This paper is a study on the anthroposophic characteristics shown in the first Goetheanum. Rudolf Steiner promoted anthroposophy base on the critique of modem times. His philosophy has developed in various areas such as medical science, agriculture, education, and art. In particular, his thinking was well expressed in the first Goetheanum which was built for Anthroposophical Society. The anthrososophic architectural theory is defined here as application of cosmology, metamorphology and geometry. Steiner defined geometry as a unconscious awareness inscribed in skeletal system of human body as humans have evolved in the process of cosmological development. As a result, Steiner's architecture was able to create metamorphological spaces with harmonizing geometric and organic factors. In respect of decoration, the shapes of plants applied to the decoration still kept individuality because of being made manually, thus perfect symmetrical architecture was impossible. Moreover, the first Goetheanum placed an emphasis on formative dynamics. This was to wake an individual's self-conscienceless up, by enabling him to experience with all the senses without reasoning from the precedent.

The purpose of this study is to suggest the interior architecture design studio through the pedagogical method of educational technology for college students who lack self-directed learning. The pedagogical method has been organized to make a student-centered class based on the operation of existing architectural design studios. This teaching and learning method emphasizes the role of teachers as facilitators to help students lacking in self-directed learning in the design process, the BIM visualization to give students an expression of design project and the critics to give students an experience of working circumstances. The results of this study can be summarized as follows. First, This pedagogical model can improve the self-directed learning of students, accomplish the design process well through teamwork, and provide problem based learning (PBL) to settle obstacles that come up during the project. Second, through this model, students can improve their field design capacity by instructor, design feedback and criticism. Finally, This model can suggest new pedagogical methods for interior architectural design studios and management of student-centered studios.

This paper proposes security architecture, security audit framework, and audit check item. These are based on the security requirement that has been researched in the information system audit. The proposed information security architecture is built in a way that it could defend a cyber attack. According to its life cycle, it considers a security service and security control that is required by the information system. It is mapped in a way that it can control the security technology and security environment. As a result, an audit framework of the information system is presented based on the security requirement and security architecture. The standard checkpoints of security audit are of the highest level. It was applied to the system introduction for the next generation of D stock and D life insurance company. Also, it was applied to the human resources information system of K institution and was verified. Before applying to institutions, system developers and administrators were educated about their awareness about security so that they can follow guidelines of a developer security. As a result, the systemic security problems were decreased by more than eighty percent.

Fashion and interior architecture are two areas of design that may share common issues, trends and philosophies, making fashion design human's second skin and interior architecture the third. The concept of 'skin' has become one of the most interesting phenomena in design during the past decade and not surprisingly similar issues can be seen also in fashion and architectural design. The current trend in fashion design is that the skin (clothing) has become detached from the human body and extended into the environment, resulting fashion as art objects. Skin in architecture and interior design has also become detached from the structure so designers have more freedom to experiment by using advanced technologies. The present study attempts to analyze common features of 'skin phenomenon' in fashion and interior architecture that are; detachment, emphasis on space, extension, territorial blending, and digital applications. The researcher has used constant comparative method to categorize the five features among many examples. The limitation of this study is that it is focused on the formative phenomena of projects excluding the philosophies and personal background of each designer. However, it is hoped that the study may assist designers and other researchers to understand relationships between fashion and interior design, hold broader spectrum in art and design.

The two-dimensional (2D) Discrete Cosine Transform (DCT) is used widely in image and video processing systems. The perception of human visualization permits us to design approximate rather than exact DCT. In this paper, we propose a digital implementation of 16-point approximate 2D DCT architecture based on one-dimensional (1D) DCT and Modified Gate Diffusion Input (MGDI) technique. The 8-point 1D Approximate DCT architecture requires only 12 additions for realization in digital VLSI. Additions can be performed using the proposed 8 transistor (8T) MGDI Full Adder which reduces 2 transistors than the existing 10 transistor (10T) MGDI Full Adder. The Approximate MGDI 2D DCT using 8T MGDI Full adders is simulated in Tanner SPICE for $0.18{\mu}m$ CMOS process technology at 100MHZ.The simulation result shows that 13.9% of area and 15.08 % of power is reduced in the 8-point approximate 2D DCT, 10.63 % of area and 15.48% of power is reduced in case of 16-point approximate 2D DCT using 8 Transistor MGDI Full Adder than 10 Transistor MGDI Full Adder. The proposed architecture enhances results in terms of hardware complexity, regularity and modularity with a little compromise in accuracy.

This study will establish the transformal characteristics of architectural visual information by investigating: how contemporary architects perceive and process multifaceted architectural information via the expression media since 1970s. The purposes and results of this study are summarized as follows: This study established the contemporary transformal characteristics by comparing the expression methods of traditional architects with the transformal characteristics of visual information derived from the contemporary architectural expression media. In a pluralistic information society, the expression methods of the past, which recognize space as a stationary, unidimensional visual point on a drawing surface, is now changing to the mixed, multidimensional expression methods that connect various visual points on a limited drawing surface. Furthermore, the rapid advancement of digital media is changing, from a method which simply arranges visual information, to a flexible visual tool which can process architecture sequentially and simultaneously. As the communication structure of architecture is moving toward an individual-centered two-way communication type, the information delivery method is used to visualize conceptual, inferential information, rather than visualizing realistic information which simply records facts. In the past, multidimensional, non-linear forms could not be processed by the conventional design processes and sketch work, but now they can be expressed via digital media.

With developing computer and communication technologies, the concept of CALS system has been popular not only to military but also to commercial industries. The security problem is one of the most critical issues to construct CALS infrastructure. The CALS system needs some security functions such that data confidentiality, integrity, authenticity, availability, and non-repudiation. This paper proposes a security architecture model in CALS. The security architecture model is composed of 5 submodels such that network security model, authentication and key management model, operation and audit model, integrated database security model, and risk analysis model.

In this paper, we have studied temperature compensation architecture for a bust mode optical transmitter to convert the electric burst mode date signal to a optical one through the laser diode. In order to get stable high speed data transmission, we used digital sampling technique with a microprocessor for the temperature compensation of the laser diode, not the previous real time analog technique. Though the digital automatic power control circuit should be complemented the previous analog one with accuracy and effectiveness. So the digital technique will be more effective in further future in development for the over Gb/s transmitting speed.

Fast generation of digital hologram is of importance for real-time holography broadcasting. In this paper, we propose such a method that parallelizes the Computer-Generated Holography (CGH) algorithm for digital hologram generation and make it faster using Multi Graphic Processing Unit (Multi-GPU) with help of the Compute Unified Device Architecture (CUDA) and the Open Multi-Processing (OpenMP). In addition, we propose optimization methods such as fixation variable, vectorization, and loop unrolling for making the CGH algorithm much faster. Experimental results show that our method is about 9,700 times faster than a CPU-based one.
