  • 본 논문에서는 제한된 자원을 가진 보드에서 딥러닝 기반 검출기 구축에 대한 실현 가능성에 대해 논의한다. 많은 연구에서 고성능 GPU 환경에서 검출기를 평가하지만, 제한된 연산 자원을 가진 보드에서의 평가는 여전히 미비하다. 따라서 본 연구에서는 검출기를 파싱하고 최적화하는 것으로 보드에 딥러닝 기반 검출기를 구현하고 구축한다. 제한된 자원에서의 딥러닝 기반 검출기의 성능을 확인하기 위해, 여러 검출기를 다양한 하드웨어 자원에서 모니터링하고, COCO 검출 데이터 셋에서 On-Board에서의 검출 모델과 On-GPU의 검출 모델을 mAP, 전력 소모량, 실행 속도(FPS) 관점으로 비교 및 분석한다. 그리고 군사 분야에 검출기를 적용한 효과를 고려하기 위해 항공 전투 시나리오를 고려할 수 있는 열화상 이미지로 구성된 자체 데이터 셋에서 검출기를 평가한다. 결과적으로 우리는 본 연구를 통해 On-Board에서 모델을 실행하는 딥러닝 기반 검출기의 강점을 조사하고, 전장 상황에서 딥러닝 기반 검출기가 기여할 수 있음을 보인다.

  • E-Learning is widely introduced with cyber universities in Korea from 2001 whencyber universities were first authorized by the Ministry of Education and Human Resource Development. E-learning amplified by cyber university gave a big impact in the campus based university which became the cause for the educational paradigm shift. The changes of status of cyber university shows important trend in college education which was analyzed by enrollment rate, types of cyber university, demography, and study areas. The enrollment rate of cyber universities is ever since 2001 and variety of study areas gives popularity to students. The demography of students is as expected older than traditional students. Female students at the cyber university outnumbered that at campus based university in Korea. For analyzing the trend of e-learning in Korea, there were studies twice in 2001 May-June from 213 faculty members and staff, 630 students and in 2004 May-June with 401 students. Most of e-learning students tent to spend less time yet, students feel more burden with e-learning. Professors tend to load more materials for the e-learning in 2001but in 2004 study, the difference no longer exists. Professors and students feel the academic achievement through e-learning is not as good as from the traditional classes. Difficulties for e-learning in 2001 were the lack of administrative information but in 2004, boring contents and lack of instructional strategies for e-learning. Technical problems still do exist but less serious. Suggestions for e-learning are blended learning, online students prefer video streaming with their own lecturer, new definition of instructor is needed, professional development for content development and online instruction is needed, success story of online learning should be encouraged, guidance for online students needed. The cyber university experiencegave a positive impact on the traditional universities such as rethinking the roles of universities, the quality control of classes, professional development, student oriented educational service of e-learning pedagogy.

  • Current research on Internet of Things (IoT) has primarily addressed the means to enhancing smart resource allocation, automatic network operation, and secure service provisioning. In particular, providing satisfactory security service in IoT systems is indispensable to its mission critical applications. However, limited resources prevent full security coverage at all times. Therefore, these limited resources must be deployed intelligently by considering differences in priorities of targets that require security coverage. In this study, we have developed a new application of Cognitive Radio (CR) technology for IoT systems and provide an appropriate security solution that will enable IoT to be more affordable and applicable than it is currently. To resolve the security-related resource allocation problem, game theory is a suitable and effective tool. Based on the Blotto game model, we propose a new strategic power allocation scheme to ensure secure CR communications. A simulation shows that our proposed scheme can effectively respond to current system conditions and perform more effectively than other existing schemes in dynamically changeable IoT environments.

  • Scheduling plays a dynamic role in cloud computing in generating as well as in efficient distribution of the resources of each task. The principle goal of scheduling is to limit resource starvation and to guarantee fairness among the parties using the resources. The demand for resources fluctuates dynamically hence the prearranging of resources is a challenging task. Many task-scheduling approaches have been used in the cloud-computing environment. Security in cloud computing environment is one of the core issue in distributed computing. We have designed a deep learning-based security model for scheduling tasks in cloud computing and it has been implemented using CloudSim 3.0 simulator written in Java and verification of the results from different perspectives, such as response time with and without security factors, makespan, cost, CPU utilization, I/O utilization, Memory utilization, and execution time is compared with Round Robin (RR) and Waited Round Robin (WRR) algorithms.

  • In this paper, we propose a real-time drone-based violent protest detection system. Our proposed system uses drones to detect scenes of violent protest in real-time. The important problem is that the victims and violent actions have to be manually searched in videos when the evidence has been collected. Firstly, we focused to solve the limitations of existing collecting evidence devices by using drone to collect evidence live and upload in AWS(Amazon Web Service)[1]. Secondly, we built a Deep Learning based violence detection model from the videos using Yolov3 Feature Pyramid Network for human activity recognition, in order to detect three types of violent action. The built model classifies people with possession of gun, swinging pipe, and violent activity with the accuracy of 92, 91 and 80.5% respectively. This system is expected to significantly save time and human resource of the existing collecting evidence.

  • With an increase in the relevance of next-generation integrated networking environments, the need to effectively utilize advanced networking techniques also increases. Specifically, integrating Software-Defined Networking (SDN) with Multi-access Edge Computing (MEC) is critical for enhancing network flexibility and addressing challenges such as security vulnerabilities and complex network management. SDN enhances operational flexibility by separating the control and data planes, introducing management complexities. This paper proposes a reinforcement learning-based network path optimization strategy within SDN environments to maximize performance, minimize latency, and optimize resource usage in MEC settings. The proposed Enhanced Proximal Policy Optimization (PPO)-based scheme effectively selects optimal routing paths in dynamic conditions, reducing average delay times to about 60 ms and lowering energy consumption. As the proposed method outperforms conventional schemes, it poses significant practical applications.

  • 학교도서관은 교사와 학생들의 교수·학습활동을 지원하고, 학교의 교육과정 전개에 이바지할 수 있어야 한다. 최근, 교육부가 추진하고 있는 자기주도적 학습은 자료중심을 통하여 학생들에게 문제해결능력을 길러주자는 것이다. 자료중심교육은 학교도서관을 떠나서 생각할 수 없는 문제이다. 모든 도서관중에서 가장 기본적인 학교도서관은 정부의 제도적, 행정적인 뒷받침이 없으면 발전할 수 없는 특성을 가지고 있다. 그 동안 정부당국의 무관심과 입시위주의 교육 때문에 거의 빈사상태에 있는 실정이다. 따라서, 학교도서관 관계법령을 개정하여 제도적으로 정착시켜야한다. 어떠한 제도나 조직의 발전은 결국 사람의 문제로 귀결된다고 보아야 한다. 아무리 좋은 법령을 만들고 제도적 장치를 마련해 두어도 행정적인 지원과 뒷받침이 없으면 그 제도나 조직은 발전할 수 없다. 그 조직에 대한 관계기관의 애정어린 관심과 발전에 대한 강력한 의지가 있어야 한다.
