This study aimed to have an understanding of how the users of comprehensive care service for the aged experience the user-centered services. For this, this study placed focus on the essential aspects of the experience of using the service including the meaning of the choice of users being emphasized as practical principles in user-centered services as well as the real context of such a choice. The research methods suggested by Giorgi in phenomenological studies were adopted for data analysis, and intensive interviews were conducted for 10 users living in Seoul who are over 65 years of age. According to the results of the analysis, the interviewees' experience of the service as users were categorized into the elements of "restricted choice of service", "unstrengthened right for the users", "ambivalent emotion about the service", and "awareness of the importance of the relationship with the caregiver", and the essential phenomenon in their experience of the service was "the importance of relationship within restricted choice". This study found out that the choice or self-determination of users was still restricted in the usage of user-centered services. It also found out that the users think it more important to have a positive relationship with the caregiver than the choice of the service granted to them. On the basis of such research results, political implications are proposed to help the establishment of user-centered services.

This study describes behavioral characteristics of Korean population over twenty years old in a variety of activities of daily living by analyzing the raw data of the time use survey provided by Statistics Korea (KOSTAT). Seven activities and forty four sub-activities of daily living were selected for analysis : personal care, employment, household care, family care, voluntary work and community participation, social life, recreation and leisure, and travel. In order to quantitatively understand how Korean adults spend their time for a day and how their lifestyle changes over time, we collected the time recorded by 3,673 respondents in three surveys over the past ten years (in 1999, 2004, and 2009). Then, we performed analysis of variance to compare the behavioral characteristics by user age and gender based on the mean time of each activity. The differences in behavior among user groups and over time could be used to design ergonomic products and services based on user experience, especially for universal design of housing and transportation facilities.

The purpose of this study was to propose a "user experience (UX)-centered product development process" so that the product design development process using the service design process can be systematized and used in practice. In a situation in which usability research on office phones is lacking compared to general home phones, this study expands to a product-based service design point of view rather than simple product development, intending to research ways to provide user experience value through office phone design in smart office. This study focused on extracting UX-centered user needs using the service design process and developing product design that realizes user experience value. In particular, the service design process was applied to systematically extract user needs and experience value elements in the product development process and to discover ideas that were converged with product-based services. For this purpose, the "Double Diamond Design Process Model," which is widely used in the service design field, was adopted. In addition, a product design development process was established so that usability improvement plans, user experience value elements, and product-service connected ideas could be extracted through a work-flow in which real users and people from various fields participate. Based on the double diamond design process, in the "Discover" information collection stage, design trends were identified mainly in the office phone markets. In the "Define" analysis and extraction stage, user needs were analyzed through user observation, interview, and usability survey, and design requirements and user experience issues were extracted. Persona was set through user type analysis, and user scenarios were presented. In the "Develop" development stage, ideation workshops and concept renderings were conducted to embody the design, and people from various fields within the company participated to set the design direction reflecting design preference and usability improvement plans. In the "Deliver" improvement/prototype development/evaluation stage, a working mock-up of a design prototype was produced and design and usability evaluation were conducted through consultation with external design experts. It is meaningful that it established a "UX-centered product development process" model that converged with the existing product design development process and service design process. Ultimately, service design-based product design development process was presented so that I Corp.'s products could realize user experience value through service convergence.

Basically, modern architect's translation of relations between architectural space and human beings is focused upon the space and the way the space is experienced. Thus, the architecture is construed not as the finalized and fixed structure but as something undetermined and In progress. Here, we can identify the similarity between current trend and theory on process. Experience argument in this study is based upon such a similarity. And for your understanding of the spatial concept broached in the following experience argument, I've presented the analysis of Ben van Berkel's and Kazuyo Sejima's works that represent user's experiences in discussing art works. Taking a step further, I'll try to provide the true definition of being in progress and the potential of the architecture, thereby seeking the value and meaning of trends in modern architecture. In this regard, this study is aimed to analyze the attributes of experiences in progress identified in the art works of Ben van Berkel and Kazuyo Sejima and to extract and analyze the architectural concepts therein.

This study aims to examine the characteristics of the user experience of New Town neighborhood parks and explore issues that diversify the experience of the parks. In order to quantitatively analyze a large amount of park visitors' experiences, text-based Naver blog reviews were collected and analyzed. Among the Phase 1 and 2 New Towns, the parks with the highest user experience postings were selected for each city as the target of analysis. Blog text data was collected from May 20, 2003, to May 31, 2022, and analysis was conducted targeting Ilsan Lake Park, Bundang Yuldong Park, Gwanggyo Lake Park, and Dongtan Lake Park. The findings revealed that all four parks were used for everyday relaxation and recreation. Second, the analysis underscores park's diverse user groups. Third, the programs for parks nearby were also related to park usage. Fourth, the words within the top 20 rankings represented distinctive park elements or content/programs specific to each park. Lastly, the results of the network analysis delineated four overarching types of park users and the networks of four park user types appeared differently depending on the park. This study provides two implications. First, in addition to the naturalistic characteristics, the differentiation of each park's unique facilities and programs greatly improves public awareness and enriches the individual park experience. Second, if analysis of the context surrounding the park based on spatial information is performed in addition to text analysis, the accuracy of interpretation of text data analysis results could be improved. The results of this study can be used in the planning and designing of parks and greenspaces in the Phase 3 New Towns currently in progress.

An estimated 1 billion mobile phone were sold globally in the year 2006. In Korea, people watch television 3.17 hours in a day. Television isn't what it used to be. Digital TV provides both interactivity and high definition. Mobile phone also transferred from 2G to 3G or 3.5G. This means the complexity of TV and mobile phone is increased, design of user interface is more difficult. Unlike the personal computer industry, TV and mobile phone industries have no standard user interface. A comparative study for user interface between TV and mobile phone is studied. User, task, system are analyzed in requirement analysis. User interface model and interaction are also analyzed between TV and mobile phone. This study provides some insights for user interface design. First, the UI designer have to consider another products because one user using one product at the same time using another products. Experience for one product affects that for another product. Second, TV and mobile phone show very similar pattern, especially interaction task and input interaction. Third, there are not sometimes optimized experience between service operator and device manufacturer. Cooperative design between them is required.

Purpose This paper attempts to explain the recent expanding trend in Mobile Grocery Shopping(MGS). More specifically, the authors have applied the Post Acceptance Model(PAM) in order to examine the conceptual structure among the four constructs of 'Expectation Confirmation', 'Perceived Usefulness', 'User Satisfaction', and 'Continuance Intention to Use' in Mobile Grocery Shopping. Design/methodology/approach Through a survey agency, data were collected from a sample of 312 consumers who had the previous experience in Mobile Grocery Shopping. The Structural Equation Modeling(SEM) analysis was conducted with the survey data using AMOS 22.0. Subsequently, 8,200 real customer data from an open market site were collected in order to find out their revisit and repurchase behavior. Findings This study supported the causal relationships of Expectation Confirmation → Perceived Usefulness, Expectation Confirmation → User Satisfaction, Perceived Usefulness → User Satisfaction, and User Satisfaction → Continuance Intention to Use, but did not support the direct effect of Perceived Usefulness on the Continuance Intention to Use Mobile Grocery Shopping. This implies that consumers with any experience in Mobile Grocery Shopping would not consider repurchase, unless they are satisfied with the experience even though they perceive its usefulness. Also, Expectation Confirmation has much larger effect on User Satisfaction than Perceived Usefulness. In addition, the real customer data showed that the revisit and the repurchase rate of mobile grocery shoppers were higher than those of online grocery shoppers, although the rates of adding to shopping carts, coupon downloads, and adding to favorites are similar.

Sanitary pads are used with for the sanitization of menstruation bleeding. In this research, twenty medium size disposable sanitary pads were selected from domestic and international brands in order to analyze their shape and size. Additionally, 6 sanitary pads were selected among the 20, and user experience evaluations were completed. The analysis on the shape of the 20 sanitary pads showed that straight-shape pads existed more than curved-shape pads. The means of total pad length, wing length, wing width, front pad width, back pad width, front pad length, and back pad length were 24.5 cm, 8.8 cm, 3.0 cm, 10.0 cm, 10.2 cm, 11.6 cm, and 13.0 cm, respectively. All selected pads were medium size; however, detailed sizes varied between brands. Eighty-one women participated on user experience evaluation. Participants felt that brand F was the longest and brand D the shortest. The results matched with the results on actual pad length measurement. Participants evaluated the fit of brand E most positively and fit of brand A most negatively. The current study provides valuable information for developing disposable sanitary pads.
