Although Frank Lloyd Wright represents himself as one of the greatest American master architect, the master architects contribution towards the advancement in the modern history of architecture goes beyond just creating landmark buildings. Through out his life, he was the leading architect not only in the area or architectural design but showed his talent in interior architecture, furniture, fabric, lighting fixture, art glasses, tablewares, silver wares as well as in graphic design which should cover all the elements related to the "total design" in architecture. As seen in his architectural design, the "total design" concept also reflects both beauty and logic of the nature and strengthens his theory of the organic architecture design. The research began with finding out the relationship between his architecture, nature and the supporting design elements mentioned above. the purpose of the research is to analyze the relationship of the spatial organization and the design elements in Frank Lloyd Wrights architectural works from the point of "total design" view and provide the valuable guide line for the development of the modern interior design. His design theory, based on the fundamental ideas of the nature, his organic architecture design, and reference materials to support total design concept will be discussed on chapter 2. And on chapter 3, application of the total design in his actual project will be analyzed. The data and analyzation have been completed based on written references and actual visit to the project sites. Frank Lloyd Wright placed highest value on the human beings and enjoyed presenting new ideas and forms to create better environment for the humans through his architecture and interior design projects. While he was presenting new ideas he continued to support design for democracy which has close relationship to the new frontier spirit of America. He was the master architect for the general society with accurate understanding of the life style of the public with design sensitivity shown in his concept of the total design.s concept of the total design.

In typical master/slave teleoperation systems, a human operator generally manipulates the master to control the slave through the visual information like camera image. However, the operator may get into trouble due to the limited visual information depending on the camera positions and the delay on the visual information because of low communication bandwidth. To cope with this inherit problem in the camera-based teleoperation system, this paper presents a teleoperation system using a reconstructed graphic model instead of the camera image. The proposed teleoperation system consists of a robot control module, a master module using a force-reflective joystick, and a graphic user interface (GUI) module. The graphic user interface module provides the operator with a 3D model reconstructed using a small set of sensing data received from the remote site. The proposed teleoperation system is evaluated through a peg-in-hole assembly task.

RS-485, communication bases from small network system must prepare in collision. The collision is that mean the data transfer breaks. For a stabilized communication chooses 1:N polling methods. But polling is low speed in addition to maybe overload Master device. So, usual N:N Prefers a communication. In this case, must be preparing to avoid collision or some solutions. Generally, to after collision retransmits after short time. It's called delay time for short time. When making a delay time, uses address of each systems. (Address of each node) If the many nodes collided, the each node has different delay time. When making a delay time, uses a usual random number. Making a random number is hard job. So uses a usual pseudorandom number. It is more difficult from small size MCU. The Chaos random number provides stabled value. Finally, when uses the Chaos random number, the stability and reliability of system get better.

Purpose: The aim of study was to compare the dimensional stability of digitized dental stone replica using different color of gypsum materials using a white light scanner with three-dimensional software. Methods: A master model(500B-1, Nissin dental product, Japan) with the prepared lower full arch tooth was used. Several type IV stones(white, yellow, green) were used for 30 stone casts(10 casts each) duplicated a master model of mandible. The master model and the replicas were digitized with the non-contacting white light scanner to create 3-dimensional digital models. The linear distance between the reference points were measured and analyzed on the Delcam Copycad$^{(R)}$(Delcam plc, UK) 3D graphic software. One-way analysis of variance(ANOVA) combined with a Tukey multiple-range test were used to analysis the data(${\alpha}$=0.05). Results: There were considerable differences in mean values between gypsum materials within each color(white, yellow, green), and this difference was statistically significant, p=0.001. Conclusion: Digitization of dental materials on optical scanner was affected by color. Three different color of gypsum materials showed clinically acceptable accuracies of full arch digital model produced by them. Besides, these results will have to be confirmed in further clinical studies.

In this paper 10Mbps master-slave based PLC modems are tested for measuring and analyzing both network and application level performances in the general buildings. The devices under test consist of one master PLC modem and three slave modems. The selected parameters for inspecting the performances are throughput, latency and frame loss rate from the RFC 2544, and one-to-many and many-to-one throughput from the RFC 2285. The results of the performance test show that the PLC modems have Performed better in data transmission when the frame size is increased and the transmission speed is decreased. It is expected that these results will be useful to analyze the effect of noise sources when compared to the performance test under the noiseless environments.

When a Kigong master concentrates the Qi at Yintang, Laogong(P8), Qihai(CV6) meridian points during Kigong state, the change of magnetic field around acupoints Yintang, Laogong points has been measured using DROS-SQUID apparatus. After smoothing process of the continuously measured magnetic signal around acupoints for a few minutes, we could observe that a series of peaks, magnitude of 1～2 pT and period of 5 sec, appeared and find that these peaks were clearly changed as if switch on and off according to Qi concentration state. Before Qi radiation, a series of the peaks measured on Yintang or Laogong point of a Kigong master shows one of either SW-ON state or SW-OFF state as initial state. During Qi radiation, its state becomes inverse of initial state. After Qi radiation, it returns to the initial state for some cases (called P type ; push button switch type) or it remains inversion state for other cases (called T type; toggle switch type). From the data of peaks measured at different position from the Qi concentration acupoint, we found that the Qi radiation on an acupoint makes the switching effect even not at the acupoint that Qi is concentrated but at the other acupoints that Qi is not concentrated.

In this paper, we implemented a high-performence memory controller which can accommodate processing blocks(multiple masters) in SoC for video signal processing. The memory controller is arbitrated by the internal arbiter which receives request signals from masters and sends grant and data signals to masters. The designed memory controller consists of Master Selector, Mster Arbiter, Memory Signal Generator, Command Decoder, and memory Signal Generator. It was designed using VHDL, and verified using the memory model of SAMSING Inc. For FPGA synthesis and verification, Quartus II of ATERA Inc. was used. The target device is Cyclone II. For simulation, ModelSim of Cadence Inc was used. Since the designed H/W can be stably operated in 174.28MHz, it satisfies the specification of SDRAM technology.

This study was carried out to describe and analyze experimental studies conducted in graduates nursing degree. Of 170 experimental studies conducted during the past three decades between 1962 and August 1991, 150 studies were available, including 124 master’s and 26 doctoral theses. This study examined their general characteristics and detailed research methods using percentiles. The results were as follows 1. Most of the studies adopted a quasi-experimental design. 2. The subjects of the studies were chosen by convenience sampling except for two studies whose subjects were drawn by randomization. Studies comparing experimental and control groups were in the highest proportion and the most frequent sample sizes of each group were 21 to 30 for both experimental and control groups. 3. As to measurement, physiological measures were most frequent followed by psychsociological measures and active report questionnaires. Each study, on average, adopted two kind of measurement tools. Studies in which the data collection period was of 1~2 months were in the highest pro-portion. 4. All doctoral theses and 67.0% of master’s theses examined specific research hypotheses. Of these studies, the results of 92.5% supported the hypotheses. 5. Parametric statistics were the major analytical methods. In particular, t-test was used most frequently followed by Chi square, F-test, and Pearson Correlation Coefficients. 6. Patients were the most frequent study subjects. Frequent nursing interventions were information and education followed by support, distraction, and nursing treatments. 7. With regards to the dependent variables, “feelings” such as anxiety, pain, and depression were most frequent. In addition “exchanging” such as restoring, metabolism, cardiopulmonary function, infection and vital signs were adopted as the dependent variables in 29.1％ of the studies examined, while 12.3% of the studies selected “choosing” such as stress, health behavior, or role performance.

It is essential in commercial reactors that the safety limits imposed on the fuel pellets and fuel clad barriers, such as the linear power density (LPD) and the departure from nucleate boiling ratio (DNBR), are not violated during reactor operations. In order to accurately monitor the safety limits of current reactor states, a detailed three-dimensional (3D) core power distribution should be estimated from the in-core detector signals. In this paper, we propose a calculation methodology for detailed 3D core power distribution, using in-core detector signals and core monitoring constants such as the 3D Coupling Coefficients (3DCC), node power fraction, and pin-to-node factors. Also, the calculation method for several core safety parameters is introduced. The core monitoring constants for the real core state are promptly provided by the core design code and on-line MASTER (Multi-purpose Analyzer for Static and Transient Effects of Reactors), coupled with the core monitoring program. through the plant computer, core state variables, which include reactor thermal power, control rod bank position, boron concentration, inlet moderator temperature, and flow rate, are supplied as input data for MASTER. MASTER performs the core calculation based on the neutron balance equation and generates several core monitoring constants corresponding to the real core state in addition to the expected core power distribution. The accuracy of the developed method is verified through a comparison with the current CECOR method. Because in all the verification calculation cases the proposed method shows a more conservative value than the best estimated value and a less conservative one than the current CECOR and COLSS methods, it is also confirmed that this method secures a greater operating margin through the simulation of the YGN-3 Cycle-1 core from the viewpoint of the power peaking factor for the LPD and the pseudo hot pin axial power distribution for the DNBR calculation.

Environmental conservation planning as set forth in the "Framework Act for Environmental Policy" is a representative planning that demands linkages with spatial development planning like urban master plan. However, despite the intentions and efforts of government (including revision of relevant guidelines etc.), controversy still continues regarding the efficacy of environmental conservation planning in respect of its linkages to spatial development planning. Accordingly, this study was devised to examine existing issues and produce proposals for improvement in ensuring the efficacy of environmental conservation planning by local governments. This study focused in particular on the establishment of spatial environmental plans as suggested in the guidelines of the Ministry of Environment for the purposes of strengthening the efficacy of environmental conservation planning. Based of questionnaires for relevant officials of local governments, the study found that although local governments with established current spatial environmental plans are not numerous, the need for establishment of spatial environmental plans were high in terms of the applicability of environmental conservation and spatial plans. Furthermore, this study also confirmed through analysis of questionnaires data, archival research and case study research that there were a number of salient issues including an overly access and program centered planning method based on individual pollution sources and individual post factor measures in the planning aspect, a lack of usable spatial information in the application of spatial environmental information, and inadequate connections with spatial development planning in respect of linkages with other plans. Under these circumstances, various proposals for improvement were presented including the establishment of contents in environmental conservation planning for each urban master planning item from the standpoint of planning, strengthening of basic environmental surveys for spatial planning and preparation of applicable proposals from the perspective of leveraging of spatial environmental information, and systematic improvements that can enable mutual consideration through feedback between environmental conservation planning and urban master planning from the perspective of connections with spatial planning.
