MANET(Mobile Ad-hoc Network) 환경에서 P2P(peer to peer) 시스템은 중앙 집중식 서버 구조나 고정된 인프라를 활용할 수 없다는 제약 때문에 효율적인 파일 공유 및 검색을 지원하기 어렵다. 본 논문에서는 위치기반 라우팅의 위치 서비스 메커니즘을 사용하는 MANET P2P 파일 검색 프로토콜을 제안한다. 제안하는 시스템에서 참여 노드들은 응용 계층의 파일 색인 테이블과 네트워크 계층의 라우팅 테이블을 통합한 크로스 레이어 테이블을 유지한다. 참여 노드들은 이를 이용해 플러딩(flooding)을 배제한 파일 검색을 수행할 수 있으며 질의에 검색된 파일은 파일 요청 노드의 지리적인 위치를 고려해 선택되기 때문에 최적화된 라우팅 경로를 형성할 수 있다.

Looking at multimedia education contents from a design point of view, the instructor's design model may differ from the child's understanding model due to gap of the instructor's and child's knowledge. This fact implies it impacts the effectiveness of the education contents. The learning efficiency of Korean typography in WBI for children depends on the font-family, line space, font-size, the age of user, the output device such as the monitor, and other various factors. In this paper, we measured and analyzed on readability of Korean typography in WBI for children by reading speed method. The results of experiments show that readability depends on the font-family of typography, age(grade), and sex of children. In detail, "Goolymche" has the shortest time to be read, and girl and the highest grade students of elementary school have shorter time than boy and the lower grade students. Moreover, we consider the elegance of typography in WBI for holding children's interests because they prefer "Yopseoche". We provide some CSSs in WBI for children based on the experimental results, to used in school fields.

Metonymy can be said to be the only language's meaning shifting technique that exists in the domain of a single human thought in order to obtain a transparent cognitive effect. The purpose of this study was to analyze the 'descriptive metonymy' of the advertising content language constructed by the cognitive principle and to find a way to use it in media language education for social and cultural interests and reflection of college students. The metonymy used in advertising media contrasts with the difficulty of the metaphorical interpretation of "opaque and distant" reasoning. Storyboards, mostly focused on human emotions and behaviors, used metonymy's 'transparent and easy meaning shifting technique'. I have found that I can expect the efficiency of media language education that contains the interest and sociocultural interest, self-reflection, and future imagination of college students. Now, there is less need to perform cognitive reasoning for advertisements with ambiguous metaphor techniques. Lastly, in order to produce successful advertising content, we expect to use the language technique of 'narrative metonymy' with warm feelings of humans, and acknowledge the lack of quantitative research and leave it as a task for the next research.

본 연구는 정보기술에 관련된 신문기사의 내용과 성격에 관하여 분석하였다. 동아일보와 조선일보양대 일간지를 88년 1월 부터 92년 12월 까지 5년동안 조사하였으며 총 1551건의 정보기술 관련 기사를 분석하였다. 조사결과를 보면 1988년 부터 1992년 사이에 양대 신문에 나타난 정보기술 관련기사가 점점 더 증가하는 추세를 보였으며 이는 정보화사회의 도래와 함께 정보기술이 우리사회의 여러분야로 확산되고 있음을 잘 보여주고 있다고 하겠다. 기사의 내용은 원격통신, 신제품 개발, 컴퓨터관련 교육, 하드웨어와 소프트웨어의 개발과 유통 등에 관련된 기사가 주류를 이루었으며 그외에 공장자동화, 사무자동화, 가사자동화, 컴퓨터관련 범죄, 데이타베이스, 지역정보화, 멀티미디어 등에 관한 주제가 다루어졌다. 한편, 정보기술 관련기사의 성격은 기존의 신문기사에서 부정적인 기사가 주류를 이루고 있는 것과는 달리 긍정적인 기사가 큰 비중을 차지하고 있는 것으로 드러났다. 이는 정보기술이 비교적 새로운 분야이므로 정보기술의 부정적인 측면보다 긍정적인 측면을 부각시키고 있기 때문인 것으로 판단된다. 그러나 최근의 기사에서는 컴퓨터 사용에 관련된 문제점, 컴퓨터를 이용한 범죄, 개인의 프라이버시 침해 등 부정적인 측면의 문제도 제기되고 있다. 신문기사의 내용분석에 의하면 기업의 업종에 따라 정보기술의 활용면에서도 분명한 차이를 보여주고 있는데 제조업의 경우 기업의 내부 물적활동, 생산활동, 외부 물적활동에 관한 기사들이 많았으며 서비스업종의 경우에는 고객에 대한 협상력을 증가시키는데 관련된 기사들이 많았고, 하드웨어나 소프트웨어 산업의 경우에는 고객에 대한 협상력을 증가시키는 문제와 함께 대체재의 개발에 관련된 기사도 많이 등장하였다.

The aim of this study is to explore the status and tasks of selecting, expanding, and supporting the gifted teachers to efficiently manage the gifted education. This study addresses that the ratio of applications for new teachers is lower and the current teachers are aging in primary school. In addition, it points out that the ratio of new teacher applications and teacher acquisitions compared to the number of teachers hired for middle school were lower. The gifted teachers are basic in their classes and work at regular schools, and they suffer from considerable exhaustion and a lack of time because of other gifted work. As a result of these discussions, it has shown the need for substantial improvement and supplementation such as school hours reduction or reinforcement adjustment, complete support for research society, invitation professional teachers other than current ones, and friday after school classes for the gifted teachers should be encouraged to work passionately. For professional development, if the positive perception and results of gifted education from the interactions between general education and gifted education be formed, and the education programs for gifted teachers be expanded, they will also contribute to the overall improvement in the quality of our education.

In this paper, we propose to present a storytelling education plan for the development of realistic content. The need is emerging in the content industry for realistic content along with technological convergence as development of media technology. This phenomenon is being accelerated by COVID-19. In 2019, the government set up strategies to secure future growth engines, announced "three major innovation strategies" in the content industry, and emphasized "fostering leading realistic content." Realistic content is a content that users can experience directly. It is first-person storytelling that should be dealt with as important as the development of technology in the production of realistic content. In this paper, the results of storytelling classes conducted at the actual educational site are analyzed, and the difference from the first-person perspective commonly used in traditional literary works is described. Through this, we present effective teaching methods that can be used to develop realistic content.
