Traditional Business Intelligence environment is limited to support the rapidly changing businesses and the exponential growth of data in both volume and complexity of data. Companies should shift their business intelligence environment into Self-Service Business Intelligence (SSBI) environment in order to make smarter and faster decisions. However, firms seem to face various challenges in implementing and leveraging the effective business intelligence system, and academics do not provide sufficient studies related including the success factors of SSBI. This study analyzes the three cases of Korean companies in depth, their development process and the assessment of business intelligence, based on the theoretical model on the key success factors of business intelligence systems. The comparative analysis of the three cases including project managers' interviews and performance evaluations provide rich implications for the successful adoption and the use of business intelligence systems of firms. The study is expected to provide useful references for firms to fully leverage the effects of business intelligence systems and upgrade towards self-service business intelligence systems.

Smart Mirror is one of the representative technologies developed as a new communication method to escape the traditional technology by applying to the existing space. In this paper, we applied Smart Mirror to the beauty space to discover the service providing value needed to provide the beauty care service and to study the user experience for the value enhancement. In-depth interviews were conducted to investigate the user experience for enhancing the value of service provision. The results of analyzing the collected data using the affinity method were derived. Finally, the service value that can increase the user's satisfaction through the focus group interview was suggested, which suggested a way to improve the user's experience through the smart mirror.

Considering the number of population commuting from Gyeonggi to Seoul, the development of the bus system is relatively slow. There are many problems to be solved but it has been overlooked, leaving the users in discomfort. The goal of this research is to improve the current system to satisfy the unmet needs, using HCI methods, which is composed of five steps, including Define, Find, Analyze & Synthesize, Ideation, Develop. In Define, we recruited the interviewees using the extreme user method to find their needs. In Find, we proceeded 'be the customer', shadowing for background research and in-depth interview. In Analyze & Synthesis, we analyzed the customer needs and clustered to similar needs to draw useful ideas. After that we suggested sophisticated ideas based on design principles from previous stage and visualized in user scenarios and mock-ups. Overall, the research suggests with text message service, informative light service and mobile application to improve the existing bus station.

Why people share location context information? The purpose of our study is that why users share location context information and which factors is related to co-experiences in LBSNS. Through an exploratory approach, first, we conducted a qualitative study in order to understand experiences among people in LBSNS and analyzed according to Grounded Theory. As a result, we found concepts regarding co-experiences cooperatively and competitively in LBSNS. Second, the theoretical model of co-experience was constructed by mediating perceived empathy based on theoretical foundation. In this study, theoretically, we suggested exploratory research model of co-experiences in LBSNS. Practically, designers could adopt concepts in terms of competition and collaboration among users to build co-experience of LBSNS services as its guidelines.

This paper deals with usability issue that is one of the important user interface issues in multimedia environment. The purpose of this study is to define the concept of affordance in multimedia environment, which is adapted from product design fields and to seek development plan of more efficient interface and assurance interaction with interface. As a result, it is useful that the concept of affordance in multimedia design is applied as a 'useful clue for performing task.' Furthermore, it is possible that the concept of affordance is used as one of the improving methods of usability for users in multimedia environment.

블로그는 현재 광범위하게 대중성을 얻고 있는 온라인 커뮤니케이션의 최근 형태이며, 블로그 사용이 빠른 속도로 주류를 형성해 나가고 있다. 초기 HCI 분야에서의 온라인 커뮤니케이션(CMC)에 대한 연구는 사용자가 시스템의 소프트웨어나 하드웨어의 인터페이스를 어떻게 대하는가 하는 점에 초점이 맞춰졌었지만, 최근에는 온라인 커뮤니티, 블로그처럼 사용자들이 인터넷을 통한 사회화가 어느 때보다 활발하게 이루어지고 있기 때문에, 시스템의 사용성에 대한 고려만으로는 충분하지가 않다. 즉, 시스템이 어떻게 사용자들 간에 사회적 상호 교류를 지원할 수 있고, 이러한 사회적 교류가 원활하게 이루어지기 위해서 시스템이 어떻게 설계되어야 하는 지에 대한 이해가 필요하다. 따라서 본 연구에서는 실제 블로그 이용자들을 대상으로 이들과 상호 연결된 블로거들과의 온라인에서의 관계적 행위를 살펴보고, 또한 이러한 행위가 네트워크 구조적 특성과는 어떠한 상관 관계를 가지는지를 심층 인터뷰와 사회 네트워크 분석법을 이용하여 탐색적으로 알아보고자 한다. 본 연구 결과를 통해서 얻은 사용자들의 온라인 교류 시 보이는 행위적 특성을 바탕으로 온라인 개인 미디어 서비스 설계에 대한 가이드라인을 제안해 보고자 한다.

Education will be undergoing major changes with the 4th industrial revolution. As education contents will be important in future smart home service, in-depth interviews were conducted against experts and analyzed by the grounded theory approach. Eleven categories emerged through the analysis. In order for educational content to be utilized in smart home services, value creation (central phenomenon) seems to be most critical with preceding overcome of hamlet syndrome. Diversity of content and connectivity (context) should be ensured, and studies that could enhance user experience (intermediary situations) should be conducted and reflected in the content curation and realtime response (interaction strategy). As a result, it can be inferred that the education content service can be expanded in smart home services while satisfying self-development desire of individuals through these processes. Additional selective coding revealed four immediate need area: self-development, home-improvement, health care, and mindful healing.

게임의 교육적 목적으로의 활용에 대해 관심이 늘고 있다. 이러한 흐름 속에서 최근 게임을 통한 리더십 함양이 화두가 되고 있다. 각 기업체에서는 직원들의 리더십 함양을 위해 게임을 활용하고자 다양한 시도를 꾀하고 있기도 하다. 특히 이 같은 흐름에는 무엇보다 MMORPG 게임이 두드러진다. 왜냐하면 MMORPG 에는 현실 세계와 흡사한 정치, 경제, 사회 시스템이 내재되어 다수의 플레이어와 협동, 경쟁을 하며 목표를 달성해나가는 과정이 담겨있기 때문이다. 하지만 현실과 많은 유사성을 가지고 있는 가상세계이지만 현실과 동일한 잣대로 가상세계에서의 사용자의 성향을 판단하기에는 아직 무리가 있다. 분명 게임이라는 가상공간과 현실세계는 명백한 차이점이 존재하기 때문이다. 그럼에도 불구하고 게임 내에서의 리더십 유형과 현실에서의 리더십 유형간의 직접적인 상관관계에 대한 연구가 아직 이루어지지 않았다는 점에 초점을 맞추었다. 다시 말해 게임을 통한 현실에서의 리더십 함양의 가능성을 언급하기에 앞서 근본적으로 현실과 가상공간에서의 리더십 양상의 상관성에 대한 연구가 선행되어야 한다고 생각된다. 본 연구는 우선 현실세계에서의 리더십 성향이 가상세계에서도 동일하게 적용되는지 1군주의 사용자를 중심으로 살펴본다. 그리고 군주 사용자의 심층인터뷰를 통하여 게임 내에서 리더십을 발현시킬 수 있는 여러 요소 (긍정적 요소 장애요소 등)를 살펴보고 향후 리더십 함양을 위한 게임 기획에 도움이 되고자 한다.
