This study aims to clarify the aesthetic values between emotion of human and expression of technology in contemporary fashion as it analyzes formative characteristics of related cases in fashion based on principles of 3D Printing technology and the viewpoint of mechanic aesthetics. The conclusions of this study are as follows. First, 3D Printing fashion is not only expressed diverse variations by its principles of formative methods, materials and properties, but also changes of silhouette by applying system of designers. Second, general characteristics of 3D Printing fashion is represented by various applications in SLS system, and it can be specifically explained application to a portion of clothing, decorative roles of clothing, complicated pattern making through crossing fabrics using 3D scanner and displaying a certain object changing fashion styles, and so forth. Third, the formative characteristics of 3D Printing fashion from the perspective of mechanic aesthetics is as follows. It can be analyzed as the integration of metaphysical values through compared symbolization of natural feature and technical evolution, partial dynamics and interactive velocity-based, formative combinations for abstract expression using architectural components, cosmos images and substantialized structures through images of organic space interacted human shapes. As the mention above, 3D Printing technology can creative a diverse area of fashion, and express images of new technological fashion through various works with continuous development of techniques.

Recently, the damaged concrete structures are often strengthened or repaired using the polymer concrete or the polymer cement mortar. In the repaired concrete structures at early ages, internal stresses could be developed due to the differential drying shrinkage of the repair material. Due to the difference of the thermal coefficients of the repair material and existing concrete, additional stresses also could be developed as the structures are subjected to the ambient temperature changes. Theses environmentally-induced stresses can sometimes be large enough to cause damage to the structures, such as debonding of the interface between the two materials. In this study, a rational procedure was developed where anchors can be designed and installed to prevent damages in such structures by thermally-induced stresses. Finally, through the experimental study and numerical study, the effects of the repair method using anchors with debonding was investigated and discussed the results.

The purpose of this study is to investigate the basic historical characteristics and its modern trend of Torajan traditional housing architecture in Sulawesi Province, Indonesia. The Toraja culture belongs to the cosmological culture with Cosmos centric characteristics. A traditional house, being called 'tongkonan' in Toraja region, is more than just a structure, representing the symbol of family identity and tradition. The Torajan architecture is a combination of the myth and cosmos, also regional conditions. With a short description of the general conditions and spiritual values of the Toraja, this paper explains the space-composition, the stylistic characteristics, the ornamental elements, construction, and its modern trend, etc. In general, it is raised on stilts several metres high, with a dramatically boat-shaped roof. Village layout varies according to size. The houses are arranged in a row, side by side, with their front gables facing north. Each house stands opposite its own rice-barn. The houses with their oblong ground-plans, built on piles set on stones. The interior is divided into three or four rooms, having few window. The houses are embellished with carving and paintings, and the facades display engraved and painted geometric and figural designs. The most frequent motif is the buffalo head, ranging from the realistic to the highly stylized. The Torajan traditional housing have experienced radical changes during the Modern period. In spite of the popularity of new modern house-styles, the traditional architectural style is often now constructed as an icon of Toraja identity. This paper will be helpful for understanding regional diversity of the traditional housing in Southeast Asia.

The residential environment is a place which reflects the gradual evolution of human consciousness because it is a cultural space the term, 'houses' is not relevant in this context as it literally means 'contains'. The long history of human living habits cannot be 'contained' within a space, but can be 'expressed' by a space and by the way the space is used. Furthermore, due to the way it is typically constructed, the basic characteristics of the house usually cannot be rapidly changed to accommodate new habits. However, recent changes that have taken place to the characteristics of the traditional master room suggest that traditional societal values associated with patriarchy have diminished. The current trend where priority is given to children's education also affects such a change. Existing researches related to the master room is confined to the behavioral use of the space and the composition of the physical space, while research on the master room its plane type has not been carried out. Therefore, in this study, apartment model houses are selected, and are classified according to the types of master room. An analysis is then carried out of the master room based on the occupants' requirements in terms of consciousness. Any planning modifications where required are then suggested. This research comprises the followings stages. First, an examination is carried out of existing research on the master room in order to understand its background and spatial components. A definitiones of related terms is also provided. Second, an analysis is carried out of the model houses exhibited at Suwan District, examining the typical standard that has been selected for the master room. Third, an analysis is conducted of the topics and questions to be selected for a questionnaire. Fourth, an analysis is carried out of the consciousness, satisfaction and requirements of the residents, as respondents in the questionnaire, related to the master room. and Research is then conducted of the architectural methods for planning the master room. Finally, future countermeasures for planning the master room are described based on the above analysis and research findings.

In the case of the fire outburst within a partitioned space, it can disappear inside it through smoldering process if the fire cannot obtain sufficient imflammability. On the contrary, if it obtains it, the fire is not restricted within the room, spreading to the higher levels beyond outside windows and the compartment room. The method to prevent the fire spread through windows is considered to build a balcony or equip with sprinkler facilities. This case study is to identify which effects and controlibility a balcony brings about on the spread of fire through a full scale model experiment. In order to understand the effects of fire spread on the upper levels of the room on fire by changing the length of balcony, the temperature was measured, radiant heat was investigated, and products of combustion were analyzed. The result showed that when fire occured, longer length of the balcony, which linked to the outside wall of the apartments, led to the blocking of the fire spread, lower level of radiant heat, and significantly less transfer of toxic gases, and the driving force of the outburst of flame was identified as the attractive force due to the turbulence of uncombusted gases, which exist on the upper level of the outbursting flame.

The previous studies argue that using the semantic properties of BIM objects is efficient for simulating the behaviors of autonomous, computer agents, called virtual-users, but such assumption is not proven via evidence-based research approaches. Hence, this present study aims to investigate the empirical effects of a human behavior simulation model equipped the semantics of spaces on the architecture-major students' operation and understanding of the simulation system, compared to a typical path-finding model. To achieve the aim, this study analyzed the survey and interview data, collected in the authentic design projects. The analysis indicates that (1) using a simulation model equipped the semantics of spaces helps the students' operation of the simulation, and (2) it also aids understanding the relationship between the variables of spaces and virtual-users (${\alpha}=0.74$). In addition, the qualitative data inform that the advantages of the simulation model that computes the semantics of spaces stem in the automatic behavioral changes of massive numbers of virtual-users, and efficient detection and activation on the what-if situations. The analysis also reveals that the simulation model has shortcomings in orchestrating the complex data structure between the semantics properties of spaces and virtual-users under multi-sequential scenarios. The results of this study contribute to develop a future design system combining BIM with human behavior simulation.

The visual expression system of space realized in Baroque aesthetics is basically grounded on the philosophical view to the world of the time, that is to say the changes of the thinking system in the Renaissance and ontology based on it. Structural aesthetics in Baroque freed from Plato's system of harmony but grounded on Leibniz's process philosophy formed a crucial background to highlight the formal nature of the whole and build a structure based on the inclusive principle of formativity. Also, to solve problems to realize the order and consistency of forms from the whole, Baroque adopted the nonlinear and nonphysical formative system as the principle of building space in works of art. Combining the order system of nature in the Renaissance with manneristic dynamicity as well as formative principle taking shape geometrically, it did establish a variety of aesthetic concepts based on the results of infiniteness and exaggeration expressed from the two forces, the Renaissance and mannerism. This study has found that such Baroque aesthetics did overcome classical planeness and draw continuous mobility from the structures and forms based on that with the transborder concepts of structures, the components of space, as an ultimate system of formative expression. Moreover, this author has drawn and analyzed with the cases of the 17th-century art and architecture the transborder elements manifesting the nature of diverse formative visual elements produced in artistic expressions with that principle of aesthetics, that is the intangible concept of Baroque. Based on that, this researcher intends to come up with technical solutions to solve a lot of environmental and architectural problems we are severely facing nowadays in terms of environmental, physical, and emotional aspects with the theoretical clues and results acceptable to this contemporary era.

The whole world has been damaged by dramatic increase of natural disasters such as localized torrential downpour, earthquake and drought, while suffering from climate changes caused by global warming. In Korea where the continental climate and oceanic one are crossed, the frequency and the size of damages are increased by stronger typhoons and localized torrential downpours and landslides, storms and floods. Therefore, this study analyzed damage cases and their causes and examined foreign plans to prevent natural disasters, by limiting to rural villages where serious damages occur due to typhoons and localized torrential downpours and measures and infra-structures against such disasters are poorly prepared. From the findings, it attempts to suggest some plans to establish disaster safety villages by abstracting plan factors applicable to rural areas in Korea, on the basis of facilities and spatial projects.

Multi-core processors can improve parallelism of application processes and thus can enhance the system throughput. Researchers have recently revealed that the processor affinity is an important factor to determine network I/O performance due to architectural characteristics of multi-core processors; thus, many researchers are trying to suggest a scheme to decide an optimal processor affinity. Existing schemes to dynamically decide the processor affinity are able to transparently adapt for system changes, such as modifications of application and upgrades of hardware, but these have limited access to characteristics of application behavior and run-time information that can be collected heuristically. Thus, these can provide only sub-optimal processor affinity. In this paper, we define meaningful system variables for determining optimal processor affinity and suggest a tool to gather such information. We show that the implemented tool can overcome limitations of existing schemes and can improve network bandwidth.
