The study's purpose is to present model for constructing of media education's curriculum. The concept and goal of media education have changed by various media education's paradigm historically. Also this changed the content and the goal of the media education. Curriculum model of media education is various by the nation. AS so the study analyzed the media education's curriculum model to be applying in USA, United British, German, Australia, Canada. Through this, the model for constructing of media education' curriculum is presented. The curriculum model helps to be executed systematically media education in Korea. According to the result, The model is composed of the goal and content. The goal of media education is composed of media knowledge, media appreciation, media analyze, media production. The content of media education is composed of Media, Text, User.

This study is for empirical analyzing the ethical contents in using social media, such as what kind of ethical responsibility do the teenage users have, how do they recognize the ethical concept in producing or sharing the information and how these ethical factors affect their behavior of social media uses. After survey with the structured questionnaire, statistical analyses with available 227 cases are processed. As a result, there are 4 ethical factors in using social media which as included 'privacy', 'copyright', 'fullness', 'accuracy', 'truth-telling', 'fairness', 'relief of harmful effect', 'credibility', 'objectivity', 'impartiality', included 'moderation', 'respect', 'autonomy', 'control', 'care of mischief', included 'interactivity', 'multiplicity', 'anonymity', 'divergence', 'social community', included 'transparency', 'openness'. All these ethical factors are positive correlated to the level of social media users' opinion expression, opinion support, information leading, information searching. Especially, is the most effective factor to social media users' behavior.

In this paper, a motor gearbox fault-detection system based on a hierarchical flow-based model is proposed. The proposed system is used for the anomaly detection of a motion sound-based actuator module. The proposed flow-based model, which is a generative model, learns by directly modeling a data distribution function. As the objective function is the maximum likelihood value of the input data, the training is stable and simple to use for anomaly detection. The operation sound of a car's side-view mirror motor is converted into a Mel-spectrogram image, consisting of a folding signal and an unfolding signal, and used as training data in this experiment. The proposed system is composed of an encoder and a decoder. The data extracted from the layer of the pretrained feature extractor are used as the decoder input data in the encoder. This information is used in the decoder by performing an interlayer cross-scale convolution operation. The experimental results indicate that the context information of various dimensions extracted from the interlayer hierarchical data improves the defect detection accuracy. This paper is notable because it uses acoustic data and a normalizing flow model to detect outliers based on the features of experimental data.

This study focused on consumer information search activity and consumer's post-purchase satisfaction. For these purpose, a survey was conducted suing questionaires on 430 homemakers that lived in seoul. Statistics used for data were Frequency Distribution. Percentile, Mean, One-way AAANOVA., Scheffe-test, T-test, Pearson's correlation. Multiple Regression Analysis and Multiple Classification Analysis. The major findings were ; 1) The level of each amount information search was lower than average. And the level of consumer's post-purchase satisfaction was a little higher than average. 2) On amount of "noncommercial-personal" information search, the influencing variables were desire to seek information, education, brand royalty in turn. These three variables explained 7% of dependent variable's variance. 3) On amount of "noncommercial-media" information search, the influencing variables were desire to seek information, amount of internal information, education, occupational status in turn. These variables explained 14% of dependent variable's variance. 4) On amount of "commercial-personal" information search, the influencing variable was desire to seek information, and this variable explained 3.1% of dependent variable'a variance. 5) On amount of "commercial-media" information search, the influencing variables were desire to seek information, education, amount of internal information in turn. These three variables explained 12.1% dependent variable's variance. 6) Resulting from multiple classification analysis, influencing variables on consumer's post-purchase satisfaction were amount of noncommercial-media information search and printed media search, and brand royalty. These three variables explained 9% of dependent variable's variance. Furthermore, througout all the subareas of consumer's satisfaction, the amount of noncommercial-media information search was the most influencing variable.

현재 국내·외적으로 VoIP 관련 시장의 지속적인 성장으로 인해 VoIP 표준 프로토콜에 대한 국제 표준화 작업과 병행하여 프로토콜 스택과 같은 소프트웨어 개발이 절실한 상황이다. 본 논문에서는 IETF RFC2705에서 제시한 MGCP 문법을 기반으로 문법 지식적 변환 기법으로 Media Gateway가 전달하는 MGCP 요청 메시지를 구조체 형태로 변화하는 엔코더와 Media Gateway Controller로부터 전달되는 구조체 형태의 응답 메시지를 텍스트 형태로 변화하는 디코더를 구현하였다. 이를 위해 BNF 형식의 MGCP 문법을 기술하여 구문 분석 동작 후 구문 트리 및 MGCP 문법으로부터 생성 가능한 모든 정보를 저장할 수 있는 구조체 형태의 헤더 파일을 자동 생성하였다.
