Passing 26 years from 1970 when the first satellite was launched into the orbit, Japan developed and successfully launched H-II from Tanegashima Space Center in 1994. During those period, Japanese space policy has experienced a big shake from independent development to technology import from the US, and back again to independent development. In general, the H-II rocket which was manufactured by 100% domestic technology, brings Japan from the old era (experimental stage) to the new era (practical use stage). Fundamental Policy of Japan's Space Activities, which decides such policy as mentioned, was revised in January, 1996 this year after an interval of 7 years. This revised outline confirms the result of Japanese space technology until present and identifies the future direction and framework of her space activities for a period of coming ten years on the basis of a ong-term perspective towards the 21st century. However, when comparing with the last Fundamental Policy in 1989, there seems no big change in it, and a long-term perspective is also not seen there. The description varies on some important points in international space law, like international cooperation, protection of environment, commercial use, etc. In addition, the immaturity as well as the necessity of broader discussion are felt because neither this Fundamental Policy nor The National Defense Program Outline treated any national and international security matters concerning outer space. Considering the present time when Japan enters into the practical use of outer space, such as application, commercial use and launching service, etc, it is doubtful whether new Fundamental Policy was properly planned or not. It seems necessary to use several measures by which the public opinion, opinions from industry and debate on the security are reflected in the policy making.

Recently in South Korea, family-friendly living environment in resident communities have emerged as an important issue in addressing problems created by personalized and fragmented family in urban areas. Since their foundation in 2005, Healthy Family Support Centers provided a variety of community activities for both parents and children through the Co-Child Care Sharing Programs. That being said, it is certain that the Healthy Family Support Centers play a central role in making a family-friendly environment. This study surveyed the physical environment of the co-child care sharing space and suggested further improvement. The content of this survey represents the characteristics of co-child care sharing space in Incheon such as operation status, physical space, prepared facilities, and preference for facilities. This study also explored the field of two co-child sharing spaces (Bupyung-gu and Seo-gu) as an example case. The subject of this study was 14 co-child sharing spaces of nine Healthy Family Support Centers in Incheon investigated from July 2014 to October 2014. This study indicated three results: first, the size of the co-child care spaces, their composition and facilities are very different from each center and require standards and guidelines for the co-child sharing space in regards to physical space, composition, and facilities. Second, co-child sharing space should be provided with individual special programs and diversified activities in addition to playing activities. Third, many healthy family support centers operate over two co-child sharing spaces along with an out-located co-child sharing space that require mutual organizing and operational networking between each co-child sharing space to effectively share programs.

Recently, for the purpose of choosing reasonable and economical construction, the decision making analyses, such as VE (Value Engineering) and LCC (Life Cycle Cost), are generally performed. But, these methods have some limitations for the application to subway tunnel construction method. So, the AHP (Analytical Hierarchy Process) analysis is applied to determine relative importance for obtaining objectivity in quantitative analysis. And, the LCSC (Life Cycle Social Cost) method is developed to account for the social loss and risk by tunnel construction. From the case of the subway ${\bigcirc}{\bigcirc}$ lot, those methods are very useful to decision making analysis. And, in that case, both quantitative and quantitative analysis appraisement, the drilling and blasting method is evaluated useful alternative proposal in comparing with the cut and cover method.

The value and functionality of boundary barriers in rural villages have been neglected in the aspects as the buffer zone(boundary barrier) that links between the inside space(housing site) and the outside space(road). On this understanding, this study evaluated conservation value, economical efficiency and durability by the types and materials of the boundary barriers in rural village through Multi-attribute Decision Making. By applying to the current situations of boundary barriers on total 21 case study villages, each factor value was measured. And using Matrix Analysis Technique, the boundary barriers are classified into 4 types and the improvement ways for each type were proposed. As a result, the durability of boundary barriers in rural villages showed similarity value(more than 0.85 out of 1). But economical efficiency of those was low(less than 0.5 out of 1) and those functionalities were very lacking(about 0.3 out of 1). In the conclusion, the maintenance of boundary barriers in rural villages requires the policy that is able to complement conservation value and economical efficiency and is proper to the characteristic of each village. These renewable policies would contribute to the increase of the value of rural amenity as well as creation of economical and social value.

In this paper, we present the area-based Q-learning to search a target object using multiple robot. To search the target in Markovian space, the robots should recognize their surrounding at where they are located and generate some rules to act upon by themselves. Under area-based Q-learning, a robot, first of all, obtains 6-distances from itself to environment by infrared sensor which are hexagonally allocated around itself. Second, it calculates 6-areas with those distances then take an action, i.e., turn and move toward where the widest space will be guaranteed. After the action is taken, the value of Q will be updated by relative formula at the state. We set up an experimental environment with five small mobile robots, obstacles, and a target object, and tried to search for a target object while navigating in a unknown hallway where some obstacles were placed. In the end of this paper, we presents the results of three algorithms - a random search, area-based action making (ABAM), and hexagonal area-based Q-teaming.

Recent advancement in ICT and IT infrastructure drives the construction industry towards a IT-based industry. Accordingly, the importance of the planning phase of a project is significantly highlighted due to recent large-scale national development projects such as U-city and multifunctional administration city. various development and studies are conducted on the convergence of 3D CAD and GIS in order to support the decision making by simulation of each phase of construction prior to the actual construction of a building. However there has been limits to the implementation of the IT technology in the planning phase due to its characteristics such as high reliability on the experts knowledge and the compliance of the administration work. In this study, a trendy issue of the convergence of the GIS technology with the 3D CAD design data is suggested to improve the efficiency of a decision support in the planning phase.

Schools have developed together with local communities, as leading public buildings that represent local communities. Most elementary schools are located in walking distance, so that makes it possible to maintain close relationships with local residents. This study examine outside space where the school buildings are restructured for new images through public park project. The results of this research as follows. 1st, Public park project of school facilities is charge of key role to improve urban image. 2nd, Public park project of school facilities promote environmental, social and educational participation of school members. 3rd, We need to develop a outside space plan and to gather diverse opinions before we start on the Public park project of school facilities. 4th, It is important to maintain the space desirable through sharing of roles by members of schools and local communities. Public park project of school facilities has to be the center of participation, process, commune and practical use.

20th century was the age of Modernism which was based on rational side of human mind. However, with the fall of Modernism, also came the fall of rationalism's dictatorship. Now, we see the pursuit and quest of irrational thinking as a new possibility of human expression which actually was already begun by Dada and Surrealism in early 20th century. It was facilitated by re-evaluation of Freud's psychoanalytic theory at the end of 20th century. This paper researches psychoanalytic approach applied to the analyses of unconscious human desires in art and design, especially its application to contemporary space design. These designs represent, without making any ethical evaluation, the fact that those unconscious desires are part of inborn human nature and the fact that 21st century is heading toward open society which embraces diverse values and possibilities. By analyzing irrational tendencies in contemporary space designs, this paper aims at proving the meaning and value for one of new directions in 21st century space design. First chapter is an introduction. Second chapter studies Freud's psychoanalytic theory. Third chapter examines the psychoanalytic methodologies with which unconscious desires are expressed in art and design. Fourth chapter classifies the types of subconscious desires expressed in contemporary space designs and analyzes their case studies. Fifth chapter is the conclusion.

Purpose: The purpose of this study is to propose a methodology for the urban regeneration by constructing contemporary publicness. Beginning with researching on the theoretical fundamentals about publicness and urban regeneration, it introduces the examples to analyze the spatial characteristics of publicness in the contemporary urban architecture, and finally simulates a model for the formation of space through a real work. Method: The study is partially based on the Executive Urban Project, 'Masterplan to make New Taekrigi : Gosan', which was planned in 2013 to suggest a strategic settlement layout for urban regeneration. Making architectural ideas permeated into the model of urban planing, throughout the design process of initially pursued concepts to the design development stage, we could encounter a new type of formation of urban space, coinciding with the historical, cultural ecological contexts. Result: The expected result of the study intends to enhance the relationship between the formation of public space and urban structure, also ultimately to produce a urban system as 'space generator' to fulfill the social needs and its requirements.

Purpose: This study is to propose a methodology for the formation of space according to the integration of structural concept and architectural concerns in the contemporary era. Beginning with researching on the theoretical fundamentals about surface-structure, it introduces several architectural examples to analyze its own structural form and spatial characteristics, and finally simulates a model for the formation of space through a real work. Method: The study is partially based on the Executive Architectural Project for 'Village of Spring' in Seocheon, which was planned in 2008 to suggest a strategic settlement layout for urban regeneration, and completed in 2012. Making architectural vocabularies permeated into surface-structure, throughout the design process of initially pursued concepts to the design development stage, we could encounter a new type of innovative space formation. It shows that the structure is one of most useful means for the realization of architectural concepts, and a design itself. Result: The expected result of the study intends to enhance the relationship between spatial formation and surface-structure, also ultimately to produce a structural system as 'space generator' to fulfill the social needs and its requirements.
