Variation Analysis (VA) is used to simulate final product variation, taking into consideration part manufacturing and assembly variations. In VA, all the manufacturing and assembly processes are defined at the product design stage. Process Capability Data Bases (PCDB) provide information about measured variation from previous products and processes and allow the designer to apply this to the new product. A new challenge to this traditional approach is posed by the Industry 4.0 (I4.0) revolution, where Smart Manufacturing (SM) is applied. The manufacturing intelligence and adaptability characteristics of SM make present PCDBs obsolete. Current tolerance analysis methods, which are made for discrete assembly products, are also challenged. This paper discusses the differences expected in future factories relevant to VA, and the approaches required to meet this challenge. Current processes are mapped using I4.0 philosophy and gaps are analysed for potential approaches for tolerance analysis tools. Matching points of simulation capability and I4.0 intents are identified as opportunities. Applying conditional variations, incorporating levels of adjustability, and the un-suitability of present Monte Carlo simulation due to changed mass production characteristics, are considered as major challenges. Opportunities including predicting residual stresses in the final product and linking them to product deterioration, calculating non-dimensional performances and extending simulations for process manufactured products, such as drugs, food products etc. are additional winning aspects for next generation VA tools.

When initially comparing Denmark with Korea, it would appear that the two have little in common. However, upon further investigation, one would find they are similar in that they both small Countries located outside of central continents without an abundance of natural resources. Each has also shown displayed its own successful design to the world. The unique qualities of Danish designs have both, in turn, influenced other Countries' designs, thus having a ripple effect worldwide in the design area. One may concluded that the schools educating these designers have played a role in Danish unique design success. This thesis investigates and details curriculums and goals of three furniture design departments of Universities in Denmark and, is useful for furniture department's in Korean schools who wish to have a better understanding of how Danish schools have achieved their success to date.

Bile acids are essential molecules produced by vertebrates that are involved in several physiological roles, including the uptake of nutrients. Bacterial isolates capable of producing bile acids de novo have been identified and characterized. Such isolates may provide access to novel biochemical pathways suitable for the design of microbial cell factories. Here, we further characterized the ability of Maribacter dokdonensis, Dokdonia donghaensis, and Myroides pelagicus to produce bile acids. Contrary to previous reports, we did not observe de novo production of bile acids by these isolates. Instead, we found that these isolates deconjugated the amino acid moiety of bile acids present in the growth medium used in previous reports. Through genomic analysis, we identified putative bile salt hydrolases, which could be responsible for the different bile acid modifications observed. Our results challenge the hypothesis of de novo microbial bile acid production, while further demonstrating the diverse capacity of bacteria to modify bile acids.

The aim of this paper was to compare differences and similarities of farmhouses between Denmark and Korea as a cross-cultural study. Farmhouses built during the 18th and 19th centuries in Denmark, and ones from Chosun Dynasty (AD. 1392-1910) in Korea were targets of this study. Literature study and field trips to districts and open-air museums in both countries were used. Field trips were carried out during summer of 2005 in Denmark, and fall of 2005 in Korea. Detailed comparisons focused on farmhouse plans, the use of rooms and furnishing, and building materials. As a conclusion, some differences were found between the two countries. In terms of farmhouse plans, square types with four wings, and parallel types were the most frequent forms in Denmark, while a few types, such as the "I", "L", "U" shapes and square types, were more frequently found in Korea. In Denmark, the most important room was the dwelling-room, in which daily family life took place. Every member of the family slept, ate, and worked here, and kept geese and young animals during the winter season. Therefore, this room was laid out in the center of the house. However, Anbang, the most important room in Korea, was not situated in the best part of the house. Instead, the Daechung-maru occupied the center and the best place because the daechung-maru, in which the ancestral ceremony was held, was thought of as more important than a place for live people. Also the use of rooms and furnishing was quite different between the two countries, reflecting each life style. Danish furnishings represented practical daily life, while Korean furnishings reflected more conceptual aspects. It might have resulted from Confucianism in the Chosun Dynasty, which ruled daily life and even influenced use of rooms and furnishings. In other word, philosophy influenced common peoples' daily life and living environment. With reference to building materials, there was rarely a difference between the two countries. Major materials for farmhouse were quite common, such as half-timbering wood and clay, but the difference was in bricks and roof coverings. Bricks were rarely used in Korean farmhouses, while rice-straw was rare for the roof of a Danish farmhouse. Of course, the choice of materials was strongly affected by the local surroundings and overall environment. This result can give some clues for design ideas when architects and interior designers plan housing that is adapted for local peoples. This kind of cross-cultural study can also contribute to one's understanding of foreign culture, especially in housing and culture. And, it can broaden one's insight of design ideas for designers who have to compete frequently with designers in foreign countries.

In Scandinavian countries, where the society experienced change of typical nuclear family structure and higher vocational activity rates of married women earlier than East Asian countries, cohousing scheme has been evolved as an alternative housing to reduce housework for working women, and to reduce loneliness of elderly people who stay in their own homes. They can promote active mutual relationship among residents in the community. Korean family structure has been stemmed to more like extended family, but the tendency to live independently from their married children is getting more and more common in new cohort of senior citizens who are active, healthy, economically stable and higher educated. Korea has been industrialized rather rapidly since 1970's and faces to many societal phenomena about quality of life for senior citizens. Introduction of alternative housing solution for these senior citizens is necessary in Korea. In this paper, Danish senior cohousing scheme, particularly, self-work model project is described about its design feature in accordance to site planning, common facility, and dwelling unit. Aiming to mutual support and more frequent social contacts among residents, self-work model cohousing scheme has different design concept from the service mode scheme. Information about design feature of senior cohousing was collected from the published data with drawings and from field survey to 10 exiting projects in Denmark. Of those, 5 projects were described as a case study. It, hopefully, could provide practical information for architectural design when establishment of senior cohousing schemes start in Korea in the near future.

Korea has experienced serious changes during the last several decades of industrialization. Limited land resources and excessive rural-to-urban migration inevitably resulted high-rise apartment housing development. However, apartment housing couldn't follow up social change and residents' needs. Turning into the 21st century, there are great demands for the diversification of housing style and amenity of housing, which include enhancing community lift through proper collective environment. To solve these problems, cohousing has been introduced in Scandinavian countries. A primary goal of cohousing is the desire of residents to live in a socially supportive setting. People can do housework together and also can promote active mutual relationship among residents in the community. Physical feature of cohousing, in combination with social organization factors, may serve to enhance or support the sense of community sought by residents. In this point of view, the purpose of this study is to find out the physical feature of cohousing in Denmark and Sweden. First, it is to figure out the background and development of cohousing in Denmark and Sweden. Then, by making clear physical features between similarity and difference of two countries of cohousing through case study; such as housing type, the circulation patterns, common facilities and etc. This paper could suggest a possibility of application of cohousing in Korea to present how they encourage emphasize design aspects that increase the possibilities for social contacts and the sense of community. Also, it goes on to suggest that the educational program and the support from the government.

The aim of this research is to examine patterns of design governance used by Northern European countries to respond to social crises and understand design governance as a tool for sophistication of social services and social integration. Design governance as applied in Sitra of Finland, MindLab of Denmark and the Gulliver project of Germany encourages using design methodology for analyzing and solving problems related to social phenomena based on involvement of the private, public, industrial, and academic groups. Especially, the citizens are actively involved in developing problem-solving ideas and designing new policy with other governance members, rather than simply providing information or one-time participation. In the cases discussed in this study, design governance reduce unnecessary administrative and financial consumption and inconvenience caused by complicated rules, based on field-oriented approach, regional characteristics, pluralism, and respect for diversity. Therefore, future design policy paradigm will need to evolve into concept of policy design and pluralistic monitoring centered on design governance based on participation of private sector to lead policy development, from the current system in which only few officials decide policy.

Vilhelm Wohlert is the Danish architect who designed Louisiana Museum of Modern Art near Copenhagen. Because of Louisiana Museum's popularity, Vilhelm Wohlert's name was started to be aware since 1990s. Although he is a well-known architect in Denmark, unfortunately his name is unknown in other countries. He designed various design projects from small scale furniture design to large scale museum and public projects. There are three programmatic categories in his architecture: exhibition programs including Louisiana Museum, residential program including private houses, and public programs including churches and schools. This thesis focuses on his residential design projects. Even though he designed a multi-family houses, Wohlert's house design consists of mainly one-off large private houses located in a nice natural environment. In chapter 3, the general history of his house projects was studied. Among them, the first exhibition house for Forum was explained more deeply to show Wohlert's early house design philosophy. In chapter 4, three built house projects were analyzed in detail. Analytical diagrams were used to show the key elements in the residential space. They are program composition, circulation, spatialization elements, final construction. His buildings have been compared with Alvar Aalto, Frank Lloyd Wright, and other Scandinavian architects. But there are some major differences that make Wohlert's design unique. In chapter 5, the case analysis results were summarized together to highlight the specific design characteristics found in Wohlert's residential design process. The universal spatial quality found in his residential projects can be applied in contemporary spatial designs.

Louisiana Museum of Modern Art near Copenhagen is the most visited art museum in Denmark. It was originally founded by the director of the time, Knud W. Jensen and designed by two Danish architects, Vilhelm Wohlert and J${\o}$rgen Bo. The first part of the museum was built and opened to the public in 1958. The first part consisted of just a few exhibition spaces and glass corridors. But museum has been expanded step by step into a large park-like museum throughout 40 years of time. Louisiana museum has a unique environment in which art, architecture and nature are inter-related together. There was a very clear background for this museum atmosphere that was created by Knud W. Jensen from the very beginning. He wanted to make 'a sculptural park' or 'a low pavilion in the park'. The concept of 'park' was the key element. The architects, especially Vilhelm Wohlert who studied at the western area of the United States and influenced by the bay area architecture as well as the oriental wooden structure, interacted with the director's idea fully and made an invisible architecture in which 'Experience of Space' is the most important aspect. This thesis aims to analyze several crucial spaces of the museum and to find a hidden design characteristics. Chapter 2&3 explains general backgrounds and main design philosophy. Chapter 4 studies each parts' spatial experience and design methods with 3-dimensional diagrams. Chapter 5 tries to make an overall design characteristics that underlines the whole museum environment. The significance of Louisiana museum is not only in the fact that it is the most visited, but also in the fact that the role of architecture is to make a better environment where human and art are harmonized together within nature. The utopian idea of the founder started in doubt almost 50 years ago has been already successful in this small but vibrant park.
