NoC 시스템은 기본적으로 서로 다른 클럭 도메인에서 동작하는 여러 버스 시스템들이 NoC를 통해서 연결되는 것으로 간주할 수 있다. NoC에 다른 버스 인터페이스 IP를 부착하려면 별도의 래퍼를 사용해야 하며, 면적과 지연시간이 추가되는 것이 일반적이다. 본 논문에서는, 추가적인 래퍼의 필요성을 제거하기 위하여, 주어진 버스 인터페이스에 맞는 인터페이스 에이전트 또는 네트워크 인터페이스를 자동 생성하는 방법을 제안한다. 이를 위하여, 한가지 NoC 시스템을 위해 표준적인 패킷 포맷을 정의하였으며, 거기에는 패킷에 대한 라우팅 정보 뿐 아니라, 여러 종류의 버스 프로토콜의 데이터, 주소, 제어 정보도 포함될 수 있도록 정의되었다. 그리고, 인터페이스 에이전트는 표준 패킷 포맷과 특정 버스 인터페이스 프로토콜 간의 변환 작업을 수행한다. 실험을 통해서, PVCI, WISHBONE, AHB, OCP와 같은 몇 가지 버스 인터페이스에 대해 자동생성된 네트워크 인터페이스들 간에, 표준 패킷 포맷을 이용한 데이터 통신이 중요 정보의 손실 없이 잘 이루어짐을 보인다.

In this paper, we propose a simple hardware reporting method for errors in soft-RAID systems of Linux OS. Compared with other reporting methods, the proposed method displays error status intuitively without any additional access process such as log-in process or home-page access. In particular, the server actively displays the error status, so the administrator can take immediate action. In order to confirm the effectiveness of the proposed method, the experimental circuit was constructed and the experimental results showed that the error was actively displayed when an error occurred in the storage device. As such, a soft-RAID system can perform almost the same function as a hardware RAID system, thereby ensuring server data reliability at low cost.

Recent research has seen significant improvements in various object detection and classification models overall. However, the study of object detection and classification in situations where objects are partially obscured remains an intriguing research topic. Particularly in the military domain, unmanned combat systems are often used to detect and classify objects, which are typically partially concealed or camouflaged in military scenarios. In this study, a method is proposed to enhance the classification performance of partially obscured objects. This method involves adding occlusions to specific parts of object images, considering the surrounding environment, and has been shown to improve the classification performance for concealed and obscured objects. Experimental results demonstrate that the proposed method leads to enhanced object classification compared to conventional methods for concealed and obscured objects.

Recently, speech recognition models have been advancing, accompanied by the development of various speech processing technologies to obtain high-quality data. In the defense sector, efforts are being made to integrate technologies that effectively remove noise from speech data in noisy battlefield situations and enable efficient speech recognition. This paper proposes a method for effective speech recognition in the midst of diverse noise in a battlefield scenario, allowing commanders to convey orders. The proposed method involves noise removal from noisy speech followed by text conversion using OpenAI's Whisper model. Experimental results show that the proposed method reduces the Character Error Rate (CER) by 6.17% compared to the existing method that does not remove noise. Additionally, potential applications of the proposed method in the defense are discussed.

The purpose of this study was to evaluate the effects of a nutrition education program as part of health promoting projects in an elementary school. A total of 168 students in the 4th grade were enrolled in the program for 6 months. A self-administered questionnaire was developed to assess nutrition knowledge and dietary habit. Nutrient intakes and body shape perceptions were measured using 24-hour recall method and self-ratings of body shape figures, respectively. The education program was conducted in various ways, focused on healthy dietary behavior, nutrients' roles and sources, and proper body shape perceptions, etc. After the education program, nutrition knowledge and dietary habit were significantly improved. Dietary habit scores were significantly and positively related to nutrition knowledge levels. Body shape perceptions were significantly and properly changed after the program. Dissatisfaction with perceived current body shape and discrepancy between shapes desired and considered healthy were significantly decreased. But girls still indicated a desire to be leaner than shapes which were perceived current and considered healthy. Nutrient intakes were partly improved by the program, but some nutrients, such as calcium, folate, zinc, sodium and niacin, were still remained deficient or excessive. These findings indicate that enhancement of nutrition knowledge is extended to the improvement of dietary habit. In addition, establishment of proper body shape perception is closely related to healthy dietary habits and is required to good nutrition and health.

The computer has become an indispensable tool for animation works. However if you don't understand the characteristics of the computer and its software, you might not have the result satisfying your efforts. The incorrect understanding of image format sometimes causes it. Habitually image formats are selected usually for most of works but there is a distinct difference among those image formats while the efficient usages of them are different from each other. For your more efficient work therefore, you need to identify the characteristics of various kinds of image format used mostly for animation works. First I took a look at the theories of the lossy compression and lossless compression, which are two types of data compression widely used in the whole parts of computer world and the difference between bitmap method and vector method, which are respectably different in terms of the way of expressing images and finally the 24 bit true color and 8 bits alpha channel. Based on those characteristics, I have analyzed the functional difference among image formats used between various types of animation works such as 2D, 3D, composing and editing and also the benefits and weakness of them. Additionally I've proved it is wrong that the JPEG files consume a small space in computer work. In conclusion, I suggest the TIF format as the most efficient format for whatever it is editing, composing, 3D and 2D in considering capacity, function and image quality and also I'd like to recommend PSD format which has compatibility and excellent function, since the Adobe educational programs are used a lot for the school education. I hope this treatise to contribute to your right choice of image format in school education and practical works.

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.
