The design of a museum mobile application's user experience demands an in-depth comprehension of the user experience dimensions and the unique attributes of the user experience elements that users may encounter. This paper through a series of experimental studies and analyses of experiences related to the use of museum mobile applications, derives a user experience framework consisting of four dimensions and 19 elements, which has been verified for feasibility. The study shows that all four dimensions have a positive impact on user satisfaction, but the degree of impact varies. Among them, emotionality of use and ease of use have the greatest impact, while usefulness of use and multiformity of function have relatively less impact. In addition, the user experience of museum mobile application can also positively influence the user's future intention to recommend, continue using, and even the actual visit to the museum.

The emergence of open source software(OSS) with its most prominent advantages creates a vast interest among practitioners. A study on Linux, the most well-known OSS, estimated that it would cost as 5.4 billion Euros taking over 73,000 person-years if it had been developed by conventional means. However, Linux has achieved only 0.65 percent of the operating system market for individual users while Microsoft windows family counts for nearly 90 percent of the market. Much of the effort being spent in the development of OSS is going to waste and potential value that OSS can bring to users is not being realized. Adoption of OSS is often accompanied by the discontinuance of existing software that is already in place. If users resist changing, they may not adopt OSS. Using the case of Linux, this study examines user resistance to change from the commercial operating software to the free operating system. This study identifies six sub-types of switching costs (uncertainty, emotional, setup, learning, lost benefit, and sunk costs) and tests their effects on user resistance to change based on a survey of 201 users. The results show that user resistance to change has a negative impact on the adoption of OSS. Further, this study shows that uncertainty and emotional costs have significant effects on user resistance to change. Beyond previous research on technology adoption, this research contributes towards an understanding of the switching costs leading to user resistance to change and offers suggestions to OSS practitioners for developing strategies to improve the adoption of OSS.

Given the proliferation of social network services, it has become important to understand its user's continued use behavior. As users' privacy concerns in SNS have been identified as a critical barrier against forming this continued intention, many studies have focused on inducing continued intention by mitigating privacy concerns. However, this paper suggests to approach users' continued intention not only from the perspective of mitigating privacy concerns but also from the perspective of increasing potential benefits. Under the theoretical framework of privacy calculus model, we conducted cross sectional survey on 150 Facebook and 150 KakaoTalk users. The result suggests that trust mediates the relationships between privacy concerns and continued intention and between network externality and continued intention, and the influence of support for network formation on continued intention. The effect of network externality on continued intention, however, is not significant among Facebook users while it is significant among KakaoTalk users.

Due to the recent changes in residential value, user needs for various spaces in residential space are increasing. However, it is not easy to change and reconstruct the first residential form according to the needs of the user due to the characteristics of the residential space where movement and deformation are difficult. Therefore, this study aims to derive a plan to meet user needs according to changing residential value by using fully autonomous vehicles with a concept of space that can be moved. First, the existing residential space was classified through literature research, and based on this, the space type of the fully autonomous vehicle for the residential was derived through user research. Then, through the survey method and statistical analysis, user needs analysis for residential space, usefulness analysis of derived space type and type specification were carried out. Finally, based on the results of the study, the design direction of the fully autonomous vehicle for residential purpose was presented. Based on the user's perception, it is meaningful that it categorizes the space of the fully autonomous vehicle for residential purposes and suggests the design direction.

SNS uses the Internet as its base. It is created in order to achieve communication between the users. Up until now, most previous research were focused on the users of SNS. But, there are still a great deal of people who do not use or discontinuously use SNS. This is because users have natural resistance against SNS when using the service. In this study, time shortage perception, awareness of SNS, self-efficacy, suitability, information quality of SNS, subjective norm and privacy concern are considered as influence factors by previous research. An empirical study for Chinese students and internet users was conducted to identify how these factors influence perceived risk and perceived usefulness, and how this influence to user's resistance. This study can explain the reason why users don't use SNS and resist SNS use.

최근 들어 신세대들은 온라인을 통해서 아바타를 활용하여 가상공간 속에서 자신을 표현하고 있는 추세이다. 아바타는 ‘분신’, ‘화신’을 의미하는 산스크리트어로 가상공간에서 사용자의 역할을 대신하는 애니메이션 캐릭터이다. 가상공간 속에서 오프라인 상에서 표현하지 못한 자신만의 캐릭터를 통해서 자신의 정체성을 시각적으로 표현하여 개인의 개성을 표출하고 있다. 이러한 아바타의 출현으로 인터넷에서의 자기표현 방식이 외향적인 형태로 변화하는데 이는 새로운 표현에 대한 사용자의 수용도에 따라서 여러 가지 형태로 나타나고 있다. 특히, 사용자가 새로운 개념을 수용하는데 있어서 그들이 잠재적으로 보유하고 있는 특성에 따라서 아바타의 표현이 다각적으로 연출되고 활용되어지고 있다. 이는 신세대들의 자기표현 방식이 다양하기 때문이다고 할 수 있겠다. 신세대들은 또한 새로운 정보통신 기술이 매체를 통해 보급될 경우 수용도가 다른 세대에 비해 빠르다. 이렇듯 아바타의 도입과 활용은 신세대의 자기표현의 상징적인 역할을 하고 있다. 현재, 웹과 핸드폰을 통해서 2D 기반의 아바타가 활용되고 있으며, 신기술이 지속적으로 개발되고 있다. 현재 개발되어지고 있는 3D 핸드폰 아바타의 수용도에 대한 관심도도 높아질 것으로 예상된다. 현재 아바타 개발과 활용에 대한 연구는 활발히 진행되고 있지만, 이러한 신세대들의 특성에 따른 아바타의 수용에 대한 연구는 아직 정립되지 못하고 있다. 아바타의 수용에 관한 이론은 심리적 특성 이론으로 자아 존중감, 유행 선도력, 소비가치 등이 있으며, 사용자 수용 이론으로 혁신 성향, 유흥 성향 등이 있다. 이를 기반으로, 본 연구에서는 신세대 대학생들의 특성에 따라서 아바타의 수용도에 미치는 영향을 모색하고자 한다. 이를 위해서 대학생들의 특성을 심리적 특성이론과 사용자 수용이론으로 구분하여 이 특성에 따라서 향후 개발될 3D 핸드폰 아바타의 수용도의 관계를 파악하고자 한다. 본 연구에 대한 자료 수집방법은 D대학교의 교양과목인 “사이버문화의 이해와 활용”을 수강하는 학생들을 대상으로 총 170부를 설문 조사하였으며, 수집된 설문지 중에서 불성실하게 응답한 설문지 6부를 제외한 총 164부를 유효한 설문으로 확보하였다. SPSSWIN 10.0 패키지를 이용하였으며, Cronbach's Alpha값을 통한 신뢰도 분석과 요인분석을 통한 타당성 분석을 하고, 연구변수로 선정한 각 요소들의 아바타 수용도에 미치는 영향력 정도를 파악하기 위해 회귀분석을 실시하였다. 그 결과 심리적 특성과 사용자 수용 특성은 아바타 수용도에 부분적으로 영향을 미친다는 것 결과가 나타났다.

With the development of digital technology related to mobile, cloud, IoT, even traditional businesses have began to develop strategies for digital transformation. This is regarded as a very important part for business sustainability. However, many of these attempts are being conducted from the management point of view, and there has been little research on user experience design for digital transformation. In this study, Starbucks, which started a offline store business and expanded its experience with online services, was selected as a representative case and user research was conducted on it. Through an usability evaluation and post-task interviews of the Starbucks mobile application users, we discovered important issues of user experience to consider when transforming and expanding services online from offline. Based on the findings, the considersations for designing online user experience were discussed and proposed. These are expected to contribute to the process of researching and implementing digital transformation.

The survey was conducted on the Bungae Jangter and Danggeun Market, which provide mobile used market services. The goal is to investigate factors that affect the user experience of used market platforms and to compare usability. Based on Peter Morville's Honeycomb Model, a survey and In-depth interviews were conducted to users with experience in secondhand transactions. And we qualitatively analyze the factors that affect the user experience. As a result, there were differences in usability depending on the age of the user. (reliability, how to find things, purpose of using used trading services, etc.) This study focused on actual user experience, so it will help you find a way to develop to user-centered secondhand marketplace services.
