The purpose of the current study was to select vulnerable regions with insufficient child care services based on an in-depth investigation of diverse regional characteristics and to establish a practical goal for the expansion of public child care centers through identifying priority regions in foremost need of public child care centers out of the vulnerable regions. The vulnerable regions were selected from both urban and rural areas with particular criterions to determine their critical situation. First of all, the number of children aged zero to five, private and public child care centers, and capacity and enrolment of the regional child care center were selected from towns (Eup) and townships (Myeon) within rural areas and neighborhoods (Dong) within urban areas to calculate the capacity fulfillment. Specifically, a dense population of low-income families inhabited within urban areas defined the region's vulnerable status for the analysis, whereas poor accessibility of a child care center within rural areas correspond to the lack of child care services. The analytical result displayed that a total of 456 towns and townships did not acquire child care centers. Out of 456 towns and townships, 162 were selected as priority regions. On the other hand, 546 neighborhoods corresponding to upper 30 percentiles of urban area where children receive basic subsidy for low income families were selected as vulnerable regions. Out of 546 neighborhoods, 243 were selected as priority regions according to the analytical result.

In this study, non-point pollution sources in the Yeongsan river basin are analyzed; then, the priority regions (areas divided on a small scale) of management are selected for efficient water management of the Seungcheon and Jooksan reservoirs, which were constructed as one of the 4 major rivers restoration projects. The priority regions are decided by using the criteria of the excessive rate of target water quality, non-point pollution load per unit area, total TP load and down flow distance. The results of this study are as follows. The upper 10% of the priority regions for non-point pollution management includes YB15, YB05, YB10, YB24, YB14 and YB11 for the Seungcheon reservoir watershed, and YC24, YC25, YC30, YC34, YC22 and YC17 for the Jooksan reservoir watershed. However, a few regions in each of the Seungcheon and Jooksan reservoirs need to be selected in higher order, and the non-point pollution removal facilities in the regions need to be installed with respect to budget, urgent matter, and so on.

Citizens' demand for public CCTVs continues to rise, along with an increase in variouscrimes and social problems in cities. In line with the needs of citizens, the Seoul Metropolitan Government began installing CCTV cameras in 2010, and the number of new installations has increased by over 10% each year. As the large surveillance system represents a substantial budget item for the city, decision-making on location selection should be guided by reasonable standards. The purpose of this study is to improve the existing related models(such as public CCTV priority location analysis manuals) to establish the methodology foranalyzing priority regions ofSeoul-type public CCTVs and propose new mid- to long-term installation goals. Additionally, using the improved methodology, we determine the CCTV priority status of 25 autonomous districts across Seoul and calculate the goals. Through its results, this study suggests improvements to existing models by addressing their limitations, such as the sustainability of input data, the conversion of existing general-purpose models to urban models, and the expansion of basic local government-level models to metropolitan government levels. The results can also be applied to other metropolitan areas and are used by the Seoul Metropolitan Government in its CCTV operation policy

Mixed raster content 모델 기반의 영상 부호화는 전경과 배경 레이어에 빈 영역인 don't care region (DCR)이 발생하게 되며, 이 영역에 대한 신호 채움 방식에 따라 전체적인 부호화 성능이 큰 영향을 받게 된다. DCR을 채우기 위한 대부분의 기존 기법들은 홀 주변 기존 영역의 특성을 효율적으로 이용하지 않아 신호 채움 후에도 기존 신호 영역에 존재하던 고주파 성분이 반영될 뿐 아니라, DCR 경계에서의 신호 불연속으로 인해 고주파 성분이 추가적으로 발생한다는 문제점을 갖고 있다. 이 문제를 해결하기 위해 본 논문은 우선순위 기반의 적응적 영역 확장법을 이용한 새로운 DCR 채움 알고리즘을 제안한다. 제안 알고리즘은 분수령 알고리즘을 이용하여 DCR의 각 홀 픽셀에 대한 신호 특성을 판단한 후, 이를 토대로 영역 채움의 우선순위를 결정한다. 이 우선 순위를 기반으로 영역 확장을 수행함으로써 고주파 성분을 포함하고 있는 영역의 확장이 최소화되어 전체적인 부호화 효율이 향상될 수 있다. 실험 결과를 통해 제안 알고리즘이 비교 대상 알고리즘에 비해 효율적인 신호 채움으로 우수한 부호화 성능을 가짐을 보인다.

The purpose of the present study is to confirm, through quantitative indices, changes arising with the implementation of urban regeneration projects, with a specific focus on the case of Dongnam-gu, Cheonan, one of the 13 priority rgions in urban regeneration. By utilizing quantitative data including resident population, floating population, revenue, number of small business persons, number of startup companies, and number of licensed buildings, the study confirmed changes in Dongnam-gu and other urban regeneration areas. The study compared monitoring results and implemented project policies to confirm changes within the area as a result of project implementation. Additionally, resident perception toward business districts was surveyed to confirm changes in perception and opinion, and monitoring indices were used to confirm changes as a result of project implementation. Accordingly, the study presented a plan to carry out the assessment of urban regeneration projects, which can be employed as data for conducting future urban regeneration projects. Urban regeneration projects are carried out for the long-term. Therefore, based on monitoring and investigative data, they require constant policy suggestions and periodic monitoring in accordance with changes resulting from project implementation. With regards to the effective range of urban regeneration projects, the study confirmed the possibility of an effect not only in the area of project implementation but also in surrounding areas. However, because the study merely confirms changes in Dongnam-gu, Cheonan, additional research is necessary to ascertain assessment plans suitable to the different types and regional characteristics of urban regeneration projects.

To establish a monthly data collection planning for the Ocean Scanning Multispectral Imager (OSMI), we have examined the global patterns of three impacting factors: pigment concentration, cloud cover, and sun glint. Other than satellite mission constraints (e.g., duty cycle), these three factors are considered critical for the OSMI data collection. The Nimbus-7 Coastal Zone Color Scanner (CZCS) monthly mean products and the International Satellite Cloud Climatology Project (ISCCP) monthly mean products (C2) were used for the analysis of pigment concentration and cloud cover distributions, respectively. And the monthly simulated patterns of sun glint were produced by performing the OSMI orbit prediction and the calculation of sun glint radiances at the top-of-atmosphere (TOA). Using monthly statistics (mean and/or standard deviation) of each factor in the above for a given 10$^{\circ}$ latitude by 10$^{\circ}$ longitude grid, we generated the priority map for each month. The priority maps of three factors for each month were subsequently superimposed to visualize the impact of three factors in all. The initial results illustrated that a large part of oceans in the summer hemisphere was classified into the low priority regions because of seasonal changes of clouds and sun illumination. Sensitivity tests were performed to see how cloud cover and sun glint affect the priority determined by pigment concentration distributions, and consequently to minimize their seasonal effects upon the data collection planning.

본 논문에서는 인간 시각 체계에 기반하여 주관적 화질의 열화없이 전송 정보량을 효과적으로 줄일 수 있고, 또한 전송 정보량을 조절할 수 있는 영역기반 초적속 부호화에 적합한 새로운 계층적 영상 분할 알고리즘을 제한한다. 제안한 알고리즘은 각 단계에서 수리 형태학에 기반한 영상 분할과 인간 시각 체계를 고려한 영역 볍합 고조로 이루어져 있다. 영상분할은 3단계의 계층적 구조로 이루어져 있으며, 영역 병합은 각 단계에서 인간 시각 체계에 기반하여 인간 시각이 구분할 수 없는 두 인접 영역의 쌍들을 추출한 후 영역 병합을 수행한다. 이때 인간 시각 체계에 기반하여 병합할 영역을 추출하고 제안한 병합을 우선 순위 함수에 의한 병합 우선 순위에 따른 영역 볍합ㅇ르 차례로 수행하여 영역의 수를 효과적으로 줄임으로써 영역기반 초저속 부호화시 과다한 윤곽선 정보로 인한 병목현상을 개선할 수 있다. 그리고 각 단계에서의 영역 병합시 정보량 조절 요소 값에 따라 전송 정보량을 조절할 수 있어 기존의 방법보다 유연한 분할 구조를 나타낸다. 실험을 통하여 제안한 방법은 기존의 방법보다 PSNR 및 주관적 화질은 유사하나, 전송할 윤곽선 정보는 상당히 줄일 수 있어 영역기반 초적속 부호화를 위한 효율적 영상 분할 알고리즘임을 알 수 있다.
