In this paper, we implement a digital content that visualizes 33 Avalokitesvara-Bodhisattva according to the wishes of the public. The 33 Avalokitesvara-Bodhisattva is described in the Avalokitesvara-Bodhisattva tale that is found in the ancient literature "Memorabilia of the Three Kingdoms" as Tangible Cultural Heritage. Also, it is easily found in a wall painting of traditional Buddhist temples. The 33 Avalokitesvara-Bodhisattva is the saint of mercy that transforms into 33 various forms according to the wishes of the public. The Avalokitesvara-Bodhisattva tales deal with differences in the types of wishes of the public, and the tales have been speeded like wildfire among the people. So, in this paper, we classify them into 4 groups by the wishes (healing, security, academic achievement, disaster relief) of the public, and then analyze its symbolism and activity of the 33 Avalokitesvara-Bodhisattva. Also, we implement a 2D digital content that represents visually it according to the wishes of the public. Applications of the implemented visual content are as follows; development of character, game, and digital storytelling associated with traditional culture, education service for Buddhist doctrines, etc.

The video production, as a recording data about the archeological survey, has advantages to be visualized in actuality and historical fact presented objects with elements such as moving images, audio(voice) and text(subtitle). While the report with text and images such as photographs and drawings does not present exactly, the video production can record a concrete excavation process to be difficult of represent with former media. To make a practical use the video production in archeological surveys, the use dimension should be expanded to the entire archeological excavations and the shooting and editing work should be done by those video production-specialized staffs. Ultimately, when this video production device is used but also for the survey purposes but also for the education, exhibition, and even commercial purposes, it can have the substantial meaning as a survey tool.

In this paper, we present an algorithm which recognize hand shape in real time using only image without adhering separate sensor. Hand recognizes using edge orientation histogram, which comes under a constant quantity of 2D appearances because hand shape is intricate. This method suit hand pose recognition in real time because it extracts hand space accurately, has little computation quantity, and is less sensitive to lighting change using color information in complicated background. Method which reduces recognition error using principal component analysis(PCA) method to can recognize through hand shape presentation direction change is explained. A case that hand shape changes by turning 3D also by using this method is possible to recognize. Human interface system manufacture technique, which controls a home electric appliance or game using, suggested method at experience could be applied.

Satellite-derived data is collected by observing the Earth and is used in various fields such as national defense, natural disasters, location-based services, infrastructure, environment, energy, marine, and insurance. This study aims to present the virtuous cycle structure of the satellite information data industry and the business ecosystem model of the industry. As a research method, cases were collected and categorized from the following areas: literature, online, application, and content. The results show that the ecosystem model of the satellite information data industry provides an approach to content services in public and commercial areas, and develops various algorithmic technologies to facilitate content production and services at the level of complex general-purpose technologies. Second, in terms of content typology, satellite information data can be subdivided into monitoring content, urban space monitoring content, and satellite information content. Third, the consumption value of satellite content could be subdivided into informational value, environmental, social and governance (ESG) value, educational value, and content value. In order to expand the global content market, Korea will need to focus on creating an ecosystem for the satellite information industry and discovering differentiated content. It will also need to increase the popularization and accessibility of data to the general public and promote the Korean K-Satellite Information Data Industry ecosystem through government support, policy efforts, and policies such as establishing legal systems, increasing investment, and training human resources.

Recently, with the high interest of machine learning, the need for educational controllers to interface with physical devices has increased. However, existing controllers are limited in terms of high cost and area of utilization for educational purposes. In this paper, motion control controllers using brain waves are proposed for the purpose of students' machine learning applications. The brain motion that occurs when imagining a specific action is measured and sampled, then the sample values were learned through Tensor Flow and the motion was recognized in contents such as games. Movement variation for motion recognition consists of directionality and jump motion. The identification of the recognition behavior is sent to a game produced by an Unreal Engine to operate the character in the game. In addition to brain waves, the implemented controller can be used in various fields depending on the input signal and can be used for educational purposes such as machine learning applications.
