Due to the development of the digital technology, the digital broadcasting is changing to a multi-entertainment platform that can operate data (broadcasting) services (such as games, weather information, and stock trading services) as well as traditional broadcasting contents. Most of the data services, however, failed to get satisfactory results because of the inconvenience in operating the services using a TV remote controller and the failure of gaining the viewer's interests in the competition with the broadcasting contents. The paper introduces a survey on the viewer's modality of using a data service and, based on the survey result, proposes a design guideline that makes a data service minimally interrupt a viewer watching a broadcasting content.

As music streaming services (MSS) involve various interactions with users during the music consumption process, it is important to understand the user experience and manage the service accordingly. This study developed a user experience model for MSS by theoretically linking the quality characteristics considered important by music service users with the structure of user experience. PLS analysis was then performed using survey data to test the model. As a result, functionality (search, browsing, and personalized recommendation), UI usability, content quality (currentness, sufficiency, relevance), and monetary cost were found to be key experience factors that determine the experience consequence, i.e., user satisfaction. In addition, in a supplementary analysis comparing domestic and global services, differences in user experience were found between the two groups in terms of functionality and content quality. The user experience model of MSS proposed in this study serves as a new foundation for theory-based research in this field and provides meaningful implications for the competitive landscape among music streaming service platforms and for their competitive strategies.

The increased needs for medical cost containment and the quality of life improvement for the low-income elderly with chronic disease require the complementary relationship between hospital care and community health services. This study investigated the current status of the linkage between Korean hospital care and community services using Seoul Welfare Panel Study(SWPS) data. Logistic regression analysis was used to examine the effects of experiences of hospitalization and outpatient health services on use and needs of community health services. The analysis results indicated that the elderly with chronic disease who have not experienced outpatient health services were unlikely to receive health and social services in the community. Even those who have experienced hospitalization were not provided complementary health services in the community despite the increasing demand.

This study aimed to elucidate the differences in nursing service experience according to the participants' characteristics and experience of hospitalization and to identify the relation between nursing service experience and perceptions of the health system. It analyzed the data from a "Survey of health care service experience" conducted among 574 participants who had been hospitalized. The results showed that the mean nursing service experience of participants who had never used other hospitals before hospitalization with over ten days of hospital stay was higher compared with the other participants. Moreover, those who used other hospitals before hospitalization reported lower nursing service experience scores. In the classification based on the change of the inpatient room, the difference in the nurse service experience according to the number of hospitalization days was significant only in patients who had no change in the inpatient room in the multi-person room. The nursing service experience scores were positively related to general satisfaction with the hospitalization experience, health system satisfaction, and trust in the health system. This finding implies that the nursing service experience should be interpreted by separating the inpatient experience, and the strategies to improve the nursing service are needed. In addition, the survey should include items related to the characteristics of medical institutions such as nurse staffing, to identify factors affecting the experience of nursing services.

This study aimed to develop Research Data Management (RDM) Services in a domestic university library of Korea. In this study, elements and levels of RDM services are examined and in-depth interview was conducted with university researchers affiliated in Seoul National University, which has the largest amount of research fund among universities in Korea. Interview was conducted to analyze their data management practices and needs of RDM services. Interview results show researchers' lack of awareness toward Data Management Policy and data sharing obligations of funding agencies and academic journal publishers. Also, they had trouble managing research data systematically. However, many of the researchers understand the necessary of research data management and education of data management. Based on the interview result, service elements and contents are suggested for RDM services which is consisted of education services, professional consulting services, curation technical services. This study result will help to guide for the planning the future RDM service in university library of Korea.

Because the movie has the characteristics of a cultural product where experience is important, a promotional strategy is used to convert viewers into movie audiences by providing indirect experiences of movies through professional movie information programs. Considering that the movie information program is a strategic publicity medium that raises the audience's intention to watch a movie, a study on the data service that provides useful additional information to the viewer in conjunction with the movie information program is meaningful. Against this background, this study contains the core research contents in the development of data service linked with movie information program. Specifically, additional information of the movie information program was defined. And to provide the additional information to the data service, the digital broadcasting international standard DVB-SI-based additional information transmission method was devised.

본 논문은 메타버스 환경에서 문제가 대두되고있는 AI 윤리(ethic)를 배경으로 인터랙션을 통해 사람들의 온라인과 오프라인의 결정요소에 직접적으로 영향을 미치는 대화형 AI가 어떻게 윤리적으로 진화될 수 있을지에 대한 공학적 솔루션을 UX 관점으로 찾아보는 기술 전략 연구라고 할 수 있다. 연구의 가설은 AI 의 머신러닝과정에 개별 사용자 그룹의 경험데이터가 반드시 포함되고 고려되어야 AI 는 오류값을 줄이고 윤리적으로 대응할 수 있다는 전제이다. 이를 위하여 본 논문은 기존의 머신러닝과 대화형 AI 의 UX 관점의 다이아로그 플로우 등을 연구 분석하고 사용자 데이터들을 실험하여 메타버스 서비스 환경에서의 기존에 논의되고 있는 컨택스트기반의 AI 머신러닝 과정에 사용자의 정성적 경험데이터를 추가한 윤리적 UX 접근 개념 모델을 제안 하였다. 아직은 개념모델 단계이고 시스템에서는 지금까지 다르지 않았던 비정량적인 감정과 융합적경험을 어떻게 문화적으로 코드화 하고 시스템적인 랭귀지와 연결시킬 수 있을지에 대한사용자 연구가 후속연구로 진행될 예정이다.

최근 사물인터넷에 대한 발전이 빠르게 이루어짐에 따라서 인터넷 상의 보안 이슈 또한 증가하고 있다. 이에 따라 데이터를 안전하고 은밀하게 통신하기 위한 공개키 기반 구조 (public-Key Infrastructure: PKI) 기술이 발전하고 있다. PKI는 신뢰할 수 있는 기관에서 개인이나 기관을 식별할 수 있는 인증서를 저장하고 있으며 이를 활용할 수 있도록 돕는 디렉토리 서비스를 제공한다. 특히 기존의 PKI 구조에는 사용자의 경험이 담겨있는 패스워드 기반으로 개인키를 암호화 하고 있다. 이는 사용자 인증과 데이터 암호화와 같은 강력한 보안 서비스를 제공하고 있지만 이 또한 취약점을 내포하고 있다. 본 논문에서는 공개키 기반 구조의 핵심 요소에 대해 논의하며 보안 취약점을 분석한다. 이를 통해 안전한 사물인터넷 환경을 위한 연구 방향을 제시한다.

Smart Farm, which combines information and communication technologies with agriculture is moving from simple monitoring of the growth environment toward discovering the optimal environment for crop growth and in the form of self-regulating agriculture. To this end, it is important to collect related data, but it is more important for farmers with cultivation know-how to analyze the collected data from various perspectives and derive useful information for regulating the crop growth environment. In this study, we developed a web service that allows farmers who want to obtain necessary information with data related to crop growth to easily analyze data. Web-based data analysis serivice developed uses R language for data analysis and Express web application framework for Node.js. As a result of applying the developed data analysis service together with the growth environment monitoring system in operation, we could perform data analysis what we want just by uploading a CSV file or by entering raw data directly. We confirmed that a service provider could provid various data analysis services easily and could add a new data analysis service by newly adding R script.
