현대는 국내여행 뿐만 아니라 국외여행도 쉽고 빠르게 다닐 수 있는 시대가 되었다. 그로인해 점점 여행을 즐기는 사람들이 늘어났다. 하지만 처음 가본 장소에서는 길을 잃기 쉽고 해외의 경우 현지 언어를 구사할 능력이 되지 못하면 도움을 받는 것 또한 어렵기 때문에 처음 가본 장소에서 쉽게 길을 찾을 수 있는 도구를 개발하려고 한다. 이전에는 군사용으로 사용되던 드론이 현재는 일반인들도 쉽고 조작이 간편하여 안전하게 즐길 수 있게 되었다. 드론은 활용분야 또한 폭 넓기 때문에 이번에 드론을 사용하여 길을 찾아주는 드론 네비게이션을 개발하려고 한다. 구글맵을 이용하여 사용자가 가고 싶은 목적지를 설정하면 사용자와 일정 거리를 유지한 채로 목적지를 향하여 날아가도록 만드는 것이 목적이다.

The purpose of this study is to investigate the value perception changes of early adolescents, who are from 5th grades to 7th grades regarding to agriculture and rural communities through debate education. Since current education policy to educate agricultural value is limited in solving stereotypes and acquiring abundant relevant knowledge about agricultural values, this study tried to test the effect of debate education for the change of value perception of early adolescents about agriculture and rural communities. Through the two weeks of a debate education course, the differences of perception changes between the experimental group and control group were analyzed. As a result, education on agriculture and rural communities through debate has a great influence on the change of value perception and thus, it could be used as a supplementary educational method for literacy education and field trip learning. Lastly, limitations and implications for the study is discussed.

The Core Protection Calculator System (CPCS) is vital for plant safety as it ensures the required Specified Acceptance Fuel Design Limit (SAFDL) are not exceeded. The CPCS generates trip signals when Departure from Nucleate Boiling Ratio (DNBR) and Local Power Density (LPD) exceeds their predetermined setpoints. These setpoints are established based on the operating margin from the analysis that produces the SAFDL values. The goal of this research is to create a simplified CPCS that optimizes operating margin for I-SMRs. Because the I-SMR is compact in design, instrumentation placement is a challenge, as it is with Ex-core detectors and RCP instrumentation. The proposed CPCS addresses the issue of power flux measurement with In-Core Instrumentation (ICI), while flow measurement is handled with differential pressure transmitters between Steam Generators (SG). Simplification of CPCS is based on a Look-Up-Table (LUT) for determining the CEA groups' position. However, simplification brings approximations that result in a loss of operational margin, which necessitates compensation. Appropriate compensation is performed based on the result of analysis. FPGAs (Field Programmable Gate Arrays) are presented as a way to compensate for the inadequacies of current systems by providing faster execution speeds and a lower Common Cause Failure rate (CCF).

Therefore, it Bs necessary to investigate the current status of Korean environmental education and provide teachers with appropriate environmental teaching/leaming methods. To this end this study aims to examine Korean science teachers'perceptions'on environmental education and the kind of teaching/learning methods which can be utilized in environmental education. Teachers who completed the survey were 135 science teachers from middle and high schools in Seoul, and 126 social science teachers from Kyoungki province. The majors of the science teachers were in physics, chemistry, biology, geology, and earth science. Also, there was one teacher who majored in special education. For social science teachers two majors were common, geography and general sociology. After analysis of the data from the surveys the results are as follows. First, science and social science teachers in middle and high school recognized the necessity of environmental education in school education. Second, most teachers had applied environment related topics to their subject of study occasionally, but they mostly concurred that environment related contents should be included in their textbooks. Third, science teachers agreed that field trip, discussion, and the STS approach were the most proper methods for environmental education, and social science teachers agreed that field trips, inquiry, and discussion were the most appropriate methods for a teaching environment. They realized that they should decide good teaching-learning methods appropriate to the objectives and content needed for effective environmental education as they selected different teaching-learning methods according to detailed environmental objectives and contents in their textbooks.

본 연구에서는 초등학교 교사를 대상으로 과학관의 교수-학습에 활용 현황 및 교육 프로그램에 대한 요구를 조사하였다. 연구 결과, 지금까지 과학관은 학교 교육과 밀접한 관계를 가지고 운영되지 못하였으며, 주로 일회적이거나 개인적인 활동으로 과학관 경험이 끝나는 경우가 많았음을 알 수 있었다. 또한 과학관이 교수-학습에 많이 이용되지 못하는 것은 그 교육적 효과가 미미해서보다는 외부의 물적 행정적 지원의 부족으로 인함을 알 수 있었다. 교사들이 선호하는 과학관 교육 프로그램은 캠프나 실험 등의 학생 위탁 프로그램과 학교 교육과 정과 관련된 전시물이었으며, 교사들에게 과학관과 관련된 다양한 활동에 참여하기를 물어본 결과 설문 대상의 약 80%의 교사가 과학관 학생 위탁 프로그램 개발, 과학관 투어, 캠프, 실험 등의 과학관 위탁 프로그램 운영 담당, 과학관 중심 교사 커뮤니티에의 참여, 과학관 방문 전후 프로그램 개발 등에 참여를 희망하였다.
