본 연구는 옥외공간 설계변화에 대해 거주민들은 옥외공간에 대해서 어떤 인식을 가지고 있는지 조사하고자 옥외공간을 녹지공간, 놀이 및 운동 관련 공간, 보행공간, 휴식 및 조경시설 공간으로 분류하고 이에 대해 각각의 만족도와 개선사항을 단지규모별로 분석하였다. 분석결과에 따르면 단지내 특색있는 공간이 어딘지에 대한 질문에 단지의 규모가 클수록 녹지공간과 운동 및 놀이공간, 휴식 및 조경시설공간이 비슷한 비율로 응답된 반면, 모든 단지의 응답자들은 단지내 가장 부족한 공간으로 운동 및 놀이공간을 생각하고 있는 것으로 나타났다. 단지규모에 따른 아파트 단지의 옥외공간에 대한 세부공간별 평가결과를 살펴보면 대단지일수록 옥외공간 설계시 좀 더 많은 설계 항목이 도입되고 운동 및 놀이공간 및 휴게공간 등에 대한 강조가 이루어지고 있는 현실과 달리 주민들의 평가는 이와 상반된 결과를 보이고 있는 것으로 나타났다. 이는 단지규모가 클수록 옥외공간에 대한 이용객이 증가하여 이에 대한 수요가 증가하고 다양화되는데 비해 단지설계는 이를 뒷받침하지 못하고 있음을 보여주는 결과라 할 수 있을 것이다.

Architectural & Interior design communication is a process of exchanging information between architects and other professionals, clients, and prospectus users, and a design medium is a means of communication. Using non-immersive, conventional media, it is challenging for architects communicate physical details and users' activities in not yet built three-dimensional buildings to others. Recent advances online, Multi-User Virtual Environments (MUVEs) allow architects and other professionals to experience a virtually constructed building together using anthropomorphic avatars. In addition, MUVEs also enable them to be aware of the presence and activity of each other. Previous studies suggest that the aforementioned characteristics of MUVEs may facilitate communication between architects and others. But these are focused on communication in controlled experimental conditions. This paper discusses the ways in which MUVEs are applied for authentic and long-term collaboration, design studio, and cultural heritage reconstruction projects, produced by digital design group at the UC Berkeley and the Technion-Israel Institute of Technology, and analyzes the influences of MUVEs on those projects. MUVEs helped more precise communication between architects, electronic engineers, and medical staffs, who are collaborating for developing pioneering technology for hospitals. In design studios, MUVEs allowed students to experience other students' design outputs, and thus helped them share ideas mutually. In addition, in cultural heritage reconstruction projects, MUVEs were used for communicating with historians and residents in order to collect evidence. Based on this study, we propose that MUVEs have strong potential for enhancing the communication between architects and other professionals.

Two dimensional numerical models and physical models have been developed to study the highly nonlinear interactions between waves and breakwaters, but several of these models consider the effects of the structural dynamic responses and the shape of the breakwater axis on the wave pressures. In this study, a multi-material Arbitrary Lagrangian Eulerian (ALE) method is developed to simulate the nonlinear interactions between nonlinear waves and elastic seawalls on a coastal rubble mound breakwater, and is validated experimentally. In the experiment, a solitary wave is generated and used with a physical breakwater model. The wave impact is validated computationally using a breakwater - flume coupling model that replicates the physical model. The computational results, including those for the wave pressure and the water-on-deck, are in good agreement with the experimental results. A local breakwater model is used to discuss the effects of the structural dynamic response and different design parameters of the breakwater on wave loads, together with pressure distribution up the seawall. A large-scale breakwater model is used to numerically study the large-scale wave impact problem and the horizontal distribution of the wave pressures on the seawalls.

Korea is experiencing unprecedented destruction of communities and crisis of mental health represented by top suicide rate among OECD countries. Its causes are manifold of various factors. One of them is lack of social support and broken communities that are closely related to social capital that is linked to other health indicators such as mortality rates. This studies looks for ways to improve social capital through spatial structure and features especially social capital related to neighborhood. Researchers conducted research literature review and observation on physical features of neighborhood streets and alleys. Review of studies show housing types can affect social capital level. High-rise apartments are related with lower neighborhood related social capital compared to single homes and low-rise multi-housing. Studies that mainly examined the physical features such as street layout showed that social encounters happened around local stores and crossings of small roads. Researchers identified actual streets that are more likely to be related with social activities in the neighborhood. Those streets were with physical elements that helped social exchange such as narrower streets, exposed stairs, street furniture of residents, parks, crossing of streets while other streets were with wider and easier access of cars.

It is common that most countries focus on the development of their capital cities. As a result, other areas do not develop as well as capital cities. Some areas even develop into a kind of distressed community. This leads to the outflow of population and also difficulties for remaining people in these areas. Under such social background, international marriages are on the increase in rural areas and small and medium-sized cities, causing many problems in connection with that. Many researches on multi-cultural families had been conducted recently, but most of them approached their studies from the viewpoint of social welfare. The physical, economical and cultural environments of multi-cultural families are closely connected to each other. Therefore it is necessary to study these families from a holistic point of view. Therefore the purpose of the research is to study the living conditions and the potential needs of married female immigrants in an in-depth and holistic way. The direction of residential planning for multi-families is also provided. To do that, there are three stages of the research which are theoretical review, preliminary survey and main survey. Methods of literature review, workshop, and questionnaire are used. Based on the results of the research, recommendations for the direction of multi-cultural families residential planning are provided. Physically, living-room, bedroom, kitchen and toilet should be adjusted based on their needs. Socially, the feelings of alienation and exclusion should be reduced for married female immigrants. Economically, it is necessary to find a way to make sure that the second generations of multi-cultural families do not inherit poverty from their parents. Culturally, it is important to consider the different needs of immigrants and to embrace their own culture.

The needs of collaboration among design participants spread in different locations is emphasized in the early design stage in order to not only save time and provide places to meet and talk, but also to save cost for those events as well: This is being realized by the Internet, which helps support a networked, integrated real-time multi-user environment. As the base for collaboration activities moves from physical places to cyberspace, the methods of connecting every participant by means of a computer technology have been desired and considered. This study aims at investigating today's collaboration technology in the architectural design process, especially focused on the early stages, in terms of temporal dimensions. In addition, major concepts for and previous efforts and tools of collaborative design have been examined, and a specific recommendation has been proposed for future development of collaborative architectural design systems: That is distributed collaboration, which is accessible and comprehensible to all the professionals in the building design team, which not only allows the sharing of information but also the sharing of understanding, and which facilitates the development of design tools for different aspects of the envisioned collaborative design environment.
