The main purpose of this study was to analyze the general informatization situation of North Korean defectors and to study the characteristics and needs of the learners in order to provide the directions of information education for them. The results of the study showed the following characteristics of the North Korean defectors: They are slow learners due to the fear of new devices, have difficulty in learning due to the unfamiliar language of information and English, and indifferent when the situation is not related to themselves. Based on these learner characteristics and needs, this study suggests the strategies of step-by-step repetition, use of North and South Korean dictionary of the information terminology, apply job-centered and communication abilities, and suggested a four-element STEP model. Raising the level of informatization of North Korean defectors will help establish a successful settlement to South Korea. This will be a valuable foundation and a stepping stone for the future unification of Korea.

여러 분야에서 다양한 목적으로 인간처럼 생각하는 시스템을 구현하고자 하는 연구가 이루어지고 있다. 인간의 뇌에서 기억을 담당하는 부분은 시각, 청각, 촉각 등의 감각 정보를 이용하여 새로 들어온 정보가 이미 기억된 정보와 같은가를 비교하여 기존 기억에 적용시키거나 새로운 정보로 기억시킨다. 기존의 모델은 ART를 사용하여 그것을 구현하고 반복 학습되지 않는 정보는 잊혀져 버리는 것과 강한 자극과 함께 입력된 정보는 반복 학습되지 않아도 잊혀지지 않는 것이었다. 그 모델을 이용할 경우 모든 감각에 대한 정보들이 전부 한 번에 처리되었기 때문에 감각별로 정보를 차등적으로 조절하여 처리하기가 곤란하였다. 본 논문에서는 이 문제를 개선하기 위해 기존의 ART를 이용한 모델에서 감각 정보를 비교하는 과정을 퍼지 규칙을 도입한 방법으로 교체하고자 한다. 우선 입력받는 감각 정보의 여러 값들을 감각 별로 그룹화 한 후 그룹별로 퍼지 규칙을 이용하여 비교한다. 기억된 정보들을 퍼지 규칙으로 하고 입력된 정보를 이용하여 각각의 규칙에 대한 결과를 낸다. 이 모델에서는 퍼지를 사용하여 기억된 정보에 대한 이해가 쉽고, 기억된 정보를 이용할 때 규칙을 조절하여 적용하는 것으로 상황에 따라 필요한 감각 정보를 알맞게 적용할 수 있을 것이다.

디지털 문화재 콘텐츠는 현실에서 체험하기 힘든 문화재를 디지털 기술의 특성을 이용하여 사용자의 경험을 극대화할 수 있고, 문화재 보수, 교육 등에 활용될 수 있다. 그런데 기존의 디지털 건축물 문화재는 실재 문화재의 구조 및 구성을 무시하고 외형만 만들어져 있어서 다양한 형태로 바꾸어 활용하기 곤란하며, 디지털 건축물 문화재 자체가 가상공간에 존재하여 현실체험에 제한을 받고 있다. 본 논문은 사용자가 현실공간에서 부재 미니어처를 이용하여 미니어처 문화재를 조립하고 그 결과를 가상공간의 디지털 문화재로 연결하여 다양한 체험을 제공하는 시스템에 관한 것이다. 이로서 현실 체험과 가상 체험이 연결되어, 보다 효과적인 체험이 가능하고 건축 문화재에 대한 보다 전문적인 학습이 가능하게 된다.

신생아 호흡곤란증후군(RDS, Respiratory Distress Syndrome)은 미숙아 사망의 주된 원인 중 하나이며, 이 질병은 빠른 진단과 치료가 필요하다. 소아의 x-ray 영상을 시각적으로 분석하여 RDS 의 판별을 하고 있으나, 이는 전문의의 주관적인 판단에 의지하기 때문에 상당한 시간적 비용과 인력이 소모된다. 이에 따라, 본 논문에서는 전문의의 진단을 보조하기 위해 심층 신경망을 활용한 소아 RDS/nonRDS 판별 방법을 제안한다. 소아 전신 X-ray 영상에 폐 영역 분할을 적용한 데이터 세트와 증강방법으로 추가한 데이터 세트를 구축하며, RDS 판별 성능을 높이기 위해 ImageNet 으로 사전학습된 DenseNet 판별 모델에 대해 구축된 데이터 세트로 추가 미세조정 학습을 수행한다. 추론 시 입력 X-ray 영상에 대해 MSRF-Net 으로 분할된 폐 영역을 얻고 이를 DenseNet 판별 모델에 적용하여 RDS 를 진단한다. 실험결과, 데이터 증강과 폐 영역을 분할을 적용한 판별 방법이 소아전신 X-ray 데이터 세트만을 사용하는 것과 비교하여 3.9%의 성능향상을 보였다.

In this study, learning materials that can be applied for web-based distant learning model were developed based on the characteristics of elementary school science in which investigation skills and thinking ability are considered to be important. And the effect of students' activity in a reports on student's investigating and thinking ability was investigated. While designing diverse experimental procedures, the students had. an opportunity to improve their observation attitude and way of scientific thinking. Such improvement was possible, only because the present web-based distant learning model consists of requiring an interaction between the students and a report and evaluation system which can put together such effort. Still, it was acknowledged that, as being in lack of teacher's direct support and supervision, the present web-based distant learning model might be somewhat ineffective in guiding the students in accordance with their own characteristics. For example, the students had a tendency to maintain their basic idea and style even when their reports are individually examined and corrected in terms of the format of the report.
