Disproportionate collapse triggered by local structural failure may cause huge casualties and economic losses, being one of the most critical civil engineering incidents. It is generally recognized that ensuring robustness of a structure, defined as its insensitivity to local failure, is the most acceptable and effective method to arrest disproportionate collapse. To date, the concept of robustness in its definition and quantification is still an issue of controversy. This paper presents a detailed review on about 50 quantitative measures of robustness for building structures, being classified into structural attribute-based and structural performance-based measures (deterministic and probabilistic). The definition of robustness is first described and distinguished from that of collapse resistance, vulnerability and redundancy. The review shows that deterministic measures predominate in quantifying structural robustness by comparing the structural responses of an intact and damaged structure. The attribute-based measures based on structural topology and stiffness are only applicable to elastic state of simple structural forms while the probabilistic measures receive growing interest by accounting for uncertainties in abnormal events, local failure, structural system and failure-induced consequences, which can be used for decision-making tools. There is still a lack of generalized quantifications of robustness, which should be derived based on the definition and design objectives and on the response of a structure to local damage as well as the associated consequences of collapse. Critical issues and recommendations for future design and research on quantification of robustness are provided from the views of column removal scenarios, types of structures, regularity of structural layouts, collapse modes, numerical methods, multiple hazards, degrees of robustness, partial damage of components, acceptable design criteria.

Recently, there has been an increasing interest in the migration of young people to local areas. These young people are discovering and reinterpreting local resources to open local businesses while generating new value in local activities and businesses. This study was initiated with the recognition that fundamental solutions are needed for these young people to settle and sustain residence in the local area. Edward Relph stated that 'place' is a fundamental attribute that influences human existence in the world and is the source of stability and identity formation for individuals. This is deeply related to the psychology of young people who have migrated to local areas. These young people accept the unfamiliar 'space' as a 'place' to form stability and personal identity. Therefore, this study utilized PhotoVoice methodology to examine the process and key factors of place identity formation among migrant youths. As a result, the study identified factors that enable young people to settle in local areas and sustain residence while recognizing elements the local government should focus on to support and address the influx of young people. The results of this study can serve as a foundation for addressing the declining population in local areas through the formation of a relationship population and spur the inflow of young people to local cities in the future.

This paper presents a local binary pattern(LBP) for effectively classifying textures, which is based on the multidimensional intensity difference between the adjacent pixels in the block image. The intensity difference by considering the a extent of 4 directional changes(verticality, horizontality, diagonality, inverse diagonality) in brightness between the adjacent pixels is applied to reduce the computation load as a results of decreasing the levels of histogram for classifying textures of image. And the binary patterns that is represented by the relevant intensities within a block image, is also used to effectively classify the textures by accurately reflecting the local attributes. The proposed method has been applied to classify 24 block images from USC Texture Mosaic #2 of 128*128 pixels gray image. The block images are different in size and texture. The experimental results show that the proposed method has a speedy classification and makes a free size block images classify possible. In particular, the proposed method gives better results than the conventional LBP by increasing the range of histogram level reduction as the block size becomes larger.

Since geologic data are often sampled at sparse locations, it is important not only to predict attribute values at unsampled locations but also to assess the uncertainty attached to the prediction. In this study the assessment of the local uncertainty of prediction for the thickness of the consolidation layer was performed by using the indicator approach. A conditional cumulative distribution function (ccdf) was first modeled, and then E-type estimates and the conditional variance were computed for the spatial distribution of the thickness of the consolidation layer. These results could be used to estimate the spatial distribution of secondary compression and to assess the local uncertainty of secondary compression for Songdo New City.

This research investigated the public rental houses In Yangchon-gu, whose locational attribute are suitable for the public rental house and has superior position in both inhabitants' participation and public welfare program. The public rental house has several types, such as permanent lease house, public lease. And several programs, the aged support police and medical services delivery system, have been the leading models for other local governments. Also, there are residents who are in their forties and fifties in the public rental houses in Yangchon-gu. un occupied is less than 1% and it seems that there is few turnover rate. 1 household rate and 2 households rate look like similar in the number of family member, total social public welfare program is focus on family welfare, juvenile welfare, teenager welfare, handicapped person welfare local, welfare and old people welfare. Accordingly, this research is used for base data of questionnaire and the first data for grope various improvement while planning group public rental house for low income group. And this research will be improved directional grope for improve livable public rental house around residents.

This study focused on 'The Health' which should considered as a precondition for the local residents by reinvestigating the indicators of happiness after Young-Do ward formulate a community social welfare plan. There is purpose of this study as below. I searched an general attribute and the indicators of happiness, then looked how does results from questions about health and factors of the indicators of happiness can affects the health with some kinds of elements. Five hundred people from the inhabitants of Young-Do ward who is living in Young-Do district were separated by using the random sampling method as the subject of the study. The investigation took effect from October to November of 2010 and an investigator visited the inhabitants of a ward with structured questionnaire. An investigator had one-on-one talk with inhabitants of Young-Do ward while the investigation and I also collected the data through self-administered questionnaire as well. I found the physical elements influence in the health much more than the outside factors from the study. Higher satisfaction of their career, relationship between friends and co-workers, work environment and married life reflects the fact that higher self-contentment means high quality health level.

The new Urban Park Regulation encourages local governments to introduce new types of urban parte such as historic parte, cultural parks and neighborhood parte. However ambiguity among those parks in terms of main facilities and providing recreational programs makes it difficult for local governments, as well as landscape designers and planners, to adopt this new regulations. In this light, the present study aims to search for park facilities and programs defined by the new regulations, in order to satisfy users' demands for those parks with consideration to parks' unique characteristics. For these purposes, a conjoint analysis was carried out with three hundreds participants. Sampled participants include the citizens of Seoul as well as current residents of Paju. The study results indicate that participants would like to have distinctive programs and facilities at these three new types of parks. However, no considerable differences were observed among the levels of programs and facilities participants wish to have, due to unfamiliarity with, in particular, cultural and historic parks. Despite this insignificant difference among attribute levels, study results clearly suggest that residents wold like to have new types of facilities and recreational programs.

The objective of this study is to analyze the value of attributes of agricultural products in school food service using hedonic price model and choice experiment. In the case of potatoes, bean sprouts, and tomatoes, environment-friendly agricultural products rather than conventional ones, and domestic price premiums exist rather than Chungnam. The higher the price, the higher the margin rate. Conventional agricultural products were more profitable than environment-friendly ones, and domestic products were more profitable than Chungnam. In consumer preferences, environment-friendly agricultural products are preferred over conventional agricultural products and local products (Chungnam, Cheonan, Asan) rather than domestic ones. This is the opposite result of the Hedonic price model estimation that Chungnam has a lower price premium than domestic in the case of origin. This study is meaningful by analyzing the attribute value of agricultural products used for school meals in Chungnam and comparing them with the willingness to pay consumers. With the results of this study, it is necessary that discussions on supplementing the value of local products used in Chungnam school food service.
