This study aims to provide preliminary review for standardization of methods for evaluating reduction performance of pollution-reducing building materials and to select commercially available pollution-reducing building materials for assessing their current status. The ISO 16000-23 and -24 standards were used as references for standardizing the test methods. The sub test categories—stability of the supply air concentration, type of the supply air, and supply air concentration—which were not included in the standards were selected and conducted for the purpose of this study. Five (5) wall materials and 2 ceiling materials were tested for formaldehyde reduction performance and 3 wall materials were tested for toluene reduction performance. The study included experimental review of the essential test criteria such as stability of the supply air, internal stability of the chamber, and recovery rate. The samples tested exhibited some reduction performance for formaldehyde but little reduction performance for toluene.

This study fouces on the electricity generation of B1PV system in the super-tall buildings. To improve the efficiency of the B1PV system, solar irradiance and air temperature should be taken into consideration. This study does research on, one of two main parameters, the solar irracliance in the super high-rise buildings. According to the measurement of solar irracliance, it increased with altitude. It is, particularly, more obviously in the super-tall buildings than others. Subsequently, to make an accurate B1PV elecrticity generation prediction，it is necessary to anaiyze the solar irracliance distribution on the super-taII building's facade which is a prerequisite for optimal B1PV system design.

With the trends of massiveness and complexity of construction, the main agents of construction have considered the various types of risk management strategies to minimize the loss caused by the risk factors from the nature of construction project, regional characteristics, and scale of construction. The risk management has been conducted, because the risk factors have exacerbated the condition of construction in terms of the level of productivity, quality of construction, atmosphere, and budget. Based on thε interests regarding risk factor management, the current study suggests the work breakdown structure-based process. Additionally, based on the work breakdown structure, the risk factors on constructions are identified and stratified depending on the level of salience of each risk factor. The purpose of result is to lead Korean Land Corporation understand and control the risk factors properly for the advanced construction process of Korean Land Corporation. Ultimately the current study contribute to advance of efficient risk management strategies by using ANP method, which identify and control the primary risk factos depending on the impact of the interaction and subordinate relationship between risk factors.

Western style timber roof trusses used as typical roof structures of buildings during a modern period have been developed with the interactions with their facade and functionality. The shapes of trusses and member sizes have been diversely changed by the purposes of architects, historical circumstances, and structural characteristics. For this reason, the change in the shapes of western style timber trusses along the times is one of important technology assets demonstrating the development of their structures during the modern period. Therefore, the purpose of this paper is to find out their structural characteristics throughout parametric analysis of which parameters were determined from the collected and classified documents on western style timber roof structure built in the modern period carefully obtained from public institutions. Results of the parametric analysis are as follows. The number of king-post trusses and modified king-post trusses built between 1920 and 1937 reaches almost half of the total number of truss types investigated. The mean values of their spans, distances, tributary areas, and height are respectively, 10.5m, 2.4m, 24.37㎡ and 3.24m. The cross-section areas of trusses tend to reduce since the city construction law was enacted in 1920. Also, this study found that western architects usually used larger structural members than eastern architects and usages and finishing materials of roof trusses are not always considered as one of the important design parameters.

Imre Makovecz, a Hungarian architect, has chiefly known for his unique organic works. He has taken a lot of sharp criticism against mere functionalistic and stylistic approaches toward modern architecture. Instead, he has desired to pursue a true embodiment for organic beauty and hungarian cultural heritage in architecture. Although most of his works reside in Hungary, he has become an internationally recognised architect for his unique works. This article attempts to identify Hungarian culture and its influence to Makovecz's architecture. It also examines how Makovecz investigated Hungarian folk art traditions and primitive craft patterns, and then applied the lessons learned into his own architectural designs. Then, this article attempts to expose the principles of his organic architecture deeply influenced by the philosophy of Rudolf Steiner. Finally, it concludes with a discussion of the benefits and challenges of employing similar approaches for the development of a rich architectural tradition.

Project owner, asbestos removal specialist, experts on asbestos removal work, as counter parts to be defined in the study to make out research goals have been asked with questionnaire survey and replied with 65, 275, 32 cases, respectively. And additionally, direct interview 73 sheets have been collected to find out current status of required engineers and equipments assigned and provided to the field, from them, three(3) concerned parties. Questionnaire subjects are composed of common items, reasonable unit cost, need of separate contract-awarding system, status of performing standard contract, status of providing legal engineers and equipments. Concentrated review of two~three questions by subject has been made to find out and compare idea results between three(3) concerned parties. First, legal and practical work status survey have been made to determine reasonability of introducing separate contract-awarding system, as a part of ensuring reasonable unit work cost. And then, two different status have been compared and there is introduction possibility of separate contract-awarding system, it is found out. The possibility of separate contract also has been confirmed by comparison of domestic legal grounds. Justificating grounds to introduce separate contract-awarding system have been shown. Standard contract status between asbestos removal specialists has been compared using two cases of providing removal work contract and receiving it. It is shown that case of 50 percent or less contains 38.5% when they receive contract, but only 10 percent reduction of original contract amount has been made when they provide it. It means that asbestos removal specialists do not keep occupational safety and health regulations.

Contrast a general building high rise buildings itself has a kind of risk. In this study, the risk of a number of high rise buildings have fire fighting safety management of the particular risks associated with looking for ways to minimize focused. Issues include self fire protection. disaster management, building code and fire code of the mismatch, such as fire protection facilities aspects are explained in terms of three kinds, and for it to take steps in the direction suggested an alternative for high rise buildings. Although differences of opinion between departments will not be easy to fire fighting and building codes regarding conflicts of codes above all require immediate resolution, and high rise buildings to create a standard for effective risk management manual countermeasures will also be ensured.

Based on travel literatures written by the Joseon literati, the different picture of seventeenth- and eighteenth-century Buseok monastery from the one today emerges. Not only do the buildings removed from the monastery today reappear, but the quite different way of the monastic operation comes to light. This observation leads to a speculation that the monastery was functionally and spatially divided into two territories; that of the Immeasurable life hall and of the Dharma hall. The Immeasurable life hall's precinct was built at the site open to the west providing a grand vista of mountainous area. This siting, originally having a close relation with the visualization such as the Sixteen contemplation, not simply gave such a special attraction that the first built architectural composition has lasted through the centuries to the late Joseon, but also granted to the Chwiweon pavilion located at the western side of the precinct a special meditative quality. As the monastery has suffered from a number of heavy duties in the Joseon period, the architectural attraction of the precinct was mobilized to promote the monastic identity as the legitimate monastery first built by Uisang, the founder of Hwaeom Buddhsim. Especially, the Chwiweon pavilion offered a mental space so that the literati might form an affirmative attitude toward the monastery and the monks. The Dharma hall's precinct was built based on the direct replication of the architectural layout presented in liturgy books for the Water and Land rite as well as the Vulture Peak rite. This layout is generally called the Court-type enclosed by four buildings, which has been widely fashioned in the late Joseon period. This characteristic gave to the Dharma hall precinct an arbitrary and anonymous quality, which helped not only avoid the tourism of the literati, but also secure the sacrality and ritual efficacy at occasions of Buddhist rites. This division of territories of the monastery can be understood as the strategic reaction from the monks in order to survive in the age of oppression against Buddhism. In result, the identity of Buseok monastery in the late Joseon was established as the Nine-rank sanctuary where Bodhisattvas permanently resided.

The goal of this paper is to analyze the relationship between pedagogy and the emergence of contemporary Korean architecture after the 1990s. For this purpose, the paper deals with the education and work of two important contemporary Korean architects, Kim Seung Hoy and Choi Wook. Kim and Choi were part of a group of young architects that went abroad in the 1980s to study at the centers of architectural education in Europe and the United States. Through their education and work, the paper discusses the relationship among education, history, and design practice in architecture. During their studies at Michigan University and IUAV in Venice, they were commonly influenced by Colin Rowe through their studios. In the case of Kim Seung Hoy, he was introduced to the Beaux Arts logic of the analytique and esquisse through the teaching of Steven Hurrt, a disciple of Colin Rowe. Choi Wook took studios that involved formal analysis and comparison of Palladio and Le Corbusier. The paper further analyzes their works in Korea by employing the concepts of fragments and systems, ignorance and knowledge. The paper concludes that, in Korean contemporary architecture, fragments and systems, ignorance and knowledge, lie in the middle of ongoing creative process that must distinguished from the West, where architectural history provides an established tradition of systematic knowledge.

Many animals are capable of detecting sensory information emitted by predators. When predation risk is high, orb-web building spiders should change its foraging strategy of the web construction. We examined web building behaviors of an orb-web spider, Argiope bruennichi providing sensory information of its predator, a yellow hornet, Vespa simillima. We observed web characteristics after providing sensory information of the yellow hornet (experimental group; N=29) and compared to the control group (no information provided; N=34). We hypothesized that the spiders in the experimental group would decrease investments in its web construction and stabilimentum decoration to avoid being located by the predator. The results rejected our hypothesis. Web and stabilimentum constructions decreased in the course of the experiment in both control group and experimental group. But the differences between control group and experimental group were not significant. The individuals did not reduce its stabilimentum length and did not decrease its web area in spite of sensory information of the predator.

The Axes and Adzes are the oldest tools since the beginning of human history which is used to cut the tree and make part of architecture such as boards, square timber etc. Nowadays, these old woodworking tools especially "Jagui(자귀)" (adze) has been almost disappeared at the working site of residential and cultural properties. It is necessary to study Korean traditional woodworking tools to keep Korean traditional skill and technology. It has been reviewed the change of shape of "Jagui(자귀)" (adze) from before Samhan (삼한) period to Joseon Dynasty through excavated relics and paintings and summarize as follows: Based on excavation relics of Dahori, both plate type blade and pocket type blade are used for "Tokki(도끼)" (axe) and "Jagui(자귀)" (adze). The excavated "Jagui(자귀)" (adze) from Jeongbaikri 356 tomb, near Pyongyang is prototype of "Jagui(자귀)" (adze) used nowdays which has almost same shape as well as the insert method of blade and handle. The auxiliary handle is inserted to blade and the main handle is inserted to the auxiliary handle which is different from the method of Chinese and Japanese "Jagui(자귀)" (adze). The length of handle of "Jagui(자귀)" (adze) until late Joseon Dynasty is short by which we assume it is used for a sitting position as hand held Jagui and from that time long handle has been introduced for a standing position which is called "Sunjagui(선자귀)". "Jagui(자귀)" (adze) has been used since the beginning of human history but it is almost disappeared at the most of woodworking site which is the crisis of Korean traditional architecture and we have to do something to keep it.

This study primarily aims to illuminate the characteristics of Meoreum in Korean traditional fitting system according to the respective types and its periodical changes. Using the research findings as a chronological indicator by which to estimate the construction date of the building is the secondary purpose. In this study 42 of Byeoldang and pavilion architecture remaining in Yeongnam district were examined through the field surveys and methods of documentary research. The research results are as follows. First, Meoreum, which is located below the windows or doors, provides protection against the outer wind and has the function to prevent some warm air of the room from flowing outside. Second, Meoreum was recorded as Yoeum(了音), Woneum(遠音), and Maleum(末音) in Yeong-geon-ui-gwe (營建儀軌) of Joseon period. While Yoeum(了 音) was used in Yeong-geon-ui-gwe (營建儀軌) of 1776 and 1856, Woneum(遠音) had been also used continuously since the year of 1800. The word, Maleum(末音) can be seen in Lim-won-gyeong-je-ji (林園經濟志), published in 1827. Woneum(遠音) and Maleum(末音) seem to be the Yi-du(吏讀) types of expression of Meoreum which is being extensively used now. Third, the kinds of Meoreum can be classified as TohMeoreum, TongMeoreum, TongpanMeoreum, and J janeunMeoreum. TongMeoreum and TohMeoreum were mostly used at the front part of Ondol-rooms, the backside of main floor called Daechung(大廳), and at the space between Daechung and rooms in the Pavilions and Byeoldangs(Annexes) that had been built in the early Joseon dynasty. TohMeoreum was usually used at the bottom parts of windows between Daechung and Ondol-rooms. TongpanMeoreum was mainly used in the mid-Joseon period and relatively high height was the distinctive feature of Meoreum at that time. J janeun Meoreum, used mainly in the late Joseon dynasty, has become lower and lower gradually in height since 19th century, so people could enter the room through the windows(fittings). Such changes in Meoreums types has brought about the flow of human traffic directly from Toenmaru, narrow wooden porch running along the outside of a room to Ondol-rooms.

With the place which concentrates vertical traffic facility and equipment which are a core facility etc. there is in a building and with structure major role. The core is cold under effectiveness of the area and elevator system with security of the business space which is the relationship which is close in high office construction MIDAS GEN and used the identical construction infrastructure where the core location is different in order to influence is direct in dwelling environment animal power, shear force and moment it used structural analysis. It used a load standard and it compared after grasping a safety and a use characteristic, the core reaches in the building problem point the top class bringing up for discussion Drift Value and escape. The result which it analyzes with base there is recently to high office plan and it decides a core location to be, it presented in about plan of optimum. The central core in large scale and rough copy layer is suitable in the office, the case frame peripherally with the historical wall there is an effect which is stabilized with structure, the eccentric core in the small-scale office suitability but is disadvantageous evacuation facility and equipment establishment etc. The core in standard will grasp a stability in about durability and load of absence, it means it will be desirable to reflect to a high office building plan with the base which will reach.
