In this study, in order to provide an app with improved usability to users in the trend of gradually increasing the number of users of music streaming services, usability tests were conducted by conducting interviews before and after the execution of the screen test technique and the performance measurement method and contextual. Usability test was conducted using the Inquiry method. Usability tests were conducted by one user each from their teens to their 50s, and were conducted on Melon, YouTube Music, Genie, and FLO apps with many service users. As a result of the usability test, the icon does not sufficiently represent the function and is not recognized as an interactive button, which is overlooked by the user, the problem that the user does not recognize due to lack of visual effect when the function is activated, The problem was derived. In this regard, suggestions for improving the user screen, such as intuitively changing the icon for each app, adding a visual effect of the screen when the function is activated, and adjusting the position so that the function has continuity, were presented along with the visual data.

This study conducted voluntary focus group user observations to empirically validate the efficacy of the self-developed psychological support mobile application, "Mindful Now". The app is structured as an interactive game format, enabling individuals to activate self-awareness of mindfulness states anytime, anywhere. It consists of a 3-step process of sensory/emotional/consciousness awareness, facilitating the expression of non-judgmental awareness. To demonstrate the effectiveness of this mindful activation in enhancing psychological well-being such as happiness and stress reduction, voluntary mindfulness mobile app usage was tracked among 49 university students. The results revealed significant improvements, with a 14.4% increase in SWLS happiness index and a 17.1% decrease in PSS-10 stress levels among 12 users who used the app continuously for over 60 days to practice mindfulness awareness. Particularly, higher app engagement was observed among students who initially reported relatively lower indices before using the app. The utilization of mobile apps that promote mindful activation aligns with various therapeutic paradigms based on mindfulness and meditation, contributing to advancements in digital therapeutic interventions for psychological support.

Various applications are widely developed for smartphones to meet customer's needs. In many companies, messenger's typed interactive systems have been studied for business marketing, advertising and promotion to provide useful services for the customers. Such interactive systems are usually called as "Chatbot". In Chatbot, duplicated responses from Chatbot could occur frequently, and these make one lose interest. In this paper, we define a case that the response of Chatbot is duplicated according to the user's input, and propose a method to reduce duplicated responses of Chatbot. In the proposed method, we try to reduce duplication responses through a new duplication avoidance algorithm by building multiple tables in a database and by making combinations of user's input and its response in each table. In our experiments, the proposed method shows that duplicated responses are reduced by an average of 70%, compared with the existing method.

본 과제는 지구본에 비행기를 융합한 놀이 및 학습 도구이다. 기존의 지구본은 낮은 연령대의 아이들에게 교육적 효과를 줄 수 있으며, 유아에게 호기심 유발이 적고 국한된 정보를 제공한다는 문제점을 가지고 있었다. 본 과제에서는 유아에게 더 많은 호기심 자극과 정보를 제공할 수 있게 상호작용적 기능이 내장된 스마트 지구본을 제안한다. 본 연구의 결과는 유아 및 아동들에게 교육적 효과를 줄 수 있고, 스마트폰 어플리케이션 연동으로 인한 간단한 거리뷰 및 지도를 나타냄으로써 다양한 목적을 가지고 활용할 수 있을 것으로 기대된다.

In the 21^st century, the growing use of information and communication technologies (ICTs) and social media platforms has influenced our way of life, including international diplomacy. With the use of new interactive communication technologies such as WhatsApp, Twitter, Facebook, Instagram, video sharing website, blogs, and other social media networks, digital diplomacy has become an active diplomatic mode in modern society and plays an increasing important role in international relations. Although Indonesia has gradually realized the pivotal role of internet diplomacy and recently put it into practice, it is still lagging far behind. This paper will examine how Indonesia conducts its diplomacy in the new era of digital world. How far and in what ways does the Indonesian government make use of digital technology to conduct its diplomacy? What opportunities and challenges are confronted to develop digital diplomacy? How does it navigate diplomacy in the digital age? Unless Indonesia embraces new channels and methods of diplomacy, its foreign policy implementation may not run optimally to support its aim of attaining its objectives in the international stage.

The purpose of this study was to evaluate the usability of a hybrid mobile reading game among 14 parents of children with reading disabilities. The reading game consisted of six steps according to the process of reading (familiarizing with consonants and vowels, acquiring whole words, combining consonants and vowels, reading words, phonological rules, reading fluency). In this study, parents experienced steps one through three of the reading-game app and evaluated the general design features and Universal Design for Learning on a five-point scale. Regarding the general design features, parents rated usability (18 items in total) as high in the following order: interactive design, instructional design, and interface design. Regarding the Universal Design for Learning (9 items in total), parents evaluated usability as high in the following order: providing multiple means of representation, providing multiple means of action and expression, and providing multiple means of engagement. Lastly, suggestions for the improvement of the app, practical implications, and suggestions for future research are discussed.

As community revitalization among local residents is currently emphasized, village regeneration projects and village culture activation projects are being promoted in various ways based on the participation of residents. Community mapping is one of the projects in which the residents of the community propose and improve the problems of the community as subjects. This community mapping draws residents's interest in the village through the process in which residents directly map the major issues in the village and makes it possible to draw the voluntary participation of the residents in deciding village plans and policies. In this study, we used community mapping to develop a safety map application for interactive communication of local residents. The developed app enables local residents to directly upload and share information on local issues and problems. In addition, the purpose is to find ways to share and improve safety related issues and problems of the village with relevant administrative agencies using the developed app.
