하나의 문화권에 들어가 있는 콘텐츠가 다른 나라로 진입할 때 가로막는 것이 있다. 바로 문화장벽이다. 이 문화장벽에 들어가 있는 것에는 언어도 있을 것이고, 사회적 관습차이, 그 나라의 국가관 같은 다양한 문화적 차이가 있다. 전세계적으로 이 문화장벽이 가장 낮은 곳이 바로 북한이다. 최근 북한산 혹은 남북이 공동개발한 디지털콘텐츠가 속속 선보이면서 이에 대한 관심이 높아지고 있다. 북한 디지털콘텐츠 산업의 현황을 살펴봤다.

The college students who have relatively weak academic background feel more difficult in learning programming language grammars and programming skills in introductory course. At the end of semester, most of students had the negative attitude to programming and only a few students could write the programs for the given problems because they spent most of time to learn grammars instead of learning problem solving skills and logics. In this study, we propose to use Scratch in introductory programming course to help students to understand grammars and problem solving skills. It's necessary to educate first-time programmers how to solve the problems before they learn grammars of the programming language in their first programming language course. This paper shows that Scratch allows students not only to learn problem solving skills in programming but also to motivate students themselves in the class.

Instructive lessons in the language classrooms are extremely constrictive to language learners in improving their English skills, thus, the use of technology in education plays an important role in a language classroom. Results of language proficiency improvement of the learners vary depending on the extent of supplementary materials offered by the internet delivered to the learners. The purpose of the present study is to explore and propose a new approach of language acquisition offered by the internet. This study presents effective methods of using the internet in carrying out the written work. In this paper, we show that the relationship between participation of the learners in the class activities and improvement of English writing skills are mutually proportional.

Various linguistic knowledge resources are required in order that machine can understand diverse variation in natural languages. This paper aims to devise an automatic construction method of linguistic resources by reflecting characteristics of online contents toward continuous expansion. Especially we focused to build NE(Named-Entity) dictionary because the applicability of NEs is very high in linguistic analysis processes. Based on the investigation on Korean Wikipedia, we suggested an efficient construction method of NE dictionary using the syntactic patterns and structural features such as metadatas.

신호처리의 목적은 신호를 변형하여 우리가 원하는 형태로 만드는 것으로 신호를 변환시키는 장치 즉 시스템이 신호에 응답하여 다른 형태의 신호를 만들어 내는 것을 신호처리라 한다. 현재는 음성신호 처리시에 대부분 입력시호인 아날로그 신호(Analog Signal)를 표본화(Sampling)하고 양자화(Quantizing)하여 디지털 신호(Digital Signal)로 변환한 후 필요한 신호처리를 수행한다. 디지털 신호를 처리하므로써 정확성, 신뢰성, 처리속도를 증가시키게 되고 전자시스템(Electronic System)의 크기를 줄일 수가 있다.

This paper introduces noise masking algorithm for 64 channel digital hearing aid. 125 Hz spectral resolution is maintained for 64 channels from 125 Hz to 8000 Hz. The same spectral masking processing effects as the cochlea are considered and applied for the present hearing aid noise reduction processing algorithm. Theoretical algorithm has been ported into assembler language program software and been embedded into a DSP IC chip for the digital hearing aid. Some parts of noise masking software program code are explained, and the results of the real-time noise reduction are verified by electro-acoustic measurements.

In this paper, we are implemented the courseware targets to the integrated a digital system analysis, a design theory, and a hardware description language training and a logic analysis. This paper consists of two subjects. One is that the learning of a digital system analysis, that of a design theory, and the training of a hardware description language is simultaneously performed. The other is that the experiment of courseware. To learn the hardware description language, the explanation using sound or moving images, setting-up of a simulation or a synthesis program, and simulating are executed on a courseware. And also, we proposed an integrated systems for the hardware description language and a logic synthesis. Also, The reliablity of the tool was verified to be preyed an efficient operation of an implemented digital system courseware tool by korea computer research association.

Non-verbal communication cues seem to be increasingly used in social media, such as emoticon, like, follow, etc. A Q methodology study is conducted to explore this phenomenon. Via a series of focus group activities with Facebook heavy users, 34 Q statements concerning online non-verbal communication cues are derived. Different Facebook users conduct Q sorts of these statements based on frequent use basis. Analysis of Q sort result reveals three distinctive usage patterns of non-verbal communication cues in Facebook: 'safe distance keeping' type, 'observing hermit' type and 'fully dedicated aficionado' type. Discussions are made concerning different components of non-verbal communication cues utilized in these groups, respectively, which can provide a theoretical basis for social media design.

OpenCV is a programming language used in digital image processing and computer vision. In this study, look at media arts made using OpenCV programming language and find out about the utilization possibilities. To this end, the first, look at OpenCV functions that are frequently used in media art, the examples of utilizing the functions. The second, discuss media arts using OpenCV. focused on the OpenCV functions, programming language for an production of media art. The third, analyze features of media arts using OpenCV, mainly focused on the functions and programming languages. The study may provide guidance to the artists to produce a media art using the OpenCV or programming language.
