  • A historic urban landscape has to be preserved wholly, not only as a cultural heritage site, but also as an environment and a neighborhood. However, cultural heritage sites have their own unique social-commercial environments, and these are not easy to integrate during the preservation process even though they are located in the same area. To examine ways of overcoming the difficulty in integrating the preservation of heritages, this study analyzes the historic urban landscape preservation of St. Augustine, Florida in the United States. The preservation of St. Augustine's historic urban landscape can be identified by its unique system of government-academy cooperation. For integrated preservation of the historic landscape of St. Augustine, Florida's state government owns the properties, which are not designated but have a heritage value, and are located next to the nationally designated heritage sites. The properties receive trust administration by the University of Florida. This cooperation between the government and the university can benefit both stakeholders. To the government, the relationship gives the benefit for professional, long-term management for the properties and their environments. To the university, the cooperation provides a place for practical education, funding, and opportunities for research and management. The government-academy cooperation model argued for this study can be applied to many Korean historic cities' urban landscape preservation planning.

  • As de-schooling students (students who leave schools) have been produced and increased in middle and high schools every year since 1990s, urban alternative schools have founded with Seoul as the center. The objects of such urban alternative schools are de-schooling teenagers, and their educational goal is to make the students to discover their own values and grow as members of the community by accomplishing their healing and growth. Most of students in alternative schools have excessive self-centered feeling than ordinary people, and since they don't have exchanges with others, they have to receive holistic healing along with education. Here, 'healing' is a method of approaching to health through environmental, psychological, social and cultural supports unlike 'treatment' used for medical means. Therefore, holistic healing for alternative schools' students has to accomplish self-knowledge, self-control, and self-healing without repulsion through spaces of healing environments instead of heavy-handed exchanges. This study has integrated a theory of Max $L{\ddot{u}}scher$ who suggested a psychological healing theory in terms of internal character and a theory of Rudolf Steiner who suggested it in terms of practical and holistic sense and analyzed Sungmisan School, one of urban alternative schools in Seoul through the integrated theory. The analysis of the integrated theory are intended to emphasize the importance of healing environments and suggest methods in creating healing environments for urban alternative schools in the future.

  • Purpose: In spite of many Healthy Cities projects in Korea, there are few research about healthy urban planning. So we tried to use available recent models to a Healthy Cities project in a medium sized city in Gyeongnam province. Methods: Using mainly European Healthy Urban Planning Model and opinion leader survey, SWOT analysis, forum and discussion have been done to a city. Secondary city health indicator obtained from Ministry of Statistics. Results: There are strong need to develop health industry, green traffic and healthy living from survey using Healthy Cities policy direction of Korean Health Promotion Fund. Among the Healthy Urban Planning objectives, improvements of physical environments, prevention of accidents and crime, improvements of healthy esthetics rated highly. Although environmental pollution was problem local government push forward to the pilot healthy urban project as active healthy water-front development. Considering secondary healthy city indicators, change of external forces and internal capacity final task for healthy urban planning for Yangsan city were development of riverside physical education park and active living and anti-ageing environments etc. Conclusions: Comprehensive assessment and plan was possible through MAPP Model using European Healthy Urban Planning objectives to draw the direction of future urban planning for Healthy Cities Projects. Further research and formal introduction would be needed.

  • Mobile Ad Hoc Network(MANET)은 잦은 경로 단절과 경로 재설정으로 인한 지연 때문에 차량환경에 적용이 쉽지 않다. 이런 문제를 해결하기 위하여 VANET(Vehicular Ad Hoc Network) 알고리즘이 제안되었으며, 이들 중에서 위치 정보 기반의 라우팅 프로토콜이 유용한 것으로 알려져 있다. 도심환경에서는 차량의 잦은 이동과 함께 높은 건물들로 인한 전파 방해로 빈번한 네트워크 단절을 일으키지만 현재의 VANET은 이러한 도심환경을 고려하지 않기 때문에 토폴로지의 단절이 빈번히 일어난다. 본 논문에서는 도심환경 내에서 노드들의 이동방향을 측정한 후 캐쉬 테이블을 통하여 비교하여 교차로를 탐색하는 방법을 개선하고, 전송 홉 수를 최대한 줄여 전송효율을 높이는 라우팅 알고리즘을 제시한다.

  • Ant communities are well suited for monitoring changes in ecosystems. Although numerous studies have examined the responses of ant communities to environmental disturbance, relatively few long-term studies on ant communities have been undertaken in urban environments. We examined species richness in nine urban parks in Hiroshima, Japan, and compared the survey results with data collected at the same sites by using the same methods in 1999. In both surveys, total of 25 species was recorded: 23 species in 1999 and 20 species in 2012. Non-metric multidimensional scaling analysis revealed that the ant communities consisted of two distinct groups, which could in turn be characterized by three patterns of ant community changes in between the two groups. The first of these community change patterns was characterized by a shift within group 1, but the number of species remained constant (approx. 10 species). The second pattern was characterized by a shift within group 2, but the number of species remained low (approx. 4 species). The third pattern was characterized by a shift from group 1 to group 2 as the abundance of Linepithema humile (Mayr) increased over time. Unlike the first and second patterns, the number of ant species in communities of the third type decreased significantly. These findings suggest that L. humile has a marked effect on the species diversity of indigenous ant communities in urban environments.

  • As the elderly population increases, concerns for the elderly's welfare become greater both quantitatively and qualitatively. In order to give a chance for the elderly to live in familiar dwelling and regional context to which they are accustomed, and to participate in their society actively, it is of great importance that suitable living spaces must be provided for the elderly. The practical ways of providing people with good living environment and its easy maintenance for healthy and valuable lives were discussed in this paper. This research is designed to propose pertinent policies related to social issues concerning the elderly. 137 seniors over 60 living in Gwanaju city were sampled and surveyed. The scope of planning for the elderly's lifestyle and welfare is divided into two parts, one is planning of space for the realization of stable and spacious dwellings and another is urban environment planning capable of supporting healthy and affluent lifestyles. Also, the realization of stable housing, the construction of urban structure for a healthy life, and the provision of barrier-free living conditions are investigated. For increasing the degree of stabilization and improvement for the elderly's life, self-governing bodies should grasp the demands of living condition and spatial requirements by taking the lifestyles of the elderly into account in urban or regional levels. Then, a master plan including development, improvement, execution, and maintenance of proper housing facilities and urban environments should be made for the best results.

  • Roof gardens/Rooftop farm are most often found in urban environments. Plants have the ability to reduce the overall heat absorption of the building which then reduces energy consumption. Plant surfaces however, as a result of transpiration do not rise more than $4-5^{\circ}C$ above the ambient and are sometimes cooler. As Urban agriculture in an accessible rooftop farm, space becomes available for localized small-scale urban agriculture, a source of local food production. An urban garden can supplement the diets of the community it feeds with fresh produce and provide a tangible tie to food production.

  • Accuracy of an integrated Global Positioning System (GPS) / Inertial Navigation System (INS) relies heavily on the visibility of GPS satellites. Especially, its accuracy is dramatically degraded in urban canyon due to signal obstructions due to large structures. In this paper, we propose a new integrated positioning system that effectively combines INS, GPS, ultrasonic sensor, and barometer in GPS-denied environments. In the proposed system, the ultrasonic sensor provides velocity information along the forward direction of moving vehicle. The barometer output provides height information compensated for the pressure variation due to fast vehicle movements. To evaluate the performance of the proposed system, an experiment was carried out by mounting the proposed system on a test car. By the experiment result, it was confirmed that the proposed system bears good potential to maintain positioning accuracy in harsh urban environments.
