Simulations of CMAQ with the High-order Decoupled Direct Method (HDDM) for a 2010 June episode are applied to estimate the influence of local and neighborhood emissions on ozone concentrations in the Kwang-Yang Bay (KYB) area. In order to examine ozone response to reductions in $NO_x$ and VOC emissions from KYB and Gyeongsang, ozone isopleths are generated with the first and second-order sensitivity coefficients from HDDM simulations at three sites; Taein, Samil, and Gwangmoo. Simulations show that reduction in KYB $NO_x$ may increase ozone over the sites. On the contrary, $NO_x$ reduction from Gyeongsang may decrease ozone at the sites when transport of ozone and its precursors from upwind Gyeongsang is potentially high. However, VOC reductions from KYB and Gyeongsang are favorable to lower ozone over KYB. The study implies that emission reductions for both local and neighboring areas are likely more effective to bring KYB to ozone attainment.

The intent of this study is to propose future planning guidelines and directions of the mixed-use buildings in the residential land development district in country-side cities, based on the concept that the neighborhood facilities are to be strategically laid out in a convenient location and planned in a proper manner for a healthy, safe, friendly and new neighborhood environment. For this purpose, seventeen mixed-use buildings which had been built in Shin-Eum housing development district in Gimcheon from 1995 until 2004 were chosen and investigated in terms of architectural characteristics in that process with surveying and analyzing those. The scope of investigation on case studies was that site size would be below 400 square meters, total area below 1500 square meters, and the number of stories below five stories high on the ground. Method of investigation on those was through field investigation, field photographs, recordings and drawings on those. Investigative contents have been divided and analyzed into the quantitative and qualitative factors in urban and architectural dimension. From results of quantitative investigations, five planning guidelines or directions could be obtained. From results of qualitative investigations, five planning guidelines or directions could be obtained. The criteria will be applied to new architectural developments of the neighborhood facilities linked with the small shops.

In this paper, we propose a new approach to learning a discriminative model for figure/ground segmentation by incorporating the bag-of-features and conditional random field (CRF) techniques. We advocate the use of image patches instead of superpixels as the basic processing unit. The latter has a homogeneous appearance and adheres to object boundaries, while an image patch often contains more discriminative information (e.g., local image structure) to distinguish its categories. We use pixel-level sparse coding to represent an image patch. With the proposed feature representation, the unary classifier achieves a considerable binary segmentation performance. Further, we integrate unary and pairwise potentials into the CRF model to refine the segmentation results. The pairwise potentials include color and texture potentials with neighborhood interactions, and an edge potential. High segmentation accuracy is demonstrated on three benchmark datasets: the Weizmann horse dataset, the VOC2006 cow dataset, and the MSRC multiclass dataset. Extensive experiments show that the proposed approach performs favorably against the state-of-the-art approaches.

The purpose of our study is empirically to identify residents' satisfaction by 'Dagagu' public rental housing and to find out another improvement to solve the housing problems facing the poor in Daegu. As a new way of settling the housing problems for the poor in city, as you know, 'Dagagu' public rental housing program was introduced by he Korean government in 2004 but rarely empirically evaluated so far. in the Residents' Satisfaction, There are no evaluation of 'Dagagu' public rental housing program except Kim's study(2006). Based on 160 survey data, we evaluated the 'Dagagu'. Public Rental Housing Program within the framework of affordability in economics, a satisfaction in building and in neighborhood by a statistical method. As a result, we find out that residents on 'Dagagu' Public Rental housing are satisfied with the 'Dagagu' Public Rental Housing Program by and large. For mitigating the housing and economic problem of the poor more, self-support program as well as assistance in housing are needed and 'Dagagu' Public Rental housing Program must include neighborhood program more.

This study is an attempt to present a model of the effective service area for branch library system planning in Dae Gu city as one of large urban public libraries in Korea. This model is built up through the analysis of the distribution of population and characteristics of community structure, based on the standard for the branch library system of a public library. The results are summarized as follows: 1. Under the circumstances of this country, each radius of the effective service area for branch libraries are as follows; $1{\sim}1.5km$. is adequate for the central library and major branches; 1km. for neighborhood branches; $0.5{\sim}0.8km$. for sub-branches. 2. Population within the radius of the effective service area of a given branch may range from 80,000 to 100,000 for major branches, from 50,000 to 60,000 for neighborhood branches, and from 20,000 to 30,000 for sub-branches. 3. The radius of the outer boundary for the effective service area may be between 4km. and 5km. from the heart of the city, and the inner boundary, 13.km. 4. Areas with the radius between 2km. and 3km. from the heart of the city may be selected as the most effective locations for branch libraries, and between 3km. and 4km. as the next priority. 5. The number of service areas may be 14, that is, 7 major branches(Sinam, Sinchun, Susung, Daemyung, Naedang, Dalsung, Rowon), 2 neighborhood branches (Pyungri, Nambu), and 5 sub-branches(Chimsan, Sangiuk, Bongduk, Hyomok, Dongchon)

This study was conducted to investigate the plant community and to propose ecological planning methods for urban environmental forest on Gaepo neighborhood park, Gangnamgu in Seoul. Thirty-six plots that the size of each plot was 10$\times$10m(100\ulcorner) were set up and the vegetation analysis was carried out. Field survey was executed Apirl, 1994. The actual vegetation was consisted of Poplulus$\times$albaglandulosa community(73.03%), Robinia pseudoacacia community(8.30%) P. $\times$ albaglandulosa-R.pseudoacacia community(1.81%) and environmental forest (15.22%) in the survey site. According to mean importance values of each plot, survey area were divided into ten forest communities. As for the analysis of plant community structure which was classified into ten forest communities, the importance values, ecological diversity, number of species, number of individuals, basal area and crown coverage of urban environmental forest were relatively lower than those of the native community. In urban environmental forest of Gaepo neighborhood park, it showed problems for the planting method. So urban environmental forest should be constructed considering ecological characteristics based on above results.

The disposition of public parks pursue proper distribution and hierarchy formations on the basis of the neighborhood units theory. However, problems like price of land has brought about a large gap between theories and real conditions. This paper examines the problems of the practical disposition and disposition standards of public parks to solve these contradictions with reference to examples in Japan metro-cities. Study results are as follows; 1) The existing disposition theories are based on the district-boundary of men’s acting and settling down. Therefore, the disposition standards of large-scale parks or special parks beyond the humane scale have not been explained exactly. 2) As city sizes have expanded, these large-scale parks have developed greatly, however, they are located out of urban areas on the ground of nature’s geographical features. As a result, many small parks developed in urban areas. This extreme phenomenon of location would break up proper distribution and hierarchy. 3) Large parks over 4 ha not only take an important role in forming greenbelts but their location is also mainly based on their natural geographical features so that they are absorbed into the network -structure of greenbelts. 4) It is suggested that in planning parks, location and size of large parks over 4 ha should be selected and decided in the relation not with parks but with greenbelts. Parks of 4 ha or below are properly disposed. Also, these parks take a great role in forming the district boundary for settling down. Accordingly, proper distribution and hierarchy formation needs to be based on established neighborhood as they were previously.

The purpose of this study is to analyze the effect of neighborhood environmental perception on park use for health. The study area is focused on neighborhood parks in Suseong-gu, Daegu city. The analysis results are based on questionnaires of 303 respondents. According to the results, park use for health improvement was significantly associated with the perceptions of accessibility to a marketplace, availability of public transit, accessibility to the park, enough sidewalks, number of crosswalks, and athletic population. The probability of park use increased by 2.326 times as the satisfaction of accessibility to the park increased. Also, greater athletic population, fewer crosswalks, and more sidewalks lead to increase of park use by 1.701, 1.617, and 1.642 times, respectively. Therefore, it is important to increase the available neighborhood parks around residences and to develop exercise programs that people can use continuously in order to vitalize park use for health improvement. Also, it is necessary to improve the convenience of walking such as development of pedestrian streets or malls between residences and parks.

The purpose of this study is to investigate the effects of poverty on the psychosocial adjustment of adolescents. Particularly, this study seeks to examine the mediating effects of neighborhood environments and parental depression. The 2008 'the Korean Youth General Survey' data were utilized. We analyzed data from 2,218 adolescents between the ages of 12 and 18 and their parents. We defined poverty as the income-to-needs ratio, and measured neighborhood environment using the degrees of neighborhoods' disorder, attachment, cohesion, and informal social control. Adolescents' externalizing and internalizing problem behaviors were used as indicators of adolescents' psycho-social adjustment. Structural equation modeling was utilized as the major analytic method. This study found that adolescents in low income families were more likely to reside in disadvantaged and dangerous neighborhoods. More importantly, the results revealed that psychosocial adjustment of the adolescents was indirectly influenced by poverty through the mediators, neighborhood environment and parental depression. Based on the results, we discussed policy and practice implications, including various interventions that may improve parental mental health and neighborhood environment of low income communities.

The rapid increase in the number of climate disasters combined with the scale of change and the diversification of natural disasters require a radical solution. In particular, the urban space is more complex, therefore we need to establish measures for disaster response and how to react to damaged infrastructure based on the phenomenon of an increase in the urban population and the impermeable layer being extended. The social problems related to the economic burden of land purchase and the securing of a disaster prevention system can be solved simultaneously by introducing the park system for disaster reduction into the public land of the green space in the city. The local government has recently adapted diverse systems of disaster mitigation and carried out pioneer projects according to the guidelines for the construction of the urban park for disaster prevention published by the Ministry of Land, Infrastructure and Transport. The purpose of this study is to propose a composition model for neighborhood parks to prevent disaster through urban green spaces which has the functions of water management and biotope conservation. The result of this study will contribute to utilize the climate change adaptation model for living area neighborhood parks in the existing urban structure.
