본 연구에서는 우리나라에서 발생한 저체중아 출생 집계 자료를 공간적으로 지도화하기 위한 기법들을 검토 비교하고, 이를 기반으로 우리나라의 LBW 지도를 작성하였다. 표준화사망률이나 조사망률 등은 역학 분야에서 지속적으로 광범위하게 사용되고 있는 지표이다. 그러나 이러한 표준화사망률은 집계 단위의 샘플 수에 영향을 많이 받는다는 단점을 가지고 있다. 이에, 본 연구에서는 베이지언 기법을 활용하여 샘플 수에 따른 통계적 변동성을 감소시키고자 하였다. 이를 위해 경험적 베이지언 기법과 풀 베이지언 기법을 모두 활용하였고, 결과적으로 유사한 통계량을 산출한 것을 확인할 수 있었다. 반면, SMR 기반의 통계량은 높은 분산을 가지고 있음을 확인하였다. 연구의 결과에 따른 통계 지도는 우리나라 저체중아 출생의 높은 위험도를 가지는 지역들을 파악할 수 있도록 한다.

Since the active enhancement of large-scale apartment development in 1970, apartment complexes in Korea have shown considerable changes throughout, with respect to its planning and design. Depending on the government legislations, and economical and social issues of its time, apartments have been designed to respond to varying demands of the society; from minimal unit design to overall masterplan. As existing researches regarding development of apartment planning are conducted in individual and distinct manner, not only is it difficult to find cases of an overall critical analysis of apartment complexes, it is also rare to look for research that deals with a greater urban context, nor the geographical location of the site. With specific focus on apartments in the metropolitan, the focus of this research lies in critically analyzing the qualities of outdoor spaces within an apartment complex, its generational change and interpreting the value it holds for the society. With regards to analyzing its outdoor features, the core of this study deals with applying space syntax, based on the configurational properties of spatial constituents. The results of this research have some implications that the accessibility change of apartment outdoor spaces was examined through quantitative analysis, and the changes of it by time were clarified in detail. And objective and quantitative approaches were employed for an alternative to the methods used in existing related researches.

아파트는 우리나라 주거의 반수이상이 공급되어 있으며, 가장 선호하는 주거유형으로 자리매김 되고 있다. 이처럼 주거의 대부분을 차지하고 있는 아파트 내부공간이 최근에는 트렌드 차별차로 다양한 변화를 자랑하고 있지만 기본적인 법적 요구공간과 설계치수만을 적용하고 있는 상황이다. 주거에서 가장 중요한 의미는 가족이 단란하게 생활하는 공간이며 사회생활의 긴장을 완화시키는 기능이라 할 수 있을 것이다. 또한 주거공간은 가족 구성원간 상호작용과 자아정체감을 갖는데 영향을 주고 있으며 공간의 기본조건 중 능률성은 동선과 사용공간, 가전제품, 가구치수는 주거공간의 면적과 칫수에 영향을 미치고 있다. 아파트의 내부공간구조 자체가 서구에서 도입된 형태로 우리나라의 신체적 치수적용에 부조화를 초래하였으며 최근에는 다시 인체치수의 변화로 이와 관련하여 대한 건축계획에서도 적절한 주거공간의 구성을 위한 인체공학적 적합성에 근거한 주거공간 계획 기준을 제시하고자 한다.

The purpose of this study is to investigate and analyze the compositional elements of plan of art museums by selecting architectural works, which have strong symbolic meaning when evaluating value, from architectural works by Louis Kahn. First, the centrality of artworks, which are being displayed at the Yale Art Gallery, is complex. It includes three patterns of Void (spatial) Centrality+Symbolic Centrality+Functional Centrality among the five patterns suggested in this study. Second, the ratio system of interior space, which is expressed in the extension of the Yale Art Gallery, can be classified into the floor and walls. The floor used the square 1:1 ratio system. The ceiling used the grid patterns of equilateral triangles (regular tetrahedrons). It was applying a geometric ratio system when creating forms by using one side as a beam and the other sides as decorations of the ceiling. Third, the contours of interior space, which were expressed in Kahn's works, used the method of forming separate space according to the contouring rule (structural unit) defined by columns, and they were used in constructing the entire space through the integration of separate spaces. Fourth, according to the characteristics that were expressed by artworks displayed within the Yale Art Gallery Extension, the concept of accessibility was not as clear as that of residential buildings, because an approach of respecting existing architecture and context was used, rather than the starting point of interior space, or differentiated circulation, which has the function of a determined position.

Land is the only immovable property that can be used, as a means for agricultural production as well as a means for mortgage for financing industrial or commercial enterprises. Spatial technologies play a key role in managing our land, water and natural resources. Cadastral data is a major component for the development of Land Information System. Therefore, systematic land registration system based on accurate and scientific cadastral map are found inevitable for poverty alleviation, good governance and women empowerment through security of their rights on property, as well as the planning and development of a sustainable environmental protection within Metropolitan city. Digital cadastral parcel is the fundamental spatial unit on which database is designed, created, maintained and operated. Availability of accurate and updated cadastral maps is a primary requisite for successful planning, policy formulating and maintenance of city utility services, which need cadastral and utility information together. Flawed cadastral maps can put land, revenue and taxation system at stake. Kathmandu the capital city of Nepal still is lacking utility maps combining cadastral information with the utility. There is an urgent need to have an effective, accurate and easy to access land revenue and utility services system within the urban areas which could be achieved after the production of reliable base maps and land registration system to guarantee land allocation and property rights which can well be achieved by digital conversion and correction of base cadastral maps. This paper highlights the drawbacks of the conventional cadastral maps and the possible advantages of digital cadastral maps over these. Also the problems, issues and implications during digital conversion and creating database of the same will be discussed.

HDR(high dynamic range) 렌더링 기술은 다이내믹 레인지가 9 log unit이 넘는 휘도 범위의 일반 장면을 눈으로 보는 장면의 느낌과 최대한 유사하게 일반적인 영상매체에 출력이 가능하도록 8 bit해상도의 다이내믹 레인지로 변환하는 기술이다. 최근 가장 우수한 성능을 보이는 iCAM06 알고리듬은 iCAM (Image Appearance Modeling)과 CIECAM02를 토대로 만들어 졌으며, 기존 iCAM 모델에서는 제대로 고려하지 못한 공간 필터 링 (spatial filtering) 처리와 여러 시각현상을 고려 하여 설계하였다. 그러나 iCAM06 모델은 상당히 뛰어난 성능을 가지고 있음에도 불구하고 몇 가지 문제점을 가지고 있는데, 그 중의 하나가 사용자 설정 변수들이다. iCAM06에서 필요한 입력 변수들은 렌더링 영상에 큰 영향을 끼치지만, 실험적인 최적치로 결정되는 모호한 변수들이다. 본 논문에서는 iCAM06모델에서 사용되는 사용자 설정 입력 변수들에 대해 다양한 시조건이 고려된 최적의 값을 제공할 수 있도록 정량화된 수식을 제공하고, 또한 개선된 모델을 통하여 향상된 톤 압축의 가시성 결과를 다양한 조건에서의 HDR 영상으로 확인하였다.

To understand the composition and community changes of benthic species by water depth (5 m, 20 m, 30 m) in the cage facilities, net substrate made of fish cages were installed at intervals of 2 months from March to September 2019, which is the main period of sessile organism recruitment. Water temperature and salinity varied in the ranges of 1~5℃ and 1~4 mg/L at 5 m from June to August, respectively, and less difference was observed according to water depth in other investigation periods. A total of 37 benthic animals were recruited, and Kamptozoa unid., Caprella scaura and Jassa slatteryi were verified during the entire study period. Mytilus galloprovincialis, a Mediterranean mussel, showed seasonality dominant only from spring to early summer (March to July). The community structure classified by temporal and spatial factors, and Bugula neritina, Kamptozoa unid., and Sertularella sp. contributed to the formation of the community. The depth of 5 m was exposed to environmental changes in water temperature and salinity temporally, so there was a seasonal variation in the composition of the sessile organism, but at depths of 20 m and 30 m, there was less significant environmental change and it showed relatively stable than 5 m.
