This paper is one of the types of 'sharing economy', a social economic model that borrows and shares things, spaces, and services from the development of the 4th Industrial Revolution. Through sharing of empty space and time in the city, I would like to suggest a way to reduce the closure of small business owners in order to create jobs, which is one of urban problems in the community. We also build a platform that utilizes the free time and space of buildings through space sharing, one of the types of sharing economy, and provides education programs for start-up education, promotion, marketing, and consulting by matching small business owners with building owners. Therefore, in this paper, by sharing the space and time, the landlord and the small business can share the profits of the small business by reducing the business owner's closure and the job creation plan. Coaching urban regeneration was proposed.

In the fields of plant layout optimization, the main goal is to minimize the construction cost including pipelines as satisfying all constraints such as safety and operating issues. However, what is the lacking of considerations in previous researches is to consider proper safety and maintenance spaces for a complex plant. Based on the mathematical programming, MILP(Mixed Integer Linear Programming) problems including various constraints can be formulated to find the optimal solution which is to achieve the best economic benefits. The objective function of this problem is the sum of piping cost, pumping cost and area cost. In general, many conventional optimization solvers are used to find a MILP problem. However, it is really hard to solve this problem due to complex inequality and equality constraints, since it is impossible to use the derivatives of objective functions and constraints. To resolve this problem, the PSO (Particle Swarm Optimization), which is one of the representative sampling approaches and does not need to use derivatives of equations, is employed to find the optimal solution considering various complex constraints in this study. The EO (Ethylene Oxide) plant is tested to verify the efficacy of the proposed method.

This paper presents free vibration analysis method using the characteristics of the rotationally periodic structures and includes the analysis results of a tire as an example. The normal modes of the rotationally periodic structures are the kind of standing waves, so all sectors have the same deflection shapes, and only different phases. This property makes it possible to derive the analysis method called sector method. The sector method can give the accurate natural frequencies and the corresponding mode shapes of the rotationally periodic structure with information of only one sector. When the free vibration analysis is performed to find the dynamic characteristics of the rotationally periodic structure by using the sector method, the computer memory spaces and the CPU times can be saved. We obtained much economic benefits by using the sector method in the analysis of dynamic characteristics of a tire made of non-linear materials.

As cities face increasing problems such as aging, environmental pollution and growth limits, we have been trying to incorporate sustainability into urban planning and related policies. However, it is very difficult to generate a 'sustainable spatial plans' because there are trade-offs among environmental, society, and economic values. This is a kind of non-linear problem, and has limitations to be solved by existing qualitative expert knowledge. Many researches from abroad have used the meta heuristic optimization algorithms such as Genetic Algorithms(GAs), Simulated Annealing(SA), Ant Colony Optimization(ACO) and so on to synthesize competing values in spaces. GAs is the most frequently applied theory and have been known to produce 'good-enough plans' in a reasonable time. Therefore we collected the research on 'spatial optimization model based GAs' and analyzed in terms of 'study area', 'optimization objective', 'fitness function', and 'effectiveness/efficiency'. We expect the results of this study can suggest that 'what problems the spatial optimization model can be applied to' and 'linkage possibility with existing planning methodology'.

Although Jaesil are historical products which is related to our traditional culture, they have not been studied extensively. This study deals with the location and the spacial compositional characteristics of Jaesil, a traditional building special functions in culture. The summarized results are as follows : 1) Jaesil wee constructed in 15c~20c. Jaesil in Kyungpook province were built by the intelligent classes in 17c~18c, while Jaesil in Kyungnam province were built by the rich farmer classes with economic power in 19c~20c. 2) The functions of Jaesil were the following : It was used for the purpose of worship, school, temple. The main function in Kyungpook province was worship, while the main functions in Kyungnam province were worship and school. 3) The relationship between Jaesil and villages were as follows : Jaesil in Kyungpook were located in the mountains apart from villages and their main elements of landscape were valleys or rivers . While Jaesil in Kyungnam was located in the residental spaces and their main elements of landscape were an artificial pond or no water landscape. 4) The plane form of Jaesil, Which was constructed specially 'The ㅁtype' of Jaesil were common in Kyungpook province and tis type expresses the enclosure and centrifugal force. While 'The 一type and 二type' were common in Kyungnam, and this types expresses the poenness and practicality.

To establish a new creative economy, the worldwide efforts have been made to wriggle out the old economic paradigm after the financial crisis of 2008. When it comes to the limitation of the viability. the start up companies have a high risk of failure. Therefore business incubator (BI) should carry out the role to improve their viability. As for the maximization of the effect on the business incubating services as move in companies, it is important for BI to increase the level of business incubating services by the systemic and scientific measurement. This study showed that the quality of the BI center services was measured by Kano analysis and the previous research as follows. First, BI quality attribute by Timko's customer satisfaction came out into the attractive qualities on the 14 items that amount to the 70% of 20 business incubating services items. It is desirable to perform the strategy for the satisfaction. Secondly, basic business incubating services were interpreted as the one-dimensional quality like incubating spaces, parking facilities, security facilities, industry technology development funds, and incubating managers. Finally, training and educational service was recognized as indifferent quality. Futhermore, the improvement and the limitation of this study as well as the interpretation of analysis results are also provided.

Current criticism regarding the "uniformity" of Korean apartments has shown not only tendencies of emotional and unscholarly criticism, but also lack of academic discourse. They tend to stay at the common-sense level and be quite subjective without supporting facts. This research began with questioning the phenomenon of seeing Korean apartments as an object of negative criticism. The research questions for this study are: 1. Of the living space of so-called apartment houses, what elements should be called uniform?; 2. How should the implications of the findings be interpreted? In this context, this study aims to reinterpret criticisms on the uniformity of apartments from a new point of view. First, literature review is done to examine characteristics of Korean apartments in the social-cultural, economic, and physical contexts. Next, existing non-academic, abstract criticisms are classified into three trends, to show that the way of understanding architectural spaces by those criticisms are limited and weighted towards visual perceptions focused only on the shape of architectural structures. Finally, it is argued that the viewpoints of space and residents' experience should be treated as important for the reinterpretation of criticisms on the uniformity. This is validated through presenting relevant cases such as changes of space uses, diversified lifestyles being accepted, and the expansion of living space.

Hanok is Korea's traditional housing, which is build detached unit. Most of the People who live in the environment of residential high-rise apartments likes new residential environment, and pursue eco-friendly homes, health homes, especially traditional Hanok was reassure potential. In urban context, resident think more compact land use in Hanok also, because Hanok is dissatified in compact land use, and it should be build as more economic aspect. The purpose of this study is to propose a typology which traditional Hanok also can be build higher land use and traditional values as a modern housing type; First of all, clustered Hanok is formed by traditional houses and interior spaces in modern house., and its types are configured by lifestyle of modern and image element of traditional Hanok. This kinds of clustering Hanok can be seen from historical city, but the trends is a minority of the housing type and form. Now, the modern clustering Hanok, even though handful of cases, appears as sustainable housing type, its possibilities as a new housing should be more detailed researches. A elements of Modern cluster Hanok discused in layout, plan, envelopment of house, structure, roofs, and the coordination of the element can be so much diverse.
