As interests towards health rapidly increase recently, interests and demand for hospital interior space are increasing as well. Therefore, most of today's hospitals that have been functionally designed are transforming into healing environments that consider psychological aspects, in order to assist patients forget about fear, desperation and have peace of mind. With such creation method of healing environment, natural elements can be applied to spaces in order to allow patients feel vitality, hope and adapt positive thinking, and these can eventually lead to affluent fusion of humans, nature and space. Through case analyses of how natural elements are applied to hospital's interior space, this study understands its characteristics. According to the findings, nature is largely classified into light, water, plant, stone/soil, and its application methods can be classified into center, transition, continuity, division, opening and closure. As evident from case analyses, application of natural elements to hospital's interior space promotes exchanges among patients through community formation, and achieves the effect of spatial concentration and public place. Also, ambiguity of exterior and interior boundary creates a sense of expansion and continuous effect, and can also provide a healing environment that can fully absorb natural environment open to patients. This study aims to be of service when designing hospital's interior space, with its natural element application method for healing environment research, and wishes for continuous studies on healing environments with more diverse methods.

This study is aimed at grasping how the farmhouses in Yongdong area continues to be transfigured according to the modernization and urbanization since 8.15 Liberation through the analysis of natural environment and sociocultural environment elements. The farmhouses in Yongdong area before 1960's have had a different spatial structure from those of the other areas because of the characteristics of the climatic, regional, geographic and sociocultural environment elements. The roof improvement promoting law after 1967, the Saemaul Movement since 1971 and the standard drawing of farmhouse after 1972 are transfigured the rural villages, but they were turned up the limitations of their exploits because of the lack of cognition about environment elements. Recently there were appeared the farmhouses which were reflected farmer's decisions in construction after 1980's because former farmhouses were not give consideration to environment elements.

The purpose of this study is to suggest a direction for eco-friendly healing space design for healthcare facilities in the future. Theoretical review and case study on the concept of sustainable design, spatial expression and behavioral affordance were used as research method. Through these reviews, the 3 elements of the total healing environment -physical, psychological and social- have correspondence with elements of spatial expression; Refuge, Flow, Prospect and Void. And these are related to the eight kinds of Behavioral affordance which are subdivided into WORK&STUDY, REST, CIRCULATION, VISUAL SEQUENCE, SOCIAL EXCHANGE, REFRESHMENT, COMMUNITY and MEDITATION. And the concept of sustainable design consists of 6 principles ; Natural system, People, Place, The cycle of life, Energy & natural resources and Process. Through correlation analysis of behavioral affordance and 6 principles, the result of this study presents that the physical elements of the total healing space was mainly associated with the principles of people, place and the cycle of life. Psychological element was related to principle of natural system, human, place and process. And social element was associated with the principles of human, place and process. According to this analysis, the case study of four low-rise eco-friendly medical facilities was undertaken. Sustainability was evaluated in total healing environmental through this case study.

The current investigation is the first endeavor to apply the full layerwise finite element method (FEM) in free vibration analysis of functionally graded (FG) composite plates reinforced with graphene nanoplatelets (GPLs) in thermal environment. Unlike the equivalent single-layer (ESL) theories, the layerwise FEM focuses on all three-dimensional (3D) effects. The GPLs weight fraction is presumed invariable in each layer but varies through the plate thickness in a layerwise model. The modified Halpin-Tsai model is employed to acquire the effective Young's modulus. The rule of mixtures is applied to specify the effective Poisson's ratio and mass density. First, the current method is validated by comparing the numerical results with those stated in the available works. Next, a thorough numerical study is performed to examine the influence of various factors involving the pattern of distribution, weight fraction, geometry, and size of GPLs, together with the thickness-to-span ratio, thermal environment, and boundary conditions of the plate, on its free vibration behaviors. Numerical results demonstrate that employing a small percentage of GPL as reinforcement considerably grows the natural frequencies of the pure epoxy. Also, distributing more square-shaped GPLs, involving a smaller amount of graphene layers, and vicinity to the upper and lower surfaces make it the most efficient method to enhance the free vibration behaviors of the plate.

In this study we analyzed and interpreted the phenomenologlcal characteristics and meanings of water space in religious architecture through field studies and phenomenologlcal approaches, focusing on the religious architecture Introducing water space in contemporary architecture. The phenomenological experience elements of the research ate light, time, place and context. As the results of this study, first, light as a phenomenological element not only induces a contrast and change between light and the shadow in architectural space and various changes of light in inner space, but also operates as an element which expresses building features outward with time. Second, time as a phenomenological perception experience makes us feel changes of the environment and physical properties and experience space visually and physically. The continuity of time shows the change of a day, night and daytime and seasons. Third, water space makes the sense of place more remarkable, connected closely with surrounding nature In outer space, and creates a new space. Fourth, water space is a contextual element which harmonizes with surrounding environment by connecting surrounding natural environment with architectural space. Fifth, water space in religious architecture is a symbolic and central element, and emphasizes the atmosphere of architectural space. In addition, it makes the people who experience water space perceive the place by triggering sensitive response.

This study had the purpose to restore imaginary environment involved to symbolic thinking system of Eastern culture discontinued by scientific and reasonable rationalism of Western. To restore imaginary environment, this study selected example places such as Seoul, Beijing, Kyoto which were ancient cities of Korea, China, Japan each and used hermeneutics and phenomenological access method to draw out the element of imaginary environment by analyzing historical and cultural view of example cities. Through comparison and re-interpretation of historical and cultural view of three countries[Korea, China, Japan] in Northeast Asia, as the result of drawing imaginary environment involved within it, it was structured that the spirit and the factor of natural environment of places involved to each cities were reflected as the factor of civilized environment, organized that each element was united, and more sanctified the spirit of place step by step. This study has the meaning as first trial which comparatively analyzed city spaces of existent place of human life by new concept called imaginary environment. It may has the meaning that verifying the universality of imaginary environment involved to historical and cultural view of three Northeast Asian countries, however, there was limitation to examine specificity up to detailed elements of each city.
