Information and communication technologies(ICT) allow and force people to work anywhere, anytime using remote databases and application systems available in real-time twenty four hours a day and seven days a week. With the real time nature of ICT, individual work is becoming more and more fragmented. Instead of working on a similar task repeatedly, individuals are required to respond to e-mails and inquiries through social networks, work on planning documents, work on presentation documents, work on spreadsheets, input necessary data on company databases, generate necessary reports from the database, run teleconference, etc., all maybe in a day's work. Work fragmentation may impact negatively on productivity as the flow is interrupted, but it may increase the productivity by allowing people to handle multiple tasks in a shorter time period. This study explores the types of work fragmentation and their characteristics. An online survey was administered to collect data about work fragmentation and work characteristics including autonomy, complexity, flexibility, usage of ICT, etc. 300 cases were used in the analysis. Analysis of k-mean cluster indicated four different types of work fragmentation: concentrated, temporally distributed, spatially distributed, and fully fragmented.

본 논문에서는 최대 규모의 게임 플랫폼인 Steam에서 수집한 유저 정보 데이터 셋에 Item2vec과 LSTM을 사용하여 추천 시스템을 구현한다. 수집한 유저 정보 데이터 셋에 Item2vec을 적용하여 각각의 유저들이 보유하고 있는 고유한 Appid들을 200차원의 벡터로 변환한다. 그 후 데이터 셋을 기간에 따라 4단계의 시퀀스로 나눈 후 LSTM을 사용하여 유저별로 최대 5가지의 추천 리스트를 생성한다. 유저 정보 데이터 셋은 액티브한 유저 정보를 얻기 위해 Steam 게임 리뷰 항목에서 리뷰를 남긴 유저들의 데이터를 api를 사용해 수집했으며 LSTM을 사용한 실험의 성능 평가 지표는 RMSE를 사용했고 이때의 성능은 0.1357을 얻을 수 있었다.

In our information society, ICT education is becoming basic and fundamental task that many countries are putting emphasis on it, considering it as "the most important step in reformation of education." ICT education have many differences in many countries. Currently, we are considering the suggestions for ICT education in Korea, and through comparative analysis of ICT education in Turkey, a country which has similar economic and cultural conditions, we will provide helpful solutions on ICT education policy for mutual countries. For an objective comparative analysis. we used the PISA 2009 and PISA 2012 data. The results show that Korea is has a better and easy access to computer at home only. Accessability to information devices in school, computer use in schools, and the students aptitudes on using the devices were excelled by Turkey. General attitudes about computers was similar, but Turkey proved to be better at utilizing computers in schools settings. With these findings, Korea must redefine current ICT education policies and establish policies for activating the ICT education nationwide.

The purpose of this study is to develop a system for predicting students' collaborative problem solving ability based on the ICT factors of PISA 2015 that affect collaborative problem solving ability. The PISA 2015 computer-based collaborative problem-solving capability evaluation included 5,581 students in Korea. As a research method, correlation analysis was used to select meaningful variables. And the collaborative problem solving ability prediction model was created by using the deep learning method. As a result of the model generation, we were able to predict collaborative problem solving ability with about 95% accuracy for the test data set. Based on this model, a collaborative problem solving ability prediction system was designed and implemented. This research is expected to provide a new perspective on applying big data and artificial intelligence in decision making for ICT input and use in education.

In this study, we compared the use of information and communications technology (ICT) by middle school teachers in Korea and other countries utilizing the teacher survey data of the IEA International Computer and Information Literacy Study (ICILS) 2013. The ICILS target population consisted of all students in the eighth grade. We compared Korea with Australia, the Czech Republic, Norway, and Poland, which are nations showing the highest achievements in computer and information literacy. We selected nine questions from the teacher questionnaire and divided them into the categories of computer use, use of ICT for teaching and learning, and the ICT support environment in school. In comparison to their counterparts in other countries, Korean middle school science teachers used computers frequently and also had high ICT self-efficacy. They were confident in their ability to use computers for general tasks, but not in their ability to use computers for teaching and learning. The Korean teachers also had a high percentage of utilization of presentation and graphics software. Also, the proportion of activities concerning the information provided and teacher-led tasks was high, but the proportion of activities for student collaboration or peer interaction was low. In Korea, middle school science teachers had more negative than positive views of using ICT in teaching and learning. The teachers thought that computer-related resource support and digital learning materials were insufficient and that the computer model was outdated in schools. Therefore, we propose to build an ICT infrastructure and to develop and disseminate ICT teaching and learning methods for student activities.

교육인적자원부의 ${\ulcorner}$초${\cdot}$중등학교 정보통신기술 교육 운영지침${\lrcorner}$에 따르면 각 교과 수업 시간에 ICT 활용 교육이 $10\%$이상 반영되도록 적극 권장하고 있다. 이에 따라 각급 학교에서는 전통적인 학습 지도안과 ICT 활용 교수-학습 과정안의 두 가지 형태를 병행하여 사용하고 있으나 작성 도구와 형식이 다양하여 교사들 상호간의 문서 공유와 재사용성이 떨어지며 웹 상에서 정확한 검색이 어렵다. 본 논문에서는 한국교육학술정보원에서 제시하고 있는 ICT 활용 교수-학습 과정안의 모형을 토대로 공통 DTD를 설계하고 데이터베이스와 연동하여 표준화된 XML 문서를 생성함으로써 교사들 상호간의 공유 및 재사용성을 높이고 정확한 검색이 이루어지도록 하였다. 또한 유선 인터넷 서비스와 동시에 무선 인터넷 환경에서도 WML을 이용하여 모바일 서비스가 가능하도록 구현되어 있어 보다 향상된 교수-학습 환경을 제공할 수 있다.

본 논문에서는 CNN 알고리즘을 사용한 수학 문제 답지 추론 모델에 대한 소개를 다룬다. 현재의 학습 보조 서비스 중에서도 질문에 답하는 서비스들이 흔하지만, 수학 문제에 특화된 이미지 기반 답지 추론 서비스는 부족한 상황이다. 본 논문에서는 MathDataset 클래스를 활용하여 수학 문제 이미지와 정답을 연결하는 데이터셋을 생성하고, CNN 알고리즘을 사용하여 모델을 훈련하는 방법을 제시한다.
