인터넷 기술을 활용한 클라우드 컴퓨팅 서비스의 확산에 따라 개인정보 유출 위험과 정보에 대한 통제가 불가능해질 수 있는 보안 위협이 증가되고 있으나, 현재 클라우드 컴퓨팅 서비스 제공자는 개인정보보호에 대한 충분한 보호조치를 서비스 이용자에게 제공하지 못하고 있는 상황이다. 본 논문에서는 클라우드 컴퓨팅 서비스에 대한 개인정보보호 고려 사항을 살펴보고, 클라우드 컴퓨팅 서비스 환경에서의 개인정보보호 위협에 대응하는 방안을 제안한다.

Since Richard Feynman presented the concept of quantum computers, quantum computing have been identified today overcoming the limits of supercomputing in various applications. Quantum hardware has steadily developed into 50 to hundreds of qubits of various quantum hardware technologies based on superconductors, semiconductors, and trapped ions over 40 years. However, it is possible to use a NISQ (Noisy Intermediate Scale Quantum) level quantum device that currently has hardware constraints. In addition, the software environment in which quantum algorithms for problem solving in various applications can be executed is pursuing research with quantum computing software such as programming language, compiler, control, testing and verification. The development of quantum software is essential amid intensifying technological competition for the commercialization of quantum computers. Therefore, this paper introduces the trends of the latest technology, focusing on quantum computing software platforms, and examines important software component technologies.

The purpose of the study is to develop effective teaching methods to strengthen the major learning capabilities of electronic engineering learners through inquiry learning using computing thinking ability. To this end, first, in the electronic engineering curriculum, we performed teaching-learning through an inquiry and learning model related to mathematics, probability, and statistics under the theme of various majors in electronic engineering, focusing on understanding computing thinking skills. Second, an efficient electronic engineering subject inquiry class operation using computing thinking ability was conducted, and electronic engineering-linked education contents based on the components of computer thinking were presented. Third, by conducting a case study on inquiry-style teaching using computing thinking skills in the electronic engineering curriculum, we identified the validity of the teaching method to strengthen major competency. In order to prepare for the 4th Industrial Revolution, by implementing mathematics, probability, statistics-related linkage, and convergence education to foster convergent talent, we tried to present effective electronic engineering major competency enhancement measures and cope with innovative technological changes.

The purposes of the study were to investigate the participation of artists in paper circuit computing learning and to conduct an in-depth study on the formation and development of practical knowledge. To do this, we selected as research participants six artists who participated in the learning program of an art museum, and used various methods such as pre-open questionnaires, participation observation, and individual interviews to collect data. The collected data were analyzed based on community of practice theory. Results showed that the artists participated in the learning based on a desire to use new technology or find a new work production method for interacting with their audiences. In addition, the artists actively formed practical knowledge in the curriculum and tried to apply paper circuit computing to their works. To continuously develop the research, participants formed a study group or set up a practical goal through planned exhibitions. The results of this study can provide implications for practical approaches to, and utilization of, paper circuit computing.

The competition for technological supremacy is unfolding in the high-tech field, and quantum computing can be determinant for economic and security ripple effects. The United States and China, leaders in quantum computing, have developed this field through adequate policies. The United States has fostered quantum computing through government policies and competition among private companies, while China has secured world-class technology through large-scale government investment and attracting foreign talent. In quantum computing, securing talented people is essential to guarantee independent technology development regarding academic attributes and security. We analyze quantum computing policies in the United States and China on a timeline and determine their policy trends. In addition, the policies for securing talent in these countries are reviewed, and the policy effects are compared based on literature analysis. Through the analysis of policy cases between the United States and China, bilateral policy implications for Korea are delineated.

To address the problems of large system overhead and low timeliness when dealing with task scheduling in mobile edge cloud computing, a task scheduling and resource management strategy for edge cloud computing based on an improved genetic algorithm was proposed. First, a user task scheduling system model based on edge cloud computing was constructed using the Shannon theorem, including calculation, communication, and network models. In addition, a multi-objective optimization model, including delay and energy consumption, was constructed to minimize the sum of two weights. Finally, the selection, crossover, and mutation operations of the genetic algorithm were improved using the best reservation selection algorithm and normal distribution crossover operator. Furthermore, an improved legacy algorithm was selected to deal with the multi-objective problem and acquire the optimal solution, that is, the best computing task scheduling scheme. The experimental analysis of the proposed strategy based on the MATLAB simulation platform shows that its energy loss does not exceed 50 J, and the time delay is 23.2 ms, which are better than those of other comparison strategies.
