This study deals with 8-cheok(ch"), equivalent to 2.4m as the standard scale of architectural module in Korea. 8ch" of Korean module was a unique dimensions compared to other East-Asian architecture. It is inferred that it spread in Joseon Dynasty by the effects of the law which limited the size of buildings and materials according to social rank. 8ch" module was applied to the Palace architecture and the highest grade mansions rather than common and small houses. The application of 8ch" module changed the process of architectural planning, and bred the essential characteristics of Korean architecture in terms of appearance and techniques. In addition, it developed to gain multiformity of composition by combination of other modules.

Effective climate protection is a most important tasks of our time. The BIPV is one of the most interesting and promisingly possibilities of an active use of solar energy at the building. In this study it was analyzed by the case study the function of the requirement of the BIPV-module as building material and this architectural characteristic according to the kind of the module. Therefore the goal of this study is to get securing the application information of BIPV as windowpane. BIPV modules are manufactured in the form of G/G. In the case of the crystal type the Transparent and the light Transmission is to be adjusted by the spacer attitude of the cell. Although this type could not be optimal for light effect of indoors because of the inequality of shade, the moving shade play makes a dramatic Roomimage by the run of sun. The application of this type would be for canopy, window or roof in the corridor or resounds. With amorphous the type it is to be manufactured simply largely laminar, and thus that will shorten building process. There is a relatively good economy to use and to the window system easily. After the production technology is easy the transparency of the modules to adjust, and the module shows to a high degree constant characteristics of light permeability and transparency. Without mottle of module shade is good the use for the window or roof glazing of office, library, classroom, etc. to adapt. The BIPV modules took generally speaking a function as building material to the daylight use, shading, isolation and also to the sight. That means that BIPV modules have as multifunctional system to sustainable architecture good successes and they are at the same time as Design element for architecture effectively.

From the first application of a thermoelectric module to nowtoday, it has been more than half a century. The application of a thermoelectric module is becoming more and more widely accepted since, people's requirement rely more and more on the efficiency of thermoelectric modules and their reliability become higher and higher. So people pay more and more attention to the thermoelectric module. In Around the world, the more research for into improving the efficiency of thermoelectric modules is focused on the current materials. at present. However, the research of into available materials had has some limitations, and the research of materials had reached a bottleneckthere are limits to current applications. On the other hand, from the production process, if we assembled by materials withoutmodules without any damages and achieve the ideal state of a joint, we can make the a product to maximize performance and have a longer service life. SoTherefore, in this study we will prove the relationship between the any defects inside and the efficiency of a thermoelectric module to improve the quality management and performance of modern thermoelectric modules at present.

A new idea of the wavelength locking module for DWDM application was investigated in the present research. Only one etalon photo-diode is generally used in the internal/external wavelength locking system. For the internal wavelength locking module with 50 GHz applications, an algle tuning method of the etalon commonly applied. However, the alignment process of the etalon with the angle tuning method is limited because the lock performance is extremely sensitive accoriding to the change of the tilting angle. In an optical viewpoint, the alignment tolerance of the locker module with the etalon PD array block was good, and the precise tuning of the wavelength was possible. The characteristics of free spectral range (FSR) and peak shift of wavelength according to the tilting angle with the locker module was investigated. For the present module, the optimized initial tilting angle was experimentally obtained.

The forms made by repeated arrangements of basic units defined as Simulakre are recomposed into organic, geometric or multi-functional forms by diverse combinations and arrangements and the space expanded by reiterated compositions will have the meaning of active space expansions representing speeds, rhythms or time by reiterations instead of a limited and fixed place shown by a work. The module design that can create new roles and functions of spaces that are variability and fluidity and that can be assembled and transformed into the shapes, sizes and functions desired by users will be analyzed applying the concepts of reiteration and expansion. The module designs emerging in 21th century are in diverse organic forms and geometric forms and their methods for expansion are also diversified. And instead of having a function, they have diverse functions such as storages, partitions, walls, curtains and soundproofing. The development of module designs are first to satisfy the diversified needs, individualities and desires to posses of modem people and second the development, finding and application of new materials. In the future spaces that will continuously develop and will be nomadic, the flexible and individualized module designs will become more diversified and will have their significances.

As vehicles become more intelligent for convenience and safety of drivers, the in-vehicle networking(IVN) systems and smart modules are essential components for intelligent vehicles. However, for wider application of smart modules and IVN's, the following two problems should be overcome. Firstly, because it is very difficult that transducer manufacturers developed the smart module that supports all the existing IVN protocols, the smart module must be independent of the type of networking protocols. Secondly, when the smart module needs to be replaced due to its failure, only the transducer should be replaced these without the replacement of the microprocessor and network transceiver. To solve these problems, this paper investigates the feasibility of an IEEE 1451 based smart module. More specifically, a smart module for DC motor control has been developed. The module has been evaluated for its delay caused by the IEEE 1451 architecture. In addition, the time required for transducer replacement has been measured.

Building Integrated PV(BIPV) is one of the best fascinating PV application technologies. To apply PV module in building, various factors should be reflected such as installation position, shading, temperature, and so on. Especially the installation condition should be considered, for the generation performance of PV module is changed or the generation loss is appeared according to installation position, method, and etc. This study investigates variation of electrical characteristics of a PV module according to the change of irradiance and temperature. From this experimental study, we confirmed that the irradiance, the temperature variation and the generation performance of a PV module were appeared differently according seasonal variation. Actually the PV module installed in building facade showed high-generation performance in winter.

Building Integrated PV(BIPV) is one of the best fascinating PV application technologies. To apply PV module in building, various factors should be reflected such as installation position, shading, temperature, and so on. Especially a temperature should be considered, for it affects both electrical efficiency of a PV module and heating/cooling load in a building. This study investigates a semitransparent PV module that is designed as finished material for windows. Therefore it needs to considerate about the optical characteristics of the transparent module. It reports the effect of thermal and optical characteristics of the PV module on generation performance. The study was performed by measuring sun spectrum and luminance through the PV modules and by monitoring the temperature and experiment. The results showed that 1 degree temperature rise reduced about 0.48% of output power.
