In a small territory like South Korea, the only alternative to accommodate people in a big city is building apartment house. Exterior traffic noise is not inevitable as the apartment house is set up on wayside or main road is newly established near the area. As the request for quiet environment increases for a better quality of life recently, the exterior noise is considered to be resolved. This study shows the present condition of exterior noise of apartments and reviews a need for the improvement by comparing and analyzing the regulations of main country. Finally, considered the evaluating the interior noise in the apartment house.

The problem of defining the relationship between interior space and exterior envelope of a building has long been a challenging task in the field of architecture throughout its history. This research chronologically reviews some of the important turning points in various schools of thoughts concerning construction of exterior envelope, with focus on how they influenced and altered the formation of our interior environment. This research also stipulates on how technological advance in the late 20th century laid grounds for a new type of interior-exterior relations in architecture through creation of flexible and ambiguous boundary conditions. The focus of this qualitative research will be on contemporary works of Japanese architects Toyo Ito, SANAA, and related group of architects who address the issues of transparency, flexible interior layout, buffer zones, structural facade, and neutralized (homogeneous) space that produces spatial quality of non-linear, non-hierarchical, and de-materialized space as a direct alternative to modern principles of space making.

There passed almost 15 years since our sound quality studies in Japan related to the emitted noise from the industrial products have been started. The sound under consideration are interior and exterior noise from cars, noise from the electric appliances such as electric shavers, electric cleaners and washing machines and the sound emitted from earth moving machines and etc. After a little while since sound quality studies have been started, the products with better sound are gradually on sale on the market.

The vehicle noise is classified into interior and radiated exterior noise. And it influences on consumer‘s vehicle decision and traffic noise environment very much. In case of the vehicle exterior noise, it is related with traffic noise and in case of the interior noise, it is related with driver’s and passenger‘s sensitivity quality. Because these influenced on drivers and traffic environment, so standards are restricted by the laws and regulated for the measurement. But, the existence standards measuring the only sound pressure level are limit to reflect consumer’s sensitive aspects. Therefore in this study, the recent standards and laws were searched about domestic and abroad papers and the testing mode for the sound quality (SQ) evaluation was constructed about the vehicle interior noise. Finally, we aimed at the standard establishment to evaluate the vehicle interior SQ using statistics method.

To begin with the purpose of protecting human life from the exterior in the prehistoric age, architecture was nothing but a shelter without any relation between the exterior and the intoner. But, today, with the community developed, architecture can not be resisted with her own function and have to change of the reciprocal one. Different with the oriental architecture, we can see, western architecture has developed in the stream of the form. The main idea of the space in terms of the relation, above all, is mostly concerned with relation between the exterior and the interior like between the architecture and the city. So the role of the facade in depth is the intermediation which consist to the relation in the exterior and interior of architecture. Considering a relation between two elements; the exterior and the interior, we can be inspired in the case of paintings, especially in the works of the Paul $C\acute{e}zanne$. $C\acute{e}zanne$ originally show the depth of space by different disposition of three parts : the background, the objects and intermediate space between the former. For instance, different with the other painters who put the background rear in the canvas and objects in the front of the background, $C\acute{e}zanne$ took the background and objects a same value and assure a depth in space by virtue of the intermediate space. Finally, by putting the background in forward of layer in the canvas and objects situated behind the background, the depth of the space can be occurred. Same as the idea of $C\acute{e}zanne$, Giuseppe Terragni and jean Nouvelle in architecture also intensify their effects through the activation of intermediate space between the interior facade and exterior frame. Not limited in the relation with the architecture and the city, space in relation gives us a higher quality of architectural promenade in depth.

The exterior system of buildings, which is the typical curtain wall, has been made with glass and metal. Theses materials, however, have weaknesses such as inadequate insulating quality, short durability, combustibility and toxic substance. On the other hand, Autoclaved Aerated Concrete(AAC) or Autoclaved Lightweight Concrete(ALC) possess the great energy efficiency and the superb insulating quality as substitute of existing exterior system materials. In this research, strength characteristics and bubble dispersion of hydrothermal synthesis process of AAC based on CaO/$SiO_2$(C/S) ratio are analyzed. C/S ratio is determinated and bubble distribution and compressive strength are studied through the test of varied water-to-solid mineral ratio(W/S). In hydrothermal synthesis program, final C/S ratio is determined as 0.7 consider of the manufacturing process and hydrothermal synthesis is done at $180^{\circ}C$ for 7 hours. The analysis shows slurry has about 2,300cP viscosity and 0.56 specific gravity therefore it is expected AAC has the appropriate facility in the manufacturing process and Hydrates of AAC's Expansion.

As the modern-day Apartment Complex has varied community facilities such as health care center and self-improvement institutions affecting the residents' quality of life, this paper is for the in-depth understanding on how such Exterior Space vary and development plan should go. To be specific, this paper is to, based upon the theoretical contemplation on the concept and role of the Exterior Space to Apartment Complex, as well as drawing a conclusion on the development plan for subject areas as assessed. Subject areas of this paper are a total of twelve Apartment Complexes built since Year 2005 in nine different regions in Seoul. As such specialties and features as leisure of the senior citizen and female residents, the subject Apartment Complexes have provided opportunities, active and inactive, to the residents for leisure by qualitative improvement of facilities, as well as establishing the discrete brand value for the Exterior Space with featured design and spatial properties. Also notable is the eco-friendliness of the Exterior Space with cutting-edge technology, eventually appreciating the value of Apartment Complex.

When we make a place for people, interior space and exterior space are always connected, each influencing the other. To create a better space or increase the quality of an existing space, it is essential to look at the relationship of inside and outside and their boundaries. Without consideration of the landscape, the building itself gives only limited satisfaction to people. This is an important issue for anyone who deals with space. This study intends to explain the important need for a change in attitude towards our built environment and its intrinsic relationship with its natural context. In the study, I try to find design concepts for integration of inside and outside which have accumulated since early Modernism designers and consider cases with different solutions and approaches that make total design sense when looking at the inside and outside as a whole, then, through observation of the cases, I find 5 design methods(Opening, Continuing, Insulting, Wrapping, Interpreting) in connecting the two spaces and analyze the solutions. The various examples which are shown in each patterns will help us to find ideas for the best solutions of integration of inside and outside. It is true that the idea of integration of inside and outside will increase the quality of our environment and it comes with the current thoughts of ecological and sustainable design. Thereby, I suggest designers to change their manner to continuous and integrated point of view in dealing with built environment.

For lighting design in such diverse structures, we need lots of considerations, such as use and characteristics of the structure, harmony with its surroundings, and the function and type of lighting to be installed. The structural characteristics is determined by its shape and several vertical and horizontal factors based on the shape, which can be focused on at day time by shading, the surface structure, the quality of the surface and the color. On the other hand, they can be at night hidden in the darkness or enforced strongly by the effect of the lighting. In this paper, correlation between the ways of lighting and building facade types according to vocabularies for sensitivity is explored based upon an analysis of building facades for small-scale commerce which plays an important role in cityscape lighting design. It is considered that categorization of types of building facades, presented in this article, and the classification system of exterior lighting methods can be useful in planning lighting. And the process of the study is thought to be able to present a method about the exterior lighting planning. Furthermore, computer simulation on the bases of the correlation model of the lighting methods related to vocabularies for sensitivity about the building facade types is expected to be data and means which can be a great help for designers to predict various results quickly.
