In this paper, we propose a new framework that calculates the user's hand motions using a Leap Motion device, and uses this to practice and analyze arm muscles as well as juggling motions. The proposed method can map the movement of the ball in a virtual environment according to the user's hand motions in real time, and analyze the amount of exercise by visualizing the relaxation and contraction of the muscles. The proposed framework consists of three main parts : 1) It tracks the user's hand position with the Leap Motion device. 2) As with juggling, the action pattern of the user throwing the ball is defined as an event. 3) We propose a parabola-based particle method to map the movement of a juggling shape to a ball based on the user's hand position. As a result, using the our framework, it is possible to play a juggling game in real-time.

The purpose of this study was to examine the meaning and essence of the life of elderly men living alone in public rental housing. Among the phenomenological study methods, the present study used the analysis method proposed by Giorgi(2009). The study participants included 10 elderly men living alone in public rental housing who were recruited through network sampling. The research data were collected through in-depth interviews conducted twice for each person. The results showed that living alone as an elderly man is likened to standing against cold wind out in the wilderness of the world, with living alone deemed a power game between life and death. For the participants, public rental housing is a fence that separates them from the world-the final station of a wandering life. For common people, public rental housing is a stable fence, but for the participants, it is the location of a double-edged solitary life out in the wilderness where the instincts for survival and death play a tug of war. Based on the study findings, the researcher discussed and provided suggestions for psychological housing stability, the disparagement of the elderly in mass media, and countermeasures against psychological isolation.

This study is aimed to examine what school sports club activities mean to middle school students. To attain this objective, this study first investigated what kinds of peer culture school sports club activities form, and second, what kind of time school sports club is for the students. For the research method, a qualitative research method was employed combining in-depth interview and participatory observation. The results showed that first, the students were creating the peer culture of games, communication, and relaxation through school sports club activities. Though fighting sometimes, the boy students were really enjoying sports games with their friends according to their own rules. On the other hand, girls were enjoying the relationship with friends, more focusing on communication and relaxation than on playing sports game itself. Second, the students thought of school sports club activities as an exit. Those students who lacked leisure time regarded school sports club activity as a time to play with friends, to escape from the pressure of good grades, and different from physical education.

Spontaneous rupture of the extensor pollicis longus (EPL) tendon can occur in the 3rd extensor compartment after a distal radius fracture involving Lister's tubercle, steroid injections, or rheumatoid arthritis. We report a case of spontaneous rupture of the EPL tendon in a 26-year-old male patient who played a rhythm game, which requires repetitive wrist motions to play the drums. We also provide a comprehensive literature review along with the case report. From the authors' point of view, excessive and repetitive motion of the wrist, as shown in our case, can be a potential cause of spontaneous rupture of the EPL tendon.

The importance of combat drones has been highlighted through the recent outbreak of the Russia-Ukraine war. The combat drones play a significant role as a a game changer that alters the conventional wisdom of traditional warfare. Many pundits expect the role of combat swarm drones would be more crucial in the future warfare. In this regard, this paper aims to analyze the development of artificial intelligence-enabled combat swarm drones. To transform the human-operated swarm drones into fully autonomous weaponry system our suggestions are as follows. Developments of (1) AI algorithms for optimized swarm drone operations, (2) decentralized command and control system, (3) inter-drones' mission analysis and allocation technology, (4) enhanced drone communication security and (5) set up of ethical guideline for the autonomous system. Specifically, we suggest the development of AI algorithms for drone collision avoidance and moving target attacks. Also, in order to adjust rapidly changing military environment, decentralized command and control system and mission analysis allocation technology are necessary. Lastly, cutting-edging secure communication technology and concrete ethical guidelines are essential for future AI-enabled combat swarm drones.

When culture took large part in industrial area, every country has tried to utilize own cultural contents for educational or commercial purpose and the various cultures and histories are recognized as a main concept or subject so that a number of scholars who study history increase. In video game field, special characteristics of interface that audiences participate in the game to complete story-telling is considered as efficient material for learning process. As observed above, it is important to analyze the games that every country makes and export to the world in which the video games is understood as a play of human in general. This Paper has firstly analyzed the most favorite historical games developed in Korea, the USA, Japan, Taiwan and Germany from 1980 to 2005 and secondly, compared that wars and historical origin appears in game scenario, a world view and background story and finally after point out the preferable era and genre of the countries then propose the promising way of design for historical video games. In the process of analysis of a view and heroes in historical games, we compared the real persons, the real historical events and novel in which 11.8% only employed the real persons in 8 out of 68 games. Also the real history and background story are appeared in 37 games which is 54.4% of them. We discovered that the main material that is popular for each country is the historical backing rather than real persons where the favorite historical background is chosen at which they are proud of; 3-Throne era with strong ancient Gogurye for Korea, the 1st and 2nd World Wars and the Independence War for the USA, the tide of war around Middle age for Japan, ancient history of Europe for Germany. The favorite age for video games is Ancient times with 37 games for 54.4%, Middle Age with 7 games fer 10.3%, the prehistoric age with 5 games for 7.35%, remote age with 1 for 1.47%, while current historical games favor Ancient or Modern Age.

In recent years, new media art is developing to play its roles as a means of remediation to overturn, reuse, and alter the old technologies rather than technology-dependent art to accept new technologies and use them as artistic tools. Here, the concept of new should mean looking at the old technologies in an indirect way and finding new meanings in them rather than presenting new technologies. The starting point of this study was the concept of spatialization in which the concept of new media art would externalize games from inside to outside the screen in gamification-applied spaces. Participatory new media art adds a platform for viewer's participation and utilizes the entire space of the exhibition hall instead of allowing for simple viewing at the exhibition hall. The study focused on the changes and phenomena in the process of games belonging to the artistic space through the interactivity of gamification. Here, the premise was that gamification meant the "spatialization of games." The study examined several cases of games being altered in the spatialization process to figure out interactivity for viewers and developmental directions for interface design at a gallery.

Nowadays, display-contents are developing to an informative environment. that is under the logic of the media operating system. To perceive the media-environments and produce the cultural contents, the cultural designers seek to understand a skin structure from making up for shape. To appreciate operating system in data and database is not only systematization of form and contents of visual contents but also variety contents into multiple-platform and integrative environments. These days, the spectacle exhibition try to express for their surface design between algorithm of data and database. the information is expressing aesthetic which means presents the integrated contents through the play instinct environment to end-user. That was given web or game to participation is developing with the cellular device and ubiquitous computing system. in the linear perspective, the end-user should be immerse more and more hyper-simulation system because of the operating algorithm of database. To do this, human have need to get the information-ability from multi-platform society. In the virtual environment, database offer the experience of an unheard-of event to end-user that prepare the participants the circumstances priority of signifiers. To do that already based on a fixed sensibility endow with narrative of the freshness- experience.
