Recently, with the development of IoT, AI, and mobile terminals, medical information platforms are expanding. The medical information platform can determine a patient's emergency situation, and medical staff can easily access patient information through a mobile terminal. However, in the existing platform, emergency situation decision is delayed, and faster and stronger authentication is required in emergency situations. Therefore, we propose an edge computing-based medical information platform for automatic authentication using patient situations. We design an edge computing-based medical information platform architecture capable of rapid transmission of biometric data of IoT and quick emergency situation decision, and implement the platform data flow in emergency situations. Relying on this platform, we propose the automatic authentication using patient situations. The automatic authentication protects patient information through patient-centered authentication by using the patient's situation as an authentication factor, and enables quick authentication by automatically proceeding with mobile terminal authentication after user authentication in emergencies without user intervention. We compared the proposed platform with existing platforms to show that it can make quick and stable emergency decisions. In addition, comparing the automatic authentication with existing authentication showed that it is fast and protects medical information centered on patient situations in emergency situations.

Southeast Asian region cruise market is expected to be stable or grow in the near future depending on the region's economy. Star Cruises company, which has entirely dominated the regional market since 1998, has attempted to expand beyond traditional cruise routes in Southeast Asian region and develop new markets in Thailand and Dubai. Such a situation urges Korean shipyards to study on Southeast Asian region based cruise ships. This study is to suggest directions for planning of interior spaces of Southeast Asian region based cruise ships. In order to accomplish this purpose the market situation is analyzed and the adequate ship's tonnage(70,000grt class) is decided. According to mission-based design process the sizes of standard staterooms are set up first and then the sizes of the important structural parts of ship are calculated. Through analyzing the 26 cruise ships of 70,000grt class the kinds, locations and sizes of public rooms are grasped. And we inspect 4 cruise ships of Star Cruises, which are now being operated in Southeast Asian region to understand design characteristics of interior spaces.

피난과 관련된 대부분의 사인시스템은 벽의 상단부에 있다는 점에서 고개를 숙인 채 대피해야 하는 지진 상황에서 유용하지 않다. 본 연구는 지진 대피 상황의 분석과 이해를 바탕으로 신속한 지진 대피를 위한 대책으로서 사인 시스템을 제안하고자 한다. 첫째, 지진 대피 상황의 동영상 분석을 바탕으로 지진 상황을 이해한다. 둘째, 지진 상황에서 안전한 대피를 돕는 사인 시스템이 가져야 할 필요요건을 도출하였다. 셋째, 현장조사를 통해 국내에 설치되어 있는 사인시스템이 지진대피 상황을 위한 피난설비로서 적절한 기능을 갖추었는지 적합성을 고찰하였다. 동영상 분석 및 현장 조사를 바탕으로 피난유도등의 설치만으로는 지진 상황에서 신속한 대피를 유도할 수 없다는 결론을 도출하였다. 본 연구에서는 피난유도등 근처에 사인시스템을 설치하여 문의 사용성을 돕는 사인시스템을 제안한다.

상황인식은 비행 또는 항공기를 유지하는 작업에서 진행 상황을 파악하는데 필요한 모든 사항을 인식하는 것을 의미한다. 상황인식은 환경에 대한 정보를 단순히 인지하는 것 이상을 기본으로 하며 정보의 의미를 통합된 형태로 제공하는 것이 중요하다. 한국형 기동헬기는 통합된 형태의 상황인식을 위하여 통합 상황시현 및 우선순위 기반 청각 신호경고를 시각 신호와 동조하여 조종사에게 제공한다. 통합 상황시현 및 효율적인 경고 제공으로 운용자 과실을 줄이고 운용자에게 임무의 핵심작업 및 이벤트에 집중할 수 있게 한다. 본 논문은 한국형 기동헬기에서 구현한 통합 상황시현 및 경고 설계를 소개한다.

Objective: This study proposes the application of Ecological Interface Design(EID) method that is effective for situation awareness in digitalized environment. Background: While cognitive interface design method such as Information Rich Display(IRD) is simply focused on existing information for user, EID method helps users' resource to be solved to higher ion task such as diagnostic and problem solving. Method: Using EID method based on Work Domain Analysis (WDA), it was analyzed and designed for Steam Generator(SG) Water Level control process in a digitalized Main Control Room of Nuclear Power Plant. Proposed EID example is evaluated through interviews by expert & operator. Results: The result of expert & operator showed that EID display might give an aid for operator's decision. Conclusion: The results can reduce critical accidental damage that occurred due to cognitive load and so critical human error. Application: This study may be impact on situation awareness study for digitalized interface design.

Most of seismic designs of major structures up to now have been performed by the traditional 'force-based design' approaches. However, they are not so efficient to evaluate the structural deformations by potential nonlinear behaviors which are directly related with the damages or performance levels during earthquakes. Lately, based on this situation, various kinds of new seismic design approaches based on the deformation, which is called 'displacement-based design' procedures, have been proposed. In this paper, most of detail techniques and procedures of the new design methods in the literature are comparatively reviewed and evaluated first, followed by a series of design examples of typical bridge structures. Comparing the results with those of the existing force-based design, the improved levels of performance and economy of the displacement-based seismic design have been validated.

To understand whether Falling, which is one of the causes of injuries, occurs, various behavior recognition research is proceeding. However, in most research recognize only the fact that Falling has occurred and provide the service. As well as the occurrence of the Falling, the risk varies greatly based on the type of Falling and the situation before and after the Falling. Therefore, when Falling occurs, it is necessary to infer the user's current situation and provide appropriate services. In this paper, we propose to base on Fog Computing and Cloud Computing to design Context-aware System using analysis of behavior data and process sensor data in real-time. This system solved the problem of increase latency and server overload due to large capacity sensor data.

This study defined the pre-elderly as middle age people from 50 to 59. Because it is difficult to produce a design to satisfy the pre-elderly without deeply understanding them, their financial and physical characteristics and persona-based scenario method was studied. An experimental study about persona based scenario method was conducted, and as a result, the types of personas found were as follows: 1) Users enjoy the same games online and offline. 2) Users enjoy playing alone on the computer. 3) Users prefer games that end quickly with win or loss. Writing the situation scenario for each type, the pre-elderly's problems and needs occurring while they play web board games were obtained. The obtained user requests were as follows: users would like the level of difficulty to be simpler in the game of baduk; users wanted unlimited credit and refrainment from using English words in go-Stop; and there were simple comments about game screen design.

The vehicle oriented block box system based on the u-healthcare and the human-free guard functions is developed in this paper. We also suggested the design philosophies, ideas, and analyzed the performance of the suggested system. The developed vehicle oriented black box system has some characteristics such as; 1) detects the dangerous situation by ultrasonic sensor in advance, and stores the situation information of the neighborhood of the vehicle to the imbedded SD memory card if the dangerous situation may be occurred in the parked vehicle; 2) detects the present location and speed information of the vehicle by GPS receiver and 3-axes acceleration sensor, and stores the information to the SD memory card periodically if the vehicle is running; 3) measures the dioxide carbon in the vehicle inside using $CO_2$ sensor, and forces the ventilation motor of the vehicle to operate and maintains the driver's health if the measured level is more than standard health requirements; 4) provides the stored vehicle's operating information to the driver by GUI (Graphical User Interface) based touch LCD monitor.

This paper aims to build a drone platform based on an optimum design of its single arm. We assumed its single arm as a cantilevered beam with a tip mass. Based on the numerical optimization theory, we conducted validation and optimization of a new design by comparing the results with the similar ones obtained by ANSYS. Finally, this design is reflected in the control simulation, and the requirement of an optimum structural design considering the resonance situation is demonstrated.
