현재 사회적인 이슈가 되고 있는 불량 식품에 대한 경각심을 아이들에게 심어주어 좋은 식습관을 유지하도록 교육하는 앱을 개발하고자 한다. 개발하고자 하는 앱은 몸에 안좋은 불량식품을 좋아하는 아이들에게 경각심을 일깨워 주며, 불량 식품에 첨가된 발암불질, 표백제 등이 성장기 아이들에게 치명적임을 인식시키는 정보제공을 하며, 게임 형식을 통해 스스로 좋은 것과 나쁜 것에 대해 확인하여 창의적 자아활동을 유도 한다. 음식에 대한 올바른 이해와 함께 성장기 어린이들의 인지 및 언어 능력을 학습하고자 개발하였다.

Mobile devices are generally using app images which are artificially designed. Accordingly, this paper presents adjusting device brightness based on app image categorization for enhancing the visibility under various light condition. First, the proposed method performed two prior subjective tests under various lighting conditions for selecting features of app images concerning visibility and for selecting satisfactory range of device brightness for each app image. Then, the relationship between selected features of app image and satisfactory range of device brightness is analyzed. Next, app images are categorized by using two features of average brightness of app image and distribution ratio of advanced colors that are related to satisfaction range of device brightness. Then, optimal device brightness for each category is selected by having the maximum frequency of satisfaction device brightness. Experimental results show that the categorized app images with optimal device brightness have high satisfaction ratio under various light conditions.

Worldwide Electric Vehicle (EV) sales are rapidly increasing. But in many cases, charging locations can be found within or near downtown area of the city which makes EV users living outskirts of the city very difficult to establish their daily EV charging routines. In order to improve this situation, we have come up with a daily EV charge service connected with convenience stores and restaurants within reach of most EV users living in South Korea. We aim to allow users to charge their EVs while they shop and eat, just as if they charge their smartphones at cafes and restaurants. We have gone through user diary research and focus group interview research to figure out current user's concerns regarding charging and maintenance of EVs and applied the findings to our proposed service design.

The study, based on existing studies, explored influencing relationship, suggesting app service quality and user reviews as previous elements to affect use satisfaction about users' comments based on big data and reuse intention. The study includes a comparative analysis of existing studies. Based on such analysis results, the authors looked into app service quality elements perceived by gourmet restaurant app users and the role of user reviews, and suggested practical implications that can help the development and operation of gourmet restaurant app contents. The study subjects were male and female consumers who over 20 years old throughout Korea who had not a searched smartphone gourmet restaurant app in the three months preceding the survey. The subjects were selected from consumers who search the restaurantsby using restaurant apps like Mango plate, Dining code, Hot place, and selecting restaurants. Among them, consumers with experience using restaurants were finally selected for the survey. According to the results, reliability, informativity, and system capability, among service quality, had positive influences on app use satisfaction, while design and mobility had no effect. App use satisfaction had positive influences on app reuse intention. User comment informativity played a controlling role. The study explored the importance of app service quality and user review informativity as elements that affect continued use of gourmet restaurant apps by dining-out consumers.

인터넷의 급속한 발달에 따라 다양한 앱(App)들이 기능적인 디자인으로 변모하고 있다. 그러나 아직 미적인 감성을 기반으로 한 간결성과 단순성에 대한 사용자 입장에서는 많은 불편함이 많은 실정이다. 그래서 이를 극복하기 위하여 앱을 설계할 때 사용자의 만족도도 높이면서 앱의 간결성에 영향을 미치는 요인에 대한 요소를 분석하고자 한다.

Design of the past focusing on molding and system is gradually changed into design focusing on users that reflects design philosophy considering users, and especially, the importance of User Experience Design that is to offer the best experience in using some products or services is realized. This study accessed design based on data having a low effect on function of wearable among changes that UX Design should consider in IoT generation. I think the data is diverse and many existing social commerce app, similar to the layout of the data in IoT devices based on the layout of the interface.Apps that data based model to analyze the layout. and the structure of the UX design were summarized.

The objective of this study is to identify the relationships among app attribution(perceived usefulness, design, information quality, and mobility), user satisfaction, trust, and continuous use intention of bus information apps; The structural equation of AMOS 21.0 was used to test the hypothesis of this study. The results of the analysis are as follows. First, perceived usefulness, design, information quality, and mobility positively impact user satisfaction. Second, only mobility has a positive effect on trust, but the remaining perceived usefulness, design, and information quality have no effect at the significance level of 5%. Third, user satisfaction has a positive impact on trust and continuous use intention. Fourth, trust has a positive impact on continuous use intention. Therefore, it was confirmed that the characteristics of the bus information mobile app are important influencing factors for the improvement of user satisfaction, trust, and continuous use intention. Local governments and bus companies will be able to establish strategic directions for the activation of bus information mobile apps. The limitation of this study is that it is somewhat lacking in generalizing the study results, so future research needs to focus on improving this part.
