  • Each ADS must have a validation and evaluation scenario for ODD. This requires a large number of scenarios, so a scenario library must be developed. In order to effectively utilize the scenario library, a system that supports testing in the ODD of the user's choice is required. In other words, in order to develop a scenario library, it is necessary to build a database on actual driving road conditions (geometry, etc.). Accordingly, in this study, we establish a domestic driving environment database based on HD-Map for driving safety testing, design a system that can search test target sections in connection with the ODD of the scenario, and present the implementation results. In the future, it is expected that the domestic driving environment database will be able to create scenarios through linking with the scenario library and directly utilize them for scenario-based evaluation of various demand sources.

  • Purpose: This study was aimed to construct an algorithm of dyspnea emergency care and develop a simulation scenario for emergency care of dyspnea based on the algorithm. Methods: The first stage of this methodological study was to construct a preliminary algorithm based on a literature review, and content and clinical validity were established. Reflecting the result of content and clinical validity for this preliminary algorithm, simulation scenario was developed based on the modified Bay Area Simulation Collaborative scenario template. The content validity of this scenario was established, and clinical applicability was tested by applying this scenario to nurses. Results: The final simulation scenario of emergency care of dyspnea consisted of scenario overview, curricular integrity, and scenario script. The scenario was proceeded on 7 phases of the algorithm as follows; initial assessment, immediate emergency care, reassessment of dyspnea, monitoring respiratory failure, checking pulse if respiratory failure occurs, decision making on cardiopulmonary resuscitation or intubation, determining a differential diagnosis according to origin of dyspnea. Conclusion: The simulation scenario of emergency care of dyspnea developed in this study may provide a strategy of simulation education for emergency care of dyspnea for nurses.

  • 시나리오 기반 학습과 관련하여 학습 관련 효과에 관한 많은 연구들이 집중되고 있다. 그렇지만, 이와 관련하여 바람직한 효과 측정 방법이 제시되지 못하고 있다. 본 연구는 시나리오 학습과 관련하여 보다 바람직한 학습 효과 측정을 위해 하나의 퍼지 논리 기반 프레임워크를 제안하는데 있다. 이러한 프레임워크의 사용은 학습 효과의 측정에 있어서 언어적인 불확실성 문제를 해결할 수 있다. 본 연구에서는 시나리오 기반 학습의 효과 측정을 위해 정확성, 이해성, 완비성의 3가지 불확실성 측도를 사용한다. 이러한 측도의 사용은 시나리오 맥락 측면에서 완전성뿐만 아니라 사용자 선택에 따른 효과 차이를 최소화시킬 수 있는 강점을 가진다. 다른 무엇보다도 시나리오 기반의 학습에 퍼지 논리의 적용은 실제 학습 상황에서 학습 목표 도달을 위한 학습 경로 진행 상황을 쉽게 관측할 수 있다.

  • Recently environmental problem becomes such a big issue all over the world that the necessity and importance of the environmental education in school has been simultaneously emphasized. While diverse methods for the environmental education have been researched, this paper, especially focused on a teaching-learning model called GBS (Goal-based scenario), aims to provide a new learner-centered approach for the environmental education. For this purpose, this paper first briefly presents two theoretical backgrounds of GBS (i.e., constructivism and Schank's dynamic memory theory), which is followed by specific and concrete strategies and methods of how to apply GBS in class for the teacher. GBS(Goal-Based Scenario) is a learner-centered model in which learners are presented with a reality-based scenario (or task or problem) and go through several stages of 'missions' to get to a final solution of the given scenario. GBS, while completely resonant with other constructivist learning models in terms of learner-centered approaches, is distinctive from others, when it supplies more specific, structured guides of learning, called 'missions', to the students throughout the whole learning process. In a words, GBS ought to be recognized as an unique learner-centered model compromising the contradictory concepts of 'learner control' and 'structure and specifics' in learning environments still without any damage of constructivist learning principles.

  • BIM 과 ICT 기술이 도입됨에 따라 '클라우드 기반 협업 설계 지원 시스템'에 관한 연구가 활발히 진행되고 있으며 이를 지원하기 위한 새로운 사용자 인터페이스가 필요하게 되었다. 사용자 인터페이스를 개발할 때 실제 사용 시나리오를 기반으로 사용 상황을 예상하고 사용자의 요구사항을 반영할 수 있는 시나리오 기반 디자인 기법을 선택하였다. 하지만 기존의 시나리오 기반 디자인 기법은 귀납적인 방식이기 때문에 이를 통해 사용 시나리오를 작성할 경우에는 모든 사용자의 사용 상황에 대한 대응이 현실적으로 어렵다. 이러한 이유로 귀납적 방식이 아닌 체계적으로 시나리오를 작성하고 수정할 수 있는 새로운 시나리오 작성 기법이 필요하다. 본 연구에서는 기존의 방식을 보완한 다중 시나리오 기반의 디자인 기법을 제안하였고 이를 '클라우드 BIM 기반 협업 설계 지원 시스템'의 사용자 인터페이스 개발 과정에 적용하여 사용성을 검증하였다.

  • 게임에서 시나리오는 매우 중요한 요소이다. 그러나 아직까지 게임 시나리오 제작을 위한 범용적인 툴은 개발되어 있지 않다. 이를 해결하기 위해서 게임 시나리오와 일반적인 시나리오의 차이점을 알아보고 시나리오 UCC를 분석하여 게임 시나리오에 적합한 구조를 설계하였다. 또한 OSMU의 적용을 쉽게 하기 위해 XML로 게임 시나리오 구조를 정의 하였다. 정의한 시나리오 구조의 활용 가능성을 확인하기 위하여 시나리오 편집기를 만들어 게임 시나리오를 작성한 후 시나리오 기반 게임 "필온라인"에 적용하였다.

  • 전세계 국가는 21세기 메가 트렌드인 기술 융합(Technology Convergence) 추세에 발 맞춰 정보통신(IT)분야 미래비전 및 전략수립에 몰두하고 있다. 그리고, 자국의 국부 증대 및 신산업 창출을 위해 WWRF (Wireless World Research Forum), AmI (Ambient Intelligence), and mITF (mobile IT Forum)등의 공학적 시나리오를 기반으로 한 연구를 하고 있다. 하지만 국내의 경우 비전연구 및 전략수립에 대한 연구가 초보단계로 미래전략 수립에 능동적으로 대처하기에는 미흡하다는 지적이다. 따라서, 본 논문에서는 시나리오 기법을 활용한 선진국의 공학적인 미래전략연구 사례를 분석하고, 공학적인 시나리오 비전연구 방법을 제시한다.

  • Purpose : The purpose of this study was to develop a scenario and to evaluate the students by simulation-based learning of acute abdominal pain case in an emergency unit. The expert group of simulation developed the scenario based on actual abdominal pain by medical treatment records. Methods : Scenario was developed to evaluate the simMan3G simulation-based learning. The scenario was used in 2013 with ten groups of fourth grade 50 nursing students who voluntarily participated in the simulation class. Results : The nursing students were able to express nursing knowledge, learning attitude and self-efficacy. The simulation-based scenario proved to be very effective to students' skill training. The performance of nursing practice through simulation class made the nursing students more confident with patient care. Conclusion : Simulation-based learning was found to be the most effective curriculum to the nursing students and made the students satisfied and confident. So the simulation-based learning would be helpful to other students including paramedic students and medical school students.

  • This study established risk-based fluoride soil contamination standards according to the Korean Soil Contaminant Risk Assessment Guidelines (SRAG). Ten exposure scenarios were evaluated, broadly categorized into Scenario 1, which used the default parameters from the current SRAG, and Scenario 2, which used the latest exposure factors and bio-concentration factors. Fluoride soil standards corresponding to a total hazard index (HI) of 1.0 were determined for each scenario. For children in agricultural areas, the derived risk-based soil fluoride standard was 70 mg/kg for Scenario 1 and 27 mg/kg for Scenario 2. In industrial areas, the risk-based fluoride soil standard was 2200 mg/kg in Scenario 1 and 2300 mg/kg in Scenario 2. This study clearly demonstrated that the crop ingestion exposure pathway exerted predominent influence on the estimated human health risk standards. Additionally, using the Added Risk Approach and considering soil background concentrations, the total fluoride soil standards for residential areas ranged from 232 mg/kg to 444 mg/kg, while the standards for industrial areas ranged from 2405 mg/kg to 2674 mg/kg.

  • Purpose: This purpose of this study was to investigate the effectiveness of educational design according to Goal-based Scenario constituent elements such as educational goals, mission, cover story, role, scenario operation, resources, and feedback in simulation training. Methods: The subjects of this study were 130 nursing students in their senior year who enrolled in the simulation exercise I course. They were divided into a total of 10 groups in which less than 20 students were assigned. In order to verify the effectiveness of the simulation training through Goal-based Scenario instructional design, a design of non-equality control group was carried out. Results: The results of this study were as follows: Critical thinking (t=1.81, p=.073) and problem solving ability (t=1.79, p=.076), course satisfaction (t=8.61, p<.001) and academic performance (t=5.48, p=.001) were supported. Conclusion: This study applied a Goal-based Scenario simulation program to present clear objectives for simulating training and to advance learning methods that are appropriate to the current education environment. In addition, this study has significance in presenting an instructional model for various simulated practice education and can be used as useful basic data related to simulated training education.
