People grow up and build up most of their character through living in dwelling space and have relax and refresh at home. Creating healthy dwelling space is being considered very important in architectural planning and design for providing comfortable living environment and improving quality of life. One of the properties of the earth is that the earth has a magnetic field associated with it- the Geomagnetic field. The geomagnetic field is produced by a combination of crustal rocks, external electric current systems that surround the earth that surround the earth and currents induced in the outer layers of the earth by magnetic field variations. Human beings have evolved with the background of magnetic field, they are accustomed to living in its presence. Geopathic stress occurs at geopathic zones where the geomagnetic field is disturbed. Geopathic zones exhibit magnetic charges. Geopathic zones are characterized by variations in geomagnetism, for the geomagnetic field is not uniform but exhibits many highly localized distortions, some random, some fairly regular. These occur in geological faults, caves and underground water channel. Many research papers and experiments of the western countries indicates that the geomagnetic field affects the people and living organism in dwellings. Therefore, it is necessary to investigate the geomagnetic field and people's response in living space. In this study the Health Hazard of geomagneic field in dwelling are studied through literature survey of related science field.

In this modern world of drastic change, folding architecture was an alternative that offered a novel architectural insight. Today, the folding technique is being used above and beyond architecture, spreading to fashion, lighting, medicine, etc. Especially in the interior space design field, the folding technique is in the limelight as an alternative to create an original space for modern society. However, research and experiments into folding mainly remains at philosophical interpretation or architectural examples, and even these were mostly before the 2000s. Therefore, the present study determined it necessary to look deeply into the post-2000s folding technique focusing on interior space. In this paper, 33 cases of indoor space where folding technique appears are derived, and classified them again by use. The folding technique which was the first step of Sophia Vyzoviti's experiment on her book, "Folding Architecture" was extracted and used as the framework. We summarizes the range of application of folding techniques (interior space in general, floor, wall, ceiling, etc.) and major folding techniques by combining photographs, drawings, and descriptions of the works of the architects. This paper summarizes the characteristics of the space described comprehensively, and draws out the spatial characteristics of the modern interior space where the folding technique appears.

In this research, considering the practical conditions at field, thermal cracking reducing method was suggested based on the comparative analysis between predicted value and actual value obtained from the actual structure member with optimum mix design. The optimum mix design was deduced from the various mix designs with various proportions of cementitious binder for upper and lower placement lifts of mat-foundation mass concrete. Therefore, before field applications, the mix designs were obtained from the theoretical analysis obtained by MIDAS GEN for upper lift was OPC to FA of 85 to 15, and for lower lift was OPC to FA to BS of 50 : 20 : 30. Based on this mix design, the actual concrete for field was determined and all concrete properties were reached within the predicted range. Especially, the temperature properties of mass concrete at core was approximately $39^{\circ}C$ of temperature difference for low-heat mix design, while approximately $54^{\circ}C$ was shown for normal mix design currently used. Additionally, in the case of cracking index, the low heat mix design showed about 1.4 of relatively high value while the normal mix design showed 1.0. Therefore, it can be stated that applying low heat mix design and different heating technique between upper and lower placement lifts for mass concrete are efficient to control the thermal cracking.

The subject on presentation technique is the class which helps to develop the capability of sensual and creative acts to the students who major in interior design. It helps to understand plasticity and space through the theory of the light and the object, and to develop the capability which realizes one's idea to the actual and visual formations. It also enable the students to explain their designs to the customers by studying the technique which transfers 2D diagram to 3D presentation. Because of these objectives of the class, the departments which major in interior design in Korea consider the class on presentation technique as one of the mun subjects in basic curriculum. However, most of the textbooks related to the presentation technique published in Korea are in the lack of original characteristics for the field of domestic interior design since they refer to or employ the contents of architectural field by directly translating foreign articles. In addition, most of the classes on the presentation technique are taught not by professors but by lecturers so that the class objectives may be varied by their standards for the class. Therefore, it is not easy for each department to set up the one's own characteristics in the field of presentation technique. This study is to analyze the problems in the subjects of presentation technique by investigating the current situations for the subjects on presentation technique in domestic colleges and by surveying the personnels engaged in the field of domestic interior design. Also, the study has the objective to propose the development plan of educational program for the presentation technique in order to enable the student to effectively work in real business.

The sublime as one of categories of aesthetics has given a great influence over art. Particularly, painters of Color-field Abstract, which can be considered as the art of the sublime, have tried to sublimate their art to the level of spirituality through expression of sublimity. The purpose of this study is to grasp distinctive peculiarities of sublimity expressed by Rothko, a Color-field painter, in his architectural work, Rothko Chapel, and manifested by Feldman through his musical piece, also titled Rothko Chapel, respectively.In conclusion, it is found that sublimity was expressed in both works through ‘immobile procession’ corresponding to ‘dualism’ of the sublime as Kant defined. More specifically, it is clarified that such immobility was expressed through the attributes of the sublime as suggested by Burke, and they implied dualism.

Piezoelectricity is defined as the ability of certain materials to produce electric signals when mechanically stressed or to deform when an electrical potential is applied. Piezo technology is becoming increasingly crucial as intelligent devices use vibration sensors to detect vibrations in consumer electronics, the automotive industry, architectural design, and other applications. A wide range of applications is now possible with piezoelectric sensors, such as skin-attachable devices that monitor health and detect diseases. In this article, copper nanoparticles are used in the piezoelectric sensor as the driving agent of the magnetic field. Magnetic nanocatalysts containing copper nanoparticles are used due to their cheapness and availability. Considering that the increase of the electric field acting on the piezoelectric increases the damping (As a result, damping materials reduce radiation noise and increase material transfer losses by altering the natural vibration frequency of the vibrating surface). Among the advantages of this method are depreciating a significant amount of input energy using high energy absorption capacity and controlling slight vibrations in the sensors.

This study aims to analyze the typological characteristics of Alvar Aalto's library design. The unique characteristics of Aalto's architecture are the result of accommodating Modern architecture with regional qualities of Finland. Besides this, Aalto's typological approach in design made his color. The library might be the best example for understanding his design approach in that he showed 3 main features of type; wholeness, self-control and transformation. He established architectural types in his 30s through Viipuri public library and developed so-called fan type library plan. Aalto's library type is not a simple copy of exterior and interior form. It acts as a principle of configuration of his library architecture and applied to the building. Therefore, Aalto's library architecture can be recognized as the results of typological design approach in that it shows the transformation of type in according to factors including site, size, region and cultural tradition. In conclusion, Aalto's libraries reveal the typological characteristics in the field of building layout, dynamic space and the effective use of light.

This research is aimed at being a cornerstone to elicit the evaluation methodology of systematic and objective lighting design process on the basis of investigation of documentation and interviews on lighting design of architecture which is drawing more and more attention in an architectural field. In evaluating lighting design in architecture, such factors as appropriate illumination, quality of light, completion degree, reflection of use, visual amenity, understanding, amiability, artistic value, recognition, regional conditions, and extent of glare are to be more considered than anything else. In so far as general sectors of society show ever-increasing interest in lighting design, developments in both its quality and its quantity are also expected; thus, evaluation items shown in this research will be useful in appraisal of interior and exterior lighting of architecture.
