While the importance of barrier-free and fire evacuation design is highlighted in architectural design education, systemic analysis, and examination on such performances are still challenging due to methodological lacks. The present study investigates the effectiveness of BIM-based human behavior simulation for architecture major students' analytical examinations to promote barrier-free and fire evacuation performances. To achieve such an aim, quasi-experiments were conducted, which compare 50 students' analysis and examination scores according to the use and non-use of the simulation, and the data were collected via participants' survey and interview. As a result, T-Test and MANOVA analyses indicate that, compared with its non-use counterpart, the use of human behavior simulation better facilitates the students' (1) examination of the physical properties and dimensions for the disabled's accessibility and evacuation, (2) understanding of the bodily capacity and handicap of the disabled, (3) examination on the spatial layouts and locations of exits, (4) understanding on evacuees' urgent behaviors, and (5) responsibility as an architect. Based on previous studies, the reasons of statistical results are interpreted as the explicit observation and analytical measures of multiple numbers of virtual-evacuees and direct-experience from body range of the disabled responding to the populated occupants as what they face in authentic reality.

Purpose: This study was conducted to develop a simulation-based education program for newborn emergency care based on most needed topics found from the needs assessment. This study consisted of two phases: developing the program and evaluating its effectiveness. Methods: The effectiveness of the program was tested in July, 2012, with 49 junior nursing students from C Nursing College in Seoul, who did not have any clinical experience in newborn care. The experimental group was given a three-hour lecture, three hours of clinical training, and a two-hour simulation program, whereas the control group only had the three-hour lecture. Results: There was significant improvement in knowledge in both groups, but no significant differences according to educational methods. The experiment group was more confident of their care ($4.32{\pm}.29$) than the control group ($3.60{\pm}.29$) with the difference being significant (t=8.85, p<.001), and the experimental group was also more satisfied with the program (${\chi}^2$=4.60, p=.032). Conclusion: As the results indicate 'the neonatal emergency care program' increased learners' knowledge, confidence and satisfaction with the program, it should be integrated into clinical training in pediatric nursing curriculum and in-service programs for nurses. To increase generalization further verification studies with various learner groups are needed.

Simulators were introduced in education as a tool to make advanced training standardized, less expensive, and without danger to those involved. In 1922 in the Unites States, Edward Link presented his homemade flight simulator, which became common place in both military and civilian aviation, known as the "Link Trainer". The development of mannequin simulators used for medical simulation education, training, and research is reviewed, tracing the motivations, evolution to commercial availability, and efforts toward assessment of efficacy of those for teaching cardiopulmonary resuscitation(CPR) for medical personnel and emergency medical technicians(EMT), cardiology skills, anaesthesia clinical skills, and crisis management. This study will provide a brief overview of simulators and trainers in several domains.

Like other countries undergoing the aging of the population, increases in the aged population have raised serious issues in Korea. The proportion of elderly will be foreseen over $14\%$ of population in 2019, over $20\%$ in 2026 in korea. Due to the rapid increasing in the aged population, it calls for social countermeasures urgently, And recent researches about attitude to the aged find out in general negative attitude to the aged of other generations. It is thought desirable that comprehension to the aged of the commonalty should be educated on the school basis or a variety of informal ways. The study aims to determine the space formation of the senior simulation center that suggest to be considered for the effective education and preparation for the aging of all social members, particularly for the younger generation. In such space formation, it is important to work out a plan of efficiency education according to the systematic environmental setting with a focus on the minimization of problematic behaviors and living disabilities of aging, as interactive experiences gain malfunctions by aging. This study is expected to promote a focus on the integration of the whole generations and improved design management for the environment of a welfare policy for the aged.

In this study, the types of inquiry activities in the $5^{th}$ & $6^{th}$ grade science textbooks according to the 2015 revised science national curriculum were analyzed and compared according to grade level and science area. Science textbooks for elementary school $5^{th}$ & $6^{th}$ graders contain quite diverse types of inquiry activities, which are student-centered inquiry activities. There were comparatively higher proportions of inquiry types such as experiment & observation and simulation, but relatively lower of inquiry types of investigation-discourse & presentation, discussion, expression. Elementary science textbooks are expected to cultivate science key competencies for elementary school students. Considering the science area, the motion & energy, substances, earth & space, and integration areas had the most experiment & observation among activity types, while the life area had the most simulation activities. Even in some area of the 6th grade science textbook, there was little or no data interpretation, discussion, and simulation activities. In order to achieve the goal of elementary science education, science textbooks should be developed considering the revision of future elementary science curriculum.

Modeling approach for mesoscopic model of concrete depicting mass transportation and physicochemical reaction is important since there is growing demand for accuracy and computational efficiency of numerical simulation. Mesoscopic numerical simulation considering binder, aggregate and Interfacial Transition Zone (ITZ) generally produces huge number of DOFs, which is inapplicable for full structure. In this paper, a three-dimensional multiscale approach describing three-phase structure of concrete was discussed numerically. An effective approach generating random aggregate in polygon based on checking centroid distance was introduced. Moreover, ITZ elements were built by parallel expanding the surface of aggregates on inner side. By combining mesoscopic model including full-graded aggregate and macroscopic model, cases related to diffusivity and thickness of ITZ, volume fraction and grade of aggregate were studied regarding the consideration of multiscale compensation. Results clearly showed that larger analysis model in multiscale model expanded the diffusion space of chloride ion and decreased chloride content in front of rebar. Finally, this paper addressed some worth-noting conclusions about the chloride distribution and rebar corrosion regarding the configuration of, rebar diameter, concrete cover and exposure period.

This study investigates the virtual reality (VR) simulation to train construction workers for modular construction. Recently, the construction industry has been experiencing a growing demand for modular construction due to a shortage of labors and an increasing social need for safety. While the demand for modular construction has been increasing, construction labors suffer a basic knowledge regarding modular construction. The users of the simulation, developed by Unity program and Oculus Quest 2, experience the removal of hazardous elements at the location whether the modular unit suspended by a crane is lowered, the lowering and assembly of units through crane operation, and the fall from the roof which is the most frequent accidents in modular construction. The simulation was tested by 15 subjects. The effectiveness of the education was measured through a survey on self-efficacy, perceived usefulness, usability, and presence. It was found that the VR training is suitable for educating on the modular construction activities and safety issues related to them. This study also found that perceived usefulness is the factor that has the greatest impact on self-efficacy. This study can contribute to resolving the labor education issues for the deployment of modular construction.

In this paper, a Wireless USB (WUSB) protocol is adopted for development of ASMD (Adaptive Source Multi Device) N-screen wireless services. WUSB is the USB technology merged with WiMedia PHY and Distributed-MAC (D-MAC). However, the current WUSB protocol can't provide seamless N-screen streaming services to moving WUSB devices in home network environment. Therefore, to provide the ASMD N-screen services through WUSB based on D-MAC protocol, a channel management scheme is proposed to support seamless mobility between adjacent ASMD groups for wireless IPTV N-screen services. In simulation results, proposed ASMD channel management (ACM) scheme is compared with conventional WUSB channel management scheme in view points of throughput, average path interference and energy consumption according to various numbers of nodes and elapsed simulation times. Through simulation results, it is explained that proposed ASMD channel management (ACM) scheme should be adopted in the WUSB protocol to realize ASMD N-screen wireless services.
