Recently, due to the child-friendly city project being conducted by UNICEF, the movement to create a child-friendly cities has been actively promoted by the South Korean government. However, due to the lack of specific physical plans to improve the basic rights of children in the city, the project has been mainly implemented for educational and institutional projects. In this study, we investigated the activities of children and parents living in elementary school neighborhoods. Based on our investigation, we attempted to generate the desired results that can be referred to by physical planners looking to make changes to school neighborhoods by comparing and analyzing children and parents' activity range and life patterns in the neighborhood. The GPS and traffic log surveys were conducted as the primary research methods. The results of this study are as follows: First, both children and parents are most likely to walk in their neighborhoods. In addition, the use of private cars and school vehicles was high, but the use of public transportation was low. Second, the longer parents and children stayed together, the wider the range of their activities. Third, children who spent a lot of time with parents were more likely to have diverse life patterns than children who did not spend a lot of time with parents. Fourth, parents who live in elementary school neighborhoods frequently used commercial facilities and cultural centers around the school. Therefore, it is important to construct facilities around the school for parent-use.

During the Joseon Dynasty, the rituals that were celebrated in the palaces were mainly held inside the palace and in the courtyard of the palace. Mats were spread on the floor of the place where the ritual was held. The mats spread in the Joseon Dynasty rituals divided the space in various ways, and in particular, they were spread in a certain form in the spaces of royal wedding, customs, and court banquet. Mats were the primary physical element that divided the royal ritual space of the Joseon Dynasty, and functioned to elevate the general space to the ritual space. In the ritual space, mats were spread inside the palace, and divided the courtyard of the palace into left and right in a symmetrical form to distinguish the hierarchy of the participants. Mats with special and white patterns were spread in the external ceremonial space and mats with flower and colorful patterns were spread in the internal ceremonial space. This was the subdivision of the Confucianism's male-female division through the mat. The pattern of the mat that divided the space of the royal family elders also meant longevity to reflect the filial thoughts of the Confucianism through the mat. Mats were a physical element for subdividing the royal family and the participants in the hierarchy of the space where the ritual is held, and it also performed a subdividing function between the royal participants. In other words, in the Joseon Dynasty ritual space, mats were temporarily spread while the ritual is being celebrated and functioned to elevate the space to a ritual space. It is confirmed that the fact that the mats were temporarily spread to divide the space into the hierarchies according to the status and were subdivided into colors and patterns to perform the function to reflect the subdivision of the royal family according to Confucianism and the statue of filial piety in the ritual.

The premise of this study is that an ultimate objective in planning an exhibition space is visitors' experiences created by a result of their first-hand experiences and responses within an exhibition space, and this result can be recognized in the visitors' movement. Thus, the exhibition layout that can directly affects viewers' main line of flow and movement patterns was examined vis--vis a mutually complementary relation in a triangular composition with the structure of exhibition space and the exhibition contents. This study, with the subjects of standing exhibit halls of Gwacheon National Science Museum, Daejeon National Science Museum, and Tokyo National Museum of Emerging Science and Innovation, analyzed 'the correlation between the configuration of the exhibition area and the visitors' movement. The targeted subjects were analyzed from the perspectives of type of architectural space and organization of the exhibition method, and the purpose of this study was to find a spatial evidence to predict the spectator movement formed within the exhibition halls of science museums. The main indicators used are: Based on the investigation/analysis as described above, the following conclusion could be drawn. Diversity of exhibition environment and spectator movement: besides the two big categories of the types of architectural space and types of exhibition method, the construction of vertical circulation and size and shape of the exhibition space, distribution characteristics of exhibition medium, organization of symbolic space and such other diverse organizations and combinations of exhibition environment are implied to have the capability to alter the scope and degree of predicting spectator movement. As an example, the types of architectural space comprising the wide-area viewing circulation was found to be able to change the system of planar circulation according to the composition of vertical circulation. Along with this, it was implied that the format of architectural space influences the form of the exhibition space, and may also act as a factor directly influencing the diversity and arrangement of the exhibition methods. That is, the spatial elements comprising the exhibition environment acts inter-complexly, and exhibits characteristics of limiting or controlling spectator movement.

A typology study is a comparative study of the physical characteristics of the built environment divided into distinct types such as architecture, culture, and environment. Lao vernacular dwellings were initially created based on the Lao people's behavior in terms of beliefs, traditional culture, lifestyle, and local wisdom with regard to the environment, climate, geography, and materials. The main research method used in this study is a comparative case study of three ethnic dwellings. The multiple data collection tools employed included second source data and primary data to analyze the findings of the unique characteristic typology of Lao vernacular dwellings. The objective of this paper is to compare the cultural and physical contexts, the patterns and origins of settlement, the architecture, the cultures, and the local indigenous knowledge related to the dwellings and settlement of the three main ethnic groups. These three groups are rich in tradition and their documentation is therefore essential for the intellectual history of the society of Lao; this research could therefore aid in enhancing our understanding of the three typologies of Lao vernacular architecture and settlement within the historical and sociocultural contexts of each ethnicity to convey an understanding of Lao vernacular dwellings by analyzing their different types to help identify the differences and similarities among architectural artifacts by recognizing the invisible connections between them, whereby the figurative ornamentation is based on the relationship between man and nature. This study also provides a glimpse of the living culture and characteristic features of Lao vernacular architecture.

In the buildings with long spans and high floors, such as logistics warehouses and semiconductor factories, it is difficult to install supporting posts under beams during construction. Therefore, the size of structural members becomes larger inevitably, resulting in a significant increase in construction costs. Accordingly, a prestressed hybrid wide flange (PHWF) beam with hollowed steel webs was developed, which can reduce construction costs by making multiple openings in the web of the steel member embedded in concrete. However, since multiple openings exist and prestress is introduced only into the bottom flange concrete, it is necessary to identify the shear resistance mechanism of the PHWF beam. This study presents experimental shear tests of PHWF beams with hollowed steel webs. Four PHWF beams with cast-in-place (CIP) concrete were fabricated, with key variables being the width and spacing of the steel webs embedded in the concrete and the presence of shear reinforcing bars, and web-shear tests were conducted. The shear behavior of the PHWF beam, including crack patterns, strain behavior of steel webs, and composite action between the prestressed bottom flange and CIP concrete, were measured and analyzed comprehensively. The test results showed that the steel web resists external shear forces through shear deformation when its width is sufficiently large, but as its width decreased, it exerted its shear contribution through normal deformation in a manner similar to that of shear reinforcing bars. In addition, it was found that stirrups placed on the cross section where the steel web does not exist contribute to improving the shear strength and deformation capacity of the member. Based on the shear behavior of the specimens, a straightforward calculation method was proposed to estimate the web-shear strength of PHWF beams with CIP concrete, and it provided a good estimation of the shear strength of PHWF beams, more accurate than the existing code equations.

Records of architectural cultural properties, in case of accidents, show who are to blame, present what evidences are to establish the cause, and also are used for checking if there were any problem in policies and regulations in preserving and caring architectural cultural properties. These records are of great importance in their roles and are of essential use regardless of time and space. Considering its significance, In that architectural cultural properties requires setting clear goals and directions and as well, criteria, for management, we need methods of systematical control and consideration for its characteristics. This research started with the sense of purpose that managing architectural cultural properties are in need of systematic and concrete control, based on the perception that they need protecting and transmitting. The goal of this thesis is to work on the current archiving status of architectural cultural properties by monitoring patterns and processes in archival administration, to diagnose problems by looking into the records creation and management, and to present the improvement plan which would lead to the architectural cultural properties' more efficient management and better use in the future. The management of architectural cultural properties begins with registering and assigning. Cultural Heritage Administration is in charge of control, supervision, and budget and local governments deal with direct management. Accordingly, records are by the hands of each local governmental body. Currently, each cultural property has its management depending on every different working environment in each governmental body. Architectural cultural properties needs managing in one body through the synthetic and unified, concrete and systematic manual and guide for management. Archiving architectural cultural properties have need of unitive management through a professional system, considering the physical characteristics and history of archiving. Unified management system will enhance efficiency and actual use of architectural cultural property records if one governmental body undertakes uniting records through standardization and professional supervision, and data-based unified search engine would enhance efficiency and actual use. Therefore, I suggest that Archives for Architectural Cultural Properties should be established as a professional Archives and wholly responsible body for the purpose of systematically and unifiedly managing architectural cultural property records with professional personnel and facility and transmitting their historical, cultural, and academic value. In Korea, studies up to the present have mainly focused on managing architectural records and records of drawing while few efforts were made to directly deal with managing architectural cultural properties themselves. The focus of this thesis is to study the current status and establish problems of the management of architectural cultural properties in administrative process, and as a result, to propose to establish Archives for Architectural Cultural Properties as a professional archives.

Conventionally, ornament has developed around linear thinking based on Euclidean geometry, and been explained as simple and lucid natural Euclidean geometrical phenomena. The modular arrangement with vertical, horizontal and diagonal grids has been an organizing principle of classical ornament, but in digital era ornament is found not to be explained only with the principle of traditional arrangement due to the seemingly irregular complex forms. In that sense, this study presents the concept of digital ornament and examined the backgrounds of ornament in digital age, that are complex system and non-Euclidean geometry. Accordingly, the present study takes an approach by dividing new formal types of ornament into algorithmic form, hybrid form and dynamic form to find out a principle of pattern organization. Lately, architects who actively use computer for their architectural designs take the algorithmic strategies in nature and create various and complex patterns by simple rules. The patterns are not the repetition of the same, but the production of singularities. In addition, hybrid form by morphing shows a topologically flexible evolutionary transformation, and is used to create in-between transitional shapes from the source to target. Finally, the patterns by the interaction between the system components which are corresponded to the embedded forces emerge from dynamic simulation of the natural environment. Rather than objects itself, focus is given to the process of generating forms, and the ornamental patterns as the revelation of such implicit order provide not just the formal beauty but also spatial pathways for lights and air, maximizing the effects of lights.

Relationship between body and space is fundamental in space design. The perception and concept of human body in each age directly affected the space makings of that time. Thoughts on human body are related to various periodical backgrounds such as culture, art, technology and etc. Body-Space relationship has been changed through different epochs and is being changed in the present time too. In contemporary cities, architectural programs has been fragmented and activities of individuals become more articulated. The rigidity of each architectural program has been forced to be more flexible amalgamation of diverse behaviors by dynamic urban time-space formations and patterns. Based on this current situations, new experimental designs that question the existing preconceived relationship between body and space in different views. These design experiments attempt to overcome the solid physical fixation of architectural buildings and to directly relate human body to intelligent devices, technologies, machines as well as spaces. This research focus on the innovative design projects in which body, machine, space are smartly compound as one organization. The purpose of this study is to examine the new Body-Space relationship as well as some relevant case projects in contemporary fashion, furniture, interior design and architecture.

The objective of this study is to define the plans of eco-friendly housing and the meaning of architectural imagination, and to classify diverse sources of the origins of architect's imagination to propose a desirable green housing plan. Generally, imagination which means the process of forming in the mind based on one's previous experience had been perceived negatively for a long time, however, today this perception has changed as new valuation that imagination is the only the motive of human being's behavior patterns comes out. Meanwhile, green design means planning the healthy life in the future by finding the way that people and environment can live together. In order to realize green design in our lives, some plans which concern environment, style, and alternative technology of housing. Especially, in interior design, not only by technology skills but also by green visual environment, eco-friendly houses exist. Therefore, this study examines several elements which gives green atmosphere into the house, and understands how architectural imagination comes out in eco-friendly housing design through verify some examples.

Personalities. human relations. living patterns. and so on of the aged have been moulded respectively for a long period of time and their present situation of health. family make-up. economic condition etc. are different individually. Various characteristics - physiological. psychological and social peculiarities - of the aged are analyzed and studied in preceding paper to grope planning factors of architectural spaces by referring to sundry records from many branch gerontology, medical science. psycology. sociology. etc. - of knowledge in a position of architectural planning. So. in this paper. the directions of planning residential environment for the aged are studied on the base of those planning factors of architectural spaces. there are room(X$_1$). unit home(X$_2$), public housing(X$_3$), residential district(X$_4$) as dwelling spaces for the aged in X axis and safety(Y$_1$). hygiene(Y$_2$). convenience (Y$_3$), comfortableness (Y$_4$). psychology ($Y^5$), aesthetics ($Y^6$). society ($Y^7$). economy ($Y^8$) as the terms desired to spaces in Y axis. And the directions of planning residential environment for the elderly are studied by discussing mutual matters relevant to the subject on the cells of matrix formed by X. Y axis. In planning residential environment for the elderly. their physiological. psychological. social characteristics should be considered thoroughly and many types of dwelling spaces should be built. Then they can take up their abode to suit their conditions easily.
