현대사회와 미래사회는 가속화되어지는 IT기술에 의해서 융합되어진 작업의 효율 및 성능의 발전이 이슈화되고 있다. 따라서 1990년대부터는 군사 및 재활분야와 함께 제조업 및 유통업 등 전반적인 산업 모두에서 근력보조기구에 대한 연구가 활발히 진행되고 있다. 과거에는 일반인이 무거운 짐을 운반하는 것을 완전한 로봇이 대체하거나 몸이 불편한 사회적 약자가 휠체어 및 지팡이 또는 전동 휠체어와 같은 보조 개념이 아닌 완전한 대체의 개념을 가지고 있었다. 그러나 웨어러블이 대두됨에 따라 기계와 인체가 합쳐지는 상호작용 근력보조기구가 탄생했다. 근력보조기구는 힘/토크 센서를 통한 인간과 로봇간의 상호작용에 의해 인간의 다양한 상지 및 하지 동작을 구현할 수 있는 근력 강화용 웨어러블 로봇 등이 있다.

다중 로봇 시스템에는 multiple arms, 다족 보행, 다중 손 등이 있다. 이러한 시스템들은 여러 개의 부속체인 로봇들이 물체를 파지하는 특징을 지닌다. 그러나 이러한 적용분야에서 물체를 파지하는 내력에 대한 개념은 각각 다르게 해석되어져 왔음을 살펴볼 수 있다. 본 논문에서는 내력은 로봇 말단에서의 움직임에는 영향을 주지 않지만, 정적 평형을 이루며 내부적으로 작용하는 힘과 모멘트라고 정의 하였고, 이러한 개념이 현존하는 다중 로봇 시스템에 일반적으로 적용할 수 있음을 제시한다. 또한 최소 놈 해에 있어서 내력이 존재하지 않는 조건과, 내력을 구성하는 기저를 밝혔고, 다양한 다중 로봇 시스템의 내력 해석에 사용할 수 있음을 제시하였다.

It has been 20 years since the cultural contents were newly emerged in the late 1990s and grown in our society. However, efforts to establish culture contents concept and to establish cultural contents as a separate discipline are relatively poor. There may be various reasons, but the most important thing is that it failed to cover the broad sense of the word 'cultural contents' and to present a key concept through the core. Therefore, this study examined the possibility of securing the conceptual resources necessary to lay the foundation for cultural contents within play, under the premise that cultural contents should be play studies in the 21st century. In order to do this, this paper examined the meaning of play in each of the three conceptual categories, ie, mimesis, aesthetics, and power, which are deemed to be related to the meaning of cultural contents that we currently use. As a result, it has been confirmed that play is used in various ways in connection with various concepts such as emotion, art, percept, cognition, education, coincidence, power, hegemony, class, religion, ritual. These various uses of play concept can give cultural contents researchers an opportunity to study cultural contents from a play perspective.

It is well known that Deleuze began his philosophical work from researching the biographies of many predecessors' such as D. Hume, Lucretius, I. Kant, B. Spinoza, F. W. Nietzsche, H. Bergson, and etc. Among them, especially Spinoza, Nietzsche, and Bergson constitute a foundation supporting the whole idea of Deleuze. He declared that the goal of his early biographical work is a theme converging the identity of two philosophers, Spinoza and Nietzsche, and it shows that these two philosophers had such a huge significance to Deleuze, at least by then. However, we may point out two issues here. The first is why Deleuze, who is recognized as a philosopher of 'difference', deals the identity. The other issue is, what kind of identity exists between the two philosophers, Spinoza and Nietzche. In a common sense, their ideas contradict to each other. Spinoza puts God at the center of his philosophical system, whereas Nietzsche declared 'God is dead'. Though Nietzsche expressed a concurrent opinion with Spinoza at first, it is well known that he turned his side against him soon after and criticized him sharply. There is a conflict at the core of this criticism concerning the existence or non-existence of God. Many think that Spinoza, however, cannot be free from the argument that his philosophy allows a possibility of atheism. Deleuze, who also called Spinoza an atheist, suggested a new viewpoint of the philosophy of Spinoza based on his attribution to the concept of 'power'. On the other hand, Deleuze reinterpreted Nietzsche, where he analyzed 'the will to power' in a totally inventive way. Likewise, the reciprocal communication of ideas connected by the concept of 'power' gives a foundation of identifying the two philosophers to Deleuze. In this paper, considering this reciprocal communication, I intent to reveal the foundation of identity of the two philosophers, Spinoza and Nietzsche, and as a result, investigate what the concept of identity means to Deleuze, the philosopher of difference. Furthermore, we will also take a look at how Deleuze presents a new perspective on the conflict on the existence of God of the two philosophers in the process of validating the identity.

The purpose of this study was to identify the factors that constitute masculine norms of masculine in Korean society. The definition of masculinity was to conform to the male-dominated standard formed socially and culturally. The results of in-depth interviews with 20 male participants were used for a concept mapping analysis to explore the configural representations of Korean masculine norms. After extracting the key sentences related to masculine norms, the participants sorted the 55 key sentences based on similarities and assessed the importance, which was then analyzed with multidimensional scaling method and cluster analysis. The result showed two dimensions, one representing social-personal domain and the other implying dominance-support domain as well as six clusters of caregiver, leadership, emotion suppression, job ability and organizational social adaptation, Expects the masculine abilities, power and control. Finally, the implications of this study, limitations, and the suggestions for future research were discussed.

To achieve the best performance, the concept of drag reduced and power increased Human Power Aircraft(HPA) was presented by analyzing the HPAs in the world. To participate the '2012 HPA competition' in Korea, the streamlined fuselage and the simultaneous use of hands and feet were introduced. Furthermore the CFD analysis and power unit design were performed to verify the concept. In order to make the best use of streamlined fuselage effect, the fuselage shape design is important and to supply the hand power to the power unit, the control system design is important, also the test flight is required for validation.

In this study, nonlinear static aeroelastic analysis system for a high-aspect-ratio wing are developed using the transonic small disturbance (TSD) and large deflection beam theory and validated. For the coupling between fluid and structure, the transformation of displacement from the structural mesh to aerodynamic one is performed by the shape function of the beam finite element and the inverse transformation of force by work equivalent load concept. Also, for the static aeroelastic analysis of the wing the use of TSD aerodynamics are justified. The validation of the system includes one of the efficient transformation methods of force and displacement.

Nowadays computer graphic softwares have opened a lot of potential by providing parametric modeling and generative algorithms which are useful not only to describe various geometrical shapes but also to implement a designer's intent in terms of modules systematically. This study has proposed a way of developing a module for generating preliminary structural configuration using such potential computer graphics. Especially parametric modeling and generative algorithm are utilized to define various design alternatives, and moreover use of dynamic graphics enables designers to generate a structural form on one side and a force flow diagram correspondingly provided on the other. This ultimately leads to rational preliminary design of a structural form considering its force flow.
