Recently, people can create small content by themselves and it improved into a form that can be promoted. Also, as active small business owners increase, they produce the content for promotion by themselves without external professional help and they utilize it. This paper studies the method to make Mobile Apps, Mobile Web and homepage services available by automatically generating the mobile based mini content. The automated content creation system suggests the method that small business owners and groups can easily communicate with new people by bringing Single Page Application, hybrid mobile web app, N-Screen based content building, private cloud-based PaaS building technology, P2P network based file sharing and multimedia thread technologies together and creating the content.

In the mobile Internet, users generally work with handheld devices with limited computing power and small screens. Their access conditions also change frequently. In this paper, we present a novel method supporting intelligent content adaptation to better suit handheld devices. The underpinning is a unit of information (UOI)-based content adaptation method, which automatically detects semantic relationships among the components of Web contents and then reorganizes page layout to fit handheld devices based on identified UOIs. Experimental results demonstrate that our method enables more sensitive content adaptation.

The moisture content of crude oil notably affects various aspects of oil production, storage, transportation, and exploration. However, accurately measuring this moisture content is challenging because of numerous influencing factors, leading to a lack of precision in existing detection methods. This inadequacy hinders the progress of China's petroleum industry. To overcome these challenges, this paper proposes a conductivity-based method for measuring crude oil moisture content. By employing an embedded system, we designed a sensor comprising five electrodes. Additionally, we developed signal excitation and signal processing circuits. Moreover, a software program was designed to analyze and compute the output signal using fast Fourier transform operations. This facilitated the identification of flow patterns, computation of relevant flow rates, and establishment of correlation rates based on frequency spectral characteristics. Based on experimental results, we established a functional relationship between measurement parameters and crude oil moisture content. This study enhanced the precision of moisture content measurement, thereby addressing existing limitations and fostering the advancement of China's petroleum industry.

The purpose of this paper is to propose a method to maximize the efficiency of a content-based image retrieval for various kinds of images. This paper discuss the self-adaptivity for the change of image domain and the self-selection of optimal features for query image, and present the efficient method to maximize content-based retrieval for various kinds of images. In this method, a content-based retrieval system is adopted to select automatically distinctive feature patterns which have a maximum efficiency of image retrieval in various kinds of images. Experimental results show that the Proposed method is improved 3% than the method using individual features.

The purpose of this study is to design a Content-based Korean Class model using Flipped learning for foreign students. The class model that presents on this paper will lead the language learning through content learning, also it will be enable the student more active and to have an initiative in the class. Prior to designing a Content-based Korean Class model using Flipped learning, the concepts and educational significance and characteristics of flip learning were reviewed through previous studies. Then, It emphasizes the necessity of teaching method adapting Flipped learning to Content-based teaching method in Korean language education. It also suggests standards and principles of composition in Contents-based teaching method using Flipped learning. After designing the instructional model based on the suggested standards and principles, it presents a course of instruction about how learning methods, contents and activities should be done step by step. The Content-based Korean class model using the Flipped learning will be an alternative approach to overcome the limitations of teacher-centered teaching methods and lecture-teaching methods which are the dominant of present classroom environment.

Purpose: This study was to develop Web-based multimedia content for Physical Examination and Health Assesment. Method: The multimedia content was developed based on Jung's teaching and learning structure plan model, using the following 5 processes: 1) Analysis Stage, 2) Planning Stage, 3) Storyboard Framing and Production Stage, 4) Program Operation Stage, and 5) Final Evaluation Stage. Results: The web based multimedia content consisted of an intro movie, main page and sub pages. On the main page, there were 6 menu bars that consisted of Announcement center, Information of professors, Lecture guide, Cyber lecture, Q&A, and Data centers, and a site map which introduced 15 week lectures. In the operation of web based multimedia content, HTML, JavaScript, Flash, and multimedia technology(Audio and Video) were utilized and the content consisted of text content, interactive content, animation, and audio & video. Consultation with the experts in context, computer engineering, and educational technology was utilized in the development of these processes. Conclusions: Web-based multimedia content is expected to offer individualized and tailored learning opportunities to maximize and facilitate the effectiveness of the teaching and learning process. Therefore, multimedia content should be utilized concurrently with the lecture in the Physical Examination and Health Assesment classes as a vital teaching aid to make up for the weakness of the face-to- face teaching-learning method.

협력적 여과 시스템은 ｛사용자-문서｝의 행렬을 기반으로 사용자에게 웹 문서를 추천하는 데 있어서 효율적인 시스템이다. 그러나 협력적 여과 시스템은 초기 평가 문제와 희박성으로 인하여 추천의 정확도가 저하된다는 단점을 갖는다. 본 논문에서는 협력적 여과 시스템의 희박성과 초기 평가 문제를 해결하기 위하여 사용자 프로파일을 생성시킴으로써 자동으로 선호도를 평가하는 방법을 제안한다. 본 논문에서 사용하는 프로파일은 협력적 여과 시스템에서의 ｛사용자-문서｝ 행렬을 기반으로 생성된 사용자 프로파일에 내용 기반 여과 시스템에서 연관 피드백을 이용하여 생성한 사용자 프로파일을 상호정보의 방법에 의해 병합함으로써 생성한 내용 기반 협력적 사용자 프로파일이다. 생성한 내용 기반 협력적 사용자 프로파일을 정규화시키고, 정규화한 프로파일을 협력적 여과 시스템의 ｛사용자-문서｝ 행렬에 반영함으로써 자동으로 선호도를 평가한다. 제안된 방법은 사용자가 웹 문서에 대해서 선호도를 평가한 데이터베이스에서 평가되었으며, 기존의 방법보다 보다 효율적임을 증명한다.

인터넷 망은 대역폭이 일정치 않기 때문에 대용량 콘텐츠의 전송 QoS를 보장하기 어렵다. 현재 QoS를 보장하기 위해 사용되는 보편적인 방법은 콘텐츠 전송 네트워크인 CDN(Content Delivery Network)을 사용하는 방법이다. 본 논문에서는 기존 CDN에 적용할 수 있는 메타데이터를 이용한 콘텐츠 배포 및 관리(CDM: Content Distribution and Management using Metadata) 시스템을 제안한다. CDM 시스템은 전송률을 높이기 위하여 파일 단위로 전송되는 기존 방법 대신 병렬 전송이 가능한 세그먼트 단위 전송 방법을 지원한다. 또한, 사용자가 요구하는 내용의 콘텐츠를 우선 배포하기 위한 내용 기반 검색을 통한 배포방법을 지원한다.

연동형 방송 서비스 구현 시 배경이 되는 오디오/비디오 스트림과 오버레이 되는 데이터 콘텐츠의 시간 동기화는 중요한 문제이다. 그러나 현재 MPEG-4 환경에서는 절대적인 시간 값을 바탕으로 각각의 데이터를 동기화하는 기초적인 방법을 이용하고 있다. 따라서 본 논문에서는 연동형 방송 콘텐츠 개발 시 효율적인 데이터 동기화를 위해 비디오 콘텐츠의 내용에 따라 데이터 콘텐츠의 내용이 변화하는 내용 기반 동기화 기법을 제안한다. 제안하는 내용 기반 동기화 기법은 장면 키워드를 바탕으로 BIFS 노드를 확장 정의하고 MPEG-7의 메타데이터를 이용하여 구현되었다.
