Purpose: We aimed to investigate trunk angle and muscle activation of the extremity and back to evaluate the effect of chest compression on work-related musculoskeletal disorders in 119 emergency medical technicians (EMTs). Methods: Eighteen 119 EMTs performed 2-minute chest compression without interruption on a cardiopulmonary resuscitation manikin, during which we measured changes in the trunk and shoulder joint angles, muscle activation (triceps brachii, biceps brachii, erector spinae, gluteus maximus, pectoralis major, rectus abdominis, and rectus femoris) and chest compression accuracy. Results: The decrease in trunk angle by trunk muscle activation was the highest in event 2, the major direction of chest compression. Both shoulder joint angles had no significant difference. Muscle activation of the triceps brachii (p < .01), biceps brachii (p < .05), rectus abdominis (p < .05) and rectus femoris (p < .01) significantly increased during the compression phase compared with the decompression phase, with the rectus femoris showing an increase of 19%. Muscle activation of the erector spinae significantly increased in the decompression phase compared with the compression phase (p < .01). Conclusion: 119 EMTs mainly use the triceps brachii, biceps brachii and pectoralis major muscles during chest compression.

This study is a study on the development of board games using local cultural contents. As a prior study related to this study, basic research on board game development, research on cultural products based on cultural heritage, and storytelling development research using local cultural and tourism resources were considered. Among them, for the main purpose of board games and development process, discussions were conducted on the research methodology of Lee Dae-woong and Oh Seung-taek (2004). As a result, it was possible to successfully proceed with planning meetings, proposal preparation, board game design, board game 3D graphic production process, and prototype development. What is peculiar is that characters (dried persimmons, strawberries, jujube, and salted seafood) containing Nonsan's unique regional characteristics were searched and utilized. In addition, major cultural heritages such as Donamseowon Confucian Academy and Gwanchoksa Temple, designated as Nonsan-si cultural properties, were combined with important treasure hunt contents of board games to enhance interest and education at the same time. The theme of this paper, Nonsan, Finding Lost Treasure, is a new educational alternative that can solve the problems of computer games, and has the advantage of having the nature of community leisure play, not individual play. Based on this board game development research in the future, we intend to expect the results of game production using cultural elements from other regions.

A term 'Wolabal' which is an abbreviation of the words, in South Korea means the balance between work and life. The term reflects on people's thoughts to seek for their happiness these days. In fact, they think that the quality of the life is more valuable than any other things on their lives, reflecting on the issues caused by modern societies. 'Wolabal' has emerged as an alternatives to solve the social issues like economic recession, high unemployment rate, aging society, low birth rate and etc. However, in order to establish 'Wolabal' as a culture the comprehensive agreement between an individual and society should be considered first. In society, the system or policies to forster cultural business should be settled while in individual, it is necessary to change the way they think about their work and the qualities of their lives. From this view we have to focus on the relationship between their work and leisure. On the relationship between their work and leisure we should understand that the relationship is not conflicted but co-exists and understanding the real meaning of the relationship is critical in balancing between work and life. The recognition to the labor which has been from the past would give not only the meaning of individual survival but the one of their whole lives. Despite this, modern society has faded away the real meaning of labor because it has focused on the mass manufacturing and sometimes the long-termed economic sluggish has emerged. This trend has made people think about their lives and seek for their lives' real value.

Recently, as living of people becomes economically liberal, people's interests are being directed to enjoying leisure and finding fun. The design area is not exceptional from this change and thus fun elements are working as important purchase factors when people are purchasing goods in addition to intrinsic uses of the goods. Along with the development of cutting-edge technologies, other manufacturing industries like electronics, automobiles etc are swiftly responding to this trend, but the furniture industry that has been perceived as a relatively low technical industry is not at all prepared for this trend. Here, this thesis is to suggest a direction for our furniture industry to go by proposing many potentials to apply fun elements to furniture through surveys of design cases addressing fun in other areas. The surveys made in this study are largely divided into the fun in the aspect of perception and the fun in the aspect of awareness. First, the fun in the aspect of perception of furniture can be experienced through the assembling of D. I. Y. furniture and this requires studies and efforts of developers in order to enable people to enjoy the processes of assembling as a sort of 'play' without feeling a burden in the processes of assembling. Second, the fun in the aspect of awareness of furniture can be created by boldly introducing new technologies and materials from other industrials and this includes adding other functions than the intrinsic use of furniture such as containing things.
