The stiffness properties of heterogeneous concrete materials and their degradation were investigated at different-levels of observations with aids of the opportunities and limitations of multi-resolution wavelet analysis. The successive Haw transformations lead to a recursive separation of the stiffness properties and the response into coarse-and fine-scale features. In the limit, this recursive process results in a homogenization parameter which is an average measure of stiffness and strain energy capacity at the coarse scale. The basic concept of multi-resolution analysis is illustrated with one and two-dimensional model problems of a two-phase particulate composite representative of the morphology of concrete materials. The computational studies include the meso-structural features of concrete in the form of a hi-material system of aggregate particles which are immersed in a hardened cement paste taking due to account of the mismatch of the two elastic constituents.

Background: The definition of evidence-based clinical practice guidelines (CPGs) is "statements that are systematically developed to assist in the doctors' and patients' decision-making in certain situations." This study aims to establish the concept of evidence-based CPGs and investigate the development status to seek measures to apply evidence-based methods to CPG development for dental sedation in Korea. Methods: The study conducted systematic searching methods based on evidence-based CPGs. Articles published between 1995 to 2015 were searched on a Korean database and the international database PubMed. The search was based on keywords related to four subjects (dentistry, clinical practice, guideline, recommendation). Two authors independently reviewed the searched articles to determine their analysis inclusion and the convergence stages, and to arrive at a conclusion through discussion. Results: A total of 65 Korean CPGs were included. There were 51 medical guidelines, of which seven were dental and seven were Oriental medicine. Conclusions: As a basic direction for the development of evidence-based CPGs, this work suggests the following: increased awareness; consensus on the need to supply evidence-based development methods; education, computerization, and systematic observation of evidence-based CPG development methods; continuous research development and distribution of CPGs; and creation of a database for Korean clinical dentistry practice outcomes

Moment redistribution problem that reflects plasticity concept is foundation of limit state design and it has been interested to design engineers and researchers for a long time, because it enables the reasonable estimation of strength of structures through amount of reinforcement control about negative moment in support. Many researchers find that moment redistribution closely related to ductility of degree of structure and there are a lot of difficulties in achieving the reliable experimental results because of a lot of restriction of experiment. So, studies are achieved for indirect estimate methods about ductility ability of structures. Each design standards limits that the degree of redistribution of bending moment is based on the measurement of ductility of structure, and it shows conservative results. In this study, with these results, present the basic data for reasonable strength estimation methods and allowed moment redistribution of reinforced concrete continuous beams.

This study examined the awareness of the middle aged about the digital home system and well-being apartment design elements in order to suggest the design guidelines for planning of the elderly housing environment. By literature review, the concept and characteristics of the digital home system and well-being Apartment design elements were summarized the degree of satisfaction and preference of middle aged for these characteristics were investigated and analyzed. For this study, a questionnaire survey of 156 housewives living in apartment complex of Busan was carried out. The results of this study are as follows: The middle aged were generally short of recognition for digital skill and service, and also they showed positive evaluations to a few useful items of digital home system. These items belong under safety security system and interior environment control system and provided for convenient & comfortable life. Accordingly, satisfied digital home system can apply basic design element for housing for elderly. Whereas, the middle-aged were not satisfied with housework help system and cultural life system because items of these systems were not various and complicate to us. So, for the improvement of not satisfied digital home system, we needed development of digital contents and marketing & management for high accessibility and easy useability. The middle aged will concern about health & environment friendly continuously and become to stay long in their housing as the characteristics of elderly. So, It is necessary to be considered well-being apartment design elements of health & environment friendly very actively and lastingly in elderly housing environment design. Also, the awareness of middle aged for digital home system and well-being apartment design elements varied according to the background characteristics. This suggests housing environment for elderly life is considered differently as various background characteristics of middle aged.

According to continuous development of information technology, it is needed to make convergence of other disciplines such as humanities and area studies. Among convergence fields related to information technology and humanities/area studies, electronic cultural atlas represents various digitalized cultural information on electronic map using spatial data such as points, lines, and polygons through time, spatial, and subject axises. Knowledge map is to represent special academic information based on electronic cultural atlas. In details, knowledge map can provide integrated information sharing and spread because academic information associated with electronic cultural atlas and data related to per subjects, regions, and period become organically connected. Therefore, knowledge map may be utilized to promote scholastic research and diffuse research result. In this paper, we describe basic concept and composition of knowledge map and propose design method to construct knowledge map.

Among the community-based cultural facilities, public libraries are places for social and educational purpose that improve the education of the resident, the expansion of the basic cultural education, communication between the members of society, and the accumulations and preservations of the culture. Public libraries should be a local cultural facility that expresses the value of a community. This study aims to analyze the design expression of publicness in a public branch library as a community-based cultural space through the study of branch library in the U.S. This study focused on the most future-oriented and innovative Ten New Landmark Libraries in the United States selected by Library Journal magazine in 2011. Among the selected libraries, three branch libraries which belongs Arizona Maricopa County were included in the study. The results of this study are as follows. First, the sites of the branch libraries vary geographically, but the libraries increase accessibility are caused by unique appearances and design concept of intellectual interest. Second, the floor plan shows the separation of meeting rooms and faculty space from the public space and has visual and spatial open space by high ceiling of the reading room. Third, multi-functional public space for residents are meeting rooms, the external patios for reading, galleries, cafes, libraries-shops which provides a variety of cultural programs, activities, and the opportunity to socialize neighbors. Fourth, branch Libraries have unique designs that harmonizes with nearby places to reflect locality, giving the locals a sense of pride in their community. Fifth, concrete brick and metal panel were used as finishing material for the practicality of maintenance. In particular, transparent glass envelope allows the locals to stay for long time due to openness and brightness of space.

The internal streets of mixed-use commercial complexes, which are the extension of urban streets, are being changed from a mediating space aiming at movement to a staying-type space according to the change of mixed-use commercial complexes. And they function as a resting place of user with court and plaza, and act as an urban public space, and accommodate an activity arising from the gathering of many people. As a result, a role of new relaxation and community space is played in the center of the city. And the aspect of publicness is brought into relief. Hence, this study is intended to examine the characteristics that the internal streets of mixed-use commercial complexes have, and furthermore, it is intended to show the planning characteristics in the contemporary mixed-use commercial complexes. With regard to the method of research, first, space configuration and role of internal streets was examined according to the change of mixed-use commercial complexes on the basic of precedent research and literature review. And the internal streets of mixed-use commercial complexes were classified into doorway part, traffic line, and open space. And the characteristics of internal streets in the mixed-use commercial complexes through the concept of architectural 'publicness' were derived as accessibility, amenity, perceptibility, openness, connectivity and symbolism. The internal streets of mixed-use commercial complexes should be changed by the space planning to secure continuity with the city on the basis of accessibility and connectivity and to reinforce visual openness in the internal streets in order to improve amenity and perceptibility, accordingly the mixed-use commercial complexes will be also born again as symbolic public space in the city. Variously changing elements to improve publicness very importantly act on the planning of internal streets in the mixed-use commercial complexes, and therefore researches should be continuously carried out.

The purpose of this study was to find out awareness of the environment-friendly planning elements for residential unit space among practitioners. The respondents in this questionnaire survey were 140 practitioners in architecture and interior design field. The major findings of this study were as follows; most of the respondents were aware of the impact of indoor built environment on residents' wellness. In addition, the survey respondents viewed that the factors for planning environment-friendly high-rise apartments were represented by gardening and energy-saving while their perception on the concept excluded comprehensive components affecting residents' life quality. Over 50% of respondents had an experience of applying environment-friendly planning elements in their works, and high frequency appeared on the general planning elements which had been applied special awareness as pro-environmental features. The respondents considered environment-friendly planning elements as important. Specially, space planning and system were considered more likely important in interior design field. In application of environment-friendly planning elements, cost, lack of consumers' awareness of and underdevelopment of environment-friendly materials were of concern. Therefore, the consumer's cognition needs to be improved for wide application about environment-friendly planning element, and then consumers are willing to pay additional construction cost of environment-friendly apartments. At the same time, the current practice that housing developers pass the additional cost on to residents needs to be changed. Then, the quality of life in high-rise residential settings can be improved. More importantly, the exchange and development of the reliable information on environment-friendly planning elements need to be made, and technical support and long-term policy for the development are required. This research showed current status of knowledge and practice in sustainable planning of unit apartment and proved basic information for future direction.
