The background of this study is the trend in which the genres of mobile games are becoming diverse based on advanced smart devices. However, since cut-scenes are still being regarded as somewhat unnecessary elements in digital games, this study seeks to suggest the functions and range of uses of cut-scenes. The scope of this study is to make classifications for the range of uses of cut-scenes in commercialized mobile games according to the genre, and investigate the characteristics of visual expression to create a frame for communicative styles of mobile games. The result of study was that different styles were identified regarding the use of cut-scenes in mobile games just as in existing digital games, however diverse attempts are not yet being made as in early digital games. Future study needs to be carried out on communication styles that match the characteristics of mobile game platforms, in which a module that can be applied in the introduction of a new platform is required.

We need measures that can come up with alternative about fishery living zone and enhance local acceptance for responding to the increase in the proportion of renewable energy production and construction of 12GW Offshore wind power according to Korea's Renewable Energy 3020 initiative and Korean-version New Deal. In this study, We suggest that differentiation plans of co-location model in connection with offshore wind power generation suitable for the East Sea. The East Sea is an optimal site for building of a floating offshore wind power generation(FOWPG) field. It is expected that economic effects like energy production, aquatic resource development and tourism industrialization by farming bluefin tuna which is high valued fish and suitable for offshore aquaculture on public waters in FOWPG field. And we can confirm that budget reduction, smart management by sharing operation management technology and increase in fishermen income.

Today, due to the increase in global population growth, the international community is discussing solving the food problem. The aquaculture industry is emerging as an alternative to solving the food problem. For the innovative growth of the aquaculture industry, smart fish farms that combine the fourth industrial technology are recently being distributed, and full-cycle digitalization is being promoted. Water quality sensors, which are important in the aquaculture industry, are electrochemical portable sensors that check water quality individually and intermittently, making it impossible to analyze and manage water quality in real time. Recently, optically-based monitoring sensors have been developed and applied, but the reliability of monitoring data cannot be guaranteed because the state information of the water quality sensor is unknown. Therefore, this paper proposes an algorithm representing self-diagnosis status such as Failure, Out of Specification, Maintenance Required, and Check Function based on monitoring data collected by water quality sensors to ensure data reliability.

Ascites is a condition in which body fluids are abnormally accumulated in the fish's abdominal cavity, and is an important indicator of the health of flounder. Ascites can occur in the process of infection with bacteria, viruses, parasites, etc., which causes abdominal distension, sluggish growth, and weight loss. In this paper, we tried to find the correlation with other symptoms or diseases that affect ascites symptoms in flounder. As experimental data, ascites symptoms were divided into three states: no ascites, ascites transparent, and ascites opaque, and disease diagnosis data of cultured flounder collected for 7 years were used. After performing an appropriate preprocessing process for the random forest machine learning method, other symptoms and disease factors related to ascites were extracted, and it was confirmed that the proposed model could present the main factors related to ascites.

This paper proposes PredFeed Net, a neural network model that mimics the food distribution of fish farming experts. Unlike existing food distribution automation systems, PredFeed Net predicts food distribution by learning the food distribution patterns of experts. This has the advantage of being able to learn using only existing environmental data and food distribution records from food distribution experts, without the need to experiment by changing food distribution variables according to the environment in an actual aquarium. After completing training, PredFeed Net predicts the next food ration based on the current environment or fish condition. Prediction of feed ration is a necessary element for automating feed ration, and feed ration automation contributes to the development of modern fish farming such as smart aquaculture and aquaponics systems.

본 논문에서는 ERP 시스템의 사용자 정보와 입력 정보를 스마트 폰을 통해 E-paper 디스플레이에 출력하는 디지털 도어사인 시스템을 제안하고, 프로토타입 구현 결과를 보인다. 제안한 시스템은 도어사인 표준양식 이미지의 특정 좌표에 ERP로부터 추출한 사용자 정보를 병합한 중간게시물을 생성하고, 스마트 폰을 통해 입력한 정보를 중간게시물에 추가하여 최종게시물을 생성한다. 생성된 최종게시물 이미지는 BLE 통신 방식으로 E-paper 기반의 디지털 도어사인으로 송신되어 출력된다. 제안한 시스템은 ERP 시스템과 연동되어 연구실, 사무실 등의 점유자의 기본 정보가 자동으로 입력되기 때문에, 사용자는 공지사항 등의 간단한 내용만을 입력하여 도어사인을 갱신할 수 있다. 제안한 시스템의 프로토타입은 전기영동방식의 4.3인치 E-paper 디스플레이를 이용하여 구현하였다.

In the regular evaluation of engineering education accreditation, there should be almost no deficiencies in the program educational objectives, but they are occurring frequently. From the regular evaluation in 2021, the second deficiency is judged as conditional certification. This paper presents an example of the application of the program education goal adequacy review system considering changes in the social environment with a relatively low understanding of educational goal setting while preparing for the engineering education certification system and certification evaluation. In addition, application cases are presented focusing on the certification criteria, engineering education certification judgment guide, and self-study report form for the linkage application between detailed certification criteria in revising and improving educational goals.

Today, many companies are using CRM as a means to secure sales opportunities, improve sales pipelines, and increase customer satisfaction. CRM like this improves the quality of corporate management by understanding customer behavior patterns and utilizes the process of change in the organization's work procedures and technology for marketing, sales, and customer service. In this study, we designed and implemented a small CRM using IP PBX to enable small and medium-sized businesses to introduce CRM without economic burden and measured its performance. As a result, we found a small customer management system (SOHO CRM) has proven its performance.

To prevent the spread of disease in aquaculture, it is a need for a system to predict fish diseases while monitoring the water quality environment and the status of growing fish in real time. The existing research in predicting fish disease were image processing techniques. Recently, there have been more studies on disease prediction methods through deep learning techniques. This paper introduces the research results on how to predict diseases of Paralichthys Olivaceus with deep learning technology in aquaculture. The method enhances the performance of disease detection rates by including data augmentation and pre-processing in camera images collected from aquaculture. In this method, it is expected that early detection of disease fish will prevent fishery disasters such as mass closure of fish in aquaculture and reduce the damage of the spread of diseases to local aquaculture to prevent the decline in sales.

Technological advancements in the field of information and communication have led to the advent and usage of various types of smart devices, which have significantly altered people's usage behaviors and environments. This change has also been applied to the learning environment, where various smart devices are appearing and the learning behavior of learners is changing accordingly. In this study, we investigate learners' perceptions of digital note-taking behaviors focusing on the recently emerged learning media, tablet PCs and digital pens. Drawing upon the expectancy-confirmation model, we conduct a study on the factors affecting the (dis)confirmation and (dis)satisfaction of undergraduate students with tablet PCs and digital pens by comparing their expectations with their actual use experiences. An open-ended survey was conducted among students at C University in Korea, and the responses were analyzed through qualitative content analysis to derive four factors of expectation-confirmation and satisfaction and three factors of expectation-disconfirmation and dissatisfaction. Based on these findings, we provide academic and educational implications.
