The study on architecture can be started with the aesthetic attitude which cognizes it as the art of the space. Architectural space as the subject of the aesthetical study, however, has been ignored such a long period though it should be centered of the whole architectural theory. Even it has not been dealt with independently but just only as a part of aesthetic or artistic field. Also it is true that academic approach to the architectural space as per the aesthetic cognition has not been done so satisfactorily. This study, therefore, aims at prescribing compositional scope from aesthetic cognition of architecture understanding the rational function, mechanic structure, and artistic beauty by man's subject standard of judgement as per the space, the special sphere of architecture. For the absolves, the architectural space in this study is not approached as the spatial art with the meaning of being included the arts general, but with the meaning of intrinsic peculiarity of architecture, based both in practicality of scientific concept and arts of the aesthetic notiov. In order words, the essence of architecture can be prescribed as the architectural realities as the functional, formal and symbolical space not simply the spatial art, and its real but aesthetic meaning can be cognized aesthetically.

This paper studies the energies and energy release rate (ERR) for the initially rotationally symmetric compressed (or stretched) in the inward (outward) radial direction of the PZT/Elastic/PZT sandwich circular plate with interface penny-shaped cracks. The investigations are made by utilizing the so-called three-dimensional linearized field equations and relations of electro-elasticity for piezoelectric materials. The quantities related to the initial stress state are determined within the scope of the classical linear theory of piezoelectricity. Mathematical formulation of the corresponding problem and determination of the quantities related to the stress-strain state which appear as a result of the action of the uniformly normal additional opening forces acting on the penny-shaped crack's edges are made within the scope of the aforementioned three-dimensional linearized field equations solution which is obtained with the use of the FEM modelling. Numerical results of the energies and ERR and the influence of the problem parameters on these quantities are presented and discussed for the PZT- 5H/Al/PZT-5H, PZT-4/Al/PZT-4, $BaTiO_3/Al/BaTiO_3$ and PZT-5H/StPZT-5H sandwich plates. In particular, it is established that the magnitude of the influence of the piezoelectricity and initial loading on the ERR increases with crack radius length.

An automatic point traffic control method is recommended for more idealistic traffic flow over coarse road netowrks. The automatic control apparatus recommended, consists of a transceiver, amplifier, digital-to-analog converter, signal light controller for emergency and steady state, and digital counter as monitor. The transmitter sends a signal to the target vy means of Microwave-FM-CW and a diode detector picks up the echo signal. Thus the operation of the entire system will be carried out through an open loop state. Some factors necessary for an ideal detector system are rapid response, longevity and stability. An analytical method of the Doppler effect substitutes the conventional frequency deviation into the amplitude of detector output. The changing rate of amplitude is proportional to the voltage of the detector output. Some induced formula from Maxwell's radiation field theory ensures this new method, and, new method, and proves the fact with an experimental data presentation. Stability depends upon Klystron as an oscillator and a diode as a detector. the transceiver installation affects on the response and sensitivity of the system. In accordance with the detector output, several targets are easily classified by amplitudes on the scope. The traffic flow, i.e., target movement which is analyzed by the amplitude method, is shown through the scope and indicates it on the digital counter. The best efficiency for the amplitude analysis can be attained through use of an antenna having the highest sensitivity.

Building information modeling (BIM) can improve to communicate with project participants by early construction involvement (ECI) from the beginning of the project. Therefore, they can minimize design changes and improve design quality and construction. However, because there is insufficient research on the scope and application level of BIM according to project delivery system and project characteristics, construction companies have efficiently not been using the BIM. Therefore, this study intends to conduct basic research as a basis for confirming appropriate BIM application and level according to project delivery system and project characteristics. To do this, we investigated the project delivery system and project characteristics of domestic and foreign projects that have successfully applied BIM, and compare and analyze them based on BIM application and BIM level framework derived from theory reviews and experts. Therefore, this study can be used as a basis for strategically establishing the scope and level of BIM according to project delivery system and project characteristics through the result of this study.

There should be an arbitration agreement between concerned parties in order to resolve a dispute through arbitration. The arbitration procedures, including the selection of the arbitrator and the adjudicative rights of the arbitrator, are based on the arbitration agreement. In other words, the arbitration procedure and adjudication can be carried out within the boundaries of the arbitration agreement. Traditionally, the Doctrine of Separability of the arbitration agreement has been acknowledged in order to emphasize its importance and to clearly separate it from the contract. Today, when the Doctrine of Separability of the arbitration agreement is well established, overemphasizing this separability could hamper its effectiveness and the autonomy of the parties. Moreover, arbitration agreements in the past were required to be written, clarifying the existence of the agreement and determining the scope of its validity. Further, an arbitration agreement was considered as narrowly as possible. However, since arbitration has become a generalized resolution for disputes, the formal or content requirements should be reconsidered. In terms of validity, the subjective and objective scope should necessarily be extended as a means to resolve disputes related to an arbitration agreement and reduce the resolution cost and duration. Under this perspective, the arbitration theory should now focus on arbitration agreements rather than the place of arbitration. We should break from the nationalistic view, which understands that the arbitration system is a part of the national legal system and that arbitration is allowed solely by permission of the nation. Instead, we should extensively reinterpret the subject of arbitration agreement and its range of effects so that disputes can be resolved between the concerned parties under a single procedure and norm, a necessary step forward. Moreover, in spite of the positive contribution and role of the New York Convention toward the establishment and development of the international arbitration system, there should be an effort to overcome its deterioration. As mentioned in the recommendations regarding the interpretation of the arbitration agreement in the New York Convention in 2006, we should begin by striving to match the Convention as a means of interpretation with the changes of the twenty-first century. Ultimately, we should meet the demands of the new era through amendments to the Convention.

Objectives: The Ministry of Employment and Labor has revised the articles regarding management of the thermal environment in the workplace. Currently, two types of regulations exist together with indoor workplaces as the scope of application. It appears that the time has come to discuss regulations. In this study, we aim to identify the feasibility of and problems with the current system through a comparative legal review of workplace thermal environment management laws from around the world. We suggest directions for improving South Korea's workplace thermal environment management laws. Methods: For the several selected countries, we analyzed the classification and content of obligations stipulated for the thermal environment, the presence or absence of specific measures for thermal environment management, legal status and content, and the scope of application of thermal environment provisions and measures. The investigated content was classified according to Zweigelt-Kotz's legal theory. Results: In some countries, employers' obligations for regulating the thermal environment are broadly divided into two types: results and actions. The scope of application of provisions and measures on the thermal environment was extensive, with most of the selected countries targeting general workplaces. Conclusions: In the case of South Korea, restricting and classifying target workplaces and imposing separate obligations to manage a workplace thermal environment goes against global practices, and stipulating legal orders and separate action obligations in guidelines does not conform to the characteristics of South Korea's legal system, meaning that improvement is needed.

The purpose of this paper is to define the spatial scope and landscape structure of the capital city of Shilla Dynasty. We have tried to analyze the locational characteristics, the location and landscape form of the Yonggang-Dong pond site which was assumed a part of a king's place, and had the important implicitness in delineating the spatial scope of capital city of Shilla Dynasty. The research took the theory of landscape cognition as a tool, and processed with the book review related simultaneously. The results of study are as follows; 1) It has been almost conformed that the Yonggang-Dong Pond Site was a part of the North Palace of Shilla Dynasty, and it took the form of fully enclosed by the forest, such as the names of Imjungsu and Gosungsu, and so on. This fact has leaded to the special landscape form of 'Forest with Palace' that is an similar pattern of Forest with Tumulus, Forest having Well, Forest having Well, Forest having Mountain. Each of them is symbolizing the place of holiness in the Shilla Dynasty. 2) The Yonggang-Dong Pond site and its surrounding forests made them together be the north border of the Capital City of Shilla Dynasty. This fact made it possible to consider the form of landscape of the Najung Forest with Posugjung Pavilion as the same on which was on the southern border of the city. 3) The above mentioned facts lead to clues that the border of the capital city of Shilla Dynasty does mean that it was not the mere functional one, but symbolic one. Thus, this paper suggests that the spatial scope of the capital city of Shilla Dynasty should include not only the area of block system, but also the surrounding natural area of mountains, forests, and so on, including the artificial elements of palace and pavilion. 4) This type of borders with the natural elements show basically the different type and function. We could find out some examples from China's and Japan under the same block systems and in the same era. It should be more identifiable in the form and the meaning of landscape of the capital city of Silla Dynasty in ancient Korea.

Purpose: The new-type rangefinder, which is using the biprism principle, is introduced to develop the range finder which can be easily carried by soldiers, and in order to realize those technologies specifically, we try to develop a scope for military rangefinder by doing optical design which can secure enough space to move the biprism. Methods: After setting up the verious initial condition to realize two kinds of goals, that are the securement of enough space to move the biprism and the easy-exchangeability of two kinds of biprisms, and then the optical system was optimized by using optical design program CodeV in order to minimize the finite ray aberrations. Results: We designed the biprism housing to makes it possible to swap the two kinds of biprisms. It was appeared that the Schmidt prism is suitable as erecting prism which can make sure the space to move the biprism. 16.5 mm was good for the face length of Schmidt prism. The optical system with a Schmidt prism and a biprism was designed, and the finite ray aberrations was minimized. Conclusions: We developed a 5X scope for an optical rangefinder using a biprism and a Schmidt prism with 16.5 mm face length. This scope is valid for the optical system which has the effective field angle of ${\pm}3.6^{\circ}$, and the finite ray aberrations are well controlled within the ${\pm}8.95^{\prime}$.

Stage costumes perform not only the instrumental but also the expressive functions. The major goal of this study is to develop the functional and aesthetic costume designs for musical players considering the characteristics of instruments. players’ postures. The scope of this study is restricted to the musical costumes for female adult soloists playing the wind and string instruments. This study is composed of theory research, empiricalresearch and manufacturing a real costume. First, theory research contains theory of musical costumes and that of pure musical areas. Concept, characteristics and wearing effects are analysed in theory of musical costumes. Second, designs of instruments and playing postures are analysed in the theory of pure musical areas. Proper and improper designs are compared based on the survey asking the favorite designs of 56 wind and string players. Third, I manufacture a stage costume for a harpist. The conclusions of this study are as follows. First, wind and string players think the functionality of costumes more importantly than the esthetic sense. And there are differences in design preferences for different playing postures. Second, string Players basically use arms, fingers and the upper body. Wind players use fingers more than string players and do abdominal breathing. Third, string players think the design of arms and sleeves because of frequent usage of bow and prefer the design without sleeves. On the contrary, wind players think the silhouette importantly because of standing playing posture. Fourth, players don't think that the accessory is not important and want it so long as it doesn't hinder playing. Fifth, shoes plays more important role than costume in case of playing posture with using pedals and moving legs frequently. Lastly, both wind and string players prefer the design with simplicity and comfort most.

This study attempts to reconsider the significance of political economy as a theory of knowledge and/or a method for explaining the convergence of broadcast and telecommunications. It is going to suggest what the domains of political economy should be in the future by both highlighting the characteristics and blind spots of previous studies and drawing some distinctive features of a new media environment. The principals and recent research trends in political economy are reviewed in order to make clear that the historical totality as a meta-framework of political economy needs to be reexamined in the era of convergence. Although the scope of political economy has been limited to criticize the structure of media ownerships, the study emphasizes the importance of media consumer theory. It also discusses the problems of free market theory, distortion of active media audience theory, and limitations and creative tension of audience commodity. Finally, this study stresses the significance of audience-oriented policies in order to make approach to practical sides of media politics.
