This paper explores the use of machine learning in game production to create goal-oriented, realistic animations for skeleton monsters. The purpose of this research is to enhance realism by implementing intelligent movements in monsters within game development. To achieve this, we designed and implemented a learning model for skeleton monsters using reinforcement learning algorithms. During the machine learning process, various reward conditions were established, including the monster's speed, direction, leg movements, and goal contact. The use of configurable joints introduced physical constraints. The experimental method validated performance through seven statistical graphs generated using machine learning methods. The results demonstrated that the developed model allows skeleton monsters to move to their target points efficiently and with natural animation. This paper has implemented a method for creating game monster animations using machine learning, which can be applied in various gaming environments in the future. The year 2024 is expected to bring expanded innovation in the gaming industry. Currently, advancements in technology such as virtual reality, AI, and cloud computing are redefining the sector, providing new experiences and various opportunities. Innovative content optimized for this period is needed to offer new gaming experiences. A high level of interaction and realism, along with the immersion and fun it induces, must be established as the foundation for the environment in which these can be implemented. Recent advancements in AI technology are significantly impacting the gaming industry. By applying many elements necessary for game development, AI can efficiently optimize the game production environment. Through this research, We demonstrate that the application of machine learning to Unity and game engines in game development can contribute to creating more dynamic and realistic game environments. To ensure that VR gaming does not end as a mere craze, we propose new methods in this study to enhance realism and immersion, thereby increasing enjoyment for continuous user engagement.

The purpose of this study is to compare the eighth-grade mathematics textbooks of Korea, Japan on the one hand, and those of the United States and England on the other, and to explore the implications for mathematics education in the East and the West. As a result, the dichotomy between the East and the West were set up with the sacrifice of the details. First, the textbook development and publication policies of the East are characterized as uniformity, and those of the West are diversity. Second, for the choice of content, the East and West can be represented by essential and discretionary respectively. Third, the physical appearance of Eastern textbooks is rather plain while that of the Western textbooks is colorful, Fourth, in terms of the characteristics of the content, the dichotomies between the East and the West are linear vs. spiral, content vs. context, formal abidance vs. metacognitive shift, and simple vs. realistic. Each of the Eastern and Western approaches has its own weak points as well as its strong points. For instance, textbooks In the West may help students realize how useful mathematics can be in their lives, but if the link between a mathematical concept and the corresponding real life situation is not made clear, sometimes students may not be able to completely grasp the mathematical concept. In turn, the Eastern textbooks may succeed In conveying ideas in an economical way, but they often fail to motivate students to follow the course. Therefore it is important to take a critical view of each approach. It is through a critical understanding of the differences between different cultures that we are able to learn from each other and to put the results of such comparative studies to better use in the future.

The sound dietary habit is formed in childhood, which is basic foundation for keeping health. The school foodservice is practiced to provide proper nutritions, to establish the sound dietary habit. Continuous evaluation and improvement are necessary to operate school foodservice effectively. This study was conducted to evaluate the quality of meals served in elementary school based on nutrient content, food diversity. A questionnaire was mailed to dietitian of each school requested for menus of one week. Menus served in 77 schools from each province and major cities in Korea were analyzed. The results of this study were summarized as follows; Compared to 1/3 of RDA for children, many schools provide lower amounts of energy, calcium and Vitamin A. Proportions of energy from carbohydrate, protein and fat were 59.64%, 17.43% and 20.11%, respectively and were not significantly different by the area, the foodservice system, and the number of persons served. NAR(nutrient adequacy ratio) were lowest for calcium(0.67) and Vitamin A(0.65). MAR(mean adequacy ratio) was 0.83. The results of comparison of NAR and MAR by the area, the foodservice system, and the number of persons served were similar to those of nutrient contents. Comparing foods served by the nutrient density were different by nutrient contents, NAR and MAR. Mean nutrient density per meal were higher in large cities than in small cities and rural area, in conventional than in commissary foodservice system. Mean number of dishes and food items per meal were 5.86 and 19.87, respectively. The mean of total quantity of each food group per meal was 352g. The mean of total quantity of each food group per meal were higher in small cities and rural area than in large cities, in commissary than in conventional foodservice system. This study is based only on served menus, and the evaluations of meals based on actual consumption of children are needed. These results suggest that in order to improve the quality of school food service, realistic standard should be suggested and basic study should be done continuously.
