The paradigm of contemporary times became different from paradigm of modem times. The change of paradigm is caused by the side effect of paradigm of pre-times. It could be said that contemporary paradigm is pluralism. In the forms of contemporary building and interior design, the informal form is the result of pluralism. This study is researching and analyzing the informal design tendency in the interior space composition of contemporary architecture. the 1950's free form movement, 1960's Informal movement and pluralism after 1970's affected the latest informal forms. The tendencies of contemporary informal design are organic-degital tendency and deconstructive tendency. Along this two kinds of tendencies, I studied the specific characters in expression and analyzed some natural-degital, deconstructive building.

Recent years with the development of artificial intelligence and the success of the deep model, they have been deployed in all fields of computer vision. Action recognition, as an important branch of human perception and computer vision system research, has attracted more and more attention. Action recognition is a challenging task due to the special complexity of human movement, the same movement may exist between multiple individuals. The human action exists as a continuous image frame in the video, so action recognition requires more computational power than processing static images. And the simple use of the CNN network cannot achieve the desired results. Recently, the attention model has achieved good results in computer vision and natural language processing. In particular, for video action classification, after adding the attention model, it is more effective to focus on motion features and improve performance. It intuitively explains which part the model attends to when making a particular decision, which is very helpful in real applications. In this paper, we proposed a 3D dense convolutional network based on attention mechanism(ADD-Net), recognition of human motion behavior in the video.

As recent virtual reality technologies provide a more natural three-dimensional interactive environment, users naturally learn to explore space and interact with synthetic objects. The virtual reality researcher develops a technique that realizes realistic sensory feedback to get appropriate feedback to sense input behavior. Although much recent virtual reality research works extensively consider the human factor, it is not easy to adapt to all new virtual environment contents. Among many human factors, distance perception has been treated as very important in virtual environment interaction accuracy. We study the experiential virtual environment with the feature of the virtual object connected with the real object. We divide the three-dimensional interaction, in which distance perception and behavior have a significant influence, into two types (whole-body movement and direct manipulation) and analyze the real and virtual visual distance perception heterogeneity phenomenon. Also, we propose a statistical correction method that can reduce a near-body movement and manipulation error when changing the interaction location and report the experiment results proving its effectiveness.

This study was performed to investigate the effects of clutch adaptation on the mandibular rotational torque movement in normal people. 69 dental students were selected for the study. Their mean age were 23.6 years and they did not present any signs and symptoms of temporomandibular disorders. $BioEGN^{(R)}$ with $Rotate^{(R)}$ program was used to observe and record the amount of mandibular rotational torque on protrusion, on right excursion, on left excursion, and on comfortable wide opening movement. The natural tooth contact movement and the movement with clutch were performed in the above four each mandibular movement. Clutch was made by the method used in $Pantronic^{(R)}$ clutch fabrication. Distance of slant frontal which was translatory trajectory in frontal plane and degree of rotational torque in horizontal and in frontal plane were recorded. The data obtained were processed with SPSSWIN program and the results were as follows : 1. Distance of slant frontal in each mandibular movement generally increased with clutch. 2. Degree of rotational torque in horizontal and in frontal plane on protrusion and on lateral excursions did not increase with clutch, but the degree on wide opening increased with clutch. 3. Degree of rotational torque in horizontal plane on protrusion and on lateral excursions did not show any difference between right and left side, but the degree in frontal plane on protrusion and on lateral excursions showed significant difference between right and left side. 4. Total amount of rotational torque from right and left sides on protrusion and lateral excursions were not increased with clutch, but the degree on wide opening movement was increased with clutch. And in this case, degree in horizontal plane was larger than that in frontal plane. 5. Correlation between total amount of rotational torque in horizontal plane and that in frontal plane were highly significant on protrusion and on lateral excursions with or without clutch, but the significant correlation on wide opening without clutch became not significant with clutch.

The purpose of this study is to understand the characteristics of Aristotle's view of nature that is, the static view of the universe, and find implications for education. Plato sought to interpret the natural world using a rational approach rather than an incomplete observation, in terms of from the perspective of geometry and mathematical regularity, as the best way to understand the world. On the other hand, Aristotle believed that we could understand the world by observing what we see. This world is a static worldview full of the purpose of the individual with a sense of purposive legitimacy. In addition, the natural motion of earthly objects and celestial bodies, which are natural movements towards the world of order, are the original actions. Aristotle thought that, given the opportunity, all natural things would carry out some movement, that is, their natural movement. Above all, the world that Plato and Aristotle built is a static universe. It is possible to fully grasp the world by approaching the objective nature that exists independently of human being with human reason and observation. After all, for Aristotle, like Plato, their belief that the natural world was subject to regular and orderly laws of nature, despite the complexity of what seemed to be an embarrassingly continual change, became the basis of Western thought. Since the universe, the metaphysical perspective of ancient Greece and modern philosophy, relies on the development of a dichotomy of understanding (cutting branches) into what has already been completed or planned, ideal and inevitable, so it is the basis of traditional teaching-learning that does not value learner's opinions.

Recently, motion capture has become one of the most promising technologies in animation. Realistic motion data can be captured by recording the movement of a real actor with an optical or magnetic motion capture system. This paper deals with motion editing by a geometric mean filter. Since the captured motion has some noises that cause a jerky motion, it needs a smoothing process to make it natural. A geometric mean filter is proposed to produce natural motions without jerky motions. Experimental results show that the geometric mean filter can effectively remove noises that cause a jerky motion and it can guarantee the most natural motions among various spatial filters. This method could be applied to the various fields such as real time animation, virtual reality applications, 3D applications, and etc.

The genetic polymorphism and relationship among 14 Zelkova serrata registered as the natural monument in Korea were investigated using RAPD markers. N-J tree indicated that individuals in Kangwon-do were clustered and those in Yangam-gun and Damyang-gun of Chollanam-do were done closely. However, all the others were not agreed with the geographical distribution. Maybe this discordance was resulted from their movement by human being than any biological factors. The polymorphic percentages among individuals were from 77.8 to 100. From the high polymorphism, it was supposed that existing natural monuments were independently originated in the ancestors of long differentiated populations.

In this study, to study the aesthetic properties of the Italy fashion, the internal fashion contents are defined according to the cultural characteristics of Italy and based on the definition, the external features are investigated. The cultural characteristic was analyzed based on the reference literatures on the Italy culture. The aesthetical properties of the contemporary Italy fashion can be analyzed as follows: ${\cdot}$ Functionalism is a feature showing the Italian cultural environment where the genuine humanism is retained. It enables the practical designs by applying details and materials that wouldn't put a limit to the movement of the human body. ${\cdot}$ Naturalism focuses on the natural beauty of the human body without any artificial forms or exaggerated ornaments. Natural texture or materials are used to express the human body itself, or to emphasize the natural aesthetic effects flowing with the human body. ${\cdot}$ Localism is the expression of folk spirit affected by the natural environment. It expresses local atmosphere by unique craftsmanship in material, pattern, color and details. Based on this result, the aesthetic properties of the contemporary France fashion, examined through ${\Iceil}$A Cultural Approach to the Aesthetic Characteristic of the 20th Century French Fashion${\rfloor}$ and those of the contemporary Italy fashion are compared.

Numerical modeling and scenario composition are needed to characterize the geological environment of the disposal site and analyze the long-term evolution of natural barriers. In this study, processes and features of the hydro-mechanical behavior of natural barriers were categorized and represented using the interrelation matrix proposed by SKB and Posiva. A hydro-mechanical coupled model was evaluated for analyzing stress field changes and fracture zone re-activation. The processes corresponding to long-term evolution and the hydro-mechanical mechanisms that may accompany critical processes were identified. Consequently, practical numerical methods could be considered for these geological engineering issues. A case study using a numerical method for the stability analysis of an underground disposal system was performed. Critical stress distribution regime problems were analyzed numerically by considering the strata's movement. Another case focused on the equivalent continuum domain composition under the upscaling process in fractured rocks. Numerical methods and case studies were reviewed, confirming that an appropriate and optimized modeling technique is essential for studying the stress state and geological history of the Korean Peninsula. Considering the environments of potential disposal sites in Korea, selecting the optimal application method that effectively simulates fractured rocks should be prioritized.
