Immersive content provides a differentiated and immersive experience from existing content. It is a type of content that stimulates various senses, such as vision, hearing, touch, smell, and taste, to allow users to experience the world as if it were real. Among them, holograms are a technology that creates three-dimensional images using light. Unlike traditional 2D images, holograms can provide a realistic experience. The three-dimensionality and depth of holograms make users feel a strong sense of space and presence, making them a promising next-generation content for expressing virtual worlds. This study aimed to analyze the suitability of hologram technology for immersive content and the correlation between storytelling in immersive content in this trend. To this end, we produced a holographic immersive content of Tchaikovsky's "Swan Lake," which has a narrative structure of rising action, climax, and falling action. In the production process, we used floating solar panels as a power source, considering the environmental aspect. We showed the produced immersive content to related experts and collected their opinions through semi-structured interviews. As a result of the analysis, we confirmed that holograms are an effective technology for enhancing the immersion of immersive content. We also confirmed that storytelling plays an important role in enhancing the immersion of immersive content.

A study on webGl efficiency in Unity servers was conducted. There are various ways to upload a build file made with Unity to a web server. In fact, to classify it that way, it would not be an exaggeration to say that there are as many developers as there are. In this paper, it is mainly classified into four types and introduced. First, there are ways to package and distribute the Unity project itself, distribute it as a standalone or mobile build, distribute it as a webplayer build, and distribute it as a WebGL build. I would like to briefly introduce each method, look at the simplest of them, the distribution method in WebGL, and study the efficiency of this method in detail. Through this study, we can use Unity for the first time to help people who are thinking of deploying servers or are interested in basic engines and server upload methods. In this paper, we will first introduce the simplest way of building WebGL, then explain and compare the four distribution methods, and finally compare them with the efficiency of the WebGL method. This will support opinions on efficiency.

Job-centered support for soldiers scheduled to be discharged or discharged is part of the military transition support policy and is a policy that supports them to return to society from the military and perform the role needed by the nation. In order to create a productive military service environment for young soldiers without career breaks, the Armed Forces Soldier Job Fair is held every year at KINTEX in Ilsan. This study proposed a Metaverse job fair for young soldiers of the MZ generation using the service design process and media prototype. During the research process, it was confirmed that young soldiers' interest in and need for employment is increasing, and the importance of employment support programs within the military is emerging, and the Armed Forces Soldier Job Fair Metaverse Hall utilizes the ZEPETO platform to solve consumer-centered problems. By producing a prototype, we proposed that soldiers who would like to participate in the job fair but find it difficult to do so due to unit conditions could participate through mobile devices without spatial or time constraints. As a result of the study, it is expected that job fairs using the Metaverse platform will contribute to increasing the possibility of productive military service for soldiers, improving the efficiency of military administrative work by utilizing digital technology, and spreading a positive image of military service.

Massively Multiplayer Online Role-Playing Game(MMORPG) attract thousand of concurrent users, leading to a surge in server requests. The massive requests results in contention on the game server, causing unexpected latency issues that undermine user experience. Delayed latency leads to user dissatisfaction and, ultimately, user churn. In this paper, we propose a multi-threaded game server design that provides stable response time by utilizing computing resources. And we study the performance of the design under various environments by configuring the approaches we implemented. The server consists of a socket system that helps communicate between clients and servers, a task system that handles changes in the status of user, and a synchronization system that allows users to receive the same game information. To prevent serious contention, both lock and lock-free algorithms for process synchronization are applied, and some parallel programming approaches such as visual processing are introduced.

User churn in games often arises due to inadequate game difficulty. To address this, non-player characters (NPCs) has been utilized to modulate difficulty according to individual game skill. Nevertheless, the effectiveness of solely NPC-based adjustments is limited since game difficulty is influenced by both NPCs and environmental factors. This paper introduces a novel method for dynamically tailoring game difficulty by adjusting in-game environments based on player behavior patterns in top-down shooter game. Through analysis of diverse user game play data, we find that factors within the game environment, such as the distribution of enemy characters and the arrangement of terrain, have a substantial influence on the level of difficulty. Furthermore, it has been observed that behavioral patterns of players show variations according to changes in the game environment. Using these analytical result, we devise an artificial neural network model that configures an environment that suit player behavior patterns. With the model, we figure out the user player pattern and control the difficulty dynamically by changing the environment factors. Through the experiments, we show that our method provides an appropriate level of difficulty for users to prevent user churn.

Distance is a fundamental definition in fields such as geometry, mathematics, and physics. Because it is a very fundamental metric, it is not easy to create a new definition. In this study, we analyze existing distance definition and propose to generalize Euclidean distance and Manhattan distance, which are mainly used distance metric in existing distance definition. We analyze the definition of Minkowski distance, which is previously used as a concept of generalization along with Chebyshev distance, and the disadvantages of using this distance metric. By introducing a new perspective that interprets the existing Manhattan distance as a distance measured in four axes rather than simply adding the distances in each axis direction, this research introduces a new distance metric in two dimensions. This is a metric that generalizes the Euclidean distance and the Manhattan distance, and the proposed distance metric is derived from a geometrical aspect and an algorithm for calculating it is presented. We applied the existing distance definition and compared the differences through the results of generating a Voronoi area by the shortest distance from randomly distributed points in two dimensions. It is expected that the proposed method can be applied and expanded to the field of various graphics algorithms that use the distance metric.

The gaming industry is experiencing rapid growth due to recent advances in technology. Game engines such as Unity and Unreal are being actively utilized. These game engines offer a variety of plugins to naturally extend the functionality of the engine. Among them, innovations in 3D graphics technology have made game characters more expressive and enhanced the user experience. However, traditional 3D modeling approaches can sometimes bring limitations and challenges. In particular there are problems with the representation of fine details when utilizing general photos through AI scanning. This paper aims to overcome these difficulties by designing and implementing a game 3D character generation framework using Stable Diffusion. By improving the creation process by utilizing concept art images without hairstyles, it enables fast and efficient character creation. The application of this framework allows for faster and more consistent character creation with fewer steps in the creation process and helps game developers to adapt characters to the engine more easily and quickly. In addition, we verified the effectiveness and scalability of the 3D game character data generated by Stable Diffusion by checking the animation behavior in the game engine.

With the recent advent of Metaverse, the character industry that reflects the characteristics of users' faces is drawing attention. there is a hassle that users have to select face components such as eyes, nose, and mouth one by one. In this paper, we propose a diffusion-based model that automatically generates characters from content human photographs. Our model generates user artistic characters by reflecting content information such as face angle, direction, and shape of a content human photo. In particular, our model automatically analyzes detailed information such as glasses and whiskers from content photo images and reflects them in artistic characters generated. Our network generates the final character through a three-step: diffusion process, UNet, and denoising processes. We use image encoders and CLIP encoders for the connection between style and input data. In the diffusion process, a collection of noise vectors is gradually added to a style vector to enable lossless learning of the detailed styles. All input values except for the style images are vectorized with CLIP encoders and then learned with noise style vectors in the UNet. Subsequently, noise is removed from the vectors through the UNet to obtain the artistic character image. We demonstrate our performance by comparing the results of other models with our results. Our method reflects content information without loss and generates natural high-definition characters.

The global PC game market is enjoying sustainable growth, and diverse grow types and quantities of games. Among the many, the theme of horror circulates in the market. Ahead of placing orders, the poster initiates the first exchange with the game, players and consumers, and affects buyers' behavior and cognition subject to its color. What is an eye-catching poster? Different games have different styles and philosophies, so it leads to a certain degree of variation in the poster design of each game. In order to study the common points of popular game color design. For the top 10 most acclaimed horror games on STEAM (PC), 5 to 6 color elements were mined from each poster for analysis and offered suggestions on poster design. First, in the color selection, more warm colors are on the list of recommendation, such as yellow, you can also choose cool colors such as blue. Second, high-saturation and high-brightness colors speak for better choice. The design of color is not absolute, and this thesis only analyzes the posters of commercially circulated and well-received horror games. It is hoped to provide insights for user-friendly interface design, support and understanding of user behaviors.
