Due to recent development in mobile devices, the mobile device utilization and many related applications have been increasing. Most of initial applications on mobile devices just showed simple information, but now they processes huge data. However, smart devices have certain limitations in processing massive data. Especially, if the size of data increases, the speed of data processing adversely decreases, so the performance of programs also decreases. If hardware specification of the mobile devices is not enough to handle it, response time will be drastically delayed. To overcome these drawbacks, most of application running on mobile devices communicate with their servers to manage data. XML is a proper language for data communication to send and receive data between servers and mobile devices, because it defines rules of document's format and it is a textual data format and small-sized language. However, mobile devices have limitation such as memory, CPU and wireless network to process huge data and XML also takes a lot of time to communicate with servers and devices and handle data, so it could be overhead in service time. Binary XML is an alternative of performance improvement in data processing, which has XML's benefits and minimizes the XML size by binary coding. However, most of binaryXML which are used on applications don't fit on mobile applications. In this paper, we surveyed many kinds of binaryXML, compared merits and demerits to find a binaryXML for mobile applications. We propose how to use binary XML and implemented an electronic attendance system using binary XML to overcome the limitation of XML and to reduce the load of data communications between servers and devices.

Objective: This study aims to investigate whether science teaching attitude of early childhood teachers mediates the relationship between the professional learning environment of institutions and their intention to accept artificial intelligence (AI) technology, and whether the experience of using smart and digital devices moderates the effect of science teaching attitude. Methods: An online survey was conducted targeting 118 teachers with more than 1 year of experience in kindergarten and day care center settings. Descriptive statistical analysis, correlation analysis, and The Process macro model 4, 14 were performed using SPSS 27.0 and The Process macro 3.5. Results: First, the science teaching attitude of early childhood teachers served as a mediator between the professional learning environment of institutions and teachers' intention to accept AI technology. Second, the experience of using smart and digital devices was found to moderate the effect of teachers' science teaching attitude on their intention to accept AI technology. Conclusion/Implications: This results showed that an institutional environment that supports teachers' professionalism development and provides rich experience is crucial for promoting teachers' active acceptance of AI technology.

Currently, the CCDs are widely used in astronomical observations either in direct imaging use or spectroscopic mode. However according to the recent technical advances, new large format CCDs are rapidly developed which have better performances with higher quantum efficiency and sensitivity. In many cases, some microprocessors have been adopted to deal with necessary digital logic for a CCD imaging system. This could often lack the flexibility of a system for a user for to upgrade with new devices, especially if it is a commercial product. A new design concept has been explored which could provide the opportunity to deal with any format of devices from any manufactures effectively for as tronomical purposes. Recently available PLD (Programmable Logic Devices)technology makes it possible to develop such digital circuit design, which can be integrated into a single component, instead of using micrprocessors. The design concept could dramatically increase the efficiency and flexibility of a CCD imaging system, particularly when new or large format devices are available and to upgrade the performance of a system. Some variable system control parameters can be selected by a user with a wider range of choice. The software can support such functional requirements very conveniently. This approach can be applied not only to astronomical purpose, but also to some related fields, such as remote sensing and industrial applications.

홈 네트워크는 가정 내의 가전기기들이 모여 하나의 네트워크를 이루는 것으로 가전기기들의 발전함에 따라 확장되어 가고 있으며, 또한 디지털 콘텐츠의 수도 꾸준히 증가하고 있다. 그러나 콘텐츠 가전기기 사이에 상호 운영성 부족으로 디지털 콘텐츠의 지속적인 저작권 보호가 힘들 뿐 아니라, 가전기기 간에 콘텐츠 이동을 위해서는 DRM 서버로부터 라이선스를 다시 재발급 받아야 한다. 따라서 본 논문에서는 홈 네트워크 안에서 디바이스 상호 인증을 통해 콘텐츠를 다른 디바이스로 자유롭게 이동 할 수 있는 프레임워크를 제안하며, DRM 서버의 라이선스 관리 부담을 줄이고 외부의 사용자가 홈 네트워크에 접근하더라도 사용자를 인증을 통해 콘텐츠 사용이 가능한 시스템을 제안한다.

We introduce, in this paper, a novel approach of protection mechanism for data which are transmitted not only between the networked devices but also between the digital media devices. As the devices are getting more powerful and more storage capacity, they can process the encoded/encrypted data autonomously. However, all devices must know the secret key that used to encrypt data, and also use secure method to distribute that key. Moreover, there are no protection mechanisms supporting end-to-end copy protection which result in the fact that the data passed through various devices can be manipulated or captured. Therefore, we propose a RFID-based key distribution and protection mechanism to resolve these problems.

SNMP는 네트워크 장비들을 관리하기 위한 표준 프로토콜로서, 확장성, 정보관리, 인증, 암호화, 접근 제어 등과 같은 우수한 장비 관리기능을 제공한다. 그러나 상황적응형 서비스를 제공하기 위한 제어 기능을 갖는 디지털 컨버전스 장비들을 통합 관리하기에는 제어기능이 취약하며, SNMP 통신 메시지의 길이에 제약이 있다는 단점이 있다. 이러한 문제점을 해결하기 위하여, 본 논문에서는 제어기능을 가진 디지털 컨버전스 장비들을 통합 관리하기 위한 확장된 SNMP를 제안한다. 확장된 SNMP는 다양한 디지털 컨버전스 장비들을 효과적으로 제어하기 위해 SNMP 엔진에 DDS (Device Driver Subsy stem)를 추가하고 CADM (Control Agent Driver Model)을 정의하여 그 구조를 개선하였다. 따라서 설정과 제어 구분의 모호성을 해결하였고, 추상화된 인터페이스를 지원함으로써 SNMP 어플리케이션이 장비를 쉽게 제어할 수 있도록 하였다. 또한 SNMP 통신 메시지 길이의 제약을 받지 않는 세 개의 SNMP 명령어를 추가함으로써 용량이 큰 고수준의 데이터도 전송이 가능하도록 하였다.

With the recent spread of digital content, more people have been watching the digital content of TV programs on their PCs or mobile devices, rather than on TVs. With the change in such media use pattern, genres(types) of broadcast programs change in the flow of the times and viewers' trends. The programs that were broadcast on TVs have been released in digital content, and thereby people watching such content change their perception. For this reason, it is necessary to newly and differently classify genres(types) of broadcast programs on the basis of digital content, from the conventional classification of program genres(types) in broadcasting companies or relevant industries. Therefore, this study suggests a plan for newly classifying broadcast programs through using machine learning with the log data of people watching the programs in online media and for applying the new classification. This study is academically meaningful in the point that it analyzes and classifies program types on the basis of digital content. In addition, it is meaningful in the point that it makes use of the program classification algorithm developed in relevant industries, and especially suggests the strategy and plan for applying it.
