웹 기반 코스웨어들이 많이 개발되고 있다. 그러나, 기존에 개발된 대부분 웹 기반 코스웨어들은 학습자들에게 항상 같은 교수 방법을 제공하므로 학습자들의 다양한 요구를 수용하는데 부족한 면이 있다. 학습자들이 개별적으로 가장 적합한 교수 방법으로 학습한다면 학습 효율을 높일 수 있을 것이다. 본 연구에서는 학습자의 개인차를 고려하면서 다양한 학습 방법을 제공하고, 교수 시스템은 교수 방법 중에서도 학습자에게 효율성이 높다고 생각되는 교수 방법을 학습자에게 추천하도록 하고, 학습자는 선호하는 방법을 선택하여 학습하도록 하였다. 평가모듈은 개개인의 응답에 대하여 개별적인 피드백을 주었다. 그리고 이 프로토타입 시스템을 대학1학년을 대상으로 적용하여 본 시스템의 교육적 효과를 입증하였다.

Currently, it is not easy for most domestic public libraries to collect and provide reliable health information services on their own. Health information is distributed or professional, making it inconvenient for users to use. Based on the implications derived from the case study, the Library Health Information Integration Service Model was proposed as a specialized information service. The model consists of a composition shared by librarians, health and medical experts, and users, focusing on library websites that provide integrated health information integration services, and has the following features. First, it provides health and medical information on a specialized subject. Second, it provides integrated health and medical information services provided in various ways. Third, librarians and health and medical experts work together to provide information services. Fourth, users can freely use health information integration services online and offline. The model presented in this study means that libraries can play a leading role in health information integration services to increase the utilization rate of public libraries and further contribute to librarians serving as experts in health information services.

Purpose: To compare and analyze current state of domestic and foreign educational program to develop a program and provide basic information for qualitative improvement of the program. Method: Referred to records and used various methods as searching on the Internet. Analyzing methods and standards are as follow : 1) As for the current status of domestic educational program, find out about organizations that conduct the program 2) As for the current status of foreign program, find out about United States, Canada and United Kingdom. 3) As for comparison and analysis, find out about curriculum, subject, the number of people, content, cost and time. Results: In comparison and analysis of subjects and program, United States, Canada and U. K. specified the subjects according to occupations to offer various programs appropriate for special occupational situations whereas domestic program only provide education of CPR and usage of AED. Foreign countries provide sufficient time from 5.5 to 40 hours according to occupations. In contrast, Korea only provide 2-4 hours of educations, which is insufficient to master techniques of first aid. In addition, foreign countries precisely regulate organizations that fulfill the qualification and specific guidelines for content of education. However, Korea doesn't have any standards of qualification or guidelines. Discussion: It is necessary to specify first aid education according to occupations to provide diverse programs. Furthermore, it is necessary to establish nationwide regulations for subjects and content of the programs of the first responder.

In this paper, we present a method to customize the ground color in outdoor sports video to provide TV viewers with a better viewing experience or subjective satisfaction. This issue, related to content personalization, is becoming critical with the advent of mobile TV and interactive TV. In outdoor sports video, such as soccer video, it is sometimes observed that the ground color is not satisfactory to viewers. In this work, the proposed algorithm is focused on customizing the ground color to deliver a better viewing experience for viewers. The algorithm comprises three modules: ground detection, shot classification, and ground color customization. We customize the ground color by considering the difference between ground colors from both input video and the target ground patch. Experimental results show that the proposed scheme offers useful tools to provide a more comfortable viewing experience and that it is amenable to real-time performance, even in a software-based implementation.

The existing mashup service providers have induced users to participate in their own made services and have grown their services by user participations and contributing contents. Recent services based on Web2.0 are called by 'Open (Content) Service' which means anyone can provide new services to the others without any of their own contents. But unfortunately the most of these days services are not opened. They just using mashups for increasing their service's traffics. We introduce the way to make a simple service to provide searching videos present it with extracted keyword from external content without our own contents at all. this show that how to combine the content with another contents or services.

In this paper, we proposed a mechanism that prevents indiscreet use of digital contents, verifies created content's copyrights to provide services to granted user and protects digital contents by law by authenticating the original digital content whenever an infringement of copyright occurs in UCC environments. The proposed mechanism uses specific information and features of contents as copyrights authentication information without additional information. Also, provides the fact of violation by inferring the modification of the original digital contents. That means this mechanism infers same or similar value from the contents; fraudulent use of content, modification of content color, modification of content format, modification of content resolution and illegal use of frame not principal key frame. In that point, we found that the inferred value from the content differed according to features of content modification.

It is difficult for mobile learners to maintain a high level of concentration when learning content for more than an hour while they are on the move. Despite the attention span issue, many m-learning systems still provide their mobile learners with the same content once used in e-learning systems. This has called for an investigation to identify the suitable characteristics of the m-learning environment. With this in mind, we have conducted a survey in hopes of determining the requirements for developing more suitable m-learning content. Based on the results of the survey, we have developed a content model comprised of two types: a segment type and a supplement type. In addition, we have implemented a prototype system of the content model for Apple iPhones and Android smartphones in order to investigate a feasibility study of the model application.

Purpose: Monitoring and control of environmental condition is highly important for optimum control of the conditions, especially in greenhouses and plant factories, and the condition is not uniform within the facility. Objectives of the study were to investigate variability in soil water content and to provide information useful for better irrigation control. Methods: Experiments were conducted in a strawberry-growing greenhouse (greenhouse 1) and a cherry tomato-growing greenhouse (greenhouse 2) in winter. Soil water content, electrical conductivity (EC), and temperature were measured over the entire area, at different distances from an irrigation pump, and on ridge and furrow areas. Results: When measured over the entire greenhouse area, soil water content decreased and temperature and electrical conductivity increased over time from morning to afternoon after irrigation. Water content decreased by distance from the irrigation pump up to 70 m and increased after that, and temperature showed an inverse pattern. Soil water contents on the ridge were lower than those on the furrow, and the differences were 10.2~18.4%, indicating considerable variability. The lowest EC were observed on the furrow and highest values were observed on the ridge. Soil water contents were less and temperature levels were greater at the window side than in the center locations. Conclusions: Selection of number and location of soil water content sensor would be the first step for better water content monitoring and irrigation control. Results of the study would provide basic data useful for optimum sensor location and control for underground greenhouse environment.
