공간정보는 정보의 공유 및 개방, 융 복합 활용 등에 있어서 상위정책과의 연계성을 높일 뿐만 아니라 시민의 능동적 참여와 빅데이터를 연계한 창조적 활용에 기여할 수 있다는 점에서 지방자치단체 공간정보정책의 중요성은 크다. 하지만 수치지형도를 포함한 기본공간정보의 갱신, 공간정보 서비스 발굴, 공간정보 공유 및 협력 등 지방자치단체 공간정보 정책 수립은 미흡한 실정이다. 본 연구에서는 지방자치단체의 공간정보정책 개선방안을 도출하기 위해 중앙정부와 지방자치단체의 공간정보정책 및 시스템을 비교하고 지방자치단체 공간정보정책 시행계획과 서울시 32개 공간정보시스템 활용설문을 분석하였다. 연구결과 지방자치단체의 공간정보정책 개선을 위해 업무 부서와 연계하여 준공도면 등을 이용한 기본도의 수시 갱신, 국가공간정보통합체계를 통한 최신 공공부문 공간정보의 확보, 공간정보 플랫폼을 통한 정보의 공유, 공간정보 기반 정책 참여 관련 성공 사례의 벤치마킹 등이 제시되었다. Local governments' spatial information policies are very important in that it can increase the relatedness to upper policy regarding the share, openness and converged utilization of spatial information and contribute to voluntary participation and creative uses linked to big data. However, local governments' spatial information policies require enhancement since it need to update framework spatial data, to derive spatial information service and to share the data. In this research, we compared the spatial information policies and related systems of central and local governments, and analyzed the local governments' spatial information policy enforcement plans and the Seoul metropolitan government's utilization survey on 32 spatial information systems. In the result, for the improvement of local governments' spatial policies, on-demand updating of base map using the as built drawings linked to field work departments, securing up-to-date public domain spatial information through the NSDI system, sharing of spatial information based on the spatial information platform and benchmarking of best practices related to the spatial information based policy participation are suggested.

Purpose: We retrospectively analyzed the radiographic and clinical results after the first ray of forefoot osteotomy using low profile wedge plate without additional cancellous bone grafting for pes planus correction. Materials and Methods: Twenty-four patients were enrolled in this study. Medial cuneiform opening wedge osteotomy was performed in 12 patients (Cotton osteotomy, group C) and first metatarsal base osteotomy was performed in 12 patients (group MT). Results: On average, the wedge size was 5.61 mm (5~6 mm). The mean time to radiographic union was 3.18 and 3.27 months in groups C and MT, respectively. Postoperative talonavicular coverage angle, talo-first metatarsal angle (anteroposterior), talo-first metatarsal angle (lateral), talo-calcaneal angle (lateral), medial cuneiform height, and American orthopaedic foot, as well as ankle society midfoot scale were significantly improved in both groups. Nonunion, delayed union or fixation failure was not presented in our series. Conclusion: We have shown that low profile wedge plate was effective in the case of first ray forefoot osteotomy for pes planus correction without any additional cancellous bone grafting.

최준영,안희찬,신명진,서진수,Choi, Jun Young,Ahn, Hee Chan,Shin, Myung Jin,Suh, Jin Soo 대한족부족관절학회 2017 대한족부족관절학회지 Vol.21 No.1

Purpose: Anterior drawer and varus stress radiographs are commonly to diagnose chronic lateral ankle instability. We compared the preoperative stress radiographs with the intraoperative radiographs under anesthesia to determine the accuracy and efficacy of stress radiographs in an outpatient clinical environment. Materials and Methods: Data was collected from patients who underwent a modified $Brostr{\ddot{o}}m$ operation for painful chronic unilateral lateral ankle instability between January 2014 and June 2016. Subjects were divided into three groups-complete tear, partial tear, and instability without rupture-according to the status of preoperative MRI findings of the anterior talofibular ligament. The anterior drawer and varus stress radiographs were taken preoperatively and intraoperatively under anesthesia. Results: Ninety-six patients, with a mean age of 29.63 years, were enrolled. There were 39, 46, and 11 patients in the complete tear, partial tear, and instability without rupture groups, respectively. On the anterior drawer and varus stress radiographs of the affected limb, talar anterior translation and varus tilting were significantly increased by 2.56 mm and $2.0^{\circ}$. The gaps between the unaffected limbs were also increased by 2.47 mm and $1.32^{\circ}$ after anesthesia. Although the stress radiographs were taken under anesthesia, the results were often smaller than the diagnostic value. Conclusion: Stress radiographs for painful chronic lateral ankle instability taken at the outpatient clinic might be inaccurate for diagnosis.

용액공정을 이용한 ZnSnO 산화물 반도체 박막 트랜지스터에서 Mg 첨가에 따른 영향

최준영,박기호,김상식,이상렬,Choi, Jun-Young,Park, Ki-Ho,Kim, Sang-Sig,Lee, Sang-Yeol 한국전기전자재료학회 2011 전기전자재료학회논문지 Vol.24 No.9

Thin-film transistors(TFTs) with magnesium zinc tin oxide(MZTO) channel layer are fabricated by solution-process. The threshold voltage (Vth) shifted toward positive directly with increasing Mg contents in MZTO system. Because the Mg has a lower standard electrode potential (SEP) than Sn, Zn, thus degenerate the oxygen vacancy ($V_O$). As a result, the Mg act as carrier suppressor and oxygen binder in the MZTO as well as a Vth controller.

비 중심 Si δ-doping 층을 갖는 GaAs-Al_xGa_1-x 양자우물에서 전계에 따른 전자 분포

최준영,전상국,Choi, Jun-Young,Chun, Sang-Kook 한국전기전자재료학회 2007 전기전자재료학회논문지 Vol.20 No.1

The electric property in the $GaAs-Al_{x}Ga_{1-x}$ quantum well with the Si ${\delta}-doping$ layer in a non-central position is studied through the effect of the electric field intensity on the electron distribution. The finite difference method is used for the calculation of the subband energy level and its wavefunction. In order to account for the change of the potential energy due to the charged particles, the self consistent method is employed. As the Si ${\delta}-doping$ layer becomes closer to the heterojunction interface, the electrons less affected by Coulomb scattering are greatly increased under the external electric field. Therefore, the high speed device is suggested due to the fact that the high mobility electrons can be increased by positioning the ${\delta}-doping$ layer in the quantum well and by applying the electric field intensity.

Purpose: Several techniques have been introduced for correction of pes cavo-varus deformity. We retrospectively reviewed and compared the data of patients who underwent 1st metatarsal osteotomy alone, Dwyer's osteotomy alone, and 1st metatarsal osteotomy combined with Dwyer's osteotomy to determine the effect on radiographic parameters. Materials and Methods: Data on 28 cases in 27 consecutive patients recruited from 2006 to 2014 who underwent 1st metatarsal osteotomy alone (group F), Dwyer's osteotomy alone (group H), or 1st metatarsal osteotomy followed by Dwyer's osteotomy (group HF) with a minimum 1-year follow-up were reviewed retrospectively. Results: Calcaneal pitch angle on the standing foot lateral radiographs was significantly decreased after the operation in groups H and HF whereas Meary angle was decreased in groups F and HF. Hindfoot alignment angle and ratio on the hindfoot alignment view were improved in groups H and HF. Maximal medial cuneiform height reduction was observed in group HF. 1st ray was significantly shortened in groups F and HF. Conclusion: Combined forefoot and hindfoot operation took the largest correction power of all radiologic parameters.

To solve the housing supply problems which are combined with economic, social, environmental and urban spatial structural aspects, it is needed to analyze housing supply based on the analysis model. This study aims to draw the construction of the housing geospatial information for housing supply model. For these purposes, we construct the housing geospatial information and draw case studies on information utilization based on the precedent studies and relevant systems about housing geospatial information. From the result, we construct the geospatial information according to spatial unit and draw standardization of connected information between housing supply information and housing geospatial information. Also we found that it is essential to use a building and parcel level housing geospatial information for housing supply. In the future, it will be needed to construct the housing supply information from qualitative aspect for dwelling and to establish a utilization strategy.

공진주파수 스펙트럼법을 이용한 Composite Resonator 구조에서 압전박막의 특성 평가에 대한 연구

최준영,장동훈,강성준,윤영섭,Choi Joon Young,Chang Dong Hoon,Kang Seong Jun,Yoon Yung Sup 대한전자공학회 2005 電子工學會論文誌-SD (Semiconductor and devices) Vol.42 No.1

공진주파수 스펙트럼법을 이용하여 ZnO 와 AIN 압전박막의 임피던스 특성 및 전기기계결합계수 특성에 대해 조사하였다. 압전박막의 두께가 얇을수록 전체적인 임피던스 응답 피크의 크기가 감소하였으며, 기판의 두께가 얇을수록 응답 피크의 모드 수가 감소하는 것이 관찰되었다. 입력 Kt² 값으로부터 평가된 Kt² 값을 통해 압전박막의 두께보다 기판의 두께 변화에 대한 영향이 더 큼을 알 수 있었고, 기판의 acoustic 임피던스에 의해서도 Kt² 값이 감소함을 알 수 있었다. 전극 효과가 첨가되면 임피던스 응답 피크의 크기가 감소하였으며, 전극의 acoustic 임피던스가 커짐에 따라 응답피크는 더 작아졌다. 공진주파수 스펙트럼법에서 전극은 질량부하로 고려되기 때문에 전극 효과가 첨가된 경우 Keff² 값은 증가하며, 전극의 acoustic 임피던스가 크면 그 효과는 더 커졌다. 공진주파수 스펙트럼법을 이용한 시뮬레이션을 통해 기판, 압전체, 전극으로 이루어진 composite 공진기의 특성 분석과 설계까지도 가능함을 알 수 있었다. We studied the characteristics of impedance and electromechanical coupling coefficient in ZnO and AIN thin films by using resonance frequency spectrum method. The response peak of impedance decreased with the decrease of thickness of piezoelectrics, the number of mode of response peak decreased with the decrease of substrate thickness. An error of Kt² estimated from input Kt² increased as the thickness of piezoelectrics decreased and the thickness of substrate increased. Also, the error was increased in case of a large acoustic impedance of substrate. It was found that the composite resonator operating in optimized condition could be designed through the resonance frequency spectrum analysis of composited resonator consisted of piezoelectric thin film and substrate.

공간정보의 폭발적 증가와 공간정보 활용 기술의 발전으로 국토의 비교우위를 유지하기 위한 공간정보와 도시계획 및 부동산 정보 융복합 수요가 증가하고 있다. 본 논문에서는 국토 경쟁력 강화를 위해 필요한 융복합 공간정보의 장래 국토공간 계획 및 이용 활용도를 전망해 보았다. 이를 위해 국토, 주택분야 공기업인 한국토지주택공사(LH)의 장래 2029년까지 6대 분야별 미래사업을 도출하였다. 또한 문헌조사를 통해 도출한 7종의 융복합 공간정보의 미래사업 분야별 활용도를 설문조사하여 국토주택개발 분야의 미래 활용을 분석해 보았다. 분석결과 3D, 모바일 데이터, 정형 빅데이터, 지오센서, 참여형 공간정보 순으로 활용도가 높은 것으로 나타났고, 사업분야에서는 도시 및 지역개발이 활용도가 높은 것으로 나타났다. 미래 융복합 공간정보 활성화를 위해서는 토지이용 이외에 해양이용, 연안이용, 지하공간 등 균형있는 국토이용 공간정보의 구축이 필요한 것으로 나타났다. Due to explosively increasing utilization in spatial information and a rapid development in geospatial technology related to national territorial and housing, there are increasing demands for converging spatial information on not only urban planning and real estate data but also newly generated data from smart phone, GPS to achieve comparative advantage of national territory. In this paper, we prospect the utilization of Converged Spatial Information(CSI) to future national territorial planning for the purpose of enhancing territorial competitiveness. For this purpose, considering the Korea Land and Housing corporation(LH) takes charge most of government's land and housing development projects, CSI usage of this company's 6 future business domains until 2029 were used as a case study. Also, 7 CSIs derived from literature review were surveyed to find the degree of CSI utilization in the national territorial future. In the analysis result, it was found that 3D data and mobile data among others have higher degree of utilization, and urban and regional development is the most highly utilizable domain for CSIs. After all, to revitalize the use of CSI in national territorial future, it is required to do a balanced construction of territorial use spatial information about marine use, coastal use, underground space besides land use.
