Demand is increasing for large, high-rise, and complex buildings, which is leading to advances in the development of high-performance structural systems. In this context, precast concrete (PC) technology has received a large amount of attention owing to its benefits in terms of schedule reduction, high quality, and easy installation. In addition, advanced methodologies that improve the PC performance by the addition of various materials have recently been reported. Research on analyzing the effects of such high-performance PC on the construction process and productivity is very limited. This makes it difficult for decision-makers to apply PC to particular projects. Thus, the aim of this research was to analyze the work productivity of the high-performance PC slab installation process by using a construction simulation tool to resolve critical issues. In this study, a real construction project that adopted PC slab installation work was analyzed, and a sensitivity analysis was performed to confirm the reliability of the analysis results.

Architectural embodiment of a national identity has long been a significant topic in Korean architectural circles. For this reason, it must be helpful to examine the so-called, 'National Romanticism' of Finnish architecture around 1900 in that Finnish architects of the time struggled to embody their national identity through their projects. Considering the historical and linguistic affinities between Finland and Korea, the Finnish architectural situation draws . our additional attention. This paper aims at showing its historical background, the meaning of each type of buildings in the stream, and limitations it implies. The atmosphere of Finnish nationalist movement, which was provoked by [Kalevala] publications (1835; 1845) and shown in Karelianism, was heightened by Tsarist Empire's Russification programme of Finland in the late 19th century Architecture was one of the most important genres expressing her national identity. Finnish national romantic architecture could be divided into three. The first is a log house style for artists' studio house, motivated by the Finnish vernacular farmstead - especially by Karelian farmhouse. This type of building signifies the Finns' will to return to their motherly soil. The second is a stone architecture style for public buildings, inspired by Finnish church or castle of an early medieval time. By using roughly-cut granite as the main exterior material, buildings of this type symbolise the toughness of legendary heroes and Finns' desire for national Independence. The third type of building was based on both of the former or more dependent on architects' Imagination and creativity. However, Finnish national romantic architecture has been criticised by some critics owing to its decorative, eclectic and self-indulgent characteristics. Probably, it was not really national but rather inter-national because of the Influences of English Arts and Crafts Movement, the American Richardsonian architecture and the continental Art Nouveau. And the negative images of 'national' and 'romantic' made some historians coin other terms like 'national realism' or 'material realism'. As another limitation, one raises the low degree of its contribution to the entire architectural history. Despite these criticisms, however, this paper argues that Finnish national romantic architecture is meaningful in itself, particularly because it illustrates vividly Finns' struggle to search for their national identity and, after all, their craving for national independence.

The United States understood the fostering of pro-U.S. elites in "free world" countries as an important Cold War weapon. From 1954 to 1962, the U.S provided considerable assistance to Seoul National University (SNU) for its postwar rehabilitation and future development in terms of repair and construction of campus buildings, equipment and book purchases, and faculty exchanges. With the aid of this educational assistance project widely known as the Minnesota Project, SNU was reborn with an academic orientation to the U.S., separating itself from the Japanese education that was its origin. This study argues that the Minnesota Project played an important role in crafting SNU's architecture program and the exchange program's recipients as key "knowledge brokers." For individual trainees, experience in the U.S., as opposed to a backwards situation in their homeland, had allowed them to recognize the U.S. as an ideal source of knowledge. Since the Minnesota Project, SNU's Architectural Engineering Department was filled with faculty members who had trained or studied in the U.S., which became a significant distinction of SNU's architecture program in sharp contrast to its counterparts at Hanyang University and Hongik University where most of the faculty members studied in Japan during the Japanese colonial period. As many graduates of SNU had been appointed as faculty members in newly-founded architecture programs in South Korea, a hierarchical diffusion path had emerged in architectural education that led from SNU to other school's architecture programs, with the U.S. at the apex. The legacy of the Minnesota Project extended over the next few decades, in which studying architecture in the U.S. was recognized as a shortcut to success in the field.

Fahion as the form construction of decon-structivistic architecture was analyzed by dividing it into the intrinsic aspect and the formal aspect through an introduction of three characteristic architectural principles into fashion. Intrinsic deconstructivistic fashion as the construction of architectural form has the mixurte of genders both in a form of transvestic and in a form of genderless look as dualism, and can be characterized by pluralistic nationlism with the emergence of the Third World alienated from the international society, and so forth. Difference and the prefixes of dis-and de- are schizophrenic mystic illusionism, chance effect and the differance of space and time and is supporting Jacques Derrida's chiasmus that is the perspective of collage in painting and the multiple observation of collage in painting and the multiple observation point as the play of borrowing the surrealistic technique. The formal construction of deconstructivistic fashion the construction of architectural form has intertextuality material, hybridization of items and the blending of modes and another sphere. Trace as icon deconstrucion attains historical analysis. Dis and de in fashion are showing the retrogre-ssion of gravity through decomposition, decon-tinuity and disjunction emerge nonstructural silho-uette, juxtaposition, inversion and replace- ment of underwear and outer garments. Their decentring expression emerged as construction through mixture and repetition as well as overlapping of planes or spaces. And their disjuctive representation appeared in the form of mutual juxtaposition and substitution with the double-side of formal construction in functional terms.

A ductility inverse-mapping method for SDOF systems including passive dampers is proposed which enables one to find the maximum acceleration of ground motion for the prescribed maximum response deformation. In the conventional capacity spectrum method, the maximum response deformation is computed through iterative procedures for the prescribed maximum acceleration of ground motion. This is because the equivalent linear model for response evaluation is described in terms of unknown maximum deformation. While successive calculations are needed, no numerically unstable iterative procedure is required in the proposed method. This ductility inverse-mapping method is applied to an SDOF model of bilinear hysteresis. The SDOF models without and with passive dampers (viscous, viscoelastic and hysteretic dampers) are taken into account to investigate the effectiveness of passive dampers for seismic retrofitting of building structures. Since the maximum response deformation is the principal parameter and specified sequentially, the proposed ductility inverse-mapping method is suitable for the implementation of the performance-based design.

The harsh economic conditions of Buddhist temples in late Joseon dynasty, and the prevalence of the Buddhānusmrti(念佛) practice, which is a practice of reciting Amita Buddha(阿彌陀佛), led Buddhist temples to organize the Buddhānusmrti association(念佛契) in the nineteenth and early twentieth centuries. For the practices and the activities of organization, an architectural facility was required; thereby, many temples had a Yeombul-dang(念佛堂). However, only a few of the Yeombul-dang have survived and are known today. This research investigates the ways temples tried to acquire Yeombul-dang buildings during the period and their architecture characteristics by reviewing historical records and documentary works of literature. In this research, Yeombul-dang is found to have various types of building names and building forms. Different hall names such as Amitābha Hall(佛殿), Yosa(寮舍) and Daebang(大房) were used as Yeonbul-dang. The commonalities and differences in terms of building forms, spatial elements composition and layouts were found depending on how they were acquired. The Yeombul-dang were most commonly built as multi-complex buildings consisting of worshiping rooms and residential areas. Most of Yeombul-dang were located in the central areas of the temple site. On this basis, this research suggests the possibility that many Yeombul-dang is still being used under different names and for different purposes.

Recently the population to enjoy leisure time has increased, due to the advancement of income level and increase of spare time. In the meantime, the growing attention to well-being life has shed light on Han-ok or traditional Korean house. Such a social background as former, the growing number of people prefer staying at Han-ok style accommodation when they are enjoying leisure time. However there has been little substantial study or survey on architectural standards of Han-ok style accommodation because it is a new type of accommodation facility. Therefore this study aims to suggest a set of basic standards on architectural planning for Han-ok style accommodations. For this purpose, it investigated architectural planning on Han-ok style accommodations in Jeollanamdo province through on-site survey and interview to classify them based upon size and scale of the facility, layout of buildings and interior spaces in terms of function, elevation and materials and to find basic standards on architectural planning of Han-ok style accommodations.

This paper attempts to identify the term "tectonics" comprehensively by collecting and categorizing existing definitions of tectonics within the architectural area rather than to stress the concept of tectonics of each specific theorist. Although no consensus of opinion on the concept of tectonics exists, architectural tectonics was closely related to the following terms in three categories: 1. $techn\acute{e}$, technique, and technology; 2. construction and structure; and 3. stereotomics. Based on its etymology, system, and material construct, the notion of tectonics common in these three categories signifies "the art of framing construction," in which linear elements are connected with joints and clad or infilled with lightweight material. Thus, the art of framing construction, as a common concept of tectonics, reveals the following characteristics: First, tectonics is based on framing construction in contrast to piling-up construction as the etymology of tectonics signifies the art of carpentry. Then, the term tectonics, dealing as it does with a higher level of construction rather than the mechanical level of structure, incorporates the poetic aspect of techne as well as the rational aspect of technology. Third, Owing to the organic, double system of tectonic frame and incrusting or infilling materials, the tectonic body becomes both the ornament and the structure simultaneously. As the art of framing construction is based on material construction rather than structural or ornamental form, this paper proposes that one can view tectonics as a term that conveys the meaning of the actual material effect on space.

Due to increasing competition of construction companies, it is required to optimize the management of construction projects and "lean" concepts are rapidly spreaded in construction industry. Steel work accounts for a large proportion in construction work, and a variety of attempts to efficiently perform steel work has currently made. And since rebar (Engineer-to-Order) can be engineered through design once order is placed, it gives the great impact on construction, thus, entire management is required. The purpose of this study is to present the method to increase the efficiency of field processing method of steel work in terms of lean construction. Once we examine process of steel work and identify the flow, we would like to analyze which processes should be improved through value analysis approach and present the improvement plans. Also, this study examines cases of field processing and factory processing, and it identifies the waste factors in the procurement process. Finally, this study would like to present the result of analysis from the perspectives of value. The rebar delivery process is divided into several steps and the duration of every step is surveyed. Using duration data, VAT (Value added time) can be calculated for analyzing the efficiency of the process.

This study is focused on the evaluation of thermal output of TABS (Thermally Activated Building System). The aim of this study is to evaluate TABS in terms of the temperature difference between heating medium supply temperature ($T_s$) and return temperature ($T_r$), thermal output and the surface temperature distribution according to the design flow rate and the design flow temperature. Through the transient heat transfer simulation using temperature calculation using Crank-Nicolson FDM using Physibel Voltra 6.0 W, the temperature difference between $T_s$ and ��$T_r$, thermal output and the surface temperature distribution of specific TABS was calculated and evaluated. The results show that specific thermal output and temperature difference at $60^{\circ}C$ of supply water temperature were about 162 $W/m^2$, $13.6^{\circ}C$ respectively.
