Game graphics provide players with a sense of immersion, leading to active participation. This paper aims to analyze the mythological meaning for symbolic design of game skill visual effects that reproduce the narrative and the worldview of games borrowing myths. The research method classified the visual effect image into a symbol of the form of a universal archetype representation and a symbol of color expressing the narrative in the game, and analyzed it by applying Roland Barthes' semiological scheme. Through this study, it was possible to analyze the meaning of visual effects as a mythical meaning that can be universally sympathized and an implicit meaning that symbolizes the narrative of the game. The symbolic expression of the visual effect, which reproduces the narrative of the game reflecting the myth, can induce players to engage and participate, and the design direction was intended to provide the visual effect to have a unique symbolism that reflects the game's mythical worldview of the game.

This paper proposes an ultrasound vessel-pattern imaging algorithm with low computational complexity. The proposed imaging algorithm reconstructs blood-vessel patterns by only detecting blood flow, and can be applied to a real-time signal processing hardware that extracts an ultrasonic finger-vessel pattern. Unlike a blood-flow imaging mode of typical ultrasound medical imaging device, the proposed imaging algorithm only reconstructs a presence of blood flow as an image. That is, since the proposed algorithm does not use an I/Q demodulation and detects a presence of blood flow by accumulating an absolute value of the clutter-filter output, a structure of the algorithm is relatively simple. To verify a complexity of the proposed algorithm, a simulation model for finger vessel was implemented using Field-II program. Through the behavioral simulation, it was confirmed that the processing time of the proposed algorithm is around 54 times less than that of the typical color-flow mode. Considering the required main building blocks and the amount of computation, the proposed algorithm is simple to implement in hardware such as an FPGA and an ASIC.

This study explores role of self-efficiency in the career activities of marriage immigrant women. It is expected that self-efficiency would contribute to marriage immigrant women helping them to overcome the difficulties of their lives spontaneously and keep on their careers. For this, it was conducted that in-depth interview with seven marriage immigrant women. Conclusion was classified into two parts as following. The conclusion is from whether marriage immigrant woman has self-efficiency in her career purpose and career barrier. First, in the conclusion of career purpose, higher self-efficiency leads to constant career fulfillment and positive self image and lower self efficiency gives rise to absence of neighboring subgoal and discontinuity or lagging of personal career. Second, in the conclusion of career barrier, higher self-efficiency person would consider career barrier as an object to get over. On the contrary, lower self-efficiency person could not find the proper strategies to deal with career barrier and conform to the barrier and give up the career.

Background: In modern society, the use of computers accounts for a large proportion of our daily lives. Although substantial research is being actively conducted on musculoskeletal diseases resulting from computer use, there has been a recent surge in interest in improving the working environment for prevention. Objects: This study aimed to examine the effects of posture correction feedback (PCF) on changes in neck posture and muscle activation during computer typing. Methods: The participants performed a computer typing task in two sessions, each lasting 16 minutes. The participant's dominant side was photographed and analyzed using ImageJ software to verify neck posture. Surface electromyography (EMG) was used to confirm the participant's cervical erector spinae (CES) and upper trapezius muscle activities. The EMG signal was analyzed using the percentage of reference voluntary contraction and amplitude probability distribution function (APDF). In the second session, visual and auditory feedback for posture correction was provided if the neck was flexed by more than 15° in the initial position during computer typing. A 20-minute rest period was provided between the two sessions. Results: The neck angle (p = 0.014), CES muscle activity (p = 0.008), and APDF (p = 0.015) showed significant differences depending on the presence of the PCF. Furthermore, significant differences were observed regarding the CES muscle activity (p = 0.001) and APDF (p = 0.002) over time. Conclusion: Our study showed that the feedback system can correct poor posture and reduces unnecessary muscle activation during computer work. The improved neck posture and reduced CES muscle activity observed in this study suggest that neck pain can be prevented. Based on these results, we suggest that the PCF system can be used to prevent neck pain.

The purpose of this study is to analyze how the movie <The Book of Fish> (2021) represents Joseon, which is slowly collapsing with the Neo-Confucian order of the 19th century shaking, and to discuss its meaning. Prior to the analysis, the analysis framework of the historical drama was presented considering the narration characteristics of the historical drama. Using the analysis framework of historical dramas, we confirmed that <The Book of Fish> is representing the image of Jeong Yak-jeon and Jang Chang-dae living their lives as independent individuals between the limitations and possibilities of the times based on the plot structure of the narrative of exile. Through the central memory and surplus memory created through plot and style elements such as contrast between black and white and color images, voice-over narration, chinese poetry subtitles and music, the film asks us universal questions about what it takes to live as an independent individual.

In the era of globalization, universal values and empathy are analyzed as important factors in the success of media content. In this context, the perspective of interculturalism is meaningful in K-culture discourse. The TV drama <Itaewon Class> presented a storytelling structure in which the existing order was overturned and new values triumphed. This concept has led to great success in the global market. First of all, it shows multiculturality through the symbolic space of Itaewon. It reproduces people who have various cultural differences in various standards. Characters with diverse values realize intercultural values through cultural dialogue. Such storytelling is evaluated as something that can be widely accepted by people around the world. Interculturalism enables us to seek the direction of sustainable Korean Wave.

In this paper, we propose a method for diagnosing ball bearing vibration using transfer learning. STFT, which can analyze vibration signals in time-frequency, was used as input to CNN to diagnose failures. In order to rapidly learn CNN-based deep artificial neural networks and improve diagnostic performance, we proposed a transfer learning-based deep learning learning technique. For transfer learning, the feature extractor and classifier were selectively learned using a VGG-based image classification model, the data set for learning was publicly available ball bearing vibration data provided by Case Western Reserve University, and performance was evaluated by comparing the proposed method with the existing CNN model. Experimental results not only prove that transfer learning is useful for condition diagnosis in ball bearing vibration data, but also allow other industries to use transfer learning to improve condition diagnosis.

In this paper, we propose a data augmentation method based on CNN(Convolutional Neural Network) learning for efficiently obtaining concrete crack image datasets. Real concrete crack images are not only difficult to obtain due to their unstructured shape and complex patterns, but also may be exposed to dangerous situations when acquiring data. In this paper, we solve the problem of collecting datasets exposed to such situations efficiently in terms of cost and time by using vector and thickness-based data augmentation techniques. To demonstrate the effectiveness of the proposed method, experiments were conducted in various scenes using U-Net-based crack detection, and the performance was improved in all scenes when measured by IoU accuracy. When the concrete crack data was not augmented, the percentage of incorrect predictions was about 25%, but when the data was augmented by our method, the percentage of incorrect predictions was reduced to 3%.
