MANET이 유연성 있고, 자유로운 네트워크로서 주목 받아감에 따라 MANET에서의 Routing 알고리즘이 중요한 논점이 되고 있다. 특히 이동 에드혹에서 각 Node에 대한 관리 방법은 향후 차세대 네트워크의 중요한 부분으로 인식되고 있다. 본 논문에서 연구하고 제안하는 오버레이 멀티캐스트 Routing 알고리즘은 Cluster링 Node의 오버레이ID 생성 및 유지에 관한 알고리즘으로 MANET의 여러 가지 제한 조건 및 조건에 따라 유연성 있게 작용하므로, 현재 많은 연구가 이루어지고 있다. 그러나 기존의 오버레이 멀티캐스트는 일반적인 단일 레이어로 이루어진 Cluster에 한하여 그 알고리즘을 적용하고 있으며, Cluster의 구성 및 유지 또한 Node의 속성 구분에 따른 에너지 등을 고려하지 않고 있다. 본 논문에서 제안하는 OMM은 오버레이 멀티캐스트를 Cluster링 기반의 RODMRP에서 사용하는 멀티레이어 구조에 링크코스트에 따른 Node의 잔여 에너지를 고려하여 적용하였으며, 멀티레이어의 장점과 네트워크의 Life Time을 위한 Node의 오버레이 ID 생성 및 유지에 대한 효율적인 알고리즘을 제안하고 있다

Although digit character recognition has got a significant improvement in recent years, it is still challenging to achieve satisfied result if the data contains an amount of distracting factors. This paper proposes a novel digit character recognition approach using a multi-layer hierarchical model, Hybrid Restricted Boltzmann Machines (HRBMs), which allows the learning architecture to be robust to background distracting factors. The insight behind the proposed model is that useful high-level features appear more frequently than distracting factors during learning, thus the high-level features can be decompose into hybrid hierarchical structures by using only small label information. In order to extract robust and compact features, a stochastic 0-1 layer is employed, which enables the model's hidden nodes to independently capture the useful character features during training. Experiments on the variations of Mixed National Institute of Standards and Technology (MNIST) dataset show that improvements of the multi-layer hierarchical model can be achieved by the proposed method. Finally, the paper shows the proposed technique which is used in a real-world application, where it is able to identify digit characters under various complex background images.

The purpose of this study is to explore the educational effect by developing and applying a decision tree-based artificial intelligence convergence education program. To achieve the purpose of this study, the study was conducted through a three-step process of preparation, development, and improvement. In addition, it consisted of four stages of the creative problem-solving process: 'Understanding the problem', 'Idea search and development', 'realization' and 'evaluation'. In particular, the artificial intelligence convergence education program developed in this study is an unplugged activity that does not include programming. Therefore, it is very noteworthy that artificial intelligence convergence education was implemented in subjects other than technology and home economics education, and information education, which are part of junior engineering education, and practical arts education in elementary education, which is a subject that learns Artificial Intelligence technology including programming during class time. In other words, it shows that AI technology can be integrated and taught in most subjects, not specific subjects and has great significance in that it can utilize the concepts and principles of artificial intelligence technology when teaching the concept of classification, which is included in the curriculum.

Recently, the Ministry of education science and technology announced a revised information and communication technology curriculum, emphasizing aspects of computer science education rather than application of computer softwares. This change would benefit students to stimulate their thinking ability and facilitate creativity learning through in-depth understanding of principles of computer science, compared to the previous curriculum of computer education mainly focused on the skills of utilizing application softwares. Thus, the paper presents the design of a computer education curriculum based on the principles of computer science education, which would lead to trigger constructive ideas for improvements on the subject so that students may experience better education in the area.

This research investigates the availability of information resources for visually impaired students in University libraries in Nigeria; a tool for inclusive University education. A Descriptive survey research design was adopted for the study and a total number of 20 University libraries took parts in the study. A self-constructed online questionnaire was designed and distributed to collect the data from respondents (librarians) using a simple random sampling technique. A total of 45 respondents filled out the online questionnaire, but 40 were valid and useful for analysis. The use of frequency count and percentages method of data analysis was adopted for this research work. The study reveals that most of the University libraries lacked information resources for visually impaired students, it was found that the inclusion of information resources for visually impaired persons will promote inclusive education and librarians' skills. The challenges hindering the availability of information resources to the visually impaired students are insufficient funds for maintenance, erratic power supply and inadequate skills by users, among others. Recommendations were made for the campaign for inclusive education and the provision of information resources for visually impaired students.

With the development of information and communication technology, information literacy and utilization are emerging as basic skills necessary for modern people. Accordingly, information education is becoming a basic literacy education for a nation. Unplugged computing is in the spotlight as a major educational method of information education. The main advantage of unplugged computing is that it is easy to convey basic theories or principles of computer science to students through play activities without the help of special information devices such as computers and tablet PCs. However, studies on student evaluation on unplugged computing have been very insufficient. In this study, students' evaluation standards are developed to maximize the educational effect of unplugged computing. The evaluation standards consist of four areas: participation, interest, satisfaction, and understanding of concepts. The results of this study can be used as a basic study for student evaluation of unplugged computing in the future.
