The following paper deals with the interaction between an Austrian art trend from the late 19th century until World War I, the Vienna Separatist Movement, and the Vienna Workshop dress and its ornaments in part designed by the artists belonging to the former mentioned school. Gustav Klimt′s paintings along with his photographs and pictures and articles published in the "Wiener Mode" magazine were subject of analysis. The focus was on Klimt′s paintings with female themes whereby a comparative analysis was made between the development of the forms, hues and ornaments of clothing and the style of paintings at that time. The whole development was classified into three phases. The first period from 1897∼1905 marks the birth of the Vienna Separatists along with the clothing reform movement. The heyday of the Separatists represents the second phase from 1906∼1913 and the decline of the very school and the Vienna Workshop period lasts from 1913∼1918. Refromed dresses were started to be recognized as alternatives, from 1897 when the Separatists started to gain foot until 1o05, and Kimt and Van de Velde published designs that were comfortable and elegant. From 1906 to 1913 the expressionism and Reform Mode of the Vienna artists started to flourish. But during the War the Separatist Movement, which triggered the modernazation of Vienna declined and instead the decorative art of Vienna Workshops started to develop. The asymmetric design of the dress, exotic patterns, shades of complementary colors and reformed clothing were frequently used by Kimt and other Separatists. This is an instance where fashion design directly influenced art and different branches can reflect the same aesthetic standards within the same time frame.

The cafeteria is one of the welfare facilities in the college and crowed with students during lunchtime because of the various menu, saying time and cheap price. In designing the cafeteria, we have to consider the users' needs and the factors which effect on their satisfaction and behavior under the pleasant environment. The purpose of this study is to draw the environmental improvement factors by Post Occupancy Evaluation. A survey about the users' actual condition and environmental satisfaction level and a behavior observation in the field were utilized as the study methode. The 150 copies of questionnaire were completed by students who ate at the cafeteria of W college in Daejeon city. The SPSS 15.0 for Windows was used for a statistical analysis. The results are listed below; two factors were drawn as the improvement elements through the combination of the unsatisfactory items obtained by the descriptive statistics and the influential items by the multi-regression analysis. They are images and approach. In the 'image' category, there us a statistical difference between the present image and prefer image. The users prefer much brighter, warmer, newer, more gorgeous, more cheerful, more clear, more active, more comfortable, and more modern image of cafeteria. In the 'approach', the location of ail existing cafeteria is inaccessible from the classrooms in spite of an important relationship between classrooms and cafeteria. Therefore the complementary plan for convenient approach is demanded for improvement of users' satisfaction.

This article examined the applicability of spatial configuration to Escher's works through configurative logics and rules and studied the contrasting relations among the unit elements in Escher's works and their characteristics and the creative process of the characteristics. As the results of the study on the bases to maintain and create the partial elements revealed as the characteristics, it was shown that Escher's sequential transformative works demonstrated diverse expressive characteristics as a creative process of Inter-complementary contrasting relations based on the independence of the unit elements. It was also shown that the creative process of the unit elements was actualized through the maintenance base of the fixed and absolute characteristic as the logic for the creation and the creation base of the dynamic and relative characteristic. Therefore, it was interpreted that by applying the logics for creation to Escher's unit elements through the spatial interpretation of the maintenance base and the creation base as well as by configuring the units created in such a way according to the characteristics of Escher's works, spatial possibility canbe derived out from Escher's contrasting tessellation works. The process of spatial configuration is the process to make a balance between various conditions, artists own understanding of the space and his/her intention of the space. From this viewpoint, the logics for maintenance base and for creation base seem to have the potentiality as a spatial configuration to consistently meet the given conditions as well as to derive out novelty through the transformation to maintain the fixed and absolute condition(base) and the characteristics of the independent(additional) transformation arising together with the implicit relations among the transformative units.

Surface has been an important issue in contemporary architecture. That originates in structural freedom of surface since the end of modern architecture and the current stream of surface becoming an identity of building. Development of digital-media has brought a great change to our society in general. Digital-media is characterized by use of digital-information and interactive communication. Digital-media has been applied on surface in contemporary architecture lately. It is a purpose of the study to analyze the characteristics of digital-media application on surface based on the related characteristics of installation art. The categories and the contents for the frame of case analysis were arranged through document research. The foreign and domestic cases of digital-media application were analyzed based on the frame of analysis. Digital-media, which is installed on surface, is interacted with human and surroundings. It enhances emotional communication between human and architecture. Surface is not any more a simple fixture but an interactive creature. It makes surface more dynamically and fluidly that the course of light and human movement affect on digital-media. Surface itself is also turned into an object of art. It reflects the interweaving characteristics between contemporary architecture and installation art. It was analyzed through the study that emotional level of people is the important issue shared in digital-media application on surface and installation art. The complementary relationship between surface of contemporary architecture and installation art can be manipulated by the application of digital-media on surface.

The purpose of this study was to Investigate men's clothing in regard to (1) the effect of wearer's age and clothing: rues on impression formation, and (2) the effect of perceiver's age on impressions formed by the wearer's age and the fuction of clothing cues. The experimental design of this study was between-subjects 24_full factorial design by 4 independent variables. The subjects consisted of 192 subjects in each of two male perceiver groups according to age(20s and 50s). The experimental moterials developed for the study were a set of stimuli al)d a response scale. The stimuli consisted of 16 color photographs made by identical manipulations of 4 independent variables consisting of 2 levels each. Each one of the sixteen sub-samples included 12 subjects from 2 perceiver groups. The independent variables provided by the photographs were (1) wearer's age (20s and 50s), (2) suit color (navy blue and beige),' (3) suit style (single breasted and double breasted), and (4) necktie color (analogous and complementary colors) . The 7-point semantic differential response scale which was designed to measure the impression of the stimuli was composed of 30 bipolar adjectives. The responses to the semantic differential scales were analyzed using factor analysis and ANOVA. The results were as follows:1) Wearer's age, suit color, suit style, and necktie color had significant effects on impression of the 3 factors (appearance·potency, individuality activity, and evaluation) partiafly. However, the suit style was the most dominent clothing cue : the single breasted suit conveyed positive impression of individuality' activity to both of the wearer's age groups than double breasted suit did on both of the perceiver's age groups. 2) Perceiver's age partially influenced impressions formed by the age and the clothing cues of men clothed in suits : the young perceiver's group was less affected by them than middle aged group.

PID control has been well used for several decades. For PID algorithms, some tuning methods are used for selecting PID parameters and with these selected parameters, PID control system is designed. But in some cases various kinds of performance indices are used instead of well-known tuning rules, and so variable type of performance index must be tested so that the designed control system meets the some specifications. For 2 DOF PID controller design this paper presents a linear combinational type of performance indices constituting of index for robust performance, which is obtained by h infinity norm of a weighted complementary sensitivity function, including other time domain indices such as error, energy and changing rate of control input. By numerical methods, the optimal 2 DOF PID parameters are obtained. Therefore various types of 2 degree of freedom PID controllers such as I-PD controller are used so that this two degree of freedom PID controllers may give more desirable output characteristics. Simulations are done with MATLAB m file and mdl files.

In MPEG-2 video standard, there are many parameters to support profiles and levels. It is necessary to verify that a decoder is compliant with the MPEG-2 standard. This paper proposes a design principle of the test bitstreams which confirms that an MPEG video decoder is correct by observing the final image of the decoder under test. The presented test bitstream is composed of two parts. The first part generates a test pattern by varying a selected test parameter. And the following predictive coded picture generates a complementary pattern to the previous image by motion compensation and DCT coefficients. Then it will result in a uniform pattern. We present several bitstreams following the proposed principle. Also we analyze and compare the characteristics of the test bitstreams presented in the MPEG conformance test and the proposed test bistreams.

An Off grid or remote solar electric systems are an energy supply to our home or to our companies without the utility of Grid at all. Off grid solar systems are very important for those who live in remote locations especially for developing countries where getting the electric grid is extremely expensive, inconvenient or for those who doesn't need to pay a monthly bill with the electric bill in general. The main critical components of any solar power system or renewable energy harvesting systems are the energy storage systems and its charge controller system. Energy storage systems are the essential integral part of a solar energy harvesting system and in general for all renewable energy harvesting systems. To provide an optimal solution of both high power density and high energy density at the same time we have to use hybrid energy storage systems (HESS), that combine two or more energy storage technologies with complementary characteristics. In this present work, design and simulation we use two storage systems supercapacitor for high power density and lithium based battery for high energy density. Here the system incorporates fast-response supercapacitors to provide power to manage solar smoothing and uses a battery for load shifting. On this paper discuss that the total energy throughout of the battery is much reduced and the typical thermal stresses caused by high discharge rate responses are mitigated by integrating supercapacitors with the battery storage system. In addition of the above discussion the off grid solar electric energy harvesting presented in this research paper includes battery and supercapacitor management system, MPPT (maximum power point tracking) system and back/boost convertors. On this present work the entire model of off grid electric energy harvesting system and all other functional blocks of that system is implemented in MATLAB Simulink.

To realize a ubiquitous logistics management system using the smart object of Electronic Product Code(EPC) enabled RFID tag, the design and management of RFID Information Service is very important. RFID Information Service searches, transfers and responds to the other's PML request, but Physical Markup Language (PML) data management between trading system elements has issues of standardization of PML data description and processing, and problems of data traffic and communication time overload because of the innate distributed characteristics. As a complementary study, this research analyzes the usage patterns and data types of PML. On that analysis we provide a design of the distributed RFID Information Service architecture of PML data management that is using DB middleware. Standalone and Integrated type of RFID IS were proposed.

Diabetes mellitus is reaching epidemic proportions worldwide. The insufficiency of medication to cope with this burden has coincided with a dramatic rise in the prevalence of use of complementary and alternative therapies, especially herbal treatments. This surge in demand presents a challenge to prove the safety and efficacy of these treatments in diabetes. Korean red ginseng (steam treated Panax ginseng C.A. Meyer) is a strong candidate to succeed. It has been shown to possess a multitude of hypoglycemic effects and improve metabolic disturbances related to diabetes in in vitro and animal models. Data in humans is also emerging to support these benefits. Whether these results can be replicated in a rigorous clinical testing program is unclear. We therefore investigated the antidiabetic effects of Korean red ginseng in a series of 2 acute and 1 longterm randomized, double-blinded, placebo-controlled clinical trials. This paper provides the rationale for this program of study, expanding on the problem of diabetes, its management, and the possible role for Korean red ginseng. It then describes the design and expected findings.
