This paper aims at finding some lessons applicable to successful implementation of 'The 3D Printing R/D Project' through both examining the process of adopting overseas industrialized housing production technological knowhow by home builders during the 1970's~1980's period and thereafter until now the various efforts to adjust the technologies efficiently to the Korea's unique situation. Some meaningful lessons can be summarized as follows; I) Deep understanding of 3DP technological know-why along with its inheritance, II) Readjusting of R/D period and goals(cf. Global leader Winsun's 15 years experiment), III) Restructuring for more collaborative R/D B&E system among participating researchers IV) Fostering 3DP expert-engineers and technicians from the early stage, V) Clearing legal barriers in users' adopting 3DP methods necessary, VI) Development of appropriate building material besides concrete. Therefore, it is highly recommended that the above-mentioned 6 lessons positively accepted and applied to the Research Implementation Plan in due course, especially by KICT consortium and KAIA under the guidance of Ministry of Land, Infrastructure and Transport.

Recently, shipyards are making many efforts to reduce the number of the mounted blocks by increasing the block size. This is to improve productivity and reduce related costs by minimizing block movement and shortening the building period. However, as the blocks become larger, the weight increases considerably. If the target block has a damage due to an unexpected accident during block lifting, it may seriously cause a problem of the reusability of the block. In this study, a large-sized block of the offshore structure weighing 480 tons was lifting with a total of seven sling belts, and one sling belt was broken while it was moving, resulting in a situation in which a part of the edge of the block collided with the ground. The aim of this paper is to verify the structural integrity of the block that directly collides with the ground in the form of free fall due to the sling breakage. Considering that the hook loads acting on several sling belts holding the block are redistributed when a sling belt is broken, the hook loads were recalculated at the angle just before the sling breakage. These loads were used to check the safety of the sling belts. In addition, FE analysis was performed by calculating the amount of impact from the free fall condition, obtaining the impact area by using Hertz's contact theory, and then applying the impact load to the area.

Basic concept of this study is that architectural form as a material at present has meaning for the dweller's life on the past historical plane. Main method to recover history is ethnographic interview to dwellers. Secondary method is to analyze ancestors' writings, buildings in the background of the family photos, and past drawings and then to relate them with architectural form at present. Taxonomy is a starting point: general name of the building by outside researcher is quite different from it by inside dwellers. 'Haengrang-chae', servant quarter, has never been used for servants. Function of the haengrang went outside thatched houses at the front village. Firsthand observation or simple analyses as results of several precedent research are reexamined and criticized through this study. The mansion has moaning when we synthesize with the site location based on farming land and tenant farmer, and decline of the Kyongpo Lake. Territoriality of the mansion is reinterpreted to 'In-Out Structure' by Yin-Yang thinking, Dwellers extend buildings gradually to outside village, surrounding rear hills, the lake, DongHae Sea, and finally goes to imaginative Taoist heaven beyond real nature through the literary life. Confucius principle, known to govern upper class house at Yi Dynasty also affect general composition of the buildings: perpetuation of the family by ancestor worship, elder dominance and male dominance, fraternity love in the extended family, charity display by reception of guests, Taoist scholarly life harmonized with nature. However, the study of the particular life and usage of the dwellers reinforces or corrects general supposition of precedent researches. Unique shape of the house has been formed by convenience of the dwellers' life style, early modernized free thought over the rigid Confucius design principle, and female power in male dominant society.

'Healthy Japan 21' is a new health policy that has been proposed for the 21st century: it embodies a totally new concept for its viewpoints and methods. To start with, for its goal, the focus is placed on the 'quality of life' or a life that is free of diseases, rather than mere prolongation of life. For its doctrine, the emphasis has shifted dramatically from improving the health of the entire population(the traditional approach for health improvement) to 'achieving an ideal health status for each individual. The ultimate aged society that arrives first in Japan is a society in its ultimate form for human being. Why did Japan become westernized, giving up her traditional culture? Why did she go through industrialization, sacrificing her nature? And why does she try so hard to industrialize the developing countries? These efforts are all preparation for the arrival of a ultimate aged society. During the 20th century, we believed in unlimited possibilities and expanded our social frontier. In the 21st century, on the other hand, a super-aged society(the ultimate society), a glimpse of which we have witnessed from time to time, will descend on us sooner or later. It is expected to arrive first in Japan. 'Healthy Japan 21' is intended to prepare for the arrival of the hitherto unheard of super-aged society by building the physiological basis of people. This policy is social experimentation on an immense social scale, in which questions are posed on the understanding of health, the relationship between individuals and society, the relationship between administration and citizens, the manner by which central and local governments operate, and the new relationship between prevention and therapy, 'Healthy Japan 21' may be summarized as an experiment on a huge scale directed to the ultimate form of human society, in which Japan and each of her citizens play a role and set an example for the rest of the world. Even just by considering various approaches newly suggested for this venture, one may be convinced that it is a policy with features suitable for a country that has already achieved the world's highest longevity.

The purpose of this thesis is to understand the shape of The Sijeon (Licensed-Markets) established around the Jongno and Namdaemun-ro Avenues in Hanyang during the Joseon Dynasty in the 19th and 20th centuries and then to examine the relationship with the urban structures of Hanyang City. By investigating the excavation results of the Cheongjin and Gongpyeong areas, drawings, photos, and documentary records related to the city, this study classified the building types in the Jonggak area. As a result, since the 19th century, the basic form of Sijeon with 2 Gan(間, bay) in the front facade and 3 Gan(間) on the side, in other words, 5M in the front and 8M in the side was arranged in parallel, and it was a type with a corridor-type courtyard inside. The inner sides of Jongno Avenue had an atypical flat shape that suited the more free lot, and a courtyard-type plan with a single entrance was also confirmed in the one or two Bang(房, district). This study reflected the operation method of the Sijeon buildings b between the one unit and the other units, which affected the internal spatial structures, and it found that the size and style of the Sijeon buildings were closely relevant to the size of the lots near Jongno Avenue.

During the boom of museum building in the 1970s-80s two museum wee erected in Germany. They are James Stirling's Neue Stattsgalerie Stuttgart and hans Hollein's Stadtisches Museum Abteiberg Monchengladbach, These two museums share the folowing point of similarity : Stirling's Neue Stattsgalerie Stuttgart and Hollein's Staditisches Museum Abetiberg Monchenbladbach both manifest the conditions of the times in light of their respective cities' local characters and historical contexts without being bound to traditional formality. Stirling and Hollein attempted to grasp the meaning of the 기nuseum as a city in miniature." Taking into account the t two museums’s territorial characteristics of being situated on a slope, both Stirling and Hollein made the walker to pass t through their building complex and introduced the concept of a public square within them. As a result, the museums are not j just two large buildings but are architecture composed of a collage of various structures. S Stirling’s architecture employs the method of attaching additional elements on top of basic constituents, which is suggestive '||'&'||'#61551; of the historical fragment from Shinkel's Altes Museum. On the other hand, Hollein applies a collage-style method as if he w were doing urban planning, maintaining the distinctiveness of each of the various forms and materials of buildings. T The object style buildings of the two museums actively demonstrate the contrast of double meaning to represent the a ambiguous and multifarious characteristics of the modern times. Stirling explores the theme of opposition and coexistence in h his Neue Stattsgalerie Stuttgart by placing a series of opposing concepts, such as the past and present and histor${\gamma}$ and t technology, in one space. Thereby, the contradiction and its appeal are manifested. Hollein made use of the visual illusion and c contradiction in alluding to the irony of the modern reality induced by nature and culture and history and technology. F For the above reasons and methods, James Stirling ’ s Neue Stattsgalerie Stuttgart allowed the penetration of art into daily l life and became the general public’s favored museum for its free and unrestrained environment. Likewise, Hans Hollein’s S Stadtisches Museum Abteiberg Moncbengladbach contribute to the development of museum function as it an expression of art i in the form of a complex piece of scupture on its own.ts own.

First of all, the multi-story Housing applying resident's participation in europe was classified by the menu selection method, the two-step supply method and the cooperative method. And then I analyzed flexible unit plan of cases for deriving the planning methode and the characteristics of flexibility. First, I analyzed the area and form of the unit plan, structure and Installation, fixed and variable elements to derive the planning method. The area of units are distributed from a minimum of $35m^2$ to a maximum of $150m^2$, and many of the unit planes have a narrow front and a deep depth. The structure is a long-span wall-structure or a skeleton structure, and is designed without any columns and bearing walls in the interior space for flexibility in spatial composition. The vertical shafts are located in the center of the unit in a box-form or in the corner at the unit dividing wall for free placement of interior wall. Fixed elements are framework and facility systems. Most of the future residents in the two-steps supply method and the cooperative method were able to freely design the internal space within the zoning concept proposed by the architect and change the location of the facade element within module system proposed by the architect. Second, the characteristics of the flexibility applied to the unit plan were divided in integrated flexibility, functional flexibility, construction flexibility, and supply flexibility. The integrated flexibility enables residents to give the variable space combination based on the complex structure of the inner space for providing various living experiences. Regarding functional flexibility, the three-dimensional spatial structure with neutral space has multi-functionality according to the needs of residents and easily accepts mixing of hybrid programs such as work and residence. Constructive flexibility allows residents to create identity by freely planning interior space and changing the size or location of facade components in a determined system of architects. Finally, various types of size and space composition are proposed and realized in the whole building applying menu selection method, so that flexibility in the offer can accommodate and integrate various types of living.
