A student's school records should be utilized not only as data for storage and a guide for entrance into future schools, but also as data for evaluating the student's school life whenever their parents or the student wants to. This study is based on the necessity of the communication between school and home by means of information communicative media, and the duty of faculty to provide the parents with information regarding the student's educational growth. For this purpose, a system was developed and discussed to permit both the students and their parents access to a database of the students' school records which were stored in the School Total Information Management System. This system had been promoted as part of an education information program, so that both students and parents could read it individually at any time.

액세스망 기술 분야는 초고속 정보통신 서비스를 제공하기 위하여 유·무선 전달 매체 처리기술, 액세스망 구성 방식 기술, 기존 인프라를 이용하는 고도의 DSL기술 등이 복합되어 사업자의 망 구축 여건에 따라 다양한 형태로 실현되고 있다. MAIN1)은 기존 동선상에서 전화 및 데이터 서비스는 물론 광대역서비스 제공을 위해 VDSL기술을 채용하며, 망 구성방식으로는 ATM/SDH 또는 ATM/PON 기반으로 FTTx 방식의 통합 액세스망 플랫폼이다. 그러나 액세스망은 다수 망사업자와 서비스사업자 환경과 공중망과 사설망이 혼재하며, 새로운 요소기술이 복합되는 망 영역이므로 소요장치의 OAM 뿐만 아니라 망관리에 대한 체계적인 OA&M이 요구되고 있다. 액세스망의 OA&M은 비용 효과적인 액세스망 실현과 실제 망 운용비용과는 상호 상반된 관점을 가진다. 본 논문은 다양한 형태의 액세스망에 대해 통합 관점의 망 관리와 시스템 관리를 위한 체계적인 OA&M 정립을 목적으로 한다. 이를 위하여 통합 엑세스망 플랫폼에 대한 망관리 설계 접근 방법 및 고려사항에 대해 논하고, MAIN의 관리 구조 모델을 제시한다. 또한 MAIN 하드웨어 구조에서 NEL 시스템의 운용관리 및 소요기술에대한 OAM 기능과 망관리 기능 구현을 통하여 MAIN 엑세스망의 OA&M 실현 구조를 조명 함으로서 관련 액세스망 OA&M 구현 시 기본 참조 모델로 제안한다.

지난 4월4일 고성 산불로 사망자 2명과 부상자 1명, 가옥 500여 채, 삼림 1757ha가 불에 탔다. 강원 산불에 이어 영덕지진 등에서 늑장대응을 보여준 재난방송시스템에는 많은 국민들에게 실망감을 안겨주었다. 재난방송 주관방송사인 KBS는 물론, MBC, SBS의 경우도 재난방송시스템에 관련 된 측면에서 본다면 아직 이웃나라 인 일본에 비해서는 매우 열악한 형편이다. 그럼에도 불구하고 점점 대형화, 다발화 하는 재난발생에 대응하기 위해서는 국가적인 차원에서도 특단의 조치가 필요하다. 미국의 경우는 차세대 재난정보 전달체계인 IPAWS(Integrated Public Alert and Warning System)를 개발해 지상파뿐만 아니라, 케이블TV, SNS 등 다양한 매체를 통해 재난정보를 신속하게 전달하고 있다. 일본도 이와 유사한 재난경보전달시스템인 J-Alert를 개발해 2020년까지는 '재난 약자 제로(Zero)시대'를 목표로 구현하고 있다. 우리나라는 지난 아현동 KT 화재사건에서도 경험했듯이 통신이 먹통이 되는 통신블랙아웃도 경험했다. 따라서 대형재난발생 시는 신속한 재난경보전달시스템이 재난피해를 줄일 수 있는 가장 중요한 생명줄이 될 수 있다. 미국이나 일본의 경우는 재난방송전달시스템을 관련법령으로 제도화 하고 있다. 특히, 일본에는 재난에 관한 모법이라고 할 수 있는 (1)"재해대책기본법"이 있는데, 이는 재해로부터 국토, 국민의 생명과 재산을 보호하기 위한 기본법으로 규정되어 있다. 그 밖에도 (2)방송법 (3)대규모지진대책특별 조치법 (4)국민보호법 (5)소방조직법 (6)수해방지법 등으로 규정하고 있다. 과거 일본도 우리나라와 같이 대형 산불이 잦았으나 요즘은 소형 산불만 발생하는 추세다. 이는 NHK가 보유한 700여 대의 로봇카메라와 전 국토를 샅샅이 감시하는 CCTV 덕택이다. 또한, NHK 보도국의 '기상 재해센터'는 재난에 대비해 40여 명의 전문 인력이 24시간 대응체제를 갖추고 있다. 나아가 NHK는 전국 12개의 거점지역에 헬리콥터 15대를 배치하여 신속하게 취재하고 있다. 이 뿐만 아니라, 46개의 지역방송국을 7개의 거점방송국으로 분할하여, 거점방송국마다 40여명의 카메라맨을 상주시켜 언제든지 재난을 취재할 수 있도록 하고 있다. 세계 각국에서 사용하고 있는 방송 주파수는 공공재(公共材)다. 국제전기통신연합(ITU : International Telecommunication Union)으로부터 주파수를 할당받아 사용하고 있기 때문에 주파수에 관한 사용 권한은 각국의 국민 모두에게 있다. 그러나 효과적인 주파수 활용을 전제로 정부가 일정한 자격을 갖춘 방송사업자에게 일시적으로 주파수 사용권을 위임하고 있다. 따라서 일본 정부도 국가적인 위기나 대형 재난발생으로 국민들의 생명과 재산이 위협받고 있을 때에는 공공재인 주파수를 즉시 재난방송으로 사용할 수 있도록 <재해대책기본법 제6조>와 방송법 제108조에 규정하고 있다.

Currently, the domestic early warning system is issued differently for each disaster, and is operated independently by relevant organizations from central government to local governments. Representative domestic disaster warning systems include disaster broadcasting using CBS(Cell Broadcasting Service) and DMB(Digital Multimedia Broadcasting) Automatic Emergency Alert Service, DITS(Disaster Information Transform System) transmitted and displayed on TV screens, automatic response system, automated rainfall warning system, and disaster message board. However, due to the difference in the method of issuing each emergency alert at the site of an emergency disaster, the alerts are issued at different times for each media, and the delivered content is also not integrated. If these systems are integrated, it is expected that damage to people's property and lives will be minimized by sharing and integrated management of disaster information such as voice, video, and data to comprehensively judge and make decisions about disaster situations. Therefore, in this study, we present a plan for the integration of the disaster warning system along with the analysis of the operation status of the domestic early warning system.

Due to the recent advances in computing, communication and micro-electromechanical technology, Wireless Sensor Networks (WSNs) applications have been extended from military to many commercial areas such as object tracking, wire detection, and vehicular sensor networks. In some applications bursty data from many sensor nodes may be generated and the generated data from the monitoring area may be sent in a limited time to the final destination, sink node. In this paper, we present a BTF-MAC protocol adequate for WSNs applications in which bursty data packets are required to be transmitted in a limited time. The BTF-MAC is a synchronous duty-cycle MAC protocol and uses a slot-reserved and operational period extension mechanism adapted to the traffics. Our numerical analysis and simulation results show that BTF-MAC outperforms other related protocols such as DW-MAC and SR-MAC in terms of energy consumption and transmission delay.

Nowadays, 'Interaction' is discussed not only in the multimedia field but also as a topic of daily life at the various viewpoints. And as the permmited limit of Interaction by Mutimedia Technology and audiovisual function is getting more activated, It is the time for us to have new understanding of a 'POSTER'. The Poster, as a one-sided information transmission media till now, is faced with its limitation in transmitting messages due to its unconformity between satisfaction of receiver' sdesire for information and installation space. This fact speaks for need of study about Digital Poster as an alternative communication method, and activation of Digital Poster Design Field. Therefore, I would like to present Design process and Examples by using Digital Poster for Maximizing the Communication Effect. And I expect the activation of Digital Poster Field by studying the possibility of development and various method of practical use of digital posters through presenting the examples.

With the advent of new media era we are living in the world of motion picture image is not an exaggeration. With the development of the mass media with images and moments that passed the day feeling like part of it is communication. In this era a sensual and shapeable image more than the logical and realistic thinking may be passed. In the act of seeing a moving image, prior to linguistic and conceptual meaning, color and screen configuration delivery and formative element in the change they produce is first recognized. Particular kind of video animation having the narrative structure, this territory effect greatly. the film even more significant effect on the area and linking the image of the scene transitions in the scheme also features a simple means of natural communication functions are being expanded. These transitional effects provide visual pleasure from a simple transition traditional methods. And In terms of narrative functions performed to help a narrative flow of availability, visual representation should continue.

The purpose of this study is to analyze the information behavior of so-called "MZ Generation" users who are going to be the main information users of the continuously and radically changing scientific information environment due to the advent of various types of information media and rapid increment of digital information resources. Especially, the characteristics of MZ generation is investigated through questionnaire asking questions about their use of contents platforms, and online resources for everyday life information and scholarly information, and their way of producing, responding, and sharing information contents. The results show that they use YouTube most as the contents platform, prefer Naver as their everyday life information source, and use Google as the main scholarly information source. Their main purpose of using the content platform is to search for everyday life information rather than scholarly or professional information, and they are actively producing information, mostly to keep records of their everyday lives.

Image is the one of the media that satisfy the wants of people. A motion graphics is a new media stimulating not only a visual but also a hearing of people, and has gained attention by an important emotion communication way that communicates the sound and the visual messages to the audience. In this paper we study on what feelings the motion graphics used on the stage background communicates to the audience, and what its effects and efficiencies are. Because it is not generalized to apply the motion graphics to the stage background, the range of the study can't help being limited. However, recently during two or three years, the use of the motion graphics is increasing more and more, and we expect that its utilization is more expanded.
