PURPOSES : This study aims to suggest how to utilize "standby data" of shared mobility that does not contain personal information and examine whether "standby data" can derive existing shared mobility operation analysis items similarly. METHODS : An existing Personal Mobility (PM) traffic pattern analysis was performed by identifying the user (User ID) and the user's route in a time frame. In this study, the PM traffic pattern analysis focuses on a vehicle (ID of the standby vehicle) and its standby location. We examined whether the items derived from the User ID-based traffic pattern analysis could also be derived from the standby Vehicle ID-based analysis. RESULTS : The analysis showed that all five items (traffic volume by time slot, peak time, average travel time, average travel distance, and average travel speed) of the existing User ID-based PM travel analysis result could be derived similarly using the standby Vehicle ID-based PM traffic analysis. However, the disadvantage is that the average driving distance is calculated as a straight-line distance. It seems possible to overcome this limitation by correcting the average driving distance through linkage analysis with road network data. However, it is not possible to derive the instantaneous maximum speed or acceleration/deceleration. CONCLUSIONS : In an era in which various means of transportation are being introduced, data sharing is not preferred because of legal issues.Consequently, it is difficult to understand the use of new means of transportation and formulate new policies. To address this, data sharing can be active based on standby data that is not related to personal information.

Purpose: This study verified the effects of simulation-based communication education on the problem-solving process, communication self-efficacy, and communication ability of nursing college students. Methods: As an experimental study of single-group pre- and post-design, data were collected from April 12 to June 18, 2021, using a self-report questionnaire from 55 Year 4 nursing college students in city D. The collected data were analyzed in terms of frequency, paired t-test, and Pearson's correlation coefficients using the SPSS/WIN 23.0 program. Results: Our findings indicated that there were significant differences between the problem-solving process (t=-20.54, p<.001), communication self-efficacy (t=-15.31, p<.001), and communication ability (t=-3.62, p=.001) in communication before and after simulation-based communication education. Following simulation-based communication education, the communication ability of nursing students was evaluated through the problem-solving process (r=.46, p<.01), self-efficacy in communication (r=.37, p<.01), and problem-solving process by a doctor. Furthermore, it was found that there was a significant positive correlation with communication self-efficacy (r=.16, p<.01). Conclusion: It can be expected that the simulation -based communication education will improve nursing students’ problem-solving process, communication self-efficacy, and communication ability and thus contribute to high-quality nursing in related clinical situations. In addition, for a more effective communication education, research that could develop various scenarios in the clinical field and verify the effectiveness is required.

Its effects on learning attitude, problem-solving process, and clinical competence were then analyzed. Methods: This study used a one-group pretest–posttest experimental method among 135 fourth-year nursing students taking the simulation course at a university in D city. We operated the PBL by applying the structured discussion method and simulation education based on four modules covering major diseases among adults. The data collected before and after the program were analyzed using descriptive statistics and paired t-tests. Results: The program significantly improved nursing students’ learning attitude, problem-solving process, and clinical competence. Conclusions: We verified the effects of the simulation education program for structured discussion-based learning and PBL. Further studies are needed to develop and apply simulation educational programs utilizing various devices that can improve learners’ participation and professors’ operational protocols by systematically combining them with different teaching/learning methods.

이 작업의 주된 목적은 문화예술 기반의 도시재생과 계급 문제에 대한 현시대적 함의를 부산과 창춘의 사례분석을 통해 도출하려는데 있다. 실지로 문화예술 기반의 도시재생이란 역사사회적 맥락에서 문화예술의 상상력 및 실천력과 철학의 비판력을 절합하는 대화만큼 중요한 것은 없다. 그 대화를 통해 서로는 한층 더 풍요로워질 수 있고, 그 풍요로움을 통해 ‘도시 공동체로서 창조적 장소 만들기’라는 현시 대의 사회적 의제는 젠트리피케이션의 폐해를 극복하는 추동력으로 변모할 수 있다. 그뿐만 아니라 그 과정을 차근차근 밟아갈 때 현시대 문화실천가는 비로소 도시에 대한 자신의 권리를 더욱더 강력하게 주장할 수 있는 연대를 도모할 수 있게 된다. 그리고 이 모두는 시민 자신의 힘으로 더 정의로운 도시를 가꿔나갈 수 있는 토대로 작동하게 된다. ‘또따또가’와 ‘무단거리’의 두 사례를 포함해 지금껏 이 작업에서 해 왔던 논의 모두는 바로 이 같은 주장을 뒷받침하도록 설계된다.

Purpose: This study examines the effects of clinical nursing simulation education program based on problem-based learning (S-PBL) on clinical reasoning, confidence in handover reports, confidence in nursing performance, and simulation effectiveness in nursing students. Method: We used a one-group pretest-posttest design. The participants were 4th-year university nursing students who had taken a core clinical nursing practice, and 90 students participated in the S-PBL program. Data were collected before and after the S-PBL program and analyzed using descriptive statistics and paired t-tests. Results: The S-PBL program significantly increased clinical reasoning, confidence in handover reports, and confidence in nursing performance. More than 90% of students were satisfied with the education program and the simulation education effectiveness was 2.54 on a 3-point Likert scale. Conclusion: The S-PBL program could be useful in clinical nursing education for nursing students seeking to become clinical nurses. It is necessary to develop various S-PBL programs and apply them to the curriculum.

To make a satisfactory decision regarding project scheduling, a trade-off between the resource-related cost and project duration must be considered. A beneficial method for decision makers is to provide a number of alternative schedules of diverse project duration with minimum resource cost. In view of optimization, the alternative schedules are Pareto sets under multi-objective of project duration and resource cost. Assuming that resource cost is closely related to resource leveling, a heuristic algorithm for resource capacity reduction (HRCR) is developed in this study in order to generate the Pareto sets efficiently. The heuristic is based on the fact that resource leveling can be improved by systematically reducing the resource capacity. Once the reduced resource capacity is given, a schedule with minimum project duration can be obtained by solving a resource-constrained project scheduling problem. In HRCR, VNS (Variable Neighborhood Search) is implemented to solve the resource-constrained project scheduling problem. Extensive experiments to evaluate the HRCR performance are accomplished with standard benchmarking data sets, PSPLIB. Considering 5 resource leveling objective functions, it is shown that HRCR outperforms well-known multi-objective optimization algorithm, SPEA2 (Strength Pareto Evolutionary Algorithm-2), in generating dominant Pareto sets. The number of approximate Pareto optimal also can be extended by modifying weight parameter to reduce resource capacity in HRCR.

Purpose: The purpose of this study was to identify the effects of learner-directed debriefing based on the clinical judgement model (LDCJM) on nursing students’ critical thinking disposition, selfdirected learning, problem-solving ability, and debriefing experience after simulation. Method: This study used a quasi-experimental design with 38 sophomore nursing students from one university. They were divided into an experimental group (n=20) and a control group (n=18). Collected data were analyzed by the Chi-square, the Mann-Whitney U-test, and the Wilcoxon signed-rank test using the WIN SPSS 22.0 program. Results: The experimental group that had participated in the LDCJM indicated significantly higher self-directed learning (U=23.50, p<.001), problem-solving ability (U=94.50 p=.011), and debriefing experience (U=87.00, p=.006) when compared to the control group. Conclusion: The results indicate that LDCJM is an effective learning strategy to improve self-directed learning, problem-solving ability, and debriefing experience. Further study is needed to identify the effects of various debriefing skills.

본 연구에서는 사회적 도전과제 해결을 임무로 설정하여 이론과 정책을 개발 하고 있는 임무지향적 혁신정책론의 관점에서 사회문제 해결형 연구개발정책을 점검하고 그 시사점을 살펴본다. 이를 위해 시민사회의 참여, 정부의 동태적 능력의 확보, 선도적 투자와 후속 투자의 유도의 측면에서 ‘제2차 과학기술기반 사회문제 해결 종합계획’을 분석했다. 이 계획은 사회문제 해결형 혁신을 위한 시민참여의 제도화, 정부의 조정·통합능력 강화와 새로 운 생태계 형성을 위한 제도들을 도입하고 있다. 그러나 기존 활동의 경로의존성이 있기 때 문에 이를 넘어서기 위한 구체적인 프로그램이 요구되는 상황이다. 또 선도적인 투자를 이끌 어내기 위해서는 커뮤니티 케어, 기후변화 대응과 같은 사회정책 분야의 전략 사업과 혁신정 책을 통합적으로 전개하는 것이 필요하다.

Purpose: The purpose of this study was to examine the impact of a problem-based simulation education program on nursing student’s academic achievement, academic efficacy, and clinical performance skills. Methods: This study examined a group of nursing students using the pretest-posttest test design. Second year pediatric nursing students studying the practical subject Integrated Simulation at S University in K region were asked to complete a self-administered questionnaire before and after using a problem-based simulation education program. In addition to using SPSS/WIN 21.0 for descriptive analysis, the data was analyzed using independent t-test, repeated measures ANOVA and Pearson- correlation. Results: After completing the simulation education program, participants showed statistically higher academic achievement (t = -5.795, p < .001) and clinical performance skills (t = -3.835, p = <.001) than before. However, there was no significant difference in academic efficacy score(t=-.217, p=.829). Conclusion: The results from this study indicate that lessons with various methods and content should be developed to –evaluate both theoretical knowledge and clinical performance skills. In addition, there is a need to develop a standard evaluation.

Purpose: The purpose of this study was to investigate the effect of simulation training using video debriefing on the self-efficacy, problem solving ability, and learning satisfaction of nursing students. Method: The study design was control group pre-and post-test non-synchronized experimental design. The sample included two teams of 138 nursing students. The experimental group provided feedback after the simulation was run, and then the team was debriefed through the video recorded video in the debriefing room, and the control group performed the oral debriefing. This study was conducted from November 10, 2015 to December 10, 2015, using descriptive statistics, χ²-test and t-test. Results: The scores of the self-efficacy, problem- solving process performance, and learning satisfaction were higher than those of the group who received the video debriefing (experimental group) than those who received the oral debriefing training (control group). Conclusion: It has been found that debriefing using video in the simulation training has a positive effect on self-efficacy, ability to perform problem solving process and improvement of learning satisfaction, so it can be utilized as an effective teaching and learning strategy and also helps strengthen nursing capacity.

A missile defense system is composed of radars detecting incoming missiles aiming at defense assets, command control units making the decisions on weapon target assignment, and artillery batteries firing of defensive weapons to the incoming missiles. Although, the technology behind the development of radars and weapons is very important, effective assignment of the weapons against missile threats is much more crucial. When incoming missile targets toward valuable assets in the defense area are detected, the asset-based weapon target assignment model addresses the issue of weapon assignment to these missiles so as to maximize the total value of surviving assets threatened by them. In this paper, we present a model for an asset-based weapon assignment problem with shoot-look-shoot engagement policy and fixed set-up time between each anti-missile launch from each defense unit. Then, we show detailed linear approximation process for nonlinear portions of the model and propose final linear approximation model. After that, the proposed model is applied to several ballistic missile defense scenarios. In each defense scenario, the number of incoming missiles, the speed and the position of each missile, the number of defense artillery battery, the number of anti-missile in each artillery battery, single shot kill probability of each weapon to each target, value of assets, the air defense coverage are given. After running lpSolveAPI package of R language with the given data in each scenario in a personal computer, we summarize its weapon target assignment results specified with launch order time for each artillery battery. We also show computer processing time to get the result for each scenario.

결합 기반 페리다이나믹 모델을 통해 다양한 동적취성파괴 현상을 해석할 수 있었지만, 결합 기반 모델은 다양한 재료 구성 모델을 표현하는데 여러 한계를 보여왔다. 특히 결합 기반 모델은 각 결합들이 서로 독립적으로 작용하도록 가정하였기 때문에 3차원 모델에서 포아송비가 1/4로 고정되며 전단 변형이 표현되지 못하고 체적 변형만이 모사되는 문제점이 있다. 본 연구에서는 상태 기반 페리다이나믹 모델을 통한 동적취성파괴 해석을 제시한다. 상태 기반 모델은 일종의 일반화된 페리다이나믹 모델로서 일반적인 재료 구성모델로부터 직접 페리다이나믹 재료 모델을 구성한다. 또한 연결된 모든 결합의 변형을 통해 각 절점의 재료 응답이 결정되기 때문에 체적 및 전단 변형이 모두 표현된다. 본 논문에서는 선형 탄성체에 대해서 상태 기반 평면 응력 페리다이나믹 모델을 소개하고 상태 기반 모델에 적합한 손상 모델에 대해 논의한다. 페리다이나믹 비국부 영역을 축소시키는 δ-수렴성 연구를 통해 동적파괴 모델을 검증하고 상태 기반 모델이 동적 균열 전파를 모델링하는데 적합함을 확인하였다.
