The popularization of mobile Internet applications has accelerated the development of smart tourism industry. Based on TAM and VAM theories, this paper studies the influencing factors of tourism App users' willingness to continue using through complex network and data analysis methods. Through the research, it is found that the improvement of service level and design concept of smart tourism application can accelerate the aggregation of complex networks and improve user engagement. At the same time, reasonable price service experience value, convenience service experience value, interactive service experience value, emotional design perception, ease of use design perception, entertainment design perception and other factors can have a direct impact on users' intention to continue to use, and there is a significant correlation. The smart tourism App's convenience and price advantage are the root of its competitiveness. The design concept can affect users' emotional experience and perceptual experience, and help smart tourism App improve users' satisfaction.

In this paper, we design thin-client framework capable of application sharing & data access on the Internet, and apply related skills, such as X windows system, pseudo server, CODA file system, MPI(Message Passing Interface). We suggest a framework for the thin client to access data produced by working on a server optimally as well as to run server side application, even in the case of network down. Additionally, it needed to reflect all local computing changes to remote server when network is restored. To design thin client framework with these characteristics, in this paper, we apply distributed pseudo server and CODA file system to our framework, also utilize MPI for the purpose of more efficient computing & management. It allows for implementation of network independent computing environment of thin client, also provide scalable application service to numerous user through the elimination of bottleneck on caused by server overload. In this paper, we discuss the implementing method of thin client framework in detail.

In this paper, we present a mobile application for 'personalized customized learning' for children with articulation disorders using an artificial intelligence (AI) algorithm. A dataset (Data Set) to analyze, judge, and predict the learner's articulation situation and degree. In particular, we designed a prototype model by looking at how AI can be improved and advanced compared to existing applications from the UX/UI (GUI) aspect. So far, the focus has been on visual experience, but now it is an important time to process data and provide a UX/UI (GUI) experience to users. The UX/UI (GUI) of the proposed mobile application was to be provided according to the learner's articulation level and situation by using CRNN (Convolution Recurrent Neural Network) of DeepLearning and Auto Encoder GPT-3 (Generative Pretrained Transformer). The use of artificial intelligence algorithms will provide a learning environment with a high degree of perfection to children with articulation disorders, thereby enhancing the learning effect. I hope that you do not have any fear or discomfort in conversation by improving the perfection of articulation with 'personalized and customized learning'.

Software birthmark refers to a unique feature inherent in software that can be extracted from program binaries even in the absence of the original source code of the program. Like human genetic information, the similarity between programs can be calculated numerically, so it can be used to determine whether software is stolen or copied. In this paper, we propose a new birthmark technique for Android applications developed using Unity. The source codes of Unity-based Android applications use C# language, and since the core logic of the program is included in the DLL module, it must be approached in a different way from normal Android applications. In this paper, a Unity birthmark extraction and comparison system was implemented, and reliability and resilience were evaluated. The use of the Unity birthmark technique proposed in this paper is expected to be effective in preventing illegal copy or code theft of the Unity-based Android applications.

This study reviews the literature on the utilization of gamification elements in digital applications for cognitive assessment and rehabilitation of the elderly, focusing on both domestic and international research from 2015 to 2024. Following the PRISMA methodology, inclusion and exclusion criteria were applied to align with the research objectives. Out of 1,718 initial studies, 18 were ultimately analyzed after a screening and filtering process. The results of this literature review indicate a growing interest in cognitive training and other interventions aimed at mitigating cognitive decline among the elderly. Additionally, it was found that the gamification elements of digital applications are effective in engaging elderly users and improving cognitive functions such as memory, attention, and executive function. The findings of this study suggest that integrating gamification elements can enhance user engagement and provide practical solutions for cognitive health management. Further research is needed to explore the long-term effects and broader applicability of these digital interventions.

우리나라 전력계통 네트워크는 SCADA를 통해 데이터를 취득하고 있다. 초창기 SCADA를 도입할 당시에는 이 시스템이 성능과 기능면에서 그 당시의 최신기술이며 유일한 네트워크 모델이었다. 특히 핵심적인 부분에서는 국내 순수 기술이 아닌 외국 제품이 적용되었다. 그러나 근래에 기술동향은 정보통신의 점진석인 발달과 하드웨어의 성능 향상 등을 통해 동일조건에서 동인 시스템을 구축할 경우 이전과 비교해 볼 때 월등한 효율성과 경제성을 갖출 수 있다. 특히나 전력계통의 경우 신뢰성을 기반으로 한 국가 기간산업이므로 이러한 기술을 적용한 파급효과는 보수적인 면이 있다. 따라서 본 논문에서는 이런 특성을 고려하여 현재의 SCADA를 분석해보고 애플리케이션을 추가할 경우에 어떻게 설계해야 할지에 대해 살펴보고자 한다.
