차대 보행자 교통사고는 발생빈도에 비하여 사망률이 매우 높은 특징이 있다. 전세계적으로 정부 및 보험사에서는 보행자 보호를 위한 새로운 안전기준을 수립 및 강화하는 추세이다. 보행자 보호 성능을 향상시키기 위하여 한국정부는 2007 년부터 신차안전도평가에서 보행자 안전을 평가하고 있다. 보행자 보호 성능은 점진적으로 향상되었으나 여전히 미흡한 상태이다. 전개형 후드 및 보행자 에어백 등으로 구성되어 있는 보행자 보호 시스템은 보행자 보호를 위한 대안이 될 수 있다. 보행자의 머리상해기준값을 감소시키기 위하여 새롭게 정의된 설계방법론을 바탕으로 보행자 에어백 설계 절차를 제안하였다. 제안된 설계방법론을 실용적인 측면에서 검토하였고 보행자 보호 시스템의 제작에 적용이 가능하다.

There is a need to analyze various factors in evacuation safety assessment of building in fire. In the current performance based design, evacuation safety assessment in case of fire is being conducted through the simulation as FDS and Pathfinder. However, the location and size of the door, the location of evacuation in the event of a fire are not considered when design. Accordingly, it is difficult to determine the worst case scenario considering the actual fire. Therefore in this study, in this study, we will propose an appropriate evaluation plan through simulation considering the worst-case scenario that may occur in case of fire.

For the scheduling and the job assignment of the ship hull production design which is a process-based work, we suggest the simulation-based scheduling using the discrete-event-based business process simulation. First, we analyze the ship hull production design process from the perspective of a job assignment to make it into the simulation model using DEVS (Discrete Event System Specification) which is the representative modeling method for a discrete-event simulation. Based on the APIs of the open-source discrete-event simulation engine, we implement the simulation using the Groovy script. We develop the scenario generator in which the user defines detail information of the construction drawing and its member blocks, and design engineers information, and the various setting for the simulation including the job assignment strategy. We use the XML files from this scenario generator as inputs of simulation so that we can get simulation result in forms of Gantt chart without changes of the simulation model.

Interior design especially the design developments for commercial spaces should ensure the economy of spaces. This is the marketing for space. It is necessary to understand the design elements of commercial space for the efficient using of digital media of space marketing. In this research decided to design application schemes for shopping mall by searching fashion shopping behaviors of users with persona-base scenario approach. Collected the information of users behavior base on case analysis of advance research to make personas. And develop scenario base personas for knowing the needs of users. And then made 4 schemes as the solution. Scheme 1. Customers can get the information and communication with the staff through with media screen in one room of shopping mall. The data of customers can be recorded for providing information or product recommendation personality. Forecast to preferred by group trip or customers that don't like walking around in shopping mall. Scheme 2. Install a media screen at entrance of a store in shopping mall and show special effect to raise customers' attention who walk through from the front of the store. Through with this customers will stay for long time and raise curiosity to get in the store. And the media screen also provide information of store and products. Scheme 3. Customers can get the information of products with using smart phone to scan QR cord in labels of products and record. Customers can finish whole shopping behaviors without the help of store staff. And can make buying decision even have left shopping mall as a online mode. Scheme 4. Store managers can record the products and the environment of store with 360 camera and update to website. Then customers can browse the virtual space with VR glasses. That make customers can have the real shopping experience without being in the store. In this study, have presented schemes of digital media in commercial space. But there are various of commercial space. In this study was presented schemes for shopping mall by searching fashion shopping behaviors of users. And look forward the researches about specific space setting and other type of commercial space for space development.

최근 지구온난화가 가속화되면서 전 세계적으로 기록적인 기상재해가 급증하고 있다. 특히 강우패턴의 변화로 인하여 강우강도가 증가하여 집중호우의 발생빈도가 높아지고 있다. 본 연구에서는 기후변화 시나리오에 따른 강우패턴의 변화를 반영하여 목표연도 확률강우량을 산정하는 비정상성 강우빈도해석법을 제안하였다. BCM2 모형(A2 시나리오)과 NCEP 자료를 K-NN 축소기법을 사용하여 축소시킨 연 총 강우량을 이용하여 연 최대 강우량 평균, 연 최대 강우량 평균과 매개변수 간 통계학적 관계를 분석하여 목표연도 확률강우량을 산정하였다. 분포형은 Gumbel 분포를 사용하였으며 매개변수 추정법은 확률가중모멘트법을 사용하였다. 국내에서 가장 긴 관측 강우자료를 가진 서울지점을 대상으로 모형의 적합성 검증을 실시하였으며, 2006년 현재 통계학적으로 증가경향성을 가진 7개의 강우관측지점에 적용한 결과를 분석하였다. 기후변화 시나리오에 따른 지역적 연 총 강우량의 변화는 미래 확률강우량의 증감에 영향을 미치는 것으로 나타났다.

Modern systems development becomes more and more complicated due to the need on the ever-increasing capability of the systems. In addition to the complexity issue, safety concern is also increasing since the malfunctions of the systems under development may result in the accidents in both the test and evaluation phase and the operation phase. Light rail transit(LRT) with passenger capacity between bus and subway is driven by an unmanned control, so safety issues of LRT in emergency shall be considered more carefully than other rolling stock. Modern railway system is a complex system and many actions in emergency are required. In this view, interoperability approach is effective to identify the related elements in emergency. In this paper, we propose the method to generate the fire response scenario of unmann ed LRT based on the outputs of systems engineering architecture design methodology. The proposed method is could be contributed to establish more reliable and applicable fire response scenario.

As the use of unmanned aerial vehicles increases, in order to expand the operability of the unmanned aerial vehicle, it is essential to develop an unmanned aerial vehicle traffic management system, and to establish the system, it is necessary to analyze the integrated navigation performance of the unmanned aerial vehicle to be operated. Integrated navigation performance is affected by various factors such as the type of unmanned aerial vehicle, flight environment, and guidance law algorithm. In addition, since a large amount of flight data is required to obtain high-reliability analysis results, efficient and consistent flight scenarios are required. In this paper, a flight scenario that satisfies the requirements for integrated navigation performance analysis of rotary and fixed-wing unmanned aerial vehicles was designed and verified through flight experiments.
