The seismic vulnerability of stone masonry buildings is studied on the basis of their fragility curves. In order to account for out-of-plane failure modes, normally disregarded in past studies, linear static Finite Element analysis in 3D of prototype regular buildings is performed using a nonlinear biaxial failure criterion for masonry. More than 1100 analyses are carried out, so as to cover the practical range of the most important parameters, namely the number of storeys, percentage of side length in exterior walls taken up by openings, wall thickness, plan dimensions and number of interior walls, type of floor and pier height-to-length ratio. Results are presented in the form of damage and fragility curves. The fragility curves correspond well to the damage observed in masonry buildings after strong earthquakes and are in good agreement with other fragility curves in the literature. They confirm what is already known, namely that buildings with stiff floors or higher percentage of load-bearing walls are less vulnerable, and that large openings, taller storeys, larger number of storeys, higher wall slenderness and higher ratio of clear height to horizontal length of walls increase the vulnerability, but show also by how much.

In 1950, Anne $H{\acute{e}}bert$ published Le Torrent, a collection of seven short stories. These stories containing many shocking themes and expressions have placed her one of the pioneers of modern novels in Quebec. This paper tries to analyze several phases of alienation described in the novels and the reactions of alienated caracters in their situation. Some examples of alienated and mentally or physically deformed characters in Le Torrent are Fran?ois, $St{\acute{e}}phanie$, Stella, etc. Although the author wanted readers to interpret these characters on ther individual level, this paper interprets them differently. The result of this study is as following. Alienation doesn't come from one's interior but his exterior. Society and history are major agents of alienation. The injustice of life imposed on the caracters results from political and religious underdevelopment, cultural lowness, absence of social security system and of universal education at that time. The conquest of Quebec by England left a deep and historical wound on the French Canadians. This fact is, in my opinion, one of the essential themes of Anne $H{\acute{e}}bert^{\prime}s$ novels. In spite of all these alienating situations, the reactions showed by the caracters of the novels are limited to escapist illusion, self-destruction, mistaken revenge, eternal submission, etc. In conclusion, Le Torrent by Anne $H{\acute{e}}bert$ which deeply approached themes of violence and alienation could be called authentic landscape of the inner world of Quebecois before 'la Revolution tranquille.'

Recently, it is issued that the big data collecting meaningless data, and then extracting meaningful data from analyzed relationship to provide various information for users. However, original data collecting methods have difficulty in collecting information Because they analyze data by using sensors installed at exterior and interior of buildings and information of users. In this paper, we develop a data collection application using smart phone to resolve this problem. Developed application transmits data about Wi-Fi and measured information such as temperature, humidity, acceleration, gyro to server through web. The data transmitted is used as a context inference for users. According to the inference result, it is possible to provide various services on user conditions.

This paper presents experimental and analytical investigations on additional fixed-end rotations resulting from the strain penetration of high-strength reinforcement in reinforced concrete (RC) beam-column connections under monotonic loading. The experimental part included the test of 18 interior beam-column connections with straight long steel bars and 24 exterior beam-column connections with hooked and headed steel bars. Rebar strains along the anchorage length were recorded at the yielding and ultimate states. Furthermore, a numerical program was developed to study the effect of strain penetration in beam-column connections. The numerical results showed good agreement with the test results. Finally, 87 simulated specimens were designed with various parameters based on the test specimens. The effect of concrete compressive strength ($f_c$), yield strength ($f_y$), diameter ($d_b$), and anchorage length ($l_{ah}$) of the reinforcement in the beam-column connection was examined through a parametric study. The results indicated that additional fixed-end rotations increased with a decrease in $f_c$ and an increase in $f_y$, $d_b$ and $l_{ah}$. Moreover, the growth rate of additional fixed-end rotations at the yielding state was faster than that at the ultimate state when high-strength steel bars were used.

According to the statistical surveys and studies, insufficient maintenance in the use of existing buildings caused fire and collapse accidents. In this respect, I analyzed the data managed by the current building maintenance and inspection system to find out the actual state of safety management and proposed two significant results. First, regarding the state of the buildings, the safety management status of the small-sized ones, where 20 years or more passed after construction, is the worst and a priority improvement plan is required. Second, there are eight deeply concerning factors for the fire incidents and collapse accidents of buildings. In the order of high risk, these factors are structural strength (seismic design), exterior wall finishing material, basement floor, interior finishing materials, other evacuation facilities, corridors stairs entrances, rooftop, fire partition. We need to have more special designs and management plans regarding high-risk factors as a system to prevent accidents in the building.

This study aims to identify convenient surrounding of the hospital room to be improved by specifically focusing on light environment and to examine a change of inflow of the daylight in the hospital room by using blind and light shelf device as base data of preliminary research for comprehending the relationship between healing environment and natural day light. Simulation analysis on previous facilities and the installation of horizontal light shelf that derives the inflow of day light has been specifically referred by using ECOTECT2011 program. In case of C-facility that mostly adjoined to exterior spaces, it was shown to be closer to a proper uniformity factor when an angle was controlled on the light shelf with blind installed at the same time. However, it was not overall appropriate because of visual displeasure occurred from inflow of much day light. In conclusion, it is the form of flat surface such as H-facility that provides an effect after installing the device to derive day light. Especially, it was shown that interior day light environment was improved when installing blind and controlling the angle at the same time.

This paper presented analysis on the perception by Korean restaurant employees of Korean royal cuisine. Classification using a subjective research method called Q methodology was performed on perceptions of Korean restaurant employees about Korean royal cuisine. This paper derived four types of perceptions. First type (pursuit of tradition) emphasized traditions of royal cuisine, i.e. cooking method and spacious menu-setting on the table. The second type (pursuit of refinement) stressed the importance of "atmosphere and luxuriousness of Korean restaurants and sophistication of royal cuisine, as well as the improvement of interior and exterior environments of Korean restaurants serving royal cuisine. The third type (pursuit of fundamentals) focused on fundamentals of royal cuisine itself such as raw materials, sincere effort, historical meaning, appropriate prices, etc. The last type (pursuit of health) valued a nutritionally balanced diet rather than taste itself. This study provides more specific positioning strategy based on the characteristics of each of the four classifications for the status of Korean restaurants.

Smart windows are used as windows and doors to determine the cooling and heating efficiency of a building. They have characteristics that can increase the energy efficiency of a building, which leads to energy savings. In addition, smart windows can control the amount of light transmitted from the external environment of a building to the interior of a building according to the needs of the user. In this study, a 297×210 ㎟ liquid crystal cell capable of controlling light transmittance was fabricated using a liquid crystal device as an optical shutter. The effect of driving voltage on the transmittance and the effect of the thermal environment on the driving stability were analyzed. We confirmed the applicability of using smart windows as exterior building materials.

This study aimed at revaluating Frank Gehry's freeform constructions. To this end, the study analyzed the way the space composition and circulation system of general constructions are connected with newly extended parts in the Art Gallery of Ontario and, based on this, comparatively analyzed freeform constructions before and after the art gallery, finding out what changes were made in the exterior and interior spaces of freeform constructions built after the art gallery. The results of the study are as follows. First, starting from extending the Art Gallery of Ontario, Gehry came to use glass instead of metal as main material of freeform constructions. In order to create the circulation connecting the existing building and the extended mass, Gehry applied continuing circulation for the first time to the gallery. Third, in addition to design motives, such as the woodblock print depicting a carp by Hiroshige, still life depicting a glass bottle by Morandi and the crease of the shawl in Vermeer's paintings, which Gehry applied to freeform constructions, the design motif which was recently acquired from Pyrenees rock was added. Fourth, the trend of mall construction appeared before and after the Art Gallery of Ontario. Finally, Gary used the shape of fish as a design motif for his work at an important turning point in his Freeform Architecture.
