This paper is a preliminary study of architectural characteristics of Jangdae (general's podium), which shows one of the technical changes in fortification of Joseon Dynasty. As a facility for commands of generals and training for officers and men, it was located inside a fortress. Although it is not certain when the first Jangdae was built, the number of them dramatically increased around 18th century. Since the top priority function of the Jangdae was the prospect, it was installed at the hilly spot with open architecture. In addition, the open structure of Eupseong fortress towers on the riverside banks could simultaneously offer the functions as viewing around and Jangdae. Since Jangdae was also a place for military drills and reviews of soldiers, a wide podium was positioned at the front to muster the soldiers. This feature was standardized in the space organization of Jangdae in Joseon, and a mere podium was installed unless the topographic restrictions allows enough space. On the other hand, as a place for a commander, the hierarchy of the Jangdae was revealed through a variety of architectural characteristics. The hierarchy was assigned to the commander's space through the altitude difference, and diverse ornaments were added to show a sense of class. The floor plan of the Jangdae building can be largely categorized into rectangle and square, and the typical sizes of the former are $5{\times}4$ Kans (traditional measuring unit between two columns) and $3{\times}2$ Kans. Out of these two types, buildings of $5{\times}4$ Kans were found in flat land and eupseong fortresses with large space, and the relatively smaller ones of $3{\times}2$ Kans in mountain fortresses. All buildings of square floor plan had $3{\times}3$ Kans style, and the center Kan was twice wider than the side Kan to make the central space wide. It seems that the purpose was to secure the interior space of the upper story because the center Kan accounts for the floor area of the upper story. Some Jangdae's had internal story to form overhead space. The multi-roofed tower style with eaves attached to the upper and lower story is found exclusively in Jangdae. The buildings shows the Onkanmulim style which extends Naejinju (inner column) of the lower story to be the Byeonju (outer column) of the upper story, and the log-framed floor in the upper floor was structured by inserting the Changbang (connecting beam) between the Naejinju's and joining the log frames. In addition, the towers in eupseong fortresses had log-framed floor in the upper floor by setting up the high Nuhaju (column underneath a roof) and joining Cheongbang to the upper part of the column while it cannot be regarded as multi-roofed because only the upper part has a roof.

The Mireuk Temple Stone pagoda is the largest scale of the existing Stone Pagoda in Korea. A research until now postulates that the Stone pagoda at Mireuk Temple site is composed of nine stories total. However it does not have any records of the detail, dimension, and related methods, etc, even though it is a tectonically large scale building. Only one source of the description is based upon a story which is a sort of Korean myth or traditional story (Samkukyousa, Mu dynasty), although a historical description from a myth or a story is a polemical issue and still needed research in order to prove the truth. One of the ways to make a proof of the truth is an architectural research from the typology of the plane. The types of the plane are differentiated from each era. Therefore, the typology of the plane presents a reason or a proof for the age of the pagoda. Furthermore, the typology of the plane is crucial part in the research of the historical style and it could help the historical style of the Mireuk temple stone pagoda. Research until now shows that the Mireuk temple stone pagoda is the genesis of the stone pagoda shaped after wooden one. It is impossible to find any previous one from the stone pagoda at Mireuk Temple site in Korea. So it is easier to find any previous example from the history of China because Buddhist pagoda-most pagodas are something to do with Buddhism-in Korea is introduced by India via China. This research presents the periodical variation of stone and brick pagoda in both countries. It concludes that the Mireuk temple stone pagoda has $7^{th}$ century's plane type.

This study has its purposes on analyzing specific features of the elements according to scales of 32 main buddhist sancta among wooden temples with gable roof that are nationally designated as cultural assets, and analyzing influences and proportional relations between main and submaterials, so that it could be basic and objective data for restore and repair cultural assets in the future. Results of the study are following. First of all, the average plane proportion of doritong (facade) and yangtong (side) in 3-room building is about 1.31:1, while it is 1.70:1 in 5-room building. Secondly, as a result of analyzing the locational proportion and thickness of pillars at each location, floor room turned out to have wider space between pillars than that of edge room or side room in both cases of 3 and 5-room buildings. In the mean time, for the average thickness of the pillars in 3-room building, it was 491mm for corner pillars, 433mm for general pillars in cases of 3-room building, while it was 595 and 511mm respectively in cases of 5-room building. The reason why corner pillars are 60~80mm thicker than general ones in average, is determined to considered structural stability and optical illusion. For the third, as a result of analyzing the influences on pillar thickness, eaves projection and eaves height according to the scale(dimension) of buildings, 3-room buildings have outstanding correlation as its scale(dimension) goes bigger, while 5-room ones are not very much influenced by its scale(dimension). For the fourth, as a result of the relation between pillars and eaves, both of 3 and 5-room buildings have longer-projected and higher eaves as their pillars go taller; especially height of eaves turns out to have very close relation between length of pillars. In addition to that, both of 3 and 5-room buildings have much projected eaves as the eaves go higher.

The demand for the lightweight wall has increased as the structure of the multi-unit dwelling has shift to the rahmen structure. The lightweight wall is required to secure certain degree of shock resistance for the structural safety. The study performed the load analysis test for 7 small hard bodies with different masses and shapes and 5 hard materials which applied the impact load on the wall. It was found out from the experiment that different pendulum weight doubled the load maximum even though the shock energy was the same. In addition, the study compared and analyzed the weight of materials and the load of small hard bodies to propose fundamental data for the material design of the lightweight wall.

To meet changing education needs due to globalization, interdisciplinary convergence, and ICT development, it is necessary for engineering disciplines to provide student-centered education. Not only do teaching methods using ICT reproduce teaching contents in a digital format, but they are also expected to be effective media for constructive student-centered learning whereby learners build knowledge themselves. The aim of this study was to develop a tool for safety education using virtual reality technology. To achieve the objectives, the author defined the requirements and constraints of the tool, and implemented a 3D educational tool in a virtual reality environment. A pilot test with 10 students showed positive results.

As Sri Lanka Stupa had been affected by Indian stupa directly, understanding Sri Lanka Stupa is important to know about the flow of Buddhist Art History, which is showing the variation of Initial Buddhist stupa. Due to invasions and disasters, all Sri Lanka's Stupa collapsed and became random mound. After restoration works, Stupa shape changed dramatically from the Initial shape to Existing shape. Since it is hard to find out how Initial stupas were like, Sanchi Stupa needed to be an example for the comparative study as an Initial shape. Sri Lanka Stupa have Square foundation and 3 Basal rings that are supporting the Main Dome. Entrances are on all 4 sides, Railing and Torana(gate) has never found in Sri Lanka stupa. Sri Lanka stupa has been classified with the shape of Dome into 6~8 types according to "Vijayanta Potha", the Ancient Buddhist Description, and described by several researchers confusingly. With the inconvenience of using unfamiliar words and irrational gap between the Initial Sri Lanka stupa and Existing Sri Lanka stupa, proposing new classification of Sri Lanka Stupa is necessary. Existing Sri Lanka Stupa can be classified into 4 types : which is (1)Bell type, (2)Pot type, (3)Mound type, (4)Bubble type. This suggestion is for further studies to use Easier and shorter words to describe the types and make it reasonable to use, since the current classification includes 3 stupa types even there is no case for any of them. Restrict Stupa Classifications within existing Sri Lanka Stupa is needed because the current classification had been continued for hundreds of years without any adjustments. Bell type is mainly located in Anuradhapura. Pot type and Mound type is only found in limited area, and Bubble type is located in most area of Sri Lanka.

In this study, it was analyzed that, the way of securing publicity and privacy in family and type of public space of the Japanese contemporary detached house, by the composition type of family from one person home to four generation family home. Mostly the living room is made as open plan of LDK type. Mostly, the entrance hall is separate with living room. Even if the case of the entrance hall is connected with living room, it is planned to be recognized as entrance hall, by making entrance poach or connecting it with stair hall. In many case, the public space is designed as traditional Japanese style, such as wellhole style space (吹拔け), courtyard, and Japanese style room (和室). The Japanese style room is adjacent to living room, and used as the space of receiving guests. The wellhole style space and courtyard are recognized as the center of the house, and used as buffer space for ensuring privacy of each generation. The most different point between bachelor house and multi generation family house is another LDK space, living room or kitchen for parents' generation is made separately. Particularly there are many case of making separate small kitchen space, therefore it can be known that, the separation of kitchen space is recognized more importantly than that of living room. And there are many case of making separate entrance hall, two houses under one roof. The spatial composition like this can said as rational method of ensuring the privacy of each generation, and using the public space together as necessary.

Pagodas in Myanmar can be largely divided into Zedi and Pato. Zedi is a developed form of the early domed pagodas in India and Sri Lanka, which can be found in the introduction of Buddhism in Myanmar and the comparison of early pagodas in India, Sri Lanka and Myanmar. On the other hand, Pato is where statues of Buddha were enshrined, which is why many scholars referred to it as a temple. However, this study proposes that Pato shall be referred to as a temple-style pagoda in a form unique to Myanmar, based on the origin of Pato, definition of pagodas, and Sarira Enrichment Record of Pato. Moreover, it seems more appropriate to name this type of structure Stupa Temple(塔殿) or Stupa Shrine(塔堂) rather than a Buddhist temple(佛殿) or Buddhist shrine(佛堂) for clear distinction. Pato, or temple-style pagodas, has a ${\acute{S}}ikhara-style$ structure at the center like Ananda Pato upon entering the Pagan (Bagan) kingdom period, on which Zedi-style structures are built. As a result of examining the integration of various Buddhist schools and religions focused on Theravada during the period of King Anawrahta and King Kyanzittha, the ${\acute{S}}ikhara-style$ structure is a symbolic representation of the fact that Theravada embraced Hinduism. The common features shared by pagodas in Myanmar are the centrality of place and the verticality of $y{\check{a}}ngti{\bar{a}}n$ (looking up to the sky) in terms of shape. All temples are placed at the most important and central space, and their forms represent strong religious $y{\check{a}}ngti{\bar{a}}n$ and verticality. These are the features that stand out most among various pagodas in Buddhist countries.

The objective of the study is to establish a BIM modeling of precast concrete(PC) shear wall with various wall-to-base connections. The family library of PC shear wall was established in BIM program using component function in a IFC(Industry foundation classes) file format and SketchUp program. From the BIM program, the amounts of concrete, reinforcing bars and steel materials as well as the interference of arranged reinforcing bars can be accurately evaluated in the PC shear walls with spliced sleeves, bolt, or welding plate connection methods. Although the additional metallic materials such as steel plates, bolts, and nuts were used in the PC shear walls with welding plate connection method, their amounts of materials, economic efficiency, and environmental impact were similar to those with spliced sleeve connection. Consequently, the bolt or welding connection is a highly applicable method as wall-to-base connection of PC shear walls, and it was a more useful method than spliced sleeve method, particularly considering the constructability.

This study examines the process of the introduction of stupa, which has originated in India, to the Xinjiang Uyghur region and the features of the stupas in the Xinjiang Uyghur region in detail. This study examines the layout of the buildings in temple compounds and the types, structural elements, and construction methods of the stupas in the Xinjiang Uyghur region in particular by looking into the content of the Da Tang Xi Yu Ji and remaining stupas, which provide examples of stupas at the time. This study finds that due to the characteristics of dry deserts, stupas in Xinjiang Uyghur region, where assimilation between Eastern and Western cultures is seen, were mostly made by pressing clay into a mold and had no interior spaces. Also, construction materials and techniques had been developed and improved in a way that enabled stupas to combat the challenging desert conditions. However, the stupas in this region differed significantly from the wooden tower-like stupas discovered in central China(zhongyuan 中原). The shape of the dome of most stupas in Xinjiang Uyghur region was chosen under the influence of the Gandharan style. Some of the stupas in the region have taken the general forms of the wooden stupas and the others have taken many forms, from cylindrical drums to towers. Also, there have been forests of stupas and stupas similar in form to chaityas and stupas of Vajrayana. Such different forms were transformed and modified through regional history and it was related to the peoples and cultures that produced and used stupas. Stupas evolved into distinct forms in Xinjiang Uyghur region in this way.
