Like other organic beings, modern cities change every day. Unlike in the past, changes of space which have been taking place in concentrated spaces during short periods of time have worsened the environment of cities creating environmental problems. In particular, the urban heat-island phenomenon, which is caused by changes in using the earth's surface, has emerged as a key social issue along with health problems and economic difficulties. The Green Network has been introduced as an urban planning approach to solve the urban heat-island phenomenon. This study suggests constructing a Green Network through analyzing the urban heat island phenomenon, land cover classification, and linkage possibility with the Green Network and wind corridors by researching Jung-Gu, and Nam-Gu in Daegu Metropolitan City. In conclusion, this study presented the construction of a broad and detailed Green Network of object areas by assigning Apsan to the southern area and mountain area as the core, two areas of Nam-Gu and six areas of Jung-Gu such as Duryu Park and, Dalsung Park as footholds and other school land and park facility areas as footholds-to-be areas. In particular, Camp Walker, which is connected with Apsan, is not only a foothold but connected to the core, is necessary to preserve after being transferred from the U.S. Army. In addition, assigning the Susung Bridge area of Jung-Gu and the Camp Walker area of Nam-Gu as the wind corridor areas is recommended.

An arboretum is defined as a collection of facilities that conserve plant species by surveying, collecting, and proliferating and preserving the plants in nature, perform diverse researches on plants and display the plants in exhibition spaces or outdoors as well as provide the public with educational programs and refreshment spaces according to the laws concerned. The public, however, recognizes the exhibition and education functions on plants of arboretum more importantly compared with the roles to survey, collect, and proliferate plants as regulated by the laws. In particular, arboretum plays a role to offer a pivotal educational place in urban area where the public can obtain an hands-on experience and understanding on a wide range of plant species and natural environment. The study aims to estimate the non market environmental values of Daegu Arboretum operated by Daegu Metropolitan City government by using the Contingent Valuation Methods (CVM), which yields the current monetary estimates for the arboretum. The value estimation was undertaken by using the Double-Bound Dichotomous Choice (DBDC) method, and each estimated value was derived from respective functions based on a logit distribution known to include relatively stable estimates according to the shape of the distribution. Considering the statistical fitness test results, the author estimated the amounts of the Willingness To Pay (WTP) such as mean WTP of 12,718 KRW, median WTP of 11,033 KRW, and truncated mean WTP of 11,468 KRW, which represented the annual recreational values per a person visiting Daegu Arboretum respectively. The analysis showed that Daegu Arboretum created the annual environmental values which were estimated to be approximately 16 to 19 billion KRW. The study also has an implication that the valuation method for the environment of Daegu Arboretum may be effectively applied for estimating the values of other types of environmental goods by altering the locations or goods to be analyzed.

Background: This study uses the relevance index to understand the condition of regional medical service use for cardiovascular surgery and to identify the medical service use imbalance between regions. Methods: This study calculated the relevance index of 16 metropolitan cities and provinces using resident registration address data from the Ministry of Government Administration and Home Affairs and the 2010-2014 health insurance, medical care assistance, and medical benefits claims data from the Health Insurance Review and Assessment Service. We identified developments over the 5-year time period and analyzed the level of regional imbalance regarding cardiovascular surgery through the relative comparison of relevance indexes between cardiovascular and other types of surgery. Results: The relevance index was high in large cities such as Seoul, Daegu, and Gwangju, but low in regions that were geographically far from the capital area, such as the Gangwon and Jeju areas. Relevance indexes also fell as the years passed. Cardiovascular surgery has a relatively low relevance index compared to key types of surgery of other fields, such as neurosurgery and colorectal surgery. Conclusion: This study identified medical service use imbalance between regions for cardiovascular surgery. Results of this study demonstrate the need for political intervention to enhance the accessibility of necessary special treatment, such as cardiovascular surgery.

This paper has attempted to improve the quality of urban environment in terms of the management of urban green tract and suggest a way of coexistence between human and nature by proposing a plan to establish green network using an urban green zone based on 'linear concept' instead of point and plane concepts. The results have turned out as follows: 1. According to current status of forest functions, forest recreation area has reached 39.6%, satisfying citizens' needs. However, the space for living environment is just about 20% with a lack of a green zone. Therefore, it's been necessary to establish green network using roadside trees and take advantage of them as sustainable living space along with existing green tract. 2. With forest in the suburbs and Geumhogang which is the tributary to the Nakdonggang, Sincheon (stream) flows through the downtown. It connects mountains including Waryongsan from the south to the north around Duryu Park and Dalseong Park. Therefore, the water system that passes through Palgongsan (Mt.) and Biseulsan (Mt.) would make it possible to connect with the parks in the downtown. 3. According to this paper, it appears that it's necessary to establish green network through roof or wall greening by focusing on the existing green tract in the urban parks and suburbs and taking advantage of roadside trees and water system.

Link attributes, such as speed, occupancy, and flow, are essential factors for transportation planning and operation. It is, therefore, one of the most important decision-making problems in intelligent transport system (ITS) to determine the optimal location of a sensor for collecting the information on link attributes. This paper aims to develop a model to determine the optimal location of a sensor to minimize the variability of traffic information on whole networks. To achieve this, a network sensor location model (NSLM) is developed to reflect discrete characteristics of data collection. The variability indices of traffic information are calculated based on the summation of diagonal elements of the variance-covariance matrix. To assess the applicability of the developed model, speed data collected from the dedicated short range communication (DSRC) systems were used in Daegu metropolitan area. The developed model in this study contributes to the enhancement of investment efficiency and the improvement of information accuracy in intelligent transport system (ITS).

Purpose: The purpose of this study was to examine correlations among UPDRS, respiratory function, and senior fitness and to investigate the effects of restrictive respiratory function on these factors in Parkinson's disease patients. Methods: Subjects (n=25, Hoehn & Yahr (H&Y) stage: 2-3, $69.3{\pm}5.9$ yrs) from D Hospital Parkinson's Disease Center at Busan metropolitan area in the Republic of Korea volunteered for this study. They performed the pulmonary function test, UPDRS, and the senior fitness test. SPSS 18.0 was used for analysis of data, and the collected data were analyzed using Pearson's correlation coefficient (n=25). In addition, Independent t-test was used for determination of differences between two groups (between the normal pulmonary function group (n=10) and the restrictive pulmonary function group (n=10)). Results: Forced vital capacity (FVC (L)) showed significant negative correlation (r=-0.44, p<0.05) with H&Y stage in Parkinson's disease patients, and chair stand showed significant negative correlations (r=0.41, 0.43, 0.42, p<0.05) with FVC (L), FVC (%), and FEV1 (L). FVC (%) showed significant positive correlations (r=0.44, r=0.44, p<0.05) with right and left back scratch. In addition, the restrictive respiratory function group showed significantly lower FVC (%) (p<0.01) and was significantly slower (p<0.05) in the 8-foot up-and-go test than the normal respiratory function group. Conclusion: In conclusion, these results suggest that restrictive respiratory function in PD was related to H&Y stage. In addition, agility of PD patients was lower in the restrictive respiratory function group than in the normal function group.

In most of the urbanized cities, socio-economic attributes tend to cluster as patterns of similarity in space, namely spatial autocorrelation, by agglomeration forces. The classical linear regression model, the most frequently adopted in the trip generation step, cannot sufficiently represent this effect. In order to take into account the effect properly, we need a model which adequately deals with the spatial dependence patterns. In this study, the Geographically Weighted Regression (GWR) model is adopted as an alternative method for the local analysis of relationships in multivariate data sets; that is GWR extends this traditional regression framework by estimating local rather than global parameters. This study shows the existence of spatial effects in the production and attraction of home base/non-home based trips through the GWR model using travel data collected in Daegu metropolitan area. Furthermore, LISA is employed to verify the fact that the local spatial autocorrelation exists.

This paper identifies public transit-poors and derives spatial characteristics of the poors' distribution in an urban area by utilizing buffering analysis of geographic information systems and remote sensing techniques in the case of Daegu metropolitan city. Since special attention is given to elderlies, this study assigns three hundred meter buffer from bus/subway station as service boundary for elderlies. The results of this study tell us that 1) the transit-poors are concentrated on suburban and rural regions, 2) high proportions of the transit poors are elderlies with spatial variations in many regions, 3) the main housing type of the transit-poors is single detached house. We expect that this study can contribute to build an effective policy-making by showing essential technical processes and methods in identifying policy-need groups and their characteristics of spatial distribution.

This study examines organizational qualities such as vision, mission, teamwork, fairness, and empowerment and their effects on organizational members. As a result of analysis, these qualities are identified to affect member satisfaction, but not to affect job involvement. Member satisfaction affects job satisfaction, and this relationship retains indirect influence through an increase in member satisfaction. Further, improved member satisfaction and job involvement are found to affect organizational commitment. These results are derived from complete enumeration on members of an organization where particular traits such as member position, job classification, and the privity of contract are intermixed. In case where research is conducted on the aforementioned traits separately, different results would be anticipated depending on each trait. The implications of this study are as follows. First, clear-cut organizational vision and mission established by the top management of an organization prevent confusion amongst its members, and thus have the highest level of effect on member satisfaction. Second, teamwork in reference to the. relationship amongst team members of a work group and goal awareness improves member satisfaction. Third, autonomy for job performance and related empowerment improve member satisfaction. Last, fairness in wages and promotion affects member satisfaction. Therefore, internal qualities of an organization perceived by its members have a higher degree of influence over external qualities including compensation and promotion on the members. In addition, these internal qualities indirectly affect job involvement through an increase in member satisfaction, and, in turn, member satisfaction and job involvement affect organizational commitment of the members. In case of member satisfaction, not only does it affect organizational commitment of the members of an organization directly, but also affects organizational commitment indirectly through job involvement. This study is conducted with only one hospital in consideration, and thus its findings may not be generalized for every medical organization. However, this study retains distinct attributes of complete. enumeration, and the precedence of each variable is closely investigated.
