small. We discuss the difference between national park visitors and ordinary citizens and the policy conditions according to changes in park management principles and public attitudes toward national parks.

AUTOSAR(AUTomotive Open System ARchitecture) is established an open standard for automotive electric/electronic architecture. It will serve as a basic infrastructure for the management of functions within both future applications and standard software modules. The software based on AUTOSAR standard has flexibility, scalability and improved quality. In this paper, we analyze the specifications of AUTOSAR authoring tools and present a development method for the tools.

Recently a standard software platform for automotive, AUTOSAR, has been developed to manage growing software complexity and improve software reuseability. However reuse of testing system and test data are difficult because they are dependant on implementation language and testing phases. In this paper, we suggest a automated testing approach for AUTOSAR software component using a standardized testing language, TTCN-3. AUTOSAR defines the AUTOSAR XML Schema for the data exchange format so that it is possible to automatically convert AUTOSAR model into TTCN-3 testing model. Therefore our approach is to present generation techniques for the TTCN-3 testing system from a AUTOSAR XML description. With the proposed testing techniques we can reduce time and effort to build the testing system and reuse testing environment.

Automotive systems have tended to be equipped with many electronic contents to satisfy safety, comport, convenience, and entertainment services over the past years. As a result, the amount of vehicle embedded software in electrical/electronic(E/E) systems is steadily increasing to manage these requirements. This leads to the traditional, document-based software development in the vehicle embedded systems being increasingly displaced by a model-based development in order to reduce software development time and cost. Due to the application of model-based development, a great evolution is being realized in the aspect of efficiency, but the development is being made without sufficient testing. So, erroneous automotive embedded software may cause serious problems such as car accidents which relate to human safety. Therefore, efficient methods for model-based test and validation are needed to improve software reliability in the stage of embedded software development. This paper presents the model-based development and test method for AUTOSAR embedded software to improve its reliability and safety, and it is demonstrated based on the case study.

최근 차량 소프트웨어의 신뢰성 및 재사용성 향상을 위하여 AUTOSAR 표준을 제정하였다. 그러나 소프트웨어의 표준화만으로는 높은 수준의 신뢰성 확보와 개발기간 단축에 한계가 있으며, 소프트웨어 테스팅 표준화 및 자동화가 필요하다. 본 연구에서는 TTCN-3 테스트 표준을 적용한 AUTOSAR 소프트웨어 컴포넌트를 위한 테스트 자동화 방법 및 테스트 시스템을 제안하였다. 테스트 표준을 적용함으로써 테스트에 관련된 정보 교환 및 의사소통이 명확해 지고, 테스트 재사용성을 향상시킬 수 있다. 그리고 설계 모델로부터 테스팅 모델을 자동 생성함으로써 개발 기간 단축 및 신뢰성을 향상시킬 수 있다. AUTOSAR, a standard software platform for automotive, has been developed to manage software complexity and improve software reuseability. However reuse of test system is difficult because it is dependant on implementation language and test phase. In this paper, we suggest a test system generation method for AUTOSAR software component using TTCN-3, a standardized testing language. TTCN-3 test system is generated automatically from AUTOSAR XML containing software design information. The test system consists of TTCN-3 tester and target system and tests functionality and worst case response time of software under simulation environment. With the proposed testing techniques we can reduce time and effort to build the testing system and reuse testing environment.

This paper presents an application software design and a simulation environment implementation, based on AUTOSAR software platform, for electric power steering (EPS) system. A software architecture with applicable control logics is proposed in conformity with AUTOSAR standard document. In addition, a design of tasks and runnables along with the architecture are developed, which consist of application software, in this paper. Furthermore, a software in the loop(SIL) simulation test bed, using Matlab and CANoe tools, is implemented to validate the proposed EPS development processes.
