Purpose: The purpose of this study was to develop a scenario and evaluate students' performance in simulation learning of care for patients with asthma in emergency units. Methods: Meetings of experts were used to develop a scenario based on actual patients and textbook material. An evaluation protocol was developed to evaluate the simulation learning. The scenario was used in 2006 with six groups of 26 senior nursing students who participated voluntarily. Results: The scenario was developed according to the nursing process for 15 minutes of simulation learning. The nursing students were able to demonstrate their knowledge and skills. The results showed a need to improve problem solving ability. In the self-evaluation, the students reported that simulation learning helped them to integrate their knowledge to practice and recognize their weaknesses and strengths. However, the scores for self-confidence about patient care after the simulation learning were low (4.8/10). Conclusion: The scenario in this study gave the students the experience of providing qualified and secure nursing care under conditions similar to reality. Further development of a variety of scenarios for simulation learning is needed.

Purpose: The purpose of this study was to develop a scenario and evaluate the performance of paramedic students in head trauma simulation education. Method: This study selected a refined head trauma scenario that was developed by graduate students during class from september to November, 2010. Evaluation on implementation of head trauma simulation was conducted on seventeen paramedic students divided into four groups during November, 2010. Results: 1. The head trauma scenario was developed according to the patient assessment for approximately 10 minutes. It contained scene size-up, initial assessment and intervention, rapid trauma assessment and intervention, and decision of transfer. 2. The average time turned out to be 9 min and 36 sec after simulation learning. Total mean score in simulation performance was 2.20, the highest score was 2.44 in initial assessment and intervention, and the lowest score was 1.5 in decision of transfer. 3. Confidence mean was high with the score of 1.0. Conclusion: The finding of this study demonstrate that the simulation education can improve problem-solving ability and critical thinking, and increase the confidence in prehospital emergency care; therefore, simulation may be the new effective paramedic education strategy and simulation learning is needed for further development of various scenarios.

The Material Transportation Capability Analysis Method in North Korea includes adversary's activities such as destruction of bridge which is one kind of choke points in the road network and surprise attack against resupply march unit. Also, the amount of damage on choke points in the road network and repair time depending on repair unit commitment must be reflected. In this study, a scenario encompassing plausible resupply transportation circumstances while counterattacking into NK will be established. Then, based on such scenario, a simulation model will be established and the result of simulation will be compared to the results of numeric example which has been used in the ROK Army. We demonstrate, through a certain Corps operation area, that the Scenario-based Simulation Model results predict the performance of resupply operation very well. Therefore, it makes sustainment planners and commanders do activities which is suitable for battlefield and should be used in the real situation. It is also a stochastic model.

Scenario analysis for strategic planning, unlike most forecasting methods, provides a qualitative, contextual description of how the present will evolve into the future. It normally tries to identify a set of possible futures, each of whose occurrence is plausible but not assured. In this paper, we propose the use of Cross Impact Analysis(CIA) approach for scenario generation about the future of Korean IT environments. In this analysis, we classified IT environments into technical, social, legislative, and economic factor. And various variables and events were defined in each factor. From the survey collected from IT related experts, we acquire probability of occurrence and compatibility estimates of every possible pairs of events as input. Then 2 phase analysis is used in order to choice events with high probability of occurrence and generate scenario. Finally, after CIA using Monte Carlo simulation, a detail scenario for 2010 was developed. These scenario drawn from the CIA approach is a result considered by cross impacts of various events.

미래의 무기체계 개발은 점점 복잡해지고, 많은 비용이 소요된다. 무기체계 개발을 위해 M&S(Modeling & simulation)기술을 사용하는 것에 대한 관심이 점점 높아지고 있다. M&S기술은 훈련, 전략 수립, 교전수칙, 무기체계 획득 등을 하는데 활용된다. 본 논문에서는 교전급 모델의 운용을 위해 소규모 교전 시나리오 생성 방안을 제시 한다. 생성된 시나리오는 지휘관의 훈련, 체계 운용 분석, 전술 검증을 위해 사용된다. 이 연구에서는 FSA(Finite State Automata)이론과 DFS(Depth First Search)알고리즘을 이용해 시나리오를 생성하는 방법론을 제시하였다. 그리고 제안된 방법론을 이용해 공격함과 정찰함이 교전하는 소규모 교전 시나리오 예제에 적용하였으며 이를 Delta3D$^{TM}$로 가시화 하였다.

This paper suggests an event-based scenario manager capable of creating and editing a scenario for shipbuilding process simulation based on multibody dynamics. To configure various situation in shipyards and easily connect with multibody dynamics, the proposed method has two main concepts: an Actor and an Action List. The Actor represents the anatomic unit of action in the multibody dynamics and can be connected to a specific component of the dynamics kernel such as the body and joint. The user can make a scenario up by combining the actors. The Action List contains information for arranging and executing the actors. Since the shipbuilding process is a kind of event-based sequence, all simulation models were configured using Discrete EVent System Specification (DEVS) formalism. The proposed method was applied to simulations of various operations in shipyards such as lifting and erection of a block and heavy load lifting operation using multiple cranes.

본 연구는 우리의 임상상황에 맞는 시뮬레이션 학습시나리오를 개발하고 시뮬레이션 학습에서 문제해결력과 학습 만족도를 평가함으로 적용가능성을 검증하고자 하였다. 본 연구의 학습시나리오는 응급실에 내원한 간경화증환자의 고칼륨혈증 사례를 개발하여 간경화증과 관련하여 합병증과 증상에 대한 다양한 상황을 시행해볼 수 있는 내용으로 구성하였다. 시나리오 개발단계는 시뮬레이션 학습 목표 및 시나리오 상황 설정, 알고리즘 작성, 임상수행평가 체크리스트 작성, 디브리핑 준비 순으로 이루어졌고, 시나리오는 Jeffries가 제시한 시뮬레이션 학습시나리오 진행 개요에 따라 모니터 세팅(행동들), 환자/마네킨(행동들), 예상되는 중재(사건), 단서를 시간에 따라 구성하였다. 시나리오는 '임상수행능력평가' 과목에 등록한 53명의 간호 학생을 4-5명씩 그룹화 하여 2011년에 사용되었다. 시뮬레이션 학습 적용 전 후 간호학생의 문제해결력 점수는 학습 전 평균 4.05점에서 학습 후 평균 4.30점으로 통계적으로 유의하게 향상되었고 (t=-3.97, p<.001), 시뮬레이션 학습 적용 후 학생들의 학습만족도는 5점 척도에 평균 4.09점을 나타냈으며, 학생들을 수업의 주체로 이끌어 낸 점은 시뮬레이션을 활용한 수업이 효과적인 간호교육방법이 될 수 있다고 본다.

간호 실무 능력의 개발을 위해서는 임상 환경에서의 지속적인 경험이 중요하지만 간호학생의 임상 경험의 기회는 줄어들었고 모든 학생들이 충분히 임상 경험을 한다는 것은 현실적으로 어렵다. 이러한 문제를 해결할 수 있는 방안으로 시뮬레이션 학습을 생각해 볼 수 있는데, 성인대상의 간호 시나리오 개발이 주로 이루어졌고 아동대상의 시나리오 개발은 거의 없는 실정이여서 아동간호와 관련된 시뮬레이션 시나리오 학습내용을 개발하고자 시도되었다. 시나리오의 내용은 응급실 내원 발열환아 간호과정을 중심으로 구성하였다. 시뮬레이션 학습 시나리오 적용 결과, 학생들은 실습에 대한 자기효능감, 수업태도와 수업에 대한 만족도가 증가하였다. 따라서 더욱 다양한 사례의 아동관련 시뮬레이션 시나리오를 개발하여, 아동간호와 관련된 실제와 유사한 임상 상황들을 학생들에게 적용한다면 아동과 그 가족에 대한 질 높은 간호를 제공할 수 있을 것이다.

일반적으로 네트워크 공격은 단위 공격이 혼합된 시나리오 형태이다. 시나리오 공격은 광범위한 네트워크 환경에서 이루어지기 때문에 공격 범위가 분명하지 않아 공격과 관련 없어 보이는 불분명한 패킷들까지 분석이 요구된다. 이는 공격에 무관한 패킷들까지 분석에 가담시켜 공격 패턴 탐지를 보다 어렵게 하는 요인이다. 본 논문은 시나리오를 갖는 공격에서 공격에 관련된 패킷 분류를 돕는 공격 시나리오 시뮬레이션 시스템을 설계하고 구현한다. 제안된 시스템은 분석대상 네트워크를 시뮬레이터의 가상환경으로 복제하고, 시나리오에 기반을 둔 공격 행위가 포함된 TCPDUMP패킷을 복제된 가상환경에서 시뮬레이션 할 수 있다. 이 시스템은 보안 관리자들이 공격 시나리오 패턴분석에 유용하게 활용할 수 있을 것이다.

In defense domain, mission level and engagement level simulation tools exist. In order to experiment a simulation scenario for obtaining results of both mission level and engagement level simulations, we should write a same simulation scenario in a mission level simulation tool as well as an engagement level simulation tool, and we have to operate these tools for analysis of each purpose. Moreover, we could not guarantee that these scenarios are completely same since each scenario is composed of different fidelities of simulation models, although the scenarios are written by a same experimenter and with same simulation purpose. To deal with the difficulties, I propose an approach to analysis of both mission level and engagement level simulations from one simulation result. For this, I have built Composite Combat Mission Planning Simulation Environment (CCMPSE). In this paper, the HLA/RTI based simulation composition technology and my experiences for the designed Composite Combat Mission Planning Simulation Control System (CCMPSCS) are explained. Moreover, This paper also conducts a case study with EADSIM, SADM, and the CCMPSCS. Finally, this paper provides lesson learned from the case study.
