Currently workflows in business processes and distributed computing environments have provided service automation by connecting many tasks with rules and/or orderings. The services in ubiquitous computing environments have to automatically provide users with adaptive services according to dynamically changing contort information, which is obtained from both the users and their environment. To adapt these workflows to ubiquitous computing, we must specify the situation information on the transition conditions. In this paper, we propose uWDL, Ubiquitous Workflow Description Language, based on Web Services to use the situation information on the transition constraints of workflow's services. uWDL can select adaptive services according to contexts, profiles, and events information, which are situation information. Furthermore, we verified the execution of a scenario document described with uWDL using the parser and the context handler for uWDL. The scenario developers can use the uWDL scenario editor for a design of scenarios, and they can easily specify the transition condition of the services according the situation information of ubiquitous environments using the uWDL.

With the introduction of BIM and ICT technology, 'Cloud-based collaborative design support system' has been actively researched and new user interface is needed to support it. When developing the user interface, scenario - based design method is selected which based on the actual usage scenarios to anticipate the usage situation and reflect the user's requirements. However, since the existing scenario-based design technique is an inductive method, it is difficult to cover the usage situation of all users when creating the usage scenario. For this reason, there is a need for a new scenario creation method that can systematically create and modify scenarios instead of inductive methods. This study proposes a 'Multi-scenario-based design method' that complemented the existing method and verify its usability by applying it to the user interface development process of 'Cloud-based collaborative design support system'.

Recently, various studies have been conducted to improve automated vehicle (AV) safety for AVs commercialization. In particular, the scenario method is directly related to essential safety assessments. However, the existing scenario do not have objectivity and explanability due to lack of data and experts' interventions. Therefore, this paper presents the AVs safety assessment extended scenario using real traffic accident data and vision transformer (ViT), which is explainable artificial intelligence (XAI). The optimal ViT showed 94% accuracy, and the scenario was presented with Attention Map. This work provides a new framework for an AVs safety assessment method to alleviate the lack of existing scenarios.

멀티미디어의 정보 전달 기능과 인상에 의한 교육 기능이 강력함에 따라 많은 멀티미디어 교육용 시스템이 개발되었으나 대부분의 경우 내용이 빈약하거나 시나리오가 고정되어 있어서 다양한 상황을 연출하지 못하고 단편적인 내용 전개에만 그치고 있으며 학생의 참여가 미흡한 일방적인 지식 전달에 머무르고 있는 설정이다. 이것은 멀티미디어 데이터는 많으나 데이터를 상연할 시나리오가 제작자의 의도대로만 전개되고 사용자의 행동에 따라 다양한 상황으로 전개할 수 있는 여건이 마련되지 않았기 때문이다. 따라서 본 논문에서는 데이터베이스와 멀티미디어 스크립트를 이용하여 필요한 데이터만 갖추어진 제작자의 창의력에 따라 다양한 교육 내용을 저작할 수 있고, 실행 중에 사용자가 다른 상황으로 전개할 수 있는 스크립트와 시뮬레이터를 제안한다.

본 논문은 감시정찰 센서네트워크 환경에서 초소형 복합센서를 이용하여 적 또는 전장 환경에 대한 감시정찰 업무를 수행하는 무인 감시정찰 기술을 기반으로 한다. 감시 정찰 환경에서 센서를 통해 획득하는 환경 평가로서, 적군의 도보를 통한 침투 및 차량의 이동을 파악하고 경로를 도시하여 적군의 이동이나 작전 상황을 평가한다. 본 논문은 이러한 감시정찰 시나리오에 따른 상황을 추출하고, 해당 시나리오를 바탕으로 상황을 평가하기 위한 지능형 에이전트의 구조 및 설계 메커니즘을 제안하여 보다 효율적인 감시정찰 운용 및 수행을 위한 기반 기술로 활용한다.

본 논문은 제조 산업 현장에서의 업무 능력 향상을 위한 XR 교육훈련 콘텐츠의 가변적 시나리오를 제안한다. 가변적 시나리오를 적용한 XR 교육훈련 콘텐츠는 교육훈련 관리자가 자유롭게 시나리오를 가감할 수 있어 동일한 콘텐츠 내에서 다양한 시나리오로 콘텐츠를 구성할 수 있는 특징을 가진다. 이는 기존 하나의 시나리오로 반복되는 교육훈련의 한계를 해결할 수 있으며, 현장에서 발생할 수 있는 돌발적 상황 및 변화되는 업무 프로세스를 효과적으로 진행할 수 있을 것이다.

The many researches on context-aware service based on the combination of semantic technology and IoT environment are being actively done. However, the previous study exploiting ontology has limitations not to accommodate the service requirement changes due to ontology prebuilt by specific service scenario. Although the concept of cross vertical ontology has emerged in order to overcome the limitation, it has other limitations that need additional components composing service environment for expressing context information and can't represent state information of environment elements. To cope with these limitations, we propose SISO (Semantic-based IoT Service Ontology) that can represent the states of environmental element without the need for additional context-information element. To verify SISO's characteristics, we select the service scenario and present applied results. The qualitative analysis comparing with the previous study is also presented by the applied results of service scenario.

Since emergency response training for maritime safety and safety education of maritime education institutions are conducted based on the set scenarios and education contents, there are limitations in the reduction of human error and response to various situations. Although there is a need for improvement, there is no way to improve response capabilities by assessing existing education training and securing diversity in situations. This study proposes a theoretical procedure analyzer method to model the diversity of situations for the improvement of emergency response training. This paper defines the human and system theoretical procedure analysis model (HSTPA) based on the organic relationship of the source and system. The limitations of the existing training were derived by analyzing the errors that each component could produce and applying them to the fire response training scenarios requiring vertical reporting systems and responses. The segmentation and inspection of training scenario considerations applying the proposed HSTPA model is believed to help create diverse and realistic scenarios in emergency response training and education, and improve the situation judgment understanding and response capabilities of the subjects.

This study examines the development of content scenarios to facilitate the training of on-site commanders in firefighting activities. To establish the training content scenario system, the three core competencies of the on-site commanders were set as situation judgment, communication, and decision-making. A system of scenarios was established to actively reflect these three core competencies when designing the scenarios. All the contents of these scenarios are based on Standard Operating Procedures (SOP). The scenarios comprise 14 stages that are divided into four steps with the exception of stages 1 and 14, which mark the beginning and end of the training. It consists of the situation setting stage and the first, second, and third decision-making stages. Specifically, situation judgment and communication are important factors in each stage.
