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.

Sensors equipped in Internet-of-Thing (IoT) devices are used to measure the surrounding contexts, and IoT applications analyze the contexts to infer situations and provide situation-specific smart services. There are different context acquisition schemes including pulling, pushing, and broadcasting. Most IoT devices support only one of the schemes. Hence, there can be an incompatible issue on data acquisition schemes between applications and devices, and consequently it could result in an increased development cost and inefficiency on application maintenance. This paper presents design patterns which can effectively remedy the incompatibility problem. By applying the patterns, IoT applications with incompatibility can be systematically and effectively developed. And, also its maintainability is expected to increase.

The purpose of this study is to empirically verify how UI usability of mobile healthcare applications affects the perception of technostress and continuous use of elderly users. Through this, the effect of UI usability of mobile healthcare applications on technostress and continuous use intention was demonstrated for 199 people aged over 60. As a result, all four sub-factors of UI usability had a significant effect on technostress, and the magnitude of the influence was found to be in the order of content, process, design, and system. On the other hand, it was found that technostress had a significant effect on the intention of continued use. Through the above results, a UI design strategy that can lead to continuous use by relieving the technostress experienced by the elderly was suggested. This provides academic and practical implications for the future development and service direction of mobile healthcare applications for the elderly.

Air pollution due to the fine dust level updating every day, and the problem of indoor air pollution due to ventilation difficulties and indoor discharge pollutants is also serious. In order to improve the indoor air quality, the air purification effect using the plants is prominent. In this study was started to investigated the living environment of modern people, the risk of indoor air pollution and the improvement function of plants, and to activate plant application. The purpose of this study is to analyze the main functions and design status of domestic and overseas plant - related applications, and to understand the actual use of modern plant applications and to help them learn more convenient plant - related knowledge. Therefore, this paper attempted to establish a basis for suggesting a new plant application by conducting a survey on the health effects of indoor air pollution and user awareness of plant - related applications. The results and contents of the study are as follows. First, as a theoretical review, indoor air pollution is more dangerous to modern people who have a high proportion of indoor living time and adversely affects their health. In order to solve such a problem, it has been shown that air conditioning and stress reduction can be effectively achieved by placing plants in the indoor space. Second, the analysis of the previous study shows the risk of indoor air pollution and its adverse effects on health. In addition, I have been able to find some researches related to the improvement of the indoor air by using the air purifying plants, and I can see the improvement of the user's behavior through the development or improvement of the application. Third, as a result of the survey on the status of domestic and overseas plant application, the main function of the application having high installation number was watering notification, provision of basic information of plants, and most of the functions were plant discerment through cameras. Fourth, most of the survey respondents have either raised or raised plants. Those who have little experience with plant applications have also shown positive feedback in the future on the use of plant-related applications. In addition, due to social problems such as air pollution, air purification using plants and functional plants showed high interest. Based on these results, we propose the need for a multi-functional plant application that can improve the indoor air pollution and facilitate the provision of information related to it.

In the Big Data era, data science has become popular with the production of numerous data in various domains, and the power of data has become a competitive power. There is a growing interest in unstructured data, which accounts for more than 80% of the world's data. Along with the everyday use of social media, most of the unstructured data is in the form of text data and plays an important role in various areas such as marketing, finance, and distribution. However, text mining using social media is difficult to access and difficult to use compared to data mining using numerical data. Thus, this study aims to develop Korean Natural Language Application (KoALA) as an integrated application for easy and handy social media text mining without relying on programming language or high-level hardware or solution. KoALA is a specialized application for social media text mining. It is an integrated application that can analyze both Korean and English. KoALA handles the entire process from data collection to preprocessing, analysis and visualization. This paper describes the process of designing, implementing, and applying KoALA applications using the design science methodology. Lastly, we will discuss practical use of KoALA through a block-chain business case. Through this paper, we hope to popularize social media text mining and utilize it for practical and academic use in various domains.

On the contrary to the steady rise of social problems about depression, only a few take care of mental health themselves due to their negative perception of psychotherapy. In this study, we propose service design and user interface design of mobile applications that introduce an automatic emotional recognition system to prevent leaving depression unattended. First, we have come up with improvements in the usability of existing apps through literature research and case analysis, and draw out Personas from surveys and in-depth interviews of young people. As an essential element of the design of the Depression Improvement Service, we recommend having three components: writing a diary to manage schedule, recognize users' emotional state through avatar management, and tracking down emotional points to improve the cognitive system. Through this proposal, we want to prevent the development of depression and help to resolve the changes in perception of depression and longitude depression on our own. Ultimately, we publicize the necessity of mental health care application design and expect to lower the personal and social costs for psychiatric care.

The market penetration of the smart phones has brought significant changes to the related industries. As the mobile phone market as well as the smart phone application market are growing rapidly, competition among small-size application developers has become severe. However, due to the severe competition and expensive market entry costs, the developers argue that it is necessary to develope the applications from the perspective of the users. However, studies on application development from the users' perspectives are still in the early stages and they have not provided various approaches. Therefore, based on the Open Coding method of Ground Theory, this study collected data on applications review from related communities and blogs of Korean web portal sites, and identified indices which users consider important when they use the applications. In addition, we conduct a comparative analysis between those indices by calculating their frequency of exposure. As a result, a total of 30 sub-categories of indicators such as amusement, controllability, versatility and ease of use appeared to be predominant to users and those lower categories were grouped into five categories; sensibility, design, technology, price, and social skills. The results of this study suggest to the application developers the guidelines of user oriented design and development. It can be used to develop the evaluation tool for application usability.
