This study aims to show the present status of the expressions in the contemporary architecture in Kore under its pluralistic and equivocal situation. Non-residential buildings constructed since 1960 till 1997 have been analyzed focused on the rationality romantic property and koreanity which are the expressional aspects and its expressional characteristics in contermporary architecture in Korea such as the properties of the quasi-thematic approach limitary subsistence unexisting common ownership mixed copy and normative diversity have been grasped. These results prove that the common features after Modernism such as the restoration of humanity search for the architectural forms of plural meaning the pursuit for the regionality are also applied for the expressions of the contemporary architecture in Korea, Also this study can be the attempt to clarity the identity of the contemporary architecture in Korea and where it is now.

This study is concerned with air-conditioning system in use of thermoelectric device. It is introduced that the well designed structures for better cooling & heating performance with high efficiency. And also it is performed that the system performance test of four types trial products for the use of hybrid commercial vehicle. System performance is affected by many component parts, especially heat sink design & power control method. It is applied that dual extrusive fin tube with buffer zone for the effective radiating of circulating liquid in tube. And also it is applied that power supply method with constant-current system. It is attained that system cooling capacity is 1.2kW, COP is 0.95.

In order to design a stable robust controller, nominal model, and the upper bound about the uncertainty which is the error of the model are needed. The problem to estimate the nominal model of controlled system and the upper bound of uncertainty at the same time is called robust identification. When the nominal model of controlled system and the upper bound of uncertainty in relation to robust identification are given, the evaluation of the validity of the model and the upper bound makes it possible to distinguish whether there is a model which explains observation data including disturbance among the model set. This paper suggests a method to identity the uncertainty which removes disturbance and expounds observation data by giving a probable postulation and plural data set to disturbance. It also examines the suggested method through a numerical computation simulation and validates its effectiveness.

Nowadays minimalism has influence on Korean Architecture and Interior Architecture at the turning of new generatiov. Minimalism is a plural phenomenon that has developed from Modernism to Contemporary but there is the tendency to define minimalism within Architecture and Art. Also it is a fact that there are many disordered minimal aspects in Architecture. This study is started from accurate understanding the mistakes in the field of Interior Architecture, that are brought by the elapse of time, and analogizing the circumstances of Interior Architecture in the field of Architecture. Especially the purpose of this study is to grasp the relation between the minimal characteristics of Korean traditional Architecture and the stagnancy of Korean Architecture. Under the assumption that the characteristics of minimalism exist in Korean tradition, this study contents the characteristics of minimalism in western modernism to analyze the contemporary Korean Architecture and interior Architecture that the assumption is appled to.

Various M2M applications have different quality-of-service(QoS) requirements to be implemented practically. QoS requirements are normally data rate and delay constraint. However, there are limited number of wireless communication chip solutions which cannot support QoS requirements for all M2M application. Hence, aggregated usage of plural wireless communication chip solutions should be needed to implement M2M applications. In this paper, we consider the case that two wireless communication chips using random access protocol work together to transmit data of an M2M application. In such case, data rate and delay performance are mathematically analyzed. In our results, practical data rate can be improved from 2.5 to 7 times while delay constraints are satisfied if we simply use two wireless communication chips together.

Streaming server is that an image produced in real time or a file form of image produced ahead consists of SNS service, and the relay module of streaming server includes output management module that set an output channel more than 2 and control transmission of video content. This thesis intends to suggest how to stream through plural output channel that contains output channel of external streaming server using relay module and do streaming provided to terminal receiving image, and streaming server, streaming system for this. Thus, by extending output channel sending out image to output channel of external streaming server, the scale of streaming server is not limited and the process allotting external streaming server into output channel sending the image becomes simple, so management of output channel becomes efficient even when sending several images.

A routing protocol in mobile ad hoc networks is important, and a location based routing has attracted attention. We have proposed a method, in which plural mobile agents (MA) manage location information and construct a route and the number of MA dynamically changes depending on the network situation. However, the area where each MA manages is not always appropriate. This would increase the network load due to unnecessary split and mergence of MAs. To solve this problem, in this paper, we propose an enhanced method. In this method, the MA management area is properly determined based on distribution of nodes. From the performance evaluation, we show that the proposed method outperforms conventional methods in terms of packet delivery rate when network load is high.

The history of statistics from the mid-seventeenth to the early twentieth century is considered and a scheme of periodization is proposed. In the first period(1650-1750), named 'the age of probability' in this paper, concept of probability emerged, and in the second period(1750-1820), named 'the age of error theory', statistical techniques such as the least square method are developed by astronomers and geodesists. Their techniques are supported theoretically by mathematicians like Laplace and Gauss in that period. The third period(1820-1880) is called 'the age of statistics(as a plural noun)' since statistical data played prominent roles in social sciences such as sociology, psychology. Finally the last period(1880- ), called 'the age of statistics(as a singular noun)', the discipline of statistics came to maturity both in theory and application.

In this paper, a predictive fuzzy control algorithm to supervise the elevator system with plural elevator cars is proposed and its performance is evaluated. Elevator group controller must decide the service elevator for a registered hall call to satisfy the multiple control objects. The proposed group control algorithm ensures the efficient operations of the group cars and provides the improved level of service, coping with multiple control objects and uncertainty of system state. The feasibility of the proposed control algorithm is evaluated by simulation on computer.

This study aims to analyse a trend of exoticism which is often mentioned in the contemporary western fashion. I analyse the internal elements of the exoticism in the fashion. By applying these elements to the exoticism of modern fashion, I intended to make it a useful instrument fur interpreting modern fashion. The results of this study are as follows. The internal elements of exoticism are summarized as escapism, curiosity, fantasy, hybridism and pluralism. 1. From the 19th century to the 1960s . The exoticism shown in the western fashion are influenced by such elements as curiosity and escapism. And diverse and plural exotic elements added a fantastic element to the exoticism. 2. After 1960s : Escapism acted much more because people thought exoticism offer a refuge from overall social problems of modern consumer society. Late in the 20th century, fantastic and hybrid element became more prominent in exoticism. And I found pluralistic view point was the other element of exoticism.
