Interactive media is a method of communication in which the output from the media comes from the input of the users. The interactive media lets the user go back with the media. Interactive media works with the user's participation. The media still has the same purpose but the user's input adds the interaction and brings interesting features to the system for a better enjoyment. We need a digital content using a dynamic motion and gesture of the mobile device. We made an authoring tool for content producers to easily create interactive content. We have tried to take advantage of the interaction by using a touch screen and a gravity sensor of the mobile device. This interaction may lead to allow the user to participate in the content, it can be used as a key device to assist in engagement. Furthermore, our authoring tool can be applied to various fields of publishing content.

디지털 콘텐츠 시장의 성장은 다양한 콘텐츠 소비 장치의 개발을 유도하였고, 디지털 콘텐츠의 소비를 더욱 촉진시켰다. 그러나 디지털 콘텐츠의 안전한 소비를 위해서는 단말에서 의 디지털 콘텐츠 보호를 위한 암호화 툴의 관리가 필요하다. 또한 각 단말의 특성에 적합한 유동적인 암호화 툴 전송 프로토콜이 표준화되지 않아 단말에서의 암호화 툴 관리 상호운용성 부재가 발생한다. 이에 본 논문에서는 디지털 방송 콘텐츠 보호와 소비를 위해 암호화 툴의 전송 프로토콜을 정의하였으며, 이를 기반으로 보호관리 툴 서버와 보호관리 툴 클라이언트를 설계 및 구현하였다.

In order to provide continuous Korea Augmentation Satellite System (KASS) services, the operation organization should continuously and systematically perform operations, maintenance, and technical activities. All subsystems of KASS, all Line Replacement Units (LRUs), and Software Replacement Units (SWRUs) should be operated and maintained continuously. In order to effectively manage these activities, it is necessary to develop an Operation Management Tool (OMT). For this purpose, operation management, operation organization, and operation activities were defined. The defined requirements were divided into general, function, interface, and database for OMT development, and functions and decision-making procedures consisting of site/asset/trouble/work order/schedule management were designed. The OMT developed by reflecting the site and asset information as well as the design content met predefined requirements. The OMT will be actively used in actual KASS operation and will evolve by continuously reflecting the additional requirements of operators. Through this tool, KASS will support continuous service provision.

기존의 LMS(Learning Management System)는 학습자의 의도와 무관하게 처음부터 끝까지 모든 교육 내용을 모두 학습하게 구성됨으로써 온라인 교육의 목표인 언제 어디서든 이라는 원칙이 구현되지 못하고 있다. 또한 학습자가 요구하는 내용으로 수정 및 보완이 용이하지 않고, 개발 시간이 느리고 비용이 많이 소요된다. 따라서 학습자 요구에 맞는 교육컨텐트를 개발하려면 LCMS(Learning Content Management System)기반으로 교육코스를 개발하는 저작도구가 필수적이다. 본 논문에서는 학습자 요구에 맞는 교육과정을 개발하고, 교육의 효율성을 극대화 시키는 방법으로 학습객체 단위로 CDT-L(Course Development Tool-Learning Content Management System)을 개발하고자 한다. 또한 다른 객체와의 관계등을 생성함으로써 학습자에게 꼭 필요한 정보를 찾을 수 있도록 해주어 이를 통해 학습자 중심의 학습을 가능케 한다. 학습자의 특성을 고려한 맞춤식 교육 코스 구성으로 앞으로는 자신이 원하는 과정을 선택하고 학습자에게 맞는 코스 강의로 강의가 이뤄지는 것을 가능하게 하기 위해 코스와 학습객체에 대한 메타데이터를 표준 문서인 SCORM 1.2에 기반하여 정의한다. 정보를 가지고 있는 학습객체를 선택하여 파일과 정보를 저장한 식별하기 위하여 검색을 한다. COT-L의 구현을 통해 컨텐트 재활용도를 높이면서 교육과정의 개발시간과 비용을 줄일 수 있다.

Purpose: The purposes of this study were to develop a nursing assessment tool for senior center nurses, and to test its feasibility and content validity. Methods: The study utilized a psychometric test design. Preliminary items were developed based on geriatric health needs and Gordon's 11 domains of functioning health. Initially, the tool was evaluated for content validity and feasibility. Then, it was administered among 195 older adults in a senior center by a gerontological nurse practitioner. Data were analyzed to describe the nursing problems of the senior center older adults. Results: The final version of the nursing assessment tool consisted of 27 items. The internal consistency, measured with the Cronbach's ${\alpha}$, was .74. The result of the assessment showed that senior center older adults had high nursing needs in the area of management of chronic diseases (hypertension, diabetes, and lipids), dental care, community relations, safety, elder abuse, health behaviors (such as drinking), mental health (depression, suicide, and cognitive function), and health consultations. Conclusion: The new tool was feasible for use with senior center participants, and it was evaluated as having high content validity by senior center nurses.

As users' needs for customized services increase, the service provision method is changing from a vertical structural service provision method to a horizontal structural service provision method. This paradigm shift has led to a change from the way existing users find the content they want to find and provide customized needs of users by content providers. With the recent development of smartphones and various AI technologies, demand for providing seamless services such as smartphones is increasing in automobiles. However, it is difficult to provide services in line with changes in this service paradigm because automobile services provide services centered on finished car manufacturers rather than individually providing services tailored to user needs. In this paper, we develop a Node-RED-based dynamic vehicle service simulation tool so that users can use the service they want in cars. The simulation tool developed provides a simulation environment for services authored by the user using NodeRed by writing, registering, and using NodeRed.

Background: Regional Cardiocerebrovascular Centers (RCC) were established for the prevention and treatment of cardiocerebrovascular disease and funded by the Ministry of Health and Welfare. The purpose of this study was to develop and validate the measurement tool of public benefits in RCC. Methods: Through the intensive literature review, experts surveys and their repetitive feedback, we selected the 46 items about the public benefits in RCC. Development of measurement tool involved content validity test using Content Validity Index (CVI), construct validity test through factor analysis and reliability test. Results: Thirty-five items were selected by content validity test, which CVI was 0.08 or higher. Through the construct validity test, 32 items in 7 factors were derived. And Cronbach's alpha was 0.951. Finally, public benefits measurement tool is composed of 32 items in 7 factors which are comprehensiveness of health care services, market complement, emergency care, cost, governance, quality improvement, and government control. Conclusion: Though we developed the measurement tool of public benefits in RCC, it would be utilized to measure the public benefits of various health agencies.

The purposes of this study were: a) to develop the a quality measurement tool for the contract-managed hospital foodservice, and b) to evaluate their performance with the developed quality measurement tool, and c) to verify the reliability and validity of the quality measurement tool. The developed quality measurement tool comprised two parts, which were foodservice management and medical nutrition care service. The foodservice management part was classified into six functional categories which were Menu, Procurement and Storage, Production and Distribution, Facility and Utility, Sanitation and Safety, and Management and Evaluation. The medical nutrition care service part indicated the medical nutrition care provided. Quality measurement tool had 91 standards and 324 indicators. The quality measurement tools were distributed to the hospital foodservice manager employed by the foodservice company. The 324 indicators were measured by foodservice manager on the 5-Likert-type scales, and then adapted to a 100 point scale. The SPSS Ver. 11.0 was used for statistical analysis. The categories whose scores were evaluated as being high were Procurement', General Sanitation', Personal sanitation' and Waste' and the categories whose scores were evaluated as being low were Diet Order Manual', Standard Recipe', Appropriateness (Facility and Utility)', Check (Facility and Utility)'and Information Management'. All the categories of medical nutrition service were evaluated as having seriously low scores. Therefore, it was necessary for the contract-managed hospital foodservice to improve its performance in the area of medical nutrition care service. For the verification of the developed quality measurement tool, the reliability obtained by calculating Cronbach's α was 0.8747, and the content validity was also proved by scrutiny of the modification of the Professional group's techniques.

디지털 콘텐츠 시장의 성장은 다양한 콘텐츠 소비 장치의 개발을 유도하였고, 이는 디지털 콘텐츠의 소비를 더욱 촉진시켰다. AXMEDIS(Automating Production of Cross Media Content for Multichannel Distribution)는 다양한 플랫폼에서의 디지털 콘텐츠 소비를 지원하기 위해 AXMEDIS 프레임워크를 통한 다양한 디지털 방송 솔루션을 제공하고 있다. AXMEDIS 프레임워크는 단말에서의 디지털 콘텐츠 보호 및 소비를 위해 암호화 툴을 사용한다. 그러나 단말간의 유동적인 암호화 툴의 전송이 불가능하여 단말에서의 암호화 툴 관리가 불가능하다. 이에 본 논문에서는 AMEDIS 프레임워크에서 디지털 방송 콘텐츠의 보호와 소비를 유동적으로 운용 가능하도록 AXMEDIS 암호화 툴 전송 모듈을 설계 및 구현하였다.
