해양사고 분석을 위한 해양사고 재결서는 중요한 정보제공의 원천이며 재발방지를 위한 개선사항을 제시한 자료이다. 하지만 이는 보고서 형태로 구성되어 수량화 하여 데이터로 활용하기에는 한계가 있다. 본 연구에서는 이러한 해양사고 재결서를 원인요소와 결과요소로 구분하여 계층화작업을 시행하였다. 이를 통해 충돌사고에서 선박조우상황과 충돌부위와의 상관관꼐를 증명하기 위한 기초자료로 사용하고자 한다. .

The purpose of this study was to develop a test tool for convergence problem solving skill. To this end, constructs of convergence problem solving skill were defined in three domains: convergence attributes, convergence thinking, and convergence literacy domains. Thirty-seven pilot items were developed on the basis of the sub-categories for each domain that was defined through intensive literature review; problem solving & convergent thinking and creative thinking for convergence thinking domain, individual and social propensity for the convergence attributes domain, and convergence literacy as convergence literacy domain. Through an exploratory factor analysis, 30 items in the constructs of the test tool were confirmed. A confirmatory factor analysis result showed that the five construct models well captured the covariance between all the items well. Finally a statistical result shows that the reliability of the items and constructs were well established (Cronbach's α value= .963). Thus, the test tool for convergence problem solving skill developed in this study was statistically reliable.

미래사회가 요구하는 창의융합형 인재 육성을 위한 기초소양 함양을 위해 소프트웨어 교육이 의무화되는 등 컴퓨팅 사고력과 지능정보사회에 필요한 핵심역량인 협력적 문제해결력의 향상을 위한 소프트웨어 교육에서의 교수 학습 방법이 강조되고 있다. 이에 따라 본 연구에서는 감성적 사고와 창의적 사고력의 균형을 추구하는 디자인 사고와 실생활 맥락적 문제를 해결하는 메이커 활동을 결합한 디자인 사고 기반 메이커교육을 소프트웨어 교육에 적용하여 초등학생의 협력적 문제해결력에 미치는 영향을 검증하고자 한다. 이를 통하여 디자인 사고기반 메이커 교육의 학습효과를 밝히고, 초등학교 수업에서 다른 교과목과 융합한 소프트웨어 교육의 적용방법에 대한 시사점을 제공하고자 한다.

Along with the recent technological development, autonomous vehicles are being commercialized. but The accident of autonomous driving car is becoming an issue, and safety problem of autonomous driving car is becoming a hot topic. Also There are currently no specific guidelines for clear laws and security ethics. These guidelines require a lot of information and experience. This study establishes basic guidelines based on cases of accidents from past to present. This study suggests security considerations through case study of security ethics in autonomous car accident.

Most of security countermeasures have been implemented to cope with continuous increase leakage of technology, but almost security countermeasures are focused on securing the boundary between inside and outside. This is effective for detecting and responding to attacks from the outside, but it is vulnerable to internal security incidents. In order to prevent internal leakage effectively, this study identifies activities corresponding to technology leakage activities and designes technology leakage activity detection items. As a design method, we analyzed the existing technology leakage detection methods based on the previous research and analyzed the technology leakage cases from the viewpoint of technology leakage activities. Through the statistical analysis, the items of detection of the technology leakage outcomes were verified to be appropriate, valid and reliable. Based on the results of this study, it is expected that it will be a basis for designing the technology leaking scenarios based on future research and leaking experiences.

The purpose of this study is to investigate the effect of simulation practice combining problem-based learning on nursing knowledge, self-confidence, critical thinking tendency and problem solving ability. The subjects of this study were 45 students who took two courses of nursing situation practice in the fourth grade of S university in S area. Data were collected before and after the simulation exercise using the self-report questionnaire. The problem-based learning and the simulation practice convergence training were conducted for three weeks with two hours per week, and the post- integration nursing knowledge, self-confidence, critical thinking disposition, and problem solving ability scores were improved. Nursing knowledge, self-confidence, and critical thinking tendency were positively correlated with problem solving ability and proved the effectiveness of problem-based learning and simulation training. Therefore, education programs combining problem-based learning and simulation training on various topics should be developed and utilized.

화물 선박의 전복사고가 매해 발생하고 있음에도 화물을 측정하지 않고 서류에 의존하는 방식으로 화물을 선적하고 있습니다. 우리는 사고의 원인을 사전에 차단할 수 있는 자동 계측 시스템을 연구하였습니다. 본 논문의 시스템은 LiDAR 센서를 이용하여 비규격 화물이 멈추지 않고 자동 계측되어 인력과 시간의 소요를 줄이고 산출된 체적과 3D 모델을 제공합니다. 게다가 화물 차량에 실린 화물을 내리지 않고도 화물의 체적을 산출할 수 있어 항만의 효율성을 향상할 수 있을 것으로 기대합니다.

This study aims to identify and understand nurses' experience on patient safety accidents in general hospital. The qualitative research method was used to analyze the daily life of seven nurses who had experienced nursing safety accidents directly or indirectly in general hospitals. The nurses' experiences were divided into 7 categories and 24 subordinate properties and 7 categories were "unexpected experience", "missing caused by negligence", "facing the anxiety", "difficult of loneliness", "resignation from the hospital", "entering into conflict" and "being practiced a nurse". The results of this study will contribute to the establishment of policies for safety accidents in hospitals and also it will help to make a practical improvement plan to prevent the patient safety accident at the clinical site.
