  • Since the high performance analog-to-digital converter can be built with Rapid Single Flux Quantum (RSFQ) logic circuits the development of superconductive analog-to-digital converter has attracted a lot of interests as one of the most prospective area of the application of Josephson Junction technology. One of the main advantages in using Rapid Sng1e Flux Quantum logic in the analog-to-digital converter is the low voltage output from the Josephson junction switching, and hence the high resolution. To design an analog-digital converter, first we have used XIC tool to compose a circuit schematic, and then studied the operational principle of the circuit with WRSPICE tool. Through this process, we obtained the proper circuit diagram of an 1-bit analog-digital converter circuit. The optimized circuit was laid out as a mask drawing. Inductance values of the circuit layout were calculated with L-meter.

  • As the number of people who live indoor space has been increased, the interest in 3D indoor spatial information has been grown. Object-Oriented 3D indoor space modeling including indoor spatial information has performed in level of detail 4, and modeling data is able to be constructed based on various raw data which are as-built drawing, laser scanning, BIM data, and camera. 3D indoor space modeling has been worked based on established indoor space modeling process, and the result can be used for various application fields such as indoor space pedestrian navigation, facility management, disaster management, and so on. However, the modeling process has limitations to perform indoor space modeling efficiently, because the process is complicated and wastes time at modeling work. In this paper, we propose evaluation on practical use of raw data for 3D indoor space modeling purpose on supporting efficient indoor space modeling through analyzing the established process. Therefore, we define the requirements to evaluate the practical use of raw data and propose the verification method. In addition, as-built drawing which has been used in Seoul 3D indoor space modeling project will be applied to proposed method as a raw data.

  • The majority of fishing vessels(under 20 tonnages) in Korea have a high casualty accident of the flood and capsizing occurred by lack of stability. Actually, it is so difficult to make out the data of inclining and stability tests of small fishing vessels after building, because most of them were built on experiences of manufacturer. According to above reasons, the aim of this study is an attempt to propose a stability criteria of small fishing vessels as follows: Firstly, it is examined that the stability is driven from a transverse metacenter height of actual ships, which is able to obtain a basic drawing and stability data. Secondly, it is examined the heeling at high-speed turning, and the period of rolling according to B/D(breadth/depth). Finally, it is suggested the stability criteria by using a dynamic state which is applied in passenger boat and fishing vessels over 24 meters.

  • Generally, there is confusion as to what constitutes TQM, though it can be regarded as a set of concepts and tools for getting all employees focused on continuous improvement, various schools of thought have defined or classified the critical success factors as constructs, concepts and principles. Therefore the main aim of this paper is to provide a practical approach for understanding the quality management terminology. Using the existing quality management measurement instruments available in literature, the terminology used is classified into constructs, practices and finally tools or techniques. Quality Management may then be viewed as a combination of the three sets of terminology. Drawing on the quantitative study which investigated the implementation of TQM within the SME, the critical factors of TQM as used in that study as used to demonstrate the practical approach or methodology for the understanding of the terms thus used. For the benefit of practitioners within the Construction Management field, a bit of clarity is required as regards the terminology used. This study contributes to clarifying the conflicting results being reported in the quality management literature which inevitably leads to having different levels of analysis of Quality Management. Accordingly, the strength of quality management compared with other business philosophies should then focus on the practical methodology, namely the practices and techniques.

  • Gyeonghuigung palace is an important site as it was the secondary palace in Hanyang from the $17^{th}$ century to the mid-$19^{th}$ century. Its original state was lost because a number of buildings were damaged and the palace area was reduced. The entire palace can be seen only in "Seogwoldoan" a drawing of the western palace. With "Seogwoldoan" to show the complete configuration of Gyeonghuigung palace in detail as the main data and other relevant data used as supplementary sources, the aim of this work was to identify the figurative features around the plantings and the space configuration of the royal garden in Gyeonghuigung palace. The space configuration observed in the royal gardens in Gyeonghuigung palace deviated from the norms and strict systems of royal palaces. The free and uninhibited configuration of the royal garden was allowed in Gyeonghuigung palace because it was built as a secondary palace in a lower hierarchy. Furthermore, a royal garden characterized by unique and unlimited planting was created, with several spaces acting as both royal garden and rear garden as the rear gardens could not be separately configured due to the narrow space of Gyeonghuigung palace.

  • The development of diesel power generation is predominantly geared toward island areas or ships because diesel exhibits weak scale-merit characteristics and power quality problems, which are associated with environmental pollution. However, a new energy paradigm, distribution energy resource (DER), has been emerging as a renewable energy source due to the existing structural problems in waste disposal and complex factors such as the conversion technology of waste emulsified oil (WDF). By combining extended producer responsibility (EPR) support and renewable energy certificates (REC), including waste energy REC 0.25 for other bioenergy and REC 1.0 for power transactions, an adequate profit model can be built through self-energetic power generation, thereby drawing keen attention from related industries. Therefore, if WDF is used appropriately as a high-quality engine fuel, it can lead to the development of various fields such as novel renewable energy sectors, waste management, and EPR-related industries. This study is intended to produce WDF using plastic waste by using it as engine-generator fuel. Moreover, we investigate ways to improve the quality and suitability of WDF as an engine fuel.

  • As a type of intimate architecture, fashion has always mediated the dialogue between clothes and the body, or fashion and figure. This study seeks to inquire the current aesthetic consciousness of the body and dress in Japanese avant-garde fashion and intends to research the features and meanings in the pastiche of Western sartorial convention in Japanese avant-garde fashion in order to examine the changing aesthetic attitude in postmodern fashion. The study investigates subjects of the fashion collections of the turn of the twenty-first century, when pastiche strategies frequently appeared in Japanese avant-garde fashion, through the methodology of literature research and case analysis. The results of the study are as follows: by developing the strategy of pastiche, Japanese avant-garde fashion exposes the defectiveness of the Western idea of the idealized and standardized body for mass productions, thus freeing design from its traditional confinement to the human body. Drawing on the re-conceptualization of the sartorial convention of Western tradition, Japanese avant-garde fashion designers tend to experiment with extreme exaggeration in form, refusing to subscribe to the traditional Western values built on the balance and symmetry of the body. Through the combination of the past and the present as well as the inner-wear as outerwear strategy, the historical pastiche challenges convention and symbolism, which results in the discord between signifiant and signifi$\acute{e}$ of clothing.

  • The concept of the modern consumption is not limited to the value of use by mere purchasing and using of the products. The consumers in modern capitalistic society, consumes the semiotic value whose meaning is socially granted, as well as the value for using. Therefore, that tendency that the symbolic sign of the products is consumed to differentiate oneself from the others and express oneself appears. The designed hotel that reflects the features of sign consumption in the modern society and where the discriminate experience can be enjoyed through the unique and diversified design expression is drawing our attention. Therefore, in this paper, based on the theoretical consideration of semiotics, the tendency of sign consumption and its feature appearing in the modem society has been studied. And through the case studies of the hotels which have been built since the 2000s, how such features can be expressed in the space has been studied. As a result of the study, as for the features of expression of modern semiotic consumption society shown in the design hotels, the diversity breaking from the uniformity by the diversified thinking, the hybrid attribute, and the attribute of the differentiated entertaining images, based on hedonism, the inherent symbols and narrative attribute, and the flexible interactions through the experience of emotional consumption, are appearing.
