        게이티드 커뮤니티의 공간적 영향 분석 및 도시 공공성 개선방안

        김지숙,김호용,KIM, JiSook,KIM, Ho-Yong 한국지리정보학회 2022 한국지리정보학회지 Vol.25 No.1

        Recently, the gated community has been increasing due to various reasons such as demand for differentiated areas and security, but various problems have been raised, including regional conflicts, traffic restrictions and disconnection of surrounding areas. Therefore, this study empirically considered what kind of spatial effect the gated community has on the surrounding area by analyzing the vitality using floating population big data and analyzing pedestrian accessibility using network analysis and social network analysis. As a result, it was found that the overall vitality in the study area was greatly affected by the land use and the building use. However, focusing on apartment complexes, even in the same land use, when the form of the complex is open to the outside, there is a lot of floating population, so the vitality is high. In terms of accessibility, assuming that the gated community is open, it was found that as the physical connectivity improved, there were more roads for pedestrians to choose from, and the accessibility improved as traffic and exchanges occurred in the disconnected space. The value of improving property rights and residential environment is also precious, but it is necessary to review how to reflect the improvement of local permeability in enhancing the publicness of cities and the value and direction of communities that can coexist with the region.

      • 지형요인에 의한 일조권 침해의 영향 분석

        김지숙,김호용,이성호,Kim, Ji-Sook,Kim, Ho-Yong,Lee, Sung-Ho 한국공간정보학회 2011 한국공간정보학회지 Vol.19 No.1

        최근 대도시지역의 고밀화와 주거환경에 대한 관심의 증가로 인해 일조권 확보를 위한 분쟁이 빈발하고 있다. 일조권 분석에서 정확한 일조 침해여부를 분석하기 위해서는 주변 지형 지물의 영향으로 인한 일조시간 변화를 고려하여야 한다. 이에 본 연구에서는 정확한 일조 침해분석을 위하여 부산광역시를 대상으로 HV 알고리즘을 이용하여 지형에 의한 일조시간 변화를 분석하였다. 분석결과 첫째, 표고가 50m 증가함에 따라 대상지역의 최소일조시간과 평균 일조시간이 감소하는 지형에 의한 영향이 나타났다. 둘째, 법적 기준에서 지정된 시간범위에서 최고 78.6%에 해당하는 지역이 일조시간에 영향을 받았다. 셋째, 주변지역의 지형별 특성이 일조시간에 큰 영향을 미치고 있었다. 따라서 정확한 일조권 분석을 위해서는 반드시 주변지역의 지형에 대한 고려가 필요하다고 하겠다. 또한 본 연구에서 사용된 HV 알고리즘과 그 결과로 나온 하늘에 대한 가시권은 실질적인 일조권 분석에 앞서 법적 일조시간에 영향을 미치는 주변지역의 지형에 의한 영향을 분석하기에 도움이 될 것으로 간주된다. With the recent overcrowding of metropolitan cities and people's increasing interest in housing environment, there are frequent disputes occurring over the right to daylight. In order to determine whether daylight has been encroached accurately. we need to consider the daylight change by the effect of the geographical features of the surrounding areas but most of the previous relevant studies overlooked this consideration. Thus, in order to determine the encroachment of daylight accurately, this study analyzed the change in the duration of daylight according to geographical features by applying the Hemispherical Viewshed Algorithm to Busan Metropolitan City. According to the results of the analysis, the minimum and average duration of daylight decreased with an increase of altitude by 50m. Second, according to the time bound designated by law, up to 78.6% of the area was influenced by the duration of daylight. Third, the geographical features of the surrounding areas had a significant effect on the duration of daylight. Accordingly, in order to analyze the right to daylight accurately, it is essential to consider the geographical features of the surrounding areas. Furthermore, the Hemispherical Viewshed Algorithm used in this study and the visible area of the sky obtained from the algorithm are considered helpful to analyze the influence of the geographical features of surrounding areas on the legal duration of daylight before analyzing the practical right to daylight.

      • KISIA가 말하는 보안기업 이야기 - 위협 수집기 TMS

        김지숙,Kim, Ji-Suk 한국정보보호진흥원 2009 정보보호뉴스 Vol.136 No.-

        국내 정보보호 기업의 약 60%는 벤처 창업 붐이 최고조에 달했던 1999년$\sim$2003년 사이에 설립됐다. '정보보호기술' 역시 약 10년 전인 2000년에 창업한 기업 중 하나다. 2000년 전후로 국내 IDS 시장이 활성화되던 당시 '테스(TESS) IDS'로 정보보호 제품을 선보인 정보보호기술은 기술력을 바탕으로 비교적 짧은 시간 내 정보보호 분야에서 탄탄한 기반을 다지게 된다. IDS를 통해 시장 점유율을 높이던 정보보호기술은 2004년 자체 IDS 개발 기술을 바탕으로 당시에는 생소했던 '위협관리시스템'을 내놓으며 신선한 바람을 일으켰다. 보안산업의 새로운 분야로 떠오른 위협관리시스템은 사후 대응이 아닌 위협요소에 대한 사전대응을 목표로 한 예/경보 시스템. 정보보호기술의 위협관리시스템 'TESS TMS(Threat Management System)'은 기존 IDS가 가진 분석기능과 모니터링 기능에서 출발했다.

        치아재식시 골형태형성단백이 치주조직 치유에 미치는 영향

        김지숙,박준봉,이만섭,권영혁,Kim, Ji-Sook,Park, Joon-Bong,Lee, Man-Sup,Kwon, Young-Hyuk,Cho, Kyoo-Sung 대한치주과학회 2002 Journal of Periodontal & Implant Science Vol.32 No.3

        The purpose of this study is to evaluate the influences of the bone morphogenetic protein (BMP) on the healing of periodontal ligament and alveolar bone after replantation of tooth, and to examine the possibility of its clinical application. 45 Sprague Dawley rats weighted about 100 gram were divided into 3 experimental groups by different dose of BMP. All the upper right and left 1st molar were extracted after 5 days feeding of 0.4% ${\beta}$-aminopropionitrile, and right molar were used as experimental group and left molar were used as control group. The root surface of experimental molar were treated with 25,50 and l00ng/ml of human recombinant Bone morphogenetic protein-4 (rh-BMP-4) with micropipet, and 1M Sodium hypochloride were used on control root surface. All the experimental animals were sacrificed as 1, 2, 4, 7 and 14 days after autoreplantation of upper 1st molar into their own position. The maxilla were disected included both side of 1st molar. The collected tissue were processed from demineralization to paraffin embeding as usual procedure, and the specimens were prepared with Hematoxylin-Eosin stain for the light microscopic evaluation. The results of this study were as follows : 1. There was no significant differences between control and experimental site on 1 and 2 days after replantation of tooth. In the case of 4th days, the evidence of tissue regeneration were observed on experimental site to compare the controls. New osteoid were revealed on high concentration of BMP at 7 days after replantation, and it became more obvious at 14 days, 2. The effect of the rh-BMP-4 coated on root surface was revealed slight influences for the prolifertion of cells of periodontium and tissue regeneration as dose-dependent pattern. 3. Bony ankylosis was observed between alveolar bone and root surface due to the remarkable amount of osteoid formation on the 14 days after replantation of root. In the conclusion, it was suggested that topical application of the rhBMP-4 on the root surface has influence on the periodontal ligament and alveolar bone. The application method of BMP on the root should be designed with calculation of proper concentration.

        백서의 치주인대세포와 두개관세포의 혼합배양이 석회화과정에 미치는 영향

        김지숙,박준봉,이만섭,권영혁,허익,임상철,Kim, Ji-Sook,Park, Joon-Bong,Lee, Man-Sup,Kwon, Young-Hyuk,Herr, Yeek,Lim, Sang-Cheol 대한치주과학회 1997 Journal of Periodontal & Implant Science Vol.27 No.4

        This study was performed to evaluate the effect of mixed culture of rat's calvaria cells and periodontal ligament cells on calcification. These cells have been known to do important role on the periodontal tissue regeneration, especially alveolar bone and cementum. Experimental groups were made which based on the different rate of rat's calvaria cells and periodontal ligament cells, and then these cells were cultured with Dulbecco's Modified Eagle's Medium contained with 10% fetal bovine serum, $50{\mu}g/ml$ ascorbic acid, and 10mM/ ml $Na-{\beta}-glycerophosphate$. Each group was characterized by examining the cell proliferation rate, amount of total protein synthesis, alkaline phosphatase activity, and the number of calcified nodules in vitro. In cell proliferation rate , the cells of control groups were cultured Dulbecco's Modified Eagle's Medium contained with 10 % fetal bovine serum. The results were as follows : 1. The cell proliferation rate in control groups decreased stastically significantly along with the decrease of the rate of bone cells at 7 day and 20 day(P < 0.01). 2. The cell proliferation rate in experimental groups decreased stastically significantly along with decrease of the rate of bone cells at 3 day and 14 day(P < 0.01). 3. The amount of total protein synthesis was significantly decreased along with decrease of the rate of bone cells at 3 day and 6 day(p < 0.01). 4. Alkaline phosphatase activity showed reverse time dependent pattern and was significantly decreased along with decrease of the rate of bone cells during the experimental periods (P < 0.01). 5. Calcified nodules were observed in group 1 (Rat calvaria cells alone) for the first time, and the number of calcified nodule decreased stastically significantly along with the decrease of the rate of bone cells at 12 day(P < 0.01). From the above results, When bone cells and periodontal ligament cells were mixed cultured, the cell proliferation rate was mostly dependent on the actual rate of bone cells and same pattern was showed in amount of total protein synthesis, alkalinephosphatase activity, and the number of calcified nodules. And the calcified nodule forming capacity of bone cells was inhibited by periodontal ligament cells
