  • 부산대도시의 공간구조와 그 문제들에 관심을 가진 많은 도시 학자들과 연구자들이 부산대도시 공간구조에 대한 관리의 필요성을 오랫동안 제기하였다. 그래서 본 연구의 목적은 1993년, 2001년의 기간 동안의 인구밀도, 고용밀도, 지가로 부산대도시의 공간구조의 동적인 변화를 알아보는 것이다. 본 연구의 중요한 결과들은 다음과 같다. 도심의 인구유출을 경험하는 동안, 주변부는 지속적으로 성장하였다. 중앙동은 인구 잠재성의 높은 접근성을 가졌다. 그러나 그 접근성은 1993년 이후 줄어들고 있다. 부전동은 2000년까지 인구가 증가하는 경향을 보이나 그 이후 년부터는 인구가 감소하였다. 그사이에 주변부는 높은 접근성으로 인구가 증가하였다. 그래서 부산의 공간구조가 다핵도시로 바뀌었다. 이 현상은 기존의 도심에서부터 자발적인 인구분산을 일으키게 되었다. 지가 변화에서는 부산 도시화의 분포패턴을 보여준다. 부산의 가장 높은 지가는 CBD에서 나타나며, 부산의 발전은 남북 띠를 따라 나아가면서, 서부산 지역에 영향을 주었다.

  • Offshore wind turbine are subjected to more various loads than general land structures and the stability of structures is supported by the piles driven deeply in the subsoil. So it is more important for offshore structures to consider seabed soil-structure interaction than land structures. And the response of a fixed offshore structure supported by pile foundations is affected by resist dynamics lateral loading due to wave forces and ocean environmental loads. In this study, offshore wind tower response are calculated in the time domain using a finite element package(ANSYS 11.0). Several parameters affecting the vibration characteristics of the natural frequency and mode shape and the tower response have been investigated.

  • An attempt to clarify the landscape structure of urban areas was carried out on Mt. Hwangryung located in the center of Pusan, southern Korea. By means of aerial photographs and field survey, a vegetation map including land-use pattern was made. Landscape structure was described by analyzing the vegetation map. Landscape element types were classified into secondary forest, introduced plantation, and other elements including urbanized area. almus firma and Pinus thunbergii communities, introduced plantation elements, formed matrix and some secondary forest elements and the other artificial plantations of small scale tended to distribute as small patches in such matrix. The number of patches per unit area in secondary forest elements was more than that in introduced plantation element. The result on patech size was vice versa. As the results of landscape ecological analyses, it was estimated that differentiation of patches recognized in community level would be related to artificial interference and those in sub-communities levels to natural process such as progression of succession. On the other hand, restoration plans in viewpoints of restoration and landscape ecology were suggested to improve ecological quality of Mt. hwangryung.

  • 본고(本稿)는 부동산, 특히 토지에 대한 보유과세가 강화되어야 한다는 주장들을 검토하여 토지보유과세(土地保有課稅)를 강화하는 것이 바람직한가, 그럴 경우 어느 정도의 세부담(稅負擔) 증가(增加)가 필요한가를 살펴봄으로써 세제개편(稅制改編)의 실천적인 지침을 도출하는 데에 그 목적이 있다. 빠른 지가상승(地價上昇)이 계속되는 상황에서는 보유과세가 가진 효과들이 나타나기 어려우므로, 토지개발(土地開發) 및 공급(供給)의 확대로 지가상승(地價上昇) 추세(趨勢)를 완화시키는 한편, 양도과세(讓渡課稅)의 기능을 제고(提高)하는 것이 우선적으로 추진되어야 할 과제이며, 토지보유과세(土地保有課稅)의 증가(增加)는 토지정책적(土地政策的) 목적(目的)에서보다는 지방세수(地方稅收)의 확대(擴大)와 같은 목적(目的)을 위해 지속적으로 추구해야 할 정책방향이다. 토지보유과세(土地保有課稅)는 조세저항 등의 부작용을 보아가면서 점진적으로 높여 가되 보다 '좋은' 조세의 특성을 가지도록 개편해 가야 할 것이다.

  • 토지피복지도는 토지의 피복특성과 토지활용특성을 나타내는 자료로서 토지피복분류체계에 따라 계층적인 구조로 1998년부터 제작되고 있다. 대분류는 Landsat 위성영상을 활용하여 남 북한에 대한 작업이 완료되었으며, 중분류는 IRS-1C, IRS-1D, KOMPSAT, SPOT-5 영상을 저해상 컬러 영상과 영상융합을 한 후, 그 결과자료를 전문가가 도화하여 제작하고 있다. 특히 도화에 의한 중분류 토지피복지도 제작은 위성영상의 구매 및 자료처리, 토지피복 지도제작 과정에서 막대한 비용이 필요하다. 본 논문에서는 최근 많은 연구가 수행되고 있는 초분광 위성영상인 EO-1 Hyperion을 이용한 중분류 토지피복지도 제작 가능성을 연구했다. 많은 분광정보를 제공하는 Hyperion 영상과 기존에 사용하던 Landsat-7 ETM+ 영상의 토지피복분류 비교 연구를 수행하여 Hyperion의 분류정확도를 평가했다. 또한, Hyperion에 적합한 최적밴드선택 방법을 통하여 초분광 위성영상 활용의 효율성을 증대시켰다.

  • The Chosun Dynasty established and implemented measures to prevent Japanese invasion into the southern coast. To this end, the number of naval vessels and the number of ships were increased, and a shipyard(船所) was constructed to protect the safety of the vessels. The shipyard is a port facility where military vessels are anchored and repaired, as well as public facilities that are needed for military training on public and land, as well as facilities for storing supplies and equipment needed for ships on land and defense at the port entrance. Despite being such an important facility for national defense, Shipyard has not been noticed. Studies have shown that the position of shipyard is divided into the riverside type and the riverbank type, which is due to the topographical features of Korea. The repair cycle of naval vessels, the carrying out of Yeonhun(prevent the water from decaying the part of the ship, a raw tree was burned to smoke) and the place of sea training also affected the construction of the Gul River(掘江). The space structure of shipyard is divided into port entry facilities for monitoring and controlling at the entrance to the harbor, border facilities for folding and repairing military vessels, and land facilities for holding land exercises and administrative work of military vessels and military equipment.

  • The difference the guide specifications of between housing and land development has been caused many problems, since Korea Land Corporation and Korea Housing Corporation were merged into LH (Land and Housing Corporation) in 2009. Those are that specification criteria to establishing lower level specifications are disordered; duplicated investment on sites; management systems are conflicted site to site, which are based on different operation system from old land and housing corporations, etc. Thus, this paper aims to suggest a direction of integrated guide specification system of LH including improved and advanced classification hierarchy and specification.

  • In this paper, the radar altimeter for topographic mapping over land is introduced and the characteristics of the return signals are analyzed. The radar system is described briefly and the requirements to get the fine resolution of the terrain surface height are considered. The designed radar altimeter was tested on the landscape in the near of Stuttgart. The measured data shows very fine profile of the test landscape and the height errors induced from different geometrical structure of the land surface are acquired in the measurement. In the test area, most characteristics of radar return signals over land could be tested and the results of the topographic mapping using our radar altimeter can be used for future radar altimeter development for land applications.

  • This paper is focused on the sustainability of public rental housing policy. We have analyzed the general fiscal conditions of central government, the public welfare fiscal conditions, the public expenditure on rental housing, and the Korea Land & Housing Corporation (LH) financial structure. Central government fiscal conditions is controlled by the midium-term fiscal operation plan(2010~2014) and fiscal rules. And the fiscal mandatory expenditures on welfare is increased rapidly by the expansion of beneficiaries, but the fiscal discretionary expenditures particularly on public rental housing can be gradually cut down. LH, the dominant agency responsible for affordable housing, is now confronted with financial distress accruing to excessive burden for public rental housing construction. As a result this paper, we find the discrepancy between the fiscal conditons and public rental housing policies. We suggest the fiscally sustainable rental housing policy. Firstly, the construction plan should be realized reflecting the market and fiscal conditions. Secondly, the provsion and financing system of rental housing should be rebuild within the government fiscal condtions and financial ability of LH.

  • With the advance of radar technologies, the availability of synthetic aperture radar (SAR) images increases. To improve application of SAR images, a management system for SAR images is proposed in this paper. The system provides trainable land cover classification module and display of SAR images on the map. Users of the system can create their own classifier with their data, and obtain the classified results of newly captured SAR images by applying the classifier to the images. The classifier is based on convolutional neural network structure. Since there are differences among SAR images depending on capturing method and devices, a fixed classifier cannot cover all types of SAR land cover classification problems. Thus, it is adopted to create each user's classifier. In our experiments, it is shown that the module works well with two different SAR datasets. With this system, SAR data and land cover classification results are managed and easily displayed.
