According to U.S. NTSB, accidents of scheduled airliners from 1989 to 1992 caused by the lack of SA consisted of approximately 80% of all aircraft accidents, which emphasized the importance of maintaining SA. Furthermore, all of the 27 domestic helicopter accidents between 1996 and 2005 were related with pilot SA and of these, 21 events were directly attributed to pilot errors. Therefore, SA is a matter of great importance to pilots. Following the pre-study of the relations between SA and pilot qualifications, the results of this study which deals with SA and pilot working careers show the statistical importance between those two factors.

온톨로지는 뛰어난 확장성과 다양한 표현력 등 많은 장점을 갖고 있기 때문에 이를 이용한 유비쿼터스 환경 구축이 최근 제기되고 있고 이러한 유비쿼터스 환경에서의 다양한 정보(컨텍스트)들을 수집하고 분석하기 위해서 상황인식 시스템의 필요성이 제기되고 있다. 이러한 이유로 몇몇 프로젝트에서 온톨로지를 이용하여 상황인식 미들웨어를 제작하였지만 이러한 기존 미들웨어의 온톨로지 모델은 추론과 학습 서비스에 대한 고려가 부족하였고 또한 W3C에서 최근 제안한 SWRL(Semantic Web Rule Language)[1]이 고려되지 않았다. 그러므로 본 논문에서는 유비쿼터스 환경에서의 상황인식 프레임워크의 학습 및 추론서비스 향상을 위해 컨텍스트의 타입을 정의하였고 또한 SWRL을 이용하여 규칙을 표현할 수 있도록 온톨로지를 모델링 하였다.

해상교통관제 업무의 최적화를 위하여 요구되는 인적요소 분야 중 관제사의 상황인식(SA: Situation Awareness)와 관제 업무부하(Workload)와의 관계성을 확인하는 것이 해상교통 분야에서는 중요한 실정이다. 이 연구에서는 관제사의 상황인식과 업무부하를 상황인식평가기술(SART)과 다차원 작업부하 지표(NASA-TLX)를 실제적으로 측정하고, 측정 결과를 비교함으로서 개념들에 대한 이해와 시스템적으로 관리할 수 있는 방법을 제시함으로써 해상교통관제사 전문성 제고방안에 기여하고자 한다.

Purpose: This study attempts to identify the level of awareness, ethical awareness, and decision-making among nursing students, in response to pandemic infectious diseases. Methods: Subjects were 210 nursing college students attending colleges in 5 cities and provinces nationwide. Data were collected from November 2017 to April 2018 using a self-administrated questionnaire, and analyzed utilizing descriptive statistics. Results: Considering the awareness of pandemic infectious diseases, the nursing students expressed high concern about the possibility of future outbreaks of pandemic infectious diseases and seriousness of the situation. There were numerous negative views on the response and stockpiling of drugs by the government. Ethical awareness of pandemic infectious diseases was high, with demands for accurate information and proper protective equipment. Overall, ethical decision-making when responding to pandemic infectious diseases represented a high score. Also, higher awareness levels of pandemic infectious diseases would result in increased ethical and ethical decision-making. Conclusion: In conclusion, we propose the introduction of an ethical education program for medical personnel and nursing university students, to enable the handling of future pandemic outbreaks of new infectious diseases.

The purpose of this study was to compare the differences between science teachers' preference and their students' awareness for teaching and learning methods according to classroom circumstance, with a focus on the 'Stimulus and Reaction' subject unit in middle school. A survey was given to teachers and students that concentrated mainly on the 8 grade 'stimulus and reaction' unit, it was followed by interviews with 5 students to and in the interpretation of the findings. The questionnaire participants consisted of 192 science teachers and 331 $8^{th}$ grade students. Lecturing was the teaching method which was most favored by teachers and mainly recognized by students followed by questioning, educational software and film/video. We could see difference of recognition between teachers and students from this result in application, review and attitude area. The teaching methods applied by teachers and recognized by students depended on the instructional situation. In addition, it was revealed that teachers were applying various teaching methods to classroom situations.

Children in schoolzone accidents occur frequently in order to actively respond to the situation on the module for automated recognition research. By the vehicle penetration such like schoolzone, child object recognition, and GPS coordination information, the monitoring scenario can be constructed, and if an event occurs corresponding to strategic scenario so that suitable reaction can be provided to increase safety level to the schoolzone. In this paper, a GPS sensor and the image sensor and the monitoring server on the network based on the integration of context-aware methods have been studied. The image sensor section and the GPS section through analysis of the situation analysis and recognition of the object based on the scenario can actively cope with the situation according to the methods proposed.

Real Estate Auction Information System purposes on providing high quality information of auction customized to consumer's situation and preference. Especially, ever-changing real time information such as the number of hits and advanced analysis for expecting the winning bid are requiring of mobile information system based on context awareness. Therefore, this paper studies on Real Estate Auction Information System based on context awareness under a smart phone environment providing auction information such as consumer's current position, the number of hits to a specific real estate, and the number of bidder to anticipate the winning bid.

The advance of wireless telecommunication and observation technologies leads developing sensor and sensor network for serving the context information continuously. Besides, in order to understand and cope with the context awareness based on the sensor network, it is becoming important issue to deal with plentiful data transmitted from various sensors. Therefore, we propose a context awareness system to deal with the plentiful sensor data in a vast area such as the prevention of a forest fire, the warning system for detecting environmental pollution, and the analysis of the traffic information, etc. The proposed system consists of the context acquisition to collect and store various sensor data, the knowledge base to keep context information and context log, the rule manager to process context information depending on user defined rules, and the situation information manager to analysis and recognize the context, etc. The proposed system is implemented for managing renewable energy data management transmitted from a large scale area.

This study aims to inspect national security consciousness of marriage migrant women, and to figure out factors which affect on awareness of national security. Based on this, this study also suggests a way to build up national security of marriage migrant women. As the result of the factors on security situation, there were several things which are necessity of education, trust in the army and government, positivity toward North Korea and so on, while necessity of education, trust in the army and government, national pride and positivity toward North Korea were on the awareness of national security. There are three ways of building up national security consciousness of marriage migrant women. First, security education is needed to be in the social adjustment program of marriage migrant women. Secondly, concern on security is required to them. Third, a necessity of production on security education material is demanded for marriage migrant women.
