  • This study was carried out to establish a management plan for urban forest trails with analysis of trail damage types and soil physicochemical properties on 3 urban forest parks in Jinju, Gyeongnam-do. We found that soil hardness was significantly higher in forest trails than forest area at 0 cm and 5 cm at a significance level of 0.05. However, we could not find any significant differences for other soil properties. For the trail damage types, the most common types were as follows: trail expansion (66%), trail erosion (59%), side road (57%), and trail boundary erosion and root exposure (41%). The results showed no difference in most of these types between the trails and forest area, indicating that the forest area might be damaged as well as the trails. Priority should be given to prepare measures that prevent soil compaction from overcrowded hikers.

  • ICTs(Information and Communication Technologies) have changed the ways of social activities and communications, and in the process, online and offline spaces have been thought of as binary spaces in which online spaces substitute and erode offline spaces. The aim of this study is to explore how urban space where local social activities and communications are performed is constructed in terms of timespace through the intersection of online and offline communications and how the urban space is 'remediated' through online spaces. For this, the study looks at the case of a workshop on 'locality education' held at the Yeungnam University Museum in January 2013. Criticizing the dichotomist viewpoint that increasing in communications through online spaces results in the expansion of 'absent presence' or 'placelessness' in offline spaces, the study argues that online spaces remediating offline spaces are spaces not transcending the timespace constraints of the offline spaces but rather reflecting the spatial, temporal, material, social, cultural environments of urban space and place.

  • This study purposed to examine elderly welfare facilities by type, to analyze their local variations, and ultimately to contribute to the expansion of elderly welfare infrastructure. The results are expected to help inspect elderly welfare infrastructure for providing the aged with social services before the execution of 'the insurance for elderly long term care' and establish welfare facilities by area in the future. For these purposes, we used the national data "The Current State of Elderly Welfare Facilities in 2007" produced by the Ministry of Health and Welfare. We digitized elderly welfare facilities in 163 cities and counties by type and analyzed them by area. We also examined the differences in the local distribution of representative elderly welfare facilities such as elderly welfare centers, home based facilities (home helper centers), asylums for the aged and elderly care facilities in 16 cities and provinces. Furthermore, we analyzed differences and problems in their local distribution urban areas, mixed areas of urban and rural communities, and rural areas. In addition, we studied the current state of institutionalized care and home based care, which are two major directions of current elderly welfare policies, based on the local distribution of facilities and analyzed differences in the trends according to area. According to these results, the urban had more home based care facilities than the rural. However, the rural had more institutionalized care facilities than urban. Also, each local self-governing body showed unique characteristics. Therefore, these results suggest that we need to establish elderly welfare policies based on the distribution of facility types by area.

  • Urban development is a cause of expansion of impervious area. A permanent storage is operated as a method of reducing runoff of watershed. The purpose of study is to propose reasonable choice of simulation model for rainfall-runoff in the prior review system on disaster effect. First, we indicated problem about concentration time choice in the flood simulation. To test the adequacy of a rainfall-runoff simulation model, We analyzed characteristics of rainfall-runoff about urban and natural watersheds. A simulation model was calibrated with the storm of july 7 to July 9 in 2009. From the result, we proposed that SWMM and kinematic wave method as the flood simulation models for urban and natural watersheds. A simulation model and design method of a permanent storage for flood that is proposed in this study will be useful for practical design of flood simulation. The hydrologic analysis method of the study can be used for capacity evaluation of permanent storage plan.

  • With the massive expansion of cities in the 20th century, many fragmented small spaces are emerged. This research establishes a framework for analysis based on forward theories, and takes the development of small spaces in Busan as an example, draws conclusions through analysis, and construct a design model for the effective use of small spaces. Based on the theory of spatial design research, statistical analysis methods are used to analyse the effective use of fragmented small spaces in city. In order to provide guidance and reference suggestions when analyzing and researching this type of space design on the data collected from the survey in the future. The design of small spaces is a way to improve the efficiency of the space utilization through the reasonable design of this type of spaces. Urban space is designed to meet the requirements of urban residents as well as to consider the sustainable development of the environment and resources, society and culture. Meaningful solutions are proposed for the construction and development of the sustainable of the future urban spaces.

  • This study analyzed the status of urban agricultural regulation of metropolitan governments on supporting multi-dimensional values to suggest a direction for improving urban agriculture regulations. Moreover, a Delphi survey was conducted to derive ways to identify improvement opportunities for functions that showed relatively insufficient support for urban agricultural regulations. As a result of the study, 12 out of 17 metropolitan governments and 116 of 226 municipalities have enacted urban agricultural regulations. However, the enactment of urban agricultural regulations has generally declined since 2011. Analysis of the contents of the urban agricultural regulations showed that they focused on matters relating to the creation and expansion of the foundation of urban agriculture. Among the multi-dimensional values of urban agricultural regulations, the foundation for supporting the securing of green spaces and utilizing food production functions was most widely available. On the other hand, the foundation for support of resource recycling, healing and health, social welfare, economic imbalance mitigation, and job creation functions has been shown to be relatively insufficient. A Delphi survey conducted to determine potential measures to improve urban agricultural regulations to support these functions found that 17 of the 18 ordinance improvement measures were valid. Therefore, to revitalize the multi-dimensional values of urban agriculture, it is first necessary to enact new ordinances. Also, to revitalize the multi-dimensional values of urban agriculture evenly, it is necessary to revise the ordinances to include resource recycling, healing and health, social welfare, mitigation of economic imbalances, and job creation functions. In this process, the development of urban agriculture technology, legal review of various urban farming spaces, and fostering of industries related to urban agriculture are necessary. Above all, steady interest in the multi-dimensional values of urban agriculture and the efforts of local governments to foster urban agriculture must be supported.

  • Recently, small-scale excavation like ground cavity restoration and buried pipe replacement works are being carried out in urban area, in order to improve living convenience. This paper describes experiment results on the ground reinforcement method that can reduce the buried pipe damage, when the differential settlement occurred due to poor compaction of ground below the buried pipe. Plate load tests were conducted to evaluate a reinforcement effect of ground using concrete mat and expansion mat in the ground below the buried pipe. The results showed that the stress reduction ratio by concrete mat and expansion mat according to the surcharge load was about 46%~48% and 39%~42%, respectively. Therefore, the differential settlement of the buried pipe and the ground deformation below the buried pipes were reduced by the reinforcement effect of the concrete mat and expansion mat. This means that it is possible to prevent a buried pipe damage due to underground cavity and ground subsidence, if concrete mat and expansion mat are reinforced in the ground below the buried pipe or on the ground between the buried pipes.

  • Urban freight system includes not just intra-urban freight movement but also inter-urban movement as well. Hence, to make Busan a hub of North-east asia freight movement it is necessary to develop a comprehensive plan for infrastructure expansion as well as improvement of freight system based on the present facility situation. This study identifies the status of freight facilities in Busan by establishing the freight related infrastructure Database(DB) utilizing Geographic Information System(GIS), and to enable planners and decision-makers to utilize the DB to develop a future plan. The DB includes port facilities, major and minor arterial roads, railroad lines and facilities, depots, center city business areas, and urban infrastructures which are related to the freight movements. The analyses show that major transportation facilities in Busan consist of roads, railroads, coastal transportation, and international transportation, and it was found that intermodal facilities are inadequate for freight system in Busan. The results of this study will be useful for freight experts and planners to develop a comprehensive freight system plan.

  • This study was conducted to determine factors causing urban temperature rises in a mixed urban and rural city in Korea. The study site was Miryang City. For this study, temperature changes over a 36 year period from 1974 to 2010, as well as changes made in the urban environment of the city were examined. Changes in the urban environment included data pertaining to both urban development and changing land use, as well as the changing lifestyle patterns of the populace. The study showed that a rise in the average annual temperature and the average annual mean-maximum temperature were statistically significant and the greatest determining factor for the temperature rise was a corresponding decrease in arable land. The study also showed that the decrease in cultivated land was directly and significantly related to an expansion of regional urbanization. There is a direct relationship between the decrease in cultivated land and an increase in the annual-mean-maximum temperature compared with annual-mean temperature. This increase can be explained as arable land works as an "island" of cooler temperatures in the hottest times of the day. A decrease of $1km^2$ of arable land is expected to cause an increase of $0.08^{\circ}C$ of annual-maximum-mean temperature and $0.06^{\circ}C$ of annual-mean temperature.
