박은아(Euna Park),안재광(Jae-Kwang Ahn),황의홍(Eui-Hong Hwang),김정규(Jung-Kyu Kim) 대한지질학회 2021 대한지질학회 학술대회 Vol.2021 No.10

전통적으로 사용되던 네트워크 방식의 지진조기경보시스템은 상대적으로 속도가 빠른 P파를 기반으로 지진 정보를 생산하고 피해가 예상되면 경보를 전파한다. 네트워크 방식의 지진조기경보는 다수의 관측소에서 탐지된 P파 정보가 필요하기에 관측망의 조밀도가 높을수록 공백역(blind zone)이 줄어든다. 여기서 공백역이란 지진조기경보 이전에 큰 진동이 도달하는 영역이다. 하지만 지진조기경보의 공백역을 줄이기 위해 관측소를 늘리는 것은 부지확보부터 관리까지 막대한 비용이 소요되며 비효율적이다. 이러한 이유들로 최근 전자기기를 활용한 지진 감지 기술 개발이 활발하게 진행되고 있다. 초소형 전자기기들은 진동을 감지할 센서, 자료를 송수신할 통신 모듈 및 전력 공급만 있다면 저비용으로 활용이 가능하다는 장점이 있기 때문에 관측망 조밀도 향상에도 유리하다. 이에 기상청에서는 SK 텔레콤과 협력하여 초소형 MEMS 가속도 센서 기반의 관측망 확장 연구를 시작하였다. 2020년까지 전국의 기상청 지진관측소와 SKT 기지국 및 대리점에 총 2,783개소의 MEMS 관측망을 구축하여 현재 운영 중에 있다. 기존 설치 장소의 특성상 도서, 산간 및 해안지역에 관측소가 부족하다 한계점을 해결하고자 금년에는 우정사업본부와 해양경찰청, 소방청과 협의하여 관측망 확장을 추진하였다. 관측망의 확대 설치 후 발생한 2021년 7월 31일 M2.5의 대구 지진을 이용하여 지진 감지 및 관측망 확대 효과 분석을 수행하였다. 확대 설치 전후를 가정하여 지진 감지 관측소 수를 비교했을 때, MEMS 센서 유효 진앙거리 이내에서 P파 감지 관측소 수 증가로 인한 관측망 확대 효과를 확인하였다.

박은아(Euna Park),송해덕(Hae-Deok Song) 중앙대학교 한국교육문제연구소 2014 한국교육문제연구 Vol.32 No.4

본 연구의 목적은 대학생의 핵심 역량 중 하나인 의사소통 역량 향상에 영향을 미치는 학습자 요인을 탐색하는 것이다. 의사소통 역량이 실제 교수·학습 상황에서 길러지는 역량임에도 불구하고 그동안 의사소통 역량과 관련된 연구들은 주로 교수법 개발이나, 일반적인 학습자 특성 등을 중심으로 이루어져 교수학습 맥락을 고려하는 데 미흡한 부분이 있었다. 따라서 본 연구에서는 교수·학습 맥락에서 의사소통 역량과 관련한 학습자 요인으로 의사소통 관련 수강 과목 수, 의사소통 중심 수업활동, ICT 활용 수업에 대한 유용성 인식을 설정하고, 각 요인이 의사소통 역량 향상에 미치는 영향을 다중회귀분석을 통해 검증하였다. 그 결과 의사소통 역량 향상에 가장 큰 영향을 주는 요인은 ICT 활용 수업에 대한 유용성 인식으로 나타났다. 끝으로 연구결과에 근거하여 대학생 의사소통 역량향상에 대한 시사점들이 제시되었다. The purpose of this study is to explore factors influencing the communication competence that draws attention as the key competency of the university learner. Many studies examined the factors affecting the improvement of learners’ communicative competence but are limited in the aspect of ignoring the learning environment and learner characteristics; that is, ICT utilization and the consideration for the attitude and awareness of the learner. The influence of three factors were examined: the numbers of communication courses that were taken, interaction between instructors and students, and perceived usefulness of ICT utilization class as independent variables. Factors that most influenced the improvement of communication competency were analyzed through multiple regression analysis of 4,030 university students. Findings shows that the more students thought that ICT utilization class was useful, the more they felt that their communication competences were improved. Through these results, this study found that the utilization of ICT in class helped learners improve communication competency, and suggested implications for communication teaching and studies.
