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.

Recently, various network protocols have been developed to keep step with the rapid growth of Internet users. For the education of students in the computer networks classes, there have been many attempts to allow students experiment routers setting, operations and management of networks by themselves, in addition to the classroom lectures based on textbooks. One of the attempts is to install expensive real router experiment sets in laboratories for students, and one another is using router and network simulators for virtual experiments. This paper presents the design and implementation of NetSim, a scalable, component-based simulator environment for the network experimentation. NetSim expands the existing component-based JavaSim simulation tool for the education purpose, and it allows the design and experiment of various networks and protocols. For the evaluation of NetSim, it is shown that the network design and RIP-based router setting process is possible in NetSim.
