Artificial intelligence in the game is mainly used to determine patterns of behavior of NPC (Non Player Character) and the enemy, path finding. These artificial intelligence is implemented by FSM (Finite State Machine) or Flocking method. The number of NPC behavior in FSM method is limited by the number of FSM states. If the number of states is too small, then NPC player can know the behavior patterns easily. On the other hand, too many implementation cases make it complicated. The NPC behaviors in Flocking method are determined by the leader's decision. Therefore, players can know easily direction of movement patterns or attack pattern of NPCs. To overcome these problem, this paper proposes agonistic behaviors(attacks, threats, showing courtesy, avoidance, submission)in animals to apply for the NPC, and implements agonistic behaviors using Unity3D engine. This paper can help developing a real sense of the NPC artificial intelligence.

As the demand of the consumer for high-sense clothing, relation with materials is becoming important even in clothing construction. Especially, the cutting angle of materials is becoming an crucial element in the formation of silhouette, and drape of Hem line, of skirts. Accordingly, in this study, Hem line shapes between real clothing and 3D virtual clothing of "i-Designer" were analyzed by manufacturing semi-flare skirts of polyester 100% according to a cutting angle, and the results are as follows. As a result of comparison of silhouette between the real clothing and the virtual clothing, the real and the virtual have a similar feeling regardless of a cutting angle. In case of drape shapes, both the front and the lateral side were represented in almost similar shapes. The back side, however, the real and the virtual showed a great difference in case of grain direction. And in the whole silhouette, the real and the virtual were represented similarly. It could be known that with regard to Hem-line drape shapes between the real clothing and the virtual according to a cutting angle, the real clothing is represented in a location farther from the body than the virtual clothing and, the location or number of node was similarly showed in the real and the virtual.

The purpose of this study is to provide ideas for the development of bag design by analyzing the expression types and aesthetic formativeness of modern bag design using tassels and fringe given the newtro trend pursuing analog sensitivity in modern society. The methods and scope of this study are as follows. First, the related literature and internet data were reviewed in order to examine the expression types and characteristics of the bags of the West and East. Next, the definition and characteristics of tassel and fringe decoration in terms of the history of clothing were analyzed. Finally, the expression types and aesthetic formativeness of tassels and fringe were derived through the analysis of modern bag design shown in the fashion collections since 2010. The bags decorated with the tassels and fringe bring a variety of visual effects depending on the attachment position, direction and material composition, concentrating the gaze and radiating original style. In this study, the expression of tassels and fringe in modern bag design was classified into three types: surface decoration, shape variability, and object combination. Next, the aesthetic formativeness of modern bag design using tassels and fringe as decorative elements appeared through the mixture of heterogeneous materials and playfulness through imagination, exaggeration through extension of length and volume, and retro characteristics through reinterpretation of tradition. This study is expected to contribute to creative ideas of modern bag design which requires a global sense, which has been used in various cultures for a long time.

As the development of autonomous vehicles becomes realistic, many automobile manufacturers and components producers aim to develop 'completely autonomous driving'. ADAS (Advanced Driver Assistance Systems) which has been applied in automobile recently, supports the driver in controlling lane maintenance, speed and direction in a single lane based on limited road environment. Although technologies of obstacles avoidance on the obstacle environment have been developed, they concentrates on simple obstacle avoidances, not considering the control of the actual vehicle in the real situation which makes drivers feel unsafe from the sudden change of the wheel and the speed of the vehicle. In order to develop the 'completely autonomous driving' automobile which perceives the surrounding environment by itself and operates, ability of the vehicle should be enhanced in a way human driver does. In this sense, this paper intends to establish a strategy with which autonomous vehicles behave human-friendly based on vehicle dynamics through the reinforcement learning that is based on Q-learning, a type of machine learning. The obstacle avoidance reinforcement learning proceeded in 5 simulations. The reward rule has been set in the experiment so that the car can learn by itself with recurring events, allowing the experiment to have the similar environment to the one when humans drive. Driving Simulator has been used to verify results of the reinforcement learning. The ultimate goal of this study is to enable autonomous vehicles avoid obstacles in a human-friendly way when obstacles appear in their sight, using controlling methods that have previously been learned in various conditions through the reinforcement learning.

Subsidiary welfare facilities in an apartment complex are one of the most important factors for consumers when they buy an apartment due to an increase of consumers' consciousness level, increase of leisure time, and increase of cultural life. This study aims to analyze layout types and characteristics of subsidiary welfare facilities at the apartment complexes in the second phase new towns, investigate the current situation and find out the improvement direction. For this purpose, this author investigated three "second phase new towns" which were designated as a new town at similar time, and selected a total of 15 apartment complexes by selecting 5 complexes in each of the three new towns. Literature survey, case visit, photo shoot, user observation survey were used as study methods. The results of the study are as follows. First, it was found that a mixed type was the most common type of plane layout types in the subsidiary welfare facilities. This type improves accessibility and equity of the residents as the facilities are appropriately placed based on the functions and the user characteristics. Second, it can be considered that a distributed type for senior citizen centers and daycare centers may give independence to specific users, but it may give a sense of alienation to the elderly. Moreover, it does not have enough community so that it is necessary to make proper supplementation. Third, there were two lay out types. The first one is that the subsidiary welfare facilities are placed with step difference and the second one is that they are placed in sunken places using the underground space. Fourth, all layout types of outdoor facilities are distributed types, and it is considered that measurements for a proper balance of accessibility and equity are required.

The purpose of this study is to examine the theoretical background of art make-up and surrealism in depth and shed new light on creative thoughts coming through application of Depaysement and various kinds of expression realized through art make-up, where art and make-up are incorporated. The study method is to conduct prior research followed by a theoretical study of the concept and techniques of Surrealistic Depaysement and theoretical background of art make-up through specialized books and internet sources and then to create 4 artworks representing characteristics of Depaysement technique categorized in dual image, fusion of heterogeneous objects, modification and conversion, and change of space. This examination resulted in first, a foundational ground for fusion and use of art and make-up sectors by creating a realm of expression based on creativity through incorporation of art and makeup and second, a sense of freshness and unfamiliar-ness by creation of an image in a completely unfamiliar space. Therefore, the researcher sets a direction for ways to come up with new ideas and expand the realm of expression and hopes that the art-makeup does not just become an aesthetic tool but turn itself as an art genre.

In the past, design has been recognized as a means to determine colors, shapes, and functions Recently, however, it has been accepted in a wider sense, namely designing the entire service, including product and user experience design. In this way, in addition to creativity and expressive power that designers have as their main competence, according to the expansion of this design object, designers are required to have comprehensive abilities in related fields and accompanying technical professional abilities. If designing as a technology application as a direction toward this situation, design education can be carried out by approaching technology as a method of expression or design subject. It can also be an effective alternative towards improving the understanding of technology. Meanwhile, many small microcontroller board products with advanced functions and multi-functional specialized programming integrated development environments (IDEs) are becoming widespread due to their open source, low cost, and scalable features. However, students in the design department who lack the basic knowledge of science and engineering have difficulties learning, which requires considerable time and is required for practical use. From this point of view, we have made advancements in the technical understanding of design education by conducting fundamental research to the effectiveness of microcontroller-based prototyping tools as means of expression. We also conducted basic education of microcontroller boards for a certain period of time on students who majored in design in conjunction with the basic survey and investigated the obstacle factors using a questionnaire. Through these surveys, we have confirmed the necessity of designing microcontroller boards of low difficulty, which simplify the coding process that can act as a barrier in difficulty for design students to apply smoothly in design education. In addition, we intend to carry out a basic study on the guideline of microcontroller design for design education and composition of education programs.

The driving methods of car are front wheel drive, rear wheel drive and four wheel drive. At driving methods, constant velocity joint is the most important part at carrying out two functions for converting to the direction which the driver wants and transferring the power to wheels. At driving on the road, the impact can be applied to the parts transmitting power according to the state of road surface. In this study, each models of three constant velocity joints whose shaft length are different respectively were modelled with CATIA and the structural and fatigue analyses were carried out by using ANSYS. This study result is thought to be the useful material at designing the constant velocity joint with the durability against impact. And it is possible to be grafted onto the convergence technique at the design of constant velocity joint and show the esthetic sense.

The purpose of this study is to evaluate compatability of seismic source characteristics of the Kern County earthquake to those of Korean Peninsula seismotectonics. The compatability could be used to make Korean type response spectrum from the strong ground motions observed from the assingned earthquake. The July 21, 1952, Kern County, California, earthquake is the largest earthquake to occur in the western U.S. since 1906, and the repeat of this event poses a significant seismic hazard. The Kern County event was a complex thrusting event, with a surface rupture pattern that varied from pure leftlateral strike-slip to pure dip-slip. A time dependent moment tensor inversion was applied to ten observed teleseismic long-period body waves to investigate the source complexity. Since a conventional moment tensor inversion(constant geometry through time) returns a non-double-couple source when the seismic source changes(fault orientation and direction of slip) with time, we are required to use the time dependent moment tensor which allows a first-order mapping of the geometric and temporal complexity. From the moment tensor inversion, a two-point seismic source model with significant overlap for the White Wolf fault, which propagates upward(20 km to 5 km) from SW to NE, fits most of the observed seismic waveforms in the least squares sense. Comparison of P, T and B axes of focal mechanisms and focal depths suggests that seismic source characteristics of the Kern County earthquake is consistant with those of Korean Peninsula Seismotectonics.

The aim of this study is to examine the expression of the meaning of tradition and the archetype of korean image in it in order to find out korean image on reflection of the meaning of tradition. The results are as follows. 1) The nature of tradition illuminates the past, and lights up the present. It cannot be a portrait which enable to have a future prospect and also a cornerstone a tutore pave the way for of the better direction. 2) It's meaning like to say that korean style it self is considered as an expression of tradition. But it korean tradition has a tradition course in a dialectical way, new creation will be possible, 3) The social and cultural aspects change as time goes by through the tendency of society and it's culture we can get some imformation about the inner spirit of human being. The inner spirit of human being is the spirit of our nation so that we can get oringinality from the culture of our nation. 4) On the aspect of idea oganic system must be visualized on the basis of scale whichs accustomed to our emotion. 5) We can also find out the growing tendency that architects are willing to express the typological image as spacial arrangement and ideology of the Korean image to their works recently. It can be defined that it is a progressive tendency for the expression of Korean image in contemporary architecture. This study is needed to have move practical and concrete examination in order to approach more ideologically the expression of the sense of tradition.
