With the recent increase in the use of artificial intelligence, AI TRiSM data management within organizations has become important, and thus securing data reliability has emerged as an essential requirement for data-based decision-making. Digital content is transmitted through the unreliable Internet to the cloud where the digital content storage is located, then used in various applications. When detecting anomaly of data, it is difficult to provide a function to check content modification due to its damage in digital content systems. In this paper, we design a technique to guarantee the reliability of video data by expanding the function of data annotation. The designed annotation technique constitutes a prototype based on gRPC to handle a request and a response in a webUI that generates classification label and Merkle tree of given video data.

As the distribution rate of a smart phone which can actualize even augmented reality is getting higher, the application scope of a smart phone is sharply increasing. However, in spite of various functions of it, there is still lack of learning app. Mobile equipments can bring no spatial-temporal restriction of learning to a learner, but they can tempt a learner into inappropriate spaces. In this sense, learning app is necessarily needed to motivate and keep learner's inner desire. This thesis suggested considerations when learning mobile app is designed by analyzing motivation strategy of ARCS Theory and UI of web based contents. Also, a design method of mobile learning app was suggested based on a procedural model of mobile learning app adapting ARCS Theory.

In this paper, we study smart healthcare devices that enable active health care by building health care system with acquaintances or family members rather than single health care. The company develops health care services for families regardless of age and gender through intuitive UI design as a target for young users who serve elderly parents. Automated collection of health information and real-time feedback are available, and data can be aggregated and analyzed through repeaters. It can also utilize structured databases in the form of big data. The services offered can be used to prevent diseases and reduce medical expenses through health care, while automatic management can maximize users' convenience and increase demand. By reducing the development period of products that are based on this technology, reducing the development period of products and strengthening competitiveness, the company has the advantage of inducing generation-to-generation communication in an era when it is becoming a nuclear family.

디지털 카메라의 사용이 일반화되면서, 사용자가 사진을 찍고 보관하고 감상하는 행태가 과거의 일반 카메라와 다른 모습을 보이고 있다. 특히 디지털 카메라는 유지비가 거의 들지 않기 때문에 한번에 촬영하는 사진의 양이 많은 반면에 인쇄하여 보관하는 사진의 양은 매우 적은 경향을 보인다. 디지털 사진의 양이 방대하게 늘어나고, 인쇄하기 보다는 저장 장치에 보관하게 됨에 따라서 과거의 앨범에 인쇄된 사진을 보관하고 감상하던 방식과 감상하는 행태도 변화되었다. 디지털 카메라로 찍어서 하드디스크에 저장한 사진들은 각 폴더에 어떤 사진들이 들어 있는지를 기억하기 어렵기 때문에 앨범을 보는 것처럼 자주 감상하지 않게 되는 경향이 관찰되었고, 또 인쇄된 사진을 보고, 그 사진과 연관된 다른 사진들을 보고자 디지털로 저장되어 있는 하드디스크에 접속하는 경향이 관찰되었다. 본 연구에서는 촬영된 디지털 카메라의 사진을 분류하여 보관하고 감상하는 사용자의 행태를 분석하고, 이에 적합한 새로운 디지털 사진 관리 시스템을 제안하고자 한다. 특히, 자연스럽게 앨범을 넘겨보다가 인쇄된 디지털 사진과 관련된 컨텍스트를 갖는 다른 디지털 사진들을 저장 매체에서 바로 찾아서 디스플레이를 통해 감상할 수 있는 새로운 방식의 UI를 제안하였다. 이를 위해 인쇄된 사진에 사진의 컨텍스트 코드를 함께 인쇄하고, 추후에 출력된 사진의 컨텍스트 코드를 해독하여 원본 디지털 사진 및, 동일한 컨텍스트를 가지는 디지털 사진들을 자동으로 찾아서 디스플레이 하는 검색 및 감상 방식을 사용하였다. 이를 통해 디지털 사진을 감상하기 위해 거쳐야 했던 기존의 번거로운 과정을 단축하고 디지털 사진을 분류하여 보관하고 원하는 사진을 방대한 데이터 속에서 찾아야 하는 문제를 줄일 수 있었다.

Recently, In line with the recent trend of the fourth industrial revolution, many companies and institutions have been increasingly applying automated technologies using artificial intelligence to various tasks. Particularly, due to the government's 52-hour workweek system, companies are increasingly struggling with manpower management. Therefore, they are interested in RPA (Robotic Process Automation) for office environment automation for efficient manpower management. It is being introduced in the back-office business in credit card companies, bank, insurance. These RPA solutions require AI-based recognition technology, scripting technology, business software API-related technologies, and various solutions such as Automate One, Automation Anywhere, UiPath, and Blue Prism are provided. This paper analyzes and describes the technology of RPA solution, the market trend, and the efficiency of RPA adoption.

As the growth of the live streaming service market is accelerating due to COVID-19, the number of downloads and reviews of live streaming mobile applications is also rapidly skyrocketing. This study is to research game streaming applications using Twitch reviews as database. A total of 8 topics are extracted through LDA topic modeling and 7 out of them are detected to be inconvenience factors. Then, to pinpoint the main inconvenience factors, co-occurrence analysis is used in order to find out main factors. Finally, based on previous studies, several solutions are provided, which can solve the inconvenience factors(advertisement, UI design, technology problems) as well as strengthening digital competitiveness. This study will serve as an opportunity to improve digital competitiveness not only for Twitch but also for other game live streaming service companies in the future.

In December 2014, Livestock and Livestock Products Traceability Act was established, allowing consumers to receive livestock traceability information. While the Livestock Traceability System provides consumers with transparent and fair information about their food, it has brought increased workload and penalty burdens to stakeholders in the livestock industry. In this paper, we propose an IoT system for inventory management based on traceability numbers to enable sellers to conveniently provide livestock traceability information to consumers. We analyzed the protocol for managing data from electronic scales and conducted functional testing and verification on mobile devices. Furthermore, we implemented the design and system functionality, taking into account UI/UX on Android OS-based devices to synchronize and interconnect traceability and product information with electronic scales. We anticipate that the proposed approach will minimize user inconvenience and raise production efficiency in the existing market.

For the optimal achievement of system goals through a systematic analysis of the complex problems, systems engineering provides us the concepts and methodology that include comprehensive interpretability (or understandability), universal applicability, and feasibility. Under this aspect, the main objective of this study is that it introduces mathematical system theory (MST) as the fundamental tool of SE into the Inventory Control among the related parts with IE, and review it's applicability. Through its work, we can find that it has the alternative aspects with which it can replace other existing methods for problem-solving in understanding and analyzing structurally systems in themselves as well as being considerable of the time evolutionary process of a given system.

The main factors of determining the Control Line of the Control Chart can be classified as follows: 1) sample size (n), 2) the factor that determines the spread of Control Limits (B), (3) sampling frequency (h). The determination of these factors can be explained according to the extent that occurrences of assignable cause should be detected. The purpose of this paper are two: one is for composing a model of which use should be designated for economic decision on the size of these factors leading to the Control Line of the Control Chart, the other is about what influence increasing or decreasing condition, according to changeability of the size of these factors, of expect cost can have on the economy when the Control Chart is used.
