This study aims to figure out how the brand experience design elements works in the Shortform video-based branding through case analysis. The sense, feel, think, act, relate experience of Shortform video brand are provided through the implementation of specific experience design elements in the process of the creators expressing personality through social media channels and communicating and interacting with consumers. As a result, LIZIQI's food videos provided a brand identity as an 'Eastern gourmet' to consumers through the audiovisual stimulation of food in video, the cognitive reinforcement which is combined of identities and products, and the behavioral participation by web sites·electronic media. In addition, a strong brand relationship was established by sharing emotional ties using human factors and responsibility through co-branding. This can be extended to various Shortform video contents-based branding cases, and it will suggest a useful approach to the brand building strategy through strategic brand experience design elements.

In this paper, we present a new model of web-based reading education system. The existing web-based reading education system was effective to reinforce interactions of the learners and elevate their reading interests, but the usability of web-based system was extremely unsatisfied during the process of reading required for a long time because it placed importance on the guidance as a result of reading. This paper has divided reading education activities depending upon the times: before reading, during reading and after reading, etc. Web-based reading strategies, which can be actively used at each stage, have been developed to do interaction actively among teachers, students and their parents. Furthermore, application methods of the strategies have been presented depending upon teaching-learning type of Korean language subject, such as professional's cooperative learning and problem solving learning, etc to revitalize reading guidance of regular Korean language class time.

Strategies have to be employed in information systems security in order to build and operate systems for information systems security in effective and structured manner. It is also essential for the entire organization to participate for successful implementation of the strategies and making them work. Current researches on information systems security strategy in organizations, however, have mainly been focused on deployment and operation of countermeasures based on strategic thinking and decision. In consequence, it is lack of research on overall frame for containing consideration factors required for moving and leading the whole enterprise for the holistic security purpose. Therefore, this paper proposes a framework for use in establishment of organization-wide information systems security strategies based on the concept of grand strategy from the traditional strategy research and on the four dimensional features of it.

This study analyzed the moderating role of the suitability factors of corporate strategies and information system strategies targeting small and medium sized transportation companies in Korea. The analytical result has found that the suitable factors of corporate strategies and information system strategies play the moderating role in the ERP introduction factors and internal performance. In other words, the suitability factors of corporate strategies and information system strategies were analyzed to play the moderating role in support of CEOs, education/training, users' IT capabilities, standardization/formulation of business, infrastructure of information technologies, and internal performance. The result of this study based on the above analytical results has found that introduction performance will be maximized when ERP packages are introduced in the small and medium-sized transportation companies and corporate strategies properly harmonize with the introduction strategies of ERP packages in the companies.

The strategic management process includes the establishment of competitive strategy, its implementation and the measurement of its performance. The sucess of strategic management largely depends on the integration of strategic management process into a managerial tool. This study is on the integration of strategic management process into a managerial tool based on the power process, so that it contributes to strategic success or sustainable competitive advantage of a ￡inn In order to do this, I discussed the principles of the power process, its characteristics, and then suggest their applications to the integration of the strategic management process. According to the results, the power process offers a theoretical and managerial tool which integrates the establishment of competitive strategy with managerial concepts, so that it increases the likelihood of strategic success. Furthermore I discussed the position of the power process approach to competitive advantage in a manner that displays similarities and differences with existing approaches such as industry organizational, resource-based and game theory approach.

The purpose of this study is to investigate the effects of scheme based strategy Instruction on problem solving of word problems of ratio and proportion for students with under achievement or at risk for learning disabilities. Three $7^{th}$ graders of underachieving or at risk LD were participated in this study. Three steps of instructional experiment-testing baseline, intervention with schematic-based strategy, testing for the abilities of problem solving, generalization, & sustainability. The results showed that the schema-based strategy, FOPS was effective method for all three students enhancing problem solving abilities and for generalizing and sustaining the problem solving.

Children's drawings are widely used in the diagnosis of children's psychology as a means of expressing inner feelings. This paper proposes a children's drawings-based object detection algorithm applicable to children's psychology analysis. First, the sketch area from the picture was extracted and the data labeling process was also performed. Then, we trained and evaluated a Faster R-CNN based object detection model using the labeled datasets. Based on the detection results, information about the drawing's area, position, or color histogram is calculated to analyze primitive information about the drawings quickly and easily. The results of this paper show that Artificial Intelligence-based object detection algorithms were helpful in terms of psychological analysis using children's drawings.

In this paper, an efficient prediction-based parallel simulation method using spatially partial simulation strategy is proposed for improving both the performance of the event-driven gate-level timing simulation and the debugging efficiency. The proposed method quickly generates the prediction data on-the-fly, but still accurately for the input values and output values of parallel event-driven local simulations by applying the strategy to the simulation at the higher abstraction level. For those six designs which had used for the performance evaluation of the proposed strategy, our method had shown about 3.7x improvement over the most general sequential event-driven gate-level timing simulation, 9.7x improvement over the commercial multi-core based parallel event-driven gate-level timing simulation, and 2.7x improvement over the best of previous prediction-based parallel simulation results, on average.

Successor representation (SR) 은 두뇌 내 해마의 공간 세포가 인지맵을 구성하여 환경을 학습하고, 이를 활용하여 변화하는 환경에서 유연하게 최적 전략을 수립하는 기전을 모사한 강화학습 방법이다. 특히, 학습한 환경 정보를 활용, 환경 구조 안에서 목표가 변화할 때 강인하게 대응하여 일반 model-free 강화학습에 비해 빠르게 보상 변화에 적응하고 최적 전략을 찾는 것으로 알려져 있다. 본 논문에서는 SR 기반 강화학습 알고리즘이 보상의 변화와 더불어 환경 구조, 특히 환경의 상태 천이 확률이 변화하여 보상의 변화를 유발하는 상황에서 어떠한 성능을 보이는 지 확인하였다. 벤치마크 알고리즘으로 SR 의 특성을 목적 기반 강화학습으로 통합한 SR-Dyna 를 사용하였고, 환경 상태 천이 불확실성과 보상 변화가 동시에 나타나는 2-stage 마르코프 의사결정 과제를 실험 환경으로 사용하였다. 시뮬레이션 결과, SR-Dyna 는 환경 내 상태 천이 확률 변화에 따른 보상 변화에는 적절히 대응하지 못하는 결과를 보였다. 본 결과를 통해 두뇌의 강화학습과 알고리즘 강화학습의 차이를 이해하여, 환경 변화에 강인한 강화학습 알고리즘 설계를 기대할 수 있다.

This paper investigates the effect of a deep learning-based system on data labeling task productivity by individuals with developmental disabilities. It was found that interventions, particularly those using AI, significantly improved productivity compared to self-serving task. AI interventions were notably more effective than job coach-led approaches. This research underscores the positive role of AI in enhancing task efficiency for those with developmental disabilities. This study is the first to apply AI technology to the data labeling tasks of individuals with developmental disabilities and highlighting deep learning's potential in vocational training and productivity enhancement for this group.
