The empirical Green’s function method is applied to the foreshock and the mainshock of the 2016 Gyeongju earthquake to simulate strong ground motions of the mainshock and scenario earthquake at seismic stations of seven metropolises in South Korea, respectively. To identify the applicability of the method in advance, the mainshock is simulated, assuming the foreshock as the empirical Green’s function. As a result of the simulation, the overall shape, the amplitude of PGA, and the duration and response spectra of the simulated seismic waveforms are similar with those of the observed seismic waveforms. Based on this result, a scenario earthquake on the causative fault of Gyeongju earthquake with a moment magnitude 6.5 is simulated, assuming that the mainshock serves as the empirical Green’s function. As a result, the amplitude of PGA and the duration of simulated seismic waveforms are significantly increased and extended, and the spectral amplitude of the low frequency band is relatively increased compared with that of the high frequency band. If the empirical Green’s function method is applied to several recent well-recorded moderate earthquakes, the simulated seismic waveforms can be used as not only input data for developing ground motion prediction equations, but also input data for creating the design response spectra of major facilities in South Korea.

본 연구는 간호 대학생을 대상으로 시나리오를 통한 건강사정 실습교육이 의사소통 능력, 비판적 사고 성향 및 학업성취에 미치는 효과를 보기 위한 비동등성 대조군 사전-사후 설계의 유사실험 연구이다. C북도 G군 소재 J대학교와 G도 P시 소재 P대학교에서 건강사정 교과목을 수강하는 간호학과 2학년 학생을 대상으로 실험군 35명, 대조군 34명에게 각각 시나리오를 통한 실습교육과 전통적 실습교육 수행 전ㆍ후로 자료를 수집하였다. 연구결과, 시나리오를 통한 건강사정 실습교육을 받은 실험군이 전통적 실습 교육을 받은 대조군보다 의사소통 능력(t=2,797, p=.007), 비판적 사고 성향(t=2,406, p=.019), 정보수집능력(t=2,977, p=.004), 문제인식능력(t=3.584, p=.001)이 통계적으로 유의미하게 높아졌다. 그러므로 간호 학생들의 의사소통 능력, 비판적 사고 성향, 정보수집능력 및 문제인식능력 향상을 위해 건강사정 수업 시 시나리오를 통한 실습교육프로그램을 활용할 수 있을 것으로 생각된다.

Purpose: This study was conducted to explore Virtual Reality (VR) utilization strategies in scenario-based nursing simulation training. Method: This was an integrative review for the identification of scenario-based VR simulation training applied to nursing undergraduates. The existing literature was searched in electronic databases using RISS, PubMed, and Pro-Quest and the key words were “Scenario based,” “Simulation,” “Virtual reality,” “Virtual training,” and “Nursing.” Finally, five studies were analyzed. Results: All the studies were conducted from 2016 to 2019. One RCT, two quasi-experimental studies, and two mixed method studies were identified. The topics of the scenarios were all different; acute myocardial infarction, management of respiratory system disease with hypoxia, postoperative nursing with appendicitis, teamwork and communication in outpatient and emergency situations, and disaster situation training . The outcome variables that were significant statistically were performance, self-confidence, and learning satisfaction. Conclusion: The findings suggest that virtual simulation in nursing education can potentially improve knowledge, performance, and learning confidence and can increase satisfaction with learning experience among nursing undergraduates. Multidisciplinary cooperation and investment are needed to develop diverse content applying VR in nursing simulation education. The review of the side effects also needs to be performed.

The paper presents the damage estimation of bridge structures in Daegu city based on the scenario-based earthquakes. Since the fragility curves for domestic bridge strucures are limited, the Hazus methodology is employed to derive the fragility curves and estimate the damage. A total of four earthuquake scenarios near Daegu city are assumed and structure damage is investigated for 81 bridge structures. The seismic fragility function and damage level of each bridge had adopted from the analytical method in HAZUS and then, the damage probability using seismic fragility function for each bridge was evaluated. It was concluded that the seismic damage to bridges was higher when the magnitude of the earthquake was large or nearer to the epicenter.

기존 발표된 CLIMEX 매개변수와 RCP 8.5 시나리오에서의 기후자료를 이용하여 우리나라 금지급 과실파리 12종의 국내에서의 향후 기후적합도를 산출하고 국내정착가능 여부를 평가하였다. 열대내지 아열대성인 Anastrepha ludens와 A.obliqua, Zeugodacus cucurbitae, Bactrocera latifrons, B.tryoni, Ceratitis capitata, C.rosa는 모두 2010년대에는 제주도 남부지방 또는 해안가 일부가 경계 지역으로써 정착 가능한 것으로 평가되었다. B.correcta와 B.zonata는 2010년대에 제주 산간을 제외한 전역과 남해안 극히 일부 지역이 경계 지역에 포함되며, B.zonata, B.latifrons의 경우 제주에 적절내지 최적 지역이 형성되었다. 중북부, 내륙에서 이들 종의 기후적합성이 부적절한 것은 주로 저온 스트레스에 의한 것으로써 지구 온난화에 의해 기온이 상승하면서 2090년대에는 경계지역 범위가 해안가를 따라 상승하였다. 한편, B.tsuneonis와 Rhagoletis pomonella는 온대성 과실파리로서 주된 스트레스 요인은 습윤 스트레스였다. B.tsuneonis 는 2010년대부터 국내 산간을 제외한 대부분 지역이 이들 종의 최적 지역에 포함되었으며 그 범위는 점점 확장되었다. R.pomonella는 국내 대부분 지역이 적절 지역으로 평가되나 2050년, 2090년대에는 제주도 산간을 중심으로 정착 부절절 지역의 면적이 확장되었다. 한편, R.indifferens는 국내 중부지역을 중심으로 한 중산간 지역이 경계내지 적절 기후로 평가되나 정착가능 면적은 점차로 좁아져 2090년대에는 산간 극히 일부지역만 경계 지역으로 포함되었다.

Recently, most of the information system use environment is changing to GUI environment based on windows and web. Most of the development tools for building such a GUI-based information system support object-oriented and event-driven programming concepts. However, there is still a lack of a development methodology that systematically supports event-based information system construction. From a business perspective, an information system is one that supports business processes efficiently and effectively to improve business performance. These business processes are composed of business activities which involve a series of business events. A business event is executed according to a business scenario. Therefore, it is necessary to grasp these events in the requirements analysis stage and to apply it on the system development methodology. However, information systems development methodology which systematically reflect the event processing concept still is insufficient. From this viewpoint, this paper proposes an event-driven scenario-based development methodology that can meet the recent development environment of information systems, and applies the proposed methodology to a small scale information system development case.
