본 연구는 폭염 취약지역을 도출하고, 폭염 피해와의 공간적 일치성 분석을 통해 공간 유형화 및 정책적 방향성에 대해 논의하고자 한다. 연구 방법은 IPCC의 기후변화 취약성 평가와 공간통계 비교분석을 활용하였으며, 폭염이 가장 극심했던 2018년을 포함하는 5개년(2015~2019)의 전국 시군구를 대상으로 하였다. 폭염 취약성은 다양한 요소 중 폭염 영향을 나타내는 폭염일수(노출)가 가장 큰 영향을 미치고 있었으며, 폭염에 대한 민감도와 적응 능력은 지역의 특성에 따라 경향성이 나타나는 것으로 확인되었다. 폭염 취약성과 피해의 관계는 공간적 일치성을 통해 4개 유형으로 구분하였으며, 취약성과 피해가 정의 관계를 가지는 Hot to Hot, Cold to Cold 유형과 역의 관계를 가지는 Hot to Cold, Cold to Hot 유형을 도출하였다. 이는 유형별로 지역의 특성과 현황이 상이하므로 유형에 따라 개선을 위한 정책과 연구의 방향성을 달리 설정해야 한다는 시사점을 남긴다. 해당 연구는 폭염 취약성과 피해를 함께 고려하여 지역을 유형화하고, 유형별 대응 방향성에 대해 살펴본 점에서 추후 폭염 관련 정책 수립에 기초자료로 활용되기를 기대한다.

본 연구에서는 2004년 1월부터 2007년 12월까지의 기간을 대상으로 우리나라 지역 노동시장의 일자리결합함수를 추정해보았다. 일자리 결합에 영향을 미치는 지역효과를 통제하기 위한 LSDV 기법과 지역 자료를 사용할 경우 발생하는 공간적 자기상관의 문제를 해결하기 위한 공간오차모형을 활용하였다. 주요 결과는 다음과 같다. 첫째, 지역 노동시장을 대상으로 일자리결합함수를 추정한 결과 이론과 합치하는 일자리 결합구조를 확인할 수 있었고, 구인기업의 채용이 구직자의 취업보다 상대적으로 용이하다는 결과를 얻었다. 둘째, 구직자 수와 일자리 수가 동일한 조건에서 수도권이 다른 지역에 비해 일자리 결합이 원활한 것으로 나타났다. 셋째, 인근 지역의 구직자 수가 적을수록, 그리고 공석의 일자리 수가 많을수록 당해 지역내에 거주하는 구직자의 취업건수가 증가하는 결과를 보여 일자리 결합과정에서 발생하는 지역간 파급효과를 포착할 수 있었다.

The purpose of this study is to provide a reference for stage space planning in modern theaters by analyzing and understanding stage components in terms of spatial composition, purposes, and correlation between them, and collecting various opinions from stage managers an directors. The findings are as follow: the determination of the size of proscenium arch is crucial, and it needs to be considered not only with the genre of the performance and the number of seats, but also with the size of the stage facility. The two-dimensional size of proscenium arch affects the scale of stage area in three-dimensional way; the size of main stage comes from the width of the arch, and the length of set battens comes from the stage width, and so on. The height of the arch affects the elevation of gridiron, and the height of the building itself ultimately. The number and length of the set battens are directly linked to the size of the winch room, and so is the number of the winches to the Mcc panel room. The 1st level gallery supplying power to lighting equipment needs to be wide enough for staffs to work with various equipments effectively and safely. Degree of practical usage of under-stage machinery turned out to be very low. In order to cut unnecessary waste and cost, the characteristics of the theater must get set first, and experts who know how stage works need to get involved in planning stage.

디지털 홀로그래피가 아날로그 홀로그래피와 비슷한 품질을 나타내기 위해서는 $1{\mu}m$의 픽셀피치를 가지고 있는 대면적 SLM 개발이 필수적이다. 이러한 대면적 초고해상도 SLM을 구현하기 위해서는 최근 미세 픽셀 기술이 급격히 발전하고 있는 대면적 지향의 평판디스플레이 기술을 기반으로 개발되어야 할 것으로 생각된다. 디스플레이 기술을 기반으로 스티칭 기술 등의 포토리소그래피 기술과 수직채널 TFT등의 구동 소자 기술, 고굴절율 이방성을 가지는 액정 소재 기술, 모듈 기반의 구동 기술 등을 집약하여 $1{\mu}m$급의 픽셀 피치를 가지는 대면적 초고해상도 SLM을 개발 중이다. 이렇게 개발된 초고해상도 대면적 SLM은 홀로그램 영상 재현 이외에도 다양한 광학 소자로 응용이 기대된다.

Photoconductor for direct detection flat-panel imager present a great materials challenge, since their requirements include high X -ray absorption, ionization and charge collection, low leakage current and large area deposition. Selenium is practical material. But it needs high thickness and high voltage in selenium for high ionization rate. We report comparative studies of detector sensitivity. One is an a-Se with $70{\mu}m$ thickness on glass. The other has hybrid layer of depositting ZnS phosphor with $100{\mu}m$ on a-Se. The leakage current of hybrid is similar to it of a-Se, but photocurrent is lager than a-Se. Both of them have high spatial resolution, but hybrid has higher sensitivity than a-Se at comparable bias voltage.

The plane strain analysis for simulating the stretch/draw forming operation of arbitrarily-shaped tool profiles and arbitrarily draw-in conditions is introduced. An implicit, incremental, updated Lagrangian formulation is employed, introducing a rigid-viscoplastic constitutive equation. Contact and friction are considered through the mesh-normal, which compatibly describes arbitrary tool surfaces and FEM meshe without depending on the explicit spatial derivatives of tool surfaces. The FEM formulation is tested in the sections automotive inner panel and two-side draw-in. Not only the excellent agreement between measured and computed strains in the stretched section is obtained, but also the numerical stability of current formulation is verified in the two-side draw-in section.

The Soubise Mansin which construction ended in the latter half of 1730s has several rooms which symbolize Rococo which appeared in the 18 century. The work of the Soubis Mansion done by an architect, Boffrand , is a significant work in which he had introduced a new style of building , Rococo, based on a style of Regency, thereby showing a big leaf in that kind of art. In other words, with the elements already established in the days of Regency-white wood panel, gold molding, mirror technique, etc. -and the characteristics of unprecedent, outstanding spatial forms and Rococo decoration introduced. Rococo had enjoyed its peak of full flourish within the moderation of being never excessively magnificent, beautiful, and dignified. It is a remarkable thing that a model of such perfect ideal beauty was suggested even in the begining state of Rococo and it is deemed that such a point resulted in such influence on other places like the Versalilles Palace, etc.

Recently Song and Cheon (2006) and Cheon and Lim (2009) developed the generalized maximum entropy(GME) estimator to solve ill-posed problems for the regression coefficients in the simple panel model. The models discussed consider the individual and a spatial autoregressive disturbance effects. However, in many application in economics the data may contain nested groupings. This paper considers a two-way error component model with nested groupings for the ill-posed data and proposes the GME estimator of the unknown parameters. The performance of this estimator is compared with the existing methods on the simulated dataset. The results indicate that the GME method performs the best in estimating the unknown parameters in terms of its quality when the data are ill-posed.

The plane strain analysis for simulating the stretch/draw forming operation with an arbitrarily-shaped tool profile is introduced. An implicit, incremental, updated Lagrangian formulation with a rigid-viscoplastic constitutive equation is employed. Contact and friction are considered through the mesh-normal, which compatibly describes arbitrary tool surfaces and FEM meshes without depending on the explicit spatial derivatives of tool surfaces. The linear line elements are used for depicting the formed sheet, based on membrane approximation. The FEM formulation is tested in the sections of automotive inner panel and two-side draw-in. Not only the excellent agreement between measured and computed strains is obtained in the stretched section, but also the numerical stability of formulation is verified in the draw-in section.

This study analyzed the change of flowout and suspend solid in Andong and Imha basin according to the climate change to develop evaluation index about turbid water occurrence possibility and to support the countermeasures for turbid water management using GIS-based Soil and Water Assessment Tools (SWAT). MIROC3.2 hires model values of A1B climate change scenario that were supplied by Intergovernmental Panel on Climate Change (IPCC) were applied to future climage change data. Precipitation and temperature were corrected by applying the output value of 20th Century Climate Coupled Model (20C3M) based on past climate data during 1977 and 2006 and downscaled with Change Factor (CF) method. And future climate change scenarios were classified as three periods (2020s, 2050s, 2080s) and the change of flowout and suspended solid according to the climate change were estimated by coupling modeled value with SWAT model.
