  • 본 연구는 GIS공간분석기법과 Huff의 확률모형을 이용하여 근린생활권중심의 상권분석을 수행하였다. 연구에 사용된 기본도는 청주시 복대동을 대상으로 하여 업종, 세대수 등을 현장 조사하여 구축하였으며, 기 구축된 LMIS에 있는 연속지적도를 활용하였다. 분석에서는 커널밀도함수(Kernel Density Function)와 최근린지수(Nearest Neighbor Index)를 활용하여 근린생활권내 점포분포 중심권역을 설정하였다. 상권분석을 수행하기 위하여 설정된 중심권역에 따라 중심지(점)와 규모를 산출한 후 상권분석의 모형인 Huff 확률모형에 적용하여 중심권역별 상권을 추출하였으며, 추출된 상권을 지도로 도식하였다. 따라서 본 연구에서는 GIS 공간분석기법 중 커널밀도함수와 최근린지수를 통해 Huff 확률모형에 적용할 수 있는 방법을 제시하였다. 이러한 방법들을 이용함으로써 보다 정확하게 상권분석을 할 수 있으며, 향후 창업하고자 하는 소상공인들에 도움이 될 수 있으리라 사료된다.

  • Morphological information such as shape and margin of micro lesion is important information for diagnosis of disease in clinical imaging. In this study, we investigated the morphological changes of the micro lesions by comparing the contrast and area in grid suppressed DR images according to grid frequency. In the profile analysis of the image, the mass showed an average intensity variation of 8.6 ~ 72.4 after suppression, The higher the grid frequency, the more the contrast was increased. However, in the images obtained using 103 lp / inch, which is a grid frequency less than the sampling frequency, the contrast of the mass in the vertical direction decreased after suppression. In the binary image, the area change of the mass was also large. As a result, the shape, size, and margin of the mass changed. In the case of very small calcification, the higher the grid frequency is the larger the change in contrast, so that a clear image can be obtained in the post-suppression image. However, we could confirm that the margin of the lesion was blurred and the lesion was lost in some of the images using the 103 lp / inch grid. The higher the frequency of the grid, The change of the contrast of fiber occurred largely and clear boundary was confirmed. The decrease of the number of pixels was small and morphological change was small. In conclusion, when using a grid frequency that is not suitable for the sample frequency, morphological changes or lesion loss of micro lesions in the post- suppression image may give the possibility of misdiagnosis in diagnosis and differentiation of the image.

  • From the mid-1990s, the discussion on alternative schools began in earnest, and with the increasing interests in them, Korean parents' association of alternative education, KPAAE was launched formally in November, 2008. Among the alternative schools in the nation, thirteen urban alternative schools were studied and analyzed. The result indicated that they are being run by individuals and civic organizations with no approval and the facilities and spatial organization of the schools are poor, which is thought to be mainly due to financial reasons as well as the schools' educational goal that puts emphasis on experiences leading to utilize outside local facilities. With this background, the results from the analysis of the facility status and the spatial organization of urban alternative schools led us to understand the followings: First, it showed that per capita average of area of the urban alternative school is approximately 11.995m$^2$, less than 14N, the standard area of institutional schools. Second, depending on the form of facilities, the space of other facilities is shared to make up for insufficient space, and is utilized to a small degree and for multi-purposes. Third, the space reflects the disposition of subject students, and is located in the area with convenient traffic for students' attending the schools conveniently. Fourth, specialized space is run on the basis of educational goals, and the exploring of career and the improving of sociality are pursued through internship programs associated with local facilities. Thus, it is desirable for the minimum per capita area of the urban alternative school to meet 14N, the standard area of the institutional schools in order that the urban alternative school may overcome the spatial limitation and the financial hardship stemming from the practically difficult constructing of new buildings and the small scale operation, and it may make flexible use of the space, and the students may live their lives smoothly. Also, it is thought that for the activating of the urban alternative schools, the plans for utilizing various facilities associated with local facilities should be considered.

  • 본 연구는 북한산 국립공원을 대상으로 등산로가 산림경관의 파편화에 미치는 영향을 분석한 후, 이를 토대로 소유역별 경관생태학적 건전성을 평가하였다. 등산로 개설에 의한 영향 분석 결과에 따르면, 산림패치의 크기는 감소한 반면 패치 및 가장자리 밀도는 증가한 것으로 나타났다. 또한, 패치형태는 보다 복잡해지고, 핵심지역의 면적은 뚜렷하게 감소하였고, 패치간의 근접도는 증가하는 것으로 나타났다. 한편, 소유역별 경관생태학적 건전성 평가 결과, 종합적인 건전성은 북한산유역이 3.7점으로 가장 높게 나타났으며, 구기유역이 1.6점으로 가장 낮게 평가되었다. 이상의 결과를 종합해 볼 때, 산림의 경관생태학적 보전과 관리를 위해서는 불필요한 등산로의 개설을 금지하고, 훼손 및 교란 지역에 대한 자연적인 생태학적 복원이 이루어져야 할 것으로 판단된다.

  • 2019년 현재 우리나라 인구 10만 미만인 소도시의 평균 고령화율이 약 31.8%에 이르고 있음에도 각종 생활편의시설이 읍면의 일부 중심지에 집중되어 있어 특히 고령주민의 이용에 많은 불편을 초래하고 있다. 본 연구는 이들 지역에서의 고령자 생활편의시설에 대한 접근성을 실증적으로 밝혀, 향후 연구에 대한 기초 자료를 제공하는 것을 목적으로 하였다. 연구대상 지역의 인구 고령화 정도와 고령자 생활편의시설의 분포현황을 통계청 농림어업총조사의 지역조사 MDIS자료를 중심으로 구축한 후, 고령자 현황과 생활편의시설의 분포도 및 핫스팟맵 작성, 접근거리를 QGIS로 분석했다. 분석결과, 특히 고령자들이 많이 거주하는 지역에서의 의료, 판매, 위생 노인복지부문의 생활편의시설 접근성이 부족함을 확인하였다. 이는 소도시의 심각한 고령화를 반영한 고령자 생활편의시설의 유형 변화 및 공간적 재편이 필요함을 시사한다.

  • This paper describes performance improvement of GPS/DR Integration system using area decision algorithm and vehicle movement information. In GPS signal blockage area, i.e., tunnel and underground parking area, DR sensor errors are accumulated and navigation solution is gradually diverged. We use the car movement information according to moving area to correct the DR sensor error. Also, vehicle movement is decided as stop, straight line, turn and movement changing region through DR sensor data analysis. The car experiment is performed to verify the supposed method. The results show that supposed method provides small position and heading error than previous method.

  • The purpose of this study is to clarify the actual conditions of the floor area of skilled nursing facilities in rural area. The thorough investigation and observation works were made from the viewpoints of floor area of the skilled nursing facilities. This article discusses about the basic condition and the floor area for daily living activities of the elderly in 3 skilled nursing facilities in west gyeongnam province. As the result, There is a wide gap between floor area ratio of skilled nursing facilities. The characteristics of the private establishment skilled nursing facilities in the west gyeongnam province were figured out through the analysis of spatial composition in skilled nursing facilities for the elderly. The skilled nursing facilities in west gyeongnam mainly focus on the living environment orientated toward the bedroom. The difficulty is to encourage the communication between the skilled nursing facility patients because the facilities are composed of small semi-public zone.

  • The purpose of this study is to clarify the actual conditions of external space of middle and high schools in Gyeongnam Area. This article discuses about the characteristics of the external space and the site plan type of 49 middle and high schools in Gyeongnam Area. The result of analysis about site plan type, composition state of external space and area ratio of its composition of each middle and high school facilities are as follows: In facilities arrangement of middle and high schools, it shows diverse forms of arrangement from existing uniform straight type, however, most of schools do not being against the simple in their external space. Especially, for the area is small in the composition of external space, a playground is only under $50m{\times}80m$ and outdoor learning space or resting space is not secured sufficiently. Therefore, it requires an expansion of space size and facilities for the change of school life outside class.

  • When we urgently need to develop and supply an alternative energy, wind power is growing with much interest because it has relative low cost for generating power and small area for wind turbine. To estimate the wind power resource, it is necessary to make an observation first. Although the large wind farm and resources are near coast and mountain area, the wind energy in urban area has the strong thing of direct access to power generator. In this study, we estimate the probability of wind energy in urban mountain area using A2C (Atmospheric to CFD) model, which is used for horizontally urban scale phenomena. In the steady state results, the site C is most suitable for wind power in the point of the only wind speed. But, estimating the TKE and vertical wind shear, the site B is showing the better results than the site C.
