  • The purpose of this study is to explore the differences between Korea and Japan in terms of the effects of student- and school-level ICT-related factors on computer-based problem solving ability in PISA 2012 achievement results. PISA 2012's computer-based problem solving assessment included 5,033 students from 156 schools in Korea and 6,351 students from 191 schools in Japan. A 2-level hierarchical linear model (HLM) was employed to analyze data. Both of Korean and Japanese students, students with the earlier use of computer and the Internet, higher socioeconomic background and higher openness to problem reported better problem solving scores than their counterparts. Also, accessibility to ICT equipment provided by home or school was found to be a negative effect on problem solving in both countries. Differences in the effects of purposes and attitudes for ICT use, teacher-student relationship, and creative out-of-school activities on problem solving ability were found between two countries.

  • In this paper, we attempted to provide the bases of effective educational programs for fostering ICT competencies of gifted students in science. For this purpose, we tried to answer the questions like 'What are the ICT core-competence for gifted students in science?' and 'How can we educate those competencies effectively?' We started by reviewing existing studies on ICT competencies for talented people in future society and then adopted one[6] as the basis for further validation. We tried to work with as many G/T experts as possible, and decided to use the online survey methodology because the experts are scattered all over the country. The survey was sent to the corresponding person who is in charge of G/T education in each area, and then e-mailed to G/T experts in that area. Through these procedures, three hundred four(304) G/T experts from all around the country participated in this survey. The results showed the followings: (1) G/T experts agreed with the importance and necessity of ICT competencies for gifted students in science; (2) G/T experts agreed with the validity of three core ICT competencies, which are 'knowledge and skills competence, creativity competence, and characteristic competence,' for gifted students in science; (3) G/T experts agreed with the validity of educational goals, which are suggested for fostering each ICT core-competence of gifted students in science; and (4) G/T experts regarded 'product-oriented education' and 'ICT device-oriented education' as important and effective types of education programs for fostering ICT competencies of gifted students in science.

  • Depression and mental illness across all age groups, and steady increasing in suicide rate are our major social problems which cause dramatically decreasing government competitiveness. While Korean government has implemented various policies to improve mental health and prevent suicide, it faces revealing issues in progress on implementation and referral management systems. The current research examined domestic and foreign cases to understand the actual status and directivity of ICT convergence plan in terms of mental health. The United States and the United Kingdom have provided convergent ICT service, telepsychiatric care to senior citizens in rural areas, children and adolescents, socially disadvantaged class, etc. In Korea, emergency-notice devices are installed to prevent suicide for single elderly people, and diverse mobile health devices are developing to cure depression and Alzheimer's disease. ICT convergent mental health care service is needed to save socioeconomic costs and realize universal welfare for an aging society. Social consensus on sharply conflict issues, medical law and medical devices about telepsychiatry service, effectiveness studies on users' unique psychiatric characteristics by life cycle, and region-specialized strategies for the least densely populated rural regions with lower access to medical care should be considered.

  • Existing environmental measuring devices mainly focus on electromagnetic wave and eco-friendly product certification and durability test, and sensor reliability verification and verification of measurement data are conducted mainly through sensor performance evaluation through type approval and registration, acceptance test, initial calibration, and periodic test. This platform has established an ICT-based environmental monitoring sensor reliability verification system that supports not only performance evaluation for each target sensor, but also a verification system for sensor data reliability. A sensor board to collect sensor data for environmental information was produced, and a sensor and data reliability evaluation and verification service system was standardized. In addition, to evaluate and verify the reliability of sensor data based on ICT, a sensor data platform monitoring prototype using LoRa communication was produced, and the test was conducted in smart cities. To analyze the data received through the system, an optimization algorithm was developed using machine learning. Through this, a sensor big data analysis system is established for reliability verification, and the foundation for an integrated evaluation and verification system is provide.
