The purpose of this study is to get a more fundamental definition of the term Architecture and Geonchuk through analyzing the origin and reception of the terminus technicus Architektonike. In Latin world the greek term Architektonike was adopted and replaced the term Constructio by Vitruvius and has played a significant role in the history of architecture. In the late 19th Century however, the word Architecture was translated into Geonchuk(建築) and has been dominantly used in countries such as Korea, Japan, and China. But the difference of the denotation between them has not yet been fully evaluated. The term Geonchuk signifies much the same as the Tektonik and remains as such in the architectural discourse. In this context, this study goes back to refer to the philosophy of Metaphysics by Aristotle. In his book the term Architektonike was defined for the first time as terminus technicus, and the philosophies in later Ages of Leibniz or of Kant adopted it to signify the world view in accordance with the time. However, the original thought of the Architektonike disappeared in architectural practice and has been used in most cases as a substitute for Oikodomike which denotes house-building. The usage of this word in later time shows that it lost its foundation to be interpreted not only in terms of principium cognoscendi, but also in terms of principium reale. From this the literal usage of the term architecture and Geonchuk has seldom to do with its original meaning and denotation of Architektonike and also they lost the status of terminus technicus for the discourse of arche which encompasses the meaning of both principle and universal order.

As cyber threats using malicious code continue to increase, many security and vaccine companies are putting a lot of effort into analysis and detection of malicious codes. However, obfuscation techniques that make software analysis more difficult are applied to malicious codes, making it difficult to respond quickly to malicious codes. In particular, commercial obfuscation tools can quickly and easily generate new variants of malicious codes so that malicious code analysts can not respond to them. In order for analysts to quickly analyze the actual malicious behavior of the new variants, reverse obfuscation(=de-obfuscation) is needed to disable obfuscation. In this paper, general analysis methodology is proposed to de-obfuscate the software used by a commercial obfuscation tool, Themida. First, We describe operation principle of Themida by analyzing obfuscated executable file using Themida. Next, We extract original code and data information of executable from obfuscated executable using Pintool, DBI(Dynamic Binary Instrumentation) framework, and explain the implementation results of automated analysis tool which can deobfuscate to original executable using the extracted original code and data information. Finally, We evaluate the performance of our automated analysis tool by comparing the original executable with the de-obfuscated executable.

Stages, in the theatrical spaces, were space, which incorporates aspects of cities. Hence, the stages have been constituted to materialize sequence of city, which has exact number, proportion and order of ideal city. In addition, it has accomplished change, which depends on type of performance with the social condition and culture of generation, city has. However, the original form of theatrical space were forgotten on account of the various changes of theatrical form with modem movement since the end of 19th century, and theatrical space, which does not relate with its space of city, was started to constitute. Particularly in contemporary society, the theatre can give vitality to the citizens, and also theatrical architecture as a commercial code has been a general form, though it takes important role, which improves cultural value with technical improvement of cities development of society. Thus, this study analyzed urbanity ,which theatres have incorporated historically, and deduced a correlativity from to be based on constitution of space in visual, perceptual, spatial constitution and functional role. Focused on published SPAC international competition, it was interpreted by contemporary focus, therefore, this experiment suggests constitution of theatrical spaces of information, takes urbanity, through to analyze visual, perceptual, spatial constitution and functional role in context of contemporary city.

The issue of how to manage the existing records at an archives is very important from the aspects of principle and practicality in record management since it is deeply related with the system of managing new records. Although there are a few studies on filing and criteria on organizing records, they do not often help in the actual site of record and archives management. Therefore, we need to raise the issues that could develop in actual sites and find the ways or resolving these issues, other than the general criteria proposed. Refiling is a very important task for recovering the original order and needs to be a task that should be done according to the overall system and process of record management at an archives. Furthermore, it is very important to objectify and regulate the contents and methods of the task of refiling through the refiling criteria with the content of criteria being specific. From the arguments presented until now, we could tell that refiling falls in the area of record management at an archive directly related with the department of reproducing records at public organizations. Moreover, the role of archivists relates with the task of refiling is critical. Especially, distinguishing job according to chief object is a critical issue in the status and role of archivists at record and archives institutions. This process is important not only at the level of simple job makeup but also in record management. Archivists should be responsible for preparing refiling criteria, reviewing of problems developed in job process, classifying records for refiling, reviewing and refiling of catalogs and key words, selecting equipment and tools, and establishing various forms.

This study was conducted to clarify the formativeness of Cezanne's painting and it's influence on the Modern Fashion. Recently, fashion was introduced and applied the originality of paintings into the fabric and fashion designing. To go with the current of the times I already discussed about the Modern Fashion under the influence of the color of Impressionism and N대-Impressionism in the previous paper. In this study, Cezanne's painting and it's influence on the Modern fashion was investigated. As one of the original Impressionist, Paul Cez anne had been so adversely affected by the critical attack on his contributions to the 1874 and 1877 exhibitions that he never again showed with the group. That is, he was the first Impressionist to become dissatisfied with the superficial recording of atmospheric effects. When he turned to nature, it was not simply to depict the objects that occupied a given site but rather to consider relationships among those objects. Cezanne attempted to track down the fundamental laws of geometrical prototypes of sphere, prism and corn. Color too, he found, could be employed according to principle, like the tones of a musical scale. Throughout the Modern Fashion, various forms of Bustle style dress and geometrical style dress were reappered under the influence of the Cez anne's painting technique. And the order and the unity of all nature was illuminated on the fashion's pattern.

Historically the relation between the power and archives is inseparable. Archives are the recorded traces of political actions and an intention of power has a considerable effect on the existence of archives. In the democratic society the power serves people on the basis of the archives adopted as an evidence of political actions. Archives play an important role for the balance of power, which is a principle point of democracy. Considering the function and symbolism of archives, its proper and reasonable management is connected directly to the protection of people's rights.

In order to improve the energy efficiency of n-Epidemic routing protocol in opportunistic networks, in which a stable end-to-end forwarding path usually does not exist, a novel adjustment strategy for parameter n is proposed using learning atuomata principle. First, nodes dynamically update the average energy level of current environment while moving around. Second, nodes with lower energy level relative to their neighbors take larger n avoiding energy consumption during message replications and vice versa. Third, nodes will only replicate messages to their neighbors when the number of neighbors reaches or exceeds the threshold n. Thus the number of message transmissions is reduced and energy is conserved accordingly. The simulation results show that, n-Epidemic routing protocol with the proposed adjustment method can efficiently reduce and balance energy consumption. Furthermore, the key metric of delivery ratio is improved compared with the original n-Epidemic routing protocol. Obviously the proposed scheme prolongs the network life time because of the equilibrium of energy consumption among nodes.

This study reviewed the theory of acoustic emission applying generation of acoustic emission in metal cutting and proposed a relationship between fundamental cutting parameters and the root mean square (RMS) voltage of the acoustic emission on the basis of the mechanics of the orthogonal cutting operation. Experimental results are presented for 6063-T5 Auminum and the validity of this relationship is evaluated by a series of tests varying cutting speed, feed rate and rake angle in orthogonal cutting. The original formula derived theoretically has been modified in order to utilize independent of fundamental cutting parameters. RMS voltage of acoustic emission depends on cutting speed and strain rate, but it is not much affected by feed rate. Applying lubricant, the drop of RMS level has been observed.

A fast-transient repetitive control strategy for a three-phase shunt active power filter is presented in this study to improve dynamic performance without sacrificing steady-state accuracy. The proposed approach requires one-sixth of the fundamental period required by conventional repetitive control methods as the repetitive control time delay in the synchronous reference frames. Therefore, the proposed method allows the system to achieve a fast dynamic response, and the program occupies minimal storage space. A proportional-integral regulator is also added to the current control loop to eliminate arbitrary-order harmonics and ensure system stability under severe harmonic distortion conditions. The design process of the corrector in the fast-transient repetitive controller is also presented in detail. The LCL filter resonance problem is avoided by the appropriately designed corrector, which increases the margin of system stability and maintains the original compensation current tracking accuracy. Finally, experimental results are presented to verify the feasibility of the proposed strategy.

In order to obtain desired arc welding performance, we already developed an arc welding robot system that enabled coordinated motions of dual arm robots. In this system one robot arm holds a welding target as a positioning device, and the other robot moves the welding torch. Concerning to such a dual arm robot system, the positioning accuracy of robots is one important problem, since nowadays conventional industrial robots unfortunately don't have enough absolute accuracy in position. In order to cope with this problem, our robot system employed teaching playback method, where absolute error are compensated by the operator's visual feedback. Due to this system, an ideal arc welding considering the posture of the welding target and the directions of the gravity has become possible. Another problem still remains, while we developed an original teaching method of the dual arm robots with coordinated motions. The problem is that manual teaching tasks are still tedious since they need fine movements with intensive attentions. Therefore, we developed a 3-dimensional vision guided robot control method for our welding robot system with coordinated motions. In this paper we show our 3-dimensional vision sensor to guide our arc welding robot system with coordinated motions. A sensing device is compactly designed and is mounted on the tip of the arc welding robot. The sensor detects the 3-dimensional shape of groove on the target work which needs to be weld. And the welding robot is controlled to trace the grooves with accuracy. The principle of the 3-dimensional measurement is depend on the slit-ray projection method. In order to realize a slit-ray projection method, two laser slit-ray projectors and one CCD TV camera are compactly mounted. Tactful image processing enabled 3-dimensional data processing without suffering from disturbance lights. The 3-dimensional information of the target groove is combined with the rough teaching data they are given by the operator in advance. Therefore, the teaching tasks are simplified
